Description

Technical Field

[0001] This utility model relates to the field of knitted hat production technology, specifically a cooling device for knitted hat production. Background Technology

[0002] Knitted hats are a type of comfortable clothing for keeping warm. They are usually produced by sewing machines. The sewing needles of a sewing machine generate a lot of heat during operation. After working for a long time, they will expand due to heat, which will affect the working efficiency of the sewing machine.

[0003] In the prior art, a patent application with application number CN201721326520.7, published by the China National Intellectual Property Administration, discloses a sewing machine needle cooling device, including an air nozzle, a cooling device body, a cooling device side cover, a speed control knob, a fixing device, and a fixing plate. Fixing posts are welded to both sides of the bottom of the fixing plate, and suction cups are installed at the bottom of the fixing posts. A slot is provided inside the fixing device, which cooperates with the fixing plate. A power cord is installed on one side of the fixing device, and the cooling device body is connected to one side of the fixing device. An air nozzle is connected to the lower part of one side of the cooling device body. A filter screen is installed inside the cooling device body, mounted on the middle side wall inside the cooling device body. This invention uses a motor to drive a fan blade to rotate, drawing in cool air from the outside into the air nozzle, and finally spraying the cooled air from the air nozzle onto the needle, thereby dissipating heat from the needle.

[0004] However, the current technology still uses the traditional method to install the fan blades and the motor drive shaft. The traditional method involves setting screw holes on both the fan blades and the drive shaft, and screwing screws into the screw holes to install the fan blades and the drive shaft. This method requires the use of a third-party tool - a screwdriver - when disassembling and assembling the fan blades and the motor drive shaft, which makes the disassembly and assembly of the fan blades inconvenient.

One end of the locking rod is movably inserted into the locking rod mounting groove, and the other end of the locking rod is movably inserted into the guide rail.

[0011] Preferably, an annular groove is formed on the inner wall of the clamp mounting groove, and an elastic ring is fitted and fixed on the surface of the clamp, with the elastic ring being movably inserted into the annular groove.

[0012] Preferably, a pull ring storage groove is formed on the surface of the fan blade, and a pull ring is rotatably connected to the surface of the lever, with the pull ring disposed in the pull ring storage groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model proposes a cooling device for knitted hat production. One end of a limiting rod is inserted into a limiting groove, and the other end is inserted into a limiting rod mounting groove. This limits the motor's drive shaft within a shaft groove on the fan blade surface. When disassembling the motor and fan blades, the limiting rod is fully retracted into the limiting rod mounting groove, and then withdrawn from the limiting groove, allowing the motor to quickly exit the shaft groove, thus completing the disassembly of the motor and fan blades. When installing the motor and fan blades, the limiting rod is manually pressed fully into the limiting rod mounting groove, and then the motor is inserted into the shaft groove. Once the limiting rod mounting groove and the limiting groove are aligned, one end of the limiting rod extends into the limiting groove, while the other end remains in the limiting rod mounting groove, completing the installation of the motor and fan blades. This makes the disassembly and assembly of the motor and fan blades more convenient, eliminating the need for third-party tools. Attached Figure Description

All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a cooling device for the production of knitted hats, comprising: a motor 1 and a fan blade 2, a shaft groove 3 is formed on the surface of the fan blade 2, the motor 1 is movably inserted into the shaft groove 3, a limit rod mounting groove 4 is formed on the surface of the motor 1, a limit groove 6 is formed on the inner wall of the shaft groove 3, one end of a limit rod 5 is movably inserted into the limit rod mounting groove 4, and the other end of the limit rod 5 is movably inserted into the limit groove 6.

[0024] In actual use, one end of the limiting rod 5 is inserted into the limiting groove 6, and the other end of the limiting rod 5 is inserted into the limiting rod mounting groove 4, thereby limiting the drive shaft of the motor 1 in the shaft groove 3 opened on the surface of the fan blade 2. When it is necessary to disassemble the motor 1 and the fan blade 2, the limiting rod 5 is fully retracted into the limiting rod mounting groove 4, and the limiting rod 5 is withdrawn from the limiting groove 6, so that the motor 1 can be quickly withdrawn from the shaft groove 3, completing the disassembly of the motor 1 and the fan blade 2. When it is necessary to install the motor 1 and the fan blade 2, the limiting rod 5 is manually pressed fully into the limiting rod mounting groove 4, and then the motor 1 is inserted into the shaft groove 3. When the limiting rod mounting groove 4 and the limiting groove 6 are aligned, one end of the limiting rod 5 extends into the limiting groove 6, and the other end of the limiting rod 5 stays in the limiting rod mounting groove 4, thus completing the installation between the motor 1 and the fan blade 2.

[0025] Example 2: Based on Example 1, in order to control the movement of the limit rod 5, a rod hole 8 is provided on the surface of the fan blade 2. The rod hole 8 is a circular hole structure. A push-pull rod 9 is movably inserted into the rod hole 8. The push-pull rod 9 is a circular rod structure. One end of the push-pull rod 9 extends into the limit groove 6 and is fixed with a push plate 7. The other end of the push-pull rod 9 extends out of the rod hole 8 and is fixed with a button 10. A spring 11 is provided in the limit rod mounting groove 4. One end of the spring 11 abuts against the surface of the limit rod 5, and the other end of the spring 11 abuts against the inner wall of the groove of the limit rod mounting groove 4.

[0026] When disassembling the motor 1 and fan blade 2, press button 10 downwards. Button 10 pushes the push rod 9 completely into the rod hole 8. The rod hole 8 pushes the push plate 7 to move in the same direction, and the push plate 7 can push the limit rod 5 out of the limit groove 6. When installing the motor 1 and fan blade 2, press the limit rod 5 completely into the limit rod mounting groove 4 by hand. The spring 11 is compressed. Then, insert the motor 1 into the shaft groove 3. When the limit rod mounting groove 4 is aligned with the limit groove 6, the spring 11 can push one end of the limit rod 5 into the limit groove 6 under its own elasticity.

[0027] Example 3: Based on Example 2, in order to replace the spring 11, a guide rail 12 is provided on the surface of the limiting rod 5, and a locking rod mounting groove 13 is provided on the surface of the fan blade 2. One end of the locking rod 14 is movably inserted into the locking rod mounting groove 13, and the other end of the locking rod 14 is movably inserted into the guide rail 12. An annular groove 17 is provided on the inner wall of the locking rod mounting groove 13. An elastic ring 18 is fitted and fixed on the surface of the locking rod 14 and is movably inserted into the annular groove 17. A pull ring storage groove 15 is provided on the surface of the fan blade 2, and a pull ring 16 is rotatably connected to the surface of the locking rod 14. The pull ring 16 is disposed in the pull ring storage groove 15.

[0028] When it is necessary to replace spring 11, after removing the drive shaft of motor 1 from the shaft groove 3, unscrew one end of pull ring 16 from pull ring receiving groove 15, then hook pull ring 16 and pull it outward. Pull ring 16 pulls the locking rod 14 out of locking rod mounting groove 13, and locking rod mounting groove 13 also exits from guide rail 12. Then, the limiting rod 5 can be completely pulled out of limiting rod mounting groove 4. After that, take out the old spring 11 from limiting rod mounting groove 4, put the new spring 11 into limiting rod mounting groove 4, put the limiting rod 5 back into limiting rod mounting groove 4 and align guide rail 12 with locking rod mounting groove 13. Then, insert locking rod 14 back into locking rod mounting groove 13 and insert locking rod 14 into guide rail 12. At this time, elastic ring 18 is inserted back into ring groove 17, limiting locking rod 14 in locking rod mounting groove 13, and the replacement of spring 11 is completed.

[0029] In actual use, one end of the limiting rod 5 is inserted into the limiting groove 6, and the other end is inserted into the limiting rod mounting groove 4, thereby limiting the drive shaft of the motor 1 in the shaft groove 3 opened on the surface of the fan blade 2. When it is necessary to disassemble the motor 1 and the fan blade 2, the limiting rod 5 is fully retracted into the limiting rod mounting groove 4, and the limiting rod 5 is withdrawn from the limiting groove 6, so that the motor 1 can be quickly withdrawn from the shaft groove 3, completing the disassembly of the motor 1 and the fan blade 2. When it is necessary to install the motor 1 and the fan blade 2, the limiting rod 5 is manually pressed fully into the limiting rod mounting groove 4. Install the motor 1 in the mounting slot 4, then insert the motor 1 into the shaft slot 3. When the limiting rod mounting slot 4 is aligned with the limiting slot 6, one end of the limiting rod 5 extends into the limiting slot 6, and the other end of the limiting rod 5 remains in the limiting rod mounting slot 4, thus completing the installation between the motor 1 and the fan blade 2. When disassembling the motor 1 and the fan blade 2, press the button 10 downwards. The button 10 pushes the push rod 9 completely into the rod hole 8. The rod hole 8 pushes the push plate 7 to move in the same direction, and the push plate 7 pushes the limiting rod 5 out of the limiting slot 6. When installing the motor 1 and the fan blade 2, use your hand to... When the limiting rod 5 is fully pressed into the limiting rod mounting groove 4, the spring 11 is compressed. Then, the motor 1 is inserted into the shaft groove 3. When the limiting rod mounting groove 4 is aligned with the limiting groove 6, the spring 11, under its own elasticity, can push one end of the limiting rod 5 into the limiting groove 6. When the spring 11 needs to be replaced, after removing the drive shaft of the motor 1 from the shaft groove 3, unscrew one end of the pull ring 16 from the pull ring receiving groove 15, and then hook the pull ring 16 and pull it outward. The pull ring 16 pulls the locking rod 14 out of the locking rod mounting groove 13, and the locking rod mounting groove 13 also comes out from the groove. Remove the spring 11 from the guide rail 12, then pull the limit rod 5 completely out of the limit rod mounting slot 4. Next, remove the old spring 11 from the limit rod mounting slot 4, put the new spring 11 into the limit rod mounting slot 4, re-insert the limit rod 5 into the limit rod mounting slot 4, and align the guide rail 12 with the locking rod mounting slot 13. Then, insert the locking rod 14 back into the locking rod mounting slot 13 and insert the locking rod 14 into the guide rail 12. At this time, the elastic ring 18 is inserted back into the ring groove 17, limiting the locking rod 14 in the locking rod mounting slot 13, thus completing the replacement of the spring 11.
