The appearance of paper box packaging has a great impact on the sales of commodities, such as alcohol, tea, gifts, etc. This type of packaging box generally needs to be pasted with a layer of bright-looking wrapping paper on the outside of the paper box. In the prior art, the packaging box is generally folded into a square tube, and then the bottom is sealed. The wrapping paper needs to be folded inward into the inner side of the paper box at the box mouth to cover the three sides of the box mouth. When the paper box is sealed at the bottom and the box mouth is hemmed, in order to ensure the effect, the paper box needs to be clamped to prevent the paper box from shaking. At present, in order to avoid the shaking of the paper box in the prior art, one side of the paper box is generally clamped, resulting in poor clamping effect.

[0060] See also Figures 1 to 4 , the paper box edge wrapping and bottom sealing device 100 provided in the present application is now described. The paper box edge wrapping and bottom sealing device 100 is used to fold the box mouth of the paper box 101 and seal the bottom 104 of the paper box 101. The paper box 101 includes a box body 102, a box mouth 103 and a bottom 104. A wrapping paper 105 is pasted on the outside of the paper box 101. It can be understood that the paper box 101 in the present application is mainly a packaging box for goods. In order to ensure the beauty of the paper box 101 and to promote the goods, a layer of wrapping paper 105 is generally pasted on the packaging box of the goods. During the processing of the paper box 101, the wrapping paper 105 will be pasted first and then folded into a square tube. Finally, the bottom 104 of the paper box 101 will be sealed, and the wrapping paper 105 at the box mouth of the paper box 101 will be folded to the inside of the box mouth to wrap the box mouth. For specific edge wrapping and bottom sealing states, please refer to the attached Figure 1 . The "outside" of the paper box 101 mentioned in the present application refers to the outermost part used for display when the paper box 101 is used to package goods, and the "inside" of the paper box 101 refers to the part hidden inside the paper box 101 when the goods are packaged, and can only be viewed by opening the paper box 101. In other words, the paper box edge-wrapping and bottom-sealing device 100 of the present application is to seal the bottom 104 of the paper box 101 to which the wrapping paper 105 has been affixed, and to perform edge-wrapping on the box mouth of the paper box 101. For the convenience of description, the square cylindrical part of the paper box 101 is referred to as the box body 102, a side surface at the box mouth of the paper box 101 and three side ears connected to the side surface are referred to as the box mouth 103, and the bottom 104 of the paper box 101 is referred to as the bottom 104.

[0061] The paper box hemming and bottom sealing device 100 includes a machine platform 10, a limiting mechanism 20, a first abutting mechanism 30 and a second abutting mechanism 40. The machine platform 10 is used to carry the paper box 101 and drive the paper box 101 to move. The limiting mechanism 20 is used to prevent the paper box 101 from continuing to move forward and adjust the position of the paper box 101. The first abutting mechanism 30 is used to abut one side of the box body 102 of the paper box 101 after the paper box 101 stops moving, and push the paper box 101 against the machine platform 10. The second abutting mechanism 40 is connected to the first abutting mechanism 30. The second abutting mechanism 40 is used to abut the other side of the box body 102 of the carton 101 after the carton 101 abuts against the machine 10. The second abutting mechanism 40 drives the first abutting mechanism 30 to work simultaneously. The limiting mechanism 20, the first abutting mechanism 30 and the second abutting mechanism 40 are all arranged on the machine 10. That is to say, when the carton 101 is transferred to the machine 10, the machine 10 will continue to move forward with the carton 101. When the carton 101 moves close to the target position, the machine 10 will stop working, and the carton 101 will also stop working. Due to inertia, the paper box 101 may continue to move forward, or, when a malfunction or error occurs during the operation of the machine 10, the paper box 101 may not stop at the target position, but may continue to move forward. At this time, the limiting mechanism 20 will prevent the paper box 101 from continuing to move forward and push the paper box 101 back to the target position. At the same time, the limiting mechanism 20 can also prevent the paper box 101 from continuing to slide forward due to inertia. After the paper box 101 stops moving, the second abutting mechanism 40 drives the first abutting mechanism 30 to move toward the paper box 101 at the same time. The abutting mechanism 30 first abuts against one side of the body 102 of the paper box 101 and pushes the paper box 101 against the machine 10 to prevent the paper box 101 from shaking. Then the second abutting mechanism 40 abuts against the other side of the body 102 of the paper box 101 to further limit the position of the paper box 101. The first abutting mechanism 30, the second abutting mechanism 40 and the machine 10 simultaneously limit the four sides of the body 102 of the paper box 101, so as to better fix the position of the paper box 101 and reduce the error when the box mouth 101 is hemmed and the bottom is sealed.In the embodiment of the present application, the limiting mechanism 20 is first used to block the paper box 101 from continuing to move forward, and the paper box 101 is pushed back to the target position, and then the first abutting mechanism 30 abuts one side of the box body 102 and pushes the paper box 101 against the machine table 10, and the second abutting mechanism 40 abuts the other side of the box body 102, so that the first abutting mechanism 30, the second abutting mechanism 40 and the machine table 10 respectively abut the four sides of the box body 102 of the paper box 101 to clamp the paper box 101 and reduce the shaking of the paper box 101, so as to reduce the error when the paper box 101 is sealed at the bottom and the box mouth is folded; and the second abutting mechanism 40 is used to drive the first abutting mechanism 30 to work, and only the second abutting mechanism 40 needs to be operated to drive the first abutting mechanism 30 to move, and only one driving member is required to clamp the paper box 101, thereby reducing the setting of the driving member, making the equipment simpler and lighter, more convenient to operate, and also reducing the production cost.

[0062] Compared with the prior art, the paper box edge wrapping and bottom sealing device 100 provided in the present application first blocks the paper box 101 from moving forward through the limiting mechanism 20, and pushes the paper box 101 back to the target position, and then abuts one side of the box body 102 through the first abutting mechanism 30, and pushes the paper box 101 against the machine 10, and abuts the other side of the box body 102 through the second abutting mechanism 40, so that the first abutting mechanism 30, the second abutting mechanism 40 and the machine 10 The four sides of the box body 102 of the paper box 101 are respectively abutted to clamp the paper box 101, thereby reducing the shaking of the paper box 101 and reducing the error when the bottom of the paper box 101 is sealed and the box mouth is folded; and the second abutting mechanism 40 is used to drive the first abutting mechanism 30 to work, and the first abutting mechanism 30 can be driven to move by operating the second abutting mechanism 40. Only one driving member is needed to clamp the paper box 101, which reduces the setting of the driving member, makes the equipment simpler and lighter, and is more convenient to operate, while also reducing the production cost.

[0063] In one embodiment, see Figures 3 to 5 An edge 14 is provided on the platform 10 at a position opposite to the first abutting mechanism 30, so that when the first abutting mechanism 30 pushes the paper box 101 against the platform 10, the first abutting mechanism 30 and the edge 14 jointly abut the two sides of the paper box 101, so that the paper box 101 abuts more stably.

[0064] In one embodiment, see Figures 3 to 5 The first abutting mechanism 30 and the second abutting mechanism 40 respectively abut two adjacent sides of the body 102 of the paper box 101, and the machine 10 abuts the other two adjacent sides of the body 102 of the paper box 101, so that the first abutting mechanism 30, the second abutting mechanism 40 and the machine 10 can respectively abut the four sides of the body 102 of the paper box 101, thereby clamping the paper box 101.

[0065] In one embodiment, see Figures 3 to 5 A position sensor 80 is provided on the machine 10 to transport the paper box 101 to the target position. When the paper box 101 is transported to the vicinity of the target position, the position sensor 80 sends a signal to the machine 10 to stop the movement of the machine 10, thereby better controlling the position of the paper box 101 during the edge wrapping and bottom sealing.

[0066] In one embodiment, see Figures 4 to 6 The first abutment mechanism 30 includes a first abutment plate 31 and a transmission member 32. The transmission member 32 is used to drive the first abutment plate 31 to move toward or away from the box body 102 of the paper box 101. The transmission member 32 is connected to the second abutment mechanism 40. That is to say, when the second abutment mechanism 40 is working, the power is transmitted to the first abutment plate 31 through the transmission member 32, so that the first abutment plate 31 pushes the paper box 101 to press against the machine 10.

[0067] In one embodiment, see Figures 4 to 6 The transmission member 32 includes an inclined plate 321, a roller 322, a first fixed plate 323, a first linear motion mechanism 324, a connecting rope 325 and a connecting block 326. The inclined plate 321 is installed on the machine 10. The side of the inclined plate 321 facing the paper box 101 is provided with a first inclined surface 3211. The lower side of the first inclined surface 3211 is inclined toward the side of the box body 102 corresponding to the first abutting mechanism 30, that is, the width of the end of the inclined plate 321 close to the paper box 101 is wider than the end away from the paper box 101. The roller 322 is arranged on the second abutting mechanism. The roller 322 moves back and forth on the first inclined surface 3211. The first fixed plate 323 is fixed on the machine 10. The first linear motion mechanism 324 The linear moving mechanism 324 is installed on the first fixed plate 323, one end of the connecting rope 325 is connected to the first abutting plate 31, the connecting block 326 is slidably installed on the first linear moving mechanism 324, and the two ends of the connecting block 326 are respectively connected to the roller 322 and the other end of the connecting rope 325, that is, the transmission member 32 is an inclined wedge mechanism. When the second abutting mechanism 40 works, it drives the transmission member 32 to work together, and the roller 322 rolls back and forth on the first inclined surface 3211, driving the connecting block 326 and the connecting rope 325 to pull the first abutting plate 31 closer to or away from the box body 102 of the paper box 101. Using the inclined wedge mechanism as the transmission member 32 is simple to set up and has high accuracy. In order to ensure the connection strength, the connecting rope 325 can be a steel wire rope (attached Figure 3-6 Only a part of the connecting rope 325 is shown in the figure) or other connecting ropes 325 with higher strength. In some embodiments, the transmission member 32 can also be a transmission method such as gear transmission, belt transmission, screw transmission, etc.

[0068] In one embodiment, see Figure 3 and Figure 4 The second abutting mechanism 40 includes a first abutting assembly 41, a support plate 42, a second linear motion mechanism 43 and a first driving member 44. The first abutting assembly 41 is used to abut the other side of the box body 102 of the paper box 101. The support plate 42 is used to support the first abutting assembly 41. The first linear motion mechanism 324 is used to connect the machine 10 and the support plate 42. The first driving member 44 is used to drive the support plate 42 to move in a direction close to or away from the box body 102 of the paper box 101. The first abutting mechanism 30 is connected to the support plate 42, that is to say. The first driving assembly drives the support plate 42 to move, and the support plate 42 then drives the first abutting assembly 41 to move in a direction close to or away from the box body 102 of the paper box 101, so as to abut against the side of the box body 102 of the paper box 101 or away from the paper box 101, and the movement of the support plate 42 drives the second abutting mechanism 40 to work at the same time. This arrangement makes the structure of the first abutting mechanism 30 simple and easy to operate.

[0069] In one embodiment, see Figure 3 and Figure 4 The first abutting assembly 41 includes a fixed block 411, a third abutting plate 412, a second connecting shaft 413 and a second elastic member 414. The fixed block 411 is mounted on the supporting plate 42. The third abutting plate 412 is used to abut the other side of the box body 102 of the paper box 101. The second connecting shaft 413 connects the fixed block 411 and the third abutting plate 412. The second elastic member 414 is sleeved on the second connecting shaft 413. That is, after the first abutting assembly 41 abuts the other side of the box body 102 of the paper box 101, the second elastic member 414 can prevent the first abutting assembly 41 from applying a large force to the paper box 101, thereby causing the paper box 101 to be compressed and deformed. The second elastic member 414 can be a spring, soft rubber or other components with large elasticity that can play a buffering role.

[0070] In one embodiment, see Figures 3 to 5The paper box edge wrapping and bottom sealing device 100 also includes a third abutting mechanism 50 , which is used to abut against the box mouth 103 of the paper box 101 , and the third abutting mechanism 50 is arranged on the second abutting mechanism 40 . The third abutment mechanism 50 includes a second abutment plate 51, a connecting plate 52, a first connecting shaft 53 and a first elastic member 54. The second abutment plate 51 is used to abut the inner side of the box mouth 103. The connecting plate 52 is installed on the second abutment mechanism 40. The first connecting shaft 53 is used to connect the connecting plate 52 and the second abutment plate 51. The first elastic member 54 is placed on the first connecting shaft 53. That is, when the second abutment mechanism 40 moves toward the box body 102 of the paper box 101, it also drives the second abutment plate 51 of the third abutment mechanism 50 to move toward the box mouth 103 of the paper box 101 and abut against the inner side of the box mouth 103 to further clamp the box mouth 103 of the paper box 101 to avoid the box mouth 103 from moving when the box mouth of the paper box 101 is folded. The first elastic member 54 can provide a buffering effect when the second abutment plate 51 applies too much force to the box mouth 103. By arranging the third abutting mechanism 50 on the second abutting mechanism 40, the second abutting mechanism 40 can drive the first abutting mechanism 30 and the third abutting mechanism 50 to work at the same time when working, which further improves the convenience of use and reduces the operation steps. The first elastic member 54 can be a spring, soft rubber or other components with large elasticity that can play a buffering role.

[0071] In one embodiment, a sponge or other softer component may be provided on the side of the first abutting plate 31 , the second abutting plate 51 and the third abutting plate 412 facing the paper box 101 to further provide a buffer for the paper box 101 and prevent the paper box 101 from being deformed due to a large force.

[0072] In one embodiment, see Figure 3 and Figure 4 The limiting mechanism 20 includes a baffle 21, a second driving member 22, a second fixed plate 23 and a third linear motion mechanism 24. The second driving member 22 is used to drive the baffle 21 to block the paper box 101 from moving forward. The second fixed plate 23 is used to install the second driving member 22. The third linear motion mechanism 24 connects the second fixed plate 23 and the machine 10. That is to say, when the paper box 101 moves to the target position, the second driving member 22 drives the baffle 21 to move toward the direction of the paper box 101 and blocks the paper box 101 from continuing to move forward due to inertia or equipment failure. Moreover, after blocking the paper box 101 from moving forward, the baffle 21 can push the paper box 101 back to the target position through the third linear motion mechanism 24. The operation is simple and convenient, and the position of the paper box 101 can be better adjusted to avoid errors when the paper box 101 is hemmed and sealed.

[0073] In one embodiment, see Figure 3 and Figure 4The paper box edge wrapping and bottom sealing device 100 includes a folding mechanism 60 and a bottom sealing mechanism 70. The folding mechanism 60 is used to fold the wrapping paper 105 toward the inner side of the box mouth 103, and the bottom sealing mechanism 70 is used to seal the bottom 104 of the paper box 101. The folding mechanism 60 and the bottom sealing mechanism 70 are both arranged on the machine 10 and are respectively located on opposite sides of the machine 10. It can be understood that the folding mechanism 60 acts on the box mouth 103 of the paper box 101 to fold the wrapping paper 105 at the box mouth 103 of the paper box 101 toward the inner side of the box mouth 103 for edge wrapping, and the bottom sealing mechanism 70 acts on the bottom 104 of the paper box 101 to close the bottom 104 of the paper box 101 to form a tubular structure with only the box mouth open.

[0074] In one embodiment, see Figure 3 , Figure 4 and Figure 7 The folding mechanism 60 includes three folding components 61, a mounting platform 62, a third driving member 63 and a fourth linear motion mechanism 64. The three folding components 61 are respectively arranged corresponding to the three side edges of the box mouth 103 of the paper box 101, and are used to fold the packaging paper 105 at the corresponding side edges toward the inner side of the box mouth 103. The mounting platform 62 is used to install the three folding components 61, and the third driving member 63 is used to drive the mounting platform 62 to move toward or away from the box mouth 103. The third linear motion mechanism 24 connects the mounting platform 62 and the machine 10. That is to say, the three folding mechanisms 60 can be driven to rise and fall at the same time through the third driving member 63, and the operation is simple and convenient.

[0075] In one embodiment, see Figure 7The folding assembly 61 includes an inclined platform 611, a fourth driving member 612 and a folding block 613. The inclined platform 611 is arranged on the mounting platform 62. The side of the inclined platform 611 facing the box mouth 103 has a second inclined surface 6112. The second inclined surface 6112 is inclined downward from the side away from the bottom cover mechanism 70 to the side close to the bottom cover mechanism 70. The fourth driving member 612 is installed on the second inclined surface 6112. The folding block 613 is used to fold the packaging paper 105 to the inner side of the corresponding box mouth 103 side. The folding block 613 is slidably connected to the third linear moving mechanism 24, that is, the fourth driving member 612 and the folding block 613 are both installed obliquely. When the paper box 101 is placed on the machine 10, the box mouth of the paper box 101 When the portion 103 is placed correspondingly at the folding mechanism 60, the entire mounting platform 62 is first driven by the fourth driving member 612 to move toward the paper box 101, and the height of the folding block 613 is made higher than the height of one side of the paper box 101 contacting the machine platform 10. At this time, the folding block 613 lifts the packaging paper 105 to a position higher than the box mouth 103, and then drives the fourth driving member 612 to move toward the direction close to the bottom sealing mechanism 70. Since the fourth driving member 612 is obliquely installed on the oblique platform 611, the fourth driving member 612 drives the folding block 613 to move toward the inside of the box mouth 103 and downward when working, so that the folding block 613 drives the packaging paper 105 to stick to the inside of the box mouth 103, thereby realizing the edging of the box mouth 103. By obliquely installing the fourth driving member 612 and the folding block 613 on the mounting platform 62, only one action is required to move the folding block 613 obliquely downward, thereby driving the packaging paper 105 to stick to the inner side of the box mouth 103, and the operation is simple and convenient.

[0076] In one embodiment, see Figure 3 and Figure 7 A flat plate 15 is provided on the machine 10 at a position corresponding to the opening 103 of the paper box 101. When the paper box 101 moves to the target position, the opening 103 of the paper box 101 is just located on the flat plate 15 to facilitate the folding of the folding mechanism 60.

[0077] In one embodiment, see Figure 3 , Figure 4 and Figure 8 The bottom sealing mechanism 70 includes a roller 71, a fifth driving member 72, a mounting plate 73 and a fifth linear motion mechanism 74. The roller 71 is used to push the bottom 104 of the paper box 101 to seal the box body 102. The fifth driving member 72 is used to drive the roller 71 to roll. The mounting plate 73 is fixed on the machine 10. The fifth linear motion mechanism 74 connects the mounting plate 73 and the roller 71. The fifth driving member 72 is installed on the mounting plate 73. That is, the fifth driving member 72 drives the roller 71 to move upward to drive the bottom 104 of the paper box 101 to move upward and seal the box body 102, thereby achieving the bottom sealing of the paper box 101.

[0078] In one embodiment, see Figures 3 to 5 The machine 10 includes a frame 11, a conveyor belt 12 and a driving mechanism 13. The conveyor belt 12 is arranged on the frame 11. The driving mechanism 13 drives the conveyor belt 12 to move. When the paper box 101 is transferred to the machine 10, the paper box 101 is located on the conveyor belt 12. The driving mechanism 13 drives the conveyor belt 12 to move, and then transfers the paper box 101 to the target position. In some embodiments, the driving mechanism 13 can be a combination of a motor and a pulley, or a combination of a motor and a screw, or other combinations that can drive the conveyor belt 12 to transmit.

[0079] In one embodiment, the first driving member 44, the second driving member 22, the third driving member 63, the fourth driving member 612 and the fifth driving member 72 can be driving members of motors, cylinders, etc., or can be a driving structure composed of motors, cylinders and other components.

[0080] In one embodiment, the first linear motion mechanism 324, the second linear motion mechanism 43, the third linear motion mechanism 24, the fourth linear motion mechanism 64 and the fifth linear motion mechanism 74 can be linear motion modules combining a slide table and a slide rail, or can be linear motion mechanisms such as belts, screws, and gears.

[0081] See also Figure 1 Another object of the embodiment of the present application is to provide a carton forming device 1000, including a transmission device 200 and a carton edge wrapping and bottom sealing device 100 of any of the above embodiments, and the transmission device 200 transmits the carton 101 to the machine platform 10. By using the above-mentioned paper box edge wrapping and bottom sealing device 100, the paper box 101 is first blocked from moving forward by the limiting mechanism 20, and the paper box 101 is pushed back to the target position, and then the first abutting mechanism 30 abuts one side of the box body 102, and the paper box 101 is pushed against the machine table 10, and the second abutting mechanism 40 abuts the other side of the box body 102, so that the first abutting mechanism 30, the second abutting mechanism 40 and the machine table 10 respectively abut the four sides of the box body 102 of the paper box 101 to clamp the paper box 101, reduce the shaking of the paper box 101, and reduce the error when the paper box 101 is sealed and the box mouth is folded; and the second abutting mechanism 40 is used to drive the first abutting mechanism 30 to work, and only the second abutting mechanism 40 is operated to drive the first abutting mechanism 30 to move, and only one driving member is required, which reduces the setting of the driving member, makes the equipment simpler and lighter, and more convenient to operate, and also reduces the production cost.

[0082] The above description is only an optional embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
