Description

Technical Field

[0001] The utility model relates to the technical field of cigarette production equipment, and more specifically, to a cigarette tipping paper splicing mechanism. Background Art

[0002] The current cigarette production equipment has achieved fully automated production in all processes. In order not to affect the production continuity of the cigarette making machine, each unit must achieve 24-hour non-stop operation. The cigarette rolling and connecting machine unit is also equipped with a tipping machine to achieve automatic replacement of tipping paper without stopping the machine.

[0003] like Figure 1 As shown, the paper roll in use is supplying paper to the printing unit normally. The paper tape linear speed is consistent with the printing speed. After the old paper roll reaches a certain diameter, the paper splicing control mechanism sends a signal. The new paper roll is gradually accelerated by the upper paper guide roller, the lower paper guide roller and the acceleration roller until the paper speed is equal to that of the old paper roll. There is a tape between the new paper roll and the old paper roll. When the old paper roll reaches the specified diameter, the paper splicing control mechanism sends an automatic paper splicing signal. An upper knife holder is provided above the old paper roll holder, and a lower knife holder is provided below. The lower knife holder and the old paper roll holder are driven by the driver to move closer to the new paper roll. When the old paper roll is pressed against the new paper roll, the double-sided tape bonds the new paper roll to the old paper roll. At present, the lower knife holder cuts off the guide paper of the new paper roll, and the upper knife holder cuts off the old paper roll. The new paper roll enters the paper feeding gap driven by the old paper roll. Since the length of the double-sided tape is fixed, and in order to avoid collision between the lower knife holder and the acceleration roller, there is a distance between the blade of the lower knife holder and the double-sided tape, which determines that the convex shoulder left by the guide paper of the splicing joint formed after splicing (the convex shoulder refers to the part of the new paper roll head that does not stick to the double-sided tape after the guide paper is cut off) is longer, and the general length is more than 30mm. In the subsequent process of gluing and cutting the tipping paper, sticky paper heads will inevitably be cut out. The paper head can easily stick to the glued tipping paper during the rubbing process, resulting in unqualified cigarettes in appearance, affecting the quality of the cigarettes. Therefore, minimizing the distance of the convex shoulder is a technical problem to be solved by technical personnel in this field. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a cigarette tipping paper splicing mechanism, wherein the convex shoulder of the new tipping paper head reduces the influence of the generated broken paper heads on the cigarette quality.

[0037] The embodiments of the present invention are written in a progressive manner.

[0038] like Figure 2 As shown, a cigarette tipping paper splicing mechanism,

[0039] The rack 100 is included.

[0040] A conveying mechanism 200 mounted on the frame 100 for conveying a new tipping paper roll 500;

[0041] Install the rocker mechanism on the frame 100;

[0042] A tape holder 300 placed between the new tipping paper 500 and the old tipping paper 400 for placing the double-sided tape 310;

[0043] A pressure roller 800 installed on the rocker mechanism and facing the new assembling paper conveying passage at the side for pressing the old tipping paper 400 toward the new tipping paper 500;

[0044] An upper knife holder 600 mounted on the frame 100 for cutting the old tipping paper 400, and

[0045] A lower knife frame 700 mounted on the frame 100 for cutting the leading end of the new tipping paper 500,

[0046] The lower blade holder 700 is provided with a lower cutting blade 710 , the blade edge of the lower cutting blade 710 is tangent to the pressure roller 800 , and the angle between the lower cutting blade 710 and the horizontal plane is 80-85°.

[0047] like Figure 1As shown, a paper splicer for tipping paper in the prior art includes a frame 100, a conveying mechanism 200 mounted on the frame 100 for conveying a roll of new tipping paper 500; a rocker mechanism mounted on the frame 100; a tape holder 300 placed between the new tipping paper 500 and the old tipping paper 400 for placing a double-sided adhesive tape 310; a pressure roller 800 mounted on the rocker mechanism and facing the new tipping paper conveying channel on the side for pressing the old tipping paper 400 toward the new tipping paper 500; an upper knife holder 600 mounted on the frame 100 for cutting the old tipping paper 400, and a lower knife holder 700 mounted on the frame 100 for cutting the leading end of the new tipping paper 500. When the old tipping paper 400 reaches a certain diameter, a message is sent to the controller, and the controller starts the conveying mechanism 200. The front end guide paper of the new tipping paper 500 is installed on the conveying mechanism 200, driving the conveying of the new tipping paper 500. The conveying speed of the conveying mechanism 200 gradually increases. When the conveying speed of the new tipping paper 500 is equal to the conveying speed of the old tipping paper 400, the rocker mechanism is started to drive the pressure roller 800 to approach the conveying mechanism 200. At this time, the old tipping paper 400 is pressed against the new tipping paper 500, and the glue is pressed against the new tipping paper 500. The double-sided tape 310 is placed on the belt rack 300 in advance. When the old tipping paper 400 approaches the new tipping paper 500, the double-sided tape 310 adheres the old tipping paper 400 and the new tipping paper 500 together. At the same time, the upper paper cutter 610 on the upper knife rack 600 cuts the old tipping paper 400, and the lower cutting blade 710 of the lower knife rack 700 cuts the front guide paper of the new tipping paper 500. Under the bonding effect of the double-sided tape 310, the new tipping paper 500 is brought into the paper feeding path of the original old tipping paper, thereby realizing the paper splicing process of the new and old papers. Since the lower cutting blade 710 on the lower knife holder 700 is facing the conveying mechanism 200, in order to protect the lower cutting blade 710 and the conveying mechanism 200, in general, the blade of the lower cutting blade 710 is at least 30 mm away from the lower end of the double-sided tape 310. The cutting position of the lower cutting blade 710 and the position of the lower end of the double-sided tape 310 are recorded as a convex shoulder. The convex shoulder is used to collect paper scraps in the subsequent process of gluing and cutting the tipping paper. The paper scraps are easily attached to the glued tipping paper during the rubbing process, affecting the quality of the cigarette. In the utility model, the blade of the lower cutting blade 710 is tangent to the pressure roller 800, and the angle between the lower cutting blade 710 and the horizontal plane is 80-85°. The blade of the lower cutting blade 710 is closer to the lower end of the double-sided tape 310. After the paper splicing is completed, the convex shoulder of the front end of the new tipping paper 500 is greatly reduced. The utility model has a simple structure and can significantly reduce the length of the convex shoulder.

[0048] The lower blade holder 700 of the utility model comprises a rotating part 730 and a blade holder 720 mounted on the rotating part 730, wherein the rotating part 730 is rotatably mounted on the frame 100; the pressure roller 800 is provided with a rotating driving sheet 810, wherein the rotating driving sheet 810 abuts against the rotating part 730; and the lower cutting blade 710 is mounted on the blade holder 720. The rotating part 730 of the lower blade holder 700 is rotatably mounted on the frame 100 and can rotate, so that the blade holder 720 and the lower cutting blade 710 can be moved toward the new tipping paper 500 to cut off the front guide paper of the new tipping paper 500. The rotating part 730 can be provided with a driving device alone, or the lower blade holder 700 can be driven by a rocker mechanism through a driving block to rotate, and the manner in which the lower cutting blade 710 can be moved toward the new tipping paper 500 is within the protection scope of the utility model.

[0049] The blade support 720 of the utility model includes a blade support portion 721, and the lower cutting blade 710 is installed on the blade support portion 721. The blade support portion 721 can provide better support for the lower cutting blade 710, and also realize more possibilities for the angle of the lower cutting blade 710. The lower cutting blade 710 is installed on the blade support portion 721, which is also convenient for installation, disassembly and maintenance.

[0050] The end of the blade support portion 721 of the utility model is provided with a chamfered surface 723 adapted to the pressure roller 800. The end chamfer of the blade support portion 721 is adapted to the pressure roller 800, so that the reverse side of the chamfer of the blade support portion 721 can be closer to the pressure roller 800. The lower cutting blade 710 is installed on the mounting surface closer to the pressure roller 800. The blade edge of the lower cutting blade 710 can be close to the lower end of the double-sided tape 310, thereby reducing the length of the boss.

[0051] The lower cutting blade 710 of the utility model is installed on the back of the chamfered surface 723 of the blade support part 721, and the blade bevel of the lower cutting blade 710 is opposite to the new tipping paper 500. Since the end of the blade support part 721 is provided with a chamfered surface 723 adapted to the pressure roller 800, the lower cutting blade 710 is installed on the back of the chamfered surface 723 of the blade support part 721, which can further reduce the distance from the lower blade blade to the lower end of the double-sided tape 310.

[0052] like Figure 3As shown, the blade support 720 of the utility model also includes a base 722, and the base 722 forms an acute angle with the blade support part 721. The blade support also includes a base 722, and the base 722 forms an acute angle with the blade support part 721. Such a structure is installed on the rotating part 730, which is more stable than the blade support part 721 directly installed on the rotating part 730. The blade support part 721 and the base 722 can be made in one piece, or they can be connected by welding or the like.

[0053] The base 722 of the present invention is mounted on the rotating part 730 by screws. The screw mounting method is simple and fast, and is easy to replace and repair.

[0054] The conveying mechanism 200 of the utility model comprises an upper paper guide roller 210, an accelerating roller 220 and a lower paper guide roller 230. The new tipping paper 500 is sequentially conveyed on the upper paper guide roller 210, the accelerating roller 220 and the lower paper guide roller 230. The side of the accelerating roller 220 is directly opposite to the side of the pressure roller 800. The conveying mechanism 200 is used to convey the new tipping paper 500, and the speed of the new tipping paper 500 roll and the old tipping paper 400 are equalized by slowly accelerating.

[0055] The blade of the lower cutting blade 710 of the utility model is no more than 4 cm away from the lower end of the double-sided tape 310, so that the convex shoulder of the new tipping paper 500 is less than 4 cm in width, which greatly reduces the paper shredding in the subsequent process and reduces the impact of the paper shredding on the quality of cigarettes.

[0056] The upper knife holder 600 of the utility model is provided with an upper paper cutter 610 opposite to the old tipping paper 400, and the upper end of the rotating drive sheet 810 is provided with a paper cutter fixed knife 620 opposite to the upper paper cutter 610. The paper cutter fixed knife 620 is on the rotating drive sheet 810 and rotates together with the rotating drive sheet 810. When the pressure roller 800 approaches the conveying mechanism 200, the paper cutter fixed knife 620 moves toward the direction of the old tipping paper 400 and abuts against the upper paper cutter 610, so that the upper paper cutter 610 has a higher success rate in cutting the old tipping paper 400.

[0057] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
