Description

Technical Field

[0001] The present application relates to the technical field of drying equipment, and in particular to an intelligent zero-magnetic-increase belt-type plate dryer. Background Art

[0002] A vacuum belt dryer is a contact-type vacuum drying equipment with continuous feeding and continuous discharging. The liquid material to be dried directly enters the interior of the dryer under high vacuum through a conveying mechanism, and is spread on several drying belts inside the dryer. A special rubber roller driven by a motor drives the drying belt to move along the direction of the dryer cylinder at a set speed. Three mutually independent heating plates and a cooling plate are provided under each drying belt. The drying belt is closely attached to the heating plate and the cooling plate, and transfers the energy required for drying to the material in the form of contact heat transfer to dry the material.

[0003] Currently, when the conveying mechanism of the vacuum belt dryer is feeding, the material accumulates in the feeding box and enters the drying belt from the opening at the bottom of the feeding box. Since the feeding box is usually funnel-shaped and the material is relatively wet, after the material at the bottom of the feeding box leaks out, the materials above stick to each other and squeeze the inner wall of the feeding box, making it difficult for the material to fall normally, resulting in a bridging phenomenon of the material. It is necessary to manually knock and vibrate the material, which causes the material transportation to be discontinuous and further results in uneven material distribution.

[0004] Chinese Patent (202420512504.0) discloses a vacuum belt dryer, including a dryer main body. One end of the top of the dryer main body is fixedly installed with a material cylinder, the top of the material cylinder is movably installed with a cylinder cover, the top of the cylinder cover is fixedly installed with a feeding port, and it further includes a uniform feeding component arranged in the material cylinder to achieve uniform feeding of the material cylinder.

[0005] In view of the above related technologies, the inventor believes that although the above patent can prevent the material from accumulating in the material cylinder, the number of stirring rods is relatively large. Since the material is relatively wet, when the upper and lower adjacent stirring rods move, the material in the middle part will be squeezed, making the material closely attached, reducing the drying quality of the material. Therefore, it is necessary to find a method that can solve the bridging phenomenon of the material while avoiding affecting the drying of the material.

[0006] Therefore, there is still a defect that when the conveying mechanism is feeding, the material is prone to bridging, resulting in discontinuous material transportation and further uneven material distribution. Summary of the Invention

[0007] In order to solve the above technical problems, the present application provides an intelligent zero-magnetic-increase belt-type plate dryer.

[0008] An intelligent zero-magnetic-increased belt-type plate dryer provided by the present application adopts the following technical solutions: An intelligent zero-magnetic-increased belt-type plate dryer includes: A dryer main body; A blanking box, arranged at one end of the top of the dryer main body and communicating with the inside of the dryer main body; an annular groove is formed in the circumferential direction of the inner side wall of the blanking box; A driving assembly, arranged along the axial direction of the blanking box, and the power output end extends into the blanking box; A loosening assembly, sleeved on the power output end, and both ends roll in the annular groove respectively; Wherein, the driving assembly is used to drive the loosening assembly to roll in the annular groove; a plurality of groups of loosening plates are arranged circumferentially on the loosening assembly for stirring materials.

[0009] By adopting the above technical solutions, under normal conditions, materials are piled up in the blanking box. When feeding materials into the dryer main body, the materials at the bottom of the blanking box enter the dryer main body under the action of gravity. The materials above are in a wet state, and most of the materials stick together and also stick to the side wall of the blanking box, making it difficult for the materials to move down. At this time, start the driving assembly, and then drive the loosening assembly to rotate horizontally, playing a role in dispersing and stirring the materials, facilitating the downward sliding of the materials; since the loosening assembly rotates along with the power output end of the driving assembly and also rolls in the annular groove, the loosening plate rotates in the up and down direction, lifting the materials upward, playing a role in loosening the materials, avoiding the situation that the materials are still in a large-scale sticking state after falling, facilitating the materials to be laid flat in the dryer main body, and improving the drying efficiency and drying quality of the materials.

[0010] Preferably, the loosening assembly includes: A loosening rod, sleeved on the power output end; Two groups of gears, coaxially fixed at both ends of the loosening rod respectively; An annular rack, fixed in the annular groove; Wherein, both groups of the gears are meshed with the annular rack; a plurality of groups of the loosening plates are uniformly arranged along the circumferential direction of the loosening rod.

[0011] By adopting the above technical solutions, an annular gear is coaxially arranged in the annular groove, and gears are arranged on the loosening rod. Through the meshing of the gears with the annular rack, when the loosening rod rotates along with the driving assembly, power is provided for the loosening rod, enabling the loosening rod to rotate smoothly in the blanking box, avoiding the situation that the loosening rod cannot rotate normally due to local over-concentration of materials, and improving the load-bearing capacity of the materials in the blanking box and the loosening speed of the materials.

[0012] Preferably, the loosening assembly further includes: The annular seal has its top surface and bottom surface abutting against the upper and lower side walls of the annular groove respectively; both ends of the loosening rod penetrate through the annular seal.

[0013] By adopting the above technical solution, the annular seal can fully fit with the inner wall of the annular groove, fully isolate the gear and the annular rack from the space in the blanking box, prevent materials from entering the gear and the annular rack, and thus block the rotation of the gear, provide a smooth self-rotation environment for the loosening rod, and keep the materials continuously unclogged.

[0014] Preferably, the driving assembly includes: A motor, arranged on the top of the blanking box; A rotating shaft, coaxially connected to the power output end of the motor; the loosening assembly is sleeved on the rotating shaft.

[0015] By adopting the above technical solution, the loosening assembly is sleeved on the replaceable rotating shaft, and the length and width of the rotating shaft can be replaced according to the actual depth and width of the blanking box, so that the loosening assembly can meet the requirements of material unclogging in various environments.

[0016] Preferably, a sealing plate is slidably arranged horizontally at the bottom of the blanking box; the sealing plate has an elastic degree of freedom for horizontal sliding; the intelligent zero-magnetic incremental belt-type disk dryer further includes a delay assembly, and the delay assembly includes: A driving rod, vertically penetrating through the blanking box and having an elastic degree of freedom for vertical movement; the top of the driving rod has an arc-shaped contact surface and extends into the annular groove; the arc-shaped contact surface abuts against the loosening assembly; A pawl, one end of which is hinged to the bottom end of the driving rod; A driven rod, vertically slidably arranged on the blanking box; the bottom end of the driven rod penetrates through the sealing plate; Multiple groups of ratchet teeth, uniformly arranged along the axial direction of the driven rod; Wherein, the free end of the pawl is used for hooking the ratchet teeth.

[0017] By adopting the above technical solution, after the material is fed into the blanking box, the driving component is started to dredge the material in the blanking box; when the driving component starts to work, the material just fed into the blanking box is broken up by the loosening component. At this time, the amount of the broken-up material is small. If it is directly fed downward into the main body of the dryer, it will make the drying condition of this batch of material different from that of the material normally entering the main body of the dryer subsequently, which is likely to affect the quality of the product. After the bottom of the blanking box is sealed with a sealing plate, the initial small amount of material can be temporarily stacked at the bottom of the blanking box. After the material reaches a certain amount, the sealing plate is opened, and after the material at the bottom of the blanking box flows into the main body of the dryer, there is still enough material piled up at the bottom of the blanking box, ensuring the stable and continuous flow of the material into the main body of the dryer; by repeatedly squeezing the active rod with the loosening rod, and then repeatedly lifting the driven rod so that the driven rod disengages from the sealing plate, the sealing plate is far away from the blanking box under the action of elastic force, avoiding manual adjustment of the opening and closing state of the sealing plate and improving the precision of the equipment.

[0018] Preferably, a plurality of groups of mounting holes are uniformly formed along the axial direction of the driven rod; the delay component further includes: A mounting rod, one end of which is fixedly arranged on the ratchet tooth, and the other end is provided with a pin hole; the mounting rod penetrates through the mounting hole; A mounting pin, which is inserted into the pin hole.

[0019] By adopting the above technical solution, the ratchet tooth is prone to damage after long-term use. If there is a single damaged ratchet tooth and it is necessary to avoid replacing all the ratchet teeth, however, setting the ratchet tooth into a single replaceable structure greatly reduces the consumption of parts. By adopting the matching method of the mounting rod and the mounting hole, the replacement speed of the ratchet tooth is improved; using the mounting pin makes it more convenient to fix the mounting rod on the driven rod.

[0020] Preferably, the bottom of the blanking box is communicated with a cloth box; a rectangular discharge port is formed at the bottom of the cloth box; a cloth shaft is rotatably arranged in the cloth box; the cloth shaft is located directly below the blanking box; a plurality of receiving plates are uniformly distributed along the circumferential direction of the cloth shaft.

[0021] By adopting the above technical solution, after the material in the blanking box enters the cloth box downward, the cloth shaft drives the receiving plates to rotate, breaks up the material again, and uniformly lays the material into the main body of the dryer from the rectangular discharge port; keeping the material at a consistent drying degree and improving the drying quality of the material.

[0022] Preferably, a plurality of groups of conveyor belts arranged in a staggered manner in the vertical direction are arranged in the main body of the dryer; the conveyor belts are wound around the driving roller and the driven roller; the intelligent zero-magnetic enhanced belt type plate dryer further includes a recycling component, and the recycling component includes: A dust collecting bin, which is arranged in the main body of the dryer; A dust suction pipeline is arranged inside the dryer body; the dust suction pipeline has a plurality of air inlet ends, and the plurality of air inlet ends are respectively located on the front and back sides of the conveyor belt, and the air outlet end of the dust suction pipeline communicates with the dust collection bin; A dust outlet pipeline, one end of which communicates with the dust collection bin, and the other end is arranged above any one of the conveyor belts.

[0023] By adopting the above technical solution, when the materials on the conveyor belt fall, the dust generated during the falling of the materials being dried is sucked into the dust collection bin through the air inlet end of the dust suction pipeline, preventing the dust from adhering to the inside of the dryer body and reducing the cleaning difficulty of the dryer body in the later stage; after the dust in the dust collection bin is collected to a certain extent, it is mixed with the moisture sucked by the dust suction pipeline, re-accumulated into wet materials, and then the accumulated materials are re-sprayed onto any one of the conveyor belts through the dust outlet pipeline, reducing the loss during the drying process of the materials.

[0024] Preferably, the intelligent zero-magnetic-increasing belt-type plate dryer further includes a tensioning component, and the tensioning component includes: A load-bearing member, which has a load-bearing end and a free end; the load-bearing end of the load-bearing member abuts against the bottom of the dust collection bin, and the middle part of the load-bearing member is hinged to the dryer body; An elastic member, one end of which is connected to the load-bearing end of the load-bearing member, and the other end is connected to the bottom surface of the dryer body; A pulling rope, one end of which is connected to the free end of the load-bearing member; Wherein, any one of the driven rollers is slidably arranged along the length direction of the conveyor belt and is connected to the other end of the pulling rope; the pulling rope is used to provide a force for the driven roller to move away from the driving roller.

[0025] By adopting the above technical solution, the elastic member jacks up the load-bearing end of the load-bearing member upward, and the pulling rope pulls the driven roller away from the driving roller, thereby tightening the conveyor belt, improving the flatness of the conveyor belt surface, facilitating the uniform heating of the materials, and improving the drying efficiency of the materials; the dust collection bin is placed on the load-bearing end of the load-bearing member. When the dust in the dust collection bin is collected to a weight greater than the elastic force of the elastic member, the dust collection bin presses down the load-bearing member, causing the free end of the load-bearing member to move upward and reducing the pulling force of the pulling rope on the driven roller, making the conveyor belt stop, and creating a blank area without materials on the surface of the conveyor belt below it. The dust outlet pipeline evenly sprays the dust on the blank area, enabling the collected dust to be dried again. Compared with directly spraying the dust on the running conveyor belt, the drying quality of the materials is improved.

[0026] Preferably, the tensioning component further includes: A guide wheel, which is arranged inside the dryer body, and the pulling rope is lapped on the guide wheel.

[0027] By adopting the above technical solution, the guide pulley is used to guide the pulling rope, which facilitates the pulling rope to apply a pulling force to the driven roller and improves the working efficiency of the tensioning component.

[0028] In summary, the present application includes at least one of the following beneficial technical effects: 1. Under normal conditions, the materials are piled up in the feeding box. When feeding into the dryer main body, the materials at the bottom of the feeding box enter the dryer main body under the action of gravity. Since the materials above are in a wet state, most of the materials stick together and also stick to the side wall of the feeding box, making it difficult for the materials to move downward. At this time, the driving component is started, and then the loosening component is driven to rotate horizontally, which plays a role in dispersing and stirring the materials and facilitates the downward sliding of the materials. Since the loosening component rotates along with the power output end of the driving component and also rolls in the annular groove, the loosening plate rotates in the up and down direction, lifting the materials upward, playing a role in loosening the materials, avoiding the materials still being in a large-scale sticking state after falling, facilitating the materials to be laid flat in the dryer main body, and improving the drying efficiency and drying quality of the materials.

[0029] 2. After the materials are fed into the feeding box, the driving component is started to dredge the materials in the feeding box. When the driving component starts to work, the materials just fed into the feeding box are scattered by the loosening component. At this time, the amount of the scattered materials is small. After directly feeding them into the dryer main body, the drying situation of this batch of materials will be different from that of the materials normally entering the dryer main body later, which is likely to affect the product quality. After the bottom of the feeding box is closed with a sealing plate, the initial small amount of materials can be temporarily stacked at the bottom of the feeding box. After the materials reach a certain amount, the sealing plate is opened, and after the materials at the bottom of the feeding box flow into the dryer main body, there are still enough materials piled up at the bottom of the feeding box to ensure the stable and continuous flow of the materials into the dryer main body. By the loose rod squeezing the active rod multiple times, and then lifting the driven rod multiple times so that the driven rod disengages from the sealing plate, the sealing plate is separated from the feeding box under the action of elastic force, avoiding manual adjustment of the opening and closing state of the sealing plate and improving the precision of the equipment.

[0046] Refer to Figure 3 and Figure 4 , a sealing plate 22 is slidably arranged horizontally at the bottom of the blanking box 2, and a limiting hole 222 is vertically formed in the sealing plate 22; specifically, first limiting plates 221 are arranged on both sides of the sealing plate 22, a first support plate 64 is arranged on the blanking box 2 or the cloth feeding box 6, and first springs 2211 are respectively connected between the first support plate 64 and the two first limiting plates 221, and the first springs 2211 provide a force for the limiting plates to move away from the blanking box 2.

[0047] The delay component 5 includes a driving rod 51, a ratchet pawl 52, a driven rod 53, a plurality of groups of ratchet teeth 54, a mounting rod 55 and a mounting pin 56; the driving rod 51 is vertically arranged on the blanking box 2, and a second limiting plate 511 is arranged on the driving rod 51; a second support plate 23 is arranged on the blanking box 2, the second limiting plate 511 is directly above the second support plate 23, the driving rod 51 penetrates through the second support plate 23, and a second spring 512 is sleeved on the driving rod 51, and the second spring 512 is located between the second limiting plate 511 and the second support plate 23; the top of the driving rod 51 has an arc-shaped contact surface and extends into the annular groove 21; the arc-shaped contact surface at the top of the driving rod 51 abuts against the loosening component 3.

[0048] The follower rod 53 is slidably arranged vertically on the blanking box 2; the bottom end of the follower rod 53 penetrates through the sealing plate 22; specifically, the follower rod 53 is located below the second support plate 23; after the sealing plate 22 is closed, the follower rod 53 slides into the limiting hole 222 of the sealing plate 22 under the action of gravity; multiple groups of ratchet teeth 54 are uniformly arranged along the axial direction of the follower rod 53.

[0049] Refer to Figure 4 and Figure 5 , one end of the pawl 52 is hinged to the bottom end of the driving rod 51; the other end of the pawl 52 is a free end, and the free end of the pawl 52 has an arc-shaped end face 521 and a limiting plane 522, and the arc-shaped end face 521 is located outside the limiting plane 522; the upper end face of the ratchet tooth 54 is an arc-shaped guiding end face, and the lower end face is a plane; when the pawl 52 moves downward, the arc-shaped end face 521 of the pawl 52 abuts against the upper end face of the ratchet tooth 54 and pushes the pawl 52 to rotate away from the blanking box 2; when the pawl 52 moves downward to the bottommost position, the pawl 52 rotates back, and the limiting plane 522 of the pawl 52 fits with the lower end face of the ratchet tooth 54; then the pawl 52 moves upward and pulls and drives the follower rod 53 to move upward.

[0050] Refer to Figure 6 , a plurality of groups of mounting holes 531 are uniformly opened along the axial direction of the follower rod 53, and the delay assembly 5 further includes a mounting rod 55 and a mounting pin 56; one end of the mounting rod 55 is fixedly arranged on the ratchet tooth 54, and the other end is provided with a pin hole; the mounting pin 56 is inserted into the pin hole; when installing the ratchet tooth 54, only need to insert the mounting rod 55 into the mounting hole 531 and insert the mounting pin 56 into the pin hole; so that the ratchet tooth 54 is convenient to replace.

[0051] Refer to Figure 7 , the bottom of the blanking box 2 is communicated with a cloth box 6; a rectangular discharge port 61 is opened at the bottom of the cloth box 6; a cloth shaft 62 is rotatably arranged in the cloth box 6; the cloth shaft 62 is located directly below the blanking box 2; a plurality of receiving plates 63 are uniformly distributed along the circumferential direction of the cloth shaft 62.

[0052] Specifically, the axial direction of the cloth shaft 62 is parallel to the length direction of the rectangular discharge port 61; after the material in the blanking box 2 enters the cloth box 6 downward, the cloth shaft 62 drives the receiving plate 63 to rotate, disperses the material again, and uniformly lays the material into the dryer main body 1 from the rectangular discharge port 61; a driving motor 41 can also be installed on the side wall of the cloth box 6, and the cloth shaft 62 is coaxially connected with the power output shaft of the driving motor 41; the driving motor 41 is not shown in the figure.

[0053] Refer to Figure 8 , Figure 9 and Figure 10, A plurality of groups of conveyor belts 11 are arranged vertically in sequence within the dryer main body 1, and the plurality of groups of conveyor belts 11 are arranged staggeredly in the front-back direction. Each group of conveyor belts 11 is respectively wound around a driving roller and a driven roller 12; The recovery assembly 7 includes a dust collection bin 71, a dust suction pipeline 72, and a dust outlet pipeline 73; The dust collection bin 71 is arranged within the dryer main body 1. The intake ends of the dust suction pipeline 72 are respectively arranged on the front and rear sides of the conveyor belt 11, and the outlet end of the dust suction pipeline 72 is communicated with the dust collection bin 71; One end of the dust outlet pipeline 73 is communicated with the dust collection bin 71, and the other end is arranged above any conveyor belt 11 that is not at the top.

[0054] Specifically, the conveyor belt 11 is made of PTFE material; The intake end of the dust suction pipeline 72 is arranged between two adjacent conveyor belts 11 up and down. A dust suction fan is installed at the intake end of the dust suction pipeline 72 to suck the dust splashed when the material falls during drying; The dust is sucked into the dust collection bin 71; A pressure pump is installed at the end where the dust outlet pipeline 73 is communicated with the dust collection bin 71 to suck out the dust in the dust collection bin 71 and sprinkle it onto the conveyor belt 11 for secondary drying; To prevent the drawing from being disordered, the dust suction fan and the pressure pump are not shown.

[0055] It should be noted that the side of the conveyor belt 11 close to the feeding bin is defined as the front side of the conveyor belt 11, and the side of the conveyor belt 11 far from the feeding bin is defined as the rear side of the conveyor belt 11; Except for the driven roller 12 at the topmost, any other driven roller 12 can be slidably arranged on the dryer main body 1 along the length direction of the conveyor belt.

[0056] Refer to Figure 9 , The tensioning assembly 8 includes a load-bearing member 81, an elastic member 82, a pull rope 83, and a guide pulley 84; The load-bearing member 81 has a load-bearing end and a free end; The load-bearing end of the load-bearing member 81 abuts against the bottom of the dust collection bin 71, and the middle of the load-bearing member 81 is hinged to the dryer main body 1; The free end of the load-bearing member 81 is connected to one end of the pull rope 83, and the other end of the pull rope 83 is connected to the slidably arranged driven roller 12; The elastic member 82 is a spring; One end of the elastic member 82 is connected to the load-bearing end of the load-bearing member 81, and the other end is connected to the bottom surface of the dryer main body 1; The guide pulley 84 is arranged directly in front of the slidably arranged driven roller 12 to direct the force of the pull rope 83 pulling the slidably arranged driven roller 12 into a horizontal force, reducing the burden on the load-bearing member 81.

[0057] Under normal conditions, the elastic member 82 pushes up the load-bearing end of the load-bearing member 81. The free end of the load-bearing member 81 moves downward, and the driven roller 12 is pulled away from the driving roller through the pull rope 83, playing a role in tensioning the conveyor belt. When the dust in the dust collection bin 71 is collected to a weight greater than the elastic force of the elastic member 82, the dust collection bin 71 presses down the load-bearing end of the load-bearing member 81, causing the free end of the load-bearing member 81 to move upward, reducing the force of the pull rope 83 on the sliding conveyor roller, and thus losing the function of tensioning the conveyor belt 11. As a result, the conveyor belt 11 stops or slows down. At this time, a blank area without materials appears on the surface of the conveyor belt 11 below this conveyor belt 11. The dust outlet pipe 73 evenly sprays the dust on the blank area, enabling the collected dust to be dried again. As the weight of the dust collection bin 71 decreases, the elastic member 82 pushes up the load-bearing end of the load-bearing member 81 until it resets, causing the conveyor belt 11 to be tensioned again and move.

[0058] When the guide wheel 84 is not provided, it is necessary to ensure that the load-bearing member 81 is located in front of the conveyor belt. After the guide wheel 84 is set, the position of the load-bearing member 81 can be set at any position, as long as it is ensured that the pull rope 83 pulls the sliding driven roller 12 forward.

[0059] It should be noted that when the conveyor belt 11 stops or slows down, the sealing plate 22 needs to be reset to stop the material from entering the dryer main body 1 to avoid the material from accumulating on the conveyor belt. Both the dust suction pipe 72 and the dust outlet pipe 73 are made of flexible materials to prevent the dust suction pipe 72 and the dust outlet pipe 73 from being pulled and damaged when the dust collection bin 71 moves downward.

[0060] Refer to Figure 10 、 Figure 11 and Figure 12 The load-bearing member 81 has a V-shaped structure with an obtuse angle. To improve the stability of the dust collection bin 71, a bearing plate 85 is added between the load-bearing end of the load-bearing member 81 and the dust collection bin 71. The load-bearing end of the load-bearing member 81 is hinged to the bottom of the bearing plate 85. Multiple sets of tensioning and loosening components 8 can be set. The load-bearing ends of the load-bearing members 81 of each set of tensioning and loosening components 8 are hinged to the bottom of the bearing plate 85 to improve the stability of the bearing plate 85. The elastic member 82 is arranged between the bearing plate 85 and the bottom surface of the dryer main body 1. Since the middle of the load-bearing member 81 is hinged to the bottom surface of the dryer main body 1, when the dust collection bin 71 drops, the position will shift. To solve the above problem, a slider 13 is slidably arranged on the bottom surface of the dryer main body 1 along the length direction of the conveyor belt 11, and the middle of the load-bearing member 81 is hinged to the slider 13.

[0061] When the weight of the material in the dust collection bin 71 is greater than the elastic force of the elastic member 82, the dust collection bin 71 presses down the elastic member 82 and pushes the slider 13 in the direction of the conveyor belt, ensuring that the dust collection bin 71 moves vertically downward and improving the stability of the dust collection bin 71.

[0062] The working principle of an intelligent zero-magnetic-increasing belt-type plate dryer in this application is as follows: After the material enters from the top of the feeding box 2, the motor 41 drives the rotating shaft 42 to rotate, which drives the loosening rod 31 to rotate. At the same time, the gears 32 at both ends of the loosening rod 31 mesh with the annular gear 32, causing the loosening rod 31 to rotate relative to the rotating shaft 42. While the loosening rod 31 stirs the material horizontally, the loosening plate 34 pushes the material upward to make it rise.

[0063] When the material first enters the feeding box 2, the sealing plate 22 is in a closed state. After the loosening rod 31 rotates and squeezes the active rod 51 to move downward, the pawl 52 flips outward under the extrusion of the top surface of the ratchet tooth 54. After the active rod 51 moves downward to the limit, the pawl 52 resets and hooks the bottom surface of the ratchet tooth 54. After the loosening rod 31 moves away from the top end of the active rod 51, the active rod 51 resets under the push of the second spring 512, and the pawl 52 pulls the ratchet tooth 54 upward and drives the driven rod 53 to move upward, causing the driven rod 53 to move away from the sealing plate 22. Repeat the above operations until the driven rod 53 completely disengages from the sealing plate 22, and then the sealing plate 22 moves away from the feeding box 2 under the action of the first spring 2211, allowing the material to enter the cloth box 6 from the bottom of the feeding box 2.

[0064] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application accordingly, therefore: All equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
