Obviously, the embodiments described 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 efforts are within the scope of protection of the present invention.

[0024] See also Figure 1 、 Figure 2 as well as Figure 4The embodiment proposes a gluing machine with a positioning function for cartons, comprising a conveying seat 1, the top two ends of the conveying seat 1 are rotatably connected with a transmission wheel 2 for transmission, the outer side of the transmission wheel 2 is provided with a conveyor belt 21 for conveying cartons, the top of the conveyor belt 21 is provided with a limiting plate 3 for positioning the length of the carton, the outer side of the limiting plate 3 is fixedly installed with a positioning sensor 31 for positioning the length of the carton, the outer side of the limiting plate 3 is fixedly installed with an outer box 4, the inner side wall of the outer box 4 is slidably connected with a positioning component 5 for positioning the carton passing, and the inner side wall of the outer box 4 is also slidably connected with a positioning sensor for the carton The gluing component 6 for gluing at the end, the inner side wall of the outer box 4 is provided with a driving component 7 for driving the positioning component 5 and the gluing component 6, and a mounting plate 8 for installation is slidably connected to one side of the top of the conveying seat 1. The mounting plate 8 can disassemble the entire structure from the conveying seat 1, which is more convenient for the installation and disassembly of the entire structure. Two electric telescopic rods 81 for driving the limit plate 3 to slide are fixedly installed on one side of the mounting plate 8. The telescopic ends of the two electric telescopic rods 81 are fixedly connected to the inner side of the limit plate 3, and the outer side of the conveying seat 1 is fixedly installed with a main motor 22 for driving the transmission wheel 2 to rotate. The output end of the main motor 22 is fixedly connected to one end of the transmission wheel 2. When the glue machine is used to glue the end of the carton, the transmission wheel 2 can be driven by the main motor 22 to rotate on the conveying seat 1, thereby driving the conveyor belt 21 to drive through the conveyor wheel, so that the conveyor belt 21 can drive the carton to be transported. While the carton is being transported on the conveyor belt 21, the front end of the limit plate 3 can be used to guide one end of the carton to fit with the conveying seat 1, and the other end can be driven by the electric telescopic rod 81 to fit the end of the carton. When the carton continues to be transmitted to the position of the outer box 4, the positioning component 5 can be contacted with the carton to make the positioning component 5 slide toward the inside of the outer box 4, and provide feedback to the driving component 7, so that the driving component 7 can drive the gluing component 6 to slide downward by an equal distance, so that after the carton passes the position of the positioning component 5, the gluing component 6 contacts the carton at the same time and starts to gluing the edge of the carton. After the gluing of the carton is completed and the positioning component 5 is separated, the gluing component 6 and the positioning component 5 slide to the initial position inside the outer box 4, and the gluing component 6 can be closed, thereby improving the convenience of the gluing operation on the carton.

[0025] See also Figure 3 、 Figure 4 as well as Figure 5The present embodiment proposes a glue machine with a positioning function for a carton. The positioning assembly 5 includes a positioning block 51 slidably connected to the inner wall of the outer box 4. An active gear rod 52 is fixedly installed on the top of the positioning block 51. The positioning assembly 5 also includes a pressing block 53 fixedly installed on the outside of the active gear rod 52. An auxiliary button 54 is fixedly installed on the inner wall of the outer box 4. When the carton moves to the position of the positioning block 51, the positioning block 51 is pushed upward by the carton, so that the active gear rod 52 slides upward inside the outer box 4, driving the pressing block 53 to press the auxiliary button 54. The gluing assembly 6 includes an outer frame 61 slidably connected to the inner wall of the outer box 4. A driven gear rod 62 is fixedly installed on the top of the outer frame 61. The inner wall of the outer frame 61 is rotatably connected to the gluing column 63. The glue assembly 6 also includes a first delivery pipe 64 fixedly installed on the outside of the outer frame 61, and the bottom end of the first delivery pipe 64 is connected to the second delivery pipe 65. The outer side of the second delivery pipe 65 is rotatably connected to the inner side wall of the glue coating column 63. The glue coating assembly 6 also includes a glue storage box 66 fixedly installed on the top inner wall of the outer box 4. The bottom end of the glue storage box 66 and the top of the first delivery pipe 64 are provided with delivery holes 67. The top of the glue storage box 66 is connected to a telescopic tube 68. When the positioning block 51 drives the active gear rod 52 to slide upward, the driven gear rod 62 drives the outer frame 61 to slide downward to the outside of the outer box 4, so that the outer side of the glue coating column 63 fits with the carton, and at this time the outer frame 61 synchronously drives the first delivery pipe 64 to slide downward, so that the delivery hole 67 on the first delivery pipe 64 is in contact with the outer box 4. The delivery holes 67 on the glue storage box 66 are connected, so that the glue inside the glue storage box 66 can flow to the inside of the second delivery pipe 65 through the first delivery pipe 64. Since the glue coating column 63 can rotate inside the outer frame 61 and outside the second delivery pipe 65, the second delivery pipe 65 can flow the glue to the inside of the glue coating column 63, so that the glue coating column 63 can perform the gluing operation by contacting and rotating with the carton. The glue inside the glue storage box 66 can be added and connected through the telescopic tube 68. When the carton is gluing and disengaged from the positioning block 51, the outer frame 61 moves upward to its initial position, and the outer frame 61 drives the first delivery pipe 64 to slide inside the glue storage box 66, so that the first delivery pipe 64 and the delivery hole 67 on the glue storage box 66 are staggered, and then the glue in the glue storage box 66 can be added. The conveying is closed, and the driving assembly 7 includes a driving rod 71 rotatably connected to the inner wall of the outer box 4. A driving gear 72 is fixedly installed on the outer side of the driving rod 71. The driving gear 72 is meshed with the active gear rod 52 and the driven gear rod 62 respectively. The driving assembly 7 also includes a driving motor 73 fixedly installed on the inner wall of the outer box 4. The output end of the driving motor 73 is fixedly connected to one end of the driving rod 71. When the positioning block 51 slides to press the auxiliary button 54, the driving motor 73 can be controlled by the auxiliary button 54 to start, so that the driving motor 73 can drive the driving gear 72 on the driving rod 71 to rotate, thereby causing the active gear rod 52 and the driven gear rod 62 to slide in opposite directions relative to each other, so that when the positioning block 51 slides upward, the glue coating column 63 slides downward to glue the passing carton.When the positioning block 51 slides downward, the glue-spreading column 63 slides upward to close the glue supply to the glue storage box 66.

[0026] In this embodiment, when in use, the carton is first conveyed by the conveyor belt 21, and the carton is guided by the limit plate 3, so that the end of the carton is fitted with the conveying seat 1, and the other end is fitted with the limit plate 3, and the positioning sensor 31 provided on the limit plate 3 can sense the width of the carton so that the limit plate 3 can be driven by the electric telescopic rod 81 so that the outer side of the limit plate 3 is fitted with the other end position of the carton. When the carton passes the position of the outer box 4, the positioning block 51 can be pushed upward by the carton, so that the pressing block 53 can press the auxiliary button 54, and the auxiliary button 54 provides feedback to start the drive motor 73 to drive the drive rod 71 to rotate inside the outer box 4, so that the drive gear 72 on the drive rod 71 can drive The outer frame 61 moves downward, and the gluing column 63 is fitted with the other end of the carton, and the first conveying pipe 64 is relatively connected to the conveying hole 67 of the glue storage box 66, so that the glue inside the glue storage box 66 can flow through the first conveying pipe 64 and the second conveying pipe 65 to the inside of the gluing column 63 for fitting and gluing the carton. After the gluing of the carton is completed, the positioning block 51 and the gluing column 63 move to the initial position, and the first conveying pipe 64 follows the outer frame 61 to move to the initial position, and the first conveying pipe 64 and the conveying hole 67 of the glue storage box 66 are staggered and closed, and the gluing operation of the gluing column 63 is stopped, thereby solving the problems of not being able to adjust the gluing position according to the width of the carton and not being able to open or close the gluing according to whether there is a carton passing through.
