Description

Technical Field

[0001] This utility model relates to the technical field of cigarette manufacturing, and in particular to a separation mechanism and conveying device suitable for three-section tipping paper. Background Technology

[0002] The existing tipping paper production process for cigarette equipment is as follows: The tipping paper is taken out of the paper tray, and after processes such as tension compensation, curling, and gluing, it enters the tipping paper adjusting device, and then enters the paper cutting wheel to be cut into sheet-shaped tipping paper according to the composite process requirements. Before entering the tipping paper curling process, the tipping paper is cut into three sections: inner, middle, and outer.

[0003] If the three sections of the tipping paper (inner, middle, and outer) do not have sufficient gaps before entering subsequent steps, misalignment of the tipping paper may lead to cigarette quality problems during subsequent processing. Therefore, the three sections of tipping paper need to be separated before entering the tipping paper readjustment device to ensure that the tipping paper production process meets the requirements of cigarette manufacturing.

[0004] Utility model patent CN219522270U discloses a tipping paper cutting device for a cigarette machine, including a fixed plate. The fixed plate is equipped with a cutting mechanism for cutting the tipping paper and a limiting mechanism for separating the cut tipping paper. The cutting mechanism includes a cutter base with two cutters mounted on it. The two cutters are parallel and oriented in the same direction as the tipping paper's conveying direction, cutting the tipping paper into three parallel tipping paper segments. The limiting mechanism includes three limiting seats arranged side-by-side, each with a limiting groove. The three limiting grooves are staggered sequentially, and the openings of the three limiting grooves correspond to the three cut tipping paper segments.

[0005] The aforementioned device uses a limiting mechanism to limit the feeding of the paper, thereby ensuring the separation of the three-section paper. However, the design of the limiting mechanism with three limiting seats and limiting grooves on each of the three limiting seats is relatively complex and costly. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] This utility model provides a separation mechanism suitable for three-section splicing paper 9, the specific structure of which is as follows:

[0028] A separation mechanism suitable for three-section splicing paper 9, see [reference] Figure 1 and Figure 2 The mechanism includes a main body 1, on which a conveying trough 2 is provided. The guiding direction of the conveying trough 2 is the same as the length direction of the three-section splice paper 9, and at least two limiting parts 3 for separating the three-section splice paper 9 are provided inside it. The limiting parts 3 are spaced apart along the width direction of the three-section splice paper 9. In use, the limiting parts 3 can be used to separate the three-section splice paper 9, avoiding misalignment problems caused by incomplete separation of the splice paper in subsequent processing or handling operations. The mechanism has a simple structure and low construction cost.

[0029] In some embodiments, the limiting part 3 is preferably provided with an inclined surface 6 for guiding the three-section splicing paper 9. The inclined surface 6 can improve the guiding accuracy of the limiting part 3 for the splicing paper and better guide the splicing paper to the correct position. In addition, the setting of the inclined surface 6 can reduce the surface contact between the limiting part 3 and the splicing paper during conveying, which is beneficial to reduce the magnitude of friction.

[0030] In some embodiments, the main body 1 of the mechanism is movable along the width direction of the three-section splicing paper 9, and the position of the separation mechanism can be adjusted according to the working conditions.

[0031] In some embodiments, to accommodate different splice paper separation requirements, the limiting part 3 is movable along the width direction of the three-segment splice paper 9. Specifically, as Figure 2 As shown, the bottom of the conveying trough 2 is provided with several first oblong holes 7, and the limiting part 3 is provided with first threaded holes corresponding to the first oblong holes 7. The limiting part 3 and the conveying trough 2 are connected by bolts passing through the first oblong holes 7 and the first threaded holes. In use, by moving the bolts to their positions in the first oblong holes 7, the limiting part 3 is adjusted in the width direction.

[0032] In some embodiments, the conveying trough 2 is provided with a low-friction layer to reduce friction, which can reduce the damage to the three-section splicing paper 9 caused by friction with the limiting part 3 during conveying. Specifically, the low-friction layer may be coated with a lubricating material, such as polytetrafluoroethylene.

[0033] This utility model also provides a conveying device suitable for three-section splicing paper 9, such as Figure 1 As shown, the conveying device includes a roller shaft 4 that drives the three-section splicing paper 9 to convey the paper by rotation, and the separation mechanism described above that is suitable for the three-section splicing paper 9.

[0034] In some embodiments, to ensure that the disassembly and assembly of the separating mechanism does not affect other components of the conveying device, the main body 1 of the mechanism has a columnar structure and is connected to the roller shaft 4; the limiting part 3 has an annular structure, and its center is located on the axis of the main body 1. As a further improvement of this embodiment, a mounting hole is provided in the middle of the main body 1, and the opening direction of the mounting hole extends along the axial direction of the main body 1; the main body 1 is sleeved on the outside of the roller shaft 4 through the mounting hole. To facilitate disassembly and assembly and maintenance, the main body 1 and the roller shaft 4 are preferably detachably connected by a pin structure 5.

[0035] In some specific embodiments, in order to achieve the adjustability of the main body 1 in the width direction of the three-section splicing paper 9, the preferred hole pin structure 5 includes at least one second waist-shaped hole 8 provided on the main body 1, a second threaded hole provided on the roller shaft 4 opposite to it, and a positioning pin passing through the second waist-shaped hole 8 and the second threaded hole. In use, by adjusting the position of the positioning pin in the second waist-shaped hole 8, the movement of the main body 1 in the width direction of the three-section splicing paper 9 can be adjusted.

[0036] In some specific embodiments, the separation process of the separation mechanism for the three-section splice paper 9 is as follows: First, according to the feeding requirements of the splice paper, the positions of the bolts in the first oblong hole 7 and the second oblong hole 8 are adjusted respectively to determine the spacing of the limiting part 3 and the position of the mechanism body 1. Then, the three-section splice paper 9 is separated from top to bottom (within...). Figure 2 (Taking the direction shown as an example) When it enters the conveying groove 2, due to the presence of the limiting part 3, the three sections that were originally tightly attached are separated into appropriate positions and can continue to enter the next mechanism.

[0037] The above-described contents can be implemented individually or in combination in various ways, and all such variations are within the protection scope of this utility model.
