Description

Technical Field

[0001] The invention belongs to the technical field of PA66 nylon thermal insulation strip production, and specifically relates to PA66 nylon thermal insulation strip production equipment. Background Art

[0002] PA66 is a high-performance engineering plastic with excellent mechanical strength, stiffness and heat resistance. It can maintain good performance in high temperature environments. PA66 nylon insulation strips are commonly used in various industries and applications, especially in environments that require high strength, heat resistance and chemical corrosion resistance.

[0003] In the prior art, the PA66 nylon insulation strip production equipment usually uses wind or water to cool and solidify the product at the extrusion port during use. However, the heat dissipation effect is effective under the action of wind, but when flushing with water, the impact force of the water flow acts on the surface of the just-extruded product, causing the product to have a certain degree of impact deformation. Although it has a good cooling effect, it affects the molding quality of the strip PA66. At the same time, since the extruded strip PA66 is cooled and solidified at the outer end, it has a tendency to bend downward under the influence of gravity, and a bending phenomenon occurs at the extrusion end, resulting in poor overall straightness of the molded strip PA66 and a certain bending curvature, thereby greatly reducing the production quality and poor use effect.

[0004] In addition, the PA66 nylon insulation strip production equipment in the prior art needs to cut off the longer part and transfer it to the subsequent fixed-length processing platform for target length fixed-length cutting after completing the extrusion and curing of the PA66 strips. The actual intermediate transportation is time-consuming and labor-intensive, the fixed-length cutting requires special processing, the process steps are cumbersome, the cutting is direct cutting in a single direction, the cutting stress is concentrated on the cutting front, there is pressure deformation during cutting, the overall production efficiency is low, and the quality of the cutting end face is poor.

[0041] The cooling assembly 5 includes an arc frame 51, a distribution ring 52, a connecting rod 53 and a spray port 54. The arc frame 51 is evenly spaced around the arc frame. The distribution ring 52 is fixedly sleeved on the outer surface of the arc frame 51 and is connected to the arc frame 51. The distribution ring 52 is connected to the rotating distribution assembly 3 through the connecting rod 53. The spray port 54 is opened at the end of the arc frame 51.

[0042] The right end of the mold head 1 is provided with an annular cavity 9 which is connected with the liquid inlet 4 . The inner surface of the annular cavity 9 is rotatably connected with the rotating distribution component 3 . An annular groove is provided inside the mold head 1 .

[0043] The rotating distribution assembly 3 includes a rotating ring 31, a No. 1 distribution chamber 32, a No. 2 distribution chamber 33 and a middle hole 34. The rotating ring 31 is rotatably sleeved inside the ring chamber 9. A through hole is provided on the outer surface of the rotating ring 31. A retaining ring is fixedly sleeved on the inner surface of the rotating ring 31. The retaining ring is rotatably sleeved in the annular groove. The No. 1 distribution chamber 32 is provided at the inner end of the rotating ring 31 and is connected to the liquid inlet 4. The No. 2 distribution chamber 33 is provided inside the rotating ring 31 and is connected to the connecting rod 53 in the cooling assembly 5. The two ends of the middle hole 34 are respectively connected to the No. 1 distribution chamber 32 and the No. 2 distribution chamber 33.

[0044] By rotating the ring 31 and the annular cavity 9, the retaining ring and the annular groove cooperate to maintain a stable rotating connection. The No. 1 distribution cavity 32, the middle hole 34 and the No. 2 distribution cavity 33 form a flow channel for cooling water, ensuring that the water flow is input into the cooling component 5 in a rotating state to achieve cooling treatment.

[0045] Embodiment 1: When in use, as the molten material is squeezed into the interior of the die head 1 in the extrusion portion 2 and gradually squeezed out from the outlet at the right end of the die head 1, the power unit 8 is kept to drive the rotation of the gear 10, so that the rotating distribution component 3 rotates, and the cooling water is input into the liquid inlet 4. As the rotating ring 31 rotates, the cooling water enters the ring cavity 9 through the liquid inlet 4 and passes into the middle hole 34 along the No. 2 distribution cavity 33, so that the cooling liquid is quickly input into the No. 1 distribution cavity 32, and the cooling liquid located in the No. 1 distribution cavity 32 is input into the interior through the connecting rod 53 of the cooling component 5, and The cooling liquid is distributed and inputted into each group of arc frames 51.

Meanwhile, the cooling liquid after heat exchange is further ejected through the ejection port 54. The cooling liquid ejected from the arc end surface of the arc frame 51 is ejected toward an arc end of the adjacent arc frame 51 and dispersed after collision. The rotating distribution component 3 drives the cooling component 5 to rotate, so that the arc frame 51 supports and rotates on the outside of the molded product to eject cooling water, and the cooling water is ejected, collides and splashes on the outside of the molded product to complete indirect and indirect cooling.

[0046] Firstly, by utilizing a plurality of groups of arc frames 51 distributed in a surrounding manner and cooperating with the cooling water introduced inside, the outer side of the molded product is surrounded and supported by retaining a spacing. On the one hand, the cooling water in the arc frame 51 is used to indirectly cool the product. On the other hand, the cooling water is sprayed out in a tangential direction of the product at the strip molding position along the spacing between the arc frames 51 in conjunction with the spray port 54 arranged on the arc end face. The splashing water flow after the collision directly contacts the molded product to complete rapid cooling, thereby effectively avoiding the impact pressure generated by the direct spray cooling water flow on the surface of the molded product. In conjunction with the large amount of cooling water splashed and wrapped around the outer side of the molded product, the molded product is cooled in a comprehensive, safe and efficient manner by direct and indirect coordination after weakening the impact energy, thereby improving the speed of extrusion cooling and solidification of the molded product. The rapidly rotating arc frame 51 surrounds the outer side of the molded product to dynamically support the extruded product, thereby avoiding bending and deformation due to gravity during extrusion, further improving the quality during extrusion cooling molding, ensuring that the extruded strip PA66 maintains flatness, and comprehensively improving the molding quality.

[0047] Among them, a cutting component 6 is provided on the end face of the rotating distribution component 3, and the cutting component 6 rotates to complete the cutting. The cutting component 6 includes: a cutting blade plate 61, an electric push rod 62 and a connecting plate 63. The cutting blade plate 61 is located at the left front of the right end of the cooling component 5 and is close to the arc frame 51. The area of ​​the cutting blade plate 61 is larger than the cross-sectional area of ​​the forming hole of the mold head 1. The fixed end of the electric push rod 62 is installed and fixed on the end face of the rotating ring 31. One end of the connecting plate 63 is fixed on the front side of the cutting blade plate 61, and the other end of the connecting plate 63 is fixedly connected to the movable end of the electric push rod 62. An air passage is provided inside the connecting plate 63.

[0048] When the cutting assembly 6 rotates, it adheres to the outer end surface of the arc frame 51 to complete the complete cutting process of the formed product, and the surrounding cutting quality is better. The electric push rod 62 provides a driving force to achieve reciprocating movement.

[0049] Among them, a purge assembly 7 is provided on one side of the cutting assembly 6, and the purge assembly 7 includes an air pump 71, an air pipe 72, a through hole 73 and an intermediate cavity 74. The air pump 71 is fixed to the side of the rotating distribution assembly 3 through a mounting bracket, and the air pipe 72 is a flexible pipeline. The air inlet end of the air pipe 72 is fixedly connected to the air outlet of the air pump 71, and the air pipe 72 movably passes through the rotating distribution assembly 3. The other end of the air pipe 72 is fixedly connected to the connecting plate 63 and is connected to the airway inside the connecting plate 63. The intermediate cavity 74 is opened inside the cutting blade plate 61, and the through holes 73 are respectively on the back side of the cutting blade plate 61 and are connected to the intermediate cavity 74. The intermediate cavity 74 is connected to the airway in the connecting plate 63.

[0050] The purge assembly 7 cooperates with the displacement of the cutting assembly 6 to blow air when it moves to a position aligned with the die head 1, thereby achieving internal purging and cleaning to prevent residual impurities from contaminating the molded product during extrusion molding.

[0051] Among them, a power unit 8 is fixedly provided on the top of the die head 1, and the power unit 8 includes a motor and a gear 2. The output shaft of the motor is fixedly sleeved with the gear 2 and drives the gear 2 to rotate. The outer surface of the rotating ring 31 is fixedly sleeved with a gear 10, and the gear 10 is meshed with the gear 2. The extrusion unit 2 is fixed at the left end of the die head 1. The extrusion unit 2 extrude the molten material into the die head 1. The liquid inlet end of the extrusion unit 2 can be provided with a heating mechanism to further supplement heat, provide fluidity of the molten material input, and achieve heat preservation during the input process.

[0052] Embodiment 2: After the rapid cooling and forming of the product is completed, as the solidified product continues to be output forward, the gap start time is set, and as the rotating distribution component 3 drives the cutting component 6 to rotate, the electric push rod 62 drives the connecting plate 63 to move, and the cutting blade 61 quickly approaches the extruded cooled and formed strip product, and as the cutting blade 61 rotates and approaches, the complete rotation cutting is performed; before the production is completed, the electric push rod 62 is started to drive the cutting blade 61 to move and cover the surrounding arc frames 51, so that the through hole 73 in the purge component 7 faces the forming hole of the mold head 1, and the air pump 71 is started, so that the air pump 71 sprays the gas along the middle cavity 74 and the through hole 73 through the air pipe 72, and blows toward the internal forming hole of the mold head 1 to blow out the internal dust and impurities, and then perform subsequent extrusion molding.

[0053] First, by reusing the rotating distribution component 3, the rotating effect is coordinated with the rotating effect to drive the installed cutting component 6 to rotate synchronously while rotating and cooling, and the support and positioning of the cooling component 5 are coordinated, so that the cutting component 6 rotates to perform circumferential cutting toward the extruded and cooled strip PA66 product when it is set to act at the interval time, thereby reducing the investment in additional circumferential power equipment and simultaneously completing rapid equidistant cutting during extrusion molding, further shortening the production process, improving production efficiency, and reducing production costs. At the same time, the rotating circumferential cutting method is used to quickly circumferentially cut along the outer surface of the strip PA66, thereby improving the cutting quality and avoiding deformation of the cutting end face caused by extrusion cutting. By improving the uniform distribution of the cutting force, the actual cutting quality is improved, and the comprehensive effects of high production efficiency and high quality of the molding end face are achieved.

[0054] In addition, by reusing the moving cutting function of the cutting assembly 6 in conjunction with the moving function of the cutting blade 61, before actual extrusion production, by moving the position of the cutting blade 61 and making the through hole 73 opened on the back thereof face the forming hole of the die head 1, in conjunction with the assembled air supply and purge assembly 7, the air flow can be conveniently blown into the forming hole of the die head 1, and the internal cleaning can be completed quickly and completely. The actual operation is simple, and there is no need for special handling and purge equipment for calibration and purge. The operation is simple and quick, which optimizes the production process steps and improves the overall production efficiency.

[0055] The working principle and use process of the present invention are as follows: when in use, as the molten material is squeezed into the interior of the die head 1 in the extrusion part 2 and gradually squeezed out from the outlet at the right end of the die head 1, the power part 8 is kept to drive the rotation of the gear 10, so that the rotating distribution component 3 rotates, and the cooling water is input into the liquid inlet 4. As the rotating ring 31 rotates, the cooling water enters the ring cavity 9 through the liquid inlet 4 and passes into the middle hole 34 along the No. 2 distribution cavity 33, so that the coolant is quickly input into the No. 1 distribution cavity 32, and the coolant located in the No. 1 distribution cavity 32 is input into the interior through the connecting rod 53 of the cooling component 5, and is distributed and input into each group of arc frames 51. The coolant located in the arc frame 51 directly contacts the molded product through the inner wall of the arc frame 51 for heat exchange, thereby realizing cooling treatment. At the same time, the coolant after heat exchange is further ejected through the ejection port 54, and the coolant ejected from the arc end face of the arc frame 51 is ejected toward an arc end of the adjacent arc frame 51, and dispersed after collision, so as to maintain the rotating distribution. Component 3 drives the cooling component 5 to rotate, so that the arc frame 51 supports and rotates on the outside of the molded product to spray cooling water, and the cooling water is sprayed, collided and splashed on the outside of the molded product to complete indirect and indirect cooling; after the product is quickly cooled and molded, as the solidified product continues to be output forward, the gap start time is set, and as the rotating distribution component 3 drives the cutting component 6 to rotate, the electric push rod 62 drives the connecting plate 63 to move, and the cutting blade 61 quickly approaches the extruded cooled and molded strip product, and as the cutting blade 61 rotates and approaches, the complete rotation cutting is performed; before the production is completed, the electric push rod 62 is started to drive the cutting blade 61 to move and cover the arc frames 51 surrounding each other, so that the through hole 73 in the purge component 7 faces the molding hole of the die head 1, and the air pump 71 is started, so that the air pump 71 sprays the gas along the middle cavity 74 and the through hole 73 through the air pipe 72, and blows toward the molding hole inside the die head 1 to blow out the internal dust and impurities, and then perform subsequent extrusion molding.
