Description

Technical Field

[0001] This utility model relates to the field of galvanized composite material technology, specifically to a spiral pultrusion molding device for galvanized composite materials. Background Technology

[0002] In modern industry, galvanized composite materials are widely used in construction, transportation, energy, and many other sectors due to their excellent corrosion resistance, high strength, and good processing characteristics. Spiral pultrusion, as one of the important methods for producing galvanized composite materials, involves continuously heating and curing resin-impregnated reinforcing materials in a mold. This process offers advantages such as high production efficiency and stable dimensional accuracy, meeting the needs of large-scale industrial production.

[0003] From the perspective of screw structure design, while the application of single-screw screws is simple in structure and low in cost, it has inherent defects. During material conveying, a single-screw screw causes an uneven flow velocity distribution within the barrel, with material flowing faster near the screw surface and slower near the barrel wall. This velocity difference leads to uneven stress distribution during material flow, making it difficult to maintain a stable cross-sectional shape during molding. This uneven material flow problem caused by single-screw screws is particularly pronounced when producing composite profiles with complex cross-sectional contours, easily causing dimensional deviations, reducing product yield, increasing production costs, and failing to meet the modern industrial demand for high-precision composite material products.

[0026] This utility model provides the following technical solution:

[0027] Example 1

[0028] Please see Figure 1-3 This utility model provides a technical solution: a spiral pultrusion molding device for galvanized composite materials, including a base 1, with support seats 2 symmetrically fixedly connected to the top of the base 1, a spiral pultrusion mechanism 3 on the top of the two support seats 2, and a disintegration mechanism 4 inside the spiral pultrusion mechanism 3.

[0029] The spiral pultrusion mechanism 3 includes a fixed base 31, which is fixedly connected to the top of two support bases 2. A material conveying trough 32 is provided inside the fixed base 31. A feed cylinder 33 is fixedly connected to the top of the fixed base 31 near the right side. A discharge pipe 34 is fixedly connected to the left side of the fixed base 31. A first spiral rod 35 is rotatably connected to the left side of the inner wall of the material conveying trough 32 near the front.

A first L-shaped seat 39 is fixedly connected to the right side of the fixed base 31 near the front. A first motor 311 is fixedly connected to the right side of the first L-shaped seat 39. A fixed cover is fixedly connected to the right side of the fixed base 31. A first heat dissipation hole 313 is provided on the right side of the fixed base 31.

[0030] The right side of the fixed base 31 has holes on the front and rear sides that match the first spiral rod 35 and the second spiral rod 36. The surfaces of the first spiral rod 35 and the second spiral rod 36 pass through and are rotatably connected in the holes. The first spiral rod 35 and the second spiral rod 36 are symmetrical in front and back.

[0031] The first gear 37 meshes with the second gear 38, and the output end of the first motor 311 is fixedly connected to the right end of the first screw rod 35.

[0032] Example 2

[0033] Please see Figure 4-6 Furthermore, based on Example 1, a disintegration mechanism 4 was obtained.

[0034] The dispersing mechanism 4 includes a second fixed cover 41, which is fixedly connected to the front of the discharge cylinder. A second heat dissipation hole 42 is provided on the front of the first fixed cover 312. A first dispersing roller 45 is rotatably connected to the back of the inner wall of the feed cylinder 33 near the left side. A second dispersing roller 46 is rotatably connected to the back of the inner wall of the feed cylinder 33 near the right side. A third gear 47 is fixedly connected to the surface of the first dispersing roller 45 near the front end. A fourth gear 48 is fixedly connected to the surface of the second dispersing roller 46 near the front end. A third dispersing roller 49 is rotatably connected to the back of the inner wall of the feed cylinder 33 near the bottom. A second L-shaped seat 43 is fixedly connected to the front of the feed cylinder 33 near the left side. A second motor 44 is fixedly connected to the front of the second L-shaped seat 43. A first pulley 411 is fixedly connected to the surface of the output shaft of the second motor 44. A second pulley 412 is fixedly connected to the surface of the third dispersing roller 49 near the front end. A belt 413 is sleeved between the first pulley 411 and the second pulley 412.

[0035] The feed cylinder 33 has holes on the left and right sides of its front side that match the first dispersing roller 45 and the second dispersing roller 46. The surfaces of the first dispersing roller 45 and the second dispersing roller 46 pass through and are rotatably connected in the corresponding holes.

[0036] The first dispersing roller 45 and the second dispersing roller 46 are arranged in a cross pattern. The third gear 47 meshes with the fourth gear 48. The output end of the second motor 44 is fixedly connected to the front end of the first dispersing roller 45.

[0037] The feed cylinder 33 has a hole on its front side near the bottom that matches the second dispersing roller 46, and the surface of the third dispersing roller 49 passes through and is rotatably connected to the hole.

[0038] In actual operation, when this device is used, the galvanized composite material raw material is first fed into the feed cylinder 33. The second motor 44 is started, and its output shaft drives the first pulley 411 to rotate. Through the transmission of the belt 413, the second pulley 412 drives the third dispersing roller 49 to rotate. Simultaneously, the first dispersing roller 45, directly connected to the output end of the second motor 44, also begins to rotate. Since the third gear 47 on the surface of the first dispersing roller 45 meshes with the fourth gear 48 on the surface of the second dispersing roller 46, the rotation of the first dispersing roller 45 drives the second dispersing roller 46 to rotate in the opposite direction. The first dispersing roller 45, the second dispersing roller 46, and the third dispersing roller 49 are arranged in a crisscross pattern. During rotation, they thoroughly disperse the raw material fed into the feed cylinder 33, preventing clumping and ensuring uniform mixing, thus guaranteeing the quality of subsequent molding.

[0039] The pultruded raw material enters the feeding trough 32 within the fixed base 31. The first motor 311 is started, and its output drives the first auger 35 to rotate. Because the first gear 37 on the surface of the first auger 35 meshes with the second gear 38 on the surface of the second auger 36, the rotation of the first auger 35 causes the second auger 36 to rotate in the opposite direction. The first auger 35 and the second auger 36 are symmetrically positioned within the feeding trough 32. Their rotation transports the raw material from the right side of the feed cylinder 33 to the left side of the discharge pipe 34, and during this transport, the raw material is compressed, gradually forming under pressure. Finally, the formed galvanized composite material is output through the discharge pipe 34, completing the entire pultrusion process.
