The large-scale digital powder forming machine has the beneficial effects that:
the large digital powder forming machine is used for forming powder in the process and working principle that: starting a driving device, rotating a driving roller, then throwing powder, at the moment, enabling the powder to fall into the contact position of the driving roller and a driven roller, extruding the fallen powder when the driving roller rotates, and enabling the driven roller to rotate at a speed slightly lower than the rotating speed of the driving roller under the action of contact friction force between the powder and the driven roller, so that the powder is extruded and molded in a cavity; then, the molded coal products after extrusion molding fall down to be output; meanwhile, after the powder is molded by the driving roller and the driven roller, the powder and the powder respectively pass through the first anti-adhesion device and the second anti-adhesion device in the process of continuing to rotate so as to scrape the surfaces of the driving roller and the driven roller, thereby removing residual powder attached to the surfaces of the driving roller and the driven roller, further ensuring the surface smoothness of the driving roller and the driven roller, and preparing for subsequent molding. When the molded coal products with different sizes are required to be processed, the position of the driven roller can be adjusted, so that the driven roller moves relative to the driving roller in the radial direction, the thickness degree of the cavity is controlled, and the molded coal products with different sizes are obtained.
The principle and the process that this adjusting part is used for adjusting the driven voller position are: the adjusting bolt is screwed, the driven roller bearing seat slides leftwards relative to the frame under the action of the adjusting bolt, and at the moment, the driven roller moves towards the direction of the driving roller; after the driven roller moves in place, the cushion block is clamped in a gap formed between the driven roller bearing seat and the frame, and at the moment, under the combined action of the cushion block and the adjusting bolt, the driven roller bearing seat is stably limited to ensure the normal operation of the driven roller. When the powder falling into the cavity is too hard or too much, the drive roller and the driven roller will be subjected to pressing forces in respective radial directions and opposite directions, namely: the drive roller bearing housing and the driven roller bearing housing will be subjected to pressing forces in respective radial directions and in opposite directions. According to the transmission of force, the extrusion force on the driven roller bearing seat is transmitted to the pin, and the pin is deformed under the action of the extrusion force because the pin is axially limited under the combined action of the driven roller bearing seat and the frame. The working condition adjustment of the driving roller and the driven roller at the moment can be judged by observing the state of the pin by a worker, and if the pin is deformed, the machine is stopped for maintenance.
According to the large digital powder forming machine, the driving roller and the driven roller are arranged to be high and low, when the driving roller and the driven roller are gradually separated from a contact state, powder can be separated from the upper press roller by utilizing the gravity of the powder in the forming process, the powder is attached to the lower press roller, and molded coal is completely separated from a cavity in the continuous rotation process of the lower press roller, so that the molded coal falls. And because the rotation speed of the driving roller is slightly larger than that of the driven roller, the stress at the contact part of the molded coal product and the driving roller and the driven roller is asymmetric, so that the material contention situation between the driving roller and the driven roller is reduced, and the molding reliability of powder is ensured.
Through setting up the pin for the inside operational aspect of equipment can be in time known to the outside staff of equipment, has avoided to a certain extent because of the powder is too hard or too much and the destruction that causes drive roll bearing frame and driven roll bearing frame, has reduced maintenance cost. And after the pin is deformed, the pin can be replaced by rotating the adjusting bolt after the shutdown maintenance is completed, so that the protection of the bearing is continuously realized, the operation is convenient, the cost is low, and the high market economic value is realized.
By arranging the first anti-adhesion device and the second anti-adhesion device, the powder adhered to the surfaces of the driving roller and the driven roller is scraped, the adhesion of the powder is reduced, and the reliability of the subsequent forming process is ensured. And the radial relative positions of the driving roller and the driven roller are adjusted, so that the regulation of the specifications of the mold cavity is realized, the processing of molded coal products with different specifications is realized, the product style is increased, the processing and the manufacturing of various molded coal products can be finished by using the same large-scale digital powder molding machine, and the functional requirements of workshop production on the large-scale digital powder molding machine are greatly met. In addition, the large-scale digital powder molding machine is simple in structure, easy to realize in scheme, low in cost and significant in powder processing production.
The second object of the invention is to provide a powder processing device to solve the technical problem of inconvenient output of the processed molded coal products.
The powder processing equipment provided by the invention comprises the large digital powder forming machine and a conveying device for outputting molded coal products produced by the large digital powder forming machine.
The conveying device comprises a conveying assembly and a transmission assembly used for transmitting power to the conveying assembly, the conveying assembly comprises a first conveying roller and a second conveying roller which are pivoted with the frame, a synchronous conveying belt is arranged between the first conveying roller and the second conveying roller and used for outputting molded coal products to the outside of the large-scale digital powder molding machine, the transmission assembly comprises a driving wheel and a driven wheel, the driving wheel is synchronously rotated with the driving roller, the driven wheel is synchronously rotated with the first conveying roller, and a synchronous conveying belt is arranged between the driving wheel and the driven wheel.
When the driving roller rotates, the driving wheel synchronously rotates, the driving belt transmits rotation power to the driven wheel, and the first conveying roller is driven to rotate so as to convey the molded coal products.
The powder processing equipment has the beneficial effects that:
accordingly, the powder processing apparatus has all the advantages of the above-mentioned large-sized digital powder forming machine, and will not be described herein.
When the driving roller rotates, the driving wheel synchronously rotates along with the driving roller, and then power is output to the driving belt to drive the first conveying roller to rotate, so that the conveying belt can transport molded coal products. After the powder is extruded and molded in the cavity between the contact surfaces of the driving roller and the driven roller, the molded coal product falls onto the conveying belt from the cavity, and is finally output to the outside of the large-scale digital powder molding machine along with the continuous forward conveying of the conveying belt for subsequent processing. Through setting up conveyer, can in time export the moulded coal after the shaping, reduce the piling up of moulded coal product in large-scale digital powder make-up machine, guaranteed normal production.

The principle and process of the adjusting assembly 60 for adjusting the position of the driven roller 41 are as follows: the adjusting bolt 63 is screwed, and the driven roller bearing seat 42 slides leftwards relative to the frame 10 under the action of the adjusting bolt 63, and at this time, the driven roller 41 moves towards the driving roller 31; when the driven roller 41 moves in place, the cushion block 65 is clamped in a gap formed between the driven roller bearing seat 42 and the frame 10, and at this time, under the combined action of the cushion block 65 and the adjusting bolt 63, the driven roller bearing seat 42 is stably limited to ensure the normal operation of the driven roller 41.
When the powder falling into the cavity is too hard or too large, the driving roller 31 and the driven roller 41 will be subjected to pressing forces in respective radial directions and opposite directions, namely: the drive roller 31 bearing housing and the driven roller bearing housing 42 will receive pressing forces in respective radial directions and in opposite directions. According to the transmission of the force, the pressing force on the driven roller bearing housing 42 is transmitted to the stud 62, and since the stud 62 has achieved the axial limit at this time by the combined action of the driven roller bearing housing 42 and the frame 10, the stud 62 is deformed by the pressing force. By observing the state of the pin 62, a worker can judge the condition adjustment of the driving roller 31 and the driven roller 41 at the moment, and if the pin 62 deforms, the machine is stopped for maintenance.
According to the large-scale digital powder forming machine, the driving roller 31 and the driven roller 41 are arranged to be high or low, when the driving roller 31 and the driven roller 41 are gradually separated from a contact state, powder can be separated from the upper press roller by utilizing the gravity of the powder in the forming process and is attached to the lower press roller, and molded coal is completely separated from a cavity in the continuous rotating process of the lower press roller, so that the molded coal falls off. And, because the rotational speed of the driving roller 31 is slightly greater than the rotational speed of the driven roller 41, the stress at the contact part of the molded coal product and the driving roller 31 and the driven roller 41 is asymmetric, thereby reducing the material contention situation between the driving roller 31 and the driven roller 41 and ensuring the molding reliability of the powder.
By arranging the pins 62, the working conditions inside the equipment can be known in time by workers outside the equipment, damage to the driving roller bearing seat 32 and the driven roller bearing seat 42 caused by excessive or too hard powder is avoided to a certain extent, and the maintenance cost is reduced. And, after the pin 62 takes place the deformation, through rotating adjusting bolt 63 after the shut down overhauls and accomplish, can realize the change to the pin 62 to continue to realize the protection to bearing frame, not only convenient operation, and the cost is lower, has higher market economic value.

And, through adjusting the radial relative position of the driving roller 31 and the driven roller 41, the adjustment of the specifications of the mold cavity is realized, and then the processing of molded coal products with different specifications is realized, and the product style is increased, so that the processing and the manufacturing of various molded coal products can be completed by using the same large-scale digital powder molding machine, and the functional requirements of workshop production on the large-scale digital powder molding machine are greatly met.
