DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0021] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and material examples provided by the present application, but those of ordinary skill in the art can appreciate the application of other processes and / or the use of other materials.

[0022] The embodiment of the present application provides a fabric pressing mechanism of a sewing machine, which can be installed on a variety of different sewing machine tables using an installation component, so that the device can be installed on different sewing machines, improving the applicability of the device. At the same time, the workpiece can be flattened in two rounds using a flattening component, which can provide a stable and flat fixing effect. The fabric pressing mechanism of the sewing machine is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0023] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0024] See also Figure 1-5 In Example 1

[0025] The present embodiment provides a fabric pressing mechanism for a sewing machine, comprising: two pressure strips 1, which are arranged opposite to each other, and a connecting rod 101 is provided between the two pressure strips 1, and a press switch 4 is provided on one side of the pressure strip 1; a flattening component, which is arranged inside the pressure strip 1 and is used to blow and flatten the fabric on one side of the pressure strip 1; and an installation component, which is arranged at the bottom of the pressure strip 1 and is used to adsorb and fix the surface of the sewing machine, so as to install the device on the sewing machine.

[0026] Furthermore, the flattening component includes: a plurality of air inlets 2 opened inside the pressure strip 1, a filter 201 is provided on the top of the air inlet 2; an air blow pipe 203 is provided at the bottom of the air inlet 2, and the air blow pipe 203 is arranged toward the side away from the pressure strip 1; a blower 202 is provided inside the air inlet 2. During use, the user can start the blower 202 by pressing the switch 4. At this time, the blower 202 will create airflow inside the air inlet 2. After passing through the air inlet 2, the airflow reaches the air blow pipe 203, and blows the air onto the surface of the workpiece along the inclined air blow pipe 203. In this way, the part of the fabric to be sewn can be blown, so that the subsequent feeding of the fabric can be straighter. The filtering of the passing airflow by the filter 201 can prevent dust in the air from being blown onto the workpiece, thereby improving the practicality of the device.

[0027] Furthermore, a storage chamber 3 is provided at the bottom of the pressure strip 1, and a central axis 301 is rotatably connected inside the storage chamber 3. A compacting roller 302 is provided on the surface of the central axis 301, and the compacting roller 302 is located on one side of the plurality of air blowing pipes 203. After the first step of flattening, the compacting roller 302 can flatten the workpiece passing under the pressure strip 1 for the second time, thereby preventing the workpiece from being in a wrinkled or bent state after passing through the pressure strip 1. At the same time, when the compacting roller 302 rotates under the traction of the workpiece, it will rub other parts of the workpiece that are not tractioned. For example, when the middle part of the cloth moves toward the user due to the pulling force of the user, the compacting roller 302 will rotate and flatten the cloth. While flattening it, the rotation of the compacting roller 302 will also drive the left and right parts of the cloth located below the compacting roller 302 to frictionally push, so that the left and right sides of the cloth can also move toward the user synchronously with the cloth. In this way, when the user pulls the cloth, the feeding of the cloth will be more uniform and stable, preventing the uneven feeding of the cloth from causing the tailoring process to become skewed.

[0028] Furthermore, a flexible cushion layer 303 is provided on the surface of the compacting roller 302, and the flexible cushion layer 303 is made of sponge material. During use, the flexible cushion layer 303 can be used to pressurize the contact surface between the compacting roller 302 and the workpiece, so that the friction between the workpiece and the compacting roller 302 is greater, thereby allowing the workpiece to be better loaded and improving the practicality of the device.

[0029] Example 2

[0030] On the basis of Example 1, the installation component includes: an adsorption chamber 102 opened at the bottom of the pressure strip 1, and an adsorption plate 104 is slidably connected to the inside of the adsorption chamber 102; a threaded rod 105 rotatably connected to the inside of the adsorption chamber 102 through a ball bearing, and the threaded rod 105 is threadedly engaged with the adsorption plate 104; a rotating plate 106 is arranged on the top of the threaded rod 105. During use, the user can place the pressure strip 1 on the table of the sewing machine, at which time the adsorption chamber 102 will fit with the top surface of the sewing machine, and the user can rotate the rotating plate 106 to drive the threaded rod 105 to rotate, and the threaded rod 105 will fit with the The upper adsorption plate 104 is threadedly engaged. Under the action of the threaded engagement, the adsorption plate 104 will move upward. At this time, the cavity inside the adsorption chamber 102 becomes larger while the amount of air at the bottom of the adsorption chamber 102 remains unchanged, resulting in the bottom of the adsorption chamber 102 being in a negative pressure state. Under the negative pressure state, the adsorption chamber 102 will adhere to the surface of the sewing machine, and the pressure strip 1 can be firmly adsorbed on the table of the sewing machine. In this way, the pressure strip 1 can be fixed to the table of various sewing machines without reserving a special installation position or using structures such as threads for installation, thereby improving the applicability of the device.

[0031] Furthermore, two sealing strips 103 are provided at the edge of the adsorption chamber 102. Both of the two sealing strips 103 are rectangular rings, and a gap is provided between the two sealing strips 103. During use, the user can fix the pressure strip 1 on the table top of the sewing machine through the adsorption chamber 102. At this time, the two sealing strips 103 are used to seal the gap between the edge of the adsorption chamber 102 and the table top to prevent external air from entering the adsorption chamber 102. The two sealing strips 103 are used to be nested with each other, which can prevent, for example, the outer single sealing strip 103 from leaking or the inner single sealing strip 103 from leaking, resulting in unstable adsorption of the device, thereby improving the installation stability of the device.

[0032] Furthermore, a plurality of anti-skid grooves 107 are provided on the surface of the rotating plate 106, and the plurality of anti-skid grooves 107 are equidistantly distributed around the circumference of the rotating plate 106. The anti-skid grooves 107 can increase the friction between the rotating plate 106 and the user's hand, allowing the user to more conveniently rotate the rotating plate 106 to drive the threaded rod 105 to rotate, thereby improving the ease of use of the device.
