Description

Technical Field

[0001] This utility model relates to the field of fiberglass pipe production technology, and in particular to a winding molding equipment for fiberglass pipe production. Background Technology

[0002] Fiberglass pipe winding molding equipment is a specialized mechanical equipment that uses glass fiber and its products as reinforcing materials and resin as matrix material. It precisely winds resin-impregnated fiber yarns onto a rotating mold according to predetermined circumferential and helical angles and number of layers, and combines heating or room temperature curing to achieve composite curing of the materials, thereby continuously producing fiberglass pipes with specific diameters, wall thicknesses, and strength grades.

[0003] When the equipment drives the mold to rotate at a constant speed, and the resin-impregnated glass fiber yarn is wound onto the mold surface at a predetermined angle, the positioning disc, as a key component for mold positioning and support, inevitably comes into contact with the uncured resin. The viscous nature of the resin makes it extremely easy for it to adhere to the surface of the positioning disc, forming a layer of glue that is difficult to remove. This contamination not only reduces the precision of the positioning disc, affecting the coaxiality and positioning accuracy of subsequent mold installation, but also increases the mechanical resistance during demolding due to the hardened adhesive layer formed after the resin cures, significantly reducing demolding efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problem that the viscous nature of resin makes it easily adhere to the surface of the positioning disc, forming a layer of glue that is difficult to remove. This contamination not only reduces the precision of the positioning disc, affecting the coaxiality and positioning accuracy of subsequent mold installation, but also increases the mechanical resistance during demolding due to the hardened adhesive layer formed after resin curing, significantly reducing demolding efficiency. Therefore, this invention proposes a winding molding device for fiberglass pipe production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a winding molding equipment for fiberglass pipe production, comprising an installation platform, with mold positioning plates respectively provided at both ends of the installation platform, a drive shaft fixedly connected to the center of one side of the mold positioning plate, a rotating component being driven to the other end of the drive shaft, an installation ring fixedly installed on the other side of the mold positioning plate, an anti-stick ring being movably sleeved on the outer side of the installation ring, a base being movably passed through the other end of the other drive shaft, a slide table fixedly connected to one side of the base, a slide rail slidably connected to one side of the slide table, the slide rail being fixedly installed above the installation platform, an electric push rod provided at one end of the slide table, the drive rod of the electric push rod being fixedly connected to the other side of the slide table, and a mold support component being fixedly installed on the outer side of the other drive shaft.

[0006] Preferably, the mold support assembly includes a mounting plate and several support rods. One end of each support rod is fixedly connected to one side of the mounting plate, the mounting plate is fixedly installed on the outside of another drive shaft, and the other end of each support rod extends movably through the interior of the mold positioning plate. A soft sleeve is movably fitted onto the outside of each support rod.

[0007] Preferably, a retaining ring is fixedly connected to the outer side of the anti-stick ring.

[0008] Preferably, the rotating assembly includes a first pulley, a transmission belt, a second pulley, and a drive assembly. The first pulley is fixedly installed at the other end of a transmission shaft. The two ends of the transmission belt are respectively connected to the outer sides of the first pulley and the second pulley. The drive end of the drive assembly is fixedly connected to the center of the second pulley.

[0009] Preferably, the drive assembly includes a drive motor and a speed changer, with the output end of the drive motor being connected to the input end of the speed changer, and the output end of the speed changer being fixedly connected to the center of the second pulley.

[0010] Preferably, the outer side of the anti-stick ring is coated with an anti-stick coating.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the resin is blocked by the retaining ring and will not adhere to one side of the mold positioning plate. The resin at the mold end will come into contact with the surface of the anti-stick ring. Because the anti-stick coating on the surface of the anti-stick ring has low surface energy characteristics, it can greatly reduce the adhesion between the resin and the ring surface, making the resin adhering during the winding process easy to peel off after curing. This effectively prevents the resin from accumulating and curing at the mold end, and significantly improves the demolding efficiency.

[0013] 2. In this utility model, the mold support assembly has several support rods arranged in a ring array to form a multi-point support structure from the inside of the mold. This ensures that the mold maintains axial stability during positioning and high-speed rotation, preventing tilting or offset. Each support rod has a soft sleeve at its end, which is made of a highly elastic and wear-resistant polymer material. This soft sleeve replaces the rigid support rod and directly contacts the inner wall of the mold, creating a flexible buffer layer that effectively protects the inner surface of the mold from scratches and extends the service life of the mold.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figures 1-4As shown, this utility model provides a winding molding equipment for fiberglass pipe production, including a mounting platform 1. Mold positioning discs 2 are respectively installed at both ends of the mounting platform 1. A drive shaft 3 is fixedly connected to the center of one side of the mold positioning disc 2. A rotating component 4 is driven to the other end of one drive shaft 3. A mounting ring 21 is fixedly installed on the other side of the mold positioning disc 2. An anti-stick ring 22 is movably sleeved on the outer side of the mounting ring 21. The outer side of the anti-stick ring 22 is coated with an anti-stick coating. A base 5 is movably passed through the other end of the other drive shaft 3. A slide table 51 is fixedly connected to one side of the base 5. A slide rail 52 is slidably connected to one side of the slide table 51. The slide rail 52 is fixedly installed above the mounting platform 1. An electric push rod 53 is provided at one end of the slide table 51. The drive rod is fixedly connected to the other side of the slide table 51. A mold support assembly 6 is fixedly installed on the outer side of another drive shaft 3. A retaining ring 221 is fixedly connected to the outer side of the anti-stick ring 22. The rotating assembly 4 includes a first pulley 41, a transmission belt 42, a second pulley 43, and a drive assembly 44. The first pulley 41 is fixedly installed at the other end of a drive shaft 3. The two ends of the transmission belt 42 are respectively connected to the outer sides of the first pulley 41 and the second pulley 43. The drive end of the drive assembly 44 is fixedly connected to the center of the second pulley 43. The drive assembly 44 includes a drive motor 441 and a speed changer 442. The output end of the drive motor 441 is connected to the input end of the speed changer 442. The output end of the speed changer 442 is fixedly connected to the center of the second pulley 43.

[0022] The specific setup and function of this embodiment are described below. One end of the mold is fitted onto the outside of an anti-stick ring 22, while one end of the mold support assembly 6 extends into the mold to support it. The electric push rod 53 pushes the slide table 51 to slide on the outside of the slide rail 52, causing the mold to move towards the other mold positioning plate 2 along with one mold positioning plate 2. This allows the other end of the mold to fit onto the outside of another anti-stick ring 22, completing the mold positioning. The drive motor 441 drives the speed changer 442, which in turn drives the second pulley 43 to rotate. Under the transmission of the transmission belt 42, The first pulley 41 drives the drive shaft 3 and a mold positioning plate 2 to rotate, ultimately driving the mold to rotate. The worker winds the glass fiber yarn onto the surface of the mold according to the corresponding winding process. During the winding process, the resin is blocked by the retaining ring 221 and will not adhere to one side of the mold positioning plate 2. The resin at the end of the mold will come into contact with the surface of the anti-stick ring 22. Because the anti-stick coating on the surface of the anti-stick ring 22 has low surface energy characteristics, it can greatly reduce the adhesion between the resin and the surface of the ring, making it easy to peel off the resin after curing during the winding process. This effectively prevents the resin from accumulating and curing at the end of the mold, significantly improving the demolding efficiency.

[0023] Example 2: Figures 1-3As shown, the winding molding equipment for fiberglass pipe production of this utility model includes a mounting platform 1. Mold positioning discs 2 are respectively provided at both ends of the mounting platform 1. A drive shaft 3 is fixedly connected to the center of one side of the mold positioning disc 2. A rotating assembly 4 is driven to the other end of one drive shaft 3. An mounting ring 21 is fixedly installed on the other side of the mold positioning disc 2. An anti-stick ring 22 is movably sleeved on the outer side of the mounting ring 21. A base 5 is movably passed through the other end of the other drive shaft 3. A slide table 51 is fixedly connected to one side of the base 5. A slide rail 52 is slidably connected to one side of the slide table 51. The slide 51 is fixedly installed above the mounting platform 1. One end of the slide 51 is provided with an electric push rod 53. The drive rod of the electric push rod 53 is fixedly connected to the other side of the slide 51. The mold support assembly 6 is fixedly installed on the outside of another drive shaft 3. The mold support assembly 6 includes a mounting plate 61 and several support rods 62. One end of the several support rods 62 is fixedly connected to one side of the mounting plate 61. The mounting plate 61 is fixedly installed on the outside of another drive shaft 3. The other end of the several support rods 62 movably passes through the interior of the mold positioning plate 2. The outer side of the several support rods 62 is movably sleeved with a soft sleeve 63.

[0024] The overall effect of this embodiment is that the several support rods 62 arranged in a ring array in the mold support assembly 6 form a multi-point support structure from the inside of the mold, ensuring that the mold maintains axial stability during positioning and high-speed rotation, and avoiding tilting or displacement. Each support rod 62 is fitted with a soft sleeve 63 at its end. The soft sleeve 63 is made of a highly elastic and wear-resistant polymer material, replacing the rigid support rod 62 in direct contact with the inner wall of the mold, and constructing a flexible buffer layer to effectively protect the inner surface of the mold from scratch damage and extend the service life of the mold.

[0025] The usage and working principle of this device are as follows: One end of the mold is fitted onto the outside of an anti-stick ring 22, while one end of the mold support component 6 extends into the mold to support it. The electric push rod 53 pushes the slide table 51 to slide on the outside of the slide rail 52, causing the mold to move towards the other mold positioning plate 2 along with one mold positioning plate 2. This allows the other end of the mold to be fitted onto the outside of another anti-stick ring 22, completing the positioning of the mold. The drive motor 441 drives the speed changer 442 to work, and the speed changer 442 drives the second pulley 43 to rotate. Under the transmission of the transmission belt 42, the first pulley 41 drives the transmission shaft 3 and a mold positioning plate 2 to rotate, ultimately driving the mold to rotate. The worker winds the glass fiber yarn onto the surface of the mold according to the corresponding winding process. During the winding process, the resin is blocked by the retaining ring 221 and will not adhere to one side of the mold positioning plate 2. The resin at the end of the mold will contact the surface of the anti-stick ring 22. Because the anti-stick coating on the surface of the anti-stick ring 22 has low surface energy characteristics, it can significantly reduce the adhesion between the resin and the surface of the ring.

[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
