[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 5 The utility model provides a technical solution: a disc scissors shaft quick installation frame, comprising at least two parallel support shafts 1, such as Figure 5 As shown, a telescopic mechanism 16 is provided at the middle position of the top of the frame 13 of the longitudinal cutting machine. The telescopic mechanism 16 is a cylinder, an electric lifting rod or a hydraulic cylinder. The lower part of the telescopic mechanism 16 is connected to the middle part of the U-shaped frame 17 with the opening facing downward, so that the telescopic mechanism can drive the U-shaped frame 17 to adjust the height up and down;

[0027] The bottom ends of the U-shaped frame 17 are connected to the sliders 18 respectively. Figure 5 As shown, the support shaft 1 is located between the sliders 18, and its two ends are respectively connected to the sliders 18, each slider 18 is installed on the support rail 19, and the support rail 19 is installed on the inner wall of the frame 13. When the U-shaped frame 17 is lifted or lowered by the telescopic mechanism, the U-shaped frame 17 can drive the support shaft 1 to move up and down along the support rail 19.

[0028] like Figure 1 As shown, a plurality of adjustment seats 2 are provided on the sliding sleeve of the support shaft 1. Specifically, a through hole 11 is opened on the adjustment seat 2, and then the support shaft is passed through the through hole. Each adjustment seat 2 is provided with a locking member that can be adjusted to a preset position. The locking member here is a locking bolt 3. When the adjustment seat 2 is adjusted to the preset position, the locking bolt 3 can be screwed to make it abut against the support shaft 1, so that the adjustment seat 2 is fixed.

[0029] A first connecting plate 4 is provided at the bottom of each adjustment seat 2, and a tool shaft frame is provided under each first connecting plate 4. The tool shaft frame is used to install and support the support arm 7. The tool shaft frame includes a second connecting plate 5 detachably connected under the first connecting plate 4, that is, the edges of the first connecting plate 4 and the second connecting plate 5 are fastened by bolts.

[0030] A support arm 7 is connected to the bottom of each second connecting plate 5, and the support arms 7 are all inclined downward, so that the support arms 7 are all inclined in one direction; a bearing seat 14 is provided at the bottom of the support arm 7, and a knife shaft 10 is rotatably installed in the bearing seat 14, and both ends of the knife shaft 10 extend out of the bearing seat 14 respectively;

[0031] A disc shear 9 is detachably mounted on one end of the cutter shaft 10. Specifically, Figure 4 and Figure 5 As shown, a stopper 15 is coaxially provided at one end of the cutter shaft 10 for mounting the disc shears 9. The center hole of the disc shears 9 is put on the cutter shaft 10 and contacts the stopper 15. An external thread structure is provided at the end of the cutter shaft 10. A locking nut 8 is provided on the external thread. The disc shears 9 is firmly fixed on the stopper 15 by tightening the locking nut to prevent the disc shears 9 from shaking or tilting.

[0032] The end of the knife shaft 10 away from the disc shear 9 is connected to the driving device arranged on the support arm 7, and the driving device includes a driving motor 6 arranged on one side of the top of the support arm 7, and the rotating shaft of the driving motor 6 passes through the other side of the support arm 7. The end of the knife shaft 10 and the rotating shaft of the driving motor 6 are both provided with pulleys 12, and the two pulleys 12 are connected by a belt. The pulleys 12 can be synchronous wheels, and the two synchronous wheels can be connected by a synchronous belt. Therefore, when the driving motor 6 rotates to drive the pulley 12 to rotate, the pulley 12 drives the disc shear 9 to rotate rapidly.

[0033] Furthermore, because the disc shear 9 is a wearing part during use, when a disc shear 9 reaches the end of its service life, it needs to be replaced. The stopper 15 is made into a regular polygon. During the operation, a wrench can be clamped on the stopper 15, and then the other hand also holds the wrench and clamps on the locking nut 8, so that the disc shear 9 can be easily disassembled and installed on the knife shaft 10.

[0034] Specifically, when the utility model is used, Figure 5 As shown, the telescopic mechanism 16 drives the knife shaft 10 to move up and down, so that the disc shear 9 on the knife shaft 10 descends to cut. When the disc shear 9 needs to be replaced or a thin plate is laid thereunder, the disc shear 9 can be raised under the drive of the telescopic mechanism.

[0035] The utility model has the advantages that, firstly, each adjustment seat 2 corresponds to a knife shaft frame, and a disc shear 9 is provided at the bottom of each knife shaft frame, so that the number of disc shears 9 on the support shaft 1 is multiple, and when the adjustment seat is adjusted, the spacing between the disc shears 9 can be changed, so that multiple thin plates can be sheared at one time, such as Figure 5 At the position indicated by the arrow A, a shearing platform is provided on the frame below the circular shear 9, and a shearing opening is provided below the shearing platform corresponding to the circular shear 9. When shearing, the circular shear 9 is tangent to the feeding direction of the shearing opening;

[0036] Secondly, each knife shaft frame is detachable, that is, the bolts between the first connecting plate 4 and the second connecting plate 5 can be loosened to disassemble it, which is convenient for repair and maintenance.

[0037] Based on the above embodiment, it can be further optimized that a whetstone in contact with the disc shears 9 is provided on the top of the support arm.
