Description

Technical Field

[0001] This invention relates to the field of paint coating technology, and more particularly to a perforated ball bead paint coating apparatus, method and application. Background Technology

[0002] Besides traditional brushing, common painting methods include spraying, electrodeposition coating, and dip coating. Spraying includes air spraying, electrostatic spraying, dual-nozzle spraying, and aerosol spraying. Electroposition coating produces a uniform coating, high paint utilization, low pollution, low energy consumption, and is easily automated and continuous, making it suitable for primer coating of complex workpieces. Dip coating is suitable for coating small, irregularly shaped hardware.

[0003] A ball painting machine CN95209541.6, see Figure 1 The device consists of a conveying device, a rotating device, a support frame, and a coating device. The conveying device operates in a cyclical manner, and the rotating device is connected to the conveying device by bearings. The support frame can be combined with or removed from the rotating device, and clamping pins are provided on both sides of the support frame to fix the balls. The coating devices are evenly distributed at the upper, middle, and lower ends of one side of the conveying device. This device uses a spraying method to coat the colored balls. However, it has the following disadvantages: 1) The device is complex and requires large-scale equipment for assembly line operations. 2) The paint utilization rate is low due to the spraying method.

[0004] A mixing device for paint processing (CN202011640198.1, see...) Figure 2 This invention relates to the field of paint processing. It includes a mixing tank with an equipment box mounted at the bottom. Inside the equipment box is a drive unit, and mixing blades are fixedly mounted on the output shaft of the equipment box. The rotation of the mixing blades causes the elastic levers on the mixing blades to be intermittently stretched by the locking blocks on the idler, which in turn causes a rocker arm to move a movable ball for adjustment. This, in turn, causes the inner ball to be restricted by an adjusting rod, which in turn restricts the limiting rod, causing it to adjust synchronously. This results in the upper and lower blocks tumbling and moving within the paint, creating a tumbling effect during the mixing process. However, it has the following disadvantages: it does not involve ball coating, it is a mixing device, and the device structure is complex.

[0005] Given the scarcity of coating materials and the need to prevent collisions between beads during coating, a solution is needed for small-batch coating of perforated beads. Spraying or dip coating is unsuitable to avoid material waste. Electrodeposition is also unsuitable, as it is only suitable for water-soluble coating materials. Furthermore, both spraying and electrodeposition require complex equipment. Therefore, it is necessary to design a simple coating method and apparatus that prevents bead collisions during coating and conserves coating materials. Summary of the Invention

[0006] To address the aforementioned technical problems of existing devices being complex, large-scale devices used in assembly line operations, low paint utilization due to spraying methods, and existing mixing devices not involving ball coating and having complex structures, this invention provides a perforated ball paint coating device, method, and application. The invention primarily utilizes the principle that during the rotation of the driven cylindrical surface, the upper balls are pressed downwards. Under the action of the elastic rope, the lower balls move upwards under the pressure of the elastic rope and the ball's compression. Furthermore, the friction between the balls causes them to continuously rotate. Under the influence of these multiple movements, paint is evenly coated onto the surface of the balls, thus completing the ball coating process.

[0007] The technical means employed in this invention are as follows:

[0008] A perforated ball bead paint coating device includes: a driving device, a container with an internal cavity, and a ball chain. The lower part of the driving device is connected to the upper part of the cavity, forming a movement space between the driving device and the cavity. The ball chain is mainly composed of several balls, and the ball chain coated with coating material is placed in the movement space. The driving device drives the ball chain to rotate continuously, so as to achieve uniform coating of coating material on the surface of the balls.

[0009] Furthermore, the driving device includes a handle, a cover, and a driving cylinder. The handle is installed above the cover, the cover is closed on the top of the container, and the driving cylinder is installed below the cover and inserted into the cavity of the container, forming the motion space between the driving cylinder and the cavity. The rotation of the driving cylinder is achieved by the handle, and during the rotation, the ball chain undergoes multiple movements under the action of the driving cylinder.

[0010] Furthermore, the outer diameter of the cover is the same as the outer diameter of the container; the driving cylinder is a cylinder with the diameter of its outer cylindrical surface being the same as the inner diameter of the container, and the bottom of the driving cylinder has an inclined surface that contacts the ball chain during movement.

[0011] Furthermore, the ball chain is a ring-shaped ball chain structure consisting of several balls linked together by an elastic structure, which is placed in a container after being twisted, folded, and coated with a coating material.

[0012] Furthermore, the handle is either manually driven or electrically driven.

[0013] Furthermore, the container is a cylindrical barrel with a chamfer, the cavity is cylindrical, and the chamfer is located at the bottom of the cavity.

[0014] Furthermore, the bottom slope of the driving cylinder is either a plane or a concave-convex curved surface.

[0015] Furthermore, the elastic structure is an elastic rope.

[0016] The present invention also provides a coating method for a perforated ball bead paint coating device, comprising the following steps:

[0017] Step 1: Thread the perforated beads into a chain using elastic cord;

[0018] Step 2: First, twist the ball chain into a figure-eight shape with the middle as the reference point;

[0019] Step 3: Fold the twisted ball chain from Step 2 in half to form the folded ball chain;

[0020] Step 4: Apply an appropriate amount of coating material to the folded ball chain from Step 3;

[0021] Step 5: Place the ball chain with the coating material into the container;

[0022] Step 6: Install the drive unit on the container in a position that adapts to the folding ball chain;

[0023] Step 7: Hold the handle and rotate the drive device; after the drive device has been rotating for a period of time, the coating material can be evenly applied to the surface of the balls in the ball chain.

[0024] The present invention also provides an application of a perforated ball bead paint coating device or a perforated ball bead paint coating method in the application of rust inhibitors to perforated ball beads, and in the grinding or rust removal of perforated ball beads.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] 1. The perforated ball bead paint coating device, method and application provided by the present invention, when the driving device rotates, the driving column will press the upper ball bead downward. Due to the action of the elastic rope, the lower ball bead will move upward under the pressure of the elastic rope and the ball extrusion. With the help of the friction between the balls, the balls will rotate continuously. Under the influence of multiple movements, the paint will be evenly coated on the surface of the ball bead, thus completing the ball bead coating.

[0027] 2. The perforated ball paint coating device, method and application provided by the present invention can prevent the balls from colliding with each other during coating and save coating materials.

[0028] 3. The perforated ball bead painting apparatus, method, and applications provided by this invention can be used for painting perforated ball beads with rust inhibitors when the paint is replaced with a rust inhibitor. When the paint is replaced with an abrasive material, this method can be used for grinding or removing rust from perforated ball beads. When the container is filled with liquid media such as paint, it can be used for media stirring.

[0029] In summary, the technical solution of this invention can solve the problems of existing devices being complex and large-scale devices used in assembly line operations; low paint utilization rate when using spraying methods; and existing mixing devices not involving ball coating and having complex structures.

[0030] Based on the above reasons, this invention can be widely promoted in the fields of paint coating and other related fields. Attached Figure Description

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0045] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0046] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0047] For ease of description, spatial relative terms such as "above," "over," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation besides the orientation of the device as described in the figures. For example, if the device in the figures is inverted, a device described as "above" or "above" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0048] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0049] This invention overcomes the shortcomings of existing technologies, providing a solution for small-batch coating of perforated beads under the premise that coating materials are precious and the beads must not collide during coating. Therefore, spraying or dip coating is unsuitable to avoid wasting coating materials. Electrodeposition is also unsuitable, as it is only suitable for water-soluble coating materials. Furthermore, both spraying and electrodeposition require complex equipment. Therefore, a simple coating method and apparatus are needed to prevent bead collisions during coating and to save coating materials.

[0050] This invention provides a method and apparatus for painting perforated beads with paint, see [link / reference]. Figure 3 The device includes a drive unit 1, a container 2, and a ball chain 3. The container 2 has a cavity inside, and the lower part of the drive unit 1 is connected to the upper part of the cavity, forming a movement space between them. The ball chain 3 is mainly composed of several balls, and the ball chain 3 coated with coating material is placed in the movement space. The drive unit 1 drives the ball chain 3 to rotate continuously, so that the coating material is evenly coated on the surface of the balls.

[0051] Preferably, container 2 is a cylindrical barrel with chamfered interior, see Figure 4The chamfer is located at the bottom of the cavity. Container 2 can also be other shapes with a cylindrical inner cavity and other chamfers, or have other devices to increase auxiliary radial thrust. Specifically, in this embodiment, container 2 has inner and outer cylindrical surfaces. "Other shapes" means that the outer surface of container 2 can be any other shape, while the inner surface remains cylindrical. The interior of container 2 has rounded corners, or it can have right angles. The purpose of the chamfer is to facilitate the cleaning of coating deposits at the bottom. The auxiliary radial thrust device can be a device that can extend several protrusions in the diameter direction to change the inner diameter of container 2. It can compress the upper ball chain, facilitating the downward movement of the upper ball chain, and can play the same role as the driving cylindrical surface 6, making the ball chain movement smoother.

[0052] Preferably, the drive device 1 is described below. Figure 5 The device consists of a handle 4, a cover 5, and a drive cylinder 6. The handle 4 is mounted above the cover 5 and is used to rotate the drive device 1. The cover 5 is placed on top of the container 2, and the drive cylinder 6 is mounted below the cover 5 and inserted into the cavity of the container 2, forming the aforementioned motion space between the drive cylinder 6 and the cavity. The rotation of the drive cylinder 6 is achieved by the handle 4, and during the rotation, the ball chain 3 undergoes multiple movements under the action of the drive cylinder 6. The outer diameter of the cover 5 is the same as that of the container 2, and the cylindrical surface of the drive cylinder 6 is the same as that of the container 2. The bottom slope of the drive cylinder 6 is a specific curved surface that cooperates with the ball chain 3. This bottom slope can be a plane, and it contacts the ball chain 3 during movement. The bottom slope of the drive cylinder 6 can also be replaced by a simpler or more complex concave-convex curved surface. If the bottom slope is a straight surface, it will only contact one ball according to the geometric relationship; if it is a curved surface, the surface can be set according to the diameter of the ball, and it can contact at least two balls to achieve better driving effect and make the movement of the entire ball chain smoother. The driving column 6 can also be equipped with a paint adsorption component to ensure a continuous supply of paint. For example, a sponge-like material that can adsorb paint can be pasted on the inclined surface of the driving column 6 to ensure a continuous supply of paint. For a more complex case, an atomic stamping method can be used to preserve and continuously apply the paint.

[0053] Preferably, the ball chain 3 is a ring-shaped ball chain structure composed of several balls linked together by an elastic structure. After being twisted, folded, and coated with a coating material, it is placed in the container 2. The elastic structure can be an elastic rope, which is a product that provides elasticity, or it can be replaced with other products that provide elasticity.

[0054] Preferably, the handle 4 of the drive device 1 can be replaced by other means of providing rotational motion to the drive device, such as other types of handles and adapter electric drive devices. Specifically, the handle 4 can be manually driven or electrically driven. When manually driven, the cover 5 can be driven to rotate along with the drive cylinder 6 by manually rotating the handle 4. In this case, the handle 4 can be eccentrically positioned relative to the center of the cover 5, or it can be positioned at the edge of the cover 5, which is more conducive to achieving rotation. When electrically driven, a motor can be connected to the handle 4. The motor can be connected to the cover 5, and the drive cylinder 6 can be rotated by driving the cover 5 to rotate. Alternatively, the motor can be mounted on the cover 5, and the motor shaft can be connected to the drive cylinder 6, directly driving the drive cylinder 6 to rotate. In this case, the handle 4 is located at the center of the cover 5.

[0055] The present invention provides a method for applying paint to perforated spherical beads, the specific steps of which are as follows:

[0056] Step 1: Thread the perforated beads into a ball chain 3 using elastic cord, see... Figure 6 For clarity, the elastic rope is not shown in the diagram.

[0057] Step 2: Twist the ball chain 3 in the middle for the first time into a figure-eight shape, see... Figure 7 .

[0058] Step 3: Fold the twisted ball chain 3 in half to form the folded ball chain 3, see... Figure 8 .

[0059] Step 4: Apply an appropriate amount of coating material to the ball chain.

[0060] Step 5: Place the ball chain with the coating material into container 2.

[0061] Step 6: Install the drive unit 1 onto the container 2 in a position that corresponds to the folding ball chain. See details below. Figure 1 .

[0062] Step 7: Hold the handle 4 and rotate the drive device 1 in the following direction: Figure 9 As shown.

[0063] After the drive device 1 rotates for a period of time, the surface of the ball chain 3 can be evenly coated with coating material. The principle is as follows:

[0064] When the drive device 1 rotates, the drive column 6 will press the upper ball down. Due to the action of the elastic rope, the lower ball will move upward under the pressure of the elastic rope and the ball's compression. With the help of the friction between the balls, the balls will rotate continuously. Under the influence of multiple movements, the paint will be evenly coated on the surface of the balls, completing the coating of the balls.

[0065] The key technical points and protected points of this invention are: 1. A folding scheme for the elastic connection of the ball and bead. 2. A driving scheme adapted to the shape of the folding scheme for the elastic connection of the ball and bead chain, i.e., driving device 1. 3. A method and apparatus for painting perforated ball and bead. 4. When the paint is replaced with a rust inhibitor, this painting method can be used for painting perforated ball and bead with a rust inhibitor. 5. When the paint is replaced with an abrasive material, this painting method can be used for polishing or removing rust from perforated ball and bead. 6. When the container 2 is filled with liquid media such as paint, it can be used for media stirring.

[0066] Example 1

[0067] Take a ball chain 3 consisting of 17 beads as an example:

[0068] Step 1: Thread the perforated beads into a ball chain 3 using elastic cord.

[0069] Step 2: Twist the ball chain 3 in the middle for the first time to form an "8" shape.

[0070] Step 3: Fold the twisted ball chain 3 in half to form the folded ball chain 3.

[0071] Step 4: Apply an appropriate amount of coating material to the folded ball chain. The coating material is paint.

[0072] Step 5: Place the ball chain with the coating material into container 2.

[0073] Step 6: Install the drive unit 1 onto the container 2 in a position that corresponds to the folding ball chain. See details below. Figure 1 .

[0074] Step 7: Hold the handle 4 and rotate the drive device 1. After the drive device 1 has been rotating for a period of time, the surface of the ball chain 3 can be evenly coated with paint.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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; and these 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 the present invention.
