[0002] Adding glass fiber in the production of gypsum board can not only increase the strength of the gypsum board, but also increase the fire resistance of the gypsum board, which makes glass fiber an indispensable raw material for gypsum board production. The stable feeding and uniform laying of glass fiber are important guarantees for the quality of gypsum board.

[0003] In the prior art, the glass fiber feeding device is composed of a storage hopper, a vibrating feeder, an intermediate hopper and a conveyor belt from upstream to downstream. The conveyor belt is an important device for conveying glass fiber to the gypsum slurry raw material over a long distance. The distribution of the glass fiber conveyed on it affects the laying uniformity after it enters the gypsum slurry. When conveying glass fiber, the existing belt conveyor is not only easy to stick to the side wall of the support plate of the belt conveyor due to the fluffy and easy adhesion characteristics of the glass fiber, but also difficult to effectively mix the glass fiber during conveying, thus affecting the feeding uniformity into the gypsum slurry.

[0004] Therefore, it is necessary to provide a glass fiber feeding device and system for gypsum board manufacturing to solve the problem of poor feeding uniformity when the glass fiber feeding device feeds the gypsum slurry in the prior art. Summary of the invention

[0010] Furthermore, the layering plate is detachably connected to the comb strip; wherein, the layering plate is provided with a plug hole for inserting the comb strip; a card slot is provided on the inner peripheral wall of the plug hole, and a deformation part is provided on the comb strip for clamping the comb strip in the card slot.

[0011] Furthermore, the deformation part includes a rubber pad protruding from the outer peripheral wall of the comb strip and fixed thereto; wherein the rubber pad can generate elastic deformation when the comb strip passes through the insertion hole and be inserted into the first card slot.

[0012] Furthermore, the deformation part includes a rubber ring arranged on the outer peripheral wall of the comb strip; a second clamping groove is provided on the peripheral wall of the comb strip for limiting the rubber ring; wherein, the inner diameter of the rubber ring is equal to the ring diameter of the second clamping groove, and the outer diameter of the rubber ring protrudes from the outer peripheral wall of the comb strip.

[0014] Furthermore, the guide surface of the guide plate is in the shape of a concave arc surface.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1-2 As shown, the present invention provides a glass fiber feeding device for gypsum board manufacturing, comprising:

[0036] Feed hopper 1;

[0037] The belt conveyor assembly 2 is arranged below the hopper 1 to receive the falling materials; the belt conveyor assembly 2 comprises symmetrically arranged support plates 21, between which transmission rollers 22 are axially connected, and a transmission belt 23 is stretched on the transmission roller 22, so that the transmission belt 23 forms a transmission rotation under the drive of the transmission roller 22;

[0038] Among them, a comb plate 24 is provided on the support plate 21, and the comb plate 24 is used to divert the material conveyed on the transmission belt 23 along its conveying direction; the comb plate 24 spans above the transmission belt 23, and a plurality of comb strips 241 extending toward the transmission belt 23 are provided on the comb plate 24 at intervals; a gap is left between the end of the comb strip 241 and the conveying surface of the transmission belt 23; a layering plate 242 is provided between the ends of adjacent comb strips 241, and the layering plate 242 is used to divert the material conveyed on the transmission belt 23 along a direction perpendicular to the conveying surface of the conveying belt 23.

[0039] The present invention aims to utilize the combing plates 24 and the layering plates 242 arranged perpendicularly to penetrate into the glass fibers to form a diversion effect in two directions, so as to simultaneously disperse and evenly mix the glass fibers transported along the transmission direction of the transmission belt 23 in two perpendicular directions. Since this process is realized in the process of transporting the glass fibers to the gypsum board forming process, the glass fibers evenly distributed on the transmission belt 23 can be directly added to the gypsum slurry to be formed to improve the performance of the gypsum board, thereby saving the time of using intermediate conveying equipment such as a blanking reamer to evenly distribute the glass fibers and then add them to the gypsum slurry, thereby improving production efficiency. Specifically, when the transmission belt 23 is driven at a uniform speed, the glass fibers fall evenly onto the transmission belt 23 through the discharge hopper 1 and are then transported in one direction. The portion of the glass fibers located in the lower layer close to the transmission belt 23 will first be evenly divided into multiple strands by the comb strip 241 along the conveying direction of the transmission belt 23 to avoid a large amount of accumulation of glass fibers in a local area on the transmission belt 23 during transportation. The portion of the glass fibers located in the upper layer away from the transmission belt 23 will be again divided into two strands by the layering plate 242 arranged above the end of the comb strip 241 along the vertical direction and then meet at the tail of the layering plate 242. Since the fluidity of the divided glass fibers is better, the overall uniformity of the re-intersecting glass fibers is better, so that the distribution of the glass fibers on the transmission belt 23 can be more even, thereby improving the uniformity and stability of the glass fibers when laid in the gypsum slurry, so that the performance of the gypsum board after molding is guaranteed.

[0040] In the above embodiment, the end of the layered plate 242 opposite to the flow direction of the glass fiber hinders the transportation of the glass fiber, causing a portion of the glass fiber to be intercepted by the layered plate 242, thereby reducing the transportation efficiency of the conveyor belt 23 for the glass fiber.

[0041] In order to solve the above problems, Figure 3 As shown, in the preferred embodiment provided by the present invention based on the above embodiment, the layered plate 242 is a wedge-shaped plate;

[0042] The thickness of the layered plate 242 gradually increases along the material conveying direction; the end of the layered plate 242 is provided with a guide arc surface 242a along the material conveying direction for guiding the material along the oblique upward direction to the wedge surface of the layered plate 242.

[0043] In this embodiment, by setting the guide arc surface 242a, part of the glass fibers distributed in the upper layer can be guided upward to the wedge surface of the layering plate 242 for transportation, thereby preventing part of the glass fibers from being intercepted by the end surface of the layering plate 242 when the layering plate 242 diverts the glass fibers. This can improve the conveying efficiency of the conveyor belt 23 for the glass fibers and improve the uniform distribution effect on the conveyor belt 23.

[0044] In the above embodiment, although the glass fibers can be guided to pass above and below the layering plate 242 respectively during the transportation process, the friction resistance encountered by the glass fibers when moving on the wedge surface of the layering plate 242 can easily cause local accumulation, which is not conducive to improving the glass fiber transmission efficiency of the transmission belt 23.

[0045] In order to solve the above problems, Figure 4 As shown, in the preferred embodiment provided by the present invention based on the above embodiment, a groove 243 penetrating along the inclined direction of the wedge surface of the layering plate 242 is provided, and the groove 243 is used to divert the material flowing through the layering plate 242;

[0046] Among them, multiple grooves 243 are equidistantly arranged on the layered plate 242; a second guide arc surface 242b is arranged at the end of the groove 243 along the material transmission direction for guiding the material into the groove 243 along an upward inclined direction; the arc surface height of the second guide arc surface 242b is lower than that of the first guide arc surface 242a.

[0047] In this embodiment, grooves 243 are provided on the upper wedge surface of the layered plate 242, so that the glass fibers can simultaneously pass through the inside of the grooves 243 and the wedge surface of the layered plate 242 between adjacent grooves 243 during transmission above the layered plate 242, thereby enabling the glass fibers to be staggered and transmitted with a smaller stacking thickness during the transportation process, thereby avoiding accumulation on the wedge surface of the layered plate 242.

[0048] In order to facilitate the installation between the comb strips 241 and the layered plates 242, and to avoid the adhesion of glass fibers during long-term use and the inability to clean and replace them in time, Figure 5 , 6 As shown, in another embodiment provided by the present invention based on the above embodiment, the layered plate 242 is detachably connected to the comb strip 241;

[0049] The layered plate 242 is provided with an insertion hole 244 for inserting the comb strip 241 ; the inner peripheral wall of the insertion hole 244 is provided with a card slot 245 , and the comb strip 241 is provided with a deformation portion 25 for locking the comb strip 241 in the card slot 245 .

[0050] More specifically, the deformation portion 25 includes a rubber pad 251 protruding from the outer peripheral wall of the comb strip 241 and fixed thereto;

[0051] The rubber pad 251 can be elastically deformed and inserted into the first card slot 245 when the comb strip 241 passes through the insertion hole 244 .

[0052] In the above embodiment, the rubber pad 251 is fixed on the comb strip 241 and is easily worn during installation and removal, making it difficult to replace, resulting in inconvenience in use.

[0053] In order to solve the above problems, Figure 7 As shown, in the preferred embodiment provided by the present invention based on the above embodiment, the deformation part 25 includes a rubber ring 252 arranged on the outer peripheral wall of the comb strip 241; a second card groove 246 is arranged on the peripheral wall of the comb strip 241 to limit the rubber ring 252;

[0054] The inner diameter of the rubber ring 252 is equal to the ring diameter of the second clamping groove 246 , and the outer diameter of the rubber ring 252 protrudes from the outer peripheral wall of the comb strip 241 .

[0055] In this embodiment, the problem of position limitation and the need for replacement is solved by providing the rubber ring 252 .

[0056] In the above embodiment, when the glass fibers are conveyed on the transmission belt 23, due to the lack of limiting means on both sides of the glass fibers, the glass fibers may be gradually pushed and dispersed to both sides of the transmission belt 23 due to the large amount of glass fibers accumulated in the middle of the transmission belt 23 or the bulge in the middle of the transmission belt 23 during the conveying process, thereby causing the glass fibers to adhere to the sides of the support plate 21, thereby reducing the conveying efficiency of the glass fibers.

[0057] In order to solve the above problems, Figure 8 As shown, in another embodiment provided by the present invention based on the above embodiment, guide plates 26 are symmetrically provided on the comb plate 24, and the guide plates 26 are used to guide the material conveyed on the transmission belt 23 to the middle of the transmission belt 23;

[0058] The side wall of the guide plate 26 is inclined toward the middle of the transmission belt 23 along the conveying direction of the material to form a guide surface for the material.

[0059] More specifically, in order to improve the drainage effect of the guide plate 26 on the glass fiber during the conveying process, as shown in FIG. Fig. 9 As shown, the guide surface of the guide plate 26 is in the shape of a concave arc surface.

[0060] In this embodiment, by providing arc-shaped guide plates 26 on both sides of the transmission belt 23, the movement path of the glass fiber can be changed and moved closer to the middle of the transmission belt 23, thereby preventing the glass fiber from being gradually pushed to the side wall of the support plate 21 and adhering to it during the transportation process, thereby improving the transportation efficiency of the glass fiber.

[0061] In order to reduce the adhesion area of ​​the glass fiber on the guide plate 26 and enhance the passability of the glass fiber when it contacts the guide plate 2, please continue to refer to Fig. 9As shown, a through hole 261 is formed on the guide plate 26;

[0062] The axis of the through hole 261 coincides with the normal direction of the guide surface.

[0063] The present invention further provides a glass fiber feeding system, which is applied with the glass fiber feeding device provided by any of the above embodiments, and the system comprises:

[0064] A storage hopper 3, which is used to store glass fibers;

[0065] A vibrating feeder 4, which is used to control the glass fibers in the storage hopper 3 to fall;

[0066] More specifically, a distance measuring sensor is provided in the feeding hopper 1 to feed back the thickness of the material layer in the feeding hopper 1 to the vibrating feeder 4 , so that the vibrating feeder 4 can discharge the material into the feeding hopper 1 at a fixed time and frequency.

[0067] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
