Description

Technical Field

[0001] The present application relates to the technical field of spreading machines, specifically to a multi-roller adaptive tensioning device for spreading machines. Background Art

[0002] A spreading machine is a machine specifically used to center and flatten the laundries after washing to facilitate subsequent processes such as ironing and folding the laundries. To ensure the flatness of the laundries, the spreading machine requires that each group of laundry conveyor belts be parallel and have the same linear speed. Traditionally, the tensioning of the conveyor belt is adjusted by the screws on both sides of the roller. However, in this tensioning method, if it is tightened too much, the roller will be bent. The adverse consequences are as follows: First, the middle part of the conveyor belt will be too loose, resulting in a slipping phenomenon; second, the bending of the roller will cause the entire group of belts to be non-parallel, so when conveying the laundries, the laundries will have a tendency to shrink inward, forming wrinkles and affecting the flatness of the laundries. Moreover, there may be certain errors in the length dimension of the conveyor belt itself, and after long-term operation, deformation and elongation will occur, resulting in inconsistent tension of the conveyor belt, thus affecting the inconsistent conveying speed. The laundries may shift and gather into wrinkles.

[0003] After retrieval, the publication number is CN205257631U, which discloses a spreading vehicle guide rail device on a cloth feeding machine. The inner side of the frame is equipped with a guide rail fixing frame, and a guide rail is installed on the guide rail fixing frame. The guide rail device consists of a guide rail and two slider groups. The sliders are fixed on the slider installation platform, and the sliders slide smoothly on the guide rail. A swing cylinder is installed inside the spreading vehicle, and the lower end of the swing cylinder is connected to a cloth clip device. The spreading vehicle moves quickly and smoothly on the guide rail, and the spreading vehicle spreads the laundries flatly onto the conveying equipment. When spreading the laundries, the control accuracy is accurate, improving the flatness effect of the laundries.

[0004] However, the existing spreading machines usually adopt a manual tensioning device to adjust the tension of the conveyor belt. All the roller tensions need to be adjusted at one time, which is not only complicated in operation but also requires repeated debugging to ensure the conveyance of the laundries, and it causes the spreading machine to stop for debugging, affecting the processing efficiency of the laundries.

[0005] Therefore, it is necessary to provide a multi-roller adaptive tensioning device for spreading machines to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of the present application, and therefore, it may include information that does not constitute the prior art. Utility Model Content

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present application.

[0037] See also Figures 1-4 , the utility model provides embodiments:

[0038] like Figures 1-3 As shown, the multi-roller adaptive tensioning device of the spreading machine includes a conveyor belt driving assembly 1, a conveyor belt guide plate 2, a first guide roller 5 and a second guide roller 6. A plurality of conveyor belts 4 slide on the top surface of the conveyor belt guide plate 2 driven by the conveyor belt driving assembly 1, one end of the plurality of conveyor belts 4 is sleeved on the driving roller 12 of the conveyor belt driving assembly 1, and the other end of the plurality of conveyor belts 4 is sleeved on the side wall of the second guide roller 6. The conveyor belts 4 between the driving roller 12 and the second guide roller 6 are driven in an "S" shape through the adaptive tensioning adjustment assembly 7 and the first guide roller 5, so as to adjust the tension of the plurality of conveyor belts 4 through the adaptive tensioning adjustment assembly 7.

[0039] Specifically, the mounting plate 3 is fixedly mounted on the bottom surface of one side of the conveyor belt guide plate 2, and the adaptive tensioning adjustment component 7 is hung on the side wall of the mounting plate 3. The mounting plate 3 is in a "冂" structure, and a first extension portion 33 is integrally formed inwardly on one side of the mounting plate 3, and a plurality of second hanging holes 31 with equal spacing are penetrated through the surface of the first extension portion 33. A second extension portion 34 is integrally formed outwardly on the other side of the mounting plate 3, and a plurality of groups of hanging grooves 32 with equal spacing are penetrated through the surface of the second extension portion 34.

[0040] like Figure 3 andFigure 4 As shown, the mounting plate 3 provides a hoisting support for the adaptive tensioning adjustment component 7 through the first hanging holes 74 and the hanging grooves 32 on both sides. The adaptive tensioning adjustment component 7 includes a guide component and a tensioning adjustment mechanism. The guide component includes a hook 78, a swing bracket 71 and a guide wheel 77. The hook 78 is fixedly connected to the top surface of the swing bracket 71, and the hook 78 is hung on the hanging groove 32. The side walls on both sides of the bottom of the swing bracket 71 are provided with shaft holes 76. The rotating shaft of the guide wheel 77 is rotatably connected in the shaft holes 76. A notch 72 is penetrated through the side wall of the swing bracket 71. The conveyor belt 4 wound from the driving roller 12 passes through the notch 72 and then winds around the side wall of the second guide roller 6. The conveyor belt 4 is wound from the side wall of the second guide roller 6 and then winds around the side wall of the guide wheel 77. The conveyor belt 4 is wound from the guide wheel 77 and then winds around the side wall of the second guide roller 6. The conveyor belt driving component 1 includes a driving motor 11, and the driving motor 11 is connected to the driving roller 12 through a transmission.

[0041] The multiple conveyor belts 4 are used for conveying linens in the following manner:

[0042] The plurality of conveyor belts 4 are driven by the driving motor 11 to rotate the driving roller 12, so that the plurality of conveyor belts 4 pass through the notch 72 of the swing bracket 71 respectively, and then drive the first guide roller 5 to rotate, so that each guide wheel 77 can rotate in the axial hole 76 of the swing bracket 71 driven by the conveyor belt 4, and after winding out from the guide wheel 77 and winding around the side wall of the second guide roller 6, the second guide roller 6 rotates, and the conveyor belt 4 slides from above the conveyor belt guide plate 2 and is driven by the driving roller 12 again, so that the conveyor belt 4 circulates on the driving roller 12, the first guide roller 5, the guide wheel 77 and the second guide wheel respectively, so as to provide transportation for the linens.

[0043] like Figure 4 As shown, in this process, the tensioning adjustment mechanism includes a connecting plate 73 and a spring 75. The side wall of the swing bracket 71 located above the notch 72 is integrally formed with a connecting plate 73. The side wall of the connecting plate 73 is provided with a second hanging hole 31. The two ends of the spring 75 are respectively hung in the first hanging hole 74 and the second hanging hole 31.

[0044] The principle of automatically providing tension to the conveyor belt 4 is:

[0045] The swing bracket 71 is hung at one end of a spring 75 through a connecting plate 73, and the other end of the spring 75 is hung on the first extension 33 of the mounting plate 3. Since the position of the mounting plate 3 is fixed, when the tension of the conveyor belt 4 is too loose, the elastic force of the spring 75 pulls the swing bracket 71, causing the swing bracket 71 to rotate in the hanging groove 32 through the hook 78, and causing the guide wheel 77 to rotate clockwise with the hook 78 as the center, thereby automatically tightening the conveyor belt with too loose tension. If the tension is too tight, through the stretching of the spring 75, the guide wheel 77 is driven to rotate counterclockwise with the hook 78 as the center, and the conveyor belt can be automatically loosened, so that the tension of the conveyor belt 4 can be adaptively adjusted during the process of transporting the linen by the conveyor belt 4, so as to provide a better conveying effect for the linen transportation.

[0046] Among them, the guide wheel 77 is tapered from the middle to both sides, and the diameter of the middle part of the guide wheel 77 gradually decreases towards both ends, so as to avoid the occurrence of wrinkles on the conveyor belt during the process of guiding the conveyor belt.

[0047] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
