Description

Technical Field

[0001] The invention relates to the technical field of granulators, in particular to a swing granulator. Background Art

[0002] The swing granulator is a device that makes the mixed powder or block dry material into the required granules. In the production of dairy products, the swing granulator can be used to make powdered raw materials such as milk powder into granules for easy storage and transportation. This granulator uses the forward and reverse rotation of the rotating drum to grind the wet powder or block dry material into the required granules through the screen.

[0003] During operation, the swing granulator imitates manual rubbing and pressing of the screen, allowing the soft material to pass through the screen, resulting in the screen being subjected to extrusion pressure. At the same time, the material is concentrated at the lowest point of the screen under the action of gravity, and the stress of the screen is also concentrated at its lowest point during operation. Under alternating loads, although the stress on the screen is lower than its yield point, the screen at the lowest part has always been at the lowest point without changing its position. After a long period of operation, this part of the screen will crack or suddenly break, affecting the service life of the screen. Summary of the invention

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example 1: Reference Figure 1-8 A swing granulator comprises a chassis 1, to which a feed hopper 2 is fixedly connected, to which a swing assembly 10 is rotatably connected via a bearing, and the swing assembly 10 is transmission-connected to the chassis 1, to which two clamping rods 3 are rotatably connected via a bearing, a screen 4 is fixedly connected between the two clamping rods 3, and the screen 4 can be wound around the two clamping rods 3, and both ends of the screen 4 are in contact with the feed hopper 2. The swing assembly 10 is driven to rotate back and forth by a driving assembly in the chassis 1, thereby forming pressure and shearing force on the material, and the material is squeezed out of the screen 4 for granulation and cut.

[0029] The two clamping rods 3 are connected to the first gear 12, the swing assembly 10 is coaxially fixedly connected to the connecting shaft 8, the connecting shaft 8 is connected to the second gear 19, and the second gear 19 is respectively meshed with the two first gears 12. When working, the swing assembly 10 swings back and forth, driving the connecting shaft 8 to rotate, so that the second gear 19 drives the two first gears 12 to rotate, and the rotation directions of the two first gears 12 are the same. Figure 5 As shown, one of the clamping rods 3 is used to reel in the screen 4, while the other clamping rod 3 is used to loosen the screen 4, thereby ensuring that the length of the screen 4 remains unchanged during operation. At the same time, the position of the screen 4 at the lowest point is changed, so that the screens 4 at different positions are subjected to the stress load at the lowest point, thereby avoiding the stress load at the same position that is always at the lowest point, thereby increasing the service life of the screen 4.

[0030] The number of teeth of the second gear 19 is greater than that of the first gear 12 , so that the clamping roller 3 can rotate at a reduced speed, so that the clamping roller 3 can slowly roll up and unwind the screen 4 .

[0031] Example 2: In Example 1, since the length of the screen 4 is fixed during operation and cannot be changed, the tightness of the screen 4 cannot be changed. The tightness of the screen 4 has an effect of adjusting the coarseness, looseness and tightness of the particles. However, in Example 1, the tightness of the screen 4 cannot be adjusted, which affects the quality of the particles. Figure 1-11 , as another preferred embodiment of the present invention, based on Example 1.

[0032] The screen 4 is adjusted by a tension adjustment mechanism, which includes a rack 13. The two first gears 12 are fixedly meshed with racks 13, and the two racks 13 are fixedly connected to a connecting frame 21. The two connecting frames 21 are positioned by a positioning mechanism. When the first gear 12 rotates, the two racks 13 will be driven to move. Since the first gear 12 rotates back and forth, the two racks 13 will be driven to move back and forth. Since the two first gears 12 have the same rotation direction, the two racks 13 run in opposite directions or move toward each other. The position of the connecting frame 21 on the limit rod 22 is adjusted. When the first gear 12 and the second gear 19 are transmitted, the rack 13 does not disengage from the first gear 12. When adjusting the tightness of the screen 4, there is no need to re-engage the rack 13 with the first gear 12, which is conducive to the convenience of operation.

[0033] The two first gears 12 are respectively sleeved on the clamping rods 3, and the two clamping rods 3 are fixedly connected with connecting edges 18. The two first gears 12 are provided with connecting grooves, and the two connecting edges 18 are slidably arranged in the connecting grooves. The two first gears 12 are fixedly connected with springs 16. When the tightness of the screen 4 is adjusted, the two clamping rods 3 need to rotate in opposite directions. The connecting edges 18 and the connecting grooves play a limiting role on the first gears 12 so that the first gears 12 and the clamping rods 3 rotate synchronously. At the same time, the first gear 12 can move to disengage from the meshing with the second gear 19, and release the transmission limit of the second gear 19 on the two first gears 12, so that the two first gears 12 can rotate in opposite directions under the action of the rack 13 to adjust the tightness of the screen 4.

[0034] Two springs 16 are fixedly connected to the fixed block 17, and the spring 16 is used to reset the first gear 12. The two fixed blocks 17 are fixedly connected to the clamping rod 3 respectively. The connecting ear 31 is fixedly connected to the feed hopper 2. The connecting ear 31 is threadedly connected with a threaded rod 32. The threaded rod 32 is rotatably connected with a movable seat 29 through a bearing. A limiting column 27 is provided on the movable seat 29. The limiting column 27 connects the movable seat 29 and the abutment plate 20. The limiting column 27 is fixedly connected with the abutment plate 20. The relative inner sides of the two connecting frames 21 are fixedly connected with vertical edges 28. The two vertical edges 28 are fixedly connected to the two connecting frames 21. The edge 28 can be abutted against the abutment plate 20 through the abutment mechanism, and the abutment plate 20 is abutted against the vertical edge 28 through the abutment mechanism. When the threaded rod 32 is rotated, the moving seat 29 will be driven to move. At the same time, due to the friction between the abutment plate 20 and the vertical edge 28, the two vertical edges 28 are moved at the same time, driving the two racks 13 to move in the same direction, and driving the two first gears 12 to rotate in opposite directions, so as to adjust the tightness of the screen 4 and ensure that the quality of the particles is not affected. When granulating, the abutment plate 20 does not abut against the vertical edge 28, so that the vertical edge 28 can move with the movement of the rack 13.

[0035] The positioning mechanism includes a limit rod 22, which is fixedly connected to the feed hopper 2 and passes through the connecting frame 21. The limit rod 22 limits the connecting frame 21, thereby preventing the connecting frame 21 from rotating and deviating.

[0036] Example 3: In Example 2, the driving mechanism of the swing-type pellet machine is driven by a motor, a V-belt pulley, a worm gear, and the eccentric crankshaft and the lifting rack make the swing assembly of the gear shaft belt perform periodic reciprocating rotation. Due to the self-locking property of the worm gear and the worm, the swing assembly 10 cannot be rotated by external force after stopping. In Example 2, after the tightness is adjusted, in order to ensure the tightness of the screen 4, the clamping rod 3 cannot be rotated at will, and the second gear 19 cannot be rotated, so that the gear teeth of the first gear 12 are aligned with the tooth grooves of the second gear 19. When re-engaging, it increases the difficulty of re-engaging the first gear 12 with the second gear 19, which is not conducive to the convenience of operation. Figure 1-11As another preferred embodiment of the present invention, on the basis of embodiment 2, the second gear 19 is rotatably connected to the connecting shaft 8 through a bearing, a cavity 30 is provided on the connecting shaft 8, a plurality of conducting tubes 26 are fixedly connected to the connecting shaft 8 at equal distances on the circumference, the plurality of conducting tubes 26 are all connected to the cavity 30, a piston 14 is abutted in the plurality of conducting tubes 26, abutting columns 33 are fixedly connected to the plurality of pistons 14, a connecting ring 25 is fixedly connected to the second gear 19, a plurality of abutting columns 33 can abut the connecting ring 25, the cavity 30 is rotatably connected to the connecting pipe 11 through a sealed bearing, an air pump 9 is connected to the connecting pipe 11, the air pump 9 is fixedly connected to the feed hopper 2, a connecting plate 5 is fixedly connected to the piston rod of the air pump 9, a telescopic rod 6 is fixedly connected to the connecting plate 5, the telescopic rod 6 is fixedly connected to the feed hopper 2 The fixed connection is achieved by contracting the telescopic rod 6, which squeezes the air in the air pump 9 into the cavity 30. The air pushes the piston to move, moves the abutment column 33, and abuts the abutment column 33 on the connecting ring 25, so that the second gear 19 is connected to the connecting shaft 8, so that the connecting shaft 8 drives the second gear 19 to rotate. When the tightness of the screen 4 needs to be adjusted and the connecting shaft 8 and the second gear 19 do not need to be connected, the telescopic rod 6 is extended, the pressure in the cavity 30 is reduced, and the abutment column 33 does not abut against the connecting ring 25, so that the second gear 19 can rotate. The second gear 19 is manually rotated so that the tooth groove of the second gear 19 is aligned with the gear teeth of the first gear 12. After the first gear 12 moves and resets, it will mesh with the second gear 19 again, which is conducive to the convenience of operation.

[0037] The abutment mechanism includes a limiting portion 23, which is fixedly connected to the connecting plate 5. A limiting sleeve 24 is fixedly connected to the abutment plate 20, and the limiting portion 23 can be inserted into the limiting sleeve 24. When the telescopic rod 6 is extended, the connecting plate 5 will be driven to move, so that the abutment plate 20 abuts against the vertical edge 28, so that the threaded rod 32 can be rotated to drive the vertical edge 28 to move, and at the same time, the position of the limiting portion 23 in the limiting sleeve 24 is adjusted, thereby driving the rack 13 to move. When the telescopic rod 6 is retracted, the movement of the abutment plate 20 will release the abutment against the vertical edge 28, which is beneficial to the convenience of operation. There is no need to manually operate the abutment plate 20 to move, abut or relax the vertical edge 28.

[0038] Two connecting parts 7 are fixedly connected to the connecting plate 5, and movable sleeves 15 are rotatably connected to the two connecting parts 7 through bearings. The two movable sleeves 15 are respectively sleeved on the two clamping rods 3, and the two movable sleeves 15 are respectively in contact with the two first gears 12. When the telescopic rod 6 is extended, the movable sleeve 15 will be driven to move, so that the movable sleeve 15 drives the first gear 12 to move, and the first gear 12 is disengaged from the second gear 19. When the telescopic rod 6 is retracted, the first gear 12 will be moved and reset under the action of the spring 16. When the first gear 12 is disengaged from the second gear 19, no manual operation is required, which is conducive to the convenience of operation and safety.

[0039] When working: the driving assembly in the chassis 1 drives the swing assembly 10 to rotate back and forth to perform granulation. At the same time, when the swing assembly 10 swings back and forth, it drives the connecting shaft 8 to rotate, so that the second gear 19 drives the two first gears 12 to rotate, which will cause one of the clamping rods 3 to reel in the screen 4 and the other clamping rod 3 to loosen the screen 4, so that the position of the screen 4 located at the lowest point is changed; when the tightness of the screen 4 needs to be adjusted, the telescopic rod 6 is extended, and the piston rod of the air pump 9 moves, so that the air in the cavity 30 enters the air pump 9, and the pressure in the cavity 30 is reduced. Under the action of air pressure, the abutment column 33 will not abut against the connecting ring 25, which will allow the second gear 19 to rotate. At the same time, when the telescopic rod 6 is extended, it will drive the connecting plate 5 to move, so that the abutment plate 20 abuts on the vertical edge 28, and drive the movable sleeve 15 to move, so that the movable sleeve 15 drives the first gear 12 The first gear 12 is disengaged from the second gear 19, and then the threaded rod 32 is rotated to drive the vertical edge 28 to move, and the vertical edge 28 drives the two racks 13 to move in the same direction, driving the two first gears 12 to rotate in opposite directions, thereby adjusting the tightness of the screen 4; after the adjustment is completed, the second gear 19 is rotated to align the tooth groove of the second gear 19 with the gear teeth of the first gear 12, and then the telescopic rod 6 is contracted to drive the connecting plate 5 to move, so that the air in the air pump 9 is squeezed into the cavity 30, and the air pushes the piston to move, and the abutment column 33 is moved, and the abutment column 33 is abutted on the connecting ring 25, which will connect the second gear 19 with the connecting shaft 8. At the same time, the movement of the abutment plate 20 will release the abutment against the vertical edge 28, and the first gear 12 will be moved and reset under the action of the spring 16, and the first gear 12 and the second gear 19 are re-engaged, and the motor is restarted for re-granulation.
