Description
Technical Field
[0001] This utility model relates to the field of paperboard printing machine technology, and in particular to a belt conveyor paper feeding device. Background Technology
[0002] In the field of printing machinery, the stability and precision of the paper feeding device are crucial. Traditional paper feeding devices mostly use a single roller transport method. This structure has inherent defects: the roller and the paperboard have point contact, the contact area is limited, resulting in insufficient friction.
[0003] This problem is particularly pronounced when conveying small-sized, low-grammage, or smooth-surfaced cardboard. Due to insufficient adhesion, the cardboard is prone to slipping, stalling, or even skewing during transport, severely impacting the final printing or processing quality. This often results in a single machine only being able to handle specific cardboard sizes, limiting its applicability. Faced with diverse production needs, manufacturers are forced to equip themselves with multiple specialized machines, significantly increasing purchase and maintenance costs. Utility Model Content

[0025] The present invention will be further described in detail below with reference to embodiments:
[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0027] like Figures 1 to 8 As shown, a belt conveyor paper feeding device includes: a first mounting frame 1 and a second mounting frame 2 arranged sequentially along the paper feeding direction. The second mounting frame 2 is rotatably connected to the first mounting frame 1, and an adjustment component 3 is provided between the second mounting frame 2 and the first mounting frame 1 to adjust the position of the second mounting frame 2 relative to the first mounting frame 1. A roller conveying component 4 is provided on the side of the first mounting frame 1 near the second mounting frame 2, and a belt conveying component 5 is also provided on the second mounting frame 2.
[0028] This invention solves the industry problem of traditional paper feeding devices struggling to handle different sizes of cardboard, especially small cardboard which is prone to slippage, by combining the belt conveyor assembly 5 with the roller conveyor assembly 4. It provides the belt conveyor assembly 5 with a larger and more uniform contact area and friction, enabling stable gripping and conveying of small cardboard and effectively preventing slippage, stagnation, or skewness during transport. This significantly improves paper feeding accuracy and stability. Simultaneously, the second mounting frame 2 is rotatably connected to the first mounting frame 1 via the adjusting assembly 3, allowing operators to flexibly adjust the relative position between the belt conveyor assembly 5 and the roller conveyor assembly 4 according to the cardboard's thickness, material, or process requirements. This broadens the applicability, makes the machine multi-functional, and reduces operating costs.
[0029] The adjustment assembly 3 includes multiple connecting plates 31. One end of each connecting plate 31 is fixedly connected to the first mounting bracket 1, and the second mounting bracket 2 is rotatably connected to the other end of each connecting plate 31. The adjustment assembly 3 also includes multiple first mounting seats 32, which are disposed on the inner and outer sides of the second mounting bracket 2. The adjustment assembly 3 also includes a first rotating shaft 33 through which multiple first mounting seats 32 and the second mounting bracket 2 are sequentially passed. The first rotating shaft 33 is fixedly connected to the second mounting bracket 2 and can rotate relative to the multiple first mounting seats 32. A second mounting seat 34 is also provided at intervals at any of the outermost first mounting seats 32. A reducer 35 is provided on the second mounting seat 34. The output shaft of the reducer 35 is connected to the first rotating shaft 33 and rotates with it. A first driving member 36 capable of driving its output shaft to rotate is provided on the other side of the reducer 35.
[0030] When adjustment is required, the first drive component 36 is activated, which drives the reducer 25 to move. When the reducer 35 moves, it drives the first rotating shaft 33 to rotate. When the first rotating shaft 33 rotates, it drives the second mounting bracket 2 to swing relative to the multiple first mounting seats 32. Since the second mounting bracket 2 is rotatably connected to the other end of the connecting plate 31, the second mounting bracket 2 can swing relative to the first mounting bracket 1, thereby completing the angle adjustment between the belt conveyor assembly 5 and the roller conveyor assembly 4.
[0031] The adjustment assembly 3 further includes a positioning frame 37 fixedly connected to the second mounting frame 2. The positioning frame 37 has a through groove 371 and a top block 38 that abuts against the wall of the through groove 371. The top block 38 is fixedly connected to the second mounting frame 2. By fixing the top block 38 to the second mounting frame 2 and directly pressing it against the wall of the through groove 371 of the positioning frame 37, the top block 38 is rigidly locked to the second mounting frame 2, facilitating the rotation of the second mounting frame 2 relative to the plurality of first mounting seats 32.
[0032] The second mounting bracket 2 is provided with a protruding post 21, and the connecting plate 31 is provided with a groove for inserting a protruding ring. A locking ring 22 is also provided on the protruding post 21, located on the outer side of the connecting plate 31. Through the insertion and engagement of the protruding post 21 with the groove, and axial fixation by the locking ring 22, the second mounting bracket 2 and the connecting plate 31 can be quickly connected, allowing the second mounting bracket 2 to rotate relative to the connecting plate 31.
[0033] The belt conveyor assembly 5 includes a second rotating shaft 51 and a third rotating shaft 52 disposed within the second mounting frame 2. The second rotating shaft 51 and the third rotating shaft 52 are respectively provided with first transmission wheels 53 in corresponding numbers and positions. A transmission belt 54 is disposed between the first transmission wheels 53 of the second rotating shaft 51 and the first transmission wheels 53 of the third rotating shaft 52, which are spaced apart. A first driven wheel 55 is disposed on the second rotating shaft 51. The second mounting frame 2 is also provided with a second driving member 56. A first driving wheel is disposed on the output shaft of the second driving member 56. A first transmission belt 57 is disposed between the first driving wheel and the first driven wheel 55. The top surface of the second mounting frame 2 is provided with a first clearance groove 23 that can make way for the transmission belt 54. When the second drive unit 56 is started, it drives the first drive wheel to rotate. When the first drive wheel rotates, it drives the first transmission belt 57 to move. When the first transmission belt 57 moves, it drives the first driven wheel 55 to rotate. At this time, the second rotating shaft 51 rotates relative to the second mounting bracket 2. When the second rotating shaft 51 rotates, the first transmission wheel 53 on it drives the transmission belt 54 to move, which in turn drives the first transmission wheel 53 of the third rotating shaft 52 to move. This causes the transmission belt 54 to move continuously, thereby causing the cardboard to move continuously.
[0034] The second mounting bracket 2 is also provided with a support frame 24 that can extend under the transmission belt 54 and support the cardboard. The support frame 24 provides support for the passing cardboard, preventing the cardboard from sagging or collapsing in the suspended area between the two transmission belts 54 due to its own weight or uneven tension, thus ensuring that the cardboard remains flat.
[0035] The roller conveying assembly 4 includes two fourth rotating shafts 41 and two fifth rotating shafts 42 disposed within the first mounting frame 1. The two fourth rotating shafts 41 are spaced apart, and the two fifth rotating shafts 42 are spaced apart, with one of the fifth rotating shafts 42 disposed between the two fourth rotating shafts 41. Conveying rollers 43 are disposed on the two fourth rotating shafts 41 and the two fifth rotating shafts 42, and a second transmission wheel 44 is disposed at the end of each of the fourth rotating shafts 41 and the fifth rotating shafts 42. The second transmission wheel 44 is disposed on the outside of the first mounting frame 1, and a third driving member 45 is also disposed on the first mounting frame 1. A second driving wheel 46 is disposed on the output shaft of the third driving member 45, and a second transmission belt 47 is disposed between the second driving wheel 46 and the second transmission wheel 44. By staggering the two fourth rotating shafts 41 and the two fifth rotating shafts 42, the conveying rollers 43 form densely and evenly distributed support points on the first mounting frame 1, providing sufficient and stable support, effectively preventing the cardboard from bending and deforming, and ensuring that the cardboard is transferred in a flat state.
[0036] The first mounting frame 1 is also provided with a cardboard positioning component 7. The cardboard positioning component 7 includes a bracket 71, which is provided with a plurality of positioning protrusions 711. A support plate 712 is provided at the bottom of the bracket 71. A slot 72 for cardboard to be inserted is formed between the top surface of the support plate 712 and the bottom surface of the plurality of positioning protrusions 711.
[0037] The slot 72 provides space for the cardboard to be transported. When the cardboard is placed in, its rear edge will naturally snap into and abut against the slot 72, thus quickly positioning it before the transport begins, which facilitates the subsequent transfer and conveying of the cardboard.
[0038] The first mounting frame 1 is also provided with a horizontally arranged horizontal plate 11. Multiple lifting motors 12 are provided on the horizontal plate 11. The rotating shaft of the lifting motor 12 is connected to the positioning frame 37. The first mounting frame 1 is provided with a slide rail 13. A slider 14 that can move along the slide rail 13 is provided on the horizontal plate 11. A fourth driving member 15 is fixedly connected to the horizontal plate 11. A sixth rotating shaft 16 that can be driven to rotate is connected to the fourth driving member 15. Both ends of the sixth rotating shaft 16 extend to the slide rail 13, and both ends of the sixth rotating shaft 16 are provided with rotating gears 17 that can follow the rotation. The first mounting frame 1 is also provided with a rack 18 that can mesh with the rotating gears 16. When the fourth driving component 15 is activated, it drives the sixth rotating shaft 16 to rotate. The rotation of the sixth rotating shaft 16 causes the rotating gears 17 at both ends to rotate accordingly. The rotating gears 17 mesh with multiple teeth on the rack 18, allowing the horizontal plate 11 to move back and forth along the first mounting frame 1, thus adapting to cardboard of different lengths. The slide rail 13 cooperates with the slider 14 to guide the horizontal plate 11 to move back and forth relative to the first mounting frame 1. Multiple lifting motors 12 drive the positioning frame 37, allowing the overall position of the positioning frame 37 relative to the horizontal plate 11 to be adjusted. This enables the cardboard to gradually enter the roller conveyor assembly 4 in a direct or inclined manner, and then be transported through the roller conveyor assembly 4.
[0039] The lower ends of the first mounting frame 1 and the second mounting frame 2 are provided with air inlets 8, and the air inlets 8 are provided with air inlets 81. During high-speed paper feeding, the rapid friction between the cardboard and the transmission belt 54 and the conveyor roller 43 easily generates static electricity, causing lightweight or thin cardboard to be adsorbed on the surface of the first mounting frame 1 and the second mounting frame 2, resulting in problems such as poor paper feeding, overlapping, or skewing. By setting up the air inlets 8 and introducing airflow from the air inlets 81, the airflow is blown out from the gap between the first mounting frame 1 and the second mounting frame 2, which can effectively neutralize and dissipate static charge, eliminate static adsorption, and thus ensure smooth paper feeding.
[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
