Description

Technical Field

[0001] The invention relates to the technical field of plastic product processing, in particular to an antistatic coating spraying device for producing plastic product containers. Background Art

[0002] Plastic containers are made of plastic materials. They are light, cheap and not easy to break. They are widely used in industrial production. However, plastic containers also have their own disadvantages. One of the more prominent ones is that due to the characteristics of the materials they are made of, static electricity is easily generated during the friction during transportation. When transporting some special chemicals, there is a risk of explosion. Therefore, for such plastic containers with special uses, they usually need to be treated with an anti-static coating after production.

[0003] The traditional method is to suspend and move the plastic container in the spraying workshop using a suspension moving system, so that the container passes through the spraying workshop, is sprayed at multiple angles by multiple spray heads in the workshop, and then passes through the baking workshop for baking and shaping. This cycle repeats 1-3 times, and multiple spraying and baking are performed to finally form an antistatic coating on the surface of the container. However, the existing spraying technology has the following defects: 1. The spraying suspension system needs to be shut down when loading and unloading materials in and out of the workshop, which makes the entire spraying process discontinuous. Usually, it is processed in batches according to the scale of the workshop, which is inefficient and easily leads to differences between each batch of products; 2. In the spraying and baking workshop, since the container usually has a cylindrical outer wall, the nozzle and baking hot air diverge linearly, which leads to uneven spraying and baking due to angle and distance when working on the surface of round parts; 3. The hanging system usually uses a hook to hook the handle of the container or hook it inside the container. The fixed position is not fixed, which causes a certain tilt of the container as a whole, further leading to uneven spraying, and the hanging and fixing effect is not reliable. It is easy to fall under the action of airflow during paint spraying and baking, affecting the entire spraying operation; In order to solve the above problems, an antistatic coating spraying equipment for producing plastic product containers is provided. Summary of the invention

The electric heating pipe 162 adopts a numerical control switch to accurately control the temperature.

[0036] Working principle: When the device is in use, the container is fixed by the container hanging member 3; then the fixed container is hung in the loading support member 243 from one side of the inlet and outlet port 22 through the container hanging member 3, and the connecting tube 32 is pushed inward from the opening of the U-shaped groove 2432 so that the connecting tube 32 and the outer inclined surfaces of the two groups of anti-detachment blocks 2433 are abutted, so that the two groups of anti-detachment blocks 2433 move to the opposite side, so that the anti-detachment spring 2434 is compressed, and when the connecting tube 32 enters the U-shaped groove 2432, the two groups of anti-detachment blocks 2433 move outward and block the opening of the U-shaped groove 2432, and then the container hanging member 3 is released, and under the action of gravity, the gear 34 is connected with the top of the single-opening U-shaped clamp 2431; At this time, the second servo motor 23 is started to move the drag chain 122 in the loading and unloading hanging rail 241, and the material is moved to the bottom of the front side of the circular hanging rail 121 through the loading support 243, and then the second servo motor 23 stops. At this time, the first servo motor 123 is started to drive the drag chain 122 inside the circular hanging rail 121 to move, thereby moving the hanging member 125. When the hanging member 125 moves above the loading support 243, the convex clamping seat 1252 is opposite to the convex connecting block 31. At this time, the hanging member 125 continues to move forward, so that the convex clamping seat 1252 is sleeved on the outer surface of the convex connecting block 31. At this time, the first strong magnet 1254 and the second strong magnet 310 are adsorbed and fixed, and at the same time, the ball head clamping column 38 enters the clamping hole 1255 to complete the connection. Then, as the suspension member 125 continues to move forward, the adsorption force of the first strong magnet 1254 and the second strong magnet 310 plus the friction provided by the cooperation between the ball head clamping column 38 and the clamping hole 1255 is greater than the resistance of the two sets of anti-detachment blocks 2433 to the connecting tube 32. At this time, the two sets of anti-detachment blocks 2433 are squeezed to move to both sides, so that the connecting tube 32 is moved out of the U-shaped groove 2432, and the material is transferred from the loading and unloading hanging rail 241 to the circular hanging rail 121. Then the suspension 125 carries the plastic container to move inward, at which time the dryer 16 and the spray rack 19 are started, and the plastic container first passes through a group of spray racks 19, which spray directly onto the residual material recovery part 17, and when the plastic container reaches the spray rack 19 position, the gear 34 just contacts the rack 128, and as the suspension 125 continues to move forward, the gear 34 drives the plastic container to rotate through the connecting pipe 32 for uniform spraying, and the rotary sealing joint 33 rotates at this time, and immediately enters the dryer 16 position after completing one spraying, and hot air is blown through the dryer 16, while the plastic container continues to rotate, and then passes through the next group of spray racks 19, and the specific number of spray racks 19 and dryers 16 is designed according to the workshop size and the actual spraying requirements, and it is clear that the entire spraying and drying process is continuous and uninterrupted, and starts with spraying and ends with drying, and performs continuous alternating operations, and finally forms a uniform antistatic coating on the outer surface of the plastic container; After the antistatic coating of the plastic container is sprayed and dried, the plastic container follows the suspension part 125 to move to the other side of the loading and unloading hanging rail 241. At this time, the single-opening U-shaped clamp 2431 is opposite to the connecting pipe 32. As the suspension part 125 moves, the connecting pipe 32 enters the U-shaped groove 2432. Then the suspension part 125 continues to move, and the single-opening U-shaped clamp 2431 has only one side opening. At this time, the connecting pipe 32 is blocked and cannot move, so that the convex connecting block 31 is pulled out from the through-slot 1253 to complete the separation, so that the plastic container and the container suspension part 3 are transferred from the circular suspension rail 121 to the loading and unloading hanging rail 241, and then the second servo motor 23 is started, so that the processed plastic container moves to the position of the inlet and outlet port 22 on the other side. At this time, the operator pulls the container suspension part 3 and the container out of the U-shaped groove 2432 synchronously, and then deflates the air through the valve 37 to separate the container from the container suspension part 3, and the container suspension part 3 moves to the opposite side for loading and use; Thus, a complete cycle operation is formed, the container hanger 3 is continuously installed on the new container, and then hung on the loading support 243. The loading support 243 is accurately moved by the second servo motor 23, so that the two groups of single-opening U-shaped clips 2431 facing in opposite directions are located on the moving path of the suspension part 125. The single-opening U-shaped clip 2431 with the opening facing the suspension part 125 forks down the container that has been sprayed on the suspension part 125, and the single-opening U-shaped clip 2431 with the opening facing away from the suspension part 125 hangs a new container on the suspension part 125, so that the suspension part 125 can move in an uninterrupted cycle at the bottom of the circular suspension rail 121 for the spraying operation. The spraying process is continuous and uninterrupted, with high efficiency and convenient loading and unloading.
