Description

Technical Field

[0001] The invention belongs to the technical field of auxiliary devices for electrode extruders, and in particular relates to an electrode speed-measuring, fixed-length synchronous shearing device. Background Art

[0002] In the extrusion production process of the electrode, after the electrode is extruded from the extruder to a set length, it is sheared by a shearing machine to obtain a finished electrode of a specified length. Therefore, the electrode extruder is usually equipped with an auxiliary device for electrode fixed length shearing. For example, in the prior art of Chinese patent application No. 201410129888.9, an electrode fixed length device is disclosed, which is installed above the discharge trough. When the electrode reaches the specified length, a signal is sent to shear the electrode.

[0003] However, the common problems existing in the prior art are: 1. It can only detect the length of the electrode but not the speed of the electrode, so "synchronous shearing" cannot be achieved. It is necessary to stop extrusion and continue extrusion after shearing, which affects the production efficiency of the electrode; 2. When producing electrodes of different length specifications, it is necessary to manually adjust the position of the proximity switch of the electrode length-fixing device, which is cumbersome to operate and has low length detection accuracy. Summary of the invention

[0004] In order to solve the above technical problems existing in the prior art, the present invention provides an electrode speed-measuring and length-fixing synchronous shearing device, which is installed at the discharge end of the electrode extruder, and includes a synchronous shearing mechanism and an electrode speed-measuring and length-fixing mechanism, wherein:

[0005] The synchronous shearing mechanism comprises a frame, a scissor frame arranged on the frame, a first oil cylinder arranged on the frame to drive the scissor frame, two scissor blades installed inside the scissor frame, and two second oil cylinders arranged on the frame to drive one of the scissor blades respectively;

[0006] The electrode speed measurement and fixed length mechanism includes a friction wheel, a bearing, a shaft, a coupling, an encoder, a connecting plate, a spring, a fixed plate, a guide rod, an adjusting screw, and a bracket. The bracket is installed on the frame, the adjusting screw and the guide rod are installed on the fixed plate through the bracket, the spring is installed between the fixed plate and the connecting plate, a pair of bearings are installed at the lower part of the connecting plate, the shaft is installed between the pair of bearings, the friction wheel is sleeved on the shaft, and the encoder is connected to one end of the shaft through the coupling.

[0007] Furthermore, in the above-mentioned electrode speed-measuring and fixed-length synchronous shearing device, the hydraulic oil circuit of the first oil cylinder is controlled by a proportional valve to drive the scissors frame to move forward along the extrusion direction of the electrode or backward in the opposite direction of the extrusion direction of the electrode on the linear guide rail.

[0008] Furthermore, in the above-mentioned electrode speed-measuring fixed-length synchronous shearing device, the second oil cylinder drives the two scissor blades to move toward each other or away from each other.

[0009] Furthermore, in the above-mentioned electrode speed-measuring fixed-length synchronous shearing device, the number of the guide rods is two, which are respectively located on both sides of the adjusting screw.

[0010] The electrode speed-measuring fixed-length synchronous shearing device of the present invention has the following advantages and beneficial effects:

[0011] The device detects the extrusion speed and length of the electrode through the electrode speed measuring and length fixing mechanism, and cooperates with the synchronous shearing mechanism to realize synchronous shearing and fixed-length shearing of the electrode, thereby realizing uninterrupted extrusion and continuous extrusion production, and significantly improving the production efficiency of the electrode;

[0012] When producing electrodes of different lengths, there is no need to make any adjustments to the device; when producing electrodes of different diameters, only the adjusting screw needs to be adaptively adjusted. The operation is simple, and since the friction wheel can always maintain close contact with the electrode, the detection accuracy of the electrode extrusion speed and extrusion length is higher.

[0018] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the electrode speed-measuring and length-fixing synchronous shearing device of the present invention is installed at the discharge end of the electrode extruder, and includes a synchronous shearing mechanism 10 and an electrode speed-measuring and length-fixing mechanism 20 , wherein the synchronous shearing mechanism 10 is located between the electrode extruder and the electrode speed-measuring and length-fixing mechanism 20 .

[0020] The synchronous shearing mechanism 10 includes a frame 11, a scissor frame 12 disposed on the frame 11, a first oil cylinder 14 disposed on the frame 11 to drive the scissor frame 12, two scissor blades 13 installed inside the scissor frame 12, and two second oil cylinders 15 disposed on the frame 11 to drive each scissor blade 13. The hydraulic oil circuit of the first oil cylinder 14 is controlled by a proportional valve to drive the scissor frame 12 to move forward (in the extrusion direction of the electrode 100) on the linear guide rail. Figure 2 or moves backward (in the direction opposite to the extrusion direction of the electrode 100) Figure 2 The second oil cylinder 15 drives the two scissor blades 13 to move toward each other or away from each other to achieve the actions of "cutting" and "resetting".

[0021] The electrode speed measurement and fixed length mechanism 20 includes a friction wheel 21, a bearing 22, a shaft 23, a coupling 24, an encoder 25, a connecting plate 26, a spring 27, a fixing plate 28, a guide rod 29, an adjusting screw 30, and a bracket 31. The bracket 31 is mounted on the frame 11 of the synchronous shearing mechanism 10, the adjusting screw 30 and the guide rod 29 are installed on the fixing plate 28 through the bracket 31, the spring 27 is installed between the fixing plate 28 and the connecting plate 26, a pair of bearings 22 are installed at the lower part of the connecting plate 26, the shaft 23 is installed between the pair of bearings 22, the friction wheel 21 is sleeved on the shaft 23, and the encoder 25 is connected to one end of the shaft 23 through the coupling 24.

[0022] The working process of the electrode speed-measuring fixed-length synchronous shearing device of the present invention is as follows:

[0023] When the electrode 100 is extruded to a certain length, it contacts the friction wheel 21, driving the friction wheel 21 to rotate. The encoder 25 rotates with the friction wheel 21 through the shaft 23. The extrusion speed v of the electrode 100 can be obtained through the data of the encoder 25, and the extrusion length of the electrode 100 can be measured in real time based on the extrusion speed v of the electrode 100, that is, the extrusion length of the electrode 100 = the distance between the scissor blade 13 and the friction wheel 21 + the extrusion speed v × the extrusion time t;

[0024] When the extrusion length of the electrode 100 reaches a set value, the first oil cylinder 14 drives the scissor frame 12 to move forward along the extrusion direction of the electrode 100 at a speed equal to the extrusion speed v of the electrode 100 under the control of the proportional valve. At the same time, the second oil cylinder 15 drives the two scissor blades 13 to approach each other so that the scissor blades 13 are closed to shear the electrode 100.

[0025] During the operation of the electrode speed-measurement fixed-length synchronous shearing device of the present invention, since the scissor blades 13 are installed inside the scissor frame 12, the scissor blades 13 move forward synchronously with the scissor frame 12 at a speed equal to the extrusion speed v of the electrode 100, thereby achieving synchronous fixed-length shearing of the electrode 100.

[0026] In the electrode speed-measuring and fixed-length synchronous shearing device of the present invention, the spring 27 can ensure that the friction wheel 21 always maintains close contact with the electrode 100, thereby ensuring the accuracy of the data of the encoder 25 and the higher detection accuracy of the extrusion speed and extrusion length of the electrode 100.

[0027] In the electrode speed-measuring and fixed-length synchronous shearing device of the present invention, when producing electrodes of different diameter specifications, the adjusting screw 30 is adjusted so that the fixing plate 28 is adjusted up and down accordingly relative to the bracket 31 under the guidance of the guide rod 29, thereby ensuring that the friction wheel 21 maintains close contact with the electrode, thereby realizing accurate detection of the electrode extrusion speed and extrusion length.

[0028] Preferably, there are two guide rods 29, which are respectively located on both sides of the adjusting screw 30 to improve the adjustment accuracy of the fixing plate 28, thereby further ensuring that the friction wheel 21 is in close contact with the electrode, thereby ensuring the detection accuracy of the electrode extrusion speed and extrusion length.

[0029] In summary, compared with the prior art, the electrode speed-measuring fixed-length synchronous shearing device of the present invention has the following advantages and beneficial effects:

[0030] The device can detect the extrusion speed and extrusion length of the electrode through the electrode speed measuring and length fixing mechanism, and cooperate with the synchronous shearing mechanism to realize synchronous shearing and fixed-length shearing of the electrode, thereby realizing uninterrupted extrusion and continuous extrusion production, and significantly improving the production efficiency of the electrode;

[0031] When producing electrodes of different lengths, there is no need to make any adjustments to the device. Moreover, when producing electrodes of different diameters, only the adjusting screw needs to be adaptively adjusted. The operation is simple, and since the friction wheel can always maintain close contact with the electrode, the detection accuracy of the electrode extrusion speed and extrusion length is higher.
