Description

Technical Field

[0001] The invention relates to the technical field of fire door plate production and processing equipment, in particular to a plate cutting operation platform for fire door production. Background Art

[0002] A fire door is a door specially designed for fire separation inside buildings. It can withstand the high temperature and smoke attack of fire for a certain period of time, and play the role of heat insulation, isolation and smoke isolation. It is crucial to ensure the safety of buildings and personnel. Fire doors are made of fireproof materials and special structural design. They can withstand high temperature and smoke attack and effectively prevent the spread of fire. Fire doors can effectively isolate fire and smoke, extend the evacuation time of personnel, avoid being trapped in the fire, and provide safety protection for escape.

[0003] Fire doors require cutting of panels during the production process, but with traditional cutting methods, dust is mostly scattered in a parabolic pattern under the action of cutting force and gravity, which not only poses a production hazard but also pollutes the environment. Summary of the invention

[0004] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a plate cutting work platform for fire door production, which solves the problem that in traditional cutting methods, dust is mostly scattered in a parabolic manner under the action of cutting force and gravity, which not only poses a production hazard but also pollutes the environment.

[0005] (II) Technical solution To achieve the above objectives, the present invention is implemented through the following technical solutions: a plate cutting work platform for fire door production, comprising a work box, a servo motor, a cutter and a workbench, the servo motor extends through the top of the work box to the inside and is fixedly connected to a driving rod, a plurality of connecting rods are fixedly connected to the outer surface of one end of the driving rod away from the driving end of the servo motor, and the plurality of connecting rods are distributed in a ring array, a plurality of annular driving tooth plates are arranged inside the work box, a plurality of driving teeth are fixedly connected to the bottom of the plurality of annular driving tooth plates, the radii of the plurality of annular driving tooth plates are different, the radii between two adjacent annular driving tooth plates are the same, the plurality of annular driving tooth plates are distributed in a sleeve-type manner, and two adjacent annular driving tooth plates are arranged in a sleeve-type manner. The annular driving gear plates are fixedly connected by a fixed shaft, and one end of the multiple connecting rods away from the driving rod is fixedly connected to the inner wall of the annular driving gear plate closest to it. A driving screw is arranged inside the working box, and the outer surface of the driving screw has two sections of threads with equal lengths and opposite rotation directions. The outer surface of the driving screw is threadedly sleeved with two driving adjustment seats, and the front and rear side walls of the two driving adjustment seats are slidingly connected to the inner wall of the working box through short shafts. The bottoms of the two driving adjustment seats are connected to the cutter through telescopic rods, and the two driving adjustment seats are threadedly sleeved on the two sections of the threaded outer surfaces of the outer surface of the driving screw, and the outer surface of the driving screw is fixedly sleeved with multiple transmission gears near one side.

[0006] Preferably, the teeth on the outer surfaces of the plurality of transmission gears are telescopically adjustable.

[0007] Preferably, a collecting plate is provided above the annular driving tooth plate.

[0008] Preferably, a plurality of supporting filter plates are arranged between the plurality of annular driving tooth plates, and a supporting filter plate is arranged between the driving rod and the annular driving tooth plate.

[0009] Working principle: When in use, place the plate to be cut on the top of the workbench, start the servo motor, and the driving end of the servo motor drives the annular drive tooth plate to rotate through the driving rod, the connecting rod and the fixed shaft. When different cutting strengths are required for different plates, the teeth on the outer surface of the transmission gear at different positions are selected to be in an extended state, and mesh with multiple driving teeth fixedly connected to the bottom of different annular drive tooth plates. Due to the different radii of multiple annular drive tooth plates, when the servo motor has a fixed driving power, it will drive the drive screw to perform a fixed period of forward and reverse motion at multiple unused linear speeds. Since the two drive adjustment seats arranged on the outer surface of the drive screw by the threaded sleeve are connected to the inner wall of the working box through a short shaft, the two drive adjustment seats will drive the two cutters to achieve periodic changes in distance, thereby achieving a cutting effect of bidirectional force, which is suitable for the cutting strength of different plates. During the cutting process, the high curvature of the upper surface of multiple annular drive tooth plates, fixed shafts and connecting rods will generate an upward negative pressure during the rotation process, and the dust generated by the cutting will be initially absorbed by the supporting filter plate and then absorbed by the collecting plate, thereby achieving a purification effect and protecting the production environment.

[0010] (III) Beneficial effects The present invention provides a plate cutting operation platform for producing fire doors. It has the following beneficial effects: 1. The plate cutting platform for the production of fire doors, when different cutting strengths are required for different plates, the teeth on the outer surface of the transmission gears at different positions are selected to be in an extended state, and are meshed and connected with multiple driving teeth fixedly connected to the bottom of different annular driving tooth plates. When the servo motor has a fixed driving power, it will drive the driving screw to perform a fixed periodic forward and reverse motion at multiple different linear speeds. The two driving adjustment seats will drive the two cutters to achieve periodic changes in distance, thereby achieving a bidirectional force cutting effect to suit the cutting strength of different plates. 2. The plate cutting work platform for the production of fire doors has multiple annular drive gear plates, fixed shafts and connecting rods with high curvature on the upper surface during the cutting process. An upward negative pressure will be generated during the rotation, and the dust generated by the cutting will be initially absorbed by the supporting filter plate and then absorbed by the collecting plate, thereby achieving a purification effect and protecting the production environment.
