[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A thermal insulation material fixed-length cutting device includes a workbench 1, a cutting mechanism 2 welded to the top of the workbench 1, and fixed-length mechanisms 3 welded to the bottom surfaces on both sides of the cutting mechanism 2.

[0027] The fixed-length mechanism 3 includes a fixed plate 31, several conveying rollers 32, connecting wheels 33, connecting belts 34, a servo motor 35, an absolute encoder 36, a laser displacement sensor 37, a trigger sensor 38, and a PLC controller 39. The fixed plate 31 is welded to the bottom surfaces of both sides of the cutting mechanism 2. The conveying rollers 32 are rotatably connected to the inner side of the fixed plate 31. The connecting wheels 33 are fixedly connected to the right side of the conveying rollers 32. The right side of the connecting wheels 33 is rotatably connected to the inner wall of the right side of the fixed plate 31. The connecting belt 34 is movably connected to the surface of the connecting wheels 33. The servo motor 35 is installed on the front side of the right side of the front fixed plate 31. The output end of the left side of the servo motor 35 passes through the fixed plate 31 and is fixedly connected to the right side of the right front connecting wheel 33.

[0028] In this embodiment: the workbench 1 supports and limits the cutting mechanism 2 and the length-fixing mechanism 3; the fixed plate 31 supports and limits the conveying roller 32, the connecting wheel 33, and the servo motor 35; the conveying roller 32 conveys the insulation material to the rear; the connecting wheel 33 and the connecting belt 34 synchronously transmit the power of the servo motor 35 to each conveying roller 32, ensuring consistent conveying speed and improving conveying stability; the servo motor 35 adjusts its speed according to the instructions of the PLC controller 39 to achieve uniform and variable speed conveying of materials, adapting to different cutting requirements; the absolute encoder 36 directly measures the rotation angle of the conveying roller 32 and accurately calculates the rotation angle based on the roller circumference. The material conveying distance has a power-off memory function, which can achieve high-precision length setting without repeated zeroing. The laser displacement sensor 37 can detect the length of the insulation material after the trigger sensor 38 is triggered, and assist the absolute encoder 36 in correcting measurement errors. The trigger sensor 38 detects the position of the front end of the material. When the trigger sensor 38 is triggered by the insulation material, it transmits the signal to the PLC controller 39. The PLC controller 39 controls the laser displacement sensor 37 to start. The PLC controller 39 integrates data from various sensors and motors, supports custom cutting length input, and automatically controls the entire process of material conveying, measurement and cutting to realize automated production.

[0029] Specifically, such as Figure 2 , Figure 3 As shown, the absolute encoder 36 is installed on the left side of the front conveyor roller 32, the laser displacement sensor 37 is installed on the front side of the top inner side of the cutting mechanism 2, the trigger sensor 38 is installed on the front side of the top of the cutting mechanism 2, and the PLC controller 39 is installed on the surface of the right side of the cutting mechanism 2.

[0030] Specifically, such as Figure 4 , Figure 5 As shown, the cutting mechanism 2 includes a cutting table 21, a cutting groove 22, a mounting groove 23, a lifting groove 24, a limiting rod 25, a support beam 26, an electric cylinder 27, and a cutting blade 28. The cutting table 21 is welded to the top of the workbench 1.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, the cutting groove 22 is opened at the bottom of the inner side of the cutting table 21, the mounting groove 23 is opened at the front side of the bottom of the inner side of the cutting table 21, the trigger sensor 38 is installed inside the mounting groove 23, the lifting groove 24 is opened on the inner side of both sides of the cutting table 21, and the limit rod 25 is welded to the inner side of the lifting groove 24.

[0032] In this embodiment: the cutting table 21 supports and limits the cutting groove 22, the mounting groove 23, and the lifting groove 24. The cutting groove 22 is located at the bottom of the cutting table 21, providing space for the cutting blade 28 to move downwards and preventing the blade from directly contacting the worktable 1 and causing damage. The mounting groove 23 is used to fix the trigger sensor 38, ensuring that it stably detects the material position and provides an accurate trigger signal for fixed-length cutting. The lifting groove 24 and the limiting rod 25 work together to limit the lifting trajectory of the support beam 26, so that the cutting blade 28 can move smoothly in the vertical direction. The support beam 26 can support and limit the electric cylinder 27 and the laser displacement sensor 37. The electric cylinder 27 drives the cutting blade 28 to move up and down, and the cutting blade 28 can cut the insulation material.

[0033] Specifically, such as Figure 4 , Figure 5 As shown, the support beam 26 is welded to the top of the cutting table 21, the electric cylinder 27 is installed on the top of the inner side of the support beam 26, the laser displacement sensor 37 is installed on the front side of the top of the inner side of the support beam 26, and the cutting blade 28 is installed on the telescopic end at the bottom of the electric cylinder 27.

[0034] Specifically, such as Figure 3 As shown, a reinforcing ring 4 is fixedly connected to the telescopic end at the bottom of the electric cylinder 27, and the surface of the reinforcing ring 4 is coated with an anti-corrosion coating.

[0035] In this embodiment: by setting a reinforcing ring 4, a rigid connection structure is formed with the cutting blade 28, which effectively disperses the impact force during cutting and prevents the connection between the electric cylinder 27 and the cutting blade 28 from loosening or breaking due to frequent stress. By setting an anti-corrosion coating, it can resist the corrosion of chemicals and moisture that may come into contact with the insulation material during processing, and extend the service life of the reinforcing ring 4.

[0036] Specifically, such as Figure 1 As shown, two reinforcing rods 5 are welded to both sides of the cutting blade 28. Three pressure plates 6 are welded to the surface of the reinforcing rods 5. The bottom of the pressure plates 6 is engraved with anti-slip texture.

[0037] Specifically, such as Figure 1As shown, slide rods 7 are welded to both sides of the lower pressure plate 6, and four limiting plates 8 are welded to both sides of the top of the worktable 1. A sliding groove 9 is provided on the inner side of the limiting plate 8. The side of the slide rod 7 away from the lower pressure plate 6 is slidably connected to the inner side of the sliding groove 9. A limiting ring 10 is welded to the side of the slide rod 7 away from the lower pressure plate 6.

[0038] In this embodiment: by setting the reinforcing rod 5, the lower pressure plate 6 can be supported and limited; by setting the lower pressure plate 6, the insulation material can be pressed and fixed; by setting the anti-slip texture, the friction with the material surface is increased; by setting the sliding rod 7, the vertical movement of the lower pressure plate 6 is guided and supported, ensuring that the lower pressure plate 6 descends smoothly during the pressing of the material, avoiding tilting or jamming; by setting the limiting plate 8, the sliding groove 9 can be supported and limited; by setting the sliding groove 9, the movement trajectory of the lower pressure plate 6 is constrained; by setting the limiting ring 10, the sliding rod 7 is prevented from coming out of the sliding groove 9.

[0039] Working Principle: First, the operator places the insulation material onto the conveyor rollers 32. Then, the operator starts the servo motor 35 via the PLC controller 39. The servo motor 35 transmits power synchronously to each conveyor roller 32 through the connecting wheel 33 and the connecting belt 34, driving the insulation material to be conveyed backward at a uniform speed. At the same time, the absolute encoder 36 measures the rotation angle of the conveyor rollers 32 in real time and calculates the material conveying distance based on the roller circumference, providing basic data for fixed-length measurement. Next, when the front end of the insulation material touches the trigger sensor 38, the trigger sensor 38 immediately transmits a signal to the PLC controller 39. The PLC controller 39 then controls the laser displacement sensor 37 to start, beginning to detect the length of the passing insulation material and assisting the absolute encoder 36 in correcting measurement errors to ensure the accuracy of length measurement. Then, when the PLC controller 39 calculates the length of the insulation material according to the absolute encoder... Based on the data from the encoder 36 and the laser displacement sensor 37, when it is determined that the insulation material has been conveyed to the preset cutting length, a command is immediately sent to the servo motor 35 to stop the material conveying. At the same time, the PLC controls the machine to send a signal to the electric cylinder 27. Then, the electric cylinder 27 drives the cutting blade 28 to move downward. During the movement, the lifting groove 24 and the limit rod 25 restrict the lifting trajectory of the support beam 26 to ensure that the cutting blade 28 moves vertically and smoothly downward. At the same time, the lower pressure plate 6 on the reinforcing rods 5 on both sides of the cutting blade 28 moves downward synchronously to press the insulation material tightly and prevent the material from shifting during cutting. Finally, the cutting blade 28 reaches the cutting groove 22 to complete the cutting of the insulation material. After the cutting is completed, the electric cylinder 27 drives the cutting blade 28 and the lower pressure plate 6 to rise and reset. The servo motor 35 starts again to convey the next section of insulation material and repeats the above fixed-length cutting process to realize the automated fixed-length cutting of insulation material.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
