Description

Technical Field

[0001] This utility model relates to a material receiving device, and more particularly to a material receiving device for die-cutting packaging box paper. Background Technology

[0002] Packaging paper is die-cut into packaging paper with certain creases by a die-cutting machine. In the subsequent packaging process, the packaging paper can be folded through the creases after die-cutting to form a three-dimensional packaging box with a certain shape. Since the die-cutting machine is generally a continuous automatic die-cutting machine, the die-cut packaging boxes need to be received by workers in a timely manner, and stacked and sorted before being sent to the box folding process to be folded into packaging boxes. Otherwise, the packaging paper will accumulate at the exit of the die-cutting machine. Therefore, in order to save labor costs, a receiving device corresponding to continuous automatic die-cutting needs to be designed at the exit of the packaging paper die-cutting machine so that the die-cut packaging paper with creases is automatically received and stacked together. Summary of the Invention

[0003] The purpose of this invention is to provide a packaging box paper die-cutting and receiving device to save on the problem of manual receiving of packaging box paper.

[0004] To achieve the above objectives, this utility model is implemented as follows: A packaging box paper die-cutting receiving device includes a feeding mechanism and a connected receiving mechanism. The receiving mechanism includes a receiving frame and two opposing swing plate mechanisms mounted on the receiving frame. Each swing plate mechanism includes a swing plate base. The bottom of the swing plate base is provided with a pair of protruding swing columns. The swing columns are connected to a row of swing plates via a rotating shaft. The swing plates form a lever system with a short side and a long side around the rotating shaft as the fulcrum. Multiple swing plates have connecting plates at their short side edges, so that multiple swing plates form a linkage system with the rotating shaft as the fulcrum. The upper part of the swing plate base is provided with a swing groove corresponding to the short side of the swing plates and the connecting plates. The bottom of the connecting plate is provided with a connecting end, and the connecting end is rotatably connected to a pull rope. The pull rope is connected to a counterweight. An electromagnet is installed on the bottom of the swing plate base in the direction away from the swing groove. The lower surface of the swing plate and the bottom surface of the swing plate form a flat magnetic attraction surface. The swing plate has an iron attraction area on the side of the swing plate surface corresponding to the position of the magnetic attraction surface and facing the magnetic attraction surface. When the electromagnet is energized, the torque of the swing plate in the short side direction is greater than the torque in the long side direction. The long side of the swing plate is magnetically attracted to the magnetic attraction surface on the swing plate seat, so that the long side of the swing plate remains horizontal and receives the packaging paper transmitted by the feeding mechanism. The swing plate seat also has an adjustment groove at its front end. A pair of fiber optic sensors are installed below the adjustment groove. The sensing direction of the fiber optic sensors is towards the packaging paper. Through the fiber optic sensors, the external controller disconnects the power supply of the electromagnet. The electromagnet loses its magnetism. Under the combined action of the swing plate's own weight and the weight of the packaging paper, the torque of the swing plate in the long side direction is greater than the torque in the short side direction. The swing plate opens downwards, allowing the packaging paper to fall into the receiving rack.

[0005] Furthermore, the weight of the hammer generates a torque that causes the pendulum to swing downwards at an angle β of 20° to 30°. During the downward swing of the pendulum, the inertial swing generates an angle θ of 60° to 70°, which fully opens the pair of pendulum mechanisms. When the electromagnet is energized, the torque generated by the weight on the short side of the swing plate and the attraction of the electromagnet on the swing plate make the torque of the swing plate in the short side greater than the torque in the long side, thus ensuring that the swing plate will not fall when receiving the packaging paper. When the packaging paper reaches the position of a pair of fiber optic sensors, the external controller disconnects the power supply to the electromagnet through the fiber optic sensors, causing the packaging paper to fall, thus facilitating the automatic reception and stacking of the packaging paper. When the packaging paper is unloaded, the swing plate first swings to the swing angle position β under the action of the weight. At the same time, the packaging paper impacts the swing plate with inertia after falling, and the swing plate continues to swing to the swing angle position θ before stopping completely. At this time, the swing plate is fully open, allowing the packaging paper to fall completely into the receiving frame. When the swing plate swings to the swing angle position θ and the packaging paper falls, the swing plate swings back to the swing angle position β under the pull of the weight.

[0006] Furthermore, the swing plate is an iron plate, and the hammer is an iron block, a lead block, or a copper block.

[0007] Furthermore, the swing plate is a plastic plate, and an iron magnetic block is integrally injection molded or installed on the swing plate surface on the side of the swing plate corresponding to the magnetic attraction surface and facing the magnetic attraction surface. The weight is a plastic block, a rubber block or an aluminum block.

[0008] Furthermore, the receiving rack has two sets of oppositely arranged inverted L-shaped fixing frames at its lower part, with an adjustment plate between the fixing frames, and a receiving frame is arranged in the space formed between the adjustment plates.

[0009] Furthermore, the fixing frame is provided with a first adjustment groove, and the adjustment plate is provided with a connecting plate corresponding to the fixing frame. The connecting plate is provided with a second adjustment groove corresponding to the first adjustment groove. The second adjustment groove and the first adjustment groove are fixedly and adjustablely by fixing screws. The spacing between the adjustment plates is adjusted and fixed by fixing screws, thereby facilitating the material receiving mechanism to adjust according to the size of the packaging box paper.

[0010] Furthermore, the feeding mechanism includes a transmission frame, with multiple transmission rollers rotatably mounted between the two sides of the transmission frame. A transmission belt is provided between the multiple transmission rollers for transmission connection. A motor is also coaxially connected to one of the transmission rollers at the end. After the packaging box paper is die-cut by the die-cutting machine, it is transported through the transmission belt on the transmission frame and sequentially and rhythmically transported to the receiving mechanism's shelf, thereby realizing the automatic receiving of the packaging box paper.

[0011] In this invention, packaging paper is conveyed to a receiving mechanism via a feeding mechanism. The packaging paper conveyed to the receiving mechanism continues to move under the continuous push of the packaging paper conveyed by the feeding mechanism. When the packaging paper on the receiving mechanism reaches a pair of fiber optic sensors of the swing plate mechanism, it indicates that the packaging paper has been conveyed to the predetermined position. The fiber optic sensors control the electromagnet to cut off the power momentarily through the controller, so that the swing plate swings downward under its own weight and the weight of the packaging paper, and the packaging paper on the swing plate falls into the receiving frame below under its own weight.

[0012] In this invention, when the electromagnet is energized, the torque generated by the weight on the short side of the pendulum and the attraction of the electromagnet on the pendulum cause the torque of the pendulum in the short side to be greater than the torque in the long side, thus ensuring that the pendulum will not fall when it supports the packaging box. When the electromagnet is de-energized, under the combined action of its own weight and the weight of the packaging box, the torque of the pendulum in the long side is greater than the torque in the short side, and the pendulum swings downward to open.

[0013] In this invention, the adjustment plates can be adjusted according to the size of the packaging paper, thereby placing a suitable receiving frame between the adjustment plates. Correspondingly, the fiber optic sensor adjusts its position according to the position of the receiving frame, thereby changing the position of the fiber optic sensor on the swing plate seat so that the packaging paper falls into the receiving frame at the appropriate position.

[0014] In this invention, the receiving device is connected to the back of the die-cutting machine's outlet, enabling the receiving and stacking of packaging paper after die-cutting, thus saving labor. Attached Figure Description

Detailed Implementation

[0024] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments. Example 1

[0025] A feeding device for packaging paper, as described in the following figure Figure 1 , Figure 2 The system includes a feeding mechanism 1 and a connected receiving mechanism. The feeding mechanism 1 includes a transmission frame 11, with multiple transmission rollers 12 rotatably mounted between the two sides of the transmission frame 11. A transmission belt 13 is provided between the multiple transmission rollers 12 for transmission connection. At one end of the transmission roller 12, a motor 14 is coaxially connected. The motor 14 moves the paper on the transmission belt 13. After the packaging box paper 2 is die-cut by the die-cutting machine, it is transmitted through the transmission belt 13 on the transmission frame 11 and sequentially and rhythmically to the receiving mechanism.

[0026] Reference Figure 2 , Figure 3The receiving mechanism includes a receiving frame 4 and two opposing swing plate mechanisms 3 mounted on the receiving frame 4. The lower part of the receiving frame 4 is provided with two sets of opposing inverted L-shaped fixing frames 41. An adjusting plate 42 is provided between the fixing frames 41. A receiving frame 45 is provided in the space formed between the adjusting plates 42. The receiving frame 45 is inserted between the adjusting plates 42 to receive the falling packaging paper 2. A front baffle 44 is also provided on the inner side of the receiving frame 45 to further ensure that the stacked packaging paper 2 received by the receiving frame 45 will not fall over. The fixing frame 41 is provided with a first adjusting groove 411. The adjusting plate 42 is provided with a connecting plate 421 corresponding to the fixing frame 41. The connecting plate 421 is provided with a second adjusting groove 422 corresponding to the first adjusting groove 411. The second adjusting groove 422 and the first adjusting groove 411 are fixedly and adjustablely fixed by fixing screws 43. The fixing screws 43 are used to adjust and fix the distance between the adjusting plates 42, so as to facilitate the receiving mechanism to adjust according to the size of the packaging paper 2.

[0027] Reference Figures 2-3 , Figures 5-7The swing plate mechanism 3 includes a swing plate base 31. A pair of protruding swing columns 315 are provided at the bottom of the swing plate base 31. The swing columns 315 are connected to a row of swing plates 32 via a rotating shaft 34. The swing plates 32 form a lever system with a short side and a long side, using the rotating shaft 34 as a fulcrum. Multiple swing plates 32 are connected together at their short side edges by connecting plates 33, forming a linkage system with the rotating shaft 34 as the fulcrum. The upper part of the swing plate base 31 has a swing groove 311 corresponding to the short side of the swing plates 32 and the connecting plates 33. The bottom of the connecting plate 33 has a connecting end 331, which rotates... A pull rope 35 is connected to a counterweight 36. The swing plate 32 is made of iron, and the counterweight 36 is made of iron, lead, or copper. An electromagnet 37 is installed on the bottom of the swing plate base 31 on the side away from the swing groove 311. The lower surface of the electromagnet 37 and the bottom surface of the swing plate 32 form a flat magnetic attraction surface 313. When the electromagnet 37 is energized, the torque of the swing plate 32 in the short side direction is greater than the torque in the long side direction. The long side of the swing plate 32 is magnetically attracted and attached to the magnetic attraction surface 313 on the swing plate base 31, so that the long side of the swing plate 32 remains horizontal and receives the packaging paper 2 conveyed by the feeding mechanism 1. The front end of the swing plate base 31 is also provided with an adjustment groove 312. On the bottom surface of the swing plate base 31 located at the adjustment groove 312, there is also an installation groove 314. A pair of fiber optic sensors 5 are installed in the installation groove 314 and below the adjustment groove 312. The sensing direction of the fiber optic sensors 5 is towards the packaging paper 2. The fiber optic sensors 5 are adjusted and fixed according to the size of the packaging paper 2 and the receiving frame 45 by adjusting screws 6. The pair of fiber optic sensors 5 are used to sense the position of the front and rear ends of the packaging paper 2. When both the front and rear ends of the packaging paper 2 reach the fiber optic sensors 5, it indicates that the position of the packaging paper 2 has been delivered to the predetermined position. The fiber optic sensors 5 disconnect the power supply of the electromagnet 37 through the external controller. The electromagnet 37 loses its magnetism. Under the combined action of its own weight and the weight of the packaging paper 2, the torque of the swing plate 32 in the long side direction is greater than the torque in the short side direction. The swing plate 32 opens downward, allowing the packaging paper 2 to fall into the receiving frame 45 in the receiving rack 4.

[0028] Reference Figure 4In this embodiment, the torque generated by the weight of the counterweight 36 causes the pendulum plate 32 to swing downwards at an angle β of 20°~30°. During the downward swing of the pendulum plate 32, the inertial swing generates an angle θ of 60°~70°, causing the pair of pendulum plate mechanisms 3 to fully open. This is because, when the electromagnet 37 is energized, the torque generated by the counterweight 36 on the short side of the pendulum plate 32 and the attraction of the electromagnet 37 on the pendulum plate 32 make the torque of the pendulum plate 32 in the short side greater than the torque in the long side, thus ensuring that the pendulum plate 32 will not fall when it receives the packaging box paper 2. When the packaging box paper 2 reaches the position of the pair of fiber optic sensors 5, the external controller disconnects the power supply to the electromagnet 37 through the fiber optic sensors 5, causing the packaging box paper 2 to fall, thus facilitating the packaging box paper 2 to fall. Automatically received and stacked together, when the packaging paper 2 is unloaded, the swing plate 32 first swings to the swing angle position β under the action of the weight 36. At the same time, the packaging paper 2 impacts the swing plate 32 with inertia after falling. The swing plate 32 continues to swing to the swing angle position θ before stopping completely. At this time, the swing plate 32 is fully open, so that the packaging paper 2 can fall completely into the receiving frame 45. When the swing plate 32 swings to the swing angle position θ and the packaging paper 2 falls, the swing plate 32 swings back to the swing angle position β under the pull of the weight 36. At the same time, the electromagnet 37 is re-energized. The magnetism generated by the electromagnet 37 can further attract the swing plate 32, which is at the swing angle position β, to the horizontal surface, thereby realizing the cyclic process of the swing plate 32 receiving the packaging paper 2.

[0029] In this invention, the packaging paper 2 is fed from the feeding mechanism 1 to the receiving mechanism. In the transmission frame 11, the packaging paper 2 is sent from one end of the transmission frame 11 to the other end by a rotating transmission belt 13. After the packaging paper 2 reaches the receiving mechanism, the packaging paper 2 can continue to move a certain distance by being driven by the transmission belt 13. When the packaging paper 2 completely leaves the transmission belt 13, the packaging paper 2 can use the subsequent moving packaging paper 2 to push the previous packaging paper 2 to continue to move to the position between a pair of fiber optic sensors 5. Example 2

[0030] Same as in Example 1, except that the shelf 32 is a plastic plate, see reference. Figure 8 The pendulum 32 has an integrally injection-molded or installed iron magnetic block 38 on the side of the pendulum 32 facing the magnetic surface 313. Since the pendulum 32 is made of plastic, its weight becomes much lighter. Correspondingly, the weight 36 is made of a relatively light plastic block, rubber block or aluminum block. However, because the iron magnetic block 38 is set in the magnetic surface 313, the electromagnet 37 can attract the pendulum 32 well and achieve the same effect.

[0031] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
