Modularly-designed multi-functional bag making machine

Abstract

The invention discloses a modularly-designed multi-functional bag making machine which comprises a thin film discharging mechanism, a zipper discharging mechanism, a thin film and zipper welding mechanism, a welding handle mechanism, a servo punching mechanism, an up-down ironing mechanism, a cutter mechanism, a rotary arm collecting mechanism and a bag arranging and conveying mechanism. A thin film folding mechanism, a rear material pulling traction component and an edge bottom folding mechanism are arranged between the thin film discharging mechanism and the thin film and zipper welding mechanism. A zipper traction mechanism is arranged between the zipper discharging mechanism and the thin film and zipper welding mechanism, and a front material pulling traction component is arranged at the output end of the thin film and zipper welding mechanism. The rear material pulling traction component is arranged at the feeding end of the welding handle mechanism, a middle material pulling traction component is arranged between the welding handle mechanism and the punching mechanism, and the front material pulling traction component is arranged between the up-down ironing mechanism and the cutter mechanism. The bag making machine is used for manufacturing and producing diaper bags, hand bags, zippered bags and the like, the bag manufacturing quality is guaranteed, efficient and stable operation of the equipment is achieved, and meanwhile simple bag arranging and conveying are achieved on the premise of high-speed bag making.

Description

technical field [0001] The invention relates to a bag-making equipment for plastic film bags, in particular to a multifunctional bag-making machine. Background technique [0002] Plastic film bags are widely used in the market, and plastic bags come in various styles, such as diaper bags, handbags, zipper bags, etc. Some of these bags have zippers, some have handles, some need to be perforated, some have gussets and cuffs, the list goes on and on. How can finish the production of above-mentioned all functional bags simply in structure is the technical problem that present manufacturer needs to solve. In addition, the bag-making equipment of the prior art has the following deficiencies: 1. When the bag has a zipper, the plastic film and the zipper will be welded together in the bag-making production process. The current welding technology of the plastic film and the zipper is generally not It is the electric heating knife that sets a certain temperature for production. When...

AI Technical Summary

Problems solved by technology

In addition, the bag-making equipment of the prior art has the following deficiencies: 1. When the bag has a zipper, the plastic film and the zipper will be welded together during the bag-making production process. It is the electric heating knife that sets a temperature for production. When the film pulling speed is accelerated, the welding temperature between the film and the zipper will be insufficient, and the welding will not be firm; and the film pulling speed will be slowed down, which will lead to excessive welding, and it is easy to produce waste products.

2. When the bag needs to be punched, the punching mechanism of the traditional bag making machine generally uses the punching cylinder to push the punching punch to perform the punching action, which is limited by the operating speed of the cylinder and the cylinder ventilation control solenoid valve, which cannot meet the high-speed punching. There are disadvantages of slow punching speed and high operating noise; in addition, if the left and right position of film conveying changes during the punching process, it will not be able to punch holes accurately, and the quality of bag production cannot be guaranteed.

3. The upper and lower ironing mechanisms of the current bag making machine, the upper and lower copper knives are driven by the cylinder, the speed is slow, the working noise is large, and the welding pressure is also small, all of which affect the increase in the production speed of the bag making machine

4. Under the premise of high-speed bag making, it is difficult to realize simple bag sorting and sending
