Description

Technical Field

[0001] This utility model relates to the field of film printing technology, specifically to a pad printing device for film printing. Background Technology

[0002] Pad printing is a common technique used in film printing to print patterns onto the film surface. Pad printing can print text, graphics, and images on various types of film surfaces and is becoming an important specialty printing technique in the film printing industry.

[0003] Existing pad printing equipment for film typically has a pad printing head that is integrally formed with the equipment body and cannot be removed and replaced. This means that a single pad printing equipment can only perform one type of pad printing operation, which cannot meet the various complex pad printing needs in actual processing and production. Utility Model Content

[0004] The purpose of this invention is to provide a pad printing device for film printing, which has the advantage that the pad printing head can be replaced according to actual processing needs, adapting to more types of pad printing processing needs, and solving the problem that existing pad printing devices cannot meet complex pad printing needs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pad printing device for film printing, comprising a base and a pad printing mechanism located on the base, a receiving arm welded to the base, wherein an extension platform is integrally connected above the receiving arm, a cylinder is mounted on the extension platform, a telescopic column is connected below the cylinder, a mounting plate is welded to the bottom of the telescopic column, a positioning socket is formed on the mounting plate, wherein the opening of the positioning socket is located on the bottom wall and one side wall of the mounting plate, and the device is inserted into the positioning socket through the opening on the side wall of the mounting plate. The inner extension plate and the pad printing mechanism include a lower extension rod coaxially connected to the bottom of the inner extension plate and a pad printing head fixedly installed at the bottom of the lower extension rod. Both sides of the positioning socket have side grooves forming in the mounting plate. Springs are connected to the opposite sides of the two side grooves, and positioning blocks are connected between the two springs. The two positioning blocks extend into the positioning socket and abut against the inner extension plate, thereby using the two positioning blocks to limit the inner extension plate, the lower extension rod and the pad printing head. Tensioning rods are connected to the opposite sides of the two positioning blocks, and the two tensioning rods are used for hand gripping and operation.

[0006] As a preferred embodiment, two parallel reinforcing plates are fixedly installed on the inner side of the receiving arm. The reinforcing plates are designed with a 45° inclination and both sides of the reinforcing plates are fixed to the receiving arm with bolts. Thus, the two reinforcing plates are used to reinforce the structure at the turning point of the receiving arm, making the reinforcing plates, extension platform and the structure on the extension platform more stable.

[0007] As a preferred embodiment: upper sleeves are symmetrically welded on both sides of the bottom wall of the extension platform, and a lower sliding rod is slidably installed inside each of the two upper sleeves. Both lower sliding rods are welded to the mounting plate. This allows the two lower sliding rods to move up and down within the two upper sleeves when the mounting plate is raised or lowered, thereby making the mounting plate more stable during the raising and lowering process and preventing swaying.

[0008] As a preferred embodiment: the top wall, bottom wall and side wall of the inner extension plate are all in contact with the inner wall of the positioning socket; so that the inner extension plate will not shift after being constrained by the two positioning blocks.

[0009] As a preferred embodiment, the four side walls of the positioning block are all in contact with the inner wall of the side groove, so that the positioning block can only slide horizontally under the action of the spring and will not wobble.

[0010] As a preferred embodiment: the tension bar passes through the spring but does not contact the spring, and the side of the tension bar facing away from the positioning block slides out of the mounting plate; so that the tension bar can move without interfering with the spring.

[0011] As a preferred embodiment, the telescopic column, upper sleeve, and lower sliding rod are all vertically arranged, and the telescopic column is slidably connected to the bottom of the extension platform, so that the telescopic column can extend and retract smoothly.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model allows the two positioning blocks to be released from locking the inner plate by moving the two stretching rods in opposite directions. The inner plate can then be removed horizontally, and the printing head below can be replaced. This makes the printing head of the printing device replaceable according to actual processing needs, thus adapting to more types of printing processing needs.

[0014] 2. In this utility model, when the pad printing head does not meet the processing requirements, the two tension bars can be pulled to compress the two springs and cause the two positioning blocks to retract into the two side grooves. Then, the inner extension plate can be horizontally removed from the positioning socket, and the lower extension rod and the pad printing head can be removed. After that, the pad printing head can be replaced, making the replacement of the pad printing head very convenient and can be completed without the use of external tools. Attached Figure Description

[0023] Please see Figures 1 to 4This utility model provides an embodiment of a pad printing device for film printing, including a base 1 and a pad printing mechanism located on the base 1. A receiving arm 2 is welded onto the base 1. The receiving arm 2 is U-shaped. To make it more stable, two parallel reinforcing plates 3 are fixedly installed on the inner side of the receiving arm 2. The reinforcing plates 3 are designed with a 45° inclination. Both sides of the reinforcing plates 3 are fixed to the receiving arm 2 by bolts. Thus, the two reinforcing plates 3 are used to reinforce the structure at the turning point of the receiving arm 2, making the reinforcing plates 3, the extension platform 4, and the structure on the extension platform 4 more stable. The extension platform 4 is integrally connected above the receiving arm 2. A cylinder 5 is installed, with a telescopic column 6 connected below the cylinder 5. A mounting plate 7 is welded to the bottom of the telescopic column 6. Upper sleeves 8 are symmetrically welded to both sides of the bottom wall of the extension platform 4, and a sliding lower rod 9 is slidably installed inside each of the two upper sleeves 8. The two lower lower rods 9 are welded to the mounting plate 7, so that when the mounting plate 7 is raised or lowered, it can drive the two lower lower rods 9 to rise or fall within the two upper sleeves 8. Thus, the two lower lower rods 9 make the mounting plate 7 more stable when it is raised or lowered, and there will be no shaking. The telescopic column 6, the upper sleeves 8 and the lower lower rods 9 are all set vertically, and the telescopic column 6 is slidably connected to the bottom of the extension platform 4, so that the telescopic column 6 can be extended and retracted smoothly.

[0024] A positioning socket 10 is formed on the mounting plate 7. The opening of the positioning socket 10 is located on the bottom wall and one side wall of the mounting plate 7. An inner extension plate 11 is inserted into the positioning socket 10 through the opening on the side wall of the mounting plate 7. The top wall, bottom wall, and side wall of the inner extension plate 11 are all in contact with the inner wall of the positioning socket 10, so that the inner extension plate 11 will not shift after being constrained by two positioning blocks 15. The transfer printing mechanism includes a lower extension rod 16 coaxially connected to the lower part of the inner extension plate 11 and a transfer printing head 17 fixedly installed at the bottom of the lower extension rod 16. Side grooves 12 are formed on both sides of the positioning socket 10 facing into the mounting plate 7. Springs 13 are connected to the opposite sides of the two side grooves 12, and the two springs 13 are connected between them. Each is connected to a positioning block 15. Both positioning blocks 15 extend into the positioning socket 10 and abut against the inner extension plate 11, thereby using the two positioning blocks 15 to limit the inner extension plate 11, the lower extension rod 16 and the transfer head 17. The four side walls of the positioning blocks 15 are all in contact with the inner wall of the side groove 12, so that the positioning blocks 15 can only slide horizontally under the action of the spring 13 and will not wobble. On the opposite side of the two positioning blocks 15, there are two tension rods 14 connected. The two tension rods 14 are used for hand gripping and operation. The tension rods 14 pass through the spring 13 but do not contact the spring 13. The side of the tension rods 14 facing away from the positioning blocks 15 slides out from the mounting top plate 7, so that the tension rods 14 can move without conflicting with the spring 13.

[0025] Working Principle: In this invention, the printing plate with the pattern to be printed is first placed below the printing head 17. Ink is applied to the printing plate. The driving cylinder 5 moves, causing the telescopic column 6 to sink, which in turn causes the mounting plate 7 to sink along with the two sliding rods 9 until the printing head 17 covers the printing plate and prints the pattern composed of ink onto the surface of the printing head 17. Then, the cylinder 5 moves the mounting plate 7 back to its original position and removes the printing plate. The film to be printed is placed directly below the printing head 17. The driving cylinder 5 moves, causing the printing head 17 to sink again, thus transferring the pattern with ink from the printing head 17 onto the film, completing the printing process. For pad printing operations, when the shape, specifications, etc. of the pad printing head 17 do not meet the processing requirements, the two tension bars 14 can be pulled simultaneously to compress the two springs 13 and cause the two positioning blocks 15 to retract into the two side grooves 12. Then, the inner extension plate 11 can be horizontally removed from the positioning socket 10, and the lower extension rod 16 and the pad printing head 17 can be removed. After that, a new specification pad printing head 17 that meets the processing requirements can be replaced on the mounting plate 7 (the new specification pad printing head 17 still has the same two structures, the lower extension rod 16 and the inner extension plate 11), and the replacement can be completed, making the device suitable for different types of film pad printing operations.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
