[0041] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0042] The core of the utility model provides a kind of filling system and strip packing machine of strip packing machine, can improve the filling efficiency of viscous liquid.

[0043] The specific embodiment one of the filling system of the strip packing machine provided by the utility model is as follows Figures 1 to 6 Including import module 3, buffer tank 1 and filling module 2.

[0044] Import module 3 is used to supply material (for example, liquid medicine) to buffer tank 1, clean liquid such as purified water, clean compressed gas, etc.It needs to be noted that, in the present embodiment, the use is illustrated by taking viscous liquid as material, specifically liquid medicine, but the type of material cannot be limited by this, for example, it can also be food or thin liquid.

[0045] Filling module 2 is used to receive the material discharged from buffer tank 1, and then supply to strip packing machine main body 8.As shown in Figure 2 Filling module 2 includes first filling pipe 21, pump body 22, second filling pipe 23, filling needle 24 and oscillator 25.

[0046] First filling pipe 21 is connected to the outlet of buffer tank 1, and first filling pipe 21 is a vertical first straight pipe.As the first straight pipe does not have a corner, the material does not need to turn during flow, which can improve the smoothness of material flow and has strong adaptability to various materials.Oscillator 25 is connected to first filling pipe 21.

[0047] Pump body 22 is connected to the outlet of first filling pipe 21.Specifically, first filling pipe 21 is connected directly below buffer tank 1, so that pump body 22 is located directly below first filling pipe 21 and buffer tank 1.The buffer tank is connected directly above and below the pump body 2, which can ensure the material loading amount.Pump body 22 is specifically a ceramic pump, which has excellent acid and alkali resistance and can resist the corrosion of various strong acids and strong bases to avoid rusting and cracking of pump body 22.

[0048] Second filling pipe 23 is connected to the outlet of pump body 22, which provides driving force through pump body 22.Filling needle 24 is connected to the outlet of second filling pipe 23.

[0049] The filling system is suitable for viscous liquid, when the buffer tank 1 discharges the material, the viscous liquid firstly flows through the vertical first filling pipeline 21, under the gravity and the oscillation of the oscillator 25, and then flows through the second filling pipeline 23 to the filling needle 24 under the driving of the pump body 22, and the viscous liquid is filled through the filling needle 24, so that the filling efficiency of the viscous liquid is high, and the production efficiency of the strip packaging machine is improved.

[0050] As shown in Figure 2 , Figure 5 and Figure 6 , the oscillator 25 oscillates the first filling pipeline 21, so that the liquid medicine cannot flow from the buffer tank 1 to the inlet of the pump body 22 in time due to the too viscous liquid, thereby affecting the filling amount. The oscillator 25 is a high-frequency oscillator.

[0051] Specifically, a plurality of first filling pipelines 21 are arranged, and each first filling pipeline 21 is connected with an oscillator 25 on the side surface. The oscillator 25 is arranged on the oscillation support 251, and the oscillation support 251 supports the oscillator 25 at a proper height, which can be clamped, clamped, or screwed.

[0052] Specifically, at least two oscillators 25 are arranged on one oscillation support 251. As shown in Figure 2 , the bottom of the oscillation support 251 is fixed to the top of the strip packaging machine body 8, which can be screwed, and the top of the oscillation support 251 is provided with the oscillators 25, which can be connected with two oscillators 25.

[0053] For viscous liquid material, the length of the first filling pipeline 21 and the second filling pipeline 23 needs to be as short as possible, the shape needs to be as straight as possible, and the inner diameter needs to be as large as possible to ensure the flow rate. Based on this, in the second filling pipeline 23, as shown in Figure 2 , the second filling pipeline 23 includes a second straight pipeline 231 and a filling hose 232 connected between the outlet of the second straight pipeline 231 and the filling needle 24, and the inlet of the second straight pipeline 231 is connected to the outlet of the pump body 22.

[0054] At this time, the second straight pipeline 231 does not have a corner, and the material does not need to turn during the flow process, which can improve the smoothness of the material flow. The second straight pipeline 231 and the filling needle 24 are connected by the filling hose 232, which can reduce the assembly difficulty of the pipeline between the second straight pipeline 231 and the filling needle 24.

[0055] The second straight pipe 231 is horizontally placed, and the first straight pipe and the second straight pipe are arranged in an L shape. In addition, the first straight pipe and the second straight pipe 231 can also be an integral round pipe with the same diameter everywhere, or a square pipe, etc. Of course, in other embodiments, the second straight pipe 231 can also adopt an arc-shaped pipe, an elbow pipe, etc.

[0056] It should be noted that the filling hose 232 should be selected from the harder materials in the hose, and should be adapted to the type of material to ensure that the material does not cause the filling hose 232 to expand and deform, damage, and inaccurate filling amount during the filling process.

[0057] When the to-be-filled liquid medicine is viscous, the liquid medicine may seal air in the liquid medicine after entering the buffer tank 1, and there is a problem of inaccurate filling amount. To solve this problem, as shown in Figure 1 The stirring device 11, the water bath heating device 13, and the electric heating device 12 are provided on the buffer tank 1 to ensure the smoothness of the material flow and to discharge air. Only one or two of them can also be provided.

[0058] The stirring device 11 is a stirring motor extending into the buffer tank 1, which is operated in real time to ensure that the material in the buffer tank 1 is stirred in real time. Through the stirring of the stirring device 11, the gas in the liquid medicine can be discharged, and the flowability of the liquid medicine is increased.

[0059] The water bath heating device 13 can include a water layer provided outside the buffer tank 1, as shown in Figure 1 The water layer can wrap the side and bottom of the buffer tank 1, and has a hot water inlet 131 butted to the top of the water layer and a hot water outlet 132 butted to the bottom of the water layer. The hot water enters the water layer through the hot water inlet 131 and is discharged from the hot water outlet 132. The hot water can be directly used as the existing hot water, for example, the hot water in other processes in the production process.

[0060] The electric heating device 12 can be provided at the bottom of the buffer tank 1 and started as needed, for example, started at a fixed time, or the starting time and temperature are controlled according to the flow speed of the material in the filling module 2, or started when there is no hot water but there is a heating demand.

[0061] Through the heating function of the water bath heating device 13 and the electric heating device 12, the viscosity of the viscous liquid medicine can be reduced due to the increase in temperature, and the flowability of the liquid medicine is increased.

[0062] In addition, the buffer tank 1 is also provided with a pressurizing port for pressurizing the buffer tank 1. The buffer tank 1 is connected to a gas pump to increase the filling pressure of the liquid medicine.

[0063] Specifically, in the pressurization control, the detection value of the liquid level sensor 17 of the buffer tank 1 can be combined to control the pressurization process. The liquid level sensor 17 can adopt a laser detection mode. When the liquid level sensor 17 in the buffer tank 1 detects that the liquid level of the material in the buffer tank 1 rises to the set liquid level, the buffer tank 1 is pressurized until the liquid level drops to a certain distance below the set liquid level, ensuring that the material moves downward, and avoiding excessive resistance caused by excessive amount and viscosity of the stored material, and ensuring that the pressure is provided to the material in time to facilitate the movement of the material.

[0064] In addition, the buffer tank 1 has a plurality of discharge ports 14, for example, 6. Each discharge port 14 of the buffer tank 1 is connected with a different filling module 2. By selecting a buffer tank 1 with multiple discharge ports 14, the buffer tank 1 can directly supply material to multiple second filling pipelines 23, for example, Figure 6 As shown, the bottom of the buffer tank 1 is provided with 6 discharge ports 14, and 6 filling modules 2 are connected to the discharge ports 14 one by one.

[0065] Among them, each filling module 2 can be the same, which can ensure that the amount of medicine in each filling module 2 is basically the same. At this time, the material discharged from the buffer tank 1 directly reaches the inlet of the pump body 22 through the first filling pipeline 21, and is then discharged to the second filling pipeline 23 and the filling needle 24.

[0066] Among them, the buffer tank 1 can be a groove type buffer tank with multiple discharge ports 14. In other embodiments, a circular buffer tank can also be used.

[0067] At this time, compared with the buffer tank 1 with one discharge port 14, it is beneficial to shorten the liquid stroke of the filling module 2. For the buffer tank 1 with one discharge port 14, a main discharge pipe needs to be connected to the buffer tank 1, and multiple branch pipes need to be connected to the outlet of the main discharge pipe for liquid distribution to supply material to different filling modules 2. Compared with the buffer tank 1 directly connected to multiple filling modules 2 and supplying material to the filling modules 2, when the straight-line distance between the discharge port 14 and the filling needle 24 is the same, the liquid stroke is longer in the former way due to the need for liquid distribution. The way adopted in the present embodiment can more flexibly set the liquid stroke and can set a smaller stroke, which is more suitable for the filling of viscous liquids with large flow resistance and slow flow rate, and can reduce the loss of filling amount and filling resistance caused by the adhesion of the material to the pipeline.

[0068] Among them, the filling system further includes an inlet module 3, as shown in Figure 1 and Figure 4As shown, the inlet module 3 includes a first valve V1, a second valve V2, a feed pipe 31, and a cleaning pipe 32. The first valve V1 and the second valve V2 can specifically be pneumatic valves. The inlet module 3 can be connected to the chuck opening of the buffer tank lid. The inlet module 3 is located above the buffer tank 1 to clean the strip packaging machine from a height.

[0069] The first valve V1 is a T-type valve, including a side inlet 91, a side outlet 92, and a bottom outlet 93, capable of controlling whether the side inlet 91 is connected to the side outlet 92 or the bottom outlet 93. Optionally, with this T-type valve, the side inlet 91 and the bottom outlet 93 can remain connected, and the opening and closing of the T-type valve can control the on / off state of the side inlet 91 and the side outlet 92. Using a T-type valve can reduce blind-end pipelines during filling and prevent incomplete cleaning of the filling pipeline.

[0070] The cleaning pipe 32 connects the side outlet 92 and the cleaning port 15 of the buffer tank 1. The cleaning solution can enter the buffer tank 1 through the side inlet 91 and side outlet 92 of the first valve V1 and the cleaning pipe 32 to clean the buffer tank 1. Specifically, the cleaning pipe 32 is used for the cleaning solution to enter the filling and cleaning related pipelines, and is connected to the corresponding clamping port of the buffer tank lid. It is used to clean the medicine filling tank and medicine filling pipelines. The cleaning solution is mostly purified water.

[0071] The feed pipe 31 connects the bottom outlet 93 and the feed inlet of the buffer tank 1. The second valve V2 is installed on the feed pipe 31 to control its opening and closing. Material can enter the buffer tank 1 through the side inlet 91 of the first valve V1, the bottom outlet 93, and the feed pipe 31, thus feeding the buffer tank 1. The second valve V2 can control the material flow on and off the feed pipe 31, improving the accuracy of the feed rate control.

[0072] Among them, the feed pipe 31 is a vertically arranged third straight pipe to ensure the smooth downward flow of materials.

[0073] In addition, such as Figure 1 As shown, the import module 3 also includes a spray ball 33, which is located at the cleaning port to improve the cleaning effect on the buffer tank 1.

[0074] The imported module 3 can be used to circulate purified water and compressed air during cleaning after production. The purified water is used to clean the inlet pipe section, and the compressed air is used to purge and clean the imported module 3. In addition, the cleaning pipe 32 can also be used as a pressurization port for compressed air to pressurize the buffer tank 1 during filling production. If the liquid is too viscous and affects filling production, the flow rate of the liquid can be increased by pressurizing the buffer tank 1 to meet production requirements.

[0075] Of course, in addition to using the cleaning structure in the filling system, manual cleaning can also be combined to ensure cleaning quality.

[0076] In the cleaning process, in order to realize the pollution, as shown in Figure 1 , Figure 2 and Figure 4 The buffer tank 1 is connected with the first drain pipe 4, the third valve V3 is arranged on the first drain pipe 4, the water collecting groove 5 is arranged below the filling needle 24, the outlet of the water collecting groove 5 and the outlet of the first drain pipe 4 are connected to the second drain pipe 6, and the fourth valve V4 is arranged on the second drain pipe 6. In addition, the electric conductivity detector 61 can also be arranged on the second drain pipe 6. After cleaning, the cleaning liquid in the second drain pipe 6 can be drained to the floor drain. The third valve V3 and the fourth valve V4 can be pneumatic valves.

[0077] The filling system in the embodiment can provide the filling and cleaning functions of viscous liquid medicine and the like for a bagging machine, has stable filling, high cleaning degree, simple structure, high integration degree and small occupied space.

The purpose of this step is to rotate and wash the buffer tank 1 through the spray ball 33 of the buffer tank 1, and then the sewage is discharged from the buffer tank 1.

[0082] III. Filling needle 24 cleaning: after production is completed and the buffer tank 1 is cleaned, this process is performed, that is: purified water - first valve V1 (closed) - second valve V2 (opened) - buffer tank 1 - pump body 22 - filling needle 24 - water collecting groove 5 - fourth valve V4 (opened) - floor drain. At this time, the cleaning medium is purified water, and the terminal filling needle 24, guide pipe and other structures are cleaned. At the same time, the cleaning liquid is collected by the water collecting groove 5, the fourth valve V4 (opened) is opened, and is discharged to the floor drain.
