Description

Technical Field

[0001] This utility model relates to the field of fur processing technology, specifically to a fur processing stretching machine that facilitates fixed-length processing. Background Technology

[0002] Animal fur, tanned with the hair still attached, is used as a material for clothing. Common types include fox, mink, sheepskin, and wolfskin. Fur clothing is one of the high-end winter garments for women, giving them an elegant and luxurious appearance. During the processing of fur, it is necessary to stretch the fur to a specific length. However, during the stretching process, the width can easily become narrower. A search revealed a patent with publication number CN207811769U that discloses an automatic and efficient fur stretching machine. This machine uses a width fixing plate that is movably installed inside and outside the width adjusting rod, with an anti-fall net riveted to the bottom of the width fixing plate. This ensures that the width of the fur remains constant during stretching and prevents the fur from falling into the machine. However, even with the width fixing plate fixed, the width can still become narrower during the stretching process. To address this, a retractable width-fixing mechanism with multi-point clamping components is designed. This allows the multi-point clamping components to be laterally distributed during the stretching process, ensuring the uniformity of the stretched width of the fur and facilitating the stretching of the fur into a fur stretching machine that is convenient for fixed-length processing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fur processing stretching machine that facilitates fixed-length processing. It features a telescopic width-fixing mechanism with multi-point clamping components, which allows the multi-point clamping components to be laterally dispersed during the stretching process, ensuring the uniformity of the fur's stretched width.

[0005] (2) Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fur processing stretching machine that facilitates fixed-length processing, comprising a stretching frame, wherein two sets of left-right symmetrical and relative feeding clamping mechanisms are provided on the stretching frame, and a telescopic width-fixing mechanism with multi-point clamping components is symmetrically arranged on the front and rear sides between the two long-side clamping mechanisms. The telescopic width-fixing mechanism includes a central shaft that slides and guides the outer side of the two long-side clamping mechanisms, and the multi-point clamping components include multiple sets of width-fixing clamps horizontally spaced on the central shaft, and a spring sleeved on the central shaft connects two adjacent sets of width-fixing clamps.

[0007] Preferably, the width-fixing clamp includes two symmetrical, tangent clamping bars that are rotatably and slidingly engaged around a central axis. Each clamping bar has a fur patch and a rear adjusting ring on both sides. It also includes two offset shafts that are rotatably and slidingly engaged with the two rear adjusting rings. The ends of the two offset shafts also include a spacing adjustment component for adjusting the distance between the two offset shafts. The two clamping bars at the middle positions of the two adjacent width-fixing clamps on both sides of the spring are rotatably connected.

[0008] Preferably, the spacing adjustment assembly includes an adjustment frame, on which a side adjustment bidirectional screw is rotatably connected. A sliding adjustment slider that slides in a guide-sliding fit with the adjustment frame is symmetrically threaded onto the side adjustment bidirectional screw. A side adjustment drive is fixedly installed at one end of the sliding adjustment slider. The two offset shafts are respectively fixedly connected to the two sliding adjustment sliders. The spacing adjustment assembly is located on the outside of the elongated frame, and the elongated frame has adjustment through holes for the side adjustment drive that are adapted to the two offset shafts.

[0009] Preferably, the long-side clamping mechanism includes a U-shaped clamp that is horizontally directed towards the center. The top of the U-shaped clamp is slidably fitted with a clamping strip with multiple anti-slip tips at the bottom. A drive cylinder for driving the clamping strip to rise and fall is fixedly installed on the top of the U-shaped clamp.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, this utility model provides a fur processing stretching machine that facilitates fixed-length processing, and has the following beneficial effects:

[0014] This fur processing and stretching machine, which facilitates fixed-length processing, uses two long-side clamping mechanisms to clamp the two stretching sides. These clamping mechanisms then move laterally to stretch the fur. A telescopic width-fixing mechanism with multi-point clamping components allows for multi-point clamping of the width sides. During stretching, these multi-point clamping points disperse, ensuring consistent width at multiple points and uniform overall fur width. The cooperation between the central shaft and the two long-side positioning clamping mechanisms provides overall stability to the telescopic width-fixing mechanism and the long-side clamping mechanisms. This also ensures that the telescopic width-fixing mechanism remains positioned between the two long-side clamping mechanisms during retraction. The telescopic width-fixing mechanism with multi-point clamping components allows for lateral dispersion of the clamping components during stretching, guaranteeing uniform fur stretching width.

Detailed Implementation

[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] Example:

[0026] Please see Figure 1-8 A fur processing stretching machine for easy fixed-length processing includes a stretching frame 1. The stretching frame 1 is provided with two sets of left-right symmetrical long-side clamping mechanisms that can move relative to each other. The front and rear sides of the two long-side clamping mechanisms are symmetrically provided with a telescopic width-fixing mechanism with multi-point clamping components. The telescopic width-fixing mechanism includes a central shaft 2 that slides and guides the outer side of the two long-side clamping mechanisms. The multi-point clamping components include multiple sets of width-fixing clamps that are horizontally spaced and sleeved on the central shaft 2. A spring 6 sleeved on the central shaft 2 connects two adjacent sets of width-fixing clamps.

[0027] Specifically, the width clamp includes two symmetrical tangent clamping strips 14 that rotate and slide around the central axis 2. Fur pieces 3 and rear adjusting rings 4 are respectively provided on both sides of the clamping strips 14. It also includes two offset shafts 5 that rotate and slide with the two rear adjusting rings 4 respectively. The ends of the two offset shafts 5 also include a spacing adjustment component for adjusting the distance between the two offset shafts 5. The two clamping strips 14 at the middle position of the two adjacent width clamps on both sides of the spring 6 are rotatably connected. The distance between the two offset shafts 5 can be easily adjusted by the spacing adjustment component, so that the two clamping strips 14 can be clamped in the middle, so that the two fur pieces 3 can clamp a point on the wide side of the fur. With the setting of the spring 6, multiple width clamps can be contracted after contact stretching.

[0028] Specifically, the spacing adjustment component includes an adjustment frame 8, on which a side adjustment bidirectional screw 10 is rotatably connected. A sliding adjustment slider 9, which slides in a guide-sliding engagement with the adjustment frame 8, is symmetrically threaded onto the side adjustment bidirectional screw 10. A side adjustment drive component 11 is fixedly installed at one end of the sliding adjustment slider 9. Two offset shafts 5 are respectively fixedly connected to the two sliding adjustment sliders 9. The spacing adjustment component is located on the outside of the elongated frame 1, and the elongated frame 1 has adjustment through holes for the side adjustment drive component 11 that are adapted to the two offset shafts 5. Further, the side adjustment drive component 11 can be a knob or a motor. The side adjustment drive component 11 drives the side adjustment bidirectional screw 10 to rotate clockwise or counterclockwise, thereby moving the two sliding adjustment sliders 9 towards the center or to the sides, which in turn moves the two offset shafts 5 towards the center or to the sides, thus adjusting the distance between the two offset shafts 5, and consequently adjusting the width clamp for opening and closing operations.

[0029] Specifically, the long-side clamping mechanism includes a U-shaped clamp 12 horizontally positioned towards the center. Inside the U-shaped clamp 12, a clamping strip 14 with multiple anti-slip tips 15 at its bottom is slidably fitted at the top. A drive cylinder 13 is fixedly installed on the top of the U-shaped clamp 12 to drive the clamping strip 14 to rise and fall. Guide slides 7 are fixedly installed on both sides of the U-shaped clamp 12, which are slidably fitted with the off-axis 5 on the same side. The drive cylinder 13 facilitates the lifting and lowering of the clamping strip 14 with multiple anti-slip tips 15 at its bottom, thereby clamping the fur between the bottom of the clamping strip 14 and the bottom of the inner part of the U-shaped clamp 12. The multiple anti-slip tips 15 improve the stability of the fur clamping.

[0030] Specifically, it also includes a fixed-length feed drive mechanism adapted to the two sets of long-side clamping mechanisms. The fixed-length feed drive mechanism includes a U-shaped bracket 17 fixedly installed at the bottom of the elongation frame 1. An elongation adjustment bidirectional screw 19 is rotatably connected to the U-shaped bracket 17. Two connecting slide rods 18, which are horizontally guided and slidably engaged with the U-shaped bracket 17, are symmetrically threaded onto the elongation adjustment bidirectional screw 19. The connecting slide rods 18 and the U-shaped clamps 12 on the same side are fixedly connected by a fixed-length stretching slide rod 16 that is horizontally guided and slidably engaged with the elongation frame 1. It also includes an elongation drive component that drives the elongation adjustment bidirectional screw 19 to rotate. Through the elongation drive component, it is easy to drive the elongation adjustment bidirectional screw 19 to rotate clockwise or counterclockwise, thereby driving the two connecting slide rods 18 to move to the sides or to the middle, and simultaneously driving the U-shaped clamps 12 on both sides to move to the sides or to the middle. The setting of the fixed-length stretching slide rod 16 makes it easy to limit the elongation distance of the long-side clamping mechanism and ensure the fixed-length stretching of the fur.

[0031] Specifically, the elongation drive includes an elongation adjustment motor 20 fixedly mounted on the U-shaped bracket 17. The output shaft of the elongation adjustment motor 20 is connected to the elongation adjustment bidirectional screw 19 via a transmission assembly 21. Furthermore, the transmission assembly 21 can adopt a sprocket and chain or a synchronous belt and synchronous pulley transmission method, preferably a sprocket and chain transmission method. When the elongation adjustment motor 20 is started, the output shaft of the elongation adjustment motor 20 rotates clockwise or counterclockwise. Through the transmission of the transmission assembly 21, the elongation adjustment bidirectional screw 19 can be driven to rotate clockwise or counterclockwise.

[0032] In use, the two long sides are clamped by two long-side clamping mechanisms, and then multiple width-fixing clamps on both sides clamp the wide sides. Then, the two long-side clamping mechanisms are moved to both sides and stretched to a fixed length. The fur is stretched, and the multiple width-fixing clamps on both sides are dispersed accordingly, so that the width at multiple points is consistent and the overall fur width is relatively uniform. Then, the fur is removed from the long-side clamping mechanisms and the multiple width-fixing clamps on both sides. Then, the two long-side clamping mechanisms are fed to the middle and returned to the initial state. Then, the above operation is repeated.
