Description

Technical Field

[0001] This utility model relates to the field of masterbatch raw material dissolution technology, and in particular to a high-temperature dissolution device for masterbatch raw materials of composite fiber fabrics. Background Technology

[0002] High-temperature masterbatch raw material dissolving equipment is a specialized device used to dissolve or melt masterbatches, such as color masterbatches, functional masterbatches, and modified masterbatches, under high-temperature conditions to prepare intermediates or final products such as spinning solutions, modified plastics, and composite materials. This equipment is an industrial device that transforms solid masterbatch raw materials into a uniform molten or dissolved state through physical actions such as heating, shearing, and stirring. Its core purpose is to achieve uniform dispersion and complete dissolution of functional components in the masterbatch, such as pigments, additives, and polymers. The equipment provides sufficient temperature to melt or dissolve the masterbatch.

[0003] Existing equipment can usually only stir polymer raw materials to make them heat more fully, but it cannot break down the polymer raw materials, resulting in a long initial dissolution time for the polymer raw materials.

[0004] An existing patent (publication number: CN213221817U) discloses a high-temperature rapid dissolution device for polymer raw materials, which includes a dissolution tank. An upper connecting box is fixedly installed on the top of the dissolution tank via a fixing component. A stirring and crushing component is fixedly installed on the upper connecting box. The stirring and crushing component includes a mounting frame and a rotating disk. The mounting frame is fixedly installed on the upper side of the upper connecting box. This utility model relates to the field of polymer raw material processing technology. By setting up the stirring and crushing component, and through the cooperation of the driving gear, driven gear, and internal gear ring, the first stirring shaft and the second stirring shaft can drive the mixing and crushing blades to rotate in opposite directions, stirring and crushing the polymer raw materials. This greatly reduces the dead angle of stirring and crushing, making the stirring and crushing more uniform and thorough. At the same time, the crushing blades on one side of the stirring blades crush the polymer raw materials, improving the heating efficiency of the raw materials and greatly increasing the dissolution rate of the polymer raw materials.

[0005] To address the aforementioned issues, existing patents have proposed solutions that, through the setup of a stirring and crushing component and the engagement of a drive gear, a driven gear, and an internal gear ring, enable the first and second stirring shafts to rotate in opposite directions, thereby stirring and crushing the polymer raw materials. However, these solutions rely on the stirring and crushing component to achieve stirring of the raw materials, resulting in poor performance and an inability to effectively dissolve the raw materials at high temperatures. Summary of the Invention

[0006] The purpose of this invention is to provide a high-temperature dissolving device for masterbatch raw materials of composite fiber fabrics. The device uses a motor to drive an active helical gear to rotate, which in turn drives a transmission tube to rotate. This causes the spiral blades to transport the masterbatch raw materials from bottom to top within the device casing, thereby uniformly heating the masterbatch raw materials and ensuring a good dissolving effect. Furthermore, the rotation of the transmission tube drives an auxiliary rod to move, which can stir the masterbatch raw materials and improve the dissolving effect, thus solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-temperature dissolving device for masterbatch raw materials of composite fiber fabric, comprising a device shell, an inlet on the upper surface of the device shell, a stirring mechanism for stirring the raw materials at the upper end of the device shell, and an auxiliary mechanism for assisting in the dissolution of the raw materials on one side of the stirring mechanism;

[0008] The stirring mechanism includes a drive motor, which is fixed to the upper end of the equipment housing by bolts. The power output shaft of the drive motor is fixed with an active helical gear, and a driven helical gear meshes with one side of the active helical gear. A transmission tube penetrating the inner wall of the equipment housing is fixed to the inner wall of the driven helical gear, and a spiral blade is fixed to the outer surface of the transmission tube.

[0009] Preferably, two sets of auxiliary rods are symmetrically fixed on the outer surface of the transmission tube, and the end of the transmission tube is rotatably connected to the inside of the equipment housing through a bearing.

[0010] Preferably, the auxiliary mechanism includes an air pump, which is mounted on one side of the drive motor and fixed to the equipment housing by bolts, and the output end of the air pump is connected to a delivery pipe.

[0011] Preferably, the input end of the air pump is connected to a filter cartridge, and the end of the delivery pipe is connected to a connector.

[0012] Preferably, the inner wall of the connector has two fixed bearings sleeved on the transmission tube, and the upper end of the transmission tube has a through hole communicating with the connector.

[0013] Preferably, the transmission tube has a flow cavity communicating with the through hole inside, and the auxiliary rod has an air jet hole communicating with the flow cavity on its outer surface.

[0014] Preferably, a heating tube is installed at the lower end of the inside of the equipment shell, and a discharge pipe is connected to the lower surface of the equipment shell, with a valve fixed to the outer wall of the discharge pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the set stirring mechanism, the active helical gear is driven to rotate by the motor, which in turn drives the transmission tube to rotate, so that the spiral blades convey the masterbatch raw material in the equipment shell from bottom to top, thereby heating the masterbatch raw material evenly and ensuring the dissolution effect. In addition, when the transmission tube rotates, it will drive the auxiliary rod to move, which can stir the masterbatch raw material and improve the dissolution effect.

[0017] 2. Through the auxiliary mechanism and the through holes in the transmission pipe, high-pressure air is continuously input and enters the flow chamber. It is then discharged through the jet holes on the auxiliary rod, which forms tiny bubbles in the melt. This increases the internal turbulence of the material, enhances heat conduction and shear dispersion, and the gas flow can carry away the volatile byproducts produced during dissolution, promotes the positive shift of the dissolution equilibrium, shortens the dissolution time, and improves the practicality of the equipment.

Detailed Implementation

[0025] 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.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4 A high-temperature dissolving device for masterbatch raw materials of composite fiber fabric includes a device shell 1, a feed inlet 2 on the upper surface of the device shell 1, a stirring mechanism for stirring the raw materials at the upper end of the device shell 1, and an auxiliary mechanism for assisting in the dissolution of the raw materials on one side of the stirring mechanism.

[0028] The stirring mechanism includes a drive motor 3, which is fixed to the upper end of the equipment housing 1 by bolts. The power output shaft of the drive motor 3 is fixed with an active helical gear 31. One side of the active helical gear 31 is engaged with a driven helical gear 32. The inner wall of the driven helical gear 32 is fixed with a transmission pipe 33 that penetrates the inner wall of the equipment housing 1. The outer surface of the transmission pipe 33 is fixed with a spiral blade 34. Two sets of auxiliary rods 35 are symmetrically fixed on the outer surface of the transmission pipe 33. The end of the transmission pipe 33 is rotatably connected to the inside of the equipment housing 1 through a bearing. A heating pipe 5 is installed at the lower end of the inside of the equipment housing 1. The lower surface of the equipment housing 1 is connected to a discharge pipe 6. A valve 7 is fixed on the outer wall of the discharge pipe 6.

[0029] By adopting the above technical solution, before using the high-temperature dissolving equipment for the masterbatch raw materials of the composite fiber fabric, the outer shell 1 of the equipment is first placed in a suitable position. Then, the masterbatch raw materials to be processed are poured into the outer shell 1 through the feed port 2. The heating tube 5 inside the outer shell 1 is started by the external controller to dissolve the masterbatch raw materials at high temperature. The drive motor 3 is started by the controller, which drives the active helical gear 31 to rotate, causing the active helical gear 31 to mesh with the driven helical gear 32 to rotate, thereby driving the transmission tube 33 to rotate. The spiral blade 34 conveys the masterbatch raw materials in the outer shell 1 from bottom to top, thereby heating the masterbatch raw materials evenly and ensuring the dissolving effect. When the transmission tube 33 rotates, it will drive the auxiliary rod 35 to move, which can stir the masterbatch raw materials and improve the dissolving effect.

[0030] Specifically, such as Figure 2 , Figure 3 and Figure 4As shown, the auxiliary mechanism includes an air pump 4, which is mounted on one side of the drive motor 3 and fixed to the equipment housing 1 by bolts. The output end of the air pump 4 is connected to a delivery pipe 41, and the input end of the air pump 4 is connected to a filter cartridge 42. The end of the delivery pipe 41 is connected to a connector 43. The inner wall of the connector 43 is fixed with two fixed bearings 44 sleeved on the transmission pipe 33. The upper end of the transmission pipe 33 is provided with a through hole 45 that communicates with the connector 43. The inside of the transmission pipe 33 is provided with a flow cavity 46 that communicates with the through hole 45. The outer surface of the auxiliary rod 35 is provided with an air jet hole 47 that communicates with the flow cavity 46.

[0031] By adopting the above technical solution, the air pump 4 is started by the controller, which draws in external air. When the air passes through the filter cartridge 42, it can filter impurities in the air. Then, the air is delivered to the connector 43 through the delivery pipe 41. The fixed bearing 44 set in the connector 43 prevents the connector 43 from rotating when the transmission pipe 33 rotates. The high-pressure air continuously input through the through hole 45 on the transmission pipe 33 enters the flow chamber 46 through the through hole 45, and then is discharged through the jet hole 47 on the auxiliary rod 35. This causes the formation of microbubbles in the melt, which can increase the internal turbulence of the material, enhance the heat conduction and shear dispersion effect, and the gas flow can carry away the volatile by-products generated during dissolution, promote the positive shift of the dissolution equilibrium, shorten the dissolution time, and improve the practicality of the equipment. After the masterbatch is dissolved, the material is discharged to the outside by opening the valve 7 on the discharge pipe 6.

[0032] Working principle: The heating tube 5 inside the equipment shell 1 is started by an external controller, thereby melting the masterbatch raw material at high temperature. The drive motor 3 drives the active helical gear 31 to rotate, causing the active helical gear 31 to mesh with the driven helical gear 32 to rotate, which in turn drives the transmission tube 33 to rotate. This causes the spiral blades 34 to transport the masterbatch raw material inside the equipment shell 1 from bottom to top, thereby heating the masterbatch raw material evenly. When the transmission tube 33 rotates, it drives the auxiliary rod 35 to move, which can stir the masterbatch raw material. The air pump 4 is started by the controller, causing the air pump 4 to draw in external air. When the air passes through the filter cartridge 42, It can filter impurities in the air and then deliver the air to the connector 43 through the conveying pipe 41. The fixed bearing 44 set in the connector 43 prevents the connector 43 from rotating when the transmission pipe 33 rotates. The high-pressure air continuously input through the through hole 45 on the transmission pipe 33 enters the flow chamber 46 and is discharged through the jet hole 47 on the auxiliary rod 35, which makes the melt form micro bubbles, which can increase the internal turbulence of the material and enhance the heat conduction and shear dispersion effect. After the masterbatch is dissolved, the material is discharged to the outside by opening the valve 7 on the discharge pipe 6.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
