[0002] The IXPE film web extrusion production line is a complete equipment combination for processing raw materials such as polyethylene (PE) into IXPE (electron radiation cross-linked polyethylene) film webs through extrusion, cross-linking and other processes. The core is to shape the molten raw materials into a sheet through an extruder, and then to give the material excellent cushioning, insulation, temperature resistance and other properties through radiation cross-linking and other treatments. It is the key front-end equipment for IXPE film production. The core composition and function of the production line, the raw material processing system: including a dryer, a mixer and the like, is used to remove moisture from the raw materials and mix additives (such as cross-linking agents and blowing agents) in proportion to ensure the purity and uniformity of the raw materials, providing a stable foundation for subsequent extrusion, the extrusion main machine: the core equipment, through the rotation of the screw to pressurize the molten PE raw materials into the mold to form a continuous sheet (web), the design of the screw and the temperature control directly affect the thickness accuracy and mechanical properties of the web, the shaping and cooling device: the high-temperature sheet extruded from the mold is cooled and shaped by a cooling roller group to ensure the dimensional stability of the web and avoid deformation due to shrinkage, the traction and winding system: the traction machine uniformly pulls the sheet, and the winding machine winds the web into a roll for subsequent radiation cross-linking, foaming and other processing links, auxiliary systems: such as temperature control systems (to maintain stable extrusion temperature at each stage), electrical control systems (to coordinate equipment linkage) and the like, to ensure continuous and efficient operation of the production line.

[0003] After searching, it is found that a IXPE film web extrusion production line is disclosed in Chinese application No. CN202421239168.3. The production line includes an extruder body, the front surface of which is provided with a conveying assembly. The conveying assembly includes symmetrically designed fixed plates, between which a plurality of heat dissipation pipes are arranged. The right side of the heat dissipation pipes is communicated with a cooling pipe, the end of the cooling pipe away from the heat dissipation pipes extends into the inside of a three-way pipe, the right side of the three-way pipe is installed with a water tank, and the right side of the three-way pipe extending into the inside of the water tank is provided with a water supply pipe. The production line has the advantages that the web can be cooled when passing through the auxiliary roller, will not stick to the auxiliary roller, and can be well cooled and shaped, avoiding the need for subsequent workers to split the web, and reducing the labor intensity of the workers.

An electric telescopic rod 23 is connected, and a first connecting plate 24 is fixedly connected to the upper end of the electric telescopic rod 23. A second connecting plate 25 is fixedly connected to the inner side of the opposite end of the first connecting plate 24, and a guide roller 26 is rotatably connected to the opposite side of the second connecting plate 25. When extruding the film sheet, the extruded film sheet is first passed through multiple sets of guide cylinders 21 and guide rollers 26 in sequence, and then pulled by an external traction winding device. Subsequently, multiple sets of electric telescopic rods 23 are started. After the electric telescopic rods 23 are started, the output shaft drives the first connecting plate 24 and the second connecting plate 25 to move down, so that the second connecting plate 25 drives the guide roller 26 to move down to press down and restrict the film sheet, so that the film sheet can fit more tightly with the guide cylinder 21.

[0030] Reference Figure 1- Figure 4 The diversion assembly 3 includes a diverter 31 fixedly connected to the outer side of one end of the transmitter 22, and a first water pipe 32 fixedly connected to the end of the diverter 31 away from the transmitter 22 through the support 11. The end of the first water pipe 32 near the support 11 is fixedly connected to the support 11. The three diverters 31 are connected to the transmitter 22 in a triangular arrangement. The storage assembly 4 includes a water tank 41 located at the end of the first water pipe 32 away from the support 11, and a water inlet 42 fixedly connected to the upper end of the water tank 41. The extraction assembly 5 includes a water pump 51 fixedly connected to the outer side of the upper end of the water tank 41, and a water pump pipe 52 fixedly connected to the end of the water pump 51 near the water tank 41. The water pump pipe 52 is located away from the water pump 51. A water pump 51 is installed through the water tank 41, and a drain pipe 53 is fixedly connected to the end of the water pump 51 away from the water tank 41. The end of the drain pipe 53 away from the water pump 51 is fixedly connected to the first water pipe 32. The manifold assembly 6 includes a second water pipe 61 fixedly connected to the end of the transmitter 22 away from the distributor 31. The end of the second water pipe 61 away from the transmitter 22 passes through the bracket 11 and is fixedly connected to a manifold 62. The end of the manifold 62 near the bracket 11 is fixedly connected to the bracket 11. The end of the manifold 62 away from the bracket 11 is fixedly connected to a third water pipe 63. The end of the third water pipe 63 away from the manifold 62 is fixedly connected to the outer side of the middle of the water tank 41. The heat exchange assembly 7 includes the third water pipe 63. A heat exchanger 71 is fitted on the outer side of the middle section, and connecting pipes 72 are fixedly connected to both sides of the end of the heat exchanger 71 away from the third water pipe 63. The cooling component 8 includes a radiator 81 and a cooler 82 fixedly connected to the end of the connecting pipe 72 away from the heat exchanger 71, and a delivery pipe 83 is fixedly connected to the end of the radiator 81 away from the connecting pipe 72. The end of the delivery pipe 83 away from the radiator 81 is fixedly connected to the cooler 82. The water pump 51 is started to draw coolant from the water tank 41 through the water pumping pipe 52. The drawn coolant is injected into the first water pipe 32 through the drain pipe 53, and then after being divided by the first water pipe 32, it is injected into the three sets of transmitters 22 for further diversion. After being diverted again by the transmitter 22, the coolant is sequentially injected into the guide tube 21 to dissipate heat from the attached membrane substrate. The coolant that has absorbed heat then flows through another set of transmitters 22 and into the second water pipe 61. After flowing through the second water pipe 61, it flows into the manifold 62 and then into the third water pipe 63. While flowing in the third water pipe 63, the coolant exchanges heat with the coolant sprayed from the cooler 82 through the heat exchanger 71. The cooled coolant then enters the radiator 81 to dissipate heat and then flows into the cooler 82 through the delivery pipe 83 for cooling. The cooled coolant is then injected into the water tank 41 for reuse.

[0031] Working principle: During the extrusion production of the extruded film sheet, the extruded film sheet is first passed through multiple sets of guide cylinders 21 and guide rollers 26 in sequence, and then pulled by an external traction winding device. Subsequently, multiple sets of electric telescopic rods 23 are activated. After the electric telescopic rods 23 are activated, the output shaft drives the first connecting plate 24 and the second connecting plate 25 to move downward, thereby allowing the second connecting plate 25 to drive the guide rollers 26 to move downward and press down on the film sheet, so that the film sheet can fit more tightly with the guide cylinders 21. Then, the water pump 51 is activated to draw coolant from the water tank 41 through the water pipe 52. The drawn coolant is injected into the first water pipe 32 through the drain pipe 53, and then after being divided by the first water pipe 32, it is injected into the water tank 41. The coolant is further divided within the three sets of transmitters 22. After being divided by the transmitters 22, the coolant is sequentially injected into the guide cylinder 21 to dissipate heat from the attached membrane sheet. The coolant that has absorbed heat then flows through another set of transmitters 22 and into the second water pipe 61. After flowing through the second water pipe 61, it flows into the manifold 62 and then into the third water pipe 63. While flowing in the third water pipe 63, the coolant exchanges heat with the coolant sprayed from the coolant 82 through the heat exchanger 71. The cooled coolant then enters the radiator 81 to dissipate heat and then flows into the coolant 82 through the delivery pipe 83 for cooling. The cooled coolant is then injected into the water tank 41 for reuse.
