Description

Technical Field

[0001] The present application relates to the technical field of coating equipment, and in particular to an energy-saving coating equipment and a method for using the same. Background Art

[0002] Coated fabric mainly refers to a layer of material with special functions coated on the basis of fabric using a special process, which adds special functions to the fabric, so it is also called functional coated fabric. Depending on the coating process, there are mercerized leather, matte, anti-leather and wrinkled leather, etc., which have functions such as waterproof, windproof and breathable.

[0003] Coating equipment is required when coating fabrics. The coating methods generally include rolling, spraying, and transfer, among which rolling is to coat the coating on a coating roller or fabric. When the fabric is being transported, the coating roller and the fabric are rolled and overlapped, and the coating roller evenly coats the coating on the fabric when rotating. Existing rolling coating equipment has certain shortcomings in use. Since the coating roller is in a continuous rotation state, after the coating roller applies the coating to the fabric, the coating roller will have residual coating all over the coating roller. After long-term coating, the residual coating will partially condense due to not being removed. The condensed coating will affect subsequent coating, resulting in uneven coating or scratches. At the same time, under the action of the rotating centrifugal force, the residual coating adhered to the side of the coating roller close to the output end of the fabric will splash on the coated fabric, resulting in excess paint spots on the evenly coated fabric, thereby affecting the coating effect of the fabric. At the same time, the coating width of the coating roller is not convenient to be adjusted accordingly according to the width of the fabric, making it inconvenient to use. Therefore, the present application proposes an energy-saving coating equipment and a method for using the same. Summary of the invention

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0021] like Figure 1-Figure 8 As shown, an energy-saving coating device proposed in one embodiment of the present application includes: A frame 1, on which two mounting frames 2 are symmetrically arranged, a coating roller 3 is rotatably arranged between the two mounting frames 2, one end of the coating roller 3 is connected to a motor 4 arranged on one of the mounting frames 2, preferably, the frame 1 includes a supporting plate, and two legs are arranged at the bottom of the supporting plate. When the cloth is coated, the cloth is attached to the top of the supporting plate during transmission, and the motor 4 works, and its output shaft drives the coating roller 3 to rotate, so that the outer surface of the coating roller 3 rolls and overlaps with the cloth; The material storage box 5 is arranged on the two mounting frames 2 and is located at the upper end of one side of the coating roller 3. The bottom of the material storage box 5 is constructed with a first arc-shaped recessed portion that is gap-matched with the circumferential surface of the coating roller 3. A seepage groove 6 is penetrated through the first arc-shaped recessed portion. The material storage box 5 is located on one side of the cloth input end. Paint is added into the material storage box 5, and the paint flows along the seepage groove 6. Since the bottom of the material storage box 5 is constructed with a first arc-shaped recessed portion, and the seepage groove 6 is opened on the first arc-shaped recessed portion, the paint will flow through the seepage groove 6 to the outer surface of the coating roller 3. When the coating roller 3 rotates, the paint is coated on the cloth. Preferably, it should be noted that the seepage groove 6 is opened along the length direction of the material storage box 5 and is relatively narrow. The paint has a certain viscosity. Therefore, when the seepage groove 6 is relatively narrow, and the paint is a fluid, it has fluidity, and the paint in the material storage box 5 will flow out from the seepage groove 6, thereby adhering to the surface of the coating roller 3; The collecting box 7 is arranged on the two mounting frames 2 and is located at the lower end of one side of the coating roller 3. The collecting box 7 is located on one side of the cloth output end. The top of the collecting box 7 is constructed with a second arc-shaped recessed portion that is gap-matched with the circumferential surface of the coating roller 3. A scraper 8 is arranged on the inner wall of one side of the collecting box 7. The end of the scraper 8 is in contact with and overlaps the circumferential surface of the coating roller 3. When the coating roller 3 rotates to coat the cloth, the paint remaining on the outer surface of the coating roller 3 will be scraped by the scraper 8, and the paint dropped by the scraping will fall into the collecting box 7, so that when the coating roller 3 rotates, the paint attached to the front half of the coating roller 3 is The front half of the coating roller 3 is the input end of the fabric, so even if the coating is splashed, it will not be affected. The rear half of the coating roller 3 will not have residual coating due to the scraping of the scraper 8, and will not be splashed onto the coated fabric due to the centrifugal force of rotation, thereby ensuring the coating quality. At the same time, only the front half of the coating roller 3 is coated with coating, but as it rotates, the scraper 8 scrapes it, thereby preventing the coating roller 3 from being adhered to and condensed for a long time due to not being scraped for a long time, avoiding the occurrence of uneven coating or scratches due to condensed coating, and reducing the scrap loss of fabric due to coating scratches. The material return mechanism 9 is arranged in the collecting box 7, and is used to return the collected paint to the material storage box 5. The paint intercepted by the scraper in the collecting box 7 can be returned to the material storage box 5 through the material return mechanism 9, so as to achieve the effect of recycling and reduce the waste of paint; The overall structure of the device is to load and coat the material from the front side of the coating roller 3. After coating, the surface is scraped and brushed by a scraper 8 to scrape off the residual coating, so that the back half of the coating roller 3 remains clean, and the adhered coating is prevented from being splashed onto the coated fabric again under the action of centrifugal force. At the same time, the outer surface of the coating roller 3 can be scraped and brushed to prevent the coating from adhering to its surface and causing condensation without being cleaned, thereby ensuring the coating effect.

[0022] like Figure 1 , Figure 6 and Figure 8 As shown, in some embodiments, the return mechanism 9 includes an arc plate 901, one end of the arc plate 901 is installed in the collection box 7 and is in clearance with the circumferential surface of the coating roller 3, an arc groove 902 is opened on one side of the arc plate 901, the arc groove 902 is connected to the collection box 7, and transmission rollers 903 are rotatably arranged at both ends of the arc groove 902, and transmission belts 904 are arranged on the two transmission rollers 903 for transmission and winding, and a sponge belt 905 is arranged on the outer transmission surface of the transmission belt 904, and a first pulley assembly 906 is connected between one of the transmission rollers 903 and the coating roller 3, and an extrusion piece 907 is arranged in the material storage box 5, and the extrusion piece 907 is used to move the sponge belt 90 5 is squeezed out and transported to the storage box 5. When the scraper 8 scrapes the excess paint and drops it into the collection box 7, under the linkage of the first pulley assembly 906, one of the transmission rollers 903 rotates synchronously with the coating roller 3, thereby driving the transmission belt 904 to transmit. Since the paint is a fluid, and the sponge belt 905 (the belt body made of sponge) has adsorption properties, when the transmission belt 904 is transmitting, the sponge belt 905 will absorb the paint, thereby driving the paint to be transmitted. After carrying the paint to the collection box 7, the adsorbed paint is squeezed out by the extrusion piece 907, so that the paint falls into the collection box 7, thereby achieving the effect of returning the material.

[0023] like Figure 6 As shown, in some embodiments, the extrusion member 907 includes a spring telescopic rod 9071 disposed in the material storage box 5, and a mounting plate 9072 is disposed at the free end of the spring telescopic rod 9071. A squeezing roller 9073 is rotatably disposed on the mounting plate 9072, and the squeezing roller 9073 rolls and overlaps with the sponge belt 905, as shown in FIG. Figure 6 As shown, the squeezing roller 9073 overlaps with the bottom side of one end of the sponge belt 905 located in the storage box 5. The sponge belt 905 becomes full after absorbing the paint. Under the elastic resistance of the spring telescopic rod 9071, the squeezing roller 9073 applies a certain squeezing force to the sponge belt 905. Under the action of the squeezing force, the absorbed paint can be squeezed out, and the paint falls into the storage box 5 under the action of gravity. The squeezing roller 9073 is rotated so that it rolls and overlaps with the sponge belt 905 to reduce friction resistance and ensure the smoothness of transmission of the sponge belt 905 and the conveyor belt 904.

[0024] like Figure 6 and Figure 8 As shown, in some embodiments, a plurality of guide rollers 10 are rotatably arranged in the arc groove 902, and the plurality of guide rollers 10 are divided into two rows and both rows are distributed in an arc array. Preferably, as shown in FIG. Figure 6 and Figure 8 As shown, since the sponge belt 905 is arranged on the outer transmission surface of the conveyor belt 904, and the guide rollers 10 are divided into two rows, one row of guide rollers 10 rolls and overlaps with the inner transmission surface of the conveyor belt 904, and the other row of guide rollers 10 rolls and overlaps with the sponge belt 905. Through the arrangement of the guide rollers 10, the opposite sides of the inner wall of the conveyor belt 904 will not overlap, and the sponge belt 905 will not overlap with the inner wall of the arc groove 902, so as to reduce friction resistance, make the transmission smoother, and thus improve practicality.

[0025] like Figure 5 As shown, in some embodiments, a plurality of slide bars 11 are slidably penetrated in an array of inner walls on one side of the collecting box 7, and a scraper 8 is arranged at one end of the plurality of slide bars 11. A resistance spring 12 sleeved on the slide bar 11 is installed between the scraper 8 and the inner wall of the collecting box 7. Since the scraper 8 is in contact with the coating roller 3, the scraper 8 will be worn to a certain extent after long-term use under the action of the resistance friction force, thereby causing a gap between the scraper 8 and the coating roller 3. Through the elastic resistance of the resistance spring 12, the scraper 8 can automatically fill the gap caused by wear after long-term scraping and brushing. When the scraper 8 is completely worn and cannot be used, it can be replaced without the need for the staff to make real-time adjustments according to the wear condition, thereby improving the coating efficiency.

[0026] like Figure 4 and Figure 7 As shown, in some embodiments, slide grooves 13 are provided on opposite sides of the inner wall of the seepage groove 6, and two sealing plates 14 are slidably arranged in the two slide grooves 13. The opposite ends of the two sealing plates 14 slide through the two ends of the storage box 5 respectively. When coating the cloth, due to the different widths of the cloth, the width of the coating is also different. The spacing between the two sealing plates 14 is the coating width. By sliding and adjusting the two sealing plates 14, the length of the seepage groove 6 can be adjusted, thereby changing the seepage length of the coating, thereby achieving the effect of adjusting the coating width, so as to be suitable for coatings of cloths of different widths, thereby improving practicality.

[0027] like Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, a bidirectional screw rod 15 is rotatably provided on the two mounting frames 2, and both ends of the bidirectional screw rod 15 are threadedly sleeved with a partition 16, and the two partitions 16 are respectively fixedly connected to the opposite ends of the two sealing plates 14. Preferably, one side of the partition 16 overlaps with the surface of the coating roller 3, and the bottom side thereof overlaps with the supporting plate. When the cloth is placed on the supporting plate, the bidirectional screw rod 15 is rotated by twisting. Under the action of the bidirectional thread, the two partitions 16 are adjusted to be close to each other, so that the two partitions 16 overlap with the two sides of the cloth respectively, so that the coating width of the seepage groove 6 can be quickly adjusted to make the coating width adapt to the cloth width. At the same time, during the coating process, a small amount of coating will flow along the surface of the cloth due to the rolling of the coating roller 3, and part of the coating will flow along the two sides of the cloth. The partition 16 is blocked to prevent the coating from flowing out of the cloth surface to both sides, thereby improving practicality.

[0028] like Figure 2 As shown, in some embodiments, a connecting frame 17 is provided on the two mounting frames 2, a reciprocating screw 18 is rotatably provided on the connecting frame 17, a second pulley assembly 19 is connected between the reciprocating screw 18 and the coating roller 3, a movable block 20 is movably sleeved on the reciprocating screw 18, a conveying pipe 21 is provided on the movable block 20, preferably, the conveying pipe 21 comprises a hard pipe arranged on the movable block 20, a hose is connected to the hard pipe, in actual use, the hose is connected to an external feeding device, because the cloth has a long length, therefore, it is necessary to continuously feed the material storage box 5, when the coating roller 3 rotates, under the linkage of the second pulley assembly 19, the reciprocating screw 18 drives the movable block 20 to move back and forth, so that the conveying pipe 21 continuously feeds the material into the material storage box 5 under the action of the external feeding device, and the feeding is horizontally moved during the feeding process to ensure the stability of the feeding.

[0029] like Figure 1 and Figure 3As shown, in some embodiments, two smoothing rollers 22 distributed up and down are rotatably arranged on the two mounting frames 2, and spiral strips 23 are respectively arranged at both ends of the smoothing roller 22. Preferably, the two spiral strips 23 on the same smoothing roller 22 rotate in opposite directions, and the two spiral strips 23 opposite to each other on the two smoothing rollers 22 rotate in opposite directions. Gears 24 are fixed on the two smoothing rollers 22, and the teeth of the two gears 24 are meshed. A third pulley assembly 25 is connected between one of the smoothing rollers 22 and the coating roller 3. Under the linkage of the third pulley assembly 25 and the two Under the meshing of the teeth of the gear 24, the two smoothing rollers 22 rotate synchronously in opposite directions. The cloth will be subjected to stress during transmission, and some softer cloth will produce wrinkles under stress. The smoothing rollers 22 are set, and when the two smoothing rollers 22 rotate synchronously in opposite directions, it will not only assist the cloth transmission, but also, under the action of the spiral strips 23, it will have a wrinkle-removing effect on the cloth, so that the cloth is in a flat state when passing through the coating roller 3, which not only ensures the coating effect, but also facilitates the partition 16 to effectively overlap the side of the cloth to ensure the coating effect on the side of the cloth.

[0030] like Figure 1-Figure 8 As shown, in some embodiments, a method for using an energy-saving coating device comprises the following steps: S1: When the fabric is being transported, it first moves through two smoothing rollers 22 and is placed under the coating roller 3. The two smoothing rollers 22 rotate synchronously in opposite directions to smooth and remove wrinkles from the fabric. S2: Twist the bidirectional screw rod 15 to rotate, driving the two partitions 16 to overlap the two ends of the cloth respectively, and at the same time the two sealing plates 14 partially block the seepage groove 6, so that the width of the seepage groove 6 is adapted to the width of the cloth; S3: Adding paint into the material storage box 5, the paint flows along the seepage groove 6 on the outer surface of the coating roller 3, and as the coating roller 3 rotates, the paint flowing on the surface is coated on the surface of the cloth; S4: When the coating roller 3 is coating the cloth, the scraper 8 scrapes the surface of the coating roller 3 to ensure that no coating remains on the side of the coating roller 3 at the cloth output end, and the scraped coating is stored in the collection box 7; S5: As the coating roller 3 rotates, the conveyor belt 904 drives the sponge belt 905 to transmit synchronously. The sponge belt 905 absorbs the paint in the collecting box 7 and is squeezed and retained in the storage box 5 by the extrusion member 907 when it is transmitted to the top of the storage box 5, thereby forming a recycling process.

A method for using an energy-saving coating device, characterized in that: Using an energy-saving coating device as described in any one of claims 1 to 9, the following steps are performed: S1: When the cloth is being transported, it first moves through two smoothing rollers (22) and is placed under the coating roller (3), and the two smoothing rollers (22) rotate synchronously in opposite directions to smooth and remove wrinkles from the cloth; S2: twisting the bidirectional screw rod (15) to rotate, driving the two partition plates (16) to overlap the two ends of the cloth respectively, and at the same time the two sealing plates (14) partially block the seepage groove (6), so that the width of the seepage groove (6) is adapted to the width of the cloth; S3: adding paint into the material storage box (5), and the paint flows along the seepage groove (6) onto the outer surface of the coating roller (3), and as the coating roller (3) rotates, the paint flowing on the surface is coated on the surface of the cloth; S4: When the coating roller (3) is coating the fabric, the scraper (8) scrapes the surface of the coating roller (3) to ensure that no coating remains on the side of the coating roller (3) at the fabric output end, and the scraped coating is stored in the collection box (7); S5: As the coating roller (3) rotates, the conveyor belt (904) drives the sponge belt (905) to transmit synchronously. The sponge belt (905) absorbs the coating in the collection box (7) and squeezes the coating through the extrusion member (907) to be stored in the storage box (5) when it is transmitted to the top of the storage box (5), thereby realizing recycling.
