Detailed Implementation

[0024] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. After reading the present invention, any modifications of the present invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0025] like Figures 1-5 As shown, a conveying device for sealing the top cover of a carton includes a belt conveyor 1 and a support column 2. The support column 2 is fixedly connected to the lower end of the belt conveyor 1, and a limiting mechanism is provided at the upper end of the belt conveyor 1.

[0026] The limiting mechanism includes a linear motor 301 installed at the rear end of the belt conveyor 1. A connecting rod 302 is installed at the front end of the linear motor 301. A round shaft 303 is fixedly connected at equal intervals to the front side of the connecting rod 302. A baffle 304 is fixedly connected to the front end of the round shaft 303. A pressure roller 305 is connected to the outer end of the round shaft 303. A rotating hole is opened inside the pressure roller 305. The outer side of the round shaft 303 is rotatably connected to the inner side of the rotating hole. The rear side of the pressure roller 305 is slidably connected to the front side of the connecting rod 302. The front side of the pressure roller 305 is slidably connected to the rear side of the baffle 304. Thus, when the pressure roller 305 rotates outside the round shaft 303, it can only rotate between the connecting rod 302 and the baffle 304.

[0027] A tape-sealing device 306 is installed at the left end of the connecting rod 302. The outer side of the pressure roller 305 is rolled to the upper side of the carton lid. After the carton with the lid folded down by the worker is placed on the upper right side of the belt conveyor 1, the carton lid, which is being conveyed on the belt conveyor 1, will always be in contact with the outer side of the pressure roller 305, keeping it in a folded state until it moves to the tape-sealing device 306 at the left end and is sealed with tape. Thus, through the limiting mechanism on the conveying device, as long as the carton lid is folded to the top of the carton when it is placed on the belt conveyor 1, it can remain folded during the conveying process. This allows the sealing conveyor to ignore the tilt of the carton lid in its natural state and seal different types of cartons.

[0028] The left and right ends of the lower side of the connecting rod 302 are provided with telescopic rods 307, and the lower ends of the telescopic rods 307 are fixedly connected to the upper side of the rear end of the belt conveyor 1, so that when the linear motor 301 drives the connecting rod 302 to move, the telescopic rods 307 at the left and right ends of the lower side of the connecting rod 302 will keep synchronous telescopic, so as to ensure that the connecting rod 302 as a whole keeps stable translation, avoiding shaking of the connecting rod 302 during movement to affect the normal work of the linear motor 301.

[0029] The upper end of the belt conveyor 1 is provided with an adjusting mechanism, which comprises a rear fixed plate 401 fixedly connected to the upper right side of the rear end of the belt conveyor 1, a front fixed plate 402 fixedly connected to the upper right side of the front end of the belt conveyor 1, a bearing 403 fixedly connected to the inner middle position of the rear fixed plate 401, a first threaded rod 404 fixedly connected to the inner side of the bearing 403, a second threaded rod 405 fixedly connected to the front end of the first threaded rod 404 in a symmetrical manner, a rotating handle 406 fixedly connected to the front end of the second threaded rod 405, and a through hole formed in the inner middle position of the front fixed plate 402, and the front end of the second threaded rod 405 is rotatably connected to the inner side of the through hole, so that when the rotating handle 406 is rotated, the second threaded rod 405 and the first threaded rod 404 can be kept horizontally rotated.

[0030] The outer ends of the first threaded rod 404 and the second threaded rod 405 are connected to limit plates 407, the upper sides of the rear fixed plate 401 and the front fixed plate 402 are fixedly connected to a top plate 408, a threaded hole is formed in the inner right end of the limit plate 407, the outer sides of the first threaded rod 404 and the second threaded rod 405 are screw-connected to the inner sides of the threaded hole, the lower side of the limit plate 407 is slidably connected to the upper side of the belt conveyor 1, and the upper right end of the limit plate 407 is slidably connected to the lower side of the top plate 408, so that when the rotating handle 406 is rotated to make the second threaded rod 405 and the first threaded rod 404 rotate together, the two limit plates 407 at the outer ends can be relatively moved along the upper side of the belt conveyor 1, so that the distance between the two limit plates 407 can be adjusted to the same width of the carton to be conveyed according to the width of the carton to be conveyed on the upper side of the belt conveyor 1, so as to ensure that the carton on the belt conveyor 1 is smoothly conveyed to below the adhesive tape device 306, thereby ensuring the accuracy of the adhesive tape sticking position during sealing of the carton, and through adjustment of the distance between the two limit plates 407, the carton of different widths on the belt conveyor 1 can be limited, thereby enhancing the use range of the transmission device.

[0031] As Figures 1-5As shown, the working principle of the transmission device for carton top sealing is as follows: when the carton is transmitted and sealed, first rotate the rotary handle 406 to drive the first threaded rod 404 and the second threaded rod 405 to rotate together until the two limiting plates 407 at the outer end move to the same width as the width of the carton to be conveyed, then start the linear motor 301 to drive the connecting rod 302 to move until the pressing roller 305 moves to the bottom end and the interval between the upper side of the belt conveyor 1 is located at the height of the carton, then start the belt conveyor 1, then the staff folds and presses down the carton cover, and then places it on the right side of the upper side of the belt conveyor 1, the carton conveyed to the left directly contacts the outer lower end of the pressing roller 305, keeps the folded state, until it moves to the lower side of the adhesive tape device 306, is sealed by the adhesive tape, and then continues to move to the left and is taken off.
