Description

Technical Field

[0001] This utility model relates to the field of heat shrink tape inkjet printing technology, and in particular to a fully automatic inkjet printing device for the surface of heat shrink tape. Background Technology

[0002] Heat shrink tape features high-temperature shrinkage, flexibility, flame retardancy, insulation, and corrosion protection. It is widely used for insulation protection of various wire harnesses, solder joints, and inductors, as well as for rust and corrosion prevention of metal tubes and rods. Since product marking is a means of complying with regulations, manufacturers typically spray-code the surface of the heat shrink tubing to indicate batch numbers, model specifications, and other information.

[0003] Traditional heat shrink tubing marking methods often rely on manual operation or marking devices. Manual operation is not only inefficient, but also makes it difficult to guarantee the marking quality. Existing marking devices lack the function of limiting the heat shrink tubing, which makes the heat shrink tubing prone to slippage and deviation during feeding, resulting in misalignment of the marking position, affecting the overall appearance and readability of the product, and the overall adaptability is not good. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully automatic inkjet printing device for the surface of heat shrinkable tape.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic inkjet printing device for heat shrink tape surface includes an inkjet printer body, an inkjet printing head connected to the inkjet printer body, and further includes:

[0007] Base plate;

[0008] The first fixed frame is fixed to the upper middle part of the base plate, the inkjet printer body is installed on the top of the first fixed frame, and the inkjet nozzle is installed on the inner top wall of the first fixed frame.

[0009] Two second fixing frames are fixed to the upper end of the base plate and are symmetrically arranged on both sides of the first fixing frame. The inner side of each of the two second fixing frames is provided with a feeding mechanism. The inner top wall of the second fixing frame is provided with a mounting groove, and the inside of the mounting groove is provided with a limiting mechanism.

[0010] As a further improvement of this utility model, the feeding mechanism includes a lower feeding roller disposed inside the second fixed frame. Both ends of the lower feeding roller are rotatably connected to the inner side wall of the second fixed frame. The inner side of the second fixed frame is provided with a mounting frame located above the lower feeding roller. The inner side of the mounting frame is provided with an upper feeding roller. Both ends of the upper feeding roller are rotatably connected to the inner side wall of the mounting frame. A motor is fixedly installed on the outer side wall of the mounting frame. The output shaft of the motor passes through the mounting frame and is fixed to the end of the upper feeding roller. An electric telescopic rod is installed on the top of the second fixed frame. The telescopic end of the electric telescopic rod passes downward through the second fixed frame and is fixed to the top of the mounting frame.

[0011] As a further improvement of this utility model, the limiting mechanism includes a bidirectional threaded rod disposed inside the mounting groove. Limiting plates are threadedly sleeved on the side walls near both ends of the bidirectional threaded rod. The limiting plates are slidably connected inside the mounting groove. One end of the bidirectional threaded rod is rotatably connected to the inner wall of the mounting groove. The other end of the bidirectional threaded rod is fixed with a connecting rod. The end of the connecting rod away from the bidirectional threaded rod passes through the inner wall of the mounting groove and is connected to a rotating structure.

[0012] As a further improvement of this utility model, the rotating structure includes a turntable fixedly connected to the end of the connecting rod, and a crank handle is rotatably connected to the edge of the turntable.

[0013] As a further improvement of this utility model, a locking bolt is threaded through the top of the second fixing frame and is connected to it, and the locking bolt abuts against the connecting rod.

[0014] As a further improvement of this utility model, the mounting groove is a rectangular groove.

[0015] The beneficial effects of this utility model are:

[0016] By setting up a feeding mechanism, the upper feeding roller can be moved by extending and retracting the electric telescopic rod, and the distance between the upper and lower feeding rollers can be flexibly adjusted to adapt to the feeding of heat shrinkable tape of different thicknesses, thus having good adaptability.

[0017] By setting a limiting mechanism, two limiting plates can limit and guide the heat shrink tape from both sides when it is fed, so that the heat shrink tape will not slide or deviate at will, ensuring the stability of the heat shrink tape position, thereby ensuring the accuracy of the subsequent heat shrink tape coding position and ensuring good coding quality. Moreover, the distance between the two limiting plates can be flexibly adjusted to adapt to heat shrink tapes of different widths, making it highly adaptable. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-3 An automatic inkjet printing device for heat shrinkable tape surface includes an inkjet printer body 3, an inkjet printing port 4 connected to the inkjet printer body 3, and further includes:

[0024] Base plate 1;

[0025] The first fixed frame 2 is fixed to the upper middle part of the base plate 1. The inkjet printer body 3 is installed on the top of the first fixed frame 2, and the inkjet printer head 4 is installed on the inner top wall of the first fixed frame 2.

[0026] Two second fixing frames 5 are fixed to the upper end of the base plate 1, and the two second fixing frames 5 are symmetrically arranged on both sides of the first fixing frame 2. The inner side of each of the two second fixing frames 5 is provided with a feeding mechanism. The inner top wall of the second fixing frame 5 is provided with an installation groove, which is a rectangular groove. The inside of the installation groove is provided with a limiting mechanism.

[0027] In this utility model, the feeding mechanism includes a lower feeding roller 9 disposed inside the second fixed frame 5. Both ends of the lower feeding roller 9 are rotatably connected to the inner side wall of the second fixed frame 5. The inner side of the second fixed frame 5 is provided with a mounting frame 8 located above the lower feeding roller 9. The inner side of the mounting frame 8 is provided with an upper feeding roller 12. Both ends of the upper feeding roller 12 are rotatably connected to the inner side wall of the mounting frame 8. A motor 11 is fixedly installed on the outer side wall of the mounting frame 8. The output shaft of the motor 11 passes through the mounting frame 8 and is fixed to the end of the upper feeding roller 12. An electric telescopic rod 6 is installed on the top of the second fixed frame 5. The telescopic end of the electric telescopic rod 6 passes downward through the second fixed frame 5 and is fixed to the top of the mounting frame 8. The upper feeding roller 12 can be moved by the telescopic extension and retraction of the electric telescopic rod 6, and the distance between the upper feeding roller 12 and the lower feeding roller 9 can be flexibly adjusted to adapt to the feeding of heat shrinkable tape of different thicknesses.

[0028] The limiting mechanism includes a bidirectional threaded rod 13 disposed inside the mounting groove. Limiting plates 10 are threadedly fitted onto the side walls of the bidirectional threaded rod 13 near both ends. The limiting plates 10 are slidably connected inside the mounting groove. One end of the bidirectional threaded rod 13 is rotatably connected to the inner wall of the mounting groove, and the other end of the bidirectional threaded rod 13 is fixedly connected to a connecting rod 14. The end of the connecting rod 14 away from the bidirectional threaded rod 13 penetrates the inner wall of the mounting groove and is connected to a rotating structure. The rotating structure includes a turntable 15 fixedly connected to the end of the connecting rod 14. A crank handle 16 is rotatably connected to the edge of the turntable 15. By cranking the crank handle 16, the connecting rod 14 and the bidirectional threaded rod 13 can be driven to rotate more conveniently, facilitating operation. The top of the second fixing frame 5 penetrates... A locking bolt 17 is provided and is screwed to the connecting rod 14. The locking bolt 17 abuts against the connecting rod 14. By tightening the locking bolt 17, the connecting rod 14 can be firmly fixed, thereby ensuring the stability of the bidirectional threaded rod 13 and preventing the bidirectional threaded rod 13 from loosening and rotating. This also ensures the stability of the position of the limiting plate 10. When it is necessary to adjust the distance between the two limiting plates 10, the locking bolt 17 is loosened first, and then the turntable 15 is driven to rotate by the crank handle 16, which drives the connecting rod 14 to rotate. The connecting rod 14 drives the bidirectional threaded rod 13 to rotate. Since the threads on both sides of the bidirectional threaded rod 13 are opposite, the two limiting plates 10 can move synchronously, thereby adjusting the distance between the two limiting plates 10 to accommodate heat shrinkable tapes of different widths.

[0029] In use, this utility model is achieved by clamping the heat shrinkable tape between the upper feeding roller 12 and the lower feeding roller 9, and by starting the motor 11 to drive the upper feeding roller 12 to rotate. The heat shrinkable tape is then moved by the upper feeding roller 12, allowing it to pass under the spray nozzle 4. The motor 11 is started and stopped intermittently to feed the heat shrinkable tape. When the heat shrinkable tape stops moving, the spray nozzle 4 sprays codes onto the surface of the heat shrinkable tape.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
