Description

Technical Field

[0001] This utility model relates to the field of plastic profile manufacturing technology, specifically to an online unwinding and hot lamination device for UD tape. Background Technology

[0002] Currently, in the production of plastic profiles, by thermally bonding fiberglass UD tape to the upper and lower surfaces of PP substrates online, the tensile strength, rigidity, and impact resistance of the products are improved, making it possible for PP materials to replace traditional steel scaffolding planks. Products produced in this way offer advantages such as light weight, moisture resistance, corrosion resistance, insulation, and ease of transportation and storage.

[0003] For example, the patent with announcement number CN217741425U discloses a cutting motor bracket, which is inserted into the inside of the housing by rotating an air shaft. The transmission disc is fixedly sleeved on one end of the air shaft inserted into the housing. The braking mechanism is connected to the housing to control the rotation of the transmission disc. This allows for quick assembly and disassembly of the aluminized film roll, control of the unwinding tension of the aluminized film roll, and ensures processing quality. However, this patent has only one unwinding device, which has low working efficiency and no online correction structure, and cannot meet the needs of high efficiency and flexible operation in automated composite processes.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide an online unwinding and thermal recombining device for UD tape, so as to improve efficiency and prevent deviation.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: an online unwinding and hot composite device for UD tape, including a frame and a movable frame, a fixed plate is fixedly installed on the frame, a crane is installed on the top of the fixed plate, an upper unwinding device is installed on the top of the fixed plate, and a preheater is installed on one side of the frame;

[0007] A base is fixedly installed at the bottom of the frame, the movable frame is slidably assembled with the base, a guide bracket is slidably assembled on the movable frame, a lower unwinding device is installed on the top of the guide bracket, a guide block is fixedly installed on the top of the guide bracket, a support block is fixedly installed on the top of the movable frame, a lead screw is rotatably installed on the guide block, the lead screw is threadedly connected to the support block, and a handwheel is fixedly installed at one end of the lead screw.

[0008] Furthermore, a connecting plate is fixedly connected to one side of the movable frame, and a horizontal wheel is fixedly connected to the bottom of the connecting plate by bolts.

[0009] Furthermore, a roller guide rail is fixedly installed on the top of the base, and a roller body is rotatably mounted on the movable frame, with the roller body and the roller guide rail in a rolling connection.

[0010] Furthermore, the support block has a threaded hole that penetrates it, and the lead screw is threadedly connected to the threaded hole.

[0011] Furthermore, a limiting plate is fixedly installed on one side of the movable frame, a rotating block is rotatably installed on the top of the base, a screw is rotatably installed on the rotating block, and the limiting block and the fixing block are threadedly connected to the screw.

[0012] Furthermore, a guide rail is fixedly connected to the top of the movable frame by screws, and a slider is fixedly connected to the bottom of the guide bracket by screws, with the slider slidably connected to the guide rail.

[0013] The beneficial effects of this application are as follows: During production, the upper and lower unwinding devices are started simultaneously, and the UD roll material installed on the roll is laminated onto the PP substrate. The dual-station operation improves efficiency. When the roll material of the lower unwinding device is exhausted, the operator holds the handle and pulls it off the frame along the roller guide rail. The empty roll is unloaded and a new roll is loaded by the crane, and then pushed back to the station. During the lamination process, if the UD belt deviates laterally, the corresponding side handwheel is rotated to drive the screw drive support block and guide bracket to move laterally along the guide rail, thereby realizing online correction and avoiding deviation after the crane loads the roll.

[0021] To make the content of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0022] like Figure 1-5 As shown, this application provides an online unwinding and hot composite device for UD tape, including a frame 5 and a movable frame 10. A fixed plate 6 is fixedly installed on the frame 5, a crane 1 is installed on the top of the fixed plate 6, an upper unwinding device 2 is installed on the top of the fixed plate 6, and a preheater 4 is installed on one side of the frame 5.

[0023] A base 7 is fixedly installed at the bottom of the frame 5. The movable frame 10 is slidably assembled with the base 7. A guide bracket 12 is slidably assembled on the movable frame 10. A lower winding device 3 is installed on the top of the guide bracket 12. A guide block 14 is fixedly installed on the top of the guide bracket 12. A support block 16 is fixedly installed on the top of the movable frame 10. A lead screw 13 is rotatably installed on the guide block 14. The lead screw 13 is threadedly connected to the support block 16. A handwheel 15 is fixedly installed at one end of the lead screw 13.

[0024] like Figure 1-5 As shown, a connecting plate 9 is fixedly connected to one side of the movable frame 10, and a horizontal wheel 11 is fixedly connected to the bottom of the connecting plate 9 by bolts.

[0025] like Figure 1-5 As shown, a roller guide rail 8 is fixedly installed on the top of the base 7, and a roller body 17 is rotatably installed on the movable frame 10. The roller body 17 is rotatably connected to the roller guide rail 8. A threaded hole is opened inside the support block 16, and the screw 13 is threadedly connected to the threaded hole. A limit plate 18 is fixedly installed on one side of the movable frame 10. A rotating block 21 is rotatably installed on the top of the base 7, and a screw 19 is rotatably installed on the rotating block 21. A limit block 20 and a fixing block 22 are threadedly connected to the screw 19. A guide rail is fixedly connected to the top of the movable frame 10 by screws. A slider is fixedly connected to the bottom of the guide bracket 12 by screws, and the slider is slidably connected to the guide rail.

[0026] The working principle of this utility model is as follows: During the production process, the upper unwinding device 2 and the lower unwinding device 3 are started synchronously. At this time, the UD roll material installed on the rolls of the two unwinding devices will be uniformly laminated onto the PP substrate, realizing simultaneous operation of the two workstations and effectively improving the overall production efficiency.

[0027] When the UD roll on the unwinding device 3 runs out of material and needs to be replaced, the operator first grasps the handle on the unwinding device 3 and pulls it out smoothly. During this process, the unwinding device 3 moves horizontally outward to the outside of the frame 5 along the roller guide rails 8, which are symmetrically arranged on the left and right, with the help of four evenly distributed roller bodies 17 on the moving frame 10. Then, the crane 1 installed on the top of the fixed plate 6 is started to unload the empty roll, and the new UD roll is then reinstalled onto the roll using the crane 1. After installation, the operator pushes the unwinding device 3 back to its original position along the roller guide rails 8. The replacement of the upper unwinding device 2 can be done directly by using the crane 1. By designing a push-pull type unwinding device 3 in the empty space below the frame 5, the space is fully utilized, and the unwinding device 3 is added on the original basis. The simultaneous operation of the two workstations improves production efficiency. At the same time, the pull-out structure and the hoisting system work together to achieve a fast and labor-saving roll changing operation.

[0028] During the lamination process, if the UD belt deviates laterally, the operator only needs to turn the handwheel 15 located on the side of the UD roll that is deviating. When the handwheel 15 turns, the lead screw 13 connected to it starts to turn synchronously, thereby driving the support block 16 and the guide bracket 12 to move laterally along the guide rail. This achieves the effect of online correction during the lamination process, and can adjust the position of the UD belt in time when it deviates. After the correction adjustment is completed, it effectively avoids the deviating problem that may occur after the UD roll is installed on the crane 1 due to the lack of correction means, and ensures the stability and accuracy of the lamination process.

[0029] To further improve the composite accuracy and prevent vibration caused by the rotation of the roll material during the composite process, which could lead to deviation, a limit mechanism is also provided. After the crane 1 installs the UD roll material, when the moving frame 10 drives the unwinding device 3 to reset, the screw 19 is rotated 90 degrees so that the limit plate 18 is located between the fixed block 22 and the limit block 20. Then, the fixed block 22 and the limit block 20 are rotated respectively to clamp the limit plate 18 at the same time. Because the threaded connection has a self-locking effect, the fixed block 22 and the limit block 20 are stably locked and fixed after rotation adjustment and clamping the limit plate 18. The unwinding device 3 is fixed, which effectively avoids deviation caused by vibration and improves the composite stability.

[0030] Finally, it should be noted that the function of the preheater 4 is to guide the composite UD tape into the preheater 4, and after pre-melting by the high-temperature rollers, it is precisely and firmly composited onto the upper and lower surfaces of the PP substrate. The preheater 4 is existing technology and will not be described in detail here. The upper unwinding device 2 and the lower unwinding device 3 each consist of two stations, left and right. After the handwheel 15 is corrected, it will not deviate due to vibration because the screw 19 and the support block 16 are threaded and have a self-locking effect.

[0031] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
