Pre-shrinking equipment for processing new material film

Abstract

The invention discloses pre-shrinking equipment for processing a new material film. The pre-shrinking equipment for processing the new material film structurally comprises a wind direction adjusting device, a shrinking body, a conveying belt and a bracket. The shrinking body is matched with the wind direction adjusting device and the conveying belt, and the bracket is arranged at the bottom of theshrinking body and is matched with the conveying belt. A fixing device, a supporting rod, a gear, a guide rail and a sliding block are mainly arranged in the shrinking body. The fixing device is matched with the sliding block through the supporting rod, the inner side of the sliding block is of a rack structure and is matched with the gear in a meshing connection mode, and the gear is connected with the guide rail in a sliding fit mode. Corresponding acting force is generated on a handle and an elastic piece of the fixing device through the relative rotation of the gear and the sliding block,so that a fixed block deforms, a clamping device fixes the product, it is guaranteed that the film tightly covers the accurate position of the product or a packaging piece after being heated and shrunk, and the film covering accuracy is improved.

Description

technical field [0001] The invention relates to the field of film processing, in particular, it is a pre-shrinking device for new material film processing. Background technique [0002] TPU is an environmentally friendly high molecular polymer. It overcomes many defects of PVC and PU leather. It not only has most of the characteristics of rubber and ordinary plastics, but also has excellent comprehensive physical and chemical properties, so it is also called future materials. TPU The film is a film made of TPU pellets through a special process. It inherits the excellent physical properties of TPU and has a wide range of applications. Due to the advantages of non-toxicity and environmental protection requirements, TPU film products such as TPU cloth are widely used shoe uppers, table mats, handbags, luggage and handicrafts and other fields. [0003] Existing pre-shrinking equipment cannot ensure that when the shrink film is printed with characters or patterns, it will be tig...

AI Technical Summary

Problems solved by technology

[0005] For the above-mentioned existing pre-shrinking equipment, when the shrink film is printed with fonts or patterns, it cannot guarantee that it will be tightly covered on the exact position of the product or package after being heated and shrunk, resulting in deviation of the font or pattern, which increases the cost and makes it difficult to achieve printing shrinkage Mass production of film packaging products; and the wind direction of the air outlet of the shrinking equipment is fixed. When the item is irregular in shape, the plastic film wrapped on the packaged item shrinks unevenly, so that the plastic film cannot be completely wrapped after heating and shrinking Articles, so that the packaging effect of plastic film is poor, the invention provides a kind of pre-shrinking equipment for new material film processing
