Description

Technical Field

[0001] The utility model relates to the technical field of filling and packaging, in particular to a vertical full-automatic filling and packaging machine. Background Art

[0002] The filling and packaging machine uses pressure, gravity, fluid, etc. to quantitatively fill powders, liquids, colloids and other products into corresponding containers, and then seals the containers to complete the packaging operation.

[0003] For the powder filling process, the quantitative powder is blown into the container by the air flow pressure. It should be noted that the powder particles are fine and will generate dust under the action of the air flow pressure, which will not only affect the working environment, but also cause the problem of powder waste. The conventional measure is to temporarily block the container opening. However, in the process of injecting powder, the volume of the container is compressed as the air flow and powder are filled into the container. It can be understood that a pressure difference is formed between the inside and outside of the container. After the powder injection action is completed, the powder is blown out of the container in the opposite direction under the action of the pressure difference. The above-mentioned problems of affecting the working environment and wasting powder still exist.

[0004] This application proposes a solution to this problem. Utility Model Content

[0005] The utility model aims to provide a vertical fully automatic filling and packaging machine, which aims to solve the problem that in the current powder filling operation, under the action of airflow and pressure difference, the powder is backblown during the filling process, which affects the working environment and wastes the powder.

[0006] The purpose of the utility model can be achieved through the following technical solutions: A vertical fully automatic filling and packaging machine, including a silo, a primary electric push rod and a plurality of injection components, the injection components including a primary barrel, a secondary barrel, a sliding material tube, a joint sleeve, a third-level electric push rod, a secondary electric push rod and an injection tube, the joint sleeve is located at the junction of the primary barrel, the sliding material tube and the secondary barrel, and the sliding material tube is connected to the inside of the silo;

[0007] There are two injection tubes, and an intermediate sliding tube is slidably installed between the two injection tubes. One of the injection tubes located at the upper side is installed on the secondary barrel, and a directional sleeve is installed on the outside of the injection tube located at the upper side, and a rubber leather cover is installed on the lower end of the directional sleeve. An air inlet pipe corresponding to the directional sleeve is installed inside the secondary barrel.

[0008] It is further configured as follows: a material distribution ball is arranged inside the joint sleeve, and the material distribution ball is rotatably connected in the joint sleeve through a three-stage electric push rod.

[0009] It is further configured as follows: piston blocks are slidably installed in the inner wall of the first-stage barrel and the inner wall of the air-increasing pipe, and the output shafts of the first-stage electric push rod and the second-stage electric push rod are fixedly connected to the piston blocks in the corresponding positions.

[0010] It is further configured as follows: the length of the rubber sleeve along the length direction of the middle sliding tube is smaller than the length of the middle sliding tube, and the rubber sleeve does not contact the middle sliding tube, and the lower side of the rubber sleeve is fixedly connected to the injection tube located at the lower side.

[0011] It is further configured as follows: a plurality of air pipes are arranged between the lower end of the air boost pipe and the directional sleeve, and the air boost pipe and the directional sleeve are connected through the air pipe, and the lower end of the injection pipe located at the lower side is lower than the lower end of the rubber sleeve.

[0012] The utility model has the following beneficial effects:

[0013] 1. The overall structure adopts an air expansion auxiliary method for the powder filling process, which is as follows: before the powder is blown in, the rubber sleeve is filled with air, but the space for blowing in the powder is reserved. During the continuous blowing in of the powder, the volume of the rubber sleeve is reduced in an adaptive manner with the filling action, ensuring that the powder is always in the space between the rubber sleeve and the bottom of the container during the blowing process. The purpose is to avoid the problem of dust generated when blowing in the powder, thereby avoiding the waste of powder and the problem of affecting the working environment;

[0014] 2. In combination with the above content, it is reiterated that: with respect to the movement process of the injection tube and the rubber holster, the injection tube can be directional moved in conjunction with the intermediate sliding tube. The purpose is to cooperate with the movement process of the container relative to the injection tube during the filling process, and the movement process of the injection tube can also be used to further limit the expansion / reset deformation process of the rubber holster, specifically to maintain the internal volume of the container and avoid powder flying due to pressure difference.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1

[0024] In the process of powder filling, as the airflow and powder are filled into the container, the container volume is compressed. It can be understood that: a pressure difference is formed inside and outside the container. After the powder injection action is completed, the powder is blown out of the container in the opposite direction under the action of the pressure difference. There are the above-mentioned problems of affecting the working environment and wasting powder. The following technical solutions are proposed:

[0025] Reference Figures 1 to 5 In this embodiment, a vertical fully automatic filling and packaging machine includes a silo 1, a primary electric push rod 2 and a plurality of injection components, the injection components include a primary barrel 4, a secondary barrel 5, a sliding tube 6, a joint sleeve 11, a tertiary electric push rod 7, a secondary electric push rod 3 and an injection tube 9, the joint sleeve 11 is located at the intersection of the primary barrel 4, the sliding tube 6 and the secondary barrel 5, and the sliding tube 6 is connected to the inside of the silo 1;

[0026] There are two injection tubes 9, and an intermediate sliding tube 13 is slidably installed between the two injection tubes 9. One of the injection tubes 9 located at the upper side is installed on the secondary barrel 5, and a directional sleeve 15 is installed on the outside of the injection tube 9 located at the upper side, and a rubber leather cover 8 is installed on the lower end of the directional sleeve 15. An air inlet pipe 12 corresponding to the directional sleeve 15 is installed inside the secondary barrel 5, and a distribution ball 10 is arranged inside the node sleeve 11. The distribution ball 10 is rotatably connected in the node sleeve 11 through the third-stage electric push rod 7. Piston blocks 14 are slidably installed on the inner wall of the primary barrel 4 and the inner wall of the air inlet pipe 12. The output shafts of the first-stage electric push rod 2 and the second-stage electric push rod 3 are fixedly connected to the piston blocks 14 in the corresponding positions.

[0027] Basic principle: Refer to Figure 1 and Figure 2 Explanation: The powder is contained in the silo 1 and flows out along the slide pipe 6. When the dividing ball 10 is opened, the powder flows along the slide pipe 6 into the secondary barrel 5. During the movement of the primary electric push rod 2, refer to Figure 3 The piston block 14 in the primary barrel 4 moves downward to generate pressure, and under the action of pressure, the powder is injected into the container through the injection pipe 9;

[0028] It should be noted that before the powder is injected, the injection tube 9 is placed inside the container. During this process, the rubber sheath 8 is inflated by the air inflating tube 12 until the rubber sheath 8 fills the inside of the container, which can be understood from the side as sealing the container.

[0029] Embodiment 2

[0030] This embodiment further explains the movement form in the secondary barrel:

[0031] The length of the rubber sheath 8 along the length direction of the middle slide tube 13 is smaller than the length of the middle slide tube 13, and there is no contact between the rubber sheath 8 and the middle slide tube 13. The lower side of the rubber sheath 8 is fixedly connected to the injection tube 9 located at the lower side. A plurality of air pipes are arranged between the lower end of the air increase pipe 12 and the directional sleeve 15, and the air increase pipe 12 and the directional sleeve 15 are connected through the air pipe. The lower end of the injection tube 9 located at the lower side is lower than the lower end of the rubber sheath 8.

[0032] Solution description: In combination with the first embodiment, it is also necessary to explain that: on a specific filling automatic line, after the container reaches the specified position, the entire injection assembly moves down to ensure that the injection tube 9 is placed in the container content. In this process, it is necessary to explain that there are the following two action modes:

[0033] A: The injection tube 9 located at the lower side is located at the bottom of the container. When the injection tube 9 located at the lower side is moved up to the maximum distance, during this process, the rubber sheath 8 is fully expanded and fits the inner wall of the container, and a gap is always maintained between the bottom of the container and the rubber sheath 8. Then, when the powder is injected, the entire injection assembly moves upward at a uniform speed, and the rubber sheath 8 is deflated, so that the expanded volume of the rubber sheath 8 becomes smaller but still fits the inner wall of the container, the gap aperture gradually increases, and the powder is continuously replenished, until after the powder injection is completed, the lower side of the rubber sheath 8 still remains in a state of fitting the container opening position;

[0034] B: Based on A, the injection tube 9 on the lower side contacts the bottom of the container, but the two injection tubes 9 maintain a maximum distance between them. It can be understood that the two injection tubes 9 are in an initial state by utilizing the expansion process of the rubber sheath 8, and then when the powder is injected, the rubber sheath 8 is deflated and the powder is continuously added to the gap. As the amount of powder increases, the powder can be used to push the rubber sheath 8, thereby driving the injection tube 9 on the lower side to move upward, until the powder filling action is completed, and the rubber sheath 8 still on the lower side contacts the container opening position.

[0035] In summary, the air expansion auxiliary method is adopted, which is manifested as: the container is filled with the rubber sheath after air expansion, and the rubber sheath is in a continuous resetting process during the process of blowing in the powder. Its purpose is: on the basis of not interfering with the blowing of the powder, the shape change of the rubber sheath is used to adapt the blowing volume of the powder, so as to prevent the waste of powder dust and pollution of the working environment.
