Description

Technical Field

[0001] This utility model relates to the technical field of computer cutting bed sharpening devices, and more specifically to a double grinding wheel counter-rotating flat-push sharpening device. Background Technology

[0002] Currently, in the field of computerized cutting machine technology, to improve cutting efficiency, multiple layers of fabric are often stacked and bonded together, with a fabric thickness reaching 6cm. The stacked fabric is very stiff, and the cutting blades of the computerized cutting machine need to be used at high speeds for extended periods. This requires the blades to have excellent wear resistance. Furthermore, after a period of use, the blades become dull, resulting in a rough and uneven cut surface. Replacing the blades with new ones increases production costs. Therefore, it is necessary to sharpen and maintain the blades during the cutting intervals.

[0003] Existing cutting machine sharpening devices, in order to minimize space occupation, use built-in motor-driven sharpening wheels to sharpen cutting tools. However, built-in motor-driven sharpening wheels suffer from high manufacturing costs, slow heat dissipation, and high maintenance costs. To solve these problems, engineers have adopted an external motor-driven cylinder-type double grinding wheel design. Patent No. CN107350907 A discloses a new type of sharpening device for computer cutting machines, including double grinding wheels with parallel axes, a guide shaft, a sharpening spring, and a connecting frame. The sharpening spring is sleeved on the outer circle of the guide shaft, and both ends of the guide shaft are connected to the connecting frame. Elastic elements are used to press the grinding wheels against both sides of the cutting tool, and the high-speed rotating grinding wheels grind the cutting tool. However, this design has a problem: the working principle of the sharpening device uses a cylinder to control the transmission fork, and then uses a sharpening lever and elastic elements to control the sharpening work of the double grinding wheels through the guide rail and transmission wheel. This results in a long force stroke and the grinding wheels not acting on the same straight line, leading to a complex structure, low transmission efficiency, and low sharpening efficiency.

[0004] In view of this, we have invented a double-grinding wheel counter-rotating flat-push grinding device. Utility Model Content

[0005] The purpose of this invention is to provide a double-wheel counter-rotating flat-push grinding device. The horizontal pushing of the grinding device is achieved through a flat-push track plate. The grinding motor and rubber ring drive the transmission connection and rotation between the motor pulley and the grinding wheels, thus realizing the grinding effect of the grinding wheels. This device features high transmission efficiency. During the high-speed operation of the double grinding wheels, the main consumable is the rubber ring, resulting in low manufacturing and maintenance costs. Furthermore, the spaced grinding ring design between the two wheels not only improves processing quality but also extends the service life of the grinding wheels.

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows:

[0007] A dual-grinding wheel counter-rotating flat-push grinding device includes a grinding motor, a transmission pulley shaft, and a flat-push track plate.

Detailed Implementation

[0033] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0034] Example 1

[0035] like Figure 1-6 As shown, a dual-grinding wheel counter-rotating flat-push grinding device includes a grinding motor, a transmission pulley shaft, and a flat-push track plate. The grinding motor is fixed to one side of the flat-push track plate via a motor fixing plate. The side of the flat-push track plate away from the grinding motor has a dual-grinding wheel counter-rotating structure. The transmission pulley shaft protrudes from the motor fixing plate, and two motor pulleys are arranged from top to bottom on the protruding part. The dual-grinding wheel counter-rotating structure includes a connecting plate, two fixing frames, and grinding wheels mounted on the fixing frames. The fixing frames include a column and side plates at both ends of the column. The grinding wheels are mounted between the two side plates via a grinding wheel fixing shaft. The grinding wheel includes a main shaft, a groove, and a number of grinding rings disposed on the surface of the main shaft. The motor pulleys are connected to the grooves on the grinding wheels via rubber rings.

[0036] Furthermore, the flat-push track plate has a slide rail groove on the side opposite to the grinding motor, facilitating horizontal pushing of the grinding device when mounted on a linear guide rail. Even further, the connecting plate and the fixing frame are integrally formed, reducing the installation and disassembly of parts and improving efficiency.

[0037] Furthermore, two rubber rings are provided. Further still, the rubber rings include rubber ring A and rubber ring B; the grinding wheels include grinding wheel A and grinding wheel B; the motor pulleys include motor pulley A and motor pulley B. Even further, motor pulley A is connected to grinding wheel A via rubber ring A, and motor pulley B is connected to grinding wheel B via rubber ring B. Furthermore, the column is also provided with rubber ring positioning grooves. The rubber rings connect the motor pulleys and the grinding wheels. Due to the design of the double grinding wheels, if the rubber rings were designed on the same plane, there would be problems with rubber ring friction and impaired transmission. Therefore, designing two motor pulleys vertically, namely motor pulley A and motor pulley B, can reduce friction between the rubber rings, reduce losses and costs, and then using two rubber rings to drive and fix the two grinding wheels can achieve the purpose of synchronous operation of the two wheels.

[0038] Furthermore, in another embodiment, grinding wheel A and grinding wheel B have the same size specifications, meaning the spacing between two adjacent grinding rings is also the same. Even further, the grinding rings on grinding wheel A and grinding wheel B are spaced apart. To achieve this, grinding wheel A and grinding wheel B are designed with their ends reversed, so that the grinding rings of grinding wheel A are spaced between the grinding rings of grinding wheel B. For easy distinction, the portion of the grinding wheel spindle with more space is called the beginning end, and the other end is called the end end. The grinding wheel A and grinding wheel B are designed with their ends reversed; grinding wheel A is mounted on a fixed frame in a typical manner, with the spindle beginning end, a number of grinding rings, and the spindle end arranged from top to bottom; grinding wheel B is mounted on a fixed frame, with the spindle end, a number of grinding rings, and the spindle beginning end arranged from top to bottom. This creates the spaced arrangement of the grinding rings on grinding wheel A and grinding wheel B. This design significantly improves sharpening efficiency, shortens processing cycles, and helps achieve uniform grinding texture and high-quality machined surfaces, reducing defects such as scratches. Furthermore, the offset design reduces abnormal wear of the grinding wheels, extending their service life and lowering production costs. The dual-wheel counter-rotating structure and connecting components form a Y-shaped fork arm structure with a stable wheel spacing, achieving the shortest possible contact time with the cutting tool for sharpening. The dual-wheel design ensures a constant angle for repeated sharpening, and the spacing between the grinding rings of the dual wheels not only improves processing quality but also extends the lifespan of the grinding wheels.

[0039] Furthermore, the push track plate, motor fixing plate, and connecting plate are provided with a number of threaded holes to facilitate detachable connection between the various components.

[0040] The working principle of this utility model is as follows:

[0041] First, the slide rail groove of the flat-push track plate is engaged on the linear guide rail. Driven by the track motor (not shown in the diagram), the grinding device moves horizontally, pushing it towards and close to the cutting blade. Then, the grinding wheels are fixed to the mounting frame, forming a double-grinding-wheel counter-rotating structure, with motor pulley A connected to grinding wheel A via rubber ring A, and motor pulley B connected to grinding wheel B via rubber ring B. The grinding motor is then started, and the motor pulley drives the grinding wheel spindle to rotate via the rubber ring. Grinding wheels A and B rotate counter-rotatingly, allowing the cutting blade to be ground on the abrasive rings of the two grinding wheels, thus achieving the purpose of grinding and maintaining the cutting blade.
