[0027] The coiling and uncoiling device for diaphragm box production includes a material roll 3 and a coaxial reverse mechanism 4. The material roll 3 is connected with a rotating shaft 6. The coaxial reverse mechanism 4 is connected with a driving mechanism 2, and the output end of the coaxial reverse mechanism 4 is connected with the rotating shaft 6. Among them, the output end of the coaxial reverse mechanism 4 includes a sun gear 42 that rotates forward and a reverse wheel 45 that rotates in reverse. The reverse wheel 45 is provided with a reverse groove 46 penetrating along the axis, and the sun gear 42 and the reverse wheel 45 are coaxially arranged. A bushing 5 is sleeved on the rotating shaft 6. The rotating shaft 6 passes through the reverse groove 46 and is connected with the sun gear 42, and the bushing 5 is connected with the reverse wheel 45 through the reverse groove 46. There are two material rolls 3, one material roll 3 is connected with the rotating shaft 6, and the other material roll 3 is connected with the bushing 5. When the driving mechanism 2 is started, it drives the two material rolls 3 to rotate in reverse coaxially. So that the coiling and uncoiling device of the present utility model can perform the work of coiling and uncoiling at the same time. During the production and operation process, the number of coiling and uncoiling equipment for the coil can be reduced, and then more workpieces can be vacated to place other production equipment, thereby improving the overall production efficiency.

[0028] The specific structures of the coaxial reverse mechanism 4 and the rotating shaft 6 are described as follows:

[0029] The coaxial reverse mechanism 4 further includes a planet carrier 41, planet gears 43 and a transmission gear 44. The planet gears 43 are rotatably sleeved on the sun gear 42. There are three planet gears 43, and the three planet gears 43 are arranged around the sun gear 42. One planet gear 43 passes through the planet carrier 41 and meshes with the transmission gear 44. The planet gears 43 and the transmission gear 44 are arranged on the planet carrier 41 in the same direction. The sun gear 42 meshes with the planet gears 43, the planet gears 43 mesh with the transmission gear 44, and the transmission gear 44 meshes with the reverse wheel 45. When the driving mechanism 2 is started, it outputs torque to the sun gear 42. The sun gear 42 directly outputs part of the torque to a material roll 3 through the rotating shaft 6. At the same time, the sun gear 42 sequentially transmits the remaining torque to the other material roll 3 through the planet gears 43 and the transmission gear 44. The coaxial reverse rotation of the two material rolls 3 is realized.

[0030] Further, an internal spline 47 is arranged in the reverse groove 46, and an external spline 51 is arranged on the bushing 5. The internal spline 47 and the external spline 51 are meshed to transmit torque, and the key connection method is convenient for disassembly and assembly. In addition, the connection between the rotating shaft 6 and the sun gear 42 is also a key connection.

[0031] Furthermore, the diameter of part of the rotating shaft 6 is reduced to form a step 61, and the bushing 5 is sleeved on the step 61, so that the outer surface of the bushing 5 is flush with the outer surface of the non-step 61 part of the rotating shaft 6. That is, the reserved space at the center position can be the same when the two material rolls 3 are installed, which simplifies the installation.

[0032] The specific structure of the material roll 3 is described as follows:

[0033] The material roll 3 includes an inner support plate 33 which is arranged along the axis direction of the rotating shaft 6. At least three inner support plates 33 are provided, and the three inner support plates 33 are arranged radially around the bushing 5 or the rotating shaft 6. An arc-shaped plate 34 is also provided. An outer support plate 35 is provided on the concave surface of the arc-shaped plate 34. The arc-shaped plate 34 and the inner support plate 33 are arranged in the same direction, and the outer support plate 35 is connected to the inner support plate 33. The contact area between the arc-shaped plate 34 and the wound coil material is large, the force is dispersed, and the damage to the coil material when the material roll 3 winds the coil material is reduced.

[0034] Furthermore, the material roll 3 further includes a baffle 31 which is perpendicular to the rotating shaft 6 and simultaneously connects all the inner support plates 33. A limiting groove 32 is formed on the baffle 31, and the arc-shaped plate 34 is inserted into the limiting groove 32 to enhance the installation strength of the arc-shaped plate 34.

[0035] The specific structures of the base 1 and the driving mechanism 2 are described as follows:

[0036] The driving mechanism 2 can be a motor. The torque output by the motor is stable and the response is fast, which improves the overall operation stability of the coil material winding and unwinding device and quickly adapts to the load change. It also includes a base 1, and the driving mechanism 2 is arranged on the base 1. The base 1 can accommodate the power supply and circuits of the driving mechanism 2.

[0037] The specific working process of the present utility model is as follows:

[0038] Taking one material roll 3 for winding and one material roll 3 for unwinding as an example. According to the bending direction of the more coiled coil material, one end of the coil material to be wound is connected to the material roll 3 for winding. The coiled coil material is sleeved on the material roll 3 for unwinding, and one end of the coil material is connected to the processing equipment, and then the driving mechanism 2 is started. When the mechanism starts, its output torque is given to the sun gear 42. The sun gear 42 directly outputs part of the torque to one material roll 3 through the rotating shaft 6; at the same time, the sun gear 42 sequentially transmits the remaining torque to the other material roll 3 through the planet gear 43 and the transmission wheel 44, realizing the coaxial reverse rotation of the two material rolls 3. That is, one material roll 3 winds the material and the other material roll 3 unwinds the material.

[0039] It can be seen that the above-mentioned coil material winding and unwinding device for diaphragm box production can perform the work of winding and unwinding at the same time. During the production and operation process, the number of coil material winding and unwinding equipment can be reduced, and then more workpieces can be vacated to place other production equipment, thereby improving the overall production efficiency.

[0040] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not conflict, it should be considered as the scope recorded in this specification.

[0041] The above embodiments only represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
