They can handle one-component and two-component materials with or without fillers, from low viscosity to high viscosity. The mechanical potting volume ensures consistent injection volume. When using two-component materials, a stable mixing ratio is maintained by discharging the materials in the two cylinders into a common mixing tube at the same time. However, the current piston type glue injection head has a discontinuous and unstable injection process, low efficiency, high coating accuracy, and a complex structure, which is not easy to maintain and operate. Summary of the invention

[0006] The top of the first fixing block is connected to the second fixing block, the top of the second fixing block is connected to a fixing frame, and a sliding block is slidably connected inside the fixing frame;

[0007] The bottom of the sliding block is connected to a push plate via a connecting rod, and the push plate is slidably connected in the first fixed block;

[0008] The bottom of the first fixing block is also connected to a glue outlet head which is in communication therewith.

[0009] Preferably, a stepper motor is connected to the top outer wall of the fixing frame, a lead screw is connected to the output end of the stepper motor, and the slider is threadedly connected to the lead screw.

[0010] Preferably, the first fixed block and the second fixed block are both provided with interconnected circular grooves, the push plate is slidably connected in the circular groove, the inner wall of the circular groove is provided with a fixed plate, and the lead screw is rotatably connected to the top outer wall of the fixed plate.

[0011] Preferably, a water inlet connected to the connecting pipe is provided on the side wall of the first fixing block, a one-way valve is provided in the water inlet, and an arc baffle matching with the water inlet is provided on the outer wall of the push plate.

[0012] Preferably, a triangular block is provided on the inner wall of the first fixed block, and through holes are provided on the triangular block and the first fixed block. A slide plate is slidably connected in the through hole, a V-shaped plate is connected to the top of the slide plate, and a V-shaped groove matching the V-shaped plate is provided at the bottom of the push plate.

[0013] Preferably, an elastic member is connected between the V-shaped plate and the top outer wall of the triangular block.

[0014] Preferably, the top outer wall of the fixed frame is also connected to a support plate, the top outer wall of the support plate is connected to a cylinder via bolts, the output end of the cylinder is connected to the piston body via a push rod, a slide groove matching the push rod is provided on the support plate, and the number of the rubber hoses is two.

[0015] Preferably, the inner wall of the glue outlet head is provided with two pipes, and the outer wall of the glue outlet head is provided with a threaded block, and the outer wall of the threaded block is threadedly connected with a glue mixing head.

[0016] Compared with the prior art, the present invention provides a piston-type metering glue injection head, which has the following beneficial effects:

[0017] 1. When using the piston-type metering glue injection head, different glues are respectively injected into the two rubber hoses, and then the cylinder is connected to the support plate, and the push rod is connected to the slide groove at the same time, so that the piston body is slidably connected to the upper rubber hose, and the cylinder is started. Then the glue in the rubber hose will flow through the connecting pipe to the circular groove on the first fixed block, and then the stepper motor is started to drive the push plate to move downward, so that the push plate presses the glue, and the slide plate is slidably connected in the circular groove, so that the two glues will not be mixed in advance, and then the glue will enter the pipe on the glue outlet head, and the glue mixing head can be threadedly connected on the threaded block, so that the two glues can be mixed and flow out, which is convenient to use.

[0018] 2. The piston-type metering glue injection head starts the stepper motor, which drives the lead screw to rotate, thereby driving the slider threadedly connected thereto to move downward. Since the slider is slidably connected in the fixed frame, the groove in the fixed frame is set to be square, so that the slider will not rotate with the lead screw, thereby making it more stable. When the slider moves, it will drive the push plate to move downward through the connecting rod, so that the push plate squeezes the glue, and the one-way valve will prevent it from flowing back into the connecting pipe, so that it can easily flow out from the glue outlet head. When the push plate moves, it will drive the arc baffle to move, so that it blocks the water inlet, quantifies the extruded glue, and prevents the glue from flowing to the top of the push plate. At the same time, the V-shaped groove will press the V-shaped plate, so that it drives the slide plate to slide in the through hole, which is convenient for the movement of the push plate, and the triangular block will prevent the glue from flowing into the through hole.

[0019] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The glue injection process of the present invention is completely continuous and stable, and the glue output is stable, the efficiency is high, the coating accuracy is high, the structure is simple, and it is easy to maintain and operate.
