Description

Technical Field

[0001] The invention relates to the technical field of gluing of tipping paper of a tobacco tipping machine, in particular to a gluing device of a tipping machine which cuts a double-length cigarette rod into two single-length cigarette rods during cigarette production. Background Art

[0002] In the tobacco production process, there is a link in which a piece of paper needs to be wrapped on the cigarette filter. This type of paper is called tipping paper 24. Before wrapping the cigarette filter, a layer of glue needs to be sprayed on the surface of the tipping paper 24.

[0003] Therefore, there is a gluing device for the splicing machine, and the existing gluing device is mainly composed of a main box, a glue roller device, an oscillating roller mechanism, a glue cylinder positioning device, a glue roller transmission, a paper lifting roller mechanism, a paper guide block mechanism, etc. The gluing device is an important part of the splicing machine, and its function is to align the tipping paper (i.e., the tipping paper 24) along the center line of the unit, send a glue demand signal to the glue supply system and receive glue, form a glue pile of appropriate size on the two glue rollers, and apply a layer of glue with uniform thickness and controllable glue area to the tipping paper in a synchronous or asynchronous manner to ensure the speed synchronization of the tipping paper when cutting, and when the tipping paper does not need to be glued, it is separated from the glue area and the running status of the tipping paper is always detected.

[0004] However, the existing gluing devices all adopt the roller coating method. The rubber rollers appear in pairs, consisting of a control rubber roller and a coating rubber roller. There is a proper amount of glue accumulation in the upper area between the two rubber rollers, and the excess glue is stored in the glue storage area of ​​the glue cylinder. The process groove set by the controlled rubber roller is taken up and transferred to the coating rubber roller. The coating rubber roller coats the tipping paper with a layer of glue with uniform thickness and controllable glue area. The structural glue is in direct contact with the air, which is easy to cause glue crusting and contamination. In addition, there is a proper amount of glue accumulation in the upper area between the two rubber rollers. When the two rubber rollers are running at high speed, the glue will accumulate. During rotation, the glue is sheared and thinned during the extrusion and counter-rotation of the rubber roller, which destroys the performance of the glue and causes the initial adhesion of the glue applied by the rubber roller to the tipping paper 24 to decrease. In addition, when the machine is stopped, in order to keep the glue from drying out, the rubber roller always keeps rotating through transmission. At this time, the degree of glue damage is even greater. Especially when the machine is shut down for a long time for maintenance, the glue will be in direct contact with the air for a long time, which makes it easier for the glue to crust and become contaminated. The above-mentioned problems affect the quality of gluing and splicing on the equipment, resulting in a high frequency of maintenance. Therefore, it is urgent to solve the above-mentioned problems.

[0005] In summary, the prior art has the following problems: first, when adding glue, the operator needs to pour the glue into the glue storage barrel from the top of the storage barrel mouth. The glue storage barrel is deep and in direct contact with the air, and it is easy to produce flocculent rubber above the glue liquid surface, and even the glue block will deteriorate. When the glue is poured in, it will impact the glue in the barrel, and the flocculent rubber will be broken up and mixed into the glue, which will reduce the initial adhesion of the glue and affect the stability of the glue quality. These unstable glues in contact with the air enter the gluing mechanism, thereby affecting the gluing and splicing quality. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] See also Figure 1-11The present embodiment discloses a gluing device of a mounting machine, comprising a main housing 1, on which a glue spraying mechanism is arranged, the glue spraying mechanism comprising a main motor 2, a main shaft 3, a bellows coupling 4, an outer sleeve 5, a connector 6, a cylindrical valve body 12, a valve core rotor 13, a valve seat 14, a rotating motor 20, a protective sleeve 26, and a gear sleeve 27, wherein the rotating motor 20 is fixed to the back of the main housing 1, the bellows coupling 4 is rotatably connected in the protective sleeve 26, the output shaft of the main motor 2 is connected to one end of the bellows coupling 4, the other end of the bellows coupling 4 is connected to one end of the main shaft 3, the outer sleeve 5 is movably sleeved on the outside of the protective sleeve 26 and the main shaft 3, and the end of the protective sleeve 26 away from the outer sleeve 5 is provided with The gear sleeve 27, the other end of the main shaft 3 is partially exposed from the outer sleeve 5 and connected to the valve core rotor 13 through the connector 6, the cylindrical valve body 12 is sleeved outside the valve core rotor 13, and a glue spraying chamber is formed between the cylindrical valve body 12 and the valve core rotor 13, the valve seat 14 is connected to an end face of the cylindrical valve body 12 away from the outer sleeve 5, and a total glue spraying hole 141 and a total water spraying hole 142 communicating with the glue spraying chamber are provided on the valve seat 14, and the total glue spraying hole 141 is connected to the glue supply mechanism, and an arc-shaped notch 121 is provided on the cylindrical valve body 12, and a glue spraying assembly is fixed in the arc-shaped notch 121, and the glue spraying assembly includes a glue spraying seat 15 and a right-angled triangle water spraying seat 16, and one end face of the glue spraying seat 15 is opposite to one waist face of the water spraying seat 16 The invention relates to a strip-shaped nozzle 17, wherein the bottom of the glue spray seat 15 is provided with one or more first glue spray holes 18, and the side of the glue spray seat 15 is provided with one or more second glue spray holes 19 connected with the first glue spray holes 18, and all the second glue spray holes 19 are arranged in the strip-shaped nozzle 17, and the bottom of the water spray seat 16 is provided with one or more high-pressure water spray holes 8, and all the high-pressure water spray holes 8 are connected with the total water spray hole 142, and the external gear part on the gear sleeve 27 is connected with the output shaft of the rotating motor 20 through a gear transmission. In this embodiment, one end of the gear sleeve 27 is fixedly connected with one end of the protective sleeve 26, and the other end of the protective sleeve 26 is fixedly connected with one end of the outer sleeve 5, and the other end of the outer sleeve 5 is fixedly connected with the cylindrical valve body 12, and the gear sleeve 27 is fixedly connected with one end of the protective sleeve 26. The specific way in which the external gear part on the wheel sleeve 27 is connected to the output shaft of the rotating motor 20 through gear transmission is that a transmission gear is fixed on the output shaft of the rotating motor 20, and a transmission gear belt 25 is connected between the transmission gear and the external gear part on the gear sleeve 27. When working, the rotating motor 20 works to drive the gear transmission to rotate, and the gear sleeve 27 is synchronously driven to rotate under the action of the transmission gear belt 25, and the cylindrical valve body 12 at the front end is synchronously driven to rotate from the initial state to the glue spraying station. How to ensure that the cylindrical valve body 12 stops when it rotates to the initial state or stops when it rotates to the glue spraying station, the rotation angle of the rotating motor 20 can be pre-set, which is a conventional technology for those skilled in the art.Therefore, no detailed description is given here.

[0031] Preferably, there are eight second glue spray holes 19, the width of the long strip nozzle 17 is the width of the tipping paper 24 minus 0.15 mm, the depth of the glue outlet is 0.18 mm, and a 1.2 mm thick partition layer 191 is provided between two adjacent second glue spray holes 19. Figure 8 It can be seen that the gap of the glue spraying gap 151 is small near the second glue spraying hole 19 and large near the outlet. Then, during the high-pressure rotation of the internal valve core rotor 13, the final glue spraying area is larger under high pressure.

[0032] Preferably, in order to avoid excessive glue spraying, a glue spraying notch 151 corresponding to each second glue spraying hole 19 is provided on the side of the glue spraying seat 15. After a side of the glue spraying seat 15 with the glue spraying notch 151 abuts against a waist surface of the water spraying seat 16, all the glue spraying notches 151 constitute the elongated nozzle 17. Through the above-mentioned structural arrangement, the glue sprayed from each second glue spraying hole 19 can be more even and not excessive.

[0033] Preferably, in order to realize intermittent glue spraying, the valve core rotor 13 is provided with one or more glue blocking groups 131 in an annular manner, and each glue blocking group 131 includes one or more small blocks 1311 that can block the corresponding second glue spraying hole 19. Since it is not necessary to spray glue on one side of all the conveyed kraft paper 24, but only to spray glue on the position of the kraft paper 24 in a specified area, the structure arranges several glue blocking groups 131 in an annular manner on the valve core rotor 13. As the valve core rotor 13 rotates to when one of the glue blocking groups 131 blocks the second glue spraying hole 19, the current glue spraying The surface of the kraft paper 24 in the glue spraying area will not be sprayed with glue. As the valve core rotor 13 continues to rotate, when the second glue spraying hole 19 is exposed, the surface of the kraft paper 24 in the current glue spraying area will be sprayed with glue. Therefore, the spacing between the two adjacent groups of glue blocking groups 131 set on the valve core rotor 13 is exactly the length of the kraft paper 24 in the glue spraying area that does not need to be sprayed with glue - that is, the glue-free area - and serves as the later cutting area. In this way, the spacing between the two adjacent groups of glue blocking groups 131 can be set in advance according to requirements, and the small block 1311 can also avoid the problem of glue bubbling under high pressure when not in use.

[0034] Preferably, in order to improve the cleaning of the long strip nozzle 17 and avoid the long strip nozzle 17 being blocked by residual glue and affecting the glue spraying, a cleaning mechanism 7 for cleaning the long strip nozzle 17 is also included. The cleaning mechanism 7 is located below the cylindrical valve body 12, and the cylindrical valve body 12 is in the initial state. The glue spraying assembly is placed in the cleaning mechanism 7. The cleaning mechanism 7 includes a water tank 701, a scraper 702 and a cylinder 703. The scraper 702 is located in the water tank 701. The water tank 701 is arranged at an angle, and a U-shaped opening 7011 is arranged above the water tank 701, and the cylinder 703 is fixed on the back of the main box body 1, and the piston rod of the cylinder 703 is connected with the scraper 702 which can be moved back and forth in the water tank 701, and the scraper 702 can clean the long strip nozzle 17 in the water tank 701 when it is moved. The above structure can further avoid the problem of clogging of the outlet of the spray assembly or crusting at the long strip nozzle 17 by adding a cleaning mechanism 7.

[0035] like Fig.10 , Fig.11 As shown, the scraper 702 is fixed on a push rod 7031 movably plugged into the water tank 701, and the push rod 7031 partially extends out of the water tank 701 and the main box body 1 and the piston rod of the cylinder 703 on the back of the main box body 1. The above working principle is as follows: when the glue spraying assembly is not in use, the rotating motor 20 drives the entire glue spraying mechanism to rotate from the glue spraying station to the initial state, that is, the glue spraying assembly is placed in the cleaning mechanism 7, and the cylinder 703 is driven to work at this time. When the piston rod of the cylinder 703 works, it drives the scraper 702 to move back and forth. Since the glue spraying assembly is in the initial state, the elongated nozzle 17 is just located on the moving track of the scraper 702, so when the scraper 702 moves back and forth, it can remove the glue remaining on the surface of the elongated nozzle 17. Scraping is performed to prevent glue liquid from remaining on the surface of the long strip nozzle 17 and clogging the glue spray head (i.e., the long strip nozzle 17), which will affect the occurrence of problems with glue spraying in the later stage. At the same time, when the scraper 702 is working, the high-pressure water pump 9 is also driven to work, so that the high-pressure water spray hole 8 sprays water at high pressure. The high-pressure sprayed water will impact the water in the water tank 701, causing the water in the water tank 701 to form waves, thereby adding fuel to the fire and further ensuring that the scraper 702 carries water while scraping the long strip nozzle 17, thereby further improving the cleaning effect of the long strip nozzle 17. Therefore, through this structure, the unused long strip nozzle 17 can be flushed to prevent glue liquid from remaining on the surface of the long strip nozzle 17 and clogging the glue spray head (i.e., the long strip nozzle 17), which will affect the occurrence of problems with glue spraying in the later stage.

[0036] Preferably, a high-pressure water pump 9 is provided on the main box body 1, and the output end of the high-pressure water pump 9 is connected to the main water spray hole 142. The high-pressure water pump 9 is installed on the back of the main box body 1, and the specific structure of the high-pressure water pump 9 belongs to the prior art. At the same time, how the high-pressure water pump 9 is installed on the main box body 1 is a conventional technology for those skilled in the art, so it is not described in detail. In the later stage, the input end of the high-pressure water pump 9 can be directly connected to the water storage tank 21 below. If it is connected to the water storage tank 21, a filter can be added at the connection between the water storage tank 21 and the high-pressure water pump 9. Considering that, or a new water tank is added, the new water tank is directly installed on the back of the main box body 1, and clean purified water is used in the new water tank to avoid impurities in the water, which may cause clogging of the water spray hole.

[0037] like Fig. 9 As shown, as a preference, it also includes two-way blowing devices 11, wherein one blowing device 11 is arranged above the water tank 701 and is used to blow air to the long strip nozzle 17 after cleaning, and the other blowing device 11 is arranged on the glue spraying station, and the blowing device 11 includes a long blowing pipe 111 fixed to the main box body 1, and a long strip blowing hole 112 is arranged on the long blowing pipe 111. In this embodiment, since the glue spraying component is in the water tank 701 when not in use, when the glue spraying component needs to be used, during the process of the entire glue spraying mechanism rotating from the initial position to the glue spraying station, the glue spraying component slowly separates from the water tank 701, and a small amount of water will remain in the glue spraying component. Therefore, by adding two-way blowing devices 11, one of which is located above the water tank 701 and placed on the spray station On the rotating trajectory of the glue component, the function is to blow air on the surface of the glue spraying component coming out of the water tank 701, that is, it can dry the surface of the glue spraying component, and at the same time blow away the dust or impurities remaining on the surface of the glue spraying component. At the same time, another blowing device 11 is located below the glue spraying station, which can blow air on the surface of the valve seat 14 to remove the dust or impurities remaining on the surface of the valve seat 14, and avoid the valve seat 14 from bringing dust into the water tank 701 during the rotation of the water tank 701. In this embodiment, the two blowing devices 11 are both connected to an existing blowing power device 22 (which can be a blower or a fan), and the blowing power device is installed on the back of the main box body 1. As for how the blowing power device 22 is installed on the main box body 1, this belongs to conventional technology for technicians in this field.

[0038] Preferably, a water tank 21 connected to the water tank 701 is also provided on the main box body 1, and the output port of the water tank 21 is connected to the water supply pump 10, and the output port of the water supply pump 10 is connected to the water tank 701. The water tank 21 has a water inlet on the top, and in this embodiment, it should be noted that the water tank 21 and the water supply pump 10 are installed on the back of the main box body 1. In this embodiment, a controller 23 is also provided on the back of the main box body 1, and the controller 23 is electrically connected to the main motor 2, the rotating motor 20, the water supply pump 10, the cylinder 703, and the blowing power device 22. The operation of each device is controlled by the controller 23. As for the specific structure and model of the controller 23, the water tank 21 and the water supply pump 10, they belong to the prior art. At the same time, how the controller 23, the water tank 21 and the cylinder 703 are installed on the main box body 1 belongs to conventional technology for those skilled in the art.

[0039] The specific working principle of this structure is as follows: First of all, it is mainly explained that this structure is an improvement on the glue spraying component. As for other structures of the main box 1 such as the glue supply mechanism, the kraft paper 24 conveying mechanism, the paper lifting mechanism, etc., they all belong to the conventional technology in this field, so they are not described in detail. The working mode is that the kraft paper 24 is transported by the kraft paper 24 conveying mechanism on the main box 1, and the glue spraying mechanism is arranged on the conveying track of the kraft paper 24 conveying mechanism of the glue spraying mechanism. When it is necessary to spray glue on the kraft paper 24, the controller 23 controls the rotating motor 20 to rotate, and drives the glue spraying component from the initial state (when the entire glue spraying component is not in use, the glue spraying component is in the water tank 701) to rotate to the conveying track of the kraft paper 24, that is, the glue spraying station. At this time, the rotating motor 20 stops working, and the main motor 2 is allowed to work, driving the corrugated coupling 4 to rotate, and synchronously driving the main shaft 3 to rotate. The main shaft 3 drives the valve core rotor 13 to rotate at high speed. At the same time, since the total glue spraying hole 141 is connected to the glue supply mechanism, as for how the total glue spraying hole 141 The connection with the glue supply mechanism belongs to the conventional technology in this field, so it will not be described in detail. At this time, the glue is fed into the main glue spray hole 141, and the glue enters the glue spray chamber between the cylindrical valve body 12 and the valve core rotor 13. Under the action of the high-speed rotation of the valve core rotor 13, the glue is squeezed out and passes through the first glue spray hole 18 and the second glue spray hole 19 in turn, and then is sprayed from the long strip nozzle 17 and sprayed on the surface of the kraft paper 24 conveyed by the kraft paper 24 conveying mechanism. In this way, the intermittent glue spraying operation on the surface of the kraft paper 24 is realized by this cyclic operation. Compared with the existing technology: the glue is coated on the surface of the kraft paper 24 by rotating two rubber rollers. The present structure adopts a high-pressure glue spraying method, and the unused glue will not directly contact with the air, avoiding the problem of glue crusting and pollution. In addition, the high-pressure glue spraying is used, and the glue spraying is more uniform, and there is basically no damage to the glue. Therefore, the glue spraying method of the present structure can further avoid direct contact between the glue and the air, causing the problem of glue crusting and pollution. At the same time, the glue will not be squeezed by the two rubber rollers, resulting in the problem of glue deterioration.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
