The conveying roller 120 is used for winding and conveying materials, the heating roller 180 is used for heating materials, and the tension adjusting roller 200 is used for adjusting the tension between the materials and the rollers.

[0034] In some specific embodiments of the present utility model, the number of the conveying rollers 120 can be multiple and in multiple layers. Thus, after the conveying rollers 120 are connected to an external driving device, the material coils wound on their surfaces can be conveyed.

[0035] In some specific embodiments of the present utility model, a heating roller 180 can be installed between the conveying rollers 120, which can heat the glue on the material film by the heating roller 180, thereby increasing its adhesion force.

[0036] In some specific embodiments of the present utility model, a tension adjusting roller 200 can be arranged between the conveying rollers 120, and the number of the tension adjusting rollers 200 is two, one above and one below. Thus, by adjusting the height of the tension adjusting roller 200, the pressure of the tension adjusting roller 200 on the material film can be changed, and further, the conveying tension of the material film can be changed.

[0037] In some specific embodiments of the present utility model, the heating roller 180 can include an electric heating strip 240, a fan 260 and a rotating frame 270. The electric heating strip 240 is used to heat the roller 180 to increase its surface temperature. The fan 260 is used for air replacement. The rotating frame 270 is used for adjusting the wind direction of the fan 260. Both sides of the heating roller 180 are rotatably connected with a connecting frame 170, and further, the dissipation of the hot air inside the heating roller 180 is accelerated.

[0038] Reference Figure 3 , in some specific embodiments of the present utility model, a plurality of electric heating strips 240 can be installed inside the heating roller 180, so that the electric heating strips 240 can be heated up after being connected to an external power supply, thereby heating the inner wall of the heating roller 180, and further, the heating roller 180 can have a heating effect.

[0039] Reference Figure 4 , in some specific embodiments of the present utility model, connecting frames 170 can be arranged at both ends of the heating roller 180, so that the heating roller 180 can rotate between the connecting frames 170. At the same time, a fan 260 can be arranged inside the connecting frames 170, so that the fan 260 can be turned on after being connected to the power supply, and the hot air inside the heating roller 180 communicated with the connecting frames 170 can be blown outwards, and further, the dissipation of the heat of the heating roller 180 is accelerated.

[0040] In some specific embodiments of the present utility model, a rotating frame 270 can be rotatably arranged on the inner wall of the connecting frame 170. Thus, the staff can rotate the rotating frame 270 to change the blowing direction of the fan 260 towards the inside of the heating roller 180, thereby accelerating the air replacement efficiency inside the heating roller 180.

[0041] Reference Figure 5 , in some specific embodiments of the present utility model, a plug-in slot 290 can be formed on one side of the rotating frame 270, and a fixing plate 280 is inserted inside the plug-in slot 290. The bottom of the fixing plate 280 is arc-shaped, and the driving part of the fan 260 is fixedly arranged on the upper half of the fixing plate 280.

[0042] In some specific embodiments of the present utility model, a fixing plate 280 can be provided on one side of the rotating frame 270, and the fan 260 can be fixed through the fixing plate 280. Thus, the fan 260 can perform the function of air replacement inside the heating roller 180.

[0043] In some specific embodiments of the present utility model, a plug-in slot 290 can be opened on one side of the rotating frame 270, and the base of the fixing plate 280 is arc-shaped, enabling the fixing plate 280 to be plugged into the rotating frame 270. Furthermore, the position of the fixing plate 280 can be limited. At the same time, a device for increasing sliding friction can be added between the fixing plate 280 and the plug-in slot 290, thereby enhancing the connection effect between the two.

[0044] In some specific embodiments of the present utility model, the base of the fixing plate 280 can be in contact with the inner wall of the connecting frame 170. Thus, the rotating frame 270 can rotate without external interference. At the same time, when the rotating frame 270 drives the fixing plate 280 to rotate, its intake elevation angle will change to a certain extent, but it will not affect the air replacement effect.

[0045] In summary, first, in this embodiment, by providing a plurality of conveying rollers 120, the conveying rollers 120 can convey the material film. At the same time, a tension adjusting roller 200 can be provided between the conveying rollers 120, thereby changing the tension of the material film during conveyance. At the same time, the tension adjusting roller 200 is an auxiliary station, thus providing an auxiliary effect for the conveyance of the material film.

[0046] Second, in this embodiment, by providing a heating roller 180, it can heat the material film in contact with it, thereby increasing the adhesion of the material film.

[0047] Furthermore, a fan 260 is provided on one side of the heating roller 180, so that the hot air inside the heating roller 180 can be quickly discharged by the fan 260, avoiding the situation where the surface of the heating roller 180 cannot be cooled in time when it is not needed, resulting in the risk of scalding for the staff when disassembling it.

[0048] In some specific embodiments of the present utility model, a cover 190 can be hinged on the side of the connecting frame 170 away from the heating roller 180, and the cover 190 is used to close the opening of the connecting frame 170.

[0049] It is easily understandable that in this embodiment, by providing a cover 190 which is hinged to the connecting frame 170, the opening of the heating roller 180 can be closed by using the cover 190, preventing the heat inside the heating roller 180 from radiating out through the opening of the connecting frame 170, which may lead to insufficient heating effect of the heating roller 180. When it is necessary to dissipate the heat inside the heating roller 180, the cover 190 can be manually opened to enable the hot air inside the heating roller 180 to be dissipated in a timely manner.

[0050] In some specific embodiments of the present utility model, support connection columns 100 can be threadedly screwed to both opposite sides of the upper half of the connecting frame 170 through fastening bolts. The number of support connection columns 100 is several, and the support connection columns 100 are used for the limited placement of different functional rollers.

[0051] It is easily understandable that in this embodiment, by providing fastening bolts on the upper half of the connecting frame 170, the connecting frame 170 can be threadedly screwed to the support connection columns 100 through the fastening bolts, thereby fixing its position. At the same time, telescopic ball columns are provided on both sides of the lower half of the connecting frame 170, which can further strengthen the connection between the connecting frame 170 and the support connection columns 100.

[0052] Reference Figure 2 In some specific embodiments of the present utility model, an auxiliary frame 220 can be provided between two groups of the support connection columns 100. The auxiliary frame 220 is threadedly screwed to the workbench through fastening screws. At least two lifting blocks 210 are slidably provided on both auxiliary frames 220, and the lifting blocks 210 are used for the rotational limit of the tensioning adjustment roller 200.

[0053] It is easily understandable that in this embodiment, by providing the auxiliary frame 220 and threadedly screwing the auxiliary frame 220 to the workbench through fastening screws, it is convenient for the staff to disassemble the auxiliary frame 220 and adjust the position of the auxiliary station. At the same time, the lifting blocks 210 slidably provided inside the auxiliary frame 220 can adjust the height of the tensioning adjustment roller 200 and the gap between the two, thereby changing the pressure exerted by the tensioning adjustment roller 200 on the material roller and then changing the tensioning force.

[0054] In some specific embodiments of the present utility model, a top plate can be threadedly screwed to the upper end of one side of the auxiliary frame 220 through a bolt. A threaded adjustment rod 230 is threadedly screwed to the middle of the top plate, and the threaded adjustment rod 230 is used for adjusting the height of the lifting block 210;

[0055] The threaded adjustment rod 230 passes through the two lifting blocks 210 and extends to the bottom of the auxiliary frame 220, and one end of the threaded adjustment rod 230 abuts against the bottom of the auxiliary frame 220.

[0056] It is easy to understand that in this embodiment, by providing a top plate, a threaded adjusting rod 230 is threadedly engaged in the middle of the top plate, and the threaded adjusting rod 230 is also threadedly engaged with the two lifting blocks 210. Thus, the staff can rotate the threaded adjusting rod 230 to adjust the height of the lifting blocks 210.

[0057] Secondly, when the height adjustment of one of the lifting blocks 210 is not required, the staff can manually apply pressure to it, so that it will no longer slide and adjust inside the auxiliary frame 220 under the action of the threaded adjusting rod 230.

[0058] In some specific embodiments of the present utility model, a plurality of adjusting blocks 110 can be slidably arranged inside each support connection column 100, the conveying roller 120 is rotatably arranged between every two adjusting blocks 110, the adjusting blocks 110 are connected to the support connection column 100 through limit bolts, and one end of the limit bolt abuts against the surface of the support connection column 100.

[0059] It is easy to understand that in this embodiment, by manually adjusting the height of the adjusting blocks 110, the gap between each conveying roller 120 is changed. Therefore, different material films can be conveyed by the conveying rollers 120. At the same time, limit bolts can be installed on the adjusting blocks 110 so that one end thereof can abut against the surface of the support connection column 100. Furthermore, the position of the adjusting blocks 110 can be fixed, and limit bolts are arranged on both sides of the adjusting blocks 110 to improve the connection limit between the adjusting blocks 110 and the support connection column 100.

[0060] In some specific embodiments of the present utility model, a top cover 150 can be threadedly engaged with the upper end of each support connection column 100 through a connection bolt, a pressure gauge 130 is fixedly arranged on the top cover 150, one end of the pressure gauge 130 penetrates through the top cover 150 and extends to the inside of the support connection column 100, and the pressure gauge 130 is used to detect the force and gap of the roller clamping the material.

[0061] It is easy to understand that in this embodiment, by providing the top cover 150, and the top cover 150 is threadedly engaged with the upper end of the support connection column 100 through a connection bolt. After the top cover 150 is connected to the support connection column 100, the adjusting block 110 located at the uppermost part inside the support connection column 100 can be detected by using the pressure gauge 130 provided in the middle thereof. Thus, the staff can know the gap between the two uppermost conveying rollers 120 through the numerical display of the pressure gauge 130, and thereby judge the clamping force between the two conveying rollers 120 on the material.

[0062] In some specific embodiments of the present utility model, a plurality of arc internal threaded grooves 140 may be provided on both corresponding sides of each support connection column 100, and the arc internal threaded grooves 140 are used for threaded connection of the device.

[0063] It is easily understandable that in this embodiment, by providing the arc internal threaded grooves 140 on both sides of the support connection column 100, the staff can install different devices on the support connection column 100 through the arc internal threaded grooves 140, and can use the rollers on different devices to change the use effect brought by the originally provided rollers.

[0064] In the description of this specification, the description with reference to terms such as "one embodiment, some embodiments, illustrative embodiments, examples, specific examples or some examples" means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of the present utility model.
