Description

Technical Field

[0001] This utility model relates to the field of packaging machinery transportation, and more specifically, to a separate feeding device. Background Technology

[0002] Corrugated cardboard is widely used as the main raw material for carton production due to its high mechanical strength and ability to withstand collisions and drops during handling.

[0003] In the production process of cardboard boxes, there are two feeding methods for equipment such as die-cutting machines or printing machines. One is the manual method, which requires one or two people to move the cardboard stacks (i.e., several cardboards stacked to a certain height) to the feeding table of the die-cutting machine or printing machine in batches. The other is the semi-automatic method, which uses a feeding machine to raise the entire stack of cardboard, and then the cardboard is manually delivered to the feeding table of the die-cutting machine or printing machine. The existing two feeding methods are not only inefficient, but also cannot separate the cardboards one by one, which greatly reduces the production efficiency of cardboard boxes.

[0004] Therefore, a separate feeding device is needed to solve the problems of low efficiency and poor separation accuracy of the existing feeding method. Utility Model Content

[0005] In view of this, the present invention proposes a separate feeding device, which aims to solve the problems of low efficiency and poor separation accuracy of the existing feeding method.

The limiting plate is located above the discharge port, and the bottom surface of the limiting plate is flush with the top surface of the discharge port. A square mounting groove is provided at the center of the bottom surface of the limiting plate.

[0017] A lever is disposed in the mounting groove, the bottom of the lever is slidably connected to the mounting groove, and the top of the lever extends out of the mounting groove;

[0018] A first telescopic rod is embedded in the mounting groove. One end of the first telescopic rod is connected to the inner side of the mounting groove, and the other end is connected to the outer side of the lever. The first telescopic rod is used to pull the lever to reciprocate in the mounting groove.

[0019] Furthermore, a second telescopic rod is correspondingly provided on the inner side surface of the two parallel side plates in the main housing, and a push plate is provided on the end face of the second telescopic rod. The push plate is used to adjust the position of the cardboard material.

[0020] Furthermore, the support column includes:

[0023] The vibrating column is a square column with a groove on the bottom surface. The vibrating column is sleeved on the sliding column, and the top surface of the vibrator is connected to the bottom surface of the groove of the vibrating column.

[0024] Furthermore, the vibrator and the vibrating column are fixedly connected by a flexible pad.

[0025] Furthermore, a flexible pressure sensor is laid on the bottom surface of the limiting plate, and the pressure sensor is used to determine whether the cardboard material has reached the fixed position.

[0026] Furthermore, a guide port is provided at the opening on the side of the discharge port away from the limiting plate. The guide port is a square box with openings at both ends, and the four inner sides of the guide port are flush with the four inner sides of the discharge port.

[0041] See Figure 1 As shown, this embodiment provides a separate feeding device, including:

[0042] The base 100 is a square platform used to support and fix the various components.

[0043] The main housing 200 is a groove-shaped structure with side openings, and is surrounded by three side plates 220. The side plate 220 perpendicular to the other two side plates 220 in the main housing 200 is provided with a discharge port 210. The main housing 200 is fixedly connected to the top surface of the base 100.

[0044] The separation unit 300 is located above the discharge port 210 and is fixedly connected to the inner side of the side plate 220 that is perpendicular to the other two side plates 220 in the main housing 200.

[0045] The lifting unit 400 is connected to the inner side of the side plate 220 that is perpendicular to the other two side plates 220 in the main housing 200. The lifting unit 400 is used to lift the cardboard material to a fixed height.

[0046] Two conveyor belts are provided, and the two conveyor belts are horizontally positioned on the top surface of the base 100, with one end of each conveyor belt close to the lifting unit 400.

[0047] Specifically, the width of the discharge port should be greater than the thickness of one layer of cardboard but less than the thickness of the cardboard on both sides.

[0048] Understandably, the entire stack of cardboard is transported to the lifting device via a conveyor belt, and then the lifting device raises the entire stack of cardboard to a fixed height. The separating unit 300 then separates the cardboard pieces one by one from the entire stack, achieving fully automatic separation of the entire stack of cardboard and greatly improving feeding efficiency.

[0049] See Figure 2 As shown, in some embodiments provided by this utility model, the lifting unit 400 includes:

[0050] Two electric slide rails 410 are provided. The two electric slide rails 410 are embedded vertically in the inner side of the side plate 220 that is perpendicular to the other two side plates 220 in the main housing 200. The two electric slide rails 410 extend along the top surface of the base 100 to below the discharge port 210.

[0051] Two support columns 420 are provided, and the two support columns 420 are slidably connected to two electric slide rails 410 respectively.

[0052] Specifically, the distance between the top of the electric slide rail 410 and the bottom of the discharge port 210 is equal to the width of the support column 420, so that when the support column 420 is raised to its maximum height by the electric slide rail 410, the top surface of the support column 420 is flush with the bottom surface of the discharge port 210.

[0053] Understandably, when the entire stack of cardboard is transported onto the support column 420, the electric slide rail 410 drives the support column 420 to move upward, thereby lifting the entire stack of cardboard.

[0054] See Figure 2-3 As shown, in some embodiments provided by this utility model, the separation unit 300 includes:

[0055] The limiting plate 310 is fixedly connected to the inner side of the side plate 220 that is perpendicular to the other two side plates 220 in the main housing 200. The limiting plate 310 is set above the discharge port 210, and the bottom surface of the limiting plate 310 is flush with the top surface of the discharge port 210. A square mounting groove is provided at the center of the bottom surface of the limiting plate 310.

[0056] A lever 320 is set in the mounting groove, with the bottom of the lever 320 slidably connected to the mounting groove and the top of the lever 320 extending out of the mounting groove;

[0057] The first telescopic rod 230 is embedded in the mounting groove. One end of the first telescopic rod 230 is connected to the inner side of the mounting groove, and the other end is connected to the outer side of the lever 320. The first telescopic rod 230 is used to pull the lever 320 to reciprocate in the mounting groove.

[0058] Specifically, the length of the part of the pusher block 320 extending out of the mounting groove should be less than the thickness of the cardboard to prevent peeling off multiple layers of cardboard at once.

[0059] Understandably, the bottom surface of the limiting plate 310 is flush with the top surface of the discharge port 210. When the topmost cardboard in the stack comes into contact with the bottom surface of the limiting plate 310, the lifting stops. At this time, the cardboard is located between the discharge port 210 and the pusher block 320. Then the pusher block 320 reciprocates and continuously pushes the cardboard to separate it.

[0060] See Figure 2 As shown, in some embodiments provided by this utility model, the inner surfaces of the two parallel side plates 220 in the main housing 200 are respectively provided with second telescopic rods 330, and the end faces of the second telescopic rods 330 are provided with push plates 240, which are used to adjust the position of the cardboard material.

[0061] Specifically, when the two second telescopic rods 330 reach their maximum extension distance, the distance between the two push plates 240 is the same as the length of the cardboard.

[0062] Understandably, when the entire stack of cardboard is transported to the support column 420, the second telescopic rod 330 extends to its maximum distance at the same time, so that the position of the entire stack of cardboard can correspond to the discharge port 210.

[0063] See Figure 4 As shown, in some embodiments provided by this utility model, the support column 420 includes:

[0064] The sliding column 421 is a square column, and the sliding column 421 is slidably connected to the electric slide rail 410.

[0065] Vibrator 422 is installed on the top surface of sliding column 421;

[0066] The vibrating column 423 is a square column with a groove on the bottom surface. The vibrating column 423 is sleeved on the sliding column 421, and the top surface of the vibrator 422 is connected to the bottom surface of the groove of the vibrating column 423.

[0067] The vibrator and the vibrating column 423 are fixedly connected by a flexible pad 424.

[0068] Specifically, the vibrating column 423 is sleeved on the sliding column 421. The vibrating column 423 and the sliding column 421 are connected only through the vibrator 422. The end of the vibrating column 423 near the electric slide rail 410 does not contact the electric slide rail 410.

[0069] Understandably, when a stack of cardboard is transported to the vibrating column 423, the vibrator 422 vibrates to prevent the cardboard pieces in contact from sticking together due to static electricity.

[0070] Understandably, the end of the vibration column 423 near the electric slide rail 410 does not contact the electric slide rail 410, effectively preventing vibration from being transmitted to the main housing 200.

[0071] Understandably, a flexible pad 424 is placed between the vibrator and the vibrating column 423 to transmit vibration, which solves the problem that the connection between the vibrator and the vibrating column 423 is easily damaged by vibration when they are rigidly connected.

[0072] See Figure 3 As shown, in some embodiments provided by this utility model, a flexible pressure sensor 340 is laid on the bottom surface of the limiting plate 310. The pressure sensor is used to determine whether the cardboard material has reached the fixed position.

[0073] Specifically, when the top layer of the cardboard in the stack comes into contact with the flexible pressure sensor 340, the flexible pressure sensor 340 detects pressure. At this time, the electric slide rail 410 immediately stops lifting. After the push block 320 separates the top layer of cardboard, the flexible pressure sensor 340 loses pressure, and the electric slide rail 410 continues to lift the stack of cardboard until it comes into contact with the pressure sensor. This process is repeated until the electric slide rail 410 continues to lift to the maximum distance.

[0074] See Figure 5 As shown, in some embodiments provided by this utility model, a guide port is provided at the opening on the side of the discharge port 210 away from the limiting plate 310. The guide port is a square box with openings at both ends, and the four inner sides of the guide port are flush with the four inner sides of the discharge port 210.

[0075] Specifically, the guide port is away from the opening end of the discharge port and

[0076] It is understandable that the paper feed tables of die-cutting machines or printing machines are connected.

[0077] Specifically, the guide port 250 ensures that the cardboard is accurately delivered to the paper feed table, preventing the cardboard from flying around or tilting.

[0078] See Figure 5As shown, in some embodiments provided by this utility model, a plurality of pulleys 251 are embedded on the inner bottom surface of the guide port. The rotation direction of the pulleys 251 is consistent with the movement direction of the cardboard, and the pulleys 251 are used to reduce the resistance of the cardboard movement.

[0079] Understandably, the design of pulley 251 significantly reduces the resistance to the movement of the cardboard, preventing excessive friction from damaging the cardboard.

[0080] See Figure 1 As shown, in some embodiments of this utility model, a motor is provided on the side of the conveyor belt away from the lifting unit 400, and the motor is used to provide power to the conveyor belt.

[0081] Specifically, the conveyor belt transports the entire stack of cardboard to the support column 420. Then, the vibrator 422 inside the support column 420 vibrates, breaking up the cardboard that is stuck together due to static electricity. Then, the second telescopic rod 330 extends, driving the push plate 240 to adjust the position of the entire stack of cardboard to correspond with the discharge port 210. Then, the electric slide rail 410 starts, driving the support column 420 and the entire stack of cardboard to rise. When the top layer of cardboard contacts the flexible pressure sensor 340 on the bottom surface of the limit plate 310, the electric slide rail 410 stops. Then, the first telescopic rod 230 drives the paddle block 320 to reciprocate, separating the top layer of cardboard from the discharge port 210. Then, the flexible pressure sensor 340 loses pressure, the electric slide rail 410 starts, and the cycle continues until the support column 420 rises to its maximum height, and all the cardboard is separated. The separated cardboard is transported to the paper conveying table through the guide port 250.

[0082] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
