Description

Technical Field

[0001] This invention relates to the field of watch strap polishing and processing, and more particularly to a mechanical watch strap wire drawing device. Background Technology

[0002] Brushed texture is a high-end decorative technique. After manual brushing and polishing of mechanical watch straps, the micro-concave and convex surface formed by the fine metal lines not only enhances the visual texture and layering, but also effectively conceals minor scratches from use, maintaining the watch's fresh appearance. This is considered an essential process in haute horlogerie. However, improper manual brushing and polishing can easily lead to chaotic surface texture, deformed shape, damage to the gold plating, or unevenness at the seams, affecting the overall aesthetics. In addition, watch straps are usually made of high-hardness alloys such as stainless steel, and the hand is easily injured by the electric brushing wheel and sparks when moving the strap back and forth. The manual polishing process generates a large amount of metal dust and debris, which can easily be inhaled into the respiratory tract, causing metal dust allergies or lung irritation. Long-term inhalation may even lead to respiratory diseases. Summary of the Invention

Detailed Implementation

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] Example 1: A mechanical watch strap drawing device, such as... Figures 1-6 As shown, the system includes a mounting frame 11, an electric lift 12, a fixture 13, an electric wire drawing wheel 14, a lower crescent-shaped plate 21, an upper crescent-shaped plate 22, a first electrically controlled push rod 23, a lower conveyor belt 24, a drive motor 25, a transmission gear 26, and an upper conveyor belt 27. The electric lift 12 is mounted on the mounting frame 11. The electric wire drawing wheel 14 is connected to the electric lift 12 via the fixture 13. The fixture 13 is an electric turntable that can drive the electric wire drawing wheel 14 to rotate around a vertical axis. The lower crescent-shaped plate 21 is fixedly connected to the mounting frame 11. The upper crescent-shaped plate 22 is slidably connected to the lower crescent-shaped plate 21, and the upper crescent-shaped plate... The toothed disc 22 is aligned directly below the electric wire drawing wheel 14; two first electrically controlled push rods 23 are installed on the lower crescent disc 21; the telescopic ends of the two first electrically controlled push rods 23 are fixedly connected to the upper crescent disc 22; a lower conveyor belt 24 is wound around the outer surface of the lower crescent disc 21; several transmission tooth grooves 2401 are opened on the inner side of the lower conveyor belt 24; a drive motor 25 is installed inside the lower crescent disc 21; a transmission gear 26 is fixedly connected to the output shaft of the drive motor 25; the transmission gear 26 meshes with the corresponding transmission tooth groove 2401 in the lower conveyor belt 24; an upper conveyor belt 27 is wound around the outer surface of the upper crescent disc 22.

[0019] like Figure 3 and Figure 5As shown, the upper conveyor belt 27 is designed as a convex structure that arches outward from the center; a crescent plate 31 is slidably connected to the front and rear sides of the upper crescent plate 22; a second electrically controlled push rod 32 is installed on the front and rear sides of the upper crescent plate 22; the telescopic ends of the two second electrically controlled push rods 32 are respectively fixed to the corresponding crescent plates 31; several rollers 33 are rotatably connected to each of the two crescent plates 31, and the rollers 33 on the crescent plates 31 are initially at the same height as the corresponding position on the surface of the upper conveyor belt 27. During the rotation of the watch strap driven by the lower conveyor belt 24 and the upper conveyor belt 27, the inner edge area of ​​the upper side of the watch strap moves closely against the rollers 33.

[0020] In the process of using the mechanical watch strap brushing device of the present invention, the operator first uses an auxiliary buckle to fasten and connect the two ends of the watch strap to be polished together, so that the watch strap is fitted in a complete ring structure between the lower crescent plate 21 and the upper crescent plate 22. Then, the first electronically controlled push rod 23 is controlled to push the upper crescent plate 22 to drive the upper conveyor belt 27 to rise. The upper crescent plate 22 pushes the watch strap upward until the middle of the watch strap is tightly attached to the outer surface between the lower conveyor belt 24 and the upper conveyor belt 27. The roller 33 on the crescent plate 31 is level with the corresponding position on the surface of the upper conveyor belt 27. At this time, the front of the upper side of the watch strap The rollers 33 on the two crescent plates 31 are closely attached to the rear two side edges. The staff then controls the drive motor 25 to drive the transmission gear 26 to rotate. The transmission gear 26 meshes with the transmission tooth groove 2401 to drive the lower conveyor belt 24 to rotate. The lower conveyor belt 24 drives the watch strap to rotate between the lower conveyor belt 24 and the upper conveyor belt 27, so that each link of the watch strap rotates in sequence to the alignment electric brushing wheel 14. Whenever a link of the watch strap rotates to the alignment electric brushing wheel 14, the staff controls the electric lifting platform 12 to drive the electric brushing wheel 14 down to approach the link of the watch strap and brush and polish its entire surface.

[0021] When each link of the watch strap consists of a central core and two side blocks connected to the front and rear sides of the central core, and only the central area of ​​the watch strap links needs to be brushed and polished, the worker controls the upper crescent plate 22 to open the watch strap upwards, while controlling the second electronically controlled push rod 32 to move the crescent plate 31 and roller 33 downwards to lower their position. This lowers the overall height of the crescent plate 31 and roller 33 below the upper surface of the upper conveyor belt 27. At this time, the outward-arching protrusion in the middle of the upper conveyor belt 27 will... The central core of the corresponding link of the watch strap is raised, so that the height of the central core of the link is higher than the height of the front and rear side blocks. When the electric lifting platform 12 drives the electric brushing wheel 14 to move down to the link of the watch strap, the electric brushing wheel 14 will only brush and polish the surface of the central core of the link. The staff can also control the retainer 13 to rotate and adjust it to any angle along the vertical central axis, so as to polish the surface of the watch strap link with brushed textures at different angles to meet various polishing needs.

[0022] like Figure 1 , Figure 5 and Figure 6 As shown, a waste collection box 15 aligned with the lower crescent-shaped plate 21 is placed on the mounting frame 11; the upper crescent-shaped plate 22 has several upward-through air intake channels 2201; the upper crescent-shaped plate 22 has an air outlet channel 2202 connecting all the air intake channels 2201; an electrically controlled suction machine 28 is installed in the air outlet channel 2202 of the upper crescent-shaped plate 22; the upper conveyor belt 27 has several ventilation holes 2701; the outlet end of the air outlet channel 2202 of the upper crescent-shaped plate 22 is designed to bend downwards towards the waste collection box 15; the operator controls the electric pull... During the brushing and polishing process of the wire wheel 14 near the watch strap, the electric brushing wheel 14 continuously polishes the watch strap, generating a large amount of polishing debris. At the same time, the electric suction machine 28 performs suction work on the air outlet channel 2202 and air inlet channel 2201 of the upper crescent plate 22, allowing the polishing debris hidden in the gaps between the links of the watch strap to be drawn into the air inlet channel 2201 through the ventilation hole 2701 structure of the upper conveyor belt 27. The electric suction machine 28 then blows the sucked polishing debris downward along the air outlet channel 2202 into the waste collection box 15, so as to avoid a large amount of polishing debris remaining in the gaps between the links of the watch strap.

[0023] Example 2, as Figures 1-6As shown, based on the above embodiment 1, the electric wire drawing wheel 14 in this embodiment is fixedly connected to a spray pipe 16, and the spray pipe 16 is externally connected to a lubricating fluid delivery device. When the watch strap to be wire drawn and polished is made of materials such as aluminum alloy that are prone to high-temperature oxidation, the operator starts the external lubricating fluid delivery device while controlling the electric wire drawing wheel 14 to approach the watch strap for wire drawing and polishing. The external lubricating fluid delivery device continuously sprays lubricating fluid onto the area of ​​the watch strap being polished by the electric wire drawing wheel 14 through the spray pipe 16. The lubricating fluid can not only reduce the heat generated by the electric wire drawing wheel 14 when polishing the watch strap, preventing the metal material of the watch strap from overheating and discoloring, but also reduce the wear generated by the electric wire drawing wheel 14 during the polishing process of the watch strap. The sprayed lubricating fluid finally falls down into the waste collection box 15 for collection.

[0024] Example 3, as Figures 1-6 As shown, based on the above embodiment 1, a movable slider 41 is slidably connected to the mounting bracket 11 in this embodiment; an electric polishing wheel 42 for polishing the watch strap surface is mounted on the movable slider 41. When there are dense processing marks in a local area on the outer surface of the watch strap, before performing wire-brushing and polishing treatment on the watch strap, the worker first rotates the watch strap sleeved between the lower conveyor belt 24 and the upper conveyor belt 27, so that the area of ​​the watch strap with dense processing marks is aligned with the electric polishing wheel 42. Then, the electric polishing wheel 42 is started, and the movable slider 41 is pushed to drive the electric polishing wheel 42 close to the area of ​​the watch strap with dense processing marks for polishing and polishing treatment, polishing the marks in the area of ​​the watch strap to a flat structure, and then performing wire-brushing and polishing treatment on the area of ​​the watch strap according to the steps of the above embodiment; a pressure is fixedly connected between the mounting bracket 11 and the movable slider 41. Spring 43; During the polishing process, when the operator pushes the movable slider 41 to drive the electric polishing wheel 42 close to the watch strap, the movable slider 41 compresses the spring 43. After the polishing process is completed, the operator releases the movable slider 41. At this time, the compressed spring 43 pushes the movable slider 41 to drive the electric polishing wheel 42 to move in the opposite direction and reset away from the watch strap. When the operator rotates the polished area of ​​the watch strap to align with the electric brushing wheel 14, the spring 43 has automatically driven the electric polishing wheel 42 on the movable slider 41 to move and reset. At this time, the electric polishing wheel 42 is in a state away from the watch strap. This avoids the electric polishing wheel 42 from repeatedly polishing the brushed area of ​​the watch strap during the rotation of the watch strap because the operator forgot to move and reset the electric polishing wheel 42.
