Description

TECHNICAL FIELD

[0001] The utility model relates to ton bag processing technical field, concretely is a kind of plastic film stretching device. BACKGROUND

[0002] Ton bag is usually made of high-strength polypropylene (PP) or polyethylene (PE) and other plastic woven cloth. These woven cloths are processed by wire drawing, weaving and other processes, and have high strength and toughness, which can withstand the weight of materials and external force during loading and unloading.

[0003] At present, in the prior art, dust, impurities and other pollutants on the surface of the film can cause uneven stretching during stretching. Impurity particles can cause the film to be subjected to uneven stress in local areas, resulting in inconsistent film thickness, partial thinning and even holes. In view of this, we propose a plastic film stretching device. UTILITY MODEL CONTENT

[0004] The main purpose of the utility model is to provide a plastic film stretching device, which can solve the problems raised in the background art.

[0005] To achieve the above purpose, the utility model provides a plastic film stretching device, which comprises a support, a motor is arranged on the outer wall of the support, a conveyor belt is drivingly connected to the motor, a stretching roller is rotatably connected to the conveyor belt, a cleaning assembly is arranged on the support, and the cleaning assembly is movably connected to an anti-wrinkle assembly.

[0006] A transmission wheel is drivingly connected to the conveyor belt, and a rotating rod is fixedly connected to the transmission wheel.

[0007] A cleaning cylinder is fixedly connected to the rotating rod, and a bristle structure is arranged on the surface of the cleaning cylinder.

[0008] Preferably, the anti-wrinkle assembly comprises a transmission belt, the rotating rod is drivingly connected to a reciprocating screw rod through the transmission belt, and the rotating rod transmits power to the reciprocating screw rod through the transmission belt to start rotating the reciprocating screw rod.

[0009] Preferably, the outer wall of the support is fixedly connected with a mounting seat, and the mounting seat is provided with a reciprocating screw rod.

[0010] Preferably, the reciprocating screw rod is threadedly connected with a sliding ring, and the sliding ring is fixedly connected with a sliding seat. When the reciprocating screw rod rotates, the sliding ring threadedly connected therewith moves linearly along the reciprocating screw rod under the limitation of the mounting seat.

[0011] Preferably, the sliding seat is rotatably connected to a roller, which is positioned below the ton bag. When the sliding seat makes a reciprocating linear motion, the roller will roll back and forth under the ton bag. After passing the stretching roller, the ton bag tends to wrinkle. The back and forth rolling of the roller can smooth out the ton bag and prevent wrinkles from forming.

[0012] Preferably, the cleaning component is located in front of the stretching roller, and the anti-wrinkle component is located behind the stretching roller.

[0013] This invention provides a plastic film stretching device. It has the following advantages:

[0014] (1) The plastic film stretching device uses a cleaning component to transmit the motion of the conveyor belt to the drive wheel, causing the drive wheel to start rotating. The rotating rod will rotate with the drive wheel. As the cleaning cylinder rotates, the film passes through the cleaning cylinder before passing the stretching roller. The bristle structure will contact the surface of the ton bag film. As the cleaning cylinder continues to rotate, the bristle structure continuously cleans the film surface, ensuring that the film surface is as clean as possible before entering the stretching process. Through the rotation of the cleaning cylinder and the cleaning of the bristle structure, most of the contaminants on the film surface can be removed, which helps to improve the stretching quality and reduce film defects caused by impurities.

[0015] (2) The plastic film stretching device uses an anti-wrinkle component. The rotating rod transmits power to the reciprocating screw through the transmission belt, causing the reciprocating screw to start rotating. When the reciprocating screw rotates, the sliding ring connected to it by the thread will move back and forth along the reciprocating screw under the limit of the mounting seat. When the sliding seat moves back and forth, the roller will roll back and forth under the ton bag. The ton bag tends to wrinkle after passing through the stretching roller. The back and forth rolling of the roller can smooth the ton bag. By applying uniform pressure, the possible wrinkles can be smoothed, ensuring that the surface of the ton bag is flat and improving product quality. Attached Figure Description
