Description

Technical Field

[0001] This utility model relates to the field of coating technology, and in particular to a handheld coating mixing device for mixing small quantities of coatings. Background Technology

[0002] In paint mixing scenarios, mixing small quantities of paint is a common requirement in home decoration repairs, color card sampling, and small-batch customized production. Traditional operations often involve manually mixing the paint by holding a stirring rod in the paint container. This is not only labor-intensive and inefficient, but also prone to problems such as paint layering and insufficient dispersion of color paste due to uneven stirring force and speed, which affects the final film quality.

[0003] Existing handheld electric paint mixing equipment mostly only has basic motor-driven mixing functions. However, during actual mixing, the mixing components are prone to colliding with the container wall due to gravity, resulting in poor stability when the equipment is used or temporarily placed inside the paint container. Furthermore, it is prone to shaking and tipping during high-speed mixing, posing safety hazards such as paint splashing and equipment falling off. To address this, a handheld paint mixing device for small-volume paint mixing is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a handheld paint mixing device for small-batch paint mixing to address the aforementioned technical problems. The height support unit, combined with the assembly groove and anti-bolt design of the housing connection part, allows for flexible adjustment of the relative height between the drive motor and the paint bucket, thereby adjusting the position of the agitator from the bottom of the bucket. This limits the minimum mixing height during mixing, thus preventing the agitator from easily contacting the bottom of the bucket during the mixing process. This reduces the impact of collisions on the paint bucket and agitator, as well as the impact and shaking of the paint bucket, improving safety during use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A handheld paint mixing device for small-batch paint mixing includes:

[0007] The drive motor, whose output end is connected to a stirring shaft, is used for the preparation of mixed coatings;

[0008] A housing is fitted onto the surface of the drive motor for fixation;

[0009] An adjustable support unit, which engages with the edge of the top of the paint cylinder to connect to the height support unit;

[0010] The height support unit is located above the adjustable support unit for assembly with the housing. The height support unit allows for adjustment of the distance between the agitator at the bottom of the stirring shaft and the bottom of the coating cylinder.

[0011] Furthermore, the adjustable support unit includes a central ring, a telescopic rod fixed to the outside of the central ring, and a fixed seat connected to the end of the telescopic rod.

[0012] Furthermore, the telescopic rod has four sections, which are evenly distributed along the circumference of the central ring.

[0013] Furthermore, the telescopic rod includes a main rod and a secondary rod that are slidably assembled with each other, and the surface of the main rod is threaded with a limiting bolt for limiting the position of the secondary rod;

[0014] The end of the main rod is fixed to the fixed base, and the end of the secondary rod is fixed to the central ring.

[0015] Furthermore, the fixing seat has a groove in the middle, through which the fixing seat can be engaged with the edge of the top of the paint cylinder, and the surface of the fixing seat is threaded with fixing bolts.

[0016] Furthermore, the height support unit includes a support frame fixed to the top of the central ring and a support column slidably sleeved on the surface of the support frame, and the surface of the support frame is threaded with adjustable bolts.

[0017] Furthermore, the two sides of the housing are fixed with connecting parts corresponding to the positions of the support columns. The surface of the connecting parts is provided with an assembly groove that is adapted to the support columns. The surface of the connecting parts is also threaded with abutment bolts for locking the support columns.

[0018] Furthermore, handles are fixed to both sides of the housing.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The handheld paint mixing device for small-batch paint mixing provided by this utility model features a height support unit with an assembly groove and anti-bolt design in the housing connection part. This allows for flexible adjustment of the relative height between the drive motor and the paint bucket, thereby adjusting the position of the agitator from the bottom of the bucket. This limits the minimum mixing height during mixing, preventing the agitator from easily contacting the bottom of the bucket during the mixing process. This reduces the impact of bumps and knocks on the paint bucket and agitator, as well as the impact and shaking of the paint bucket, thus improving safety during use.

[0021] Handles are provided on both sides of the casing for easy gripping and force application by the operator. Combined with the support unit, the motor can be temporarily supported on the height support unit during the mixing interval. This provides temporary vertical support for the drive motor, maintaining the stability of the device itself and facilitating the addition of coatings and other related operations, thus improving the flexibility of the equipment during use.

[0022] The adjustable support unit not only supports the height support unit during mixing, but also supports it to the ground after application, thus preventing the mixer from contacting the ground and causing contamination of the coating on it. Attached Figure Description

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0037] Example 1

[0038] Please refer to Figures 1-5 A handheld paint mixing device for small-batch paint mixing, comprising:

[0039] The drive motor 1, whose output end is connected to the stirring shaft 11, is used for the preparation of the mixed coating.

[0040] The housing 2 is fitted onto the surface of the drive motor 1 for fixation;

[0041] Adjustable support unit 3, which engages with the edge of the top of paint cylinder 5 for connecting height support unit 4;

[0042] The height support unit 4 is located above the adjustable support unit 3 for assembly with the housing 2. Under the action of the height support unit 4, the height of the stirrer 12 at the bottom of the stirring shaft 11 from the bottom of the coating cylinder 5 can be adjusted.

[0043] Because the handheld paint mixing device for small-volume paint mixing of this utility model has the above structure, when using it, first snap the adjustable support unit 3 into place on the top edge of the paint cylinder 5, and then assemble the housing 2 onto the height support unit 4 to start the drive motor 1 to carry out the mixing operation:

[0044] The height support unit 4 can drive the entire shell 2 to move vertically, so as to adjust the distance between the stirrer 12 and the bottom of the paint cylinder 5 during the stirring process. This can prevent the stirrer 12 from hitting the bottom and bumping against the cylinder wall, and prevent foreign matter debris from being mixed into the paint, thus greatly improving the operational flexibility in scenarios where a small amount of paint is mixed.

[0045] Example 2

[0046] The handheld paint mixing device for small-batch paint mixing provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, the adjustable support unit 3 includes a central ring 31, a telescopic rod 32 fixed to the outside of the central ring 31, and a fixed seat 33 connected to the end of the telescopic rod 32.

[0047] There are four telescopic rods 32, which are evenly distributed along the circumference of the central ring 31.

[0048] The telescopic rod 32 includes a main rod 320 and a secondary rod 321 that are slidably assembled with each other. The surface of the main rod 320 is threaded with a limiting bolt 322 for limiting the secondary rod 321.

[0049] The end of the main rod 320 is fixed to the fixed base 33, and the end of the secondary rod 321 is fixed to the central ring 31.

[0050] The fixing seat 33 has a groove 330 in the middle, through which the fixing seat 33 can be engaged with the edge of the top of the paint cylinder 5, and the surface of the fixing seat 33 is threaded with fixing bolts 34.

[0051] Because the handheld paint mixing device for small-volume paint mixing of this utility model has the above structure, the adjustable support unit 3 can slide relative to the main rod 320 and the auxiliary rod 321 of the telescopic rod, adapting to paint cylinders 5 of different diameters:

[0052] Specifically, after adjusting the length by pulling the telescopic rod 32, tightening the limit bolt 322 will complete the locking. Then, align the slot 330 of the fixing seat 33 with the top flange of the paint cylinder 5 and insert it. Finally, tighten the fixing bolt 34 to achieve a stable connection between the whole machine and the paint cylinder.

[0053] The four sets of equally spaced telescopic rods 32 can form a uniform ring support force, which can counteract the radial vibration of the motor during high-speed stirring and prevent the equipment from tipping over and paint from splashing. At the same time, the central ring 31 serves as a common connection reference for all telescopic rods and can coarsely position the vertical posture of the stirring shaft 11 during stirring to prevent the stirring shaft from eccentrically swinging and further ensure stirring stability.

[0054] Example 3

[0055] The handheld paint mixing equipment for small-batch paint mixing provided in Embodiment 1 or 2 has been further optimized, such as... Figure 3 and Figure 5 As shown, the height support unit 4 includes a support frame 41 fixed to the top of the central ring 31 and a support column 42 slidably sleeved on the surface of the support frame 41. An adjustable bolt 43 is threadedly connected to the surface of the support frame 41, and multiple threaded holes (e.g., [missing information]) are formed along its height direction on the surface of the support frame 41. Figure 5 As shown, the threaded hole is omitted in other views.

[0056] The housing 2 has a connecting part 21 fixed on both sides corresponding to the position of the support column 42. The surface of the connecting part 21 is provided with an assembly groove 22 that is adapted to the support column 42. The surface of the connecting part 21 is also threaded with an abutment bolt 24 for locking the support column 42.

[0057] Handles 23 are fixed to both sides of the other two sides of the housing 2.

[0058] Since the handheld paint mixing device for small-volume paint mixing of this utility model has the above structure, the support column 42 of the height support unit 4 can slide up and down along the support frame 41, and at this time, the top of the support column 42 is engaged in the corresponding assembly groove 22, and the rotating abutment bolt 24 locks and fixes the support column 42. Then, the minimum lowering height of the support column 42 can be positioned by the corresponding height threaded connection of the adjustable bolt 43 on the support frame 41. It should be noted that the position of the adjustable bolt 43 is fixed so that after the agitator 12 moves down to the minimum height, there is still a certain gap between it and the bottom wall of the paint cylinder 5.

[0059] In this way, when the shell 2 moves the support column 42 down to stir, it cannot move down further after contacting the adjustable bolt 43. At this time, the stirring shaft 11 will contact the bottom wall of the paint cylinder 5, thus avoiding collision with the bottom of the paint cylinder 5.

[0060] Furthermore, the housing 2 is relatively stable due to the support columns 42 on both sides of the bottom. This reduces the hand strength required to hold the housing 2 during operation, thus alleviating the labor intensity of the operator. At the same time, it can provide temporary support for the drive motor 1 and housing 2 when temporarily parked, facilitating operations such as adding color paste and sampling for testing.

[0061] like Figure 4 As shown, after the operation is completed, the entire equipment can be removed from the paint cylinder 5 and placed vertically on the ground through the height support unit 4. At this time, the agitator 12 is suspended in the air and does not contact the ground, which can avoid residual paint from polluting the ground and also reduce the wear of the agitator.

[0062] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0063] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
