As shown in fig. 4, the feeding device 10 includes a housing 100, a first driving wheel 200, a second driving wheel 300 and a driving mechanism 400, wherein the first driving wheel 200 is rotatably disposed on the housing 100, and the second driving wheel 300 and the first driving wheel 200 are disposed at an interval to form a feeding channel 201 for the thread 20 to pass through. The driving mechanism 400 drives the first driving wheel 200 and the second driving wheel 300 to rotate so as to convey the thread 20 in the feeding channel 201.
It can be understood that, since the wire 20 is clamped between the first driving wheel 200 and the second driving wheel 300, when the wire 20 needs to be replaced, if the size of the feeding path 201 between the first driving wheel 200 and the second driving wheel 300 cannot be adjusted, the wire 20 between the first driving wheel 200 and the second driving wheel 300 can only be pulled out and replaced, and the wire 20 is easily damaged, so the size of the feeding path 201 needs to be adjusted.
In an embodiment, referring to fig. 3, the feeding device 10 further includes an adjusting mechanism 600 and an elastic element 700, wherein the elastic element 700 is abutted between the housing 100 and the support 610 to provide an elastic restoring force to the support 610. The adjusting mechanism 600 is movably disposed in the housing 100, and the adjusting mechanism 600 is operated to adjust the size of the feeding passage 201.
Specifically, as shown in fig. 4, the adjusting mechanism 600 includes a bracket 610 and an adjusting handle 620. The second driving wheel 300 is rotatably connected to the bracket 610, the bracket 610 is swingably disposed on the housing 100, and the adjustment handle 620 is rotatably disposed through the housing 100. When the adjusting handle 620 rotates relative to the housing 100, the adjusting handle 620 abuts against the support 610 and drives the support 610 to swing relative to the housing 100, and the support 610 drives the second driving wheel 300 to approach or depart from the first driving wheel 200, thereby adjusting the size of the feeding channel 201 between the first driving wheel 200 and the second driving wheel 300.
Through the setting, when the line material 20 needs to be changed, the user rotates the adjusting handle 620, the adjusting handle 620 can support and push the support 610, the support 610 overcomes the elastic force swing of the elastic component 700, the support 610 drives the second driving wheel 300 to move towards the direction far away from the first driving wheel 200, the feeding channel 201 between the first driving wheel 200 and the second driving wheel 300 is enlarged, the clamping of the line material 20 is cancelled, and the user changes the line material 20. After the replacement of the thread material 20 is completed, the user rotates the adjusting handle 620, the adjusting handle 620 pushes against the support 610, the support 610 drives the second driving wheel 300 to move towards the direction close to the first driving wheel 200, the feeding channel 201 between the first driving wheel 200 and the second driving wheel 300 is reduced to clamp the thread material 20 so as to convey the thread material 20, and the printing mechanism continues to perform the printing operation.

In this embodiment, the connecting rod 623 is rotatably disposed through the housing 100, and the pushing portion 621 abuts against the bracket 610, wherein the handle 622 has a self-locking position and an opening position on the housing 100. When the handheld portion 622 is switched between the self-locking position and the opening position, the handheld portion 622 can drive the connecting rod 623 to rotate, and further drive the pushing portion 621 to push the bracket 610 to swing in the housing 100, so that the movable rotation of the adjusting handle in the housing is realized.
In one embodiment, referring to fig. 4, the bracket 610 includes a first connecting portion 611 and a second connecting portion 612 connected at an angle. Specifically, the elastic element 700 abuts between one side of the second connecting portion 612 and the housing 100, the adjusting handle 620 abuts against the other side of the first connecting portion 611, the second connecting portion 612 is rotatably mounted above the housing 100, and the second driving wheel 300 is rotatably disposed on the second connecting portion 612. When the adjusting handle 620 stops against the first connecting portion 611, the second connecting portion 612 connected to the first connecting portion 611 in an angle rotates in the housing 100 to drive the second driving wheel 200 to rotate synchronously around the rotation center of the second connecting portion 612, and meanwhile, the elastic component 700 deforms to generate an elastic restoring force, so that the second driving wheel 300 is better close to or away from the first driving wheel 200, and the purpose of reducing or increasing the feeding channel 201 is achieved. Through the arrangement, the structure of the support 610 is simplified, and the pushing part 621 and the support 610 can be pushed effectively.
In this embodiment, the first connecting portion 611 includes two connecting plates disposed in parallel and spaced apart, the second driving wheel 300 is rotatably disposed between the two connecting plates, and the second connecting portion 612 is disposed perpendicularly to the two connecting plates and connected to the two connecting plates. Through setting up second drive wheel 300 in the space that two connecting plates and second connecting portion 612 formed for second drive wheel 300 installs more conveniently, firm, also makes second connecting portion 612 stress balance simultaneously, makes the rotation process of support 610 more reliable and more stable.
In some embodiments, the pushing portion 621, the handle portion 622 and the connecting rod 623 are integrally formed, and have high mechanical strength and good integrity. In other embodiments, the pushing portion 621, the holding portion 622 and the connecting rod 623 may also be a separate structure and connected by riveting or welding.
Further, as shown in fig. 3 and 4, a gap 101 is formed on the housing 100, and the gap 101 partially penetrates through one side of the housing 100 to form a first blocking portion 110 and a second blocking portion 120. When the adjustment handle 620 is switched back and forth between the self-locking position and the opening position, the first stopper 110 and the second stopper 120 can limit the rotation angle of the connection lever 623.
It will be appreciated that when the handle is in the self-locking position, as shown in fig. 3, the bracket 610 is in the initial state, and one end of the connecting rod 623 near the handle 622 abuts against the first blocking portion 110. When the adjusting handle 620 is driven to rotate clockwise (i.e., in the Y direction shown in fig. 3), the end of the connecting rod 623 close to the handle 622 is far away from the first blocking portion 110, and the pushing portion 621 pushes the support 610 upward, so that the support 610 swings counterclockwise (i.e., in the X direction shown in fig. 3) against the elastic force of the elastic component 700, and the feeding channel 201 between the first driving wheel 200 and the second driving wheel 300 is increased; until the adjustment handle 620 rotates 90 degrees clockwise to make the handle 622 in the open position, at this time, one end of the connecting rod 623 close to the pushing portion 621 abuts against the second blocking portion 120, and the second blocking portion 120 can limit the adjustment handle 620 to continue rotating clockwise.
Correspondingly, as shown in fig. 3, if the adjusting handle 620 is driven to rotate 90 degrees in the counterclockwise direction (i.e. the X direction shown in fig. 3), and then the adjusting handle 620 is released, since the elastic component 700 needs to return to its original state and will push the support 610, the support 610 swings clockwise (i.e. the Y direction shown in fig. 3), and further the feeding channel 201 between the first driving wheel 200 and the second driving wheel 300 is reduced until the handheld portion 622 returns to the self-locking position, the first driving wheel 200 and the second driving wheel 300 clamp the wire 20 to feed the wire 20, and the printing mechanism continues to perform the printing operation.
With this arrangement, the first stopper 110 and the second stopper 120 can restrict the rotation limit position of the connecting rod 623; through rotating adjustment handle 620, can order about second drive wheel 300 and be close to or keep away from first drive wheel 200, and need not the user and continue to have improved user's experience effect to adjustment handle 620 application of force.
