DETAILED DESCRIPTION

[0047] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the following will be further detailed in combination with specific embodiments.

[0048] It should be noted that, unless otherwise defined, technical terms or scientific terms used in the present application should be understood as the common meaning understood by those skilled in the art to which the present application belongs. The "first", "second" and similar words used in the present application do not represent any order, quantity or importance, but are only used to distinguish different components.

"Connected" or "connected" and similar words are not limited to physical or mechanical connection, but can include electrical connection, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to represent the relative positional relationship, when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0049] As shown in Figure 1 , Figure 2 and Figure 3 , a packaging box edge rolling device comprises: a machine body; a sealing assembly arranged on the machine body to roll the cover of the packaging box; a power source for driving the sealing assembly to operate; a tray 21 arranged on the machine body to support the bottom of the packaging box; a jack 12 rotatably connected to the machine body, one end of the jack 12 abutting the bottom of the tray 21; a protrusion 10 in transmission connection with the output end of the power source, the protrusion 10 abutting the other end of the jack 12, the protrusion 10 having at least one protrusion and at least one recess, in use, the power source drives the sealing assembly to operate while driving the protrusion 10 to rotate, so that the protrusion and the recess of the protrusion 10 alternately contact one end of the jack 12, so that the other end of the jack 12 drives the tray 21 to rise or fall;

[0050] The power source can drive the sealing assembly to rotate and drive the protruding block 10 to rotate at the same time. Since the transmission ratio of the protruding block 10 and the sealing assembly is different, when the sealing assembly rotates for several rounds, the protruding block 10 rotates for one round. When the protruding block 10 rotates, the convex part and the concave part on the surface of the protruding block 10 alternately contact one end of the rocker 12, so that the other end of the rocker 12 drives the tray 21 to rise or fall. Specifically, when the convex part contacts the rocker 12, the rocker 12 is pressed at the end close to the convex part, so that the end of the rocker 12 away from the protruding block 10, that is, the end of the rocker 12 abutting against the tray 21, is lifted, thereby driving the tray 21 on which the packaging box is placed to contact the sealing assembly, so that the cover on the packaging box is crimped, and the sealing of the packaging box is realized. Conversely, when the concave part contacts the rocker 12, the rocker 12 is not pressed at the end close to the concave part, so that the end of the rocker 12 away from the protruding block 10, that is, the end of the rocker 12 abutting against the tray 21, is pressed down by the weight of the tray 21, thereby driving the tray 21 on which the packaging box is placed to be separated from the sealing assembly, and one round of crimping is completed.

[0051] As shown in the figure, in the embodiment, the machine body comprises a machine body 1 and a bracket 2 arranged inside the machine body 1. Figure 1

[0052] The above technical solution can facilitate the installation of the power source, the tray 21 and the rocker 12.

[0053] As shown in the figure, in the embodiment, the packaging box crimping device further comprises a movable rod 19 arranged at the bottom of the tray 21; a linear sliding bearing 17 matched with the movable rod 19, the linear sliding bearing 17 has a plurality of balls 18 in point contact with the outer side surface of the movable rod 19, and the linear sliding bearing 17 is arranged on the machine body 1. Figure 3

[0054] The above technical solution can ensure that the tray 21 can be lifted. When the movable rod 19 rises along the linear sliding bearing 17, the tray 21 is lifted synchronously, and vice versa. When the movable rod 19 falls along the linear sliding bearing 17, the tray 21 falls synchronously, thereby driving the packaging box to contact or separate from the sealing assembly.

[0055] As shown in the figure, in the embodiment, the machine body further comprises a power source arranged in the bracket 2, and the power source is connected with the sealing assembly and the protruding block 10. Figure 2 Figure 3 ​​​As shown, in this embodiment, the packaging box edge-rolling device further includes: a fixed base 13 disposed inside the body 1, the surface of the fixed base 13 having a first pin hole 15, the middle part of the rocker arm 12 having a second pin hole matching the first pin hole 15; a first positioning pin 14 passing through the first pin hole 15 and the second pin hole; a positioning nut 16 cooperating with the first positioning pin 14; the bottom of the movable rod 19 having a through groove for the rocker arm 12 to extend into, the surface of the movable rod 19 having a third pin hole 23, the surface of the rocker arm 12 having a fourth pin hole matching the third pin hole 23, and a second positioning pin 22 passing through the third pin hole 23 and the fourth pin hole;

[0056] like Figure 2 As shown, in this embodiment, the packaging box edge-rolling device further includes: a motor 3 as a power source; a drive pulley 4 connected to the output shaft of the motor 3; multiple sets of bearing seats on the bracket 2; a rotating shaft 7 rotatably connected to one set of bearing seats, one end of the rotating shaft 7 being provided with a driven pulley 5, and a belt 6 being provided between the driven pulley 5 and the drive pulley 4; a worm gear 8 provided at the other end of the rotating shaft 7; a connecting shaft 11 rotatably engaged with one set of bearing seats, the connecting shaft 11 being connected to the rotation center of the protrusion 10; and a worm wheel 9 connected to the connecting shaft 11 and engaged with the worm gear 8.

[0057] The above technical solution enables the sealing assembly to rotate while simultaneously lifting and lowering the tray 21. In use, the motor 3 is started, which drives the drive pulley 4 to rotate. The drive pulley 4 drives the driven pulley 5 to rotate via the belt 6. The driven pulley 5 differentially drives the sealing assembly to rotate. The driven pulley 5 drives the worm gear 8 to rotate. The worm gear 8 drives the connecting shaft 11 to rotate via the worm wheel 9. The connecting shaft 11 drives the protrusion 10 to rotate. The protrusion and recess of the protrusion 10 intermittently and alternately abut against the rocker arm 12, thereby causing the rocker arm 12 to drive the movable rod 19 to rise and fall along the linear sliding bearing 17, which in turn drives the tray 21 connected to the movable rod 19 to rise and fall.

[0058] like Figure 4 As shown, in this embodiment, the packaging box rolling device further includes: a support plate 20 fixedly connected to the upper end of the movable rod 19, the upper end surface of the support plate 20 is provided with a recessed groove 25, and the bottom of the tray 21 is provided with a boss 24 that cooperates with the recessed groove 25.

[0059] The above technical solution allows for easy replacement of different pallets 21 to meet the processing needs of packaging boxes of different specifications. By setting the boss 24 and the recessed groove 25, during the edge rolling process, the sealing component presses down on the packaging box, so that the pallet 21 also exerts pressure on the support plate 20, ensuring the connection stability between the pallet 21 and the support plate 20, and ensuring that the pallet 21 will not fly off the support plate 20.

[0060] like Figure 4As shown, in this embodiment, the boss 24 is provided with a plurality of locking blocks 26 along its outer circumferential surface. Each locking block 26 cooperates with a locking groove 27 formed in the inner wall of the recessed groove 25. The cooperation between the locking block 26 and the locking groove 27 restricts the rotation of the tray 21 relative to the support plate 20.

[0061] The above technical solution can prevent the sealing component from causing the tray 21 to rotate relative to the support plate 20. Relying solely on the pressure of the sealing component is insufficient to ensure that the tray 21 will not rotate relative to the support plate 20 during processing. Therefore, by setting the locking block 26 and the locking groove 27, the rotational freedom between the tray 21 and the support plate 20 can be completely restricted.

[0062] like Figure 5 and Figure 6 As shown, in this embodiment, the packaging box edge-rolling device further includes: a push plate 28 disposed in the slot 27, with the front of the push plate 28 facing the block 26; a spring 31 connected at one end to the back of the push plate 28, so as to drive the push plate 28 to clamp the block 26 through the spring 31; a fixing plate 32 disposed at the other end of the spring 31; a positioning block 33 disposed on the inner wall of the slot 27 for fixing the fixing plate 32; and a guide rod 29 disposed on the back of the push plate 28, which cooperates with the guide groove 30 opened inside the support plate 20.

[0063] The above technical solution can prevent the pallet 21 from falling off the support plate 20 due to external force. By setting the push plate 28, the spring 31 can drive the push plate 28 to fit with the locking block 26, thereby generating a clamping force between the push plate 28 and the locking block 26, which can effectively prevent the pallet 21 from falling off the support plate 20. When it is necessary to disassemble or replace the push plate 28, pull the push plate 28 outward so that the guide rod 29 at one end is pulled out of the guide groove 30 in the support plate 20. Then, pull the fixing plate 32 outward from the groove of the positioning block 33, so that the fixing plate 32, together with the spring 31 and the push plate 28, can be disassembled from the locking groove 27.

[0064] Furthermore, in this embodiment, a magnet is provided at the bottom of the recessed groove 25, and the magnet is used to generate a magnetic attraction force on the metal sheet provided at the bottom of the boss 24.

[0065] The above technical solution can further improve the connection stability between the tray 21 and the support tray 20.

[0066] like Figure 1 As shown, in this embodiment, a trigger rod 34 is provided at one end of the connecting shaft 11, and a switch 35 is provided in the bracket 2;

[0067] The above technical scheme can make the device stop automatically after one round of edge rolling, the switch 35 is connected in series in the relay self-locking structure, when the switch 35 is disconnected, the relay self-locking is released, when the sealing assembly rotates N rounds, the connecting shaft 11 rotates one round, when the connecting shaft 11 rotates one round, the trigger lever 34 drives the switch 35 to trigger, so that the equipment stops, and the next round of sealing is prepared.

[0068] Working principle: when in use, the cover to be rolled is placed at the opening of the packaging box, and the packaging box is placed on the tray 21 together with the cover, the starting button on the surface of the equipment is pressed, the motor 3 is started, the motor 3 drives the driving pulley 4 to rotate, the driving pulley 4 drives the driven pulley 5 to rotate through the belt 6, the driven pulley 5 drives the sealing assembly to rotate at different speeds, the driven pulley 5 drives the worm 8 to rotate, the worm 8 drives the connecting shaft 11 to rotate through the worm wheel 9, the connecting shaft 11 drives the protrusion 10 to rotate, because the transmission ratio of the protrusion 10 and the sealing assembly is not the same, when the sealing assembly rotates multiple rounds, the protrusion 10 rotates one round, when the protrusion 10 rotates, the convex part and the concave part on the surface of the protrusion 10 alternately contact one end of the lever 12, so that the other end of the lever 12 drives the tray 21 to rise or fall, specifically, when the convex part contacts the lever 12, the lever 12 is pressed on the side close to the convex part, so that the other end of the lever 12, that is, the end of the lever 12 abutting against the tray 21, is lifted, thereby driving the packaging box on the tray 21 to contact the sealing assembly, so that the cover on the packaging box is rolled, and the sealing of the packaging box is realized; on the contrary, when the concave part contacts the lever 12, the lever 12 is not pressed on the side close to the concave part, so that the other end of the lever 12, that is, the end of the lever 12 abutting against the tray 21, is pressed down by the weight of the tray 21, thereby driving the packaging box on the tray 21 to be separated from the sealing assembly, and one round of edge rolling is completed.
