[0024] In this embodiment, two feed guide rails 25 are symmetrically arranged and fixed with threaded bolts. Four movable sliders 23 are provided. The lower movable fixing plate 21 and the movable slider 23 are integrated. Eleven rotating shafts 29 are provided in the lower movable fixing plate 21 and eight rotating shafts 29 are provided in the upper movable fixing plate 5. The rotating shafts 29 are fixed by bearings in the lower movable fixing plate 21 and the upper movable fixing plate 5. The winding fixing shell 9 and the turntable fixing seat 10 are integrally formed. A bearing is provided between the turntable 11 and the turntable fixing seat 10. Two rotating rollers 14 are provided and fixed by welding.
[0025] Specifically, a grooved cutting plate 7 and a cutting station 15 are fixedly installed on the upper end face of the feeding station 1. Cutting guide grooves 28 are provided on the inner two end faces of the cutting station 15. A cylinder 6 is fixedly installed on the upper end face of the cutting station 15. A connecting rod 27 is fixedly connected to the lower part of the cylinder 6. A cutter 2 is fixedly connected to the lower end face of the connecting rod 27.
[0026] In this embodiment, the grooved cutting plate 7, the cutting fixed table 15 and the feeding fixed seat 1 are integrally formed. Three cylinders 6 are equally spaced. The connecting rod 27 passes through the cutting fixed table 15. By controlling the lifting and lowering of the cylinders 6, the cutter 2 moves up and down along the cutter guide groove 28.
[0027] Specifically, a connecting piece 24 is provided between the lower movable fixing plate 21 and the upper movable fixing plate 5, and the connecting piece 24 is fixedly installed on the outer end faces of both sides of the lower movable fixing plate 21.
[0028] In this embodiment, six connecting pieces 24 are symmetrically arranged on the left and right sides and are fixed to the lower movable fixing plate 21 by bolts. The upper half of the connecting piece 24 is a long slot, and the upper movable fixing plate 5 can be moved up and down by fixing bolts, thereby adjusting the distance between the upper rotating belt 3 and the lower rotating belt 4.
[0029] Specifically, a servo motor 20 is fixedly installed on the left end face of the upper movable fixed plate 5 and the lower movable fixed plate 21, and the rotating shaft of the servo motor 20 is fixedly connected to the left end face of the rotating shaft 29.
[0030] In this embodiment, four servo motors 20 are provided and fixed by servo motor mounting brackets.
[0031] Specifically, lifting guide rails 8 are fixedly installed on the front and rear end faces of the winding and fixing shell 9. A lifting slider 17 is provided on the end face of the lifting guide rail 8 away from the winding and fixing shell 9. An upper pressure plate fixing plate 19 and a lower pressure plate fixing plate 26 are fixedly installed on the inner end faces of both sides of the lifting slider 17. An upper pressure plate 12 is fixedly installed on the front end face of the upper pressure plate fixing plate 19, and a lower pressure plate 13 is fixedly installed on the front end face of the lower pressure plate fixing plate 26.
[0032] In this embodiment, two lifting guide rails 8 are symmetrically arranged. The movement of the lifting slider 17 drives the upper pressure plate fixing plate 19 and the lower pressure plate fixing plate 26, as well as the upper pressure plate 1212 and the lower pressure plate 13 to move.
[0033] Specifically, a rotating motor 18 is fixedly installed on the left end face inside the winding fixed shell 9, and a coupling 16 is fixedly connected to the right end of the rotating motor 18. The right end of the coupling 16 is fixedly connected to the rotating shaft of the turntable 11.
[0034] In this embodiment, the rotating motor 18 provides power for winding, and the kinetic energy is transmitted from the rotating motor 18 to the turntable 11 through the coupling 16. The rotation speed of the turntable 11 is slightly greater than the rotation speed of the upper rotating belt 3 and the lower rotating belt 4.
[0035] The working principle and usage process of this utility model are as follows: The operator adjusts the splice 24 to move the upper movable fixing plate 5 to a suitable position, then turns on the power, puts the papermaking blanket onto the lower rotating belt 4, and simultaneously controls the movement of the movable slider 23, thereby driving the upper movable fixing plate 5 and the lower movable fixing plate 21 to move forward. Under the operation of the servo motor 20, the rotating shaft 29 drives the upper rotating belt 34 and the lower rotating belt 4 to rotate, conveying the papermaking blanket forward. Under the operation of the rotating motor 18, the turntable 11 rotates, and the papermaking blanket is wound up by the rotating roller 14. As the winding radius increases, the upper pressure plate 12 and the lower pressure plate 13 begin to move away from each other, always applying a certain pressure. After reaching the maximum winding radius, the cylinder 6 starts to work, thereby driving the cutter 2 to cut the papermaking blanket and retract it. After the worker removes the packaged papermaking blanket, the next winding operation can be carried out.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
