Description

Technical Field

[0001] This utility model relates to the technical field of PE film processing, and in particular to a fully automatic PE film tearing and collection device. Background Technology

[0002] ABS plastic is widely used in the manufacture of water heater casings due to its high strength, good heat resistance, and ease of processing. During production, transportation, and installation, a layer of PE film is usually adhered to the surface of the casing to protect it from scratches and contamination. This PE film needs to be removed before final assembly and welding can begin.

[0003] The shortcomings of existing technology are:

[0004] It mainly relies on manual operation, and the slow film-tearing speed is the bottleneck of the entire production process; at the same time, it requires continuous investment of manpower, resulting in high labor costs.

[0005] Existing semi-automatic equipment is not fully functional and is prone to film breakage or residue during the film removal process, making it impossible to guarantee a 100% removal rate and resulting in unstable performance.

[0006] It is difficult to flexibly adapt to water heater shells of different sizes and specifications, and tooling needs to be frequently changed or adjusted for different products, which is time-consuming and labor-intensive.

[0007] The lack of an integrated and efficient waste membrane collection system, coupled with the disconnect between the stripping and collection processes, prevents true end-to-end automation.

[0008] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a fully automatic PE film tear-off and collection device, making it more valuable for industrial use. Utility Model Content

[0093] A brief description of the working principle or process of this embodiment:

[0094] In practical application, the transfer linear module 102 drives the transfer sliding plate 103 to move to the film cutting start position, the film cutting cylinder 203 descends until the film cutting blade 216 contacts the product, the transfer linear module 102 drives the transfer sliding plate 103 to move to the film cutting end position, the film cutting cylinder 203 rises to its original position, the transfer linear module 102 drives the transfer sliding plate 103 to move to the film rubbing start position, the film rubbing cylinder 207 descends until the film rubbing head 209 contacts the PE film, and the transfer linear module 102... The linear module 102 drives the transfer sliding plate 103 to move to the film-rubbing end position, the film-rubbing cylinder 207 rises to its original position, the linear transfer module 102 drives the transfer sliding plate 103 to move to the film-tearing start position, the film-tearing cylinder 303 descends until the pressure roller 319 contacts the PE film, the linear transfer module 102 drives the transfer sliding plate 103 to move to the film-tearing start position, the film-pulling cylinder 317 extends to clamp the PE film with the pressure roller 319, and the film-tearing cylinder 303 rises to its original position. The transfer linear module 102 drives the transfer sliding plate 103 to move to the film-tearing end position. During this process, the film-tearing gripper 322 of the film-tearing gripper cylinder 321 clamps the PE film, and the film-tearing cylinder 317 retracts to tear the PE film off the pressure roller 319. The transfer linear module 102 drives the transfer sliding plate 103 to move to the safety position, and the film-tearing gripper 322 of the film-tearing gripper cylinder 321 opens to release the PE film. The waste film removal rotary cylinder 4402 drives the waste film removal scraper 440. 3. Press the PE film downwards, start the film take-up motor 4202, extend the waste film removal cylinder 4208 so that the front and rear film take-up rollers 4206 clamp the PE film and wrap the PE film around the film take-up rollers 4206. The waste film lateral movement cylinder 4302 retracts to its original position. The front and rear waste film removal cylinders 4208 act simultaneously to push out the waste film wrapped around the front and rear film take-up rollers 4206. The waste film removal rotation cylinder 4402 drives the waste film removal scraper 4403 to its original position.

[0095] This invention achieves fully automated operation from film cutting and tearing to waste film collection, seamlessly integrating with production lines for continuous operation. The film tearing speed far exceeds that of manual labor, significantly improving production efficiency and directly saving labor costs. It reliably adheres to the edges of the PE film and maintains constant tension during tearing, effectively preventing film breakage or residue, ensuring a near 100% tearing rate and stable quality. It can adapt to ABS shells of different sizes, offering good versatility and eliminating the need for frequent tooling changes for different product models, shortening changeover time and enhancing equipment flexibility. The film cutting, tearing, and waste film collection mechanisms are highly integrated into a single unit, resulting in a compact structure, small footprint, and easy integration into existing automated production lines.
