Description

Technical Field

[0001] This invention relates to the field of container house production technology, and specifically to a painting device for processing assembled container houses. Background Technology

[0002] Prefabricated container houses, also known as modular container homes or mobile homes, are temporary or permanent buildings that utilize standard shipping containers as basic units and are rapidly assembled through modular design and factory production. Prefabricated container houses generally consist of a detachable frame and side walls that are bolted to the frame. Each part is processed in the factory, painted, dried, and then shipped to the site.

[0003] The dimensions of the side walls of prefabricated container houses are produced according to actual needs, and there will be some differences in size between different batches. Therefore, the painting process is generally done manually. Chinese utility model patent application CN202221833370.X, entitled "A Painting Device for Processing Foldable Container Houses," discloses a relatively automated painting device. However, this device still requires placing the panels on a rack and then spraying paint from the top. Therefore, it cannot paint both sides of the side walls of the prefabricated container house simultaneously, resulting in relatively low efficiency. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a painting device for processing assembled container houses, specifically achieved through the following technical solution: A painting device for processing modular container houses includes a painting booth. Inside the painting booth is a hoisting module for transporting parts to be painted. A second slide rail is installed on the side wall of the painting booth, and a first slide rail is on the ground. A second trolley is installed on the second slide rail, and the second trolley is fixedly installed at one end of a sliding plate. The other end of the sliding plate is fixedly installed on a trolley, which is installed on the first slide rail. A lead screw driven by a second motor is installed on the side of the sliding plate away from the side wall of the painting booth. Third slide rails are installed on both sides of the lead screw. A sliding seat is slidably installed on the third slide rail, and the sliding seat is drivenly connected to the lead screw.

The first rotating shaft passes through the partition and is equipped with a ratchet. A pawl matching the ratchet is installed on the partition.

[0007] The first lifting device is also equipped with a lever assembly for releasing the pawl.

[0008] The actuating assembly includes a third rotating shaft fixedly mounted on a partition plate. The third rotating shaft is hinged to the middle of a pressing plate. The first end of the pressing plate abuts against the second end of a ratchet. The second end of the pressing plate abuts against the first end of a pressure rod. The second end of the pressure rod passes through a limiting block fixedly mounted on the partition plate and is provided with a bent portion. The first end of the pressure rod is threaded with a limiting ring. The second end of the pressure rod is fitted with a second spring, which is located between the bent portion and the limiting block. The tip of the third rotating shaft is fixedly mounted with a first spring seat, on which a first spring piece abuts against the pressing plate is mounted.

[0009] The partition is fixedly connected to the first end of the second rotating shaft, and the second end of the second rotating shaft is rotatably engaged with the middle of the pawl. The first end of the pawl engages with the ratchet, and the second end abuts against the first end of the pressing plate. A second spring seat is fixedly installed on the partition on one side of the pawl. The second spring seat is detachably connected to the first end of the second spring plate, and the second end of the second spring plate abuts against the first end of the pawl. The first trolley includes a first base plate, and a first side plate and a second side plate are fixedly installed on the top two sides of the first base plate, respectively.

[0010] Each of the second wheels is equipped with a first gear, which meshes with a second gear installed at the output end of the first motor.

[0011] The structure of the first vehicle is the same as that of the second vehicle.

[0012] It also includes a second lifting device, which is U-shaped and has a third through hole on its side wall that matches the insertion rod.

[0013] After adopting the above technical solution, the beneficial effects of the present invention are: After the boards are hoisted into the spray booth, the spraying module sprays paint on both sides of the boards in a zigzag pattern. After the painting is completed, the heater is turned on to heat and dry the boards that have entered the spray booth, so that the paint can be cured quickly. The lifting device is small in size, lightweight, easy to operate, and can be used with boards of different sizes.

[0014] The two cranes can move together or independently, making them flexible and convenient for lifting boards of different sizes. Attached Figure Description

[0020] like Figures 1 to 14 As shown, the present invention provides a painting device for processing assembled container houses, including a paint booth 1. A paint spraying device 2 is provided on one side of the paint booth 1. The paint spraying device 2 is used for supplying paint during painting. Its structure is prior art and will not be described in detail. One end of the paint booth 1 is provided with an openable door, and the other end is provided with an exhaust vent 12.

[0021] The interior of the spray booth 1 is equipped with a hoisting module 5 for hoisting the panels waiting to be painted. The hoisting module 5 includes a rail 52 fixedly installed on the top wall of the spray booth 1. Two first trolleys 53 are installed on the rail 52 and can move back and forth along the rail 52. Each first trolley 53 has a crane 54 fixedly installed at its bottom. The two first trolleys 53 are controlled by a controller and can move independently or synchronously.

[0022] A steel wire rope 55 is installed on the crane 54. One end of the steel wire rope 55 is fixedly connected to a lifting device assembly 51. The lifting device assembly 51 is used to be detachably installed on the board. Then, the crane 54 is used to lift the board so that the board is in a vertical position, which is convenient for painting operations.

[0023] The structure of the first trolley 53 is as follows: Figure 10 and Figure 11As shown, it includes a first base plate 5301, on which a first side plate 5302 and a second side plate 5303 are fixedly installed on the top two sides respectively, and a hanging rail 52 is located between the first side plate 5302 and the second side plate 5303.

[0024] Two first wheels 5305 are mounted on the side of the first side plate 5302 facing the second side plate 5303, and two second wheels 5306 are mounted on the side of the second side plate 5303 facing the first side plate 5302, with each second wheel 5306 corresponding to one of the first wheels 5305. A first motor 5304 is fixedly mounted on the side of the second side plate 5303 away from the first side plate 5302. The output end of the first motor 5304 passes through the second side plate 5303 and is located between the two second wheels 5306. Each second wheel 5306 is equipped with a first gear 5307, which meshes with a second gear 5308 mounted on the output end of the first motor 5304.

[0025] The aforementioned crane 54 is fixedly installed at the bottom of the first base plate 5301.

[0026] The structure of the lifting device assembly 51 is as follows: Figures 5 to 9 As shown, the device includes a second lifting device 5101 and a first lifting device 5102. The second lifting device 5101 is U-shaped and has a mounting hole at the bottom. It is detachably mounted on the plate to be painted by bolts. Each of the two side walls of the second lifting device 5101 has a third through hole. The first lifting device 5102 is detachably mounted on the second lifting device 5101, and a lifting ring 5103 is fixedly mounted on the first lifting device 5102. This lifting ring 5103 is fixedly connected to the wire rope 55 of the crane 54.

[0027] The first lifting device 5102 includes an upper cover 5104 and a lower housing 5110 that are bolted together, forming a complete housing. A limiting assembly capable of being inserted into a third through hole and retracting into the lower housing 5110 is installed within the lower housing 5110. The aforementioned lifting ring 5103 is mounted on the first side wall of the lower housing 5110.

[0028] The structure of the limit component is as follows Figures 7 to 9 As shown, the device includes a mounting base 5119 fixedly installed on the second sidewall of the lower housing 5110 corresponding to the upper cover 5104. A slide rail 5124 and a bearing seat 5125 are fixedly mounted on the mounting base 5119. A slider 5122 is mounted on the slide rail 5124. One end of the slider 5122 is fixedly connected to the first end of a push rod 5123. The second end of the push rod 5123 protrudes through the sidewall where the lifting ring 5103 is located, i.e., the first sidewall of the lower housing 5110. A rotatable first rotating shaft 5109 is mounted on the bearing seat 5125. The axis of the first rotating shaft 5109 passes through the geometric center of the lower housing 5110.

[0029] A first hinge plate 5120 and a push plate 5114 are sequentially fixedly mounted on the first rotating shaft 5109. The first end of the first hinge plate 5120 is fixedly mounted on the first rotating shaft 5109, and the middle part of the push plate 5114 is fixedly mounted on the first rotating shaft 5109. The first rotating shaft 5109 passes through the first hinge plate 5120 and the push plate 5114. The first hinge plate 5120 is located between the push plates 5114.

[0030] like Figure 9 As shown, there are two first hinge plates 5120, which are parallel to each other. A hinge shaft is installed between the ends of these two first hinge plates 5120 away from the first rotating shaft 5109. This hinge shaft is hinged to the first end of the second hinge plate 5121, and the second end of the second hinge plate 5121 is hinged to the slider 5122. When the push rod 5123 is pressed, the push rod 5123 pushes the slider 5122 toward the bearing seat 5125, thereby driving the first rotating shaft 5109 to rotate through the second hinge plate 5121 and the first hinge plate 5120. The first rotating shaft 5109 drives the push plate 5114 to rotate.

[0031] Two first guide cylinders 5112 are fixedly installed on the inner sides of the two third sidewalls corresponding to the third through hole of the lower housing 5110. These two first guide cylinders 5112 are arranged along the length of the third sidewall. Each first guide cylinder 5112 is equipped with a guide rod 5117, that is, the first end of the guide rod 5117 is located inside the first guide cylinder 5112 and is provided with a limiting plate. The end of the first guide cylinder 5112 is provided with a limiting ring that matches the limiting plate to prevent the guide rod 5117 from falling out. The end of the guide rod 5117 away from the first guide cylinder 5112 is fixedly installed on the connecting plate 5113. A first spring 5111 is sleeved on the first guide cylinder 5112. One end of the first spring 5111 abuts against the connecting plate 5113, and the other end abuts against the third sidewall of the lower housing 5110.

[0032] A plug rod 5118 is fixedly installed in the middle of the connecting plate 5113. A second guide cylinder 5115 matching the plug rod 5118 is fixedly installed on the third side wall of the lower housing 5110. A second through hole 5116 matching the second guide cylinder 5115 is also provided on the third side wall. The second through hole 5116 matches the third through hole.

[0033] When the push plate 5114 rotates, its two ends abut against the two connecting plates 5113, pushing the connecting plates 5113 to move towards the third side wall of the lower housing 5110, causing the insertion rod 5118 to enter the third through hole. The rotation angle of the push plate 5114 is less than 90 degrees.

[0034] To ensure that the insertion rod 5118 remains within the third through hole during hoisting, a partition 5106 is installed inside the lower housing 5110. The first rotating shaft 5109 passes through this partition 5106 and is fitted with a ratchet 5107. A pawl 5130 matching the ratchet 5107 and an actuating assembly capable of releasing the pawl are also mounted on the partition 5106. To maintain the stability of the first rotating shaft 5109, a bearing is installed where the first rotating shaft 5109 passes through the partition 5106.

[0035] Specifically, the partition 5106 is fixedly connected to the first end of the second rotating shaft 5131, the second end of the second rotating shaft 5131 is rotatably engaged with the middle of the pawl 5130, the first end of the pawl 5130 engages with the ratchet 5107, and the second end abuts against one end of the actuating assembly. A second spring seat 5136 is fixedly installed on the partition 5106 on one side of the pawl 5130, the second spring seat 5136 is detachably connected to the first end of the second spring plate 5132, and the second end of the second spring plate 5132 abuts against the first end of the pawl 5130.

[0036] The first end of the second spring plate 5132 is provided with a first arc-shaped portion 5133, a straight portion 5134, and a second arc-shaped portion 5135 in sequence, wherein the first arc-shaped portion 5133 and the second arc-shaped portion 5135 are centrally symmetrical. The end of the second spring seat 5136 is provided with a straight through groove that matches the straight portion 5134. After the second spring plate 5132 is installed, the straight portion 5134 is located in the straight through groove, and the first arc-shaped portion 5133 and the second arc-shaped portion 5135 abut against the outer wall of the second spring seat 5136.

[0037] A third rotating shaft is also fixedly installed on the partition 5106. The third rotating shaft is hinged to the middle of the L-shaped pressing plate 5128. The first end of the pressing plate 5128 abuts against the second end of the pawl 5130, and the second end of the pressing plate 5128 abuts against the first end of the pressing rod 5137. The second end of the pressing rod 5137 passes through the limiting block 5126 fixedly installed on the partition 5106 and then has a bent portion. The first end of the pressing rod 5137 is threadedly fitted with a limiting ring 5127, which is located between the limiting block 5126 and the pressing plate 5128. The second end of the pressing rod 5137 is fitted with a second spring 5138, which is located between the bent portion and the limiting block 5126.

[0038] A first spring seat 5129 is fixedly installed at the end of the third rotating shaft. The first end of the first spring piece is installed on the first spring seat 5129, and the second end of the first spring piece abuts against the first end of the pressing plate 5128.

[0039] The top cover 5104 is provided with a first through hole 5105 that matches the bent part.

[0040] After the push plate 5114 pushes the insertion rod 5118 into the third through hole, the ratchet 5107, in conjunction with the pawl 5130, fixes the position of the insertion rod 5118. When it is necessary to remove the first lifting device 5102, the bent part is manually turned, the pressure rod 5137 presses the pressure plate 5128, and then the pressure plate 5128 moves the pawl 5130. The pawl 5130 disengages from the ratchet 5107, and under the elastic force of the first spring 5111, the insertion rod 5118 disengages from the third through hole. At the same time, the connecting plate 5113 pushes the push plate 5114 to rotate in the opposite direction and return to its original position; the push plate 5114 drives the first rotating shaft 5109 to rotate, the first rotating shaft 5109 drives the first hinge plate 5120 to rotate, and the first hinge plate 5120 pushes the slider 5122 to move away from the bearing seat 5125 through the second hinge plate 5121.

[0041] The aforementioned actuation component can also be simply replaced by opening a hole in the top cover 5104, allowing the finger to be inserted directly into the hole to actuate the pawl 5130.

[0042] To facilitate a smoother connection between the first lifting device 5102 and the second lifting device 5101, at least one positioning post 5108 is installed on the fourth side wall of the lower housing 5110, away from the lifting ring 5103. The second lifting device 5101 is provided with positioning holes that match the positioning post 5108.

[0043] A painting module 6 for painting both sides of the sheet metal is also installed on the side wall of the spray booth 1. The painting module 6 includes a second slide rail 65 installed on the side wall and a first slide rail 61 installed on the floor of the spray booth 1. A sliding plate 63 is installed between the first slide rail 61 and the second slide rail 65. Specifically, a second trolley 67 with the same structure as the first trolley 53 is fixedly installed on the top of the sliding plate 63. The second trolley 67 is slidably installed on the second slide rail 65.

[0044] A trolley 62 is fixedly installed on the bottom of the skateboard 63. The trolley 62 includes a second base plate 6204 fixedly connected to the skateboard 63. A third side plate 6201 and a fourth side plate 6202 are fixedly installed at both ends of the bottom of the second base plate 6204, and a third wheel 6203 that cooperates with the first slide rail 61 is installed on both the fourth side plate 6202 and the third side plate 6201.

[0045] A lead screw 69, driven by a second motor, is installed on the side of the slide plate 63 away from the side wall of the spray booth 1. Two third slide rails 66 are installed on both sides of the lead screw 69, meaning that two third slide rails 66 are fixedly installed on the slide plate 63, located on opposite sides of the lead screw 69. A nozzle adjustment module 68 is slidably mounted on the third slide rail 66. This nozzle adjustment module 68 is driven by the lead screw 69 and can thus move up and down along the third slide rail 66 via the second motor.

[0046] The nozzle adjustment module 68 includes a slide block 681 that slides in conjunction with the third slide rail 66. The slide block 681 is driven by a lead screw 69. A second hinge seat 686 and a first hinge seat 682 are fixedly mounted sequentially from top to bottom on the side of the slide block 68 away from the slide plate 63. The second hinge seat 686 is hinged to one end of an adjustment seat 684, and the first hinge seat 682 is hinged to the cylinder body of an electric cylinder 683. The output end of the electric cylinder 683 is hinged to the adjustment seat 684. A nozzle 685 is mounted on the adjustment seat 684. The aforementioned painting equipment 2 is connected to the nozzle 685 via a pipeline.

[0047] When the electric cylinder 683 extends, the adjusting seat 684 is in a horizontal position, and the nozzle 685 can spray paint on the board. When the electric cylinder 683 retracts back to its original position, the adjusting seat 684 is in a vertical position, and the nozzle 685 cannot spray paint on the board. This design can prevent the nozzle 685 from affecting personnel movement during maintenance and can also avoid unnecessary damage to the nozzle 685.

[0048] Several sliding rods 64 are also installed on the side and top walls of the spray booth 1 for installing the circuits connecting the various motors and the pipes connecting the spray nozzles 685.

[0049] A heater 13 is installed on the inner wall of the spray booth 1, corresponding to the ventilation window 11, to heat the air entering the spray booth 1. After the painting is completed, the heater 13 is turned on to dry the painted panels.

[0050] A door is installed at one end of the spray booth 1.

[0051] Outside the spray booth 1, a bracket 4 is installed on one side of the door, and an auxiliary rail 3 matching the hanging rail 52 is installed on the bracket 4. At this time, the door is designed with a clearance part matching the auxiliary rail 3.

[0052] In operation, the distance between the two first trolleys 53 is first determined according to the size of the sheet material. Then, the two first trolleys 53 move simultaneously to the auxiliary rail 3. The two first lifting devices 5102 are manually installed on the second lifting device 5101, which is pre-fixed to the sheet material. After lifting the sheet material, it is transported to the designated location in the spray booth 1. The electric cylinder 683 outputs power, and the adjusting seat 684 is in a horizontal position. Then, the second trolley 67 drives the sliding plate 63 to move back and forth, and the second motor drives the adjusting seat 684 to move up and down, forming a zigzag spraying route for simultaneous spraying of both sides of the sheet material. After spraying is complete, the electric cylinder 683 retracts, and the adjusting seat 684 becomes vertical. Then, the heater 13 is activated to dry the sprayed sheet material. After drying, the sheet material is sent to the auxiliary rail 3, unloaded, and replaced with a new sheet material.

[0053] The embodiments described above are not exhaustive and do not limit the invention to specific implementations. Clearly, many modifications and variations can be made based on the above description. These embodiments are selected and specifically described in this specification to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to effectively utilize the invention and its modifications. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
