[0001] The present application relates to the technical field of modified materials, and in particular to a preparation device and a preparation method of a modified material. Background Art
[0002] Modified materials are materials that have been specially treated to improve the performance of the original materials. By adding, removing or changing the composition of the material, new properties can be given to the material, such as improving strength, hardness, heat resistance, electrical conductivity, thermal conductivity, etc. Therefore, modified materials are widely used in the fields of automobiles, electronics, construction, and aerospace.
[0003] In the preparation process of some modified materials, a variety of preparation raw materials of the modified materials are often mixed with the help of a horizontal mixer, so that the various preparation raw materials can contact each other in all directions, thereby improving the performance of the modified materials themselves.

[0005] Referring to the above technical solution, when mixing granular raw materials and powdered raw materials, due to the difference in density between the two, as the stirring work continues, the powdered raw materials may sink and gather at the bottom of the inner cavity of the horizontal mixer. In this case, when the stirring and mixing work continues, the mixing uniformity of the granular raw materials and powdered raw materials is easily affected to a certain extent, thereby affecting the final quality and performance of the modified material. Summary of the invention

When the material box swings back and forth based on the frame, the push plate will move inside the circulating material chamber through the step-by-step driving of the differential gear and the large diameter gear ring, thereby pushing the granular raw materials and powdered raw materials entering the circulating material chamber out of the return port to complete the material circulation.
[0024] By adopting the above technical solution, the powdered raw materials originally gathered at the bottom of the inner cavity of the material holding box can be transferred to the upper part of the inner cavity of the material holding box, thereby realizing the circulation of the powdered raw materials and part of the granular raw materials.

[0026] By adopting the above technical solution, the raised powdered raw materials can be captured by negative pressure suction and made to participate in the mixing process again, so as to avoid changes in the proportion of raw materials required for preparing the modified material.

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 7 , the technical scheme of the embodiment of the present application is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present application, not all of the embodiments. Based on the described embodiment of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.
[0039] In a first aspect, the present application provides a device for preparing a modified material, which adopts the following technical solution:
[0040] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The present embodiment provides a modified material preparation device, including a frame 1, a material box 11 is rotatably connected to the frame 1, a stirring shaft 12 is rotatably connected to the middle of the material box 11, and a driving motor 13 for driving the stirring shaft 12 to rotate is arranged on the frame 1.
[0041] A circulation material chamber 2 is provided in the interlayer of the box wall of the material holding box 11, two return material ports 21 are provided in the middle of the inner wall of the material holding box 11, a drop material port 22 is provided at the bottom of the inner wall of the material holding box 11, and the two return material ports 21 and the drop material port 22 are both connected to the circulation material chamber 2, and two baffles 24 corresponding to the return material ports 21 one by one and capable of blocking the return material ports 21 are slidably connected to the inside of the circulation material chamber 2 through air supports 23.
[0042] A transmission member 3 is provided between the frame 1 , the material holding box 11 and the stirring shaft 12 , and is used to make the material holding box 11 reciprocate based on the frame 1 during the rotation of the stirring shaft 12 .
[0043] A large diameter gear ring 4 is rotatably connected to the material holding box 11, and a push plate 5 is provided at the edge of the large diameter gear ring 4, which penetrates the side wall of the material holding box 11 and extends to the inside of the circulating material chamber 2. A differential gear 6 meshing with the large diameter gear ring 4 is rotatably connected to the frame 1, and the differential gear 6 is connected to the material holding box 11 by belt drive.
[0044] When preparing the modified material, the operator first pours the granular raw material and the powdered raw material into the material container 11 together, and then drives the motor 13 to operate and drive the stirring shaft 12 to rotate, so that the granular raw material and the powdered raw material are mixed under the stirring action of the stirring shaft 12.
[0045] During the rotation of the stirring shaft 12, through the cooperation of the transmission part 3, the material box 11 can swing back and forth based on the frame 1, so that the powdered raw materials gathered at the bottom of the material box 11 are displaced, increasing the fluidity of the powdered raw materials and facilitating the uniform mixing of the granular raw materials and the powdered raw materials.
[0046] At the same time, due to the existence of the drop-out port 22, the powdered raw materials and part of the granular raw materials gathered at the bottom of the inner cavity of the material holding box 11 will enter the circulating material chamber 2 through the drop-out port 22, and the differential gear 6 will alternately rotate forward and reverse with the reciprocating swing of the material holding box 11 under the action of the belt drive. With the cooperation of the large-diameter gear ring 4, the push plate 5 can move inside the circulating material chamber 2 and push the granular raw materials and powdered raw materials inside the circulating material chamber 2 until the granular raw materials and powdered raw materials overcome the elastic supporting force of the gas support 23 to push open the baffle 24 and re-enter the inner cavity of the material holding box 11 through the return port 21, thereby transferring the powdered raw materials originally gathered at the bottom of the inner cavity of the material holding box 11 to the upper part of the inner cavity of the material holding box 11.
[0047] When the granular raw materials and the powdered raw materials are mixed, the operator can open the discharge hopper at the bottom of the material box 11, so that the final modified material passes through the drop port 22, the circulation material chamber 2 and the discharge hopper in sequence and is discharged from the material box 11.
[0048] Reference Figure 1 , Figure 4 and Figure 5 The transmission member 3 includes a driving gear 31, a driven gear 32, an eccentric protrusion 33 and a strip-shaped opening 34. The driving gear 31 is arranged on the stirring shaft 12, the driven gear 32 is rotatably connected to the frame 1 and can mesh with the driving gear 31, the eccentric protrusion 33 is arranged at the edge of the driven gear 32, and the material holding box 11 is provided with a strip-shaped opening 34 for the eccentric protrusion 33 to be inserted.
[0049] When the driving gear 31 rotates along with the stirring shaft 12 , the driven gear 32 meshing with the driving gear 31 rotates accordingly, thereby changing the relative position of the eccentric protrusion 33 in the strip opening 34 , so that the material container 11 swings back and forth under the positive and negative alternating push of the eccentric protrusion 33 .
[0050] Reference Figure 1 , Figure 2 and Figure 3 Two dust suction ports 7 connected to the circulating material chamber 2 are provided on the top of the inner wall of the material holding box 11, and two dust suction hoods 71 corresponding to the dust suction ports 7 one by one and capable of being connected to an external air pump are provided on the outer wall of the material holding box 11. A filter screen 72 for preventing powdered raw materials from passing through is provided inside the dust suction hood 71, and a plurality of reflux holes 73 for the powdered raw materials to pass through are provided on the baffle 24.
[0051] When the external air pump is running, the negative pressure it generates can suck the powdered raw materials raised during the stirring process into the top of the circulating material chamber 2 through the dust suction port 7, and then the powdered raw materials will enter the bottom of the circulating material chamber 2 through the reflux hole 73 to participate in the circulation, and the filter screen 72 can prevent the powdered raw materials from entering the dust suction hood 71 and being discharged.
[0052] Reference Figure 2 and Figure 3 The movable section of the gas support 23 is provided with a scraper 74 capable of abutting against the filter screen 72 .
[0053] During the extension and retraction process of the gas strut 23 , the scraper 74 located on the movable section of the gas strut 23 can scrape off the powdery raw materials attached to the filter screen 72 to prevent the powdery raw materials from clogging the filter screen 72 .
[0054] Reference Figure 1 and Figure 2 Two guide plates 8 corresponding to the dust suction ports 7 are arranged on the top of the inner wall of the material holding box 11, and the guide plates 8 are inclined from top to bottom toward the direction close to the stirring shaft 12.
[0055] When the granular raw materials and the powdered raw materials are poured into the material holding box 11, the guide plate 8 can prevent the granular raw materials and the powdered raw materials from directly entering the circulation chamber 2 and affecting the normal development of subsequent work.
[0056] The implementation principle of a preparation device for a modified material in the embodiment of the present application is as follows:
[0057] When preparing the modified material, the operator first pours the granular raw material and the powdered raw material into the material container 11 together, and then drives the motor 13 to operate and drive the stirring shaft 12 to rotate, so that the granular raw material and the powdered raw material are mixed under the stirring action of the stirring shaft 12.
[0058] During the rotation of the stirring shaft 12, the material box 11 can swing back and forth based on the frame 1 through the cooperation of the transmission member 3, so that the powdered raw materials gathered at the bottom of the material box 11 are displaced accordingly, which is beneficial to the uniform mixing of the granular raw materials and the powdered raw materials.
[0059] At the same time, due to the existence of the drop-out port 22, the powdered raw materials and part of the granular raw materials gathered at the bottom of the inner cavity of the material holding box 11 will enter the circulating material chamber 2 through the drop-out port 22, and the differential gear 6 will alternately rotate forward and reverse with the reciprocating swing of the material holding box 11 under the action of the belt drive. With the cooperation of the large-diameter gear ring 4, the push plate 5 can move inside the circulating material chamber 2 and push the granular raw materials and powdered raw materials inside the circulating material chamber 2 until the granular raw materials and powdered raw materials overcome the elastic supporting force of the gas support 23 to push open the baffle 24 and re-enter the inner cavity of the material holding box 11 through the return port 21, thereby transferring the powdered raw materials originally gathered at the bottom of the inner cavity of the material holding box 11 to the upper part of the inner cavity of the material holding box 11.
[0060] When the granular raw materials and the powdered raw materials are mixed, the operator can open the discharge hopper at the bottom of the material box 11, so that the final modified material passes through the drop port 22, the circulation material chamber 2 and the discharge hopper in sequence and is discharged from the material box 11.

[0064] S3, when the granular raw material and the powdery raw material are mixed, the discharge hopper at the bottom of the material holding box 11 is opened to discharge the final modified material out of the material holding box 11.
[0065] In S2, due to the existence of the drop port 22, the powdered raw materials and some granular raw materials gathered at the bottom of the inner cavity of the material box 11 will enter the circulating material chamber 2. When the material box 11 reciprocates based on the frame 1, the push plate 5 will move inside the circulating material chamber 2 through the step-by-step driving of the differential gear 6 and the large diameter gear ring 4, thereby pushing the granular raw materials and powdered raw materials entering the circulating material chamber 2 out from the return port 21 to complete the material circulation.
[0066] In S2, with the cooperation of the external air pump, the negative pressure generated by the dust suction port 7 can suck the powdered raw materials raised during the stirring process into the circulating material chamber 2, so that the raised powdered raw materials also participate in the material circulation process.
