Description

Technical Field

[0001] The utility model relates to the technical field of tobacco processing equipment improvement, and is mainly aimed at the improvement of a KDF-5MF composite filter rod forming machine, and is specifically a paper edge guide device for preventing the edge of a forming paper from being stuck, and a composite filter rod forming machine equipped with the same. Background Art

[0002] The main function of the KDF-5MF composite filter rod forming machine is to produce fine filter rods, especially for the production of (Yunyan) fine Yunlong composite filter rods with a circumference of 16.85mm. This filter rod is composed of two base rods. During the production process, the two base rods are alternately spliced ​​into composite filter rod strips in the smoke gun channel. Under the traction of the cloth belt, the composite filter rod strips and the center line cold glue coated with forming paper enter the channel formed by the inner and outer pressure plates together, and the forming paper completely wraps the composite filter rod strips. Then, the forming paper is sent to the next filter rod cutting link for cutting.

[0003] However, due to the narrow width of the cloth belt and the shaping paper and the long length of the pipe passage in the KDF-5MF thin-line Yunlong compound machine, the shaping paper occasionally swings longitudinally in the pipe pressure plate. As a result, the position of the shaping paper may change and press under the entrance of the cigarette tongue, causing the edge of the composite filter rod to jam. When this happens, the quality of the shaping paper wrapping the filter rod will be poor.

[0004] The shaping paper moves in a uniform linear motion along with the cloth belt in the pipe passage. During the motion, the cloth belt or shaping paper may fluctuate slightly, which will cause the position of the shaping paper to change. If the shaping paper is pressed under the entrance of the cigarette tongue, the edge of the composite filter rod may be squeezed and transferred to the inner and outer pressure plate channels, resulting in quality problems such as the filter rod being loosely wrapped. In order to ensure the quality of the filter rod, special attention should be paid to the movement stability of the cloth belt and shaping paper during operation to avoid quality problems caused by changes in the position of the shaping paper. Summary of the invention

[0005] In order to solve the deficiencies and problems existing in the above-mentioned prior art, the inventor has improved the design and provided an accessory structure that can be used on the cigarette gun pressure plate on the composite filter rod forming machine, aiming to solve the problem that the shaping paper is pressed under the cigarette tongue due to fluctuations during the production process, which clamps one side of the paper edge, resulting in loose filter rod wrapping. A paper edge guide device is designed to prevent the shaping paper edge from being clamped. The device has the functions of stabilizing the shaping paper edge, reducing vibration, and preventing the shaping paper from being pressed at the entrance of the cigarette tongue. It effectively improves the filter rod wrapping quality and continuous production rate, reduces the defective rate and downtime maintenance rate, and ensures the processing and production efficiency of the equipment. Specifically, the utility model is implemented as follows:

[0006] The paper edge guide device for preventing the edge of the formed paper from being stuck includes: a guide blade, which is composed of an integrally formed horizontal plate and a vertical plate, and has a cross-section of " " is installed on the base; the base is installed on the cigarette gun pressing plate of the composite filter rod forming machine and is used to install a guide scraper on it; the lower edge of the vertical panel is attached to the inner wall of the cigarette gun channel and extends downward into the cigarette gun channel, but does not contact the forming paper.

[0007] Furthermore, the lower edge of the vertical panel is an inclined surface, which gradually approaches the inner wall of the smoke gun channel downward, and the scraper edge of the inclined surface is provided with a chamfer or a plane.

[0008] Furthermore, the width of the base is adapted to the width of the cigarette gun pressing plate on one side of the composite filter rod forming machine, so that after the base is installed on the cigarette gun pressing plate, the side of the base facing the cigarette gun channel is flush with the inner wall surface of the cigarette gun pressing plate.

[0009] Furthermore, a downwardly extending flange is provided on the bottom edge of the side of the base away from the cigarette gun passage, and the distance between the flange and the vertical panel is matched with the width of the cigarette gun pressing plate, so that the cigarette gun pressing plate is just placed therein.

[0010] Furthermore, the horizontal plates are provided with height adjustment screw holes and fastening screw holes, and the top surface of the base is provided with fixing screw holes at positions corresponding to the fastening screw holes, and the fastening bolts can be inserted into the fastening screw holes and the fixing screw holes to install the guide scraper on the base; after the height adjustment bolt passes through the height adjustment screw hole, the bolt end contacts the top surface of the base.

[0011] Furthermore, the fastening screw holes are waist-shaped screw holes in the transverse direction.

[0012] Furthermore, a magnetic attraction component is embedded and fixedly installed on the bottom surface of the base, so that the base can be fixed on the plate surface of the cigarette gun pressure plate by magnetic attraction.

[0014] Another aspect of the utility model provides a composite filter rod forming machine, wherein the above-mentioned paper edge guiding device is installed on the cigarette gun pressing plate of the cigarette gun channel.

[0015] Working principle of the utility model: the device is mainly composed of a guide scraper and a base. The base is used to provide installation and fixation on the cigarette gun pressure plate. The special shape structure of the guide scraper enables its vertical panel to extend downward into the cigarette gun channel, but does not contact the shaping paper. It is located in the upper area of ​​the shaping paper. The device is installed in the middle area where the shaping paper is prone to swing or shake. When the composite filter rod forming machine is in operation, causing the shaping paper to shake, the existence of the vertical panel can compress the longitudinal space of the shaping paper during shaking displacement, limit the displacement caused by the shaking, and thus reduce the displacement and offset probability of the shaping paper caused by shaking. With two sets of screw holes and bolts, the displacement adjustment of the guide scraper in both the horizontal and vertical directions can be realized, so as to achieve more accurate control and improve the use effect of the device in equipment operation.

[0016] Beneficial technical effects of the utility model:

The special shape and structure of the guide scraper allows the vertical panel to extend downward into the cigarette gun channel without contacting the shaping paper, limiting the displacement caused by the shaking of the shaping paper and reducing the probability of the shaping paper being stuck.

[0018] (2) The paper edge guide device is easy to adjust: The paper edge guide device has height adjustment screw holes and fastening screw holes, which can be used to adjust the horizontal and vertical displacements, thereby achieving precise control. In this way, the position of the guide blade can be adjusted according to specific needs to ensure the stability of the position of the forming paper, improve the anti-stuck effect of the forming paper edge, and improve the applicability and controllability of the device.

[0019] (3) Good stability of base fixation: The base is installed on the cigarette gun pressure plate and fixed by a magnetic suction piece. The magnetic suction piece uses a magnetic block, magnetic ring, magnetic strip or magnetic sheet to adsorb the base on the cigarette gun pressure plate. It is not a hard connection. On the one hand, the installation position is easy to adjust and has good flexibility. On the other hand, there is no need to improve or process the cigarette gun pressure plate.

[0020] (4) Improving the quality of filter rod molding: By using the paper edge guide device in this technical solution, the position and stability of the molding paper are effectively controlled, and the probability of displacement and offset of the molding paper due to shaking is reduced, thereby improving the molding quality of the filter rod.
