Description

Technical Field

[0001] This utility model relates to a paper tube marking and covering device, belonging to the technical field of paper tube marking and covering equipment. Background Technology

[0002] Traditional paper tube marking and covering methods mainly rely on manual operation, including manually applying covering agents (such as special covering inks and coatings), manually pasting covering labels, and manually sanding the marked areas. These methods have obvious technical shortcomings: First, they are inefficient. Manual operation requires processing each paper tube individually, and marking and covering each paper tube typically takes 10-30 seconds, which is difficult to adapt to the processing needs of modern production lines that handle dozens or even hundreds of paper tubes per minute, easily creating a bottleneck in the production line. Second, the covering quality is unstable. Manual application is prone to missed areas and uneven thickness, causing the original markings to show through, while manual sanding may damage the paper tube surface due to improper force control, affecting subsequent use. Third, the working environment is poor and the cost is high. Harmful substances volatilized from the covering agent during manual application can endanger the health of operators, and labor costs continue to rise with the increase in enterprise labor demand. At the same time, the high error rate of manual operation also leads to an increase in the scrap rate of paper tubes, further increasing production costs. Against this backdrop, developing a paper tube marking and covering device that can achieve automated operation, adapt to various paper tube specifications and marking types, ensure stable covering quality, and reduce operating costs has become a key technological direction for solving the pain points in the current paper tube processing process. It has important practical significance and industrial value for improving enterprise production efficiency, reducing operating costs, and improving the working environment. Utility Model Content

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0018] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0019] like Figures 1-9As shown, a paper tube marking and covering device is disclosed, including a conveying mechanism 4 disposed on a lower frame 2, an upper frame 1 disposed on the lower frame 2, a front inkjet mechanism 6 disposed on one side of the conveying mechanism 4 and a rear inkjet mechanism 5 disposed on the other side of the lower frame 2, for reference. Figure 2 As shown, the paper tube 3 is placed on the transport fixture, the transport mechanism 4 moves between the front inkjet mechanism 6 and the rear inkjet mechanism 5, and then rises to the height of the inkjet gun 14. The front inkjet mechanism 6 and the rear inkjet mechanism 5 move towards both ends of the paper tube 3, so that the inkjet gun 14 moves to both ends of the paper tube to cover and mark.

[0020] In the specific implementation process, such as Figure 3 As shown, the conveying mechanism 4 includes a conveying motor 7, a linear guide rail 12, and a lifting device; The output end of the conveying motor 7 is connected to a conveying lead screw 8, and a threaded block 9 is provided on the conveying lead screw 8. A support plate 13 is slidably provided on the linear guide rail 12. The support plate 13 is connected to the threaded block 9. The lifting device is connected to the bottom of the support plate 13 and a conveying fixture for placing the paper tube 3 is connected through the support plate 13. The specific process is as follows: First, the conveying motor 7 is a servo motor. The rotation of the conveying motor 7 drives the conveying lead screw 8 to rotate, thereby causing the threaded block 9 to move on the conveying lead screw 8, which in turn drives the support plate 13 to move along the linear guide rail 12. Since the lifting device is connected to the support plate 13, the conveying fixture 26 and the lifting device are moved between the front inkjet mechanism 6 and the rear inkjet mechanism 5. At this time, the lifting device is raised, raising the paper tube on the conveying fixture 26 to the height of the inkjet gun 14.

[0021] In the specific implementation process, such as Figure 3 As shown, the lifting device includes a lifting motor 10 and a linear module 11. The lifting motor 10 is connected to the linear module 11. The linear module 11 passes through the support plate 13 and is connected to the conveying fixture 26. It should be noted that the linear module 11 and the support plate 13 are slidably connected. The lifting motor 10 drives the linear module 11 to rise, which in turn drives the conveying fixture 26 to rise.

[0022] like Figures 4-5 As shown, the front inkjet mechanism 6 includes a front linear motion mechanism, which is connected to a fixed plate 19. The fixed plate 19 is provided with multiple inkjet guns 14. A front roller group 15 is provided on the fixed plate 19 below the inkjet guns 14. The front roller groups 15 are in pairs and work with the pressure roller 22 to place the paper tube 3. The paper tube 3 is rotated by the rotation of the active roller in the pressure roller 22, thereby covering the markings on the paper tube 3.

[0023] In this embodiment, the front linear motion mechanism includes a front servo motor 17, a front linear guide rail 16, and a ball screw 18. The output end of the front servo motor 17 is connected to the ball screw 18. The ball screw 18 is provided with a threaded block. The threaded block is connected to the bottom of the fixed plate 19. The bottom sides of the fixed plate 19 are slidably connected to the front linear guide rail 16. The front servo motor 17 rotates, driving the ball screw 18 to rotate, causing the threaded block to move on the ball screw 18, thereby driving the fixed plate 19 to move along the front linear guide 16, and then moving the inkjet gun 14 to one end of the paper tube 3. The rear inkjet mechanism 5 moves the inkjet gun 14 on the rear inkjet mechanism 5 to the other end of the paper tube 3.

[0024] like Figure 6 and Figure 7 As shown, in this embodiment, the rear inkjet mechanism 5 includes a rear linear motion mechanism. A fixed plate 19 is provided on the rear linear motion mechanism, and multiple inkjet guns 14 are provided on the fixed plate 19. A lower pressure roller 22 is provided below each inkjet gun 14 on the fixed plate 19, and a lifting cylinder 20 is provided above each lower pressure roller 22. An upper pressure roller 21 is provided at the output end of the lifting cylinder 20. The rear linear motion mechanism includes a linear cylinder 23 and a rear linear guide rail. The rear linear guide rail is connected to the fixed plate 19, and the actuating end of the linear cylinder 23 is connected to the fixed plate 19. Specifically, in this embodiment, the linear cylinder 23 extends, pushing the fixed plate 19 to move along the linear guide rail, thus moving the inkjet guns 14 on the rear inkjet mechanism 5 to the other end of the paper tube 3.

[0025] like Figure 8 As shown, the lower pressure roller 22 is driven by a roller motor 24. The lower pressure roller 22 has multiple sets, each set including a driving roller and a driven roller. The driving and driven rollers are connected by a belt. The roller motor 24 is connected to the driving roller via a belt 25. The roller motor 24, through a synchronous belt, drives the driving roller to rotate, which in turn drives the paper tube to rotate. The upper pressure roller 21 descends via a lifting cylinder 20, pressing down on the paper tube 3 as it rotates to prevent it from jumping.

[0026] Working principle: The paper tube conveying mechanism moves the paper tube from the previous station to the inkjet printing mechanism, which then sprays ink onto the inner walls of both ends of the paper tube to cover the original markings. After the process is complete, the paper tube conveying mechanism sends the paper tube to the next station.

[0027] The conveyor motor 7 drives the lead screw to move horizontally, and the lifting motor drives the Z-axis linear module to move vertically. The front and rear inkjet mechanisms move into position. Each station has a set of inkjet guns. When the paper tube enters the station, the front and rear inkjet guns move forward, the upper pressure roller descends to press down on the paper tube, the rolling motor 24 drives the paper tube 3 to rotate, and at the same time the inkjet guns spray ink onto the inner wall of the paper tube. The inkjet spraying ends after the rolling motor 24 rotates one revolution.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
