Description

Technical Field

[0001] This application relates to the field of powder coating technology, and in particular to an auxiliary mechanism for powder coating equipment. Background Technology

[0002] Powder coating is a surface treatment process that uses electrostatics to adsorb plastic powder onto the surface of a workpiece and then cures it. Powder coating can form a dense protective coating on the surface of a workpiece and is commonly seen in light industry and home decoration.

[0003] In the prior art, a powder coating equipment with a positioning mechanism is disclosed in CN219519336U. During use, the workpiece is fixed by clamping it with a clamping mechanism. At the same time as the workpiece is clamped by the clamping mechanism, a wire brush scrapes the surface of the workpiece that needs to be powder coated.

[0004] However, when the device is used to fix the workpiece, the transmission rod and the first bevel gear rotate synchronously. When the sliding block and the positioning block come close to each other, the wire brush continuously cleans the surface of the workpiece. At this time, the workpiece is not in a clamped state. The workpiece is easily displaced by the friction force generated by the wire brush, which makes the positioning accuracy worse and is inconvenient to use. When the sliding block and the positioning block clamp the workpiece, the support rod cannot rotate, so the position of the wire brush cannot be easily adjusted, which affects the subsequent spraying operation.

[0005] Therefore, this application provides an auxiliary mechanism for powder coating equipment to meet the requirements. Utility Model Content

[0006] In view of this, the purpose of this application is to provide an auxiliary mechanism for a powder coating equipment, which can conveniently limit the workpiece and reduce workpiece displacement, while also allowing the cleaning mechanism to be flexibly adjusted so that it stays in an idle position and avoids obstructing subsequent spraying operations.

[0007] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0008] An auxiliary mechanism for a powder coating equipment includes a frame and a powder coating mechanism on top. A slide rail is installed in the middle of the frame, and two slidable clamping blocks are respectively provided at both ends of the slide rail. Each clamping block includes a horizontal part for supporting the workpiece and a vertical part for limiting the lateral movement space of the workpiece. A transmission rod is passed between the two clamping blocks. The transmission rod has threads on its surface and meshes with the clamping blocks. A servo motor is fixedly connected to the end of the slide rail, and a drive gear is fixedly connected to the output end of the servo motor. A slidable connecting block is provided on the side of the drive gear facing the transmission rod, and a lever is engaged in the groove on the surface of the connecting block.

[0009] A sleeve is penetrated through the top of the slide rail. A connecting rod is embedded at the top of the sleeve. A brush plate is arranged on one side of the connecting rod. A driven gear is fixedly connected to the bottom surface of the sleeve. The driven gear meshes with a driving gear.

[0010] Preferably, the horizontal portion of the clamping block abuts against the upper surface of the slide rail.

[0011] Preferably, the vertical projection of the vertical portion of the clamping block is in the shape of a "C", and the opening direction of the vertical portion of the clamping block faces the clamping direction.

[0012] Preferably, a clamping groove is formed on one side of the connecting block facing the driving gear, and a protrusion corresponding to the connecting block is arranged on the end face of the driving gear.

[0013] Preferably, a limiting seat is arranged at the inner bottom end of the slide rail. The transmission rod penetrates through the limiting seat. A spring is arranged between the end of the connecting block and the limiting seat.

[0014] Preferably, a strip-shaped groove is formed on the side wall of the slide rail. The dial rod penetrates through the strip-shaped groove on the side wall of the slide rail.

[0015] Preferably, the sleeve and the connecting rod are integrally connected by a positioning pin shaft, and a row of vertical pin holes are formed on the surface of the sleeve.

[0016] Compared with the prior art, the present application has at least the following beneficial effects:

[0017] In the above solution, by arranging the clamping block, the workpiece is placed on the surface of the clamping block. The horizontal portion of the clamping block supports the workpiece from below, and the vertical portion of the clamping block limits the lateral movement space of the workpiece to prevent the lateral displacement of the workpiece. It is more convenient during clamping and fixing, and at the same time, a gap is maintained between the bottom of the workpiece and the surface of the frame to avoid contact between the workpiece and impurities on the surface of the frame.

[0018] In the above solution, by arranging the connecting block, the dial rod and the transmission rod, by controlling the position of the dial rod, the transmission state between the connecting block and the driving gear is controlled, so that while the brush plate rotates, the two clamping blocks can stably clamp the workpiece, and the position of the brush plate can still be flexibly adjusted to stay in the idle position to avoid blocking the subsequent spraying operation.

[0026] like Figure 1 , Figure 2 , Figure 3 An auxiliary mechanism for a powder coating equipment is shown in the embodiment of this application. It includes a frame 1 and a powder coating mechanism 2 on top of it. A slide rail 3 is installed in the middle of the frame 1. Two slidable clamping blocks 301 are respectively provided at both ends of the slide rail 3. The clamping block 301 includes a horizontal part for supporting the workpiece and a vertical part for limiting the lateral movement space of the workpiece. A transmission rod 302 is passed between the two clamping blocks 301. The surface of the transmission rod 302 is provided with threads and meshes with the clamping blocks 301. A servo motor 4 is fixedly connected to the end of the slide rail 3. A drive gear 401 is fixedly connected to the output end of the servo motor 4. A slidable connecting block 402 is provided on the side of the drive gear 401 facing the transmission rod 302. A lever 403 is engaged in the groove on the surface of the connecting block 402.

[0027] A sleeve 5 is inserted through the top of the slide rail 3, a connecting rod 501 is embedded in the top of the sleeve 5, a brush plate 502 is provided on one side of the connecting rod 501, and a driven gear 503 is fixedly connected to the bottom surface of the sleeve 5. The driven gear 503 meshes with the driving gear 401.

[0028] By placing the workpiece on the surface of the clamping block 301, the horizontal part of the clamping block 301 supports the workpiece from below, and the vertical part of the clamping block 301 limits the lateral movement space of the workpiece to prevent lateral displacement of the workpiece, making it more convenient to clamp and fix. At the same time, a gap is maintained between the bottom of the workpiece and the surface of the frame 1 to avoid contact between the workpiece and impurities on the surface of the frame 1.

[0029] The servo motor 4 drives the driving gear 401 to rotate. The connecting block 402 is clamped on one side of the transmission rod 302. The connecting block 402 is pressed against the driving gear 401 by the lever 403. The synchronous rotation of the connecting block 402 and the driving gear 401 can be achieved by using the frictional force, so that the two clamping blocks 301 are displaced by the thread on the outer side of the transmission rod 302;

[0030] The thread on the surface of the transmission rod 302 is a double thread, so that the two clamping blocks 301 can approach each other to clamp the workpiece;

[0031] When the driving gear 401 drives the driven gear 503 to rotate, the sleeve 5 drives the connecting rod 501 to rotate, so that the brush plate 502 rotates. The brush plate 502 reciprocates on the surface of the workpiece, and the impurities on the surface of the workpiece are removed by the brush plate 502 to facilitate subsequent spraying;

[0032] By controlling the position of the lever 403, the transmission state between the connecting block 402 and the driving gear 401 is controlled, so that the two clamping blocks 301 can stably clamp the workpiece while the brush plate 502 rotates, and the position of the brush plate 502 can still be flexibly adjusted to stay in the idle position to avoid blocking the subsequent spraying operation.

[0033] In this embodiment, as Figures 2-4 shown; the horizontal part of the clamping block 301 abuts against the upper surface of the slide rail 3;

[0034] The clamping block 301 is supported by the upper surface of the slide rail 3, and has high and stable bearing capacity, and can maintain the stability of the workpiece during the fixing process;

[0035] The vertical projection of the vertical part of the clamping block 301 is in the shape of a "匚", and the opening direction of the vertical part of the clamping block 301 faces the clamping direction;

[0036] The vertical part of the clamping block 301 has two right angles, which can be clamped on the end angle of the workpiece, and the two clamping blocks 301 can abut against each other to form a closed rectangular structure to further limit the lateral movement space of the workpiece and prevent the workpiece from moving laterally;

[0037] A clamping groove is formed on one side of the connecting block 402 facing the driving gear 401, and a protrusion corresponding to the connecting block 402 is provided on the end face of the driving gear 401;

[0038] The connecting block 402 and the driving gear 401 can also be clamped, and the torque is transmitted by the clamping to accurately and stably transmit the power;

[0039] A limit seat 303 is provided at the inner bottom end of the slide rail 3. The transmission rod 302 penetrates through the limit seat 303, and a spring 404 is provided between the end of the connecting block 402 and the limit seat 303;

[0040] Spring 404 is used to limit the position of connecting block 402, so that connecting block 402 can stably abut against drive gear 401, so that power can be transmitted smoothly.

[0041] The slide rail 3 has a strip groove on its side wall, and the lever 403 passes through the strip groove on the side wall of the slide rail 3.

[0042] The lever 403 is engaged with the groove on the outer circumference of the connecting block 402. When the connecting block 402 rotates, the lever 403 remains in contact with the connecting block 402. The lever 403 is limited by the strip groove on the side wall of the slide rail 3, which can achieve a good control effect on the connecting block 402.

[0043] The sleeve 5 and the connecting rod 501 are connected as one unit by a positioning pin, and the surface of the sleeve 5 is provided with vertically arranged pin holes.

[0044] The relative position between the sleeve 5 and the connecting rod 501 is adjustable to accommodate workpieces of different heights.
