Description

Technical Field

[0001] The present invention relates to a gluing system, in particular to a cigarette tipping paper gluing system which forms a predetermined glue pattern on cigarette tipping paper by spraying through a nozzle after the glue is transported under fully enclosed conditions, and cleans and seals the gluing nozzle in time during the gluing operation stop process to ensure efficient and reliable operation of the gluing process, and belongs to the technical field of tobacco processing. Background Art

[0002] In the production process of filter cigarettes, it is necessary to use glue-coated tipping paper sheets to wrap the filter and the cigarette rod to form a long cigarette. Therefore, the gluing of the tipping paper is a very important process in the filter cigarette assembly process, and the gluing quality has an important impact on the quality of the final cigarette product. For example, poor gluing of the tipping paper can easily lead to quality defects in cigarette dilution, glue leakage pollution, affect the rubbing, easily cause cigarette leakage, tipping paper warping, wrinkles, ventilation rate not meeting the standard and other product defects. Once a gluing defect occurs, the cigarette machine will remove these tipping paper sheets with gluing defects and the matching cigarette rods and filters, resulting in a large amount of material waste. The gluing process of the tipping paper is usually as follows: the nozzle of the gluing component is used to gluing the paper tape after unwinding according to a predetermined glue pattern to meet the needs of the cigarette production process. At the same time, the gluing component should be cleaned in time to prevent the residual glue from drying and clogging the nozzle of the gluing component, thereby affecting the subsequent gluing quality.

[0003] In the existing process of gluing the tipping paper, most of the gluing is carried out by spraying, that is, the pressure glue is first delivered to a multi-way rotary on-off valve through a pipeline, and then sent to a distributor by the multi-way rotary on-off valve before the glue is sprayed on the gluing surface of the tipping paper. The multi-way rotary on-off valve is provided with a plurality of raised teeth or bosses at different positions on the outer circumference of its rotor. When the rotor rotates, the teeth or bosses at different positions successively open and close the corresponding glue supply pipelines of the distributor, so that a glue area and a non-glue area are formed on the gluing surface of the tipping paper to form a predetermined glue pattern. The shortcomings of the prior art are: when the glue passes through the high-speed rotating rotor, eddy currents and agitation are generated, so that when the glue reaches the inlet end of the distributor, its pressure is uncontrollable, resulting in inconsistent glue thickness sprayed by the distributor. At the same time, it is difficult to ensure the coaxiality of the rotor and the stator due to the constraints of parts processing and assembly accuracy. When the clearance between the two is required to be extremely small, the high-speed rotating rotor and the stator will produce friction. Furthermore, due to the influence of the dynamic seal on the drive shaft side, the gluing components will generate a lot of heat, which can easily cause the moisture of the residual glue on the nozzle to evaporate and condense, thereby blocking the gluing passage.

[0004] On the other hand, the existing method of cleaning the glue nozzle is to place the glue nozzle in a lifting water tank with a certain amount of water below it by rotating and moving it, and immerse the nozzle in the water with the nozzle facing downward, and then clean it with a brush. When the nozzle is facing downward, the rotor and stator of the rotating distribution valve are restricted by the clearance fit, and the density of glue is greater than that of water. Therefore, the glue in the pipeline and valve will flow into the water under the action of gravity, which not only wastes glue, but also pollutes the water in the water tank with glue, affecting the cleaning effect. Therefore, it is necessary to improve the existing technology. Summary of the invention

[0005] In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a cigarette tipping paper gluing system, which sets the gluing areas of the tipping paper as a continuous gluing area and an intermittent gluing area in the conveying direction of the tipping paper, and sets the gluing pipelines of the two areas separately and controls them individually, so that the two areas are gluing synchronously, and when the gluing operation is stopped, the gluing parts are directly cleaned and sealed without rotating to prevent residual glue from blocking the gluing passage.

[0006] The present invention is completed by the following technical scheme: A cigarette tipping paper gluing system, comprising a frame, a gluing mechanism and a cleaning mechanism arranged on the frame, characterized in that:

[0007] The gluing mechanism comprises: a rotary dispensing valve fixed on the frame, a plate-type slit nozzle embedded on the outer circle of the rotary dispensing valve, and a tipping paper tape guide roller and an eccentric roller installed on the frame and respectively located on the input and output sides of the plate-type slit nozzle;

[0008] The cleaning mechanism includes: a sewage tank located below the rotary dispensing valve, a mobile water cylinder with an open inner end and a closed outer end mounted on the rotary dispensing valve, and a water spray port located on a frame on one side of the rotary dispensing valve and facing the plate-type slit nozzle. The water spray port is located on the inner side of the mobile water cylinder after it is closed, and the water spray port is connected to a water supply pipe.

[0009] The plate-type slit nozzle of the gluing mechanism includes a die and a cover plate, wherein: the die is provided with at least one group of gluing nozzles consisting of a continuous gluing groove and an intermittent gluing groove, the top of the continuous gluing groove is provided with a continuous gluing slit connected thereto, and the top and bottom of the intermittent gluing groove are respectively provided with an intermittent gluing slit and an intermittent gluing hole connected thereto; the cover plate is provided with a continuous gluing groove, the inner end of which is connected to the continuous gluing groove on the die, and the outer end of which is connected to a continuous gluing branch pipe independent of the outside of the rotary dispensing valve.

[0010] At least one continuous gluing groove is provided on the plate-type slit nozzle concave mold of the gluing mechanism, and the specific number depends on the gluing requirements.

[0011] At least one discontinuous gluing groove is provided on the plate-type slit nozzle concave mold of the gluing mechanism, and the specific number depends on the gluing requirements.

[0012] The plate-type slit nozzle concave mold of the gluing mechanism is provided with a moisturizing groove connected to each glue outlet seam, which is used to regularly supply a small amount of clean water to each glue outlet hole and glue application groove to prevent each glue outlet hole and glue application groove from being blocked due to glue drying.

[0013] The rotary dispensing valve of the gluing mechanism comprises a stator with an axial hole therein and a rotor arranged in the stator axial hole, wherein:

[0014] The stator is provided with an intermittent glue inlet hole, the inner end of which is connected to the shaft hole of the stator, and the outer end is connected to the intermittent glue supply branch pipe. A radial glue outlet hole is provided on the wall of the stator shaft hole, and the upper end of the radial glue outlet hole is connected to the lower end of the intermittent glue inlet hole on the plate-type slit nozzle die;

[0015] The rotor consists of an opening and closing section in the middle, a sealing section at one end and a screw conveying section at the other end, and the rotor shaft diameter of the screw conveying section is smaller than the diameter of the opening and closing section, and a plurality of evenly distributed axial holes and radial holes connected to the axial holes are arranged at intervals on the outer cylindrical surface of the rotor located in the opening and closing section, and the radial holes are discontinuously connected to the lower ends of the corresponding radial glue outlet holes on the stator shaft hole wall, one end of each axial hole is closed, and the other end is set to be open and connected to the stator shaft hole; or a plurality of evenly distributed axial grooves are arranged at intervals on the outer cylindrical surface of the rotor located in the opening and closing section, and the axial grooves are discontinuously connected to the lower ends of the corresponding radial glue outlet holes on the stator shaft hole wall, one end of each axial groove is closed, and the other end is set to be open and connected to the stator shaft hole.

[0016] The stator and the rotor of the gluing mechanism are both configured as cylinders.

[0017] The diameters of the radial glue outlet holes on the stator of the glue application mechanism and the intermittent glue inlet holes on the plate-type slit nozzle die are 1 to 2 mm.

[0018] The width of the axial groove or the diameter of the axial hole and the radial hole on the rotor of the gluing mechanism is 3 to 5 mm.

[0019] The spacing distance between the axial grooves or axial holes on the rotor of the gluing mechanism depends on the width of the tipping paper sheet.

[0020] The sealing section of the rotor of the gluing mechanism includes a rotor shaft in the middle and a shaft sleeve on its periphery. The inner and outer walls of the shaft sleeve are provided with thread grooves, and the spiral direction of the thread groove is opposite to the rotation direction of the rotor. The left end of the rotor shaft extends outward and passes through the seat bearing on the frame and is connected to the motor to form an electric screw rotor. When the rotor is rotated by the motor, the glue flowing to the sealing section will flow back to the opening and closing section under the reverse conveying action of the thread groove, and then flow into the axial groove or axial hole of the rotor to prevent the glue from leaking into the seat bearing that fixes the rotor.

[0021] The screw conveying section of the rotor of the gluing mechanism includes a rotor shaft and a spiral blade arranged on the outer cylindrical surface of the rotor shaft. The spiral direction of the spiral blade is the same as the rotation direction of the rotor, so that when the rotor rotates, the glue entering the stator shaft hole is transported to the axial hole or axial groove of the opening and closing section through the spiral blade.

[0022] The intermittent glue supply branch pipe of the gluing mechanism is connected to the glue supply main pipe, the continuous glue supply branch pipe is equipped with a flow meter and a pressure regulating valve and is connected to the glue supply main pipe, the glue supply main pipe is equipped with a conventional vacuum degasser, pump, filter, and is connected to the glue box to provide glue.

[0023] The eccentric roller is installed on the frame at the paper tape output side of the plate-type slit nozzle. The gluing angle between the output side tipping paper and the plate-type slit nozzle can be adjusted by rotating the eccentric roller, and the gluing angle should be controlled within the range of -1 to 2°.

[0024] The movable water cylinder of the cleaning mechanism is set as a cylinder adapted to the rotary dispensing valve, and the inner diameter of the cylinder is larger than the outer diameter of the rotary dispensing valve, so as to be sleeved on the rotary dispensing valve with a plate-type slit nozzle and be easy to move.

[0025] The lower part of the mobile water cylinder of the cleaning mechanism is connected to the piston rod of the power cylinder fixed on the frame through a connecting piece, so that the mobile water cylinder can be reciprocated under the driving of the power cylinder.

[0026] The inner end of the mobile water cylinder of the cleaning mechanism is movably connected to a flange fixed on the frame, and a sealing ring is arranged on the flange so that the sealing ring can be used to complete the sealing when the mobile water cylinder is closed.

[0027] A drain port is provided on the frame at the lower side of the rotary dispensing valve, and the drain port is connected to the sewage tank through a drain pipe with an on-off valve thereon, and is used to drain the sewage in the mobile water cylinder into the sewage tank.

[0028] A sewage outlet is provided at the bottom of the sewage tank of the cleaning mechanism, and the sewage outlet is connected to the sewage tank through a sewage pipe and a pump, so as to discharge the sewage into the sewage tank in time for centralized treatment.

[0029] The guide roller is a roller that can be rotated in and out, vertically installed on the frame, arranged on one side of the plate-type slit nozzle and located at the tipping paper input end, so as to move the tipping paper close to and away from the gluing position to avoid interference from the tipping paper when moving the water cylinder.

[0030] The actuators such as the clean water pump, valve, power cylinder of the mobile water cylinder, sewage pump, power motor for driving the rotor, glue pump, pressure regulating valve and flow meter are all connected to the controller through electrical starting elements and wires. The controller is a conventional product.

[0031] The present invention has the following advantages and effects: from the analysis of the gluing pattern of the tipping paper, it is concluded that the gluing amount of the tipping paper mainly depends on the gluing amount of the continuous gluing area. By adopting the above scheme, the gluing paths of the continuous gluing area and the intermittent gluing area can be conveniently set completely separately, and the glue supply paths of the two areas can be controlled respectively, so that the continuous gluing area and the intermittent gluing area are precisely gluing synchronously, so that the gluing thickness of the continuous gluing area has higher consistency, and the intermittent gluing area is precisely dispensed at intervals, so that the glue does not cover or block the tipping paper air holes in the intermittent gluing area, so that the gluing quality of the tipping paper is better, and at the same time, the matching clearance between the rotor and the stator can be appropriately widened, so that the problem of glue breaking caused by glue volatilization and condensation due to friction heating of the gluing parts and blocking the nozzle can be effectively avoided.

[0032] On the other hand, the plate-type slit nozzle used for gluing can be easily rinsed and soaked in a closed manner, so that the residual glue on the nozzle is completely dissolved in the water without clogging the nozzle. After cleaning, open the mobile water cylinder to quickly discharge the sewage into the sewage tank below. It is convenient and fast, and there is no need to rotate the electric screw dispensing valve with a plate-type slit nozzle. It has a simple structure, complete cleaning, no waste of glue, and is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS

The inner end of the intermittent glue inlet hole 2210 is connected to the shaft hole 2212 of the stator 221, and the outer end is connected to the intermittent glue supply branch pipe 201. Two radial glue outlet holes 2211 are provided on the wall of the shaft hole 2212 of the stator 221.

The water spray port 334 is located on the inner side of the mobile water cylinder 31 after it is closed. The water spray port 334 is connected to a water supply pipe 333 with a valve 332 and a water supply pump 331 thereon, and the water supply pipe 333 is connected to a clean water tank 330, thereby forming a water supply pipeline 33 to provide water for cleaning; the mobile water cylinder 31 is set as a horizontal cylinder adapted to the rotary dispensing valve 22, and the inner diameter of the cylinder is larger than the outer diameter of the rotary dispensing valve 22, so that it can be sleeved on the rotary dispensing valve 22 and convenient to move; the lower part of the mobile water cylinder 31 is connected by a connecting piece 311 It is connected to the piston rod 38 of the power cylinder 30 fixed on the frame 1, so that the mobile water cylinder 31 can be reciprocated by extending or retracting the piston rod 38 under the drive of the power cylinder 30; the inner end of the mobile water cylinder 31 is movably connected to the flange 35 fixed on the frame 1, and a sealing ring 36 is provided on the flange 35, so that the mobile water cylinder 31 can be sealed by the sealing ring 36 when it is closed; a sewage pipe 34 is provided at the bottom of the sewage tank 32, and the sewage pipe 34 includes a sewage outlet arranged at the bottom of the sewage tank 32, and the sewage outlet is connected to the sewage tank 340 through a sewage pipe 342 and a sewage pump 341, so that the cleaned sewage can be discharged into the sewage tank 340 in time for centralized treatment; a drain outlet is provided on the frame 1 at the lower side of the rotary dispensing valve 22, and the drain outlet is connected to the sewage tank 32 through a drain pipe with an on-off valve 37 thereon, such as Figure 1 The guide roller 39 is connected to a connecting rod 391 fixed on the frame 1 and driven to rotate by a cylinder 392, so that the tipping paper a is glued when it is close to the plate slit nozzle 21, and the mobile water cylinder 31 is convenient to enter and complete the cleaning when it is away from the plate slit nozzle 21, so as to avoid interference of the mobile water cylinder 31 with the tipping paper a when it moves.

[0053] When the plate-type slit nozzle 21 for gluing needs to be sealed and cleaned, the guide roller 39 is driven by the cylinder 392 to rotate clockwise through the connecting rod 391, so that the tipping paper a leaves the gluing position. Figure 8, start the power cylinder 30 to close the mobile water cylinder 31, open the water spray port 334 to spray water into the mobile water cylinder 31 to rinse and soak the plate-type slit nozzle 21, so that the glue dissolves in the water and does not cause clogging to the nozzle. Before continuing to gluing, first open the on-off valve 37 between the mobile water cylinder 31 and the sewage tank 32, so that the sewage in the mobile water cylinder 31 can naturally flow into the sewage tank 32 below, and then be transported to the sewage tank 340 through the sewage outlet, sewage pipe 342, and pump 341. After the sewage is emptied, open the mobile water cylinder 31, start the cylinder 392 to make the guide roller 39 rotate counterclockwise, and place the tipping paper a close to the gluing part to carry out gluing.
