[0002] In the production process of cardboard, the formed cardboard needs to be sent into a printing machine for printing packaging on the cardboard surface. After the cardboard is formed, it is usually stacked in piles for easy storage and transportation. For the printing operation of the formed cardboard, manually putting the cardboard into the printing machine one by one not only has safety hazards but also is time-consuming and laborious. Therefore, it is necessary to design a cardboard feeding device to solve this problem. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a cardboard feeding device, which solves the above-mentioned technical problems.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A cardboard feeding device includes a feeding bin. A feeding port is opened at the front end of the feeding bin. A through groove is opened at the bottom of the feeding bin, and the through groove is communicated with the feeding port. Two bearing seats I and two bearing seats II are symmetrically and fixedly installed at the bottom of the feeding bin. A driven shaft is rotatably installed between the two bearing seats I, and a driving shaft is fixedly installed between the two bearing seats II. Roller sleeves are fixedly sleeved on the surfaces of the driven shaft and the driving shaft and are located inside the through groove. One end of the driving shaft is fixedly installed with the output shaft of a motor I, and the motor I is fixedly installed on the surface of the feeding bin. The ends of the driven shaft and the driving shaft far from the motor I are driven by a belt I. A baffle is slidably installed at the front end of the feeding bin, and a transmission component is arranged at the front end of the feeding bin.

[0005] Preferably, a limiting groove is concavely opened on the inner wall of the feeding port. A slider is slidably sleeved on the inner wall of the limiting groove. The two ends of the baffle are symmetrically and fixedly installed with the slider. A T-shaped rod is fixedly installed on the surface of the baffle. The middle line position of the baffle is rotatably installed with a lead screw through a bearing. The T-shaped rods are symmetrically arranged with the lead screw as the center. A fixing plate located above the feeding port is fixedly installed at the front end of the feeding bin. The lead screw penetrates and is threadedly sleeved on the surface of the fixing plate. The T-shaped rod penetrates and is slidably sleeved on the surface of the fixing plate. A scale is arranged at the front end of the feeding bin and is located beside the feeding port. A vertical plate is fixedly installed on the surface of the baffle. A slot is concavely opened inside the feeding bin, and the vertical plate is slidably attached to the inner wall of the slot.

[0006] Preferably, the transmission assembly includes a mounting seat symmetrically and fixedly installed at the front end of the feeding bin. A driven roller and a driving roller are rotatably installed together on the two mounting seats. A conveyor belt is sleeved on the driven roller and the driving roller together. The conveyor belt is located between the two mounting seats. The output shaft of the second motor is fixedly installed at the end of the driving roller. The second motor is fixedly installed on the surface of the mounting seat. The ends of the driven roller and the driving roller away from the second motor are driven by a second belt.

[0007] Preferably, a first support leg is fixedly installed at the bottom of the feeding bin, and a second support leg is fixedly installed at the bottom of the mounting seat. A brake-equipped universal wheel is detachably installed at the bottoms of the first support leg and the second support leg.

[0008] Compared with the related art, a cardboard feeding device provided by the present utility model has the following beneficial effects:

[0009] The present utility model provides a cardboard feeding device. By stacking the cardboard to be fed inside the feeding bin, the cardboard at the lowermost layer contacts the surface of the roller. Subsequently, the first motor is started to drive the driving shaft to rotate, and the driven shaft is driven to rotate synchronously through the transmission of the first belt, so that the rollers on the surfaces of the driven shaft and the driving shaft rotate synchronously, and then the cardboard at the lowermost layer is gradually pushed out from the feeding port. During the process, the upper layer of cardboard is blocked by the baffle, so that when the lowermost layer of cardboard is pushed out, multiple cardboard sheets will not be driven to be pushed out simultaneously due to the weight and friction between the cardboard sheets, effectively ensuring that only one cardboard sheet is pushed out each time, ensuring the feeding quality, eliminating the need for manual placement of cardboard sheets one by one, effectively improving the feeding efficiency of the device, and reducing the labor cost and labor intensity.

[0010] The present utility model provides a cardboard feeding device. When using the rotation of the roller to push out and feed the cardboard, the screw rod is rotated. Due to the limiting effects of the T-shaped rod sliding through the surface of the fixing plate and the slider sliding on the inner wall of the limiting groove, the baffle moves vertically up and down. During the process, the worker can clearly judge the distance between the baffle and the bottom of the feeding port according to the scale, so that when stacking cardboard sheets of different thicknesses for feeding, the height of the baffle can be quickly adjusted, and then the operation of feeding one by one can be smoothly carried out, effectively improving the adaptability of the device.

[0016] Please refer to Figures 1-4 , the present utility model provides a technical solution, including a loading bin 1, a loading opening 24 is opened at the front end of the loading bin 1, a through groove 34 is opened at the bottom of the loading bin 1, the through groove 34 is communicated with the loading opening 24, first bearing seats 12 and second bearing seats 16 are symmetrically and fixedly installed at the bottom of the loading bin 1, a driven shaft 13 is rotatably installed between the two first bearing seats 12, a driving shaft 15 is fixedly installed between the two second bearing seats 16, rollers 35 are fixedly sleeved on the surfaces of the driven shaft 13 and the driving shaft 15 and are located inside the through groove 34, one end of the driving shaft 15 is fixedly installed with the output shaft of a first motor 29, the first motor 29 is fixedly installed on the surface of the loading bin 1, and the ends of the driven shaft 13 and the driving shaft 15 away from the first motor 29 are driven by a first belt 14, a baffle 32 is slidably installed at the front end of the loading bin 1, and a transmission assembly is arranged at the front end of the loading bin 1;

[0017] By stacking the cardboard to be loaded inside the loading bin 1, the cardboard at the lowermost layer contacts the surface of the roller 35. Subsequently, the first motor 29 is started to drive the driving shaft 15 to rotate, and the driven shaft 13 is driven to rotate synchronously through the transmission of the first belt 14, so that the rollers 35 on the surfaces of the driven shaft 13 and the driving shaft 15 rotate synchronously, thereby driving the cardboard at the lowermost layer to be gradually pushed out from the loading opening 24. During the process, the baffle 32 blocks the cardboard at the upper layer, so that when the lowermost cardboard is pushed out, multiple cardboards will not be driven to be pushed out simultaneously due to the weight and friction between the cardboards, effectively ensuring that only one cardboard is pushed out each time, ensuring the loading quality, eliminating the need for manual placement of each cardboard one by one, effectively improving the loading efficiency of the device, and reducing the labor cost and labor intensity.

[0018] The inner wall of the feeding port 24 is recessed to form a limiting groove 25. A sliding block 33 is slidably sleeved on the inner wall of the limiting groove 25. The sliding blocks 33 are symmetrically and fixedly installed at both ends of the baffle 32. A T-shaped rod 27 is fixedly installed on the surface of the baffle 32. The middle line position of the baffle 32 is rotatably installed with a lead screw 28 through a bearing. The T-shaped rods 27 are symmetrically structured with the lead screw 28 as the center. A fixing plate 26 located above the feeding port 24 is fixedly installed at the front end of the feeding bin 1. The lead screw 28 passes through and is threadedly sleeved on the surface of the fixing plate 26. The T-shaped rod 27 passes through and is slidably sleeved on the surface of the fixing plate 26. A scale 3 is arranged at the front end of the feeding bin 1. The scale 3 is located beside the feeding port 24. A vertical plate 31 is fixedly installed on the surface of the baffle 32. A slot 36 is recessed and opened inside the feeding bin 1. The vertical plate 31 is slidably attached to the inner wall of the slot 36;

[0019] When using the roller 35 to rotate to push out and feed the cardboard, measure the thickness A of the thickest cardboard and the thickness B of the thinnest cardboard. After obtaining the stacked height C of the two, rotate the lead screw 28. Due to the limiting effect of the T-shaped rod 27 sliding through the surface of the fixing plate 26 and the sliding block 33 sliding on the inner wall of the limiting groove 25, the baffle 32 moves vertically up and down. During the process, the worker can clearly judge the distance D between the baffle 32 and the bottom of the feeding port 24 according to the scale 3, ensuring that the distance D is less than the height C and greater than or equal to the thickness A (due to actual production needs, the phenomenon that the stacked height of two thinnest cardboards and the stacked height of other thickness cardboards is less than the thickness of the thickest cardboard can be ignored). Thus, when stacking cardboards of different thicknesses for feeding, the height of the baffle 32 can be quickly adjusted, so as to smoothly perform the operation of feeding one by one, effectively improving the adaptability of the device.

[0020] The transmission assembly includes a mounting seat 18. The mounting seats 18 are symmetrically and fixedly installed at the front end of the feeding bin 1. A driven roller 19 and a driving roller 21 are jointly rotatably installed on the two mounting seats 18. A conveyor belt 22 is jointly sleeved on the driven roller 19 and the driving roller 21. The conveyor belt 22 is located between the two mounting seats 18. The end of the driving roller 21 is fixedly installed with the output shaft of a second motor 23. The second motor 23 is fixedly installed on the surface of the mounting seat 18. The ends of the driven roller 19 and the driving roller 21 far from the second motor 23 are driven by a second belt 2;

[0021] After the cardboard is pushed out from the feeding port 24 by the rotation of the roller 35, the pushed-out cardboard is stably placed on the surface of the conveyor belt 22, and the second motor 23 is started to drive the driving roller 21 to rotate through its output shaft. The driven roller 19 rotates synchronously with the driving roller 21 through the transmission of the second belt 2, so that the conveyor belt 22 smoothly feeds the cardboard on its surface into printing and other processes.

[0022] A first support leg 11 is fixedly installed at the bottom of the feeding bin 1. A second support leg 17 is fixedly installed at the bottom of the mounting seat 18. A brake-equipped universal wheel is detachably installed at the bottom of the first support leg 11 and the second support leg 17;

[0023] The overall device is stably supported by the first outrigger 11 and the second outrigger 17, enabling the device to operate smoothly. At the same time, the overall device is made more convenient to move by the detachable brake-equipped universal wheels.
