Description

Technical Field

[0001] The utility model relates to the field of artificial board pre-pressing, in particular to an artificial board pre-pressing machine capable of preventing deviation and clamping. Background Art

[0002] The pre-pressing machine is an auxiliary machine of the particleboard production line. It is a mechanical equipment for preliminary bonding before gluing in order to shorten the hot pressing cycle and improve the quality of the board during the production process. When the pre-pressing machine is performing the pre-pressing operation, since the artificial boards are filled with air and shavings, the artificial boards are affected by the internal shavings and air when they are pressed, which will cause the artificial boards to deflect, thereby affecting the subsequent process. Therefore, in order to solve the problem that artificial boards are prone to deflection during the pre-pressing process, a pre-pressing machine for artificial boards with anti-deflection clamping is proposed. Utility Model Content

The gap between the upper and lower support frames is set, and the pre-pressing thickness is set to pre-press the artificial boards in between. The surface of the artificial board slabs pre-pressed by the pre-pressing machine is smooth, and the air inside the slabs can be exhausted, which helps to increase the production speed of the entire production line; reduce the back-spray when the slabs enter the press and cause cracks on the board surface, affecting the quality of the finished slabs; since the thickness cylinder of the pre-pressing machine can adjust the gap between the upper and lower support frames, the pre-pressing pressure can be adjusted to avoid excessive pressure causing the artificial board to be offset, and to avoid insufficient pressure causing the pressing force to be insufficient.

[0005] Preferably, an infrared sensor is provided on the left side of the upper support frame, and a driving pulley body is provided on the right side of the lower support frame and the inner part of the upper support frame. A number of lower pressure rollers are provided at equal intervals on both sides of the lower support frame corresponding to the driving pulley body, and a number of upper pressure rollers are provided at equal intervals on both sides of the upper support frame corresponding to the driving pulley body. The model of the infrared sensor is CTL-SF75-C3. When an artificial board enters the middle of the upper support frame and the lower support frame, the infrared sensor detects the object and transmits the detected data to an external PLC controller. The PLC controller controls the start-up of the shavings recovery device body, the belt blowing device body and the driving pulley body.

[0006] Preferably, a mesh belt tensioning device body is provided on the top left side of the upper support frame, and a mesh belt part is installed on the outer side of the upper support frame, the mesh belt tensioning device body and the upper pressure roller.

When the artificial board moves toward the discharge port, the air and shavings debris inside it will be squeezed out, and the shavings debris will stick to the mesh belt part and the artificial board. The belt blowing device body cleans the shavings debris on the mesh belt part, so that it detaches from the mesh belt part and falls into the interior of the shavings recovery device body for recovery.

[0008] Preferably, a limiting pulley is provided at the middle bottom of the rear side surface of the upper support frame, and a pulley guide rail is provided at the middle top of the rear side surface of the lower support frame. The limiting pulley is stuck in the inside of the pulley guide rail, and two limiting telescopic rods are symmetrically provided on the left and right sides of the rear side of the lower support frame.

The output end of the thickness-fixing oil cylinder drives the upper support frame to move up and down in the vertical direction by driving the telescopic rod to adjust the gap between the upper support frame and the lower support frame. When the artificial board passes through, the thickness-fixing oil cylinder is started to drive the upper support frame to move downward, adjust the gap between it and the lower support frame, and set the pre-pressing thickness, so as to pre-press the artificial board in between. The surface of the artificial board slab pre-pressed by the pre-pressing machine is flat, and the air inside the slab can be exhausted, which helps to increase the production speed of the entire production line; reduce the back spray when the slab enters the press and cause cracks on the board surface, affecting the quality of the finished slab; since the thickness-fixing oil cylinder of the pre-pressing machine can adjust the gap between the upper support frame and the lower support frame, the pre-pressing pressure can be adjusted to avoid excessive pressure causing force deviation of the artificial board, and to avoid insufficient pressure causing insufficient pressure on the pressing plate.

The top of the limited telescopic rod 10 is connected to the rear side of the upper support frame 3. The artificial board is fed from the feed port of this pre-pressing machine, and the thickness cylinder 11 is started to provide an upward and downward telescopic driving force. The output end of the cylinder 11 drives the upper support frame 3 to move up and down in the vertical direction by driving the telescopic rod 12 to adjust the gap between the upper support frame 3 and the lower support frame 13. When the artificial board passes through, the thickness-setting oil cylinder 11 starts to work and drives the upper support frame 3 to move downward, adjusts the gap between it and the lower support frame 13, and sets the pre-pressing thickness, thereby pre-pressing the artificial board in between. The surface of the artificial board slab pre-pressed by the pre-pressing machine is flat, and the air inside the slab can be emptied, which helps to improve the production speed of the entire production line.To reduce the cracks on the board surface caused by the back spray when the slab enters the press, which affects the quality of the finished slab, when the upper support frame 3 moves up and down, the limiting pulley 8 slides up and down in the pulley guide rail 9, and the limiting telescopic rod 10 follows the upper support frame 3 to perform telescopic operations, and the upper and lower moving positions of the upper support frame 3 are limited by the pulley guide rail 9 and the limiting telescopic rod 10 to maintain the stability of the upper support frame 3 when moving.

The artificial board is driven to move toward the discharge port through the mesh belt 4 and the driving pulley body 16 on the lower support frame 13. When the artificial board moves toward the discharge port, the lower pressure roller 15 is driven to rotate passively. At the same time, the air and wood shavings inside the artificial board will be squeezed out of the outside, and the wood shavings will stick to the mesh belt 4 and the artificial board.
