Description

An adjustable plastic film feeding and unloading device Technical Field

[0001] This utility model belongs to the field of plastic film handling technology, specifically an adjustable plastic film handling device. Background Technology

[0002] Plastic film is a type of plastic product with a certain thickness, width, and length, made from polymer synthetic materials as the main raw material, mixed with other auxiliary materials in a certain proportion, and processed by plastic molding machinery. It has a flat, smooth, and soft surface, and features light weight, high transparency, moisture resistance, and good barrier properties. It is widely used in agriculture, industry, daily life, and many other fields. In the processing of plastic film, winding equipment is usually required. It is mainly used to wind and arrange the produced plastic film for subsequent storage, transportation, and use.

[0003] Currently, there is an adjustable plastic film handling equipment, but it still has shortcomings in actual use. The most obvious one is that during the plastic film handling process, a tension roller is usually required to provide tension for the film handling. However, on some handling equipment, the tension roller requires the operator to rotate the bolts at both ends to adjust its position, which can easily lead to differences in the rotation angle and displacement of the bolts, reducing the working efficiency of the handling equipment. Therefore, we propose an adjustable plastic film handling equipment. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable plastic film feeding and receiving device to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] Specifically, this application describes an adjustable plastic film receiving and discharging device, comprising: an installation platform and a fixed frame fixedly connected to both ends of the top of the installation platform; the installation platform is provided with a rotating component for receiving and discharging the film; and the side wall of the fixed frame is provided with an adjusting component for correcting the deviation of the film.

[0007] A mounting frame is fixedly connected to one bottom end of the fixed frame. A movable plate is slidably connected to the inner side wall of the mounting frame. Movable rods are fixedly connected to both ends of the top of the movable plate. The top end of the movable rod passes through the top of the inner cavity of the mounting frame and the bottom of the fixed frame, and is fixedly connected to a second support block. A tension roller is rotatably connected between two sets of second support blocks via bearings. A magnetic powder controller is fixedly connected to the side wall of one set of second support blocks. The magnetic powder controller works in conjunction with the tension roller. A screw is rotatably connected between the top and bottom of the inner cavity of the mounting frame. The screw is threadedly connected to the movable plate.

[0008] As a preferred technical solution of this application, the rotating component includes a take-up roller, and a fixed frame is fixedly connected to both ends of the top of the mounting platform. A first support block is fixedly connected to the top of the fixed frame, and a take-up roller is rotatably connected between two sets of the first support blocks.

[0009] As a preferred technical solution of this application, a motor for driving the winding roller to rotate is fixedly connected to the side wall of the first support block.

[0010] As a preferred technical solution of this application, the adjusting component includes two sets of hydraulic cylinders, which are respectively fixedly connected to both sides of the fixed frame. The power output end of the hydraulic cylinder passes through the side wall of the fixed frame and is fixedly connected to a support rod. The outer side wall of the support rod is rotatably connected to a rotating rod through a damping bearing. The side wall of the rotating rod is rotatably connected to a rotating shaft. One end of the rotating shaft is fixedly connected to a connecting plate. The side wall of the connecting plate is rotatably connected to a correction head.

[0011] As a preferred technical solution of this application, multiple sets of support rollers are rotatably connected between the inner sidewalls of the fixing frame.

[0012] As a preferred technical solution of this application, a turntable for driving the screw to rotate is fixedly connected to the bottom of the mounting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the scheme of this application:

[0015] 1. By setting an installation frame at the bottom of the fixed frame, and rotating a screw inside the installation frame to connect a movable plate via the screw thread, the movable plate slides within the installation frame. The movable plate supports a movable rod, which fixes the second support block and tension roller. By driving the screw to rotate, the screw drives the movable plate and movable rod to move longitudinally. The movable rod then drives the second support block and tension roller to move longitudinally, causing the tension roller to contact the plastic film. A magnetic powder controller is installed on the second support block to increase the tension on the plastic film. Thus, by driving the screw to rotate, the positions of the second support blocks at both ends are synchronously adjusted, improving the working efficiency of the take-up and release equipment.

[0016] 2. By installing a hydraulic cylinder on the fixed frame, the hydraulic cylinder drives the support rod to move horizontally. The support rod rotates to support the rotating rod, which in turn supports the rotating shaft and the connecting plate. The alignment head is installed on the connecting plate, allowing the hydraulic cylinder to drive the alignment head to move horizontally. This enables the plastic film to be adjusted left and right for easy use. Attached Figure Description
