Description

Technical Field

[0001] The invention belongs to the technical field of feed processing equipment, in particular to a feed production extruder. Background Art

[0002] A feed extruder is a piece of machinery specially used for feed processing and production. It mainly processes feed raw materials through mechanical extrusion to produce feed products that meet the needs of animal breeding. It integrates multiple functions. First, it can evenly mix a variety of feed raw materials such as grains, beans, protein powder, vitamins, minerals, etc. to ensure balanced feed nutrition. Secondly, it matures the materials during processing to improve the digestion and absorption rate of the feed. At the same time, high temperature has a sterilization and disinfection effect, extending the shelf life of the feed. Furthermore, the mixed and matured materials can be extruded into specific shapes and sizes such as granules, strips, and flakes to meet the feeding needs of different animals. The texture, taste and palatability of the feed can also be improved by adjusting process parameters and adding special additives.

[0003] When using a vertical ring die pelletizer to produce feed, three key processes are required: material filling, extrusion molding, and pellet cutting. When the existing device is in operation, multiple pressure rollers are usually installed inside the ring die. At this time, the ring die remains stationary, and the pressure rollers rotate. Then, the raw materials are squeezed through the close cooperation between the pressure rollers and the ring die. The extruded raw materials are squeezed out through the through holes opened on the surface of the ring die, and then cut by a cutter.

[0004] However, existing devices generally pour the raw materials directly into the interior of the ring die to contact the pressing roller. Since the ring die remains stationary, the raw materials are squeezed only by the movement of the pressing roller itself. Moreover, since there is an extrusion gap between the pressing roller and the ring die, a portion of the raw materials will always not be squeezed out after being squeezed, resulting in accumulation of raw materials in the gap, which affects the extrusion molding of the raw materials. Therefore, the present invention provides a feed production extruder. Summary of the Invention

[0009] Preferably, a partition is fixedly connected above the central wheel, a rotating rod is fixedly connected above the partition, six groups of cleaning plates are evenly arranged on the surface of the rotating rod, and a rubber pad is arranged between the partition and the ring.

[0010] Preferably, a cooperating component configured to cooperate with the extrusion component to intermittently discharge the feed when it is extruded is provided between the feeding bin and the discharging bin. The cooperating component includes an arc plate, a scraper and a driving gear.

[0011] Preferably, the arc plate is rotatably connected to the rotating rod, the end of the scraper close to the center of the arc plate is fixedly connected to the rotating rod, the lower end face of the arc plate is fixedly connected to a fixed plate, the outer surface of the fixed plate is fixedly connected to a fixed ring, and a sliding groove is provided inside the fixed ring, the outer side of the fixed ring is fixedly connected to a connecting plate, and the connecting plate is fixedly connected to the feeding bin.

[0012] Preferably, the interior of the fixing ring is rotatably connected to a driven rack, the outer side of the driven rack is meshedly connected to a driving gear, a second motor is provided below the driving gear, and the driving gear is fixedly connected to the rotating shaft of the second motor, a support plate is provided between the connecting plate and the second motor, and the connecting plate and the second motor are both fixedly connected to the support plate.

[0013] Preferably, a group of blanking plates are arranged between the two adjacent groups of connecting plates, and a spiral cylinder is fixedly connected to the side of the blanking plate close to the axis of the rotating rod. A spiral groove is provided on the inner surface of the spiral cylinder, and the spiral cylinder is slidably connected to several groups of matching rods through the internal spiral groove, and the lower end of the matching rod is fixedly connected to the driven rack.

[0014] Preferably, four groups of discharge ports are provided at four corners on the outside of the discharge bin, a receiving plate is provided directly below the discharge port, the receiving plate is detachably connected to the base, the first motor is slidably connected to the base, the angle between the pressure rollers is 120°, and multiple groups of cutters are provided on the outside of the ring die.

[0015] Preferably, the spiral drum is rotatably connected to the fixed plate, and the side of the blanking plate away from the axis of the rotating rod is in sliding contact with the feeding bin.

[0016] The beneficial effects of the present invention are as follows: 1. The feed production extruder described in the present invention drives the rotating drum to rotate through the spline in the middle position of the transmission shaft, and the rotation of the rotating drum drives the sleeve and the ring die above it to rotate. The rotation of the sleeve can also drive the ring gear to rotate. The meshing transmission of the ring gear drives the planetary gear to rotate. The planetary gear can drive the pressure roller to perform circular motion while rotating through the support rod. At the same time, since the circular motion directions of the ring die and the pressure roller are opposite, the raw materials inside the ring die can be fully extruded at this time, and insufficient extrusion will not occur, thereby preventing the raw materials from accumulating inside the ring die and affecting the quality of feed extrusion molding.

[0017] 2. The feed production extruder described in the present invention drives the driving gear to rotate through the rotation of the second motor, and the rotation of the driving gear engages the transmission to drive the driven rack to rotate inside the fixed ring. When the driven rack rotates, it drives the matching rod to pass through the inside of the spiral barrel. Since the inner surface of the spiral barrel is provided with a spiral groove, when the matching rod passes through the inside of the spiral barrel, the spiral barrel is forced to rotate, which can drive the blanking plate to swing downward at a certain angle, so that the blanking plate is opened for blanking work. At the same time, the rotation of the rotating rod can drive multiple groups of scrapers to move on the inner surface of the feeding bin, so that the raw materials poured into the feeding bin can be evenly dropped into the inside of the ring die through the blanking plate, which can effectively improve the extrusion quality of the raw materials by the pressure roller and have a good extrusion effect.

[0018] 3. The feed production extruder described in the present invention drives the cleaning plate to rotate by the rotation of the rotating rod. At this time, the rotation of the cleaning plate can contact the outer surface of the pressure roller, thereby cleaning the surface of the pressure roller. At the same time, since the pressure roller performs a circular motion while rotating, the position of the cleaning plate cleaning the surface of the pressure roller is constantly changing, which can effectively improve the quality of its surface cleaning. At the same time, the rotation of the rotating rod can also drive the rotation of multiple sets of scrapers. The rotation of the scrapers can clean the inner wall of the feeding bin, which can prevent mixing problems when other raw materials are subsequently poured into the feeding bin.

[0019] 4. The feed production extruder described in the present invention drives the first motor to move up and down through a hydraulic cylinder, so that the transmission shaft above the first motor moves, and the splines set at the top and middle position of the surface are adjusted by the movement of the transmission shaft, so as to realize the extrusion of raw materials and the discharge of raw materials. At the same time, it can also realize the cleaning of the raw materials remaining on the surface of the feeding bin and the connecting plate, so that they are completely extruded and formed, which can effectively prevent the raw materials from adhering to the surface of the pressure roller and the inner wall of the feeding bin, realize the self-cleaning function of the device, and improve the efficiency and quality of subsequent raw material extrusion molding.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figures 1 to 3 As shown, a feed production extruder includes a feeding bin 1 and a discharging bin 2, wherein an extrusion assembly 100 configured to extrude feed is provided inside the discharging bin 2; The extrusion assembly 100 includes a planetary gear 104 and a pressure roller 105. The planetary gear 104 is meshedly connected to the ring gear 107. The planetary gear 104 is also meshedly connected to the center wheel 109. A rotating cylinder 103 is provided below the center wheel 109. The surface of the ring gear 107 is fixedly connected to the ring 9, and the ring die 108 is fixedly connected to the top of the ring 9.

[0024] During operation, as the rotating cylinder 103 rotates, the sleeve ring 9 is driven to rotate, and the sleeve ring 9 drives the ring gear 107 to rotate, the ring gear 107 meshes with the transmission to drive the planetary gear 104 to rotate, and the planetary gear 104 meshes with the transmission to drive the center gear 109 to rotate. It should be noted that at this time, since the ring gear 107 and the planetary gear 104 are meshed and connected, when the ring gear 107 rotates following the sleeve ring 9, the planetary gear 104 will perform a circular motion while rotating, and the circular motion of the planetary gear 104 is opposite to the rotation direction of the ring gear 107, and the ring die 108 is fixedly connected to the top of the sleeve ring 9. At this time, the rotation of the ring die 108 The direction will be opposite to the circumferential rotation direction of the planetary gear 104, that is, the rotation direction of the pressure roller 105 is opposite to that of the ring die 108. At this time, the pressure roller 105 performs circular motion while rotating, and can cooperate with the ring die 108. At this time, the raw materials inside the ring die 108 can be fully squeezed, which can effectively improve the efficiency of raw material extrusion. It should be noted again that since there will always be an extrusion gap between the ring die 108 and the pressure roller 105, the movement of the ring die 108 can actively drive the raw materials and the pressure roller 105 to cooperate with each other for extrusion, which can effectively reduce the raw materials in the extrusion gap and avoid the accumulation of a large amount of raw materials.

[0025] like Figures 1 to 3 As shown, the extrusion assembly 100 also includes a first motor 101 and a transmission shaft 102. The surface of the transmission shaft 102 is segmented and provided with two sets of splines, and the two sets of splines are respectively arranged at the top and the middle position of the transmission shaft 102. The bottom of the discharge bin 2 is fixedly connected to the base 5 through a fixed rod. A hydraulic cylinder is provided inside the base 5, and the hydraulic cylinder can drive the first motor 101 to move up and down. Spline grooves are provided inside the rotating cylinder 103 and the center wheel 109. The spline grooves of the rotating cylinder 103 cooperate with the splines in the middle position of the transmission shaft 102, and the spline grooves of the center wheel 109 cooperate with the splines at the top of the transmission shaft 102. The bottom of the pressure roller 105 is fixedly connected to the planetary gear 104, and the transmission shaft 102 is fixedly connected to the output end of the first motor 101.

[0026] During operation, the hydraulic cylinder is first started to drive the first motor 101 to move downward. The downward movement of the first motor 101 can drive the transmission shaft 102 to move. Before the raw material is extruded, the spline in the middle position of the transmission shaft 102 is matched with the rotating cylinder 103. It should be noted that the rotation of the transmission shaft 102 can drive the sleeve 9 above the rotating cylinder 103 to rotate, and the rotation of the sleeve 9 can drive the ring die 108 to rotate. Because the sleeve 9 and the ring gear 107 are fixedly connected, the ring gear 107 will mesh with the transmission to drive the planetary gear 104 to rotate. The rotation of the planetary gear 104 will drive the pressure roller 105 to rotate while rotating. Since the rotation direction of the ring die 108 is opposite to the circumferential rotation direction of the planetary gear 104, the rotation of the ring die 108 can fully cooperate with the pressure roller 105 to fully extrude the raw material. When the hydraulic cylinder is started to drive the first motor 101 to move upward, after the raw material is extruded, the spline in the middle position of the transmission shaft 102 cooperates with the center wheel 109. At this time, the center wheel 109 rotates, and the rotating cylinder 103 and the ring 9 above it no longer rotate. The rotation of the center wheel 109 will continue to engage the transmission to drive the planetary gear 104 and the pressure roller 105 above it to rotate, so that the remaining small amount of raw material can be extruded and formed without causing waste of raw materials.

[0027] like Figures 1 to 4 As shown, a support rod 110 is fixedly connected to the bottom of the planetary gear 104, and the upper end of the support rod 110 is slidably connected to the center wheel 109, the discharge bin 2 is rotatably connected to the sleeve ring 9, the interior of the ring die 108 is tightly matched with the pressure roller 105, and the upper end of the pressure roller 105 is fixedly connected to a semicircular plate 106, and the upper surface of the semicircular plate 106 is convex, the support rod 110 is movably connected to the limit bin 8, and the bottom surface of the limit bin 8 is provided with a slide groove, and the upper end of the limit bin 8 is fixedly connected to the lower end of the sleeve ring 9.

[0028] During operation, when the pressure roller 105 rotates while rotating, the rotation of the pressure roller 105 can drive the semicircular plate 106 to rotate. When part of the raw material falls on the top of the pressure roller 105, it will directly contact the semicircular plate 106 and fall from its surface to both sides of the pressure roller 105, which can prevent the raw material from falling on the top of the pressure roller 105 and preventing the pressure roller 105 from squeezing it. It should be noted that since the interior of the ring die 108 is tightly matched with the pressure roller 105, when the raw material appears on the side of the pressure roller 105, the pressure roller 105 will directly squeeze the raw material into the through holes on the surface of the ring die 108, which can effectively prevent the raw material from continuing to move with the pressure roller 105 after falling around the pressure roller 105, and can prevent the pressure roller 105 from incomplete squeezing.

[0029] like Figures 1 to 5 and Figure 8 As shown, a partition 111 is fixedly connected above the center wheel 109, a rotating rod 112 is fixedly connected above the partition 111, six groups of cleaning plates 113 are evenly arranged on the surface of the rotating rod 112, and a rubber pad 6 is arranged between the partition 111 and the ring 9.

[0030] During operation, the rotation of the center wheel 109 drives the partition 111 to rotate, and the rotation of the partition 111 drives the rotating rod 112 and the cleaning plate 113 to rotate. It should be noted that since the rotating rod 112 and the cleaning plate 113 are arranged at the center position of the three sets of pressing rollers 105, even if the raw materials are brought to the center position by the pressing rollers 105, the rotation of the cleaning plate 113 can still push the raw materials out, thereby preventing the raw materials from accumulating at the center position of the pressing rollers 105. It should also be noted that the support rod 110 is not fixed. When the planetary gear 104 and the pressure roller 105 rotate, the support rod 110 will also be driven to rotate while rotating. At this time, there will be a gap between the partition 111 and the ring 9. When the raw material falls into the interior of the ring die 108, even if the support rod 110 rotates while rotating, since the rubber pad 6 is made of elastic rubber, when the support rod 110 runs to a certain position, deformation will occur at a certain position. At this time, the raw material will be isolated by the rubber pad 6, which can prevent the raw material from falling through the gap between the partition 111 and the ring 9 to the position of multiple sets of planetary gears 104, thereby avoiding damage to the planetary gear 104.

[0031] like Figures 1 to 5 As shown, a mating component 200 is provided between the feeding bin 1 and the discharging bin 2 and is configured to cooperate with the extrusion component 100 to intermittently discharge the feed when extruding the feed. The mating component 200 includes an arc plate 201 and a scraper 202. The arc plate 201 is in sliding contact with the scraper 202. The side of the scraper 202 is in sliding contact with the feeding bin 1, and the scraper 202 is L-shaped. The end of the scraper 202 close to the center of the arc plate 201 is fixedly connected to the rotating rod 112; the arc plate 201 is rotatably connected to the rotating rod 112, and the lower end face of the arc plate 201 is fixedly connected to the fixing plate 203, and the outer surface of the fixing plate 203 is fixedly connected to the fixing ring 205, and the interior of the fixing ring 205 is provided with a slide groove, and the outer side of the fixing ring 205 is fixedly connected to the connecting plate 204, and the connecting plate 204 is fixedly connected to the feeding bin 1.

[0032] During operation, when the spline on the top of the transmission shaft 102 cooperates with the center wheel 109, the center wheel 109 will serve as the main force to drive the partition 111 and the rotating rod 112 above it to rotate. The rotation of the rotating rod 112 can drive multiple groups of scrapers 202 to move on the inner wall of the feeding bin 1 and the surface of the arc plate 201. It should be noted that at this time, the rotation of the scraper 202 can scrape and clean the inner wall of the feeding bin 1 to prevent the raw materials from adhering to its surface and clean it. At the same time, the rotation of the center wheel 109 can also drive the pressure roller 105 to rotate while rotating, which can effectively assist the pressure roller 105 to squeeze the remaining raw materials. There will be no phenomenon that a small amount of raw materials will not be squeezed, which can improve the utilization rate of the raw materials and will not cause waste of raw materials.

[0033] like Figures 4 to 10As shown, the internal rotation of the fixed ring 205 is connected to the driven rack 206, and the outer side of the driven rack 206 is meshed with the driving gear 211. A second motor 210 is provided below the driving gear 211, and the driving gear 211 is fixedly connected to the rotating shaft of the second motor 210. A support plate is provided between the connecting plate 204 and the second motor 210, and the connecting plate 204 and the second motor 210 are fixedly connected to the support plate; a group of blanking plates 209 are provided between the two groups of connecting plates 204, and the side of the blanking plate 209 close to the axis of the rotating rod 112 is fixedly connected to a spiral cylinder 208, and a spiral groove is provided on the inner surface of the spiral cylinder 208. The spiral cylinder 208 is slidably connected to several groups of matching rods 207 through the internal spiral groove, and the lower end of the matching rod 207 is fixedly connected to the driven rack 206.

[0034] During operation, the second motor 210 is started to rotate and drive the driving gear 211 to rotate. The driving gear 211 will mesh with the transmission to drive the driven rack 206 to rotate inside the fixed ring 205. The driven rack 206 drives the multiple groups of matching rods 207 above to rotate. When the matching rods 207 move to the inside of the spiral cylinder 208, the matching rods 207 will contact the spiral grooves opened inside the spiral cylinder 208, so that the spiral cylinder 208 is forced to rotate downward at a certain angle. It should be noted that because the lower end of the matching rod 207 is fixedly connected to the driven rack 206, the rotation angle of the spiral cylinder 208 can be controlled by the rotation angle of the driven rack 206 driven by the driving gear 211. In addition, since there is only one set of blanking plates 209 between the two sets of connecting plates 204, when the angle between the two sets of pressure rollers 105 is about to move to the bottom of the blanking plate 209, the second motor 210 will be started to move the blanking plate 209 to flip it, which can control the position of the raw material passing through the blanking plate 209 to accurately fall to the angle between the two sets of pressure rollers 105. It should also be noted that the width of the spiral groove on the inner surface of the spiral cylinder 208 is the same as the diameter of the matching rod 207, which can avoid the matching rod 207 from getting stuck after being inserted into the interior of the spiral cylinder 208.

[0035] like Figure 1 、 Figure 8 and Figure 9 As shown, four groups of discharge ports 3 are distributed at the four corners on the outside of the discharge bin 2, and a receiving plate 4 is provided directly below the discharge port 3. The receiving plate 4 and the base 5 are detachably connected, the first motor 101 and the base 5 are slidably connected, the angle between the pressure rollers 105 is 120°, and multiple groups of cutters 7 are provided on the outside of the ring die 108.

[0036] During operation, the circular motion of the ring die 108 cooperates with the cutter 7 to quickly and effectively cut the extruded feed into equal lengths. The cut feed will be transported to the position of the receiving plate 4 through the discharge port 3 for collection, which can make it more convenient for the staff to observe the cut feed to ensure the quality of the feed extrusion. It should be noted that when the length of the cut feed needs to be adjusted, the distance between the cutter 7 and the ring die 108 needs to be adjusted to ensure that there is no large error in the length of the cut feed.

[0037] like Figures 2 to 5 As shown, the spiral drum 208 is rotationally connected to the fixed plate 203, and the side of the blanking plate 209 away from the axis of the rotating rod 112 is in sliding contact with the feeding bin 1.

[0038] During operation, when the spiral drum 208 is forced to rotate at a certain angle, since the spiral drum 208 is rotatably connected to the fixed plate 203, one end of the discharge plate 209 driven by the rotation of the spiral drum 208 will contact the side of the feeding bin 1 and flip downward or upward. When the discharge plate 209 is not opened, the feed will not fall into the inside of the ring die 108, which can improve the accuracy of the discharge of the discharge plate 209 and facilitate the extrusion of the pressure roller 105.

[0039] Working principle: After the present invention is installed, first put an appropriate amount of raw materials into the feeding bin 1, and then control the hydraulic cylinder to drive the first motor 101 to move downward. The downward movement of the first motor 101 can drive the spline in the middle position of the surface of the transmission shaft 102 to connect with the spline groove provided inside the rotating cylinder 103. At this time, the hydraulic cylinder stops moving, and at the same time, the first motor 101 is started to rotate to drive the rotating cylinder 103 to rotate. The rotation of the rotating cylinder 103 can drive the sleeve 9 and the ring die 108 above it to rotate inside the discharge bin 2, and the rotation of the sleeve 9 can drive the ring gear 107 to rotate. The ring gear 107 will engage the transmission to drive multiple sets of planetary gears 104 to rotate. At this time, since the spline on the top of the transmission shaft 102 is not connected to the spline groove inside the center wheel 109, the center wheel 109 is in a stationary state. Since the meshing transmission of the ring gear 107 drives the planetary gear 104 to rotate, the rotation of the planetary gear 104 can drive the pressure roller 105 to rotate through the support rod 110, and since the pressure roller 105 is meshed with the center gear 109 and the ring gear 107 at the same time, the pressure roller 105 can also perform circular motion while rotating, and the ring die 108 is fixedly connected to the sleeve ring 9, and the sleeve ring 9 is fixedly connected to the ring gear 107, so the direction of the circular motion of the pressure roller 105 is opposite to the direction of rotation of the ring die 108, and the rotation of the ring die 108 can also drive the raw material to move by friction, and the rotation and revolution of the pressure roller 105 can also drive the raw material to move, so that the raw material falling into the ring die 108 can be better extruded, and the phenomenon of incomplete extrusion of the raw material inside the ring die 108 after the raw material falls can be avoided, which can effectively improve the extrusion efficiency; In order to avoid the phenomenon of insufficient subsequent extrusion caused by the raw materials being directly put into the ring die 108 for extrusion during the blanking process, when the multiple sets of pressure rollers 105 are extruded inside the ring die 108, since the multiple sets of pressure rollers 105 are set at an angle of 120 degrees, an angle will be generated between the two sets of pressure rollers 105. At this time, the second motor 210 is started to rotate and drive the driving gear 211 to rotate forward. The driving gear 211 engages with the transmission to drive the driven rack 206 to rotate inside the fixed ring 205. The rotation of the driven rack 206 can drive the matching rod 207 to move. When the matching rod 207 When moving to the inside of the spiral drum 208, the matching rod 207 will cooperate with the spiral groove provided on the inner surface of the spiral drum 208, thereby driving the spiral drum 208 to rotate. The rotation of the spiral drum 208 can drive the blanking plate 209 to rotate downward by a certain angle. At this time, the raw materials inside the feeding bin 1 can fall into the gap between the two sets of pressure rollers 105 inside the ring die 108 in advance through the blanking plate 209, which can prevent the raw materials from falling above the pressure rollers 105 and causing insufficient extrusion of the raw materials, facilitate the extrusion molding work of multiple sets of pressure rollers 105, and avoid the accumulation of raw materials. When the gap position between the two sets of pressure rollers 105 changes, the second motor 210 is started to drive the driving gear 211 to reverse, so that the blanking plate 209 is flipped upward and flush with the connecting plate 204 again and no longer blanking is performed. When the gap position between the two sets of pressure rollers 105 is about to change to below the blanking plate 209, the second motor 210 is started in advance to perform the blanking work, which can cooperate with the work of the pressure rollers 105 during extrusion, so that the raw material can accurately fall into the gap between the two sets of pressure rollers 105, so that the raw material can fully contact the outer surface of the pressure rollers 105 and the inner surface of the ring die 108, which can effectively improve the quality of the raw material extrusion molding; Even if part of the raw material falls onto the top of the pressing roller 105, since the semicircular plate 106 is fixedly connected to the top of the pressing roller 105 and the pressing roller 105 can also rotate on its own when rotating in a circular motion, the rotation of the pressing roller 105 can drive the semicircular plate 106 to rotate rapidly. At this time, the raw material falling onto the top of the pressing roller 105 will be dispersed around the pressing roller 105 due to the semicircular plate 106. Moreover, since a cleaning plate 113 is provided at the center position of the three groups of pressing rollers 105, when the rotating rod 112 drives the cleaning plate 113 to rotate, the cleaning plate 113 can push the raw material located at the center position of the three groups of pressing rollers 105 outward, thereby preventing the raw material from being squeezed at the center position of the three groups of pressing rollers 105. When the extruded raw material is discharged through the through-holes on the surface of the ring die 108, the cutter 7 located on the outside thereof can cut the raw material. By adjusting the distance between the cutter 7 and the surface of the ring die 108, the length of the cut raw material can be controlled. Since the rotation of the ring die 108 can drive the cut feed, when the feed moves to the multiple discharge ports 3 provided on the outside of the discharge bin 2, the feed will fall through the discharge ports 3 to the inside of the receiving plate 4 for collection. After the raw material is extruded and molded, the first motor 101 and the second motor 210 are first turned off to rotate, and the hydraulic cylinder is started to drive the first motor 101 to move upward until the spline on the top of the transmission shaft 102 is inserted into the inside of the center wheel 109. At this time, the spline located in the middle position of the transmission shaft 102 is no longer in contact with the spline groove provided in the rotating cylinder 103. When the first motor 101 is started again to rotate, it will drive the center wheel 109 to rotate, and the center wheel 109 drives the rotating rod 112 and the cleaning plate 113 to rotate through the partition 111. The rotation of the rotating rod 112 can drive multiple sets of scrapers 202 to rotate on the inner wall of the feeding bin 1, which can scrape off the raw material adhered to the inner surface of the feeding bin 1 and make it fall to the position of the connecting plate 204. At the same time, the second motor 210 is also started to move and drive the blanking plate 209 to rotate forward and reverse again, so that the raw material adhered to the inner wall of the feeding bin 1 falls into the inside of the ring die 108, which is convenient for extruding the remaining raw material; Since the spline at the middle position of the transmission shaft 102 is no longer in contact with the spline groove provided in the rotating cylinder 103, the rotating cylinder 103 will no longer drive the ring die 108 above the sleeve 9 to rotate, and the rotating center wheel 109 can still drive the pressure roller 105 to rotate while performing a circular motion, so as to extrude the remaining raw materials, and the rotation of the scraper 202 can not only scrape the inner wall of the feeding bin 1, but also push the surface of the arc plate 201 and the raw materials remaining on the surface of the connecting plate 204 below. Since the surface of the arc plate 201 is arranged in an arc shape, the raw materials will move toward the position of the connecting plate 204 and the blanking plate 209 when being pushed, so that the blanking plate 209 can be opened and the remaining raw materials will be pushed into the interior of the ring die 108, which is convenient for extrusion and will not affect the subsequent raw materials being put into the feeding bin 1 and mixed with the original raw materials. At the same time, the rotation of the rotating rod 112 drives the cleaning plate 113 to rotate, and the cleaning plate 113 rotates and contacts the outer surface of the pressure roller 105. At this time, the cleaning plate 113 can wipe the surface of the pressure roller 105 and complete the function of cleaning its surface. At the same time, since the pressure roller 105 can perform a circular motion when rotating, the contact position between the surface of the pressure roller 105 and the cleaning plate 113 is constantly changing. Therefore, the cleaning plate 113 will not wipe only a certain part of the surface of the pressure roller 105, which can improve the quality of cleaning the surface of the pressure roller 105. Even when the spline on the top of the transmission shaft 102 does not contact the spline groove formed on the center wheel 109, at this time, since the upper end surface of the transmission shaft 102 is still in contact with the center wheel 109, when the rotating cylinder 103 rotates, the center wheel 109 will still be driven to move through the ring gear 107 and the planetary gear 104. At this time, the center wheel 109 will rotate passively, and the rotation of the center wheel 109 can also drive the scraper 202 above the rotating rod 112 to rotate slowly on the inner wall of the feeding bin 1, which can prevent the raw materials from accumulating on the connecting plate 204 and the arc plate 201 inside the feeding bin 1, thereby affecting the unloading of the blanking plate 209; Since the positions of the multiple sets of blanking plates 209 are fixed, but the gap between the two sets of pressing rollers 105 is movable, when the gap between the two sets of pressing rollers 105 is about to move to the blanking position of the blanking plate 209, the second motor 210 will drive the driving gear 211 to move in advance until the gap between the two sets of pressing rollers 105 moves to below the blanking plate 209. Only then can the raw material be accurately dropped into the gap, which facilitates the pressing rollers 105 to extrude and shape it. And since there are multiple groups of second motors 210 below the connecting plate 204, when the second motors 210 move, multiple groups move simultaneously, so as to ensure that after the blanking plate 209 completes the forward rotation and unloading, the multiple groups of driving gears 211 can quickly drive the driven rack 206 to reverse, which can effectively prevent the blanking plate 209 from rotating forward and unloading for too long, resulting in the accumulation of raw materials or a large amount of raw materials falling onto the top of the pressure roller 105.
