Description

Technical Field

[0001] This utility model relates to the field of curved surface printing technology for elliptical packaging bottles, and more particularly to a curved surface printing device for elliptical packaging bottles. Background Technology

[0002] Oval-shaped bottles are common packaging containers used in the food and cosmetics industries. Curved surface printing is a general term for printing techniques applicable to the surface decoration of three-dimensional curved objects made of materials such as metal, plastic, and glass. The core processes include gravure transfer printing and water pressure transfer printing. Curved surface printing encompasses screen printing, pad printing, letterpress printing, offset printing, inkjet printing, hot stamping, decal printing, and spray printing.

[0003] According to research, existing curved surface printing devices for oval packaging bottles often require adjustments to the flatness of the elliptical shape during placement and clamping, which significantly reduces the operator's placement speed. Furthermore, when performing various printing operations on the elliptical curved surface, the packaging bottle body needs to be rotated, which can easily cause uneven and unclear printing on certain parts of the curved surface due to the influence of the elliptical curved surface.

[0004] Therefore, those skilled in the art have provided a curved surface printing apparatus for elliptical packaging bottles to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a curved surface printing device for elliptical packaging bottles. This device achieves uniform force clamping and positioning of the elliptical packaging bottle through a slidingly arranged positioning clamping block and a limiting arc plate, without the need to adjust its placement position, thus increasing the operator's placement speed. At the same time, the rotating pressure roller shaft reduces the frictional resistance between the roller and the rotating elliptical packaging bottle, improving the flatness of the curved surface printing on the elliptical packaging bottle.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A curved surface printing device for an elliptical packaging bottle includes a support base, a printing roller table, and a pressing support plate. There are two printing roller tables and two pressing support plates. The two printing roller tables are fixedly installed at the front and rear ends of the support base, respectively. The two pressing support plates are fixedly installed on both sides of the support base. A rotating disk is rotatably installed on the upper end of the support base. Multiple positioning clamping blocks are equidistantly slidably installed on the upper end of the rotating disk. Limiting arc plates are slidably installed on the upper ends of both pressing support plates. Multiple pressing roller shafts are equidistantly rotatably installed inside the two limiting arc plates. A rear plate is installed on one side of each of the two limiting arc plates.

[0008] The above technical solution enables uniform force clamping and positioning of oval packaging bottles through the sliding positioning clamping block and limiting arc plate, without the need to adjust the placement position, thus improving the operator's placement speed. At the same time, the rotating pressure roller shaft can reduce the frictional resistance between the roller and the oval packaging bottle in the rotating state, thereby improving the flatness of the curved surface printing of the oval packaging bottle.

[0009] Furthermore, a motor is fixedly installed at the lower end of the support base, and the output end of the motor is fixedly connected to the lower end of the rotating disk;

[0010] By using the above technical solution, the output end of the motor is fixedly connected to the lower end of the rotating disk, which enables the elliptical packaging bottle to be rotated, thereby completing the curved surface printing operation.

[0011] Furthermore, the rotating disk has multiple grooves equidistantly arranged inside, and each of the multiple positioning clamping blocks has a slider fixedly installed at its lower end. The multiple sliders slide inside their respective grooves, and each of the multiple sliders has a fastening spring fixedly connected to one side of its corresponding groove inner wall.

[0012] With the above technical solution, fastening springs are fixedly connected to one side of the slider and to the inner wall of the corresponding groove, which can achieve the clamping and positioning of the oval packaging bottle placed on the rotating disk.

[0013] Furthermore, a telescopic cylinder is fixedly provided between the two corresponding limiting arc plates and the rear plate, and an adjustment spring is sleeved and connected on one side of the two rear plates and on the corresponding telescopic cylinder.

[0014] The above technical solution involves installing adjustment springs on one side of the rear plate and on the corresponding telescopic cylinder to accommodate the switching between the semi-short axis and semi-long axis of the elliptical packaging bottle, ensuring the flatness of the curved surface printing on the elliptical packaging bottle.

[0015] Furthermore, a stabilizing telescopic rod is fixedly installed between the two corresponding limiting arc plates and the rear plate, and at both ends of the telescopic cylinder;

[0016] The above technical solution improves the stability of the limiting arc plate by stabilizing the telescopic rod, further enhancing the uniformity and flatness of printing on various parts of the curved surface of the elliptical packaging bottle.

[0017] Furthermore, an electric telescopic rod is fixedly installed on one side of each of the two rear plates;

[0018] With the above technical solution, an electric telescopic rod is fixedly installed on one side of the rear plate, which can move the limiting arc plate, thereby flattening and further positioning the curved surface printing of the elliptical packaging bottle.

[0019] This utility model has the following beneficial effects:

The device can achieve uniform force clamping and positioning of elliptical packaging bottles through a slidingly arranged positioning clamping block and a limiting arc plate, without the need to adjust the placement position, thereby increasing the operator's placement speed.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Reference Figure 1-5 This utility model provides a specific implementation method:

[0030] A curved surface printing device for an elliptical packaging bottle includes a support base 1, a printing roller table 2, and a clamping support plate 3. There are two printing roller tables 2 and two clamping support plates 3. The two printing roller tables 2 are fixedly installed at the front and rear ends of the support base 1, respectively. The two clamping support plates 3 are fixedly installed on both sides of the support base 1. A rotating disk 4 is rotatably mounted on the upper end of the support base 1. Multiple positioning clamping blocks 6 are equidistantly slidably mounted on the upper end of the rotating disk 4. Limiting arc plates 10 are slidably mounted on the upper end of each of the two clamping support plates 3. Multiple clamping roller shafts 11 are equidistantly rotatably mounted inside each of the two limiting arc plates 10. A rear plate 12 is provided on one side of each of the two limiting arc plates 10. The device is slidably mounted... The positioning clamping block 6 and the limiting arc plate 10 can achieve uniform force clamping and positioning of the elliptical packaging bottle without adjusting its placement position, thus improving the operator's placement speed. At the same time, the rotating pressure roller shaft 11 can reduce the frictional resistance between the roller shaft and the rotating elliptical packaging bottle, improving the flatness of the curved surface printing. A motor 5 is fixedly installed at the lower end of the support base 1, and the output end of the motor 5 is fixedly connected to the lower end of the rotating disk 4. By fixing the output end of the motor 5 to the lower end of the rotating disk 4, the elliptical packaging bottle can be rotated to complete the curved surface printing operation. Multiple sliding grooves 7 are equidistantly opened inside the rotating disk 4, and multiple positioning clamps... Each holding block 6 has a slider 8 fixedly mounted on its lower end. Multiple sliders 8 slide within their respective grooves 7. Each slider 8 has a fastening spring 9 fixedly connected to one side of its corresponding groove 7. These fastening springs 9 allow for clamping and positioning of the elliptical packaging bottle placed on the rotating disk 4. Telescopic cylinders 13 are fixedly mounted between the two limiting arc plates 10 and the rear plate 12. Adjustment springs 14 are sleeved and connected to one side of each rear plate 12 and its corresponding telescopic cylinder 13. These adjustment springs 14 are also sleeved and connected to the rear plate 12 and its corresponding telescopic cylinder 13. 4. To accommodate the switching between the semi-short axis and semi-long axis of the elliptical packaging bottle and ensure the flatness of the printed surface of the elliptical packaging bottle, a stabilizing telescopic rod 15 is fixedly installed between the two limiting arc plates 10 and the rear plate 12, located at both ends of the telescopic cylinder 13. The stabilizing telescopic rod 15 can improve the stability of the limiting arc plate 10 and further enhance the uniformity and flatness of the printing of each part of the elliptical packaging bottle surface. An electric telescopic rod 16 is fixedly installed on one side of each of the two rear plates 12. The electric telescopic rod 16 fixedly installed on one side of the rear plate 12 can move the limiting arc plate 10, thereby flattening and further positioning the printed surface of the elliptical packaging bottle.

[0031] Working principle: When using this curved surface printing device for elliptical packaging bottles, the elliptical packaging bottle is first placed on the rotating disk 4. Then, the electric telescopic rod 16 is activated to move the limiting arc plate 10 to the side of the elliptical packaging bottle (the maximum movement limit of the limiting arc plate 10 is in contact with the semi-short axis of the elliptical packaging bottle). At the same time, the moving motor 5 causes the rotating disk 4 to drive the elliptical packaging bottle to rotate. When the elliptical packaging bottle is continuously rotating, the limiting arc plate 10 is repeatedly moved by the adjustment spring 14 and the telescopic cylinder 13 to adapt to the switching between the semi-short axis and the semi-long axis of the elliptical packaging bottle, thereby realizing the printing operation on the curved surface of the elliptical packaging bottle. The aforementioned sliding positioning clamping block 6 and limiting arc plate 10 can achieve uniform force clamping and positioning of the elliptical packaging bottle without adjusting its placement position, thus improving the operator's placement speed. At the same time, the rotating pressure roller shaft 11 can reduce the frictional resistance between the roller shaft and the rotating elliptical packaging bottle, improving the flatness of the curved surface printing of the elliptical packaging bottle.
