Description

Technical Field

[0001] The invention relates to an electromagnetic brake device for an active heating roller, belonging to the technical field of battery manufacturing equipment. Background Art

[0002] With the rapid development of the new energy battery industry, the demand for the processing of foil materials has increased significantly. The foil contains a certain amount of moisture during the production process. If it is not dried in time, the moisture will cause oxidation and other problems, resulting in a decline in product quality. At present, electromagnetic roller heating technology has become the preferred method for high-precision and uniform heating. The electromagnetic roller uses the principle of electromagnetic induction to generate a strong magnetic field inside the roller, so that the metal foil is quickly heated and dried when passing through the electromagnetic roller. Compared with traditional electric heating or infrared heating methods, electromagnetic roller heating has higher temperature control accuracy and less effect on the physical properties of the foil, which is suitable for the high-demand environment of new energy battery production.

[0003] However, the structural design of the electromagnetic roller results in its heavy weight, which generates a large rotational inertia during operation. When an emergency occurs (such as material jamming, equipment failure or safety hazard), the rotation of the electromagnetic roller needs to be stopped quickly to avoid accidents. However, traditional mechanical brakes have obvious shortcomings when facing the high inertia load of the electromagnetic roller, and usually cannot complete effective braking in a short time. This slow braking may cause damage to the equipment or even cause safety accidents. In addition, mechanical brake devices are susceptible to wear, have a short service life, and require high maintenance frequency, which is not conducive to the efficiency and continuity of industrial production.

[0004] In response to the above problems, electromagnetic brake technology has gradually attracted the attention of the industry. Electromagnetic brakes use electromagnetic force to control the motion state of rotating parts. Compared with mechanical brake systems, they have advantages such as fast response speed and high precision. They are suitable for high-inertia and high-precision rotating equipment. The heated electromagnetic roller is prone to electromagnetic brake misfires due to thermal expansion.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of this application.

[0026] like Figure 1 , 2 , 3 show the overall structure and usage status of the active heating roller electromagnetic brake device.

[0027] The present application provides an electromagnetic brake device for an active heating roller 1 , comprising an electromagnetic brake component 5 , a bearing assembly and a plum blossom coupling 6 .

The bearing 3 includes a bearing seat 3-1, and the bearing seat 3-1 is fixed to the vertical plate 2-1 by bolts. A double bearing 3-2 structure is arranged in the bearing seat 3-1, and the end shaft 1-1 passes through the double bearing 3-2 structure and is connected to the power end; The double bearing 3-2 structure provides stable rotation support.

[0031] The other end shaft 1 - 1 protrudes out of the second vertical plate 2 - 2 , is inserted into the second bearing 4 provided on the second vertical plate 2 - 2 , and is connected with the plum blossom coupling 6 .

[0032] The bearing 2-4 is a seat bearing, which is fixed on the vertical plate 2-2 by bolts.

[0033] A fixed key 5-32 or a keyway 6-16 is provided on the end shaft 1-1.

[0034] A bracket 2-3 is also provided on the second vertical plate 2-2, and the bracket 2-3 is connected with an electromagnetic brake component 5 and a bearing assembly.

[0035] The bracket 2-3 is zigzag-shaped, including a first end, a second end, and a middle end, wherein the first end and the second end are located at two ends of the middle end; The first end of the bracket 2-3 is connected to the vertical plate 2-2, and the second end of the bracket 2-3 is connected to the electromagnetic brake component 5; The middle end of the bracket 2-3 is connected with a bearing assembly, and the bearing assembly includes a bearing three 5-8 and a fixing seat 5-9; Bearing three 5-8 is arranged in the fixing seat 5-9, and the fixing seat 5-9 is fixedly connected to the middle end of the bracket 2-3.

[0036] The central axes of bearing one 3, bearing two 4 and bearing three 5-8 are collinear.

[0037] like Figure 1 , 2, 3, 4, 5, 13, and 14 show the overall structure of the electromagnetic brake component and the installation position and connection relationship in the active heating roller electromagnetic brake device.

[0038] The electromagnetic brake component 5 includes a flange 5-1, a rotating disk 5-2, a brake shaft 5-3, a magnetic disk 5-4 and a pressure plate 5-5; The flange 5-1 is connected to the first end of the bracket 2-3. A coil 5-11 is arranged inside the flange 5-1. The coil 5-11 generates magnetic force when it is energized to attract the rotating disk 5-2. A connecting cavity is provided in the middle of the rotating disk 5-2 for connecting with the brake shaft 5-3. The rotating disk 5-2 is also provided with a fixing hole connected with the pressure plate 5-5.

[0039] The brake shaft 5-3 is located in the connecting cavity of the rotating disk 5-2; The pressure plate 5-5 is fixedly connected to the rotating disk 5-2 via the connecting bolts 5-6; the pressure plate 5-5 is fixedly connected to the brake shaft 5-3 via the fixing bolts 5-7; The pressure plate 5-5 is disc-shaped, and the through hole in the center is used to pass the fixing bolt 5-7 and fix it to the fixing screw hole set at one end of the brake shaft 5-3; The connecting holes on the edge of the pressure plate 5-5 are used to pass the connecting bolts 5-6 to fix it to the rotating disk 5-2.

[0040] A magnetic disk 5-4 is also provided on the rotating disk 5-2; the magnetic disk 5-4 is annular and is located on one side of the rotating disk 5-2, at the outer ring position.

[0041] When in use, the flange 5-1 is energized to attract the magnetic disk 5-4 to brake the rotating disk 5-2, and the brake shaft 5-3 connected to the rotating disk 5-2 is connected to the heating roller 1 through the coupling to brake the other end of the coupling.

[0042] The friction between the flange 5-1 and the magnetic disk 5-2 can provide braking force. In order to further protect the flange 5-1 from wear and tear and not affect the operation of the coil 5-11, a friction plate is provided on the flange, and the friction between the friction plate and the magnetic disk 5-2 provides braking force.

[0043] Since there is a brake gap 5-10 between the flange 5-1 and the magnetic disk 5-4, when the flange 5-1 is not powered, the heating roller 1 can rotate smoothly without hindrance.

[0044] When a friction plate is provided on the flange, there is a brake gap 5-10 between the friction plate and the magnetic disk 5-2. Fig.12 As shown, the structure of the brake shaft is shown.

[0045] The brake shaft 5-3 includes a shaft body 5-31, a fixing key 5-32 and a limiting ring 5-33; The shaft body 5-31 is cylindrical, and fixed keys 5-32 are set at both ends of the shaft body 5-31. A limit ring 5-33 is set between the two fixed keys 5-32. The limit ring 5-33 is connected to the bearing three 5-8 and is used to limit the bearing three 5-8 to prevent the electromagnetic brake component 5 from moving during rotation.

[0046] The plum blossom coupling 6 fixes the brake shaft 5-3 and the end shaft 1-1 of the heating roller 1 through the fixed key 5-32 of the brake shaft 5-3 so that they rotate synchronously.

[0047] like Figure 1 , 2 , 3, 6-11 show the overall structure of the plum blossom coupling, the structure and connection relationship of each component, and the use position and function of the active heating roller electromagnetic brake device.

[0048] The difference in expansion coefficient between the heating roller 1 and the chamber during the heating process will cause axial elongation, affecting the electromagnetic brake gap 5-10, resulting in electromagnetic brake misbraking or increased rotational resistance during operation. In order to solve this problem, a plum blossom coupling 6 is added between the electromagnetic brake and the shaft of the heating roller 1. The axial expansion difference of the heating roller 1 is absorbed by the plum blossom pad 6-2, and the electromagnetic brake gap 5-10 is always maintained.

[0049] The plum blossom coupling 6 comprises a fork shaft sleeve and a plum blossom washer 6-2, and the fork shaft sleeve comprises a fork shaft sleeve 1 6-1 and a fork shaft sleeve 2 6-3.

[0050] The shift fork shaft sleeve 6-1 is connected to the brake shaft 5-3 of the electromagnetic brake component 5. The shift fork shaft sleeve 2 6 - 3 is connected to the end shaft 1 - 1 of the heating roller 1 .

[0051] A plum blossom pad 6-2 is provided between the fork shaft sleeve 1 6-1 and the fork shaft sleeve 2 6-3. The plum blossom pad 6-2 can not only play a buffering role during transmission, but also absorb the expansion difference caused by the axial expansion of the heating roller 1, and always maintain the electromagnetic brake gap 5-10.

[0052] The main body of the plum blossom pad 6-2 is provided with a pad core 6-21, which is circular. Circular grooves 6-22 are provided on both sides of the middle of the pad core 6-21 for accommodating the transmission components of the electromagnetic brake component 5 and the stop component. The transmission components are the brake shaft 5-3 and the end shaft 1-1 of the stop component. The diameter of the groove 6-22 is larger than the diameter of the transmission component, that is, the diameter of the groove 6-22 is larger than the diameter of the end shaft 1-1 and the brake shaft 5-3.

[0053] Pad petals 6-23 are arranged around the pad core 6-21.

[0054] The plug-in sleeve is cylindrical in shape as a whole, and includes a cylindrical ring body 6-11, and a spline 6-12 is provided at one end of the ring body 6-11. The two shift fork shaft sleeves are arranged opposite to each other, and the splines 6-12 of the two shift fork shaft sleeves are arranged crosswise, and the gap between the splines 6-12 just accommodates the gasket 6-23.

[0055] The number and position of the splines 6-12 are matched with the number and position of the gaskets 6-23.

[0056] The ring body 6-11 is provided with an axial hole 6-15; A movable end 6-13 is provided at one end of the ring body 6-11 away from the spline 6-12, and the movable end 6-13 is located on the side of the ring body 6-11 away from the spline 6-12; The movable end 6-13 can be formed by partially cutting the end face of the ring body 6-11 and the side face of the ring body 6-11, so that a part of the ring body 6-11 forms the movable end 6-13 that can be opened and closed appropriately.

[0057] Fastening holes are provided on the movable end 6-13 and the ring body 6-11, and the fastening bolts 6-14 fasten the movable end 6-13 and the ring body 6-11 through the fastening holes.

[0058] A keyway 6-16 is provided on the movable end 6-13; the keyway 6-16 is used to accommodate the fixed key 5-32 or the movable key of the transmission shaft.

[0059] The movable key is a key that can be disengaged from the keyway 6-16 of the transmission shaft.

[0060] The fixed key 5-32 is a fixed key 5-32 on the transmission shaft.

[0061] The keyway 6-16 may penetrate the ring body 6-11, such as Figure 8 , 9 shown.

[0062] The keyway 6-16 may also not penetrate the ring body 6-11 but only penetrate the movable end 6-13, such as Fig.10 shown.

[0063] The keyway 6-16 cooperates with the fixed key 5-32 of the brake shaft 5-3 and the key of the end shaft 1-1, so that the plum blossom coupling 6 can stably connect the end shaft 1-1 and the brake shaft 5-3 to transmit power and braking force.

[0064] The setting of the movable end 6-13 can make it more convenient to connect and install the plug-in sleeve with the brake shaft 5-3 or the end shaft 1-1, and the cooperation is more stable.

[0065] In order to prevent the transmission shaft from slipping during transmission, keys are generally used to increase the stability of the transmission so that the power or braking force can fully act on the shaft. It is best if the key can fit exactly with the keyway, which is not easy to fall off and can maximize transmission.

[0066] However, this brings about the problems of high processing precision and inconvenient installation. With the design of movable end, the fastening bolts can be loosened during installation to obtain a larger installation space. The key and brake shaft or end shaft can be well locked by tightening the fastening bolts, while the requirements for processing precision are reduced.

[0067] The movable end 6-13 and the ring body 6-11 are connected as one piece and are not easy to be lost or fall off.

[0068] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
