Description

Technical Field

[0001] The invention belongs to the technical field of feed processing, in particular to a double-shaft mixer suitable for various materials. Background Art

[0002] In the process of animal husbandry, people often feed livestock and poultry to facilitate their growth. The feed production process needs to go through multiple processes, one of the most common is to mix a variety of raw materials together. In the process of feed mixing, a double-shaft mixer is often used.

[0003] A Chinese patent with the publication number CN101480586B discloses a double-shaft paddle mixer, which belongs to the field of feed processing technology in agricultural engineering, and is composed of a mixing chamber cavity 1, a rotating shaft, a strut and a paddle. There are two rotating shafts parallel to each other in the mixing chamber cavity, and 3 to 9 groups of struts perpendicular to the rotating shaft are fixedly connected to each rotating shaft in the axial direction. The two struts in each group are on the same straight line, and the struts of adjacent groups are staggered by 90°. The struts of each group on the two rotating shafts are staggered axially, and a paddle is installed at the other end of each strut. Each side of the paddle has 3 to 10 transparent blade grooves, and the angle between the paddle plane and the axis of the rotating shaft is 40° to 50°. When the double-shaft paddle mixer is working, the material in the mixing chamber cavity performs multiple compound movements under the action of the two oppositely rotating paddles, effectively destroying the formation of "fat globules" and improving the coefficient of variation of the mixing uniformity of the feed, improving the mixing uniformity of trace components in the formula feed, and effectively shortening the mixing time. The present invention is used for formula feed processing.

[0004] During the process of feed mixing, most of the feed gathers at the bottom of the equipment, and the existing mixing blades are mostly of the same shape, and it is impossible to make corresponding changes to the bottom where a large amount of feed is accumulated to improve the mixing effect; therefore, the present invention provides a double-shaft mixer that is suitable for a variety of materials. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a double-shaft mixer suitable for a variety of materials described in the present invention includes a pedestal, a mixing shell is installed above the pedestal, a pair of mixing shafts are rotatably connected inside the mixing shell, and multiple stirring frames are fixed outside the pair of mixing shafts, a limiting slide is fixed at one end of the stirring frame away from the mixing shaft, a mixing slider is slidably connected outside the limiting slide, four mixing rods are hinged between the mixing slider and the stirring frame, and the four mixing rods are hinged to each other in pairs, a follower magnet is fixed at one end of the mixing slider away from the stirring frame, and an induction magnet is fixed inside the pedestal; when working, the feed raw materials to be processed are put into the interior of the mixing shell, and then the drive component is started. The mixing shaft is driven to rotate, and the rotation of the mixing shaft drives the stirring frame to rotate. The rotation of the stirring frame drives the limit slide bar and the mixing slider to rotate, so that the feed is stirred and mixed during the rotation. In this process, the mixing slider will slide along the limit slide bar under the action of centrifugal force, thereby driving the mixing rod to move. When the mixing slider slides over the top of the induction magnet, under the action of the magnetic force, the mixing slider will slide toward the direction of the stirring frame, thereby driving the mixing rod to move and stretch the mixing rod, thereby expanding the contact area with the feed and improving the mixing effect of the feed. In this way, the shape of the mixing rod is changed during the mixing process, thereby expanding the contact area with the feed accumulated at the bottom and improving the mixing effect.

[0007] Preferably, the end of the mixing rod away from the stirring frame is rotatably connected to a push-pull block, and a crushing head is provided on the side of the push-pull block away from the mixing rod; when working, during the movement of the mixing rod, it will simultaneously push the push-pull block to move, and the movement of the push-pull block will drive the crushing head to move and impact the feed, and the impact can separate some clumped feed in the feed, thereby further improving the mixing effect of the feed.

[0008] Preferably, a mounting plate is fixed on one side of the crushing head close to the push-pull block, the mounting plate is slidably connected to the push-pull block, and a plurality of groups of limit springs are fixed between the mounting plate and the push-pull block; during operation, while the push-pull block drives the crushing head to move, the mounting plate inside the crushing head will drive the limit spring to bounce back and forth under the action of inertia force, thereby driving the crushing head to bounce, and after the crushing head bounces, it will reciprocate to crush the feed, thereby further improving the effect of removing clumped feed in the feed.

[0009] Preferably, a cleaning block is fixed to the end of the limiting slide bar away from the stirring frame, an expansion core is slidably connected inside the cleaning block, water permeable holes are opened inside the cleaning block and on both sides of the expansion core, a guide plate is fixed to the side of the expansion core away from the limiting slide bar, a plurality of groups of extension rods are fixed to the side of the guide plate away from the expansion core, and an elastic sheet is fixed to the side of the extension rod away from the guide plate; when working, during the movement of the limiting slide bar, it will simultaneously drive the cleaning block to move, and the movement of the cleaning block will thereby drive the movement of the elastic sheet, and the elastic sheet will scrape the inner wall of the mixing shell during the rotation to prevent the feed from accumulating in the dead corner and being unable to be effectively mixed. Once some solution needs to be added to the feed for mixing, during the rotation of the cleaning block, part of the solution will be injected into the expansion core through the water permeable hole, so that the expansion core will expand. After the expansion core expands, it will push the guide plate to move. The movement of the guide plate will drive the extension rod to move, and then push the elastic sheet to move and deform it. At the same time, the centrifugal force it receives increases. At this time, the elastic sheet will contact the inner wall of the mixing shell during the rotation, so as to scrape out the viscous feed attached to the inner wall of the mixing shell, prevent the feed from sticking to the inner wall of the mixing shell, improve the mixing effect, and also achieve the purpose of adapting to the mixing of various materials.

[0010] Preferably, the expansion core is slidably connected to a squeezing plate on a side away from the guide plate, and a pushing rod is fixed to the side of the squeezing plate away from the expansion core, and the pushing rod is through-connected with the cleaning block; during operation, during the rotation of the limit slide bar, the mixing slider outside it will contact the pushing rod under the action of centrifugal force and push the pushing rod to move, and the movement of the pushing rod will push the squeezing plate to move, and the movement of the squeezing plate will squeeze the expansion core, thereby squeezing out part of the solution in the expansion core, thereby effectively preventing the elastic sheet from contacting the inner wall of the mixing shell for a long time and causing significant wear, and extending the service life of the equipment, and when the mixing slider slides over the excitation magnet, the force acting on the pushing rod disappears at this time, so that the expansion core can absorb the solution normally to expand, and a plurality of excitation magnets can be arranged to be distributed at different positions, so that the inner wall of the mixing shell at different positions can be effectively cleaned as needed.

[0011] Preferably, a plurality of elastic rods are fixed to the outside of the extension rod, and a magnetic ball is fixed to one end of the elastic rod away from the extension rod; during operation, when the cleaning block rotates past the induction magnet, the magnetic ball will be simultaneously acted upon by the magnetic force, thereby pulling the elastic rod to deform it, and then the elastic rod will be reset during the process of driving the magnetic ball to swing back and forth, thereby causing the extension rod and the elastic sheet to collide and vibrate, and the vibration will cause part of the feed adhered to the elastic sheet to detach, thereby preventing a large amount of feed from adhering to the surface of the elastic sheet and preventing effective mixing.

[0012] Preferably, a buffer wheel is rotatably connected inside the mixing shell and located above the mixing shaft, and a ring made of flexible material is fixed to the outside of the buffer wheel; during operation, when the cleaning block drives the elastic sheet to slide over the buffer wheel, the buffer wheel will apply an extrusion force to the elastic sheet, thereby driving the elastic sheet to deform and then pushing the guide plate to squeeze the expansion core, further squeezing out the solution in the expansion core, preventing the elastic sheet from having long contact wear with the top of the inner wall of the mixing shell, thereby extending the service life of the equipment, and at the same time, the solution at the bottom of the mixing shell can be extracted to the top of the feed and then put into the mixing shell, thereby further accelerating the mixing effect between the feed and the solution.

[0013] Preferably, a friction ring is fixed to the outside of the limiting slide rod, a sliding ring is slidably connected to the outside of the friction ring, and the sliding ring is fixedly connected to the mixing slide rod; during operation, as the mixing slide rod slides along the limiting slide rod, the sliding ring and the friction ring inside the mixing slide rod will also contact and slide with each other, thereby generating heat through friction. This heat will increase the temperature of the limiting slide rod to a certain extent, thereby making it easier for the feed on the surface of the limiting slide rod to detach, thus avoiding a large amount of feed adhesion. At the same time, the increased temperature will also promote the mixing effect between the feeds to a certain extent.

[0014] Preferably, cleaning rings are fixed between both sides of the mixing slider and the limiting slide bar, and a fastening spring is fixed between the cleaning ring and the mixing slider; during operation, as the mixing slider slides, the cleaning ring will also slide at the same time, and during the sliding process of the cleaning ring, it will remove some difficult-to-clean feed attached to the surface of the limiting slide bar, thereby ensuring the friction effect between the friction ring and the sliding ring, and the fastening spring can keep the cleaning ring in a fit with the limiting slide bar.

[0015] Preferably, a plurality of sets of elastic connecting rods are fixed to one side of the mixing rod close to the limiting sliding rod, and a collision ball is fixed to the end of the elastic connecting rod away from the mixing rod; when working, during the movement of the mixing rod, it will simultaneously drive the movement of the elastic connecting rod, and the movement of the elastic connecting rod will in turn drive the movement of the collision ball, thereby further mixing the feed, and at the same time, under the action of inertial force, the collision ball will collide with the mixing rod, thereby shaking off the feed attached to the surface of the mixing rod, so that after the feed is emptied, the equipment can be idle for a period of time to effectively remove the feed attached to the surface of the equipment, which is convenient for subsequent cleaning by employees.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The double-shaft mixer adapted to a variety of materials described in the present invention is provided with a follower magnet and an inducing magnet. When the follower magnet rotates past the inducing magnet, the mixing slider will stretch the mixing rod under the action of the magnetic force, thereby expanding the contact area with the feed and improving the mixing effect of the feed. In this way, the shape of the mixing rod is changed during the mixing process, thereby expanding the contact area with the feed accumulated at the bottom and improving the mixing effect.

[0018] 2. The double-shaft mixer adapted to a variety of materials described in the present invention drives the collision ball to move through an elastic connecting rod to further mix the feed. At the same time, the collision ball collides with the mixing rod, thereby shaking off the feed attached to the surface of the mixing rod. In this way, after the feed is emptied, the equipment can be idle for a period of time to effectively remove the feed attached to the surface of the equipment, which is convenient for subsequent cleaning by employees.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] Embodiment 1

[0030] like Figures 1 to 3 As shown, a double-shaft mixer adapted to a variety of materials described in an embodiment of the present invention comprises a pedestal 1, a mixing shell 2 is installed above the pedestal 1, a pair of mixing shafts 3 are rotatably connected inside the mixing shell 2, a plurality of stirring frames 4 are fixed outside the pair of mixing shafts 3, a limiting slide bar 5 is fixed to one end of the stirring frame 4 away from the mixing shaft 3, a mixing slider 6 is slidably connected to the outside of the limiting slide bar 5, four mixing rods 7 are hinged between the mixing slider 6 and the stirring frame 4, and the four mixing rods 7 are hinged to each other in pairs, and a follower magnet 8 is fixed to one end of the mixing slider 6 away from the stirring frame 4, An induction magnet 9 is fixed inside the base 1; when in use, the feed raw materials to be processed are put into the mixing shell 2, and then the driving component is started to drive the mixing shaft 3 to rotate, and the mixing shaft 3 rotates to drive the stirring frame 4 to rotate, and the stirring frame 4 rotates to drive the limit slide bar 5 and the mixing slide block 6 to rotate, so that the feed is stirred and mixed during the rotation. In this process, the mixing slide block 6 slides along the limit slide bar 5 under the action of centrifugal force, thereby driving the mixing rod 7 to move. When the mixing slide block 6 slides over the top of the induction magnet 9, under the action of magnetic force, The mixing slider 6 will slide toward the stirring frame 4, thereby driving the mixing rod 7 to move so that the mixing rod 7 stretches out, thereby expanding the contact area with the feed and improving the mixing effect of the feed. It should be noted that the hinge of the mixing rod 7 should be closed to prevent the material from entering the hinge gap during the movement. At the same time, the feed particles to be processed are soft, and the particle diameter is much larger than the gap at the hinge, so as not to affect the rotation of the mixing rod 7. When processing feed that needs to add solvent, the sealing effect of the mixing rod 7 hinge should be ensured. At this time, when the solvent enters the hinge of the mixing rod 7, It will not affect the rotation of 7 when connected. It should be noted that the hinge of the mixing rod 7 should be cleaned in time after each processing is completed. It should be noted that when the mixing shell 2 is full of feed, the magnetic force applied by the driving magnet 9 to the follower magnet 8 should be able to push the mixing slider 6 to slide along the limiting slide bar 5, so that the shape of the mixing rod 7 is changed during the mixing process, thereby expanding the contact area with the feed accumulated at the bottom, thereby improving the mixing effect. It should be noted that the stirring frames 4 outside the two groups of mixing shafts 3 should be cross-distributed, so that there will be no impact when the two mixing shafts 3 rotate.

[0031] like Figure 3 As shown, the end of the mixing rod 7 away from the stirring frame 4 is rotatably connected to a push-pull block 10, and the side of the push-pull block 10 away from the mixing rod 7 is provided with a crushing head 11; when working, during the movement of the mixing rod 7, it will simultaneously push the push-pull block 10 to move, and the movement of the push-pull block 10 will drive the crushing head 11 to move and impact the feed, and the impact can separate some clumped feeds in the feed, thereby further improving the mixing effect of the feed.

[0032] like Figure 4 As shown, a mounting plate 12 is fixed to one side of the crushing head 11 close to the push-pull block 10, and the mounting plate 12 is slidably connected to the push-pull block 10, and a plurality of groups of limit springs 13 are fixed between the mounting plate 12 and the push-pull block 10; during operation, while the push-pull block 10 drives the crushing head 11 to move, the mounting plate 12 inside it will drive the limit spring 13 to bounce back and forth under the action of inertia force, thereby driving the crushing head 11 to bounce, and after the crushing head 11 bounces, it will reciprocate to crush the feed, thereby further improving the effect of removing agglomerated feed in the feed.

[0033] like Figure 3 and Figure 5As shown, a cleaning block 14 is fixed to one end of the limiting slide bar 5 away from the stirring frame 4, and an expansion core 15 is slidably connected inside the cleaning block 14. Water permeable holes 16 are provided inside the cleaning block 14 and on both sides of the expansion core 15. A guide plate 17 is fixed to the side of the expansion core 15 away from the limiting slide bar 5. A plurality of groups of extension rods 18 are fixed to the side of the guide plate 17 away from the expansion core 15. An elastic sheet 19 is fixed to the side of the extension rod 18 away from the guide plate 17. During operation, during the movement of the limiting slide bar 5, it will simultaneously drive the cleaning block 14 to move, and the movement of the cleaning block 14 will drive the movement of the elastic sheet 19. During the rotation, the elastic sheet 19 will scrape the inner wall of the mixing shell 2 to prevent the feed from accumulating in the dead corner and being unable to be effectively mixed. It should be noted that when the dry feed is centrifugally mixed, the elastic sheet 19 does not contact the inner wall of the mixing shell 2, and once a certain amount of feed needs to be added to the feed, the elastic sheet 19 will not contact the inner wall of the mixing shell 2. When some solutions are mixed, at this time, during the rotation of the cleaning block 14, part of the solution will be injected into the expansion core 15 through the water permeable hole 16, so that the expansion core 15 will expand. After the expansion core 15 expands, it will push the guide plate 17 to move. The movement of the guide plate 17 drives the extension rod 18 to move, and then pushes the elastic sheet 19 to move to deform it, and at the same time the centrifugal force it is subjected to increases. It should be noted that when the expansion core 15 is full of solution and expands, the sum of the movement distance of the guide plate 17 pushed by the expansion core 15 after expansion and the movement distance of the guide plate 17 pushed by the expansion core 15 after the centrifugal force increases is greater than the distance between the elastic sheet 19 and the inner wall of the mixing shell 2. At this time, the elastic sheet 19 will contact the inner wall of the mixing shell 2 during the rotation process, thereby scraping out the viscous feed attached to the inner wall of the mixing shell 2, preventing the feed from sticking to the inner wall of the mixing shell 2, improving the mixing effect, and also achieving the adaptability to the mixing of multiple materials.

[0034] like Figure 3As shown, the side of the expansion core 15 away from the guide plate 17 is slidably connected with an extrusion plate 20, and the side of the extrusion plate 20 away from the expansion core 15 is fixed with a push rod 21, and the push rod 21 is connected with the cleaning block 14; when working, during the rotation of the limit slide bar 5, the mixing slider 6 outside it will contact the push rod 21 under the action of centrifugal force and push the push rod 21 to move, and the movement of the push rod 21 will push the extrusion plate 20 to move, and the movement of the extrusion plate 20 will squeeze the expansion core 15, so as to squeeze out part of the solution in the expansion core 15, so that It effectively prevents the elastic sheet 19 from long-term contact with the inner wall of the mixing shell 2 to cause significant wear, thereby extending the service life of the equipment. When the mixing slider 6 slides over the actuating magnet 9, the force acting on the push rod 21 disappears, so that the expansion core 15 can absorb the solution normally and expand. By setting a plurality of actuating magnets 9 distributed at different positions, the inner wall of the mixing shell 2 at different positions can be effectively cleaned as needed. It should be noted that a spring is fixed between the extrusion plate 20 and the cleaning block 14 to facilitate the resetting of the extrusion plate 20, which is not directly drawn in this application.

[0035] like Figure 5 As shown, a plurality of elastic rods 22 are fixed to the outside of the extension rod 18, and a magnetic ball 23 is fixed to one end of the elastic rod 22 away from the extension rod 18; when working, when the cleaning block 14 rotates past the energizing magnet 9, the magnetic ball 23 at this time will be simultaneously acted upon by the magnetic force, thereby pulling the elastic rod 22 so that the long rod 18 collides with the elastic sheet 19 to generate vibration, and the vibration will cause part of the feed bonded to the elastic sheet 19 to detach, thereby preventing a large amount of feed from being bonded to the surface of the elastic sheet 19 and being unable to be effectively mixed.

[0036] like Figure 2 As shown, a buffer wheel 28 is rotatably connected inside the mixing shell 2 and located above the mixing shaft 3, and a ring made of flexible material is fixed to the outside of the buffer wheel 28; during operation, when the cleaning block 14 drives the elastic sheet 19 to slide over the buffer wheel 28, the buffer wheel 28 will apply an extrusion force to the elastic sheet 19, thereby driving the elastic sheet 19 to deform and then push the guide plate 17 to squeeze the expansion core 15, further squeezing out the solution in the expansion core 15, preventing the elastic sheet 19 from having a long contact wear with the top of the inner wall of the mixing shell 2, thereby extending the service life of the equipment, and at the same time, the solution at the bottom of the mixing shell 2 can be extracted to the top of the feed and then put into the mixing shell 2, thereby further accelerating the mixing effect between the feed and the solution.

[0037] like Figure 6As shown, a friction ring 24 is fixed to the outside of the limiting slide bar 5, and a sliding ring 25 is slidably connected to the outside of the friction ring 24, and the sliding ring 25 is fixedly connected to the mixing slide bar 6; when working, in the process of the mixing slide bar 6 sliding along the limiting slide bar 5, the sliding ring 25 and the friction ring 24 inside it will also contact and slide with each other, so that friction generates heat, and this heat will increase the temperature of the limiting slide bar 5 to a certain extent, so that the feed on the surface of the limiting slide bar 5 is easier to detach, avoiding a large amount of feed adhesion, and the increased temperature will also promote the mixing effect between the feeds to a certain extent.

[0038] like Figure 6 As shown, cleaning rings 26 are fixed between both sides of the mixing slider 6 and the limiting slide bar 5, and a fastening spring 27 is fixed between the cleaning ring 26 and the mixing slider 6; during operation, as the mixing slider 6 slides, the cleaning ring 26 will also slide at the same time, and as the cleaning ring 26 slides, it will remove some difficult-to-clean feed attached to the surface of the limiting slide bar 5, thereby ensuring the friction effect between the friction ring 24 and the sliding ring 25, and the fastening spring 27 can keep the cleaning ring 26 in a fit with the limiting slide bar 5.

[0039] Embodiment 2

[0040] like Figure 7 As shown, compared with Example 1, another implementation of the present invention is: a plurality of sets of elastic connecting rods 29 are fixed to one side of the mixing rod 7 close to the limiting slide rod 5, and a collision ball 30 is fixed to the end of the elastic connecting rod 29 away from the mixing rod 7; when working, during the movement of the mixing rod 7, it will simultaneously drive the elastic connecting rod 29 to move, and the movement of the elastic connecting rod 29 will in turn drive the collision ball 30 to move, thereby further mixing the feed, and at the same time, under the action of inertial force, the collision ball 30 will collide with the mixing rod 7, thereby shaking off the feed attached to the surface of the mixing rod 7, so that after the feed is emptied, the equipment can be idle for a period of time to effectively remove the feed attached to the surface of the equipment, which is convenient for subsequent cleaning by employees.

[0041] Working principle: It should be noted that a driving assembly is installed on the outside of the mixing shaft 3, and the driving assembly includes a belt, a roller, and a motor. The motor drives the belt to rotate, thereby driving the roller to rotate, and then driving the mixing shaft 3 to rotate. This technical solution is a prior art and will not be described in detail in this application. When in use, the feed raw materials to be processed are put into the interior of the mixing shell 2, and then the driving assembly is started to drive the mixing shaft 3 to rotate. The rotation of the mixing shaft 3 drives the stirring frame 4 to rotate. The rotation of the stirring frame 4 drives the limiting slide bar 5 and the mixing slide block 6 to rotate, so that the feed is stirred and mixed during the rotation. In this process, the mixing slide block 6 will slide along the limiting slide bar 5 under the action of centrifugal force, thereby driving the mixing rod 7 to move. When the mixing slide block 6 slides over the top of the induction magnet 9, under the action of the magnetic force, the mixing slide block 6 will slide in the direction of the stirring frame 4, thereby driving the mixing rod 7 to move so that the mixing rod 7 stretches, thereby expanding the contact area with the feed and improving the mixing effect of the feed. It should be noted that the hinge of the mixing rod 7 should be sealed to prevent the material from entering the hinge gap during movement. At the same time, the feed particles to be processed are soft, and their particle diameter is much larger than the gap at the hinge, so that the rotation of the mixing rod 7 will not be affected. When processing feed that requires the addition of solvent, the sealing effect of the hinge of the mixing rod 7 should be ensured, and at this time, the solvent will not affect the rotation of 7 when it enters the hinge of the mixing rod 7. It should be noted that the hinge of the mixing rod 7 should be cleaned in time after each processing. It should be noted that when the mixing shell 2 is full of feed, the magnetic force applied by the driving magnet 9 to the follower magnet 8 should be able to push the mixing slider 6 to slide along the limiting slider 5. In this way, the shape of the mixing rod 7 is changed during the mixing process, thereby expanding the contact area with the feed accumulated at the bottom, thereby improving the mixing effect. It should be noted that the stirring frames 4 outside the two groups of mixing shafts 3 should be cross-distributed, so that there will be no impact when the two mixing shafts 3 rotate;

[0042] During the movement of the mixing rod 7, it will simultaneously push the push-pull block 10 to move, and the movement of the push-pull block 10 will drive the crushing head 11 to move and impact the feed, and the impact can separate some feeds that are clumped together in the feed, further improving the mixing effect of the feed; and in the process of the push-pull block 10 driving the crushing head 11 to move, the internal mounting plate 12 will drive the limit spring 13 to bounce back and forth under the action of the inertia force, and then drive the crushing head 11 to bounce, and the crushing head 11 will reciprocate to crush the feed after bouncing, further improving the effect of removing the clumped feed in the feed;

[0043] During the movement of the limit slide bar 5, it will simultaneously drive the cleaning block 14 to move, and the movement of the cleaning block 14 will drive the elastic sheet 19 to move. During the rotation process, the elastic sheet 19 will scrape the inner wall of the mixing shell 2 to prevent the feed from accumulating in the dead corner and being unable to be effectively mixed. It should be noted that when the dry feed is centrifugally mixed, the elastic sheet 19 does not contact the inner wall of the mixing shell 2. Once some solution needs to be added to the feed for mixing, during the rotation of the cleaning block 14, part of the solution will be injected into the expansion core 15 through the water permeable hole 16, so that the expansion core 15 will expand, and the expansion core 15 will push the guide plate 17 to move. , the guide plate 17 moves, thereby driving the extension rod 18 to move, and then pushing the elastic sheet 19 to move and deform it, and at the same time the centrifugal force it receives increases. It should be noted that when the expansion core 15 is full of solution and expands, the sum of the movement distance of the guide plate 17 pushed by the expansion core 15 after expansion and the movement distance of the guide plate 17 pushed by the expansion core 15 after the centrifugal force increases is greater than the distance between the elastic sheet 19 and the inner wall of the mixing shell 2. At this time, the elastic sheet 19 will contact the inner wall of the mixing shell 2 during the rotation process, thereby scraping out the viscous feed attached to the inner wall of the mixing shell 2, preventing the feed from sticking to the inner wall of the mixing shell 2, improving the mixing effect, and also achieving the ability to adapt to the mixing of multiple materials;

[0044] During the rotation of the limit slide bar 5, the mixing slider 6 outside it will contact the push rod 21 under the action of centrifugal force and push the push rod 21 to move. The movement of the push rod 21 will push the extrusion plate 20 to move. The movement of the extrusion plate 20 will squeeze the expansion core 15, thereby squeezing out part of the solution in the expansion core 15. This can effectively prevent the elastic sheet 19 from contacting the inner wall of the mixing shell 2 for a long time and causing great wear, thereby extending the service life of the equipment. When the mixing slider 6 slides over the energizing magnet 9, the force acting on the push rod 21 disappears, so that the expansion core 15 can absorb the solution normally and expand. By setting a plurality of energizing magnets 9 distributed at different positions, the inner wall of the mixing shell 2 at different positions can be effectively cleaned as needed. It should be noted that a spring is fixed between the extrusion plate 20 and the cleaning block 14 to facilitate the resetting of the extrusion plate 20, which is not directly drawn in this application.

[0045] When the cleaning block 14 rotates past the energizing magnet 9, the magnetic ball 23 at this time will be simultaneously acted upon by the magnetic force, thereby pulling the elastic rod 22 to deform it, and then the resetting process of the elastic rod 22 will drive the magnetic ball 23 to shake back and forth, thereby causing the extension rod 18 and the elastic sheet 19 to collide and vibrate, and the vibration will cause part of the feed bonded to the elastic sheet 19 to separate, thereby preventing a large amount of feed from being bonded to the surface of the elastic sheet 19 and being unable to be effectively mixed; and when the cleaning block 14 drives the elastic sheet 19 to slide past the buffer wheel 28, the buffer wheel 28 will apply an extrusion force to the elastic sheet 19, thereby driving the elastic sheet 19 to deform and then pushing the guide plate 17 to squeeze the expansion core 15, further squeezing out the solution in the expansion core 15, preventing the elastic sheet 19 from having a long contact wear with the top of the inner wall of the mixing shell 2, thereby extending the service life of the equipment, and at the same time, the solution at the bottom of the mixing shell 2 can be extracted to the top of the feed and then put into the mixing shell 2, thereby further accelerating the mixing effect between the feed and the solution;

[0046] When the mixing slider 6 slides along the limit slider 5, the sliding ring 25 and the friction ring 24 inside it will also contact and slide with each other, so that friction generates heat. This heat will increase the temperature of the limit slider 5 to a certain extent, so that the feed on the surface of the limit slider 5 is easier to detach, avoiding a large amount of feed adhesion. At the same time, the increased temperature will also promote the mixing effect between the feeds to a certain extent. During the sliding process of the mixing slider 6, the cleaning ring 26 will also slide at the same time. During the sliding process of the cleaning ring 26, it will remove some difficult-to-clean feed attached to the surface of the limit slider 5, thereby ensuring the friction effect between the friction ring 24 and the sliding ring 25, and the fastening spring 27 can keep the cleaning ring 26 in a fitting state with the limit slider 5.

[0047] During the movement of the mixing rod 7, it will simultaneously drive the elastic connecting rod 29 to move, and the movement of the elastic connecting rod 29 will in turn drive the collision ball 30 to move, thereby further mixing the feed. At the same time, under the action of inertial force, the collision ball 30 will collide with the mixing rod 7, thereby shaking off the feed attached to the surface of the mixing rod 7. In this way, after the feed is emptied, the equipment can be idle for a period of time to effectively remove the feed attached to the surface of the equipment, which is convenient for subsequent cleaning by employees.
