Description

Technical Field

[0001] This utility model relates to the field of defoaming masterbatch processing technology, specifically a crushing and granulating machine for defoaming masterbatch. Background Technology

[0002] Defoaming masterbatch is an additive used in the plastics processing process, primarily to eliminate air bubbles or foam formed during processing. It typically consists of active ingredients and a plastic matrix. By being added during processing, it effectively reduces or eliminates foam, ensuring a smooth surface and eliminating bubble defects in the final product.

[0003] In the processing of defoaming masterbatch, the use of a crushing and granulating machine is mainly to ensure that the particle size and quality of the masterbatch meet processing requirements. During the production process, defoaming masterbatch may form large and uneven particles. The crushing and granulating machine can crush large particles into smaller and more uniform particles, ensuring the consistency of the product particle size. However, long-term storage of defoaming masterbatch may cause clumping due to moisture absorption or increased intermolecular forces. When clumped masterbatch enters the crushing and granulating machine, due to the uneven hardness and particle size distribution of the clumps, the shearing and impact forces of the crushing mechanism may not be fully utilized, making it difficult to ensure uniform particle size distribution during the crushing process. Some masterbatch cannot be effectively cut or separated into uniform particles. In subsequent processes, operators need to manually screen and pick out the unevenly crushed defoaming masterbatch for reprocessing. This process not only increases the workload of workers but also reduces overall production efficiency and process stability.

[0004] Therefore, those skilled in the art have provided a crushing and granulating machine for defoaming masterbatch to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a crushing and granulating machine for defoaming masterbatch to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A crushing and granulating machine for defoaming masterbatch includes a granulator shell, a crushing mechanism, and a circulating feeding mechanism. A dispersing box is fixedly connected to the upper end face of the granulator shell. A limiting seat is fixedly connected to the outer wall of one end of the granulator shell. A conveying pipe is fixedly connected inside the limiting seat. A return pipe is passed through and fixedly connected to the upper end face of the conveying pipe. The other end of the return pipe passes through the dispersing box. A crushing mechanism is installed inside the dispersing box and the granulator shell. A circulating feeding mechanism is installed inside the conveying pipe. A feed pipe is passed through and fixedly connected to the bottom end of the conveying pipe. A feed box is fixedly connected to the feed pipe after it passes through the granulator shell.

[0008] As a further embodiment of this utility model: the first crushing roller and the second crushing roller are rotatably connected to the dispersing box, and multiple sets of extension rods are fixedly connected to the outer wall of the rotation rod. The multiple sets of extension rods are arranged at equal intervals, and a dispersing plate is fixedly connected to the other end of each extension rod.

[0009] As a further embodiment of this utility model: a servo motor is fixedly connected to the outer wall of one end of the dispersing box. The power output end of the servo motor passes through the dispersing box and is fixedly connected to the rotating rod. A first transmission rod is fixedly connected to the other end of the rotating rod. A first crushing roller and a second crushing roller are rotatably connected inside the granulator housing. The first crushing roller and the second crushing roller are arranged horizontally and mesh with each other. A transmission gear is fixedly connected to one end of both the first crushing roller and the second crushing roller. Both sets of transmission gears are rotatably connected to the inner wall of the granulator housing and mesh with each other.

[0010] As a further embodiment of this utility model: a second transmission rod is fixedly connected to one end of the first crushing roller near the first transmission rod, and a belt drive assembly is provided between the second transmission rod and the first transmission rod.

[0011] As a further embodiment of this utility model: the inner walls of both the left and right ends of the granulator shell are provided with mounting grooves, and the upper and lower ends of the mounting grooves are fixedly connected with reset springs. The other end of the reset springs is fixedly connected with limit plates, and filter plates are movably engaged between multiple sets of limit plates. The filter plates are located at the bottom of the feed box.

[0012] As a further embodiment of this utility model: a linkage rod is rotatably connected to the bottom of the granulator shell, and multiple sets of connecting sleeves are fixedly connected to the outer wall of the linkage rod. Both ends of the connecting sleeves are fixedly connected to striking components, which abut against the filter plates. A second bevel gear is fixedly connected to the linkage rod after it passes through the granulator shell. A first bevel gear is movably connected to the upper end of the second bevel gear. A spiral conveying rod is rotatably connected inside the conveying pipe. The end of the spiral conveying rod is fixedly connected to the first bevel gear. The first bevel gear and the second bevel gear are arranged perpendicularly and mesh with each other. A drive motor is fixedly connected to the outer wall of the granulator shell. The power output end of the drive motor passes through the granulator shell and is fixedly connected to the linkage rod. A discharge trough is opened at the bottom of the granulator shell, and two sets of feeding inclined plates are fixedly connected to the bottom of the granulator shell.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Because it is equipped with a crushing mechanism, the rotating rod is driven by a servo motor to rotate, which in turn drives the extension rod and the dispersing plate on the outer wall to perform circumferential motion. The synergistic effect of multiple sets of extension rods and dispersing plates can evenly disperse the defoaming masterbatch, preventing the defoaming masterbatch from clumping during the processing, thereby ensuring the high efficiency and stability of the processing. After being dispersed, the defoaming masterbatch enters the granulator shell through the rotating rod and transmission device. After the first and second crushing rollers work together, it can be crushed efficiently. Because the second crushing roller rotates in opposite directions to the first crushing roller, they mesh with each other, which can more effectively crush the defoaming masterbatch, ensuring that there are no dead corners in the crushing process and improving the crushing effect.

[0015] 2. Equipped with a circulating feeding mechanism, the continuous vibration generated by the striking component against the filter plate prevents clogging and ensures continuous operation. It also helps the residual defoaming masterbatch on the filter plate move towards the feed box, reducing material blockage caused by accumulation. The vibration causes the incompletely broken defoaming masterbatch remaining on the filter plate to move towards the feed box more quickly and enter the conveying pipe through the feed pipe, avoiding material waste and ensuring that more incompletely broken defoaming masterbatch can re-enter the dispersing box for secondary processing. The operation of the screw conveyor ensures that the unbroken defoaming masterbatch can enter the dispersing box stably and evenly for secondary processing, avoiding incomplete processing caused by uneven or interrupted material conveying.

[0023] Reference Figure 1-4 This embodiment provides a crushing and granulating machine for defoaming masterbatch, including a granulator shell 1, a dispersing box 2, a limiting seat 3, a conveying pipe 4, a servo motor 5, a rotating rod 6, an extension rod 7, a dispersing plate 8, a first transmission rod 9, a first crushing roller 10, a second crushing roller 11, a transmission gear 12, a second transmission rod 13, a belt drive assembly 14, a return pipe 15, a feed pipe 16, a feed box 17, a mounting groove 18, a return spring 19, a limiting plate 20, a filter plate 21, a spiral conveying rod 22, a first bevel gear 23, a second bevel gear 24, a linkage rod 25, and a connecting sleeve 26. The granulator housing 1 includes a striking component 27, a feeding inclined plate 28, and a discharge chute 29. A dispersing box 2 is fixedly connected to the upper end face of the granulator housing 1. A limiting seat 3 is fixedly connected to the outer wall of one end of the granulator housing 1. A conveying pipe 4 is fixedly connected inside the limiting seat 3. A return pipe 15 is passed through and fixedly connected to the upper end face of the conveying pipe 4. The other end of the return pipe 15 passes through the dispersing box 2. A crushing mechanism is provided inside the dispersing box 2 and the granulator housing 1. A circulating feeding mechanism is provided inside the conveying pipe 4. A feed pipe 16 is passed through and fixedly connected to the bottom end of the conveying pipe 4. A feed box 17 is fixedly connected to the feed pipe 16 after it passes through the granulator housing 1.

[0024] Example 2

[0025] Reference Figure 1 , 2This embodiment is based on the previous embodiment, but differs in that the first crushing roller 10 and the second crushing roller 11 are rotatably connected to the dispersing box 2, and multiple sets of extension rods 7 are fixedly connected to the outer wall of the rotation rod 6. The multiple sets of extension rods 7 are arranged at equal intervals, and the other end of each extension rod 7 is fixedly connected to a dispersing plate 8. A servo motor 5 is fixedly connected to the outer wall of one end of the dispersing box 2. The power output end of the servo motor 5 passes through the dispersing box 2 and is fixedly connected to the rotation rod 6. The other end of the rotation rod 6 is fixedly connected to a first transmission rod 9. The granulator housing 1 is rotatably connected to... There is a first crushing roller 10 and a second crushing roller 11, which are arranged horizontally and mesh with each other. One end of each crushing roller 10 and the second crushing roller 11 is fixedly connected to a transmission gear 12. Both sets of transmission gears 12 are rotatably connected to the inner wall of the granulator housing 1 and mesh with each other. The end of the first crushing roller 10 near the first transmission rod 9 is fixedly connected to a second transmission rod 13. A belt drive assembly 14 is provided between the second transmission rod 13 and the first transmission rod 9.

[0026] The defoaming masterbatch is put into the dispersing box 2 and the servo motor 5 is started in advance. The servo motor 5 drives the rotating rod 6 to rotate. The rotating rod 6 drives the multiple sets of extension rods 7 and the dispersing plate 8 on the outer wall to perform circular motion. The multiple sets of extension rods 7 and the dispersing plate 8 evenly disperse the defoaming masterbatch to prevent the defoaming masterbatch from clumping.

[0027] The broken-up defoaming masterbatch enters the granulator housing 1. When the rotating rod 6 rotates, it drives the first transmission rod 9 at the other end to rotate. The first transmission rod 9 drives the second transmission rod 13 to rotate through the belt transmission assembly 14. The second transmission rod 13 drives the first crushing roller 10 to rotate. The first crushing roller 10 drives another set of transmission gears 12 to rotate through the upper transmission gear 12, so that both the second crushing roller 11 and the first crushing roller 10 rotate (the second crushing roller 11 and the first crushing roller 10 rotate in opposite directions and mesh with each other). This process can crush the defoaming masterbatch that has passed through the second crushing roller 11 and the first crushing roller 10.

[0028] Example 3

[0029] Reference Figure 1 , 34. This embodiment is based on the previous embodiment, but differs in that the inner walls of both ends of the granulator housing 1 are provided with mounting grooves 18. Reset springs 19 are fixedly connected to the upper and lower ends of the mounting grooves 18, and limit plates 20 are fixedly connected to the other ends of the reset springs 19. Filter plates 21 are movably engaged between the multiple sets of limit plates 20. The filter plates 21 are located at the bottom of the feed box 17. A linkage rod 25 is rotatably connected to the bottom of the inner part of the granulator housing 1. Multiple sets of connecting sleeves 26 are fixedly connected to the outer wall of the linkage rod 25. A striking component 27 is fixedly connected to the upper and lower ends of the connecting sleeve 26, and the striking component 27 abuts against the filter plate 21. A linkage rod 25 passes through the pellet mill housing 1 and is fixedly connected to a second bevel gear 24. A first bevel gear 23 is movably connected to the upper end of the second bevel gear 24. A spiral conveying rod 22 is rotatably connected inside the conveying pipe 4. The end of the spiral conveying rod 22 is fixedly connected to the first bevel gear 23. The first bevel gear 23 and the second bevel gear 24 are set perpendicularly and mesh with each other. A drive motor is fixedly connected to the outer wall of the pellet mill housing 1. The power output end of the drive motor passes through the pellet mill housing 1 and is fixedly connected to the linkage rod 25. A discharge chute 29 is opened at the bottom of the pellet mill housing 1. Two sets of discharge inclined plates 28 are fixedly connected to the bottom of the inside of the pellet mill housing 1.

[0030] The crushed defoaming masterbatch falls onto the upper end of the filter plate 21. The completely crushed defoaming masterbatch can fall through the filter plate 21 to the bottom of the pelletizing shell 1 and be discharged from the pelletizing shell 1 through the discharge chute 29 at the bottom of the pelletizing shell 1. Both sets of feeding inclined plates 28 can assist the crushed defoaming masterbatch to be discharged through the discharge chute 29 by the slope.

[0031] The defoaming masterbatch remaining on the upper end of the filter plate 21 will move to the lower end by the slope of the filter plate 21 and enter the feed box 17, and then enter the conveying pipe 4 through the feed pipe 16.

[0032] Start the drive motor, which drives the linkage rod 25 to rotate, causing the multiple sets of connecting sleeves 26 on the outer wall and the striking component 27 to move in a circular motion. The striking component 27 continuously strikes the filter plate 21, causing the filter plate 21 to shake up and down. This can prevent the filter plate 21 from clogging and cause the incompletely broken defoaming masterbatch remaining on the upper end of the filter plate 21 to move continuously towards one end of the feed box 17, and enter the feed box 17 more quickly.

[0033] The upper ends of the outer walls at both ends of the filter plate 21 abut against the limiting plate 20. The limiting plate 20 is connected to the mounting groove 18 through the return spring 19, so that when the filter plate 21 shakes, the return spring 19 will deform synchronously and buffer it.

[0034] When the filter plate 21 needs to be replaced, the filter plate 21 can also be pulled out from between the mounting groove 18 and the multiple sets of limiting plates 20;

[0035] When the linkage rod 25 rotates, it drives the second bevel gear 24 at one end to rotate. The second bevel gear 24 drives the meshing first bevel gear 23 to rotate. The first bevel gear 23 drives the upper spiral conveyor rod 22 to rotate. The spiral conveyor rod 22 then transports the uncrushed defoaming masterbatch back to the dispersing box 2 for secondary processing.

[0036] It should be added that the striking component 27 is composed of a rubber ball block and a buffer spring. The filter plate 21 vibrates due to the elasticity of the buffer spring and the continuous contact between the rubber ball block and the filter plate 21.

[0037] It should be added that the multiple sets of striking components 27 have different lengths, and are set accordingly according to the slope of the filter plate 21.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
