Description

Technical Field

[0001] This utility model relates to sewing machines, and more particularly, to a sewing machine that is easy to maintain and clean. Background Technology

[0002] Currently, Chinese patent CN209907018U discloses a sewing machine, including a machine body with a heat dissipation component, which includes a cooling fan. The cooling fan draws air into the sewing machine to cool it down. The machine body also contains a motor and a transmission component. The transmission component usually needs to be lubricated to ensure the service life of the equipment.

[0003] The aforementioned patent still has shortcomings. When sewing fabrics in a sewing workshop, the fabric fibers are easily dispersed in the air. When the cooling fan draws air into the sewing machine, the fibers can easily become entangled on the motor shaft or transmission components, thus contaminating the lubricating oil and affecting operation. Existing sewing machines usually reduce the entry of fibers by installing a dust cover on the outside of the cooling fan. However, when the dust cover accumulates a lot of fibers, the heat dissipation function will decrease. At this time, regular maintenance and cleaning are required. The dust cover is usually fixed to the outside of the cooling fan with screws and other fasteners, which makes maintenance and cleaning quite troublesome. Utility Model Content

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered. Example

[0020] A sewing machine that is easy to maintain and clean includes a machine housing 1. A needle holder is provided at the head of the machine housing 1, and a cooling fan 21 is provided at the tail of the machine housing 1. A mounting frame 2 is provided on the outside of the machine housing 1. The mounting frame 2 is fixedly connected to the machine housing 1 by screws. A sliding slot 3 is provided in the mounting frame 2. A filter screen 4 is detachably installed in the sliding slot 3. The filter screen 4 slides and engages with the sliding slot 3. When the filter screen 4 is installed in the sliding slot 3, it blocks the air outlet of the cooling fan 21. When maintaining and cleaning the filter screen 4, it can be directly slid out or installed, making disassembly and installation more convenient and making it easier to clean fibers.

[0021] The mounting frame 2 is also equipped with a sliding slot 2 5. A partition 6 is provided between the sliding slot 2 and the sliding slot 1. A filter screen 2 7 is detachably installed in the sliding slot 2 5. The filter screen 2 7 slides and engages with the sliding slot 2 5. The sliding slot 1 3 and the sliding slot 2 5 have the same size and structure. The filter screen 2 7 has the same structural size as the filter screen 1 4. That is, the filter screen 1 4 can be accurately installed in the sliding slot 2 5. When it is necessary to clean the fibers, the filter screen 1 4 is cleaned first, then the filter screen 2 7 is pulled out and the filter screen 1 4 is inserted into the sliding slot 2 5. After cleaning the filter screen 2 7, it is inserted back into the sliding slot 1 3. Thus, the filter screen can be cleaned without stopping the equipment, and the amount of fibers entering the machine casing 1 is reduced, increasing production efficiency.

[0022] The top side of the mounting frame 2 is also provided with a side plate 8, which has a mounting hole 9 and a through hole 10. The partition plate 6 has a mounting hole 11. Mounting holes 9 and 11 are through holes, and each hole is provided with a spring 12, a steel ball 13, and an adjusting post 14. Mounting holes 9 and 11 are staggered vertically, and the mounting hole 11 is coaxial with the partition plate 6 to facilitate the installation of springs 12 and steel balls 13. The adjusting post 14 is threaded to mounting holes 9 and 11. The filter screens 4 and 7 have two limiting grooves 15, which correspond to mounting holes 9 and 10 respectively. When the filter screen 14 and filter screen 27 are inserted into the sliding slot 13 and sliding slot 25, the steel ball 13 compresses the spring 12 and retracts into the mounting hole 19 and mounting hole 21. When the filter screen 14 and filter screen 27 are installed in place, the elastic energy stored in the spring 12 is released and presses against the steel ball 13, causing the steel ball 13 to press into the limiting groove 15. This reduces the vibration caused by the sewing machine during operation, which can lead to abnormal noise from the filter screen. Through the threaded connection between the adjusting column 14 and the mounting hole, the pressure of the steel ball 13 pressing against the limiting groove 15 can be controlled, making it easy to adjust the force required to pull out the filter screen.

[0023] Filter screen 14 includes a mesh 16 and an outer frame 17. The outer frame 17 wraps around the outside of the mesh 16 and is slidably disposed in the sliding slot 13. A limiting groove 15 is formed on the outer frame 17. A handle 18 is also provided on the top of the outer frame 17. Filter screen 27 has the same structure as filter screen 14. A rubber plate 19 is also provided on the inner side wall of the bottom of the sliding slot 13 and the sliding slot 25. When filter screen 14 and filter screen 27 are inserted into the sliding slot 13 and the sliding slot 25, the rubber plate 19 is compressed, further limiting the vibration of the filter screen and preventing the filter screen from making abnormal noise.

[0024] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
