Description

Technical Field

[0001] This utility model relates to the field of plastic processing machinery technology, specifically a PE plastic film extruder. Background Technology

[0002] Polyethylene plastic film is widely used in food packaging, agricultural covering, and industrial stretch film due to its excellent chemical stability, mechanical properties and cost-effectiveness. As the market demands for film quality and production efficiency continue to increase, the technological upgrading of PE plastic film extruders has become the key to the industry's development. Therefore, it is particularly important to develop a new type of PE plastic film extruder.

[0003] A PE plastic film extruder, as described in reference announcement number CN218701107U, includes an extruder body comprising a frame, a drive assembly, a feeding assembly, and a heating and conveying assembly. The feeding assembly includes a feeding hopper, within which a first filter section is rotatably disposed, and a second filter section is fixedly disposed. This invention achieves a relatively sealed feeding effect within the chamber by using a feeding hopper and a sealing cover, preventing dust generation during powder feeding and effectively solving the problem of pollution of the working environment during powder feeding. Furthermore, it incorporates a stirring mechanism... The mixing blades, the first filter section, and the second filter section achieve dual filtration while dispersing the material, avoiding the problem of slow material discharge caused by material accumulation. By setting a fixed filter cover and a movable filter cover, the material is crushed by the squeezing of the bottom surface of the movable filter cover and the fixed filter cover, which effectively solves the problem of larger particles accumulating in the feed hopper after screening. As can be seen from the above, although this extruder can be used well, it is usually not convenient to easily control the rotation speed of the screw roller, which still has some inconvenience in the use of the extruder and needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a PE plastic film extruder to solve the problem mentioned in the background art that although extruders can be used well, it is usually not convenient to control the rotation speed of the spiral rollers, which makes the extruder still inconvenient to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PE plastic film extruder, comprising a base, a cabinet fixed to the top of the base, a machine platform fixed to the top of the cabinet, an extrusion box on one side of the machine platform, an extruder body at the upper end of the extrusion box, one end of the extruder body extending to the outside of the extrusion box, the other end of the extruder body extending to the outside of the extrusion box and having an extrusion head installed thereon, a gearbox fixed to the top of the machine platform, a power box on the top of the machine platform on the side of the gearbox away from the extrusion box, a motor installed inside the power box, one end of the motor extending to the inside of the gearbox and having a first gear installed thereon, a second gear rotatably mounted on the inner wall of the gearbox above the first gear, the second gear meshing with the first gear, a third gear mounted on one end of the second gear via a rotating shaft, a fourth gear rotatably mounted on the inner wall of the gearbox above the third gear, the fourth gear meshing with the third gear, and one end of the fourth gear extending to the inside of the extruder body via a rotating shaft and having a spiral roller installed thereon.

[0006] Preferably, a discharge port is installed at the top of the extruder body between the gearbox and the extrusion box, and a storage tank is fixedly installed at the top of the discharge port to store and process PE plastic film raw materials.

[0007] Preferably, the top of the storage tank is equipped with a tank cover, and the inside of the storage tank is equipped with an arc-shaped screen. The arc-shaped screen is designed to filter out large particles in the PE plastic film raw material.

[0008] Preferably, the outer surfaces of both sides of the lower end of the extrusion box are provided with a number of heat dissipation holes, and rollers are installed at the corners of the bottom end of the base. The rollers are used to transport and transfer the extruder.

[0009] Preferably, a nut seat is provided on the outer wall of the base on one side of the roller, and a screw is installed in the internal thread of the nut seat. Both ends of the screw extend to the outside of the nut seat. The nut seat is provided to accommodate the screw.

[0010] Preferably, a handle is installed at the top of the screw, and an anti-slip foot is installed at the bottom of the screw, so as to stabilize the extruder.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the PE plastic film extruder not only improves the convenience of using the extruder, but also achieves the purpose of easily extruding PE plastic film raw materials, and also achieves the purpose of easily transporting and stably placing the extruder.

[0012] (1) The first gear is driven by the motor to rotate. Since the first gear and the second gear mesh with each other and the diameter of the first gear is smaller than that of the second gear, the motor drives the second gear to rotate slowly through the first gear. Since the third gear and the fourth gear mesh with each other and the diameter of the third gear is smaller than that of the fourth gear, the second gear drives the fourth gear to rotate slowly through the third gear. The fourth gear drives the spiral roller to rotate slowly synchronously. This allows for multi-stage deceleration of the spiral roller, making it easier to adjust the rotation speed of the spiral roller and thus improving the convenience of using the extruder.

[0013] (2) By injecting PE plastic film raw material into the storage tank, the arc screen is set to filter the PE plastic film raw material to remove large particles in the PE plastic film raw material. Then, due to gravity, the PE plastic film raw material falls into the extruder body through the discharge port. The rotating spiral roller conveys the PE plastic film raw material to the right in a spiral direction so that the PE plastic film raw material is extruded through the extrusion head, thereby achieving the purpose of conveniently extruding the PE plastic film raw material.

[0014] (3) By rotating the handle, the drive screw is rotated inside the nut seat and slides up and down, so that the screw drives the anti-slip foot seat to move up and down. When the anti-slip foot seat replaces the roller and contacts the ground, the extruder can be stably placed. When the roller replaces the anti-slip foot seat and contacts the ground, the extruder can be pushed to slide and move, thus achieving the purpose of easy and convenient transportation and stable placement of the extruder.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-4 An embodiment of this utility model is provided: a PE plastic film extrusion machine, including a base 1, a cabinet 4 fixed at the top of the base 1, a machine platform 5 fixedly installed at the top of the cabinet 4, an extrusion box 10 provided on the outer wall of one side of the machine platform 5, and several heat dissipation holes 3 provided on the outer surfaces of both sides of the lower end of the extrusion box 10, and rollers 2 installed at the corners of the bottom end of the base 1.

[0022] In use, the rollers 2 are used to transport and transfer materials from the extruder.

[0023] A nut seat 12 is provided on the outer wall of the base 1 on one side of the roller 2. A screw 13 is installed in the internal thread of the nut seat 12, and both ends of the screw 13 extend to the outside of the nut seat 12.

[0024] In use, the nut seat 12 is provided to accommodate the screw 13.

[0025] A handle 14 is installed at the top of the screw 13, and an anti-slip foot 15 is installed at the bottom of the screw 13.

[0026] When in use, the anti-slip feet 15 are provided to ensure the extruder is securely placed.

[0027] An extruder body 16 is provided at the upper end of the extrusion box 10. One end of the extruder body 16 extends to the outside of the extrusion box 10, and the other end of the extruder body 16 extends to the outside of the extrusion box 10 and is equipped with an extrusion head 11. A gearbox 6 is fixedly installed at the top of the machine base 5. A discharge port 23 is installed at the top of the extruder body 16 between the gearbox 6 and the extrusion box 10. A storage tank 8 is fixedly installed at the top of the discharge port 23.

[0028] When in use, the storage tank 8 is used to store and process PE plastic film raw materials;

[0029] The top of the storage tank 8 is fitted with a tank cover 9, and the inside of the storage tank 8 is fitted with an arc-shaped screen 24;

[0030] When in use, the arc-shaped screen 24 is set to filter out large particles in the PE plastic film raw material.

[0031] A power box 7 is located at the top of the machine base 5 on the side of the gearbox 6 away from the extrusion box 10. A motor 18 is installed inside the power box 7. One end of the motor 18 extends into the interior of the gearbox 6 and is fitted with a first gear 19. A second gear 20 is rotatably mounted on the inner wall of the gearbox 6 above the first gear 19. The second gear 20 meshes with the first gear 19. A third gear 21 is mounted on one end of the second gear 20 via a rotating shaft. A fourth gear 22 is rotatably mounted on the inner wall of the gearbox 6 above the third gear 21. The fourth gear 22 meshes with the third gear 21. One end of the fourth gear 22 extends into the interior of the extruder body 16 via a rotating shaft and is fitted with a spiral roller 17.

[0032] In this embodiment, the screw 13 is driven to rotate and slide up and down inside the nut seat 12 by rotating the handle 14. This causes the screw 13 to move the anti-slip foot 15 up and down. When the anti-slip foot 15 replaces the roller 2 and contacts the ground, the extruder is securely positioned. When the roller 2 replaces the anti-slip foot 15 and contacts the ground, the extruder is moved and transported. Then, the first gear 19 is driven to rotate by the motor 18. Because the first gear 19 meshes with the second gear 20, and the diameter of the first gear 19 is smaller than the diameter of the second gear 20, the motor 18 drives the second gear 20 to rotate slowly via the first gear 19. Furthermore, because the third gear 21 meshes with the fourth gear 22, and the diameter of the third gear 21 is smaller than the fourth gear 22, the extruder is moved up and down by the motor 18 via the first gear 19. The diameter of the second gear 20 is smaller than that of the fourth gear 22, so that the third gear 21 further drives the fourth gear 22 to rotate slowly. The fourth gear 22 then drives the spiral roller 17 to rotate slowly and synchronously, allowing for multi-stage speed reduction control of the spiral roller 17. Finally, the PE plastic film raw material is injected into the storage tank 8. Due to the setting of the arc screen 24, the PE plastic film raw material is filtered to remove large particles. Subsequently, the PE plastic film raw material falls into the extruder body 16 through the discharge port 23 due to gravity. The rotating spiral roller 17 conveys the PE plastic film raw material spirally to the right, so that the PE plastic film raw material is extruded through the extrusion head 11, thus completing the use of the extruder.
