Description

Technical Field

[0001] The invention relates to an oil-soluble particle filling machine. Background Art

[0002] The filling of oil-soluble granular food, medicine, health care products, etc. requires filling equipment that matches the market demand in order to prevent pollution, produce quickly, and fill efficiently. After a domestic market survey, domestic manufacturers basically adopt a production method of filling granules first and then manually filling oil. That is, after using an ordinary solid particle filling machine to fill the particles, the oil is filled using a filling valve. The solid particle filling machine can use an existing funnel filling machine, and its structure will not be described in detail. The ordinary liquid filling machine includes a filling frame, a liquid tank is installed on the filling frame, and a plurality of filling valves are arranged on the liquid tank. The lower part of the liquid tank is connected to a filling support corresponding to the filling valve. The filling valve includes a valve body and a valve stem slidably installed in the valve body. A filling nozzle is provided at the bottom of the valve body. The gap between the bottom of the valve stem and the filling nozzle is the filling port. A double-stroke cylinder is installed on the top of the valve body. The top of the valve stem is connected to the double-stroke cylinder power. The filling port is opened by the cylinder action, so that the oil enters the bottle body. The problems of the filling machine with the above structure are as follows: 1. The filling of oil-soluble particles can only be achieved through two processes, which has low efficiency and high production costs. 2. Intermittent production operations are required according to process requirements, that is, after the solid particles are filled, the bottle body needs to be transferred again, which does not form a continuous automated production line and has low overall production efficiency. 3. The operation is cumbersome and the productivity is not high. Since the bottle mouth is in an open state during the transfer process, it is very easy to cause contamination during the filling process. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide an oil-soluble granule filling machine which can simultaneously fill oil and granules into a bottle, thereby improving production efficiency and reducing production, and can achieve continuous operation to avoid the problem of contamination of the filling material during the filling process.

The inner sleeve of the filling valve cylinder is connected to a filling valve stem whose upper end is connected to the inner cavity of the filling box and whose lower end extends to the lower part of the inner cavity of the inner sleeve. A filling liquid cavity is formed between the outer wall of the filling valve stem and the inner walls of the filling valve cylinder and the inner sleeve, and a sealing and openable filling port is formed between the outer wall of the filling valve stem and the lower end of the inner sleeve. A guide rod that can slide up and down is connected to the upper part of the inner sleeve, and a bottle guide cover is connected to the lower part of the guide rod. When the guide rod slides upward, the bottle guide cover can drive the inner sleeve to slide upward to open the filling port, and when the guide rod slides downward, the filling port can be closed. The bottle supporting rack is equipped with a bottle supporting shaft that can slide up and down, and the bottle support is connected to the bottle supporting shaft. The filling machine rack is equipped with a bottle body power mechanism that can drive the bottle supporting shaft to slide up and down, and when the bottle supporting shaft slides upward, the bottle body on the bottle support can lift up the bottle guide cover.

[0005] The guide cover is provided with a guide channel for the filling valve stem to extend downward, the lower outer surface of the filling valve stem is provided with a sealing seat, the outer surface of the sealing seat is provided with a filling sealing ring, the filling port is formed between the lower end of the inner sleeve and the filling sealing ring, a filling top spring is connected between the filling valve cylinder and the inner sleeve, and the lower part of the inner sleeve is provided with a locking block which can abut against the bottle guide cover so as to drive the inner sleeve to slide when the bottle guide cover rises.

[0006] The bottle guide cover is an inverted cone-shaped cover body, and a bottle mouth elastic pad is provided on the inner top surface of the bottle guide cover for sealing the bottle mouth of the bottle body. The filling valve stem is a hollow tube, and its lower end can extend into the bottle body and the upper end extends into the upper part of the inner cavity of the filling box.

[0007] A flow divider located in the inner cavity of the inner sleeve is arranged on the outer wall of the filling valve stem. The flow divider comprises a flow divider body and a plurality of flow divider fins arranged around the flow divider body.

[0008] The bottle body power mechanism comprises a guide box connected to the filling machine frame, a cam track is arranged on the guide box, a roller located in the cam track is arranged at the lower part of the bottle supporting shaft, and the bottle supporting shaft can move up and down when the roller slides in the cam track.

[0009] The bottle supporting rack is provided with a rotation-stopping plate which can prevent the bottle supporting shaft from rotating around its own axis.

After entering, the particles can be evenly dispersed in the oil under the dispersing effect of the particle dispersion rack, and the oil and particles both enter the filling liquid cavity. When the bottle body rotates with the bottle support to the bottom of the filling valve at the specified position, the bottle body on the bottle support can lift up the bottle guide cover when the bottle support shaft slides upward, and the bottle guide cover can drive the inner sleeve to slide upward when the guide rod slides upward to open the filling port, and the oil and particles both enter the bottle body on the bottle support from the filling port. After the filling is completed, the bottle support shaft falls, the bottle guide cover falls, and after the guide rod falls, the inner sleeve slides downward to close the filling port, thereby realizing the filling of one bottle body. As the filling power mechanism drives the bottle support rack to rotate continuously, the bottle body on the bottle support that reaches the specified position can be filled. It can be seen from the above-mentioned action process that the present invention can fill oil and particles into the bottle at the same time, and realize the filling of oil and particles in one step, which greatly improves the labor efficiency and avoids the problem of contamination of the filling material during the bottle transfer process.

[0013] In summary, the present invention can fill oil and particulate matter into the bottle at one time, and has the advantages of high labor efficiency, reduced production cost and high filling quality. BRIEF DESCRIPTION OF THE DRAWINGS

Specifically, in this embodiment, combined with Figure 2 As shown, an upper cover 25 is installed in the middle of the top of the filling box 2, and a filling top seat 24 located in the center thereof is rotatably connected inside the upper cover 25. The oil inlet pipe 21 and the particle inlet pipe 22 are both inserted on the filling top seat 24. Since two pipelines are provided, it is necessary to connect a rotary joint on the pipeline to prevent entanglement when the filling box rotates. However, this embodiment adopts the filling top seat and other structures of the above structure, and no rotary joint is required. The structure is simple and convenient for the input of granular materials. The granular inlet pipe 22 extends into the lower part of the inner cavity of the filling box 2.
