Description

Technical Field

[0001] This utility model relates to a feeding structure for packaging machinery, specifically, to a feeding structure for packaging machinery. Background Technology

[0002] As the packaging industry continues to expand, companies are demanding increasingly stringent requirements for packaging efficiency and quality. Industry reports indicate that a significant increase in customer orders has prompted companies to urgently upgrade the automation level of their packaging machinery in order to achieve an efficient, stable, and precise feeding process and gain a competitive edge in the fierce market competition.

[0003] Existing packaging machinery uses simple mechanical conveying devices for feeding. However, during the feeding process, it is difficult to accurately control the position and conveying rhythm of the packaging boxes, often resulting in boxes piling up, colliding, or even falling. For example, some feeding equipment using a single conveyor belt cannot convey boxes normally when the size of the boxes is slightly different, requiring frequent stops for adjustment. On the other hand, some equipment with simple lifting functions has poor lifting structure stability, which can easily cause the boxes to shake and tip over during the lifting process, making it impossible to achieve stable and efficient feeding. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding structure for packaging machinery to solve the problem of the difficulty in controlling the precise feeding of packaging boxes in the existing technology.

[0005] To achieve the above objectives, this utility model provides a feeding structure for packaging machinery, including a base plate. Two symmetrically arranged support plates are fixedly connected to the upper side of the base plate. A conveyor belt is provided on the upper side of the base plate, and a packaging box is placed on the conveyor belt. The conveyor belt is used to transport the packaging box towards the support plates. A feeding device is provided on the inner wall of each of the two support plates. The feeding device is used to feed the packaging box. The feeding device includes a plurality of rotating rods fixedly connected between the side walls of the two support plates. The plurality of rotating rods are arranged in an array. Two receiving blocks are rotatably connected to each of the plurality of rotating rods. A moving device is provided on the upper side of the base plate. The moving device is used to transport the packaging box upward.

[0006] As a further improvement to this technical solution, the moving device includes a hydraulic cylinder fixedly connected to the upper side of the base plate. A push plate is fixedly connected to the upper end of the hydraulic cylinder. Two symmetrically arranged sleeves are fixedly connected to the upper side of the base plate, and the two sleeves are arranged on both sides of the hydraulic cylinder. A moving rod is slidably connected inside the two sleeves. Teeth are provided on the side wall of the moving rod. The upper end of the moving rod passes through the sleeve and is fixedly connected to the lower side of the push plate.

[0007] The push plate is moved upward by a hydraulic cylinder. The push plate is stable and continuously pushes the packaging box through the meshing transmission of the moving rod and gear.

[0008] As a further improvement to this technical solution, the lower end of the receiving block is arc-shaped, and several limiting rods are fixedly connected between the side walls of the support plate. The limiting rods are located near the side wall of the support plate and at the upper end of the receiving block.

[0009] As a further improvement to this technical solution, a placement groove is provided at the top of the receiving block away from the limiting rod. The placement groove is used to place the upper two ends of the packaging box. The distance between two adjacent placement grooves is adapted to the height of the packaging box, and the distance between each set of placement grooves is less than the length of the packaging box.

[0010] The pusher plate pushes the packaging box and the receiving block together. The rotating receiving block allows the packaging box to rise one by one in an orderly manner, and finally it is supported and protected by the placement slot. This process reduces manual operation, improves packaging efficiency, ensures stable and accurate feeding, and greatly improves the automation level of packaging machinery.

[0011] As a further improvement to this technical solution, a bracket is fixedly connected to the upper side of the base plate, a cylindrical rod is rotatably connected to the upper side of the bracket, gears are fixedly connected to both ends of the cylindrical rod, and a circular groove is opened on the side of the sleeve near the gear, and the gear meshes with the teeth.

[0012] As a further improvement to this technical solution, a connecting plate is fixedly connected between the two support plates. Two fixing plates are fixedly connected to the side of the connecting plate near the conveyor belt, and the two fixing plates are inclined. The distance between the two fixing plates is less than the length of the packaging box.

[0013] As a further improvement to this technical solution, a conveyor belt is provided on the side of the support plate away from the conveyor belt, the upper surface of the conveyor belt is flush with the uppermost placement groove, and an electric telescopic rod is fixedly connected to the side of the two support plates away from the conveyor belt, and a rectangular plate is fixedly connected to one end of the electric telescopic rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The packaging box carrying the material is transported to the inclined fixed plate by the conveyor belt, and then slides down to a specific position with the help of gravity. Then, the push plate is driven to move up by the hydraulic cylinder. The push plate is stable through the meshing transmission of the moving rod and gear, and the packaging box is continuously pushed. At the same time, the push plate pushes the packaging box to act on the receiving block. The rotation of the receiving block realizes that the packaging box rises in an orderly manner one by one, and is finally supported and protected by the placement slot. This process reduces manual operation, improves packaging efficiency, ensures stable and accurate feeding, and greatly improves the automation level of packaging machinery.

[0026] Example 1

[0027] Please see Figures 1-5 As shown, this embodiment provides a feeding structure for packaging machinery, including a base plate 1. Two symmetrically arranged support plates 11 are fixedly connected to the upper side of the base plate 1. A conveyor belt 13 is arranged on the upper side of the base plate 1, and a packaging box 12 is placed on the conveyor belt 13. The conveyor belt 13 is used to transport the packaging box 12 towards the support plates 11. A connecting plate 15 is fixedly connected between the two support plates 11. Two fixing plates 16 are fixedly connected to the side of the connecting plate 15 near the conveyor belt 13, and the two fixing plates 16 are inclined. The distance between the two fixing plates 16 is less than the length of the packaging box 12. When using this device, the material is placed on the packaging box 12, and then the packaging box 12 is placed on the conveyor belt 13. The conveyor belt 13 transports the packaging box 12 towards the fixing plates 16. The two ends of the packaging box 12 rest on the upper side of the fixing plates 16. Due to the inclined arrangement of the fixing plates 16, the two ends of the packaging box 12 slide downward with the inclined surface of the fixing plates 16, and the packaging box 12 slides to contact the connecting plate 15.

[0028] Please see Figure 3 and Figure 5 As shown, a moving device 3 is provided on the upper side of the base plate 1. The moving device 3 is used to convey the packaging box 12 upward. The moving device 3 includes a hydraulic cylinder 31 fixedly connected to the upper side of the base plate 1. A push plate 32 is fixedly connected to the upper end of the hydraulic cylinder 31. Two symmetrically arranged sleeves 33 are fixedly connected to the upper side of the base plate 1, and the two sleeves 33 are located on both sides of the hydraulic cylinder 31. A moving rod 34 is slidably connected inside the two sleeves 33. The side wall of the moving rod 34 is provided with teeth. The upper end of the moving rod 34 passes through the sleeve 33 and is fixedly connected to the lower side of the push plate 32. A bracket is fixedly connected to the upper side of the base plate 1. A cylindrical rod 35 is rotatably connected to the upper part of the bracket. Gears 36 are fixedly connected to both ends of the cylindrical rod 35. The sleeves 33 are close to A circular groove 37 is provided on one side of the gear 36. The gear 36 meshes with the teeth. When the packaging box 12 moves to the position of the fixed plate 16, the hydraulic cylinder 31 is activated to drive the push plate 32 to move upward. The push plate 32 pushes the packaging box 12 upward. When the push plate 32 moves, it drives the moving rod 34 to move inside the sleeve 33. The moving rod 34 meshes with the gear 36, thereby driving the gear 36 to rotate. Through the meshing between the moving rod 34 and the gear 36, the moving rod 34 can be synchronized when moving, thereby improving the stability of the push plate 32. This allows the push plate 32 to continuously convey the packaging box 12 upward, realizing automatic material feeding, reducing manual operation, and improving packaging efficiency.

[0029] Please see Figures 2-4As shown, both support plates 11 have a feeding device 2 on their inner walls. The feeding device 2 is used to feed the packaging box 12. The feeding device 2 includes several rotating rods 21 fixedly connected between the side walls of the two support plates 11. The several rotating rods 21 are arranged in an array. Two receiving blocks 22 are rotatably connected to each of the rotating rods 21. A placement groove 23 is opened at the end of the receiving block 22 away from the limiting rod 24 near the top. The placement groove 23 is used to place the upper two ends of the packaging box 12. The distance between two adjacent placement grooves 23 is adapted to the height of the packaging box 12. The distance between each set of placement grooves 23 is less than the length of the packaging box 12. The push plate 32 drives the packaging box 12. As the packaging box 12 moves upward, it first contacts the lower arc surface of the receiving block 22 and pushes the receiving block 22 to rotate. The rotation of the receiving block 22 pushes the packaging box 12, which was originally located on the receiving block 22, upward. The upward movement of the packaging box 12 will push the packaging box 12 located above it to move upward. The packaging box 12 moves upward until both ends of the packaging box 12 are placed on the placement groove 23. The placement groove 23 provides a certain degree of support and protection for the packaging box 12. By rotating the receiving block 22, the packaging boxes 12 are pushed upward in sequence, realizing the orderly and sequential feeding of the packaging boxes 12. This is conducive to improving the automation level and working efficiency of the packaging machinery and ensuring the stability and accuracy of the feeding process.

[0030] Please see Figure 3 and Figure 4 As shown, the lower end of the receiving block 22 is arc-shaped, and several limiting rods 24 are fixedly connected between the side walls of the support plate 11. The limiting rods 24 are located near the side wall of the support plate 11 and are located at the upper end of the receiving block 22. When the receiving block 22 rotates, when the packaging box 12 is placed on the placement groove 23, the receiving block 22 will rotate due to the weight of the packaging box 12. To avoid this situation, a limiting rod 24 is provided on the upper side of the receiving block 22. The limiting rod 24 restricts the position of the receiving block 22 and prevents the receiving block 22 from rotating in the opposite direction and failing to support the packaging box 12.

[0031] Please see Figure 1 and Figure 4 As shown, a conveyor belt 14 is provided on the side of the support plate 11 away from the conveyor belt 13. The upper surface of the conveyor belt 14 is flush with the uppermost placement groove 23. An electric telescopic rod 17 is fixedly connected to the side of the two support plates 11 away from the conveyor belt 14. A rectangular plate 18 is fixedly connected to one end of the electric telescopic rod 17. When the packaging box 12 moves to the top, the uppermost packaging box 12 does not contact the receiving block 22. At this time, the electric telescopic rod 17 is activated to drive the rectangular plate 18 to move. The movement of the rectangular plate 18 pushes the uppermost packaging box 12 onto the conveyor belt 14 for transport.

[0032] In this embodiment, the feeding structure of the packaging machinery, when in use, places the material onto the packaging box 12, then places the packaging box 12 onto the conveyor belt 13. The conveyor belt 13 transports the packaging box 12 onto the fixed plate 16. Both ends of the packaging box 12 rest on the upper side of the fixed plate 16. Due to the inclined setting of the fixed plate 16, both ends of the packaging box 12 slide downwards along the inclined surface of the fixed plate 16. When the packaging box 12 slides to contact the connecting plate 15 and moves to the position of the fixed plate 16, the hydraulic cylinder 31 is activated to drive the push plate. As the push plate 32 moves upward, it pushes the packaging box 12 upward. When the push plate 32 moves, it drives the moving rod 34 to move within the sleeve 33. The moving rod 34 meshes with the gear 36, thereby driving the gear 36 to rotate. Through the meshing between the moving rod 34 and the gear 36, the moving rod 34 can be synchronized during movement, thus improving the stability of the push plate 32. This allows the push plate 32 to continuously convey the packaging box 12 upward, realizing automatic material feeding, reducing manual operation, and improving packaging efficiency.

[0033] The push plate 32 drives the packaging box 12 to move upward. When the packaging box 12 moves, it first contacts the lower arc surface of the receiving block 22 and pushes the receiving block 22 to rotate. The rotation of the receiving block 22 pushes the packaging box 12, which was originally located on the receiving block 22, upward. The upward movement of the packaging box 12 will push the packaging box 12 located above it to move upward. The packaging box 12 moves upward until both ends of the packaging box 12 are placed on the placement groove 23. The placement groove 23 provides a certain support and protection for the packaging box 12. By rotating the receiving block 22, the packaging boxes 12 are pushed upward in sequence, realizing the orderly feeding of the packaging boxes 12 one by one. This is conducive to improving the automation level and working efficiency of the packaging machinery and ensuring the stability and accuracy of the feeding process.
