DETAILED DESCRIPTION

[0033] The following will be combined with the drawings to further illustrate the present application. Figs. 1-3 The present application will be further described in detail.

[0034] Embodiment one, referring to Figs. 1-3 In the present embodiment, in order to solve the problem that the existing device needs to be turned over by the operator after the wood is sprayed on one side, and then the other side of the wood can be sprayed, so that the wood is sprayed more troublesome, the present application discloses a static powder spraying device for the surface of furniture wood board,

[0035] The system includes a powder spraying mechanism 100, which includes a housing 101. The outer wall of the housing 101 is provided with a transparent window 101a. The inner bottom wall of the housing 101 is provided with a first sliding groove 101b. A first drive rod 102 is rotatably disposed in the first sliding groove 101b. The side wall of the housing 101 is provided with an opening 101c. The transparent window 101a allows the operator to view the powder spraying effect on the furniture wood panels. The opening 101c allows the shelf 103 to move the furniture wood panels into the housing 101. The first sliding groove 101b facilitates the assembly of the first drive rod 102.

[0036] The inner bottom wall of the housing 101 is provided with a first drive rod 102, and a shelf 103 is movably sleeved on the first drive rod 102. By inserting the furniture board into the shelf 103, the first drive rod 102 is activated to facilitate the movement of the furniture board into the housing 101 through the shelf 103.

[0037] The inner wall of the housing 101 is provided with a second drive rod 104, and a powder spraying gun 105 is movably sleeved on the second drive rod 104. By activating the second drive rod 104, it is easy to control the movement of the powder spraying gun 105 and spray powder onto the furniture wood panels.

[0038] Both the first drive rod 102 and the second drive rod 104 are provided with triangular thread. The outer wall of the housing 101 is fixedly provided with a first motor 101d corresponding to the first drive rod 102 and the second drive rod 104. The rotating shafts of the two first motors 101d pass through the housing 101 and are fixedly connected to one end of the first drive rod 102 and the second drive rod 104. The first motors 101d facilitate the rotation of the first drive rod 102 and the second drive rod 104. The first drive rod 102 facilitates the movement of the shelf 103, thereby facilitating the movement of the furniture board into the housing 101 for powder spraying. The second drive rod 104 facilitates the movement of the powder spraying gun 105, thereby powder spraying the furniture board.

[0039] The flipping mechanism 200 includes an electric push rod 201, and a rotating cylinder 202 is provided at the extended end of the electric push rod 201. The electric push rod 201 facilitates the up-and-down movement of the rotating cylinder 202.

[0040] The bottom of the rotating cylinder 202 is equipped with a clamping member 204 via a one-way bearing 203. When the rotating cylinder 202 rotates, the one-way bearing 203 is locked, and then the clamping member 204 and the furniture board rotate through the one-way bearing 203, thereby turning the furniture board over. When the rotating cylinder 202 rotates in the opposite direction, the one-way bearing 203 is unlocked, and at this time the clamping member 204 and the furniture board remain stationary.

[0041] A guide rod 205 is fixedly installed on the inner top wall of the housing 101. The guide rod 205 slides with the outer wall of the rotating drum 202. The rotating drum 202 can be pulled upward by the electric push rod 201. At this time, the guide rod 205 cooperates with the outer wall of the rotating drum 202, thereby facilitating the control of the rotation of the rotating drum 202.

[0042] The specific working principle is as follows: First, the furniture board is inserted into the shelf 103. Then, the first drive rod 102 is activated to move the shelf 103 and the furniture board into the housing 101. Then, the electric push rod 201 pushes the rotating cylinder 202 and the clamping member 204 to move down and clamps and fixes the furniture board. Then, the electric push rod 201 pulls the rotating cylinder 202, the clamping member 204 and the furniture board to move up to the position corresponding to the powder spraying gun 105. Then, the second drive rod 104 is activated to control the movement of the powder spraying gun 105 and spray the furniture board with powder.

[0043] After one side of the furniture board is powder-coated, the electric push rod 201 pulls the rotating cylinder 202 to continue moving upward. At this time, the guide rod 205 cooperates with the outer wall of the rotating cylinder 202 to make the rotating cylinder 202 rotate. At this time, the one-way bearing 203 is in a locked state, thereby driving the clamping part 204 to rotate and flip the furniture board through the one-way bearing 203.

[0044] Then, the electric push rod 201 pushes the rotating cylinder 202 to move down. At this time, the guide rod 205 drives the rotating cylinder 202 to rotate in the opposite direction. At this time, the one-way bearing 203 is in the unlocked state. At this time, the clamping part 204 remains stationary with the furniture board and moves down to the position corresponding to the powder spraying gun 105. Then, the powder spraying gun 105 sprays powder on the other side of the furniture board.

[0045] Example 2, refer to Figs. 1-3 In this embodiment, to address the issue of increased costs caused by existing devices having multiple powder spraying mechanisms that spray powder onto both sides of furniture wood panels, based on the same concept as in Embodiment 1, this electrostatic powder spraying device for furniture wood panels further includes:

[0046] The powder spraying gun 105 includes a movable plate 105a and a gun body 105b. The movable plate 105a is threaded onto the second drive rod 104, and the gun body 105b is fixedly mounted on the outer wall of the movable plate 105a. When the second drive rod 104 rotates, the movable plate 105a drives the gun body 105b to move along the axial direction of the second drive rod 104, thereby facilitating all-round powder spraying of furniture wood panels through the gun body 105b.

[0047] A movable block 103a is fixedly installed on the bottom surface of the shelf 103. The movable block 103a is located in the first slide groove 101b and threaded onto the first drive rod 102. A slot 103b is opened on the top surface of the shelf 103. A sealing plate 103c is fixedly installed on the end of the shelf 103 facing the opening 101c. The sealing plate 103c is movably inserted into the inner wall of the opening 101c. When the first drive rod 102 rotates, it causes the movable block 103a to slide along the inner wall of the first slide groove 101b. At the same time, the movable block 103a drives the shelf 103 to move. The slot 103b makes it easy for the operator to insert the furniture board into the shelf 103. When the shelf 103 moves the furniture board into the housing 101, the sealing plate 103c makes it easy to seal the opening 101c.

[0048] The upper end of the rotating drum 202 is connected to the extended end of the electric push rod 201 through a ball bearing. The ball bearing facilitates the rotation of the rotating drum 202 when the guide rod 205 is inserted into the outer wall of the rotating drum 202.

[0049] The outer wall of the rotating drum 202 is provided with an outer spiral groove 202a. One end of the guide rod 205 is fixedly connected to the inner top wall of the housing 101, and the other end of the guide rod 205 is slidably engaged with the inner wall of the outer spiral groove 202a. When the guide rod 205 is inserted into the outer spiral groove 202a, it causes the rotating drum 202 to rotate. When the rotating drum 202 rotates, the one-way bearing 203 is in a locked state. Then, the one-way bearing 203 drives the clamping member 204 and the furniture board to rotate, thereby realizing the flipping of the furniture board. When the rotating drum 202 rotates in the opposite direction, the one-way bearing 203 is in an unlocked state. At this time, the clamping member 204 and the furniture board remain stationary.

[0050] The specific working principle is as follows: the rotating drum 202 drives the one-way bearing 203, the clamping part 204 and the furniture board to rotate and flip the surface. Then, the electric push rod 201 pushes the rotating drum 202 and the furniture board to move down for powder spraying. Therefore, when the furniture board is powder sprayed, only one powder spraying gun 105 housing is set in the device, thereby reducing the cost of the device.

[0051] Example 3, refer to Fig. 3 Based on the same concept as in Embodiment 1 above, the electrostatic powder coating device for the surface of furniture wood panels further includes:

[0052] The clamping member 204 includes a grooved plate 204a, in which a double threaded rod 204b is rotatably disposed. The threads at both ends of the double threaded rod 204b are in opposite directions. A second motor 204c is fixedly disposed at one end of the grooved plate 204a. The rotating shaft of the second motor 204c passes through the grooved plate 204a and is fixedly connected to one end of the double threaded rod 204b. Both ends of the double threaded rod 204b are threaded with clamping plates 204d. A connecting rod 204e is fixedly disposed on the top surface of the grooved plate 204a. The connecting rod 204e is fixedly inserted into the inner side of the one-way bearing 203.

[0053] The specific working principle is as follows: the second motor 204c drives the double threaded rod 204b to rotate, which facilitates the contraction or opening of the two clamping plates 204d. When the two clamping plates 204d contract, they can clamp and fix the furniture board. Then, the electric push rod 201 can pull the rotating cylinder 202, the grooved plate 204a and the height position of the furniture board to adjust. The two clamping plates 204d can clamp furniture boards of different specifications.

[0054] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
