A kind of unwinding device for producing soft wet wipes

Abstract

The utility model discloses an unwinding device for producing soft wet wipes, including a base. The utility model provides a tensioning component. When the unwinding device works normally, the wet wipe roll provides downward pressure on the auxiliary roller to keep the spring in a compressed state. When the wet wipe roll is loose, the force received by the spring is reduced, and the spring stretches upward, driving the movable plate and the sliding rod to move upward, and adjusting the tension of the wet wipe roll through the auxiliary roller. When the upward movement height is too high, the movable plate pulls up the iron block through the elastic rope, and the control switch is turned on to control the rotation of the bidirectional motor. The bidirectional motor drives the screw to rotate, and the screw and the moving plate are threadedly moved to control the movement of the moving plate, so as to adjust the unwinding distance and perform secondary adjustment on the tension of the wet wipe roll. At the same time, the bidirectional motor is externally connected to a controller to control the reverse rotation of the bidirectional motor and drive the moving plate to reset, which is convenient for subsequent use.

Description

Technical Field

[0001] The utility model relates to the technical field of unwinding devices, in particular to an unwinding device for producing soft wet wipes. Background Art

[0002] The production of soft wet wipes usually involves an unwinding device, which is used to unwind materials such as roll paper or non-woven fabrics and supply them to subsequent processing links. The unwinding device is an important part of the entire production line. Its design and function determine the production efficiency and product quality. A common unwinding device for the production of soft wet wipes uses tension control to adjust the supply speed of the roll paper. It includes a roll paper holder, the roll paper is driven and tensioned by a tension control device, and then unrolled through a guide device and fed into subsequent processing equipment. In addition, the unwinding device for the production of soft wet wipes may also be equipped with an automatic paper breaking system, which is used to replace the roll paper with a new one in time after the roll paper is used up to ensure the continuity of production.

[0003] The prior art provides an unwinding device for wet wipes production that is easy to disassemble and assemble (Announcement No.: CN216105015U), which includes an unwinding device body, and is also provided with a No. 1 roller mounting frame, a drive motor, a motor placement plate, a No. 2 roller mounting frame, an auxiliary unwinding roller, a fixing mechanism, a detachable roller and a wet wipes roll, wherein the fixing mechanism includes an unwinding device base, a fixing block, a right-angle limit block and a slotted mounting plate. The utility model describes an unwinding device for wet wipes production that is easy to disassemble and assemble. The slotted mounting roller block is used to facilitate the installation of the unwinding device body on the ground or platform, and the fixed block and the right-angle limit block are used to facilitate the installation of the unwinding device body and the motor placement plate on the unwinding device base. The detachable roller is used to facilitate the replacement of the wet wipes roll after the wet wipes roll is unwound, which brings better prospects for use in the field of wet wipes production device technology.

[0004] But the device still has the following defects:

[0005] When the device is in use, the wet wipes are not tensioned. The soft wet wipes are too loose during the unwinding process, which may lead to the following results: the wet wipes that are too loose may cause uneven tension during the unwinding process, that is, one part of the wet wipes is too loose and the other part is too tight. This will cause problems in the subsequent process steps of the wet wipes, such as uneven cutting or folding, increased defective product rate, and reduced production efficiency. The operator may need to frequently stop the machine, adjust the device or re-unwind to ensure that the tension and quality of the wet wipes meet the requirements. Therefore, we need to propose an unwinding device for the production of soft wet wipes. Utility Model Content

[0029] The tensioning assembly 10 includes two fixed tubes 101 fixedly installed on the upper end of the base 1, and control switches 102 are provided inside the two fixed tubes 101 and at the upper end of the base 1. The upper end of the control switch 102 abuts against an iron block 103, and the upper end of the iron block 103 is fixedly connected to an elastic rope 104, and a spring 105 is sleeved on the outer side of the elastic rope 104. A movable disk 106 is slidably connected to the inside of the fixed tube 101, and a sliding rod 107 is fixedly connected to the upper end of the movable disk 106, and the sliding rod 107 is slidably connected to the inside of the fixed tube 101.

[0030] Both control switches 102 are normally closed switches, and the two control switches 102 are connected in series through a line.

[0031] Exemplarily, when the two control switches 102 are turned on at the same time, the line will be energized.

[0032] The spring 105 is disposed inside the fixed tube 101 , and when the unwinding device works normally, the spring 105 is in a compressed state.

[0033] Exemplarily, when the unwinding device works normally, the wet wipes roll 8 provides downward pressure to the auxiliary roller 12, so that the spring 105 remains in a compressed state.

[0034] The moving component includes a slide groove 2 opened inside the base 1, and a screw rod 3 is rotatably connected inside the slide groove 2. One end of the screw rod 3 passes through the base 1 and a bidirectional motor 4 is fixedly installed thereon. The outer side of the screw rod 3 is threadedly connected to a moving plate 5, and the moving plate 5 is slidably connected to the inside of the slide groove 2.

[0035] Exemplarily, the bidirectional motor 4 drives the screw 3 to rotate, and the screw 3 and the moving plate 5 move in a threaded manner, thereby controlling the movement of the moving plate 5 to adjust the unwinding distance.

[0036] The bidirectional motor 4 is electrically connected to the control switch 102 .

[0037] Exemplarily, the two control switches 102 control the start and stop of the bidirectional motor 4 .

[0038] The unwinding assembly includes two support plates 6 fixedly mounted on the upper end of the movable disk 106, an unwinding roller 7 is arranged inside the two support plates 6, a wet wipes roll 8 is arranged outside the unwinding roller 7, and one end of the unwinding roller 7 passes through the support plate 6 and is fixedly connected to an unwinding motor 9.

[0039] Exemplarily, the unwinding motor 9 drives the unwinding roller 7 to rotate, and unwinds the wet wipes roll 8 on the unwinding roller 7 , and the support plate 6 supports the unwinding motor 9 and the unwinding roller 7 .

[0042] Working principle: When the utility model is used, the unwinding motor 9 drives the unwinding roller 7 to rotate, and unwinds the wet wipes roll 8 on the unwinding roller 7. After the wet wipes roll 8 passes through the auxiliary roller 12, it is put into the later processing. When the unwinding device works normally, the wet wipes roll 8 provides downward pressure to the auxiliary roller 12, so that the spring 105 remains in a compressed state. When the wet wipes roll 8 is loose, the force received by the spring 105 is reduced, and the spring 105 stretches upward, driving the moving disk 106 and the sliding rod 107 to move upward. The tension of the wet wipes roll 8 is adjusted by the auxiliary roller 12. When the upward movement height is too high, the moving disk 106 and the sliding rod 107 are moved upward. The disk 106 pulls up the iron block 103 through the elastic rope 104, and the control switch 102 is turned on to control the rotation of the bidirectional motor 4. The bidirectional motor 4 drives the screw 3 to rotate, and the screw 3 and the movable plate 5 move threadedly to control the movement of the movable plate 5, adjust the unwinding distance, and perform a secondary adjustment on the tension of the wet wipes roll 8. The wet wipes roll 8 presses down the auxiliary roller 12 again, and the movable disk 106, the iron block 103 and other components are controlled to descend, and the control switch 102 is closed. At the same time, the bidirectional motor 4 is externally connected to a controller to control the bidirectional motor 4 to rotate in the opposite direction, and drive the movable plate 5 to reset, so as to facilitate subsequent use.
