Description

Technical Field

[0001] The utility model belongs to the technical field of sewing machines, in particular to a workbench for sewing machines. Background Art

[0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on fabric, leather or other products, so as to interweave or sew one or more layers of sewing materials. It is widely used in sewing factories or other industrial sectors. The existing sewing machine workbench technology has the following problems: the existing sewing machine workbench has a certain limit on the area of the table, which makes it easy for the workpiece to fall off and come into contact with the ground, thereby contaminating the fabric and causing contamination of the fabric. At the same time, the small table area is not conducive to the development of work, making it uncomfortable for users to use and hindering the normal progress of work.

[0003] The Chinese utility model patent with publication number CN210394786U discloses a workbench of a sewing machine, which is provided with two table surfaces, a workbench and a sliding storage table. When the workbench needs to be used for work, the storage slide on the sliding storage table is pushed. Since the T-shaped slider at the bottom of the storage slide is arranged in the T-shaped slide groove on the workbench, the T-shaped slider can move on the workbench together with the sliding storage table, and the "T-shaped structure" of the T-shaped slider and the T-shaped slide groove can ensure that the T-shaped slider will not fall out of the slide groove, thereby ensuring that the sliding storage table will not be separated from the workbench. When the movement is completed, the locking hole on the sliding storage table is made to coincide with the locking hole on the workbench, and the fixing threaded rod on the fixing bolt is screwed into the locking hole on the workbench and the locking hole on the sliding storage table in sequence, so that the sliding storage table is securely fixed to the workbench, thereby expanding the area of the workbench. However, the device still has some other problems. For example, when the device is in use, it lacks a positioning guide component, which cannot prevent the fabric from being distorted and wrinkled during sewing, affecting the quality of the finished product.

[0048] Example 2:

[0049] This embodiment provides a workbench for a sewing machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0050] like Figure 1-Figure 3 As shown, in this embodiment, a groove 110 is provided on the lower surface of the workbench body 100, and a through groove 120 is also provided on the workbench body 100.

[0052] Example 3:

[0053] This embodiment provides a workbench for a sewing machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0054] like Figure 1-Figure 3 As shown, in this embodiment, the transmission mechanism 310 includes:

[0055] Two rotating shafts 311 are arranged transversely inside the groove 110;

[0056] Four rollers 312 are fixedly disposed at both ends of the rotating shaft 311;

[0057] The conveyor belt 313 is disposed between the two rotating shafts 311 . The conveyor belt 313 is fixedly mounted on the roller 312 and is driven by the feed port 330 .

[0058] The motor 314 is fixedly disposed on the side plate of the workbench body 100 , and the output shaft of the motor 314 passes through the side plate and is fixedly connected to one end of the rotating shaft 311 .

[0059] In the present technical solution, in order to enable the transmission mechanism 310 to transfer the fabric to the orienting mechanism 300 for limiting, two rotatable rotating shafts 311 are provided inside the groove 110 perpendicular to the direction of the through groove 120, and rollers 312 are fixedly provided on the rotating shafts 311 below both ends of the through groove 120. A conveyor belt 313 is set on the roller 312 under the same through groove 120, and a motor 314 is fixedly provided on the outside of the workbench body 100. The output shaft of the motor 314 passes through the side plate of the workbench and is fixedly connected to one end of one of the rotating shafts 311. Driven by the motor 314, the rotating shaft 311 can drive the roller 312 to rotate, thereby being able to bring The movable conveyor belt 313 rotates, and one end of the conveyor belt 313 is limited inside the inlet and outlet port 330. At the same time, the upper surface of the conveyor belt 313 limited inside the inlet and outlet port 330 is flush with the upper surface of the workbench body 100, so that the fabric is placed on the conveyor belt 313, and the transmission belt can move with the fabric. When passing through the orienting mechanism 300, it can be limited by the fixed rod 370. The symmetrical orienting mechanisms 300 on the left and right sides can synchronously limit the two sides of the fabric. In this way, when the sewing machine body 200 sews the fabric, the conveyor belt 313 can load the fabric, and the orienting mechanism 300 can limit the fabric on the conveyor belt 313, thereby facilitating the sewing of the fabric.

[0060] Example 4:

[0061] This embodiment provides a workbench for a sewing machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0062] like Figure 1-Figure 3 As shown, in this embodiment, an electromagnet 130 is fixedly installed on the inner wall of the groove 110 between the upper and lower layers of the conveyor belt 313, and the electromagnet 130 is arranged close to the upper layer of the conveyor belt 313, and the electromagnet 130 is arranged between the two rollers 312.

[0063] In the present technical solution, in order to enable the fixed rod 370 to contact the fabric on the upper surface of the transmission belt for positioning, an electromagnet 130 is arranged between the upper and lower layers of the conveyor belt 313. One end of the electromagnet 130 is fixed on the inner wall of the groove 110. The electromagnet 130 is arranged between the two rollers 312. In this way, the electromagnet 130 can generate a magnetic field when energized to generate a differential magnetic force on the fixed top rod, thereby driving the fixed rod 370 closer to the transmission belt, so that the fabric can be limited between the transmission belt and the fixed rod 370.

[0064] Example 5:

[0065] This embodiment provides a workbench for a sewing machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0066] like Figure 2 and Figure 3 As shown, in this embodiment, the fixing rod 370 is made of ferromagnetic material, a rotatable limiting ball 380 is provided below the fixing rod 370 , and the electromagnet 130 is electrically connected to the motor 314 .

[0067] In the present technical solution, in order to enable the fixing rod 370 to be attracted by the magnetic force generated when the electromagnet 130 is energized, the fixing rod 370 is made of ferromagnetic material, which can be iron or steel. A ball mounting hole is provided at the bottom end of the fixing rod 370, and a movable and rotatable limiting ball 380 is installed inside the mounting hole. In this way, when the electromagnet 130 generates attraction to the fixed top rod, the limiting ball 380 contacts the fabric on the conveyor belt 313. In this way, when the conveyor belt 313 drives the fabric to be loaded, the fabric will not be unable to be transported due to the squeezing of the fixed plate and the conveyor belt 313. When the conveyor belt is driven, the movable limiting ball 380 has a smaller contact area with the fabric and will not affect the rate at which the fabric is transported by the conveyor belt 313. In addition, the upper surface of the conveyor belt 313 can also be set to a rough surface to increase the grip between the fabric and the conveyor belt 313 to help transport the fabric.

[0068] Example 6:

[0069] This embodiment provides a workbench for a sewing machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0070] like Figure 2 and Figure 3 As shown, in this embodiment, the pulling force of the spring 350 on the sliding plate 360 is smaller than the suction force of the electromagnet 130 on the fixed rod 370 located directly above the electromagnet 130 .

[0071] In the present technical solution, in order to facilitate the placement of fabric into the orientation mechanism 300 before it is sewn, the pulling force of the spring 350 on the sliding plate 360 is made greater than the weight of the spring 350, the sliding plate 360 and the fixing rod 370 themselves. When the electromagnet 130 is not energized, the spring 350 drives the sliding plate 360 and the fixing rod 370 below the sliding plate 360 to retract inside the sliding groove 340. When the electromagnet 130 is energized, the pulling force of the spring 350 is slightly less than the suction force generated by the electromagnet 130. In this way, when the electromagnet 130 is energized to generate magnetic force, The fixing rod 370 and the limiting ball 380 exert a slight squeezing force on the fabric, thereby limiting the fabric position without affecting the fabric's transportation. In addition, the power supply to the electromagnet 130 is electrically connected to the motor 314. Before the motor 314 is energized, a gap is left between the fixing rod 370 and the conveyor belt 313 below, making it easier for people to place the fabric into the inlet and outlet 330. After the fabric is placed, the motor 314 starts to drive the conveyor belt 313 to load the fabric. The power supply to the electromagnet 130 also controls the fixing rod 370 to contact the fabric inside the inlet and outlet 330, thereby facilitating the installation of the fabric. A winding mechanism can also be provided behind the presser foot 220 to wind up the stitched fabric to prevent fabric accumulation from affecting the stitching (because this is a common structure, it will not be described in detail here).

[0072] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
