Description

Technical Field

[0001] This invention belongs to the field of zipper head dyeing technology, specifically relating to a device for dyeing brass zippers with an antique bronze color. Background Technology

[0002] my country is a major zipper manufacturing country. Metal zippers are mid-to-high-end products, with brass zippers being the main type, widely used in clothing, bags, and footwear. The antique bronze color of brass zippers has always been popular, and they have significant development potential both domestically and internationally.

[0003] The coloring process for copper and copper alloys generally consists of three stages: pretreatment, coloring, and post-treatment. Sufficient attention must be paid to the pretreatment process when coloring copper parts; otherwise, uneven coloring of the film layer can easily occur, leading to variations in the surface quality of the film.

[0004] Some existing technologies also include dyeing solutions for brass parts, such as a Chinese patent with publication number CN100577871C, which discloses a process for dyeing the surface of brass parts red bronze. The process is simple, easy to master, has a short process, and is inexpensive, making it a practical metal surface plating process.

[0005] However, the pretreatment in this patent is a common chemical polishing process, which is prone to uneven gloss and cloud-like patterns, affecting the dyeing quality of the zipper head. Moreover, chemical polishing produces harmful chemical waste liquid, causing environmental pollution. Summary of the Invention

[0006] The purpose of this invention is to provide a device for dyeing brass zippers to an antique bronze color in order to solve the problems mentioned in the background art.

[0007] The present invention achieves the above objectives through the following technical solutions:

[0008] A brass zipper dyeing device is used for pre-treatment of brass zipper heads to dye them bronze. It includes a mounting frame with a plurality of clamping components along its length. The clamping components include a first plate and a second plate that are parallel to each other and used to clamp the zipper head. The mounting frame is provided with a drive component for moving the second plate to rotate the zipper head.

[0009] The zipper head is clamped equidistantly between plates one and two and then immersed in the treatment tank along with the treatment device. During immersion, plate one remains vertical. The zipper head is simultaneously chemically and fluidly polished using the flowing treatment liquid. During the polishing process, plate two moves relative to plate one so that different sides of the zipper head can come into contact with the treatment liquid.

[0010] Preferably, the drive assembly includes a telescopic component, the telescopic end of which is provided with a connecting plate, the connecting plate is provided with a rectangular plate, and a straight plate is provided between the rectangular plate and each of the second plates.

[0011] Preferably, the telescopic component and the connecting plate are not fixedly connected. The telescopic end of the telescopic component passes through the connecting plate and is connected to a connecting rod. The connecting rod is provided with a No. 3 plate. The No. 3 plate is provided with two rope groups located on the front and back of the mounting frame respectively. Each rope group includes several connecting ropes.

[0012] Both the No. 1 and No. 2 plates are provided with several mounting grooves in the opposite direction along their length. Rotatable clamping blocks are provided at the mounting grooves. The connecting ropes in the two rope groups are connected to the clamping blocks one by one from top to bottom. The connecting ropes are used to drive the clamping blocks and the zipper head to switch between tilt and pitch modes.

[0013] The mounting bracket is provided with a limiting groove for limiting the position of the second plate.

[0014] Preferably, the clamping block is provided with a limiting block to prevent the zipper head from shifting.

[0015] Preferably, the clamping block is made of an elastic material.

[0016] Preferably, the straight plate is provided with a plurality of cards along its length direction, and the cards are provided with a plurality of first magnetic blocks along the extension direction of the telescopic member. The second plate is provided with a plurality of second magnetic blocks with opposite magnetic properties to the first magnetic blocks. The first magnetic blocks are used to generate relative displacement with the second magnetic blocks when the second plate stops moving, so that the second magnetic blocks drive the second plate to vibrate.

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

[0018] This invention employs fluid polishing to perform a thorough pre-dyeing treatment on the zipper head, thereby improving the surface quality of the zipper head. While maintaining precision, it also reduces processing time and costs, and generates less waste liquid during the process, resulting in less environmental pollution. Attached Figure Description

[0025] The present application will now be described in further detail. 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.

[0026] Example 1

[0027] like Figure 1-5 As shown, a brass zipper dyeing device is used for pretreatment of brass zipper heads 2 to dye them bronze. It includes a long strip-shaped mounting frame 1, which is kept horizontal. Several clamping components are provided on the mounting frame 1 along its length. Each clamping component includes a first plate 3 and a second plate 4 that are parallel to each other and used to clamp the zipper head 2. The first plate 3 is fixedly installed on the mounting frame 1. The mounting frame 1 is provided with a limiting groove 17 for limiting the second plate 4. The second plate 4 is located in the limiting groove 17. The first plate 3 is perpendicular or approximately perpendicular to the mounting frame 1 and is in a vertical state. The second plate 4 is movably set in the through groove of the mounting frame 1.

[0028] The mounting frame 1 is fixedly equipped with a telescopic component 5. The telescopic component 5 extends laterally and can be operated by an electric push rod or a hydraulic cylinder. The telescopic end of the telescopic component 5 is fixedly equipped with a connecting plate 16. The connecting plate 16 is fixedly connected to a rectangular plate 13 parallel to the mounting frame 1. Several straight plates 14 fixedly connected to the second plate 4 are fixedly mounted on the rectangular plate 13.

[0029] It should be noted that the zipper head 2 is equidistantly clamped between plate 3 and plate 4, and immersed in the treatment tank along with the treatment device. During immersion, plate 3 remains vertical, while the zipper head 2 remains horizontal. A high-speed flowing treatment liquid impacts the zipper head 2, passing through its interior. The treatment liquid is a combination of chemical polishing and fluid polishing liquid, or a single fluid polishing liquid. During polishing, the telescopic component 5 moves the rectangular plate 13 and the straight plate 14, causing plate 4 to move laterally. This movement of plate 4 causes the zipper head 2 to rotate laterally, ensuring that different sides of the zipper head 2 come into full contact with the treatment liquid.

[0030] Furthermore, a limiting block 9 is fixed on plate 3 or plate 4 to prevent the zipper head 2 from shifting. When the zipper head 2 is placed between plate 3 and plate 4, the bottom plane of the zipper head 2 abuts against the upper surface of the limiting block 9. This ensures that the zipper head 2 and the clamping block 8 are in the correct relative position when the zipper head 2 rotates horizontally or tilts vertically.

[0031] Furthermore, several cards 10 are fixedly mounted on plate 15. Several first-order magnetic blocks 11 are arranged on each card 10 along the telescopic direction of the telescopic component 5. Correspondingly, several second-order magnetic blocks 12 with opposite magnetic properties to the first-order magnetic blocks 11 are arranged on the straight plate 14. When the first-order magnetic blocks 11 move relative to the second-order magnetic blocks 12, they exert forces in different directions on the second-order magnetic blocks 12, causing the second-order magnetic blocks 12 to move laterally back and forth, thus causing plate 4 to vibrate to a certain extent. This vibration causes the zipper head 2 to shake, further accelerating the separation of excess material adhering to the surface of the zipper head 2 from the zipper head 2, thereby improving the polishing efficiency.

[0032] Example 2

[0033] Unlike Embodiment 1, the telescopic end of the telescopic component 5 is not rigidly connected to the rectangular plate 13. The telescopic end of the telescopic component 5 passes through the connecting plate 16 and is fixedly connected to the connecting rod 6. The connecting rod 6 is fixed with the No. 3 plate 15. The No. 3 plate 15 is fixed with two rope groups along the front and back sides of the mounting frame 1. Each rope group includes several connecting ropes 7.

[0034] Both plate 3 and plate 4 have several mounting grooves running in opposite directions along their length. Rotatable clamping blocks 8 are located at these grooves, with their rotation axes parallel to the mounting frame 1. Connecting ropes 7 extend from the top to the bottom of plates 3 and 4 and are fixedly connected to the clamping blocks 8 one by one. The telescopic end of the telescopic component 5 moves the connecting plate 16 through friction. When the connecting plate 16 and plate 4 cannot move, the telescopic end continues to extend, causing plate 15 to continue moving. Taking the figure as an example, the extension direction of the telescopic component 5 is the forward direction. Plate 15 pulls the connecting rope 7 (front of mounting frame 1) in the forward direction, causing the connecting rope 7 to pull the clamping blocks 8 to rotate. When the clamping blocks 8 rotate, the zipper head 2 tilts backward, allowing the treatment fluid to contact the bottom and top of the zipper head 2. Conversely, when the telescopic end shortens, it is the backward direction. The connecting rope 7 pulls the connecting rope 7 (back of mounting frame 1) in the backward direction, causing the clamping blocks 8 to tilt the zipper head 2 forward. Different tilt angles allow different parts of the zipper head 2 to be treated with the treatment liquid, improving the uniformity of the coloring of the zipper head 2.

[0035] The clamping blocks 8 are made of elastic material. Because the zipper head 2 has different widths when it rotates horizontally, the clamping blocks 8 are made of elastic material so that the zipper head 2 can be firmly clamped by the two clamping blocks 8 when it rotates horizontally, which can prevent damage to the zipper head 2 and also effectively clamp the zipper head 2.

[0036] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively 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.
