Description

Technical Field

[0001] The invention relates to the technical field of battery plate production, and in particular to a flow-assisting vibrator for a battery plate mixing barrel. Background Art

[0002] The manufacture of electromagnetic plates involves the mixing of multiple materials, such as metal powder, insulating materials, adhesives, etc., so the mixing barrel plays an important role in the production of electromagnetic plates. The mixing barrel makes the materials in the barrel move relative to each other through the rotation or vibration of the stirring mechanism, thereby achieving mixing. The design of the stirring mechanism will directly affect the mixing effect, including the shape, number, arrangement and stirring speed of the stirring blades. In the production of electromagnetic plates, the mixing barrel needs to ensure that various raw materials can be evenly mixed to achieve the required physical and chemical properties.

[0003] In the prior art, the battery plate needs to vibrate the mixing barrel with the help of an external vibrator during the production process, and most vibrators use vibration motors to vibrate it directly. There are many production steps that utilize gas circulation in the production process of battery plates. For example, in the battery assembly process, it is necessary to ensure that the sealing between the bipolar plates, gas diffusion layers, catalyst layers and other components is good to prevent leakage of reaction gases. This usually involves the selection of sealing materials and the application of sealing processes. Although this step itself does not directly involve the circulation of gas; or there is usually a gas diffusion layer between the bipolar plate and the catalyst layer. The main function of this layer is to provide a path for the reaction gas from the flow field channel to the catalyst layer, ensuring that the gas can smoothly reach the catalyst layer and participate in the electrochemical reaction.

[0004] The flowing gas in the battery production process can be further used in the vibrator for vibration transmission, thereby improving production efficiency and reducing development costs. The existing technology of vibrators has room for further improvement in efficiency Summary of the invention

The bottom end of the transmission plate 44 is fixedly connected with a vibration spring 45, and the end of the vibration spring 45 away from the transmission plate 44 is fixedly connected with a vibration plate 46.

[0036] When using this kind of vibrator for auxiliary flow of battery plate mixing barrel, the vibrator is installed on the surface of the mixing barrel body 1 by fixing bolts. Then, the vibration shell 31 is started to open the solenoid valve 5 on the air inlet channel 312, and the gas in the battery plate production process enters the air inlet channel 312 through the opened solenoid valve 5. The gas enters the steel ring 32 through the air inlet channel 312 and the flow channel 38 on the steel ring 32, and the gas flows in the gap between the limit column 37 and the inner ring of the steel ring 32, and the gas blows the steel ball 33 to rotate in the gap. The steel ball 33 rotates in the annular gap between the steel ring 32 and the limit column 37 to generate centrifugal force, and the steel ball 33 continuously hits the steel ring 32 to transmit its amplitude to the adjustment spring 43 connected to the surface of the steel ring 32, and the adjustment spring 43 itself transmits the amplitude to the transmission plate 44, and the transmission plate 44 itself transmits the amplitude to the vibration spring 45, and the vibration spring 45 drives the connected vibration plate 46 to vibrate. The vibration plate 46 contacts the surface of the mixing barrel and vibrates it, so that the material in the mixing barrel body 1 is shaken off due to the vibration, thereby preventing the material in the mixing barrel from adhering to the inner wall and affecting the discharge efficiency. The vibration of the vibration structure 3 can be adjusted by the adjustment structure 4. By rotating the transmission rod, the active bevel gear 411 at one end of the transmission rod indirectly drives the transmission bevel gear 410 to rotate, so that the screw rod 49 rotates in the setting groove 48. The limit plate 47 on the surface of the screw rod 49 is subjected to the force of the thread and is slidably limited in the limit groove 42. During the sliding process, the connected transfer plate 44 is driven to move, and the transfer plate 44 adjusts the length of the transfer springs and the vibration spring 45 on both sides to change its elastic potential energy. The transfer spring is compressed, the length of the transfer spring is shortened, and the distance between the transfer plate 44 and the steel ring 32 is reduced, so that the vibration of the steel ring 32 can be effectively transmitted to the transfer plate 44, reducing the energy loss of the amplitude. Since the damping of the vibration spring 45 is much greater than that of the transmission spring, the efficiency of the vibration spring 45 in transmitting the amplitude is almost unchanged when the same length is changed, so the magnitude of the vibration can be changed by changing the distance of the transmission plate 44. During the movement of the transmission plate 44 and the limit plate 47, one end of the limit plate 47 extends out from the connecting groove 413, and the limit groove 42 can be compared with the scale on the surface of the vibration housing 31, so as to accurately judge the vibration intensity of each vibration structure 3.

[0037] Among them, two rows of vibration structures 3 are arranged on the surface of the mixing barrel body 1, and the vibration structures 3 in the same row are arranged in the same form, and the air inlet channels 312 are located on the same side of the air outlet channels 313; the vibration structures 3 in different rows are arranged in opposite forms, and the relative positions of the air inlet channels 312 and the air outlet channels 313 in the vibration shells 31 in different rows are opposite; the steel balls 33 in the two rows of vibration structures 3 rotate in opposite directions, so that the vibration force on the materials in the mixing barrel body 1 is uniform.

[0038] Working principle of the present invention: A vibrator for auxiliary flow of a battery plate mixing barrel of the present invention is provided with a vibration structure 3, and a steel ring 32 and a steel ball 33 are rotatably provided in a vibration shell 31 of the vibration structure 3. The steel ball 33 is acted upon by the external circulating air and moves back and forth in the circular gap between the steel ring 32 and the limiting column 37, thereby continuously impacting the steel ring 32 to generate centrifugal force, and the centrifugal force is transmitted to the vibration plate 46 through the transmission spring. The vibration plate 46 continuously vibrates the surface of the mixing barrel to cause the material attached to the mixing barrel body 1 to fall off, thereby improving the discharge efficiency; the circulating air in the battery production process is used to vibrate the mixing barrel body 1, thereby improving the energy utilization efficiency and reducing the production cost; by providing an adjustment structure 4, the transmission shaft 412 of the adjustment structure 4 rotates , indirectly driving the transfer plate 44 to move in the adjustment groove 41; the transfer plate 44 drives the transfer springs and vibration springs 45 on both sides to expand and contract. When the transfer spring is compressed, the distance between the transfer plate 44 and the steel ring 32 becomes smaller, so that the amplitude in the steel ring 32 is more effectively transmitted to the transfer plate 44, and the large damping vibration spring 45 connected to one side of the transfer plate 44 has almost no reduction in the efficiency of transmitting the amplitude after the extension length changes, thereby controlling the efficiency of transmitting the amplitude of the vibration structure 3 through the transmission shaft 412; by setting a connecting groove 413, one end of the limit plate 47 extends out of the connecting groove 413, and the scale on the surface of the vibration shell 31 is compared with the position of the limit plate 47, so as to determine the vibration size of each vibration structure 3 and accurately control the surface vibration of the mixing barrel body 1.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
