Description

Technical Field

[0001] This utility model relates to the field of zipper testing technology, specifically a bidirectional pneumatic clamp type zipper reciprocating testing machine. Background Technology

[0002] With zippers widely used in various garments, bags, and other daily necessities, their durability and performance directly affect product quality and lifespan. Therefore, durability testing of zippers is a crucial step in ensuring their quality. Existing zipper testing equipment primarily measures the number of times a zipper can be pulled back and forth to determine its durability, but this method has certain limitations.

[0003] Traditional testing tools cannot realistically simulate the stress conditions of zippers in actual use, such as whether the zipper strap is taut or slack, and the specific mechanical situation when the zipper head is pulled outward or pressed during use. As a result, the test results cannot fully reflect the mechanical changes that the zipper may encounter during actual use, thus affecting the accurate evaluation of zipper performance. Utility Model Content

[0004] This invention addresses the technical problems existing in the prior art by providing a bidirectional pneumatic clamp type zipper reciprocating testing machine. This solves the problem that existing zipper durability test results cannot fully reflect the mechanical changes that zippers may encounter during actual use, thus affecting the accurate evaluation of zipper performance.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a bidirectional pneumatic clamp type zipper reciprocating testing machine, comprising:

[0006] Two wall panels positioned opposite each other;

[0007] A base plate, which is fixed between two wall panels;

[0008] A first linear module is disposed between two wall panels, wherein the movable end of the first linear module can move back and forth between the two wall panels;

[0009] A first clamping component is disposed on the moving end of the first linear module;

[0010] The second clamping assembly is disposed on one side of the wall panel and is located on the movement trajectory of the first linear module moving end;

[0011] The second linear module is located below the first linear module and is mounted on the base plate;

[0012] A lifting assembly is disposed on the moving end of the second linear module;

[0013] A clamp is disposed on the lifting end of the lifting assembly.

[0014] The beneficial effects of this utility model are:

[0015] 1) The first clamping component and the second clamping component are respectively clamped on both sides of the zipper belt, and the distance between the first clamping component and the second clamping component is adjusted by the moving end of the first linear module, so as to achieve precise control of the tightness or looseness of the belt. It can not only adapt to zippers of different sizes and specifications, but also simulate different tension states that the belt may experience in actual use.

[0016] 2) Next, after the clamp is held in place by the hole on the zipper head, the lifting assembly is used to drive the clamp to move up and down, applying vertical force to the zipper head. This simulates the real scenario of a person pulling outward or pressing the zipper head inward, allowing the tensile force between the zipper head and the zipper belt to be realistically reproduced during the test. With the drive of the second linear module, a horizontal force is applied to the zipper head, which can realize the back-and-forth pulling action of the zipper head. This fully simulates the mechanical action of the zipper in actual use, ensuring that the test results have higher realism and accuracy. This makes the zipper durability test not only more accurate, but also fully reflects the durability performance of the zipper in different usage environments.

[0017] Based on the above technical solution, the present invention can be further improved as follows.

[0018] Furthermore, both the first clamping assembly and the second clamping assembly employ cylinder grippers.

[0019] Furthermore, the lifting assembly is configured as an electric push rod mechanism.

[0020] Furthermore, the clamp includes a first clamping rod, a second clamping rod, a torsion spring, and an anti-detachment protrusion. One end of the first clamping rod is fixed to the drive end of the electric push rod machine, and the second clamping rod crosses and is hinged to the first clamping rod.

[0021] Furthermore, the torsion spring is disposed at the hinge joint between the first clamping plate and the second clamping plate.

[0022] Furthermore, the anti-detachment protrusion is fixed to one side of the first clamping plate and the second clamping plate.

[0023] The beneficial effect of adopting the above-mentioned further solution is that pressing down one end of the second clamp can open the gap between the other ends of the first clamp and the second clamp, thereby aligning the anti-detachment protrusion with the hole of the zipper head. After releasing one end of the second clamp, the torque force of the torsion spring will automatically cause the anti-detachment protrusion to penetrate the hole of the zipper head, firmly fixing the zipper head. The elastic torque of the torsion spring provides a continuous and stable clamping force, ensuring that the zipper head will not fall off due to external force, thereby achieving precise positioning and fixing of the zipper head.

[0029] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0030] With zippers widely used in various garments, bags, and other daily necessities, their durability and performance directly affect product quality and lifespan. Therefore, durability testing of zippers is a crucial step in ensuring their quality. Existing zipper testing equipment primarily measures the number of times a zipper can be pulled back and forth to determine its durability, but this method has certain limitations.

[0031] Traditional testing tools cannot realistically simulate the stress conditions of zippers in actual use, such as whether the zipper belt is taut or slack, and the specific mechanical situation when the zipper head is pulled outward or pressed during use. As a result, the test results cannot fully reflect the mechanical changes that the zipper may encounter during actual use, thus affecting the accurate evaluation of zipper performance. In response, the inventor of this utility model proposes a bidirectional pneumatic clamp type zipper reciprocating testing machine to solve the above problems.

[0032] The present invention provides the following preferred embodiments.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the bidirectional pneumatic clamp type zipper reciprocating testing machine includes:

[0034] Two opposing wall panels 10;

[0035] The base plate 20 is fixed between the two wall panels 10;

[0036] A first linear module 30 is disposed between two wall panels 10, wherein the movable end of the first linear module 30 can move back and forth between the two wall panels 10;

[0037] The first clamping component 40 is disposed on the moving end of the first linear module 30;

[0038] The second clamping assembly 50 is disposed on one side of the wall panel 10 and is located on the movement trajectory of the moving end of the first linear module 30.

[0039] The second linear module 60 is located below the first linear module 30 and is mounted on the base plate 20.

[0040] Lifting assembly 70, which is disposed on the moving end of the second linear module 60;

[0041] Clip 80 is installed on the lifting end of the lifting assembly 70;

[0042] The first clamping component 40 and the second clamping component 50 are respectively clamped on both sides of the zipper belt, and the distance between the first clamping component 40 and the second clamping component 50 is adjusted by the moving end of the first linear module 30, thereby achieving precise control of the tightness or looseness of the belt. It can not only adapt to zippers of different sizes and specifications, but also simulate different tension states that the belt may experience in actual use.

[0043] Secondly, after the clip 80 is clamped into the hole on the zipper head, the lifting component 70 drives the clip 80 to rise and fall, applying up and down force to the zipper head. This simulates the real scenario of a person pulling outward or pressing the zipper head inward, allowing the tensile force between the zipper head and the zipper belt to be realistically reproduced during the test. With the drive of the second linear module 60, a horizontal force is applied to the zipper head, enabling the zipper head to move back and forth. This fully simulates the mechanical action of the zipper in actual use, ensuring that the test results have higher realism and accuracy. This makes the zipper durability test not only more precise but also fully reflects the durability performance of the zipper under different usage environments.

[0044] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, both the first clamping assembly 40 and the second clamping assembly 50 use HFP6 40 model cylinder grippers.

[0045] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the lifting assembly 70 is a JC35W1 model electric push rod mechanism.

[0046] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the clamp 80 includes a first clamping rod 801, a second clamping rod 802, a torsion spring 803, and an anti-detachment protrusion 804. One end of the first clamping rod 801 is fixed to the drive end of the electric push rod machine. The second clamping rod 802 crosses and is hinged to the first clamping rod 801. The torsion spring 803 is located at the hinge between the first clamping plate and the second clamping plate. The anti-detachment protrusion 804 is fixed to one side of the first clamping plate and the second clamping plate.

[0047] Pressing down one end of the second clamp 802 will increase the distance between the other ends of the first clamp 801 and the second clamp 802, thereby aligning the anti-detachment protrusion 804 with the hole of the zipper head. After releasing one end of the second clamp 802, the torque force of the torsion spring 803 will automatically cause the anti-detachment protrusion 804 to penetrate the hole of the zipper head, firmly fixing the zipper head. The elastic torque of the torsion spring 803 provides a continuous and stable clamping force, ensuring that the zipper head will not fall off due to external force, thereby achieving precise positioning and fixing of the zipper head.

[0048] The specific working process of this utility model is as follows:

[0049] (1) Chain straps for securing zippers

[0050] First, the chain is clamped on both sides by two cylinder jaws.

[0051] (2) Fix the chain head

[0052] Pressing down one end of the second clamp 802 will open up the gap between the other ends of the first clamp 801 and the second clamp 802, so that the anti-detachment protrusion 804 is aligned with the hole of the zipper head. After releasing one end of the second clamp 802, the torque force of the torsion spring 803 will automatically cause the anti-detachment protrusion 804 to penetrate the hole of the zipper head and firmly fix the zipper head.

[0053] (3) Pull the chain head

[0054] By using the drive of the second linear module 60, a horizontal force is applied to the zipper head, which can achieve the action of the zipper head being pulled back and forth on the zipper belt.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
