Description

Technical Field

[0001] The present invention relates to the field of furniture processing, in particular to a leakage-proof paint spraying device for furniture production and processing. Background Art

[0002] With the development of industrial technology, modern furniture processing technology has become more and more perfect, and wooden furniture is becoming more and more popular. For the painting operation of octagonal furniture parts, the previous painting equipment will splash paint everywhere, which will easily pollute the painting environment. It is difficult to clean up the paint when it is spilled on the ground or wall.

[0003] Patent No. 202010726934.9 discloses a paint spraying device for furniture production and processing, comprising a machine body, the inner cavity of which is divided into a paint spraying chamber at the upper end and a bottom chamber at the lower end by a horizontally arranged partition, two groups of first electric push rods are symmetrically installed on both sides of the bottom wall of the bottom chamber, and a horizontally arranged lifting plate is connected through the two groups of first electric push rods, a paint liquid tank is installed on the bottom wall of the bottom chamber directly below the lifting plate, and two groups of slide grooves are symmetrically opened on the top of the lifting plate, a group of first lead screws are horizontally passed through the two groups of slide grooves, and the first lead screws in the two groups of slide grooves are both sleeved with slide rods extending into the paint spraying chamber, and the top facing sides of the two groups of slide rods are both provided with plywood. This paint spraying device for furniture production and processing adjusts the flipping of the wooden pole to achieve cyclical painting of the four sides of the wooden pole, without the need for multiple adjustments, and the painting efficiency is higher. At the same time, when adapting to wooden poles of different lengths and sizes, it can also effectively avoid the problem of paint waste;

[0004] This device still has defects when in use. First, the paint spraying device has no protective measures. After the paint is atomized and sprayed, it will splash far away, polluting the factory environment and making it very difficult to clean. Second, the previous paint spraying device has poor linkage and a complex mechanical structure, which makes the device difficult to maintain when damaged. Summary of the Invention

[0005] The purpose of the present invention is to address the deficiencies of the prior art and to provide a leakage-proof paint spraying device for furniture production and processing. When the device is in use, the octagonal furniture component to be processed is placed into the annular groove on the carrying roller. At this time, the electric push rod drives the material transport bridge to slide back and forth along the extended guide rail. When the material transport bridge moves backward, the intermittent clamping assembly locks the furniture component. When the material transport bridge moves forward, the intermittent clamping assembly releases the furniture component. When the paint spraying cross bar starts to spray paint mist, the opening and closing plate starts to twist and wrap into a cylindrical shape, which greatly reduces the paint mist flying out. In addition, the rear end of the opening and closing plate can balance the air pressure during spraying, preventing the formation of vortexes during the painting process.

[0008] Furthermore, a rubber pad is laid on the inner side wall of the annular groove, and the carrying rollers at the front and rear ends have the same height, so that the furniture component remains horizontal in the annular groove.

[0009] Furthermore, the intermittent clamping assembly includes extrusion cylinders on the left and right side walls of the material transport bridge, and the output end of the extrusion cylinder is provided with a clamping piece, and the contour of the clamping piece matches the furniture component.

[0010] Furthermore, the material of the engaging piece is metallic copper, and a mounting hole is provided on the side wall of the engaging piece. A clamping leather pad is provided on the side wall of the engaging piece, and rubber plunger particles matching the mounting hole are provided on the clamping leather pad.

[0011] Furthermore, the outline of the opening and closing plates is trapezoidal, and the opening and closing plates are twisted and wrapped together to form a barrel shape.

[0012] Furthermore, the paint supply assembly includes an annular bag, which is fixedly sleeved on the outside of the traveling tube, and eight towing hoses are led out from the outside of the annular bag. The other end of the towing hose is connected to the paint spraying cross bar, and the annular bag is connected to the paint pump assembly.

[0013] Furthermore, the paint pump assembly includes a paint box and a slurry pump at the top of the load-bearing bridge. A transport pipe is installed at the output end of the slurry pump, and the transport pipe is connected to the annular bag.

[0014] Furthermore, the bottom end of the paint spraying crossbar is provided with spray nozzles arranged in a straight line, and the length of the paint spraying crossbar is smaller than the width of the rear end of the opening and closing plate.

[0016] Beneficial effects of the present invention:

[0017] First, when the device is in use, the octagonal furniture parts to be processed are placed into the annular groove on the carrying roller.

When the material transport bridge moves backward, the intermittent clamping assembly locks the furniture parts. When the material transport bridge moves forward, the intermittent clamping assembly releases the furniture parts. When the paint spraying crossbar starts to spray paint mist, the opening and closing plate begins to twist and wrap into a cylindrical shape, which greatly reduces the paint mist flying out. In addition, the rear end of the opening and closing plate can balance the air pressure during spraying, preventing the formation of vortexes during the painting process.

[0018] Secondly, as the material transport bridge moves backward, the plunger rod penetrates into the fixed plunger cylinder. At this time, hydraulic oil begins to rush into the collecting short tube and the diverging tube. The diverging tube pressurizes each driven plunger cylinder, and then the driven plunger cylinder begins to drive the opening and closing plates to twist and wrap together, achieving a linkage effect.

[0019] Third, the slurry pump extracts the paint from the paint box and presses it into the annular bag through the transport pipe. The annular bag injects paint into the towing hose at the same time. The hydraulic pressure inside the towing hose is the same, so the paint mist sprayed out from each spray bar is more uniform.

The top of the traveling tube 1 is provided with a collecting short tube 5, and the rear end of the collecting short tube 5 is provided with a diverging tube 501. The diverging tube 501 is divided into eight branch tubes, and the branch tubes are respectively connected to the injection cavity inside each driven plunger tube 11. The top of the traveling tube 1 is also provided with a fixed plunger tube 4, and a plunger rod 401 is slidably installed on the inner side of the fixed plunger tube 4. The front end of the plunger rod 401 is connected to the material transport bridge 9. The injection cavity inside the fixed plunger tube 4 is connected to the collecting short tube 5, and the electric push rod 8 drives the material transport bridge 9 to slide back and forth along the extension guide rail 3, and the material transport bridge 9 moves backward. When advancing, the intermittent clamping assembly locks the furniture parts, and when the material transport bridge 9 advances forward, the intermittent clamping assembly releases the furniture parts. While the material transport bridge 9 is advancing, the plunger rod 401 is inserted into the fixed plunger cylinder 4. At this time, hydraulic oil begins to rush into the collecting short tube 5 and the diverging tube 501, and the diverging tube 501 pressurizes each driven plunger cylinder 11, and then the driven plunger cylinder 11 begins to drive the opening and closing plates to twist 7 and wrap them together, realizing the linkage effect, which greatly reduces the paint mist flying out and prevents the formation of vortexes during the painting process.

[0033] like Figure 1 、 2 As shown, the material transfer assembly includes load-bearing plates 201 at both ends of the load-bearing bridge 2, and two carrying shaft seats 202 are provided on the top of the load-bearing plates 201. A carrying roller 203 is provided in the middle of the carrying shaft seat 202 for rotation, and an annular groove matching the contour of the furniture component is provided on the outer side of the carrying roller 203. When the device is in use, the octagonal furniture component to be processed is placed in the annular groove on the carrying roller 203. When the octagonal furniture component is inserted and pushed forward inside the traveling cylinder 1, the carrying roller 203 will rotate accordingly.

[0034] like Figure 1 、 2As shown, a rubber pad is laid on the inner wall of the annular groove, and the carrying rollers 203 at the front and rear ends are of the same height. The furniture component remains horizontal in the annular groove. The rubber pad on the inner wall of the annular groove increases the friction with the furniture component to prevent the annular groove and the furniture from slipping and causing inaccurate positioning of the workpiece.

[0035] like Figure 1 、 3 As shown, the intermittent clamping assembly includes an extrusion cylinder 901 on the left and right side walls of the material transport bridge 9. The output end of the extrusion cylinder 901 is provided with a locking piece 902. The contour of the locking piece 902 matches the furniture component. When the material transport bridge is pushed backward, the extrusion cylinder 901 drives the locking piece 902 to extend out and lock the furniture component. When the material transport bridge is pushed forward, the extrusion cylinder 901 drives the locking piece 902 to retract and release the furniture component.

[0036] like Figure 1 、 3 As shown in Figure 4, the material of the snap-fitting piece 902 is metallic copper, and a mounting hole is provided on the side wall of the snap-fitting piece 902. A clamping leather pad is provided on the side wall of the snap-fitting piece 902, and rubber plunger particles matching the mounting hole are provided on the clamping leather pad. The snap-fitting piece 902 is made of metallic copper and has a certain elasticity. The clamping leather pad on the side wall of the snap-fitting piece 902 will age after a long time. The aged snap-fitting piece 902 can be torn off and replaced with a new one.

[0037] like Figure 1 、 2 As shown in Figure 7, the outline of the opening and closing plate 7 is trapezoidal, and the opening and closing plates 7 are twisted and wrapped together to form a barrel shape, and the material of the opening and closing plate 7 is hard plastic, and a layer of rubber strip is attached to both sides of the opening and closing plate 7. The opening and closing plates 7 with a trapezoidal outline rotate inward at the same time, and then the edges of the opening and closing plates 7 are close together to form a barrel shape, and a chamber is formed inside the opening and closing plates 7 to prevent paint mist from splashing. The box leather strips on the edges of the opening and closing plates 7 increase the airtightness of the device.

[0038] like Figure 1 、 2 As shown in Figure 7, the paint supply assembly includes an annular bag 101, which is fixedly mounted on the outside of the traveling tube 1, and eight towing hoses 703 are led out from the outside of the annular bag 101. The other end of the towing hose 703 is connected to the paint spraying cross bar 701. The annular bag 101 is connected to the paint pump assembly, and the paint pump assembly injects high-pressure paint into the annular bag 101. At the same time, the annular bag 101 injects paint into the towing hose 703. The hydraulic pressure inside the towing hose 703 is the same, so that the paint mist sprayed from each paint spraying cross bar 701 is relatively uniform.

[0039] like Figure 1 、 3As shown, the paint pump assembly includes a paint box 6 and a slurry pump 601 at the top of the load-bearing bridge 2. A transport pipe 602 is installed at the output end of the slurry pump 601. The transport pipe 602 is connected to the annular bag 101. The slurry pump 601 extracts the paint inside the paint box 6 and presses the slurry pump 601 into the annular bag 101 through the transport pipe 602 to facilitate continuous constant pressure feeding.

[0040] like Figure 1 、 7 As shown in Figure 8, the bottom end of the paint spray bar 701 is provided with spray nozzles arranged in a straight line, and the length of the paint spray bar 701 is smaller than the width of the rear end of the opening and closing plate 7. The spray range formed by the paint spray bar 701 forms a dead angle spray on the outside of the furniture parts, and the shorter design of the paint spray bar 701 can prevent the paint spray bars 701 from interfering with each other.

[0041] like Figure 1 、 3 As shown, the diverging tube 501 is made of metallic copper, and the diverging tube 501 is bent into an octagon and is sleeved on the outside of the traveling tube 1. The cross-section of the internal injection chamber of the fixed plunger tube 4 is larger than the cross-section of the internal injection chamber of the driven plunger tube 11. The diverging tube 501 made of metallic copper will not expand when the hydraulic pressure is transmitted, and thus the driven plunger tube 11 will also expand and contract proportionally when the plunger rod 401 does not advance a unit distance.

[0042] Working principle: The electric push rod 8 drives the material transport bridge 9 to slide back and forth along the extension guide rail 3. When the material transport bridge 9 moves backward, the intermittent clamping assembly locks the furniture parts. When the material transport bridge 9 moves forward, the intermittent clamping assembly releases the furniture parts. While the material transport bridge 9 is moving forward, the plunger rod 401 penetrates into the fixed plunger cylinder 4. At this time, hydraulic oil begins to rush into the inside of the collecting short tube 5 and the diverging tube 501. The diverging tube 501 pressurizes each driven plunger cylinder 11, and then the driven plunger cylinder 11 starts to drive the opening and closing plates to twist 7 and pack them together, realizing the effect of linkage, which greatly reduces the paint mist flying out. , which prevents the formation of eddy currents during the painting process. When the device is in use, the octagonal furniture component to be processed is placed in the annular groove on the carrying roller 203. When the octagonal furniture component is inserted and pushed forward inside the traveling cylinder 1, the carrying roller 203 will rotate drivenly. The rubber pad on the inner wall of the annular groove increases the friction with the furniture component, preventing the annular groove and the furniture from slipping and causing inaccurate positioning of the workpiece. When the material transport bridge moves backward, the extrusion cylinder 901 drives the locking piece 902 to extend out and lock the furniture component. When the material transport bridge moves forward, the extrusion cylinder 901 drives the locking piece 902 to retract and release the furniture component. The tool parts, the locking piece 902 is made of metal copper and has a certain elasticity, and the clamping leather pad on the side wall of the locking piece 902 will age after a long time. The aged locking piece 902 will be torn off and replaced with a new one. The trapezoidal outline of the opening and closing plate 7 rotates inward at the same time, and then the edges of the opening and closing plate 7 are close together to form a cylindrical shape. A chamber is formed inside the opening and closing plate 7 to prevent paint mist from splashing. The box leather strips on the edges of the opening and closing plate 7 increase the airtightness of the device. The paint pump assembly injects high-pressure paint into the annular bag 101, and the annular bag 101 injects paint into the towing hose 703 at the same time. The inside of the towing hose 703 The hydraulic pressure is the same, and the paint mist sprayed out by each paint spraying cross bar 701 is relatively uniform. The slurry pump 601 extracts the paint inside the paint box 6, and the slurry pump 601 presses it into the annular bag 101 through the transport pipe 602, so as to facilitate continuous constant pressure feeding. The spray range formed by the paint spraying cross bar 701 forms a dead angle spraying on the outside of the furniture parts, and the paint spraying cross bar 701 is designed to be shorter to prevent the paint spraying cross bars 701 from interfering with each other. The divergent tube 501 made of metal copper will not expand when the hydraulic pressure is delivered, and the driven plunger tube 11 will also expand and contract proportionally if the plunger rod 401 does not advance a unit distance.

[0043] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
