[0002] Fiberglass chopped strands are a high-performance inorganic non-metallic material with advantages such as good insulation, strong heat resistance, and good corrosion resistance. They are widely used in many fields such as construction, electronics, automobiles, and aerospace. With the continuous development of these industries, the demand for fiberglass chopped strands is also increasing, and higher requirements are being placed on their cutting precision and quality.

[0003] In the early days, the cutting of chopped glass fibers mainly relied on manual operation, using simple tools such as scissors. This method was inefficient, the cutting accuracy was difficult to guarantee, and the workers were physically exhausted and easily injured by the glass fibers, posing certain safety hazards. For chopped fibers with different length requirements, the adjustment of traditional equipment was often not flexible enough, requiring a lot of time to readjust and reposition, which reduced production efficiency.

[0004] Therefore, this utility model provides a glass fiber chopped strand cutting and positioning device to solve the above problems. Utility Model Content

[0025] 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.

[0026] This utility model provides a glass fiber chopped strand cutting and positioning device, such as... Figures 1 to 5 As shown, the system includes a base 1. An idler wheel bracket 2 is fixedly mounted on one side of the upper surface of the base 1 by bolts. An extension end is provided on one side of the idler wheel bracket 2. A moving groove 201 is opened on the surface of the extension end of the idler wheel bracket 2. A fastening nut 202 is movably connected to the inner arc surface of the moving groove 201. A drive shaft is movably connected to the back of the idler wheel bracket 2 by a rotating shaft. A synchronous wheel 3 is fixedly mounted on the drive shaft on the back of the idler wheel bracket 2. A synchronous belt 4 is movably sleeved on the outer arc surface of the synchronous wheel 3. A guide groove 101 is opened on the upper surface of the base 1. Both sides of the upper surface of the guide groove 101 are provided with clearance grooves A102.

[0027] The glass fiber is precisely placed at a specific position between the pressure block 7 and the guide groove 101. At this time, the protrusion 701 at the lower end applies stable and appropriate pressure to the glass fiber, making it fit tightly against the bottom of the guide groove 101, thereby achieving effective sturdiness of the glass fiber fabric. This sturdiness is crucial for subsequent cutting operations, as it provides a more accurate positioning reference for the cutter, greatly improving the accuracy and stability of cutting. The pressure block 7 is cleverly installed on the top of the guide groove 101, and its protrusion 701 can extend into the guide groove 101 just right, forming a narrow gap with the bottom surface of the guide groove 101, allowing the glass fiber to pass through smoothly. The width of this gap is precisely set to be equal to the thickness of conventional glass fiber. In this way, the glass fiber can pass through the gap smoothly in an absolutely flat posture, effectively avoiding cutting errors caused by fiber bending or twisting.

[0028] A pressure block 7 is slidably engaged with the bottom of the inner arc surface of the guide groove 101. A protrusion 701 is provided in the middle of the lower surface of the pressure block 7, and the lower surface of the protrusion 701 is slidably engaged with the guide groove 101. A clearance groove B702 is provided in the middle of the upper surface of the pressure block 7, corresponding to clearance groove A102. A middle cavity is provided in the middle of the base 1. A fixing member 8 is slidably connected to the upper surface of the pressure block 7. There are two synchronous pulleys 3, and the two synchronous pulleys 3 are movably connected to the two idler pulley brackets 2 via a rotating shaft. The synchronous belt 4... The lower surface is fixedly connected to the fixing member 8. A fixing block 801 is connected to one side of the fixing member 8. A fixing groove 802 is provided between the fixing block 801 and the fixing member 8. A support rod 803 is fixedly installed on the inner side wall of the fixing groove 802. The fixing member 8 and the fixing block 801 are connected by the support rod 803. A cutting blade 9 is movably sleeved on the outer arc surface of the support rod 803. A hook groove 901 is opened on one side of the cutting blade 9. The hook groove 901 is movably sleeved on the support rod 803. One end of the cutting blade 9 is connected through to the relief groove B702.

[0029] In addition, a clearance groove B702 is carefully machined on the pressure block 7, running from top to bottom. The cutting blade 9 is cleverly designed to precisely pass through the clearance groove B702 from the top of the pressure block 7 and extend to the bottom surface of the guide groove 101. At the same time, a clearance groove A102 is also provided on the bottom surface of the guide groove 101. The main function of the clearance groove A102 is to provide sufficient clearance space for the cutting blade 9 during movement, ensuring that the cutting blade 9 can pass through the clearance groove B702 without obstruction and smoothly penetrate the bottom surface of the guide groove 101. The movement trajectory of the cutting blade is further optimized and stabilized, minimizing the problem of reduced cutting accuracy caused by cutting blade movement deviation. At the same time, it also provides a solid guarantee that the precisely positioned glass fiber can maintain a stable state during the cutting process, thereby significantly improving the cutting accuracy of the glass fiber.

[0030] Throughout the operation, the precise movement control of the cutting blade 9 is achieved through the coordinated action of the stepper motor and the synchronous pulley 3. The stepper motor, as the power source, has its output shaft tightly connected to the synchronous pulley 3. When the stepper motor starts running, it drives the synchronous pulley 3 to rotate stably. Since the synchronous belt 4 is tightly fitted onto the surface of the synchronous pulley 3, the rotation of the synchronous pulley 3 drives the synchronous belt 4 to rotate synchronously. A reliable connection exists between the fixing member 8 and the synchronous belt 4. Therefore, as the synchronous belt 4 rotates, the fixing member 8 moves stably along a specific path on the pressure block 7. Notably, the cutting blade 9 and the fixing member 8 are connected as a single unit. Therefore, during the movement of the fixing member 8, the cutting blade 9 also moves smoothly and precisely within the corresponding slot. This ensures that the cutting blade 9 operates strictly according to the preset trajectory and speed when cutting glass fiber, effectively guaranteeing the accuracy and efficiency of the cutting action and ensuring stable glass fiber cutting.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
