Description

Technical Field

[0001] The utility model relates to the technical field of LED display screen box production, in particular to a steel belt cutting device with a protection mechanism. Background Art

[0002] The LED display cabinet refers to the external structure and shell of the LED display, which is usually made of metal, aluminum alloy, steel or high-strength plastic. Its main function is to provide protection and support for the LED display, and also to fix and connect various components during installation and maintenance.

[0003] In the production of LED display cabinets, steel strips need to be cut to make parts suitable for the cabinet frame structure. In order to ensure operational safety and reduce the splashing of metal debris, the existing steel strip cutting process usually uses a baffle to shield the cutting position.

[0004] However, in actual use of the above equipment, debris will splash around in the shield, affecting the cleanliness of the operating table. Although the use of baffles can reduce the splashing range of metal debris, the operating table needs to be cleaned and organized to remove the splashed debris, which will consume additional time and human resources, thus affecting the smooth progress of the overall production process; in view of this, we propose a steel strip cutting device with a protective mechanism.

DETAILED DESCRIPTION

[0024] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a steel strip cutting device with a protective mechanism, comprising an operating table 1, a control box 2 is fixedly connected to the bottom end surface of the operating table 1, a mounting frame 3 is fixedly connected to the top end surface of the operating table 1, a motor 5 is fixedly connected to the top end surface of the mounting frame 3, an output end of the motor 5 is fixedly connected to one end of a threaded rod 4, the other end of the threaded rod 4 passes through the inner top end surface of the mounting frame 3, an upper hemispherical cover 6 is threadedly connected to the side wall of the threaded rod 4, and a flexible The flexible pad 19 is in contact with the steel belt. Through the elastic deformation of the flexible pad 19, the gap between the upper hemispherical cover 6 and the steel belt is filled to prevent the spray water from overflowing. The upper hemispherical cover 6 is sleeved with the cutting structure 7. The axis of the cutting structure 7 is perpendicular to the top of the operating table 1. The cutting structure 7 can cut the steel belt. The outer wall of the upper hemispherical cover 6 is provided with a spray assembly, which includes a pipe body 8, a spray head 9, a straight spray hole 10, a rotating spray hole 11, a bracket 15, a rotating shaft 16, a turbine 17 and a connecting rod 18.

[0025] In one embodiment of the utility model, the outer wall of the upper hemispherical cover 6 is sleeved with the tube body 8, and the end of the tube body 8 located on the inner side of the upper hemispherical cover 6 is sleeved with a spray head 9, and the end face of the spray head 9 is provided with a straight spray hole 10, and the side wall of the straight spray hole 10 is fixedly connected to one end of the rotary spray hole 11, and the other end of the rotary spray hole 11 passes through the side wall of the spray head 9, and the top end face of the operating table 1 is provided with a through hole 12, and the bottom end face of the through hole 12 is fixedly connected to the lower hemispherical cover 13, and the outer wall of the lower hemispherical cover 13 is sleeved with the discharge pipe 14, and the axis of the upper hemispherical cover 6 coincides with that of the lower hemispherical cover 13, and the radius of the upper hemispherical cover 6 and the lower hemispherical cover 13 are equal. The spray water carries metal debris through the through hole 12 into the lower hemispherical cover 13, and then is discharged through the discharge pipe 14.

[0026] The motor 5 starts to drive the threaded rod 4 to rotate, further making the upper hemispherical cover 6 move longitudinally. The longitudinal movement of the upper hemispherical cover 6 can drive the cutting structure 7 to move downward to achieve cutting of the workpiece. When the upper hemispherical cover 6 moves downward, the flexible pad 19 abuts against the steel belt. The flexible pad 19 fills the gap between the upper hemispherical cover 6 and the steel belt through elastic deformation to prevent the spray water from overflowing. The spray water passes through the pipe body 8 and the spray head 9, and a part of the water is directly sprayed out through the straight spray hole 10. The straight spray hole 10 is directly facing the cutting part, so that the cutting process can be cooled. Due to the trumpet-shaped structure of the inner wall of the spray head 9, part of the water is under pressure. Under the action of force, the water is sprayed out through the rotating spray hole 11. Since the spray angle of the rotating spray hole 11 is not perpendicular to the surface of the cylinder and has a certain impact force, the momentum of the spray water will have a horizontal component. The force of this horizontal component will apply a torque to the spray head 9, generating a torque effect, so that the spray head 9 rotates, and then sprays in a cavity formed by the upper hemispherical cover 6 and the operating table 1, and the metal debris scattered in the cavity is flushed into the lower hemispherical cover 13 through the through hole 12, and then discharged from the cutting device through the discharge pipe 14, without the need for manpower to clean up, so as to promote the smooth progress of the overall production.

[0027] In addition, in order to further improve the rotation effect of the spray head 9, the inner wall of the tube body 8 is fixedly connected with a bracket 15, the bracket 15 is sleeved with the rotating shaft 16, the side wall of the rotating shaft 16 is fixedly connected with a turbine 17, the side wall of the rotating shaft 16 is fixedly connected to one end of the connecting rod 18, and the other end of the connecting rod 18 is fixedly connected to the inner wall of the spray head 9. The spray liquid flowing in the tube body 8 can drive the turbine 17 to rotate, and the rotational force of the turbine 17 drives the rotating shaft 16 to rotate, which is further transmitted to the spray head 9 through the connecting rod 18, so that the rotation effect of the spray head 9 is better, and the cleaning effect inside the cavity is improved.

[0028] In the utility model, when in use, the motor 5 is started to drive the threaded rod 4 to rotate, further making the upper hemispherical cover 6 move longitudinally, and the longitudinal movement of the upper hemispherical cover 6 can drive the cutting structure 7 to move downward to achieve cutting of the workpiece. When the upper hemispherical cover 6 moves downward, the flexible pad 19 abuts against the steel belt, and the flexible pad 19 fills the gap between the upper hemispherical cover 6 and the steel belt through elastic deformation to prevent the spray water from overflowing. The spray water passes through the pipe body 8 and the spray head 9, and a part of the water is directly sprayed out through the straight spray hole 10, and the straight spray hole 10 is directly facing the cutting part, so that the cutting process can be cooled down. 9 has a trumpet-shaped structure on the inner wall, and part of the water is sprayed out through the rotating spray hole 11 under the action of pressure, so that the spray head 9 rotates, and then sprays a cavity formed by the upper hemispherical cover 6 and the operating table 1, and the metal debris scattered in the cavity is flushed into the lower hemispherical cover 13 through the through hole 12, and then discharged from the cutting device through the discharge pipe 14. Furthermore, the spray liquid flowing in the pipe body 8 can drive the turbine 17 to rotate, and the rotation force of the turbine 17 drives the rotating shaft 16 to rotate, and is further transmitted to the spray head 9 through the connecting rod 18, so that the rotation effect of the spray head 9 is better, and the cleaning effect of the cavity is improved.
