Description

Technical Field

[0001] The present invention relates to the technical field of filling and packaging machines, and in particular to a material residue-free follow-up unloading device. Background Art

[0002] The unloading of a filling and packaging machine refers to the process of filling materials into the packaging bag through a unloading device. In order to improve the filling efficiency, most of the existing technologies adopt a follow-up unloading device, that is, the unloading funnel is set to follow the packaging bag during the packaging bag conveying process to move and unload the material.

[0003] However, the follow-up unloading device of the filling and packaging machine currently on the market cannot completely pour out the material, and the material will remain inside the guide bin, which makes cleaning more laborious. Secondly, the existing follow-up unloading device cannot accurately detect the material height when introducing the material into the funnel. Some use electric valves or pneumatic valves for control, but require the addition of external power, resulting in a complex overall structure and high energy consumption. In addition, the dust removal process during unloading in the existing device also has certain defects. The inlet of the dust suction pipe is directly aligned with the unloading port position of the unloading funnel, which has the problem of poor dust collection effect. Dust removal and cleaning are required later, which is time-consuming and labor-intensive. Summary of the Invention

[0004] The main purpose of the present invention is to provide a material residue-free follow-up unloading device to overcome the problems existing in the prior art.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A material residue-free follow-up discharge device comprises a material guide assembly, a discharge funnel assembly and a dust removal assembly. The material guide assembly rotates following the turntable of the filling machine, the discharge funnel assembly is arranged at the lower part of the material guide assembly, and the dust removal assembly is arranged at the lower part of the discharge funnel assembly. The material guide assembly includes a fixed cylinder, a conical material guide bin and an upper cover. A plurality of the conical material guide bins are evenly arranged along the circumference of the fixed cylinder, and the upper cover is arranged on the top of the conical material guide bin.

[0006] Furthermore, the cone angle of the conical material guide bin is ≥70°, so that the material inside the conical material guide bin can fall out completely.

[0007] Furthermore, the upper cover is provided with a feed opening and an air outlet, and the feed opening and the air outlet are arranged opposite to each other.

[0008] Furthermore, a breathable cover is provided on the outside of the air outlet.

[0009] Furthermore, the discharge funnel assembly includes a connecting tube and a plurality of funnels uniformly arranged along the circumference of the outer side of the connecting tube, and the feed port of the funnel is connected to the discharge port of the conical guide bin.

[0010] Furthermore, a material level control valve is provided at the feed inlet of the funnel, and the material level control valve adopts a passive valve, which includes a control valve body and a valve hinged at the bottom opening of the body; When the material in the conical guide bin enters the funnel, the material level control valve is initially in an open state. As the material level in the funnel increases, the material pushes the valve of the material level control valve upward, causing the valve opening to gradually decrease until it is completely closed.

[0011] Furthermore, the dust removal assembly includes a dust hood and a dust suction pipe. The dust hood is located at the outlet of the discharge pipe of the funnel, and the dust suction pipe is evenly arranged along the outer circumference of the connecting tube. One end of the dust suction pipe is aligned with the outlet of the dust hood, and the other end is connected to the dust suction device inside the connecting tube.

[0012] Furthermore, the dust hood adopts a spiral volute dust hood, and the dust suction pipe adopts a steel wire hose.

[0013] Furthermore, a plurality of fixing boxes are arranged on the circumferential outer side of the connecting cylinder, a funnel segment is provided at the outlet of the discharge pipe of the funnel, the funnel segment is connected to the fixing box, and the dust removal cover is sleeved on the outer side of the funnel segment.

[0014] Compared with the prior art, the present invention has the following beneficial effects: (1) By adopting a conical guide silo, the material inside the guide silo is made to fall out more easily by utilizing its larger inclination angle. In addition, the conical guide silo adopts a suitable taper, and the cone angle of the conical guide silo is ≥70°, so that the material inside the guide silo falls out completely, achieving the effect of no residue of the filling material, and no need for laborious cleaning; (2) The material level control valve adopts a passive valve. As the material level in the funnel gradually increases, the material will push the valve of the material level control valve upward, causing the valve opening to gradually decrease until it is completely closed. The material level can be controlled without external power, reducing energy consumption. In addition, the material level in each funnel can be basically consistent, the pressure on the funnel is consistent, and the material discharge speed is consistent, achieving the effect of accurately controlling the amount of material poured in; (3) The dust removal system was further optimized by using a spiral volute dust hood, which made the outlet of the dust hood closer to the dust collection pipe, making the suction force of the dust collection pipe stronger and the dust removal effect better.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0024] Combine Figures 1 to 7 This embodiment provides a material residue-free following discharge device, including a material guide component 1, a discharge funnel component 2 and a dust removal component 3. The material guide component 1 rotates following the turntable of the filling machine, the discharge funnel component 2 is arranged at the lower part of the material guide component 1, and the dust removal component 3 is arranged at the lower part of the discharge funnel component 2.

[0025] Specific reference Figures 2 to 3 The material guide assembly 1 comprises a fixed cylinder 11, a conical guide bin 12, and a top cover 13. Multiple conical guide bins 12 are evenly spaced around the fixed cylinder 11, and the top cover 13 is located on top of each conical guide bin 12. The conical guide bins 12 are tapered to ensure complete discharge of the material within. By adjusting the inclination angle of the conical guide bins to ≥70°, the material is completely discharged, achieving a zero-residue filling effect.

[0026] In this embodiment, the upper cover 13 is provided with a feed opening 14 and an air outlet 15 , and the feed opening 14 and the air outlet 15 are arranged opposite to each other.

[0027] In a further embodiment, a breathable cover 16 is provided on the outer side of the air outlet 15 .

[0028] Specific reference Figures 4 and 5The discharge funnel assembly 2 includes a connecting tube 21 and a plurality of funnels 22 evenly arranged along the circumference of the outer side of the connecting tube 21 . The feed port of the funnel 22 is connected to the discharge port of the conical guide bin 12 .

[0029] In this embodiment, a material level control valve 23 is provided at the feed port of the funnel 22. The material level control valve 23 adopts a passive valve, which includes a control valve body and a valve hinged at the bottom opening of the body; when the material of the conical guide bin 12 enters the funnel 22, the material level control valve 23 is initially in an open state. As the material level height in the funnel 22 increases, the material will push the valve of the material level control valve 23 upward, causing the valve opening to gradually decrease until it is completely closed.

[0030] The passively controlled material level control valve does not require power to control the material level, which reduces energy consumption. It can also make the material level in each funnel basically consistent, the pressure on the funnel consistent, and the material discharge speed consistent, thus achieving the effect of accurately controlling the amount of material poured in.

[0031] Specific reference Figures 6 and 7 The dust removal assembly 3 includes a dust removal hood 31 and a dust suction pipe. The dust removal hood 31 is located at the outlet of the discharge pipe of the funnel 22. The dust suction pipe is evenly arranged along the outer circumference of the connecting tube 21. One end of the dust suction pipe is aligned with the outlet of the dust removal hood 31, and the other end is connected to the dust suction device inside the connecting tube 21.

[0032] In this embodiment, the dust hood 31 adopts a spiral volute dust hood, and the dust suction pipe adopts a steel hose. With this solution, the outlet of the dust hood is closer to the dust suction pipe, making the dust suction pipe suction stronger and the dust removal effect better.

[0033] In a further embodiment, a plurality of fixed boxes 24 are arranged on the circumferential outer side of the connecting cylinder 21, a funnel segment 25 is provided at the outlet of the discharge pipe of the funnel 22, the funnel segment 25 is connected to the fixed box 24, and the dust cover 31 is sleeved on the outer side of the funnel segment 25.

[0034] Working principle: During filling, the material is poured in from the discharge port 14, 15 is the air outlet, the upper cover 13 remains stationary, and the conical guide bin 12 rotates with the turntable; the present invention uses a conical guide bin 12 with a smooth surface and a suitable taper, so that all the materials can fall down without any residue; after the material enters the funnel from the conical guide bin 12, the material level control valve 23 is initially open. As the material level increases, the valve opening against the material level control valve 23 is gradually reduced until it is completely closed. This way, the pressure on each funnel can be the same, ensuring consistent discharge speed; finally, the device adopts a spiral volute dust collector 31, which is placed below the funnel 22 and is closer to the steel hose, has stronger suction, greatly improves dust removal efficiency, and is more beautiful than before.

[0035] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
