Description

Technical Field

[0001] The utility model relates to the field of filling machines, in particular to a self-priming induction device for a coupling agent filling machine. Background Technique

[0002] Filling machines are mainly a small category of products in packaging machines. From the perspective of packaging materials, they can be divided into liquid filling machines, paste filling machines, powder filling machines, and granule filling machines; from the degree of production automation, they are divided into semi-automatic filling machines and fully automatic filling production lines. Recently, with the QS certification of food, edible oil manufacturers have begun to pay attention to product quality and packaging, so oil filling machines have become prominent in filling machines.

[0003] For example, the authorized announcement number is CN 210882748 U, a self-priming liquid filling machine, belonging to the technical field of liquid filling. The liquid filling machine includes a fixing component, a material suction component, and a filling component. During filling, the driving telescopic member is driven to push the fixing plate downward, so that the second elastic member pushes the pressing plate to tightly seal the filling container. At this time, the first solenoid valve is opened, the second solenoid valve is closed, and the exhaust hole is evacuated by a vacuum pump, thereby evacuating the filling container. The liquid in the material suction housing enters the filling container through the discharge pipe, the guiding pipe, and the filling pipe until the liquid in the material suction housing is sucked out, and a single filling is completed. The device evacuates the air in the filling container to prevent bubbles and air from being mixed in during liquid filling. Even if some bubbles are generated during filling, the subsequent vacuum pump will still evacuate the air, ensuring the cleanliness of the product, and automatically sucking and filling the liquid through the vacuum pump, with a simple structure and convenient use.

[0004] The existing self-priming induction filling heads on filling machines are all directly inserted into the inside of the filling bottle for filling. Due to the large impact force of the liquid during filling and the lack of a sealing mechanism between the filling head and the bottle mouth, the liquid is easily splashed from the bottle mouth to pollute the environment; therefore, there is an urgent need in the market to develop a self-priming induction device for a coupling agent filling machine to help people solve the existing problems. Content of the Utility Model

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

[0023] Please refer to Figures 1-4, an embodiment provided by the present utility model: a self-priming induction device for a coupling agent filling machine, including a self-priming induction filling head 1. Inside the self-priming induction filling head 1, there is a self-priming cavity 101. In the middle of the upper end of the self-priming induction filling head 1, there is a feeding pipe 3. On one side of the self-priming induction filling head 1, a vacuum pump 2 is connected. On one side of the self-priming induction filling head 1, a pressure sensor 102 is fixedly connected. In the middle of the lower end of the self-priming induction filling head 1, a filling pipe 4 is fixedly connected. At the lower end of the self-priming induction filling head 1 and outside the filling pipe 4, a closing component 103 is provided. Inside the closing component 103, there is a telescopic cavity 104. At the lower end of the closing component 103 and outside the filling pipe 4, a telescopic pipe 5 is provided. At the lower end of the telescopic pipe 5 and outside the filling pipe 4, an annular rubber seal 501 is provided. On the lower end surface of the annular rubber seal 501, a conical groove 502 is provided.

[0024] Furthermore, a meter 301 is provided on the feeding pipe 3. The lower end of the feeding pipe 3 is communicated with the self-priming cavity 101. One end of the pressure sensor 102 extends into the self-priming cavity 101. During filling, the pressure inside the self-priming cavity 101 is detected by the pressure sensor 102.

[0025] Furthermore, between the vacuum pump 2 and the self-priming cavity 101 inside the self-priming induction filling head 1, they are communicated through an L-shaped suction pipe 201. On the upper end surface inside the self-priming cavity 101 and on one side of the L-shaped suction pipe 201, a U-shaped baffle 202 is fixedly connected. The vacuum pump 2 sucks the gas inside the self-priming cavity 101 through the L-shaped suction pipe 201, so that a negative pressure is formed inside the self-priming cavity 101. Through the negative pressure, the raw material in the storage tank enters the telescopic cavity 104 through the feeding pipe 3. The U-shaped baffle 202 blocks the nozzle of the L-shaped suction pipe 201 to prevent liquid from entering the L-shaped suction pipe 201.

[0026] Furthermore, four rectangular limit grooves 105 are annularly arranged on the inner side end surface of the telescopic cavity 104. The upper end of the telescopic pipe 5 extends into the telescopic cavity 104 and four rectangular limit parts 503 are annularly arranged on the side end surface.

[0027] Furthermore, the four rectangular limit parts 503 on the telescopic pipe 5 respectively slide into the four rectangular limit grooves 105, so that the telescopic pipe 5 can be retracted into the telescopic cavity 104. By sliding the rectangular limit parts 503 along the rectangular limit grooves 105, the stability of the movement of the telescopic pipe 5 is ensured.

[0028] Furthermore, a spring 106 is provided inside the telescopic cavity 104 at the upper end of the telescopic pipe 5. When the telescopic pipe 5 is retracted into the telescopic cavity 104, the spring 106 is compressed.

[0029] Furthermore, a sealing scraping ring 504 is provided between the middle of the annular rubber seal 501 and the filling pipe 4. The sealing scraping ring 504 is fixedly connected to the annular rubber seal 501. When the filling machine drives the self-priming induction filling head 1 to descend, the filling bottle mouth is inserted into the conical groove 502, restricting the descent of the annular rubber seal 501, so that the annular rubber seal 501 seals between the filling bottle mouth and the filling pipe 4, preventing the liquid from splashing out of the filling bottle and polluting the environment.

[0030] Working principle: During use, when the filling machine drives the self-priming induction filling head 1 to descend, the filling bottle mouth is inserted into the conical groove 502, restricting the descent of the annular rubber seal 501, so that the annular rubber seal 501 seals between the filling bottle mouth and the filling pipe 4, preventing the liquid from splashing out of the filling bottle and polluting the environment. The self-priming induction filling head 1 continues to descend, inserting the filling pipe 4 into the filling bottle mouth. At the same time, the telescopic pipe 5 retracts into the telescopic cavity 104, compressing the spring 106. The spring 106 pushes the telescopic pipe 5, thereby pressing the annular rubber seal 501 against the filling bottle mouth. The air pressure sensor 102 detects the air pressure inside the self-priming cavity 101. The vacuum pump 2 sucks the gas inside the self-priming cavity 101 through the L-shaped suction pipe 201, creating a negative pressure inside the self-priming cavity 101. Due to the negative pressure, the raw material in the storage tank enters the telescopic cavity 104 through the feeding pipe 3. The U-shaped baffle 202 shields the orifice of the L-shaped suction pipe 201 to prevent the liquid from entering the L-shaped suction pipe 201. The liquid inside the self-priming cavity 101 is filled into the filling bottle through the filling pipe 4, realizing filling.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be encompassed within the present utility model.
