[0007] Furthermore, the surface of the sliding rod is sleeved with a first spring, and the two ends of the first spring are respectively fixedly connected to the surface of the connecting block and the surface of the limiting block. The first spring is arranged on the surface of the sliding rod, which can apply a reset elastic force to the limiting rod, thereby reducing the situation in which the limiting rod is difficult to reset and block the discharge block after the limiting rod moves away from the surface of the conveying frame when the equipment is in use.

[0008] Furthermore, a tooth groove is formed on the lower surface of the limiting rod, and a servo motor is fixedly connected to the side of the conveying frame. The servo motor is provided to facilitate limiting the uniform rotation of the half-toothed gear.

[0011] Furthermore, one end of the pull rod is fixedly connected to a second spring, and one end of the second spring away from the pull rod is fixedly connected to the inner wall of the pull groove. The second spring is provided to facilitate applying a restoring elastic force to the pull rod.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the equipment is in use, the user places the material to be pressed inside the discharge block, and then the discharge block moves to the surface of the hydraulic press through the conveying frame, and then the movable clamping block clamps the discharge block and moves it to the lower end of the pressing plate, and then the equipment is pressed. When using the equipment, the user starts the servo motor, and then the servo motor rotates to drive the half-tooth gear to rotate, and the rotation of the half-tooth gear drives the limiting rod to move, and the movement of the limiting rod drives the first spring to displace and deform to generate elastic force, and then the limiting rod is separated from one end of the discharge block, and then the discharge block moves. By setting the limiting device, the discharge block is effectively restricted, which plays a role in limiting the discharge block, reduces the situation that the discharge block moves at different speeds when the equipment is in use, and is easily accumulated between the conveying frame and the hydraulic press, making it difficult for the movable clamping block to effectively move the discharge block, thereby improving the practicality of the equipment.

[0015] 2. In the utility model, by setting a blocking device, before using the equipment, the user pulls the pull rod, and then the pull rod moves to drive the adjusting rod to move. When the pull rod moves, it drives the second spring to displace and deform to generate elastic force, and then the adjusting rod is separated from the inside of the adjusting groove, and then the rotating rod is freed from the restraint, and the blocking plate is rotated to adjust the angle. By setting the blocking device, the discharge block is effectively blocked, which plays a role in blocking the discharge block from approaching the side of the conveying rack, reducing the situation that when the equipment is in use, the discharge block moves to the side of the conveying rack close to the limiting device, causing the discharge block to be difficult to move and easily stuck at one end of the limiting rod and difficult to move, thereby improving the practicability of the equipment.
