In the figure: the device comprises a frame 10, a power roller 11, a support plate 12, a limiting groove 13, a guide plate 14, a chain 15, a lug 16, a connecting bolt 17, a winding shaft 20, an extension shaft 21 and a chain wheel 22.

Detailed Description

The following describes embodiments of the present invention with reference to the accompanying drawings.

Referring to fig. 1 and 2, a sprocket-supported self-winding device for medical plastic films comprises support plates 12 mounted on two sides of a frame 10, a sprocket support device is mounted on the side surface of each support plate 12, and two ends of a winding shaft 20 are respectively provided with a rotating sprocket 22; the end of the support plate 12 connected with the frame 10 is lower than the end far away from the frame 10, and the sprocket support devices on the support plates 12 on both sides respectively lift the winding shaft 20 in cooperation with the sprockets 22 on both sides of the winding shaft 20. Through set up sprocket strutting arrangement in the side of backup pad 12, sprocket 22 cooperatees with sprocket strutting arrangement, can effectual restriction rolling axle 20 produce axial displacement at the in-process of operation rolling to film is the situation of leaking hopper-shaped after having avoided the rolling, has improved product quality. In actual production, the rack 10 is provided with a power roller 11, and the rotation of the power roller 11 drives the rotation of the winding shaft 20, so as to drive winding. Because the one end that backup pad 12 and frame 10 are connected is less than the one end of keeping away from frame 10, makes rolling axle 20 support all the time and leans on power cylinder 11, along with the increase of rolling, the diameter grow of film 30 on the rolling axle, and the rolling axle is along with sprocket strutting arrangement slow movement backward, at the in-process that removes, thereby the axial displacement of spacing rolling axle 20 through the removal route of restriction sprocket 22, for example can adopt with it cooperation chain or be used for the card to establish the draw-in groove of sprocket, all can be used to in the sprocket strutting arrangement.

Referring to fig. 2, in a preferred embodiment, the sprocket supporting device includes a guide plate 14 installed at a side of the support plate 12, an upper side of the guide plate 14 having an inclination angle corresponding to an upper side of the support plate 12, and a chain 15 installed on the guide plate 14; the chain 15 is matched with the chain wheel 22, the structure is simple, the manufacturing is convenient, the processing cost is low, and the chain 15 is used for limiting the chain wheel 22. Furthermore, a rotating wheel is arranged at a position, corresponding to the support plate 12, on one side of the chain wheel 22, the rotating wheel is matched with the support plate 12 and used for bearing a winding shaft, and meanwhile, the chain 15 is used for limiting the chain wheel 22 and is suitable for large and heavy working conditions. The guide plates 14 may be mounted on the opposite inner sides of the support plate 12, or may be mounted on the outer sides of the support plate 12; or one inside and one outside, all fulfill the support function.

Referring to fig. 1 and 2, in a further preferred embodiment, an upward flange is arranged on the upper side surface of the guide plate 14 along the installation direction of the chain 15, the chain 15 is clamped on the flange, downwardly extending protrusions 16 are arranged on the lower side surface of the guide plate 14 near two ends, connecting bolts 17 are arranged at two ends of the chain 15, and the connecting bolts 17 are fixed by nuts after penetrating through holes in the protrusions 16. The chain 12 is prevented from falling by the flange restraining the chain 15. The flange can be a convex part which is matched with the chain and is positioned in the middle of the chain; or may be raised portions on both sides of the chain to form pockets to retain the chain 15. Connecting bolts 17 are arranged at two ends of the chain 15, can be detachably mounted, are convenient to mount and replace, and are also convenient to tighten the chain 15 when the chain 15 is not flexible.

Referring to fig. 1 and 2, in a preferred embodiment, the supporting plate 12 is provided with a limiting groove 13 at an end far away from the frame 10. The winding shaft 20 together with the wound plastic film is prevented from falling after the winding reaches a certain diameter.

Further, the winding shaft 20 is an inflatable shaft, the two ends of the inflatable shaft are provided with extension shafts 21, and the chain wheel 22 is mounted on the extension shafts 21, so that the wound plastic die can be taken down conveniently.

The utility model discloses a working process and principle:

the frame 10 is equipped with power cylinder 11, because the one end that backup pad 12 and frame 10 are connected is less than the one end of keeping away from frame 10, and the corresponding inclination that has of the side of going up of backup pad 12 on the upper flank of deflector 14, makes rolling axle 20 can support against power cylinder 11 under the natural state, thereby power cylinder 11 rotates the rotation that drives rolling axle 20 to carry out the rolling. Treat that rolling film 30 twines on the rolling pipe, the rolling pipe suit is on the physiosis axle, the fixed rolling pipe of rolling after the physiosis axle adds compressed air, the one end that backup pad 12 and frame 10 are connected is less than the one end of keeping away from frame 10, make the rolling pipe support all the time and lean on power drum 11, along with the increase of rolling, the diameter grow of film 30 on rolling shaft 20, the rolling shaft is along with sprocket strutting arrangement rear slow movement, at the in-process that removes, through the removal route of restriction sprocket 22, thereby the axial displacement of spacing rolling shaft 20.
