Abstract
Description
Technical Field
[0001] The present application relates to the technical field of blanking structures, and specifically discloses an anti-blocking blanking structure. Background Art
[0002] In most manufacturing processes, a variety of raw materials are usually used, and the production is carried out through different proportions of the raw materials. The raw materials are usually fed into a hopper with a feeding mechanism.
[0003] The present invention is directed to a hopper for containing and feeding powdered raw materials and its associated discharge structure. In the prior art, all powdered raw materials of the same batch are usually placed into the hopper, and the raw materials of the batch are fed into the subsequent process equipment through the discharge structure. However, powdered raw materials are prone to blockage during free discharge and transportation. In particular, for a discharge structure that needs to extend into a subsequent process equipment and has a raw material conveying pipeline, powdered raw materials are prone to blockage during the discharge process in the conveying pipeline. Therefore, a spiral conveying mechanism is usually installed in the discharge structure in the prior art. However, the spiral conveying mechanism discharges raw materials from the chamber between adjacent spiral conveying blades through the continuous rotation of the spiral conveying blades around the axis, which can easily cause agglomeration of the powdered raw materials and affect the subsequent processing technology.
[0004] Therefore, in view of this, the inventor provides an anti-blocking material discharge structure to solve the above problems. Utility Model Content
[0005] The purpose of the utility model is to solve the problem that the spiral conveying mechanism installed in the traditional material feeding structure easily causes the raw materials to agglomerate between adjacent spiral conveying blades during the raw material conveying process, thereby affecting the subsequent processing technology.
[0006] In order to achieve the above-mentioned purpose, the basic scheme of the present invention provides an anti-blocking material discharge structure, including a conveying pipe arranged below the hopper and connected to the hopper, an anti-blocking structure arranged in the conveying pipe, and a driving structure arranged on the hopper and used to drive the anti-blocking structure. The anti-blocking structure includes a secondary shaft coaxially arranged in the conveying pipe and driven by the driving structure, a plurality of guide plates circumferentially and vertically slidably connected to the outside of the secondary shaft, a plurality of pusher inclined plates respectively fixed on the guide plates and used to push the powdered raw materials downward, and a base fixed on one side of the bottom end of the conveying pipe and used to lift the guide plates back and forth in sequence.
[0007] Furthermore, the secondary shaft is also fixedly connected with a resetter for pressing the guide plate downwards.
[0008] Furthermore, the resetter includes a reset sleeve fixed on the secondary shaft and into which the top end of the guide plate extends, a plurality of reset guide plates circumferentially fixed in the reset sleeve and aligned with the guide plates respectively, and a plurality of flat springs respectively sleeved on the outside of the reset guide plates and against the top end of the guide plates.
[0009] Furthermore, the pusher inclined plates are all inclined toward the same side, and the bottom ends of the pusher inclined plates are fixedly connected with vertical pusher vertical plates.
[0010] Furthermore, the base includes a bottom support and a connecting rod for connecting the bottom support and the bottom end of the conveying pipe. The bottom support is provided with a receiving groove for the guide plate and the secondary shaft to extend into. The bottom end of the guide plate is provided with an arc-shaped follower block, and the bottom surface of the receiving groove is provided with an arc-shaped groove for the follower block to slide into.
[0011] Furthermore, a plurality of arc-shaped grooves are provided in the accommodating groove, which are symmetrical about the axis of the accommodating groove, and the end surfaces of the accommodating groove between adjacent arc-shaped grooves are planes.
[0012] Furthermore, the pusher inclined plates on the plurality of guide plates outside the secondary shaft are staggeredly distributed.
[0013] The principle and effect of this solution are:
[0014] 1. Compared with the prior art, the present invention uses a conveying pipe for unloading, and the pusher inclined plate in the anti-blocking structure is used to push the powdered raw materials during the rotation of the secondary shaft. Moreover, the rotation of the secondary shaft can not only drive the synchronous rotation of the guide plate and the pusher inclined plate, but also make the guide plate slide up and down on the secondary shaft through the base during the rotation, so that the pusher inclined plate slides synchronously, and the agglomerated powdered raw materials are broken up by the different motion trajectories between adjacent pusher inclined plates, which solves the problem that the spiral conveying mechanism installed in the traditional unloading structure easily causes the raw materials to agglomerate between adjacent spiral conveying blades during the conveying of raw materials, thereby affecting the subsequent processing technology.
[0015] 2. Compared with the prior art, the present invention is provided with a resetter, which can always ensure that the bottom end of the guide plate can be in contact with the base, so that it is at the same height when not lifted, and can fall successfully after being lifted.
[0016] 3. Compared with the prior art, the present invention can further break up agglomerated powdered raw materials by arranging staggered pusher ramps on adjacent material guide plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.
[0024] The figure marks in the drawings of the specification include: hopper 1, main shaft 2, conveying pipe 3, guide plate 4, pusher inclined plate 5, pusher vertical plate 6, closed ring plate 7, bottom support 8, reset sleeve 9, secondary shaft 10, reset guide plate 11, flat spring 12, driven block 13, arc-shaped groove 14.
[0025] An anti-blocking material feeding structure, for example Figure 1 As shown:
[0026] The utility model comprises a conveying pipe 3 installed below the hopper 1 and in communication with the hopper 1 , an anti-blocking structure installed in the conveying pipe 3 , and a driving structure installed on the hopper 1 and used for driving the anti-blocking structure.
[0027] The conveying pipe 3 is placed into the feed port of the subsequent process equipment, and the top end of the conveying pipe 3 is connected to the bottom end of the hopper 1. A closed ring plate 7 is also sleeved on the outside of the conveying pipe 3. The closed ring plate 7 is placed above the feed port and closes the feed port to prevent dust from leaking from the feed port to the external environment when the powdered raw materials are introduced through the conveying pipe 3.
[0028] In this embodiment, the drive structure includes a support plate mounted on top of hopper 1, a drive motor mounted on the support plate, and a main shaft 2 coaxially connected to the output shaft of the drive motor. Spiral conveying blades are also mounted on the outer wall of main shaft 2. The outer diameter of the spiral conveying blades gradually decreases from the top of hopper 1 downward, and the outer diameter of the spiral conveying blades is equal to the inner diameter of hopper 1 at the corresponding height.
[0029] The anti-clogging structure includes a secondary shaft 10 connected to the bottom end of the main shaft 2 through a coupling, four guide plates 4 circumferentially installed on the secondary shaft 10, a number of pusher inclined plates 5 respectively welded on the guide plates 4, and a base installed at the bottom end of the conveying pipe 3 and used to lift the guide plates 4 back and forth in sequence.
[0030] There are four vertical chute grooves on the circumference of the secondary shaft 10. The inner side of the guide plate 4 is integrally formed with a slider that can be inserted into the chute and slide in the chute. The length of the slider is shorter than the length of the chute, and the two ends of the slider are respectively located on the inner side of the two ends of the guide plate 4. Figure 3 and Figure 4 As shown, a follower block 13 is integrally formed at the bottom end of the guide plate 4 , and the follower block 13 is an arc-shaped block protruding outward.
[0031] The base includes a bottom support 8 and connecting rods integrally formed around the bottom support 8 and connected to the bottom end surface of the conveying pipe 3. A channel for discharging the powdered raw material is formed between adjacent connecting rods. A receiving groove is coaxially defined on the bottom support 8 with the secondary shaft 10. The bottom ends of the secondary shaft 10 and the guide plate 4 are both located within the receiving groove, with the bottom end of the guide plate 4 positioned below the bottom end of the secondary shaft 10. The inner bottom surface of the receiving groove has two axially symmetrical arcuate grooves 14, each transitioning from the bottom surface of the adjacent receiving groove to an arcuate surface. The driven blocks 13 can be positioned within each of these arcuate grooves 14. The top of each bottom support 8 also has an upwardly angled groove formed into an inclined table. The top of the inclined table contacts the outer wall of the guide plate 4 and scrapes away any powdered raw material adhering to the outer wall of the guide plate 4.
[0032] Each guide plate 4 is welded with several equally spaced pusher plates 5 on its outer side, with four of them located in the same plane. In this embodiment, the pusher plates 5 are tilted counterclockwise and downward. A vertical pusher plate 6 is welded to the left bottom of each pusher plate 5. The outer walls of the pusher plates 5 and 6 conform to the inner wall of the conveying pipe 3. The bottom end of the lowest pusher plate 6 is flush with the bottom end of the conveying pipe 3.
[0033] In other embodiments, when the four guide plates 4 are located at the same height, the pusher ramps 5 can also be welded to the four guide plates 4 in sequence in an alternating manner, so as to further break up the agglomerated powdered raw materials.
[0034] A reset mechanism is also mounted on the top of the secondary shaft 10, which is used to press the guide plates 4 downward. This reset mechanism consists of a reset sleeve 9 coaxially mounted on the secondary shaft 10, four reset guide plates 11 welded to the inside of the reset sleeve 9, and flat springs 12 sleeved onto the reset guide plates 11. The tops of the guide plates 4 extend into the reset sleeve 9, where they contact the deformable springs. The outer walls of the guide plates 4 mate with the inner walls of the reset sleeve 9. The bottom of the reset sleeve 9 also features an integrally formed inclined surface to scrape away powdered material adhering to the outside of the guide plates 4.
[0035] When the utility model is used, first cover the closed ring plate 7, then start the driving motor to rotate its output shaft counterclockwise and pour the powdered raw materials. The powdered raw materials enter the conveying pipe 3 from the bottom of the hopper 1, are pushed by the spiral conveying blades in the hopper 1, and are pushed by the pusher inclined plate 5 in the conveying pipe 3;
[0036] When the powdered raw material moves into the conveying pipe 3, the push inclined plate 5 will be driven by the rotation of the secondary shaft 10 to rotate synchronously with the guide plate 4 and have the function of rotation. During the rotation of the secondary shaft 10, the guide plate 4 will continue to be squeezed downward by the flat spring 12 in the reset sleeve 9, and the driven block 13 at the bottom end of the guide plate 4 will always fit the inner bottom surface of the accommodating groove in the bottom pillar 8, and will reciprocate through the arc groove 14 opened on the bottom surface of the accommodating groove, so that the guide plate 4 can have the function of sliding up and down while rotating synchronously with the secondary shaft 10, thereby driving the push inclined plate 5 and the push vertical plate 6 to slide up and down while rotating around the secondary shaft 10, and while pushing the powdered raw material to the bottom end of the conveying pipe 3, the agglomerated powdered raw material can be broken up through the different motion trajectories between adjacent push inclined plates 5, and there is a gap between adjacent push vertical plates 6, forming more channels for raw material discharge, so that it can move the discharge more dispersedly.
[0037] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
