[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention employs electromagnetic roller heating, a method that rapidly converts electrical energy into heat energy to directly heat the electrode roll, significantly increasing the heating rate. Precise temperature control of the electromagnetic roller ensures the uniformity and controllability of the drying process, effectively preventing localized overheating or incomplete drying, thus improving the quality and consistency of the dried product. It also solves the problem of insufficient or uneven baking time in traditional drying equipment, thereby improving drying efficiency and product quality. By installing at least one set of electromagnetic roller heating and baking components within the baking chamber, the travel distance of the electrode roll within the baking chamber is effectively extended, increasing the contact area between the electrode roll and the heating roller. Both the drying time and the drying process have been increased, ensuring more thorough and uniform heat transfer. This allows each section of the roller to reach the desired dryness after receiving sufficient heat treatment, greatly improving the thoroughness and consistency of drying. As the roller travels further within the baking chamber, heat utilization is maximized. The electromagnetic roller heating method itself features rapid response and efficient conversion. At the same time, the hot air circulation and recovery technology, combined with the increased roller travel, achieves more efficient moisture removal, ensuring that heat is fully utilized in every area through which the roller passes, reducing heat loss and improving overall drying efficiency.

[0046] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention.

[0047] In this invention, by introducing electromagnetic roller heating technology, the entire set of equipment is optimized and upgraded, specifically reflected in the following components and functions:

[0048] Electrode roll unwinding mechanism: This mechanism is responsible for evenly releasing the electrode roll material to be baked from the roll and sending it into the baking chamber. The application of electromagnetic roller heating technology enables the electrode roll to quickly obtain the required preheating temperature during the unwinding process, preparing it for subsequent efficient baking.

[0049] Electromagnetic heating roller transmission system: This system is the core part of the invention. It consists of an electromagnetic roller, a servo motor, a reducer, a synchronous belt, etc. The electromagnetic roller, as a heating element, can quickly generate heat through its non-contact electromagnetic induction mechanism, so as to achieve uniform and efficient heating of the passing polar roll. The servo motor and the reducer work together to ensure that the electromagnetic roller rotates at a constant speed, thereby ensuring the consistency of the baking effect.

[0050] Hot air circulation system: It assists in heating the electromagnetic rollers and further enhances the heat transfer efficiency in the baking chamber through hot air circulation. The hot air can be evenly distributed in the baking chamber, making the heating of each part of the roller more uniform. It also helps to remove the moisture generated during the baking process and improve the drying efficiency.

[0051] Electrode roll cooling mechanism: After baking, the electrode roll needs to be cooled down quickly by the cooling mechanism in order to solidify the baking effect and carry out subsequent processing. The electromagnetic roller heating method heats up quickly and cools down relatively quickly, which helps to improve the operating efficiency of the entire production line.

[0052] Electrode roll slitting and rewinding mechanism: The baked and cooled electrode rolls are conveyed to the slitting and rewinding mechanism, where they are cut and rewound according to requirements. The electromagnetic roller heating ensures the consistency and quality of the electrode rolls, making the slitting and rewinding process smoother and ultimately producing high-quality products.

[0053] The entire equipment is centered around a baking chamber. Through the application of electromagnetic roller heating technology, it realizes a series of efficient and automated production processes from unwinding, high-efficiency baking, cooling to slitting and rewinding of the battery rolls. Electromagnetic roller heating not only improves drying efficiency and product quality, but also greatly enhances the equipment's operational stability and production adaptability due to its rapid response and precise temperature control characteristics. This invention achieves more efficient moisture removal by optimizing the layout of the electromagnetic rollers and the design of the transmission system, while reducing the need for subsequent battery cell baking equipment, thereby improving overall production efficiency and product quality.

The upper hull 2 ​​is located at the top of the baking chamber 1, and the lower hull 3 is located at the bottom of the baking chamber 1. The hot air heating device 4 includes a circulating heating assembly 41. The outlet of the circulating heating assembly 41 introduces hot air into the upper hull 2 ​​and the lower hull 3 through a diversion tee 42. The return air outlet of the circulating heating assembly 41 connects the upper hull 2 ​​and the outside air, and the hot air heating device 4 forms a hot air circulation with the upper hull 2 ​​and the lower hull 3. The hot air recovery device 5 includes a hot air recovery machine 51. The inlet of the hot air recovery machine 51 is connected to the inlet and outlet of the baking chamber 1 through a suction pipe 52, and the outlet of the hot air recovery machine 51 is connected to the return air outlet of the circulating heating assembly 41. The baking chamber 1 is used to provide the baking stroke space for the electromagnetic roller 151 to be heated in contact.

[0055] In one embodiment, a protective plate 6 is provided on the outside of the device of the present invention, which can protect the entire device.

[0056] In one embodiment, the hot air heating device 4 is equipped with multiple heating packs in the heating unit, which are precisely controlled by solid-state relays and equipped with temperature sensors for real-time monitoring. This ensures that the temperature can be flexibly adjusted within the range of 25°C to 200°C to meet the diverse temperature requirements of different production processes. The air outlet of the air-cooled heating component 41 guides hot air into the upper hull 2 ​​and lower hull 3 through a diversion tee to form thermal convection, which improves drying efficiency and ensures the uniformity of the heating process. The return air outlet of the air-cooled heating component 41 returns air from the upper hull 2 ​​and replenishes fresh air from the external environment through a filter, realizing the recycling and replenishment of air. The dehumidification component 46 forms a dehumidification stroke through the air inlet and outlet of the dehumidification fan 461. The dehumidification fan 461 adopts an explosion-proof variable frequency fan to provide power to the dehumidification component 46, ensuring that moisture can be effectively discharged.

[0057] In one embodiment, the two ends of the hose 43 have different shapes, with the upper end being circular and the lower end being rectangular. The air supply heating assembly 41 and the return air outlet are connected by the hose 43. The fan vibration damping bracket 45 at the bottom of the heating fan 44 is used to avoid resonance caused by rigid connection, thereby achieving the purpose of vibration reduction and noise reduction.

[0058] In one embodiment, the hot air recovery machine 51 draws in the hot air and creates a negative pressure in the hot air recovery pipeline. The suction pipe 52 draws in the hot air overflowing from the electrode inlet 131 and electrode outlet 141 of the baking chamber 1. The drawn-in hot air is discharged through the outlet of the hot air recovery machine 51 to the return air port of the air heating component 41, thus completing the hot air recovery process.

[0059] like Figure 3 As shown, the present invention provides an uncoiling and baking device using electromagnetic roller heating. The main body of the baking chamber 1 is formed by a first vertical plate 11, a second vertical plate 12, an electrode inlet plate 13, and an electrode outlet plate 14, forming a baking space inside.

[0060] In one embodiment, the first vertical plate 11 and the second vertical plate 12 are arranged opposite to each other, and the electrode roll inlet plate 13 and the electrode roll outlet plate 14 are arranged opposite to each other. The electrode roll inlet plate 13 is provided with an electrode roll inlet 131, and the electrode roll outlet plate 14 is provided with an electrode roll outlet 141. In the baking space between the electrode roll inlet 131 and the electrode roll outlet 141, a baking stroke for extending the electrode roll in the baking cavity 1 is provided, optimizing the layout of the electromagnetic roller 151, and achieving more efficient moisture removal.

[0061] like Figures 4 to 6 In one embodiment shown, three sets of electromagnetic roller heating and baking assemblies 15 are arranged between the first vertical plate 11 and the second vertical plate 12. Electromagnetic rollers 151 are rotatably connected to the first vertical plate 11 and the second vertical plate 12 via bearing components. Overhead rollers 157 are rotatably connected to the first vertical plate 11 and the second vertical plate 12 via bearing components. Figure 5On the first upright plate side, the electromagnetic rollers 151 in each set of electromagnetic roller heating and baking assemblies 15 are respectively arranged on the upper and lower sides of the servo motor 152, with two electromagnetic rollers 151 arranged side by side on the upper side of the servo motor 152 and two electromagnetic rollers 151 arranged side by side on the lower side of the servo motor 152. The electromagnetic rollers 151 on the upper side of the servo motor 152 are connected to the gearbox 156 through a synchronous belt 154, and the electromagnetic rollers 151 on the lower side of the servo motor 152 are connected to the gearbox 156 through a synchronous belt 154. The two synchronous belts 154 are connected to the gearbox 156. 54 is connected to two meshing helical gears of gearbox 156 respectively, realizing the reverse rotation of the upper and lower electromagnetic rollers 151. At the same time, each electromagnetic roller heating and baking assembly 15 is provided with two sets of guide rollers 157. The guide rollers 157 are rotated and engaged by guide roller motor 158. The two guide rollers 157 are respectively located on both sides of the electromagnetic roller 151. According to the actual operation, the electromagnetic roller heating and baking assembly 15 located on the pole roll inlet 131 side of the baking chamber 1 has a guide roller arranged parallel to the left side of the lower electromagnetic roller 151. 157, a guide roller 157 is arranged parallel to the right side of the upper electromagnetic roller 151, and a threading mechanism 155 is arranged below the left guide roller 157 to provide the driving force for the pole roll to pass through the pole roll inlet 131 to the pole roll outlet 141; the magnetic roller heating and baking assembly 15 located in the middle part of the baking chamber 1 has a guide roller 157 arranged parallel to the left side of the upper electromagnetic roller 15 and a guide roller 157 arranged parallel to the right side of the upper electromagnetic roller 151. The left guide roller 157 in this part is used to support... The electrode roll passing through the left electromagnetic roller heating and baking assembly 15 helps to smoothly guide the electrode roll into the electromagnetic roller 151; the electromagnetic roller heating and baking assembly 15 located on the electrode roll outlet 141 side of the baking chamber 1 has a guide roller 157 arranged parallel to the left side of the upper electromagnetic roller 151 and a guide roller 157 arranged parallel to the right side of the lower electromagnetic roller 151. The left guide roller 157 is used to receive the electrode roll passing through the left electromagnetic roller heating and baking assembly 15, and the right guide roller 157 is used to exit the electrode roll; in summary, it forms as follows Figure 4 The direction of the electrode roll shown extends the baking stroke of the electrode roll within the baking chamber 1, achieving more efficient moisture removal.

[0062] like Figure 5 and Figure 9 In one embodiment shown, the electromagnetic roller 151 is connected to the second vertical plate 12 via a bearing component. The outer side of the bearing component is connected to the synchronous belt 154 via a synchronous pulley 1511. The outer side of the synchronous pulley 1511 is connected to an inner slip ring 1512 for adjusting the tension of the synchronous belt 1511. An inner roller fixing end sleeve 1513 is provided on the outer side of the inner slip ring 1512. The inner roller fixing end sleeve 1513 is fixed by an inner roller fixing block 1514 and a fixing rod 1515 for securing the end shaft of the electromagnetic roller 151 protruding from the second vertical plate 12 and stably fixing it on the second vertical plate 12.

[0063] like Figure 11As shown, in one embodiment, the bearing component between the electromagnetic roller 151 and the first vertical plate 11 and the second vertical plate 12 is connected to a coolant delivery pipe 1516, through which coolant is introduced to cool the bearing; and a lubricating oil cavity is provided between the multiple bearing components connected to the end shaft of the electromagnetic roller 151, through which high-temperature resistant grease is introduced to lubricate the bearing components.

[0064] More specifically, annular cooling grooves are installed on the bearings, connected to a coolant delivery pipe 1516. Coolant enters the annular cooling grooves through the coolant inlet and exits through the coolant inlet and outlet. After flowing through multiple annular cooling grooves, the coolant returns to the coolant delivery pipe 1516, which is connected to a refrigeration device. This cycle repeats continuously, forming a heat circulation that carries away heat from the bearings and lowers their operating temperature. Furthermore, lubricating oil chambers are installed within multiple bearing housings. Grease enters these chambers, providing lubrication while absorbing heat transferred to the rollers, further reducing bearing temperature and improving durability. The simultaneous circulation of high-temperature resistant grease and coolant cools the bearings, enhancing cooling efficiency, extending bearing life, reducing bearing replacement frequency, and lowering economic costs.

[0065] like Figure 6 and Figure 8In one embodiment shown, a tensioning pulley device 159 is provided on the outer side of the synchronous belt 154. The tensioning pulley device 159 is used to maintain appropriate tension on the synchronous belt 154. The tensioning pulley device 159 includes an adjusting base 1591, an adjusting block 1592, an adjusting screw 1593, and an adjusting nut 1594. The adjusting base 1591 is provided with a sliding groove 15911 adapted to the adjusting block 1592. The adjusting block 1592 is fixedly connected to the tensioning pulley 15921, which is located on the outer side of the synchronous belt 154. The adjusting block 1592 is provided with a threaded seat 15922 adapted to the adjusting screw 1593. The adjusting screw 1593 is rotatably connected to the ear plate hole 15912 of the adjusting base 1591. The top end of the adjusting screw 1593 is connected to the adjusting nut 1594. Initially, the synchronous belt 154 is in a slack state and needs to be adjusted by… The tensioning wheel device 159 is used to adjust the tension. The adjusting base 1591 is provided with a sliding groove 15911 to accommodate the sliding of the adjusting block 1592. The adjusting block 1592 is fixedly connected to the tensioning wheel 15921. When the adjusting screw 1593 is rotated by the adjusting nut 1594, the threaded seat 15922, which is rotatably connected to the adjusting screw 1593, will convert the rotation of the adjusting screw 1593 into linear motion of the adjusting block 1592, pushing the adjusting block 1592 to move along the sliding groove 15911. This causes the tensioning wheel 15921 to apply appropriate tension to the synchronous belt 154. By repeatedly rotating the adjusting screw 1593 and observing the position change of the tensioning wheel 15921, the tension of the synchronous belt 154 can be precisely adjusted to the ideal state. The synchronous belt 154 will run under appropriate tension, ensuring the smooth operation and long-term stability of the mechanical equipment.

[0066] like Figure 5 As shown, in one embodiment of the present invention, the first vertical plate 11 has a reserved vertical plate roller replacement hole 7 and an inspection door 8, which facilitates the replacement of the electromagnetic roller 151 and the through roller 157. Operators can easily remove the old roller and install the new roller without disassembling the entire equipment, saving time, reducing labor intensity, reducing downtime, and improving work efficiency.

[0067] like Figure 5 As shown, in one embodiment of the present invention, the end shaft of the electromagnetic roller 151 protruding from the outer side of the first vertical plate 11 is provided with a brake assembly 160. The brake assembly 160 ensures production safety, prevents accidental movement of the equipment, and controls emergencies; it also improves operational accuracy, ensures precise positioning, controls start and stop, and optimizes the production process; further enhancing equipment performance, reducing mechanical wear, and improving energy efficiency.
