Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a limiting structure for cutting machines. Background Art

[0002] Cutting machines are indispensable equipment for some light industries. Traditionally, cutting machines are machines that use the force of the machine's movement to apply pressure to the cutting die to perform punching processing on non-metallic materials (generally referring to plate-shaped materials). Modern cutting machines have undergone some changes, and advanced technologies such as high-pressure water jets and ultrasound have begun to be used in leather punching technology, but people still classify these devices as cutting machines. At present, traditional cutting machines usually only have simple cutting functions during use. When the specifications of the cutting materials are different, if the materials are not limited, cutting deviations are likely to occur, which in turn affects the yield of the cut materials. At the same time, the manual feeding method increases the workload of cutting. To this end, we provide a cutting machine limit structure to solve the above problems. Utility Model Content

[0008] The beneficial technical effect of the utility model is that the user drives the screw to rotate through the hand wheel, and then the rotating screw drives the limit plate to move closer to or away from the conveyor belt, so that the distance between the two limit plates can be adapted to the width of the material to be cut.

[0013] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0014] The utility model proposes a cutting machine limiting structure, including a base 1, a top frame 2 is fixedly provided on the top of the base 1, a cylinder 8 is provided on the top of the discharge side of the top frame 2, and a knife die 9 is provided on the movable end of the cylinder 8. The operation of the cylinder 8 can drive the knife die 9 to press down, so that the knife die 9 can cut the material to be cut on the top of the base 1. In actual use, two synchronously controlled cylinders 8 are usually used to drive the knife die 9 to press down, ensuring the stability of the movement of the knife die 9. Two limiting plates 3 are correspondingly provided on the inner side of the feed end of the top frame 2, and the two limiting plates 3 are mutually Two limit rods 4 are fixedly provided on the surfaces facing away from each other. The two adjacent limit rods 4 are symmetrically arranged with the limit plate 3 as the center, and the limit rods 4 are movable through the corresponding side walls of the top frame 2. Through the limiting cooperation between the limit rods 4 and the top frame 2, the limit plate 3 can be stably approached or moved away from the cutting die 9, so that the two limit plates 3 can stably adjust the spacing. The limit plate 3 is located between the two limit rods 4 and is rotatably provided with a screw 5. The screw 5 is threadedly connected to the side wall of the top frame 2. Through the cooperation between the screw 5 and the top frame 2, the position of the limit plate 3 can be controlled.

[0015] Specifically, a plurality of grooves are provided on the limiting side of the limiting plate 3, in which balls 7 are rolled. The design of the balls 7 can convert the sliding friction between the cut material and the limiting plate 3 into rolling friction. A handwheel 6 is fixedly provided at one end of the screw 5. The purpose of its design is to drive the screw 5 to rotate by the handwheel 6.

[0016] Specifically, the cylinder 8 and the cutting die 9 are connected by a mounting plate 10, and the mounting plate 10 is fixedly arranged on the movable end of the cylinder 8. The bottom of the mounting plate 10 is fixedly connected to the cutting die 9 by bolts. By adding the mounting plate 10, the cutting die 9 can be disassembled, thereby facilitating the inspection and maintenance of the cutting die 9.

[0017] Specifically, two driving rollers 11 are rotatably arranged in the top groove of the base 1, and the outer walls of the two driving rollers 11 are movably connected to the conveyor belt 12. A driving component is provided at the shaft end of the driving roller 11 on the discharge end side. This design can drive the driving roller 11 through the driving component, and then drive the conveyor belt 12 to rotate, so that the cut material can move toward the cutting die 9 under the rotation of the conveyor belt 12, thereby replacing manual feeding.

[0018] Specifically, the driving assembly includes a motor 13 and a reducer 14. The motor 13 and the reducer 14 are both installed on one side of the outer wall of the base 1. The output end of the motor 13 is fixedly connected to the input end of the reducer 14. The output end of the reducer 14 is fixedly connected to the shaft end of the driving roller 11 on the discharge end side. The motor 13, as a power source, can reduce the output speed under the operation of the reducer 14, thereby driving the driving roller 11 to rotate.

Their structures and principles can be known to technical personnel through technical manuals or through conventional experimental methods. The models are compatible with this solution and can operate normally. All electrical components in this case are connected to their compatible power supplies through wires, and according to actual conditions, appropriate controllers are selected to meet control requirements. The specific connection and control sequence should refer to the following working principle. The electrical connection is completed in the order of working between the electrical components. The detailed connection means are well known in this field and will not be explained in detail for electrical control.

[0020] Working principle: When using the cutting machine, the distance between the two limit plates 3 can be adjusted according to the width of the material to be cut. The user drives the screw 5 to rotate through the handwheel 6, and then the rotating screw 5 drives the limit plate 3 to move closer to or away from the conveyor belt 12, so that the distance between the two limit plates 3 can be adapted to the width of the material to be cut. At this time, the motor 13 can be started. The motor 13 can reduce the output speed under the operation of the reducer 14, and drive the conveyor belt 12 to rotate through the drive roller 11 to realize the transportation of the material to be cut. At the same time, the operation of the cylinder 8 drives the knife die 9 under the mounting plate 10 to be pressed down until the material to be cut is cut, and under the subsequent rotation of the conveyor belt 12, the uncut material can continue to move forward, and the cut material falls off to the bottom of the base 1.
