[0024] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] like Figures 1 to 8 As shown, the battery electrode oven of the embodiment of the utility model comprises an oven body 1, an upper hull 2 ​​is arranged in the oven body, an upper wind box 3 is arranged at the bottom of the upper hull, a gear transmission mechanism for controlling the lifting of the upper hull is arranged at the upper end of the oven body 1, two gears 7 with opposite tooth surfaces arranged in the gear transmission mechanism, a worm gear mechanism is arranged between the two gears, the centers of the two gears are respectively connected to the upper end of the upper hull through a connecting pull rod 9, and the two worm gear mechanisms include two worms 6 arranged in parallel, each worm 6 is meshed with one of the gears 7, and the two worms 6 are connected to a transmission shaft 16 through a transmission gear.

[0026] In the present application, multiple sets of simple gear structures and worm structures are used to reduce the required driving force. By rotating the gear 7, the power can be transmitted to the pull rod 9 that cooperates with it, so that the pull rod 9 can be lifted and lowered, thereby adjusting the upper hull up and down, and a single person can operate it. Since multiple sets of gears are used to form a gear structure, the structure is simple, the labor is greatly reduced, and a single person can complete all the work; thus, the height of the upper hull can be adjusted, solving the defects of the existing pole piece oven, which has a complex structure for adjusting the height of the upper hull, has many structural parts, and is not conducive to real-time operation by a single person.

[0027] The transmission shaft 16 is located between the two worm gears 6 . More preferably, the two worm gears are symmetrically arranged on both sides of the transmission shaft.

[0028] In order to facilitate transmission control, in the present application, a driving gear 5 is arranged near both ends of the transmission shaft 16, and a driven gear 10 matching the driving gear is installed on each of the worm gears 6. By configuring the driving gear and the driven gear in this way, when the transmission shaft is driven to rotate, the two worm gears can be synchronously controlled to rotate, thereby synchronously controlling the rotation of the two gears, thereby controlling the lifting and lowering of the upper hull.

[0029] In order to conveniently control the rotation of the transmission shaft, a turntable 11 is connected to one end of the transmission shaft 16 . Furthermore, a hand crank 12 is installed on the outer side of the turntable 11 to facilitate the rotation of the transmission shaft 16 .

[0030] In a preferred embodiment, the pull rod 9 is a T-shaped rod, and the horizontal rod 92 of each pull rod is connected to the upper end of the upper hull through two fixed points, and specifically can be connected to a connecting seat 13 fixed at the upper end of the upper hull. The vertical rod 91 of the pull rod 9 is an externally threaded rod, which passes through the top plate of the oven body 1 and is connected to the corresponding center hole of the gear 7, wherein the pull rod and the center hole of the gear are threadedly connected.

[0031] Among them, in the present application, an air outlet 19 is opened at the bottom 17 of the upper hull, and the size of the air outlet matches the two sides of the upper wind box 3 to ensure that the upper wind box does not leak air when moving left and right. A slide 14 is arranged on the outer side of the lower part of the upper hull. The cross-section of the slide is a T-shaped structure. A matching slide buckle 8 is arranged in the slide, and the slide buckle 8 can move freely on the slide. The upper wind box is installed at the position of the air outlet at the bottom of the upper hull through the slide buckle. In the present application, the connection of the upper wind box with the slide buckle 8 can control the left and right position adjustment of the upper wind box 3 at the bottom of the upper hull. Since the upper wind box is connected to the upper hull on one side by the slide buckle 8, it is convenient to remove the upper wind box, thereby solving the problem of difficulty in disassembly and assembly of the upper wind box.

[0032] A more preferred embodiment is that at the other end opposite to the slide 14, a limiting groove 15 is arranged at the bottom of the upper hull, the first end 34 of the upper wind box is placed in the limiting groove 15, and the opposite second end 35 is connected to the bottom of the upper hull 1 through the slider 8 on the slide.

[0033] In one embodiment, the slide buckle 8 includes an L-shaped plate 83, and the inner surface of the side plate of the L-shaped plate 83 facing the slide has a T-shaped portion 82 that cooperates with the slide; a limiting gap 84 is formed between the T-shaped portion and the bottom plate of the L-shaped plate located at the bottom of the slide for inserting and installing the side edge (i.e., the second end 35) of the upper wind box.

[0034] Furthermore, a knob 81 is arranged in the threaded hole on the side plate of the L-shaped plate 83 facing the slideway to lock the slider 8 and the slideway 14 .

[0035] In one embodiment, the upper wind box 3 is a T-shaped structure, not a cube structure, and has a rectangular wind box body 31. The bottom of the wind box body has a plurality of air outlets 33, and both sides of the upper end of the wind box body have symmetrical horizontal baffles 32, so that the upper end of the upper wind box can match the upper air outlet 18 on the bottom surface 17 of the upper hull, and the position of the upper wind box on the bottom surface of the upper hull can be adjusted left and right within a certain range to ensure that there is no air leakage.

[0036] In a preferred embodiment, there are two upper air outlets 18 on the upper hull bottom surface 17 , which are arranged relatively and spaced apart from each other. Correspondingly, there are two upper wind boxes, each of which is installed and fixed by a sliding buckle 8 .

[0037] The battery pole piece oven in the present application can adjust the upper hull height and the upper wind box position, and can adjust the upper wind box and the upper hull position at the same time, solving the problems of complex hull height adjustment structure, large number of structural parts, and difficulty in disassembling and assembling the wind box.
