Problems solved by technology

In the process of assembling the components back to the two-component metering valve after cleaning or replacing the components, the piston spring will generate a reverse force during the assembly process, often resulting in the need for two people to assemble the two-component metering valve. The situation that the metering valve is assembled is completed, causing considerable inconvenience
Therefore, the disadvantage of the existing two-component metering valve is that the sealing ring pad is easy to be worn, and the glue dispensing speed is slow, and the demand for glue with different proportions cannot be realized, resulting in low efficiency during construction.

Embodiment 1

[0030] Such as figure 1 , figure 2 , image 3 As shown, a valve body includes an upper valve body 1, a lower valve body 3, and a material inlet and outlet control device 6. The upper valve body 1 and the lower valve body 3 are connected by a fixing device, and the upper valve body 1 includes an upper valve body. Shell and the driving device 18 arranged on the upper valve body;

[0031] The lower valve body 3 is arranged below the upper valve body 1, and at least one inlet and outlet control device 6 is arranged on the lower valve body 3,

[0032] Between the upper valve body 1 and the lower valve body 3, a transmission device 11 and a material feeding and discharging actuator are arranged,

[0033] The driving device is connected to the upper part of the material in and out actuator through the transmission device, the lower part of the material in and out of the actuator is connected to the first end of all the living rods, and the second end of each living rod is connect...

Embodiment 2

[0045] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, the driving device arranged above the upper valve body 1 is a pneumatic driving device. When the driving mechanism in the upper valve body shell is a pneumatic driving device 1A; The head of the body is provided with an adjustment knob 41, and a cylinder and a transmission shaft are arranged in the upper valve body. The head of the transmission shaft is a cross-shaped head, and the cross-shaped head is arranged in the cylinder. The cross-shaped head is connected to the adjustment knob, the middle part of the transmission shaft is arranged in the transmission shaft channel, and the tail of the transmission shaft is connected to the connecting plate through a connecting device;

[0046] The cross-shaped head is arranged in the cylinder 62A, the cross-shaped head is connected with the adjustment knob 41, the middle part of the transmission shaft 48A is arranged in the first channel 20A, and the transmission ...

Embodiment 3

[0065] Such as figure 1 , figure 2 , image 3 , Figure 4 As shown, on the basis of the above-mentioned implementation examples, the two-component metering valve is usually used in conjunction with a glue dispenser or a desktop robot or manipulator.

Abstract

The invention relates to a two-component metering valve. A valve body comprises an upper valve body, a lower valve body and a metering device; the upper valve body comprises an upper valve body shell and a driving device arranged in the upper valve body shell; a cavity is formed in the upper part of the lower valve body; at least two piston channels are parallelly formed at the bottom in the cavity; a glue outlet is formed on the tail part of each piston channel; a piston is arranged in the middle of each piston channel; at least one part of the sealed end of each piston is arranged in each corresponding glue outlet; at least one sealing device is arranged between each piston and each corresponding piston channel; the top ends of the parallelly arranged pistons are fixed on the same connecting plate; a connecting device is connected with the driving device through at least one transmission device; and the at least one transmission device is arranged in a transmission device channel formed between the upper valve body and the lower valve body. The glue dispensing two-component metering valve dispenses glue quickly and accurately, breaks the glue completely, and has a sealing structure which is difficult to damage.

Description

technical field [0001] The present invention relates to fluid control equipment, in particular to a two-component metering valve. Background technique [0002] Nowadays, the application of two-component metering valves for gluing components in the packaging process is quite common. Traditionally, the structure of two-component metering valves usually uses four base screws and four upper cover screws to connect one cover and one piston. A device formed by combining structural components such as a spring, a piston, a body, a needle valve, a valve seat body, and a tail seat. When the two-component metering valve enters a glue solution, and the needle valve is driven by the piston, the glue solution can be pushed out by the needle valve to achieve the purpose of dispensing, and the multi-hole two-component metering The valve device is a two-component metering valve structure that is bolted together by screws. In the process of dispensing glue in the two-component metering valv...
