Description

Technical Field

[0001] The utility model relates to the technical field of air jet looms, in particular to a lubricating oil cooling structure for air jet looms. Background Art

[0002] The temperature of the lubricating oil of the jet loom should not be too high during operation. If the temperature is too high, the machine will stop and alarm. Currently, the commonly used cooling method is to use a hair dryer to cool it down. However, in summer, the temperature of the lubricating oil will rise and exceed 75°C. The heat dissipation effect is not ideal, affecting production.

[0003] In view of the above problems, it is necessary to improve the existing cooling method. Utility Model Content

[0004] In order to solve the above technical deficiencies, the utility model provides a lubricating oil cooling structure for an air jet loom, which can effectively cool the lubricating oil.

[0005] The utility model discloses a lubricating oil cooling structure for an air jet loom, comprising an air jet loom frame, wherein two groups of warp threads are transported between the frames on both sides, an air jet nozzle is arranged on the frame on one side, a flat box is horizontally arranged below the two groups of warp threads, the position of the flat box corresponds to the position of the air jet nozzle, two ends of the flat box are fixed to the frame, a water absorption layer is laid on the upper end surface of the flat box, a tap water pipe is arranged above the water absorption layer, a valve is arranged on the tap water pipe, an oil tank is arranged below the flat box, an oil inlet pipe is arranged at one end of the lower side of the flat box, an oil outlet pipe is arranged at the other end of the lower side of the flat box, an oil pump is arranged on the oil inlet pipe, the lower end of the oil inlet pipe is communicated with the bottom of the oil tank, the lower end of the oil outlet pipe is communicated with the oil tank, and a lubrication circulation system of the air jet loom is connected with the oil tank.

[0006] When the above scheme is in use, the lubricating oil after lubricating the jet loom by the lubrication circulation system flows into the oil tank, and the lubricating oil entering the oil tank is then pumped into the flat box through the oil pump. The lubricating oil entering the flat box flows from the side of the oil inlet pipe to the side of the oil outlet pipe. At the same time, the valve on the tap water pipe is opened, and the opening amplitude can make the tap water drip on the water absorption layer at a certain frequency. The tap water penetrates the water absorption layer. During the weaving process of the warp, the weft is ejected through the air nozzle. The high-speed gas ejected from the air nozzle makes the air on the upper side of the flat box flow rapidly, thereby accelerating the evaporation of water on the water absorption layer. The rapid evaporation of water can bring a lot of heat, so that the lubricating oil flowing in the flat box is cooled, and the cooled lubricating oil flows into the oil tank to lubricate the jet loom again through the lubrication circulation system.

[0007] Preferably, the water outlet of the tap water pipe is arranged on the side above the water absorbing layer close to the air jet nozzle. Such a design makes the penetration direction of the tap water consistent with the direction of the airflow ejected from the air jet nozzle, making it easier for the tap water to penetrate the water absorbing layer.

[0008] The utility model provides a lubricating oil cooling structure for an air jet loom, which has the beneficial effect of utilizing the airflow sprayed from the air jet nozzle to accelerate the evaporation of water on the water absorption layer, thereby taking away the heat of the lubricating oil flowing in the flat box body, thereby achieving effective cooling of the lubricating oil.

[0010] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0011] Embodiment 1:

[0012] like Figure 1 As shown, the utility model discloses a lubricating oil cooling structure for an air jet loom, comprising an air jet loom frame 1, two groups of upper and lower warp threads 7 are transported between the frames 1 on both sides, an air jet nozzle 10 is arranged on the frame 1 on one side, a flat box 5 is horizontally arranged below the two groups of warp threads 7, the position of the flat box 5 corresponds to the position of the air jet nozzle 10, both ends of the flat box 5 are fixed to the frame 1, a water absorption layer 6 is laid on the upper end surface of the flat box 5, a tap water pipe 9 is arranged above the water absorption layer 6, a valve 11 is arranged on the tap water pipe 9, an oil tank 3 is arranged below the flat box 5, an oil inlet pipe 2 is arranged at one end of the lower side of the flat box 5, an oil outlet pipe 4 is arranged at the other end of the lower side of the flat box 5, an oil pump 8 is arranged on the oil inlet pipe 2, and the lower end of the oil inlet pipe 2 is connected to the bottom of the oil tank 3, the lower end of the oil outlet pipe 4 is connected to the oil tank 3, and the lubrication circulation system of the air jet loom is connected to the oil tank 3.

[0013] When the above scheme is in use, the lubricating oil after lubricating the jet loom by the lubrication circulation system flows into the oil tank 3, and the lubricating oil entering the oil tank 3 is pumped into the flat box 5 through the oil pump 8. The lubricating oil entering the flat box 5 flows from the side of the oil inlet pipe 2 to the side of the oil outlet pipe 4. At the same time, the valve 11 on the tap water pipe 9 is opened, and the opening amplitude can make the tap water drip on the water absorption layer 6 at a certain frequency. The tap water penetrates the water absorption layer 6. During the weaving process of the warp 7, the weft is sprayed out through the air nozzle 10. The high-speed gas sprayed by the air nozzle 10 makes the air on the upper side of the flat box 5 flow quickly, thereby accelerating the evaporation of water on the water absorption layer 6.
