[0001] This utility model relates to the field of elevator door frame processing technology, specifically to a sound-absorbing material cutting device for elevator door frame processing. Background Technology

[0002] As the most important component of the elevator lobby, the elevator door frame must have both directional and decorative functions so that people can more intuitively find the location of the elevator entrance and exit. However, because elevator operation generates noise, it is necessary to install sound insulation material of appropriate size inside the elevator door frame. After searching, the existing technology (announcement number: CN202120875744.3) describes a sound-absorbing material cutting device for elevator door frame processing. The document states that "by setting fixed pressure rollers and limiting plates, the entire sound-absorbing material is properly fixed on the conveyor belt, so that the conveying will not be deviated, and the machine can cut the sound-absorbing material of appropriate size; through the design of the cutting wheel and the cutter, the entire cutting process can be streamlined, so that the entire process can be carried out continuously, getting rid of the traditional one-by-one cutting method, thereby greatly improving production efficiency." However, the continuous cutting of the cutting wheel in the existing technology is prone to the problem that the cutting blade heats up, affecting the cutting effect of the sound-absorbing material. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a sound-absorbing material cutting device for elevator door frame processing is provided to solve the problem that continuous cutting by the cutter wheel in existing technologies easily leads to the cutting blade heating up and affects the cutting effect of the sound-absorbing material.

[0004] To achieve the above objectives, a sound-absorbing material cutting device for elevator door frame processing is provided, comprising: a cutting machine body, wherein a conveyor belt is installed on the inner side of the cutting machine body.

[0005] A cutting blade is provided at the upper right end of the conveyor belt. A heat sink is attached to the upper half of the cutting blade. The inner side of the heat sink is screwed to the cutting blade through the inner ring of a bearing. An air outlet is provided on the left side of the heat sink, and an air inlet is installed on the right side of the heat sink. A fan is installed at the upper end of the air inlet. A threaded post passes through the middle of the cutting blade and the heat sink. The heat sink is clamped and fixed on the post surface by a nut block. A motor is connected to the rear end of the threaded post through a rotating shaft. Cutting tools are distributed on the right side of the cutting blade.

[0006] Furthermore, a laser sensor is installed on the inner wall surface of the rear side of the cutting machine body, and a fixed frame and a support frame are welded to the upper end of the cutting machine body.

[0007] Furthermore, a hydraulic column is fixed to the upper surface of the support frame, and a tool holder is connected to the lower end of the hydraulic column. A cutting tool is screwed onto the lower end of the tool holder.

[0008] Furthermore, an adjusting stud is screwed onto the surface of the fixing frame, and an auxiliary roller is connected to the lower end of the adjusting stud via a roller frame; and the auxiliary roller is located at the upper end of the conveyor belt.

[0009] Furthermore, a limiting frame is welded to the inner side wall of the cutting machine body, and a limiting plate is inserted into the limiting frame. The limiting plate is screwed and fixed to the lower surface of the heat sink.

[0010] Furthermore, the front end bearing of the threaded column is connected to the inner wall of the cutting machine body, and a distance sensor is fixed to the rear side of the heat sink.

[0011] Furthermore, a bearing is installed in the middle of the heat sink, and a sponge lubrication column is sleeved on the inner side of the heat sink; and the sponge lubrication column is attached to the front and rear blades of the cutting blade.

[0012] The beneficial effects of this utility model are as follows: the sound-absorbing material cutting equipment for elevator door frame processing uses cutting blades and cutting tools to cut the width and length of the sound-absorbing material for the door frame. The fan blows air from the heat dissipation hood, with air entering from the right and exiting from the left, accelerating the airflow on the surface of the continuously rotating cutting blades. This removes the heat generated by the continuous cutting of the blades, thus accelerating the heat dissipation of the blades, reducing the temperature rise caused by continuous cutting, slowing down the wear of the cutting tools, and improving the cutting quality of the cutting equipment. The cutting distance of the cutting blades is adjusted and positioned by the nut block on the surface of the threaded column, making it convenient to adjust the cutting distance of the cutting equipment and facilitating the cutting of sound-absorbing materials for elevator door frames of different sizes.

[0018] Reference Figures 1 to 4 As shown, this utility model provides a cutting device for sound-absorbing materials used in elevator door frame processing, including: a cutting machine body 1, and a conveyor belt 11 installed on the inner side of the cutting machine body 1.

[0019] A cutting blade 2 is provided at the upper right end of the conveyor belt 11. A heat sink 22 is attached to the upper half of the cutting blade 2. The inner side of the heat sink 22 is screwed to the cutting blade 2 through the inner ring of the bearing component 26. An air outlet 23 is provided on the left side of the heat sink 22. An air inlet 25 is installed on the right side of the heat sink 22. A fan 21 is installed at the upper end of the air inlet 25. A threaded post 5 passes through the middle of the cutting blade 2 and the heat sink 22. The heat sink 22 is clamped and fixed on the surface of the threaded post 5 by a nut block 51. A motor 52 is connected to the rear end of the threaded post 5 through a rotating shaft 53. Cutting tools 3 are distributed on the right side of the cutting blade 2.

[0020] First, adjust the cutting distance between the two sets of cutting blades 2 on the threaded column 5, and clamp and fix them with nut block 51. Then, set the cutting length value of the cutting tool 3. Place the sound-absorbing material of the elevator door frame on the surface of the conveyor belt 11 of the cutting machine body 1. Adjust the lowering position of the auxiliary roller 4 so that the auxiliary roller 4 rolls and fits against the upper surface of the sound-absorbing material to limit the deviation of the sound-absorbing material. At this time, the conveyor belt 11 moves the sound-absorbing material to the rotating cutting blade 2 and cuts the width of the sound-absorbing material. During the cutting process, the fan 21 blows the airflow in the heat sink 22 from the right to the left and discharges it. The fast-flowing air carries away the heat from the surface of the cutting blade 2, which facilitates the heat dissipation effect of the cutting blade 2, reduces the temperature rise caused by the continuous cutting of the cutting blade 2, and slows down the wear of the cutting tool. Then, the laser sensor 14 senses the length of the sound-absorbing material movement. When the set length value is reached, the cutting tool 3 presses down to cut, and the sound-absorbing material of the appropriate size can be obtained.

[0021] In this embodiment, a laser sensor 14 is installed on the inner rear wall surface of the cutting machine body 1. A fixed frame 12 and a support frame 13 are welded to the upper end of the cutting machine body 1. A hydraulic column 31 is fixed on the upper surface of the support frame 13, and a tool holder 32 is connected to the lower end of the hydraulic column 31. A cutting tool 3 is screwed onto the lower end of the tool holder 32. An adjusting stud 42 is screwed onto the surface of the fixed frame 12, and an auxiliary roller 4 is connected to the lower end of the adjusting stud 42 through a roller frame 41; and the auxiliary roller 4 is located at the upper end of the conveyor belt 11.

[0022] In a preferred embodiment, the laser sensor 14 and the cutting tool 3 are positioned on the same horizontal line, facilitating the detection of the length of the sound-absorbing material's movement. The hydraulic column 31 pushes the cutting tool 3 downwards to cut the sound-absorbing material of the elevator door frame to the required length. Rotating the adjusting stud 42 causes the auxiliary roller 4 to move up and down, making it roll into contact with the sound-absorbing material on the surface of the conveyor belt 11, thus limiting the deviation of the sound-absorbing material.

[0023] In this embodiment, a limiting frame 15 is welded to the inner wall of the cutting machine body 1, and a limiting plate 28 is inserted into the limiting frame 15. The limiting plate 28 is screwed and fixed to the lower surface of the heat sink 22. A bearing 26 is installed in the middle of the heat sink 22, and a sponge lubrication column 24 is sleeved on the inner side of the heat sink 22; the sponge lubrication column 24 is attached to the front and rear blades of the cutting blade 2.

[0024] In a preferred embodiment, the limiting plate 28 inserted into the limiting frame 15 prevents the heat sink 22 from rotating, allowing it to move only horizontally back and forth. The bearing component 26 inside the heat sink 22 is easily connected to the threaded post 5 and screwed to the cutting blade 2. When the threaded post 5 drives the inner ring of the bearing component 26 to rotate, it drives the screwed cutting blade 2 to rotate and cut simultaneously. The sponge lubrication post 24 absorbs lubricating oil, facilitating the application of lubricating oil to the surface of the cutting blade 2, reducing friction during cutting, and preventing the cutting blade 2 from becoming excessively dry and affecting the cutting effect.

[0025] In this embodiment, the front bearing of the threaded column 5 is connected to the inner wall of the cutting machine body 1, and the distance sensor 27 is fixed on the rear side of the heat sink 22.

[0026] In a preferred embodiment, the threaded post 5 is driven by the motor 51 to rotate, thereby driving the cutting blade 2 to rotate and cut. The distance sensor 27 detects the distance between the two sets of heat sinks 22, allowing for convenient adjustment of the cutting distance of the cutting blade 2.

[0027] This utility model's sound-absorbing material cutting equipment for elevator door frame processing effectively solves the problem in the prior art where continuous cutting by the blade wheel easily leads to blade overheating, affecting the cutting effect of the sound-absorbing material. It facilitates faster heat dissipation of the cutting blade, reduces the temperature rise caused by continuous cutting, slows down the wear of the cutting tools, improves the cutting quality of the cutting equipment, and allows for convenient adjustment of the cutting spacing. It is suitable for cutting sound-absorbing materials for elevator door frames of different sizes and is applicable to sound-absorbing material cutting equipment for elevator door frame processing.
