Description

Technical Field

[0001] The utility model relates to the technical field of storage bag production, in particular to a rolling device. Background Art

[0002] Storage bags mainly include PE storage bags and non-woven storage bags. This type of environmentally friendly storage bags generally contain relatively environmentally friendly materials with low alcohol and benzene content. A winding device is required for winding during the production process.

[0003] Some devices on the market generally move the limit plate so that the distance between the two limit plates is equal to the width of the storage bag, thereby preventing the storage bag from being unevenly rolled up. At this time, the pull column moves forward, so that the air between the trapezoidal air cushion and the rotating rod is discharged into the ventilation groove. When the pull column moves backward, the air pressure inside the ventilation groove increases, so that the first stopper fits with the conical hole, and the second stopper is separated from the second air pipe. At this time, the air inside the ventilation groove is discharged through the second air pipe. After repeatedly moving the pull column back and forth, the air between the trapezoidal air cushion and the outer surface of the rotating rod is gradually reduced, thereby achieving the effect of firm adsorption between the trapezoidal air cushion and the outer surface of the rotating rod, so that the position of the limit plate is fixed.

[0004] However, in actual use of the above-mentioned device, when the storage bag is wound around the outer surface of the winding roller, the outer surface of the winding roller is relatively smooth, making it difficult to roll up the storage bag; in view of this, we propose a winding device. Utility Model Content

[0005] The purpose of the utility model is to provide a winding device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a winding device, including a mounting seat, an electric telescopic rod is arranged on one side of the mounting seat, a motor is fixedly connected to the other side of the mounting seat, a mounting piece is fixedly connected to the output end of the motor, a fixing plate is arranged on one side of the mounting piece, a card slot is arranged on one side of the fixing plate, a winding roller is fixedly connected to the other side of the fixing plate, and a limiting device is arranged on the outer surface of the winding roller, and the limiting device includes:

[0008] A rotating block, one end of the screw rod is fixedly connected to the rotating block, the outer surface of the screw rod is threadedly connected to a movable part, and the movable part is arranged in an L shape;

[0009] A pressing block is fixedly connected to one side of the movable part, the pressing block is arranged in a special-shaped block, and a semicircular rubber protrusion is arranged at the bottom of the pressing block.

[0010] Preferably, the movable part is arranged inside the installation groove, and the size of the movable part is matched with the size of the installation groove, which can make the movable part move well inside the installation groove.

[0011] Preferably, the size of the pressing block is matched with the size of the slide slot, and the position of the pressing block corresponds to the position of the slide slot, which enables the pressing block to well limit and fix the storage bag inside the slide slot.

[0012] Preferably, there are two baffles, and the two baffles are symmetrically arranged at the center of the winding roller. One end of the screw rod passes through the top of the inner wall of the mounting groove and is fixedly connected to the rotating block, which enables the rotating block to drive the screw rod to rotate well.

[0013] Preferably, a threaded sleeve is rotatably connected to the other side of the baffle, a self-locking threaded rod is internally threadedly connected to the threaded sleeve, and one end of the self-locking threaded rod is fixedly connected to a side of the fixing plate away from the slot.

[0014] Preferably, the size of the threaded sleeve is matched with the size of the self-locking threaded rod, and the threaded sleeves are evenly distributed on the other side of the baffle in a circular array.

[0015] Compared with the prior art, the utility model provides a winding device with the following beneficial effects:

[0016] 1. In order to prevent the storage bag from being unable to be well fixed on the outer surface of the winding roller when it is wound, the winding device generally puts the storage bag into the slide slot, and rotates the rotating block to rotate the screw rod, thereby moving the movable part downward, so that the movable part drives the pressing block to press the storage bag inside the slide slot, which can limit the storage bag well on the outer surface of the winding roller and keep the storage bag flat well, and the arc set on the top of the pressing block can match the outer surface of the winding roller well, and the semicircular rubber protrusion set on the bottom of the pressing block can well increase the friction between the pressing block and the storage bag, thereby making it more convenient to wind up the storage bag.

[0017] 2. In order to make the baffle plate more stably limit the wound storage bag, the threaded sleeve is rotated to make the self-locking threaded rod move inside the threaded sleeve, so that the threaded sleeve drives the baffle plate to move, so that the wound storage bag on the outer surface of the winding roller can be limited, so that the storage bag is not easily offset when it is wound.
