Glass fiber cloth generally needs to be specially produced and processed by rapier loom. The automatic feeding mechanism of glass fiber loom is to automatically supply glass fiber yarn or glass fiber cloth to the loom for weaving. The automatic feeding mechanism can provide appropriate yarn or cloth according to the needs of the weaving process.

[0003] The existing automatic feeding mechanism of weaving machine generally directly drives the cloth to be conveyed. In the whole conveying process, dust is easily adhered to the two sides of the cloth. The common dust removal method directly uses a dust collection device to perform negative pressure dust collection on the surface of the cloth. However, a lot of dust adhered to the cloth is difficult to be completely sucked away. Therefore, the utility model provides a weaving machine automatic feeding mechanism capable of preventing glass fiber from adhering dust. UTILITY MODEL CONTENTS

[0004] The utility model aims to provide a weaving machine automatic feeding mechanism capable of preventing glass fiber from adhering dust to solve the problems raised in the above background.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a weaving machine automatic feeding mechanism capable of preventing glass fiber from adhering dust, comprising a protective box, a lower conveying roller and an upper conveying roller,

[0006] The lower edge of one side of the protective box and the upper edge of the other side of the protective box are both provided with two groups of material guiding rollers, and the box shells near the two sides of the material guiding rollers are designed to be detachable. The inside of the protective box is connected with the lower conveying roller and the upper conveying roller through a bearing. The outside of the protective box is provided with a motor which is connected with the center shafts of the lower conveying roller and the upper conveying roller. The inside of the protective box is provided with glass fiber cloth which is wound around the material guiding rollers, the lower conveying roller and the upper conveying roller. The ends of the lower conveying roller and the upper conveying roller away from the motor are both provided with drive gears. The inside of the protective box is also provided with a blowing mechanism and a dust collection mechanism. The blowing mechanism comprises two groups of driven gears which are movably connected to the outside of the protective box. The outside of the driven gear is fixed with a limiting column. The dust collection mechanism comprises two groups of fixed pipes which are installed on the upper and lower sides of the inner wall of the protective box. One end of the fixed pipe is rotatably connected with a movable pipe through a rotating shaft. The movable pipe and the fixed pipe are connected with a hose. One side of the movable pipe and the fixed pipe is connected with a dust collection nozzle.

[0007] Preferably, the fiberglass cloth is arranged in a Z-shape on the guide roller, the lower conveyor roller, and the upper conveyor roller; the fiberglass cloth is horizontally distributed on both sides of the protective box; and the fiberglass cloth is vertically distributed between the lower conveyor roller and the upper conveyor roller.

[0008] Preferably, two sets of blowpipes are provided on both sides of the vertical side of the glass fiber cloth, and the surface of the blowpipes is provided with several nozzles.

[0009] Preferably, the two ends of the blow pipe are connected and fixed with turntables, and the turntables are hollow structures. One of the turntables is fixed coaxially with the central axis of the driven gear, and the center of the other turntable is provided with a rotary joint, and the rotary joint is connected to an air pump through an air pipe.

[0010] Preferably, a traction arm is sleeved on the outer side of the limiting post, and a pull rod is connected to the end of the traction arm away from the limiting post.

[0011] Preferably, the pull rod is fixed to one end of the movable tube, and the two sets of fixed tubes are connected to a dust collector through a dust suction pipe, and an induced draft fan is installed on the dust collector.

[0012] Preferably, the protective box has an arc-shaped adjustment groove on its surface near the traction arm, the central axis of the adjustment groove coincides with the central axis of the rotating shaft between the movable tube and the fixed tube, and the pull rod is connected through the adjustment groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This automatic feeding mechanism for a weaving machine that can prevent dust from adhering to glass fibers is equipped with a blowing mechanism and a dust collection mechanism linked together. When the lower and upper conveying rollers rotate, they can drive the two sets of turntables and blowing pipes to rotate in the opposite direction of the tangential direction of rotation of the glass fiber cloth to the direction of movement of the glass fiber cloth. Therefore, the two sets of blowing mechanisms can spray pressurized gas onto the vertical side of the glass fiber cloth to blow away the dust on the glass fiber cloth. Furthermore, the dust raised inside the protective box is absorbed and filtered by the dust collection mechanism, thereby enabling the automatic feeding mechanism for the weaving machine to efficiently remove dust adhering to the glass fiber cloth.

[0014] 1. This automatic feeding mechanism for a weaving machine, which prevents dust from adhering to fiberglass, uses the rotation of the lower and upper conveyor rollers to drive the drive gear and driven gear to mesh. This causes the limit post to revolve around the central axis of the driven gear, which in turn pushes and pulls the traction arm. The pull rod at one end of the traction arm drives the movable tube at one end of the fixed tube to revolve around the rotating shaft. When the induced draft fan is started, it creates negative pressure inside the dust collector, causing the dust suction nozzles on the movable tube and fixed tube to absorb the dust raised inside the protective box. The dust is then filtered by the dust collector, thus enabling the automatic feeding mechanism for the weaving machine to efficiently remove dust adhering to the fiberglass cloth.

[0015] 2. This automatic feeding mechanism for a weaving machine, which prevents dust from adhering to the fiberglass, can drive two sets of turntables and blowpipes to rotate in opposite directions when the lower and upper conveyor rollers rotate. At the same time, the rotational tangent direction of the turntables and blowpipes near the vertical side of the fiberglass cloth is opposite to the movement direction of the vertical side of the fiberglass cloth. Therefore, the two sets of blowpipes drive several nozzles to spray pressurized gas onto the vertical side of the fiberglass cloth, thereby blowing away the dust adhering to the fiberglass cloth.

[0023] 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.

[0024] Please see Figures 1-6This utility model provides a technical solution: an automatic feeding mechanism for a weaving machine that can prevent dust from adhering to glass fibers, including a protective box 1, a lower conveyor roller 3, and an upper conveyor roller 4. Two sets of guide rollers 2 are installed on the lower edge of one side and the upper edge of the other side of the protective box 1. The box shell of the protective box 1 near the guide rollers 2 is detachable, facilitating the pre-passing of the fabric's starting end through the protective box 1 and also facilitating maintenance of the interior of the protective box 1. The lower conveyor roller 3 and the upper conveyor roller 4 are connected inside the protective box 1 via bearings. A motor 5, which is connected to the central axis of the lower conveyor roller 3 and the upper conveyor roller 4, is installed on the outside of the protective box 1. The interior of the protective box 1 is equipped with a winding guide roller. The glass fiber cloth 6 of roller 2, lower conveyor roller 3 and upper conveyor roller 4, and the drive gear 8 are installed at the ends of the lower conveyor roller 3 and upper conveyor roller 4 away from the motor 5. The protective box 1 is also equipped with a blowing mechanism 7 and a dust collection mechanism 9. The blowing mechanism 7 includes two sets of driven gears 701 movably connected to the outside of the protective box 1. The outer side of the driven gears 701 is fixed with a limit post 702. The dust collection mechanism 9 includes two sets of fixed tubes 904 installed on the upper and lower sides of the inner wall of the protective box 1. One end of the fixed tube 904 is rotatably connected to a movable tube 903 through a rotating shaft. A hose is connected between the movable tube 903 and the fixed tube 904. A dust collection nozzle is connected to one side of the movable tube 903 and the fixed tube 904.

[0025] The fiberglass cloth 6 is arranged in a Z-shape on the guide roller 2, the lower conveyor roller 3 and the upper conveyor roller 4. The fiberglass cloth 6 is horizontally distributed on both sides of the protective box 1, and vertically distributed between the lower conveyor roller 3 and the upper conveyor roller 4.

[0026] Two sets of blow pipes 704 are provided on both sides of the vertical side of the fiberglass cloth 6, and several nozzles 705 are provided on the surface of the blow pipes 704. Turntables 703 are connected and fixed at both ends of the blow pipes 704. The turntables 703 are hollow structures. One turntable 703 is fixed coaxially with the central axis of the driven gear 701. A rotary joint 706 is provided at the center of the other turntable 703, and the rotary joint 706 is connected to an air pump 707 through an air pipe.

[0027] In practice, the fiberglass cloth 6 is wound around the guide roller 2, the lower conveyor roller 3 and the upper conveyor roller 4, and two sets of motors 5 are started to drive the lower conveyor roller 3 and the upper conveyor roller 4 to rotate in opposite directions, so that the lower conveyor roller 3 and the upper conveyor roller 4 distributed on the upper and lower sides of the fiberglass cloth 6 can drive the fiberglass cloth 6 to automatically feed and convey in one direction.

[0028] The air pump 707 is connected to the rotary joint 706 via an air pipe. By starting the air pump 707, pressurized gas is delivered along the rotary joint 706 into the turntable 703 and the blowpipe 704. When the lower conveyor roller 3 and the upper conveyor roller 4 rotate, the drive gear 8 at the end meshes with the driven gear 701, causing the two sets of driven gears 701 to drive the two sets of turntables 703 and blowpipes 704 to rotate in opposite directions. At the same time, the rotational tangent direction of the turntables 703 and blowpipes 704 near the vertical side of the glass fiber cloth 6 is perpendicular to the glass fiber cloth 6. Since the vertical sides of the fiberglass cloth 6 move in opposite directions, when the two sets of blowing mechanisms 7 drive several nozzles 705 to spray towards the vertical side of the fiberglass cloth 6 through the blowing pipe 704, the dust adhering to the surface of the fiberglass cloth 6 can be efficiently separated. Furthermore, since multiple nozzles 705 are distributed on the same blowing pipe 704, it can be ensured that when the blowing pipe 704 close to the fiberglass cloth 6 is rotated to drive multiple nozzles 705 to blow gas, the airflow can be converted at different angles to cover the fiberglass cloth 6, so that the dust adhering to the fiberglass cloth 6 is blown away.

[0029] Please see Figure 1 , Figure 2 and Figure 4 A traction arm 901 is sleeved on the outside of the limiting post 702. A pull rod 902 is connected to the end of the traction arm 901 away from the limiting post 702. The pull rod 902 is fixed to one end of the movable tube 903. Two sets of fixed tubes 904 are connected to a dust collector 905 through a dust suction pipe. An induced draft fan 906 is installed on the dust collector 905.

[0030] The protective box 1 has an arc-shaped adjustment groove 10 on its surface near the traction arm 901. The central axis of the adjustment groove 10 coincides with the central axis of the rotating shaft between the movable tube 903 and the fixed tube 904. The pull rod 902 is connected to the adjustment groove 10 through it.

[0031] In specific implementation, when the driven gear 701 drives the limiting post 702 to rotate, the limiting post 702 revolves around the central axis of the driven gear 701. Thus, as the limiting post 702 rotates in a circle, it reciprocates by pushing and pulling the traction arm 901. This causes the pull rod 902 at one end of the traction arm 901 to reciprocate along the arc-shaped trajectory of the adjusting groove 10. Consequently, the pull rod 902 can drive the movable tube 903 at one end of the fixed tube 904 to reciprocate around the rotating shaft. When the induced draft fan 906 is started, it drives the removal of… When a negative pressure is generated inside the dust collector 905, the suction nozzles on the movable tube 903 and the fixed tube 904 will absorb the dust raised inside the protective box 1 and filter the dust through the dust collector 905. The reciprocating rotation of the movable tube 903 can drive the suction nozzles to reciprocate towards or away from the vertical side of the fiberglass cloth 6, so that the reciprocating movable tube 903 can absorb the moving dust, thereby enabling the automatic feeding mechanism of the weaving machine to conveniently and efficiently remove the dust attached to the fiberglass cloth 6.

[0032] In summary, the fiberglass cloth 6 is wound around the guide roller 2, the lower conveyor roller 3, and the upper conveyor roller 4. Two sets of motors 5 are started to drive the lower conveyor roller 3 and the upper conveyor roller 4 to rotate in opposite directions, so that the lower conveyor roller 3 and the upper conveyor roller 4 drive the fiberglass cloth 6 to automatically feed and convey in one direction. The air pump 707 and the blower 906 are started, so that the blower pipe 704 drives several nozzles 705 to spray onto the vertical side of the fiberglass cloth 6, which facilitates the separation of dust adhering to the fiberglass cloth 6. In addition, the dust suction nozzles on the movable pipe 903 and the fixed pipe 904 can absorb the dust raised inside the protective box 1, ensuring that the automatic feeding mechanism of the weaving machine can prevent dust from adhering to the fiberglass during conveying. The contents not described in detail in this description are prior art known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
