Description

Technical Field

[0001] The utility model relates to the technical field of stenter machines, in particular to an anti-curling material receiving structure and a stenter machine. Background Art

[0002] The stenter machine is mainly used in the post-treatment process of textiles. By stretching and shaping, the fabric size is stabilized and the form is beautiful. The anti-curling material receiving structure is a key component to ensure the quality of the finished product in this process. It often dynamically adjusts the position and tension of the installation roller to ensure that the material remains flat during the winding process, reducing curling and wrinkling phenomena.

[0003] For example, a product inspection machine anti-curling material receiving device disclosed in Chinese Patent Publication No. CN216335553U. When inspecting the material, the anti-curling mechanism can be adjusted to perform longitudinal pressing on the material. Cooperating with the elastically moving sliding block, elastic pressing can be effectively carried out, so that the material is straightened under the longitudinal pressure, and the material is wound around the roller shaft more evenly, avoiding the phenomenon of curling and offset of the material, and effectively improving the quality of the wound roll. However, when adjusting the anti-curling mechanism of this existing device, it often can only be preset for materials with a specific width, lacking flexibility and unable to dynamically adjust according to the actual width of the material, resulting in possible curling of the material during the winding process due to width mismatch. And when driving the pressing mechanism (or roller shaft) to rotate, due to the lack of an anti-reverse mechanism, in the event of an accident, the material may curl or offset due to reverse rotation, resulting in material wrinkling. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an anti-curling material receiving structure and a stenter machine, which can flexibly adapt to materials with different widths and thicknesses by adjusting the length of the installation roller and the distance between two groups of installation rollers.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An anti-curling material receiving structure, including a base and a stenter machine main body on its top. A support platform is fixed outside the stenter machine main body. Two groups of installation rollers for winding and limiting the material are arranged on the top of the base.

[0006] Each group of installation rollers includes a first roller shaft and a second roller shaft.

[0007] The second length adjustment assembly includes a fixed plate arranged on the top of the support platform, a connecting sleeve is arranged outside the fixed plate, a screw is threadedly connected in the connecting sleeve, a movable plate is threadedly connected to the screw, and the mounting roller is arranged in the movable plate and the fixed plate.

[0008] Preferably, the first length adjustment assembly includes an assembly threaded rod disposed outside the second roller shaft and a first assembly groove opened in the second roller shaft.

[0009] Preferably, the first length adjustment component further comprises a second assembly groove provided in the first roller shaft, and the assembly threaded rod can be threadedly connected with the second assembly groove.

[0010] Preferably, the second length adjustment assembly further comprises a guide rod disposed outside the fixed plate, and a through hole for the guide rod to pass through is provided in the movable plate.

[0011] Preferably, a spacing adjustment component for adjusting the position of the group of installation rollers is arranged outside one group of the installation rollers, and the spacing adjustment component includes a first connection frame arranged at the top of the movable plate and a second connection frame arranged at the top of the fixed plate, an electric telescopic rod is fixed at the top of the first connection frame, and a slider is arranged at the output end of the electric telescopic rod and the second connection frame.

[0012] Preferably, both of the two sliders are rotatably connected to the second roller.

[0013] Preferably, a driving anti-reversal assembly for driving the other group of installation rollers is arranged outside the other group of installation rollers, and the driving anti-reversal assembly includes a driving motor arranged outside the fixed plate, and the output shaft of the driving motor is connected to the outside of the group of installation rollers through transmission, and a ratchet is arranged outside the side of the group of installation rollers away from the output shaft of the driving motor, and a third connecting frame is arranged outside the ratchet, and a ratchet pawl that can mesh with the ratchet is arranged in the third connecting frame.

[0016] Compared with the prior art, the utility model provides an anti-curling material collection structure and a stenter setting machine, which has the following beneficial effects:

[0017] 1. The anti-curling material receiving structure and the stentering machine can flexibly adapt to materials of different widths by adjusting the length of the installation roller. This design ensures an exact match between the width of the installation roller and that of the material, thus providing uniform support during material transmission. Due to the full contact between the installation roller and the outer surface of the material, it effectively prevents the material from curling and wrinkling due to lack of support, ensuring the flatness of the material during the stentering process;

[0018] 2. The anti-curling material receiving structure and the stentering machine not only allow the adjustment of the length of the installation roller, but also can precisely control the distance between two groups of installation rollers to adapt to materials of different thicknesses. Driven by the electric telescopic rod, the overall position of the installation roller can be flexibly adjusted to ensure that the distance between the two groups of installation rollers conforms to the thickness of the material. This distance control not only enhances the stability of material transmission, but also further prevents the curling of the material due to improper distance. At the same time, the one-way meshing design of the ratchet and pawl ensures that the installation roller will not reverse during material transmission, further improving the stability of material transmission and the anti-wrinkling effect.

Detailed implementation mode

[0028] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation modes.

[0029] Example 1: Please refer to Figures 1 - 6 , the present invention provides a technical solution: an anti-curling winding structure, including a base 1 and a main body of the stenter 2 on its top. A support table 3 is fixed outside the main body of the stenter 2, and two groups of mounting rollers 4 for winding and limiting the material are arranged on the top of the base 1.

[0030] Each group of mounting rollers 4 includes a first roller shaft 41 and a second roller shaft 42. A first length adjustment component 5 for adjusting the total length of the first roller shaft 41 and the second roller shaft 42 is arranged between the first roller shaft 41 and the second roller shaft 42. A second length adjustment component 6 for assisting in adjusting the positions of the first roller shaft 41 and the second roller shaft 42 is arranged outside the support table 3. This design enables the device to adapt to materials of different widths, ensuring that the material remains flat during the winding process and effectively preventing wrinkles or curling of the material caused by width mismatch.

[0031] The second length adjustment component 6 includes a fixed plate 61 arranged on the top of the support table 3. A connecting sleeve 62 is arranged outside the fixed plate 61. A screw 63 is threadedly connected in the connecting sleeve 62. A movable plate 64 is threadedly connected outside the screw 63. The mounting roller 4 is arranged between the movable plate 64 and the fixed plate 61. Further enhances the adaptability of the device to the width of the material, enabling the mounting roller 4 to closely adhere to the edge of the material and improving the winding efficiency and quality.

[0032] Furthermore, the first length adjustment component 5 includes an assembled threaded rod 51 arranged outside the second roller shaft 42 and a first assembly groove 52 opened in the second roller shaft 42. Allows users to quickly adjust the total length of the mounting roller 4 through simple threaded connection operations according to the width of the material, improving the flexibility and practicality of the device.

[0033] Furthermore, the first length adjustment component 5 also includes a second assembly groove 53 provided in the first roller 41, and the assembly threaded rod 51 can be threadedly connected with the second assembly groove 53. This allows the first roller 41 and the second roller 42 to be firmly connected together while maintaining the flexibility of length adjustment, thereby ensuring the stability and durability of the mounting roller 4 during the winding process.

[0034] Furthermore, the second length adjustment assembly 6 also includes a guide rod 66 disposed outside the fixed plate 61, and a through hole for the guide rod 66 to penetrate is provided in the movable plate 64. The introduction of the guide rod 66 improves the stability of the movable plate 64 during the adjustment process, prevents it from deflecting due to uneven force, and thus ensures accurate adjustment of the mounting roller 4.

[0035] Furthermore, a spacing adjustment component 7 for adjusting the position of the group of installation rollers 4 is arranged outside one group of installation rollers 4. The spacing adjustment component 7 includes a first connection frame 71 arranged at the top of the movable plate 64 and a second connection frame 72 arranged at the top of the fixed plate 61. An electric telescopic rod 73 is fixed at the top of the first connection frame 71. A slider 74 is arranged at the output end of the electric telescopic rod 73 and in the second connection frame 72. This enables the device to adapt to materials of different thicknesses, ensure that the material maintains appropriate tension during the winding process, and further prevent the occurrence of wrinkles and curling.

[0036] Furthermore, both sliders 74 are rotatably connected to the second roller shaft 42. This ensures that the mounting roller 4 rotates smoothly during the spacing adjustment process, thereby improving the winding efficiency and quality.

[0037] Example 2: Please refer to Figures 7 - 8 , combined with the first embodiment, it is further obtained that the other group of installation rollers 4 is provided with a driving anti-reversal assembly 8 for driving the group of installation rollers 4, and the driving anti-reversal assembly 8 includes a driving motor 81 provided outside the fixed plate 61, and the output shaft of the driving motor 81 is connected to the external transmission of the group of installation rollers 4, and a ratchet 83 is provided outside the side of the group of installation rollers 4 away from the output shaft of the driving motor 81, and a third connecting frame 82 is provided outside the ratchet 83, and a ratchet 84 that can mesh with the ratchet 83 is provided in the third connecting frame 82. This design effectively prevents the accidental reversal of the installation rollers 4 during the winding process, ensures the continuous and smooth transmission of the material, and further improves the winding quality.

[0038] Furthermore, the driving anti-reversal assembly 8 also includes a toggle plate 85 disposed outside the pawl 84 and a mounting frame 86 disposed in the third connecting frame 82, and a second spring 87 is fixed between the mounting frame 86 and the pawl 84. The introduction of the toggle plate 85 and the second spring 87 enables the pawl 84 to be easily separated from and re-engaged with the ratchet wheel 83, which is convenient for the user to temporarily adjust or maintain the mounting roller 4 as needed, while ensuring the stability and reliability of the pawl 84 in long-term use.

[0039] The utility model also includes a stenter setting machine, including the above-mentioned anti-curling material receiving structure.

[0040] In actual operation, in order to prevent the material from curling when the stenter setting machine body 2 is collecting the material, the following measures can be taken: First, adjust the length of the installation roller 4 according to the width of the material. First, turn the handle 65 to drive the screw 63 to rotate in the connecting sleeve 62. At the same time, under the limiting action of the guide rod 66, the movable plate 64 moves toward the fixed plate 61 to change the distance between the two. After adjusting to match the material width, stop turning the handle 65. Then, the assembly threaded rod 51 set outside the second roller shaft 42 can be rotated and installed in the second assembly groove 53 of the first roller shaft 41, and then the remaining second roller shafts 42 are installed in the first assembly groove 52 of the adjacent second roller shaft 42 through the assembly threaded rod 51 according to the spacing between the movable plate 64 and the fixed plate 61, so that the total length of the installation roller 4 reaches the width of the material.

[0041] Secondly, the distance between the two sets of installation rollers 4 can be adjusted. Open the electric telescopic rod 73, drive the slider 74 in the first connection frame 71 and the second connection frame 72 to slide, so that the overall position of the installation rollers 4 moves closer to the other set of installation rollers 4 until the distance between the two sets of installation rollers 4 meets the material thickness. After meeting the requirements, close the electric telescopic rod 73.

[0042] Next, the material is passed between the two sets of mounting rollers 4. The drive motor 81 is started, and the mounting rollers 4 connected to its output shaft rotate, and the material is transmitted with the assistance of the other set of mounting rollers 4. Since both sets of mounting rollers 4 are in contact with the outer surface of the material, the material can be effectively prevented from curling.

[0043] In addition, to ensure stable material transmission, the pawl 84 and the ratchet wheel 83 are engaged in one direction to prevent the installation roller 4 from reversing and causing the material to curl. If the material position needs to be adjusted, the dial 85 can be rotated to disengage the pawl 84 from the ratchet wheel 83. After the adjustment is completed, the dial 85 is released, and under the rebound action of the second spring 87, the pawl 84 and the ratchet wheel 83 resume engagement, keeping the ratchet wheel 83 in a one-way rotation state.

[0044] The above embodiments only express one or several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the attached claims.
