[0002] The coating technology mainly uses a coating machine to coat small bolts. The bolts to be coated on the surface are placed in a workpiece basket through a loading mechanism, and then the workpiece basket is placed in a dipping tank for dip coating. The excess water or liquid is quickly and effectively dried, and finally the workpiece basket is unloaded from the unloading mechanism through a conveying device.

[0003] In the existing technology, there is a lack of a pre-heating device before the coating operation of small bolts, which results in the surface of the small bolts not being able to dry quickly during coating, resulting in overlapping in the subsequent dipping process; secondly, during dipping, since the acid and alkali resistant solution will produce precipitation when standing, the purity of the dipping liquid at different depths is different, which makes the dipping quality of the small bolts inconsistent, affecting production; furthermore, in the process of centrifugal drying and hot air drying of the bolts, the liquid retained by gravity and splashed by centrifugal force has no collection function, resulting in waste of resources. Summary of the invention

[0004] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and to propose a planetary coating machine to solve the problems existing in the prior art planetary coating machine, such as lack of a preheating device, precipitation of the coating liquid during the coating process resulting in uneven coating quality of small bolts, and lack of a coating liquid collecting device.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The present invention sets a preheating box, a heating net, a containing basket and a temperature sensor. When small bolts are added to the containing basket, the heating net is started to preheat the small bolts inside the preheating box. When the temperature sensor detects that the temperature inside the containing basket is higher than the set value, the temperature sensor sends a signal to the single-chip microcomputer, and the single-chip microcomputer controls the mechanical claw control system to work. Then the mechanical claw grabs the containing basket and moves the containing basket to the dipping box through the slide rail to carry out the next process, which effectively solves the problem of lack of preheating device;

[0014] 2. The present invention provides a stirring shaft, a gear plate, a sun gear, a planetary gear and a small rotating motor. When the small bolts are preheated and dipped, the basket is first placed in the dipping box, and then the small rotating motor is started. The output end of the small rotating motor drives the sun gear to rotate. Since the sun gear, the planetary gear and the gear plate are meshed and connected with each other, the planetary gear rotates while revolving around the sun gear, so as to fully stir the dipping liquid in the dipping box, avoid precipitation of the liquid affecting the dipping process, and at the same time, the preheated small bolts can avoid the phenomenon of overlapping due to the viscosity of the liquid during dipping, so that the dipping process is more perfect, and effectively solves the problem of uneven dipping quality of small bolts caused by precipitation of the dipping liquid during the dipping process;

When the spin-drying process is carried out, the mechanical claw controls the coating-finished basket to be dried and puts it into the spin-drying box, and then closes the box door. Under the action of gravity, a part of the liquid flows directly from the bottom of the basket to the water outlet, and the medium-sized rotating motor is started to drive the spin-drying box to rotate. The liquid on the surface of the small bolt is dried by the centrifugal force, and the splashed liquid finally flows into the water pipe through the water outlet. The filter screen filters the impurities in the liquid to prevent pollution when the liquid is subsequently recycled. The liquid in the water pipe flows to the liquid box for temporary storage. When the liquid box is full, the water pump is started, and the water pump pumps the liquid in the liquid box through the water inlet pipe and the water outlet pipe to the inside of the dipping box, thereby avoiding the waste of resources, achieving the purpose of environmental protection operation, and effectively solving the problem of lack of dipping liquid collection device.

[0025] Please refer to Figure 1 The mechanical claw 3 is connected to the external control system, and the feeding pipe 9 is connected to the external feeding system, so that the external control system can control the mechanical claw 3 and the external feeding system can control the feeding of the feeding pipe 9. The pressure sensor 7 is electrically connected to the feeding control system through the single chip microcomputer, and the temperature sensor 8 is electrically connected to the control system of the mechanical claw 3 through the single chip microcomputer, so that the pressure sensor 7 can control the feeding pipe 9 and the temperature sensor 8 can control the mechanical claw 3.

[0026] Please refer to Figure 2-3 The number of planetary gears 17 is four, and the four planetary gears 17 are equidistantly distributed on the outer wall of the sun gear 16. The sun gear 16, the gear plate 12, and the planetary gears 17 are connected by teeth meshing, so that the four planetary gears 17 rotate around the sun gear 16 to achieve a stirring effect. The output end of the small rotating motor 18 is rotatably connected to the sun gear 16 through a coupling, so that the output end of the small rotating motor 18 drives the sun gear 16 to rotate.

[0027] Please refer to Figure 4 A filter screen 20 is fixed to the inner wall of the water outlet 19 , and bolts are provided at the connection between the filter screen 20 and the water outlet 19 , and the filter screen 20 is fixedly connected to the water outlet 19 by the bolts, so as to facilitate the installation and fixation of the filter screen 20 .

[0028] Working principle: First, the feed pipe 9 is controlled by the external feeding system, and a large number of small bolts flow into the basket 6 from the feed pipe 9. When the pressure sensor 7 detects that the pressure value is higher than the set value, the pressure sensor 7 sends a signal to the single-chip microcomputer, and the single-chip microcomputer controls the feeding system to stop feeding. When small bolts are added to the basket 6, the heating net 5 is started to preheat the small bolts inside the preheating box 4. When the temperature sensor 8 detects that the temperature inside the basket 6 is higher than the set value, the temperature sensor 8 sends a signal to the single-chip microcomputer, and the single-chip microcomputer controls the feeding system to stop feeding. The mechanical claw 3 controls the system to work, and then the mechanical claw 3 grabs the basket 6 and moves the basket 6 to the dipping box 10 through the slide rail 2 to carry out the next process. When the small bolts are preheated and dipped, the basket 6 is first placed in the dipping box 10, and then the small rotating motor 18 is started. The output end of the small rotating motor 18 drives the sun gear 16 to rotate. Since the sun gear 16, the planetary gear 17 and the gear plate 12 are meshed and connected with each other, the planetary gear 17 rotates while revolving around the sun gear 16, so that the planetary gear 17 drives the stirring shaft 11 fully stirs the dipping liquid inside the dipping box 10, avoiding the precipitation of the liquid affecting the dipping process. At the same time, the preheated small bolts can avoid the phenomenon of overlapping due to the viscosity of the liquid during dipping, making the dipping process more perfect. When the spin-drying process is performed, the mechanical claw 3 controls the dipped basket 6 to be dried and puts it into the spin-drying box 13, and then closes the box door 14. Under the action of gravity, a part of the liquid flows directly from the bottom of the basket 6 to the drain 19, and the medium-sized rotating motor 15 is started, and the medium-sized rotating motor 15 drives the spin-drying box 1 3 rotates, and the liquid on the surface of the small bolt is dried by the centrifugal force. The splashed liquid finally flows into the water pipe through the drain port 19. The filter screen 20 filters the impurities in the liquid to prevent pollution when the liquid is recycled in the subsequent use. The liquid in the water pipe 21 flows to the liquid tank 22 for temporary storage. When the liquid tank 22 is full, the water pump 23 is started, and the water pump 23 pumps the liquid in the liquid tank 22 through the water outlet pipe 25 through the water inlet pipe 24 to the inside of the dipping box 10, thereby avoiding the waste of resources and achieving the purpose of environmental protection.
