Description

Technical Field

[0001] The invention relates to the technical field of glass fiber cloth processing, and in particular to a method for cleaning impurities in glass fiber cloth. Background Art

[0002] Glass fiber woven fabric is a plain fabric with untwisted roving, and is an important base material for hand-laid FRP. The strength of woven fabric is mainly in the warp and weft directions of the fabric. For occasions requiring high strength in the warp or weft directions, it can also be woven into a unidirectional fabric, which can arrange more untwisted rovings, single warp fabric, and single weft fabric in the warp or weft directions. During the production of glass fiber cloth, some impurities such as fine hairiness are easily generated on the surface. During the transmission of glass fiber cloth, it is very easy to absorb impurities, which will affect its use, reduce the effect of use, and be unfavorable for storage and further processing. When using glass fiber cloth with impurities, it is easy to affect the movement of various structures, reducing the service life of the structure. It is troublesome to manually clean up impurities such as fine hairiness, which increases labor intensity. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art, and the purpose is to provide a method for cleaning impurities based on glass fiber cloth, which can clean impurities attached to the surface of the fiber cloth and facilitate the rapid cleaning of adsorbed impurities.

[0004] The present invention is achieved through the following technical solutions:

[0005] A method for cleaning impurities from glass fiber cloth comprises the following steps:

[0006] 1) Place the glass fiber cloth on the transmission roller under the box body, and under the action of the first elastic member, press the arc-shaped baffle down on the surface of the glass fiber cloth;

[0007] 2) The driving roller blocks the impurities attached to the surface of the glass fiber cloth in the arc groove of the baffle while driving the glass fiber cloth to move;

[0008] 3) The suction force generated by the exhaust fan draws the impurities in the baffle into the box through the bellows;

[0009] 4) The gas exhausted by the exhaust fan enters the fixed box through the exhaust pipe, driving the movable sheet in the fixed box to rotate, thereby driving the movable shaft to rotate in the box;

[0010] 5) When the movable shaft rotates in the box, it drives the movable cylinder to rotate together, forcing most of the impurities sucked into the box to entangle on the movable cylinder, and a small amount of impurities are adsorbed on the filter net;

[0011] 6) When the impurities on the surface of the glass fiber cloth are cleaned, the horizontal plate is pulled outward. During the outward movement of the horizontal plate, the impurities at the bottom of the filter screen are scraped into the dust collecting box by using the dust collecting box provided;

[0012] 7) Remove the fixing plate, and push the movable cylinder out of the box body under the action of the third elastic member, so as to facilitate the cleaning of impurities wound around the movable cylinder;

[0013] The utility model comprises a plurality of supporting legs, a top plate is arranged on the top of the supporting legs, an exhaust fan is arranged at the bottom of the top plate, a box body is arranged on the air inlet of the exhaust fan, the bottom of the box body is an open structure, a filter assembly, a movable shaft, an inner support plate and a baffle of an arc structure are arranged in the box body from top to bottom, the movable shaft is horizontally inserted in the box body, a movable cylinder is arranged on the movable shaft, the movable cylinder is located in the box body, and the movable cylinder can rotate around the axis of the movable shaft together with the movable shaft, a plurality of blades are arranged on the circumferential outer wall of the movable cylinder, and an exhaust pipe is arranged at the air outlet of the exhaust fan A cylindrical fixed box is provided on the exhaust pipe, and the movable shaft is inserted into the fixed box. The fixed box is provided with a plurality of movable sheets, and the movable sheets are evenly distributed on the circumferential outer wall of the movable shaft. An exhaust port is also provided at the bottom of the fixed box. The gas discharged by the exhaust fan can push the movable sheets to drive the movable shaft to rotate; the inner support plate is located on the inner wall of the box body, and a first elastic member is provided at the bottom of the inner support plate, and the first elastic member is connected to the baffle plate. A first through hole is provided on the top of the baffle plate, and a second through hole is provided on the inner support plate. A bellows is also provided between the first through hole and the second through hole. When cleaning impurities attached to the surface of the fiber cloth, the technical solution uses the elastic force generated by the first elastic member to press the arc-shaped baffle plate down on the surface of the fiber cloth, so that the arc-shaped baffle plate can block the impurities on the surface of the glass yarn, and block the impurities in the arc-shaped groove of the baffle plate. Then, under the action of the exhaust fan, the impurities blocked in the arc-shaped groove of the baffle plate are sucked into the bellows. When the exhaust fan is working, the exhausted gas enters the fixed box under the action of the drain pipe, blowing the movable sheet in the fixed box to rotate, thereby driving the movable shaft to rotate together in the box body. During the rotation of the movable shaft, the movable cylinder sleeved on the movable shaft is driven to rotate together, thereby Most of the impurities entering the box through the bellows can be wound around the movable cylinder, and a small amount of impurities are adsorbed on the filter assembly, thereby achieving the cleaning of impurities attached to the surface of the glass yarn; on the one hand, the suction force generated by the exhaust fan provided in the technical solution can suck the impurities attached to the surface of the glass yarn into the box, thereby achieving the purpose of cleaning the impurities, and on the other hand, the gas discharged by the exhaust fan can drive the movable shaft to rotate, thereby driving the movable cylinder on the movable shaft to rotate, and the fine feathers and other impurities adsorbed into the box are wound around the movable cylinder, thereby improving the adsorption capacity of impurities. At the same time, when cleaning, it is only necessary to remove the movable cylinder mounted on the movable shaft to quickly clean the adsorbed impurities.

[0014] Furthermore, the filter assembly includes a horizontal plate and a filter screen, the horizontal plate is detachably connected to the box body, a third through hole is provided on the horizontal plate, and the filter screen is located in the through hole. The filter assembly is used to filter a small amount of impurities that are not wound around the movable shaft, so as to prevent these impurities from entering the exhaust fan through the air inlet of the exhaust fan and affecting the normal operation of the exhaust fan. The horizontal plate is detachably connected to the box body, so as to facilitate the extraction of the filter assembly from the box body and the cleaning of impurities attached to the filter screen.

[0015] Furthermore, a groove matching the horizontal plate is provided on one side of the inner wall of the box, and a fourth through hole with a thickness greater than that of the horizontal plate is provided on the other side of the inner wall of the box. One end of the horizontal plate is inserted into the groove through the fourth through hole, and the other end is located outside the box; a dust box with an open top is also provided on the outside of the box, and the dust box is located on the top of the horizontal plate. A notch is provided on the side wall of the dust box in contact with the box, and the notch is flush with the fourth through hole. The provided groove is used to place the horizontal plate, so that the horizontal plate can be fixed in the box. When in use, one end of the horizontal plate is inserted into the groove on the inner wall on the other side of the box through the fourth through hole on the side wall of the box, so as to achieve rapid installation of the filter assembly; at the same time, the provided dust box can clean and store impurities attached to the bottom of the filter. When it is necessary to clean the impurities attached to the bottom of the filter, the horizontal plate is pulled outward. In the process of moving outward, the horizontal plate uses the top of the dust box to scrape the impurities attached to the bottom of the filter, and the impurities on the filter fall into the dust box, so as to achieve rapid cleaning of the impurities on the filter. In order to prevent impurities attached to the scraper from being scraped off at the fourth through hole when the horizontal plate moves outward, the thickness of the fourth through hole is set to be greater than the thickness of the horizontal plate, ensuring that there is a certain gap between the bottom of the horizontal plate and the fourth through hole, so that impurities attached to the bottom of the filter can pass through the fourth through hole, and then the impurities are scraped into the dust box by using the dust box. The set dust box can scrape the impurities attached to the bottom of the filter into the dust box, and can also support the horizontal plate, and fix the horizontal plate in the box body with the set groove, and the set dust box can also block the fourth through hole.

[0016] Furthermore, the movable cylinder is provided with a connection hole, the movable shaft is located in the connection hole, both sides of the inner wall of the connection hole are provided with limit grooves, both sides of the outer wall of the movable shaft are provided with limit blocks, and the limit blocks are located in the limit grooves. In order to ensure that when the movable shaft rotates, the movable cylinder sleeved on the movable shaft can rotate together, the limit blocks and the limit grooves are provided, so that when the movable shaft rotates, the limit blocks located on the outer wall of the movable shaft can drive the movable cylinder to rotate together, thereby wrapping the impurities sucked into the box body around the movable cylinder.

[0017] Furthermore, a fifth through hole is provided on the side wall of the box, the movable shaft is located in the fifth through hole, a blocking plate matching the fifth through hole is provided in the fifth through hole, and the blocking plate is sleeved on the movable shaft, a fixing plate is provided on the movable shaft, the fixing plate is located on the outside of the blocking plate, and the fixing plate is connected to the movable shaft through a thread, and a second elastic member is provided between the fixing plate and the blocking plate. The fifth through hole is provided to facilitate the placement of the movable cylinder into the box, and also to facilitate the removal of the movable cylinder from the box. The blocking plate provided can not only fix the movable cylinder on the movable shaft under the action of the second elastic member, but also can block the fifth through hole. When it is necessary to remove the movable cylinder with impurities from the box, the fixing plate is loosened, the fixing plate and the second elastic member are removed from the movable shaft, and the force of the second elastic member on the blocking plate is removed, so that the blocking plate and the movable cylinder can be quickly removed from the box, so as to clean the impurities wrapped around the movable cylinder.

[0018] Furthermore, a third elastic member is provided on the inner wall of the box body away from the blocking plate, the elastic force of the third elastic member is smaller than the elastic force of the second elastic member, the third elastic member is sleeved on the movable shaft, one end of the third elastic member is connected to the inner wall of the box body, and the other end is provided with a connecting plate, and the connecting plate is sleeved on the movable shaft. Since the movable cylinder is installed in the box body, in order to facilitate the quick removal of the movable cylinder in the box body, a third elastic member is also provided in the box body, and the third elastic member is sleeved on the movable shaft. When the movable shaft is installed in the box body, the second elastic member allows the blocking plate to push the movable cylinder to compress the third elastic member. When the blocking plate is removed, the third elastic member can push the movable cylinder to be quickly removed from the box body.

[0019] Furthermore, a plurality of balls are provided at both ends of the movable cylinder, and annular grooves matching the balls are provided on the end surfaces of the connecting plate and the blocking plate facing the movable cylinder, and the balls are located in the annular grooves. Since the two ends of the movable cylinder are in contact with the blocking plate and the connecting plate respectively, in order to ensure the friction resistance between the blocking plate and the connecting plate when the movable cylinder rotates, the annular grooves and balls are provided so that the balls on the movable cylinder contact with the annular grooves on the blocking plate and the connecting plate, thereby reducing the contact area and ensuring that the movable cylinder can smoothly rotate between the blocking plate and the connecting plate.

[0020] Furthermore, a plurality of hooks are provided on the side walls of the blades, and the provided hooks can increase the entanglement effect of the impurities sucked into the box body and improve the adsorption capacity of the impurities.

[0021] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0022] 1. The present invention utilizes the suction force generated by the exhaust fan to suck the impurities blocked in the baffle of the arc structure into the box body, and at the same time, the gas discharged by the exhaust fan is passed into the fixed box to drive the movable shaft to rotate.
