Without the slitting equipment, it is impossible to effectively slit the light-shielding tapes to achieve the slitting effect. Therefore, the slitting equipment is a very important component. However, with the increasing demand for light-shielding tapes and the need to adapt to screens of different shapes and sizes, most traditional slitting equipment can only cut fixed sizes. When encountering different sizes, different slitting equipment needs to be replaced or the sizes need to be reset again, which is very inconvenient. Summary of the Utility Model

[0025] To further elaborate on the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the following, in conjunction with the attached drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present utility model as follows.

[0026] Please refer to Figures 1 - 7 As shown, the purpose of this embodiment is to provide a double-sided tape slitting mechanism, including a base 1. One side of the upper end of the outer surface of the base 1 is fixedly connected with a column 2. The upper end of the outer surface of the column 2 is sleeved with an upper bracket 3. The lower surface of the upper bracket 3 is fixedly connected with a cutting component 4. On the other side of the upper surface of the base 1, a fixing component 5 is fixedly arranged; a tape reel is placed on the fixing component 5;

[0027] A vertical adjustment part is provided between the base 1 and the column 2; the vertical adjustment part includes a driving source, and the driving source drives the column 2 and the cutting component 4 to move up and down, changing the position where the cutting component 4 stays on the surface of the tape reel, and adjusting the width of the tape to be slit;

[0028] The base 1 adopts an L-shaped structure with the left side higher than the right side. A square groove 11 is opened at one end of the base 1. The driving source is a hydraulic cylinder 12 fixedly installed in the square groove 11. Above the piston rod 13 of the hydraulic cylinder 12, a chassis 14 is fixedly connected. The upper end of the chassis 14 is fixedly connected with the lower end of the column 2. The hydraulic cylinder 12 makes the piston rod 13 move, driving the chassis 14, the column 2, the upper bracket 3 and the cutting component 4 to move up and down synchronously;

[0029] The cutting component 4 includes at least two limit blocks 41, and the upper ends of the limit blocks 41 are fixedly arranged at the lower end of the upper bracket 3.

[0030] A lead screw 42 is provided between the limit blocks 41. Both ends of the lead screw 42 are rotatably installed in the limit blocks 41. A lead screw motor is fixedly installed in the limit blocks 41. A slider 43 is threadedly installed on the lead screw 42. The limit blocks 41 are used to limit the sliding of the slider 43 within the lead screw 42, and the lead screw motor is used to drive the rotation of the lead screw 42.

[0031] It should be noted that the top of the slider 43 is in sliding contact with the surface of the upper bracket 3, so that the slider 43 can only move horizontally under the drive of the lead screw 42 and will not rotate;

[0032] A cutting motor is fixedly installed in the slider 43. The cutting motor is coaxially connected to a rotating shaft 44. The rotating shaft 44 is coaxially connected to a cutting blade 45. The cutting motor drives the rotation of the rotating shaft 44, and then drives the cutting blade 45 to rotate, so that the cutting blade 45 cuts the double-sided tape 56.

[0033] The fixing assembly 5 includes at least two support columns 53. A groove is formed in the support column 53, and a spring 54 is fixedly connected in the groove. The other end of the base 1 is fixedly installed with a transmission motor. The transmission motor is coaxially connected to a transmission shaft 51. A fixed base 52 is coaxially connected to the transmission shaft 51. The support column 53 is fixedly installed on the transmission shaft 51. The other end of the spring 54 is fixedly installed with a connecting rod 55. One end of the connecting rod 55 is fixedly installed with an arc-shaped support 551. After the tape reel is placed on the fixed base 52, the connecting rod 55 is released, and the elastic force of the spring 54 is used to squeeze the connecting rod 55 and the arc-shaped support 551, so that they tightly abut against the inner wall of the tape reel to fix the tape reel. A number of fine particles for increasing friction are provided on the surface of the arc-shaped support 551, which can increase the stability when squeezing and fixing the tape reel.

[0034] A limiting member 531 is rotatably installed at the upper end of the support column 53. A limiting column 552 is fixedly installed at the upper end of the connecting rod 55. A limiting groove is formed on the side surface of the limiting member 531. After squeezing the spring 54, the limiting member 531 is rotated so that the limiting column 552 is caught in the groove of the limiting member 531 to fix the connecting rod 55, which is convenient for placing the double-sided tape 56.

[0035] When the utility model is specifically used, the limiting block 41 restricts the front and rear sliding range of the slider 43 on the lead screw 42. The lead screw motor drives the lead screw 42 to rotate, and the output shaft of the cutting motor in the slider 43 rotates, driving the rotating shaft 44 to rotate, and then driving the cutting blade 45 to rotate. Before that, the compression spring 54 is compressed, so that the connecting rod 55 and the limiting column 552 thereon move backward. The limiting member 531 is rotated, so that the limiting column 552 is caught in the groove of the limiting member 531 to limit the connecting rod 55. At this time, the distance between the two arc-shaped supports 551 is smaller than the inner diameter of the tape cylinder. Then, the tape cylinder is placed on the fixed base 52, and the limiting member 531 is rotated, so that the limiting column 552 is disengaged from the limiting member 531. Under the elastic force of the spring 54, the connecting rod 55 and the arc-shaped support 551 are pressed, so that they tightly abut against the inner wall of the tape cylinder to fix the tape cylinder. The cutting blade 45 is driven to move by the action of the lead screw 42 and the slider 43, so that it contacts the double-sided tape on the surface of the tape cylinder, and the double-sided tape is cut under the rotation of the cutting blade 45;

[0036] The piston rod 13 is driven to expand and contract up and down by the hydraulic cylinder 12, driving the chassis 14 to move up and down, and then driving the column 2 and the upper bracket 3 to move up and down, so as to drive the entire cutting assembly 4 to move up and down. In this way, the position where the cutting blade 45 stays on the surface of the tape cylinder can be realized, and thus the width to be cut each time can be changed as needed.

[0037] To further elaborate on the technical means and effects adopted by the utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, detail the specific implementation manner, structure, features and their effects of the utility model as follows.

[0038] The above is only a preferred embodiment of the utility model, and it does not impose any form of limitation on the utility model. Although the utility model has been disclosed above with the preferred embodiment, it is not intended to limit the utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to make equivalent embodiments with equivalent changes within the scope of the technical solution of the utility model. However, as long as it does not depart from the content of the technical solution of the utility model, any brief modification, equivalent change and modification made to the above embodiments based on the technical essence of the utility model still fall within the scope of the technical solution of the utility model.
