[0026] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is described in detail below in conjunction with the accompanying drawings. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present application.

[0027] Please refer to Figure 1 -2. This embodiment provides a supporting and pressing device for a paper roll, including a base body 100, on which a pressure roller 200 and a winding roller 300 are mounted in parallel; the pressure roller 200 is connected to the base body 100 via a mounting frame 210, and is rotatably connected to the mounting frame 210, so as to press the base paper 310 onto the winding roller 300 without restricting the relative displacement of the base paper 310; the mounting frame 210 is rotatably mounted on the base body 100, and is driven by a cylinder 110, so as to drive the pressure roller 200 to press the winding roller 300 at a constant pressure.

[0028] In this embodiment, the pressure roller 200 is connected to the base 100 through the mounting frame 210 and is parallel to the winding roller 300; at the same time, the mounting frame 210 and the base 100 can also rotate relative to each other, so that the pressure roller 200 can always be against the winding roller 300, thereby ensuring the tightness of the winding roller 300 on the base paper 310.

[0029] In this embodiment, the pressing roller 200 is rotatably mounted on the mounting frame 210 , and after abutting against the winding roller 300 , it can not only press the base paper 310 against the winding roller 300 , but also move relative to the base paper 310 through rotation.

[0030] In this embodiment, a cylinder 110 is further installed between the mounting frame 210 and the base body 100; when the cylinder 110 is fully extended, the pressure roller 200 and the winding roller 300 are against each other. As the base paper 310 on the winding roller 300 increases, the diameter becomes larger, and the pressure between the pressure roller 200 becomes larger and is relatively greater than the supporting force of the cylinder 110. Therefore, the cylinder 110 will shrink accordingly to ensure that the pressure roller 200 can continuously wind up the base paper 310.

[0031] In a preferred embodiment, parallel mounting rods 211 are provided on the mounting frame 210 at both ends corresponding to the pressure roller 200; the pressure roller 200 is vertically and rotatably mounted at one end of the mounting rod 211; the end of the mounting rod 211 away from the pressure roller 200 is rotatably mounted on the base 100, and the rotation axis is parallel to the rotation axis of the pressure roller 200.

[0032] In this embodiment, the mounting frame 210 includes mounting rods 211 located at both ends of the pressure roller 200; one end of the mounting rod 211 is connected to the pressure roller 200, and the other end is connected to the base 100; the pressure roller 200 and the mounting rod 211 are rotatably connected, and the base 100 is hinged to the mounting rod 211.

[0033] In this embodiment, the rotation axis between the mounting rod 211 and the pressure roller 200 is parallel to the rotation axis between the mounting rod 211 and the base 100 , so that the pressure roller 200 can both rotate and adjust the distance relative to the winding roller 300 .

[0034] In a preferred embodiment, a connecting rod 212 is further provided between the two mounting rods 211 ; the number of the connecting rods 212 is not less than two, the multiple connecting rods 212 are parallel to each other, and both ends are fixedly mounted on the mounting rods 211 respectively, for linking the two mounting rods 211 .

[0035] In this embodiment, two parallel connecting rods 212 are connected in the middle of the two mounting rods 211; the ends of the connecting rods 212 are fixedly connected to the mounting rods 211, so that the two mounting rods 211 rotate synchronously, thereby ensuring that the axial angle of the pressure roller 200 remains unchanged during the rotation.

[0036] In a preferred embodiment, the cylinder 110 is respectively located on both sides of the mounting frame 210 and is installed between the base 100 and the mounting rod 211; a mounting seat is provided on the base 100 corresponding to the cylinder body of the cylinder 110, which is used to be hinged with the cylinder 110; a hinge seat is provided on the mounting rod 211 corresponding to the cylinder rod of the cylinder 110, which is used to be hinged with the cylinder 110.

[0037] In this embodiment, the cylinder 110 is installed between the mounting rod 211 and the base 100, and the pressure roller 200 can be pressed against the winding roller 300 by extending the cylinder rod; at the same time, as the diameter of the winding roller 300 increases, the cylinder rod of the cylinder 110 will also be forced to contract, so that the pressure of the pressure roller 200 on the winding roller 300 remains unchanged.

[0038] In a preferred embodiment, the pressing roller 200 includes a pressing roller body and a pressing roller sleeve coaxially sleeved on the pressing roller body; a spring is arranged between the pressing roller body and the pressing roller sleeve, and the pressing roller body is rotatably connected to the mounting rod 211. By coaxially sleeved the pressing roller sleeve outside the pressing roller body and arranging a spring between the pressing roller body and the pressing roller sleeve, the base paper can be more effectively pressed on the winding roller to ensure that the paper roll is tight and not loose.

[0039] Furthermore, the springs are arranged in an arrangement, for example, a plurality of spring units are arranged on the outer wall of the roller body along its axial direction, each spring unit includes a plurality of springs arranged along the circumferential direction, and both ends of the springs are respectively connected to the outer wall of the roller body and the inner wall of the roller sleeve.
