Technical Field
[0001] This utility model relates to the field of crushing devices, and in particular to a particle crushing and segmenting device. Background Technology
[0002] In food processing, there are devices that break down and separate particles into smaller pieces. These devices use two opposing rotating crushing rollers to crush and separate the particles. This structure is suitable for situations where the initial particle size is similar, but the crushing effect is not good when the particle size varies greatly. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a particle crushing and segmentation device, which facilitates the screening of particles of different sizes before separate crushing, resulting in a good crushing effect.
[0004] The technical solution of this utility model is as follows:
[0005] A pellet crushing and segmenting device includes a casing, a feeding section, and a crushing section;
[0006] The crushing section includes a pair of first extrusion rollers, a pair of second extrusion rollers, and a drive mechanism. The first extrusion rollers and the second extrusion rollers are rotatably disposed on the top sides of the machine housing. The drive mechanism drives the paired first extrusion rollers and the second extrusion rollers to move in opposite directions. The gap between the first extrusion rollers is larger than the gap between the second extrusion rollers.
[0007] The feeding section includes a feeding hopper, a first screen, a second screen, a first channel, and a second channel. The feeding hopper is located at the top center of the machine housing and communicates with the interior of the machine housing. The first screen and the second screen are respectively inclinedly arranged on the top and bottom sides of the feeding hopper. The mesh size of the first screen is larger than that of the second screen, and the lower end of the first screen is close to the higher end of the second screen. The feeding hopper has a first discharge port corresponding to the lower end of the first screen and a second discharge port corresponding to the lower end of the second screen. One end of the first channel is connected to the first discharge port, and the other end is connected to the inner side of the machine housing, aligning between the first extrusion rollers. One end of the second channel is connected to the second discharge port, and the other end is connected to the inner side of the machine housing, aligning between the second extrusion rollers. The bottom inner side of the machine housing has two partitions that divide the bottom inner side of the machine housing into three collection chambers, which are respectively aligned with the bottom of the first extrusion roller, the bottom of the feeding hopper, and the bottom of the second extrusion roller.
[0008] In a further technical solution, the driving mechanism includes a motor, a first gear, a second gear, a first pulley, a second pulley, and a transmission belt. The ends of the first and second extrusion rollers extend to the outside of the housing. The first gears are respectively located at the ends of the two first extrusion rollers and mesh with each other. The second gears are respectively located at the ends of the two second extrusion rollers and mesh with each other. The first pulley is located at the end of one of the first extrusion rollers, and the second pulley is located at the end of one of the second extrusion rollers. The transmission belt is located outside the first pulley and the second pulley. The motor drives the end of the first extrusion roller where the first pulley is located.
[0009] In a further technical solution, both the first channel and the second channel are flat.
[0010] In a further technical solution, the width of the end of the first channel near the first extrusion roller gradually decreases along the direction of approaching the first extrusion roller, and the width of the end of the second channel near the second extrusion roller gradually decreases along the direction of approaching the second extrusion roller.
[0011] In a further technical solution, the two sides of the feed hopper are respectively provided with support blocks that can be detachably connected to the first screen and the second screen.
[0012] In a further technical solution, the collection chamber is provided with collection slots, and the front side of the housing is provided with an opening for the collection slots to enter and exit.
[0013] In a further technical solution, a handle is provided on the front side of the collection trough.
[0014] The beneficial effects of this utility model are:
[0015] 1. After the particles enter from the feed hopper, the smaller particles pass through the first screen and roll obliquely into the first channel. From the first channel, they are guided to the space between the first extrusion rollers. The first extrusion rollers rotate in opposite directions to crush and break the particles into fragments, which then fall into the corresponding collection chamber at the bottom of the machine casing. Similarly, the second screen passes through even smaller particles or impurities, which directly enter another collection chamber from the bottom of the feed hopper. The particles on the second screen roll obliquely into the second channel, where the second extrusion rollers rotate in opposite directions to crush and break the particles into fragments, which then fall into the last collection chamber at the bottom of the machine casing. This device can separate the particles during feeding and separate impurities and particles that do not meet production standards. The screened particles can then enter the first and second extrusion rollers with different gaps for crushing and fragmenting, ensuring the crushing effect.
[0016] 2. The first and second extrusion rollers can be driven simultaneously by a single motor, resulting in high efficiency;
[0017] 3. The flat first and second channels facilitate the uniform discharge of material between the first and second extrusion rollers. Attached Figure Description

[0023] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0024] Example:
[0025] like Figures 1-3As shown, a pellet crushing and splitting device includes a housing 10, a feeding section, and a crushing section. The crushing section includes a pair of horizontally arranged and parallel first extrusion rollers 21, a pair of horizontally arranged and parallel second extrusion rollers 22, and a drive mechanism. The first extrusion rollers 21 and the second extrusion rollers 22 are respectively rotatably disposed on both sides of the top of the housing 10. The drive mechanism includes a motor 31, a first gear 32, a second gear 33, a first pulley 34, a second pulley 35, and a transmission belt 36. The two ends of the first extrusion rollers 21 and the two ends of the second extrusion rollers 22 are respectively disposed on the front and rear sides of the housing 10. The rear end of the 2 extends through the housing 10 to the outside of the housing 10. The first gear 32 is located at the rear end of each of the two first extrusion rollers 21 and meshes with each other. The second gear 33 is located at the rear end of each of the two second extrusion rollers 22 and meshes with each other. The first pulley 34 is located at the end of one of the first extrusion rollers 21, and the second pulley 35 is located at the end of one of the second extrusion rollers 22. The transmission belt 36 is located outside the first pulley 34 and the second pulley 35. The motor 31 drives the rear end of the first extrusion roller 21 connected to the first pulley 34. The gap between the first extrusion rollers 21 is greater than the gap between the second extrusion rollers 22. The housing 10... A first through hole 11 is provided in the middle of the top of the housing 10. A second through hole 12 corresponding to the space between the first extrusion rollers 21 and a third through hole 13 corresponding to the space between the second extrusion rollers 22 are provided on both sides of the first through hole 11. The feeding section includes a feeding hopper 40, a first screen 41, a second screen 42, a first channel 43, and a second channel 44. The feeding hopper 40 is located in the middle of the top of the housing 10, and its bottom passes through the first through hole 11. The first screen 41 and the second screen 42 are respectively inclinedly arranged on the top and bottom sides of the feeding hopper 40. The mesh size of the first screen 41 is larger than that of the second screen 42, and the lower end of the first screen 41 is closer to... The higher end of the second screen 42; the feed hopper 40 is provided with a first discharge port 45 corresponding to the lower end of the first screen 41, and a second discharge port 46 corresponding to the lower end of the second screen 42; one end of the first channel 43 is connected to the first discharge port 45, and the other end is inserted into the second through hole 12; one end of the second channel 44 is connected to the second discharge port 46, and the other end is inserted into the third through hole 13; two partitions 14 are provided on the inner bottom of the housing 10, which divide the inner bottom of the housing 10 into three collection chambers, and the three collection chambers are respectively aligned with the bottom of the first extrusion roller 21, the bottom of the feed hopper 40 and the bottom of the second extrusion roller 22.
[0026] The working principle of the above technical solution is as follows:
[0027] After the particles enter from the feed hopper 40, smaller particles pass through the first screen 41, and the particles on the first screen 41 roll obliquely to the first channel 43. From the first channel 43, they are guided to the space between the first extrusion rollers 21. The first extrusion rollers 21 rotate in opposite directions, crushing and breaking the particles into fragments, which then fall into the corresponding collection chamber at the bottom of the casing 10. Similarly, even smaller particles or impurities pass through the second screen 42, directly entering another collection chamber from the bottom of the feed hopper 40. The particles on the second screen 42 roll obliquely to the second channel 44, where the second extrusion rollers 22 rotate in opposite directions, crushing and breaking the particles into fragments, which then fall into the casing. The last collection chamber at the bottom of the 10th is used for collection; this device can screen the particles during feeding and separate impurities and particles that do not meet production standards. The screened particles can enter between the first extrusion roller 21 and the second extrusion roller 22 with different gaps. The motor 31 drives the first pulley 34 and the first gear 32 to rotate, which makes the first extrusion roller 21 rotate in opposite directions. The second pulley 35 is driven to rotate through the transmission belt 36, which in turn drives the second gear 33 to rotate, making the second extrusion roller 22 rotate in opposite directions, thus crushing and separating the incoming particles to ensure the crushing effect.
[0028] In another embodiment, such as Figure 1-2 As shown, both the first channel 43 and the second channel 44 are flat; the width of the first channel 43 near the first extrusion roller 21 gradually decreases along the direction of the first extrusion roller 21, and the width of the second channel 44 near the second extrusion roller 22 gradually decreases along the direction of the second extrusion roller 22.
[0029] The flat first channel 43 and the second channel 44 facilitate the uniform discharge of material between the first extrusion roller 21 and the second extrusion roller 22, respectively. The above arrangement allows the end of the first channel 43 to be closer to the gap between the first extrusion rollers 21, preventing particles from falling outside the first extrusion roller 21 during discharge. Similarly, the end of the second channel 44 can prevent particles from falling outside the second extrusion roller 22 during discharge.
[0030] In another embodiment, such as Figure 1 As shown, the feed hopper 40 has support blocks 47 on both sides that can be detachably connected to the first screen 41 and the second screen 42, and the overlapping method can be selected.
[0031] This facilitates the replacement of the first screen 41 and the second screen 42.
[0032] In another embodiment, such as Figure 1 and Figure 3 As shown, the collection chamber is provided with collection slots 15, and the front side of the housing 10 is provided with an opening for the collection slots 15 to enter and exit; the front side of the collection slots 15 is provided with a handle 16.
[0033] Pulling handle 16 makes it easy to remove the corresponding collection slot 15.
[0034] The above-described embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
