It is mainly used to process knitted blank fabrics of various structures. During the production of the circular knitting machine, its central component is a circular cylindrical structure, and cutting operations need to be performed on it.

[0003] In the prior art, the Chinese patent with the publication number CN112276491A discloses an automated flexible manufacturing process for the central group of circular knitting machines. Among them, a positioning and grasping device is used to initially position the loop-forming cam blank; by processing a needle track protrusion for the sliding of knitting needles on the side wall of the loop-forming cam at one time, and then cutting the loop-forming cam with the processed needle track protrusion, the processing efficiency of the cam is improved, and the cams are processed from the same loop-forming cam, making it easier for the cutting surface of the cam and the adjacent cam cutting surface to be fitted and connected together, reducing the fitting error.

[0004] Combined with the above materials, it can be seen that in the prior art, laser cutting is generally used to perform forming operations on the central components of circular knitting machines. However, in actual use, due to the generation of certain waste residues during cutting, if the waste residues are not processed, it will affect subsequent processing operations. Content of the Utility Model

[0005] The purpose of the utility model is to provide an intelligent forming and energy-saving manufacturing unit for the central group of circular knitting machines to solve the problem that cutting waste residues affect subsequent processing operations proposed in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: An intelligent forming and energy-saving manufacturing unit for the central group of circular knitting machines, including a working platform horizontally placed on the ground. In the middle position of the upper surface of the working platform, a placement table is installed, and a main controller is fixedly installed on the left side of the upper surface of the working platform. It also includes:

[0007] Above the placement table, a central group workpiece to be cut and formed is placed. On the left side of the upper surface of the working platform, a multi-axis rotating robotic arm is installed, and a laser cutter for cutting the central group workpiece is installed at the top of the robotic arm. At the edge position of the upper surface of the placement table, a cleaning mechanism for cleaning cutting residues is provided;

[0008] Above the placement table, a clamping block for clamping the central group workpiece is installed, and the clamping block forms a sliding structure with an electric sliding rod fixedly installed inside the placement table.

[0009] Preferably, the cleaning mechanism includes a cleaning nozzle fixedly installed at the edge of the upper surface of the placement table, and an air bag is fixedly installed outside the side surface of the placement table.

[0010] Preferably, the air bag and the cleaning nozzle form a communicating structure through a connecting hose fixedly installed therebetween, and the cleaning nozzles are evenly distributed at equal intervals and the outlets face inwards.

[0011] Preferably, the air bag and a pressing plate fixedly installed on the side surface of the robotic arm are at the same height and press against each other, and the pressing plate is arranged in an arc-shaped structure.

[0012] Preferably, a driven gear is fixedly installed on the side surface of the placement table, and the driven gear is meshed with a driving gear rotatably installed above the placement table, and the driving gear is driven by a motor inside the placement table.

[0013] Preferably, a collection bin is opened inside the working platform, and the collection bin communicates with a dust falling groove opened at the center position of the placement table.

[0014] Preferably, a conveyor belt is rotatably installed inside the collection bin, and an electromagnet for adsorbing metal waste is fixedly installed on the upper wall inside the collection bin.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The intelligent forming energy-saving manufacturing unit for the circular knitting machine central group adopts a new structural design, and the specific content is as follows:

[0016] 1. The clamping block slides on the electric sliding rod to clamp and fix the central group workpiece, and then the robotic arm and the laser cutter are started to perform cutting operations on the central group workpiece, and finally the forming is completed. During the cutting process, the rotation of the placement table is driven by the meshing between the driving gear and the driven gear, so as to complete continuous cutting, reduce the pause of the device, and achieve the purpose of energy conservation and environmental protection;

[0017] Furthermore, during the rotation of the placement table, the air bag fixedly installed on its outer surface moves synchronously. When the air bag moves to the position of the pressing plate, the air bag is pressed by the pressing plate, so that the air in the air bag is ejected from the cleaning nozzle through the connecting hose, and the air flow ejected from the cleaning nozzle can cool the cutting position.

[0018] 2. The air flow ejected from the cleaning nozzle can also blow the waste residue generated during cutting into the dust falling groove in the middle. Then, the waste residue falls into the surface of the conveyor belt in the collection bin through the dust falling groove, and the conveyor belt is used to convey the waste residue to the outside, which is convenient for the staff to collect it;

[0019] Furthermore, an electromagnet is fixedly installed on the upper inner wall of the collection bin. The magnetic property of the electromagnet can be used to adsorb and recycle the metal materials in the waste residue. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] When using the device, first place the central group workpiece 6 to be cut and formed above the placing table 2, and then turn on the electric slide rod 13 to make the clamping block 12 slide outside the electric slide rod 13, and finally realize the clamping and fixing operation of the central group workpiece 6. After the fixing is completed, turn on the robotic arm 4 and the laser cutter 5, and use the laser cutter 5 to cut the central group workpiece 6. While cutting, the motor inside the working platform 1 drives the driving gear 15 to rotate, and the meshing between the driving gear 15 and the driven gear 14 drives the placing table 2 to rotate, realizing the continuity of cutting.

[0030] Embodiment Two: Please refer to Figures 2 - 4 , in order to solve the problem that the cutting waste residue of the traditional device is inconvenient to clean during use in this embodiment, the following technical solutions are provided, and the waste residue falling during cutting is cleaned by the air flow ejected by the cleaning structure.
