Punching device for manufacturing paper products

Abstract

The invention relates to a punching device for manufacturing paper products. The punching device comprises a base, a driving chamber, a bracket, a punching pin, a rack, a transmission shaft, a slide rail, an electric motor, a slide block, a connecting spring, a connecting column, a pressurizing spring, a protective jacket and an incomplete gear, wherein the bracket is arranged at the top end of the base; the slide block is connected to the front end surface of the slide rail in a sliding manner; the rack is fixedly arranged at the front end of the slide block; the connecting spring is tightlyconnected with the top end surface of the slide block; the transmission shaft is fixedly connected with the output end of the electric motor; the connecting column is fixedly arranged at the bottom end of the rack, penetrates through the driving chamber, and extends to the lower side of the driving chamber; the bottom end of the connecting column is tightly connected with the punching pin by meansof the pressuring spring; the protective jacket is fixedly arranged at the lower end of the connecting column, and is arranged on the outer side of the pressurizing spring in a sleeving manner; and the incomplete gear is mounted on the transmission shaft. Through the adoption of the design, the punching pin is driven to move up and down by using a gear and rack transmission principle so as to punch the paper products, and the punching device is excellent in structure and low in rate of finished products.

Description

technical field [0001] The invention relates to the field of paper product processing equipment, in particular to a punching device for paper product manufacturing. Background technique [0002] Paper product manufacturing: refers to the production activities that use paper and cardboard as raw materials and further process them into paper products. The advantages are: high cost performance, good elasticity and toughness. After nearly 30 years of development, China's paper product packaging industry has now reached the mid-stage of industrialization, and the prototype of large-scale and intensive development has been formed. In recent years, with the gradual subsidence of the financial crisis, the foreign paper product packaging market has recovered; at the same time, some Chinese paper product packaging export enterprises have transformed from export sales to domestic sales, and domestic policies have vigorously supported the paper product packaging industry. development s...
