Description

Technical Field

[0001] This utility model relates to the field of large circular knitting machine technology, specifically to a stable transmission device for large circular knitting machines. Background Technology

[0002] Circular knitting machine is a common name for a core production equipment in the knitting industry. Its formal name is usually single-sided or double-sided circular knitting machine, and it is sometimes simply called a circular knitting machine. It is used to continuously and efficiently produce tubular knitted fabrics. When the circular knitting machine is in operation, it needs to transmit power to the knitting disc through a power motor and a transmission device to make it rotate. The yarn feeder then winds in the yarn and forms the fabric. The transmission device includes a rotating gear connected to the power motor and a gear ring fitted on the outer wall of the knitting disc that meshes with the rotating gear. The power output of the power motor to the knitting disc is transmitted through the transmission gear and the gear ring, causing it to rotate.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: when the existing transmission devices are in use, there is a certain gap between the knitting disc, the gear ring, and the base of the circular knitting machine. In addition, the knitting disc will generate a certain vibration during the weaving process, and when the transmission gear contacts the gear ring outside the knitting disc, a certain lateral force will be generated. Therefore, after long-term operation, the knitting disc or the transmission gear will develop a certain lateral offset. As a result, after working for a certain period of time, it is necessary to stop the machine for maintenance and reset it. Otherwise, the fabric pattern will easily become skewed due to the lateral offset of the knitting disc. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a stable transmission device for large circular knitting machines that is stable in transmission and does not easily cause the knitting disc to shift laterally.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a stable transmission device for a large circular knitting machine, comprising a knitting disc seat rotatably mounted on the base of the large circular knitting machine and connected to the knitting disc of the large circular knitting machine, and a gear ring fixedly sleeved on the outer wall of the knitting disc seat. The outer wall of the gear ring is meshed with a power gear connected to the power motor of the large circular knitting machine. Several driven gear columns with their bottoms movably engaged on the base of the large circular knitting machine are also evenly distributed between the outer walls of the gear ring. The top outer wall of the driven gear column is meshed with the outer wall of the gear ring.

[0006] A further improvement is that the power gear includes a base connected to the housing of the power motor and a through hole integrally formed on the base through which the rotating shaft of the power motor can pass. The top inner wall of the through hole is movably engaged with a transmission shaft whose bottom end is engaged with the rotating shaft of the power motor. The top end of the transmission shaft is provided with a transmission gear.

[0007] A further improvement is that the inner wall of the perforation is also provided with a fixing elastic block.

[0008] A further improvement is that the transmission gear includes a gear body and a retaining tooth integrally formed on the outer wall of the gear body, and a slot that penetrates the gear body is integrally formed at the center of the gear body.

[0009] A further improvement is that a slot is integrally formed on the side wall of the slot.

[0010] A further improvement is that the outer wall of the gear ring is also provided with a limiting ring for limiting the deformation of the driven gear column and the drive gear.

[0011] After adopting the above technical solution, the beneficial effects of this utility model are as follows: In the process of use, the power motor outputs power to the transmission shaft, which in turn causes the transmission gear to rotate and drives the gear ring to rotate, thereby causing the knitting disc base to rotate, thus causing the knitting disc mounted on it to rotate. At the same time, during the rotation, the gear ring is supported and restricted by the limiting ring in conjunction with several driven gear columns, so that it will not have lateral deviation during the rotation, thereby improving its stability during the rotation process and avoiding the phenomenon of skewed fabric patterns.

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] See Figure 1-3As shown, the technical solution adopted in this specific embodiment is: a stable transmission device for a circular knitting machine, including a knitting disc base 1 rotatably mounted on the base of the circular knitting machine and connected to the knitting disc of the circular knitting machine, and a gear ring 2 fixedly sleeved on the outer wall of the knitting disc base 1. A power gear 5 connected to the power motor of the circular knitting machine is meshed on the outer wall of the gear ring 2. Several driven gear columns 6 with their bottoms movably engaged with the base of the circular knitting machine are also evenly distributed between the outer walls of the gear ring 2. The top outer wall of the driven gear column 6 is meshed with the outer wall of the gear ring 2. The top of the driven gear column 6 is a gear, and it has a downwardly extending column. The bottom end of the column is connected to the base of the circular knitting machine through a bearing. The connection methods are all existing technologies and will not be described in detail here. The power gear 5 includes a base 51 connected to the housing of the power motor and a through hole 52 integrally formed on the base 51 for the power motor's rotating shaft to pass through. The inner wall of the top of the through hole 52 is movably engaged with a transmission shaft 53 whose bottom end is engaged with the power motor's rotating shaft. The top of the transmission shaft 53 is provided with a transmission gear 54. The transmission gear 54 includes a gear body 541 and a retaining tooth 543 integrally formed on the outer wall of the gear body 541. The center of the gear body 541 has an integrally formed slot 542 that penetrates the gear body 541. In use, the needle is... The knitting disc is installed on the knitting disc base 1, and the knitting disc base 1 is then movably fitted into the base of the circular knitting machine. A gear ring 2 is then fixedly fitted onto the outer wall of the knitting disc base 1, and a power gear 5 is installed on the power motor of the circular knitting machine. The rotating shaft at the top of the power motor is inserted into the through hole 52, and its top end is connected to the transmission shaft 53. The bottom of the transmission shaft 53 can have a hexagonal or quadrilateral groove, and the top end of the rotating shaft of the power motor can be shaped to fit into the groove, allowing for insertion and connection. Thus, when the power motor rotates, the transmission gear 54 also rotates synchronously, thereby causing... The locking teeth 543, which mesh with the gear ring 2, rotate under the drive of the gear body 541, thereby outputting the power from the power motor to the gear ring 2, causing the gear ring 2 to rotate, which in turn drives the knitting disc seat 1 to rotate, and then causes the knitting disc to rotate. During the rotation, the outer wall of the top of the driven gear column 6 meshes with the outer wall of the gear ring 2. Through several evenly distributed gears on the top of the driven gear column 6, the gear ring 2 is passively rotated by meshing with it, so that the gear ring 2 is held in place by the driven gear column 6 and the power gear 5. This prevents the gear ring 2 from lateral swaying when it is driven by the power gear 5, thus improving the stability of the large circular knitting machine during operation.

[0018] The inner wall of the perforation 52 is also provided with a fixed elastic block 55. The fixed elastic block 55 can be a rubber block structure, which is beneficial to fill the gap between the perforation 52 and the rotating shaft of the power motor, thereby preventing the rotating shaft of the power motor from wobbling when rotating, and further improving the stability of the transmission device.

[0019] The slot 542 also has an integrally formed groove 544 on its side wall, which is conducive to engaging the slot 543 with the protrusion of the drive shaft 53 through the groove 544, so as to make the connection between the slot 543 and the drive shaft 53 more secure and avoid slippage affecting power transmission.

[0020] The outer wall of the gear ring 2 is also provided with a limiting ring 3 for limiting the deformation of the driven gear column 6 and the drive gear 5. The bottom of the limiting ring 3 is fixed on the base of the large circular machine. There is a small gap between the limiting ring 3 and the driven gear column 6 and the drive gear 5, so that the deformation range of the driven gear column 6 and the drive gear 5 is controlled. This helps to avoid the lateral force causing excessive deformation of the driven gear column 6 and the drive gear 6, which would affect the support effect on the gear ring 2.

[0021] The working principle of this utility model is as follows: When using this utility model, the knitting disc is installed on the knitting disc base 1, and the knitting disc base 1 is movably fitted into the base of the circular knitting machine. Then, a gear ring 2 is fixedly fitted onto the outer wall of the knitting disc base 1, and a power gear 5 is installed on the power motor of the circular knitting machine. The rotating shaft at the top of the power motor is inserted into the through hole 52, and its top end is connected to the transmission shaft 53. The bottom of the transmission shaft 53 can have a hexagonal or quadrilateral groove, and the top end of the rotating shaft of the power motor can be shaped to fit into the groove, thus allowing for insertion and connection. Therefore, when the power motor rotates, the transmission gear 54... Simultaneously, rotation is generated, causing the locking teeth 543, which mesh with the gear ring 2, to rotate under the drive of the gear body 541. This outputs the power from the motor to the gear ring 2, causing it to rotate and drive the knitting disc base 1 to rotate, thus causing the knitting disc to rotate. During the rotation, the outer wall of the top of the driven gear column 6 meshes with the outer wall of the gear ring 2. Through several evenly distributed gears on the top of the driven gear column 6, the gear ring 2 is passively rotated by meshing with it. This causes the gear ring 2 to be held in place by the driven gear column 6 and the power gear 5, thus preventing lateral swaying when the gear ring 2 is driven by the power gear 5, improving the stability of the large circular knitting machine during operation.
