Description

Technical Field

[0001] The utility model relates to aluminum-plastic packaging equipment, in particular to an automatic deviation-correcting device for printing aluminum-plastic batch numbers. Background Art

[0002] Aluminum-plastic packaging is widely used for various small-particle products, such as capsules and pills. During packaging, batch numbers need to be printed on the aluminum-plastic film. During normal production, as long as the equipment is properly adjusted, the batch number can be accurately printed at the designated location on the aluminum-plastic film. However, during initial startup, the aluminum-plastic film is susceptible to thermal expansion and contraction, which can cause the film to shift. This can cause the batch numbers on the first few printed versions of the aluminum-plastic packaging to shift, resulting in waste of these versions of the drug. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model has the following drawings:

[0012] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0013] As shown in the figure, the automatic deviation correction device for aluminum-plastic batch number printing disclosed in the utility model includes a camera 8 arranged on the traction path of the aluminum-plastic film 3. The camera 8 is used to position and detect the batch number printing bottom frame of the aluminum-plastic film 3. An aluminum-plastic film anti-shake component is provided corresponding to the camera 8. Specifically, the anti-shake component includes a front pressure plate 6 arranged at the feed end and the discharge end of the camera, and a rear pressure plate 9 is provided corresponding to the front pressure plate 6. A spring 7 is provided between the front and rear pressure plates so that the front and rear pressure plates can elastically compress the aluminum-plastic film 3. Through this elastic compression method, the aluminum-plastic film 3 can be pulled and pulled, and the aluminum-plastic film 3 can be ensured not to shake when the traction is suspended, so that the camera 8 can clearly capture the image on the aluminum-plastic film 3 and feedback it to the controller. Furthermore, an elastic wear-resistant layer is provided at the mating ends of the front and rear pressure plates to reduce wear on the aluminum-plastic film. At the discharge end of the camera 8, a batch number printing device 2 and a correction adjustment roller 5 are sequentially provided. The correction adjustment roller 5 is rotatably provided on the moving block 1. The moving block 1 is connected to the mobile drive assembly. The camera 8 can feed back the detection information to the controller, and the controller can control the movement of the mobile drive assembly. In this embodiment, the mobile drive assembly includes a servo motor 4. The output end of the servo motor 4 is connected to a screw rod 11. The screw rod 11 is screwed to the moving block 1. A guide assembly is provided corresponding to the moving block 1. Specifically, the guide assembly includes a guide rod 10 fixed to the frame. The guide rod 10 passes through the upper guide hole of the moving block 1. By controlling the servo motor 4 to drive the screw rod 11 to rotate, the moving block 1 can be driven to move under the guidance of the guide rod 10, thereby adjusting the position of the correction adjustment roller 5.

[0014] The working principle of the present invention is as follows: the aluminum-plastic film 3 is pulled through the camera 8, the batch number printing device 2 and the correcting and adjusting roller 5 in sequence. The camera 8 first captures the image on the aluminum-plastic film 3 and feeds it back to the controller. The controller analyzes the image. If the position of the batch number printing bottom frame on the aluminum-plastic film 3 is correct, the aluminum-plastic film 3 is continued to be pulled by a unit length so that it is sent to the batch number printing device 2 for printing the batch number; if the control analyzes that the position of the batch number printing bottom frame on the aluminum-plastic film 3 is offset, the servo motor 4 is first controlled to drive the mobile drive component to move, drive the moving block 1 and the correcting and adjusting roller 5 to move, and drive the aluminum-plastic film 3 to move until the batch number printing bottom frame moves to the correct position. Then, the aluminum-plastic film 3 is continued to be pulled by a unit length so that it is sent to the batch number printing device 2 for printing the batch number.

[0015] The structure of the present invention can perform visual inspection on the batch number printing bottom frame on the aluminum-plastic film by arranging a camera, and feed back to the control, and then control the mobile driving component through the controller to drive the moving block and the deviation correction adjustment roller to move, so as to correct the deviation of the aluminum-plastic film, thereby ensuring that the batch number printing bottom frame on the aluminum-plastic film is accurately moved to the specified position for batch number printing, and can eliminate the influence of the deviation of the aluminum-plastic film caused by thermal expansion and contraction when the equipment is initially started, thereby ensuring the accuracy of batch number printing and avoiding waste of medicine plates.
