When this mechanism is working, when the cut workpiece is transported to the bottom of the push rod, the eccentric wheel presses the push rod to discharge the waste, which changes the situation of manual waste discharge, saves manpower, and improves production efficiency. A waste collection device is provided under the table top to realize automatic collection of waste.

[0003] Although the waste discharge mechanism of the die-cutting machine in the above-mentioned prior art can realize automatic waste discharge, it has the following defects during use: first, the ejector rod of the waste removal mechanism needs to be strictly synchronized with the running speed of the workpiece.

For example, if it is less than 4mm, it is difficult to implement with a too thin ejector rod. Summary of the invention

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] See also Figures 1 to 5 , Figures 1 to 5Disclosed is a first embodiment of a micro-hole waste discharge module for a die-cutting full-through process, a micro-hole waste discharge module for a die-cutting full-through process, comprising a fixed frame 1 provided with a pressure rod placement position 10, a pressure rod assembly 2, and a pressure assembly 3. In this embodiment, the pressure rod assembly 2 and the pressure assembly 3 are each a group, and the pressure rod assembly 2 comprises a pressure rod 21 arranged at the pressure rod placement position 10 and a combined bearing 22 installed at the bottom of the first end of the pressure rod 21, the first end of the pressure rod 21 is connected to the fixed frame 1, specifically, in the present invention, the first end of the pressure rod 21 is connected to the fixed frame 1 through a connecting member 11, and the connecting member 11 here is a screw, and the second end of the pressure rod 21 is rotatably connected to the fixed frame 1, specifically, in this embodiment, the second end of the pressure rod 21 is rotatably connected to the fixed frame 1 through a fixing pin 4. In the present invention, the pressure assembly 3 includes a pressure screw 30, a first magnet 31 and a second magnet 32 ​​with mutually exclusive polarities, the first magnet 31 is located at the upper part of the first end of the pressure rod 21, the second magnet 32 ​​is located at the lower end of the pressure screw 30, and the second magnet 32 ​​is located directly above the first magnet 31, the pressure screw 30 contacts the second magnet 32 ​​to control the distance between the first magnet 31 and the second magnet 32, thereby controlling the downward pressure on the pressure rod 21, that is, in the present invention, by adjusting the pressure screw 30, the distance between the first magnet 31 and the second magnet 32 ​​can be controlled, thereby controlling the downward pressure on the pressure rod 21. In the present invention, the polarities of the first magnet 31 and the second magnet 32 ​​are repulsive, which will give downward pressure to the first end of the pressure rod 21. Since the second end of the pressure rod 21 is rotatably connected to the fixing frame 1 through the fixing pin 4, the first end of the pressure rod 21 will move downward in a counterclockwise direction with the fixing pin 4 at the second end as the axis point, so that the combined bearing 22 will move a certain displacement as the first end of the pressure rod 21 moves downward. When the material passes through here, the downward combined bearing 22 will act on the material, thereby achieving the purpose of waste discharge; in the present invention, firstly, a magnetic mechanism is used as a pressure component to provide a downward force on the pressure rod 21, which is more stable, has no risk of jamming, and has no wear. The present invention does not require a power source, is energy-saving and environmentally friendly, and has a lower cost of use. Secondly, the combined bearing 22 used in the present invention allows for smoother, less jamming and wear-free operation, and can reach the die-cutting operating speed, thereby being synchronized with the die-cutting speed and being more efficient. Furthermore, in the present invention, the size of the combined bearing 22 can be very small, that is, it can be selected based on existing bearings on the market. Therefore, compared to the prior art, the present invention is suitable for online waste discharge of tiny holes in die-cut products.

[0027] In the present invention, preferably, a bearing mounting position 23 is provided at the first end of the pressure rod 21, the combined bearing 22 is located at the bearing mounting position 23, the top wall of the bearing mounting position 23 is an inwardly inclined slope, the connecting member 11 is inserted from the fixing frame 1 and abuts against the top wall of the bearing mounting position 23. In this embodiment, the connecting member 11 is a screw, and the connecting member 11 contacts the top wall of the bearing mounting position 23 (the top wall is an inwardly inclined slope), thereby limiting the downward pressing height of the pressure rod 21, thereby controlling the downward displacement of the combined bearing 22.

[0028] In the present invention, preferably, the combined bearing 22 includes a first bearing 221 and a second bearing 222, and the second bearing 222 is integrally sleeved into the inner ring of the first bearing 221. In the present invention, the advantage of using a double bearing sleeve is that the single speed of the bearing can be shared under extremely high-speed rotation, reducing wear and tear, thereby extending the service life of the bearing.

[0029] In the present invention, preferably, a first mounting cavity 210 for accommodating a first magnet 31 is provided at the upper portion of the first end of the pressure rod 21, and a second mounting cavity 15 is provided at the fixing frame 1 corresponding to the upper portion of the first mounting cavity 210, and the pressure screw 30 and the second magnet 32 ​​are located in the second mounting cavity 15. The purpose of setting the first mounting cavity 210 and the second mounting cavity 15 is that when the magnet and the pressure screw 30 are damaged, they can be replaced, which makes disassembly and assembly more convenient.

[0030] The present invention can also be set as a second embodiment (such as Figure 6 and Figure 7 As shown), the second embodiment is substantially the same as the first embodiment, the difference being that the pressure assembly 3 and the pressure rod assembly 2 are both in three groups, and the pressure rods 21 of each group of pressure rod assemblies 2 are separated on the fixing pin 4 by a separation gasket 5. Of course, the pressure rod assemblies 2 can be in two or more groups, and the pressure assemblies 3 are equal in number to the pressure rod assemblies 2. Two or more groups of the pressure rod assemblies 2 are arranged in the pressure rod placement positions 10, and the pressure assemblies 3 are arranged corresponding to the pressure rod assemblies 2 (see the first embodiment for details). In this embodiment, the pressure assembly 3 is arranged corresponding to the pressure rod assembly 2, and each pressure rod assembly 2 is adjusted independently. The purpose of such arrangement is that multiple groups of combined bearings 22 can act on multiple materials at the same time for waste discharge, and the purpose of improving work efficiency can be achieved without increasing equipment, which is more efficient and has lower cost.

[0031] In the present invention, preferably, the fixing frame 1 is provided with at least two fixing holes 12, and the fixing holes 12 are used to fix the fixing frame 1. It also includes at least two fixing shafts 13 and two fastening screws 14.

One end of the suction pipe 942 is connected to the discharge end of the suction hopper 941, and the other end is connected to the collection container 943. The air inlet of the suction fan 944 is connected to the exhaust port of the suction hopper 941. The aggregate container 943 is connected, and the air outlet is connected to the exhaust pipe 945. When the present invention is in use, the sheet material 90 coming out of the die-cutting machine 92 is die-cut with many fully perforated positions. When it reaches the waste discharge module 93, the waste 95 is pressed down by the combined bearing 22 of the waste discharge module 93 and separated from the main body of the sheet material 90. Under the suction action of the suction fan 944, the waste 95 falls into the suction hopper 941, and then enters the aggregate container 943 through the suction pipe 942 and is collected by the aggregate container 943. The present invention has a clever structural design, is very simple to install, adjust and operate, has stable operation, high waste discharge efficiency, good effect, longer service life, can be mass-produced, and the waste discharge speed can also be synchronized with the speed of the die-cutting machine 92, which is very suitable for promotion and use.
