[0004] Existing filling equipment has been found to have poor ease of adjusting the filling direction, making it difficult to adapt to filling needs in different locations. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a photocurable resin layer filling pressurization device that facilitates the filling of resin in different directions, improves the convenience of filling in different positions, and improves the compactness of filling by using a pressurizing head to pressurize the filling position.

[0006] This utility model discloses a layered filling and pressurizing device for photocurable resin, comprising a cylinder and a feed valve, the feed valve being connected to the upper part of the outer wall of the cylinder; it also includes a connecting structure, an adjusting device, a discharge head, discharge holes, and a pressurizing head. The discharge head is connected to the bottom end of the cylinder via the connecting structure, and multiple sets of discharge holes are circumferentially arranged on the lower part of the outer wall of the discharge head. The pressurizing head is located at the bottom end of the discharge head. An adjusting device is provided inside the cylinder to control the opening and closing of the multiple sets of discharge holes and to assist in the downward conveying of resin. The resin is conveyed into the cylinder through the feed valve, and the resin flowing into the cylinder flows downward into the discharge head. The adjusting device controls the opening of one set of discharge holes, thereby allowing the resin in the discharge head to flow outward through the discharge hole. By controlling the opening of the discharge holes at different positions, it is convenient to achieve resin discharge and filling in different directions, improving the convenience of filling needs at different positions. After filling is completed, the pressurizing head is used to pressurize the filling position to improve the compactness of the filling.

[0007] Preferably, the adjusting device includes a rotating shaft, a sealing plug, a groove, spiral blades, and a motor. The rotating shaft is rotatably installed inside the cylinder. The top end of the sealing plug is connected to the bottom end of the rotating shaft. The sealing plug is rotatably located inside the discharge head. The groove is located on the outer wall of the sealing plug. The spiral blades are installed on the outer wall of the rotating shaft. The motor is located at the top of the cylinder, and the output end of the motor is connected to the rotating shaft. The motor drives the rotating shaft to rotate, which in turn drives the sealing plug to rotate. After the sealing plug rotates, it drives the groove to move. When the groove moves to the side of one of the discharge holes, the discharge hole communicates with the discharge head, allowing the resin in the discharge head to be discharged through the discharge hole. At this time, the groove blocks the other discharge holes. By moving the groove to different positions, it is easier for the resin to be discharged from the discharge holes in different positions, improving the convenience of filling the resin in different directions. When the rotating shaft rotates, it drives the spiral blades to rotate, which assists in conveying the resin in the cylinder downwards, improving the resin conveying and discharge effect.

[0008] Preferably, it also includes an annular connector, a top plate, and screws. The annular connector is located on the upper part of the outer wall of the cylinder, the top plate is installed on the top of the annular connector, the top of the rotating shaft is rotatably installed on the top plate, the motor is installed on the top of the top plate, and multiple sets of screws are installed between the annular connector and the top plate. By disassembling the top plate, the convenience of opening the top of the cylinder is improved, and the convenience of removing, cleaning, and maintaining the rotating shaft, sealing plug, and spiral blades is improved.

[0009] Preferably, the connecting structure includes a connecting cylinder, which is connected to the bottom end of the cylinder body. The outer wall of the connecting cylinder is provided with external threads, and the upper part of the discharge head is provided with internal threads. The discharge head is connected to the connecting cylinder through the threads, thereby improving the convenience of loading and unloading the discharge head.

[0010] Preferably, it also includes a retaining ring and a sealing ring. The retaining ring is disposed on the inner wall of the discharge head, and the sealing ring is disposed on the outer wall of the retaining ring. When the discharge head is installed on the connecting cylinder, the top end of the sealing ring is pressed against the bottom end of the connecting cylinder to improve the sealing performance between the discharge head and the connecting cylinder.

[0011] Preferably, it also includes an observation window, which is located on the outer wall of the cylinder; this improves the convenience of observing the resin inside the cylinder.

[0012] Preferably, it also includes anti-slip components, which are installed on the outer wall of the cylinder to improve the anti-slip effect for personnel gripping the cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the resin is transported into the cylinder through the feed valve, and the resin entering the cylinder flows downward into the discharge head. The discharge head is opened by controlling one set of discharge holes through the adjustment device, so that the resin in the discharge head flows outward through the discharge hole. By controlling the opening of the discharge holes at different positions, it is convenient to realize the discharge and filling of resin in different directions, and improve the convenience of filling needs at different positions. After filling is completed, the filling position is pressurized by using the pressure head to improve the compactness of the filling. Attached Figure Description
