Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard box manufacturing technology, and in particular to a cardboard box discharge device. Background Technology
[0002] A typical carton printing production line includes processes such as paper feeding, printing, slotting, die-cutting, folding, and gluing. After gluing, the cartons are stacked and counted by a counting and discharge device before being transported to an automatic bundling machine for packaging into bundles for easy transport and sale.
[0003] Existing discharge devices typically have a baffle between the stacking mechanism and the discharge mechanism to prevent stacked cartons from tipping over, creating a height difference between the two. After each order is completed, this height difference results in some cardboard remaining in the stacking section of the stacking mechanism, which cannot be discharged. This requires manual removal of the remaining cardboard to discharge all the cardboard, increasing downtime, affecting production continuity, reducing production efficiency, and increasing additional labor costs, thus hindering the fully automated production of the entire machine.

[0025] Example
[0026] like Figure 1-4As shown, a carton discharge device includes a pushing mechanism 1, a stacking mechanism 2, and a lifting mechanism 3. The stacking mechanism 2 includes multiple stacking conveyor belts arranged at intervals, with the front ends of the multiple stacking conveyor belts forming stacking sections 21. The stacking sections 21 are located between the feeding conveyor belt (not shown in the figure) and the discharging conveyor belt 4. The pushing mechanism 1 is located near the feeding end of the stacking section 21 and is used to push the stacked cartons in the stacking section 21 to the discharging conveyor belt 4. It includes a pushing frame 11 and a lifting assembly 12. The pushing frame 11 can move up and down through the lifting assembly 12. The lifting mechanism 3 is located below the stacking section 21 and includes multiple lifting wheels 31 arranged in the intervals of each stacking conveyor belt. The lifting wheels 31 are located near the discharging end of the stacking section 21. The lifting wheel 31 and the pushing frame 11 are located at both ends of the cardboard. The two work together to lift the remaining cardboard in the stacking section 21 to the pushing height (the height of the discharge conveyor belt), making up for the height difference. Then, the cardboard is pushed to the discharge conveyor belt through the pushing mechanism 1 to realize the automatic discharge of the cardboard.
[0027] Among them, such as Figure 1-3 As shown, the lifting mechanism 3 also includes a lifting cylinder 32, a lifting plate 33, an extension rod 34, and a lifting wheel seat 35. The lifting cylinder 32 is mounted on the stacking mechanism 2, and its output end is provided with a lifting plate 33. Multiple lifting wheels 31 are arranged side by side above the lifting plate 33. Each lifting wheel 31 is mounted on a corresponding lifting wheel seat 35 and is rotatably connected to the lifting wheel seat 35. The extension rod 34 is inserted in each stacking conveyor belt interval, with its upper end connected to the lifting wheel seat 35 and its lower end connected to the lifting plate 33.
[0028] In addition, such as Figure 1 , 2As shown in Figure 4, the pushing mechanism 1 further includes a driving assembly 13 for driving the pushing frame 11 to translate. The driving assembly 13 includes a pushing slide rod 131, a sliding plate 132, a main rotating shaft 133, a driven rotating shaft 134, and a servo motor 135. The output end of the servo motor 135 is connected to the main rotating shaft 133 via a coupling. The driven rotating shaft 134 and the main rotating shaft 133 are both fixed on the pushing mounting frame 136 via bearing seats. Synchronous pulleys 137 are provided at corresponding positions on the driven rotating shaft 134 and the main rotating shaft 133. A synchronous belt is wound around the synchronous pulleys 137 at the corresponding positions. There are multiple pushing slide rods 131 arranged along the synchronous belt conveying direction. A corresponding slide rail 138 is provided below the pushing slide rod 131. A slider that cooperates with the slide rail 138 is provided on the pushing mounting frame 136. The ends of the multiple pushing slide rods 131 are connected to the sliding plate 132. The pushing frame 11 and the lifting assembly 12 are both connected to the sliding plate 132. This utility model uses a servo motor driven synchronous belt transmission structure to drive the pusher 11 to move horizontally. Its push speed is controllable and adjustable, and the push stroke is also adjustable. It is easy to adjust. According to the size of the cardboard, the servo drive component automatically calculates the push distance, which can adapt to the push of more sizes of carton.
[0029] The pusher frame 11 includes an upper connecting plate 111 and a plurality of push rods 112 disposed below the upper connecting plate 111. The bottom of the push rod 112 is provided with an insert 113 that can be inserted into stacked cartons.
[0030] The lifting assembly 12 includes a lifting cylinder 121 and guide rods 122. The lifting cylinder 121 is fixed on the sliding plate 132, and its telescopic end is connected to the upper end of the pusher frame 11. Multiple guide rods 122 are provided, located on the pusher frame 11, and are slidably connected to linear bearings provided on the sliding plate 132. In this embodiment, there are two guide rods 122, located on both sides of the lifting cylinder 121, and corresponding to the push rods 112 one by one.
[0031] In addition, such as Figure 1 , 2 As shown, the aforementioned carton discharge device also includes a paper pressing mechanism 5. The paper pressing mechanism 5 includes at least one paper pressing component. In this embodiment, two paper pressing components are provided, positioned between adjacent cardboard sheets. Each paper pressing component includes a second slide rail 51 and a paper pressing frame 52. The second slide rail 51 is mounted on the push mounting frame 136 of the push mechanism 1. The paper pressing frame 52 is slidably connected to the second slide rail 51 via a slider, and the paper pressing frame 52 is provided with multiple paper pressing wheels 53. These multiple paper pressing wheels 53 are arranged along the carton conveying direction to press against the top of the stacked cartons. The paper pressing frame 52 and the paper pressing wheels 53 are in a floating state, movably connected to the stacked cardboard sheets, and rise and fall with the height of the cardboard stack, ensuring that the cartons are stacked neatly and discharged off-center.
[0032] The working principle of this utility model is as follows: After the current order is completed, the lifting cylinder 32 is started, driving the lifting wheel 31 to rise. The lifting wheel 31 lifts and supports the front end of the remaining cardboard. Then, the insert plate 113 of the pusher hooks the tail end of the cardboard. The lifting cylinder 121 drives the pusher 11 to rise. At this time, the cardboard rises to the height of the discharge conveyor belt 4 through the cooperation of the lifting wheel 31 and the insert plate 113. Then, the drive assembly 13 drives the pusher 11 to move, pushing the cardboard to the discharge conveyor belt 4, and discharging all the remaining cardboard on the stacking part 21.
[0033] This utility model, through technological improvements and upgrades, can discharge any number of remaining cardboard sheets in the stacking section at once, eliminating the need to stop the machine and manually remove the remaining cardboard from the equipment. The equipment can discharge the cardboard automatically, reducing order completion time, improving production efficiency, saving labor costs, and enabling continuous fully automated production.
