The positioning bolt 320 is engaged with the kidney-shaped hole 310, so as to adjust the relative position between the side guide plate 300 and the air supply base 100, thereby controlling and changing the size of the air outlet 301, and the specific operation mode is described below.

In the present embodiment, as shown in fig. 2, the supporting plates 210 are disposed at two ends of the guiding capping member 200, the supporting plates 210 and the side guiding plates 300 are respectively connected end to form a rectangular box body with an upper opening and a lower opening, the guiding capping member 200 is disposed on the top surface of the rectangular box body, and the blowing base 100 is disposed on the bottom surface of the rectangular box body. As shown in fig. 4, in operation, a dry airflow from the external coater firstly passes through the air supply base 100, enters the rectangular box, and then is blown out from the air outlet 301 to dry the battery pole piece located above the guide capping piece 200.

In the present embodiment, as shown in fig. 5 and 6, the positioning bolt 320 includes a baffle portion 322 and a rod portion 323, the baffle portion 322 is circular, the diameter of the baffle portion 322 is larger than the size of the kidney-shaped hole 310, the diameter of the rod portion 323 is smaller than the size of the kidney-shaped hole 310, and the indication mark 321 is provided on the outer surface of the baffle portion 322. Preferably, the rod 323 is provided with a screw thread, and the air supply base 100 is provided with a screw hole (not shown) matching with the rod. When the worker tightens the positioning bolt 320, the blocking plate 322 presses against the edge of the kidney hole 310 of the side guide 300, so that the side guide 300 can be fixedly mounted on the blower base 100 by the friction force generated by the pressing of the positioning bolt 320.

In the present embodiment, as shown in fig. 7, the guide capping material 200 is provided with the air guide surface 220, the side guide 300 is provided with the guide surface 330 parallel to the air guide surface 220, and the air outlet 301 is formed between the air guide surface 220 and the guide surface 330.

Below, combine above-mentioned structure, right the utility model discloses a theory of operation of lower tuyere assembly 10 with adjustable air outlet amount of wind explains the explanation:

when the battery pole piece guide sealing device works, dry airflow blown out from an external coating machine firstly passes through the air supply base 100, then enters the rectangular box body, and is blown out from the air outlet 301 to dry the battery pole piece positioned above the guide sealing top piece 200;

when the air outlet 301 is adjusted as required, a worker needs to loosen the positioning bolt 320 first, so that the baffle portion 322 of the positioning bolt 320 does not press the edge of the waist-shaped hole 310 any more, and thus the side guide plate 300 can slide relative to the blower base 100 along the direction of the waist-shaped hole 310. In the sliding process of the side guide 300, the position of the air supply base 100 is fixed, and the position of the guide cover 200 connected to the air supply base 100 via the support plate 210 is also fixed. After sliding, the distance between air guide surface 220 and guide surface 330 changes, i.e., the size of outlet 301 changes (when the distance increases, outlet 301 increases, the air flow rate increases, and when the distance decreases, the opposite is true). In the adjusting process, the indication mark 321 of the positioning bolt 320 is matched with the scale 311, so that a worker can visually see the sliding distance of the side guide plate 300. After adjustment, the worker tightens the set bolt 320 again so that the baffle portion 322 presses the fixed-side guide plate 300 again. Of course, the worker needs to sequentially operate the plurality of positioning bolts 320 on the same side guide plate 300 until the side guide plate 300 moves a certain distance as a whole.

As shown in fig. 5 and 6, the indication mark 321 is provided on the baffle portion 322 of the positioning bolt 320, and the indication mark 321 is radial around the center of the baffle portion 322. Therefore, no matter how the positioning bolt 320 rotates, an indication mark 321 closest to the horizontal line is pointed to a specific scale on the scale 311 from the center of the positioning bolt 320, so that the worker can visually recognize the sliding distance of the side guide 300. Without the radial indicator 321, the worker can only visually observe a specific scale on the scale 311 to align with the positioning bolt 320, which may result in too large a difference in adjustment of the positioning bolts 320.

In this embodiment, as shown in fig. 7, the air guide surface 220 and the guide surface 330 are both inclined toward the center of the guide top cover 200, and the air outlet 301 is inclined upward. During operation, because the air outlets 301 on both sides all incline towards the center, when a battery pole piece passes through the upper part of the guide top sealing piece 200, the air flow blown out from the air outlets 301 can generate an upward lifting force on the pole piece, and the directions of the air flows are crossed, so that the stress of the pole piece can be balanced, and the pole piece is not easy to incline towards one side.

Preferably, as shown in fig. 7, the guide capper 200 is provided with an auxiliary guide surface 230, the auxiliary guide surface 230 and the inner wall of the side guide 300 form a trumpet-shaped drainage opening 302, and the drainage opening 302 is communicated with the air outlet 301. In operation, the air flow can be better guided by the air outlet 302 to be blown out from the air outlet 301.

Further, as shown in fig. 4, the side guide 300 is provided with an extension plate 340 at a bottom edge thereof opposite to the guide surface 330, the extension plate 340 being perpendicular to the plate surface of the side guide 300. In the adjustment process, after the staff unscrewed positioning bolt 320, the side guide plate 300 was lifted or pushed through the extension plate 340, the extension plate 340 provided the starting position of application of force for the staff, and because area of contact is big, can effectively avoid the staff by the edge fish tail of side guide plate 300.

In this embodiment, as shown in fig. 4, the air supply base 100 is a hollow structure, the air supply base 100 is provided with an air inlet 110 and a ventilation board 120, and the ventilation board 120 is provided with a plurality of through holes, and the through holes are uniformly distributed on the ventilation board 120 in an array manner. When the air supply device works, dry airflow blown out from an external coating machine enters the air supply base 100 from the air inlet 110, enters the rectangular box body through the ventilation plate 120, and is blown out from the air outlet 301 to dry a battery pole piece above the guide capping piece 200. During this period, the ventilation board 120 has the through holes distributed uniformly, so that when the dry air flow passes through the ventilation board 120, the air flow is more uniformly distributed on the whole ventilation board 120, and is not easily concentrated in the middle.

Preferably, as shown in fig. 2, stepped grooves 130 are provided at both ends of the air supply base 100, and the stepped grooves 130 are used for clamping and limiting the air supply base 100. During installation, a worker can conveniently and quickly position and install the air supply base 100 on the coating machine through the stepped groove 130; after installation, the stepped groove 130 and the clamping groove of the coater are clamped with each other, so that the air supply base 100 can be stably maintained at the current position.
