Description

Technical Field

[0001] This utility model belongs to the field of wood processing technology, specifically relating to a wood surface pretreatment device. Background Technology

[0002] Wood processing technology includes basic processing techniques such as wood cutting, wood drying, wood gluing, and wood surface decoration, as well as functional treatment techniques such as wood protection and wood modification.

[0003] When processing the surface of wood, it is necessary to remove burrs by sanding to make the surface of the wood smooth. The sanding effect directly affects the subsequent processing and quality of the wood.

[0004] Existing methods for removing burrs require wiping the surface of the wood with a damp cloth before sanding to moisten it. The moisture absorption and expansion properties of the wood cell walls cause the collapsed burrs on the wood to stand up. By pre-treating the surface of the wood, the effect of sanding to remove burrs can be guaranteed. However, the current wiping is mainly done manually, which not only has limited uniformity of moistening, but also makes it easy for the operator's hands to be pricked by burrs. Utility Model Content

[0025] Please see Figures 1-6 The present invention provides the following technical solution: including a conveyor belt 1, a support frame 2 above the conveyor belt 1, a water storage box 3 fixedly connected to the support frame 2, a rubber layer 31 at the bottom of the water storage box 3, a fixing block 32 at the bottom of the rubber layer 31, an absorbent cloth 4 on one side of the fixing block 32, and the part of the absorbent cloth 4 away from the fixing block 32 located inside the water storage box 3, so that the surface of the wood is moistened by the contact between the absorbent cloth 4 and the wood.

[0026] This embodiment includes a conveyor belt 1, which is existing technology and is not an improvement of this utility model, so it will not be described in detail in the specification. When the wood is on the conveyor belt 1, it can be moved horizontally by the conveyor belt 1. A support frame 2 is provided above the conveyor belt 1, and the support frame 2 is fixedly connected to the conveyor belt 1. When the conveyor belt 1 transmits the wood, the wood will pass under the support frame 2. A water storage box 3 is fixedly connected to the support frame 2. A rubber layer 31 is provided at the bottom of the water storage box 3, and a fixing block 32 is provided at the bottom of the rubber layer 31. When the wood passes under the fixing block 32, the wood will push the fixing block 32 upward, and the rubber layer 31 will be compressed by the fixing block 32. The rubber layer 31 is made of a high-resilience material. After the wood passes, the rebound of the rubber layer 31 will drive the fixing block 32 to move downward and reset. When the wood is under the fixing block 32, the rebound force of the rubber layer 31 will apply downward pressure to the fixing block 32. An absorbent cloth 4 is provided on one side of the fixing block 32. The friction between the conveyor belt 1 and the wood is greater than the friction between the wood and the absorbent cloth 4. The absorbent cloth 4 is fixedly connected to the fixing block 32. When the wood passes between the fixing block 32 and the conveyor belt 1, the wood will come into contact with the absorbent cloth 4. When the absorbent cloth 4 is wet, the contact between the absorbent cloth 4 and the wood can achieve the purpose of wetting the surface of the wood. The part of the absorbent cloth 4 away from the fixing block 32 is located inside the water storage box 3. When the water storage box 3 contains water, the part of the absorbent cloth 4 inside the water storage box 3 will be immersed in water. The absorbent cloth 4 will absorb the water inside the water storage box 3. Through the transfer of water, the part of the absorbent cloth 4 connected to the fixing block 32 will remain wet. After the wood absorbs the water on the absorbent cloth 4, the absorbent cloth 4 will continue to absorb the water inside the water storage box 3, so that the absorbent cloth 4 can continuously wet the wood, ensuring the efficiency and uniformity of the wet pretreatment, which is conducive to the subsequent thorough sanding of burrs and ensuring the quality of the wood surface treatment.

[0027] The water storage box 3 has a partition 33 inside, which separates the water storage chamber 34. The absorbent cloth 4 is folded back on the top of the partition 33 and located on both sides of the partition 33. The partition 33 is fixedly connected to the water storage box 3, and there is a distance between the two sides of the water storage box 3 and the inner walls of the two sides of the water storage box 3. When water is poured into the water storage chamber 34, the part of the absorbent cloth 4 located inside the water storage chamber 34 will be immersed in water, thereby achieving the purpose of absorbing water with the absorbent cloth 4. This allows the part of the absorbent cloth 4 in contact with the wood to be continuously replenished with water, ensuring the uniformity of the wood's moisture.

[0028] One side of the fixing block 32 is curved, and the absorbent cloth 4 covers the curved surface of the fixing block 32. The curved surface of the fixing block 32 keeps the shape of the absorbent cloth 4. The curvature of the absorbent cloth 4 and the fixing block 32 makes it easy to push the wood to the bottom of the fixing block 32 and the absorbent cloth 4.

[0029] The support frame 2 has an empty slot, and the water storage box 3 is fixedly connected to the inside of the empty slot; the water storage box 3 is in a vertical state, while the fixing block 32 is in a horizontal state, and the length of the fixing block 32 is greater than the length of the water storage box 3.

[0030] Both sides of the water storage box 3 are provided with damping layers 35. A connecting block 36 is provided on the side of the damping layer 35 away from the water storage box 3. Two connecting rods 321 are provided on the top of the fixing block 32. A through groove 361 is opened on the connecting block 36. The connecting rod 321 is slidably connected to the inside of the through groove 361. The connecting rod 321 is fixedly connected to the fixing block 32 and is perpendicular to the fixing block 32. The dimensions of the through groove 361 and the connecting rod 321 are matched. When the fixing block 32 moves up and down, the connecting rod 321 will slide inside the through groove 361. The damping layer 35 allows the connecting block 36 to make lateral displacement, thereby avoiding the situation where the fixing block 32 is subjected to lateral thrust when the wood is pushed to the bottom of the fixing block 32, and the connecting rod 321 and the connecting block 36 get stuck.

[0031] The absorbent cloth 4 extends through the bottom of the water storage box 3, and the side of the absorbent cloth 4 away from the fixing block 32 is fixedly connected to the bottom of the water storage cavity 34. The partition 33 can keep the absorbent cloth 4 flat. Since the absorbent cloth 4 is fixedly connected to the water storage box 3, it can prevent the absorbent cloth 4 from shifting. When the water level in the water storage cavity 34 drops, part of the absorbent cloth 4 will also be immersed in water.

[0032] The top of the water storage box 3 is open; water can be replenished inside the water storage chamber 34 through the top of the water storage box 3, and the water level inside the water storage chamber 34 can also be easily observed.

[0033] The working principle and usage process of this utility model are as follows: First, water needs to be added to the water storage chamber 34. Then, the wood to be moistened is pushed to the bottom of the fixing block 32 and the absorbent cloth 4. The wood will then come into contact with the absorbent cloth 4, which moistens the surface of the wood. Since other parts of the absorbent cloth 4 are immersed in water, as the water in the part of the absorbent cloth 4 in contact with the wood is lost, the absorbent cloth 4 will absorb the water, thus keeping the part of the absorbent cloth 4 in contact with the wood always moist. As the wood moves, the absorbent cloth 4 can evenly moisten the surface of the wood. When the wood passes under the fixing block 32, the wood will push the fixing block 32 upwards, and the rubber layer 31 will be compressed by the fixing block 32 to make way for the wood. When the wood is below the fixing block 32, the rebound force of the rubber layer 31 will apply downward pressure to the fixing block 32, allowing the absorbent cloth 4 to fully contact the wood, so that the burrs on the wood can be fully erected, facilitating subsequent sanding and improving the efficiency of burr removal.
