Description

Technical Field

[0001] The utility model relates to the field of die cutting, in particular to a material collecting and releasing mechanism of a die cutting machine. Background Art

[0002] During the operation of the die-cutting machine, one coil is installed on one feeding shaft. As processing requirements change, multiple products need to be die-cut at the same time. However, due to the small size of some products, the width of the coil is narrow. It is necessary to put multiple coils on the same feeding shaft to achieve die-cutting of multiple products at one time. However, due to the limited die-cutting die area, the spacing between each coil is small. Due to the small spacing between each coil, the coils often interfere with each other when rotating, which affects the feeding speed, increases the working time, and reduces production efficiency. The coils often interfere with each other when rotating, causing the material belt pulled out of the coil to shake frequently.

[0003] Therefore, a material retracting and unreeling mechanism for a die-cutting machine is proposed, which can limit the rotation speed of multiple coils on the same axis so that they rotate synchronously and avoid mutual interference. Utility Model Content

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a material retracting and unwinding mechanism of a die-cutting machine, comprising: a beam, a fixed shaft, a plurality of first sleeves, a partition, a bracket, a second seat, a rotating shaft, a driving mechanism and a second sleeve, one end of the fixed shaft is fixed to the beam through the first seat, the first sleeves can be rotatably set on the fixed shaft, the partition corresponds to the first sleeve one by one, the partition is fixed to one end of the first sleeve close to the beam, the partition is set between adjacent coils, the second seat is set directly above the first seat through the bracket, the driving mechanism is set on the second seat, the rotating shaft can be rotatably set on the second seat, the rotating shaft is connected to the driving mechanism in a transmission manner, the second sleeve can be slidably set on the rotating shaft along the axis of the rotating shaft, the second sleeve rotates synchronously with the rotating shaft, and the outer peripheral surface of the second sleeve contacts with the upper end of the partition.

[0005] Preferably, the driving mechanism includes a servo motor, a first sprocket, a second sprocket, and a chain. The servo motor is arranged on the upper end surface of the second seat, the first sprocket is arranged on the motor shaft of the servo motor, the second sprocket is arranged on the rotating shaft, and the first sprocket and the second sprocket are connected through a chain transmission; when the axis of the rotating shaft is set horizontally, the chain is in a taut state.

[0006] Preferably, a plurality of protrusions are provided on the outer peripheral surface of the second sleeve, and through grooves are evenly spaced apart on the outer edge of the partition, and the protrusions are in clearance fit with the through grooves.

[0007] Preferably, the linear speed of the second sleeve is equal to the linear speed of the partition.

[0008] Preferably, the two rotating shafts are symmetrically arranged at the center of the second seat, and the axis of the fixed shaft is coplanar with the symmetry plane of the two rotating shafts.

[0009] Preferably, it further comprises a limiting member, which is detachably arranged on the outer peripheral surface of the second shaft, and which abuts against the end of the second sleeve, and is a permanent magnet.

[0010] Preferably, the second sleeve is a spline sleeve, the rotating shaft comprises a first shaft, a spline shaft and a second shaft, the first shaft, the spline shaft and the second shaft are fixedly connected in sequence, and the second sleeve is slidably arranged on the spline shaft.

[0011] Preferably, the rotating shaft further includes a first nut and a second nut, the first nut is threadedly connected to the first shaft, the second nut is threadedly connected to the second shaft, and two ends of the spline shaft abut against the first nut and the second nut respectively.

[0012] Preferably, it also includes a guide rail, two of which are symmetrically arranged inside the bracket, and two ends of the second seat are respectively slidably arranged on the two guide rails.

[0013] Preferably, the bracket is an inverted U-shaped plate.

[0014] The beneficial effects of the utility model are as follows: the coils are sequentially sleeved on the first sleeve, and the adjacent coils are separated by the partition. The second seat slides down under the influence of its own gravity and the rotating shaft, so that the second sleeve on the rotating shaft abuts against the upper end of the partition. The partition lifts up one end of the rotating shaft, and the other end of the rotating shaft is limited by a chain, so that the rotating shaft remains horizontal. When the rotating shaft rotates, the second sleeve will drive the partition to rotate. Since the partition is fixedly connected to the first sleeve, the first sleeve will rotate synchronously when the partition rotates.

[0015] Adjacent coils are separated by a partition, and the partition is driven by the second shaft sleeve to rotate synchronously with the first shaft sleeve, so that multiple coils on the same shaft can rotate synchronously without interfering with each other, thereby avoiding interference between multiple coils.
