Abstract
Description
Technical Field
[0001] This utility model relates to the field of self-cleaning technology for narrow V-belt surfaces, and in particular to a self-cleaning device for rubber-coated narrow V-belt surfaces. Background Technology
[0002] As a core component of power transmission systems, rubber banded narrow V-belts are widely used in high-precision transmission scenarios such as automobile engines, machine tool spindles, and agricultural machinery due to the synchronicity of their banded structure and the high transmission efficiency of narrow V-belts. However, the cleanliness of their surface directly affects the stability of transmission friction and service life.
[0003] Existing cleaning devices often employ a direct brushing method, which has significant technical drawbacks. In the operating environment of narrow V-belt conveyors, hard dust such as metal shavings and sand particles are frequently mixed in with the surface and within the 0.5-2mm gaps, far exceeding the hardness of the rubber substrate. When the brush rotates in direct contact, it "embeds" the dust between the rubber and the bristles, forming a friction interface. Under high-speed rotation, the hard particles exert a "ploughing effect" on the rubber surface, creating 5-20μm micro-scratches and damaging the wear-resistant layer.
[0004] Traditional brushes, due to structural limitations, cannot reach deep into crevices. When brushing, they sweep out and accumulate dust from these crevices, creating a cycle of scraping. This can easily cause the rubber layer to peel off, especially on aging belts, exposing the internal fiber cords. At the same time, the misalignment of the brush against the trapezoidal side can cause localized concentrated pressure, "wedging" dust into the rubber surface, creating deep scratches and increasing the risk of belt failure. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a self-cleaning device for rubber narrow V-belt surfaces, which solves the technical problem that existing technologies use brushes to directly wipe rubber narrow V-belts, which causes dust to become embedded between the brush and the belt, forming a friction interface. This results in the dust plowing the rubber surface, causing scratches and damaging the wear-resistant layer of the rubber narrow V-belt.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a self-cleaning device for a rubber banded narrow V-belt, comprising two pulleys and a banded narrow V-belt connected between the two pulleys, wherein the banded narrow V-belt is provided with a self-cleaning device for completely removing dust from the surface of the banded narrow V-belt.
[0007] The self-cleaning device includes a mounting plate connected to the equipment. A flat suction nozzle is mounted on the front end of the mounting plate, and a negative pressure tube is mounted on the flat suction nozzle. A negative pressure box is mounted on the other end of the negative pressure tube. Multiple slit suction nozzles are arrayed at the bottom of the negative pressure box. The slit suction nozzles have strip-shaped adsorption holes on their sides adjacent to the V-shaped surface of the narrow V-belt. The slit suction nozzles are equipped with anti-clogging components to prevent dust particles from clogging the strip-shaped adsorption holes. The flat suction nozzles are equipped with pre-vibration components to loosen the dust that has hardened in the gaps of the narrow V-belt.
[0008] A further improvement is that the planar suction nozzle has a Y-shaped structure, with a wide-angle opening at the suction nozzle that is adapted to the combined narrow V-belt, the negative pressure tube is a Y-shaped metal tube, the slit suction nozzle has a conical structure, and multiple slit suction nozzles are respectively inserted into the gaps of the combined narrow V-belt.
[0009] A further improvement is that anti-reverse plates are symmetrically and obliquely installed on the inner walls of both sides of the flat suction nozzle.
[0010] A further improvement is that the anti-clogging component includes an electric telescopic rod installed on the side of the gap suction nozzle, a connecting plate fixed to the end of the electric telescopic rod, a push-pull plate installed on the connecting plate, and the push-pull plate slidingly in the groove of the gap suction nozzle. A top plate is rotatably connected to the push-pull plate through a rotating shaft, and an elastic metal sheet is installed on the inner wall of the push-pull plate.
[0011] A further improvement is that the connecting plate is parallel to the inclined facet of the slit suction nozzle, and the top plate is adapted to the strip-shaped suction hole.
[0012] A further improvement is that the pre-vibration assembly includes a mounting base installed on a flat suction nozzle, vibration springs are symmetrically installed on both sides of the top of the mounting base, vibration plates that fit against the narrow V-belt are installed at the ends of the vibration springs, and a low-frequency vibrator is installed on the mounting base.
[0013] By employing the above technical solution, this utility model provides a self-cleaning device for the surface of a narrow V-belt made of rubber, which has at least the following beneficial effects:
[0014] 1. This utility model connects a negative pressure tube to an external vacuum cleaner, which generates suction. Through the wide-angle opening of the flat nozzle and the slit nozzle inserted into the gap of the narrow V-belt, the dust and impurities on the surface of the narrow V-belt and the adjacent gap are sucked out through the strip-shaped suction holes on the slit nozzle. This avoids dust grinding and scratching the narrow V-belt, accelerating wear of the narrow V-belt, and reducing transmission efficiency.
[0015] 2. This utility model uses an electric telescopic rod to pull the push-pull plate along the slide groove into the gap suction nozzle. At this time, the elasticity of the elastic metal sheet is released, pushing the top plate outward around the pivot, thereby pushing out the dust blocked in the strip suction hole, avoiding the strip suction hole from being blocked and affecting the removal of dust.
[0016] 3. This utility model uses a low-frequency vibrator to drive the vibrating plate to vibrate slightly up and down under the pull of the vibrating spring, thereby causing the narrow V-belt to vibrate slightly, which loosens the clump of dust and improves the efficiency of subsequent negative pressure dust collection.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Example 1
[0032] Currently available technology, which uses a brush to directly wipe the rubber narrow V-belt, causes dust to become embedded between the brush and the belt, creating a friction interface. This leads to the dust ploughing the rubber surface, causing scratches and damaging the wear-resistant layer of the narrow V-belt. This embodiment provides a self-cleaning device for the surface of a rubber banded narrow V-belt. It uses negative pressure adsorption to remove dust from the surface and sides of the banded narrow V-belt, thus avoiding dust scratches caused by direct contact between the brush and the banded narrow V-belt. Please refer to... Figures 1-6 The self-cleaning device for the rubber banded narrow V-belt includes two pulleys 1 and a banded narrow V-belt 2 connected between the two pulleys 1. The banded narrow V-belt 2 is equipped with a self-cleaning device 3 for completely removing dust from the surface of the banded narrow V-belt 2. The self-cleaning device 3 removes dust from the rotating banded narrow V-belt 2 by negative pressure suction, thereby avoiding the problem of dust being pressed into the belt surface and scratched by traditional brushing, as well as the problem of dust not being removed from the gaps between multiple narrow V-belts.
[0033] Because traditional brushing can cause dust to become embedded on the surface of the narrow V-belt 2, scratching its surface during rotation and preventing effective cleaning of dust in the gaps between adjacent narrow V-belts, this device also includes a self-cleaning device 3. The self-cleaning device 3 includes a mounting plate 31 connected to the equipment. A flat suction nozzle 32 is mounted on the front end of the mounting plate 31. A negative pressure tube 33 is mounted on the flat suction nozzle 32. A negative pressure box 34 is mounted on the other end of the negative pressure tube 33. Multiple slit suction nozzles 35 are arrayed at the bottom of the negative pressure box 34. The slit suction nozzles 35 have strip-shaped suction holes 36 on their sides near the V-shaped surface of the narrow V-belt 2. The slit suction nozzles 35 are equipped with anti-clogging components 37 to prevent dust particles from clogging the strip-shaped suction holes 36. The flat suction nozzles 32 are equipped with pre-vibration components 38 to loosen the dust that has hardened in the gaps between the narrow V-belts 2.
[0034] The flat nozzle 32 has a Y-shaped structure with a wide-angle opening at the nozzle end that is adapted to the narrow V-belt 2. The negative pressure tube 33 is a Y-shaped metal tube, and the crevice nozzle 35 has a conical structure. Multiple crevice nozzles 35 are inserted into the gaps of the narrow V-belt 2. The mounting plate 31 is installed on the equipment, ensuring that the flat nozzle 32 is located on the surface of the narrow V-belt 2 and the crevice nozzles 35 are inserted into the gaps of the narrow V-belt 2. At this time, the negative pressure tube 33 is connected to an external vacuum cleaner, which generates suction. Through the wide-angle opening of the flat nozzle 32 and the strip-shaped suction holes 36 on the crevice nozzle 35, dust and impurities on the surface of the narrow V-belt 2 and in the adjacent gaps are sucked out, thereby preventing dust from grinding and scratching the narrow V-belt 2 in the belt body, accelerating the wear of the narrow V-belt 2, and reducing transmission efficiency.
[0035] To prevent dust adsorbed in the flat nozzle 32 from escaping due to airflow interference as it moves toward the negative pressure pipe 33, anti-reverse plates 39 are symmetrically and obliquely installed on the inner walls of both sides of the flat nozzle 32. The two obliquely installed anti-reverse plates 39 form an inverted V-shaped shielding surface, thereby preventing dust from escaping from the flat nozzle 32 and polluting the production environment.
[0036] To prevent larger dust particles from clogging the strip-shaped adsorption holes 36 and affecting the dust removal work in the gap of the narrow V-belt 2 of the coupling, the device is also equipped with an anti-clogging component 37. The anti-clogging component 37 includes an electric telescopic rod 371 installed on the side of the gap suction nozzle 35. A connecting plate 372 is fixedly connected to the end of the electric telescopic rod 371. A push-pull plate 373 is installed on the connecting plate 372 and slides in the groove of the gap suction nozzle 35. A top plate 374 is rotatably connected to the push-pull plate 373 through a rotating shaft. An elastic metal sheet 375 is installed on the inner wall of the push-pull plate 373.
[0037] The connecting plate 372 is parallel to the inclined facet of the crevice nozzle 35, and the top plate 374 is adapted to the strip-shaped suction hole 36. When the sensor built into the crevice nozzle 35 (not shown in the figure) senses that the suction of the strip-shaped suction hole 36 has decreased and is blocked, the electric telescopic rod 371 is activated. The connecting plate 372 pulls the push-pull plate 373 along the slide groove into the crevice nozzle 35. At this time, the elasticity of the elastic metal sheet 375 is released, pushing the top plate 374 outward around the pivot, thereby pushing out the dust blocked in the strip-shaped suction hole 36 and preventing the strip-shaped suction hole 36 from being blocked, which would affect the removal of dust.
[0038] Example 2
[0039] Because the dust on the narrow V-belt 2 may be compacted during rotation and difficult to remove directly, therefore, based on Example 1, as... Figures 1-6 As shown, the device is also equipped with a pre-vibration assembly 38, which includes a mounting base 381 mounted on the flat suction nozzle 32. Vibration springs 382 are symmetrically mounted on both sides of the top of the mounting base 381. Vibration plates 383 that fit against the narrow V-belt 2 are mounted at the ends of the vibration springs 382. A low-frequency vibrator 384 is mounted on the mounting base 381. When the low-frequency vibrator 384 is activated, the vibration plates 383 vibrate slightly up and down under the pull of the vibration springs 382, thereby causing the narrow V-belt 2 to vibrate slightly, thus loosening the clump of dust and improving the efficiency of subsequent negative pressure dust collection.
