[0004] The above-mentioned related technologies have the following defects: the hot pressing device and the cooling device are independently arranged in pairs, and are arranged in a symmetrical manner. After the film is heated by the hot pressing device, it is separated from the hot pressing device and transported for a distance before entering the cooling device. The temperature loss in the intermediate transportation distance is relatively large, that is, the temperature difference in the cooling process of the film material is not maximized, so it needs to be improved. Summary of the invention

[0005] In order to reduce the temperature loss of a film material during the process of being transported to a cooling place after hot pressing, the present application provides a film material hot pressing processing equipment.

[0006] The present application provides a film material hot pressing processing equipment adopts the following technical solution: A film material hot pressing processing equipment comprises a hot pressing device, a cooling device and a winding device, wherein the cooling device is arranged below the hot pressing device, and the film material is cooled while being hot pressed between the hot pressing device and the cooling device and is finally wound up by the winding device, and the cooling device is provided with a cooling rack, and the cooling rack is slidably connected to an adjustment track, and the adjustment track is connected to an adjustment drive for adjusting the overlapping area of ​​the cooling device and the hot pressing device.

[0007] By adopting the above technical solution, the film material is first transported to the area where the hot pressing device does not overlap with the cooling device for heating; then it is transported to the overlapping area of ​​the hot pressing device and the cooling device, where it is heated on one side and cooled on the other side, and the temperature difference between the two sides is used to make the two pieces of film material easier to fit together; then the film material is transported to the part of the cooling device that extends out of the hot pressing device for simple cooling, and finally the cooled film material is rolled up by the winding device, eliminating the intermediate conveying stage from the traditional mode of independent heating, transportation, and independent cooling, and directly contacting the two sides of the film material with the hot pressing device, that is, the cooling device, to maximize the use of the temperature difference between the hot pressing device and the cooling device, reducing the temperature loss during the processing process, and making the processing effect of the film material better. In addition, by adjusting the overlapping area of ​​the cooling device and the hot pressing device using the adjustment drive, the length of the three processes of overall heating, double-sided temperature difference bonding, and cooling can be flexibly adjusted, so the adjustment efficiency is also higher, and each module does not need to be adjusted separately.

[0008] Optionally, it also includes a filling device, which includes a filling plate and a filling elastic member, and the filling elastic member is connected between the filling plate and the cooling frame so that the filling plate abuts against the area where the hot pressing device does not overlap with the cooling device.

[0009] By adopting the above technical solution, the filling plate can make the film material more closely fit the hot pressing device when it is transported to the part where the hot pressing device does not overlap with the cooling device, thereby improving the efficiency of the heating process. In addition, the filling device is connected to the cooling rack, so that the filling plate and the cooling device can be adjusted synchronously, and then all sections of the hot pressing device can be effectively utilized during the adjustment process.

[0010] Optionally, the filling device further comprises a filling shell having an opening, the filling plate is located at the opening, a temperature regulating device is arranged inside the filling shell, and a plurality of temperature variable plates are arranged on the side of the filling plate facing the inside of the filling shell.

[0011] By adopting the above technical scheme, the air temperature inside the filling shell can be adjusted by using a temperature regulating device, so that the temperature of the filling plate can be controlled. When the film material is transported between the hot pressing device and the filling plate, the temperature of the filling plate can be increased so that both sides of the film material are heated. The filling plate can also be cooled so that a small temperature difference is generated on both sides of the film material in advance, so that the subsequent film material can be directly preheated and precooled with a large temperature difference on both sides. This is equivalent to a processing process of transitioning a section of temperature difference on both sides in advance. Overall, the temperature of the filling plate is adjustable, so that the filling plate can be used for fine adjustment according to process needs.

[0012] Optionally, it also includes a conveying film and several filling rods, the conveying film is annular and is mounted on the outside of the filling rods, the filling device is located inside the conveying film, the filling shell is provided with an air supply pipe connected to its interior, and the air supply pipe extends from one end away from the filling shell to the filling rod.

[0013] By adopting the above technical solution, when the film material is transported between the filling plate and the hot pressing device, the film material will not directly contact the filling plate, but will contact the conveying film and drive the conveying film to move and rotate through friction, thereby reducing the wear of the film material during transportation. In addition, the air with a preset temperature inside the filling shell can also be transported to the filling rod, thereby reducing the temperature difference between the filling rod, the conveying film and the filling plate, reducing temperature loss, and providing feasibility for the conveying film to contact the film material instead of the filling plate.

[0014] Optionally, a variable temperature groove is arranged on the outer side of the filling roller, and the inner diameter width of the variable temperature groove increases in the direction away from the notch.

[0015] By adopting the above technical solution, the temperature variable tank can increase the specific surface area of ​​the filling rod, thereby making the contact area between the filling rod and the surrounding air larger, so the temperature change effect is also better, and the temperature difference between the filling rod and the filling plate can be reduced more quickly.

[0016] Optionally, the replacement plate and the temperature-changing plate are provided with reserved holes, and the replacement shell is provided with an air supply fan at the connection between the replacement shell and the air supply pipe.

[0017] By adopting the above technical scheme, a small degree of negative pressure can be formed inside the replacement shell when the air supply fan draws away the air of the prefabricated temperature inside the replacement shell, and then the membrane material can be adsorbed on the replacement plate through the reserved holes. Correspondingly, materials such as powders temporarily attached to the surface of the membrane material as needed during the processing can also be more stably adsorbed on the membrane material. The membrane material and the conveying film itself are also breathable materials.

[0018] Optionally, a powder feeding device is also included, which includes a powder feeding shell having a powder outlet and a vibration device connected to the powder feeding shell, and the powder outlet is located above the filling plate.

[0019] By adopting the above technical solution, powder can be added between two or more membrane materials according to product needs, thereby increasing the diversity of product production options.

[0020] Optionally, the powder feeding shell is provided with an adjustment hole near the powder outlet, an adjustment plate is slidably arranged in the adjustment hole, and the powder feeding shell is provided with an adjustment component for controlling the extent to which the adjustment plate extends into the powder feeding shell.

[0021] By adopting the above technical solution, the actual flow rate of the powder can be controlled by adjusting the powder flow cross-sectional area intercepted by the adjustment plate using the adjustment component. Under the condition of consistent conveying speed of the membrane material, the dosage of the powder can be adjusted in this way.

[0022] Optionally, the adjustment assembly includes a support rod, a support hole is provided at the bottom of the powder feeding shell, the support rod is threadedly connected to the support hole, and the top of the support rod abuts against the bottom of the adjustment plate; The powder feeding shell is also provided with a downward pressing elastic belt, the two ends of which are connected to the powder feeding shell and the middle part of which abuts against the top of the adjusting plate.

[0023] By adopting the above technical solution, the support rod supports the bottom of the adjustment plate, and the downward elastic band presses down the top of the adjustment plate stably. Overall, the position of the adjustment plate can be adjusted and the influence of the vibration device on the stability of the adjustment plate can be reduced, thereby reducing the "bounce" of the adjustment plate and improving the uniformity of the powder during the production process.

[0024] Optionally, an elastic heat-insulating sleeve is provided between the filling plate and the filling shell to seal the gap therebetween. By adopting the above technical solution, the temperature loss inside the replacement shell can be further reduced, which is more energy-efficient.

[0025] In summary, the present application includes at least one of the following beneficial effects: 1. The film material is first transported to the area where the hot pressing device does not overlap with the cooling device for heating; then it is transported to the overlapping area of ​​the hot pressing device and the cooling device, where it is heated on one side and cooled on the other side, and the temperature difference between the two sides makes it easier for the two pieces of film material to fit together; then the film material is transported to the part of the cooling device that extends out of the hot pressing device for simple cooling, and finally the cooled film material is rolled up by the winding device, eliminating the intermediate conveying stage from the traditional mode of independent heating, transportation, and independent cooling, and directly contacting both sides of the film material with the hot pressing device, that is, the cooling device, to maximize the use of the temperature difference between the hot pressing device and the cooling device, reducing the temperature loss during the processing process, and making the processing effect of the film material better. In addition, by adjusting the overlapping area of ​​the cooling device and the hot pressing device using the adjustment drive, the length of the three processes of overall heating, double-sided temperature difference bonding, and cooling can be flexibly adjusted, so the adjustment efficiency is also higher, and there is no need to adjust each module separately.

[0026] 2. The filling plate can make the film material fit more closely with the hot pressing device when it is transported to the part where the hot pressing device does not overlap with the cooling device, thereby improving the efficiency of the heating process. In addition, the filling device is connected to the cooling rack, so that the filling plate and the cooling device can be adjusted synchronously, and then all sections of the hot pressing device can be effectively utilized during the adjustment process.

[0027] 3. When the air supply fan extracts the air of the pre-temperature inside the filling shell, a small negative pressure can be formed inside the filling shell, and then the membrane material can be adsorbed on the filling plate through the reserved holes. Correspondingly, materials such as powders temporarily attached to the surface of the membrane material as needed during the processing can also be more stably adsorbed on the membrane material. The membrane material and the conveying membrane itself are also breathable materials. BRIEF DESCRIPTION OF THE DRAWINGS

By adjusting the overlapping area, the detailed process requirements of different film material processing and production can be adjusted.

[0034] Reference Figure 3The powder feeding device 5 includes a powder feeding shell 51, and powder can be added to the top of the powder feeding shell 51. A powder outlet 510 is provided at the position of the powder feeding shell 51 near the intersection of the two film materials. The powder feeding shell 51 at the powder outlet 510 is a flat structure extending out. A vibration device 52 is installed at the bottom of the powder feeding shell 51 to continuously transport the powder inside the powder feeding shell 51 toward the powder outlet 510. An adjustment hole 530 is provided at the top of the powder feeding shell 51 near the powder outlet 510. The adjustment hole 530 is a square hole. An adjustment plate 53 is inserted in the adjustment hole 530, and the adjustment plate 53 can slide up and down in the adjustment hole 530 to use the adjustment plate 53 to adjust the cross-sectional area that can actually be supplied with powder. The powder feeding housing 51 is also provided with an adjustment component for controlling the extent to which the adjustment plate 53 extends into the powder feeding housing 51. The adjustment component includes a support rod 54 and a downward-pressing elastic band 55. A support hole 540 is provided at the bottom of the powder feeding housing 51. The support rod 54 is threadedly connected to the support hole 540 and the top of the support rod 54 abuts against the bottom of the adjustment plate 53. The depth of the adjustment plate 53 can be adjusted by adjusting the height of the top of the support rod 54. Both ends of the downward-pressing elastic band 55 are fixed to the powder feeding housing 51, and the middle part abuts against the top of the adjustment plate 53 to press down the adjustment plate 53, so as to reduce the influence of the vibration device 52 on the position stability of the adjustment plate 53.

[0035] Reference Figure 4 The replacement device 6 includes a replacement shell 61 with an opening, a replacement plate 62 is arranged at the opening, and a replacement elastic member 63 is fixedly arranged between the replacement plate 62 and the replacement shell 61. The replacement elastic member 63 in this embodiment is specifically a spring to push the replacement plate 62 toward the hot pressing device 2, so that the film material and the hot pressing device 2 can fit more closely and the heating effect is better.

[0036] A temperature regulating device 64 is also provided inside the replacement shell 61, and a temperature control unit is built in the temperature regulating device 64 to regulate the temperature of the replacement plate 62. The mechanism of action of the temperature regulating device 64 is to regulate the temperature inside the replacement shell 61 and then act on the replacement plate 62. Therefore, an elastic heat-insulating sleeve 65 is also provided between the replacement plate 62 and the replacement shell 61. The elastic heat-insulating sleeve 65 can be made of a flexible material such as rubber to cover the gap between the replacement plate 62 and the replacement shell 61.

A conveying film 67 is arranged around the outer side of the positioning shell 61 and the plurality of positioning rods 66. The conveying film 67 is made of breathable material, and the positioning plate 62 is also located inside the conveying film 67. When the film material passes through the overlapping part of the positioning plate 62 and the hot pressing device 2, the conveying film 67 can be driven to rotate, thereby reducing the friction between the positioning plate 62 and the film material.

[0038] Reference Figure 4 and Figure 5 The side of the filling plate 62 facing the inside of the filling shell 61 is integrally formed with a plurality of temperature-changing plates 621, and the filling plate 62 is provided with reserved holes 622 at the temperature-changing plates 621.

The air supply fan 69 is used to transport the air inside the filling shell 61 to the outside to a small extent, and can also form a negative pressure at the filling plate 62. The membrane material itself also has a certain air permeability, so that the powder can be more closely adsorbed to the membrane material below.

[0039] Reference Figure 4 and Figure 6 , the air supply pipe 68 generates several branches at one end away from the replacement shell 61 and extends to several replacement rods 66 respectively. Several temperature-changing grooves 660 are evenly distributed along the circumference on the outside of the replacement rod 66, and each temperature-changing groove 660 is arranged parallel to the axial direction of the replacement rod 66. In addition, the inner diameter width of the temperature-changing groove 660 increases along the direction away from the notch, that is, the width at the notch is smaller, and the width at the bottom of the groove is larger. The air inside the replacement shell 61 can be transported to several replacement rods 66 in a small range. The temperature-changing grooves 660 increase the specific surface area of ​​the replacement rod 66 so that it is easier to change temperature, thereby reducing the temperature difference between the several replacement rods 66 and the transmission film 67 outside the several replacement rods 66 and the replacement plate 62, so that the temperature loss in the process of the transmission film 67 transferring the temperature of the replacement plate 62 to the film material is small.
