Wire twisting machine and automatic opening and closing door thereof

Abstract

The invention discloses an automatic opening and closing door of a wire twisting machine. The automatic opening and closing door comprises a guide rail (1), a slider (3), a sliding seat (4), a movabledoor (2), at least two parallel ejector rods (11), a first cylinder (8), a second cylinder (20) and a third cylinder (7), the guide rail (1) is fixed onto a top plate in a box, the slider (3) is clamped on the guide rail (1) and can slide along the guide rail (1), the sliding seat (4) is horizontally arranged and fixedly connected with the slider (3), the movable door (2) is positioned on the outer side of the sliding seat (4), the ejector rods (11) are hinged to the upper portion of the inner side of the movable door (2) and the lower portion of the sliding seat (4), a cylinder of the firstcylinder (8) is fixed onto the lower portion of the sliding seat (4), a telescopic rod of the first cylinder (8) is connected with the ejector rods (11), the second cylinder (20) is horizontally arranged on the lower portion of the inner side of the movable door (2) and used for pushing the movable door (2) to move outwards, and the third cylinder (7) is used for driving the slider (3) to slide along the guide rail (1). The automatic opening and closing door effectively solves the problems that a door is not conveniently opened and closed and the like. The invention further discloses the wiretwisting machine comprising the automatic opening and closing door.

Description

technical field [0001] The invention relates to the technical field of the stranding machine industry, in particular to an automatic opening and closing door. In addition, the present invention also relates to a wire twisting machine comprising the above-mentioned automatic opening and closing door. Background technique [0002] The existing open and close doors are divided into windows that flip up and down and iron doors that switch in the left and right directions below, please refer to figure 1 , figure 1 It is a structural schematic diagram of a typical old model stranding machine in the prior art. Flip 01, like a flip phone, is flipped up and down. Flip 01 is not only labor-intensive, but also the operator has to put his upper body into the machine to operate "threading" and "replace parts", which is extremely inconvenient. Moreover, once the flip cover 01 is unstable, it will fall and hit the head of the personnel, which poses a great safety hazard. Here, the spac...
