Description

Technical Field

[0001] This utility model relates to the field of pencil board processing technology, specifically to a high-efficiency automated pencil board cutting and processing device. Background Technology

[0002] A pencil board is a thin wooden board specifically used to make pencil barrels. It's the layer of wood that "grips" the pencil lead, ultimately forming the main body of the pencil barrel. It's made by cutting logs into square sawn blocks, subjecting them to hydrothermal treatment, and then slicing them into pencil boards using a board cutter. In the pencil board cutting and manufacturing process, grooves for the lead are cut into the pencil boards. Two pencil boards are then glued together to hold the lead, and finally, the pencil boards are cut into individual pencil barrels containing the lead.

[0003] According to Chinese Patent CN215511445 U, a pencil board forming device for processing pencils is disclosed, including a mounting platform. The top of the mounting platform is provided with a pencil board body. The inserts on both sides of the bottom of the U-shaped plate are respectively inserted into the slots on both sides of the top of the mounting platform. After the two moving plates move in opposite directions, the locking blocks on the two moving plates are respectively inserted into the inserts in the slots on both sides, so that the U-shaped plate is fixed to the pencil board body and prevents the pencil board body from shifting during processing.

[0004] The above solution uses a U-shaped plate to clamp and fix the pencil board. However, the size of the U-shaped plate is fixed and cannot be adjusted, meaning it can only cut pencil boards of the same size. Similarly, the first and second cutters in the above solution cannot be adjusted, and the processing efficiency is low, affecting the actual use effect. Utility Model Content

[0005] The purpose of this invention is to provide a highly efficient and automated pencil board cutting and processing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency automated pencil board cutting and processing device, comprising a base, a conveyor belt fixedly installed on the base, a support frame fixedly connected to the upper surface of the base, a threaded rod rotatably connected to one end of the inner wall of the support frame, a drive tool holder provided on the outer side of the threaded rod, a tool fixedly connected to the bottom of the drive tool holder, a telescopic frame provided on the drive tool holder, a limiting roller fixedly installed inside the support frame, a limiting roller rotatably connected to the outer side of a bidirectional lead screw, a limiting plate provided on the outer side of the bidirectional lead screw, a connecting plate rotatably connected to the outer side of the bidirectional lead screw, and a fixed connection to one end of a rotating shaft.

[0007] Preferably, the side of the support frame is connected and fixed to the adjusting motor by bolts, the output end of the adjusting motor is connected and fixed to the threaded rod by a coupling, the side of the drive tool holder has a threaded hole, and the drive tool holder is threaded with the outer thread of the threaded rod through the threaded hole.

[0008] Preferably, a circular through hole is provided on the side of the drive tool holder, and the drive tool holder slides with the guide rod through the circular through hole. The two ends of the guide rod are respectively fixedly connected to the inner wall of the support frame. Several evenly distributed mating tool holders are arranged on the outer side of the guide rod, and the mating tool holders are connected to the drive tool holder through a telescopic frame.

[0009] Preferably, the inner wall of the support frame is rotatably connected to one end of the rotating shaft, a torsion spring is sleeved on the outer side of the rotating shaft, and the other end of the rotating shaft is fixedly connected to the connecting plate.

[0010] Preferably, the two ends of the bidirectional lead screw have opposite threads, the limiting plates are symmetrically distributed on both sides of the bidirectional lead screw, and the limiting plates are engaged with the outer threads of the bidirectional lead screw through the central threaded hole.

[0011] Preferably, a groove is provided on the outer side of the limiting roller, and the limiting roller slides in cooperation with the limiting plate through the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model connects the drive blade holder and the mating blade holder through a telescopic frame. By adjusting the motor, the threaded rod rotates, causing the drive blade holder to slide outside the guide rod. The telescopic frame allows the mating blade holder to move synchronously, thus realizing the adjustment of the distance between the drive blade holder and the mating blade holder. This allows the pencil board to cut different specifications, enhancing the actual use effect. The structure is simple and the operation is convenient.

[0014] 2. This utility model also uses a limiting plate set on the outside of the limiting roller. The elastic force of the torsion spring makes the limiting roller fit against the surface of the pencil board, ensuring stable conveying of the pencil board. The limiting roller prevents the pencil board from shifting up and down or loosening during the cutting process. At the same time, the limiting plates on both sides limit the pencil board on both sides, preventing the pencil board from shaking during the cutting process. The distance between the two limiting plates can be adjusted by rotating the bidirectional lead screw, thereby meeting the cutting and processing needs of pencil boards of different widths and thicknesses.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a high-efficiency automated pencil board cutting and processing device, including a base 1, on which a conveyor belt 2 is fixedly installed. A drive motor is installed on the side of the conveyor belt 2, which drives the conveyor belt 2 to rotate for conveying. The conveyor belt 2 is made of rubber, which is easy to clean and has good wear resistance. The upper surface of the base 1 is welded and fixed to a support frame 3, which is an inverted U-shaped frame. The side of the support frame 3 is connected and fixed to an adjusting motor 4 by bolts. The adjusting motor 4 is a stepper motor with a self-locking effect. The output end of the adjusting motor 4 is connected and fixed to a threaded rod 5 through a coupling. The inner wall of the support frame 3 is rotatably connected to one end of the threaded rod 5. The inner wall of the support frame 3 is welded and fixed to both ends of a rectangular protective frame. A rectangular groove is opened on the side of the protective frame for driving the movement of a tool holder 6. The protective frame reduces the influence of dust and pencil board debris on the threaded rod 5, ensuring the smooth and accurate movement of the tool holder 6.

[0022] The drive tool holder 6 has a threaded hole on its side, through which it engages with the outer thread of the threaded rod 5. A circular through hole is also provided on the side of the drive tool holder 6, through which it slides with the guide rod 10. Both ends of the guide rod 10 are welded and fixed to the inner wall of the support frame 3. Several evenly distributed mating tool holders 8 are arranged on the outer side of the guide rod 10. The mating tool holders 8 are connected to the drive tool holder 6 via a telescopic frame 9. The intersection of the telescopic frame 9 is hinged to both the drive tool holder 6 and the mating tool holders 8. Rotation of the threaded rod 5 causes the drive tool holder 6 to move outside the guide rod 10. The telescopic frame 9 drives the mating tool holders 8 to move synchronously, ensuring that the spacing between the mating tool holders 8 and between the drive tool holder 6 and the mating tool holders 8 is adjusted synchronously. This allows for adjustment of the spacing between the drive tool holder 6 and the mating tool holders 8. The bottom of the drive tool holder 6 is welded and fixed to the cutting tool 7, further allowing for adjustment of the spacing between adjacent cutting tools 7. This enables the cutting of different widths of the pencil board.

[0023] A limiting roller 11 is installed inside the support frame 3. The limiting roller 11 is rotatably connected to the outer side of the double-acting lead screw 12 via bearings. The two ends of the double-acting lead screw 12 have opposite threads. Limiting plates 13 are symmetrically distributed on both sides of the double-acting lead screw 12. The limiting plates 13 are threaded to the outer side of the double-acting lead screw 12 through the central threaded hole. The limiting roller 11 has a sliding groove 14 on its outer side, and the limiting roller 11 slides with the limiting plates 13 through the sliding groove 14. By rotating the double-acting lead screw 12, the limiting plates 13 on both sides can be moved. By adjusting the spacing of the limiting plates 13, different specifications of pencil boards can be processed.

[0024] The outer side of the bidirectional lead screw 12 is rotatably connected to the connecting plate 15 via a damping bearing to prevent the bidirectional lead screw 12 from rotating due to vibration during processing. The inner wall of the support frame 3 is rotatably connected to one end of the rotating shaft 16. A torsion spring 17 is sleeved on the outer side of the rotating shaft 16, and the other end of the rotating shaft 16 is welded and fixed to the connecting plate 15.

[0025] The spring force of the torsion spring 17 pushes the limiting roller 11 to work with the conveyor belt 2 to clamp the pencil board, ensuring the conveying effect of the pencil board. At the same time, the rotation of the limiting roller 11 can limit pencil boards of different thicknesses.

[0026] Working principle: In use, the pencil board to be cut is placed on the surface of the conveyor belt 2. The conveyor belt 2 transports the pencil board. When the pencil board passes the limiting roller 11, it pushes the limiting roller 11 to move upward. The elastic force of the torsion spring 17 causes the rotating shaft 16 to drive the torsion spring 17 to rotate until the limiting roller 11 presses the pencil board against the surface of the conveyor belt 2. The limiting plates 13 on both sides limit the pencil board, ensuring that the pencil board is placed horizontally for cutting and preventing the pencil board from shaking or shifting during the cutting process, which would affect the cutting quality. By rotating the bidirectional lead screw 12, the limiting plates 13 on both sides slide synchronously inside the slide groove 14. That is, by adjusting the spacing of the limiting plates 13, pencil boards of different widths are limited.

[0027] By adjusting the motor 4, the threaded rod 5 is rotated, which causes the drive tool holder 6 to move outside the guide rod 10. The telescopic frame 9 drives the mating tool holder 8 to move synchronously, and ensures that the distance between the mating tool holders 8 and between the drive tool holder 6 and the mating tool holder 8 is adjusted synchronously, ensuring the uniformity of pencil board cutting. The cutting distance can be flexibly adjusted by the movement of the drive tool holder 6.
