[0002] The veneer and veneer decoration industry started in the 1950s. After half a century of development, it has reached a considerable scale. Especially in the past two decades, with the leapfrog growth of my country's furniture manufacturing industry and decoration and renovation industry, its development has been rapid.

[0003] With the development of industry, the pressing and pasting of veneer has gradually changed from traditional manual pressing to automatic equipment pressing. For example, an efficient and intelligent wooden board rapid veneer device (patent number: CN202020112194.5) includes a wooden board veneer machine, a dust removal box is fixedly installed on one side of the wooden board veneer machine, a negative pressure motor is fixedly installed inside the dust removal box, the output end of the negative pressure motor is fixedly connected to the input end of the dust hood, the bottom end of the dust hood is fixedly provided with a bottom groove, a base is fixedly installed below the bottom groove, a conveying motor is fixedly installed inside the base, a conveyor belt is sleeved on the outside of the conveying motor, the output end of the negative pressure motor is fixedly connected to the input end of the conduit, one end of the conduit is plugged into one end of the dust filter chamber, and an attachment box is fixedly installed at one end of the wooden board veneer machine. The utility model removes the adsorbed dust on the surface of the wooden board through the installed negative pressure motor, prevents the dust from affecting the effect of veneer, and thus improves the use effect.

[0004] The existing veneer pressing device has poor compatibility when pressing veneer on the surface of board materials, and it is difficult to press boards of different thicknesses. In addition, since the diameter of the veneer cylinder will decrease after continuous pressing, the existing pressing device cannot reflect the pressing pressure according to the decrease in the cylinder diameter, and manual judgment and adjustment are required, which affects the quality and efficiency of the veneer pressing process. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing veneer pressing device has poor compatibility when pressing veneer on the surface of a board, and is difficult to satisfy the requirements of pressing boards of different thicknesses. Moreover, since the diameter of the veneer cylinder will decrease after continuous pressing and use, the existing pressing device cannot reflect the pressing pressure according to the decrease in the cylinder diameter, and manual judgment and adjustment are required, which further affects the quality and efficiency of the veneer pressing process.

[0006] The utility model adopts the following technical solutions to solve the above technical problems: a veneer pressing device for leather paint panels, comprising a rectangular base, legs, and a control panel for control, wherein the top surface of the base is concave and a plurality of rollers are arranged along the length direction of the base at the concave part, wherein a plurality of motors A for driving the rollers are arranged in the base, and the rollers are connected to the motors A through bearings; a pad is arranged in the concave part in the middle of the base, a pressure sensor assembly is arranged at the bottom of the pad, and a boss is arranged on both sides of the middle of the base, A frame shell with three sides of panels is provided on the top of the two bosses, an inverted motor B is provided in the frame shell above the two bosses, a hydraulic cylinder is provided in the two bosses, the hydraulic cylinder is connected to the motor B through a vertical hydraulic rod, the two motors B are driven by a rotating shaft, a veneer roller is provided between the two motors B and directly above the pad, and both ends of the veneer roller are connected to the rotating shaft through a connecting shaft; the motor A, the motor B, the hydraulic cylinder, and the pressure sensor assembly are all connected to the control panel through a circuit.

[0007] Preferably, the end surface of the rotating shaft is concave to form a cylindrical groove, the inner diameter of the groove is the same as the outer diameter of the connecting shaft, and a detachable end cover is provided at the rotating shaft at the groove. The groove formed by the concave of the rotating shaft and the detachable end cover allow the connecting shaft to be removed and reassembled from the rotating shaft, thereby realizing the function of replacing the veneer roller.

[0008] Preferably, the end cap and the connecting shaft are provided with threaded holes with the same inner diameter, and the two threaded holes are screwed together by a screw. The end cap and the connecting shaft are provided with threaded holes and connected by a screw, and the threaded fastening structure is used for operation to support the action of replacing the veneer roller.

[0009] Preferably, the tops of the plurality of rollers are flush with the top surface of the pad, so that the wooden board can move horizontally during the veneer pressing process, thereby ensuring the stability of the pressing process.

[0010] Preferably, a pressing plate is provided on one side of the backing plate on the machine base, and an adjusting assembly is provided on both ends of the pressing plate on the machine base, and both ends of the pressing plate are connected to the adjusting assembly through protruding convex shafts.

[0011] Preferably, the adjustment assembly is composed of a threaded sleeve, a threaded shaft, a connecting bearing, and a connecting ball. The bottom end of the threaded shaft is fixed on the machine base, the threaded sleeve is sleeved on the threaded shaft, the connecting ball is located above the threaded sleeve and is rotatably connected through the connecting bearing, and the convex shaft is connected to the connecting ball. The arrangement of the threaded sleeve, the threaded shaft, and the connecting bearing allows the height position of the pressure plate to be adjusted by directly manually rotating the threaded sleeve, thereby matching the conditions according to the plate materials of different thicknesses.

[0012] Preferably, the pressing plate is tilted as a whole and tilts from top to bottom along the discharging direction. The pressing plate tilts from top to bottom along the discharging direction, which can reduce the mutual impact force when it is in contact with the wooden board, avoiding setbacks and damage to the wooden board.

[0013] Preferably, the control panel is connected to the frame shell via two connecting rods, and a steering ball is provided between the two connecting rods and between one connecting rod and the control panel. The setting of the steering ball enables the control panel to move its position to adjust to a better control point for operation.

[0014] Preferably, there are six legs, four of which are arranged at the four corners of the bottom of the base, and the other two are arranged at the bottom of the two bosses. A leg is arranged at the bottom of each of the two bosses to increase the supporting force and ensure the stability of the entire boss structure when the motor B is driven.

[0015] Preferably, the top ends of the two frame shells are concave and a removable cover is provided at the concave portion. The provision of the cover can prevent dust from falling onto the veneer roller.

[0016] The utility model adopts the above technical solution, and compared with the prior art, has the following technical effects:

[0017] (1) By setting up a hydraulic cylinder and a hydraulic rod, the height of the motor B and the veneer roller can be adjusted to be suitable for pressing boards of different thicknesses.

[0018] (2) By arranging a pressure sensor assembly at the bottom of the pad, the pressure of the veneer roller on the wooden board can be automatically sensed and displayed, which helps the operator to adjust the veneer roller according to the change of the roller diameter.
