Description

Technical Field

[0001] This utility model belongs to the field of feeding machine technology, and in particular relates to a spiral cooling feeding machine for processing plastic particles. Background Technology

[0002] In the plastics processing industry, the feeding and conveying of plastic particles is a key link connecting raw material processing and subsequent molding. Its conveying efficiency and particle integrity directly affect the overall production progress and product quality. As the plastics processing industry develops towards high efficiency and precision, traditional screw feeders have gradually revealed many problems that make them difficult to adapt to modern production needs.

[0003] Traditional screw feeders typically use a fixed, unidirectional motion pattern for the feeding pipe and screw blades. During the conveying process, plastic particles tend to aggregate and stack, making it difficult to disperse them fully. This results in uneven contact between the particles and the outside environment. Furthermore, freshly processed plastic particles often carry high residual heat, which is difficult to dissipate when aggregated, easily leading to adhesion and clumping. This not only causes blockage of the feeding pipe, affecting the continuity of the feeding process, but also damages the particle morphology, thereby affecting the product quality of subsequent injection molding, extrusion, and other processing steps. Therefore, a screw cooling feeder for plastic particle processing is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a spiral cooling feeder for processing plastic particles. By setting up a conveying assembly, specifically a drive unit that drives a rotating rod to rotate via a synchronous pulley set, the rotating rod drives a drive gear and a driven gear to mesh and transmit power, causing the conveying mechanism to rotate relative to each other. Simultaneously, a cooling module introduces cooling airflow into the support housing. The airflow fully contacts the particles through the feeding pipe, achieving synchronous cooling during the conveying process. This reduces the problem of particles sticking and clumping due to high temperatures. It solves the problem of traditional spiral feeders where the feeding pipe and spiral blades are mostly fixed and move in the same direction. This causes plastic particles to easily aggregate and stack during conveying, making it difficult to disperse them fully, resulting in uneven contact between the particles and the outside environment. Furthermore, freshly processed plastic particles often carry high residual heat, which is difficult to dissipate in an aggregated state, easily leading to adhesion and clumping. This not only causes blockage of the feeding pipe, affecting the continuity of the feeding process, but also damages the particle morphology, thus affecting the product quality of subsequent injection molding, extrusion, and other processing steps.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a spiral cooling feeder for processing plastic particles, comprising a supporting housing, a wind-cooling module fixedly connected to the top of the supporting housing, and a feeding mechanism mounted on the supporting housing. The feeding mechanism includes a conveying component mounted on the supporting housing and an auxiliary component mounted on the conveying component. The conveying component includes a feeding pipe rotatably connected to the inner wall of the supporting housing. A protective cover is fixedly connected to the left side of the outer surface of the supporting housing. A drive gear is disposed inside the cavity of the protective cover, and a driven gear is meshed with the outer surface of the drive gear. The inner ring of the driven gear is fixedly connected to the outer surface of the feeding pipe. A rotating rod is fixedly connected to the center of the drive gear, and a synchronous pulley set is fixedly connected to the outer surface of the rotating rod. A driving component is mounted on the protective cover. Several openings are provided on the left and right sides of the outer surface of the feeding pipe.

[0007] Furthermore, a feeding pipe is fixedly connected to the bottom left side of the support housing, a feeding hopper is fixedly connected to the top right side of the support housing, and a support frame is fixedly connected to the bottom of the outer surface of the support housing. The feeding pipe and the feeding hopper are respectively arranged corresponding to the opening.

[0008] Furthermore, the auxiliary component includes a triangular support block fixed to the inner wall of the protective cover. A mounting bracket is provided on the side of the triangular support block near the synchronous pulley set. A tensioning wheel is connected to the inner side of the mounting bracket via a pin. The outer ring of the tensioning wheel contacts the outer ring of the synchronous pulley set. The triangular support block is fixed to the protective cover by welding. Side lugs are fixedly connected to the left and right sides of the mounting bracket. A support rod is slidably connected to the center of each of the two side lugs.

[0009] Furthermore, the front of the two support rods is fixedly connected to the back of the triangular support block, and springs are sleeved on the outer surface of the two support rods, with the springs initially in a charged state.

[0010] Furthermore, the front sides of the two springs are fixedly connected to the back side of the triangular support block, and the sides of the two springs away from the triangular support block are respectively fixedly connected to the sides of the side ears close to the triangular support block.

[0011] Furthermore, the driving component includes a motor fixed to the left side of the protective cover, and a rotating shaft fixedly connected to the right output end of the motor via a coupling. The rotating shaft passes through the protective cover and the supporting housing and extends into the feeding tube cavity. The outer surface of the rotating shaft is rotatably connected to the interior of the protective cover and the supporting housing. A spiral blade is provided inside the feeding tube cavity. The outer ring of the spiral blade contacts the inner wall of the feeding tube, and the inner ring of the spiral blade is fixedly connected to the outer surface of the rotating shaft. The outer surface of the rotating shaft is fixedly connected to the side of the synchronous pulley assembly away from the rotating rod. The feeding tube and the spiral blade rotate relative to each other.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting up a conveying component, specifically, a drive unit drives a rotating rod to rotate via a synchronous belt pulley set. The rotating rod drives the active gear and the driven gear to mesh and transmit power, causing the conveying mechanism to rotate relative to each other. At the same time, the air-cooling module introduces cooling airflow into the support housing. The airflow fully contacts the particles through the feeding pipe, achieving synchronous cooling during the conveying process. This reduces the situation where particles stick together and clump due to high temperature, eliminating the need for additional cooling equipment, simplifying the production process, reducing costs, and improving the uniformity of particle conveying and the cooling effect of the relatively rotating conveying mechanism.

[0014] 2. This utility model, by setting a tensioning wheel, specifically, ensures that the spring always maintains a thrust on the tensioning wheel. The side lug pushes the mounting bracket to move along the support rod, so that the tensioning wheel continuously and tightly contacts the synchronous belt pulley set. When the synchronous belt pulley set becomes loose, the spring's thrust can automatically compensate for the gap, maintain the tension of the synchronous belt, reduce transmission slippage, ensure the transmission accuracy of the driving gear and driven gear, improve the stability and reliability of the feeder operation, extend the service life of transmission components, and reduce maintenance frequency.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1-5 As shown, this utility model is a spiral cooling feeder for processing plastic particles, including a supporting housing 111, with an air-cooling module 112 fixedly connected to the top of the supporting housing 111, and a feeding mechanism 2 mounted on the supporting housing 111. The feeding mechanism 2 includes a conveying assembly 21 mounted on the supporting housing 111 and an auxiliary assembly 22 mounted on the conveying assembly 21. The conveying assembly 21 includes a feeding pipe 213 rotatably connected to the inner wall of the supporting housing 111. A protective cover 211 is fixedly connected to the left side of the outer surface of the supporting housing 111. A drive gear 218 is provided inside the cavity of the protective cover 211. A driven gear 219 is meshed with the outer surface of the drive gear 218. The inner ring of the driven gear 219 is fixedly connected to the outer surface of the feeding pipe 213. A rotating rod 217 is fixedly connected to the center of the gear 218. A synchronous pulley set 216 is fixedly connected to the outer surface of the rotating rod 217. A driving component is installed on the protective cover 211. Several openings are provided on the left and right sides of the outer surface of the feeding pipe 213. The driving component drives the rotating rod 217 to rotate through the synchronous pulley set 216. The rotating rod 217 drives the driving gear 218 and the driven gear 219 to mesh and transmit power, so that the conveying mechanism rotates relative to each other. At the same time, the air-cooling module 112 introduces cooling airflow into the support housing 111. The airflow fully contacts the particles through the feeding pipe 213 to achieve synchronous cooling during the conveying process, reducing the situation of particles sticking and clumping due to high temperature. No additional cooling equipment is required, simplifying the production process and reducing costs. Moreover, the relatively rotating conveying mechanism improves the uniformity of particle conveying and the cooling effect.

[0026] A feeding pipe 113 is fixedly connected to the bottom left side of the support housing 111, a feeding hopper 114 is fixedly connected to the top right side of the support housing 111, and a support frame 115 is fixedly connected to the bottom of the outer surface of the support housing 111. The feeding pipe 113 and the feeding hopper 114 are respectively set to correspond to the opening.

[0027] Auxiliary component 22 includes a triangular support block 221 fixed to the inner wall of protective cover 211. A mounting bracket 222 is provided on the side of the triangular support block 221 near the synchronous pulley assembly 216. A tensioning wheel 223 is connected to the inner side of the mounting bracket 222 via a pin. The outer ring of the tensioning wheel 223 contacts the outer ring of the synchronous pulley assembly 216. The triangular support block 221 is fixed to the protective cover 211 by welding. Side lugs 224 are fixedly connected to the left and right sides of the mounting bracket 222. Support rods 225 are slidably connected to the center of each of the two side lugs 224. The front of each support rod 225 is fixedly connected to the back of the triangular support block 221. Springs 226 are fitted onto the outer surface of each support rod 225. The initial state of the springs 226 is a charged state. The front of the 6th gear is fixedly connected to the back of the triangular support block 221. The two springs 226, on the side away from the triangular support block 221, are fixedly connected to the side of the side ear 224 near the triangular support block 221. The springs 226 always maintain a thrust on the tension wheel 223. Through the side ear 224, the mounting bracket 222 is pushed to move along the support rod 225, so that the tension wheel 223 continuously and tightly contacts the synchronous belt pulley group 216. When the synchronous belt pulley group 216 becomes loose, the thrust of the springs 226 can automatically compensate for the gap, maintain the tension of the synchronous belt, reduce the occurrence of transmission slippage, ensure the transmission accuracy of the drive gear 218 and the driven gear 219, improve the stability and reliability of the feeder operation, extend the service life of the transmission components, and reduce the frequency of maintenance.

[0028] The driving component includes a motor 212 fixed on the left side of the protective cover 211. The output end of the motor 212 on the right side is fixedly connected to a rotating shaft 214 via a coupling. The rotating shaft 214 passes through the protective cover 211 and the supporting housing 111 and extends into the cavity of the feeding pipe 213. The outer surface of the rotating shaft 214 is rotatably connected to the inside of the protective cover 211 and the supporting housing 111. A spiral blade 215 is provided in the cavity of the feeding pipe 213. The outer ring of the spiral blade 215 contacts the inner wall of the feeding pipe 213. The inner ring of the spiral blade 215 is fixedly connected to the outer surface of the rotating shaft 214. The outer surface of the rotating shaft 214 is fixedly connected to the side of the synchronous pulley group 216 away from the rotating rod 217. The feeding pipe 213 and the spiral blade 215 rotate relative to each other.

[0029] A specific application of this embodiment is as follows: In use, the operator first pours the plastic particles to be conveyed into the feed hopper 114, then starts the motor 212 and the air-cooling module 112. The motor 212 drives the rotating shaft 214 to rotate through the coupling. The rotating shaft 214 drives the spiral blades 215 to rotate in the cavity of the feeding pipe 213, and also drives the synchronous pulley set 216 to rotate. The synchronous pulley set 216 drives the drive gear 218 to rotate through the rotating rod 217. The drive gear 218 meshes with the driven gear 219 to drive the feeding pipe. 213 rotates on the inner wall of the support housing 111, and the feeding pipe 213 and the spiral blade 215 rotate relative to each other, so that the plastic particles are introduced from the opening corresponding to the feeding hopper 114 and pushed to the left. At the same time, the air-cooling module 112 continuously introduces cooling air into the support housing 111. The airflow cools the material inside the feeding pipe 213 and makes full contact with the dispersed plastic particles to achieve synchronous cooling during the conveying process, so as to avoid the particles from sticking and clumping due to high temperature. The cooled plastic particles are finally discharged from the discharge pipe 113 to meet the subsequent processing requirements.

[0030] During equipment operation, auxiliary component 22 always plays a tensioning role. Spring 226 is initially in a stored state and always maintains a thrust on tension wheel 223. Through side lug 224, it pushes mounting bracket 222 to move along support rod 225 towards synchronous pulley group 216, so that tension wheel 223 continuously and tightly fits the outer ring of synchronous pulley group 216. When synchronous pulley group 216 becomes loose due to long-term operation, the thrust of spring 226 can automatically compensate for the loose gap, maintain the tension of synchronous belt, avoid slippage during transmission, ensure the transmission accuracy of drive gear 218 and driven gear 219, and thus ensure the rotation coordination of feed pipe 213 and spiral blade 215, improve the stability and reliability of feeder operation, extend the service life of transmission components, and reduce maintenance frequency.

[0031] It should be noted that the control of the motor 212 and the air-cooling module 112 in this application can be achieved by using the program set in the control panel and inputting relevant parameters as needed for automated control. This control method can be achieved using existing technologies, such as PLC.

[0032] The air-cooled module 112 generates airflow through a built-in fan, continuously supplying cooling air into the support housing 111. The airflow comes into full contact with the plastic particles during the conveying process through the feeding pipe 213, quickly removing heat from the particle surface and reducing the particle temperature, thus solving the problem of high-temperature particles sticking and clumping at the source.

[0033] Adaptable to conveying rhythm: The wind speed and air volume can be adjusted according to parameters such as the conveying volume and initial temperature of plastic particles. It supports automatic control or manual adjustment to ensure that the cooling effect matches the conveying rhythm, ensuring uniform cooling of particles and avoiding energy waste caused by over-cooling.

[0034] Protection and adaptability: The module shell adopts a temperature-resistant and dustproof design, which can adapt to the working environment of the plastic processing workshop and prevent dust from entering the module and affecting the stability of operation; its installation position is precisely matched with the support shell 111, without interfering with the feeding operation of the feed hopper 114 and the rotation operation of the feeding pipe 213.
