Description

Technical Field

[0001] This utility model relates to the field of glass fiber tube production technology, and in particular to a glass fiber cloth roll feeding mechanism. Background Technology

[0002] Existing fiberglass tube production lines typically employ a continuous production process. First, a roll of fiberglass cloth is unwound from a winding rack and wrapped around a guide post. Next, the fiberglass bundle is peeled off by winding and impregnated with resin to form a tube blank. An additional layer of fiberglass cloth can be laid on the outside of the tube blank in the same manner to enhance its performance. Subsequently, the tube blank is fed into a heat curing zone. Under high temperature, the resin fully cross-links, forming a fiberglass tube with specific rigidity. After curing, the fiberglass tube is advanced by a traction device, cut to length online, and then leaves the production line.

[0003] However, existing fiberglass cloth wrapping devices have some problems. For example, patent number CN202220727459.1, entitled "A Composite Pipe Braided Tape Wrapping Device," involves passing the unwound fiberglass cloth through a wrapping mechanism with a curved surface structure, turning the flatly laid fiberglass cloth into a ring shape and laying it on the outside of the guide post. While this design achieves wrapping of the fiberglass cloth to a certain extent, the subsequent processes of winding fiberglass bundles, impregnating with resin, and heat curing result in a relatively slow output speed of the fiberglass from the traction device. To improve production efficiency, the output speed of the traction component can be increased when winding fiberglass bundles, impregnating with resin, and heat curing are not required; this leads to inconsistent output speeds of the fiberglass tube.

[0004] Because the relative position of the wrapping mechanism and the guide column is fixed, the slow traction speed will result in insufficient tension of the glass fiber cloth by the wrapping mechanism of the curved structure. This may cause the glass fiber cloth to become loose, wrinkled or unevenly distributed, affecting the forming quality of the glass fiber tube. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a glass fiber cloth roll feeding mechanism that can ensure the forming quality of glass fiber tubes.

[0006] To solve the above-mentioned technical problems, the present invention provides a glass fiber cloth roll feeding mechanism, including an unwinding frame for unwinding glass fiber cloth into a roll, guide columns extending forward and backward, a guide plate for guiding the unwound glass fiber cloth and wrapping it around the outside of the guide columns, and a first adjustment component for changing the forward and backward position of the guide plate. The first adjustment component includes a first servo push rod installed on the unwinding frame for driving the guide plate to move forward and backward, and a controller communicatively connected to the first servo push rod.

[0007] As an improvement to the above solution, a connecting frame is provided on the rear side of the unwinding frame, and the first servo push rod is mounted on the connecting frame and positioned behind the guide plate.

[0008] As an improvement to the above solution, the guide plate is provided with multiple sliding rods extending backward at intervals on the left and right sides, and the connecting frame is provided with multiple sliding holes for corresponding sliding connections with the sliding rods.

[0009] As an improvement to the above solution, the first adjustment component also includes multiple springs that are fitted one-to-one onto the slide rod and disposed between the connecting frame and the guide plate.

[0010] As an improvement to the above solution, the first adjustment component also includes a pressure sensor mounted on the connecting frame and communicating with the controller. The front and rear ends of the spring abut against the rear side of the guide plate and the front side of the pressure sensor, respectively. The pressure sensor is provided with a plurality of clearance through holes with an inner diameter larger than the outer diameter of the slide rod and corresponding to the slide rod for passage.

[0011] As an improvement to the above solution, the first adjustment component also includes a display and a control panel that are communicatively connected to the controller.

[0012] As an improvement to the above solution, the unwinding frame is provided with an unwinding roller for mounting the rolled glass fiber cloth and a guide roller positioned above the guide plate and the unwinding roller.

[0013] As an improvement to the above solution, the glass fiber cloth roll feeding mechanism of this utility model also includes a second adjustment component for adjusting the up and down position of the guide roller.

[0014] As an improvement to the above solution, the second adjustment component includes two sliders that are slidably connected to the unwinding frame and rotatably connected to the left and right ends of the guide roller, and two second servo push rods that are used to drive the two sliders to move up and down synchronously. The second servo push rods are communicatively connected to the controller.

[0015] Implementing this utility model has the following beneficial effects:

[0016] The fiberglass cloth roll feeding mechanism of this utility model, through the cooperation of the unwinding frame, guide column, guide plate, first servo push rod and controller, can move the first servo push rod and guide plate forward when the output speed of the external traction component is slow. This increases the degree of contact between the fiberglass cloth and the guide plate, reduces the occurrence of looseness, wrinkles or uneven distribution of the fiberglass cloth, and ensures the forming quality of the fiberglass tube.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1 to 5As shown, a fiberglass cloth roll feeding mechanism in this embodiment of the present invention includes an unwinding frame 100 for unwinding fiberglass cloth into a roll, guide posts 200 extending forward and backward, a guide plate 300 for guiding and wrapping the unwound fiberglass cloth to the outside of the guide posts 200, and a first adjustment component for changing the forward and backward position of the guide plate 300. The first adjustment component includes a first servo push rod 400 mounted on the unwinding frame 100 for driving the guide plate 300 to move forward and backward, and a controller 420 communicatively connected to the first servo push rod 400. In practice, the unwinding frame 100 can be detachably equipped with rollers for passing through the central through-hole of the rolled fiberglass cloth, or it can be an unwinding mechanism as described in patent number CN202220727459.1, entitled "A Composite Pipe Braided Tape Wrapping Device," capable of unwinding the rolled fiberglass cloth in a flat manner. The guide plate 300 can be a wrapping mechanism as described in patent number CN202220727459.1, entitled "A Composite Pipe Braided Tape Wrapping Device," capable of shaping the flatly laid fiberglass cloth roll into a ring shape and laying it on the outside of the guide post 200. The controller 420 can be an intelligent control unit with a PLC or similar, which communicates with the external traction component to achieve real-time reading of the traction component's speed. For example, the external traction component can be a servo traction mechanism, or a speed detector can be added to the traction component to obtain the output speed of the traction component; how to obtain the output speed of the traction component will not be elaborated here. By reading the speed of the external traction component, the controller 420 can control the first servo push rod 400 to change the front and rear position of the guide plate 300 on the guide post 200, thereby changing the degree of adhesion between the guide plate 300 and the fiberglass cloth.

[0033] The specific working principle of the fiberglass cloth roll feeding mechanism of this utility model is as follows: When the controller 420 reads that the output speed of the external traction component is slow, the controller 420 controls the first servo push rod 400 and the guide plate 300 to move forward, increasing the adhesion between the fiberglass cloth and the guide plate 300 and reducing the occurrence of looseness, wrinkles, or uneven distribution of the fiberglass cloth; when the controller 420 reads that the output speed of the external traction component is fast, the controller 420 controls the first servo push rod 400 and the guide plate 300 to move backward, preventing the fiberglass cloth from being too tightly adhered to the guide plate 300. As for the specific forward and backward movement distances, these are determined based on the output speed of the external traction component, the size of the fiberglass cloth, and through multiple experimental measurements, and will not be described in detail here.

[0034] The fiberglass cloth roll feeding mechanism of this utility model, through the cooperation of the unwinding frame 100, guide column 200, guide plate 300, first servo push rod 400 and controller 420, can, when the output speed of the external traction component is slow, control the first servo push rod 400 and guide plate 300 to move forward, increase the fit between the fiberglass cloth and guide plate 300, reduce the occurrence of looseness, wrinkles or uneven distribution of fiberglass cloth, and ensure the forming quality of fiberglass tube.

[0035] Specifically, a connecting frame 110 is provided on the rear side of the unwinding frame 100, and the first servo push rod 400 is preferably mounted on the connecting frame 110 and positioned behind the guide plate 300. In fact, the connecting frame 110 provides a connecting component for the mounting of the first servo push rod 400, and since the fiberglass cloth contacts the front side of the guide plate 300, placing the first servo push rod 400 on the guide plate 300 avoids contact with the fiberglass cloth, making the layout of the first servo push rod 400 more reasonable.

[0036] More specifically, the guide plate 300 preferably has multiple rearwardly extending slide rods 310 spaced apart on its rear side, and the connecting frame 110 has multiple sliding holes 120 for corresponding sliding connections with the slide rods 310. The two slide rods 310 and two sliding holes 120 shown in the accompanying drawings of this embodiment can be varied in number according to actual applications. By having multiple slide rods 310 and multiple sliding holes 120 corresponding one-to-one, the guide plate 300 and the connecting frame 110 can be slidably connected. This ensures that when the first servo push rod 400 moves the guide plate 300, it can move along a line parallel to the axis of the guide column 200, thus ensuring the accuracy of the front-to-back position adjustment of the guide plate 300.

[0037] It is worth mentioning that the first adjustment component preferably also includes multiple springs 430, each correspondingly sleeved on the slide rod 310 and disposed between the connecting frame 110 and the guide plate 300. When the first servo push rod 400 moves the guide plate 300 forward to contact the fiberglass cloth, it is easy to cause impact to the fiberglass cloth. Under the action of the springs 430, the guide plate 300 will compress the springs 430 after contacting the fiberglass cloth, thereby prolonging the contact time between the guide plate 300 and the fiberglass cloth, reducing the impact on the fiberglass cloth, and reducing the probability of damage to the fiberglass cloth.

[0038] Furthermore, the first adjustment assembly preferably includes a pressure sensor 440 mounted on the connecting frame 110 and communicatively connected to the controller 420. The front and rear ends of the spring 430 abut against the rear side of the guide plate 300 and the front side of the pressure sensor 440, respectively. The pressure sensor 440 has multiple clearance holes 441 with an inner diameter larger than the outer diameter of the slide rod 310, each corresponding to a passage for the slide rod 310 to pass through. This prevents the slide rod 310 from colliding with the pressure sensor 440 during its forward and backward movement relative to the pressure sensor 440, thus avoiding any impact on the detection accuracy of the pressure sensor 440. By adding the pressure sensor 440, the force exerted by the spring 430 on the pressure sensor 440 can be detected, thereby inferring the degree of adhesion between the guide plate 300 and the fiberglass cloth, as well as the tension of the fiberglass cloth. This provides a more intuitive parameter basis for adjusting the forward and backward movement distances of the guide plate 300.

[0039] Furthermore, the first adjustment component preferably includes a display 450 and a control panel 460 that are communicatively connected to the controller 420. The display 450 and control panel 460 can be common computer accessories (such as a screen and keyboard lights), enabling the operator to obtain the detection data from the pressure sensor 440 and adjust the operating parameters of the first servo push rod 400.

[0040] It should be noted that the unwinding frame 100 preferably includes an unwinding roller 130 for mounting the rolled fiberglass cloth and a guide roller 140 positioned above and between the guide plate 300 and the unwinding roller 130. When the speed output by the external traction assembly remains stable, through the synergistic action of the unwinding roller 130 and the guide roller 140, the fiberglass cloth can be smoothly unwound from the unwinding roller 130 at a relatively stable angle and guided to the front side of the guide plate 300, ensuring the stability of the fiberglass cloth during the unwinding process.

[0041] It is worth mentioning that the fiberglass cloth roll feeding mechanism of this utility model preferably includes a second adjusting component 500 for adjusting the vertical position of the guide roller 140. When the output speed of the external traction component slows down, the rolled fiberglass cloth continues to unwind under inertia, which may cause the fiberglass cloth between the guide roller 140 and the guide plate 300 to loosen. At this time, by raising the position of the guide roller 140 through the second adjusting component 500, the tension of the fiberglass cloth can be increased, thereby reducing the loosening phenomenon. After a certain period of time, the second adjusting component 500 will drive the guide roller 140 to move down and reset, further reducing the looseness, wrinkles or uneven distribution of the fiberglass cloth after winding. It is worth noting that the reset waiting time of the second adjusting component 500 is determined by a combination of factors such as the output speed of the external traction component, the forward movement distance of the guide plate 300 and the size of the fiberglass cloth, which will not be elaborated here.

[0042] Specifically, the second adjustment component 500 preferably includes two sliders 510 that are slidably connected to the unwinding frame 100 and rotatably connected to the left and right ends of the guide roller 140, and two second servo push rods 520 that are used to drive the two sliders 510 to move up and down synchronously. The second servo push rods 520 are communicatively connected to the controller 420. In fact, the two second servo push rods 520 are symmetrically arranged to drive the two sliders 510 to move up and down synchronously, thereby realizing the adjustment of the vertical position of the guide roller 140, thus realizing the function of changing the vertical position of the guide roller 140.

[0043] The above are merely specific embodiments of this utility model and do not limit the patent scope of this utility model. Although embodiments of this utility model have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the claims and their equivalents. Those skilled in the art can make various other corresponding changes and modifications based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model.
