Description

Technical Field

[0001] The utility model relates to the technical field of metal foil manufacturing, in particular to a belt-type material transmission device. Background Art

[0002] In the production, preparation and surface treatment of rolled foil, in order to achieve continuous production and improve the efficiency of production and processing, belt transmission equipment is often required, especially in the production of metal foils such as copper foil or aluminum foil.

[0003] Belt transmission equipment is mainly composed of active rollers and passive rollers. During the movement of belt transmission equipment, it is often necessary to perform tension detection on the belt material (such as metal foil such as copper foil or aluminum foil). In order not to affect the test results and not to introduce external force into the passive roller for direct transmission, the passive roller mainly rotates by the friction between the passive roller and the belt material. However, this operation mode can easily cause slippage between the passive roller and the belt material, which will cause some defects such as small scratches on the surface of the belt material, affecting the production quality of the belt material. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defect of the belt transmission equipment in the prior art that slippage easily occurs between the passive roller and the belt material during operation, which affects the production quality of the belt material, thereby providing a belt material transmission device.

[0031] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0033] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0035] like Figure 1 and Figure 2 The figure shows a belt material transmission device provided by the present embodiment, comprising a first roller 1 and a first transmission assembly 4, wherein the first roller 1 is driven to rotate by a driving mechanism; a passive roller 2 is arranged on one side of the first roller 1 along the transmission direction of the belt material 3, wherein the first roller 1 and the passive roller 2 are used for placing the belt material 3 and driving the belt material 3 to be transported along the transmission direction; a rotating shaft 41 is axially penetrated through the first transmission assembly 4, wherein one end of the rotating shaft 41 along the axial direction is connected to the first roller 1 through a first belt 11, and rotates synchronously with the first roller 1; the other end of the rotating shaft 41 along the axial direction is coaxially softly connected to the passive roller 2 through a connecting member 5, wherein the connecting member 5 has a first state in which the passive roller 2 and the rotating shaft 41 are separated, and a second state in which the passive roller 2 and the rotating shaft 41 are connected as a whole. It can be understood that the axial direction described in the present embodiment refers to Figure 1 Axial direction in.

[0036] The belt material transmission device of this embodiment makes the rotating shaft 41 and the first roller 1 rotate synchronously through the first belt 11, and the end of the rotating shaft 41 facing the passive roller 2 is coaxially softly connected with the passive roller 2 through the connecting member 5. When the friction between the belt material 3 and the passive roller 2 is maintained so that the rotation speed of the passive roller 2 is basically consistent with the rotation speed of the first roller 1, the connecting member 5 is maintained in the first state, that is, the rotating shaft 41 and the passive roller 2 are not associated with each other; when the friction between the belt material 3 and the passive roller 2 is reduced to a level where no slipping occurs, the speed difference between the passive roller 2 and the first roller 1 causes the connecting member 5 to switch from the first state to the second state, that is, the rotating shaft 41 is associated with the passive roller 2, and the rotating shaft 41 drives the passive roller 2 to rotate synchronously, so that even if the friction between the belt material 3 and the passive roller 2 is reduced, there will be no relative displacement between the belt material 3 and the passive roller, that is, no slipping will occur, thereby avoiding scratches or lines on the surface of the belt material 3 and ensuring the production quality of the belt material 3.

[0037] It can be understood that the output end of the belt material transmission device of this embodiment is also equipped with multiple rollers connected in sequence along the transmission direction of the belt material 3, so that the belt material 3 is transmitted by the belt material transmission device of this embodiment and then transmitted between multiple rollers until it is rolled up.

[0038] It is understandable that when the friction between the belt material 3 and the passive roller 2 is not reduced to make the connecting member 5 switch from the first state to the second state, that is, when the rotating shaft 41 and the passive roller 2 are not associated with each other, the tension detection result is not affected.

[0039] It should be noted that the transmission device of this embodiment can be used in the post-processing process and the foil production process of copper foil, and can also be used in the post-processing process and the foil production process of aluminum foil. The belt material 3 mentioned in the text refers to metal foil materials such as copper foil or aluminum foil.

[0040] In some embodiments of the utility model, the connecting member 5 is configured as a soft rubber sleeve, and the soft rubber sleeve is respectively provided with a first hole and a second hole at both ends along the axial direction, the end of the rotating shaft 41 facing the soft rubber sleeve is connected to the first hole, and the end of the passive roller 2 facing the soft rubber sleeve is connected to the second hole. The soft rubber sleeve has a certain amount of deformation, and the soft rubber sleeve will be deformed when there is a speed difference between the rotating shaft 41 and the passive roller 2, that is, the friction between the belt material 3 and the passive roller 2 gradually decreases to a process where slipping does not occur. The speed difference between the rotating shaft 41 and the passive roller 2 will cause the soft rubber sleeve to gradually produce torsional deformation. When the deformation of the soft rubber sleeve reaches the upper limit value, it can no longer deform. At this time, the soft rubber sleeve switches to the second state, that is, the rotating shaft 41 is associated with the passive roller 2, so that the rotating shaft 41 drives the passive roller 2 to rotate together, ensuring that even if the friction between the belt material 3 and the passive roller 2 is reduced, there will be no relative displacement between the belt material 3 and the passive roller 2, that is, no slipping will occur, thereby avoiding scratches or lines on the surface of the belt material 3 and other defects, thereby ensuring the production quality of the belt material 3.

[0041] like Figure 2 As shown, in some embodiments of the utility model, the first transmission assembly 4 includes a mounting plate 42, the mounting plate 42 is used to connect to the channel steel of the production line, the upper end of the mounting plate 42 is provided with a base 43, the base 43 is formed with a through hole along the axial direction, the rotating shaft 41 passes through the through hole and is rotatably connected in the through hole. Through the transition connection between the mounting plate 42 and the base 43, the rotating shaft 41 can be smoothly rotated relative to the production line, so that the rotating shaft 41 can not only rotate smoothly and synchronously with the first roller 1, but also drive the passive roller 2 to rotate together when the connecting member 5 is in the second state, effectively avoiding the slippage between the passive roller 2 and the belt material 3, and ensuring the production quality of the belt material 3.

[0042] like Figure 2 As shown, in some embodiments of the utility model, a bearing 44 is respectively disposed at both ends of the through hole along the axial direction, and the rotating shaft 41 is rotatably connected in the bearing 44. The two bearings 44 disposed at intervals along the axial direction increase the rotation contact area with the rotating shaft 41, and further improve the rotation stability of the rotating shaft 41.

[0043] like Figure 2As shown, in some embodiments of the utility model, the upper end of the mounting plate 42 is provided with an internal threaded hole 421, and the base 43 is provided with a through hole 431 corresponding to the internal threaded hole 421. When the mounting plate 42 and the base 43 are assembled, it is only necessary to pass the fastening bolt through the through hole 431 and screw it into the corresponding internal threaded hole 421. Compared with the assembly by welding, the assembly method of the base 43 and the mounting plate 42 in this embodiment is convenient for assembly operation and for removing the base 43 for replacement or repair. In order to improve the stability of the base 43 connected to the mounting plate 42, specifically, one of the internal threaded holes 421 is provided at the four corners of the upper end of the mounting plate 42, and one of the through holes 431 is provided at the positions corresponding to the four internal threaded holes 421 on the base 43.

[0044] In order to facilitate fine-tuning of the position of the base 43 relative to the mounting plate 42, it is ensured that the base 43 and the mounting plate 42 are precisely connected to each other on the basis of the coaxial soft connection between the rotating shaft 41 and the passive roller 2 through the connecting member 5; Figure 2 As shown, in some embodiments of the present invention, the through hole 431 is configured as a waist-shaped hole.

[0045] like Figure 1 As shown, in some embodiments of the utility model, the driving mechanism includes a motor 61, and the output end of the motor 61 is connected to the first roller 1 through a second transmission component. Through the effect of transmitting torque through the second transmission component, the torque output by the output end of the motor 61 is transmitted to the first roller 1, thereby driving the first roller 1 to rotate and transmitting the belt material 3.

[0046] In some embodiments of the utility model, the second transmission assembly includes a second belt 62, and the second belt 62 is wound between the output end of the motor 61 and the first roller 1. Through the transmission action of the second belt 62, the first roller 1 rotates together with the output end of the motor 61, thereby realizing the function of transmitting the belt material 3.

[0047] The second transmission assembly of this embodiment is not limited to the above structure. As another alternative to the above technical solution, the second transmission assembly includes a first gear and a second gear meshing with each other, the first gear has more teeth than the second gear, the first gear is coaxially arranged on the first roller 1, and the second gear is coaxially arranged on the output end of the motor 61. Because the transmission ratio of the first gear and the second gear is greater than 1, the speed of the output end of the motor 61 is greater than the speed of the first roller 1, so that the torque transmitted to the first roller 1 becomes larger, thereby driving the belt material 3 to be transmitted more smoothly. Specifically, the second transmission assembly and the motor 61 are arranged to form a gear reduction motor in one piece.

[0048] like Figure 1 As shown, in some embodiments of the utility model, the driving mechanism and the first transmission assembly 4 are located on the same side of the first roller 1 along the axial direction, which makes the spatial layout more reasonable, reduces the occupation of the axial space of the factory, and better utilizes the factory space.

[0049] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
