Description

Technical Field

[0001] The utility model relates to the field of packaging, in particular to an automatic box sealing device for cartons. Background Art

[0002] In the field of carton packaging, for example, in the tobacco industry, the process of packing and sealing cigarette strips is usually done manually, so the degree of automation of the production line is very low. In the manual packing method, after the cigarette strips come out of the rolling and packaging machine, they pass through the belt conveyor, blocking mechanism, cigarette pushing mechanism, etc., and then go to the manual cigarette picking platform for sorting. When sorting the cigarette strips, the manual workers also need to check the appearance quality of the cigarette strips with the naked eye and judge whether they are qualified based on experience. There are many disadvantages in manual packing and sealing, such as low sealing efficiency and possible defects in the shape of the sealed box, which is not conducive to people's use.

[0003] With the continuous development of science and technology, automatic sealing devices for sealing cartons have emerged. However, there are many shortcomings in the existing automatic sealing devices. For example, the tape applied to the sides and top of the carton cannot be completely adhered to the surface of the carton, and even the tape may be twisted and deformed on the surface of the carton, resulting in the entire carton packaging being unsightly or even unable to be sealed. In addition, the applied tape on the surface of the carton cannot be correctly aligned with the central gap formed by the carton folds. If the gap deviates too much from the center, it is easy for the carton to not be properly sealed. In addition, the existing automatic sealing device only performs sealing operations, which is not conducive to tracing the carton and its contents in the subsequent packaging process, which has a certain adverse effect on the actual use process.

[0047] The present application provides an automatic box sealing device for sealing cartons.

[0048] Figure 7 A carton 28 is shown sealed with tape 32, wherein the carton includes a top surface 30 and a bottom surface 34 and four side surfaces, wherein the top surface 30 includes a gap 33 formed by opposite flaps. The sealing of the carton 28 is to close the gap 33 with tape 32, and the tape passes from the first side surface 29 of the carton 28 through the top surface 30 to the second side surface 31. Of course, the bottom surface 34 of the carton 28 also includes a corresponding gap (not shown), and the sealing of the carton 28 also includes the use of tape 32' to close the gap on the bottom surface 34, in the same way as the sealing 33 on the top surface 30, and the tape 32' also needs to pass from the first side surface 29 of the carton 28 through the bottom surface 34 to the second side surface 31.

[0049] When packaging the carton, the carton 28 can be Figure 7 The upper and lower orientation shown is placed on the upper carton sealing device, and the upper surface 30 and the bottom surface 34 can also be placed on the corresponding side carton sealing device in a lateral orientation so that the top surface 30 and the bottom surface 34 are located at the side, and the first side surface 29 is located upstream of the second side surface. As known to those skilled in the art, the structures of the upper carton sealing device and the side carton sealing device are basically the same, and the main difference is that the orientation of the components is different. For the convenience of explanation, the automatic carton sealing device according to the present application is described in detail below using the upper carton sealing device as an example.

[0050] The automatic box sealing device according to the present application is Figure 1-5 It is shown in Figure 1 and 2 Two perspective views of the automatic box sealing device according to the present application are shown, viewed from different angles. Figure 3 , 4 5 and 5 respectively show the front view, side view and top view of the automatic carton sealing device.

[0051] See also Figure 1-5According to the present application, the automatic carton sealing device includes: a frame 25, the frame 25 may include a plurality of legs 26, the legs 26 may include wheels 27; a conveying mechanism 1, mounted and supported on the frame 25; a first frame 19, mounted across the conveying mechanism 1; a pressing mechanism 36, which is directly or indirectly mounted on the first frame 19; a box pressing member 4, connected to the pressing mechanism, capable of moving upward or downward under the drive of the pressing mechanism 36, when the box pressing member 4 moves downward, it can press the opening of the carton, that is, press the flap of the carton 28 to form the gap 33; a box sealing assembly 15, which is directly or indirectly mounted on the first frame 19, located above the conveying mechanism 1, and located downstream of the box pressing member 4, the box sealing assembly 15 is used to provide, convey and cut the tape for sealing the carton. The carton sealing assembly 15 of the automatic carton sealing device according to the present application includes a carton sealing rubber roller 16, which is used to apply tape to the carton 28. The carton sealing rubber roller 16 is directly or indirectly mounted on the first frame 19 via a spring, and its mounting position enables the carton sealing rubber roller to interfere with the carton conveyed through the carton sealing rubber roller on the conveying mechanism, and the carton sealing rubber roller 16 can press against the three surfaces of the carton 28 in sequence under the action of the spring, so that the carton sealing rubber roller 16 applies tape 32, 32' to the carton 28 under pressure.

[0052] Specifically, when the carton 28 reaches the position of the sealing rubber roller 16, the sealing rubber roller 16 first contacts the first side surface 29 of the carton 28. As the carton continues to move forward on the conveying mechanism 1, the sealing rubber roller 16 applies the adhesive tape to a portion of the first side surface 29 under a certain pressure. At the same time, the interference between the sealing rubber roller 16 and the carton overcomes the elastic force of the spring, so that the sealing rubber roller 16 gradually approaches the gap of the carton on the first side surface 29, and reaches the top surface of the carton where the gap is located, and is pressed against the top surface by the elastic force applied by the spring. As the carton continues to move forward on the conveying mechanism 1, the sealing rubber roller 16 moves along the gap, thereby applying the adhesive tape to the gap with the help of the spring at a certain pressure. When reaching the end of the gap, as the carton continues to move forward on the conveying mechanism 1, the elastic force of the spring causes the sealing rubber roller 16 to abut against the second side surface 31 of the carton and continue to apply the tape to a portion of the second side surface 31. After a predetermined length of tape is applied to the carton, the sealing assembly 15 cuts the tape.

[0053] Preferably, the pressing mechanism 36 comprises: a first driving cylinder 9, which is directly or indirectly fixed to the first frame 19; a first telescopic rod 8, which can be extended from the first driving cylinder 9 or retracted into the first driving cylinder 9; an adjusting rod seat 6, which is directly or indirectly fixed to the first frame 19; an adjusting rod 7, one end of which is pivotally connected to the adjusting rod seat 6, and the other end is pivotally connected to the end of the first telescopic rod 8, so that when the first telescopic rod 8 is extended outward from the first driving cylinder 9, the adjusting rod 7 can be moved downward around the adjusting rod seat 6 ( Figure 1 , 2 When the first telescopic rod 8 is retracted inwardly into the first driving cylinder 9, the adjusting rod 7 can be moved upward (in the clockwise direction) around the adjusting rod seat 6. Figure 1 , 2 The box-pressing member 4 is fixed to the adjusting rod 7, so when the adjusting rod is pivoted upward or downward around the adjusting rod seat 6, the box-pressing member 4 can move upward or downward.

[0054] Preferably, the automatic box sealing device according to the present application further comprises a first bracket 5, which is mounted on the first frame 19 and located above the conveying mechanism 1, and the pressing mechanism 36 is mounted on the first bracket 5. Specifically, the first driving cylinder 9 and the adjusting rod seat 6 are mounted on the first bracket 5.

[0055] Preferably, the sealing assembly 15 also includes: a tape roller 13, on which a tape is wound; a tape conveying assembly 10, including at least one roller for conveying the tape, and further conveying the tape to the sealing roller 16; a shearing mechanism (not shown), for cutting the tape, for example, when a predetermined length of tape is applied to the carton 28 by the sealing assembly 15.

[0056] Preferably, the carton sealing assembly 15 further comprises a box pressing roller 14, which is arranged upstream of the carton sealing rubber roller 16, and the box pressing roller 14 is directly or indirectly mounted on the first frame 19 through a spring. Before the carton sealing rubber roller 16 applies the adhesive tape to the carton, the box pressing roller 14 first presses the surface of the carton across the gap of the carton to prevent the flap of the carton from tilting up, thereby facilitating the carton sealing rubber roller 16 to apply the adhesive tape to the carton surface. The installation position of the box pressing roller 14 makes the box pressing roller 14 interfere with the carton 28 conveyed by the box pressing roller 14 on the conveying mechanism 1, and compared with the carton sealing rubber roller 16, the box pressing roller 14 is farther away from the corresponding surface of the carton to be sealed. Therefore, when the carton first reaches the upstream pressing roller 14 on the conveying mechanism 1, the pressing roller 14 presses the carton surface where the gap is located under the action of the spring. As the carton continues to move forward on the conveying mechanism 1, it reaches the sealing rubber roller 16, and the sealing rubber roller 16 applies the tape to the carton surface where the gap is located in the manner described above.

[0057] Preferably, see Figure 1a The box sealing rubber roller 16 and the box pressing roller 14 are installed on the second bracket 35 through a spring 39 and a connecting rod mechanism 40.

[0058] Preferably, the automatic carton sealing device according to the present application further comprises a second bracket 35, which is mounted on the first frame 19, located above the conveying mechanism 1, and located downstream of the first bracket 35, and the carton sealing assembly 15 is mounted on the second bracket 35. Specifically, the adhesive tape conveying assembly 10, the box pressing roller 14, and the carton sealing rubber roller 16 are mounted on the first bracket 5.

[0059] Preferably, the first frame 19 includes a first crossbeam 11 , the first crossbeam 11 spans across the conveying mechanism 1 , and the first bracket 5 is mounted on the first crossbeam 11 .

[0060] Preferably, the first frame 19 further includes two columns 38 connected to the first crossbeam 11. A height adjustment member 12 is disposed on the top of the column 38 for adjusting the height of the first crossbeam 11.

[0061] The automatic carton sealing device according to the present application also includes two slides 2, 2', which are arranged on the conveying mechanism 1 and are used to define the path of the carton 28 on the conveying mechanism 1 between them, so as to facilitate the alignment of the adhesive tape applied by the sealing rubber roller 16 with the gap 33 of the carton 28. The slides 2, 2' are detachably fixed to the conveying mechanism 1, for example, by bolts or screws. The slides 2, 2' include a plurality of rollers 37 and a sliding belt 3, and the sliding belt can circulate around the plurality of rollers 37. One of the two slides 2, 2' is driven by a motor and is a driving slide 2, and the other is a passive slide 2', and the linear speed of the sliding belt 3 of the driving slide 2 is the same as the linear speed of the carton 28 moving on the conveying mechanism 1.

[0062] The automatic box sealing device according to the present application further includes an electric control box 18 , which can be installed on one side of the conveying mechanism 1 and is used to control the speed of the conveying mechanism 1 and the speed of the driving slide 2 .

[0063] Furthermore, the automatic box sealing device according to the present application also includes Figure 1 and 6 The second frame 17 shown in FIG. 1 is arranged downstream of the first frame 19 .

[0064] Furthermore, the automatic carton sealing device according to the present application also includes a coding mechanism 24, which is installed on the second frame 17 and is used to code the sealed carton to facilitate the subsequent tracking of the carton and its contents.

[0065] Preferably, the coding mechanism 24 is installed on the second frame 17 through a second driving cylinder 21 and a second telescopic rod 23, and the second telescopic rod 23 can extend from or retract into the second driving cylinder 21, thereby driving the coding mechanism 24 to move up and down.

[0066] Furthermore, the automatic carton sealing device according to the present application also includes a carton sealing visual monitor 20 installed on the second frame 17 for monitoring whether the packaging of the carton 28 is qualified.

[0067] Preferably, the second frame 17 includes a second crossbeam 22 arranged across the conveying mechanism 1 , and the box sealing visual monitor 20 and the coding mechanism 24 are installed on the second crossbeam 22 .

[0068] The following describes the carton sealing process of the automatic carton sealing device according to the present application, still taking the example of a carton being transported on the conveying mechanism 1 in an up-down position.

[0069] After the carton 28 is packed, the flared opening is retracted, and the conveyor line conveys the carton to the carton sealing device for sealing with the top tape to complete the entire carton sealing work.

[0070] Specifically, the carton 28 filled with cigarettes is clamped between the sliding belts 3 of the slideways 2 and 2' on the conveying mechanism 1, and is moved from upstream to downstream ( Figure 1 When the carton 28 approaches the position below the box pressing member 4, the pressing mechanism 36 is activated, and the first drive cylinder 9 drives the first telescopic rod 8 to extend outward from the first drive cylinder 9, thereby driving the adjustment rod 7 to pivot around the adjustment seat 6 in the direction of the pointer, so that the box pressing member 4 moves downward to press the top of the carton, thereby folding the upper flap of the carton 28 to form the gap 33 ( Figure 7 ).

[0071] At the same time, as the carton continues to move downstream, the box pressing assembly 15 seals the gap 33. The adhesive tape 32 is unrolled from the adhesive tape roller 13 of the box sealing assembly 15, and is conveyed by multiple rollers of the adhesive tape conveying assembly 10 to the sealing rubber roller 16 located below the second frame 35, and is applied to the carton by the sealing rubber roller 16. After a predetermined length of the adhesive tape is unrolled, the shearing mechanism cuts the adhesive tape.

[0072] When the carton 28 reaches the position of the sealing rubber roller 16, the sealing rubber roller 16 first contacts the first side surface 29 of the carton 28. As the carton continues to move forward on the conveying mechanism 1, the sealing rubber roller 16 applies the adhesive tape to a portion of the first side surface 29 under a certain pressure. At the same time, the interference between the sealing rubber roller 16 and the carton overcomes the elastic force of the spring, so that the position of the sealing rubber roller 16 on the first side surface 29 gradually moves upward, close to the gap of the carton, and then reaches the top surface of the carton where the gap is located, and is pressed against the top surface by the elastic force applied by the spring. As the carton continues to move forward on the conveying mechanism 1, the sealing rubber roller 16 moves along the gap, thereby applying the adhesive tape to the gap 33 with a certain pressure with the help of the spring. When reaching the end of the gap, as the carton continues to move forward on the conveying mechanism 1, the elastic force of the spring causes the sealing rubber roller 16 to abut against the second side surface 31 of the carton and continue to apply the tape to a portion of the second side surface 31. After a predetermined length of tape is applied to the carton, the sealing assembly 15 cuts the tape.

[0073] The sealed carton 28 continues to move forward and reaches the second frame 17. The sealing visual monitor 20 monitors the sealing position on the top of the carton. The second driving cylinder 21 drives the second telescopic rod 23 and drives the coding mechanism 24 to code the top of the carton for easy traceability.

[0074] The entire efficient automatic carton sealing device for carton sealing has a simple structure, is easy to operate, and has a better effect than the traditional method.
