Description

Technical Field

[0001] This utility model relates to the field of power transmission device technology, specifically a disc-type continuously rotating multi-axis power transmission device. Background Technology

[0002] Most current non-stop winding devices adopt a 2-station winding shaft turntable design, with only two winding stations on the turntable. This limits the number of working positions on the equipment, making it difficult to incorporate operations that could improve automation, such as core gluing, automatic core loading, and roll sealing. Figure 1 As shown, this is mainly because existing rotary winding shaft power transmission devices in winding equipment can generally only be equipped with two power shafts on a continuously rotating turntable, and two drive motors (e.g., Figure 1 The drive motors (A and B) in the original design correspond one-to-one. Power is transmitted from these two shafts to two fixed turntables via a complex multi-layered shaft system on the central shaft of the turntable. The power is then transmitted to the two auxiliary shafts via synchronous belts. This method is complex, difficult to assemble, and can only transmit power to the two shafts on the turntable separately. The aforementioned power transmission device is costly, inflexible, and can only drive a limited number of shafts. Therefore, it is necessary to develop a relatively simple multi-axis power transmission device that can drive a larger number of continuously rotating discs to overcome these shortcomings.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the ordinary skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] The utility model provides a kind of multi-shaft power transmission device of disc type continuous rotation, comprising: fixed plate 1, carousel 2, shaft A, shaft B, shaft C, shaft D, first motor 3, second motor 4, first double-sided synchronous belt 5, second double-sided synchronous belt 6 and tension pulley device 7.Carousel 2 is rotatably arranged on fixed plate 1, first motor 3 and second motor 4 are respectively arranged at the left and right sides of carousel 2 with interval, first motor 3 is equipped with first synchronous pulley group 8 on its output shaft, second motor 4 is equipped with second synchronous pulley group 9 on its output shaft, and tension pulley device 7 is arranged on fixed plate 1 and above carousel 2.In addition, the utility model can also include bottom plate 17, and fixed plate 1 is arranged on bottom plate 17.

[0025] Shaft A, shaft B, shaft C and shaft D are rotatably arranged at four corners of carousel 2 respectively, and shaft A and shaft C are diagonally arranged, and shaft B and shaft D are diagonally arranged, and shaft A is equipped with shaft A synchronous pulley group 10, shaft B is equipped with shaft B synchronous pulley group 11, shaft C is equipped with shaft C synchronous pulley group 12, and shaft D is equipped with shaft D synchronous pulley group 13.

[0026] The above-mentioned first synchronous pulley group 8, second synchronous pulley group 9, shaft A synchronous pulley group 10, shaft B synchronous pulley group 11, shaft C synchronous pulley group 12 and shaft D synchronous pulley group 13 all include two synchronous pulleys, and the length and transmission path of first double-sided synchronous belt 5 and second double-sided synchronous belt 6 are same, and first double-sided synchronous belt 5 and second double-sided synchronous belt 6 are connected with first synchronous pulley group 8, tension pulley device 7 and second synchronous pulley group 9, and first double-sided synchronous belt 5 is located between carousel 2 and second double-sided synchronous belt 6.

[0027] It should be understood that when turntable 2 rotates, it can synchronously drive four shafts, namely shafts A, B, C, and D, to rotate simultaneously. Based on the power analysis of the four shafts, only two shafts need to be driven at a time within the power zone of the first double-sided synchronous belt 5 and the second double-sided synchronous belt 6. However, the driving process of shafts A, B, C, and D exhibits a continuous cyclical characteristic. Therefore, this invention sets up two drive motors, a first motor 3 and a second motor 4, and two sets of synchronous belts, the first double-sided synchronous belt 5 and the second double-sided synchronous belt 6, with identical paths. Simultaneously, synchronous pulley sets in a "one drive plus one follower" configuration are set on each motor output shaft and each driven shaft. Through the above structural settings, a power distribution is formed where the first motor 3 drives shafts A and C via the first double-sided synchronous belt 5, and the second motor 4 drives shafts B and D via the second double-sided synchronous belt 6, ensuring a reasonable distribution of the driving conditions of the four shafts.

[0028] The various working states of the disc-type continuously rotating multi-axis power transmission device of this utility model are as follows: Working state (1): such as Figure 4 As shown, shafts A and D are located at working positions two and one in the power zone, respectively. The first motor 3 provides power to shaft A via the first double-sided synchronous belt 5, and the second motor 4 transmits power to shaft D via the second double-sided synchronous belt 6 along the same route. Working state (2): As shown... Figure 5 As shown, the four shafts rotate at a certain angle under the drive of turntable 2. Shafts A and D still maintain power. The wrapping routes of the first double-sided synchronous belt 5 and the second double-sided synchronous belt 6 to each synchronous pulley group change, but the length does not change much. The synchronous belts maintain a taut and effective transmission state under the action of tensioning wheel device 7. Working state (3): as shown Figure 6 As shown, the four axes continue to rotate at a certain angle under the drive of turntable 2, and shaft A is separated from the first double-sided synchronous belt 5 and the second double-sided synchronous belt 6, that is, shaft A leaves the power zone and is in a non-powered state. Working state (4): as Figure 7 As shown, the four axes continue to rotate at a certain angle under the drive of turntable 2. Shaft C is wrapped by the synchronous belt, that is, shaft C enters the power zone, and the first motor 3 provides power to shaft C through the first double-sided synchronous belt 5. Working state (5): as Figure 8 As shown, the four shafts continue to rotate at a certain angle under the drive of turntable 2. Similar to the above working state (2), shafts D and C still have power. The wrapping path of the synchronous belt around each synchronous pulley group changes, but the length does not change much. Under the action of tensioning wheel device 7, it maintains a taut and effective transmission state. Working state (6): as shown Figure 9 As shown, the four axes continue to rotate at a certain angle, with shafts D and C respectively in working position two and working position one in the power zone. The second motor 4 provides power to shaft D through the second double-sided synchronous belt 6, and the first motor 3 transmits power to shaft C through the first double-sided synchronous belt 5.

[0029] Specifically, the fixed plate 1 is provided with a motor mounting plate 14, and the first motor 3 and the second motor 4 are arranged at the left and right ends of the motor mounting plate 14 respectively. Preferably, the motor mounting plate 14 is arranged in an inclined manner, that is, the first motor 3 and the second motor 4 are also arranged in an inclined manner.

[0030] Specifically, the tension pulley device 7 comprises a connecting plate 15, a first tension pulley, a second tension pulley and a cylinder 16. The connecting plate 15 is rotatably arranged on the fixed plate 1, the first tension pulley and the second tension pulley are arranged at one end of the connecting plate 15, and the cylinder 16 is arranged on the fixed plate 1 and connected with the other end of the connecting plate 15. The first double-sided synchronous belt 5 is connected with the first tension pulley, and the second double-sided synchronous belt 6 is connected with the second tension pulley.

[0031] It should be understood that, in view of the fact that the positions of the driven shafts on the continuously rotatable turntable are always changing, the utility model selects long-path synchronous belts to drive the above-mentioned four shafts. By using this soft connection driving, the deformability of the synchronous belts can be utilized to adapt to the deformation of the synchronous belts after the positions of the driven shafts change. In addition, the utility model sets the synchronous belts used for transmission as double-sided synchronous belts, and makes the fixed positions of the two driving motors be inclined to a certain extent. In addition, a tension pulley device with a cylinder is arranged in the wrapping path of the synchronous belts to control the tension. The wrapping path of the synchronous belts of the utility model can well adapt to the moving path of the driven shafts. During the movement of the above-mentioned four shafts along with the turntable, the change of the wrapping lengths of the first double-sided synchronous belt and the second double-sided synchronous belt can be controlled within one thousandth, and this part of the change in length can also be timely absorbed by the tension pulley device, so as to ensure the effective transmission process of the synchronous belts.

[0032] Compared with the prior art, the utility model provides a disc type continuously rotatable multi-shaft power transmission device, which has the following beneficial effects: the utility model applies two long-path double-sided synchronous belts to transmit power. Through the analysis of the movement track of the driven shafts on the turntable and the position setting of the driving motors, more shafts can be driven more efficiently and flexibly by using a relatively simple mechanical structure, without using the complex multi-layer sleeve shafts of the prior art. Through the use of the utility model, the disc type continuously rotatable power transmission device can realize the driving of one more shafts than the prior art by using a simpler structure when the driving motors are also two, which greatly saves the equipment cost and greatly increases the multifunctionality and automation degree of the equipment.
