Description

Technical Field

[0001] This utility model relates to the field of zipper production technology, specifically to a zipper tape cutting device. Background Technology

[0002] A zipper is a connector that uses continuously arranged teeth to join or separate items. It is now widely used in clothing and various bags and boxes. A zipper tape consists of two tapes, each with a row of metal or plastic teeth, used to connect the edges of an opening. A sliding element pulls the two rows of teeth into an interlocking position to close the opening.

[0003] During the production process, zipper tape needs to be cut. Currently, zippers are typically spaced apart on the fabric tape, with a blank section between each zipper. Cutting is done in this blank section to obtain zippers of equal length. However, the fabric tape has a certain degree of flexibility, making it prone to shifting and skewing during cutting. This results in uneven cuts and generally poor cutting quality. Utility Model Content

[0004] The purpose of this invention is to provide a zipper tape cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a zipper tape cutting device, comprising a workbench, a cutting component and a tensioning component on the workbench, the cutting component comprising a bracket fixedly mounted on the rear side of the workbench, a standard cylinder fixedly mounted above the bracket, a push plate fixedly mounted below the piston rod of the standard cylinder, and a cutter detachably mounted below the push plate, the workbench having a through-cut groove located directly below the cutter, the tensioning component comprising a pneumatic gripper A fixedly mounted on the workbench and a pneumatic gripper B slidably mounted on the bracket, the pneumatic gripper A and pneumatic gripper B being located on the front and rear sides of the cutter respectively, and a slot communicating with the cutting groove being provided on the rear side wall of the workbench.

[0006] Preferably, the workbench is provided with an installation groove, the bottom of the pneumatic gripper A is located in the installation groove and is fixedly connected to the workbench, and the upper and lower grippers of the pneumatic gripper A are located on the upper and lower sides of the top wall of the workbench, respectively.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1-4As shown, this utility model discloses a zipper tape cutting device, including a workbench 1. The workbench 1 is provided with a cutting component and a tensioning component. The cutting component includes a bracket 2 fixedly installed on the rear side of the workbench 1, a standard cylinder 3 fixedly installed above the bracket 2, a push plate 4 fixedly installed below the piston rod of the standard cylinder 3, and a cutter 5 detachably installed below the push plate 4. The workbench 1 has a cutting groove 6 directly below the cutter 5. The tensioning component includes a pneumatic gripper A7 fixedly installed on the workbench 1 and a pneumatic gripper B8 slidably installed on the bracket 2. The pneumatic gripper A7 and the pneumatic gripper B8 are respectively located on the front and rear sides of the cutter 5. A slot 9 communicating with the cutting groove 6 is opened on the rear side wall of the workbench 1.This utility model also includes a control component, which includes a PLC controller and several solenoid valves. The standard cylinder 3, pneumatic gripper A7, and pneumatic gripper B8 are all connected to the solenoid valves via air pipes. The solenoid valves and the linear module 11 are all connected to the PLC controller via wires. The PLC controller, solenoid valves, and linear module 11 are all connected to a power source via wires. The solenoid valves are connected to an air source via air pipes. In use, the zipper tape to be segmented is placed above the workbench 1, with the bottom of the zipper tape in contact with the workbench 1 and the rotating roller 15. The stop bars 16 are positioned on the left and right sides of the zipper tape, and the pneumatic grippers are engaged. The upper and lower grippers of claw A7 are positioned on the upper and lower sides of the zipper tape, respectively. The rear end of the zipper tape is then pulled above the cut groove 6. The linear module 11 is activated, moving the pneumatic gripper B8 forward. The pneumatic gripper B8 passes through the slot 9 and enters the cut groove 6. At this point, the upper and lower grippers of pneumatic gripper B8 are positioned on the upper and lower sides of the zipper tape, respectively. Pneumatic gripper B8 is activated to close its grippers and clamp the rear end of the zipper tape. The linear module 11 is activated, moving pneumatic gripper B8 backward and the zipper tape backward, so that the blank section of the zipper tape is above the cut groove 6. Pneumatic gripper A7 is activated to close its grippers and clamp the middle of the zipper tape. At this point, the zipper tape is clamped on both sides of the cutter 5. The standard cylinder 3 is activated, pushing its piston rod downwards, causing the push plate 4 and cutter 5 to move downwards, allowing the cutter 5 to insert into the cutting groove 6 to cut the blank section of the zipper tape. Because the zipper tape is clamped, movement and skewing during cutting are avoided, ensuring consistent cuts and improving cutting quality. After cutting, the pneumatic gripper B8 is closed, opening the gripper and allowing the cut zipper tape to fall downwards. A conveyor belt or collection box can be installed below the support 2 to collect the zipper tape. The pneumatic gripper A7 is closed, opening the gripper, and the standard cylinder 3 is activated. The piston rod of the pre-cylinder 3 retracts upward, allowing for the next cut. In summary, this invention has the beneficial effect of preventing the zipper tape from shifting or skewing during cutting, thus improving cutting quality. It solves the problem that the flexible fabric tape is prone to shifting or skewing during cutting, leading to inconsistent cuts and generally poor cutting quality. (The functions to be achieved by each piece of hardware in this invention are supported by a large number of mature technologies. The essence of this invention lies in its specific application.
