Description

Technical Field

[0001] This application belongs to the field of electromagnetic roll heating, and particularly relates to an independent servo drive mechanism for the main over-roll. Background Art

[0002] With the development of the new energy battery industry, the use of electromagnetic roll heating has become an industry trend. Electromagnetic roll heating is a technology that uses the principle of electromagnetic induction to heat metal objects. It has a fast heating speed, a high heating temperature, and high temperature control accuracy, making it the first choice in the industry. The pole roll is a main component of a lithium battery, so its performance directly affects the quality of the battery. During the raw material and processing of the pole roll, it is easy to contain moisture, and high moisture has a certain impact on the quality of the battery. Therefore, certain technologies are needed to quickly remove the moisture and control it within a certain standard range. Electromagnetic roll heating is an efficient heating technology and the most advanced heating method in the industry. Combined with other technologies, it can achieve the rapid removal of moisture from the pole roll. The wound pole roll is transported to the electromagnetic heating roll through a pay-off mechanism. When the pole roll is released from the pay-off reel, it will pass through an over-roll. The over-roll rotates to assist in the transportation of the pole roll, ensuring that the pole roll can smoothly and accurately enter the electromagnetic heating roll. In the prior art, both the over-roll and the electromagnetic heating roll are driven by a chain, the transmission process is cumbersome, the synchronism between the over-roll and the electromagnetic heating roll is poor, and pole roll breakage accidents are likely to occur. Summary of the Utility Model

[0003] Aiming at the problems existing in the prior art, the utility model provides an independent servo drive mechanism for the main over-roll, with independent transmission between the over-roll and the electromagnetic heating roll, canceling the traditional chain drive and reducing transmission redundancy.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A main over-roller independent servo drive mechanism is used to control the rotation of the over-roller and the electromagnetic heating roller. The over-roller and the electromagnetic heating roller are horizontally mounted between two parallel equipment vertical plates. Multiple groups of main over-roller independent servo drive mechanisms are distributed in the length direction of the equipment vertical plates. The main over-roller independent servo drive mechanism includes a power component one for providing power to the electromagnetic heating roller and a power component two for providing power to the over-roller. The power component one and the power component two are independently arranged. The pole coil enters from the over-roller and is then conveyed to the electromagnetic heating roller for heating. Leveling brackets are connected to both the power component two and the power component one. The power component one includes multiple upper synchronous belt wheels distributed on the upper part of the equipment vertical plate, an upper driving wheel connected to the upper synchronous belt wheels through the upper synchronous belt, a motor one connected to the upper driving wheel, lower synchronous belt wheels distributed on the lower part of the equipment vertical plate, and a lower driving wheel connected to the lower synchronous belt wheels through the lower synchronous belt. The upper driving wheel is coaxially connected to a helical gear one, and the lower driving wheel is coaxially connected to a helical gear two. The helical gear one meshes with the helical gear two. Under the action of the helical gear one and the helical gear two, the rotation directions of the upper synchronous belt wheels and the lower synchronous belt wheels are opposite.

[0006] Further, each upper synchronous belt wheel is connected to an electromagnetic heating roller arranged on the upper part of the equipment vertical plate, and each lower synchronous belt wheel is connected to an electromagnetic heating roller arranged on the lower part of the equipment vertical plate. The upper synchronous belt wheel and the lower synchronous belt wheel are both fixedly connected to the rotating shaft of the electromagnetic heating roller.

[0007] Further, the upper driving wheel is arranged below the upper synchronous belt wheel. One upper driving wheel is simultaneously connected to multiple upper synchronous belt wheels. The upper driving wheel is connected to the output shaft of a speed reducer one. The output shaft of the speed reducer one outside the upper driving wheel is coaxially connected to the helical gear one through a main belt wheel bushing. The input shaft of the speed reducer one is connected to the output shaft of the motor one.

[0008] Further, the lower driving wheel is arranged above the lower synchronous belt wheel. One lower driving wheel is simultaneously connected to multiple lower synchronous belt wheels.

[0009] Further, the main belt wheel bushing is coaxially connected to the helical gear one. The helical gear one meshes with the helical gear two. The output shaft of the helical gear two is connected to the lower driving wheel. The helical gear one and the helical gear two are arranged in a gear box. Synchronous rotation is achieved between the upper synchronous belt wheel and the upper driving wheel through the upper synchronous belt, and synchronous rotation is achieved between the lower synchronous belt wheel and the lower driving wheel through the lower synchronous belt.

[0010] Further, tension wheels are provided between the upper driving wheel and the upper synchronous belt wheel, and between the lower driving wheel and the lower synchronous belt wheel.

[0011] Further, the power component two includes a motor two, a speed reducer two, and a rotating shaft connecting body. One end of the rotating shaft connecting body is connected to the rotating shaft of the over-roller, and the other end is connected to the output shaft of the speed reducer two. The input shaft of the speed reducer two is connected to the motor two.

[0012] Furthermore, the leveling support includes a support plate, a fixed rod and an adjusting rod arranged on the support plate, and an adjusting screw nut fixed on the support plate. The support plate is used to fix the first reducer and the second reducer. The fixed rod and the adjusting rod are both arranged on the side of the support plate facing the equipment vertical plate. The ends of the fixed rod and the adjusting rod away from the support plate form positioning rods inserted into the through holes on the equipment vertical plate. The fixed rod is fixedly connected to the equipment vertical plate. The central axis of the adjusting screw nut is perpendicular to the support plate. One end of the adjusting rod close to the support plate forms a threaded column. The central axis of the threaded column coincides with the central axis of the adjusting rod. The threaded column is threadedly connected to the adjusting screw nut.

The first power assembly and the second power assembly are independently arranged, replacing the traditional chain drive and reducing the risk of belt breakage; by setting the first helical gear and the second helical gear to mesh to achieve forward and reverse rotation, the rotation directions of the upper driving wheel and the lower driving wheel are opposite, so that the rotation directions of the upper synchronous belt wheel and the lower synchronous belt wheel are opposite, and the rotation directions of the electromagnetic heating rollers connected to the upper synchronous belt wheel and the lower synchronous belt wheel are opposite. The pole coil is staggered between the upper synchronous belt wheel and the lower synchronous belt wheel, that is, after passing through an upper synchronous belt wheel, it is transmitted to a lower synchronous belt wheel, and then transmitted to an upper synchronous belt wheel, and is transmitted in turn, increasing the pole coil travel and improving the dehumidification efficiency; by setting the leveling support, the output shaft of the first reducer is coaxially aligned with the input shaft of the speed changer, and the output shaft of the second reducer is coaxially aligned with the rotating shaft connector, realizing smooth transmission.

[0036] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0037] Such as Figures 1-12As shown in the figure, a main over-roller independent servo drive mechanism is used to control the rotation of the over-roller 1 and the electromagnetic heating roller 2. The over-roller 1 and the electromagnetic heating roller 2 are horizontally mounted between two parallel equipment vertical plates 3. Multiple groups of main over-roller independent servo drive mechanisms are distributed in the length direction of the equipment vertical plates 3. The main over-roller independent servo drive mechanism includes a power component one 4 for providing power to the electromagnetic heating roller 2 and a power component two 5 for providing power to the over-roller 1. The power component one 4 and the power component two 5 are independently arranged. The pole coil 6 enters from the over-roller 1 and is then transmitted to the electromagnetic heating roller 2 for heating. Leveling brackets 7 are connected to both the power component two 5 and the power component one 4. The power component one 4 includes multiple upper synchronous belt wheels 401 distributed on the upper part of the equipment vertical plate 3, an upper driving wheel 403 connected to the upper synchronous belt wheel 401 through an upper synchronous belt 402, a motor one 407 connected to the upper driving wheel 403, lower synchronous belt wheels 404 distributed on the lower part of the equipment vertical plate 3, and a lower driving wheel 406 connected to the lower synchronous belt wheel 404 through a lower synchronous belt 405. The upper driving wheel 403 is coaxially connected to a helical gear one 11, and the lower driving wheel 406 is coaxially connected to a helical gear two 12. The helical gear one 11 meshes with the helical gear two 12. Under the action of the helical gear one 11 and the helical gear two 12, the rotation directions of the upper synchronous belt wheel 401 and the lower synchronous belt wheel 404 are opposite.

[0038] As Figure 1 shown, in one embodiment, each upper synchronous belt wheel 401 is connected to an electromagnetic heating roller 2 arranged on the upper part of the equipment vertical plate 3, each lower synchronous belt wheel 404 is connected to an electromagnetic heating roller 2 arranged on the lower part of the equipment vertical plate 3. Both the upper synchronous belt wheel 401 and the lower synchronous belt wheel 404 are fixedly connected to the rotating shaft of the electromagnetic heating roller 2. The upper synchronous belt wheel 401 and the lower synchronous belt wheel 404 are used to drive the rotation of the electromagnetic heating roller 2.

[0039] As Figure 2 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 1 1, Figure 12 shown, in one embodiment, the upper driving wheel 403 is arranged below the upper synchronous belt wheel 401. For example, one upper driving wheel 403 is simultaneously connected to two upper synchronous belt wheels 401. One upper driving wheel 403 and two upper synchronous belt wheels 401 are distributed in an inverted triangle. The upper driving wheel 403 is connected to the output shaft 10 of the first reducer. The upper driving wheel 403 and the output shaft 10 of the first reducer are connected through a keyway, for example. The output shaft 10 of the first reducer outside the upper driving wheel 403 is coaxially connected to the helical gear one 11 through a main pulley shaft sleeve 8. The input shaft of the first reducer 9 is connected to the output shaft of the motor one 407.

[0040] AsFigure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown in Figure 8 , in one embodiment, the lower driving pulley 406 is disposed above the lower synchronous pulley 404. For example, one lower driving pulley 406 is simultaneously connected to two lower synchronous pulleys 404, and one lower driving pulley 406 and two lower synchronous pulleys 404 are distributed in an upright triangle.

[0041] Such as Figure 3 , Figure 6 , Figure 9 As shown in Figure 9 , in one embodiment, the main pulley bushing 8 is coaxially connected to the first helical gear 11. The first helical gear 11 meshes with the second helical gear 12. The output shaft of the second helical gear 12 is connected to the lower driving pulley 406. The first helical gear 11 and the second helical gear 12 are disposed in the gearbox 13. Forward and reverse rotations are achieved through the meshing of the first helical gear 11 and the second helical gear 12, such that the rotation directions of the upper driving pulley 403 and the lower driving pulley 406 are opposite. Synchronous rotation is achieved between the upper synchronous pulley 401 and the upper driving pulley 403 via the upper synchronous belt 402, and synchronous rotation is achieved between the lower synchronous pulley 404 and the lower driving pulley 406 via the lower synchronous belt 405. Therefore, the rotation directions of the upper synchronous pulley 401 and the lower synchronous pulley 404 are opposite, and the rotation directions of the electromagnetic heating roller 2 connected to the upper synchronous pulley 401 and the lower synchronous pulley 404 are opposite. The pole roll 6 is staggered between the upper synchronous pulley 401 and the lower synchronous pulley 404, that is, after passing through one upper synchronous pulley 401, it is transmitted to one lower synchronous pulley 404, and then transmitted to one upper synchronous pulley 401, and is transmitted in sequence, increasing the stroke of the pole roll 6 and improving the dehumidification efficiency.

[0042] Such as Figure 8 As shown in Figure 8 , in one embodiment, tension pulleys 14 are provided between the upper driving pulley 403 and the upper synchronous pulley 401, and between the lower driving pulley 406 and the lower synchronous pulley 404, for adjusting the tension of the upper synchronous belt and the lower asynchronous belt.

[0043] Such as Figure 8 , Figure 9 As shown in Figure 9 , in one embodiment, the second power assembly 5 includes a second motor 501, a second speed reducer 502, and a rotating shaft connecting body 503. One end of the rotating shaft connecting body 503 is connected to the rotating shaft of the passing roller 1, and the other end is connected to the output shaft of the second speed reducer 502. The input shaft of the second speed reducer 502 is connected to the second motor 501. The rotating shaft connecting body 503 is formed by connecting two T-shaped connectors back to back, and the two connectors are connected by bolts. Grooves 504 are formed on the connectors. The rotating shaft of the passing roller 1 is connected to one of the grooves 504, and the output shaft of the speed reducer is connected to the other groove 504.

[0044] As Figure 4 shown, in one embodiment, the leveling bracket 7 includes a support plate 701, a fixed rod 702 and an adjusting rod 703 disposed on the support plate 701, and an adjusting screw nut 704 fixed to the support plate 701. The support plate 701 is used to fix the first reducer 9 and the second reducer 502. The fixed rod 702 and the adjusting rod 703 are both disposed on the side of the support plate 701 facing the equipment vertical plate 3. For example, there is one fixed rod 702 and three adjusting rods 703. The fixed rod 702 and the adjusting rods 703 are disposed at the four corners of the support plate 701. A positioning rod 705 for inserting into the through hole on the equipment vertical plate 3 is formed at one end of the fixed rod 702 and the adjusting rods 703 away from the support plate 701. The diameter of the positioning rod 705 is smaller than that of the fixed rod 702 and the adjusting rods 703. The fixed rod 702 is fixedly connected to the equipment vertical plate 3. The central axis of the adjusting screw nut 704 is perpendicular to the support plate 701. A threaded column is formed at one end of the adjusting rod 703 close to the support plate 701. The central axis of the threaded column coincides with the central axis of the adjusting rod 703. The threaded column is threadedly connected to the adjusting screw nut 704. By rotating the adjusting rod 703, the length of the threaded column entering the adjusting screw nut 704 is adjusted to finely adjust the distance between the support plate 701 and the equipment vertical plate 3. The leveling bracket 7 disposed on the first power assembly 4 is used to adjust the output shaft 10 of the first reducer to be coaxial with the main pulley shaft sleeve 8. The leveling bracket 7 disposed on the second power assembly 5 is used to adjust the output shaft of the second reducer 502 to be coaxial with the rotating shaft connecting body 503, so as to achieve smooth transmission.

[0045] As Figure 1 shown, in one embodiment, the over-roller 1 is disposed in the entering and output directions of the pole coil 6 of the electromagnetic heating roller 2.

[0046] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
