Description
Technical Field
[0001] This utility model belongs to the field of cigarette production technology, and in particular relates to a glue-free overlapping device for tipping paper. Background Technology
[0002] When replacing old and new paper trays in a cigarette rolling machine, the paper strip from the new tray needs to be connected to the paper strip on the old tray and fed together into the paper feeding channel to ensure a continuous supply of paper strips. Currently, most cigarette rolling equipment in China still uses adhesive tape to achieve this connection, but this method relies on manual operation and requires manual placement of the tape in advance. Due to inconsistent bonding results, paper strip breakage frequently occurs, leading to wasted time for re-threading and thus affecting production efficiency. Summary of the Invention
[0003] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a glue-free overlapping device for cork paper, further comprising:
[0004] Base plate;
[0005] A paper feeding mechanism for unwinding a paper tray, the paper feeding mechanism including an I-beam plate rotatably mounted on a base plate, and unwinding roller A and unwinding roller B fixedly mounted on the I-beam plate;
[0006] The pressing mechanism, which is set on the base plate, is used to press the paper strips released from the two paper rolls mounted on the unwinding rollers A and B.
[0007] An acceleration mechanism is located on the right side of the pressing mechanism. An acceleration roller is rotatably mounted on the acceleration mechanism to accelerate the linear speed of the paper tape to be pressed.
[0008] The power module provides power for the rotation of the I-beam disc and the operation of the pressing mechanism;
[0009] The paper guiding mechanism, which is set on the I-beam plate, is used to guide the direction of the paper tape.
[0010] Furthermore, the paper guiding mechanism includes:
[0011] Tensioning roller group A is rotatably mounted on the I-beam plate. Tensioning roller group A has multiple tensioning rollers. Several tensioning rollers of tensioning roller group A are located on both sides of unwinding roller A and are used to tension the paper strip on the paper tray on unwinding roller A.
[0012] Tensioning roller group B is rotatably mounted on the I-beam plate. Tensioning roller group B also has multiple tensioning rollers. Several tensioning rollers of tensioning roller group B are located on both sides of unwinding roller B and are used to tension the paper strip on the paper tray on unwinding roller B.
[0013] The correction mechanism is set on the base plate and is located between the I-beam and the pressing mechanism. It is used to correct the paper tape released from the paper trays on the unwinding rollers A and B.
[0014] The guiding mechanism, which is set on the base plate, is used to guide the paper tape output from tension roller group A or tension roller group B toward the correction mechanism.
[0015] Furthermore, the correction mechanism includes:
[0016] Two correction rollers are fixedly connected to the base plate and are spaced apart vertically. The interval between the two correction rollers corresponds to the inlet of the pressing mechanism.
[0017] The guide roller is fitted with two spaced-apart guide rings, the spacing between which matches the width of the paper tape.
[0018] Furthermore, the retaining ring and the correction roller are detachably connected by screws.
[0019] Furthermore, the guiding mechanism includes:
[0020] The guide rollers are fixedly connected to the base plate and are arranged at intervals, with the interval between the two guide rollers corresponding to the interval between the two correction rollers.
[0021] Furthermore, it also includes:
[0022] The paper slot is hollow, and the paper slot is formed through the end face of the acceleration roller. The paper slot is connected to the hollow part of the acceleration roller.
[0023] The beneficial effects of this utility model are as follows:
[0024] 1. By setting up a rotating I-beam disc, unwind roller A, unwind roller B and a pressing mechanism, it is convenient to press the paper strip between the new and old paper rolls. The rotating setting of the I-beam disc also makes it convenient to replace the paper roll repeatedly.
[0025] 2. By setting up tension roller group A and tension roller group B, the paper tape is supported for conveying. At the same time, when the I-beam is flipped, the paper tape will not detach from the tension roller, resulting in strong overall stability.
[0026] 3. By setting up a correction roller and retaining rings, the paper tape will pass through the correction roller before entering the pressing mechanism. The paper tape passes through the gap between the two retaining rings, so that the two retaining rings cooperate with the two sides of the paper tape to correct the paper tape, resulting in better conveying effect and preventing the paper tape from falling off or deviating.
[0027] 4. Since the retaining ring and the correction roller are detachably connected by screws, it is convenient to disassemble and install the retaining ring, making it easy to maintain and replace. At the same time, retaining rings of different thicknesses can be replaced, so that the distance between the two retaining rings can be reduced or increased, making it easy to adapt to paper tapes of different widths.
[0028] 5. By setting guide rollers, the position of the paper tape is easily guided, so that the position of the paper tape corresponds to the alignment roller, resulting in better paper tape conveying effect.
[0029] 6. By setting up a paper slot, it is convenient to insert the paper tape into the paper slot of the acceleration roller when connecting the paper tape and the acceleration roller, thereby facilitating the fixed connection between the paper tape and the acceleration roller.

Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings indicate similar items, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings. Example 1
[0039] This embodiment provides a glue-free overlapping device for cork paper, characterized in that it further includes:
[0040] Base plate 1;
[0041] The paper feeding mechanism is used to unwind the paper tray. The paper feeding mechanism includes an I-shaped tray 2 rotatably mounted on the base plate 1. An unwinding roller A3 and an unwinding roller B4 are fixedly mounted on the I-shaped tray 2.
[0042] The pressing mechanism 5 is set on the base plate 1 and is used to press the paper strips released from the two paper rolls sleeved on the unwinding rollers A3 and B4.
[0043] An acceleration mechanism 6 is located on the right side of the pressing mechanism 5. An acceleration roller 7 is rotatably mounted on the acceleration mechanism 6, which is used to accelerate the linear speed of the paper tape to be pressed.
[0044] The power module 8 provides power for the rotation of the I-beam disc 2 and the operation of the pressing mechanism 5;
[0045] The paper guiding mechanism, which is set on the I-beam plate 2, is used to guide the direction of the paper tape.
[0046] Unwinding roller A3 and unwinding roller B4 can be air-expanded shafts to press against the inner sleeve of the paper tray when it is being rolled up.
[0047] The working principles of the crimping mechanism 5 and the power module 8 are existing technologies and will not be elaborated upon here. The crimping mechanism 5 generally includes:
[0048] Two pressing rollers 15 are provided, and the two pressing rollers 15 are rotatably disposed in the pressing mechanism 5, and the two pressing rollers 15 are arranged vertically at intervals.
[0049] A pressure plate 16 is fixedly disposed on the outside of the pressing roller 15. The outer surface of the pressure plate 16 has embossing, and the embossing of the pressure plates 16 of the two pressing rollers 15 is matched.
[0050] When the pressing plate 16 of the upper pressing roller 15 faces downward, the embossing of the pressing plate 16 of the lower pressing roller 15 faces upward and is in contact with the embossing of the pressing plate 16 of the upper pressing roller 15. The transmission ratio of the two pressing rollers 15 is 1:1, and the two pressing rollers 15 rotate synchronously through the gear set in the pressing mechanism 5.
[0051] In this technical solution, it is assumed that there is a paper tray in use on the unwinding roller A3. The paper strip on the paper tray on the unwinding roller A3 passes through the paper guiding mechanism-pressing mechanism 5 in sequence and enters the machine of the next process. The tension of the paper strip is provided by the machine of the next process.
[0052] like Figure 5 , 6 As shown in Figure 7, during the paper tape feeding, the pressure plate 16 of the upper pressing roller 15 of the pressing machine mechanism is set upward, and the pressure plate 16 of the lower pressing roller 15 is set downward, so that a gap is formed between the two pressing rollers 15. When the paper tape enters the pressing mechanism 5, it passes through the gap and is output without cooperating with the pressing mechanism 5.
[0053] When the paper roll on unwind roller A3 is almost used up, a new paper roll is placed on unwind roller B4. The paper strip of the paper roll on unwind roller B4 is pulled out, passes through the paper guiding mechanism, and enters the gap of the pressing mechanism 5. At this time, the paper strip of the paper roll on unwind roller B4 is located below the paper strip of unwind roller A3. Then, the paper strip of the paper roll on unwind roller B4 is pulled into the acceleration roller 7 of the acceleration mechanism 6 after passing through the pressing mechanism 5, so that one end of the paper strip of the paper roll on unwind roller B4 is fixedly connected to the acceleration roller 7.
[0054] A motor (not shown in the figure) for driving the acceleration roller 7 to rotate is provided on the outer side of the base plate 1. After one end of the paper strip on the unwinding roller B4 is fixedly connected to the acceleration roller 7, the motor is started to make the acceleration roller 7 rotate, thereby driving the paper strip on the unwinding roller B4 to be conveyed, thereby accelerating the linear speed of the paper strip on the unwinding roller B4.
[0055] After the linear speed of the paper strip on the unwinding roller B4 reaches the same as the linear speed of the paper strip on the unwinding roller A3, the pressing mechanism 5 is activated. The pressing mechanism 5 drives the two pressing rollers 15 to rotate, so that the pressing plate 16 of the upper pressing roller 15 rotates to face downwards, and the embossing of the pressing plate 16 of the lower pressing roller 15 faces upwards and fits against the embossing of the pressing plate 16 of the upper pressing roller 15, thereby pressing the two paper strips located in the pressing mechanism 5 together.
[0056] At this time, the section of the paper tape on the unwinding roller B4 from the pressing mechanism 5 to the accelerating roller 7 is cut off by the pressing mechanism 5. The cut end of the paper tape on the unwinding roller B4 is in contact with the paper tape on the unwinding roller A3, and the paper tape continues to be conveyed, thereby playing the role of replacing the paper tape.
[0057] When the paper tray on the unwind roller B4 is almost used up, the power module 8 is started to drive the I-beam 2 to rotate. The rotation axis of the I-beam 2 is located at the center of the I-beam 2, thereby driving the unwind roller A3 and the unwind roller B4 to rotate 180° around the rotation axis of the I-beam 2.
[0058] The appearance after rotation is as follows Figure 7 As shown, at this time, the unwinding roller B4 is located at the original position of the unwinding roller A3, and the unwinding roller A3 is located at the original position of the unwinding roller B4. Then, a new paper tray is placed on the unwinding roller A3, and the paper strip of the paper tray on the unwinding roller A3 is pulled out and enters the gap of the pressing mechanism 5 after passing through the paper guiding mechanism. At this time, the paper strip of the paper tray on the unwinding roller A3 is located below the paper strip of the unwinding roller B4. Then, the paper strip of the paper tray on the unwinding roller A3 is pulled into the accelerating roller 7 of the accelerating mechanism 6 after passing through the pressing mechanism 5, so that one end of the paper strip of the paper tray on the unwinding roller A3 is fixedly connected to the accelerating roller 7.
[0059] After one end of the paper strip on the unwinding roller A3 is fixedly connected to the acceleration roller 7, the motor is started to make the acceleration roller 7 rotate, thereby driving the paper strip on the unwinding roller A3 to be conveyed, thereby accelerating the linear speed of the paper strip on the unwinding roller A3.
[0060] After the linear speed of the paper strip on the unwinding roller A3 reaches the same as the linear speed of the paper strip on the unwinding roller B4, the pressing mechanism 5 is activated. The pressing mechanism 5 drives the two pressing rollers 15 to rotate, so that the pressing plate 16 of the upper pressing roller 15 rotates to face downwards, and the embossing of the pressing plate 16 of the lower pressing roller 15 faces upwards and fits against the embossing of the pressing plate 16 of the upper pressing roller 15, thereby pressing the two sections of paper strip located in the pressing mechanism 5 together.
[0061] At this time, the section of the paper tape on the unwinding roller A3 from the pressing mechanism 5 to the accelerating roller 7 is cut off by the pressing mechanism 5. The cut end of the paper tape on the unwinding roller A3 is in contact with the paper tape on the unwinding roller B4, and the paper tape continues to be conveyed, repeating the cycle to replace the paper tape.
[0062] This structural design, with its rotating I-beam disc 2, unwinding roller A3, unwinding roller B4, and pressing mechanism 5, facilitates the pressing of paper strips between new and old paper rolls. The rotating I-beam disc 2 also allows for the cyclical replacement of paper rolls. Example 2
[0063] This embodiment provides a glue-free overlapping device for cork paper, which, in addition to the technical solutions of the above embodiments, also has the following technical features.
[0064] Furthermore, the paper guiding mechanism includes:
[0065] Tensioning roller group A9 is rotatably mounted on I-beam plate 2. Tensioning roller group A9 has multiple tensioning rollers. Several tensioning rollers of tensioning roller group A9 are located on both sides of unwinding roller A3 and are used to tension the paper strip of the paper tray on unwinding roller A3.
[0066] Tensioning roller group B10 is rotatably mounted on I-beam plate 2. Tensioning roller group B10 also has multiple tensioning rollers. Several tensioning rollers of tensioning roller group B10 are located on both sides of unwinding roller B4 and are used to tension the paper strip of the paper tray on unwinding roller B4.
[0067] The correction mechanism is set on the base plate 1. The correction mechanism is located between the I-beam plate 2 and the pressing mechanism 5. It is used to correct the paper tape released from the paper trays on the unwinding rollers A3 and B4.
[0068] The guiding mechanism, which is mounted on the base plate 1, is used to guide the paper tape output from the tension roller group A9 or the tension roller group B10 toward the correction mechanism.
[0069] In this technical solution, in tension roller group A9 and tension roller group B10, multiple tension rollers are arranged vertically on the left side of tension roller group A9, and multiple tension rollers are arranged vertically on the right side of tension roller group B10. This design ensures that the paper tape will not detach from the tension rollers when the I-beam 2 is flipped.
[0070] Through this structural design, the tension roller group A9 and tension roller group B10 are set up to support the conveying of the paper tape. At the same time, when the I-beam 2 is flipped, the paper tape will not detach from the tension roller, resulting in strong overall stability. Example 3

[0072] Furthermore, the correction mechanism includes:
[0073] Two correction rollers 11 are fixedly connected to the base plate 1 and are spaced apart vertically. The interval between the two correction rollers 11 corresponds to the inlet of the pressing mechanism 5.
[0074] The guide roller 11 is fixedly fitted with two spaced-apart guide rings 12, the spacing between the two guide rings 12 matching the width of the paper tape.
[0075] With this structural design, by setting up the correction roller 11 and the retaining ring 12, the paper tape will pass through the correction roller 11 before entering the pressing mechanism 5. The paper tape passes through the gap between the two retaining rings 12, so that the two retaining rings 12 cooperate with the two sides of the paper tape to correct the paper tape, thereby improving the conveying effect and preventing the paper tape from falling off or deviating. Example 4

[0077] Furthermore, the retaining ring 12 and the straightening roller 11 are detachably connected by screws.
[0078] With this structural design, the retaining ring 12 and the correction roller 11 are detachably connected by screws, which makes it easy to disassemble and install the retaining ring 12 for maintenance and replacement. At the same time, retaining rings 12 of different thicknesses can be replaced, so that the distance between the two retaining rings 12 can be reduced or increased, making it easy to adapt to paper tapes of different widths.

[0082] This structural design incorporates a guide roller 13, which facilitates the guidance of the paper tape's position, ensuring that the paper tape's position corresponds to the alignment roller 11, thus improving the paper tape's conveying effect. Example 6
