Abstract
Description
Technical Field
[0001] The utility model relates to the field of granulation production equipment, in particular to a fully enclosed unloading system of a granulation production line. Background Art
[0002] Granulator is a kind of molding machine that can make materials into specific shapes. It is widely used in chemical, petrochemical, pharmaceutical, food, building materials, mining and metallurgy, environmental protection, printing and dyeing, ceramics, rubber, plastics and other fields.
[0003] In order to prevent external impurities from contaminating the granular materials and to prevent dust from being raised during unloading to pollute the surrounding environment, the unloading device of the granulation production line in the prior art is generally operated under closed conditions, and the discharged particles are generally collected through bags, barrels or conveyor belts during unloading. In particular, for collection in barrels, there is often a situation where the space utilization rate of the collecting barrel is not high. The unloaded materials are often continuously discharged in one direction, so the materials will accumulate. The accumulation is generally in the shape of an inverted cone, and there is often space outside the cone. As a result, the final space of the collecting barrel cannot be fully utilized, and human intervention is often required, which is less practical.
[0004] Therefore, it is necessary to propose a fully enclosed unloading system for a granulation production line to solve the above problems. Utility Model Content
[0005] The main purpose of the utility model is to provide a fully enclosed unloading system for a granulation production line, which can effectively solve the problems in the background technology.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A fully enclosed unloading system of a granulation production line, comprising a unloading device body, a closed cover arranged at the lower end of the unloading device body, a cover door hinged to one side of the closed cover, and a collecting bucket placed in the closed cover and corresponding to the bottom end of the unloading device body, wherein a material sparging mechanism is arranged in the closed cover, and the material sparging mechanism comprises a truncated cone-shaped material distributing platform arranged below the unloading device body and a driving mechanism for driving the longitudinal displacement of the material distributing platform;
[0008] The driving mechanism includes a second horizontal axis arranged on the inner side of the closed cover and directly below the material distribution platform, an incomplete gear is arranged at the end of the second horizontal axis, and second racks corresponding to the incomplete gear are symmetrically arranged on the front and rear sides of the incomplete gear, and connecting plates are fixedly arranged at the bottom and top of the two second racks at the same end, a fixing rod is arranged on the side wall of the lower end of the material distribution platform, and the end of the fixing rod away from the material distribution platform is fixedly connected to the side wall of the whole composed of the second rack and the connecting plate, and a motor for driving the second horizontal axis to rotate is arranged on one side of the closed cover.
[0009] Preferably, a through hole for dropping materials is provided through the top of the material distribution table.
[0010] Preferably, a guide bar is provided on the side of the second rack away from the incomplete gear, a fixing frame corresponding to the second rack is provided on the inner wall of the closing cover, a guide groove adapted to the guide bar is provided on the side of the fixing frame facing the second rack, and the guide bar and the guide groove are slidably guided.
[0011] Preferably, it also includes an anti-blocking mechanism, which includes a first horizontal axis rotatably connected to the lower end of the discharge device body, stirring blades are evenly arranged on the part of the first horizontal axis located on the inner side of the lower end of the discharge device body, a gear is arranged at the end of the first horizontal axis, and a first rack meshing with the gear is arranged on the top of the connecting plate located at the upper end of the second rack.
[0012] Compared with the prior art, the utility model provides a fully enclosed unloading system for a granulation production line, which has the following beneficial effects:
[0013] 1. The fully enclosed unloading system of the granulation production line is composed of a material distribution platform and a driving mechanism for driving the longitudinal displacement of the material distribution platform through the material leveling mechanism. Since the material distribution platform is in the shape of a truncated cone, the falling materials will be evenly scattered downward along the outside of the material distribution platform and fall in a parabola. Therefore, when the height of the material distribution platform changes, the falling materials will be distributed in different areas of the collecting bucket. When the material distribution platform is higher, the materials falling into the collecting bucket will be farther away from the axis of the collecting bucket. When the material distribution platform is lower, the materials falling into the collecting bucket will be closer to the axis of the collecting bucket. The materials falling through the through hole will fall to the middle of the collecting bucket, thereby improving the space utilization of the collecting bucket and increasing practicality. In addition, the setting of the support platform, bottom cylinder and spring can automatically descend when the material in the collecting bucket increases, thereby ensuring that the landing point of the falling materials is at the same height.
[0014] 2. The fully enclosed unloading system of the granulation production line is linked with the driving mechanism through the anti-blocking mechanism, which facilitates the continuous stirring of the lower end of the unloading device body during unloading, avoiding the material blocking the lower end discharge port of the unloading device body.

[0025] In addition, it also includes an anti-blocking mechanism, which includes a first transverse axis 10 rotatably connected to the lower end of the discharge device body 1, and stirring blades 11 are evenly arranged on the part of the first transverse axis 10 located on the inner side of the lower end of the discharge device body 1, and a gear 12 is arranged at the end of the first transverse axis 10, and a first rack 13 meshing with the gear 12 is arranged on the top of the connecting plate 17 located at the upper end of the second rack 18.
