Discharging and distributing device for cylindrical materials

Abstract

The utility model discloses a discharging and distributing device for cylindrical materials. A plurality of discharging grooves are used for receiving the lower portion of a discharging port of a material storage cavity. Each discharging groove is composed of two parallel groove walls, and at least one movable groove wall is included in the two groove walls forming each discharging groove. The movable groove wall moves up and down; and when the movable groove wall moves up and down, the top ends of the two groove walls forming each discharging groove have a height difference. When the movable groove wall moves up and down, the material bridge arching phenomenon at the upper end of the discharging groove is effectively damaged; a height difference exists between the top ends of the two groove walls forming each discharging groove, and equivalently, a feeding opening of the discharging groove is enlarged; meanwhile, under the condition that multiple discharging grooves exist, when the discharging groove in the left side of the movable groove wall is blocked, the materials can fall into the discharging groove in the right side of the movable groove wall, and vice versa; therefore, by means of the factors, the material blocking at the feeding port of the discharging groove can be effectively avoided, and the material distributing efficiency is effectively improved.

Description

Technical Field

[0001] The utility model relates to a material discharging and dividing device for cylindrical materials. Background Art

[0002] In many industrial production processes, it is necessary to separate cylindrical materials in a material storage cavity.

[0003] For example, in the fireworks industry, a large number of scattered paper tubes or plastic tubes need to be sorted, arranged and bundled in a certain shape, and then processed in the next step. The machines that complete the above work are called tube bundling machines, tube washing machines, etc. For example, the Chinese patent document "An automatic tube washing machine" with announcement number CN 201155953Y, the Chinese patent document "A firecracker and firework tube cake forming and bundling equipment" with announcement number CN102162711A, and the Chinese patent document "A vertical firework tube cake forming machine" with publication number CN103968716A. In this type of equipment, the material sorting hopper, storage chamber, feeding trough, and forming mold are arranged in sequence from top to bottom to form a cylinder flow channel: the messy paper tubes are sorted in the material sorting hopper by shaking or vibrating, and the paper tubes are sorted into a horizontal state (i.e., a horizontally fallen state) and neatly stacked in the storage chamber, and then the cylinders are sequentially sent into each feeding trough by their own weight to form a separate arrangement; the cylinders enter the forming mold of the cylinder cake forming mechanism along the feeding trough, and after the cylinders fill the forming mold, they are manually tied to form cylinder cakes. In the above process, the cylinders in the storage cavity are sent into each feeding trough to form a separate arrangement, which is the material sorting process.

[0004] The main drawback of the existing device is that when cylindrical materials (such as barrels) enter the distribution trough from the storage cavity, the distribution is not smooth due to the narrowing of the channel and the material bridge arch (also known as bridging, which is a phenomenon that materials will not fall even if suspended in the air due to mutual squeezing and overlapping between materials). Even if a vibrator is used to clear the congestion at the feed inlet of the distribution trough, the distribution efficiency still needs to be improved. Utility Model Content

[0005] In order to solve the above-mentioned drawbacks, the technical problem to be solved by the present invention is to provide a material discharging and distributing device for cylindrical materials, which effectively improves the material distributing efficiency. In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is a material discharging and distributing device for cylindrical materials, comprising a material storage chamber, characterized in that a plurality of material discharging troughs are provided below the material discharge port of the storage chamber; each material discharging trough is composed of two parallel trough walls, and the two trough walls constituting each material discharging trough include at least one movable trough wall; the movable trough wall moves up and down; when the movable trough wall moves up and down, the top ends of the two trough walls constituting each material discharging trough have a height difference.

[0006] The beneficial effect of the utility model lies in that, by adopting the above-mentioned technical scheme, when the movable trough wall moves up and down, the material bridge arch phenomenon at the upper end of the feed trough is effectively destroyed; the top ends of the two trough walls constituting each feed trough have a height difference, which is equivalent to enlarging the feed inlet of the feed trough; at the same time, in the case of multiple feed troughs, when the feed trough on the left side of the movable trough wall is blocked, the material can fall into the feed trough on the right side of the movable trough wall, and vice versa; therefore, taking the above-mentioned factors into consideration, the utility model can effectively avoid material congestion at the feed inlet of the feed trough and effectively improve the material distribution efficiency.

[0007] In one embodiment, the two slot walls constituting the material discharge slot are both movable slot walls, so as to better avoid congestion and improve efficiency.

[0008] In one embodiment, each feed trough is composed of a first movable trough wall and a second movable trough wall, the first movable trough wall and the second movable trough wall are spaced apart, a plurality of first movable trough walls are connected to a first connecting member, a plurality of second movable trough walls are connected to a second connecting member, and the first connecting member and the second connecting member are connected to a lifting drive mechanism. Further, the lifting drive mechanism includes two rollers respectively mounted on the first connecting member and the second connecting member, the two rollers are embedded in the curved groove of the cam, and the cam is connected to the rotating drive member. Further, the first connecting member and the second connecting member are mounted on a lifting guide rail. The mechanism is simple and the operation is efficient and reliable.

[0009] In one embodiment, the cylindrical material is a firework tube, such as a paper tube or a plastic tube.

[0016] See attached Figure 1-4 , reflecting a specific structure of the utility model. In the exemplary cylindrical material discharging and distributing device, the cylindrical material is a firework tube 1 (such as a paper tube or a plastic tube). The device includes a storage chamber 2 of the firework tube 1, and thirteen discharging troughs 3 are provided below the discharge port of the storage chamber 2; the storage chamber 2 and the discharging troughs 3 are installed on the back plate 4 at the rear side, and a panel (not shown in the figure) can be provided on the front side of the storage chamber 2 and the discharging troughs 3 for sealing to prevent the firework tube 1 from falling off from the front side.

[0017] A large number of firework tubes 1 are neatly stacked in a horizontal state (i.e., in a horizontally lying state) in the storage chamber 2. In a normal working state, the firework tubes 1 should fill the storage chamber 2. In the attached figure, only a small number of firework tubes are shown for a clear structure. The material distribution is the process of sequentially placing the firework tubes 1 in the storage chamber 2 into each material discharge trough 3 based on the deadweight of the firework tube 1, thereby forming a column arrangement. In a normal working state, the firework tubes 1 should fill each material discharge trough 3. In the attached figure, only a small number of firework tubes are shown for a clear structure.

[0018] Each material discharge chute 3 is composed of two parallel chute walls. In the example, thirteen material discharge chutes 3 are composed of fourteen chute walls.

[0019] In the utility model, the two trough walls constituting each material discharge trough include at least one movable trough wall; in the example, the two trough walls constituting the material discharge trough 3 are both movable trough walls to better avoid congestion and improve efficiency.

[0020] The movable groove wall moves up and down. In the example, each feed chute 3 is composed of a first movable groove wall 5 and a second movable groove wall 6, and seven first movable groove walls 5 and seven second movable groove walls 6 are distributed at intervals. The lifting and lowering movements of the first movable groove wall 5 and the second movable groove wall 6 are not synchronized, so when moving up and down, the top ends of the two groove walls constituting each feed chute 3 can have a height difference.

[0021] In the example, the seven first movable groove walls 5 are connected to the first connecting member 7 through the first connecting arm 51, and the seven second movable groove walls 6 are connected to the second connecting member 8 through the second connecting arm 61. The first connecting member 7 and the second connecting member 8 are connected to the lifting drive mechanism. In the example, the lifting drive mechanism includes two rollers 9 respectively mounted on the first connecting member 7 and the second connecting member 8, and the two rollers 9 are embedded in the curved groove 101 between the cam 10 and the outer ring of the cam. The cam 10 is connected to the rotary drive motor (not shown in the figure). In the example, the first connecting member 7 and the second connecting member 8 are mounted on the lifting guide rail 12. Through the simple mechanism setting, the asynchronous lifting and lowering driving work of the first movable groove wall 5 and the second movable groove wall 6 is realized, which is efficient and reliable.

[0022] In the example, two auxiliary connecting members 13 are installed on the lifting guide rail 12, and each of the first movable groove wall 5 and the second movable groove wall 6 is also connected to an auxiliary connecting member 13, so that the lifting movement is smoother.

[0023] The working principle of the above technical solution is:

[0024] like Figure 4 When the first movable groove wall 5 moves upward, it is higher than the two adjacent second movable groove walls 6, and can push the fireworks tubes piled up above, thereby effectively destroying the material bridge arch phenomenon at the upper end of the lower chute 3;

[0025] Moreover, since the top ends of the two trough walls constituting each feed trough 3 have a height difference, at this time, since the spacing L is greater than the spacing H, it is equivalent to enlarging the feed opening of the feed trough 3;

[0026] At the same time, due to the existence of the above-mentioned height difference, in the case of multiple feed chutes 3, when the feed chutes 3-1 on the left side of the first movable trough wall 5 are blocked, the firework tube can fall into the feed chutes 3-2 on the right side of the first movable trough wall 5, and vice versa;

[0027] Therefore, considering the above factors, the utility model can effectively avoid material congestion at the feeding port of the feeding chute and effectively improve the material distribution efficiency.

[0028] In other embodiments, a movable groove wall, such as a second movable groove wall 6, may be provided in the two groove walls constituting each material discharge trough, and the other groove wall may be a stationary groove wall, such as the first movable groove wall 5; when the movable groove wall moves up and down, the top of the movable groove wall is higher / lower than the stationary groove wall, so that the tops of the two groove walls constituting each material discharge trough 3 have a height difference.

[0029] The embodiments of the utility model disclosed above are only used to help illustrate the utility model. The embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification.

However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is only limited by the claims and their full scope and equivalents, and is not limited by the specific embodiments disclosed.
