Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, and more specifically, to a main shaft transmission mechanism of a winding machine. Background Art

[0002] With the development of the electronics industry, the demand for inductors is increasing, because most electrical products need to be wound with enameled copper wire into inductors, which are devices that work on the principle of electromagnetic induction. Winding machines are equipment used to wind various types of coils including inductors, electronic rotors and other coils.

[0003] In the prior art, the spindle transmission mechanism is the heart of the winding machine. The quality of winding and the stability of winding work are closely related to the spindle transmission mechanism. At present, in the spindle transmission mechanism of conventional winding machines, the synchronous belt connecting the motor spindle and one of the working spindles is too long. During use, the synchronous belt is easily stretched by force, causing the synchronous wheel to jump teeth, resulting in the working spindle turns being out of sync and inaccurate. In addition, the tension of the synchronous belt is insufficient during operation, and the vibration is large, which easily causes the winding machine to vibrate violently and generate loud noise.

[0004] Therefore, it is necessary to provide a main shaft transmission mechanism of a winding machine to solve the above problems. Utility Model Content

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A spindle transmission mechanism of a winding machine comprises a fixed plate and a motor detachably connected thereto, a driving wheel is arranged on the output shaft of the motor, a plurality of array-distributed working spindles are rotatably connected to the fixed plate, the working spindles penetrate the fixed plate and are respectively provided with a coil fixture and a follower wheel at both ends, the follower wheel and the motor are located on the same side of the fixed plate,

[0008] The plurality of follower wheels are divided into two symmetrically arranged groups, the driving wheel is located on the symmetry axis of the two groups of follower wheels and there is a height difference between the driving wheel and the two groups of follower wheels, the driving wheel is respectively connected to the two groups of follower wheels through two synchronous belts, one synchronous belt passes through the surfaces of two follower wheels in one group of follower wheels, and the adjacent follower wheels in the same group are sequentially connected through synchronous belt 2.

[0009] The technical solution of the utility model is further configured as follows: the synchronous belt passes through the surfaces of the two follower wheels in one group of the follower wheels which are closest to the other group of the follower wheels.

[0010] The technical solution of the utility model is further configured as follows: the fixed plate is provided with a tensioning wheel respectively abutting against an outer surface of the two synchronous belts, and the height of the tensioning wheel is located between the driving wheel and the two groups of driven wheels.

[0011] The technical solution of the utility model is further configured as follows: the number of the tensioning wheels that abut against the outer surface of one of the synchronous belts is set to two, and the two tensioning wheels respectively abut against two ends of one of the synchronous belts passing through the driving wheel.

[0012] The technical solution of the utility model is further configured as follows: a fixing box for shielding the two groups of follower wheels is detachably connected to the fixing plate, and cooling fans are provided at both ends of the fixing box in the length direction.

[0013] The technical solution of the utility model is further configured as follows: an opening for accommodating the tensioning wheel and the synchronous belt is opened on the fixed box.

[0014] The technical solution of the utility model is further configured as follows: the fixing plate is detachably connected to a plurality of support rods located in the fixing box, and one end of the plurality of support rods away from the fixing plate is detachably connected to the fixing box.

[0015] The technical solution of the utility model is further configured as follows: the fixing plate is detachably connected to a motor fixing frame, and the motor is detachably connected to the motor fixing frame.

[0016] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0017] Through the setting of the structure, a synchronous belt can pass through the driving wheel and the surfaces of two adjacent follower wheels in a group of follower wheels at the same time, forming a cross-sectional structure that is approximately triangular, thereby ensuring the tension of the synchronous belt and preventing tooth jumping as much as possible to ensure that the number of turns of the working spindle is accurately synchronized with the output shaft of the motor. The setting of the tensioning wheel makes the synchronous belt present an approximately S-shaped cross-sectional structure when passing through the tensioning wheel, thereby ensuring the stability of the tension of the synchronous belt, thereby reducing vibration and effectively reducing noise. In addition, this method increases the contact area, making the driving wheel and the follower wheel run more smoothly and with higher precision. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model. Example

[0024] refer to Figures 1 to 4 As shown, the utility model provides a spindle transmission mechanism of a winding machine, including a fixed plate 1 and a motor fixing frame 14 detachably connected thereto, the motor fixing frame 14 is detachably connected to a motor 2, a driving wheel 3 is provided on the output shaft of the motor 2, a plurality of array-distributed working spindles 4 are rotatably connected to the fixed plate 1, the working spindle 4 passes through the fixed plate 1 and a coil fixture 5 and a follower wheel 6 are respectively provided at both ends thereof, and the follower wheel 6 and the motor 2 are located on the same side of the fixed plate 1.

[0025] refer to Figures 1 to 4 As shown, there are a total of 12 follower wheels 6, which are divided into two symmetrically arranged groups. The driving wheel 3 is located directly below the two groups of follower wheels 6. The driving wheel 3 is connected to the two groups of follower wheels 6 through two synchronous belts 1 7. The synchronous belt 1 7 passes through the surfaces of the two follower wheels 6 in one group that are closest to the other group of follower wheels 6. The adjacent follower wheels 6 in the same group are connected in sequence through the synchronous belt 2 8.

[0026] Through the arrangement of the above structure, the two synchronous belts 7 passing through the driving wheel 3 can respectively drive the two groups of follower wheels 6 to rotate. In this way, a large number of working spindles 4 can be driven, and 12 or even more working spindles 4 can work at the same time. The speed is high and the number of axes is large, which greatly improves the equipment efficiency and can meet large-scale industrial production. Moreover, the driving wheel 3 is transmitted to a total of four follower wheels 6 in the two groups of follower wheels 6. These four follower wheels 6 are located in the most central area, which can make the driving wheel 3 and the follower wheel 6 run more smoothly and with higher precision.

[0027] refer to Figures 1 to 4As shown, the fixed plate 1 is provided with tensioning wheels 9 which respectively abut against the outer surfaces of the two synchronous belts 7, and the number of tensioning wheels 9 abutting against the outer surface of one synchronous belt 7 is set to two, and the height of the tensioning wheel 9 is located between the driving wheel 3 and the two sets of driven wheels 6, and the two tensioning wheels 9 respectively abut against the two ends of a synchronous belt 7 passing through the driving wheel 3.

[0028] Through the arrangement of the above-mentioned structure, the tensioning wheel 9 can make the synchronous belt 7 passing through the tensioning wheel 9 present an approximately S-shaped cross-sectional structure at this location, so as to ensure the stability of the tension of the synchronous belt 7, thereby reducing vibration and effectively reducing noise. The stable tension can also avoid tooth jumping as much as possible, so as to ensure that the number of turns of the working spindle 4 is accurately synchronized with the output shaft of the motor 2.

[0029] refer to Figures 1 to 4 As shown, a fixed box 10 for shielding two sets of follower wheels 6 is provided on the fixed plate 1, and the fixed box 10 is detachably connected to the fixed plate 1 through a plurality of support rods 13 located inside the fixed box 10, one end of the plurality of support rods 13 is detachably connected to the fixed plate 1, and the other ends of the plurality of support rods 13 are detachably connected to the inner wall of the fixed box 10, cooling fans 11 are provided at both ends of the top wall of the fixed box 10 in the length direction, and an opening 12 for accommodating the tensioning wheel 9 and the synchronous belt 7 is provided on the bottom wall of the fixed box 10.

[0030] Through the arrangement of the above structure, the heat generated by the cooling fan 11 on the fixed box 10 during operation can be discharged in time to avoid excessive temperature. Moreover, when the synchronous belt 1 7 or the synchronous belt 2 8 needs to be adjusted or replaced, the fixed box 10 can be removed from the support rod 13 and the fixed plate 1 for easy operation. The existence of the opening 12 reserves sufficient space for the tensioning wheel 9 and the synchronous belt 1 7.

[0031] refer to Figures 1 to 4 As shown, when the spindle transmission mechanism of the winding machine starts to work, the motor 2 on the motor fixing frame 14 is started, so that its output shaft drives the driving wheel 3 to rotate, and the driving wheel 3 drives the four follower wheels 6 located in the central area of ​​the fixed plate 1 to rotate through the two synchronous belts 1 7, so that the four follower wheels 6 drive the remaining follower wheels 6 to rotate in turn through the synchronous belt 2 8, and the rotating follower wheels 6 can make the working spindle 4 and the coil fixture 5 rotate, so as to complete the winding work of the inductor coil. In this process, the tensioning wheel 9 controls the tensioning force of the two synchronous belts 7 to ensure the stable transmission and operation of the entire spindle transmission mechanism.

[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
