[0002] Roller press, also known as extrusion mill or roller mill, is a new type of energy-saving cement grinding equipment developed internationally in the mid-1980s. It has the function of replacing the high-energy-consuming and low-efficiency ball mill pre-grinding system, and reducing steel consumption and noise. In the field of cement production and manufacturing, cement raw materials are usually powdered materials, and the production of these powdered materials usually uses cement roller presses to crush larger-sized particles.

[0003] During use of the existing roller press, the side baffles on both side end faces of the feed structure are prone to material leakage, and the side baffles adopt an integrated connection structure. After the side baffles are worn, they are not easy to be replaced, which further causes serious material leakage.

[0004] Therefore, those skilled in the art provide a leakage-proof electric feeding device to solve the problems raised in the above background technology. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A leakage-proof electric feeding device comprises: a roller press, mounting frames are fixedly installed on both sides of the roller press, an outer feeding bucket is installed above the roller press, an inner feeding bucket is fixedly installed inside the outer feeding bucket by bolts, the bottom of the inner feeding bucket is movably connected to an opening and closing plate, the outer side of the opening and closing plate is movably connected to an electric cylinder, an outer baffle is installed at the bottom of the inner feeding bucket, and an inner baffle is provided on the inner side of the outer baffle, and disassembly bolts are interspersed between the outer baffle, the inner baffle and the outer feeding bucket.

[0008] As a further solution of the present invention, a connecting shaft for opening and closing rotation is provided between the opening and closing plate and the feeding inner bucket, and a movable shaft for movement is installed between the opening and closing plate and the output end of the electric cylinder.

[0009] As a further solution of the present invention, the outer baffle and the inner baffle are parallel to each other, and the outer baffle and the inner baffle are connected to each other with the feed outer hopper by replacing bolts.

[0010] As a further solution in the present invention, mortise holes are provided on the inner surfaces of the outer baffle and the inner baffle, mounting plates are installed on the outer sides of the outer baffle and the inner baffle, and tenons are fixed on the inner walls of the mounting plates.

[0011] As a further solution of the present invention, the mortise and tenon cooperate with each other to form a mortise and tenon joint connection, and the mounting plate is connected to the outer baffle and the inner baffle through the mortise and tenon.

[0012] As a further solution of the present invention, a squeezing roller is installed inside the roller press, and the outer wall of the roller press is electrically connected to a controller.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The outer feed hopper is set to an inner and outer two-layer structure, which is divided into an outer feed hopper and an inner feed hopper. An opening and closing plate is set at the bottom of the inner feed hopper. The opening and closing plate is opened and closed front and back. The length of the opening and closing plate is set to match the roller length between the extrusion rollers. The opening and closing plate is opened and closed front and back to control the flow rate by cooperating with the electric cylinder and the electric actuator. In this way, the opening and closing trajectory of the opening and closing plate moves along the arc of the roller surface of the extrusion roller to ensure that the material fills the extrusion cavity of the roller press and ensures that the material can fill the extrusion cavity at any bite angle position of the roller press to form a stable material column and improve the working efficiency of the roller press.
