[0048] Two groups of the connecting arms 500 are respectively provided with mounting portions and arc-shaped portions 5102, the mounting portions are used for mounting the tool bits 600, and the arc-shaped portions 5102 are coaxially designed with the mounting portions.

[0049] The connecting arm 500 includes a first connecting rod 510 and a second connecting rod 520, and the lower tool bar 300 includes an inner tool bar 310 and an outer tool bar 320. The inner tool bar 310 is connected with the first connecting rod 510 to form a corner portion 3101, and the outer tool bar 320 is connected with the second connecting rod 520. The second connecting rod 520 is provided with a bending portion 3201, and the bending portion 3201 is parallel to the corner portion 3101.

[0050] The inner tool bar 310 is connected with the first connecting rod 510 to form the corner portion 3101, and the outer tool bar 320 is connected with the second connecting rod 520. The second connecting rod 520 is provided with the bending portion 3201. Such a structure design allows the inner tool bar 310 and the outer tool bar 320 to work cooperatively or independently. When a cutting instruction is issued, the lower tool bar 300 drives the connecting arm 500 to move. The parallel design of the bending portion 3201 and the corner portion 3101 ensures uniform distribution of force and synchronization of tool movement. This design allows the tool bit assembly to maintain precise control and high stability when performing complex cutting tasks.

[0051] In addition, the parallel design of the corner part 3101 and the bending part 3201 achieves structural compactness, the use of the first connecting rod 510 and the second connecting rod 520, and the design of the inner cutter bar 310 and the outer cutter bar 320 are all to reduce the occupied space of mechanical parts while maintaining mechanical strength and stability. The parallel layout of the bending part 3201 and the corner part 3101 not only helps to evenly distribute forces, but also helps to reduce the transverse size of the connecting arm 500, so that the entire cutter head assembly can be designed more compactly. This compact structural design helps to reduce the overall size of the machine, improve space utilization, and also make the appearance of the machine more neat and beautiful. Through this space-saving and compact structural design, the eccentric cutting sports car can operate efficiently in limited working space, especially suitable for working environments with limited space, such as small workshops.

[0052] The cutter head 600 includes an outer cutter head 610, the mounting part includes a first mounting part 5101 and a second mounting part 5201, the second mounting part 5201 is provided on the second connecting rod 520 for mounting of the inner cutter head 620, and the arc-shaped part 5102 is provided on the first connecting rod 510, and the second mounting part 5201 is coaxially designed with the arc-shaped part 5102;

[0053] The cutter head 600 also includes an inner cutter head 620, the first mounting part 5101 is provided on the first connecting rod 510, and the first mounting part 5101 is used for mounting and fixing the inner cutter head 620;

[0054] The first mounting part 5101 and the second mounting part 5201 are both cylindrical, the arc-shaped part 5102 is wrapped around the second mounting part 5201, that is, the second mounting part 5201 and the arc-shaped part 5102 are coaxially designed, and the spacing between them is designed to be less than 5mm. Such coaxial and extremely small spacing design can ensure the compact cooperation between the cutter heads, and the smaller spacing reduces the overall occupied space of the equipment and improves the mechanical flexibility of the equipment. Through coaxial design and extremely small spacing adjustment, the space requirement is reduced, compared with the traditional cutter head setting in the front end of the equipment, this design significantly reduces the volume of the equipment, so that it can be more flexibly installed in different production environments. In addition, the coaxial design allows the inner cutter head 620 and the outer cutter head 610 to be accurately aligned on the same axis, reducing the possibility of cutter head misalignment. When the cutting tool works on the same axis, the movement is more synchronous and consistent, avoiding the accumulation of errors when the cutter head runs in the traditional different shaft design, thereby improving the cutting accuracy and the stability of the equipment operation.

[0055] Specifically, the outer cutter head 610 and the inner cutter head 620 are respectively controlled by independent electromagnets 400 and elastic members 900. Such a design is mainly to improve the flexibility and precision of the equipment. In traditional cutting equipment, the cutter head can only perform the same operation at the same time, and cannot separate the cutting and indentation operations. In the present embodiment, since the driving systems of the outer cutter head 610 and the inner cutter head 620 are completely independent, the two cutter heads can cut down at the same time, or cut down or lift up according to different process requirements, realizing independent operation. This design makes the equipment have stronger adaptability in different application scenarios and can cope with complex production requirements. In addition, since each cutter head is controlled by an independent electromagnet 400 and elastic member 900, the outer cutter head 610 and the inner cutter head 620 can perform different functions, and the action of each cutter head is independent and controllable. This design not only improves the precision of cutting and indentation, but also avoids the interference problem caused by the synchronous operation of the two cutter heads, ensuring the stability of the cutter head operation. The cutting equipment of the present embodiment is suitable for cutting different patterns and indenting different materials, and is particularly suitable for cutting advertising materials such as adhesive stickers and instant stickers. In these scenarios, multiple cutting and indentation operations are usually required for the materials. Through the design of the double cutter heads, two processes can be completed at the same time, improving production efficiency.

[0056] The connecting arm is provided with a tightening member and a fixed block, and the fixed block is fixedly connected with the connecting arm through the tightening member.

[0057] The fixed block is fixed on the connecting arm through the tightening member, and the cutter head is stably installed through the fixed block and the connecting arm, so as to ensure the stability of the equipment during cutting.

[0058] The driving assembly further comprises an elastic member 900 arranged on the upper end of the cutter rod 300. When the electromagnet 400 is powered on, the elastic member 900 is compressed, so that the cutter rod 300 moves along the first direction. When the electromagnet is powered off, the cutter rod 300 moves along the opposite direction of the first direction under the action of the elastic member 900.

[0059] The elastic member 900 is a spring.

[0060] The elastic member 900 in this embodiment adopts a spring design, and the diameter of the spring ring gradually increases along the direction of the cutter head. The purpose is to adapt to different cutting states and pressure changes of the eccentric cutting runner. By changing the diameter of the spring ring, the distribution of elastic force can be effectively adjusted, ensuring that the spring can provide stable and gradually increasing reaction force at different cutter head positions. This gradually changing design helps to improve the stability and precision during cutting, especially when the electromagnet 400 is powered on and off, which can better cooperate with the action of the elastic member 900, ensuring that the double cutter head can run smoothly during the down-cutting and up-cutting processes.

[0061] When the electromagnet 400 is powered on, the cutter head moves downward along the first direction, and the spring is gradually compressed. Since the diameter of the spring ring gradually increases, the part of the spring near the cutter head can withstand greater compression force and provide stronger reaction force. When the electromagnet 400 is powered off, the compressed part of the spring begins to recover to its original state, gradually releasing its stored elastic potential energy. The gradual change in the diameter of the spring ring makes the elastic force release process more stable, reducing the problem of sudden rebound or excessive recovery, thereby ensuring that the down-cutting rod 300 is more stable during the reset process and does not have the phenomenon of shaking or jamming.

[0062] Another embodiment of the utility model provides a cutting machine, including any one of the above embodiments, the cutting machine is installed on the eccentric cutting runner, and is detachably connected with the eccentric cutting runner.

[0063] By installing the cutting machine on the eccentric cutting runner, the equipment layout is effectively optimized. Eccentric motion allows the equipment to perform more complex cutting operations in a smaller space, thereby reducing the floor area occupied by the equipment, and is particularly suitable for scenarios where the production line space is limited.

[0064] The utility model discloses an eccentric cutting car and cutting machine, through adopting two independent cutter heads, namely outer cutter head 610 and inner cutter head 620, cooperate independent electromagnet 400 and elastic part 900, in the working process, after the electrification of electromagnet 400, through magnetic attraction drive outer cutter bar 320 and inner cutter bar 310 move down, drive outer cutter head 610 and inner cutter head 620 carry out the cutting of down knife action simultaneously, realize. When electromagnet 400 is powered off, the elastic part 900 releases the tension under the condition of being compressed before, pushes down cutter bar 300 back to the original position, realizes the action of lifting knife, and the elastic part 900 provides stable supporting force when compression, ensures the smooth movement of cutter bar in the vertical direction, and the electric control characteristic of electromagnet 400 ensures the accuracy of each down knife and lifting knife action, and the double cutter head design allows to complete cutting simultaneously in one operation, and it is not necessary to handle the file many times, by adopting double cutter head structure, avoid the drawbacks that traditional equipment needs twice operation, improve production efficiency significantly, especially suitable for the scene that needs to handle a large number of labels, adhesive sticker and other materials.
