Description

Technical Field

[0001] The utility model relates to the technical field of warp knitting machine cooling, in particular to a cooling mechanism for a warp knitting machine. Background Art

[0002] Lubricating oil is a liquid lubricant used on various types of machinery to reduce friction, protect machinery and workpieces, and mainly plays roles such as lubrication, cooling, rust prevention, cleaning, sealing, and buffering. After the lubricating oil flows to the friction part, it will adhere to the friction surface to form an oil film, reducing the resistance between the friction machine parts, and the strength and toughness of the oil film are the key to exerting its lubricating effect.

[0003] For example, a Chinese patent with the application number CN202320927993.1 discloses a lubricating oil cooling device for a warp knitting machine, including an oil storage layer. A cooling layer is provided at the bottom of the oil storage layer. One end inside the oil storage layer is fixedly connected with a filter screen, and the filter screen is fixedly connected to the top of the cooling layer. A cooling grille is provided inside the cooling layer. A blade bracket is fixedly connected to the back of the cooling layer. A rotating shaft is rotatably connected in the middle of the blade bracket. The rotating shaft penetrates the blade bracket. One end of the rotating shaft is fixedly connected with a spiral wheel, and a rotating blade is fixedly connected to the outside of the spiral wheel. The other end of the rotating shaft is rotatably connected with a motor. Thus, the cooling grille conducts the heat inside the lubricating oil to the outside. Driven by the motor to control the rotation of the rotating shaft, the spiral wheel rotates, so that the rotating blade rotates, and exchanges the heat of the surrounding air outside the cooling grille to form an air cooling cycle, achieving the cooling of the lubricating oil, thereby improving the service life of the warp knitting machine. However, the problem that arises is that when the gas is pumped by the fan and passes through the cooling grille, dust will adhere to the cooling grille, affecting the heat dissipation effect of the cooling grille. Therefore, a filter screen is also added at the air inlet of some cooling mechanisms, but dust will also accumulate on the filter screen after long-term operation. Therefore, it is necessary for the staff to remove the filter screen from the cooling mechanism for regular cleaning, and the cleaning and maintenance process is cumbersome, time-consuming and laborious.

Specific embodiments

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts fall within the scope of protection of the present application.

[0023] According to Figure 1 、 2 As shown in 3, 4, 5, a cooling mechanism for a warp knitting machine is proposed in this embodiment, including a diversion frame 3 and a serpentine heat dissipation tube 9. The serpentine heat dissipation tube 9 is fixedly connected inside the diversion frame 3. An inlet 4 and an outlet 5 are provided outside the diversion frame 3, and the inlet 4 and the outlet 5 are communicated with the serpentine heat dissipation tube 9;

[0024] An air-cooled radiator is provided at the upper end of the diversion frame 3. The air-cooled radiator is placed above the serpentine heat dissipation pipe 9, and the radiator is detachably connected to the diversion frame 3; the detachable connection method facilitates the staff to replace the air-cooled radiator.

[0025] The lubricating oil in the warp knitting oil tank enters the serpentine heat dissipation pipe 9 through the liquid inlet 4, and then passes through the serpentine heat dissipation pipe 9 and is discharged from the liquid outlet 5 at the other end of the serpentine heat dissipation pipe 9. The serpentine heat dissipation pipe 9 conducts the internal heat of the lubricating oil to the outside. When the air-cooled radiator starts, a negative pressure is formed inside the diversion frame 3, and the air flow is drawn into the diversion frame 3 from below the diversion frame 3. When the air flow passes through the serpentine heat dissipation pipe 9, it will exchange the heat of the outside of the serpentine heat dissipation pipe 9 with the surrounding air, forming an air-cooled cycle to cool the lubricating oil.

[0026] A bottom frame 1 is provided at the lower end of the diversion frame 3. Open slots 2 are provided on two opposite sides of the bottom frame 1. A filter cloth 14 is provided below the serpentine heat dissipation pipe 9. Both ends of the filter cloth 14 pass through the two open slots 2, and a winding roller structure for winding and unwinding the filter cloth 14 is provided outside the bottom frame 1.

[0027] After the air enters the bottom frame 1 from below the bottom frame 1, it will pass through the filter cloth 14, and the filter cloth 14 will filter the dust in the air. When the dust on the filter cloth 14 accumulates, the winding roller structure will wind and unwind the filter cloth 14, roll up the filter cloth 14 full of dust, and release the filter cloth 14 without dust. The whole process does not require manual operation, and the cleaning and maintenance are convenient.

[0028] Regarding the winding roller structure:

[0029] The winding roller structure includes two winding shafts 12 and two winding shaft frames 17. The winding shaft frames 17 are fixedly connected to two opposite sides of the bottom frame 1. The winding shafts 12 are placed inside the winding shaft frames 17. Both ends of the winding shafts 12 are rotatably connected to the winding shaft frames 17. Both ends of the filter cloth 14 are respectively wound around the outside of the two winding shafts 12 and fixedly connected to the winding shafts 12. A transmission mechanism for controlling the two winding shafts 12 to rotate in the same direction is provided outside the open slot 2.

[0030] The winding method of the winding roller is that the transmission mechanism controls the two winding shafts 12 to rotate in the same direction. The winding shaft 12 on the left side of the bottom frame 1 rotates to roll up the filter cloth 14 under the serpentine heat dissipation pipe 9, and the winding shaft 12 on the right side of the bottom frame 1 rotates to release the filter cloth 14 wound on the outside to under the serpentine heat dissipation pipe 9 to ensure the smooth air flow inside and outside the filter cloth 14.

[0031] Specifically, the transmission mechanism includes a transmission shaft 16 provided outside the bottom frame 1. The transmission shaft 16 is rotatably connected to a rotating shaft bracket fixedly connected to the outside of the bottom frame 1. A worm 18 is provided at each end of the transmission shaft 16. The worm 18 is fixedly connected to the transmission shaft 16. The worm 18 meshes with a worm gear 15 provided outside the reel frame 17. The worm gear 15 is fixedly connected to the reel 12. A total driving member for controlling the rotation of the transmission shaft 16 is provided outside the bottom frame 1. The rotation of the reel 12 is driven by a worm and worm gear transmission, that is, the transmission shaft 16 drives the worm 18 to rotate. During the rotation of the worm 18, it meshes with the worm gear 15 to drive the worm gear 15 to rotate. Since the worm gear 15 is fixedly connected to the reel 12, the reel 12 will also rotate accordingly to wind and unwind the filter cloth 14 wound around its outside. The worm and worm gear transmission has self-locking property. When the transmission shaft 16 stops rotating, the worm gear 15 will not rotate back under the meshing of the nut surfaces between the worm gear 15 and the worm 18, and the stability of the reel 12 and the filter cloth 14 is better.

[0032] More specifically, the total driving member includes a motor 19, a first bevel gear 20 and a second bevel gear 21. The first bevel gear 20 is sleeved outside the transmission shaft 16 and fixedly connected to the transmission shaft 16. The mounting end of the motor 19 is fixedly connected to the outside of the bottom frame 1. The output end of the motor 19 is fixedly connected to the second bevel gear 21. The second bevel gear 21 meshes with the first bevel gear 20. The rotation of the transmission shaft 16 is driven by a bevel gear transmission, that is, the motor 19 drives the second bevel gear 21 to rotate. The second bevel gear 21 then drives the first bevel gear 20 to rotate through meshing with the first bevel gear 20. Since the first bevel gear 20 is fixedly connected to the transmission shaft 16, the first bevel gear 20 will also drive the transmission shaft 16 to rotate when it rotates.

[0033] In a preferred solution, the rotating shaft bracket is a rectangular cover body. The rectangular cover body is sleeved outside the transmission shaft 16, the first bevel gear 20 and the second bevel gear 21. The rectangular cover body is fixedly connected to the bottom frame 1. The two ends of the transmission shaft 16 pass through the two sides of the rectangular cover body, and the transmission shaft 16 is rotatably connected to the rectangular cover body. The advantage of such a setting is that in addition to supporting the rotation of the transmission shaft 16, the rotating shaft bracket can also protect the first bevel gear 20 and the second bevel gear 21, preventing external dust from falling into the mating part of the first bevel gear 20 and the second bevel gear 21 and affecting the operation of the total driving member.

[0034] Regarding the air-cooled radiator:

[0035] The air-cooled radiator includes an installation cover plate 6. There are two fans 7 provided at the upper end of the installation cover plate 6. The fans 7 are placed above the filter cloth 14. The fans 7 are fixedly connected to the installation cover plate 6. Multiple fixing bolts 8 are assembled at the corners of the installation cover plate 6. The fixing bolts 8 pass through the installation cover plate 6 and are threadedly connected to the bolt holes opened at the upper end of the diversion frame 3. When removing the fans 7 from the upper end of the diversion frame 3, just screw out the fixing bolts 8 at the corners of the installation cover plate 6 from the bolt holes at the upper end of the diversion frame 3. The detachable structural design makes disassembly, assembly and replacement convenient.

[0036] The working principle of this application:

[0037] The lubricating oil in the warp knitting oil tank enters the serpentine heat dissipation pipe 9 through the liquid inlet 4, and then discharges from the liquid outlet 5 at the other end of the serpentine heat dissipation pipe 9 after passing through the serpentine heat dissipation pipe 9. The serpentine heat dissipation pipe 9 conducts the internal heat of the lubricating oil to the outside. When the air-cooled radiator starts, a negative pressure is formed inside the diversion frame 3, and the air flow is drawn into the diversion frame 3 from below the bottom frame 1. When the air flow passes through the serpentine heat dissipation pipe 9, it will exchange the heat of the surrounding air outside the serpentine heat dissipation pipe 9 to form an air-cooled cycle to cool the lubricating oil. After the air enters the bottom frame 1 from below the bottom frame 1, it will pass through the filter cloth 14. The filter cloth 14 will filter the dust in the air. When the dust on the filter cloth 14 accumulates, the winding roller structure will wind and unwind the filter cloth 14, roll up the filter cloth 14 full of dust, and release the filter cloth 14 without dust. The whole process does not require manual operation, and the cleaning and maintenance are convenient.
