Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3As shown, this utility model provides a suction mechanism for a vacuum forming machine, including a base frame 1. A vacuum forming mechanism 3 is fixedly mounted on the upper surface of the base frame 1. Feeding mechanisms 2 are fixedly mounted on both sides of the vacuum forming mechanism 3. The feeding mechanism 2 includes a feeding rack 20. One side of the feeding rack 20 is fixedly connected to the vacuum forming mechanism 3. A motor 22 is mounted on one side of the feeding rack 20. A drive sprocket 21 is fixedly mounted on the output end of the motor 22. A drive feeding roller 29 is fixedly mounted on one side of the drive sprocket 21. A chain 25 is meshed with the outer side of the drive sprocket 21. A driven sprocket 26 is meshed with the inner side of the chain 25. A driven feeding roller 27 is fixedly mounted on one side of the driven sprocket 26. During the operation of the vacuum forming machine, the suction mechanism 2 first... When machine 22 starts, its output end drives drive sprocket 21 to start rotating. Drive sprocket 21 is connected to chain 25 and drives driven sprocket 26 to rotate synchronously. At this time, drive feeding roller 29 and driven feeding roller 27, which are fixedly connected to drive sprocket 21 and driven sprocket 26 respectively, also start to rotate. Since the outer side of the feeding roller is coated with anti-slip coating, it can drive the plastic sheet to move and prevent it from slipping during feeding. Under the clamping of drive feeding roller 29 and driven feeding roller 27, the plastic sheet is stably conveyed to the top of the vacuum forming mold 33 of vacuum forming mechanism 3, preparing for subsequent vacuum forming operations. The entire feeding process is stable and efficient, ensuring the continuity and accuracy of vacuum forming machine operation.

[0018] A mounting bracket 23 is fixedly provided on one side of the feeding rack 20. The inner wall of one side of the mounting bracket 23 is fixedly connected to the motor 22. Two symmetrically distributed support brackets 24 are fixedly provided on the lower surface of the feeding rack 20. Two positioning grooves 28 are opened on the side of the feeding rack 20 away from the motor 22. The positioning grooves 28 are rotatably connected to the drive feeding roller 29 and the driven feeding roller 27. The outer sides of the drive feeding roller 29 and the driven feeding roller 27 are coated with an anti-slip coating. The anti-slip coating on the outer side of the feeding roller can firmly drive the plastic sheet to move. The motor 22 can be fixed on one side of the feeding rack 20 through the mounting bracket 23. The feeding rack 20 can be supported by the support brackets 24. The positioning grooves 28 can limit the rotation of the drive feeding roller 29 and the driven feeding roller 27.

[0019] The vacuum forming mechanism 3 includes a suction platform 30. The lower surface of the suction platform 30 is fixedly connected to the base frame 1, and one side of the suction platform 30 is fixedly connected to the feeding rack 20. A suction connection port 38 is fixedly provided on the lower surface of the suction platform 30. A vacuum forming mold 33 is provided on the upper surface of the suction platform 30. A vacuum forming groove 35 is opened on the upper surface of the vacuum forming mold 33. A suction hole 36 is opened on the lower inner wall of the vacuum forming groove 35. Two fixing plates 34 are fixedly provided on both sides of the vacuum forming mold 33, and two fixing blocks 31 are fixedly provided on both sides of the suction platform 30. When the feeding mechanism 2 conveys the plastic sheet to the top of the vacuum forming mold 33, the vacuum forming mechanism 3 starts to work. First, it is connected to a negative pressure source through the suction connection port 38, and the suction inside the suction platform 30... Negative pressure is generated in cavity 37. Since the upper surface of the vacuum forming mold 33 has a vacuum forming groove 35 and the lower inner wall of the vacuum forming groove 35 has a suction hole 36 that communicates with the suction cavity 37, the plastic sheet is tightly adsorbed in the vacuum forming groove 35 of the vacuum forming mold 33 under the action of negative pressure. Next, the plastic sheet is deformed under the shape constraint of the vacuum forming mold 33 and finally shaped into a vacuum forming product that is consistent with the shape of the vacuum forming mold 33. After the forming is completed, the vacuum forming product can be removed from the vacuum forming mold 33 by disconnecting the negative pressure source or using other demolding methods, thus completing the entire vacuum forming process. The vacuum forming mechanism 3 makes the vacuum forming process precise and efficient, and can produce vacuum forming products with complex shapes and accurate dimensions.

[0020] The upper surface of the suction platform 30 is provided with a suction chamber 37, which is connected to a suction hole 36. The upper surfaces of the fixing plate 34 and the fixing block 31 are both provided with fixing holes 32. Through the suction hole 36 connected to the suction chamber 37, the plastic sheet is tightly adsorbed into the vacuum forming groove 35 of the vacuum forming mold 33 under the action of negative pressure. The vacuum forming mold 33 and the suction platform 30 can be fixed through the fixing holes 32.

[0021] Working principle: During the operation of the vacuum forming machine, the motor 22 starts first through the feeding mechanism 2, and its output end drives the drive sprocket 21 to start rotating. The drive sprocket 21 is connected to the chain 25 and drives the driven sprocket 26 to rotate synchronously. At this time, the drive feeding roller 29 and the driven feeding roller 27, which are fixedly connected to the drive sprocket 21 and the driven sprocket 26 respectively, also start to rotate. Since the outer side of the feeding roller is coated with an anti-slip coating, it can drive the plastic sheet to move and prevent it from slipping during the feeding process. Under the clamping of the drive feeding roller 29 and the driven feeding roller 27, the plastic sheet is stably transported to the vacuum forming mold 33 of the vacuum forming mechanism 3, preparing for the subsequent vacuum forming operation. The entire feeding process is stable and efficient, ensuring the continuity and accuracy of the vacuum forming machine's operation.

[0022] When the feeding mechanism 2 delivers the plastic sheet to the top of the vacuum forming mold 33, the vacuum forming mechanism 3 begins to work. First, it connects to the negative pressure source through the suction port 38, and the suction chamber 37 inside the suction platform 30 begins to generate negative pressure. Since the upper surface of the vacuum forming mold 33 has a vacuum forming groove 35, and the lower inner wall of the vacuum forming groove 35 has a suction hole 36 that communicates with the suction chamber 37, the plastic sheet is tightly adsorbed into the vacuum forming groove 35 of the vacuum forming mold 33 under the action of negative pressure. Next, the plastic sheet is deformed under the shape constraint of the vacuum forming mold 33, and finally shaped into a vacuum forming product that is consistent with the shape of the vacuum forming mold 33. After the forming is completed, the vacuum forming product can be removed from the vacuum forming mold 33 by disconnecting the negative pressure source or using other demolding methods, thus completing the entire vacuum forming process. The vacuum forming mechanism 3 makes the vacuum forming process precise and efficient, and can produce vacuum forming products with complex shapes and accurate dimensions.
