Background technique:

A conveyor belt having a traction member generally includes a traction member, a carrier member, a driving device, a tensioning device, a redirecting device, a support member, and the like. The traction member is used for transmitting the traction force, and the conveyor belt, the traction chain or the rigid rope can be used; the bearing member is used for carrying materials, and there is a hopper, a bracket or a spreader; the driving device powers the conveyor, generally by an electric motor, a speed reducer and Brake (stopper) and other components; the tensioning device generally has two types of screw type and heavy hammer type, which can maintain the tension and sag of the traction piece to ensure the normal operation of the conveyor belt; the support member is used to support the traction member or load For the components, rollers, rollers, and the like can be used. For longer conveyor belts, it is often necessary to dock two conveyor belts to achieve a longer belt length. Since the conveyor belt often needs to withstand a large tensile force during the transfer process, it is critical to maintain a certain butt joint strength of the butt conveyor belt. In addition, it is also important to keep the butt joint between the butt conveyors as flat as possible, because higher flatness will reduce the vibration or runout of the material during transport, thereby improving the transmission quality, transportation efficiency and equipment life.

Summary of the invention

The inventor of the present invention, in combination with years of research and development experience, has developed a conveyor belt butt fastening device comprising a collet, the gap inside the collet allowing the belt ends of the two conveyor belts to penetrate therein; the first fastening bolt, One side of the collet penetrates an open end of the collet; a first fastening nut is disposed on the other side of the collet and cooperates with the first fastening bolt to fasten the collet a second and a third fastening bolt, the second and third fastening bolts are respectively disposed at two sides of the collet and respectively penetrate to a gap of the collet; a transition straight rod, the transition straight rod The axial direction is perpendicular to the axial directions of the first, second and third fastening bolts, and the transition straight rod is configured to be inserted between the belt ends of the two conveyor belts; and a straight rod nut, Cooperating with the transition straight rod to fasten the transition straight rod. Preferably, in accordance with a preferred embodiment of the present invention, in the above-described belt butt fastening device, the transition straight rod is composed of an elongated rod and a pair of gears at the top end of the elongated rod, wherein the gear The wheel center is disposed at both ends of a crossbar fixed to the elongated rod, and the gear is allowed to rotate about the wheel center, wherein the plurality of teeth on the gear are made of an elastic material. Preferably, in accordance with a preferred embodiment of the present invention, in the above-described belt butt fastening device, further comprising two bent steel sheets fixed to the chuck via the second and third fastening bolts, respectively On both sides, wherein the bent surface of the bent steel sheet covers the fixing nut. Preferably, according to a preferred embodiment of the present invention, in the above-described belt butt fastening device, the second and third fastening nuts are further provided, and the second and third fastening bolts are respectively disposed on the clip The same side of the head to secure the second and third fastening bolts, respectively. Preferably, in a preferred embodiment of the present invention, in the above-described belt butt fastening device, a U-shaped clip is further inserted on the bent steel sheet, and one side of the U-shaped clip is located in the Bent between the steel sheet and the collet. By the cooperation of the two sets of fastening bolts and nuts, the belt butt fastening device of the present invention can securely couple the two conveyor belts to obtain a longer belt length. In addition, the unique transition straight rod structure of the invention can improve the flatness of the abutting faces of the two conveyor belts, avoid the phenomenon that the materials are turned over, folded and slipped into the gap during the conveying process, and improve the conveying quality, transportation efficiency and equipment. Life expectancy. In addition, the method of the present invention also has the advantages of low cost, convenient processing, and the like. The foregoing description of the preferred embodiments of the present invention
