Description

Technical Field

[0001] The invention relates to the technical field of furniture processing, and in particular to a plate painting device for processing wooden furniture. Background Art

[0002] In the field of furniture, with the advancement of technology, the materials used have become more diverse, but wooden furniture is still loved by the majority of people because of its more beautiful and environmentally friendly characteristics. However, in order to improve the service life and aesthetics of wooden furniture, the boards used for wooden furniture processing need to be painted, and in furniture production, the painting of boards is gradually becoming mechanized.

[0003] However, the existing wooden furniture processing board painting equipment still has the following defects during use:

[0004] 1. In the process of mechanical and automated painting of the plate, the plate is often driven to rotate to achieve full painting. However, in the process of plate rotation, the nozzle of the traditional painting equipment is fixed. Therefore, during the rotation of the plate, the distance between the nozzle and the spraying surface of the plate will change, which will cause uneven spraying and reduce the effect of painting.

[0005] 2. During the painting process, the existing painting equipment uses a large-area spraying method for comprehensive painting, and cannot be adjusted intermittently according to the size of the board and the angle of rotation. It is easy to cause waste of paint and spray the narrow edge of the board. It is easy to cause blockage of the installation grooves and connection holes reserved for the board, affecting the normal subsequent furniture assembly. Summary of the invention

[0006] The purpose of the present invention is to solve the problem that the above-mentioned nozzle and the spraying surface of the board cannot maintain a consistent distance, which leads to uneven spraying, and the large-area spraying method easily causes waste of paint, and it is easy to cause blockage of the installation grooves and connecting holes reserved for the board, affecting the normal subsequent furniture assembly. The present invention provides a board painting equipment for processing wooden furniture.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] A board painting equipment for processing wooden furniture comprises a body, a paint hood is slidably connected to the top of the body, a turntable is symmetrically rotatably connected to the front and rear sides of the inside of the paint hood, a motor is fixedly installed on the front side of the paint hood, the motor is transmission-connected to the turntable located on the front side, and then drives the front turntable to rotate, a fixing seat is fixedly installed on the adjacent sides of the front and rear turntables, a board is fixedly installed between the fixing seats, fixing cylinders are symmetrically fixedly installed on the front and rear sides of the top of the paint hood, and a fixing frame is fixedly installed between the fixing cylinders on the front and rear sides of the top of the paint hood.

[0009] A rotary paint spraying assembly is arranged between the front and rear turntables, and the rotary paint spraying assembly is used to spray paint evenly and equidistantly on the surface of the plate during the rotation of the plate. A paint supply assembly is arranged between the fixed cylinders and above the rotary paint spraying assembly, and the paint supply assembly is used for accurate and intermittent delivery of paint during the painting process.

[0010] Furthermore, the rotary paint spraying assembly includes a limiting ring, the adjacent bottom ends of the front and rear turntables are fixedly connected to the limiting ring, the adjacent side of the front and rear limiting rings is provided with a mounting seat, and the side of the front and rear mounting seats away from each other is provided with a roller, the number of rollers at a single mounting seat is four, and they are symmetrically wrapped on both sides of the limiting ring, so that during the rotation of the limiting ring, the rollers can be driven to slide on both sides of the limiting ring, and a lifting column is connected to the limiting rotation on the side of the top of the front and rear mounting seats away from each other, and a mounting arch plate is fixedly installed between the adjacent sides of the top of the front and rear mounting seats, a paint outlet pipe is fixedly installed on the inner side of the mounting arch plate, the paint outlet pipe outlet faces downward, and the tops are connected to each other, a spray head is fixedly installed at the outlet of the bottom of the paint outlet pipe, and the outer limit rotation connection of the top of the paint outlet pipe is connected to a connecting pipe, and the bottom of the connecting pipe is connected to the inside of the paint outlet pipe, so that the bottom of the connecting pipe can rotate around the top of the paint outlet pipe and can also transport paint to the paint outlet pipe.

[0011] Furthermore, a slide groove is provided inside the mounting seat, and a connecting block is connected to the internal limiting sliding connection of the slide groove, and an elastic curved plate is fixedly connected between the adjacent ends of the left and right connecting blocks and the inner wall of the mounting seat. The connecting block and the roller are connected to the limiting rotation, so that the roller can rotate and move, and through the action of the elastic curved plate, when passing through the arcs on both sides of the limiting ring, the connecting block can drive the roller to open or contract to pass through the arc edge of the limiting ring.

[0012] Furthermore, the top of the lifting column extends upward to the interior of the fixed cylinder, and a protrusion is provided on the top of the lifting column, which is limited and slidably connected with the inner cavity of the fixed cylinder, and when the limiting ring rotates to a horizontal state with the turntable, the protrusion on the top of the lifting column slides to the bottom of the inner cavity of the fixed cylinder. Therefore, when the limiting ring starts to rotate from the horizontal state, the lifting column and the mounting seat cannot move downward due to the limitation of the inner cavity of the fixed cylinder, thereby driving the lifting column and the mounting seat to move upward.

[0013] Furthermore, the fixed seat is composed of a hydraulic rod and an extrusion seat, the hydraulic rod is fixed at one adjacent end of the front and rear turntables, the extrusion seat is fixedly installed at one adjacent end of the hydraulic rod, and the hydraulic rod and the extrusion seat are located at the center of the inner side of the limiting ring, so that the plate can be squeezed and fixed on the inner side of the limiting ring, which is convenient for spraying the surface of the plate.

[0014] Furthermore, the paint supply assembly includes a threaded sleeve, which is connected to a threaded sleeve in a limited swinging position at the center of the top of the fixed frame, and the threaded sleeve can swing left and right inside the top of the fixed frame. The threaded sleeve is movably connected to a rotating drum inside, and a turning handle is evenly fixedly installed on the periphery of the top of the rotating drum. A disc is connected to the periphery of the top of the rotating drum in a limited rotation position so that the rotating drum can rotate under the disc, and a feeding pipe is fixedly installed on the top of the disc. The feeding pipe is connected to the rotating drum inside the disc, so that the feeding pipe can pass paint into the rotating drum.

[0015] Furthermore, the rotating drum passes through the threaded sleeve downwardly, and an external thread is provided on the periphery of the middle part of the rotating drum. The external thread and the threaded sleeve engage with each other, and the rotating drum can be driven to rotate by turning the handle. The mutual engagement of the external thread on the periphery of the rotating drum and the threaded sleeve allows the rotating drum to move up and down during rotation.

[0016] Furthermore, a hollow seat is fixedly installed inside the rotating drum, a spring is fixedly connected to the bottom end of the middle part of the hollow seat, a conical plug is fixedly connected to the bottom end of the spring, the connecting tube extends upward to the inside of the rotating drum and is communicated with the rotating drum, the cone head of the conical plug faces downward, and the maximum diameter of the conical plug is smaller than the diameter of the rotating drum and larger than the diameter of the connecting tube, so that when the rotating drum moves upward to be in compression contact with the conical plug, the top opening of the rotating drum can be closed.

[0017] Furthermore, protective rolling doors are slidably provided on the left and right sides of the paint hood, which are closed downward for protection when painting. Conveyor belts are symmetrically fixedly installed on the left and right sides of the paint hood at the top of the body. The conveyor belts cooperate with the left and right movement of the paint hood to facilitate the installation of the plate and the removal after painting.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The present invention, through the design of a rotary paint spraying assembly, while the turntable drives the plate to rotate, utilizes a limit ring to drive the mounting seat and the mounting arch plate to follow the lifting and swinging, so that the nozzle on the mounting arch plate is always vertically facing the plate, and with the movement of the following limit ring, the distance between the nozzle and the plate can also be kept consistent, thereby realizing the vertical and equidistant sweeping spraying of the nozzle toward the plate, ensuring the uniformity of the spraying and improving the effect of the painting.

[0020] 2. The present invention, through the coordinated design of the rotating paint spraying assembly and the paint supply assembly, can intermittently control the paint spraying according to the different widths of the plate. When the nozzle follows the plate to rotate and move to the edge of the plate, the spraying is stopped, thereby avoiding the waste of paint. At the same time, it can also avoid spraying on the narrow side of the plate, so that the installation grooves and connecting holes reserved on the side of the plate will not be blocked, thereby ensuring the normal assembly of the furniture.

[0033] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] A wood furniture processing board painting equipment according to a preferred embodiment of the present invention will be described in detail below. Figure 1-3 As shown, a board painting equipment for processing wooden furniture includes a body 1, a paint hood 2 is slidably connected to the top of the body 1, a turntable 3 is symmetrically rotatably connected to the front and rear sides inside the paint hood 2, a motor 4 is fixedly installed on the front side of the paint hood 2, the motor 4 is transmission-connected to the turntable 3 located on the front side, and then drives the front turntable 3 to rotate, a fixing seat 5 is fixedly installed on the adjacent side of the front and rear turntables 3, a board 6 is fixedly installed between the fixing seats 5, fixing cylinders 7 are symmetrically fixedly installed on the front and rear sides of the top of the paint hood 2, and a fixing frame 8 is fixedly installed between the fixing cylinders 7 on the front and rear sides of the top of the paint hood 2.

[0035] A rotary paint spraying assembly 9 is arranged between the front and rear turntables 3. The rotary paint spraying assembly 9 is used to spray paint evenly and equidistantly on the surface of the plate 6 during the rotation of the plate 6. A paint supply assembly 10 is arranged between the fixed cylinders 7 and above the rotary paint spraying assembly 9. The paint supply assembly 10 is used for accurate intermittent delivery of paint during the painting process.

[0036] Protective rolling doors 11 are slidably mounted on the left and right sides of the paint hood 2. When painting, the protective rolling doors 11 are closed downward for protection. Conveyor belts 12 are symmetrically fixedly mounted on the left and right sides of the paint hood 2 at the top of the body 1. The conveyor belts 12 cooperate with the left and right movement of the paint hood 2 to facilitate the installation of the plate 6 and the removal after painting.

[0037] When spray painting, the plate 6 is placed on the conveyor belt 12 on one side, and then the paint hood 2 is connected to the top of the machine body 1 by means of the limited sliding connection, and the paint hood 2 is moved to the side where the plate 6 is placed, and the plate 6 is squeezed and fixed by coordinating the transmission of the conveyor belt 12 and the action of the fixing seat 5 between the turntables 3 in the paint hood 2, and then the paint hood 2 is moved to the center of the top of the machine body 1.

[0038] After the installation of the plate 6 is completed, the protective rolling door 11 is closed downward, and the front turntable 3 is driven to rotate by the motor 4. The plate 6 is squeezed and fixed between the turntables 3 on both sides, which can drive the plate 6 to rotate between the turntables 3, and cooperate with the rotating paint spraying component 9 and the paint supply component 10 to the left and right to spray paint on the surface of the plate 6.

[0039] After the painting is completed, the protective rolling door 11 is opened upward, and the paint hood 2 is moved to the conveyor belt 12 on the other side, and the plate 6 is released to achieve the removal of the painted plate 6.

[0040] Furthermore, if Figure 3-9 As shown, the front and rear sides of the paint hood 2 are symmetrically connected with turntables 3 for limited rotation, and the front side of the paint hood 2 is fixedly installed with a motor 4, which is transmission-connected to the turntable 3 on the front side, thereby driving the front turntable 3 to rotate.

[0041] The rotary painting assembly 9 includes a limit ring 91, the adjacent bottom ends of the front and rear turntables 3 are fixedly connected to the limit ring 91, a mounting seat 92 is provided on the adjacent side of the front and rear limit rings 91, and a roller 93 is provided on the side away from each other of the front and rear mounting seats 92. The number of rollers 93 at a single mounting seat 92 is four, and they are symmetrically wrapped on both sides of the limit ring 91, so that during the rotation of the limit ring 91, the rollers 93 can be driven to slide on both sides of the limit ring 91, and the top of the front and rear mounting seats 92 is connected to a lifting column on the side away from each other. 94, a mounting arch plate 95 is fixedly installed between adjacent sides of the top of the front and rear mounting seats 92, a paint outlet pipe 96 is fixedly installed on the inner side of the mounting arch plate 95, the outlet of the paint outlet pipe 96 faces downward, and the tops are interconnected, a nozzle 97 is fixedly installed at the outlet of the bottom of the paint outlet pipe 96, and a connecting pipe 98 is rotatably connected to the outer periphery of the top of the paint outlet pipe 96, and the bottom of the connecting pipe 98 is connected to the inside of the paint outlet pipe 96, so that the bottom of the connecting pipe 98 can rotate around the top of the paint outlet pipe 96 while also being able to transport paint to the paint outlet pipe 96.

[0042] A slide groove 921 is provided inside the mounting seat 92, and a connecting block 931 is connected to the slide groove 921 in a limited sliding manner. An elastic curved plate 932 is fixedly connected between the adjacent ends of the left and right connecting blocks 931 and the inner wall of the mounting seat 92. The connecting block 931 is connected to the roller 93 for limited rotation, so that the roller 93 can rotate and move, and through the action of the elastic curved plate 932, when passing through the arcs on both sides of the limiting ring 91, the connecting block 931 can drive the roller 93 to open or contract to pass through the arc edge of the limiting ring 91.

[0043] The top of the lifting column 94 extends upward to the interior of the fixed cylinder 7. A protrusion is provided on the top of the lifting column 94. The protrusion is connected to the inner cavity of the fixed cylinder 7 in a limiting sliding manner. When the limiting ring 91 rotates to a horizontal state with the turntable 3, the protrusion on the top of the lifting column 94 slides to the bottom of the inner cavity of the fixed cylinder 7. Therefore, when the limiting ring 91 starts to rotate from the horizontal state, the lifting column 94 and the mounting seat 92 cannot move downward due to the limitation of the inner cavity of the fixed cylinder 7, thereby driving the lifting column 94 and the mounting seat 92 to move upward.

[0044] The fixing seat 5 is composed of a hydraulic rod and an extrusion seat. The hydraulic rod is fixed at one end adjacent to the front and rear turntables 3. The extrusion seat is fixedly installed at one end adjacent to the hydraulic rod. The hydraulic rod and the extrusion seat are located at the center of the inner side of the limiting ring 91, so that the plate 6 can be squeezed and fixed on the inner side of the limiting ring 91, which is convenient for spraying the surface of the plate 6.

[0045] When the turntable 3 drives the plate 6 to rotate for spraying paint, the turntable 3 can drive the limit ring 91 to rotate synchronously. During the rotation of the limit ring 91, the design of the rollers 93 symmetrically wrapped around the two sides of the limit ring 91 and the design of the top of the mounting seat 92 equipped with the rollers 93 being connected to the lifting column 94 for limited rotation can enable the mounting seat 92 to drive the lifting column 94 to move up and down. Since two symmetrical groups of rollers 93 are provided on each side of the limit ring 91 and the mounting seat 92 can rotate at the bottom of the lifting column 94, the mounting seat 92 always remains horizontal with the side of the limit ring 91, and cooperates with the limited rotation connection between the bottom of the connecting pipe 98 and the paint outlet pipe 96, so that the nozzle 97 on the mounting arch plate 95 fixedly installed between the top of the mounting seat 92 is always vertically facing the plate 6. In the process of the mounting seat 92 following the movement of the limit ring 91, the distance between the nozzle 97 and the plate 6 can also be kept consistent, thereby achieving uniform spraying with the same distance.

[0046] Further, as shown in 4, 9-11, the paint supply assembly 10 includes a threaded sleeve 101, which is connected to the threaded sleeve 101 in a limited swinging manner at the center of the top of the fixed frame 8, and the threaded sleeve 101 can swing left and right inside the top of the fixed frame 8. The threaded sleeve 101 is movably connected to a rotating drum 102 inside. A turning handle 103 is evenly fixedly installed on the periphery of the top of the rotating drum 102, and a disc 104 is connected to the periphery of the top of the rotating drum 102 in a limited rotation manner, so that the rotating drum 102 can rotate under the disc 104, and a feeding pipe 105 is fixedly installed on the top of the disc 104. The feeding pipe 105 is connected to the rotating drum 102 inside the disc 104, so that the feeding pipe 105 can pass paint into the rotating drum 102.

[0047] The rotating drum 102 passes through the threaded sleeve 101 downward, and an external thread 1021 is provided on the outer periphery of the middle part of the rotating drum 102. The external thread 1021 and the threaded sleeve 101 engage with each other, and the rotating drum 102 is driven to rotate by the turning handle 103. The mutual engagement of the external thread 1021 on the outer periphery of the rotating drum 102 and the threaded sleeve 101 allows the rotating drum 102 to move up and down during its rotation.

[0048] A hollow seat 106 is fixedly installed inside the rotating drum 102, and a spring 107 is fixedly connected to the bottom end of the middle part of the hollow seat 106, and a conical plug 108 is fixedly connected to the bottom end of the spring 107. The connecting tube 98 extends upward to the inside of the rotating drum 102 and is connected to the rotating drum 102. The cone head of the conical plug 108 faces downward, and the maximum diameter of the conical plug 108 is smaller than the diameter of the rotating drum 102 and larger than the diameter of the connecting tube 98, so that when the rotating drum 102 moves upward to be squeezed and contacted with the conical plug 108, the top opening of the rotating drum 102 can be closed.

[0049] During the spraying process, the paint enters the drum 102 through the feed pipe 105, passes through the connecting pipe 98 and the paint outlet pipe 96, and finally exits from the nozzle 97 to realize the spraying of the paint.

[0050] In the process of driving the plate 6 to rotate for full spraying, while driving the mounting seat 92 and the mounting arch plate 95 to swing upward, the paint outlet pipe 96 and the connecting pipe 98 are also driven to move upward, and the connecting pipe 98 is connected to the paint outlet pipe 96 by limited rotation, and the rotating drum 102 can follow the swing of the threaded sleeve 101. When the connecting pipe 98 swings upward and contacts with the tapered plug 108 in the rotating drum 102, the bottom end of the connecting pipe 98 can be closed, thereby stopping the paint spraying, and by rotating the rotating drum 102, the outer periphery of the rotating drum 102 is utilized. The mutual engagement of the external thread 1021 and the threaded sleeve 101 can adjust the height of the rotating drum 102, thereby realizing the adjustment of the height of the connecting pipe 98 that is closed by the conical plug 108. It can be adjusted according to the width of the plate 6, so that when the nozzle 97 rotates with the plate 6 and moves to the edge of the plate 6, the spraying is stopped, thereby avoiding the waste of paint. At the same time, it can also avoid spraying the narrow side of the plate 6, so that the installation groove and connecting hole reserved on the side of the plate 6 will not be blocked, thereby ensuring the normal assembly of the furniture.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
