Embodiment 1

[0028] A process for utilizing waste plastics to regenerate plastic woven bags, comprising the following steps:

[0029] (1) Classify the collected waste plastics and perform pretreatment. Place the waste plastics in clean water under 600-800W ultrasonic power for cleaning. After cleaning, put them into a centrifuge and process them at a speed of 2000r / min for 10-15 minutes. ;

[0030] (2) After the pretreatment is completed, crush the waste plastics into 1-1.5cm plastic fragments, and then put the crushed fragments into the cleaning solution for 20-40min. The cleaning solution consists of water, 10mol / Acetic acid with a concentration of L and hydrochloric acid with a concentration of 12mol / L are composed according to the volume ratio of 100:10:10; stir during the soaking process, rinse with water for 5 minutes after completion, and then put it into a centrifuge, the temperature is controlled at 60-80°C, Process at a speed of 2000r / min for 15-20 minutes to obtain crushed raw...

Embodiment 2

[0036] On the basis of Example 1, such as Figure 1-5As shown; after the woven material is cut, the cut edge needs to be hemmed. In the prior art, the cut material is directly input to the conveyor belt, and the conveyor belt is used to transport the cut material to the hemming machine. In this process , the cutting material lacks positioning during the conveying process of the stitched side, and it is easy to cause the stitching side to deviate during conveying, so it is necessary to perform side-to-side operations, which affects production efficiency. Therefore, an integrated cutting and seaming machine is set up, which includes : device support 1, the upper part of the device support 1 is provided with a material roll feeding table 2, and one side of the material roll feeding table 2 is equipped with a feed pair roller 3;

[0037] A first drive shaft 12 and a second drive shaft 13 are installed on the device support 1, the first drive shaft 12 is driven by a stepper motor 1...

Embodiment 3

[0042] On the basis of Example 2, such as Figure 4 As shown; the upper part of the cutter plate 33 is fixed with a column 51, the column 51 is slidably inserted into the cutter frame 31, the column 51 is perpendicular to the cutter plate 33, the limit spring 52 is installed on the bottom of the cutter plate 33, and the bottom of the limit spring 52 is fixed Bead 53 is arranged, and bead 53 is positioned at backing plate 37 tops.

[0043] When the cutter plate 33 moved down, the bead 53 contacted the braided material in advance, and when the electric push rod 21 stretched out, it squeezed the limit spring 52, so that the bead 53 extruded the backing plate 37, thereby realizing pre-fixing of the braided material, preventing After the braid is cut, the ends of the braid fall off.

Abstract

The invention relates to a process for regenerating a plastic woven bag by utilizing waste plastics. The process for regenerating the plastic woven bag by utilizing the waste plastics comprises the following steps: putting the waste plastics in an ultrasonic environment in advance; pre-cleaning soil on the surfaces of the waste plastics by using ultrasonic waves; performing shearing after the cleaning is completed; and putting the sheared material into a cleaning solution containing hydrochloric acid and acetic acid, so that acetic acid and hydrochloric acid in the cleaning solution can reactwith the soil on the surfaces of the waste plastics after being diluted, calcium carbonate in the soil is corroded, and the surfaces of the waste plastics are further cleaned; and therefore, the content of soil mixed into the waste plastics during production of the plastic woven bag is reduced, and the production quality of the plastic woven bag is improved.

Description

technical field [0001] The invention relates to the technical field of production of plastic woven bags, in particular to a process for utilizing waste plastics to regenerate plastic woven bags. Background technique [0002] Plastic woven bag, also known as snakeskin bag. It is a kind of plastic bag, used for packaging, and its raw materials are generally various chemical plastic raw materials such as PP and PE. There are 6 billion woven bags used for cement packaging in my country every year, accounting for more than 85% of the bulk cement packaging. In addition to being used for cement packaging, plastic woven container bags are widely used in industrial and agricultural product packaging, aquatic product packaging, and poultry feed packaging; therefore, the market demand for plastic woven bags is still very large. Batch production will result in a large amount of plastic, and raw material resources and prices will gradually become a problem, which will not only increase...
