Description

Technical Field

[0001] The utility model relates to the technical field of filter rod production equipment, in particular to an automatic hole-opening device for filter rod production. Background Art

[0002] A filter rod refers to a cylindrical object with filter material as the main part, which is used to filter smoke and reduce the inhalation of harmful substances. Common ones include acetate fiber, polypropylene fiber, etc., which can absorb and filter harmful substances such as tar and nicotine in smoke. Filter rods play an important role in cigarettes. They can not only filter harmful substances, but also improve the taste and prevent tobacco from scattering. With the continuous advancement of science and technology, the performance and function of filter rods are also constantly improving. Punching cigarette filter rods is an important process in cigarette production. The purpose of punching cigarette filter rods is mainly to adjust the ventilation rate of cigarettes, dilute smoke, reduce the harm of smoking to the human body, and also improve the taste and aroma of cigarettes. Different punching methods have their own advantages and disadvantages. Tobacco companies will choose the appropriate punching method according to production needs and product quality requirements;

[0003] Patent application number 202311844571.9 discloses a filter rod circumferential perforation device. By directly perforating the filter rod after coating, the device effectively perforates the filter rod circumferentially during its rotation, ensuring stable connection of the perforations on the outside of the filter rod. The device also effectively controls the filter rod's suction resistance based on the number of perforations, effectively cooling high-temperature flue gas and improving the smoker's experience.

[0004] However, the above-mentioned filter rod circumferential punching device uses laser burning to punch holes, which is not convenient for accurately controlling the punching depth and easily causes excessive burning to affect the quality of the filter rod. When the above-mentioned filter rod circumferential punching device is used for punching, the filter rod needs to be manually placed between the first clamp and the second clamp for clamping. At the same time, after the punching is completed, the filter rod needs to be manually removed and replaced. If the filter rod is offset during clamping, it is easy to affect the punching effect. Therefore, the utility model proposes an automatic hole-opening device for filter rod production to solve the problems existing in the prior art. Utility Model Content
