Description

Technical Field

[0001] This utility model relates to the field of antioxidant preparation, and in particular to an antioxidant granulation device. Background Technology

[0002] Currently, most antioxidants on the market are prepared using screw extruders for granulation. The antioxidant raw materials are heated and melted, and then extruded into long strips through a screw rotating through a perforated plate. After cooling, they are granulated to obtain granular antioxidants. However, in our production process, we often need to prepare antioxidant particles with different particle diameters according to our needs. Each time we need to adjust the particle diameter, we need to change the discharge plate with a different orifice diameter, which is very troublesome.

[0003] Furthermore, a search revealed that the antioxidant granulation device disclosed in Chinese patent application number 202320787448.7 uses a replacement disc to switch the forming disc, thereby adjusting the discharge orifice diameter. Based on existing technology, it was found that during the process of rotating the replacement disc to switch the forming disc, in order to facilitate rotation, a certain gap will inevitably exist between the discharge outlet of the screw extruder and the forming disc. This results in poor connection between the discharge outlet and the forming disc, and during the extrusion process, the raw material will overflow from the gap to the outside of the disc, thus increasing the loss of raw material. Utility Model Content

[0004] The purpose of this invention is to provide an antioxidant granulation device to solve the problems mentioned in the background art.

[0005] The technical problem solved by this utility model is achieved through the following technical solution:

[0006] An antioxidant granulation device includes a base, a screw extruder, and a power source. The right end face of the screw extruder has an extrusion end. A partition plate is fixedly installed on the base. A conversion disc is rotatably connected to an extension on the upper surface of the partition plate. The conversion disc has several mounting cavities distributed on it, each cavity communicating with the extrusion end. A shaping tray is slidably installed in each cavity. Through holes corresponding to the discharge holes of the extrusion end are distributed in each shaping tray, and the diameters of the through holes in different shaping trays are different. Sliding cavity openings are equidistantly distributed in each cavity. An outer ring portion is provided on the outer surface of each shaping tray, and ear handle portions are equidistantly distributed on each outer ring portion. Each ear handle portion is slidably connected to a corresponding sliding cavity opening, and a return spring is connected between each ear handle portion and the bottom wall of the corresponding sliding cavity opening.

[0007] Preferably, an L-shaped plate is fixedly installed at the bottom of the outer ring portion, and a corrugated block is fixedly installed on the right end face of the screw extruder on the lower side of the extrusion end. The corrugated block has a concave arc portion in the middle, and the arc end of the L-shaped plate can slide against the surface of the corrugated block.

[0008] Preferably, a protrusion is provided at the edge of the outer ring of the extrusion end, and the protrusion can abut against the outer ring.

[0009] Preferably, the base is fixedly provided with a fixing part, the fixing part is fixedly mounted with a drive motor, the output end of the drive motor is fixedly connected to a rotating shaft, and a cutting tool is fixedly mounted on the rotating shaft.

[0010] Preferably, a collection chamber is detachably installed on the upper surface of the base.

[0011] Preferably, a feed funnel is fixedly installed on the partition, and the discharge port at the bottom of the feed funnel is connected to the screw extruder.

[0012] The advantages and positive effects of this utility model are:

[0013] This invention allows for the switching of the shaping disc by rotating a conversion disc. When the shaping disc is connected to the discharge hole of the extrusion end, the bottom end of the shaping disc is embedded in the inner cavity formed by the protrusion of the extrusion end. This ensures that the connecting surface of the bottom of the shaping disc is completely connected to the extrusion end, forming a tight connection with higher stability. The bottom of the outer ring abuts against the protrusion, and the surface of the shaping disc protrudes outward, which facilitates the cutting of the extruded raw material into particles. The raw material can fully pass through the through hole of the shaping disc during extrusion, effectively preventing the raw material from overflowing from the edges. Attached Figure Description

[0025] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0026] Please see Figure 1-5 This utility model provides an embodiment of an antioxidant granulation device, comprising a base 10, a screw extruder 14, and a power source 12. The output end of the power source 12 is fixedly connected to the screw in the screw extruder 14. An extrusion end 23 is provided on the right end face of the screw extruder 14, and the discharge port in the extrusion end 23 is interconnected with the extrusion chamber in the inner cavity of the screw extruder 14. A partition 11 is fixedly installed on the base 10, and a feed funnel 13 is fixedly installed on the upper end face of the partition 11. The discharge port at the bottom of the feed funnel 13 is interconnected with the feed bin in the screw extruder 14. A conversion disc 20 is rotatably connected to the extension of the upper end face of the partition 11. Eight mounting cavities 21 are distributed on the conversion disc 20, and each mounting cavity 21 can be interconnected with the extrusion end 23. A shaping tray 25 is slidably installed in each of the mounting cavities 21. Each shaping tray 25 has through holes corresponding to the discharge holes of the extrusion end 23. The through holes in the eight shaping trays 25 are set to eight different diameters. This allows for easy and efficient adjustment of the antioxidant particle diameter simply by rotating the conversion disc 20 to rotate the shaping tray 25 of the corresponding diameter to the position of the extrusion end 23. Each mounting cavity 21 has equidistantly distributed sliding cavity openings 22. Each shaping tray 25 has an outer ring portion 28 on its outer surface, and each outer ring portion 28 has equidistantly distributed ear handle portions 26. Each ear handle portion 26 is slidably connected to the corresponding sliding cavity opening 22, and a return spring is connected between each ear handle portion 26 and the bottom wall of the corresponding sliding cavity opening 22.

[0027] It is worth mentioning that, in this embodiment, an L-shaped plate 27 is fixedly installed at the bottom of the outer ring portion 28, and a corrugated block 24 is fixedly installed on the right end face of the screw extruder 14 on the lower side of the extrusion end 23. The corrugated block 24 has a concave arc portion in the middle, and the arc end of the L-shaped plate 27 can slide against the surface of the corrugated block 24. At the same time, a protrusion is provided at the outer edge of the extrusion end 23, and the protrusion can abut against the outer ring portion 28.

[0028] When it is necessary to adjust the particle diameter of the antioxidant particles, the conversion disc 20 is rotated to rotate the shaping disc 25 corresponding to the required diameter to the position corresponding to the extrusion end 23. As the conversion disc 20 rotates to move the shaping disc 25 to the position of the extrusion end 23, the L-shaped plate 27 extends and slides across the surface of the corrugated block 24. When the L-shaped plate 27 enters the concave arc portion in the middle of the corrugated block 24, the corrugated block 24 lifts the L-shaped plate 27, causing the entire shaping disc 25 to slide out partially, allowing the bottom of the shaping disc 25 to cross the protrusion of the extrusion end 23, thus allowing the... The bottom end of the shaping tray 25 is embedded in the inner cavity formed by the protrusion. When the L-shaped plate 27 slides to the concave arc portion in the middle of the corrugated block 24, the entire shaping tray 25 will return to its original position, allowing the bottom of the outer ring portion 28 to abut against the protrusion. At the same time, the surface of the shaping tray 25 will protrude outward, which facilitates the cutting of the extruded raw material into particles. It also allows the connecting surface at the bottom of the entire shaping tray 25 to be fully connected with the extrusion end 23, so that the raw material can fully pass through the through hole of the shaping tray 25 during extrusion, effectively preventing the raw material from overflowing from the edge and increasing the loss.

[0029] In another embodiment, a fixing part 16 is fixedly provided on the base 10, and a drive motor 17 is fixedly installed on the fixing part 16. The output end of the drive motor 17 is fixedly connected to a rotating shaft 18, and a cutting blade 19 is fixedly installed on the rotating shaft 18. When extruding raw materials, the drive motor 17 is started, so that the drive motor 17 drives the cutting blade 19 to granulate the extruded antioxidant raw materials.

[0030] In another embodiment, a collection chamber 15 is detachably installed on the upper surface of the base 10. The collection chamber 15 is located below the corrugated block 24, so that the cut particles can fall into the collection chamber 15 for collection.

[0031] In practice, workers first add the raw materials into the feed hopper 13, which then enters the feeding section of the screw extruder 14. Simultaneously, the power source 12 starts, driving the screw extruder 14. The screw in the extruder 14 carries the raw materials sequentially through the melting section and cooling section, finally extruding them from the extrusion end 23 through the extrusion channel. The extruded material then passes through the through-holes in the shaping disc 25 to form raw material strips of the required diameter. At this time, the drive motor 17 starts, driving the cutting blade 19 to rotate, continuously cutting the extruded raw material strips of the required diameter. The resulting particles fall into the collection chamber 15 for collection. When it is necessary to adjust the particle diameter of the antioxidant particles, the conversion disc 20 is rotated, moving the shaping disc 25 corresponding to the required diameter to the position corresponding to the extrusion end 23. When the conversion disc 20 moves the corresponding shaping disc 25 to the position of the extrusion end 23... The L-shaped plate 27 extends and slides across the surface of the corrugated block 24. When the L-shaped plate 27 enters the concave arc portion in the middle of the corrugated block 24, the corrugated block 24 lifts the L-shaped plate 27, causing the entire shaping tray 25 to slide out partially. This allows the bottom of the shaping tray 25 to cross the protrusion of the extrusion end 23, embedding the bottom of the shaping tray 25 into the inner cavity formed by the protrusion. When the L-shaped plate 27 slides to the concave arc portion in the middle of the corrugated block 24, the entire shaping tray 25 returns to its original position, allowing the bottom of the outer ring portion 28 to abut against the protrusion. At the same time, the surface of the shaping tray 25 protrudes outward, facilitating the cutting of the extruded material into particles. This also ensures that the connecting surface at the bottom of the shaping tray 25 is fully connected to the extrusion end 23, allowing the material to pass fully through the through holes of the shaping tray 25 during extrusion, effectively preventing material from overflowing from the edges and increasing losses.

[0032] It should be emphasized that the embodiments described in this utility model are illustrative and not limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
