The application discloses an execution mechanism for bundling and stacking materials and a bundling device. The execution mechanism comprises a head device and a relay device. The head device is used for feeding a belt around a first belt passing channel at a first corner. The relay device is used for receiving and fixing a bundling belt in the first belt passing channel and feeding the belt after receiving and fixing the end of the bundling belt in the first belt passing channel. The relay device is used for feeding the received bundling belt into a second belt passing channel around a second corner at a second corner. The head device is used for receiving the bundling belt in the second belt passing channel and tightening, welding and cutting the received bundling belt around the first corner and the second corner. The execution mechanism realizes automatic bundling of the stacking materials in multidimensional directions, has high working efficiency, saves manpower, reduces the bundling cost, and guarantees the bundling quality and the bundling effect.

The present application belongs to the technical field of zinc material manufacturing, and particularly relates to an automatic metering device for online production of zinc wire, which comprises a workbench, a metering guide wheel and an encoder arranged on the workbench, the encoder and the metering guide wheel are coaxially arranged, and a synchronous mechanism is further arranged on the workbench, the synchronous mechanism comprises a clamping belt body and a guide wheel set, the clamping belt body is attached to the metering guide wheel by means of the guide wheel set and drives the metering guide wheel to rotate synchronously, the opening and closing side of the clamping belt body faces the metering guide wheel and has the freedom of opening and closing, the opening and closing side of the clamping belt body is used for allowing the zinc wire to enter the clamping channel of the clamping belt body, and the zinc wire is synchronously rotated with the clamping belt body by means of the clamping and wrapping of the clamping belt body. The synchronous mechanism is additionally arranged, the zinc wire is clamped and wrapped by the clamping belt body with a high friction coefficient, the zinc wire moves synchronously with the clamping belt body, the metering guide wheel and the zinc wire have the same movement amount by indirectly driving the metering guide wheel by the clamping belt body, and the accurate length of the zinc wire is accurately collected by the encoder.

The application discloses a planting disc conveying trolley and a planting disc conveying system, and belongs to the technical field of conveying equipment. The planting disc conveying trolley comprises a trolley body, the trolley body comprises a base, a first side plate, a second side plate and a third side plate, wherein the first side plate, the second side plate and the third side plate are perpendicularly fixed on the base and surround to form a bearing space capable of accommodating at least one planting disc; at least two supporting parts are arranged on the base along the length direction of the trolley body, and are used for supporting the planting disc, so that a gap is formed between the bottom of the planting disc and the base; the middle part of the third side plate is opened, so that the side of the base towards the opening protrudes and extends to form an integrated connecting part, at least one slot-shaped hollow opening is formed in the vertical direction of the base, and the connecting hole at the bottom of the slot-shaped hollow opening can be connected with a driving assembly.

This invention discloses a welding fixture with back gas protection, belonging to the field of welding technology. It includes a worktable and two workpieces to be welded. The worktable has a welding port located at the bottom of the workpiece to be welded. A reduction gearbox is mounted on one side of the worktable. The input end of the reduction gearbox is connected to a motor, and the output end is connected to a lower lead screw and an upper lead screw. The workpieces to be welded are located between the lower and upper lead screws. A protective cover is connected to the lower lead screw, and a welding torch and a drive block are connected to the upper lead screw. The welding port of the welding torch is located between the two workpieces to be welded and directly above the protective cover. This welding fixture with back gas protection solves the technical problems of existing devices, such as difficulty in achieving synchronous movement between the back gas output device and the welding head, lack of versatility, and limited ability to control the flow direction of the protective gas.

The utility model relates to an auxiliary supporting structure, in particular to an auxiliary supporting structure for a mold. The auxiliary supporting structure for the mold comprises a base, a frame body, a supporting table, sliding blocks, a sliding frame, a clamping block, a second screw rod, a positioning plate, a third screw rod and a driving assembly, the frame body is placed at the top of the base, the supporting table is connected to the top of the frame body, and the sliding blocks are connected to the left side, the right side, the front side and the rear side of the supporting table in a sliding mode respectively.
