Description

[0001] This application is a divisional application of the application with the application date of July 31, 2018, the application number of 201810859186.4, and the name of the upper roller brush type automatic cleaning machine for floor forming. TECHNICAL FIELD

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

[0003] In recent years, indoor decoration largely uses 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 can emit 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 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 the present application, a colorless and volatile liquid and a resin are mixed in 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 strength. SUMMARY

[0006] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a new upper roller brush type cleaning process for floor forming.

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

[0008] The present application discloses a floor forming upper roller brush cleaning process, which comprises a feeding step, a cleaning step and a collecting step. The cleaning step comprises: S1, forming a coating layer by roller brush, the substrate to be cleaned is sent into the cleaning area by the feeding step, and the surface of the substrate is cleaned by removing the impurities; the substrate is then sent into the cleaning tank, and the cleaning solvent is brushed onto the upper surface of the substrate by the spray and the roller brush, and a coating layer containing resin is formed on the upper surface of the substrate in the second cleaning; S2, solidification of the coating layer, the coating layer is solidified to form a resin solidification layer by drying; the automatic collecting unit in the collecting step comprises a collecting frame, a collecting platform for carrying the substrate, a driving mechanism arranged on the collecting frame and used for driving the collecting platform to move downward step by step, a counting component used for counting the number of stacked substrates, and a connecting mechanism arranged on the collecting frame and used for connecting the substrate to be transferred from the forming equipment, wherein the height of each downward movement of the collecting platform is equal to the thickness of the substrate, and the substrate is horizontally transferred to the collecting platform after drying; when the side edge of the substrate abuts against the positioning rest on the connecting mechanism, the driving mechanism drives the collecting platform to move downward once, and when the first substrate is collected, the bottom surface of the positioning rest abuts against the upper surface of the collecting platform and forms a first slot, and the first substrate is positioned in the first slot from the side edge; when the second substrate is collected, the positioning rest and the first substrate form a second slot, and the second substrate is positioned in the second slot from the side edge; when the Nth substrate is collected, the positioning rest and the uppermost substrate in the stacked substrates form an Nth slot, the Nth substrate is positioned in the Nth slot from the side edge, and the counting is read out by the scale ruler, the pointing scale and the pointer moving synchronously with the collecting platform; when the pointer contacts the upper limit or the lower limit of the scale ruler, a closed circuit is formed, and the driving mechanism stops moving.

[0009] Preferably, the first cleaning unit comprises a positioning frame and a strip brush arranged on the positioning frame, wherein the strip brush extends in a direction intersecting the substrate translation direction, and the bristles of the strip brush brush off the impurities on the surface of the substrate. In some embodiments, the strip brush forms a plurality of groups, each group comprising two strip brushes arranged symmetrically above and below, and the impurities on the upper and lower surfaces of the substrate are brushed off.

[0010] According to one embodiment and preferred aspect of the present application, the spray component is arranged close to the roller brush, and comprises a communication pipe extending along the length direction of the roller brush, a plurality of spray heads in communication with the communication pipe and arranged side by side, a spray hose connected to the bottom of each spray head, and a water pump and a connecting pipe for pumping the cleaning solvent to the communication pipe, wherein the bottom of the spray hose is arranged downwardly and obliquely from top to bottom towards the roller brush, and the cleaning solvent is sprayed from the bottom of the spray hose towards the surface of the substrate.

[0011] Preferably, for the uniformity of the spraying, the plurality of spraying heads are uniformly distributed along the length direction of the communicating pipe, and the vertical distance between the bottom of the spraying hose and the substrate is adjusted up and down as needed, but the flow direction of the solvent formed by the spraying hose is consistent with the direction of the substrate. In short, on the one hand, it is convenient for the transmission of the substrate; on the other hand, it ensures that the roller brush is always in a wet state, thereby ensuring the uniformity of brushing and providing favorable conditions for forming a cured resin layer.

[0012] According to another specific implementation and preferred aspect of the present application, the docking mechanism comprises a docking rack positioned on the material receiving rack and having a positioning abutment, a docking roller located in front of the positioning abutment and used to push the substrate out of the drying unit to the positioning abutment, an extension rod extending horizontally from both ends of the docking rack to the drying unit, and a docking roller provided on the extension rod and rotating around a vertical axis. The positioning abutment is located above the side of the material receiving platform. When the side edge of the substrate abuts against the positioning abutment, the docking roller stops moving, and the driving mechanism drives the material receiving platform to descend once. The docking rollers are suspended above the sides of the material receiving platform, and when the substrate is conveyed to the docking roller, the docking rollers on both sides roll and fit on the opposite sides of the substrate. Here, the positioning abutment has two functions: first, it serves as a reference to align the multiple stacked substrates on the side where the positioning abutment is located; second, it serves as a certain limiting and guiding function when the material receiving platform is descending, reducing the deviation of the substrate during the descending process. At the same time, considering the possible deviation of the substrate during the conveying process, which may affect the neatness of the stacked substrates, when the substrate is conveyed to the docking roller, the docking rollers on both sides roll and fit on the opposite sides of the substrate. By arranging the docking rollers on both sides, the deviation of the substrate during the conveying process is limited, thereby improving the neatness of the stacked substrates.

[0013] In some specific implementations, there are at least two docking rollers on each side of the extension rod, and the roller surface of the docking roller in contact with the side edge of the substrate is flush with the docking roller. The docking roller is hung on the inside of the extension rod by a docking rod, and / or the docking roller comprises a roller body rotatingly arranged at the lower part of the docking rod, and an anti-slip roller sleeve sleeved on the outer periphery of the roller body. Here, the layout of the two docking rollers is simple, and the two docking rollers on both sides can be symmetrically arranged or staggered with each other. The anti-slip roller sleeve avoids slipping and deviation during the movement of the substrate, thereby improving the neatness of the stacked substrates.

[0014] According to another specific implementation and preferred aspect of the present application, the material receiving rack comprises a base, a stand located on the side of the base away from the drying unit, and a docking rack positioned at the position where the stand aligns with the discharge port of the drying unit, and the docking rack is movably arranged on the stand along the height direction of the stand.

[0015] In some embodiments, the counting component includes a scale ruler formed on the column and having a unit of thickness of each substrate, a pointer arranged on the substrate receiving platform corresponding to the side where the column is located and pointing to the scale ruler, and a smart controller connected to the driving mechanism, wherein the smart controller includes contact switches arranged at upper and lower limit positions of the scale ruler respectively, and when the pointer contacts the contact switch at the upper or lower limit of the scale ruler, a closed circuit is formed and the driving mechanism stops moving. When substrates of different thicknesses are processed, only the corresponding scale ruler needs to be replaced to achieve counting of the substrate. When the pointer contacts the contact switch at the upper limit, the driving mechanism stops ascending movement; when the pointer contacts the contact switch at the lower limit, the driving mechanism stops descending movement. As for the driving mechanism, it is similar to an elevator (or a lifting platform) and can not only descend but also ascend, which is a common design in the field and will not be described in detail.

[0016] In addition, the drying unit includes a drying section and an air drying section, wherein the air drying section includes fans formed on opposite sides of the substrate conveying channel to form rapid gas circulation. Specifically, the drying section mainly uses a heating rod to heat the substrate; and the air drying section mainly uses fans to form rapid air flow to remove heat generated during drying, thereby forming a resin curing layer on the surface of the substrate.

[0017] Thanks to the above technical solutions, the present application has the following advantages compared with the prior art:

[0018] In existing flooring molding processes, weak adhesion between the surface layer and the co-extruded board can easily lead to peeling or warping, resulting in flooring quality that fails to meet consumer expectations. This invention addresses this issue with a cleaning process. First, the substrates are fed piece by piece, with each substrate undergoing a primary surface cleaning to remove impurities. Then, a secondary cleaning process is performed using spraying and roller brushing to transfer cleaning solvent to the substrate surface, simultaneously forming a resin-containing coating. Next, the surface is dried to form a cured resin layer, completing the automated cleaning process. Finally, with the cooperation of positioning grids and connecting mechanisms, the substrates are stacked and collected with side alignment. Simultaneously, during the descent of the collection platform, substrate misalignment and substrate adhesion are minimized. The automatic counting of stacked substrates during the automatic material collection process completes the automatic material collection step. Therefore, compared with the prior art, this invention not only forms a resin curing layer on the substrate surface to be glued, which is beneficial to the bonding of the skin layer and the co-extruded board, but also reduces the amount of glue applied, thereby greatly improving the peel strength. At the same time, it automates the substrate loading, cleaning, and unloading process, making it simple to operate and easy to implement. On the other hand, it uses one side as a guide for side-aligned stacked material collection. The guide also plays a certain role in limiting and guiding the material collection platform as it descends, reducing substrate displacement during the descent. In addition, the descent of the material collection platform can also automatically count the stacked substrates during collection, and with the assistance of upper and lower limits, it can also intelligently start and stop the lifting and lowering.

[0037] As shown in Figure 1 The upper roller brush type automatic cleaning machine for floor forming of the present embodiment includes a feeding unit A, a roller brush type cleaning mechanism B, a receiving unit C, a drying unit D, and a conveying unit E.

[0038] Specifically, the feeding unit A is combined with the Figure 2 and 3 The feeding unit A is used to push the stacked substrates b to the roller brush type cleaning mechanism B horizontally piece by piece.

[0039] In this example, the feeding unit A includes a bearing platform 1 for placing the stacked substrates b, a lifting mechanism 2 for driving the bearing platform 1 to lift step by step, a pushing mechanism 3 arranged on one side of the bearing platform 1, and a counting mechanism 4 for counting the number of substrates b fed into the roller brush type cleaning mechanism B, wherein the lifting mechanism 2 lifts the height of each time equal to the thickness of a substrate b, and the pushing mechanism 3 pushes the automatically upwardly aligned substrates b to the roller brush type cleaning mechanism B.

[0040] Specifically, the lifting mechanism 2 includes a base 20, a scissor type support arm 21 arranged between the base 20 and the bearing platform 1, and a driving assembly (not shown in the figure) for driving the scissor type support arm 21 to expand or contract. In short, the lifting mechanism 2 is equivalent to a scissor type lift, and its working principle is exactly the same as that of a scissor type lift, which will not be described in detail here.

[0041] However, the bearing platform 1 of the present application has a smaller area of the orthographic projection on the base 20 than the area of the upper surface of the base 20.

[0042] The pushing mechanism 3 includes a positioning seat 30 positioned on the side of the bearing platform 1 away from the roller brush type cleaning mechanism B, a pushing rod 31 arranged on the positioning seat 30 and capable of moving in the horizontal direction, and a driving member 32 for driving the pushing rod 31 to reciprocate, wherein the pushing rod 31 is arranged in alignment with the roller brush type cleaning mechanism B, and in the reciprocating motion, the pushing rod 31 pushes the automatically upwardly aligned substrates b to the roller brush type cleaning mechanism B piece by piece.

[0043] In order to ensure the ejection effect, in this case, a side of the bearing platform 1 is also provided with a leaning fence A5, and the stacked substrates b abut against the leaning fence A5 from one side.

[0044] Specifically, the leaning fence A5 is located on the opposite sides of the pushing direction of the substrate b. Under the action of the leaning fence A5, the pushing of the substrate b is more stable.

[0045] At the same time, the contact between the pushing rod member 31 and the substrate b is also important, and too much or too little contact will affect the pushing of the substrate b. Then, the effective contact height is 0.5-1 times the thickness of the substrate, wherein the effective contact height is calculated from the top edge of the substrate downward.

[0046] In this case, the effective contact height of the pushing end of the pushing rod member 31 in contact with the substrate b is 0.6 times the thickness of the substrate, that is, the distance between the bottom of the pushing rod member 31 and the next substrate b is 0.4 times the thickness of the substrate b.

[0047] Specifically, the positioning seat 30 includes a positioning rod 300 arranged in alignment with the middle of the stacked substrate, and the pushing rod member 31 is movably arranged at the position where the positioning rod 300 is aligned with the roller brush type cleaning mechanism B.

[0048] The pushing rod member 31 includes a top rod 310 extending in the horizontal direction, and a limiting module 311 arranged at both ends of the top rod 310. When the driving member 32 contacts any one of the limiting modules 311, the driving member 32 moves reversely to realize the reciprocating motion of the pushing rod member 31.

[0049] The driving member 32 includes a transmission gear 32a formed on the upper part of the top rod 310 along the length direction of the top rod 310, and a driving gear 32b arranged on the positioning rod 300 and engaged with the transmission gear 32a.

[0050] In this case, the driving gear 32b has two, and is arranged on the opposite sides of the positioning rod 300 respectively. Therefore, under the synchronous driving of the two driving gears, the reciprocating motion speed of the top rod 310 is effectively improved, and the movement of the top rod 310 is also more stable.

[0051] As for the transmission mode, a driving motor is arranged on the positioning rod 300, and then a belt wheel transmission mode is adopted to synchronously connect the driving motor and the driving gear 32b, wherein the driving motor is located at the top of the driving gear 32b, and the center of the driving gear 32b and the center of the output end of the driving motor form an equilateral triangle, and the driving motor has a forward and reverse rotation mode.

[0052] Meanwhile, the inside of the limiting module 311 is also provided with a tooth groove 311a matched with the driving gear 32b, when the driving gear 32b engages with one of the tooth grooves 311a, the driving motor reverses to rotate to realize the reciprocating motion.

[0053] Then, considering the space occupation, the ejector rod 310 is set as multiple sections to splice and butt joint to form a horizontally arranged rod, and the limiting module 311 is located at the two ends of the rod. The purpose of the multiple sections is to reduce the space occupation of the ejector rod in the non-working state by folding by itself.

[0054] The counting mechanism 4 includes a scale 40 formed on the positioning rod 300 with the thickness of each substrate b as a unit, and a pointer 41 arranged on the side of the bearing platform 1 corresponding to the positioning rod 300 and pointing to the scale. The number of the substrate is obtained by subtracting the reference value from the position value pointed by the pointer, which is very convenient to control.

[0055] Further, the scale 40 is detachably positioned on the positioning rod 300 and can also be adjusted up and down along the height direction of the positioning rod 300. When substrates with different thicknesses are processed, only the corresponding scale needs to be replaced to realize the counting of the substrate.

[0056] Meanwhile, the counting mechanism 4 also includes an intelligent controller 42 connected with the lifting mechanism 2, which includes contact switches k arranged at the upper and lower limit positions of the scale 40. When the pointer 41 contacts the contact switch at the upper or lower limit of the scale 40, a closed circuit is formed, and the lifting mechanism stops moving. In short, when the pointer contacts the contact switch at the upper limit, the lifting mechanism stops ascending; when the pointer contacts the contact switch at the lower limit, the lifting mechanism stops descending.

[0057] In combination with the accompanying drawings, Figure 4 In this example, the roller brush cleaning mechanism B includes a first cleaning unit B1 for removing impurities on the surface of the substrate b, and a second cleaning unit B2 for cleaning the adhesive surface of the substrate b with a cleaning solvent.

[0058] The first cleaning unit B1 includes a positioning frame B10 and a strip brush B11 arranged on the positioning frame B10, wherein the strip brush B11 extends in a direction intersecting the translation direction of the substrate b, and the bristles of the strip brush B11 brush off the impurities on the surface of the substrate b.

[0059] The strip brush B11 forms multiple groups, and each group has two strip brushes B11 arranged symmetrically above and below, and the impurities on the upper and lower surfaces of the substrate b are brushed off. The strip brush B11 is also a directly purchased product, and its specific structure is not repeated here.

[0060] The second cleaning unit B2 comprises a cleaning groove B20, a roller brush B23 located in the cleaning groove B20 and above the substrate b conveying roller, and a cleaning liquid spraying assembly B24 located between the roller brush B23 and the first cleaning unit B1.

[0061] The structure of the roller brush B23 is directly purchased from the applicant and is a conventional product, and thus, the specific structure is not described in detail.

[0062] However, in the example, the roller brush B23 is horizontally arranged along the direction perpendicular to the substrate b translation direction and is rotatably arranged around the axis thereof.

[0063] The spraying assembly B24 is arranged close to the roller brush B23 and comprises a communication pipe 240 located at the right side of the roller brush B23 and extending along the length direction of the roller brush B23, a plurality of spraying heads 241 in communication with the communication pipe 240 and arranged side by side, a spraying hose 242 connected to the bottom of each spraying head 241, and a water pump 243 and a connecting pipe 244 for pumping the cleaning solvent to the communication pipe 240, wherein the bottom of the spraying hose 242 is arranged downwardly and obliquely to the roller brush B23, and the cleaning solvent is sprayed from the bottom of the spraying hose 242 to the surface of the substrate b.

[0064] In order to ensure the uniformity of the spraying, in the example, the plurality of spraying heads 241 are uniformly distributed along the length direction of the communication pipe 240, and the vertical distance between the bottom of the spraying hose 242 and the substrate b is adjusted up and down as needed, but the solvent flow formed by the spraying hose 242 is consistent with the direction of the substrate, which facilitates the transmission of the substrate and ensures that the roller brush B23 is always in a wet state, thereby ensuring the uniformity of the brushing and providing favorable conditions for forming the cured resin layer.

[0065] In addition, in the example, the cleaning mechanism further comprises a conveying roller B3 arranged at the inlet and outlet ends of the second cleaning unit B2 and flush with the conveying roller B3. The conveying roller B3 is connected to realize the transmission of the substrate.

[0066] In short, after the preliminary brushing of the substrate surface in the application, the roller brush is used to ensure that the substrate surface is free of impurities and can form a cleaning solvent layer (containing components including resin and colorless volatile liquid), and after drying, a cured resin layer is formed, thereby facilitating the subsequent skin layer gluing and improving the peel strength of the skin layer.

[0067] In the example, the drying unit D mainly comprises two parts of a drying section D2 and an air drying section D1. The drying section D2 mainly uses a heating rod D20 to heat the substrate b. The air drying section D1 mainly uses a fan D10 to form a rapid airflow to carry away the heat during drying, thereby forming a resin curing layer on the surface of the substrate b.

[0068] Meanwhile, the conveying unit E, which mainly includes the E1 moving roller or the squeezing roller in each unit above for receiving the substrate b, is also a conventional arrangement, which will not be described in detail here.

[0069] In combination with the accompanying Figures 5 to 7 The material receiving unit in this example stacks and collects the substrates b translated out from the drying unit D.

[0070] Specifically, the material receiving unit includes a material receiving rack C1, a material receiving platform C2 for receiving the substrate b, a driving mechanism C3 arranged on the material receiving rack C1 for driving the material receiving platform C2 to move downward step by step, a counting component C4 for counting the number of stacked substrates b, and a connection mechanism 5 arranged on the material receiving rack C1 for connecting the substrate b translated out from the drying unit D, wherein the height of each downward movement of the driving mechanism C3 is equal to the thickness of one substrate b.

[0071] In this example, the drying unit D is located on the right side, and the material receiving unit is located on the left side. The substrate b is translated along the length direction of the substrate b from the right side to the left side for stacking and collecting. After the collection of one substrate b is completed, the material receiving platform C2 is lowered once until the stacking of multiple substrates b is completed.

[0072] However, the neatness of the stacking is completely determined by the performance of the connection mechanism 5. In this example, the following technical means are adopted to achieve higher neatness of the stacking.

[0073] The connection mechanism 5 includes a connection rack 50 positioned on the material receiving rack C1 and having a positioning abutment 50a, a connection roller 51 located in front of the positioning abutment 50a and used for pushing the substrate b translated out from the drying unit D to the positioning abutment 50a, and a driving member (not shown in the figure) for driving the connection roller 51 to rotate, wherein the positioning abutment 50a is located above the left side of the material receiving platform C2. When the side edge of the substrate b abuts against the positioning abutment 50a, the connection roller 51 stops moving, and the driving mechanism C3 drives the material receiving platform C2 to lower once.

[0074] In order to further explain the structure and principle above, in this example, the substrate b is rectangular and is translated along the length direction above the material receiving platform C2. The positioning abutment 50a extends along the width direction of the substrate b.

[0075] Meanwhile, the extension direction of the connection roller 51 is consistent with that of the positioning abutment 50a.

[0076] Then, the bottom surface of the positioning abutment 50a is arranged in parallel with the upper surface of the material receiving platform C2, and the vertical distance between the bottom surface of the positioning abutment 50a and the upper surface of the material receiving platform C2 is an integer multiple of the thickness of the substrate b.

[0077] When the first substrate is collected, the bottom surface of the positioning gate is attached to the upper surface of the receiving platform to form a first notch, and the first substrate is positioned from the side in the first notch; when the second substrate is collected, the positioning gate and the first substrate form a second notch, and the second substrate is positioned from the side in the second notch. When the Nth substrate is collected, the positioning gate and the top substrate of the stacked substrate form the Nth notch, and the Nth substrate is positioned from the side in the Nth notch.

[0078] In this example, the positioning grid 50a serves two purposes: first, it acts as a reference, ensuring that multiple stacked substrates are aligned with the side where the positioning grid is located; second, it provides a certain degree of limitation and guidance when the receiving platform descends, reducing substrate offset during the descent process.

[0079] Meanwhile, considering the potential displacement of substrate b during translation, which could affect the neatness of the laminated substrate, the connecting mechanism 5 in this example also includes extension rods 52 extending horizontally from both ends of the connecting frame 50 towards the forming equipment, and guide rollers 53 mounted on the extension rods 52 and rotating about a vertical axis. The guide rollers 53 are suspended above the sides of the receiving platform C2. When substrate b is conveyed to the connecting rollers 51, the guide rollers 53 on both sides roll and engage with the opposite sides of substrate b. By setting the guide rollers 53 on both sides, the displacement of substrate b during movement is limited, thereby improving the neatness of the laminated substrate.

[0080] Specifically, there are two receiving rollers 53 on each side extension rod 52, and the roller surfaces of the receiving rollers 53 on the same side that contact the side of the substrate b are flush.

[0081] As for the layout of the two receiving rollers 53, it is very simple. The two receiving rollers 53 on both sides can be arranged symmetrically or staggered.

[0082] In this example, the receiving rollers 53 on both sides are symmetrically arranged, and the receiving rollers 53 are suspended on the inner side of the extension rod 52 by the receiving rod 54. The receiving rollers 53 include a roller body 531 rotatably arranged at the lower part of the receiving rod 54 via a bearing 530, and an anti-slip roller sleeve 532 sleeved on the outer periphery of the roller body 531.

[0083] The receiving rack C1 includes a base 10, a column 11 located on one side of the molding equipment, and a connecting frame 50 positioned on the column 11 aligned with the discharge port of the drying unit D. The connecting frame 50 is adjustable and movable along the height of the column 11.

[0084] The counting component C4 includes a scale 40 formed on the column 11 with the thickness of each substrate b as one unit, and a pointer 41 set on the side of the receiving platform C2 corresponding to the column and pointing to the scale 40.

[0085] The scale ruler 40 is detachably positioned on the column 11, and can also be adjusted up and down along the height direction of the column 11. When different thickness of the substrate b is processed, only the corresponding scale ruler 40 needs to be replaced, so as to realize the counting of the substrate.

[0086] Further, the counting assembly C4 further comprises a smart controller 42 in communication with the driving mechanism C3, the smart controller 42 comprises a contact switch k arranged at the upper limit and the lower limit position of the scale ruler 40 respectively, when the pointer 41 contacts the contact switch k at the upper limit or the lower limit of the scale ruler 40, a closed circuit is formed, and the driving mechanism C3 stops moving. In short, when the pointer 41 contacts the contact switch k at the upper limit, the driving mechanism C3 stops ascending movement; when the pointer 41 contacts the contact switch k at the lower limit, the driving mechanism C3 stops descending movement.

[0087] In addition, the driving mechanism C3 comprises a scissors type support arm C30, and a hydraulic oil cylinder (not shown in the figure) for driving the scissors type support arm C30 to expand or contract, the specific principle is similar to the elevator (or lifting platform), which can not only descend, but also lift upward, which belongs to the conventional design in the field, and will not be described in detail here.

[0088] The upper roller brush type cleaning process for floor forming includes feeding step, cleaning step and collecting step. In the feeding step, the laminated substrate b is horizontally pushed to the roller brush type cleaning mechanism B. In the cleaning step, S1, the roller brush forms a brushing layer. First, the substrate to be cleaned is sent into the cleaning area by the feeding step, and the surface of the substrate is treated to remove impurities to complete the first cleaning. Second, the substrate after the first cleaning enters the cleaning tank. Then, the cleaning solvent is brushed onto the upper surface of the substrate by the spray and the roller brush on the upper surface of the substrate, and the brushing layer containing resin is formed on the upper surface of the substrate in the second cleaning. S2, curing of the brushing layer. Under the drying of the drying unit, the brushing layer is cured to form a resin cured layer. The automatic collecting unit used in the collecting step includes a collecting frame, a collecting platform for carrying the substrate, a driving mechanism arranged on the collecting frame for driving the collecting platform to move downward step by step, a counting component for counting the number of laminated substrate blocks, and a connection mechanism arranged on the collecting frame for connecting the self-forming device to transfer the substrate out of the collecting platform. The height of the collecting platform is equal to the thickness of one substrate, and the substrate is transferred horizontally to the collecting platform after drying. When the side edge of the substrate abuts against the positioning rest on the connection mechanism, the driving mechanism drives the collecting platform to descend once. When the first substrate is collected, the bottom surface of the positioning rest is attached to the upper surface of the collecting platform and forms a first slot, and the first substrate is positioned in the first slot from the side. When the second substrate is collected, the positioning rest and the first substrate form a second slot, and the second substrate is positioned in the second slot from the side. When the Nth substrate is collected, the positioning rest and the substrate on the top of the laminated substrate form an Nth slot, and the Nth substrate is positioned in the Nth slot from the side. The scale ruler, the pointer moving synchronously with the collecting platform, and the scale reading count are read out. The scale ruler has upper and lower limit positions. When the pointer contacts the upper or lower limit of the scale ruler, a closed circuit is formed, and the driving mechanism stops moving.

[0089] As can be known from the above, after the cleaning process, the substrate is supplied piece by piece, each piece of substrate is first cleaned by surface impurity removal treatment, then the cleaning solvent is transferred to the upper surface of the substrate by spraying and roller brushing to perform secondary cleaning and form a coating layer containing resin on the surface, then the surface is dried to form a solidified resin layer to complete the automatic cleaning step, then the side alignment type layering is performed under the cooperation of the positioning fence and the connecting mechanism, and the automatic counting of the substrate layering is performed during the descending of the collecting platform to reduce the deviation of the substrate during the descending process, thereby completing the automatic collecting step, therefore, compared with the prior art, the present application can not only form a solidified resin layer on the surface of the substrate to be glued, which is beneficial to the gluing of the skin layer and the co-extruded plate, but also can reduce the amount of glue applied, thereby greatly improving the peel strength, and the automatic loading, cleaning and unloading processes of the substrate are performed automatically, which is simple and convenient to operate; on the other hand, the side edge alignment type layering is performed with one side as the fence, the fence plays a certain limiting and guiding role during the descending of the collecting platform to reduce the deviation of the substrate during the descending process, in addition, the automatic counting of the substrate layering can be performed during the descending of the collecting platform, and the lifting can be intelligently started and stopped under the assistance of the upper and lower limiting; thirdly, the strip brushes are formed in multiple groups, each group has two strip brushes arranged symmetrically above and below, and the impurities on the upper and lower surfaces of the substrate are brushed away, meanwhile, the multiple spraying heads are uniformly distributed along the length direction of the connecting pipe, and the vertical distance between the bottom of the spraying hose and the substrate can be adjusted up and down as needed, the solvent flow formed by the spraying hose is consistent with the direction of the substrate, in short, it is convenient for the transmission of the substrate, and the roller brushes are always in a wet state to ensure the uniformity of the brushing and provide favorable conditions for forming the solidified resin layer; fourthly, the positioning fence has two functions: ① reference function, which aligns the multiple stacked substrates with the side edge where the positioning fence is located; ② limiting and guiding role during the descending of the collecting platform to reduce the deviation of the substrate during the descending process, at the same time, considering the possible deviation of the substrate during the translation process, which may affect the neatness of the stacked substrates, when the substrate is conveyed to the connecting roller, the connecting rollers located on both sides are respectively rolled and cooperated on the opposite sides of the substrate. Through the setting of the connecting rollers on both sides, the deviation of the substrate during the movement process is limited, thereby improving the neatness of the stacked substrates; fifthly, the layout of the two connecting rollers is very simple, the two connecting rollers on both sides can be symmetrically arranged or staggered, thereby improving the neatness of the stacked substrates; sixthly, when substrates of different thicknesses are processed, only the corresponding scale ruler needs to be replaced to realize the counting of the substrate, at the same time, when the pointer contacts the upper limit contact switch, the driving mechanism stops the upward movement, and when the pointer contacts the lower limit contact switch, the driving mechanism stops the downward movement; seventhly, the drying section mainly uses heating rods to heat the substrate, and the air drying section mainly uses fans to form a rapid airflow to carry away the heat during drying, thereby forming a solidified resin layer on the surface of the substrate.

[0090] The above detailed description of the application is intended to be illustrative and not limiting. Other alternatives will be apparent to those of skill in the art without departing from the spirit of the application.
