[0046] This embodiment provides a technical solution: a die-cutting mechanism of a die-cutting machine, such as Figure 1-9 As shown, it includes a die-cutting frame 1, a power seat 2 and a lower template 3. The lower template 3 is connected to the power seat 2, and the power seat 2 is fixed on the die-cutting frame 1 to provide lifting and lowering of the lower template 3.

[0048] A die-cutting position is formed between the lower template 3 and the upper template 5. When the lower template 3 moves up and down, the die-cutting position gradually shrinks or increases, that is, gas enters or overflows the die-cutting position;

[0049] Among them, since two surfaces of the lower template 3 and the upper template 5 are fixed or blocked with the die-cutting frame 1 during die-cutting, the increase or decrease of the die-cutting position during die-cutting will affect the air flow in the die-cutting position, and the air flow direction at this time is toward the other two side surfaces.

[0050] Optionally, the fixed seat 4 includes a hollow table 41 and a partition plate 42. The hollow table 41 is fixed on the die-cutting frame 1. Two partition plates 42 are provided and fixed inside the hollow table 41. The cavity between the two partition plates 42 is combined with the hollow table 41 to form a channel cavity. The partition plate 42 can also enhance the structural strength of the hollow table 41.

[0051] Optionally, the upper template 5 includes a mother mold 51, a sinking groove 52 and a clamping rod 53. The mother mold 51 is movably connected to the lower side of the hollow platform 41. The sinking groove 52 is opened on the lower side of the mother mold 51. The clamping rod 53 is arranged in the sinking groove 52. An electric control component is arranged on the upper side of the mother mold 51.

[0052] The active connection between the mother mold 51 and the hollow table 41 is detachable, and the upper mold plate 5 can be separated from the fixing seat 4 to replace the cutting mold 6 on the upper mold plate 5; this embodiment provides an optional disassembly scheme: a track groove is provided on the opposite side of the mother mold 51, and a track block is processed on the hollow table 41, and the track block slides with the track groove; a locking structure is also provided between the mother mold 51 and the hollow table 41 for locking and fixing the two. In this embodiment, two clamping rods 53 are provided to clamp, restrict and fix the cutting mold 6; the connection between the clamping rod 53 and the mother mold 51 adopts the existing bolt fixing method.

[0053] The electric control component includes a node member and a conductive wire 57. The mother mold 51 is provided with a plurality of through slots. The node members are correspondingly arranged in the plurality of through slots and the two ends thereof are flush with the mother mold 51.

[0054] Among them, the number of through grooves in this embodiment is set to four, and distributed at the four corners of the mother mold 51; when the two ends of the node piece are set flush with the mother mold 51, it can be ensured that the mother mold 51 and the node piece can contact the knife mold 6 on the same plane.

[0055] Each node part includes an injection molded part 54 and two conductive posts 55 fixed thereto. One end of the conductive post 55 close to the fixing seat 4 extends to the outer ring of the injection molded part 54, and the other end of the conductive post 55 is flush with the end surface of the injection molded part 54. Multiple node parts are sequentially connected by conductive wires 57 to form a string. One of the conductive posts 55 of the two node parts located at the head and the tail is connected to one end of the conductive wire 57, and the two ends of the conductive wire 57 between two adjacent node parts are respectively connected to one of the conductive posts 55 on the node part.

[0056] Furthermore, a wire sinking groove 56 is provided on the upper side of the mother mold 51 for submerging the conductive wire 57 in the mother mold 51 , so that the mother mold 51 can be kept from protruding and will not be hindered when the mother mold 51 and the hollow platform 41 are installed.

[0057] The end faces of the injection molded part 54 and the mother mold 51 are flush, the injection molded part 54 is made of insulating material, and the conductive pillars 55 fixed together on the injection molded part 54 isolate the two through the injection molded part 54; one end of the injection molded part 54 extends to the periphery of the injection molded part 54 for connection and fixation with the conductive wire 57, and an insulating layer is provided on the periphery of the conductive wire 57 to avoid conduction with the mother mold 51. In this embodiment, the conductive wire 57 is provided with five parts, and four node parts are connected in sequence through the conductive wire 57 to form a string.

[0058] The knife die 6 includes a knife plate 61 and a conductive sheet 62. A plurality of conductive sheets 62 are arranged and distributed on the knife plate 61.

[0059] Furthermore, the blade 61 protrudes from the lower side of the mother mold 51, so that during die cutting, the blade 61 can completely die cut the material to avoid interference from the mother mold 51. The position of the conductive sheet 62 corresponds to the position of the injection molded part 54, and one end of the conductive sheet 62 is flush with one side of the blade 61. In this embodiment, the number of the conductive sheets 62 and the number of the injection molded parts 54 are both four, and in order to maintain insulation, the conductive sheet 62 is submerged in the projection of the injection molded part 54.

[0060] The fixing seat 4 is provided with an alarm component 7 and a dust removal component 8, and the alarm component 7 and the conductive sheet 62 are provided in equal amounts;

[0061] Optionally, the alarm component 7 includes a contact structure and an alarm structure; the contact structure includes a column shell 71 fixed to the bottom of the hollow platform 41, and two conductive springs 72 are installed on the column shell 71, and the two conductive springs 72 are in contact with the two conductive columns 55 on the node member;

[0062] The alarm structure includes a support rod 73 fixed on the hollow platform 41, an alarm 74 is fixed at one end of the support rod 73, and the positive and negative terminals of the alarm 74 are correspondingly connected to the two conductive springs 72 through wires.

[0063] When the conductive sheets 62 are all in contact with the upper template 5, the alarm component 7 is powered off and closed; when one or more conductive sheets 62 are out of contact with the upper template 5, the alarm component 7 is powered on and works;

[0064] Among them, the lower side of the column shell 71 is provided with a through hole for extending the conductive spring 72. The column shell 71 is made of insulating material. The contact end of the conductive spring 72 and the conductive column 55 is provided with an arc-shaped protrusion, which can avoid scratching when the mother mold 51 and the hollow table 41 slide relative to each other. The support rod 73 extends out of the shielding range of the die cutting frame 1 to ensure that the operator can observe the alarm 74. The alarm 74 is a prior art, which has positive and negative poles connected to the power supply.

[0065] The dust removal component 8 includes a filter fan 81. When the alarm component 7 is powered on or off, the filter fan 81 is powered on and works. The dust removal component 8 introduces the overflow gas from the die-cutting position into the dust removal component 8 for processing and then discharges it.

[0066] Optionally, the dust removal assembly 8 further includes an air intake structure and a power supply structure;

[0067] The air inlet structure includes a bellows 82 fixed on the hollow platform 41 and connected to the channel cavity. One end of the bellows 82 is connected to a collecting member 83. The lower side of the collecting member 83 is open and is arranged on the discharge side after die cutting.

[0068] The power supply structure includes a conductive rod 85 fixed on the hollow platform 41 and correspondingly contacting the other ends of the two conductive wires 57 located at the ends. A battery 84 is arranged in the hollow platform 41 .

[0069] One electrode of the battery 84 is connected to any conductive rod 85 via a wire, and the other electrode of the battery 84 and the other conductive rod 85 are connected to the positive and negative terminals of the filter fan 81 via a wire. The filter fan 81 is arranged in the channel cavity.

[0070] Among them, when the mother mold 51 is installed with the hollow table 41, the conductive wire 57 is in contact with the conductive rod 85; the battery 84 is used as a DC power supply. In order to maintain safety, the battery 84 is used as a DC power supply lower than 36V, and the battery 84 can be charged by an external power supply. When the battery 84 is connected to one end of the conductive rod 85 through a wire, a control switch can be added to control whether the electrode of the battery 84 is connected; the filter fan 81 has a filtering function. When the filter fan 81 is in the power-on state, the gas escaped from the die cutting position enters the opening of the collector 83, and then passes through the bellows 82 and the channel cavity, and is then filtered and discharged by the filter fan 81.

[0071] In this embodiment, during the die-cutting operation, due to the continuous compression of the knife die 6 and the frequent replacement operation, the wooden structure of the knife die 6 may be bent and deformed; therefore, when the knife die 6 is bent, the conductive sheet 62 is deformed along with the deformation of the knife plate 61. Since the knife die 6 is in a normal working state, the knife plate 61 and the conductive sheet 62 are all on the same plane as the mother mold 51, so the conductive sheet 62 is in contact with the conductive column 55, so that the alarm 74 is in a short-circuited state; at this time, the alarm component 7 will not start working, which proves that the knife die 6 is in a normal working state; and when the knife die 6 is deformed, the conductive sheet 62 on the knife plate 61 is separated from the contact with the conductive column 55, and the alarm component 7 will no longer be short-circuited by the conductive sheet 62, and the alarm 74 is in a working state; therefore, the alarm will be triggered, which proves that the conductive sheet 62 is deformed; and since the alarm 74 is in a series connection mode, the power-on of the alarm 74 does not limit any other alarm 74. Whether it is in working state, one or more alarms 74 can be in working alarm state at the same time; and the filter fan 81 is an electrical appliance that is always connected. At this time, the filter fan 81 will reduce the power according to the increase in the number of power-on batteries 84, but it does not affect the work; and during the die-cutting work, since the die-cutting position will increase or decrease, the gas escaping from the die-cutting position will be sucked in by the dust removal component 8 and discharged after filtering; specifically, the escaped gas enters through the collecting part 83, then passes through the bellows 82 and the channel cavity, and is finally discharged after filtering by the filter fan 81, which can reduce the debris generated by adsorption at the die-cutting discharge point and remaining in the air after die-cutting, reduce adhesion to the conveying material structure, and reduce the conveying impact on the conveying material structure.

[0072] The above description is only a preferred embodiment of the present invention, which is only illustrative and not restrictive of the present invention. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but all of them will fall within the scope of protection of the present invention.
