Description

Technical Field

[0001] This invention relates to the field of conveying devices, and more particularly to a conveying device for plastic granules. Background Technology

[0002] Conveying devices for plastic granules are mainly used for the continuous and efficient conveying of plastic granules, and are widely used in industries such as plastics processing, chemicals, ceramics, and steel metallurgy, providing these industries with a reliable supply of raw materials.

[0003] Patent application number 202310105840.3 discloses a conveying device for plastic granules, including a conveyor, a protective cover, and a pushing assembly. The conveyor belt has several evenly arranged through holes. The pushing assembly includes a motor bracket fixedly installed on the upper part of the protective cover. A second motor is installed on the motor bracket. A cam is connected to the output shaft end of the second motor. A drive frame is also provided on the upper part of the protective cover. The cam is located inside the drive frame. Slide rods are fixedly connected to both sides of the drive frame. Supports are provided on both sides of the upper part of the protective cover. The slide rods are slidably installed inside the supports. Connecting frames are fixedly connected to both ends of the slide rods.

[0004] During the conveying process, plastic granules may be unevenly distributed. In particular, after water-cooled pelletizing, the uneven humidity of the plastic granules makes them prone to adhering to the surface of the conveying device, resulting in uneven discharge. When entering the packaging bag, this may cause some areas to be too dense with granules, while other areas are sparse. This not only affects the appearance of the packaging bag, but may also cause uneven weight of the plastic granules inside the bag, affecting the accuracy of measurement. In subsequent production processes, such as plasticizing and extrusion, it may also affect the quality and output of the product. Summary of the Invention

[0005] This invention discloses a conveying device for plastic granules, aiming to solve the problem of uneven distribution of plastic granules during the conveying process. In particular, after water-cooled pelletizing, the uneven humidity of the plastic granules makes them prone to adhering to the surface of the conveying device, resulting in uneven discharge. When entering the packaging bag, this may cause some areas to be too dense with granules, while other areas are sparse. This not only affects the appearance of the packaging bag, but may also cause uneven weight of plastic granules inside the packaging bag, affecting the accuracy of measurement. In subsequent production processes, such as plasticizing and extrusion, it may also affect the quality and output of the product.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A conveying device for plastic granules includes two mounting plates, each with a support frame near its four corners on both sides. The top and bottom outer walls of each mounting plate are provided with mounting frames. A conveyor connects the two mounting plates. The device further includes:

[0008] Air blowing mechanism: Located at the top of one of the mounting frames, the air blowing mechanism includes three limiting frame plates. The interior of each limiting frame plate includes three second micro air pumps. The top inner wall of the mounting frame has four equally spaced fixing frames. The bottom outer wall of each fixing frame has a partition. One side inner wall of one of the fixing frames has four first motors and four limiting rotating rods. The output shaft of each first motor is fixedly connected to a limiting rod. One end of each limiting rod is connected to the outer wall of one side of the fixing frame via a bearing. The circumferential outer wall of the limiting rod and the limiting rotating rod... The outer circumferential wall is provided with a first sector-shaped toothed plate and a second sector-shaped toothed plate respectively. The teeth of the first sector-shaped toothed plate and the teeth of the second sector-shaped toothed plate mesh with each other. One end of the limiting rotating rod is fixedly connected to the inner wall of one of the fixed frames. Three wind hoods are fixedly connected between two adjacent partitions and on the outer circumferential wall of the limiting rotating rod. The bottom of the second micro air pump is provided with an exhaust port. The inner wall of the exhaust port is provided with two exhaust pipes. One end of the two exhaust pipes is connected to the top of the two wind hoods respectively. The inside of the wind hood is provided with a heating wire.

[0009] Guiding mechanism: located on the upper surface of the conveyor;

[0010] Dust removal mechanism: located on the bottom outer wall of the two mounting plates;

[0011] Vacuuming mechanism: located directly above the guide mechanism;

[0012] Pushing mechanism: located on the top outer wall of the two mounting plates.

[0013] During plastic granule conveying, the conveyor and the second micro air pumps within the three limit frames are started, simultaneously activating the four first motors. The bottom end of the partition plate is in contact with the upper surface of the conveyor, dividing the upper surface into five discharge zones. When the output shaft of the first motor drives the limit rod to rotate, it in turn drives the first sector toothed plate to rotate. Since the first and second sector toothed plates always partially overlap and mesh, this drives the limit rotating rod to rotate. The air shroud on the limit rotating rod swings back and forth, increasing the blowing range of the air shroud. The second micro air pump draws external air into the air shroud through two exhaust pipes, and the air is heated by heating wires inside the air shroud. The heated air is blown onto the plastic granules on the conveyor, thus using the high-temperature gas to circulate and push the plastic granules back and forth, extending the time the plastic granules spend drying on the conveyor surface and accelerating the evaporation of moisture from the surface of the plastic granules. This prevents the plastic granules from adhering to the conveyor surface. At the same time, the guiding mechanism guides and quickly diverts the plastic granules. This device can improve the uniformity of the distribution of plastic granules, reduce the agglomeration or adhesion of plastic granules caused by uneven humidity, and make the density of plastic granules in the packaging bag more consistent, improving the appearance of the packaging bag and also improving the conveying efficiency of plastic granules.

[0014] In a preferred embodiment, the guiding mechanism includes four guide brushes, one of which has an installation opening on the top outer wall of the mounting frame. The inner wall of the mounting opening is provided with a limiting plate, and three connecting rods are provided between the limiting plate and the guide brush. One outer wall of the mounting plate is provided with a material guide frame, and the top outer wall of the material guide frame is provided with five material guide plates. A material guide channel is formed between two adjacent material guide plates. The position of the guide brush corresponds to the material guide channel, and one side of the material guide frame abuts against the material inlet of the conveyor.

[0015] This setup ensures that plastic granules are guided and adjusted by the guide brush as they pass through the feed channel, preventing them from shifting or scattering during transport. Especially when used in conjunction with a conveyor, one side of the guide frame abuts against the feed port of the conveyor, allowing the plastic granules to smoothly enter the conveyor from the feed channel, thus achieving efficient transport. This reduces the likelihood of plastic granules agglomerating and clumping together, which could lead to some areas being too densely packed with granules while others are sparsely packed.

[0016] In a preferred embodiment, the vacuuming mechanism includes three sets of fixing components. The three sets of fixing components are located on the inner wall of opposite sides of the mounting port and on the top inner wall of the mounting frame. Each fixing component includes two support blocks, with a ring between the two support blocks. The top outer wall of the ring is connected to a gear ring via a bearing. The top outer wall of the support block is provided with a fixing plate. One outer wall of the fixing plate is provided with a micro motor. The output shaft of the micro motor is fixedly connected to a gear, which meshes with the teeth on the gear ring. One outer wall of the gear is provided with a first support rod. One end of the first support rod is hinged to a second support rod. One end of the two second support rods is provided with a vacuum box. The vacuum box contains a first micro air pump. The bottom of the first micro air pump is provided with a connecting pipe. One end of the connecting pipe is provided with three vacuum pipes. One end of the three vacuum pipes is provided with a vacuum plate. Both outer walls of the vacuum plate are provided with several vacuum ports.

[0017] In use, the micro motor is activated, and its output shaft drives the gear and the first support rod to rotate. Because the gear meshes with the teeth on the gear ring, the gear's rotation pushes the gear ring to rotate on the circular surface. With the coordinated action of the first and second support rods, the dust collection box moves in a straight up-and-down reciprocating motion. When the first and second support rods move the dust collection box downwards, the dust collection plate moves downwards simultaneously and comes into contact with and rubs against one side of the outer wall of the two guide brushes. Using the first micro air pump, dust is sucked out from the surface of the guide brushes through three suction pipes and multiple suction ports. This reduces dust accumulation on the guide brush surface as plastic particles pass through, preventing dust buildup that can clog the brush bristles, reduce the contact area between the guide brush and the plastic particles, and consequently decrease the wiping and cleaning effect, affecting the transport and processing of subsequent batches of plastic particles.

[0018] In a preferred embodiment, the pushing mechanism includes two fixed blocks. One outer wall of each fixed block is provided with an electric telescopic rod. The movable end of the electric telescopic rod is provided with a mounting rod. The top outer walls of the two mounting plates are hinged with several guide plates. One end of the mounting rod passes through one outer wall of the several guide plates. A guide block is provided on the circumferential outer wall of the mounting rod and between two adjacent guide plates.

[0019] Before use, the movable end of the electric telescopic rod drives the mounting rod to retract to the left. At this time, the guide block pushes several guide plates to tilt to the left. During use, the movable end of the electric telescopic rod drives the mounting rod to extend to the right. At this time, the guide block pushes several guide plates to tilt to the right. By controlling the extension and retraction of the electric telescopic rod, the movement of the mounting rod can be precisely controlled, which also enhances the stability and smoothness of the material pushing. The guide plates set on the conveyor facilitate the precise pushing and positioning of plastic granules, while preventing plastic granules near the inner walls of both sides of the mounting frame from accumulating during the conveying process, reducing blockages and malfunctions during the conveying process, thereby improving the conveying efficiency of plastic granules.

[0020] In a preferred embodiment, the dust removal mechanism includes a scraper. The bottom outer walls of both mounting plates are provided with a first limiting frame and a second limiting frame. A groove is formed on one side of the outer wall of both the first and second limiting frames. Two sliders are provided on both sides of the outer wall of the scraper. Two sliders on the same side are slidably connected to the inner walls of the two grooves. A first return spring and a second return spring are respectively provided on the bottom outer walls of the two sliders. A second screw and a first screw are respectively threaded to the bottom of the first and second limiting frames. A second limiting plate is connected to one end of the second screw via a bearing, and a first limiting plate is connected to one end of the first screw via a bearing. One end of the first and second return springs are respectively fixedly connected to the top outer walls of the first and second limiting plates.

[0021] During the conveying process, plastic granules inevitably carry some dust. Although some of the dust is wiped away by the guide brush, the remaining dust is dried and diverted by the air blowing mechanism, naturally falling onto the conveyor surface. Since the first and second return springs are connected to the first and second limiting plates respectively, the operator can rotate the first and second screws to move the first and second limiting plates up and down along the grooves within the second and first limiting frames, thereby adjusting the compression of the first and second return springs and controlling the distance between the first and second limiting plates and the slider on the scraper. Due to the design of the slider and groove, the scraper is easy to disassemble and replace when needed, reducing maintenance costs and difficulty. This design facilitates adjusting the fit and pressure between one end of the scraper and the lower surface of the conveyor to adapt to different conveyor surfaces and dust removal requirements. Fallen dust and adhered plastic granules are scraped off by the scraper and fall into the inner wall of the mounting frame located below the conveyor, thus preventing plastic granules from adhering to the conveyor for extended periods and affecting the conveying of other plastic granules.

[0022] As can be seen from the above, a conveying device for plastic granules includes two mounting plates, each with a support frame near its four corners on both sides. The top and bottom outer walls of each mounting plate are provided with mounting frames. A conveyor between the two mounting plates further includes:

[0023] Air blowing mechanism: Located at the top of one of the mounting frames, the air blowing mechanism includes three limiting frame plates. The interior of each limiting frame plate includes three second micro air pumps. The top inner wall of the mounting frame has four equally spaced fixing frames. The bottom outer wall of each fixing frame has a partition. One side inner wall of one of the fixing frames has four first motors and four limiting rotating rods. The output shaft of each first motor is fixedly connected to a limiting rod. One end of each limiting rod is connected to the outer wall of one side of the fixing frame via a bearing. The circumferential outer wall of the limiting rod and the limiting rotating rod... The outer circumferential wall is provided with a first sector-shaped toothed plate and a second sector-shaped toothed plate respectively. The teeth of the first sector-shaped toothed plate and the teeth of the second sector-shaped toothed plate mesh with each other. One end of the limiting rotating rod is fixedly connected to the inner wall of one of the fixed frames. Three wind hoods are fixedly connected between two adjacent partitions and on the outer circumferential wall of the limiting rotating rod. The bottom of the second micro air pump is provided with an exhaust port. The inner wall of the exhaust port is provided with two exhaust pipes. One end of the two exhaust pipes is connected to the top of the two wind hoods respectively. The inside of the wind hood is provided with a heating wire.

[0025] Dust removal mechanism: located on the bottom outer wall of the two mounting plates;

[0026] Vacuuming mechanism: located directly above the guide mechanism;

[0027] Pushing mechanism: Located on the top outer wall of the two mounting plates. The conveying device for plastic granules provided by the present invention has the technical effect of improving the uniformity of plastic granule distribution, reducing the agglomeration or adhesion of plastic granules caused by uneven humidity, making the density of plastic granules in the packaging bag more consistent, improving the appearance of the packaging bag, and also improving the conveying efficiency of plastic granules.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0041] The plastic granule conveying device disclosed in this invention is mainly used when plastic granules are unevenly distributed during the conveying process. In particular, after water-cooled pelletizing, the plastic granules are prone to sticking to the surface of the conveying device due to uneven humidity, resulting in uneven discharge. When entering the packaging bag, some areas may have excessively dense granules while other areas are sparse. This not only affects the appearance of the packaging bag but may also cause uneven weight of the plastic granules inside the bag, affecting the accuracy of measurement. In subsequent production processes, such as plasticizing and extrusion, it may also affect the quality and output of the product.

[0042] Reference Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8 A conveying device for plastic granules includes two mounting plates 2, with support frames 3 located near the four corners on both sides of each mounting plate 2. Mounting frames 1 are provided on the top and bottom outer walls of each mounting plate 2. A conveyor connects the two mounting plates 2. The device also includes:

[0043] Air blowing mechanism: Located at the top of one of the mounting frames 1, the air blowing mechanism includes three limiting frame plates 7. The interior of the limiting frame plate 7 includes three second micro air pumps. The top inner wall of the mounting frame 1 is provided with four equally spaced fixing frames 40. The bottom outer wall of the fixing frame 40 is provided with a partition plate 14. One side inner wall of one of the fixing frames 40 is provided with four first motors 43 and four limiting rotating rods 45. The output shaft of the first motor 43 is fixedly connected to the limiting rod. One end of the limiting rod is connected to the outer wall of one side of the fixing frame 40 through a bearing. The outer circumference of the limiting rod and the outer circumference of the limiting rotating rod 45 are connected. The wall is provided with a first sector tooth plate 44 and a second sector tooth plate 46 respectively. The teeth of the first sector tooth plate 44 and the teeth of the second sector tooth plate 46 mesh with each other. One end of the limiting rotating rod 45 is fixedly connected to the inner wall of one side of one of the fixed frames 40. Three wind hoods 16 are fixedly connected between two adjacent partitions 14 and on the outer circumference of the limiting rotating rod 45. The bottom of the second micro air pump is provided with an exhaust port. The inner wall of the exhaust port is provided with two exhaust pipes 13. One end of the two exhaust pipes 13 is connected to the top of the two wind hoods 16 respectively. The inside of the wind hood 16 is provided with a heating wire 17.

[0044] Guiding mechanism: Located on the upper surface of the conveyor;

[0045] Dust removal mechanism: located on the bottom outer wall of the two mounting plates 2;

[0046] Vacuuming mechanism: Located directly above the guide mechanism;

[0047] Pushing mechanism: located on the top outer wall of the two mounting plates 2.

[0048] The partition 14 has several equally spaced mounting holes 15 on one outer wall, and the air outlet of the hood 16 has a fan-shaped structure. Because the partition 14 has several equally spaced mounting holes 15, when the high-temperature gas inside the hood 16 is blown out, these mounting holes 15 ensure that the gas is evenly distributed in the space. This allows the high-temperature gas to quickly dry the plastic particles near the discharge area on both sides of the mounting frame 1, preventing uneven surface humidity of these plastic particles from causing them to adhere to the conveyor surface and affect the uniformity of the discharge distribution. The air outlet of the fan shroud 16 is designed in a fan shape. This design allows the blown high-temperature gas to spread in a fan shape, thereby covering a wider area. Compared with a straight air outlet, the fan-shaped air outlet can more effectively cover the target area and reduce dead corners. The fan shroud 16 is provided between two adjacent partitions 14. This design allows the high-temperature gas to move continuously in the space, avoiding the gas from staying in a certain area for a long time and causing local overheating. At the same time, the fan shroud 16 can also increase the contact area between the high-temperature gas and the plastic particles, improving the heating efficiency.

[0049] It should be noted that the first sector tooth plate 44 and the second sector tooth plate 46 have the same radius and their meshing parts are the same. The first sector tooth plate 44 and the second sector tooth plate 46 have a certain included angle θ in the initial position. When the first sector tooth plate 44 rotates α degrees, in order to ensure that the teeth of the first sector tooth plate 44 and the second sector tooth plate 46 overlap and mesh, the second sector tooth plate 46 only needs to rotate α-θ degrees and θ<α to maintain meshing. In practical applications, it may be necessary to adjust according to the specific sector tooth plate size, tooth shape and rotation speed.

[0050] Specifically, during the conveying of plastic granules, the conveyor and the second micro air pumps inside the three limiting frame plates 7 are started, and the four first motors 43 are started simultaneously. The bottom end of the partition plate 14 is attached to the upper surface of the conveyor, thereby dividing the upper surface of the conveyor into five discharge areas. When the output shaft of the first motor 43 drives the limiting rod to rotate, it drives the first sector toothed plate 44 to rotate. Since the first sector toothed plate 44 and the second sector toothed plate 46 always have partial overlap and meshing, it drives the limiting rotating rod 45 to rotate. The wind shroud 16 on the limiting rotating rod 45 swings back and forth, thereby increasing the blowing range of the wind shroud 16. The second micro air pump draws external air into the wind shroud 16 through two exhaust pipes 13. The heating wire 17 inside heats the air and blows it onto the plastic granules on the conveyor. This uses high-temperature gas to circulate and push the plastic granules back and forth on the conveyor, extending the drying time of the plastic granules on the conveyor surface and accelerating the evaporation of moisture from the surface of the plastic granules. This prevents the plastic granules from adhering to the conveyor surface. At the same time, the guiding mechanism guides and quickly diverts the plastic granules and can also absorb some of the moisture on the surface of the granules. Thus, the high-temperature gas dries and dehumidifies the plastic granules while limiting and guiding them, reducing the adhesion of plastic granules due to uneven humidity. This reduces the occurrence of uneven material discharge caused by plastic granules adhering to the surface of the conveyor.

[0051] Reference Figure 1 and Figure 5 In a preferred embodiment, the guiding mechanism includes four guide brushes 36. One of the mounting frames 1 has an installation opening on its top outer wall. The inner wall of the installation opening is provided with a limiting plate 6. Three connecting rods 8 are provided between the limiting plate 6 and the guide brushes 36. One outer wall of the mounting plate 2 is provided with a material guide frame 4. The top outer wall of the material guide frame 4 is provided with five material guide plates 5. A material guide channel is formed between two adjacent material guide plates 5. The position of the guide brushes 36 corresponds to the material guide channel. One side of the material guide frame 4 abuts against the material inlet of the conveyor.

[0052] The guide brush 36 has a "U" shaped structure, with connecting brackets at both ends. The connecting brackets are fixedly connected to one outer wall of the partition 14. The connecting brackets have a "Y" shaped structure. When the plastic granules move on the conveyor belt 12, they will come into contact with the guide brush 36 and be guided, ensuring that the granules can be conveyed along the predetermined path. The "Y" shaped connecting brackets fix the guide brush 36 to the partition 14, which can enhance the stability of the guide brush 36. The guide brush 36 divides the plastic granules into multiple parts, which facilitates the smooth conveying of the plastic granules and reduces the occurrence of blockages, downtime and other failures, thereby improving the operating efficiency of the entire production line.

[0053] Specifically, when plastic granules pass through the guide channel, they are guided and adjusted by the guide brush 36 to prevent them from shifting or scattering during transmission. Especially when used in conjunction with a conveyor, one side of the guide frame 4 abuts against the conveyor's feed port, allowing the plastic granules to smoothly enter the conveyor from the guide channel, thereby achieving efficient transmission and reducing the occurrence of situations where some areas are too densely packed with granules while other areas are relatively sparse due to the aggregation and adhesion of plastic granules.

[0054] Reference Figure 4 and Figure 5 In a preferred embodiment, the vacuuming mechanism includes three sets of fixing components. The three sets of fixing components are located on the inner wall of the opposite side of the mounting port and on the top inner wall of the mounting frame 1. The fixing components include two support blocks 20, and a ring 21 is provided between the two support blocks 20. The top outer wall of the ring 21 is connected to a gear ring through a bearing. The top outer wall of the support block 20 is provided with a fixing plate. One outer wall of the fixing plate is provided with a micro motor 22. The output shaft of the micro motor 22 is fixedly connected to a gear 23. The gear 23 meshes with the teeth on the gear ring. One outer wall of the gear 23 is provided with a first support rod 24. One end of the first support rod 24 is hinged to a second support rod 25. One end of the two second support rods 25 is provided with a vacuum box 19. The vacuum box 19 is provided with a first micro air pump. The bottom of the first micro air pump is provided with a connecting pipe. One end of the connecting pipe is provided with three vacuum pipes 18. One end of the three vacuum pipes 18 is provided with a vacuum plate 35. Several vacuum ports are opened on both outer walls of the vacuum plate 35.

[0055] In the specific implementation process, the dust suction plate 35 is located between two adjacent guide brushes 36, and the two sides of the dust suction plate 35 are respectively attached to one side of the outer wall of the two guide brushes 36. Both sides of the dust suction plate 35 are inclined downward.

[0056] Specifically, in use, the micro motor 22 is activated, and the output shaft of the micro motor 22 drives the gear 23 and the first support rod 24 to rotate. Since the gear 23 meshes with the teeth on the gear ring, the rotation of the gear 23 pushes the gear ring to rotate on the surface of the ring 21. Under the coordinated use of the first support rod 24 and the second support rod 25, the dust collection box 19 makes a linear up-and-down reciprocating motion. When the first support rod 24 and the second support rod 25 drive the dust collection box 19 to move downward, the dust collection plate 35 moves downward synchronously and comes into contact with and rubs against one side of the outer wall of the two guide brushes 36. With the use of the first micro air pump, dust on the surface of the guide brush 36 is sucked out through three suction pipes 18 and multiple suction ports. This reduces the amount of dust adhering to the surface of the guide brush 36 while it is wiping away moisture from the plastic particles. If this dust is not cleaned in time, it may accumulate and clog the bristles of the guide brush 36, reducing the contact area between the guide brush 36 and the plastic particles, thereby reducing its wiping and cleaning effect and affecting the conveying and processing of the next batch of plastic particles.

[0057] Reference Figure 2 , Figure 6 and Figure 9 In a preferred embodiment, the pushing mechanism includes two fixed blocks 9. One outer wall of the fixed block 9 is provided with an electric telescopic rod 10. The movable end of the electric telescopic rod 10 is provided with a mounting rod 37. The top outer walls of the two mounting plates 2 are hinged with a plurality of guide plates 38. One end of the mounting rod 37 passes through one outer wall of the plurality of guide plates 38. A guide block 39 is provided on the circumferential outer wall of the mounting rod 37 and between two adjacent guide plates 38.

[0058] One end of the guide block 39 has a "Y" shape, and the outer wall of one side of the guide plate 38 is provided with a semi-circular protrusion. The "Y" shaped guide block 39 facilitates the left and right tilting and rotation of the guide plate 38 under the extension and retraction of the movable end of the electric telescopic rod 10. The semi-circular protrusion can block the gap between two adjacent guide plates 38, thereby preventing the guide plate 38 from getting stuck with the plastic particles during the movement, ensuring the continuity and stability of the conveying process. At the same time, the contact surface between the semi-circular protrusion and the plastic particles is arc-shaped. Compared with the flat contact, the arc-shaped contact can reduce friction, making the plastic particles smoother during conveying.

[0059] Specifically, before use, the movable end of the electric telescopic rod 10 drives the mounting rod 37 to retract to the left. At this time, the guide block 39 pushes several guide plates 38 to tilt to the left. During use, the movable end of the electric telescopic rod 10 drives the mounting rod 37 to extend to the right. At this time, the guide block 39 pushes several guide plates 38 to tilt to the right, thereby pushing the clumps of plastic granules. By controlling the extension and retraction of the electric telescopic rod 10, the movement of the mounting rod 37 can be precisely controlled, which also enhances the stability and smoothness of the material pushing. The guide plates 38 set on the conveyor facilitate the precise pushing and positioning of the plastic granules, while preventing the plastic granules near the inner walls of both sides of the mounting frame 1 from accumulating during the conveying process, reducing blockages and malfunctions during the conveying process, thereby improving the conveying efficiency of the plastic granules.

[0060] Reference Figure 2 , Figure 10 and Figure 11 In a preferred embodiment, the dust removal mechanism includes a scraper 26. The bottom outer walls of the two mounting plates 2 are provided with a first limiting frame 27 and a second limiting frame 28. The outer walls of the first limiting frame 27 and the second limiting frame 28 are provided with a sliding groove on one side. The outer walls of both sides of the scraper 26 are provided with two sliders. The two sliders on the same side are slidably connected to the inner walls of the two sliding grooves. The bottom outer walls of the two sliders are respectively provided with a first return spring 32 and a second return spring 34. The bottoms of the first limiting frame 27 and the second limiting frame 28 are respectively connected to a second screw 30 and a first screw 29 by threads. One end of the second screw 30 is connected to a second limiting piece 33 by a bearing. One end of the first screw 29 is connected to a first limiting piece 31 by a bearing. One end of the first return spring 32 and the second return spring 34 are respectively fixedly connected to the top outer walls of the first limiting piece 31 and the second limiting piece 33.

[0061] Specifically, during the conveying process, the plastic granules themselves carry some dust. Although some of the plastic granules have some dust wiped off when passing through the guide brush 36, the dust on the plastic granules themselves naturally falls onto the surface of the conveyor after being dried and diverted by the air blowing mechanism. Since the first return spring 32 and the second return spring 34 are respectively connected to the first limiting plate 31 and the second limiting plate 33, the operator can adjust the first return spring by rotating the first screw 29 and the second screw 30, which drives the first limiting plate 31 and the second limiting plate 33 to move up and down in the sliding grooves within the second limiting frame 28 and the first limiting frame 27. The compression degree of the first limiting plate 31, the second limiting plate 33 and the slider on the scraper 26 are controlled by the compression degree of the second return spring 34. Due to the design of the slider and the groove, the scraper 26 is easy to disassemble and replace when needed, reducing maintenance costs and difficulty. This design makes it easy to adjust the fit and pressure between one end of the scraper 26 and the lower surface of the conveyor to adapt to different conveyor surfaces and dust removal requirements. Fallen dust and adhered plastic particles are scraped off by the scraper 26 and fall into the inner wall of the bottom of the mounting frame 1 located below the conveyor, thereby avoiding plastic particles from adhering to the conveyor for a long time and affecting the conveying of other plastic particles.

[0062] Reference Figure 2 and Figure 9 In a preferred embodiment, the conveyor includes two mounting rollers 11, and a geared motor 42 is provided on one side of the outer wall of the mounting plate 2. One end of one mounting roller 11 is fixedly connected to the output end of the geared motor 42. The outer circumferential walls of the two mounting rollers 11 are provided with a conveyor belt 12, and the surface of the conveyor belt 12 is provided with a plurality of evenly distributed through holes.

[0063] It should be noted that the inner diameter of several through holes is smaller than the diameter of the plastic granules.

[0064] Specifically, in use, since the two mounting rollers 11 are mounted between the two mounting plates 2 via bearings, when one of the mounting rollers 11 is driven to rotate by the output shaft of the geared motor 42, the conveyor belt 12 will form a closed loop between the two mounting rollers 11 and move continuously as the mounting rollers 11 rotate. The plastic granules are placed on the upper surface of the moving conveyor belt 12 and move with the conveyor belt 12. Through holes are opened on the surface of the conveyor belt 12. This setting makes it easy for the through holes to prevent the plastic granules from leaking out, while also effectively promoting the evaporation of moisture on the surface of the plastic granules. When used in conjunction with the air blowing mechanism, it helps to reduce the phenomenon of plastic granules sticking together due to uneven humidity.

[0065] Working principle: When conveying plastic granules, the conveyor and the second micro air pumps inside the three limit frame plates 7 are started, and the four first motors 43 are started simultaneously. The bottom end of the partition plate 14 is attached to the upper surface of the conveyor, thereby dividing the upper surface of the conveyor into five discharge areas. When the output shaft of the first motor 43 drives the limit rod to rotate, it drives the first sector toothed plate 44 to rotate. Since the first sector toothed plate 44 and the second sector toothed plate 46 always have partial overlap and meshing, it drives the limit rotating rod 45 to rotate. The wind shroud 16 on the limit rotating rod 45 swings back and forth, thereby increasing the blowing range of the wind shroud 16. The second micro air pump draws external air into the wind shroud 16 through two exhaust pipes 13. The heating wire 17 inside the 6 heats the air and blows it onto the plastic granules on the conveyor. This uses high-temperature gas to circulate and push the plastic granules back and forth on the conveyor, extending the drying time of the plastic granules on the conveyor surface and accelerating the evaporation of moisture from the surface of the plastic granules. This prevents the plastic granules from adhering to the conveyor surface. At the same time, the set guiding mechanism guides and quickly diverts the plastic granules and can also absorb some of the moisture on the surface of the granules. Thus, the high-temperature gas dries and dehumidifies the plastic granules while limiting and guiding them, reducing the adhesion of plastic granules due to uneven humidity. This reduces the occurrence of uneven material discharge caused by plastic granules adhering to the surface of the conveyor.
