Description

Technical Field

[0001] The utility model belongs to the technical field of particle packaging machines, and particularly relates to a feeding device for a granulator. Background Art

[0002] A particle packaging machine is a machine that can automatically complete all operations such as metering, bag making, filling, sealing, printing batch numbers, cutting, and counting. The particle packaging machine can automatically complete the packaging of fine particle materials, and is mainly used for packaging the following products or similar products: fine particulate matters such as granular medicines, sugar, coffee, fruit juice powder, tea, monosodium glutamate, salt, and seeds.

[0003] In the process of implementing the present utility model, the inventor found that there are at least the following problems in this technology: in the current particle packaging machine, when the feeding device for transporting materials pre-treats and crushes the materials, the crushing knife usually extends into the space where the materials are located for crushing to achieve the pre-treatment crushing of the materials. However, the problem is that the crushing knife cannot directly contact the inner wall of the cavity containing the materials, resulting in the materials at the bottom not being able to receive the crushing effect of the crushing knife, and the crushing effect is poor.

[0004] Therefore, we propose a feeding device for a granulator to solve the above problems. Summary of the Utility Model

[0005] The main purpose of the present utility model is to provide a feeding device for a granulator, which avoids the problem that the materials at the bottom cannot be touched by the crushing blade in the prior art. When the particles become very small after being crushed, they automatically fall from the filter screen and are discharged, which can effectively solve the problems in the background art.

[0006] In order to achieve the above purpose, the present utility model adopts the following technical solutions:

[0007] The feeding device for a granulator includes a feeding tank and a feeding treatment mechanism located in the feeding tank. An inlet pipe is fixedly connected to the top wall of the feeding tank, and an outlet pipe is fixedly connected to the bottom wall of the feeding tank. An upper support and a filter screen are integrally welded in the inner cavity of the feeding tank. The whole formed by the upper support and the filter screen is designed in a ring shape, and both sides of the upper support are welded to the inner wall of the feeding tank, so that both the upper support and the filter screen are kept stable and immobile.

[0008] Extension rods are symmetrically welded to the top wall of the inner cavity of the feeding tank. A first motor is horizontally installed on one of the extension rods. The output shaft of the first motor is coaxially connected to an inner support shaft. A collar is fixedly welded on the inner support shaft, and the inner support shaft and the collar are coaxially designed. Side extension rods are symmetrically welded on both sides of the collar. The feeding treatment mechanism includes turning plates respectively welded on the opposite sides of the two side extension rods, second motors respectively installed on the opposite side walls of the feeding tank, edge shafts respectively coaxially connected to the output shafts of each second motor, and crushing blades respectively welded on each edge shaft.

[0009] As a preferred embodiment, an internal feed inlet is provided at the top of the upper support, and the internal feed inlet is located directly below the feed pipe; so that all the materials added through the feed pipe can enter the inner space of the upper support through the internal feed inlet.

[0010] As a preferred embodiment, the thickness of the filter screen gradually decreases from its edge to the center, that is, the thickness at the bottom of the filter screen is the smallest; so that when the materials fall on the bottom of the filter screen again after being crushed by the crushing blades, they can easily pass through the filter screen and be discharged, reducing the blockage of the materials.

[0011] As a preferred embodiment, a protective shell is sleeved outside the first motor, and the protective shell is welded to the extension rod; so that the protective shell can protect the first motor. In actual design, it should be noted that a heat dissipation opening is provided at the bottom of the protective shell to assist in the heat dissipation of the first motor. Both the first motor and the second motor need to be powered by external power facilities.

[0012] As a preferred embodiment, the two turning plates are symmetric on both sides of the collar, and the curvature of the outer wall of the turning plate is the same as the curvature of the inner wall of the filter screen; and the turning plate is close to the filter screen, so that when the turning plate touches the materials on the filter screen, the materials can be lifted up.

[0013] As a preferred embodiment, a plurality of second motors are provided and symmetric on both sides of the feeding tank; the purpose of setting a plurality of second motors is to set more crushing blades, so as to cover the crushing work of materials in a larger range.

[0014] As a preferred embodiment, all the edge shafts are horizontally arranged and rotatably connected to the feeding tank, and a plurality of crushing blades are arranged at equal intervals on each edge shaft; the number of crushing blades is large and they are distributed on both sides of the inner cavity of the feeding tank, which is convenient for crushing the lifted materials. Refer to the attached Figure 2 It can be seen that the lengths of the two edge shafts located at the center are reduced, and the number of crushing blades on them is also reduced, which is to avoid conflicts with structures such as the first motor.

[0015] In summary, the technical effects and advantages of the present utility model are as follows:

[0016] For this granulator feeding device, by driving the first motor to operate, the turning plate continuously lifts the materials above the filter screen, so that the materials are lifted into the air and are crushed by the crushing blades on both sides. The crushing effect is better and more thorough, thus avoiding the problem that the materials located at the bottom cannot be touched by the crushing blades in the prior art. When the materials are crushed into very small particles, they automatically fall from the filter screen and are discharged; in addition, by lifting the materials above the filter screen with the turning plate, the problem of material blockage on the filter screen can also be avoided;

[0017] For the feeding device of the granulator, under the continuous flipping action of two turning plates, the materials on the filter screen will be lifted into the air and crushed by the crushing blades. The materials that become very small particles after crushing will pass through the filter screen and be discharged from the discharge pipe, while the uncrushed materials will continuously be flipped by the turning plates and crushed by the crushing blades until they become fine particles and pass through the filter screen, achieving rapid crushing of the materials.

Specific Embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-3 , the feeding device of the granulator includes a feeding tank 1 and a feeding processing mechanism located inside the feeding tank 1. A feed pipe 2 is fixedly connected to the top wall of the feeding tank 1, and a discharge pipe 3 is fixedly connected to the bottom wall of the feeding tank 1. An integrally welded upper support 11 and a filter screen 12 are provided in the inner cavity of the feeding tank 1. The overall formed by the upper support 11 and the filter screen 12 is in a ring design, and both sides of the upper support 11 are welded to the inner wall of the feeding tank 1, so that both the upper support 11 and the filter screen 12 are kept stable. The thickness of the filter screen 12 gradually decreases from its edge to the center, that is, the thickness at the bottom of the filter screen 12 is the smallest, so that it is very easy for the materials to pass through the filter screen 12 and be discharged when they fall on the bottom of the filter screen 12 again after being crushed by the crushing blade 16, reducing the blockage of the materials; and, an internal feed port 13 is opened at the top of the upper support 11, and the internal feed port 13 is located directly below the feed pipe 2, so that all the materials added through the feed pipe 2 can enter the inner space of the upper support 11 through the internal feed port 13;

[0024] Extension rods 4 are symmetrically welded to the top wall of the inner cavity of the feeding tank 1. A first motor 5 is horizontally installed on one of the extension rods 4. A protective housing 6 is sleeved outside the first motor 5, and the protective housing 6 is welded to the extension rod 4, so that the protective housing 6 can protect the first motor 5. In actual design, it should be noted that a heat dissipation opening is provided at the bottom of the protective housing 6 to assist in the heat dissipation of the first motor 5. The output shaft of the first motor 5 is coaxially connected to an inner support shaft 7. A collar 8 is fixedly welded on the inner support shaft 7, and the inner support shaft 7 and the collar 8 are coaxially designed. Side extension rods 9 are symmetrically welded on both sides of the collar 8. The feeding processing mechanism includes turning plates 10 respectively welded on the opposite sides of the two side extension rods 9, second motors 14 respectively installed on the opposite side walls of the feeding tank 1, edge shafts 15 respectively coaxially connected to the output shafts of each second motor 14, and crushing blades 16 respectively welded on each edge shaft 15. The first motor 5 and the second motor 14 both require external power facilities for power supply;

[0025] A plurality of second motors 14 are provided and are symmetric on both sides of the feeding tank 1. The purpose of providing a plurality of second motors 14 is to provide more crushing blades 16, so as to cover the crushing work of materials in a larger range. All the edge shafts 15 are horizontally arranged and rotatably connected to the feeding tank 1. A plurality of equally spaced crushing blades 16 are provided on each edge shaft 15. The number of crushing blades 16 is large and they are distributed on both sides of the inner cavity of the feeding tank 1, which is convenient for crushing the lifted materials. Refer to the appendix Figure 2 It can be seen that the lengths of the two edge shafts 15 located at the center are reduced, and the number of crushing blades 16 on them is also reduced, which is to avoid conflicts with structures such as the first motor 5;

[0026] The two turning plates 10 are symmetric on both sides of the collar 8, and the curvature of the outer wall of the turning plate 10 is the same as the curvature of the inner wall of the filter screen 12, and the turning plate 10 is close to the filter screen 12, so that the turning plate 10 can lift the materials when it contacts the materials on the filter screen 12.

[0027] The feeding device of this granulator: When in use, the first motor 5 and multiple second motors 14 are driven to operate together. Among them, the operation of the first motor 5 drives the inner support shaft 7, the collar 8, two side extension rods 9 and two turning plates 10 to rotate uniformly. At this time, the material to be crushed is added through the feed pipe 2, so that the material falls on the inner sides of the upper support 11 and the filter screen 12 after passing through the internal feed port 13. At this time, since the multiple second motors 14 have driven the crushing blades 16 on them to rotate at high speed, part of the material is directly crushed by the crushing blades 16. The uncrushed material will fall to the bottom of the filter screen 12. Under the continuous turning of the two turning plates 10, the material on the filter screen 12 will be lifted into the air and crushed by the crushing blades 16; after being crushed in this way, the material with very small particles will pass through the filter screen 12 and be discharged from the discharge pipe 3, while the uncrushed material will continue to be turned by the turning plates 10 and crushed by the crushing blades 16 until the particles become fine and then pass through the filter screen 12. In this way, it can avoid the problem that the material at the bottommost part on the filter screen 12 cannot be touched by the crushing blades 16, and the turning of the turning plates 10 can also avoid the blockage of the micropores on the filter screen 12 by the material.

[0028] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
