Description

Technical Field

[0001] The utility model relates to a swing rod device. Background Art

[0002] In disposable sanitary products equipment such as sanitary napkins, diapers, and mattresses, a rocker device is used to maintain constant tension to ensure stable operation of the equipment.

[0003] At present, the common swing rod device uses the form of cylinder extension to maintain the tension stability, but the cylinder method cannot well ensure the stability of the tension in some cases. In further improvements, as shown in the patent document with document number CN207957288U and name, a tension swing rod device, a servo motor is used to maintain the tension stability of the swing rod device. However, it is found in practice that the above device still has the following problems:

[0004] First, the existing swing arm device usually adopts a cantilever structure. When maintaining the tension of large-format materials, such as 600mm or larger width, the far end of the transition wheel wears relatively severely, so that after long-term use, the material is prone to position deviation or requires the downstream corrector to adopt a larger correction angle or displacement;

[0005] Second, the single-sided drive form is adopted on the inner side of the frame. Since the driving components have a larger structural weight and the transition wheel is lighter, the force on one side is not balanced, which can easily lead to excessive wear of the bearing on the installation side and reduce the service life.

[0006] Therefore, it is necessary to provide a new solution to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] The embodiment of the utility model provides a swing rod device, and the application will be further described below with reference to the accompanying drawings.

[0028] At the same time, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] Please refer to the attached Figures 1 to 5 The swing arm device includes a support frame and a tension adjustment component arranged on the support frame.

[0030] The support frame is arranged on the frame 10 and is used to provide support for the tension adjustment component. The support frame includes at least three main supports. One end of the main support is fixed on the frame 10, and the other end extends away from the frame 10. In this embodiment, there are three main supports, including a first main support 21, a second main support 22, and a third main support 23 arranged between the first main support 21 and the second main support 22.

[0031] The first main support 21 includes a connecting plate 211 and a main cross bar 212 arranged on the connecting plate 211, wherein the connecting plate 211 is fixed to the frame 10 by bolts, one end of the main cross bar 212 is fixed to the connecting plate 211, and the other end extends in a direction away from the connecting plate 211 in a form perpendicular to the connecting plate 211 to form a cantilever structure.

[0032] In this embodiment, the connecting plate 211 includes a plurality of waist-shaped holes, and the length direction of the waist-shaped holes is parallel to the vertical direction, that is, the connecting plate 211 can be adjusted in the vertical direction. At the same time, the first main support 21 also includes an upper limit member 213 arranged on the upper side of the connecting plate 211 and a lower limit member 214 arranged on the lower side of the connecting plate 211. The upper position of the connecting plate 211 in the vertical direction is limited by the upper limit member 213, and the lower position of the connecting plate 211 in the vertical direction is limited by the lower limit member 214. Specifically, the upper limit member 213 includes an upper limit plate 2131 fixed to the frame 10 and an upper limit bolt 2132 arranged on the upper limit plate 2131. The upper limit plate 2131 includes an upper screw hole along the vertical direction. The upper limit bolt 2132 is penetrated in the upper screw hole, and the upper limit bolt 21 One end of the lower limit bolt 2142 abuts against the connecting plate 211 to limit the upper position of the connecting plate 211, and the lower limit member 214 includes a lower limit plate 2141 fixed on the frame 10 and a lower limit bolt 2142 arranged on the lower limit plate 2141, and the lower limit plate 2141 includes a lower screw hole along the vertical direction, and the lower limit bolt 2142 is passed through the lower screw hole, and one end of the lower limit bolt 2142 abuts against the connecting plate 211 to limit the lower position of the connecting plate 211. It can be understood that the upper limit member 213 and the lower limit member 214 can easily adjust the position of the connecting plate 211 in the vertical direction, and the upper limit member 213 and the lower limit member 214 can clamp the connecting plate 211 and fix the bolts to firmly limit the position of the connecting plate 211 and the first main support 21, thereby preventing the first main support 21 from unexpected displacement.

[0033] Furthermore, there are at least two upper limit bolts 2132 and lower limit bolts 2142, and the upper limit bolts 2132 and the lower limit bolts 2142 are correspondingly arranged to prevent the connecting plate 211 from rotating and maintaining a horizontal direction.

[0034] It can be understood that a pair of distance rods are arranged between adjacent main supports. Specifically, a first distance rod 241 and a second distance rod 242 are included between the first main support 21 and the third main support 23, and a third distance rod 243 and a fourth distance rod 244 are included between the second main support 22 and the third main support 23. At the same time, the first distance rod 241 and the third distance rod 243 are collinear, and the second distance rod 242 and the fourth distance rod 244 are collinear. The collinearity means that the center lines of the correspondingly arranged distance rods are on the same straight line.

[0035] Furthermore, the cross-sections of the first distance rod 241, the second distance rod 242, the third distance rod 243 and the fourth distance rod 244 are all rectangular tubular cross-sections.

[0036] Furthermore, the first distance rod 241 includes an end plate 2411, which is attached to the side of the main cross bar 212 and connected to the end plate 2411 and the main cross bar 212 by bolts, and the bolts connect the end plate 2411 and the main cross bar 212 in a horizontally installed form. Similarly, the first distance rod 241 is connected to the third main support 23 in the above manner. It can be understood that each main support is connected into a whole through the first distance rod 241, the second distance rod 242, the third distance rod 243 and the fourth distance rod 244. At the same time, since the first distance rod 241 and the second distance rod 242 are of equal length, the first main support 21 and the third main support 23 have the same longitudinal position and spacing. Similarly, the second main support 22 and the third main support 23 have the same longitudinal position and spacing.

[0037] Furthermore, the first distance rod 241, the second distance rod 242, the third distance rod 243 and the fourth distance rod 244 are of equal length.

[0038] Furthermore, the first main support 21 also includes a first support plate 2121, and the first support plate 2121 includes a transverse plate and a longitudinal plate perpendicular to the transverse plate, so that the entire first support plate 2121 is T-shaped, and the transverse plate is used to fix the drive assembly, and the transverse plate is fixed to the main cross bar 212 by welding, and the end plate 2411 is fixed to the longitudinal plate. Through the above method, the position of the drive assembly can be maintained more stably, and at the same time, the structure of the entire support frame has a higher stability to prevent unexpected position changes due to influences such as vibration.

[0039] Please refer to Figure 5 The second main support 22 is provided with a second support plate 221 , and the second support plate 221 is used to fix the driven wheel 313 .

[0040] Furthermore, the second support plate 221 is fixed to the second main support 22 by a plurality of bolts, and the second support plate 221 includes a plurality of waist-shaped holes along the horizontal direction. It can be understood that the position of the second support plate 221 can be adjusted along the length direction of the waist-shaped holes.

[0041] Furthermore, an adjusting bolt 222 is also included between the second main support 22 and the second support plate 221, one end of the adjusting bolt 222 is threadedly connected to the second support plate 221, and the other end extends out of the second main support 22. At the same time, the length direction of the adjusting bolt 222 is parallel to the length direction of the waist-shaped hole. On the one hand, a pulling force can be applied to the second support plate 221 by the adjusting bolt 222 to prevent the second support plate 221 from moving along the force direction of the driven wheel 313. At the same time, the adjusting bolt 222 can conveniently adjust the position of the second support plate 221 in its extension direction. In the figure, the extension direction is the left and right direction.

[0042] The tension adjustment assembly includes a driving assembly, a pair of guide rods 25, and a first movable seat 41 and a second movable seat 42 that are movably arranged on the pair of guide rods 25 and driven by the driving assembly and move synchronously in opposite directions. The first movable seat 41 and the second movable seat 42 are each provided with a plurality of guide rollers in sequence from top to bottom, and the driving assembly is equidistantly arranged between the pair of guide rods 25.

[0043] In this embodiment, the guide rod 25 is arranged directly above the distance rod. Specifically, the guide rod 25 includes a first guide rod and a second guide rod, wherein the first guide rod is arranged directly above the first distance rod 241 and the third distance rod 243, and the second guide rod is arranged directly above the second distance rod 242 and the fourth distance rod 244.

[0044] The first movable seat 41 and the second movable seat 42 are movably arranged on the first guide rod and the second guide rod, and are respectively located on both sides of the first guide rod and the second guide rod. It can be understood that the first movable seat 41 is straddled on the first guide rod and the second guide rod, and the second movable seat 42 is straddled on the first guide rod and the second guide rod.

[0045] Furthermore, a linear bearing 416 is provided between the first movable seat 41 and the first guide rod and the second guide rod, and a linear bearing 416 is provided between the second movable seat 42 and the first guide rod and the second guide rod.

[0046] The driving assembly includes a driving device 311, a driving wheel 312 connected to the driving device 311, a driven wheel 313 arranged on the second support plate 221, and a driving belt 32 arranged between the driving wheel 312 and the driven wheel 313, wherein the driving belt 32 includes a first section 321 adjacent to one side of the frame 10 and a second section 322 facing away from the first section 321. It can be understood that when the driving wheel 312 rotates under the drive of the driving device 311, the movement directions of the first section 321 and the second section 322 are opposite, the first movable seat 41 is fixedly connected to the first section 321, and the second movable seat 42 is fixedly connected to the second section 322, so that when the driving device 311 drives the driving wheel 312 to rotate, the movement directions of the first movable seat 41 and the second movable seat 42 are opposite.

[0047] Furthermore, the driving belt 32 is a synchronous belt.

[0048] It can be understood that the driving assembly is arranged between the first guide rod and the second guide rod, and is equidistant from the first guide rod and the second guide rod. The equidistant means that the distance between the rotation center of the driving wheel 312 and the first guide rod is equal to the distance between the rotation center of the driving wheel 312 and the second guide rod. More specifically, the distance between the first section 321 and the first guide rod is equal to the distance between the second section 322 and the second guide rod.

[0049] It can be understood that by adjusting the position of the second support plate 221 through the adjusting bolt 222 , the driving belt 32 can be kept or maintained at a fixed position, thereby preventing the position change caused by the loosening of the driving belt 32 .

[0050] The first movable seat 41 includes a left support plate 411, a right support plate 412 and a middle connecting rod 413 connecting the left support plate 411 and the right support plate 412, so that the first movable seat 41 is H-shaped, and a plurality of first guide rollers 414 are arranged between the left support plate 411 and the right support plate 412. It can be understood that the plurality of first guide rollers 414 are arranged in sequence from top to bottom, and the two ends of the first guide rollers 414 are rotatably arranged on the left support plate 411 and the right support plate 412 respectively.

[0051] Furthermore, the rotation axes of the first guide rollers 414 are located on the same vertical plane.

[0052] Furthermore, the first movable seat 41 includes a first clamping plate 415 , and the first clamping plate 415 is clamped on the first section 321 .

[0053] The second movable seat 42 has a substantially identical structure to the first movable seat 41 , and includes a plurality of second guide rollers 424 , the rotation axes of the second guide rollers 424 also being located on the same vertical plane. Meanwhile, the second movable seat 42 includes a second clamping plate 425 , which is clamped on the second section 322 .

[0054] It is understandable that through the above settings:

[0055] On the one hand, support structures are formed at both ends of the first guide roller 414 and the second guide roller 424, so that the first guide roller 414 and the second guide roller 424 are no longer cantilever structures, which can provide more effective support for materials with a large width and reduce the problem of material position deviation caused by far-end wear of the first guide roller 414 and the second guide roller 424.

[0056] Secondly, the adopted support frame forms a "sun"-shaped structure, which has a stable structure. At the same time, due to the setting of the distance rod, the position and shape of the frame can be accurately fine-tuned during the installation and debugging process to ensure the vertical and horizontal positions of the first guide roller 414 and the second guide roller 424.

[0057] Thirdly, the drive assembly is arranged between the first guide rod and the second guide rod, and is arranged equidistantly, so that the force is balanced during the drive adjustment process and the service life is extended. It is found in practice that the above structure reduces the material offset problem by 12% and extends the bearing life by 6% compared with the existing technology.

[0058] The above description is only an implementation method of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present utility model.
