Description

Technical Field

[0001] This utility model relates to the field of box gluing and packing, specifically to a feeding mechanism for a box packing machine. Background Technology

[0002] With the increasing demand for automated and efficient production in the packaging industry, integrating carton gluing machines with case packing machines to achieve full-process automation from cardboard folding to finished product packaging has become a technological development trend. Currently, automated case packing solutions mostly employ robotic arms or material handling devices with suction functions. See the invention patent application CN118025578A, entitled "An Integrated Carton Gluing and Case Packing Machine." However, these solutions have limitations: First, whether it's a robotic arm gripper or a vacuum nozzle, it can usually only grasp a single or a limited number of cartons at a time, making it difficult to match the packing rhythm with the output speed of high-speed carton gluing machines, leading to waiting times in subsequent processes or downtime in previous processes. Second, complex robotic arms or suction mechanisms are costly, and when frequently grasping folded cartons with potentially uneven surfaces or soft materials, there is a risk of product damage, insecure grip, or dropping. Therefore, a cleverly designed and stable feeding mechanism is still needed to reliably deliver folded cartons to the case packing stage. Utility Model Content

[0003] In view of the technical problems existing in the background art, the technical problem to be solved by this utility model is to provide a feeding mechanism for a case packing machine that is efficient, stable and compact in structure.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: the feeding mechanism of the box packing machine is characterized in that it includes a feeding conveying device and a distributing conveying device, wherein the distributing conveying device is connected to the end of the feeding conveying device; The feeding and conveying device includes a conveyor belt; The material distribution and conveying device includes an upper conveying component, a lower conveying component, and a material distribution component.

There is a feeding gap between the material distribution baffle and the lower conveyor belt.

[0005] The feeding conveyor transports the material to the sorting conveyor. The sorting component causes the material to be stacked in an orderly manner between the upper and lower conveyor belts, and is then held and conveyed by the upper and lower conveyor belts, so that the material can be stably conveyed into the subsequent loading conveyor to achieve boxing.

[0006] Preferably, the upper conveying component further includes an upper drive wheel and several guide wheels, the upper drive wheel and several guide wheels are rotatably mounted on the frame, and the upper conveyor belt is disposed on the upper drive wheel and several guide wheels; The lower conveying component also includes a lower drive wheel and a roller assembly. The roller assembly includes several rollers. The lower drive wheel and several rollers are rotatably mounted on the frame.

The upper conveyor belt sequentially passes over the starting guide roller, the compensating guide roller, the fixed guide roller, and the ending guide roller. The fixed guide roller and the ending guide roller are mounted on a mounting plate, while the compensating guide roller, the starting guide roller, and the material distribution baffle are mounted on a movable plate. The material leans against the lower conveyor belt and moves upward under its drive, entering the space between the upper and lower conveyor belts. Sufficient space must be provided between the material distribution baffle and the conveyor belts for the material. When the material specifications change, the height of the starting end of the upper conveying component is adjusted accordingly by adjusting the height of the movable plate to meet the material conveying requirements.

[0008] Preferably, the movable plate has teeth, and the mounting plate has a gear, which meshes with the teeth on the movable plate. Rotation of the gear moves the movable plate, facilitating adjustment and improving the accuracy of the adjustment.

[0009] Preferably, the material distribution component further includes a connecting plate and an adjusting assembly for adjusting the size of the feeding gap, wherein the connecting plate is connected to the movable plate; The conveying length of the lower conveyor belt between the material distribution baffle and the feeding conveyor device is matched to the length of the material.

If there is material piled up at the end of the feeding conveying device, the material supports the movable end of the spring, and the sensor collects the spring information. When there is no material at the end of the feeding conveying device, the movable end of the spring droops, the sensor does not collect the spring information, and the material distribution and conveying device stops conveying until material is fed in.

[0020] The following describes the embodiments and related details and working principles of this utility model with reference to the accompanying drawings. In the figures, the X-axis is horizontal and the Y-axis is vertical. The feeding mechanism of this type of box packer includes a feeding conveyor 3 and a distributing conveyor 4, the distributing conveyor being connected to the end of the feeding conveyor. The feeding conveyor includes a conveyor belt 31. The distributing conveyor 4 includes an upper conveying component, a lower conveying component, and a distributing component. The upper conveying component includes an upper conveyor belt 41, and the lower conveying component includes a lower conveyor belt 42. The upper and lower conveyor belts clamp and convey materials from bottom to top. The beginning of the lower conveyor belt 42 is not higher than the end of the conveyor belt 31, and the beginning of the upper conveyor belt 41 is higher than the conveyor belt. The material distribution component includes a material distribution baffle 413, which is positioned above the conveyor belt and adjacent to the beginning of the upper conveyor belt 41. A feeding gap exists between the material distribution baffle 413 and the lower conveyor belt 42, allowing material to enter between the upper and lower conveyor belts 41 and 42. The material 6 on the conveyor belt 31 is stacked, with the next piece overlapping the previous one. The conveyor belt 31 transports the material forward, and the material 6 enters the lower conveyor belt 42, which then transports it upwards. The material 6 rests vertically and obliquely against the lower conveyor belt. (See attached image.) Figure 3 The material following behind is tilted, and the material on the conveyor belt gradually changes from horizontal to tilted. The material enters between the upper conveyor belt 41 and the lower conveyor belt 42 under the conveying of the lower conveyor belt 42. The material distribution baffle 413 blocks the material from above, so that the material in front enters between the upper and lower conveyor belts first, and the material behind enters in sequence. Under the clamping and conveying of the upper conveyor belt 41 and the lower conveyor belt 42, the material is conveyed from bottom to top, preparing for the subsequent top-down boxing.

[0021] The upper conveying component also includes an upper drive wheel and several guide wheels, which are rotatably mounted on the frame 5. The upper conveyor belt 41 is mounted on the upper drive wheel and several guide wheels. Material enters between the upper and lower conveyor belts via the lower conveyor belt 42. The distance between the beginning of the upper conveyor belt and the lower conveyor belt should be adapted to the height of the material. Ideally, the beginning of the upper conveyor belt 41 should be slightly higher than the inclined material, so that the material can directly and quickly enter between the upper and lower conveyor belts 42 under the drive of the lower conveyor belt 42, resulting in more stable conveying. To meet the needs of materials of different specifications, the upper conveying component also includes a movable plate 48 for adjusting the height of the beginning. The frame 5 includes a vertically arranged mounting plate 52 (see attached figure). Figure 3 The mounting plate is provided with a guide groove for the vertical oblique movement of the movable plate 48. When the movable plate 48 moves obliquely downward, the starting height of the upper conveyor belt 41 decreases; conversely, when the movable plate 48 moves obliquely upward, the starting height of the upper conveyor belt 41 increases, which is suitable for longer materials. The movable plate 48 is provided with teeth 47, and the mounting plate 52 is provided with a gear 45. The gear 45 meshes with the teeth 47 on the movable plate 48. The rotation of the gear 45 drives the movable plate 48 to move, which facilitates the adjustment of the movable plate 48 and improves the accuracy of the adjustment. The guide wheels include a starting guide wheel 44, an ending guide wheel 410, a compensating guide wheel 49, and a fixed guide wheel 46. The upper conveyor belt 41 passes sequentially around the starting guide wheel 44, the compensating guide wheel 49, the fixed guide wheel 46, and the ending guide wheel 410. The fixed guide wheel 46 and the ending guide wheel 410 are mounted on the mounting plate 52, while the compensating guide wheel 49, the starting guide wheel 44, and the material distribution baffle 413 are mounted on the movable plate 48. When the movable plate 48 moves, the starting guide wheel and the compensating guide wheel move accordingly, while the fixed guide wheel and the ending guide wheel remain unchanged. This allows the starting guide wheel to move while maintaining tension on the upper conveyor belt 41, making adjustment convenient. Simultaneously, the material distribution baffle 413 moves synchronously, and its height is adjusted accordingly.

[0022] The lower conveying component also includes a lower drive wheel and a roller assembly. The roller assembly includes several rollers 43. The lower drive wheel and several rollers 43 are rotatably mounted on the frame 5. The lower conveyor belt 42 is disposed on the lower drive wheel and the roller assembly. The roller assembly supports the conveying section of the lower conveyor belt 42. The upper conveyor belt 41 is pressed against the conveying section of the lower conveyor belt 42, ensuring stable clamping and conveying. The upper drive wheel and the lower drive wheel are drive wheels, which are easier to control.

[0023] The material distribution component also includes a connecting plate 412 and an adjusting assembly for adjusting the feed gap. The connecting plate 412 is connected to the movable plate 48. The conveying length of the lower conveying component between the material distribution baffle 413 and the feeding conveying device 3 matches the length of the material. Adjusting the position of the movable plate 48 adjusts the position of the material distribution baffle 413, and simultaneously adjusts the feed gap according to the thickness of the material. The adjusting assembly includes a first swing arm 415, a second swing arm 417, a cam 414, and a spring 416. One end of both the first swing arm 415 and the second swing arm 417 is rotatably mounted on the connecting plate 412, and the other end is rotatably connected to the material distribution baffle 413. The cam 414 is rotatably mounted on the connecting plate 412. The two ends of the spring 416 are respectively connected to the connecting plate 412 and one of the swing arms, and the force of the spring 416 keeps the first swing arm 415 pressed against the cam. The first swing arm 415 and the second swing arm 417 are swung by rotating the cam, thereby adjusting the feeding gap between the material distribution baffle 413 and the lower conveyor belt 42.

[0024] The feeding mechanism of the box packer includes an information acquisition component that detects whether there is material at the connection between the material distribution conveyor 4 and the feeding conveyor 3. The information acquisition component includes a spring sheet 35 and a sensor 34. The end of the spring sheet 35 furthest from the material distribution baffle 413 is the mounting end, and the other end is the movable end. The mounting end is mounted on the connecting plate 412, and the movable end applies downward elastic force. The sensor 34 collects information from the spring sheet 35. The sensor 34, the material distribution conveyor 4, and the feeding conveyor 3 are all electrically connected to the controller. If material accumulates at the end of the feeding conveyor 3, the material supports the movable end of the spring sheet 35, and the sensor collects the spring sheet information. When there is no material at the end of the feeding conveyor 3, the movable end of the spring sheet 35 droops, the sensor does not collect spring sheet information, and the material distribution conveyor 4 stops conveying. When material is fed in, the material pushes the movable end of the spring sheet 35 upward, the sensor 34 collects the spring sheet 35 information, and the material distribution conveyor 4 pneumatically feeds the material.

[0025] The feeding conveyor 3 also includes a pallet 33, which is positioned in front of the conveyor belt and connected to both the conveyor belt and the lower conveyor belt 42. The conveyor belt feeds material onto the pallet, where it accumulates. The material is then actively conveyed by the material distribution conveyor 4, allowing for better integration between the feeding conveyor 3 and the material distribution conveyor 4. The feeding conveyor 3 also includes an upper baffle 32, positioned above the pallet and connected to a connecting plate 412. The area between the upper baffle 32 and the pallet 33 forms a material stacking zone. The upper baffle 32 has a clearance notch to allow space for the material distribution baffle 413 and the spring clip 35.

[0026] The frame 5 also includes a crossbeam 51, on which the mounting plate is mounted. The upper conveying component and the lower conveying component are mounted on the mounting plate, and the lateral position of the mounting plate on the crossbeam is adjustable. The lateral position of the material dispensing conveyor 4 on the frame 5 is adjustable, allowing for better integration with the box gluing machine and the feeding conveyor 3.

[0027] The working principle of the preferred embodiment is further explained below with reference to the accompanying drawings: Material is piled up in the material stacking area, and the material supports the spring sheet 35. The material in front of the material stacking area is against the lower conveyor belt 42. The lower conveyor belt 42 conveys the material upward. The material distribution baffle 413 blocks the material behind from above, so that the material in front enters between the upper conveyor belt 41 and the lower conveyor belt 42 first. The conveyor belt 31 continues to convey the material forward, so that the material is against the lower conveyor belt. As the material in front is sent away, the material behind continues to enter, so that the material enters between the upper and lower conveyor belts in an orderly manner and is conveyed upward by the two, in preparation for the subsequent top-down boxing.
