[0002] Circular knitting machine, scientifically known as circular weft knitting machine, has developed rapidly due to its multiple loop forming systems, high speed, high output, fast pattern change, good fabric quality, fewer processes and strong product adaptability. The circular knitting machine is composed of a frame, a yarn supply mechanism, a transmission mechanism, a lubrication and dust removal mechanism, an electrical control mechanism, a pulling and winding mechanism and other auxiliary devices.

[0003] The transmission mode of the circular knitting machine when it is working is that the motor drives the two transmission gears in the transmission mechanism, and then one of the transmission gears drives the large ding gear and the middle shaft. Since the transmission torque of the large ding gear and the transmission gear is large, and errors are prone to occur during the installation process, resulting in uneven meshing between the two, which in turn causes the two to easily wear when working. Therefore, it is necessary to regularly apply lubricating oil to their surfaces to reduce wear. However, the existing operation of applying lubricating oil is performed manually, which is more troublesome, the effect of applying is poor, and it is easy to cause waste of lubricating oil.

[0004] Therefore, a lubrication structure for a transmission mechanism of a knitting device is proposed. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] Example: See Figure 1-4 The utility model provides a technical solution: a lubrication structure for a transmission mechanism of a knitting device, comprising a large tripod 1, a transmission gear 2 and a large tripod gear 3 are arranged in the large tripod 1, and the transmission gear 2 and the large tripod gear 3 are meshed; a refueling cylinder 4 is installed on the large tripod 1, a piston 12 is slidably installed on the inner wall of the refueling cylinder 4, a sliding rod 11 is installed on the piston 12, and the sliding rod 11 is slidably installed on the refueling cylinder 4, an oil outlet pipe 5 is installed at the bottom of the refueling cylinder 4, a sponge 6 is installed at the bottom of the oil outlet pipe 5, and the sponge 6 is in contact with the transmission gear 2, an oil inlet pipe 7 is installed on one side of the refueling cylinder 4, and a connecting pipe 8 is installed on one side of the oil inlet pipe 7 A connecting pipe 8 passes through the top of the big tripod 1 and is installed with an oil storage box 9. The oil storage box 9 is installed on the big tripod 1. An oil filling pipe 10 is installed on the oil storage box 9. A rotating shaft 20 is installed on the inner walls of the oil outlet pipe 5 and the oil inlet pipe 7. Sealing plates 21 are rotatably installed on the two rotating shafts 20. The two sealing plates 21 are respectively in contact with the bottom of the refueling cylinder 4 and the inner wall of the oil inlet pipe 7. A positioning hole 23 is opened on the sealing plate 21. The rotating shaft 20 is rotatably installed in the positioning hole 23. A torsion spring 22 is sleeved on the rotating shaft 20. One end of the torsion spring 22 is installed on the rotating shaft 20, and the other end of the torsion spring 22 is installed on the inner wall of the positioning hole 23.

[0021] Furthermore, an adapter plate 13 is installed on the sliding rod 11, and a movable plate 15 is movably installed on the adapter plate 13. An L-shaped support plate 17 is installed on the refueling cylinder 4, and a motor 16 is installed on the L-shaped support plate 17. The output shaft of the motor 16 is installed on the movable plate 15. An adapter hole 19 is opened on the adapter plate 13, and a drive shaft 14 is installed on the movable plate 15. The drive shaft 14 is movably installed in the adapter hole 19. When it is necessary to apply lubricating oil to the transmission gear 2 and the large tripod gear 3, the motor 16 is started, and the electric The rotation of the motor 16 drives the movable plate 15 to rotate, and the rotation of the movable plate 15 drives the drive shaft 14 to rotate and slide in the adapter hole 19 of the adapter plate 13, thereby driving the sliding rod 11 to slide up and down. When the drive shaft 14 rotates upward, it drives the sliding rod 11 and the piston 12 to slide upward. Under the action of pressure, the sealing plate 21 in the oil outlet pipe 5 will be tightly closed at the bottom of the refueling cylinder 4, and the sealing plate 21 in the oil inlet pipe 7 will rotate and open, and at the same time, the torsion spring 22 will be deformed, so that the oil in the oil storage box 9 can be released. The lubricating oil is drawn into the refueling cylinder 4. When the driving shaft 14 rotates downward, the sliding rod 11 and the piston 12 are driven to slide downward. Therefore, under the action of pressure, the sealing plate 21 in the oil inlet pipe 7 will rotate back to its original position under the rebound action of the torsion spring 22, blocking the oil inlet of the oil inlet pipe 7 to prevent the lubricating oil from flowing back into the connecting pipe 8 and the oil storage box 9. At the same time, the sealing plate 21 in the oil outlet pipe 5 will rotate and open, so that when the piston 12 slides downward, the lubricating oil in the refueling cylinder 4 can be squeezed into the sponge 6 and evenly applied to the transmission gear 2. When the transmission gear 2 and the large tripod gear 3 are meshed and rotated, the lubricating oil can adhere to the large tripod gear 3 for lubrication. Therefore, before applying the lubricating oil, it is only necessary to add the lubricating oil that needs to be applied once to the oil storage box 9 through the oil filling pipe 10, start the motor 16, and through its reciprocating operation, the lubricating oil in the oil storage box 9 can be evenly applied to the transmission gear 2. No manual operation is required, and the application effect is better, and no waste of lubricating oil will be caused.

[0022] Furthermore, limit rods 18 are slidably installed on both sides of the adapter plate 13, and the limit rods 18 are installed on the top of the refueling cylinder 4. The limit rods 18 can limit the stable up and down sliding of the adapter plate 13 when the motor 16 rotates, thereby continuously driving the piston 12 to extract or squeeze out the lubricating oil.

[0023] The working principle is as follows: before applying the lubricating oil, first add the lubricating oil that needs to be applied once into the oil storage box 9 through the oil filling pipe 10, then start the motor 16, the rotation of the motor 16 drives the movable plate 15 to rotate, and under the limiting action of the limiting rod 18, the movable plate 15 rotates to drive the drive shaft 14 to rotate and slide in the adapter hole 19 of the adapter plate 13, thereby driving the sliding rod 11 to slide up and down, and when the driving shaft 14 rotates upward, it drives the sliding rod 11 and the piston 12 to slide upward, and under the action of pressure, the sealing plate 21 in the oil outlet pipe 5 will be tightly closed at the bottom of the refueling cylinder 4, and the sealing plate 21 in the oil inlet pipe 7 will rotate and open, and at the same time, the torsion spring 22 will be deformed, thereby the lubricating oil in the oil storage box 9 can be drawn into the refueling cylinder 4 When the driving shaft 14 rotates downward, the sliding rod 11 and the piston 12 are driven to slide downward. Therefore, under the action of pressure, the sealing plate 21 in the oil inlet pipe 7 will rotate back to its original position under the rebound action of the torsion spring 22, blocking the oil inlet of the oil inlet pipe 7 to prevent the lubricating oil from flowing back into the connecting pipe 8 and the oil storage box 9. At the same time, the sealing plate 21 in the oil outlet pipe 5 will rotate open, so that when the piston 12 slides downward, the lubricating oil in the refueling cylinder 4 can be squeezed into the sponge 6 and evenly applied to the transmission gear 2. When the transmission gear 2 is meshed and rotated with the large tripod gear 3, the lubricating oil can adhere to the large tripod gear 3 for lubrication, thereby eliminating the need for manual operation alone, and the application effect is better, and no waste of lubricating oil will be caused.
