Description

Technical Field

[0001] The utility model relates to the technical field of roller car equipment, in particular to a roller car with a weft winding mechanism. Background Technique

[0002] A roller car, also known as an industrial sewing machine, is a sewing machine suitable for mass-producing sewn workpieces in sewing factories or other industrial departments. The roller car features high speed, high efficiency, and high precision. Through transmission methods such as electric motors and pedals, it is faster and more accurate than manual sewing. The pressure of the machine's sole and the coil can also be adjusted to adapt to different materials. A roller car with a weft winding mechanism can ensure that the fabric does not twist during operation, improving the sewing speed and efficiency.

[0003] As disclosed in the utility model with the authorization announcement number CN216998830U, a thread guiding device for a sewing machine drives a transmission gear to rotate by turning a handle. The transmission gear drives the upper rack and the lower rack to move towards each other, which can drive two sliders to slide towards each other in two chutes respectively, thereby adjusting the distance between the two traction wheels and facilitating the adjustment of the thread tension. By turning a turntable to drive a spur gear to rotate, the support plate can be driven to move on the straight rack, facilitating the removal or placement of the bobbin.

[0004] The following problems still exist when using this prior art:

[0005] The device has a poor limiting effect on the traction wheels. When the traction wheels pull the thread, if the thread is in close contact with the traction wheels and the pressure exerted on the traction wheels is large, it is easy to drive the traction wheels to move, thereby driving the two groups of traction wheels to move towards each other, changing the distance between the traction wheels, affecting the thread tensioning effect of the traction wheels, and reducing the sewing efficiency. The device has a poor limiting effect on the support plate. After the support plate completes the position adjustment, it is easy to move up and down under the influence of gravity or accidental contact from the external environment, further reducing the sewing efficiency.

Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0026] Embodiment

[0027] Please refer to Figures 1 - 3 As shown, the present utility model provides a roller car with a winding belt mechanism, including a base 1, a roller car body 2, a support plate 7 and a traction wheel 8. The top surface of the base 1 is fixedly installed with a roller car body 2 and a support column 6. There are two pairs of traction wheels 8 arranged above the roller car body 2. A rack 17 is fixedly arranged on the inner wall of the support column 6. A support plate 7 is arranged outside the support column 6. The support column 6 penetrates through the support plate 7 and is slidably connected with the support plate 7. A gear 18 is rotatably connected to the inner side of the support plate 7. The rack 17 is meshed with the gear 18. The rotation of the gear 18 can drive the gear 18 to move up and down along the rack 17, thereby driving the support plate 7 to move up and down along the support column 6. A winding drum 4 is fixedly installed on the top surface of the support plate 7, and a threading ring 5 is fixedly installed on the side surface of the support plate 7.

[0028] As Figures 1 - 4 shown, a first limiting component is arranged on the back of the traction wheel 8. The first limiting component is composed of a tensioner 3, a knob 10, a first threaded rod 11, a lifting sleeve 12, a connecting rod 13 and a sliding plate 14. The tensioner 3 is fixedly arranged on the top surface of the roller car body 2. The knob 10 is rotatably connected to the top surface of the tensioner 3. The first threaded rod 11 is fixedly arranged on the bottom surface of the knob 10. The first threaded rod 11 penetrates through the tensioner 3 to the inside of the tensioner 3. The bottom surface of the first threaded rod 11 is rotatably connected to the bottom surface inside the tensioner 3. The lifting sleeve 12 is threadedly connected to the outside of the first threaded rod 11. Symmetrical connecting rods 13 are hinged on the left and right sides of the lifting sleeve 12. The other side of the connecting rod 13 is hinged to the sliding plate 14. The traction wheel 8 is installed on the front surface of the sliding plate 14. The upper and lower sides and the front and rear sides of the sliding plate 14 are respectively slidably connected to the inner wall of the tensioner 3. Rotating the knob 10 drives the first threaded rod 11 to rotate. The rotation of the first threaded rod 11 drives the lifting sleeve 12 to move up or down along the first threaded rod 11. The movement of the lifting sleeve 12 drives the connecting rod 13 to rotate. The rotation of the connecting rod 13 drives the sliding plates 14 to approach or move away from each other, thereby changing the distance between the traction wheels 8. After the adjustment of the distance between the traction wheels 8 is completed, the line presses tightly on the traction wheels 8 and it is difficult to drive the traction wheels 8 to move, thereby avoiding affecting the tensioning effect of the traction wheels 8 on the line and improving the sewing efficiency.

[0029] As Figures 1 - 4As shown in the figure, a bolt 9 is threadedly connected to the inner side of the traction wheel 8. A first connecting block 15 is fixedly arranged on the back surface of the traction wheel 8. The bolt 9 passes through the traction wheel 8 and the first connecting block 15 respectively. A plurality of threaded grooves 16 are arranged on the front surface of the sliding plate 14. The bolt 9 is threadedly connected to the sliding plate 14 through the threaded groove 16. Rotating the bolt 9 drives the bolt 9 to disengage from the threaded groove 16, and the height of the traction wheel 8 can be adjusted. After the height adjustment of the traction wheel 8 is completed, align the first connecting block 15 with the nearest threaded groove 16, and rotate the bolt 9 in the reverse direction so that the bolt 9 is threadedly connected to the sliding plate 14 through the threaded groove 16 until the bolt 9 presses the traction wheel 8, thereby limiting the position of the traction wheel 8.

[0030] As Figures 1 - 6 shown in the figure, a second limiting component is arranged above the base 1. The second limiting component is composed of a second connecting block 19, a turntable 20, a stop block 21, a second threaded rod 22, a pull rod 23, a serrated block 24 and a serrated groove 25. A chute is arranged inside the support plate 7. The gear 18 is slidably connected to the support plate 7 through the chute. The thickness of the gear 18 is less than that of the rack 17. A second connecting block 19 is fixedly arranged on the side surface of the gear 18. The second connecting block 19 passes through the support plate 7 and is rotatably connected to the support plate 7. On the other side of the second connecting block 19, a turntable 20 is fixedly arranged. A plurality of serrated blocks 24 are arranged in a circumferential array on the outer side of the turntable 20. A pull rod 23 is fixedly arranged on the side of the turntable 20 away from the second connecting block 19. A serrated groove 25 is arranged on the side surface of the support plate 7. The serrated block 24 is adapted to the serrated groove 25. The turntable 20 is snap-connected to the serrated groove 25 of the support plate 7 through the serrated block 24. A second threaded rod 22 is threadedly connected to the side surface of the support plate 7. A stop block 21 is fixedly arranged on the side of the second threaded rod 22 away from the support plate 7. Rotating the stop block 21 drives the second threaded rod 22 to rotate by 90 degrees, so that the stop block 21 disengages from the turntable 20, and then pulling the pull rod 23 outwards drives the turntable 20 to move outwards. The movement of the turntable 20 drives the second connecting block 19 and the gear 18 to move outwards. During the movement of the gear 18, it is always meshed with the rack 17. When the serrated block 24 disengages from the serrated groove 25, rotating the turntable 20 drives the second connecting block 19 to rotate. The rotation of the second connecting block 19 drives the gear 18 to rotate, thereby driving the support plate 7 to move up and down along the support column 6. After the position adjustment of the support plate 7 is completed, pressing the turntable 20 to engage the serrated block 24 in the serrated groove 25 can prevent the turntable 20 from rotating relative to the support plate 7. Rotating the stop block 21 in the reverse direction drives the stop block 21 to move back to its original position and closely adhere to the turntable 20, thereby limiting and fixing the position of the support plate 7 and further improving the sewing efficiency.

[0031] Specific working principle:

[0032] When the device is in use, rotate the stopper 21 to drive the second threaded rod 22 to rotate by 90 degrees, so that the stopper 21 disengages from the turntable 20. Then, pull the pull rod 23 outwards to drive the turntable 20 to move outwards. The movement of the turntable 20 drives the second connecting block 19 and the gear 18 to move outwards. During the movement of the gear 18, it is always meshed with the rack 17. When the serrated block 24 disengages from the serrated groove 25, rotate the turntable 20 to drive the second connecting block 19 to rotate. The rotation of the second connecting block 19 drives the gear 18 to rotate, thereby driving the support plate 7 to move downwards along the support column 6, facilitating the taking and placing of the bobbin 4. After the position adjustment of the support plate 7 is completed, press the turntable 20 to engage the serrated block 24 in the serrated groove 25, which can prevent the turntable 20 from rotating relative to the support plate 7. Rotate the stopper 21 in the reverse direction to drive the stopper 21 to move back to its original position and closely adhere to the turntable 20, thereby limiting and fixing the position of the support plate 7. Thread the thread on the bobbin 4 through the threading ring 5, and then successively bypass the traction wheels 8 on the side of the tensioner 3 at one end. Subsequently, thread the end of the thread on the needle to achieve the threading operation of the sewing machine.

[0033] When it is necessary to adjust the spacing of the traction wheels 8, rotate the knob 10 to drive the first threaded rod 11 to rotate. The rotation of the first threaded rod 11 drives the lifting sleeve 12 to move up or down along the first threaded rod 11. The movement of the lifting sleeve 12 drives the connecting rod 13 to rotate. The rotation of the connecting rod 13 drives the sliding plates 14 to approach or move away from each other, thereby changing the spacing of the traction wheels 8. After the adjustment of the spacing of the traction wheels 8 is completed, the line presses the traction wheels 8, making it difficult to drive the traction wheels 8 to move, thereby avoiding affecting the tensioning effect of the line on the traction wheels 8 and improving the sewing efficiency.

[0034] When it is necessary to adjust the height of the traction wheels 8, rotate the bolt 9 to drive the bolt 9 out of the threaded groove 16 to adjust the height of the traction wheels 8. After the height adjustment of the traction wheels 8 is completed, align the first connecting block 15 with the nearest threaded groove 16, and rotate the bolt 9 in the reverse direction so that the bolt 9 is threadedly connected to the sliding plate 14 through the threaded groove 16 until the bolt 9 presses the traction wheels 8, thereby limiting the position of the traction wheels 8.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
