In this embodiment, the cleaning tank 10 is constructed as a closed box structure. The cleaning tank is provided on two sides thereof with doors that can be opened and closed. The door is driven by a vertical cylinder so that the mattress cleaning device of the present invention can be used with other cleaning systems, such as subsequent rinsing devices, drying devices, etc. The openable and closable door also allows the cleaning tank 10 to have an independent cleaning space. The water stains during cleaning will not splash into the environment or other cleaning systems.
Multiple groups of conveying assemblies 20 are horizontally spaced and arranged in the cleaning tank 10 and are located between two openable and closable doors to form a conveying channel. Multiple alternate spaces are formed between multiple groups of conveying assemblies 20. Preferably, one alternate space is formed between adjacent conveying assemblies 20. The conveying assembly 20 comprises a conveying shaft 21, a conveying belt 22, and a power structure. The conveying belt 22 is sleeved on the conveying shaft 21, and the power structure is connected to the conveying shaft 21 to drive the conveying shaft 21 to rotate so as to drive the conveying belt 22 to operate so as to move and transport the mattress, as shown in
The first brush roller set 30 includes multiple movable brush rollers 31 and one or more first brush rollers 32, and the movable brush rollers 31 and the first brush rollers 32 are rotatably provided in multiple alternate spaces, respectively. The distance between adjacent moving brush rollers 31 is greater than or equal to the length or width of the mattress, and at least one first brush roller 32 is provided between adjacent moving brush rollers 31. The movable brush roller 31 is movable up and down in a direction perpendicular to the conveying channel with respect to the conveying assembly 20 to wash the front face and the rear face of the mattress at the same time. When the movable brush roller 31 moves to be flush with or slightly lower than the converting assembly 20, it can also assist in cleaning the lower end face of the mattress. The first brush roller 32 serves to wash the lower end face of the mattress, and a part of the surface of the first brush roller 32 is always convex to the upper surface of the conveying assembly 20 during the rotation of the first brush roller 32 to wash the lower end face of the mattress. In the present embodiment, the movable brush roller 31 and the first brush roller 32 each comprise a roller body and a brush provided on the surface of the roller body for brushing the mattress, i.e. when the first brush roller 32 is provided, the roller body thereof needs to be always lower than the upper surface of the conveying assembly 20, but the brush on it needs to protrude slightly above the upper surface of the conveying assembly 20 so as to contact and brush the surface of the mattress. Each first brush roller 32 and each movable brush roller 31 is extended in the width direction of the conveying channel, and the extending length is preferably greater than or equal to the width of the conveying channel (greater than or equal to the length or width of the mattress) so that the first brush roller 32 and the movable brush roller 31 can completely wash the respective entire end faces when the mattress is moved on the conveying belt 22.
The second brush roller set 40 is rotatably provided above the conveying assembly 20 to clean the upper end face of the mattress. The second brush roller set 40 includes multiple second brush rollers 41 arranged in line in the transporting direction of the conveying assembly 20 and offset from the movable brush roller 31 such that the movable brush roller 31 does not interfere with the second brush roller 41 when moving up and down. In order to improve the cleaning effect, at least one second brush roller 41 is correspondingly provided directly above each conveying assembly 20. Each second brush roller 41 is likewise provided to be extending in the width direction of the conveying channel.
The third brush roller set 50 is rotatably provided at two sides in the transporting direction of the conveying assembly 20 to wash two sides faces of the mattress. The third brush roller set 50 comprises multiple third brush rollers 51 arranged in the transporting direction of the conveying assembly 20, and each third brush roller 51 is arranged to extend in the moving direction of the movable brush roller 31 by an extending length greater than or equal to the thickness of the mattress.
In this embodiment, the second brush roller 41 and the third brush roller 51 also comprise a roller body and a brush provided on the surface of the roller body for brushing the mattress, the self-rotation of the roller body driving the surface brush to brush the mattress.
Because the thicknesses and sizes of the mattresses vary, the brush roller needs to adapt thereto. Therefore, the brush roller is typically movably mounted within the cleaning tank 10 to fit the surface of the mattress. In this embodiment, the first brush roller 32 and the second brush roller 41 need only to be mounted on a sliding block that is movable up and down perpendicular to the transporting direction of the conveying assembly 20 so as to monitor and contact the mattress to begin brushing via a sensor. Since the third brush roller 51 is used for brushing end faces on two sides of the mattress, if the width of the mattress becomes small, it is necessary to bring the third brush rollers 51 on two sides close to each other, and the movement of the third brush roller 51 can also be achieved by means of a sliding block and a sliding rod. Such kind of moving mode can adopt the existing technology, which will not be described in detail herein.
In this embodiment, the first brush roller set 30, the second brush roller set 40, and the third brush roller set 50 each includes a corresponding drive structure that drives the corresponding brush roller set to rotate or move to brush the surface of the mattress. Preferably, the first brush roller set 30 and the second brush roller set 40 self-rotate in the same direction to improve the stability of the mattress during moving cleaning. If the self-rotation is reversed and the mattress is relatively near the front, the first brush roller set 30 and the second brush roller set 40 can easily continue to push the mattress forward.
In a specific embodiment, the number of the conveying assemblies 20 is four, thereby forming a total of five alternate spaces. The number of the first brush rollers 32 is two, and the number of the movable brush rollers 31 is two, which are respectively arranged in the above-mentioned five alternate spaces, and the moving brush rollers 31 and the first brush rollers 32 are arranged at intervals in a staggered manner; for example, one end of the conveying assembly 20 is provided with one movable brush roller 31 and the other end is provided with one first brush roller 32. The number of the second brush rollers 41 is four, corresponding to four conveying assemblies 20, respectively. The number of the third brush rollers 51 is 16, which are respectively arranged on two sides of the second brush roller 41, and one second brush roller 41 corresponds to four third brush rollers 51. In some other embodiments, the number of brush rollers may be adapted as desired, which will not be limited herein.
The spray assembly 60 includes multiple spray pipes 61 arranged above the conveying assembly 20 to spray the mattress with detergent or clear water. A water storage tank 11 is provided above the cleaning tank 10, and the water storage tank 11 is provided in communication with the spray assembly 60. In order that the cleaned sewage does not contaminate the environment or the tank, a water containing tank 12 is provided in the cleaning tank 10 below the conveying channel. The projection of the conveying assembly 20 in the vertical direction falls partially or entirely within the water containing tank 12. The bottom of the water containing tank 12 is inclined with respect to the ground to facilitate the discharge of sewage.
The mattress enters the conveying assembly 20 in the cleaning tank 10; the brush roller set in the cleaning tank 10 brushes the mattress; when the mattress is washed, a diluent with a detergent is sprayed from the spray pipe 61 according to needs; through the movement of the conveying belt, the first brush roller set 30 is used to brush the lower end face and the front end face and the rear end face of the mattress, the second brush roller set 40 is used to brush the upper end face of the mattress, and the third brush roller set 50 is used to brush the end faces on two sides of the mattress. In this embodiment, the brush roller set may be driven to rotate to brush the surface of the mattress. In other embodiments, the brush roller set may not actively rotate, and the mattress is conveyed back and forth by the conveying assembly 20 so as to rotate the brush roller set to brush the surface of the mattress, thereby achieving full cleaning of the six sides of the mattress.
Compared with the prior art, the mattress cleaning device according to the embodiment of the present invention has a high degree of automation and a good cleaning effect by providing the first brush roller set, the second brush roller set, and the third brush roller set, and simultaneously washing the lower end face of the mattress, the front end face and the rear end face of the mattress, the upper end face of the mattress, and the end faces on two sides of the mattress respectively, and automatically cleaning the entire surface of the mattress at one time without overturning the mattress.
