The utility model discloses a special chain for a PVC glove production line with a single-side two-hand mode. This is achieved by setting the two sides of the inner link plate in the inner link of the chain body as right-angle bent plates, and each connecting and fixing a connecting plate with a transverse connecting shaft at its outer end through the bent plates. Due to the adoption of the connecting plate structure with the connecting shafts fixed on both sides of the bent plates, and two ceramic hand molds driven by the hand mold holders are installed on each connecting shaft, plus the adjustment of the outer width of the supporting roller, it not only ensures the chain support The roller runs smoothly in the C-shaped track, and realizes the setting of one-sided two-hand molds on the PVC glove production line. In this way, the area of the original production line can be used, and the product produced in the same production cycle can be twice that of the original equipment. Significantly improve work efficiency. And has the advantages of novel invention concept, scientific and reasonable design, simple and compact structure, reliable working performance, economical and practical, and broad application prospects.
PVC gloves are gloves made of polyvinyl chloride. They are free of allergens, powder-free, low dust generation, low ion content, free of plasticizers, grease, silicone, oil and other ingredients, and have strong chemical properties. Resistance, good flexibility and touch, anti-static, convenient and comfortable to wear, so it is widely used in labor protection and family health protection in the industries of sanitation inspection, food, chemical, electronics, pharmaceuticals, etc. The market demand is also quite large. The existing PVC glove production line is a chain that is looped into a circle driven by a power mechanism, and a ceramic hand mold fixed by a hand mold seat is installed on each side of the curved plate on both sides of the chain forming the chain. The ceramic hand mold follows The chain is dipped in PVC glue during the transmission process, and then dried to form a glove. Since only one ceramic hand mold can be installed on each side curved plate of the PVC glove production line, the production efficiency is low and the cost increases. With the economic development of society and the gradual improvement of living standards, people's demand for PVC-secondary gloves is also rising, and it is currently unable to meet the market demand. Therefore, how to improve labor productivity and meet market demand has become an urgent technical problem in the field of PVC glove processing.
[Summary of the invention]
The purpose of the utility model is to provide a special chain for a PVC glove production line with one-sided two-hand mode, which can significantly improve the processing efficiency of PVC gloves, meet market demand, and solve the problems existing in the prior art.
The technical scheme of the utility model is as follows: It includes a chain main body composed of inner chain links and outer chain links. In the inner chain links of the chain main body, both sides of the inner chain plate are right-angled bent plates, and are bent through the bends. Each board is connected and fixed by a connecting board with a transverse connecting shaft at its outer end.
The connecting plate is a plane with a rectangular top surface and a truncated cone shape in the middle. The plane is provided with smoothly transitioned 90° hemmings along the two corresponding sides of the length, and the wider end of the plane coincides with the inner link plate bent part. , And a connecting piece composed of a transverse through hole is provided at the flange of the narrower end.
The beneficial effects of the utility model: as the main body of the original chain is adopted, a connecting plate structure with connecting shafts in which the bent plates on both sides are respectively connected and fixed is set, and two hand mold seats are installed on each connecting shaft to drive it. The ceramic hand mold, coupled with the adjustment of the outer width of the roller, not only ensures the smooth operation of the chain roller in the C-shaped track, but also realizes the setting of the single-sided two-hand mold on the PVC glove production line. There is no need to increase the floor area, and the production efficiency is increased by more than 90% under the energy of the single-hand mold production line, so that the floor area of the original production line can be used, and the products produced in the same production cycle can be two of the original equipment. Times. The purpose of the invention is reliably achieved. And has the advantages of novel invention concept, scientific and reasonable design, simple and compact structure, reliable working performance, economical and practical, and broad application prospects.
