Description

Technical Field

[0002] Warp knitting involves knitting a fabric by feeding one or more parallel yarns onto all the needles of the machine in the warp direction, forming loops simultaneously.

However, the current warp knitting machines have a short width, and the load, torque, and friction of the drawing box are small. Soaking the worm gear in a closed and viscous oil, that is, in the drawing box, will not cause the drawing box temperature to be too high.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] Specific examples are given below.

[0028] See also Figure 1-Figure 5 The present invention provides a lubricating device for a pulling box capable of cooling, comprising a box body 1; a drainage pipe 2 is fixedly mounted on the inner top wall of the box body 1; a discharge pipe 3 is connected and mounted on one side of the box body 1; an exhaust pipe 4 is connected and mounted adjacent to the discharge pipe 3 on the box body 1; and a water inlet pipe 5 is connected and mounted on the top of the box body 1;

[0029] An auxiliary mechanism 6 is provided in the box body 1, and the auxiliary mechanism 6 includes a support block 61 fixedly mounted on the inner side wall of the box body 1, a driving rod 62 is fixedly mounted on the top of the support block 61, one end of the driving rod 62 is inserted into the drainage pipe 2, and a first fan blade 63 is fixedly mounted on the outer wall of the driving rod 62 located in the exhaust pipe 4, a first gear 64 is fixedly mounted on the outer wall of the driving rod 62, a transmission rod 65 is rotatably mounted on the inner bottom wall of the box body 1, a stirring rod 66 is fixedly mounted on the outer wall of the transmission rod 65, and a second gear 67 is fixedly mounted on the outer wall of the transmission rod 65, and the first gear 64 is meshed with the second gear 67;

[0030] In order to achieve the effect of circulating the lubricating oil in the box body and taking away the heat, thereby reducing the overall temperature of the pulling box, the lubricating oil is injected into the box body 1 through the oil filling hole on the box body 1 in conjunction with the drainage pipe 2 through the setting of the auxiliary mechanism 6. The box body 1 is a pulling box, that is, as the lubricating oil is pumped in, the lubricating oil impacts the multiple first blades 63 and drives the multiple first blades 63 distributed in an annular manner and equidistantly to drive the driving rod 62 to rotate, and at the same time drives the first gear 64 to rotate, and the first gear 64 is engaged with the second gear 67, and then the second gear 67 is driven to rotate by the first gear 64, so that the transmission rod 65 rotates, and then the transmission rod 65 drives the multiple stirring rods 66 installed thereon to rotate, stirring the lubricating oil in the box body 1, so that the newly entered low-temperature lubricating oil is neutralized with the high-temperature lubricating oil in the box body 1 to reduce the temperature of the pulling box, and avoid due to The temperature of the drawing box is too high and a safety accident occurs. At the same time, after the lubricating oil accumulates to a certain height in the box 1, the lubricating oil can flow out of the box 1 through the oil drain port and the discharge pipe 3 opened on the box 1 under high pressure in the drawing box, and cooperate with the external cooling equipment, i.e., the condenser, to cool the lubricating oil flowing out of the box 1 and then re-inject it into the box 1 through the drainage pipe 2, thereby allowing the lubricating oil in the box 1 to circulate and take away the heat, thereby reducing the overall temperature of the drawing box. The exhaust pipe 4 is set to ensure the discharge of the gas in the box 1, and then ensure that the lubricating oil can be stably discharged from the discharge pipe 3, thereby solving the problem that after the width of the warp knitting machine is lengthened, the cloth drawing density is low, resulting in increased friction between the worm wheel 17 and worm 16, increased heat, and the breathable cap can only ventilate but not dissipate heat, resulting in the drawing box temperature being too high and posing a safety hazard.

[0031] Further, such as Figure 2 and Figure 3 As shown, a connecting block 7 is fixedly mounted on the inner side wall of the drainage tube 2, and a limiting ring 8 is sleeved on the outer wall of the driving rod 62 located inside the drainage tube 2. One end of the connecting block 7 is fixedly connected to the limiting ring 8, and the stirring rod 66 is tilted. During operation, the setting of the limiting ring 8 and the connecting block 7, in conjunction with the support block 61, ensures the stability of the driving rod 62 during operation, preventing the driving rod 62 from shaking due to the rotation of the multiple first blades 63, causing the first blades 63 to collide with the inner wall of the drainage tube 2, thereby ensuring the stability of the operation of the auxiliary mechanism 6. The tilted setting of the stirring rod 66 can generate a vortex when the lubricating oil is stirred and mixed, thereby better ensuring the mixing of high-temperature lubricating oil and low-temperature lubricating oil, and continuously neutralizing and cooling the lubricating oil.

[0032] Further, such as Figure 4 and Figure 5As shown, a sealing block 9 is slidably installed in the exhaust pipe 4, a connecting column is fixedly installed at one end of the sealing block 9, a plug-in block 10 is fixedly installed on one side of the outer wall of the connecting column, and the plug-in block 10 is inserted into a slot 11 opened on the inner wall of the exhaust pipe 4, and one end of the plug-in block 10 is elastically connected to the inner wall of the slot 11 through a spring 12. During operation, through the arrangement and cooperation of the sealing block 9, the connecting column, the plug-in block 10 and the spring 12, when the pulling box stops running or stops injecting lubricating oil into the box body 1, the exhaust pipe 4 can be sealed in time to prevent foreign matter from entering the box body 1 and mixing with the box body 1 and affecting the subsequent circulation of the lubricating oil. That is, in the process of the lubricating oil being pumped into the box body 1 through the drainage pipe 2, the lubricating oil squeezes out the air in the box body 1, and the squeezed air impacts the connecting column and the sealing block 9, and causes the sealing block 9 to move out of the exhaust pipe 4. The diameter of the connecting column is smaller than the sealing block 9, and it can pass through one side opening of the exhaust pipe 4, and create a gap between the one side opening of the exhaust pipe 4 and the connecting column, and then make The exhaust pipe 4 is used to exhaust the air in the box body 1. At the same time, the connecting column is limited in the exhaust pipe 4 by the plug-in block 10. When the injection of lubricating oil into the box body 1 is stopped, the air pressure in the box body 1 remains stable. At this time, the pressure of the air pressure on the plug-in block 10 is gradually less than the pressure of the spring 12 on the plug-in block 10, that is, under the pressure of the spring 12, the plug-in block 10 can drive the connecting column and the sealing block 9 to reset, so that the exhaust pipe 4 is closed. The outer wall of the sealing block 9 is provided with a sealing gasket, which ensures the sealing of the sealing block 9 when it is embedded in the exhaust pipe 4, and avoids foreign matter from entering the box body 1 and mixing with the box body 1 and the box body 1 when the traction box stops running or stops injecting lubricating oil into the box body 1.

[0033] Further, such as Figure 4 and Figure 5As shown, a filter ring 13 is fixedly installed on the outer wall of the connecting column, a filter groove is opened on the filter ring 13, a filter net is fixedly installed on the inner wall of the filter groove, and a fixed block 14 is fixedly installed on the outer wall of the connecting column. The fixed blocks 14 are provided in two groups, and the two groups of fixed blocks 14 are symmetrically distributed relative to the filter ring 13. During operation, a filter ring 13 is installed on the outer wall of the connecting column, and the filter mesh on the filter ring 13 is matched. That is, when the lubricating oil is pumped into the box body 1 through the drainage pipe 2, the lubricating oil squeezes out the air in the box body 1, and the squeezed air impacts the connecting column and the sealing block 9, and causes the sealing block 9 to move out of the exhaust pipe 4. The diameter of the connecting column is smaller than the sealing block 9, and it can pass through one side opening of the exhaust pipe 4, and a gap is generated between the one side opening of the exhaust pipe 4 and the connecting column, thereby exhausting the exhaust pipe 4 to discharge the air in the box body 1. At the same time, the connecting column is limited in the exhaust pipe 4 by the plug-in block 10. When the injection of lubricating oil into the box body 1 is stopped, the air pressure in the box body 1 remains stable. At this time, the pressure of the air pressure on the plug-in block 10 is gradually less than that of the spring 1 Regarding the pressure of the plug-in block 10, that is, under the pressure of the spring 12, the plug-in block 10 can drive the connecting column and the sealing block 9 to reset, so that the exhaust pipe 4 is closed. The outer wall of the sealing block 9 is provided with a sealing gasket, which ensures the sealing performance of the sealing block 9 when it is embedded in the exhaust pipe 4, and prevents foreign matter from entering the box body 1 and mixing with the box body 1 when the pulling box stops running or the lubricating oil is stopped. It also prevents the sealing block 9 from being separated from the exhaust pipe 4 for a long time and causing it to get stuck, which causes the sealing block 9 to be unable to automatically reset when the pulling box stops running, causing dust and foreign matter to flow back into the box body 1. At the same time, the filter ring 13 is limited and positioned by the two fixing blocks 14, which prevents the filter ring 13 from being formed or displaced, thereby ensuring the filtering effect.

[0034] Further, such as Figure 3 and Figure 4 As shown, a positioning rod 15 is rotatably mounted on the inner side wall of the housing 1, and the other end of the positioning rod 15 is inserted into the exhaust pipe 4. A worm 16 is fixedly mounted on the outer wall of the positioning rod 15, and a worm gear 17 is fixedly mounted on the outer wall of the transmission rod 65. The worm gear 17 is meshed with the worm 16, and the second blade 18 is fixedly mounted on the outer wall of the positioning rod 15 located in the exhaust pipe 4. During operation, when the housing 1 is under high pressure and air is discharged through the exhaust pipe 4, the discharged air will impact the second blade 18, causing multiple second blades 18 to rotate and drive the positioning rod 15 to rotate. When the positioning rod 15 drives the worm 16 to rotate, the worm 16 cooperates with the worm gear 17, causing the worm gear 17 to rotate, and then synchronously drives the transmission rod 65 to rotate. The rotation of the transmission rod 65 synchronously drives multiple stirring rods 66 to rotate, thereby achieving stirring and mixing of the lubricating oil filled in the housing 1. While ensuring the stable discharge of air in the housing 1, the stirring and mixing of the lubricating oil can also be achieved.

[0035] Further, such as Figure 2 As shown, a limit rod 19 is fixedly mounted on the inner top wall of the housing 1, and a positioning ring 20 is sleeved on the outer wall of the positioning rod 15. The bottom end of the limit rod 19 is fixedly connected to the positioning ring 20. During operation, the arrangement and cooperation of the limit rod 19 and the positioning ring 20 facilitate support and positioning of the positioning rod 15, preventing deformation of the positioning rod 15 that would cause the second fan blade 18 to collide with the inner wall of the exhaust pipe 4, thereby ensuring the stability of the rotation of the second fan blade 18.

[0036] Further, such as Figure 1 As shown, the front of the box body 1 is provided with an observation port 21, a transparent block is installed in the observation port 21, and scale lines 22 are provided on the front of the box body 1. During operation, the observation port 21 on the front of the box body 1 and the transparent block installed in the observation port 21 facilitate the operation of each structure in the box body 1 and the injection of lubricating oil at any time to facilitate adjustment and maintenance. The scale lines 22 on the front of the box body 1 facilitate more accurate observation of the level of lubricating oil in the box body 1.

[0037] Further, such as Figure 1 As shown, one end of the water inlet pipe 5 is connected to a three-joint connector via a connecting pipe, and a throttle valve is installed on the connecting pipe. During operation, the three-joint connector at one end of the water inlet pipe 5 is conveniently connected to an external oil manifold via the connecting pipe, ensuring a stable cooling circulation of the lubricating oil. The throttle valve installed on the connecting pipe facilitates the control of the injection speed of the lubricating oil through the throttle valve to prevent the lubricating oil from being filled up in the box body 1 due to excessive injection, which may cause the box body 1 to burst.

[0038] Working principle: The lubricating oil is injected into the box body 1 through the oil filling hole on the box body 1 and the drainage tube 2. The box body 1 is a pulling box, that is, as the lubricating oil is pumped in, the lubricating oil forms an impact on the multiple first blades 63 and drives the multiple first blades 63 to drive the driving rod 62 to rotate, and then the driving rod 62 rotates while driving the first gear 64 to rotate, and the first gear 64 and the second gear 67 rotate, and then the driving rod 62 drives the second gear 67 to rotate through the first gear 64, and then the second gear 67 drives the transmission rod 65 to rotate, and the transmission rod 65 drives the multiple stirring rods 66 installed thereon to rotate, stirring the lubricating oil in the box body 1, so that the newly entered low-temperature lubricating oil is neutralized with the high-temperature lubricating oil in the box body 1 to reduce pulling. The temperature of the box is controlled to avoid safety accidents caused by excessive temperature of the pulling box. When the air is discharged, it impacts the second fan blade 18, so that multiple fan blades drive the positioning rod 15 to rotate, and then the positioning rod 15 drives the worm 16 to rotate, and the worm 16 and the worm gear 17 rotate, and then the transmission rod 65 is assisted by the worm 16 and the worm gear 17 to drive the transmission rod 65 to rotate, and the transmission rod 65 is driven to rotate in conjunction with the lubricating oil injection box 1. At the same time, the second fan blade 18 can be driven to rotate through the transmission rod 65, thereby ensuring the stable discharge of air in the box 1, so that the first fan blade 63 and the second fan blade 18 are linked to the transmission rod 65 to operate. At the same time, after the lubricating oil accumulates to a certain height in the box 1, the lubricating oil can be discharged through the oil drain port opened on the box 1. The oil flows out of the box body 1 through the pipe 3, and the lubricating oil flowing out of the box body 1 is cooled by the external cooling equipment and then injected into the box body 1 again through the drainage pipe 2, so that the lubricating oil in the box body 1 circulates and takes away the heat, thereby reducing the overall temperature of the pulling box. The exhaust pipe 4 is set to ensure the discharge of the gas in the box body 1, thereby ensuring that the lubricating oil can be discharged stably from the exhaust pipe 3. At the same time, when the pulling box stops running or stops injecting lubricating oil into the box body 1, the exhaust pipe 4 can be blocked in time to prevent foreign debris from entering the box body 1 and mixing with the box body 1 and the box body 1, affecting the subsequent circulation of the lubricating oil, that is, in the process of pumping the lubricating oil into the box body 1 through the drainage pipe 2, the lubricating oil squeezes out the air in the box body 1. At the same time, the squeezed air impacts the connecting column and the sealing block 9, and causes the sealing block 9 to move out of the exhaust pipe 4. The diameter of the connecting column is smaller than the sealing block 9, and then leaks out of the exhaust port of the exhaust pipe 4, and then the air squeezed out of the box body 1 is discharged from the box body 1. At the same time, the connecting column is limited in the exhaust pipe 3 by the plug-in block 10. At the same time, when the lubricating oil is stopped from being injected into the box body 1, the plug-in block 10 drives the connecting column to reset under the elastic force of the spring 12, and then the connecting column drives the sealing block 9 to return to the exhaust pipe 3, and the outer wall of the sealing block 9 is provided with a sealing gasket, which ensures the sealing of the exhaust pipe 4 through the sealing block 9, and avoids foreign debris from entering the box body 1 and mixing with the box body 1 and the box body 1 when the traction box stops running or stops injecting lubricating oil into the box body 1.
