Description

Technical Field

[0001] This utility model relates to the field of blown film extrusion technology, specifically a PE film extrusion blown film extrusion machine with stable feeding. Background Technology

[0002] Aluminum-plastic composite packaging material is a common packaging material widely used in packaging milk and soft drinks. In the processing and production of aluminum-plastic composite packaging materials, the production of PE film is a major step. PE film production is completed using an extrusion blown film machine. The traditional extrusion blown film structure of PE film is complex. Due to different tilting angles, the amount of thermoplastic raw material entering varies. When too much or too little raw material enters, the load on the internal motor increases or decreases, leading to an unstable operating environment and affecting raw material conveying, thus impacting the quality of the blown film product.

[0003] An existing patent (publication number: CN221913247U) discloses a PE film extrusion blown film machine with stable feeding. Through the interaction of structures such as the feeding box, cross frame, distribution plate, transmission gear and drive gear, the amount of material fed into the main body of the equipment can be controlled by controlling the spacing between multiple distribution plates. Each pair of distribution plates forms a group, and the drive gears of each group face opposite directions, which can control the synchronous and opposite rotation of the two distribution plates. The feeding amount can be quickly adjusted according to the extrusion speed, effectively reducing the burden on the main body of the equipment.

[0004] While the aforementioned patent allows for control of the feed rate by changing the angle between the two dividing plates, it still has certain drawbacks. The feed box and the main body of the equipment are directly connected in the vertical direction. Although the feed inlet size can be adjusted by changing the angle of the dividing plates, the pressure exerted by the material above on the material below changes when the total volume of material inside the feed box changes. Different downward pressures during the feeding process result in variations in the total amount of material passing through per unit time, which can lead to increased or decreased load on the internal motor, causing instability in the operating environment. Furthermore, the patent uses a fastening nut to fix the blown film head, making disassembly and replacement of the blown film head inconvenient during use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a PE film extrusion blown film machine with stable feeding, which has the advantages of stable feeding and is unaffected by the environment, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PE film extrusion blown film machine with stable feeding, comprising a base and a main body of the equipment mounted on the upper surface of the base. The main body of the equipment includes a shell, and a feeding assembly is provided at the left end of the shell. The feeding assembly includes a transverse guide tube, the bottom left side of which is connected to the shell. A feeding cylinder is fixedly connected to and communicates with the outer surface of the transverse guide tube. A first auger is rotatably connected to the inner wall of the transverse guide tube, and a second auger is rotatably connected to the inner wall of the shell.

[0007] Furthermore, a feeding motor is installed at the end of the transverse guide tube, and the output end of the feeding motor is connected to the first auger.

[0008] With the above scheme, the feeding motor can drive the first auger to rotate, and the rotation of the first auger pushes the material inside the transverse guide tube into the outer shell.

[0009] Furthermore, a drive motor is installed at the left end of the housing, and the output end of the drive motor is connected to the second auger.

[0010] The above scheme enables the drive motor to rotate the second auger, thereby moving the material inside the casing.

[0011] Furthermore, the feeding assembly also includes a fixing plate fixed to the top of the feeding cylinder, an auxiliary motor is mounted on the upper surface of the fixing plate, and a third auger is mounted on the output end of the auxiliary motor.

[0012] The above solution avoids blockage at the connection point between the feed cylinder and the transverse guide tube by rotating the third auger.

[0013] Furthermore, a discharge pipe is fixedly connected to the bottom right side of the outer shell, and a blown film head is provided on the right side of the discharge pipe. A snap-fit ​​assembly is provided between the discharge pipe and the blown film head. The snap-fit ​​assembly includes a bearing ring fixed to the discharge pipe, and a snap-fit ​​ring corresponding to the bearing ring is fixed to the end of the blown film head. Multiple limiting grooves are opened on the side of the bearing ring, and a moving block is slidably connected to the inner wall of the limiting groove. The end of the moving block is made with an arc cut. An L-shaped groove block corresponding to the limiting groove is fixed to the side of the snap-fit ​​ring, and the L-shaped groove block is snapped into the limiting groove.

[0014] The above scheme maintains a stable connection between the bearing ring and the locking ring by interlocking the L-shaped groove block and the limiting groove.

[0015] Furthermore, a reset spring and a reset telescopic rod are fixed to the side of the movable block, and the other end of the reset spring and the reset telescopic rod are fixed to the bearing ring.

[0016] The above solution maintains the stability of the moving block through the return spring and the return telescopic rod. Under the elastic force of the return spring, the moving block can squeeze the L-shaped groove block, thereby maintaining the stable engagement between the L-shaped groove block and the limiting groove.

[0017] Furthermore, a heating assembly is provided on the outer side of the outer shell. The heating assembly includes a protective shell, which is fixed to the outer shell. A heating tube is provided inside the protective shell and is wound around the outer surface of the outer shell. The heating tube is connected to the output end of an external heating device.

[0018] The above method uses an external heating device to heat the heating element, which in turn heats the outer casing.

[0019] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0020] This stable feeding PE film extrusion blown film machine, by setting a transverse guide, prevents the feed cylinder from being directly connected to the outer shell. After leaving the feed cylinder, the material enters the transverse guide and is pushed into the inner shell by the first auger. This ensures that no matter how much material is in the feed cylinder, it will not affect the feed rate per unit time from the transverse guide to the inner shell. By setting a third auger to prevent the feed cylinder from getting blocked, the material inside the transverse guide is always full even if there is material in the feed cylinder, thus achieving uniform and stable feeding.

[0039] It should be noted that during use, the speed of the feed motor 304 is adjusted according to the blowing situation of the blown film head 4, thereby adjusting the feed rate per unit time.

[0040] The working principle of the above embodiment is as follows: the raw material is added into the feed cylinder 302 and enters the transverse guide tube 301 through the feed cylinder 302. The feed motor 304 and the auxiliary motor 306 are started. The feed motor 304 drives the first auger 303 to rotate. The rotation of the first auger 303 pushes the raw material inside the transverse guide tube 301 into the interior of the outer shell 201. The auxiliary motor 306 drives the third auger 307 to rotate. The rotation of the third auger 307 prevents the connection between the feed cylinder 302 and the transverse guide tube 301 from being blocked.

[0041] Simultaneously, the drive motor 203 is started. After the raw material enters the interior of the outer shell 201, it is melted by the heating component 6. The drive motor 203 drives the second auger 202 to rotate. The rotation of the second auger 202 drives the melted raw material into the blown film head 4 for blowing. When the blown film head 4 needs to be replaced, the blown film head 4 is rotated. The blown film head 4 drives the locking ring 502 to rotate. The L-shaped groove block 504 disengages from the limiting groove of the bearing ring 501. The locking ring 502 disengages from the bearing ring 501. A new blown film head 4 is installed. The L-shaped groove block 504 fixed on the back of the locking ring 502 of the new blown film head 4 pushes open the moving block 503. The L-shaped groove block 504 engages with the groove of the bearing ring 501. The moving block 503 is reset under the elastic force of the return spring 505 and squeezes the L-shaped groove block 504, thereby maintaining the stable engagement between the L-shaped groove block 504 and the limiting groove.
