Description

TECHNICAL FIELD

[0001] The utility model relates to cigarette production packaging machine equipment technical field, especially in a kind of adjustable tow opening and stabilizing device. BACKGROUND

[0002] In the field of cigarette production, the quality of filter rod has a crucial influence on the quality of final product. ZL26E filter rod forming machine is the key equipment for producing fine gauge basic filter rod, wherein, YL16E tow opening machine is one of the core components of ZL26E filter rod forming machine.

[0003] In YL16E tow opening machine, acetate tow is separated and stretched by the power of airflow through first-stage air opening and second-stage air opening, and then is rolled and opened to realize longitudinal expansion. Further, after third-stage air opening, it reaches glycerol spraying chamber, where triacetin is uniformly sprayed, and then is conveyed into high-pressure spray gun to enter the next link. Finally, under the traction of cloth belt, the tow wrapped by forming paper coated with centerline glue and lap joint glue enters the inner and outer pressure plates to be rolled and formed, and is finally sent to drum for filter rod cutting.

[0004] In the process of first-stage air opening and second-stage air opening, the distance between them is relatively long (see Figure 1 ), and the tow is prone to irregular shaking during transmission, and the shaking intensifies when reaching the second-stage opening. Such shaking seriously interferes with the opening effect of the tow, resulting in that the opening and expansion of the tow cannot meet the expected requirements when it enters the glycerol tank.

[0005] Insufficient opening and expansion directly leads to serious quality problems in subsequent filter rod production. On the one hand, the suction resistance of filter rod becomes unstable, which greatly affects the consumer experience during the use of tobacco products and destroys the consistency and reliability of the product; on the other hand, the filter rod shrinkage phenomenon frequently occurs, which not only reduces the production qualification rate of filter rod and increases the production cost, but also has a negative impact on the stability and efficiency of the entire production process. INVENTION CONTENTS

[0007] To solve the above problems and achieve the above purpose, the utility model adopts the following technical scheme:

[0008] An adjustable stable device of opening of a bundle is installed on the second air opening machine (8) of YL16E bundle opening machine, it includes:

[0009] Support (1), the support (1) is detachably connected to the second air opening machine (8) by support locking assembly (11);

[0017] Shaft (53), the shaft (53) is in the shape of a cylinder, rotatable on the connecting plate (2) and locked and fixed by the limiting pin assembly locking piece (6).

[0018] The working principle of the utility model is:

[0019] 1. Stable bundle:

[0020] Under the guidance of limiting pin assembly (5) and the limitation of both sides, the bundle (9) is lightly placed on the shaft (53) of the two limiting pin assemblies (5) and passes through (when adjusting, the bundle (9) does not excessively compress the shaft (53), and the shaking amplitude is small, which is the index), thereby reducing the shaking of the bundle (9) and stably conveying to the second air opening machine (8).

[0021] 2. The width of the opening of the filament bundle is adjusted:

[0022] The limiting pin assembly (5) is composed of a first limiting pin (51) and a second limiting pin (52). The distance between the first limiting pin (51) and the second limiting pin (52) can be changed by adjusting the position of the second limiting pin (52) on the shaft (53), so that the width of the opening of the filament bundle (9) is adjusted to be within the range of the process quality standard, and the operator can adjust the opening ratio according to the opening state of the filament bundle (9).

[0023] 3. The angle of the device is adjusted:

[0024] When the tension of the filament bundle (9) is adjusted, the angle of the filament bundle (9) entering the secondary air opening machine (8) will also change, and the filament bundle (9) needs to be parallel to the device, so the angle of the device needs to be adjusted.

[0025] The angle of the device can be adjusted by the arc-shaped hole on the support (1) and the connecting plate locking assembly (4). When the connecting plate locking assembly (4) is loosened, the connecting plate (2) can rotate around the connecting plate positioning pin (3) in the range of the arc-shaped hole. When the appropriate angle is reached, the connecting plate locking assembly (4) is tightened.

[0026] After the angle of the device is changed, the angle of the first limiting pin (51) and the second limiting pin (52) with the filament bundle (9) also changes, so the angle of the limiting pin assembly (5) and the filament bundle (9) needs to be further adjusted to prevent the filament bundle (9) from being separated from the limiting of the first limiting pin (51) and the second limiting pin (52) due to the excessive angle.

[0027] After loosening the limiting pin assembly locking member (6), the two sets of limiting pin assemblies (5) are rotated to the appropriate angle, and then the limiting pin assembly locking member (6) is tightened.

[0029] 1. The present utility model significantly improves the stability of the filament bundle transmission and improves the product quality. Through the guidance of the limiting pin assembly and the limiting on both sides, the filament bundle can be lightly placed on the shaft of the limiting pin assembly during transmission, thereby greatly reducing the shaking of the filament bundle, avoiding the decline in opening effect caused by shaking, ensuring that the filament bundle reaches the expected width when entering the glycerol tank, making the resistance of the filter rod stable, and greatly reducing the shrinkage phenomenon, thereby improving the production qualified rate of the filter rod and improving the product quality.
