[0002] In the production process of cigarette filter rods, gelling is an important part of the development of new filter rod products. Gelling can provide additional flavor effects, improve the taste of smoking, and help increase the absorption of harmful substances. However, existing gelling equipment often needs to be matched with a specific filter rod forming machine, and most of the equipment is fixed and needs to be tightly integrated with the filter rod forming machine, which usually means large-scale technical transformation of the existing filter rod forming machine. Such transformation is not only costly, but may also lead to increased downtime of the forming machine, affecting production efficiency. In addition, fixed application devices are usually not flexible to adapt to different models of filter rod forming machines, nor are they easy to adjust to accommodate conventional filter rods of different specifications and models. These limitations restrict the flexibility and adaptability of production, and increase the production costs and operational risks of enterprises.

[0003] After searching, it was found that there are also structures related to gelling device in existing patent documents, such as a gelling device for filter rods in a forming machine with publication number CN109924541A, which includes a pre-dissolved glue storage barrel I, the glue outlets of pre-dissolved glue storage barrel I and pre-dissolved glue storage barrel II are respectively connected to the glue inlet of the glue storage barrel through a glue inlet pipe, and the two glue inlet pipes are respectively provided with a pneumatic valve I and a pneumatic valve II, and the glue outlet of the glue storage barrel is connected to the guide tongue gel filling device through a glue liquid delivery pipe, and the glue liquid delivery pipe is provided with a pneumatic valve III and a universal joint for fixing the glue liquid delivery pipe.

It is necessary to repeatedly adjust the tightness of the locking bolts and screws to adjust the relative position. At the same time, the adjustment accuracy of the position is affected by the operator's technical level, resulting in inaccurate gluing position and affecting product quality. Utility Model Content

DETAILED DESCRIPTION

[0033] To make the present invention more clearly understood, a cigarette filter rod fat coagulation applying device of the present invention is further described below with reference to the accompanying drawings. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] like Figure 1 、 Figure 2The device for applying gelled fat to cigarette filter rods is shown in FIG. It comprises a barrel 100 with a lid 110. The barrel 100 serves as a container for storing and stirring gelled fat, and is designed to be food-grade. A stirring device 120 is provided within the barrel 100, along with a temperature-controlled heating device 130 to ensure the gelled fat in the barrel 100 is kept at an appropriate temperature, facilitating thorough mixing and delivery of the gelled fat and additives. A delivery pipe 140 and a drain outlet 190 with a control valve are connected to the underside of the barrel 100. A pump 150 is provided on the delivery pipe 140 for pumping the gelled fat from the barrel 100. The output end of the delivery pipe 140 is connected to a gelled fat application head 160, which connects to the gelled fat port of a filter rod forming machine to deliver the gelled fat to the filter rods being processed. Furthermore, a heating jacket 170 is provided over the delivery pipe 140, and a heater 180 is provided on the gelled fat application head 160. The gelled fat applying head 160 is connected to the position adjusting device 200, and the gelled fat applying position and direction of the gelled fat applying head 160 can be adjusted by the position adjusting device 200, so as to facilitate matching with different filter rod forming machines.

[0035] The stirring device 120, the temperature control and heating device 130, the pump body 150, the heating sleeve 170 and the heater 180 are all controlled by the control module 400. Here, the pump body 150 is preferably a gear pump with high pumping accuracy; the control module 400 is a PLC control system, which can accurately control various parameters such as temperature and flow rate during the application of the gel according to the process speed of the filter rod forming machine. The structure of the PLC control system is a conventional technology in this field and will not be described here.

[0036] Combine Figure 1 As shown, the position adjustment device 200 includes a magnetic base 201. The magnetic base 201 serves as the support structure of the position adjustment device 200 and has a large support surface and a bottom plane for magnetic attraction of iron materials. The magnetic base 201 has a manual magnetic switch, and the magnetic on and off of the magnetic base 201 can be controlled by the magnetic switch. A first bracket 210 is provided on the magnetic base 201. The end of the first bracket 210 is connected to the second bracket 220 through a joint structure 300. The end of the second bracket 220 is connected to the third bracket 230 through another joint structure 300. The joint structures 300 at both locations are of the same structure. The gel applicator head 160 is provided on the third bracket 230; at least one of the first to third brackets is a telescopic bracket. In this example, the third bracket 230 is a telescopic bracket, and its structure is like the telescopic rod structure on an umbrella. By fixing it at any set position in the telescopic stroke, the support and telescopic functions are achieved.

[0037] Combine Figure 3As shown, the joint structure 300 includes a plate-shaped fixed base 301, on which a pair of vertically arranged first rotating shafts 302 are fixed. The pair of first rotating shafts 302 are rotatably connected to a first gear 303 and a first adjusting gear 304 that is externally meshed with the first gear 303 through bearings, so that the first gear 303 and the first adjusting gear 304 can rotate in a horizontal plane. An L-shaped support frame 305 is fixedly connected to the upper end surface of the first gear 303. It should be noted that the support frame 305 should avoid the first rotating shaft 302 to prevent interference between the two movements. The support frame 305 A pair of transversely arranged second rotating shafts 306 are connected to the outer side of the vertical plate. The axial directions of the first and second rotating shafts are perpendicular to each other. A second gear 307 and a second adjustment gear 308, which meshes externally with the second gear 307, are respectively connected to the pair of second rotating shafts 306. The second gear 307 and the second adjustment gear 308 can rotate within a vertical plane. The second rotating shaft 306 connected to the second gear 307 is connected to the vertical plate of the support frame 305 via a bearing. Another second rotating shaft 306 is fixedly connected to the vertical plate of the support frame 305 and connected to the second adjustment gear 308 via a bearing. A mounting seat 309 is provided on the second rotating shaft 306 fixedly connected to the corresponding second gear 307. In this embodiment, the mounting seat 309 is located on the inner side of the support frame 305 and is integrally connected to the second rotating shaft 306. Here, the mounting seat 309 and the fixed seat 301 serve as the two mounting locations for connecting the joint structure 300 to external components. The above-mentioned rotational connection method between the first gear 303 and the first adjusting gear 304 and the fixed base 301, as well as the rotational connection method between the second gear 307 and the second adjusting gear 308 and the support frame 305 are only used as schematic illustrations, as a conventional rotational connection structure to enable the above-mentioned gears to be rotatably set relative to the fixed base 301 and the support frame 305, and are not limited to the above-mentioned schematic structures.

[0038] Recombination Figure 3 、 Figure 4As shown, the first and second adjustment gears are each provided with a locking mechanism 310 to achieve the positioning and locking functions of the joint structure 300. Specifically, the locking mechanism 310 is used to lock the first and second adjustment gears and includes a rotatable eccentric locking wheel 311. The eccentric locking wheel 311 is connected to a handle 313 via a connecting shaft 312. The connecting shaft 312 is rotatably connected to a fixed support structure. The eccentric locking wheel 311 and the handle 313 are respectively located at opposite ends of the connecting shaft 312. The circumferential surface of the eccentric locking wheel 311 has a curved surface profile that changes linearly with respect to its rotation center. When the eccentric locking wheel 311 rotates, its curved surface profile forms a separation state and a pressing contact state with the end surfaces of the first and second adjustment gears, thereby forming an unlocking and locking effect respectively. Here, the fixed support structure can be arranged at the upper end positions of the first and second rotating shafts corresponding to the first and second adjusting gears. Considering the machinability, the two sides of the upper end portions of the first and second rotating shafts are milled into two planes; the selection of the position of the fixed support structure can make the overall structure of the joint structure 300 more compact and smaller in size while realizing the support of the locking mechanism 310 and the rotational connection of the eccentric locking wheel 311.

[0039] In addition, in order to facilitate the observation of the rotational displacement in the joint structure 300, the joint structure 300 is also provided with a scale 330 for marking the number of rotating teeth of the first and second adjustment gears. The scale 330 can be an arc-shaped scale corresponding to the outer peripheral contour of the first and second adjustment gears, and is located on the fixed support surface on their circumferential side. A certain tooth on the first and second adjustment gears is marked to act as a pointer.

[0040] Furthermore, the joint structure 300 further includes a fine adjustment mechanism 320 for respectively adjusting the first and second adjustment gears to rotate slightly. Figures 4 to 6As shown, the fine-tuning mechanism 320 includes a fine-tuning seat 321, which is located on one side of the first and second adjusting gears in the circumferential direction. A slide groove 322 is provided in the fine-tuning seat 321. The slide groove 322 is rectangular, and its length direction is parallel to the tangential direction of the circumferential edges of the first and second adjusting gears. The opening of the slide groove 322 faces the first and second adjusting gears, and a movable seat 323 is slidably connected in the slide groove 322. The movable seat 323 can slide along the length direction of the slide groove 322. The two can achieve an anti-rotation effect through a non-rotating cross-sectional shape, such as a rectangle, trapezoid, etc. The movable seat 323 is hinged with a rack 324 that meshes with the first and second adjustment gears. The hinged arrangement of the rack 324 allows it to engage or disengage with the first and second adjustment gears as it swings to different positions. Adjustment screws 325 are threaded onto either side of the fine-tuning seat 321 along the length of the slot 322. Rotating the adjustment screws 325 changes the relative position of the movable seat 323. This structural arrangement prevents interference between the coarse and fine adjustments of the joint structure 300. Preferably, the threads of the adjustment screws 325 are fine-pitch threads to improve the accuracy of the movement adjustment.

[0041] Of course, in order to facilitate the swinging operation of the rack 324, a joystick 326 is connected to the back of the rack 324. The joystick 326 is bent and extends out of the outside of the fine-tuning seat 321 for easy grasping. Correspondingly, an opening 327 is provided on the fine-tuning seat 321 to avoid the movement path of the handle.

[0042] Combine Figure 7 As shown, the barrel body 100 includes an inner liner layer 101, an insulation layer 102 and a protective layer 103 arranged in sequence from the inside to the outside; the inner liner layer 101 and the protective layer 103 are both made of food-grade stainless steel 304, and the insulation layer 102 is filled with polyurethane material; the heating element of the temperature control heating device 130 is located between the inner liner layer 101 and the insulation layer 102.

[0043] Combine Figure 8 As shown, the stirring device 120 includes a stirring shaft 121 located at one end in the barrel 100. The stirring shaft 121 is vertically arranged, and its other end extends outside the barrel 100 and is connected to the driving device 122. The driving device 122 is fixedly connected to the cover 110 of the barrel 100 via a mounting flange. Preferably, the driving device 122 is a pneumatic motor; the stirring shaft 121 is a double-blade spiral stirring shaft, which can improve stirring efficiency.

[0044] During operation, the device is controlled by control module 400 to stir, precisely pump, heat, and insulate the gel, and precisely add it to the filter rods to be formed in the filter rod forming machine. The position adjustment device 200 utilizes a joint structure to enable the first to third brackets to be adjusted at multiple angles and over a wide range. Specifically, the joint structure, through the action of two externally meshing gears and a combined locking mechanism, allows for coarse adjustment by manually gripping and moving (swinging) the first to third brackets. Simultaneously, each intermeshing tooth serves as the smallest moving unit, improving movement accuracy. While ensuring accurate position adjustment, operation is relatively simple, enabling rapid adjustment and precise determination of the gluing position. This overall improves the accuracy and stability of gluing the gel in the filter rods, thereby enhancing product quality.

[0045] The above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention may be implemented. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising from the essence of the present invention remain within the scope of protection of the present invention.
