One side of the fixed plate 11 is opposite to the other side of the fixed plate 11; the second syringe 142 is used for storing the glue B, and the second syringe 142 is communicated with the second glue inlet channel 143, so that the glue B enters the second glue inlet channel 143 from the syringe; the third one-way valve 171 is that the glue B can only flow along the glue inlet, but the medium at the glue outlet can not flow back; the first cavity 133 temporarily stores the B-glue flowing in through the first glue inlet channel 132. In the production process, air pressure is input to the second needle cylinder 142, the air pressure pushes the glue B stored in the second needle cylinder 142 to move towards the second glue inlet channel 143, and as the air pressure is continuously input to the second needle cylinder 142, the pressure for pushing the glue B to move is greater than the compression force of the spring 1343 of the third one-way valve 171 along with the time, so that the glue B pushes the third one-way valve 171 open, and the glue second inlet channel 143 is opened, so that the glue second inlet channel 143 is communicated with the second cavity 144, and therefore the glue B can enter the second cavity 144 through the glue second inlet channel 143.
The driving assembly 15 is disposed at the other end of the fixed plate 11 and movably disposed in the first cavity 133, where one end of the fixed plate 11 and the other end of the fixed plate 11 are opposite ends.
The driving assembly 15 includes a first plunger rod 153 and a second plunger rod 154, wherein one end of the first plunger rod 153 passes through the first cavity 133, one end of the first plunger rod 153 is inserted into and movably disposed in the first cavity 133, and a sidewall of the first plunger rod 153 abuts against an inner sidewall of the first cavity 133 to prevent the glue a from overflowing, and the first plunger rod 153 is used for pushing the glue a out. One end of the second plunger rod 154 is inserted into and movably disposed in the second cavity 144, and a sidewall of the second plunger rod 154 abuts against an inner sidewall of the second cavity 144 to prevent the B glue from overflowing.
The first glue outlet mechanism 16 comprises a first glue outlet channel 161 and a second one-way valve 162, the first glue outlet channel 161 is arranged on the valve body 12 and is communicated with the first cavity 133, and the second one-way valve 162 is arranged on the first glue outlet channel 161; in the production process, the driving assembly 15 drives the first plunger rod 153 to move downwards, so that when the first plunger rod 153 drives the adhesive a to move downwards to the second one-way valve 162, the adhesive a pushes the second one-way valve 162 open due to the pushing force of the driving assembly 15 being greater than the compression amount of the spring 1343 of the second one-way valve 162, thereby opening the first adhesive outlet channel 161, and further enabling the first cavity 133 to be communicated with the first adhesive outlet channel 161, so that the adhesive a can flow to the first adhesive outlet channel 161.
The second glue discharging mechanism 17 and the first glue discharging mechanism 16 are arranged in a mirror image mode, the second glue discharging mechanism 17 comprises a second glue discharging channel and a third one-way valve 171, the second glue discharging channel is arranged on the valve body 12 and is communicated with the second cavity 144, the third one-way valve 171 is arranged on the second glue discharging channel, the two-component glue dispensing device 10 further comprises a second plunger rod 154, the second plunger rod 154 and the first plunger rod 153 are arranged in a mirror image mode, one end of the second plunger rod 154 penetrates through the first cavity 133, and the other end of the second plunger rod 154 is movably arranged in the second cavity 144 and abuts against the inner side wall of the second cavity 144; in the production process, the driving assembly 15 drives the second plunger rod 154 to move downwards, so that when the second plunger rod 154 drives the B glue to move downwards to the third one-way valve 171, the B glue pushes the third one-way valve 171 open due to the driving force of the driving assembly 15 being greater than the compression amount of the spring 1343 of the third one-way valve 171, thereby opening the second glue outlet channel, and further enabling the second cavity 144 to be communicated with the second glue outlet channel, so that the B glue can flow to the second glue outlet channel.
The mixing tube 18 is disposed at an end of the valve body 12 far away from the first cavity 133, the glue outlet of the first glue outlet channel 161 and the glue outlet of the second glue outlet channel are all communicated with the glue inlet of the mixing tube 18, during production, glue a and glue B respectively flow to the glue inlet of the mixing tube 18 through the first glue outlet channel 161 and the second glue outlet channel, and glue a and glue B are mixed in the mixing tube 18.
The two-component dispensing device 10 has two processes of filling and dispensing, wherein, as shown in fig. 3, the filling process is to simultaneously introduce air pressure into the first syringe 131 and the second syringe 142, the first check valve 134 and the fourth check valve 141 are opened, and the glue a and the glue B are not enough to open the second check valve 162 and the third check valve 171, so that the glue a and the glue B enter the first cavity 133 and the second cavity 144 respectively, because the compression amount of the spring 1343 of the second check valve 162 and the compression amount of the spring 1343 of the third check valve 171 are larger than the compression amount of the spring 1343 of the first check valve 134 and the compression amount of the spring 1343 of the fourth check valve 141; the first plunger rod 153 moves upwards under the action of the A glue, the first plunger rod 153 moves to the upper limit of the push rod 152, and the first cavity 133 is filled with the A glue; the second plunger rod 154 moves upwards under the action of the glue B, the second plunger rod 154 moves to the upper limit of the push rod 152, the glue B is filled in the second cavity 144, the filling process only needs to ensure that the air pressure introduced is larger than the compression amount of the spring 1343 of the first one-way valve 134 and the compression amount of the spring 1343 of the fourth one-way valve 141, the filling of glue A and glue B can be realized, the complex structural design of the rotary valve and the precision matching problem during rotation are avoided, or the complex structural design of the double-screw metering type is avoided, so that the structure of the double-component dispensing device 10 is simpler and more reliable, and the cleaning and the maintenance of the double-component dispensing device are more convenient due to the simple structure.
As shown in fig. 4, the dispensing process: when the first cavity 133 and the second cavity 144 are respectively filled with the glue a and the glue B, the first syringe 131 and the second syringe 142 stop introducing air pressure, the first check valve 134 and the fourth check valve 141 are closed, the driving assembly 15 pushes the first plunger rod 153 and the second plunger rod 154 downwards, and the second check valve 162 and the third check valve 171 are opened; glue A and glue B enter a mixing tube 18 for mixing; according to the required dispensing amount, the driving assembly 15 pushes the first plunger rod 153 and the second plunger rod 154 to displace for a certain distance, and the dispensing can be quantitatively performed by v=s×h, V is the volume of the mixing tube 18, S is the bottom area of the mixing tube 18, and H is the height of the mixing tube 18.
