Description

Technical Field

[0001] This utility model relates to the field of printed label processing, and in particular to a printing slitting device. Background Technology

[0002] The widespread use of labels and the continuous development of label varieties have naturally driven the development of label printing technology. During label processing, multiple rows of label patterns need to be printed on paper. After printing, the paper needs to be cut into multiple strips, and then the cut strips are rolled up. For example, patent document CN223000654U discloses a cutting device for printed labels. The label is wrapped around the outside of the label roller, and the label is transported by the rotation of a servo motor. The label is transferred to the connecting roller through the label roller, and then cut by the cutting blade on the cutting roller. The cut labels need to be rolled up onto paper tubes for convenient transportation and sale. Currently, most of the time, multiple paper tubes are placed on the winding roller manually, and each label is stuck onto the paper tube. The winding roller drives the paper tube to rotate and roll it up. After a certain length, the label is cut off, and then glue is applied to the label manually. The last section of the label is then manually stuck onto the label roll to prevent the label roll from unraveling. Finally, the label roll is removed from the winding roller. Because the last glue application and winding steps are done manually, the production efficiency is difficult to improve and is unstable. Utility Model Content

[0003] The purpose of this invention is to provide a printing slitting device to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A printing slitting device includes a control unit and a slitting unit. The slitting unit includes a frame, a lifting mechanism at the top front of the frame, a mounting plate fixedly connected to the lifting power end of the lifting mechanism, a cutting mechanism at the bottom of the mounting plate, a glue box in front of the cutting mechanism, the glue box being slidably connected inside the mounting plate, multiple glue dispensing tubes fixedly connected to the bottom of the glue box, baffles slidably connected to the inner bottom wall of the glue dispensing tubes, and an elastic reset mechanism inside the glue dispensing tubes for moving and resetting the baffles. Elastic connecting mechanisms are fixedly attached to both sides of the glue box and fixedly attached to the bottom of the mounting plate. Limiting plates are fixedly attached to both sides of the glue box and rest on the top of the mounting plate. A material guiding mechanism is provided below the glue box.

[0006] Preferably, the elastic reset mechanism includes a movable plate, which is fixedly connected to the top of the baffle. A guide rod is fixedly connected inside the glue box. The movable plate is slidably connected to the guide rod. A first spring is sleeved on the guide rod. The first spring is fixedly connected between the movable plate and the inner wall of the glue box. A pressure plate is fixedly connected to the rear side of the movable plate. The pressure plate extends from the rear side of the glue box and has an inclined surface at its rear end.

[0007] Preferably, the cutting mechanism includes a blade holder, which is fixedly connected to the bottom of the mounting plate. A cutting blade is fixedly connected to the bottom of the blade holder, and an extrusion block is fixedly connected to the front side of the blade holder. The extrusion block has a bevel at its front end.

[0008] Preferably, the elastic connection mechanism includes a sleeve, which is fixedly connected to the bottom of the mounting plate. A movable rod is slidably connected inside the sleeve. A second spring is fixedly connected between the top of the movable rod and the inner wall of the sleeve. A pressure block is fixedly connected to the bottom of the movable rod. The pressure block is fixedly connected to the side of the glue box, and the bottom surface of the pressure block is lower than the bottom surface of the glue dispensing tube.

[0009] Preferably, the lifting mechanism includes a support plate, which is fixedly connected to the top of the frame. A U-shaped frame is fixedly connected to the top of the support plate, and an electric push rod is fixedly connected to the inner top wall of the U-shaped frame. The output end of the electric push rod is fixedly connected to the mounting plate.

[0010] Preferably, the material guiding mechanism includes a fixed seat, which is fixedly connected to the top of the support plate. Material guiding rollers are rotatably connected to the front and rear sides of the top of the fixed seat, and a cutting groove is provided on the top of the fixed seat.

[0011] The beneficial effects are as follows: when the label is wound to a certain length, the mounting plate moves down, causing the cutting mechanism and the glue box to move down. After the glue box moves down a certain distance, the elastic connecting mechanism first presses down the label. At this time, the glue box no longer moves down. The cutting mechanism continues to move down and squeezes the elastic reset mechanism. The elastic reset mechanism drives the baffle to move, connecting the glue outlet tube. Then the glue flows onto the label through the glue outlet tube. At the same time, the cutting mechanism cuts the label, realizing automatic cutting and automatic glue application. This can save manual operation, improve efficiency, and make production efficiency more stable.

They 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. Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-7As shown, a printing slitting device includes a control unit 1 and a slitting unit 2. The slitting unit 2 includes a frame 201. A slitting roller 202, a first discharge roller 203, a second discharge roller 204, and a take-up roller 205 are rotatably mounted inside the frame 201. A lifting mechanism 3 is provided at the top front end of the frame 201, located between the second discharge roller 204 and the take-up roller 205. A mounting plate 4 is fixedly connected to the lifting power end of the lifting mechanism 3. A cutting mechanism 8 is provided at the bottom of the mounting plate 4. A glue box 5 is provided in front of the cutting mechanism 8 and is slidably connected inside the mounting plate 4. A component is fixedly connected to the bottom of the glue box 5. Multiple dispensing tubes 501 are provided. A baffle 502 is slidably connected to the inner bottom wall of each dispensing tube 501. An elastic reset mechanism 6 is provided inside the dispensing tube 501 to drive the baffle 502 to move and reset. Elastic connecting mechanisms 7 are fixed on both sides of the glue box 5. The elastic connecting mechanisms 7 are fixed to the bottom of the mounting plate 4. By setting the elastic connecting mechanisms 7, the mounting plate 4 can drive the glue box 5 to move downward. When the glue box 5 can no longer move downward, the mounting plate 4 can continue to move downward relative to the glue box 5. Limiting plates 503 are fixedly connected to both sides of the glue box 5. The limiting plates 503 rest on the top of the mounting plate 4. A material guiding mechanism 9 is provided below the glue box 5.

[0026] The elastic reset mechanism 6 includes a movable plate 601, which is fixedly connected to the top of the baffle 502. The movable plate 601 is used to drive the baffle 502 to move. When the baffle 502 moves forward, the glue outlet tube 501 communicates with the inside of the glue box 5, and the glue in the glue box 5 flows out through the glue outlet tube 501. The inside of the glue box 5 is connected to a guide rod 602 by screws. The movable plate 601 is slidably connected to the guide rod 602. The guide rod 602 is used to limit and guide the movable plate 601. A first spring 603 is sleeved on the guide rod 602. The first spring 603 is fixedly connected between the movable plate 601 and the inner wall of the glue box 5. The first spring 603 is used to move the movable plate 601 backward to reset. A pressure plate 604 is connected to the rear side of the movable plate 601 by screws. The pressure plate 604 extends from the rear side of the glue box 5, and the rear end of the pressure plate 604 is provided with an inclined surface.

[0027] The cutting mechanism 8 includes a knife holder 801, which is connected to the bottom of the mounting plate 4 by screws. A cutter 802 is connected to the bottom of the knife holder 801 by screws. An extrusion block 803 is connected to the front side of the knife holder 801 by screws. The front end of the extrusion block 803 is provided with a bevel. When the glue box 5 stops moving down and the knife holder 801 continues to move down, the extrusion block 803 will push the pressure plate 604 forward. The pressure plate 604 will drive the movable plate 601 and the baffle 502 to move forward, thereby achieving glue application. At the same time, the cutter 802 will cut the label.

[0028] The elastic connection mechanism 7 includes a sleeve 701, which is connected to the bottom of the mounting plate 4 by screws. A movable rod 702 is slidably connected inside the sleeve 701. A second spring 703 is fixedly connected between the top of the movable rod 702 and the inner wall of the sleeve 701. A pressure block 704 is welded to the bottom of the movable rod 702. The pressure block 704 is connected to the side of the glue box 5 by screws. The second spring 703 is always in a compressed state. Therefore, in its natural state, the second spring 703 always applies a downward force to the movable rod 702, which causes the pressure block 704 to apply a downward force to the glue box 5, thereby pressing the limiting plate 503 against the top of the mounting plate 4. This ensures that the mounting plate 4 moves down while driving the glue box 5 to move down stably. The bottom surface of the pressure block 704 is lower than the bottom surface of the glue dispensing tube 501. Therefore, the pressure block 704 will contact the fixing seat 901 before the glue dispensing tube 501. At this time, the glue box 5 cannot continue to move down. This creates a small distance between the glue dispensing tube 501 and the label, ensuring that the glue can flow out smoothly.

[0029] The lifting mechanism 3 includes a support plate 301, which is connected to the top of the frame 201 by screws. A U-shaped frame 302 is connected to the top of the support plate 301 by screws. An electric push rod 303 is connected to the inner top wall of the U-shaped frame 302 by bolts. The output end of the electric push rod 303 is fixedly connected to the mounting plate 4.

[0030] The material guiding mechanism 9 includes a fixed seat 901, which is fixedly connected to the top of the support plate 301. The front and rear sides of the top of the fixed seat 901 are rotatably connected to the material guiding rollers 902. A cutting groove 903 is opened on the top of the fixed seat 901, which is located directly below the cutter 802.

[0031] Working principle: The paper tube for winding is placed on the winding roller 205. After the label is cut by the slitting roller 202, it passes over the top of the first discharge roller 203, then over the bottom of the second discharge roller 204, and then passes over the top of the fixed seat 901. The two guide rollers 902 guide the label. Finally, the label is wound around the paper tube from the bottom of the winding roller 205 to form a label roll. In this process, both the slitting roller 202 and the winding roller 205 are driven by the control unit 1. The structure and principle of the control unit 1 are existing technologies. The control unit 1 can be purchased directly on the market and will not be described in detail here. When the label on the paper tube is wound to a certain length, the winding roller 205 pauses. Then, the electric push rod 303 drives the mounting plate 4 to move downwards. The mounting plate 4 drives the glue box 5 and the knife holder 801 to move downwards together. The pressure block 704 will first press on the fixed seat 901. Since the pressure block 704 and the glue box 5 are fixedly connected, the glue box 5 will not continue to move downwards at this time. Then, the mounting plate 4 continues to drive the knife holder 801 to move downwards. The pressing block 803 will press the pressure plate 604 forward. 4. The movable plate 601 moves forward, the first spring 603 is compressed, and the movable plate 601 moves the baffle 502 forward. At this time, the glue outlet tube 501 is connected to the glue box 5. The glue in the glue box 5 flows from the glue outlet tube 501 onto the label. At the same time, the cutter 802 cuts the label. Then the mounting plate 4 moves up and resets. The first spring 603 also rebounds and pushes the movable plate 601 to reset. The baffle 502 blocks the glue outlet tube 501 again, so that the winding roller 205 can continue to rotate for winding.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
