Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, and specifically to a feeding device for plastic production that prevents clogging. Background Technology

[0002] In plastics production, the feeding device is an automated or semi-automated system used to accurately and efficiently transport raw materials (such as resin granules, additives, masterbatches, etc.) to processing equipment (such as injection molding machines, extruders, blow molding machines, etc.). Its core function is to ensure the precise proportioning and continuous supply of raw materials during the production process and to reduce contamination, thereby improving production efficiency and product quality. The clogging problem of existing feeding devices is one of the main pain points affecting production efficiency and increasing maintenance costs.

[0003] A search revealed a utility model patent with publication number CN221968630U, which discloses a quantitative feeding device for plastic machines. This device relates to the field of quantitative feeding technology for plastic machines. It includes a feeding rack, a storage bin fixedly connected to the top of the feeding rack, a cover movably connected to the top of the storage bin, an anti-clogging component fixedly connected to the top of the cover and extending through both ends of the storage bin, a feeding bin fixedly connected to the bottom upper surface of the feeding rack, an electric push rod fixedly connected to the left outer wall of the feeding rack, a telescopic component on the left end of the clamping plate, a storage box on the inner wall of the U-shaped plate, and a conveying pipe fixedly connected to the top right side of the feeding bin, extending to the bottom of the storage bin. This utility model moves the quantitative component below the connecting groove, feeds the raw material from the storage bin into the quantitative component via the conveying pipe, moves the quantitative component to the bottom of the outlet, and then conveys the material into the storage box for storage.

[0004] The aforementioned patent only uses a motor to drive a threaded rod to unclog the raw materials. However, during production, the unclogging effect may be reduced due to the different forms of the raw materials, resulting in blockage.

[0005] Therefore, it is necessary to invent a feeding device for plastic production that prevents clogging in order to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a feeding device for plastic production that prevents clogging. By using a motor to drive a variable pitch screw with different thread edge distances, the device increases the friction of the raw material in the upper layer and reduces the extrusion of the raw material in the lower layer, thereby reducing the risk of raw material clogging. At the same time, an ion blower and a high-pressure nozzle are used to pulse and blow high-pressure air onto the raw material, which breaks up the arch structure of the material accumulation. Meanwhile, the ion flow in the ion blower neutralizes the charge in the raw material, thus solving the problem of production efficiency caused by raw material clogging in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for plastic production that prevents clogging, comprising a support plate, a discharge bucket fixedly connected to the upper end of the support plate, a storage bucket fixedly connected to the upper end of the discharge bucket, the discharge bucket communicating with the interior of the storage bucket, an inlet fixedly connected to the upper end of the storage bucket, the inlet communicating with the interior of the storage bucket, an electric actuator fixedly connected to the upper end of the support plate, a connecting rod rotatably connected to the output end of the electric actuator, the connecting rod rotatably connected to the lower end of the support plate, two discharge openings slidably connected to the lower end of the support plate, a connecting rod 2 and a connecting rod 3 rotatably connected to the lower end of the support plate, the ends of the connecting rod 2 and the connecting rod 3 engaging, the sidewalls of the connecting rod 1 and the connecting rod 2 rotatably connected to the sidewall of one of the discharge openings, and the sidewall of the connecting rod 3 rotatably connected to the sidewall of the other discharge opening.

[0008] Preferably, a connecting plate is fixedly connected to the side wall of the discharge hopper, a motor is fixedly connected to the lower end of the connecting plate, a pulley is fixedly connected to the output end of the motor through a coupling, a synchronous belt is sleeved on the outside of the pulley, a variable pitch screw is rotatably connected inside the storage hopper, a pulley is fixedly connected to the side wall of the variable pitch screw, and the synchronous belt is sleeved on the outside of the pulley.

[0009] Preferably, an ion fan is fixedly connected to the lower end of the connecting plate, a connecting pipe is fixedly connected to the output end of the ion fan, two spiral tubes are fixedly connected to the end of the connecting pipe, the connecting pipe communicates with the interior of the spiral tubes, multiple high-pressure nozzles are fixedly connected to the side walls of the two spiral tubes, the high-pressure nozzles communicate with the interior of the spiral tubes, and the high-pressure nozzles communicate with the interior of the storage tank.

[0010] Preferably, a dustproof box is fixedly connected to the side wall of the input end of the ion fan.

[0011] Preferably, a filter plate is slidably connected inside the dustproof box, and a filter cotton core is detachably connected inside the filter plate.

[0012] Preferably, the lower end of the support plate is fixedly connected to multiple support columns.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. Raw materials are poured in through the feed inlet and enter the storage and discharge bins. When production discharge is required, the electric push rod is driven. The electric push rod extends and drives the first connecting rod to rotate. The rotation of the first connecting rod causes one of the discharge openings to slide. The sliding of the discharge opening causes the second connecting rod to rotate. The rotation of the second connecting rod causes the third connecting rod to rotate. The rotation of the third connecting rod causes the other discharge opening to slide. At this time, the raw materials flow out through the lower opening of the discharge bin for subsequent production. When quantitative discharge is required, pressure sensors are installed at the upper ends of the two discharge openings. The device can automatically drive the electric push rod to extend and open the two discharge openings for discharge. When the pressure sensors at the upper ends of the two discharge openings detect that the pressure has decreased to a certain amount, the electric push rod is automatically driven to retract and close the two discharge openings for quantitative discharge.

[0015] 2. During material feeding, the drive motor rotates, causing pulley one to rotate. Under the action of the synchronous belt, pulley one rotates, causing pulley two to rotate, which in turn drives the variable pitch screw to rotate. The rotation of the variable pitch screw causes the raw material to flow continuously downwards. The variable pitch screw has different helix distances; the upper layer has denser threads, increasing the friction of the raw material, while the lower layer has looser threads, reducing material compression and lowering the risk of material blockage. At specified intervals, the device automatically drives the ion blower, which draws in air and pumps it into the connecting pipe. The air then enters two surrounding pipes, then into the high-pressure nozzle, and finally is ejected from the high-pressure nozzle. The high-pressure airflow breaks up the arch bridges of material accumulation, preventing material buildup and reduced production efficiency. At the same time, the ion flow in the ion blower neutralizes the charge generated by the material's flow and friction, preventing the material from accumulating due to static electricity and causing blockage.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-5The illustrated feeding device for plastic production, designed to prevent clogging, includes a support plate 001. A discharge hopper 101 is fixedly connected to the upper end of the support plate 001. A storage hopper 102 is fixedly connected to the upper end of the discharge hopper 101, and the discharge hopper 101 communicates with the interior of the storage hopper 102. An inlet 103 is fixedly connected to the upper end of the storage hopper 102, communicating with the interior of the storage hopper 102. An electric actuator 401 is fixedly connected to the upper end of the support plate 001, and the output end of the electric actuator 401 is rotatably connected to… There is a connecting rod 402, which is rotatably connected to the lower end of the support plate 001. The lower end of the support plate 001 is slidably connected to two discharge openings 403. The lower end of the support plate 001 is rotatably connected to a connecting rod 404 and a connecting rod 405. The ends of the connecting rods 404 and 405 are engaged. The sidewalls of the connecting rods 402 and 404 are rotatably connected to the sidewalls of one of the discharge openings 403, and the sidewalls of the connecting rods 405 are rotatably connected to the sidewalls of the other discharge opening 403. Raw materials are poured in through inlet 103 and enter the storage bin 102 and discharge bin 101. When production discharge is required, the electric push rod 401 is driven. The electric push rod 401 extends and drives the connecting rod 1 402 to rotate. The rotation of the connecting rod 1 402 causes one of the discharge openings 403 to slide. The sliding of the discharge opening 403 causes the connecting rod 2 404 to rotate. The rotation of the connecting rod 2 404 causes the connecting rod 3 405 to rotate. The rotation of the connecting rod 3 405 causes the other discharge opening 403 to slide. At this time, the raw materials flow out through the lower opening of the discharge bin 101 for subsequent production. When quantitative discharge is required, pressure sensors are installed at the upper ends of the two discharge openings 403. The device can automatically drive the electric push rod 401 to extend and open the two discharge openings 403 for discharge. When the pressure sensors at the upper ends of the two discharge openings 403 detect that the pressure has decreased to a certain amount, the electric push rod 401 is automatically driven to retract and close the two discharge openings 403 for quantitative discharge.

[0026] A connecting plate 104 is fixedly connected to the side wall of the discharge hopper 101. A motor 201 is fixedly connected to the lower end of the connecting plate 104. A pulley 202 is fixedly connected to the output end of the motor 201 via a coupling. A synchronous belt 203 is sleeved on the outside of the pulley 202. A variable pitch screw 205 is rotatably connected inside the storage hopper 102. A pulley 204 is fixedly connected to the side wall of the variable pitch screw 205. The synchronous belt 203 is sleeved on the outside of the pulley 204. During material discharge, the motor 201 is driven. The motor 201 is a servo motor. The motor, model 1FL6044, rotates at the output end of motor 201, driving pulley 202 to rotate. Under the action of synchronous belt 203, pulley 202 rotates, driving pulley 204 to rotate. Pulley 204 rotates, driving variable pitch screw 205 to rotate. The rotation of variable pitch screw 205 causes the raw material to flow continuously downward. The variable pitch screw 205 has different helical edge distances. The upper layer has denser threads, increasing the friction of the raw material, while the lower layer has looser threads, reducing the extrusion of the raw material and lowering the risk of material blockage.

[0027] An ion fan 301 is fixedly connected to the lower end of the connecting plate 104. A connecting pipe 302 is fixedly connected to the output end of the ion fan 301. Two surrounding pipes 303 are fixedly connected to the end of the connecting pipe 302. The connecting pipe 302 connects to the inside of the surrounding pipes 303. Multiple high-pressure nozzles 304 are fixedly connected to the side walls of the two surrounding pipes 303. The high-pressure nozzles 304 connect to the inside of the surrounding pipes 303 and the inside of the storage tank 102. At a specified time, the device automatically drives the ion fan 301 to draw in the air and pump it into the connecting pipe 302. The air then enters the two surrounding pipes 303 through the connecting pipe 302, and then enters the high-pressure nozzles 304 through the surrounding pipes 303. Finally, the air is ejected through the high-pressure nozzles 304. The high-pressure airflow breaks up the arch bridge of the material accumulation, preventing the raw material from accumulating and reducing production efficiency. At the same time, the ion flow in the ion fan 301 neutralizes the charge generated by the material due to flow and friction, preventing the material from accumulating due to static electricity and causing the device to become blocked.

[0028] A dustproof box 305 is fixedly connected to the side wall of the input end of the ion fan 301. When the motor 201 starts, the air drawn in enters the input end of the ion fan 301 through the dustproof box 305.

[0029] A filter plate 306 is slidably connected inside the dust box 305. A filter cotton core 307 is detachably connected inside the filter plate 306. After air enters the dust box 305, it is filtered by the filter cotton core 307 inside the filter plate 306 and then enters the ion fan 301. Finally, the material is sprayed to prevent dust from entering the discharge hopper 101 and contaminating the raw materials, thereby affecting subsequent production.

[0030] Multiple support columns 105 are fixedly connected to the lower end of the support plate 001. The multiple support columns 105 support the device and ensure the stability of the device during operation.

[0031] The working principle of this utility model is as follows: Raw materials are poured in through the feed inlet 103 and enter the storage bin 102 and the discharge bin 101. When production unloading is required, the electric actuator 401 is driven. The electric actuator 401 extends, causing the connecting rod 402 to rotate. The rotation of the connecting rod 402 causes one of the discharge openings 403 to slide. The sliding of the discharge opening 403 causes the connecting rod 404 to rotate. The rotation of the connecting rod 404 causes the connecting rod 405 to rotate. The rotation of the connecting rod 405 causes the other discharge opening to rotate. When the material outlet 403 slides, the raw material flows out through the lower opening of the discharge bucket 101 for subsequent production. When quantitative feeding is required, pressure sensors are installed at the upper ends of the two discharge outlets 403. The device can automatically drive the electric push rod 401 to extend and open the two discharge outlets 403 for feeding. When the pressure sensors at the upper ends of the two discharge outlets 403 detect that the pressure has decreased to a certain amount, they automatically drive the electric push rod 401 to retract and close the two discharge outlets 403 for quantitative feeding.

[0032] During material feeding, drive motor 201 (servo motor, model 1FL6044) rotates, driving pulley 202 to rotate. Under the action of synchronous belt 203, pulley 202 drives pulley 204 to rotate, which in turn drives variable pitch screw 205 to rotate. The rotation of variable pitch screw 205 ensures the continuous downward flow of raw material. The variable pitch screw 205 has different helix pitches; the upper layer has denser threads to increase friction on the raw material, while the lower layer has looser threads to reduce material compression. To minimize the risk of raw material blockage, the device automatically drives the ion fan 301 at specified intervals. The ion fan 301 draws in air and pumps it into the connecting pipe 302. The air then enters two surrounding pipes 303, and finally passes through the surrounding pipes 303 into the high-pressure nozzle 304. The high-pressure airflow is then ejected from the high-pressure nozzle 304. The ejected high-pressure airflow breaks up the arch bridges formed by the accumulation of materials, preventing raw material buildup and reduced production efficiency. At the same time, the ion flow in the ion fan 301 neutralizes the charge generated by the flow and friction of the raw materials, preventing the accumulation of raw materials due to static electricity and thus preventing blockage of the device.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
