For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] A capacitor powder preheating device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0031] Reference Figure 1 A capacitor powder preheating device according to an embodiment of the utility model comprises a heating mechanism and a conveying mechanism, wherein the heating mechanism comprises a box body 100, a heating chamber 110 connected to the inside of the box body 100, and a heater located in the heating chamber 110. A feeding channel 120 and a discharging channel 130 are respectively arranged on opposite sides of the box body 100. The feeding channel 120 accommodates a braided capacitor 140 moved from the outside of the box body 100 to pass through, and the discharging channel 130 accommodates a braided capacitor 140 moved from the inside of the box body 100 to pass through;

[0032] The conveying mechanism is used to convey the braided capacitor 140 in the box body 100, and includes a first conveying group and a second conveying group located inside the box body 100, and a heater is arranged between the first conveying group and the second conveying group.

[0033] Further, the heating chamber 110 has a first side wall and a second side wall. Figure 3The first side wall and the second side wall are arranged opposite to each other, the first conveying group includes a plurality of first conveying wheels 150 arranged horizontally, and the plurality of first conveying wheels 150 are distributed in a straight line along the edge of the first side wall, the second conveying group includes a plurality of second conveying wheels 160 arranged horizontally, and the plurality of second conveying wheels 160 are distributed in a straight line along the edge of the second side wall, the number of the first conveying wheels 150 is one more than the number of the second conveying wheels 160, and the braided capacitor 140 alternately bypasses the first conveying wheel 150 and the second conveying wheel 160.

[0034] It should be noted that the braided capacitor 140 includes a braided body and a plurality of capacitor bodies arranged along the length direction of the braided body. The braided body is provided with a plurality of through holes. The radial outer surfaces of the first conveying wheel 150 and the second conveying wheel 160 are provided with pins, and the pins are inserted into the through holes. Thus, when the first conveying wheel 150 and the second conveying wheel 160 rotate, the pins can pull the braided capacitor 140 to move.

[0035] In some embodiments of the present invention, the feed channel 120 and the discharge channel 130 are both disposed close to the first conveying wheel 150 .

[0036] Therefore, the braided capacitor 140 enters the interior of the box 100 through the feed channel 120, so that the braided capacitor 140 line bypasses the first conveying wheel 150, then bypasses the second conveying wheel 160, and finally the braided capacitor 140 line bypasses the first conveying wheel 150 and moves out of the box 100 through the discharge channel 130, which is beneficial to increase the overlapping position of the braided capacitor 140 and the heater.

[0037] In some embodiments of the present invention, a groove body 170 is disposed at the bottom of the box body 100 . The groove body 170 is communicated with the box body 100 , and the inner cavity of the groove body 170 forms the heating cavity 110 .

[0038] Therefore, the additional groove 170 of the housing 100 can increase the internal space of the housing 100 and prevent the braided capacitor 140 from interfering with the heater during the movement of the housing 100 .

[0039] In some embodiments of the present invention, a cover plate 180 is disposed on the top of the tank body 170 , and the cover plate 180 is provided with a plurality of air guide holes 310 , and the air guide holes 310 are used to guide heat from the inside of the tank body 170 into the inside of the box body 100 .

[0040] It can be understood that the cover 180 can block the internal space of the slot 170 to prevent the braided capacitor 140 from falling off and onto the electric heater during the movement of the box 100. At the same time, the air guide hole 310 can guide the heat from the inside of the slot 170 into the inside of the box 100, making the heat inside the box 100 more uniform.

[0041] Specifically, refer to Figure 2The heater has at least two U-shaped heating rods 190 , and the at least two U-shaped heating rods 190 are arranged side by side, thereby increasing the overlapping position of the heater and the braided capacitor 140 .

[0042] In some embodiments of the present invention, a flip cover 200 is disposed on the top of the box body 100 , and the flip cover 200 forms the top wall of the box body 100 .

[0043] Therefore, the flip cover 200 is flipped upwards to open the interior of the box body 100, making it convenient to inspect the heater and the conveying mechanism, thereby greatly reducing the difficulty of inspection.

[0044] In some embodiments of the present invention, referring to Figure 1 The box body 100 is provided with a vertical rod 210, a swing rod 220 is hinged on the top of the vertical rod 210, a cylinder 230 is provided between the free end of the swing rod 220 and the flip cover 200, one end of the cylinder 230 is hinged to the swing rod 220, and the other end of the cylinder 230 is hinged to the flip cover 200.

[0045] It is understandable that the cylinder 230 is used to drive the swing rod 220 to swing, and the flip cover 200 can be flipped upward or downward at the same time, so that there is no need to manually flip the flip cover 200, which reduces the difficulty of opening and closing the flip cover 200.

[0046] In some embodiments of the present invention, referring to Figure 4 The flip cover 200 is provided with a sealing gasket 240 , and the flip cover 200 is in sealing contact with the top of the box body 100 through the sealing gasket 240 . Therefore, the sealing gasket 240 can reduce the heat escape from the gap between the flip cover 200 and the box body 100 .

[0047] In some embodiments of the present invention, the flip cover 200 has a frame 250 and a transparent glass plate 260 disposed in the frame 250 , so that the staff can observe the movement of the braided capacitor 140 inside the box 100 through the transparent glass plate 260 .

[0048] In some embodiments of the present invention, the first conveying group also includes a first transmission shaft 270 and a second transmission shaft 280. The first transmission shaft 270 is coaxially arranged on the first conveying wheel 150. The first transmission shaft 270 is provided with a first bevel gear 290, and the second transmission shaft 280 is provided with a second bevel gear 300. The first bevel gear 290 and the second bevel gear 300 are meshingly arranged.

[0049] It should be noted that a motor can be used to drive the second transmission shaft 280 to rotate, and the first bevel gear 290 and the second bevel gear 300 are meshed and transmitted, so that the first transmission shaft 270 drives the first conveying wheel 150 to rotate, so that the first conveying wheel 150 can convey the braided capacitor 140.

[0050] Therefore, this embodiment has the following effects:

[0051] 1. The utility model is provided with a box body 100, a heating chamber 110 and a heater. The braided capacitor 140 enters the inside of the box body 100 from the discharge channel 130. The heater generates hot air, and the hot air enters the inside of the box body 100 from the heating chamber 110. The hot air in the box body 100 can preheat the braided capacitor 140 to avoid interference between the braided capacitor 140 and the heater. In addition, the inner cavity of the box body 100 is a closed space, which can efficiently heat the braided capacitor 140.

[0052] 2. The utility model provides a plurality of first conveying wheels 150 and second conveying wheels 160, and a heater is provided between the first conveying wheels 150 and the second conveying wheels 160. The braided capacitor 140 alternately bypasses the first conveying wheels 150 and the second conveying wheels 160, so that the overlapping position of the braided capacitor 140 and the heater is increased, and the moving stroke of the braided capacitor 140 inside the box 100 is greatly increased, which also prolongs the heating time of the braided capacitor 140, makes the capacitor chip preheated evenly, and has a better preheating effect, which is conducive to the uniform coating of the packaging powder on the capacitor chip.

[0054] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
