Packing bag punching equipment

Abstract

The invention provides a packaging bag punching device, which relates to the technical field of packaging bag punching, including a base, a transmission mechanism, a punching mechanism and a support seat fixedly connected to the top of the base. The transmission mechanism is set on the support seat, and the punching mechanism includes an upper fixed block, a lower moving block, a circular dial and a punching needle arranged on the annular dial, and several elastic parts are arranged between the upper fixed block and the lower moving block , the upper fixed block is fixed on the lower end of the support seat, and the annular needle disc is connected to the lower end of the lower moving block; when punching, the elastic member instantly drives the lower moving block to drive the punching hole on the annular needle disc to punch the packaging bag on the transmission mechanism hole. Through the implementation of this technical solution, it is possible to effectively avoid the phenomenon of rough edges or out-of-roundness in the punching in the prior art, and improve the punching quality of the packaging bag; and it can also produce packaging bags with different apertures at the same time, improving the efficiency of punching the packaging bag .

Description

technical field [0001] The invention relates to the field of packaging bag punching technology, in particular to a packaging bag punching device. Background technique [0002] Packaging bags refer to bags used to pack various supplies, which make the goods convenient to transport and store during the production and circulation process, and are widely used in daily life and industrial production. Actual figures show that 80% of used plastic bags are eventually transported to landfills for disposal like general garbage, and only 7% of plastics are recycled. Combining various materials with different characteristics to improve the air permeability, moisture permeability, oil resistance, water resistance, and chemical resistance of the packaging material, so as to make it play an anti-insect, dust-proof, anti-microbial, anti-light, fragrance, and odor Odor insulation, heat resistance, cold resistance, impact resistance have better mechanical strength and processing applicabilit...

Problems solved by technology

[0003] However, the traditional method of punching a packaging bag is to manually use two steel needles to punch holes in a dozen packaging bags. Due to the slow punching speed in the traditional punching machine, there is a common problem of uneven punching in the bag making machine, which makes the punching uneven and deviated, which affects the bag making quality of the bag making machine; in addition, when the punching needle In the event of damage, the entire indenter needs to be disassembled and replaced, which is time-consuming and laborious, directly affecting the work efficiency of the enterprise

At present, most of the punch devices in the film feeding part of packaging machines in the same industry in the market use a combination of rubberized shafts and needle punchers. The cam rotation mechanism is used to control the distance between the puncher needles and the rubberized shafts to achieve For the purpose of easy film penetration and punching, this kind of cam rotation structure has the problem that the moving speed of the punching needle is slow, and there are often burrs or out-of-round punching holes that affect product quality.

Therefore, in view of the deficiencies in the prior art, it is urgent to study a method to improve the punching speed of packaging bags, avoid punching unevenness, deviation, and affect the bag making quality of the bag making machine; and can be quickly disassembled and replaced as needed. Hole needles to improve the efficiency of punching bags
