[0028] Further, the discharging mechanism further comprises a blocking block 57 fixed at the end of the slide rod 55 away from the arc-shaped block 56, and the blocking block 57 is slidably arranged in the elastic tube 53, and a spring 58 is sleeved on the outer surface of the slide rod 55, and the two ends of the spring 58 are fixedly connected with the arc-shaped block 56 and the rectangular block 54 respectively.

[0029] Further, the discharging mechanism further comprises a cam 59 fixed on the outer surface of the stirring rod 4, and the cam 59 corresponds to the position of the arc-shaped block 56.

[0030] Firstly, the mixing barrel 2 is correctly clamped on the rack 1, and the raw materials of the silicone glue which need to be mixed with the silicone oil are poured into the mixing barrel 2 according to the specified amount, and then it is checked whether the oil storage tank 51 is clean, and then a proper amount of silicone oil is injected into the oil storage tank 51.

[0031] The motor is started, and the motor drives the stirring rod 4 to start high-speed rotation to stir the silicone glue in the mixing barrel 2, and at the same time, the cam 59 on the stirring rod 4 rotates with the stirring rod 4, and when the protruding part of the cam 59 contacts the arc-shaped block 56, the arc-shaped block 56 is pushed to move away from the stirring rod 4, and the slide rod 55 slides on the rectangular block 54, and at this time, the spring 58 is compressed, and the blocking block 57 at the other end of the slide rod 55 moves upward in the elastic tube 53 to open the passage of the elastic tube 53, and the silicone oil in the oil storage tank 51 flows into the mixing barrel 2 through the oil pipe 52 and the elastic tube 53 under the action of gravity to start mixing with the silicone glue being stirred.

[0032] With the continuous rotation of the cam 59, when the protruding part of the cam 59 moves away from the arc-shaped block 56, the spring 58 restores the deformation to push the arc-shaped block 56 to move towards the stirring rod 4, and the slide rod 55 drives the blocking block 57 to move downward to reseal the elastic tube 53, so that during the continuous rotation of the stirring rod 4, the cam 59 periodically acts on the arc-shaped block 56 to make the blocking block 57 intermittently open and close the elastic tube 53, and the silicone oil is gradually added to the silicone glue in the form of small doses and multiple batches, and during the whole stirring and adding process, the mixing state of the silicone glue and the silicone oil is continuously observed, and the rotating speed of the motor is appropriately adjusted according to the actual situation to control the stirring intensity and the adding frequency of the silicone oil, so as to ensure that the silicone oil is uniformly dispersed in the silicone glue, until the set stirring time and the silicone oil adding amount are reached, and the uniform mixing operation of the silicone glue and the silicone oil is completed.
