Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0041] Please see Figures 1-8 A plastic crusher for easy material feeding, including a frame 1, and further including:

[0042] Device box 2 is mounted on frame 1. Device box 2 includes a first box body 201 and a second box body 202, and the bottom of the second box body 202 is detachably connected to the top of the first box body 201 by bolts. The top of the second box body 202 has a vertical cavity 2021 and an inclined cavity 2022. The top of the vertical cavity 2021 is provided with a first top plate 6, and the top of the inclined cavity 2022 is provided with a second top plate 7. The first top plate 6 has a feed hole 601. The vertical cavity 2021 corresponds to the interior of the first box body 201, while the inclined cavity 2022 is inclined and offset. The inclined cavity 2022 can be used to insert large pieces of plastic, while the vertical cavity 2021 can be used to insert tubular or rod-shaped plastic. In addition, the first top plate 6 and the second top plate 7 are detachably connected to the top of the second box body 202 for easy maintenance.

[0043] The crushing component 3 is located inside the first housing 201;

[0044] Drive assembly 4 is mounted on frame 1 and is used to drive crushing assembly 3 to crush plastic;

[0045] Screen 5, located at the bottom of the first chamber 201, is used to screen the crushed plastic particles; through Figure 4 As can be seen, the bottom of the first box 201 is an open structure, and the screen 5 is installed at the bottom opening of the first box 201, so that the crushed plastic particles all fall through the screen 5; the side of the screen 5 is detachably connected to the bottom of the first box 201 by bolts, which facilitates the replacement of different screens 5 and the daily maintenance and cleaning of the screen 5.

[0046] And a stabilizing guide component 8, which is disposed on the top of the first top plate 6 and corresponds to and cooperates with the feed hole 601.

[0047] Furthermore, the stabilizing guide assembly 8 includes a first fixing ring 801 and a second fixing ring 802 fixed on the top of the first top plate 6 and located outside the feed hole 601. The first fixing ring 801 is located outside the second fixing ring 802, and the ring walls of the first fixing ring 801 and the second fixing ring 802 are provided with a plurality of through holes 803 at equal intervals along their respective circumferential directions. A straight rack 804 is provided inside the through hole 803, and a clamping member 806 is provided at one end of the straight rack 804 located inside the second connecting ring. An electric telescopic rod 805 is also installed on the top of the first top plate 6, and the output end of the electric telescopic rod 805 is connected to the end of one of the straight racks 804 away from the clamping member 806.

[0048] Furthermore, an annular rack 807 located below the straight rack 804 is slidably disposed on the inner side wall of the first fixed ring 801; a plurality of gears 808 are rotatably connected at equal intervals along the circumferential direction of the first fixed ring 801 on the top of the first top plate 6, and the gears 808 mesh synchronously with the annular rack 807 and the straight rack 804.

[0049] In summary, during use, by inserting the tubular plastic rod into the device housing 2 through the feed hole 601, the feed hole 601 corresponds to the vertical cavity 2021, and the vertical cavity 2021 is directly aligned with the interior of the first housing 201. This results in the tubular plastic rod entering the first housing 201 through the feed hole 601 being crushed in a vertical position. To improve the stability of the tubular plastic rod at this time, the stabilizing guide component 8 can effectively clamp and guide the part of the tubular plastic rod near the tail end, thereby preventing the tail end of the tubular plastic rod from swinging violently during crushing and affecting the overall crushing effect, resulting in better performance.

[0050] Furthermore, the clamping member 806 includes a connecting plate 8061 fixed to the end of the straight rack 804, and a slide rod 8062 is provided through the connecting plate 8061. A ball bearing 8063 is connected to one end of the slide rod 8062 away from the straight rack 804, and a spring 8064 is provided between the ball bearing 8063 and the connecting plate 8061.

[0051] Specifically, when in use, the stabilizing guide assembly 8 can move the other connected straight racks 804 by activating the electric telescopic rod 805, thereby moving the clamping members 806 on them. When the straight racks 804 move, they can drive the gears 808 to rotate. The gears 808 mesh with the annular rack 807, thereby causing the annular rack 807 to slide circumferentially on the inner side wall of the first fixed ring 801. The sliding of the annular rack 807 causes the other gears 808 to rotate, thereby allowing the other straight racks 804 to move their respective clamping members 806. In other words, all the clamping members 806 can be brought closer or further apart by using one electric telescopic rod 805, which facilitates the clamping of tubular plastic rods.

[0052] Meanwhile, during clamping, the ball bearing 8063 contacts the tubular plastic, allowing it to move up and down for continuous crushing. The spring 8064 also provides a clearance function for the ball bearing 8063, preventing uneven diameters at the ends of the tubular plastic. To prevent vibration during the clearance of the spring 8064, a damping rod compatible with the spring 8064 should be provided between the ball bearing 8063 and the connecting plate 8061. Alternatively, the slide bar 8062 can be replaced with a damping rod to improve the buffering and shock absorption effect.

[0053] In addition, it is worth mentioning that the outer surface of the ball bearing 8063 is smooth. The design of multiple ball bearings 8063 is only to facilitate the clamping and guiding of the tubular plastic and to prevent the tail end of the tubular plastic from swinging too much. The clamping force of the ball bearing 8063 will not affect the normal descent of the tubular plastic.

[0054] Furthermore, both the upper and lower ends of the through holes 803 inside the first fixing ring 801 and the second fixing ring 802 are provided with sliding grooves 809, and both the upper and lower ends of the straight rack 804 are fixed with sliders 810 located inside the sliding grooves 809; through the sliding cooperation between the sliders 810 and the sliding grooves 809, the movement path of the straight rack 804 is made more stable, thereby improving the overall performance of the stable guide assembly 8.

[0055] Furthermore, the crushing assembly 3 includes a rotating shaft 301 that extends laterally through the first housing 201, and the rotating shaft 301 is rotatably connected to the frame 1 via a bearing seat. A movable blade 302 located inside the first housing 201 is provided on the rotating shaft 301. An mounting plate 303 is fixed on the inner side wall of the first housing 201, and a fixed blade 304 that cooperates with the movable blade 302 is detachably connected to the top of the mounting plate 303.

[0056] Furthermore, the drive assembly 4 includes a motor 401 mounted on the frame 1, and the output end of the motor 401 is connected to a first transmission wheel 402, the end of the rotating shaft 301 is connected to a second transmission wheel 403, and the second transmission wheel 403 is connected to the first transmission wheel 402 by a transmission belt 404.

[0057] After the motor 401 drives the rotating shaft 301 to rotate, the moving blade 302 rotates at high speed. During the high-speed rotation of the moving blade 302, it tends to move relative to the fixed blade 304, and the gap formed between the moving blade 302 and the fixed blade 304 creates a cutting edge for crushing and shearing the plastic, thereby breaking down large pieces of plastic. At the same time, both the fixed blade 304 and the moving blade 302 are alloy steel blades, with sharp blades that are easy to replace and durable; the bearing housing adopts a double-layer seal, which ensures that the bearing rotation remains good for a long time.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
