Specifically, the first roller 11 and the extrusion roller 12 are both cylindrical structures, and a push cylinder is fixedly installed on the top surface of the support frame 10, and a side plate is fixedly installed on the output shaft of the push cylinder. The extrusion roller 12 is installed on one side of the side plate. The extrusion roller 12 is pushed up and down by the push cylinder to adjust the distance between the extrusion roller 12 and the first roller 11 to adapt to larger indentation operations of different thicknesses. The push cylinder is a mature existing technology, and the push cylinder can be a servo electric cylinder. Of course, the push cylinder needs to be connected to the controller, and the models and specifications of the controller and the push cylinder are not too restricted here.

[0026] like Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the molding component can be detachably arranged on the wall surface of the extrusion roller 12, and the molding component includes a molding plate 20, a limiting sleeve 21, an anti-slip rod 23 and an installation channel 30. Two installation channels 30 are symmetrically opened on the wall surface of the extrusion roller 12, and two molding plates 20 are arranged on the wall surface of the extrusion roller 12. The molding plates 20 have a concave surface and a convex surface. The convex surface of the molding plates 20 is provided with an integrally formed protrusion. The concave surface of each molding plate 20 is fixedly connected to the anti-slip rod 23, and the anti-slip rod 23 is inserted into the corresponding installation channel 30. The limiting sleeve 21 is threadedly connected to the extrusion roller 12 and can fix the anti-slip rod 23 to the installation channel 30.

[0027] like Figure 5 As shown, the molding assembly also includes an extension body 24, which is fixedly connected to the anti-slip rod 23. Specifically, the anti-slip rod 23 and the anti-slip rod 23 are integrally formed, and the extension body 24 forms a bent rod body extending axially along the extrusion roller 12. The limiting sleeve 21 presses the bent rod body of the extension body 24.

[0028] like Figure 3 As shown, one end of the extrusion roller 12 is fixedly connected to the mounting section 13, the wall surface of the mounting section 13 is provided with threads, the limiting sleeve 21 is annular, the inner circumferential surface of the limiting sleeve 21 is provided with threaded teeth, the limiting sleeve 21 is threadedly connected to the mounting section 13, and the mounting section 13 is provided and the limiting sleeve 21 is limited by the mounting section 13, so that the limiting sleeve 21 can be rotated close to the end face of the extrusion roller 12, so that the position of the limiting sleeve 21 can be adjusted to facilitate locking of the forming plate 20.

[0029] Specifically, the limiting sleeve 21 includes two circular rings, which are integrally formed. The inner wall of one of the circular rings is provided with threaded teeth, and the inner wall of the other circular ring presses the bent rod body of the extension body 24. The forming plate 20 forms an arc plate structure. The forming plate 20 is equal in length to the extrusion roller 12. The anti-slip rod 23 is fixedly connected to the inner circumferential surface of the forming plate 20. The anti-slip rod 23 is adapted to the installation channel 30. A protrusion is provided on the outer circumferential surface of the forming plate 20. The two forming plates 20 together form a circular tube adapted to the extrusion roller 12.

[0030] like Figure 3 As shown, the other end of the extrusion roller 12 is fixedly connected with a boss 14, and the boss 14 forms an annular structure. The outer diameter of the boss 14 is larger than the diameter of the extrusion roller 12, and one end face of the boss 14 abuts against one end of the forming plate 20. The forming plate 20 is pushed on one side of the extrusion roller 12 by a limiting sleeve 21 to cooperate with the boss 14 on the other end face, so that the forming plate 20 can be better limited.

After the forming plate 20 and the extrusion roller 12 are installed, the stability is higher. When the extrusion roller 12 and the first roller 11 extrude the tape, the forming plate 20 will not slip or skid, thereby ensuring the smooth implementation of the indentation operation.

[0032] The working principle of the utility model is as follows: by rotating the limiting sleeve 21, the limiting sleeve 21 is separated from the extension body 24, the two forming plates 20 are removed from the surface of the squeezing roller 12, and the forming plates 20 with the required convex shape are replaced, the anti-slip rod 23 is pushed into the installation channel 30, and the installation channel 30 is used to limit the anti-slip rod 23 to inhibit the forming plate 20 from slipping relative to the squeezing roller 12, and the thrust block 22 is inserted into the insertion hole 25, so as to realize the radial and circumferential direction of the forming plate 20.
