Description

Technical Field

[0001] The utility model relates to the technical field of roller presses, in particular to a roller press buffer structure. Background Art

[0002] Roller press, also known as extrusion mill, roller mill, and double-roller press. In the production process system of roller press, the roller gap of the roller press is often skewed due to the segregation of materials in the buffer bin above the roller press. In order to make the material discharge uniform, a roller press buffer structure is required.

[0003] According to the description of a roller press steady flow bin buffer plate disclosed in the patent website (authorization announcement number: CN 218250435U), "The utility model discloses a roller press steady flow bin buffer plate, which belongs to the technical field of roller press steady flow bins. The key points of its technical solution include sliding rods, four of which are arranged, and the outer walls of the four sliding rods are slidably connected with buffer plates. The four ends of the outer walls of the buffer plates are fixedly connected with inclined material guide plates, and a bottom plate located below the buffer plate is fixedly connected between the four sliding rods. The material falls to the upper end of the bottom buffer seat. The buffer seat has a truncated cone structure as a whole, and secondary buffering is performed through slopes with equal slopes on all sides. The material slides at the periphery of the buffer seat, so that the material can be evenly distributed and guided. The buffer spring contracts after being subjected to impact force, and buffers and absorbs the impact force, effectively reduces the impact, and has a good buffering effect. It solves the problem that the existing roller press steady flow bin buffer plate has a simple structure, poor buffering effect, uneven material during buffering, and affects the stable operation of the production system."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model guides the material between the gradually shrinking inner walls of the guide hopper for initial buffering, and performs secondary buffering through the slopes with equal slopes on all sides. The material flows downward through the guide plates in all directions. It is easy to use and the material is guided evenly. However, in actual use, the inner wall of the guide hopper gradually shrinks. When unloading, the material is easily blocked inside the guide hopper, resulting in low work efficiency. Secondly, the height required for unloading the material varies depending on the usage scenario. The guide plate of the device has a fixed slope, which is not convenient to use when unloading at different heights. Therefore, it is necessary to improve a roller press buffer structure to solve the above problems. Utility Model Content

[0028] Embodiment 1:

[0029] See also Figure 1-5The utility model provides a technical solution: a roller press buffer structure, including four slide bars 1 and a buffer plate 2, the tops of the four slide bars 1 are fixedly installed with a mounting plate 3, the tops of the buffer plates 2 are fixedly installed with four guide blocks 4, the outsides of the four slide bars 1 are fixedly installed with a fixing frame 5, the inside of the fixing frame 5 is provided with a buffer funnel 6, the top of the buffer plate 2 is fixedly installed with a buffer seat 7, the outside of the buffer plate 2 is provided with a loading and unloading mechanism 8, and the outside of the slide bar 1 is provided with a buffer mechanism 9.

[0032] Furthermore, the reciprocating block 814 is clamped on the outside of the gear 816 , and the knocking rod 813 contacts the outside of the buffer funnel 6 to knock the buffer funnel 6 back and forth.

[0033] Furthermore, the adjustment and unloading assembly 82 includes eight protrusions B821, and the eight protrusions B821 are respectively fixedly installed on the outside of the buffer plate 2, and the back of the buffer plate 2 and the inside of the left protrusion B821 are both rotatably installed with a rotating shaft A822, and both ends of the two rotating shafts A822 are fixedly installed with a bevel gear A823, and the front of the buffer plate 2 and the inside of the right protrusion B821 are both rotatably installed with a rotating shaft B824, and the ends of the two rotating shafts B824 close to the bevel gear A823 are fixedly installed with a bevel gear B825, and the end of the right rotating shaft B824 away from the bevel gear B825 is fixedly installed with a worm gear 826, and an L-shaped mounting block 827 is fixedly installed on the right side of the buffer plate 2, and a worm 828 is rotatably installed inside the L-shaped mounting block 827, and guide plates 829 are fixedly installed on the outside of the two rotating shafts A822 and the two rotating shafts B824, and the four guide plates 829 can be synchronously adjusted in angle.

[0035] Embodiment two:

[0036] See also Figure 6 , and combined with Example 1, it is further obtained that the buffer mechanism 9 includes four sliding sleeves 91, the four sliding sleeves 91 are fixedly installed inside the buffer plate 2, the outside of the four slide bars 1 is fixedly installed with a fixed plate 92, the bottom of the buffer plate 2 is fixedly installed with four protrusions C93, the inside of the four protrusions C93 are rotatably installed with a rotating rod 94, the inside of the fixed plate 92 is slidably installed with four sliders 95, and the outside of the four sliders 95 is fixedly installed with springs 96 to buffer and absorb the impact force of the fall.

[0037] Furthermore, one end of the spring 96 away from the slider 95 is fixedly installed on the fixed plate 92, the four sliding sleeves 91 are respectively slidably installed on the outside of the four sliding rods 1, and the four rotating rods 94 are respectively rotatably installed on the inside of the four sliders 95, so that the distance between the buffer plate 2 and the fixed plate 92 changes, driving the spring 96 to compress.

[0038] In actual operation, when this device is used, the worm 828 is rotated to mesh with the worm wheel 826, so that the rotating shaft B824 rotates and drives the bevel gear B825 to rotate. The bevel gear B825 meshes with the bevel gear A823, driving the back rotating shaft A822 to rotate, so that the bevel gear A823 rotates and meshes with the bevel gear A823 on the other rotating shaft A822, so that the two rotating shafts A822 rotate at the same time, and the bevel gear A823 meshes with another bevel gear B825, so that the two rotating shafts A822 and the two rotating shafts B824 rotate synchronously, so that the four guide plates 829 can be adjusted synchronously in angle. When the material falls from a high altitude, it first enters the interior of the buffer funnel 6, and the material is guided between the gradually shrinking inner walls of the buffer funnel 6 for preliminary slowing down. The starting motor 815 drives the gear 816 to rotate, and the reciprocating block 814 is clamped in the interior of the gear 816, and reciprocates with the rotation of the gear 816. Column 812 drives knocking rod 813 to knock buffer funnel 6 back and forth, causing buffer funnel 6 to shake slightly, making the material smoother when guided to fall, avoiding the inner wall of buffer funnel 6 from gradually shrinking. When unloading, the material is easily blocked inside buffer funnel 6, resulting in low work efficiency. The material then falls to the top of buffer seat 7, and the material is slowed down for a second time by the slopes around it. The material slides on the edge of buffer seat 7, making the material evenly distributed, and finally slides to the top of buffer plate 2, and then flows to the bottom through four adjustable guide plates 829. When the material falls to the top of buffer seat 7, the impact force of the falling material drives the sliding sleeve 91 to slide on the outside of sliding rod 1, so that the distance between buffer plate 2 and fixed plate 92 changes, so that the rotating rod 94 rotates between protrusion C93 and slider 95, driving slider 95 to slide inside fixed plate 92, causing compression on spring 96, and spring 96 buffers and absorbs the falling impact force.

[0039] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
