Description

Technical Field

[0001] This utility model relates to the field of dehumidification equipment technology, specifically to a rotary dehumidification equipment for spraying plastic products. Background Technology

[0002] To prevent moisture from affecting the coating quality, dehumidification is performed before spraying plastic products.

[0003] A search revealed that patent CN211526959U discloses a rotary dehumidification device for spraying plastic products. This device, through the cooperation of a hot air blower and an air supply pipe, can dry the raw materials in the dehumidification chamber. The cooperation of a second drive motor, cam, rollers, springs, and push rods enables the dehumidification chamber to circulate left and right, ensuring more thorough heating of the raw materials and improving dehumidification efficiency for better drying. The pulleys and first sliding groove allow the hot air blower and water tank to circulate left and right along with the dehumidification chamber. The water tank and outlet pipe allow for the return and storage of water during processing, saving water resources and avoiding waste.

[0004] However, the above-mentioned equipment can only dehumidify the raw materials of plastic products.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a dehumidification device for rotary plastic product spraying.

[0027] This utility model provides, for example Figure 1-3 The rotary dehumidification device for spraying plastic products shown includes a support frame 1, a drying cylinder 2 fixedly mounted on the top of the support frame 1, two symmetrically arranged electric cylinders 3 fixedly mounted on the bottom of the upper end of the support frame 1, the piston rod ends of the two electric cylinders 3 both protrude from the support frame 1 and are fixedly mounted on a cylinder cover 4 through a connecting rod 20, the cylinder cover 4 is sleeved with the drying cylinder 2, a sealing ring 18 is fixedly mounted on the upper end of the cylinder cover 4, an air guide pipe 5 is rotatably mounted on the top of the support frame 1, a hot air blower 6 is fixedly mounted on the bottom of the upper end of the support frame 1, an air outlet pipe 7 is connected to the air outlet end of the hot air blower 6, the upper end of the air outlet pipe 7 is rotatably mounted inside the lower end of the air guide pipe 5, the air outlet pipe 7 and the air guide pipe 5 are connected by a sealed bearing, the pipe wall of the air guide pipe 5 has multiple ventilation holes, and the inner wall of each of the multiple ventilation holes is fixedly embedded with a filter screen 19;

[0028] The air duct 5 has multiple support plates 8 fixedly installed on its wall. The bottom of the support plate 8 is rotatably provided with a vertical rod 9. The lower end of the vertical rod 9 is provided with a clamping mechanism. The clamping mechanism includes two symmetrically arranged fixed rods 15. The fixed rods 15 are fixedly connected to the lower end of the outer wall of the vertical rod 9, and the rod wall is rotatably fitted with a clamping plate 16. The rod wall of the fixed rod 15 is fitted with a torsion spring 17. The two ends of the torsion spring 17 are fixedly connected to the fixed rod 15 and the clamping plate 16 respectively.

[0029] Before spraying the plastic products, multiple plastic products are placed in the drying cylinder 2, and the two clamping plates 16 are pushed, causing the clamping plates 16 to rotate around the fixed rod 15 and push the torsion spring 17. At this time, the plastic products are placed between the two clamping plates 16, and the clamping plates 16 are released. The torsion force of the torsion spring 17 returns, causing the two clamping plates 16 to clamp the plastic products. After multiple plastic parts are installed, the electric cylinder 3 is pulled back, and the cylinder cover 4 is placed on the outside of the drying cylinder 2 through the connecting rod 20. The sealing ring 18 ensures the seal between the cylinder cover 4 and the drying cylinder 2. Then the hot air blower 6 is started, so that hot air enters the drying cylinder 2 through the air outlet 7 and the air guide 5. The hot air is filtered by the filter screen 19 and comes into contact with the plastic parts to dry and dehumidify the plastic surface. At the same time, the air guide 5 rotates and drives multiple vertical rods 9 to rotate, so that the plastic parts rotate and all parts of their outer side come into contact with the hot air, improving the drying and dehumidification effect of the plastic parts and ensuring the quality of subsequent spraying.

[0030] To improve the drying effect by ensuring stable rotation of the plastic part during the drying process, such as... Figure 1-2 As shown, the first spur gear 10 is fixedly sleeved on the walls of multiple vertical rods 9, and multiple internal gear rings 11 are fixedly installed on the inner wall of the drying cylinder 2. The first spur gear 10 and the internal gear rings 11 are configured to cooperate.

[0031] A motor 12 is fixedly installed at the bottom of the upper end of the support frame 1. A second spur gear 13 is fixedly installed at the output end of the motor 12. A third spur gear 14 is fixedly installed at the lower end of the air duct 5. The second spur gear 13 and the third spur gear 14 are configured to cooperate.

[0032] During the hot air circulation process, the motor 12 starts, and the air duct 5 can rotate through the meshing of the second sprocket 13 and the third sprocket 14. When the air duct 5 rotates, the support plate 8 starts to rotate. At this time, under the meshing of the first sprocket 10 and the internal gear ring 11, the vertical rod 9 drives the plastic part to rotate, which allows the hot air to flow out through the ventilation hole and make effective contact with all parts of the plastic part surface, thus improving the drying and dehumidification effect of the plastic part surface.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
