Description

Technical Field

[0002] In order to reduce the replacement time of the blades of the asynchronous jump cutting device, a Chinese patent document with publication number CN215790128U discloses an asynchronous jump cutting device for tape, which sets the blade in a semi-annular shape, and the two blades are combined to form a whole circle. When disassembling, the two blades are separated, and the blades can be replaced without disassembling other blades, thereby shortening the time for replacing the blades. However, the blade is installed on a fixed sleeve, and the fixed sleeve is installed on the main shaft through a second bolt and a positioning groove. The spacing and number of the positioning grooves limit the spacing between multiple fixed sleeves and cannot be infinitely adjusted, thereby resulting in the inability to flexibly adjust the size of the cut tape. In order to solve the above problems, the utility model provides an asynchronous jump cutting device for tape. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Embodiment 1:

[0038] like Figures 1 to 6As shown, the utility model provides an asynchronous jump cutting device for an adhesive tape, comprising a conveyor belt 1 for conveying the adhesive tape, installation frames 2 are provided on both sides of the conveyor belt 1, a main shaft 3 is installed between the two installation frames 2, a plurality of blades 5 are installed on the main shaft 3, a threaded hole 7 is provided on the blade 5, a clamping plate 6 is provided inside the threaded hole 7, a limiting plate 9 is symmetrically fixedly connected to one end surface of the clamping plate 6 located inside the threaded hole 7, and the limiting plate 9 is slidably connected to a limiting groove 10 provided on the inner side wall of the threaded hole 7, so that the clamping plate 6 will not slip out of the inside of the threaded hole 7 when sliding along the axial direction of the threaded hole 7 The threaded hole 7 is internally meshed with an extrusion bolt 8. By rotating the extrusion bolt 8 clockwise, the extrusion bolt 8 can push the clamping plate 6 toward the main shaft 3, so that the clamping plate 6 is pressed against the main shaft 3. At this time, the position of the blade 5 on the main shaft 3 is fixed, and then the cutting work can be performed stably. When it is necessary to adjust the spacing between the multiple blades 5, the extrusion bolt 8 can be rotated counterclockwise so that the clamping plate 6 is no longer pressed against the main shaft 3. At this time, the blade 5 can be slid on the main shaft 3 along the axial direction of the main shaft 3, and the spacing between the multiple blades 5 can be infinitely adjusted, so that the size of the cut tape can be flexibly adjusted.

[0039] The cross section of the main shaft 3 is a polygon (a hexagon as shown in the figure), so that the blade 5 can be fixed by using the clamping plate 6 to press against the main shaft 3, and the blade 5 can also be stably driven to rotate to achieve cutting.

[0040] Embodiment 2:

[0041] Further, on the basis of the first embodiment, in order to realize the rapid disassembly and assembly of the blade 5, the blade 5 is in the form of splicing, specifically, as follows:

[0042] The blade 5 includes a main blade 501 and an auxiliary blade 502. An opening is provided on the main blade 501. The main blade 501 is sleeved on the main shaft 3 through the opening. The width of the opening is the same as the distance between the two planes of the main shaft 3. The auxiliary blade 502 is installed inside the opening, and the auxiliary blade 502 and the main blade 501 cooperate with each other to clamp the main shaft 3. After the main blade 501 is sleeved on the main shaft 3, it can remain stable, thereby facilitating the staff to install the auxiliary blade 502.

[0043] A groove 503 is provided on the side of the main knife 501, and an insertion rod 504 adapted to the groove 503 is provided on the auxiliary knife 502. The insertion rod 504 can be inserted into the interior of the groove 503 to play a limiting role, so that the side of the auxiliary knife 502 is flush with the side of the main knife 501. Through holes are provided on the insertion rod 504 and the groove 503. During installation, the fixing bolt can be passed through the through hole and then the nut can be screwed on, so that the main knife 501 and the auxiliary knife 502 can be stably connected together.

[0044] During disassembly, the fixing bolts can be removed, and then the auxiliary knife 502 can be taken out from the inside of the opening, and then the main knife 501 can be directly removed. The current blade 5 can be quickly disassembled without affecting it and the blade 5.

[0045] Embodiment three:

[0046] On the basis of the second embodiment, in order to make the cutting effect of the blade 5 on the tape better, a pressing spring 14 is provided to enable the blade 5 to press against the tape, specifically, as follows:

[0047] The two end surfaces of the main shaft 3 are fixedly connected with the mounting shaft 11, and the side surface of the mounting shaft 11 is rotatably connected with a slider 12. The slider 12 is slidably connected in a slide groove 13 provided on the mounting frame 2, and a clamping spring 14 is connected between the slider 12 and the groove wall of the slide groove 13. One end of the clamping spring 14 is fixedly connected to the groove wall of the slide groove 13, and the other end is fixedly connected to the slider 12. The clamping spring 14 has a clamping force to press the slider 12 against the conveyor belt 1. Under the action of the mounting shaft 11 and the main shaft 3, the blade 5 can press against the tape on the conveyor belt 1, thereby improving the cutting effect of the blade 5 on the tape.

[0048] Any mounting shaft 11 is fixedly connected to the motor shaft of the cutting motor 4, and a support spring 15 is connected between the motor seat of the cutting motor 4 and the inner wall of the corresponding mounting frame 2. The setting of the support spring 15 can make the height of the main shaft 3 change under the action of the clamping spring 14, and the height of the cutting motor 4 will follow the corresponding change, thereby not affecting the cutting motor 4 driving the main shaft 3 to rotate.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
