Description

Technical Field

[0001] This utility model relates to the field of fiberglass storage tank production technology, specifically to a fiberglass storage tank winding molding device. Background Technology

[0002] The main materials of FRP (fiberglass reinforced plastic) storage tanks include glass fiber and resin. Glass fiber is a high-strength, high-modulus inorganic non-metallic material with characteristics such as light weight, high strength, high temperature resistance, and corrosion resistance. Resin is an organic polymer compound with excellent adhesion, chemical corrosion resistance, and processing performance. Glass fiber and resin are combined together through specific processes to form the material of FRP storage tanks.

[0003] The fiberglass storage tank winding molding device is a highly efficient, flexible, and advanced production equipment. Through a specific winding process, resin-impregnated glass fibers are wound onto a mandrel according to a certain pattern. After curing, demolding, and other steps, fiberglass storage tank products are finally obtained, providing a strong guarantee for the manufacturing of fiberglass storage tanks. It is widely used in chemical, environmental protection, and food industries.

[0004] Existing fiberglass tank winding molding equipment generally has a fixed diameter for the inner support frame of the mandrel, making it impossible to adjust the mandrel diameter by changing the inner support frame to accommodate fiberglass tanks of different diameters. This results in poor applicability of the equipment due to its inability to meet the winding requirements of mandrel installation for fiberglass tanks of different diameters, further reducing its adaptability. In addition, the common method of using hydraulic cylinders to eject the mandrel for detachment is not only difficult to separate the mandrel from the fiberglass tank, but also prone to damage to the fiberglass tank, further reducing the demolding effect of the equipment.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Example 1

[0025] Reference Figure 1-5This is the first embodiment of the present invention, which provides a fiberglass storage tank winding molding device, including a support base 1, two symmetrical inner support frames 2 rotatably mounted on the support base 1, a transverse sliding screw 16 and a longitudinal sliding screw 17 are provided at the upper end of the support base 1 near the inner support frame 2, a fiberglass roller 19, an adhesive placement box 18 and a pressure roller 20 are provided above the longitudinal sliding screw 17, a storage tank core mold 3 is movably mounted on the outer side wall of the two inner support frames 2, a rotating shaft 4 is installed through the center of the inner support frame 2, a circular fixing block 5 and a central locking block 6 are intermittently provided on the outer side wall of one side of the inner support frame 2 near the rotating shaft 4, a plurality of rotating gears 7 are rotatably mounted at equal intervals between the circular fixing block 5 and the central locking block 6, and a non-circular tooth block 8 and a circular tooth block 9 are respectively meshed on the outer side wall of the plurality of rotating gears 7, and an inner support block 10 is fixedly installed at the end port of one side of the inner support frame 2 near the non-circular tooth block 8.

[0026] A support rod is fixedly installed on the upper end of the support base 1. An inner support frame 2 is rotatably installed between the two support rods. Several irregular grooves are evenly spaced on the inner sides of the circular fixing block 5 and the central fixing block 6. Several irregular tooth blocks 8 are slidably installed on the inner sides of the irregular grooves. A circular fixing block 5 is fixedly installed on the outer wall of one side of the inner support frame 2 near the center of the rotating shaft 4. A central fixing block 6 is fixedly installed on one side of the inner support frame 2 near the outer wall of the circular fixing block 5.

[0027] Several irregularly shaped toothed blocks 8 are slidably installed on the inner sides of both the circular fixed block 5 and the central block 6. A circular toothed block 9 is rotatably installed on the inner side of the central block 6 near the lower end. Irregularly shaped toothed blocks 8 and circular toothed blocks 9 are respectively meshed on the outer side wall of the rotating gear 7. A rotary motor is fixedly installed at the center of one side of the inner support frame 2. The output end of the rotary motor is connected to the rotating shaft 4. A bidirectional motor is fixedly installed on one side of the inner support frame 2 near the upper end of the rotary motor. The output end of the bidirectional motor is connected to the rotating gear 7.

[0028] When the fiberglass storage tank winding molding device is in use, the operator first places a stack of fiberglass cloth on the fiberglass roller 19, fills the glue placement box 18 with glue, so that the glue application roller shaft in the glue placement box 18 can rotate to evenly coat the passing fiberglass thread with glue, and starts the transverse motor set on one side of the transverse sliding screw 16 to drive the transverse sliding screw 16 to rotate, thereby driving the transverse support plate to move left and right under the rotation of the transverse sliding screw 16. Then, starts the longitudinal motor set on one end of the longitudinal sliding screw 17 to drive the longitudinal sliding screw 17 to rotate, thereby driving the longitudinal support plate to move back and forth under the rotation of the longitudinal sliding screw 17. Then, starts the rotary motor, so that the rotary motor drives the rotary shaft 4 to rotate, thereby pressing the fiberglass cloth of the fiberglass roller 19 onto the outer wall of the storage tank core mold 3 through the pressure roller 20 for winding molding;

[0029] During the installation of the tank core mold 3, a bidirectional motor is first started, which drives the rotating gear 7 to rotate. This, in turn, drives the irregular toothed block 8 and the circular toothed block 9 to rotate. Under the drive of multiple sets of rotating gears 7, multiple sets of inner support blocks 10 fixed at one end of the irregular toothed block 8 are pushed outward to achieve the required diameter of the core mold. This allows the diameter of the core mold to be changed by adjusting the inner support blocks 10 to accommodate fiberglass tanks of different diameters. This avoids the poor applicability of the device due to its inability to meet the winding requirements of core mold installation for fiberglass tanks of different diameters, and further improves the adaptability of the device.

[0030] Example 2

[0031] Reference Figure 1-5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: both ends of the inner center of the inner support block 10 are provided with cross-shaped sliding grooves, and irregular adjustment blocks 11 are slidably installed inside the two cross-shaped sliding grooves. Adjustment blocks 12 are fixedly installed on the outer wall of one end of the irregular adjustment blocks 11. A convex anchor block 13 is fixedly installed at the center of the port of one end of the inner support block 10 near the adjustment block 12. A plug-in block 14 is fixedly installed on the outer wall of the other end of the inner support block 10 near the irregular adjustment block 11. A plug-in recess 15 is provided at the center of the inner side of the plug-in block 14 to facilitate the plug-in installation of the convex anchor block 13. Threaded holes for easy penetration and anchoring of the irregular adjustment blocks 11 are provided at equal intervals at the upper ends of both ends of the inner support block 10.

[0032] After the fiberglass storage tank is wound and cured, the screws at the upper ends of the inner support block 10 are loosened first. Then, the irregular adjustment block 11 is slid to allow the convex anchor block 13 to be easily pulled out from the insertion recess 15. Then, the bidirectional motor is started, and the rotating gear 7 rotates counterclockwise under the drive of the bidirectional motor, thereby driving multiple sets of irregular tooth blocks 8 to slide inward, so that multiple sets of inner support blocks 10 also slide inward further. At the same time, the bottom of the formed fiberglass storage tank is supported, so that the inside of the formed fiberglass storage tank appears to be unsupported. Then, the inner support frames 2 on both sides are moved, so that the core mold can be easily removed without inner support, achieving rapid demolding. This avoids the situation where the fiberglass storage tank is damaged due to the method of using a hydraulic cylinder to eject the core mold, and further improves the demolding effect of the device.

[0033] The remaining structure is the same as that in Example 1.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
