[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] The disclosure below provides many different embodiments or examples to implement the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0044] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0045] In order to solve the technical problem that the blade structure in the prior art has poor material cutting and crushing ability and material mixing ability, the present application provides a blade structure, a stirring assembly and a mixing equipment, which can cut the material at high speed through the cutting part 11 on the blade body 1. When the material moves along the guide part 12 of the blade body 1, the moving direction of the material can be changed by the first pushing part 2 and the second pushing part 3, so that the material can be mixed while moving along the guide part 12.

[0046] See also Figures 1 to 9 In a first aspect, the present application provides a blade structure, including a blade body 1, a first pusher 2, and a second pusher 3. The blade body 1 includes a cutting portion 11 and a flow guide 12 connected to each other, and the cutting portion 11 and the flow guide 12 are connected in an arc shape, such as Figure 2 , Figure 3 and Figure 4 As shown; the cutting portion 11 is located on the material-facing side of the blade body 1, which can improve the material cutting and crushing ability of the blade structure. When the blade structure rotates at high speed, the cutting portion 11 contacts the material before the guide portion 12. Since the cutting portion 11 has been sharpened, the cutting portion 11 is sharper, which can make it easier for the blade body 1 to cut into the material, and have a certain high-speed cutting effect on the material. While quickly reducing the particle size of the material, since the cutting portion 11 is sharper, the force area between the cutting portion 11 and the material is smaller, which can reduce the impact on the material during rotation.

[0047] The first pusher part 2 is arranged to protrude from the surface of the guide part 12, and the first pusher part 2 extends along the first direction. When the material moves along the surface of the guide part 12, the material in contact with the first pusher part 2 will move along the first direction under the pushing action of the first pusher part 2. The second pusher part 3 is arranged to protrude from the surface of the guide part 12, and the second pusher part 3 extends along the second direction. When the material moves along the surface of the guide part 12, the material in contact with the second pusher part 3 will move along the second direction under the action of the second pushing part. The first pusher part 2 and the second pusher part 3 are arranged opposite to each other, and the first direction and the second direction are arranged at an angle, then the material moves along the guide part 12 under the joint action of the first pusher part 2 and the second pusher part 3, and will be mixed at the intersection of the first direction and the second direction.

[0048] It should be noted that the cross section of the blade body 1 is in the shape of a volute or a tile. Figure 3 When the blade body 1 is unfolded into a flat plate structure, its shape can be a rectangular or trapezoidal structure, and the cutting portion 11 is a sharp structure arranged on one side of the rectangular or trapezoidal structure, which can achieve the purpose of the present application.

[0049] As a specific embodiment of the present application, when the blade body 1 is unfolded into a flat plate-like structure, its shape is a right-angled trapezoidal structure, and the cutting portion 11 is arranged at the hypotenuse of the right-angled trapezoidal structure, such as Figure 2 and Figure 4 As shown, it is beneficial to increase the length of the cutting portion 11 , thereby expanding the material cutting range of the blade body 1 .

[0050] In some embodiments of this application, please refer to Figure 3 The cutting portion 11 has a triangular cross section, and the tool tip angle in the triangular cross section is α. Figure 3 Preferably, the value range of α is 5°-20°. This is because when the blade tip angle of the cutting portion 11 is less than 5°, the blade tip is thin and is easily damaged due to insufficient structural strength when cutting materials at high speed. When the blade tip angle is greater than 20°, the blade tip of the cutting portion 11 is too blunt and the cutting effect is poor.

[0051] It should be noted that the first pusher 2 and the second pusher 3 are arranged on the same side surface of the guide 12, specifically, the inner surface and / or the outer surface of the guide 12. The number of the first pusher 2 and the second pusher 3 can be one or more, and the multiple first pusher 2 and the multiple second pusher 3 can be arranged in partitions or staggered at intervals, which can achieve the purpose of the present application.

[0052] As a specific embodiment of the present application, the first pusher 2 and the second pusher 3 are both arranged on the outer surface of the guide 12. This is because under the action of centrifugal force, most of the materials will move along the outer surface of the guide 12. Multiple first pushers 2 are arranged in parallel in the rear area of ​​the blade body 1, and the first direction is inclined forward, so as to push the materials to the front area of ​​the blade body 1; multiple second pushers 3 are arranged in parallel in the front area of ​​the blade body 1, and the second direction is inclined backward, so as to push the materials to the rear area of ​​the blade body 1, so that the materials are mixed in the middle area of ​​the blade body 1, such as Figure 6 shown.

[0053] In some embodiments of this application, please refer to Figure 6 , the angle between the first direction and the rotation axis of the blade structure is β, and the angle between the second direction and the rotation axis of the blade structure is γ. In order to enable the first pusher 2 to push the material in the positive axial direction and the second pusher 3 to push the material in the reverse axial direction, the preferred value range of β is 60°-80°, and the value range of γ is 100°-120°. This is because when the value of β is greater than 80° and the value of γ is less than 100°, the first pusher 2 and the second pusher 3 are easy to reach a state close to parallel, and the axial pushing effect on the material is small, and the mixing effect of the material in the axial direction is poor. When the value of β is less than 60° and the value of γ is greater than 120°, when the material moves in the radial direction (i.e., in the direction perpendicular to the axial direction) along the guide portion 12, it will be blocked by the first pusher 2 and the second pusher 3, resulting in the blade structure as a whole being subjected to excessive rotational resistance (i.e., reaction force) exerted by the material.

[0054] In the above embodiments, the first pushing portion 2 and the second pushing portion 3 are rib structures or rib structures protruding from the surface of the guide portion 12, both of which can achieve the purpose of the present application.

[0055] In some embodiments of the present application, the first pusher 2 and the second pusher 3 are plate-like structures, which are spirally arranged on the outer side of the guide portion 12, and the spiral directions of the first pusher 2 and the second pusher 3 are opposite. Figure 4 and Figure 6 shown.

[0056] In some embodiments of this application, please refer to Figure 4 The first push part 2 and the second push part 3 are both provided with a blade-shaped portion, and the blade-shaped portion is arranged close to the cutting portion 11. By sharpening the blade-shaped portion, the blade-shaped portion can be made sharper, which is convenient for the first push part 2 or the second push part 3 to cut into the material, and the material is cut twice by the blade-shaped portion, thereby further improving the cutting effect of the paddle structure on the material. At the same time, since the contact area between the blade-shaped portion and the material is small, the impact of the material on the first push part 2 and the second push part 3 can also be reduced.

[0057] Specifically, the starting end of the first pusher 2 (i.e., the end close to the cutting part 11) has a first blade 21, and the starting end of the second pusher 3 has a second blade 31. The material passes through the cutting part 11 and the blade in sequence, and at least two consecutive cuts can be achieved, which is conducive to achieving uniform mixing of the material. It can also reduce the impact of the material on the blade structure, so that the mixing equipment can operate stably.

[0058] It should be noted that the cross-sections of the first blade-shaped portion 21 and the second blade-shaped portion 31 are also triangular cross-sections, and the blade tip angles thereof are also preferably 5°-20°.

[0059] The second aspect of the embodiment of the present application provides a stirring assembly, including the paddle structure in the above embodiment, and also includes a transmission member 4, on which a plurality of paddle structures are provided, and the plurality of paddle structures are centrally symmetrically distributed with the rotation center of the transmission member 4 as the center; when the transmission member 4 rotates at high speed, the plurality of paddle structures can be driven to operate synchronously at high speed.

[0060] The first pusher 2 and the second pusher 3 on the paddle structure are sequentially arranged along the axial direction of the transmission member 4. Figure 6 As shown, when the transmission member 4 drives the blade structure to rotate, the material can not only move radially under the action of centrifugal force, but also be mixed along the axial direction of the transmission member 4 under the joint action of the first pushing part 2 and the second pushing part 3.

[0061] In some embodiments of this application, please refer to Figure 2 , Figure 4 and Figure 5 There is a first preset distance between the cutting portion 11 and the rotation center of the transmission member 4, and there is a second preset distance between the guide portion 12 and the rotation center of the transmission member 4. The first preset distance is smaller than the second preset distance, that is, the cutting portion 11 and the guide portion 12 are in different radial positions. When the material passes through the cutting portion 11 and the guide portion 12 in sequence, it can move in the radial direction. Combined with the axial function of the first pushing portion 2 and the second pushing portion 3, the material can be mixed in both the radial and axial directions, which is beneficial to improving the mixing degree of the material.

[0062] In some embodiments of the present application, the transmission member 4 includes a coaxially arranged shaft portion 41 and a disc portion 42, and a plurality of blade structures are centrally symmetrically distributed with the center of the disc portion 42 as the center. When the plurality of blade structures rotate, the transmission member 4 can be subjected to balanced forces to avoid the transmission member 4 from swinging. The blade structure, the shaft portion 41, and the disc portion 42 are an integrated structure, which can be prepared by integral casting and then fine machining the cutting portion 11 and the blade portion, which is conducive to improving the connection reliability between the transmission member 4 and the blade structure.

[0063] It should be noted that the above stirring assembly can be applied to both ordinary mixing equipment and mixing equipment for raw materials including plastics, rubber and other materials. When materials such as plastics come into contact with the high-speed rotating blade structure, they will melt due to the high-speed friction with the blade structure, thereby achieving mixing with other materials such as straw fragments. However, under the action of centrifugal force, the melted plastic will wrap the straw fragments and adhere to the inner wall of the mixing equipment. The material can only move along the inner wall of the mixing chamber 5. Figure 5 The paddle structure cannot further cut and mix the mixed material, resulting in poor mixing effect, such as Figure 5 shown.

[0064] In order to solve the above problems, the third aspect of the embodiment of the present application provides a mixing device, including the stirring assembly in the above embodiment, and also including a mixing chamber 5, the mixing chamber 5 includes a plurality of mixing cavities, and the plurality of stirring assemblies are arranged in a one-to-one correspondence with the plurality of mixing cavities, such as Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the dotted arrow is the moving direction of the material in the mixing chamber 5. Two adjacent mixing chambers are connected, and the two stirring components in the two adjacent mixing chambers rotate in opposite directions. Driven by the stirring components, the plastic and straw fragments will move radially between the two adjacent mixing chambers, from one mixing chamber to another, and reciprocate to avoid the material from being attached to the inner wall of the mixing chamber 5 for a long time, increase the contact frequency between the material and the blade structure, and achieve efficient cutting and mixing.

[0065] Specifically, the plurality of transmission members 4 are rotatably disposed on the back plate 58 of the mixing chamber 5. Figure 4 The number of mixing chambers can be more than 2. When the mixing chamber 5 includes the first mixing chamber 51 and the second mixing chamber 52, the rotation direction of one stirring component is left-handed and the rotation direction of the other stirring component is right-handed. The material moves in an 8-shaped pattern between the first mixing chamber and the second mixing chamber. Figure 7 shown.

[0066] When the mixing chamber 5 includes the first mixing cavity 51, the second mixing cavity 52 and the third mixing cavity 53, the three mixing cavities can be arranged side by side, and the stirring components in two adjacent mixing cavities rotate in opposite directions, such as Figure 8 The three mixing chambers can also be arranged in an L shape, and the stirring components in two adjacent mixing chambers rotate in opposite directions, as shown in FIG. Fig. 9 As shown, radial movement of materials between any two adjacent mixing chambers can be achieved.

[0067] In some embodiments of this application, please refer to Figure 7The inner sides of the multiple blade structures are enclosed to form a material storage space, the mixing space is formed between the inner wall of the mixing cavity and the outer side of the blade structure, and a radial flow channel for connecting the material storage space and the mixing space is formed between two adjacent blade structures. When the material enters the mixing cavity, it first enters the material storage space. During the rotation of the stirring component, the material in the material storage space flows out through the radial flow channel, and collides with the blade structure during the outflow process, so that the cutting part 11, the blade-shaped part and other structures cut the straw, plastic and other materials at a high speed, and the plastic melts when it rubs against the cutting part 11 and the guide part 12, so that the melted plastic and the cut straw fragments are evenly mixed in the mixing space.

[0068] In some embodiments of the present application, the mixing spaces in two adjacent mixing chambers are connected to form an 8-shaped structure, so that the melted plastic and the cut straw fragments can move in an 8-shaped structure in the adjacent mixing spaces, so that the materials fly out of the mixing space on one side and enter the mixing space on the other side under the action of centrifugal force, thereby causing radial mixing of the materials.

[0069] In some embodiments of this application, please refer to Figure 1 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 The kneading chamber 5 includes a feed port 54 and a discharge port 55. The feed port 54 is connected to the material storage space, so that the material enters the material storage space, and moves radially under the drive of the stirring assembly to cut and mix the material. The discharge port 55 is connected to the kneading space, so that the mixed material can be discharged from the kneading chamber 5.

[0070] In order to avoid the situation of material back spraying, the mixing chamber 5 also includes a feed door 56 and a discharge door 57. Figure 1 As shown, the feed door 56 is movably arranged at the feed port 54, and the discharge door 57 is movably arranged at the discharge port 55, and can be opened and closed as needed. When materials are mixed inside the mixing chamber 5, the feed door 56 and the discharge door 57 are both in a closed state to avoid material back spraying or material leakage.

[0071] It should be noted that the feed port 54 is arranged at the front end of the paddle structure, and multiple mixing chambers can share one feed port 54, or can be provided with mutually independent feed ports 54, and both can achieve the purpose of the present application. When each mixing chamber corresponds to one feed port 54, the feed port 54 is located at the center of the mixing chamber, and is arranged opposite to the material storage space. At this time, the opening cross-sectional size of the feed port 54 is preferably smaller than the minimum cross-sectional size of the mixing space, and the material back-spraying path in the mixing space is blocked by the inner wall surface of the feed port 54, so that even when adding materials, the material in the mixing space can be prevented from back-spraying and leaking from the feed port 54.

[0072] The discharge port 55 is arranged at the bottom of the mixing chamber, so that the material can be discharged under the action of gravity. Preferably, each mixing chamber is provided with a corresponding discharge port 55 to avoid material residue in the mixing chamber 5. Fig. 9 When two adjacent mixing chambers are connected up and down, the two mixing chambers are connected at the discharge port 55 of the upper mixing chamber.

[0073] In the above embodiment, the volume of the mixing space can be designed to be 1-2 times the volume of the molten material. This is because, when the volume of the mixing space is greater than 2 times the volume of the molten material, on the one hand, the volume of the mixing chamber 5 will be too large, and on the other hand, when the molten material adheres to the inner wall of the mixing chamber 5, the distance between the molten material and the paddle structure is too large, and it cannot contact the paddle structure. The volume of the storage space is about 1-3 times the volume of the initial granular material (i.e., unreacted material). This is because, when the volume of the storage space is greater than 3 times the volume of the initial granular material, the distance between the paddle structures will be too large, resulting in a larger rotor structure and mass formed by the transmission member 4 and the paddle structure, which will increase the power of the mixing equipment.

[0074] In some embodiments of this application, please refer to Figure 1 and Figure 2 The mixing device also includes a driving assembly 6, which is connected to the transmission member 4 and is used to drive the transmission member 4 and the blade structure to rotate at a high speed.

[0075] In some embodiments of the present application, the driving assembly 6 includes a driving motor 61, a belt transmission assembly 62 and a transmission box 63. The driving motor 61 transmits power to the belt transmission assembly 62 and the transmission box 63. The transmission box 63 is provided with multiple output shafts for connecting one-to-one with multiple transmission members 4, thereby realizing the reverse rotation of two adjacent stirring assemblies.

[0076] In some embodiments of this application, please refer to Figure 1 and Figure 2 The mixing device also includes a base 7, on which the driving assembly 6 and the mixing chamber 5 are both arranged, so that the mixing device is connected into a whole, which is convenient for overall movement and layout as needed.

[0077] See also Figures 1 to 9 In some embodiments of the present application, the method of using the above mixing equipment is as follows:

[0078] Step 1: With the discharge door 57 closed, open the feed door 56, add plastic (granules or powder) and straw fragments into the mixing chamber 5, and then close the feed door 56;

[0079] Step 2: Start the driving assembly 6, so that the multiple stirring assemblies rotate at a high speed, and the material also moves at a high speed; the cutting part 11 and the blade part cut the material at a high speed, the straw fragments become smaller, and there is intense friction between the plastic and the blade structure, thereby generating a large amount of heat in a very short time, so that the plastic is completely melted within 20 to 50 seconds;

[0080] Step 3: The materials are mixed along the axial direction under the action of the first pushing part 2 and the second pushing part 3, move radially under the action of centrifugal force, and move in an 8-shaped shape between two adjacent mixing chambers, so that the straw fragments and the molten plastic are evenly mixed;

[0081] Step 4: close the driving assembly 6 , open the discharge door 57 , and discharge the mixed material from the discharge port 55 .
