In order to achieve a sealing effect, at least two layers of skeleton oil seals 161 are provided in the glue injection holes 16. An O-ring 5 is pressed outward from the top of the glue injection holes 16. In addition, the skeleton oil seals 161 are T-shaped skeleton oil seals and are arranged in parallel. An exhaust joint 17 is provided at the bottom of the vacuum box 1. For details, see Figure 5 and 6 The top cover of the air extraction joint 17 is provided with a protective cover 4, and the bottom of the air extraction joint 17 is pressed down with an O-ring 5 to enhance the sealing effect;

[0040] Working principle: When the utility model is in use, the opening of the feeding door is opened by the pushing assembly. After the material is fed in, the lifting cylinder in the pushing assembly drives the feeding door to move upward along the slide. Unlike the prior art, the bottom of the lifting cylinder is hinged with a base, that is, even if the base is fixedly mounted on the machine platform, the lifting cylinder can effectively seal the opening along the direction of the slide. Even if there is a machining inclination in the direction of the opening, it can be effectively closed, unlike the prior art which can only go straight up and down, resulting in insufficient tightness when closed. It should be noted that the opening is set inward. There is a sealing ring to cooperate with the sealing effect after the feed door is closed. When the feed door and the discharge door are closed in the same way, air is pumped outward through the vacuum joint to make the inside of the vacuum box reach a vacuum state; then a dispensing device (not shown in the figure) is installed on the glue filling hole, and inserted inward to extend into the vacuum box to perform dispensing. The dispensing situation can be observed through the observation window. It should be noted that sealing rings or O-rings are provided at the positions of the observation window and the operating door to achieve a sealing effect, effectively ensuring that the dispensing process is in a vacuum state and ensuring the high quality of the product.
