Description

TECHNICAL FIELD

[0001] The utility model relates to timber processing technical field, concretely is a kind of adsorption structure of woodcarving machine. BACKGROUND

[0002] Woodcarving machine is mainly used for wood processing, so that it is more beautiful value. Woodcarving machine is various, and it is understood that, to the woodwork machinery product for furniture production in current domestic, it is tending to high-grade. According to incomplete statistics, at present, China's annual output of timber is fifty million cubic meters, and artificial board is about five million cubic meters. The demand for woodwork machinery is up to sixty billion yuan per year.

[0003] The original wood carving machine is usually fixed by using a clamp when carving wood. The ordinary clamp usually applies pressure to the wood through several fixed points or surfaces to achieve fixation, which is difficult to ensure that the entire surface of the wood is uniformly stressed. During the carving process, the wood may deform due to uneven local stress, affecting the carving accuracy. When using a C-shaped clamp or other clamps to fix the wood board, the parts contacted by the clamp are fixed firmly, but the area between the clamps may have slight shaking or displacement.

[0004] And the ordinary clamp may leave pressure marks on the surface of the wood, or even damage the surface of the wood due to excessive pressure, especially for wood with soft texture or special surface requirements. Such damage may affect product quality. Therefore, we propose a kind of adsorption structure of woodcarving machine to solve the above problems. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at solving one of the technical problems existing in the prior art or related art.

[0006] Therefore, the utility model adopts the following technical scheme:

[0008] Preferably, the top of the assembly cylinder is fixedly connected with a suction cup, and the output end of the servo motor is fixedly connected with the driving roller.

[0009] Preferably, a fixed ring groove is arranged around the negative pressure plate, and a sealing ring is sleeved in the fixed ring groove.

[0010] Preferably, a rotating bearing is sleeved on the top of the driving roller, and the driving roller is rotatably connected with the negative pressure plate through the rotating bearing.

[0012] Preferably, the sliding seat is slidably connected with the inner wall of the assembly window, and the sliding seat is provided with an extension spring on the side close to the assembly cylinder.

[0013] Preferably, a gasket is arranged on the end face of each of the plurality of clamping plates close to each other.

[0014] Preferably, an inclined surface matched with the end face of the top base close to the trigger base is arranged on the end face of the top base close to the trigger base, and the top base is slidably connected with the trigger base.

[0015] By adopting the above technical scheme, the wood carving machine has the following beneficial effects:

[0016] The suction structure of the wood carving machine mainly comprises an assembly cylinder, and the assembly cylinder is internally provided with a suction assembly. The communication window at the top of the assembly cylinder is connected with a suction cup, and the negative pressure plate is arranged in the assembly cylinder. The sealing ring around the negative pressure plate guarantees good air tightness. The bottom servo motor drives the driving roller with external threads. After the motor is turned on, the driving roller moves downward along the threads, and the negative pressure plate also moves downward, so that the space in the assembly cylinder is increased, the air pressure is reduced, and negative pressure is formed. The suction force is transmitted to the suction cup through the communication window, so that the wood is adsorbed.

[0017] The motion plate of the fixing assembly is sleeved on the driving roller and moves downward synchronously with the driving roller. The pull rod at the top of the motion plate is connected with the top base. The inclined surface of the top base and the trigger base are matched with each other. When the pull rod moves downward with the motion plate, the top base extrudes the trigger base, the sliding seat slides in the assembly window and compresses the extension spring, and then drives the clamping plates to move close to each other, so as to tightly fix the wood.

[0018] Compared with the traditional mode, the synchronous mode of adsorption and fixation does not need to be operated in sequence, and a lot of preparation time before processing is saved. During the processing, the wood can be subjected to stable force in multiple directions, effectively resisting the vibration and external force generated during carving, and guaranteeing the smooth processing. At the same time, due to the double support of adsorption and fixation, the clamping force required by the clamping plate is reduced, and the appearance of the wood can be effectively protected, so as to protect the integrity and appearance of the wood, and provide powerful protection for the processing of the wood carving machine.
