As shown in fig. 1, the upper roller brush type automatic cleaning machine for floor molding of the present embodiment includes a loading unit a, a brush roller type cleaning mechanism B, a receiving unit C, a drying unit D, and a conveying unit E.

Specifically, the feeding unit a is shown in fig. 2 and 3, and is used for horizontally pushing the laminated substrate B to the brush roller type cleaning mechanism B piece by piece.

In this example, the loading unit a includes a carrying platform 1 for placing the laminated substrate B, a lifting mechanism 2 for driving the carrying platform 1 to lift upwards gradually, a pushing mechanism 3 disposed on one side of the carrying platform 1, and a counting mechanism 4 for counting the number of blocks of the substrate B sent into the brush roller type cleaning mechanism B, where the lifting mechanism 2 has a height equal to the thickness of one substrate B each time, and the pushing mechanism 3 pushes the substrate B with an automatic upward position for repairing to the brush roller type cleaning mechanism B.

Specifically, the lifting mechanism 2 includes a base 20, a scissor support arm 21 disposed between the base 20 and the load-bearing platform 1, and a driving assembly (not shown) for driving the scissor support arm 21 to relatively open or close. In short, the lifting mechanism 2 corresponds to a scissor lift, the working principle of which is exactly the same as that of the scissor lift and which will not be described in detail here.

However, the orthographic projection area of the carrying platform 1 of the present application on the base 20 is smaller than the upper surface area of the base 20.

The pushing mechanism 3 comprises a positioning seat 30 positioned at one side of the bearing platform 1 far away from the brush roller type cleaning mechanism B, a pushing rod piece 31 which can move along the horizontal direction and is arranged on the positioning seat 30, and a driving piece 32 for driving the pushing rod piece 31 to reciprocate, wherein the pushing rod piece 31 is aligned with the brush roller type cleaning mechanism B, and the substrate B which is automatically complemented upwards is pushed to the brush roller type cleaning mechanism B piece by piece in the reciprocating motion.

In order to ensure the ejection effect, in this example, a leaning grid plate A5 is further provided on the side of the carrying platform 1, and the laminated substrate b leans against the leaning grid plate A5 from one side. The leaning grid plate A5 can be one piece or two pieces,

specifically, the leaning grid plates A5 are positioned at two opposite sides of the pushing direction of the substrate b. The pushing of the substrate b is more stable under the action of the leaning grid plate A5.

At the same time, it is also important that the ejector pin 31 is in contact with the substrate b, either too much contact or too little contact affects the pushing of the substrate b, and then the effective contact height is 0.5 to 1 times the thickness of the substrate, wherein the effective contact height is calculated from the top edge of the substrate downwards.

In this example, the effective contact height of the pushing end of the ejector pin 31 with the substrate b is 0.6 times the thickness of the substrate, that is, the distance between the bottom of the ejector pin 31 and the next substrate b is 0.4 times the thickness of the substrate b.

Specifically, the positioning seat 30 includes a positioning rod 300 aligned with the middle of the laminated substrate, and the ejector rod 31 is movably disposed at a position where the positioning rod 300 is aligned with the brush roller type cleaning mechanism B.

The ejector rod member 31 includes an ejector rod 310 extending in a horizontal direction, and limit modules 311 provided at both ends of the ejector rod 310, and when the driving member 32 contacts any one of the limit modules 311, the driving member 32 moves reversely to realize the reciprocating movement of the ejector rod member 31.

The driving member 32 includes a driving gear 32a formed at an upper portion of the push rod 310 along a length direction of the push rod 310, and a driving gear 32b provided at the positioning rod 300 to be engaged with the driving gear 32 a.

In this example, there are two driving gears 32b, which are respectively disposed at opposite sides of the positioning rod 300. Therefore, the reciprocating speed of the jack 310 is effectively increased under the synchronous driving of the two driving gears, and the jack 310 is also made to move more smoothly.

As for the transmission mode, a driving motor is provided on the positioning rod 300, and then the driving motor and the driving gear 32b are synchronously connected by adopting a belt wheel transmission mode, wherein the driving motor is positioned at the top of the driving gear 32b, the center of the driving gear 32b and the center of the output end of the driving motor form an equilateral triangle, and meanwhile, the driving motor has a forward and reverse rotation mode.

Meanwhile, tooth grooves 311a matched with the driving gear 32b are further formed in the inner side of the limiting module 311, and when the driving gear 32b is meshed with one tooth groove 311a, the driving motor reversely rotates to realize reciprocating motion.

Then, considering the problem of occupying space, the ejector rod 310 is arranged into a plurality of sections to be spliced and butted to form a rod piece which is horizontally arranged, and the limiting modules 311 are arranged at two end parts of the rod piece. The multi-section arrangement aims that the push rod is folded by rotation of the push rod under the non-working state, so that the occupied space of the push rod is reduced.

The counting mechanism 4 comprises a graduated scale 40 formed on the positioning rod 300 and taking 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 graduated scale. The number of the feed blocks is obtained by subtracting the reference value from the position value pointed by the pointer, so that the control is very convenient.

Further, the scale 40 is detachably positioned on the positioning rod 300, and is also capable of being set up in a vertically adjustable manner along the height direction of the positioning rod 300. When the substrates with different thicknesses are processed, the counting of the substrates can be realized only by replacing the corresponding graduated scales.

Meanwhile, the counting mechanism 4 further comprises an intelligent controller 42 communicated with the lifting mechanism 2, the intelligent controller 42 comprises contact switches k respectively arranged at the upper limit and the lower limit of the graduated scale 40, when the pointer 41 contacts with the contact switch at the upper limit or the lower limit of the graduated scale 40, a closed circuit is formed, and the lifting mechanism stops moving. In short, after the pointer contacts with the upper limit contact switch, the lifting mechanism stops the lifting movement; when the pointer contacts with the contact switch of the lower limit, the lifting mechanism stops the descending movement.

Referring to fig. 4, in this embodiment, the brush roll type cleaning mechanism B includes a first cleaning unit B1 for removing impurities from the surface of the substrate B, and a second cleaning unit B2 that is in butt joint with the first cleaning unit B1 and cleans the glued surface of the substrate B with a cleaning solvent.

The first cleaning unit B1 comprises a locating frame B10 and a strip brush B11 arranged on the locating frame B10, wherein the extending direction of the strip brush B11 is intersected with the translation direction of the substrate B, and the bristles of the strip brush B11 brush impurities on the surface of the substrate B.

The strip brushes B11 form a plurality of groups, two strip brushes B11 in each group are arranged symmetrically up and down, and sundries on the upper surface and the lower surface of the substrate B are brushed off. The strip brush B11 is also a direct outsourcing product, and the specific structure thereof is not repeated here.

The second cleaning unit B2 includes a cleaning tank B20, a brush roller B23 positioned in the cleaning tank B20 and above the substrate B transfer roller, and a cleaning liquid spray assembly B24 positioned between the brush roller B23 and the first cleaning unit B1.

As for the structure of the brush roller B23, the present inventors directly outsourced, and belongs to a conventional product, and the specific structure thereof is not described in detail herein.

However, in this example, the brush roller B23 is provided to extend horizontally in a direction perpendicular to the translation direction of the substrate B, and is provided to rotate around its own axis line.

The spray assembly B24 is disposed near the brush roll B23, and includes a passage pipe 240 positioned at the right side of the brush roll B23 and extending along the length direction of the brush roll B23, a plurality of spray headers 241 communicated with the passage pipe 240 and disposed side by side, a spray hose 242 connected to the bottom of each spray header 241, and a water pump 243 and a connection pipe 244 pumping the cleaning solvent to the passage pipe 240, wherein the bottom of the spray hose 242 is inclined toward the brush roll B23 from top to bottom, and the cleaning solvent is flushed from the bottom of the spray hose 242 toward the surface of the substrate B.

For uniformity of spraying, in this example, the plurality of spray heads 241 are uniformly distributed along the length direction of the channel pipe 240, and the vertical distance between the bottom of the spray hose 242 and the substrate b is adjusted up and down according to the requirement, however, the solvent flow direction formed by the spray hose 242 is consistent with the trend of the substrate, so that on one hand, the substrate is convenient to drive; on the other hand, ensuring that the brush roller B23 is always in a wet state, thereby ensuring uniformity of brushing, provides an advantage in forming a cured resin layer.

In addition, in this example, the cleaning mechanism further includes a conveying roller B3 provided at the in-out end portion of the second cleaning unit B2 and disposed flush therewith. The transfer of the substrate is effected by the conveyance roller B3 abutting.

In short, after the impurities on the surface of the substrate are primarily brushed off, the brush rolls of the two cleaning solutions are used for ensuring that the surface of the substrate is free of impurities and a cleaning solvent layer (containing components including resin and colorless and volatile liquid) can be formed, and a solidified resin layer is formed after drying, so that convenience is brought to subsequent skin layer gluing, and the peeling strength of the skin layer can be improved.

In this example, the drying unit D mainly includes two parts of a drying section D2 and an air drying section D1, where the drying section D2 mainly uses a heating rod D20 to heat the substrate b; as for the air-drying section D1, a fast-flowing air flow is formed by the fan D10, and the like, heat generated during drying is taken away, so that a resin cured layer is formed on the surface of the substrate b.

Meanwhile, the transfer unit E, which mainly includes E1 moving rollers for receiving the substrate b, or pressing rollers, in the above-described respective units, is also a conventional arrangement, and will not be described in detail herein.

As shown in fig. 5 to 7, the receiving unit in this example stacks and collects the substrates b transferred from the drying unit D.

Specifically, the material receiving unit comprises a material receiving frame C1, a material receiving platform C2 for bearing the substrate b, a driving mechanism C3 arranged on the material receiving frame C1 and used for driving the material receiving platform C2 to move downwards gradually, a counting assembly C4 used for counting the number of stacked blocks of the substrate b, and a connection mechanism 5 arranged on the material receiving frame C1 and used for connecting the substrate b horizontally transferred from the drying unit D, wherein the height of each descending of the driving mechanism C3 is equal to the thickness of one substrate b.

In this example, the drying unit D is located on the right side, the receiving unit is located on the left side, the substrate b translates along the length direction of the substrate b from the right side to the left side, and stacking and receiving are performed, and after each substrate b is collected, the receiving platform C2 descends once until stacking of a plurality of substrates b is completed.

However, the uniformity of the lamination is determined entirely by the performance of the docking mechanism 5, and in this example, the following technical means are employed to achieve lamination with high uniformity.

The docking mechanism 5 includes a docking frame 50 positioned on the material receiving frame C1 and having a positioning fence 50a, a docking roller 51 positioned in front of the positioning fence 50a and used for shifting the substrate b transferred by the drying unit D toward the positioning fence 50a, and a driving member (not shown in the drawing) for driving the docking roller 51 to rotate, wherein the positioning fence 50a is positioned above the left side of the material receiving platform C2, and when the side edge of the substrate b abuts against the positioning fence 50a, the docking roller 51 stops moving, and the driving mechanism C3 drives the material receiving platform C2 to descend once.

To further explain the above structure and principle, in this example, the substrate b is rectangular and translates above the receiving platform C2 along the length direction, and the positioning fence 50a extends along the width direction of the substrate b.

Meanwhile, the docking roller 51 coincides with the extending direction of the positioning fence 50 a.

Then, the bottom surface of the positioning fence 50a is parallel to the upper surface of the receiving platform C2, and the vertical distance between the bottom surface of the positioning fence 50a and the upper surface of the receiving platform C2 is an integer multiple of the thickness of the substrate b.

In this example, the positioning fence 50a functions in two ways: 1. with reference to the action of the datum, aligning the plurality of laminated substrates to position the side edge of the leaning gate; 2. plays a certain limiting and guiding role when the material receiving platform descends, and reduces the deviation of the substrate caused by the descending process.

Meanwhile, considering the possible deviation of the substrate b during the translation process, and thus the uniformity of the laminated substrate, the docking mechanism 5 in this example further includes an extension rod 52 extending horizontally from both ends of the docking frame 50 to the molding apparatus, and a docking roller 53 disposed on the extension rod 52 and rotating around the axis in the vertical direction, wherein the docking roller 53 is suspended above the side of the receiving platform C2, and when the substrate b is transferred to the docking roller 51, the docking rollers 53 on both sides are respectively engaged on opposite sides of the substrate b in a rolling manner. By providing the two side guide rollers 53, the deviation of the substrates b during the movement is restricted, and the uniformity of the substrates after lamination is improved.

Specifically, there are two receiving rollers 53 on each side extension rod 52, and the roller surfaces on the same side receiving rollers 53 contacting the side of the substrate b are arranged flush.

As for the layout of the two receiving rollers 53, the two receiving rollers 53 on both sides may be symmetrically arranged or may be offset from each other.

In this example, the receiving rollers 53 on two sides are symmetrically arranged, then the receiving rollers 53 are hung on the inner side of the extension rod 52 through the receiving rods 54, and the receiving rollers 53 comprise roller bodies 531 rotatably arranged on the lower parts of the receiving rods 54 through bearings 530, and anti-slip roller sleeves 532 sleeved on the peripheries of the roller bodies 531.

The material collecting frame C1 comprises a base 10 and a stand column 11 positioned on one side of the base 10 principle forming equipment, the connection frame 50 is positioned at the position where the stand column 11 is aligned with the discharge hole of the drying unit D, and the connection frame 50 can be arranged on the stand column 11 in a moving and adjusting mode along the height direction of the stand column 11.

The counting assembly C4 includes a graduated scale 40 formed on the upright 11 and having a thickness of one unit per substrate b, and a pointer 41 disposed on the receiving platform C2 corresponding to the upright and pointing to the graduated scale 40.

The scale 40 is detachably positioned on the column 11, and is also capable of being set up in a vertically adjustable manner along the column 11. When the substrates b with different thicknesses are processed, the counting of the substrates can be realized only by replacing the corresponding graduated scale 40.

Further, the counting assembly C4 further includes an intelligent controller 42 in communication with the driving mechanism C3, the intelligent controller 42 includes contact switches k respectively disposed at an upper limit and a lower limit of the graduated scale 40, and when the pointer 41 contacts with the contact switch k at the upper limit or the lower limit of the graduated scale 40, a closed circuit is formed, and the driving mechanism C3 stops moving. In short, after the pointer 41 is in contact with the upper limit contact switch k, the driving mechanism C3 stops the ascending motion; when the pointer 41 contacts the contact switch k of the lower limit, the driving mechanism C3 stops the descending movement.

In addition, for the driving mechanism C3 including the scissor type supporting arm C30 and a hydraulic cylinder (not shown in the figure) for driving the scissor type supporting arm C30 to be unfolded or folded, the specific principle is similar to that of an elevator (or an elevating platform), and the driving mechanism C3 can be lowered and lifted upwards, which belongs to a conventional design in the art, and will not be described in detail herein.

The present application has been described in detail with the purpose of enabling those skilled in the art to understand the contents of the present application and to implement the same, but not to limit the scope of the present application, and all equivalent changes or modifications made according to the spirit of the present application should be included in the scope of the present application.
