Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device provided with a flipping assembly. Background Technique

[0002] A feeding machine applies the force of machine movement to materials and transports the materials. The feeding machine is an indispensable equipment in the light industry and heavy industry.

[0003] In the paper processing industry, a paper slitter is an indispensable equipment. When the paper slitter processes the original paper roll, the feeding device is an important part of the paper slitter. The traditional feeding device usually can only feed materials singly. When an original paper roll is used up, it is necessary to stop the machine to replace the new original paper roll, which not only reduces the production efficiency but also increases the labor intensity of the operator. Therefore, a feeding device provided with a flipping assembly is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a feeding device provided with a flipping assembly to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A feeding device provided with a flipping assembly includes two feeding frames. A cross plate is fixed between the two feeding frames. A guiding groove is opened on one side of the cross plate. Support frames are fixed on the outer sides of the two feeding frames. A rotating shaft is rotatably connected between the support frames through bearings. A clamping assembly is arranged on one side of the rotating shaft. When the rotating shaft rotates, it drives the clamping assembly to flip and feed materials; A second motor is fixed on one side of one of the support frames. A second sprocket is fixed at the center of the output shaft end of the second motor; The clamping assembly includes a limiting frame. Fixed frames are fixed at both ends of the limiting frame. A first clamping plate and a second clamping plate are respectively arranged on the outer sides of the fixed frames.

[0007] Preferably, a first sprocket is fixed at the center of one end of the rotating shaft. The second sprocket and the first sprocket are connected by a chain.

[0008] Preferably, a sliding groove is opened inside the fixed frame. A rack penetrating one side of the fixed frame is slidably connected to the inner wall of the sliding groove through a slide rail. One end of the rack is fixed to one side of the first clamping plate.

[0009] Preferably, one side of the second clamping plate is fixed to the outside of the fixed frame. Rubber plates are bonded to the opposite inner sides of the first clamping plate and the second clamping plate.

[0010] Preferably, a first motor and a gear reducer are respectively installed on the inner walls of the above chute. The output shaft end of the first motor is fixed to the input shaft end of the gear reducer, and a gear meshed with one side of the rack is fixed to the output shaft end of the gear reducer.

[0011] Preferably, a limiting block located inside the chute is fixed to one side of the above rack, and the center of the limiting frame is fixedly sleeved on the outer side of the rotating shaft.

[0012] Preferably, a slip ring is sleeved on the outer side of the above rotating shaft. The two ends of the slip ring are fixed to one side of the support frame and the rotating shaft, and the output end of the slip ring is electrically connected to the input end of the first motor.

[0013] Compared with the prior art, the utility model adopts the above technical solutions and has the following technical effects:

[0014] (1) By rotating the output shaft end of the first motor, the output shaft of the first motor drives the gear reducer to rotate. The gear is meshed with the rack, so that the rack slides inside the track groove of the slide rail, and the rack penetrates through the outside of the fixing frame, so that the first clamping plate approaches the second clamping plate. At this time, the first clamping plate and the second clamping plate clamp the original paper roll. The cooperation of the first clamping plate and the second clamping plate, as well as the contact between the rubber plate and the outer side of the original paper roll, provide a stable clamping force, avoid the sliding or displacement of the original paper roll during the feeding process, ensure the processing accuracy, and the rubber plate avoids the direct contact between the first clamping plate and the second clamping plate and the original paper roll, reduces the surface damage of the original paper roll caused by clamping, and protects the quality of the original paper;

[0015] (2) By rotating the output shaft of the second motor, at this time, the output shaft of the second motor drives the second sprocket to rotate. The second sprocket drives the first sprocket to rotate through the chain, and the rotating shaft drives the clamping assembly to rotate, so that another original paper roll is flipped to one side of the feeding end of the paper slitter under the action of the clamping assembly, realizing alternate feeding without stopping for material change, improving the feeding efficiency. Adopting the alternate feeding method, when one original paper roll is fed into the paper slitter for processing, another original paper roll has been prepared by the clamping assembly and can be immediately flipped and sent to the paper slitter. The seamless flipping and feeding reduces the downtime waiting time, thus significantly improving the feeding efficiency. The alternate flipping and feeding ensures that even when one original paper roll is used up, there is no need to stop the machine and wait for a new original paper roll to be installed and clamped, reducing the interruption in the production process and improving the stability and continuity of the production line.

[0025] Embodiment

[0026] Please refer to Figures 1-5 , a feeding device provided with a flipping component, including two feeding frames 1. This feeding device can be applied to the feeding of the base paper roll of a paper slitter. The paper slitter is located on the right side of the feeding frame 1, and the base paper roll enters from the left side of the feeding frame 1. A cross plate 9 is fixed between the two feeding frames 1. The bottom of the feeding frame 1 can be installed with a base. A guiding groove 10 is opened on one side of the cross plate 9. The arc surface of the inner wall of the guiding groove 10 guides the base paper roll. The through groove on one side of the guiding groove 10 between the feeding frames 1 is a space convenient for the flipping of the clamping component 3. Support frames 2 are fixed on the outer sides of the two feeding frames 1. A rotating shaft 4 is rotatably connected between the support frames 2 through bearings. A clamping component 3 is arranged on one side of the rotating shaft 4. When the rotating shaft 4 rotates, it drives the clamping component 3 to perform flipping feeding;

[0027] Specifically, a second motor 6 is fixed on one side of one of the support frames 2. According to the weight of the base paper roll, a gear reduction box 38 can be selected to be added at the output shaft end of the second motor 6. A second sprocket 7 is fixed at the center of the output shaft end of the second motor 6. A first sprocket 5 is fixed at the center of one end of the rotating shaft 4. The second sprocket 7 and the first sprocket 5 are connected by a chain. The output shaft of the second motor 6 drives the second sprocket 7 to rotate. The second sprocket 7 drives the first sprocket 5 to rotate through the chain. The first sprocket 5 drives the clamping component 3 to rotate through the rotating shaft 4. When the first clamping plate 31 and the second clamping plate 32 on one side of one of the fixing frames 34 feed the paper slitter, the first clamping plate 31 and the second clamping plate 32 on one side of the other fixing frame 34 are located on one side of the guiding groove 10. At this time, place another base paper roll on one side of the cross plate 9, so that the first clamping plate 31 and the second clamping plate 32 on one side of the other fixing frame 34 clamp the other base paper roll.

[0028] Specifically, the clamping component 3 includes a limiting frame 35. Fixing frames 34 are fixed at both ends of the limiting frame 35. A first clamping plate 31 and a second clamping plate 32 are respectively arranged on the outer sides of the fixing frames 34. A sliding groove 311 is opened inside the fixing frame 34. A rack 310 passing through one side of the fixing frame 34 is slidably connected to the inner wall of the sliding groove 311 through a slide rail. One end of the rack 310 is fixed to one side of the first clamping plate 31. One side of the second clamping plate 32 is fixed to the outside of the fixing frame 34. Rubber plates 33 are bonded to the opposite inner sides of the first clamping plate 31 and the second clamping plate 32. The first clamping plate 31 and the second clamping plate 32 clamp the base paper roll. When clamping, the rubber plate 33 contacts the outer side of the base paper roll, avoiding the first clamping plate 31 and the second clamping plate 32 directly contacting the base paper board and causing damage to the surface of the base paper roll.

[0029] Specifically, a first motor 37 and a gear reduction box 38 are respectively installed on the inner wall of the sliding groove 311. The output shaft end of the first motor 37 is fixed to the input shaft end of the gear reduction box 38. A gear 39 meshingly connected to one side of the toothed rod 310 is fixed to the output shaft end of the gear reduction box 38. The first clamping plate 31 and the second clamping plate 32 on one side of one of the fixing brackets 34 are located on one side of the guiding groove 10. Then, press the switch to control the rotation of the output shaft end of the first motor 37. The output shaft of the first motor 37 drives the gear reduction box 38 to rotate. A limiting block 36 located inside the sliding groove 311 is fixed to one side of the toothed rod 310. The gear reduction box 38 drives the gear 39 to rotate. At this time, when the gear 39 rotates clockwise, the gear 39 is meshingly connected to the toothed rod 310, so that the toothed rod 310 slides inside the track groove of the sliding rail. The center of the limiting frame 35 is fixedly sleeved on the outer side of the rotating shaft 4.

[0030] Specifically, a slip ring 8 is sleeved on the outer side of the rotating shaft 4. Both ends of the slip ring 8 are fixed to one side of the support frame 2 and the rotating shaft 4. The output end of the slip ring 8 is electrically connected to the input end of the first motor 37. The slip ring 8 is used to supply power to the first motor 37.

[0031] It should be noted that the model of the first motor 37 can be: 1FL6096-1AC61-0AB1;

[0032] The model of the second motor 6 can be: YEJ112M;

[0033] The output shaft ends of the first motor 37 and the second motor 6 both have a brake structure.

[0034] Working principle: When feeding the original paper roll, the original paper roll is installed at the feeding end of the paper slitter. When the original paper roll is slit by the paper slitter, when the worker installs the first original paper roll, first place the original paper roll on the top of the cross plate 9 of the feeding rack 1, and then press the switch to control the rotation of the output shaft of the second motor 6. At this time, the output shaft of the second motor 6 drives the second sprocket 7 to rotate. The second sprocket 7 drives the first sprocket 5 to rotate through the chain. The first sprocket 5 drives the clamping assembly 3 to rotate through the rotating shaft 4. At this time, the first clamping plate 31 and the second clamping plate 32 on one side of one of the fixing frames 34 are located on one side of the guiding groove 10. Then press the switch to control the rotation of the output shaft end of the first motor 37. The output shaft of the first motor 37 drives the gear reduction box 38 to rotate. The gear reduction box 38 drives the gear 39 to rotate. At this time, when the gear 39 rotates clockwise, the gear 39 is meshed and connected with the rack 310, so that the rack 310 slides inside the track groove of the slide rail and the rack 310 extends out of the outside of the fixing frame 34. At the same time, the limit block 36 limits the extension of the rack 310. At this time, manually push the original paper roll so that the original paper roll enters the inside of the first clamping plate 31. Then control the rotation of the output shaft of the first motor 37 again, so that the gear 39 rotates counterclockwise. At this time, the first clamping plate 31 approaches the second clamping plate 32. At this time, the first clamping plate 31 and the second clamping plate 32 clamp the original paper roll. When clamping, the rubber plate 33 contacts the outside of the original paper roll to avoid the first clamping plate 31 and the second clamping plate 32 directly contacting the original paper board and causing damage to the surface of the original paper roll;

[0035] After the clamping assembly 3 clamps the original paper roll at this time, the output shaft of the second motor 6 drives the second sprocket 7 to rotate. The second sprocket 7 rotates with the first sprocket 5 through the chain. At this time, the first sprocket 5 drives the rotating shaft 4 and the limit frame 35 to rotate. When the limit frame 35 rotates, it drives the first clamping plate 31 and the second clamping plate 32 clamping the original paper roll to rotate around the rotating shaft 4. At this time, the original paper roll clamped by the first clamping plate 31 and the second clamping plate 32 is located on the upper right side of the feeding rack 1. The clamping mechanism at the feeding end of the paper slitter clamps both ends of the original paper roll. Then press the switch to rotate the first motor 37. Under the power of the first motor 37, the first clamping plate 31 leaves one side of the second clamping plate 32. At this time, the clamping of the original paper roll is released, so that the original paper roll enters the paper slitter for processing. Through the cooperation of the first clamping plate 31 and the second clamping plate 32, and the contact between the rubber plate 33 and the outside of the original paper roll, a stable clamping force is provided, avoiding the sliding or displacement of the original paper roll during the feeding process and ensuring the processing accuracy;

[0036] When the first clamping plate 31 and the second clamping plate 32 on one side of one of the fixing frames 34 feed the paper cutting machine, the first clamping plate 31 and the second clamping plate 32 on one side of the other fixing frame 34 are located on one side of the guiding groove 10. At this time, place the other base paper roll on one side of the cross plate 9, so that the first clamping plate 31 and the second clamping plate 32 on one side of the other fixing frame 34 clamp the other base paper roll. When the previous base paper roll is fed to the feeding end of the paper cutting machine, under the power of the second motor 6, the other base paper roll is flipped to one side of the feeding end of the paper cutting machine under the action of the clamping assembly 3, realizing alternate feeding without stopping the machine to change materials, improving the feeding efficiency. By adopting the method of alternate feeding, when one base paper roll is fed into the paper cutting machine for processing, the other base paper roll has been prepared by the clamping assembly 3 and can be immediately flipped and sent to the paper cutting machine. The seamless flipping and feeding reduces the downtime waiting time, thus significantly improving the feeding efficiency. The alternate flipping and feeding ensures that even when one base paper roll is used up, there is no need to stop the machine waiting for a new base paper roll to be installed and clamped, reducing the interruption in the production process and improving the stability and continuity of the production line.
