Description

Technical Field

[0001] This utility model belongs to the field of granulator technology, and specifically relates to a high-efficiency material conveying mechanism for granulators. Background Technology

[0002] A granulator is a molding machine that shapes materials into specific forms. It processes raw materials into granules or spheres through specific techniques to facilitate storage, transportation, and use.

[0003] Currently, Chinese utility model patent CN218908682U discloses a conveying device for a granulator. However, in existing granulators, material tends to accumulate inside the conveying mechanism during the conveying of finished material granules, causing blockages and affecting conveying efficiency. Furthermore, because the material processed by the granulator contains particles of uneven size, existing granulator conveying mechanisms cannot screen out smaller particles and discharge them through other outlets, thus limiting their practicality and affecting the quality of the finished granules. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency material conveying mechanism for a granulator, which has the advantages of screening and conveying out unqualified materials with small particle size and improving the conveying efficiency of material particles.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a high-efficiency material conveying mechanism for a granulator, comprising an upper conveying channel, a lower conveying channel fixedly connected to the bottom of the upper conveying channel, a separation net bolted between the upper and lower conveying channels, rotating cylinders rotatably connected to both the lower conveying channel and the interior of the motor, augers fixedly sleeved on the surfaces of the two rotating cylinders, synchronous pulleys bolted to the ends of the two rotating cylinders near the motor, synchronous belts drivenly sleeved on the surfaces of the synchronous pulleys, a motor bolted to one end of the upper conveying channel, and the output end of the motor bolted to the side of the synchronous pulley away from the rotating cylinder.

[0006] Using the above technical solution, the motor drives two rotating drums to rotate in the same direction. Smaller particles are screened into the lower conveying channel by a separating screen, and then discharged in opposite directions through the augers in the upper and lower conveying channels. This ensures the quality of the finished product and facilitates the collection of substandard materials. The rotating drums drive the feed inlet at the bottom of the agitator rod to mesh with the first conical gear, causing the agitator rod to rotate on the surface of the drum. This agitates the material particles in the upper and lower conveying channels, preventing particle accumulation and blockage, and improving the conveying efficiency.

[0007] The present invention is further configured such that: the interior of each of the two rotating cylinders is rotatably connected to a fixed rod welded to the interior of the upper conveying channel and the lower conveying channel respectively; a first bevel gear is fixedly sleeved on the surface of the fixed rod; a stirring rod is rotatably connected to the surface of the rotating cylinder; and a second bevel gear meshing with the first bevel gear is bolted to one end of the stirring rod near the interior of the rotating cylinder.

[0008] By adopting the above technical solution, the material particles inside the upper and lower conveying channels can be agitated to prevent them from accumulating and causing blockages, thereby improving the conveying efficiency of the material particles.

[0009] The present invention is further configured such that the augers inside the upper and lower conveying channels are installed on the surface of the rotating drum in opposite directions.

[0010] By adopting the above technical solution, the material particles inside the lower conveying channel can move in the opposite direction to the material particles inside the upper conveying channel, thereby being discharged from different outlets.

[0011] The present invention is further configured such that: a feed inlet is opened on the top side of the upper conveying channel near the motor, a first discharge port is opened on the bottom side of the feed inlet away from the motor, and a second discharge port is opened on the bottom side of the lower conveying channel near the motor.

[0012] Using the above technical solution, material particles are fed into the upper conveying channel through the inlet, and the material particles are discharged from the upper and lower conveying channels through the first and second discharge ports, respectively.

[0013] The present invention is further configured such that: the end of the feed inlet and the first discharge outlet that is away from the upper conveying channel, and the end of the second discharge outlet that is away from the lower conveying channel, are all threadedly connected with sealing caps.

[0014] By adopting the above technical solution, the inside of the feed inlet, the first discharge port, and the second discharge port can be sealed, thereby preventing dust from entering the interior when not in use.

[0015] The present invention is further configured such that a protective net for use with the motor is bolted to one end of the upper conveying channel near the motor.

[0016] The above technical solution provides ventilation and heat dissipation for the motor, while also isolating it from dust and impurities.

[0017] The present invention is further configured such that inspection doors are bolted to the top of the upper conveying channel and the bottom of the lower conveying channel.

[0018] The above technical solution facilitates the opening of the interior of the upper and lower conveying channels for maintenance and replacement of parts.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. By starting the motor, two rotating drums rotate in the same direction. Smaller particles are screened through a separating screen into the lower conveyor channel, and then conveyed out in opposite directions through the auger in the upper and lower conveyor channels respectively. This ensures the quality of the finished product and also facilitates the collection of substandard materials.

[0021] 2. The rotating drum drives the feed inlet at the bottom of the stirring rod to mesh with the first bevel gear, causing the stirring rod to rotate on the surface of the rotating drum. This stirs the material particles inside the upper and lower conveying channels, preventing the material particles from accumulating and causing blockages, and improving the conveying efficiency of the material particles.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 , Figure 2A high-efficiency material conveying mechanism for a granulator includes an upper conveying channel 1, with a lower conveying channel 2 fixedly connected to the bottom of the upper conveying channel 1. A separation screen 7 is bolted between the upper conveying channel 1 and the lower conveying channel 2. Rotating cylinders 4 are rotatably connected inside both the lower conveying channel 2 and the motor 3. Screws 5 are fixedly sleeved on the surfaces of the two rotating cylinders 4. Synchronous pulleys 16 are bolted to the ends of the two rotating cylinders 4 near the motor 3. Synchronous belts 6 are driven to the surfaces of the synchronous pulleys 16. The motor 3 is bolted to one end of the upper conveying channel 1, and the output end of the motor 3 is bolted to the side of the synchronous pulley 16 away from the rotating cylinders 4. By turning on the motor 3, the two rotating cylinders 4 rotate in the same direction. The material with smaller particle size is screened into the lower conveying channel 2 through the separation screen 7 and then conveyed and discharged in opposite directions inside the upper conveying channel 1 and the lower conveying channel 2 through the screws 5. This ensures the quality of the finished material granules and also facilitates the collection of unqualified materials.

[0029] refer to Figure 2 The augers 5 inside the upper conveying channel 1 and the lower conveying channel 2 are installed in opposite directions on the surface of the rotating drum 4. This allows the material particles inside the lower conveying channel 2 to move in the opposite direction to the material particles inside the upper conveying channel 1, thus being discharged from different outlets.

[0030] refer to Figure 1 , Figure 2 The upper conveying channel 1 has a feed inlet 11 on the top side near the motor 3, and a first discharge port 12 on the bottom side of the feed inlet 11 away from the motor 3. The lower conveying channel 2 has a second discharge port 13 on the bottom side near the motor 3. Material particles are fed into the upper conveying channel 1 through the feed inlet 11, and the material particles inside the upper conveying channel 1 and the lower conveying channel 2 are discharged through the first discharge port 12 and the second discharge port 13, respectively.

[0031] refer to Figure 2 The inlet 11 and the first outlet 12, located at the ends away from the upper conveying channel 1, and the second outlet 13, located at the ends away from the lower conveying channel 2, are all threaded with sealing caps 14. These caps can seal the interiors of the inlet 11, the first outlet 12, and the second outlet 13, thereby preventing dust from entering when the inlet is not in use.

[0032] Brief description of the operation: By turning on the motor 3, the synchronous belt 6 drives the two synchronous pulleys 16, which in turn drive the two rotating drums 4 to rotate in the same direction. Then, material particles are poured into the upper conveying channel 1, and the material particles are conveyed forward by the auger 5 inside the upper conveying channel 1. Afterwards, the material particles are screened and filtered by the separating screen 7, and the smaller particles fall into the lower conveying channel 2. Since the auger 5 inside the upper conveying channel 1 and the lower conveying channel 2 are in opposite directions, the rotating drum 4 will drive the plastic particles inside the lower conveying channel 2 to move to the other side, thus conveying the material particles out.

[0033] Example 2:

[0034] refer to Figure 1 , Figure 2 , Figure 3 A high-efficiency material conveying mechanism for a granulator is disclosed. Two rotating cylinders 4 each have a fixed rod 9 rotatably connected to the interior of an upper conveying channel 1 and a lower conveying channel 2, respectively. A first bevel gear 10 is fixedly sleeved on the surface of the fixed rod 9. A stirring rod 8 is rotatably connected to the surface of the rotating cylinder 4. A second bevel gear 18, meshing with the first bevel gear 10, is bolted to one end of the stirring rod 8 near the interior of the rotating cylinder 4. The rotating cylinder 4 drives the feed inlet 11 at the bottom of the stirring rod 8 to mesh with the first bevel gear 10, causing the stirring rod 8 to rotate on the surface of the rotating cylinder 4. This agitates the material particles inside the upper conveying channel 1 and the lower conveying channel 2, preventing the material particles from accumulating and causing blockages, thus improving the conveying efficiency of the material particles.

[0035] refer to Figure 1 , Figure 2 A protective net 15, which works in conjunction with the motor 3, is bolted to one end of the upper conveyor channel 1 near the motor 3. This net provides ventilation and heat dissipation for the motor 3 while also isolating it from dust and impurities.

[0036] refer to Figure 1 Inspection doors 17 are bolted to the top of the upper conveyor channel 1 and the bottom of the lower conveyor channel 2. This allows for easy opening of the interior of the upper conveyor channel 1 and the lower conveyor channel 2 for maintenance and replacement of parts.

[0037] Brief description of the operation: The motor 3 drives two rotating drums 4 to rotate inside the upper conveying channel 1 and the lower conveying channel 2. During this process, the rotating drums 4 drive the stirring rod 8 to rotate on the surface of the rotating drums 4. Then, the feed inlet 11 meshes with the first bevel gear 10, which is fixed to the surface of the fixed rod 9, so that the stirring rod 8 rotates on the surface of the rotating drums 4, agitating the material particles inside the upper conveying channel 1 and the lower conveying channel 2 to prevent blockage.
