Description

Technical Field

[0001] The present invention relates to the technical field of detection equipment, in particular to a surface quality detection device for producing impregnated paper. Background Art

[0002] Impregnated paper is made from a blend of non-woven wood pulp, PE, and plant fibers. It boasts exceptional absorbency and solvent resistance, while also being a very economical, low-particle-releasing paper towel. It boasts numerous advantages, including wear resistance, a wide variety of styles, impact resistance, deformation resistance, pollution resistance, flame retardancy, moisture resistance, environmental friendliness, colorfastness, easy installation, and ease of care. It is widely used in cabinets, wardrobes, and laminate flooring veneers. Conventional impregnated paper, after impregnation, drying, cooling, and cutting to length, typically undergoes appearance quality inspection before being transported to the palletizing platform for collection and storage.

[0003] The existing impregnated paper appearance quality inspection device (Announcement No.: CN114965488B) has at least the following disadvantages: the above-mentioned patent uses a limiting mechanism set at both ends of the inspection table. After the impregnated paper is conveyed to the inspection table via a conveyor belt, the two rotating plates of the limiting mechanism are driven by a motor to rotate upward to limit the impregnated paper on the inspection table, ensuring that the impregnated paper as a whole is on the top of the inspection table. If the impregnated paper falls on the inspection table in an irregular state, the upward-rotating extended rotating plate can push the part of the impregnated paper not on the inspection table to move to the inspection table, thereby making the visual camera's inspection of the impregnated paper more accurate and reliable, avoiding the problem that the visual camera cannot identify the part of the impregnated paper that is not on the luminous inspection table, resulting in the visual camera being unable to accurately and reliably capture information such as surface defects of the impregnated paper; since the surface of the impregnated paper is usually exposed to a high wear environment, wear resistance testing is very important. The above-mentioned patent only uses a visual camera to photograph and inspect the surface of the impregnated paper, and cannot test the wear resistance of the impregnated paper.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Refer to the attached Figure 1 -Attached Figure 8, a surface quality inspection equipment for impregnated paper production, including a frame 1, the frame 1 is a U-shaped structure, and a first industrial camera 5 and a second industrial camera 6 are symmetrically installed between the inner walls of the opposite sides of the two ends of the frame 1. The first industrial camera 5 is used to photograph and inspect the surface quality of the impregnated paper when it is not worn, and the second industrial camera 6 is used to photograph and inspect the surface quality of the impregnated paper after it is worn. When either the first industrial camera 5 or the second industrial camera 6 detects that the surface quality of the impregnated paper does not meet the standard, the impregnated paper production line can be shut down so that the technician can re-inspect the surface quality of the impregnated paper in time and adjust the production process of the impregnated paper as needed; two wiping strips 7 are fixedly installed symmetrically between the inner walls of the opposite sides of the frame 1 near the second industrial camera 6, and two groups of detection mechanisms are installed symmetrically between the inner walls of the opposite sides of the frame 1. The detection mechanism includes two synchronous rollers 2 rotatably installed between the inner walls of the opposite sides of the frame 1, and the outer surfaces of the two synchronous rollers 2 are provided with a synchronous belt 3. The outer surface of the synchronous belt 3 is fixedly provided with a rectangular cover 4. A rubber ring is fixedly installed on the outer surface of the cover 4 away from the synchronous belt 3, and a friction mechanism is installed inside the rectangular cover 4.

The inner wall of the frame 1 is fixedly installed with a friction strip 11 that matches the friction wheel 10, and the friction wheel 10 intermittently contacts the friction strip 11. A dyeing mechanism is also installed inside the rectangular cover 4. The rotation centers of the two corresponding synchronous rollers 2 in the two sets of detection mechanisms are fixedly installed with synchronous gears 36, and the two synchronous gears 36 are meshed. A stepping motor 37 is fixedly installed on the outer surface of the frame 1, and the output end of the stepping motor 37 passes through the inner wall of the frame 1 and is fixedly installed to the rotation center of one of the synchronous rollers 2. A support plate 8 is fixedly installed between the inner walls on opposite sides of the frame 1, and one side of the support plate 8 is in contact with the inner wall of the synchronous belt 3 close to the friction strip 11. The outer surface of the fixed plate 15 is fixedly installed with a first spring rod 16, and the telescopic end of the first spring rod 16 is fixedly installed to the outer surface of the L-shaped plate 17.

[0021] When in use, the corresponding synchronous roller 2 is driven to rotate by the stepping motor 37, so that the synchronous roller 2 drives the corresponding synchronous belt 3 to move. Since the synchronous rollers 2 of the two sets of detection mechanisms are connected through the synchronous gear 36, the synchronous belts 3 of the two sets of detection mechanisms can move synchronously relative to each other, so that the rectangular covers 4 installed outside the two synchronous belts 3 can move synchronously toward the impregnated paper, and finally the rectangular covers 4 are fitted to the surface of the impregnated paper and move synchronously with the movement of the impregnated paper, so as to ensure that the wire roller 9 installed in the rectangular cover 4 can perform friction operation on the same position of the impregnated paper, avoiding damage to the other positions of the impregnated paper; when the rectangular cover 4 drives the When the wire roller 9 moves to the friction strip 11, the friction wheel 10 will contact the friction strip 11, so that the friction wheel 10 can drive the wire roller 9 to rotate due to the action of friction, so that the wire roller 9 grinds the surface of the impregnated paper, so as to test the wear resistance of the surface of the impregnated paper; after the rectangular cover 4 installed on the synchronous belt 3 leaves the impregnated paper, the impregnated paper continues to move to the wiping strip 7, so that the wiping strip 7 can wipe off the excess paint adhering to the surface of the impregnated paper, leaving only the paint in the scratch of the impregnated paper, so that the scratch forms a clear contrast with the impregnated paper around it, so that the second industrial camera 6 can shoot and detect the scratch more clearly.

[0022] In this embodiment, the dyeing mechanism includes a fixed tube 12 fixedly mounted between the inner walls of the opposite ends of the rectangular cover 4, and a plurality of atomizing nozzles 14 are evenly fixedly mounted on the outer surface of the fixed tube 12 near the wire roller 9, which are connected to the interior thereof. One end of the fixed tube 12 passes through the outer surface of the rectangular cover 4 and is fixedly mounted with a one-way liquid injection valve 13 that is unidirectionally connected to the interior thereof. The outer surface of the frame 1 is provided with an injection mechanism for intermittently injecting liquid into the interior of the fixed tube 12, and the injection mechanism includes a movable plate 18 slidably mounted on the outer surface of the frame 1, and the outer surface of the movable plate 18 is slidably mounted with a C-shaped tube 19 that matches the one-way liquid injection valve 13, and the outer surface of the movable plate 18 is fixedly mounted with an L-shaped Plate 17, the outer surface of the L-shaped plate 17 is fixedly installed with a liquid injection pipe 26, and a first hose 29 that is mutually conductive is fixedly installed between the liquid injection pipe 26 and the C-shaped tube 19. A liquid storage tank 28 is fixedly installed on the outer surface of the frame 1, and a second hose 27 that is mutually conductive is fixedly installed between the liquid storage tank 28 and the liquid injection pipe 26. A first one-way valve that is unidirectionally conductive to the inside of the C-shaped tube 19 is installed on the first hose 29, and a second one-way valve that is unidirectionally conductive to the inside of the liquid injection pipe 26 is installed on the second hose 27. The outer surfaces of both ends of the C-shaped tube 19 are fixedly installed with limit rings 20, and the outer surfaces of both ends of the C-shaped tube 19 are sleeved with compression springs 21, which are arranged between the limit ring 20 and the movable An extrusion assembly is installed between the plates 18, between the frame 1 and the C-shaped tube 19, and the extrusion assembly includes a support frame 23 fixedly mounted on the outer surface of the frame 1, and a pressure plate 24 is fixedly mounted on the outer surface of the support frame 23. The end of the pressure plate 24 close to the first industrial camera 5 is rotated by the torsion shaft to install an inclined plate 25, and the outer surface of the limit ring 20 is fixedly mounted with a guide column 22 corresponding to the inclined plate 25. An injection assembly is installed between the frame 1 and the injection pipe 26, and the injection assembly includes a fixed plate 15 fixedly mounted on the outer surface of the frame 1, and a sleeve 34 is fixedly mounted on the outer surface of the fixed plate 15 close to the injection pipe 26. A movable rod 33 is inserted into the interior of the sleeve 34, and the movable rod 33 is close to the outer surface of the fixed plate 15. A retaining ring 35 is fixedly installed at one end of the near sleeve 34, and a limiting ring matching the retaining ring 35 is fixedly installed inside the sleeve 34. A piston 32 is fixedly installed at the other end of the movable rod 33, and the piston 32 is slidably installed on the inner wall of the injection tube 26. A synchronization component is installed between the movable plate 18 and the rectangular cover 4. The synchronization component includes a second spring rod 30 fixedly installed on the outer surface of the L-shaped plate 17, and a wedge block 31 is fixedly installed on the telescopic end of the second spring rod 30. The wedge block 31 is arranged to pass through the outer surface of the movable plate 18, and the position of the wedge block 31 corresponds to the position of the rectangular cover 4. The outer surface of the frame 1 is penetrated by a strip opening for the movement of the wedge block 31 and the C-shaped tube 19.

[0023] When the guide post 22 returns to the inclined plate 25, the inclined plate 25 is rotatably mounted on the end of the pressure plate 24 via the torsion shaft, so that the guide post 22 can rotate the inclined plate 25 to a certain angle so that the guide post 22 passes over the inclined plate 25 and returns to its original position.

[0024] When the rectangular cover 4 moves to the wedge block 31, the side of the rectangular cover 4 abuts against the wedge block 31, so that the rectangular cover 4 can push the movable plate 18 as a whole toward the fixed plate 15 through the wedge block 31. When the movable plate 18 drives the C-shaped tube 19 to move to the inclined plate 25, the guide column 22 installed on the outside of the C-shaped tube 19 will abut against the inclined plate 25. Under the guidance of the inclined plate 25, the guide column 22 can drive the C-shaped tube 19 as a whole to move toward the rectangular cover 4, so that the tube mouth of the C-shaped tube 19 can be inserted into the one-way liquid injection valve 13, and the C-shaped tube 19 and the fixed tube 12 are connected to each other, so that the pigment can be injected into the fixed tube 12 through the C-shaped tube 19 later, and the pigment is sprayed onto the wire roller 9 through the atomizing nozzle 14, so that the wire roller 9 can bring the pigment into the scratches on the surface of the impregnated paper, making the scratches more obvious, so that the second industrial camera 6 can more clearly capture and detect the wear state of the impregnated paper.

[0025] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, the paper to be impregnated is passed through the interior of the frame 1 so that the impregnated paper is located between the first industrial camera 5, the second industrial camera 6, the wiping strip 7 and the two sets of detection mechanisms that are symmetrically arranged in the upper and lower directions, so that the first industrial camera 5 and the second industrial camera 6 can photograph and detect the surface quality of the upper and lower sides of the impregnated paper; When the impregnated paper needs to be inspected, the corresponding synchronous roller 2 is driven to rotate by the stepping motor 37, so that the synchronous roller 2 drives the corresponding synchronous belt 3 to move. Since the synchronous rollers 2 of the two sets of detection mechanisms are connected by the synchronous gear 36, the synchronous belts 3 of the two sets of detection mechanisms can move synchronously relative to each other, so that the rectangular covers 4 installed on the outside of the two synchronous belts 3 can move synchronously toward the impregnated paper, and finally the rectangular covers 4 are fitted to the surface of the impregnated paper and move synchronously with the movement of the impregnated paper, so as to ensure that the wire roller 9 installed in the rectangular cover 4 can perform a friction operation on the same position of the impregnated paper, avoiding damage to the rest of the impregnated paper; the impregnated paper polished by the wire roller 9 can be cut and removed later; When the rectangular cover 4 drives the wire roller 9 to move to the friction strip 11, the friction wheel 10 will contact the friction strip 11, so that the friction wheel 10 can drive the wire roller 9 to rotate due to the action of friction, so that the wire roller 9 grinds the surface of the impregnated paper, so as to test the wear resistance of the impregnated paper surface; When the rectangular cover 4 moves to the wedge block 31, the side of the rectangular cover 4 abuts against the wedge block 31, so that the rectangular cover 4 can push the movable plate 18 as a whole toward the fixed plate 15 through the wedge block 31. When the movable plate 18 drives the C-shaped tube 19 to move to the inclined plate 25, the guide column 22 installed on the outside of the C-shaped tube 19 will abut against the inclined plate 25. Under the guidance of the inclined plate 25, the guide column 22 can drive the C-shaped tube 19 as a whole to move toward the rectangular cover 4, so that the tube mouth of the C-shaped tube 19 can be inserted into the one-way liquid injection valve 13, so that the C-shaped tube 19 and the fixed tube 12 are connected to each other, so that the pigment can be injected into the fixed tube 12 through the C-shaped tube 19 later, so that the pigment is sprayed onto the wire roller 9 through the atomizing nozzle 14, so that the wire roller 9 can bring the pigment into the scratches on the surface of the impregnated paper, making the scratches more obvious, so that the second industrial camera 6 can more clearly capture and detect the wear state of the impregnated paper. After the rectangular cover 4 mounted on the timing belt 3 leaves the impregnated paper, the impregnated paper continues to move to the wiping strip 7, so that the wiping strip 7 can wipe off the excess pigment adhering to the surface of the impregnated paper, leaving only the pigment in the scratch of the impregnated paper, thereby forming a clear contrast between the scratch and the surrounding impregnated paper, so that the second industrial camera 6 can more clearly capture and inspect the scratch; In the initial stage of the movement of the C-shaped tube 19 driven by the movable plate 18, when the tube mouth of the C-shaped tube 19 is not fully inserted into the one-way liquid injection valve 13, the movable rod 33 and the sleeve 34 are arranged to offset the stroke of the liquid injection tube 26 in this section, thereby preventing the piston 32 from moving at this time, causing the pigment in the liquid injection tube 26 to be squeezed into the C-shaped tube 19, resulting in the dripping of pigment and contamination of the frame 1; After the end of the movable rod 33 abuts against the fixed plate 15, the mouth of the C-shaped tube 19 is fully inserted into the one-way liquid injection valve 13. As the liquid injection tube 26 continues to move, the piston 32 installed at the end of the movable rod 33 squeezes the pigment sucked from the liquid storage tank 28 into the C-shaped tube 19 through the first hose 29, and then injects the pigment into the fixed tube 12 through the C-shaped tube 19, thereby achieving the pigment filling effect. After the guide post 22 moves to the end of the pressure plate 24, the C-shaped tube 19 will pull out the one-way liquid injection valve 13 under the elastic force of the compression spring 21, completing the liquid injection operation. Subsequently, the oblique edge of the wedge block 31 will abut against the end of the strip-shaped opening opened in the frame 1, causing the wedge block 31 to press the second spring rod 30, causing the wedge block 31 to pass over the rectangular cover 4. Under the elastic force of the first spring rod 16, the movable plate 18 is pushed back to its original position, so that the next liquid injection operation of the fixed tube 12 can be carried out. When the movable plate 18 drives the injection tube 26 to reset, the piston 32 and the movable rod 33 will be pulled accordingly. After the retaining ring 35 and the limit ring installed on the inner wall of the sleeve 34 are at odds, the piston 32 stops moving, so that the piston 32 and the injection tube 26 move relative to each other, so that the piston 32 can suck the pigment in the liquid storage tank 28 into the injection tube 26 through the second hose 27, completing the automatic filling operation in the injection tube 26. The specific connection method and working principle of multiple electrical components are well known in the art and will not be elaborated here.

[0026] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
