DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0026] In the embodiment, Figure 1 , Figure 2 , Figure 3 As shown, the front roller pressing mechanism includes a frame and a front roller 1 arranged in the frame, and also includes:

[0027] A telescopic element 2 is arranged in the frame;

[0028] A mounting block 3, used for connecting with the telescopic element 2;

[0029] Connecting rods 4 are arranged on both sides of the mounting block 3;

[0030] A pressing plate 5 is arranged at one end of the connecting rod 4 away from the mounting block 3, and the pressing plate 5 is provided with a slot 6 for cooperating with the front roller 1;

[0031] The connecting plate 7 is arranged on the frame, and the pressing plate 5 is circumferentially matched with the connecting plate 7 .

[0032] The connecting rod 4 is driven up by the telescopic element 2, and the pressure plate 5 is swung downward by a certain angle through the connecting plate 7, and the front roller 1 is pressed tightly through the slot 6. The telescopic element 2 is pneumatic or electric, and the front roller 1 is stably pressurized, and the problem of unstable pressurization due to long-term use will not occur.

[0033] In the embodiment, Figure 2 , Figure 4 As shown, both ends of the front roller 1 are provided with symmetrically arranged annular grooves 8, and the pressing plate 5 cooperates with the annular grooves 8, and the thickness of the pressing plate 5 is the same as the width of the annular grooves 8. After the pressing plate 5 cooperates with the front roller 1, it is ensured that the pressure on both ends of the front roller is the same, and at the same time, a certain limit effect is played on the pressing plate 5.

[0034] In the embodiment, Figure 1 , Figure 2 As shown, it also includes a mounting seat 9 that cooperates with the telescopic element 2, and connecting seats 10 are provided on both sides of the mounting seat 9. The mounting seat 9 and the connecting seat 10 are circumferentially matched, and the length of the connecting rod 4 is adjustable. After the front roller 1 is adjusted in position, the pressing plate 5 can be matched with the front roller 1 by swinging the telescopic element 2 to a certain angle and then adjusting the length of the connecting rod 4, without disassembling the telescopic element 2, and having good versatility.

[0035] In the embodiment, Figure 2 As shown, the connecting rod 4 includes a first threaded rod 41 and a second threaded rod 42, and the adjacent ends of the first threaded rod 41 and the second threaded rod 42 are both provided with an adjusting nut 43. The length of the connecting rod 4 can be adjusted by rotating the adjusting nut 43, and the adjustment is convenient.

[0036] In the embodiment, Figure 2 , Figure 3 As shown, the connecting plate 7 is provided with a limit block 11 for acting on the pressing plate 5. The pressing plate 5 is limited to prevent the pressing plate 5 from moving left and right on the front roller 1, ensuring that the pressure on both sides of the front roller 1 is the same.

[0037] In the embodiment, Figure 5As shown, the telescopic element 2 includes a telescopic rod passing through a mounting block 3, and the upper and lower ends of the mounting block 3 are provided with a locking nut 12 and a gasket 13 for mounting on the telescopic rod, and the mounting block 3 is provided with a groove 14, and one side of the gasket 13 is provided with a protrusion 15 for matching with the groove 14. The gasket 13 cooperates with the mounting block 3 to prevent loosening, and ensures that the telescopic element 2 drives the pressure plate 5 to act on the front roller 1 stably.

[0038] In the embodiment, the telescopic element 2 is a cylinder. The power output of the cylinder is stable, ensuring that the pressure of the pressure plate 5 on the front roller 1 is stable; of course, the telescopic element 2 can also be a hydraulic cylinder or an electric cylinder.
