Description

Technical Field

[0001] The utility model relates to the field of coating devices, in particular to a coating device for processing alloy steel castings. Background Art

[0002] During the processing of alloy steel castings, coating is often required to protect the casting surface from factors such as corrosion, wear, and oxidation. Coating is a common and important process designed to provide protection for the steel plate and improve its surface properties. Typically, this process is achieved by applying a transparent plastic film to the steel plate surface through hot pressing, thus forming a coated steel plate.

[0003] Existing laminating equipment relies on a conveyor mechanism to continuously transport steel sheets, followed by hot-pressing rollers for lamination. However, because the plastic film is supplied in rolls, adjacent castings are often connected when laminating. Accurate film cutting requires pausing the conveyor mechanism before cutting. Frequent pauses result in discontinuous processing, severely impacting lamination efficiency and failing to meet the demands of efficient production.

[0004] After searching, Chinese patent announcement number: CN220681623U discloses a coating device for processing high-strength alloy steel castings, comprising a housing, a conveying mechanism disposed inside the housing; a movable box, the outer surface of the movable box being movably connected to the inner wall of the housing, and notches being provided on the front and back of the housing; and a lifting mechanism, the lifting mechanism comprising a movable plate, a cutting blade being fixedly connected to the bottom of the movable plate, and a round rod being fixedly connected to the front and back of the movable plate. The utility model provides a movable box, a notch, a movable plate, and a round rod. When the movable box moves to the left, the round rod will move to the left within the notch, at which point the round rod will move upward, thereby causing the movable plate and the round rod to move upward as a whole. When the movable box moves to the right, the cutting blade can cut the film, thereby repeating the cutting operation. This eliminates the need for frequent pauses of the coating device, thereby not affecting the efficiency of the coating.

[0005] Although the device has been improved to a certain extent, it still has the following shortcomings. First, because the film is made of flexible material and has a certain toughness, when the device uses a cutting knife to cut the film, the film on both sides of the cutting knife is prone to warping, which in turn affects the quality of the coating. At the same time, the position of the heating roller in the device is fixed and the height cannot be adjusted according to the thickness of the alloy steel casting, and the applicability is poor. Therefore, a coating device for alloy steel casting processing is proposed to solve the above problems. Utility Model Content

[0033] Reference Figure 2 - Figure 4 The cutting assembly includes a fixed plate 61, and a servo motor 63 is provided on the left surface of the fixed plate 61. The servo motor 63 is a prior art and can be realized by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The output shaft of the servo motor 63 can rotate intermittently or continuously. The output shaft of the servo motor 63 is fixedly connected to a positioning plate 62.

The inner wall of the arc groove 601 is slidably connected to the slider 6 4. When the arc groove 601 moves, it squeezes the slider 64 and enables the slider 64 to move back and forth longitudinally. The lower surface of the slider 64 is fixedly connected to the slide rod 65. The lower surface of the slide rod 65 is fixedly connected to the cutting knife 66. The bottom end of the cutting knife 66 is sharp and can cut the film. The slider 64, the slide rod 65 and the cutting knife 66 will move synchronously. The stabilizing component includes a bent rod 51. The outer wall of the bent rod 51 is fixedly connected to a protrusion 54. The upper surface of the protrusion 54 is fixedly connected to one end of a compression spring 53. The bottom end of the rear surface of the bent rod 51 is rotatably connected to a pressure roller 52.

[0034] Reference Figure 1 - Figure 3The adjusting component includes a connecting frame 71, and the inner wall of the connecting frame 71 is provided with a heating roller 72. The heating roller 72 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The upper surface of the connecting frame 71 is fixedly connected to a connecting rod 73, and the connecting frame 71 and the connecting rod 73 will move synchronously. The upper surface of the support frame 1 is provided with a drive motor 74, and the drive motor 74 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The output shaft of the drive motor 74 is fixedly connected to a screw 75, and the drive motor 74 can drive the screw 75 to rotate.

[0035] Reference Figure 2 - Figure 4 The upper surface of the fixed plate 61 is fixedly connected to the lower surface of the support frame 1, the positioning plate 62 is rotatably connected to the inner wall of the fixed plate 61, the sliding rod 65 passes through and is slidably connected to the lower surface of the fixed plate 61, the cutting knife 66 passes through and is slidably connected to the lower surface of the fixed plate 61, the sliding rod 65 and the cutting knife 66 move longitudinally, the bent rod 51 passes through and is slidably connected to the upper surface of the support frame 1, and the other end of the compression spring 53 is fixedly connected to the lower surface of the support frame 1. When the bent rod 51 moves upward, it will drive the protrusion 54 to move upward, squeezing the compression spring 53 to generate a reaction force, and the lower surface of the pressure roller 52 protrudes from the lower surface of the bent rod 51 and can directly contact the film.

[0036] Reference Figure 1 - Figure 3 The connecting rod 73 passes through and is slidably connected to the upper surface of the support frame 1, sliding longitudinally. The screw 75 passes through and is rotatably connected to the upper surface of the support frame 1. The screw 75 passes through and is threadedly connected to the upper surface of the connecting frame 71. When the screw 75 rotates, it will drive the connecting frame 71 to move longitudinally. The lower surface of the heating roller 72 protrudes from the lower surface of the connecting frame 71 and can directly contact the film.

[0037] Working principle: Before using this device, adjust the position of the heating roller 72 according to the thickness of the alloy steel casting. During adjustment, start the drive motor 74 to drive the screw 75 to rotate. The rotating screw 75 will drive the connecting frame 71, the heating roller 72 and the connecting rod 73 to move longitudinally. When the heating roller 72 moves to the appropriate height, turn off the drive motor 74 and then place the alloy steel casting on the support plate 4.

[0038] Then start the heating roller 72 and the conveyor 2 to start the coating work. When the alloy steel casting passes through the heating roller 72, the heating roller 72 will hot-press the film to the surface of the alloy steel casting, and because the film is in a roll and continuous, adjacent castings are connected by the film when coated. At the beginning of the coating work, start the servo motor 63 to drive the positioning plate 62 to rotate. The rotating positioning plate 62 will drive the arc groove 601 to move the extrusion slider 64, thereby enabling the slider 64, the slide rod 65 and the cutting knife 66 to move back and forth longitudinally. The longitudinally reciprocating cutting knife 66 can cut the film, and by adjusting the speed of the output shaft of the servo motor 63, the speed of the positioning plate 62 can be changed, thereby realizing the adjustment of the moving speed of the cutting knife 66 and the adjustment of the film cutting distance.

[0039] During cutting, the pressure rollers 52 on the left and right sides of the cutting blade 66 will adhere to the film due to the elastic push of the compression spring 53, preventing the film from warping when cut, ensuring the flatness of the film and improving the quality of the film.
