Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing machines, in particular to a double-liquid proportional valve for glue dispensing machines. Background Art

[0002] Glue dispensing machine, also known as glue coating machine, glue dripping machine, glue spraying machine, glue filling machine, etc., is an automated machine that specifically controls fluids and drips and applies fluids to the surface or inside of products.

[0003] The proportional valve is an indispensable structure of the dispensing machine. It mainly plays the role of providing glue liquid to the dispensing machine. The glue liquid used in the current dispensing machine is usually formed by mixing two kinds of glue liquids A and B. In the existing technology, the two kinds of glue liquids A and B are supplied by their own metering pumps. After the metering pumps accurately mix the two kinds of glue liquids A and B, they are transported to the A and B glue valves through pipelines. However, in the existing proportional valves, the distance between the metering pumps and the glue valves used is generally large, which leads to a long pipeline for transporting glue liquid. When the actual demand is that A The ratio of glue liquid A is much larger than that of glue liquid B. If the pipeline for conveying glue liquid B is very long and the proportion of glue liquid B is small, more glue liquid B will be lost in the longer pipeline, causing the problem of glue liquid B pipeline loss, thereby reducing the ratio accuracy. Therefore, we proposed a dual-liquid proportional valve for dispensing machines. The proportional valve can mix glue liquids A and B according to the ratio, and the proportional valve has a compact structure. The metering pump with a small proportion is installed on the confluence power seat, which greatly reduces the pipeline loss, thereby ensuring the ratio accuracy. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a dual-liquid proportional valve for a dispensing machine, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a dual-liquid proportional valve for a dispensing machine, comprising:

[0006] A confluence power seat, which is a supporting base for the dual-liquid proportional valve;

[0007] A glue valve, which is obliquely installed on one side of the converging power seat and can provide A glue liquid into the converging power seat;

[0008] A B glue valve, which is obliquely installed on the other side of the converging power seat and can provide B glue liquid into the converging power seat;

[0009] A mixing tube, which is detachably connected to the glue outlet of the confluence power seat;

[0010] A stirring shaft is movably arranged inside the mixing tube, and the stirring shaft can rotate at a high speed inside the mixing tube to mix the A and B glue solutions.

[0011] Furthermore, the dispensing machine dual-liquid proportional valve also includes:

[0012] A driving motor 1 is installed on the upper part of the confluence power seat, and the driving motor 1 can drive the stirring shaft to rotate at a high speed and is connected to the stirring shaft through a transmission shaft.

[0013] Furthermore, the dispensing machine dual-liquid proportional valve also includes:

[0014] The liquid outlet joint is fixedly connected to the glue outlet of the converging power seat, and the mixing tube is sleeved on the outside of the liquid outlet joint, and the two are connected by a clamp sleeved on the outside of the mixing tube.

[0015] Furthermore, the dispensing machine dual-liquid proportional valve also includes:

[0016] The B glue metering pump is installed on the front side of the confluence power seat through a fixing block, and the B glue metering pump can provide B glue liquid to the B glue valve in a quantitative manner.

[0017] Furthermore, the B glue metering pump includes a metering pump body installed on a fixed block, the metering pump body is driven by a second driving motor, and a speed changer is installed in series between the second driving motor and the metering pump body.

[0018] Furthermore, the glue outlet at the bottom end of the metering pump body is connected to the glue inlet of the B glue valve through a B glue transfer tube.

[0019] Furthermore, the bottom end of the converging power seat has a glue outlet, and two inclined surfaces are symmetrically arranged at the bottom of the converging power seat, one serving as the installation base surface for the A glue valve, and the other serving as the installation base surface for the B glue valve. Glue inlet channels are reserved inside the two inclined surfaces, one corresponding to the A glue valve is the A glue channel, and the other corresponding to the B glue valve is the B glue channel. A sealing gasket 1 is arranged between the A glue channel and the glue outlet of the A glue valve, and a sealing gasket 2 is inserted into the B glue channel. A reserved hole is opened in the middle of the sealing gasket 2, and the glue outlet of the B glue valve is connected to a glue outlet extension tube, which is inserted in the B glue channel, and the end is connected to a glue outlet nozzle, which is inserted in the reserved hole.

[0020] Furthermore, an axial hole is opened in the middle of the converging power seat, and the axial hole, glue channel A and glue channel B all extend in the direction of the glue outlet. A shaft seal is installed inside the axial hole, and the transmission shaft is located in the shaft seal, and the transmission shaft and the shaft seal can rotate relative to each other.

[0021] Compared with the above-mentioned background technology, the dual-liquid proportional valve of the dispensing machine provided in the present application includes a converging power seat, A glue valve, B glue valve, a mixing tube, a stirring shaft and a driving motor. The A and B glue liquids are transported to the converging power seat through the A glue valve and the B glue valve, and then to the mixing tube. The driving motor then drives the stirring shaft to rotate at a high speed, thereby fully mixing the glue liquids in the mixing tube.

[0022] The utility model provides a dual-liquid proportional valve for a dispensing machine. Compared with the prior art, it has the following beneficial effects:

[0023] The dual-liquid proportional valve of the dispensing machine installs the B glue metering pump with a smaller amount on the confluence power seat, so the distance between the B glue metering pump and the B glue valve is greatly reduced, and it can be connected with a short and thin B glue adapter tube. In this way, after the B glue with a smaller amount is proportioned by the metering pump, the loss of glue in the pipeline will be very small because the pipeline is very short and thin, and finally the proportioning accuracy of B glue can be greatly improved.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0035] See also Figure 1-6 The utility model provides a technical solution: a dual-liquid proportional valve for a dispensing machine, comprising a confluence power seat 1, an A glue valve 2, a B glue valve 3, a driving motor 4, a liquid outlet joint 5, a mixing tube 6, a clamp 7, a stirring shaft 8, a B glue metering pump 9 and a B glue transfer tube 10, wherein the A glue valve 2 and the B glue valve 3 are respectively installed on both sides of the confluence power seat 1, and are both installed at an angle. The A glue and the B glue distributed by the A glue valve 2 and the B glue valve 3 will be introduced into the confluence power seat 1, and the confluence power seat 1 will then introduce the A glue and the B glue into the mixing tube 6. A stirring shaft 8 capable of high-speed rotation is provided in the mixing tube 6, and the stirring shaft 8 is driven by the driving motor 4. There is a stirring shaft 8 between the B glue metering pump 9 and the B glue valve 3. They are connected through the B glue transfer tube 10, so the B glue liquid of the B glue valve 3 comes from the B glue metering pump 9. Similarly, the A glue liquid of the A glue valve 2 comes from the corresponding A glue metering pump, but the A glue metering pump is not shown in the figure. When the dual-liquid proportional valve of the dispensing machine is working, the A glue metering pump and the B glue metering pump 9 are used to provide A glue and B glue with corresponding proportions to the A glue valve 2 and the B glue valve 3, and the A glue and B glue are introduced into the converging power seat 1 through the A glue valve 2 and the B glue valve 3, and then introduced into the mixing tube 6 by the converging power seat 1. The driving motor 4 drives the stirring shaft 8 to rotate at a high speed inside the mixing tube 6, so that the A glue and B glue with good proportions can be evenly and fully mixed together, and then discharged through the mixing tube 6.

[0036] In addition, the dual-liquid proportional valve of the dispensing machine installs the B glue metering pump 9 with a smaller amount on the confluence power seat 1, so the distance between the B glue metering pump 9 and the B glue valve 3 is greatly reduced, and it can be connected with a short and thin B glue adapter tube 10. In this way, after the B glue with a smaller amount is proportioned by the metering pump, the loss of glue liquid in the pipeline will be very small because the pipeline is very short and thin, and finally the proportioning accuracy of the B glue can be greatly improved.

[0039] Secondly, an axial hole 14 is also opened in the middle of the converging power seat 1. The glue channel A and the glue channel B of the axial hole 14 extend toward the glue outlet 11 and finally converge at the position of the glue outlet 11. A shaft seal 41 is installed inside the axial hole 14. The driving end of the driving motor 4 is connected to the stirring shaft 8 through a transmission shaft 42. The transmission shaft 42 is located in the shaft seal 41, and the transmission shaft 42 and the shaft seal 41 can rotate relative to each other.

[0040] Thirdly, in order to facilitate the connection between the glue outlet 11 and the mixing tube 6, a liquid outlet connector 5 is first fixedly connected to the glue outlet 11, and then the mixing tube 6 is sleeved on the outside of the liquid outlet connector 5, and then the clamp 7 is sleeved on the outside of the mixing tube 6. By disassembling and assembling the clamp 7, the mixing tube 6 can be quickly disassembled and assembled.

[0041] Fourthly, the B glue metering pump 9 includes a metering pump body 94 installed on the fixed block 91, the metering pump body 94 is driven by the driving motor 2 92, and a speed changer 93 is installed in series between the driving motor 2 92 and the metering pump body 94, and the glue outlet at the bottom end of the metering pump body 94 is connected to the glue inlet of the B glue valve 3 through the B glue transfer tube 10.
