Description

Technical Field

[0001] The present application relates to the technical field of grinding equipment, and in particular to an easy-to-use sanding belt machine. Background Art

[0002] Abrasives are tools used for grinding, lapping and polishing. They are usually made by fixing abrasives on flexible materials such as paper, cloth, film or composite matrix with adhesives. Common ones are sandpaper and emery cloth. Some small grinders can achieve the grinding effect by equipping the grinding wheel with abrasive belts. They are lightweight, portable and easy to replace.

[0003] Generally, for the convenience of use and easy for users to hold, many handheld grinding tools have appeared on the market to facilitate users to hold and use, and optimize the user's operating feel. For example, a handheld belt sander is a common grinding tool used for surface grinding, polishing and grinding of wood, metal and other materials. Existing belt sanders are usually composed of a sanding belt, a belt sander body, a transmission wheel and a driving wheel. They not only have a good grinding effect, but also are light in weight, which is convenient for users to use anytime and anywhere, and have a wide market.

[0004] However, during the use of the existing hand-held belt sanders, on the one hand, due to the different lengths of the sanding belts, it is not only difficult to adapt to sanding belts of different lengths, but also when installing the sanding belt, the elasticity of the sanding belt itself is not high. Therefore, the user needs to use greater force or use tools to put the sanding belt on the sanding belt machine during installation, which is difficult to operate. In addition, during the use of the belt sander, it is necessary to ensure the stable operation of the sanding belt to reduce the shedding phenomenon of the sanding belt. In addition, when carrying or transporting the existing hand-held belt sanders, they often need to be carried or transported as a whole, which not only takes up a large space, but also during the whole carrying or transportation, if there is vibration of the transport vehicle, etc., the main rod or pulley of the belt sander may be collided or damaged, affecting the subsequent normal operation.

[0005] Therefore, the prior art needs to be further improved and enhanced. Utility Model Content

[0036] In the present application, unless otherwise clearly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example" or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0037] like Figures 1 to 3 As shown, the present application provides an easy-to-use sanding machine, which includes a sanding machine body 10, a hand-held part 20 arranged on one side of the sanding machine body 10, a sanding belt part 30 arranged on the other side, and a sanding belt 40 arranged on the sanding belt part 30, the sanding belt part 30 includes a main rod 31 and a supporting plate 32 arranged on the top of the main rod 31, the supporting plate 32 is detachably connected to the top of the main rod 31, one end of the main rod 31 is connected to the sanding machine body 10, and the other end is hingedly provided with a transmission wheel 33, the wheel surface of the transmission wheel 33 is provided with evenly spaced ridges 34, and the two ends of the sanding belt 40 are respectively sleeved on the sanding machine body 10 and the transmission wheel 33.

[0038] The main body 10 of the sanding machine is made of aluminum alloy to ensure portability and durability. The hand-held part 20 is designed as an ergonomic handle for easy holding and operation by the operator. The main rod 31 of the sanding belt part 30 is made of high-strength stainless steel, and the supporting plate 32 is made of wear-resistant material to adapt to long-term use.

[0039] Furthermore, for the structure of the support plate 32, it can adopt a relatively smooth long strip structure, which is arranged above the sanding machine body 10 and is laid flat on the sanding machine body 10 as a whole, so as to provide a bearing position for the sanding belt 40, and the support plate 32 adopts a detachable connection to facilitate subsequent disassembly and carrying. Its detachable structure can adopt a magnetic setting method, or a bayonet is provided on the top of the sanding machine body 10, and a buckle structure is provided below the support plate 32, and the two are connected. For the support plate 32, in an optional embodiment, the support plate 32 can also be arranged below the sanding machine body 10 to further improve the smoothness of the operation of the sanding belt 40.

[0040] In addition, the transmission wheel 33 is designed to be detachable, which is convenient for replacing worn abrasive belts or performing maintenance. Figure 3 As shown, it presents a gear-like shape, and the extending direction of the ridge 34 is perpendicular to the rotation direction of the transmission wheel 33 .

[0041] Furthermore, if Figure 1 As shown, the belt sander further comprises a mounting seat 35 , a transmission wheel 33 is vertically arranged at the center of the mounting seat 35 , and the mounting seat 35 is hinged to the main rod 31 .

[0042] As for the structure of the mounting seat 35 , it can be configured such that one end of the main rod 31 connected to the sanding machine body 10 is hingedly connected, and the mounting seat 35 and the main rod 31 are hingedly rotated to fit the outer wall of the sanding machine body 10 .

[0043] That is to say, when the present invention is no longer needed and is stored, or when the user carries it to other areas for sanding work, in order to facilitate storage and carrying, the main rod 31 and the main rod 31 and the belt sander body 10 can be folded and installed so that these two places are bent, thereby reducing the overall size.

[0044] In addition, if Figure 1 and Figure 2 As shown, in order to further reduce the size when carried, a sleeve 36 is provided on the side of the main rod 31 close to the sanding machine body 10, and the main rod 31 is slidably connected to the sleeve 36, and the sleeve 36 is hinged to the sanding machine body 10, so that part of the main rod 31 can be stored in the sleeve 36 when not needed.

[0045] It can be understood that by setting the main rod 31 and the sleeve 36 for sliding connection, the main rod 31 can have a telescopic effect. On the one hand, it can adapt to sanding belts 40 of different lengths when in use to adjust the sanding machine. On the other hand, when installing, the main rod 31 can be contracted first and then extended to facilitate the disassembly and assembly of the sanding belt 40, making the operation more convenient. Moreover, the setting of the sleeve 36 can be easily hinged with the sanding machine body 10 to achieve a folding effect. In addition, the present application can also set the mounting seat 35 to have a mounting plate 352, and the mounting plate 352 has a telescopic buckle 353 structure, which can also perform more detailed length adjustment, further facilitating disassembly and adjustment.

[0046] Furthermore, if Figure 3 As shown, the mounting seat 35 includes a connecting base 351 and mounting plates 352 on both sides, the transmission wheel 33 is arranged between the mounting plates 352, and a telescopic buckle 353 is arranged in the middle of the mounting plate 352. The structure of the telescopic buckle 353 can adopt a stretching section structure, and the sleeve 36 and the main rod 31, the telescopic buckle 353 and other structures can be provided with a locking structure, so that when it needs to be extended to a certain length during use, it can be locked to reduce the retraction of the main rod 31 and other structures. For the locking structure, a common locking structure of the extension rod can be adopted, such as an elastic buckle structure or a direct threaded locking structure. This structure is more common and is not specifically limited or described in this application.

[0047] As a preferred embodiment of the present application, the surface of the ridge 34 is provided with an arc surface, and the arc surface is consistent with the curvature of the wheel surface of the transmission wheel 33, so as to ensure sufficient friction while making the rotation smoother, thereby driving the movement of the sanding belt 40 to be smoother.

[0048] In a preferred embodiment, a power group 11 is provided on one side of the sanding machine body 10, and a mounting groove 12 is opened on the other side. A driving wheel 14 is provided in the mounting groove 12. There is a gap 13 between the driving wheel 14 and the inner wall of the mounting groove 12, and friction protrusions are provided on the surface of the driving wheel 14. Multiple friction protrusions are evenly spaced and coaxially arranged with the driving wheel 14.

[0049] like Figure 3 As shown, the power group 11 can be an electric motor, and the driving wheel 14 can be a driving pulley. As for its structure, it can adopt a double-layer structure, with the outer layer being wear-resistant rubber and the inner layer being a metal wheel shaft, so as to improve the service life and wear resistance of the driving wheel 14. The friction protrusions of the driving wheel 14 are made of hard materials to provide sufficient friction to prevent the sanding belt 40 from slipping when running at high speed.

[0050] It is understandable that the height of the friction protrusion on the edge of the driving wheel 14 is higher than the other friction protrusions. By setting the friction protrusions on the surface of the driving wheel 14 and setting the friction protrusions on both sides to be higher, the friction between the sand belt 40 and the driving wheel 14 is increased, and the transmission effect is ensured. At the same time, the higher friction protrusions can form a natural baffle, thereby further ensuring the position of the sand belt 40 during operation, reducing the phenomenon of the sand belt 40 being deflected, and improving the reliability of use.

[0051] In an optional embodiment, a baffle plate is detachably provided on the top of the belt sander body 10. The baffle plate is made of a transparent material, and in order to reduce the impact on the sanding work, the baffle plate can be set to be hinged to facilitate angle adjustment.

[0052] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0053] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
