Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a waste material recovery structure for a plastic cutting machine. Background Art

[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material. Plastic products have the advantages of a wide range of raw materials, low production costs and strong plasticity. Plastic products need to be cut during the production process. Plastic products need to be processed on a cutting table using a cutting machine.

[0003] The patent document with the prior art publication number CN220481925U provides a waste material recovery component for a plastic product cutting table, comprising a cutting table and a cutter body, a hydraulic cylinder is fixedly installed on the left upper end of the cutting table, the free end of the hydraulic cylinder piston rod is fixedly connected to an L-shaped fixing seat, the cutter body is fixedly installed on the upper end of the horizontal section of the L-shaped fixing seat, and a transparent cover body is rotatably connected to the right upper end of the cutting table, a first opening is provided on the left inner wall of the transparent cover body, and a second opening is provided on the front inner wall of the transparent cover body; the waste material recovery component for a plastic product cutting table moves the cutter body into the transparent cover body after passing through the first opening, so that the fan can remove the cutter body. The cut waste is directly blown into a discharge port with an inverted trapezoidal cross section, and is introduced into an uncovered collecting trough through the discharge port, instead of blowing the material horizontally, avoiding the problem of unclean cleaning of the cutting table surface. The transparent cover is pulled by the handle and rotated in conjunction with the hinge, which is convenient for manual cleaning of the cutting table surface inside the transparent cover. Although the waste recovery component for the plastic product cutting table has good beneficial effects, the following problems still exist: the waste generated during plastic cutting is of different sizes, and the waste recovery component for the plastic product cutting table is difficult to treat wastes of different sizes in the same way, resulting in larger wastes occupying too much recycling space. In view of this, we propose a waste recovery structure for a plastic cutting machine. Utility Model Content

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0021] Example:

[0022] This embodiment discloses a waste material recovery structure for a plastic cutting machine, see Figures 1 to 3 , including a laser cutting machine 1, a guide mechanism 2 and a crushing and recovery mechanism 3; in this embodiment, the laser cutting machine 1 is an existing plastic cutting device on the market.

[0023] like Figures 1 to 3 As shown, the guide mechanism 2 is arranged at the bottom of the laser cutting machine 1.

[0024] Specifically, Figures 1 to 3As shown, the crushing and recycling mechanism 2 includes a square bin 201 with an open top, two symmetrically arranged placement plates 202, a motor A203 and a long shaft 204; the square bin 201 is arranged at the bottom of the laser cutting machine 1, and the opposite ends of the two placement plates 202 are rotatably connected to the two sides of the opening end of the square bin 201 through a rotating shaft, and the opposite ends of the two placement plates 202 are fixedly connected to a worm gear 205 through a rotating shaft, the motor A203 is fixedly installed on the outer wall of one side of the square bin 201 by screws, the long shaft 204 is arranged on the top of the motor A203, the long shaft 204 and the motor A203 are driven by a bevel gear set, and the long shaft 20 4 is rotatably connected with the outer wall of one side of the square bin 201 by installing bearings, and both ends of the long shaft 204 are fixedly connected with worms 206, which mesh with worm wheels 205; the two placement plates 202 are used to place the plastic to be cut. After the plastic is cut, the cut part is taken out, and the motor A203 is driven by the external control mechanism. The motor A203 drives the long shaft 204 to rotate through the bevel gear set, and the long shaft 204 drives the two worms 206, and the worms 206 drive the two worm wheels 205 to rotate, thereby driving the two placement plates 202 to rotate downward on the opposite side to form a guide cavity, so that the residual material slides to the crushing recovery mechanism 3.

[0025] Further, such as Figures 1 to 3 As shown, a chute 2011 is provided at one end of the top surface of one side of the square bin 201 relative to the two placement plates 202. The chute 2011 is in an arc shape with the rotation connection point of the placement plate 202 as the center. A slider 2021 is provided at the position of the placement plate 202 relative to the chute 2011. The slider 2021 is slidably connected to the chute 2011. The top of the chute 2011 and the rotation connection point of the placement plate 202 are maintained at the same horizontal height. The horizontal height of the bottom end of the chute 2011 is higher than the horizontal height of the top of the crushing bin 301. When the motor A203 rotates forward, it drives the slider 2021 at one end of the placement plate 202 to slide downward along the slide groove 2011. When the motor A203 rotates reversely, it drives the slider 2021 at one end of the placement plate 202 to slide upward along the slide groove 2011. At the same time, the slide groove 2011 has a limiting effect on the placement plate 202, preventing the placement plate 202 from rotating too much downward and causing the placement plate 202 to be damaged by the crushing and recycling mechanism 3, and at the same time preventing the placement plate 202 from flipping upward too much, which is inconvenient for the placement and cutting of the plastic.

[0026] like Figures 1 to 3 As shown, the crushing and recovery mechanism 3 is arranged inside the guide mechanism 2.

[0027] Specifically, Figures 1 to 3As shown, the crushing recovery mechanism 3 includes a crushing bin 301, a motor B302 and a rotating shaft 303; the crushing bin 301 is open at the top and bottom and is arranged at the bottom of the placement plate 202, the motor B302 is fixedly installed on the bottom outer wall of one side of the square bin 201 through the mounting plate, and the rotating shaft 303 is provided with two and is parallelly arranged in the square bin 201, the output end of the motor B302 is fixedly connected to one end of one of the rotating shafts 303, and the other ends of the two rotating shafts 303 are meshed and driven by a gear set, and the rotating shaft 303 is provided with a motor B302. 03 The surface fixed sleeve is provided with a crushing wheel 304, and the bottom of the crushing bin 301 is provided with a collecting bin 305. The residual material slides into the crushing bin 301, and the motor B302 is driven by the external control mechanism. The motor B302 drives one of the rotating shafts 303 to drive the other rotating shaft 303 to rotate opposite to its seat through the gear set, and then drives the crushing wheels 304 on the two rotating shafts 303 to rotate oppositely, so that all the residual materials of different sizes are crushed, and the crushed residual materials fall into the collecting bin 305 from the bottom of the crushing bin 301.

[0028] Further, if Figures 1 to 3 As shown, a through slot 2012 is provided at the bottom of the square bin 201, and one end of the collecting bin 305 is passed through the through slot 2012. The collecting bin 305 is pulled out from the bottom of the square bin 201 along the through slot 2012, so as to facilitate the recovery and cleaning of the broken plastic residues.

[0029] It is worth noting that if Figure 2 As shown, the bottom walls on both sides of the crushing bin 301 are inclined toward the middle of the collecting bin 305 , ensuring that the crushed residual materials fall accurately from the bottom of the crushing bin 301 into the collecting bin 305 .

[0030] Working principle: When the utility model is used, the plastic to be cut is first placed on the placement plate 202, and the laser cutting machine 1 is driven by an external control mechanism to cut the plastic. After cutting, the cut part is taken out by hand, and the motor A203 is driven by the external control mechanism. The motor A203 drives the long shaft 204 to rotate through the bevel gear set, and the long shaft 204 drives the two worms 206, and the worms 206 drive the two worm wheels 205 to rotate, thereby driving the two placement plates 202 to rotate one side downward, and at the same time drive the slider 2021 at one end of the placement plate 202 to slide downward along the slide 2011 until the slider 2021 is connected to the bottom of the slide 2011. The driving motor A203 is stopped, and the two placement plates 202 form a guide cavity at this time, so that the residual material slides into the crushing bin 301, and passes through The external control mechanism drives the motor B302, and the motor B302 drives one of the rotating shafts 303 to drive the other rotating shaft 303 to rotate opposite to its seat through the gear set, and then drives the crushing wheels 304 on the two rotating shafts 303 to rotate opposite to each other, so that all the residual materials of different sizes are crushed. The crushed residual materials fall into the collecting bin 305 from the bottom of the crushing bin 301, and are pulled out of the collecting bin 305 from the bottom of the square bin 201 along the through groove 2012, so as to facilitate the recycling and cleaning of the broken plastic residual materials. When cutting the plastic again, the motor A203 is driven in the reverse direction by the external control mechanism to drive the slider 2021 at one end of the placement plate 202 to slide upward along the slide groove 2011 until the slider 2021 is connected with the top of the slide groove 2011, so as to ensure that the two placement plates 202 are in a horizontal state.

[0031] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
