The invention discloses a silk-screen printing device capable of reducing silver paste consumption. The silk-screen printing device comprises a rack; a vibration assembly and a printing table; a leveling assembly; the silk screen assembly comprises a silk screen plate, the printing assembly comprises a translation assembly and a paste scraping assembly, the paste scraping assembly comprises a paste scraping unit, the paste scraping unit comprises a roller and a roller sleeve, and the translation assembly drives the paste scraping assembly to reciprocate in the length direction of the silk screen plate; the movable assembly comprises a lifting unit and an elastic connecting unit; and a butt joint assembly. According to the silk-screen printing device capable of reducing silver paste consumption, the elastic roller sleeve is supported through the rigid roller, silver paste is extruded to penetrate through meshes in the silk-screen plate through the roller sleeve rotating around the axis of the roller sleeve, abrasion of the silk-screen plate is reduced, it is guaranteed that the silver paste is attached to a battery piece after being pressed, the printing quality is improved, and the printing efficiency is improved. The roller sleeve extrudes slurry attached to the surface of the roller sleeve through rotation, the residual amount is reduced, and therefore silver slurry on the silk screen plate can be fully used, and the use amount of the silver slurry is reduced.

The utility model belongs to the field of unloading machine, belongs to vertical spiral unloading machine, the utility model discloses a rack, vertical material conveying mechanism and horizontal material conveying mechanism, vertical material conveying mechanism is installed on the rack vertically, horizontal material conveying mechanism is installed on the rack horizontally, vertical material conveying mechanism top with horizontal material conveying mechanism intercommunication, and material is transported from vertical material conveying mechanism to horizontal material conveying mechanism, and then is unloaded by horizontal material conveying mechanism again, vertical material conveying mechanism includes vertical spiral machine, feeder and scraper, vertical spiral machine bottom feed inlet is installed with feeder, and the both sides of feeder are provided with scraper, and vertical spiral machine top outlet communicates with the feed inlet of horizontal material conveying mechanism. Solve the problem of keeping high productivity, and have flexibility and reliability simultaneously, be applicable to the bulk material unloading operation problem of a variety of complex working conditions, abandon the redundancy material collector and double spiral configuration, through the synergistic effect of single vertical spiral mechanism and adjustable scraper, simplify the equipment structure, reduce the manufacturing cost and maintenance difficulty.

The invention relates to the technical field of epoxy resin injection molding, in particular to a double-cylinder multi-station power-assisted forming mold which comprises a mold, a back plate and an automatic demolding assembly, the automatic demolding assembly comprises a first driving system, a second driving system, an inserting rod, a mold head and an inserting plate, and the inserting plate is located below the inserting rod and connected with the driving end of the first driving system; the front surface of the plugboard is contacted with the die head; a locking groove is formed in the inserting rod, the die head penetrates through the locking groove to abut against the front face of the inserting plate, the front face of the inserting plate is of an inclined face structure, and the die head is located at the bottom of the inclined face of the inserting plate during locking. Locking and demolding of the mold are achieved through the automatic demolding assembly, the inserting plate is designed to be the inclined face and achieves automatic demolding together with the fixed mold back plate and the mold head, the first driving system drives the inserting plate to move downwards, the mold head is ejected out of the back plate under the action of the inclined face, and therefore automatic demolding is achieved. Meanwhile, a second driving system is designed to insert and retreat from an insertion rod, and the mold head and the back plate are connected through the insertion rod.

The utility model discloses a valve body forging and pressing forming die for a fracturing pump, relates to the technical field of fracturing pump machining dies, and aims to solve the problems that when an existing valve body is forged and pressed, the tonnage of a forging press is large, excessive materials exist, and waste is caused. Comprising a mounting seat, an upper die seat and a lower die seat, the mounting base is connected with a lower die base through a fixing piece, and a lower die core is further arranged in the lower die base; the first upper die base and the second upper die base are connected on the steering mechanism in a sliding mode, a spring is further arranged between the first upper die base and the steering mechanism, the two sets of upper die bases are arranged, the upper die cores of different structures are arranged in the two sets of upper die bases, and the two sets of upper die bases are matched with the lower stamping grooves in the lower die cores, so that two-time stamping forming of the valve body can be achieved; the support legs at the bottom of the valve body are subjected to punch forming firstly, then the top of the valve body is subjected to punch forming, the forming quality is guaranteed, the situation that the support legs of the valve body are not completely punched is avoided, and forging forming of the valve body can be completed through a kiloton forging press.

The utility model discloses foam forming equipment. The foam forming equipment comprises a mounting seat, a forming barrel, a fixing frame, a barrel cover, a connecting plate and a floating plate, the forming barrel is placed in the mounting seat; the fixing frame is fixedly connected to the top end of the mounting base, a first lifting cylinder and a second lifting cylinder are mounted in the fixing frame, the first lifting cylinder is downwards connected with a first output shaft towards the forming barrel, and the second lifting cylinder is downwards connected with a second output shaft; the barrel cover is connected to the tail end of the first output shaft; the connecting plate is connected to the tail end of the second output shaft, and the second output shaft penetrates through the barrel cover, so that the connecting plate is arranged below the barrel cover in parallel; the floating plate is connected below the connecting plate in a lifting mode through a connecting rod penetrating through the connecting plate, the connecting rod is sleeved with a spring, and the spring is clamped between the floating plate and the connecting plate, so that the floating plate can float at the top end of a material in the forming barrel and tightly press the material under the elastic action of the spring, and the top end can be kept flat after the material is formed. Excess materials cut by foam cutting equipment subsequently are reduced, and the cost is saved.
