Description

[0001] This application is a divisional application of the application with the application date of July 31, 2018, the application number of 201810859173.7, and the name of Brush roller type cleaning mechanism for floor forming. TECHNICAL FIELD

[0002] The application belongs to the field of floor production equipment, and particularly relates to a roller brush type cleaning process for floor forming. BACKGROUND

[0003] In recent years, indoor decoration largely adopts solid wood floor, solid wood composite floor and the like as ground decoration materials. The solid wood floor has the problems of shortage of high-quality wood and low utilization rate of wood, and some reinforced floors and composite floors appear in the market to meet the needs of consumers. However, in use, the glue used in the compounding emits a lot of harmful substances (such as formaldehyde), which seriously affects people's health. Therefore, a new type of environmentally friendly wood-plastic composite material product is gradually formed. In the production of medium-density fiberboard, wood phenol generated in the process is added to regenerated plastic to form a wood-plastic composite material through a granulating device, and then the wood-plastic composite material is extruded to form a co-extruded plate. Then, the surface of the co-extruded plate after forming is skinned (patterned decoration layer) to completely composite the floor.

[0004] However, in actual use, the surface layer (i.e. the patterned decoration layer) of the co-extruded plate has the problem of not being firmly bonded to the co-extruded plate, and is more likely to cause peeling or warping, so that the quality of the floor cannot be recognized by consumers, and therefore it is difficult to open up the sales market of this type of floor.

[0005] Therefore, in order to overcome the problem of not being firmly bonded, the applicant found that cleaning the bonding surface during gluing is very important. The ordinary cleaning method only removes the sundries on the bonding surface to ensure the uniformity of the glue application and thus improve the bonding strength. However, the peel strength of the produced product is still difficult to meet the use requirements. Therefore, the cleaning process is improved in this application. A colorless and volatile liquid and a resin are mixed in a certain proportion to form a cleaning liquid. The cleaning liquid not only removes dirt and impurities from the bonding surface, but also forms a resin solidification layer on the bonding surface. Therefore, the amount of glue applied in the subsequent gluing process can be reduced, and the gluing of the surface layer and the co-extruded plate is more beneficial, thereby greatly improving the peel resistance of the surface layer. SUMMARY

[0006] The technical problem to be solved by the application is to overcome the shortcomings of the prior art and provide an improved brush roller type cleaning process for floor forming. The surface of the substrate is cleaned again by using a cleaning agent under the premise of removing sundries from the surface of the substrate, so that a cleaning agent layer is formed on the surface of the substrate to facilitate the gluing of the surface layer.

[0007] To solve the above technical problems, the application adopts the following technical solutions:

[0008] A roller brush type cleaning process for floor forming, which adopts a cleaning mechanism including a first cleaning unit for removing impurities from the surface of a substrate, and a second cleaning unit in connection with the first cleaning unit and using a cleaning solvent to clean the gluing surface of the substrate, the second cleaning unit including a cleaning tank, a track frame, a carrier trolley, a brush roller, and a cleaning solvent spraying assembly above the brush roller, wherein the track frame has a feeding limit, a downward limit, and a feeding limit, and the track frame includes a shared track horizontally arranged near the end of the first cleaning unit, a brushing track vertically extending downward from the shared track, a conveying track horizontally extending away from the end of the first cleaning unit from the shared track, and a turnout arranged at the junction of the brushing track and the conveying track, the brush roller and the cleaning solvent spraying assembly being located below the conveying track and away from the side of the first cleaning unit, and the cleaning process includes the following steps:

[0009] S1, substrate cleaning

[0010] The substrate is horizontally transmitted, and the impurities on the upper and lower surfaces of the substrate are brushed off by the first cleaning unit, and then the substrate is transported into the cleaning tank under the driving of the conveying roller;

[0011] S2, substrate roller brushing

[0012] The substrate transported into the cleaning tank is carried by the carrier trolley, and the shared track and the brushing track are connected by the turnout, the spray head is opened, the brush roller rotates around its own axis, and then the surface to be glued of the substrate is brushed by the brush roller during the conversion of the carrier trolley from the horizontal state to the vertical state, until the carrier trolley moves to the downward limit, the excess cleaning liquid on the surface of the substrate flows back to the cleaning tank, and the carrier trolley is reversely driven to convert from the vertical state to the horizontal state, and the brush roller brushes the surface of the substrate again during the conversion, until the carrier trolley moves to the feeding limit, and the brushing of the surface to be glued of the substrate is completed.

[0013] S3, substrate transfer

[0014] After the brushing of the surface to be glued of the substrate is completed, the turnout is rotated to connect the shared track and the conveying track, and then the carrier trolley moves to the conveying track, and when the carrier trolley moves to the feeding limit, the substrate is horizontally transported to the forming equipment by the conveying roller to complete the cleaning process of the surface of the substrate.

[0015] According to one specific embodiment and preferred aspect of the present application, the carriage trolley moves from right to left in S1, wherein the feeding limit is located at the right side of the common track and close to the first cleaning unit to form a feeding limit port; the downward limit is located at the bottom of the brushing track to form a downward limit port; the feeding limit is located at the left end of the conveying track to form a feeding limit port. In short, the brushing track comprises an arc segment curved downward from the horizontal direction, a vertical segment extending vertically from the lower end of the arc segment, and the second cleaning unit further comprises a downward limit port arranged at the bottom of the vertical segment, a feeding limit port arranged at the end of the conveying track away from the common track, and a feeding limit port arranged at the common track close to the first cleaning unit. When the carriage trolley collides with the downward limit port, the carriage trolley stops moving downward, at this time, the brush roller is flush with or protrudes above the upper edge of the vertical substrate, and simultaneously starts to move upward for resetting under the reverse driving of the carriage trolley. Therefore, the position of the carriage trolley movement or parking is limited by the arrangement of the limit ports.

[0016] Preferably, when the carriage trolley moves to the position of the downward limit port, the brush roller is flush with or protrudes above the upper edge of the vertical substrate.

[0017] According to another specific embodiment and preferred aspect of the present application, the turnout is arranged at the junction of the brushing track and the conveying track, when the turnout connects the common track and the brushing track, the turnout intercepts the conveying track and constitutes the upper track of the brushing track part; when the turnout connects the common track and the conveying track, the turnout intercepts the brushing track and constitutes the lower track of the conveying track part. In some embodiments, the brush roller is arranged horizontally extending along the direction perpendicular to the brushing track.

[0018] According to another specific embodiment and preferred aspect of the present application, the spraying assembly comprises a channel pipe positioned above the side of the brush roller and extending along the length direction of the brush roller, a plurality of spray heads arranged in communication with the channel pipe and side by side, and a water pump and a connecting pipe for pumping the cleaning solvent at the bottom of the cleaning tank to the channel pipe, wherein the plurality of spray heads spray the cleaning solvent to the surface of the brush roller.

[0019] In some embodiments, the carriage trolley comprises a frame, wheels, a driver, and a suction clamp arranged on the frame and capable of being negatively adsorbed on the opposite surface of the substrate to be glued, wherein when the carriage trolley moves to the feeding limit, the carriage trolley stops translating, and the negative pressure of the suction clamp disappears. In short, the suction clamp maintains negative adsorption during the movement and brushing of the carriage trolley.

[0020] According to another specific embodiment and preferred aspect of the present application, the conveying rollers are respectively located at the inlet and outlet ends of the second cleaning unit and are arranged flush with the top surface of the suction clamp of the carriage trolley in the horizontal state. In order to facilitate the entry and exit of the substrate into and out of the cleaning tank.

[0021] In addition, the first cleaning unit used in S1 comprises a positioning frame and a strip brush arranged on the positioning frame, wherein the strip brush is arranged in a direction intersecting the translation direction of the substrate, and the bristles of the strip brush brush off the impurities on the surface of the substrate.

[0022] Preferably, the strip brushes form a plurality of groups, and each group comprises two strip brushes arranged symmetrically above and below, and the strip brushes brush off the impurities on the upper and lower surfaces of the substrate.

[0023] Thanks to the above technical solutions, the present application has the following advantages compared with the prior art:

[0024] In the prior art floor forming, the adhesion between the skin layer and the co-extruded plate is not firm, which is more likely to cause the skin peeling or lifting, and the quality of the floor cannot be recognized by consumers. The present application ingeniously solves the various deficiencies of the prior floor forming by overall design of the floor cleaning process. After the cleaning process is used, the surface of the substrate is first cleaned by removing the impurities, then the spray head is opened, the brush roller rotates around its own axis, and the brush roller brushes the surface to be glued of the substrate during the conversion of the carrier trolley from the horizontal state to the vertical state. When the carrier trolley moves to the lower limit position, the excess cleaning liquid on the surface of the substrate flows back to the cleaning tank, and the carrier trolley is driven in reverse to convert from the vertical state to the horizontal state. During the conversion process, the brush roller brushes the surface of the substrate again. When the carrier trolley moves to the feeding limit position, the surface brushing of the substrate to be glued is completed. After the surface brushing and brushing of the substrate to be glued are completed, the turnout is rotated to connect the common track and the conveying track, and then the carrier trolley moves to the conveying track. When the carrier trolley moves to the feeding limit position, the substrate is transferred to the forming equipment by the conveying roller in the horizontal direction to complete the cleaning process of the surface of the substrate. Therefore, compared with the prior art, on the one hand

[0025] Under the premise of removing the impurities on the surface of the substrate, the cleaning agent is used to brush the glued surface of the substrate twice during the conversion of the substrate from the horizontal state to the vertical state and from the vertical state to the horizontal state, so that a cleaning agent layer is formed on the surface of the substrate. This not only reduces the amount of glue applied, but also facilitates the gluing of the skin layer and the co-extruded plate, thereby greatly improving the peel strength of the skin layer. On the other hand, it is convenient for the substrate to switch between the horizontal and vertical states, and it is also convenient for the substrate to enter and exit the cleaning tank. In addition, the excess cleaning liquid can be drained back to the cleaning tank. BRIEF DESCRIPTION OF DRAWINGS

[0035] like Figure 1 and Figure 2 As shown, the brush roller cleaning mechanism for floor molding according to this embodiment includes a first cleaning unit 1 for removing impurities from the surface of substrate b, and a second cleaning unit 2 that docks with the first cleaning unit 1 and cleans the adhesive surface of substrate b with a cleaning solvent.

[0036] The first cleaning unit 1 includes a positioning frame 10 and a strip brush 11 disposed on the positioning frame 10. The extension direction of the strip brush 11 intersects with the translation direction of the substrate b, and the bristles of the strip brush 11 remove debris from the surface of the substrate b.

[0037] Multiple sets of strip brushes 11 are formed, with two strip brushes 11 arranged symmetrically in each set, and they remove impurities from the upper and lower surfaces of the substrate b. The strip brushes 11 are also purchased directly from an external supplier, and their specific structure will not be described again here.

[0038] The second cleaning unit 2 comprises a cleaning tank 20, a track frame 21 located in the cleaning tank 20, a carrier trolley 22 slidingly arranged on the track frame 21 and capable of positioning and translating the substrate b from the first cleaning unit 1, a brush roller 23 located in the cleaning tank 20, and a cleaning solvent spraying assembly 24 located above the brush roller 23.

[0039] The track frame 21 comprises a common track 210 arranged horizontally near the end of the first cleaning unit 1, a brushing track 211 bent downward from the common track 210 and extending vertically, a conveying track 212 continuing to extend horizontally from the common track 210 away from the end of the first cleaning unit 1, and a turnout 213 arranged at the junction of the brushing track 211 and the conveying track 212, wherein the turnout 213 is rotationally arranged at the junction of the brushing track 211 and the conveying track 212, when the turnout 213 abuts the common track 210 and the brushing track 211 (as shown in Figure 2 ), the turnout 213 intercepts the conveying track 212 and constitutes the upper rail of the brushing track 211; when the turnout 213 abuts the common track 210 and the conveying track 212 (as shown in Figure 1 ), the turnout 213 intercepts the brushing track 211 and constitutes the lower rail of the conveying track 212.

[0040] As for the turnout 213, the applicant explains that its principle is the same as the turnout used for train track switching, which is a common means, but has not been implemented for floor cleaning.

[0041] The brushing track 211 comprises an arc-shaped segment 211a bent downward from the horizontal direction, and a vertical segment 211b extending vertically from the lower end of the arc-shaped segment 211a, and the second cleaning unit 2 further comprises a downward limit port 2a arranged at the bottom of the vertical segment 211b, feeding limit ports 2b respectively arranged at the end of the conveying track 212 away from the common track 210, and a feeding limit port 2c arranged at the common track 210 near the first cleaning unit 1, when the carrier trolley 22 touches the downward limit port 2a, the carrier trolley 22 stops downward movement, at this time the brush roller 23 is flush with the upper edge of the vertical substrate b, and simultaneously starts upward reset movement under the reverse driving of the carrier trolley 22; when the carrier trolley 22 touches the feeding limit port 2c, the carrier trolley 22 stops translation, and then reversely moves the conveying track 212; when the carrier trolley 22 touches the feeding limit port 2b, the carrier trolley 22 stops translation, and then reversely moves the common track 210 to reset, completing the brush roller of one substrate b. Therefore, in the above-mentioned repeated process of the carrier trolley 22, the brush rollers of multiple substrates b are realized block by block.

[0042] In this example, the brush roller 23 and the cleaning solvent spraying assembly 24 are located below the conveying track 212 and on the side of the brushing track 211 away from the first cleaning unit 1. When the turnout connects the common track and the brushing track, the substrate is switched between the horizontal and vertical states during the movement of the carrier trolley to or out of the brushing track, and the brush roller brushes the surface of the substrate to be glued. When the turnout connects the common track and the conveying track, the brushed substrate is horizontally transferred to the forming equipment.

[0043] As for the structure of the brush roller 23, it is directly purchased from the applicant and belongs to a conventional product, and its specific structure will not be described in detail here.

[0044] However, in this example, the brush roller 23 is arranged horizontally along a direction perpendicular to the brushing track 211 and rotates around its own axis.

[0045] At the same time, the carrier trolley 22 includes a frame 220, wheels 221, a drive, and a suction chuck 222 arranged on the frame 220 and capable of being negatively adsorbed to the opposite surface of the substrate b to be glued. The use of the carrier trolley is very common in the art, and negative adsorption is also a conventional device, which will not be described in detail here.

[0046] The spraying assembly 24 includes a channel pipe 240 positioned above the side of the brush roller 23 and extending along the length direction of the brush roller 23, a plurality of spray heads 241 arranged in communication with the channel pipe 240 and side by side, and a water pump 242 and a connecting pipe 243 for pumping the cleaning solvent at the bottom of the cleaning tank 20 to the channel pipe, wherein the plurality of spray heads 241 spray the cleaning solvent to the surface of the brush roller.

[0047] In order to ensure uniformity of spraying, in this example, the plurality of spray heads 241 are uniformly distributed along the length direction of the channel pipe 240.

[0048] Then, when the carrier trolley 22 moves to the lower limit port 2a position, the substrate b is located above the liquid level of the cleaning solvent at this time, and the excess cleaning liquid of the brush roller flows back into the cleaning tank 20.

[0049] In addition, in this example, the cleaning mechanism further includes a conveying roller 3 arranged at the inlet and outlet ends of the second cleaning unit 2 and flush with the conveying roller 3. The conveying roller 3 is connected to realize the transfer of the substrate.

[0050] In summary, the cleaning process of the present embodiment is as follows (combined with the accompanying drawings) Figure 1 and 2 It should be noted that the carrier trolley in the present application is only one, and the three in the accompanying drawings mainly represent the carrier trolley in three different position states, so as to facilitate understanding:

[0051] S1, substrate cleaning

[0052] The substrate b is horizontally transported from right to left, first passing through the upper and lower symmetrically arranged strip brush 11 to brush off the impurities on the upper and lower surfaces of the substrate b, and then transported into the cleaning tank 20 under the drive of the conveying roller 3;

[0053] S2, substrate roller brush

[0054] The substrate entering the cleaning tank 20 continues to move to the left until it moves to the adsorption chuck 222 of the carrier trolley 22, then forms a negative pressure to position the substrate b and the carrier trolley 22, and by the turnout 213, the common track 210 and the brushing track 211 are connected, the spray head 241 is opened, the brush roller 23 rotates around its own axis, then in the process of the carrier trolley 22 converting from a horizontal state to a vertical state, the surface of the substrate to be glued is brushed by the brush roller 23, until the carrier trolley 22 moves to the lower limit port 2a position, the excess cleaning liquid on the surface of the substrate flows back into the cleaning tank 20, at the same time, the carrier trolley 22 is reversely driven, and then converted from the vertical state to the horizontal state, and in the conversion process, the brush roller 23 brushes the surface of the substrate again, until the carrier trolley 22 moves to the feeding limit port 2c, the carrier trolley 22 stops moving, the turnout 213 is rotated to connect the common track 210 and the conveying track 212, then the carrier trolley 22 moves to the conveying track 212, when the carrier trolley 22 moves to the feeding limit port 2b, the carrier trolley 22 stops moving;

[0055] S3, substrate transfer

[0056] The negative pressure of the adsorption chuck 222 disappears, and the substrate b on the carrier trolley 22 is transferred to the forming equipment by the conveying roller 3, then the carrier trolley 22 is reset and moves to the feeding limit port 2b again, then the carrier trolley 22 stops moving, thereby completing the cleaning process of the surface of the substrate b.

[0057] From the above, after adopting the cleaning process, the surface of the substrate is first subjected to the impurity removal treatment of the first cleaning, then the spray head is opened, the brush roller rotates around its own axis, and the brush roller is used to brush the surface of the substrate to be glued during the conversion of the carriage trolley from the horizontal state to the vertical state. When the carriage trolley moves to the lower limit position, the excess cleaning liquid on the surface of the substrate flows back to the cleaning tank, and the carriage trolley is driven in reverse to convert from the vertical state to the horizontal state. During the conversion process, the brush roller brushes the surface of the substrate again, and when the carriage trolley moves to the feeding limit, the brushing of the surface of the substrate to be glued is completed. After the brushing and brushing of the surface of the substrate to be glued, the common track and the conveying track are connected by rotating the turnout, and then the carriage trolley moves to the conveying track. When the carriage trolley moves to the feeding limit, the substrate is transferred horizontally to the molding equipment by the conveying roller to complete the cleaning process of the surface of the substrate. Therefore, compared with the prior art, the present application has the following advantages: firstly, after the impurities on the surface of the substrate are removed by the preliminary brushing in the present application, the surface of the substrate is brushed by two cleaning liquids to ensure that the surface of the substrate is free of impurities and a layer of cleaning solvent (containing components including resin and colorless volatile liquid) is formed. After drying, a solidified resin layer is formed, thereby facilitating the subsequent gluing of the skin layer, i.e., the amount of glue applied can be reduced, and the gluing of the skin layer and the co-extruded plate is more beneficial, thereby greatly improving the peel strength of the skin layer. Secondly, the horizontal and vertical states of the substrate can be easily switched, and the substrate can be easily fed into and out of the cleaning tank. Thirdly, the excess cleaning liquid can be drained back into the cleaning tank. Fourthly, the position of the carriage trolley is limited by the limit port, especially when the carriage trolley moves to the lower limit port position, the brush roller is flush with or protrudes above the upper edge of the vertical substrate. Fifthly, the brush roller is horizontally extended along the direction perpendicular to the brushing track and rotates around its own axis. Sixthly, the positioning of the substrate is completed by the negative pressure disappearance and adsorption mode, and the top surface of the adsorption clamp of the conveying roller and the horizontal state of the carriage trolley is flush, so as to facilitate the feeding of the substrate into and out of the cleaning tank. Seventhly, the brush is formed in multiple groups, each group having two brushes arranged symmetrically above and below, and the impurities on the upper and lower surfaces of the substrate are brushed away.

[0058] The above detailed description of the present application is intended to enable those skilled in the art to understand the content of the present application and to implement it, and does not limit the protection scope of the present application. Any equivalent changes or modifications made in accordance with the spirit and essence of the present application should be covered within the protection scope of the present application.
