Description

Technical Field

[0001] This utility model belongs to the field of electronic cigarette technology, specifically relating to a multi-adhesive strip quantitative synchronous spraying system. Background Technology

[0002] Heated tobacco products (HNB) are a new type of tobacco product that heats tobacco using an electronic device instead of burning it, significantly reducing the release of harmful substances. HNB cigarettes typically use a forming paper to bond the end cap, smoke-generating section, small hollow section, large hollow section, and filter section together. Currently, the surface of the forming paper is coated with adhesive using multiple glue guns spraying glue in staggered segments. This method has the following problems: 1) Due to inconsistent spraying times for each glue line, the bonding effect of each glue line is inconsistent, affecting the quality of the bonding process; 2) The glue lines sprayed from multiple glue guns may contact or overlap at the edges (a 0.1mm gap is required), affecting the quality of the bonding process; 3) Adjusting the glue line width requires adjusting each glue gun individually, which is tedious, time-consuming, and difficult. Utility Model Content

[0003] In order to solve the above-mentioned technical problems in the prior art, this utility model provides a multi-adhesive strip quantitative synchronous spraying system that can simultaneously spray multiple adhesive lines onto the surface of the formed paper, ensure the quality of roll splicing and bonding, and facilitate the adjustment of adhesive line width.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a multi-adhesive strip quantitative synchronous spraying system, including a metering adhesive supply device and a composite nozzle. The bottom surface of the composite nozzle has a number of adhesive spraying holes along the length direction. The composite nozzle has an adhesive distribution channel that is simultaneously connected to all the adhesive spraying holes. The metering adhesive supply device is connected to the adhesive distribution channel through an adhesive spraying pipe. All the adhesive spraying holes are divided into several groups along the length direction. The distance between two adjacent adhesive spraying holes in the same group is m. The minimum distance between any two adjacent groups of adhesive spraying holes is n, where m is less than n.

[0005] The metering glue supply device includes a servo motor, a metering pump, and a glue tank. The servo motor is connected to the power input shaft of the metering pump in sequence through a reducer and a coupling. The bottom of the glue tank is provided with a glue discharge port. The metering pump has one inlet and four outlets. The glue discharge port is connected to the inlet of the metering pump through a glue delivery pipe. The four outlets of the metering pump are respectively connected to the composite nozzle through a glue spraying pipe.

[0006] The composite nozzle includes a nozzle body with an overall rectangular shape, the length of the nozzle body running horizontally. The adhesive spray holes are vertically arranged within the nozzle body. The bottom surface of the nozzle body has an arc-shaped structure along the front-to-back direction. A blind hole is formed in the nozzle body along the horizontal direction, which is the adhesive distribution channel. A screw plunger is provided at the port of the adhesive distribution channel. The upper port of each adhesive spray hole is connected to the adhesive distribution channel. Each adhesive spray hole is a conical hole that is narrower at the top and wider at the bottom. Four adhesive injection holes are formed above the adhesive distribution channel inside the nozzle body. The four adhesive injection holes are evenly arranged horizontally. The lower port of each of the four adhesive injection holes is connected to the adhesive distribution channel. The upper port of each of the four adhesive injection holes is connected to an adhesive spray tube.

[0007] The glue bucket is equipped with a glue-adding pipe on the upper side, and a glue-adding valve on the glue-adding pipe. The glue discharge port at the bottom of the glue bucket is connected to a glue discharge pipe, and a glue discharge valve is installed on the glue discharge pipe. A glue delivery valve is installed on the glue delivery pipe.

[0008] By adopting the above technical solution, this utility model has the following beneficial effects: 1) A composite nozzle with multiple spray holes inside is used. The outlets of these spray holes are arranged in a straight line along the bottom surface of the nozzle body. The metering pump of the metering glue supply device has four outlets, each with a roughly equal glue output. Each of the four outlets of the metering pump is connected to a glue spraying pipe, which corresponds to one of the four glue injection holes on the composite nozzle. The four glue injection holes allow for a relatively even supply of glue along the length of the glue distribution channel, resulting in a more consistent glue output from each spray hole.

[0009] 2) Because each spray nozzle in this invention is connected to a glue distribution channel and uses a metering pump, this invention is suitable for simultaneously spraying the same adhesive onto the forming paper. Each group of spray nozzles includes a different number of tapered holes, wider at the bottom and narrower at the top, spaced at intervals. During the glue spraying (coating) process, a uniform adhesive strip is formed on the forming paper. Since m is less than n, this ensures that there is approximately a 0.1mm gap between the adhesive strips sprayed from adjacent groups of spray nozzles, and that the adhesive sprayed from each nozzle in the same group is interconnected.

[0010] 3) The glue tank is made of sanitary-grade stainless steel to ensure the glue is unaffected by the environment. It is equipped with glue dispensing and discharging pipes. A high-precision metering pump is used. The amount of glue dispensed is adjusted by controlling the speed of the servo motor. The appropriate metering pump model must be selected based on the amount of glue dispensed. A single-inlet, four-outlet metering pump is selected, with each of the four outlets connected to one of the four evenly spaced glue injection holes on the composite nozzle.

[0011] 4) During the glue application process, the coupler can collect the operating speed signal of the equipment (forming paper), or the communication system can directly collect the operating speed signal and transmit it to the PLC controller. The PLC controller sends a command to the servo motor, and the servo motor drives the metering pump to match the operating speed of the equipment (forming paper). The two are interconnected to achieve a constant glue application amount at different operating speeds, thereby ensuring the uniformity of the glue strip application.

[0012] In summary, this utility model has a scientific principle and simple structure. It uses a composite nozzle to achieve consistency in the spraying time of the adhesive. There is a 0.1mm gap between the adhesive strips sprayed from two adjacent sets of spray nozzles to ensure the quality of the roll splicing. When adjusting the alignment with the adhesive spraying of the forming paper, only the composite nozzle needs to be adjusted to adjust the position of the different adhesive strips as a whole, which is convenient to operate and saves time.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] like Figures 1-5 As shown, the multi-adhesive strip quantitative synchronous spraying system of this utility model includes a metering adhesive supply device and a composite nozzle 1. The bottom surface of the composite nozzle 1 has a plurality of adhesive spraying holes 2 along the length direction. The composite nozzle 1 has an adhesive distribution channel 3 that is simultaneously connected to all the adhesive spraying holes 2. The metering adhesive supply device is connected to the adhesive distribution channel 3 through an adhesive spraying pipe 4. All the adhesive spraying holes 2 are divided into several groups along the length direction. The distance between two adjacent adhesive spraying holes 2 in the same group is m. The minimum distance between any two adjacent groups of adhesive spraying holes 2 is n, where m is less than n.

[0016] The metering glue supply device includes a servo motor 5, a metering pump 6, and a glue tank 7. The servo motor 5 is connected to the power input shaft of the metering pump 6 in sequence through a reducer 17 and a coupling. The bottom of the glue tank 7 is provided with a glue discharge port. The metering pump 6 has one inlet and four outlets. The glue discharge port is connected to the inlet of the metering pump 6 through a glue delivery pipe 8. The four outlets of the metering pump 6 are respectively connected to the composite nozzle 1 through a glue spraying pipe 4.

[0017] The composite nozzle 1 includes a nozzle body 9 with an overall rectangular shape. The length of the nozzle body 9 is along the left-right direction. The glue spraying holes 2 are vertically arranged inside the nozzle body 9. The bottom surface of the nozzle body 9 has an arc structure along the front-back direction. A blind hole (for easy processing) is opened in the nozzle body 9 along the left-right direction. The blind hole is the glue distribution channel 3. The glue distribution channel 3 is provided with a screw plunger 10 at its port. The upper port of each glue spraying hole 2 is connected to the glue distribution channel 3. Each glue spraying hole 2 is a conical hole that is narrower at the top and wider at the bottom. Four glue injection holes 11 are opened above the glue distribution channel 3 inside the nozzle body 9. The four glue injection holes 11 are evenly arranged along the left-right direction. The lower port of the four glue injection holes 11 is connected to the glue distribution channel 3. The upper port of each of the four glue injection holes 11 is connected to a glue spraying tube 4.

[0018] The glue tank 7 is provided with a glue adding pipe 12 on the upper side, and a glue adding valve 13 is provided on the glue adding pipe 12. The glue discharge port at the bottom of the glue tank 7 is connected to a glue discharge pipe 14, and a glue discharge valve 15 is provided on the glue discharge pipe 14. A glue delivery valve 16 is provided on the glue delivery pipe 8.

[0019] The working principle and beneficial effects of this utility model are as follows: 1) A composite nozzle 1 is used, with multiple spray holes 2 inside. The outlets of the multiple spray holes 2 are arranged in a straight line along the bottom surface of the nozzle body 9. The metering pump 6 of the metering glue supply device has four outlets, and the glue output of each outlet is basically equal. The four outlets of the metering pump 6 are respectively connected to a spray pipe 4, which is connected to the four glue injection holes 11 on the composite nozzle 1 in a one-to-one correspondence. The arrangement of the four glue injection holes 11 can simultaneously supply a relatively uniform amount of glue along the length of the glue distribution channel 3, so that the amount of glue sprayed from each spray hole 2 is also relatively consistent.

[0020] 2) Because each spray nozzle 2 in the composite nozzle 1 is connected to a glue distribution channel 3 and uses a metering pump 6, this invention is suitable for simultaneously spraying the same adhesive onto the forming paper. Each group of spray nozzles 2 includes a different number of tapered holes with a coarser bottom and a thinner top, spaced at intervals on the left and right. During the glue spraying (coating) process, a uniform adhesive strip is formed on the forming paper. m is less than n, which ensures that there is an interval of about 0.1mm between the adhesive strips sprayed from two adjacent groups of spray nozzles 2, and that the adhesive sprayed from each spray nozzle 2 in the same group of spray nozzles 2 is interconnected.

[0021] 3) The glue tank 7 is made of sanitary-grade stainless steel to ensure that the glue is not affected by the environment. It is equipped with a glue dispensing pipe 12 and a glue discharging pipe 14. A high-precision metering pump 6 is used. The amount of glue dispensed is adjusted by controlling the speed of the servo motor 5. The appropriate model of metering pump 6 needs to be selected according to the amount of glue dispensed. A single-inlet, four-outlet metering pump 6 is selected, with the four outlets connected to the four evenly spaced glue injection holes 11 on the composite nozzle 1.

[0022] 4) During the glue application process, the coupler can collect the operating speed signal of the equipment (forming paper), or the communication system can directly collect the operating speed signal and transmit it to the PLC controller. The PLC controller sends a command to the servo motor 5, and the servo motor 5 drives the metering pump 6 to match the operating speed of the equipment (forming paper). The two are interconnected to achieve a constant glue application amount at different operating speeds, thereby ensuring the uniformity of the glue strip application.

[0023] In this invention, the adhesive spraying holes 2 in the composite nozzle 1 are divided into three groups: the left group includes one adhesive spraying hole 2, the right group includes two adhesive spraying holes, and the rest are the middle group.

[0024] In this invention, the servo motor 5, reducer 17, coupling, metering pump 6, various valves, and pipe joints are all existing technologies and are commercially available; their structure and working principle will not be described in detail. Furthermore, the automatic control of the servo motor 5's speed does not involve any new computer program.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
