Description

Technical Field

[0001] This utility model relates to the field of paper processing equipment, and in particular to a novel paper receiver. Background Technology

[0002] In the fields of paper processing, printing, and office supplies, the paper take-up unit is a key piece of equipment used for winding paper, and its performance directly affects the flatness, efficiency, and integrity of the paper winding.

[0003] Traditional paper take-up devices often use bolts to rigidly connect the paper roll sleeve and the shaft. Replacing these devices requires disassembling multiple fasteners, which is time-consuming and reduces work efficiency. Utility Model Content

[0004] The present invention aims to provide a novel paper receiver to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel paper receiver includes a base plate, a vertical plate connected to the base plate, a stepper motor connected to the vertical plate, a rotating shaft connected to the output end of the stepper motor, a paper roll sleeve and a retainer detachably connected to the rotating shaft, a through slot provided in the retainer, a push block slidably connected to the side wall of the through slot, a second spring connected to the push block, the other end of the second spring connected to the side wall of the through slot, a retaining rod connected to the push block, the retaining rod slidably connected to the retainer, a retaining hole provided in the rotating shaft, the retaining rod and the retaining hole cooperating with each other, a support plate connected to the vertical plate, a telescopic rod connected to the support plate, a horizontal plate connected to the telescopic end of the telescopic rod, a fixed seat connected to the horizontal plate, a pressure roller rotatably connected to the fixed seat, the pressure roller cooperating with the paper roll sleeve.

[0007] Preferably, the card holder is connected to a positioning post, the paper roll sleeve is provided with a positioning groove, the positioning post and the positioning groove cooperate with each other, and the positioning post is provided with a guide slope.

[0008] Preferably, the telescopic rod is fitted with a first spring, and the two ends of the first spring are respectively connected to the support plate and the cross plate.

[0009] Preferably, the end of the lever has an arc-shaped structure.

[0010] Preferably, the push block is connected to an anti-slip pad.

[0011] Preferably, the pressure roller is provided with a silicone layer.

[0012] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0013] (1) This solution enables quick assembly and disassembly of the paper roll sleeve and the rotating shaft by setting up a card holder, a push block, a second spring, a card rod, and a card hole. The push block drives the card rod to insert into the card hole of the rotating shaft under the elastic force of the second spring, forming a stable connection. When disassembling, only the push block needs to be pressed manually to compress the second spring so that the card rod can be disengaged from the card hole. No tools are required throughout the process, which solves the problem of cumbersome assembly and disassembly of traditional rigid connections, greatly shortens the replacement time, and effectively improves the overall work efficiency.

[0014] (2) By setting positioning posts and positioning slots, and with the guide slope of the positioning posts, the paper roll sleeve can be quickly aligned with the slot along the slope during installation, ensuring that the positioning posts are accurately embedded in the positioning slots, and achieving coaxial positioning of the paper roll sleeve and the card seat.

[0015] (3) By setting up a telescopic rod, a first spring, a cross plate, and a pressure roller, the elastic potential energy of the first spring is used to provide continuous and adaptive pressure to the pressure roller. When the thickness of the paper roll increases, the pressure roller compresses the telescopic rod and the first spring along with the cross plate, automatically adjusting the pressure. When the paper is thin, the spring force pushes the pressure roller to fit tightly against the paper roll, solving the problem of tearing thin paper or loosening thick paper caused by traditional fixed pressure rollers, and adapting to the winding needs of paper of different thicknesses.

[0016] (4) By setting the arc-shaped structure at the end of the clamp rod, when the clamp rod is inserted into or pulled out of the clamp hole, the arc-shaped surface can reduce the frictional resistance with the inner wall of the clamp hole, avoid the wear of parts caused by rigid collision, extend the service life of the clamp rod and the shaft, and make the disassembly and assembly operation smoother and easier, reducing the difficulty of operation.

[0017] (5) By setting anti-slip pads, operators can increase hand friction when pressing the push block to avoid slipping, ensuring stable force application when disassembling and assembling the paper roll sleeve, improving operational safety and convenience, especially suitable for scenarios where sleeves are frequently changed.

[0018] (6) By setting a silicone layer, the silicone material has good elasticity and wear resistance. When in contact with paper, it can increase friction to prevent slipping and avoid scratches or indentations on the paper surface caused by hard contact, thus protecting the integrity of the paper. It is especially suitable for printing paper, coated paper and other materials with high surface quality requirements. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figure 1-3 The novel paper take-up device shown includes a base plate 3, with a vertical plate 1 connected to one side of the top of the base plate 3. A stepper motor 2 is connected to the vertical plate 1, and a rotating shaft 13 is connected to the output end of the stepper motor 2. The rotating shaft 13 is rotatably connected to the vertical plate 1 through bearings, providing stable rotational power for the paper roll. The stepper motor 2 can precisely control the speed, ensuring a uniform rotation rhythm of the paper roll sleeve 4 and avoiding uneven paper winding density caused by speed fluctuations, thus adapting to the winding needs of paper of different thicknesses. The outer wall of the rotating shaft 13 is detachably connected to a paper roll sleeve 4 and a card holder 11. Each end of the card holder 11 has a through groove 14. Push blocks 12 are slidably connected to the side walls of the two through grooves 14. Each push block 12 is connected to a second spring 15. The other end of each second spring 15 is connected to the corresponding side wall of the through groove 14. Each push block 12 is connected to a locking rod 17. The locking rods 17 are slidably connected to the inner wall of the card holder 11. Each end of the inner wall of the rotating shaft 13 has a locking hole 18. The locking rods 17 and locking holes 18 cooperate with each other. During installation, the elastic force of the second spring 15 pushes the push block 12, causing the locking rod 17 to embed into the locking hole 18, thus achieving rigid fixation between the card holder 11 and the rotating shaft 13. During disassembly, pressing the push block 12 compresses the spring, and the locking rod 17 disengages from the locking hole 18, allowing for separation without the need for tools. A support plate 8 is connected to the top of the upright plate 1. Telescopic rods 9 are evenly connected to the bottom of the support plate 8. All telescopic rods 9 are connected to a horizontal plate 7 at their telescopic ends. Fixed seats 6 are connected to the bottom ends of the horizontal plate 7. The two fixed seats 6 are rotatably connected to a pressure roller 5. The pressure roller 5 cooperates with the paper roll sleeve 4. The pressure roller 5 is tightly fitted to the outer wall of the paper roll sleeve 4, forming a continuous pressure on the paper roll.

[0025] like Figure 3 As shown, positioning posts 19 are connected to both ends of the card holder 11, and positioning grooves 20 are opened at both ends of the paper roll sleeve 4. The two positioning posts 19 cooperate with the corresponding positioning grooves 20. The top of the two positioning posts 19 is provided with guide slopes. The guide slopes guide the sleeve to be quickly inserted, ensuring that the positioning posts 19 are accurately embedded in the positioning grooves 20, so as to achieve coaxial positioning of the paper roll sleeve 4 and the card holder 11.

[0026] like Figure 2As shown, each telescopic rod 9 is fitted with a first spring 10 on its outer wall, and the two ends of each first spring 10 are connected to the corresponding support plate 8 and the cross plate 7, respectively. When the thickness of the paper roll increases, the pressure roller 5 compresses the telescopic rod 9 and the first spring 10 upward with the cross plate 7, and the pressure is adaptively adjusted by the spring force to ensure that the paper remains tight at different winding stages.

[0027] like Figure 3 As shown, both locking rods 17 have arc-shaped ends, which reduces frictional resistance with the hole wall when inserted into or released from the locking hole 18, reduces component wear, and makes disassembly and assembly smoother and less strenuous. Anti-slip pads 16 are connected to the opposite sides of the two pushing blocks 12 to increase hand friction and prevent slippage during operation.

[0028] like Figure 2 As shown, the outer wall of the pressure roller 5 is fitted with a silicone layer. The silicone layer has good elasticity and wear resistance. When in contact with the paper, it can increase friction to prevent slippage and buffer pressure to avoid surface scratches.

[0029] The specific implementation process is as follows:

[0030] When installing the paper roll sleeve 4, the guide slope at the top of the positioning post 19 guides the sleeve to quickly slide into the holder 11. The positioning post 19 is precisely embedded in the positioning groove 20 of the paper roll sleeve 4. At the same time, the second spring 15 in the through groove 14 of the holder 11 pushes the push block 12, so that the locking rod 17 naturally embeds into the locking hole 18 of the rotating shaft 13, completing the rigid connection between the holder 11 and the rotating shaft 13. After starting the stepper motor 2, the motor power is transmitted to the paper roll sleeve 4 through the rotating shaft 13 and the holder 11 in sequence. The sleeve rotates synchronously with the rotating shaft 13, providing stable power for paper winding.

[0031] During the winding operation, after one end of the paper is fixed to the sleeve, the stepper motor 2 drives the rotating shaft 13 to rotate, and winding begins as the sleeve rotates. At this time, the pressure roller 5, under the action of the first spring 10, always presses the surface of the rolled paper. As the thickness of the rolled paper increases, the height is automatically adjusted upward to form an adaptive pressure that matches the thickness of the rolled paper, ensuring that the paper remains tight and flat throughout the winding process. At the same time, the silicone layer of the pressure roller 5 adheres tightly to the surface of the rolled paper through elastic deformation, which both drives the paper to move synchronously through friction and avoids surface damage caused by hard contact. If the rolled paper sleeve 4 needs to be replaced, simply press the push block 12. The push block 12 compresses the second spring 15 and drives the latch 17 to disengage from the latch hole 18 of the rotating shaft 13, releasing the connection between the latch 11 and the rotating shaft 13, and the rolled paper sleeve 4 and the wound paper can be easily removed.

[0032] When replacing the new sleeve, repeat the guiding and inserting action of the positioning pin 19 and the positioning groove 20. After releasing the push block 12, the second spring 15 automatically resets and pushes the locking rod 17 to re-insert into the locking hole 18 to complete the fixing.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
