Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically a metal surface treatment conveyor. Background Technology

[0002] In the process of surface treatment of metal materials (such as spraying, electroplating, anodizing, phosphating, etc.), it is usually necessary to transport the workpiece to different processing stations to complete processes such as cleaning, chemical treatment, drying, spraying or curing.

[0003] However, existing metal surface treatment conveyor racks have the following problems during use: traditional suspended conveyor lines have a large footprint, are inconvenient to move, and have high maintenance costs. In addition, they are prone to deviation during the conveying process, resulting in insufficient stability and uneven surface treatment. Utility Model Content

[0004] The purpose of this invention is to provide a metal surface treatment conveyor to solve the related problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a metal surface treatment conveying frame, including an annular conveying platform frame, a transverse plate, and a positioning frame. The positioning frame is provided with the annular conveying platform frame via a longitudinal slide rail. A cylinder is installed at the top of the positioning frame, and the output end of the cylinder is connected to the top of the annular conveying platform frame. A transverse plate is installed on the outer wall of the positioning frame, and a caster wheel is installed at the bottom of the transverse plate. A positioning mechanism for positioning the positioning frame is provided inside the transverse plate. A support rail is installed inside the annular conveying platform frame, and a connecting frame is installed inside the support rail. A transmission mechanism for moving the position of the connecting frame is provided inside the annular conveying platform frame. Positioning balls adapted to the support rail are installed on the outer wall of the connecting frame. A positioning buffer mechanism is provided inside the connecting frame. A connecting bracket is installed below the connecting frame.

[0006] As a preferred embodiment of the metal surface treatment conveying rack of this utility model, the positioning mechanism includes a positioning screw and a vacuum suction cup. The interior of the transverse plate is provided with a threaded groove, and the positioning screw is provided inside the threaded groove. The bottom end of the positioning screw is equipped with a vacuum suction cup, and a connecting pipe valve is provided above the vacuum suction cup.

[0007] As a preferred embodiment of the metal surface treatment conveying frame of this utility model, the transmission mechanism includes a sprocket and a motor. The inside of the annular conveying platform frame is equipped with a rotating shaft through a bearing, and a sprocket is installed on the outer wall of the rotating shaft. The outer wall of the sprocket is fitted with a transmission chain that is connected to the connecting frame.

[0008] As a preferred embodiment of the metal surface treatment conveyor frame of this utility model, a motor is provided at the bottom of the annular conveyor platform frame, and the output end of the motor is connected to one end of the rotating shaft through a coupling.

[0009] As a preferred embodiment of the metal surface treatment conveying frame of this utility model, the positioning buffer mechanism includes a positioning track and a movable groove. The annular conveying platform frame is provided with a positioning track inside. The connecting frame is provided with a movable groove inside, and a T-shaped frame is provided inside the movable groove. A fixed frame is installed at the bottom of the T-shaped frame, and a roller adapted to the positioning track is installed inside the fixed frame through a bearing.

[0010] As a preferred embodiment of the metal surface treatment conveying frame of this utility model, the outer wall of the T-shaped frame is fitted with a spring that is connected to the inner wall of the movable groove.

[0011] As a preferred embodiment of the metal surface treatment conveyor frame of this utility model, the outer wall of the T-shaped frame is fitted with a damping block to improve the buffering effect and rub against the inner wall of the movable groove.

[0012] The beneficial effects of this utility model of a metal surface treatment conveyor frame are as follows:

[0013] 1. This utility model uses a starting motor to drive the rotating shaft to rotate, which in turn drives the sprocket to rotate. The sprocket then drives the connecting frame to slide within the positioning track via a transmission chain. At the same time, the positioning balls slide on the support track. This structure facilitates the transmission electroplating of multiple connecting frames, provides stable conveying, and results in a relatively uniform surface treatment.

[0014] 2. This utility model uses omnidirectional wheels to move the circular conveyor platform frame to a position above the electroplating tank. The wheels are then locked. Next, the positioning screw is rotated to engage with the interior of the transverse plate, causing the positioning screw to move the vacuum suction cup downwards until it is in contact with the ground. Then, a vacuum pump is inserted into the connecting pipe valve to extract air from the vacuum suction cup, creating negative pressure that tightly adheres to the ground, facilitating the fixation of the circular conveyor platform frame.

[0015] 3. This utility model solves the problem of easy deviation when moving at corners, resulting in insufficient stability and uneven metal surface treatment. By moving the roller position through the connecting frame, the roller compresses the spring inward, and the spring is tightened. When moving to a stable lateral section, the roller is put back into place by the elastic force of the spring and fits against the positioning track. This structure can transport stably and the surface treatment is more uniform. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1, as Figure 1-2As shown, this utility model provides a technical solution: a metal surface treatment conveyor frame, including an annular conveyor platform frame 1, a transverse plate 2, and a positioning frame 21. The positioning frame 21 is connected to the annular conveyor platform frame 1 via a longitudinal slide rail. A cylinder 22 is installed at the top of the positioning frame 21, and the output end of the cylinder 22 is connected to the top of the annular conveyor platform frame 1. The transverse plate 2 is installed on the outer wall of the positioning frame 21, and a caster wheel 3 is installed at the bottom of the transverse plate 2. A positioning mechanism for positioning the positioning frame 21 is provided inside the transverse plate 2. The positioning mechanism includes a positioning screw 4 and a vacuum suction cup 5. The interior of the transverse plate 2 is open. The device has a threaded groove, and a positioning screw 4 is installed inside the threaded groove. A vacuum suction cup 5 is installed at the bottom end of the positioning screw 4, and a connecting pipe valve 6 is installed above the vacuum suction cup 5. By pushing the universal wheel 3, the ring conveyor platform frame 1 is moved to the position above the electroplating tank. At this time, the universal wheel 3 is locked. Then, the positioning screw 4 is rotated to mesh with the inside of the transverse plate 2, thereby the positioning screw 4 moves the vacuum suction cup 5 downward to fit with the ground. Then, a vacuum pump is inserted into the connecting pipe valve 6 to extract the air from the vacuum suction cup 5, generating negative pressure to fit tightly with the ground, which facilitates the fixation of the ring conveyor platform frame 1.

[0024] Example 2, as Figure 1-5 As shown, this utility model provides a technical solution: a metal surface treatment conveyor frame, including a ring conveyor platform frame 1 with a support rail 7 installed inside, and a connecting frame 8 arranged inside the support rail 7. The ring conveyor platform frame 1 is equipped with a transmission mechanism for moving the position of the connecting frame 8. The transmission mechanism includes a sprocket 11 and a motor 12. A rotating shaft 13 is installed inside the ring conveyor platform frame 1 through a bearing, and a sprocket 11 is installed on the outer wall of the rotating shaft 13. A transmission chain 10 connected to the connecting frame 8 is sleeved on the outer wall of the sprocket 11. A motor 12 is arranged at the bottom end of the ring conveyor platform frame 1, and the output end of the motor 12 is connected to one end of the rotating shaft 13 through a coupling. By starting the motor 12, the rotating shaft 13 is driven to rotate, thereby the rotating shaft 13 drives the sprocket 11 to rotate. In turn, the sprocket 11 drives the connecting frame 8 to slide in the positioning rail 15 through the transmission chain 10. At the same time, the positioning ball 9 slides on the support rail 7. This structure facilitates the transmission electroplating of multiple sets of connecting frames 8 and improves the electroplating effect.

[0025] Example 3, as Figure 1-5As shown, this utility model provides a technical solution: a metal surface treatment conveyor frame, including a connecting frame 8 with positioning balls 9 adapted to the supporting rail 7 installed on its outer wall, a positioning buffer mechanism inside the connecting frame 8, and a connecting bracket 14 installed below the connecting frame 8. The positioning buffer mechanism includes a positioning rail 15 and a movable groove 16. The annular conveyor platform frame 1 has a positioning rail 15 inside, and a movable groove 16 is opened inside the connecting frame 8. A T-shaped frame 18 is installed inside the movable groove 16, and a fixed frame 17 is installed at the bottom of the T-shaped frame 18. A roller 20 adapted to the positioning rail 15 is installed inside the fixed frame 17 through a bearing. A spring 19 connected to the inner wall of the movable groove 16 is sleeved on the outer wall of the T-shaped frame 18. The outer wall of the T-shaped frame 18 is provided with a mechanism to improve the buffering performance and connect with the inner wall of the movable groove 16. The damping block connected to the wall slides on the positioning track 15 via the roller 20 at the connecting frame 8. Since the position of the annular conveyor platform frame 1 is aligned with the electroplating tank, the electroplating tank has an arc-shaped corner. The roller 20 is moved by the connecting frame 8, and the roller 20 compresses the spring 19 inward, causing the spring 19 to tighten. When it moves to a stable transverse section, the roller 20 returns to its original position against the positioning track 15 under the elastic force of the spring 19. This structure, with the damping block at the T-shaped frame 18, can improve the buffering performance of the spring 19 when it returns to its original position, which helps to solve the problem of deviation and instability when moving at corners. Existing technology uses single-sided rear support sliding, which cannot meet the stability requirements, resulting in insufficient stability, easy damage, and long-term maintenance by operators. This structure can transport stably and has a more uniform surface treatment.

[0026] Working principle: First, connect the external power supply. The operator can hang the metal rack to be processed on the connecting rack 14. Then, the operator pushes the caster 3 to move the annular conveyor platform frame 1 to the position above the electroplating tank. At this time, lock the caster 3. Then, rotate the positioning screw 4 to engage with the inside of the transverse plate 2. The positioning screw 4 drives the vacuum suction cup 5 to move downwards until it is in contact with the ground. Then, use a vacuum pump inserted into the connecting pipe valve 6 to extract the air from the vacuum suction cup 5, creating negative pressure to tightly adhere to the ground. After the position of the annular conveyor platform frame 1 is fixed in the electroplating tank position, the operator can start the cylinder 22 to push the annular conveyor platform frame 1 downwards in the positioning frame 21 into the electroplating tank. Start the motor 12 to drive the rotating shaft 13 to rotate. The rotating shaft 13 drives the sprocket 11 to rotate, and then... The sprocket 11 drives the connecting frame 8 to slide within the positioning track 15 via the transmission chain 10, while the positioning ball 9 slides on the support track 7. This structure facilitates the transmission electroplating of multiple sets of connecting frames 8, improving the electroplating effect. Since the position of the annular conveyor platform frame 1 is aligned with the electroplating tank, the electroplating tank has an arc-shaped corner. The connecting frame 8 drives the position of the roller 20 to move, and the roller 20 compresses the spring 19 inward, causing the spring 19 to tighten. When it moves to a stable lateral section, the roller 20 is repositioned and fits against the positioning track 15 under the elastic force of the spring 19. This structure solves the difficulty of moving at corners. Existing technology uses single-sided rear support sliding, which cannot meet the stability requirements, resulting in insufficient stability, easy damage, and the need for long-term maintenance by operators.

Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
