[0002] In the tape industry, due to different usage conditions, the width of each roll of tape is also different, so tape slitting equipment is needed to slit the tape. During slitting, the wide roll of tape masterbatch is cut into tapes of the required width and rewound into small rolls at the same time. In this process, the tension of the tape rewound into small rolls needs to be controlled, but the existing slitting equipment can only control the tension of all the tapes rewound into small rolls at the same time, and cannot control them individually. When there is a problem with the rewinding of one of the small rolls of tape, it will affect the tension control of other rolls of tape. Utility Model Content

[0022] like Figure 1-5 As shown in the figure, the tension control device of the tape slitting equipment is described in detail:

[0023] A tension control device for tape slitting equipment comprises a transverse plate 1, an arm plate 2, a square shaft 3, a round seat 7, a through long hole 8, an outer ring 9 and a spring 11; the long holes arranged at both ends of the transverse plate 1 are used for passing bolts to install and fix the slitting equipment, and the arrangement of the long holes facilitates the adjustment of the installation position of the transverse plate 1, the two arm plates 2 are vertically fixed on the transverse plate 1 for installing the square shaft 3, the middle parts of the plurality of round seats 7 are provided with through long holes 8, the through long holes 8 can cooperate and slide on the square shaft 3, each round seat 7 is rotatably provided with an outer ring 9, the through long hole 8 is fixed with a spring 11, and the other end of the spring 11 presses against the square shaft 3.

[0024] When in use, the outer ring 9 presses against the back side of the cut small tape, and the tension of the small tape is controlled by the elastic force of the spring 11. Since multiple outer rings 9 press against multiple different small tapes respectively, when there is a problem in the rewinding of one of the small tapes, it will only affect the outer ring 9 in contact with it, while the tension of other small tapes will not be affected, thereby ensuring the rewinding quality of other small tapes.

[0025] Further:

[0026] By providing a rubber layer on the outer end face of the outer ring 9, the small tape can be protected when the outer ring 9 is pressed against the back side of the small tape to avoid damage to the tape. At the same time, by providing edges at both ends of the rubber layer, blocks are formed on both sides of the small tape to avoid separation of the rubber layer and the small tape during rolling, thereby affecting the tension control of the small tape.

[0027] like Figure 1-5 As shown:

[0028] Each through-hole 8 is threadedly connected with a tightening screw 10 at the end away from the spring 11, and the tightening screw 10 tightens the square shaft 3. The tightening screw 10 is provided with a circular tightening block near the end of the square shaft 3.

[0029] The circular tightening block is driven to rotate the tightening screw 10, so that the tightening screw 10 and the round seat 7 are threadedly transmitted, so that the tightening screw 10 drives the circular tightening block to move axially, so that the circular tightening block can tighten the square shaft 3, so that the round seat 7 slides on the square shaft 3 through the long hole 8, thereby adjusting the relative position of the round seat 7 and the square shaft 3, thereby adjusting the initial position of the outer ring 9 on the round seat 7, so that each outer ring 9 can present different tension control.

[0030] like Figure 1-5 As shown:

[0031] The square shaft 3 is provided with a plurality of circular grooves 5 near the spring 11 for limiting the position of the spring 11. Circular plates 12 are fixed at both ends of the spring 11, one of which slides in the corresponding circular groove 5 and the other is inserted into the groove on the through-long hole 8.

[0032] The circular plates 12 fixed at both ends of the spring 11 cooperate with the circular groove 5 and the groove respectively, thereby ensuring that the spring 11 can limit the relative position of the square shaft 3 and the round seat 7, avoiding axial sliding of the round seat 7 on the square shaft 3. At the same time, the spring 11 can be easily replaced to ensure tension control of springs 11 with different elastic forces.

[0033] like Figure 1-5 As shown:

[0034] Both ends of the square shaft 3 are matched and connected with round sleeves 4, and the two round sleeves 4 are respectively damped and rotated on the two arm plates 2. A worm 6 is rotated on one of the arm plates 2, and the worm 6 is meshed and driven with the worm wheel on the round sleeve 4 on the corresponding side.

[0035] By rotating the worm 6, the meshing transmission worm wheel can drive the round sleeve 4 to rotate, thereby driving the square shaft 3 to rotate, so as to adjust the sliding direction of the round seat 7 on the square shaft 3, thereby forming a control of the tension direction, thereby improving the adaptability of the installation position of the cross plate 1 on the slitting equipment.
