[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a quick-applying structure is installed on the top of the support leg 20 to quickly apply glue to the wall surface of the insulation board.

The connecting rod 23 is fixedly connected to one side wall of the main side plate 21. The secondary side plate 24 is also fixedly connected to the support leg 20. At the top, the secondary slide groove 25 is formed on the wall of the secondary side plate 24. The main slide block 34 is fixedly connected to the rear wall of the slide frame 30, and the secondary slide block 35 is also fixedly connected to the rear wall of the slide frame 30. The secondary slide block 35 and the main slide block 34 are symmetrical on both sides of the rear wall of the slide frame 30. The baffle 36 is fixedly connected to the top of the slide frame 30 on the same side as the main slide block 34. The bottom of the main side plate 21 and the secondary side plate 24 are respectively provided with the same support legs 20. The connecting rod 23 is a rectangular rod. The two ends of the connecting rod 23 are respectively connected to the side walls of the secondary side plate 24 and the main side plate 21. Multiple identical connecting rods 23 are evenly arranged between the secondary side plate 24 and the main side plate 21. The lowest connecting rod 23 is located at the bottom middle section. A rectangular plate is fixedly connected to the main side plate 21, which is an L-shaped rod. Main slide grooves 22 are respectively opened on the front and side walls of the main side plate 21. A slide frame 30 also has another main slide 34 on the side wall in the same direction as the main slide 34.

On one side wall of 42, roller 44 is rotatably connected to the rear wall of connecting plate 43, slide rail 40 is fixedly connected to the top side wall of slide frame 30, limiting groove 41 is opened through the wall of slide rail 40, reciprocating block 42 is slidably connected in limiting groove 41, lifting wheel 27 is gear-shaped, lifting rod 32 is rectangular plate, lifting rod 32 has teeth on the wall facing the lifting wheel 27 that can mesh with the wall of lifting wheel 27, limiting groove 41 can adapt to the sliding of reciprocating block 42 of I-shaped block, teeth are opened on one side wall of slide rail 40, roller 44 is cylindrical, and the arc surface of roller 44 has the same teeth that can mesh with the teeth on the wall of slide rail 40;

[0031] In practical use, motors are installed on the rectangular plates at the bottom of the connecting plate 43 and the connecting rod 23, respectively. All motors are controlled and turned on by their respective power supplies. When installing the insulation board, the motor at the bottom of the connecting rod 23 is turned on to drive the lifting wheel 27 to rotate. When the lifting wheel 27 rotates, it will engage with the wall of the lifting rod 32, causing the lifting rod 32 to move up and down. The lifting rod 32 can drive the sliding frame 30 and the structure of the sliding frame 30 wall to move up and down synchronously. After the sliding frame 30 drives the alignment plate 33 to rise and fall to the required height, the rotation of the lifting wheel 27 is stopped. Then, the cut insulation board is pushed from the gap between the slide rail 40 and the secondary side plate 24 toward the baffle 36. When passing through the 24th section, turn on the motor on the wall of the connecting plate 43. The motor can drive the roller 44 to rotate. The roller 44 can mesh with the wall of the slide rail 40, which drives the reciprocating block 42 to slide vertically up and down along the limiting groove 41. The reciprocating block 42 can drive the storage box 45, the nozzle 46 and the connecting plate 43 to move synchronously. At this time, the nozzle 46 can spray the glue in the cavity of the storage box 45 from the opening of the nozzle 46 towards the wall of the insulation board. After the insulation board has completely passed through the slide rail 40 and the secondary side plate 24, stop the nozzle 46 from spraying and the roller 44 from rotating. At this time, align the insulation board with the required installation position, and then manually pass it through the adjacent connecting rod 23 and push the insulation board onto the wall to complete the installation.

[0032] In summary, by setting up a quick-applying structure, adhesive can be quickly applied to the wall surface of the insulation board. The quick-applying structure uses a reciprocating block 42 that moves up and down to drive the nozzle 46 to spray the wall surface of the insulation board repeatedly. After spraying, the sprayed insulation board can be directly aligned with the required installation position for installation. Therefore, this solution has the advantages of quick installation and ease of installation for workers.

[0033] like Figure 1 and Figure 5 As shown, the wall of the slide rail 40 is provided with a limiting structure, which includes a locking groove 50, an adjusting plate 51, a through plate 52, a bolt 53, and a limiting plate 54. The locking groove 50 is opened on one side wall of the slide rail 40. The adjusting plate 51 is slidably connected in the limiting groove 41. The through plate 52 is fixedly connected to one side wall of the adjusting plate 51. The bolt 53 is threadedly connected to the wall of the through plate 52. The limiting plate 54 is fixedly connected to the rear wall of the adjusting plate 51. The adjusting plate 51 is also an I-shaped plate. The through plate 52 can be connected to both ends of one side of the adjusting plate 51 respectively. The bolt 53 can pass through the through plate 52 and enter the locking groove 50. The limiting plate 54 is a rectangular plate. The rear wall of the limiting plate 54 can contact the front wall of the secondary side plate 24.

[0034] In practical use, unscrew the end of the bolt 53 from the locking groove 50, and then manually control the adjusting plate 51 to slide along the limiting groove 41. When the adjusting plate 51 drives the limiting plate 54 to move to be flush with the top of the insulation board to be installed, the bolt 53 can be screwed into the locking groove 50 to make the slide rail 40 wall abut against it, thereby fixing the position of the adjusting plate 51. After the roller 44 drives the reciprocating block 42 to move to contact the bottom of the adjusting plate 51, it will drive the reciprocating block 42 to move downward.

[0035] In summary, by setting a limiting structure, the insulation board can be prevented from shifting when it moves on the wall of the sliding frame 30, and the reciprocating block 42 can also be limited to prevent the reciprocating block 42 from driving the nozzle 46 to a blank area and wasting glue.

[0036] Working principle: Motors are installed on the rectangular plates at the bottom of connecting plate 43 and connecting rod 23, respectively. All motors are controlled by their respective power supplies. When installing the insulation board, the motor at the bottom of connecting rod 23 is first turned on to drive the lifting wheel 27 to rotate. When the lifting wheel 27 rotates, it engages with the wall of lifting rod 32, causing lifting rod 32 to move up and down. Lifting rod 32 can drive the sliding frame 30 and the structure of the sliding frame 30 wall to move up and down synchronously. After the sliding frame 30 drives the alignment plate 33 to rise and fall to the required height, the rotation of lifting wheel 27 is stopped. Then, the cut insulation board is pushed from the gap between the slide rail 40 and the secondary side plate 24 towards the baffle 36. When passing through the four sections, turn on the motor on the wall of the connecting plate 43. The motor can drive the roller 44 to rotate. The roller 44 can engage with the wall of the slide rail 40, which drives the reciprocating block 42 to slide vertically up and down along the limiting groove 41. The reciprocating block 42 can drive the storage box 45, the nozzle 46 and the connecting plate 43 to move synchronously. At this time, the nozzle 46 can spray the glue in the cavity of the storage box 45 from the opening of the nozzle 46 towards the wall of the insulation board. After the insulation board has completely passed through the slide rail 40 and the secondary side plate 24, stop the nozzle 46 from spraying and the roller 44 from rotating. At this time, align the insulation board with the required installation position, and then manually pass it through the adjacent connecting rod 23 and push the insulation board onto the wall to complete the installation.
