Description

Technical Field

[0001] This utility model relates to the field of zipper manufacturing technology, specifically to a device for precise cutting and counting of zipper length. Background Technology

[0002] A zipper is a mechanical fastener consisting of two flexible strips with teeth and a sliding slider. The movement of the slider engages or disengages the teeth, thus enabling connection or opening. Widely used in clothing, bags, footwear, tents, and household goods, it is an indispensable and convenient connector in modern life. To improve production efficiency, zippers of the same model are typically produced in bulk and then cut into sections using a cutting device.

[0003] Existing zipper cutting devices control the cutting length and number of zippers by cooperating with a conveying component and a cutting component, thereby achieving the effect of obtaining zippers of a specified length and quantity. However, if the distance between the drive roller and the pressure roller is too large or too small, it will affect the conveying of the zippers. Furthermore, the distance between the drive roller and the pressure roller used for conveying in the conveying component is inconvenient to adjust, which reduces the efficiency of zipper production. Therefore, we need to propose a precise zipper length cutting and counting device. Utility Model Content

[0004] The purpose of this invention is to provide a precise zipper length cutting and counting device. Through the configuration of the conveying component, the drive roller and the pressure roller rotate simultaneously, driving the zipper body to move, thereby conveying the zipper body to the cutting component. By adjusting the component settings, two sets of second rotating rods can be rotated clockwise or counterclockwise simultaneously, driving the lifting plate to move up and down. Simultaneously, the lifting plate moves up and down, driving the pressure roller to move up and down via the connecting plate, thus achieving rapid adjustment of the distance between the pressure roller and the drive roller. This allows the zipper cutting device to adapt to the production requirements of conveying different types of zipper bodies, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a zipper length precision cutting and counting device, comprising a base, a conveying assembly for conveying the zipper body is installed on the top of the base, an adjusting assembly is installed inside the conveying assembly, and a cutting assembly for cutting the zipper body is installed at one end of the conveying assembly; the conveying assembly includes a drive roller fixedly installed on a support frame, a drive roller rotatably installed through the inner wall of the support frame, a pressure roller rotatably installed on the lower inner wall of the support frame through a lifting groove, and one end of the zipper body passing through the gap between the drive roller and the pressure roller; the adjusting assembly includes two sets of second rotating rods rotatably installed on the inner wall of the support frame through four sets of support plates, a lifting plate is threadedly connected to the middle of the second rotating rod, and the top of the lifting plate is rotatably connected to both ends of the pressure roller through a connecting plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a device for precise cutting and counting of zipper length, including a base 1. A conveying component 2 for conveying the zipper body 3 is installed on the top of the base 1. An adjusting component 4 is installed inside the conveying component 2. A cutting component 6 for cutting the zipper body 3 is installed at one end of the conveying component 2. The conveying component 2 includes a drive roller 24 fixedly installed on a support frame 21. A drive roller 24 is rotatably installed through the inner wall of the support frame 21. A pressure roller 26 is movably installed on the lower inner wall of the support frame 21 through a lifting groove 25. One end of the zipper body 3 passes through the gap between the drive roller 24 and the pressure roller 26. The adjusting component 4 includes two sets of second rotating rods 45 rotatably installed on the inner wall of the support frame 21 through four sets of support plates 44. A lifting plate 47 is threadedly connected to the middle of the second rotating rod 45. The top of the lifting plate 47 is rotatably connected to both ends of the pressure roller 26 through a connecting plate 48.

[0023] In use, the drive roller 24 and the pressure roller rotate simultaneously with the conveying component, driving the zipper body 3 to move, thereby conveying the zipper body 3 to the cutting component 6. The cutting component 6 is then activated to cut the zipper, achieving the cutting effect. When it is necessary to adjust the distance between the drive roller 24 and the pressure roller 26, the two sets of second rotating rods 45 are rotated clockwise or counterclockwise simultaneously by the adjustment component 4, driving the lifting plate 47 to move up and down. Simultaneously, the lifting plate 47 moves up and down, driving the pressure roller 26 to move up and down through the connecting plate 48, thereby achieving the effect of quickly adjusting the distance between the pressure roller 26 and the drive roller 24, making the zipper cutting device adaptable to the production of different zipper models.

[0024] The adjustment assembly 4 also includes a second motor 41 bolted to the outside of the support frame 21. The output shaft of the second motor 41 is keyed to a first rotating rod 42 rotatably mounted inside the support frame 21. Two sets of driving wheels 43 are fixedly mounted in the middle of the first rotating rod 42. A set of driven wheels 46 are fixedly mounted at the bottom of each of the two sets of second rotating rods 45. The outer sides of the two sets of driving wheels 43 are respectively meshed with the outer sides of the set of driven wheels 46. When the second motor 41 is started, it drives the first rotating rod 42 to rotate, which in turn drives the two sets of driving wheels 43 to rotate. The rotation of the two sets of driving wheels 43 drives the two sets of driven wheels 46 to rotate. The rotation of the two sets of driven wheels 46 drives the two sets of second rotating rods 45 to rotate. The rotation of the second rotating rods 45 indirectly drives the pressure roller 26 to move. By controlling the rotation direction of the second motor 41, the distance between the pressure roller 26 and the drive roller 24 is controlled, thereby achieving the effect of automatic control.

[0025] A first motor 23 is bolted to the outside of the support frame 21. The output shaft of the first motor 23 is keyed to one end of the drive roller 24. When the first motor 23 is started, the drive roller 24 is driven to rotate. The drive roller 24 and the pressure roller 26 press and squeeze the zipper body 3. While the drive roller 24 rotates, it works with the pressure roller 26 to move the zipper body 3, thereby achieving the effect of automatically transmitting the zipper body 3.

[0026] The output shaft of the first motor 23 is connected to the encoder 5 via gear transmission. The encoder 5 is installed on the outside of the support frame 21. The first motor 23 drives the drive roller 24 to rotate while simultaneously driving the encoder 5 to rotate via gear transmission. The encoder 5 rotates once when the drive roller 24 rotates once. At this time, the conveying length of the zipper is equal to the outer circumference of the drive roller 24. By setting the encoder 5, the conveying of the zipper body 3 stops after reaching the specified length, thereby achieving the effect of precise cutting of the zipper body 3.

[0027] Two sets of auxiliary rollers 22 are rotatably mounted on the inner wall of the support frame 21. One end of the zipper body 3 passes through the gap between the two sets of auxiliary rollers 22. The setting of the two sets of auxiliary rollers 22 can limit the movement of the zipper body 3 and improve the stability of the movement of the zipper body 3.

[0028] The cutting assembly 6 includes a fixed plate 61 fixedly installed on the top of the support frame 21. An electric push rod 62 that drives the cutter 63 to move is provided below the fixed plate 61. A guide plate 64 is fixedly installed on one side of the support frame 21. A positioning frame 65 is fixedly installed on the top of the guide plate 64. A collection box 7 is provided below the guide plate 64. When the electric push rod 62 is activated, the cutter 63 moves downward. The cutter 63 cuts the zipper body 3 that passes through the inside of the positioning rod. The cut zipper body 3 will automatically fall into the collection box 7 below through the guide plate 64, thereby achieving the effect of rapid cutting of the zipper body 3.

[0029] A counter 67 is fixedly installed on the inner side of the guide plate 64, and a limit rod 66 is fixedly installed on one side of the cutter 63. Each time the cutter 63 cuts, it will drive the limit rod 66 to press the switch of the counter 67 once, thereby achieving the effect of counting the number of zipper bodies 3 cut.

[0030] In practical use: One end of the zipper body 3 passes sequentially through the gaps between the two sets of auxiliary rollers 22, the gap between the drive roller 24 and the pressure roller 26, and the gap between the positioning frame 65. Then, the second motor 41 is started to rotate, indirectly driving the pressure plate and the drive roller 24 to press and adhere the zipper body 3. While the first motor 23 is started to drive the drive roller 24 to rotate, the zipper body 3 is moved. The distance moved by the zipper body 3 is measured by the encoder 5. When the moving distance is equal to the length to be cut, the feeding stops. The electric push rod 62 is started to drive the cutter 63 to move downward. The cutter 63 cuts the zipper body 3 that has passed through the inside of the positioning rod. The cut zipper body 3 will automatically fall into the collection box 7 below through the guide plate 64. After the cutter 63 automatically resets, the zipper body 3 continues to be fed, thereby achieving the effect of continuous feeding and cutting of the zipper body 3. Each cut will trigger the counter 67 to count, thereby achieving the effect of cutting and counting the zipper body 3 to a specific length.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
