Description

Technical Field

[0001] The present invention relates to the technical field of paint application, and in particular to a mechanized and efficient steel pipe paint application device and method. Background Art

[0002] A lot of steel pipes are used in the construction process. For example, a large number of steel pipes are used in the construction of edge protection, entrance and exit passages, external scaffolds, scissors braces and other structures. In order to improve the warning and marking effects, paint is generally applied to the steel pipes. For example, the commonly seen steel pipes are painted with red and white interval dyes.

[0003] The traditional method for dyeing steel pipes is that workers manually apply the dye with brushes. After dyeing, the steel pipes need to be manually carried and transferred. This method not only has low dyeing efficiency, but also requires workers to be in close contact with the paint and endure the pungent smell of the paint. When carrying out large-scale operations, the labor intensity of workers in carrying steel pipes is high. Based on this, the applicant proposes a mechanized and efficient steel pipe paint application device and method, which can automatically complete the transfer and paint application operations of steel pipes. Summary of the Invention

[0004] To solve the technical problems raised in the background art, the present invention provides a mechanized and efficient steel pipe paint application device and method.

[0005] The present invention is realized by the following technical solutions: A mechanized and efficient steel pipe paint application device and method, including a feeding box, and on one side of the feeding box there is provided:

[0006] A loading tray, the loading tray is rotatably arranged on one side of the feeding box, and a control shaft is arranged on the loading tray, and the control shaft is used to drive the loading tray to rotate;

[0007] A blocking mechanism, the blocking mechanism is arranged in the feeding box, and the blocking mechanism is used to transfer the steel pipes in the feeding box into the loading tray one by one;

[0008] Paint boxes, several paint boxes are arranged on one side of the loading tray, transfer rollers are arranged in the paint boxes, and the distances between several paint boxes are adjustable;

[0009] A driving mechanism, the driving mechanism is arranged above the transfer roller, and the driving mechanism can drive the steel pipe to rotate.

[0010] Through the above technical solution, first, the loading tray can transfer the steel pipes in the feeding box to the position between the driving mechanism and the transfer roller one by one. By controlling the downward movement of the driving mechanism and cooperating with the transfer roller to clamp the steel pipe, and then the driving mechanism drives the steel pipe and the transfer roller to rotate together through friction. When the transfer roller rotates, the paint in the paint box is transferred to the steel pipe to complete painting. At the same time, after painting is completed, by continuously rotating the loading tray, the painted steel pipe can be automatically put down, and a new steel pipe can be placed between the driving mechanism and the transfer roller, repeating the above operations.

[0011] As a further improvement of the above solution, a loading bayonet is provided on the loading tray. At the same time, a spring rod and a support plate are installed in the loading bayonet. The support plate is sleeved on the spring rod, and the support plate can move axially along the spring rod.

[0012] Through the above technical solution, six loading bayonets are provided and are arranged on the loading tray at equal angles. The support plate moves along the spring rod and can approach or move away from the center position of the loading tray.

[0013] As a further improvement of the above solution, the control shaft is fixedly connected to the loading tray, a support seat is rotatably connected to the control shaft, and a motor is connected to one end of the control shaft.

[0014] As a further improvement of the above solution, a carrier is provided below the paint box. An installation groove is provided above the carrier. The paint box is arranged in the installation groove. At the same time, an adjustment hole is provided on the side wall of the installation groove. One side of the paint box is fixedly connected to an adjustment rod. One end of the adjustment rod passes through the adjustment hole, and a fastening knob is threadedly connected to the adjustment rod.

[0015] Through the above technical solution, by rotating the fastening knob, when the fastening knob is in close contact with the outer side wall of the installation groove, the friction force increases and the paint box cannot move, thus fixing the paint box. On the contrary, the paint box can be driven to move in the installation groove through the adjustment rod to adjust the position.

[0016] As a further improvement of the above solution, a connecting frame is also fixedly connected in the paint box, and a transfer roller is rotatably installed on the connecting frame. The transfer rollers are grouped in pairs.

[0017] As a further improvement of the above solution, the driving mechanism includes:

[0018] An electric control telescopic shaft; the lower end of the electric control telescopic shaft is fixedly installed on the top of the feeding box, and the upper end of the electric control telescopic shaft is fixedly connected to an installation platform;

[0019] A driving shaft, the driving shaft is arranged below the installation platform, and driving wheels are fixedly connected to both ends of the driving shaft;

[0020] A pulley, a transfer motor is provided at the top of the installation platform, and the transfer motor and the drive shaft are connected by a pulley.

[0021] As a further improvement of the above solution, the driving mechanism further includes a mounting frame. The upper end of the mounting frame is fixedly connected to the installation platform, and at the same time, the mounting frame is rotatably sleeved outside the drive shaft through a plain bearing.

[0022] Through the above technical solution, first, the electric control telescopic shaft can drive the installation platform and the driving wheel to move downward. When the driving wheel moves downward, it simultaneously pushes the steel pipe downward, so that the upper and lower sides of the steel pipe are respectively in close contact with the driving wheel and the transfer roller. At this time, when the driving wheel rotates, it can drive the steel pipe and the transfer roller to rotate together through friction.

[0023] As a further improvement of the above solution, the blocking mechanism includes:

[0024] A fixed seat, the fixed seat is fixedly connected to the top of the feeding box,

[0025] Blocking rods, there are two blocking rods, including a first blocking rod and a second blocking rod. The fixed seat and the feeding box are provided with blocking holes for the blocking rods to move up and down; a top spring is sleeved outside the second blocking rod;

[0026] A fixed rod, the fixed rod is fixedly connected to the top of the fixed seat, and a balance plate is rotatably connected to the fixed rod;

[0027] An upper connecting rod, the lower end of the upper connecting rod is rotatably connected to the balance plate, and the upper end is rotatably connected to the bottom of the installation platform.

[0028] As a further improvement of the above solution, a first installation hole is provided on the balance plate, a fixing pin is arranged in the first installation hole, a second installation hole is provided at the upper end of the blocking rod, the upper end of the blocking rod is inserted into the first installation hole, and at the same time, the fixing pin penetrates through the second installation hole.

[0029] Through the above technical solution, initially under the turntable, the top spring pushes the second blocking rod upward. At this time, the balance plate is in a horizontal state, and the lower end of the first blocking rod is inside the feeding box, blocking the steel pipe. When the upper connecting rod moves downward, it pushes the second blocking rod downward and into the feeding box. At this time, the first blocking rod moves upward under the drive of the balance plate and out of the feeding box. Therefore, the steel pipe located between the first blocking rod and the second blocking rod automatically falls. That is, only one of the first blocking rod and the second blocking rod is inside the feeding box at the same time.

[0030] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0031] 1. When the installation platform moves downward in the present invention, it drives the steel pipe to move downward along the feeding bayonet, and drives the steel pipe and the transfer roller to rotate together through friction. The transfer roller automatically transfers the paint onto the steel pipe. At the same time, the feeding bayonet can prevent the steel pipe from shifting in position during the movement or rotation, ensuring the smooth completion of the painting process.

[0032] 2. When the installation platform moves up and down in the present invention, the first blocking rod and the second blocking rod can move down or enter the inside of the feeding box, so that the steel pipes in the feeding box can be transferred one by one into the feeding bayonet of the feeding tray. Cooperating with the feeding tray to drive the steel pipe to rotate, it can automatically complete the feeding, transfer printing and painting, and the final blanking processes, improving work efficiency.

Detailed implementation

[0043] Next, in combination with the accompanying drawings and specific implementation manners, the present invention will be further described. It should be noted that, on the premise of no conflict, the following described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0044] Embodiment 1:

[0045] Please refer to Figures 1-6 , a mechanized and efficient steel pipe painting device and method in this embodiment includes a feed box 1. In actual use, the feed box 1 can be arranged on one side of a conveyor. The conveyor transports the steel pipe into the interior of the feed box 1. One end of the feed box 1 is inclined so that the steel pipe can fall along the inclined surface. In addition, a support member (not marked in the figure) is arranged below the feed box 1.

[0046] Therefore, one end of the feed box 1 is inclined and is the outlet end. A paint box 4 for placing paint is arranged on the outlet side. Therefore, in actual use, it is necessary to paint the steel pipes at intervals with different colors (such as red and white intervals). Therefore, in this embodiment, three paint boxes 4 are provided. A connecting frame 5 is fixedly installed in the paint box 4, and a transfer roller 6 is rotatably installed on the connecting frame 5, and two transfer rollers 6 are arranged side by side in each paint box 4. Paint is placed in the paint box 4, and the lowest point of the transfer roller 6 is below the liquid level, that is, it can contact the paint.

[0047] To install the paint box 4, a carrier frame 7 is arranged below the paint box 4. An installation groove 71 is opened at the upper end of the carrier frame 7, and the paint box 4 is located in the installation groove 71. A support structure (not marked in the figure) is arranged below the carrier frame 7.

[0048] In actual use, according to different usage requirements and the lengths of steel pipes, the painting positions on the steel pipes are different. Therefore, it is necessary to adjust the position of the transfer roller 6 (paint box 4). Therefore, a long strip-shaped adjustment hole 72 is provided on the side wall of the installation groove 71, and an adjustment rod 41 is fixedly connected to the side of the paint box 4. One end of the adjustment rod 41 penetrates through the adjustment hole 72. Therefore, the paint box 4 can be driven to move in the installation groove 71 by the adjustment rod 41. In order to fix the paint box 4, a fastening knob 42 is also required. The fastening knob 42 is threadedly connected to the adjustment rod 41. Rotate the fastening knob 42 so that one end fits against the carrier 7. The adjustment rod 41 is fixed by increasing the friction force so that it cannot move. Therefore, the paint box 4 is also fixed.

[0049] In order to make the steel pipes in the feeding box 1 fall onto the transfer roller 6 for painting. Therefore, a loading tray 2 is provided, and the loading tray 2 is used to transfer the steel pipes.

[0050] Specifically, six "U"-shaped loading notches 21 are provided on the loading tray 2 at equal angles along the circumferential direction. In addition, a support plate 23 is provided in the loading notch 21. The middle of the support plate 23 is arc-shaped, which is convenient for contacting the steel pipe. In addition, spring rods 22 are provided on both sides of the support plate 23. The spring rods 22 are fixedly connected in the loading notch 21, and at the same time, the spring rods 22 penetrate through the support plate 23. That is, the support plate 23 can move along the spring rods 22.

[0051] In this embodiment, two loading trays 2 are provided. According to actual needs, if the steel pipe is too long, the number of loading trays 2 can be increased. A control shaft 3 is provided between the two loading trays 2 in this embodiment, and the control shaft 3 is fixedly connected to the two loading trays 2.

[0052] A support seat 31 is rotatably installed on the outside of the control shaft 3. At the same time, in order to drive the control shaft 3 to rotate, one end of it is connected to a motor, and the motor is fixedly installed on the support seat 31.

[0053] In this embodiment, the control shaft 3 penetrates through the above-mentioned carrier 7 as a whole and is rotatably connected to the carrier 7 through a plain bearing. As described above, three paint boxes 4 are provided in this embodiment, and two loading trays 2 are provided. During use, the loading trays 2 and the paint boxes 4 are arranged at intervals.

[0054] When the steel pipe moves along the inclined feeding box 1, when the loading notch 21 corresponds to the outlet position, that is, the steel pipe enters the loading notch 21. Then, the motor drives the control shaft 3 and the loading tray 2 to rotate. When the loading notch 21 carrying the steel pipe is in the vertical direction, at this time, the steel pipe is directly above the transfer roller 6 and is not in contact with the transfer roller 6. In order to make the steel pipe fit with the transfer roller 6 and transfer the paint in the transfer roller 6 and the paint box 4 to the steel pipe, a driving wheel 84 is provided above the transfer roller 6. At this time, the steel pipe is located between the driving wheel 84 and the transfer roller 6.

[0055] In addition, an electrically controlled telescopic shaft 81 is fixedly installed on the top of the feed box 1, and a mounting platform 82 is fixedly connected to the upper end of the electrically controlled telescopic shaft 81. A transfer motor (not marked in the figure) is installed on the mounting platform 82, and a drive shaft 83 is arranged below the mounting platform 82. The transfer motor and the drive shaft 83 are connected by a pulley 85. The drive wheel 84 is fixedly connected to the drive shaft 83. That is, a drive wheel 84 is fixedly installed at each end of the drive shaft 83.

[0056] In addition, a mounting frame 86 is sleeved on the outer side of the driving shaft 83 . The driving shaft 83 and the mounting frame 86 are rotatably connected via a plane bearing, and the upper end of the mounting frame 86 is fixedly connected to the mounting platform 82 .

[0057] Therefore, when the above-mentioned electric control telescopic shaft 81 controls the mounting platform 82 to move downward as a whole, the driving wheel 84 also moves downward. After the driving wheel 84 contacts the steel pipe, it will push the steel pipe to move downward, and the steel pipe will push the support plate 23 to move in the feeding clamp 21, compressing the spring on the spring rod 22. Until the steel pipe contacts the transfer roller 6 below. In actual use, there will be a sponge layer on the surface of the transfer roller 6 that absorbs paint, so there is no need to worry about the steel pipe crushing the transfer roller 6.

[0058] When the driving wheel 84 continues to move downward, the driving wheel 84, the steel pipe and the transfer roller 6 are finally closely fitted. Since the steel pipe is always in the loading bayonet 21 during the movement process, there is no need to worry about the lateral displacement of the steel pipe.

[0059] At this time, the transfer motor drives the drive shaft 83 and the drive wheel 84 to rotate together through the pulley 85. The drive wheel 84, the steel pipe and the transfer roller 6 are tightly fitted, that is, when the drive wheel 84 rotates, the steel pipe and the transfer roller 6 can be driven to rotate by friction. The steel pipe rotates in the feeding clamp 21, and the transfer roller 6 rotates on the connecting frame 5. When the transfer roller 6 rotates, the paint in the paint box 4 is transferred to the steel pipe. The steel pipe is painted.

[0060] Embodiment 2:

[0061] Combination Figures 7-9 Based on Example 1, this embodiment is further improved in that:

[0062] As described above, in order to facilitate automatic loading, one end of the feed box 1 is set to an inclined state. Since the steel pipes in the inclined section will continue to move downward, in order to coordinate with the rotation of the loading tray 2 and load the materials in an orderly manner, a blocking mechanism 9 is set at the outlet of the feed box 1. The blocking mechanism 9 can transfer the steel pipes in the feed box 1 to the loading bayonet 21 of the loading tray 2 in an orderly manner.

[0063] Specifically, the blocking mechanism 9 includes a fixed seat 91. First, the fixed seat 91 is fixedly connected to the top of the feeding box 1, and blocking holes 93 are provided at corresponding positions on the fixed seat 91 and the top of the feeding box 1. A blocking rod 92 is arranged in the blocking hole 93.

[0064] In this embodiment, two blocking rods 92 are provided. Referring to Figure 8 , the one on the right is defined as the first blocking rod 921 (close to the loading tray 2), and the one on the left is the second blocking rod 922 (far from the loading tray 2).

[0065] At the same time, a fixed rod 10 is fixedly connected to the fixed seat 91, and a balance plate 11 is rotatably connected to the top of the fixed rod 10, that is, the balance plate 11 can rotate around its connection point with the fixed rod 10.

[0066] In order to enable the balance plate 11 to drive the first blocking rod 921 and the second blocking rod 922 to move up and down, a first mounting hole 12 is provided in the balance plate 11, and a fixed pin 14 is fixedly arranged in the first mounting hole 12. At the same time, second mounting holes 13 are provided at the upper ends of the first blocking rod 921 and the second blocking rod 922. The upper ends of the first and second blocking rods 922 are inserted into the first mounting hole 12, and the fixed pin 14 passes through the second mounting hole 13. In addition, a jacking spring 94 is sleeved outside the second blocking rod 922.

[0067] In the initial state, the balance plate 11 is in a horizontal state. Under the action of the jacking spring 94, the second blocking rod 922 moves upward. The length of the second blocking rod 922 is shorter. At this time, the upper ends of the two blocking rods 92 are flush. The lower end of the second blocking rod 922 is located outside the feeding box 1, and the lower end of the first blocking rod 921 is located inside the feeding box 1.

[0068] In order to facilitate the control of the two blocking rods 92 to move up and down along the blocking holes 93, an upper connecting rod 15 is also provided. The upper end of the upper connecting rod 15 is rotatably connected to the mounting platform 82, and the lower end is rotatably connected to the balance plate 11.

[0069] Therefore, in summary, when the above-mentioned mounting platform 82 moves downward, it pushes the upper connecting rod 15 downward. Referring to Figure 8 the state shown, when the upper connecting rod 15 moves downward. It pushes the balance plate 11 to rotate counterclockwise around its connection point with the fixed rod 10, pushes the second blocking rod 922 to move downward, and at the same time drives the first blocking rod 921 to move upward.

[0070] Since the second mounting holes 13 are provided in the first blocking rod 921 and the second blocking rod 922, the first blocking rod 921 and the second blocking rod 922 can move within the above-mentioned first mounting holes 12. With the limiting effect of the blocking holes 93 on the blocking rod 92, even when the balance plate 11 rotates counterclockwise, only the first blocking rod 921 and the second blocking rod 922 can be driven to move up and down by the positioning pin, and they will not rotate.

[0071] As Figure 8 shown, if the first blocking rod 921 moves upward and out of the feeding box 1 at this time, the steel pipe at the rightmost end in the figure will automatically fall along the inclined plane; at the same time, the second blocking rod 922 moves downward into the interior of the feeding box 1 to intercept the steel pipe in the middle. At this time, only one steel pipe falls along the inclined plane and enters the feeding tray 2.

[0072] Conversely, when the installation platform 82 rises and resets, the balance plate 11 returns to the horizontal position. At this time, the steel pipe continues to move along the inclined plane and finally becomes Figure 8 the state shown. That is, only one of the first blocking rod 921 and the second blocking rod 922 is located inside the feeding box 1 at the same time. The first and second blocking rods 922 alternately enter and exit the feeding box 1, so that the steel pipes can fall into the feeding tray 2 one by one in an orderly manner.

[0073] The implementation principle of a mechanized and efficient steel pipe painting device and method in this application is as follows:

[0074] (1): This device can be connected to a conveyor device, that is, the steel pipes are conveyed into the feeding box 1 through the conveyor device. Since one end of the feeding box 1 is inclined, the steel pipes will accumulate at the inclined plane and be blocked by the first blocking rod 921. In the initial state, the first blocking rod 921 is located inside the feeding box 1, and the second blocking rod 922 is located outside the feeding box 1.

[0075] At the same time, according to actual needs, the position of the paint box 4 is adjusted by moving the adjusting rod 41, that is, the position of steel pipe painting is adjusted, and then the fixing knob 42 is tightened to fix the paint box 4.

[0076] (2): Control the hydraulic lifting rod to contract and extend, driving the installation platform 82 to move downward first and then upward to reset. During this process, the installation platform 82 first pushes the balance plate 11 to rotate counterclockwise around the connection point between itself and the fixed rod 10 through the upper connecting rod 15, driving the lower end of the first blocking rod 921 to move out of the feeding box 1 and the lower end of the second blocking rod 922 to enter the feeding box 1. At this time, one steel pipe is released and falls along the inclined plane into the feeding bayonet 21 of the feeding tray 2. Then when the installation platform 82 moves upward and resets, the first and second blocking rods 922 and the steel pipes in the feeding box 1 return to Figure 8 the state shown.

[0077] (3): Refer to Figure 2, if the steel pipe enters the feeding bayonet 21, the control shaft 3 and the feeding tray 2 are driven by the motor. When the feeding tray 2 rotates (clockwise) by 60 degrees. At this time, the steel pipe is located between the driving wheel 84 and the transfer roller 6.

[0078] (4): Control the installation platform 82 to move downward, and the driving wheel 84 moves downward at the same time, pressing down on the steel pipe. The steel pipe and the pallet 23 move downward. At this time, the steel pipe and the pallet 23 move within the feeding bayonet 21. Until the lower end face of the steel pipe contacts the transfer roller 6. That is, the upper and lower parts of the steel pipe are in close contact with the driving wheel 84 and the transfer roller 6 respectively. At this time, the driving shaft 83 is driven by rotating the motor and the pulley 85. The driving wheel 84 rotates. The driving wheel 84 drives the steel pipe and the transfer roller 6 to rotate together through friction.

[0079] The movement and rotation of the steel pipe are within the feeding bayonet 21, so there is no need to worry about the steel pipe shifting. And the transfer roller 6 can contact the paint in the paint box 4. When it rotates, it will transfer the paint in the paint box 4 to the steel pipe. Coupled with the rotation of the steel pipe itself, the surface of the steel pipe can be evenly painted.

[0080] (5): After the steel pipe is painted, control the installation platform 82 to reset. At the same time, control the feeding tray 2 to continue rotating. At this time, an unpainted steel pipe will enter the middle position between the driving wheel 84 and the transfer roller 6, and the already painted steel pipe will automatically fall from the side of the feeding tray 2 away from the feeding box 1. Automatic blanking is completed.

[0081] Therefore, by driving the entire installation platform 82 to move downward through the electric control telescopic shaft 81, while painting the steel pipe, it can also cooperate with the blocking mechanism 9 to make the steel pipes in the feeding box 1 enter the feeding tray 2 orderly and one by one. Then, in cooperation with the rotation of the feeding tray 2, the feeding and falling processes are completed.

[0082] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
