[0015] 1. In this utility model, through the cooperation of components such as the motor, rotating rod, conveyor belt, and protective plate inside the feeding and protection assembly, automatic feeding via the conveyor belt is achieved. The extension and retraction mechanism of the electric cylinder can control the movement of the rack, gear, and rotating rod to drive the protective plate to one side of the conveyor belt, preventing materials from accidentally falling during transportation. This protective plate can completely cover both sides of the conveyor belt, thereby effectively preventing materials from falling from the side and improving the safety of material transportation.

[0016] 2. In this utility model, through the cooperation between the rectangular box, oil outlet pipe, extrusion rod, and other components inside the smooth-running assembly, the extrusion rod is driven by the telescopic movement of the electric cylinder, which in turn pushes the push rod to move and pushes the slider to open the notch. This allows lubricating oil to be smoothly replenished to the top of the rectangular box and then flow out through the oil outlet pipe. The replenishment and flow of lubricating oil, especially for the lubrication of the rotating rod and conveyor belt, can effectively reduce the friction between them. The reduction of friction not only improves the flexibility of mechanical parts but also prevents jamming caused by excessive friction, ensuring the smooth operation of the automatic box packing machine and avoiding downtime or production interruption.

[0028] Example 1

[0029] Referring to Figures 1-5, the first embodiment of this utility model proposes a feeding structure for an automatic box packing machine, including a support leg 1. A base plate 2 is fixedly connected to the top of the support leg 1. A feeding protection component 3 is provided on the top of the base plate 2. The feeding protection component 3 includes a housing 31, which is disposed on the side of the base plate 2. A box packing 32 is provided on the top of the base plate 2. A support rod 35 is fixedly connected to the side of the base plate 2. A motor 36 is fixedly connected to one end of the support rod 35. A rotating rod 33 is fixedly connected to the output shaft of the motor 36. A conveyor belt 34 is provided on the circumferential surface of the support leg 1. A support plate 318 is fixedly connected to the outer wall of the support leg 1. An electric cylinder 319 is fixedly connected to the top of the support plate 318. A rotating rod 38 is rotatably connected to the side of the base plate 2. A protective plate 310 is fixedly connected to the circumferential surface of the rotating rod 38. A gear 39 is fixedly connected to one end of the rotating rod 38. An L-shaped plate 311 is fixedly connected to the side of the base plate 2. A rack 312 is slidably connected to the side of the L-shaped plate 311. One end of the electric cylinder 319 is fixedly connected to the bottom of the rack 312.

[0030] The rack 312 and gear 39 mesh with each other. The protective plate 310 is located on the side of the conveyor belt 34. One end of the rotating rod 38 is rotatably connected to the moving rod 314. The top of the moving rod 314 is fixedly connected to the thin rod 315. The design of the thin rod 315 and the moving rod 314 helps to temporarily restrict the position of the rotating rod 38 and prevent the rotating rod 38 from rotating arbitrarily.

[0031] The conveyor belt 34 is located on the displacement trajectory of the protective plate 310. The side of the L-shaped plate 311 is slidably connected to the limiting rod 313. The end of the limiting rod 313 away from the L-shaped plate 311 is fixedly connected to the side of the rack 312. The design of the limiting rod 313 helps to limit the movement trajectory of the rack 312 and prevent the movement trajectory of the rack 312 from deviating.

[0032] Two protective plates 310 are provided and are symmetrical to each other along the vertical central axis of the conveyor belt 34. A shaped plate 316 is fixedly connected to the side of the base plate 2. A switch 37 is provided on the side of the motor 36. The design of the switch 37 is conducive to direct control of the motor 36.

[0033] The irregular plate 316 has a slot 317 on its side. The slot 317 is located on the displacement trajectory of the thin rod 315. Several slots 317 are provided and are arranged linearly on the side of the irregular plate 316. The design of the slot 317 is conducive to inserting the thin rod 315 into the slot 317, thereby temporarily restricting the moving rod 314 and the thin rod 315.

[0034] In this embodiment, pressing switch 37 starts motor 36. Motor 36 rotates, causing rotating rod 33 to rotate, which in turn rotates conveyor belt 34. There are two rotating rods 33, symmetrically positioned along the vertical central axis of conveyor belt 34. Rotating one rotating rod 33 drives the conveyor belt 34, and vice versa, ensuring stable rotation of the conveyor belt 34. Materials to be transported are placed on the conveyor belt 34 for automatic loading. To prevent materials from accidentally falling off the conveyor belt during loading... If the conveyor belt 34 falls, the electric cylinder 319 will be activated, extending its telescopic end upwards. This extension will cause the rack 312 to move upwards. The rack 312 and gear 39 will mesh together. When the rack 312 moves upwards, it will cause the gear 39 to rotate clockwise. The clockwise rotation of the gear 39 will then cause the rotating rod 38 to rotate clockwise. The clockwise rotation of the rotating rod 38 will cause the protective plate 310 to rotate clockwise, moving it closer to the side of the conveyor belt 34. This will cause the protective plate 310 to stand upright on the side of the conveyor belt 34, blocking its side. Two protective plates 310 are provided. When operated from both sides simultaneously, they will block both sides of the conveyor belt 34, protecting both sides of the conveyor belt 34. Then, rotating the moving rod 314 and the thin rod 315 towards the side closer to the irregular plate 316 will engage the thin rod 315 into the slot 317, temporarily fixing the position of the rotating rod 38 and the protective plate 310 to prevent slippage. Due to the symmetrical design between the rotating rod 33 and the conveyor belt 34, the stable rotation of the conveyor belt 34 can be ensured. Even if one rotating rod 33 drives the rotation of the conveyor belt 34, the other rotating rod 310 will not be affected. 3 can also be further rotated by the drive of the conveyor belt 34, avoiding instability caused by uneven transmission of power in the conveyor belt 34. This design can reduce failures and extend the service life of the equipment. The extension and retraction mechanism of the electric cylinder 319 can drive the protective plate 310 to move to one side of the conveyor belt 34 by controlling the movement of the rack 312, gear 39 and rotating rod 38, to prevent materials from falling accidentally during transportation. This protective plate 310 can completely cover both sides of the conveyor belt 34, thereby effectively preventing materials from falling from the side and improving the safety of material transportation.

[0035] Example 2

[0036] Referring to Figures 1 to 5, this is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: a smooth running component 4 is provided on the side of the base plate 2. The smooth running component 4 includes a crossbar 41, one end of which is fixedly connected to the side of the base plate 2. A rectangular box 42 is fixedly connected to the side of the crossbar 41. A slider 43 is slidably connected to the inner wall of the rectangular box 42. A square plate 44 is fixedly connected to the inner wall of the rectangular box 42. A push rod 48 is fixedly connected to the bottom of the slider 43. The end of the push rod 48 away from the slider 43 passes through the bottom of the rectangular box 42. An oil outlet pipe 47 passes through the side of the rectangular box 42. A pressing rod 411 is fixedly connected to the telescopic end of the electric cylinder 319. Lubricating oil flows out through the oil outlet pipe 47 to lubricate the rotating rod 33, thereby reducing the friction between the rotating rod 33 and the conveyor belt 34 during operation.

[0037] The push rod 48 is located on the displacement trajectory of the extrusion rod 411. The end of the oil outlet pipe 47 away from the rectangular box 42 is located on the side of the rotating rod 33. A round rod 46 is fixedly connected to the inner wall of the rectangular box 42. The end of the round rod 46 away from the rectangular box 42 passes through the bottom of the slider 43. The design of the round rod 46 is beneficial to restrict the slider 43 and prevent the movement trajectory of the slider 43 from deviating.

[0038] A spring 45 is fixedly connected to the inner wall of the rectangular box 42. The end of the spring 45 away from the rectangular box 42 is fixedly connected to the top of the slider 43. An adding tube 49 passes through the top of the rectangular box 42. A plug 410 is provided on the side of the adding tube 49. The design of the adding tube 49 is conducive to replenishing the rectangular box 42 with lubricating oil. The design of the plug 410 is conducive to blocking the adding tube 49 and preventing the lubricating oil from leaking out.

[0039] Compared to Embodiment 1, further, the electric cylinder 319 extends upwards, which drives the extrusion rod 411 to move upwards. The push rod 48 is located on the movement trajectory of the extrusion rod 411. When the extrusion rod 411 moves upwards, it extrudes the push rod 48, pushing the push rod 48 into the rectangular box 42. The push rod 48 into the rectangular box 42 drives the slider 43 to move. The slider 43 is located between the two square plates 44. When the slider 43 moves, a gap is opened between the two square plates 44. The adding pipe 49 is located on the side of the rectangular box 42. Lubricating oil is added to the inside of the rectangular box 42 through the adding pipe 49. The added lubricating oil is located at the bottom of the two square plates 44 and the slider 43, while the oil outlet pipe 47 is located at the top of the two square plates 44 and the slider 43. Therefore, the lubricating oil cannot flow out. When the gap is opened, it can spread upwards through the gap, allowing the lubricating oil to pass through the gap. The lubricating oil flows over the two square plates 44 and the slider 43, and then flows out through the oil outlet pipe 47. The end of the oil outlet pipe 47 away from the rectangular box 42 is located on the side of the rotating rod 33. The flowing lubricating oil will flow to the side of the rotating rod 33 to lubricate the rotating rod 33 and the conveyor belt 34, reducing the friction between the rotating rod 33 and the conveyor belt 34 and reducing the possibility of jamming during feeding. The extension and retraction of the electric cylinder 319 drives the extrusion rod 411, which in turn pushes the push rod 48 to move, pushing the slider 43 to open the notch, so that the lubricating oil can be smoothly replenished to the top of the rectangular box 42 and then flow out through the oil outlet pipe 47. Through the replenishment and flow of lubricating oil, especially the lubrication of the rotating rod 33 and the conveyor belt 34, the friction between them can be effectively reduced. The reduction of friction not only improves the flexibility of mechanical parts, but also prevents jamming caused by excessive friction, ensuring the stable operation of the equipment and avoiding downtime or production interruption.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
