A shrapnel is installed inside the voltage stabilizing shell. One end of the shrapnel is installed with a spring and there are multiple springs. One end of the spring is inlaid with a breathable material layer. One end of the voltage stabilizing shell is installed with an air pipe. In the utility model, a voltage stabilizing device is installed inside the device. When the adhesive is placed inside, when the internal pressure is too high, the tank body will not expand, and no dangerous accidents such as explosion will occur. When sealing, it is convenient to extract the adhesive inside, and the amount of the adhesive inside can be observed and cleared outside, which can avoid frequently opening the sealing cover plate and will not pollute the adhesive inside, so that the adhesive retains its effect.

[0004] The above-mentioned existing technical solutions have the following deficiencies: The preparation of the flocking adhesive usually involves the mixing of multiple components. When the above-mentioned technical solutions are used, it is inconvenient to mix the multiple materials of the flocking adhesive and inconvenient to dredge the blanking. On the one hand, there is a lack of a stirring and mixing structure inside the tank body, which is inconvenient to evenly mix the materials for preparing the flocking adhesive and the forming quality of the flocking adhesive. On the other hand, the material is prone to sticking during discharging, which is easy to cause blockage, and then affects the blanking of the flocking adhesive. Therefore, corresponding improvements are needed. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sealing device for a pollution-proof flocking adhesive to solve the problem of inconvenient blanking dredging of the existing sealing device for a flocking adhesive mentioned in the above background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: A sealing device for a pollution-proof flocking adhesive, comprising a sealing box and a closing cover. The top of the sealing box is provided with a closing cover, and a sealing plug is fixed to the bottom of the closing cover. A threaded rod is provided at the top of the closing cover;

[0007] Both ends of the bottom of the sealing box are provided with blanking pipes, and blanking boxes are fixed to the bottoms of the blanking pipes. There are two blanking boxes. A protective box is fixed between the blanking boxes. A servo motor is fixedly connected between the blanking boxes through a fixing plate, and a connecting rod is fixedly connected to the output shaft end of the servo motor. A driving gear is sleeved outside the connecting rod, and driven gears are meshed on both sides of the driving gear. A connecting rod is fixedly connected to one side of the driven gear. An outlet pipe is provided at the bottom of the blanking box.

[0008] Preferably, a fixing bracket is sleeved outside the threaded rod, and one side of the fixing bracket is fixed to both sides of the sealing box.

[0009] Preferably, sealing blocks are fixed to both sides inside the sealing box, and sealing blocks are fixed to both sides outside the sealing plug.

[0010] Preferably, blanking baffles are fixed to both sides inside the outlet pipe. A blanking port is provided on the outlet pipe. Telescopic springs are fixed to both sides outside the outlet pipe, and a support plate is fixed to the bottom of the telescopic spring.

[0011] Preferably, a sealing block is fixedly connected to the top of the support plate, and the diameter of the sealing block is smaller than the width of the blanking port.

[0012] Preferably, a sleeve block is sleeved outside the connecting rod, and mixing rods are fixed to both sides of the sleeve block. The cross section of the mixing rod is quadrilateral.

[0013] Preferably, stirring rods are provided on both sides of the connecting rod, and the cross section of the stirring rod is rectangular. The stirring rod is arranged inside the blanking box.

[0014] Compared with the prior art, the beneficial effects of the present utility model are: The sealing device for the pollution-proof flocking adhesive realizes convenient mixing and stirring of the materials for preparing the flocking adhesive, making them blend evenly, facilitating self-sealing of the material port and closing of the sealing device for the flocking adhesive, and avoiding pollution of the flocking adhesive;

[0015] By starting the servo motor, the servo motor drives the connecting rod to rotate, and the connecting rod drives the driven gear to rotate, and the driven gear drives the connecting rod to perform meshing motion. Two connecting rods are provided, and even if the connecting rods rotate in opposite directions, the sleeve block and the mixing rod are driven to rotate by the connecting rod, so that the mixing rod mixes and stirs the flocking adhesive material inside the sealing box to make it blend evenly and improve the quality of the flocking adhesive. At the same time, the connecting rod drives the stirring rod to rotate, and even if the stirring rod mixes and stirs the flocking adhesive material falling into the blanking box, the flocking adhesive material is prevented from sticking during the blanking process and causing blockage, so that the three rotation directions can be stirred and mixed synchronously, thereby improving the quality and efficiency of preparing the flocking adhesive, and then improving the functionality of the sealing device.

[0016] As the flocking adhesive falls into the discharge pipe, the blanking baffle and the sealing block are in a clamping relationship. When the weight of the flocking adhesive is large, the sealing block will be driven to move downward, and the synchronous telescopic spring will be stretched, even if the flocking adhesive is discharged through the blanking port. On the contrary, when the weight of the flocking adhesive is small and insufficient to drive the sealing block to move downward, the telescopic spring is in its original state, so that the blanking baffle and the sealing block are in a connected state, that is, the blanking port is closed, which is convenient for realizing self-sealing of the material port, improving the sealing performance of the sealing device, and preventing the internal flocking adhesive from being infected.

[0017] The material for preparing the flocking adhesive is transported to the interior of the sealing box, the sealing block and the sealing clamp are engaged with each other, and the sealing plug seals the opening of the sealing box. Then, the threaded rod is rotated to drive the closing cover down, thereby strengthening the sealing effect of the closing cover on the sealing box, and keeping the sealing box in a closed state to prevent external impurities from entering and contaminating the material inside the sealing box, thereby affecting the preparation of the flocking adhesive, resulting in poor flocking adhesive production effect and pollution during use.

By using the settings of the driving gear 10, the driven gear 11, the blanking baffle 1301 and the sealing block 16, the materials inside the sealing device for the flocking adhesive can be evenly stirred to avoid blockage, and the material outlet can be self-sealed to avoid contamination. Therefore, the following technical solutions are disclosed. For details, please refer to Figure 1 , Figure 4 , Figure 5 There are two blanking boxes 6, and a protective box 7 is fixed between the blanking boxes 6. A servo motor 8 is fixedly connected between the blanking boxes 6 through a fixing plate. The output shaft end of the servo motor 8 is fixedly connected with a connecting rod 9. The driving gear 10 is sleeved on the outside of the connecting rod 9. The driving gear 10 is meshed with the driven gears 11 on both sides. One side of the driven gear 11 is fixedly connected with a connecting rod 12. The bottom of the blanking box 6 is provided with a discharge pipe 13. Blanking baffles 1301 are fixed on both sides inside the discharge pipe 13. A blanking port 1302 is arranged on the discharge pipe 13.

The top of the support plate 15 is fixedly connected with a sealing block 16. The diameter of the sealing block 16 is smaller than the width of the blanking port 1302. A sleeve block 18 is sleeved on the outside of the connecting rod 9. Mixing rods 19 are fixed on both sides of the sleeve block 18. The cross-section of the mixing rod 19 is quadrilateral. Stirring rods 17 are arranged on both sides of the connecting rod 12. The cross-section of the stirring rod 17 is rectangular. The stirring rod 17 is arranged inside the blanking box 6.
