At the same time, the cross-section of the fixed shaft 73 is a regular polygon, which can guide the movement of the bearing 74 on the fixed shaft 73, ensuring the accuracy of the movement and avoiding subsequent synchronous rotation with the pressing roller 72.

[0050] In one embodiment of the present utility model, the pressing assembly 7 also includes a guide plate 3, which is arranged on the base 1, and a guide block 31 is provided on the guide plate 3, and the guide block 31 is arranged opposite to the pressing roller 72. An ascending inclined surface 32 is provided on the guide block 31, and the ascending inclined surface 32 is connected to the guide surface 33, and the guide surface 33 is connected to the descending inclined surface 34, and the free end of the descending inclined surface 34 is arranged opposite to the top of the box body.

[0051] Specifically, in the initial position, the pressing roller 72 is in contact with the rising inclined surface 32, that is, the pressing frame 6 is placed on one side of the guide block 31, and the handle on the pressing frame 6 is pulled to make the pressing roller 72 move along the rising inclined surface 32 through the guide surface 33, and then move to the top of the box body through the descending inclined surface 34 under the action of the gravity of the counterweight block 65, so that the pressing roller 72 can fall more smoothly on the top of the box body, avoiding the sudden drop of the pressing roller 72 to cause damage to the surface of the box body, thereby ensuring the stability of the pressing and mounting.

[0052] In one embodiment of the present utility model, the clamping assembly 5 includes a clamping frame 51, a plurality of guide sleeves are provided on the clamping frame 51, a guide rod 52 is passed through the guide sleeve, one end of the guide rod 52 is connected to the fixed block, and the other end is connected to the clamping plate 53, a clamping spring 54 is sleeved on the guide rod 52, one end of the clamping spring 54 abuts against the clamping plate 53, and the other end abuts against the clamping frame 51, a support plate 55 is provided on the clamping plate 53, a guide cone plate is provided at the bottom of the support plate 55, and a guide cone surface 56 is provided on the guide cone plate.

[0053] Specifically, the two sides of the box body move along the guide slope on the guide cone plate, so that the box body moves the support plate 55 toward the clamping frame 51 and compresses the clamping spring 54 until the bottom of the box body is positioned through the positioning area 23. The support plates 55 on both sides clamp and position the two sides of the box body under the reaction force of the clamping spring 54. The positioning accuracy is good, which reduces the defective rate of product attachment, improves product quality, saves time, and improves work efficiency.

[0054] In one embodiment of the present utility model, the attachment component 4 includes a mounting plate 41, a movable plate 42 is slidably provided on the mounting plate 41, a handle 43 is provided on the movable plate 42, bearings 74 seats 44 are provided on both sides of the movable plate 42, a rotating shaft 45 is provided between the two bearings 74 seats 44, a guide groove 47 is provided on the bearing 74 seat 44, a clamping spring 48 is provided on the guide groove 47, and an attachment roller 46 is provided on the rotating shaft 45.

[0055] Specifically, pushing the handle 43 drives the attachment roller 46 on the movable plate 42 to move toward the top of the box body. The lowest point of the attachment roller 46 is slightly lower than the height of the box body, so that when the attachment roller 46 is pressed against the top of the step, the upward movement of the rotating shaft 45 will compress the clamping spring 48 on the guide groove 47. Under the reaction force of the clamping spring 48, the attachment roller 46 is always pressed against the attachment position of the box body, effectively improving the portability of the production action and effectively improving the production efficiency, with good practicality and ensuring the pressing and attaching effect.

[0056] In one embodiment of the present utility model, a limit baffle 49 is provided on the mounting plate 41, and the limit baffle 49 is arranged opposite to the movable plate 42. A first magnet 491 is provided on the limit baffle 49, and a second magnet is provided on the movable plate 42. The first magnet 491 is magnetically connected to the second magnet.

[0057] Specifically, after the pressing and attaching is completed, the limiting baffle 49 abuts against the movable plate 42 so that the first magnet 491 is magnetically connected to the second magnet, thereby preventing the movable plate 42 from shaking. At the same time, it also serves to improve the cleanliness of the front of the attachment component 4, thereby avoiding the accumulation of excess parts that block the operation of technicians.

[0058] Usage process

[0059] The box body is placed in the positioning area 23 formed by the multiple positioning blocks 21. The four corners of the box body are positioned by the positioning grooves 22 on the positioning blocks 21. At the same time, the two sides of the box body move along the guide slopes on the guide cone plate, so that the box body moves the support plate 55 toward the clamping frame 51 and compresses the clamping spring 54 until the bottom of the box body passes through the positioning area 23 and is positioned. The support plates 55 on both sides clamp the two sides of the box body in position under the reaction force of the clamping spring 54.

[0060] In the initial position, the pressing roller 72 abuts against the ascending inclined surface 32, that is, the pressing frame 6 is placed on one side of the guide block 31. The handle on the pressing frame 6 is pulled, so that the pressing roller 72 moves along the ascending inclined surface 32 and passes through the guide surface 33. Then, under the action of the gravity of the counterweight 65, it moves to the top of the box body through the descending inclined surface 34. The handle on the pressing frame 6 is pulled to drive the pressing roller 72 to repeatedly press the box body until the lamination is completed, and the pressing frame 6 returns to the initial position.

[0061] The pushing handle 43 drives the attaching roller 46 on the movable plate 42 to move toward the top of the box body. The lowest point of the attaching roller 46 is slightly lower than the height of the box body, so that when the attaching roller 46 is pressed against the top of the step, the upward movement of the rotating shaft 45 will compress the clamping spring 48 on the guide groove 47. Under the reaction force of the clamping spring 48, the attaching roller 46 is always pressed against the attaching position of the box body to ensure the pressing and attaching effect. After the pressing and attaching is completed, the limit baffle 49 abuts against the movable plate 42 so that the first magnet 491 is magnetically connected to the second magnet to avoid shaking of the movable plate 42 and affecting normal processing. After the semi-automatic jig is used to assemble the packaging box, it replaces the manual jig to assist in attachment and rolling. No manual attachment is required, so that the product is attached smoothly.

[0062] The above-described embodiments are merely preferred embodiments for the purpose of fully illustrating the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are within the scope of protection of the present invention.
