Description

A splicing paper cutting device for cutting at the glue spray interruption line Technical Field

[0001] This utility model relates to the field of splicing technology, and more specifically, to a splicing paper cutting device that cuts at the glue spray interruption line, which can reduce equipment and quality risks caused by glue sticking to the cutting blade. Background Technology

[0002] In cigarette production, the cutting and adhesive application of tipping paper are crucial steps. Tipping paper requires adhesive to be sprayed onto specific locations by an adhesive spraying mechanism, then cut to the appropriate length by a cutting device before being attached to the cigarette body. However, in existing technology, when the adhesive spraying process is interrupted (e.g., a temporary stop in adhesive supply, malfunction of the adhesive spraying component), the tipping paper cutting often cannot accurately correspond to the interruption point. This results in the cut tipping paper potentially including un-adhesive portions or incorrect cutting within the adhesive spraying area. This not only wastes tipping paper material but can also affect cigarette quality, such as causing problems like weak tipping paper adhesion. The PROTOS series of cigarette machines, currently among the world's most advanced cigarette machines, uniquely employs adhesive spraying technology for its tipping paper.

[0003] Therefore, it is necessary to propose a splicing paper cutting device that cuts at the glue spray interruption line to address the above-mentioned technical problems. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the purpose of this utility model is to provide a splice paper cutting device that cuts at the glue spray interruption line, so as to solve the problem of inaccurate splice paper cutting when glue spraying is interrupted as mentioned in the background art.

[0005] A splicing paper cutting device that cuts at the glue spray interruption line includes a glue spraying mechanism, a paper guiding mechanism, a path length fine-tuning mechanism, a paper cutting wheel, a roller, a cigarette rolling mechanism, and a frame. The glue spraying mechanism, paper guiding mechanism, path length fine-tuning mechanism, paper cutting wheel, roller, and cigarette rolling mechanism are all mounted on the frame. The splicing paper passes through the glue spraying mechanism, paper guiding mechanism, path length fine-tuning mechanism, paper cutting wheel, roller, and cigarette rolling mechanism in sequence.

[0006] Preferably, the glue spraying mechanism includes a glue inlet flange, a rotor, a nozzle head, a distributor, a scraper, and a glue spraying transmission mechanism. The glue inlet flange is installed at the output end of the glue spraying transmission mechanism through the nozzle head. The rotor is disposed inside the nozzle head. The distributor is installed on the side of the nozzle head. The scraper is installed on the distributor.

[0007] Preferably, the circumference of the rotor is provided with a plurality of baffles.

[0008] Preferably, the nozzle head is provided with a plurality of nozzle head dispensing ports, and the distributor is provided with a plurality of distributor dispensing ports corresponding to the nozzle head dispensing ports.

[0009] Preferably, the path length fine-tuning mechanism includes a paper guide roller, a paper guide roller shaft, an eccentric adjustment block, a locking screw, and a mounting base. The eccentric adjustment block is mounted on the mounting base by the locking screw, and the paper guide roller is mounted on the eccentric adjustment block by the paper guide roller shaft.

[0010] Preferably, the glue spraying transmission mechanism includes a first drive motor, a second drive motor, a gear, a transmission outer cylinder, and a transmission inner cylinder. The output end of the first drive motor is connected to the gear. The outer cylinder has ring teeth on its circumference. The gear meshes with the ring teeth through a toothed belt. The second drive motor is installed at the center of one end of the outer cylinder. The output end of the second drive motor is fixed to one end of the inner cylinder. The inner cylinder is disposed inside the outer cylinder.

[0011] Preferably, a connecting ring is connected to the other end of the outer transmission cylinder, the connecting ring is connected to the nozzle head, and a connecting shaft is connected to the other end of the inner transmission cylinder, the connecting shaft is connected to the rotor, and the connecting ring is fitted onto the outside of the connecting shaft.

[0013] Compared with existing technologies, it has the following advantages:

[0014] 1. This utility model can achieve paper cutting at the glue-free position of the interruption line each time it is loaded, reducing the phenomenon of glue sticking to the blade, reducing the quality defects of glue residue mixed in cigarettes, and reducing the difficulty of cleaning and maintaining the roller and paper cutting wheel for the machine operator.

[0015] The rotor is installed in the inner cavity of the outer rotating body. The annular baffle protruding on the circumference of the rotor divides the rotor into three glue zones. The small baffle controls the opening and closing of the glue spraying channel, so as to block the glue channel when the machine stops and prevent glue from flowing out.

[0016] 3. When the machine is working, the motor drives the nozzle head to the working position, and another motor drives the rotor inside the nozzle head to rotate. Each rotation of the rotor generates six glue application marks, achieving the amount of glue sprayed onto the tipping paper in accordance with the process requirements.

[0031] Furthermore, the glue spraying mechanism 1 includes a glue inlet flange 101, a rotor 102, a nozzle head 103, a distributor 104, a scraper 105, and a glue spraying transmission mechanism 106.

The distributor 104 is installed on the side of the nozzle head 103, and the scraper 105 is installed on the distributor 104.

[0032] Furthermore, the circumferential portion of the rotor 102 is provided with a plurality of baffles 107.

[0033] Furthermore, the nozzle head 103 is provided with a plurality of nozzle head glue outlets 108, the distributor 104 is provided with a plurality of distributor glue outlets 109 corresponding to the nozzle head glue outlets 108, and the nozzle head 101 has eight glue channels.

[0034] Furthermore, the path length fine-tuning mechanism 3 includes a paper guide roller 301, a paper guide roller shaft 302, an eccentric adjustment block 303, a locking screw 304, and a mounting base 305.

[0035] Furthermore, the glue spraying transmission mechanism 106 includes a first drive motor 1061, a second drive motor 1062, a gear 1063, a transmission outer cylinder 1064, and a transmission inner cylinder 1065.

[0037] Furthermore, a sealing ring 10610 is provided on the circumference of the connecting ring 1068, and a sealing ring groove 1031 is provided in the nozzle head 103 to cooperate with and connect with the sealing ring 10610.

[0038] Compared with existing technologies,

[0039] 1. This utility model can achieve that each paper 8 is cut at the glue-free position of the interruption line, reducing the phenomenon of glue sticking to the blade, reducing the quality defects of cigarettes mixed with glue residue, and reducing the difficulty of cleaning and maintaining the roller 5 and paper cutting wheel 4 for the machine operator.

[0040] The rotor 102 is installed in the inner cavity of the outer rotating body. The annular baffle 107 protruding on the circumference of the rotor 102 divides the rotor 102 into three glue zones. The small baffle 107 controls the opening and closing of the glue spraying channel, so as to block the glue channel when the machine stops and prevent glue from flowing out.

[0041] 3. When the machine is working, the motor (first drive motor 1061 or second drive motor 1062) drives the nozzle head 103 to the working position, and another motor drives the rotor 102 inside the nozzle head 103 to rotate. Each rotation of the rotor 102 generates six glue application marks, achieving the amount of glue sprayed onto the tipping paper (tipping paper 8) in accordance with the process requirements. As the rotor 102 rotates in the nozzle head 103, the baffle 107 periodically closes the glue channel leading to the dispenser 104, forming an interruption line with a width of 0.8mm. The interruption line is almost glue-free.

[0042] This invention, by incorporating a path length fine-tuning mechanism 3, can promptly adjust the conveying path length of the tipping paper 8 when glue spraying is interrupted. This ensures that the cutting wheel 4 and the roller 5 can accurately cut at the point of glue spraying interruption, avoiding inaccurate cutting of the tipping paper 8 due to glue spraying interruption, reducing material waste, and improving the quality of cigarette production. Simultaneously, the special structural design of the glue spraying mechanism 1, such as the baffle 107 on the rotor 102 and multiple glue outlets (nozzle head glue outlet 108, distributor glue outlet 109), ensures the uniformity and stability of glue spraying, further improving the glue spraying quality of the tipping paper 8 and providing a reliable guarantee for subsequent cigarette production processes.

[0043] Figure 10 shows a schematic diagram where the interruption line of the splicing paper 8 coincides with the cutting position. A is the interruption line and B is the cutting position.

[0044] By utilizing the glue spray interruption line, the path length fine-tuning mechanism 3 changes the path length from the glue application point to the cutting point of the roller 5 for the paper 8 to be dispensed, thereby changing the phase between the interruption line and the cutting position. This ensures that the paper 8 is cut at the glue-free position of the interruption line each time, reducing the phenomenon of glue sticking to the blade, reducing the quality defects of glue residue mixed in cigarettes, and reducing the difficulty of cleaning and maintaining the roller 5 and the paper cutting wheel 4 for the machine operator.

[0045] Technical solution adopted:

[0046] A path length fine-tuning mechanism 3 is installed at the position before the splicing paper 8 enters the shearing stage after gluing. The fine-tuning device can cause a path length change of 14mm to meet the adjustment range before and after the break line of the 27mm wide cork paper (splicing paper 8). The guide roller 301 of the fine-tuning device contacts the non-glued surface of the splicing paper 8. When the guide roller 301 moves upward, the path becomes longer, and vice versa.

[0047] Working principle:

[0048] The receiving paper 8 enters from one end of the frame 7 and first passes through the glue spraying mechanism 1. The glue spraying mechanism 1 introduces glue through the glue inlet flange 101. Driven by the glue spraying transmission mechanism 106 (including the first drive motor 1061, the second drive motor 1062, the gear 1063, the transmission outer cylinder 1064, the transmission inner cylinder 1065, the ring gear 1066, the toothed belt 1067, the connecting ring 1068, the connecting shaft 1069, etc.), the rotor 102 rotates, cooperating with the distributor 104 and the scraper 105 to evenly spray the glue onto the receiving paper 8. Then the receiving paper 8 passes through the paper guiding mechanism 2 (including the paper guide roller 301, the paper guide roller shaft 302, the eccentric adjustment block 303, the locking screw 304, the mounting base 305, etc.) for guidance and stable conveying. Next, the path length fine-tuning mechanism 3 adjusts the position of the guide roller 301 by adjusting the eccentric adjustment block 303 according to the glue spraying situation, thus fine-tuning the conveying path length of the tipping paper 8. When glue spraying is interrupted, the control system sends a signal, and the path length fine-tuning mechanism 3 quickly adjusts to make the conveying speed and position of the tipping paper 8 adapt to the cutting requirements. The cutting roller 4 and the cutter 5 cut the tipping paper 8 at the accurate position, and the cut tipping paper 8 enters the cigarette mechanism 6 and connects with the cigarette body.

[0049] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
