Description

Technical Field

[0001] This utility model relates to the field of zipper detection technology, specifically to a detection device for zippers with teeth. Background Technology

[0002] A zipper belt consists of two belts, each with a row of metal or plastic teeth, used to connect the edges of an opening (such as the opening of clothing or a bag). A sliding element pulls the two rows of teeth into an interlocking position to close the opening. It is used to sew onto clothing, pockets, or bags, and is also called a zipper. During the production process of a zipper, the arrangement of its meshing teeth needs to be checked to prevent missing teeth from affecting the meshing effect. Therefore, a missing tooth detection device is required.

[0003] In the prior art, a zipper tape missing tooth detection device with the publication number "CN 222964873 U" includes a worktable; it also includes a limiting groove, a support plate, a drive plate, a first spring, a detection block, and a support strip. The limiting groove is opened in the middle of the top of the worktable. Two support plates are symmetrically arranged on the left and right sides of the top of the limiting groove. The drive plate is arranged above the worktable corresponding to the position of the limiting groove. Thirty first springs are arranged at equal intervals on the bottom front side of the drive plate. The detection block is arranged at the bottom end of the first spring. In this invention, the first spring pushes the detection block to move downward until the bottom of the detection block is in contact with the surface of the meshing teeth. When there is a missing tooth in the zipper, the first spring pushes the detection block to press against the surface of the zipper tape. At the same time, the detection block drives the marker strip with adsorbed pigment to be in contact with the surface of the tape through the support strip, thereby leaving a mark on the surface of the tape, making it easy to find the missing tooth.

[0004] In the aforementioned patent, the marking strip is made of sponge material that absorbs pigment. However, the pigment in the sponge may easily dry out or be depleted, which can lead to unclear markings after prolonged use, requiring frequent refilling and affecting continuous detection efficiency. Utility Model Content

[0005] To address the shortcomings of the existing technology, this invention proposes a detection device for zipper teeth.

[0006] To achieve the above-mentioned technical effects, the present invention adopts the following solution:

[0007] A device for detecting teeth on a zipper, comprising:

[0008] The worktable has a limiting groove extending through its length at its upper end.

[0009] A zipper fixing component is provided in the limiting groove to fix the zipper in the limiting groove;

[0010] The detection assembly is mounted on the upper end of the worktable via a lifting mechanism. It includes a lifting plate corresponding to the limiting groove. Several detection blocks are linearly and closely distributed below the lifting plate along its length. The upper end of each detection block is connected to the lower end of the lifting plate via a first spring.

[0011] The marking assembly includes a support rod horizontally connected to one side of the detection block. The length direction of the support rod is perpendicular to the length direction of the zipper tape. A water-absorbing marking strip is fixedly provided at the lower end of the support rod. The lifting mechanism is also provided with a pigment box. The bottom of the pigment box is connected to a number of marking strips through a number of capillary tubes.

[0012] In a preferred embodiment, the support rod is made of porous ceramic material and has an inner cavity. One end of the capillary tube is connected to the bottom of the paint box, and the other end of the capillary tube passes through the lifting plate and communicates with the inner cavity of the support rod.

[0013] In a preferred embodiment, a first guide rod is fixedly connected to the upper end of the detection block, and the lifting plate has a guide hole for the first guide rod to pass through. After the upper end of the first guide rod passes through the guide hole, a limiting head is fixedly provided, and the size of the limiting head is larger than the size of the guide hole.

[0014] In a preferred embodiment, the zipper fixing assembly includes a fixing plate fixedly disposed within a limiting groove, and the lower end of the fixing plate is connected to a pressure plate pressed against the bottom of the limiting groove via a second spring.

[0015] In a preferred embodiment, the lifting mechanism includes a mounting plate fixed above the workbench via a column, a cylinder mounted on the mounting plate, the telescopic rod of the cylinder being fixedly connected downwards to the lifting plate, a second guide rod fixedly mounted at the upper end of the lifting plate, and a guide sleeve cooperating with the second guide rod on the mounting plate.

[0016] Compared with existing technologies, the beneficial effects are:

[0017] This invention has a simple structure and is easy to use. It supplies water-based pigment to the marking strip through a pigment box, thereby maintaining the fullness of the pigment in the marking strip and avoiding the pigment reduction that would cause the marking to become unclear after multiple uses. Furthermore, the continuous supply of pigment avoids frequent refills and improves work efficiency. Attached Figure Description

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] A device for detecting teeth on zippers includes: a worktable 10, a zipper fixing assembly 20, a detection assembly 30, and a marking assembly 40.

[0023] The workbench 10 has a limiting groove 101 extending through its upper end along the length direction. The zipper tape to be tested is inserted into the limiting groove 101 from one end.

[0024] The zipper fixing component 20 is located in the limiting groove 101 and is used to fix the zipper in the limiting groove 101. The zipper fixing component 20 mainly fixes the two ends of the zipper tape.

[0025] The detection component 30 is mounted on the upper end of the workbench 10 via the lifting mechanism 50. It includes a lifting plate 301 corresponding to the limiting groove 101. Several detection blocks 302 are linearly and closely distributed below the lifting plate 301 along its length direction. These blocks are used to detect whether there are missing teeth on the zipper tape. The upper end of the detection block 302 is connected to the lower end of the lifting plate 301 via a first spring 303.

[0026] The marking component 40 includes a support rod 401 horizontally connected to one side of the detection block 302. The length direction of the support rod 401 is perpendicular to the length direction of the zipper tape. A water-absorbing marking strip 402 is fixedly provided at the lower end of the support rod 401. The lifting mechanism 50 is also provided with a pigment box 403 containing water-based pigment. The bottom of the pigment box 403 is connected to several marking strips 402 through several capillary tubes 404. The water-based pigment in the pigment box 403 is transported to the marking strips 402 by gravity through the capillary tubes 404, and the marking strips 402 absorb the pigment.

[0027] After the zipper tape is inserted into the limiting groove 101 and secured by the zipper fixing assembly 20, the lifting mechanism 50 drives the detection assembly 30 downward, bringing the detection block 302 close to the top of the zipper tape teeth. If a missing tooth is detected, the detection block 302 continues to move downward, pressing the marking strip 402 onto the zipper tape's braided weave, thus leaving a colored mark near the missing tooth to facilitate locating its position. Since the surface height of the tooth is usually higher than the surface height of the braided weave, the lower end of the marking strip 402 needs to be lower than the lower end of the detection block 302. Water-based pigment is supplied to the marking strip 402 through the pigment box 403 to maintain the fullness of the pigment within the marking strip 402, preventing the pigment from diminishing after repeated use and causing the mark to become indistinct.

[0028] In a preferred embodiment, the support rod 401 is made of porous ceramic material and has an inner cavity 405. One end of the capillary tube 404 is connected to the bottom of the pigment box 403, and the other end of the capillary tube 404 passes through the lifting plate 301 and communicates with the inner cavity 405 of the support rod 401.

[0029] The material has a rich microporous structure, which is connected to capillaries through the inner cavity 405, forming a microporous liquid storage system. This structure can not only store a certain amount of pigment, but also allow the pigment to seep out more evenly onto the marking surface, avoiding too much or too little marking liquid, and making the marking lines clear and regular.

[0030] In a preferred embodiment, a first guide rod 304 is fixedly connected to the upper end of the detection block 302, and the lifting plate 301 has a guide hole for the first guide rod 304 to pass through. After the upper end of the first guide rod 304 passes through the guide hole, a limiting head 305 is fixedly provided, and the size of the limiting head 305 is larger than the size of the guide hole.

[0031] In a preferred embodiment, the zipper fixing assembly 20 includes a fixing plate 201 fixedly disposed in the limiting groove 101, and the lower end of the fixing plate 201 is connected to a pressure plate 203 pressing against the bottom of the limiting groove 101 via a second spring 202.

[0032] The zipper tape passes under the pressure plate 203 and is pressed against the bottom of the limiting groove 101 by the pressure plate 203 under the elastic force of the second spring 202.

[0033] In a preferred embodiment, the lifting mechanism 50 includes a mounting plate 501 fixed above the workbench 10 by a column. A cylinder 502 is mounted on the mounting plate 501. The telescopic rod of the cylinder 502 is fixedly connected to the lifting plate 301 with its extension rod pointing downwards. A second guide rod 503 is fixedly provided at the upper end of the lifting plate 301. A guide sleeve that cooperates with the second guide rod 503 is provided on the mounting plate 501.
