The first left guide roller 42, the second left guide roller 43, the first right guide roller 44 and the second right guide roller 45 are inserted into the cavity of the bearing frame 41. The first left guide roller 42 and the second left guide roller 43 are both horizontally disposed, and are disposed side by side in the vertical direction, and are spaced apart from each other by a predetermined distance to form a left penetrating slit 46 for the perforated waste tape to pass through and to be horizontally disposed. The first right guide roller 44 and the second right guide roller 45 are vertically arranged, are arranged side by side along the front-rear direction, and are spaced from each other by a predetermined distance to form a right through slit 47 through which the perforated waste tape passes and is vertically arranged. In the process of receiving the waste material belt, the waste material belt is firstly twisted for the first time through the right penetrating seam 47 and then twisted for the second time through the left penetrating seam 46, and finally the deformation from the flat shape to the twist shape is finished. The slit width of the right through slit 47 is set according to the thickness value t of the pre-passing waste tape, and the slit width of the left through slit 46 is set according to the maximum diameter of the waste tape after one-time torsion forming, and generally the single-side gap is controlled between 1/10t-3/10 t.

The waste belt torsion unit 4 is arranged by adopting the technical scheme, and the following beneficial technical effects are mainly obtained: 1) the waste material belt is ensured to have better rapidness and smoothness in the torsional deformation process, and the clamping stagnation phenomenon is avoided; 2) the waste material belt twisting unit 4 does not need power transmission in the working process, and can realize the twisting of the appearance of the waste material belt only by means of the pulling force applied to the waste material belt; 3) the scrap belt twisting unit 4 is simple in structural design and easy to manufacture and implement.

As can also be seen from fig. 6, the front end and the rear end of the first left guide roller 42 are both fixed to the force bearing frame preferably by means of first screws; the front end and the rear end of the second left guide roller 43 are fixed with the bearing frame 41 preferably by means of second screws; the upper end and the lower end of the first right guide roller 44 are fixed with the bearing frame preferably by means of a third screw; the upper end and the lower end of the second right-positioned guide roller 45 are both fixed with the bearing frame 41 preferably by means of fourth screws. Correspondingly, as shown in fig. 7, a first left waist-shaped hole 411 for a first screw to pass through and extend along the up-down direction is formed on each of the front and rear side walls of the bearing frame 41; second left waist-shaped holes 412 which are used for a second screw to pass through and extend along the up-down direction are formed in the front side wall and the rear side wall of the bearing frame 41; the upper and lower side walls of the bearing frame 41 are both provided with a first right waist-shaped hole 413 which is used for a third screw to pass through and extends along the front-back direction; the upper and lower side walls of the bearing frame 41 are both provided with second right waist-shaped holes 414 for the fourth screws to pass through and extend along the front-back direction. Therefore, when the thickness or the width of the pre-wound scrap belt is changed, the slit widths of the left through slit 46 and the right through slit 47 can be conveniently and quickly adjusted. The specific operation steps are as follows: as shown in fig. 6, when the width of the left penetrating slit 46 needs to be adjusted, first and second screws need to be loosened, the first and second left guide rollers 42 and 43 are dragged along the up-down direction until the width of the slit meets the design requirement, and then the first and second screws are locked in real time; when the width of the right penetrating slit 47 needs to be adjusted, the third screw and the fourth screw need to be loosened, the first right guide roller 44 and the second right guide roller 45 are dragged along the front-back direction until the width of the slit meets the design requirement, and the third screw and the fourth screw are locked immediately.

It should be emphasized that the material receiving device for the perforated waste tape may be additionally provided with a gravity tensioning unit 6 according to actual conditions on site or customer requirements. The gravity tensioning unit 6 is supported by the front side wall of the cabinet 1 and arranged right below the first material supporting roller 51 and the second material supporting roller 52 to always tension the perforated waste belt. As shown in fig. 8, the gravity tensioning unit 6 includes an upper mount 61, a lower mount 62, a guide rod assembly 63, a counterweight sliding block 64, and a tensioning material roller 65. The upper mounting seat 61 and the lower mounting seat 62 are detachably fixed on the front side wall of the cabinet 1 and are opposite to each other to jointly fix the guide rod assembly 63. Tensioning material roller 65 always pulls the perforated waste tape and assembles as an organic whole with counterweight sliding block 64.

A linear driving unit 7 is fixed to a front side wall of the cabinet 1 to drag the scrap belt twisting unit to perform a reciprocating displacement motion in a front-rear direction (as shown in fig. 1). In this way, during the actual winding process of the waste tape, the linear driving unit 7 drags the waste tape twisting unit 4 to perform a reciprocating linear motion, so that the twisted waste tapes are sequentially arranged along the axial direction of the material receiving tray 22, thereby increasing the receiving amount thereof. It should be noted that, during the winding process, the linear displacement speed of the linear driving unit 7 needs to be strictly controlled to ensure the arrangement compactness of the waste tape on the receiving tray 22.

Finally, it should be noted that the linear drive unit 7 can assume a variety of designs in order to achieve the reciprocating drive of the scrap belt twisting unit 4, however, a preferred embodiment is proposed here, in particular as follows: as shown in fig. 9, the linear driving unit 7 includes a support base 71 and a ball screw linear module 72.
