Description

Technical Field

[0001] This utility model relates to the field of cutting devices, and in particular to a film stretching machine film breaking and cutting device. Background Technology

[0002] A film stretching machine is a mechanical device specifically designed for stretching films. Its main function is to stretch plastic films longitudinally or laterally under specific conditions to improve the strength, transparency, and flexibility of the film. It is commonly used in packaging for food, pharmaceuticals, and electronic products. The stretched film often needs to be cut into specified lengths or widths to meet different packaging requirements. Cutting can also remove irregular areas at the edges, making the film edges neat and smooth.

[0003] Traditional film cutting relies on a cutting blade, but if the cutting blade is not sharp enough or does not have enough precision, it can easily lead to uneven film cutting, resulting in burrs or edge pulling, which affects the appearance and quality of the product. Furthermore, when using a cutting blade, the film may experience uneven stretching or wrinkling.

[0004] Therefore, those skilled in the art have provided a film stretching machine film breaking and cutting device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a film stretching machine film breaking and cutting device. This device can move the laser generator via a first threaded block to complete the film cutting, improving cutting accuracy and reducing unevenness at the cut. The suction hood sends the smoke and exhaust gas generated during cutting into a filter box for treatment, preventing adverse effects from the smoke and exhaust gas. The second threaded block and the electric telescopic rod can move the pressure roller and adjust its position to press on the upper side of the film to prevent the film from shifting during cutting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A film stretching machine film breaking and cutting device includes a machine body, a cutting structure is provided on the front side of the upper end of the machine body, and a pressing structure is provided on the rear side of the upper end of the machine body; The cutting structure includes a fixed base, which is fixed to the front side of the upper end of the machine body.

A laser generator is fixedly connected to the front side of the lower end of the first threaded block. A suction hood is fixedly connected to the rear side of the lower end of the first threaded block. A filter box is set at the center of the upper end of the fixed base. A filter is connected to a fixed rod inside the filter box. A fan is fixedly connected to one side of the upper end of the fixed base. The above technical solution allows the No. 1 threaded screw to slide on the outside of the screw body when it rotates, thereby moving the laser generator to complete the cutting of the film. The laser generator facilitates the use of laser beams to cut the film, resulting in higher efficiency and cutting accuracy. The suction hood facilitates the absorption of smoke and exhaust gas generated during cutting and sends it into the filter for filtration.

[0007] Furthermore, the pressing structure includes a bidirectional threaded screw that rotates inside the machine body. Two threaded blocks are threadedly connected to both sides of the outer wall of the bidirectional threaded screw. Limiting blocks are fixedly connected to the front and rear ends of the two threaded blocks. A fixing plate is fixedly connected to the upper end of the two threaded blocks. A pressing roller is provided at the front end of the fixing plate. The above technical solution allows the No. 2 threaded block to slide inward or outward simultaneously when the bidirectional threaded screw rotates, thereby moving the pressure roller closer to the film. The fixed plate facilitates the installation and fixation of the pressure roller on the No. 2 threaded block, so that the roller is located on the upper side of the film and plays a pressing role, preventing the film from shifting during cutting.

[0008] Furthermore, a No. 1 motor is provided on the upper end of one side of the fixed base, and the output end of the No. 1 motor passes through the side wall of the fixed base and is fixedly connected to the No. 1 threaded screw. The above technical solution allows the No. 1 motor to easily drive the No. 1 threaded screw to rotate during operation.

[0009] Furthermore, guide rods are fixedly connected to both the front and rear ends inside the fixed base, and the first threaded block slides on the outside of the guide rods; The above technical solution allows the guide rod to facilitate the movement of the No. 1 threaded block.

[0010] Furthermore, an air intake pipe is fixedly connected to the rear end of the air intake hood, one side of the air intake pipe is fixed to one side of the filter box, and a snap-fit ​​seat is fixedly connected to the rear end of the first threaded block. The above technical solution facilitates the delivery of cutting fumes and exhaust gases into the filter box through the intake pipe.

[0011] Furthermore, a second motor is provided on one side of the machine body, and the output end of the second motor passes through the side wall of the machine body and is fixedly connected to a bidirectional threaded screw. The above technical solution allows the No. 2 motor to easily drive the bidirectional threaded screw to rotate during operation.

[0012] Furthermore, limit grooves are provided at the front and rear ends on both sides of the interior of the machine body, and the limit block slides within the limit grooves. The above technical solution uses a limiting block to limit the movement of the No. 2 threaded block.

[0013] Furthermore, an electric telescopic rod is fixedly connected to the front end of the fixed plate, and the output end of the electric telescopic rod is fixedly connected to the pressure roller; The above technical solution allows the electric telescopic rod to easily extend the pressing roller forward, thus getting closer to the film that needs to be pressed.

[0014] This utility model has the following beneficial effects: 1. The present invention proposes a film stretching machine film breaking and cutting device, which facilitates film cutting through a laser generator and a suction hood. When the No. 1 threaded screw rotates, the No. 1 threaded block drives the laser generator to move, thereby using a laser beam to cut the film. The fan can absorb the smoke and exhaust gas generated during cutting into the suction hood and send it into the filter for filtration. This prevents smoke and exhaust gas from affecting the air environment and the health of workers during the cutting process with higher cutting precision.

[0015] 2. The film stretching machine film breaking and cutting device proposed in this utility model uses a pressure roller to help position the film during cutting. The rotation of the bidirectional threaded screw causes the No. 2 threaded blocks on both sides to move inward or outward simultaneously until they are on both sides of the film. The electric telescopic rod extends and drives the pressure roller to press on the upper side of the film to prevent the film from shifting during cutting, thereby affecting the cutting accuracy.

The first motor 203 facilitates the rotation of the first threaded screw 202 during operation. A first threaded block 204 is threadedly connected to the outer wall of the first threaded screw 202. The first threaded screw 202 facilitates the sliding of the first threaded block 204 on the outside of the screw body during rotation, thereby moving the laser generator 206 to complete the cutting of the film. Guide rods 205 are fixedly connected to both the front and rear ends inside the fixed base 201. The first threaded block 204 slides on the outside of the guide rods 205. The guide rods 205 facilitate the movement of the first threaded block 204. For guiding purposes, a laser generator 206 is fixedly connected to the front side of the lower end of the first threaded block 204. The laser generator 206 facilitates the cutting of the film using a laser beam, resulting in higher efficiency and cutting precision. A suction hood 207 is fixedly connected to the rear side of the lower end of the first threaded block 204. A filter box 210 is set at the center of the upper end of the fixed base 201.

[0020] Reference Figure 1 , Figure 4 and Figure 5The pressing structure 3 includes a bidirectional threaded screw 301, which rotates inside the machine body 1. A second motor 305 is installed on one side of the machine body 1. The output end of the second motor 305 passes through the side wall of the machine body 1 and is fixedly connected to the bidirectional threaded screw 301. The second motor 305 facilitates the rotation of the bidirectional threaded screw 301 during operation. Two threaded blocks 302 are threadedly connected to both sides of the outer wall of the bidirectional threaded screw 301. The threaded blocks 302 facilitate sliding inward or outward simultaneously when the bidirectional threaded screw 301 rotates, thereby moving the pressing roller 308 closer to the film.

The electric telescopic rod 307 facilitates the extension of the pressure roller 308 forward, so that it is closer to the film that needs to be pressed.

[0021] Working principle: During use, the film to be cut is placed on the upper part of the device, with the side to be cut fixed under the two pressure rollers 308. The second motor 305 is started, driving the bidirectional threaded screw 301 to rotate, causing the second threaded blocks 302 on both sides to move inwards or outwards simultaneously until they reach both sides of the film. The electric telescopic rod 307 then extends, driving the pressure rollers 308 to press against the upper side of the film, preventing displacement during cutting and thus affecting cutting accuracy. The laser beam emitted by the laser generator 206 irradiates the film surface; due to the concentrated energy, it rapidly heats the film to its melting point. To quickly complete the cutting, improve cutting accuracy, and reduce physical friction damage to the film, the No. 1 motor 203 drives the No. 1 threaded screw 202 to rotate, which causes the No. 1 threaded block 204 to move the laser generator 206, thereby cutting the film. During the cutting process, the film may generate smoke and exhaust gas. After the fan 212 is turned on, the generated smoke and exhaust gas are absorbed into the suction hood 207 and sent into the filter 211 through the suction pipe 209. The filtered gas is discharged through the exhaust port on the upper side of the fan 212 to prevent smoke and exhaust gas from affecting the air environment and the health of the staff.
