Description

Technical Field

[0001] This utility model relates to the field of plastic product conveying technology, specifically a feeder for processing plastic products. Background Technology

[0002] Plastic products are products made primarily from plastics and are ubiquitous in modern life. Plastic is a material mainly composed of synthetic or natural polymer compounds that can be molded into a certain shape under certain temperature and pressure conditions and can maintain its shape at room temperature. The feeder for plastic product processing is a key piece of equipment in the plastic product production process. It is mainly used to transport plastic raw materials to the processing equipment at a certain rate. In the plastic product processing process, a stable supply of raw materials is the key to ensuring product quality and production efficiency.

[0003] However, existing technologies still have the following problems:

[0004] Firstly, large-scale plastic product production lines require the transportation of large quantities of plastic raw materials. To ensure a stable supply of raw materials during the processing of plastic products, production interruptions caused by blockages due to frequent feeding are common. Existing feeders on the market are not convenient for effectively and continuously feeding plastic raw materials, which seriously affects production efficiency.

[0005] Secondly, the processing of plastic products is crucial. It is necessary to precisely control the proportion of raw materials during the processing of plastic products in order to ensure the stability of product performance and quality. The existing feeders on the market are not convenient for precise control of the proportion of raw materials, and have low flexibility and adaptability.

[0006] To address the aforementioned problems, the inventors have proposed a feeding machine for processing plastic products. Utility Model Content

[0007] To address the problems of inconvenient and continuous feeding of plastic raw materials and inconvenient precise control of raw material ratios, the purpose of this utility model is to provide a feeder for processing plastic products.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: a feeding machine for processing plastic products, including a base plate, a metering device fixedly connected to the top surface of the base plate, a feeding device fixedly connected to the top surface of the base plate, the feeding device including two fixed rods, a housing fixedly connected to the top surface of the two fixed rods, swivel augers symmetrically and movably connected to one side of the housing, the outer surfaces of the two augers cooperating with each other, a protective box fixedly connected to one side of the housing, one end of each of the two augers rotatably connected to the inner wall of the protective box, the rotation of one auger will drive the other auger to rotate synchronously in the opposite direction, when the plastic raw material is added into the housing from the feeding funnel, the two augers rotating in the opposite direction cooperate with each other, since the gap between the outer surface of the auger and the housing is small, the feeding amount can be controlled more precisely, gears are fixedly sleeved on the outer surfaces of the two augers, the outer surfaces of the two gears mesh with each other, a first motor is fixedly connected to one side of the protective box, the output end of the first motor passes through the protective box and is fixedly connected to one side of the auger, and a feeding funnel is fixedly connected to the upper part of the outer surface of the housing.

[0009] Preferably, the metering device includes a bracket and a support rod. A storage tank is fixedly connected to one side of the bracket, and a conveying pipe is fixedly connected to the bottom of the storage tank. A second motor is fixedly connected to the top surface of the support rod, and a support plate is fixedly connected to the top surface of the second motor. A drive wheel is rotatably connected to one side of the top surface of the support plate. The output end of the second motor passes through the support plate and is fixedly connected to the bottom end of the drive wheel. A driven wheel is rotatably connected to the other side of the top surface of the support plate. A drive rod is fixedly connected to the outer surface of the drive wheel, and a rotating plate is fixedly connected to the top of the driven wheel. The top surface of the rotating plate has multiple through slots arranged in a circular array. The raw material in the storage tank will fall into the through slots through the conveying pipe under the action of gravity. Therefore, only one through slot can align with the conveying pipe and receive the raw material at a time. As the rotating plate rotates continuously, the inner wall of the through slot fits against the bottom end of the conveying pipe. The through slot and the conveying pipe are the same size.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model can achieve continuous feeding by having two augers rotating in opposite directions cooperate with each other. The rotation of the augers is like a screw conveyor, which pushes the plastic raw material to move in a specific direction during the rotation process.

[0012] 2. This utility model can drive the rotating plate to rotate synchronously by the rotation of the driven wheel. When the through groove rotates to the position aligned with the conveying pipe, the raw materials in the storage tank will fall into the through groove through the conveying pipe under the action of gravity, thereby achieving the purpose of accurately controlling the proportion of raw materials.

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 protection scope of the present utility model.

[0019] Example: Figure 1-3As shown, this utility model provides a feeder for processing plastic products, including a base plate 1. A metering device 3 is fixedly connected to the top surface of the base plate 1, and a feeding device 2 is fixedly connected to the top surface of the base plate 1. The feeding device 2 includes two fixed rods 21, and a housing 22 is fixedly connected to the top surface of the two fixed rods 21. The housing 22 has an elliptical cross-sectional shape. When the auger 23 rotates, the elliptical housing 22 can make the raw material flow more smoothly, reduce flow resistance, and improve feeding efficiency. A symmetrical through-hole connection is provided on one side of the housing 22. Screw 23, the outer surfaces of two screws 23 cooperate with each other, a protective box 24 is fixedly connected to one side of the housing 22, one end of each screw 23 is rotatably connected to the inner wall of the protective box 24, gears 25 are fixedly sleeved on the outer surfaces of both screws 23, and the outer surfaces of the two gears 25 mesh with each other, a first motor 26 is fixedly connected to one side of the protective box 24, the output end of the first motor 26 passes through the protective box 24 and is fixedly connected to one side of the screw 23, and a feed funnel 27 is fixedly connected to the upper part of the outer surface of the housing 22;

[0020] The rotation of the auger 23 is like a screw conveyor, continuously transporting raw materials from one end of the shell 22 to the other, thus enabling continuous feeding.

[0021] The metering device 3 includes a bracket 301 and a support rod 304. A storage tank 302 is fixedly connected to one side of the bracket 301. The lower part of the outer surface of the storage tank 302 is arc-shaped. A conveying pipe 303 is fixedly connected to the bottom end of the storage tank 302. The bottom ends of the bracket 301 and the support rod 304 are respectively fixedly connected to the top surface of the base plate 1. A second motor 305 is fixedly connected to the top surface of the support rod 304. A support plate 306 is fixedly connected to the top surface of the second motor 305. A drive wheel 307 is rotatably connected to one side of the top surface of the support plate 306. The output end of the second motor 305 passes through the support plate 306 and is fixedly connected to the bottom end of the drive wheel 307. A driven wheel 308 is rotatably connected to the other side of the top surface of the support plate 306. The outer surface of the drive wheel 307 is fixedly connected to the drive wheel 307. A drive rod 309 is fixedly connected, and the outer surface of the drive rod 309 is used to cooperate with the inner wall of the driven wheel 308. A rotating plate 310 is fixedly connected to the top of the driven wheel 308. The output end of the second motor 305 drives the drive wheel 307 to rotate. The drive rod 309 on the drive wheel 307 rotates together with the drive wheel 307. The outer surface of the drive rod 309 cooperates with the inner wall of the driven wheel 308. When the drive rod 309 rotates, it will intermittently drive the driven wheel 308 to rotate. The rotation of the driven wheel 308 drives the rotating plate 310 to rotate synchronously. The top surface of the rotating plate 310 is provided with multiple through slots 311 arranged in a ring array. The inner wall of the through slots 311 is in contact with the bottom end of the conveying pipe 303. The through slots 311 and the conveying pipe 303 are the same size.

[0022] The raw materials in the storage tank 302 will fall into the channel 311 through the conveying pipe 303 under the action of gravity. The channel 311 can be aligned with the conveying pipe 303 and receive the raw materials. As the rotating plate 310 rotates continuously, the proportion of raw materials can be precisely controlled.

[0023] Working principle: The first motor 26 is started, and its output drives one of the augers 23 to rotate. Since one end of both augers 23 is rotatably connected to the inner wall of the protective box 24, and both augers 23 have meshing gears 25 fixedly fitted onto their outer surfaces, the rotation of one auger 23 will drive the other auger 23 to rotate synchronously in the opposite direction. When the plastic raw material is added into the housing 22 from the feed hopper 27, the two counter-rotating augers 23 cooperate with each other. Because the gap between the outer surface of the auger 23 and the housing 22 is small, the feeding can be controlled relatively precisely. The material volume is controlled, and the material blockage during conveying is prevented. The cross-sectional shape of the shell 22 is elliptical. This shape design increases the internal space of the shell 22, accommodating more material. When the auger 23 rotates, the elliptical shell 22 allows the material to flow more smoothly, reducing flow resistance and improving feeding efficiency. During rotation, it pushes the plastic material to move in a specific direction. The rotation of the auger 23 is like a screw conveyor, continuously conveying the material from one end of the shell 22 to the other, thus achieving the purpose of continuous feeding.

[0024] The plastic raw material is first stored in storage tank 302. Because the lower part of the outer surface of storage tank 302 is arc-shaped, the raw material naturally converges towards the bottom conveying pipe 303 under gravity. The second motor 305 is then activated, and its output drives the drive wheel 307 to rotate. The drive rod 309 on the drive wheel 307 rotates along with it. The outer surface of the drive rod 309 engages with the inner wall of the driven wheel 308. When the drive rod 309 rotates, it intermittently drives the driven wheel 308 to rotate. The rotating plate 310 rotates synchronously. When the channel 311 rotates to the position aligned with the conveying pipe 303, the raw material in the storage tank 302 will fall into the channel 311 through the conveying pipe 303 under the action of gravity. Since the inner wall of the channel 311 is in contact with the bottom end of the conveying pipe 303, and the channel 311 and the conveying pipe 303 are the same size, only one channel 311 can be aligned with the conveying pipe 303 and receive the raw material at a time. As the rotating plate 310 rotates continuously, the purpose of accurately controlling the proportion of raw materials can be achieved.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
