Description

Technical Field

[0001] This utility model relates to the field of hot cutting machine technology for polymer film materials, and in particular to a hot cutting machine for processing PVC car color change film. Background Technology

[0002] Car wrapping film generally refers to car body wrapping film. It is a service that uses a variety of colors and thin films to change the appearance of the entire car or a part of it by covering and pasting it on. The car wrapping film is mainly made of polymer materials and is easy to remove. The film structure of the car wrapping film generally includes a transparent film layer and a colored film layer. The transparent film layer is attached to the upper surface of the colored film layer, and the lower surface of the colored film layer has a release film attached to the adhesive backing. After peeling off the release film, the car wrapping film can be applied to the car body.

[0003] According to the announcement number CN219485901U, a hot cutting machine for PE film processing is proposed. Through the cooperation of components such as rectangular blocks, worm gears, worm wheels, threaded tubes, threaded rods, sliding blocks, and locking blocks, when two adjacent threaded tubes rotate, the threaded rods that move in the inner cavities of the adjacent threaded tubes cause the adjacent sliding blocks to move to the opposite side under the limitation of the adjacent third sliding grooves and third sliders. This causes the locking blocks fixed on the adjacent sliding blocks to move away from the inner cavities of the adjacent locking grooves, which facilitates the disassembly and cleaning of the cutting blade and improves the subsequent cutting effect of the device.

[0004] However, the cutting blade of this hot cutting machine can only be replaced after use to avoid the influence of the adhesive. During use, adhesive residue from the color-changing film will remain on the surface of the cutting blade and gradually accumulate. This adhesive residue not only affects the cutting quality but may also cause the cutting blade to stick to the color-changing film. Stopping the machine to clean the adhesive residue reduces the processing efficiency of the color-changing film.

[0005] Therefore, there is an urgent need to provide a hot-cutting machine for processing PVC car color-changing film to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a hot cutting machine for processing PVC car color change film.

[0007] To solve the above technical problems, the present invention provides a hot cutting machine for processing PVC car color change film, including a hot cutting base, on both sides of the top of the hot cutting base, and a lifting top plate is fixedly installed on the top of the two supporting side plates. A mounting shell is fixedly installed on one side of the support side plate, and a scraping mechanism for automatically collecting the adhesive of the color-changing film is provided inside the mounting shell. The exterior of the lifting top plate is equipped with a cutting mechanism to improve the quality of the color-changing film product, and a hot cutting blade is provided at the bottom of the cutting mechanism.

[0008] The present invention is further configured such that: the scraping mechanism includes a rotary motor fixed to the top of the mounting housing, and the output shaft of the rotary motor is fixedly connected to a mounting worm gear with one end penetrating through and extending into the interior of the mounting housing via a coupling.

[0009] The above technical solution enables the rotary motor to drive the mounted worm gear to rotate.

[0010] The present invention is further configured such that: a pipe shaft with both ends penetrating and extending to the outside is rotatably installed between the two supporting side plates; a mounting worm gear is fixedly installed at one end of the pipe shaft; the mounting worm gear meshes with a mounting worm; a scraper shell is fixedly installed on the outside of the pipe shaft; and the pipe shaft is connected to the scraper shell.

[0011] Through the above technical solution, the worm gear drives the pipe shaft to rotate 180 degrees via the worm wheel, and the pipe shaft drives the scraper housing to scrape off the color-changing film adhesive on the arc side of the hot cutting blade.

[0012] The present invention is further configured such that: a suction fan is fixedly installed on the other side of the supporting side plate, the suction port of the suction fan is rotatably connected to the pipe shaft, and a scraper strip is fixedly installed between the two supporting side plates.

[0013] Through the above technical solution, the suction fan creates a negative pressure inside the scraper housing through the pipe shaft, causing the scraped color-changing film adhesive to move into the scraper housing, and the scraper strip scrapes off the other side of the hot cutting blade.

[0014] The present invention is further configured such that: the cutting mechanism includes a lifting cylinder fixed to the top of the lifting top plate, one end of the piston rod of the lifting cylinder is fixedly mounted with an mounting plate, the top end of the mounting plate is fixedly mounted with a lifting slide rod, and the outside of the lifting slide rod is slidably connected to the inside of the sliding sleeve of the lifting top plate.

[0015] Through the above technical solution, the lifting cylinder drives the mounting plate to rise and fall, and the mounting plate rises and falls stably inside the lifting top plate sliding sleeve through the lifting slide rod.

[0016] The present invention is further configured such that: two spring rods are fixedly installed at the bottom end of the mounting plate, a rebound plate is slidably installed on the outside of the two spring rods, and a columnar spring is fixedly connected between the rebound plate and the mounting plate.

[0017] Through the above technical solution, the mounting plate drives the spring plate to rise and fall accordingly. After the spring plate is pressed, it squeezes the cylindrical spring to prevent the hot cutting blade from deforming under force.

[0018] The present invention is further configured such that: a connecting rod is fixedly installed at the bottom end of the rebound plate, one end of the connecting rod is fixedly connected to the top end of the hot cutting blade, and a heating tube is installed inside the hot cutting blade.

[0019] Through the above technical solution, the heating tube heats the hot cutting blade, and the spring plate drives the hot cutting blade to hot cut the color-changing film through the connecting rod.

[0020] The beneficial effects of this utility model are as follows: 1. This utility model has a scraping mechanism that can automatically scrape off the adhesive of the color-changing film on both sides of the hot cutting blade. The suction fan moves the adhesive into the scraper shell, effectively removing the adhesive residue on the surface of the cutting blade, ensuring the cutting quality. It does not require manual shutdown to clean the adhesive of the color-changing film, ensuring the continuity of color-changing film processing and greatly improving processing efficiency. 2. This utility model, by providing a cutting mechanism, can drive a hot cutting blade to hot cut the color-changing film. By avoiding the influence of adhesive residue on the cutting quality, the cut color-changing film has neat edges and no burrs, thus improving the quality stability of the product.
