Description

Technical Field

[0001] The utility model relates to the technical field of fiber winding, in particular to a fiber winding mechanism for producing fiber glass tubes. Background Art

[0002] The forming process of glass fiber tube is to impregnate glass fiber filaments with resin, solidify them in a high-speed polymerization device integrating light, electricity and heat, and then form them by traction and extrusion. Due to the different types of resins used, there are polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics, and phenolic glass fiber reinforced plastics. They are light and hard, non-conductive, high in mechanical strength, anti-aging, high temperature resistance, and corrosion resistance.

[0003] At present, there are three main types of glass fiber tube production processes: reciprocating fiber winding process, continuous fiber winding process and centrifugal casting process. Among them, the reciprocating fiber winding process is the most widely used, that is, the dipping tank reciprocates with the rotating mandrel, and the long fiber glass filaments are placed at a certain angle relative to the mandrel axis. The auxiliary angle (i.e. the winding angle) is controlled by the ratio of the moving speed of the dipping tank and the rotation speed of the mandrel. The translational movement of the dipping tank is controlled by computerized electromechanical control. The number of winding layers is gradually increased until the designed wall thickness is reached. After the winding is completed, the resin in the product is basically solidified. After solidification, the mandrel is removed from the FRP tube.

[0004] Regardless of whether a reciprocating fiber winding process or a continuous fiber winding process is adopted, the production process usually requires the use of a fiber winding machine to wind fiber glass, resin and other materials on a mold to form a tubular structure. The fiber winding mechanism of a traditional fiber winding machine usually adopts a one-time molding mechanism and cannot perform continuous operation. The glass fiber tube on the mold after being wound by the fiber winding machine usually requires manual operation to remove the core film, and the fiber winding machine is usually in a standby state during the operation. Subsequent winding work can only be carried out after the manual operation is completed, which not only reduces work efficiency, but also increases the complexity, repeatability and even danger of manual operation. Although there are fiber winding machines on the market that can simultaneously produce batches of glass fiber tubes, the setting of their fiber winding mechanisms usually makes the overall structure of such fiber winding machines highly similar and complex, which not only makes the overall size of such equipment larger and occupies a certain amount of use space, but also further increases the failure rate of the equipment, and further increases the inconvenience of manual operation and maintenance. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.

[0026] See also Figure 1-3The present embodiment relates to a fiber winding mechanism for producing fiber glass tubes, comprising a frame 1, a supply assembly 2 for conveying fiber raw materials, and a molding assembly 3, wherein the supply assembly 2 is slidably arranged on the frame 1 and driven to slide by a first driving component 101 arranged at the bottom, and the molding assembly 3 is fixed on the frame 1 and is placed at one end of the supply assembly 2, and comprises a rotating frame 31, wherein the rotating frame 31 is rotatably arranged on the frame 1 and driven to rotate by a second driving component 102 arranged on the frame 1, and a plurality of winding shafts 4 and auxiliary shafts 5 are rotatably arranged on the rotating frame 31, and the plurality of winding shafts 4 and auxiliary shafts 5 are surrounded and staggered on the rotating frame 31, and a third driving component 103 is arranged on the frame 1 and connected and drives the winding shaft 4 to rotate through a pneumatic chuck 6, and triggers are connected at both ends of the auxiliary shaft 5 on the rotating frame 31, and a cutting assembly 7 for fiber cutting is also slidably arranged on the rotating frame 31 and is placed on one side of the auxiliary shaft 5, and the cutting assembly 7 is driven to slide by a fourth driving component 104 arranged on the rotating frame 31.

[0027] Specifically in this embodiment, the signal lines of the first driving component 101, the second driving component 102, the third driving component 103, the fourth driving component 104, the pneumatic chuck 6 and the trigger are respectively connected to their signal lines through the controller, and the fiber raw material can be transported by the supply component 2. The frame 1 is provided with a slide rail 11. The supply component 2 is driven by the first driving component 101 at the bottom to slide left and right on the slide rail 11 of the frame 1. At the same time, the rotating frame 31 is driven by the second driving component 102 to The winding shaft 4 is rotated so that the winding shaft 4 is placed on one side of the supply component 2 and fixed, and the third driving component 103 is connected to the winding shaft 4 through the pneumatic chuck 6 and driven to rotate, and the fiber raw material is wound on the winding shaft 4 under the action of the supply component 2 slidably arranged on the frame 1. Specifically, after the fiber raw material on the supply component 2 is output to a certain amount, that is, after the glass fiber raw material on the winding shaft 4 is wound to a certain amount, the winding shaft 4 stops rotating under the drive of the third driving component 103, so that the fiber raw material on the supply component 2 is suspended from being transported. At the same time, see Figure 3 As shown, the pneumatic chuck 6 provided on the third driving component 103 is opened and retracted, thereby disconnecting from the winding shaft 4. After the pneumatic chuck 6 is moved, the second driving component 102 can drive the rotating frame 31 to rotate after receiving the signal through the controller so that the next winding shaft is placed on the side of the supply component 2, and the pneumatic chuck 6 is adapted to retract and clamp so that the third driving component 103 drives the corresponding winding shaft 4 to rotate. The plurality of winding shafts 4 and auxiliary shafts 5 are surrounded and staggered on the rotating frame 31. For details, see Figure 1 or Figure 2As shown in the figure, the winding reel 4 and the auxiliary shaft 5 are arranged on the rotating frame 31 in sequence, and the auxiliary shaft 5 is arranged between adjacent winding reels 4. The glass fiber 100 on the previous winding reel 4 is rotated by the rotating frame 31 to be pulled onto the next winding reel, and contacts with the auxiliary shaft 5 rotatingly arranged between the adjacent winding reels 4 on the rotating frame 31. During the process of the auxiliary shaft 5 contacting and adapting to the glass fiber 100, the triggers arranged at both ends of the auxiliary shaft 5 are triggered and send a trigger signal to the controller. After receiving the trigger signal, the controller sends a trigger signal to the fourth driving component 1 04 sends a trigger signal, and the fourth driving component 104 can drive the cutting component 7 placed on one side of the auxiliary shaft 5 to slide after receiving the trigger signal. Specifically, the fourth driving component 104 uses a ball screw to drive the cutting component 7 to slide along its screw shaft 1041 on the rotating frame 31. During the sliding process of the cutting component 7, the glass fiber 100 on the winding shaft 4 and the auxiliary shaft 5 can be driven to slide to a certain distance and cut off, completing the disconnection of the glass fiber 100 between adjacent winding shafts 4. At the same time, since the glass fiber 100 has a certain viscosity after being soaked in resin , so that the two ends of the cut surface of the glass fiber 100 cut by the cutting component 7 are in contact with the shaft wall surface of the winding reel 4 and the auxiliary shaft 5, with a certain tensile stress without affecting the winding of the glass fiber 100 around the next reel 4, and under the drive of the third driving component 103, the supply component 2 and the first driving component 101 work together to complete the fiber winding process of the next reel 4, and repeat the above operation process to realize the fiber winding molding of multiple glass fiber tubes. At the same time, the size of the rotating frame 31 and the number of the winding reel 4 and the auxiliary shaft 5 can be adjusted according to the actual use. Different models can be selected according to needs. The fiber winding machine using this fiber winding mechanism can achieve continuous operation, reduce the repeatability of manual operation, and further improve work efficiency. At the same time, the overall structure of the molding component 3 is simple and compact, which further reduces the space occupation and reduces the difficulty of manual operation, making it convenient for daily inspection and later maintenance. In addition, the operator can easily observe and adjust the winding shaft 4 after the fiber raw material is wound on the rotating disk, and make timely adjustments according to abnormal situations, so as to further improve the fiber winding uniformity and molding quality of the glass fiber tube.

[0028] See also Figure 4The two ends of the auxiliary shaft 5 are slidably arranged on the rotating frame 31 through the slide grooves 311 arranged on the rotating frame 31. The slide grooves 311 are provided with compression springs 312 connected to the two ends of the auxiliary shaft 5 respectively. Specifically, when the adjacent winding shafts 4 are rotated by the rotating disk to switch the fiber raw material winding, when the glass fiber 100 contacts the auxiliary shaft 5, the auxiliary shaft 5 is subjected to a certain tensile stress to make it slide adaptively along the slide grooves 311 arranged on the rotating disk. At the same time, the compression springs 312 arranged in the slide grooves 311 are Under the action, a certain compressive stress is exerted on the auxiliary shaft 5, thereby exerting a certain buffering and stress effect on the glass fiber yarn 100, thereby reducing the phenomenon that the glass fiber yarn 100 is stretched, deformed or even broken due to the rotation of the rotating disk during the continuous operation of this fiber winding mechanism and its switching around the reel 4, which affects the winding and molding effects. At the same time, the design of this auxiliary shaft 5 can also further improve the fit and tightness of the glass fiber yarn 100 and the auxiliary shaft 5 under the action of the compression spring 312, thereby ensuring the cutting accuracy of the cutting component 7 and the smoothness of the cut surface.

[0029] The auxiliary shafts 5 are arranged in two groups side by side and are arranged around the winding shaft 4 and are distributed on the rotating frame 31 in an interlaced manner. The cutting assembly 7 is placed between the two groups of auxiliary shafts 5 and is adapted to be provided with multiple groups, such as Figure 2 As shown in the figure, the two sets of auxiliary shafts 5 distributed side by side can further reduce the suspended length of the glass fiber yarn 100 of the winding shaft 4 on the rotating disk during the winding switching process, making its transition smoother and having a certain buffering effect, which can further improve the cutting stability of the cutting component 7 between the two sets of auxiliary shafts 5.

[0030] The fourth driving component 104 is driven by a ball screw, and the screw shaft 1041 adopts a forward and reverse double-rotation structure. The cutting component 7 is provided with two groups of adaptors slidably arranged at both ends of the screw shaft 1041. When the screw shaft 1041 adopting the forward and reverse double-rotation structure is driven to rotate by the fourth driving component 104, the two groups of cutting components 7 on the screw shaft 1041 are placed in the middle of the screw shaft 1041, and are driven by the screw shaft 1041 to slide toward both ends along the middle of the screw shaft 1041, so that the glass fiber 100 in contact with the auxiliary shaft 5 is not affected by its contact position, thereby further improving the operation efficiency of the cutting component 7, and further improving the cutting effect while improving the cutting accuracy and stability of the cutting component 7.

[0031] See also Figure 5The cutting assembly 7 includes a cutting knife, and the cutting knife includes a knife head 71 and a knife seat 72. The two groups of cutting assemblies 7 on the screw shaft 1041 are adapted and fitted through the connecting portion 721 provided on the knife seat 72. The two groups of cutting knives on the screw shaft 1041 are fitted through the connecting portions 721 provided on the knife seat 72, respectively, so that the two groups of cutting assemblies 7 placed in the middle of the screw shaft 1041 can reach the lower knife head 71 through the connecting portion 721 on the knife seat 72 for the glass fiber filaments 100 at different contact positions on the auxiliary shaft 5 so that they can all be cut, thereby ensuring the comprehensiveness and accuracy of the cutting.

[0032] The connecting portion 721 adopts an elastic structure to connect to the knife seat 72, and a plurality of annular protrusions 7211 are further provided on the connecting portion 721. The connecting portion 721 adopting the elastic structure enables the cutting component 7 to play a certain buffering and protective role in contacting the glass fiber 100 during the sliding process, thereby reducing the phenomenon of deformation or even premature breakage. At the same time, a plurality of annular protrusions 7211 are provided on the connecting portion 721, which can further reduce the phenomenon of the glass fiber 100 contacting the connecting portion 721 during the sliding cutting process of the cutting component 7, and can make the glass fiber 100 stably pass through the connecting portion 721 on the knife seat 72 to reach the lower knife head 71 for cutting, thereby reducing the degree of damage to the fiber raw material and further improving the cutting stability.

[0033] The supply assembly 2 adopts a roller conveying structure, and a plurality of rollers 21 are rotatably arranged on the supply assembly 2. The plurality of rollers 21 are arranged in different sizes and are arranged in a vertically scattered manner on the supply assembly 2. Figure 1 As shown, the plurality of rollers 21 arranged in this manner have a larger span, so that the fiber raw material has a certain ductility during the conveying process, and at the same time further improves the stability of the supply component 2 during the fiber raw material conveying process, reduces fluctuations, deviations and even knotting during the conveying process, and is convenient for the inspection and adjustment of the fiber raw material.

[0034] The winding shaft 4 is rotatably arranged on the rotating frame 31 through the detachable structure of the rotating frame 31. Figure 6 As shown, the rotating frame 31 is equipped with a matching connector through a detachable structure of bolts or snaps, and the winding shaft 4 is installed on the rotating disk through the connector, so that the installation, disassembly and replacement of the winding shaft 4 can be convenient. The winding shaft 4 of matching size can be selected according to the different sizes of the required glass fiber tubes to meet different usage requirements. At the same time, by replacing the new winding shaft 4, the working continuity and working efficiency of this fiber winding mechanism can be further improved.

[0035] The winding shaft 4 is provided with outer edges 41 at both ends, and multiple groups of notches 411 are opened on the outer edges 41. During the winding switching process of the winding shaft 4, the outer edges 41 and the multiple groups of notches 411 opened on the winding shaft 4 can drive the glass fiber yarn 100 to slide to the two ends of the winding shaft for cutting after the cutting component 7 drives the glass fiber yarn 100 to slide to the two ends of the winding shaft for cutting. The broken glass fiber yarn 100 can be clamped through the multiple groups of notches 411 opened on the outer edges 41 under the rotation of the winding shaft 4 and be preliminarily wound on the winding shaft 4 along the outer edges 41, thereby further improving the stability of the winding switching process of the winding shaft 4, reducing the phenomenon that the glass fiber yarn 100 falls off and separates from the winding shaft 4 and affects the winding process, and improving the operation efficiency and operation stability of this fiber winding mechanism.

[0036] The rotating frame 31 is installed on the frame 1 through a detachable structure. The two ends of the rotating frame 31 are adapted to be installed on the frame 1 through the installation grooves 12 provided on the frame 1 and connected with the second driving component 102 and the fourth driving component 104. Therefore, the rotating frame 31 installed on the frame 1 through the detachable structure is convenient for installation, disassembly and replacement, and is convenient for cleaning and maintenance. At the same time, the rotating frame 31 of an appropriate size can be selected according to different usage requirements, and an appropriate number of winding shafts 4 and auxiliary shafts 5 can be matched to adapt to different usage conditions, thereby further improving the applicability of this fiber winding mechanism.
