Description

Technical Field

[0001] The utility model relates to the technical field of hose straightening equipment, in particular to a straightening and feeding mechanism. Background Art

[0002] Hoses are a specialty tubing material made by mixing a dispersed resin and a propellant, subjecting it to shear forces in a tapered die to orient the fibers. The tubes are then dried, sintered at high temperatures, and shaped. The hoses are then heated and passed through a hose mold to produce hose-related products. Typically, the feed mechanism's forward and backward pulling speeds are mismatched with the hose mold's speed, resulting in internal stress and distortion within the hoses. This leads to instability and significant deformation, resulting in low production efficiency for hose-related products. Utility Model Content

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A straightening and feeding mechanism comprises a frame, a material tray assembly arranged at one end of the frame, a swing assembly, an X-axis straightening assembly and a Y-axis straightening assembly arranged in sequence along the conveying direction of the hose; the material tray assembly is used to place the hose, and one end of the hose passes through the X-axis straightening assembly and the Y-axis straightening assembly in sequence; the X-axis straightening assembly comprises a first fixed plate fixed to the swing assembly and a plurality of first rollers, and the plurality of first rollers are arranged in two rows on the first fixed plate along the conveying direction of the hose, and an X-axis straightening channel is formed between the two rows of first rollers; two opposite first rollers are squeezed and connected to the surface of the hose to straighten the X-axis direction of the hose, and the Y-axis straightening assembly is used to straighten the Y-axis direction of the hose; the swing assembly is fixed to the frame, and the swing assembly is used to drive the material tray assembly, the X-axis straightening assembly, and the Y-axis straightening assembly to rotate together.

[0006] By employing this technical solution, the X-axis and Y-axis straightening assemblies sequentially straighten the hose in the X and Y directions, ensuring hose output quality and improving hose production efficiency and quality.

[0025] The following is combined with Figure 1-2 , the embodiments of the utility model are further described in detail.

[0026] A straightening and feeding mechanism 1, such as Figure 1 、 Figure 2As shown, it includes a frame 2, a material tray assembly 3 mounted at one end of the frame 2, a swing assembly 4, and an X-axis straightening assembly 5 and a Y-axis straightening assembly 6 arranged sequentially along the conveying direction of the hose 8. The material tray assembly 3 is used to hold the hose 8, with one end of the hose 8 passing through the X-axis straightening assembly 5 and the Y-axis straightening assembly 6 in sequence. The X-axis straightening assembly 5 includes a first fixed plate 51 fixed to the swing assembly 4 and a plurality of first rollers 52. The plurality of first rollers 52 are arranged in two rows on the first fixed plate 51 along the conveying direction of the hose 8, forming an X-axis straightening channel between the two rows of first rollers 52. Two opposing first rollers 52 are pressed against the surface of the hose 8 to straighten the hose 8 along the X-axis. The Y-axis straightening assembly 6 is used to straighten the hose 8 along the Y-axis. The swing assembly 4 is fixed to the frame 2 and is used to drive the material tray assembly 3, the X-axis straightening assembly 5, and the Y-axis straightening assembly 6 to rotate together.

[0027] The X-axis straightening assembly 5 and the Y-axis straightening assembly 6 sequentially straighten the hose 8 in the X and Y directions, ensuring the output quality of the hose 8 and improving the production efficiency and quality of the hose. The swing assembly 4 drives the X-axis straightening assembly 5, the Y-axis straightening assembly 6, and the material tray assembly 3 to rotate at a set frequency in the direction of the generated internal stress, eliminating the internal stress generated during hose production, improving production efficiency, and ensuring the production yield of the hose.

[0028] In this embodiment, arc-shaped grooves are provided around the periphery of the first rollers 52. The hose 8 is clamped into the corresponding grooves of the two opposing first rollers 52, improving the efficiency and accuracy of straightening. Specifically, the multiple first rollers 52 are arranged in two rows, with three first rollers 52 in one row and four first rollers 52 in the other row. One of the first rollers 52 is connected to the output shaft of the corresponding X-axis motor 53. The X-axis motor 53 drives the first roller 52 to rotate, thereby driving the hose 8.

[0029] The first fixing plate 51 can be provided with multiple elongated mounting slots, with their lengths perpendicular to the conveying direction of the hose 8. The first rollers 52 are secured within the mounting slots. The mounting positions of the first rollers 52 can be adjusted to adjust the spacing between opposing first rollers 52, i.e., the width of the X-axis straightening channel, to accommodate hoses 8 of varying sizes and improve the compatibility of the equipment. The elongated mounting slots are not shown in the figure.

[0030] In this embodiment, the Y-axis straightening assembly 6 includes a second fixed plate 61 and a plurality of second rollers 62. The second fixed plate 61 is vertically mounted on the swing assembly 4. The plurality of second rollers 62 are arranged in two rows on either side of the second fixed plate 61 along the conveying direction. The two rows of second rollers 62 enclose a Y-axis straightening channel, through which the hose 8 passes. This simple structure improves straightening accuracy.

[0031] The Y-axis straightening assembly 6 further includes a Y-axis motor 63, the output shaft of which is fixedly connected to one of the second rollers 62. The X-axis straightening assembly 5 further includes an X-axis motor 53, the output shaft of which is fixedly connected to one of the first rollers 52, which can drive the hose 8 forward at a certain speed to eliminate the effects of frictional resistance.

[0032] Among them, the Y-axis straightening component 6 and the X-axis straightening component 5 have the same structure, but the installation orientation is different, which can save costs.

[0033] The straightening and feeding mechanism 1 also includes a measuring instrument 7, located at the end of the Y-axis straightening assembly 6 away from the X-axis straightening assembly 5. This instrument 7 is used to detect whether the product is properly straightened. The measuring instrument 7 monitors the deformation and deviation of the hose 8 in real time and feeds this data back to the control system. The system uses a programmable logic controller (PLC) to control the linear velocity of the hose 8 and the rotational speed of the swing assembly 4, ensuring consistency with the previous hose production machine. This eliminates internal stress generated during hose production, enabling continuous hose production and improving production efficiency. The linear velocity of the hose 8 can be controlled by adjusting the rotational speeds of the X-axis motor 53 and the Y-axis motor 63.

[0034] In this embodiment, please refer to Figure 2 The tray assembly 3 includes a connecting shaft 31, two bearing seats 32, a fixed frame 33 and a telescopic unit 34. A bearing seat 32 is provided on both sides of the fixed frame 33, and the connecting shaft 31 is sleeved in the two bearing seats 32 and the bearings are connected. The fixed frame 33 is fixedly set on the connecting shaft 31. The telescopic unit 34 is provided inside the fixed frame 33. The telescopic unit 34 is provided in at least three groups, and is provided in three groups in this embodiment. The three groups of telescopic units 34 are coaxially arranged and a storage cavity for winding the hose 8 is provided between them and the fixed frame 33 to accommodate the storage of hoses 8 of different sizes, thereby improving the compatibility of the equipment and saving costs.

[0035] A guide rail 35 is provided on each inner side of the fixed frame 33. The telescopic unit 34 comprises a curved support plate 341, two support bars 342, and two sliders 343. A support bar 342 is fixedly attached to each side of the support plate 341. A slider 343 is fixedly connected to the end of the support bar 342 away from the support plate 341. The sliders 343 slide in contact with the corresponding guide rail 35, improving adjustment efficiency and precision.

[0036] The tray assembly 3 also includes a cam 36 and a handle 37. The cam 36 is fixedly mounted on the connecting shaft 31. The handle 37 is located at the end of the connecting shaft 31 outside the fixed frame 33 and is used to manually rotate the connecting shaft 31. The telescopic unit 34 also includes a pull rod 344. One end of the pull rod 344 is fixedly connected to the inner side of the support plate 341, and the other end of the pull rod 344 is movably connected to the circumference of the cam 36. By rotating the connecting shaft 31, the cam 36 and the pull rod 344 are driven to move, thereby moving the slider 343 along the guide rail 35. The three sets of telescopic units 34 are adjusted synchronously, which increases the adjustment precision.

[0037] In this embodiment, the swing assembly 4 includes a support frame 41 and a drive motor 42. The support frame 41 is rotatably mounted on the frame 2. The output shaft of the drive motor 42 is fixedly connected to one end of the support frame 41, driving the rotation of the support frame 41. This eliminates or reduces internal stress during hose production, improving production efficiency. The tray assembly 3, X-axis straightening assembly 5, and Y-axis straightening assembly 6 are all mounted on the support frame 41.

[0038] The support frame 41 includes a support frame and support shafts disposed at both ends of the support frame. The ends of the support shafts are rotatably mounted on the support frame 41 via support seats. A drive motor 42 is mounted on the frame 2. A first gear 43 is disposed on the output shaft of the drive motor 42. A second gear 44 is fixedly connected to the corresponding end of the support shaft. The first gear 43 and the second gear 44 are meshed and connected via a chain 45, which improves rotational stability and facilitates debugging.

[0039] During adjustment, the handle 37 is manually rotated forward and reverse, causing the slider 343 to reciprocate along the guide rail 35. When the handle 37 is rotated clockwise, the connecting shaft 31 and its cam 36 rotate clockwise, causing the pull rod 344 to move toward the cam 36, driving the slider 343 and its corresponding support plate 341 along the guide rail 35 toward the connecting shaft 31. The diameter of the circle formed by the three support plates 341 decreases, and the storage chamber volume increases. When the handle 37 is rotated counterclockwise, the pull rod 344 moves toward the support plate 341, causing the slider 343 and its corresponding support plate 341 to move away from the connecting shaft 31 along the guide rail 35. The diameter of the circle formed by the three support plates 341 increases, and the storage chamber volume decreases. During the conveying of the hose 8, the measuring instrument 7 monitors the deformation and deviation of the hose 8 in real time and feeds this data back to the control system. The system uses the PLC to control the linear velocity of the hose 8 and the rotational speed of the swing assembly 4 to ensure consistency with the main hose production unit. The device can achieve different travel speeds by adjusting the position, angle and pressure of the first roller 52 and the second roller 62.

[0040] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
