Patent Application
20220015606
The subject matter herein generally relates to a manufacturing equipment, and more particularly to a sticky mat changing device for automatically changing a sticky mat.
Sticky mats are generally cut into rectangular pieces and placed directly on the ground to remove foot contaminants. The user usually changes the sticky pad manually after a long time.
Implementations of the present technology will now be described, by way of embodiment, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series, and the like.

The foot board 17 is disposed on the top frame 13, partially covers the top of the receiving chamber 18, and is used for the user to step on. In the embodiment, the foot board 17 includes a plurality of cross bars arranged at intervals. In other embodiments, the foot board 17 can be a whole plate.
The frame 10 further includes a plurality of reinforcing columns 19. The plurality of reinforcing columns 19 are disposed on the bottom frame 11 and connected to two sides of the bottom frame 11. In this embodiment, the frame 10 includes two reinforcing columns 19, the two reinforcing pillars 19 correspond in position to two sides of the foot board 17 respectively.
The frame 10 is made of a material with high tensile strength, such as iron, stainless steel, etc.

The sticky mat changing device 100 further includes a first cover plate 51 and the second cover plate 53. The first cover plate 51 corresponds in position to the unreeling roller 30, is disposed on the top frame 13, and partially covers the top of the receiving chamber 18. The first cover plate 51 protects the unreeling roller 30 to prevent the user from stepping on it. The first cover plate 51 is located on one side of the foot board 17. A first gap 511 is formed between the first cover plate 51 and the foot board 17 for the sticky mat 200 to pass through. The second cover plate 53 corresponds in position to the reeling roller 40, is disposed on the top frame 13, and partially covers the top of the receiving chamber 18. The second cover plate 53 protects the reeling roller 40 to prevent the user form stepping on it. The second cover plate 53 is located on a side of the foot board 17 facing away from the first cover plate 51. A second gap 531 is formed between the foot board 17 and the second cover plate 53 for the sticky mat 200 to pass through. In the embodiment, the first cover plate 51 and the second cover plate 53 are movably arranged on the top frame 13 and can be opened relative to the top frame 13. The material of the first cover 51 and the second cover 53 may be wood, iron, or the like.
The sticky mat changing device 100 further includes a third cover plate 55. The third cover plate 55 is disposed on sides of the top frame 13 and the bottom frame 11 to cover side faces of the receiving chamber 18.
When in use, the sticky mat 200 is wound on the unreeling roller 30 to form a coil stock, and one end of the sticky mat 200 passes through the first gap 511 and the second gap 531 in turn and is wound on the reeling roller 40. As a result, portion of the sticky mat 200 is exposed outside the frame 10 and supported on the foot board 17 for removing foot contaminants. When the used sticky mat 200 needs to be replaced, the unreeling roller 30 and the reeling roller 40 are rotated, and the reeling roller 40 winds up the used sticky mat 200, and the unreeling roller 30 unwinds the sticky mat, thus a portion of the unused sticky mat 200 is re-supported on the pedal 17.

The sticky mat changing device 100 further includes a setting module 70. The setting module 70 sets a time interval. The setting module 70 is electrically connected to the control module 60 and controls the rotation each of the unreeling roller 30 and the reeling roller 40 according to the time interval.
The sticky mat changing device 100 further includes a timer 80. The timer 80 times a rotation interval of the unreeling roller 30 and the reeling roller 40 and starts timing when the unreeling roller 30 and the reeling roller 40 stop rotating. The timer 80 is electrically connected to the control module 60. The control module 60 controls each of the unreeling roller 30 and the reeling roller 40 to rotate when the time interval has been reached. The control module 60 controls each of the unreeling roller 30 and the reeling roller 40 to rotate for a period of time to change the portion of the sticky mat 200 supported on the foot board 17.
The setting module 70 further sets a number of stamping. The control module 60 further controls the unreeling roller 30 and the reeling roller 40 to rotate when the number of stamping has been reached.
The sticky mat changing device 100 further includes a sensor 91 and a counter 93. The sensor 91 is disposed on the foot board 17 and senses whether the foot board 17 is stepped on. The counter 93 is electrically connected to the sensor 91 and counts the number of stamping according to a sensing result from the sensor 91. The counter 93 is electrically connected to the control module 60 and controls the unreeling roller 30 and the reeling roller 40 to rotate when the number of stamping has been reached.
In the embodiment, the sensor 91 is a pressure sensor. The pressure sensor senses a pressure change on the foot board 17. The counter 93 counts the number of stamping according to the sensed pressure change. When the counted number reaches the set number of stamping, the control module 60 controls each of the unreeling roller 30 and the reeling roller 40 to rotate for a period of time to rechange the portion of the sticky mat 200 supported on the foot board 17. When the unreeling roller 30 and the reeling roller 40 stop rotating, the counter 93 restarts to count, and the control module 60 controls each of the unreeling roller 30 and the reeling roller 40 to rotate again when the counted umber reaches the set number of stamping to rechange the sticky mat 200 supported on the foot board 17 again.
In an alternative embodiment, the sensor 91 is an infrared sensor. The infrared sensor senses the number of users on the foot board 17. The counter 93 counts the number of stamping according to the sensed number of users.
In the sticky mat changing device 100, the control module 60 controls each of the unreeling roller 30 and the reeling roller 40 to rotate to automatically change the portion of the sticky mat 200 supported on the foot board 17. The work efficiency is improved and the production cost is reduced.
While the present disclosure has been described with reference to particular embodiments, the description is illustrative of the disclosure and is not to be construed as limiting the disclosure. Therefore, those of ordinary skill in the art can make various modifications to the embodiments without departing from the scope of the disclosure as defined by the appended claims.
