Slitting machine for medicinal hard sheet of polyvinyl chloride (PVC) solid tablets

Abstract

The invention discloses a slitting machine for a medicinal hard sheet of polyvinyl chloride (PVC) solid tablets. The slitting machine for the hard sheet comprises a conveying assembly, wherein the conveying assembly comprises a bottom support, a power roller is arranged on the bottom support, a slitting shaft is also arranged on the bottom support, a feeding assembly is arranged on one side of theconveying assembly and comprises a feeding bottom support, an inclined support plate is disposed on the feeding bottom support, a sliding plate is arranged on the inclined support plate, a dedustingassembly is arranged above the slitting shaft and comprises a lower dust suction box, an upper dust suction box is arranged above the lower dust suction box, a sheet separation assembly is arranged onone side of the dedusting assembly, and a winding assembly is jointly arranged on the conveying assembly and the feeding assembly. The slitting machine has practical functions, adopts sliding tensiondischarge, is simple in structure, omits the structural design of the slitting machine, reduces the use cost, has good dedusting effects, has upper and lower dust suction boxes, effectively solves the problem of floating dust and slitting residue treatment, is provided with the sheet separation assembly, can rise and fall under automatic control and solves the problem of winding and overlapping of wounded rolls during winding.

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.
