Abstract
Description
Technical Field
[0001] This utility model relates to the field of crushing device technology, and in particular to a particle crushing device for processing rosin modified resin. Background Technology
[0002] In the processing of rosin-modified resins, particle crushing is one of the key pretreatment steps. Traditional crushing processes typically employ mechanical grinding or shearing, using high-speed rotating blades or grinding discs to physically pulverize resin particles. These devices usually include a feeding system, a crushing chamber, and a screening structure. Under mechanical force, the material is broken down into smaller particles to meet the particle size requirements of subsequent processing or applications.
[0003] A search revealed a utility model patent with authorization announcement number CN218423273U, which discloses a granulation crushing device for processing rosin modified resin. The device includes a processing box with a feed square tube at the top and a rotating door rotatably mounted on one side of the feed square tube. A pre-crushing roller is rotatably mounted at the bottom of the feed square tube inside the processing box. This granulation crushing device for processing rosin modified resin includes a pre-crushing roller, a pre-grinding block, and a first hydraulic cylinder. The pre-crushing roller performs preliminary crushing on the material entering the processing box through the feed square tube, and the height of the pre-grinding block can be adjusted by the first hydraulic cylinder, allowing for free adjustment of the pre-grinding degree and preventing large deviations in material size during subsequent crushing.
[0004] However, rosin-modified resin particles tend to accumulate at the arc-shaped angle between the pre-crushing roller and the processing box. Due to the stickiness of the rosin-modified resin particles, the upper rosin-modified resin particles are always in a feeding state, while some rosin-modified resin particles are blocked at the arc-shaped angle. At this time, they will adhere to the surface of the pre-crushing roller and the surface of the pre-grinding block like glue, forming a dense blockage layer, which affects the original crushing effect. In view of this, this application proposes a particle crushing device for rosin-modified resin processing based on the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a particle crushing device for processing rosin-modified resin.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A granular crushing device for processing rosin modified resin includes a crushing box, with a feed inlet at the top and a discharge outlet at the bottom. Inside the crushing box, a primary crushing component and a secondary crushing component are arranged from top to bottom.
[0008] The primary crushing assembly includes a first crushing roller rotatably mounted on a crushing box. A notch is provided on one side of the crushing box, and a crushing block is movably installed in the notch. A bracket is fixedly installed on one side of the crushing box, and a threaded rod is threadedly installed on the bracket. The threaded rod is rotatably connected to the crushing block. A rotating rod is fixedly installed at one end of the threaded rod. Two symmetrical guide rods are fixedly installed on one side of the crushing block, and one end of the guide rod passes through the bracket and is slidably connected to it.
[0009] A screen is provided below the discharge port, a feeding hopper is provided at the bottom of the screen, a feeding assembly is connected to the feeding hopper, and a feeding hopper is provided between the feeding assembly and the inlet.
[0010] Furthermore, the secondary crushing assembly includes two second crushing rollers rotatably mounted on the crushing box. Gears are fixedly mounted on the outside of each of the second crushing rollers, and the gears are meshed with each other. Synchronous pulleys are fixedly mounted on the first crushing roller and one of the second crushing rollers, and synchronous belts drive the synchronous pulleys together. A first motor is fixedly mounted on one end of the other second crushing roller.
[0011] Furthermore, a vibration motor is fixedly installed on the lower surface of the screen.
[0012] Furthermore, the feeding assembly includes a barrel, a second motor is fixedly installed at the top of the barrel, and a spiral blade is rotatably installed inside the barrel. The output end of the second motor is fixedly connected to the spiral blade.
[0013] Furthermore, a box cover is rotatably mounted on the top of the feed inlet via a hinge, and a fan is fixedly mounted on the box cover.
[0014] Furthermore, a guide plate is provided above the first crushing roller, and the guide plate is fixedly connected to the crushing box.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. This utility model, by setting up a primary crushing component and a crushing box, allows materials to be fed into the crushing box from the feed inlet. The materials are then squeezed between the first crushing roller and the crushing blocks to form pre-crushed particles. The pre-crushed particles slide down the inner wall of the crushing box onto the second crushing component, without remaining in the dead zone area between the first crushing roller and the crushing box. By rotating the rotating rod, the rotating rod drives the threaded rod to rotate, thereby driving the crushing blocks to move. This can change the size of the pre-crushed material, making it easier for the second crushing component to further refine and crush the pre-crushed particles.
[0017] 2. This utility model, by setting up a two-stage crushing component, a screen, and a vibrating motor, allows the pre-crushed particles to enter between the second crushing rollers. The first motor drives the two second crushing rollers to rotate in opposite directions, thereby further refining the pre-crushed particles. The refined particles fall through the screen to the discharge port. The vibrating motor on the screen can generate high-frequency vibration, making it less likely for the particles on the screen to clog, thus ensuring crushing efficiency.
[0018] 3. This utility model, by setting up a feeding assembly and a guide plate, allows qualified crushed particles to detach from the discharge port, while unqualified particles fall along the screen into the feeding hopper and enter the inside of the cylinder. At this time, the second motor is started, which drives the spiral blades to rotate and transport the unqualified particles at the bottom of the cylinder to the top of the cylinder. The particles then re-enter the crushing box through the feeding hopper for further crushing. The guide plate can prevent materials from falling into the crushing area that is not formed by the first crushing roller and the crushed blocks. Attached Figure Description

Two symmetrical guide rods 9 are fixedly installed on one side of the crushing block 5. One end of the guide rod 9 passes through the bracket 6 and is slidably connected to it.
[0028] Material is fed into crushing box 1 from feed inlet 2. It is squeezed between first crushing roller 4 and crushing block 5 to form pre-crushed particles. The pre-crushed particles slide down the inner wall of crushing box 1 onto the second crushing component. They will not remain in the dead zone area between first crushing roller 4 and crushing box 1. By rotating rotating rod 8, rotating rod 8 drives threaded rod 7 to rotate, thereby driving crushing block 5 to move. The size of pre-crushed material can be changed, which makes it easier for the second crushing component to further refine and crush the pre-crushed particles.
[0029] A screen 10 is provided below the discharge port 3, and a feeding hopper 11 is provided at the bottom of the screen 10. A feeding assembly is connected to the feeding hopper 11, and a feeding hopper 12 is provided between the feeding assembly and the inlet 2.

Gears 14 are fixedly mounted on the outside of each of the second crushing rollers 13, and the gears 14 are meshed with each other. Synchronous pulleys 15 are fixedly mounted on the first crushing roller 4 and one of the second crushing rollers 13, and synchronous belts 16 are connected between the synchronous pulleys 15. A first motor 17 is fixedly mounted on one end of the other second crushing roller 13.
[0031] When the pre-crushed particles enter between the second crushing rollers 13, the first motor 17 drives the two second crushing rollers 13 to rotate in opposite directions, thereby further refining the pre-crushed particles. The refined particles fall through the screen 10 to the discharge port 3.
[0032] Reference Figure 2 Specifically: A vibration motor 18 is fixedly installed on the lower surface of the screen 10. The vibration motor 18 on the screen 10 can generate high-frequency vibration, which makes it difficult for particles on the screen 10 to clog and ensures crushing efficiency.
[0033] Reference Figure 1 , Figure 5 Specifically: the feeding assembly includes a barrel 19, a second motor 20 is fixedly installed at the top of the barrel 19, a spiral blade 21 is rotatably installed inside the barrel 19, and the output end of the second motor 20 is fixedly connected to the spiral blade 21.
[0034] Qualified crushed particles are discharged from the discharge port 3, while unqualified particles fall along the screen 10 into the feeding hopper 11 and enter the inside of the barrel 19. At this time, the second motor 20 is started, and the second motor 20 drives the spiral blade 21 to rotate, which transports the unqualified particles at the bottom of the barrel 19 to the top of the barrel 19, and then re-enters the crushing box 1 through the feeding hopper 12 for further crushing.
[0035] Reference Figure 1-2 Specifically: The top of the feed inlet 2 is fitted with a cover 22 via a hinge, and a blower 23 is fixedly installed on the cover 22. After the entire crushing process is completed, the cover 22 is closed, and the blower 23 blows air into the crushing chamber 1 to blow away the remaining particles from the discharge port 3.
[0036] Reference Figure 2 Specifically: A guide plate 24 is provided above the first crushing roller 4. The guide plate 24 is fixedly connected to the crushing box 1. The guide plate 24 prevents materials from falling into the crushing area not formed by the first crushing roller 4 and the crushing block 5.
[0037] Working principle: Material is fed into crushing box 1 through feed inlet 2. It is squeezed between the first crushing roller 4 and crushing block 5 to form pre-crushed particles. The pre-crushed particles slide down the inner wall of crushing box 1 onto the second crushing component. They will not remain in the dead zone area between the first crushing roller 4 and crushing box 1. By rotating the rotating rod 8, the rotating rod 8 drives the threaded rod 7 to rotate, thereby driving the crushing block 5 to move. The size of the pre-crushed material can be changed, which makes it easier for the second crushing component to further refine the pre-crushed particles.
[0038] When the pre-crushed particles enter between the second crushing rollers 13, the first motor 17 drives the two second crushing rollers 13 to rotate in opposite directions, thereby further refining the pre-crushed particles. The refined particles fall through the screen 10 to the discharge port 3. The vibrating motor 18 on the screen 10 can generate high-frequency vibration, making it less likely for the particles on the screen 10 to clog, thus ensuring crushing efficiency.
[0039] Qualified crushed particles are discharged from the discharge port 3, while unqualified particles fall along the screen 10 into the feeding hopper 11 and enter the inside of the barrel 19. At this time, the second motor 20 is started. The second motor 20 drives the spiral blade 21 to rotate and transport the unqualified particles at the bottom of the barrel 19 to the top of the barrel 19. The particles are then fed back into the crushing box 1 through the feeding hopper 12 for further crushing. The guide plate 24 can prevent the material from falling into the crushing area that is not formed by the first crushing roller 4 and the crushing block 5.
[0040] After the entire crushing process is completed, close the box cover 22, and blow air into the crushing box 1 with the blower 23 to blow away the remaining particles from the discharge port 3.
