Description

Technical Field

[0001] This utility model relates to the field of furniture manufacturing technology, specifically a portable paint touch-up device for furniture manufacturing. Background Technology

[0002] Furniture touch-up painting is the repair of damage to the structure or finish of furniture. These repairs cover damage to various parts of furniture in the following categories: solid wood furniture, panel furniture, upholstered furniture, rattan furniture, bamboo furniture, metal furniture, and steel-wood furniture.

[0003] Existing paint touch-up devices lack a mixing mechanism. Workers typically mix the paint manually before pouring it into the device. This manual mixing is not only inefficient, resulting in low paint preparation efficiency, but also leads to paint waste when the mixed paint is poured into the touch-up device.

[0004] To address the aforementioned problems, existing technologies offer a solution. For example, patent publication number CN220143807U discloses a portable paint touch-up device for furniture manufacturing, comprising a hollow housing. The housing has wheels at each of the four corners of its lower surface. The upper surface of the housing has a feed inlet communicating with the interior. A first thread is formed on the outer surface of the feed inlet, and a sealing cap is fitted onto this threaded outer surface. A motor is fixedly connected to the upper surface of the housing, and the motor's output shaft rotates through the housing. In this portable paint touch-up device for furniture manufacturing, when the motor is started, the output shaft rotates... The synchronous rotation of the rotating rod drives the mixing rod to rotate, which in turn mixes and stirs the paint liquid inside the box. By using the rotating rod to drive the mixing rod to mix and stir the paint liquid, the paint liquid can be stirred more evenly, saving manpower and improving the mixing efficiency, thereby improving the painting efficiency. Existing devices generate a lot of bubbles on the paint surface when stirring the paint. These bubbles exist inside the paint, and when they are sprayed onto the furniture along with the paint, they will burst due to collision. The bursting of bubbles will cause uncontrollable paint splattering, which can easily lead to poor painting results on the furniture.

[0005] Therefore, a portable paint touch-up device for furniture manufacturing is proposed. Utility Model Content

If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0028] Reference Figures 1 to 7 A portable paint touch-up device for furniture manufacturing includes a mixing drum 1 with a filling port and a connection port at its top. It also includes a servo motor 2, a rotating mechanism 3, a mixing rod 4, a rotating roller 5, a connecting mechanism 6, and a striking rod 7. The servo motor 2 is connected to the mixing drum 1 via a coupling or other suitable connection method to ensure reliable power transmission. Both the rotating mechanism 3 and the connecting mechanism 6 are connected to the servo motor 2. The mixing rod 4 and the rotating roller 5 are both connected to the rotating mechanism 3. The mixing rod 4 is made of stainless steel with a smooth surface to reduce paint adhesion. The shape and distribution of the mixing rod 4 are designed according to the size of the mixing drum 1 and the uniformity requirements of paint mixing. Generally, it is evenly distributed along the circumference and has different mixing blades along its length to improve the mixing effect. The mixing rod 4 and the rotating rod 31 are fixed together by welding or other reliable connection methods. The rotating roller 5 is installed inside the mixing drum 1, its position corresponding to that of the mixing rod 4. The rotating roller 5 is connected to the rotating mechanism 3. Through differential rotation with the stirring rod 4, it stirs the paint and removes air bubbles. The striking rod 7 is connected to the connecting mechanism 6. When the servo motor 2 starts, the rotating mechanism 3 controls the stirring rod 4 and the rotating roller 5 to rotate at different speeds to stir the paint. When the rotating mechanism 3 is running, the connecting mechanism 6 runs synchronously and controls the striking rod 7 to intermittently strike the stirring drum.

[0029] As one embodiment of this utility model, refer to Figure 2 The rotating mechanism 3 includes a rotating rod 31, a rectangular frame 32, a horizontal gear 33, and an internal gear 34. The rotating rod 31 is connected to the servo motor 2. The stirring rod 4 and the rectangular frame 32 are both connected to the rotating rod 31. The horizontal gear 33 is connected to the rectangular frame 32. The internal gear 34 cooperates with the horizontal gear 33. The gear ratio between the horizontal gear 33 and the internal gear 34 is 1:4. With the above settings, the rotating roller 5 can rotate at a slower speed than the stirring rod 4, thereby removing the bubbles generated by stirring.

[0030] As one embodiment of this utility model, refer to Figures 3 to 6The connecting mechanism 6 includes a drive gear 61, a horizontal rack 62, a movable rod 63, a telescopic spring 64, teeth 65, a guide block 66, a guide rod 67, a return spring 68, a vertical rod 69, a limit block 610, a limit rod 611, a buffer spring 612, and an impact unit 613. The drive gear 61 is connected to the servo motor 2. The tooth profile and size of the drive gear 61 are designed according to the matching requirements with the horizontal rack 62 to ensure that the power of the motor can be accurately transmitted to the horizontal rack 62. The horizontal rack 62 matches the drive gear 61. The movable rod 63 meshes with the drive gear 61 and moves linearly under the drive of the drive gear 61. Both the movable rod 63 and the telescopic spring 64 are connected to the horizontal rack 62. The tooth 65 is connected to the movable rod 63. The movable rod 63 moves linearly under the drive of the horizontal rack 62, simultaneously driving the tooth 65 and other components to move. The telescopic spring 64 is mounted on the movable rod 63, and its function is to provide buffering and restoring force when the horizontal rack 62 moves, ensuring the stable operation of the connecting mechanism 6. Through the above arrangement, the cyclic movement of the horizontal rack 62 can be realized. The guide block 66... Connected to the horizontal rack 62, the guide rod 67 and the return spring 68 are connected to the guide block 66. The guide block 66 cooperates with the guide groove 615 inside the stirring drum 1 to ensure the accuracy and stability of the horizontal rack 62 during linear motion. The guide rod 67 is installed in the guide groove 615 to provide guidance for the linear motion of the horizontal rack 62. At the same time, the return spring 68 is installed for the return of the horizontal rack 62. After the horizontal rack 62 moves to a certain position, the return spring 68 provides a reverse force, enabling it to return to the initial position and achieve periodic motion. The vertical rod 69 cooperates with the horizontal rack 62. The limiting block 610 and the impact unit 613 are both connected to the vertical rod 69. The limiting rod 611 and the buffer spring 612 are both connected to the limiting block 610. The horizontal rack 62 and the vertical rod 69 are both provided with inclined parts 614, which are set at 45 degrees. The stirring drum 1 is provided with a guide groove 615 and a limiting groove 616. The guide block 66, the guide rod 67 and the reset spring 68 are all installed in the guide groove 615. The limiting block 610, the limiting rod 611 and the buffer spring 612 are all installed in the limiting groove 616.

[0031] As one embodiment of this utility model, refer to Figure 7The impact unit 613 includes a vertical rack 6131, a connecting gear 6132, a connecting rod 6133, a connecting spring 6134, and a fixing sleeve 6135. The vertical rack 6131 is connected to the vertical rod 69, and the connecting gear 6132 meshes with the vertical rack 6131. ​​The vertical rack 6131 and the connecting gear 6132 mesh with each other. The movement of the vertical rod 69 drives the connecting gear 6132 to rotate. The connecting rod 6133 meshes with the connecting gear 6132, and the connecting spring 6134 is connected to the connecting rod 6133. The fixing sleeve 6135 is connected to the connecting spring 6134. The connecting spring 6134 provides buffering and restoring force for the swing of the connecting rod 6133, ensuring the smoothness of the striking action. The fixing sleeve 6135 is connected to the connecting spring 6134, providing a buffering and restoring force for the swing of the connecting rod 6133, ensuring the smoothness of the striking action. The swing of 133 provides support and limit function. The connecting rod 6133 includes a toothed part 61331, a flat part 61332 and an impact part 61333. The toothed part 61331 is engaged with the connecting gear 6132. The lengths of the toothed part 61331, the flat part 61332 and the impact part 61333 are the same. The toothed part 61331 is engaged with the connecting gear 6132. The flat part 61332 plays a connecting and transmission role. The impact part 61333 is used to strike the mixing drum. The striking rod 7 is made of stainless steel and its end is wrapped with rubber or plastic to reduce damage to the mixing drum during striking. The striking rod 7 is connected to the impact unit 613 of the connecting mechanism 6. Under the action of the impact unit 613, the mixing drum is struck intermittently to further eliminate air bubbles in the paint.

[0032] Working principle: When in use, the user moves the mixing drum 1 to the processing area, then adds paint into the mixing drum through the filling port, and then starts the servo motor 2. The servo motor 2 drives the rectangular frame 32 and the mixing rod 4 to rotate through the rotating rod 31. When the mixing rod 4 rotates, it can stir and mix the paint. When the rectangular frame 32 rotates, it can drive the horizontal gear 33 and the internal gear 34 to mesh. When the horizontal gear 33 rotates, it can drive the rotating roller 5 to rotate at a slower speed than the mixing rod 4, thereby eliminating the air bubbles generated by stirring.

[0033] When the servo motor 2 starts, the drive gear 61 drives the horizontal rack 62 to move horizontally. After the horizontal rack 62 moves a certain distance, the teeth 65 mesh with the drive gear 61, thus preventing the horizontal rack 62 from continuing to move horizontally. When the teeth 65 mesh with the drive gear 61, they control the movable rod 63 to enter the horizontal rack 62, and at the same time compress the telescopic spring 64. When the horizontal rack 62 moves, it can drive the guide block 66 to move on the guide rod 67, and at the same time compress the return spring 68. When the horizontal rack 62 moves, it can squeeze the inclined part 614 of the vertical rod 69 through the inclined part 614. Under the action of pressure, the vertical rod 69 is controlled to move downward. When the vertical rod 69 moves downward, it drives the connecting gear 6132 to rotate through the vertical rack 6131. ​​When the connecting gear 6132 rotates, it drives the flat part 61332 and the impact part 61333 to move in the fixed sleeve 6135 through the tooth part 61331. At the same time, it squeezes the connecting spring 6134. At this time, the striking rod 7 separates from the stirring cylinder 1.

[0034] When tooth 65 disengages from drive gear 61, the horizontal rack 62 and vertical rod 69 are reset under the action of reset spring 68 and buffer spring 612, thereby controlling the vertical rack 6131 to disengage from connecting gear 6132. In the event of loss of power, connecting spring 6134 controls the striking rod 7 to move towards stirring drum 1 and strike, which can accelerate the elimination of bubbles.

[0035] Although the embodiments of this utility model have been described in detail with reference to the accompanying drawings, those skilled in the art can make changes, modifications, substitutions and variations to these embodiments without departing from the principles and spirit of this utility model. The appended claims and their equivalents define the scope of this utility model.
