DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] It should be noted that in this embodiment, the directions or positional relationships indicated by "upper," "lower," "front," and "back" are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this application and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed, or operate in a specific direction. Therefore, they should not be construed as limitations on this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0037] like Figure 1 and Figure 2 As shown, in this embodiment, a lubricating and cooling device for a shuttle assembly is provided. The device includes a shuttle bed 1, a shuttle 20, and an air supply mechanism. The shuttle bed 1 has a cavity, which is a cavity structure. An air storage chamber 15 is opened on the shuttle bed 1 at the periphery of the cavity. An air blowing hole 16 is provided on the shuttle bed 1 to connect the cavity and the air storage chamber 15. The air storage chamber 15 is provided with cooling gas at a certain pressure that can be stored or continuously introduced. The cooling gas can be delivered into the cavity through the air blowing hole 16 to deliver cooling air.

[0038] The shuttle 20 is arranged in the cavity. When the shuttle assembly is working, the shuttle 20 can swing back and forth in the cavity. There is an area on the inner wall of the cavity that is in sliding contact with the outer periphery of the shuttle 20. In other words, when the shuttle 20 swings, the outer periphery of the shuttle 20 reciprocates within a certain area on the inner wall of the cavity. The end of the blowing hole 16 away from the air storage cavity 15 is distributed in the above area. Please refer to Figure 6 As a result, the cooling gas in the air storage chamber 15 can directly act on the position of the area, thereby directly cooling the contact surface between the shuttle 20 and the shuttle bed 1.

[0039] The air supply mechanism is located outside the shuttle bed 1 and can be connected to the air storage chamber 15, thereby continuously providing the air storage chamber 15 with cooling gas with a preset pressure. Since the cooling gas has a certain pressure, the cooling gas has a certain flow speed when blowing toward the contact surface between the shuttle 20 and the shuttle bed 1, which can improve the cooling efficiency of the contact surface between the shuttle 20 and the shuttle bed 1.

[0040] In summary of the above embodiments, the present application opens an air storage chamber 15 on the shuttle bed 1, and the air storage chamber 15 contains sufficient or continuous cooling gas. The cooling gas in the air storage chamber 15 can be blown toward the contact surface between the shuttle bed 1 and the shuttle 20 through the blowing hole 16, and one end of the blowing hole 16 blowing toward the contact surface is distributed in the sliding contact area between the shuttle 20 and the shuttle bed 1, which can ensure the cooling effect of the entire sliding contact area, avoid the shuttle 20 from being burned and blackened due to frictional heat, and ensure the working efficiency of the shuttle 20.

[0041] In some embodiments, a lubricating oil chamber 13 is further provided on the shuttle bed 1 at the periphery of the cavity. Figure 4 and Figure 5 The lubricating oil chamber 13 is used to store a certain amount of lubricating oil. An oil outlet 14 is provided on the shuttle bed 1 to connect the accommodating chamber and the lubricating oil chamber 13, and the end of the oil outlet 14 away from the lubricating oil chamber 13 is also distributed in the above-mentioned area; the lubricating oil can enter the contact surface between the shuttle bed 1 and the shuttle 20 through the oil outlet 14, so that the above-mentioned area can be fully lubricated, thereby ensuring the lubrication effect of the shuttle 20 and avoiding the shuttle 20 from heating up due to insufficient lubricating oil.

[0042] On this basis, the device further includes an oil supply mechanism, which is located outside the shuttle bed 1 and can be communicated with the lubricating oil chamber 13 to provide the lubricating oil chamber 13 with sufficient lubricating oil.

[0043] In addition, since the above-mentioned area has a certain length in the circumferential direction of the shuttle 20, in order to ensure that the area and the shuttle 20 can be fully cooled, the air storage chamber 15 can also be set to extend and distribute along the circumference of the cavity, that is, the air storage chamber 15 has a certain length in the circumferential direction of the cavity, and the air storage chamber 15 and the cavity are respectively connected through multiple blowing holes 16, and the multiple blowing holes 16 are distributed in the above-mentioned area along the circumference of the shuttle 20, so that the cooling gas acts on the above-mentioned area and the outer periphery of the shuttle 20 in a wider range, which can further ensure the overall cooling effect of the shuttle 20.

[0044] In addition, since the air storage chamber 15 itself can store a certain amount of cooling gas, the cavity where the air storage chamber 15 is located also has a certain cooling effect, which can play a role in cooling the shuttle bed 1 to a certain extent. Figure 5 , and the air storage chambers 15 distributed along the circumference of the cavity can cool the shuttle bed 1 on the periphery of the cavity in the circumferential direction, and can play a certain cooling role inside the cavity.

[0045] For further information, please refer to Figure 5An air inlet passage 18 communicating with the air storage chamber 15 and an oil inlet passage 17 communicating with the lubricating oil chamber 13 are provided on the shuttle bed 1. An air pipe joint 3 is externally connected to the air inlet passage 18 at one end facing away from the air storage chamber 15. An air supply mechanism is connected to the air inlet passage 18 via the air pipe joint 3, thereby providing cooling air to the air storage chamber 15. An oil pipe joint 2 is externally connected to the oil inlet passage 17 at one end facing away from the lubricating oil chamber 13. An oil supply mechanism is connected to the oil inlet passage 17 via the oil pipe joint 2, thereby providing lubricating oil to the lubricating oil chamber 13.

[0046] Please refer to Figure 1 The oil supply mechanism includes an oil reservoir 6, an oil pipe 4, and a regulating valve 5. The oil reservoir 6, serving as an oil storage device, stores a sufficient amount of lubricating oil under a certain pressure. The oil reservoir 6 and the oil pipe 4 are in sealed communication, allowing the lubricating oil in the oil reservoir 6 to be discharged through the oil pipe 4. The oil pipe 4 connects the oil pipe connector 2 and the oil reservoir 6, thereby directing the lubricating oil into the lubricating oil chamber 13. The regulating valve 5 is disposed on the oil pipe 4. By adjusting the opening of the regulating valve 5, the flow rate of the lubricating oil in the oil pipe 4 is adjusted, thereby controlling the amount of lubricating oil in the lubricating oil chamber 13.

[0047] It should be noted that the conventional oil circuit design usually provides lubricating oil to the sliding area of ​​the shuttle 20 through only one lubricating oil chamber 13, which will lead to the problem that the oil amount is difficult to control and the local lubrication effect is poor; however, the present application sets two lubricating oil chambers 13, please refer to Figure 2 The two lubricating oil chambers 13 are distributed on both sides of the shuttle 20, or in other words, the two lubricating oil chambers 13 are distributed on both sides of the swing area of ​​the shuttle 20. The oil pipe joint 2 is connected to the lubricating oil chambers 13 one-to-one through the oil pipe 4, and each oil pipe 4 is provided with a regulating valve 5, thereby realizing independent control of the oil amount in the two lubricating oil chambers 13, ensuring the control accuracy of the lubricating oil, and avoiding the problem of poor local lubrication effect of the shuttle 20.

[0048] Please refer to Figure 1 The gas supply mechanism includes an air source processing component 11, an electromagnetic valve 10 and a vortex cooler 9. The air source processing component 11 is the main component for providing the air source, which can compress the air and provide gas that meets the air pressure requirements. The electromagnetic valve 10 is connected to the outlet of the air source processing component 11 through the air pipe 8. The electromagnetic valve 10 can be used to adjust the amount of air passing through the air pipe 8, thereby adjusting the required amount of air according to actual needs. The inlet of the vortex cooler 9 is connected to the outlet of the electromagnetic valve 10, and the outlet of the vortex cooler 9 is connected to the air pipe 8 and the air pipe joint 3. After the gas passes through the vortex cooler 9, the vortex cooler 9 can cool the gas, thereby discharging the cooling gas at the outlet of the vortex cooler 9, and the cooling gas is passed into the gas storage chamber 15 through the air pipe 8.

[0049] Furthermore, in order to improve the cooling effect of the cooling gas on the contact surface between the shuttle 20 and the shuttle bed 1, the number of the air storage chambers 15 can be set to two, and the two air storage chambers 15 are distributed on both sides of the shuttle 20, or in other words, the two air storage chambers 15 are distributed on both sides of the swing area of ​​the shuttle 20, please refer to Figure 2 Therefore, the shuttle 20 can be cooled by the cooling gas to any side it swings to.

[0050] On this basis, the two air pipe joints 3 are connected to the air storage chambers 15 in a one-to-one correspondence, and the two air pipe joints 3 can be connected to the outlet of the vortex refrigerator 9 through the tee 7.

[0051] The device also includes a control system 12, see Figure 1 The control system 12 is electrically connected to the solenoid valve 10. The control system 12 can be operated through a human-computer interaction interface to control the driving current, power-on frequency and power-on duration of the solenoid valve 10, thereby selecting different control methods according to different working conditions, or writing the control program into the programmable control unit built into the control system 12 to realize automatic control of the solenoid valve 10.

[0052] In addition, in order to facilitate the maintenance of the air storage chamber 15 and the lubricating oil chamber 13 and ensure the efficiency of gas and oil discharge, an opening side can be set on the air storage chamber 15 and the lubricating oil chamber 13, a sealing strip 19 is set on the opening side of the air storage chamber 15, and a sealing plug is set on the opening side of the lubricating oil chamber 13. Please refer to Figure 3 During normal operation, the sealing strip 19 seals against the opening of the air storage chamber 15 and ensures that the air storage chamber 15 is stably sealed. When maintenance of the air storage chamber 15 is required, the sealing strip 19 can be removed for easy maintenance. Similarly, the effect of the sealing plug can be referred to the sealing strip 19 and will not be described in detail here.

[0053] The present application also provides a sewing device, which may be a bartacking machine, etc. The sewing device includes the above-mentioned shuttle assembly lubrication and cooling device.

[0054] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

The description of the above examples is only intended to help understand the method and core ideas of this application. It should be noted that for those skilled in the art, without departing from the principles of this application, various improvements and modifications can be made to this application, and such improvements and modifications also fall within the scope of protection of the claims of this application.
