Description

Technical Field

[0001] The invention relates to a glue supply system, in particular to a large-flow automatic proportioning and mixing glue supply system and equipment. Background Art

[0002] Most of the dispensing, filling and scraping industries on the market use plunger pumps to transfer and transport materials. The instantaneous pressure is often high and the pressure is unstable. It is necessary to add precision accessories such as pressure regulating valves and metering valves, resulting in very high costs. Secondly, due to the small flow rate, a PE mixing tube at the end is used for mixing. The PE mixing tube is disposable.

[0003] The plunger metering pump has a maximum single injection volume due to the limitation of the cavity, and a single metering pump will form an intermittent time. There are some disadvantages in terms of complex structure, sealing problems, noise and vibration, high anti-pollution requirements and high cost.

[0004] The existing glue mixing systems are mostly operated manually or semi-automatically, which are inefficient. It is difficult to ensure the accuracy and consistency of the glue mixing ratio during manual operation, resulting in unstable product quality and even a large number of bubbles. In addition, when handling large flows of glue, manual or semi-automatic systems require high labor intensity for operators, low safety, and are difficult to adapt to rapidly changing production needs.

[0005] When dealing with glues of different viscosities and mixing ratios, the existing glue mixing system has cumbersome adjustment and cleaning processes, which affects production efficiency and product quality. At the same time, due to the lack of intelligent control, the system is difficult to adapt to changes in different material properties and process requirements, limiting its use in complex application scenarios.

[0006] After long-term operation, some mixing systems will have inaccurate mixing ratios due to wear and aging, affecting product quality and production efficiency. At the same time, the maintenance and replacement costs of these systems are high, increasing the operating costs of enterprises. Summary of the invention

[0007] In response to the above technical problems, the present invention proposes a large-flow automatic proportioning glue mixing and supplying system and equipment. The glue mixing and supplying system can achieve precise proportioning control, thereby obtaining continuous and stable high-pressure output without the need for expensive pressure-stabilizing valves, which not only significantly reduces the long-term use cost, but also greatly simplifies maintenance work.

After the intersection, the fourth straight pipe section of the second rubber supply hose is passed through the second straight pipe section on the first rubber supply hose until the pipe opening of the fourth straight pipe section is not lower than the pipe opening position of the second straight pipe section of the first rubber supply hose.

[0011] The first glue supply pipe is provided with a first flow meter for detecting the real-time glue supply amount in the first glue supply pipe; A second flow meter is installed on the second glue supply pipe, which is used to detect the real-time glue supply amount in the second glue supply pipe; The first flow meter and the second flow meter are both connected to the signal input terminal of the control module.

[0013] The mixing tube includes a plurality of mixing tube units, and the plurality of mixing tube units are axially connected through a fifth tube connector.

[0014] The first pipe connector, the second pipe connector, the third pipe connector, the fourth pipe connector and the fifth pipe connector are all quick-release clamps.

[0015] The mixing tube unit is a stainless steel tube SX type mixer.

Beneficial Effects

[0018] First, the present invention changes the traditional post-placement of the mixing tube into a pre-placement, and changes the traditional PE material SK type mixer to a larger stainless steel tube SX type mixer. This effectively solves the problem of insufficient flow due to a single glue outlet requiring a group of pumps, and the problem of uneven pressure or uneven mixing caused by a group of pumps equipped with three mixing tubes.

At the same time, when the equipment is shut down, the glue coating parts and the mixed glue in the pipeline can be disassembled for manual re-coating operations. When the equipment cannot be used normally due to site restrictions, the glue coating parts can be quickly disassembled to become a material extraction nozzle for direct manual material extraction, thereby reducing the labor intensity of workers to the greatest extent and ensuring that the equipment will not become useless due to site restrictions.

[0020] Third, the mixing valve designed by the present invention extends the small tube to the mixing tube joint, so that the mixing of the two-component sealant starts from the mixing tube, which effectively reduces the cleaning burden and reduces the cost. In addition, a flow meter is added inside the mixing valve to monitor the flow in real time and feed the data back to the controller, realizing the precise control of the automatic proportioning of the sealant.

[0021] Fourthly, the present invention proposes a one-to-four-pipe node, which changes the right-angle design into an obtuse-angle design, and adds a manual ball valve at each outlet to facilitate flow control. BRIEF DESCRIPTION OF THE DRAWINGS

It realizes the demand that a single group of pumps and a mixing tube can supply multiple glue outlets. Example
