[0029] As shown in Figure 1 A paperboard friction feeding machine, comprising a conveying mechanism 1 and a distributing mechanism 2, for automatic single feeding of paperboard, the conveying mechanism 1 comprises a fixed part 11, a conveying part 12 and a driving part 13, the driving part 13 drives the conveying part 12 to rotate relative to the fixed part 11, and the top of the conveying part 12 is configured as a conveying plane 14 to carry and convey paperboard. The fixed part 11 is fixedly provided with a support beam 31, the support beam 31 is parallel to the conveying plane 14, and the support beam 31 is perpendicular to the moving direction of the conveying part 12, the support beam 31 is located at the top of the conveying part 12 and maintains a distance from the conveying part 12, so that the paperboard can pass smoothly. The distributing mechanism 2 is adjustably connected to the support beam 31 in a direction perpendicular to the conveying plane 14, and the number of paperboards passing through is controlled by adjusting the distance between the end of the distributing mechanism 2 and the conveying plane 14.

[0030] It is worth noting that the adjustable connection refers to a connection mode capable of changing the relative position between two or more components, and in the present embodiment, the adjustable connection allows the distributing mechanism 2 to move up and down relative to the support beam 31 in a direction perpendicular to the conveying plane 14.

[0031] The drive unit 13 includes a power motor 131 and a speed regulator 132. The power motor 131 is connected to the speed regulator 132 in a transmission connection. The speed regulator 132 is connected to the conveying unit 12 in a transmission connection via a transmission shaft 133. The power motor 131 drives the conveying unit 12 in a transmission connection. The speed regulator 132 adjusts the speed of the power motor 131. Preferably, the speed regulator 132 is a reduction gear set.

[0032] like Figure 2 As shown, the material distribution mechanism 2 includes a sliding member 21 and an adjusting member 22. In this embodiment, the conveying plane 14 is horizontal, and the sliding member 21 slides vertically relative to the support beam 31. That is, the end of the sliding member 21 is close to or away from the conveying plane 14, adjusting the distance between the sliding member 21 and the conveying plane 14. The adjusting member 22 passes through the sliding member 21 and the support beam 31 in sequence. Specifically, the sliding member 21 is "L"-shaped, so that the sliding member 21 and the support beam 31 overlap in the vertical direction. The adjusting member 22 is movably inserted into the sliding member 21 in the vertical direction, and the adjusting member 22 is threadedly connected to the support beam 31 in the vertical direction. The adjusting member 22 is fitted with a return spring 23, which is arranged in the vertical direction. One end of the return spring 23 abuts against the sliding member 21, and the other end abuts against the support beam 31. Preferably, the adjusting member 22 is fixedly provided with a knob for adjustment by the operator.

[0033] Before the cardboard is loaded, the operator rotates the adjusting component 22. When the adjusting component 22 is screwed toward the support beam 31, the sliding component 21 moves toward the direction closer to the conveying part 12 to reduce the distance between the sliding component 21 and the conveying part 12, so as to pass through the thin wallpaper. During this process, the return spring 23 is compressed, and the elastic potential energy of the return spring 23 increases. When the adjusting component 22 is disengaged from the support beam 31, the sliding component 21 moves toward the direction away from the conveying part 12. During this process, the return spring 23 releases its elastic potential energy, causing the sliding component 21 to rise, so as to increase the distance between the sliding component 21 and the conveying part 12, so as to pass through the thick wallpaper, or to facilitate the operator to perform maintenance on the equipment.

[0034] A support rod 32 is fixedly mounted on the support beam 31. The support rod 32 is parallel to the conveying section 12, and its bottom surface is parallel to the conveying plane 14. In this embodiment, the length direction of the support rod 32 is consistent with the conveying direction of the conveying section 12. The support rod 32 is rotatably connected to several rollers 33, which are distributed along the length direction of the support rod 32, i.e., along the conveying direction of the conveying section 12. The rollers 33 and the support rod 32 are rotatably connected via a connecting rod 34. Specifically, the connecting rod 34 is rotatably connected to the support rod 32 and rotatably connected to the rotation center of the rollers 33. The connecting rod 34 and the support rod 32 are inclined, i.e., the central axis of the connecting rod 34 is at an angle to the conveying plane 14. Under the action of the rollers 33's own weight, the rollers 33 adaptively abut against the surface of the cardboard through the connecting rod 34, making the cardboard fit against the conveying section 12, reducing the risk of relative slippage between the cardboard and the conveying section 12, and improving conveying efficiency and accuracy. In other embodiments, the length direction of the support rod 32 is perpendicular to the conveying direction of the conveying section 12, and a plurality of rollers 33 are distributed along the conveying direction perpendicular to the conveying section 12.

[0035] Preferably, the connecting rod 34 is provided with a tension spring 35. One end of the tension spring 35 is fixed to the connecting rod 34, and the other end is fixed to the support rod 32 by a screw. The connection point between the tension spring 35 and the connecting rod 34 is located at the connection point of the support rod 32 away from the rotation connection point of the roller 33. That is, the connection point of the tension spring 35, the rotation connection point of the support rod 32, and the rotation connection point of the roller 33 are arranged sequentially along the length direction of the connecting rod 34.

[0036] like Figures 1 to 3 As shown, the fixing part 11 includes a frame 111 and a plurality of conveyor frames 112, each of which is fixed to the frame 111 by a plurality of bearing shafts 113. Specifically, both ends of the bearing shafts 113 are fixedly connected to the frame 111, the plurality of bearing shafts 113 are parallel to the same horizontal plane, and the plurality of bearing shafts 113 are perpendicular to the conveying direction of the conveying part 12. The conveyor frames 112 are movably inserted into the plurality of bearing shafts 113, and the plurality of conveyor frames 112 are all along the conveying direction of the conveying part 12, with adjacent two conveyor frames 112 being parallel to each other.

[0037] Specifically, in this embodiment, there are five conveyor racks 112, and the spacing between adjacent conveyor racks 112 is the same, so as to provide uniform support for the cardboard. In other embodiments, the number of conveyor racks can be determined according to the specific shape or size of the cardboard.

[0038] The fixing part 11 is provided with two baffles 15, which are parallel to the conveying direction of the conveying part 12. The two baffles 15 are fixed on the frame 111 on both sides of the conveying part 12 to limit the paperboard and ensure that the paperboard moves along the conveying direction.

[0039] The first locking bolt 114 is arranged on each conveying frame 112 to adjust the tension between the conveying frame 112 and the bearing shaft 113. Specifically, the conveying frame 112 is provided with a threaded hole that is open towards the bearing shaft 113, and the first locking bolt 114 is threadedly connected to the conveying frame 112 through the threaded hole. When the first locking bolt 114 is tightly connected to the bearing shaft 113, the conveying frame 112 is locked with the bearing shaft 113, and when the first locking bolt 114 is disconnected from the bearing shaft 113, the conveying frame 112 slides relative to the bearing shaft 113 to adjust the distance between adjacent conveying frames 112.

[0040] The conveying part 12 includes a plurality of conveying belts 121 and a plurality of conveying wheels. The conveying belts 121 are one-to-one rotationally connected, and the conveying wheels are rotationally connected in the conveying frame 112. Specifically, two conveying wheels are arranged in the conveying frame 112, one of which is fixedly connected to the transmission shaft 133 as a power output, and the other is a driven wheel. The driving member 13 drives the plurality of conveying belts 121 to rotate synchronously through the transmission shaft 133. The conveying belts 121 are arranged around the conveying wheels to convey the paperboard. The upper end surfaces of the plurality of conveying belts 121 form a conveying plane 14, and the driving member 13 drives the plurality of conveying belts 121 to rotate synchronously through the transmission shaft 133.

[0041] The plurality of conveying frames 112 and the plurality of conveying belts 121 form a plurality of split conveying structures. Compared with a single conveying structure, the split conveying structure has flexibility and expandability. The plurality of split conveying structures can be flexibly configured according to the specific needs of paperboard conveying. They can operate independently or cooperatively, providing more possibilities for paperboard conveying. As the amount of paperboard conveying increases or decreases, the number of split conveying structures can be easily increased or decreased to adapt to changes in production requirements. This scalability makes the split conveying structure more flexible in dealing with different sizes of paperboard conveying tasks.

[0042] As shown in FIG. 1, Figure 4 The fixed part 11 is fixedly provided with a load beam 41, which is located at the conveying end of the conveying part 12. The load beam 41 is parallel to the support beam 31, that is, the load beam 41 is perpendicular to the conveying direction of the conveying part 12. The two ends of the load beam 41 are fixedly connected to the rack 111. The load beam 41 is sleeved with a plurality of material supporting rods 42. The end of the material supporting rod 42 away from the load beam 41 is a free end. The free end of the material supporting rod 42 extends obliquely towards the top of the conveying part 12. The free ends of the plurality of material supporting rods 42 are located on the same horizontal plane above the conveying plane 14. The paperboard entering from the previous process enters at an oblique angle. The oblique paperboard naturally comes into contact with the free end of the material supporting rod 42 when entering, and the automatic material distribution of the paperboard is realized in the process.

[0043] Preferably, the material supporting rod 42 is fixedly connected with the load beam 41, more preferably, the material supporting rod 42 is adjustably connected with the load beam 41, and the material supporting rod 42 is rotatably connected with the load beam 41, that is, the material supporting rod 42 rotates along the central axis of the load beam 41 to adjust the angle of the material supporting rod 42. The material supporting rod 42 is provided with a second locking bolt 43 which is threadedly connected with the material supporting rod 42, so that the second locking bolt 43 has two states of abutting and disengaging with the load beam 41. When the second locking bolt 43 is tightly fastened to abut the load beam, the material supporting rod 42 is locked with the load beam 41 to stably support the paperboard. When the second locking bolt 43 is disengaged from the load beam 41, the material supporting rod 42 slides relative to the load beam 41 to adjust the elevation angle of the material supporting rod 42 and the spacing of adjacent material supporting rods 42.

[0044] The free end of part of the material supporting rod 42 is rotatably connected with a rotor 44 which is in rolling contact with the paperboard, so that the movement of the paperboard is smooth and the influence of static friction on the paperboard feeding is reduced. The free end of part of the material supporting rod 42 is rotatably connected with a supporting plate 45 to support and hold the paperboard, so that the paperboard is kept stable and steady during the conveying process.

[0045] The material supporting rod 42, the sliding member 21 and the supporting rod 32 are sequentially arranged along the movement direction of the conveying part 12. The paperboard enters the conveying part 12 from the end close to the material supporting rod 42. Under the lifting of the material supporting rod 42, the paperboard is arranged in an inclined manner and moves towards the conveying part 12. During this process, the paperboard is separated to make the paperboard enter the conveying belt one by one. When the paperboard moves to the sliding member 21, the gap between the sliding member 21 and the conveying part 12 is only for one paperboard to pass through, so that the paperboard is intercepted again to ensure that the paperboard can pass through one by one. The side wall of the sliding member 21 close to the conveying part 12 is arranged in an inclined manner towards the material supporting rod 42 to press the intercepted paperboard downward. After the previous paperboard passes through, the intercepted paperboard can also smoothly pass through the gap between the sliding member 21 and the conveying part 12. The rollers 33 on the supporting rod 32 abut the paperboard to make the paperboard adhere to the conveying part 12 to stably and automatically feed.

[0046] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
