Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of wooden pallets, in particular to a heat treatment device for wooden pallets. Background Art

[0002] The wooden pallet heat treatment device is a device used to heat treat wooden pallets. Its main function is to improve the physical properties, durability and insect and anti-corrosion ability of wooden pallets by heating and treating them. The following are the general components and working principles of wooden pallet heat treatment devices: Heating system: used to heat the pallet to a specific temperature range. Temperature control: to ensure that the pallet is treated within the appropriate temperature range. Treatment chamber: The treatment chamber usually has insulation and heat preservation materials to reduce heat loss. Air circulation: In order to evenly heat and treat the pallet, the device may contain an air circulation system, such as a fan or ventilation equipment, to ensure that the hot air circulates in the treatment chamber. Time control: The heat treatment device can set the treatment time, cooling system: After the treatment is completed, the device may be equipped with a cooling system to gradually reduce the temperature of the pallet to avoid damage to it due to sudden temperature changes. Heating the wooden pallet through the heat treatment device can kill pests, fungi and microorganisms in the wood, reduce the moisture content of the wood, and improve the durability and stability of the pallet. The pallets treated in this way are more reliable and durable during storage and transportation.

The limitation is too great, and the fixing device on the carrying plate needs to be started manually, which increases labor intensity and reduces work efficiency. It is also easy to cause the risk of burns. Therefore, a wooden pallet carrying rack that can adapt to different thicknesses is needed. Utility Model Content

[0023] Furthermore, the end points of the pair of L-shaped rods 22 at the bottom are located at a support plate 23, a rotation groove 24 is provided at the vertical plane where the support plate 23 and the L-shaped rod 22 intersect, a rotating cylinder 25 is provided between the vertical planes inside the rotating groove 24, a rocker 26 is provided through the rod body of the rotating cylinder 25, and an arc block 27 is provided through the end point of the rocker 26 away from the rotating cylinder 25.

[0024] Working principle: When the device is working, the U-shaped plate 19 is first adjusted according to the thickness of the tray to be heated next, and then the tray is transported to the lowest L-shaped placement plate 6 through the conveyor belt. During the transportation of the tray, it will first contact the fixed block 13. Because a slide groove is provided at the intersection of the fixed block 13 and the L-shaped placement plate 6, the tray will push the fixed block 13 to move. Because a memory spring 14 is provided through the vertical surface of the fixed block 13, a rectangular block 15 is also provided on the upper surface of the L-shaped placement plate 6. An L-shaped groove 16 is provided at the intersection of the rectangular block 15 and the L-shaped placement plate 6, and the L-shaped groove 16 is connected to the rectangular groove 8. The memory spring 14 is connected to the protrusion 17 at the end point of the rectangular block 15. , a protrusion 17 is also provided at the vertical surface of the rectangular block 15 facing the fixed block 13, a pair of protrusions 17 are symmetrical, and the protrusions 17 are also on the same horizontal plane, so when the fixed block 13 slides with the rectangular block 15, the L-shaped connecting rod 18 at the lower surface of the rectangular block 15 will also drag the moving tooth plate 12 to move, because the gear column 10 and the moving tooth plate 12 are in meshing relationship, and when the moving tooth plate 12 is dragged, the round rod 9 will drive the stopper 11 to rotate, and at this time, when the stopper 11 is rotating, the head will first contact the bottom surface of the rectangular groove 8, and when the gear column 10 is resisted by the stopper 11, the gear column 10 will not continue to rotate, and because the intersection of the guide block on the upper surface of the moving tooth plate 12 and the bottom plate is provided with The guide block 15 is connected to the guide block 15 by a memory spring, and the other end of the memory spring is connected to the vertical surface of the rectangular groove. The arc surface of the guide block is connected to the rectangular groove. Therefore, when the guide block on the movable tooth plate 12 contacts the gear column 10, it will be bent by the tension band, and when it comes out, it will be pushed straight by the memory spring. As the tray is continuously pushed in, the fixed block 13 will also move continuously. Because the length of the L-shaped groove 16 is not as long as the sliding groove at the lower end of the fixed block 13, the memory spring 14 will retract when the fixed block 13 continues to be pushed, thereby disengaging from the rectangular block 15. Because a reset spring is provided at the short vertical surface of the L-shaped groove 16 away from the stop block 11, and the other end of the reset spring One end is connected to the L-shaped connecting rod 18, so the movable tooth plate 12 will also rebound, causing the stopper 11 to rotate in the opposite direction, and finally causing the stopper 11 to change from an inclined device to a vertical device. At this time, the tray is also completely entered into the L-shaped placement plate 6, and then the motor 5 is started, so that the threaded rod 3 drives the lowest L-shaped placement plate 6 to descend, and then the rectangular telescopic sleeve rod 7 is pulled to make the film inside it slowly approach the arc block 27, and the arc block 27 will be rotated by the thrust, and when the film is completely entered between the L-shaped rods 22, the film will be sandwiched between the L-shaped rods 22, and then the telescopic rod body of the rectangular telescopic sleeve rod 7 will pull the upper L-shaped placement plate 6 to descend, and so on. After it is full, it can be pushed into the heating box for heating.
