The present invention relates to a curtain cutting machine, and more particularly to an automatic curtain cutting machine.
Curtains are applied to shield and decorate windows of a building, and a window blind is one of various types of curtains and is produced in a few lengths (i.e. lengths of a first rail, a second rail, and the multiple slats are equal to a width of each curtain). Thereby, each curtain is cut by users based on using requirements so as to match with a size of a window.
A conventional curtain cutting machine contains a base and a fixed cutting device arranged on an end of the base so that the fixed cutting device cuts a curtain having two symmetrical ends. For example, one of the two symmetrical ends of the curtain is cut, then the curtain is turned 180 degrees so as to cut its other end, thus cutting the curtain complicatedly and troublesomely.
To overcome above-mentioned problem, as shown in
In operation, the curtain is clamped by the first holder 93A and the second holder 93B so that when the curtain is moved to the first fixed cutting device 92A, the first measurement part 94A measures an end of the curtain which is cut, and the first holder 93A and the second holder 93B are fixed on the two guide rods 911 respectively so as to fix the curtain, then the first fixed cutting device 92A cuts the end of the curtain. Thereafter, the first holder 93A and the second holder 93B are released and move toward the second fixed cutting device 92B so that the second measuring rule 95B measures a desired length of the curtain, and the first holder 93A and the second holder 93B are mounted on the two guide rods 911 individually so as to fix the curtain. Then, the other end of the curtain over the desired length is cut. In contrast, the end of the curtain close to the second fixed cutting device 92B is cut, and the other end of the curtain proximate to the first fixed cutting device 92A is cut, wherein the second measuring part 94B measures the desired length of the curtain close to the second fixed cutting device 92B, and the first measuring part 95A measures the desired length of the curtain close to the first fixed cutting device 92A.
As cutting the curtain, the curtain is clamped and is actuated by the first holder 93A and the second holder 93B so as to move to one of the two fixed cutting devices (such as the first fixed cutting device 92A or the second fixed cutting device 92B) and to be measured, and the first holder 93A and the second holder 93B are locked on the two guide rods 911 respectively so as to fix the curtain and to cut the end of the curtain. Thereafter, the first holder 93A and the second holder 93B are released so as to move toward the other of the two fixed cutting devices (such as the second fixed cutting device 92B or the first fixed cutting device 92A) and to be measured, then the first holder 93A and the second holder 93B are locked on the two guide rods 911 individually so as to fix the curtain. Thereafter, the other end of the curtain is cut. However, the curtain is cut by two fixed cutting devices (i.e., the first fixed cutting device 92A and the second fixed cutting device 92B) and is clamped by the first holder 93A and the second holder 93B. Furthermore, the first holder 93A and the second holder 93B are locked and released repeatedly, thus having high fabrication cost and inconvenient operation.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary objective of the present invention is to provide an automatic curtain cutting machine which cuts two ends of a curtain automatically so as to avoid turning the curtain, thus cutting the curtain easily and quickly.
Another objective of the present invention is to provide an automatic curtain cutting machine which contains a cutting device moving on a base so as to cut by the two ends of the curtain, such that only the cutting device is required so as to simplify the automatic curtain cutting machine and to reduce fabrication cost.
To achieve above-mentioned objectives, an automatic curtain cutting machine provided by the present invention contains: a base, a support unit, a cutting device, a displacement device, and at least one clamp device.
The base axially extends and is configured to parallelly hold a curtain on the base, and the curtain moves on the base.
The support unit includes multiple support sets movably arranged on the base, and the support unit is configured to support the curtain.
The cutting device is mounted and moves on the base, and the cutting device includes a first space, a second space, and at least one cutter.
The first space is configured to pass through the curtain and connects with the second space so that each of the multiple support sets moves through the second space, and the at least one cutter is fixed outside the first space and vertically moves along a track of the curtain, wherein the track is a datum line so that an end of the curtain over the datum line is cut.
The displacement device is disposed on the cutting device and moves with the cutting device, and the displacement device is configured to move the multiple support sets which correspond to a moving track of the at least one cutter.
The at least one clamp device is configured to clamp the curtain so that the curtain is cut.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, a preferred embodiment in accordance with the present invention.
With reference to
The base 10 is elongated and axially extends, and the base 10 includes two slide rails 11 arranged between two ends of the base 10 respectively.
The support unit 20 includes multiple support sets 21 movably arranged on the base 10, each of the multiple support sets 21 has at least one orifice 211 defined proximate to a bottom of each support set 21, at least one part of the multiple support sets 21 is in an inverted L shape and has an accommodation groove 212 defined on a top part of the at least one support set 21.
The cutting device 30 is mounted and moves on the two slide rails 11 of the base 10, and the cutting device 30 includes a first space 31, a second space 32, two cutters 33, a holding plate 34, and a third space 35. A bottom of the first space 31 flushes with a top of each support set 21, the second space 32 is connected with the first space 31 so that each support set 21 moves through the second space 32, and the two cutters 33 are fixed beside two sides of the first space 31 and move vertically along the base 10 so as to cut a workpiece. The holding plate 34 is arranged below the first space 31 and has a first moving mechanism 341 formed on a bottom thereof so as to actuate the holding plate 34 to lift and descend, wherein when the holding plate 34 is actuated by the first moving mechanism 341 to lift, a top of the holding plate 34 flushes with the accommodation groove 212 of the at least one part support set 21.
The displacement device 40 is disposed on the cutting device 30, and the displacement device 40 moves the support sets 21 corresponding to the two cutters 33 as the cutting device 30 moves. The displacement device 40 includes a second moving mechanism 41, an actuation seat 42 driven by the second moving mechanism 41 so as to move along the base 10, a movable drive rod 43 secured on the actuation seat 42, a holder 44 configured to hold the multiple support sets 21, and two springs 45 configured to push the multiple support sets 21 to move back toward original positions respectively.
The at least one clamp device 50 includes a first clamping part 50A and at least one second clamping part 50B (in this embodiment, the at least one clamp device 50 includes a first clamping part 50A and two second clamping parts 50B), wherein the first clamping part 50A is fixed on one of the multiple support sets 21 of the support unit 20, the first clamping part 50A has two third moving mechanisms 51A and two press elements 52A driven by the two third moving mechanism 51A to vertically move along the base 10. When the cutting device 30 slides, it avoids moving through the first clamping part 50A by way of the third space 35. The two second clamping parts 50B are arranged beside the first space 31 of the cutting device 30 so as to move, when the cutting device 30 moves. Each of the two second clamping parts 50B has a fourth moving mechanism 51B and an abutting plate 52B driven by the fourth moving mechanism 51B to move close to or away from the first space 31.
The movable positioning device 60 is mounted on an end of the base 10, and the movable positioning device 60 includes a fifth moving mechanism 61 and a fixing sheet 62 actuated by the fifth moving mechanism 61 so as to move on the base 10.
