TECHNICAL FIELD

[0001] The present application relates to the extrusion conveying technology field of a film blowing machine, in particular to an extrusion conveying device of a film blowing machine. BACKGROUND

[0002] The film blowing machine is used for the production of thin film plastic products. During production and use, the maintenance and care of the film blowing machine becomes an important issue. The film blowing machine usually has an extrusion device that heats and extrudes the granular raw material into a molten state, a conveying device that conveys the molten material to a blowing device, and the blowing device that fills the molten material with air to form a thin film, which is then folded and flattened for rolling to complete the production process. The connecting pipe between the extruder and the blowing device is long, and when the machine stops, the molten material will block the space. Therefore, how to improve the maintenance convenience and cleaning efficiency of the film blowing machine has become a problem to be solved.

[0003] In the existing design of the film blowing machine, in order to achieve efficient conveying of the material, an integrated extrusion conveying device is usually used. The molten plastic is pushed out by the pressure of the molten material extruded by the extruder. Since some plastic materials are hard, it is difficult to push out the solidified material. After pushing out the solidified material, it is reconnected to the blowing device, which is time-consuming and laborious and very inconvenient to clean.

[0004] The deficiencies of the existing film blowing machine extrusion conveying device in terms of disassembly and cleaning mainly include the following aspects: first, the traditional connection method makes the disassembly process complex, which requires a lot of time and labor; second, due to the strong fixation of the connecting parts, it is difficult to completely remove the residues during cleaning, which affects the quality of the next production; finally, frequent disassembly and assembly operations can cause wear and tear at the connection site, affecting the sealing and reducing the service life of the equipment. These problems not only increase the maintenance cost of the equipment, but also affect the production efficiency and the quality stability of the product. CONTENT OF THE INVENTION

At the same time, this design makes the operation more convenient, improves the use convenience and maintenance efficiency of the equipment.

[0012] Preferably, the pressing block and the adjusting frame are detachably connected.

This not only improves the maintainability of the equipment, but also reduces the risk of damage caused by improper disassembly, further improving the reliability and service life of the equipment.

[0014] Preferably, one end of the adjusting rod is further fixedly connected with a rotating wheel.

This design not only improves the convenience of operation, but also reduces the effort required for manual adjustment, improving the work efficiency.

[0016] Preferably, the extrusion conveying device conveying pipe is of a split structure and is fixed by bolts after splicing.

[0017] By adopting the above technical scheme, the split structure of the conveying pipe makes the disassembly of the conveying pipe more convenient, facilitating cleaning and maintenance. It is beneficial to directly take out the condensed material in the pipe, reducing maintenance cost and time.

[0018] Preferably, a groove is formed on the fitting surface of the split structure.

[0019] By adopting the above technical solution, the groove formed on the fitting surface of the split structure can reduce the sealing area, improve the sealing performance, reduce material leakage, and facilitate disassembly and cleaning.

[0020] Preferably, a detachable heat preservation shell is installed outside the conveying pipe of the extrusion conveying device.

[0021] By adopting the above technical solution, the thermal stability of the extrusion conveying device of the film blowing machine can be effectively improved, heat loss can be reduced, and the temperature uniformity of the material during the conveying process can be ensured. Specifically, the setting of the heat preservation shell can prevent the influence of the external environment on the temperature of the material in the conveying pipe, thereby ensuring the quality and processing efficiency of the material.

Therefore, the present application mainly adopts the following one kind of extrusion conveying device of the film blowing machine to achieve the effects of simplifying the maintenance and cleaning process, improving the maintenance convenience and cleaning efficiency of the equipment. The present application will be described in further detail below.

[0033] Embodiment 1

The connection between the extrusion conveying device 2 and the film blowing machine 1 is provided with a locking device 4. The locking device comprises a mounting seat 41, a briquetting 42 and an adjusting frame 43 connected with the briquetting 42. The briquetting 42 is driven by the adjusting frame 43 to lock the extrusion conveying device 2 and the blowing device 1, thereby solving the problems of inconvenient disassembly and difficult cleaning caused by the conventional connection mode, and improving the maintenance convenience and cleaning efficiency of the equipment.

[0035] Specifically, as shown in Figure 4 , Figure 5As shown, the mounting base 41 is provided with an adjusting frame 43, the mounting base 41 is provided with a sliding groove 411, the adjusting frame 43 is installed in the sliding groove 411 and slides along the sliding groove; one end of the adjusting frame 43 is provided with a pressing block 43, and the adjusting frame 43 and the pressing block 42 can be connected by a pin or a bolt, which is convenient for disassembly and replacement. The connecting hole of the pressing block 42 is larger than the diameter of the connecting piece, or is a strip-shaped hole, so that the pressing block 42 and the adjusting frame 43 can still slide relative to each other after the adjusting frame 43 is connected with the pressing block 42. Threaded holes are opened on the adjusting frame 43, and a threaded rod 44 is connected through the threaded holes. One end of the threaded rod 44 is provided with a rotating wheel 441, which is convenient for manual rotation, and the other end is connected to the mounting base 41. When the threaded rod is rotated, the adjusting frame 43 moves up and down along the threaded rod 44, thereby driving the pressing block 42 to approach or move away from the mounting base 41. The abutting surface of the pressing block 42 and the mounting base 41 is provided with an inclined surface, and the inside of the mounting base 41 is also provided with an inclined surface matched with the inclined surface of the pressing block. Through the abutting of the inclined surfaces, the pressing block 42 moves in the direction of the threaded rod 44 and moves in the vertical direction of the moving direction under the action of the inclined surface, realizing the functions of locking and releasing. This design makes the operation simple and fast, and the disassembly and installation can be completed without additional tools.

[0036] In addition, as shown in the drawings, Figure 3 The conveying pipe 21 of the extrusion conveying device 2 adopts a split structure, which is fixed by bolts after splicing. The split structure design makes each part of the conveying pipe can be disassembled and cleaned separately, greatly reducing the disassembly time and workload. A bevel 211 with a certain inclination angle is opened on the abutting surface of the split structure, which can reduce the sealing area and improve the locking force, improve the sealing performance, and prevent material leakage. A detachable heat preservation shell is installed outside the conveying pipe, which can be made of heat insulation materials such as polyurethane foam or glass fiber, effectively reducing heat loss, maintaining stable material temperature, and improving production efficiency.

After the threaded column passes through the hole, it is fixed by a nut. The extruder connecting end of the extrusion conveying device 2 is provided with an interface sleeve, which abuts with the discharge port of the extruder to receive materials. After abutting, a locking nut is used for fixation.

[0038] The implementation principle of the embodiment is that through the design of the locking device, the extrusion conveying device 2 and the blow molding device 1 are quickly disassembled and installed, and the maintenance and cleaning process is simplified. The design of the split structure of the conveying pipe further improves the cleaning efficiency and reduces the downtime. The use of the heat preservation shell ensures the temperature stability of the material during the conveying process, improves the production quality and efficiency. The overall design not only improves the maintenance convenience and cleaning efficiency of the equipment, but also prolongs the service life of the equipment and reduces the maintenance cost. Through the design of the double-layer structure, the high-temperature resistance and heat preservation effect of the conveying pipe are realized, and the conveying efficiency and energy-saving effect are improved. The design of the smooth treatment and the sealing ring further improves the reliability and stability of the conveying process, and ensures the production quality. The overall design not only improves the maintenance convenience and cleaning efficiency of the equipment, but also improves the conveying effect and energy-saving effect, reduces the energy consumption and production cost.
