Description

Technical Field

[0001] This utility model relates to the field of iron casting processing technology, and in particular to a painting device for rust prevention treatment of iron castings. Background Technology

[0002] Iron castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and after cooling, it is processed by grinding and other subsequent means to obtain objects with certain shapes, sizes and properties.

[0003] Traditional casting painting equipment can usually only spray one iron casting surface at a time, which is inefficient. After the casting surface is painted, it is difficult for the operator to remove the casting because the paint on the surface is not dry. Direct removal can easily cause the paint to peel off or break, thus affecting the painting effect on the casting surface. Waiting for the paint to cure also greatly increases the painting time. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a painting device for rust prevention treatment of iron castings, thereby solving the problems mentioned in the background art.

[0005] A painting device for rust prevention treatment of iron castings includes a painting station, a drive mechanism for rotating the iron castings, and a painting mechanism for painting the iron castings. The drive mechanism consists of two sets of opposing parts placed on the painting station, including a motor, a connecting rod, a transmission wheel, a transmission wheel, and a support platform. The connecting rod is fixed to the output end of the motor. The transmission wheel consists of two opposing parts fixed on the connecting rod. The transmission wheel is connected to the transmission wheel. The support platform is rotatably mounted on the painting station and fixedly connected to the transmission wheel.

[0006] The painting mechanism includes a toothed plate, a second motor, a gear, a slide block, a slide plate, a fixed plate, a movable seat, a paint spray pipe, and an electric cylinder. The toothed plate is fixedly installed in the middle of the painting station, and the slide plate is fixed to one side of the toothed plate. The second motor slides on the slide plate through the slide block. The gear is fixed at the output end of the second motor and meshes with the toothed plate for transmission. The fixed plate is fixed to the bottom of the slide block. There are two movable seats that slide on both sides of the fixed plate and can be fixed to the fixed plate by pins. The paint spray pipe passes through the movable seat. The electric cylinder is installed on one side of the movable seat, and its output end is fixedly connected to the paint spray pipe through a connecting plate.

[0007] By adopting the above technical solution, two iron castings can be painted simultaneously, thus improving painting efficiency.

[0008] Both the toothed plate and the sliding plate are semi-circular structures, and the distance between their two ends is greater than the distance between the two sets of drive mechanisms.

[0009] By adopting the above technical solution, it is possible to paint the iron castings on the two sets of drive mechanisms separately.

[0010] The spray booth is also equipped with a partition in the middle, which is located on the symmetry line of the two sets of drive mechanisms, as well as the central axis of the toothed plate and the central axis of the slide plate.

[0011] By adopting the above technical solution, the painting of the iron castings on one set of drive mechanisms can be avoided from affecting the other side of the partition.

[0012] The fixed plate has a plurality of connecting holes evenly arranged, and a pin for fixing the movable seat to the fixed plate can pass through the movable seat and be inserted into the connecting hole.

[0013] By adopting the above technical solution, the position of the paint spray pipe is adjusted.

[0014] The top surface of the partition is set to a height no higher than the maximum height that the bottom of the paint spray pipe can rise to.

[0015] By adopting the above technical solution, it is convenient for the paint spraying pipe to pass over the partition.

[0016] The beneficial effects of this utility model of a spray painting device for rust prevention treatment of iron castings are:

[0017] After the spraying is completed, the electric cylinder is controlled to lift the paint spray pipe to the top and drive the second motor to move the paint spray pipe to the other side of the partition to spray the iron castings on the other two support platforms. During the spraying of the other two iron castings, the iron castings that have been sprayed can be selected to use external air drying equipment to speed up the curing of the paint on the iron castings as needed, and then they can be removed, which improves the painting efficiency of the iron castings.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] Reference Figure 1-3 A painting device for rust prevention treatment of iron castings includes a painting station 1, a drive mechanism for rotating iron castings, and a painting mechanism for painting iron castings. The drive mechanism consists of two sets of opposing parts placed on the painting station 1, including a motor 2, a connecting rod 3, a transmission wheel 4, a transmission wheel 5, and a support platform 6. The connecting rod 3 is fixed at the output end of the motor 2. The transmission wheels 4 consist of two opposing parts fixed on the connecting rod 3. The transmission wheel 5 is connected to the transmission wheel 4. The support platform 6 is rotatably mounted on the painting station 1 and is fixedly connected to the transmission wheel 5.

[0024] The painting mechanism includes a toothed plate 7, a second motor 8, a gear 9, a slide 10, a slide plate 11, a fixed plate 12, a movable seat 13, a paint spray pipe 14, and an electric cylinder 15. The toothed plate 7 is fixedly installed in the middle of the painting station 1. The slide plate 11 is fixed to one side of the toothed plate 7. The second motor 8 slides on the slide plate 11 through the slide 10. The gear 9 is fixed at the output end of the second motor 8 and meshes with the toothed plate 7 for transmission. The fixed plate 12 is fixed to the bottom of the slide 10. There are two movable seats 13 that slide on both sides of the fixed plate 12 and can be fixed on the fixed plate 12 by a pin. The paint spray pipe 14 passes through the movable seat 13. The electric cylinder 15 is installed on one side of the movable seat 13, and its output end is fixedly connected to the paint spray pipe 14 through a connecting plate.

[0025] The iron casting can be placed directly on the support platform 6. The drive motor 2 slowly drives the transmission wheel 4 to rotate through the connecting rod 3. The transmission wheel 4 drives the transmission wheel 5 to rotate synchronously. At this time, the support platform 6 can rotate synchronously. The support platform 6 rotates slowly, and the iron casting can be stabilized on the support platform 6 due to its own weight.

[0026] Both the toothed plate 7 and the slide plate 11 are semi-circular structures, with the distance between their two ends greater than the distance between the two sets of drive mechanisms. The side of the slide plate 11 away from the toothed plate 7 is thickened and has an arc-shaped protrusion, which can restrict the slide block 10 to slide stably along the slide plate 11. This can drive the second motor 8 to rotate the gear 9, and the gear 9 can move along the toothed plate 7. At this time, the second motor 8 slides synchronously along the slide plate 11 through the slide block 10, and the slide plate 11 drives the bottom fixed plate 12 to move synchronously. At this time, the paint spray pipe 14 moves to one side of the partition plate 16, and can spray the iron castings on the two support platforms 6 on that side. The external spray pump is started, and the paint liquid is transported to the paint spray pipe 14 through the pipeline and sprayed out from the nozzle at the bottom, thereby spraying the surface of the rotating iron castings. During this period, the electric cylinder 15 can be controlled to drive the paint spray pipe 14 to adjust the distance between the nozzle at the bottom and the iron castings.

[0027] After the spraying is completed, control the electric cylinder 15 to lift the paint spray pipe 14 to the top, and drive the motor 8 to move the paint spray pipe 14 to the other side of the partition 16 to spray the iron castings on the other two support platforms 6.

[0028] During the painting of the other two iron castings, the painted iron castings can be dried using external drying equipment as needed to accelerate the curing of the paint before being removed, thus improving the painting efficiency of the iron castings.

[0029] A partition 16 is also provided in the middle of the spray painting station 1. The partition 16 is set on the symmetry line of the two sets of drive mechanisms, the central axis of the toothed plate 7, and the central axis of the slide plate 11. The partition 16 can separate the spray painting station 1 in the middle, so that the iron castings placed on the two sets of drive mechanisms are separated by the partition 16, which facilitates the subsequent painting process. The top surface of the partition 16 is set to a height that is no higher than the maximum height that the bottom of the paint spray tube 14 can rise. After the two iron castings on one side of the partition 16 are painted, the electric cylinder 15 can be driven to push the paint spray tube 14 upward. When the drive motor 8 moves the fixing plate 12 to the other side of the partition 16, the paint spray tube 14 can pass over the partition 16.

[0030] Multiple connecting holes are evenly arranged on the fixed plate 12. The pin that is used to limit the movable seat 13 on the fixed plate 12 can pass through the movable seat 13 and be inserted into the connecting hole. The position of the paint spray tube 14 can be adjusted according to the actual situation to ensure that different iron casting surfaces can be sprayed.

[0031] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
