Description

Technical Field

[0001] This utility model relates to the field of glass railing production and processing technology, specifically a spraying machine for glass railing processing. Background Technology

[0002] Glass railings, also known as glass balustrades or glass handrails, are a type of railing system primarily made of transparent safety glass. They typically consist of large panes of glass fixed to a base on the ground, with stainless steel, copper, or wooden handrails installed between the glass panes. This design not only provides transparency but also blends seamlessly with the surrounding environment, creating a simple yet sophisticated visual effect. To extend the lifespan of glass railings, a protective coating is often applied to the handrail surface during manufacturing to prevent corrosion. Currently, the surface coating of glass railings is mostly done manually. The glass railings are hung in rows on the spraying rack using hooks. Then, a person manually holds a spray gun and sprays both sides of the rows of glass railings in turn to achieve surface coating. Traditional glass railing surface coating is done manually by holding a spray gun. Manual spraying requires spraying both sides of the rows of glass railings in turn, which cannot be done continuously. The spraying efficiency is low, and the long interval between spraying on both sides of the glass railings can easily lead to delamination and color difference at the joints of the glass railings, resulting in poor coating quality. To address this, we propose a spraying machine for glass railing processing. Utility Model Content

It also includes clamping plates 38 and motors 39. The clamping plates 38 are rotatably connected to the inner end of the sliding frame 31. Four vertically adjacent clamping plates 38 are arranged in a cross shape. A conductive slip ring 4 is provided in the middle of the outer surface of the mounting shaft 2. A contact head 5 is provided in the middle of the interior of the spraying frame 1. The lower end of the contact head 5 is in contact with the outer surface of the conductive slip ring 4. The input end of the contact head 5 is electrically connected to the output end of the microcontroller 11, and the input end of the conductive slip ring 4 is electrically connected to the output end of the contact head 5. Motors 39 are all located at the front end of the sliding frame 31. The input end of each motor 39 is electrically connected to the output end of the conductive slip ring 4. The rear end of the output end of each motor 39 is fixedly connected to the front end of the vertically adjacent clamping plates 38, providing a rotational effect for the uniform spraying of the glass railing. A spraying mechanism 3 is also provided.By adjusting and quickly fixing glass railings of different sizes, and after uniformly spraying the surface of the glass railings, the system can automatically and quickly unload the material, achieving continuous and uniform spraying operations and improving the spraying efficiency and quality of the glass railings.

[0024] The working principle of the spraying machine for glass railing processing provided by this utility model is as follows: When spraying the surface of the glass railing, an external feeding conveyor belt is provided on the left side of the equipment, and an external discharging conveyor belt is provided on the right side of the equipment. First, adjust the position of the sliding frame 31 according to the size of the glass railing. The microcontroller 11 controls the electric push rod 36 to work. After the telescopic end of the electric push rod 36 retracts to the appropriate position, the handwheel is rotated to drive the limit ring 34 to move. The limit groove 35 squeezes the ball head 33, which drives the moving blocks 32 on the front and rear sides to move inward. When the protrusion on the moving block 32 contacts the inner wall of the groove, the two sliding frames 31 also move inward synchronously until the inner end of the sliding frame 31 is in contact with the end of the electric push rod 36. The glass railings are then placed sequentially on the external feeding conveyor belt. When the external feeding conveyor belt moves the glass railings between the two clamping pieces 38 on the left side, the ball head 33 is located at the connection point of the two vertically adjacent limiting grooves 35. The microcontroller 11 controls the motor 310 to operate, which in turn drives the mounting shaft 2 and the sliding frame 31 to rotate. The moving block 32 and the ball head 33 also rotate accordingly. The limiting ring 34 and the limiting groove 35 are fixed by the spray frame 1. As the ball head 33 rotates, the contour of the upper limiting groove 35 presses the ball head 33 inward. When the ball head 33 leaves the inclined groove on the left side of the upper limiting groove 35, the two clamping pieces 38 are just aligned with the two sides of the glass railing. The ends fit together to clamp the glass railing. When the sliding frame 31 rotates 90 degrees, the glass railing and the spray head 7 are vertically adjacent. The spray head 7 sprays protective coating onto the surface of the glass railing. At the same time, the microcontroller 11 controls motors 39 and 9. Motor 39 drives the front clamping plate 38 to rotate, and the glass railing rotates accordingly. Motor 9 drives the lead screw 8 to rotate, and the lead screw 8 drives the slider 6 and the spray head 7 to reciprocate back and forth. The movement distance of the slider 6 and the spray head 7 is equal to the size of the glass railing. At this time, the spray head 7 moves back and forth evenly to spray the protective coating onto the surface of the glass railing. The glass railing also rotates around its own axis, which allows the surface of the glass railing to be sprayed with protective coating. For more uniform coating, after the glass railing is coated, motor 310 starts, and mounting shaft 2 and sliding frame 31 rotate to the right again. At this time, the next glass railing is just moved into place by the external feeding conveyor belt. The next set of clamping plates 38 clamps the next glass railing. When the next glass railing is vertically adjacent to the spray head 7, the ball head 33 that clamps the previous glass railing moves to the inclined groove on the right side of the upper limiting groove 35. At this time, the ball head 33 drives the moving block 32 to move outward a short distance. The corresponding clamping plate 38 separates from the end of the glass railing. The glass railing loses its clamping effect and falls onto the external discharge conveyor belt to be transported to the next process. This process is repeated.

[0025] It is worth noting that the microcontroller 11 disclosed in the above embodiments is a microcontroller, the electric actuator 36 is an NKLA36 electric actuator, the first motor 39 is a 2BLD10-24GN-20S motor, the second motor 9 is a DKM motor, and the third motor 10 is a Y280M-2 motor. The microcontroller 11 controls the operation of the electric actuator 36, the first motor 39, the second motor 9, and the third motor 10 using methods commonly used in the prior art.
