In the production and processing of plastics, laser cutting devices are usually required to cut plastics.

[0003] For example, a laser cutting device for plastic products with the announcement number "CN221791414U" fixes the plastic products to a frame through a clamping mechanism when cutting plastic products to prevent the plastic products from shifting during the cutting process, thereby affecting the cutting accuracy. The plastic products can be cut at any position by using a first adjustment component and a second adjustment component in combination, so as to meet the requirements of complex shapes and high-precision cutting. However, when the laser cutting device for plastic products needs to cut at an inclined angle according to special needs, the angle of the cutting blade needs to be manually adjusted by the operator, which takes a long time to adjust, thereby reducing the working limitations. At the same time, when the laser cutting device for plastic products clamps the plastic products, the operator needs to manually rotate the bidirectional screw multiple times. When a large number of plastic products need to be cut, the operator needs to consume more physical strength, thereby increasing the manual labor. Utility Model Content

The swing of the vertical plate 15 drives the laser cutting gun 7 to move. The model of the laser cutting gun 7 can be selected according to the specific usage.

[0027] The vertical plate 15 is movably connected to the first frame 2 through a pin shaft, and a laser cutting gun 7 is installed at the end of the vertical plate 15.

[0029] Working principle:

[0030] When using a laser cutting device to cut plastic products:

[0031] Preparation process:

[0032] The operator first adjusts the angle of the laser cutting gun 7 according to the angle at which the plastic product needs to be cut, and starts the first multi-stage electric telescopic rod 501. The output end of the first multi-stage electric telescopic rod 501 moves, driving the slider 502 to slide along the outer wall of the second fixed column 503, thereby driving the cylinder 504 to slide along the slide groove processed on the oblique rod 505, and then driving the vertical plate 15 to swing along the connection point with the first frame 2. The swing of the vertical plate 15 drives the laser cutting gun 7 to move. When the laser cutting gun 7 moves to the angle at which the plastic product needs to be cut, the first multi-stage electric telescopic rod 501 is closed to achieve automatic adjustment of the angle of the laser cutting gun 7. Compared with manual adjustment by the operator, the time required is shorter, thereby improving work efficiency.

[0033] Plastic product limiting process:

[0034] The operator places the plastic product to be cut between the two limit plates 902, and then starts the second multi-stage electric telescopic rod 901. The output end of the second multi-stage electric telescopic rod 901 extends to drive the right limit plate 902 to move and slide to the left along the outer wall of the third fixed column 906, thereby driving the right connecting rod 903 to move. The movement of the right connecting rod 903 drives the rotating rod 904 to move, thereby driving the left connecting rod 903 and the limit plate 902 to move to the right. When the inner sides of the two limit plates 902 are tightly fitted with the plastic product, the second multi-stage electric telescopic rod 901 is closed to achieve that when limiting the plastic product, the operator does not need to manually adjust the clamping plates on both sides, and does not need to consume much physical strength of the operator, thereby saving labor to a certain extent.

[0035] Plastic product cutting process:

[0036] The power supply of the first motor 14 is started, and the output shaft of the first motor 14 rotates to drive the first threaded rod 3 to rotate, thereby driving the first frame 2 to slide along the outer wall of the first fixing column 4, thereby driving the laser cutting gun 7 to move forward and backward;

[0037] The power supply of the second motor 13 is started, and the output shaft of the second motor 13 rotates to drive the second threaded rod 10 to rotate, thereby driving the second frame 2 to slide along the outer wall of the fourth fixing column 8, thereby driving the plastic product to move left and right.

[0038] Then the operator can cut the plastic product according to the position where the plastic product needs to be cut by controlling the switches of the first motor 14, the second motor 13 and the laser cutting gun 7. After cutting, the operator controls the second multi-stage electric telescopic rod 901 to reset the limit plate 902, and then the operator can remove the cut plastic product. After cutting, the operator uses an external vacuum cleaner to clean the waste chips. The sliding door installed on the front side of the second frame 11 makes it convenient for the operator to clean the inside of the second frame 11.

[0039] While the present invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
