Description

Technical Field

[0001] This invention relates to the field of carding machinery technology, specifically to a carding feeder. Background Technology

[0002] Currently, timber raw materials, bamboo poles, and cylindrical lightweight materials are loaded onto trucks using log grabbers and transported by dump trucks. During unloading, the timber raw materials are often piled up haphazardly, creating a chaotic situation. This causes significant inconvenience for secondary processing, requiring manual rearrangement before being moved to another factory area for processing. This manual stacking method is incompatible with existing conveyor and processing production lines, resulting in low automation. This manual operation is primitive, inefficient, and wastes considerable time, manpower, and resources, increasing labor costs and hindering production speed. Furthermore, the handling process poses significant safety hazards, with the risk of injury to operators from falling debris. Summary of the Invention

[0003] The purpose of this invention is to provide a combing and feeding machine that can improve the production efficiency of combing wood raw materials, reduce production costs, and ensure safe operation.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a carding and feeding machine, comprising a frame, a feeding assembly, a carding assembly, a belt conveyor, and a power unit; a storage hopper is installed on the frame; the feeding assembly includes a feeding roller and multiple material-pushing curved plates evenly distributed on the feeding roller; both ends of the feeding roller are respectively mounted on the upper front side of the frame via first bearing seat assemblies; the carding assembly includes a carding roller and multiple rows of carding teeth evenly distributed on the carding roller; both ends of the carding roller are respectively mounted on the middle of the frame and located at the bottom of the storage hopper via second bearing seat assemblies; a feeding connecting plate is also provided between the feeding roller assembly and the carding roller assembly; the feeding connecting plate is inclined and fixedly installed on the frame; the belt conveyor is installed at the lower part of the frame and located below the carding assembly; the power unit is installed on the frame and can drive the feeding roller and the carding roller to rotate.

[0005] Furthermore, the feeding connecting plate includes a feeding straight plate and a discharging curved plate.

[0006] Furthermore, the angle formed by the line connecting the centers of the feeding roller and the combing roller and the feeding straight plate is 0°-5°, and the vertical distance between the tail of the feeding straight plate and the plane passing through the centers of the two rollers is L / 4-L / 2, where L is the distance between the lines connecting the centers of the two rollers.

[0007] Furthermore, the feeding roller includes a first roller, a first flange fixedly installed at both ends of the first roller, and a first rotating shaft connected to the first flange. The first rotating shaft is installed on the first bearing seat assembly, and multiple material-pushing bending plates are evenly distributed on the roller, with the included angle of the material-pushing bending plates being 140°-160°.

[0008] Furthermore, the combing roller includes a second roller, a second flange fixedly installed at both ends of the second roller, and a rotating shaft connected to the second flange. The rotating shaft is installed on the second bearing seat assembly, and multiple rows of combing teeth are evenly distributed on the roller.

[0009] Furthermore, the conveyor includes a drive roller, a frame, a conveyor belt, an adjusting bracket, a driven roller, and multiple support rollers evenly distributed on the frame. The drive roller is installed on one side of the frame, and the driven roller is installed on the other side of the frame via the adjusting bracket. The conveyor belt is fitted onto the drive roller and the driven roller.

[0010] Furthermore, the power unit includes a motor and a gearbox connected to the motor. The output shaft of the gearbox is connected to one end of the feeding roller via a cross-slider coupling. A first transmission wheel and a second transmission wheel are respectively connected to the same end of the feeding roller and the combing roller. The first transmission wheel and the second transmission wheel are connected to each other via a transmission assembly.

[0011] Furthermore, the transmission assembly includes a rotating shaft mounted on a frame via two bearing seats, on which a first driven wheel and a second driven wheel are mounted. The first driven wheel and the first transmission wheel, and the second driven wheel and the second transmission wheel are respectively connected by a chain or a belt.

[0012] Furthermore, the transmission assembly also includes a protective cover.

[0013] Furthermore, a protective cover for the power unit is also installed on the frame.

[0014] The beneficial effects of this invention are: compact structure, high efficiency, convenience, and speed, effectively reducing the labor intensity of workers. Specifically, a power unit drives a combing roller mounted on the frame to rotate, which can comb messy materials neatly and remove impurities from the material's outer surface through the combing teeth. As the combing roller rotates, the combing teeth push the material upwards, one by one, onto the feeding receiving plate, and finally onto the feeding roller's feeding bending plate. Each feeding bending plate carries one piece of wood raw material, and with rotation, the wood raw material is quantitatively conveyed out of the frame to a designated position. Then, the operator continuously adds the material to be combed into the storage hopper using a loader, forming a circular production line. This invention can be integrated with subsequent processing production lines to improve the automation level of material processing.

[0015] This invention can be used to neatly comb raw materials of different diameters and lengths and to feed them quantitatively and steadily. The raw materials processed can be long strips of wood, bamboo, square tubes, oval tubes, steel pipes, iron shafts, etc., and the shapes can be round, oval, square, etc. Attached Figure Description

[0034] like Figure 1-2 As shown, the present invention provides a carding and feeding machine, which includes a frame 10, a feeding assembly 20, a carding assembly 30, a belt conveyor 50, and a power unit 60.

[0035] Among them, such as Figure 3 As shown, the frame 10 includes a main frame 15 and a power unit mounting frame 13. A storage hopper is mounted on the frame 10, comprising a rear inclined side plate 12 and left and right inclined side plates 14. The storage hopper is installed on the rear side of the main frame 15, forming a storage space with the feeding connection plate 11 for placing the wood raw materials to be combed. The feeding plate 11 and the bottom of the rear side plate 12 have corresponding notches for the combing teeth 39 to pass through. The feeding assembly 20, combing assembly 30, and belt conveyor 50 are respectively mounted on the main frame 15; the power unit 60 is fixedly connected to the power unit mounting frame 13.

[0036] In practical applications, the storage hopper can be set in terms of volume, length, width and height according to actual needs. For example, the storage hopper can be designed to have a large capacity, which can hold about 1.5 tons of wood raw materials at one time. The length of a single piece of wood raw material is between 1 and 2.5 meters. After being intertwined, the length of a bundle is about 4 meters.

[0037] like Figure 4-5 As shown, the combing assembly 30 includes a combing roller and three rows of combing teeth 39 evenly distributed on the combing roller. Multiple combing teeth 39 in each row are spaced apart. The teeth of the combing teeth 39 have a certain arc shape. When rotating, they can move the wood raw material in the storage hopper, thereby combing and straightening it. They can also push the wood raw material upwards and peel off the bark and other impurities from the surface of the wood raw material, thus having a dual function. The two ends of the combing roller are respectively mounted in the middle of the frame 10 and located at the bottom of the storage hopper 10 via second bearing seat assemblies. A feeding connecting plate 11 is also provided between the feeding roller assembly 20 and the combing roller assembly 30. The feeding connecting plate 11 is inclined and fixedly mounted on the frame 10. A belt conveyor 50 is installed at the lower part of the frame 10 and below the combing assembly 30. A power unit 60 is installed on the frame 10 and can drive the feeding roller and the combing roller to rotate.

[0038] Specifically, the carding roller includes a second roller 38, second flanges 36 fixedly installed at both ends of the second roller 38, and a rotating shaft 32. The rotating shaft 32 is mounted on the second bearing housing assembly, and one end of the second rotating shaft 32 is fixedly connected to the second flange 36 by a first nut 37. Multiple rows of carding teeth 39 are evenly distributed on the roller 28. The second bearing housing assembly consists of a second bearing housing 33, a second bearing 34, and a second bearing cover 35.

[0039] like Figure 6-8 As shown, the feeding assembly 20 includes a feeding roller and six material-pushing curved plates 29 evenly distributed on the feeding roller. The material-pushing curved plates 29 are obtuse-angled, which can stably support the wood raw materials and prevent the wood raw materials from slipping out during the conveying process. The two ends of the feeding roller are respectively mounted on the upper front side of the frame 10 through the first bearing seat assembly.

[0040] The feeding roller includes a first roller 28, a first flange 26 fixedly installed at both ends of the first roller 28, and a first rotating shaft 22. The first rotating shaft 22 is mounted on the first bearing housing assembly, and one end of the first rotating shaft 22 is fixedly connected to the first flange 26 by a first nut 27. Multiple material-pushing bending plates 29 are evenly distributed on the roller 28, and the included angle α of the material-pushing bending plates is 140°-160°. The first bearing housing assembly consists of a first bearing housing 23, a first bearing 24, and a first bearing cover 25.

[0041] The aforementioned feeding connecting plate 11 includes a feeding straight plate 111 and a discharging arc-shaped plate 112. The angle β formed by the line connecting the centers of the feeding roller and the combing roller and the feeding straight plate is 0°-5°. The vertical distance C between the tail of the feeding straight plate and the plane passing through the centers of the two rollers is L / 4-L / 2, where L is the distance between the lines connecting the centers of the two rollers. There is a certain height difference between the combing roller and the feeding roller, transitioned by the feeding straight plate. The combing roller pushes the wood raw material upwards, moving it along the feeding straight plate until it reaches the top, where it falls one by one onto the feeding roller's guide plate 29. As the feeding roller rotates, the wood raw material is fed out, achieving quantitative conveying. The discharging arc-shaped plate is set along the outer circumference of the feeding assembly 20, and its arc-shaped plate space corresponds to the space formed between the two guide plates. In this way, it can be ensured that the wood raw material does not leak out during the conveying process, achieving automated quantitative and stable conveying.

[0042] like Figure 9 , 10As shown, the conveyor 50 includes a drive roller 51, a frame 52, a conveyor belt 53, an adjusting bracket 54, a driven roller 55, and multiple support rollers 56 evenly distributed on the frame 52. The drive roller 51 is mounted on one side of the frame 52, and the driven roller 55 is mounted on the other side of the frame via the adjusting bracket 54. The conveyor belt 53 is fitted onto the drive roller 51 and the driven roller 55. By setting up the conveyor 50, the bark and other debris stripped from the combing roller 30 can be conveyed to the bottom.

[0043] like Figure 11 , 12 As shown, the power unit 60 includes a motor 61 and a reduction gearbox 65 connected to the motor. The output shaft of the reduction gearbox 65 is connected to one end of the feeding roller 28 via a cross-slider coupling 66. A first transmission wheel 21 and a second transmission wheel 31 are respectively connected to the same end of the feeding roller 28 and the combing roller 38. The first transmission wheel 21 and the second transmission wheel 31 are connected via a transmission assembly 40.

[0044] like Figure 13 , 14 As shown, the transmission assembly 40 includes a rotating shaft 45 mounted on the frame 10 via two bearing seats 46. A first driven wheel 43 and a second driven wheel 44 are mounted on the rotating shaft 45. The first driven wheel 43 is connected to the first transmission wheel 21 via a first chain 42; the second driven wheel 44 is connected to the second transmission wheel 31 via a second chain 47. Of course, in practical applications, a belt can be used instead of a chain to achieve the same effect. In addition, depending on the power requirements, a torque overload protection coupling can be added after the second driven wheel 44. When the torque causing the wood material to jam is too large, overload protection can be provided to prevent damage to the rollers, burning of bearings, and bending of the shaft.

[0045] In addition, such as Figure 15 As shown, a protective cover 70 for the power unit 60 is also installed on the frame. By setting the protective cover 41 and the protective cover 70, safety can be ensured and damage to the equipment caused by collision can be prevented.

[0046] The working process of this invention is as follows: It can be used with regularly shaped materials (such as wood, bamboo, and lightweight cylindrical materials), for example, when working with wood materials, and can be used in conjunction with the conveyor line of a wood processing production line. The conveyor line is set at the outlet end of the combing and feeding machine. During production, a log loader feeds wood materials of different lengths and irregular shapes or other materials into the hopper (such as...). Figure 16 , 17(As shown). When the combing and feeding machine is started, the power unit 60 drives the combing assembly 30 mounted on the frame to rotate via a cross-slider coupling. This combs the wood material in the hopper, simultaneously removing debris from the outer layer, which falls onto the conveyor 50 located at the bottom of the frame and is then transported to another location. The combed wood material is then conveyed through the combing teeth to the feeding connecting plate 11 mounted on the frame 10, and then from the feeding connecting plate 11 to the feeding roller's guide plate 39 mounted on the frame. As the feeding roller rotates, the wood material is quantitatively conveyed out of the frame and onto the wood conveyor line, then transported to a designated location, forming a cyclical automated production line.

[0047] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
