[0042] Reference Figure 1 A slab slab mesh laying machine includes a frame 100, a roll material frame 300, a mesh laying and cutting mechanism 400, and a mesh pressing mechanism 500. A feeding roller group 200 is provided on the frame 100. The roll material frame 300 is fixed on the frame 100 and is used to hold the mesh roll. The mesh laying and cutting mechanism 400 is located above the frame 100 and adjacent to the roll material frame 300. The mesh laying and cutting mechanism 400 is used to unfold the mesh roll on the roll material frame 300 and lay it on the back of the slab. The mesh pressing mechanism 500 is fixed above the frame 100 and located at the discharge end of the feeding roller group 200. The mesh pressing mechanism 500 is used to press the mesh tightly onto the back of the slab.

[0043] During operation, the wire mesh roll is placed on the roll frame 300. The rock slab with adhesive on the back is conveyed to the wire mesh laying and cutting mechanism 400 by the feeding roller group 200. The wire mesh laying and cutting mechanism 400 pulls the wire mesh out of the roll and sends it above the rock slab. As the rock slab moves, the wire mesh is gradually laid on the back of the rock slab and cut according to the length of the rock slab. The rock slab continues to be conveyed to the wire mesh pressing mechanism 500 by the feeding roller group 200. The wire mesh pressing mechanism 500 presses the wire mesh tightly against the back of the rock slab, which solves the problem of low efficiency of the existing manual wire mesh application, improves product quality, and reduces production costs.

[0044] Reference Figure 2 The roll frame 300 includes a support 310, a roller seat 320, and a fixed seat 330. Two supports 310 are used, and the two supports 310 are fixed to the top of the frame 100, with the feeding roller group 200 located between the two supports 310. The roller seat 320 is fixed to the top of the support 310, and the fixed seat 330 is rotatably mounted on the roller seat 320. The fixed seat 330 is used to press the roll 340 onto the roller seat 320, and the roll 340 rotates between the roller seat 320 and the fixed seat 330. The roll 340 is used to thread the wire mesh roll.

[0045] Reference Figure 3 , 4 To ensure smooth rotation of the roll 340 between the roller seat 320 and the fixed seat 330, a lower arc-shaped groove 321 is provided on the top of the roller seat 320, and an upper arc-shaped groove 333 is provided on the bottom of the fixed seat 330. The upper arc-shaped groove 333 and the lower arc-shaped groove 321 are used to accommodate the roll 340, and the roller seat 320 and the fixed seat 330 can clamp the roll 340.

[0046] To further improve the clamping of the roller seat 320 and the fixed seat 330 on the roll 340, a connecting ear plate 331 is provided at one end of the fixed seat 330 in the vertical direction. The connecting ear plate 331 is rotatably connected to the roller seat 320. When picking up and putting down the wire mesh roll, the fixed seat 330 is flipped over to expose the top of the roller seat 320. The roll 340 is placed in the lower arc-shaped groove 321. The fixed seat 330 is flipped over again to press the fixed seat 330 on the roller seat 320, so that the upper arc-shaped groove 333 and the lower arc-shaped groove 321 are combined and the roll 340 is accommodated therein.

[0047] Reference Figure 3 , 4To prevent the fixed seat 330 from accidentally flipping open due to shaking or other reasons during operation, which could cause the roll 340 to come out of the lower arc-shaped groove 321, a fixed ear plate 332 is provided horizontally at the other end of the fixed seat 330. The fixed ear plate 332 has a notch 301 in the center. A hinged screw 350 is rotatably mounted on the roller seat 320. When the hinged screw 350 is rotated to the vertical position, the hinged screw 350 enters the notch 301 and tightens the locking nut 360 mounted on the hinged screw 350, so that the locking nut 360 presses the fixed ear plate 332, thereby making the connection between the fixed seat 330 and the roller seat 320 tight. When the roll 340 needs to be removed, the locking nut 360 is loosened and the hinged screw 350 is dislodged from the notch 301, so that the fixed seat 330 can be flipped back.

[0048] Reference Figure 5 The netting laying and cutting mechanism 400 includes a netting spreading roller group 410, a clamping roller group 420, and a netting cutting assembly 430. The netting material passes through the netting spreading roller group 410, the clamping roller group 420, and the netting cutting assembly 430 in sequence. After the netting material is spread out by the netting spreading roller group 410, it is clamped and conveyed by the clamping roller group 420. The netting cutting assembly 430 is used to cut the netting material.

[0049] Reference Figure 6 , 7 The spreading roller group 410 includes a first spreading roller 411, a second spreading roller 412, and a third spreading roller 413 located on the same horizontal plane. The net material passes around the first spreading roller 411, the second spreading roller 412, and the third spreading roller 413 in sequence, so that the net material is spread out.

[0050] Reference Figure 6 , 7 The pinch roller assembly 420 includes a pressure roller 421 and a bottom roller 422. The pressure roller 421 is rotatably mounted above the bottom roller 422. The pressure roller 421 and the bottom roller 422 clamp the mesh material. The bottom roller 422 is driven to rotate by a first rotary drive member. The mesh material moves as the bottom roller 422 rotates by utilizing the friction between the bottom roller 422 and the mesh material.

[0051] Reference Figure 8 The wire mesh cutting assembly 430 includes a blade holder 431, a crank connecting rod 432, and a drive shaft 433. The blade holder 431 is used to fix and install the cutter, with the blade facing downward. Lifting connecting rods 434 are connected to both ends of the blade holder 431. The lifting connecting rods 434 are rotatably connected to the crank connecting rod 432. The crank connecting rod 432 is provided with an eccentric hole 4321, and the drive shaft 433 is inserted into the eccentric hole 4321. During cutting, the drive shaft 433 is driven to rotate by a second rotary drive component, causing the crank connecting rod 432 to rotate eccentrically. At the same time, during the eccentric rotation of the crank connecting rod 432, the lifting connecting rod 434 is pulled downward by the crank connecting rod 432, causing the blade holder 431 to move downward, so that the cutter cuts the wire mesh.

[0052] Reference Figure 5 The discharge end of the wire mesh cutting assembly 430 is connected to a discharge guide plate 440, so that the wire mesh enters the discharge guide plate 440 after passing through the wire mesh cutting assembly 430. At the same time, the plate head pressure roller assembly 450 presses the wire mesh that is discharged through the discharge guide plate 440, so that the wire mesh is pressed vertically towards the rock slab, so that the wire mesh is in a taut and unfolded state, so as to ensure that the wire mesh will not wrinkle when covering and pasting, which would prevent the wire mesh from being completely covered and pasted on the back of the rock slab, thus affecting the strength of the rock slab.

[0053] Reference Figure 9 The plate head pressure roller assembly 450 includes a cloth pressure roller 451 and a pressure roller adjustment assembly 452. The pressure roller adjustment assembly 452 is connected to both ends of the axle of the cloth pressure roller 451. The pressure roller adjustment assembly 452 is fixed to the top of the frame 100. The height of the cloth pressure roller 451 is adjusted by adjusting the pressure roller adjustment assembly 452, thereby adjusting the pressure of the cloth pressure roller 451 on the rock plate.

[0054] Reference Figure 9 Specifically, the pressure roller adjustment assembly 452 includes a slide cylinder 4521, a moving plate 4522, a mounting plate 4523, a push-pull cylinder 4524, a pressure roller guide rod 4526, and a pressure roller connecting block 4527. The slide cylinder 4521 is fixed on the base 4528, and the base 4528 is fixed on the frame 100. The moving plate 4522 is connected to the slide cylinder 4521, and a guide plate 4525 is connected between the moving plates 4522. The mounting plate 4523 is slidably mounted on the slide cylinder 4521. On the movable plate 4522, there is a mounting plate 4523 and a push-pull cylinder 4524. The push-pull cylinder 4524 is fixed to the top of the movable plate 4522 and is used to push and pull the mounting plate 4523. An adjusting bushing 4529 is fixed on the mounting plate 4523. The pressure roller guide rod 4526 is movably installed in the adjusting bushing 4529. The pressure roller guide rod 4526 is connected to the pressure roller connecting block 4527. The pressure roller connecting block 4527 is connected to the wheel axle of the fabric pressure roller 451.

[0055] To ensure that the mesh material is pressed firmly onto the rock slab by the fabric pressure roller 451 and simultaneously pressed against the guide film plate 4525, guaranteeing that the mesh material is pressed firmly onto the rock slab in a vertical state, the push-pull cylinder 4524 pushes the fabric pressure roller 451 obliquely downwards, so that the fabric pressure roller 451 and the guide film plate 4525, as well as the fabric pressure roller 451 and the rock slab, are both kept in a pressed state.

[0056] A spring 45210 is fitted on the pressure roller guide rod 4526. The spring 45210 is located between the adjusting bushing 4529 and the pressure roller connecting block 4527. The elastic force of the spring 45210 keeps the fabric pressure roller 451 pressed against the mesh material.

[0057] Reference Figure 10The pressing mechanism 500 includes a pressing roller 510, a bearing seat 520, a mounting frame 530, and a height adjustment drive 540. The pressing roller 510 is located above the feeding roller group 200. Both ends of the roller shaft of the pressing roller 510 are rotatably mounted on the bearing seat 520. The bearing seat 520 is lifted and lowered on the mounting frame 530. The height adjustment drive 540 is connected to the bearing seat 520 and fixed to the top of the mounting frame 530. The height adjustment drive 540 is used to lift and move the bearing seat 520 to adjust the height of the pressing roller 510 to adapt to different specifications of rock slabs. While maintaining the pressing state of the pressing roller 510 on the rock slab, it does not affect the movement of the pressing roller 510 on the rock slab, so that the mesh material can be tightly attached to the back of the rock slab.

[0058] Reference Figure 11 To adjust the position of the slab on the feeding roller group 200, the centering mechanism 600 is used to make the centerline of the slab coincide with the centerline of the feeding roller group 200, so as to ensure the accurate position of the mesh covering and pasting, and avoid the mesh covering and pasting of the slab in a skewed state, which would reduce the quality of production.

[0059] Specifically, the centering mechanism 600 includes a lifting mechanism 610 and a push rod assembly 620. The lifting mechanism 610 is located below the feeding roller group 200 and is used to lift the rock slab placed on the feeding roller group 200. The push rod assembly 620 is used to push the lifted rock slab to adjust its position.

[0060] Reference Figure 12 , 13 The lifting mechanism 610 includes a frame 611, a roller assembly 612, a lifting cylinder 613, a connecting plate 614, a connecting rod 615, a rotating shaft 616, and a connecting rod 617. Multiple roller assemblies 612 are arranged and installed on the frame 611. The rock slab moves left and right using multiple roller assemblies 612. Four lifting cylinders 613 are used and fixed on the frame 100. The lifting cylinders 613 are connected to the bottom of the corner of the frame 611. The four lifting cylinders 613 lift the frame 611 simultaneously.

[0061] To ensure the synchronization of the lifting of the frame 611, four connecting plates 614 are used. The four connecting plates 614 are arranged in a rectangle and are connected to the frame 611. A rotating shaft 616 is connected between two connecting plates 614 on the same wide side, and a connecting rod 617 is rotatably connected between two connecting plates 614 on the same long side. A bearing seat 520 is mounted on the rotating shaft 616. The bearing seat 520 and the lifting cylinder 613 are both fixed on the frame 100.

[0062] Reference Figure 15Specifically, the connecting plate 614 is provided with a first mounting position 6141, a second mounting position 6142, and a third mounting position 6143. One end of the connecting rod 615 is rotatably mounted on the first mounting position 6141, and the other end of the connecting rod 615 is rotatably connected to the frame 611. The second mounting position 6142 is connected to the end of the rotating shaft 616, and the third mounting position 6143 is rotatably connected to the end of the connecting rod 617.

[0063] Reference Figure 13 , 14 As shown, when the lifting cylinder 613 raises the frame 611, the frame 611 pulls the connecting plate 614 through the connecting rod 615. The two connecting plates 614 located on the same wide side rotate synchronously around the rotation axis 616 during the pulling process; at the same time, the two connecting plates 614 located on the same long side rotate synchronously using the connecting rod 617 to assist the lifting of the frame 611 and increase the support force on the rock slab.

[0064] Reference Figure 13 , 14 As shown, two sets of push rod assemblies 620 are used, and the two sets of push rod assemblies 620 are located on the left and right sides of the lifting mechanism 610, respectively. The push rod assembly 620 includes a fixed push rod 621, a movable push rod 622, and a centering cylinder 623. Centering guide wheels 624 are arranged at the bottom of both the fixed push rod 621 and the movable push rod 622. The centering guide wheels 624 contact the side of the rock slab, which facilitates the adjustment and movement of the rock slab during the centering process. The centering cylinder 623 is connected to the movable push rod 622 and is used to push and pull the movable push rod 622, so that the movable push rod 622 moves toward or away from the fixed push rod 621.

[0065] A support block is fixed to the bottom of the fixed push rod 621. The centering cylinder 623 is fixed to the fixed plate. The fixed plate and the support block are slidably mounted on the guide rail. The fixed plate and the support block are respectively connected to a screw nut. The two screw nuts are threaded onto a screw. A coupling is installed between the two screws. By rotating one of the screws, the two screw nuts move in opposite directions, thereby adjusting the distance between the moving push rod 622 and the fixed push rod 621 at the end of the stroke pushed by the center cylinder 623, so that the distance can be adapted to rock slabs of different specifications.

[0066] The slab is conveyed and stopped above the lifting mechanism 610. The lifting cylinder 613 lifts the frame 611 upward. As the frame 611 is lifted, the slab is placed on multiple sets of rollers 612. Finally, the slab is lifted to the horizontal plane where the push rod assembly 620 is located. The centering cylinder 623 in the two sets of push rod assemblies 620 pushes and pulls the push rod 622, causing the moving push rod 622 to move towards the fixed push rod 621, so that the slab is pushed towards the fixed push rod 621, thereby making the centerline of the slab coincide with the centerline of the conveying roller assembly 200, and realizing the centering of the slab.

[0067] After the centering action is completed, the moving push rod 622 is pulled by the cylinder 623, releasing the clamping state between the passive push rod 622 and the fixed push rod 621. The lifting cylinder 613 pulls the frame 611 down, causing the rock slab to descend and be placed on the feeding roller group 200. The feeding roller group 200 then begins to transport the rock slab.
