Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coating, in particular to a coating turntable rack. Background Art
[0002] At present, in the negative ion coating technology, the ion emission end of a negative ion generator is communicated with the nozzle of a coating device, so that the negative ions generated by the negative ion generator can directly enter the nozzle. The negative ions contact with the atomized coating liquid, so that the atomized coating liquid ejected from the nozzle carries negative ions. After the coating liquid is ejected from the nozzle, it can quickly adhere to the original sheet, reducing the dissipation of the coating liquid in the air.
[0003] In the existing negative ion coating equipment, a coating turntable rack is used. The products are placed on the turntable rack, and the products are coated while following the rotation of the turntable rack. However, it is found in the actual use process that: during the rotation of the turntable rack, the products cannot be accurately aligned with the coating spray, and it is easy to appear skewed, resulting in incomplete local coating on the surface of the products, affecting the use quality of the products. For this reason, a coating turntable rack is proposed. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the problem that the existing coating turntable rack cannot accurately rotate and coat products, and a coating turntable rack is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0006] A coating turntable rack includes a base. Above the base, there is a turntable. At the center of the bottom of the turntable, a rotating shaft is fixedly arranged, and the lower end of the rotating shaft is fixedly connected to the center of the top of the base. At the edge of the upper surface of the turntable, a plurality of evenly distributed coating plates are fixedly arranged; on the top of the base and on one side of the rotating shaft, a motor is fixedly arranged. The output shaft of the motor is fixedly provided with a sector gear. On the shaft wall of the rotating shaft, a circular gear is fixedly arranged, and the circular gear can be meshed with the sector gear; on the top of the base and on one side of the motor, a control box is fixedly arranged. A stop switch is installed on the side wall of the control box. An extrusion head elastically contacting the stop switch is arranged on the top of the sector gear. The stop switch is electrically connected to the motor through the control box.
[0007] Preferably, a fixed seat is fixedly arranged on the top of the sector gear. Inside the fixed seat, a slide bar is horizontally arranged. One end of the slide bar is fixedly connected to the extrusion head, and the other end of the slide bar is fixedly provided with a connecting block. A spring is sleeved on the rod wall of the slide bar, and both ends of the spring are fixedly connected to the fixed seat and the connecting block respectively.
[0008] Preferably, the extrusion head adopts a spherical structure, and the stop switch adopts a semi-circular structure.
[0009] Preferably, the number of the coating discs is four.
[0010] Preferably, the tooth distribution of the sector gear is 90°.
[0011] Preferably, a rotating shaft damping sleeve is fixedly arranged at the top of the base, and the lower end of the rotating shaft is inserted into the inside of the rotating shaft damping sleeve.
[0012] Preferably, mounting rings are fixedly arranged on both sides of the base.
[0013] Compared with the prior art, the present utility model provides a coating turntable, which has the following beneficial effects:
[0014] 1. For this coating turntable, through the provided motor, sector gear and circular gear, when the power supply of the motor is turned on, the motor can drive the sector gear to rotate, and the sector gear can drive the circular gear to rotate, so that the rotating shaft drives the turntable at the upper end to rotate, thereby rotating the product inside the coating disc to the lower part of the coating nozzle. During the rotation of the sector gear, the extrusion head will contact the stop switch. After the stop switch is triggered, the motor stops working through the control box. At this time, the continuous rotation of the sector gear is stopped, so that the rotation of the circular gear can be stopped, and the coating disc can be accurately rotated to the lower part of the coating nozzle.
[0015] 2. For this coating turntable, through the provided fixed seat, sliding rod, connecting block and spring, when the extrusion head contacts the stop switch, the sliding rod moves and stretches the spring through the connecting block. When the extrusion head separates from the stop switch, at this time, the elastic force of the spring makes the sliding rod drive the extrusion head to move and reset, facilitating the extrusion head to contact the stop switch again.
[0016] 3. For this coating turntable, through the rotating shaft damping sleeve arranged at the lower end of the rotating shaft, the rotating shaft damping sleeve can increase the frictional resistance of the rotating shaft. When the sector gear separates from the circular gear, the rotating shaft will not rotate continuously, ensuring the stability of the turntable and the coating disc.
[0017] The parts not involved in this device are the same as those in the prior art or can be implemented by using the prior art. The present utility model has a structure for automatically stopping the rotation of the turntable, enabling the coating disc to be accurately rotated to the lower part of the coating nozzle, improving the quality of negative ion coating of the product.

Specific implementation manner
[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.
[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.
[0024] Refer to Figures 1 - 3 , a coating turntable, including a base 1, a turntable 2 is provided above the base 1, a rotating shaft 3 is fixedly provided at the center of the bottom of the turntable 2, and the lower end of the rotating shaft 3 is fixedly connected to the center of the top of the base 1. Four evenly distributed coating disks 4 are fixedly provided at the edge of the upper surface of the turntable 2.

A sector gear 6 is fixedly provided on the output shaft of the motor 5. A circular gear 7 is fixedly provided on the shaft wall of the rotating shaft 3, and the circular gear 7 can be meshed with the sector gear 6. The tooth distribution of the sector gear 6 is 90°, which can ensure that the sector gear 6 drives the circular gear 7 to rotate 90°, and one of the coating disks 4 can just rotate to the lower part of the coating nozzle; a control box 8 is fixedly provided on the top of the base 1 and on one side of the motor 5. A stop switch 9 is installed on the side wall of the control box 8. An extrusion head 10 that contacts the stop switch 9 is elastically provided on the top of the sector gear 6. The extrusion head 10 adopts a spherical structure, and the stop switch 9 adopts a semi-circular structure. The stop switch 9 is electrically connected to the motor 5 through the control box 8.
[0025] When negative ion coating is required, the power supply of the motor 5 is turned on. The motor 5 can drive the sector gear 6 to rotate, and the sector gear 6 can drive the circular gear 7 to rotate, so that the rotating shaft 3 drives the turntable 2 at the upper end to rotate, thereby rotating the product inside the coating disk 4 to the lower part of the coating nozzle. Since the tooth distribution of the sector gear 6 is 90°, it can ensure that the sector gear 6 drives the circular gear 7 to rotate 90°, and one of the coating disks 4 can just rotate to the lower part of the coating nozzle. During the rotation of the sector gear 6, the extrusion head 10 will contact the stop switch 9. After the stop switch 9 is triggered, the motor 5 stops working through the control box 8. At this time, the continuous rotation of the sector gear 6 is stopped, so that the circular gear 7 can be stopped from rotating, and the coating disk 4 can be accurately rotated to the lower part of the coating nozzle, improving the quality of negative ion coating of the product.
[0026] Refer to Figure 3 , a fixing seat 11 is fixedly provided at the top of the sector gear 6. A slide bar 12 is horizontally provided inside the fixing seat 11.

A spring 14 is sleeved on the rod wall of the slide bar 12, and both ends of the spring 14 are fixedly connected to the fixing seat 11 and the connecting block 13 respectively. When the extrusion head 10 contacts the stop switch 9, the slide bar 12 moves and stretches the spring 14 through the connecting block 13. When the extrusion head 10 separates from the stop switch 9, the elastic force of the spring 14 at this time makes the slide bar 12 drive the extrusion head 10 to move and reset, facilitating the extrusion head 10 to contact the stop switch 9 again and stop the motor 5 from working.
[0027] Refer to Figure 1 , a rotating shaft damping sleeve 15 is fixedly provided at the top of the base 1. The lower end of the rotating shaft 3 is inserted into the inside of the rotating shaft damping sleeve 15.
