The outer side of the feeding device is rotatably connected to the inner side of the feeding shell.

Description

TECHNICAL FIELD

[0001] The present application relates to the conveying technical field, specifically relates to a conveying system for plastic particle processing production. BACKGROUND

[0002] In the field of plastic particle processing production, the material conveying link is a key part in the whole production process, and its conveying efficiency and stability are crucial to guarantee product quality and production continuity. Traditional plastic particle conveying devices often have many deficiencies and are difficult to meet the increasingly diversified and refined production process requirements.

[0003] In the prior art, plastic particles are prone to uneven feeding, clogging and other problems during feeding. Common feeding devices only rely on simple gravity feeding method, and lack effective mechanisms to ensure that the material can enter the conveying pipe or conveying housing with stable and appropriate flow. Once the material is agglomerated, bridged or the like, the feeding will be interrupted, affecting the subsequent conveying work, that is, either the conveying device is idle due to insufficient feeding, wasting energy and affecting production progress, or the conveying system is paralyzed due to excessive feeding, causing great disturbance to production. SUMMARY

[0004] In view of the deficiencies of the prior art, the technical scheme adopted by the present application to solve its technical problems is: a conveying system for plastic particle processing production, comprising: a base, a feeding shell is fixedly connected to the top of the base, a feeding device is fixedly connected to the top of the feeding shell, a driving motor is fixedly connected to the outer side of the feeding shell, a feeding device is fixedly connected to the output end of the driving motor, and the outer side of the feeding device is rotatably connected to the inner side of the feeding shell; a dust suction device is used to absorb dust generated during feeding of the feeding device, the outer side of the dust suction device is fixedly connected to the inner side of the base, and the top of the dust suction device is fixedly connected to the top of the feeding shell. The base serves as a support structure, and the feeding shell fixedly connected thereto constitutes a main frame. The feeding shell cooperates with the feeding device, the driving motor, the feeding device and the dust suction device to work together to complete the functions of feeding, conveying and dust absorption and purification of plastic particles.

[0005] The feeding device includes a feeding hopper, a limiting shell fixedly connected to the outer side of the feeding hopper, a discharge pipe slidably connected to the inner wall of the feeding hopper, a support rod fixedly connected to the top of the discharge pipe, a conical sealing block fixedly connected to the top of the support rod, a unclogger fixedly connected to the top of the conical sealing block, a slider fixedly connected to the outer side of the discharge pipe, a guide rod fixedly connected to the top of the slider, and a compression spring provided on the outer side of the guide rod. When the slider is subjected to the upward pushing force of the top block, it will slide upward within the limiting shell, simultaneously driving the entire discharge pipe to move upward. At this time, the compression spring on the outer side of the guide rod is compressed, and the support rod drives the conical sealing block to move upward, allowing the material added to the feeding hopper to flow smoothly into the discharge pipe.

[0006] The feeding device includes a rotating shell, a scraper assembly fixedly connected to the outer side of the rotating shell, a telescopic cylinder fixedly connected to the inner side of the rotating shell, a sliding rod fixedly connected to the output end of the telescopic cylinder, a fixed ring fixedly connected to the outer side of the sliding rod, a limit plate slidably connected to the outer side of the fixed ring, a rotating rod fixedly connected to the outer side of the limit plate, a fixed sleeve rotatably connected to the outer wall of the rotating rod, and a feeding plate fixedly connected to the outer side of the rotating rod. The telescopic cylinder can extend and retract as needed, driving the fixed ring to move via the sliding rod, thereby causing the limit plate to slide along the fixed ring, thus changing the angle of the rotating rod relative to the fixed sleeve, and ultimately adjusting the tilt angle of the feeding plate.

[0007] Preferably, the outer side of the rotating shell is fixedly connected to the output end of the drive motor, the outer side of the scraping assembly is fixedly connected to the inner wall of the feeding shell, the outer side of the fixing sleeve is fixedly connected to the inner wall of the rotating shell, and the feeding plates are arranged in a ring along the central axis of the rotating shell. When the rotating shell rotates, the feeding plates rotate accordingly, and the plastic particles located in the feeding shell move along the axial direction of the feeding shell by means of centrifugal force and friction.

[0008] Preferably, the scraping assembly includes a rotating ring, with a baffle plate rotatably connected to the outer side of the rotating ring. The baffle plate primarily provides structural support for the feeding device and provides stable axial positioning for the rotating ring, ensuring the stability of the entire rotating shell and its connected components during operation. An arc-shaped scraper is fixedly connected to the outer side of the rotating ring, and a top block is fixedly connected to the side of the rotating ring away from the arc-shaped scraper. The rotation of the rotating ring drives the arc-shaped scraper to perform a circular motion, pushing the material along the inner wall of the feeding shell towards the discharge direction. This effectively prevents material accumulation inside the feeding shell.

[0009] Preferably, the inner side of the rotating ring is fixedly connected to the outer side of the rotating shell, the outer side of the baffle plate is fixedly connected to the inner wall of the feeding shell, the outer side of the arc-shaped scraper is slidably connected to the inner wall of the feeding shell, and the outer side of the top block is in contact with the bottom of the slider. The top block periodically applies an upward pushing force to the slider, so that the particles in the feed pipe can fall into the feeding shell evenly with a certain rhythm and flow rate.

[0010] Preferably, the bottom of the feeding hopper is fixedly connected to the top of the feeding shell, the side wall of the conical sealing block is in contact with the inner wall of the feeding hopper, the outer side of the slider is slidably connected to the inner wall of the limiting shell, and the top of the limiting shell is slidably connected to the outer wall of the guide rod. When the top block pushes the slider upward, the slider drives the conical sealing block to move upward through the support rod, and at this time the unblocking frame also moves upward in a straight line.

[0011] Preferably, the top end of the compression spring is fixedly connected to the top end of the limiting shell, the bottom end of the compression spring is fixedly connected to the top end of the slider, and the bottom end of the limiting shell is fixedly connected to the top end of the feeding shell. During the movement of the unblocking frame, its agitation and pushing effect on the particles can make the particles fall more orderly towards the direction of the feeding pipe.

[0012] Preferably, the dust collection device includes an air inlet duct, a rotating shaft rotatably connected to the inner side of the air inlet duct, fan blades fixedly connected to the outer wall of the rotating shaft, a ventilation frame fixedly connected to the top of the air inlet duct, and a vent pipe fixedly connected to the outer side of the air inlet duct. A filter assembly is fixedly connected to the top of the vent pipe, and a suction shell is fixedly connected to the bottom of the filter assembly. The rotation of the fan blades agitates the air inside the air inlet duct, thereby creating a negative pressure area inside the air inlet duct. At this time, the feeding shell is filled with dust-laden air generated during the conveying of plastic particles, which is then sucked in through the suction shell under the action of the pressure difference. The suction shell covers a certain area above the feeding shell, effectively collecting the dust-laden air raised during feeding and other operations. The dust-laden air sucked in by the suction shell then enters the filter assembly connected to it, so that most of the dust is trapped in the filter assembly. The air after preliminary filtration continues to flow along the vent pipe, which serves as a connecting channel to transport this part of the air with reduced dust content to the air inlet duct.

[0013] Preferably, the outer side of the air inlet duct is fixedly connected to the inner side of the base, the outer side of the rotating shaft is rotatably connected to the output end of the drive motor via a pulley set, the bottom of the suction shell is fixedly connected to the top of the feeding shell, and the top of the air inlet duct is fixedly connected to the bottom of the feeding shell. The airflow entering the air inlet duct is blown upwards into the feeding shell through the ventilation frame. Since the airflow direction is from bottom to top, an upward airflow disturbance is formed inside the feeding shell. Dust generated and settled at the bottom of the feeding shell or attached to the wall during the conveying of plastic granules is easily blown up again and suspended in the air under the action of this upward airflow.

[0014] Preferably, the filter assembly includes a fixed cylinder, a knob threadedly connected to the outer side of the fixed cylinder, a push rod rotatably connected to the outer side of the knob, a filter cylinder slidably connected to the inner side of the fixed cylinder, a return spring fixedly connected to the inner side of the fixed cylinder, and a sliding ring fixedly connected to the outer side of the return spring. When the operator manually rotates the knob, the knob will move spirally along the outer wall of the fixed cylinder. At this time, the push rod will move away from the filter cylinder along the radial direction of the fixed cylinder. This process gradually releases the squeezing effect of the push rod on the filter cylinder.

[0015] Preferably, the bottom of the fixed cylinder is fixedly connected to the top of the suction shell, the outer side of the push rod is in contact with the outer side of the filter cylinder, the side of the filter cylinder away from the push rod is in contact with the outer side of the sliding ring, the outer side of the sliding ring is slidably connected to the inner wall of the fixed cylinder, and the outer side of the fixed cylinder is fixedly connected to the top of the vent pipe. When the elastic potential energy stored in the return spring, which was originally in a compressed state, begins to be released, under the action of the elastic force, the return spring will push the sliding ring connected to it to slide outward along the inner wall of the fixed cylinder. The sliding of the sliding ring will apply an outward thrust to the filter cylinder, causing the filter cylinder to gradually move from the internal space of the fixed cylinder to the outside.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. This invention, by incorporating a feeding device, allows the telescopic cylinder to extend and retract as needed. A sliding rod drives a fixed ring to move, causing a limiting plate to slide along the fixed ring. This changes the angle of the rotating rod relative to the fixed sleeve, ultimately adjusting the tilt angle of the feeding plate. By adjusting the tilt angle of the feeding plate, parameters such as the conveying speed, pushing force, and conveying volume of plastic granules within the feeding shell can be altered to adapt to different production process requirements and material conveying conditions.

[0018] 2. This invention incorporates a baffle plate, whose primary function is to provide structural support for the feeding device. It provides stable axial positioning for the rotating ring, ensuring the stability of the entire rotating shell and its connected components during operation. Simultaneously, the baffle plate's structural design includes a reserved space, allowing material to pass through its bottom. During feeding, after the plastic granules fall from the feeding device into the feeding shell, they can continue moving towards the discharge direction along the space between the bottom of the baffle plate and the inner wall of the feeding shell. The presence of the baffle plate does not obstruct the normal material conveying process, ensuring a smooth material conveying path.

[0019] 3. This invention, by incorporating an arc-shaped scraper, causes the scraper to rotate in a circular motion as the plastic granules fall from the feed pipe into the feeding shell. This pushes the material along the inner wall of the feeding shell towards the discharge direction. This effectively prevents material from accumulating inside the feeding shell, especially in the critical area below the feed pipe where accumulation is likely to occur. By continuously guiding and pushing the material, good flowability is maintained within the feeding shell, ensuring that the feeding device can continuously and efficiently transport the plastic granules to the next production stage.

[0020] 4. This invention incorporates a rotating ring. During the rotation of the ring, the top block moves in a circular motion. Whenever the top block reaches the contact position with the slider, its continuous circular motion generates an upward pushing force on the slider. As the connecting component of the feed pipe, the slider, under the upward pushing force from the top block, slides upward within the limiting shell, simultaneously causing the entire feed pipe to move upward. At this time, the compression spring on the outside of the guide rod is compressed, causing the support rod to move the conical sealing block upward, allowing the material added to the feed hopper to flow smoothly into the feed pipe.

[0021] 5. This invention applies an upward pushing force to the slider periodically by a top block. As the motor speed increases, the top block's up-and-down movement accelerates, increasing the feed flow rate. This matches the changing conveying capacity of the feeding device. With the increased rotational speed of the rotating shell, the feeding plate in the feeding device enhances its material-pushing ability, enabling it to convey material more quickly along the feeding shell towards the discharge direction. The increased feed flow rate resulting from the accelerated up-and-down movement of the top block provides sufficient material to the feeding device, ensuring that it does not run dry and maintains a dynamic balance between the feeding and conveying stages.

[0022] 6. This invention utilizes a hopper-like structure. The top block on the rotating ring rotates in a circular motion and periodically contacts the slider. When the top block pushes the slider upwards, the slider, via the support rod, moves the conical sealing block upwards, causing the hopper-like structure to move upwards in a straight line. When the top block disengages from the slider, the hopper-like structure moves downwards under the force of the compression spring. This cycle repeats, causing the hopper-like structure to move up and down periodically within the feed hopper. During this movement, the agitation and pushing action of the hopper-like structure helps the particles fall more orderly towards the discharge pipe.

[0023] 7. This invention incorporates a dust collection device. When the drive motor starts and powers the feeding device, it also drives the rotating shaft via a pulley assembly, causing the fan blades fixed to the outer wall of the shaft to rotate. The rotation of the fan blades agitates the air inside the air inlet, creating a negative pressure zone. At this time, the feeding housing is filled with dust-laden air generated during the conveying of plastic granules. Under the pressure difference, this air is drawn in through the suction housing, which covers a certain area above the feeding housing, effectively collecting the dust-laden air generated during feeding and other operations.

[0024] 8. This invention, by incorporating a dust collection device, directs airflow into the inlet duct via a ventilation frame, blowing it upwards into the feeding shell. This upward airflow creates an upward turbulence within the feeding shell. Dust generated during plastic granule conveying and settling at the bottom of the feeding shell or adhering to the walls is easily re-blown up and suspended in the air by this upward airflow. Meanwhile, the suction shell maintains a negative pressure, drawing in the suspended dust again, which then enters the filter assembly for another round of filtration and collection. This cycle repeats continuously. Inside the feeding shell, the upward airflow created by the ventilation frame continuously blows up newly generated dust and previously incompletely collected dust, drawing it into the dust collection system. The filter assembly then effectively intercepts and collects the dust, ensuring that the dust inside the feeding shell is collected as thoroughly as possible. This achieves the goals of purifying the air inside the feeding shell, reducing dust pollution, and preventing dust from mixing with plastic granules and affecting product quality.

[0025] 9. This invention, through the design of a filter assembly, allows the operator to manually rotate a knob when the filter cartridge needs to be disassembled for cleaning, replacement, or maintenance. This gradually releases the pressure exerted on the filter cartridge by the push rod. During this process, the elastic potential energy stored in the previously compressed return spring is released, causing the filter cartridge to gradually move from the interior of the fixed cylinder to the outside, thus allowing the filter cartridge to be removed from the fixed cylinder.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0038] Example: Please refer to Figure 1 - Figure 10 This invention provides a technical solution: a conveying system for processing and producing plastic granules, comprising:

[0039] The base 1 has a feeding shell 2 fixedly connected to its top, a feeding device 3 fixedly connected to its top, a drive motor 5 fixedly connected to its outer side, and a feeding device 6 fixedly connected to the output end of the drive motor 5. The outer side of the feeding device 6 is rotatably connected to the inner side of the feeding shell 2. The dust collection device 4 is used to absorb the dust generated by the feeding device 6 during the feeding process. The outer side of the dust collection device 4 is fixedly connected to the inner side of the base 1, and the top of the dust collection device 4 is fixedly connected to the top of the feeding shell 2. The base 1 serves as the supporting structure, and the feeding shell 2 fixedly connected to it forms the main frame. The feeding shell 2 works in coordination with the feeding device 3, the drive motor 5, the feeding device 6, and the dust collection device 4 to complete the functions of feeding, conveying, and purifying plastic granules.

[0040] The feeding device 3 includes a feeding hopper 31. A limiting shell 32 is fixedly connected to the outer side of the feeding hopper 31. A discharge pipe 33 is slidably connected to the inner wall of the feeding hopper 31. A support rod 34 is fixedly connected to the top of the discharge pipe 33. A conical sealing block 35 is fixedly connected to the top of the support rod 34. A drain cleaning frame 36 is fixedly connected to the top of the conical sealing block 35. A slider 37 is fixedly connected to the outer side of the discharge pipe 33. A guide rod 38 is fixedly connected to the top of the slider 37. A compression spring 39 is provided on the outer side of the guide rod 38. When the top block 624 pushes the slider 37 upward, the slider 37 drives the conical sealing block 35 upward through the support rod 34. At this time, the drain cleaning frame 36 also moves upward in a straight line. When the top block 624 disengages from the slider 37, the drain cleaning frame 36 moves downward under the elastic force of the compression spring 39. This cycle repeats, and the drain cleaning frame 36 performs periodic up-and-down movements within the feeding hopper 31. During its movement, the dredging frame 36 agitates and pushes the particles, allowing them to fall more orderly toward the feed pipe 33.

[0041] The feeding device 6 includes a rotating shell 61. A scraper assembly 62 is fixedly connected to the outer side of the rotating shell 61. A telescopic cylinder 64 is fixedly connected to the inner side of the rotating shell 61. A sliding rod 65 is fixedly connected to the output end of the telescopic cylinder 64. A fixing ring 66 is fixedly connected to the outer side of the sliding rod 65. A limit plate 68 is slidably connected to the outer side of the fixing ring 66. A rotating rod 67 is fixedly connected to the outer side of the limit plate 68. A fixing sleeve 69 is rotatably connected to the outer wall of the rotating rod 67. A feeding plate 63 is fixedly connected to the outer side of the rotating shell 61. The outer side of the rotating shell 61 is fixedly connected to the output end of the drive motor 5. The outer side of the scraper assembly 62 is fixedly connected to the inner wall of the feeding shell 2. The outer side of the fixing sleeve 69 is fixedly connected to the inner wall of the rotating shell 61. The feeding plates 63 are arranged in a ring along the central axis of the rotating shell 61. After the drive motor 5 starts, it drives the rotating shell 61 to rotate inside the feeding shell 2, providing rotational power for the entire feeding process. The feeding plates 63 are arranged in a ring along the central axis of the rotating shell 61. When the rotating shell 61 rotates, the feeding plates 63 rotate accordingly. Relying on centrifugal force and friction, the plastic granules located in the feeding shell 2 move along the axial direction of the feeding shell 2, realizing the granule conveying function. The telescopic cylinder 64 can extend and retract as needed. Through the sliding rod 65, it drives the fixed ring 66 to move, thereby causing the limiting plate 68 to slide along the fixed ring 66, thus changing the angle of the rotating rod 67 relative to the fixed sleeve 69, and finally realizing the adjustment of the tilt angle of the feeding plates 63. By adjusting the tilt angle of the feeding plates 63, the conveying speed, pushing force, and conveying volume of the plastic granules in the feeding shell 2 can be changed to adapt to different production process requirements and material conveying conditions.

[0042] The scraping assembly 62 includes a rotating ring 621, a baffle plate 622 rotatably connected to the outer side of the rotating ring 621, an arc-shaped scraper 623 fixedly connected to the outer side of the rotating ring 621, a top block 624 fixedly connected to the side of the rotating ring 621 away from the arc-shaped scraper 623, an inner side of the rotating ring 621 fixedly connected to the outer side of the rotating shell 61, an outer side of the baffle plate 622 fixedly connected to the inner wall of the feeding shell 2, an outer side of the arc-shaped scraper 623 slidably connected to the inner wall of the feeding shell 2, and an outer side of the top block 624 in contact with the bottom of the slider 37. The feed hopper 31... The bottom of the feeder 621 is fixedly connected to the top of the feeding shell 2. The side wall of the conical sealing block 35 contacts the inner wall of the feed hopper 31. The outer side of the slider 37 is slidably connected to the inner wall of the limiting shell 32. The top of the limiting shell 32 is slidably connected to the outer wall of the guide rod 38. The top of the compression spring 39 is fixedly connected to the top of the limiting shell 32. The bottom of the compression spring 39 is fixedly connected to the top of the slider 37. The bottom of the limiting shell 32 is fixedly connected to the top of the feeding shell 2. The main function of the baffle plate 622 in the scraping assembly 62 is to provide structural support for the feeding device 6. It provides a stable axial limit for the rotating ring 621, ensuring the stability of the entire rotating shell 61 and its connected components during operation. At the same time, the baffle plate 622 has a certain amount of space reserved in its structural design to allow material to pass through its bottom. During the feeding process, after the plastic granules fall from the feeding device 3 into the feeding shell 2, they can continue to move towards the discharge direction along the space between the bottom of the baffle plate 622 and the inner wall of the feeding shell 2. The presence of the baffle plate 622 will not obstruct the normal material conveying process, ensuring the smooth flow of the material conveying path. After the plastic granules fall from the discharge pipe 33 into the feeding shell 2, the rotation of the rotating ring 621 drives the arc-shaped scraper 623 to perform a circular motion. This pushes the material along the inner wall of the feeding shell 2 towards the discharge direction. This effectively prevents the material from accumulating in the feeding shell 2, especially in the critical area below the discharge pipe 33 where it is prone to buildup. By continuously guiding and pushing the material, the good flowability of the material in the feeding shell 2 is maintained, ensuring that the feeding device 6 can continuously and efficiently convey the plastic granules to the next production stage. When the drive motor 5 starts and drives the rotating shell 61 to rotate, the rotating ring 621, which is fixedly connected to the rotating shell 61, also rotates synchronously. During the rotation of the rotating ring 621, the top block 624 will perform circular motion along with the rotating ring 621. Whenever the top block 624 moves to the position of contact with the slider 37, the continuous circular motion of the top block 624 will generate an upward pushing force on the slider 37. As the connecting part of the feed tube 33, the slider 37 will slide upward within the limiting shell 32 after being subjected to the upward pushing force of the top block 624, thereby driving the feed tube 33 to move upward as a whole.At this time, the compression spring 39 on the outside of the guide rod 38 is compressed, and the support rod 34 drives the conical sealing block 35 to move upward, so that the material added to the feed hopper 31 can flow smoothly into the discharge pipe 33. The top block 624 periodically applies an upward pushing force to the slider 37, so that the particles in the discharge pipe 33 can fall into the feeding shell 2 at a certain rhythm and flow rate, avoiding a large amount of particles rushing in at once and causing blockage, or the slow discharge affecting the conveying efficiency. This achieves precise control of the feeding process of the feeding device 3, ensuring the stability and uniformity of the feeding of the entire conveying system. When the motor speed increases, the top block 624 rotates faster, which increases the feed flow rate, which matches the change in the conveying capacity of the feeding device 6. When the rotation speed of the rotating shell 61 increases, the feeding plate 63 in the feeding device 6 has an enhanced pushing ability for materials, and can convey materials along the feeding shell 2 to the discharge direction more quickly. The increased feed flow rate brought about by the accelerated rotation of the top block 624 is just enough to provide sufficient material for the feeding device 6, ensuring that the feeding device 6 will not run out of material and maintain a dynamic balance between the feeding and conveying processes.

[0043] The dust collection device 4 includes an air inlet duct 41, a rotating shaft 42 is rotatably connected to the inner side of the air inlet duct 41, a fan blade 44 is fixedly connected to the outer wall of the rotating shaft 42, a ventilation frame 43 is fixedly connected to the top of the air inlet duct 41, an air duct 45 is fixedly connected to the outer side of the air inlet duct 41, a filter assembly 46 is fixedly connected to the top of the air duct 45, a suction shell 47 is fixedly connected to the bottom of the filter assembly 46, the outer side of the air inlet duct 41 is fixedly connected to the inner side of the base 1, the outer side of the rotating shaft 42 is rotatably connected to the output end of the drive motor 5 through a pulley set, the bottom of the suction shell 47 is fixedly connected to the top of the feeding shell 2, and the top of the air inlet duct 41 is fixedly connected to the bottom of the feeding shell 2. When the drive motor 5 starts and drives the feeding device 6 to work, it also drives the rotating shaft 42 to rotate through the pulley set, thereby causing the fan blade 44 fixed to the outer wall of the rotating shaft 42 to rotate. The rotation of the fan blade 44 agitates the air inside the air inlet duct 41, creating a negative pressure area within it. At this time, the feeding shell 2 is filled with dust-laden air generated during the conveying of plastic granules. Under the pressure difference, the air is drawn in through the suction shell 47, which covers a certain area above the feeding shell 2 and effectively collects the dust-laden air raised during feeding and conveying operations. The dust-laden air drawn in by the suction shell 47 then enters the connected filter assembly 46, where most of the dust is trapped. The air after preliminary filtration continues to flow along the ventilation pipe 45, which serves as a connecting channel to deliver this air, which has had its dust content reduced, into the air inlet duct 41. The airflow entering the air inlet duct 41 is blown upwards into the feeding shell 2 through the ventilation frame 43. Since the airflow direction is from bottom to top, an upward airflow disturbance is formed inside the feeding shell 2. Dust generated during the conveying of plastic granules and settling at the bottom of the feeding shell 2 or adhering to the wall surface is easily blown up and suspended in the air by the upward airflow. At this time, the suction shell 47 maintains a negative pressure suction force, and the dust suspended in the air is sucked back into the suction shell 47 and then enters the filter assembly 46 for a new round of filtration and collection. This cycle repeats. Inside the feeding shell 2, the upward airflow created by the ventilation frame 43 continuously blows up newly generated dust and previously incompletely collected dust and sucks it into the dust collection system. Then, the filter assembly 46 effectively intercepts and collects the dust, so that the dust inside the feeding shell 2 can be collected as thoroughly as possible, achieving the purpose of purifying the air inside the feeding shell 2, reducing dust pollution, and preventing dust from mixing into the plastic granules and affecting product quality.

[0044] The filter assembly 46 includes a fixed cylinder 461, a knob 462 threadedly connected to the outer side of the fixed cylinder 461, a push rod 463 rotatably connected to the outer side of the knob 462, a filter cylinder 464 slidably connected to the inner side of the fixed cylinder 461, a return spring 465 fixedly connected to the inner side of the fixed cylinder 461, a sliding ring 466 fixedly connected to the outer side of the return spring 465, the bottom of the fixed cylinder 461 fixedly connected to the top of the suction shell 47, the outer side of the push rod 463 contacting the outer side of the filter cylinder 464, and the side of the filter cylinder 464 away from the push rod 463 contacting the sliding ring 464. The outer side of the ring 466 is in contact with the inner wall of the fixed cylinder 461. The outer side of the fixed cylinder 461 is fixedly connected to the top of the vent pipe 45. When the filter cylinder 464 needs to be disassembled for cleaning, replacement or maintenance, the operator manually rotates the knob 462. The knob 462 will move in a spiral motion along the outer wall of the fixed cylinder 461. At this time, the push rod 463 will move away from the filter cylinder 464 in the radial direction of the fixed cylinder 461. This process makes the push rod 463 gradually release the squeezing effect on the filter cylinder 464. During this process, the elastic potential energy stored in the return spring 465, which was originally in a compressed state, begins to be released. Under the action of the elastic force, the return spring 465 pushes the sliding ring 466 connected to it to slide outward along the inner wall of the fixed cylinder 461. The sliding of the sliding ring 466 will apply an outward pushing force to the filter cylinder 464, so that the filter cylinder 464 gradually moves from the internal space of the fixed cylinder 461 to the outside, thereby allowing the filter cylinder 464 to be removed from the fixed cylinder 461.

[0045] Working principle:

[0046] In use, the base 1 serves as the supporting structure, and the feeding shell 2 fixedly connected to it forms the main frame. The feeding shell 2 works in coordination with the feeding device 3, the drive motor 5, the feeding device 6, and the dust collection device 4 to complete the functions of feeding, conveying, and absorbing and purifying plastic granules.

[0047] After the drive motor 5 starts, it drives the rotating shell 61 to rotate inside the feeding shell 2, providing rotational power for the entire feeding process. The feeding plate 63 is arranged in a ring along the central axis of the rotating shell 61. When the rotating shell 61 rotates, the feeding plate 63 rotates accordingly. It relies on centrifugal force and friction to drive the plastic particles located in the feeding shell 2 to move along the axial direction of the feeding shell 2, thereby realizing the particle conveying function.

[0048] The telescopic cylinder 64 can extend and retract as needed, moving the fixed ring 66 via the sliding rod 65. This causes the limiting plate 68 to slide along the fixed ring 66, thereby changing the angle of the rotating rod 67 relative to the fixed sleeve 69, ultimately adjusting the tilt angle of the feeding plate 63. By adjusting the tilt angle of the feeding plate 63, parameters such as the conveying speed, pushing force, and conveying volume of plastic granules within the feeding shell 2 can be changed to adapt to different production process requirements and material conveying conditions.

[0049] The main function of the baffle plate 622 in the scraper assembly 62 is to provide structural support for the feeding device 6. It provides stable axial positioning for the rotating ring 621, ensuring the stability of the entire rotating shell 61 and its connected components during operation. Simultaneously, the baffle plate 622 has a reserved space in its structural design, allowing material to pass through its bottom. During the feeding process, after the plastic granules fall from the feeding device 3 into the feeding shell 2, they can continue to move in the discharge direction along the space between the bottom of the baffle plate 622 and the inner wall of the feeding shell 2, without obstructing the normal material conveying process due to the presence of the baffle plate 622, thus ensuring a smooth material conveying path.

[0050] After the plastic granules fall from the feed pipe 33 into the feeding shell 2, the rotation of the rotating ring 621 drives the arc-shaped scraper 623 to perform a circular motion. This pushes the material along the inner wall of the feeding shell 2 towards the discharge direction. This effectively prevents the material from accumulating inside the feeding shell 2, especially in the critical area below the feed pipe 33 where it is prone to buildup. By continuously guiding and pushing the material, good flowability of the material inside the feeding shell 2 is maintained, ensuring that the feeding device 6 can continuously and efficiently transport the plastic granules to the next production stage.

[0051] When the drive motor 5 starts and drives the rotating housing 61 to rotate, the rotating ring 621, which is fixedly connected to the rotating housing 61, also rotates synchronously. During the rotation of the rotating ring 621, the top block 624 will make a circular motion with the rotating ring 621. Whenever the top block 624 moves to the position of contacting the slider 37, the continuous circular motion of the top block 624 will generate an upward pushing force on the slider 37. As the connecting part of the feed tube 33, the slider 37 will slide upward in the limiting housing 32 after being pushed upward by the top block 624, and at the same time drive the feed tube 33 to move upward as a whole. At this time, the compression spring 39 on the outside of the guide rod 38 is compressed, and the support rod 34 drives the conical sealing block 35 to move upward, so that the material added into the feed hopper 31 can flow smoothly into the feed tube 33.

[0052] By periodically applying an upward pushing force to the slider 37 by the top block 624, the particles in the feed pipe 33 can fall into the feed shell 2 at a certain rhythm and flow rate, avoiding a large influx of particles at once that could cause blockage, or slow feeding that could affect the conveying efficiency. This achieves precise control over the feeding process of the feeding device 3, ensuring the stability and uniformity of the feeding of the entire conveying system.

[0053] As the motor speed increases, the top block 624 rotates faster, leading to an increase in the feed flow rate, which matches the change in the conveying capacity of the feeding device 6. With the increased speed of the rotating shell 61, the feeding plate 63 in the feeding device 6 has enhanced material pushing ability, enabling it to convey material more quickly along the feeding shell 2 towards the discharge direction. The increased feed flow rate resulting from the faster rotation of the top block 624 provides sufficient material to the feeding device 6, ensuring that it does not run dry and maintains a dynamic balance between the feeding and conveying processes.

[0054] Because the top block 624 on the rotating ring 621 makes circular motion and periodically contacts the slider 37, when the top block 624 pushes the slider 37 upward, the slider 37 drives the conical sealing block 35 upward through the support rod 34. At this time, the unblocking frame 36 also moves upward in a straight line. When the top block 624 disengages from the slider 37, the unblocking frame 36 moves downward under the elastic force of the compression spring 39. This cycle repeats, and the unblocking frame 36 makes periodic up-and-down movements within the feed hopper 31. During the movement, the unblocking frame 36 agitates and pushes the particles, allowing them to fall more orderly towards the discharge pipe 33.

[0055] When the drive motor 5 starts and drives the feeding device 6 to work, it also drives the rotating shaft 42 to rotate through the pulley set, which in turn causes the fan blades 44 fixed on the outer wall of the rotating shaft 42 to rotate. The rotation of the fan blades 44 agitates the air inside the air inlet duct 41, thereby creating a negative pressure area inside the air inlet duct 41. At this time, the feeding shell 2 is filled with dust-laden air generated during the conveying of plastic granules. Under the action of the pressure difference, the air is sucked in through the suction shell 47. The suction shell 47 covers a certain area above the feeding shell 2 and can effectively collect the dust-laden air raised during feeding and other operations.

[0056] The dust-laden air drawn in by the suction housing 47 then enters the filter assembly 46 connected to it, so that most of the dust is trapped in the filter assembly 46. The air after preliminary filtration continues to flow along the ventilation pipe 45, which serves as a connecting channel to deliver this part of the air with reduced dust content to the air inlet duct 41.

[0057] The airflow entering the air inlet duct 41 is blown upwards into the feeding shell 2 via the ventilation frame 43. Because the airflow direction is upwards, an upward airflow disturbance is formed inside the feeding shell 2. Dust generated during the plastic granule conveying process and settling at the bottom of the feeding shell 2 or adhering to the wall surface is easily blown up again and suspended in the air by this upward airflow. At this time, the suction shell 47 maintains a negative pressure suction force, and the dust suspended in the air is sucked back into the suction shell 47, then enters the filter assembly 46 for a new round of filtration and collection. This cycle repeats continuously. Inside the feeding shell 2, the upward airflow created by the ventilation frame 43 continuously blows up newly generated dust and previously incompletely collected dust and sucks it into the dust collection system. Then, the filter assembly 46 effectively intercepts and collects the dust, ensuring that the dust inside the feeding shell 2 is collected as thoroughly as possible. This achieves the purpose of purifying the air inside the feeding shell 2, reducing dust pollution, and preventing dust from mixing with plastic granules and affecting product quality.

[0058] When the filter cartridge 464 needs to be disassembled for cleaning, replacement, or maintenance, the operator manually rotates the knob 462. The knob 462 will move spirally along the outer wall of the fixed cylinder 461. At this time, the push rod 463 will move radially away from the filter cartridge 464 along the fixed cylinder 461. This process gradually releases the squeezing effect of the push rod 463 on the filter cartridge 464. During this process, the elastic potential energy stored in the return spring 465, which was originally in a compressed state, begins to be released. Under the action of the elastic force, the return spring 465 will push the sliding ring 466 connected to it to slide outward along the inner wall of the fixed cylinder 461. The sliding of the sliding ring 466 will apply an outward pushing force to the filter cartridge 464, causing the filter cartridge 464 to gradually move outward from the internal space of the fixed cylinder 461, thereby allowing the filter cartridge 464 to be removed from the fixed cylinder 461.
