Description

Technical Field

[0001] This utility model relates to the field of plastic film processing technology, specifically to a cutting device for plastic films. Background Technology

[0002] The plastic film cutting device is used for slitting plastic film. After the film end passes through the cutter on the roller, it is fixed on the take-up roller. The take-up roller is started to take up the film. The film moves along the worktable. During the movement, the cutter on the roller slits the film, and the take-up roller takes up the slit film.

[0003] When cutting plastic film, a plastic film cutting device can be used. For example, a plastic film cutting device is disclosed in Chinese patent literature [Announcement No.: CN221739453U]. When this type of device cuts the film, since there is no restriction on the film, the film may move due to friction between the cutter and the film, which may affect the cutting work of the cutter.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 As shown, a cutting device for plastic film includes a worktable body 1, a plastic body 3 disposed on the surface of the worktable body 1, feeding rollers 2 for driving the plastic body 3 disposed on both sides of the surface of the worktable body 1, side columns 4 fixed on both sides of the surface of the worktable body 1, electric push rods 5 disposed on the surface of the side columns 4, lifting blocks 6 fixed to the other end of the electric push rods 5, cutting blades 7 for cutting the plastic body 3 disposed on the surface of the lifting blocks 6, an adsorption mechanism 8 disposed on one side of the surface of the lifting blocks 6, and an air blowing mechanism 9 disposed on the other side of the surface of the lifting blocks 6. In this invention, when the electric push rod 5 drives the cutting blade 7 to cut the plastic body 3, the adsorption mechanism 8 can be activated in cooperation with the lifting block 6 and the side columns 4, thereby adsorbing the plastic body 3 onto the surface of the worktable body 1, thus improving the stability of the cutting blade 7 when cutting the plastic body 3. In addition, the air blowing mechanism 9 can blow away dust on the surface of the plastic body 3, thereby preventing the presence of dust from affecting the normal cutting of the plastic body 3 by the cutting blade 7.

[0020] The adsorption mechanism 8 includes an airbag 81 fixed to the surface of the lifting block 6. The other end of the airbag 81 is fixed to the surface of the side column 4. One side of the airbag 81 is connected to a connecting air pipe 82, and the other end of the connecting air pipe 82 is connected to a suction pipe 83. A first one-way valve 84 is provided on the surface of the suction pipe 83, and the other end of the suction pipe 83 is connected to a connecting groove 85. The connecting groove 85 is opened in the inner cavity of the workbench body 1, and the surface of the connecting groove 85 is connected to several ventilation holes 86 penetrating the workbench body 1. In this embodiment, the airbag... The arrangement of the connecting air pipe 82, the suction pipe 83, the first one-way valve 84, the connecting groove 85, and the vent hole 86 allows the airbag 81 to stretch when the electric push rod 5 moves the lifting block 6 and the cutting blade 7. Under the action of the airbag 81, the connecting air pipe 82 drives the suction pipe 83 to work. Under the restriction of the first one-way valve 84, and under the action of the suction pipe 83, air flows in the connecting groove 85 and the vent hole 86, which can then adsorb the plastic body 3.

[0021] The number of vent holes 86 is several and they are symmetrical about the cutting blade 7. In this embodiment, this arrangement can improve the adsorption capacity of the vent holes 86 on the plastic body 3 when there is air flow in the vent holes 86, and improve the stability of the adsorption on the plastic body 3.

[0022] The air blowing mechanism 9 includes an air outlet pipe 91 connected to the surface of the connecting air pipe 82. The other end of the air outlet pipe 91 is connected to an air outlet block 92. An air outlet groove is opened on the surface of the air outlet block 92. A second one-way valve 93 is provided on the surface of the air outlet pipe 91. In this embodiment, by setting the air outlet pipe 91, the air outlet block 92 and the second one-way valve 93, when air needs to be vented from the connecting air pipe 82, air can flow out from the air outlet block 92 with the cooperation of the air outlet pipe 91 and the second one-way valve 93, thereby achieving the purpose of blowing away dust from the surface of the plastic body 3.

[0023] The second one-way valve 93 allows air to flow out of the airbag 81, while the first one-way valve 84 allows air to enter the airbag 81.

[0024] One side of the surface of the air outlet block 92 is inclined, and the inclined surface faces the worktable body 1. In this embodiment, this setting makes the air outlet block 92 present a certain angle, which improves the practicality of the air blowing mechanism 9.

[0025] A grid 10 is fixedly provided on the surface of the air outlet block 92. The spacing between the columnar members of the grid 10 is 0.3cm-0.5cm. In this embodiment, the grid 10 can prevent large foreign objects from entering the air outlet block 92, thereby improving the safety of the device.

[0026] Working principle: The worktable body 1 can cut the plastic body 3 through the electric push rod 5, lifting block 6, and cutting blade 7. Its working principle can be referenced in the plastic film cutting device application number CN202420256500.0. When the electric push rod 5 drives the lifting block 6 and cutting blade 7 to rise and fall, the airbag 81 can be squeezed or stretched with the cooperation of the side column 4 and the lifting block 6, thereby allowing the gas in the airbag 81 to be drawn in and expelled. When gas is drawn into the airbag 81, it can be connected to the air pipe 82, the suction pipe 83, and the first one-way valve 84. Under the action of the connecting groove 85 and the vent hole 86, the plastic body 3 on the surface of the workbench body 1 is adsorbed, thereby making the plastic body 3 more stably placed on the surface of the workbench body 1, improving the stability of the cutting blade 7 when cutting the plastic body 3. In addition, when the gas in the air bag 81 is discharged, under the action of the air outlet pipe 91, the air outlet block 92 and the second one-way valve 93, the gas can be discharged from one side of the cutting blade 7 to blow air on the uncut plastic body 3, so as to remove the dust on the surface of the plastic body 3 and avoid the dust from affecting the cutting of the plastic body 3.
