Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 - 14 shown, an embodiment of the present invention provides a preparation device for producing bio-based synthetic leather, including a main housing 2, a support 1 fixedly connected to the main housing 2, an auxiliary housing 201 fixedly connected to the side of the main housing 2, a feed inlet provided at the upper part of the main housing 2, and further including: Referring to Figure 1 、 Figure 2, the main housing 2 is used to provide space and environment for the mixing of raw materials of bio-based synthetic leather, the bracket 1 is used to provide support for the whole device, the auxiliary housing 201 is used to provide protection for the transmission component, and the feed inlet is used for adding the raw materials of bio-based synthetic leather into the main housing 2.

[0021] The extrusion assembly 3, the extrusion assembly 3 is symmetrically arranged in the main housing 2. The extrusion assembly 3 includes a fixed plate 303 fixedly installed in the main housing 2. A plurality of sliding rods 305 are slidably connected to the fixed plate 303. The lower end of the sliding rod 305 is fixedly connected with an extrusion block 301, the upper end of the sliding rod 305 is fixedly connected with a top block 304, and extrusion springs 302 are symmetrically and fixedly connected between the extrusion block 301 and the fixed plate 303; Reference Figure 4 , Figure 5 , during the extrusion operation, since there are multiple extrusion blocks 301, each extrusion block 301 can move up and down independently. Due to the shape of the rotating part 6 in the shearing and mixing assembly 4, the raw materials will be driven upward by the rotating part 6. The extrusion block 301 will be pushed upward by the raw materials, and the extrusion spring 302 will be compressed by the extrusion block 301. The reaction force provided by the extrusion spring 302 can apply a downward pressure to the raw materials, so that the raw materials are fully extruded and dispersed. Moreover, the main extrusion blade 605 is arranged to gradually contract from the connecting cylinder 606 towards the rotating cylinder 601. Therefore, the extrusion force provided by the extrusion block 301 pushes the raw materials from the middle to both sides, making the raw materials flow. The sliding rod 305 is used to guide the movement of the extrusion block 301, and the top block 304 provides a limit for the movement of the extrusion block 301; it is suitable for mixing and processing even a large amount of raw materials, avoiding the adhesion of raw materials to the upper inner wall of the main housing 2, reducing the adhesion amount of raw materials, improving the utilization rate of raw materials, and reducing raw material loss.

[0022] The shearing and mixing assembly 4, the shearing and mixing assembly 4 is arranged below the extrusion assembly 3 and is axially symmetrically arranged. The shearing and mixing assembly 4 includes a rotating part 6 and a fixed part 7. The rotating part 6 rotates around the fixed part 7 to mix and shear the raw materials; Reference Figure 7 , Figure 8 , the rotating part 6 can rotate around the fixed part 7. The cooperation between the rotating part 6 and the fixed part 7 can realize the shearing and mixing operations of the raw materials. The rotating part 6 can provide mixing, extrusion and stretching operations for the raw materials, which is suitable for the preparation of bio-based synthetic leather.

[0023] The rotating member 6 includes two rotating cylinders 601 fixed together, two main extrusion blades 605, and a connecting cylinder 606. A secondary extrusion blade 603 is fixedly connected to the inner side of the main extrusion blade 605. A main shear blade group 602 is fixedly connected to the side of the main extrusion blade 605 facing the secondary extrusion blade 603. A secondary shear blade group 604 is fixedly connected to the side of the secondary extrusion blade 603 facing the main extrusion blade 605. The outer sides of the main extrusion blade 605 and the secondary extrusion blade 603 are gradually tapered from the connecting cylinder 606 towards the rotating cylinder 601, and the outer sides of the two main extrusion blades 605 face in opposite directions; Reference Figure 9 , when the two symmetric main extrusion blades 605 approach each other, the raw materials are pushed by the two symmetric main extrusion blades 605 to approach and squeeze each other, so that the raw materials are fully separated. When the two symmetric main extrusion blades 605 move away from each other, the raw materials are driven by the two symmetric main extrusion blades 605 to move away and stretch each other, so that the raw materials are fully stretched and damaged. The rotation of the secondary extrusion blade 603 can mix the raw materials and improve the mixing effect of the raw materials; both the main shear blade group 602 and the secondary shear blade group 604 are composed of multiple blades, which can cut the raw materials and improve the cutting effect of the raw materials.

[0024] The fixing member 7 includes a fixing rod 701, and a mating blade group 702 is symmetrically fixedly connected to the fixing rod 701. The mating blade group 702 is composed of multiple circular blades with gradually increasing radii, and a mating groove 703 is reserved between adjacent circular blades; Reference Figure 10 , Figure 11 , the mating blade group 702 is used to cooperate with the main shear blade group 602 and the secondary shear blade group 604 to restrict the movement of the raw materials and improve the efficiency of raw material cutting.

[0025] Both the main shear blade group 602 and the secondary shear blade group 604 are located in the mating groove 703. A shear cavity is reserved between the main shear blade group 602 and the secondary shear blade group 604 and the mating blade group 702. The fixing rod 701 is fixedly connected to the main housing 2, and the rotating cylinder 601 is rotatably connected to the fixing rod 701. The lower part of the main housing 2 is symmetrically provided with an arc surface 202 adapted to the main extrusion blade 605; Reference Figure 8 , the shear cavity is used to accommodate the sheared raw materials. The design of the arc surface 202 can enable the raw materials at the bottom to be fully driven by the rotating member 6, avoid the accumulation of raw materials at the bottom, and improve the mixing effect of the raw materials.

[0026] The circulation assembly 8 is arranged below the midpoint of the connection line of the two shear mixing assemblies 4. The circulation assembly 8 is used to gather the raw materials at both ends to the middle; The circulation assembly 8 includes a circulation rod 801 rotatably installed on the main housing 2. A forward spiral blade 803 and a reverse spiral blade 802 are fixedly connected to the circulation rod 801; ReferenceFigure 14 , Figure 5 , the movement trajectory of the circulation component 8 is tangent to the movement trajectory of the rotating component 6. When raw materials are filled in the main housing 2, the forward spiral blades 803 and the reverse spiral blades 802 will gather the raw materials at both ends to the middle. On the one hand, it makes the raw materials flow, increasing the shear and mixing of all raw materials. On the other hand, the mutual approach of the raw materials on both sides will also squeeze the raw materials, providing a supporting force for the extrusion, stretching and mixing operations of the rotating component 6.

[0027] Discharging component 5, the discharging component 5 is arranged directly below the circulation component 8 and is used to discharge the mixed raw materials; The discharging component 5 includes a discharging housing 501 fixedly installed at the bottom of the main housing 2. A discharging motor 504 is fixedly installed at the rear of the discharging housing 501. The output end of the discharging motor 504 is fixedly connected with an extrusion spiral blade 503. A discharging pipe 502 is fixedly connected to the front of the discharging housing 501. A closed channel 505 is arranged on one side wall of the discharging housing 501 close to the blocking component 9; Reference Figure 5 , Figure 6 , when the discharging motor 504 is powered on and operates, it drives the extrusion spiral blade 503 to rotate. Under the push of the extrusion spiral blade 503, the raw materials are discharged from the discharging pipe 502, facilitating the complete discharge of the mixed raw materials.

[0028] Blocking component 9, the blocking component 9 is arranged between the circulation component 8 and the discharging component 5 and is used to control the release of raw materials; The blocking component 9 includes a blocking housing 901. A blocking slide plate 904 is slidably connected in the blocking housing 901. An electromagnet 902 is fixedly installed outside the blocking housing 901. A magnetic part 9021 is arranged on the electromagnet 902. The magnetic part 9021 extends into the blocking housing 901. A permanent magnet 903 is fixedly connected to one side of the blocking slide plate 904 close to the magnetic part 9021. The magnetism of the permanent magnet 903 is opposite to the magnetism of the magnetic part 9021 after the electromagnet 902 is energized. A blocking spring 905 is fixedly connected between the blocking housing 901 and the blocking slide plate 904. The number of the blocking springs 905 is two and they are located outside the permanent magnet 903; Reference Figure 5 , Figure 13, in the blocking state, under the elastic force of the blocking spring 905, the blocking slide plate 904 passes through the closed channel 505 and inserts into the discharge housing 501, separating the discharge housing 501 from the main housing 2 to prevent the raw materials that have not been fully mixed and sheared from falling into the discharge housing 501; in the release state, the electromagnet 902 is energized to work, and the magnetic part 9021 generates a magnetic force. Since the magnetic part 9021 and the permanent magnet 903 have opposite magnetic polarities, the magnetic part 9021 will adsorb the permanent magnet 903, and the adsorption force is greater than the elastic force of the blocking spring 905. Therefore, the blocking slide plate 904 will slide into the interior of the blocking housing 901, and the discharge housing 501 and the main housing 2 are in communication with each other. Under the action of gravity, the raw materials can fall into the discharge housing 501.

[0029] A shearing motor 401 is installed on the auxiliary housing 201. The shearing motor 401 drives the shearing and mixing assembly 4 and the circulation assembly 8 to rotate through a transmission assembly. The rotation directions of the two shearing and mixing assemblies 4 are opposite. The transmission assembly includes two driving gears 402, a driven gear 403, and a follower gear 404. The two driving gears 402 are respectively meshed with the driven gear 403 and the follower gear 404. The two driving gears 402 are fixedly connected to the output end of the shearing motor 401. The driven gear 403 is fixedly connected to the circulation assembly 8. The driving gear 402 and the follower gear 404 are respectively symmetrically and fixedly connected to the two rotating members 6.

[0030] Reference Figure 3 , Figure 14 , when the shearing motor 401 is energized to work, it drives one side driving gear 402 to rotate, thereby driving the rotating member 6 on the same side to rotate. One side driving gear 402 drives the other side driving gear 402 to rotate in the opposite direction, thereby driving the rotating member 6 on the other side to rotate, making the rotation directions of the two rotating members 6 opposite. One side driving gear 402 also drives the driven gear 403 to rotate, thereby being able to drive the circulation assembly 8 to rotate, realizing that one power source drives multiple components and saving manufacturing costs.

[0031] Working principle: During use, the bio-based synthetic leather raw materials are added into the main housing 2 from the feed inlet; The shearing motor 401 is powered on to work, driving the driving gear 402 on one side to rotate, thereby driving the rotating member 6 on the same side to rotate. The driving gear 402 on one side drives the driving gear 402 on the other side to rotate in the opposite direction, thereby driving the rotating member 6 on the other side to rotate, making the rotation directions of the two rotating members 6 opposite. When the two main extrusion blades 605 that are symmetric to each other approach each other, the raw materials are pushed by the two main extrusion blades 605 that are symmetric to each other to approach and be extruded, so that the raw materials are fully separated. When the two main extrusion blades 605 that are symmetric to each other move away from each other, the raw materials are driven by the two main extrusion blades 605 that are symmetric to each other to move away and be stretched, so that the raw materials are fully stretched and damaged. The rotation of the auxiliary extrusion blade 603 can mix the raw materials and improve the mixing effect of the raw materials; the main shearing blade group 602 and the auxiliary shearing blade group 604 are both composed of multiple blades, which can cut the raw materials and improve the cutting effect of the raw materials. The cooperating blade group 702 is used to cooperate with the main shearing blade group 602 and the auxiliary shearing blade group 604 to limit the movement of the raw materials and improve the cutting efficiency of the raw materials. At the same time, since there are multiple extrusion blocks 301, each extrusion block 301 is independently movable up and down. Due to the shape of the rotating member 6 in the shearing and mixing assembly 4, the raw materials will be driven upward by the rotating member 6, and the extrusion block 301 will be pushed upward by the raw materials. The extrusion spring 302 is compressed by the extrusion block 301. The reaction force provided by the extrusion spring 302 can apply a downward pressure to the raw materials, so that the raw materials are fully extruded and dispersed. Moreover, the main extrusion blade 605 is arranged to gradually contract from the connecting cylinder 606 towards the rotating cylinder 601. Therefore, the extrusion force provided by the extrusion block 301 pushes the raw materials from the middle to both sides, making the raw materials flow. The slide rod 305 is used to guide the movement of the extrusion block 301, and the top block 304 provides a limit for the movement of the extrusion block 301; it is suitable for mixing and processing even a large amount of raw materials, avoiding the adhesion of the raw materials to the upper inner wall of the main housing 2, reducing the adhesion amount of the raw materials, improving the utilization rate of the raw materials, and reducing the raw material loss; The driving gear 402 on one side also drives the driven gear 403 to rotate, thereby being able to drive the circulating assembly 8 to rotate. When the raw materials are filled in the main housing 2, the forward spiral blade 803 and the reverse spiral blade 802 will gather the raw materials at both ends to the middle. On the one hand, it makes the raw materials flow, increasing the possibility that all the raw materials can be fully sheared and mixed. On the other hand, the mutual approach of the raw materials on both sides will also extrude the raw materials, providing a supporting force for the extrusion, stretching and mixing operations of the rotating member 6; The electromagnet 902 is powered on to work, and the magnetic part 9021 generates magnetic force. Since the magnetic part 9021 has the opposite magnetism to the permanent magnet 903, the magnetic part 9021 will adsorb the permanent magnet 903. The adsorption force is greater than the elastic force of the blocking spring 905. Therefore, the blocking slide plate 904 will slide into the interior of the blocking housing 901. The discharge housing 501 is communicated with the main housing 2. Under the action of gravity, the raw materials can fall into the discharge housing 501. The discharge motor 504 is powered on to work, driving the extrusion spiral blade 503 to rotate. Under the push of the extrusion spiral blade 503, the raw materials are discharged from the discharge pipe 502, which is convenient for discharging the mixed raw materials completely. Among them, an existing controller can be selected to control the actions of each component, and the power supply comes from the commercial power supply.
