Description

Technical Field

[0001] The utility model relates to the technical field of prepreg yarn threading, in particular to a prepreg rapid yarn threading driving device. Background Art

[0002] Before prepreg production, the yarn needs to be arranged from the yarn rack through yarn arranging and yarn spreading to the first set of pressing units according to specifications; during intermediate yarn threading, it needs to pass through numerous holes, as well as carding combs and yarn spreading guide rollers, etc.

[0003] In the prior art, after an operator threads one by one yarns through the yarn collecting plate and all carding combs, generally, a high-temperature tape with high viscosity is pasted on the front of the whole row of yarns. After the tape is bent, it is pasted on the back of the yarns to form a row of yarns. However, this row of yarns is very soft because it is bonded with tape, and it requires multiple people to hold these bonded yarns to draw the yarns forward. As the yarns are pulled tighter and tighter, the tension of multiple yarns is large, and it is very laborious to pull only by hand. At this time, it is necessary for an operator to press the yarns loose from top to bottom between the yarn collecting plate and the yarn arranging device, and then thread the yarns. After repeating many times, the yarns are threaded to the first set of pressing units. The operation process is cumbersome and laborious, requires multiple people to cooperate in threading the yarns, and has high requirements for the operation skills of the operator, resulting in low yarn threading efficiency. Therefore, we propose the present utility model. Content of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a prepreg rapid yarn threading driving device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A prepreg rapid yarn threading driving device includes a support frame. A yarn threading structure is arranged on one side of the support frame, and a yarn pressing structure is arranged inside the support frame. The yarn threading structure includes a yarn clamping frame arranged on one side of the support frame. A waist groove is formed on one side of the yarn clamping frame, and a plurality of clamping grooves are formed on the top surface of the yarn clamping frame. The plurality of clamping grooves are uniformly distributed along the length direction of the yarn clamping frame. A plurality of yarns are slidably inserted into the waist groove, and the plurality of yarns are respectively slidably inserted into the plurality of clamping grooves.

[0007] As a further scheme of the utility model, the yarn pressing structure includes two air cylinders fixed inside the support frame. A pressing roller is arranged below the air cylinders. Guide rails are fixed on both sides of the inner wall of the support frame, and the sliders of the two guide rails are respectively fixed to both ends of the pressing roller.

[0008] As a further scheme of the utility model, a support guide rod is fixed inside the support frame. The support guide rod is located below the pressing roller and is arranged parallel to the pressing roller.

[0009] As a further solution of the present utility model, a hanging plate is fixed on one side of the support frame, and a cutting knife is detachably clamped inside the hanging plate. The cutting knife is composed of a cutting knife handle and an electric heating blade.

[0010] As a further solution of the present utility model, two hooks are fixed on one side of the support frame. The two hooks are arranged in parallel, and the handles at both ends of the yarn clamping frame are respectively slidably inserted into the two hooks.

[0011] As a further solution of the present utility model, the two cylinders are arranged in parallel, and the telescopic ends of the two cylinders are respectively fixed to the top surfaces of the sliders of the two guide rails.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] For this yarn threading and starting device, through the arrangement of the yarn threading structure and the yarn pressing structure, the staff first passes the yarn through the waist groove, then clips it in the clamping groove on the top surface of the yarn clamping frame, pastes both sides of the yarn with tape, holds the handles on both sides of the yarn clamping frame, and drives the yarn to thread quickly. During the yarn threading process, the yarn passes through the inside of the support frame and is located below the pressing roller. When the tension increases due to multiple yarns threading together, the staff starts the cylinder. The cylinder extends to push the slider of the guide rail, driving the pressing roller to press down on the yarn. After pressing on the yarn, the cylinder immediately retracts, and the pressing roller returns to its original position. The cylinder drives the pressing roller to reciprocate to push the yarn, so that the yarn relaxes to facilitate yarn threading. Through the above method, it is convenient for workers to thread yarn, improves the yarn threading efficiency of workers, and reduces labor. Description of the Drawings

A yarn threading structure is provided on one side of the support frame 1, and a yarn pressing structure is provided inside the support frame 1. The yarn threading structure includes a yarn clamping frame 2 provided on one side of the support frame 1. A waist groove 202 is formed on one side of the yarn clamping frame 2, and a plurality of clamping grooves 203 are formed on the top surface of the yarn clamping frame 2. The plurality of clamping grooves 203 are evenly distributed along the length direction of the yarn clamping frame 2. A plurality of yarns 201 are slidably inserted into the waist groove 202, and the plurality of yarns 201 are respectively slidably inserted into the plurality of clamping grooves 203.

[0023] In this embodiment, the yarn pressing structure includes two cylinders 3 fixed inside the support frame 1, a pressing roller 301 is arranged below the cylinder 3, guide rails 302 are fixed on both sides of the inner wall of the support frame 1, and the sliders of the two guide rails 302 are respectively fixed to the two ends of the pressing roller 301. Through the setting of the yarn threading structure and the yarn pressing structure, the staff first passes the yarn 201 through the waist groove 202, and then clamps it in the clamping groove 203 on the top surface of the yarn clamping frame 2, sticks the two sides of the yarn 201 with tape, grabs the handles on both sides of the yarn clamping frame 2, and drives the yarn 201 to thread the yarn quickly. During the threading process, the yarn 201 passes through the interior of the support frame 1 and is located below the pressing roller 301. When the yarn 201 is threaded together and the tension increases, the staff starts the cylinder 3, and the cylinder 3 extends out to push the slider of the guide rail 302, driving the pressure roller 301 to press the yarn 201 downward. After pressing the yarn 201, the cylinder 3 retracts immediately, and the pressure roller 301 returns to its original position. The cylinder 3 drives the pressure roller 301 to move back and forth to push the yarn 201, so that the yarn 201 relaxes to facilitate threading. The movement of the pressure roller 301 can be controlled by the cylinder 3 or the motor. The device preferably uses the cylinder 3 for control, and the whole process is automatically controlled by the program. In the above manner, it is convenient for workers to thread the yarn, improves the workers' threading efficiency, and reduces labor.

[0024] In this embodiment, a support guide rod 5 is fixed inside the support frame 1. The support guide rod 5 is located below the pressure roller 301. The support guide rod 5 is arranged parallel to the pressure roller 301. When the yarn pressing structure presses the yarn 201, the support guide rod 5 protects the yarn 201 from being too long and falling to the ground.

[0025] In this embodiment, a hanging plate 4 is fixed to one side of the support frame 1, and a cutter 401 is detachably connected to the interior of the hanging plate 4. The cutter 401 consists of a cutter handle and an electric heating blade. In the prepreg production line, after the yarn 201 is pulled to the first group of impregnation and lamination units, the film needs to be introduced. The staff quickly pulls the film protected by the PE film into the impregnation and lamination unit first, and then cuts the PE film on the surface of the film by the cutter 401 without cutting the release paper. Then, the PE film is peeled off here and rolled up to avoid the resin on the surface of the film sticking to the guide roller due to the relaxation of the film after the PE film is peeled off from the film unwinding position.

[0026] In this embodiment, two hooks 6 are fixed to one side of the support frame 1, and the two hooks 6 are arranged in parallel. The handles at both ends of the yarn clamping frame 2 are slidably inserted into the inside of the two hooks 6, and the yarn clamping frame 2 can be stably placed through the hooks 6.

[0027] In this embodiment, the two cylinders 3 are arranged in parallel, and the telescopic ends of the two cylinders 3 are respectively fixed to the top surfaces of the sliders of the two guide rails 302. The two cylinders 3 arranged in parallel can be synchronously telescoped at both ends of the pressure roller 301 through the sliders of the guide rails 302, so that the pressure roller 301 is more stable when moving.

[0028] Working principle: In use, the staff first passes the yarn 201 through the waist groove 202, and then clamps it in the clamping groove 203 on the top surface of the yarn clamping frame 2, sticks the two sides of the yarn 201 with tape, grabs the handles on both sides of the yarn clamping frame 2, and drives the yarn 201 to thread the yarn quickly. During the threading process, the yarn 201 passes through the interior of the support frame 1 and is located below the pressure roller 301. When multiple yarns 201 are threaded together and the tension increases, the staff starts the cylinder 3, and the cylinder 3 extends the slider that pushes the guide rail 302, driving the pressure roller 301 to push the yarn 201 downward. After pushing the yarn 201, the cylinder 3 retracts immediately, and the pressure roller 301 returns to its original position. The cylinder 3 drives the pressure roller 301 to reciprocate and push the yarn 201, so that the yarn 201 relaxes to facilitate threading. When the yarn pressing structure pushes the yarn 2 01 When the yarn is pressed, the support guide rod 5 is protected under the yarn 201 to prevent the yarn 201 from being too long and falling to the ground. In the prepreg production line, after the yarn 201 is pulled to the first group of impregnation and pressing units, the film needs to be introduced. The staff quickly pulls the film protected by the PE film into the impregnation and pressing unit, and then cuts the PE film on the surface of the film by the cutter 401 without cutting the release paper. Then, the PE film is peeled off here and rolled up to avoid the resin on the surface of the film sticking to the guide roller due to the relaxation of the film after the PE film is peeled off from the film unwinding position. The yarn clamping frame 2 can be stably placed by the hook 6, and the two parallel cylinders 3 can be synchronously extended and retracted at both ends of the pressing roller 301 through the slider of the guide rail 302, so that the pressing roller 301 is more stable when moving.
