Description

Technical Field

[0001] This utility model relates to the technical field of plastic extrusion and drawing, and in particular to a plastic extrusion and drawing device for the production of plastic packaging bags. Background Technology

[0002] The production process of woven plastic packaging bags first requires the extrusion and drawing device to produce flat plastic ribbons, which are then woven together to form plastic packaging bags. In the prior art, utility model patent application number 202022990197.1 discloses a cooling water tank for a plastic ribbon drawing machine, which mainly consists of the plastic ribbon drawing machine and the cooling water tank. In use, the plastic ribbons are produced by the plastic ribbon drawing machine and then fed into the cooling water tank for cooling. However, this method has the following problem: after the plastic ribbons are cooled in the cooling water tank, some moisture remains on the surface of the ribbons. This moisture affects subsequent processing of the plastic ribbons and is inconvenient to use. Therefore, a plastic extrusion and drawing device with a drying function for plastic ribbons is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a plastic extrusion drawing device for the production of plastic packaging bags that can dry the residual moisture on the plastic ribbon after cooling, facilitating subsequent processing of the plastic ribbon, and is convenient to use, practical and reliable.

[0004] This utility model discloses a plastic extrusion and drawing device for producing plastic packaging bags, comprising a base plate, an extruder, and a mold. The extruder is fixedly mounted on the base plate, and the mold is located at the output end of the extruder. Both the extruder and the mold are fixedly mounted on the upper part of the base plate. It also includes a water-cooling mechanism, a drying mechanism, and a winding mechanism. The water-cooling mechanism is mounted on the base plate and has a cooling function. The drying mechanism is mounted on the base plate and has a drying function. The winding mechanism is mounted on the base plate and has a winding function. In producing plastic woven bags, plastic ribbons are first produced. Plastic raw materials are added to the extruder, which heats and melts the raw materials before extruding them into the mold, thus forming plastic ribbons. The plastic ribbons are then cooled by the water-cooling mechanism, dried by the drying mechanism, and finally wound up by the winding mechanism. This device dries any residual moisture on the plastic ribbons after cooling, facilitating subsequent processing. It is convenient to use and has high practicality and reliability.

[0005] Preferably, the water-cooling mechanism includes a water-cooling box, rollers, two sets of support plates, and two sets of guide rollers. The water-cooling box is fixedly installed on the upper part of the base plate and has a chamber inside. The upper end of the water-cooling box is open. The rollers are rotatably installed on the lower part of the water-cooling box. Both sets of support plates are fixedly installed on the base plate and are located on the left and right sides of the water-cooling box, respectively. The two sets of guide rollers are rotatably installed on the two sets of support plates. After the plastic ribbon is extruded and formed in the mold, the plastic ribbon passes through the guide rollers, rollers, and another set of guide rollers in sequence. When the plastic ribbon passes through the rollers, it comes into contact with the water in the chamber of the water-cooling box. The water cools the plastic ribbon in the chamber of the water-cooling box, thus facilitating the cooling of the plastic ribbon.

[0006] Preferably, the winding mechanism includes a support plate, a servo motor, and a winding roller. The support plate is fixedly mounted on the upper end of the base plate, the servo motor is fixedly mounted on the support plate, and the winding roller is rotatably mounted on the support plate. The input end of the winding roller is connected to the servo motor. The right end of the plastic ribbon is wound around the winding roller, the servo motor is turned on, and the servo motor drives the winding roller to rotate. The rotating winding roller winds up the plastic ribbon, thereby collecting the dried plastic ribbon on the winding roller, which facilitates the winding of the plastic ribbon.

[0007] Preferably, the drying mechanism includes two sets of fixed plates, two sets of rotating shafts, two sets of absorbent sponges, and a negative pressure water absorption mechanism. Both sets of fixed plates are fixedly mounted on the base plate, and the two sets of rotating shafts are rotatably mounted on the two sets of fixed plates. Each set of rotating shafts has a cavity, and the side walls of each set of rotating shafts are provided with multiple sets of permeable holes communicating with the cavities. The two sets of absorbent sponges are fixedly fitted onto the two sets of rotating shafts. The negative pressure water absorption mechanism is connected to the two sets of rotating shafts and provides a negative pressure function. After the plastic ribbon is cooled in the water-cooling box, it passes through the two sets of absorbent sponges in sequence. As the plastic ribbon passes through the two sets of absorbent sponges, the two sets of absorbent sponges wipe the moisture off the surface of the plastic ribbon. Simultaneously, the negative pressure mechanism is activated, creating negative pressure within the two sets of rotating shafts. This negative pressure causes the moisture in the absorbent sponges to enter the two sets of rotating shafts, and then the moisture is collected in the negative pressure water absorption mechanism via the two sets of rotating shafts. This facilitates the drying of the plastic ribbon surface.

[0008] Preferably, the negative pressure water absorption mechanism includes two sets of rotary joints, two sets of conveying pipes, a discharge pipe, a water collection tank, and a vacuum pump. The two sets of rotary joints are respectively fixedly mounted on two sets of fixed plates. The front parts of the two sets of rotating shafts are connected to the two sets of rotary joints respectively. The front ends of the two sets of rotating shafts are open. The upper ends of the two sets of conveying pipes are connected to the two sets of rotary joints respectively. The lower ends of the two sets of conveying pipes are connected to the discharge pipe. The output end of the discharge pipe is connected to the water collection tank. A vacuum pump is installed on the water collection tank. The input end of the vacuum pump is located in the water collection tank and above the liquid level in the water collection tank. When the vacuum pump is turned on, the water collection tank is in a negative pressure state. Then, through the discharge pipe, the two sets of conveying pipes, and the two sets of rotary joints, the two sets of rotating shafts are in a negative pressure state. This allows the water in the two sets of absorbent sponges to enter the two sets of rotating shafts through the water-permeable holes on the two sets of rotating shafts. Then, the water in the two sets of rotating shafts enters the water collection tank in sequence through the two sets of conveying pipes and the discharge pipe, which facilitates the drying of the two sets of absorbent sponges.

[0009] Preferably, the water collection tank is equipped with a level gauge; this facilitates the monitoring of the liquid level in the water collection tank.

[0010] Preferably, both sets of rotating shafts are made of stainless steel; this setting delays rusting of the two sets of rotating shafts and improves their service life.

[0011] Compared with the prior art, the beneficial effects of this utility model are: after cooling the plastic ribbon, the residual moisture on the plastic ribbon can be dried, which facilitates the subsequent processing of the plastic ribbon, making it convenient to use and highly practical and reliable.
