TECHNICAL FIELD

[0001] The present application relates to the technical field of uniform feeding equipment of green anode paste, in particular to a carbon paste uniform feeding device. BACKGROUND

[0002] The paste vibration feeder is a device for uniformly feeding paste in the anode production process. The second-stage forming paste vibration feeder uses a vibration motor as a vibration source, and adjusts the angle of the feeder trough through a crank arm by extending or retracting the oil cylinder. When feeding normally, the vibration motor operates at a power frequency, and the feeder is in the middle position; when feeding stops, the vibration motor operates at a low frequency, and the oil cylinder retracts, and the trough is turned to the high position; if emergency discharge occurs, the vibration motor operates at a power frequency, and personnel turn the trough to the low position through the on-site control cabinet. The feeder trough frequently lifts or lowers, and there is a large impact during the action process. In addition, the feeder is heavy, and the crank arm or connecting shaft is prone to breakage. Production personnel need to check the paste condition at the feeder at irregular times and make corresponding production adjustments. If the crank arm or connecting shaft breaks down at this time, personnel injury or more serious accidents may occur, and the downstream equipment may also be damaged. On the other hand, after the metering scale completes feeding, the trough needs to be turned up. During the turning process, part of the material will fall into the feeder, and the metering accuracy and stability of the metering scale are poor. Generally, the actual discharge amount of the metering scale can deviate by 10 kg. Furthermore, in order to achieve uniform distribution of the paste, a material distribution device is installed at the lower part of the outlet of the trough. Production personnel need to adjust the material distribution device according to the height of the green anode product. Due to the "slope effect", large particle accumulation occurs on one side of the material distribution device, and the upper surface of the green anode product is seriously rough. SUMMARY

[0003] The purpose of the present application is to provide a carbon paste uniform feeding device, which solves the problems of reducing the action amplitude of the trough of the conventional carbon paste uniform feeding device and reducing the action frequency of the trough of the feeder.

[0004] To solve the above technical problems, the present application adopts the following technical scheme:

[0005] This invention provides a carbon paste uniform feeding device, comprising a feeder trough mounted on a frame and driven to vibrate by a vibration motor, trough mounting beams respectively mounted on both sides of the feeder trough, and a trough tilting cylinder mounted on the frame via a hinged seat; wherein the two ends of the trough mounting beams are respectively hinged to the side walls of the feeder trough via trough shock absorbers; a connecting shaft is provided on the middle side wall of the trough mounting beam, and the connecting shaft is mounted on the frame via a bearing seat; the telescopic end of the trough tilting cylinder is connected to the connecting shaft via a crank arm, and the trough tilting cylinder drives the trough mounting beams to deflect, thereby causing the feeder trough to tilt;

[0006] The feed trough of the feeder is equipped with a pneumatic baffle device to control the opening and closing of its feed port;

[0007] The pneumatic baffle device includes bearing seats on both sides of the feed inlet of the feeder trough, a baffle plate mounted on the bearing seats via a rotating shaft, and a cylinder connected to the rotating shaft via a connecting arm and driving it to deflect.

[0008] A material distribution device is provided inside the material trough of the material feeder and near its discharge port.

[0009] Furthermore, the vibration motor drives the feeder trough to vibrate via an eccentric wheel or crank transmission mechanism.

[0010] Furthermore, the feeder trough has a scoop-shaped structure.

[0011] Furthermore, the cylinder is disposed on the side wall of the feeder trough.

[0012] Furthermore, the material distribution device includes two parallel lead screws, an adjusting plate mounted on one of the lead screws via a lead screw nut pair, and a material distribution plate vertically hinged to the bottom of the adjusting plate.

[0013] The lead screw includes a first lead screw and a second lead screw, which are respectively mounted on the feeder trough via supports;

[0014] Or / and, the two ends of the first lead screw and the second lead screw are respectively mounted on the support by bearings, and a crank is provided at one end of the lead screw extending out of the support;

[0015] A deflection adjustment component is provided on the second lead screw via a lead screw nut pair. An elongated hole is provided in the deflection adjustment component. An arc-shaped limiting groove corresponding to the elongated hole is provided on the adjustment plate. A sliding shaft passing through the arc-shaped limiting groove and the elongated hole is provided on the material distribution plate.

[0016] Furthermore, the material distribution device includes a material distribution plate hinged to the feeder trough and a telescopic cylinder hinged to the outside of the feeder trough for adjusting the deflection of the material distribution plate.

[0017] Or / and, the telescopic cylinder is an electric telescopic cylinder, and its telescopic end is hinged to the material distribution plate through a deflection arm.

[0018] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0019] In this application, the feeder trough does not rotate during normal production, eliminating the risk of breakage of the crank arm and connecting shaft. This ensures production continuity while guaranteeing the personal safety of personnel working in this area, thus improving the inherent safety of the equipment. Simultaneously, a pneumatic baffle is used to open and close the feeder trough's discharge port, preventing overfeeding and improving the accuracy and stability of the weighing scale. A material distribution device is installed inside the feeder trough, eliminating the "slope effect" of material during discharge and significantly improving the appearance qualification rate of green anode products. Production personnel do not need to work under the feeder when adjusting the material distribution, reducing the risk of injury to personnel to a certain extent. Attached Figure Description

[0032] In specific implementation, the two ends of the first lead screw 73 and the second lead screw 74 are respectively mounted on the support 71 through bearings, and a crank 72 is installed at one end of the first lead screw 73 and the second lead screw 74 extending out of the support 71. In use, the rotation adjustment of the first lead screw 73 and the second lead screw 74 is achieved by cranking the crank 72.

[0033] A deflection adjustment component 79 is installed on the second lead screw 74 via a lead screw nut pair. An elongated hole is provided in the deflection adjustment component 79. An arc-shaped limiting groove 77 corresponding to the elongated hole is provided in the adjustment plate 76.

[0037] In specific implementation, the telescopic cylinder 7a is an electric telescopic cylinder, and the telescopic end is hingedly connected to the material distribution plate 75 through a deflection arm 7b.

[0038] In this embodiment, specifically:

[0039] The chute installation beam 1: the feeder chute 8 is installed on the chute installation beam 1, and a damping device is installed at the lower part to prevent resonance of the equipment during vibration; at the same time, it is connected with the overturning action driving device to play the role of power transmission during overturning.
