[0002] Glass fiber mat is a non-woven material made of glass fiber through a wet-laid web process. It has the advantages of light weight, high strength, heat resistance, corrosion resistance, non-flammability, insulation, etc. It is widely used in construction, automobile, aviation, electronics, chemical industry and other fields. The production process of glass fiber mat mainly includes two steps: impregnation and drying. Impregnation refers to immersing the glass fiber mat in a glue solution containing adhesives and other additives so that it is evenly attached to the fibers and increases the strength and stability of the mat. Drying refers to sending the impregnated glass fiber mat into a dryer, and curing the glue solution through high-temperature heating to form a glass fiber mat with a certain thickness and density.

[0003] The glue liquid box contains glue liquid mixed with adhesives and other additives. A number of guide rollers are also provided in the glue liquid box. The glass fiber felt moving along the assembly line is guided into the glue liquid box by the guide rollers to achieve impregnation of the glass fiber felt, and the impregnated glass fiber felt is guided out of the glue liquid box by the remaining guide rollers so that it can enter the drying device. However, before impregnation, the glass fiber felt needs to be passed around the multiple guide rollers in the glue liquid box. Since some of the guide rollers are located at the inner bottom of the glue liquid box, the placement of the glass fiber felt is more troublesome, and the glue in the glue liquid box needs to be discharged, which takes a lot of time and is difficult to meet usage requirements.

DETAILED DESCRIPTION

[0021] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0022] like Figure 1-8As shown, a glass fiber mat impregnation and drying device includes an impregnation part and a drying part 1, the impregnation part includes an impregnation box 3, the upper end of the impregnation box 3 is open, and the two ends of the upper end of the impregnation box 3 are respectively provided with a feed roller 4 and a discharge roller 5, the interior of the impregnation box 3 is provided with at least one fixed roller 6, and the two sides of the fixed roller 6 are respectively provided with a downward pressing component, and the downward pressing component includes a guide rod 7, and the inner wall of the impregnation box 3 is provided with a groove 8 for the movement of the guide rod 7, and the outer surface of the impregnation box 3 is provided with a straight rack 9, and the upper end of the guide rod 7 is connected to the upper end of the straight rack 9 through a fixed plate 10, and the outer surface of the impregnation box 3 is provided with a mounting seat 11, and the mounting seat 11 is provided with a rotating shaft 12, and the mounting seat 11 is provided with a rotating shaft 12. A servo motor 13 for controlling the rotation of the rotating shaft 12 is provided on one side, a gear 14 meshing with the outside of the spur rack 9 is provided on the rotating shaft 12, a movable roller 15 is provided on the outer surface of the guide rod 7, a slot is provided at the end of the movable roller 15 away from the guide rod 7, a convex rod 16 is provided inside the slot, a spring 17 is provided at one end of the convex rod 16 and located inside the slot, a top block 19 is provided inside the impregnation box 3, a slope is provided at one end of the top block 19, a moving groove 22 is provided on the inner surface of the impregnation box 3, a slider 23 is provided inside the moving groove 22, slopes are provided on the upper and lower sides of the slider 23, and a groove 2 for accommodating the slope of the top block 19 is provided on the upper slope of the slider 23.

[0023] The impregnation section is used to immerse the glass fiber felt 2 into a glue solution containing adhesives and other additives, and the drying section 1 is used to solidify the glue solution. The drying section 1 adopts a traditional box-type drying equipment with an electric heating device inside. The glass fiber felt 2 passes through the drying section 1 and is quickly dried by the high temperature in the drying section 1 during the passing process.

[0024] The heights of the feed roller 4 and the discharge roller 5 are both higher than the height of the impregnation box 3, so that when the glass fiber felt 2 enters and leaves the impregnation box 3, the glass fiber felt 2 will not come into contact with the impregnation box 3, thereby reducing friction. The feed roller 4 and the discharge roller 5 are all rotatably connected to the impregnation box 3, thereby further reducing friction.

[0025] The fixed roller 6 is rotatably connected to the impregnation box 3 to reduce the friction between the fixed roller 6 and the glass fiber felt 2. The height of the fixed roller 6 is lower than that of the impregnation box 3. When the impregnation box 3 is filled with glue, the fixed roller 6 is completely located inside the glue, so that the glass fiber felt 2 can be immersed in the glue for a long time, so that the glue can fully enter the internal gaps of the glass fiber felt 2. When the glass fiber felt 2 is placed on the impregnation part, the height of the movable roller 15 is higher than that of the feed roller 4 and the discharge roller 5, and the glass fiber felt 2 is straightened and placed between the feed roller 4 and the discharge roller 5, and then the glass fiber felt 2 is squeezed downward by the movable roller 15. When the glass fiber felt 2 is placed, the height of the movable roller 15 is lower than that of the fixed roller 6, so that the moving path of the glass fiber felt 2 in the impregnation box 3 is increased, and the glass fiber felt 2 can be impregnated for a sufficient time without changing the moving speed of the glass fiber felt 2.

[0026] The servo motor 13 can drive the rotating shaft 12 and the gear 14 on the rotating shaft 12 to rotate. Through the engagement of the gear 14 with the spur rack 9, the spur rack 9 can be driven to move upward or downward, and then the guide rod 7 in the impregnation box 3 can be driven to move upward or downward, thereby changing the position of the movable roller 15 on the guide rod 7.

[0027] Since the movable roller 15 is fixed on one side of the guide rod 7, when the glass fiber mat 2 is moving, the movable roller 15 is subjected to the upward thrust applied by the glass fiber mat 2 for a long time, which may easily cause the movable roller 15 to loosen. Therefore, when the movable roller 15 moves downward, when the protruding rod 16 in the movable roller 15 contacts the top block 19, it will squeeze the spring 17 in the card slot, causing the protruding rod 16 to move toward the inside of the card slot. At this time, the protruding rod 16 moves to the bottom of the top block 19, and the upper side of the protruding rod 16 contacts the lower surface of the top block 19. The top block 19 can offset the upward thrust applied by the glass fiber mat 2 to the movable roller 15, which is beneficial to protect the movable roller 15 and prevent it from loosening. When the movable roller 15 needs to be taken out of the impregnation box 3, it only needs to continue to control the movable roller 1 5 moves downward. When the protruding rod 16 contacts the upper end of the slider 23, the spring 17 is also compressed, and the protruding rod 16 enters the inside of the slot. When the protruding rod 16 enters the lower side of the slider 23, the spring 17 pushes the protruding rod 16 out of the slot. At this time, the movable roller 15 can be controlled to move upward. The movable roller 15 drives the slider 23 to move upward along the movable slot 22 through the protruding rod 16. When the top block 19 abuts against the slider 23 to prevent it from moving upward, the protruding rod 16 is continuously squeezed, so that the protruding rod 16 moves into the slot. At this time, the protruding rod 16 can enter the upper surface of the top block 19 through the slider 23, so that the movable roller 15 can be moved from the inside of the dipping box 3 to the top of the dipping box 3. When the protruding rod 16 is separated from the slider 23, the slider 23 moves downward under the action of gravity.

[0028] Working principle: When placing the glass fiber felt 2 into the impregnation section, firstly, the guide rod 7 is controlled to move upwards by the servo motor 13, and the movable roller 15 is moved to above the feed roller 4 and the discharge roller 5, and then the glass fiber felt 2 is horizontally placed between the feed roller 4 and the discharge roller 5, and then the guide rod 7 is controlled to move downwards by the servo motor 13, and the movable roller 15 on the guide rod 7 squeezes the glass fiber felt 2 downwards, so that the moving path of the glass fiber felt 2 in the impregnation box 3 is increased, thereby increasing the impregnation time of the glass fiber felt 2, and when the protruding rod 16 moves to the lower surface of the top block 19, the stability of the movable roller 15 can be improved.

[0029] Furthermore, a liquid guide groove 24 is provided at one end of the impregnation box 3 near the discharge roller 5, and a liquid removal rod 25 is provided at the liquid guide groove 24. One end of the liquid removal rod 25 is hinged to the liquid guide groove 24, and a folding plate 26 is provided at the other end of the liquid removal rod 25. The inner side of the folding plate 26 is provided with a buckle groove, and the outer surface of the liquid guide groove 24 is provided with a card block 27 that matches the buckle groove. The upper surface of the liquid guide groove 24 is provided with an elastic block 28. The liquid guide groove 24 is inclined so that the glue falling into the liquid guide groove 24 can be diverted into the impregnation box 3. When the glass fiber felt 2 moves to the liquid guide groove 24 through the discharge roller 5, the glass fiber felt 2 The discharge roller 5 forms an extrusion therebetween, so that the excess glue on the lower surface of the glass fiber felt 2 can be squeezed into the liquid guiding groove 24 by the discharge roller 5. The excess glue on the upper surface of the glass fiber felt 2 can be squeezed out by the provided de-liquidating rod 25, and the squeezed glue falls into the impregnation box 3, thereby preventing waste caused by excessive glue on the glass fiber felt 2. The de-liquidating rod 25 can be interlocked with the block 27 through the buckle groove on the folding plate 26, and an upward thrust can be applied to the de-liquidating rod 25 through the elastic block 28, so that the slot and the block 27 are kept in a close fit state, thereby promoting the stable operation of the de-liquidating rod 25.

[0030] Furthermore, a liquid pump 29 is provided on one side of the immersion box 3. The liquid pump 29 has a liquid inlet pipe 30 and a liquid outlet pipe 31. One end of the liquid inlet pipe 30 is connected to the bottom of the immersion box 3. A hopper 21 is provided on one side of the immersion box 3. The lower end of the hopper 21 is connected to the immersion box 3. A filter net bag 20 is provided inside the upper end of the hopper 21. After a long period of use, the glue in the immersion box 3 will contain more impurities. The liquid inlet pipe 30 draws the glue liquid in the dipping box 3 from the bottom of the dipping box 3, and transports it to the hopper 21 through the liquid outlet pipe 31. The impurities in the glue liquid are separated by filtering through the filter net bag 20. When there are many impurities in the filter net bag 20, the filter net bag 20 can be taken out from the hopper 21. The filter net bag 20 and the hopper 21 are snap-fitted. At the same time, a ring plate is provided at the upper end of the filter net bag 20 to prevent the filter net bag 20 from falling into the hopper 21.

[0031] Furthermore, a protective shell 18 for sealing the gear 14 is provided on one side of the impregnation box 3 .

[0032] Furthermore, the length of the spur rack 9 is greater than that of the guide rod 7. The guide rod 7 is always located inside the groove 8. When the portion of the guide rod 7 inside the groove 8 is small, the stability of the guide rod 7 is reduced. By making the length of the spur rack 9 greater than that of the guide rod 7, the stability of the guide rod 7 can be improved, so that the movable roller 15 can be set at a position closer to the bottom of the guide rod 7, thereby increasing the moving path of the glass fiber felt 2 in the impregnation box 3.

[0033] The device can move the movable roller 15 in the impregnation box 3 to above the feed roller 4 and the discharge roller 5, so that the glass fiber felt 2 can horizontally pass between the movable roller 15 and the feed roller 4 and the discharge roller 5, and by controlling the movable roller 15 to move downward, the glass fiber felt 2 is pressed into the interior of the impregnation box 3, thereby completing the placement of the glass fiber felt 2, shortening the placement time, and improving the placement efficiency.
