Description

Technical Field

[0001] The present invention relates to the technical field of paper tube production equipment, and in particular to a paper tape slitting and conveying device. Background Art

[0002] Paper products are gradually replacing plastic products due to their easy recycling and low pollution. Paper tubes are tube-shaped objects made from paper tapes. In recent years, the demand for thin paper tubes in various industries has increased sharply. For example, paper tubes can be used in tobacco products as wrappers for tobacco products or other functional structures.

[0003] At present, paper tubes are usually made by paper tube forming machines through automated processing. However, most of the paper tube forming machines in the prior art are single-channel paper tube production (only one paper tube can be produced at a time), which has limited efficiency. Multi-track paper tube synchronous forming (synchronous production of multiple paper tubes at a time) can greatly increase the upper limit of paper tube production and meet the growing consumer demand.

[0004] The use of multi-track paper tube synchronous forming requires the simultaneous provision of multiple paper tapes during feeding. If multiple paper rolls are unwound simultaneously for paper tape feeding, although it can meet the feeding needs of multiple paper tapes, the stability of multiple paper tapes is poor during long-distance transportation, and the synchronous forming effect is poor. Summary of the invention

[0005] In view of the fact that paper tube forming machines in the prior art are mostly single-channel paper tube production, which cannot meet the synchronous production requirements of multiple paper tubes.

[0024] The present invention provides a paper tape slitting and conveying device, which includes an unwinding module, a paper tape slitting module, and a paper tape guiding and separating module; the unwinding module is used to install and place a paper roll; the paper tape slitting module is located at the rear side of the unwinding module, and is used to slit the paper tape into multiple small paper tapes; the paper tape guiding and separating module is located at the rear side of the paper tape slitting module, and is used to guide and separate each of the small paper tapes after slitting. The paper tape slitting and conveying device is provided with the paper tape slitting module, so that the paper tape provided by the unwinding module can be slit; and the paper tape guiding and separating module is also provided, so that the small paper tapes after slitting can be guided, and the distance between each small paper tape can be adjusted, so as to avoid the problem of entanglement between the small paper tapes during the transmission process. The paper tape slitting and conveying device can stably convey the small paper tapes to the rear side, so as to ensure the synchronous forming effect of the subsequent small paper tapes.

[0025] Please refer to Figures 1 to 5 In one embodiment, a paper tape slitting and conveying device 100 is provided, which is mainly used to slitting and conveying paper tapes to provide a plurality of small paper tapes to a paper tube forming machine to meet the needs of the paper tube forming machine for synchronous production of multiple paper tubes.

[0026] The paper tape slitting and conveying device 100 includes an unwinding module 10, a paper tape slitting module 20, and a paper tape guiding and separating module 30. The unwinding module 10 is used to install and place a paper roll, wherein the paper roll is wound by a paper tape 200, and the paper tape 200 can be a multiple-width paper tape (for example, a double-width or triple-width paper tape). The paper tape slitting module 20 is located at the rear side of the unwinding module 10, and is used to slit the paper tape 200 into a plurality of small paper tapes. The rear side and the front side are both based on the transmission direction of the paper tape. When the paper tape 200 is fed into the paper tape slitting module 20, the paper tape slitting module 20 will cut the paper tape 200, thereby slitting the paper tape 200 into a plurality of small paper tapes along the width direction of the paper tape 200. When the paper tape slitting module 20 slits the paper tape 200 , the paper tape 200 may be divided equally or unequally along the width direction, depending on the width of the small paper tape required in the subsequent device.

[0027] The paper tape guiding and separating module 30 is located at the rear side of the paper tape slitting module 20, and is used to guide and separate the small paper tapes after slitting. That is, after the paper tape 200 is slid by the paper tape slitting module 20, it flows into the paper tape guiding and separating module 30, and the paper tape guiding and separating module 30 guides the small paper tapes after slitting, adjusts the distance between the small paper tapes, and allows the small paper tapes to be spaced a certain distance apart, thereby avoiding entanglement between them.

[0028] It is understandable that most of the paper tube forming machines in the prior art are single-channel paper tube production (only one paper tube can be produced at a time), with limited production efficiency, and cannot meet the synchronous production requirements of multiple paper tubes. To produce multiple paper tubes simultaneously, multiple paper tapes must be provided synchronously during feeding. If multiple paper rolls are unwound simultaneously to feed paper tapes, although the feeding requirements of multiple paper tapes can be met, the stability of multiple paper tapes is poor during long-distance transportation, and the synchronous forming effect is poor.

[0029] The paper tape slitting and conveying device 100 provided in the present embodiment is provided with the unwinding module 10, the paper tape slitting module 20 and the paper tape guiding and separating module 30. During production, the wider paper tape 200 can be installed and placed on the unwinding module 10, and then cut in width by the paper tape slitting module 20 to form a plurality of small paper tapes, and finally guided and conveyed by the paper tape guiding and separating module 30, so as to feed a plurality of paper tapes to subsequent equipment. The feeding stability is better, and the paper tapes are not easily entangled, thereby ensuring the synchronous forming effect of the subsequent paper tapes.

[0030] Preferably, in one embodiment, the paper tape slitting and conveying device 100 further includes a conveying module 40, which is located at the rear side of the paper tape slitting module 20 to drive the small paper tape to move. That is to say, in this embodiment, the small paper tape is pulled at the rear side by the conveying module 40, thereby providing power for the paper tape to move in the paper tape slitting module 20. The conveying module 40 includes a conveying drive mechanism 41, a driving wheel 42, a roller 43, and a roller drive mechanism 44, and the conveying drive mechanism 41 is connected to the driving wheel 42 to drive the driving wheel 42 to rotate. The wheel surface of the roller 43 is opposite to the wheel surface of the driving wheel 42, and the small paper tape passes between the wheel surface of the driving wheel 42 and the wheel surface of the roller 43. The roller drive mechanism 44 is connected to the roller 43 to drive the roller 43 to move relative to the driving wheel 42 to clamp or release the small paper tape. During production, the roller 43 and the driving wheel 42 clamp the paper tape, and the paper tape is conveyed by the roller structure, and the paper tape can be moved by the rotation of the driving wheel 42. The roller driving mechanism 44 drives the roller 43 to move, so that the roller 43 and the driving wheel 42 are separated, thereby loosening the paper tape and stopping the conveying.

[0031] Specifically, in one embodiment, the roller 43 is located above the driving wheel 42, and the roller driving mechanism 44 is a slide cylinder, which starts and stops the conveying of the roller structure by the extension and contraction of the slide cylinder. More specifically, the driving wheel 42 is made of stainless steel, and the roller 43 is a rubber roller, so as to realize low wear and high efficiency conveying of the paper tape.

[0032] Specifically, in one embodiment, the roller 43 is connected to the slide cylinder via a roller mounting seat 48 .

The conveying shaft 413 passes through the first bearing mounting sleeve 46, and the first bearing mounting sleeve 46 is provided with a first bearing 47 connected to the conveying shaft 413 at both ends. The first bearing mounting sleeve 46 at least partially extends into the conveying reducer fixing seat 45 and abuts against the conveying reducer fixing seat 45. The coaxiality is ensured by setting the matching requirements between the conveying reducer fixing seat 45 and the first bearing mounting sleeve 46. At the same time, the structure of the first bearing mounting sleeve 46 and the dual bearing mounting method also greatly improve the overall force and connection stiffness.

[0038] Specifically, in one embodiment, the conveying shaft 413 is connected to the shaft of the conveying reducer 412 through the first coupling 414. The coaxiality of the front and rear sections of the first coupling 414 can be ensured by setting the matching requirements between the conveying reducer fixing seat 45 and the first bearing mounting sleeve 46.

The slitting drive mechanism 21 is connected to the slitting shaft 22 to drive the slitting shaft 22 to rotate, and the blade 23 is arranged on the slitting shaft 22. That is to say, in this embodiment, the paper tape slitting module 20 uses the blade 23 to slitting the paper tape 200, and the slitting drive mechanism 21 drives the slitting shaft 22 to rotate, thereby synchronously driving the blade 23 to rotate. When the paper tape 200 flows through the blade 23, the blade 23 will cut the paper tape 200, thereby slitting the paper tape 200 into a plurality of small paper tapes.

[0042] Preferably, in one embodiment, along the axial direction of the slitting shaft 22, a plurality of (at least two) blades 23 are provided. The number of blades 23 provided is related to the small paper tapes to be formed by slitting. For example, in one embodiment, when the paper tape 200 needs to be slit into three small paper tapes, two blades 23 are provided, and the two blades 23 are spaced apart from each other, so that when the paper tape 200 flows through the blades 23, the two blades 23 slit the paper tape 200 into three small paper tapes. The paper tape slitting module 20 also includes a blade adjustment mechanism 24, which is connected to the blades 23 to adjust the distance between adjacent blades 23. By setting the blade adjustment mechanism 24, it is convenient to adjust the distance between the blades 23, and the slitting requirements of paper tapes of different widths can be quickly completed.

[0043] Preferably, in one embodiment, the paper tape slitting module 20 further includes a protective cover 25 and a blade stopper 26. The protective cover 25 covers the blade 23, and an avoidance groove 251 is provided on the protective cover 25, and the edge of the blade 23 extends out of the protective cover 25 through the avoidance groove 251. A portion of the blade stopper 26 is directly opposite to the portion of the blade 23 extending out of the protective cover 25, and the blade stopper 26 and the blade 23 are spaced apart from each other. With this structure, safety can be better guaranteed, and the blade 23 can also be better protected. The paper tape passes between the protective cover 25 and the blade stopper 26, and the stability of slitting is improved by separating the paper path from the related structures of the slitting shaft 22.

[0044] Specifically, in one embodiment, the protective cover 25 includes a cover body 252 and a protective member 253 disposed at the end of the cover body 252.

The second bearing mounting sleeve 28 at least partially extends into the motor fixing seat 27 and abuts against the motor fixing seat 27. By setting the matching requirements between the second bearing mounting sleeve 28 and the motor fixing seat 27, the coaxiality can be guaranteed.

[0047] Preferably, in one embodiment, the paper tape slitting module 20 further includes a stepped sleeve 201, and the blade 23 is mounted on the slitting shaft 22 through the stepped sleeve 201.

The movement of the blade 23 is opposite to the running direction of the paper path, which improves the stability and slitting effect of the slitting process. The coaxiality of the front and rear sections of the second coupling 202 can be guaranteed by setting the matching requirements of the second bearing mounting sleeve 28 and the motor fixing seat 27.

[0060] The paper tape slitting and conveying device 100 has high integration and can be used as an independent paper roll unwinding and slitting and conveying system. Adjustment margins are set between each module to meet the needs of paper tape slitting and conveying of different widths, and can be used in conjunction with a multi-track paper tube forming machine. The use of a single paper roll unwinding avoids the disadvantages of high requirements for the end surface of the paper roll unwinding and poor synchronization of the conveying process. The axial adjustment of the paper roll position is achieved through simple mechanical structures such as threads and clamps.

[0061] At the same time, in one embodiment, a paper tube forming unit is also provided, which includes the paper tape slitting and conveying device 100 and a paper tube forming machine. The paper tube forming machine is a multi-track paper tube forming machine (with multiple paper tube forming channels arranged inside, which can realize the synchronous forming of multiple paper tubes). The paper tape slitting and conveying device 100 is used to feed multiple paper tapes to the paper tube forming machine. The paper tape slitting and conveying device 100 uses a single paper roll to unwind and cut multiple sections and then transport and separate them to the paper tube forming machine. The paper tape slitting and conveying device 100 can stably convey small paper tapes to the paper tube forming machine, and can improve the paper supply efficiency, thereby ensuring the synchronous forming effect of multiple paper tubes in the paper tube forming machine.

[0062] The above description is only an implementation mode of the present invention. It should be pointed out that, for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present invention, but these all belong to the protection scope of the present invention.
