For the production of glass fiber sizing, a mixing device is usually used to mix the raw materials of glass fiber sizing to make glass fiber sizing. However, during the use of the existing mixing device, some raw materials will precipitate at the bottom of the device, and the mixing device does not have an anti-precipitation function, and cannot salvage or stir the raw materials precipitated at the bottom of the device, resulting in insufficient mixing of the raw materials and reducing the production quality of glass fiber sizing.

Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1-7 shown, an embodiment of a mixing device and method for producing glass fiber sizing agent provided in this embodiment.

[0021] A mixing device for the production of glass fiber sizing, including a base 1, a mixing device body 2 is fixedly installed on the top of the base 1, a feed pipe 3 is fixedly installed on the top of the mixing device body 2, a discharge pipe 4 is fixedly installed on the bottom of the mixing device body 2, and a sediment prevention mechanism 5 is arranged on the mixing device body 2. The sediment prevention mechanism 5 includes two fixing frames 6 symmetrically and fixedly installed on the surface of the mixing device body 2. A suction pump 7 is fixedly installed on one side of the fixing frame 6. A first delivery pipe 8 is fixedly installed on the bottom of the suction pump 7. A multi-pipeline suction pipe 9 connected to the first delivery pipe 8 is fixedly installed on the bottom of the inner wall of the suction pump 7. A second delivery pipe 10 extending into the mixing device body 2 is fixedly installed on the top of the suction pump 7; Further, the two multi-pipeline suction pipes 9 are symmetrically arranged at the bottom of the mixing device body 2 and are closely attached to the inner wall of the mixing device body 2. A plurality of suction nozzles 11 are evenly installed on the multi-pipeline suction pipe 9. A plurality of support rods 12 are fixedly installed on one side of the fixing frame 6. One end of the support rod 12 is fixedly installed with a plurality of first springs 13. A support plate 14 connected to the plurality of first springs 13 is arranged on one side of the suction pump 7. A protective plate 15 is installed on one side of the support plate 14. A sponge 16 is installed between the support plate 14 and the protective plate 15. A limiting groove 17 is formed on the support rod 12. A limiting rod 18 slidably connected to the limiting groove 17 is fixedly installed on one side of the support plate 14; Relying on the setting of the sediment prevention mechanism 5, the raw materials precipitated at the bottom of the mixing device body 2 can be sucked and salvaged and then re-injected into the mixing device body 2 through transportation. When the raw materials precipitate at the bottom of the mixing device body 2, the suction pumps 7 on both sides of the mixing device body 2 are started to generate suction force, and the precipitated raw materials are sucked and salvaged through the multi-pipeline suction pipes 9 located at the bottom of the inner wall of the mixing device body 2. Then, through the transportation of the first delivery pipe 8 and the second delivery pipe 10, the raw materials are re-injected into the mixing device body 2 and transferred to the upper part, so that they can be fully mixed, avoiding a reduction in the production quality of the glass fiber sizing. The multi-pipeline suction pipes 9 are symmetrically arranged on the mixing device body 2 and are closely attached to the inner wall, and a plurality of suction nozzles 11 are arranged on the multi-pipeline suction pipes 9, which can comprehensively suck the raw materials precipitated at the bottom of the mixing device body 2, avoiding the corners where suction cannot be achieved, so as to completely suck and salvage the precipitated raw materials. A protective plate 15 supported by support rods 12, first springs 13 and a support plate 14 is arranged on one side of the suction pump 7, which can protect the suction pump 7 and prevent the suction pump 7 from being damaged by collision. At the same time, after adding a sponge 16 between the support plate 14 and the protective plate 15, the anti-collision effect can be further improved, and the connection of the limiting groove 17 and the limiting rod 18 can limit the protective plate 15 to prevent left and right twisting and cause the first spring 13 to break.

[0022] Further, a motor 19 is provided on one side of the feed pipe 3 and is mounted on the mixing equipment body 2. The output end of the motor 19 extending into the interior of the mixing equipment body 2 is fixedly installed with a stirring shaft 20. A plurality of heating pipes 21 are fixedly installed on the stirring shaft 20. One side of the motor 19 is provided with a feed cylinder 22 mounted on the mixing equipment body 2. A support frame 23 is fixedly installed on the surface of the mixing equipment body 2. A batching box 24 is provided on the support frame 23. A scale plate 25 is installed on one side of the batching box 24. A plurality of electric telescopic rods 26 are symmetrically installed on the batching box 24. Two sealing plates 27 connected to the electric telescopic rods 26 are movably installed inside the batching box 24. A diversion frame 28 is fixedly installed at the bottom of the batching box 24. Grooves 29 are formed on both sides of the support frame 23. A second spring 30 is fixedly installed inside the grooves 29. One end of the second spring 30 is fixedly installed with a clamping rod 31. A plurality of clamping blocks 32 are fixedly installed on the surface of the batching box 24; The provided motor 19, stirring shaft 20 and heating pipes 21 can heat and stir the raw materials inside the mixing equipment body 2. Heating and stirring helps the components of the sizing agent to fully react and crosslink, forming a denser and more stable film structure. This film structure can better protect the glass fiber, improving its wear resistance and corrosion resistance. When adding additives, the batching box 24 and the scale plate 25 are relied on to quantitatively proportion the additives. Subsequently, multiple electric telescopic rods 26 are simultaneously activated to pull the two sealing plates 27 to both sides, causing the additives in the batching box 24 to fall and be introduced into the mixing equipment body 2 through the diversion frame 28 and the feed cylinder 22 to be mixed with the raw materials, making the dosage of the additives more accurate. More accurate supplementation of additives can further improve the production quality of the glass fiber sizing agent. The batching box 24 is fixed to the support frame 23 by engaging multiple clamping rods 31 with clamping blocks 32, enabling the batching box 24 to be detached from the support frame 23. This not only facilitates cleaning the interior of the batching box 24 but also allows for easy replacement of the batching box 24 according to different additives, avoiding a single mixing reaction when using the same batching box 24 for quantitative addition of additives and effectively preventing the impact on the production quality of the glass fiber sizing agent; Furthermore, the diameter of the bottom of the clamping block 32 matches the inner diameter of the groove 29, the diameter of the clamping rod 31 matches the inner diameter of the card slot on the clamping block 32. One end of the clamping rod 31 is set to be arc-shaped. The bottom of the diversion frame 28 is set to be rhombic and adapted to the inlet of the feed cylinder 22. Two cover plates 33 are symmetrically provided at the top of the batching box 24 and are movably installed through hinges; The diameter of the clamping block 32 is set to match the inner diameter of the groove 29, and at the same time, the diameter of the clamping rod 31 is set to match the inner diameter of the clamping groove on the clamping block 32. Under the condition of the matching of the diameter and the inner diameter, the connection of the two connection points is made tighter, thus effectively avoiding the shaking of the batching box 24. And after one end of the clamping rod 31 is set to be arc-shaped, it makes it easier for the clamping block 32 to squeeze the clamping rod 31 during disassembly and assembly. When the bottom of the diversion frame 28 is set to be adapted to the inlet of the feeding cylinder 22, after the batching box 24 is installed on the support frame 23, the bottom of the diversion frame 28 is in contact with the top of the feeding cylinder 22, making it easier for the additive in the batching box 24 to be introduced into the feeding cylinder 22 and fall into the mixing equipment body 2. Setting two cover plates 33 on the top of the batching box 24 can shield the inside of the batching box 24 when no production and processing is carried out, avoiding dust entry.

[0023] In this embodiment, as Figures 1-7 shown, the working process of a mixing equipment and method for producing glass fiber sizing agent provided in this embodiment is as follows: Step 1: Put the raw materials of the glass fiber sizing agent into the inside of the mixing equipment body 2 from the feeding pipe 3, start the motor 19 to drive the stirring shaft 20 to rotate, and start the heating pipe 21 to heat, and stir the raw materials inside the mixing equipment body 2 to make the raw materials mix to form sizing agent; Step 2: During the stirring and mixing process, there will be raw materials precipitating at the bottom of the mixing equipment body 2. At this time, start two suction pumps 7 at the same time and suck the precipitated raw materials through the multi-pipeline suction pipe 9 arranged at the bottom of the inner wall of the mixing equipment body 2, and discharge them again above the mixing equipment body 2 through the transmission of the first conveying pipe 8 and the second conveying pipe 10, so that the raw materials are stirred and mixed again; Step 3: Additives need to be put in when the raw materials are mixed. Pour the additives into the batching box 24, rely on the scale plate 25 to quantify the additives, and then start multiple electric telescopic rods 26 at the same time to pull the two sealing plates 27 to both sides, so that the additives in the batching box 24 fall and are introduced into the mixing equipment body 2 through the diversion frame 28 and the feeding cylinder 22 to be mixed with the raw materials; Step 4: When adding different additives, in order to avoid a single mixing reaction, the batching box 24 needs to be replaced. Since the batching box 24 and the support frame 23 are connected by the clamping of the clamping rod 31 and the clamping block 32, when disassembling and replacing, directly pull the batching box 24 upward to disassemble, and when installing, insert the clamping blocks 32 on both sides of the batching box 24 into the grooves 29 and clamp them with the clamping rod 31 to complete the installation.

[0024] In summary, in this embodiment, according to a mixing device and method for producing a glass fiber sizing agent in this embodiment, through the setting of the anti-precipitation mechanism 5, the raw materials precipitated at the bottom of the mixing device body 2 can be sucked and salvaged and then re-introduced into the mixing device body 2 through transportation. When the raw materials precipitate at the bottom of the mixing device body 2, the suction pumps 7 on both sides of the mixing device body 2 are started to generate suction, and the precipitated raw materials are sucked and salvaged through the multi-pipeline suction pipes 9 located at the bottom of the inner wall of the mixing device body 2. Then, through the transportation of the first conveying pipe 8 and the second conveying pipe 10, the raw materials are re-introduced into the mixing device body 2 and transferred to the upper part, so that they can be fully mixed, avoiding a reduction in the production quality of the glass fiber sizing agent. Moreover, the dosing tank 24 and the scale plate 25 are relied on to quantitatively proportion the additives, making the dosing amount of the additives more accurate. More accurate supplementation of the additives can further improve the production quality of the glass fiber sizing agent.
