Technical Field
[0001] The present application relates to the technical field of printing devices, and in particular to a film printing device for ton bags. Background Art
[0002] During the printing process, existing film printing devices are usually equipped with only one scraper, and the scraper is driven by vertical lifting. This design has the following defects in practical applications:
[0003] (1) Poor printing effect: Since there is only one scraper, it is difficult to apply the ink evenly on the film. Especially when printing complex patterns, uneven ink distribution is likely to occur, affecting the final printing effect;
[0004] (2) Poor adaptability: The vertical lifting scraper drive method requires a large physical space and will interfere with the pressure frame used to fix the film, resulting in a small opening and closing clamping angle of the pressure frame, which is inconvenient for the film clamping operation. Utility Model Content
[0005] The problem to be solved by the present application is that the existing film printing device is usually equipped with only a single scraper, and the scraper is driven by vertical lifting, which not only makes it difficult to evenly scrape the ink on the upper part of the film, but also leads to the problem that the opening and closing of the press frame is limited, making it inconvenient to clamp the film.
[0006] In order to solve the above technical problems, the present application provides a film printing device for ton bags, including a stand, a support frame for supporting the film is arranged on the upper part of the stand, a scraper assembly for adjusting the height by swinging is arranged on one side of the stand, the scraper assembly includes a column, the column is connected to the stand through a bearing seat, a pressure frame for cooperating with the support frame to abut the film is arranged on one side of the column, the scraper assembly also includes a cross column, the cross column is vertically and fixedly arranged on the top of the column, a scraper member for scraping ink and a linear member for driving the scraper member to move linearly back and forth are arranged inside the cross column, and a driving member for pulling the bottom end of the column for swinging operation is arranged on the upper part of the frame.
[0007] Since the printing device of the present application is designed to be composed of a scraper part, a linear motion part and a driving part, it is possible to achieve a uniform reciprocating coating operation of the ink through the scraper part and the linear motion part, and to achieve a convenient spatial flipping operation of the scraper part and the linear motion part through the driving part, thereby solving the problem that the film printing device of the prior art is usually only equipped with a single scraper, and the scraper is driven by vertical lifting, which not only makes it difficult to evenly scrape the ink on the upper part of the film, but also causes the opening and closing of the pressure frame to be restricted, making it inconvenient to clamp the film.

DETAILED DESCRIPTION
[0014] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application. Example
[0015] This application relates to a film printing device for ton bags, such as Figure 1-5 As shown, the printing device includes a stage 6, a support frame 5 for supporting the film is arranged on the upper part of the stage 6, and a scraper assembly for adjusting the height by swinging is arranged on one side of the stage 6. The scraper assembly includes a column 3, which is connected to the stage 6 through a bearing seat, and a pressure frame 4 for cooperating with the support frame 5 to abut the film is arranged on one side of the column 3. The scraper assembly also includes a cross column 1, which is vertically and fixedly arranged on the top of the column 3. A scraper member 2 for scraping ink and a linear moving member 8 for driving the scraper member 2 to move linearly back and forth are arranged inside the cross column 1. A driving member 7 for pulling the bottom end of the column 3 for swinging operation is arranged on the upper part of the frame, so that the column 3 is driven to swing around the stage 6 by means of the driving member 7, so that the scraper member 2 at one end of the column 3 and the support frame 5 can be controlled to perform synchronous spatial swing operation, and the linear moving member 8 at the lower part of the cross column 1 can drive the scraper member 2 to perform linear reciprocating ink scraping action along the arrangement direction of the cross column 1.
[0016] The driving member 7 includes a machine base 24, a first motor 23, a pull rod 22, and a rod sleeve 21. The machine base 24 serves as the supporting foundation of the entire driving member 7 and is fixedly arranged at the lower part of the platform 6 to ensure the stability of the entire driving system. The first motor 23 is fixed to one side of the machine base 24 by bolt connection, and is used to provide a power source to drive the column 3 to swing around the platform 6. The pull rod 22 is arranged between the first motor 23 and the column 3, and plays the role of traction transmission. The rod sleeve 21 is symmetrically arranged at both ends of the column 3 to facilitate the adaptive connection between the pull rod 22 and the column 3.
[0017] The linear motion member 8 includes a second motor 11, a screw 9, a screw sleeve 10, a pull plate 16, and a hanging wheel 17. The second motor 11 is the power source of the linear motion member 8 and is fixedly arranged inside the horizontal column 1. It is responsible for driving the screw 9 to rotate, thereby converting it into linear motion. The screw 9 is arranged along the length direction of the column 3 and is driven by the second motor 11 to rotate. The thread design of the screw 9 enables it to convert rotational motion into linear motion when it engages with the screw sleeve 10. The screw sleeve 10 is arranged on the upper part of the screw 9 and is engaged with the screw 9. The screw sleeve 10 moves along the axial direction of the screw 9 by following the rotation of the screw 9, thereby To achieve linear motion, the pull plate 16 is connected to the lower end of the screw sleeve 10 to carry and fix the pulley 17. The pulley 17 is arranged below the pull plate 16 to pull the scraper member 2 for linear motion. When the second motor 11 is started, it drives the screw 9 to rotate. Due to the meshing relationship between the screw 9 and the screw sleeve 10, the screw sleeve 10 will move along its axial direction as the screw 9 rotates. The pull plate 16 is connected to the screw sleeve 10, so it will also move with the movement of the screw sleeve 10. Finally, the pulley 17, as the traction component of the scraper member 2, will drive the scraper member 2 to perform linear motion as the pull plate 16 moves.
[0018] The scraper member 2 includes a frame plate 14, a slide rod 12, a sliding sleeve 13, a plate frame 19, a connecting rod 20, a hanging plate 18, and a blade plate 15. The frame plate 14 serves as the supporting structure of the entire scraper member 2. The frame plate 14 is located below the slide rod 12. It is responsible for carrying and fixing other components to ensure the stability and reliability of the entire scraper member 2. The slide rod 12 is symmetrically arranged along the length direction of the lower part of the crossbeam, providing a sliding track for the frame plate 14. This design allows the frame plate 14 to move freely on the slide rod 12, thereby Adjust the position and angle of the scraper 2. The sliding sleeve 13 is connected between the frame 14 and the slide rod 12, playing the role of sliding connection. Through the sliding sleeve 13, the frame 14 can move smoothly on the slide rod 12 without generating too much friction and resistance. There are two plate racks 19, which are respectively arranged under the frame 14 and connected by the connecting rod 20. This design not only enhances the stability of the scraper 2, but also makes the blade 15 more firmly fixed on the plate rack 19. The connecting rod 20 The two plate frames 19 are connected to ensure their synchronous movement. This design enables the two plate frames 19 to maintain consistent force and angle during the scraping process, thereby improving the scraping effect. The knife plate 15 is a key component of the scraper 2. It is responsible for directly contacting the object to be scraped. The knife plate 15 is arranged in an inclined state below the plate frame 19, and the angle between it and the plate frame 19 is 60-70°, preferably 65°. This design not only reduces the scraping resistance, but also enables the ink to be more evenly coated on the object to be scraped. The hanging plate 18 is arranged between the plate frames 19 for hanging with the hanging wheel 17. Through the action of the hanging wheel 17, the frame 14 can slide back and forth along the slide rod 12 with the help of the sliding sleeve 13, and the plate frame 19 at the bottom of the frame 14 can drive the knife plate 15 to swing slightly around the frame 14 through the control of the hanging plate 18, so that the knife plate 15 can contact the surface of the film, and then print the ink evenly on the film surface.
