Description

Technical Field

[0001] This utility model relates to the technical field of thermoforming sheet conveying equipment, and in particular to an anti-static thermoforming sheet conveying device. Background Technology

[0002] Vacuum forming sheets are a type of plastic processing material. The main principle is to heat a flat, rigid plastic sheet until it softens, then use a vacuum to adhere it to the surface of a mold. After cooling, it takes shape and is widely used in industries such as plastic packaging, lighting, advertising, and decoration. When the vacuum forming sheet enters the next production stage, it needs to be conveyed using conveyor rollers.

[0003] However, when the thermoformed sheet comes into rapid contact with the conveyor roller, it is susceptible to both triboelectric charging and static electricity generation upon contact and separation. During this process, the friction between the two materials causes electrons to transfer from one object to the other, generating static electricity. This static electricity can cause the thermoformed sheet to attract dust from the air during transport, affecting product quality. Therefore, ensuring that the thermoformed sheet does not generate static electricity during transport is a pressing problem that needs to be solved in this technical field. Utility Model Content

[0024] Please see Figure 1-4An antistatic blister sheet conveying device includes a conveyor frame 1, a base plate 2 fixed to the bottom of the conveyor frame 1, and two antistatic liquid storage tanks 3 installed on the top of the base plate 2. The bottom wall of the inner cavity of the tanks 3 is equipped with a suction pump 11, which can draw the antistatic liquid inside the antistatic liquid storage tanks 3 and deliver it to the antistatic liquid adhesion tray 5. The outlet of the suction pump 11 is connected to a guide pipe 4. The top of the conveyor frame 1 is equipped with an inlet roller 6 and a conveyor roller 7. The middle of the conveyor frame 1 and near the conveyor roller 7 is equipped with an adjustable height antistatic liquid adhesion tray 5.

[0025] Please see Figure 2 In this embodiment, the guide pipe 4 is composed of an inlet pipe 401, a shaping pipe 402 and an outlet pipe 403. The inlet pipe 401 is connected to the outlet of the suction pump 11. The two ends of the shaping pipe 402 are connected to the inlet pipe 401 and the outlet pipe 403 respectively. The outlet of the outlet pipe 403 is placed in the antistatic liquid adhesion plate 5.

[0026] Specifically, the inlet pipe 401 is connected to the suction pump 11 and can deliver the antistatic liquid discharged by the suction pump 11. The shaping pipe 402 can be bent to a suitable angle and hooked onto the antistatic liquid adhesion plate 5 to maintain the overall stability of the guide pipe 4. The outlet pipe 403 is placed in the antistatic liquid adhesion plate 5 and is used to discharge the antistatic liquid.

[0027] Please see Figure 1 and Figure 2 and Figure 3 In this embodiment, height adjustment plates 501 are fixed on both the left and right sides of the antistatic liquid adhesion tray 5. The height adjustment plates 501 are placed in the height adjustment ports 8 opened on both the left and right sides of the conveyor frame 1. A cylinder 9 is installed on the inner bottom wall of the height adjustment port 8. The power output shaft at the top of the cylinder 9 is fixed at the center of the bottom surface of the height adjustment plate 501. Limiting rods 10 are fixed on both sides of the bottom of each height adjustment plate 501. The bottom of the limiting rods 10 is slidably connected to the limiting holes opened on the bottom wall of the height adjustment port 8. The depth of the limiting holes is greater than the length of the limiting rods 10.

[0028] Specifically, the height adjustment port 8 can limit the range of motion of the height adjustment plate 501, allowing it to move only vertically up and down, thus effectively limiting its movement and ensuring the stability of the height adjustment plate 501 and the antistatic liquid adhesion plate 5. The bottom of the height adjustment plate 501 has a limiting rod 10, which is movably inserted into the limiting hole. This limiting rod 10 can provide auxiliary limiting and positioning for both sides of the bottom of the height adjustment plate 501, thereby further ensuring the stability of the height adjustment plate 501.

[0029] Please see Figure 2In this embodiment, the feed roller 6 is provided with two rollers with a gap between them to facilitate the passage of the blister sheet. The bottom of the feed roller 6 is far away from the antistatic liquid adhesion plate 5. The feed roller 6 is driven by a motor.

[0030] Specifically, the feed roller 6 is used to feed the blister sheet into the conveyor frame 1. The bottom of the feed roller 6 is far away from the antistatic liquid adhesion plate 5, that is, the feed roller 6 does not need to be coated with antistatic liquid, but only serves to guide the feed of the blister sheet.

[0031] Please see Figure 1 In this embodiment, a conveyor roller 7 is provided, and the bottom of the conveyor roller 7 is placed in the antistatic liquid adhesion tray 5. The conveyor roller 7 is driven by a motor.

[0032] Specifically, the conveyor roller 7 is used to convey the thermoformed sheet to the next production stage. When the conveyor roller 7 is conveying, it can achieve the antistatic effect by contacting the antistatic liquid inside the antistatic liquid adhesion tray 5.

[0033] Working principle: The blister sheet is conveyed to the conveyor frame 1 through the feed roller 6, and after passing the top of the conveyor roller 7, it is conveyed to the next production stage. The suction pump 11 conveys the antistatic liquid stored in the antistatic liquid storage tank 3 through the guide pipe 4 to the antistatic liquid adhesion tray 5. Since the bottom of the conveyor roller 7 is placed in the antistatic liquid adhesion tray 5, the bottom of the conveyor roller 7 can adhere to the antistatic liquid in the antistatic liquid adhesion tray 5. When the conveyor roller 7 rotates, it can adhere to the antistatic liquid and come into contact with the blister sheet (that is, the contact surface between the blister sheet and the conveyor roller 7 has antistatic liquid), so that the conveyor roller of the blister sheet can achieve the antistatic effect.

[0034] When the conveying speed of the blister sheet through the conveyor roller 7 increases or decreases, the cylinder 9 can be activated. The power output shaft of the cylinder 9 drives the height adjustment plate 501 to rise or fall in the height adjustment port 8, which in turn drives the antistatic liquid adhesion tray 5 to rise or fall. When the conveyor roller 7 conveys the blister sheet at a faster speed, it means that a larger amount of antistatic liquid is consumed, which allows the antistatic liquid adhesion tray 5 to rise closer to the conveyor roller 7, that is, the contact area between the conveyor roller 7 and the antistatic liquid is larger, and more liquid is adhered. Conversely, when the conveyor roller 7 conveys the blister sheet at a slower speed, it means that a smaller amount of antistatic liquid is consumed, which allows the antistatic liquid adhesion tray 5 to fall away from the conveyor roller 7, that is, the contact area between the conveyor roller 7 and the antistatic liquid is smaller, and less liquid is adhered.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
