Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and in particular to a double-horizontal carton sealing machine and a carton sealing method of the double-horizontal carton sealing machine. Background Art

[0002] A carton sealer is a device that seals the opening of a carton with tape to complete product packaging. Today's carton sealers have a variety of styles to meet different carton sealing requirements. Cartons enter the carton sealer from one end, and the machines set at different positions complete the tape sealing of different positions of the carton. For some products with special shapes, material properties or sizes, there are also special requirements for the shape, material properties or size of the cartons used for packaging. Therefore, it is also necessary to synchronously tape the opposite sides of the cartons that have completed the tape on the top cover, that is, tape the two sides of the same tape position at the same time, so as to make the cartons containing products more secure, reduce the risk of damage to the cartons during handling or transportation, and ensure the quality of the products inside the cartons.

[0003] The defect of the above-mentioned carton sealing machine is that only one taping station and a corresponding synchronous taping mechanism on the opposite side are provided, that is, only one synchronous taping action is performed on the side of the carton, which may result in inadequate taping and the packaging quality of the carton cannot be guaranteed. Moreover, during the taping process, in order to ensure that the tape does not wrinkle or stick to the carton as much as possible, the conveyor belt needs to be slowed down, thereby reducing the efficiency of taping. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, one of the objects of the present invention is to provide a double horizontal carton sealing machine, by adjacently arranging a first synchronous gluing tape mechanism and a second synchronous gluing tape mechanism along the direction of the feed channel, and gluing the side edges of the carton twice in sections through the first conveyor belt and the second conveyor belt, thereby reducing the situation of inadequate gluing and ensuring the packaging quality of the carton. The speed of the conveyor belt during the gluing process is adjusted by the control system to ensure that the tape does not wrinkle and stick, while improving the efficiency of gluing.

[0005] In order to overcome the shortcomings of the prior art, the second purpose of the present invention is to provide a carton sealing method for a double horizontal carton sealing machine, which controls the continuous operation of the first synchronous tape sticking mechanism and the second synchronous tape sticking mechanism through a control system, and performs two segmented glue sticking on the side of the carton to reduce the occurrence of inadequate gluing and ensure the packaging quality of the carton. At the same time, the speed of the conveyor belt during the gluing process is adjusted to ensure that the tape does not wrinkle and stick, while improving the efficiency of taping.

[0006] One of the purposes of the present invention is achieved by the following technical solution:

[0007] A double horizontal carton sealer, comprising a frame, a conveyor belt, a first synchronous tape sticking mechanism, a second synchronous tape sticking mechanism and a control system,

One end of the second spring is connected to the first spring, and the other end is connected to the first blade adjustment component. The first blade is arranged on the first blade adjustment component and is used for adjusting the angle of the first blade. The first cylinder drives the first mounting plate to move towards the feeding channel so that the first glue feeding roller and the first glue discharging roller are located inside the feeding channel. The sensor is used for collecting the first conveying speed and transmitting it to the control system. The control system controls the first glue feeding roller to perform the first tape sticking on the first tape sticking position of the carton at the first conveying speed. The first conveying speed is the running speed of the first conveyor belt at the first synchronous tape sticking station;

One end of the fourth spring is connected to the third spring, and the other end is connected to the second blade adjustment assembly. The second blade adjustment assembly is provided with the second blade and is used for adjusting the angle of the second blade. The second air cylinder drives the second mounting plate to move towards the feeding channel so that the second glue - feeding roller and the second glue - discharging roller are located inside the feeding channel.

[0012] The control system determines the first transmission time according to the first transmission distance and the first transmission speed, and adjusts the second transmission speed according to the first transmission time, the second transmission distance, and a preset distance. After the first transmission time when the first synchronous tape - sticking mechanism starts tape - sticking, the control system controls the second synchronous tape - sticking mechanism to perform a second tape - sticking on the carton at the second transmission speed. The first transmission distance is the distance from the first glue - feeding roller to the first glue - discharging roller at the second tape - sticking position on the side of the carton; the first transmission time is the time required for the second tape - sticking position on the side of the carton to reach the position of the first glue - discharging roller from the position of the first glue - feeding roller; the second transmission distance is the distance from the second glue - feeding roller to the second glue - discharging roller at the second tape - sticking position on the side of the carton; the preset distance is the distance between the first glue - discharging roller and the second glue - feeding roller and is greater than the distance between the first conveyor belt and the second conveyor belt; the second transmission speed is the speed of the second conveyor belt running at the second synchronous tape - sticking station.

[0013] Further, the sensor is a magnetoelectric sensor or a Hall sensor.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0047] Figures 1-3 The double horizontal carton sealing machine of the present invention includes a frame, a conveyor belt, a first synchronous tape sticking mechanism, a second synchronous tape sticking mechanism, and a control system.

[0048] In this embodiment:

[0049] As Figures 1-3 shown, the frame 10 is provided with a feeding channel 11. Along the length direction of the feeding channel 11, a first synchronous tape sticking station and a second synchronous tape sticking station are successively arranged. The first synchronous tape sticking mechanism 30 is arranged on both sides of the first synchronous tape sticking station, and the second synchronous tape sticking mechanism 40 is arranged on both sides of the second synchronous tape sticking station.

[0050] The conveyor belt 20 includes a first conveyor belt 21 and a second conveyor belt 22, which are used to convey cartons in sections. The first conveyor belt 21 and the second conveyor belt 22 are both rotatably arranged in the feeding channel 11. The first synchronous tape pasting station is located on the first conveyor belt 21, and the second synchronous tape pasting station is located on the second conveyor belt 22. There are a first tape pasting position and a second tape pasting position on the side of the carton. In a preferred embodiment, a height adjustment component can be arranged above the conveyor belt 20 to adjust its height relative to the conveyor belt 20 to adapt to cartons of different height dimensions.

[0051] The first synchronous tape pasting mechanism 30 includes a first mounting plate 301, a first fixed glue roller 302, a first glue feeding roller 303, a first glue discharging roller 304, a first glue guiding roller 305, a first blade 307, a first cylinder 308, a first spring 309, a second spring 310, a first connecting rod 311, a first cutting adjustment component 312, and a sensor 313.

[0052] The first fixed glue roller 302, the first glue feeding roller 303, the first glue discharging roller 304, and the first glue guiding roller 305 are arranged on the first mounting plate 301 through a plurality of first connecting rods 311. In this embodiment, the position of the first glue feeding roller 303 is fixed, and the distance between the first glue discharging roller 304 and the first glue discharging roller 304 is adjusted through the first connecting rod 311. Both the first glue feeding roller 303 and the first glue discharging roller 304 are hard knurled rollers to ensure that when the roller contacts the glue surface of the tape, the tape will not stick and wind around the roller.

[0053] The first fixed glue roller 302 is used to place the tape. One end of the first spring 309 is connected to the first glue discharging roller 304, and the other end is connected to the second spring 310. One end of the second spring 310 is connected to the first spring 309, and the other end is connected to the first cutting adjustment component 312. The first blade 307 is arranged on the adjustment component of the first blade 307 and is used to adjust the angle of the first blade 307 to adapt to cartons with different side shapes. Specifically, as the carton advances, the tape is continuously stretched and unrolled and adhered to the carton. When the carton leaves the first glue discharging roller 304, the first spring 309 drives the first blade protection plate 306 and the first cutting adjustment component 312 to act through the second spring 310. The first blade 307 cuts off the tape, and the last short section of the tape is adhered to the front end of the carton by relying on the first glue discharging roller 304.

[0054] The first cylinder 308 drives the first mounting plate 301 to move towards the feeding channel 11 so that the first glue feeding roller 303 and the first glue discharging roller 304 are located inside the feeding channel 11.

[0055] The sensor 313 is used to collect the first conveying speed and transmit it to the control system. The control system controls the first glue feeding roller 303 to apply the first tape to the first tape sticking position of the carton at the first conveying speed, and the first conveying speed is the speed at which the first conveyor belt 21 runs at the first synchronous tape sticking station. In this embodiment, the sensor 313 is a magnetoelectric sensor 313 or a Hall sensor 313. In other embodiments, the first conveying speed can also be obtained through an encoder length measuring roller.

[0056] The second synchronous tape sticking mechanism 40 includes a second mounting plate 401, a second tape fixing roller 402, a second glue feeding roller 403, a second glue discharging roller 404, a second glue guiding roller 405, a second blade 407, a second cylinder 408, a third spring 409, a fourth spring 410, a second connecting rod 411, and a second cutting adjustment assembly 412.

[0057] The second tape fixing roller 402, the second glue feeding roller 403, the second glue discharging roller 404, and the second glue guiding roller 405 are arranged on the second mounting plate 401 through a plurality of second connecting rods 411. In this embodiment, the position of the second glue feeding roller 403 is fixed, and the distance between the second glue discharging roller 404 and the second glue discharging roller 404 is adjusted through the second connecting rod 411. Both the second glue feeding roller 403 and the second glue discharging roller 404 are hard knurled rollers to ensure that when the roller contacts the glue surface of the tape, the tape will not stick and wind around the roller.

[0058] The second tape fixing roller 402 is used to place the tape. One end of the third spring 409 is connected to the second glue discharging roller 404, and the other end is connected to the fourth spring 410. One end of the fourth spring 410 is connected to the third spring 409, and the other end is connected to the second blade adjustment assembly. The second blade adjustment assembly is provided with the second blade 407 and is used to adjust the angle of the second blade 407 to adapt to cartons with different side shapes. Specifically, as the carton advances, the tape is continuously stretched and unrolled and adheres to the carton. When the carton leaves the second glue discharging roller 404, the third spring 409 drives the second blade protection plate 406 and the second cutting adjustment assembly 412 to act through the fourth spring 410. The second blade 407 cuts off the tape, and the last short tape is adhered to the front end of the carton by the second glue discharging roller 404.

[0059] The second cylinder 408 drives the second mounting plate 401 to move towards the feeding channel 11 so that the second glue feeding roller 403 and the second glue discharging roller 404 are located inside the feeding channel 11. In this embodiment, the first tape fixing roller 302 and the second tape fixing roller 402 are located between the first cylinder 308 and the second cylinder 408, making the layout of the components reasonable, the tape installation convenient, facilitating the subsequent replacement of the used tape, and improving the case sealing efficiency.

[0060] The control system determines the first conveying time according to the first conveying distance and the first conveying speed, and adjusts the second conveying speed according to the first conveying time, the second conveying distance, and the preset distance. After the first conveying time when the first synchronous tape - sticking mechanism 30 starts sticking the tape, the control system controls the second glue - feeding roller 403 to perform the second tape - sticking on the carton at the second conveying speed. The control system determines the second conveying time according to the second conveying speed and the second conveying distance. After the second conveying time when the second synchronous tape - sticking mechanism 40 starts sticking the tape, place the next carton onto the first conveyor belt 21, and repeat the above steps.

[0061] The first conveying distance is the distance from the first glue - feeding roller 303 to the first glue - discharging roller 304 at the second tape - sticking position on the side of the carton; the first conveying time is the time required for the second tape - sticking position on the side of the carton to reach the position of the first glue - discharging roller 304 from the position of the first glue - feeding roller 303; the second conveying distance is the distance from the second glue - feeding roller 403 to the second glue - discharging roller 404 at the second tape - sticking position on the side of the carton; the preset distance is the distance between the first glue - discharging roller 304 and the second glue - feeding roller 403, and this distance is greater than the distance between the first conveyor belt 21 and the second conveyor belt 22; the second conveying speed is the speed at which the second conveyor belt 22 operates at the second synchronous tape - sticking station; the second conveying time is the time required for the second tape - sticking position on the side of the carton to reach the position of the second glue - discharging roller 404 from the position of the second glue - feeding roller 403.

[0062] In this application, by arranging the first synchronous tape - sticking mechanism 30 and the second synchronous tape - sticking mechanism 40 adjacent to each other along the direction of the feeding channel 11, and performing two - stage tape - sticking on the side of the carton through the first conveyor belt 21 and the second conveyor belt 22, the situation of incomplete sticking is reduced, ensuring the packaging quality of the carton. By adjusting the speed of the second conveyor belt 22 during the tape - sticking process through the control system, while ensuring that the tape does not wrinkle and stick together, the efficiency of tape - sticking is improved; in this application, by adjusting the distance between the first glue - feeding roller 303 and the first glue - discharging roller 304, and the distance between the second glue - feeding roller 403 and the second glue - discharging roller 404, it can adapt to cartons with different side lengths, and has a wide range of applications.

[0063] As Figures 4-5 shown, this application also provides a cartoning method for a double - horizontal cartoning machine. Using any of the above - mentioned double - horizontal cartoning machines, it includes the following steps:

[0064] Pre - installation: Place the tape on the first tape - fixing roller 302 of the first mounting plate 301, and lead it out from the first glue - feeding roller 303 through several first glue - guiding rollers 305; place the tape on the second tape - fixing roller 402 of the second mounting plate 401, and lead it out from the second glue - feeding roller 403 through several second glue - guiding rollers 405.

[0065] First taping: Place the cardboard box at the entrance of the feeding channel 11. The control system senses the signal, controls the first cylinder 308 to extend, and drives the first mounting plate 301 to move forward so that the first glue feeding roller 303 and the first glue discharging roller 304 are inside the feeding channel 11. The sensor 313 collects the first conveying speed and transmits it to the control system. The control system controls the first glue feeding roller 303 to perform the first taping on the first taping position of the cardboard box at the first conveying speed;

[0066] First tape cutting: When the second taping position on the side of the cardboard box touches the first glue discharging roller 304, the control system senses the signal, controls the first cutting adjustment component 312 to adjust the cutting angle of the first blade 307.
