Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically a wood spraying device. Background Technology

[0002] Timber, broadly referring to wooden materials used in civil and industrial construction, can generally be divided into coniferous and broadleaf timber. Timber processing refers to the process of treating timber as raw material through mechanical or chemical methods while preserving its original basic characteristics. One common timber processing step is painting planks to improve the appearance and protective properties of the wood products. However, traditional timber painting equipment typically involves reciprocating the wood horizontally, then painting one side of the wood under the action of a spray nozzle. After painting one side, the wood is left to dry before flipping it over for painting the other side. This process is inconvenient for flipping the wood, thus affecting the processing effect. Therefore, we propose a new timber painting device. Utility Model Content

[0003] This invention provides a wood spraying device that solves the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a wood spraying device, comprising a circular frame and wood, a support column fixedly connected to the top of the circular frame, a top plate fixedly connected to the top of the support column, a storage box fixedly connected to the top plate, an extension ring plate fixedly connected to the bottom of the circular frame, and two sets of staggered clamping and flipping mechanisms connected to the circular frame. Each clamping and flipping mechanism includes a rectangular frame movably connected to the circular frame, and the outer side of the circular frame is circular and fitted with an external gear ring. The external gear ring meshes with a gear, which meshes with the outer side of the rectangular frame. The gear is connected to the extension ring plate via a pin. The gears on the two sets of clamping and flipping mechanisms drive the rectangular frame in opposite directions under the transmission of the external gear ring.

[0005] Optionally, a first motor is fixedly installed at the bottom of the extended ring plate, and the output shaft of the first motor is fixedly connected to the bottom end of one of the gears.

[0006] Optionally, a paint spraying pipe is fixedly connected to the middle of the bottom of the top plate. The paint spraying pipe is connected to the storage box. Multiple spray nozzles are fixedly connected to the paint spraying pipe, and a hot air blower for drying wood is fixedly connected to the top of the top plate.

[0007] Optionally, the clamping and flipping mechanism further includes a rotating cylindrical base, a clamping arc plate, an abutment plate, and triangular protrusions. The rotating cylindrical base is circularly and movably fitted inside a rectangular frame, with one end of the rotating cylindrical base near the wood extending out of the rectangular frame. Two clamping arc plates are connected to one end of the rotating cylindrical base via a pivot pin. An abutment plate is movably connected to the middle of one end of the rotating cylindrical base. Triangular protrusions are fixedly connected to both sides of the abutment plate extending into the rotating cylindrical base. The triangular protrusions can contact one end of the clamping arc plate, and can push the clamping arc plate to rotate when the triangular protrusions move into the rotating cylindrical base.

[0008] Optionally, a second spring is fixedly connected to one end of the abutment plate that extends into the rectangular frame, and one end of the second spring is fixed to the rotating cylindrical base.

The clamping and flipping mechanism allows the wood to be flipped for painting, ensuring complete painting and making the painting process more convenient. In this wood painting device, the abutment plate moves when it contacts the wood, pushing a triangular protrusion. This protrusion then rotates the clamping arc plate, allowing it to clamp the wood automatically, thus making the device more convenient to use. Attached Figure Description

[0016] 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.

[0017] Please see Figures 1 to 3 This utility model provides a wood spraying device, including a circular frame 1 and a piece of wood 5. A support column 2 is fixedly connected to the top of the circular frame 1, and a top plate 3 is fixedly connected to the top of the support column 2. A storage box 4 is fixedly connected to the top plate 3. An extension ring plate 8 is fixedly connected to the bottom of the circular frame 1. Two sets of staggered clamping and flipping mechanisms are connected to the circular frame 1, which can alternately clamp the wood 5, thereby spraying paint on the clamped areas, resulting in more comprehensive painting. The clamping and flipping mechanism includes a rectangular frame 7, which is movably connected to the circular frame 1. Under the constraint of the circular frame 1, the rectangular frame 7 can move along a fixed direction. The outer side of frame 1 is circular and fitted with an external gear ring 10. The external gear ring 10 can rotate in a fixed position on the circular frame 1. The external gear ring 10 meshes with a gear 9. Under the transmission of the external gear ring 10, the gear 9 can rotate. The gear 9 meshes with the outer side of the rectangular frame 7. Under the transmission of the gear 9, the rectangular frame 7 can move. The gear 9 is connected to the extension ring plate 8 through a shaft pin, forming a hinge structure with the shaft pin as the pivot. This allows the gear 9 to rotate in a fixed position on the extension ring plate 8. The gears 9 on the two sets of clamping and flipping mechanisms drive the rectangular frame 7 in opposite directions under the transmission of the external gear ring 10. This allows the two sets of clamping and flipping mechanisms to alternately clamp the wood 5.

[0018] Please see Figures 1 to 3 A first motor 12 is fixedly installed at the bottom of the extension ring plate 8. The output shaft of the first motor 12 is fixedly connected to the bottom end of one of the gears 9. Under the drive of the output shaft of the first motor 12, the gear 9 can rotate. The first motor 12 is existing technology and will not be described in detail here.

[0019] Please see Figures 1 to 3 A paint spraying pipe 11 is fixedly connected to the middle of the bottom of the top plate 3. The paint spraying pipe 11 is connected to the storage box 4. Multiple spray nozzles are fixedly connected to the paint spraying pipe 11. Under the action of the paint spraying pipe 11, the wood 5 can be painted. A hot air blower 6 that can dry the wood 5 is fixedly connected to the top of the top plate 3. Under the action of the hot air blower 6, the drying of the paint surface can be accelerated, thereby reducing the processing time.

[0020] Please see Figures 1 to 5 The clamping and flipping mechanism also includes a rotating cylindrical base 13, clamping arc plates 14, abutment plates 15, and triangular protrusions 16. The rotating cylindrical base 13 is circularly and movably fitted inside the rectangular frame 7. The rotating cylindrical base 13 can rotate in a fixed position within the rectangular frame 7. One end of the rotating cylindrical base 13 near the wood 5 extends out of the rectangular frame 7, and two clamping arc plates 14 are connected to one end of the rotating cylindrical base 13 by a pivot pin, forming a hinge structure with the pivot pin as the pivot. This allows the clamping arc plates 14 to rotate in a fixed position on the rotating cylindrical base 13. A contact plate 15 is movably connected to the middle of one end of the cylindrical base 13. The contact plate 15 can move along a fixed trajectory on the rotating cylindrical base 13. Triangular protrusions 16 are fixedly connected to both sides of the contact plate 15 inside the rotating cylindrical base 13. Driven by the contact plate 15, the triangular protrusions 16 can move and contact one end of the clamping arc plate 14. Under the push of the triangular protrusions 16, the clamping arc plate 14 can rotate to clamp the wood 5. When the triangular protrusions 16 move into the rotating cylindrical base 13, they can push the clamping arc plate 14 to rotate.

[0021] Please see Figures 1 to 5 A second spring 18 is fixedly connected to one end of the abutment plate 15 that extends into the rectangular frame 7. One end of the second spring 18 is fixed to the rotating cylindrical base 13. Under the action of the elastic force of the second spring 18, the abutment plate 15 can automatically reset. A first spring 17 is fixedly connected to the outer side of one end of the clamping arc plate 14 that extends into the rotating cylindrical base 13. The first spring 17 is fixed to the rotating cylindrical base 13. Under the action of the elastic force of the first spring 17, the clamping arc plate 14 can automatically reset.

[0022] Please see Figures 1 to 5 A second motor 19 is fixedly connected inside the rectangular frame 7. The output shaft of the second motor 19 is fixedly connected to one end of the rotating cylindrical base 13 that extends into the rectangular frame 7. Driven by the output shaft of the second motor 19, the rotating cylindrical base 13 can rotate, thereby allowing the wood 5 held by the clamping arc plate 14 to rotate and flip. The second motor 19 is existing technology and will not be described in detail here.

[0023] In summary, when this wood spraying device is in use, the output shaft of the first motor 12 drives the gear 9 to rotate, which in turn causes the external gear ring 10 to rotate. Driven by the external gear ring 10, the gear 9 rotates, causing a set of rectangular frames 7 to move towards the wood 5, allowing the abutment plate 15 to contact the wood 5 and move. Driven by the abutment plate 15, the triangular protrusion 16 moves, and the movement of the triangular protrusion 16... The movement causes the clamping arc plate 14 to rotate, thereby clamping the wood 5. Then, driven by the output shaft of the second motor 19, the clamping arc plate 14 clamps the wood 5 and flips it. Then, under the action of the paint spray pipe 11, it is sprayed with paint, and under the action of the hot air blower 6, it can be dried quickly. Then, under the transmission of the gear 9, another set of clamping and flipping mechanisms clamps the wood 5, and this set of clamping and flipping mechanisms releases the clamping, and then the clamped area is sprayed with paint.
