Rotary bit change type rubber sieve perforating machine

Abstract

A rotary bit change type rubber sieve perforating machine overcomes the defects that rubber sieves are manually perforated in most cases in laboratories in the prior art, time and labor are wasted, perforators have too many models and are prone to loss, rubber sieve perforating machines in the existing patented technology are not efficient, and drill bits are troublesome to replace. The rotary bit change type rubber sieve perforating machine is characterized in that two identical sliding grooves are formed in the inner wall of a machine enclosure, a round hole is formed in the right sidewall of the machine enclosure, the left end and the right end of a baffle are connected with a spring b and a motor respectively, a rotor of the motor is connected with a rotary rod, the rotary rod is cylindrical, a supporting plate is arranged at the lower end of the rotary rod, a disc is arranged on the supporting plate, a knob penetrates through the sidewall of the disc, a plurality of dials are arranged at the upper end of the disc, a plurality of drill bits with different diameters are arranged at the lower end of the disc, the front end and the rear end of the inner wall of the machine enclosure are connected with two identical springs a respectively, the other ends of the springs a are connected with two identical partition plates respectively, one end of a brace is connected to the inner wall of the machine enclosure, and a storage plate is arranged at the bottom end of the machine enclosure. The rotary bit change type rubber sieve perforating machine is simple in design, convenient to use, low in cost and easy to popularize.

Description

technical field [0001] The invention relates to chemical experiment instruments and equipment, in particular to the field of a rotary head-changing rubber sieve punching machine. Background technique [0002] In the laboratory, manpower is often used to punch holes for rubber sieves, which is time-consuming and labor-intensive. There are too many types of punches and they are easy to be lost. The existing patented technology of rubber sieve punching machines has the disadvantages of inefficiency and troublesome turning around. Contents of the invention [0003] The purpose of this design is in order to overcome the above-mentioned defective of prior art, and a kind of rotary head-changing type rubber sieve punching machine that provides. [0004] Technical solutions: [0005] This design is composed of chute, baffle, round hole, casing, spring a, pillar, placement plate, partition, drill bit, disc, rotating rod, motor, spring b, hook, knob, support plate, dial, Both the ...
