Description

Technical Field

[0001] This utility model relates to the field of plastic film technology, and in particular to a plastic film extruder for PE film. Background Technology

[0002] In the field of PE film production, plastic film extruders are key equipment for forming films from molten plastic raw materials through extrusion molding processes. With the increasingly diversified demands for PE films from packaging, agriculture, and industry, the width requirements for PE films vary significantly across different scenarios. For example, food packaging may require narrower PE films, while industrial coverings may require wider PE films. Existing plastic film extruders for PE films often produce plastic films of a fixed width, making it difficult to flexibly adjust according to actual production needs. To produce PE films of different widths, different specifications of extrusion dies are usually required. This not only consumes a significant amount of time in die replacement and equipment debugging, reducing production efficiency, but also requires the storage of dies of various specifications, increasing production costs. Therefore, this utility model proposes a plastic film extruder for PE films. Utility Model Content

[0026] Example

[0027] like Figures 1 to 3 As shown, the present invention proposes a plastic film extruder for PE film, comprising: a base 1, a plurality of support frames 2 fixedly arranged on the upper surface of the base 1, the plurality of support frames 2 being equidistantly arranged, a fixed cylinder 3 fixedly snapped onto the support frame 2, which can provide stable support for the fixed cylinder 3, and a hopper 4 fixedly and through the outer wall of the fixed cylinder 3, which facilitates the addition of plasticized plastic into the fixed cylinder 3 for extrusion and conveying.

[0028] Furthermore, a fixing block 5 is fixedly installed on the upper surface of the base 1. A motor 6 and a reducer 7 are fixedly installed on the upper surface of the fixing block 5. The output end of the motor 6 is connected to the reducer 7, and the speed of the output end of the motor 6 can be controlled by the reducer 7.

[0029] Secondly, a spiral conveying rod 8 is rotatably mounted inside the fixed cylinder 3 via bearings, which can convey the plastic inside the fixed cylinder 3. One end of the spiral conveying rod 8 is fixedly connected to a screw head 10, which can reduce the resistance to the flow of plastic. One end of the spiral conveying rod 8 passes through the fixed cylinder 3 and is connected to the reducer 7, which can drive the motor 6 to rotate the spiral conveying rod 8 stably through the reducer 7.

[0030] like Figure 2 and Figure 3As shown in the figure, a control component 9 for adjusting the width of the extruded plastic film is connected to the outlet end of the fixed cylinder 3. The control component 9 includes a connecting pipe 90 connected to the outlet end of the fixed cylinder 3. One end of the connecting pipe 90 is connected to a discharge head 91. Guide grooves 92 are formed on both sides of the discharge head 91, and the guide grooves 92 are connected to the discharge openings on the discharge head 91. A group of sealing guide strips 93 are slidably arranged inside the guide grooves 92, so that the size of the discharge openings on the discharge head 91 can be blocked by the sealing guide strips 93, thereby controlling the extrusion width of the plastic film. The guide grooves 92 and the sealing guide strips 93 are arranged in an "H" shape, which increases their connection structure and can seal and block the guide grooves 92 at the same time. Opposite ends of the sealing guide strips 93 are fixedly provided with connecting blocks 94. One end of the connecting block 94 is rotatably connected to a linkage rod 95 through a shaft rod. A fixed frame 96 is fixedly arranged on the connecting pipe 90, and the fixed frame 96 is arranged in a "冂" shape, which can provide stable support. Limit grooves 97 are respectively formed on both sides of the fixed frame 96, and the limit grooves 97 are slidably connected to the linkage rod 95, which can guide the linkage rod 95 and make it move stably. An adjusting screw rod 98 is threadedly penetrated through the fixed frame 96. The lower end of the adjusting screw rod 98 is rotatably connected to a connecting seat 99 through a bearing, which can drive the connecting seat 99 to move vertically up and down stably. The connecting seat 99 is rotatably connected to the linkage rod 95 through a shaft rod, thereby driving the sealing guide strip 93 to slide stably in the guide groove 92.

[0031] Furthermore, a connecting plate 11 is arranged between the fixed cylinder 3 and the connecting pipe 90. A slot 12 is formed on the upper surface of the connecting plate 11. The slot 12 is connected to the fixed cylinder 3 and the connecting pipe 90, which is convenient for extruding plastic. A filter plate 13 is slidably arranged inside the slot 12. The filter plate 13 can filter impurities in the plastic, thereby improving the quality of the extruded plastic film. A clamping groove 14 is formed on the upper surface of the connecting plate 11. A clamping plate 15 is fixedly arranged on the upper side of the filter plate 13, and the clamping plate 15 can be hermetically clamped with the clamping groove 14, thereby preventing the extruded plastic from leaking. A handle 16 is fixedly arranged on the upper surface of the clamping plate 15, which is convenient for pulling out the filter plate 13 from the slot 12 for cleaning.

[0032] The working principle of this embodiment is as follows: Manually rotate the adjusting screw rod 98 on the fixed frame 96 according to the required width of the extruded plastic film. Since the adjusting screw rod 98 is threadedly connected to the fixed frame 96, its rotation will drive the connecting seat 99 at the lower end to move up and down. The movement of the connecting seat 99 will pull the connecting block 94 through the linkage rod 95, and then make the sealing guide strip 93 slide in the guide groove 92 of the discharge head 91. Because the guide grooves 92 and the sealing guide strips 93 are in an "H" shape, the stability and sealing performance of the sliding process can be ensured. By adjusting the distance between the two sealing guide strips 93, the width of the outlet of the discharge head 91 can be flexibly changed, thereby determining the width of the extruded PE film, and there is no need to replace different specifications of discharge molds, which greatly saves the preparation time.

[0033] After adjusting the width, the plasticized plastic is fed from the hopper 4 into the fixed cylinder 3. The motor 6 is started, and its power is transmitted to the screw conveyor 8 after being reduced in speed by the reducer 7, causing the screw conveyor 8 to rotate within the fixed cylinder 3. During rotation, the screw conveyor 8 transports the raw material forward while simultaneously compressing it. Upon reaching the outlet of the fixed cylinder 3, the raw material enters the connecting pipe 90 through the connecting plate 11. At this point, the filter plate 13 in the slot 12 on the connecting plate 11 filters the raw material, effectively removing impurities and ensuring the quality of the subsequently extruded PE film. If the filter plate 13 needs cleaning or replacement, simply hold the handle 16 to pull the filter plate 13 out of the slot 12, clean or replace it, and then reinsert it. The filter plate 13 is then secured by the cooperation of the retaining plate 15 and the retaining groove 14. The operation is very convenient.

[0034] The filtered raw material continues to enter the discharge head 91 through the connecting pipe 90, and is finally extruded from the discharge port with the adjusted width to form a PE film of the required width. During the extrusion process, the screw head 10 at one end of the screw conveyor 8 ensures that the raw material enters the connecting pipe 90 smoothly. The whole process is stable and efficient, which not only ensures the quality of the PE film, but also improves production efficiency and reduces production costs.

[0035] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
