AI Technical Summary

⚠Technical Problem

In existing technologies, it is laborious and inefficient for workers to pierce pork pieces with steel needles, and there is a risk of the steel needles pricking the workers' hands.

⚗Method used

A punching device for producing cured meat has been designed, including a liftable movable rod and a punching needle driven by a return spring. By rotating the pressure rod, the punching needle pierces the pork block and automatically retracts. The return spring's elasticity enables automatic resetting, simplifying operation and improving efficiency.

🎯Benefits of technology

It solves the problems of laborious and inefficient manual drilling, saves manpower, improves drilling efficiency, and avoids the risk of workers' hands being pricked.

Abstract

This utility model provides a punching device for producing cured meat, including a base, a mounting frame on the base, and a movable rod and a return spring abutting the movable rod on the mounting frame. The movable rod is vertically mounted on the mounting frame and located above the base. A punching needle is provided on the side of the movable rod near the base. The return spring abuts against the movable rod and drives it to move away from the base. The mounting frame also has a rotatable pressure rod with a protrusion that abuts against the end of the movable rod away from the base. When the pressure rod rotates, the protrusion pushes the movable rod towards the base. This utility model solves the technical problem of laborious and inefficient manual punching of pork pieces, resulting in labor saving and improved punching efficiency. Furthermore, it is simple to operate and avoids worker hand injuries during the punching process.
