[0003] After retrieving the patent document with the publication number of CN219563265U, this patent document discloses "a cutting and segmenting device for double-sided tape processing. Through the setting of the transverse movement driving component and the segmenting cutting component, this device can control the second motor to drive the screw to rotate. Under the cooperation of the third screw hole and the screw, the mounting frame is driven to move transversely along the guide groove. Through the connecting frame, the cutting tool disc is driven to move transversely on the double-sided tape, realizing the segmenting cutting of the double-sided tape on the workbench. During the segmenting cutting process, the second bolt can be loosened to enable the collar to move transversely along the guide rod. During the transverse movement adjustment process, the cutting tool disc is driven to move transversely on the mounting shaft through the n-shaped frame, realizing the adjustment of the distance between the two cutting tool discs, thereby realizing the adjustment of the segmenting cutting width of the double-sided tape, and can conveniently cut double-sided tapes with different widths, improving the efficiency of segmenting cutting of the double-sided tape.";

[0004] When the above device is operating, although the distance between multiple cutting tools can be adjusted as needed through the transverse movement driving component in the above device, when adjusting the above device, the positions of multiple collars in the above device need to be adjusted and fixed, which will take a lot of time during the adjustment, resulting in a long time-consuming for the preliminary preparation work of the above device. Summary of the Invention

[0005] The purpose of the utility model is to provide a cutting device for double-sided tape processing to solve the above problems.

[0006] The utility model realizes the above purpose through the following technical solutions:

[0007] A cutting device for double-sided tape processing, including an operating table, an auxiliary mechanism is installed at the upper end of the operating table, and a cutting mechanism is also included;

[0008] The cutting mechanism includes a gantry, which is fixed to the upper end of the operating table. A rotating shaft is rotatably connected in the middle of the gantry. The input end of the rotating shaft is equipped with a motor. A limiting frame is fixed on the periphery of the rotating shaft. Four collar rings are slidably connected to the periphery of the limiting frame. A blade is fixed to the outer ring of each collar ring. Extension rings are fixed to the corresponding ends of the middle two collar rings. A spring is fixed between the two extension rings. The corresponding ends of the two collar rings in the corresponding positions are rotatably connected with swivel rings. A connecting rod is hinged to the upper end of each swivel ring. An electric push rod is installed at the upper end of the gantry. The telescopic end of the electric push rod is fixed with a lifting plate. Two sliders are slidably connected to the lower end of the lifting plate. The upper ends of the corresponding two connecting rods are hinged to one of the sliders. Lower extension plates are fixed to the lower ends on both sides of the lifting plate.

[0009] Preferably: The included angle between the corresponding two connecting rods is set at 90 degrees, and the lower end face of the lifting plate is higher than the upper end of the blade.

[0010] Preferably: The outer diameter of the extension ring is smaller than the outer diameter of the blade.

[0011] Preferably: The lower half section of the lower extension plate is of a triangular structure, and the two ends of the two lower extension plates are attached to the corresponding end faces of the two extension rings near the outer circle.

[0012] Preferably: The auxiliary mechanism includes four vertical plates, which are respectively fixed at the four corners of the upper end of the operating table. Guide rollers are rotatably connected between the corresponding two vertical plates. The blade is located at the middle position between the two guide rollers.

[0013] Preferably: The uppermost end of the guide roller is higher than the lowermost end of the blade.

[0014] The beneficial effects compared with the prior art are as follows:

[0015] Before the device operates, the device is adjusted first. Due to the sliding connection between the collar ring and the limiting frame, and the connecting rod is hinged to both the lifting plate and the corresponding swivel ring. When the electric push rod drives the lifting plate to descend, the distance between the corresponding two collar rings can be increased. While the electric push rod drives the lifting plate to descend, the lower extension plate can also descend accordingly. At this time, the two ends of the lower extension plate are respectively attached to the corresponding end faces of the two extension rings. Coupled with the sliding connection between the two sliders and the lifting plate, when the lower extension plate descends, the triangular structure in its lower half section will push the two extension rings to move, so that the distance between the middle two collar rings will also increase accordingly. In this way, when adjusting the device, only the electric push rod needs to be started for lifting and lowering to adjust the cutting position of each blade, thus reducing the time required for the pre-preparation work of the device.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0025] The following further illustrates the present invention with reference to the attached drawings:

[0026] As Figures 1 - 5 shown, a cutting device for double-sided tape processing includes an operating table 1, an auxiliary mechanism is installed at the upper end of the operating table 1, and a cutting mechanism is further included.

[0027] The auxiliary mechanism includes four vertical plates 2 which are respectively fixed at the four corners of the upper end of the operating table 1. Guide rollers 21 are rotatably connected between every two corresponding vertical plates 2. During operation, when the double-sided tape passes through the upper ends of the two guide rollers 21, the two guide rollers 21 can raise the double-sided tape.

[0028] The cutting mechanism includes a portal frame 3 which is fixed at the upper end of the operating table 1. A rotating shaft 31 is rotatably connected in the middle of the portal frame 3. The input end of the rotating shaft 31 is equipped with a motor 32. A limiting frame 33 is fixed on the periphery of the rotating shaft 31. Four collar rings 34 are slidably connected to the periphery of the limiting frame 33. A blade 35 is fixed to the outer ring of each collar ring 34. The four blades 35 are located at the middle position between the two guide rollers 21. The uppermost end of the guide roller 21 is higher than the lowermost end of the blade 35. Extension rings 36 are fixed to the corresponding ends of the middle two collar rings 34. The outer diameter of the outer ring of the extension ring 36 is smaller than the outer diameter of the blade 35. A spring 37 is fixed between the two extension rings 36. Rotating rings 38 are rotatably connected to the corresponding ends of the two collar rings 34 at the same position. A connecting rod 39 is hinged to the upper end of each rotating ring 38. An electric push rod 310 is installed at the upper end of the portal frame 3. The telescopic end of the electric push rod 310 is fixed with a lifting plate 311. The lower end surface of the lifting plate 311 is higher than the upper end of the blade 35. Two sliding blocks 313 are slidably connected to the lower end of the lifting plate 311. The upper ends of the two corresponding connecting rods 39 are hinged to one of the sliding blocks 313. The included angle between the two corresponding connecting rods 39 is set to 90 degrees. Lower extension plates 312 are fixed to the lower ends on both sides of the lifting plate 311. The lower half of the lower extension plate 312 is of a triangular structure, and the two ends of the two lower extension plates 312 are in contact with the corresponding end faces of the two extension rings 36 close to the outer ring; through the sliding connection between the collar ring 34 and the limiting frame 33 and the fact that the connecting rod 39 is hinged to both the lifting plate 311 and the corresponding rotating ring 38, when the electric push rod 310 drives the lifting plate 311 to descend, the distance between the two corresponding collar rings 34 can be increased. While the electric push rod 310 drives the lifting plate 311 to descend, the lower extension plate 312 can descend accordingly. At this time, through the two ends of the lower extension plate 312 being in contact with the corresponding end faces of the two extension rings 36 respectively, and combined with the sliding connection between the two sliding blocks 313 and the lifting plate 311, after the lower extension plate 312 descends, the triangular structure of its lower half will push the two extension rings 36 to move, so that the distance between the middle two collar rings 34 will increase accordingly. In this way, when adjusting the device, only the electric push rod 310 needs to be started to lift and lower to adjust the cutting position of each blade 35, thus reducing the time required for the pre-preparation work of the device.

[0029] Working principle: Before the device operates, first, through the sliding connection between the collar 34 and the limit frame 33, and the connecting rod 39 is hinged to both the lifting plate 311 and the corresponding rotating ring 38. When the electric push rod 310 is started to drive the lifting plate 311 to descend, the distance between the corresponding two collars 34 can be increased. At the same time when the electric push rod 310 drives the lifting plate 311 to descend, the lower extension plate 312 can descend accordingly. At this time, the two ends of the lower extension plate 312 are respectively attached to the corresponding end faces of the two outer extension rings 36. With the sliding connection between the two sliders 313 and the lifting plate 311, after the lower extension plate 312 descends, the triangular structure in its lower half will push the two outer extension rings 36 to move, so that the distance between the two collars 34 located in the middle will increase accordingly. On the contrary, when the electric push rod 310 drives the lifting plate 311 to ascend, the distance between the corresponding two collars 34 can be decreased. At the same time, through the elasticity of the spring 37, when the lower extension plate 312 ascends, the distance between the two collars 34 in the middle can be decreased accordingly. In this way, when it is necessary to adjust the width of the double-sided tape after cutting, only the electric push rod 310 needs to be controlled to ascend and descend to adjust the cutting position of each blade 35, thus reducing the time required for the preliminary preparation work of the device.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
