DETAILED DESCRIPTION

[0027] like Figures 1 to 3 As shown, it is the first embodiment of the cylindrical machine yarn guide disc transmission mechanism of the present invention, which is used to drive the cylindrical machine yarn guide disc device 60, and includes a driving wheel group 10, an upper connecting rod 20, an upper eccentric seat adjustment group 30, a lower connecting rod 40, a lower eccentric seat adjustment group 50, and a power source (not shown in the figure).

[0028] The driving wheel assembly 10 comprises a pivot 11, an upper driving wheel 12, a lower driving wheel 13, and a lower coupling seat 14. The upper driving wheel 12 is pivoted on the pivot 11, and the lower driving wheel 13 is fixed to the pivot 11 and located below the upper driving wheel 12. The end of the pivot 11 opposite to the upper driving wheel 12 is fixed to the lower coupling seat 14.

[0029] One end of the upper connecting rod 20 is connected to the top periphery of the upper driving wheel 12 of the driving wheel assembly 10 .

[0030] The upper eccentric seat adjustment group 30 is pivotally arranged at the end of the upper connecting rod 20 that is different from the upper driving wheel 12, and is used for adjusting the swing angle of the upper connecting rod 20 to drive the upper driving wheel 12 to reciprocate. The upper eccentric seat adjustment group 30 has an upper eccentric block 31, and the upper eccentric block 31 has an upper groove 310 arranged along the longitudinal direction. An upper sliding block 32 is arranged in the upper groove 310, and the upper sliding block 32 is detachably fixed in the upper groove 310, and the upper sliding block 32 is pivotally arranged at the end of the upper connecting rod 20 away from the upper driving wheel 12. The upper eccentric block 31 is axially provided with an upper transmission shaft 33, and the upper transmission shaft 33 is fixed with an upper transmission wheel 34 at a position different from the upper eccentric block 31. As shown in the figure, the upper transmission wheel 34 is arranged at an end of the upper transmission shaft 33 that is different from the upper eccentric block 31.

[0031] One end of the lower connecting rod 40 is pivotally mounted on the lower coupling seat 14 of the driving wheel assembly 10 and is away from one end of the pivot shaft 11 .

[0032] The lower eccentric seat adjustment group 50 is pivotally mounted on the end of the lower connecting rod 40 that is different from the lower coupling seat 14 of the driving wheel group 10, and is used to adjust the swing angle of the lower connecting rod 40 to drive the lower driving wheel 13 to reciprocate. The lower eccentric seat adjustment group 50 has a lower eccentric block 51, and the lower eccentric block 51 has a lower groove 510 arranged along the longitudinal direction. A lower sliding block 52 is provided in the lower groove 510, and the lower sliding block 52 is detachably fixed in the lower groove 510, and the lower sliding block 52 is pivotally mounted on the end of the lower connecting rod 40 away from the lower coupling seat 14. The lower eccentric block 51 is axially provided with a lower transmission shaft 53, and the lower transmission shaft 53 is fixed with a lower transmission wheel 54 at a position different from the lower eccentric block 51, and the lower transmission wheel 54 is horizontally arranged with the upper transmission wheel 34 of the upper eccentric seat adjustment group 30.

[0033] The power source (not shown) includes a belt that is sleeved between the upper transmission wheel 34 of the upper eccentric seat adjustment group 30 and the lower transmission wheel 54 of the lower eccentric seat adjustment group 50, and is driven by a motor to simultaneously drive the upper transmission wheel 34 of the upper eccentric seat adjustment group 30 and the lower transmission wheel 54 of the lower eccentric seat adjustment group 50 to rotate.

[0034] See also Figure 2 and Figure 4 When the upper eccentric seat adjustment group 30 drives the upper connecting rod 20 to link the upper driving wheel 12, the upper transmission shaft 33 of the upper eccentric seat adjustment group 30 will be driven by the power source (not shown) to rotate, so as to drive one end of the upper connecting rod 20 to move back and forth through the rotation of the upper sliding block 32, thereby linking the other end of the upper connecting rod 20 to drive the upper driving wheel 12 to reciprocate around the pivot 11 at an appropriate angle; similarly, please refer to Figure 2 and Figure 5 When the lower eccentric seat adjustment group 50 drives the lower connecting rod to link the lower driving wheel 13, the upper transmission shaft 33 of the lower eccentric seat adjustment group 50 will be driven by the power source (not shown) to rotate, so as to drive one end of the lower connecting rod 40 to move back and forth through the rotation of the lower sliding block 52, and then link the other end of the lower connecting rod 40 to sequentially drive the lower coupling seat 14, the pivot 11 and the lower driving wheel 13, so that the lower driving wheel 13 is centered on the pivot 11 and reciprocates at an appropriate angle. Through the above action, the upper driving wheel 12 and the lower driving wheel 13 of the driving wheel group 10 can be reciprocated at an angle to drive the lower driving wheel 13 to rotate back and forth. Figure 1 The yarn guide disc device of the cylindrical machine is used to crochet fabrics.

[0035] See also Figure 3 and Figure 6As shown, when the reciprocating rotation angle of the upper driving wheel 12 of the driving wheel assembly 10 needs to be adjusted, it is only necessary to adjust the position between the upper sliding block 32 and the upper groove 310, that is, the closer the upper sliding block 32 is set to the center position of the upper transmission shaft 33, the smaller the swing amplitude of the upper connecting rod 20 is, and the smaller the relative impact on the reciprocating rotation angle of the upper driving wheel 12 is; conversely, the farther the upper sliding block 32 is set from the center position of the upper transmission shaft 33, the greater the swing amplitude of the upper connecting rod 20 is, and the greater the relative impact on the reciprocating rotation angle of the upper driving wheel 12 is.

[0036] Similarly, see Figure 3 and Figure 7 As shown, when the reciprocating rotation angle of the lower driving wheel 13 of the driving wheel group 10 needs to be adjusted, it is only necessary to adjust the position between the lower sliding block 52 and the lower groove 510, that is, the closer the lower sliding block 52 is set to the center position of the lower transmission shaft 53, the smaller the swing amplitude of the lower connecting rod 40 is, and the smaller the relative impact on the reciprocating rotation angle of the lower driving wheel group 10 is; conversely, the farther the lower sliding block 52 is set from the center position of the lower transmission shaft 53, the larger the swing amplitude of the lower connecting rod 40 is, and the relative impact on the reciprocating rotation angle of the lower driving wheel 13 is. In this way, the yarn guide disc device 60 of the cylindrical machine can be increased to have better variability when crocheting fabrics. At the same time, through the structural design of this embodiment, the space of the overall transmission mechanism can be reduced, and only one set of power source is used to achieve the transmission effect, which further has the effect of reducing costs.

[0039] One end of the lower connecting rod 40 ′ is pivotally mounted on the lower coupling seat 14 ′ of the driving wheel assembly 10 ′ and is away from one end of the pivot shaft 11 ′.

The lower eccentric seat adjustment group 50' has a lower eccentric block 51', and the lower eccentric block 51 is fixed to the upper transmission shaft 33' of the upper eccentric seat adjustment group 30' and is different from one end of the upper eccentric block 31'. The lower eccentric block 51' has a lower groove 510' arranged in the longitudinal direction, and a lower sliding block 52' is provided in the lower groove 510'. The lower sliding block 52' is detachably fixed in the lower groove 510', and the lower sliding block 52' is pivotally mounted on the end of the lower connecting rod 40' away from the lower coupling seat 14'.
