Description

Technical Field

[0001] This utility model relates to the field of glass fiber conduit production technology, and in particular to a short fiber cutting device for a glass fiber conduit production line. Background Technology

[0002] The manufacturing process of glass fiber reinforced plastic (GFRP) pipes can be divided into two types: fixed-length winding and continuous winding. Fixed-length winding refers to a production method in which pipes are manufactured layer by layer from the inside to the outside within a mold of a fixed length using spiral winding and / or circumferential winding techniques. Continuous winding refers to a production method in which resin, continuous fibers, chopped fibers, and quartz sand are continuously laid in layers according to certain requirements using a circumferential winding method on a continuously output mold, and after curing, the layers are cut into pipe products of a certain length.

[0003] A chopped fiber device is a chopped fiber addition device used in glass fiber conduit (glass fiber reinforced composite material pipe) production lines. It is used to precisely cut continuous glass fiber yarn to a set length and uniformly disperse it into the resin mixing system. Existing chopped fiber devices have poor cutting effect when cutting glass fiber yarn, resulting in some glass fiber yarn not being completely cut. This is because the glass fiber yarn is fed into the chopped fiber device in bundles for cutting and is not combed or dispersed, resulting in some glass fiber yarn not being completely cut, which affects the performance. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenience in combing and dispersing glass fiber yarn in the prior art, and to propose a short fiber cutting device for a glass fiber guide production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fiber shaving device for a glass fiber guide tube production line includes two side plates mounted on the surface of a mounting frame and a slitting assembly disposed on the surfaces of the two side plates. Above the two side plates are multiple sets of guide tubes for combing glass fiber bundles. The multiple guide tubes are mounted on the surface of the slitting assembly. Each guide tube includes a lower tube body and an upper tube body. Comb teeth are fixed inside the upper tube body and the lower tube body respectively. Two comb teeth are arranged crosswise, and both comb teeth are located inside the upper tube body and the lower tube body near one end of the slitting assembly.

[0007] In some embodiments, the two comb teeth are arranged crosswise, and both comb teeth are located inside the upper tube and the lower tube near one end of the cutting assembly.

[0008] In some embodiments, a tube head is fixed to the end of the lower tube body away from the cutting assembly, the ends of the upper and lower tube bodies facing the tube head are conical, a sleeve for fastening the upper and lower tube bodies is slidably attached to the surface of the tube head, and a magnetic ring is fixed to the end of the tube head away from the upper and lower tube bodies.

[0009] In some embodiments, the separation assembly is used to simultaneously separate the upper tube and the lower tube. The separation assembly includes a fixing plate fixed to the upper surface of the side plate and a connecting plate hinged to the surface of the fixing plate. Guide plates are fixed at both ends of the fixing plate, and guide posts that cooperate with the guide plates are fixed at both ends of the connecting plate.

[0010] In some embodiments, the surfaces of the two guide plates are respectively provided with limiting components for keeping the connecting plate vertical. The limiting components include a limiting block that slides vertically on the surface of the guide plate and a spring fixed to the lower surface of the limiting block.

[0011] In some embodiments, the slitting assembly includes a secondary roller that cooperates with the slitting roller, and a conveying roller is rotatably connected between the two side plates, the conveying roller cooperating with the secondary roller.

[0012] In some embodiments, the auxiliary roller is mounted on the surfaces of two side plates via two sets of adjusting components. The adjusting components include a first mounting groove formed on the surface of the side plate and a first movable block that slides on the inner wall of the first mounting groove. A threaded post is inserted into the side of the first movable block, and the threaded post is threadedly connected to a threaded tube, which is fixed to the upper surface of the side plate.

[0013] In some embodiments, the slitting roller is fixed to the surfaces of two side plates by two sets of mounting components. The mounting components include a second movable groove formed on the surface of the side plate and a second movable block that slides on the inner wall of the second movable groove. The second movable block is pressed against the inner wall of the first mounting groove by a pressure plate.

[0014] Compared with the prior art, the present invention provides a short fiber chopped device for a glass fiber conduit production line, which has the following beneficial effects.

[0015] 1. This utility model guides the glass fiber yarn bundle by setting a guide tube, allowing it to smoothly enter between the auxiliary roller and the conveying roller. By setting a comb, the glass fiber yarn bundle is dispersed and combed, so that it is evenly dispersed between the auxiliary roller and the conveying roller. The dispersed glass fiber yarn bundle is cut by a cutting roller, which can avoid the appearance of uncut glass fibers.

[0016] 2. In this utility model, by setting a separation component, the connecting plate rotates on the surface of the fixed plate, thereby simultaneously driving multiple upper tubes to separate from the lower tubes.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Reference Figure 1-7A fiber shaving device for a glass fiber conduit production line includes two side plates 1 mounted on the surface of a mounting frame 2 and a cutting assembly 3 disposed on the surface of the two side plates 1. A discharge plate 8 for receiving glass fiber segments is disposed below the cutting assembly 3.

[0029] The slitting assembly 3 includes a secondary roller 301 that cooperates with the slitting roller 302. The surface of the slitting roller 302 is evenly provided with a plurality of slitting teeth, which are in contact with the secondary roller 301. The secondary roller 301 is a rubber roller. A conveying roller 303 is rotatably connected between the two side plates 1. The conveying roller 303 cooperates with the secondary roller 301. The slitting roller 302 is driven to rotate by a drive motor, which is fixed on the surface of the mounting frame 2.

[0030] Understandably, when glass fiber needs to be cut, it is fed between the auxiliary roller 301 and the conveying roller 303. The cutting roller 302 is driven to rotate by the drive motor, which in turn drives the auxiliary roller 301 to rotate. The auxiliary roller 301 drives the conveying roller 303 to rotate through friction, thereby feeding the glass fiber yarn between the cutting roller 302 and the auxiliary roller 301. With the cooperation of the cutting roller 302 and the auxiliary roller 301, the glass fiber yarn is cut.

[0031] Specifically, the auxiliary roller 301 is mounted on the surfaces of the two side plates 1 via two sets of adjusting components 4, and the cutting roller 302 is fixed to the surfaces of the two side plates 1 via two sets of mounting components 5. The adjusting components 4 include a first mounting groove 401 formed on the surface of the side plate 1 and a first moving block 402 that slides on the inner wall of the first mounting groove 401. The first mounting groove 401 is U-shaped, and the upper and lower surfaces of the first moving block 402 are respectively provided with grooves. The first moving block 402 slides on the inner wall of the first mounting groove 401 through the grooves. The two ends of the auxiliary roller 301 rotate on the surface of the first moving block 402 via bearings. A threaded post 404 is inserted into the side of the first moving block 402. The threaded post 404 is threadedly connected to a threaded tube 403. The threaded tube 403 is fixed to the upper surface of the side plate 1. A rotating handle is fixed to the other end of the threaded post 404. An insertion hole for inserting a threaded hole is formed on the side of the first moving block 402.

[0032] It is understandable that by setting the adjustment component 4, the auxiliary roller 301 is inserted into the inner wall of the first mounting groove 401 through the first moving block 402, and the threaded column 404 is inserted into the insertion hole on the side of the first moving block 402. The engagement of the threaded column 404 and the threaded tube 403 pushes the first moving block 402 to slide, thereby adjusting the distance between the auxiliary roller 301 and the cutting roller 302 and maintaining the cutting effect of the cutting roller 302 on the glass fiber yarn.

[0033] Specifically, the mounting component 5 includes a second movable groove formed on the surface of the side plate 1 and a second movable block 502 that slides on the inner wall of the second movable groove. The two ends of the cutting roller 302 rotate on the surface of the two second movable blocks 502 through bearings. The second movable blocks 502 are pressed against the inner wall of the first mounting groove 401 by a pressure plate 503. The pressure plate 503 is fastened to the side of the side plate 1 by two bolts.

[0034] It is understandable that by setting the slitting roller 302 to be detachable, it is easy to replace different models of slitting roller 302 for slitting glass fiber segments of different lengths. The second moving block 502 is pressed and fixed by the pressure plate 503, which facilitates the fixation of the second moving block 502 and the slitting roller 302.

[0035] Specifically, multiple sets of guide tubes 7 for combing glass fiber yarn bundles are provided above the two side plates 1. The multiple guide tubes 7 are all installed on the surface of the separation component 6. The separation component 6 is fixed on the upper surface of the two side plates 1. The guide tubes 7 are inclined, and the end away from the cutting component 3 is higher than the end close to the cutting component 3.

[0036] The guide tube 7 includes a lower tube body 701 and an upper tube body 702. Both the upper tube body 702 and the lower tube body 701 are half-circular tubes. A tube head 703 is fixed at the end of the lower tube body 701 away from the cutting component 3. Comb teeth 704 are fixed inside the upper tube body 702 and the lower tube body 701 respectively. The two comb teeth 704 are arranged crosswise. Both comb teeth 704 are located inside the upper tube body 702 and the lower tube body 701 at the end close to the cutting component 3.

[0037] It is understandable that by setting the guide tube 7, the glass fiber yarn bundle is guided to smoothly enter between the auxiliary roller 301 and the conveying roller 303. By separating the upper tube body 702 and the lower tube body 701, the glass fiber yarn bundle passes through the tube head 703 and is placed on the surface of the comb teeth 704 inside the lower tube body 701. The comb teeth 704 disperse and comb the glass fiber yarn bundle, making it evenly dispersed between the auxiliary roller 301 and the conveying roller 303. The splitting roller 302 splits the dispersed glass fiber yarn bundle, which can prevent the appearance of uncut glass fibers.

[0038] Specifically, the upper tube 702 and the lower tube 701 have a conical end facing the tube head 703. A sleeve 705 for fastening the upper tube 702 and the lower tube 701 slides on the surface of the tube head 703. A magnetic ring 706 is fixed at the end of the tube head 703 away from the upper tube 702 and the lower tube 701.

[0039] It is understandable that by setting the sleeve 705, the sleeve 705 is inserted into one end of the conical surface of the upper tube body 702 and the lower tube body 701, thereby securing one end of the guide tube 7. By setting the tube head 703, the glass fiber is prevented from being embedded in the gap between the upper tube body 702 and the lower tube body 701. By setting the magnetic ring 706, the sleeve 705 is temporarily attracted, keeping it separated from the upper tube body 702 and the lower tube body 701, which facilitates the separation of the upper tube body 702 and the lower tube body 701.

[0040] Specifically, the separation component 6 is used to simultaneously separate the upper tube 702 and the lower tube 701. The separation component 6 includes a fixing plate 601 fixed to the upper surface of the side plate 1 and a connecting plate 602 hinged to the surface of the fixing plate 601. Multiple lower tubes 701 are fixed to the surface of the fixing plate 601, and multiple upper tubes 702 are fixed to the surface of the connecting plate 602. Guide plates 603 are fixed to both ends of the fixing plate 601, and guide posts 604 are fixed to both ends of the connecting plate 602. An arc-shaped guide groove is opened on the surface of the guide plate 603, and the guide post 604 slides on the inner wall of the guide groove.

[0041] It is understandable that by rotating the connecting plate 602 on the surface of the fixed plate 601, multiple upper tubes 702 and lower tubes 701 are simultaneously separated. While the connecting plate 602 is rotating, the guide post 604 slides on the surface of the guide plate 603, and the rotation angle of the connecting plate 602 is limited by the guide groove.

[0042] Specifically, the surfaces of the two guide plates 603 are respectively provided with limiting components 605 for keeping the connecting plate 602 vertical. The limiting components 605 include a limiting block 6051 that slides vertically on the surface of the guide plate 603 and a spring 6052 that is fixed to the lower surface of the limiting block 6051. The lower end of the spring 6052 is fixed to the surface of the guide plate 603.

[0043] It is understandable that the guide post 604 is limited by the spring 6052 pushing the limit block 6051, thereby preventing the guide post 604 from sliding on the inner wall of the guide groove, thus limiting the rotation of the connecting plate 602 and keeping the upper tube 702 and the lower tube 701 in a closed state.

[0044] In this invention, by separating the sleeve 705 from the upper tube 702 and the lower tube 701, the sleeve 705 is temporarily fixed under the action of the magnetic ring 706. By releasing the limiting block 6051 from the guide post 604, the connecting plate 602 rotates on the surface of the fixing plate 601, thereby simultaneously driving multiple upper tubes 702 to separate from the lower tube 701. The glass fiber yarn bundle passes through the tube head 703 and is placed on the surface of the comb teeth 704 inside the lower tube 701. The comb teeth 704 disperse and comb the glass fiber yarn bundle, making it evenly dispersed between the auxiliary roller 301 and the conveying roller 303. Then, the upper tube 702 and the lower tube 701 are separated. 01 Close the tube and insert the sleeve 705 into one end of the conical surface of the upper tube 702 and the lower tube 701 to secure one end of the guide tube 7. Drive the cutting roller 302 to rotate through the drive motor. The cutting roller 302 drives the auxiliary roller 301 to rotate. The auxiliary roller 301 drives the conveying roller 303 to rotate through friction. Thus, the auxiliary roller 301 and the conveying roller 303 feed the glass fiber yarn between the cutting roller 302 and the auxiliary roller 301. With the cooperation of the cutting roller 302 and the auxiliary roller 301, the glass fiber yarn is cut. The cutting roller 302 cuts the dispersed glass fiber yarn bundle, which can avoid the appearance of uncut glass fibers.
