Description

Technical Field

[0001] The present invention relates to the technical field of conveying, and particularly relates to a conveying system for plastic particle processing and production. Background Art

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

[0003] In the prior art, during the feeding process of plastic particles, problems such as uneven feeding and blockage are likely to occur. Common feeding devices rely solely on simple gravity feeding methods and lack effective mechanisms to ensure that materials can enter the conveying pipeline or conveying housing at a stable and appropriate flow rate. Once situations such as material caking and bridging occur, it will cause the feeding to be interrupted, affecting subsequent conveying work. That is, either the conveying device runs idly due to insufficient feeding, wasting energy and affecting the production progress, or the entire conveying system is paralyzed due to excessive feeding, bringing great troubles to production. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a conveying system for plastic particle processing and production, including: a base, a feeding housing is fixedly connected to the top of the base, a feeding device is fixedly connected to the top of the feeding housing, a driving motor is fixedly connected to the outside of the feeding housing, an output end of the driving motor is fixedly connected to a feeding device, and the outside of the feeding device is rotationally connected to the inside of the feeding housing; a dust suction device, the dust suction device is used to absorb dust generated during the feeding process of the feeding device, the outside of the dust suction device is fixedly connected to the inside of the base, and the top of the dust suction device is fixedly connected to the top of the feeding housing. The base serves as a support structure, and the feeding housing fixedly connected thereto forms the main framework. The feeding housing cooperates with the feeding device, the driving motor, the feeding device, and the dust suction device to work together to complete functions such as feeding, conveying, and dust absorption and purification of plastic particles; The feeding device includes a feeding hopper. A limiting shell is fixedly connected to the outside of the feeding hopper. A blanking pipe is slidably connected to the inner wall of the feeding hopper. A support rod is fixedly connected to the top of the blanking pipe. A conical sealing block is fixedly connected to the top of the support rod. A dredging frame is fixedly connected to the top of the conical sealing block. A slider is fixedly connected to the outside of the blanking pipe. A guide rod is fixedly connected to the top of the slider. A compression spring is arranged on the outside of the guide rod. After the slider is subjected to the upward pushing force of the top block, it will slide upward in the limiting shell, and at the same time drive the whole blanking pipe to move upward. At this time, the compression spring on the outside of the guide rod is compressed by force. At this time, the support rod drives the conical sealing block to move upward, so that the materials added to the feeding hopper can smoothly flow into the blanking pipe; The feeding device includes a rotating shell. A scraping component is fixedly connected to the outside of the rotating shell. A telescopic cylinder is fixedly connected to the inside of the rotating shell. A sliding rod is fixedly connected to the output end of the telescopic cylinder. A fixing ring is fixedly connected to the outside of the sliding rod. A limiting plate is slidably connected to the outside of the fixing ring. A rotating rod is fixedly connected to the outside of the limiting plate. A fixing sleeve is rotatably connected to the outer wall of the rotating rod. A feeding plate is fixedly connected to the outside of the rotating rod. The telescopic cylinder can perform telescopic actions as needed. It drives the fixing ring to move through the sliding rod, and then makes the limiting plate slide along the fixing ring, so as to change the angle of the rotating rod relative to the fixing sleeve, and finally realize the adjustment of the inclination angle of the feeding plate.

[0005] Preferably, the outside of the rotating shell is fixedly connected to the output end of a driving motor. The outside of the scraping component is fixedly connected to the inner wall of the feeding shell. The outside of the fixing sleeve is fixedly connected to the inner wall of the rotating shell. The feeding plates are arranged annularly along the central axis of the rotating shell. When the rotating shell rotates, the feeding plates rotate accordingly, and rely on centrifugal force and friction to drive the plastic particles in the feeding shell to move along the axial direction of the feeding shell.

[0006] Preferably, the scraping component includes a rotating ring. A baffle plate is rotatably connected to the outside of the rotating ring. The main function of the baffle plate is to provide structural support for the feeding device. It provides stable axial limit for the rotating ring, and ensures the stability of the whole rotating shell and its connected components during operation. An arc-shaped scraping rod is fixedly connected to the outside of the rotating ring. A top block is fixedly connected to the side of the rotating ring away from the arc-shaped scraping rod. The rotation of the rotating ring drives the arc-shaped scraping rod to make a circular motion together. It pushes the materials along the inner wall of the feeding shell towards the discharging direction. Effectively prevents materials from accumulating in the feeding shell.

[0007] Preferably, the inner side of the rotating ring is fixedly connected to the outer side of the rotating shell, the outer side of the material baffle is fixedly connected to the inner wall of the feeding shell, the outer side of the arc-shaped scraping rod is slidably connected to the inner wall of the feeding shell, and the outer side of the top block contacts the bottom of the slider. By periodically applying an upward pushing force on the slider by the top block, the particles in the blanking pipe can uniformly fall into the feeding shell at a certain rhythm and flow rate.

[0008] 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 contacts 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 guiding rod. When the top block pushes the slider to move upward, the slider drives the conical sealing block to move upward through the support rod, and at this time, the dredging frame also moves upward in a straight line accordingly.

[0009] Preferably, the top end of the compression spring is fixedly connected to the top of the limiting shell, the bottom end of the compression spring is fixedly connected to the top of the slider, and the bottom of the limiting shell is fixedly connected to the top of the feeding shell. During the movement of the dredging frame, its stirring and pushing effects on the particles can make the particles fall more orderly towards the direction of the blanking pipe.

[0010] Preferably, the dust suction device includes an air inlet cylinder, a rotating shaft is rotatably connected to the inner side of the air inlet cylinder, a fan blade is fixedly connected to the outer wall of the rotating shaft, a ventilation frame is fixedly connected to the top of the air inlet cylinder, an air pipe is fixedly connected to the outer side of the air inlet cylinder, a filtering component is fixedly connected to the top end of the air pipe, and a suction shell is fixedly connected to the bottom of the filtering component. The rotation of the fan blade stirs the air inside the air inlet cylinder, thereby forming a negative pressure area inside the air inlet cylinder. At this time, the feeding shell is filled with dust-containing air generated during the conveying of plastic particles, and under the action of the pressure difference, it will be sucked in through the suction shell. The suction shell covers a certain area above the feeding shell and can effectively collect the dust-containing air raised during operations such as feeding and conveying; the dust-containing air sucked into the suction shell then enters the connected filtering component, so that most of the dust is intercepted inside the filtering component, and the air after preliminary filtration continues to flow along the air pipe. The air pipe serves as a connecting channel to convey this part of the air with a reduced dust content into the air inlet cylinder.

[0011] Preferably, the outer side of the air inlet cylinder is fixedly connected to the inner side of the base, the outer side of the rotating shaft is rotationally connected to the output end of the driving motor through a pulley group, the bottom of the suction shell is fixedly connected to the top of the feeding shell, and the top of the air inlet cylinder is fixedly connected to the bottom of the feeding shell. The air flow entering the air inlet cylinder will blow upward from the bottom to the inside of the feeding shell through the ventilation frame. Since the air flow direction is from bottom to top, an upward air flow disturbance is formed inside the feeding shell. During the transportation of plastic particles, the dust generated and settled at the bottom of the feeding shell or attached to the wall surface is easily blown up again and suspended in the air under the action of this upward air flow.

[0012] Preferably, the filter assembly includes a fixed cylinder, a knob is threadedly connected to the outer side of the fixed cylinder, a push rod is rotationally connected to the outer side of the knob, a filter cylinder is slidably connected to the inner side of the fixed cylinder, a return spring is fixedly connected to the inner side of the fixed cylinder, and a sliding ring is fixedly connected to the outer side of the return spring. When the operator manually rotates the knob, the knob will perform a spiral movement 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, and this process gradually releases the extrusion effect of the push rod on the filter cylinder.

[0013] 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 end of the ventilation pipe. When the elastic potential energy stored in the originally compressed return spring begins to be released, under the action of the elastic force, the return spring will push the connected sliding ring to slide outward along the inner wall of the fixed cylinder, and the sliding of the sliding ring will apply an outward thrust to the filter cylinder, causing the filter cylinder to gradually move from the inner space of the fixed cylinder to the outside.

[0014] The beneficial effects of the present invention are as follows: 1. By setting the feeding device, the telescopic cylinder can perform telescopic actions as needed. It drives the fixed ring to move through the sliding rod, and then makes the limiting plate slide along the fixed ring, thereby changing the angle of the rotating rod relative to the fixed sleeve, and finally realizing the adjustment of the inclination angle of the feeding plate. By adjusting the inclination angle of the feeding plate, parameters such as the conveying speed, pushing force, and conveying volume of plastic particles in the feeding shell can be changed to adapt to different production process requirements and material conveying conditions.

[0015] 2. The present invention provides a baffle plate. The main function of the baffle plate is to provide structural support for the feeding device, providing stable axial limit for the rotating ring, and ensuring the stability of the entire rotating shell and the components connected thereto during operation. At the same time, a certain space is reserved in the structural design of the baffle plate to allow the material to pass through its bottom. During the feeding process, after the plastic particles fall into the feeding shell from the feeding device, they can continue to move towards the discharging direction along the space between the bottom of the baffle plate and the inner wall of the feeding shell, without being blocked by the baffle plate and ensuring the smoothness of the material conveying path.

[0016] 3. The present invention provides an arc-shaped scraping rod. After the plastic particles fall from the feeding pipe into the feeding shell, the rotation of the rotating ring drives the arc-shaped scraping rod to perform a circular motion together, pushing the material along the inner wall of the feeding shell towards the discharging direction, effectively preventing the material from accumulating in the feeding shell, especially in the key area under the feeding pipe where it is prone to accumulation. By continuously guiding and pushing the material, the good fluidity of the material in the feeding shell is maintained, ensuring that the feeding device can continuously and efficiently convey the plastic particles to the next production link.

[0017] 4. The present invention provides a rotating ring. During the rotation of the rotating ring, the top block will perform a circular motion along with the rotating ring. Whenever the top block moves to the position where it contacts the slider, due to the continuous circular motion of the top block, an upward pushing force will be generated on the slider. As the connecting component of the feeding pipe, after being subjected to the upward pushing force of the top block, the slider will slide upward in the limiting shell, simultaneously driving the entire feeding pipe to move upward. At this time, the compression spring outside the guiding rod is compressed, and the supporting rod drives the conical sealing block to move upward, enabling the material added to the feeding hopper to smoothly flow into the feeding pipe.

[0018] 5. The present invention periodically applies an upward pushing force to the slider through the top block. When the motor speed increases, the up-and-down movement of the top block becomes faster, promoting an increase in the feeding flow rate, which is matched with the change in the conveying capacity of the feeding device. When the rotating speed of the rotating shell in the feeding device increases, the pushing ability of the feeding plate for the material is enhanced, and the material can be conveyed along the feeding shell towards the discharging direction faster. The increase in the feeding flow rate brought about by the faster up-and-down movement of the top block just provides enough material for the feeding device, ensuring that the feeding device does not experience an idling situation of "no material to convey", and maintaining the dynamic balance between the feeding and conveying links.

[0019] 6. By providing a dredging frame in the present invention, since the top blocks on the rotating ring perform circular motion and periodically contact the sliders, when a top block pushes a slider upward, the slider drives the conical sealing block to move upward through the support rod, and at this time, the dredging frame also moves upward in a straight line accordingly; when the top block disengages from the slider, under the elastic force of the compression spring, the dredging frame moves downward correspondingly. In this way, the dredging frame performs periodic up-and-down motion in the feed hopper. During the movement of the dredging frame, its stirring and pushing effects on the particles can make the particles fall more orderly towards the direction of the discharge pipe.

[0020] 7. By providing a dust suction device in the present invention, when the drive motor starts to drive the feeding device to work, it also drives the rotation of the rotating shaft through the pulley group, and then makes the fan blades fixed on the outer wall of the rotating shaft rotate. The rotation of the fan blades stirs the air inside the air inlet cylinder, thereby forming a negative pressure area inside the air inlet cylinder. At this time, the feeding shell is filled with dust-containing air generated during the conveying process of plastic particles, and it will be sucked in through the suction shell under the action of the pressure difference. The suction shell covers a certain area above the feeding shell and can effectively collect the dust-containing air raised during operations such as feeding and conveying.

[0021] 8. By providing a dust suction device in the present invention, the air flow entering the air inlet cylinder will blow upward from the bottom to the inside of the feeding shell through the ventilation frame. Since the air flow direction is from bottom to top, an upward air flow disturbance is formed inside the feeding shell. During the conveying process of plastic particles, the dust that settles at the bottom of the feeding shell or adheres to the wall surface is easily blown up again and suspended in the air under the action of this upward air flow. At this time, the suction shell continuously maintains a negative pressure suction, and the dust suspended in the air will be sucked in by the suction shell again, and then enters the filtration assembly for a new round of filtration and collection. In this way, in the feeding shell, the upward air flow created by the ventilation frame continuously blows up and sucks the newly generated and previously incompletely collected dust into the dust suction system, and then relies on the filtration assembly to effectively intercept and collect the dust, so that the dust inside the feeding shell can be collected as thoroughly as possible, achieving the purpose of purifying the air inside the feeding shell, reducing dust pollution, and preventing dust from mixing into plastic particles and affecting product quality.

[0022] 9. By providing a filtration assembly in the present invention, when it is necessary to disassemble the filter cartridge for cleaning, replacement or maintenance, the operator manually rotates the knob, so that the ejector rod gradually releases the extrusion effect on the filter cartridge. During this process, the elastic potential energy stored in the reset spring that was originally in a compressed state begins to be released, causing the filter cartridge to gradually move from the internal space of the fixed cylinder to the outside, and thus the filter cartridge can be taken out of the fixed cylinder.

The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0026] Embodiment: Please refer to Figure 1 - Figure 10 , the present invention provides a technical solution: A conveying system for plastic particle processing and production, comprising: Base 1, a feeding shell 2 is fixedly connected to the top of the base 1, a feeding device 3 is fixedly connected to the top of the feeding shell 2, a driving motor 5 is fixedly connected to the outside of the feeding shell 2, an output end of the driving motor 5 is fixedly connected to a feeding device 6, and the outside of the feeding device 6 is rotationally connected to the inside of the feeding shell 2; a dust suction device 4, the dust suction device 4 is used for absorbing dust generated during the feeding process of the feeding device 6, the outside of the dust suction device 4 is fixedly connected to the inside of the base 1, and the top of the dust suction device 4 is fixedly connected to the top of the feeding shell 2. With the base 1 as the support structure, the feeding shell 2 fixedly connected thereto constitutes the main frame. The feeding shell 2 cooperates with the feeding device 3, the driving motor 5, the feeding device 6 and the dust suction device 4 to complete functions such as feeding, conveying and dust absorption and purification of plastic particles; The feeding device 3 includes a feeding hopper 31, a limiting shell 32 is fixedly connected to the outside of the feeding hopper 31, a blanking 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 blanking pipe 33, a conical sealing block 35 is fixedly connected to the top of the support rod 34, a dredging frame 36 is fixedly connected to the top of the conical sealing block 35, a slider 37 is fixedly connected to the outside of the blanking pipe 33, a guide rod 38 is fixedly connected to the top of the slider 37, and a compression spring 39 is arranged on the outside of the guide rod 38. When the top block 624 pushes the slider 37 to move upward, the slider 37 drives the conical sealing block 35 to move upward through the support rod 34. At this time, the dredging frame 36 also moves upward in a straight line; when the top block 624 is separated from the slider 37, the dredging frame 36 moves downward correspondingly under the elastic force of the compression spring 39. In this way, the dredging frame 36 makes periodic up and down movements in the feeding hopper 31. During the movement of the dredging frame 36, its stirring and pushing effects on the particles can make the particles fall more orderly in the direction of the blanking pipe 33; The feeding device 6 includes a rotating shell 61. A scraping component 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. The output end of the telescopic cylinder 64 is fixedly connected to a sliding rod 65. A fixing ring 66 is fixedly connected to the outer side of the sliding rod 65. A limiting 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 limiting plate 68. The outer wall of the rotating rod 67 is rotatably connected to a fixing sleeve 69. A feeding plate 63 is fixedly connected to the outer side of the rotating rod 67. The outer side of the rotating shell 61 is fixedly connected to the output end of the driving motor 5. The outer side of the scraping component 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 annularly along the central axis of the rotating shell 61. After the driving motor 5 is started, 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 annularly along the central axis of the rotating shell 61. When the rotating shell 61 rotates, the feeding plates 63 rotate accordingly, driving the plastic particles located inside the feeding shell 2 to move axially along the feeding shell 2 by relying on centrifugal force and friction force, realizing the conveying function of the particles. The telescopic cylinder 64 can perform telescopic actions as needed, driving the fixing ring 66 to move through the sliding rod 65, and then enabling the limiting plate 68 to slide along the fixing ring 66, thereby changing the angle of the rotating rod 67 relative to the fixing sleeve 69, and finally realizing the adjustment of the inclination angle of the feeding plate 63. By adjusting the inclination angle of the feeding plate 63, parameters such as the conveying speed, pushing force, and conveying volume of the plastic particles inside the feeding shell 2 can be changed to adapt to different production process requirements and material conveying situations.

[0027] The scraping component 62 includes a rotating ring 621. A baffle 622 is rotatably connected to the outer side of the rotating ring 621. An arc-shaped scraping rod 623 is fixedly connected to the outer side of the rotating ring 621. A top block 624 is fixedly connected to the side of the rotating ring 621 away from the arc-shaped scraping rod 623. The inner side of the rotating ring 621 is fixedly connected to the outer side of the rotating shell 61. The outer side of the baffle 622 is fixedly connected to the inner wall of the feeding shell 2. The outer side of the arc-shaped scraping rod 623 is slidably connected to the inner wall of the feeding shell 2. The outer side of the top block 624 is in contact with the bottom of the slider 37. The bottom of the feed hopper 31 is fixedly connected to the top of the feeding shell 2. The side wall of the conical sealing block 35 is in contact with 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 guiding rod 38. The top end of the compression spring 39 is fixedly connected to the top of the limiting shell 32. The bottom end 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 622 in the scraping component 62 is to provide structural support for the feeding device 6. It provides stable axial limitation for the rotating ring 621, ensuring the stability of the entire rotating shell 61 and the components connected thereto during operation. At the same time, a certain space is reserved in the structural design of the baffle 622 to allow materials to pass through its bottom. During the feeding process, after the plastic particles fall from the feeding device 3 into the feeding shell 2, they can continue to move towards the discharging direction along the space between the bottom of the baffle 622 and the inner wall of the feeding shell 2, without being blocked by the baffle 622 and hindering the normal feeding process, ensuring the smoothness of the material feeding path. After the plastic particles fall from the feeding pipe 33 into the feeding shell 2, the rotation of the rotating ring 621 drives the arc-shaped scraping rod 623 to do circular motion together. The materials are pushed along the inner wall of the feeding shell 2 towards the discharging direction. It effectively prevents the materials from accumulating in the feeding shell 2, especially in the key area under the feeding pipe 33 where accumulation is likely to occur. By continuously guiding and pushing the materials, the good fluidity of the materials in the feeding shell 2 is maintained, ensuring that the feeding device 6 can continuously and efficiently transport the plastic particles to the next production link. When the driving motor 5 starts to drive the rotating shell 61 to rotate, the rotating ring 621 fixedly connected to the rotating shell 61 also rotates synchronously. During the rotation of the rotating ring 621, the top block 624 will do circular motion along with the rotating ring 621. Whenever the top block 624 moves to the position in contact with the slider 37, due to the continuous circular motion of the top block 624, an upward pushing force will be generated on the slider 37. The slider 37, as the connecting component of the feeding pipe 33, will slide upward in the limiting shell 32 under the action of the upward pushing force of the top block 624, and at the same time drive the entire feeding pipe 33 to move upward.At this time, the compression spring 39 outside the guide rod 38 is compressed under force. At this time, the support rod 34 drives the conical seal block 35 to move upward, so that the materials added into the feed hopper 31 can smoothly flow into the blanking pipe 33. By periodically applying an upward pushing force to the slider 37 through the top block 624, the particles in the blanking pipe 33 can fall into the feeding shell 2 evenly at a certain rhythm and flow rate, avoiding a large amount of particles surging in at one time causing blockage, or the blanking being too slow affecting the conveying efficiency, thus realizing the precise control of the blanking process of the feeding device 3 and ensuring the stability and uniformity of the feeding of the entire conveying system. When the motor speed increases, the rotation of the top block 624 becomes faster, prompting the feeding flow rate to increase, which is matched with the change in the conveying capacity of the feeding device 6. The feeding plate 63 in the feeding device 6 has an enhanced pushing ability for the materials when the rotation speed of the rotating shell 61 increases, and can convey the materials along the feeding shell 2 towards the discharging direction faster. The increase in the feeding flow rate brought about by the faster rotation of the top block 624 can just provide enough materials for the feeding device 6, ensuring that the feeding device 6 does not have an idling situation of "no materials to convey", and maintaining the dynamic balance between the feeding and feeding links.

[0028] The dust suction device 4 includes an air inlet cylinder 41. A rotating shaft 42 is rotatably connected to the inner side of the air inlet cylinder 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 cylinder 41. An air pipe 45 is fixedly connected to the outer side of the air inlet cylinder 41. The top of the air pipe 45 is fixedly connected to a filtering component 46. The bottom of the filtering component 46 is fixedly connected to an air suction shell 47. The outer side of the air inlet cylinder 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 a driving motor 5 through a pulley group. The bottom of the air suction shell 47 is fixedly connected to the top of the feeding shell 2. The top of the air inlet cylinder 41 is fixedly connected to the bottom of the feeding shell 2. When the driving motor 5 starts to drive the feeding device 6 to work, it also drives the rotating shaft 42 to rotate through the pulley group, and then the fan blade 44 fixed to the outer wall of the rotating shaft 42 rotates. The rotation of the fan blade 44 stirs the air inside the air inlet cylinder 41, thereby forming a negative pressure area inside the air inlet cylinder 41. At this time, the feeding shell 2 is filled with dust-containing air generated during the transportation of plastic particles, and it will be sucked in through the air suction shell 47 under the action of the pressure difference. The air suction shell 47 covers a certain area above the feeding shell 2 and can effectively collect the dust-containing air raised during operations such as feeding and material conveying. The dust-containing air sucked into the air suction shell 47 then enters the connected filtering component 46, so that most of the dust is intercepted inside the filtering component 46, and the air after preliminary filtration continues to flow along the air pipe 45. The air pipe 45 serves as a connection channel to convey this part of the air with a reduced dust content into the air inlet cylinder 41. The air flow entering the air inlet cylinder 41 will blow from the bottom up to the inside of the feeding shell 2 through the ventilation frame 43. Since the air flow direction is from bottom to top, an upward air flow disturbance is formed inside the feeding shell 2. The dust generated and settled at the bottom of the feeding shell 2 or attached to the wall surface during the transportation of plastic particles is easily blown up again and suspended in the air under the action of this upward air flow. At this time, the air suction shell 47 continuously maintains a negative pressure suction, and the dust suspended in the air will be sucked into the air suction shell 47 again, and then enter the filtering component 46 for a new round of filtration and collection. In this way, in the feeding shell 2, the upward air flow created by the ventilation frame 43 continuously blows up and sucks the newly generated and previously incompletely collected dust into the dust suction system, and then relies on the filtering component 46 for effective dust interception and collection, 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 plastic particles and affecting product quality.

[0029] The filter component 46 includes a fixed cylinder 461. A knob 462 is threadedly connected to the outer side of the fixed cylinder 461. A push rod 463 is rotatably connected to the outer side of the knob 462. A filter cylinder 464 is slidably connected to the inner side of the fixed cylinder 461. A return spring 465 is fixedly connected to the inner side of the fixed cylinder 461. A sliding ring 466 is fixedly connected to the outer side of the return spring 465. The bottom of the fixed cylinder 461 is fixedly connected to the top of the suction housing 47. The outer side of the push rod 463 is in contact with the outer side of the filter cylinder 464. One side of the filter cylinder 464 away from the push rod 463 is in contact with the outer side of the sliding ring 466. The outer side of the sliding ring 466 is slidably connected to the inner wall of the fixed cylinder 461. The outer side of the fixed cylinder 461 is fixedly connected to the top end of the ventilation pipe 45. When it is necessary to disassemble the filter cylinder 464 for cleaning, replacement or maintenance, the operator manually rotates the knob 462. The knob 462 will perform a spiral movement along the outer wall of the fixed cylinder 461. At this time, the push rod 463 will move in a radial direction away from the filter cylinder 464 along the fixed cylinder 461. This process causes the push rod 463 to gradually release the extrusion force on the filter cylinder 464. During this process, the elastic potential energy stored in the originally compressed return spring 465 begins to be released. Under the action of the elastic force, the return spring 465 will push the connected sliding ring 466 to slide outward along the inner wall of the fixed cylinder 461. The sliding of the sliding ring 466 will exert an outward thrust on the filter cylinder 464, causing the filter cylinder 464 to gradually move from the internal space of the fixed cylinder 461 to the outside, and thus the filter cylinder 464 can be taken out of the fixed cylinder 461.

[0030] Working principle: During use, the base 1 serves as a support structure, and the feeding housing 2 fixedly connected thereto constitutes the main frame. The feeding housing 2 cooperates with the feeding device 3, the driving motor 5, the feeding device 6 and the dust suction device 4 to complete functions such as feeding, conveying and dust absorption and purification of plastic particles.

[0031] After the driving motor 5 is started, it drives the rotating housing 61 to rotate inside the feeding housing 2, providing rotational power for the entire feeding process. The feeding plates 63 are arranged annularly along the central axis of the rotating housing 61. When the rotating housing 61 rotates, the feeding plates 63 rotate accordingly, and rely on centrifugal force and friction to drive the plastic particles located in the feeding housing 2 to move along the axial direction of the feeding housing 2, realizing the conveying function of the particles.

[0032] The telescopic cylinder 64 can perform telescopic actions as needed. It drives the fixed ring 66 to move through the sliding rod 65, and then makes the limit plate 68 slide along the fixed ring 66, thereby changing the angle of the rotating rod 67 relative to the fixed sleeve 69, and finally realizing the adjustment of the inclination angle of the feeding plate 63. By adjusting the inclination angle of the feeding plate 63, parameters such as the conveying speed, pushing force, and conveying volume of the plastic particles in the feeding shell 2 can be changed to adapt to different production process requirements and material conveying conditions.

[0033] The main function of the baffle plate 622 in the scraping component 62 is to provide structural support for the feeding device 6. It provides 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, a certain space is reserved in the structural design of the baffle plate 622 to allow materials to pass through its bottom. During the feeding process, after the plastic particles fall from the feeding device 3 into the feeding shell 2, they can continue to move towards the discharging direction along the space between the bottom of the baffle plate 622 and the inner wall of the feeding shell 2, without being blocked by the baffle plate 622 and ensuring the smoothness of the material conveying path.

[0034] After the plastic particles fall from the feeding pipe 33 into the feeding shell 2, the rotation of the rotating ring 621 drives the arc-shaped scraping rod 623 to perform a circular motion together. It pushes the materials along the inner wall of the feeding shell 2 towards the discharging direction. Effectively prevents the materials from accumulating in the feeding shell 2, especially in the key area under the feeding pipe 33 where it is easy to accumulate. By continuously guiding and pushing the materials, it maintains the good fluidity of the materials in the feeding shell 2, ensuring that the feeding device 6 can continuously and efficiently convey the plastic particles to the next production link.

[0035] When the driving motor 5 starts to drive the rotating shell 61 to rotate, the rotating ring 621 fixedly connected to the rotating shell 61 also rotates synchronously. During the rotation of the rotating ring 621, the top block 624 will perform a circular motion along with the rotating ring 621. Whenever the top block 624 moves to the position where it contacts the slider 37, due to the continuous circular motion of the top block 624, an upward pushing force will be generated on the slider 37. The slider 37, as a connecting component of the feeding pipe 33, will slide upward in the limit shell 32 under the action of the upward pushing force of the top block 624, and at the same time drive the entire feeding pipe 33 to move upward. At this time, the compression spring 39 outside the guide rod 38 is compressed, and the support rod 34 drives the conical sealing block 35 to move upward, so that the materials added to the feeding hopper 31 can smoothly flow into the feeding pipe 33; By periodically applying an upward pushing force to the slider 37 through the top block 624, the particles in the blanking pipe 33 can fall evenly into the feeding shell 2 at a certain rhythm and flow rate, avoiding a large amount of particles pouring in at once, which may cause blockage, or the blanking being too slow, affecting the conveying efficiency. Thus, the accurate control of the blanking process of the feeding device 3 is realized, ensuring the stability and uniformity of the feeding of the entire conveying system.

[0036] When the motor speed increases, the rotation of the top block 624 speeds up, promoting an increase in the feeding flow rate, which matches the change in the conveying capacity of the feeding device 6. When the rotation speed of the rotating shell 61 of the feeding device 6 increases, the pushing ability of the feeding plate 63 in the feeding device 6 to the material is enhanced, and it can convey the material along the feeding shell 2 towards the discharging direction faster. The increase in the feeding flow rate brought about by the faster rotation of the top block 624 can just provide enough material for the feeding device 6, ensuring that the feeding device 6 does not have an idling situation of "no material to convey", maintaining the dynamic balance between the feeding and feeding links.

[0037] Since the top block 624 on the rotating ring 621 makes a 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 dredging frame 36 also moves upward in a straight line; when the top block 624 disengages from the slider 37, under the elastic force of the compression spring 39, the dredging frame 36 moves downward accordingly. In this way, the dredging frame 36 makes a periodic up and down movement in the feed hopper 31. During the movement of the dredging frame 36, its stirring and pushing effects on the particles can make the particles fall more orderly towards the blanking pipe 33.

[0038] When the driving motor 5 starts to drive the feeding device 6 to work, it also drives the rotation of the rotating shaft 42 through the pulley group, and then makes the fan blade 44 fixed on the outer wall of the rotating shaft 42 rotate. The rotation of the fan blade 44 stirs the air inside the air inlet cylinder 41, thus forming a negative pressure area inside the air inlet cylinder 41. At this time, the feeding shell 2 is filled with the dust-containing air generated during the conveying of plastic particles, and it will be sucked in through the suction shell 47 under the action of the pressure difference. The suction shell 47 covers a certain area above the feeding shell 2 and can effectively collect the dust-containing air raised during operations such as feeding and feeding; The dust-containing air sucked in by the suction shell 47 then enters the connected filtering component 46, so that most of the dust is intercepted inside the filtering component 46, and the air after preliminary filtering continues to flow along the air pipe 45. The air pipe 45, as a connecting channel, conveys this part of the air with a reduced dust content to the air inlet cylinder 41.

[0039] The air flow entering the air inlet duct 41 will blow upward from the bottom to the inside of the feeding housing 2 through the ventilation rack 43. Since the air flow direction is from bottom to top, an upward air flow disturbance is formed inside the feeding housing 2. During the transportation of plastic particles, the dust generated and settled at the bottom of the feeding housing 2 or attached to the wall surface is easily blown up again and suspended in the air under the action of this upward air flow. At this time, the suction housing 47 continuously maintains a negative pressure suction, and the dust suspended in the air will be sucked into the suction housing 47 again, and then enter the filter assembly 46 for a new round of filtration and collection. In this way, in the feeding housing 2, the upward air flow created by the ventilation rack 43 continuously blows up and sucks the newly generated and previously incompletely collected dust into the dust collection system, and then relies on the filter assembly 46 to effectively intercept and collect the dust, so that the dust inside the feeding housing 2 can be collected as thoroughly as possible, achieving the purpose of purifying the air inside the feeding housing 2, reducing dust pollution, and preventing dust from mixing into plastic particles and affecting product quality.

[0040] When it is necessary to disassemble the filter cartridge 464 for cleaning, replacement or maintenance, the operator manually rotates the knob 462, and the knob 462 will perform a spiral movement along the outer wall of the fixed cylinder 461. At this time, the ejector rod 463 will move away from the filter cartridge 464 along the radial direction of the fixed cylinder 461. This process causes the ejector rod 463 to gradually release the extrusion effect on the filter cartridge 464. During this process, the elastic potential energy stored in the reset spring 465, which was originally in a compressed state, begins to be released. Under the action of the elastic force, the reset 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 thrust to the filter cartridge 464, causing the filter cartridge 464 to gradually move from the inner space of the fixed cylinder 461 to the outside, and thus the filter cartridge 464 can be taken out of the fixed cylinder 461.
