Description

Technical Field

[0001] This utility model relates to a manual composite board cutting machine and rolling cutting method that can realize the rolling extrusion of the cutter fixing frame by the drive tube rolling device, and can quickly complete the grinding of the cutter blade without disassembling the cutter. It belongs to the field of composite board cutting machine manufacturing. Background Technology

[0002] The applicant's prior patent application CN113199522A, entitled "High-performance composite board cutting machine and efficient cutting method", describes a composite board cutting machine in which two guide pillars are fixed at both ends of a guide pillar fixing seat. The blade fixing seat has guide pillar through holes at both ends and is spring-loaded onto the guide pillars. The upper end face of the blade fixing seat has a concentric circular arc groove, and the vertical center line of the concentric circular arc groove is not on the same line as the vertical center line of the guide pillar. There is a drag-reducing roller in the concentric circular arc groove. An eccentric drive tube is located on the drag-reducing roller, and both ends of the eccentric drive tube are eccentrically connected to the guide pillars. The blade is connected to the lower end face of the blade fixing seat, and the vertical line of the blade is the same as the vertical center line of the concentric circular arc groove on the upper end face of the blade fixing seat. The pressure rod is connected to the eccentric drive tube. Its shortcomings are as follows: First, the pressure bar applies downward pressure to drive the eccentric drive tube to rotate. Although the circular surface of the eccentric drive tube theoretically forms a relative rolling downward pressure with the drag-reducing roller located in the concentric circular arc groove on the upper end face of the fixed seat, it has been found in actual use that the drag-reducing roller and the drag-reducing roller located in the concentric circular arc groove cannot form a rolling fit at all. What still occurs is a sliding friction fit, so the frictional resistance is large and it is difficult to cut the composite board. Second, because the composite board is thick, the cutter is easily dulled when cutting the composite board, which leads to increased cutting resistance. Summary of the Invention

[0003] Design objective: To overcome the shortcomings of the prior art, this design is to create a manual composite board cutting machine that can both drive the rolling device to roll and squeeze the cutter holder and quickly grind the cutter blade without disassembling the cutter.

[0004] Design Scheme: To achieve the above design objectives, this utility model, based on the background technology, features: 1. The design of using a rolling device between the drive tube and the upper end face of the cutter fixing frame in a manual composite board cutting machine to transmit the cutting force is one of the technical features of this utility model. The purpose of this design is that, in the implementation of the background technology, the applicant discovered that, theoretically, when the eccentric drive tube, under the action of the handle and pressure rod, forms a relative rolling downward pressure with the resistance-reducing roller located in the arc-shaped groove, the resistance-reducing roller will transfer the vertically downward cutting force to the blade through the blade fixing seat, achieving the purpose of downward vertical cutting. However, because the drag-reducing roller located in the arc groove experiences sliding friction instead of rolling friction under the action of the eccentric drive tube, although this completely solves the problem that when the highest contact pressure line of the drive rod acts on the blade holder, its highest contact pressure line (the maximum point of eccentricity) does not act on the vertical center line of the blade holder, but deviates from the vertical center line of the guide post by 12-13mm, thus forming a vertically downward cutting force, there are still times when the sliding friction between the drag-reducing roller and the arc groove is obstructed, thus failing to affect the formation of the vertical cutting force; secondly, since what actually occurs is sliding friction, the force-saving effect is not obvious. Therefore, the applicant has replaced the drag-reducing roller in the background technology of this utility model with a rolling device, and eliminated the arc groove used in the background technology to adjust the vertical center line of the cutter. This allows the roller shaft in the rolling device to bear the force from the drive tube on top and directly apply this force to the cutter fixing frame to complete the cutting of the composite board. Simultaneously, because the roller shaft in the rolling device rotates clockwise on top and counterclockwise on the bottom, and the clockwise and counterclockwise rotation angles are the same, it not only ensures the vertical downward cutting force of the cutter at all times, but also, in actual calculations, saves 10%-12% more effort than the background technology. 2. The design of the cutter being completely exposed between the guide pillars at the top of the fixing frame is the second technical feature of this utility model. The purpose of this design is that, for a cutter used to cut composite boards to achieve effort saving and a clean cut, not only is a lever-driven pressure transmission mechanism that saves effort necessary, but the sharpness of the cutter's edge is also a key factor. However, when cutting numerous composite boards, the cutter inevitably becomes dull. The usual practice is to remove the cutter and grind it on a whetstone to sharpen the cutting edge. However, this is not only labor-intensive and time-consuming, but also results in the cutter not being able to be fully restored to its original state after disassembly and reassembly, thus affecting cutting efficiency and cut quality. Secondly, since the cutting edge is ground by hand on an electric grinder, it is impossible for the shape of the cutter to remain unchanged during the grinding process. This is an objective fact, and therefore it is impossible to maintain the consistency of the ground cutting edge and the cutting surface. Consequently, it is impossible to guarantee the consistency of the cut surface of the composite board, resulting in poor cut consistency.This invention features a grinding stone that can slide along a slide rail between the guide pillars. The grinding surface of the grinding stone matches the inclined surface of the cutting edge. Therefore, when the grinding stone moves left and right along the slide rail to grind the cutting edge, it not only saves labor and time, but also ensures the consistency of the grinding amount on the cutting edge surface, thereby ensuring the consistency of the cut cross-section of the composite board.

[0005] Technical solution: A roll-type manual composite board cutting machine, comprising a manual composite board cutting machine, wherein the rolling device located between the drive tube and the upper end face of the cutter fixing frame in the manual composite board cutting machine forms a rolling downward pressing engagement with the drive tube and the upper end face of the cutter fixing frame when subjected to force, and the cutter fixed on the upper part of the cutter fixing frame is completely exposed between the guide columns.

[0006] Compared with the prior art, this utility model has two advantages: First, it uses a rolling device as the transmission medium between the drive tube and the cutter fixing frame, which not only saves effort (more than 10% less effort than the prior art), but also ensures that the force of the cutter is vertically downward when cutting the composite board, thus achieving the perpendicularity of the cut surface of the composite board. Second, the grinding design of the grinding stone along the slide rail to grind the cutting edge of the cutter not only saves labor and time, but also ensures the consistency of the grinding amount and the sharpness of the grinding cutter edge.

[0013] Example 1: Refer to Appendix Figure 1-6A manual composite board cutting machine with rolling action includes a rolling device 5 located between the drive tube 2 and the upper surface of the cutter holder 6. When subjected to force, the rolling device 5 forms a rolling downward pressing engagement with the drive tube 2 and the upper surface of the cutter holder 6. The cutter 8, fixed to the upper part of the cutter holder 6, is completely exposed between the guide posts 11. There are no obstructions between the two guide posts 11, such as a grinding stone 15 moving along the slide rail. A length scale 13 and an angle scale 14 are provided on one side of the worktable of the manual composite board cutting machine, and a vernier 12 is provided at the front end of the worktable. A vernier scale needle 18 is provided on the length scale 13.

[0014] The two guide posts 11 have elongated openings on their opposite sides. A return spring 112 and an inner slider 111 are housed within these openings. The lower end of the inner slider 111 rests on the return spring 112. Both ends of the inner slider are connected to the cutter fixing frame 6 for guidance. When the cutter fixing frame is pressed down by an external force, the inner slider 111 is pushed back up to its original position after the force disappears, thereby resetting the cutter fixing frame 6. The two ends of the drive tube 2 are connected to the upper part of the guide posts 11 via drive tube screws 21.

[0015] The cutter holder 6 has a T-shaped structure, and the cutter 8 is fixed to the lower part of the T-shaped cutter holder 6 by cutter fastening screws 7. The T-shaped cutter holder has both high strength and good force transmission characteristics, because the force of the drive tube 2 acting on the roller in the rolling device 4 is directly applied to the middle vertical plate of the T-shaped cutter holder through the roller, which avoids the dispersion of downward pressure and maximizes the force on the cutter fixed at the lower part of the T-shaped cutter holder.

[0016] The rolling device 5 consists of a roller 53, a roller support 52, and an inner shaft 51. The inner shaft 51 passes through the roller 53, and both ends of the inner shaft are located on the roller support 52. The inner shaft 51 has a screw structure, with a nut at one end and a retaining ring at the other end for locking. The lower end of the roller support has a groove-shaped structure and is inserted into the upper end of the cutter fixing frame 6 and then locked with screws. Two sets of rolling devices are fixed on the upper surface of the cutter fixing frame 6.

[0017] The front support seat 10 of the manual composite board cutting machine has a groove extending along its length on its upper end surface. A strip-shaped elastomer 9 is placed inside the groove to protect the cutting blade.

[0018] The front support 10, rear support, and base support bar 16 of the manual composite board cutting machine are connected by quick-release screws 17 for quick assembly or disassembly. The upper surface of the base support 16 has a cutting table. The pressure rod 1 is connected to the drive tube 2 by a handle screw 4 for quick assembly or disassembly. The purpose of this invention is to allow the machine to be divided into three parts after the screws are removed, reducing its volume to one-fifth of the volume required for disassembly and packaging. This makes it convenient to carry, greatly reduces transportation costs, and increases the loading capacity of containers.

[0019] The drive tube 2 is provided with a locking screw 3, which serves to brake and stop the drive tube 2.

[0020] Reference Figure 4 --6. A grinding stone 15 is provided between the guide posts 11, which can slide along the slide rail 19. The grinding surface of the grinding stone 15 matches the bevel of the cutting edge of the cutter 8, so as to complete the grinding of the cutting edge in a standardized, fast and efficient manner.

[0021] When the slide rail is smooth, and the grinding stone is used for manual grinding and cutting, the grinding stone is held on the slide rail by the grinding stone seat, and the surface of the grinding stone matches the beveled edge of the cutting blade. At this time, the manual grinding stone moves back and forth on the slide rail to complete the grinding of the cutting blade edge.

[0022] The rolling cutter method involves placing the composite board on the cutting table when cutting it. During cutting, the pressure bar 1 is manually pressed down by the handle. The pressure bar drives the drive tube 2 to rotate downwards. At the same time, the driving rolling device 5 rotates clockwise relative to the drive tube 2 and rotates counterclockwise relative to the upper end face of the fixed frame 6. In an instant, the cutter 7 fixed at the lower part of the fixed frame 6 cuts the composite board. When the cutter's edge becomes dull, a whetstone is used to quickly grind the cutting edge along the slide rail.

[0023] Example 2: Based on Example 1, when the slide rail is a smooth surface, the grinding stone is electrically ground and the driving power is manual, the grinding stone has a disc-shaped structure and is mounted on the motor shaft. The motor is clamped on the slide rail through the motor base. The surface of the grinding stone matches the beveled edge of the cutting blade. At this time, the motor is started, and the electric grinding stone is manually driven to reciprocate on the slide rail, which can instantly complete the grinding of the cutting blade edge.

[0024] Example 3: Based on Example 1, when the slide rail is a smooth surface and the grinding stone is an electric grinding head, the driving power of which is a motor (preferably a servo motor), the grinding stone has a disc-shaped structure and is mounted on the motor shaft. The grinding stone surface on the electric grinding head matches the beveled edge of the cutter being ground. The motor is secured to the slide rail via a motor mount. The motor mount is an electric drive mount, and the surface inside the electric drive mount that contacts the slide rail is equipped with a drive rubber wheel. Under the drive of the servo motor, the drive rubber wheel drives the electric grinding head located on it to reciprocate along the slide rail. At the same time, the grinding stone surface on the electric grinding head instantly completes the grinding of the cutter's edge.

[0025] Example 4: Based on Example 1, when the slide rail is a toothed surface and the grinding stone is an electric grinding head, the driving power of which is a motor (preferably a servo motor) is used. The grinding stone has a disc-shaped structure and is mounted on the motor shaft. The grinding stone surface on the electric grinding head matches the beveled edge of the cutter being ground. The motor is mounted on the toothed rail through a motor mount. The motor mount is an electric drive mount, which contains gears for meshing with the toothed rail. Under the drive of the motor, the gears drive the electric grinding head located on it to reciprocate along the toothed rail. At the same time, the grinding stone surface on the electric grinding head instantly completes the grinding of the cutter's edge.

[0026] The structural design of electric grinding stones that reciprocate along toothed tracks or slide rails is existing technology and will not be described in detail here.

Any combination, addition, or modification that does not exceed the design concept of this utility model shall fall within the protection scope of this utility model.
