Description

Technical Field

[0001] The present invention relates to a rolling manual composite plate cutting machine and a rolling cutting method, which can realize rolling extrusion of a cutter fixing frame by driving a tube belt rolling device and quickly grind the cutter blade without disassembling the cutter, and belongs to the field of composite plate cutting machine manufacturing. Background Art

[0002] The applicant's prior patent application CN113199522A is named "High-performance composite board cutting machine and efficient cutting method". In the composite board cutting machine, two guide pillars are respectively fixed at the two ends of the guide pillar fixing seat, and guide pillar through holes are opened at both ends of the blade fixing seat and are sleeved on the guide pillars through springs. Concentric circular arc grooves are opened on the upper end face of the blade fixing seat, and the vertical center line of the concentric circular arc grooves is not on the same line as the vertical center line of the guide pillars. There are resistance reduction rollers in the concentric circular arc grooves, an eccentric drive tube is located on the resistance reduction roller, and the two ends of the eccentric drive tube are eccentrically connected to the guide pillars, respectively. 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 grooves on the upper end face of the blade fixing seat, and the pressure rod is connected to the eccentric drive tube. Its shortcomings are: first, the pressure rod 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 on the drag reduction roller located in the concentric circular arc groove on the upper end surface of the fixed seat, it is found in actual use that the drag reduction roller and the drag reduction roller located in the concentric circular arc groove cannot form a rolling fit at all, and a sliding friction fit still occurs, resulting in large friction resistance and laborious cutting of the composite plate; second, due to the thickness of the composite plate, the cutter is easily passivated when cutting the composite plate, resulting in increased cutting resistance. Summary of the invention

[0003] Design purpose: To avoid the shortcomings of the background technology, a rolling manual composite plate cutting machine and rolling cutting method are designed, which can not only realize the rolling extrusion of the cutter fixing frame by driving the tube belt rolling device, but also quickly complete the grinding of the cutter blade without disassembling the cutter.

[0004] Design scheme: In order to achieve the above design objectives. The present invention is based on the background technology: 1. The design of using a rolling device between the drive tube and the upper end surface of the cutter fixing frame in the manual composite board cutting machine to complete the transmission of the cutter force is one of the technical features of the present invention. The purpose of this design is: the applicant found in the implementation of the background technology that, in theory: when the eccentric drive tube forms a relative rolling downward pressure with the resistance reduction roller located in the arc-shaped groove under the action of the handle and the pressure rod, the resistance reduction roller will apply the vertical downward cutting force to the blade through the blade fixing seat, so as to achieve the purpose of downward pressure and vertical cutting. However, due to the sliding friction rather than rolling friction generated by the drag reduction roller located in the arc groove under the action of the eccentric driving tube, although the problem that when the highest contact downward pressure line of the driving rod acts on the blade fixing seat, its highest contact downward pressure line (the maximum eccentric point) does not act on the vertical center line of the blade fixing seat, but deviates from the vertical center line of the guide column by 12-13mm, forming a vertical downward cutting force, but sometimes there is still a situation where the sliding friction between the drag reduction roller and the arc groove is hindered, and the formation of the vertical cutting force cannot be affected; secondly, since sliding friction actually occurs, the labor-saving effect is not obvious. To this end, the applicant changed the resistance-reducing roller in the background technology of the present invention into a rolling device, and eliminated the arc groove used in the background technology to adjust the vertical center line of the cutter, so that the roller in the rolling device bears the force of the driving tube on the upper side and directly acts on the cutter fixing frame on the lower side to complete the cutting of the composite plate. At the same time, since the roller in the rolling device rotates clockwise on the upper side and counterclockwise on the lower side, and the angles of clockwise and counterclockwise rotation are the same, it not only ensures the vertical downward cutting force of the cutter at all times, but also saves 10%-12% of the effort compared with the background technology in actual measurement. 2. The design that the cutter on the upper part of the fixing frame is completely exposed between the guide pillars is the second technical feature of the present invention. The purpose of this design is that the cutter used to cut the composite plate should be labor-saving and have a neat and clean incision. Not only is there a lever pressure transmission mechanism that can save effort, but whether the blade of the cutter can remain sharp is also a key factor. However, the cutter will inevitably become blunt when facing the cutting of many composite plates. The usual practice is to take out the cutter and grind it on a grindstone to make the blade surface of the cutter sharp again. However, frequent operation is not only labor-intensive and time-consuming, but the cutter after disassembly cannot be restored to its original state 100% after reinstallation, which affects the cutting efficiency and the quality of the cut. Secondly, since the cutting edge of the cutter is ground by hand on an electric grinder, and the shape of the cutter being ground cannot be kept unchanged by hand during the grinding process, this is an objective situation, and therefore it is impossible to maintain the consistency of the ground blade surface and the edge surface, and thus it is impossible to ensure the consistency of the cross-section of the cut composite board, resulting in poor consistency of the cut of the cut composite board.The present invention provides a grindstone that can slide along the slide rail between the guide columns, and the grinding surface of the grindstone matches the inclined surface of the cutting blade. Therefore, when the grindstone moves left and right along the slide rail to grind the cutting blade surface, it not only saves labor and time, but also can ensure the consistency of the grinding amount of the cutting edge surface of the ground cutting blade, thereby ensuring the consistency of the cut section of the cut composite board.

[0005] Technical Solution 1: A rolling type manual composite board cutting machine, including a manual composite board cutting machine, in which a rolling device located between a driving tube and an upper end surface of a cutter fixing frame forms a rolling downward fit with the driving tube and the upper end surface of the cutter fixing frame when force is applied, and a cutter fixed on the upper part of the cutter fixing frame is completely exposed between the guide columns.

[0006] Technical Solution 2: A rolling cutting method of a rolling manual composite board cutting machine. When the composite board needs to be cut, the composite board is placed on the cutting table. When cutting, the pressure rod is manually pressed down through the handle on the pressure rod. The pressure rod drives the driving tube to press down and rotate. At this time, the driving rolling device rotates clockwise relative to the driving tube and counterclockwise relative to the upper end surface of the fixed frame. At this moment, the cutting knife fixed at the bottom of the fixed frame cuts the composite board.

[0007] Compared with the background technology, the present invention has the following advantages: firstly, a rolling device is used as a transmission device for the driving tube and the cutter fixing frame, which not only achieves the purpose of labor saving, which is more than 10% labor saving compared with the background technology, but also ensures that the force of the cutter when cutting the composite plate is in a vertical downward cutting, so that the verticality of the cut section of the cut composite plate can be achieved; secondly, the design of grinding the cutting edge of the cutter by the grinding stone along the slide rail not only saves labor and time, but also ensures the consistency and sharpness of the grinding amount of the cutting edge of the cutter.

[0013] Embodiment 1: refer to the attached Figure 1-6 . A rolling type manual composite board cutting machine includes a manual composite board cutting machine, wherein the rolling device 5 located between the driving tube 2 and the upper end surface of the cutter fixing frame 6 in the manual composite board cutting machine forms a rolling downward press fit with the driving tube 2 and the upper end surface of the cutter fixing frame 6 when a force is applied, and the cutter 8 fixed on the upper part of the cutter fixing frame 6 is completely exposed between the guide pillars 11, and there is no obstruction between the two guide pillars 11 to prevent the grinding stone 15 from moving left and right along the slide rail. A length scale 13 and an angle scale 14 are provided on one side of the working table of the manual composite board cutting machine, and a vernier 12 is provided at the front end of the working table. A vernier scale needle 18 is provided on the length scale 13.

[0014] The two guide posts 11 have long openings on their opposite sides, and a reset spring 112 and an inner slider 111 are built into the long openings. The lower end of the inner slider 111 is located on the reset spring 112, and both ends of the inner slider are connected to the cutter fixing frame 6 for guiding. When the inner slider 111 is pressed down by the cutter fixing frame under the action of external force, the inner slider 111 is pushed up and reset after the external force disappears, thereby driving the cutter fixing frame 6 to reset. The two ends of the drive tube 2 are connected to the upper part of the guide post 11 through the drive tube screws 21.

[0015] The cutter fixing frame 6 is in a stem-shaped structure, and the cutter 8 is fixed to the lower part of the stem-shaped cutter fixing frame 6 by a cutter fastening screw 7. The stem-shaped cutter fixing frame has the characteristics of high strength and good force conductivity, because the force exerted by the driving pipe 2 on the roller shaft in the rolling device 4 directly acts on the middle vertical plate of the stem-shaped cutter fixing frame through the roller shaft, which not only avoids the dispersion of the downward pressure, but also maximizes the force exerted on the cutter fixed at the lower part of the stem-shaped cutter fixing frame.

[0016] The rolling device 5 is composed of a roller 53, a roller bracket 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 bracket 52. The inner shaft 51 is a screw structure, one end of which is provided with a nut and the other end is locked with a snap ring. The lower end of the roller bracket is a groove-shaped structure and is plug-fitted with the upper end of the cutter fixing frame 6 and then locked with screws. Two sets of rolling devices are fixed on the upper end surface of the cutter fixing frame 6.

[0017] A groove is formed along the length of the upper end surface of the front support seat 10 of the manual composite board cutting machine, and a strip elastic body 9 is built into the groove to protect the cutting blade.

[0018] The front support seat 10, the rear support seat and the base support bar 16 of the manual composite board cutting machine are connected by quick screws 17 to achieve quick assembly or quick disassembly. The upper end surface of the base support member 16 is provided with a cutting table 11; the pressure rod 1 is connected to the driving tube 2 by the handle screw 4 to achieve quick assembly or quick disassembly. The purpose is to make the present invention can be divided into three parts after the screws are removed, so that the volume can be reduced to one-fifth of the volume required for disassembly and packaging, which is convenient to carry, greatly reduces the transportation cost, and increases the loading capacity of the container.

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

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

[0021] When the slide rail is a smooth surface and the grindstone is used for manual grinding and cutting, the grindstone is clamped on the slide rail through the grindstone seat, and the grindstone surface coincides with the blade inclined surface of the cutter to be ground. At this time, the manual grindstone reciprocates on the slide rail to complete the grinding of the blade surface of the cutter.

[0022] Example 2: On the basis of Example 1, when the slide rail is a smooth surface, the grindstone is an electric grinder and the driving power is manual, the grindstone is a disc-shaped structure and is installed on the motor shaft. The motor is clamped on the slide rail through the motor seat. The grindstone surface coincides with the blade bevel of the cutter to be ground. At this time, start the motor and manually drive the electric grindstone to reciprocate on the slide rail, so that the grinding of the cutter blade can be completed instantly.

[0023] Embodiment 3: On the basis of Embodiment 1, when the slide rail is a smooth surface, the grindstone is an electric grinding head, and its driving power is a motor (preferably a servo motor), the grindstone is a disc-shaped structure and is installed on the motor shaft, the grindstone surface on the electric grinding head coincides with the blade bevel of the cutter to be ground, and the motor is clamped on the slide rail through the motor seat; the motor seat is an electric drive seat, and the surface of the electric drive seat that is used to contact the slide rail is equipped with a driving rubber wheel. The driving rubber wheel drives the electric grinding head located thereon to reciprocate along the slide rail under the drive of the servo motor. At the same time, the grindstone surface on the electric grinding head instantly completes the grinding of the cutter blade.

[0024] Embodiment 4: On the basis of Embodiment 1, when the slide rail is a rack surface, the grindstone is an electric grinding head, and its driving power is a motor (preferably a servo motor), the grindstone is a disc-shaped structure and is installed on the motor shaft, the grindstone surface on the electric grinding head matches the blade bevel of the cutter to be ground, and the motor is clamped on the rack through the motor seat; the motor seat is an electric drive seat, and the electric drive seat is equipped with a gear for meshing with the rack. When driven by the motor, the gear drives the electric grinding head located thereon to reciprocate along the rack. At the same time, the grindstone surface on the electric grinding head instantly completes the grinding of the blade surface of the cutter.

[0025] The structural design of the electric grinding stone reciprocating along the rack or along the slide rail is a prior art and will not be described in detail here.

[0026] Embodiment 5: On the basis of Embodiment 1 or 2 or 3 or 4, a rolling cutting knife method of a rolling manual composite board cutting machine is provided. When the composite board needs to be cut, the composite board is placed on the cutting table. When cutting, the pressure rod 1 is manually pressed downward by the handle on the pressure rod, and the pressure rod drives the driving tube 2 to press and rotate downward. At the same time, the driving rolling device 5 rotates clockwise relative to the driving tube 2 and presses and rotates counterclockwise relative to the upper end surface of the fixed frame 6. At this moment, the cutting knife 7 fixed at the lower part of the fixed frame 6 cuts off the composite board; when the cutting edge of the cutting knife becomes blunt, a grindstone is used to quickly grind the cutting edge along the slide rail.

Any combination, addition or modification that does not exceed the design ideas of the present invention shall fall within the protection scope of the present invention.
