Fast-cutting wide-width film cutting machine

Abstract

The invention belongs to the technical field of production equipment of quick-cutting wide-width film cutting machines, and discloses a quick-cutting wide-width film cutting machine. The rack is fixed on the ground; the leveling device is fixed with the rack; the upper roller set and the lower roller set rotate through chain transmission and belt transmission. The feeding roller group is fixed on the rack; the pneumatic control system is used for adjusting the gap between the upper roller set and the lower roller set and meanwhile used for sudden stop of the cutter assembly. And the protective cover is fixed outside the transmission mechanism. Rollers of the upper roller set and the lower roller set are the same in rotating speed and opposite in rotating speed so as to guarantee that the film can be compressed and conveyed to a cutter to be cut in the equipment running process. Air cylinders are installed at the two ends of a roller of the upper roller set and used for adjusting the gap between the upper roller set and the lower roller set, and the situation that the folded film is too large in thickness and cannot smoothly pass through the space between the two roller sets to be cut due to too large breadth is avoided. The structure of the feeding roller set achieves the guiding effect, and the film is prevented from deviating from the target track due to the too high rotating speed of the device. Motors of the upper and lower roller groups and the cutter are independent, so that the production speed of producing films with different lengths can be realized.

Description

Technical Field

[0001] The invention relates to the technical field of production equipment for a fast-cut wide-width film cutting machine, and in particular to a fast-cut wide-width film cutting machine which is used for crushing unqualified films of PVB glass interlayer films and then recycling them. Background Art

[0002] The storage of PVB glass interlayer film requires that the finished films be stored separately. The scrapped finished rolls need to be crushed, recycled and mixed for reuse. Therefore, when the film needs to be crushed, because the film is rolled and too long, a machine is needed to cut the rolled film and transport it to the crusher for crushing. The motors of the upper and lower roller groups control the speed of the rollers and the motor of the cutter assembly controls the movement frequency of the upper cutter to achieve the production of sheet films of different widths. Summary of the invention

[0003] The purpose of the present invention is to develop a fast-cut wide-width film cutting machine for producing sheet-like films, so as to solve the problem that the films are too wide and too long to be directly fed into a crusher for crushing.

[0004] The technical solution of the present invention is as follows: a fast-cut wide-width film cutting machine, comprising a frame 1, an upper roller group 2, a lower roller group 3, a chain drive 4, a belt drive 5, a feed roller group 6, a cutter assembly 7, a protective cover 8, and an air control system 9;

[0005] The frame 1 is fixed, and an upper roller group 2, a lower roller group 3, a feed roller group 6, a cutter assembly 7, a protective cover 8 and an air control system 9 are fixedly connected thereto;

[0006] The upper roller group 2 and the lower roller group 3 are arranged up and down to form an upper and lower roller group, each of which is composed of a plurality of rollers, one end of which is connected by a plurality of identical pulleys through a belt to form a belt drive 5, and the other end is connected by two identical sprockets. Another group of chains is sequentially wound around the upper roller group 2 and the lower roller group 3 to drive the upper and lower roller groups to rotate, forming a chain drive 4, so that the upper and lower roller groups have the same rotation speed and opposite directions;

[0007] The feed roller group 6 is located at the front end of the upper and lower roller groups, and is composed of 4 rollers, two of which are installed in a V shape, and the other two rollers are installed horizontally, respectively located at the front end and the rear end of the V-shaped roller; the roller at the front end can be moved up and down to adjust the height;

[0008] The cutter assembly 7 is mainly composed of an upper cutter, a lower cutter, a motor, a pulley, a belt, an active shaft, an output shaft, an eccentric wheel, and a sliding bearing; the motor is connected to the output shaft, and the output shaft is connected to the pulley; the belt is wound around the pulley and the eccentric wheel in a circle; the eccentric wheel is connected to the active shaft, and the active shaft slides along the sliding bearing; the upper cutter is connected to the active shaft; the lower cutter is fixed;

[0009] The motor drives the pulley on the output shaft through the belt, which in turn causes the eccentric wheel to rotate; the rotation of the eccentric wheel drives the active shaft to slide up and down through the sliding bearing, which in turn drives the upper cutter to move vertically, while the lower cutter remains stationary;

[0010] Further, a pneumatic control brake is installed on the output shaft of the cutter assembly;

[0011] Furthermore, cylinders are installed at both ends of the rollers of the upper roller group to adjust the gap between the upper and lower roller groups;

[0012] The protective cover 8 is installed on the periphery of the chain drive 4, the air control system 9 and the outside of the frame.

[0013] The fast-cut wide-width film cutting machine further comprises a leveling device 10 installed at the bottom of the frame 1 .

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The upper and lower roller groups are respectively equipped with sprockets and pulleys to ensure that the rollers between the two roller groups have the same rotation speed and the same direction. At the same time, driven by another set of sprockets, the upper and lower roller groups have the same rotation speed and opposite direction. This solution is used to ensure that the film can be compressed and then transmitted to the tool for cutting during the operation of the equipment.

[0016] A pneumatic brake is installed on the output shaft of the cutter assembly to stop the upper flying cutter in an emergency to ensure safety.

[0017] Cylinders are installed at both ends of the upper roller group to adjust the gap between the upper and lower roller groups to prevent the film from being too thick after folding due to excessive width and thus being unable to pass smoothly between the two roller groups and being cut.

[0018] Install a protective cover on the outside of the transmission mechanism to prevent accidental involvement and danger.

[0019] The structure of the feed roller group realizes a guiding function to prevent the device from rotating too fast and causing the film to deviate from the target track.

[0020] The motors of the upper and lower rollers and the cutter are independent, so that the production rate of films of different lengths can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] like Figure 1 As shown, the fast-cut wide-width film cutting machine for producing sheet-shaped films comprises: a frame 1, an upper roller group 2, a lower roller group 3, a chain drive 4, a belt drive 5, a feed roller group 6, a cutter assembly 7, a protective cover 8, a pneumatic control system 9, and a leveling device 10. The frame 1 is fixed to the ground by expansion bolts; the leveling device 10 is fixed to the frame 1 by bolts; the upper roller group 2 and the lower roller group 3 rotate by the chain drive 4 and the belt drive 5; the feed roller group 6 is fixed to the frame 1; the pneumatic control system 9 is used to adjust the gap between the upper roller group and the lower roller group, and is also used for the emergency stop of the cutter assembly 7; the protective cover 8 is fixed outside the transmission mechanism.

[0028] Preferably, the cutter assembly 7 is composed of an upper cutter, a lower cutter, a motor, a pulley, a belt, a connecting shaft, an active shaft, an output shaft, an eccentric wheel, and a sliding bearing. The motor drives the pulley on the output shaft through the belt, thereby rotating the eccentric wheel, so that the active shaft slides up and down through the sliding bearing, thereby driving the upper flying cutter to move vertically.

[0029] Preferably, the feed roller set 6 is a bilaterally symmetrical structure, consisting of four rollers, butterfly nuts, a mounting frame, and a support frame, so as to ensure that films of different widths can smoothly enter the upper and lower roller sets and be cut by a knife.

[0030] Preferably, the chain drive 4 is composed of a sprocket, a chain, a tensioning wheel, and a tensioning device. The upper and lower roller groups rotate at the same speed and rotate in opposite directions, thereby achieving film compression and transmission. The chain connecting the upper and lower roller groups passes through one side of the upper roller group and then goes around to the other side of the lower roller group, thereby making the upper and lower roller groups rotate in opposite directions.

[0031] Preferably, the pneumatic control system is composed of two cylinders, a pneumatic brake and a brake disc. The cylinder is used to adjust the gap between the upper and lower rollers to prevent the film from being too thick after folding and compression and failing to pass through the upper and lower rollers smoothly; the pneumatic brake is used for safety protection and can stop the upper cutter from working in time when needed.

[0032] Preferably, the fast-cut wide-width film cutting machine for producing sheet-like films is characterized in that:

[0033] Start the motors of the upper and lower roller groups, and the motors drive the upper roller group 2 and the lower roller group 3 to rotate, thereby driving the folded film from the feed roller group 6 to be compressed and conveyed; when working, start the motors of the upper and lower roller groups, and the film is pulled into the middle of the upper and lower roller groups by the friction between the upper and lower roller groups 2 and 3 and the film through the feed roller group 6, thereby being compressed; start the motor of the cutter assembly 7, and the upper cutter moves vertically under the operation of the motor, while the lower cutter remains stationary, and the compressed film passes through the middle of the two cutters and is thereby cut off.

[0034] The upper roller group 2 is composed of 4 rollers with the same roller diameter and length, a chain drive 4, a belt drive 5, and a rolling bearing, so that the four rollers can have the same direction and rotation speed.

[0035] The lower roller group 3 is composed of 4 rollers with the same roller diameter and length, a chain drive 4, a belt drive 5, and a rolling bearing, so that the four rollers can have the same direction and rotation speed.

[0036] The structural layout of the feed roller group 6 ensures that films of different widths can smoothly enter between the upper and lower roller groups, and thus be transported between the two flying knives to achieve the cutting effect; and ensures that the film does not deviate from the expected trajectory when the device is running at high speed, thereby ensuring its stability.

[0037] In addition, the above description is only explained according to the implementation mode, not all implementation modes. Based on the implementation mode of the present invention, technicians in this field should understand that modifications or equivalent substitutions that do not depart from the purpose and scope of this implementation mode are covered within the protection scope of the present invention.
