Description

Technical Field

[0001] This invention relates to the field of coating equipment technology, specifically a floor coating equipment that prevents edge glue overflow. Background Technology

[0002] When flooring is processed, the surface needs to be coated, so coating equipment such as a two-roller glue applicator is required.

[0003] When using a two-roller coating machine to coat floors, some floors require multiple coats of different paints. After the first coat is applied, the floor needs to be transferred to the station for the second coat. During this transfer, dust may fall onto the floor surface, necessitating cleaning before the next coat. However, since the primer may be thin, cleaning can scratch it, affecting the quality of subsequent coats. Therefore, a cleaning mechanism to prevent damage to the primer is required. Furthermore, various factors can cause changes in the roller speed during floor coating, such as machine stoppage and restart. Thicker paint can increase the roller load, causing a decrease in roller speed, which may result in incomplete paint application to the floor surface, thus affecting the coating quality. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to prevent scratches on the floor surface during cleaning and to prevent glue leakage on the floor surface due to a decrease in the speed of the glue roller, which affects the quality of coating. The present invention provides a floor coating device that prevents glue overflow at the edges.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A floor coating equipment for preventing edge glue overflow, the coating equipment includes a conveying device, a glue application mechanism and a paint conveying mechanism on the conveying device, a glue overflow prevention mechanism on the glue application mechanism, a dust removal mechanism on one side of the conveying device, and a height adjustment mechanism on the conveying device. The glue application mechanism includes a mounting plate, a steel roller, a glue roller, and a mounting base. The mounting plate and the glue roller are rotatably connected, the mounting plate and the mounting base are slidably connected, and the mounting base and the steel roller are rotatably connected. The mounting plate is equipped with a roller gap adjustment mechanism and a power source. The two output ends of the power source are respectively connected to the steel roller and the glue roller for transmission. The roller gap adjustment mechanism includes an adjustment block and a drive unit. The mounting base is equipped with an electric cylinder output end, and the electric cylinder fixed end is located on the adjustment block. The height adjustment mechanism is driven to the mounting plate, the adjustment block is slidably connected to the mounting plate, a return spring is provided between the adjustment block and the mounting plate, and the drive unit is slidably connected to the rubber roller.

[0006] The conveying device is a conveyor belt. Workers place the flooring to be coated onto the conveyor belt, which then transports the flooring in the coating direction. A dust removal mechanism removes dust and other impurities from the flooring surface to prevent them from affecting the coating effect. The power source is an electric motor. Steel rollers and rubber rollers are connected to the output ends of two motors via flanges. Based on preset parameters, such as the coating thickness, workers adjust the motor speed through the control system, thereby adjusting the speed of the steel and rubber rollers. A height adjustment mechanism and mounting plate are connected for transmission. The steel roller's mounting base is connected to the mounting plate via a guide rail slider, and the rubber roller is rotatably connected to the mounting plate via bearings. The height adjustment mechanism drives the mounting plate to move up and down, thus adjusting the distance between the steel and rubber rollers and the flooring, thereby controlling the coating process. The thickness of the adhesive coating is adjusted by an electric cylinder mounted on an adjusting block via a roller gap adjustment mechanism. The output of the electric cylinder pushes the mounting base to slide on the guide rail, thereby actively adjusting the gap between the steel roller and the rubber roller. When the rubber roller speed is lower than the preset value, the drive unit can also push the adjusting block to slide according to the decrease in speed. A return spring is provided between the adjusting block and the mounting plate, which can reset when the rubber roller speed recovers, thereby dynamically adjusting the gap between the steel roller and the rubber roller. This ensures that the coating is applied to the floor in a preset amount, preventing the coating from becoming too small and accumulating on the steel roller, rubber roller, and floor, causing the coating to overflow from the edges. At the same time, an anti-overflow mechanism is set to prevent the coating from overflowing from the edges of the floor. After the coating is completed, the floor is conveyed to the next process via a conveyor belt.

[0007] Furthermore, the drive unit includes a drive block, an adjusting block with a fixing block, a drive block and a rubber roller in a sliding connection, an adjusting spring between the drive block and the mounting plate, a drive block with an inclined surface, a fixing block and the inclined surface of the drive block abutting each other, and a control component on the rubber roller abutting each other with the drive block.

[0008] When the glue is applied, the glue roller rotates, causing the control component to push the drive block to slide along the glue roller axis. This prevents the inclined surface on the drive block from blocking the fixed block on the adjusting block, allowing the adjusting block to slide under the action of the return spring, thus adjusting the gap between the glue roller and the steel roller. When the glue roller speed decreases, the drive block returns to its original position under the action of the adjusting spring, causing the inclined surface of the drive block to push the fixed block, thereby driving the adjusting block to slide.

[0009] Furthermore, the control assembly includes a control block, a fixed frame on the rubber roller, the fixed frame and the control block being slidably connected, and a preload spring being provided between the fixed frame and the control block; The drive block has a tapered groove, which abuts against the control block.

[0010] The fixed frame installed on the rubber roller rotates with the rubber roller, causing the control block to slide along the groove of the fixed frame under the action of centrifugal force, overcoming the elastic force of the pre-tightening spring. The drive block is provided with a conical groove, and the conical surface of the conical groove abuts against the control block, thereby causing the control block to push the drive block to slide along the axis of the rubber roller. When the speed of the rubber roller decreases, the drive block is reset under the action of the adjusting spring, and the control block is reset under the push of the drive block.

[0011] Furthermore, the height adjustment mechanism includes a handwheel and a transmission screw. The handwheel is rotatably connected to the transmission screw and the conveying device, the handwheel and the transmission screw are drive-connected, the mounting plate and the transmission screw are drive-connected, and the mounting plate and the conveying device are slidably connected.

[0012] By setting a handwheel, one end of which is connected to a bevel gear and a transmission screw, turning the handwheel can drive the transmission screw to rotate. The mounting plate and the frame of the conveying device are slidably connected by a guide rail slider. The mounting plate is connected to the transmission screw by a nut. When the handwheel is turned, the mounting plate moves vertically along the axis of the transmission screw, thereby adjusting the gap between the glue roller and the floor, and thus adjusting the thickness of the glue coating.

[0013] Furthermore, the anti-overflow adhesive mechanism includes two adhesive baffles and a connecting rod, which are slidably connected. A connecting spring is sleeved on the connecting rod, and the two ends of the connecting spring are respectively installed on the two adhesive baffles. The connecting rod and the conveying device are slidably connected, and a retaining spring is provided between the connecting rod and the conveying device.

[0014] By setting two baffles, the edges of the floorboards are blocked during adhesive application, preventing adhesive from overflowing from the edges. The two baffles are slidably connected by a connecting rod. Under the action of a connecting spring, the two baffles exert a force that brings them closer together, thus keeping the baffles tightly against the edges of the floorboards and preventing adhesive spillage. At the same time, a slope is set on one side of the baffles, allowing the floorboards to slide between the two baffles, making it adjustable according to the width of the floorboards. The connecting rod is slidably connected to the frame of the conveying device, and a retaining spring is set between the connecting rod and the conveying device to ensure that the baffles are always tightly against the glue roller and steel roller, so that no gaps appear between the baffles and the glue roller when the height of the glue roller and steel roller is adjusted, preventing adhesive leakage.

[0015] Furthermore, the baffle plate is provided with an elastic block and an adjusting plate. The elastic block is provided with an adjusting groove. The adjusting plate and the adjusting groove are slidably connected. An elastic element is provided between the adjusting plate and the adjusting groove.

[0016] An elastic block made of elastic material is placed above the baffle plate. Gas at a certain pressure is injected into the adjustment groove of the elastic block. The adjustment groove is divided into two parts by the adjustment plate. When the gap between the rubber roller and the steel roller decreases, the rubber roller and the steel roller squeeze the elastic block, causing the gas to push the adjustment plate to slide into the adjustment groove against the elastic force of the elastic element. This ensures that the baffle plate always fits the rubber roller and the steel roller, preventing edge glue overflow.

[0017] Furthermore, the paint conveying mechanism includes a material box, and the material box outlet is equipped with a regulating valve, which is equipped with a discharge pipe.

[0018] By setting up a material bin, the paint is conveyed to the discharge pipe through the built-in conveying pump in the material bin. The paint is then conveyed to the coating mechanism through the outlet of the discharge pipe between the steel roller and the rubber roller. By setting a regulating valve at the outlet of the material bin, the instantaneous amount of paint conveyed is controlled to avoid excessive paint conveying and glue overflow.

[0019] Furthermore, the dust removal mechanism includes a dust removal hood and a cleaning roller. The dust removal hood is equipped with a collection box and a fan. The dust removal hood and the cleaning roller are rotatably connected. The dust removal hood is equipped with a drive motor, and the output end of the drive motor is connected to the cleaning roller via a transmission.

[0020] By setting up a fan, negative pressure is generated in the adsorption tank inside the dust removal hood to clean dust and other impurities from the floor surface. The adsorption tank is connected to the inlet of the collection box, and the air outlet at the other end of the collection box is connected to the fan through a pipe, so that the dust is collected through the collection box to avoid polluting the working environment. By setting up a drive motor, which is connected to the cleaning roller through a synchronous belt, the drive motor drives the cleaning roller to rotate, and the brush of the cleaning roller sweeps the ground, so that the dust adsorbed on the floor can be swept off the floor surface and adsorbed through the adsorption tank, improving the cleaning effect and ensuring the quality of coating.

[0021] Furthermore, a cam is provided at the output end of the drive motor; The conveying device is equipped with a mounting frame and a vibration spring. One end of the vibration spring is equipped with a vibration block. The mounting frame and the vibration block are slidably connected, and the cam and the vibration block abut against each other.

[0022] A transmission belt is set at the output end of the drive motor, and a cam is installed on the transmission belt pulley, so that the drive motor can drive the cam to rotate. This causes the cam to periodically push the vibrating block to slide along the mounting frame and collide with the support block of the conveying device, thereby causing the conveyor belt to vibrate. By setting a vibration spring, the vibrating block is reset, so that it can periodically collide with the support block when the cam rotates.

[0023] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a roller gap adjustment mechanism, the distance between the rubber roller and the steel roller is dynamically adjusted when the speed of the rubber roller changes during coating, so that the floor surface can be completely coated with glue, avoiding local missing glue, thereby ensuring the quality of coating.

[0024] 2. By setting up an anti-overflow glue mechanism, the glue baffle can adapt to boards of different widths and is not affected by the adjustment of the distance between the glue roller and the floor. This prevents glue from overflowing at the edges of the floor during coating, thereby ensuring the quality of the coating.

[0025] 3. By setting up a dust removal mechanism, the dust and other impurities on the floor surface to be coated are cleaned before coating, thereby ensuring the quality of subsequent coating. Attached Figure Description

[0028] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: As Figures 1-5 As shown, the present invention provides a technical solution: a floor coating equipment for preventing edge glue overflow. The coating equipment includes a conveying device 1, a glue application mechanism 2 and a paint conveying mechanism 6 on the conveying device 1, an anti-glue overflow mechanism 3 on the glue application mechanism 2, a dust removal mechanism 4 on one side of the conveying device 1, and a height adjustment mechanism 5 on the conveying device 1. The glue application mechanism 2 includes a mounting plate 21, a steel roller 22, a glue roller 23, and a mounting base 25. The mounting plate 21 and the glue roller 23 are rotatably connected, the mounting plate 21 and the mounting base 25 are slidably connected, and the mounting base 25 and the steel roller 22 are rotatably connected. The mounting plate 21 is provided with a roller gap adjustment mechanism 24 and a power source 26. The two output ends of the power source 26 are respectively connected to the steel roller 22 and the glue roller 23 for transmission. The roller gap adjustment mechanism 24 includes an adjustment block 241 and a drive unit 242. The mounting base 25 is provided with an output end of an electric cylinder 243, and the fixed end of the electric cylinder 243 is located on the adjustment block 241. The height adjustment mechanism 5 is connected to the mounting plate 21 via a transmission, the adjustment block 241 is slidably connected to the mounting plate 21, a return spring 244 is provided between the adjustment block 241 and the mounting plate 21, and the drive unit 242 is slidably connected to the rubber roller 23.

[0030] The conveying device 1 is a conveyor belt. Workers place the flooring to be coated onto the conveyor belt, which then transports the flooring in the coating direction. A dust removal mechanism 4 removes dust and other impurities from the flooring surface to prevent them from affecting the coating effect. The power source 26 is a motor. Steel roller 22 and rubber roller 23 are respectively connected to the output ends of two motors via flanges. Based on preset parameters, such as the coating thickness, workers adjust the motor speed through the control system, thereby adjusting the speed of steel roller 22 and rubber roller 23. These are connected via a height adjustment mechanism 5 and a mounting plate 21. The mounting base 25 of steel roller 22 is connected to the mounting plate 21 via a guide rail slider. Rubber roller 23 is rotatably connected to the mounting plate 21 via bearings. The height adjustment mechanism 5 drives the mounting plate 21 to move up and down, thereby adjusting the distance between steel roller 22 and rubber roller 23 and the flooring, thus controlling the coating thickness. The electric cylinder 243, mounted on the adjusting block 241 via the roller gap adjusting mechanism 24, allows the output end of the electric cylinder 243 to push the mounting base 25 to slide on the guide rail, thereby actively adjusting the gap between the steel roller 22 and the rubber roller 23. When the speed of the rubber roller 23 is lower than the preset value, the drive unit 242 can also push the adjusting block 241 to slide according to the decrease in speed. A reset spring 244 is provided between the adjusting block 241 and the mounting plate 21, which can reset when the speed of the rubber roller 23 recovers, thereby dynamically adjusting the gap between the steel roller 22 and the rubber roller 23, so that the paint can be applied to the floor in a preset amount, avoiding paint accumulation on the steel roller 22, rubber roller 23 and the floor due to insufficient paint application, which would cause paint to overflow from the edges. At the same time, the anti-overflow mechanism 3 is provided to prevent the paint from overflowing from the edges of both sides of the floor. After the paint application is completed, the floor is conveyed to the next process via a conveyor belt.

[0031] like Figures 3-5 As shown, the drive unit 242 includes a drive block 2421, a fixing block 2422 on the adjusting block 241, the drive block 2421 and the rubber roller 23 are slidably connected, an adjusting spring 2424 is provided between the drive block 2421 and the mounting plate 21, the drive block 2421 is provided with an inclined surface, the fixing block 2422 and the inclined surface of the drive block 2421 abut against each other, and a control component 2423 is provided on the rubber roller 23, the control component 2423 abuts against the drive block 2421.

[0032] When the glue application begins, the glue roller 23 rotates, causing the control component 2423 to push the drive block 2421 to slide along the axis of the glue roller 23. This causes the inclined surface on the drive block 2421 to no longer block the fixed block 2422 on the adjusting block 241, allowing the adjusting block 241 to slide under the action of the return spring 244, thus adjusting the gap between the glue roller 23 and the steel roller 22. When the speed of the glue roller 23 decreases, the drive block 2421 returns to its original position under the action of the adjusting spring 2424, causing the inclined surface of the drive block 2421 to push the fixed block 2422, thereby causing the adjusting block 241 to slide.

[0033] like Figure 5As shown, the control component 2423 includes a control block 24231, a fixing frame 24232 is provided on the rubber roller 23, the fixing frame 24232 and the control block 24231 are slidably connected, and a pre-tensioning spring 24233 is provided between the fixing frame 24232 and the control block 24231. The drive block 2421 is provided with a tapered groove 24211, which abuts against the control block 24231.

[0034] The fixed frame 24232 installed on the rubber roller 23 rotates with the rubber roller 23, thereby causing the control block 24231 to slide along the groove of the fixed frame 24232 under the action of centrifugal force, overcoming the elastic force of the pre-tightening spring 24233. The drive block 24211 is provided with a conical groove 24211, and the conical surface of the conical groove 24211 abuts against the control block 24231, thereby causing the control block 24231 to push the drive block 2421 to slide along the axis of the rubber roller 23. When the rotation speed of the rubber roller 23 decreases, the drive block 2421 is reset under the action of the adjusting spring 2424, and the control block 24231 is reset under the push of the drive block 2421.

[0035] like Figure 1 and Figure 2 As shown, the height adjustment mechanism 5 includes a handwheel 51 and a transmission screw 52. Both the handwheel 51 and the transmission screw 52 are rotatably connected to the conveying device 1. The handwheel 51 and the transmission screw 52 are drive-connected. The mounting plate 21 and the transmission screw 52 are drive-connected. The mounting plate 21 and the conveying device 1 are slidably connected.

[0036] By setting a handwheel 51, one end of the handwheel 51 is connected to the transmission screw 52 via a bevel gear, so that rotating the handwheel 51 can drive the transmission screw 52 to rotate. The mounting plate 21 and the frame of the conveying device 1 are slidably connected by a guide rail slider. The mounting plate 21 is connected to the transmission screw 52 via a nut. When the handwheel 51 is rotated, the mounting plate 21 moves vertically along the axis of the transmission screw 52, ​​thereby adjusting the gap between the glue roller 23 and the floor, and thus adjusting the thickness of the glue coating.

[0037] like Figures 6-8 As shown, the anti-overflow adhesive mechanism 3 includes two adhesive baffles 31 and a connecting rod 32. The two adhesive baffles 31 and the connecting rod 32 are slidably connected. A connecting spring 33 is sleeved on the connecting rod 32. The two ends of the connecting spring 33 are respectively installed on the two adhesive baffles 31. The connecting rod 32 and the conveying device 1 are slidably connected, and a retaining spring 34 is provided between the connecting rod 32 and the conveying device 1.

[0038] By setting two baffle plates 31, the edges of the floor are blocked during glue application, thus preventing glue from overflowing from the edges of the floor. The two baffle plates 31 are slidably connected by a connecting rod 32. Under the action of the connecting spring 33, the two baffle plates 31 generate a force that brings them closer together, so that the baffle plates 31 are pressed tightly against the edges of the floor to prevent glue overflow. At the same time, a slope is set on one side of the baffle plate 31, so that the floor can slide between the two baffle plates 31 through the slope, and the spacing between the baffle plates can be adjusted according to the width of the floor. The connecting rod 32 is slidably connected to the frame of the conveying device 1, and a pressing spring 34 is set between the connecting rod 32 and the conveying device 1, so that the baffle plate 31 is always pressed tightly against the glue roller 23 and the steel roller 22, so that when the height of the glue roller 23 and the steel roller 22 is adjusted, the baffle plate 31 will not have gaps that would cause glue leakage.

[0039] like Figure 8 As shown, the baffle plate 31 is provided with an elastic block 311 and an adjusting plate 312. The elastic block 311 is provided with an adjusting groove 3111. The adjusting plate 312 and the adjusting groove 3111 are slidably connected. An elastic element 313 is provided between the adjusting plate 312 and the adjusting groove 3111.

[0040] An elastic block 311, made of elastic material, is located above the glue baffle 31. Gas of a certain pressure is injected into the adjustment groove 3111 of the elastic block 311. The adjustment groove 3111 is divided into two parts by the adjustment plate 312. When the gap between the rubber roller 23 and the steel roller 22 decreases, the rubber roller 23 and the steel roller 22 squeeze the elastic block 311, causing the gas to push the adjustment plate 312 to slide into the adjustment groove 3111 against the elastic force of the elastic element 313. This ensures that the glue baffle 31 always fits the rubber roller 23 and the steel roller 22, preventing edge glue overflow.

[0041] like Figure 1 As shown, the paint conveying mechanism 6 includes a material box 61, an adjusting valve 62 is provided at the outlet of the material box 61, and a discharge pipe 63 is provided on the adjusting valve 62.

[0042] By setting up a material box 61, the coating material is conveyed to the discharge pipe 63 by the built-in conveying pump of the material box 61. The coating material is then conveyed to the coating mechanism 2 through the outlet of the discharge pipe 63 towards the space between the steel roller 22 and the glue roller 23. By setting a regulating valve 62 at the outlet of the material box 61, the instantaneous amount of coating material is controlled to avoid excessive coating material conveying and glue overflow.

[0043] like Figure 9 As shown, the dust removal mechanism 4 includes a dust removal hood 41 and a cleaning roller 44. The dust removal hood 41 is provided with a collection box 42 and a fan 43. The dust removal hood 41 and the cleaning roller 44 are rotatably connected. The dust removal hood 41 is provided with a drive motor 45, and the output end of the drive motor 45 is connected to the cleaning roller 44 in a transmission connection.

[0044] By setting up a fan 43, a negative pressure is generated in the adsorption tank inside the dust removal hood 41 to clean dust and other impurities on the floor surface. The adsorption tank is connected to the inlet of the collection box 42, and the air outlet at the other end of the collection box 42 is connected to the fan 43 through a pipe, so that the dust is collected through the collection box 42 to avoid polluting the working environment. By setting up a drive motor 45, the drive motor 45 is connected to the cleaning roller 44 through a synchronous belt, so that the drive motor 45 drives the cleaning roller 44 to rotate, and the brush of the cleaning roller 44 sweeps the ground, so that the dust adsorbed on the floor can be swept off the floor surface and adsorbed through the adsorption tank, improving the cleaning effect and ensuring the quality of coating.

[0045] Example 2, as Figure 10 As shown, an auxiliary cleaning structure different from Embodiment 1 is provided. The difference is that this embodiment uses vibration to loosen dust and other impurities stuck in the floor by generating vibration on the conveying device 1, so that it does not need to directly contact the floor and avoids scratching the floor's primer.

[0046] The output end of the drive motor 45 is equipped with a cam 46; The conveying device 1 is equipped with a mounting frame 47 and a vibration spring 49. One end of the vibration spring 49 is equipped with a vibration block 48. The mounting frame 47 and the vibration block 48 are slidably connected, and the cam 46 abuts against the vibration block 48.

[0047] A transmission belt is set at the output end of the drive motor 45, and the cam 46 is mounted on the transmission belt pulley, so that the drive motor 45 can drive the cam 46 to rotate, thereby causing the cam 46 to periodically push the vibrating block 48 to slide along the mounting frame 47 and collide with the support block of the conveying device 1, thereby causing the conveyor belt to vibrate. By setting the vibration spring 49, the vibrating block 48 is reset, so that it can periodically collide with the support block when the cam 46 rotates.

[0048] The working principle of this invention is as follows: By rotating the handwheel 51, the gap between the rubber roller 23 and the floor is adjusted, thereby adjusting the thickness of the adhesive coating. The electric cylinder 243 pushes the mounting base 25 to slide on the guide rail, thus adjusting the gap between the steel roller 22 and the rubber roller 23. The worker places the floor to be coated onto the conveying device 1, causing the floor to be conveyed in the coating direction. The dust removal mechanism 4 removes dust from the floor surface to ensure coating quality. When the floor is conveyed to the coating position, a slope is set on one side of the adhesive baffle 31, allowing the floor to slide between the two baffles 31. Under the action of the connecting spring 33, the adhesive baffle 31 and the edge of the floor are made to fit together. Under the action of the clamping spring 34, the glue baffle 31 is pressed against the steel roller 22 and the glue roller 23 to prevent glue overflow. The paint is delivered to the discharge pipe 63 by the conveying pump built into the material box 61, so that the paint is delivered to the glue roller 23 and the steel roller 22. The steel roller 22 and the glue roller 23 are driven to rotate by the power source 26 to coat the floor. When the speed of the glue roller 23 decreases, the drive block 2421 is reset under the action of the adjusting spring 2424. The control block 24231 is reset under the push of the drive block 2421, so that the inclined surface of the drive block 2421 pushes the fixed block 2422, thereby driving the adjusting block 241 to slide, thereby reducing the roller gap and ensuring the glue coating effect.
