Abstract

A flexible roll material multi-specification unwinding device includes an automatic coupling mechanism installed in the middle of the frame, belt drives installed on both sides below the automatic coupling mechanism, and a roll material gripping mechanism. The roll material gripping mechanism mainly consists of a guide rail and two longitudinal rods. The guide rail is installed on the bottom surface of a crossbeam, and the two longitudinal rods are respectively connected to the two ends of the guide rail via slides. A cylinder A is installed on the crossbeam inside the longitudinal rod, and the outer end of the piston rod A of the cylinder A is connected to the longitudinal rod through a connecting seat. A sleeve column is provided on the inner side of the lower end of the longitudinal rod, and a rotating shaft is coaxially provided on the sleeve column. The rotating shaft is connected to a bearing with a seat on the longitudinal rod. This device separates the rotational support and linear movement of the sleeve column. There is only a rotational support structure between the sleeve column and the longitudinal column, which does not undertake the task of moving and docking. By increasing the support strength of the positioning column head, the loosening and misalignment of the positioning column head during use are avoided, thereby improving the service life of the unwinding device.

Description

Technical Field

[0001] This utility model relates to the field of wet wipe processing equipment, and in particular to a flexible roll material multi-specification unwinding device. Background Technology

[0002] In the production of wet wipes, rolls of non-woven fabric substrate need to be placed into an unwinding device, which then unwinds and transports the fabric to subsequent processing steps.

[0003] The utility model patent with application number CN202320529345.0 discloses an automatic feeding device for non-woven fabric. The device lifts the non-woven fabric roll by inserting the positioning pin of the automatic gripping mechanism into both ends of the roll's central cylinder, and then unwinds it under the action of a belt conveyor.

[0004] The drive assembly of the automatic gripping mechanism includes a support plate horizontally fixed to the lower end face of the vertical support rod, a slide rail fixedly connected to one side of the support plate along its length, and a cylinder fixed to the other side of the support plate. The positioning pin is slidably connected to the slide rail via a slider, and the outer end of the piston rod of the cylinder is fixed to an extension plate on one side of the slider. The problem is that the positioning pin itself is connected to a slider on the slide rail via a rotating bracket, integrating the rotational support and linear sliding gripping of the positioning pin. This weakens the support strength of the positioning pin, making it prone to loosening and misalignment during use, which needs improvement. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a flexible roll material multi-specification unwinding device.

[0006] The technical solution of this utility model is: a flexible roll material multi-specification unwinding device, including an automatic coupling mechanism installed in the middle of the frame, belt drives and roll material gripping mechanisms installed on both sides below the automatic coupling mechanism. The roll material gripping mechanism mainly consists of a guide rail and two longitudinal rods. The guide rail is installed on the bottom surface of a crossbeam and connected to the frame through the crossbeam. Crossbeams are provided on both sides of the automatic coupling mechanism. The length direction of the crossbeam is consistent with the width direction of the frame. The two longitudinal rods are respectively connected to the two ends of the guide rail through a slide. The longitudinal rods and the slide are vertically fixedly connected as one unit. A cylinder A is installed on the crossbeam inside the longitudinal rod. The outer end of the piston rod A of the cylinder A is connected to the longitudinal rod through a connecting seat. The length direction of the telescopic rod of the cylinder A is consistent with the length direction of the guide rail. A sleeve column is provided on the inner side of the lower end of the longitudinal rod. The sleeve columns on both sides are arranged coaxially. A rotating shaft is coaxially provided on the sleeve column. The rotating shaft is connected to a bearing with a seat on the longitudinal rod.

[0007] Preferably, the belt drive is rotatably connected to the middle of the crossbeam, and a cylinder B is rotatably connected to the middle of the crossbeam via a hinged support. The inner end of the cylinder B is rotatably connected to the hinged support, and the piston rod B of the cylinder B is hinged to the upper part of the outer side of the belt drive. The outer end of the piston rod B is provided with a radial connection hole.

[0008] Preferably, triangular reinforcing plates are provided on both sides of the longitudinal bar and between the crossbeam, and the triangular reinforcing plates are right-angled triangular plates.

[0009] Preferably, the inner end of the sleeve column is coaxially provided with a tapered body, the tapered body is coaxially arranged with the sleeve column, and the outer end is provided with a limiting protrusion.

[0010] Preferably, the guide rails are arranged side by side, with the length direction of the guide rails consistent with the length direction of the crossbeam, and the longitudinal rod is connected to the slide on the two guide rails through a flat plate seat.

[0011] Preferably, a plurality of guide rollers are evenly arranged side by side at the upper end of the frame, and support plates are provided at both ends of the guide rollers. The support plates are vertically fixed to the frame, and the guide rollers are arranged along the width direction of the frame.

[0012] The beneficial technical effects of this utility model are as follows: This utility model drives the longitudinal rod to slide through the cylinder A, thereby realizing the linear drive of the sleeve column at the lower end of the longitudinal rod. This method separates the rotational support and linear movement of the sleeve column. There is only a rotational support structure between the sleeve column and the longitudinal column, which does not undertake the task of moving and docking. By increasing the support strength of the positioning column head, it avoids the phenomenon of loosening or misalignment of the positioning column head during use, ensuring the integrity of production and improving the service life of the unwinding device.

[0019] Example 1, see appendix Figure 1-5 A flexible roll material multi-specification unwinding device includes an automatic coupling mechanism 2 installed in the middle of a frame 1, belt drives 3 installed on both sides below the automatic coupling mechanism 2, and a roll material gripping mechanism. The roll material gripping mechanism mainly consists of a guide rail 41 and two longitudinal rods 43. The guide rail 41 is installed on the bottom surface of a crossbeam 11 and connected to the frame 1 through the crossbeam 11. The two longitudinal rods 43 are respectively connected to the two ends of the guide rail 41 through sliders 42. The two longitudinal rods 43 slide in opposite directions to adjust the gripping distance. The crossbeam inside the longitudinal rods 43... A cylinder A 45 is installed on the 11. The outer end of the piston rod A 451 of the cylinder A 45 is connected to the longitudinal rod 43 through the connecting seat 47. The cylinder A 45 pushes and pulls the end of the longitudinal rod 43 through the piston rod, so that the longitudinal rod 43 slides along the guide rail 41 through the slide block 42. A sleeve column 44 is provided on the inner side of the lower end of the longitudinal rod 43. A rotating shaft 443 is coaxially provided on the sleeve column 44. The rotating shaft 443 is connected in the seated bearing 444 provided on the longitudinal rod 43, and the seated bearing 444 provides rotational support for the sleeve column 44.

[0020] Triangular reinforcing plates 48 are provided on both sides of the longitudinal bar 43 and between the crossbeam 11 to improve the fixed connection strength between the longitudinal bar 43 and the crossbeam 11, thereby improving the support strength of the roll material.

[0021] The inner end of the sleeve column 44 is coaxially provided with a tapered body 441, and the outer end is provided with a limiting flange 442. The tapered body 441 makes it easy to guide the sleeve column 44 into the center cylinder of the roll material, and the limiting flange 442 plays the role of axial limiting, avoiding axial displacement of the roll material and ensuring unwinding stability.

[0022] The guide rails 41 are arranged side by side, and the longitudinal rod 43 is connected to the slider 42 on the two guide rails 41 through the flat plate seat 46. The double guide rail 41 structure has stronger sliding support stability.

[0023] Several guide rollers are evenly arranged side by side at the upper end of the frame 1. The guide rollers are arranged along the width direction of the frame 1. The substrate is unwound and enters the automatic connecting mechanism 2, and then exits from the automatic connecting mechanism 2 and enters the guide rollers. The guide rollers provide conveying guidance for the substrate.

[0024] In this embodiment, the flexible roll material multi-specification unwinding device drives the longitudinal rod 43 to slide along the guide rail 41 via cylinder A 45. The lower end of the longitudinal rod 43 is fitted with a column 44, which moves with the longitudinal rod 43. This separates the rotational support and linear movement of the fitted column 44. Only the rotational support structure is retained between the fitted column 44 and the longitudinal column, and it does not undertake the task of moving and docking. By increasing the support strength of the positioning column head, the loosening or misalignment of the positioning column head during use is avoided, ensuring the integrity of production and improving the service life of the unwinding device.

[0025] Example 2, see appendix Figure 1 , 5 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the belt drive 3 is rotatably connected to the middle of the crossbeam 11. The middle of the crossbeam 11 is rotatably connected to the cylinder B 32 through the hinge support 31. The cylinder B 32 is arranged at an angle upward. The piston rod B of the cylinder B 32 is hinged to the upper part of the outer side of the belt drive. The piston rod B of the cylinder B 32 pushes and pulls the belt drive 3, driving the belt drive 3 to rotate, so that the belt on the belt drive 3 is pressed or removed from the outer side of the roll material.

[0026] In this embodiment, the belt drive 3 is placed between the longitudinal rods 43 on both sides, and the cylinder 32 is connected to the crossbeam 11. Thus, the belt drive 3 and the roll gripping mechanism are both integrated onto the crossbeam 11. Compared with the existing assembly method of mounting the belt drive 3 between the legs of the frame 1, the structure is more compact and meets the design requirements of miniaturization and lightweighting.
