Description

Technical Field

[0001] This invention relates to the field of fiberglass winding technology, and more specifically to a progressive fiberglass winding system. Background Technology

[0002] A fiberglass processing tower is a purification device. It is usually produced by extruding and winding fiberglass to create a cylindrical shell. This process not only ensures product consistency and quality stability, but also allows for the design of a tower structure with high strength and high corrosion resistance by controlling the winding angle and number of layers.

[0003] On automated production lines, the ratio of resin to fiberglass strips is controlled to ensure uniform material distribution in each part. The fiberglass strips are then wound onto a winding drum while adhesive is applied, causing the fibers to solidify in a columnar shape on the winding drum to form a shell of the required thickness. Dozens of fiberglass strips are wound onto the winding drum at the same time during the winding process. Since the thickness and quantity of fiberglass strips used in the production of different processing towers vary, multiple wiring holes on the wiring board are used to separate the individual fiberglass strips into a rectangular array to ensure the stability of the winding process before they are wound onto the winding drum.

[0004] Although the use of ribbon cable plates and ribbon cable holes allows the glass fiber strips to be separated and wound one by one, when the glass fiber strips that were originally on the same vertical line are wound on the winding drum, the glass fiber strips on top will press on the glass fiber strips on the bottom, forming a ring-shaped protrusion on the winding drum. There will be a noticeable depression between the two rings. The more horizontal the glass fiber strips, the more obvious this will be, resulting in an uneven surface of the formed glass fiber layer and the molding quality needs to be improved.

[0005] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to design a progressive glass fiber winding system that prevents the formation of annular protrusions when glass fiber strips arranged in a rectangular array are wound onto a winding cylinder, thereby ensuring the flatness and forming quality of the glass fiber layer and overcoming the aforementioned shortcomings in the technology.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a progressive glass fiber winding system for winding multiple rectangular arrayed glass fiber strips onto a winding drum, comprising a guide rail parallel to one side of the winding drum, a progressive trolley slidably mounted on the guide rail, and a cable tray mounted on the progressive trolley. The cable tray has multiple rectangular arrayed threading holes. A cable management shell is mounted on the progressive trolley, and multiple adjustable horizontal cable management lines are installed inside the cable management shell. Each cable management line has multiple arrayed cable management holes. A central shaft, a lower shaft, and an upper shaft are rotatably mounted inside the cable management shell. Each glass fiber strip passes through one threading hole and one cable management hole and passes between the central shaft and the lower shaft.

[0008] By using the fiber guide holes on the guide wire, the rectangular array of glass fiber strips is changed to a diamond array. This causes the glass fiber strips that were originally on the same vertical line to be horizontally staggered from top to bottom. They are then pressed to the same height by the central shaft to form a glass fiber surface, which is then guided by the upper shaft to the winding drum for winding.

[0009] Preferably, there is an included angle between the central axis and the central axis of the lower axis, and the outer peripheral surface of the lower axis is in contact with the glass fiber strip.

[0010] Preferably, one end of the cable management line has a threaded hole, and an adjusting rod that is rotatably connected to the cable management shell is threaded into the threaded hole. The other end of the cable management line has a blind hole, and a guide rod that is slidably connected to the cable management shell is installed in the blind hole.

[0011] Preferably, the guide rod is slidably connected to the cable management shell, and a spring is fixedly installed between the guide rod and the outer wall of the cable management shell.

[0012] Preferably, the end of the wire guide away from the adjusting rod is in contact with the inner wall of the wire guide housing, and when the guide rod is completely pulled out of the blind hole, the adjusting rod can be completely screwed out of the threaded hole.

[0013] Preferably, the bottom of the cable management shell has a receiving cavity containing vinyl ester resin adhesive, and the surface of the vinyl ester resin adhesive is in contact with the outer peripheral surface of the lower shaft.

[0014] Preferably, one end of the lower shaft passes through the cable management shell and is fixedly mounted with a driven wheel.

[0015] Preferably, a stop block is fixedly installed on the inner wall of the cable management shell, and there is a gap between the stop block and the outer peripheral surface of the central axis, and the side wall of the stop block is in contact with the glass fiber strip.

[0016] Preferably, the cable tray is vertically slidably connected to the cable management shell.

[0017] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0018] 1. This invention, through the design of the straightening lines and the central axis, can transform multiple glass fiber strips that were originally arranged in a rectangular array into a diamond array. The glass fiber strips that were originally on a vertical line are horizontally staggered from top to bottom, and then pressed onto the same horizontal plane by the central axis, forming a glass fiber surface that is wound around the winding cylinder, forming a flatter glass fiber layer to make a fiberglass processing tower.

[0019] 2. The present invention solves the problem in the prior art that when glass fiber strips on the same vertical line are wound on the winding cylinder, they will form piled-up protrusions, that is, a state of rings, and there will be obvious depressions between two adjacent rings, resulting in an uneven surface of the formed glass fiber layer.

[0020] 3. At the same time, the present invention has a lower shaft installed below the central shaft, and the central axes of the two are at an angle. With the help of the stop block, when the lower shaft applies force to the glass fiber strip on the central shaft, it will drive the glass fiber strip to move to the same side. After being blocked by the stop block, they come into contact with each other, forming a glass fiber surface with reduced gaps and a tighter surface, which further improves the flatness and forming quality of the glass fiber layer.

[0021] 4. In this invention, the lower shaft can also apply vinyl ester resin adhesive to the glass fiber surface when it rotates, eliminating the need to use the existing coating device to apply vinyl ester resin adhesive to the glass fiber strip wound on the winding drum.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] This invention provides, for example Figure 1-6The illustrated progressive glass fiber winding system is used to uniformly wind multiple rectangular arrays of glass fiber strips 1 onto a winding drum 2. It includes a guide rail 3 parallel to one side of the winding drum 2 (as in the prior art), a progressive carriage 4 slidably mounted on the guide rail 3, and a cable management plate 5 mounted on the progressive carriage 4. The cable management plate 5 has multiple rectangular arrays of threading holes 6, the same number as the glass fiber strips 1. A cable management shell 7 with an inner cavity is fixedly mounted on the progressive carriage 4. The cable management shell 7 has the same number of cable management lines 8 as the number of rows of threading holes 6. Each cable management line 8 has the same number of cable management holes 9 as the number of columns of threading holes 6, evenly distributed. A glass fiber strip 1 passes through one threading hole 6 and then through the corresponding cable management hole 9, ensuring that the glass fiber strip 1 and the cable management holes... 9 and the threading hole 6 correspond one-to-one. To prevent the glass fiber strips 1, which are arranged in a rectangular array after passing through the threading hole 6, from piling up and protruding on the same vertical line when wound onto the spool, we horizontally stagger the aligning lines 8 from top to bottom. This causes the glass fiber strips 1 to form a diamond array after passing through the aligning hole 9. At this point, the glass fiber strips 1 that were originally on the same vertical line will be horizontally staggered. Then, we rotate and install the central shaft 10 inside the aligning housing 7. The central shaft 10 will press all the glass fiber strips 1 onto the same plane, completing the change from a diamond array distribution to a glass fiber surface. Now, with the glass fiber surface wound onto the spool, the glass fiber strips 1 on the same vertical line will not pile up and protrude. To ensure the uniformity of winding and reduce the size of the glass fiber... The spacing between the fiberglass strips 1 makes the glass fiber surface they form more compact. A lower shaft 11 is rotatably mounted below the central shaft 10. A driven wheel 17 is fixedly mounted at the end of the lower shaft 11, creating an angle between the central axis of the lower shaft 11 and the central axis of the central shaft 10. Simultaneously, the lower shaft 11 contacts and compresses the glass limiting strip on the central shaft 10. When the driven wheel 17 drives the lower shaft 11 to rotate, because of the angle between the central axis of the lower shaft 11 and the central axis of the central shaft 10, the oblique force exerted by the lower shaft 11 on the glass fiber strips 1 on the central shaft 10 is decomposed into forces perpendicular to the central axis of the central shaft 10 and forces parallel to the central axis. The force parallel to the central axis pushes the glass fiber strips 1 on the central shaft 10 towards one end of the central shaft 10. At this time, a fixed... A stop block 18 with a certain gap from the outer circumference of the central shaft 10 is installed. After the glass fiber strip 1 contacts the stop block 18, it cannot move further. This allows the glass fiber strips 1 to contact each other, thus forming a glass fiber surface with reduced gaps and a tighter surface. Then, an upper shaft 12 is rotatably installed inside the cable management shell 7. The glass fiber surface is wound onto the winding drum 2 via the upper shaft 12. The bottom of the inner cavity of the cable management shell 7 has a receiving cavity 16 containing vinyl ester resin. The surface of the vinyl ester resin is in contact with the outer circumference of the lower shaft 11. In this way, when the lower shaft 11 rotates, the vinyl ester resin can be applied to the glass fiber surface, eliminating the need to use the existing application device to apply the vinyl ester resin to the glass fiber strip 1 wound on the winding drum 2.To facilitate the replacement of cable trays 5 with varying numbers of wire holes 6, the cable tray 5 is vertically slidably mounted on the cable management housing 7. To allow the cable management line 8 to be changed and adjusted horizontally to form rhombuses with different angles, a threaded hole is provided at one end of the cable management line 8. An adjusting rod 13, rotatably connected to the cable management housing 7, is threaded into the threaded hole. A blind hole is provided at the other end of the cable management line 8, within which a guide rod 14, mounted on the cable management housing 7, is slidably connected. Rotating the adjusting rod 13 allows adjustment of the horizontal position of the cable management line 8 on the adjusting rod 13 via the threaded connection. The guide rod 14 is slidably connected to the cable management housing 7, and a spring 15 is fixedly installed between the guide rod 14 and the outer wall of the cable management housing 7. When the end of the cable management line 8 away from the adjusting rod 13 is flush with the inner wall of the cable management housing 7, and the guide rod 14 is completely withdrawn from the blind hole, the adjusting rod 13 can be completely unscrewed from the threaded hole. This allows for easy replacement of the cable management line 8.

[0034] When using this system, the number of cable management strips 8 and the number of cable management holes 9 on the cable management strips 8 are selected according to the number of rows and columns of the cable holes 6 on the cable board 5. Then, the guide rod 14 is pulled to stretch the spring 15. The threaded holes on the cable management strips 8 are aligned with the adjusting rod 13, and the guide rod 14 is aligned with the blind hole. Then, the guide rod 14 is released, allowing the spring 15 to drive the guide rod 14 to reset and insert it into the blind hole. Then, the adjusting rod 13 is rotated into the threaded hole to adjust the horizontal position of the cable management strips 8 as needed, so that the cable management holes 9 on the multiple cable management strips 8 form the required diamond shape. Then, multiple fiberglass strips 1 are passed through the corresponding cable holes 6 and cable management holes 9, and then passed between the central shaft 10 and the lower shaft 11. Finally, as shown in the figure... Figure 5 As shown, the fiberglass surface is wound around the upper shaft 12 to form a glass fiber surface. Then, the glass fiber surface is wound around the winding drum 2 and the advance car 4 is started to move along the guide rail 3.
