Description

Technical Field

[0001] This utility model relates to the field of spray material processing technology, and in particular to a mixing and stirring device for spray material processing. Background Technology

[0002] In the production and processing of spray coating materials, mixing equipment is the key to achieving uniform mixing of powders, liquids, and additives. Its performance directly affects the particle size distribution, compositional uniformity, and final application effect of the spray coating material. Currently, due to different application scenarios, spray coating materials often require the mixing of various components such as resins, solvents, pigments, curing agents, and functional additives in specific proportions to form a mixture with specific viscosity, suspension properties, and stability.

[0003] However, in the prior art, for example, Chinese Publication No. CN223010314U, a mixing and blending device for spraying material processing includes a base, a first support frame, a second support frame, a drive motor, a first rotating rod, a second rotating rod, a mixing tank, a threaded rod, and a support seat. The first support frame is fixedly installed on the top of the base, and the second support frame is slidably installed on the top of the first support frame. The drive motor is provided on the top of the second support frame.

[0004] This invention, through its control mechanism, can control the distance the second rotating rod sinks into the mixing tank for mixing. Once the second rotating rod has sunk to the appropriate distance, the threaded rod is fixed, preventing further rotation of the lifting mechanism and allowing the operator to move the second rotating rod to the desired position. This achieves automatic positioning of the second rotating rod and improves the mixing effect of the device. However, during use, it can be observed that the fixed mixing structure, using only a single rotating shaft to drive the mixing blades, only allows for single radial or axial fluid movement. When processing high-viscosity materials, this can easily lead to dead zones in the mixing, causing material to accumulate on the tank wall. Furthermore, for mixtures containing lightweight powders and heavy particles, a single shear force is insufficient to break up particle agglomerates, easily resulting in uneven density and affecting the atomization effect during spraying. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing stirring structure has a fixed form and is difficult to adapt to the characteristics of multi-component materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a mixing and blending device for spraying material processing, comprising: a mounting base; a fixed arm, fixedly installed on the upper end of the mounting base, with a feeding component installed on its upper end; a mounting frame, disposed on one side of the fixed arm, with a mixing component installed on its upper end; and a conveying pipe, one end of which is connected to and communicates with the end of the mixing component, and the other end of which is connected to the end of the feeding component through a flange.

[0007] The technical effect of adopting the above-mentioned further solution is that the overall structure is fixed by the mounting base, the feeding component on the fixed arm realizes the supply of raw materials, the mixing component on the mounting frame completes the mixing, and the conveying pipe connects the two through the flange to realize the material transfer. It can efficiently complete the feeding, mixing and conveying of the spraying material, and improve the continuity and uniformity of material mixing during processing.

[0008] In a preferred embodiment, the mixing assembly includes: a mixing chamber disposed above the mounting frame; a second stirring shaft rotatably disposed inside the mixing chamber along the axial direction of the mixing chamber; multiple sets of second stirring columns welded to the outer surface of the second stirring shaft; a second motor connected to the end of the second stirring shaft; and a feeding trough connected to one side of the mixing chamber, communicating with the mixing chamber, and having its upper end connected to a conveying pipe.

[0009] The technical advantages of adopting the above-mentioned further solution are as follows: the mixing chamber is supported by a mounting frame, and the second motor drives the second stirring shaft to rotate, thereby driving multiple sets of welded second stirring columns to stir within the chamber. The material conveyed by the conveying pipe enters the mixing chamber through the feeding trough. Through the synergistic action of the stirring shaft and the stirring columns, efficient mixing of the spraying material is achieved, ensuring the uniformity of material mixing and the continuity of processing.

[0010] In a preferred embodiment, the mixing assembly further includes: a driven gear, fixedly connected to the end of the mixing chamber; a transmission gear, disposed on one side of the driven gear and cooperating with the driven gear; a drive motor, disposed on one side of the transmission gear; and a rotating shaft, one end of which is connected to the output end of the drive motor, and the other end of which is fixedly connected to the transmission gear.

[0011] The technical effect of adopting the above-mentioned further solution is as follows: the drive motor drives the transmission gear to rotate through the rotating shaft, and the transmission gear meshes with the driven gear at the end of the mixing chamber, driving the mixing chamber to rotate. Combined with the original stirring shaft and stirring column, it forms a dual effect of chamber rotation and internal stirring, further improving the mixing efficiency and uniformity of the sprayed material and enhancing processing stability.

[0012] In a preferred embodiment, the mixing assembly further includes: a heating chamber disposed outside the mixing chamber; two limiting blocks, fixedly connected to the left and right ends of the mixing chamber; and limiting slots disposed at the left and right ends of the heating chamber and cooperating with the limiting blocks.

[0013] The technical advantages of adopting the above-mentioned further solution are as follows: A heating chamber is provided outside the mixing chamber, and the left and right end limiting blocks are fixed in conjunction with the limiting slots of the heating chamber. The heating chamber heats the mixing chamber, and with the dual stirring of the mixing chamber rotation and the internal stirring shaft and stirring column, the material fusion is enhanced in the heating environment. The limiting structure ensures heating stability, improves the mixing efficiency and uniformity of the sprayed material, and is suitable for processing requirements that require temperature control.

[0014] In a preferred embodiment, the feeding assembly includes: a storage tank installed between the fixed arms; a sealing cover covering the upper end of the storage tank, with a feeding port extending through it; a first stirring shaft rotatably disposed inside the storage tank; multiple sets of first stirring columns welded to the outer surface of the first stirring shaft; and a first motor disposed at the end of the first stirring shaft.

[0015] The technical advantages of adopting the above-mentioned further solution are: the storage tank is supported by a fixed arm, and the sealing cover and filling port facilitate the addition of raw materials. The first motor drives the first stirring shaft to rotate, which in turn drives multiple sets of welded first stirring columns to stir within the storage tank, preventing the raw materials from settling and clumping.

[0016] In a preferred embodiment, the feeding assembly further includes: a feeding port, which is located at the lower end of the storage tank and communicates with the storage tank; a fixed blade, which is fixedly located at the lower end of the feeding port; and a movable blade, which is fixedly connected to the lower end of the first stirring shaft.

[0017] The technical effect of adopting the above-mentioned further solution is that when the first stirring shaft rotates, the moving blades and the fixed blades alternately overlap and stagger, achieving regular material feeding. Combined with the pre-mixing function, this prevents raw material clumping and precisely controls the feeding amount, ensuring stable material supply in subsequent mixing stages.

[0018] In a preferred embodiment, the outer surface of the mixing chamber is provided with a plurality of heat-conducting holes.

[0019] The technical effect of adopting the above-mentioned further solution is that: several through heat-conducting holes are provided on the outer surface of the mixing chamber, which, together with the external heating chamber, enable heat to be efficiently conducted to the material inside the chamber through the heat-conducting holes.

[0020] In a preferred embodiment, the bottom of the mixing chamber is provided with a collection port, and the end of the collection port passes through the heating chamber and is connected to a cover.

[0021] The technical advantage of adopting the above-mentioned further solution is that after mixing, the material can be discharged through the collection port by opening the lid, making the operation convenient.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. This utility model device breaks through the limitations of fixed stirring structures in existing technologies by innovatively adopting a dual stirring mode of "rotation + revolution". In the mixing component, the second stirring shaft drives the second stirring column to rotate at high speed, forming axial shear stirring of the material entering the mixing chamber; at the same time, the drive motor drives the entire mixing chamber to revolve through gear transmission, so that the material continuously changes the contact angle and force direction with the stirring column under the action of centrifugal force. This dynamic stirring structure can flexibly adjust the stirring intensity according to the density and viscosity differences of multi-component materials. For example, for heavy components that are easy to settle, the centrifugal force generated by revolution can effectively prevent their deposition; for components with high viscosity, the shearing action of the rotating stirring column can break up the agglomeration phenomenon, solving the problem that traditional fixed stirring structures cannot take into account the uniformity of mixing materials with different physical properties.

[0024] 2. This utility model addresses the diverse temperature and feeding rate requirements of multi-component materials by designing an independently adjustable temperature control and feeding module. The heating chamber achieves uniform heating of the mixing chamber through heat conduction holes, and the temperature can be precisely set according to the material characteristics, avoiding the problem of some components being deactivated or having insufficient flowability due to a single temperature setting.

Detailed Implementation

[0031] 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.

[0032] Example 1:

[0033] Please see Figure 1-4 This utility model provides a technical solution: a mixing and stirring device for processing spray coating materials, including a mounting base 1. Symmetrically distributed fixed arms 2 are bolted to the upper surface of the mounting base 1. A feeding assembly is mounted on the top of each fixed arm 2 for temporarily storing and initially processing the raw materials for spray coating. A mounting frame 3 is provided on one side of each fixed arm 2, and is fixedly connected to the mounting base 1 by welding. The upper end of the mounting frame 3 supports the mixing assembly, which is responsible for deep mixing of the raw materials. To facilitate the transfer of raw materials, a conveying pipe 22 is connected to the end of the mixing assembly. The conveying pipe 22 communicates with the internal cavity of the mixing assembly, and the end of the conveying pipe 22 furthest from the mixing assembly is tightly connected to the discharge port of the feeding assembly via a flange, ensuring no leakage of raw materials during transfer.

[0034] The equipment, through its separate design of the feeding component and the mixing component, combined with the directional transmission of the conveying pipe 22, achieves an orderly connection between raw material storage and mixing processing. This not only improves the space utilization of the equipment but also ensures that the raw materials are not contaminated by the outside world during the transmission process, providing a basic guarantee for the mixing quality of the spraying materials.

[0035] Example 2:

[0036] like Figure 1-4 As shown, based on Embodiment 1, this embodiment further optimizes the structure of the mixing component. The core of the mixing component is the mixing chamber 15, which is horizontally mounted above the mounting frame 3 via a bracket. A second stirring shaft 25 is rotatably mounted along the central axis of the mixing chamber 15. Multiple sets of second stirring columns 26 are uniformly welded to the outer surface of the second stirring shaft 25, and the second stirring columns 26 are distributed in a spiral shape. The end of the second stirring shaft 25 is fixedly connected to the output shaft of the second motor 27 via a coupling, and the second motor 27 drives the second stirring shaft 25 and the second stirring columns 26 to rotate synchronously. A feed trough 21 is integrally connected to one side of the mixing chamber 15. The feed trough 21 is connected to the interior of the mixing chamber 15, and the upper opening of the feed trough 21 is connected to the bottom end of the conveying pipe 22 through a pipe joint, so that the raw materials conveyed by the feeding component smoothly enter the mixing chamber 15 through the feed trough 21.

[0037] Meanwhile, a driven gear 17 is fixedly sleeved at the end of the mixing chamber 15. A transmission gear 18 meshes with one side of the driven gear 17. The transmission gear 18 is connected to the output end of the drive motor 20 through a rotating shaft 19. One end of the rotating shaft 19 is keyed to the output shaft of the drive motor 20, and the other end is fixedly welded to the central shaft of the transmission gear 18. When the drive motor 20 starts, it drives the transmission gear 18 to rotate through the rotating shaft 19, thereby driving the driven gear 17 and the mixing chamber 15 to rotate as a whole.

[0038] This structure combines the rotation of the second stirring shaft 25 with the revolution of the mixing chamber 15, so that the raw materials are simultaneously subjected to axial stirring force and centrifugal force in the circumferential direction within the mixing chamber 15, which greatly improves the mixing uniformity of the raw materials and solves the problem of insufficient mixing in traditional stirring equipment.

[0039] Example 3:

[0040] like Figure 1-4 As shown, based on Embodiment 2, this embodiment adds a heating and feeding control structure to the mixing component. A heating chamber 13 is sleeved on the outside of the mixing chamber 15. The inner sidewalls of the left and right ends of the heating chamber 13 are provided with limiting slots 24 that are adapted to the limiting blocks 23 fixed on the left and right ends of the mixing chamber 15. The limiting blocks 23 are embedded in the limiting slots 24, so that a stable annular heating space is formed between the heating chamber 13 and the mixing chamber 15, without affecting the rotational movement of the mixing chamber 15. A plurality of heat-conducting holes 16 are uniformly provided on the outer surface of the mixing chamber 15 to ensure that the heat in the heating chamber 13 can be transferred to the interior of the mixing chamber 15 through the heat-conducting holes 16.

[0041] Regarding the feeding components, a storage tank 4 is installed between the fixed arms 2. A sealing cover 7 is fitted over the upper end of the storage tank 4, and a feeding port 12 is provided through the sealing cover 7 for easy addition of raw materials. A first stirring shaft 8 is rotatably mounted inside the storage tank 4. Multiple sets of first stirring columns 9 are welded to the outer surface of the first stirring shaft 8, and the end of the first stirring shaft 8 is connected to the output shaft of the first motor 11. A feeding port 5 is provided at the lower end of the storage tank 4, with a fixed blade 6 fixed at the lower end of the feeding port 5. A movable blade 10 is fixed at the lower end of the first stirring shaft 8. When the first stirring shaft 8 rotates, the movable blade 10 and the fixed blade 6 continuously overlap and offset, achieving quantitative and regular feeding of the raw materials. A collection port 14 is provided at the bottom of the mixing chamber 15, and the end of the collection port 14 passes through the heating chamber 13 and is connected to a cover for easy removal of the mixed material.

[0042] The structure, through the temperature control function of the heating chamber 13, can adjust the mixing temperature according to the characteristics of the spraying material, avoiding the raw materials from clumping due to unsuitable temperature; while the cooperation between the movable blade 10 and the fixed blade 6 enables precise feeding of the raw materials, effectively controlling the mixing ratio of the raw materials, and further improving the mixing quality of the spraying material.

[0043] Working Principle: This equipment is a mixing and stirring device for spray coating material processing. During use, the heating temperature of the heating chamber 13 is first set according to the characteristics of the raw materials to ensure that the raw materials maintain suitable fluidity during the mixing process. Then, the first motor 11 is started, driving the first stirring shaft 8 inside the storage tank 4 to rotate. The first stirring column 9 rotates with the shaft to initially stir the raw materials, preventing them from settling and clumping. Simultaneously, the movable blades 10 at the lower end of the first stirring shaft 8 continuously overlap and offset with the fixed blades 6 at the discharge port 5, feeding the raw materials into the conveying pipe 22 through the discharge port 5 at a set rate.

[0044] The raw materials are conveyed to the feed trough 21 via the feed pipe 22, and then enter the mixing chamber 15. At this time, the second motor 27 and the drive motor 20 are started simultaneously. The second motor 27 drives the second stirring shaft 25 and the second stirring column 26 on its outer surface to rotate at high speed in the mixing chamber 15, axially stirring the incoming raw materials. The drive motor 20 drives the transmission gear 18 to rotate via the rotating shaft 19. The driven gear 17, which meshes with the transmission gear 18, drives the mixing chamber 15 to rotate as a whole, so that the raw materials come into full contact with the second stirring column 26 under the action of centrifugal force.

[0045] During the mixing process, the heat generated in the heating chamber 13 is transferred to the interior through the heat-conducting holes 16 on the outer surface of the mixing chamber 15, ensuring that the raw materials are mixed at a suitable temperature. After mixing is complete, the first motor 11 is turned off to stop feeding, while the second motor 27 and drive motor 20 continue to run for a few minutes to ensure that the raw materials in the chamber are mixed evenly. Finally, all motors are turned off, and after the mixing chamber 15 stops rotating, the cover of the collection port 14 at the bottom of the mixing chamber 15 is opened, and the mixed spraying material flows out through the collection port 14, completing the entire stirring and mixing operation. After the operation, any residual raw materials inside the equipment must be cleaned to keep the equipment clean for the next use.

[0046] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
