Description

Technical Field

[0001] This utility model relates to the technical field of zipper polishing equipment, and in particular to an automatic polishing equipment for continuous polishing of plastic zippers. Background Technology

[0002] Zippers are connectors that use continuously arranged teeth to join or separate items, and they are ubiquitous in daily life. Polishing machines are one of the important pieces of equipment in the zipper production process. Existing zipper polishing devices mainly polish metal zippers by using an ultrasonic device in an electrolytic degreasing chamber and a DC power supply connected to the electrolytic degreasing chamber and the electrolytic polishing chamber. However, common zippers also include plastic zippers. Plastic zippers are widely used because they are lightweight, elastic, water-resistant, corrosion-resistant, and low-cost. However, plastic zippers are produced by continuous injection molding, and after injection molding, burrs, flash, injection gate protrusions, and other defects inevitably form on the zipper teeth, affecting their appearance and use, and may also scratch clothing or skin. Existing metal zipper polishing devices are not suitable for plastic zippers.

[0003] According to the utility model patent with publication number CN216940036U, entitled "A Polishing Device for Plastic Zipper Teeth", there is now a polishing device specifically for plastic zippers. It is equipped with a conveyor belt channel and a polishing wheel is set at the tangent position of the conveyor belt channel. When the zippers on both sides pass through the conveyor belt channel, the rotating polishing wheel polishes the end face of the rubber teeth to remove burrs and flash from the zipper.

[0004] Zipper chains have corners between their front / back sides and end faces. However, existing polishing devices have relatively fixed polishing wheel positions and cannot polish these corners. They can only polish the end faces of the zipper teeth. In addition, since plastic zippers are injection molded, glue residue is inevitable, which will form glue spots on the zipper end face. These glue spots are too hard and ordinary polishing wheels cannot polish them smoothly. Furthermore, in the industry, to facilitate continuous zipper production, strip studs or knots are generally used to connect multiple zipper tapes of the same specification. However, these zipper connection structures can cause jamming when passing through the tape exit device after polishing. Therefore, most existing polishing devices can only be used for single zippers. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic polishing device for continuous polishing of plastic zippers, comprising a vertical polishing mechanism, a horizontal polishing mechanism, a chain engaging mechanism, and a chain discharging mechanism arranged from front to back. The vertical polishing mechanism includes a cutting wheel arranged from top to bottom, and at least two a polishing wheels and b polishing wheels. Single-row positioning clamps are symmetrically arranged on both sides of the cutting wheel, a polishing wheel, and b polishing wheels. Several a polishing wheels are inclined upwards, and several b polishing wheels are inclined downwards. The horizontal polishing mechanism includes several c polishing wheels arranged in a row. Double-row positioning clamps are arranged directly above several c polishing wheels. The chain engaging mechanism is detachably provided with a chain head for engaging the zipper teeth. The chain discharging mechanism includes a lower discharging wheel, a pressure wheel, and a discharging motor. The output end of the discharging motor is connected to the lower discharging wheel. The pressure wheel is located on the top of the lower discharging wheel and is held tightly against the lower discharging wheel by an elastic element.

[0007] Furthermore, it includes a worktable, on which the vertical polishing mechanism, horizontal polishing mechanism, chain closing mechanism and chain exit mechanism are arranged from front to back to form an L-shaped zipper chain passage route. A guide rod is provided on the worktable between the vertical polishing mechanism and the horizontal polishing mechanism.

[0008] Furthermore, the vertical polishing mechanism includes a housing and several first drive motors, the several first drive motors being respectively connected to the cutting wheel, polishing wheel a and polishing wheel b, and several single-row positioning clamps being movably disposed in the housing.

[0009] Furthermore, there are two polishing wheels, a and b, with the two polishing wheels a rotating in opposite directions and the two polishing wheels b rotating in opposite directions.

[0010] Furthermore, the chassis is equipped with a horizontal guide rail and a first micrometer. The single-row positioning clamp is detachably provided with a first slider that is slidably connected to the horizontal guide rail. The first micrometer is elastically connected to the first slider by a tension spring, and the telescopic end of the first micrometer abuts against the first slider.

[0011] Furthermore, the outer side of the cutting wheel is provided with cutting protrusions arranged in a ring.

[0012] Furthermore, the horizontal polishing mechanism includes a fixed frame, a movable frame, and several second drive motors. The movable frame slides left and right on the fixed frame in the feeding direction. The c-polishing wheels are arranged on one side of the movable frame, and the second drive motors are arranged on the other side. The c-polishing wheels and the second drive motors are connected in a one-to-one correspondence. The double-row positioning clamps are movably arranged on the fixed frame.

[0013] Furthermore, the fixed frame is equipped with a vertical guide rail and a second micrometer. The double-row positioning clamp is detachably provided with a second slider that is slidably connected to the vertical guide rail. The second micrometer is elastically connected to the second slider by a tension spring, and the telescopic end of the second micrometer abuts against the second slider.

[0014] Furthermore, both the single-row positioning clip and the double-row positioning clip are provided with a through chain channel, and one side is provided with an arc-shaped notch connected to the chain channel for the zipper teeth passing through the chain channel to be exposed.

[0015] Furthermore, the outer side of the lower belt pulley is provided with knurled texture, and the pressure pulley includes a gravity wheel core, with a rubber layer provided on the outer side of the gravity wheel core.

[0016] Furthermore, an oiling mechanism is provided between the horizontal polishing mechanism and the chain assembly mechanism.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up a vertical polishing mechanism and a horizontal polishing mechanism, the vertical polishing mechanism includes a cutting wheel arranged from top to bottom, as well as at least two a polishing wheels and b polishing wheels. The cutting wheel is used to cut the adhesive on the zipper teeth. Several a polishing wheels are arranged at an upward inclination, and several b polishing wheels are arranged at a downward inclination. The a polishing wheels and b polishing wheels are used to polish the corners between the front / back sides and the end face of the adhesive teeth, respectively. The horizontal polishing mechanism includes several c polishing wheels arranged in a row. The c polishing wheels are used to polish the end face of the adhesive teeth, thereby achieving multi-directional polishing of the zipper teeth.

[0018] After passing through the vertical and horizontal polishing mechanisms, the zipper chains are joined together by a chain-closing mechanism to form a zipper. The zipper is then output through a chain-exit mechanism located behind the chain-closing mechanism. The chain-exit mechanism is powered by the lower pulley of the chain-exit mechanism. The pressure roller presses against the lower pulley under the action of gravity, and the pressure roller is tightened by the elastic element. After the pressure roller is lifted by the zipper's connecting structure, it quickly returns to its original state, effectively preventing the zipper output from jamming. This achieves fully automated production from polishing to chain closing and chain output, suitable for continuous operation. At the same time, by setting the cutting wheel and at least two polishing wheels (a and b) vertically, the space utilization is improved, making the polishing equipment occupy a small area.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] As shown in the attached figure, this utility model discloses an automatic polishing device for continuous polishing of plastic zippers, comprising a vertical polishing mechanism 1, a horizontal polishing mechanism 2, a zipper engaging mechanism 3, and a zipper discharging mechanism 4 arranged from front to back. The vertical polishing mechanism 1 includes a cutting wheel 11 arranged from top to bottom, and at least two a-polishing wheels 12 and b-polishing wheels 13. Single-row positioning clamps 15 are symmetrically arranged on both sides of the cutting wheel 11, a-polishing wheels 12, and b-polishing wheels 13. Several a-polishing wheels 12 are inclined upwards, and several b-polishing wheels 13 are inclined downwards. The inclination angles of the a-polishing wheels 12 and b-polishing wheels 13 correspond, preferably at 30-45 degrees. The horizontal polishing mechanism 2 includes several c-polishing wheels 14 arranged in a row. Double-row positioning clamps 22 are arranged directly above each c-polishing wheel 14. The zipper engaging mechanism 3 is detachably equipped with a zipper head 31 for engaging the zipper teeth. The chain head 31 is a standard zipper chain head 31. It should be noted that different specifications of zippers require different chain heads 31, so it needs to be designed as a detachable structure to facilitate the replacement of the chain head 31. Specifically, the chain engaging mechanism 3 includes a base 300 and a chain head 31. The base 300 is fixed on the workbench 5, and the chain head 31 can be detachably installed on the base 300. In addition, magnetic connection can be used. By using a metal chain head 31, the base 300 is provided with diamond-shaped or square magnetic blocks to attract the chain head 31. A corresponding groove can also be provided on one side of the chain head 31 to prevent displacement. Alternatively, the chain head 31 can be directly installed on the base 300 with screws to facilitate the replacement of the chain head 31. The chain discharging mechanism 4 includes a lower belt discharging wheel 41, a pressure wheel 42, and a belt discharging motor. The output end of the belt discharging motor is connected to the lower belt discharging wheel 41. The pressure wheel 42 is set on the top of the lower belt discharging wheel 41 and is kept in close contact with the lower belt discharging wheel 41 by an elastic element 43.

[0035] In embodiment one, a vertical polishing mechanism 1 and a horizontal polishing mechanism 2 are provided. The vertical polishing mechanism 1 contains a cutting wheel 11 and at least two a-polishing wheels 12 and b-polishing wheels 13 arranged from top to bottom. The cutting wheel 11 is used to cut the adhesive on the zipper teeth. Several a-polishing wheels 12 are arranged at an upward angle, and several b-polishing wheels 13 are arranged at a downward angle. The a-polishing wheels 12 and b-polishing wheels 13 are used to polish the corners between the front / rear sides and the end face of the zipper teeth, respectively. For example, the a-polishing wheel 12 polishes the corners between the rear side and the end face of the zipper teeth, while the b-polishing wheel 13 polishes the corners. Further explanation regarding the corners between the front and end faces of the polishing chain: the two chain rows are located on both sides of polishing wheel 12 (a) and polishing wheel 13 (b). Therefore, at least two polishing wheels 12 (a) and 13 (b) are provided. By using multiple polishing wheels 12 (a) and 13 (b) with different directions, both chain rows can be polished, ensuring a more balanced polishing. The horizontal polishing mechanism 2 includes several polishing wheels 14 (c) arranged in a row. The polishing wheels 14 polish the end faces of the zipper teeth, achieving multi-directional polishing of the zipper teeth, effectively replacing existing plastic zipper polishing equipment. After the zipper chain passes through the vertical polishing mechanism 1 and the horizontal polishing mechanism 2 to complete the polishing action, the two chain chains are merged into a zipper by the chain closing mechanism 3. Then, the zipper is output by the chain output mechanism 4 located behind the chain closing mechanism 3. The chain output mechanism 4 is powered by the lower belt pulley 41. The pressure roller 42 presses against the lower belt pulley 41 under the action of gravity, and the elastic element 43 pulls the pressure roller 42 tight. After the pressure roller 42 is lifted by the zipper connection structure, it quickly returns to its original state, realizing fully automated production from polishing to chain closing and chain output. It is suitable for continuous operation. At the same time, by setting the cutting wheel 11 and at least two a polishing wheels 12 and b polishing wheels 13 in a vertical position, the space utilization rate is improved, making the polishing equipment occupy a small area.

[0036] The zipper is moved out of the polishing equipment by the cooperation of a pressure roller 42 with a certain weight and the lower pulley 41. Since each individual zipper is connected by a connecting structure such as pins, it is necessary to increase the weight to make the pressure roller 42 press tightly against the lower pulley 41, thereby increasing the friction between the lower pulley 41 and the pressure roller 42. In addition, it should be noted that an elastic element 43 is also used to tighten the pressure roller 42. The elastic element 43 can be a tension spring 104 or a spring. The main purpose is to ensure that the pressure roller 42 remains pressed tightly against the lower pulley 41, preventing the pressure roller 42 from being lifted by the zipper's connecting structure, which would prevent the zipper from moving out normally. On this basis, the lower pulley 41 has a knurled texture on its outer side. The pressure roller 42 includes a gravity wheel core, and the outer side of the gravity wheel core is provided with a rubber layer. Both the knurled texture and the rubber layer are used to increase the friction, while the gravity wheel core is a wheel core with a certain weight to ensure that the pressure roller 42 presses tightly against the lower pulley 41.

[0037] Example 2 includes a workbench 5. The vertical polishing mechanism 1, horizontal polishing mechanism 2, chain engaging mechanism 3, and chain disengagement mechanism 4 are arranged from front to back on the workbench 5, forming an L-shaped zipper chain passage route. The vertical polishing structure, with the cutting wheel 11, polishing wheel 12 (a), and polishing wheel 13 arranged vertically, greatly saves the floor space of the polishing equipment. Furthermore, the workbench 5 allows for more concentrated installation of the various mechanisms. The vertical polishing mechanism 1, horizontal polishing mechanism 2, chain engaging mechanism 3, and chain disengagement mechanism 4 are arranged in a straight line on the workbench 5. Further explanation: the workbench 5 has openings corresponding to the vertical polishing mechanism 1 and the horizontal polishing mechanism 2, and exhaust fans are installed within these openings to collect polishing debris. Figures 1-2 To ensure the zipper chain runs smoothly along the L-shaped path, the workbench 5 is equipped with guide rods 51 between the vertical polishing mechanism 1 and the horizontal polishing mechanism 2. These guide rods guide the chain chain as it bends. Multiple guide rods 51 are provided, including horizontal and vertical guide rods. A guide wheel assembly is also included to guide the chain chain into the vertical polishing mechanism 1. The guide wheel assembly is a common structure in the existing zipper industry and will not be described in detail. It should be noted that the guide wheel assembly can be... Figure 1 The sensor is positioned directly above the workbench 5, or it can be positioned on top of the vertical polishing mechanism 1 and away from the horizontal polishing mechanism 2, depending on the specific situation. Further explanation: the chain-closing mechanism 3 includes a proximity sensor 301 located in front of the chain head 31. This sensor detects the zipper connection structure in real time. If a zipper connection structure is detected, the machine stops and an alarm is triggered to alert the operator, helping the zipper connection structure pass smoothly through the chain-closing mechanism. Additionally, sensors are also installed on the vertical polishing mechanism 1 and the chain-exit mechanism 4.

[0038] In embodiment three, the vertical polishing mechanism 1 includes a housing 100 and several first drive motors 101. The several first drive motors 101 are respectively connected to the cutting wheel 11, the a-polishing wheel 12, and the b-polishing wheel 13. Several single-row positioning clamps 15 are movably mounted in the housing 100. The cutting wheel 11, the a-polishing wheel 12, and the b-polishing wheel 13 are all powered by their respective first drive motors 101, enabling independent control and allowing the several a-polishing wheels 12 and the several b-polishing wheels 13 to rotate in either the forward or reverse direction, ensuring better and more even polishing results on both sides of the chain. The single-row positioning clamp 15 is used for single-sided chain walkways, so it needs to be set on both sides of the cutting wheel 11, the a polishing wheel 12 and the b polishing wheel 13. Several of the single-row positioning clamps 15 are movably set on both sides of the chassis 100, so that the single-row positioning clamps 15 corresponding to the cutting wheel 11, the a polishing wheel 12 and the b polishing wheel 13 can be moved away or brought closer, thereby realizing individual or combined use for different functions. For example, if the zipper chain walkway does not need to be cut and glued, the single-row positioning clamps 15 located on both sides of the cutting wheel 11 are moved away from the cutting wheel 11, so that the chain walkway passing through the single-row positioning clamp 15 does not contact the cutting wheel 11. Polishing wheels 12 and 13 are preferably configured as two or in multiples. When there are two polishing wheels 12 and 13, the two polishing wheels 12 rotate in opposite directions, and the two polishing wheels 13 rotate in opposite directions. That is, one polishing wheel 12 / 13 rotates forward, and the other polishing wheel 12 / 13 rotates in reverse. This allows the chain array located on both sides of the polishing wheels 12 / 13 to polish repeatedly from different directions, achieving uniform polishing.A single-row positioning clamp 15 is movably mounted on the chassis 100. Specifically, the chassis 100 has horizontal guide rails 102 and a first micrometer 103 mounted on both sides of the cutting wheel 11, polishing wheel 12, and polishing wheel 13, respectively. The single-row positioning clamp 15 is detachably equipped with a first slider 141 slidably connected to the horizontal guide rails 102. The first micrometer 103 is elastically connected to the first slider 141 via a tension spring 104, and the telescopic end of the first micrometer 103 abuts against the first slider 141. The fixed end of the first micrometer 103 is mounted on the chassis 100. The single-row positioning clamp 15 can be directly connected to the first slider 141 via screws, or it can be connected via another detachable structure. When replacing the single-row positioning clip 15, the connection between the single-row positioning clip 15 and the first slider 141 can be disassembled and replaced separately. The first slider 141 still exists on the housing 100, so it does not need to be completely removed, saving time. To further explain, the form of the tension spring 104 can refer to the existing structure. Both ends of the tension spring 104 are hook-shaped. A protruding ridge is provided on the first slider 141 for the tension spring 104 to hook, which facilitates disassembly and connection. By turning the first micrometer 103, the telescopic end is extended, thereby pushing out the single-row positioning clip 15. Turning the first micrometer 103 causes the telescopic end to retract, and the single-row positioning clip 15 loses the contact of the telescopic end and retracts backward under the action of the tension spring 104. The cutting wheel 11 has cutting protrusions 111 distributed in a ring on its outer side. There is a gap between adjacent cutting protrusions 111. The edges and corners of the cutting protrusions 111 have sharp parts for cutting the adhesive. Under the drive of the first drive motor 101, the cutting wheel 11 rotates continuously and cuts the adhesive protruding from the end face of the chain through the cutting protrusions 111.

[0039] The horizontal polishing mechanism 2 includes a fixed frame 201, a movable frame 202, and several second drive motors 203. The movable frame 202 slides left and right on the fixed frame 201 in the feeding direction. Specifically, a moving track 500 is provided on the worktable 5, and a movable slider 222 is provided at the bottom of the movable frame 202 and slidably connected to the moving track 500. The worktable 5 is provided with a moving motor to drive the movable frame 202 to move back and forth along the moving track 500, so that the polishing wheels 14 on the movable frame 202 and the second drive motors 203 can move back and forth. The machine 203 can move back and forth. The polishing wheels 14 are arranged on one side of the moving frame 202, and the second drive motors 203 are arranged on the other side. The polishing wheels 14 and the second drive motors 203 are connected one-to-one. The double-row positioning clamps 22 are movably mounted on the fixed frame 201. Each polishing wheel 14 is driven by a corresponding second drive motor 203, which can achieve independent control and realize the forward or reverse rotation of several polishing wheels 14. The polishing wheels 14 can be set to two or multiple, preferably as follows: Figure 8The setup shown has four c-polishing wheels 14. The first two c-polishing wheels 14 and the last two c-polishing wheels 14 rotate in the forward and reverse directions, respectively. At the same time, the two c-polishing wheels 14 rotating in the forward and reverse directions can use polishing wheels of different densities to achieve coarse polishing and fine polishing, respectively. It should also be noted that several c-polishing wheels 14 are all set on the moving frame 202. While the c-polishing wheels 14 are polishing the chain in the longitudinal direction, the moving frame 202 drives the c-polishing wheels 14 to move back and forth in the lateral direction, increasing the polishing area of ​​the c-polishing wheels 14. It is not limited to polishing the chain in a single position, which can weaken the polishing texture and thus improve the polishing effect. The specific structure of the double-row positioning clip 22 movably mounted on the fixed frame 201 is as follows: A vertical guide rail 211 and a second micrometer 212 are mounted on the fixed frame 201. The double-row positioning clip 22 is detachably provided with a second slider 221 slidably connected to the vertical guide rail 211. The double-row positioning clip 22 can be directly connected by screws or through another detachable structure for easy replacement. The tension spring 104 can refer to existing structures; both ends of the tension spring 104 are hook-shaped. A protruding ridge is provided on the second slider 221 for the tension spring 104 to hook onto, facilitating disassembly and connection. The second micrometer 212 is elastically connected to the second slider 221 through the tension spring 104, and the telescopic end of the second micrometer 212 abuts against the second slider 221. The tension spring 104… One end is connected to the fixed frame 201, and the other end is connected to the second slider 221. The connection between the vertical guide rail 211 and the second slider 221 ensures that the double-row positioning clamp 22 will not detach from the fixed frame 201. The second micrometer 212 is fixed to the top of the fixed frame 201. When the second micrometer 212 is turned so that its telescopic end extends downward, the telescopic end abuts against the second slider 221, thereby pushing the double-row positioning clamp 22 downward into the c polishing wheel 14. When the second micrometer 212 is turned in the opposite direction so that the telescopic end retracts, the double-row positioning clamp 22 loses the thrust of the telescopic end and moves upward under the action of the tension spring 104. The purpose of setting the first micrometer 103 and the second micrometer 212 also includes adjusting the contact depth between the chain and each polishing wheel or cutting wheel 11, and it can also be applied to chain chains of different specifications.

[0040] It should be noted that both the single-row positioning clamp 15 and the double-row positioning clamp 22 are provided with a through chain track channel 2200, and one side is provided with an arc-shaped notch 2210 connected to the chain track channel 2200, for exposing the zipper teeth passing through the chain track channel 2200. Both the single-row positioning clamp 15 and the double-row positioning clamp 22 are composed of clamping plates 2000. The outer side of the clamping plate 2000 is provided with a groove. When the clamping plates 2000 are spliced ​​together, the corresponding grooves combine to form a chain track channel 22 through which the chain can pass. 00, which allows the chain to pass through stably, and also provides an arc-shaped notch 2210. The arc-shaped notches 2210 on different single-row positioning clamps 15 correspond to the cutting wheel 11, a polishing wheel 12, and b polishing wheel 13 respectively. The arc-shaped notches 2210 on the double-row positioning clamp 22 correspond to the c polishing wheel 14. The single-row positioning clamp 15 has two clamping plates 2000, and the double-row positioning clamp 22 has three clamping plates 2000. That is, the double-row positioning clamp 22 is formed by the combination of three clamping plates 2000 to form two chain channel 2200.

[0041] It should be noted that an oiling mechanism 6 is provided between the horizontal polishing mechanism 2 and the chain assembly mechanism 3. That is, the vertical polishing mechanism 1, the horizontal polishing mechanism 2, the oiling mechanism 6, the chain assembly mechanism 3 and the chain output mechanism 4 are arranged from front to back on the worktable 5. The oiling mechanism 6 includes an oil box and a double-row positioning clamp 22. Lubricating oil is added to the double-row positioning clamp 22 to make the chain assembly smoother. The oil box is used to collect the dripping lubricating oil, and can refer to the existing lubricating oil addition structure.

[0042] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
