Description

Technical Field

[0001] This utility model relates to the technical field of sandpaper cleaning devices, specifically a device for cleaning foreign objects from the surface of sandpaper. Background Technology

[0002] In the production process of abrasive cloth, abrasive application is a crucial step that determines its performance. It involves using an adhesive to fix the abrasive grains to the substrate surface, forming a sanded surface with abrasive capabilities. To ensure adequate coverage of the sanded surface, an excessive amount of abrasive is usually supplied. However, some abrasive grains are only temporarily attached to the sanded surface with a small amount of adhesive or mechanical compression, failing to form a stable bond. These poorly bonded abrasive grains are prone to detaching during subsequent processing, transportation, or the initial stages of use, potentially causing problems such as jamming and wear of transmission components.

[0003] Furthermore, during the sanding process, factors such as adhesive splashing, sand bouncing, or electrostatic adsorption on the back of the substrate can cause sand to adhere to the back of the abrasive cloth. In subsequent production, when the abrasive cloth comes into contact with the conveyor rollers, winding devices, etc., the sand on the back will cause continuous wear on the surface of the metal rollers.

[0004] Traditional cleaning methods rely heavily on manual cleaning with simple brushes, which is inefficient and difficult to adapt to the needs of large-scale production. Utility Model Content

[0005] To address the aforementioned shortcomings, this invention proposes a vibrating screening device for laboratory stone materials, aiming to solve these problems.

[0006] To address the aforementioned shortcomings, this utility model proposes a foreign matter cleaning device for abrasive cloth surfaces. By using a sanding surface cleaning component and a back cleaning component, the abrasive surface and the back of the abrasive cloth are cleaned, solving the problem of low efficiency caused by the traditional method of manually cleaning abrasive cloth.

[0007] To achieve this objective, the present invention adopts the following technical solution: A foreign matter cleaning device for abrasive cloth surface includes a frame, wherein the frame includes, in sequence along the movement direction of the abrasive cloth, a feed roller, a first adjusting roller, a second adjusting roller, and a discharge roller; The first adjusting roller is used to press down against the back of the abrasive cloth, the second adjusting roller is used to press against the abrasive surface of the abrasive cloth, and the discharge roller is used to press against the abrasive surface of the abrasive cloth; when the abrasive cloth is located between the first adjusting roller and the second adjusting roller, the abrasive surface is facing down; when the abrasive cloth is located between the second adjusting roller and the discharge roller, the back is facing down. A sand-covered surface cleaning component is provided between the first adjusting roller and the second adjusting roller, and a back cleaning component is provided between the second adjusting roller and the discharge roller; the sand-covered surface cleaning component is used to clean loosely adhered sand and gravel on the sand-covered surface, and the back cleaning component is used to clean sand and gravel on the back side.

[0009] The back cleaning assembly includes a brush roller, a third tension roller, a second brush component, and a second collection frame; The brush roller presses upward against the back of the abrasive cloth, and the third tension roller presses downward against the abrasive surface of the abrasive cloth; the second brush is located at the bottom of the third tension roller, and the third tension roller and the second brush together clamp the abrasive cloth; the second brush is used to clean the back of the abrasive cloth, and the second collection frame is located below the second brush.

[0010] The back cleaning assembly also includes a scraper and a deflector. The scraper is fixedly installed on the frame, and the end of the scraper abuts against the brush roller. The deflector is inclinedly arranged on the frame, with one end of the deflector located below the brush roller and the other end of the deflector located above the second collection frame.

[0011] The first brush component and the second brush component have the same structure. Both the first brush component and the second brush component include a first swing arm, a second swing arm, and a soft bristle bundle. The ends of the first swing arm and the second swing arm are fixedly connected, and the intersection of the first swing arm and the second swing arm is rotatably connected to the frame. The ends of the first swing arm and the second swing arm are provided with the soft hair bundles.

[0012] The included angle between the first swing arm and the second swing arm is in the range of 30-180°.

[0013] The frame is also provided with multiple power components, which are respectively fixedly connected to the feed roller, the first adjusting roller, the first tension roller, the second tension roller, the second adjusting roller, the brush roller, the third tension roller, the discharge roller, the first brush piece, and the second brush piece.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The following is combined with Figures 1 to 2 This invention describes a device for cleaning foreign objects from the surface of sandpaper according to an embodiment of the present invention.

[0022] A foreign matter cleaning device for abrasive cloth surface includes a frame 1, wherein the frame 1 includes, in sequence along the movement direction of the abrasive cloth, a feed roller 2, a first adjusting roller 3, a second adjusting roller 4, and a discharge roller 5; The first adjusting roller 3 is used to press down on the back of the abrasive cloth, the second adjusting roller 4 is used to press down on the abrasive surface of the abrasive cloth, and the discharge roller 5 is used to press down on the abrasive surface of the abrasive cloth; when the abrasive cloth is located between the first adjusting roller 3 and the second adjusting roller 4, the abrasive surface is facing down; when the abrasive cloth is located between the second adjusting roller 4 and the discharge roller 5, the back is facing down. A sand-covered surface cleaning component 6 is provided between the first adjusting roller 3 and the second adjusting roller 4, and a back cleaning component 7 is provided between the second adjusting roller 4 and the discharge roller 5; the sand-covered surface cleaning component 6 is used to clean sand and gravel that are not firmly stuck in the sand-covered surface, and the back cleaning component 7 is used to clean sand and gravel on the back side.

[0023] By cooperating with the first adjusting roller 3 and the second adjusting roller 4, the sandpaper is positioned between the first adjusting roller 3 and the second adjusting roller 4 with the sand-bearing surface facing down. At this time, the sand-bearing surface cleaning component 6 can accurately act on the sand-bearing surface, efficiently cleaning up the loosely adhered sand and gravel, and preventing these easily detached sand and gravel from affecting the grinding effect of the sandpaper in subsequent use.

[0024] Next, the second adjusting roller 4 and the discharge roller 5 cooperate with each other so that when the abrasive cloth is between the second adjusting roller 4 and the discharge roller, the back side of the abrasive cloth faces down. The back cleaning assembly 7 can specifically clean any residual abrasive on the back side of the abrasive cloth, preventing foreign objects on the back side from interfering with the winding, storage or subsequent processing of the abrasive cloth.

[0025] The feed roller 2, the first adjusting roller 3, the second adjusting roller 4 and the discharge roller 5 interact with each other to smoothly guide the abrasive cloth to complete the turning and transmission process. While ensuring that the tension of the abrasive cloth is appropriate, it keeps the abrasive cloth in a relatively stable posture in the cleaning area, so that the cleaning components can play their full role.

[0026] This invention uses a sanding surface cleaning component 6 and a back cleaning component 7 to clean the sanding surface and back of the sanding cloth, solving the problem of low efficiency caused by the traditional manual cleaning of sanding cloth.

[0027] The sand-covered surface cleaning assembly 6 includes a first tension roller 61, a second tension roller 62, a first brush 63, and a first collection frame 64; The first tension roller 61 presses downward against the back of the abrasive cloth, and the second tension roller 62 presses upward against the abrasive surface of the abrasive cloth; the first brush 63 is disposed between the first tension roller 61 and the second tension roller 62, and the first brush 63 is used to clean the abrasive surface of the abrasive cloth; the first collection frame 64 is disposed below the first brush 63.

[0028] The first tension roller 61 presses downward against the back of the abrasive cloth, and the second tension roller 62 presses upward against the abrasive cloth surface, keeping the abrasive cloth between the first tension roller 61 and the second tension roller 62 taut and preventing local fluctuations due to slight vibrations during transmission. This makes the contact pressure between the first brush 63 and the abrasive surface more uniform and the contact range more stable.

[0029] The first collection frame 64 is located below the first brush 63. The loose sand and gravel swept by the first brush 63 will fall directly into the first collection frame 64 below, preventing the sand and gravel from scattering into the device or the production environment, and effectively preventing the scattered sand and gravel from adhering to the sand cloth again and causing secondary pollution.

[0030] The back cleaning assembly 7 includes a brush roller 71, a third tension roller 72, a second brush 73, and a second collection frame 74; The brush roller 71 presses upward against the back of the abrasive cloth, and the third tension roller 72 presses downward against the abrasive surface of the abrasive cloth; the second brush member 73 is located at the bottom of the third tension roller 72, and the third tension roller 72 and the second brush member 73 together clamp the abrasive cloth; the second brush member 73 is used to clean the back of the abrasive cloth, and the second collection frame 74 is disposed below the second brush member 73.

[0031] The brush roller 71 presses upward against the back of the abrasive cloth, effectively cleaning the sand and impurities attached to the back. At the same time, the third tension roller 72 and the second brush component 73 work together to clamp the abrasive cloth. Then, the second brush component 73 is located at the bottom of the third tension roller 72, performing a secondary cleaning of the back of the abrasive cloth.

[0032] The second collection box 74 collects the fallen sand and gravel, which not only allows for the recycling and reuse of the sand and gravel, but also prevents the sand and gravel from scattering inside the device and causing malfunctions.

[0033] The back cleaning assembly 7 also includes a scraper 75 and a diversion plate 76. The scraper 75 is fixedly installed on the frame 1, and the end of the scraper 75 abuts against the brush roller 71. The diversion plate 76 is inclinedly arranged on the frame 1, with one end of the diversion plate 76 located below the brush roller 71 and the other end of the diversion plate 76 located above the second collection frame 74.

[0034] The brush roller 71 presses upward against the back of the sandpaper, thus transferring the sand and gravel from the back of the sandpaper onto the brush. The end of the scraper 75 abuts against the brush roller 71, and the scraper 75 can scrape away the sand and impurities adhering to the brush roller 71 in real time, keeping the brush roller 71 clean at all times. This ensures a continuous and stable cleaning effect on the back of the sandpaper and avoids a decrease in cleaning efficiency due to clogging of the brush roller 71.

[0035] The guide plate 76 is inclined, with one end below the brush roller 71 and the other end above the collection frame, forming a directional transmission channel from the brush roller 71 to the second collection frame 74. The sand scraped off the brush roller 71 by the scraper 75, as well as the impurities that fall directly when the brush roller 71 cleans the back, are received by the guide plate 76 and slide into the second collection frame 74 along the inclined surface, effectively reducing the occurrence of sand scattering outside the second collection frame 74 during the falling process.

[0036] The first brush component 63 and the second brush component 73 have the same structure. Both the first brush component 63 and the second brush component 73 include a first swing arm 8, a second swing arm 81 and a soft bristle bundle 82. The ends of the first swing arm 8 and the second swing arm 81 are fixedly connected, and the intersection of the first swing arm 8 and the second swing arm 81 is rotatably connected to the frame 1. The ends of the first swing arm 8 and the second swing arm 81 are provided with the soft hair bundle 82.

[0037] When the soft bristle bundles 82 of the first swing arm 8 wear and age due to long-term use, resulting in a decrease in cleaning effect, the soft bristle bundles 82 at the end of the second swing arm 81, which were not originally involved in cleaning, can be rotated to make them come into contact with the surface of the sandpaper and take over the cleaning work, thus avoiding the need to replace the entire brush piece immediately due to the damage of a single soft bristle bundle 82.

[0038] The included angle between the first swing arm 8 and the second swing arm 81 is in the range of 30-180°.

[0039] Users can select the first brush part 63 and the second brush part 73 with different angles according to the specifications of the sandpaper and the cleaning requirements.

[0040] When the first swing arm 8 comes into contact with the sandpaper for cleaning, the larger angle causes the second swing arm 81 to naturally tilt at a certain angle. The sand and gravel swept off by the soft bristles 82 of the first swing arm 8 will first fall onto the appropriately positioned second swing arm 81, and then slide down the surface of the second swing arm 81, precisely falling into the corresponding first collection frame 64 or second collection frame 74 below under its guidance. This reduces the splashing and scattering of sand and gravel during the falling process, allowing the collection frames to collect sand and gravel more efficiently.

[0041] When the angle between the first swing arm 8 and the second swing arm 81 is small, the tilt angle of the second swing arm 81 is relatively steep. At this time, the swept-off gravel falls onto the second swing arm 81 and then accumulates within the angle between the first swing arm 8 and the second swing arm 81. Then, by rotating the first brush part 63 / second brush part 73, the accumulated gravel can be poured into the corresponding first collection frame 64 or second collection frame 74.

[0042] The frame 1 is also provided with a plurality of power components 9, which are respectively fixedly connected to the feed roller 2, the first adjusting roller 3, the first tension roller 61, the second tension roller 62, the second adjusting roller 4, the brush roller 71, the third tension roller 72, the discharge roller 5, the first brush component 63, and the second brush component 73. The plurality of power components 9 are respectively used to drive the feed roller 2, the first adjusting roller 3, the first tension roller 61, the second tension roller 62, the second adjusting roller 4, the brush roller 71, the third tension roller 72, the discharge roller 5, the first brush component 63, and the second brush component 73 to rotate.

[0043] Since different components perform different functions during the sandpaper cleaning process, this utility model uses multiple power components 9 to adjust the rotation speed of different components.

[0044] If a single power source drives multiple components through a transmission mechanism, the equipment is highly susceptible to disruptions in the operation of other components due to changes in the load on one component. This invention, by using multiple power components 9 to drive each component independently, allows each component to operate independently according to its own load. Workers can adjust the speeds of the multiple power components 9 in a timely manner to handle various abnormal situations.

[0045] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
