Description

Technical Field

[0001] This utility model belongs to the field of coil feeding technology, specifically relating to an auxiliary device for feeding niobium foil coils for a shearing machine. Background Technology

[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. Its working principle is: by using a moving upper blade and a fixed lower blade with a reasonable blade gap, shearing force is applied to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions. A shearing machine includes a work plate, a gantry frame, and upper and lower blades. However, when cutting niobium foil rolls to a fixed size on a shearing machine, because the machine lacks a feeding support structure, one person holds the upright niobium foil roll while another person unfolds the niobium foil layer by layer from the starting end. This process requires two workers, resulting in low feeding efficiency and high labor intensity. There is also a risk of scratches and wear on the surface of the niobium foil during feeding. Therefore, to address these problems, it is necessary to design an auxiliary feeding device on the feeding side of the shearing machine. Utility Model Content

[0003] The technical problem solved by this utility model is to provide an auxiliary device for feeding niobium foil rolls to a shearing machine. By setting a triangular bracket with a support roller detachably and rotatably supported at the upper end by a left support device and a right support device on the feeding side of the shearing machine, the device provides conditions for the niobium foil roll to be unfolded layer by layer under the rotational support of the support roller. This solves the problems of high labor intensity, low feeding efficiency and high cost of manual feeding, reduces the difficulty of feeding niobium foil rolls, improves feeding efficiency and the surface quality of niobium foil, reduces labor costs, has a simple structure, novel design, is convenient and quick to operate, and has high application value.

[0004] The technical solution adopted in this utility model is: a niobium foil roll feeding auxiliary device for a shearing machine, including a triangular bracket. The upper ends of the left and right sides of the triangular bracket are respectively provided with a right support device and a left support device. The two ends of the support roller, which is located above the triangular bracket and is fitted with the niobium foil roll, are detachably and rotatably installed on the left support device and the right support device, respectively. One end of the support roller is fixed with an operating handle located outside the triangular bracket. The niobium foil roll is unfolded and fed layer by layer by rotating the support roller through the operating handle.

[0005] The right support device includes a right support, a right roller, and a movable seat. Both the right support and the movable seat are made of channel steel, and their slots face each other. The right support is fixed to the upper right side of the triangular bracket, and a semi-circular groove is formed in the middle of both side walls of the right support. Right rollers are symmetrically mounted on the right support on both sides of the semi-circular groove, and the right end of the support roller is supported in the semi-circular groove by two right rollers. One end of the movable seat is hinged to one end of the right support, and a right roller with a lower wheel surface lower than the lower edge of the movable seat is rotatably mounted in the middle of the U-shaped groove of the movable seat. When the movable seat is rotated until the lower wheel surface of the right roller on the movable seat contacts the corresponding end of the support roller, the connecting component at the other end of the right support detachably and fixedly to the corresponding end of the movable seat, thus completing the detachable rotatable installation of the end of the support roller on the upper right side of the triangular bracket.

[0006] Furthermore, the connecting assembly includes a connecting screw, the lower end of which is rotatably mounted to the other end of the right support via a pin. A groove is formed in the middle of the upper surface of the other end of the movable seat, and a washer and a locking nut located above the movable seat are adapted to and connected with the connecting screw that passes through the groove at the upper end, thereby realizing the locking and fastening connection between the right support and the other end of the movable seat.

[0007] Furthermore, the left support device includes a left support, a left roller, and a tilting seat. The left support is fixed to the upper left end of the triangular bracket, and a semi-circular groove is also formed in the middle of the two side walls of the left support. Left rollers are symmetrically mounted on the left support on both sides of the semi-circular groove, and the left end of the support roller is supported in the semi-circular groove by two left rollers. The tilting seat adopts a structure composed of a semi-circular plate in the middle and extension plates with outward extensions at both ends. A left roller is rotatably mounted in the middle of the top surface of the tilting seat. One end of the left support is rotatably connected to the extension plate at one end of the tilting seat. When the tilting seat is rotated until the lower wheel surface of the left roller on the tilting seat contacts the corresponding end of the support roller, the locking assembly at the other end of the left support detachably fixes the extension plate at the other end of the tilting seat, thus completing the detachable rotatable installation of the support roller end on the upper left side of the triangular bracket.

[0008] Furthermore, the left roller axle in the middle of the inner top surface of the flipping seat is connected to the connecting plate fixed at the corresponding end in the middle of the flipping seat.

[0009] Furthermore, the locking assembly includes a locking screw with its lower end rotatably mounted on the other end of the left support, and the upper end of the locking screw passes through the U-shaped groove at the corresponding end of the flip seat and is adapted to connect with the washer and nut.

[0031] The triangular support 1 is a frame consisting of two triangular frames and multiple crossbars 1-1 for connecting the triangular frames into one unit. In order to prevent the niobium foil roll from being damaged by friction due to contact and friction with the crossbars 1-1 on both sides of the support roller 4 during the unfolding of the niobium foil roll layer by layer, anti-wear felt is wrapped and fixed on the two crossbars 1-1 adjacent to the support roller 4 on both sides of the triangular support 1 to ensure the quality of the niobium foil roll when unfolding layer by layer.
