Description

Technical Field

[0001] This invention belongs to the field of zipper production, specifically a zipper surface treatment device and treatment method. Background Technology

[0002] During use, the zipper teeth will repeatedly engage and disengage, and there will be repeated friction between the teeth and between the teeth and the zipper head. In order to improve the durability of the zipper, chemical polishing, electroplating and spraying are used to treat the surface of the formed zipper during the production process.

[0003] In the process of chemical polishing metal zippers, the zipper needs to be immersed in the chemical solution for several minutes. However, since existing zippers are manufactured by evenly fixing the chain teeth onto a fabric strip, during the chemical polishing process, not only the metal chain teeth but also the fabric strip are immersed in the chemical solution. The fabric strip has good moisture absorption, and when the zipper is removed from the chemical solution, the fabric not only carries away the chemical solution but also cannot be quickly removed by rinsing like the residual chemical solution on the surface of the chain teeth. This results in a large consumption of chemical solution, a long cleaning time after polishing, and a large amount of water consumption. To address the above problems, this invention proposes a zipper surface treatment device and treatment method. Summary of the Invention

[0004] The purpose of this invention is to address the problems in the prior art by providing a zipper surface treatment device and method.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A zipper surface treatment device includes a polishing tank for containing and heating polishing liquid, a thermometer for monitoring the temperature of the polishing liquid, a conveying roller for introducing and withdrawing the zipper into the polishing tank, and a plurality of traction rollers for pulling the zipper into the polishing liquid during the transmission process. It also includes a cleaning mechanism for cleaning residual polishing liquid on the zipper tape and a replenishing mechanism for replenishing polishing liquid into the polishing tank.

[0007] The cleaning mechanism includes an inner cylinder, a rotatable mesh cylinder fitted outside the inner cylinder, and a cleaning hood fitted outside the mesh cylinder. The inner cylinder and the cleaning hood are fixed to the polishing tank. The mesh cylinder is used for directional transport of the zipper, and the cleaning hood is used to generate an air curtain and a water curtain. The cleaning hood, together with the mesh cylinder, is used to first control the water flow of the zipper wound on the mesh cylinder and then rinse it with water. The inner cylinder is used to collect the mixed liquid generated during the rinsing of the zipper and transport the mixed liquid into the replenishment mechanism to prepare the polishing liquid.

[0008] As a further optimization of the present invention, the cleaning hood has an arc-shaped structure and is sleeved on top of the mesh cylinder. The cleaning hood has an air chamber and a water chamber inside, and several channels for water and air passage are opened in the side wall of the cleaning hood. The outside of the cleaning hood is provided with pipes for connecting to external water and air sources.

[0009] As a further optimization of the present invention, the mesh cylinder includes several support rings arranged in a linear array and a support mesh provided between two adjacent support rings. The support mesh has a ring structure. Several ring grooves corresponding to the support mesh are opened in the side walls of the conveying roller and the traction roller. The through grooves for water passage and air passage on the cleaning cover correspond to the support mesh.

[0010] As a further optimization of the present invention, an internal gear ring is provided on the end face of the support ring and an active gear for driving the internal gear ring is provided on the end face of the inner cylinder. A water inlet is provided in the side wall of the inner cylinder, which is positioned opposite to the water cavity in the cleaning hood. The inner cylinder is connected to the liquid replenishment mechanism through a water supply pipe.

[0011] As a further optimization of the present invention, the replenishment mechanism includes a mixing tube and a drug concentration monitoring probe inside the mixing tube. The mixing tube has a coaxial inner tube and a plurality of uniformly distributed through grooves on the side wall of the inner tube. One end of the inner tube is connected to an inlet pipe, and the whole formed by the inlet pipe and the inner tube is rotatably connected to the mixing tube. The water inlet end of the inlet pipe is provided with a replenishment pipe for connecting an external polishing agent supply source. The end of the mixing tube away from the inlet pipe is connected to a water inlet pipe, and the water inlet pipe is connected to a water supply pipe through a flow control valve.

[0012] As a further optimization of the present invention, a through groove is provided directly below the mixing pipe, a sealing plate for blocking the through groove is provided on the outer side of the inner pipe, an external toothed ring is sleeved on the outer side of the inlet pipe, and a drive gear for driving the external toothed ring is provided on the outer side of the polishing groove.

[0013] As a further optimization of the present invention, a zipper surface treatment method includes the following specific steps:

[0014] S1. Set the zipper surface treatment equipment at the output end of the zipper production line, or use an unwinding machine to set the rolled zipper at the input end of the zipper surface treatment equipment. Then, pull the free end of the zipper to wind through a conveyor roller and several traction rollers away from the cleaning mechanism. Then, pull the free end of the zipper to pass between the cleaning hood and the mesh cylinder and wind around the outer wall of the mesh cylinder. Finally, pull the zipper to wind through another conveyor roller. The free end of the zipper can continue to be pulled to the subsequent processing equipment or fixed on the winding machine for winding.

[0015] S2. Inject a certain amount of polishing liquid into the polishing tank. Use the pipe outside the cleaning hood to connect the air chamber to the air source and the water chamber to the water source. The gas passes through the air chamber and is output through the channel connected to the air chamber to form an air curtain. Similarly, the cleaning water enters the water chamber and is output through the channel connected to the water chamber to form a water curtain.

[0016] S3. Start the conveyor rollers. With the cooperation of the two conveyor rollers, the zipper is continuously conveyed. The zipper is immersed in the polishing liquid for chemical polishing under the traction of the traction roller. Then it is conveyed to the position of the mesh cylinder. During the process of passing through the mesh cylinder, it first comes into contact with the air curtain and then with the water curtain, realizing the effect of controlling water first and then rinsing. Finally, the cleaned zipper can be output from the device under the traction of the conveyor roller at the output end.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. The zipper surface treatment equipment and method can sequentially control water flow and rinse the passing zipper through the air curtain and water curtain generated by the cleaning hood. The air curtain can blow away the polishing liquid attached to the zipper teeth and some of the polishing liquid absorbed by the cloth strip, which greatly reduces the burden of subsequent rinsing and helps to reduce the time and water consumption of the rinsing process.

[0019] 2. During the zipper cleaning process, some polishing liquid is blown away from the zipper at the water control stage. This portion of polishing liquid can move to the inner cylinder after passing through the mesh cylinder and fall back into the polishing tank along the inner wall of the inner cylinder. The remaining polishing liquid is carried away by the cleaning water during the rinsing stage and collected in the inner cylinder. This portion of polishing liquid can be recovered by entering the mixing pipe to prepare polishing liquid for replenishment. The above two recovery methods improve the utilization rate of polishing liquid and reduce consumption.

[0020] 3. Through the cooperation of the mixing tube, inner tube, infusion tube and sealing plate, the mixing of two liquids can be achieved by introducing the chemical replenishment solution and the mixed water generated during zipper cleaning into the mixing tube. When replenishing the polishing tank, the liquid introduced is the mixed polishing liquid. The replenishment solution and the original polishing liquid can be mixed evenly without stirring, making the operation convenient and efficient. Attached Figure Description

[0028] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] Example 1

[0030] like Figure 1-6 As shown, the zipper surface treatment equipment of this embodiment includes a polishing tank 1 for containing and heating polishing liquid, a thermometer 4 for monitoring the temperature of polishing liquid, a conveying roller 2 for introducing and then leading the zipper into the polishing tank 1, and a plurality of traction rollers 3 for pulling the zipper into the polishing liquid during the transmission process. It also includes a cleaning mechanism for cleaning residual polishing liquid on the zipper tape and a replenishing mechanism for replenishing polishing liquid into the polishing tank 1.

[0031] The cleaning mechanism includes an inner cylinder 5, a rotatable mesh cylinder 6 sleeved on the outside of the inner cylinder 5, and a cleaning hood 7 sleeved on the outside of the mesh cylinder 6. The inner cylinder 5 and the cleaning hood 7 are respectively fixed to the polishing tank 1. The mesh cylinder 6 is used for directional transmission of the zipper, and the cleaning hood 7 is used to generate an air curtain and a water curtain. The cleaning hood 7, together with the mesh cylinder 6, is used to first control the water flow of the zipper wound on the mesh cylinder 6, and then rinse it with water. The inner cylinder 5 is used to collect the mixed liquid generated by rinsing the zipper and transport the mixed liquid into the replenishment mechanism to prepare polishing liquid.

[0032] When the zipper passes between the cleaning hood 7 and the mesh cylinder 6, the zipper first comes into contact with the air curtain. As the air curtain passes through the zipper, it carries away the polishing liquid adhering to the surface of the zipper teeth and the polishing liquid absorbed in the zipper tape, thus achieving the effect of water control. The polishing liquid that has detached from the zipper can be carried by the air curtain through the mesh cylinder 6 to the side wall of the inner cylinder 5, and then slide down the side wall of the inner cylinder 5 and finally fall back into the polishing tank 1. After the water control treatment, the zipper is continued to come into contact with the water curtain, which can rinse the water-controlled zipper. Since the previous water control treatment has greatly reduced the amount of polishing liquid on the surface of the zipper teeth and absorbed by the tape, the time and water consumption of the rinsing step can be greatly reduced. Moreover, the mixture of polishing liquid and cleaning water generated during rinsing can be transported to the liquid replenishment mechanism for recycling. Polishing liquid can be prepared by simply adding an appropriate amount of agent to the mixture.

[0033] The cleaning hood 7 has an arc-shaped structure and is fitted above the mesh cylinder 6. The cleaning hood 7 has an air chamber 10 and a water chamber 11 inside, and several channels for water and air passage are opened in the side wall of the cleaning hood 7. The outer side of the cleaning hood 7 is provided with pipes for connecting to external water and air sources. After the air source is connected to the air chamber 10, air continuously enters the air chamber 10. As the gas continuously overflows through the channels connected to the air chamber 10, the air chamber 10 will gradually be filled. After the air chamber 10 is filled, gas can be evenly overflowed in each channel connected to the air chamber 10, thereby forming an air curtain between the cleaning hood 7 and the mesh cylinder 6. Similarly, the cleaning water will form a water curtain between the cleaning hood 7 and the mesh cylinder 6 after passing through the water chamber 11 and the channels connected to the water chamber 11.

[0034] The mesh cylinder 6 includes several support rings 601 arranged in a linear array, and a support mesh 602 is provided between two adjacent support rings 601. The support mesh 602 has a ring structure. Several ring grooves corresponding to the support mesh 602 are opened in the side walls of the conveying roller 2 and the traction roller 3. The water passage groove and the air passage groove on the cleaning cover 7 correspond to the support mesh 602. The zipper is locked in the ring groove for transmission, which can prevent the zipper from shifting left and right, and is conducive to stable transmission.

[0035] The end face of the support ring 601 is provided with an internal toothed ring 12, and the end face of the inner cylinder 5 is provided with a drive gear for driving the internal toothed ring 12. The side wall of the inner cylinder 5 is provided with a water inlet 8 that is opposite to the water cavity 11 in the cleaning hood 7. The inner cylinder 5 is connected to the liquid replenishment mechanism through the water supply pipe 9. After the drive gear is turned on, it can drive the entire structure formed by the internal toothed ring 12 and the mesh cylinder 6 to rotate. During the transmission of the zipper, the mesh cylinder 6 rotates continuously in coordination with the transmission of the zipper, while the cleaning hood 7 and the inner cylinder 5 remain stationary. The air curtain and water curtain continuously generated by the cleaning hood 7 remain in the same position, and the relative position of the water curtain and the water inlet 8 on the inner cylinder 5 remains unchanged. After the water curtain passes through the zipper and the mesh cylinder 6, it can enter the inner cylinder 5 from the water inlet 8 and finally enter the liquid replenishment mechanism through the water supply pipe 9.

[0036] The replenishment mechanism includes a mixing tube 13, which contains a reagent concentration monitoring probe. A coaxial inner tube 17 is located within the mixing tube 13, and several evenly distributed through-grooves are formed on the side wall of the inner tube 17. One end of the inner tube 17 is connected to an inlet tube 15, and the inlet tube 15 and the inner tube 17 are rotatably connected to the mixing tube 13. The inlet end of the inlet tube 15 is equipped with a replenishment tube 16 for connecting an external polishing reagent supply source. The end of the mixing tube 13 away from the inlet tube 15 is connected to a water inlet tube 14, which is connected to a water supply pipe 9 via a flow control valve. When using this equipment, it should be ensured that the liquid level in the polishing tank 1 is always below the mixing tube 13. After connecting the reagent supply source via the replenishment tube 16, a connection is made between the water supply pipe 9 and the water inlet tube 14. The flow control valve and the connecting replenishment pipe 16 and the inlet pipe 15 are opened intermittently. When the two flow control valves are closed, the mixed liquid generated from cleaning the zipper is stored in the inner cylinder 5 and the water supply pipe 9. When the two flow control valves are opened at the same time, a certain amount of mixed liquid and a certain amount of chemical replenishment liquid can be input into the mixing pipe 13. The two are mixed to obtain polishing liquid. During the input process, part of the mixed liquid will be output from the end of the inner pipe 17. This part of the mixed liquid will be flushed with the chemical replenishment liquid. Another part of the mixed liquid will be output from the through groove in the side wall of the inner pipe 17. This is conducive to the rapid and uniform mixing of the mixed liquid and the chemical replenishment liquid. When the chemical concentration monitoring probe in the mixing pipe 13 detects the qualified concentration, the polishing liquid prepared in the mixing pipe 13 can be input into the polishing tank 1.

[0037] A through groove is provided directly below the mixing pipe 13. A sealing plate 18 for sealing the through groove is provided on the outside of the inner pipe 17. An external gear ring 19 is sleeved on the outside of the inlet pipe 15, and a drive gear for driving the external gear ring 19 is provided on the outside of the polishing groove 1. When the drive gear is turned on, the entire assembly consisting of the external gear ring 19, the inlet pipe 14, the inner pipe 17, and the sealing plate 18 can be rotated. The sealing plate 18 can then be removed from above the through groove of the mixing pipe 13, and the polishing liquid in the mixing pipe 13 can be completely output. Then, by controlling the drive gear to rotate in the opposite direction, the sealing plate 18 can be returned to its original position to reseal the mixing liquid.

[0038] A zipper surface treatment method, the specific steps of which are as follows:

[0039] S1. Set the zipper surface treatment equipment at the output end of the zipper production line, or use an unwinding machine to set the rolled zipper at the input end of the zipper surface treatment equipment. Then, pull the free end of the zipper to wind through a conveyor roller 2 and several traction rollers 3 away from the cleaning mechanism. Then, pull the free end of the zipper to pass through the cleaning hood 7 and the mesh cylinder 6 and wind around the outer wall of the mesh cylinder 6. Finally, pull the zipper to wind through another conveyor roller 2. The free end of the zipper can continue to be pulled to the subsequent processing equipment or fixed on the winding machine for winding.

[0040] S2. Inject a certain amount of polishing liquid into the polishing tank 1. Use the pipe outside the cleaning hood 7 to connect the air source to the air chamber 10 and the water source to the water chamber 11. The gas passes through the air chamber 10 and is output through the channel connected to the air chamber 10 to form an air curtain. Similarly, the cleaning water enters the water chamber 11 and is output through the channel connected to the water chamber 11 to form a water curtain.

[0041] S3. Turn on the conveyor roller 2. With the cooperation of the two conveyor rollers 2, the zipper is continuously conveyed. The zipper is immersed in the polishing liquid for chemical polishing under the traction of the traction roller 3. Then it is conveyed to the position of the mesh cylinder 6. During the process of passing through the mesh cylinder 6, it first contacts the air curtain and then the water curtain, realizing the effect of controlling water first and then rinsing. Finally, the cleaned zipper can be output from the device under the traction of the conveyor roller 2 at the output end.

[0042] The above-described embodiments are merely one implementation of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
