Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0032] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Reference Figures 1 to 4 As shown, some embodiments of the present invention provide a pole piece threading device 2, including: a clamping component 21, a first sliding component 22 and a second sliding component 23, the clamping component 21 is provided with a threading gap, and the threading gap is used for threading the pole piece; the first sliding component 22 is provided at one end of the clamping component 21; the first sliding component 22 and the second sliding component 23 are fixedly connected, and the first sliding component 22 and the second sliding component 23 are enclosed to form a sliding channel, and the sliding channel is suitable for cooperating and connecting with the channel steel 3 at the edge of the wind nozzle, and the first sliding component 22 and the second sliding component 23 are suitable for sliding along the length direction of the channel steel 3, so that the clamping component 21 drives the pole piece to slide.

[0034] Specifically, the pole piece is inserted into the strip-threading gap, and the clamping assembly 21 is suitable for clamping the pole piece. A first sliding assembly 22 is provided at one end of the clamping assembly 21. The first sliding assembly 22 and the second sliding assembly 23 are fixedly connected to enclose and form a sliding channel. The sliding channel is connected to the channel steel 3 at the edge of the air nozzle. Under the action of external force, the first sliding assembly 22 and the second sliding assembly 23 are suitable for sliding along the length direction of the steel channel, so that the clamping assembly 21 drives the pole piece to slide. The pole piece strip-threading device 2 has a simple structure. The installation of the pole piece strip-threading device 2 is achieved by connecting the sliding channel with the channel steel 3 at the edge of the air nozzle. The original channel steel 3 is used for guidance, thereby reducing the setting of the guide parts, overcoming the problem that the gap between the air nozzles in the oven 1 is too narrow to install the guide parts, and effectively reducing costs.

[0035] Specifically, the first sliding assembly 22 and the second sliding assembly 23 are manually driven by a purely mechanical structure, or are driven electrically or pneumatically. After the electrode is fixed to the electrode threading device 2, the first sliding assembly 22 and the second sliding assembly 23 are manually pushed to move along the length of the channel steel 3. The clamping assembly 21 pulls the electrode to complete the threading, and the air nozzle realizes the drying of the electrode.

[0036] Reference Figure 4 As shown, in some embodiments of the present invention, the clamping assembly 21 includes a first clamping plate 211, a second clamping plate 212 and at least two first fasteners 213. The first clamping plate 211 and the second clamping plate 212 are arranged up and down and enclosed to form a belt-threading gap. The two first fasteners 213 are respectively arranged at both ends of the second clamping plate 212. The first fasteners 213 pass through the first clamping plate 211 and the second clamping plate 212 to clamp and fix the first clamping plate 211 and the second clamping plate 212. The first sliding assembly 22 is arranged at one end of the first clamping plate 211.

[0037] Specifically, the first clamping plate 211 and the second clamping plate 212 are arranged vertically, and two first fasteners 213 are provided at both ends of the second clamping plate 212. After the electrode is inserted into the gap, the two first fasteners 213 are tightened to clamp the first clamping plate 211 and the second clamping plate 212 together, thereby pressing the electrode. The first fasteners 213 are screws. The second clamping plate 212 is made of polytetrafluoroethylene, which is soft and strong, and can compress the electrode while preventing damage to the electrode.

[0038] Reference Figure 3 and Figure 4As shown, in some embodiments of the present invention, the first sliding component 22 includes a connecting plate 221, and a rolling member 222 provided on the connecting plate 221, the connecting plate 221 includes a first horizontal portion 2211 and a first vertical portion 2212 connected to each other, the upper end surface of the first horizontal portion 2211 is fixedly connected to the clamping component 21, and the rolling member 222 is rotatably provided on one side end surface of the first vertical portion 2212, and the axis of the rolling member 222 is perpendicular to the first vertical portion 2212.

[0039] Specifically, the connecting plate 221 has an L-shaped structure, comprising a first horizontal portion 2211 and a second horizontal portion 2321 connected to each other. The upper end surface of the first horizontal portion 2211 is fixedly connected to the lower end surface of the first clamping plate 211. The first horizontal portion 2211 and the first clamping plate 211 are parallel to each other, and the first vertical portion 2212 is perpendicular to the first horizontal portion 2211. The rolling member 222 is rotatably disposed on a side surface of the first vertical portion 2212 to be in rolling connection with the channel steel 3. The axial direction of the rolling member 222 is perpendicular to the first vertical portion 2212, and the rolling member 222 is fixed along the axial direction. The rolling member 222 is a pulley.

[0040] In some embodiments of the present invention, the second sliding assembly 23 includes a slider 231 and a baffle 232 connected to each other, the slider 231 is located below the rolling member 222, the slider 231 and the rolling member 222 form a sliding channel, and the baffle 232 is located on one side of the rolling member 222 and is connected to the rolling member 222.

[0041] Specifically, the slider 231 and the rolling member 222 are arranged at intervals, and the slider 231 is located below the rolling member 222. The slider 231 and the rolling member 222 enclose a sliding channel, and the baffle 232 is located on one side of the rolling member 222 and is connected to the rolling member 222, thereby realizing a fixed connection between the first sliding component 22 and the second sliding component 23. The channel steel 3 is partially placed in the sliding channel, so that when external force is applied to the first sliding component 22 and / or the second sliding component, the pole piece is driven to slide along the length direction of the channel steel 3 under the cooperation of the rolling member 222 and the slider 231 and the channel steel 3.

[0042] It is understandable that the channel steel 3 is a C-shaped channel steel or an I-shaped channel steel, that is, the channel steel 3 has at least one horizontal section, the rolling member 222 is rollingly connected to the upper end surface of the horizontal section, and the slider 231 is slidingly connected to the lower end surface of the horizontal section.

[0043] Reference Figure 5 and Figure 6As shown, in some embodiments of the present invention, a waist-shaped hole 2323 is provided on the baffle 232, and the length direction of the waist-shaped hole 2323 is set in the vertical direction. The second sliding component 23 also includes a second fastener 233, and the second fastener 233 is passed through the waist-shaped hole 2323 to be connected to the rolling member 222. The second fastener 233 can slide along the length direction of the waist-shaped hole 2323 to be suitable for adjusting the width of the sliding channel.

[0044] Specifically, a waist-shaped hole 2323 is provided on the baffle 232. The waist-shaped hole 2323 is located opposite to the rolling element 222, and the length of the waist-shaped hole 2323 is arranged along the vertical direction. The second fastener 233 is inserted into the waist-shaped hole 2323 to connect with the rolling element 222. When the position of the second fastener 233 on the waist-shaped hole 2323 is adjusted, the height of the slider 231 is adjusted, and the width of the sliding channel is adjusted to adjust the damping. Specifically, when the slider 231 moves upward, the width of the sliding channel decreases, thereby increasing the pressure of the slider 231 and the rolling element 222 on the channel steel 3, increasing the sliding damping, and increasing the external driving force required for the pole piece threading device 2 to slide. When the slider 231 moves downward, the width of the sliding channel increases, the pressure of the slider 231 and the rolling element 222 on the channel steel 3 decreases, reducing the sliding damping, and reducing the external driving force required for the pole piece threading device 2 to slide. It is understood that two rolling members 222 are provided, and the number of rolling members 222 is consistent with the number of waist-shaped holes 2323. The spacing between the two rolling members 222 is equal to the spacing between the two waist-shaped holes 2323. The two rolling members 222 are provided to ensure force balance and improve the stability of the structure.

[0045] It is understandable that the second fastener 233 is a screw, so as to facilitate disassembly and improve disassembly efficiency. When the wear between the slider 231, the rolling element and the channel steel 3 is too large, the second fastener 233 can be removed to achieve quick replacement and assembly.

[0046] In some embodiments of the present invention, the end surface edge of the slider 231 close to the sliding channel is chamfered.

[0047] On the side close to the sliding channel, the end face edge of the slider 231 is chamfered to reduce the contact area between the slider 231 and the channel steel 3 and reduce sliding friction.

[0048] It is understandable that the slider 231 is made of polytetrafluoroethylene to avoid the generation of iron filings when the slider 231 rubs against the channel steel 3. After the iron filings enter the air duct, they are likely to collide with components such as the fan impeller, thereby generating sparks, thereby increasing the risk of N-methylpyrrolidone (NMP) gas explosion.

[0049] In some embodiments of the present invention, the right end surface of the slider 231 is provided with a mounting groove 2312 in the horizontal direction, the baffle 232 includes a second horizontal portion 2321 placed in the mounting groove 2312, and a second vertical portion 2322 suitable for abutting against the rolling member 222, the lower end surface of the slider 231 is penetrated by a first mounting hole 2311 from bottom to top, the second horizontal portion 2321 is provided with a second mounting hole 2324, and the second sliding assembly 23 also includes a fixing member, which is penetrated by the first mounting hole 2311 and the second mounting hole 2324 to be suitable for fixing the slider 231 and the baffle 232 to be fixedly connected.

[0050] Specifically, the baffle 232 includes a second horizontal portion 2321 and a second vertical portion 2322 connected to each other, wherein a mounting groove 2312 is arranged in the horizontal direction on the right end face of the slider 231, and the second horizontal portion 2321 is passed through the mounting groove 2312. A first mounting hole 2311 is opened from bottom to top on the lower end face of the slider 231, and a second mounting hole 2324 is opened on the second horizontal portion 2321. The first mounting hole 2311 and the second mounting hole 2324 are arranged with equal diameter and coaxiality, so that when the fixing piece is passed through the first mounting hole 2311 and the second mounting hole 2324, the slider 231 and the baffle 232 are fixedly connected. It can be understood that the first mounting hole 2311 is a blind hole, and the first mounting hole 2311 / the second mounting hole 2324 are provided with an internal thread, and the fixing piece is a bolt.

[0051] Reference Figure 2 and Figure 7 As shown, an oven 1 mechanism includes: a first air nozzle, a second air nozzle and a pole piece threading device 2; a pole piece gap is provided between the first air nozzle and the second air nozzle, and steel grooves are provided at both ends of the first air nozzle and the second air nozzle; the pole piece threading device 2 is provided in the pole piece gap, and one end of the pole piece threading device 2 is slidably connected to any channel steel 3 and is suitable for sliding along the length direction of the channel steel 3.

[0052] Specifically, the electrode stripping device 2 is disposed in the electrode gap between the first and second gas nozzles. The electrode stripping device 2 is slidably connected to the channel steel 3 and is adapted to slide along the length of the channel steel 3 to drive the electrode to slide, thereby drying the electrode. The electrode stripping device 2 in the drying oven 1 utilizes the existing channel steel 3 for guidance, thereby reducing the need for guide parts, simplifying the structure, and effectively reducing costs.

[0053] It can be understood that the first air nozzle and the second air nozzle are spaced apart in the upper and lower parts to form a pole piece gap, the pole piece threading device 2 is arranged in the pole piece gap, the channel steel 3 is arranged at both ends of the first air nozzle and the second air nozzle to be suitable for fixing the first air nozzle and the second air nozzle, and the pole piece threading device 2 is slidably connected to the channel steel 3, thereby realizing sliding guidance through the channel steel 3.

[0054] Reference Figure 7and Figure 8 As shown, in some embodiments of the present invention, the oven 1 structure includes several oven sections 1, and a connecting assembly 4 arranged between two adjacent oven sections 1. A first air nozzle and a second air nozzle are provided in the oven 1. The connecting assembly 4 includes a connecting block 41 and a connecting plate 42 fixedly connected to the connecting block 41. The connecting block 41 is fixedly connected to the ends of two adjacent channel steels 3.
