Description

Technical Field

[0001] This invention relates to the field of knife grinding equipment technology, and in particular to a belt grinding knife propulsion mechanism. Background Technology

[0002] With the development of the garment industry, more and more garment production needs to use cutting tables for cutting and processing. However, after a certain period of use, the cutting blades on the cutting table will become dull, and then the cutting blades need to be sharpened regularly to ensure the cutting effect of the cutting blades.

[0003] Currently, belt sharpeners are commonly used in the market to sharpen cutting knives or other knives. The main principle is that a motor drives a high-speed rotating belt to contact the blade and sharpen it. To ensure the quality of sharpening, an electro-proportional valve is usually installed on the belt sharpener to regulate and control the contact pressure between the belt and the blade. This effectively sharpens the blade while preventing excessive pressure that could damage it. However, existing electro-proportional valves are generally expensive, and their operation in complex environments such as sharpening workshops accelerates wear and aging of their components, leading to a decrease in pressure control accuracy and eventually making them unable to meet the demands of high-quality sharpening. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a belt grinding tool propulsion mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A belt abrasive tool propulsion mechanism includes: a belt abrasive tool holder on which an abrasive belt for sharpening tools is mounted; a mounting base on which a transmission rod capable of driving the belt abrasive tool holder to swing is connected; an adjusting plate is mounted on the transmission rod, and the adjusting plate is provided with a spring and a connecting plate, the connecting plate being abutted by the spring to drive the transmission rod to move and drive the belt abrasive tool holder to swing.

[0007] Preferably, the number of adjusting plates is two, and the spring and connecting plate are disposed between the two adjusting plates.

[0008] Preferably, the adjusting plate is threaded onto the transmission rod.

[0009] Preferably, the adjusting plate has a pin hole in the circumferential direction for the pin shaft to pass through, and the pin shaft fixes the adjusting plate to the transmission rod through the pin hole.

[0010] Preferably, the transmission rod is slidably inserted into the mounting base.

[0011] Preferably, a cylinder is mounted on the mounting base, and the piston rod of the cylinder is connected to the connecting plate.

[0012] Preferably, the piston rod and the transmission rod are arranged parallel to each other.

[0013] Preferably, a swing arm is fixed to one side of the belt sander, a sliding groove is provided in the swing arm, and a sliding rod is installed on the transmission rod that extends into the sliding groove and can drive the belt sander to swing.

[0014] Preferably, the swing arm is provided with a sliding plate, the slide groove is elongated and opened on the sliding plate, and the slide rod is inserted laterally into the slide groove.

[0015] Preferably, the belt grinding holder is equipped with a drive motor capable of driving the belt to rotate.

[0016] The beneficial effects of this invention are:

[0017] 1. The connecting plate drives the transmission rod to move through the spring, thereby causing the belt grinding frame to swing. This allows the sanding belt on the belt grinding frame to swing synchronously and contact the tool for grinding. The elastic pressure of the spring is used to control the grinding pressure, thus effectively grinding the tool while avoiding excessive pressure that could damage the tool, thereby improving the grinding quality. Moreover, the structure of this invention is simple, the cost of use is low, and it is suitable for widespread application.

[0018] 2. Install the adjusting plate on the transmission rod, and adjust the outer adjusting plate to adapt the spring force so that the belt grinding holder and belt can always be under appropriate pressure to grind the tool, thereby ensuring the grinding effect of the tool.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0027] like Figures 1-4 As shown, this embodiment discloses a belt grinding tool propulsion mechanism, including: a belt grinding tool holder 1, on which an abrasive belt 12 for grinding tools is installed. The abrasive belt 12 can be multiple and spaced apart and tensioned on the belt grinding tool holder 1. A drive motor 13 capable of driving the abrasive belt 12 to rotate is installed on the belt grinding tool holder 1. The drive motor 13 and the abrasive belt 12 are distributed opposite to each other on both sides of the belt grinding tool holder 1, so that the drive motor 13 drives the abrasive belt 12 to rotate at high speed and grind the tools.

[0028] Mounting base 2, on which a transmission rod 23 is connected, which can drive the belt sander holder 1 to swing. One end of the transmission rod 23 is connected to the belt sander holder 1. The transmission rod 23 can be driven to move linearly. A swing arm 11 is fixed on one side of the belt sander holder 1. A sliding groove 271 is opened in the swing arm 11. A sliding rod 26 is installed on the transmission rod 23, which extends into the sliding groove 271 and can drive the belt sander holder 1 to swing. The sliding rod 26 is threaded to the end of the transmission rod 23 and can extend laterally into the sliding groove 271.

[0029] Specifically, a slide plate 27 is provided on the swing arm 11. The slide plate 27 is detachably installed on the slide plate 27 by screws. The slide groove 271 is elongated and opened on the slide plate 27. The slide rod 26 is inserted laterally into the slide groove 271. The outer periphery of the slide rod 26 fits against the inner wall of the slide groove 271. The slide plate 27 is made of wear-resistant material. When the transmission rod 23 is driven to move, the slide rod 26 slides on both sides of the slide groove 271 to drive the belt grinding holder 1 to swing to both sides, thereby realizing that the belt grinding holder 1 drives the sanding belt 12 to swing closer to the tool for grinding or swing away from the tool.

[0030] To improve the sharpening quality of this embodiment, an adjusting plate 24 is installed on the transmission rod 23. The adjusting plate 24 is provided with a spring 25 and a connecting plate 22. The connecting plate 22 can be driven to abut against the adjusting plate 24 through the spring 25. Thus, by fixing the transmission rod 23 to the adjusting plate 24, the transmission rod 23 can be moved.

[0031] In this embodiment, there are two adjusting plates 24, and the spring 25 and the connecting plate 22 are disposed between the two adjusting plates 24. The spring 25 and the connecting plate 22 abut against the two adjusting plates 24 at the front and back respectively. It can also be understood that the connecting plate 22 abuts against the outer adjusting plate 24 via the spring 25.

[0032] A cylinder 21 is mounted on the mounting base 2. The cylinder 21 is fixed on the mounting base 2 and is arranged parallel to the transmission rod 23. The piston rod 211 of the cylinder 21 is connected to the connecting plate 22 so as to drive the connecting plate 22 to move along the length direction of the transmission rod 23. The piston rod 211 and the transmission rod 23 are arranged parallel to each other.

[0033] The transmission rod 23 is slidably inserted into the mounting base 2. The mounting base 2 guides the displacement of the transmission rod 23 so that the transmission rod 23 can more stably drive the belt grinding holder 1 to swing to both sides.

[0034] When the connecting plate 22 is driven to move to the left (refer to...) Figure 1 (In the direction shown), the connecting plate 22 abuts against the outer adjusting piece 24 via the spring 25 and drives the transmission rod 23 to move to the left. That is, the connecting plate 22 abuts against the transmission rod 23 via the spring 25 and drives the belt grinding holder 1 to swing, so that the sanding belt 12 on the belt grinding holder 1 can swing synchronously and contact the tool for grinding.

[0035] Furthermore, by sleeved with a spring 25 on the transmission rod 23, and by using the spring 25 to elastically press against the adjusting plate 24 on the outside to drive the transmission rod 23 to move linearly laterally, the grinding pressure is controlled. This allows the abrasive belt 12 on the belt grinding holder 1 to maintain a suitable grinding pressure with the tool, thereby effectively grinding the tool while avoiding excessive grinding pressure that could damage the tool, thus improving the quality of grinding. Moreover, this embodiment has a simple structure, low operating cost, and is suitable for widespread application.

[0036] Furthermore, the adjusting plate 24 is mounted on the transmission rod 23, and the force of the spring 25 can be adjusted by moving the adjusting plate 24 on the outside, so that the sanding belt grinding holder 1 and the sanding belt 12 can always be under appropriate pressure to grind the tool, thereby ensuring the grinding effect of the tool.

[0037] In this embodiment, the adjusting plate 24 can also be abutted and fixed on the transmission rod 23. Specifically, the adjusting plate 24 has a pin hole 241 circumferentially provided for the pin shaft to pass through. The pin hole 241 is threaded, and the pin shaft is screwed into the pin hole 241 through the thread so that the pin shaft fixes the adjusting plate 24 on the transmission rod 23 through the pin hole 241. When the adjusting plate 24 needs to be slidably adjusted on the transmission rod 23, the pin shaft can be loosened first, then the adjusting plate 24 can be slid to a suitable position, and then the pin shaft can be tightened to abut and fix the adjusting plate 24 on the transmission rod 23.

[0038] When the grinding of the tool is finished, the cylinder 21 drives the piston rod 211 to retract. At this time, the connecting plate 22 abuts against the adjusting plate 24 on the inner side, thereby driving the transmission rod 23 to move to the right (see reference). Figure 1 (in the direction shown), and drive the belt grinding holder 1 to swing downward to reset.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
