It is obvious that the drawings in the following description are only examples of the invention, from which other drawings can be obtained and from which other embodiments can be obtained without inventive effort for a person skilled in the art, and that the invention is not limited to these examples.
Please refer to fig. 1 to 5. The invention provides a mop wheel device of a sewing machine, which comprises a mop wheel assembly arranged on a machine head 1 of a lockstitch sewing machine, wherein the mop wheel assembly comprises an eccentric wheel 3 connected with a transmission shaft 2 on the machine head 1, an eccentric wheel connecting rod 4 arranged on the eccentric wheel 3, a mop wheel fixing frame 8 arranged on the machine head 1, a mop wheel rotating shaft 81 arranged on the mop wheel fixing frame 8, a mop wheel 82 fixed on a mop wheel rotating shaft 81, and a connecting rod 7 with one end rotationally connected with the eccentric wheel connecting rod 4 and the other end rotationally connected with a first rotating shaft 6 through a one-way bearing 5, and the machine head 1 is also provided with a mounting hole 9 for the first rotating shaft 6 to pass through; a conveyor belt 10 is connected between the mop wheel rotating shaft 81 and the first rotating shaft 6, and unidirectional rotation of the mop wheel 82 on the mop wheel fixing frame 8 is completed through the unidirectional bearing 5 and the conveyor belt 10.
It is added that the one-way bearing 5 is a bearing which can rotate freely in one direction and is locked in the other direction, and the purpose of this is that the eccentric wheel 3 is driven to rotate by the transmission shaft 2, so that the eccentric wheel connecting rod 4 pushes the connecting rod 7 to reciprocate and further drive the first rotating shaft 6 to rotate, and when the connecting rod 7 rotates, the first rotating shaft 6 is in a short stopping state until the next rotating process is entered due to the effect of the one-way bearing 5, and the rotation cannot occur, namely the one-way rotation of the first rotating shaft 6 is ensured.
Please refer to fig. 1, 3 and 5 again. In this example, the fabric clamping device may further include a driven mop wheel assembly and a groove 12 disposed on the frame 11 of the lockstitch sewing machine, the driven mop wheel assembly includes a mounting seat 13 disposed on the groove 12, a base 15 connected to the mounting seat 13 through two guide posts 14, a driven mop wheel support 16 having cylindrical holes 161 at two ends for the guide posts 14 to pass through, a driven shaft 162 disposed on the driven mop wheel support 16, and a driven mop wheel 17 disposed on the driven shaft 162, where the two guide posts 14 are further sleeved with a telescopic spring 18 for abutting against the bottom of the driven mop wheel support 16, and in this way, the driven mop wheel 17 is disposed to rotate in cooperation with the mop wheel 82 to clamp the fabric for transportation, and for thicker fabric, the driven mop wheel 17 can be pressed down, and is kept in good contact with the fabric through the telescopic spring 18, so as to cooperate with the mop wheel 82 to clamp the fabric for discharging.
Please refer to fig. 5 again. In this example, the lifting assembly is further configured to lift the driven mop wheel support 16 and includes a driven mop wheel lifting lever 19, a push rod 20 with one end connected to the driven mop wheel lifting lever 19, and a driving rod 21 with one end connected to the driven mop wheel lifting lever 19 and the other end passing through the through hole 151 on the base 15, where the driven mop wheel lifting lever 19 is deflected by stretching the push rod 20, so as to drive the driving rod 21 to move to complete lifting of the driven mop wheel support 16, so that the lifting assembly is used to raise the height of the driven mop wheel support 16 for thinner fabric, so that the driven mop wheel 17 can be abutted to the fabric, and the driven mop wheel 82 is matched to perform better clamping on the fabric to achieve the purpose of discharging.
To supplement, the driven mop wheel lifting lever 19 and the driving rod 21 and the ejector rod 20 form a lever structure, that is, the driven mop wheel lifting lever 19 swings around one fixed end thereof by stretching the ejector rod 20, so as to drive the driving rod 21 to move, and it should be understood that when the driven mop wheel lifting lever 19 swings, the driving rod 21 can be laterally displaced and vertically displaced, that is, the height changes, so that the driven mop wheel support 16 is driven to rise or fall by the base 15; the base 15 is provided with the guide posts 14, the guide posts 14 are driven to ascend when the base 15 ascends, the two guide posts 14 respectively penetrate through the two cylindrical holes 161 on the driven mop wheel support 16, the telescopic springs 18 are abutted between the base 15 and the driven mop wheel support 16, the telescopic springs 18 are compressed by the driven mop wheel support 16 when the guide posts 14 ascend to generate elastic force, and the driven mop wheel support 16 is further pushed to ascend, so that the driven mop wheel 17 ascends to abut against fabrics, and the aim of discharging thinner fabrics is achieved by matching with the mop wheel 82.
In this example, the lifting assembly further includes a second rotating shaft 22 fixed on the base 15, and a pulley 23 disposed on the second rotating shaft 22, where the driving rod 21 passes through the through hole 151 on the base 15 and then abuts against an inner wall of a groove (not shown in the figure) on the pulley 23, so that when the driven mop wheel lifting lever 19 swings, the driving rod 21 can generate a lateral displacement and a displacement in a vertical direction, and the displacement in the vertical direction can make the driven mop wheel 17 rise or fall, as described above. Then the transverse displacement can be solved by passing the transmission rod 21 through the through hole 151 on the base 15, so that when the transmission rod 21 is displaced in the transverse displacement and the vertical direction to drive the driven mop wheel support 16 to ascend or descend, the transmission rod 21 needs to be ensured to be displaced in the transverse direction effectively on the base 15, therefore, the transmission rod 21 passes through the through hole 151 on the base 15 and then is abutted against the inner wall of the groove (not shown in the figure) on the pulley 23 by arranging the second rotating shaft 22 and the pulley 23 on the base 15, thereby ensuring that the transmission rod 21 is effectively abutted against the transmission rod 21 through the two through holes 151 on the base 15 and the pulley 23, ensuring that the transmission rod 21 is effectively displaced in the transverse direction to drive the base to ascend, and simultaneously realizing the reduction of friction force with the transmission rod 21 to a certain extent by the rotation of the pulley 23, and prolonging the service life of the machine.
In this example, one embodiment of the transmission rod 21 may be an L-shaped transmission rod, and may be a steel wire with a suitable thickness to implement the function thereof.
Please refer to fig. 1 and fig. 4 again. In this example, the device may further include an adjusting member disposed on the machine head 1 for adjusting tightness of the conveyor belt 10, where the adjusting member includes an adjusting seat 24 having a bar-shaped hole 241, a column 242 disposed on the adjusting seat 24 for abutting against the conveyor belt 10, and a screw 25 for fixing the adjusting seat 24 through the bar-shaped hole 241; the belt pulley 26 for connecting the conveyor belt 10 can be arranged on the first rotating shaft 6 and the cloth dragging wheel rotating shaft 81, the position of the adjusting seat 24 on the machine head 1 can be adjusted through the strip-shaped hole 241 and the screw 25, and the extrusion force of the conveyor belt 10 can be further adjusted by the adjusting column 242, so that the tightness of the conveyor belt 10 in conveying or on the belt pulley 26 can be adjusted, and the better transmission is facilitated.
Please refer again to fig. 1 and 4. In this example, one embodiment of the mop wheel 82 may be provided with tooth grooves 821, including but not limited to tooth grooves 821, and may also be provided with protrusions, bar grooves, etc., which can increase certain friction to facilitate the fabric discharging.
In this case, a rubber film (not shown in the figure) may be sleeved on the driven cloth dragging wheel 17, so that the driven cloth dragging wheel 17 should have a certain friction force, so that the driven cloth dragging wheel does not slip when contacting with the fabric, and the driven cloth dragging wheel 82 is convenient to clamp the fabric and discharge the fabric.
