Description

Technical Field

[0001] The utility model relates to the technical field of flat die-cutting machines, in particular to a stable paper feeding mechanism of a full-automatic flat die-cutting machine with a lower suction cup for feeding paper. Background Art

[0002] The platen and the pressing mechanism of the flat die-cutting machine are both in the shape of a flat plate. When the plane of the platen and the pressing plate are in a vertical position, it is a vertical flat die-cutting machine. When the die-cutting machine is working, the pressing plate is pressed against the plate through transmission to apply pressure to the platen. The pressing plate can be divided into two categories according to different movement trajectories: one is that the pressing plate swings around the fixed hinge, so at the moment of starting the die-cutting, there is a certain inclination angle between the working surface of the pressing plate and the die-cutting plate surface, so that the die-cutting plate cuts into the lower part of the cardboard earlier. When the die-cutting machine with the other pressing plate movement mechanism is working, the pressing plate is driven by the connecting rod and first swings on the flat guide rail of the machine base with the cylindrical roller as the fulcrum. When the working surface of the pressing plate is turned from the tilt to the position parallel to the die-cutting plate, it is then pressed parallel to the die-cutting plate in a translational manner.

[0003] The existing flat-bed die-cutter uses a top suction cup to feed paper. This has a long stroke, unstable operation, and requires an auxiliary device to always push the cardboard raw material upward. In this way, reloading can only be done after a batch of cardboard raw materials has been delivered, resulting in a time gap in the flat-bed die-cutter when feeding paper, reducing the paper feeding efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing flat die-cutter adopts a top suction cup to feed paper, so the top suction cup has a long stroke, unstable operation, and requires an auxiliary device to always push the paperboard raw material upward. In this way, reloading can only be performed after a batch of paperboard raw materials are delivered, resulting in a time gap when the flat die-cutter is feeding paper, thereby reducing the paper feeding efficiency.

[0005] In order to solve the above technical problems, the technical solution of the utility model is a stable paper feeding mechanism of a fully automatic lower suction cup paper feeding flat die-cutting machine, comprising a load-bearing base and a material storage rack, the material storage rack is installed on the upper wall of the load-bearing base, a number of structural reinforcement ribs are connected between the load-bearing base and the material storage rack, a number of cardboard raw materials are stored inside the material storage rack, a guide structure is installed on the upper wall of the load-bearing base, an auxiliary structure is installed in the guide structure, and a paper feeding structure is installed in the guide structure.

[0006] As a further solution of the utility model: the guide structure includes: two guide plates, two support frames, two slide grooves, an auxiliary positioning frame and an infrared emitter; the two guide plates are respectively installed on the upper wall of the load-bearing base, the two support frames are respectively installed on the front wall of the load-bearing base, the two slide grooves are respectively opened on the inner wall surfaces of the two support frames, the auxiliary positioning frame is installed on the front wall surface of the storage rack, and the infrared emitter is installed on the lower wall surface of the auxiliary positioning frame.

[0007] As a further solution of the utility model: the auxiliary structure includes: a cardboard pushing block, a connecting hydraulic rod, two limit frames and two cylinder connecting rods; the cardboard pushing block is installed on the inner wall surfaces of the two guide plates, the connecting hydraulic rod is connected to the rear wall surface of the cardboard pushing block, the two limit frames are respectively installed on the side wall surfaces of the two support frames, and the two cylinder connecting rods are respectively connected to the outer wall surfaces of the two limit frames.

[0008] As a further solution of the utility model: the paper feeding structure includes: two sliders, a conveying platform and a plurality of suction cups; the two sliders are respectively installed on the inner wall surfaces of the two slide grooves, the conveying platform is installed on the inner wall surfaces of the two sliders, and the plurality of suction cups are respectively installed on the upper wall surface of the conveying platform.

[0009] As a further solution of the utility model: an infrared receiver is installed on the inner wall surface of the material storage rack, and the infrared receiver is connected to the infrared transmitter.

[0010] As a further solution of the utility model: protective pads are respectively installed on the inner wall surfaces of the two limit frames.

[0011] As a further solution of the utility model: a plurality of the suction cups are evenly distributed on the conveying platform.

[0012] The utility model adopts the above technical solution, and has the following advantages compared with the prior art:

[0013] The material storage rack cooperates with the infrared transmitter and the infrared receiver, and utilizes gravity to make the cardboard raw material descend along the material storage rack. When the signal emitted by the infrared transmitter is not blocked by the cardboard raw material, it can be received by the infrared receiver. The infrared receiver controls the alarm system to send a signal to the staff, reminding the operator to feed the material into the material storage rack again, and at the same time sends a signal to the control system connected to the hydraulic rod to run again. After the operator feeds the material again, the signal emitted by the infrared transmitter is blocked by the cardboard raw material again, and the receiver sends a signal of cyclic operation to the control system connected to the hydraulic rod, which solves the problem that the existing flat-bed die-cutting machine needs auxiliary devices to always push the cardboard raw material upwards, so that reloading can only be performed after a batch of cardboard raw materials is delivered, resulting in a time gap in the flat-bed die-cutting machine when feeding paper, thereby reducing the paper feeding efficiency.

[0014] The two cylinder connecting rods respectively drive the two limit frames to slightly clamp the cardboard materials on the two support frames to complete the limit and prevent the cardboard materials on the two support frames from being scattered. Then, a number of suction cups absorb the cardboard materials at the lower ends of the two support frames. The conveyor table drives the two sliders to move repeatedly along the two slide grooves under the action of the linear motor. When moving to the outermost end, the suction cups release the suction force. At this time, the cardboard materials can fall off from the suction cups to complete the paper feeding work, which solves the problem that the existing flat-bed die-cutting machine uses the top suction cup for paper feeding, so that the top suction cup has a long stroke and unstable operation.

In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0022] See also Figure 2 The guide structure includes: two guide plates 5, two support frames 6, two slide grooves 7, an auxiliary positioning frame 8 and an infrared emitter 9; the two guide plates 5 are respectively installed on the upper wall of the load-bearing base 1, the two support frames 6 are respectively installed on the front wall of the load-bearing base 1, the two slide grooves 7 are respectively opened on the inner wall surfaces of the two support frames 6, the auxiliary positioning frame 8 is installed on the front wall surface of the storage rack 2, and the infrared emitter 9 is installed on the lower wall surface of the auxiliary positioning frame 8.

[0023] See also Figure 2 An infrared receiver 17 is installed on the inner wall of the material storage rack 2, and the infrared receiver 17 is connected to the infrared transmitter 9. In this embodiment, the infrared receiver 17 controls the alarm system to send a signal to the staff to remind the operator to feed the material storage rack 2 again, and at the same time sends a signal to the control system connected to the hydraulic rod 11 to run again.

[0024] In this embodiment, the material storage rack 2 cooperates with the infrared transmitter 9 and the infrared receiver 17, and gravity is used to make the cardboard raw material 4 descend along the material storage rack 2. When the signal emitted by the infrared transmitter 9 is not blocked by the cardboard raw material 4, it can be received by the infrared receiver 17. The infrared receiver 17 controls the alarm system to send a signal to the staff to remind the operator to feed the material into the material storage rack 2 again, and at the same time sends a signal to the control system connected to the hydraulic rod 11 to run again. After the operator feeds again, the signal emitted by the infrared transmitter 9 is blocked by the cardboard raw material 4 again, and the receiver 17 sends a signal of circulating operation to the control system connected to the hydraulic rod 11.

[0025] Specifically, the operator puts a number of cardboard raw materials 4 into the storage rack 2, and then starts to feed the paper. As the paper feeding proceeds, the number of cardboard raw materials 4 gradually descends along the storage rack 2 due to gravity. When the cardboard raw materials 4 are lower than the position of the infrared transmitter 9, the signal emitted by the infrared transmitter 9 is not blocked by the cardboard raw materials 4 and can be received by the infrared receiver 17. The infrared receiver 17 controls the alarm system to send a signal to the staff to remind the operator to feed the material into the storage rack 2 again, and at the same time sends a signal to the control system connected to the hydraulic rod 11 to run again. After the operator feeds the material again, the signal emitted by the infrared transmitter 9 is blocked by the cardboard raw materials 4 again, and the receiver 17 sends a signal of circulating operation to the control system connected to the hydraulic rod 11.

[0026] Example 2, please refer to Figure 3 The auxiliary structure includes: a cardboard pushing block 10, a connecting hydraulic rod 11, two limiting frames 12 and two cylinder connecting rods 13; the cardboard pushing block 10 is installed on the inner wall surface of the two guide plates 5, the connecting hydraulic rod 11 is connected to the rear wall surface of the cardboard pushing block 10, the two limiting frames 12 are respectively installed on the side wall surfaces of the two supporting frames 6, and the two cylinder connecting rods 13 are respectively connected to the outer wall surfaces of the two limiting frames 12.

[0027] See also Figure 4 The paper feeding structure includes: two sliders 14, a conveying platform 15 and a plurality of suction cups 16; the two sliders 14 are respectively installed on the inner wall surfaces of the two slide grooves 7, the conveying platform 15 is installed on the inner wall surfaces of the two sliders 14, and the plurality of suction cups 16 are respectively installed on the upper wall surfaces of the conveying platform 15.

[0028] See also Figure 3 The inner wall surfaces of the two limiting frames 12 are respectively installed with protective pads 18. In this embodiment, the protective pads 18 can prevent the two limiting frames 12 from damaging the paperboard raw material 4.

[0029] See also Figure 4 , a plurality of suction cups 16 are evenly distributed on the conveying platform 15 , and in this embodiment, uniform force is achieved.

[0030] In this embodiment, the hydraulic rod 11 is connected to drive the cardboard pushing block 10 to push the lower part of the cardboard raw material 4 in the storage rack 2 onto the two support frames 6 along the two guide plates 5, and then the hydraulic rod 11 is connected to drive the cardboard pushing block 10 to reset. When the cardboard pushing block 10 is reset, the remaining cardboard raw material 4 in the storage rack 2 falls along the storage rack 2 onto the load-bearing base 1. As the cardboard pushing block 10 is reset, the two cylinder connecting rods 13 respectively drive the two limiting frames 12 to slightly clamp the cardboard raw materials 4 on the two support frames 6 to complete the limiting.

[0031] Specifically, the hydraulic rod 11 is connected to drive the cardboard push block 10 to push the lower part of the cardboard raw material 4 in the storage rack 2 onto the two support racks 6 along the two guide plates 5, and then the hydraulic rod 11 is connected to drive the cardboard push block 10 to reset. When the cardboard push block 10 is reset, the remaining cardboard raw material 4 in the storage rack 2 falls on the load-bearing base 1 along the storage rack 2. As the cardboard push block 10 is reset, the two cylinder connecting rods 13 respectively drive the two limiting racks 12 to slightly clamp the cardboard raw material 4 on the two support racks 6 to complete the limiting and prevent the cardboard raw material 4 on the two support racks 6 from being scattered. Then, a plurality of suction cups 16 adsorb the cardboard raw material 4 at the lower end of the two support racks 6. The conveying platform 15 drives the two sliders 14 to move repeatedly along the two slide grooves 7 under the action of the linear motor. When moving to the outermost end, the plurality of suction cups 16 release the suction force. At this time, the cardboard raw material 4 can fall off from the plurality of suction cups 16 to complete the paper feeding work. A baffle can be set in front of the two limiting racks 12 to limit the position of the cardboard raw material 4 to prevent the cardboard raw material 4 from falling off from the two limiting racks 12.
