Double-layer film coating device for metal sealing tank

Abstract

This utility model discloses a double-layer coating device for metal sealing cans, including a base. Support plates are fixedly installed on both sides of the top of the base. A rotating shaft is rotatably connected to both sides of the support plates via bearings. Rollers are fixedly installed on the surface of the rotating shafts. Two rollers are connected by a conveyor belt. This utility model places the metal can to be coated on top of a support rod. After the metal can moves below a second motor, the electric telescopic rod retracts. The retraction of the electric telescopic rod causes a linkage frame to descend, which in turn causes a pressure block to descend. After descending, the pressure block can tightly adhere to the bottom of the can's inner cavity, achieving a clamping effect. At this time, the second motor is activated, causing a rotating rod to rotate. The rotating rod rotates the pressure block, which in turn rotates the can. By connecting a spraying device to a coating nozzle and spraying material through the coating nozzle, a highly efficient coating effect can be achieved.

Description

Technical Field

[0001] This utility model relates to the field of metal sealing can coating, specifically a double-layer coating device for metal sealing cans. Background Technology

[0002] In many industries such as food, chemical, and pharmaceutical, metal sealed containers are widely used for packaging and storing various products due to their good sealing performance, pressure resistance, and corrosion resistance. To further improve the performance of metal sealed containers, such as enhancing sealing performance, achieving rust prevention, light protection, or meeting specific hygiene standards, it is usually necessary to coat the metal sealing caps. Moreover, as the industry's requirements for product quality continue to increase, double-layer coating technology is gradually becoming the mainstream choice.

[0003] Currently, double-layer coating devices for metal sealing caps still have some shortcomings in practical applications. During the coating process, the metal sealing cap needs to be precisely positioned and kept stable to ensure the flatness and adhesion of the coating. However, existing clamping mechanisms are often complex in structure and inconvenient to operate, making it difficult to quickly and stably clamp metal sealing caps of different specifications, thus affecting coating efficiency. At the same time, the double-layer coating process requires the metal sealing cap to rotate along a set trajectory so that the two layers of film can be evenly and orderly covered on the surface of the sealing cap. However, the rotation mechanism of existing devices is mostly not well coordinated with the clamping mechanism, resulting in low rotation accuracy and difficulty in ensuring the alignment and adhesion strength of the two layers of film, which in turn affects the coating quality of the metal sealing cap. Therefore, it is necessary to design a double-layer coating device for metal sealing cans to solve the above problems. Utility Model Content

[0006] The surface of the conveyor belt is rotatably connected to a stop bar through an opening, and several stop bars are arranged in a ring. One end of the stop bar is slidably connected to a ball through a slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This double-layer coating device for metal sealed cans works by placing the metal can to be coated on top of a support rod. After the metal can moves to below the second motor, the electric telescopic rod is retracted. The retraction of the electric telescopic rod causes the linkage frame to descend, which in turn causes the pressure block to descend. After the pressure block descends, it can fit tightly against the bottom of the inner cavity of the can, achieving the effect of clamping the can. At this time, the second motor is started, which drives the rotating rod to rotate. The rotation of the rotating rod drives the pressure block to rotate, which in turn drives the can to rotate.

[0014] 2. This double-layer coating device for metal sealed cans involves placing the metal can to be coated on top of the support rod. After the metal can moves to below the second motor, the electric telescopic rod is controlled to retract. The retraction of the electric telescopic rod causes the linkage frame to descend, which in turn causes the return frame to descend, which in turn causes the calibration plate to descend. After the calibration plate descends, the position of the metal can at the top of the support rod can be calibrated, thereby improving the coating accuracy. Attached Figure Description

A clamping mechanism is provided above the conveyor belt 5. The clamping mechanism includes a linkage frame 12 located above the conveyor belt 5. A second motor 13 is fixedly installed on the top of the linkage frame 12. The output shaft of the second motor 13 is fixedly installed with a rotating rod 14 through a coupling. The bottom end of the rotating rod 14 passes through the linkage frame 12 and extends to the outside of the linkage frame 12. A pressure block 15 is fixedly installed at the bottom end of the rotating rod 14. A film-coating nozzle 16 is fixedly installed at the front and rear of the linkage frame 12 through openings. A sliding groove 10 is provided on the surface of the support plate 2. A slider 11 is slidably connected inside the sliding groove 10. One side of the slider 11 is fixedly connected to the surface of the linkage frame 12. The base 1 An electric telescopic rod 19 is fixedly installed on the rear side of the top. The top of the electric telescopic rod 19 is fixedly connected to the bottom of the linkage frame 12. By setting a clamping mechanism, and by placing the metal can to be coated on the top of the support rod 6, the electric telescopic rod 19 is controlled to retract after the metal can moves below the second motor 13. The retraction of the electric telescopic rod 19 drives the linkage frame 12 to descend. The descent of the linkage frame 12 drives the second motor 13 and the rotating rod 14 to descend. The descent of the rotating rod 14 drives the pressure block 15 to descend. After the pressure block 15 descends, it can be tightly attached to the bottom of the inner cavity of the can, achieving the effect of clamping the can. At this time, by starting the second motor 13, the second motor 13 can drive the rotating rod 14 to rotate. The rotation of the rotating rod 14 drives the pressure block 15 to rotate. The rotation of the pressure block 15 can drive the can to rotate. At this time, by connecting the spraying device with the coating nozzle 16 and spraying material through the coating nozzle 16, the effect of efficient coating can be achieved.

[0024] Specifically, a U-shaped frame 17 is fixedly installed on the top of the linkage frame 12. Calibration plates 18 are fixedly installed on both sides, front and rear of the bottom of the U-shaped frame 17. The bottom of the calibration plate 18 passes through the linkage frame 12 and extends to the outside of the linkage frame 12. By setting the calibration plate 18, and by placing the metal can to be coated on the top of the support rod 6, after the metal can moves below the second motor 13, the electric telescopic rod 19 is controlled to retract. The retraction of the electric telescopic rod 19 causes the linkage frame 12 to descend. The descent of the linkage frame 12 causes the U-shaped frame 17 to descend. The descent of the U-shaped frame 17 causes the calibration plate 18 to descend. After the calibration plate 18 descends, the position of the metal can on the top of the support rod 6 can be calibrated, thereby improving the coating accuracy.

[0025] Working Principle: This utility model is a double-layer coating device for metal sealing cans. The metal can to be coated is placed on top of the support rod 6. After the metal can moves below the second motor 13, the electric telescopic rod 19 retracts. The retraction of the electric telescopic rod 19 causes the linkage frame 12 to descend, which in turn causes the return frame 17 to descend, which in turn causes the calibration plate 18 to descend. After the calibration plate 18 descends, the position of the metal can at the top of the support rod 6 is calibrated. Simultaneously, the descent of the linkage frame 12 causes the second motor 13 and the rotating rod 14 to descend, which in turn causes the pressure block 15 to descend. After the pressure block 15 descends, it fits tightly against the bottom of the can's inner cavity, achieving a clamping effect. At this point, starting the second motor 13 causes the rotating rod 14 to rotate, which in turn causes the pressure block 15 to rotate, which in turn causes the can to rotate. Connecting the spraying device to the coating nozzle 16 and spraying material through the coating nozzle 16 achieves a highly efficient coating effect.
