In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] Please refer to the following: Figure 1 and Figure 2 The following describes a cardboard padding machine 32 for packaging cartons provided in this application. The cardboard padding machine includes a paper feeding mechanism and a padding mechanism. The padding mechanism includes a work frame 1, with baffles 2 at both ends. The baffles 2 have a first semi-circular receiving groove 3 and a second U-shaped receiving groove 4. The first receiving groove 3 is located below the second receiving groove 4 and communicates with it. A paper feed groove 5 connects the first receiving groove 3 and the second receiving groove 4. A lifting transmission assembly is provided at the front end of the baffle 2. The lifting transmission assembly includes a telescopic cylinder 6, which is fixed to the baffle 2. The driving end of the telescopic cylinder 6 is connected to a lifting transmission roller 7. The lifting transmission roller 7 cooperates with the first receiving groove 3 and the second receiving groove 4. The lifting transmission roller 7 is connected to a driven transmission roller 9 via a crank arm gear seat 8 and a gear assembly. The gear assembly is fixed to the inner end of the crank arm gear seat 8. The inner side of the work frame 1 is provided with a transport drive assembly, and below the transport drive assembly is a cardboard gripping assembly. The cardboard gripping assembly includes a finger cylinder 11 and a figure-eight gripper 12 installed at the front end of the finger cylinder 11.

[0023] Through the coordinated operation of the lifting transmission component, the transport drive component, and the cardboard clamping component, while the carton is being transported on the work frame 1 by the transport drive component, the cardboard clamping component clamps the cardboard 32. With the cooperation of the lifting transmission component and the first receiving groove 3 and the second receiving groove 4, the cardboard 32 is placed on the bottom of the moving carton. As the carton is transported synchronously, the effect of lining the carton with cardboard is achieved, which greatly improves the efficiency of lining the carton during packaging, shortens the overall packaging time of the carton, and reduces production costs.

[0024] Among them, such as Figure 5As shown, the gear assembly includes a first gear 13, a second gear 14, a third gear 15, a fourth gear 16, and a fifth gear 17. The first gear 13 is fixed to the lifting transmission roller 7. The first gear 13 meshes with the second gear 14, the second gear 14 meshes with the third gear 15, the third gear 15 meshes with the fourth gear 16, and the fourth gear 16 meshes with the fifth gear 17. The fifth gear 17 is fixed to the driven transmission roller 9. All gears, including the first gear, second gear 14, third gear 15, fourth gear 16, and fifth gear 17, are fixed. On the crank arm gear seat 8, and distributed according to the outer curve of the crank arm gear seat 8, the telescopic cylinder 6 is activated, driving the lifting transmission roller 7 to move from the first receiving groove 3 to the second receiving groove 4, realizing the lifting of the lifting transmission roller 7. At the same time, due to the curved lifting movement of the lifting transmission roller 7, the first gear 13 meshes with the second gear 14, the third gear 15, the fourth gear 16 and the fifth gear 17, so that while the lifting transmission roller 7 is lifting, it itself and the driven transmission roller 9 also rotate, which makes it easier to place the cardboard 32 at the bottom of the carton.

[0025] Among them, such as Figure 4 As shown, the transport drive assembly includes a first motor 18, which is fixed to the baffle 2. The output end of the first motor 18 is fixed with a drive wheel. Multiple auxiliary drive rollers 20 are provided on both sides of the lifting drive roller 7 and the driven drive roller 9. Each auxiliary drive roller 20 has two driven wheels at both ends. The driven wheels between adjacent auxiliary drive rollers 20 are connected by a synchronous belt 21. The drive wheel is connected to the two driven wheels above it by the synchronous belt 21. The driven drive roller 9 also has driven wheels at both ends. The driven wheels of the driven drive roller 9 are connected to the driven wheels of the auxiliary drive roller 20 located on one side of the lifting drive roller 7 by the synchronous belt 21. The driven wheels of the auxiliary drive roller 20 on one side of the driven drive roller 9 are connected to the driven wheels of the auxiliary drive roller 20 adjacent to the driven drive roller 20 connected to the driven drive roller 9 by the synchronous belt 21.

[0026] Furthermore, a first tensioning support wheel 22 is provided between the driven drive roller 9 and the auxiliary drive roller 20, and a second tensioning support wheel 23 is provided between the auxiliary drive rollers 20 on both sides of the driven drive roller 9. Both are used to maintain the predetermined track of the synchronous belt 21, prevent sagging or deviation, and play the role of tensioning support.

[0027] Furthermore, such as Figure 3 As shown, the cardboard gripping assembly is provided with a linear motion module 10, which is located at the lower end of the auxiliary transmission roller 20. The upper end of the linear motion module 10 is fixed with a first connecting seat 31. The two ends of the first connecting seat 31 are provided with finger cylinders 11, and the front end of the finger cylinders 11 is provided with a figure-eight gripper 12. The linear motion module 10 drives the finger cylinders 11 to reciprocate, and uses the figure-eight gripper 12 to grip the cardboard 32.

[0028] In actual production, the first motor 18 drives the drive wheel to rotate, which in turn drives the two driven wheels connected to it to rotate, thereby driving the two auxiliary drive rollers 20 to rotate. This, in turn, drives the auxiliary drive rollers 20 on one side of the driven drive rollers 9 to rotate synchronously. Furthermore, as the lifting drive roller 7 rises and falls, it drives the driven drive roller 9 to rotate, which in turn drives the auxiliary drive rollers 20 connected to it to rotate. Since adjacent auxiliary drive rollers 20 are connected by a synchronous belt 21, they also drive the auxiliary drive rollers 20 on one side of the lifting drive roller 7 to rotate. Through this structural design, the start of the first motor 18 can drive multiple auxiliary drive rollers 20 to rotate synchronously, thus achieving the purpose of carton transportation. During carton transportation, as the lifting drive roller 7 rises and falls, the cardboard 32 is fed into the bottom of the carton and transported along with the carton to the next workstation.

[0029] In one embodiment, such as Figure 6-7 As shown, the paper feeding mechanism includes a material box 24, which holds multiple layers of cardboard 32. A first pusher plate 25 is located below the material box 24, and a second pusher plate 26 is located above the first pusher plate 25. Openings are located on the lower front and rear sides of the material box 24. The second pusher plate 26 is located at the rear opening of the material box 24. The thickness of the opening is greater than the thickness of the cardboard 32 and the second pusher plate 26, and the length of the first pusher plate 25 is not less than the sum of the width of the material box 24 and the width of the second pusher plate 26. An adjusting plate 27 is located on the rear side of the material box 24. The adjusting plate 27 can appropriately adjust the size of the opening to accommodate cardboard 32 of different thicknesses, ensuring that the second pusher plate 26 can push out only the bottom layer of cardboard 32 while passing through the opening.

[0030] Furthermore, such as Figure 8 As shown, a second motor 19 is provided below the first pusher plate 25. The output end of the second motor 19 is connected to a second connecting seat 33, which is fixed below the first pusher plate 25.

[0031] In actual production, the second motor 19 operates, driving the first pusher plate 25 to move. The first pusher plate 25 drives the second pusher plate 26 to move towards the opening of the material box 24. After the second pusher plate 26 enters the material box 24, it pushes out the bottom layer of paper 32 from the opening on the front side of the material box 24. The bottom layer of paper 32 moves towards the paper feed slot 5 along with the first pusher plate 25. The original position of the bottom layer of paper 32 is occupied by the second pusher plate 26. After the bottom layer of paper 32 enters the paper feed slot 5 and is picked up by the paper clamping component, the second motor 19 drives the first pusher plate 25 to retract. At the same time, the second pusher plate 26 exits from the rear opening. The original second-to-last layer of paper 32 moves downward to become the bottom layer of paper 32. With the cooperation of the adjusting plate 27 and the second pusher plate 26, it is ensured that only the bottom layer of paper 32 is fed each time. This structural design not only improves the paper feeding efficiency but also ensures the accuracy of paper feeding, further improving the efficiency of carton packing and padding paper, and is widely applicable to industrial production.

[0032] Furthermore, guide rails 28 are provided on both sides of the second motor 19, and sliders 29 are fixed on the guide rails 28. The sliders 29 are fixed on the rectangular hollow steel, and the rectangular hollow steel is fixed on the frame 30, thereby ensuring the stability of the running trajectory of the first pusher plate 25 and the second pusher plate 26.

[0033] Furthermore, the feed chute of the baffle 2 is provided with a notch for the guide rail 28 to compensate for the passage.

[0034] The specific working principle of this utility model is as follows: (1) After the multi-layer cardboard 32 is placed into the material box 24, the second motor 19 runs and drives the first pusher plate 25 to move. The first pusher plate 25 drives the second pusher plate 26 to move towards the opening of the material box 24. After the second pusher plate 26 enters the material box 24, it pushes the bottom layer of cardboard 32 out of the opening on the front side of the carton. The bottom layer of cardboard 32 moves towards the paper feed groove 5 with the first pusher plate 25. The original position of the bottom layer of cardboard 32 is occupied by the second pusher plate 26.

[0035] (2) When the bottom layer of paperboard 32 enters the paper feed slot 5, the linear motion module 10 drives the finger cylinder 11 to move towards the first push plate 25, the figure-eight gripper 12 picks up the paperboard 32 and retracts, and at this time one end of the paperboard 32 is above the lifting transmission roller 7. At the same time, the second motor 19 drives the first push plate 25 to retract, and the second push plate 26 exits from the rear opening. The original second-to-last layer of paperboard 32 moves downward to become the bottom layer of paperboard 32.

[0036] (3) At the same time, the telescopic cylinder 6 drives the lifting transmission roller 7 to rise and rotate, and drives the driven transmission roller 9 to rotate through the gear assembly. The first motor 17 drives multiple auxiliary transmission rollers 20 to rotate using the synchronous belt 21. When the carton is transported and moved on the multiple auxiliary transmission rollers 20, the lifting transmission roller 7 drives the cardboard 32 to move to the upper end of the auxiliary transmission roller 20. As the carton moves, it is placed under the carton, completing the operation of placing the cardboard 32.

[0037] It is worth noting that the telescopic cylinder 6, the first motor 17, the second motor 19, and the linear motion module 10 mentioned in this utility model are all controlled by an external PCT control system.
