Technical Field
[0001] The present invention relates to the technical field of particle forming, and in particular to a particle forming device with passive pressure wheel power transmission assistance. Background Art
[0002] The pellet machine is used to grind wet powder into the required particles, and can also crush block dry materials into the required particles. It is the process of processing material particles into solid objects of different shapes and sizes under specific conditions. The main features are easy installation and disassembly of the screen, and the tightness can be adjusted appropriately. It is easy to disassemble and clean. Commonly used particle forming methods include pressing, extrusion, injection molding, etc. Pellet forming technology is widely used in aviation, shipbuilding, automobile, construction and other fields. Its principle is to use bonding force and compression force to produce adsorption between material particles and form a solid structure. As we all know, pellet machines are divided into two series - flat die series and ring die series. You should be familiar with the ring die series because many feed companies at home and abroad use ring die machines for pelleting. The raw materials for feed are all fine materials, such as corn, soybean meal, cottonseed meal, etc., with high bonding rate. In addition, a steam conditioner is equipped before pelleting, which can soften and mature the material in advance, so as to make better pellets and increase the gloss of the pellets. However, crude fibers such as straw and sawdust have low bonding rate and are difficult to form. If used as fuel pellets, the required density is very high, so a lot of pressure is required to achieve the density of the pellets, which invisibly increases the difficulty. Since renewable energy has gradually emerged in recent years, the ring die pellet machines for fuel pellets promoted on the market are evolved from the ring die machines for feed; the pellet machine is composed of a main body, a pellet manufacturing device and a reduction box; Among them, the main body: the machine body is an independent rectangular column, on which a closed bearing seat is installed to connect with the powder hopper, the powder hopper extends out of the machine body, and a V-shaped chassis is installed below it, with a wide and flat ground surface, so it does not need to be installed below, and can be placed indoors for use at will; particle manufacturing device: the rotating drum is placed horizontally under the powder hopper, with bearing supports at the front and back, it is driven by the rack to make forward and reverse rotation, the front bearing cover on the end face is movable, when assembling and disassembling, just unscrew a wing nut, the bearing cover and the rotating drum can be pulled out, and convex square rings are made at both ends of the placement drum, which are embedded in the bearing room, so that oil and dirt will not penetrate into the powder and will not stick and clog; reduction box: it adopts worm gear drive, the speed ratio is 1:12, and the box can store engine oil , ensure that the gears are well lubricated and free of noise. There is a sight glass on the box for observation, to observe the operating conditions and oil storage. The outer end of the worm gear is equipped with an eccentric shaft, which drives the rack to reciprocate. Check the machine parts regularly, once a month, to check whether the worm gear, worm, bolts and bearings on the lubrication block and other active parts are flexible or whether there is any wear. If defects are found, they should be repaired in time and should not be used reluctantly. The machine should be placed in a dry and clean room for use. It should not be used in places where the atmosphere contains acids and other gases that are corrosive to the machine body. After the machine is used or stopped, the rotating drum should be taken out for cleaning and the remaining powder in the bucket should be brushed clean, and then installed properly to prepare for the next use.
[0003] There are two types of biomass pellet forming equipment on the market, one vertical and one horizontal. Regardless of which type of pellet forming equipment, it mainly relies on pressing pellets to form pellets. Both use an active pressing wheel to drive a passive pressing wheel for pressing and forming. There is no power input to the passive pressing wheel. If the moisture content of the raw material is high, the gap between the active wheel and the passive wheel is not adjusted properly, or the original tooth surface of the passive pressing wheel is worn, the passive pressure wheel will slip, resulting in machine blockage or machine jam, and normal production cannot be achieved. Summary of the invention
[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a particle forming device with passive pressure wheel power transmission assistance. The original passive pressure relying purely on friction is converted into a passive pressure wheel after installing a power transmission assistant. When the passive pressure wheel is working, the power is automatically switched between active and passive. When the friction resistance between the original active pressure wheel and the passive pressure wheel is insufficient, the power assistant intervenes to transmit power, changing from the original passive to active. When the friction resistance is sufficient, the auxiliary power stops intervening and becomes passive. The device automatically switches again during the action process, effectively avoiding the original passive pressure wheel slipping phenomenon. The power input shaft and the power output shaft are configured with a torque limit adjustment for the power input shaft, and the torque input value can be set to protect the input power. When the output torque suddenly increases, the power input end fails and slips. The power output shaft is configured with a unidirectional power input mechanism. When the speed of the internal output shaft sleeve exceeds the speed of the external output shaft sleeve, the unidirectional power fails. When the speed of the internal output shaft sleeve is lower than that of the external output shaft sleeve, the unidirectional power is enabled to transmit power to the internal output shaft sleeve, thereby satisfying the power assistance function, improving production efficiency and other advantages, and solving the problem of slipping of the device.

[0010] Through the above technical solution, since the side surface of the input shaft is sleeved with a copper sleeve, the side surface of the sprocket is provided with a pressure plate, and the pressure plate fits with the copper sleeve and separates under the action of the roller. At this time, the power of the input shaft disengages from the internal output sleeve, and the internal output sleeve becomes passively rotated.

The present invention converts the original passive pressure relying purely on friction into a passive pressure wheel after installing a power transmission auxiliary device. When the present invention is working, the power is automatically switched between active and passive.

The automatic switching during the action again effectively avoids the slippage of the original passive pressure wheel. The power input shaft and the power output shaft are configured with a torque limit adjustment for the power input shaft, and the torque input value can be set to protect the input power.
