[0016] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0017] like Figure 1-Figure 8 A laser cutting device for producing injection molded products shown in the figure comprises a processing table 1, a fixed seat 2 is fixedly installed at the rear of the upper surface of the processing table 1, a sliding seat 6 is connected to the front surface of the fixed seat 2 through a traveling mechanism, and movable plates 9 are connected to the upper surface of the sliding seat 6 on both sides through distance adjustment mechanisms, and the front end of the movable plate 9 is fixedly connected to a limiting column 12, and a lifting plate 16 is inserted on the front surface of the limiting column 12 through a lifting mechanism, and limiting balls 17 are fixedly connected to the adjacent corners of the lifting plates 16 on both sides, and a bridge 18 is fixedly sleeved on the outer side of the processing table 1, and a transverse slide 19 is installed on the inner side of the bridge 18 through a transverse and longitudinal servo mechanism, and a laser cutting head 20 is fixedly installed on the front surface of the transverse slide 19. The laser cutting head 20 is a prior art, but it is not repeated in detail, and a folding rod 21 is fixedly connected to one side of the front surface of the transverse slide 19, and an inclined guide plate 22 is fixedly connected to the lower end of the folding rod 21; The plastic barrel 31 is placed on the upper surface of the processing table 1 , the lower end of the plastic barrel 31 contacts the limiting columns 12 on both sides, and the outer surface of the plastic barrel 31 contacts the two limiting balls 17 .

[0018] like Figure 2 , Figure 3 As shown, the traveling mechanism includes a telescopic cylinder 3 and a guide cylinder 4 fixedly connected to the front surface of the fixed seat 2, a guide column 5 is slidably inserted into the front end of the guide cylinder 4, and the front end of the guide column 5 and the telescopic end of the telescopic cylinder 3 are respectively fixedly connected to the rear surface of the sliding seat 6. When the telescopic cylinder 3 is extended and retracted, the guide column 5 will slide along the inner side of the guide cylinder 4 to improve the stability of the sliding seat 6 when it moves.

[0019] The distance adjustment mechanism includes a transverse cylinder 7 fixedly mounted on the upper surface of the sliding seat 6 through a mounting plate 8, an enlarged plate 10 is fixedly connected to the rear end of the moving plate 9, and the telescopic end of the transverse cylinder 7 is fixedly connected to the side surface of the enlarged plate 10. The side surface area of ​​the enlarged plate 10 is large, which is convenient for the fixed installation of the telescopic end of the transverse cylinder 7. A sliding hook 11 is fixedly connected to the lower surface of the moving plate 9, and the sliding hook 11 is slidably sleeved on the front upper side of the sliding seat 6. The sliding hook 11 plays a role of limiting, preventing the transverse cylinder 7 from being deformed and damaged by the force acting toward the rear when the plastic barrel 31 pushes the limiting column 12.

[0020] like Figure 4 As shown, the lifting mechanism includes a slide groove 13 provided on the front surface of the limiting column 12, a lifting plate 16 is slidably inserted into the inner side of the slide groove 13, a threaded rod 14 is rotatably connected to the inner side of the slide groove 13, and the upper end of the threaded rod 14 passes through the upper surface of the limiting column 12 and is fixedly installed with a polygonal head 15. The polygonal head 15 is convenient for the user to rotate the threaded rod 14 with the help of a wrench.

[0021] like Figure 6 As shown, the horizontal and vertical servo mechanism includes a vertical slide 26 slidably mounted on the inner wall of the bridge 18 on both sides through the Y-axis servo mechanism, a horizontal guide rod 24 is fixedly mounted between the vertical slides 26 on both sides, and the horizontal guide rod 24 slides through the inner side of the horizontal slide 19, and a horizontal screw rod 23 is rotatably connected between the vertical slides 26 on both sides and near the upper part of the horizontal guide rod 24, and the horizontal screw rod 23 threads through the inner side of the horizontal slide 19, and a first motor 25 is fixedly mounted on the front surface of one of the vertical slides 26, and the output shaft of the first motor 25 is fixedly connected to one end of the horizontal screw rod 23. When the first motor 25 drives the horizontal screw rod 23 to rotate, the horizontal slide 19 will move horizontally, and the horizontal guide rod 24 plays a role in guiding the horizontal slide 19 to move horizontally.

[0022] The Y-axis servo mechanism includes a vertical screw rod 27 rotatably mounted on one side of the top surface of the bridge 18, the vertical screw rod 27 is threaded through the inner side of the vertical slide 26 on one side, and the lower end of the vertical screw rod 27 is fixedly connected to the output shaft of the second motor 29, and the second motor 29 is fixedly mounted on the inner wall of the bridge 18. When the second motor 29 is running, the vertical screw rod 27 is rotated, thereby causing the vertical slide 26 to move up and down.

[0023] A vertical guide rod 28 is fixedly installed on the inner side of the bridge 18 and away from the side of the vertical screw rod 27, and the vertical guide rod 28 slides through the inner side of the vertical slide 26. The vertical guide rod 28 is provided to improve the stability of the vertical slide 26 on this side when it moves up and down.

[0024] like Figure 1 As shown, the bottom corners of the processing table 1 are fixedly mounted with feet 30. Obviously, the bottom surface of the feet 30 is flush with the bottom surface of the bridge 18, which improves the stability of the whole when placed.

[0025] The user places the plastic barrel 31 on the surface of the processing table 1, and the lower end of the plastic barrel 31 contacts the two limiting columns 12 to be positioned, and the surface of the plastic barrel 31 contacts the two limiting balls 17 to be positioned. Since there are four points between the lower end of the plastic barrel 31 and the surface position to be positioned, the problem of the plastic barrel 31 tipping over is not likely to occur during the positioning process, and the accurate positioning of the plastic barrel 31 can be guaranteed. The state after the arrangement is as follows Figure 7 , Figure 8 As shown; before placing a batch of plastic barrels 31 each time, the sliding seat 6 can be moved forward and backward by controlling the telescopic cylinder 3 to extend and retract, so as to change the front and rear position of the plastic barrel 31 after positioning, so as to cooperate with the subsequent laser cutting action, and the spacing between the limit columns 12 on both sides is changed by controlling the transverse cylinder 7 to extend and retract, so that the limit columns 12 on both sides are close to the positions of the two sides of the plastic barrel 31 during positioning, so as to ensure the stability after positioning, and the threaded rod 14 is rotated by rotating the polygonal head 15, so as to make the lifting plate 16 slide up and down along the inner side of the slide groove 13, so as to ensure that when the bottom of the plastic barrel 31 contacts the surface of the limit column 12, the limit ball 17 can contact the surface of the plastic barrel 31, so as to adapt to the different truncated cone shapes of the plastic barrel 31 for positioning, and the adaptability is good, and the rapid arrangement and positioning of the plastic barrel 31 can be completed.

[0026] Through the operation of the first motor 25, the transverse screw rod 23 rotates, driving the transverse slide 19 to translate, and the laser cutting head 20 cuts the gate 32. As the horizontal movement continues, the inclined guide plate 22 passes over the top of the plastic barrel 31, and the inclined guide plate 22 pushes the cut gate 32 to move forward, and then slides toward the front and bottom along the surface of the plastic barrel 31. Therefore, the purpose of cutting and quickly cleaning the gate 32 can be achieved.
