Description

Technical Field

[0001] This invention relates to the field of circuit breaker drawer processing technology, and in particular to a shell surface spraying device for processing circuit breaker drawers. Background Technology

[0002] Circuit breakers are important electrical components in low-voltage power distribution systems. They can not only connect and disconnect circuits infrequently under load, but also automatically trip and disconnect faulty circuits when short circuits, overloads, and low voltage (or loss of voltage) occur. Circuit breaker drawers are an indispensable and important component in the production of circuit breakers. In the production of circuit breaker drawers, their surfaces need to be treated by a spraying device to give them certain properties. Most existing spraying devices fix the workpiece with a clamp for spraying. However, during the clamping period, the workpiece has multiple contact surfaces, which makes it impossible to effectively spray multiple contact surfaces during the spraying process. Therefore, it is necessary to wait for the sprayed material to dry, then manually flip the workpiece and re-spray the contact surfaces. This makes the overall spraying operation cumbersome and complex, requiring a certain amount of time and effort. To address this, we propose a shell surface spraying device for processing circuit breaker drawers. Summary of the Invention

A second one-way gear is fixedly connected to the drive rod at the location corresponding to the second linkage gear. One side of the second one-way gear meshes with the other side of the second linkage gear for transmission.

[0010] Furthermore, a transmission assembly is provided between the rotating mechanism and the painting assembly.

In summary, this equipment can not only automatically transport the circuit breaker drawer housings to be processed, but also automatically change the angle of the circuit breaker drawer housings to be painted and switch between multiple circuit breaker drawer housings, ensuring that multiple circuit breaker drawer housings can be painted simultaneously. At the same time, it can ensure that any surface of the circuit breaker drawer housing can be painted evenly, improving the painting effect and efficiency. Attached Figure Description

[0022] In this invention, a transmission assembly 8 is provided between the rotating mechanism 3 and the painting assembly.

[0023] In this invention, a fixed frame 10 is fixedly connected to the bottom of the driven rod 902, and clamping components 11 are fixedly connected to both sides of the fixed frame 10. The circuit breaker drawer housing to be processed is clamped and fixed by the clamping components 11. A moving groove is opened at the top of the machine body 1 corresponding to the short shaft 204. The short shaft 204 moves through the moving groove, and the linkage frame 205 is movably sleeved in the machine body 1.

[0024] In this invention, a dust cover 12 is fixedly connected to the top of the body 1, an entrance and exit are opened on the front of the body 1, and a door is hinged to both sides of the entrance and exit. A support column is fixedly connected to the bottom of the body 1. The dust cover 12 provides dust protection for the moving mechanism 2 and the rotating mechanism 3.

[0025] Working principle and usage: When the drive motor 401 starts in the forward direction, it drives the drive gear 402 to rotate in the forward direction through the output shaft. When the drive gear 402 rotates in the forward direction, it meshes with the first connecting gear 502, thereby driving the rotation of the connecting rod 501. The rotation of the connecting rod 501 drives the rotation of the second connecting gear 503. The rotation of the second connecting gear 503 meshes with the first one-way gear 504 and the second one-way gear 305 respectively. Since the rotation of the first one-way gear 504 and the second one-way gear 305 are in opposite directions, when the first one-way gear 504 meshes with the reciprocating screw 201, the second one-way gear 305 cannot mesh with the drive rod 304. Therefore, when the reciprocating screw 201 rotates, the drive rod 304 remains stationary. When the reciprocating screw 201 rotates, it drives the moving frame 202 to move smoothly along the guide rod 203. When the moving frame 202 moves, it simultaneously drives the short shaft 204 and the connecting frame 205 to move. The movement of the connecting frame 205 drives the circuit breaker drawer housing on the clamping assembly 11 to move. When the moving frame 202 moves to the outermost thread end of the reciprocating screw 201, the drive motor 401 stops working, so that the reciprocating screw 201 stops rotating, thus facilitating the operator to perform circuit breaking after painting. The circuit breaker drawer housing is taken out, and the circuit breaker drawer housing that needs to be painted is placed on the clamping assembly 11. After placement, the drive motor 401 starts forward again, thereby driving the reciprocating screw 201 to rotate again. The reciprocating screw 201 rotates again, driving the moving frame 202 to move into the machine body 1. When the moving frame 202 moves to the threaded end of the other end of the reciprocating screw 201, the drive motor 401 stops, and the driven rubber wheel 303 and the drive rubber wheel 302 abut against each other. At this time, the drive motor 401 starts in reverse. When the drive motor 401 starts in reverse, it drives the drive gear 402 to rotate synchronously in reverse, thereby changing the rotation direction of the second linkage gear 503. Through the change in the rotation direction of the second linkage gear 503, the rotation directions of the first one-way gear 504 and the second one-way gear 305 are also changed. Because the rotation directions of the first one-way gear 504 and the second one-way gear 305 have changed, the rotation of the first one-way gear 504 does not mesh with the reciprocating screw 201, so that the reciprocating screw 201 remains stationary. At the same time, when the second one-way gear 305 rotates, it meshes with the drive rod 304 to transmit power. The movement of the drive rod 304 causes the drive rod 304 to rotate, which in turn causes the first bevel gear 306 and the second pulley 805 to rotate synchronously. The rotation of the first bevel gear 306 meshes with the second bevel gear 307, thereby causing the connecting rod 301 to rotate. The rotation of the connecting rod 301 causes the drive rubber wheel 302 to rotate, and at the same time, it causes the driven rubber wheel 303 to rotate. The rotation of the driven rubber wheel 303 causes the short shaft 204 to rotate, and the rotation of the short shaft 204 causes the linkage frame 205 to rotate synchronously. The rotation of the linkage frame 205 causes the switching of multiple circuit breaker drawer housings for painting. Simultaneously, the rotation of the linkage frame 205 drives the driven rod 902 and the driven gear 903 to rotate circumferentially, so that the driven gear 903 meshes with the half-tooth ring 901 for transmission. The rotation of the driven gear 903 drives the rotation of the driven rod 902, and at the same time drives the fixed frame 10 to rotate circumferentially. Through the circumferential rotation of the fixed frame 10, the paint surface of the circuit breaker drawer housing to be painted is changed, thereby ensuring that any side of the circuit breaker drawer housing can be painted simultaneously. The rotation of the second pulley 805 drives the rotation of the first pulley 804 via the belt 806. The rotation of the first pulley 804 drives the rotation of the transmission rod 801. The rotation of the transmission rod 801 drives the rotation of the third bevel gear 803, which meshes with the fourth bevel gear 802. The rotation of the fourth bevel gear 802 drives the traction frame 6 to rotate in the opposite direction to the linkage frame 205. At the same time, the rotation of the traction frame 6 drives the rotation of the paint panel 7. The rotation of the paint panel 7 performs uniform painting on the circuit breaker drawer housings at multiple locations, thereby ensuring the effect and efficiency of the painting of the circuit breaker drawer housings.
