Description

Technical Field

[0001] The utility model relates to the technical field of sock production equipment, in particular to a knitting density adjusting device for sock production. Background Technique

[0002] Socks are a kind of clothing item worn on the feet, generally made of knitting threads. Specifically, during the sock knitting process, in order to improve the knitting efficiency, a loom is usually used to knit socks. Among them, a circular weft knitting machine can knit the knitting threads into a cylindrical shape to facilitate subsequent sock processing. However, during the sock production process, according to the different sizes of socks, it is necessary to adjust the knitting density to control the knitting density of the socks.

[0003] Usually, during the use of a circular weft knitting machine, in order to prepare fabrics with different densities, workers need to manually adjust the number of stitches and the distance between two adjacent knitting needles in sequence to control the knitting density and adjust the fabric density. However, since the number of knitting needles includes hundreds, when workers adjust the position of each group of knitting needles in sequence, it will increase the working hours of the workers, not only wasting the adjustment time, but also prone to errors during the adjustment process. For this reason, we have proposed a knitting density adjusting device for sock production. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing knitting density adjusting device for sock production, the utility model provides a knitting density adjusting device for sock production, which has the advantages of rotating the second gear, that is, the second gear drives each group of screws to rotate synchronously, that is, when the screw can push the fixed seat to move inward, it improves the convenience. At the same time, by flipping the positioning pin, when changing the number of stitches, it avoids unused knitting needles being arranged inside the main body of the knitting equipment, resulting in an impact on subsequent knitting. The problems raised in the above background technique are solved.

[0005] The utility model provides the following technical solutions: A knitting density adjusting device for sock production includes a main body of knitting equipment. A placement groove is opened inside the main body of the knitting equipment. A screw is installed inside the lower end of the placement groove. A first bevel gear is fixedly connected to the side of the screw. A gear set is meshed and connected to the side of the first bevel gear. The lower part of the main body of the knitting equipment is fixedly connected with a first positioning sleeve. At the same time, a first gear is movably sleeved inside the first positioning sleeve. A fixed seat is threadedly sleeved outside the screw. A vertical rod is sleeved inside the fixed seat. A positioning pin is installed at the front end of the fixed seat. A second positioning sleeve is fixedly connected to the upper end inside the placement groove. A movable rod is fixedly connected inside the second positioning sleeve. A sliding block is sleeved outside the movable rod. A positioning pad is fixedly connected to the inner side of the sliding block.

[0006] Preferably, the gear set includes a set of gears and another set of helical gears, and the gears inside the gear set are meshed and connected to the first gear with each other.

[0007] Preferably, a second gear is meshed and connected to the inner side of the first gear. The second gear is installed inside the first positioning sleeve, and the middle part of the second gear is connected to the output shaft of the motor.

[0008] Preferably, the fixing seat is arranged inside the placing groove. A limiting plate is installed at the front end inside the fixing seat, and the positioning pin is arranged at the rear end of the vertical rod.

[0009] Preferably, a movable rod is movably sleeved inside the vertical rod, and a knitting needle is installed inside the movable rod.

[0010] Preferably, the positioning pad is filled with nitrogen, and the positioning pads are installed on both sides of the knitting needle.

[0011] Preferably, a track is fixedly connected to the outside of the knitting equipment main body, and the track is provided with an opening on the side located at the placing groove.

[0012] Compared with the existing knitting density adjusting device for sock production, the present utility model has the following beneficial effects:

[0013] 1. For the knitting density adjusting device for sock production, by starting the motor installed outside the second gear, the motor drives the second gear to rotate. Meanwhile, under the auxiliary transmission of the first gear and the gear set, the screw rod can be driven to rotate. The screw rod and the fixing seat perform a meshing movement. By adjusting the inward movement distance of the fixing seat, the knitting density can be adjusted. Moreover, by starting the second gear, multiple groups of fixing seats can be driven to be adjusted synchronously, avoiding the problem of wasting time caused by adjusting the positions of the fixing seats separately.

[0014] 2. For the knitting density adjusting device for sock production, the vertical rod is installed inside the fixing seat. By removing the positioning pin, the positioning pin can be driven to flip, that is, according to different knitting processes, the number of stitches can be adjusted. Meanwhile, when the knitting machine head moves, the knitting needle is prevented from affecting the movement of the knitting machine head. At the same time, a positioning pad is arranged on the inner side of the placing groove, and the positioning pad is clamped on the side of the knitting needle. That is, when the knitting needle moves, the positioning pad limits the position of the knitting needle, preventing the knitting needle from being damaged due to pressure.

[0024] Reference Figure 5 , The gear set 5 includes a set of gears and another set of bevel gears. At the same time, the gears inside the gear set 5 are meshed and connected with the first gear 6. Through the two ends of the gear set 5 being respectively meshed and connected with the first bevel gear 4 and the first gear 6, that is, when the first gear 6 rotates, the first gear 6 drives the gear set 5 to rotate. Through the gear set 5 driving multiple sets of first bevel gears 4 to rotate synchronously, that is, when the first bevel gear 4 drives the screw rod 3 to rotate, the screw rod 3 can synchronously drive the position of the fixed seat 9 inside the placement groove 2 to be adjusted, improving the convenience when adjusting the position of the fixed seat 9 inside the placement groove 2.

[0025] Reference Figure 4 and Figure 5 , The inner side of the first gear 6 is meshed and connected with a second gear 8. The second gear 8 is installed inside the first positioning sleeve 7. At the same time, the middle part of the second gear 8 is connected to the output shaft of the motor. By starting the motor installed outside the second gear 8, the motor drives the second gear 8 to rotate through the output shaft. At the same time, a meshing movement occurs between the second gear 8 and the first gear 6. Thus, the first gear 6 can drive the gear set 5 to rotate synchronously.

[0026] Among them, the fixed seat 9 is arranged inside the placement groove 2. A limit plate is installed at the front end inside the fixed seat 9. At the same time, the positioning pin 11 is arranged at the rear end of the vertical rod 10. By arranging the fixed seat 9 inside the placement groove 2, the movement track of the fixed seat 9 is limited by the placement groove 2. And the vertical rod 10 is arranged inside the fixed seat 9. By adjusting the position of the positioning pin 11, the positioning pin 11 can drive the vertical rod 10 to be limited in position inside the fixed seat 9. And by loosening the positioning pin 11, after the positioning pin 11 reduces the position limitation on the vertical rod 10, the vertical rod 10 is flipped, and the vertical rod 10 moves to the side, that is, it avoids the knitting needle 13 from moving upwards.

At the same time, according to the different moving distances of the knitting needle 13 towards the inner side, the positioning pads 17 can be sleeved on the positioning pads 17 to ensure the stability of the knitting needle 13 when it moves.

[0029] Reference Figure 1 , an orbit 18 is fixedly connected to the outside of the knitting equipment main body 1. The orbit 18 is provided with an opening on the side located at the placement groove 2. By fixedly connecting the orbit 18 to the outside of the knitting equipment main body 1, the orbit 18 can drive the knitting machine head to provide a movement track. At the same time, an opening is provided on the side of the orbit 18 located at the placement groove 2. When the knitting needle 13 is flipped, the opening provides a movement space for the knitting needle 13.

[0030] Working principle: When in use, the knitting needles 13 are installed inside the movable rod 12, and a circle is formed by the knitting needles 13. That is, when the knitting needles 13 are knitting socks, the socks can be prepared into a circular shape. At the same time, when it is necessary to adjust the knitting density, the motor installed outside the second gear 8 is started. The motor drives the gear set 5 to rotate through the first gear 6. Through the linkage relationship, a threaded movement is carried out between the screw 3 and the fixed seat 9, and the fixed seat 9 is pushed to move inward, that is, the distance between the two sets of knitting needles 13 is adjusted, and then the knitting density can be controlled. And when it is necessary to adjust the number of stitches, the positioning pin 11 can be removed, and at the same time, the knitting needle 13 is flipped, that is, the knitting needle 13 is flipped to the side, and then the number of stitches can be adjusted. And the positioning pad 17 is arranged on the side of the knitting needle 13, that is, the positioning pad 17 limits the position of the knitting needle 13, improves the stability of the knitting needle 13 when moving, and avoids the problem of breakage caused by pressure when the knitting needle 13 moves.
