Description

Technical Field

[0001] The utility model specifically relates to the technical field of adhesive tape slitting machines, in particular to a knife frame assembly of a multifunctional adhesive tape slitting machine. Background Art

[0002] Adhesive tape is a strip of adhesive material that is widely used in daily life and many industrial fields. After production, the tape is generally produced in a cylindrical tape mother roll. In order to adapt to different applications, the tape mother roll needs to be cut using a tape slitting machine. The tape slitting machine is a device used to cut wide tape materials into narrow tapes. The tape mother roll is driven by a rotating mechanism to rotate at a constant speed, and the tape mother roll is cut in cooperation with the same rotating slitting mechanism.

[0003] However, in practice, the slitting knives of the tape slitting machine are usually circular blades, which are arranged according to the required width spacing. When the tape passes through the knife, the blade will cut the tape into multiple narrow tapes. These blades can be fixed or adjustable, which is convenient for setting according to different slitting width requirements;

[0004] Since there are multiple blades installed on the slitting tool, the position of the blades needs to be adjusted one by one when adjusting the width of the tape, and the distance between the blades needs to be measured one by one using a measuring tool during the adjustment process, which takes a long time. In addition, when slitting tapes of the same width, the adjustment of the blades one by one is likely to affect the accuracy between the blades, thereby affecting the slitting effect of the tape mother roll. Utility Model Content

[0005] The purpose of this utility model is to provide a tool holder assembly for a multifunctional tape slitting machine. The assembly connects the support slides provided at the bottom of all the tools through multiple sets of equally spaced movable frames. In conjunction with a threaded screw, the multiple tools can be moved at equal intervals, eliminating the need for individual measurement and adjustment, thereby improving adjustment efficiency and accuracy. This solves the technical problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A tool holder assembly for a multifunctional tape slitting machine includes an outer frame, a threaded screw movably connected to the outer frame, a servo motor fixedly connected to one end of the outer frame, and an end of the servo motor passing through the outer frame and connected to the threaded screw via a coupling;

[0010] A threaded sleeve is installed at the through hole of the support slide seat close to the servo motor side, and the threaded sleeve is threadedly connected to the threaded screw.

[0011] As a further technical solution of the present invention, the bottom of the T-shaped base is fixedly connected to a positioning pin shaft column which is movably connected to the equally spaced movable frame. The end of the T-shaped base is integrally provided with a support vertical plate for supporting the slitting knife assembly, and the support vertical plate is movably connected to both ends of the slitting knife assembly.

[0012] As a further technical solution of the present invention, the slitting knife assembly includes a slitting blade, and a rotating shaft is integrally provided at the center of the slitting blade. Both ends of the rotating shaft are interference fit with rotating bearings, and the outer ring of the rotating bearing is interference fit with the supporting vertical plate.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-7 The embodiment of the utility model provides a tool holder assembly of a multifunctional tape slitting machine, comprising an outer frame 1, a threaded screw 4 movably connected to the outer frame 1, a servo motor 2 fixedly connected to one end of the outer frame 1, and an end of the servo motor 2 passes through the outer frame 1 and is connected to the threaded screw 4 via a coupling;

[0030] The threaded screw 4 is provided with a supporting slide 5 in a rectangular array, and the supporting slide 5 is slidably connected to the outer frame 1. Each supporting slide 5 is movably connected to a slitting knife assembly 8, and the bottom of the supporting slide 5 is also movably connected to an equally spaced movable frame 6.

[0031] In this embodiment, the support slide 5 includes a T-shaped base 51 slidably connected to the outer frame 1 , a through hole 52 is formed in the T-shaped base 51 , and the threaded screw 4 passes through the inner side of the through hole 52 ;

[0032] A threaded sleeve 9 is installed at the through hole 52 of the support slide 5 near the side of the servo motor 2, and the threaded sleeve 9 is threadedly connected to the threaded screw 4.

[0033] In this embodiment, the bottom of the T-shaped base 51 is fixedly connected to a positioning pin shaft column 54 that is movably connected to the equally spaced movable frame 6. The end of the T-shaped base 51 is integrally provided with a support vertical plate 53 that supports the slitting knife assembly 8, and the support vertical plate 53 is movably connected to both ends of the slitting knife assembly 8.

[0034] In this embodiment, the slitting knife assembly 8 includes a slitting blade 81, and a rotating shaft 82 is integrally provided at the center of the slitting blade 81. Both ends of the rotating shaft 82 are interference fit with rotating bearings 84, and the outer ring of the rotating bearing 84 is interference fit with the supporting vertical plate 53.

[0035] In this embodiment, the end of the rotating shaft 82 passes through the supporting vertical plate 53, a spline sliding hole 83 is opened in the rotating shaft 82, and the inner side of the spline sliding hole 83 is slidingly connected with the spline shaft 7, and both ends of the spline shaft 7 pass through the spline sliding hole 83 and are movably connected to the outer frame 1.

[0036] In this embodiment, a rotary motor 3 corresponding to the spline shaft 7 is fixedly connected to the outer frame 1 , and an end of the rotary motor 3 passes through the outer frame 1 and is transmission-connected to the spline shaft 7 via a coupling.

[0037] In this embodiment, the equally spaced movable frame 6 includes two right rods 61 and left rods 62 that are arranged crosswise with each other, and circular rings are respectively provided at the center positions of the right rod 61 and the left rod 62, and connecting rings 63 are integrally provided at both ends of the right rod 61 and the left rod 62.

[0038] In this embodiment, each group of the equally spaced movable frames 6 is movably connected via a pin, and the pin passes through the connecting ring 63 in the equally spaced movable frames 6 .

[0039] By adopting the above technical solution, the servo motor 2 drives the threaded screw 4 to rotate, and through the threaded cooperation between the threaded screw 4 and the threaded sleeve 9, drives the support slide 5 at the end to move. Since the bottom of each group of support slides 5 is movably connected with an equally spaced movable frame 6, and the right rod 61 and the left rod 62 are cross-arranged with each other in the equally spaced movable frame 6, when a single support slide 5 moves, it can drive all support slides 5 to move at the same time. Each group of equally spaced movable frames 6 is movably connected by a pin shaft, so that when each support slide 5 moves, the spacing between each support slide 5 is the same, realizing equal spacing adjustment, and ensuring that the width of all tapes after slitting is consistent.

[0040] In this embodiment, one end of the outer frame 1 is threadedly connected to a fixing bolt 10 , and the end of the fixing bolt 10 passes through the outer frame 1 and is fixedly connected to the T-shaped base 51 on the side away from the servo motor 2 .

[0041] In this embodiment, a threaded sleeve 9 is threadedly connected to the threaded screw 4, and the threaded sleeve 9 is inserted into the through hole 52 on the side close to the servo motor 2, and the threaded sleeve 9 is fixedly connected to the side of the T-shaped base 51 by screws. The threaded sleeve 9 and the threaded screw 7 are threaded together to drive the T-shaped base 51 to slide on the outer frame 1.

[0042] In this embodiment, the positioning pin shaft column 54 passes through the ring between the right rod 61 and the left rod 62 and is connected to the T-shaped base 51. The right rod 61 and the left rod 62 can rotate at the bottom of the T-shaped base 51 with the positioning pin shaft column 54 as the axis.

[0043] In this embodiment, in the two adjacent groups of equally spaced movable frames 6, the right rod 61 of one group is movably connected to the left rod 62 of the other group through a connecting ring 63, and similarly, the left rod 62 of one group is movably connected to the right rod 61 of the other group through a connecting ring 63, forming a diamond-shaped hinged four-bar mechanism.

[0044] In this embodiment, the slitting blade 81 is located above the T-shaped base 51, the supporting vertical plates 53 are located on both sides of the slitting blade 81, and both ends of the rotating shaft 82 pass through the supporting vertical plates 53. When the T-shaped base 51 moves, the slitting blade 81 can be driven to move at the same time, and the slitting blade 81 can rotate on the T-shaped base 51.

[0045] The working principle of the present invention is as follows: when in use, the outer frame 1 is first installed on the feed mechanism of the tape slitting machine, and the feed mechanism pushes the knife holder assembly closer to the tape mother roll. At the same time, the rotating motor 3 drives a plurality of slitting blades 81 to rotate synchronously through the transmission connection between the spline shaft 7 and the spline slide hole 83 to slit the tape mother roll; when adjusting the slitting width, the servo motor 2 moves the support slide 5 at the end to the left through the threaded fit between the threaded screw 4 and the threaded sleeve 9, and the support slide 5 at the other end is fixedly connected to the outer frame 1 by the fixing bolt 10. The moving support slide 5 drives the equally spaced moving frame 6 set at the bottom to move, and each group of equally spaced moving frames 6 is connected by a pin shaft. It is connected end to end, so the moving support slide 5 can drive each support slide 5 except the one fixedly connected to the outer frame 1 to move, and the right rod 61 and the left rod 62 arranged crosswise with each other form a diamond hinge mechanism with the adjacent right rod 61 and the left rod 62, so that multiple support slides 5 can be moved at equal intervals, and there is no need to adjust the tools one by one, thereby improving the adjustment efficiency and the adjustment accuracy. When the support slide 5 moves, the support vertical plate 53 on the T-shaped base 51 drives the slitting knife assembly 8 to slide on the spline shaft 7, and the sliding fit between the spline shaft 7 and the spline slide hole 8 enables the spline shaft 7 to drive the slitting blade 81 to rotate; the structure is simple, the operation is very convenient, and the labor intensity is effectively reduced.
