[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention allows the two second threaded rods to rotate together by rotating the handle, which in turn drives the two adjusting blocks at the outer end to move relative to each other along the upper side of the sliding plate. This, in turn, changes the distance between the two corner-sticking plates at the front and rear ends, allowing the two corner-sticking plates to be adjusted according to the width of the cardboard box on the upper side of the workbench. This enables the corner-sticking machine to perform corner-sticking work on cardboard boxes of different widths, thus improving the applicability of the corner-sticking machine.

[0017] This invention utilizes the rotating connecting ring on the outer side of the first threaded rod. When the connecting ring moves to the outer side of the first threaded rod, it can cause the side plate to slide along the inner side of the groove, thereby changing the position of the side plate on the upper part of the worktable. This allows for the restriction of cartons of different sizes and specifications between the side plates on the upper part of the worktable for corner-pressing work. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This specific embodiment is a fully automatic corner applicator, and its structural schematic diagram is as follows: Figure 1 , Figure 2 and Figure 3As shown, the device includes a workbench 1, with a fixed frame 2 welded to its rear end. A positioning mechanism is provided at the upper end of the workbench 1 and the upper end of the fixed frame 2. The positioning mechanism includes a first threaded rod 301 connected to the upper end of the workbench 1. A connecting ring 302 is connected to the outer side of the first threaded rod 301. Limiting rings 303 are fixedly connected to both ends of the outer side of the connecting ring 302. A side plate 304 is connected to the outer end of the connecting ring 302. Grooves are formed around the upper end of the workbench 1. The two ends of the first threaded rod 301 are fixedly connected to the inner ends of the grooves. The lower outer side of the side plate 304 is slidably connected to the inner side of the grooves. An internal thread is formed on the inner side of the connecting ring 302. The outer side of the first threaded rod 301 is connected to... The inner side of the connecting ring 302 is threaded, and the lower end of the side plate 304 has a round hole. The outer side of the connecting ring 302 is slidably connected to the inner side of the round hole. The two limiting rings 303 on the outer side of the connecting ring 302 are slidably connected to the lower outer side of the side plate 304. By rotating the connecting ring 302 on the outer side of the first threaded rod 301, the connecting ring 302 moves on the outer side of the first threaded rod 301, which can drive the side plate 304 to slide along the inner side of the groove, thereby changing the position of the side plate 304 on the upper end of the workbench 1. This allows different sizes of cartons to be restricted between the side plates 304 on the upper side of the workbench 1 by changing the position of each side plate 304 on the upper end of the workbench 1. A hydraulic cylinder 305 is mounted on the upper front end of the fixed frame 2. A pressure plate 306 is connected to the lower end of the output shaft of the hydraulic cylinder 305. A mounting ring 307 is fixedly connected to the middle position of the upper side of the pressure plate 306. A bolt 308 is connected inside the mounting ring 307, and a nut 309 is threaded onto the outer side of the bolt 308. A sliding hole is provided at the lower end of the output shaft of the hydraulic cylinder 305, and through holes are provided at both ends of the mounting ring 307. The outer side of the bolt 308 is slidably connected to the inner side of the sliding hole and the through hole. The upper side of the pressure plate 306... The mounting ring 307 is slid to the outer side of the lower end of the output shaft of the hydraulic cylinder 305. Then, the bolt 308 is slid into the through hole and the sliding hole. The nut 309 is then threaded onto the outer side of the bolt 308. The pressure plate 306 can then be installed at the lower end of the hydraulic cylinder 305. This disassembly and assembly method allows the pressure plate 306 at the lower end of the hydraulic cylinder 305 to be quickly disassembled and assembled. This allows for the replacement of the appropriate pressure plate 306 based on the surface area of ​​the cardboard box that needs to be fitted on the upper part of the worktable 1, thus confining the cardboard box between the worktable 1 and the pressure plate 306.

[0026] The upper end of the side panel 304 is inclined towards the four sides of the workbench 1. When the paper box is placed between the side panels 304, the inclined upper side panels 304 guide the placement of the paper box, making it easier and faster for the paper box to be placed between the side panels 304 above the workbench 1.

[0027] Cooperate Figure 4Corner-adhesive mechanisms are provided at the left and right ends above the workbench 1. Each corner-adhesive mechanism includes a base plate 401 fixedly connected to the middle position above the left and right sides of the workbench 1. A cylinder 402 is mounted on the upper side of the base plate 401. A sliding plate 403 is fixedly connected to the output shaft end of the cylinder 402. A fixed plate 404 is fixedly connected to the middle position of the upper side of the sliding plate 403. A bearing 405 is installed in the middle position inside the fixed plate 404. Second threaded rods 406 are symmetrically installed at the front and rear ends of the inner side of the bearing 405. The second threaded rods 406 are located away from the shaft. A rotating handle 407 is welded to one end of the bearing 405. An adjusting block 408 is connected to the outer end of the second threaded rod 406. A corner plate 409 is welded to the outer side of the adjusting block 408. The inner side of the corner plate 409 abuts against the four outer corners of the paper box at the upper end of the workbench 1. By starting the cylinder 402, its output shaft extends and drives the sliding plate 403 to slide along the upper side of the workbench 1. This can move the corner plate 409 to the four outer corners of the paper box at the upper end of the workbench 1 to flatten and correct the four corners of the paper box, thus solving problems such as bubbles, bulging, wrinkles, and deformation at the four corners of the paper box.

[0028] The lower side of the sliding plate 403 is slidably connected to the upper side of the workbench 1. The adjusting block 408 has a threaded hole that runs through it. The outer side of the second threaded rod 406 is threadedly connected to the inner side of the threaded hole. The lower side of the adjusting block 408 is slidably connected to the upper side of the sliding plate 403. By rotating the rotating handle 407, the two second threaded rods 406 rotate together, which can drive the two adjusting blocks 408 at the outer end to move relative to each other along the upper side of the sliding plate 403. This, in turn, changes the distance between the two corner-sticking plates 409 at the front and rear ends, so that the two corner-sticking plates 409 can be adjusted according to the width of the cardboard box on the upper side of the workbench 1. This allows the corner-sticking machine to perform corner-sticking work on cardboard boxes of different widths, thus improving the application range of the corner-sticking machine.

[0029] Working principle: When performing corner pasting on a carton, first rotate the connecting ring 302 to move the side plates 304 above the workbench 1 to a suitable distance to limit the corners of the carton to be pasted. Then, slide the mounting ring 307 on the upper side of the pressure plate 306 of the required size to the outer side of the lower end of the output shaft of the hydraulic cylinder 305. Then, fix it by bolts 308 passing through the through hole and the sliding hole. Next, rotate the mounting ring 307 to rotate the two second threaded rods 406, which will drive the corner pasting plates 409 at the front and rear ends to move relative to each other until the corner pasting plates 409 at the front and rear ends move to a suitable distance to paste the four corners of the carton. When applying corner plaster, stop rotating the handle 407. Then place the cardboard box between the side plates 304 on the upper side of the workbench 1. Next, start the hydraulic cylinder 305 to move the pressure plate 306 to the upper side of the cardboard box, confining the cardboard box between the workbench 1, the pressure plate 306, and the side plates 304 to ensure the cardboard box is fixed during corner plastering. Finally, start the cylinder 402 to slide along the upper side of the workbench 1 until it moves the corner plastering plate 409 to the four outer corners of the cardboard box, flattening and correcting the four corners of the cardboard box to solve problems such as air bubbles, bulging, wrinkles, and deformation at the four corners of the cardboard box.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
