[0001] The utility model belongs to the technical field of blown film machine equipment, and particularly relates to a high-efficiency blown film machine for preparing plastic packaging bags. Background Technique

[0002] Plastic packaging bags are a type of material mainly made of synthetic or natural polymer resins. After adding various additives, they have ductility at a certain temperature and pressure and can fix their shapes after cooling. In the process of preparing plastic packaging bags, a blown film machine is required. The blown film machine melts plastic particles and then blows them into films. The films blown with brand-new particles are new materials, with uniform color, cleanliness, and good stretching properties for the bags.

[0003] However, when the existing blown film machines are in use, since there will be some metal impurities doped in the materials, and the traditional blown film machines cannot collect the metal impurities well, it is often necessary for workers to pre-screen the materials, which not only reduces the working efficiency of the blown film machine but also reduces its practicability. Therefore, a high-efficiency blown film machine for preparing plastic packaging bags is needed to improve the above problems. Summary of the Utility Model

[0004] In order to overcome the above defects, the utility model provides a high-efficiency blown film machine for preparing plastic packaging bags, which solves the problems that since there will be some metal impurities doped in the materials, and the traditional blown film machines cannot collect the metal impurities well, it is often necessary for workers to pre-screen the materials, which not only reduces the working efficiency of the blown film machine but also reduces its practicability.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A high-efficiency blown film machine for preparing plastic packaging bags, including a blown film machine body, a blanking housing is arranged on the blown film machine body, a processing box is arranged on the blanking housing, a connecting rod is rotatably arranged in the processing box, a cam is arranged at one end of the connecting rod, a screening frame is lapped on the side surface of the cam, the front and back surfaces of the screening frame are hinged in the processing box through pin shafts, a magnet is arranged in the screening frame, two springs are arranged under the screening frame, the other ends of the springs are provided with connecting blocks, the connecting blocks are connected with the processing box, a fixing plate is arranged on the side surface of the processing box, a motor is arranged under the fixing plate, the output shaft of the motor is connected with the other end of the connecting rod, a transmission component is arranged on the side surface of the connecting rod, an anti-blocking component is arranged in the blanking housing, and the anti-blocking component is connected with the transmission component.

[0013] 1. The efficient film blowing machine for preparing plastic packaging bags is provided with a motor, a connecting rod, a cam, a screening frame, a magnet, a spring and an anti-blocking rod. With the cooperation of the motor, the connecting rod, the cam, the screening frame, the magnet, the spring and the anti-blocking rod, the traditional film blowing machine is further avoided from being unable to collect metal impurities well and often requiring staff to pre-screen the materials.

By providing the connecting rod 9 and the cam 10, the connecting rod 9 plays a role in supporting and limiting the cam 10, thereby ensuring that the cam 10 does not wobble randomly during rotation; the side surface of the cam 10 abuts against a screening frame 11, the front and back surfaces of the screening frame 11 are respectively hinged in the processing box 3 through pin shafts 12, and a magnet 13 is provided in the screening frame 11. By providing the magnet 13, the magnet 13 can effectively perform preliminary adsorption and screening on the metal impurities doped in the material. Two springs 15 are provided under the screening frame 11, and a connecting block 16 is provided at the other end of the springs 15. By providing the connecting block 16 and the springs 15, the connecting block 16 plays a role in supporting and limiting the springs 15, enabling the springs 15 to work stably. At the same time, the springs 15 provide a resetting effect on the screening frame 11, and the connecting block 16 is connected to the processing box 3;

[0021] On the side of the processing box 3, there is a fixed plate 7. Below the fixed plate 7, there is a motor 6. The output shaft of the motor 6 is connected to the other end of the connecting rod 9. On the side of the connecting rod 9, there is a transmission assembly 5. The transmission assembly 5 includes a second turntable 53. The second turntable 53 is arranged on the side of the connecting rod 9. On the side of the second turntable 53, there is a belt 52. The side of the belt 52 is lapped with a first turntable 51. By setting the first turntable 51, the belt 52 and the second turntable 53, with the mutual cooperation of the first turntable 51, the belt 52 and the second turntable 53, the power of the connecting rod 9 is smoothly transmitted to the movable rod 42. Inside the blanking housing 2, there is an anti-blocking assembly 4. The anti-blocking assembly 4 includes a positioning bearing 41. The positioning bearing 41 is arranged inside the blanking housing 2. Inside the positioning bearing 41, there is a movable rod 42. By setting the positioning bearing 41, the positioning bearing 41 plays a role in supporting and limiting the movable rod 42, enabling the movable rod 42 to rotate smoothly inside the positioning bearing 41. The movable rod 42 is connected to the first turntable 51. On the side of the movable rod 42, there are several anti-blocking rods 43. The anti-blocking assembly 4 is connected to the transmission assembly 5. Below the processing box 3, there is a through hole 18. The through hole 18 is communicated with the blanking housing 2. Inside the processing box 3, there is a guide plate 17. Below the screening frame 11, there is a through hole 14. The guide plate 17 is located directly below the through hole 14. On the processing box 3, there is a feed hopper 8.

[0022] The working principle of the present utility model is as follows:

[0023] During use, first control the motor 6 to work, so that the motor 6 drives the connecting rod 9 to rotate. The connecting rod 9 drives the cam 10 to rotate. At this time, under the mutual cooperation of the pin shaft 12 and the spring 15, the cam 10 drives the screening frame 11 to perform a reciprocating swinging motion. Then pour the material into the processing box 3 through the feed hopper 8, and make the material contact with the screening frame 11. At the same time, the connecting rod 9 drives the second turntable 53 to rotate. The second turntable 53 drives the first turntable 51 to rotate through the belt 52, so that the first turntable 51 drives the movable rod 42 to rotate;

[0024] The movable rod 42 drives the anti-blocking rods 43 to rotate. Since the screening frame 11 is inclined and swings reciprocally with the cam 10, the metal impurities in the material are adsorbed by the magnet 13. The screened material smoothly falls into the blanking housing 2 through the through hole 14, the guide plate 17 and the through hole 18. The anti-blocking rods 43 disperse and rotate the material. Finally, start the operation of the blown film machine body 1, and the material can be conveyed to the heating area through the extrusion screw for blown film processing.
