Description

Technical Field

[0001] The utility model relates to the technical field of particle board dust removal, in particular to a dust removal mechanism of a particle board cutting device. Background Art

[0002] Particleboard, also known as particle board, particle board, and bagasse board, is a man-made board made of wood or other lignocellulosic materials, which is glued together under heat and pressure after applying adhesive. It is also called particle board. It is mainly used in furniture manufacturing, construction industry, and train and car carriage manufacturing. Because particleboard has a relatively uniform structure and good processing performance, it can be processed into large-format boards as needed. It is a good raw material for making furniture of different specifications and styles. The finished particleboard does not need to be dried again and can be used directly. It also has good sound absorption and sound insulation properties.

[0003] A large amount of wood chips will be generated during the processing of particleboard. The wood chips will spread into the air, which will affect the environment of the processing workshop and the health of the workers. The subsequent cleaning will greatly increase the workload of the workers. In addition, the wood chips generated during the processing of particleboard cannot be classified and collected, which is not convenient for subsequent recycling. Therefore, we propose a dust removal mechanism for a particleboard cutting device. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 A dust removal mechanism of a particleboard cutting device in this embodiment includes a cutting table 1, a waste hopper 9 is connected to the inside of the cutting table 1, an infrared sensor 10 is fixedly connected to the inner side of the waste hopper 9, a collecting drawer 11 is movably connected to the inside of the cutting table 1, a separation structure 12 is movably connected to the inside of the collecting drawer 11, and an exciter 13 is fixedly installed inside the cutting table 1;

[0022] The separation structure 12 includes a collection rack 1201, the collection rack 1201 is fixedly arranged inside the collection drawer 11, the first filter 1202 is fixedly connected inside the collection rack 1201, the second filter 1203 is fixedly connected inside the collection rack 1201, and the inner wall of the second filter 1203 is fixedly connected to a support needle 1204.

[0023] In specific implementation, when the infrared sensor 10 is activated, the PN junction inside the infrared diode will emit infrared light. The emitted infrared radiation is usually pulsed, that is, it is emitted at a certain frequency. The emitted infrared radiation will propagate in the air or other media until it encounters an object. The infrared radiation absorbed by the object will cause the temperature of the object to rise, and will also cause the object to emit infrared radiation. The infrared photodiode converts the infrared radiation reflected by the object into current, thereby triggering and turning on the exciter 13.

[0024] The exciter 13 is usually composed of a vibration generator, an elastic element and a mass block. It transmits vibration energy by utilizing mechanical vibration. When the infrared sensor 10 converts infrared radiation into current, direct current is passed into the excitation coil, and then alternating current is passed into the moving coil. The moving coil is driven by the periodically changing electromagnetic excitation force to drive the top rod to reciprocate, thereby driving the collection drawer 11 to oscillate.

[0025] When implementing, follow these steps:

[0026] 1) First, keep the linear motion, place the particle board to be processed on the cutting table 1, and at the same time, the worker can push the particle board into the dust cover 2 with a small force, then start the servo motor 5, and the servo motor 5 drives the roller 7 to rotate in the opposite direction of the particle board, and at this time, the brush 8 also rotates spirally with the rotation of the roller 7;

[0027] 2) Then, the waste is collected. After the brush 8 rotates in a spiral manner, the wood chips and dust on the surface of the particle board are swept by the brush 8 to the two sides of the particle board, and at the same time, they fall into the waste hopper 9 through the spacing of the rollers 7 inside the cutting table 1 to complete the preliminary collection;

[0028] 3) Sensing the waste again, when the waste enters the waste hopper 9, the infrared radiation emitted by the infrared sensor 10 propagates in the air or other media until it encounters the wood chips, and the infrared radiation absorbed by the waste causes the wood chips to increase in temperature, and also causes the wood chips to emit infrared radiation, and the infrared photodiode converts the infrared radiation reflected by the wood chips into electric current, thereby triggering and turning on the exciter 13;

[0029] 4) Finally, the waste is separated. The vibrator 13 drives the collection drawer 11 to oscillate. At this time, the waste falling into the collection drawer 11 is shaken by the vibrator 13, and small particles of dust pass through the second filter 1203 and the first filter 1202 and fall to the bottom wall of the collection drawer 11, while relatively large wood chips flow inside the collection rack 1201. After the dust removal is completed, the worker can open the collection drawer 11 and classify the two types of waste particles for secondary utilization.

[0030] In summary, the dust removal mechanism of the particleboard cutting device, by setting a separation structure 12 and coordinating with the linkage design of the double filter screen, can filter and classify the collected wood chips, which is convenient for later recycling. Then, under the vibration action of the vibrator 13 of the collection drawer 11, the filtering effect of the wood chips can be improved to avoid clogging of the filter screen.

[0031] Furthermore, by providing the rollers 7 and the brushes 8, when the particle board is placed between the two groups of rollers 7 and moves, the upper group of rollers 7 can drive the particle board to move forward and keep the moving path centered, so that the particle board can keep moving straight during the cleaning process, and avoid the particle board from tilting and falling off the cutting table 1. At the same time, with the spirally distributed brushes 8, the particle board can be cleaned in the reverse direction, and it is ensured that the wood chips and dust on the surface of the particle board are not missed. At the same time, the resistance of the particle board during movement can be reduced, and the stains and dust remaining on the particle board can be completely cleaned, thereby increasing the cleaning efficiency and dust removal efficiency.
