Description

Technical Field

[0001] This invention relates to the field of handbag zipper testing technology, and more particularly to a handbag zipper quality testing device. Background Technology

[0002] Zippers are connectors that use continuously arranged teeth to join or separate items, and are widely used in clothing, bags, tents, etc. A missing tooth refers to a defective zipper, specifically the absence of a single tooth in a continuous zipper chain. In the production of rectangular handbags, the zipper is first sewn onto a rectangular piece of fabric. To ensure easy access to items inside the bag, the zipper is typically positioned in a U-shape on the rectangular fabric. Then, samples of the same batch of zippered rectangular fabric are randomly selected for inspection. After inspection, this batch of zippered rectangular fabric is then sewn into a rectangular shape.

[0003] Existing technologies generally use visual inspection devices to detect missing teeth in zippers. However, this method requires the zipper and the visual inspection device to be aligned to effectively complete the inspection of the zipper. Therefore, workers need to frequently adjust the position and state of the zipper to adapt to the visual inspection device. This is not only too cumbersome to operate, but also has a low detection accuracy.

[0004] Furthermore, existing zipper detection devices only have a single function, and when detecting multiple data points, it is necessary to switch between multiple devices or scenarios, making the detection process complex. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, which require frequent manual adjustments to the position and state of zippers to adapt to visual inspection devices, resulting in cumbersome operation and low detection accuracy, this invention provides a zipper quality inspection device for handbags.

[0006] The technical solution is as follows: A zipper quality inspection device for handbags, comprising an installation plate, a winding component, a drive assembly, an air supply assembly, and an installation frame; the installation plate is equipped with two winding components distributed left and right; the winding components are provided with clamping parts; the installation plate is equipped with a drive assembly; the drive assembly is equipped with an installation frame; the installation frame is equipped with an air supply assembly; it also includes a liquid storage frame, a grid, air bladders, and a ventilation plate; the drive assembly is equipped with a liquid storage frame, which is located below the installation frame; the lower part of the liquid storage frame is provided with several liquid inlets; the upper part of the liquid storage frame is fixedly connected with a grid; the grid is provided with several squares; the lower part of the installation frame is provided with several air bladders, and the air bladders are generally rectangular; each air bladder at the edge of the rectangular structure is provided with a ventilation plate; the ventilation plate is provided with several ventilation slots; the drive assembly is used to drive the installation frame, liquid storage frame, grid, air bladders, and ventilation plate to move vertically; the air supply assembly is used to supply gas to the air bladders and ventilation plates.

[0007] As an improvement to the above solution, the grille is made of a transparent material.

[0008] As an improvement to the above scheme, it also includes liquid baffles; each square of the grid is provided with two liquid baffles, and the lower surface of the liquid baffles is flush with the vertical midpoint of the square, and the space between the two liquid baffles is set as a ventilation zone.

[0009] As an improvement to the above scheme, the two liquid separators in the same square are arranged in parallel at the bottom and have an upward-opening "V"-shaped structure at the top.

[0010] As an improvement to the above solution, each airbag is equipped with an air valve.

[0011] As an improvement to the above solution, the liquid stored in the reservoir and grid is corrosive.

[0012] As an improvement to the above solution, the liquid stored in the reservoir and grid contains fine particles.

[0013] As an improvement to the above scheme, several air nozzles are provided on the outer side of the grille.

[0014] As an improvement to the above solution, several grinding strips are provided at the bottom of the vent plate.

[0015] As an improvement to the above solution, several protrusions are provided at the lower part of the airbag.

[0016] Beneficial Effects: This invention sprays gas from the ventilation slots on the ventilation plate onto the zipper section. When there is a missing tooth in the zipper section, the gas quickly passes through the missing tooth and reaches the grid squares. The impact of the gas causes liquid to splash in the grid squares. The more liquid splashes, the more severe the missing tooth problem. Conversely, if no liquid splashes, it means that there is no missing tooth in that part of the zipper section. In this way, the missing tooth data of the zipper section in that square can be obtained based on the liquid splashing state. Thus, with simple operation, the missing tooth situation of each part of the zipper section can be accurately detected. This solves the problems of the prior art, which uses a visual inspection device to detect missing teeth in zippers. The zipper and the visual inspection device must be kept in perfect alignment to effectively complete the zipper inspection. The zipper's state also needs to be frequently adjusted to adapt to the visual inspection equipment, which is cumbersome and has a low detection accuracy.

[0017] This invention utilizes the upward-opening "V"-shaped structure of the liquid separator plates. As gas passes through the two liquid separator plates from top to bottom, the "V"-shaped structure increases the gas flow rate. Furthermore, the narrow parallel structure accelerates the gas flow speed, resulting in a more significant impact reaction between the gas and the liquid in the storage box after passing through the two liquid separator plates, allowing the liquid to splash up at a faster speed.

[0018] When the liquid in the square is splashed, it comes into contact with the lower surface of the zipper. The corrosive liquid corrodes the zipper, accelerating its corrosion and aging. After the rectangular fabric is removed, the pull tab on the zipper is pulled to observe whether it works properly, thus testing the corrosion resistance and durability of the zipper. This solves the problem that existing zipper testing devices only have a single function and require switching between multiple devices or scenarios to test multiple data points, making the testing process complex.

[0030] Example 1

[0031] A quality inspection device for handbag zippers, such as Figures 1-9 As shown, the device includes a mounting plate 1, a winding component 2, a drive assembly, an air supply assembly, and a mounting frame 3. The mounting plate 1 is bolted to two left-right distributed winding components 2, which are used to wind up the left and right ends of the handbag 001. Each winding component 2 is provided with a clamping part 2a, which is used to clamp the handbag 001 when it is being wound up. The mounting plate 1 is equipped with the drive assembly. The drive assembly is equipped with the mounting frame 3. The mounting frame 3 is equipped with the air supply assembly.

[0032] It also includes a liquid storage frame 4, a grille 5, airbags 6, and a vent plate 7; the drive assembly is equipped with the liquid storage frame 4, which is located below the mounting frame 3; the lower surface of the liquid storage frame 4 is provided with several liquid inlets 4a, through which liquid is injected into the liquid storage frame 4; a grille 5 is fixedly connected to the upper part of the liquid storage frame 4; the grille 5 is provided with several squares 100; the lower surface of the mounting frame 3 is provided with several airbags 6, and the airbags 6 are generally rectangular in structure; each is in a rectangular structure Each of the airbags 6 at the edge is provided with a vent plate 7 at its lower part, and all the vent plates 7 together form a rectangular frame structure. The vent plates 7 are located above the grid 5 and are directly opposite the squares 100 of the grid 5. Several venting grooves are provided on the lower surface of the vent plates 7. Gas is sprayed through the vent plates 7 into the zipper section 001a, so that the gas passes through the zipper section 001a and reaches the grid 5. The liquid state in the grid 5 is observed to detect the missing teeth phenomenon of the zipper section 001a.

[0033] The grid 5 is made of transparent material, so the liquid state in the grid 5 and the liquid storage box 4 can be observed with the naked eye.

[0034] The drive assembly includes a first electric actuator 101, a first connecting plate 102, a second electric actuator 103, and a second connecting plate 104. The mounting plate 1 has four first electric actuators 101 arranged in a rectangular pattern. The telescopic portions of the two front first electric actuators 101 are jointly fixed to a first connecting plate 102, and the telescopic portions of the two rear first electric actuators 101 are jointly fixed to another first connecting plate 102. The two first connecting plates 102 are jointly fixed to the mounting frame 3. Four second electric actuators 103 arranged in a rectangular pattern are mounted on the lower part of the mounting plate 1. The two left second electric actuators 103 are jointly fixed to a second connecting plate 104, and the two right second electric actuators 103 are jointly fixed to another second connecting plate 104. The two second connecting plates 104 are jointly fixed to the liquid storage frame 4.

[0035] The air supply assembly includes a pipe rack 111, a first branch pipe 112, and a second branch pipe 113; the pipe rack 111 is mounted on the mounting frame 3; the pipe rack 111 is provided with a plurality of air inlets 111a, and a pump is connected to the air inlets 111a; the pipe rack 111 is provided with a plurality of first branch pipes 112, and the first branch pipes 112 pass through the mounting frame 3 and are connected to the airbag 6; the pipe rack 111 is provided with a plurality of second branch pipes 113, and the second branch pipes 113 pass through the mounting frame 3 and are connected to the ventilation plate 7.

[0036] The tooth-missing detection process of the zipper part 001a of the present invention is as follows:

[0037] Before testing, control the telescopic part of the first electric push rod 101 to drive the first connecting plate 102, mounting frame 3, air supply component, airbag 6 and ventilation plate 7 to move upward, leaving enough space for the placement of the rectangular fabric.

[0038] At this point, the rectangular fabric with the zipper section 001a sewn on is placed on the mounting plate 1 with the zipper section 001a taut, so that the pull side of the zipper section 001a is facing upwards, and the rectangular fabric is located below the ventilation plate 7. Then, the clamping parts 2a on the left and right winding parts 2 are controlled to clamp the left and right ends of the fabric respectively, and the left and right winding parts 2 are used to wind up the left and right ends of the rectangular fabric respectively, so that the rectangular fabric is taut, thereby clamping and fixing the rectangular fabric to prevent it from being skewed during the inspection process.

[0039] Subsequently, the telescopic part of the second electric push rod 103 is controlled to drive the second connecting plate 104, the liquid storage frame 4 and the grid 5 to move upward, so that the upper surface of the grid 5 is in close contact with the lower surface of the zipper part 001a on the rectangular fabric, so that the U-shaped zipper part 001a is located within the square 100 of the grid 5. Then, the telescopic part of the first electric push rod 101 is controlled to drive the first connecting plate 102, the mounting frame 3, the air supply component, the airbag 6 and the ventilation plate 7 to move downward, so that the lower surface of the ventilation plate 7 is in close contact with the upper surface of the zipper part 001a on the rectangular fabric, so that the U-shaped zipper part 001a is located within the range of the ventilation plate 7. At this time, the rectangular material is located between the upper surface of the grid 5 and the lower surface of the ventilation plate 7, and the upper surface of the grid 5 and the lower surface of the ventilation plate 7 are in contact with the rectangular fabric, and the zipper part 001a is divided into several detection areas by the square 100 on the grid 5.

[0040] At this point, the inspection of the zipper section 001a on the rectangular fabric can begin; control the external pump to inject gas into the airbag 6 through the air inlet 111a, the pipe rack 111, and the first branch pipe 112 in sequence, so that the airbag 6 expands rapidly. During the expansion of the airbag 6, the ventilation plate 7 is continuously pressed down, so that the ventilation plate 7 presses the zipper section 001a of the rectangular fabric onto the grid 5. At the same time, the airbag 6 continues to expand towards the side of the ventilation plate 7 in a wrapped state to prevent the subsequent leakage of gas sprayed from the ventilation plate 7.

[0041] Subsequently, the external injection device injects liquid into the storage frame 4 through the inlet 4a, causing the liquid to slowly overflow into the squares 100 of the grid 5 until it reaches half the height of the squares 100. Then, gas is injected into the vent plate 7 through the second branch pipe 113, causing the gas to spray from the vent grooves on the vent plate 7 towards the zipper section 001a. When there is a missing tooth in the zipper section 001a, the gas will quickly pass through the missing tooth and reach the squares 100 of the grid 5. The impact of the gas causes liquid to splash up in the squares 100 of the grid 5. The more liquid splashes up, the more severe the missing tooth problem; conversely, the less liquid splashes up, the more severe the problem. If no liquid splashes, it means that there is no missing tooth in that part of the zipper 001a. Thus, the missing tooth data of the zipper 001a in that square 100 can be obtained based on the state of liquid splashing. In this way, the missing tooth situation of each part of the zipper 001a can be accurately detected through simple operation. This solves the problem in the prior art that when using a visual inspection device to detect missing teeth in zippers, the zipper and the visual inspection device need to be kept in the same position to effectively complete the zipper inspection work. It also requires frequent adjustment of the zipper to adapt to the visual inspection equipment, which is cumbersome and has a low detection accuracy.

[0042] After the missing tooth detection of zipper part 001a is completed, the external pump is first controlled to extract the liquid from the storage frame 4 and grid 5 through the liquid inlet 4a for use in the next detection, reducing resource waste; then the drive assembly is controlled to move the mounting frame 3, airbag 6 and ventilation plate 7 upward, and at the same time, the drive assembly is controlled to move the storage frame 4 and grid 5 downward, so that the rectangular fabric that has been detected can be taken out smoothly.

[0043] It also includes liquid-separating plates 8; each square 100 of the grid 5 is provided with two liquid-separating plates 8, and the lower surface of the liquid-separating plate 8 is flush with the vertical midpoint of the square 100, and the space between the two liquid-separating plates 8 is set as a ventilation area 200; when detecting the missing tooth phenomenon of the zipper part 001a, the zipper part 001a is placed within the ventilation area 200, and the gas sprayed from the ventilation groove on the ventilation plate 7 to the zipper part 001a will directly pass through the narrow ventilation area 200 and impact the liquid in the square 100, so that the liquid in the square 100 surges from the middle towards the two liquid-separating plates 8, reducing the contact area between the gas and the liquid, so that the liquid can splash up at a faster speed and shorten the detection time.

[0044] The two liquid-separating plates 8 in the same square 100 are arranged in parallel at the bottom and have an upward-opening "V" shape at the top. Due to the upward-opening "V" shape of the liquid-separating plates 8, when the gas passes through the two liquid-separating plates 8 from top to bottom, the "V" shape increases the gas flow rate. Then, through the narrow parallel structure, the gas flow speed is accelerated, so that after the gas passes through the two liquid-separating plates 8, there is a more obvious impact reaction with the liquid in the liquid storage frame 4, which allows the liquid to splash up at a faster speed.

[0045] A rubber strip is provided on the upper surface of the liquid separator 8 to increase the fit between the liquid separator 8 and the zipper part 001a, thereby improving the sealing between the zipper part 001a and the liquid separator 8 and preventing gas from escaping from the edge of the liquid separator 8, thus increasing the detection accuracy.

[0046] Each airbag 6 is equipped with an air valve; the expansion or contraction of the airbag 6 can be controlled individually through the air valve of the airbag 6; after the missing tooth detection of the zipper part 001a is completed, the control drive component drives the liquid storage frame 4 and the grid 5 to move downward, leaving space for the downward compression of the rectangular fabric. Subsequently, the airbag 6 located in the middle area is controlled to expand downward through the first branch pipe 112, squeezing the middle of the rectangular fabric, simulating the situation when the handbag 001 is squeezed in daily use, to test whether the zipper will break, thereby testing the stability of the connection between the zipper teeth.

[0047] The clamping surface of the clamping part 2a is provided with anti-slip texture to increase the friction between the clamping surface of the clamping part 2a and the rectangular fabric, thereby increasing the clamping force of the clamping part 2a on the rectangular fabric.

[0048] Example 2

[0049] Based on Example 1, the liquid stored in the storage box 4 and the grid 5 is corrosive. When the liquid in the grid 100 is splashed, it will come into contact with the lower surface of the zipper part 001a. The corrosive liquid will corrode the zipper part 001a, accelerating the corrosion and aging of the zipper part 001a. After the rectangular fabric is removed, the puller on the zipper part 001a is pulled to observe whether the puller can work normally, so as to detect the corrosion resistance and durability of the zipper part 001a. This solves the problem that existing zipper detection devices only have a single function and require switching between multiple devices or scenarios when detecting multiple data, making the detection process complicated.

[0050] The liquid stored in the liquid storage box 4 and the grid 5 contains fine particles. When the liquid in the grid 100 is splashed and comes into contact with the lower surface of the zipper part 001a, the fine particles in the liquid adhere to the surface of the zipper part 001a. After the rectangular fabric is removed, the puller on the zipper part 001a is pulled to observe whether the puller can work normally, so as to test whether the zipper part 001a can work normally in the presence of fine particles, and to test the applicability of the zipper part 001a.

[0051] Several air nozzles 201 are provided on the outer side of the grille 5; when the rectangular fabric contaminated with corrosive liquid is taken out, the air nozzles 201 are controlled to blow air upwards, and the air is used to dry the corrosive liquid on the lower surface of the zipper part 001a that has not penetrated, so as to prevent the corrosive liquid from dripping everywhere after the rectangular fabric contaminated with corrosive liquid is taken out, which would seriously affect the working environment.

[0052] Example 3

[0053] Based on embodiment 2, a plurality of polishing strips are provided on the lower surface of the vent plate 7; the upper surface of the zipper part 001a is rubbed by the polishing strips.

[0054] The wear detection process for the zipper section 001a of this invention is as follows:

[0055] After completing the tooth-missing test of the zipper section 001a, before removing the rectangular fabric, the left winding component 2 is controlled to release the left end of the rectangular fabric, while the right winding component 2 is controlled to wind up the right end of the rectangular fabric, causing the rectangular fabric to move from left to right. Then, the left winding component 2 is controlled to wind up the left end of the rectangular fabric again, while the right winding component 2 is controlled to release the right end of the rectangular fabric, causing the rectangular fabric to move from right to left. This process is repeated, causing the rectangular fabric to move repeatedly in the left and right directions, so that the upper surface of the zipper section 001a on the rectangular fabric rubs against the abrasion strip set on the lower surface of the ventilation plate 7, simulating the scenario of the handbag 001 being rubbed by hard objects during daily use, in order to test the abrasion resistance of the zipper section 001a.

[0056] The lower surface of the airbag 6 is provided with several raised strips; during the process of the rectangular fabric moving repeatedly in the left and right directions, the raised strips on the lower surface of the airbag 6 continuously squeeze the rectangular fabric and the zipper part 001a on it, simulating the scenario of the handbag 001 being pressed by a sharp object during daily use, in order to test the squeezing force that the zipper part 001a can withstand.

Therefore, the scope of this disclosure should not be limited to the above embodiments, but should be defined not only by the appended claims, but also by their equivalents.
