Description

Technical Field

[0001] This utility model relates to the field of garment production technology, and in particular to a suction device for a sewing machine used in garment production. Background Technology

[0002] In the production of clothing, sewing machines are used to sew fabrics together to complete the garment. Nowadays, sewing machines employ different sewing methods due to variations in garment design. One type, the flatbed sewing machine, uses a lockstitch formed by two threads (top and bottom) to sew two or more layers of fabric together. This sewing method is very common and suitable for sewing most fabrics and garment types.

[0003] However, during the garment production process, common sewing machines are prone to producing garment fragments and lint in the sewing area, causing blockage at the needle and affecting the sewing process. In view of this, we propose a suction device for sewing machines used in garment production. Utility Model Content

[0004] The purpose of this utility model is to address the problems existing in the background technology by proposing a suction device for a sewing machine used in garment production.

[0005] The technical solution of this utility model is as follows: A suction device for a sewing machine used in garment production includes a suction hood installed above the working area of ​​the sewing machine. The top opening of the suction hood is connected to a flow channel for facilitating suction. A suction fan for depressurizing the flow channel is symmetrically installed on the bottom wall of the flow channel. A rotatable blocking component is installed inside the suction hood. A cleaning component for cleaning the blocking component is arranged on the suction hood. A collection component for collecting debris is provided inside the flow channel.

[0006] Preferably, the blocking assembly includes a first filter screen, with rotating shafts symmetrically welded to the two side walls of the first filter screen, and rotating holes and rotating grooves symmetrically opened on the two side walls of the inner cavity of the suction hood, with one rotating shaft passing through the rotating hole and the other rotating shaft disposed in the rotating groove.

[0007] Preferably, one end of the rotating shaft is connected to a rotating head, a spring is connected to the side wall of the rotating head, and one end of each of the two springs is connected to a T-shaped insert.

[0008] Preferably, the side wall of the suction hood is symmetrically provided with positioning holes, and the rotating head is symmetrically provided with sliding holes. The locking ends of the two T-shaped inserts pass through the corresponding sliding holes and are inserted into the positioning holes.

[0009] Preferably, the cleaning component includes a support base on which a forward and reverse motor is mounted. The output end of the forward and reverse motor is connected to a threaded rod, and a cleaning brush is fitted on the outer ring surface of the threaded rod.

[0010] Preferably, a built-in groove is provided on one side wall of the inner cavity of the suction hood, and the cleaning brush is placed in the built-in groove when not in use.

[0011] Preferably, the collection component includes a storage box, a handle is welded to the outer wall of the storage box, and a second filter is installed in the bottom opening of the storage box.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] This invention uses a suction fan to depressurize the airflow channel, allowing the suction hood installed above the sewing machine's working area to adsorb debris and lint generated during operation. The blocking component prevents these debris from directly entering the storage box and affecting subsequent suction of the sewing machine's working area. After operation stops, pulling the T-shaped rod engages the limit switch on the first filter screen, flipping it to reverse the blocking face of the first filter screen. Releasing the T-shaped rod allows it to re-lock into the positioning hole on the outer wall of the suction hood under the elasticity of the spring, thus positioning the first filter screen after adjustment. This prevents the first filter screen from rotating during subsequent cleaning, which could cause debris to fall onto the sewing machine, requiring secondary cleaning. Activating the forward and reverse motor drives the threaded rod to move the cleaning brush, which sweeps away debris from the first filter screen. The suction fan then collects the debris into the storage box for processing, preventing clogging of the first filter screen and affecting its use. The cleaning process is simple and easy to operate.

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] Example

[0020] like Figure 1-3 As shown, this utility model proposes a suction device for a sewing machine used in garment production, including a suction hood 1 installed above the working area of ​​the sewing machine to facilitate the adsorption and cleaning of debris and lint generated in the working area of ​​the sewing machine; the inlet end of the drainage channel 2 is connected to the top opening of the suction hood 1 to facilitate the guidance of impurities adsorbed in the suction hood 1 into the drainage channel 2; two suction fans 3 are symmetrically installed on the bottom wall of the drainage channel 2 to facilitate the decompression of the suction hood 1 and the drainage channel 2, and to provide power for the adsorption work of the suction hood 1, which is beneficial to the subsequent cleaning work. Due to the suction of the suction fans 3, the debris generated during the operation of the sewing machine can be cleaned in conjunction with the suction hood 1 and the drainage channel 2, avoiding manual cleaning, and reducing the impact of debris on the needle during the operation of the sewing machine, so as to prevent the impact on the garment production progress.

[0021] Furthermore, the suction hood 1 is equipped with a rotatable blocking component 4, which includes a first filter screen 41. The first filter screen 41 is disposed inside the suction hood 1 to block debris and prevent it from directly entering the drainage channel 2, thus affecting the adsorption of debris. Two rotating shafts 42 are symmetrically welded to the side walls of the first filter screen 41, and another rotating shaft 42 is disposed in a rotating groove opened in the inner wall of the suction hood 1 to assist the rotation of the first filter screen 41. One rotating shaft 42 passes through a rotating hole opened in the side wall of the suction hood 1 and is fixedly connected to a rotating head 43 disposed on the outside of the suction hood 1, so that rotating the rotating head 43 can drive the first filter screen 41 to flip, facilitating the subsequent cleaning of debris adsorbed on the first filter screen 41. The other ends of the two springs 44 are fixedly connected to the side wall of the rotating head 43, and one end of the two springs 44 is connected to two T-shaped inserts 4. The pull end of 5 is connected, and the locking ends of the two T-shaped inserts 45 are respectively set in the sliding holes symmetrically opened on the rotating head 43, and are also located in the positioning holes symmetrically opened on the outer wall of the suction hood 1. This is used to restrict the position of the rotating head 43 and prevent the first filter screen 41 from rotating during the suction process. When it is necessary to flip the first filter screen 41 for cleaning, the locking ends of the T-shaped inserts 45 are pulled to disengage from the positioning holes, thereby releasing the restriction on the rotating head 43. Rotating the rotating head 43 can complete the swapping of the adsorption surface of the first filter screen 41, which is convenient for subsequent cleaning of debris on its adsorption surface to prevent blockage and affect subsequent suction. At the same time, after the first filter screen 41 is swapped, the locking ends of the two T-shaped inserts 45 are locked back in the positioning holes under the elastic action of the spring 44 to prevent the first filter screen 41 from moving during the cleaning process and affecting the cleaning work.

[0022] Furthermore, a cleaning component 5 is arranged on the suction hood 1 to facilitate cleaning of the blocking component 4. The cleaning component 5 includes a support base 51, which is fixedly installed on one side outer wall of the suction hood 1. A forward and reverse motor 52 is installed on the support base 51 and supported by the support base 51. A threaded rod 53 is located in the inner cavity of the suction hood 1, and a cleaning brush 54 is set in an internal groove opened on the side wall of the inner cavity of the suction hood 1. The opening of the internal groove allows the cleaning brush 54 to be hidden in the non-cleaning state, so as not to affect the rotation of the first filter screen 41. A guide groove is also opened on the top wall of the inner cavity of the suction hood 1, and the threaded rod 53 is set in the guide groove. The guide groove has the same function as the internal groove to avoid affecting the rotation of the first filter screen 41. A protrusion on the top of the cleaning brush 54 is provided with The cleaning brush 54 is fitted onto the threaded rod 53 through a threaded hole. The bottom cleaning surface of the cleaning brush 54 is in close contact with the top of the first filter screen 41, which facilitates the cleaning brush 54 to clean the adsorption surface of the first filter screen 41 during the rotation of the threaded rod 53. In conjunction with the suction fan 3, it helps to suck the cleaned debris and lint into the drainage channel 2, thereby achieving the purpose of cleaning the first filter screen 41 and preventing it from clogging and affecting the subsequent suction of the sewing machine working area. A bearing seat is installed in the guide groove. The rotating end of the bearing seat is connected to the end of the threaded rod 53 to assist the rotation of the threaded rod 53. A through hole is opened on one side wall of the guide groove. One end of the threaded rod 53 passes through the through hole and is connected to the output end of the forward and reverse motor 52, which facilitates the rotation of the threaded rod 53 by the forward and reverse motor 52.

[0023] Furthermore, a collection component 6 is provided inside the drainage channel 2 to facilitate the centralized collection of debris. The collection component 6 includes a storage box 61. An opening is provided on the back wall of the drainage channel 2. The storage area of ​​the storage box 61 extends through the opening and is located inside the drainage channel 2. A handle 62 is welded to the outer wall of the storage box 61, making it convenient for workers to pull the storage box 61 to move. A second filter 63 is installed in the bottom opening of the storage box 61 and is located above the suction end of the suction fan 3. This helps to guide the debris entering the drainage channel 2 into the storage box 61 for centralized collection and processing, while preventing debris from entering the suction fan 3 and damaging its internal structure.
