Description

Technical Field

[0001] This utility model relates to the field of feed production machinery technology, and in particular to a device for adjusting the gap between the die rollers of an anti-clogging die ring pellet mill. Background Technology

[0002] Ring die pellet mill (also known as ring die pellet feed machine or ring die pellet feed forming machine) is a type of feed pelleting equipment. It is a feed processing machine that directly presses crushed materials such as corn, soybean meal, straw, grass, and rice husks into pellets. During the operation of a ring die pellet mill, the optimal working gap between the pressure roller and the ring die is maintained within the range of 0 to 0.1 mm. This gap is maintained by the pressure roller adjustment mechanism. However, existing roller gap adjustment mechanisms suffer from inconvenience, inaccurate adjustment distances, and are prone to causing die blockage, unstable pellet quality, and reduced efficiency. When the ring die pellet mill becomes clogged, a hard and dense material layer forms between the ring die and the pressure roller. This material layer hardens very quickly, requiring a long time for manual cleaning, interrupting continuous production and significantly impacting output. This can result in the loss of thousands of tons of product annually. Therefore, a die roller gap adjustment device for anti-clogging ring die pellet mills is designed to solve these problems. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose a device for adjusting the gap between the mold rollers of an anti-clogging mold ring granulator.

[0004] The technical problem to be solved by this utility model is to provide a device for adjusting the gap between the die rollers of an anti-clogging ring die pellet mill, so as to solve the problem of inconvenient adjustment of the gap between the die rollers of the existing ring die pellet mill.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An anti-clogging die ring pellet mill die roller gap adjustment device includes an extrusion die ring and a mounting bracket, wherein the mounting bracket is installed on the inner side of the extrusion die ring; The mounting bracket includes a top plate, a support column, a bottom plate, a sliding groove, and a slider. The support column is fixedly installed in the center of the top plate, and the bottom plate is fixedly installed at the bottom of the support column. Sliding grooves are opened on the left and right sides of the upper surface of the top plate and the bottom plate. Sliding sliders are slidably installed in the sliding grooves. Mold rollers are rotatably installed between the sliders on the left and right sides of the top plate and the bottom plate through bearings. An adjustment component for adjusting the gap between the two mold rollers is installed on the top plate.

[0006] Preferably, the adjusting assembly includes a guide rod, a guide sleeve, a hydraulic rod, a lifting block, and a connecting rod. Guide rods are fixedly mounted on both sliders on the top plate. Guide sleeves are fixedly mounted on both the left and right sides of the upper surface of the top plate. A hydraulic rod is installed in the center of the upper surface of the top plate. A lifting block is fixedly mounted on the output end of the hydraulic rod. Connecting rods are rotatably mounted on both the left and right sides of the lifting block. The other end of the connecting rod is rotatably mounted on the guide rod, facilitating the lifting of the lifting block by raising and lowering the hydraulic rod. The connecting rod pulls the two guide rods to move, thereby causing the two sliders to slide, thus adjusting the distance between the two die rollers and, consequently, adjusting the gap between the die rollers and the extrusion die ring.

[0007] Preferably, the two sliders on the top plate are at a horizontal height higher than the upper surface of the top plate, and the guide rod is fixedly installed on the side surface of the slider facing the center of the top plate, which facilitates the connection between the guide rod and the slider.

[0008] Preferably, the diameter of the central through hole of the guide sleeve is equal to the diameter of the guide rod, and the guide rod passes through the guide sleeve, so that the guide sleeve can guide the guide rod.

[0009] Preferably, the two guide rods are of the same length, which facilitates the connection between the two guide rods and the connecting rod, and also ensures that the connecting rod drives the guide rods to move the same distance.

[0010] Preferably, the two connecting rods are in an inverted V-shape and have the same length, which facilitates the simultaneous movement of the two guide rods by the two connecting rods.

[0011] Preferably, when the hydraulic rod extends to its maximum length, the two sliders on the top plate slide to the side of the slide groove near the center of the upper surface of the top plate. When the hydraulic rod extends to its minimum length, the two sliders on the top plate slide to the side of the slide groove away from the center of the upper surface of the top plate. This prevents the sliders from squeezing the slide groove during the extension and retraction of the hydraulic rod, thus preventing damage to the hydraulic rod and ensuring its service life.

[0012] Preferably, when the hydraulic rod is extended to its minimum length, the outer surface of the die roller is attached to the inner surface of the extrusion die ring to prevent the die roller from squeezing the extrusion die ring and causing damage to the extrusion die ring.

[0013] Preferably, multiple guide rods are fixedly installed on the upper surface of the top plate, and the guide rods pass through the lifting block to ensure the stability of the lifting block driven by the hydraulic rod.

[0014] Preferably, the guide rod is engraved with millimeter scales, which facilitates determining the distance the guide rod drives the slider to slide along the groove, thereby achieving the effect of determining the distance between the die roller and the extrusion die ring.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above solution, by setting an adjustment component, when it is necessary to adjust the distance between the two mold rollers, the hydraulic rod extends and retracts to drive the lifting block to move up and down. The up and down movement of the lifting block drives the guide rod to move along the guide sleeve through the connecting rod. The guide rod drives the slider on the top plate to move along the slide groove, thereby achieving the effect of adjusting the distance between the two mold rollers and thus the effect of adjusting the gap between the two mold rollers and the extrusion die ring. The operation is simple and convenient. Moreover, when adjusting the distance between the mold rollers, the slider below the mold rollers can move left and right along the slide groove on the bottom plate to ensure the vertical state of the mold rollers.

[0017] In the above scheme, by setting millimeter scales, when the hydraulic rod extends and retracts to move the guide rod to adjust the distance between the two die rollers, the millimeter scales on the guide rod are positioned on the guide sleeve to determine the sliding distance of the slider along the groove, thereby determining the gap between the die roller and the extrusion die ring. This ensures the accuracy of the gap between the die roller and the extrusion die ring after the die roller is adjusted, and prevents the extrusion die ring from clogging.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present invention provides a die roller gap adjustment device for an anti-clogging die ring pellet mill, including an extrusion die ring 1 and a mounting bracket, wherein the mounting bracket is installed on the inner side of the extrusion die ring 1; The mounting bracket includes a top plate 2, a support column 4, a bottom plate 5, a slide groove 6, and a slider 7. The support column 4 is fixedly installed in the center of the top plate 2, and the bottom plate 5 is fixedly installed at the bottom of the support column 4. Slide grooves 6 are opened on the left and right sides of the upper surface of the top plate 2 and the bottom plate 5. The slider 7 is slidably installed in the slide groove 6. The mold rollers 3 are rotatably installed between the sliders 7 on the left and right sides of the top plate 2 and the bottom plate 5 through bearings. An adjustment component for adjusting the gap between the two mold rollers 3 is installed on the top plate 2.

[0025] In this embodiment, the adjustment assembly includes a guide rod 8, a guide sleeve 9, a hydraulic rod 10, a lifting block 11, and a connecting rod 12. Guide rods 8 are fixedly installed on both sliders 7 on the top plate 2. Guide sleeves 9 are fixedly installed on both the left and right sides of the upper surface of the top plate 2. A hydraulic rod 10 is installed in the center of the upper surface of the top plate 2. A lifting block 11 is fixedly installed at the output end of the hydraulic rod 10. Connecting rods 12 are rotatably installed on both the left and right sides of the lifting block 11. The other end of the connecting rod 12 is rotatably installed on the guide rod 8, so that the lifting block 11 can be lifted and lowered by the lifting of the hydraulic rod 10. The connecting rod 12 pulls the two guide rods 8 to move, thereby driving the two sliders 7 to slide, thereby achieving the effect of adjusting the distance between the two mold rollers 3, and thus achieving the effect of adjusting the gap between the mold roller 3 and the extrusion mold ring 1.

[0026] In this embodiment, the two sliders 7 on the top plate 2 are at a horizontal height higher than the upper surface of the top plate 2, and the guide rod 8 is fixedly installed on the side surface of the slider 7 facing the center of the top plate 2, which facilitates the connection between the guide rod 8 and the slider 7.

[0027] In this embodiment, the diameter of the central through hole of the guide sleeve 9 is equal to the diameter of the guide rod 8, and the guide rod 8 passes through the guide sleeve 9, which facilitates the guide sleeve 9 to guide the guide rod 8.

[0028] In this embodiment, the two guide rods 8 are of the same length, which facilitates the connection between the two guide rods 8 and the connecting rod 12, and also facilitates the connecting rod 12 to drive the guide rods 8 to move the same distance.

[0029] In this embodiment, the two connecting rods 12 are in the shape of an inverted V and the two connecting rods 12 are of the same length, which makes it convenient for the two connecting rods 12 to drive the two guide rods 8 to move simultaneously.

[0030] In this embodiment, when the hydraulic rod 10 extends to its maximum length, the two sliders 7 on the top plate 2 slide to the side of the slide groove 6 near the center of the upper surface of the top plate 2. When the hydraulic rod 10 extends to its minimum length, the two sliders 7 on the top plate 2 slide to the side of the slide groove 6 away from the center of the upper surface of the top plate 2. This prevents the sliders 7 from squeezing the slide groove 6 during the extension and retraction of the hydraulic rod 10, which would otherwise damage the hydraulic rod 10 and ensure the service life of the hydraulic rod 10.

[0031] In this embodiment, when the hydraulic rod 10 extends to its minimum length, the outer surface of the die roller 3 is attached to the inner surface of the extrusion die ring 1 to prevent the die roller 3 from squeezing the extrusion die ring 1 and causing damage to the extrusion die ring 1.

[0032] In this embodiment, multiple guide rods are fixedly installed on the upper surface of the top plate 2, and the guide rods pass through the lifting block 11 to ensure the stability of the lifting block 11 driven by the hydraulic rod 10.

[0033] By incorporating an adjustment mechanism, when the distance between the two die rollers 3 needs to be adjusted, the hydraulic rod 10 extends and retracts, causing the lifting block 11 to move up and down. The up and down movement of the lifting block 11 drives the guide rod 8 to move along the guide sleeve 9 via the connecting rod 12. The guide rod 8 then drives the slider 7 on the top plate 2 to move along the slide groove 6, thereby adjusting the distance between the two die rollers 3 and the gap between the two die rollers 3 and the extrusion die ring 1. The operation is simple and convenient. Furthermore, when adjusting the distance between the die rollers 3, the slider 7 below the die rollers 3 can move left and right along the slide groove 6 on the bottom plate 5 to ensure the vertical state of the die rollers 3.

[0034] Reference Figure 5 As shown in this embodiment, the guide rod 8 is engraved with millimeter scale 801, which makes it convenient to determine the distance that the guide rod 8 drives the slider 7 to slide along the slide groove 6 through the millimeter scale on the guide rod 8, thereby achieving the effect of determining the distance between the die roller 3 and the extrusion die ring 1.

[0035] By setting a millimeter scale 801, when the hydraulic rod 10 extends and retracts to move the guide rod 8 to adjust the distance between the two die rollers 3, the millimeter scale 801 on the guide rod 8 is positioned on the guide sleeve 9 to determine the sliding distance of the slider 7 along the slide groove 6, thereby determining the gap between the die roller 3 and the extrusion die ring 1. This ensures the accuracy of the gap between the die roller 3 and the extrusion die ring 1 after the die roller 3 is adjusted, and prevents the extrusion die ring 1 from clogging.
