[0031] In the above technical solution, the bracket serves as the supporting foundation for the overall automatic roller loading mechanism. Automatic roller loading is achieved through the coordinated operation of the roller loading assembly, the unloading assembly, and the receiving shaft assembly. In the roller loading assembly, the roller drive pushes the arm connecting plate, causing the roller arm to rotate around the bracket. A slot is used to hold the take-up roller, and a clamping mechanism secures it. In the unloading assembly, the unloading drive drives the receiving arm to rotate, with its curved section receiving the take-up roller. In the receiving shaft assembly, a rotary drive drives the turntable transmission shaft, which in turn drives the turntable via a pulley, causing the material shaft receiving plate fixed on the turntable to rotate. The concave surface of the material shaft receiving plate is used to receive and transfer the take-up roller. This system enables an automatic roller loading process. Each component has a clear division of labor and works in close coordination, greatly improving the automation level of take-up roller replacement in blown film production, reducing manual intervention, lowering labor intensity, and increasing production efficiency.

[0032] The upper roller drive and the lower roller drive are both pneumatic cylinders.

[0033] Its specific working principle is as follows:

[0034] The automatic roll loading process begins with placing the spare take-up roll into the slot of the roll loading assembly. At this point, the roll loading drive is activated, its output pushing the boom connecting plate. Since one end of the roll boom is rotatably connected to the support, the movement of the boom connecting plate causes the roll boom to rotate around the support towards the unloading assembly. After reaching the desired position, the clamping mechanism (such as a clamping cylinder) actuates, its output lever retracts, releasing the clamping and fixing of the take-up roll. Under gravity, the take-up roll slides down the slot into the bend of the unloading assembly.

[0035] Next, the unloading roller drive in the unloading roller assembly starts working, and its output end drives the receiving swing arm to rotate. The receiving swing arm drives the take-up roller placed in the bend to rotate together. The rotation drive of the receiving shaft assembly (consisting of a drive motor and a reducer) starts. The output power of the drive motor is reduced and amplified by the reducer and then transmitted to the turntable drive shaft. The turntable drive shaft drives the turntable to rotate through the pulley drive connection, which in turn causes the material shaft receiving plate fixed on the turntable to rotate. The material shaft receiving plate rotates towards the take-up arm side.

[0036] When the receiving arm rotates to the appropriate position, the take-up roller slides down onto the concave surface of the material shaft receiving plate under gravity. Then, the rotary drive continues to work, driving the turntable and material shaft receiving plate to rotate further towards the take-up arm, finally using gravity to slide the take-up roller onto the take-up arm, completing the automatic roller loading process. Throughout the process, the components work together in a set sequence and manner, realizing automated operation from the placement of the spare take-up roller to its final installation on the take-up arm, greatly improving the efficiency and automation of take-up roller replacement in blown film production.

[0037] Specifically, the pressing mechanism is a pressing cylinder 31, the pressing cylinder 31 is fixed on the side of the clamping groove, the output end of the pressing cylinder is connected with a pressing rod 32, and a through hole 33 for the pressing rod to pass through is arranged on the side wall of the clamping groove.

[0038] In the embodiment, the pressing mechanism is a pressing cylinder, which is fixed on the side of the clamping groove. When the pressing cylinder is started, the pressing rod at the output end of the pressing cylinder passes through the through hole in the side wall of the clamping groove, so as to press and fix the winding roller in the clamping groove, thereby preventing the winding roller from being displaced during the transfer process.

[0039] Specifically, the rotating driving member comprises a driving motor 34 and a speed reducer 13 connected with the output end of the driving motor 34, and the output end of the speed reducer 13 is connected with the rotating shaft of the rotating disc.

[0040] In the embodiment, the rotating driving member is composed of a driving motor and a speed reducer. The driving motor outputs power, the speed reducer reduces the received motor power and amplifies the torque, and then transmits the power to the rotating shaft of the rotating disc, so that the rotating shaft of the rotating disc rotates at a proper rotating speed and torque, and then drives the rotating disc and the material shaft connecting plate to rotate.

[0041] Specifically, a supporting shaft 35 is arranged between the material shaft connecting plates.

[0042] In the embodiment, the supporting shaft is used for supporting the film when the material shaft connecting plate rotates, so as to facilitate the cutting action of the cutter.

[0043] Specifically, the cutting assembly comprises a cylinder mounting plate 36 fixed on the support, a cutter cylinder 37 fixed on the cylinder mounting plate, a cutter cylinder mounting plate 38 connected with the output end of the cutter cylinder, a rodless cylinder 39 fixedly installed on the cutter cylinder mounting plate, a flying cutter mounting plate 40 connected with the rodless cylinder, and a flying cutter installed on the flying cutter mounting plate.

[0044] In the embodiment, the cutting assembly is installed on the active material winding roller, the cutter cylinder is fixed on the cylinder mounting plate, the cutter cylinder mounting plate is pushed when the cutter cylinder is started, the rodless cylinder is installed on the cutter cylinder mounting plate, the rodless cylinder drives the flying cutter mounting plate and the flying cutter installed thereon to move, and the cutting operation on the blown film product is realized.

[0045] Specifically: further comprising a discharging assembly, the discharging assembly comprises a rotating shaft one 5 rotatably connected with the support, a receiving arm 6 connected with the rotating shaft one 5, a driving component one 7 driving the receiving arm 6 to rotate around the axis of the rotating shaft one, a rotating shaft two 8 rotatably connected with the support, a discharging arm 9 connected with the rotating shaft two, and a driving component two 10 driving the discharging arm 9 to rotate around the axis of the rotating shaft two, the upper end of the receiving arm is provided with a groove 11 for positioning both ends of the winding roller, the side wall of the groove 11 near the active receiving roller side is higher than the other side wall and is provided as a limiting part 12, and the upper end of the discharging arm is provided with an arc-shaped concave surface 14 for catching both ends of the winding roller, and the arc-shaped concave surface 14 away from the side of the active receiving roller has a material receiving extension part 15.

[0046] The receiving support plates on both sides of the support are provided with support planes 18 connected with both ends of the winding roller.

[0047] In the embodiment, the discharging assembly realizes the automatic discharging process of the winding roller after completing winding, and the cooperative operation of the receiving arm and the discharging arm makes the transfer and discharging process of the winding roller smooth and accurate, and improves the automation degree of the film blowing production.

[0048] The specific principle is that when the winding roller needs to be discharged after completing winding, the driving component one drives the receiving arm to rotate to the side of the discharging arm until the winding roller is pushed to the end of the support plane as shown in the figure. Figure 3 Simultaneously, the driving component two drives the discharging arm to rotate to the side of the winding roller, and when the winding roller continues to be pushed forward, the winding roller falls on the arc-shaped concave surface of the discharging arm after losing the support of the support plane. After the discharging arm receives the material, the discharging arm is driven by the driving component two to rotate to the ground side until the discharging is completed. The winding roller discharged from the material receiving extension part rolls onto the ground.
