The tensioning assembly 5 includes: a drive adjustment device 6 connected to the processing table assembly 2; and a linkage stretching assembly 7 connected to the processing table assembly 2, used in conjunction with the drive adjustment device 6 to complete the stretching adjustment of the film layer.

[0024] In one embodiment of the present invention:

[0025] like Figure 1 and Figure 2 As shown, the processing table assembly 2 includes: a plurality of supports 201 connected to the base 1; a processing table 202 connected to one end of the supports 201 away from the base 1; at least two grooves 203 disposed on the outer side of the processing table 202; a limiting rod 204 connected to the grooves 203; and a housing 205 connected to the processing table 202.

[0026] One side of the film layer to be processed is wound on the loading roller assembly 3, and the other side is tensioned and connected to the tensioning assembly 5 and the collecting roller assembly 4. According to the characteristics of the film layer, the film layer is stretched to different degrees by the drive adjustment device 6 and the linkage stretching assembly 7. Then, with the help of the heating assembly 8, the film layer is heated. The loading roller assembly 3 and the collecting roller assembly 4 on both sides rotate synchronously, which can drive the film layer to be continuously conveyed and complete the continuous heating of the film layer.

[0027] In one embodiment of the present invention:

[0028] like Figure 1 and Figure 2 As shown, the loading roller assembly 3 includes: a connecting frame 301, which is connected to the processing table 202; a first driving member 302, which is connected to the connecting frame 301; the first driving member 302 is an electric roller shaft; and a loading roller 303, which is fixedly connected to the first driving member 302.

[0029] Driven by the first driving component 302, the loading roller 303 can be driven to rotate synchronously, and in conjunction with the collecting roller assembly 4, the continuous conveying of the film layer is completed. The film layer is stretched by the tensioning component 5, heated by the heating component 8, and collected by the collecting roller assembly 4. It can also undergo secondary heating treatment through the collecting roller assembly 4 to prevent the film layer from cooling too quickly.

[0030] In this application, the first driving component 302 is not limited to an electric roller shaft. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can drive the rotation of the loading roller 303. No specific limitation is made here.

[0031] In one embodiment of the present invention:

[0032] like Figures 1 to 3 As shown, the collecting roller assembly 4 includes: at least two fixed frames 401 connected to the processing table 202; a limiting groove 402 disposed inside the fixed frame 401; a connecting shaft frame 403 slidably connected to the limiting groove 402; a second driving member 404 connected to the fixed frame 401; the second driving member 404 is an electric roller shaft; a sleeve roller 405 fixedly mounted outside the second driving member 404; a first elastic member 406 connected at one end to the fixed frame 401 and at the other end to the connecting shaft frame 403; the first elastic member 406 is an elastic telescopic rod; and a heating roller 407 connected to the connecting shaft frame 403 and abutting against the sleeve roller 405.

[0033] Driven by the second driving member 404, the sleeve roller 405 can be rotated, thereby completing the winding drive of the heated film layer. The heated film layer is collected outside the sleeve roller 405. At the same time, the heating roller 407 can rotate synchronously with the sleeve roller 405 to reheat the wound film layer and prevent the film layer from cooling too quickly. Meanwhile, as the thickness of the wound film layer increases, in conjunction with the first elastic member 406, the connecting shaft frame 403 can move horizontally along the limiting groove 402, and the heating roller 407 moves horizontally to adjust accordingly.

[0034] In this application, the second driving component 404 is not limited to an electric roller shaft. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the rotation adjustment of the sleeve roller 405. No specific limitation is made here.

[0035] In one embodiment of the present invention:

[0036] like Figure 1 and Figure 4As shown, the drive adjustment device 6 includes: a third drive component 601, which is connected to the processing table 202; the third drive component 601 is an electric roller; and an arc frame 602, which is fixedly connected to the third drive component 601 and abuts against the linkage tensioning assembly 7.

[0037] The arc frame 602 is elliptical in shape. When the third drive component 601 rotates, it can drive the arc frame 602 to rotate synchronously, and the two sides of the linkage tension component 7 can be adjusted synchronously, thereby changing the tension of the film layer.

[0038] In this application, the third driving component 601 is not limited to an electric roller shaft. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the rotation adjustment of the arc frame 602. No specific limitation is made here.

[0039] In one embodiment of the present invention:

[0040] like Figure 1 and Figure 2 As shown, the linkage tensioning assembly 7 includes: a sleeve 701, which is movably connected to the limiting rod 204; a second elastic element 702, which is sleeved outside the limiting rod 204, with one end fixedly connected to the groove 203 and the other end fixedly connected to the sleeve 701; the second elastic element 702 is a spring; a linkage frame 703, which is movably connected to the sleeve 701 at one end; a transmission frame 704, which is movably connected to the processing table 202, movably connected to the end of the linkage frame 703 away from the sleeve 701, and abuts against the arc frame 602; a fixed shaft frame 705, which is connected to the transmission frame 704; and a connecting sleeve roller 706, which is fitted and fixedly connected to the fixed shaft frame 705.

[0041] When the two arc-shaped frames 602 rotate, the sleeve 701 can move elastically along the limiting rod 204. In conjunction with the linkage frame 703, the transmission frame 704 and the connecting sleeve roller 706 can be rotated and adjusted, thereby adjusting the tension of the film layer that is in contact with the connecting sleeve roller 706.

[0042] In one embodiment of the present invention:

[0043] like Figure 1As shown, the heating assembly 8 includes: a fourth driving member 801, which abuts against the processing table 202; the fourth driving member 801 is an electric telescopic rod; a heating member 802, which is connected to the fourth driving member 801; the heating member 802 is an electric heating plate; at least two base frames 803, which are connected to the processing table 202; and a base plate 804, which is connected to the end of the base frame 803 away from the processing table 202.

[0044] When the fourth driving component 801 is running, it can drive the heating component 802 to move down. Through the cooperation of the heating component 802 and the base plate 804, the conveyed film layer can be heated.

[0045] In this application, the fourth driving component 801 is not limited to an electric telescopic rod. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the longitudinal movement adjustment of the heating component 802. No specific limitation is made here.

[0046] The working principle of this invention is as follows: One side of the film layer to be processed is wound onto the loading roller assembly 3, and the other side is tensioned and connected to the tensioning assembly 5 and the collecting roller assembly 4. According to the characteristics of the film layer, the film layer is stretched to different degrees through the cooperation of the drive adjustment device 6 and the linkage stretching assembly 7. Then, with the cooperation of the heating assembly 8, the film layer is heated. The loading roller assemblies 3 and the collecting roller assembly 4 on both sides rotate synchronously, which can drive the film layer to be continuously conveyed and continuously heated. Under the drive of the first drive member 302, the loading roller 303 can be driven to rotate synchronously, which, with the cooperation of the collecting roller assembly 4, completes the continuous conveying of the film layer. When the film layer is stretched by the tensioning assembly 5, heated by the heating assembly 8, and collected by the collecting roller assembly 4, it can also undergo secondary heating treatment through the collecting roller assembly 4 to prevent the film layer from cooling too quickly. The first drive member 302 is not limited to the electric roller shaft device. Alternatively, a linear motor, electric cylinder, or pneumatic cylinder can be used, as long as it can drive the rotation of the loading roller 303. No specific limitation is made here. Under the drive of the second drive member 404, the sleeve roller 405 can be driven to rotate, thereby completing the winding drive of the heated film layer. The heated film layer is collected outside the sleeve roller 405. At the same time, the heating roller 407 can rotate synchronously with the sleeve roller 405 to reheat the wound film layer and prevent the film layer from cooling too quickly. Meanwhile, as the thickness of the wound film layer increases, in conjunction with the first elastic member 406, the connecting shaft frame 403 can move horizontally along the limiting groove 402, and the heating roller 407 moves horizontally to adjust accordingly. The second drive member 404 is not limited to an electric roller shaft. A linear motor, electric cylinder, or pneumatic cylinder can also be used, as long as it can drive the rotation of the sleeve roller 405. No specific limitation is made here.

[0047] The arc-shaped frame 602 is elliptical in shape. When the third driving component 601 rotates, it drives the arc-shaped frame 602 to rotate synchronously, and the two-sided linkage tensioning components 7 are adjusted synchronously, thereby changing the tension of the film layer. The third driving component 601 is not limited to an electric roller shaft; it can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can achieve the rotation adjustment of the arc-shaped frame 602. No specific limitation is made here. When the two sides of the arc-shaped frame 602 rotate, the sleeve 701 can move elastically along the limiting rod 204, cooperating with the linkage. The frame 703, transmission frame 704, and connecting sleeve roller 706 are rotatable and adjustable, thereby adjusting the tension of the film layer that is in contact with the connecting sleeve roller 706. When the fourth driving component 801 is running, it can drive the heating component 802 to move downward. Through the cooperation of the heating component 802 and the base plate 804, the conveyed film layer can be heated. The fourth driving component 801 is not limited to an electric telescopic rod. It can also be driven by a linear motor, electric cylinder, or pneumatic cylinder, etc., as long as it can realize the longitudinal movement adjustment of the heating component 802. No specific limitation is made here.

[0048] In summary, this device, through the cooperation of the drive adjustment device and the linkage stretching assembly, can achieve different degrees of tension and stretching of the film layer. At the same time, the heating assembly, in conjunction with the material collection roller assembly, can complete dual heating, further improving the heating quality of the film material and overcoming the shortcomings of existing polarizing film heating equipment.
