Description

Technical Field

[0001] This utility model relates to the technical field of sound-absorbing cotton stretching equipment, specifically to a stretching equipment for producing composite fiber sound-absorbing cotton. Background Technology

[0002] Sound-absorbing cotton is a man-made inorganic fiber made primarily from natural minerals such as quartz sand, limestone, and dolomite, combined with chemical raw materials like soda ash and borax to form a glass-like structure. In its molten state, it is blown and spun into fine, flocculent fibers using external force. These fibers are three-dimensionally intertwined, creating numerous tiny gaps between them. During the production of sound-absorbing cotton, its tensile properties need to be tested.

[0003] The specification of a stretching device for producing composite fiber sound-absorbing cotton (publication number CN217901389U) mentions that "electric hydraulic push rods are installed at the four corners of the upper surface of the base, a support plate is set above the base, the output end of the electric hydraulic push rod is fixedly connected to the lower surface of the support plate, and a stretching mechanism is connected to the upper surface of the support plate. The stretching mechanism includes a rectangular slide frame, a motor, a lead screw, a slider, an L-shaped frame plate, an electric push rod, and a pressure block. A rectangular slide frame is fixedly connected to the upper surface of the support plate, a motor is installed on one side of the rectangular slide frame, and the output end of the motor passes through the side of the rectangular slide frame and is fixedly connected to the lead screw through a coupling." However, the stretching device in the prior art uses a cylinder head to clamp and fix the composite fiber sound-absorbing cotton. The clamping area is small and it is not suitable for stretching composite fiber sound-absorbing cotton of different widths. It is easy for the composite fiber sound-absorbing cotton to curl on the side during the stretching process, affecting the neatness and stability of the stretching, and is not safe, stable, or practical. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a stretching device for producing composite fiber sound-absorbing cotton is provided. This device addresses the problem that existing stretching devices use cylinder heads to clamp and fix composite fiber sound-absorbing cotton, resulting in a small clamping area that is unsuitable for stretching composite fiber sound-absorbing cotton of different widths. This also easily leads to the composite fiber sound-absorbing cotton curling on the sides during the stretching process, affecting the neatness and stability of the stretching, and making it unsafe, unstable, and impractical.

[0005] To achieve the above objectives, a stretching device for producing composite fiber sound-absorbing cotton is provided, comprising a left clamping stretching structure, a stretching table, and a right clamping stretching structure. A first connecting plate is fixed to both the left and right sides of the left clamping stretching structure, and a linear guide rail is fixed to the outer end of each first connecting plate. A second connecting plate is fixed to the rear end of the first connecting plate, and a rear fixing sleeve is fixed to the inner side of the second connecting plate. A first stroke-limiting telescopic cylinder is housed within the rear fixing sleeve, and a rear fixing frame is fixed to the front end of the first stroke-limiting telescopic cylinder. The left clamping stretching structure is fixed to the front end of the rear fixing frame on the left side of the stretching table, and the right clamping stretching structure is fixed to the front end of the rear fixing frame on the right side of the stretching table.

[0006] Furthermore, both ends of the left clamping and stretching structure are fixed with sliders, and the sliders are slidably connected to the linear guide rail, and the left clamping and stretching structure can move horizontally left and right.

[0007] Furthermore, multiple sets of second stroke limiting telescopic cylinders are fitted on both the left and right sides of the left clamping and stretching structure, and the upper ends of the second stroke limiting telescopic cylinders are fixed inside the upper mounting frame. Multiple sets of upper clamping wheels are fitted between the two sets of upper mounting frames on the left and right sides.

[0008] Furthermore, both the left and right sides of the upper end face of the left clamping and stretching structure are fixed with lower mounting brackets, and lower clamping wheels are sleeved between the two sets of lower mounting brackets on the left and right sides, and the upper clamping wheels and lower clamping wheels are aligned vertically.

[0009] Furthermore, anti-slip strips are provided on the outer ring surfaces of the upper and lower clamping wheels, and the anti-slip strips are made of silicone rubber.

[0010] Furthermore, the left clamping and stretching structure and the right clamping and stretching structure are symmetrical about the center line of the left clamping and stretching structure, and the right clamping and stretching structure and the left clamping and stretching structure have the same structural configuration.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses the telescopic movement of the first stroke limit telescopic cylinder to push the left clamping and stretching structure to move left and right on the linear guide rail, so as to be suitable for stretching composite fiber sound-absorbing cotton of different lengths and sizes, making it more flexible and practical.

[0013] 2. This utility model utilizes the appropriate extension and retraction of the second stroke limit telescopic cylinder to drive the upper clamping wheel to move up and down, so as to move the upper clamping wheel down, thereby stably pressing the upper clamping wheel on the lower clamping wheel, and the upper and lower clamping wheels are aligned vertically and horizontally, with equal lengths, resulting in a horizontal, neat, and stable clamping.

[0014] 3. The upper and lower clamping wheels of this utility model are equipped with anti-slip strips, which makes the composite fiber sound-absorbing cotton clamped between the upper and lower clamping wheels not only horizontal and straight, but also safe and slip-resistant, making its stretching operation safer, more stable and reliable.

[0015] 4. In this utility model, the left clamping and stretching structure and the right clamping and stretching structure are opposite each other, which makes it convenient to use the left clamping and stretching structure to clamp the left side of the composite fiber sound-absorbing cotton, and the right clamping and stretching structure to clamp the right side of the composite fiber sound-absorbing cotton. This allows for a more stable and quicker stretching process after the composite fiber sound-absorbing cotton is clamped in a left-right alignment. Attached Figure Description

[0024] Reference Figures 1 to 4 As shown, this utility model provides a stretching device for producing composite fiber sound-absorbing cotton, including a left clamping stretching structure 1, a stretching table 2, and a right clamping stretching structure 3. A first connecting plate 20 is fixed to both the left and right sides of the left clamping stretching structure 1, and a linear guide rail 21 is fixed to the outer end of the first connecting plate 20. A second connecting plate 22 is fixed to the rear end of the first connecting plate 20, and a rear fixing sleeve 23 is fixed to the inner side of the second connecting plate 22. A first stroke limiting telescopic cylinder 24 is fitted inside the rear fixing sleeve 23, and a rear fixing frame 25 is fixed to the front end of the first stroke limiting telescopic cylinder 24. The left clamping stretching structure 1 is fixed to the front end of the rear fixing frame 25 on the left side of the stretching table 2, and the right clamping stretching structure 3 is fixed to the front end of the rear fixing frame 25 on the right side of the stretching table 2.

[0025] In this embodiment, both ends of the left clamping and stretching structure 1 are fixed with sliders 10, and the sliders 10 are slidably connected to the linear guide rail 21. The left clamping and stretching structure 1 can move horizontally left and right.

[0026] As a preferred embodiment, the present invention uses the telescopic movement of the first stroke limiting telescopic cylinder 24 to push the left clamping and stretching structure 1 to move left and right on the linear guide rail 21, so as to be suitable for stretching composite fiber sound-absorbing cotton of different lengths and sizes, making it more flexible and practical.

[0027] In this embodiment, multiple sets of second stroke limiting telescopic cylinders 13 are fitted on both the left and right sides of the left clamping and stretching structure 1, and the upper ends of the second stroke limiting telescopic cylinders 13 are fixed inside the upper mounting bracket 16. Multiple sets of upper clamping wheels 15 are fitted between the two sets of upper mounting brackets 16 on the left and right sides. Lower mounting brackets 11 are fixed on both the left and right sides of the upper end face of the left clamping and stretching structure 1, and lower clamping wheels 12 are fitted between the two sets of lower mounting brackets 11 on the left and right sides. The upper clamping wheels 15 and the lower clamping wheels 12 are aligned vertically.

[0028] As a preferred embodiment, the present invention utilizes the appropriate extension and retraction of the second stroke limit telescopic cylinder 13 to drive the upper clamping wheel 15 to move up and down, so as to move the upper clamping wheel 15 downward, thereby stably pressing the upper clamping wheel 15 onto the lower clamping wheel 12, and the upper clamping wheel 15 and the lower clamping wheel 12 are aligned vertically and horizontally, with equal lengths, and the clamping is horizontal, neat and stable.

[0029] In this embodiment, anti-slip strips 14 are provided on the outer ring surfaces of the upper clamping wheel 15 and the lower clamping wheel 12, and the anti-slip strips 14 are made of silicone rubber.

[0030] As a preferred embodiment, both the upper clamping wheel 15 and the lower clamping wheel 12 of this utility model are provided with anti-slip strips 14, so that the composite fiber sound-absorbing cotton clamped between the upper clamping wheel 15 and the lower clamping wheel 12 is not only horizontal and straight, but also safe and slip-resistant, making its stretching operation safer, more stable and reliable.

[0032] As a preferred embodiment, the left clamping and stretching structure 1 and the right clamping and stretching structure 3 are positioned opposite each other in this utility model. This allows the left clamping and stretching structure 1 to clamp the left side of the composite fiber sound-absorbing cotton, while the right clamping and stretching structure 3 clamps the right side of the composite fiber sound-absorbing cotton. This ensures that the composite fiber sound-absorbing cotton is stably clamped and stretched after being aligned left and right, making the process faster, more stable, and more convenient.

[0033] This invention effectively solves the problems of existing stretching equipment that uses cylinder heads to clamp and fix composite fiber sound-absorbing cotton. The clamping area is small and unsuitable for stretching composite fiber sound-absorbing cotton of different widths, easily causing the cotton to curl on the sides during stretching, affecting the neatness and stability of the stretching process, and making it unsafe, unstable, and impractical. This invention is suitable for stretching composite fiber sound-absorbing cotton of different sizes, with a safe, stable, and non-slip clamping mechanism, helping to ensure the neatness and stability of the composite fiber sound-absorbing cotton during the stretching process, making it more efficient, stable, and practical.
