[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0027] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. If "first" or "second" is used in the description, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] In some embodiments of this utility model, such as Figures 1 to 3 As shown, the shredding device includes a housing 1 and a shredding assembly 3. The housing 1 has a shredding chamber 14. The shredding assembly 3 includes a rotating shaft 31, a plurality of first cutters 32, and a plurality of second cutters 33. The rotating shaft 31 is rotatably connected to the housing 1 and located within the shredding chamber 14. The plurality of first cutters 32 are spaced apart along the axial direction of the rotating shaft 31, and the plurality of second cutters 33 are spaced apart along the axial direction of the rotating shaft 31 on the inner wall of the shredding chamber 14, with the second cutters 33 inclined downwards. The first cutters 32 and second cutters 33 are arranged alternately.

[0031] In this example, a rotating shaft 31 is rotatably mounted within the inner cavity, and a first cutter 32 is mounted on the rotating shaft 31. Multiple first cutters 32 are spaced apart axially along the rotating shaft 31, that is, spaced apart vertically. The rotating shaft 31 can drive the multiple first cutters 32 to rotate. A second cutter 33 is fixedly connected to the inner wall of the crushing chamber 14. Multiple second cutters 33 are also spaced apart axially along the rotating shaft 31, that is, spaced apart vertically. The alternating arrangement of the first cutters 32 and the second cutters 33 in the vertical direction allows for improved crushing of the plastic through their mutual cooperation, thereby shortening the crushing time.

[0032] It should be noted that the inner wall of the crushing chamber 14 can be a cylindrical sidewall, and the rotating shaft 31 is arranged along the axis of the crushing chamber 14. The end of the first cutter 32 facing the second cutter 33 can be flush with the second cutter 33 in the vertical direction, so as to facilitate the removal of the rotating shaft 31 with the first cutter 32 installed from the crushing chamber 14.

[0033] It should also be noted that the second cutter 33 is inclined downwards, meaning that one end of the second cutter 33 is connected to the inner wall of the crushing chamber 14, and the other end extends downwards. This allows the plastic accumulated on the upper surface of the second cutter 33 to slide downwards under the influence of gravity, thus preventing plastic from accumulating on the upper surface of the second cutter 33 and facilitating material discharge.

[0034] like Figure 1 As shown, in this example, the crushing device further includes a drive assembly 5, which is connected to the rotating shaft 31 and can drive the rotating shaft 31 to rotate. The drive assembly 5 can be installed on the upper end of the housing 1. The drive assembly 5 may include a rotary motor and a gearbox, and the rotary motor can be connected to the rotating shaft 31 via the gearbox. Of course, the specific structure of the drive assembly 5 can be determined by those skilled in the art according to the actual situation, and is not specifically limited here.

[0035] like Figure 1 As shown, in this example, the shredder also includes a bracket 6 and casters 2. The housing 1 is mounted on the bracket 6, which supports the housing 1. The casters 2 are mounted on the bracket 6, allowing the shredder to be moved relatively easily.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the angle between the second cutter 33 and the inner wall of the crushing chamber 14 is 30° to 60°.

[0037] In this example, the second cutter 33 is inclined downwards, and the angle between the lower surface of the second cutter 33 and the inner wall of the crushing chamber 14 can be 30°, 40°, 45°, 50° or 60°, etc. Those skilled in the art can determine it according to the actual situation, and no specific limitation is made here.

[0038] It should be noted that the angle between each second cutter 33 and the inner wall of the crushing chamber 14 may be the same or different. Those skilled in the art can determine this according to the actual situation, and no specific limitation is made here.

[0039] like Figure 2 As shown, in some embodiments of the present invention, the first tool 32 includes a plurality of first blades, which are spaced apart circumferentially along the rotation axis 31.

[0040] In this example, each first cutter 32 may include multiple first blades, which are spaced apart circumferentially along the rotation axis 31. For example, the multiple first blades may be evenly spaced along the circumferential interval of the rotation axis 31. This increases the blade density, thereby improving the material crushing effect.

[0041] It should be noted that each first tool 32 may be equipped with two, three or four first blades, which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0042] It should also be noted that the cutting edge of the first blade can be an arc-shaped structure or a linear structure, which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0043] In some embodiments of the present invention, the second cutter 33 includes a plurality of second blades, which are spaced apart circumferentially along the crushing chamber 14.

[0044] In this example, each second cutter 33 may include multiple second blades, which are fixedly mounted on the inner wall of the crushing chamber 14 and spaced apart along the inner wall of the crushing chamber 14. For example, each second cutter 33 may include two, three, or four second blades, which can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0045] It should be noted that the number of second blades included in each second tool 33 may be the same or different, and those skilled in the art can determine it according to the actual situation, without making specific limitations here.

[0046] It should also be noted that, in the vertical direction, the second blades of each second cutter 33 can be staggered, which is beneficial to further improve the crushing effect.

[0047] like Figure 3As shown, in some embodiments of this utility model, the inner wall of the crushing chamber 14 is provided with a positioning groove 11, and the second blade can be partially embedded in the positioning groove 11.

[0048] In this example, the inner wall of the crushing chamber 14 is provided with a positioning groove 11 for positioning the second blade. That is, one end of the second blade can be inserted into the positioning groove 11 first, and then the second blade can be fixed, which improves the ease of assembling the second blade. For example, the second blade can be fixed to the inner wall of the crushing chamber 14 by fasteners such as screws.

[0049] like Figure 3 As shown, it should be noted that the positioning groove 11 is also inclined downwards, and the same as the inclination angle of the second blade, so that after the second blade is inserted into the positioning groove 11, the angle between the second blade and the inner wall of the crushing chamber 14 is a preset angle.

[0050] In some embodiments of this utility model, multiple positioning grooves 11 are provided. That is, the inclination angle of each group of positioning grooves 11 is different, so that after the second blade is inserted into different positioning grooves 11, the angle between the second blade and the inner wall of the crushing chamber 14 is different, which helps to improve the applicability of the second blade.

[0051] In some embodiments of this utility model, the second cutting tool 33 is integrally formed with the housing 1. That is, during processing, the housing 1 has the second cutting tool 33 integrally formed on the inner wall of the crushing chamber 14.

[0052] Of course, the second cutter 33 can also be fixedly connected to the inner wall of the crushing chamber 14 by means of fasteners or welding. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0053] In some embodiments of this utility model, the crushing device further includes a vibrator that can act on the housing 1.

[0054] In this example, after the material is crushed, the vibrator can be activated. The vibrator vibrates and acts on the housing 1, causing the housing 1 to vibrate. This allows the crushed particles adhering to the inner wall of the crushing chamber 14 and the surface of the cutter to detach from the inner wall of the crushing chamber 14 and the surface of the cutter, and fall downwards to the discharge port 13. This reduces the amount of crushed particles adhering to the inner wall of the crushing chamber 14 and the surface of the cutter, thus reducing waste.

[0055] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, the crushing device further includes a discharge pipe 4, and the bottom wall 12 of the crushing chamber 14 is provided with a discharge port 13, and the discharge pipe 4 is connected to the discharge port 13.

[0056] In this example, the bottom wall 12 of the crushing chamber 14 is provided with a discharge port 13. One end of the discharge pipe 4 is connected to the discharge port 13, and the other end extends outward to facilitate the discharge of crushed particles. The discharge pipe 4 can be configured as an arc-shaped structure or a bent design, so that the crushed particles can be guided to a preset position through the discharge pipe 4, thereby improving the convenience of discharge.

[0057] like Figure 2 As shown, in some embodiments of this utility model, the bottom wall 12 is inclined, and the discharge port 13 is located at the lower part of the bottom wall 12.

[0058] like Figure 2 As shown, in this example, the bottom wall 12 gradually slopes downwards from the side to the middle, that is, the side is higher and the middle is lower, with the discharge port 13 located at the lower part to facilitate material discharge. Alternatively, the bottom wall 12 can also be arranged to gradually slope downwards from one side to the other, with the higher side being higher and the lower side being lower. The specific design of the bottom wall 12 can be determined by those skilled in the art based on actual circumstances, and is not specifically limited here.

[0059] like Figure 2 As shown, in some embodiments of this utility model, the crushing device further includes a filter screen 7, which is disposed above the discharge port 13 and below the rotating shaft 31. The plastic is crushed above the filter screen 7 by a first blade 32 and a second blade 33. Once the plastic particles are crushed to a preset outer diameter, they can pass through the filter screen 7 and flow out from the discharge port 13. Different filter screens 7 can be used when different outer diameter plastic particles are required.

[0060] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0061] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
