The utility model provides an unreeling mechanism for a preservative film rewinder, which can adapt to different large-roll sizes.
The technical scheme adopted by the utility model for solving the technical problems is that the unreeling mechanism for the preservative film rewinder comprises a large-roll clamping part and a large-roll unreeling part, wherein the large-roll clamping part is oppositely arranged on an angle adjusting mechanism, and a spacing adjusting mechanism is arranged between the large-roll clamping parts.
As a preferable mode of the above-mentioned scheme, the angle adjusting mechanism includes two turntables and at least two slide bars provided between the two turntables, and the large-roll holding portion is slidably provided on the slide bars.
As a preferable scheme of the scheme, the large coil clamping part comprises a sliding block arranged on the sliding rod in a sliding way, a vertical plate is arranged on the sliding block, and a first clamping head propped against the end part of the large coil is rotatably arranged at the upper end of the vertical plate.
As a preferable mode of the above-mentioned scheme, the first clamping head is in a truncated cone shape.
As a preferable scheme of the scheme, the large-roll unreeling part comprises two first roller bodies which are positioned on the same vertical surface, and a belt for driving the large roll to rotate is arranged between the two first roller bodies.
As a preferable scheme of the scheme, the interval adjusting mechanism is positioned in a gap between the sliding rails, and two ends of the interval adjusting mechanism are respectively fixed with the two large-roll clamping parts.
As a preferable mode of the above-mentioned mode, the pitch adjustment mechanism is a cylinder.
The utility model has the advantages that: the first clamping head in the shape of a circular table is adopted, so that large-roll reels with different diameters can be adapted; the gap adjusting mechanism is arranged to adapt to large rolls with different lengths; the angle adjusting mechanism is arranged, so that the large coil can be always propped against the large coil unreeling part in the unreeling process, and the unreeling efficiency is ensured.

Detailed Description
The technical scheme of the utility model is further described below through examples and with reference to the accompanying drawings.
Examples:
The embodiment relates to an unreeling mechanism for a preservative film rewinder, which comprises a large-roll clamping part and a large-roll unreeling part, wherein the large-roll clamping part is oppositely arranged on an angle adjusting mechanism, and a spacing adjusting mechanism is arranged between the large-roll clamping parts, as shown in fig. 1.
The large-volume unreeling part comprises two first roller bodies 7 which are positioned on the same vertical surface, a certain gap is reserved between the two first roller bodies 7, and meanwhile, a belt 8 is arranged between the two first roller bodies. During operation, the two first roller bodies drive the leather.
The angle adjusting mechanism comprises two turntables 1 and at least two sliding rods 2 arranged between the two turntables, the large-roll clamping part comprises a sliding block 3 arranged on the sliding rods 2 in a sliding manner, a vertical plate 4 is arranged on the sliding block 3, a first clamping head 5 propped against the end part of the large roll is rotatably arranged at the upper end of the vertical plate 4, and the first clamping head is in a round table shape.
In this embodiment, the middle distance adjusting mechanism is an air cylinder 6, the air cylinder 6 is located in a gap between the slide bars 2, and two ends of the air cylinder are respectively fixed with the slide blocks 3 of the two large-roll clamping parts.
When the unreeling mechanism operates, the expansion and contraction of the air cylinder drives the two large-roll clamping parts to be far away from or close to each other so as to clamp and unload large rolls, and meanwhile, the large-roll clamping parts can clamp large rolls with different lengths and inner cylinder diameters by being matched with the first clamping head of the round table.
When the large roll is unwound, as shown in fig. 2, the turntable 1 rotates clockwise, so that the large roll 9 is tightly attached to the belt 8, when the large roll 9 is tightly attached to the belt 8, the large roll 9 is positioned in a gap between the two first roll bodies 7, the belt 7 can be slightly concave to increase friction force between the large roll and the belt, then the first roll bodies 7 rotate clockwise to drive the belt 8 to rotate clockwise to drive the large roll to rotate anticlockwise for unwinding, and the preservative film on the large roll 9 is led out from the attached side of the large roll and upwards and clockwise bypasses the upper end of the belt, and then enters a winding mechanism of the preservative film rewinding machine. In the unreeling process, the turntable rotates clockwise along with the extension of unreeling time, so that the large roll is always clung to the belt, in addition, in order to keep the unreeling efficiency consistent, the turntable and the first roller body can be arranged in a linkage manner, when the rotating angle of the turntable is increased, the rotating speed of the first roller body is also increased along with the increase, and the speed of unreeling the preservative film from the large roll is ensured to be stable, so that the subsequent reeling mechanism is used for reeling.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the invention. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
