Biodegradable membrane producing equipment

Abstract

The invention discloses biodegradable membrane producing equipment which structurally comprises transparent glass, a plasticizer box, an upper opening and closing door, a plastic groove, a cushion block, a lower opening and closing door, a degradation membrane anti-breakage device, a ventilation opening, a power line, a control panel, a ladder, an observation port and a large funnel. The plasticizer box is welded to the right end of the upper surface of the degradation membrane anti-breakage device, the transparent glass is embedded in the front surface of the plasticizer box, the large funnelis embedded into the left end of the upper surface of the degradation membrane anti-breakage device, the observation port is attached to the front surface of the large funnel, and the ladder is welded to the left surface of the degradation membrane anti-breakage device. The degradation membrane anti-breakage device is arranged to control the extrusion speed of thermoplastic and the transmission speed of a membrane conveying belt, the tensile force borne by the thin membrane can be within a bearable range, and the membrane is prevented from being broken by pulling due to excessive tension; anda plasticizer is added into raw materials, so that the toughness of the membrane is further improved, and the quality of products is ensured.

Description

technical field [0001] The invention is a biodegradable film production equipment, which belongs to the field of biodegradable film. Background technique [0002] Biodegradable mulch refers to a type of plastic mulch that can be degraded by microorganisms under natural environmental conditions. After microorganisms such as bacteria, fungi, and actinomycetes erode the plastic film, the polymer components are hydrolyzed, ionized or degraded due to the growth of cells. Protonization, mechanical damage occurs, and splits into oligomer fragments. When the current technology is used to produce biodegradable films, because the film extrusion speed is not easy to control, the film extrusion speed and the speed of the film transmission mechanism are different. Matching, the tension on the film exceeds its own tolerance range, and the film is prone to breakage and damage during transportation, which not only affects product quality, but also causes a certain amount of waste, indirectl...

Problems solved by technology

[0003] Aiming at the deficiencies in the existing technology, the purpose of the present invention is to provide a biodegradable film production equipment to solve the problem that the film extrusion molding speed is not easy to control when the current technical public equipment produces biodegradable films. The speed does not match the speed of the film transmission mechanism, so that the tension on the film exceeds its own tolerance range, and the film is prone to breakage and damage during the conveying process, which not only affects the product quality, but also causes a certain amount of waste, indirectly affecting the quality of the film. The question of economic efficiency
