Description

Technical Field

[0001] This utility model belongs to the field of artificial board processing technology, and specifically relates to an anti-deformation device for artificial boards during the cooling process of the flipping wheel. Background Technology

[0002] During the production of engineered wood products such as MDF or particleboard, the boards exiting the hot press need to be cooled to lower their temperature during the curing process and prevent excessive strength degradation. This cooling process utilizes a rotating cooling system with a tumbling plate. The tumbling plate rotates along its axis, increasing the board's exposure time to air and thus achieving cooling. In the production of thin boards, due to the high production line speed, a large number of boards are produced per unit time. To increase efficiency, two or more boards are often cooled using the same tumbling plate grid. However, this process can lead to board deformation.

[0003] The specific cause is that, in order to increase the dimensional adaptability of boards and reduce the failure rate, the tipping roller was designed so that after the board enters the tipping roller, the edge of the board does not fit against the bottom of the tipping roller, but leaves a certain space. As the board rotates upward with the tipping roller support, it automatically falls to the bottom of the tipping roller due to gravity. When there is only one board between the tipping roller supports, there is no problem. However, when there are multiple boards between the tipping roller supports, the upper board will fall to the bottom of the tipping roller first, forming an angle. Because the upper board occupies the bottom space, the lower board cannot fit against the bottom of the tipping roller axis. After rotating 180º, it directly presses on the board located at the bottom of the tipping roller. Because the board remains at a high temperature during the cooling process on the flipping rollers, any deformation can solidify during cooling, retaining the deformation. This means that the board that falls to the bottom of the flipping rollers first cannot recover from its deformation. Firstly, this results in uneven surface texture during sanding, leading to uneven sanding depth and rough, inadequate edge sanding. This explains why an unevenly sanded edge appears every one or two boards during the sanding process. Secondly, it increases board deformation, affecting the appearance quality, increasing the difficulty of subsequent processing by customers, and causing customer complaints. Current production methods cannot meet the requirement of both improving production efficiency and reducing board deformation. Utility Model Content

[0027] like Figures 1-4 As shown in the figure, this embodiment provides a device for preventing deformation of artificial boards during the cooling process of the flipping wheel, comprising: The plate 13 detection module is used to detect whether there is a plate 13 on the grid frame 12 of the flip wheel; The compressed air hose has one end connected to a compressed air source and the other end connected to the telescopic cylinder 4. Solenoid valve 3 is installed on the compressed air pipe to block or open the compressed air pipe. Telescopic cylinder 4 is installed on the adjustment mechanism; Push plate 5 is fixedly connected to the piston rod of telescopic cylinder 4; An adjustment mechanism is located on the outside of the flap wheel and is used to adjust the distance between the telescopic cylinder 4 and the flap wheel.

[0028] The adjustment mechanism includes a movable base 7 and a slide rail 10. The telescopic cylinder 4 is mounted on the movable base 7. The movable base 7 is slidably connected to the slide rail 10. The movable base 7 is locked on the slide rail 10 by a locking assembly. The slide rail 10 is located on the outside of the flip wheel.

[0029] The movable base 7 includes a mounting plate and a connecting plate 17. The mounting plate is fixed on the connecting plate 17. The telescopic cylinder 4 is mounted on the mounting plate. The connecting plate 17 is slidably connected to the slide rail 10. The connecting plate 17 is locked on the slide rail 10 by a locking component.

[0030] The mounting plate includes a horizontal plate 16 and a vertical plate 15. The horizontal plate 16 is mounted on the connecting plate 17, and the vertical plate 15 is mounted vertically on the horizontal plate 16. The end of the telescopic cylinder 4 is in contact with and fixed to the vertical plate 15, and one side of the telescopic cylinder 4 is in contact with and fixed to the horizontal plate 16.

[0031] A limiting plate 14 is also provided on the horizontal plate 16, and the limiting plate 14 is in contact with the other end of the telescopic cylinder 4.

[0032] The connecting plate 17 has four connecting holes 9. The locking assembly includes four screws. There are two slide rails 10, which are spaced apart and parallel to each other. Each slide rail 10 has multiple spaced-apart locking blocks 11. Each locking block 11 has a threaded hole. The threaded holes of the four locking blocks 11 on the two slide rails 10 correspond to the four connecting holes 9. The four screws pass through the four connecting holes 9 and are threadedly connected to the four threaded holes.

[0033] The connecting plate 17 has four connecting holes 9. The locking assembly includes four screws and four nuts. There are two slide rails 10, which are spaced apart and parallel to each other. Each slide rail 10 has multiple spaced-apart locking blocks 11. Two adjacent locking blocks on each slide rail 10 form a limiting slot 18. The four limiting slots on the two slide rails 10 correspond to the four connecting holes 9. The four screws pass through the four connecting holes and the four limiting slots 18 respectively, and are locked by the four nuts respectively.

[0034] The push plate 5 has a rubber block 6 on the plane that contacts the plate 13.

[0035] The plate 13 detection module includes a photoelectric switch 1 and an intermediate relay 2. The photoelectric switch 1 is installed on the edge of the flip wheel and is used to detect whether there is a plate 13 on the grid frame 12 of the flip wheel. The intermediate relay 2 is connected to the photoelectric switch 1 and to the solenoid valve 3.

[0036] The slide rail 10 forms an angle α with the horizontal plane, where 0° < angle α ≤ 45°. Specifically, increasing the angle reduces the cylinder's thrust resistance. When angle α is less than 0°, no plate has yet entered the grid frame. Or, when angle α is greater than 45°, the plate above the grid tends to slide towards the bottom of the flip wheel's axis, rendering further pushing ineffective. Therefore, the aforementioned angle range is optimal.

[0037] The slide rail 10 is parallel to the grid frame of the flip wheel.

[0038] It should be noted that the dimensions of the slide rail 10 and the type of the telescopic cylinder 4 in the above embodiments can be changed according to the actual situation of the production line and actual needs.

[0039] In some embodiments, considering that the plate 13 has a large area, multiple telescopic cylinders 4 and push plates 5 may be needed to push it. Therefore, multiple anti-deformation devices as described in the above embodiments can be set up to push it together. The number of telescopic cylinders 4 can be flexibly increased or decreased according to the cylinder type, air pressure, and weight of the plate 13. As for how multiple cylinders move synchronously, it is only necessary to set the PLC controller to send signals to the solenoid valve 3 at the same time and open the compressed air pipe at the same time. This is the prior art and will not be elaborated on here.

[0040] In the above embodiment, the photoelectric switch 1 detects the presence of a material on the flip-up wheel grid frame. When a material is detected, it sends a signal to the intermediate relay 2. The intermediate relay 2 amplifies the signal and transmits it to the solenoid valve 3. In addition to amplifying the signal, the intermediate relay 2 also reduces electromagnetic interference in the factory environment, thereby increasing stability.

[0041] Solenoid valve 3 is connected to the compressed air pipe, providing real-time control over the opening and closing of the compressed air supply. Upon receiving a signal from photoelectric switch 1, solenoid valve 3 opens, allowing compressed air to be delivered to telescopic cylinder 4 via the pipe. Telescopic cylinder 4 is connected to push plate 5, which is made of stainless steel. Once the compressed air supply is connected, telescopic cylinder 4 pushes push plate 5 and the rubber block 6 fixed thereon to extend and retract, pushing the plate to the bottom of the tilting wheel axle. Rubber block 6 is made of polyurethane rubber, possessing high strength, flexibility, and elasticity to prevent damage to the plate during movement. Telescopic cylinder 4 is fixed to movable base 7, which is made of stainless steel and serves to support and move the cylinder, preventing displacement of the piston during movement. Four connecting holes 9 are located below the connecting plate. Screws passing through these holes 9 connect the plate to slide rail 10. The diameter of connecting holes 9 is 10mm. The four screws allow the connecting plate to move and be fixed on the slide rail by tightening or loosening the nuts. The flat plate 8, on which the slide rails are mounted, is parallel to the grid frame of the flip-up wheel and is made of stainless steel. Two rows of slide rails 10 support and fix the telescopic cylinder 4 and the movable base 7. The slide rails 10 allow the movable base 7 to move freely, facilitating flexible adjustment according to the width of the rough board. The slide rails 10 have locking blocks 11 distributed at certain intervals. When the telescopic cylinder 4 is in the correct position, the locking blocks 11 on the slide rails 10 can be tightened into the limiting slots 18 formed by the corresponding two locking blocks using screws with nuts. Then, tightening the nuts secures the movable base 7.

[0042] The main operating procedure is as follows: Before changing the size of the board, loosen the nuts on the four screws fixing the movable base 7, move the connecting plate 17, push the screws with nuts into the slide rail 10, adjust the position of the movable base 7 on the slide rail according to the width of the board, and after determining the appropriate position, insert the screws with nuts into the limiting slots 18 formed by the two corresponding locking blocks, and tighten the nuts to complete the corresponding operation. In actual production, it can be flexibly adjusted as needed, and the operation is simple and quick, meeting the needs of stacking multiple boards on the same grid at the same time, improving production efficiency, and preventing deformation during the cooling process of the flipped board and the problem of rough edges after sanding.
