Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tape cutting, in particular to a heating slitting device. Background Technique
[0002] For multi-layer tape products, according to process requirements, it is necessary to cut one or several layers of the tape. For example, for indwelling needle stickers, common indwelling needle stickers are composed of two layers of release paper and an intermediate PU film. According to process requirements, the indwelling needle sticker needs to cut the upper release paper and the intermediate PU film, and keep the lower release paper uncut. Specifically, by adjusting the distance between the cutting knife and the tape, and then using a traction device to traction the tape forward, so that the cutting knife cuts the upper release paper and the intermediate PU film.
[0003] Traditional cutting knife cutting is mainly through physical normal temperature cutting, using the sharp edge of the cutting knife to directly cut the material. The forward speed of the tape of the indwelling needle sticker production equipment is often relatively fast, so that the slitting of the tape by the cutting knife is completed in a very short time, the cutting speed is relatively fast, and the hardness of the PU film is relatively high, resulting in incomplete cutting of some of the upper release paper and the intermediate PU film, and there is a situation of partial connection. At the same time, during the cutting of the upper release paper and the intermediate PU film, the upper release paper and the intermediate PU film will inevitably be deformed by force, resulting in uneven slitting. If the cutting knife is not sharp enough or used for too long, it will also lead to a decline in the cutting effect.
[0004] Therefore, a heating slitting device for solving the above problems is needed. Content of the Utility Model
[0005] The utility model provides a heating slitting device, which slits the tape by heating the cutting knife. After heating, the cutting knife can locally heat and soften the tape, making the material to be cut easier to cut, ensuring continuous and complete cutting of the tape, and ensuring the uniformity of the tape slitting.
[0006] The technical solution of the utility model is realized as follows:
[0007] The heating slitting device includes a support frame, on which a plurality of mounting seats are slidably installed along the Y-axis direction. On each mounting seat, a mounting block is slidably installed along the Z-axis direction. A differential head is arranged between each mounting seat and the corresponding mounting block. A cutting knife is installed at the lower end of each mounting block. A heating component for heating the cutting knife is installed on each mounting block. A support roller is rotatably installed on the support frame.
[0008] As a preferred technical solution, each of the heating components includes two heat insulation plates fixedly installed on the corresponding mounting blocks, a heating block is fixedly installed between the two heat insulation plates, a plurality of electric heating rods are fixedly installed on each heating block, each cutting knife is fixedly installed between the corresponding heating block and one of the adjacent heat insulation plates, and each cutting knife is in contact with the adjacent heating block.
[0009] As a preferred technical solution, a plurality of heating cavities are provided on each heating block, one electric heating rod is provided in each heating cavity, and a limiting plate for limiting the electric heating rod is fixedly installed on each mounting block.
[0010] As a preferred technical solution, the housing of each differential head is respectively fixedly installed on the corresponding mounting seat, and the adjusting rod of each differential head is rotatably installed on the corresponding mounting block.
[0011] As a preferred technical solution, a guide rod is arranged on the support frame along the Y-axis, each mounting seat is slidably installed on the guide rod, and at least one locking knob is installed between each mounting seat and the guide rod.
[0012] As a preferred technical solution, a slide rail is arranged on each mounting seat in the Z-axis direction, and each mounting block is slidably installed on the corresponding slide rail.
[0013] As a preferred technical solution, the support roller is arranged below the cutting knife.
[0014] By adopting the above technical solutions, the beneficial effects of the present utility model are as follows:
[0015] Since the heating and slitting device includes a mounting seat, before the slitting process, the position of the mounting seat on the support frame can be adjusted through the locking knob to align the cutting knife with the position to be slit, so as to complete the distance between adjacent slits. After the cutting knife is aligned with the position to be slit, rotate the differential head to make the distance between the cutting knife and the support roller adapt to the thickness of the slit. Heat the cutting knife to a suitable temperature through the electric heating rod. Under the traction of the traction mechanism, the material tape advances, and the heated cutting knife slits the material tape. During the slitting process, while heating the cutting knife and locally heating and softening the material tape with the heat on the cutting knife, the upper release paper and the middle PU film to be cut are cut by the sharp edge of the cutting knife, so as to realize the slitting of the material tape. Compared with directly cutting with the cutting knife, in the present utility model, the cutting knife is heated. The heated cutting knife can soften the material to be cut, reduce the resistance during cutting, further promote the realization of uniform cutting, make the material to be cut easier to be cut, ensure that the material tape is continuously and completely cut, and ensure the uniformity of the slits of the material tape.
[0016] In the present utility model, the cutter is heated to soften the material to be cut, which can also reduce the direct friction between the cutter and the material to be cut, thereby reducing the wear of the cutter, prolonging the service life of the cutter, and saving costs.
[0017] In the present utility model, the temperature of the cutter can also be controlled by an electric heating rod, so as to be applicable to the cutting seams of different materials and improve the application range of the device. BRIEF DESCRIPTION OF THE DRAWINGS
