Description
Technical Field
[0001] This invention relates to the field of hot press tube rolling machines, specifically to a fabric insert mold core structure for a fully automatic hot press tube rolling machine. Background Technology
[0002] In the field of composite material tube production, fully automatic hot press tube rolling machines have been widely used in the molding and processing of various composite tubes such as fiberglass and carbon fiber due to their high efficiency and stable rolling advantages. The core working principle is to soften the impregnated cloth and melt the resin by heating with hot rollers. Under a certain tension, the impregnated cloth is continuously rolled onto the surface of the mold core through the friction between the mold core and the roller. After cooling, shaping and curing, the required tubular component is formed. As the core load-bearing component in the tube rolling process, the connection stability between the mold core and the cloth end directly determines the efficiency, continuity and quality of the tube rolling process. Currently, existing fully automatic hot-press tube rolling machines have not yet achieved automated connection between the fabric end and the mold core in the initial stage of tube rolling. The connection between the fabric end and the mold core still needs to be completed manually before the subsequent automatic tube rolling process can be started. Specifically, the operator must first position the end of the fabric to be rolled onto the surface of the mold core, and then fix the fabric end to the mold core by manual pasting. Only after confirming that the connection is in place can the tube rolling machine be started for subsequent continuous rolling operations. This operation mode has significant technical defects. On the one hand, the manual connection of the fabric end and the mold core is a cumbersome process that requires additional labor costs and is inefficient. It cannot meet the high-speed continuous production requirements of the fully automatic hot press tube rolling machine, which seriously restricts the improvement of the overall production cycle and goes against the development trend of automated production. Especially in batch production scenarios, the manual pasting of the fabric end is repeated in the initial stage of rolling each tube, which takes a long time and greatly reduces production efficiency. On the other hand, the manual pasting method has the problem of insufficient connection strength. Due to the difference in the operation standards of the operators, it is difficult to ensure the adhesion and firmness of the cloth end to the mold core surface during the pasting process. In addition, during the pipe rolling process, the impregnated cloth is subjected to continuous tension, and the tension fluctuates with the increase of the pipe thickness and slight changes in the equipment operation status. When the tension fluctuates or increases instantaneously, the manually pasted cloth end is very likely to fall off, causing the pipe rolling work to be interrupted. This not only requires the operators to re-connect the cloth end, further reducing production efficiency, but may also cause problems such as wrinkles and interlayer misalignment of the impregnated cloth due to the cloth end falling off, affecting the wall thickness uniformity and structural strength of the finished pipe, increasing production losses and defect rate. Furthermore, in traditional tube rolling processes, a release agent is usually applied to the surface of the mold core for subsequent demolding. This further reduces the adhesion between the fabric end and the mold core surface, significantly increasing the probability of the fabric end falling off and exacerbating the impact of the aforementioned technical defects. At the same time, the existing mold core structure does not have a dedicated fabric end positioning and connecting mechanism, making it impossible to achieve rapid and stable positioning of the fabric end, further highlighting the limitations of the traditional mold core structure in adapting to the production needs of fully automatic hot-press tube rolling machines.
[0003] In summary, the existing fully automatic hot-press tube rolling machines suffer from problems such as reliance on manual connection between the fabric end and the mold core, low operating efficiency, insufficient connection strength, and susceptibility to fabric detachment due to tension changes. These issues severely impact the continuity, efficiency, and product quality of tube rolling production, failing to meet the high-efficiency and stable requirements of modern automated tube rolling production. Therefore, developing a fabric insertion mold core structure that can overcome these technical deficiencies and achieve automatic and stable connection between the fabric end and the mold core has become an urgent technical problem for those skilled in the art.

[0010] Furthermore, the tube winding mechanism includes an upper support plate, a lower support frame is provided below the upper support plate, the lower support frame is fixedly installed inside the tube winding machine housing, a plurality of lifting support frames are fixedly connected between the upper support plate and the lower support frame, a movable seat plate is provided between the upper support plate and the lower support frame, the movable seat plate is slidably installed on the lifting support frame, an upper pressure cylinder is fixedly installed on the upper support plate, and the telescopic end of the upper pressure cylinder is fixedly connected to the movable seat plate.

It eliminates the need for workers to manually connect the fabric to the winding mold core at the beginning of winding, thereby improving the processing efficiency of the device and making it more adaptable.

Detailed Implementation
[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] Please see Figure 1-10 The present invention provides a technical solution for a fabric inserting mold core structure for a fully automatic hot-pressing tube rolling machine: including a tube rolling machine housing 1, a tube rolling mechanism 2 for tube rolling is installed inside the tube rolling machine housing 1, a fabric pulling mechanism 3 is provided on one side of the tube rolling mechanism 2, and a fabric inserting mechanism 4 is provided on the side of the tube rolling mechanism 2 away from the fabric pulling mechanism 3.
[0019] In actual use, the device is equipped with a fabric feeding mechanism. The fabric roll is fed to the position of the winding mechanism 2 via the fabric feeding mechanism. At this time, the fabric pulling mechanism 3 will first receive the fabric fed by the fabric feeding mechanism and then connect it to the winding mechanism 2. The fabric insertion mechanism 4 is used to reinforce the connection between the fabric and the winding mechanism 2, so as to automatically connect the fabric without the need for manual connection by workers, thereby improving production efficiency.
[0020] The tube winding mechanism 2 includes an upper support plate 21, a lower support frame 22 below the upper support plate 21, and the lower support frame 22 is fixedly installed inside the tube winding machine housing 1. Multiple lifting support frames 211 are fixedly connected between the upper support plate 21 and the lower support frame 22. A movable seat plate 23 is provided between the upper support plate 21 and the lower support frame 22, and the movable seat plate 23 is slidably mounted on the lifting support frames 211. An upper pressure cylinder 212 is fixedly installed on the upper support plate 21, and the telescopic end of the upper pressure cylinder 212 is fixedly connected to the movable seat plate 23. An upper pressure roller is rotatably installed below the movable seat plate 23. 231. Two mutually symmetrical support rollers 221 are rotatably mounted on the lower support frame 22. A mold core support 24 is provided between the two support rollers 221. The mold core support 24 is slidably mounted on the lower support frame 22. The mold core support 24 has two Y-shaped brackets. A tube rolling mold core 25 is provided above the two support rollers 221. The tube rolling mold core 25 is placed on the Y-shaped brackets. A mold core lifting cylinder 241 is provided below the mold core support 24. The mold core lifting cylinder 241 is fixedly installed inside the tube rolling machine housing 1. The telescopic end of the mold core lifting cylinder 241 is fixedly connected to the mold core support 24.
[0021] The fabric feeding mechanism will feed the fabric between the roll tube mold core 25 and the support roller 221. At this time, the fabric pulling mechanism 3 will work close to the roll tube mold core 25 to pick up the fabric end. Then, the fabric pulling mechanism 3 will move slightly away from the roll tube mold core support 24 and pull up a part of the fabric. After waiting for the pulling to be completed, the roll tube mold core 25 will be placed on the mold core support 24. The fabric pulling mechanism 3 will release the fabric and then rise slightly. The mold core lifting cylinder 241 will drive the mold core support 24 and the roll tube mold core 25 to descend. Because there is a gap between the two support rollers 221 and the diameter of the roll tube mold core 25 is smaller than that of the support rollers 221, the fabric will cause the side of the fabric close to the fabric pulling mechanism 3 to curl up under the pressure of the roll tube mold core 25. At this time, the fabric pulling mechanism 3 will push the fabric to wrap around the roll tube mold core 25 half a turn. The inserting mechanism 4 takes the fabric head pushed by the pulling mechanism 3, and then the pulling mechanism 3 resets. At this time, the inserting mechanism 4 moves slightly away from the winding tube mold core 25. After the inserting mechanism 4 moves slightly away from the winding tube mold core 25, it inserts the fabric head into the gap between the winding tube mold core 25 and the support roller 221. The upper pressure cylinder 212 drives the upper pressure roller 231 to descend and press the fabric onto the winding tube mold core 25. At this time, the fabric head is pressed onto the winding tube mold core 25 by the upper pressure roller 231, so that the fabric automatically wraps around the surface of the winding tube mold core 25 to form a tight wrap. The winding tube mold core 25 is connected to the external drive device to perform the winding tube operation. When the winding tube is being stabilized, the inserting mechanism 4 will also reset. It achieves a fully automated closed-loop operation of fabric insertion, winding, and pressing. During the initial tube winding process, there is no need for manual connection of the fabric end to the tube winding die core 25, which greatly shortens the die change time. Furthermore, the upper pressure roller 231 and the support roller 221 press and guide the fabric on the surface of the tube winding die core 25, which makes the formed tube more compact during the tube winding process. Moreover, when changing the specifications of the tube winding die core 25 for different tube winding requirements, the upper pressure roller 231 and the support roller 221 can still cooperate with the tube winding die core 25 of different diameters to achieve adaptive pressing and guiding, ensuring consistent winding accuracy for various tube diameters.
[0022] The fabric spreading mechanism 3 includes a fabric spreading bracket 31, a fabric spreading lifting bracket 32 is provided on one side of the fabric spreading bracket 31, and a fabric spreading advance and retreat bracket 33 is provided below the fabric spreading lifting bracket 32. A reverse fabric folding scraper 34 for folding fabric is fixedly installed on the side of the fabric spreading advance and retreat bracket 33 near the roll tube mechanism 2. The front end of the reverse fabric folding scraper 34 is bent and the bending angle is an obtuse angle.
[0023] When the fabric end is pressed down by the roll core 25 and causes it to curl up, the reverse folding cloth scraper 34 is driven to rise until the lowest end of the reverse folding cloth scraper 34 is above the roll core 25. At this time, the reverse folding cloth scraper 34 is driven to approach the roll core 25, and the fabric end will be pushed by the reverse folding cloth scraper 34 to wrap around the roll core 25 half a turn. The bending is to better drive the fabric to wrap around the roll core 25, and it can also adapt to roll cores 25 of different sizes to prevent interference between machine parts.
[0024] Multiple evenly distributed support plates 35 are fixedly installed on the fabric feeding bracket 33. Fabric feeding claws 351 are rotatably installed on the support plates 35. The fabric feeding claws 351 are located above the reverse folding fabric scraper 34. A claw cylinder 352 is fixedly installed on the upper surface of the support plate 35. The telescopic end of the claw cylinder 352 is rotatably connected to the fabric feeding claw 351.
[0025] When the fabric is fed into the space between the support roller 221 and the upper pressure roller 231 by the fabric feeding mechanism, the gripper cylinder 352 retracts and pulls the fabric gripper 351 to rotate around the support plate 35, thereby creating a gap between the fabric gripper 351 and the reverse folding fabric scraper 34. The fabric feeding mechanism 3 moves closer to the fabric head. After the fabric head enters the gap, the gripper cylinder 352 resets and pushes the fabric gripper 351 to rotate in the opposite direction, so that the fabric gripper 351 quickly closes and clamps the fabric head. A fabric lifting module 321 for lifting is fixedly connected between the fabric support bracket 31 and the fabric lifting bracket 32. The fabric support bracket 31 is fixedly installed inside the housing 1 of the rolling machine. A first forward and backward slide rail 331 is fixedly installed on the fabric forward and backward support bracket 33. The first forward and backward slide rail 331 is slidably connected to the fabric lifting bracket 32. A fabric forward and backward electric cylinder 36 is fixedly installed on the fabric lifting bracket 32. The telescopic end of the fabric forward and backward electric cylinder 36 is fixedly installed on the fabric forward and backward support bracket 33. The fabric support bracket 31 and the fabric insertion fixing bracket 41 are both fixedly installed inside the housing 1 of the rolling machine.
[0026] The fabric lifting module 321 can drive the fabric support 31 to move vertically, thereby precisely adjusting the relative height between the reverse fabric scraper 34 and the winding tube mold core 25, ensuring that the fabric head is always in the optimal winding starting position; the sliding cooperation between the first forward and backward slide rail 331 and the fabric lifting support 32 further enhances the motion stability and avoids positioning deviation due to vibration or load changes; the fabric forward and backward electric cylinder 36 is used to push the fabric forward and backward support 33 to move horizontally, thereby adjusting the axial distance between the reverse fabric scraper 34 and the winding tube mold core 25, ensuring that fabrics of different thicknesses can be effectively bent by the reverse fabric scraper 34 and guided into the surface of the winding tube mold core 25 at the beginning of the winding stage; the fabric forward and backward electric cylinder 36 is servo driven.
[0027] The fabric insertion mechanism 4 includes a fabric insertion fixing bracket 41. A fabric insertion lifting bracket 43 is provided on one side of the fabric insertion fixing bracket 41. A fabric insertion advance and retreat bracket 431 is provided below the fabric insertion lifting bracket 43. A cutting blade shaft 44 is rotatably installed on the side of the fabric insertion advance and retreat bracket 431 near the rolling tube mechanism 2. A rotating cutting blade 45 for inserting fabric is fixedly installed on the cutting blade shaft 44.
[0028] When in use, the rotating insert 45 can rotate and adjust its angle to face different specifications of the roll tube mold core 25, and can also insert the fabric into the gap between the roll tube mold core 25 and the support roller 221. The rotating insert 45 is set at an angle, which makes it easy to receive the fabric head pushed by the reverse folding fabric scraper 34 and push it into the gap. After insertion into the gap, the insert shaft 44 does not immediately retract. When the external drive device drives the roll tube mold core 25 to rotate and roll in the fabric head, the insert shaft 44 is reset synchronously.
[0029] A rotary electric cylinder 47 for inserting a blade is fixedly installed on the inserting blade advance and retreat bracket 431. A drive arm 433 is fixedly installed on the telescopic end of the rotary electric cylinder 47. A connecting arm 434 is rotatably installed on the drive arm 433. A fixed arm 451 is fixedly installed on the rotary inserting blade 45. The end of the connecting arm 434 away from the drive arm 433 is rotatably installed on the fixed arm 451.
[0030] When different specifications of tube winding work are required, first replace the corresponding tube winding core 25. Then, the insert knife rotary electric cylinder 47 will drive the drive arm 433 to move. The movement of the drive arm 433 will drive one end of the connecting arm 434 to move, while the other end of the connecting arm 434 will be rotatably connected to the fixed arm 451. The rotating insert knife 45 is rotatably mounted on the fabric insertion bracket 431. Therefore, the rotating insert knife 45 will be driven to rotate to change the angle at which the rotating insert knife 45 is inserted between the tube winding core 25 and the support roller 221, adapting to different sizes of tube winding cores 25. This ensures that the fabric end can slide into the gap at the optimal entry angle under any tube diameter without jamming, skewing, or slipping.
[0031] A fabric insertion fixing bracket 41 and a fabric insertion lifting bracket 43 are fixedly connected to a fabric insertion lifting module 42 for lifting. A second forward and backward slide rail 432 is fixedly installed on the fabric insertion forward and backward bracket 431. The second forward and backward slide rail 432 is slidably installed on the fabric insertion lifting bracket 43. A fabric insertion forward and backward electric cylinder 46 is fixedly installed on the fabric insertion lifting bracket 43. The drive end of the fabric insertion forward and backward electric cylinder 46 is fixedly installed on the fabric insertion forward and backward bracket 431.
[0032] The fabric insertion lifting module 42 drives the fabric insertion lifting bracket 43 to rise and fall vertically, adjusting the relative height between the rotating inserter 45 and the winding tube core 25. This allows the rotating inserter 45 to more accurately take the fabric head and insert it into the gap. Meanwhile, the fabric insertion advance and retraction electric cylinder 46 can drive the fabric insertion advance and retraction bracket 431 and the rotating inserter 45 to move horizontally, thereby fine-tuning the fabric head insertion depth and ensuring that it is reliably constrained by the clamping force of the support roller 221 in the initial stage of winding. The fabric insertion advance and retraction electric cylinder 46 is also servo driven, giving the fabric insertion action precision, smoothness, and adaptability.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
