[0025] The following is combined with Figure 1-6 This application is described in further detail.

[0026] The present application embodiment discloses a plate painting processing device. Figure 1 The plate painting processing device includes a frame, a conveying mechanism, a loading mechanism, a painting mechanism and a linkage mechanism. The conveying mechanism reciprocates on the frame and supports the loading mechanism, and is used to drive the loading mechanism to reciprocate along the length direction of the frame. The loading mechanism is used to support the plate and drive the plate to move for painting. The painting mechanism is mounted on the frame and is used to realize painting of the plate. The linkage mechanism cooperates with the loading mechanism to drive the part of the loading mechanism supporting the plate to rotate during the movement of the loading mechanism along the length direction of the frame, so that different sides of the plate face the painting mechanism, so as to realize painting of multiple sides of the plate.

[0027] Reference Figure 1 and Figure 2 Specifically, the frame is in the shape of a square frame, and the two ends of the frame that are far away from each other along its own length direction are the feed end 13 and the discharge end 14 respectively. The transmission mechanism includes a conveyor belt 15 that transmits along the length direction of the frame. The conveyor belt 15 is in the form of a conveyor belt. The conveyor belt 15 is driven to move by the cooperation of a roller and a motor. The roller is rotatably connected to the frame, and the motor is installed on the frame and drives the roller to rotate. The conveyor belt 15 can be sleeved on the roller and cooperate with the roller through friction, or it can be achieved by providing a toothed chain in the conveyor belt 15 and a gear on the roller, and the engagement of the conveyor belt 15 with the roller is achieved through the engagement of the toothed chain and the gear. In addition, a roller or a plate that extends along its own length direction and is abutted against the inner surface of the conveyor belt 15 can be provided on the frame to support the conveyor belt 15.

[0028] Reference Figure 1 The paint spraying mechanism includes a main paint spraying group 1 and an auxiliary paint spraying group 2. The main paint spraying group 1 and the auxiliary paint spraying group 2 are distributed along the length direction of the frame, and the main paint spraying group 1 is closer to the feeding section than the auxiliary paint spraying group 2. In the present embodiment, the main paint spraying group and the auxiliary paint spraying group 2 are each provided as one group. In other embodiments, multiple groups of main paint spraying groups 1 and auxiliary paint spraying groups 2 can be provided as needed.

[0029] Reference Figure 1 and Figure 3 , wherein the main spray painting group 1 includes a mounting frame 103, a first spray head 101 and a second spray head 102. The mounting frame 103 is fixedly mounted on the frame in an L-shaped frame, and the first spray head 101 and the second spray head 102 are both distributed on the mounting frame 103. There are multiple first spray heads 101 distributed along the width direction of the frame, and the nozzles of the first spray heads 101 face downwards, which are used to spray paint on the upper surface of the plate; there are two second spray heads 102, which are also distributed along the width direction of the frame, and the nozzles of the two second spray heads 102 face the opposite sides of the frame in the horizontal direction, respectively, which are used to spray paint on the opposite sides of the plate, and all the first spray heads 101 are located between the two second spray heads 102.

[0030] Reference Figure 1 and Figure 4 The auxiliary spray painting group 2 includes an adjustment frame 22 and a third spray head 21. The third spray head 21 has two, and the adjustment frame 22 extends upward from opposite sides of the frame and is respectively connected to the two third spray heads 21, and the nozzles of the two third spray heads 21 are respectively directed toward the opposite sides of the frame in the horizontal direction, so as to spray paint on the opposite sides of the plate.

[0031] Reference Figure 1 and Figure 5 The loading mechanism includes an outer support 3 and an inner support 4. The outer support 3 is connected to the upper surface of the conveyor belt 15. The inner support 4 moves in the outer support 3 and cooperates with the linkage mechanism. The inner support 4 and the outer support 3 support the plate at different times. In the process of the conveyor belt 15 moving the loading mechanism from the feeding end 13 to the discharging end 14, when the plate is sprayed with paint by the main spray painting group 1, the inner support 4 maintains the support for the plate. After passing through the main spray painting group 1 and before reaching the auxiliary spray painting group 2, the inner support 4 is linked by the linkage mechanism, and the inner support 4 moves downward relative to the outer support 3 and rotates 90° at the same time, so that the plate is supported by the outer support 3 after rotating 90°, and then when the plate is sprayed with paint by the auxiliary spray painting group 2, the outer support 3 maintains the support for the plate.

[0032] Reference Figure 5 and Figure 6, wherein the outer support 3 includes a base 31 and a protective basket 32. The base 31 has a square bottom and is fixed on the conveyor belt 15, the base 31 has a hollow cylindrical top and an axis extending vertically, the protective frame is fixed to the top of the base 31, the protective basket 32 ​​has a square basket shape, and has a receiving cavity 7 with an opening facing upward, and the inner cavity of the base 31 passes through the base 31 upward and is connected to the receiving cavity 7.

[0033] The inner support 4 includes a movable column 41 and a support member 42. The movable column 41 is cylindrical with its axis extending vertically. The support member 42 is installed on the top of the movable column 41 and the top surface is a horizontal surface for supporting the plate. The movable column 41 moves coaxially in the inner cavity of the cylindrical section of the base 31. The movable column 41 can rotate along its own axis and move up and down in the inner cavity of the base 31, thereby driving the support member 42 to move in the accommodating cavity 7. The size of the accommodating cavity 7 is larger than the size of the support member 42. The support member 42 can be completely received in the accommodating cavity 7, can also be moved upward out of the accommodating cavity 7, and can also be rotated in the accommodating cavity 7.

[0034] Reference Figure 1 and Figure 6 , the linkage mechanism includes a stay 8 and a guide column 9. The stay 8 extends along the length direction of the frame, and the two ends of the stay 8 that are far away from each other are respectively connected to brackets erected on the two ends of the frame that are far away from each other, and the stay 8 passes through the cylindrical section of the base 31. Among them, the stay 8 includes a first extension section 81, a second extension section 82, a third extension section 83, a fourth extension section 84 and a fifth extension section 85 that are long and connected in sequence along the discharge end 14 of the frame. The first extension section 81, the third extension section 83 and the fifth extension section 85 are parallel to each other and are all parallel to the length direction of the frame in the horizontal direction. The first extension section 81 and the fifth extension section 85 are located on the same horizontal plane, the third extension section 83 is lower than the first extension section 81 and the fifth extension section 85, and the first extension section 81 is located in the range of the main spray painting group 1, and the third extension section 83 is located in the range of the auxiliary spray painting group 2. The second extension section 82 is inclined downward along a direction approaching the third extension section 83 , the fourth extension section 84 is inclined upward along a direction approaching the fifth extension section 85 , and the second extension section 82 and the fourth extension section 84 are mirror-symmetrical along the center line of the third extension section 83 .

[0035] Reference Figure 5 and Figure 6The guide column 9 is cylindrical and fixed to the outer wall of the movable column 41, and the axis of the guide column 9 is perpendicular to the axis of the movable column 41. A guide groove 10 is provided on the cylindrical section of the base 31 for the guide column 9 to press into and slide, and the movement of the guide column 9 in the guide groove 10 drives the inner support 4 to move. Among them, the guide groove 10 has an inclined section 16 and a vertical section 17, and the inclined section 16 extends obliquely along the circumference of the base 31, and the angle at which the inclined section 16 extends along the circumference of the base 31 is 90°; the vertical section 17 is connected to and connected to the bottom end of the inclined section 16 and extends downward at the same time. It should be noted that the bottom of the movable column 41 is always in contact with the upper surface of the support bar 8 due to the gravity of the inner support 4 and the plate, and the movable column 41 is driven to move in the base 31 through the height difference on the support bar 8.

[0036] Reference Figure 1 and Figure 6 When the loading mechanism is located at the feed end 13 of the frame, the support member 42 is in the first state. At this time, the guide column 9 is located at the top of the inclined section 16, and the top of the support member 42 extends out of the top of the enclosure basket 32. The plate is supported by the support member 42, and the loading mechanism drives the plate through the main painting group 1 for painting. During the process, the movable column 41 is always supported by the first extension section 81.

[0037] When the plate is painted by the main painting group 1 and the loading mechanism passes through the second extension section 82, the movable column 41 moves downward due to the height difference of the second extension section 82, so that the guide column 9 moves to the bottom of the vertical section 17, so that the movable column 41 drives the plate to rotate 90° at the same time, and the support member 42 rotates 90° and is stored downward in the enclosure basket 32 ​​at the same time, and the plate abuts against the top of the enclosure basket 32 ​​and is supported by the enclosure basket 32. At this time, the support member 42 is in the second state. When the guide column 9 moves to the junction of the inclined section 16 and the vertical section 17, the top of the support member 42 still exceeds the top of the enclosure basket 32 ​​upward.

[0038] When the loading mechanism passes through the third extension section 83, the support member 42 maintains the second state, and the enclosure basket 32 ​​supports the plate. Similar to the change of the loading mechanism passing through the second extension section 82, when the loading mechanism passes through the fourth extension section 84, the support member 42 returns to the first state to support the plate. When the loading mechanism passes through the fifth extension section 85, the support member 42 maintains the first state. When the support member 42 and the enclosure basket 32 ​​switch to support the plate, the plate will be knocked, thereby removing some bubbles on the paint of the plate.

[0039] Reference Figure 1 , Figure 5 and Figure 6, moreover, the plate painting processing device also includes a material receiving trolley 18, which is placed at the discharging end 14 of the frame. The material receiving trolley 18 is used to receive the plate after painting. The material receiving surface of the material receiving trolley 18 is flush with the top surface of the support member 42 when it is in the first state. The support member 42 includes a support seat 421, a support belt 422, a support roller 423 and a power source 424. The support seat 421 is in the shape of a square basket with an opening facing upward. A plurality of support rollers 423 are arranged along the length direction of the frame and are rotatably connected to the inner cavity of the support seat 421, and the axial direction of the support roller 423 is parallel to the width direction of the frame. The power source 424 is a rotating motor, which is installed on the support seat 421 and is coaxially connected to the support roller 423 at the edge to drive the support roller 423 to rotate. The support belt 422 is in the form of a conveyor belt. The support belt 422 is simultaneously covered with support rollers 423 at both ends of the support seat 421 and supported by the support rollers 423 in the middle. The support rollers 423 rotate to mobilize the conveyor belt to convey in a direction close to the discharge end 14, and the upper surface of the support belt 422 is the top surface of the support member 42, which is used to support the plate. Among them, the power source 424 can be battery-type or plug-in type. When the power source 424 is plug-in type, there is a clearance hole on the enclosure basket 32 ​​to make way for the power cord when the support member 42 is stored in the enclosure basket 32.

[0040] When the loading mechanism drives the plate to move to the discharge end 14, the loading mechanism cooperates with the fifth extension section 85, and the power source 424 is turned on to drive the support belt 422 for transmission. The friction between the support belt 422 and the plate drives the plate to gradually move toward the discharge end 14 and be placed on the receiving trolley 18. The receiving trolley 18 can drive the plate to move to the drying room for direct drying to reduce the contact between the painted plate and personnel.

[0041] Reference Figure 1 and Figure 3Furthermore, in order to enable the main spray paint group 1 to adapt to plates of different sizes, all the first spray heads 101 and the second spray heads 102 are mounted on the mounting frame 103 through the adjusting member 5, and the adjusting member 5 can adjust its position on the mounting frame 103. Specifically, the adjusting member 5 includes an adjusting rod 51, a locking head 52 and a mounting seat 53. The adjusting rod 51 is in the shape of a screw, the locking head 52 is in the shape of a nut and is threadedly sleeved on the adjusting rod 51, and each adjusting rod 51 corresponds to two locking heads 52. The mounting seat 53 is fixed to the bottom end of the adjusting rod 51, and the first spray head 101 and the second spray head 102 are mounted on the corresponding mounting seat 53, and the first spray head 101 and the second spray head 102 are connected to the paint supply tank (not shown in the figure) through a pipeline (not shown in the figure). An adjustment hole 6 is provided at the top of the mounting frame 103 along the width direction of the frame. The adjustment rod 51 can penetrate the adjustment hole 6 vertically and can move along the length direction of the adjustment hole 6. Then, two locking heads 52 are pressed against the upper and lower sides of the top of the mounting frame 103 to achieve the positioning of the adjustment rod 51, so that the adjustment member 5 can adjust the position and quantity of the first nozzle 101 and the second spraying in the horizontal and vertical directions.

[0042] Reference Figure 1 and Figure 4 Furthermore, in order to enable the auxiliary spray painting group 2 to adapt to plates of different sizes, the adjustment frame 22 includes a base frame 221, an extension tube 222 and a mobile frame 223. The base frame 221 is erected on the ground and is composed of a telescopic rod extending vertically. The telescopic rod can be manually telescopic and locked by bolts, or it can be electrically telescopic. The extension tube 222 is fixed to the top of the telescopic rod and extends along the width direction of the frame. The mobile frame 223 has two and one-to-one correspondence with the third spray head 21, and the two mobile frames 223 are respectively located on opposite sides of the frame. The mobile frame 223 is L-shaped, with a cross bar and a vertical bar. The third spray head 21 is installed at the top of the vertical bar of the mobile frame 223. The cross bar of the mobile frame 223 is square rod-shaped and slides in the extension tube 222 along the width direction of the frame. After the position adjustment of the mobile frame 223 is completed, the mobile cross bar is locked to the extension tube 222 by bolts.

[0043] Reference Figure 1 and Figure 2In addition, in order to improve the symmetry of the plate when it is placed on the loading mechanism, the loading mechanism is located in the middle of the conveyor belt 15, and two sets of limit frames 11 are installed at the feeding end 13 of the frame, and the two sets of limit frames 11 are respectively installed on both sides of the frame along its own width direction. Specifically, each set of limit frames 11 includes a base 111, an extension rod 112, a sliding rod 113 and an angle support 114. The base 111 is in an inverted T shape and slides in the frame along the length direction of the frame. The frame is provided with a sliding groove 19 for the base 111 to slide, and the base 111 is threadedly connected with a bolt for pressing against the bottom surface of the sliding groove 19 to position the base 111. The extension rod 112 extends vertically and is fixed to the upper surface of the base 111. The sliding rod 113 extends along the width direction of the frame and slides through the extension rod 112 along the width direction of the frame. The top of the extension rod 112 is threadedly connected with a bolt for pressing against the upper surface of the sliding rod 113 to position the sliding rod 113. The angle seat 114 is fixed to one end of the sliding rod 113 close to the inside of the frame. The angle seat 114 is L-shaped and has a right-angled abutment cavity 12.

[0044] When the plate is placed on the loading mechanism at the feeding end 13 of the frame, the end of the plate close to the feeding end 13 is simultaneously inserted into the abutting cavities 12 of the two corner abutments 114, so that the plate is symmetrical along the central axis of the loading mechanism in both the length and width directions of the frame, so that when the plate passes between the two second nozzles 102 and between the two third nozzles 21, the distances between the two sides of the plate and the corresponding nozzles are consistent, thereby improving the painting effect.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
