Description

Technical Field

[0001] This utility model relates to the field of paper feeding technology, specifically to an automatic paper feeding device for a corrugated paper production line. Background Technology

[0002] A corrugated paper production line, also known as a corrugated cardboard production line or corrugated board line, is a key production equipment for corrugated box manufacturers. A corrugated paper production line mainly consists of several important parts, including wet end equipment, dry end equipment, paper feeding equipment, and production management system.

[0003] The automatic paper feeding equipment in a corrugated paper production line is a crucial component of the corrugated box production process. This equipment primarily functions to automatically transport raw paper to designated positions on the production line, ensuring continuous operation. It can automatically adjust the paper supply speed and quantity according to the production line's needs to adapt to different production requirements. This automatic paper feeding equipment mainly consists of a raw paper rack: serving as the starting point of the equipment, it stores and transports rolls of raw paper of different specifications. The design of the raw paper rack typically considers the weight and size of the paper, as well as the ease of paper replacement. The conveying system includes conveyor belts, rollers, and other devices used to transport the raw paper from the raw paper rack to designated positions on the production line. The conveying system usually has adjustable speed and tension control functions to ensure smooth paper transport.

[0004] However, due to the high production speed of corrugated cardboard, which often operates 24 hours a day, the clamping heads used to hold the paper rolls are almost always in continuous operation. When the clamping heads work in this environment for a long time, they need to be lubricated frequently to prevent rapid wear and tear and extend their service life. This process is quite cumbersome, and the equipment needs to be shut down to prevent the rotating equipment from injuring the lubrication operators, thus affecting the efficiency of the equipment. Therefore, this does not meet the existing requirements. To address this, we propose an automatic paper feeding device for corrugated paper production lines. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic paper feeding device for a corrugated paper production line, in order to solve the problems mentioned in the background art. Due to the high production speed of corrugated cardboard, which is mostly 24-hour operation, the clamping heads used to hold the paper rolls are almost always working. When the clamping heads work in this environment for a long time, in order to prevent them from wearing out quickly, they need to be lubricated frequently to increase their service life. This process is cumbersome, and when lubricating, the rotating equipment needs to be shut down to prevent injury to the lubrication operator, thus affecting the working efficiency of the equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic paper feeding device for a corrugated paper production line, including a paper feeder, wherein a clamping bracket is installed on both sides of the rear end face of the paper feeder, and a paper roll is provided between the two clamping brackets;

[0007] The clamping bracket has a clamping head on the side facing the paper roll. The clamping head has a clamping head shaft inside the clamping bracket on the side facing the nearest clamping bracket. A stepper motor is fixedly installed inside the clamping bracket on one side of the clamping head shaft. The output shaft of the stepper motor is connected to a first synchronous shaft through a coupling. A threaded rod is connected to the side of the first synchronous shaft facing the paper roll. A first internal threaded sleeve is threaded to the outer surface of the threaded rod. A sealing plate is slidably connected to the outer shell of the clamping bracket on the upper end face of the first internal threaded sleeve. The outer surface of the sealing plate has multiple second oil drip ports.

[0008] The sealing plate is provided with a lubricating oil groove above it, and the lower inner wall of the lubricating oil groove is provided with a plurality of first oil holes whose positions correspond to the second oil holes and whose number is the same.

[0009] The threaded rod facing the paper roll is connected to a second synchronous rotating shaft. A first bevel gear is fixedly sleeved on one side of the outer surface of both the second and first synchronous rotating shafts. The first bevel gear meshes with the second bevel gear. A lifting threaded rod is connected to the axis of the second bevel gear. A second internal threaded sleeve is sleeved on one side of the outer surface of the lifting threaded rod. An L-shaped connecting bracket is fixedly installed on one side of the outer surface of the second internal threaded sleeve. An arc-shaped clamping plate is fixedly installed on the lower end face of the L-shaped connecting bracket. An arc-shaped sponge plate located outside the clamping head rotating shaft is fixedly installed on the lower end face of the two arc-shaped clamping plates.

[0010] Preferably, a control panel is fixedly installed on the outer surface of the paper feeder on one side of the paper roll, and the paper feeder and the stepper motor are electrically connected to the control panel.

[0011] Preferably, the other side of the outer surface of the second internal threaded sleeve is slidably connected to the interior of the clamping bracket, and the internal thread of the second internal threaded sleeve matches the external thread of the lifting threaded rod.

[0012] Preferably, a sealing cover is provided on the upper side inside the lubricating oil groove, and a handle is fixedly installed at the middle position of the upper end face of the sealing cover.

[0013] Preferably, the bottom end of the lifting threaded rod is located inside the housing of the clamping bracket, and the lifting threaded rod located inside the housing of the clamping bracket is connected to the clamping bracket by a roller bearing.

[0014] Preferably, the arc-shaped sponge board is arc-shaped in its entirety, and the arc-shaped sponge board and the arc-shaped clamping plate are fixed together by a high-viscosity adhesive.

[0015] Preferably, a circular cover plate is provided on one side of the stepper motor on the outer surface of the clamping bracket, and the clamping bracket and the circular cover plate are fixed together by screws.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model, when it is necessary to lubricate the shaft of the clamping head that connects the clamping head and the clamping bracket, adds lubricating oil to the inside of the lubricating oil tank, and then starts the stepper motor. The stepper motor moves the second oil droplet on the sealing plate to a position corresponding to the first oil droplet on the lower inner wall of the lubricating oil tank. Then, under the action of gravity, the lubricating oil inside the lubricating oil tank will pass through the first and second oil droplets and drip onto the arc-shaped sponge plate and be absorbed by the arc-shaped sponge plate. When the stepper motor moves the sealing plate, it will simultaneously move the arc-shaped sponge plate downward to contact the shaft of the clamping head. As the shaft of the clamping head rotates, the lubricating oil absorbed by the arc-shaped sponge plate will be evenly coated on the outer surface of the shaft of the clamping head. Through the above technical solution, the shaft of the clamping head can be automatically lubricated without stopping the machine, thereby increasing the functionality of the equipment.

[0018] 2. In this utility model, after the lubrication of the clamping head shaft is completed, the sealing plate is moved back to its original position by rotating the threaded rod in the opposite direction. The arc-shaped sponge plate will move upward synchronously, thereby releasing the contact between the clamping head shaft and the clamping head shaft. Through the above technical solution, the long-term contact between the clamping head shaft and the arc-shaped sponge plate can be prevented, thus preventing the arc-shaped sponge plate from being worn out quickly.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] The stepper motor 9 (model DM542), threaded rod 10 (model M10) and arc-shaped sponge plate 22 (model JH-004) mentioned in this utility model can be obtained from the market or through private customization.

[0026] Please see Figures 1 to 4 An embodiment of this utility model is provided: an automatic paper feeding device for a corrugated paper production line, including a paper feeder 1, with a clamping bracket 4 installed on both sides of the rear end face of the paper feeder 1, and a paper roll 3 disposed between the two clamping brackets 4.

[0027] A clamping head 5 is provided on the side of the clamping bracket 4 facing the paper roll 3. A clamping head shaft 6 located inside the clamping bracket 4 is provided on the side of the clamping head 5 facing the nearest clamping bracket 4. A stepper motor 9 is fixedly installed inside the clamping bracket 4 on one side of the clamping head shaft 6. The output shaft of the stepper motor 9 is connected to a first synchronous shaft 14 through a coupling. A threaded rod 10 is connected to the side of the first synchronous shaft 14 facing the paper roll 3. A first internal threaded sleeve 11 is threadedly connected to the outer surface of the threaded rod 10. A sealing plate 12 that is slidably connected to the outer shell of the clamping bracket 4 is connected to the upper end face of the first internal threaded sleeve 11. A plurality of second oil drip ports 13 are provided on the outer surface of the sealing plate 12.

[0028] A lubricating oil groove 7 is provided above the sealing plate 12, and a number of first oil outlets 8 are provided on the lower inner wall of the lubricating oil groove 7, which are located in the same position as the second oil outlet 13 and are the same number as the first oil outlet 13.

[0029] A second synchronous rotating shaft 15 is connected to the side of the threaded rod 10 facing the paper roll 3. A first bevel gear 16 is fixedly sleeved on one side of the outer surface of both the second synchronous rotating shaft 15 and the first synchronous rotating shaft 14. The first bevel gear 16 meshes with a second bevel gear 17. A lifting threaded rod 18 is connected to the axis of the second bevel gear 17. A second internal threaded sleeve 19 is sleeved on one side of the outer surface of the lifting threaded rod 18. An L-shaped connecting bracket 21 is fixedly installed on one side of the outer surface of the second internal threaded sleeve 19. An arc-shaped clamping plate 20 is fixedly installed on the lower end face of the L-shaped connecting bracket 21. An arc-shaped sponge plate 22 located outside the clamping head rotating shaft 6 is fixedly installed on the lower end face of the two arc-shaped clamping plates 20. When it is necessary to lubricate the clamping head rotating shaft 6 that connects the clamping head 5 and the clamping bracket 4, lubricating oil is added into the lubricating oil groove 7. Then, the stepper motor 9 is started. The stepper motor 9 can drive the first synchronous rotating shaft 14 connected to it and the first synchronous rotating shaft 14. When the threaded rod 10, which is fixed to the threaded rod 10, rotates, the first internal threaded sleeve 11, which is fitted on the outer surface of the threaded rod 10, is fixed to the sealing plate 12. Therefore, the first internal threaded sleeve 11 cannot rotate on its own. When the threaded rod 10 rotates, the first internal threaded sleeve 11, which is threaded to it but cannot rotate on its own, will move back and forth under the drive of the threaded structure. At this time, the first internal threaded sleeve 11 moves towards the paper roll 3. As the first internal threaded sleeve 11 moves, the sealing plate 12, which is fixed to it, will move synchronously until the second oil dripping port 13 on the outer surface of the sealing plate 12 moves to the position corresponding to the first oil dripping port 8 on the inner wall of the lower end of the lubricating oil tank 7. When the second oil dripping port 13 moves to the position corresponding to the first oil dripping port 8, under the action of gravity, the lubricating oil inside the lubricating oil tank 7 will pass through the first oil dripping port 8 and the second oil dripping port 13 and drip onto the arc-shaped sponge plate 22 and be absorbed by the arc-shaped sponge plate 22.

[0030] The other side of the outer surface of the second internal threaded sleeve 19 is slidably connected to the interior of the clamping bracket 4, and the internal thread of the second internal threaded sleeve 19 matches the external thread of the lifting threaded rod 18; during the rotation of the threaded rod 10, the second synchronous rotating shaft 15 fixed to it will rotate synchronously. As the first synchronous rotating shaft 14 and the second synchronous rotating shaft 15 rotate, the two first bevel gears 16 respectively sleeved on the outer surfaces of the first synchronous rotating shaft 14 and the second synchronous rotating shaft 15 will rotate synchronously. The rotating first bevel gear 16 can drive the second bevel gear 17 meshing with it to rotate together, and the rotating second bevel gear 17 can drive the connecting When the lifting threaded rod 18 connected to the shaft of the second bevel gear 17 rotates, the second internal threaded sleeve 19, which is sleeved on the outer surface of the lifting threaded rod 18, is slidably connected to the inside of the clamping bracket 4 on one side. Therefore, the second internal threaded sleeve 19 cannot rotate on its own. When the lifting threaded rod 18 rotates, the second internal threaded sleeve 19, which cannot rotate on its own, will move up and down under the drive of the threaded structure. When the sealing plate 12 is moved toward the paper roll 3, the second internal threaded sleeve 19 will move down. As the second internal threaded sleeve 19 descends, the arc-shaped clamping plate 20, which is connected to it through the L-shaped connecting bracket 21, will move down synchronously.

[0031] The arc-shaped sponge plate 22 is arc-shaped as a whole, and the arc-shaped sponge plate 22 and the arc-shaped clamping plate 20 are fixed together by high-viscosity adhesive. As the arc-shaped clamping plate 20 descends, the arc-shaped sponge plate 22 fixed to the lower end face of the arc-shaped clamping plate 20 will move downward together. When the second oil drop 13 located on the outer surface of the sealing plate 12 moves to the position corresponding to the first oil drop 8, the lower end face of the arc-shaped sponge plate 22 will contact the outer surface of the clamping head shaft 6. Then, as the clamping head shaft 6 rotates, the lubricating oil absorbed by the arc-shaped sponge plate 22 will be evenly applied to the outer surface of the clamping head shaft 6. Through the above technical solution, the lubrication of the clamping head 5 shaft and the clamping head shaft 6 can be automatically performed without stopping the machine, thereby increasing the functionality of the equipment.

[0032] After the lubrication of the clamping head shaft 6 is completed, when the sealing plate 12 is moved back to its original position by rotating the threaded rod 10 in the opposite direction, the arc-shaped sponge plate 22 will move upward synchronously, thereby releasing the contact between it and the clamping head shaft 6. This technical solution prevents prolonged contact between the clamping head shaft 6 and the arc-shaped sponge plate 22, thus preventing rapid wear of the arc-shaped sponge plate 22.

[0033] A control panel 2 is fixedly installed on the outer surface of the paper feeder 1 on one side of the paper roll 3, and the paper feeder 1 and the stepper motor 9 are electrically connected to the control panel 2; the paper feeder 1 and the stepper motor 9 can be controlled through the control panel 2.

[0034] A sealing cover is provided on the upper side inside the lubricating oil tank 7, and a handle is fixedly installed in the middle of the upper end face of the sealing cover; the sealing cover can prevent the lubricating oil inside the lubricating oil tank 7 from being contaminated.

[0035] The bottom end of the lifting threaded rod 18 is located inside the housing of the clamping bracket 4, and the lifting threaded rod 18 located inside the housing of the clamping bracket 4 is connected to the clamping bracket 4 by a roller bearing; improving the roller bearing structure between the lifting threaded rod 18 and the clamping bracket 4 can support the lifting threaded rod 18.

[0036] A circular cover plate is provided on one side of the stepper motor 9 on the outer surface of the clamping bracket 4, and the clamping bracket 4 and the circular cover plate are fixed together by screws; the circular cover plate can protect the internal structure of the clamping bracket 4, and when the internal structure of the clamping bracket 4 fails, the circular cover plate can be removed to repair the internal structure of the clamping bracket 4.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
