Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing devices, in particular to an automatic mixing plastic braided wire drawing device. Background Art

[0002] Plastic woven fabrics are widely used in packaging, construction, agriculture, and other fields due to their high strength, corrosion resistance, and low cost. The wire drawing process in the production process is crucial and directly affects the quality and performance of the woven fabric.

[0003] In the existing plastic woven fabric production process, the raw material mixing process is largely manual. Workers rely on experience to mix plastic particles and additives of different types and proportions. This method is not only inefficient, but also difficult to ensure the uniformity and stability of the mixture in each batch. However, this traditional mixing method has exposed many drawbacks in actual production. In terms of mixing efficiency, when the rotating shaft is driven by a motor, the material mainly moves in a circular motion around the rotating shaft due to centrifugal force and friction. Due to the limited axial displacement, the convection and diffusion between materials are weak, and large amounts of materials cannot be fully interwoven and blended. In terms of mixing uniformity, due to the limitations of the rotating shaft structure and motion characteristics, there are obvious mixing blind spots within the mixing chamber. Near the mixing chamber walls and in areas that are difficult for the rotating shaft to reach, materials are prone to localized accumulation, resulting in insufficient contact and dispersion of different types of plastic particles and additives.

[0023] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0024] Reference Figures 1-6 As shown, the utility model provides an automatic mixing plastic weaving and braiding device, comprising: a feeding device 1, for melting plastic particles and extruding the molten plastic; a forming mold 2, which is arranged at the discharge end of the feeding device 1 and forms the molten plastic into a plastic strip; a cooling device 3, which is arranged at the discharge end of the forming mold 2 and is used to quickly cool the hot plastic strip; a filament forming device 4, which is arranged at the discharge end of the cooling device 3 and is used to convey the plastic strip and cut the plastic strip into a filamentous structure; the feeding device 1 comprises an extrusion forming cylinder 11, a mixing cylinder 12 is vertically arranged at the top of the extrusion forming cylinder 11 away from the discharge end, a plurality of dividing cylinders 13 for unloading are arranged on the outside of the mixing cylinder 12, and a mixing component 14 capable of mixing the plastic particles inside the mixing cylinder 12 is also arranged on the outside of the mixing cylinder 12, and the mixing component 14 can suck the plastic particles out from the bottom of the mixing cylinder 12 and enter from the top of the mixing cylinder 12 to mix the plastics evenly. An electrically controlled valve is provided between the mixing barrel 12 and the feeding device 1 to control the plastic particles in the mixing barrel 12 from entering the feeding device 1. The mixing assembly 14 includes a fan 141, which is provided outside the mixing barrel 12 and is capable of flowing air to suck out the plastic particles in the mixing barrel 12 and then transport them into the mixing barrel 12. A first connecting pipe 142 is connected to the air inlet end of the fan 141, one end of which is connected to the bottom of the mixing barrel 12. A second connecting pipe 143 is connected to the discharge end of the fan 141, and one end of the second connecting pipe 143 is connected to the top of the mixing barrel 12.

[0025] First, the plastic particles are pre-stored in the distribution barrel 13 and weighed before entering the mixing barrel 12. At this time, the mixing assembly 14 starts working, the fan 141 is started, and a negative pressure area is formed at the air inlet end of the fan 141. The plastic particles in the mixing barrel 12 are sucked into the fan 141 under the action of atmospheric pressure. The impeller in the fan 141 continues to rotate at high speed to maintain a stable airflow circulation. Under the action of the fan 141, the fan 141 sucks out the plastic particles and air mixture at the bottom of the mixing barrel 12. After passing through the fan 141, the airflow carrying the plastic particles is transported back to the top of the mixing barrel 12 through the second connecting pipe 143, so that the plastic particles re-enter the mixing barrel 12 from the top. The plastic particles spread and roll above the mixing barrel 12, achieving the mixing effect. This cycle repeats and fully mixes the plastic particles. The evenly mixed plastic particles enter the extrusion molding barrel 11, are melted and extruded in the extrusion molding barrel 11, and form molten plastic. The molten plastic then enters the forming die 2, where it is formed into a plastic strip of a predetermined shape and size. The newly formed plastic strip is still hot and enters the cooling unit 3, which rapidly cools it, solidifying it and maintaining the desired shape and size. Finally, the cooled plastic strip enters the filament-forming unit 4, which conveys the strip and cuts it into filaments, completing the entire plastic braided fabric production process.

[0026] The interior of the distributing barrel 13 is divided into a main storage chamber 131 for storing materials and a weighing chamber 132 for weighing. A solenoid valve 133 is provided between the main storage chamber 131 and the weighing chamber 132 to control the drop of materials. A baffle 134 is also rotatably mounted within the weighing chamber 132, and a scale 1341 is mounted on the baffle 134 for weighing the materials. A second rotary drive member 1342 is also fixed to the exterior of the distributing barrel 13 to drive the baffle 134 to rotate.

[0027] The interior of the distributing barrel 13 is mainly divided into two functional areas: the main storage chamber 131 and the weighing chamber 132. The main storage chamber 131 serves as the main storage space for materials. Its function is to temporarily store a large amount of plastic particles, providing sufficient material reserves for the subsequent weighing and unloading processes. Through the main storage chamber 131, more plastic particles can be loaded at one time, reducing the frequent addition of materials and improving production efficiency. The weighing chamber 132 is the key area for the distributing barrel 13 to achieve precise unloading. Inside the weighing chamber 132, a baffle 134 is rotatably arranged, and a weighing device 1341 is installed on the baffle 134. The weighing device 1341 can measure the weight of the plastic particles entering the weighing chamber 132 in real time and accurately, providing data support for the precise control of the unloading amount. This design allows the distributing barrel 13 to accurately control the weight of the plastic particles unloaded each time according to production needs, thereby ensuring the uniformity of the subsequent mixing process and the consistency of product quality. A solenoid valve 133 is located between the main storage chamber 131 and the weighing chamber 132. It plays a key role in controlling the descent of materials. When material is unloaded, the solenoid valve 133 opens, allowing the plastic pellets in the main storage chamber 131 to fall into the weighing chamber 132 under the action of gravity. A weighing scale 1341 monitors the weight of the material entering the weighing chamber 132 in real time. When the preset unloading weight is reached, the solenoid valve 133 closes, halting the material's descent. Precise control of the solenoid valve 133 ensures the quantitative transfer of plastic pellets from the main storage chamber 131 to the weighing chamber 132. When the plastic pellets in the weighing chamber 132 reach the preset weight, the second rotary drive 1342 activates, driving the baffle 134 to rotate, allowing the plastic pellets in the weighing chamber 132 to descend smoothly into the mixing drum 12. After unloading is complete, the second rotary drive 1342 resets the baffle 134, resealing the weighing chamber 132 and allowing the next unloading process to begin.

[0028] A screw conveying rod 111 is also rotatably provided inside the extrusion molding cylinder 11 for extruding the molten plastic particles. A first rotary driving member 112 is provided at one end of the extrusion molding cylinder 11 away from the feeding end, and the output end of the first rotary driving member 112 is connected to the screw conveying rod 111.

[0029] The plastic particles that have been thoroughly mixed and uniformly by the mixing assembly 14 enter the feed end of the extrusion molding barrel 11. The plastic particles are melted, and at this time, the first rotary drive member 112 is activated, driving the spiral conveying rod 111 to start rotating. The spiral conveying rod 111 gradually conveys the melted plastic in a direction away from the feed end to the mold for molding. The filament forming device 4 includes a frame 41 and a guide roller 42. The guide roller 42 is used to guide the molded plastic strip; the filament forming device 4 also includes a filament cutting assembly 43 for cutting the plastic strip into a filamentary structure. The filament cutting assembly 43 includes a rotating shaft 432, which is rotatably arranged on the frame 41; a filament cutting knife 433, which can slide in the rotating shaft 432, and a plurality of filament cutting knives are arranged on the rotating shaft 432; a third knob driving member 431, which is fixed to the side of the frame 41, and the output end of the third knob driving member 431 is connected to the rotating shaft 432, and drives the rotating shaft 432 to rotate. At least two limit strips 4321 are provided on the rotating shaft 432, and a groove matching the limit strip 4321 is also provided on the inner side of the wire cutting knife 433. A limit bolt that can fix the wire cutting knife 433 on the rotating shaft 432 is also provided on the wire cutting knife 433. The wire cutting knife 433 can contact the plastic tape and cut the plastic tape into a wire-like structure. The wire cutting assembly 43 also includes a detachable stopper 434 arranged on the side away from the third knob driving member 431, and the rotating shaft 432 is movably connected to the stopper 434.

[0030] When the device is running, the third knob drive 431 is started, and the power is transmitted to the rotating shaft 432, driving the rotating shaft 432 to rotate. The rotation of the rotating shaft 432 drives the wire-splitting knife 433 on it to rotate synchronously. The wire-splitting knife 433 contacts the plastic tape and uses its sharp blade to cut the plastic tape into a filamentous structure. Furthermore, by removing the stopper 434, the user can also install different numbers of wire-splitting knives 433 as needed to adapt to a wider range of processing scenarios. This adjustable and expandable design concept not only improves the versatility and flexibility of the device, but also provides users with more choices, which helps to reduce production costs and improve production efficiency.

[0031] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
