Description

Technical Field

[0001] This utility model relates to the field of pellet making machine technology, and in particular to a pellet making machine. Background Technology

[0002] A pellet-making machine is a mechanical production equipment that processes materials into pellet-shaped finished products. It is widely used in many fields such as food processing and pharmaceutical production. Pellet-making machines have many advantages, such as high degree of automation, convenient operation, and fast pellet-making speed.

[0003] During the pelleting process, the pelleting machine generates a lot of heat inside. The heat accumulates inside the device, affecting its normal operation and shortening its service life. Existing pelleting machines generally only have heat dissipation holes, which are not very effective and the heat dissipation process is slow. Existing heat dissipation mechanisms are generally located inside the pelleting machine, which is time-consuming, laborious, and inconvenient to clean.

[0004] Because the materials have a certain viscosity, after the pellet rolling roller forms pellets, they will still stick to the grooves on the surface of the roller. Therefore, a brush is needed to brush them off. The residual material after brushing will fall into the pellet collection box, mix with the pellets and is not easy to separate, which affects the pellet making efficiency.

[0005] Therefore, we need a pelleting machine to overcome the problems of residual materials being difficult to separate from the pellets and the poor heat dissipation of the pelleting machine. Utility Model Content

Each eccentric wheel is connected to the first shot rubbing roller shaft and the second shot rubbing roller shaft, respectively.

[0033] Example

[0034] like Figure 1-6 As shown, this utility model discloses a pellet making machine, including a housing 1 and a base 2. The housing 1 is mounted on the base 2. A heat dissipation component is provided on the outer side wall of the housing 1. The housing 1 is equipped with a feeding mechanism, an extrusion mechanism, and a pellet rolling mechanism. The feeding mechanism is located at the upper end of the housing 1, and the extrusion mechanism is located directly below the feeding mechanism. An extrusion module 3 is fixedly connected to one end of the extrusion mechanism that extends out of the housing 1. The extrusion module 3 can be replaced according to the actual pellet size requirements.

[0035] The pellet rolling mechanism is fixed on the base 2. A shaft knife 4 is provided at one end of the pellet rolling mechanism that extends out of the machine housing 1. A brush 5 is provided on one side of the shaft knife 4. A baffle 6 is provided directly below the brush 5. The rotation of the shaft knife 4 drives the brush 5 to rotate. The brush 5 is used to brush off the residual material on the shaft knife 4. The baffle 6 is used to collect the brushed-off residual material to prevent the residual material from mixing with the made pills, which would affect the quality of the pills and the pellet making efficiency.

[0036] The feeding mechanism includes a feeding hopper 7 and a stirring mechanism 8. The feeding hopper 7 is positioned directly above the stirring mechanism 8. The stirring mechanism 8 includes a first stirring shaft 9 and a second stirring shaft 10. Both the first stirring shaft 9 and the second stirring shaft 10 are equipped with stirring plates 11. A first gear 12 and a second gear 13 are respectively provided at one end of the first stirring shaft 9 and the second stirring shaft 10. The first gear 12 and the second gear 13 are meshed with each other. The extrusion mechanism includes a first motor 14, an extrusion shaft 15, a screw conveyor 16, an extrusion box 17, and a mounting plate 18. The mounting plate 18 is fixedly connected to the machine housing. The extrusion shaft 15 is fixed above the mounting plate 18 by a shaft seat. A third gear 19 is provided at one end of the extrusion shaft 15. The screw conveyor 16 passes through the extrusion box 17 and is close to the third gear 19 on the extrusion shaft 15. One end of the extrusion shaft 15 is connected to the first sprocket 20, and the output end of the first motor 14 is provided with the second sprocket 21. The first sprocket 20 and the second sprocket 21 are connected by the first chain 22. The third gear 19 is meshed with the first gear 12. The feed hopper 7 fixes the first stirring shaft 9 and the second stirring shaft 10 above the extrusion box 17. By starting the first motor 14, the second sprocket 21 and the first sprocket 20 are driven, which in turn causes the extrusion shaft 15 to drive the third gear 19 to rotate. Then the first gear 12 rotates, which drives the second gear 13 to rotate. The first stirring shaft 9 and the second stirring shaft 10 rotate relative to each other, finally completing the mixing and pressing of the material. The rotation of the extrusion shaft 15 drives the screw conveyor 16 to rotate, completing the material extrusion.

[0037] The first motor 14 is fixed on the base 2, and the extrusion box 17 is fixed on the mounting plate 18.

[0038] The shot-rolling mechanism includes a second motor 23, a third motor 24, a first shot-rolling roller shaft 26, a second shot-rolling roller shaft 27, a first rotating shaft 25, and a second rotating shaft 28. The second motor 23 is mounted on the base 2 via a motor fixing plate 29. The output end of the second motor 23 extending out of the motor fixing plate 29 is connected to a shot-rolling drive wheel 30. Two pairs of eccentric wheels 31 are mounted on the first rotating shaft 25, each eccentric wheel 31 being connected to the first shot-rolling roller shaft 26 and the second shot-rolling roller shaft 27 respectively. A shot-rolling driven wheel 42 is mounted on one end of the first rotating shaft 25 passing through the motor fixing plate 29. The shot-rolling drive wheel 30 and the shot-rolling driven wheel 42 are connected by a second chain 34. The output end of the third motor 24 is fixedly connected to the second rotating shaft 28. A fourth gear 32 and a fifth gear 33 are respectively mounted on the first shot-rolling roller shaft 26 and the second shot-rolling roller shaft 27. A sixth gear 43 is provided at one end of the second rotating shaft 28. The sixth gear 43 meshes with the fourth gear 32 and the fifth gear 33. When the third motor 24 is started, the second rotating shaft 28 rotates, and the sixth gear 43 rotates, causing the fourth gear 32 and the fifth gear 33 to rotate relative to each other. This ultimately drives the two shaft cutters 4 to rotate relative to each other, completing the shearing of the long strip of material. When the second motor 23 is started, the rubbing wheel drive wheel 30 drives the rubbing wheel driven wheel 42 to rotate, the first rotating shaft 25 rotates, and the two pairs of eccentric wheels 31 rotate, causing the first rubbing roller shaft 26 and the second rubbing roller shaft 27 to complete the axial reciprocating motion. That is, when the first rubbing roller shaft 26 extends forward, the second rubbing roller shaft 27 retracts backward synchronously, repeating the cycle. This drives the two shaft cutters 4 to reciprocate, thereby kneading the material segment between the rubbing grooves 401 of the shaft cutters and completing the rubbing operation.

[0039] The third motor 24 drives the second rotating shaft 28 to rotate. Through the meshing transmission of the sixth gear 43, the fourth gear 32, and the fifth gear 33, the two shaft cutters 4 rotate relative to each other, performing fixed-length shearing of the material strips. Simultaneously, the second motor 23 drives the first rotating shaft 25 to rotate through the rolling wheel drive wheel 30, the second chain 34, and the rolling wheel driven wheel 42, which in turn drives the two pairs of eccentric wheels 31 to rotate, causing the first and second rolling roller shafts 26 and 27 to perform synchronous reciprocating motions in opposite directions. Since the shaft cutters 4 and the rolling roller shafts are coaxially fixedly connected, the instant the shaft cutter 4 completes the shearing, the rolling groove 401 of the shaft cutter 4 immediately rolls the material segment into pellets. The cutting and rolling actions are synchronized through mechanical transmission.

[0040] The heat dissipation component includes heat dissipation holes 35 and a cooling fan 36. The heat dissipation holes 35 are evenly distributed on one side of the machine casing. The cooling fan 36 includes a fan body 37 and a mesh cover 38. By setting the heat dissipation holes 35 and the cooling fan 36, the internal parts of the pellet making machine are cooled, thereby improving the service life of the equipment.

[0041] Guide wheels 39 are provided above the two shaft cutters 4. The guide wheels 39 are fixed to the machine housing by the guide wheel fixing frame 40. The guide wheel fixing frame 40 is provided with a groove. The central shaft of the guide wheel 39 passes through the groove and is fixed on the guide wheel fixing frame 40. The guide wheel 39 can guide the extruded strip and prevent the extruded strip from swaying left and right, ensuring that the granular pills are smoothly cut and formed.

[0042] The brush 5 is mounted on the housing via the brush 5 mounting bracket.

[0043] A top cover 41 is provided on the top of the casing.

[0044] Therefore, this utility model adopts a pelleting machine with the above-mentioned structure: by setting a brush on one side of the shaft cutter, the material stuck in the groove of the shaft cutter can be brushed off to avoid affecting the pelleting effect. By setting a detachable baffle on one side of the brush, the brush brushes off the residual material stuck on the shaft cutter. The brushed-off material is collected in the baffle to avoid the residual material from mixing with the finished pellets, affecting the quality of the pellets and the pelleting efficiency.

[0045] By setting heat dissipation holes and cooling fans on the outer wall of the machine casing, the internal parts of the pellet making machine can be cooled quickly and effectively, thereby improving the service life of the equipment. Placing the cooling fans on the outside of the machine casing also facilitates maintenance and cleaning.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
