Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-5 This utility model provides a technical solution:

[0020] A feeding mechanism for a shearing machine includes a workbench 1. The upper surface of the workbench 1 has an installation groove 11, in which a conveyor belt body 2 is installed. Two alternating positioning and pushing mechanisms 3 are fixedly installed on the outer surface of the conveyor belt body 2. A support frame 4 is fixedly installed on the left side of the upper surface of the workbench 1. A transverse positioning mechanism 5 and a longitudinal pressing mechanism 6 are installed in the support frame 4. The positioning and pushing mechanism 3 is used to smoothly push the plate into the transverse positioning mechanism 5. The transverse positioning mechanism 5 and the longitudinal pressing mechanism 6 work together to ensure that the plate is stably conveyed to the shearing area of ​​the shearing machine and fixed.

[0021] Before use, the left end of the workbench 1 is installed in the shearing area of the shearing machine. When in use, the plate is placed on the conveyor body 2, and the right end of the plate is positioned by the positioning and pushing mechanism 3 to prevent deviation during conveying. Then, under the pushing of the positioning and pushing mechanism 3, the plate is sent into the horizontal positioning mechanism 5 for horizontal accurate calibration positioning before shearing. In this process, the left edge of the plate extends beyond the edge of the workbench 1 to the shearing range of the shearing machine. At the same time, the plate is pressed by the longitudinal pressing mechanism 6 to prevent longitudinal displacement of the plate during shearing, ensuring the stability of the plate during shearing and the quality of the sheared plate, and reducing plate waste.

[0022] In combination Figure 1 and Figure 5 As shown in the drawings, the positioning and pushing mechanism 3 comprises a U-shaped plate 31, guide rods A311 are fixedly installed at the front and rear ends of the U-shaped plate 31, positioning plates A32 are slidably installed on the outer surfaces of the guide rods A311, and adjusting screws 33 are screw-connected to the front and rear ends of the U-shaped plate 31, and the outer ends of the adjusting screws 33 are rotatably connected to the corresponding positioning plates A32.

[0023] Before use, the positioning and pushing mechanism 3 has the function of adjusting according to the width of the plate. The specific adjustment method is as follows: forward or reverse screwing of the adjusting screws 33 can drive the positioning plates A32 to rotate outward or inward, and the distance between the two positioning plates A32 is adjusted to adapt to the positioning needs of plates of different widths. The appropriate positioning state is that the inner surfaces of the two positioning plates A32 are in contact with but not clamped to the outer surface of the plate. When the positioning and pushing mechanism 3 is moved to the left end of the conveyor body 2, it can be flipped downward to facilitate plate separation, and after separation, the plate is pushed into the horizontal positioning mechanism 5.

[0024] As shown in the drawings, Figure 1 The horizontal positioning mechanism 5 comprises a stepping motor 51, a positive and negative tooth bidirectional screw 52, and a guide rod B54. The stepping motor 51 is fixedly installed on the front surface of the support frame 4, and the output end of the stepping motor 51 is fixedly connected to the front end of the positive and negative tooth bidirectional screw 52. The positive and negative tooth bidirectional screw 52 is rotatably installed in the support frame 4, and two positioning plates B53 are symmetrically screw-connected to the outer surface of the positive and negative tooth bidirectional screw 52. The positioning plates B53 are slidably connected to the guide rod B54.

[0025] When the horizontal positioning mechanism 5 is in use, the stepping motor 51 is used to drive the positive and negative tooth bidirectional screw 52 to rotate, thereby driving the two positioning plates B53 to adjust the positioning distance inward or outward synchronously to adapt to the positioning of plates of different widths.

[0026] To adjust the limiting distance of the horizontal positioning mechanism 5 to be consistent with the limiting distance of the positioning and pushing mechanism 3, as shown in the drawings, Figure 3As shown, an infrared laser locator 531 is embedded in the rear surface of the positioning plate B53. The limit distance of the lateral positioning mechanism 5 can be determined by whether the infrared laser locator 531 illuminates the positioning plate A32 of the positioning and pushing mechanism 3.

[0027] Finally, as Figure 1 As shown, the longitudinal pressing mechanism 6 includes two vertical rods 61, both of which pass through the support frame 4. A fixing plate 62 is fixedly installed between the upper surfaces of the two vertical rods 61. An electric telescopic rod 63 is fixedly installed between the lower surface of the fixing plate 62 and the upper surface of the support frame 4. A pressure block 611 is fixedly installed on the lower surface of each vertical rod 61. The extension and retraction of the electric telescopic rod 63 can drive the vertical rods 61 and the pressure block 611 to move up and down through the fixing plate 62. When the plate reaches the shearing position, the electric telescopic rod 63 can be used to drive the vertical rods 61 to move down, and the pressure block 611 can be used to press and fix the plate, thereby ensuring the stability of the plate during the shearing process and ensuring the quality of the plate after shearing.
