A sawdust recovery, separation and packaging device for wood processing

Abstract

The invention discloses a sawdust recovery, separation and packing device for wood processing. A feeding pipe is arranged on the upper end of the left side surface of the box body, a negative pressure fan is arranged on the upper end of the right side surface of the box body, a motor 1 is arranged on the upper end of the box body, and a guide in the box body A feeding screw 1 is arranged between the block and the upper end surface of the box body, and the left and right sides of the lower end surface of the guide block are respectively connected with a rotating shaft 1 and a rotating shaft 2, and the lower ends of the rotating shaft 1 and the rotating shaft 2 are respectively provided with a connecting block 1 and a connecting block 2, and the connecting block Blade 1 and blade 2 are evenly arranged on the sides of the first and connecting block two, the left and right ends of the movable frame are exposed to the box, the movable frame is equipped with a screen, the transmission rod is equipped with a cam, and the lower end of the left side of the box is equipped with a motor four. , the lower end in the box and the feed pipe are rotatably connected with feed screw two, and the feed pipe is communicated with the packaging and forming device. The invention has the advantages of good recovery effect of sawdust, can process the flue gas generated when sawdust is cut, can crush, sieve and pack the sawdust, and has a compact structure.

Description

technical field [0001] The invention relates to the technical field of wood processing equipment, in particular to a sawdust recovery, separation and packing device for wood processing. Background technique [0002] The most basic definition of wood is that after the trees are felled, they can be processed to be used for construction or manufacturing. Because of its easy acquisition and processing, it has been the main building material used by humans since ancient times. The wood processing industry is an industry that uses wood as raw material and uses mechanical or chemical methods to process it to achieve the corresponding purpose. [0003] In the process of wood cutting and processing, a large amount of sawdust will be produced, which will interfere with the operation of the operator and adversely affect the health of the operator. At the same time, wood chips have good economic value, so it is necessary to recycle wood chips generated during wood processing. The exis...

AI Technical Summary

Problems solved by technology

[0004] 1. The recovery cover is mostly installed on the side of the cutting disc, which does not completely match the direction of the sawdust splashing, resulting in incomplete collection of sawdust;

[0005] 2. There is no feeding device in the box for the preliminary treatment of wood chips, so that the wood chips entering the box under the action of the negative pressure fan cannot be quickly dropped, and the wood chips are easy to accumulate at the feeding port, which affects the collection effect of the negative pressure fan on the wood chips;

[0006] 3. There is a lack of a crushing device for wood chips. Due to the large size difference of the saw chips generated during cutting, if the saw chips are simply screened by the screening device, there are many saw chips that do not meet the particle size requirements, and special equipment is still needed to treat the particles that do not meet the particle size requirements. The required wood chips are processed twice, which increases equipment investment and restricts the improvement of production efficiency;

[0007] 4. Wood chips that do not meet the particle size requirements on the screening device need to be discharged manually, which increases labor costs and hinders the improvement of production efficiency;

[0009] 6. The packing and forming device usually drives the push plate to move a certain distance to press and form the sawdust through the hydraulic cylinder, and it is impossible to control the extension distance of the hydraulic cylinder piston rod according to the actual pressing of the sawdust;

[0010] 7. There is no treatment device for the smoke generated during wood cutting, and the smoke is directly discharged, which endangers the safety of operators
