Vertical conveying mechanism for film rolls

Abstract

The invention discloses a vertical conveying mechanism for film rolls, and belongs to the technical field of thin film processing machinery equipment. The mechanism comprises a fixed base, a roll bearing circular plate, limiting plate clamps, a roll clamping mechanism and a film guiding mechanism, wherein the middle of the lower side of the roll bearing circular plate is rotationally connected to the fixed base, the multiple limiting plate clamps are symmetrically arranged on the fixed base on the outer side of the roll bearing circular plate in the radial direction of the roll bearing circular plate, the roll clamping mechanism is vertically arranged in the middle of the upper side of the roll bearing circular plate, the film guiding mechanism is vertically arranged on one side of the upper part of the fixed base, damping mechanisms are horizontally arranged on two limiting plate clamps which are arranged on the fixed base in the radial direction of the roll bearing circular plate, and each damping mechanism comprises a lifting damping rod, a lifting guide block, a translation guide block, a translation cylinder and a translation support. The mechanism is reasonable in structural design and can stably, efficiently and accurately unwind and convey the film rolls in the vertical direction. The efficiency and the quality of film unwinding and conveying are improved, and the requirements of production and use are met.

Description

technical field [0001] The invention belongs to the field of film processing machinery and equipment, and in particular relates to a film roll vertical transmission mechanism. Background technique [0002] At present, films are more and more widely used in our production and life. Films are generally made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as a coating layer , plastic packaging and plastic packaging products are taking an increasing share in the market, and have been widely used in food, medicine, chemical and other fields, among which food packaging accounts for the largest proportion, such as beverage packaging, quick-frozen food packaging, Cooked food packaging, fast food packaging, etc., have brought great convenience to people's lives.

AI Technical Summary

Problems solved by technology

During the production and processing of the existing film, the film roll needs to be unwound and conveyed, so that the film can be processed according to the needs during the conveying process. The existing film conveying mechanism generally places the film roll horizontally and then transmits it horizontally. , so that the film can be transported horizontally according to the needs and then processed in the next process. However, in the field of production and processing such as wrapping and winding with films, the horizontal transport of the film is difficult to meet the needs of use, and the film needs to be transported vertically. Existing The film vertical conveying mechanism of our company only places the film roll vertically on a circular plate that can rotate horizontally, and uses the pulling of the film to make the circular plate rotate to unwind and transport the film roll. It is difficult for the film roll to be stable during the whole process. Accurate unwinding, the circular plate will rotate excessively due to the rotational inertia during the rotation process, causing the film on the film roll to loosen, and the existing film roll will also be pulled by the film when it is placed vertically on the circular plate As a result, the film roll is tilted and fallen, making it difficult to transport the film roll vertically smoothly and accurately, which cannot meet the needs of production and use.
