Description

Technical Field

[0001] This application relates to the field of computerized flat knitting machine technology, specifically to a needle bed for a computerized flat knitting machine. Background Technology

[0002] The needle bed mount of a computerized flat knitting machine is an important component of the machine, used to support and fix the needle bed. The needle bed mount is usually made of sturdy metal materials, with a certain load-bearing capacity and stability to ensure that the needle bed remains level and stable during operation.

[0003] A search of utility model publication CN219410098U reveals a needle bed for a computerized flat knitting machine. The needle bed has several guide rail seats on both sides, with guide rails mounted on them. A transition piece connects the needle bed between the guide rail seats on one side, and an oil collection groove is formed on the transition piece. The needle bed, guide rail seats, and transition piece are integrally cast. This utility model's needle bed, by integrally casting the oil collection groove, guide rail seats, and needle bed, enhances the overall rigidity of the needle bed, ensures the corresponding processing characteristics of the guide rail seats and the needle bed mounting surface, and improves production efficiency and yield. Simultaneously, it overcomes the problem of oil leakage from the needle bed, reducing environmental pollution, increases the contact area between the needle bed and the needle bed mounting surface, and improves the stability of the needle bed.

[0004] The aforementioned application enhances the overall rigidity of the needle bed by integrally casting the oil collection groove and the needle bed itself. However, with the aforementioned needle bed, the lubricating oil collected in the oil collection groove is discharged through oil pipes. Since the lubricating oil often contains substances such as fibers, the oil passages are very easy to become clogged, and the oil passages on the needle bed still need to be disassembled and maintained regularly. In response, a computerized flat knitting machine needle bed is proposed to solve the aforementioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a needle bed for a computerized flat knitting machine, which has the advantages of providing a pull-out oil trough with sensors for periodic oil drainage, reducing the likelihood of oil circuit blockage.

[0006] To achieve the above objectives, this application provides the following technical solution: a needle bed for a computerized flat knitting machine, comprising a needle bed, an integrally connected guide rail frame on the side of the needle bed, a guide rail mounted on the guide rail frame, an oil rail fixedly mounted at the bottom of the needle bed, an oil pan slidably mounted inside the oil rail, oil collection grooves spaced apart between the guide rail frames, and adjacent oil collection grooves interconnected, with an oil leakage hole connecting the oil collection grooves and the oil rail;

[0007] The bottom of the oil pan is also fixedly connected to a base, and a seal is fixedly connected to the base. The oil pan is also equipped with a sensor structure for sensing lubricating oil.

[0008] Furthermore, the oil leakage hole is a wide-mouth hole, and the wide-mouth surface faces upwards from the oil collection groove.

[0009] Furthermore, the inner cavity of the oil pan has an integrally protruding cylindrical protrusion facing upwards, and the sensor structure includes an infrared transceiver fixedly mounted on the base and a sensing disk located within the protrusion.

[0010] Furthermore, a float tube is fixedly installed on the inner wall of the oil pan, a float is slidably installed inside the float tube, and a connecting rod connects the float tube and the protrusion.

[0011] Furthermore, a pressure plate that is slidably connected to the float tube is vertically fixed to one end of the connecting rod, and a bracket that is fixedly connected to the induction plate is vertically fixed to the other end of the connecting rod.

[0012] Furthermore, a mounting bracket is fixedly installed at the lower end of the float tube, an air hole for balancing the air pressure inside the float tube is opened on the upper side of the float tube, and a guide strip is fixedly installed on the inner wall of the float tube.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] This computerized flat knitting machine needle bed replaces the traditional hydraulic oil delivery method with an oil rail and oil pan below the needle bed. This method reduces the possibility of oil pipe blockage caused by fibers in the lubricating oil. At the same time, an infrared transceiver and a sensor plate that do not come into contact with the lubricating oil are installed in the oil pan, which can indicate the lubricating oil level to the user, reduce maintenance, and improve the practicality of the device.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Please see Figures 1 to 4 The needle bed of a computerized flat knitting machine in this embodiment includes a needle bed 1, a guide rail frame 2 integrally connected to the side of the needle bed 1, a guide rail 3 installed on the guide rail frame 2, and an oil rail 5 fixedly installed at the bottom of the needle bed 1. An oil pan 6 is slidably installed in the oil rail 5 for collecting lubricating oil on the needle bed 1.

[0022] In this embodiment, oil collection grooves 4 are spaced apart between the guide rail frames 2, and adjacent oil collection grooves 4 are interconnected. There is an oil leakage hole 7 connecting the oil collection grooves 4 and the oil rail 5.

[0023] Preferably, the oil leakage hole 7 is a wide-mouth hole, and the wide-mouth surface faces upwards of the oil collection groove 4, in order to reduce the blockage of the oil leakage hole 7 by lubricating oil containing fibers.

[0024] It should be noted that an oil pan 6 for collecting lubricating oil is slidably installed inside the oil rail 5. A sealing strip that fits into the oil rail 5 is also fixedly installed on the side of the oil pan 6 to stabilize the sliding position of the oil pan 6 inside the oil rail 5.

[0025] In this embodiment, the oil pan 6 is a rectangular structure with an opening at the top. The bottom of the oil pan 6 is also fixedly connected to a base 61, and the seal is fixedly connected to the base 61. The oil pan 6 is also equipped with a sensor structure for sensing lubricating oil.

[0026] It should be noted that the inner cavity of the oil pan 6 has an integral cylindrical protrusion 62 facing upwards. The sensor structure includes an infrared transceiver 14 fixedly mounted on the base 61 and a sensing disk 13 located in the protrusion 62.

[0027] In practice, the position of the sensing disk 13 within the book search protrusion 62 is sensed by the infrared transceiver 14, thereby determining the level of lubricating oil in the oil pan 6.

[0028] In this embodiment, a float tube 8 is also fixedly installed on the inner wall of the oil pan 6, a float 11 is slidably installed inside the float tube 8, and a connecting rod 9 connects the float tube 8 and the protrusion 62.

[0029] Specifically, a pressure plate 10 that is slidably connected to the float tube 8 is vertically fixed to one end of the connecting rod 9, and a bracket 12 that is fixedly connected to the induction plate 13 is vertically fixed to the other end of the connecting rod 9.

[0030] This design allows the pressure plate 10 to move vertically in sync with the induction plate 13. The float ball 11 can lift the pressure plate 10 to adjust the height of the induction plate 13, thereby synchronously reflecting the level of the lubricating oil.

[0031] In this embodiment, a mounting bracket 81 is also fixedly installed at the lower end of the float tube 8. The mounting bracket 81 is a suspended bracket used to expose the lower opening of the float tube 8 so that the collected oil can rise inside the float tube 8.

[0032] Preferably, an air hole 83 is provided on the upper side of the float tube 8 to balance the air pressure inside the float tube 8. The air hole 83 can make the hydraulic oil level in the float tube 8 and the liquid level in the oil pan 6 the same.

[0033] Understandably, a guide bar 82 is also fixedly installed on the inner wall of the float tube 8 to limit the rising trajectory of the float 11 and improve the lifting stability of the float 11.

[0034] The working principle of the above embodiments is as follows:

[0035] The lubricating oil collected at the oil collection groove 4 on the needle bed 1 is collected into the oil pan 6 on the oil rail 5 through the oil leakage hole 7. As the amount of lubricating oil in the oil pan 6 increases, the liquid level rises. At this time, the float 11 in the float tube 8 rises with the liquid level of the lubricating oil. The rise of the float 11 lifts the pressure plate 10. The connecting rod 9 connected to the pressure plate 10 drives the sensing plate 13 to rise in height in sync. The infrared transceiver 14 located below the sensing plate 13 senses the change value, thereby knowing the amount of lubricating oil collected. When the liquid level limit is reached, the user can manually pull out the oil pan 6 to clean the lubricating oil, thereby avoiding the phenomenon of oil pipe blockage.
