[0001] This utility model relates to the field of wood veneer processing technology, specifically a wood veneer leveling machine. Background Technology

[0002] With the continuous development of my country's national economy, people's requirements for quality of life are constantly improving, and their demands are becoming more diversified. The demand for timber in various fields such as construction, interior decoration, and furniture manufacturing has increased significantly. Among them, using a rotary cutting machine to rotate and cut timber into circles can cut a relatively thick tree trunk into multiple timber boards, which are widely used in furniture, building materials, packaging materials and other fields. In addition, some waste is generated during the rotary cutting process. This waste can be sent to paper mills as raw materials for papermaking after secondary slicing.

[0003] Because the waste contains a large number of impurities, it is necessary to separate the impurities. However, manual separation is not only inefficient and labor-intensive, but there is also no effective mechanical equipment to quickly separate the impurities from the wood veneer.

A material-pushing roller 15 is installed on the inner side of the frame body 1 at the upper end of the first conveyor belt 2 and the second conveyor belt 14. A blower 11 is installed on the front side of the frame body 1 near the second conveyor belt 14, and a dust collection box 6 is installed on the rear side of the frame body 1 near the second conveyor belt 14. A dust removal box 9 is provided at the lower end of the frame body 1 below the discharge rollers 8, and a dust cover 3 is installed at the upper end of the frame body 1 above the second conveyor belt 14 and the material-pushing roller 15. The dust cover 3 can prevent dust from splashing.

[0020] exist Figure 2 and Figure 3 In this system, a geared motor 4 is installed at the input end of conveyor belt 2, which drives conveyor belt 2 to move, thus conveying the waste wood veneer placed on conveyor belt 2 towards the feeding roller 15. A geared motor 5 is installed at the input end of feeding roller 15, which drives feeding roller 15 to rotate, thereby breaking up the waste wood veneer on conveyor belt 2 and feeding it onto conveyor belt 24. A geared motor 7 is installed at the input end of conveyor belt 24, which drives conveyor belt 24 to move, thereby feeding the waste wood veneer falling onto conveyor belt 24. The material enters the discharge roller 8. A chain wheel assembly 10 is installed at the output end of the geared motor 3 7, and a chain wheel assembly 2 12 is installed between the input ends of two adjacent discharge rollers 8. The lower end of the chain wheel assembly 10 is connected to the input end of one of the discharge rollers 8. While the geared motor 3 7 drives the conveyor belt 2 14 to run, it also drives the chain wheel assembly 10 to run. The chain wheel assembly 10 drives one of the discharge rollers 8 to rotate, thereby driving all the discharge rollers 8 to rotate through the chain wheel assembly 2 12. During the rotation of the discharge rollers 8, the waste wood veneer is sent out, and the internal impurities inside the waste wood veneer are separated.

[0021] exist Figure 2 and Figure 3 In the middle, several paddles 16 are fixedly connected to the outer side of the feeding roller 15. As the feeding roller 15 rotates, the paddles 16 can break up the stacked waste wood veneers and feed them onto the conveyor belt 14. Several teeth 13 are fixedly connected to the outer side of each discharge roller 8. The teeth 13 can increase the friction between the discharge roller and the waste wood veneers, prevent them from slipping during the conveying process, and ensure that the impurities between the waste wood veneers fall smoothly into the impurity removal box 9.

[0022] exist Figure 2 and Figure 4 In the dust collection box 6, there is a dust collection box shell 61. The lower end of the dust collection box shell 61 is provided with a set of sliding grooves 63, and an air outlet 65 is provided on one side of the upper end of the dust collection box shell 61. A discharge plate 62 is slidably connected between the set of sliding grooves 63. Several dust outlet holes 17 are evenly opened between the dust collection box shell 61 and the frame body 1. During the process of the waste wood board being pushed towards the conveyor belt 14 by the feeding roller 15, compressed air is blown into the dust cover 3 by the blower 11. The compressed air pushes the small dust particles between the waste wood board towards the dust outlet holes 17. The compressed gas is blown in the direction of 7 and fed into the dust collection box 61 through the ash outlet 17. The compressed gas is discharged from the air outlet 65. The unloading plate 62 is pulled along the slide 63 to unload the small dust particles in the dust collection box 61. A filter screen 64 is provided on the inner side of the dust collection box 61. An electric cylinder 66 is installed in the middle of the upper end of the dust collection box 61. The output end of the electric cylinder 66 is fixedly connected to the filter screen 64. The electric cylinder 66 drives the filter screen 64 to move downward, which can squeeze the small dust particles to keep them compact and reduce their splashing.

[0023] The working principle of this utility model is as follows: First, start the geared motor 4, which drives the conveyor belt 2 to run; then put the stacked waste wood veneer onto the conveyor belt 2, which transports the waste wood veneer towards the feeding roller 15.

[0024] Then start the second geared motor 5. The second geared motor 5 drives the feeding roller 15 and the feeding plate 16 to rotate together. During the rotation, the feeding plate 16 breaks up the stacked waste wood and board and feeds it onto the second conveyor belt 14.

[0025] Next, start the blower 11. The blower 11 blows compressed air into the dust cover 3. The compressed air blows the small dust particles between the waste wood boards towards the ash outlet 17 and sends the small dust particles into the dust collection box 61 through the ash outlet 17. The compressed gas is discharged after passing through the filter screen 64 and the air outlet 65. Large impurities and the broken waste wood boards fall onto the conveyor belt 14.

[0026] Next, the geared motor 37 is started. The geared motor 37 drives the conveyor belt 214 and the discharge roller 8 to run together. The waste wood and veneer on the conveyor belt 214 falls onto the discharge roller 8. Large particles of impurities fall into the impurity removal box 9 between the two adjacent discharge rollers 8, while the waste wood and veneer is discharged from one end of the discharge roller 8, thereby achieving the purpose of uniform material distribution.

[0027] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
