Description

Technical Field

[0001] The utility model relates to the field of production of nylon modified thermal insulation strips, in particular to a synchronous extruder for producing nylon modified thermal insulation strips. Background Art

[0002] Nylon-modified thermal insulation strips are a type of thermal insulation material used in aluminum profiles for thermally insulated doors and windows. They are typically based on nylon, with various modifiers added to improve its physical properties, such as strength, heat resistance, and aging resistance. The modified nylon material exhibits excellent weather and UV resistance, allowing it to withstand prolonged outdoor use without aging. Nylon-modified thermal insulation strips are typically produced by extrusion molding. The strips are formed by adding the appropriate modifiers to a nylon base material and then passing through an extruder. After cooling and curing, they are finally formed into the desired insulation strip shape.

[0003] Although ordinary extruders can achieve simultaneous heating and extrusion of raw materials, the amount of raw materials fed into the extruder may be unstable, requiring frequent manual intervention to adjust the raw material supply, affecting production efficiency. In addition, due to the unstable supply of raw materials, it may be necessary to frequently adjust the working state of the extruder, resulting in increased energy consumption, while also increasing uncertainty and scrap rate in the production process, ultimately affecting overall production costs and product quality.

[0004] Therefore, a synchronous extruder for producing nylon modified thermal insulation strips is particularly needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: A synchronous extruder for producing nylon modified thermal insulation strips, see Figure 1-Figure 5As shown, it includes a shell 1, a support frame 2, a controller 3, an insulation sleeve 4, a heating wire 5, a mold 6, a discharge assembly, a discharge port 17, a placement plate 18, an electric push rod 19 and a clamping plate 20. The shell 1 is connected between the inner upper parts of the two support frames 2 by bolts, the heating wire 5 is connected to the outside of the shell 1 by bolts, the controller 3 is connected to the front side of the heating wire 5 by bolts, and is electrically connected to the heating wire 5. The insulation sleeve 4 is arranged on the outside of the shell 1 and covers the heating wire 5 to prevent the heating wire 5 from being exposed to the outside, and the controller 3 passes through the insulation sleeve 4. The left and right sides of the insulation sleeve 4 are both close to the outer wall of the shell 1, so that the heat generated by the heating wire 5 is effectively isolated by the insulation sleeve 4. The discharge assembly is arranged inside the shell 1, and the discharge port 17 is connected to the right side of the top of the shell 1 by welding. The upper part of the discharge port 17 is a flat-topped cone design, which can ensure that the raw materials flow smoothly into the discharge port 17, prevent the accumulation of raw materials, and improve the discharge efficiency. The placement plate 18 is connected to the lower left part of the shell 1 by welding, and the two electric push rods 19 are distributed front and back, and are connected to the front and back sides of the lower left part of the shell 1 by bolts. The splint 20 is connected to the telescopic rod of the electric push rod 19 by welding. The mold 6 is placed on the placement plate 18 and is located to the right of the two splints 20, so that the splint 20 cooperates with the shell 1 to clamp the mold 6, and a rubber pad is provided on the contact surface between the placement plate 18 and the mold 6, which can increase the friction between the mold 6 and ensure that the mold 6 is firmly placed. It also includes a material control mechanism, which is arranged between the shell 1, the discharge assembly and the discharge port 17.

[0024] See Figure 3-Figure 4 As shown, the discharging assembly includes a motor 7, a spiral plate 701, a connecting plate 8 and a gear 9. The connecting plate 8 is connected to the rear side of the right part of the shell 1 by welding, and the motor 7 is connected to the connecting plate 8 by bolts. The two spiral plates 701 are distributed front and back and are rotatably connected to the front and back sides of the shell 1. The gear 9 is connected to the right side of the spiral plate 701 by welding, and the rear gear 9 is fixedly connected to the output shaft of the motor 7, and the two gears 9 are engaged with each other.

[0025] See Figure 4As shown, the material control mechanism includes a clamping column 10, a sliding sleeve 11, a limiting sleeve 12, a top block 13, a rotating block 14, a torsion spring 15 and a flip plate 16. The limiting sleeve 12 is connected to the front side of the right part of the shell 1 by welding, the clamping column 10 is connected to the front gear 9 by welding, the sliding sleeve 11 is slidably connected to the inside of the limiting sleeve 12 and is slidably connected to the clamping column 10, the top block 13 is connected to the upper end of the sliding sleeve 11 by welding, the flip plate 16 is rotatably connected to the middle part of the discharge port 17, and the contact surface of the flip plate 16 and the discharge port 17 is provided with silicone. The pad has a small damping when the silicone pad slides, which can effectively prevent the flip plate 16 from scraping the inner wall of the discharge port 17 without hindering the rotation of the flip plate 16. The rotating block 14 is connected to the right side of the flip plate 16 through the discharge port 17 by welding, and is located above the top block 13. The left edge of the rotating block 14 is staggered from the rightmost edge of the discharge port 17 to ensure that the rotating block 14 will not interfere with the discharge port 17 when it rotates clockwise at any angle. The torsion spring 15 is sleeved on the right side of the flip plate 16, and its two ends are fixedly connected to the discharge port 17 and the flip plate 16 respectively.

[0026] First, the operator starts the electric push rod 19, controls its telescopic rod to extend, drives the splint 20 to move to the left to loosen the mold 6, then removes the original mold 6, replaces the mold 6 of the appropriate type, controls the telescopic rod of the electric push rod 19 to retract, drives the splint 20 to move to the right to clamp the mold 6, completes the replacement of the mold 6, closes the electric push rod 19, and then pours the raw material into the discharge port 17, so that the raw material stagnates on the flip plate 16, and then controls the heating temperature of the heating wire 5 through the controller 3, so that the heating wire 5 preheats the inside of the shell 1, and then starts the motor 7, so that its output shaft drives the rear gear 9 to rotate counterclockwise. At this time, the rear gear 9 is engaged with the front gear 9, so that the front gear 9 drives the clamping column 10 to rotate counterclockwise, and the clamping column 10 slides along the sliding sleeve 11 and pushes the sliding sleeve 11 to move upward, and the sliding sleeve 11 drives the top block 13 to move upward for extrusion. The rotating block 14 drives the flip plate 16 to rotate clockwise, opens the discharge port 17 for discharge, and the torsion spring 15 is deformed accordingly. When the raw material is discharged into the shell 1, the clamping column 10 continues to slide along the sliding sleeve 11 and pulls the sliding sleeve 11 to move downward. The sliding sleeve 11 drives the top block 13 to move downward and no longer squeezes the rotating block 14. The torsion spring 15 then returns to its original shape, prompting the flip plate 16 to drive the rotating block 14 to rotate counterclockwise and reset, stopping discharge. In this reciprocating manner, the sliding sleeve 11 continues to drive the top block 13 to move up and down, so that the top block 13 intermittently squeezes the rotating plate for discharge. The raw material discharged into the shell 1 contacts the spiral plate 701, and the gear 9 drives the spiral plate 701 to rotate, transporting the raw material to the left, so that after the raw material is heated, it is extruded into strips through the mold 6. When the raw material is fully heated and extruded, the motor 7 and the heating wire 5 are turned off.

Personnel familiar with the art may make various modifications or changes to the above embodiments without departing from the utility model concept of the present invention. Therefore, the scope of protection of the present invention is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
