The utility model discloses a kind of multi-nozzle composite extrusion devices with nozzle spacing fine adjustment, it is related to extrusion device technical field, including extrusion assembly and first structural member, the output end side of extrusion assembly is horizontally provided with first structural member, and the side of first structural member close to extrusion assembly is horizontally provided with second adjusting structural member, and the both ends of second adjusting structural member and first structural member are provided with moving member.The multi-nozzle composite extrusion device with nozzle spacing fine adjustment is provided with first structural member, second adjusting structural member, moving member, the combination of the structure of three is used, so that the material extrusion head in the four groups of discharge components connected with it, under the screwing adjustment of bidirectional screw rod, the horizontal vertical spacing between different material extrusion heads is realized micro-adjustment, so as to guarantee the structural flexibility of device, in addition, the structure combination between discharge component and extrusion assembly makes it convenient for operating personnel to split maintenance, provides convenience for operation.

This utility model discloses a small, long-arm, stable clamping mechanism, relating to the field of material clamping. It includes a lower push rod, an upper push rod, a fixing component, a gear, and a cylinder. The fixing component has an upper and a lower sliding track arranged parallel to each other. A cylinder mounting plate is connected to the fixing component. The piston rod of the cylinder is connected to one end of the upper push rod, causing the upper push rod to slide along the upper sliding track. The other end of the upper push rod extends out of the upper sliding track and is fitted with a front gripper. The upper push rod has an upper toothed groove located away from the front gripper, and the lower push rod has a lower toothed groove at a corresponding position. The gear is rotatably connected to the fixing component via a gear shaft, with the upper and lower toothed grooves meshing on the upper and lower sides of the gear, respectively. This allows the upper push rod to slide in the opposite direction along the lower sliding track when it slides. A rear gripper is installed at the end of the lower push rod away from the lower toothed groove. This utility model utilizes the principle of opposite motion after the gear and double rack mesh, and the guide groove of the rack provides sufficient rigidity and depth.
