AI Technical Summary
Existing packaging film slitting machines lack guiding devices when packaging steel coils, causing the packaging film to deviate from its direction, resulting in poor local stretching and flatness, and failing to meet the requirements for high flatness.
The feeding direction is adjusted by a guide section, and the flatness of the packaging film is improved by a double pressing device. Combined with the adjustable guide section position and the double pressure roller structure, the packaging film is precisely cut.
It achieves high flatness and longitudinal cutting accuracy of packaging film, meets the transportation requirements of steel coil packaging, and can arbitrarily set the width and length cutting scheme of film.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to mechanical field, concretely is a slitting machine. BACKGROUND
[0002] In the steel coil transportation technical field, the packing specification of steel coil is different, therefore, the specification of packing film is also different accordingly. In addition, the flatness of packing film is required to be higher when packing the steel coil. The existing packing film slitting machine often cannot meet the use requirement, causing the waste of product. CONTENT OF THE UTILITY MODEL
[0003] In order to solve the above technical problem, the inventor found that the packing film of the existing slitting machine does not have a guiding device, and is only pressed flat by a pair of pressure rollers, which often causes the packing film to deviate from the direction, causes local stretching, and further causes poor flatness. Therefore, the utility model adopts a guiding part to adjust the feeding direction, and the position of the guiding part is adjustable; and adopts a double pressure device to pack the flatness and longitudinal cutting precision of the packing film. The specific technical scheme is as follows:
[0004] A steel coil packing film slitting machine with adjustable size, comprising a guiding part, a longitudinal cutting part and a transverse cutting part, the guiding part is provided with a pair of baffle plates, the lower end of the baffle plate is screw-connected with an adjusting screw, the screw directions of the two baffle plates are opposite; the two ends of the screw are fixed on the guiding part frame; the longitudinal cutting part comprises a longitudinal cutting knife shaft, a pair of longitudinal cutting knives are arranged on the longitudinal cutting knife shaft; the two ends of the longitudinal cutting knife are provided with a first pressure roller and a second pressure roller, the two ends of the first pressure roller and the second pressure roller are fixed on the frame of the longitudinal cutting part; the transverse cutting part is provided with a rack, the rack is meshed with a driving wheel on the output shaft of the cutting knife motor, the cutting knife motor is arranged on a sliding block, and a transverse cutting knife is arranged below the sliding block.
[0005] The first pressure roller and the second pressure roller each comprise two pressure roller shafts arranged above and below, the upper end of the pressure roller shaft is fixed in the inner ring of the bearing, the bearing is fixed on the sliding plate through a pressure ring, the two ends of the sliding plate are embedded in the slide of the support, and the upper end of the sliding plate is connected with the piston end of the air cylinder fixed on the support; the two pressure roller shafts arranged above and below are meshed through a gear.
[0006] A screw thread is arranged on the longitudinal cutting knife shaft, and nuts are arranged at the two ends of the longitudinal cutting knife, the longitudinal cutting knife is fixed on the longitudinal cutting knife shaft through the nuts arranged at the two ends.
[0007] The two ends of the longitudinal cutting knife shaft are fixed on the sliding plate, and the upper end of the sliding plate is connected with the piston end of the air cylinder fixed on the support.
[0008] The utility model has the advantages that the width and length cutting scheme of the packing film can be arbitrarily set, the flatness of the packing film is higher, and the requirements of steel coil packing and transportation are met. BRIEF DESCRIPTION OF DRAWINGS
