Description

Technical Field

[0001] This invention relates to the field of material conveying technology, specifically to a granular material conveying device for granulation production. Background Technology

[0002] Currently, in the granulation production processes of plastics, chemicals, feed and various polymer materials, after the materials are melted, extruded, granulated and cooled and solidified, they usually need to be transferred to the packaging station by a conveying device for bagging and sealing, so as to facilitate subsequent storage, transportation and sales. With the continuous improvement of the speed of automated production lines, higher requirements are placed on the conveying efficiency, feeding stability and bagging continuity of granular materials.

[0003] A search revealed that patent CN222714632U discloses a belt conveyor for easy-to-operate bulk material conveying. This patent uses a hopper to transport materials onto the conveyor, and then uses the conveyor to directly transport granular materials to the bagging station for continuous feeding and bagging. However, in actual production, operations such as bag replacement require a certain amount of time. The speed of manual or automated bag changing is difficult to match the continuous conveying speed of the conveyor. During bag changing intervals, if the conveyor continues to run, the material will fall without support, causing spillage. Furthermore, existing technologies also... A storage tank is installed at the end of the conveyor. The granular material is first transported into the storage tank for temporary storage. Then, the intermittent feeding and bagging are achieved by controlling the opening and closing of the discharge port at the bottom of the storage tank. Although this method can alleviate the matching problem between bag changing and continuous conveying to a certain extent, the material accumulates in a large amount in the storage tank. The particles at the bottom are subjected to the pressure of the material above for a long time, which can easily lead to caking, sticking, and agglomeration. This not only causes poor material discharge and local pipe blockage, but also damages the integrity of the particles and affects product quality. At the same time, the accumulated material is prone to uneven density and segregation, resulting in a large deviation in bag weight. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a granular material transportation device for granulation production, which can ensure continuous material transportation and switch bagging stations by rotating the conveying pipe.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a granular material conveying device for granulation production, comprising:

[0006] The conveyor includes an inlet end and an outlet end;

[0007] A feeding assembly is installed at the feed end of the conveyor, and the feeding assembly is used to convey particulate materials to the conveyor;

[0008] The discharge assembly includes a discharge hood disposed on the discharge end of the conveyor and a conveying pipe rotatably disposed on the discharge hood. The bottom of the discharge hood is provided with a blocking surface and at least two discharge ports on a circumference centered on the axis of the discharge hood.

[0009] A switching drive component is installed on the discharge hood, and the switching drive component is connected to the conveying pipe to drive the conveying pipe to rotate about the axis of the discharge hood; wherein...

[0010] The conveying pipe has a discharge position and a blocking position during rotation. When the conveying pipe rotates to the discharge position, the outlet of the conveying pipe connects with the corresponding discharge port. The conveying pipe is used to discharge the material entering the discharge hood to the discharge port after connecting with the corresponding discharge port. When the conveying pipe rotates to the blocking position, the blocking surface blocks the outlet of the conveying pipe.

[0011] Furthermore, in order to disturb the material temporarily stored in the conveying pipe, multiple air holes are provided on the blocking surface to connect the inner cavity of the discharge hood with the outside. A gas collecting hood is connected to the discharge hood. The gas collecting hood is used to cover all the air holes, and the inner cavity of the gas collecting hood is connected to the air holes. The gas collecting hood is connected to a gas supply device.

[0012] When the conveying pipe rotates to the blocking position, the gas generated by the gas supply device first passes through the gas collecting hood and then through the air hole into the conveying pipe to disturb the material in the conveying pipe.

[0013] Furthermore, a shielding member is connected to the outlet of the conveying pipe, which is arranged circumferentially with the blocking surface and does not block the outlet of the conveying pipe. The shielding member abuts against the blocking surface. When the conveying pipe rotates to the blocking position, the shielding member is adapted to block all the air holes except the air hole corresponding to the position of the outlet of the conveying pipe.

[0014] Furthermore, to prevent excessive material discharge from scattering or causing excessive weight deviation after bagging, the discharge hood is equipped with a material buffer component corresponding to the discharge port. The material buffer component includes:

[0015] Rotate the buffer cover bowl mounted on the discharge hood. The buffer cover bowl has an upper position and a lower position. When the buffer cover bowl is rotated to the lower position, the buffer cover bowl does not obstruct the corresponding discharge port. When the buffer cover bowl is rotated to the upper position, the opening of the buffer cover bowl covers the corresponding discharge port.

[0016] A buffer drive component is installed on the discharge cover, and the buffer drive component is connected to the buffer cover bowl to drive the buffer cover bowl to rotate.

[0017] Furthermore, in order to better discharge the material inside the buffer bowl, a guide portion is inclinedly provided inside the buffer bowl, and the guide portion gradually tilts downward from the direction away from the rotation center to the direction closer to the rotation center.

[0018] Furthermore, in order to better gather the dispersed materials at the discharge hood during the conveying process, the conveyor is equipped with a material gathering component. The material gathering component includes two limiting plates that are arranged opposite each other on both sides of the conveyor and are inclined. The two limiting plates are used to gather the particulate materials on the conveyor and then let them enter the discharge hood.

[0019] Furthermore, to reduce the impact of materials on the conveyor, the feeding assembly includes:

[0020] A feeding hood connected to the conveyor has a feeding inlet at the top and a feeding outlet at the bottom.

[0021] At least one disturbance component is disposed within the feeding hood, the disturbance component including a flexible component, the flexible component including multiple sets of vertically spaced flexible buffer discs;

[0022] The feeding hood is provided with a separated working area and a blocking area. The flexible buffer disc shuttles between the working area and the blocking area during rotation. The working area is used to connect the feed inlet and the discharge outlet. The blocking area is used to prevent the material on the flexible buffer disc from entering the blocking area. When the material enters the working area through the feed inlet and is discharged to the conveyor through the discharge outlet, the material comes into contact with the flexible buffer disc. The flexible buffer disc is suitable for reducing the impact force when the material falls.

[0023] The disturbance component further includes a rotation drive component, which is connected to the corresponding flexible component to drive the multiple flexible buffer disks in the flexible component to rotate, thereby causing different sections of the flexible buffer disks in the circumferential direction to alternately shuttle between the working area and the barrier area.

[0024] Furthermore, to avoid excessive material agglomeration, two disturbance components are provided inside the feeding hood. The two disturbance components are arranged symmetrically, and the flexible buffer discs in the two disturbance components are staggered along the axial direction of the feeding hood. The flexible buffer discs in the two disturbance components are configured to rotate in opposite directions under the action of the corresponding rotary drive component.

[0025] Furthermore, to prevent damage to the flexible buffer disk, a barrier element corresponding to the flexible component is provided in the barrier area, and the barrier element has multiple recovery chambers corresponding to the flexible buffer disk.

[0026] Furthermore, to prevent material blockage, the flexible buffer tray includes multiple circumferentially arranged sector-shaped trays, with disconnected channels between adjacent sector-shaped trays.

[0027] By adopting the above technical solution, the present invention has the following beneficial effects:

[0028] 1. A bagging station corresponding to the discharge port is set below the discharge hood. When there are two discharge ports, there are two corresponding bagging stations. The two bagging stations are referred to as the first station and the second station. The material falls onto the conveyor through the feeding component and is moved to the discharge hood by the conveyor. The material enters the conveying pipe through the discharge hood. When the conveying pipe is aligned with one of the discharge ports, the material is discharged through the discharge port and bagged at the first station. When the first station completes bagging and starts changing bags, the switching drive unit is started, which drives the conveying pipe to rotate to align with the other discharge port and discharges the internal material to the second station through the other discharge port to complete the bagging. At this time, the second station starts changing bags. The switching drive unit is started again, which makes the conveying pipe rotate to the first station. The bag changing at the first station is completed when bagging is carried out at the second station. Repeating the above steps can realize continuous switching of multiple stations, ensuring that the conveyor can continuously transport materials without waiting for bag changing time or setting up intermediate material tanks.

[0029] 2. After the first station completes the bagging work, the switching drive unit starts and drives the conveying pipe to rotate to the second station. At the same time as the switching drive unit starts, the buffer drive unit at the first station starts synchronously and drives the buffer cover bowl at the first station to move from the lower position to the upper position, covering the discharge port corresponding to the first station that has completed the bagging work. This collects the excess material discharged and prevents the material discharged from the discharge port of the conveying pipe from scattering into the first station or into the bag at the first station before it has fully rotated to contact the blocking surface (i.e., the discharge port is not completely blocked), which would cause the material in the bag to have an excessive weight deviation.

[0052] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0053] Example 1: As Figure 1-3 As shown, a granular material conveying device for granulation production includes:

[0054] Conveyor 1, which includes an inlet end and an outlet end;

[0055] A feeding assembly 2 is installed at the feed end of conveyor 1, and the feeding assembly 2 is used to convey granular materials to conveyor 1.

[0056] The discharge assembly 3 includes a discharge cover 31 disposed on the discharge end of the conveyor 1 and a conveying pipe 32 rotatably disposed on the discharge cover 31. The bottom of the discharge cover 31 is provided with a blocking surface 34 and at least two discharge ports 33 on a circumference with the axis of the discharge cover 31 as the center.

[0057] A switching drive component 4 is installed on the discharge hood 31. The switching drive component 4 is connected to the conveying pipe 32 to drive the conveying pipe 32 to rotate around the axis of the discharge hood 31.

[0058] The conveying pipe 32 has a discharge position and a blocking position during rotation. When the conveying pipe 32 rotates to the discharge position, the discharge port of the conveying pipe 32 connects to the corresponding discharge port 33. The conveying pipe 32 is used to discharge the material entering the discharge hood 31 to the discharge port 33 after connecting to the corresponding discharge port 33. When the conveying pipe 32 rotates to the blocking position, the blocking surface 34 blocks the discharge port of the conveying pipe 32.

[0059] In this embodiment, a bagging station corresponding to the discharge port 33 is provided below the discharge hood 31. When there are two discharge ports 33, there are two corresponding bagging stations. These two bagging stations are referred to as the first station and the second station. The material falls onto the conveyor 1 through the feeding component 2 and is moved into the discharge hood 31 by the conveyor 1. The material enters the conveying pipe 32 through the discharge hood 31. When the conveying pipe 32 is aligned with one of the discharge ports 33, the material is discharged through the discharge port 33 and then bagged at the first station. After the first station completes bagging, the material is then... When changing bags, the switching drive unit 4 is started, which drives the conveying pipe 32 to rotate until it is aligned with another discharge port 33. The internal material is then discharged through the other discharge port 33 to the second station to complete the bagging work. At this time, the second station enters the bag changing work. The switching drive unit 4 is started again, which causes the conveying pipe 32 to rotate to the first station. The bag changing work at the first station is completed when the bagging process is carried out at the second station. Repeating the above steps can realize the continuous switching of multiple stations, ensuring that the conveyor 1 can continuously convey materials without waiting for bag changing time or setting up intermediate material tanks.

[0060] During the rotation of the conveying pipe 32 inside the discharge hood 31, the discharge port abuts against the blocking surface 34 (i.e., it is located in the blocking position), so that the conveyor 1 continues to operate and the material conveyed to the discharge hood 31 is temporarily retained in the conveying pipe 32 until the conveying pipe 32 is rotated to the designated discharge port 33 (i.e., a designated discharge position).

[0061] Specifically, conveyor 1 can be a belt conveyor or a screw conveyor, etc. In this embodiment, a belt conveyor can be used. Its specific structure and working principle are existing technologies and will not be described in detail here.

[0062] Specifically, such as Figure 3 As shown, the switching drive component 4 includes a switching motor 41, a drive gear 42, and a driven gear 43 meshing with the drive gear 42. The switching motor 41 is mounted on the discharge hood 31, the drive gear 42 is rotatably mounted on the discharge hood 31, and the driven gear 43 is coaxially fixed on the conveying pipe 32. The output end of the switching motor 41 is coaxially connected to the drive gear 42 to drive the drive gear 42 to rotate, which in turn drives the driven gear 43 to rotate, thereby driving the conveying pipe 32 to rotate around the axis of the discharge hood 31.

[0063] Furthermore, a material gathering component is provided on the conveyor 1. The material gathering component includes two limiting plates 11 that are arranged opposite each other on both sides of the conveyor 1 and are inclined. The two limiting plates 11 are used to gather the granular material on the conveyor 1 and then let it enter the discharge hood 31.

[0064] like Figure 3-4As shown, the blocking surface 34 has multiple air holes 35 that connect the inner cavity of the discharge hood 31 to the outside. The discharge hood 31 is connected to a gas collecting hood 36, which is used to cover all the air holes 35. The inner cavity of the gas collecting hood 36 is connected to the air holes 35, and the gas collecting hood 36 is connected to a gas supply device.

[0065] When the conveying pipe 32 rotates to the blocking position, the gas generated by the gas supply device first passes through the gas collecting hood 36 and then through the air hole 35 into the conveying pipe 32 to disturb the material in the conveying pipe 32.

[0066] In this embodiment, an air hole 35 is provided to disturb the material temporarily retained in the conveying pipe 32. When the conveying pipe 32 rotates to the blocking position, the outlet of the conveying pipe 32 abuts against the blocking surface 34 to block the outlet of the conveying pipe 32, so that the material is temporarily retained in the conveying pipe 32. When the conveying pipe 32 has not rotated to the discharge position, the conveyor 1 is still in working state, and the material is continuously conveyed into the conveying pipe 32. At this time, the air supply device is activated, and the air supply device supplies gas into the gas collection hood 36. The gas entering the gas collection hood 36 is discharged through the air hole 35. The gas discharged from the air hole 35 can enter the conveying pipe 32 to disturb the material, avoid the material temporarily retained in the conveying pipe 32 from being compacted, blocked or caking, and at the same time reduce the friction between the material and the blocking surface 34.

[0067] It should be noted that the size of the pores 35 needs to be smaller than the diameter of a single particle of the particulate material, so that the material cannot enter, but the gas can pass through.

[0068] Specifically, the air supply device can be a fan or compressed air source, which can supply low-pressure, low-flow air to the air collection hood 36. The airflow is only used to loosen the material in the pipe and will not blow or splash the material. While ensuring the unblocking effect, it is necessary to avoid dust diffusion and material loss. The air supply device is not shown in the figure. The specific structure and working principle of the air supply device are existing technologies and will not be described in detail here.

[0069] like Figure 5-7 As shown, a blocking member 37 is connected to the outlet of the conveying pipe 32. The blocking member 37 is arranged in the same circumference as the blocking surface 34 and does not block the outlet of the conveying pipe 32. The blocking member 37 abuts against the blocking surface 34. When the conveying pipe 32 rotates to the blocking position, the blocking member 37 is suitable for blocking all the air holes 35 except for the air hole 35 corresponding to the position of the outlet of the conveying pipe 32.

[0070] In this embodiment, to enhance the disturbance effect of the gas discharged from the vent 35 on the material temporarily retained in the conveying pipe 32, a blocking member 37 is provided. When the conveying pipe 32 is rotated, the outlet of the conveying pipe 32 moves to the position where the vent 35 is provided. After the gas is discharged from the vent 35, it disturbs the material in the conveying pipe 32. At this time, the remaining vents 35 that are not aligned with the outlet of the conveying pipe 32 are blocked by the blocking member 37, so that the gas cannot be discharged through the vents 35. Under this setting, the gas is concentrated in the gas collection hood 36, and all the gas is concentrated on the material in the conveying pipe 32, which enhances the disturbance effect and improves the gas utilization rate. When the conveying pipe 32 rotates to the point where its outlet is aligned with the discharge port 33, the blocking member 37 blocks all the vents 35 to prevent gas loss. At this time, the gas supply device stops supplying gas.

[0071] Example 2: Figure 8 As shown, this embodiment further includes the following structure based on embodiment one: a material buffer component corresponding to the discharge port 33 is provided on the discharge hood 31, and the material buffer component includes:

[0072] Rotate the buffer cover 5 set on the discharge cover 31. The buffer cover 5 has an upper position and a lower position. When the buffer cover 5 is rotated to the lower position, the buffer cover 5 does not block the corresponding discharge port 33. When the buffer cover 5 is rotated to the upper position, the opening of the buffer cover 5 covers the corresponding discharge port 33.

[0073] A buffer drive component 6 is installed on the discharge cover 31. The buffer drive component 6 is connected to the buffer cover 5 to drive the buffer cover 5 to rotate.

[0074] In this embodiment, after the first station completes the bagging process, the switching drive component 4 is activated and drives the conveying pipe 32 to rotate to the second station. Simultaneously with the activation of the switching drive component 4, the buffer drive component 6 at the first station is activated and drives the buffer cover 5 at the first station to move from a lower position to an upper position, covering the discharge port 33 corresponding to the first station where bagging has been completed. This collects any excess material discharged, preventing material from scattering into the first station or into the bags at the first station before the conveying pipe 32 has fully rotated to contact the blocking surface 34 (i.e., the discharge port is not completely blocked), thus avoiding excessive weight deviation of the material in the bags. For example, after the conveying pipe 32 completes the bagging work at the second station, it returns to the first station under the drive of the switching drive component 4. At the same time as the switching drive component 4 starts, the buffer drive component 6 at the first station starts and drives the buffer cover bowl 5 located at the upper position to move to the lower position, so that all the material originally held in the buffer cover bowl 5 is first put into the packaging bag at the first station. After the conveying pipe 32 has completely moved to the first station, the conveying pipe 32 normally discharges the material into the packaging bag. The buffer cover bowl 5 first bags the buffered material, avoiding the problem of material accumulation at the discharge port 33 or material discharge delay during the transition stage when the conveying pipe 32 switches back to the first station.

[0075] Specifically, an electronic weighing component is installed at each bagging station. The packaging bags used to load materials are placed on the electronic weighing component. When the material enters the bag, the weight of the material in the bag is monitored in real time. When the weight of the material in the bag reaches a specified value, the electronic weighing component feeds the signal back to the controller, and the controller starts the switching drive component 4 and the buffer drive component 6.

[0076] Furthermore, the electronic weighing component may include a weighing platform and a weight sensor. The packaging bag for filling is placed on the weighing platform. The weight sensor collects the weight signal of the material in the bag in real time and transmits it to the controller. When the weight reaches the preset value, the controller synchronously starts the switching drive component 4 and the buffer drive component 6 to realize automatic station switching and material receiving. This part is not shown in the figure. The electronic weighing component is existing technology, and its specific structure and working principle will not be described in detail here.

[0077] Of course, other forms of electronic weighing components can also be used, as long as they can achieve the same effect.

[0078] Specifically, such as Figure 9 As shown, the buffer drive component 6 includes a cylinder 61, a rack 62, and a drive gear 63 meshing with the rack 62. A connecting plate is provided on the discharge cover 31, and a connecting rod is rotatably provided inside the connecting plate. One end of the connecting rod is coaxially connected to the drive gear 63. The buffer cover 5 is provided on the connecting rod. The cylinder 61 is connected to the discharge cover 31, and the telescopic end of the cylinder 61 is connected to the rack 62.

[0079] In this embodiment, when it is necessary to control the rotation of the buffer cover 5, the start cylinder 61 drives the rack 62 to move, and then drives the drive gear 63 to rotate through the meshing of the rack 62 and the drive gear 63, thereby realizing the rotation of the connecting rod and the buffer cover 5.

[0080] like Figure 10-11 As shown, a guide portion 51 is inclinedly provided inside the buffer cup 5, and the guide portion 51 gradually tilts downward from the direction away from the rotation center to the direction closer to the rotation center.

[0081] In this embodiment, to ensure that all the material contained inside the buffer bowl 5 is completely put into the packaging bag when it moves from the upper position to the lower position, a guide part 51 is provided. When the buffer bowl 5 moves from the lower position to the upper position, the excess material discharged enters the buffer bowl 5 and comes into contact with the guide part 51. With the inclined setting of the guide part 51, the material gathers at the lower point. When the buffer bowl 5 moves from the upper position to the lower position, the material originally located at the lower point moves to the higher point under the action of the guide part 51 and leaves the buffer bowl 5. The highest point of the buffer bowl 5 fits against the opening of the buffer bowl 5. With this setting, it can be ensured that all the material leaves the buffer bowl 5 along the inclined angle of the guide part 51 without any residue.

[0082] Furthermore, the size of the buffer bowl 5 should be larger than the size of the discharge port 33 to ensure that when the buffer bowl 5 moves from the lower position to the upper position, it can receive all the excess material discharged.

[0083] Example 3: Figure 14-15 As shown, this embodiment further includes the following structure based on embodiment one: the feeding component 2 includes:

[0084] A feeding hood 21 is connected to the conveyor 1. The feeding hood 21 has a feeding port at the top and a discharging port at the bottom.

[0085] At least one disturbance component is disposed within the feeding hood 21. The disturbance component includes a flexible component, which includes multiple sets of vertically spaced flexible buffer discs 22.

[0086] The feeding hood 21 is provided with a separate working area 23 and a blocking area 24. The flexible buffer disc 22 shuttles between the working area 23 and the blocking area 24 during rotation. The working area 23 is used to connect the feed inlet and the discharge outlet. The blocking area 24 is used to prevent the material on the flexible buffer disc 22 from entering the blocking area 24. When the material enters the working area 23 through the feed inlet and is discharged to the conveyor 1 through the discharge outlet, the material comes into contact with the flexible buffer disc 22. The flexible buffer disc 22 is suitable for reducing the impact force when the material falls.

[0087] The disturbance component also includes a rotary drive component 25, which is connected to a corresponding flexible component to drive multiple flexible buffer disks 22 in the flexible component to rotate, thereby causing different sections of the flexible buffer disks 22 in the circumferential direction to alternately shuttle between the working area 23 and the barrier area 24.

[0088] In this embodiment, the material falls into the working area 23 inside the feeding hood 21 through the feed inlet. During the falling process, it comes into contact with the flexible buffer disc 22. The flexible deformation of the flexible buffer disc 22 buffers and decelerates the material, reducing the impact of the material on the conveyor 1 and reducing particle breakage and dust. At the same time, the rotary drive component 25 drives the flexible buffer disc 22 to rotate continuously. When the flexible buffer disc 22 is driven to rotate, it can actively contact and disturb the material, slowing down the speed of the material falling freely and playing a buffering role. At the same time, the rotary drive component 25 can also make the flexible buffer disc 22 alternately shuttle between different parts of the circumference of the working area 23 and the barrier area 24, ensuring that the force on each part of the flexible buffer disc 22 is uniform and avoiding failure due to long-term local pressure.

[0089] Specifically, the rotary drive component 25 includes a rotary motor and a rotary shaft. The rotary motor is mounted on the feeding hood 21, and the rotary shaft is rotatably mounted on the feeding hood 21. The output end of the rotary motor is coaxially connected to the rotary shaft. Correspondingly, the flexible buffer discs 22 are sequentially mounted on the rotary shaft along the axial direction. When the rotary motor starts, it drives the rotary shaft, which in turn drives the flexible buffer discs 22 to rotate.

[0090] like Figure 15 As shown, two disturbance components are provided inside the feeding hood 21. The two disturbance components are arranged symmetrically. The flexible buffer disks 22 in the two disturbance components are staggered along the axial direction of the feeding hood 21. The flexible buffer disks 22 in the two disturbance components are configured to rotate in opposite directions under the action of the corresponding rotary drive component 25.

[0091] In this embodiment, the two sets of disturbance components are symmetrically arranged and the flexible buffer disks 22 are axially staggered, which can form a continuous buffer disturbance area; the two sets of flexible buffer disks 22 rotate in opposite directions, which can cause disturbances to the falling material in two different directions, loosening the slightly agglomerated material without squeezing and crushing the particles, and further improving the buffering and material dispersing effect.

[0092] Specifically, the reverse rotation of the two sets of flexible buffer disks 22 can be achieved by controlling the output shafts of their corresponding rotary motors to rotate in the opposite direction.

[0093] like Figure 16 As shown, the barrier region 24 is provided with a barrier member 26 corresponding to the flexible component, and the barrier member 26 is provided with a plurality of recovery chambers 27 corresponding to the flexible buffer plate 22.

[0094] In this embodiment, the barrier 26 separates the barrier area 24 from the material falling channel (i.e., the working area 23), and the recovery chamber 27 provided by it provides a dedicated reset space for the flexible buffer disk 22. When the flexible buffer disk 22, which is bent by the material, rotates into the recovery chamber 27, it can be released from the material pressure and fully rebound and reset by its own elasticity, ensuring that the flexible buffer disk 22 always has a stable buffering capacity and avoiding failure of the flexible buffer disk 22 under continuous feeding conditions.

[0095] Furthermore, the width of the recovery chamber 27 is slightly larger than the thickness of the flexible buffer disc 22, allowing the flexible buffer disc 22, which deforms under the impact of materials, to enter the recovery chamber 27 more effectively. Upon entering the recovery chamber 27, the chamber wall provides a degree of active correction, forcibly straightening the deformed flexible buffer disc 22. Simultaneously, as the flexible buffer disc 22 is screwed into the recovery chamber 27, the inlet edge of the recovery chamber 27 can scrape away and clean particles and dust adhering to the flexible buffer disc 22, preventing material from adhering and accumulating on it. This ensures that the flexible buffer disc 22 maintains a stable, clean, and non-tangling buffering effect during long-term use.

[0096] like Figure 16 As shown, the flexible buffer disk 22 includes a plurality of sector disks arranged circumferentially, and a disconnection channel 28 is provided between adjacent sector disks.

[0097] In this embodiment, the flexible buffer disk 22 adopts a non-closed ring structure and forms a disconnected channel 28 in the circumferential direction. On the one hand, it provides space for the bending deformation of the flexible buffer disk 22, avoids mutual squeezing and interference between the two ends in the circumferential direction, and ensures that the flexible buffer disk 22 rotates smoothly. On the other hand, it allows a small amount of accumulated material to fall smoothly through the disconnected channel 28, preventing the material from accumulating and getting stuck at the root of the flexible buffer disk 22, and further reducing the risk of the particles being squeezed and broken.

[0098] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
