Description

Technical Field

[0001] The utility model specifically relates to the technical field of tape slitting, and particularly relates to a tape slitting device with a spacing adjusting mechanism. Background Technique

[0002] In numerous application scenarios, users have different requirements for the width of the tape. For example, in the packaging industry, for the packaging of large cartons, relatively wide tapes may be required, while in some fine packaging occasions, such as small packaging boxes for electronic products, narrower tapes are more convenient to operate. Therefore, after the tape is produced, it needs to be slit by a slitting device. Through slitting, a wide tape master roll can be made into small rolls of various widths to precisely meet the requirements of different users for the tape width.

[0003] However, in practice, it has been noted that the existing slitting devices are only equipped with a set of slitting knives. After slitting a set of tape master rolls, it is necessary to lift them, and then replace them with new tape master rolls for re-cutting. During the entire loading process, the slitting knives are performing slitting operations, and slitting can only be carried out after the new tape master roll is placed in place. As the workers work for a long time, the loading speed will decrease, resulting in a low slitting efficiency of the slitting device. Moreover, the slitting knives are generally fixedly connected to the rollers, and the slitting spacing cannot be adjusted. Only rollers with different spacings can be replaced, resulting in a high cost. Content of the Utility Model

[0004] The purpose of the utility model is to provide a tape slitting device with a spacing adjusting mechanism. By alternately using two sets of slitting knives, it is possible to achieve loading without affecting the slitting work, improve efficiency, and the spacing between the slitting knives can be adjusted to process tape rolls of different widths. To solve the technical problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tape slitting device with a spacing adjusting mechanism includes a frame body. A central shaft is fixedly connected to the center position of the frame body. Symmetric extension plates are integrally provided on the side of the frame body. Support shafts are movably connected to the ends of both extension plates. One end of the support shaft penetrates through the extension plate and is drivingly connected to a driven gear. A driving gear is drivingly connected between the two driven gears;

[0007] A two-way cutting frame is movably connected to the outside of the central shaft. A feeding sleeve is interference-fitted to the outside of the driven gear. And the two-way cutting frame is located between the two feeding sleeves.

[0008] As a further technical solution of the utility model, the bidirectional cutting frame comprises two groups of end brackets arranged symmetrically, each group of the end brackets comprises two swing frames arranged in a staggered manner, and spline shafts are movably connected in a rectangular array between the two groups of the end brackets.

[0009] As a further technical solution of the utility model, end shafts are integrally arranged at both ends of the spline shaft, and the end shafts are movably connected with both ends of the swing frame through bearings. Adjustable cutting knives are arranged in a rectangular array on each of the end shafts.

[0010] As a further technical solution of the utility model, the adjustable cutting knife comprises a mounting sleeve sleeved on the spline shaft, and the mounting sleeve is slidably connected with the spline shaft. An annular cutting edge is fixedly connected to the outer side of the mounting sleeve.

[0011] As a further technical solution of the utility model, a receiving groove is formed in the side surface of the mounting sleeve, a locking bolt is placed in the receiving groove, and the end of the locking bolt penetrates through the mounting sleeve and fits with the spline shaft.

[0012] As a further technical solution of the utility model, support sliding rods are symmetrically and fixedly connected to the side surface of the frame body, a material taking cross bar is movably connected to the support sliding rods, and each of the material taking cross bars is movably connected to the side surface of the feeding sleeve.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] In this utility model, through the sliding fit between the spline shaft and the mounting sleeve, it is convenient to adjust the position of the mounting sleeve on the spline shaft, so that tape rolls with different widths can be cut. Moreover, the locking bolt is hidden inside the storage groove to fix the position of the mounting sleeve without affecting the cutting depth of the annular cutting edge. In this utility model, through two swing frames arranged in a staggered manner, two sets of slitting tools are formed, and the two sets of slitting tools are used alternately. When one set of tools is replacing the material, the other set of tools is still performing the slitting work, which does not affect the replacement of the tape master roll during the slitting operation and improves the slitting efficiency of the equipment. In this utility model, through the cooperation of the connecting rod and the U-shaped pushing plate, the material taking cross bar slides on the outside of the supporting sliding rod, and the slit tape roll is taken off at one time by the U-shaped pushing plate, improving the discharging efficiency.
