[0002] PVC packaging film is widely used in many fields such as food and daily necessities due to its good flexibility, transparency and barrier properties. In the production and processing of PVC packaging film, the cooling process is a crucial link. The temperature of the extruded PVC packaging film is high and needs to be quickly cooled and shaped to ensure its dimensional stability, physical properties and appearance quality.

[0003] However, the existing PVC packaging film cooling device has some shortcomings in practical applications. For example, the problem of uneven cooling is relatively common, which will lead to inconsistent shrinkage rates in different parts of the packaging film, thereby affecting the flatness of the packaging film and subsequent processing performance. Summary of the invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A PVC packaging film processing cooling device, comprising: a cooling component, the cooling component is used for packaging film extension cooling, a first motor is fixedly installed on one side of the outer surface of the cooling component, and a guide shaft is fixedly installed on the output end of the first motor;

[0005] A protection component, which is used for buffering support when the packaging film is stretched, and a groove plate is fixedly installed on the outer surface of the protection component;

[0006] A guide assembly, which is used for guiding the packaging film to prevent deviation, a second motor is fixedly installed at the top side of the guide assembly, and a winding shaft is fixedly installed at the output end of the second motor;

[0007] The slot plate is fixedly installed inside the cooling assembly, and the protective assembly is fixedly installed on the top of the cooling assembly through the slot plate. There are two protective assemblies, which are symmetrically arranged with the slot plate as the center, and the guide assembly is fixedly installed on the top side of the cooling assembly. Before the PVC packaging film is cooled, the staff transports the extruded high-temperature packaging film to one side of the guide shaft, and makes the end of the packaging film pass from the bottom of the guide shaft, and then pulls the packaging film through the protective assembly to extend into the guide assembly, so that the packaging film is wrapped around the surface of the winding shaft to position and wind the packaging film when it is cooled. When the PVC packaging film is cooled, the staff starts the motor and the cooling fan so that the output end of the first motor drives the guide shaft to rotate to transport the packaging film, and the stretched and extended packaging film is then The film is rolled up as the winding shaft rotates and slides from the outside of the cooling component. At this time, the cold air blown by the air cooler through the exhaust port performs preliminary cooling of the packaging film over a large area. When the packaging film is rolled up, it passes through the slot plate and rubs against the protective component fixed on the slot plate surface, so as to protect the rolled and stretched packaging film and prevent the packaging film from being blown by the wind and rubbing against the slot plate surface along the wind direction when the cold air flow blows the packaging film, causing the slot plate side to wear the packaging film. After the preliminary cooling treatment, the packaging film rubs against the surface of the guide component as the winding shaft rolls up. The guide component is configured as a double-layer hollow structure, and a cooling medium is provided for flowing inside the cavity, so that when the packaging film passes through the guide component, the heat on the packaging film is transferred to the surface of the guide component, and the packaging film is evenly cooled through the circulation exchange of cold and hot media.

[0008] Wherein, the guide assembly includes a positioning frame, which is fixedly installed on the top side of the cooling assembly, and a limiting shaft is rotatably installed between the opposite surfaces of the positioning frame, and the limiting shaft is arranged on a side of the positioning frame close to the second motor, and an anti-deflection assembly is fixedly installed on the surface of the limiting shaft close to the slot plate. In order to speed up the cooling speed of the packaging film and cool the packaging film into shape, the packaging film needs to be extended and unfolded during the processing and cooling of the packaging film. Since the packaging film is relatively flexible, an anti-deflection component is provided on the outside of the shaft shell to prevent the side of the packaging film from shifting when the packaging film is rolled up. When the packaging film slides and displaces from the surface of multiple shaft shells, the two sides of the packaging film are limited to avoid the deviation of the packaging film during transportation and affect the flatness of the packaging film during winding; and when the packaging film slides on the surface of the shaft shell, the metal shaft shell has good thermal conductivity, and a cooling medium flows and is transported in the uniform cooling member provided in the shaft shell to cool the heat absorbed by the shaft shell. At this time, the packaging film in contact with the multiple shaft shells is uniformly cooled and cooled to form; the formed packaging film slides on the limiting shaft and is guided to be wrapped around the surface of the winding shaft to complete the cooling process.

[0009] Preferably, the anti-deviation components are provided in three groups, and the three groups of anti-deviation components are symmetrically arranged with the positioning frame as the center, and a shaft shell is rotatably installed between the opposite surfaces of the anti-deviation components, and a uniform cooling part is fixedly installed inside the shaft shell.

[0010] Preferably, the anti-deviation assembly comprises a sleeve shaft, a sleeve ring is fixedly mounted on the surface of the sleeve shaft, and a first bent rod and a second bent rod are respectively fixedly mounted on the outer surface of the sleeve ring.

[0011] Preferably, the surfaces of the first curved rod and the second curved rod are fixedly mounted with short rods, and the outer surfaces of the short rods are fixedly mounted with extrusion sheets, which are made of flexible material and frictionally fit with the side edges of the packaging film. Rings are arranged on both sides of the shaft shell, and when the packaging film slides on the surface of the shaft shell and deviates, the extrusion sheets connected to the first curved rod and the second curved rod limit and correct the side edges of the packaging film, so as to reduce the deviation amplitude of the packaging film and prevent the packaging film from falling off the shaft shell when winding, which affects the subsequent processing of the packaging film.

[0012] Preferably, the uniform cooling member includes a drainage tube, the outer surface of which is sheathed with an inner shell, two inner shells are provided, the outer surfaces of the two inner shells are sheathed with baffles, the outer surfaces of the baffles are sheathed with an outer shell, and a center plate is fixedly installed in the middle of the inner shell. The staff injects the cooling medium into the inner shell through one end of the drainage tube, and the cooling medium is filled in the inner shell. At this time, the segmented drainage tube allows the cooling medium to be injected into the outer shell. As the cooling medium is continuously injected, the two inner shells in the outer shell are injected with the cooling medium. When the packaging film contacts the shaft shell and conducts heat, the baffles sheathed on the surface of the inner shell transfer the heat absorbed by the shaft shell to the surface of the inner shell. At this time, the cooling medium absorbs the heat and discharges it from the drainage tube at the other end, thereby completing the exchange of cold and hot media and uniformly cooling the packaging film.

[0013] Preferably, external tubes are fixedly installed on both sides of the outer surface of the outer shell, the external tubes are sleeved on the outer surface of the drainage tube, the drainage tube passes through the sleeve shaft and extends to the outside thereof, and the sleeve ring is fixedly connected to the drainage tube through the sleeve shaft.

[0014] Preferably, the cooling assembly includes a support seat, a frame plate is fixedly mounted on the top of the support seat, a snap-on frame is fixedly mounted on the outer surface of the frame plate, a cooler is fixedly mounted on the outer side of the snap-on frame, and an exhaust port is provided on the surface of the cooler. The staff starts the cooler so that the cold air flow generated by the cooler is discharged along the exhaust port. Since the PVC packaging film is relatively flexible, the packaging film that is rolled up and moved from the outer side of the exhaust port is blown by the cold air flow. Affected by the properties of its material, the packaging film is blown toward one side of the protective assembly. At this time, the rolled up packaging film slides and moves on the surface of the protective assembly. The packaging film is initially cooled over a large area through the cooperation between the cooler and the protective assembly, while preventing the packaging film from being deformed due to excessive blowing force.

[0015] Preferably, the protection component comprises a clamping plate, a limiting pad is fixedly mounted on the lower surface of the clamping plate, a bottom support plate is fixedly mounted on the lower surface of the limiting pad, and a limiting block is fixedly mounted between the limiting pad and the bottom support plate.

The packaging film moving in the direction of the wind under the wind generates friction with the surface of the curved sliding sheet, and as the winding shaft rotates, the packaging film slides and displaces on the outside of the curved sliding sheet, and the corrugated plate of the flexible structure is deformed when affected by the pulling of the winding packaging film, thereby supporting and protecting the winding packaging film, and preventing the packaging film from being damaged due to excessive bulging caused by the blowing.

[0017] Preferably, the clamping plate and the bottom support plate are respectively fixedly mounted on both sides of the outer surface of the slot plate, an inner support shaft is fixedly mounted between the opposite surfaces of the clamping plate and the bottom support plate, and positioning plates are fixedly mounted on both sides of the outer surface of the inner support shaft.

[0018] The present invention provides a PVC packaging film processing cooling device, which has the following beneficial effects:

[0019] 1. The PVC packaging film processing and cooling device generates friction between the packaging film that is blown by the wind and moves in the direction of the wind and the surface of the curved sliding plate. As the winding shaft rotates, the packaging film slides and moves on the outside of the curved sliding plate. The corrugated plate with a flexible structure is deformed when it is pulled by the wound packaging film, thereby supporting and protecting the wound packaging film to prevent the packaging film from being damaged due to excessive bulging caused by the blowing.

[0020] 2. The PVC packaging film processing and cooling device is clamped on the outer side of the groove plate through the clamping plate and the bottom support plate, and the inner support shaft is mounted inside the clamping plate and the bottom support plate through the positioning plate, and the clamping plate is reinforced and supported by the inner support shaft.

[0021] 3. The PVC packaging film processing cooling device starts the air cooler through the staff, so that the cold air flow generated by the air cooler is discharged along the exhaust port. Since the PVC packaging film is relatively flexible, the packaging film that is rolled up and moved from the outside of the exhaust port is blown by the cold air flow. Affected by its material properties, the packaging film is blown toward the side of the protective component. At this time, the rolled up packaging film slides and moves on the surface of the protective component. The cold air fan and the protective component cooperate to initially cool down the packaging film over a large area, while preventing the packaging film from being deformed by excessive blowing force.

[0022] 4. The PVC packaging film processing cooling device is configured such that the staff injects the cooling medium for cooling into the inner shell through one end of the drainage pipe. At this time, the cooling medium is filled in the inner shell. At this time, the segmented drainage pipe allows the cooling medium to be injected into the outer shell. As the cooling medium is continuously injected, the two inner shells in the outer shell are injected with the cooling medium. When the packaging film contacts the shaft shell and conducts heat, the baffles mounted on the surface of the inner shell transfer the heat absorbed by the shaft shell to the surface of the inner shell. At this time, the cooling medium absorbs the heat and is discharged from the drainage pipe at the other end, thereby completing the exchange of hot and cold media and evenly cooling the packaging film.

[0023] 5. The PVC packaging film processing and cooling device is provided with sleeve rings on both sides of the shaft shell. When the packaging film slides on the surface of the shaft shell and deviates, the extrusion sheet connected to the first bending rod and the second bending rod limits and corrects the side edge of the packaging film to reduce the deviation amplitude of the packaging film and prevent the packaging film from falling off the shaft shell when winding, affecting the subsequent processing of the packaging film.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The first embodiment, as Figures 1 to 3 As shown, the present invention provides a technical solution: a PVC packaging film processing cooling device, comprising: a cooling component 3, the cooling component 3 is used for packaging film extension cooling, a first motor 5 is fixedly installed on one side of the outer surface of the cooling component 3, and a guide shaft 8 is fixedly installed on the output end of the first motor 5;

[0039] A protection component 2, which is used for buffering support when the packaging film is stretched, and a groove plate 1 is fixedly installed on the outer surface of the protection component 2;

[0040] A guide assembly 4, which is used for guiding the packaging film to prevent deviation, a second motor 7 is fixedly mounted on the top side of the guide assembly 4, and a winding shaft 6 is fixedly mounted on the output end of the second motor 7;

[0041] The slot plate 1 is fixedly installed inside the cooling component 3, and the protective component 2 is fixedly installed on the top of the cooling component 3 through the slot plate 1. There are two protective components 2, and the two protective components 2 are symmetrically arranged with the slot plate 1 as the center. The guide component 4 is fixedly installed on the top side of the cooling component 3; before the PVC packaging film is cooled, the staff transports the extruded high-temperature packaging film to one side of the guide shaft 8, and makes the end of the packaging film pass from the bottom of the guide shaft 8, and then pulls the packaging film through the protective component 2 to extend into the guide component 4, so that the packaging film is wrapped around the surface of the winding shaft 6, so as to position and wind the packaging film when the packaging film is cooled; when the PVC packaging film is cooled, the staff starts the motor and the cooling fan 31, so that the output end of the first motor 5 drives the guide shaft 8 to rotate, and transports the packaging film, at which time the stretching and extension are performed. The packaging film is rolled up as the winding shaft 6 rotates and slides from the outside of the cooling component 3. At this time, the cold air blown by the cold air fan 31 through the exhaust port 32 performs a large-scale preliminary cooling of the packaging film. When the packaging film is rolled up, it passes through the slot plate 1 and rubs against the protective component 2 fixed on the surface of the slot plate 1, so as to protect the rolled and stretched packaging film and prevent the packaging film from being blown by the wind and rubbing against the surface of the slot plate 1 along the wind direction when the cold air flow blows the packaging film, causing the side of the slot plate 1 to wear the packaging film. After the preliminary cooling treatment, the packaging film rubs against the surface of the guide component 4 as the winding shaft 6 is rolled up. The guide component 4 is set to a double-layer hollow structure, and a cooling medium is set to flow inside the cavity, so that when the packaging film passes through the guide component 4, the heat on the packaging film is transferred to the surface of the guide component 4, and the packaging film is evenly cooled by the circulation exchange of cold and hot media.

[0042] The second embodiment is based on the first embodiment. Figures 4 to 8As shown, the guide assembly 4 includes a positioning frame 41, and the positioning frame 41 is fixedly installed at the top side of the cooling assembly 3. A limiting shaft 43 is rotatably installed between the opposite surfaces of the positioning frame 41, and the limiting shaft 43 is arranged on the side of the positioning frame 41 close to the second motor 7. An anti-deflection assembly 44 is fixedly installed on the surface of the limiting shaft 43 close to the slot plate 1. In order to accelerate the cooling speed of the packaging film and cool and shape the packaging film, the packaging film needs to be extended and unfolded during the processing and cooling of the packaging film. Since the packaging film is relatively flexible, an anti-deflection component 44 is provided on the outside of the shaft shell 42 to prevent the side edge of the packaging film from shifting when the packaging film is rolled up. When the packaging film slides and displaces from the surface of the multiple groups of shaft shells 42, the two sides of the packaging film are limited to avoid the deviation of the packaging film during transportation and affect the flatness of the packaging film during winding; and when the packaging film slides on the surface of the shaft shell 42, the metal shaft shell 42 has good thermal conductivity, and a cooling medium flows and is transported in the uniform cooling member 45 provided in the shaft shell 42 to cool the heat absorbed by the shaft shell 42. At this time, the packaging film in contact with the multiple groups of shaft shells 42 is uniformly cooled and cooled to form; the formed packaging film is slid and guided on the limiting shaft 43 to be wound on the surface of the winding shaft 6 to complete the cooling process.

[0043] The anti-deviation components 44 are provided in three groups, and the three groups of the anti-deviation components 44 are symmetrically arranged with the positioning frame 41 as the center. The shaft shell 42 is rotatably installed between the opposite surfaces of the anti-deviation components 44, and the uniform cooling member 45 is fixedly installed inside the shaft shell 42.

[0044] The anti-deviation assembly 44 includes a sleeve shaft 443 , a collar 441 is fixedly mounted on the surface of the sleeve shaft 443 , and a first curved rod 442 and a second curved rod 445 are fixedly mounted on the outer surface of the collar 441 .

[0045] The surfaces of the first curved rod 442 and the second curved rod 445 are fixedly mounted with short rods 446, and the outer surfaces of the short rods 446 are fixedly mounted with extrusion sheets 444, which are made of flexible material and are frictionally matched with the side edges of the packaging film. The collars 441 are arranged on both sides of the shaft shell 42, and when the packaging film slides on the surface of the shaft shell 42 and deviates, the extrusion sheets 444 connected to the first curved rod 442 and the second curved rod 445 correct the side edges of the packaging film to reduce the deviation of the packaging film and prevent the packaging film from falling off the shaft shell 42 when winding, which affects the subsequent processing of the packaging film.

[0046] The uniform cooling member 45 includes a drainage tube 454, the outer surface of which is sleeved with an inner shell 453. Two inner shells 453 are provided. The outer surfaces of the two inner shells 453 are sleeved with baffles 452. The outer surfaces of the baffles 452 are sleeved with an outer shell 451. A center plate 455 is fixedly installed in the middle of the inner part of the outer shell 451. The staff injects the cooling medium for cooling into the inner shell 453 through one end of the drainage pipe 454. At this time, the cooling medium fills the inner shell 453. At this time, the segmented drainage pipe 454 injects the cooling medium into the outer shell 451. As the cooling medium is continuously injected, the two inner shells 453 in the outer shell 451 are injected with the cooling medium. When the packaging film contacts the shaft shell 42 and conducts heat, the baffle 452 mounted on the surface of the inner shell 453 transfers the heat absorbed by the shaft shell 42 to the surface of the inner shell 453. At this time, the cooling medium absorbs the heat and discharges it from the drainage pipe 454 at the other end, thereby completing the exchange of hot and cold media and evenly cooling the packaging film.

[0047] External tubes 456 are fixedly installed on both sides of the outer surface of the outer shell 451. The external tubes 456 are sleeved on the outer surface of the drainage tube 454. The drainage tube 454 extends to the outside through the sleeve shaft 443. The sleeve ring 441 is fixedly connected to the drainage tube 454 through the sleeve shaft 443.

[0048] The third embodiment is based on the first and second embodiments. Figures 9 to 12 As shown, the cooling assembly 3 includes a support seat 34, a frame plate 33 is fixedly installed on the top of the support seat 34, a clamping frame 35 is fixedly installed on the outer surface of the frame plate 33, a cooling fan 31 is fixedly installed on the outer side of the clamping frame 35, and an exhaust port 32 is opened on the surface of the cooling fan 31. The staff starts the cooling fan 31, so that the cold air flow generated by the cooling fan 31 is discharged along the exhaust port 32. Since the PVC packaging film is relatively flexible, the packaging film that is rolled up and moved from the outer side of the exhaust port 32 is blown by the cold air flow. Affected by its material properties, the packaging film is blown toward the side of the protective assembly 2. At this time, the rolled up packaging film slides and moves on the surface of the protective assembly 2. The cooling fan 31 cooperates with the protective assembly 2 to initially cool down the packaging film over a large area, while preventing the packaging film from being deformed by excessive blowing force.

[0049] The protection assembly 2 includes a clamping plate 21 , a limit pad 26 is fixedly installed on the lower surface of the clamping plate 21 , a bottom support plate 23 is fixedly installed on the lower surface of the limit pad 26 , and a limit block 29 is fixedly installed between the limit pad 26 and the bottom support plate 23 .

[0050] A bonding plate 27 is fixedly mounted on the top of the clamping plate 21, and a curved sliding sheet 25 is fixedly mounted on the outer surface of the bonding plate 27. The curved sliding sheet 25 is frictionally matched with the packaging film, and a corrugated plate 24 is provided on the surface of the bonding plate 27. The bonding plate 27 is clamped and matched with the bottom support plate 23 through the corrugated plate 24. The packaging film that moves in the direction of the wind under the wind generates friction with the surface of the curved sliding sheet 25. As the winding shaft 6 rotates, the packaging film slides and displaces outside the curved sliding sheet 25. The corrugated plate 24 with a flexible structure is deformed when it is pulled by the winding packaging film, thereby supporting and protecting the winding packaging film, and preventing the packaging film from being damaged due to excessive swelling caused by the blowing.

[0051] The clamping plate 21 and the bottom support plate 23 are respectively fixedly mounted on both sides of the outer surface of the slot plate 1, and an inner support shaft 28 is fixedly mounted between the opposite surfaces of the clamping plate 21 and the bottom support plate 23, and positioning plates 22 are fixedly mounted on both sides of the outer surface of the inner support shaft 28. The clamping plate 21 and the bottom support plate 23 are clamped on the outer side of the slot plate 1, and the inner support shaft 28 is mounted inside the clamping plate 21 and the bottom support plate 23 through the positioning plate 22, and the clamping plate 21 is reinforced and supported by the inner support shaft 28.

[0052] When in use, before the PVC packaging film is cooled, the staff will convey the extruded high-temperature packaging film to one side of the guide shaft 8, and make the end of the packaging film pass through the bottom of the guide shaft 8, and then pull the packaging film through the protective component 2 to extend into the guide component 4, so that the packaging film is wrapped around the surface of the winding shaft 6, so as to position and reel the packaging film when the packaging film is cooled; when the PVC packaging film is cooled, the staff will start the motor and the cooling fan 31, so that the output end of the first motor 5 drives the guide shaft 8 to rotate, and convey the packaging film. At this time, the stretched and extended packaging film is reeled up with the rotation of the winding shaft 6 and slides through the outside of the cooling component 3. At this time, the cold air blown out by the cooling fan 31 through the exhaust port 32 is applied to the packaging film. Perform preliminary cooling over a large area; when the packaging film is rolled up, it passes through the slot plate 1 and rubs against the protective component 2 fixed on the surface of the slot plate 1 to protect the rolled and stretched packaging film, so as to prevent the packaging film from being blown by the cold air flow and being blown by the wind and rubbing against the surface of the slot plate 1 along the wind direction, causing the side of the slot plate 1 to wear the packaging film; after the preliminary cooling treatment, the packaging film rubs against the surface of the guide component 4 as the winding shaft 6 is wound up, and the guide component 4 is configured as a double-layer hollow structure, and a cooling medium is provided for flowing inside the cavity, so that when the packaging film passes through the guide component 4, the heat on the packaging film is transferred to the surface of the guide component 4, and the packaging film is evenly cooled through the circulation exchange of cold and hot media.

[0053] Among them, the guide assembly 4 includes a positioning frame 41, which is fixedly installed at the top side of the cooling assembly 3, and a limiting shaft 43 is rotatably installed between the opposite surfaces of the positioning frame 41, and the limiting shaft 43 is arranged on the side of the positioning frame 41 close to the second motor 7, and an anti-bias assembly 44 is fixedly installed on the surface of the limiting shaft 43 close to the slot plate 1. In order to accelerate the cooling speed of the packaging film and cool and shape the packaging film, the packaging film needs to be extended and unfolded during the processing and cooling of the packaging film. Since the packaging film is relatively flexible, an anti-deflection component 44 is provided on the outside of the shaft shell 42 to prevent the side edge of the packaging film from shifting when the packaging film is rolled up. When the packaging film slides and displaces from the surface of the multiple groups of shaft shells 42, the two sides of the packaging film are limited to avoid the deviation of the packaging film during transportation and affect the flatness of the packaging film during winding; and when the packaging film slides on the surface of the shaft shell 42, the metal shaft shell 42 has good thermal conductivity, and a cooling medium flows and is transported in the uniform cooling member 45 provided in the shaft shell 42 to cool the heat absorbed by the shaft shell 42. At this time, the packaging film in contact with the multiple groups of shaft shells 42 is uniformly cooled and cooled to form; the formed packaging film is slid and guided on the limiting shaft 43 to be wound on the surface of the winding shaft 6 to complete the cooling process.

[0054] The staff starts the cold air fan 31, so that the cold air flow generated by the cold air fan 31 is discharged through the exhaust port 32. Since the PVC packaging film is relatively flexible, the packaging film that is rolled up and moved from the outside of the exhaust port 32 is blown by the cold air flow. Affected by its material properties, the packaging film is blown toward the side of the protective component 2. At this time, the rolled up packaging film slides and moves on the surface of the protective component 2. The cold air fan 31 and the protective component 2 cooperate to perform a large-area preliminary cooling of the packaging film, while preventing the packaging film from being deformed by excessive blowing force.

[0055] The packaging film moved in the direction of the wind under the influence of wind generates friction with the surface of the curved sliding piece 25. As the winding shaft 6 rotates, the packaging film slides and moves on the outside of the curved sliding piece 25. The corrugated plate 24 with a flexible structure is deformed when affected by the pulling of the wound packaging film, thereby supporting and protecting the wound packaging film to prevent the packaging film from being damaged due to excessive bulging caused by the blowing.

[0056] The clamping plate 21 and the bottom support plate 23 are clamped on the outer side of the groove plate 1 , and the inner support shaft 28 is mounted inside the clamping plate 21 and the bottom support plate 23 through the positioning plate 22 , and the clamping plate 21 is reinforced and supported by the inner support shaft 28 .

[0057] In order to accelerate the cooling speed of the packaging film and cool and shape the packaging film, the packaging film needs to be extended and unfolded during the processing and cooling of the packaging film. Since the packaging film is relatively flexible, an anti-deflection component 44 is provided on the outside of the shaft shell 42 to prevent the side edge of the packaging film from shifting when the packaging film is rolled up. When the packaging film slides and displaces from the surface of the multiple groups of shaft shells 42, the two sides of the packaging film are limited to avoid the deviation of the packaging film during transportation and affect the flatness of the packaging film during winding; and when the packaging film slides on the surface of the shaft shell 42, the metal shaft shell 42 has good thermal conductivity, and a cooling medium flows and is transported in the uniform cooling member 45 provided in the shaft shell 42 to cool the heat absorbed by the shaft shell 42. At this time, the packaging film in contact with the multiple groups of shaft shells 42 is uniformly cooled and cooled to form; the formed packaging film is slid and guided on the limiting shaft 43 to be wound on the surface of the winding shaft 6 to complete the cooling process.

[0058] The collar 441 is arranged on both sides of the shaft shell 42. When the packaging film slides on the surface of the shaft shell 42 and deviates, the extrusion sheet 444 connected to the first curved rod 442 and the second curved rod 445 limits and corrects the side edge of the packaging film to reduce the deviation amplitude of the packaging film and prevent the packaging film from falling off the shaft shell 42 when winding, affecting the subsequent processing of the packaging film.

[0059] The staff injects the cooling medium for cooling into the inner shell 453 through one end of the drainage pipe 454. At this time, the cooling medium fills the inner shell 453. At this time, the segmented drainage pipe 454 injects the cooling medium into the outer shell 451. As the cooling medium is continuously injected, the two inner shells 453 in the outer shell 451 are injected with the cooling medium. When the packaging film contacts the shaft shell 42 and conducts heat, the baffle 452 mounted on the surface of the inner shell 453 transfers the heat absorbed by the shaft shell 42 to the surface of the inner shell 453. At this time, the cooling medium absorbs the heat and discharges it from the drainage pipe 454 at the other end, thereby completing the exchange of hot and cold media and evenly cooling the packaging film.
