Description

Technical Field

[0001] The utility model belongs to the technical field of dustproof mesh production, in particular to an edge trimming device for mesh production. Background Art

[0002] Dustproof mesh for electronic equipment plays an important role in protecting electronic equipment from external environmental factors such as dust and moisture. As the name suggests, dustproof mesh for electronic equipment is a dustproof device used on electronic equipment. It is mainly made of special materials, such as thin film materials with microporous structures. It can effectively prevent dust, moisture and other pollutants from entering the interior of electronic equipment, while maintaining good air permeability and ventilation to ensure the normal operation of the equipment; the edge trimming of dustproof mesh is an important link in the production process of dustproof mesh, which is usually carried out by a continuous die-cutting machine. The dustproof mesh roll with a release film on the back is conveyed to the bottom of the die-cutting knife for die-cutting, and the dustproof mesh is cut into a fixed shape. The waste generated by the edge trimming is then peeled off from the release film to achieve edge trimming.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 4 , a trimming equipment for the production of mesh fabrics, including a support device for supporting die-cutting and guiding the conveyance of a dust-proof mesh fabric roll, and further including a die-cutting device provided on the support device for reciprocating movement in both directions for double-pass cutting. Two adsorption devices for sucking and tightening the dust-proof mesh fabric symmetrically are arranged on both sides of the die-cutting device.

[0026] In this embodiment: The support device includes a support frame 101. Two unwinding rollers 102 are symmetrically arranged on both sides of the top of the support frame 101. A winding roller 103 is arranged below the unwinding roller 102. A waste roller 104 is arranged on one side below the winding roller 103. A guiding component is arranged between the two winding rollers 103. Four limiting rods 107 are evenly arranged between the two guiding components. The guiding component includes a fixed frame 105. Two guide rollers 106 are symmetrically arranged on the upper and lower sides of the fixed frame 105. When in use, the dust-proof mesh fabric roll is installed on the unwinding roller 102, and under the support of the support frame 101, the dust-proof mesh fabric bypasses the two guide rollers 106 and one side of the fixed frame 105 and is wound on the winding roller 103. The cut waste is separated from the dust-proof mesh fabric and wound on the waste roller 104. The fixed frame 105 is used to support the adsorption device, and the limiting rod 107 is used for cutting guidance;

[0027] In this embodiment, the adsorption device includes a negative pressure component. A mesh plate 202 is installed on one side of the negative pressure component. The negative pressure component includes a negative pressure box 201. A suction pipe 203 is provided on one side of the negative pressure box 201. A negative pressure pump 204 is installed on the suction pipe 203. The adsorption surface of the mesh plate 202 is tangent to the guide roller 106. The negative pressure pump 204 evacuates the negative pressure box 201 through the suction pipe 203 to create a negative pressure inside, and adsorbs the dust-proof net cloth on the surface of the mesh plate 202.

[0028] In this embodiment, the die-cutting device includes a motor 301. An eccentric disc 302 is installed in front of the motor 301. An eccentric shaft 303 is provided in front of the eccentric disc 302. A limit ring 304 is arranged outside the eccentric shaft 303. Two sliding rods 305 are symmetrically arranged on both sides of the limit ring 304. A cutting component is arranged at one end of the sliding rod 305 away from the limit ring 304. The cutting component includes a mounting plate 306. A die-cutting knife 307 is installed on one side of the mounting plate 306. The motor 301 drives the eccentric disc 302 to drive the eccentric shaft 303 to rotate, so that the eccentric shaft 303 pushes the sliding rod 305 on one side through the limit ring 304 to drive the mounting plate 306 and the die-cutting knife 307 to move along the limit rod 107 towards the dust-proof net cloth on this side. When the eccentric shaft 303 moves to the end of the stroke on this side, the die-cutting knife 307 will cooperate with the mesh plate 202 to cut the dust-proof net cloth on this side under the support of the fixed frame 105. Immediately afterwards, the eccentric shaft 303 will push the sliding rod 305 on the other side through the limit ring 304 to drive the mounting plate 306 and the die-cutting knife 307 to move along the limit rod 107 towards the dust-proof net cloth on the other side, and cut the dust-proof net cloth on this side. At the same time, the cut dust-proof net cloth is wound downwards, a new dust-proof net cloth is pulled down at the cutting station, and the waste cut from the dust-proof net cloth is peeled off and wound around the waste roller 104 through the waste roller 104. Finally, the dust-proof net cloth on both sides is cut alternately through the above process.

[0029] Working principle: When in use, the dust-proof net cloth roll is installed on the unwinding roller 102, and under the support of the support frame 101, the dust-proof net cloth bypasses the two guide rollers 106 and is wound around the winding roller 103 on one side of the fixed frame 105. At the same time, the negative pressure pump 204 pumps air into the negative pressure box 201 through the suction pipe 203 to create a negative pressure inside it, adsorbing the dust-proof net cloth on the surface of the net plate 202; subsequently, the motor 301 drives the eccentric disk 302 to drive the eccentric shaft 303 to rotate, so that the eccentric shaft 303 pushes the slide rod 305 on one side through the limit ring 304 to drive the mounting plate 306 and the die-cutting knife 307 to move along the limit rod 107 towards the dust-proof net cloth on that side. When the eccentric shaft 303 moves to the end of the stroke on that side, the die-cutting knife 307 will cooperate with the net plate 202 to cut the dust-proof net cloth on that side under the support of the fixed frame 105; immediately afterwards, the eccentric shaft 303 will push the slide rod 305 on the other side through the limit ring 304 to drive the mounting plate 306 and the die-cutting knife 307 to move along the limit rod 107 towards the dust-proof net cloth on the other side to cut the dust-proof net cloth on that side. At the same time, the cut dust-proof net cloth is wound downwards, a new dust-proof net cloth is pulled down at the cutting station, and the waste cut from the dust-proof net cloth is peeled off and wound around the waste roller 104; finally, the dust-proof net cloth on both sides is alternately cut through the above process.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
