Description

A new type of edge strip recycling and crushing device

technical field

The utility model relates to the field of waste board recycling, in particular to a novel side strip recycling and crushing device.

Background technique

Medium density fiberboard is a kind of artificial board made of wood or plant fiber by mechanical separation and chemical treatment, mixed with adhesives and waterproofing agents, etc., and then formed by high temperature and high pressure. It is an ideal artificial board for making furniture; medium density The structure of fiberboard is more uniform than that of natural wood, and it also avoids problems such as decay and moth-eaten. At the same time, it has small expansion and shrinkage, which is easy to process; because the surface of MDF is flat, it is easy to paste various finishes, which can make the finished furniture more beautiful. ; In terms of bending strength and impact strength, it is superior to particleboard. In the production process of medium density fiberboard, in order to reduce costs and save raw materials, edge strips and waste boards should be recycled and reused.

When the edge strips and waste boards are recycled and reused, due to the high density and high surface bonding strength of the high-quality boards produced in the factory, the edge strip machine cannot smash the recycled edge strips and waste boards. After multiple or repeated crushing, the recycled edge strips and waste boards do not meet the standard of reuse. When recycling and crushing edge strips and waste boards, the speed of transmission cannot be adjusted, and at the same time, the edge strips and waste boards cannot be preliminarily cut, which will easily block the transmission parts of edge strips and waste boards. In this case, when producing P2 boards, the There is a high probability of flaky edge particles on the surface, which are visible to the naked eye and are very obvious, which can easily lead to quality degradation.

Therefore, how to design a new type of edge strip recycling and crushing device has become a problem that we need to solve at present.

The bottom end of the waste shredding mechanism 2 is provided with a bottom plate 10 .

Preferably, a plurality of V-shaped pulverizing blades 16 are arranged on the periphery of the pulverizing roller 15 , the V-shaped pulverizing blades 16 are provided with blades in both directions, and a protrusion is also arranged between the two V-shaped pulverizing blades 16 on the pulverizing roller 15 It reduces the dead angle or blind area of the V-shaped pulverizing blade 16 on the pulverizing roller 15, so that after the pulverizing roller 15 rotates, the materials falling on the pulverizing roller 15 can be cut and pulverized, so that the edge or waste All of them can be recycled and crushed, which effectively improves the cutting and crushing effect of waste recycling and crushing.

Preferably, the arc filter plate 5 is provided with a clip slot 17, the clip slot 17 is arc-shaped, and the clip slot 17 is embedded with an arc-shaped waste screen 18, and the arc-shaped waste screen 18 and the clip slot 17 are both arc-shaped, The waste shredding mechanism 2 can shred the conveyed waste or edge, and can repeatedly shred the waste or edge that does not meet the standard. In the waste crushing mechanism 2, the crushing drive motor 4 drives the crushing drive roller 7 to rotate through the transmission belt 8, so that the crushing drive roller 7 drives the crushing roller 15 to rotate, and the crushing roller 15 drives the V-shaped crushing blade 16 to rotate. After entering the waste crushing mechanism 2, it will be cut and crushed by the rotating V-shaped crushing blade 16. After being cut and crushed by the V-shaped crushing blade 16, the waste or edge strips that meet the crushing standard will pass through the arc filter plate 5. The installed arc-shaped waste screen 18 is then discharged from the discharge pipe 6 that communicates with the waste crushing mechanism 2. After being cut and crushed by the V-shaped crushing blade 16, the waste or edge that does not meet the crushing standard will be curved. The waste screen 18 is blocked, so that the waste or edge strips that do not meet the crushing standard remain in the waste crushing mechanism 2 and continue to be cut and crushed by the rotating V-shaped crushing blade 16 until the crushing standard is reached. The discharge pipe 6 is discharged. When replacing the arc-shaped waste screen 18 with different apertures, only the arc-shaped filter plate 5 needs to be pulled out from the side of the waste crushing mechanism 2, and the arc-shaped waste screen 18 can be directly removed from the waste shredding mechanism 2. The card slot 17 on the arc filter plate 5 is taken out and replaced, which eliminates the large particles in the edge of the scrap after recycling and crushing, avoids the occurrence of large flake particles in the scrap or edge after re-shredding, and prevents the production of P2 boards. At this time, there is a high probability of flaky edge particles on the board surface, which effectively improves the quality of P2 board production.

Preliminary cutting and conveying, and can also adjust the speed of waste or edge blanking and conveying, after adding the waste or edge strip into the top hopper 12, adjust the scrap by moving the length of the movable baffle 13 embedded in the top hopper 12 Or the speed at which the edge strips fall into the waste feeding drum 1, so as to adjust the feeding speed, and after the scrap or edge strips fall into the waste feeding drum 1, the screw feeding roller 14 driven by the feeding drive motor 11 is clockwise. Rotate, and let the spiral cutting edge 19 cut the scrap or edge strips falling into the waste feeding drum 1 while rotating, and at the same time transfer the scrap cut by the spiral cutting edge 19 to the waste conveying drum through the spiral feeding roller 14 3 places, and then the cut waste or edge strips are transferred to the waste crushing mechanism 2 through the waste transfer drum 3, so that the waste or edge strips can complete the preliminary cutting work during transmission, and can also adjust the bottom of the top hopper 12. Therefore, the screw feeding roller 14 can not transport the waste material or edge strips dropped from the top hopper 12 in time, preventing the internal blockage of the waste feeding cylinder 1, and effectively improving the practicability of the device.

Working principle: During implementation, first add waste or edge strips into the top hopper 12, and then pull or move the movable baffle 13, so that the waste or edge strips in the top hopper 12 fall into the waste feeding cylinder 1, and let the screw The spiral cutting edge 19 on the feeding roller 14 will cut the waste material or edge strips dropped into the waste feeding drum 1, and then transfer the preliminarily cut waste material or edge strips to the waste conveying drum 3 through the screw feeding roller 14, The scrap or edge strip after preliminary cutting is transported into the scrap crushing mechanism 2, and the crushing drive motor 4 drives the crushing roller 15 to rotate through the transmission belt 8 and the crushing drive roller 7, so that the crushing roller 15 drives the V-shaped crushing blade 16 to rotate, so that the The V-shaped shredding blade 16 rotating inside the scrap shredding mechanism 2 shreds the scraps or edgings transferred into the scrap shredding mechanism 2, and filters and shreds the unqualified scraps or edgings through the arc-shaped waste screen 18.
