Description

Technical Field

[0001] This utility model relates to the field of thin glass fiber mat production equipment, and in particular to a thin glass fiber cutting device with adjustable width. Background Technology

[0002] Thin fiberglass mats need to be cut into products that meet the width requirements during the production process. Existing thin fiberglass mat cutting devices generally adjust the cutting width by using a cutter shaft, and the entire machine needs to be stopped to replace it, which is time-consuming, labor-intensive, and very inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a thin glass fiber cutting device with adjustable width that allows for adjustment of the cutting width without stopping the machine and facilitates easy replacement of the cutting blade.

[0004] The technical solution to achieve the purpose of this utility model is as follows:

[0005] An adjustable-width thin glass fiber cutting device includes a first frame and a second frame arranged in parallel. A screw and multiple guide rods are disposed between the first frame and the second frame. A first mounting plate is fixed on the first frame, and a second mounting plate is fixed on the second frame. A motor with a rotating shaft is fixed on the first mounting plate. One end of the screw is fixedly connected to the rotating shaft, and the other end is rotatably connected to the second mounting plate. One end of each guide rod is fixedly connected to the first mounting plate, and the other end is fixedly connected to the second mounting plate. The screw has a first threaded segment and a second threaded segment with opposite helical directions. A first slider is fitted onto the first threaded segment, and a second slider is fitted onto the second threaded segment. Both the first and second sliders are mounted on the guide rods. The first and second sliders are slidably coupled with the guide rod. Both the first and second sliders are fixed with a first connecting rod and a second connecting rod. The first connecting rod is higher than the second connecting rod. A first rotating rod is fitted on the first connecting rod and is rotatably connected to the first connecting rod. A linear drive assembly with a telescopic shaft is fixed on the first rotating rod. A second rotating rod is fitted on the second connecting rod and is rotatably connected to the second connecting rod. A third connecting rod and a fourth connecting rod are fixed on the second rotating rod. The telescopic shaft is fitted on the third connecting rod and is rotatably connected to the third connecting rod. A cutting blade is fixed on the fourth connecting rod. A transition roller is provided below the cutting blade. The two ends of the transition roller are rotatably connected to the first frame and the second frame, respectively. The guide rod is provided with a scale.

[0006] With the above structure, when the cutting width needs to be adjusted, the telescopic shaft is retracted by the linear drive assembly, thereby rotating the second rotating rod to lift the cutting blade. The screw is driven by the motor to rotate, causing the sliders to move towards or away from each other, thereby quickly adjusting the distance between the cutting blades and realizing the adjustment of the cutting width. The cutting width and the adjusted size can be clearly seen through the scale on the guide rod. After the width is fully adjusted, the cutting blade is lowered back to its original position by the linear drive assembly. When the cutting blade needs to be replaced, it can be quickly replaced by lifting the cutting blade by the linear drive assembly. This utility model can quickly adjust the cutting width and can also quickly replace the cutting blade without stopping the machine, which is convenient and fast.

[0007] Preferably, to prevent the cutting blade from descending too low, a baffle is fixed on both the first and second sliders. The baffle is located below the first rotating rod, and a contact switch is installed on the baffle. When the first rotating rod drives the cutting blade to descend, the linear drive assembly stops working after the first rotating rod contacts the contact switch, and the first rotating rod remains stationary.

[0008] Preferably, for ease of control of the linear drive assembly, the linear drive assembly is a cylinder.

[0009] Preferably, in order to facilitate the assembly and disassembly of the cutting blade, two locking nuts are fitted on the fourth connecting rod, and the two locking nuts are respectively fitted on both sides of the cutting blade and clamp the cutting blade. Attached Figure Description

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0012] Figure 2 This is a schematic diagram of the assembly of the first slider and the second slider of this utility model. Detailed Implementation

[0013] like Figure 1 and Figure 2As shown, this utility model discloses a thin glass fiber cutting device with adjustable width, comprising a first frame 1 and a second frame 2 arranged in parallel. A screw 3 and multiple guide rods 4 are arranged between the first frame and the second frame. A first mounting plate 5 is fixed on the first frame, and a second mounting plate 6 is fixed on the second frame. A motor 7 is fixed on the first mounting plate, and the motor has a rotating shaft. One end of the screw is fixedly connected to the rotating shaft, and the other end is rotatably connected to the second mounting plate. One end of the guide rod is fixedly connected to the first mounting plate, and the other end is fixedly connected to the second mounting plate. The screw is provided with a first threaded section 8 and a second threaded section 9 with opposite helical directions. A first slider 10 is fitted onto the first threaded section, and a second slider 11 is fitted onto the second threaded section. Both the first and second sliders are fitted onto the guide rods and slide in cooperation with the guide rods. Both the first and second sliders are fixed with... A first connecting rod 12 and a second connecting rod 13 are connected, with the first connecting rod being higher than the second connecting rod. A first rotating rod 14, rotatably connected to the first connecting rod, is fitted on the first connecting rod. A cylinder 15 with a telescopic shaft 16 is fixed on the first rotating rod. A second rotating rod 17, rotatably connected to the second connecting rod, is fitted on the second rotating rod. A third connecting rod 18 and a fourth connecting rod 19 are fixed on the second rotating rod. The telescopic shaft is fitted on the third connecting rod and rotatably connected to it. A cutting blade 20 is fixed on the fourth connecting rod. Two locking nuts 21, threadedly connected to the fourth connecting rod, are fitted on the fourth connecting rod. The two locking nuts are fitted on both sides of the cutting blade and clamp it. A transition roller 22 is provided below the cutting blade. The two ends of the transition roller are rotatably connected to the first frame and the second frame, respectively. A scale is provided on the guide rod.

[0014] In some embodiments, such as Figure 1 As shown, both the first slider and the second slider are fixed with baffles 23, which are located below the first rotating rod, and contact switches 24 are installed on the baffles.

[0015] With the above structure, when the cutting width needs to be adjusted, the telescopic shaft is retracted by the linear drive assembly, thereby rotating the second rotating rod to lift the cutting blade. The screw is driven by the motor to rotate, causing the sliders to move towards or away from each other, thereby quickly adjusting the distance between the cutting blades and realizing the adjustment of the cutting width. The cutting width and the adjusted size can be clearly seen through the scale on the guide rod. After the width is fully adjusted, the cutting blade is lowered back to its original position by the linear drive assembly. When the cutting blade needs to be replaced, it can be quickly replaced by lifting the cutting blade by the linear drive assembly. This utility model can quickly adjust the cutting width and can also quickly replace the cutting blade without stopping the machine, which is convenient and fast.
