Description

Technical Field

[0001] The invention relates to the technical field of granulation equipment, in particular to a continuous granulator. Background Art

[0002] In the pharmaceutical, food and chemical industries, it is often necessary to process wet powder raw materials into granular finished products or semi-finished products. This process is currently basically carried out by a swing granulator.

[0003] For example, Chinese patent CN218981462U discloses a swing type pellet machine, which drives a rotating drum to rotate back and forth through a driving member, and reciprocates and rolls the raw materials on the filter screen, so that the raw materials are forced to pass through the filter screen to form the desired particles.

[0004] The swing pellet machine adjusts the forward and reverse directions of the rotating drum through the driving part to achieve reciprocating pushing and grinding of the raw materials; however, when the rotating direction of the rotating drum is forcibly changed, the rotating drum will generate impact force due to inertia (when the rotating drum changes from forward rotation to reverse rotation, the rotating drum has a continuous forward rotation impact force due to inertia when the forward rotation stops), and the impact force will be transmitted to the working chassis and related driving parts. After long-term use, it is easy to damage the supporting stability of the working chassis, and at the same time, it will cause stress damage to related driving parts, causing damage to the equipment; thus making it difficult to scale up the device; In addition, the forced change of the rotating direction of the rotating drum requires the rotating rolling speed to be accelerated in the reverse direction. Frequent deceleration and acceleration consumes a lot of energy. At the same time, there are stop gaps when the equipment alternates between forward and reverse rotation, which affects manufacturing efficiency.

[0028] After the filter screen 4 transported by the feed roller 512 is guided by the left guide roller 514, it passes between the first fastening roller 611 and the rotating sleeve roller 617 on the left, and is pressed by the first fastening roller 611 and the rotating sleeve roller 617. Then the filter screen 4 bypasses the lower side of the pressure roller 622 and the support roller 623, and then the filter screen 4 passes between the two shaping rollers 515 and the bottom of the processing box 12 in turn. Then the filter screen 4 bypasses the pressure roller 622 and the support roller 623 on the right, passes between the first fastening roller 611 and the rotating sleeve roller 617, bypasses the guide roller 514 on the right, and is finally wound up by the winding roller 513.

[0029] In this embodiment, the filter screen 4 is clamped by the first fastening roller 611 and the rotating sleeve roller 617, and the winding roller 513 is wound to tighten the filter screen 4. The tension of the filter screen 4 pushes the support roller 623 to the side, and the support roller 623 drives the tripod 621 to rotate around the center of the mounting rod 624. The rotation of the tripod 621 drives the pressure roller 622 to rotate, so that the pressure roller 622 is pressed against the first fastening roller 611; at the same time, the ratchet 614 is inserted into the gear teeth of the ratchet wheel 613 under the push of the spring 615, so that the ratchet wheel 613 can only rotate in one direction, so that the first fastening roller 611 fixedly connected to the ratchet wheel 613 can only rotate in one direction; so that when the fixed grinding roller 322 and the rotating grinding roller 323 cooperate with the filter screen 4 to push and grind the raw materials, the processing box 12 The force generated by the filter screen 4 on the lower side pulls the second fastening roller 612, and the second fastening roller 612 cannot rotate under the cooperation of the ratchet 613, the pawl 614 and the spring 615, thereby preventing the force generated by the filter screen 4 on the lower side of the processing box 12 from being directly transmitted to the feeding roller 512 and the winding roller 513, causing impact on the feeding roller 512 and the winding roller 513; and the structure composed of the ratchet 613, the pawl 614 and the spring 615 has a slight reverse rotation, and when the filter screen 4 is tensioned, the first fastening roller 611 is pressed by the pressing roller 622, thereby compensating for the slight reverse rotation of the structure composed of the ratchet 613, the pawl 614 and the spring 615, so that the filter screen 4 between the first fastening rollers 611 on both sides is more tightened; After being used for a period of time, the filter screen 4 is deformed, so that the filter screen 4 between the first fastening rollers 611 is no longer tensioned, and the pressure roller 622 no longer presses the first fastening roller 611. At this time, the structure composed of the ratchet 613, the pawl 614 and the spring 615 prevents the first fastening roller 611 from rotating to one side, thereby cooperating with the rotating sleeve roller 617 to press the filter screen 4, and also prevents the force generated by the filter screen 4 on the lower side of the processing box 12 from being directly transmitted to the feeding roller 512 and the winding roller 513, causing impact on the feeding roller 512 and the winding roller 513; and at this time, the winding roller 513 drives the filter screen 4 to be wound, and the filter screen 4 drives the first fastening roller 611 to rotate, so that the filter screen 4 between the first fastening rollers 611 on both sides is tensioned again, and the pressure roller 622 presses the filter screen 4 on the first fastening roller 611; When the filter screen 4 at the lower side of the processing box 12 needs to be replaced, if it is blocked or deformed, in order to facilitate replacement, the electric push rod 635 is started to drive the moving block 634 to move downward, and the moving block 634 drives the connecting rods 633 on both sides to move a distance, and then the ends of the slots 636 contact the mounting blocks 616 to drive the mounting blocks 616 on both sides to move, and the mounting blocks 616 drive the pawl 614 to rotate, so that the pawl 614 is disengaged from the ratchet 613, and the spring 615 is stretched; in this process, the movement of the mounting block 616 drives the fixing rod 631 to move, and the fixing rod 631 moves through the hook plate 632 at the end to drive the unlocking rod 6 25 moves, the unlocking rod 625 moves and drives the tripod 621 to rotate around the center of the mounting rod 624, thereby driving the pressure roller 622 and the support roller 623 to rotate, so that the pressure roller 622 is separated from the first fastening roller 611, so that the filter 4 can be quickly rolled up; after the filter 4 on the lower side of the processing box 12 is replaced, the electric push rod 635 drives the moving block 634 to reset, and the moving block 634 drives the connecting rod 633 to move a distance, and the giving groove 636 is no longer in contact with the mounting block 616, and the spring 615 is reset, driving the mounting block 616 and the pawl 614 to reset, so that the pawl 614 is stuck in the ratchet 613.
