Description

Technical Field

[0001] This utility model belongs to the technical field of carbon fiber prepreg spreading structure, specifically a carbon fiber prepreg spreading structure that can prevent displacement. Background Technology

[0002] Carbon fiber prepreg, also known as carbon fiber prepreg fabric, is a composite material made from carbon fiber yarn, epoxy resin, release paper, and other materials through processes such as coating, hot pressing, cooling, lamination, and winding. It's called prepreg fabric because this is only the initial impregnation of resin and carbon fiber; the final impregnation occurs during carbon fiber molding. Carbon fiber prepreg fabric is widely used in fishing tackle, sports equipment, sporting goods, and aerospace. In the military, it can be used to manufacture important military carbon fibers for rockets, missiles, satellites, radar, bulletproof vehicles, and bulletproof vests.

[0003] A search revealed that patent CN207904446U discloses a carbon fiber prepreg spreading structure, including a concave seat with a motor cavity. A motor is fixedly installed within the motor cavity. Two grooves are symmetrically formed on the top side of the concave seat. Through holes are formed on both inner walls of the motor cavity, communicating with the grooves. A rotating shaft is rotatably installed within the through holes. One end of the rotating shaft near the motor cavity extends into the motor cavity and is fixedly connected to the motor's output shaft. The other end of the rotating shaft extends into the groove and is fixedly fitted with a first bevel gear. A sliding rod is slidably installed within the groove. A threaded groove is formed at the bottom of the sliding rod, and a rotating rod is rotatably installed within the threaded groove. The bottom end of the rotating rod extends out of the threaded groove and is fixedly fitted with a second bevel gear. The first and second bevel gears mesh. This invention allows adjustment of the combing degree of carbon fiber prepreg fabric to meet different requirements by adjusting the height of the toothed pins. It has a simple structure and is easy to operate.

[0004] During the pre-impregnation and trial unfolding of carbon fibers using the above-mentioned unfolding structure, the soaked carbon fibers are unfolded while being transported on the left-right moving conveyor cylinder. However, at the same time, the position of the carbon fibers shifts, causing the carbon fibers to shift when being wound up after soaking. Summary of the Invention

[0005] The purpose of this invention is to provide a carbon fiber prepreg spreading structure that can prevent deviation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber prepreg spreading structure with anti-deviation capability, comprising a main body, an outer frame fixedly installed at both ends of the main body, an anti-deviation mechanism fixedly installed in the interlayer between the outer frame and the main body, a boss provided on the inner wall of the main body, and a detection mechanism fixedly installed on the boss. Furthermore, the interior of the main body has multiple pairs of opposing holes, and a protective sleeve is rotatably installed on the holes inside the main body. A guide roller is fixedly installed inside the protective sleeve, and the protective sleeve is laid on the guide roller. Furthermore, a pair of opposing grooves are provided inside the main body, and a pair of guide sleeves are slidably installed on the pair of opposing grooves inside the main body, and an offset roller is fixedly installed inside the guide sleeves. Furthermore, a correction motor is fixedly installed at one end of the outer frame near the main body, and a transmission gear is fixedly installed at the output end of the correction motor. A connecting rod is fixedly installed on one end of the guide sleeve facing the outer frame, and a rotating rod is rotatably installed on the end of the connecting rod away from the guide sleeve. A fixed gear is fixedly installed on the end of the rotating rod away from the transmission gear, and the fixed gear meshes with the transmission gear. Furthermore, the testing mechanism includes a laser emitter, which is fixedly mounted on a boss of the main body away from the correction motor, and a laser receiver is fixedly mounted on a boss of the main body near the correction motor, with the laser receiver positioned opposite to the laser emitter. Furthermore, the anti-deviation mechanism includes a guide plate, which is fixedly installed inside the upper part of the main body.

[0007] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses laser detection to detect moving carbon fibers. When the carbon fiber deviates, it will block the laser receiver on that side, so that the laser emitted by the laser emitter on that side cannot be transmitted to the corresponding laser detector. 2. After the laser detection mechanism detects the carbon fiber offset, the motor on this side will drive the gear transmission to the linkage mechanism fixed on the transmission gear to push the offset roller to correct the offset part of the carbon fiber.

Detailed Implementation

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Please see Figure 1 A carbon fiber prepreg spreading structure with anti-deviation capability includes a main body 102, with an outer frame 101 fixedly installed at both ends of the main body 102. An anti-deviation mechanism 2 is fixedly installed in the interlayer between the outer frame 101 and the main body 102 to correct the deviation of the carbon fiber 1. A boss is provided on the inner wall of the main body 102, and a detection mechanism 3 is fixedly installed on the boss. The detection mechanism 3 is used to detect whether the moving carbon fiber 1 has deviated. When the detection mechanism 3 detects that the carbon fiber 1 has deviated, the anti-deviation mechanism 2 is activated to correct the deviated part.

[0012] Please see Figure 2 The main body 102 has multiple pairs of opposing holes inside. A protective sleeve 104 is rotatably installed on the holes inside the main body 102. A guide roller 103 is fixedly installed inside the protective sleeve 104. The protective sleeve 104 is laid on the guide roller 103. The inner layer of the main body 102 has three pairs of circular holes. The protective sleeve 104 is fixedly installed on the three pairs of circular holes. A guide roller 103 is rotatably installed on two opposing protective sleeves 104. When the carbon fiber 1 enters this process, it will continue to move forward under the guidance of the guide roller 103.

[0013] Please see Figure 3 The main body 102 has a pair of opposing grooves inside, and a pair of guide sleeves 202 are slidably installed on the pair of opposing grooves inside the main body 102. An offset roller 201 is fixedly installed inside the guide sleeves 202. The inner layer of the main body 102 has a pair of opposing grooves, and the guide sleeves 202 are slidably installed on the grooves. An offset roller 201 is fixedly installed on the pair of opposing guide sleeves 202. When the carbon fiber 1 is offset, the guide sleeves 202 will drive the offset roller 201 to move outward along the groove to correct the offset carbon fiber 1.

[0014] Please see Figures 1-4 A correction motor 203 is fixedly installed at one end of the outer frame 101 near the main body 102. A transmission gear 204 is fixedly installed at the output end of the correction motor 203. A connecting rod 207 is fixedly installed on one end of the guide sleeve 202 facing the outer frame 101. A rotating rod 206 is rotatably installed on the end of the connecting rod 207 away from the guide sleeve 202. A fixed gear 205 is fixedly installed on the end of the rotating rod 206 away from the transmission gear 204. The fixed gear 205 and the transmission gear 204 mesh with each other. When the carbon fiber 1 is deviated, the output of the correction motor 203 will drive the transmission gear 204 to rotate. The transmission gear 204 meshes with the fixed gear 205, so that when the transmission gear 204 rotates, it will drive the fixed gear 205. The rotating rod 206 and the connecting rod 207 form the simplest connecting rod structure. When the fixed gear 205 rotates, it will drive the rotating rod 206 to rotate. The rotation of the rotating rod 206 will drive the connecting rod 207 to reciprocate, thereby pushing the offset roller 201 and the guide sleeve 202.

[0015] Please see Figure 5 The detection mechanism 3 includes a laser emitter 301, which is fixedly installed on a boss of the main body 102 away from the correction motor 203. A laser receiver 302 is fixedly installed on the boss of the main body 102 near the correction motor 203, and the laser receiver 302 is arranged opposite to the laser emitter 301. Opposite laser emitters 301 and laser receivers 302 are installed on both sides inside the main body 102. The laser emitter 301 emits laser light to the laser receiver 302. When the carbon fiber 1 is deviated, it will block the laser light from the laser emitter 301 on one side. When the laser receiver 302 on one side does not detect the laser light, the correction motor 203 on that side will work to correct the deviation of the carbon fiber 1.

[0016] Please see Figure 5 The anti-deviation mechanism 2 includes a guide plate 208, which is fixedly installed inside the upper part of the main body 102. Two guide rods are provided at the upper end of the guide plate 208. The guide rods are V-shaped and gradually narrow from the inside to the outside. When the carbon fiber 1 above moves to the guide plate 208 after deviation correction, if part of the carbon fiber 1 is deviated, the deviated part of the carbon fiber 1 will contact the guide rods on both sides, and the guide rods will guide the deviated part of the carbon fiber 1 to the normal position.

[0017] Working principle: The detection mechanism 3 detects whether the moving carbon fiber 1 has deviated. When the deviated part of the carbon fiber 1 blocks the laser emitted by the laser emitter 301, the laser receiver 302 cannot receive the laser emitted by the laser emitter 301, and the correction motor 203 on that side will rotate. When the transmission gear 204 on the output end of the correction motor 203 rotates 180°, the correction motor 203 stops rotating, causing the deviated roller 201 on that side to be pushed out to correct the deviated part. When the laser receiver 302 receives the laser emitted by the laser emitter 301 again, the correction motor 203 rotates again. When the transmission gear 204 on the output end of the correction motor 203 rotates 180° again, the correction motor 203 stops rotating, causing the deviated roller 201 on that side to be retracted.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope of the technology disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
