In another embodiment, the asynchronous tool apron 200 includes two sets of cutter bodies 201, and a material pulling shaft 202 and a transmission shaft 203 rotatably disposed between the two sets of cutter bodies 201, that is, the rotatable mounting purpose of the material pulling shaft 202 and the transmission shaft 203 can be achieved by disposing the two sets of cutter bodies 201 opposite to the one set of cutter bodies 201, and in this embodiment, the central axes of the material pulling shaft 202 and the transmission shaft 203 are parallel to each other, so that the die cutting operation of pulling films and single-sided adhesives can be adapted.

The adjusting mechanism 204 may be a conventional bolt adjusting assembly, a telescopic cylinder adjusting assembly, or another linear driving structure, and the first bolt adjusting assembly is adopted herein, which can have the advantages of controllable operation and low cost, specifically, a chute is formed on the cutter body 201, the direction of the chute passes through a connecting line between the pull shaft 202 and the end of the transmission shaft 203, a sliding block is disposed in the chute, an adjusting bolt rotatably connected with the sliding block is screwed on the cutter body 201, the end of the pull shaft 202 is rotatably connected with the sliding block, and the purpose of adjusting the position of the sliding block in the chute is achieved by screwing the adjusting bolt, and finally the purpose of adjusting the gap between the pull shaft 202 and the transmission shaft 203 is achieved. Of course, after the adjusting bolt is screwed in place towards a certain screwing direction, the sliding block is in a state of being blocked in the sliding groove, so that the gap between the sliding block and the transmission shaft 203 is minimum, and the high-precision operation of drawing die cutting can be ensured.

In order to enable the asynchronous cutter holder 200 to be connected with any one of the cutter holders 400 on the circular cutter machine 100, the cutter body 201 is provided with a connecting piece 300 which can be used for being connected with any one of the cutter holders 400 on the circular cutter machine 100, namely, the cutter body 201 is connected with the cutter holder 400 at the corresponding position of the circular cutter machine 100 through a middle piece (the connecting piece 300 here), instead of adopting a direct connection mode, when the asynchronous cutter holder 200 is in a single-side supporting mode, the cutter body 201 is connected with the single-side seat plate of the corresponding cutter holder 400 of the circular cutter machine 100 through the connecting piece 300, and when the asynchronous cutter holder 200 is in a two-side supporting mode, the two cutter bodies 201 are respectively connected with the two side seat plates of the corresponding cutter holder 400 of the circular cutter machine 100 through the connecting piece 300, so that the aim of connecting the asynchronous cutter holder 200 with any one of the cutter holders 400 can be achieved, the cutter body is not limited by the connecting position, the cutter body can be independently powered on for use, the cutter body can also be matched with the corresponding cutter holder 400 for use, and the cutter holder can be well used for die cutting operation aiming at some special products, and the station is quite flexible.

Taking the connection of the cutter body 201 and the single-side seat boards of the corresponding cutter holders 400 of the circular cutter machine 100 through the connecting piece 300 as an example for development (the same reason is adopted for the seat boards on two sides), the connecting groove 205 is processed on at least one side wall of the cutter body 201, namely, the connecting groove 205 can be formed on one side wall or multiple side walls of the cutter body 201, the cutter holders 400 in different directions or positions can be simultaneously connected through the connecting piece 300, and the connecting groove 205 for the side wall of the cutter body 201 in the required direction can also be connected with the cutter holders 400 through the connecting piece 300, so that the use is relatively flexible. For the form of the connecting groove 205, it may be a blind groove or a through groove, and here, the through groove is adopted, that is, the connecting groove 205 penetrates through two ends of the side wall of the cutter body 400 where the connecting groove is located, and can be mutually matched with the side wall groove (through groove) of the cutter holder 400, so that the connecting piece 300 is convenient to install, that is, the connecting groove 205 can be detachably connected with the side wall groove of the corresponding side wall of the cutter holder 400 on the circular cutter 100 through the connecting piece 300. The sidewall groove of the tool holder 400 of the conventional circular tool machine 100 is usually in a through groove form, and the groove direction and the through form of the connecting groove 205 are mutually matched with the sidewall groove, so that the connecting piece 300 can be accommodated for being matched and smoothly installed, thereby achieving the purpose of detachably connecting the tool body 201 with the corresponding tool holder 400.

In addition, the side wall of the tool post 400 of the circular cutter 100 is generally provided with a plurality of side wall grooves which are uniformly arranged up and down, and in order to adapt to the form, the side wall of the tool body 201 is provided with a plurality of connecting grooves 205 which are uniformly arranged up and down, and the vertical arrangement mainly means that the connecting grooves are arranged along one end to the other end of the tool body 201. Each connecting groove 205 has a trend consistent with the axial direction of the material pulling shaft 202 or the transmission shaft 203, so as to be identical or similar to the groove shape of a plurality of side walls of the tool apron 400, and achieve higher connection suitability. Each of the connecting grooves 205 on the side wall of the cutter body 201 can form a connecting space with any side wall groove on the side wall of the corresponding cutter holder 400, that is, any connecting groove 205 can be mutually spliced with any side wall groove to form the connecting space, and of course, a plurality of connecting grooves 205 and a plurality of side wall grooves can be combined together to form a plurality of connecting spaces, and the plurality of connecting spaces form the above-mentioned up-down arrangement. The connecting piece 300 is detachably disposed in a single connecting space and enables the cutter body 201 and the corresponding cutter holder 400 to be connected with each other, and when the number of the connecting spaces is plural, each connecting space is configured with the connecting piece 300, thereby achieving higher connection stability between the cutter body 201 and the corresponding cutter holder 400.

The detachable connection manner between the connecting piece 300 and the connecting groove 205 and the side wall groove can be a buckling connection, a screw connection, a clamping connection or a magnetic connection, and the like, and the magnetic connection manner is adopted here, so that the detachable connection state can be adapted to the cutter body 201 and the cutter holder 400 made of metal materials and is stable and convenient to detach. Specifically, the connecting space is a cylindrical space, a cylindrical space or a prismatic space, where the former is the former, the connecting piece 300 includes a cylindrical connecting column 301 and adjustable clamping assemblies 302 disposed at two ends of the connecting column 301, and the middle part of the connecting column 301 can be embedded into the connecting space and can fill the connecting space, so that the two groups of adjustable clamping assemblies 302 are respectively located at two sides of the cylindrical space and respectively clamp two sides of the tool body 201 and two sides of the corresponding tool apron 400. The clamping assembly 302 may be fixed on the connecting post 301, or may be mounted on the connecting post 301 with an adjustable position, so long as the purpose of being able to contact the side wall of the cutter body 201 and the corresponding cutter holder 400 is satisfied. The surface of the adjustable clamping assembly 302, which contacts the cutter body 201 and the corresponding cutter holder 400, is provided with a suction magnet 303, so that the cutter body 201 and the corresponding cutter holder 400 are connected together through the suction magnet 303, and the detachable connection between the cutter body 201 and the corresponding cutter holder 400 is realized in a magnetic connection mode. The adsorption magnet 303 and the permanent magnet, one side main surface of which is fixed on the adjustable clamping component 302 through bolts, and the other side main surface of which is used for simultaneously adsorbing the side wall of the cutter body 201 and the corresponding cutter holder 400, through the design, the preliminary accurate splicing of the cutter body 201 and the corresponding cutter holder 400 can be achieved under the preliminary positioning action of the connecting column 301, and the purpose of fixing the cutter body 201 and the corresponding cutter holder 400 is achieved through the adsorption magnet 303.

In order to improve the convenience and operability of the adjustable clamping assembly 302 and the adsorption magnet 303, the phenomenon of contact obstacle between the cutter body 201 and the corresponding cutter holder 400 is avoided as much as possible, for example, the contact is possible due to too small clamping gap or the distance is too close to be adjustable, so that the magnetic attraction force is too large and inconvenient to move. The adjustable clamping assembly 302 in this embodiment is in a form that the adjustable clamping assembly 302 can be installed on the connecting column 301 in a position adjustable manner, the adjustable clamping assembly 302 is installed on the connecting column 301, the relative movement mode can be a mode of mutual threaded connection, sliding connection or telescopic connection, the purpose of continuous adjustment can be achieved by adopting the mode of mutual threaded connection, and the connection stability is relatively high. Specifically, the connecting column 301 includes a reducing section 3011 and an expanding section 3012 coaxially formed at two ends of the reducing section 3011, and two groups of adjustable clamping assemblies 302 are respectively connected to the expanding sections 3012 at two ends, so that when the adjustable clamping assemblies 302 approach from the expanding section 3012 to one side of the reducing section 3011, an oversized obstacle of the reducing section 3011 cannot exist, the reducing section 3011 is embedded into the connecting space, and the expanding sections 3012 at two ends limit the connecting space to prevent the reducing section 3011 from separating from the connecting space, thereby achieving the purpose of enhancing the positioning function.

Taking the connection of the single adjustable clamping assembly 302 and the single expanding section 3012 as an example, the expanding section 3012 is provided with threads, the adjustable clamping assembly 302 comprises an outer threaded sleeve 3021, the outer threaded sleeve 3021 and the expanding section 3012 are mutually in threaded connection, namely, the outer threaded sleeve 3021 is in threaded connection and sleeved on the expanding section 3012, and the end face of the outer threaded sleeve 3021, close to the reducing section 3011, is fixed with the adsorption magnet 303. The initial position of the outer screw sleeve 3021 is located at the portion of the expanded diameter section 3012 away from the reduced diameter section 3011, so that the problem that the adsorption magnet 303 collides with or is too close to the adsorption surface when the reduced diameter section 3011 and the connecting space are clamped and embedded with each other can be avoided, the outer screw sleeve 3021 is rotated and made to move towards one side of the reduced diameter section 3011, and finally the adsorption magnet 303 and the surface of the cutter body 201 are in mutual adsorption contact with the surface of the corresponding cutter holder 400, so that convenience in clamping operation of the cutter body 201 and the corresponding cutter holder 400 can be effectively improved. In this embodiment, the adsorbing magnet 303 is annular, the adsorbing magnet 303 is sleeved on the connecting post 301, and a certain gap is formed between the inner hole of the adsorbing magnet 303 and the outer annular wall of the connecting post 301, that is, the adsorbing magnet 303 can be sleeved on the diameter-reduced section 3011 or the diameter-expanded section 3012, and in a non-contact sleeved mode, the interaction between the adsorbing magnet 303 and the connecting post 301 can be reduced, so that the adsorbing magnet can be magnetically attracted with the cutter body 201 and the corresponding cutter holder 400 smoothly.

Considering that the manner of screwing the outer screw sleeve 3021 to achieve the contact of the suction magnet 303 and the suction of the cutter body 201 and the surface of the corresponding cutter holder 400 may increase the operation convenience, especially the closer the suction magnet 303 is to the surface of the cutter body 201 and the surface of the corresponding cutter holder 400, the screwing difficulty of the outer screw sleeve 3021 may increase, and the adjustable clamping assembly 302 in this embodiment adopts a two-stage pushing feeding manner, specifically, the adjustable clamping assembly 302 further includes an inner screw sleeve 3022, and the inner hole wall of the outer screw sleeve 3021 includes a diameter-reducing hole section and a diameter-expanding hole section which are coaxially distributed, that is, the inner hole of the outer screw sleeve 3021 is a two-stage stepped hole. The diameter-reducing hole section and the diameter-expanding section 3012 are in threaded connection with each other, an annular embedded cavity is formed between the diameter-expanding hole section and the diameter-expanding section 3012, the inner screw sleeve 3022 can be inserted into the embedded cavity, the outer wall of the inner screw sleeve 3022 and the inner hole wall of the outer screw sleeve 3021 are in threaded connection with each other, that is, the inner screw sleeve 3022 can be wholly or partially inserted into the embedded cavity, the inner screw sleeve 3022 is inserted into the embedded cavity, the smooth surface is not in movable insertion, and the threaded connection is inserted, however, by the corresponding design of the threads of the diameter-expanding section 3012, the inner threads of the inner screw sleeve 3022, the outer threads of the outer screw sleeve 3021 and the inner screw sleeve 3022, the threads of the outer screw sleeve 3021 can be synchronously moved on the diameter-expanding section 3012, and the inner screw sleeve 3022 can be freely rotated to withdraw from the embedded cavity or continuously enter the embedded cavity when the outer screw sleeve 3021 and the diameter-expanding section 3012 are relatively fixed.

That is, when the outer screw sleeve 3021 is rotated, the inner screw sleeve 3022 moves along, when the diameter-reducing section 3011 of the diameter-reducing hole Duan Kaojin is separated from the diameter-enlarging section 3012, the inner screw sleeve 3022 can be continuously screwed into the embedded cavity and pushes the outer screw sleeve 3021 to move towards one side of the diameter-reducing section 3011, wherein a fastener which can be movably connected with the inner screw sleeve 3022 is arranged on the outer screw sleeve 3021, so that when the outer screw sleeve 3021 is rotated, the inner screw sleeve 3022 can be synchronously moved, the fastener is in a separation state, and the inner screw sleeve 3022 can be independently screwed into the embedded cavity and pushes the outer screw sleeve 3021. Through the design, the second-stage pushing function of the adjustable clamping assembly 302 can be achieved, the first-stage pushing is that the outer screw sleeve 3021 is connected with the inner screw sleeve 3022 through the fastener, the outer screw sleeve 3021 is screwed, the outer screw sleeve 3021 and the inner screw sleeve 3022 are synchronously and spirally moved in the expanding section 3012, when the adsorption magnet 303 approaches the cutter body 201 and the corresponding cutter holder 400, or the reducing section 3011 is separated from the expanding section 3012, the fastener is in a separated state, the inner screw sleeve 3022 is screwed further, at the moment, two conditions exist, the adsorption force of the adsorption magnet 303 is smaller than the wire friction force between the outer screw sleeve 3021 and the inner screw sleeve 3022, the outer screw sleeve 3021 can move in a follow-up mode, when the adsorption force of the adsorption magnet 303 is larger than the wire friction force between the outer screw sleeve 3021 and the inner screw sleeve 3022, the outer screw sleeve 3021 can linearly move and gradually contact and tightly contact the surface of the cutter body 201 and the corresponding cutter holder 400, the second-stage pushing mode can not only excessively adsorb the cutter body 201 to be in a close state, the adsorption force of the cutter body is required to the rotating section 372, and the operation length of the cutter holder is increased, and the operation is convenient and the cutter body is required to be more convenient to overcome (the conditions that the size of the cutter body is required to be reduced by the rotating and the reducing the size of the cutter body to be compared with the diameter of the cutter holder 201).
