Description

Technical Field

[0001] This utility model relates to the field of printing and packaging, and in particular to a feeding device for a green printing sealing machine. Background Technology

[0002] Laminating machines, as a common office and image preservation device, work by using heat-pressing technology to tightly seal a plastic film onto the surface of documents or photos. This process not only effectively isolates moisture and stains but also significantly enhances the tear resistance of documents and photos, providing reliable protection for the long-term preservation of important data. However, there is room for improvement in the feeding device of laminating machines. Currently, most of these laminating machines use conveyor belts for feeding. During the feeding process, due to the poor stability of the conveyor belt, the paper often vibrates during transport. This vibration can easily cause two or more layers of paper to overlap or misalign, affecting the lamination effect and resulting in defects such as bubbles and wrinkles in the laminated documents or photos, failing to achieve the ideal protection and aesthetic effect. Utility Model Content

[0003] In order to overcome the shortcomings of unstable feeding devices in existing medium and large-sized laminating machines, the technical problem of this utility model is to provide a green printing laminating machine feeding device that can sort laminating materials.

[0008] In a preferred embodiment of the present invention, a smooth plate is also included. The smooth plate is fixedly connected above the support frame and is located directly below the pressure plate.

[0009] In a preferred embodiment of the present invention, a labeling pad is also included, and the labeling pad is provided on the smooth plate.

Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0017] Example: A feeding device for a green printing laminator, such as... Figure 1-2 As shown, the machine includes a support frame 3, an electric slide rail 4, a first push plate 5, a controller 6, and an alignment mechanism. The right side of the sealing machine 1 has a feed inlet 2. The support frame 3 is fixedly connected to the right side of the sealing machine 1. The left end of the support frame 3 is located directly below the feed inlet 2. The electric slide rails 4 are symmetrically fixedly connected to the support frame 3. The first push plate 5 is slidably connected between the two electric slide rails 4. The moving part of the electric slide rail 4 is connected to the first push plate 5. The controller 6 is installed on the right side of the support frame 3. The controller 6 is electrically connected to the electric slide rail 4. The electric slide rail 4 is controlled to run by the controller 6. The support frame 3 is equipped with an alignment mechanism for sorting the sealing material.

[0018] like Figure 1 and Figure 3As shown, the alignment mechanism includes a gantry frame 7, an electric push rod 8, a mounting plate 9, a motor 10, a second push plate 11, a double-acting lead screw 12, a bevel gear set 13, a screw 14, a third push plate 15, and a pressure plate 16. The gantry frame 7 is fixedly connected to the middle of the support frame 3. The electric push rod 8 is fixedly connected to the top center of the gantry frame 7. A through hole is provided on the mounting plate 9, and the telescopic rod of the electric push rod 8 is slidably connected to the mounting plate 9 through the through hole. A square opening is provided on the right side of the mounting plate 9, and the second push plate 11 is symmetrically slidably connected within the square opening on the right side of the mounting plate 9. A motor 10 is fixedly connected to the rear right side of the mounting plate 9. Both the electric push rod 8 and the motor 10 are electrically connected to the controller 6. The output shaft of 10 is fixedly connected to a bidirectional lead screw 12, which is rotatably connected to the mounting plate 9. The second push plate 11 is threadedly connected to the bidirectional lead screw 12. The front side of the mounting plate 9 is rotatably connected to a screw 14, the thread of which is located on the left side. A bevel gear set 13 is provided between the right end of the screw 14 and the bidirectional lead screw 12. The left end of the screw 14 is threadedly connected to a third push plate 15, which is slidably connected to the mounting plate 9. The end of the telescopic rod of the electric push rod 8 is fixedly connected to a pressure plate 16, which is located below the mounting plate 9. A slot is provided on the right side of the square opening of the mounting plate 9. The upper right side of the pressure plate 16 has a protrusion that engages with the slot on the mounting plate 9.

[0019] like Figure 4 As shown, it also includes a ball bearing 17. The ball bearing 17 is rotatably connected inside the through hole opened on the mounting plate 9. The ball bearing 17 is used to help the mounting plate 9 slide up and down more smoothly.

[0020] like Figure 1 As shown, it also includes a sponge pad 18, and the sponge pad 18 is fixedly connected to the second push plate 11, the third push plate 15, and the pressure plate 16.

[0021] like Figure 1 As shown, it also includes a smooth plate 19. The smooth plate 19 is fixedly connected to the top of the support frame 3 and is located directly below the pressure plate 16. The surface of the smooth plate 19 is smooth, which can reduce the friction between the material and the support surface, avoid the material from getting stuck or shifting during the movement, and improve the feeding efficiency and accuracy.

[0022] like Figure 1 As shown, it also includes a labeling pad 20, which is provided on the smooth plate 19; the operator can use the labeling pad 20 to accurately place the material and ensure that the material is in the appropriate starting position for sealing.

[0023] Place the green printing material to be laminated on the smooth plate 19 above the support frame 3. The marking pad 20 on the smooth plate 19 ensures accurate placement, aligning one end of the material with the first push plate 5, placing the material in the appropriate starting position for lamination. The controller 6 activates the electric push rod 8, causing its telescopic rod to extend downwards, passing through the through-hole in the mounting plate 9 and pushing the pressure plate 16 downwards. The mounting plate 9 moves downwards under its own weight, causing the second push plate 11 to move downwards. The ball bearings 17 inside the through-hole of the mounting plate 9 contact the electric push rod 8, allowing the mounting plate 9 to slide more smoothly up and down. When the bottom of the second push plate 11 contacts the surface of the smooth plate 19... The second push plate 11 restricts the mounting plate 9 from sliding further downwards. At this time, the electric push rod 8 is turned off, and the motor 10 on the right rear side of the mounting plate 9 is started. The motor 10 drives the bidirectional lead screw 12 to rotate. Since the second push plate 11 is threadedly connected to the bidirectional lead screw 12, the rotation of the bidirectional lead screw 12 will cause the second push plate 11 to move in opposite directions along the square opening on the right side of the mounting plate 9. According to the width of the plastic sealing material, the second push plate 11 moves to allow the sponge pad 18 on the second push plate 11 to contact the material, preventing the material from being damaged due to excessive pressure, and playing a role in fixing and straightening the material. When the bidirectional lead screw 12 rotates, it drives the screw 14 to rotate through the bevel gear set 13. The third push plate 15 and the screw... The left end of rod 14 is threaded. Rotating rod 14 causes the third push plate 15 to move to the right, assisting in fixing and aligning the sealing material from the side, ensuring that the material does not shift left or right during feeding. Then, the electric push rod 8 is controlled to continue moving the pressure plate 16 downward. The pressure plate 16 presses down on the sealing material, allowing it to be organized and ensuring the quality of the sealing. After the sealing material is organized, the electric push rod 8 is controlled to retract and the motor 10 is controlled to reverse. The motor 10 drives the second push plate 11 and the third push plate 15 back to their original positions, releasing the material from the limit. The electric push rod 8 then drives the pressure plate 16 upward. When the pressure plate 16 rises, the protrusion on the upper right side of the pressure plate 16 is embedded. The corresponding slots on the mounting plate 9 clamp the mounting plate 9 to the pressure plate 16, preventing the mounting plate 9 from swinging or shifting when it rises. Then, the pressure plate 16 drives the mounting plate 9, the second push plate 11, and the third push plate 15 to rise and reset. Then, the controller 6 controls the electric slide rail 4, causing the moving part of the electric slide rail 4 to drive the first push plate 5 connected to it to slide to the left. The first push plate 5 pushes the aligned sealing material to move to the left along the smooth plate 19, so that the aligned material can smoothly enter the sealing machine 1 from the feed port 2 to start the sealing operation. Then, the controller controls the electric slide rail 4 to drive the first push plate 5 to move to the right and reset. After the sealing is completed, the material is taken out from the sealing machine 1, completing the entire sealing process.

[0024] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
