Description
Technical Field
The utility model belongs to the technical field of the winding membrane processing and specifically relates to a winding membrane rip cutting knife tackle is related to.
Background
In the production and processing process of the winding film, the width of the whole film is large before cutting, and the winding film needs to be longitudinally cut on line according to needs, so that the winding film with the required width is obtained. The existing equipment processing has two problems, the cutter set is of a fixed structure, the position of the cutter set is fixed on the equipment, the distance cannot be adjusted, and the width of the winding film processing cannot be adjusted. Secondly, when a certain blade is damaged, equipment is required to be stopped to replace the blade, so that production can be carried out, the machining continuity is affected, and the maintenance cost of the equipment is improved.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a winding membrane slitting knife tackle solves current winding membrane slitting knife tackle unadjustable, needs to shut down the change, problem that the maintenance cost is high.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a winding membrane slitting knife group, includes the frame, the frame is provided with a set of slitting knife unit of cutting apart into required width with the winding membrane along the width direction of winding membrane interval, slitting knife unit includes the knife rest, be provided with two at least cylinder block on the knife rest side by side, be provided with the telescopic push rod in every cylinder block respectively, set up the blade fixing base on the push rod, install the rip cutting blade on the blade fixing base.
In order to prevent the damage caused by the misoperation of an operator, a protective cover covering the periphery of the longitudinal cutting blade is fixedly arranged on the tool rest.
For the width of convenient adjustment winding membrane cutting, be provided with the slide rail in the frame, fixedly connected with and the slider of slide rail looks adaptation on the knife rest.
In order to conveniently and quickly install the air cylinder and ensure the position of the longitudinal cutting blade, the air cylinder seat is of a flat structure, and the knife rest is provided with a slot matched with the air cylinder seat.
The utility model has the advantages that: the utility model arranges two longitudinal cutter pieces at the same longitudinal cutting position of the winding film on the tool rest, one longitudinal cutter piece works and the other longitudinal cutter piece is used as a standby, and meanwhile, the longitudinal cutter pieces are controlled by the air cylinder to move up and down; when the working longitudinal cutting blade is damaged, the other longitudinal cutting blade is controlled to move downwards through the air cylinder, so that the other longitudinal cutting blade acts on the winding film to complete cutting, and then the damaged longitudinal cutting blade is lifted up through the air cylinder. The whole replacement process is simple and convenient to operate, and does not need to be stopped for maintenance, so that the continuity of winding film processing is ensured, the continuity of production is improved, and the maintenance cost is reduced. The damaged longitudinal cutting blade is taken out of the tool rest through the cylinder seat, and then the tool rest is installed again after the longitudinal cutting blade is replaced, so that the longitudinal cutting blade is used for the next time and is convenient to replace. The protection casing can guarantee that operating personnel can not touch the slitting blade when the operation to guarantee operating personnel's security. The tool rests are connected with the sliding blocks, and the rack is provided with the sliding rails, so that each tool rest can move back and forth on the sliding rails, and the width of the wound film can be conveniently adjusted.
The present invention will be described in more detail with reference to the accompanying drawings and examples.

Fig. 2 is a schematic view of the three-dimensional structure of the middle slitting knife unit in which the blade on one cylinder block works and the blade on the other cylinder block does not work.
Detailed Description
Example, as shown in fig. 1 and 2, a wrapping film slitting knife assembly is used to longitudinally cut a continuously processed wrapping film to obtain a set of wrapping films having a desired width. This slitting knife group includes frame 1, sets up the slide rail 101 in frame 1, be provided with a set of slider 3 that can make a round trip to slide on slide rail 101 on the slide rail 101, still be provided with the graduation apparatus on the slide rail 101, make things convenient for the distance between the position of calibration slider 3 and two sliders 3, install the slitting knife unit 2 that accomplishes winding film and vertically cut off on the slider 3, can adjust the distance between slider 3 according to the needs of winding film width processing, obtain the winding film product of required width.
The longitudinal cutter unit 2 comprises a cutter frame 201 fixedly arranged on the sliding block 3, and at least two cylinder bases 202, preferably two cylinder bases, are arranged on the cutter frame 201 side by side. Each cylinder block 202 is internally provided with a telescopic push rod 203 and a blade fixing seat 204 arranged on the push rod 203, and the blade fixing seat 204 is provided with a longitudinal cutting blade 205. The push rod 203 drives the blade holder 204 to extend and retract. In order to ensure the installation position of the longitudinal cutting blade 205, the cylinder block 202 is of a flat structure, the tool holder 201 is provided with a slot 207 matched with the cylinder block 202, and the cylinder block 202 is installed in the slot 207, so that the position accuracy is ensured, and meanwhile, the longitudinal cutting blade is convenient to disassemble and assemble. The cutting edges of the two longitudinal cutting blades 205 are located at the same longitudinal cutting position of the winding film, one longitudinal cutting blade 205 extends out under the action of the cylinder to longitudinally cut off the winding film, the other longitudinal cutting blade 205 retracts under the action of the cylinder and serves as a spare blade, when the longitudinal cutting blade in processing needs to be replaced, the spare blade is directly driven by the cylinder to act on the winding film in a downward mode, continuous cutting of the winding film is completed, the other longitudinal cutting blade is moved upwards through the cylinder to retract without participating in cutting, the cylinder seat 202 is taken out of the knife rest 201 to replace the longitudinal cutting blade, shutdown maintenance is not needed in the whole process, the continuity of processing of the winding film is guaranteed, the operation is simple, the convenience is achieved, and the maintenance cost is greatly reduced.
In order to prevent the longitudinal cutting blade from cutting the operator, a protective cover 206 covering the periphery of the longitudinal cutting blade 205 is fixedly arranged on the tool rest 201.
The invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above-described manner. Various insubstantial improvements are made by adopting the method conception and the technical proposal of the utility model; or without improvement, the above conception and technical solution of the present invention can be directly applied to other occasions, all within the protection scope of the present invention.
