Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a printing machine with precise positioning. Background Art

[0002] Corrugated cardboard is made into corrugated cartons through die-cutting, indentation, stapling or gluing. Corrugated cartons are the most widely used packaging products, and their usage has always been the first among various packaging products.

[0003] The Chinese utility model with the authorization announcement number CN219191477U discloses a printing machine for corrugated color boxes that is convenient for precise positioning. When this device is in use, two groups of second telescopic rods are used to clamp and position the corrugated carton from both sides to improve the printing effect. However, when actually using it, when printing on the corrugated carton, pressure is applied to the surface of the carton through the printing roller. Since the corrugated carton has a relatively thin and light corrugated structure, when the printing roller applies pressure, it is easy to cause local indentations or depressions on the surface of the carton. Especially when the clamping force is uneven or too large, this deformation will directly affect the printing quality, making the pattern or text blurred or uneven. Therefore, a printing machine with precise positioning needs to be proposed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and a printing machine with precise positioning is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A printing machine with precise positioning includes a frame. Two groups of driving rollers are rotatably connected inside the frame and are connected to each other through a transmission belt. A side plate is fixedly connected to the side wall of the frame. The outer wall of the side plate is L-shaped. A printing roller is installed below the side plate. A chute is opened on the outer wall of the side plate. Two groups of sliders are slidably connected in the chute. Slide frames are fixedly connected to the outer walls of the two groups of sliders. A double-headed threaded rod two is rotatably connected to the inner wall of the slide frame. Two groups of clamping plates are threadedly connected to the threaded sections of the double-headed threaded rod two. The outer walls of the clamping plates are square.

[0007] Preferably, a limiting rod is fixedly connected to the inner wall of the slide frame. Both groups of clamping plates are slidably connected to the outer wall of the limiting rod.

[0008] Preferably, a double-headed threaded rod one is rotatably connected to the bottom inside the chute. Both groups of sliders are threadedly connected to the threaded sections of the double-headed threaded rod one.

[0009] Preferably, the outer walls of the two groups of sliders are square, and the outer walls on both sides of the two groups of sliders are in close contact with the inner wall of the chute.

[0010] Preferably, a first driving wheel is rotatably connected to the outer walls of both groups of the sliding frames, and the first driving wheel is coaxially and fixedly connected to the adjacent second double-headed threaded rod.

[0011] Preferably, an electric telescopic rod is fixedly connected to the outer wall of the side plate, and a second driving wheel is installed at the telescopic end of the electric telescopic rod.

[0012] Preferably, the second driving wheel is connected to the two first driving wheels by a belt. Preferably, a servo motor is fixedly connected to the outer wall of one of the sliding frames, and its output shaft is coaxially and fixedly connected to the adjacent second double-headed threaded rod.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model clamps and positions the corrugated cardboard box from the four inner corners by four groups of clamping plates. The clamping force acts evenly on the four corners of the cardboard box, avoiding directly applying excessive pressure to the side of the cardboard box, effectively protecting the external structure of the corrugated cardboard box. At the same time, the internal clamping position enables the cardboard box to maintain a stable shape throughout the printing process. Whether during pressure application or transmission, the shape of the cardboard box will not be affected by the clamping force, avoiding the depression problem caused by the traditional method.

[0015] 2. Through the cooperation of the electric telescopic rod, the first driving wheel and the second driving wheel, the whole device operates synchronously during adjustment, ensuring the positioning and transmission stability of the cardboard box, thereby greatly improving the printing accuracy.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer to Figures 1-5 , a printing press with precise positioning, including a frame 1. Two groups of driving rollers are rotatably connected inside the frame 1 and are interconnected by a transmission belt 2. A side plate 3 is fixedly connected to the side wall of the frame 1. The outer wall of the side plate 3 is L-shaped. A printing roller 4 is installed below the side plate 3. A chute 6 is opened on the outer wall of the side plate 3. Two groups of sliders 8 are slidably connected in the chute 6. Slide frames 9 are fixedly connected to the outer walls of the two groups of sliders 8. A double-headed threaded rod two 10 is rotatably connected to the inner wall of the slide frame 9. Two groups of clamping plates 5 are threadedly connected to the threaded sections of the double-headed threaded rod two 10. The outer walls of the clamping plates 5 are square; during specific use, through the sliding of the four groups of clamping plates 5, the four corners of the corrugated cardboard box can be clamped from the inside, and positioning can be carried out from the inside, so as to avoid applying too much pressure to the side of the corrugated cardboard box when clamping from the outside and reduce the risk of deformation of the side of the cardboard box.

[0024] A limiting rod 11 is fixedly connected to the inner wall of the slide frame 9. Both groups of clamping plates 5 are slidably connected to the outer wall of the limiting rod 11. A double-headed threaded rod one 7 is rotatably connected to the bottom of the chute 6. Both groups of sliders 8 are threadedly connected to the threaded sections of the double-headed threaded rod one 7. The outer walls of the two groups of sliders 8 are square. The outer walls of both sides of the two groups of sliders 8 are in close contact with the inner wall of the chute 6; by rotating the double-headed threaded rod one 7, the positions of the two groups of slide frames 9 can be adjusted, so as to improve the flexibility of the device during use.

[0025] Drive wheels one 13 are rotatably connected to the outer walls of the two groups of slide frames 9. The drive wheels one 13 are coaxially fixedly connected to the adjacent double-headed threaded rod two 10. An electric telescopic rod 12 is fixedly connected to the outer wall of the side plate 3. A drive wheel two 14 is installed at the telescopic end of the electric telescopic rod 12. The drive wheel two 14 is connected to the two drive wheels one 13 through a belt 15. The drive wheel two 14 is rotatably connected to the telescopic end of the electric telescopic rod 12. A servo motor is fixedly connected to the outer wall of one of the slide frames 9, and its output shaft is coaxially fixedly connected to the adjacent double-headed threaded rod two 10; by means of the provided drive wheel one 13 and drive wheel two 14, when the positions of the two groups of slide frames 9 are adjusted, in cooperation with the extension and contraction of the telescopic end of the electric telescopic rod 12, it can be ensured that the belt 15 is always tightly attached to the outer wall of the drive wheel one 13.

[0026] In the present invention, when the device is specifically used: the operator rotates the double-headed threaded rod one 7 according to the size and position of the corrugated cardboard box to adjust the positions of the two groups of sliders 8. During this process, the electric telescopic rod 12 starts to work, driving the drive wheel two 14 to slide, so as to ensure the normal operation of the entire transmission system.

[0027] After the carriage 9 is adjusted to the appropriate position, by driving one set of double-headed threaded rods II 10 to rotate with a servo motor, and cooperating with the arranged driving wheel I 13 and driving wheel II 14, the two sets of double-headed threaded rods II 10 can be synchronously driven to continue rotating, driving the clamping plates 5 to slide, and gradually approaching the four corners inside the corrugated cardboard box for clamping, fixing the cardboard box from the inside. This way of internal clamping avoids the problem of side deformation of the cardboard box caused by traditional external clamping, ensuring that the cardboard box maintains a stable shape.

[0028] Subsequently, the printing roller 4 applies uniform pressure to the surface of the corrugated cardboard box for printing. Since the four corners of the cardboard box are stably fixed, the printing roller 4 can accurately complete the printing task without problems such as pattern deviation and ghosting.

[0029] During the entire printing process, the telescopic function of the electric telescopic rod 12 can maintain the close contact between the belt 15 and the driving wheel I 13 by controlling the position change of the driving wheel II 14, ensuring the stable operation of the entire transmission system.

[0030] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
