Referring to fig. 2 to 4, in the present embodiment, the manual control dispenser includes: the device comprises a pressure container 1, a bracket 61, a two-component dispensing valve 4, a first pipeline 2, a second pipeline 3, a glue nozzle 5, a foot switch SB1, a sensor and a controller 9. The pressure vessel 1, the bracket 61, the sensor and the controller 9 are mounted on a substrate 6.

The pressure container 1 is used for containing the colloid, is provided with relief pressure valve 11 on the pressure container 1, and relief pressure valve 11 links to each other with total trachea 12 gas circuit, provides pressure gas to pressure container 1 inside, presses the colloid in the pressure container 1 to gluey mouth 5, realizes gluing to the product.

The bracket 61 is used for supporting the glue nozzle 5 and the glue dispensing valve.

The dispensing valve is a valve special for a dispensing machine and has two types of pneumatic and electric. The pneumatic dispensing valve is formed by connecting an air cylinder, a valve body and a material cylinder up and down, and the air cylinder and the valve body are separated by advanced sealing materials, so that the glue is prevented from invading the air cylinder. The material cylinder and the air cylinder are connected to the dispensing valve main body and ensure concentricity with the air cylinder. And the solenoid valve F is used for driving the air cylinder to move, so that the central rod is driven to move up and down, and the opening and closing effects on the glue are achieved by utilizing the up-and-down movement of the central rod. According to different ways of turning on and off, the method can be divided into: plunger type dispensing valve, ejector pin type dispensing valve, lifting type dispensing valve, spraying dispensing valve and spraying dispensing valve. The electric dispensing valve comprises a pump body and a driving part, and is simple to install along with the stator. And the stator and the rotor are structurally designed, so that the sealing performance is good. The rotor and the stator pair form a self-sealing structure and are easy to replace. The medium conveying function is realized through the directional rotation action of the rotor in the stator cavity. According to different channel numbers, the dispensing valve is divided into a single-component dispensing valve and a double-component dispensing valve. The two-component dispensing valve has two valve cores which can be closed/opened respectively, is also called an AB dispensing valve and is mainly used for AB dispensing machines.

In this embodiment, the dispensing valve is a pneumatic two-component dispensing valve 4. The two-component dispensing valve 4 is fixed on the bracket 61.

The two-component dispensing valve 4 is provided with two glue inlets and two glue outlets, wherein one glue inlet is communicated with the pressure container 1 through the first pipeline 2, and the other glue inlet is communicated with the pressure container 1 through the second pipeline 3.

One end of the glue nozzle 5 is connected with two glue outlets of the two-component glue dispensing valve 4, in other words, the glue discharged from the two glue outlets is discharged through the same glue nozzle 5.

The control logic is as follows: when the foot switch SB1 is stepped down and the photoelectric switch 8 detects that the glue nozzle 5 has a product, dispensing is started; otherwise, dispensing will not begin. Wherein, photoelectric switch 8 and controller 9's combination has constituted and has prevented the maloperation circuit, prevents that maloperation theory of operation is: the diffuse reflection photoelectric switch 8 identifies whether the glue nozzle 5 has a product, and if no product exists, the controller 9 locks the dispensing valve in a closed state, and the dispensing valve cannot be conducted even if the foot switch SB1 is depressed.

The diffuse reflection photoelectric switch 8 and the controller 9 constitute a dispensing stop control circuit for controlling the stop of dispensing. The control logic is as follows: and when the product leaves the glue nozzle 5, immediately controlling the glue dispensing valve to close and stopping dispensing.

It is thus clear that this embodiment adopts the inductor to trigger the automatic shutdown point and glues, as long as the product leaves jiao zui 5, can the automatic shutdown point and glue, does not need the trick cooperation, and easy operation is convenient, can effectively prevent that the trick cooperation from improper leads to leaking to glue and scarce glue. In addition, the dispensing is started by adopting the cooperation control of the foot switch SB1 and the sensor, so that the dispensing caused by the misoperation of the foot switch SB1 can be prevented.
