A hard tablet cutting machine for polyvinyl chloride solid tablets

Abstract

The invention discloses a pharmaceutical hard sheet cutting machine for polyvinyl chloride solid tablets. The hard sheet cutting machine includes a conveying assembly, and the conveying assembly includes a bottom bracket. The bottom bracket is equipped with a power roller, and the bottom bracket is also equipped with a Slitting shaft, feeding assembly is installed on one side of the conveying assembly, the feeding assembly includes feeding bottom support, an inclined support plate is provided on the feeding bottom support, a slide plate is installed on the inclined support plate, and a dust removal assembly is installed above the cutting shaft , the dust removal assembly includes a lower dust collection box, an upper dust collection box is arranged above the lower dust collection box, a slice assembly is provided on one side of the dust removal assembly, and a winding assembly is provided on the conveying assembly and the feeding assembly. The invention has practical functions, adopts sliding and tensioning discharge, has a simple structure, saves the structural design of the slitting machine, reduces the use cost, and has good dust removal effect. There are two sets of dust collection boxes on the upper and lower sides, which effectively solves the problem of floating dust and cutting. To deal with the problem of slag, there is a split component, which can automatically control the lifting, and solves the problem of winding and overlapping of the rewinding roll during rewinding.

Description

technical field [0001] The invention relates to the field of polyvinyl chloride production, in particular to a hard sheet cutting machine for polyvinyl chloride solid tablets. Background technique [0002] Polyvinyl chloride, referred to as PVC (Polyvinyl chloride), is a vinyl chloride monomer (vinyl chloridemonomer, referred to as VCM) in peroxides, azo compounds and other initiators; or under the action of light and heat, it can be polymerized according to the mechanism of free radical polymerization. made polymer. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. PVC is a white powder with an amorphous structure, a small degree of branching, a relative density of about 1.4, a glass transition temperature of 77-90°C, and begins to decompose at about 170°C [1], and has poor stability to light and heat. After long-term sunlight exposure, it will decompose to produce hydrogen chloride, and further autocatalyze t...

Problems solved by technology

Polyvinyl chloride solid tablet medical rigid tablet is a kind of aluminum-plastic outer packaging material for solid preparations, which is compounded with aluminum-based film to form a complete solid tablet or capsule outer packaging material. Slitting is required before use. The existing slitters have poor slitting effect and no dust removal function. After slitting, winding is easy to repeat and mix, resulting in high cost and heavy environmental pollution. In view of this situation, a new method is proposed.
