Description

Technical Field

[0001] This invention belongs to the field of board cleaning technology, specifically relating to a multi-faceted board cleaning device and process. Background Technology

[0002] The production of wood composite boards follows the process of cutting, drilling, edge banding, cleaning, and packaging. After cutting and drilling, some sawdust and dust remain on the surface of the wood composite boards. Then, the edge banding process is carried out, which leaves excess hot melt adhesive left on the side of the edge banding machine. Therefore, the wood composite boards need to be cleaned before packaging and shipping.

[0003] In the invention patent with application number "202010992618.6" and patent title "A Glue Removal Machine", the door panel to be treated is placed in the glue removal space inside the opening of the outer casing; one end of the door panel to be treated contacts multiple sets of conveyor rollers, and multiple sets of second telescopic devices drive the mounting plate to move towards the door panel to be treated so that the door panel is squeezed by multiple sets of elastic extrusion components; multiple sets of first telescopic devices drive two sets of mounting frames to move closer to each other so that multiple sets of glue removal rollers press against the end face of the door panel to be treated; two sets of first telescopic devices drive two sets of mounting frames to move closer to each other so that multiple sets of glue removal rollers press against the end face of the door panel to be treated; two sets of first telescopic devices drive two sets of mounting frames to move closer to each other so that multiple sets of glue removal rollers press against the end face of the door panel to be treated; The actuator drives multiple sets of adhesive removal rollers to rotate, while the drive assembly moves the pressed door panel back and forth directly between the rollers. The cleaning components on the outer circumference of the rotating rollers interact with the end face of the door panel to remove residual adhesive. After the adhesive removal is completed, the door panel can be removed from the opening. The debris raised during the adhesive removal process is collected into the dust collection assembly, replacing manual removal of residual adhesive from the end face of the door panel, greatly improving the efficiency of adhesive removal and the quality of adhesive removal.

[0004] The aforementioned patents can only clean the two opposite sides of the board, and cannot clean the sides of the board. Therefore, they cannot completely remove the adhesive residue on the board surface, resulting in poor adhesive removal effect. Summary of the Invention

DETAILED DESCRIPTION

[0047] The present application will be further described in conjunction with the embodiments shown in the accompanying drawings.

[0048] The plate multi-surface cleaning device of the present application comprises a stacking assembly 1, a first cleaning assembly 2 and a second cleaning assembly 3, and is usually used in the field of plate cleaning, and can complete the cleaning of the upper and lower surfaces and the side edges of the plate, with higher cleaning efficiency and better cleaning effect.

[0049] As shown in Figure 1 , 2 Fig. 1 is a structural schematic view of the stacking assembly 1, which has two groups, one of which is arranged on one side of the first cleaning assembly 2 and used for placing the plates one by one on the conveying roller 101, and the other group of the stacking assembly 1 is arranged on the other side of the second cleaning assembly 3 and used for collecting the cleaned plates one by one.

[0050] Each stack assembly 1 includes a conveying roller 101, a stack plate 102, a stack sprocket 103, a stack chain 104, a lug 105, a receiving plate 106 and a baffle plate 107. The conveying roller 101 is rotatably mounted on the conveying machine table through a bearing seat, and is used to convey the plate to be cleaned to the first cleaning assembly 2 and the second cleaning assembly 3. The material of the conveying roller 101 is rubber, which can avoid scratching the surface of the plate when conveying the plate.

[0051] The stack plate 102 is fixed on the conveying machine table and located on both sides of the conveying roller 101. The stack sprocket 103 is rotatably mounted on the inner side of the two stack plates 102. The stack chain 104 is arranged on the stack sprocket 103 in the vertical direction. The stack chain 104 is driven to rotate in the vertical direction by the rotation of the stack sprocket 103.

[0052] The lugs 105 are equidistantly fixed on the stack chain 104. The receiving plate 106 is horizontally fixed on the lug 105. The baffle plate 107 is fixed on the receiving plate 106 and perpendicular to the receiving plate 106. As shown in Figure 2 , the plate is placed between the two sets of receiving plates 106 arranged oppositely. When the stack chain 104 rotates in the vertical direction, the plate gradually moves downward to approach the conveying roller 101.

[0053] As shown in Figure 2 , the adjacent two sets of receiving plates 106 in the vertical direction are provided with a placing area. The plate is in the placing area. With the rotation of the stack chain 104, the plate is placed on the conveying roller 101 below. Under the rotation of the conveying roller 101, the plate is conveyed to the first cleaning assembly 2. Thus, the plate is conveyed piece by piece. When the plate is cleaned, the receiving plate 106 is driven to rise by the chain rising in the vertical direction, so as to collect the plate piece by piece.

[0054] As shown in Figure 3 , 4 , it is a structural schematic view of the first cleaning assembly 2. The first cleaning assembly 2 is located on one side of one of the stack assemblies 1, and is used to clean the upper surface and the lower surface of the plate at the same time. The first cleaning assembly 2 includes a material stirring mechanism, a squeezing mechanism, a main cleaning mechanism and a pushing mechanism. As shown in Figure 7 , the material stirring mechanism includes a gantry 201, a plate stirring shaft 202, a stirring wheel 203 and a protruding tooth 204. The gantry 201 is erected above the conveying roller 101. The gantry 201 is in the shape of “[”, and the opening of the “[” shaped gantry 201 faces downward, which facilitates the installation of the stirring wheel 203.

[0055] The dial plate shaft 202 is rotatably installed on the gantry 201 through a bearing and is located above the conveying roller 101. The dial wheel 203 has multiple groups and is sleeved on the dial plate shaft 202 at intervals and rotates synchronously with the dial plate shaft 202. The protruding teeth 204 are integrally arranged on the outer circumferential surface of the dial wheel 203. The dial wheel 203 is driven to rotate by the dial plate shaft 202, and then the protruding teeth 204 drive the plate on the conveying roller 101 below. The plate is driven to forwardly convey by the dial wheel 203 and the conveying roller 101.

[0056] The extrusion mechanism and the main cleaning mechanism are alternately arranged above the conveying roller 101. The extrusion mechanism is used for extruding the plate to forwardly convey and avoid the plate from being deviated left and right when the main cleaning mechanism cleans the plate. The main cleaning mechanism is used for synchronously cleaning the upper surface and the lower surface of the plate. As shown in the figure, the extrusion mechanism comprises a synchronous plate 205, a guide column 206, a linear bearing 207, a lifting plate 208, a folding plate 209, an adjusting groove 210, a fastening bolt 211, a fastening nut 212, a reset spring 213, a mounting sleeve 214 and an extrusion roller 215. Figure 6

[0057] A jacking cylinder is arranged below the conveyor table, and the piston rod of the jacking cylinder is connected with the synchronous plate 205. The synchronous plate 205 is driven to move up and down by the jacking cylinder. The synchronous plate 205 can ensure the synchronization of the lifting of the multiple groups of extrusion mechanisms above the conveying roller 101 and improve the consistency of the cleaning of the plate surface by the main cleaning mechanism.

[0058] The linear bearing 207 is fixed on the outer side of the conveyor table. One end of the guide column 206 is fixed on the synchronous plate 205, and the other end of the guide column 206 is fixed with the lifting plate 208 through the linear bearing 207. The lifting plate 208 is driven to move up and down by the jacking cylinder. The folding plate 209 is integrally connected to the inner side of the lifting plate 208 and extends towards the side close to the conveying roller 101. The folding plate 209 is arranged perpendicularly to the lifting plate 208.

[0059] The adjusting groove 210 penetrates the folding plate 209 and has a round rectangular shape. The adjusting groove 210 ensures that the extrusion roller 215 has an up-down adjusting space, thereby meeting the extrusion and cleaning work of plates with different thicknesses. An adjusting shaft is arranged in the adjusting groove 210. The extrusion roller 215 is sleeved on the adjusting shaft through a bearing. When the plate is forwardly conveyed, the plate is extruded by the extrusion roller 215 and the conveying roller 101, thereby avoiding the deviation of the position of the plate during cleaning (the material of the extrusion roller is rubber, which avoids damaging the surface of the plate).

[0060] ​Mounting sleeves 214 are fixed at both ends of the adjusting shaft. Fastening bolts 211 are fixed to the top of the mounting sleeves 214 and pass through the lifting plate 208 (the lifting plate 208 has a through hole with a diameter larger than the outer diameter of the fastening bolt 211, ensuring that the fastening bolt 211 can be vertically adjusted within the through hole). Fastening nuts 212 are screwed onto the fastening bolts 211 and rest against the upper surface of the lifting plate 208. After adjusting the position of the fastening bolts 211, the mounting sleeves 214 are fixed in place by screwing on the fastening nuts 212.

[0061] The return spring 213 is sleeved on the fastening bolt 211, with its top abutting against the lower surface of the lifting plate 208 and its bottom abutting against the upper surface of the mounting sleeve 214. When the position of the mounting sleeve 214 is adjusted upwards, the return spring 213 is compressed, causing it to deform. The deformed return spring 213 then generates a reverse force, which acts on the mounting sleeve 214.

[0062] Under the action of this reverse counterforce, the fastening bolt 211 can be pulled down to ensure that the fastening bolt 211 and the fastening nut 212 are screwed together more tightly, so as to prevent the fastening nut 212 from affecting the position of the extrusion roller 215 due to loosening when the plate is extruded. Moreover, relying on the elasticity of the return spring 213, the plate can also be extruded elastically, avoiding rigid extrusion that damages the plate.

[0063] The main cleaning mechanism is positioned above the conveyor roller 101 and alternates with the extrusion mechanism to simultaneously clean the upper and lower surfaces of the sheet material. For example... Figure 5 , 8 The diagram shows the structure of the main cleaning mechanism, which includes a servo motor 216, an eccentric wheel 217, a coupling 218, a drive plate 219, a guide plate 220, a guide groove 221, a scrubbing plate 222, a fixing plate 223, a cleaning roller 224, a water pipe connecting plate 225, a water pipe groove 226, a cleaning pipe 227, and a nozzle 228. The servo motor 216 is fixed to the bottom of the conveyor platform. The eccentric wheel 217 is connected to the servo motor 216. One end of the coupling 218 is rotatably connected to the eccentric wheel 217, and the other end is rotatably connected to the drive plate 219. The guide plate 220 is fixed to the conveyor platform, and a guide groove 221 is formed on the guide plate 220. The drive plate 219 is fitted into the guide groove 221. When the servo motor 216 rotates, it drives the drive plate 219 to move linearly via the eccentric wheel 217.

[0064] The scouring pad 222 is slidably mounted on the conveyor platform via a slide rail and a slider, and is connected to the drive plate 219. The drive plate 219 drives the scouring pad 222 to move linearly, and the direction of movement of the scouring pad 222 is perpendicular to the conveying direction of the conveyor roller 101. Figure 3From the perspective of the plate, the plate moves from right to left, and the rubbing plate 222 moves from front to back, thereby completing the cleaning of the surface of the plate.

[0065] The fixed plate 223 is fixed to the rubbing plate 222 by a stand, and the cleaning roller 224 is rotatably installed on the fixed plate 223 by a bearing seat. A polishing cloth is sleeved on the cleaning roller 224, which is used to clean and polish the plate conveyed by the conveying roller 101.

[0066] The main cleaning mechanism between the two adjacent groups of extrusion mechanisms is divided into upper and lower parts. The upper part is used to clean and polish the upper surface of the plate, and the lower part is used to clean and polish the lower surface of the plate. The two parts are completely the same, and the difference is that the upper part of the main cleaning mechanism is installed on the outer support by a guide column and a guide sleeve, and is lowered under the drive of the lifting cylinder, thereby changing the distance between the main cleaning mechanism and the conveying roller 101 to meet the cleaning and polishing of plates of different thicknesses.

[0067] The second difference is that the moving direction of the rubbing plate 222 is different, that is, one group of rubbing plates 222 moves from front to back, and the other group of rubbing plates 222 moves from back to front, that is, the running directions of the two groups of rubbing plates 222 are opposite. Compared with the same direction movement of the two groups of rubbing plates 222, the opposite movement can form a counteraction between each other, thereby keeping the conveying position of the plate from shifting. The same direction movement easily pushes the plate forward or backward, which affects the normal cleaning of the plate and the side cleaning of the next process.

[0068] The water pipe connecting plate 225 is fixed to the fixed plate 223 and located on both sides of the cleaning roller 224. The water pipe connecting plate 225 is provided with a water pipe groove 226, and the cleaning pipe 227 is inserted into the water pipe groove 226 and can rotate an angle in the water pipe groove 226. When cleaning the plate, the cleaning pipe 227 can spray cleaning water to any position of the plate, thereby improving the cleaning effect and avoiding the splash blind area of the cleaning water.

[0069] The spray head 228 has multiple groups and is arranged on the cleaning pipe 227 and connected to the inside of the cleaning pipe 227. The spray head 228 faces the cleaning roller 224. When the plate is conveyed, the spray head 228 sprays cleaning water to the upper and lower surfaces of the plate, thereby improving the cleaning effect of the plate.

[0070] The second cleaning assembly 3 is arranged on one side of the first cleaning assembly 2 and is used to clean the side of the plate, such as Figures 9-11As shown, it is a structural schematic view of the second cleaning assembly 3, which comprises a turnover mechanism and a side cleaning mechanism. The turnover mechanism has two groups, one of which is used to drive the cleaned plate to turn a certain angle, and the other is used to receive the plate after turning. The side cleaning mechanism is arranged between the two groups of turnover mechanisms and is used to clean the side of the plate. Each group of turnover mechanisms comprises a turnover plate 301, a pushing roller 302, a support plate 303, an extension plate 304, a stop wheel 305, a ball screw 306, a rack 307, a contact gear 308, a first pivot plate 310 and a second pivot plate 311.

[0071] The ball screw 306 is fixed on the conveyor table, and the rack 307 is fixed on the movable part of the ball screw 306, which drives the rack 307 to move. The second pivot plate 311 is fixed on the conveyor table, and the second pivot plate 311 is pivotally connected with the first pivot plate 310. The turnover plate 301 is fixed on the side of the first pivot plate 310 away from the second pivot plate 311.

[0072] The bottom of the turnover plate 301 is fixed with the contact gear 308 engaged with the rack 307. The contact gear 308 is in the shape of a sector. When the rack 307 moves, it drives the turnover plate 301 to rotate through the engagement with the contact gear 308. By setting the mutually engaged rack 307 and contact gear 308, the angle of the turnover plate 301 can be controlled, thereby realizing multi-angle turning of the turnover plate 301, and the cleaning place is more flexible and variable when cleaning the side of the plate, avoiding the occurrence of cleaning blind area.

[0073] Moreover, by setting the mutually engaged rack 307 and contact gear 308, it is easier to adjust the angle of the turnover plate 301. Every time a group of teeth on the rack 307 moves, the turnover plate 301 will turn an angle, which is more convenient and flexible to control.

[0074] The support plate 303 is integrally connected to the top of the side of the turnover plate 301 and is perpendicular to the turnover plate 301. The extension plate 304 is integrally connected to the side of the support plate 303 away from the turnover plate 301 and extends inward. The pushing roller 302 is rotatably installed on the turnover plate 301 through a bearing seat. The stop wheel 305 is rotatably installed on the inner side of the extension plate 304 and is arranged at intervals. The plate cleaned by the first cleaning assembly 2 is conveyed to the pushing roller 302, which drives the turnover plate 301 to rotate under the drive of the lower ball screw 306, thereby driving the preliminarily cleaned plate to turn a certain angle.

[0075] Since the turnover plate 301 is in an inclined state, the plate is easy to slide down to the low side at this time, so the stop wheel 305 is arranged to support the plate in the inclined state, avoiding the plate from sliding down from one side of the flexible plate washer.

[0076] The side cleaning mechanism is arranged between the two groups of turnover mechanisms. One group of turnover mechanisms turns the plate to a specified angle, and then the plate is transported to the other group of turnover mechanisms, and the side of the plate is cleaned by the side cleaning mechanism. Finally, the other group of turnover mechanisms is reset, and the plate cleaned on three sides can be transported back to the lower conveying roller 101.

[0077] As shown in Figure 12 The structure of the side cleaning mechanism is shown in the figure. The side cleaning mechanism includes a vertical plate 312, an adjusting cylinder 313, an adjusting plate 314, a rotating cylinder 315, a rotating plate 316, and a brush head 317. The vertical plate 312 is fixed on the conveyor platform. The cylinder body of the adjusting cylinder 313 is fixed on the vertical plate 312. The adjusting plate 314 is connected to the guide rod of the adjusting cylinder 313, and is moved inward by the adjusting cylinder 313.

[0078] The rotating cylinder 315 is fixed on the side of the adjusting plate 314 away from the vertical plate 312. The rotating plate 316 is fixed on the rotating part of the rotating cylinder 315, and is rotated by the rotating cylinder 315. The brush head 317 is arranged on the side of the rotating plate 316 away from the vertical plate 312. By arranging the rotating turnover plate 301 and the brush head 317, the side of the plate can be cleaned at any position, not just the side of the plate.

[0079] As shown in Figure 13 The first cleaning assembly 2 is used to clean the upper and lower surfaces of the plate (i.e., the a surface and the b surface). The second cleaning assembly 3 can not only clean the side of the plate (i.e., the c surface), but also clean at any angle between the a surface and the c surface.

[0080] When the plate is being edge sealed, some glue will remain on the side. At this time, the second cleaning assembly 3 is needed to clean the remaining glue. Because the glue has peristaltic properties, after being cleaned by the first cleaning assembly 2, the glue may peristaltic towards the side of the plate. After being cleaned by the second cleaning assembly 3, the glue may again peristaltic towards the upper surface of the plate (i.e., when the first cleaning assembly 2 is cleaning, the glue peristaltic from the a surface to the c surface; when the second cleaning assembly 3 is cleaning, the glue peristaltic again from the c surface to the a surface).

[0081] Therefore, the rotating turnover plate 301 and the brush head 317 are arranged to clean the side of the plate at any angle, improving the cleaning effect of the plate.

[0082] The plate multi-surface cleaning equipment also includes a pushing mechanism, which has two groups. One group is located between the first cleaning assembly 2 and the second cleaning assembly 3, and is used to push the plate cleaned initially to one side, facilitating the plate to enter the pushing roller 302 of the second cleaning assembly 3. Because the stacking assembly 1, the first cleaning assembly 2, and the second cleaning assembly 3 are all arranged centrally, if the position of the plate is not adjusted, the plate will collide with the supporting plate 303.

[0083] Another set of pushing mechanisms is arranged between the second cleaning assembly 3 and another set of stacking assemblies 1, which pushes the board after the position adjustment of the previous step to the central position, facilitating the piece-by-piece collection of the stacking assembly 1.

[0086] Firstly, the board is placed on the conveying roller 101 by one of the stacking assemblies 1, and the board on the conveying roller 101 is pushed forward into the first cleaning assembly 2 under the action of the pin wheel 203 and the protruding teeth 204;

[0087] The board is forwardly conveyed by the extrusion of the extrusion roller 215 and the conveying roller 101, and then the upper and lower surfaces of the board are cleaned by the main cleaning mechanism. After the cleaning, the board is pushed to one side by the pushing plate 231;

[0088] The board after the preliminary cleaning enters the second cleaning assembly 3, is turned over by the turnover plate 301 to a certain angle, and the side of the board is cleaned under the action of the brush head 317. After the cleaning, the board is reset and falls on the conveying roller 101 below;

[0089] The board is pushed by the next set of pushing plates 231 to return to the central position, and finally, the piece-by-piece collection of the cleaned board is completed by another set of stacking assemblies 1.

[0090] With reference to the following drawings, the embodiment further provides a cleaning process using the plate multi-surface cleaning equipment as described above, which comprises the following steps:

[0091] Step one: placing the board on the conveying roller 101 by the stacking assembly 1;

[0092] Step two: conveying the board to the extrusion mechanism by the conveying roller 101, and elastically extruding and limiting the board by the extrusion mechanism to avoid the deviation of the board during the cleaning;

[0093] Step three: conveying the board forward to the main cleaning mechanism by the conveying roller 101, and cleaning the upper and lower surfaces of the board by the relatively moving cleaning rollers 224;

[0094] Step four: conveying the board after the preliminary cleaning in step three to the second cleaning assembly 3 by the conveying roller 101, and turning over the board by the turnover plate 301;

[0095] Step five: side cleaning mechanism is used to clean the side of the plate after being turned over in step four;

[0096] Step six: the plate after being cleaned in step five is collected by the stacking assembly 1 piece by piece.
