Description

Technical Field

[0001] This utility model relates to the technical field of zipper testing equipment, and more specifically to a testing device for zipper tooth loss and arching. Background Technology

[0002] Zippers are connectors that use continuously arranged teeth to join or separate items, and are widely used in clothing, bags, tents, and other products. Missing teeth and arching are two defects in zippers. Missing teeth refers to the absence of a tooth in a continuous zipper chain; arching is characterized by a localized bulge or upward tilt of the teeth, preventing the zipper tape from fitting straight and properly, and may be related to poor injection molding of the teeth, uneven material shrinkage, or pressure during sewing.

[0003] Existing detection devices lack guiding mechanisms, which affects the detection results. For example, patent (authorization announcement number CN203310613U) discloses a detection device for detecting a small cat with a missing tooth in a zipper. Refer to the appendix of that patent. Figure 2 The lack of guiding devices on the left and right sides of the diagram prevents the zipper from being smoothly introduced into the first zipper head, and also prevents the zipper from being smoothly exited from the second zipper head. Therefore, it is necessary to improve the structure. Utility Model Content

[0004] The purpose of this utility model is to provide a detection device for chain tooth loss and arching in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A detection device for chain tooth loss and arching includes a support rod and a guide chain shaft, a detection table, and a guide chain wheel assembly arranged sequentially along the support rod.

[0007] One end of the connecting plate is screwed to the guide chain shaft, and the other end is connected to the support rod.

[0008] A sliding platform is located in the middle of the support rod, and the testing platform is slidably connected to the sliding platform. Mounting plates are located on both sides of the testing platform, and each mounting plate has a U-shaped notch for installing a slider. The U-shaped notch closer to the guide chain shaft is used to install an arched slider, while the U-shaped notch further away from the guide chain shaft is used to install a slider with missing teeth.

[0009] The guide shaft is provided with a guide groove, which is used to guide the zipper tape.

[0010] The connecting plate also has a waist-shaped hole in the middle, through which the connecting plate is screwed to the support rod. The waist-shaped hole increases the stability of the connection between the connecting plate and the support rod. Furthermore, it allows for fine-tuning of the connecting plate to adjust the guide shaft, ensuring it fits snugly against the zipper and preventing the zipper from slipping off.

[0011] The slide table includes two fixed seats, which are fixedly connected to the support rod. Two parallel slide rods are provided between the two fixed seats, and the slide rods are slidably connected to the fixed seats.

[0012] The fixed seat near the guide chain shaft is equipped with a spring, one end of which is connected to the fixed seat and the other end is connected to the testing table.

[0013] The support rod is equipped with a proximity switch at its bottom, and the detection platform is equipped with a sensing block at its bottom.

[0014] The detection platform has a through groove in the middle, a first recess at the bottom of the through groove, and two adjustable grooves at the bottom of the first recess. The through groove provides installation space for the slider, facilitating installation and preventing it from bumping against the detection platform. The adjustable grooves allow for easy adjustment of the sensor block's position relative to the detection platform, ensuring precise alignment between the proximity switch and the sensor block. Screws are installed within the adjustable grooves to secure the sensor block. The first recess provides space for the screws, preventing them from protruding above the bottom of the through groove and affecting subsequent slider installation.

[0015] The guide wheel assembly includes two guide sections, each adapted to one of the two zipper tapes, with guide wheels fitted onto each guide section. The guide wheels are rotatably connected to the guide sections. When the zipper tape passes through the guide wheels, the guide wheels rotate along the guide sections. The guide wheels reduce the friction between the zipper and the guide sections.

[0016] The support rod is equipped with a mounting bracket at its bottom. The mounting bracket is installed at the zipper outlet of the zipper machine, and the detection device is mounted on the zipper machine via the mounting bracket.

[0017] In this invention, a first positioning groove is provided at the connection between the mounting bracket and the support rod, and a second positioning groove is provided at the connection between the fixing seat and the support rod. The stability of the connection is increased by providing the first and second positioning grooves.

[0018] In this invention, a traction device (not shown in the attached drawings) is installed on one side of the guide chain shaft to traction the zipper belt. The traction device and its connection with the zipper belt are existing technologies and will not be described in detail in this invention. The two zipper belts pass through the guide chain wheel in sequence along the traction direction, then are introduced into the toothed zipper head, then into the arched zipper head, and finally exit through the guide chain groove. It should be noted that if the zipper belt teeth are arched, it will pass smoothly when passing through the toothed zipper head (that is, the toothed zipper head fails to detect the arched zipper belt). Therefore, an additional arched zipper head is needed to avoid missed detection.

[0019] When the zipper belt is pulled, it is taut. The detection platform compresses the spring. If no missing teeth or arching is detected, the sensor block moves away from the proximity switch. When a zipper belt with a missing tooth passes the missing pressure zipper head, the zipper drives the detection platform to continue compressing the spring, causing the sensor block to approach the proximity switch. The proximity switch sends a signal to the control device, controlling the traction device to stop working and reminding the staff to check and mark it. When an arched zipper belt passes the arched zipper head, the zipper drives the detection platform to continue compressing the spring, causing the sensor block to approach the proximity switch. The proximity switch sends a signal to the control device, controlling the traction device to stop working and reminding the staff to check and mark it.

[0020] The beneficial effects of this utility model are as follows:

[0021] This invention improves testing quality by setting guide shafts and guide wheel sets on both sides of the testing platform, which allows the zipper belt to be smoothly guided in and out of the zipper head. The waist-shaped hole increases the stability of the connection between the connecting plate and the support rod. On the other hand, the connecting plate can be finely adjusted to adjust the guide shaft, so that the guide shaft is close to the zipper and prevents the zipper from slipping off the guide shaft.

[0030] Example 1

[0031] like Figures 1 to 5 As shown, this embodiment provides a detection device for chain tooth loss and arching, including a support rod 1 and a guide shaft 2, a detection table 3, and a guide wheel group 4 arranged sequentially along the support rod 1;

[0032] One end of the connecting plate 5 is screwed to the guide chain shaft 2, and the other end is connected to the support rod 1;

[0033] A sliding platform is provided in the middle of the support rod 1, and the testing platform 3 is slidably connected to the sliding platform. Mounting plates 6 are provided on both sides of the testing platform 3. The mounting plates 6 have U-shaped notches 24 for installing the sliders. The U-shaped notches 24 near the guide chain shaft 2 are used to install the arched slider 7, and the U-shaped notches 24 away from the guide chain shaft 2 are used to install the toothed slider 8.

[0034] The guide shaft 2 is provided with a guide groove 9, which is used to guide the zipper tape.

[0035] The connecting plate 5 is also provided with a waist-shaped hole 11 in the middle, and the connecting plate 5 is connected to the support rod 1 by screws through the waist-shaped hole 11. By setting the waist-shaped hole 11, the stability of the connection between the connecting plate 5 and the support rod 1 can be increased. On the other hand, the connecting plate 5 can also be finely adjusted to adjust the guide shaft 2 so that the guide shaft 2 is close to the zipper tape and prevents the zipper tape from slipping off the guide shaft 2.

[0036] The slide table includes two fixed seats 12, which are fixedly connected to the support rod 1. Two parallel slide rods 13 are provided between the two fixed seats 12, and the slide rods 13 are slidably connected to the fixed seats 12.

[0037] A spring 14 is provided on the fixed seat 12 near the guide chain shaft 2. One end of the spring 14 is connected to the fixed seat 12 and the other end is connected to the detection table 3.

[0038] The support rod 1 is equipped with a proximity switch 15 at its bottom, and the detection platform 3 is equipped with a sensing block 16 at its bottom.

[0039] The detection platform 3 has a through groove 17 in the middle, and a first groove 18 at the bottom of the through groove 17. Two adjusting grooves 19 are located at the bottom of the first groove 18. The through groove 17 provides installation space for the slider (both arched and toothed sliders), facilitating slider installation and preventing it from colliding with the detection platform 3. The adjusting grooves 19 are designed to facilitate adjusting the installation position of the sensor block 16 on the detection platform 3, ensuring precise alignment between the proximity switch 15 and the sensor block 16. Screws are installed within the adjusting grooves 19 to secure the sensor block 16. The first groove 18 provides space for the screws, preventing them from protruding above the bottom of the through groove 17 and affecting subsequent slider installation.

[0040] The guide wheel assembly 4 includes two guide sections 20, each adapted to one of the two zipper tapes 10. Guide wheels 21 are fitted onto the guide sections 20. The guide wheels 21 are rotatably connected to the guide sections 20. When the zipper tape 10 passes through the guide wheels 21, the guide wheels 21 rotate along the guide sections 20. By setting the guide wheels 21, the friction between the zipper and the guide sections 20 is reduced.

[0041] The support rod 1 is provided with a mounting bracket 22 at its bottom. The mounting bracket 22 is installed at the zipper outlet of the zipper machine, and the detection device is installed on the zipper machine through the mounting bracket 22.

[0042] In this invention, a first positioning groove 23 is provided at the connection between the mounting bracket 22 and the support rod 1, and a second positioning groove 25 is provided at the connection between the fixing seat 12 and the support rod 1. The stability of the connection is increased by providing the first positioning groove 23 and the second positioning groove 25.

[0043] In this utility model, a traction device (not shown in the attached drawings) is set on one side of the guide chain shaft 2 to traction the zipper belt 10. The traction device and the connection between the traction device and the zipper belt 10 are existing technologies and will not be specifically described in this utility model. The two zipper belts 10 pass through the guide chain wheel 21 in sequence along the traction direction, then are introduced into the toothed zipper head 8, then into the arched zipper head 7, and finally exit through the guide chain groove 9. It should be noted that if the zipper belt 10 teeth are arched, it will pass smoothly when it passes through the toothed zipper head 8 (that is, the toothed zipper head 8 fails to detect the arched zipper belt 10). Therefore, an additional arched zipper head 7 is needed to avoid missed detection.

[0044] When the zipper belt 10 is pulled, it is taut. The detection platform 3 compresses the spring 14. When no missing teeth or arching is detected, the sensing block 16 moves away from the proximity switch 15. When a zipper belt 10 with missing teeth passes the pressure-deficient zipper head, the zipper belt 10 moves the detection platform 3 to continue compressing the spring 14, causing the sensing block 16 to approach the proximity switch 15. The proximity switch 15 sends a signal to the control device to stop the traction device and remind the staff to check and mark it. When an arched zipper belt 10 passes the arched zipper head 7, the zipper belt 10 moves the detection platform 3 to continue compressing the spring 14, causing the sensing block 16 to approach the proximity switch 15. The proximity switch 15 sends a signal to the control device to stop the traction device and remind the staff to check and mark it.
