An oil circuit lubricating mechanism for a flat knitting machine needle punch press

Abstract

This utility model discloses an oil circuit lubrication mechanism for a flat knitting machine needle punch, relating to the field of oil circuit lubrication technology. It includes a main body with a moving mechanism at its rear end, comprising a rack and a half-gear. The rack is fixedly connected to the front end of the main body, and the half-gear is meshed with the upper end of the rack. When the main body lubricates the parts of the flat knitting machine needle punch, the motor is started, and the rotating disk drives the abutment to rotate. Since the abutment is within a rectangular groove of a long rod, and the long rod is connected to a fixed shaft, the long rod drives the half-gear to oscillate. The oscillation of the half-gear drives the rack to reciprocate, which in turn drives the main body to reciprocate. During this reciprocating motion, the main body can cover the two ends of the needle bed, the edges of the needle movement trajectory, or the corners of the triangular system with oil, preventing dry or semi-dry friction of the parts and thus avoiding a reduction in the service life of the parts, ensuring that the knitting accuracy and product quality are not affected.

Description

Technical Field

[0001] This utility model relates to the field of oil circuit lubrication technology, and in particular to an oil circuit lubrication mechanism for a flat knitting machine needle punch. Background Technology

[0002] The oil lubrication mechanism of a flat knitting machine is a crucial device for ensuring the normal operation of the machine. It primarily uses an oil pump to deliver lubricating oil to various parts requiring lubrication, such as the needle bed, knitting needles, and the cam system. This mechanism continuously and stably supplies an appropriate amount of lubricating oil during operation, forming an oil film to reduce friction between parts, decrease wear, and thus extend the service life of parts, ensuring the knitting accuracy of the flat knitting machine. Simultaneously, it also plays a role in heat dissipation, preventing damage or deformation of parts due to excessive heat generated by friction. Furthermore, some oil lubrication mechanisms also have a filtration function, removing impurities from the lubricating oil, maintaining its cleanliness, and further protecting the equipment, enabling it to operate efficiently and stably under good lubrication conditions.

[0003] However, during the implementation of the above technical solution, at least the following technical problems were found:

[0004] The oil circuit lubrication mechanism of the flat knitting machine needle punch can only lubricate a single area. The two ends of the needle bed, the edge of the needle movement trajectory, or the corner parts of the cam system may not be covered by the fixed oil circuit, resulting in dry or semi-dry friction. This will aggravate the wear of parts, shorten the service life, and even cause failures such as needle breakage and cam wear and deformation, affecting the knitting accuracy and product quality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an oil circuit lubrication mechanism for a flat knitting machine needle punch, which solves the problem that existing oil circuit lubrication mechanisms for flat knitting machines can only lubricate a single area. The fixed oil circuit may not be able to cover the two ends of the needle bed, the edge of the needle movement trajectory, or the corner parts of the cam system, resulting in dry or semi-dry friction, which aggravates the wear of parts, shortens the service life, and may even cause needle breakage, cam wear and deformation, and other faults, affecting knitting accuracy and product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A lubrication mechanism for a flat knitting machine needle punch includes a main body. A moving mechanism is provided at the rear end of the main body, including a rack and a half gear. The rack is fixedly connected to the front end of the main body. The half gear is meshed with the upper end of the rack. A long rod is fixedly connected to the upper end of the half gear. A horizontal plate is provided at the front end of the rack. A connecting plate two is fixedly connected to the upper end of the horizontal plate. A fixed shaft is fixedly connected to the rear end of the connecting plate two. The fixed shaft is rotatably connected to the lower end of the long rod.

[0008] Preferably, the upper end of the connecting plate two is fixedly connected to the connecting plate one, and the rear surface of the connecting plate one is movably connected to a rotating disk.

[0009] Preferably, a rotating shaft is rotatably connected to the center point of the rear surface of the connecting plate, and the center point of the rotating disk is fixedly connected to the rotating shaft.

[0010] Preferably, a motor is fixedly connected to the front surface of the connecting plate, and the output port of the motor passes through the connecting plate and is fixedly connected to the rotating shaft.

[0011] Preferably, a rectangular groove is formed through the side surface of the long rod, and a stop post is provided inside the rectangular groove. The front end of the stop post is fixedly connected to the rotating disk.

[0012] Preferably, a slot is formed through the side surface of the horizontal plate, and a sliding rod is installed inside the slot.

[0013] Preferably, both ends of the slide rod are fixedly connected to the inner wall of the cross plate.

[0014] Preferably, a movable block is fixedly connected to the front surface of the rack, and the movable block is movably sleeved with the slide rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. When the main body of the device lubricates the parts of the flat knitting machine needle punch, the motor is started. The motor drives the rotating shaft and the rotating disk to rotate. The rotating disk drives the abutment to rotate. Since the abutment is in the rectangular groove of the long rod and the long rod is connected to the fixed shaft, the long rod will drive the half gear to swing. When the half gear swings, it will drive the rack to reciprocate. The rack will drive the main body of the device to reciprocate. When the main body of the device reciprocates, it can cover the two ends of the needle bed, the edge of the needle movement trajectory, or the corner parts of the triangular system with oil, avoiding dry friction or semi-dry friction of the parts, which would reduce the service life of the parts and ensure that the knitting accuracy and product quality are not affected.

[0017] II. The combined design of the slide bar and the moving block provides a precise straight guide path for the moving block by using a rigid rod slide bar in the slot of the horizontal plate, ensuring that the reciprocating motion of the moving block and the connected rack is stable and does not deviate. At the same time, the movable connection between the moving block and the slide bar can reduce frictional resistance, making the movement smoother, reducing vibration and noise, and avoiding impact damage to the parts.

[0024] This application provides an oil circuit lubrication mechanism for a flat knitting machine needle punch, which effectively solves the problem that the oil circuit lubrication mechanism for a flat knitting machine needle punch can only lubricate a single area. The two ends of the needle bed, the edge of the needle movement trajectory, or the corner parts of the cam system may not be covered by the fixed oil circuit, resulting in dry or semi-dry friction, which aggravates the wear of parts, shortens the service life, and may even cause faults such as needle breakage and cam wear and deformation, affecting the knitting accuracy and product quality.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that the oil circuit lubrication mechanism of the flat knitting machine needle punch can only lubricate a single area. Dry or semi-dry friction may occur at the two ends of the needle bed, the edges of the needle movement trajectory, or the corner parts of the cam system because the fixed oil circuit cannot cover them, thus aggravating wear of parts, shortening service life, and even causing needle breakage, cam wear and deformation, and other faults, affecting knitting accuracy and product quality. The overall approach is as follows:

[0027] To address the problems existing in the prior art, this utility model provides an oil circuit lubrication mechanism for a flat knitting machine needle punch, including a main body 11. A moving mechanism is provided at the rear end of the main body 11, including a rack 13 and a half gear 14. The rack 13 is fixedly connected to the front end of the main body 11, and the half gear 14 is meshed with the upper end of the rack 13. A long rod 15 is fixedly connected to the upper end of the half gear 14. When the main body 11 lubricates the parts of the flat knitting machine needle punch, a motor 19 is started. The motor 19 drives the rotating shaft 20 and the rotating disk 16 to rotate. A horizontal plate 12 is provided at the front end of the rack 13, and a connecting plate 21 is fixedly connected to the upper end of the horizontal plate 12. A fixed shaft 22 is fixedly connected to the rear end of the connecting plate 21. The fixed shaft 22 is rotatably connected to the lower end of the long rod 15. A connecting plate 18 is fixedly connected to the upper end of the connecting plate 21. A rotating disk 16 is movably connected to the rear surface of the connecting plate 18. A rotating shaft 20 is rotatably connected to the center point of the rear surface of the connecting plate 18. The center point of the rotating disk 16 is fixedly connected to the rotating shaft 20. A motor 19 is fixedly connected to the front surface of the connecting plate 18. The output port of the motor 19 passes through the connecting plate 18 and is fixedly connected to the rotating shaft 20. A rectangular groove 17 is opened through the side surface of the long rod 15. A stop post 25 is set inside the rectangular groove 17. The front end of the stop post 25 is fixedly connected to the rotating disk 16. The rotating disk 16 drives the stop post 25 to rotate. Since the stop post 25 is inside the rectangular groove 17 of the long rod 15 and the long rod 15 is connected to the fixed shaft 22, the long rod 15 will drive the half gear 14 to swing.

[0028] A slot is formed through the side surface of the horizontal plate 12, and a slide rod 23 is installed inside the slot. Both ends of the slide rod 23 are fixedly connected to the inner wall of the horizontal plate 12. A movable block 24 is fixedly connected to the front surface of the rack 13. The movable block 24 is movably sleeved with the slide rod 23. When the half gear 14 swings, it drives the rack 13 to reciprocate. The rack 13 drives the main body 11 of the device to reciprocate. When the main body 11 reciprocates, it can cover the two ends of the needle bed, the edge of the needle movement trajectory, or the corner of the triangular system with oil to prevent... This design avoids dry or semi-dry friction in parts, which could reduce their lifespan and ensure that weaving precision and product quality are not affected. The combination of slide bar 23 and moving block 24 provides a precise straight guide path for moving block 24 within the slot of horizontal plate 12 using rigid slide bar 23. This ensures that the reciprocating motion of moving block 24 and connected rack 13 is stable and does not deviate. At the same time, the movable connection between moving block 24 and slide bar 23 reduces frictional resistance, making the movement smoother, reducing vibration and noise, and preventing impact damage to parts.

[0029] Working principle:

[0030] In the first step, when the main body 11 of the device lubricates the parts of the flat knitting machine needle punch, the motor 19 is started. The motor 19 drives the rotating shaft 20 and the rotating disk 16 to rotate. The rotating disk 16 drives the abutment 25 to rotate. Since the abutment 25 is in the rectangular groove 17 of the long rod 15 and the long rod 15 is connected to the fixed shaft 22, the long rod 15 will drive the half gear 14 to swing. When the half gear 14 swings, it will drive the rack 13 to reciprocate. The rack 13 will drive the main body 11 of the device to reciprocate. When the main body 11 of the device reciprocates, it can cover the two ends of the needle bed, the edge of the needle movement trajectory, or the corner parts of the triangular system with oil, so as to avoid the dry friction or semi-dry friction of the parts, which would reduce the service life of the parts and ensure that the knitting accuracy and product quality are not affected.

[0031] The second step is the combination design of slide bar 23 and moving block 24. By using rigid rod slide bar 23 in the slot of horizontal plate 12 to provide a precise straight guide path for moving block 24, it ensures that the reciprocating motion of moving block 24 and connected rack 13 is stable and does not deviate. At the same time, the movable connection between moving block 24 and slide bar 23 can reduce frictional resistance, make the movement smoother, reduce vibration and noise, and avoid impact damage to parts.

[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
