Description

Technical Field

[0001] This utility model relates to the technical field of metal bottle cap processing equipment, and in particular to an automatic conveying mechanism for surface treatment of metal bottle caps. Background Technology

[0002] In the production of metal bottle caps, surface treatment processes such as spraying and electroplating are key steps to improve the appearance quality and corrosion resistance of the products. In order to achieve continuous and automated production, it is usually necessary to use an automatic conveying mechanism in conjunction with special fixtures to stably transport the metal bottle caps to each processing station.

[0003] Existing conveying mechanisms for surface treatment of metal bottle caps have certain limitations in practical use. Due to the wide variety of specifications and models of metal bottle caps, different sizes or shapes of clamps are often required to ensure the clamping effect when producing different batches of products. However, the clamping installation method of existing conveying mechanisms mostly adopts rigid connection structures such as bolt fastening. This connection method makes the disassembly and assembly operation cumbersome and time-consuming when changing clamps, which seriously affects the changeover efficiency of the production line. Moreover, rigid contact can easily cause mechanical damage to the surface of the precision-machined bottle caps during the clamping process.

[0004] Existing rigid-connection fixture structures are often difficult to perform deep automated online cleaning. After multiple surface treatment operations, residual paint, dust or oil stains are easily attached to the fixture surface. If these contaminants are not removed in time, they are very likely to be transferred to the surface of the metal bottle cap during subsequent transportation, resulting in quality defects such as spraying pinholes or reduced coating adhesion, thereby reducing the yield of the final product.

[0005] Therefore, this utility model proposes an automatic conveying mechanism for surface treatment of metal bottle caps to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems in the prior art, the metal bottle cap conveying mechanism clamps usually adopt rigid connection, which makes it cumbersome to change clamps of different specifications and easily damages the bottle cap surface. In addition, the lack of effective automatic cleaning means leads to the transfer of contaminants and affects the process quality. The present invention aims to provide an automatic conveying mechanism for metal bottle cap surface treatment with an improved structure that can effectively solve the above problems.

[0007] This utility model provides an automatic conveying mechanism for surface treatment of metal bottle caps, including: a machine tool, and an operation box fixedly connected to the front side of the top wall of the machine tool. A fixed seat is fixedly connected to the bottom wall of the operation box. An n-shaped groove is opened in the inner wall of the fixed seat. A sliding groove is opened in the upper part of the closed side of the inner wall of the n-shaped groove. A circular groove is opened in the middle and lower part of the closed side of the inner wall of the n-shaped groove. A slide bar is slidably connected to the inner wall of the sliding groove. The outer wall of the slide bar is fixedly connected to the outer wall of the buckle block.

[0008] The buckle has a fixing tooth on one side and a push groove on the bottom. The mounting block is slidably connected to the opening on the other side of the inner wall of the fixing seat. The mounting block has a buckle tooth on the upper middle part of one side and a clamping arm is fixedly connected to the bottom wall of the mounting block.

[0009] Furthermore, the snap teeth and the fixed teeth are combined by interlocking. A circular block is rotatably connected to the inner wall of the circular groove. The outer wall of the circular block is fixedly connected to the outer wall of the rotating column. A push block is fixedly connected to the upper part of the outer wall of the rotating column. One side of the outer wall of the push block abuts against the inner wall of the push groove.

[0010] Preferably, a square hole is provided on the front side of the outer wall of the round block, the inner wall of the square hole abuts against the rear side of the outer wall of the fixing bolt, the rear side of the outer wall of the fixing bolt is a square block, and a thread is provided in the middle of the outer wall of the fixing bolt, and the thread is rotatably connected to the hole provided in the lower middle part of the front side of the outer wall of the fixing seat.

[0011] Preferably, a mounting plate is fixedly connected to the upper middle part of the front side of the inner wall of the control box, and a mounting seat is fixedly connected to the front side of the top wall of the mounting plate. An electric push rod is rotatably connected to the inner wall of the mounting seat.

[0012] Preferably, the output end of the electric push rod is rotatably connected to the bottom of the outer wall of the traction bar, and one side of the outer wall of the traction bar is fixedly connected to one side of the connecting block.

[0013] Preferably, the other side of the connecting block is fixedly connected to one side of the outer wall of the back plate, the bottom wall of the back plate is rotatably connected to the inner wall of the second mounting base, and the bottom wall of the second mounting base is fixedly connected to the top wall of the mounting plate.

[0014] Preferably, a nozzle is fixedly connected to the upper part of the back plate.

[0015] Preferably, the fixing seat, the fastener, the mounting block and the rotating column constitute the replacement mechanism, which is symmetrically arranged on the bottom wall of the fixture, and the clamping arm constitutes part of the fixture.

[0016] Preferably, the cleaning mechanism consists of a mounting plate, an electric push rod, and a spray nozzle.

[0017] This utility model has the following beneficial effects: 1. This utility model, by setting a replacement mechanism in the fixed seat at the bottom of the operating box, uses the rotating fixing bolt to drive the rotating column and push block to rotate, thereby driving the buckle block to slide along the slide groove, so that the fixing teeth on the side of the buckle block and the buckle teeth on the side of the mounting block can be locked or separated. This solves the problem that the clamps of the metal bottle cap conveying mechanism in the prior art usually use rigid connection, which makes it cumbersome to change different specifications of clamps and easily damages the surface of the bottle cap. It achieves the effect of quickly and flexibly changing different specifications of clamping arms to adapt to a variety of bottle caps, avoiding rigid contact damage to the bottle caps, and significantly improving the flexibility of the conveying mechanism and the surface treatment yield.

[0018] 2. This utility model solves the problem in the prior art where the lack of effective automatic cleaning means for the fixture during long-term use leads to the accumulation of dust and oil on the surface of the bottle cap, and the transfer of these pollutants to the bottle cap surface. It achieves dynamic multi-angle cleaning of the fixture without dead angles, thoroughly removes attached contaminants, effectively prevents process defects such as spraying pinholes or reduced electroplating adhesion, and ensures the stability of the subsequent surface treatment quality of the metal bottle cap.
