Description

Technical Field

[0001] The present application relates to the technical field of tufting equipment, and in particular to a tufting equipment. Background Art

[0002] Tufting is a commonly used carpet textile process, which uses the reciprocating motion of a needle to drive the wool thread to be implanted into the base fabric, and then uses scissors to cut the wool thread to form a plush effect on the base fabric. However, in the tufting equipment of the related art, after the needle drives the wool thread to be implanted into the base fabric, the scissors have not yet cut the wool thread, and the needle may have pulled the wool thread out of the base fabric again, affecting the quality and efficiency of tufting, or the position where the scissors cut the wool thread is too far from the base fabric, resulting in too long wool thread remaining on the base fabric, affecting the effect of the tufted product. Summary of the invention

[0003] The embodiment of the present application discloses a tufting device, which aims to ensure that the cutting piece can cut off the wool yarn embedded in the base cloth in time, control the length of the wool yarn, and improve the tufting quality and efficiency.

[0004] In order to achieve the above object, the present application discloses a tufting device, comprising:

[0005] Mounting frame;

[0006] A driving mechanism, arranged on the mounting frame;

[0007] A first sliding member, slidably connected to the mounting frame, and drivingly connected to the driving mechanism;

[0008] A second sliding member, slidably connected to the mounting frame, and drivingly connected to the driving mechanism;

[0009] a tufting member connected to the first sliding member;

[0010] a cutting member connected to the second sliding member; and

[0011] The driving mechanism can drive the first sliding member and the second sliding member to slide at a first sliding stroke per unit time and a second sliding stroke per unit time respectively, so as to drive the tufting member and the cutting member to slide, and the first sliding stroke is smaller than the second sliding stroke.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] A tufting device provided by an embodiment of the present application is configured to drive a first sliding member and a second sliding member to be connected to the same driving mechanism so that the driving mechanism can simultaneously drive the first sliding member and the second sliding member to slide, thereby driving the tufting member provided on the first sliding member and the cutting member provided on the second sliding member to slide relative to the mounting frame, so that the tufting member can slide to the working area to implant the wool yarn into the base fabric, and the cutting member can slide to the working area to cut the wool yarn. In addition, since the first sliding stroke of the first sliding member in a unit time is smaller than the second sliding stroke of the second sliding member in a unit time, after the first sliding member drives the tufting member to slide out to implant the wool yarn into the base fabric, when the first sliding member continues to drive the tufting member to slide back, when the tufting member slides a shorter distance, the second sliding member has driven the cutting member to slide a longer distance to reach the working area, thereby ensuring that the cutting member cuts off the wool yarn before the tufting member pulls the wool yarn back, and at the same time controls the length of the cut wool yarn, thereby improving the tufting quality and efficiency.

[0032] The technical solution of the present application will be further described below in conjunction with embodiments and drawings.

[0033] See also Figures 1 to 5 The present application provides a tufting device, including a mounting frame 11, a driving mechanism 12, a first sliding member 13, a second sliding member 14, a tufting member 15 and a cutting member 16. The driving mechanism 12 is arranged on the mounting frame 11, the first sliding member 13 is slidably connected to the mounting frame 11 and is transmission-connected to the driving mechanism 12, the second sliding member 14 is slidably connected to the mounting frame 11 and is transmission-connected to the driving mechanism 12, the tufting member 15 is connected to the first sliding member 13, and the cutting member 16 is connected to the second sliding member 14. The driving mechanism 12 can drive the first sliding member 13 and the second sliding member 14 to slide with a first sliding stroke per unit time and a second sliding stroke per unit time, respectively, so as to drive the tufting member 15 and the cutting member 16 to slide, and the first sliding stroke is parallel to the second sliding stroke.

[0034] The first slide 13 and the second slide 14 are driven to slide by the driving mechanism 12, thereby driving the tufting piece 15 provided on the first slide 13 and the cutting piece 16 provided on the second slide 14 to slide relative to the mounting frame 11, so that the tufting piece 15 can slide to the working area to implant the wool yarn into the base fabric, and the cutting piece 16 can slide to the working area to cut the wool yarn. The first slide 13 and the second slide 14 are driven by the same driving mechanism, which is conducive to controlling the size of the tufting equipment and realizing the miniaturized design of the tufting equipment. At the same time, the synchronization of the activities of the first slide 13 and the second slide 14 is ensured, so that the second slide 14 slides to the working area to cut the wool yarn after the tufting piece 15 on the first slide 13 implants the wool yarn into the base fabric, and there is no conflict in the travel between the first slide 13 and the second slide 14.

[0035] In addition, since the first sliding stroke of the first sliding member 13 is smaller than the second sliding stroke of the second sliding member 14 per unit time, after the first sliding member 13 drives the tufting member 15 to slide out to implant the wool yarn into the base fabric, when the first sliding member 13 drives the tufting member 15 to continue to slide back, when the sliding distance of the tufting member 15 is short, the second sliding member 14 has driven the cutting member 16 to slide a longer distance to reach the working area, ensuring that the cutting member 16 can cut off the wool yarn before the tufting member 15 pulls back the wool yarn, thereby ensuring the tufting efficiency, and at the same time being able to control the length of the cut wool yarn and improve the tufting quality.

[0036] In an optional embodiment, the driving mechanism includes a driving member 121 and a transmission member 17, the transmission member 17 is rotatably connected to the mounting frame 11 and is transmission-connected to the driving member 121, the first sliding member 13 and the second sliding member 14 are transmission-connected to the transmission member 17 respectively, the driving member 121 can drive the transmission member 17 to rotate, and the transmission member 17 drives the first sliding member 13 and the second sliding member 14 to slide, so as to drive the tufting member 15 and the cutting member 16 to slide.

[0037] It can be understood that the first sliding member 13 and the second sliding member 14 can be driven to slide relative to the mounting frame simultaneously by rotating the transmission member 17. By controlling the connection relationship between the first sliding member 13, the second sliding member 14 and the transmission member 17, the sliding stroke of the first sliding member 13 and the second sliding member 14 per unit time can be adjusted.

[0038] Further, the first sliding member 13 and the second sliding member 14 are respectively located on opposite sides of the transmission member 17 along the direction of its own rotation axis, and the transmission member 17 is slidably and rotatably connected to the first sliding member 13 and the second sliding member 14. The driving mechanism 12 is used to drive the transmission member 17 to rotate, so that the transmission member 17 drives the first sliding member 13 and the second sliding member 14 to slide respectively, thereby driving the tufting member 15 and the cutting member 16 to slide.

[0039] It can be understood that the first sliding member 13 and the second sliding member 14 are respectively located on opposite sides of the transmission member 17 along its rotation axis direction, so that the transmission member 17 can slide at the same time and can be rotatably connected to the first sliding member 13 and the second sliding member 14, so that the same transmission member 17 drives the first sliding member 13 and the second sliding member 14 to slide, thereby realizing structural reuse, reducing the size of the tufting equipment, and realizing a miniaturized design.

[0040] Specifically, the transmission member 17 is slidably and rotatably connected to the first sliding member 13, so that when the driving mechanism 12 drives the transmission member 17 to rotate, the transmission member 17 can rotate and slide relative to the first sliding member 13, so as to drive the first sliding member 13 to slide relative to the mounting frame 11, thereby realizing the sliding of the tufting member 15. The transmission member 17 is slidably and rotatably connected to the second sliding member 14, so that when the driving mechanism 12 drives the transmission member 17 to rotate, the transmission member 17 can rotate and slide relative to the second sliding member 14, so as to drive the second sliding member 14 to slide relative to the mounting frame 11, thereby realizing the sliding of the cutting member 16.

[0041] It is worth noting that the first sliding member 13 drives the tufting member 15 to slide relative to the mounting frame 11, and the second sliding member 14 drives the cutting member 16 to slide relative to the mounting frame 11. The tufting member 15 and the cutting member 16 slide alternately to the working area, so that after the tufting member 15 implants the wool yarn into the base fabric, the cutting member 16 can cut the wool yarn. Exemplarily, the tufting device may have a relative working side and a non-working side, and the transmission member 17 can rotate under the drive of the driving mechanism 12, driving the first sliding member 13 and the tufting member 15 thereon to slide from the non-working side to the working side, and driving the second sliding member 14 and the cutting member 16 thereon to slide from the working side to the non-working side, or the transmission member 17 can rotate under the drive of the driving mechanism 12, driving the first sliding member 13 and the tufting member 15 thereon to slide from the working side to the non-working side, and driving the second sliding member 14 and the cutting member 16 thereon to slide from the non-working side to the working side.

[0042] In some embodiments, both the first sliding member 13 and the second sliding member can slide along the first direction relative to the mounting frame 11. When the first sliding member 13 drives the tufting member 15 to slide along the positive direction of the first direction, the second sliding member 14 drives the cutting member 16 to slide along the opposite direction of the first direction. When the first sliding member drives the tufting member 15 to slide along the opposite direction of the first direction, the second sliding member 14 drives the cutting member 16 to slide along the positive direction of the first direction.

[0043] Exemplarily, the positive direction of the first direction is as follows Figure 4 As shown in the Y0 direction in FIG. 1 , the first sliding member 13 or the second sliding member 14 can slide along the positive direction of the first direction to slide from the non-working side to the working side, and the reverse direction of the first direction is as shown in FIG. Figure 4As shown in the Y1 direction in FIG. 1 , the first sliding member 13 or the second sliding member 14 can slide in the opposite direction of the first direction to slide from the working side to the non-working side. By making the first sliding member 13 and the second sliding member 14 reciprocate relative to the mounting frame 11 in the first direction, it is beneficial to control the size of the tufting device in a direction perpendicular to the first direction, thereby realizing a miniaturized design of the tufting device.

[0044] In some embodiments, the first direction is perpendicular to the rotation axis direction of the transmission member 17 .

[0045] Of course, in other embodiments, the first sliding member 13 may also slide relative to the mounting frame 11 along the first direction, and the second sliding member 14 may slide relative to the mounting frame 11 along the second direction, and the second direction is inclined relative to the first direction.

[0046] In some embodiments, the mounting frame 11 includes a guide member 111 , which can extend along a first direction, and the first slider and the second slider are slidably connected to the guide member 111 .

[0047] Further, there are at least four guide members 111, of which two guide members 111 are located on one side of the transmission member 17 along the direction of its own rotation axis, and the two guide members 111 are spaced apart in a direction perpendicular to the first direction, and the opposite sides of the first slider are respectively slidably connected to the two guide members 111. The other two guide members 111 are located on the other side of the transmission member 17 along the direction of its own rotation axis, and the two guide members 111 are spaced apart in a direction perpendicular to the first direction, and the opposite sides of the second slider are respectively slidably connected to the two guide members 111, so as to ensure the activity stability of the first slider and the second slider.

[0048] like Figure 3 , Figure 5 and Figure 6As shown, in some embodiments, the first sliding member 13 is provided with a first slide groove 132a, and the second sliding member 14 is provided with a second slide groove 142a. The transmission member 17 is provided with a first connecting shaft 171 and a second connecting shaft 172, the first connecting shaft 171 is slidably and rotatably connected to the first slide groove 132a, and the second connecting shaft 172 is slidably and rotatably connected to the first slide groove 132a. It can be understood that the first connecting shaft 171 abuts against the inner wall surface of the first slide groove 132a. When the transmission member 17 rotates, the first connecting shaft 171 can push the first sliding member 13 to slide relative to the mounting frame 11, and can rotate and slide relative to the first slide groove 132a under the action of the driving force. The second connecting shaft 172 abuts against the inner wall surface of the second slide groove 142a. When the transmission member 17 rotates, the second connecting shaft 172 can push the second sliding member 14 to slide relative to the mounting frame 11, and can rotate and slide relative to the second slide groove 142a under the action of the driving force. The first connecting shaft 171 is slidably and rotatably connected to the first slide groove 132a, and the second connecting shaft 172 is slidably and rotatably connected to the first slide groove 132a, which is beneficial to simplify the connection structure between the transmission member 17 and the first slider, and the transmission member 17 and the second slider, and control the size of the tufting equipment.

[0049] The first connecting shaft 171 and the second connecting shaft 172 are eccentrically arranged relative to the rotation axis of the transmission member 17 .

[0050] like Figure 6 As shown, further, a first bearing 171a is provided on the outer periphery of the first connecting shaft 171, and the first connecting shaft 171 is slidably and rotatably connected to the first slide groove 132a through the first bearing 171a, and / or a second bearing 172a is provided on the outer periphery of the second connecting shaft 172, and the second connecting shaft 172 is slidably and rotatably connected to the second slide groove 142a through the second bearing 172a. By providing the first bearing 171a and the second bearing 172a, it is convenient for the first connecting shaft 171 to rotate relative to the first slide groove 132a, and the second connecting shaft 172 to rotate relative to the second slide groove 142a, thereby reducing wear and improving the operating efficiency of the tufting equipment.

[0051] Of course, in other embodiments, the first sliding member 13 may be provided with a first sliding groove 132a, and the second sliding member 14 may be provided with a second sliding groove 142a. One end of the first slider may be slidably connected to the first sliding groove 132a of the first sliding member 13, and the other end may be rotatably connected to the transmission member 17, and one end of the second slider may be slidably connected to the second sliding groove 142a of the second sliding member 14, and the other end may be rotatably connected to the transmission member 17, so that the transmission member 17 slides and is rotatably connected to the first sliding member 13 and the second sliding member 14.

[0052] like Figure 4 and Figure 5As shown, in some embodiments, the first sliding member 13 includes a first sliding portion 131 and a second sliding portion 132, the first sliding portion 131 is slidably connected to the mounting frame 11, the second sliding portion 132 is located between the first sliding portion 131 and the transmission member 17 and connected to the first sliding portion 131, and the second sliding portion 132 is provided with a first slide groove 132a on the side facing the transmission member 17, and / or, the second sliding member 14 includes a third connecting portion and a fourth connecting portion, the third connecting portion is slidably connected to the mounting frame 11, the fourth connecting portion is located between the third connecting portion and the transmission member 17 and connected to the third connecting portion, and the fourth connecting portion is provided with a second slide groove 142a on the side facing the transmission member 17. The first sliding portion 131 is slidably connected to the mounting frame 11, the second sliding portion 132 is provided with the first slide groove 132a, which is more conducive to the setting of the first slide groove 132a, the third sliding portion 141 is slidably connected to the mounting frame 11, and the fourth sliding portion 142 is provided with the second slide groove 142a, which is more conducive to the setting of the second slide groove 142a.

[0053] For example, Figure 4 As shown, the first sliding part 131 is slidably connected to the guide member 111, the second sliding part 132 is located between the first sliding part 131 and the transmission member 17, and the second sliding part 132 can extend in a direction perpendicular to the sliding direction of the first sliding member 13, and even the second sliding part 132 can be partially protruded from the first sliding part 131, so as to form a long strip of the first sliding groove 132a and control the overall size of the first sliding member 13. Similarly, the third sliding part 141 and the fourth sliding part 142 are arranged to facilitate the formation of the long strip of the second sliding groove 142a and control the overall size of the second sliding member 14.

[0054] For example, the hardness of the second sliding part 132 and the fourth connecting part can be greater than the hardness of the first sliding part 131 and the third connecting part, thereby ensuring the wear resistance of the first slide groove 132a and the second slide groove 142a and extending the service life of the tufting equipment. For example, the first sliding part 131 and the third connecting part can be made of plastic material, and the second sliding part 132 and the fourth connecting part can be made of metal material.

[0055] In an optional embodiment, the distances between the first connecting shaft 171, the second connecting shaft 172 and the rotation axis of the transmission member 17 can be adjusted so that the distance between the first connecting shaft 171 and the rotation axis of the transmission member 17 is smaller than the distance between the second connecting shaft 172 and the rotation axis of the transmission member 17, so as to control the sliding stroke of the first sliding member 13 and the second sliding member 14 per unit time.

[0056] like Figure 7As shown, in another optional embodiment, the first slide groove 132a and the second slide groove 142a are both long strip grooves, and the angle between the length direction of the first slide groove 132a and the sliding direction of the first sliding member 13 is greater than the angle between the length direction of the second slide groove 142a and the sliding direction of the second sliding member 14, so that the first sliding stroke of the first sliding member 13 per unit time is less than the second sliding stroke of the second sliding member 14.

[0057] It is worth noting that the angle between the length direction of the first slide groove 132a and the sliding direction of the first sliding member 13 is the minimum angle between the two directions, and the angle is less than or equal to 90°. The angle between the length direction of the second slide groove 142a and the sliding direction of the second sliding member 14 is the minimum angle between the two directions, and the angle is less than or equal to 90°. For example, when viewed along the rotation axis direction of the transmission member 17, for example, along Figure 4 From the Z0 direction in FIG. 1 , the angle between the length direction of the first slide groove 132a and the sliding direction of the first slide member 13 can be as follows: Figure 7 As shown in the direction a1 in FIG. 1 , the angle between the length direction of the second slide groove 142a and the sliding direction of the second slide member 14 can be as follows: Figure 7 As shown in the direction of a2, a1>a2.

[0058] In this embodiment, by adjusting the angle between the length direction of the second slide groove 142a and the sliding direction of the second sliding member 14, the stroke of the first sliding member 13 and the second sliding member 14 can be more effectively controlled, the size of the tufting equipment can be controlled, and the miniaturized design of the tufting equipment can be achieved.

[0059] For example, Figure 7 As shown, the first sliding member 13 has driven the tufting member 15 to slide out of the tufting device, and the tufting member 15 is in a state of implanting the wool yarn into the base cloth. Within a unit time, the driving member 121 can drive the transmission member 17 to continue to rotate 45° clockwise, and the transmission member drives the first sliding member 13 and the tufting member 15 to slide along the Y1 direction relative to the mounting frame 11 and retract them into the tufting device, and the first sliding stroke of the first sliding member 13 can be 1 cm. At the same time, the transmission member drives the second sliding member 14 and the cutting member 16 to slide along the Y0 direction relative to the mounting frame and extend out of the tufting device, and the second sliding stroke of the second sliding member 14 can be 2 cm. The first sliding stroke of the first sliding member 13 is smaller than the second sliding stroke of the second sliding member 14.

[0060] As an optional embodiment, when one of the tufting piece 15 and the cutting piece 16 slides in the positive direction of the first direction, the other slides in the reverse direction of the first direction. The length direction of the first slide groove 132a is perpendicular to the first direction. Figure 7As shown, at this time, the angle between the length direction of the first slide 132a and the first direction is 90°, and the angle between the length direction of the second slide 142a and the first direction when it is not perpendicular to the first direction is smaller than the angle between the length direction of the first slide 132a and the first direction. When the tufting piece 15 and the cutting piece 16 can both slide back and forth along the first direction relative to the mounting frame 11, the length direction of the first slide 132a is perpendicular to the first direction, so that the second sliding stroke of the second sliding piece 14 per unit time can be increased as much as possible, and the miniaturized design of the tufting equipment can be realized.

[0061] Specifically, the angle between the length direction of the second sliding groove 142a and the first direction can be adjusted according to actual conditions, and is not specifically limited here.

[0062] In an optional implementation, a slot is provided on the outer periphery of the transmission member 17 , and the mounting bracket 11 is movably engaged in the slot, so that the transmission member 17 can be rotatably connected to the mounting bracket 11 .

[0063] In another optional embodiment, the tufting device further includes a third bearing 20, the outer ring of the third bearing 20 is connected to the mounting frame 11, and the transmission member 17 is connected to the inner ring of the third bearing 20. The transmission member 17 is rotatably connected to the mounting frame 11 through the third bearing 20, which is conducive to improving the operating efficiency of the tufting device.

[0064] like Figure 6 As shown, further, the mounting frame 11 is provided with a step hole 112 running through the opposite sides thereof, the step hole includes a first cavity and a second cavity, the first cavity has a first opening located on the surface of the mounting frame 11, and a step surface 1121 is formed between the first cavity and the second cavity. The transmission member 17 abuts against the outer periphery of the first opening, and the third bearing 20 is clamped in the second cavity and abuts against the step surface. It can be understood that the transmission member 17 is located on the side of the mounting frame 11 provided with the first cavity, and the transmission member 17 abuts against the outer periphery of the first opening along one side of the rotation axis direction, and the third bearing 20 is located in the second cavity of the mounting frame 11 and abuts against the step surface, which can limit the movement of the transmission member 17 and the third bearing 20 relative to the mounting frame 11 in the direction along the rotation axis of the transmission member 17, and the third bearing 20 is clamped in the second cavity, which can limit the movement of the transmission member 17 and the third bearing 20 relative to the mounting frame 11 in the direction perpendicular to the rotation axis of the transmission member 17. In this way, by realizing the rotational connection between the transmission member 17 and the mounting frame 11, the connection method between the third bearing 20 and the mounting frame 11 is simplified.

[0065] Specifically, the transmission member 17 includes a first clamping portion abutting against the outer periphery of the first opening and a second clamping portion at least partially penetrating the first cavity. The inner ring of the third bearing 20 is clamped between the second clamping portion of the transmission member 17 and a fastener connected to the second clamping portion to achieve clamping of the third bearing 20 and the transmission member.

[0066] like Figure 3 and Figure 4 As shown, in some embodiments, the driving member 121 is transmission-connected to the outer periphery of the transmission member 17 to reserve space on both sides of the transmission member 17 along its rotation axis, so as to facilitate the transmission member 17 to slide and be rotatably connected to the first sliding member 13 and the second sliding member 14.

[0067] Furthermore, the driving mechanism 12 further includes a gear transmission assembly 122, the transmission member 17 is a gear, and the gear transmission assembly 122 is transmission-connected to the driving member 121 and meshes with the driving member 17. The gear transmission method makes the setting of the driving member 121 more free, convenient for adjustment according to actual conditions, and helps to make the structure of the tufting equipment more compact to achieve a miniaturized design.

[0068] Specifically, the transmission member 17 is a helical gear, and the gear transmission assembly 122 is a helical gear transmission assembly 122. By helical meshing between the transmission member 17 and the gear transmission assembly 122, the meshing property between the transmission member 17 and the gear transmission assembly 122 can be ensured, the transmission torque is improved, and it is beneficial to use the same transmission member 17 to drive the first sliding member 13 and the second sliding member 14 to slide.

[0069] like Figures 8 to 10 As shown, in another optional embodiment, the driving mechanism includes a driving member 121 and a transmission assembly 123, the driving member 121 is transmission-connected to the first sliding member 13, the transmission assembly 123 is transmission-connected to the first sliding member 13 and the second sliding member 14, the driving member 121 can drive the first sliding member 13 to slide relative to the mounting frame, and the first sliding member 13 drives the second sliding member 14 to slide relative to the mounting frame through the transmission assembly 123. It can be understood that the first sliding member 13 can also drive the second sliding member 14 to slide, and by realizing the transmission assembly 123 that realizes the transmission connection between the first sliding member 13 and the second sliding member 14, the sliding stroke of the first sliding member 13 and the second sliding member 14 in a unit time can be adjusted.

[0070] For example, Fig.10 As shown, the driving member 121 can also drive the gear to rotate through the gear transmission assembly, and slide and rotatably connect to the first sliding member 13 through the gear, so that the gear drives the first sliding member 13 to slide relative to the mounting frame 11. Alternatively, the driving member 121 can drive the crank to rotate, and the connecting rod is rotatably connected to the crank and the first sliding member 13, so that the crank drives the first sliding member 13 to slide relative to the mounting frame through the connecting rod.

[0071] Further, the first sliding member 13 is provided with a first rack structure 133, and the second sliding member 14 is provided with a second rack structure 143. The transmission assembly 123 includes a first gear 1231 and a second gear 1232. The first gear 1231 is rotatably connected to the mounting frame, the first rack structure 133 and the second rack structure 143 are located on opposite sides of the first gear 1231, the first rack structure 133 is meshed with the first gear 1231, the second gear 1232 is rotatably connected to the mounting frame, the second gear 1232 is connected to the first gear 1231 and is coaxially arranged with the first gear 1231, the second gear 1232 is used to mesh with the first rack structure 133, and the number of teeth of the second gear 1232 is greater than the number of teeth of the first gear 1231.

[0072] Among them, the first gear 1231 is meshed with the first rack structure 133, and the first sliding member 13 can drive the first gear 1231 to rotate when it slides relative to the mounting frame. The first gear 1231 can drive the coaxially arranged second gear 1232 to rotate. Since the rotation speeds of the first gear 1231 and the second gear 1232 are the same, and the number of teeth of the second gear 1232 is greater than the number of teeth of the first gear 1231, under the condition of the same rotation angle, the active stroke of the teeth of the second gear 1232 is longer than the active stroke of the teeth of the first gear 1231, so that the second gear 1232 can drive the second sliding member 14 to slide a longer distance, thereby realizing that the first sliding stroke of the first sliding member 13 is less than the second sliding stroke of the second sliding member 14 per unit time.

[0073] Specifically, Fig. 9 As shown, the first sliding member 13 is provided with a first rack structure 133 on both sides perpendicular to its own sliding direction, the tufting member 15 is located between the two first rack structures 133, the second sliding member 14 is provided with a second rack structure 143 on both sides perpendicular to its own sliding direction, the cutting member 16 is located between the two second rack structures 143, and the first rack structure 133 and the second rack structure 143 on the same side are transmission connected by a first gear 1234 and a second gear 1232, that is, the opposite sides of the first sliding member 13 are transmission connected to the opposite sides of the second sliding member 14 respectively, so as to ensure the transmission stability between the first sliding member 13 and the second sliding member 14.

[0074] like Figure 4 and Figure 5As shown, in some embodiments, the tufting device further includes a third sliding member 19, which is slidably connected to the mounting frame 11, and the third sliding member 19 is transmission-connected to the transmission mechanism 12 or the first sliding member 13. The second sliding member 14 is located between the first sliding member 13 and the third sliding member 19. It can be understood that when the first sliding member 13 and the second sliding member 14 slide in different directions, the center of gravity of the tufting device may be unstable, and the first sliding member 13 and the second sliding member 14 are arranged at intervals, and the first sliding member 13 and the second sliding member 14 are prone to generate a rotation torque when sliding. By adding the third sliding member 19 and making the second sliding member 14 located between the first sliding member 13 and the third sliding member 19, when the first sliding member 13 and the second sliding member 14 slide in different directions, the third sliding member 19 slides synchronously to balance the center of gravity of the tufting device, offset or reduce the rotation torque, and ensure the stability of the tufting device.

[0075] Furthermore, the sliding direction of the first sliding member 13 is the same as the sliding direction of the third sliding member 19 , and opposite to the sliding direction of the second sliding member 14 .

[0076] Exemplarily, the first sliding member 13, the second sliding member 14 and the third sliding member 19 all slide in the first direction, and when the first sliding member 13 and the third sliding member 19 slide in the positive direction of the first direction, the second sliding member 14 slides in the opposite direction of the first direction. In this way, the first sliding member 13, the second sliding member 14 and the third sliding member 19 all slide in the same direction relative to the mounting frame 11, which is beneficial to controlling the overall size of the tufting device and ensuring the stability of the tufting device.

[0077] Specifically, the third sliding member 19 and the first sliding member 13 can be connected by a connecting rod or a connecting plate, so that the first sliding member 13 drives the third sliding member 19 to slide relative to the mounting frame 11, thereby simplifying the structure of the tufting equipment and realizing a miniaturized design of the tufting equipment.

[0078] like Figure 4 , Figure 5 as well as Fig.10 As shown, in some embodiments, the tufting device further includes a guide member, which is disposed on the mounting frame 11. The cutting member 16 includes a first knife arm 161 and a second knife arm 162, wherein the first knife arm 161 is connected to the second sliding member 14, and the second knife arm 162 is movably connected to the first knife arm 161. When the cutting member 16 slides relative to the mounting frame 11, the second knife arm 162 can abut against the guide member, so that the second knife arm 162 rotates relative to the first knife arm 161 under the action of the guide member, and switches from a non-cutting state to a cutting state, or from a cutting state to a non-cutting state. By providing the guide member, the state switching of the cutting member 16 can be automatically realized during the sliding process of the cutting member 16, so as to facilitate the cutting of the cutting member 16.

[0079] Exemplarily, the second blade arm 162 may be rotatably connected to the first blade arm 161, or the second blade arm 162 may be slidably connected to the first blade arm 161, which may be adjusted according to actual conditions.

[0080] Further, the guide member includes a first guide member 181, and the first guide member 181 is arranged on the mounting frame 11. The second blade arm 162 has a first inclined surface 1621. When the second sliding member 14 drives the cutting member 16 to slide relative to the mounting frame 11, the first inclined surface 1621 of the second blade arm 162 can roll with the first guide member 181, so that the second blade arm 162 is closed relative to the first blade arm 161 under the action of the first guide member 181, and switches from a non-cutting state to a cutting state. It can be understood that when the second sliding member 14 drives the cutting member 16 to slide toward the wool thread relative to the mounting frame 11 to cut the wool thread, the first inclined surface 1621 of the second blade arm 162 can roll with the first guide member 181, so that the second blade arm 162 moves relative to the first blade arm 161 to close, so that the cutting member 16 switches from a non-cutting state to a cutting state, and cuts the wool thread.

[0081] It can be understood that when the first inclined surface 1621 abuts against the first guide member 181, the first inclined surface 1621 can be tilted relative to the sliding direction of the second sliding member 14 so that the guide member can provide a force in the sliding direction different from that of the second sliding member 14, so that the second knife arm 162 can move relative to the first knife arm 161 to achieve closing.

[0082] Exemplarily, the first guide member 181 may be a bearing, the inner ring of the first guide member 181 is connected to the mounting frame 11, and the outer ring of the first guide member 181 can roll with the first inclined surface 1621, so that the second blade arm 162 rotates relative to the first blade arm 161 under the action of the outer ring of the first guide member 181 until the two are closed.

[0083] In another exemplary embodiment, the first guide member 181 can also be rotatably connected to the mounting frame 11, so that the first guide member 181 can roll with the first inclined surface 1621, so that the second blade arm 162 can rotate relative to the first blade arm 161 under the action of the first guide member 181 until the two are closed.

[0084] Further, the guide member includes a second guide member 182, which is arranged on the mounting frame 11 and has a second inclined surface 1821, and the second inclined surface 1821 is inclined relative to the sliding direction of the second sliding member 14. When the second sliding member 14 drives the cutting member 16 to slide relative to the mounting frame 11, the second blade arm 162 can abut against the second inclined surface 1821 and slide relative to the second inclined surface 1821, so that the second blade arm 162 is opened relative to the first blade arm 161 under the action of the first inclined surface 1621, and switches from the cutting state to the non-cutting state. It can be understood that when the second sliding member 14 drives the cutting member 16 to slide relative to the mounting frame 11 to move away from the wool line, the second blade arm 162 can abut against the second inclined surface 1821 and slide relative to the second inclined surface 1821, so that the second blade arm 162 moves relative to the first blade arm 161 to open, and realizes switching from the cutting state to the non-cutting state, so that the cutting member 16 can cut again.

[0085] It can be understood that the second inclined surface 1821 can be tilted relative to the sliding direction of the second sliding member 14, so that when the second inclined surface 1821 abuts against the second knife arm 162, the second inclined surface 1821 can provide a force in the sliding direction different from that of the second sliding member 14, so that the second knife arm 162 can be opened relative to the second inclined surface 1821 knife arm movement.

[0086] Of course, in other embodiments, the second blade arm 162 can also be connected to the first blade arm 161 or the second sliding member 14 through an elastic member. When there is no external force acting on the second blade arm 162, the elastic restoring force of the elastic member is used to drive the second blade arm 162 to move relative to the first blade arm 161 to open, that is, automatically switch to the non-cutting state.

[0087] like Figure 1 and Figure 3 As shown, in some embodiments, the tufting device is a handheld device, which includes a body 21 and a handle 22, the mounting frame 11 is provided on the body 21, and the handle 22 is connected to the body 21. By providing the handle 22, the user can hold the tufting device for tufting, which is convenient for the user to operate.

[0088] Further, the first sliding member 13, the second sliding member 14 and the driving mechanism 12 are located on the body 21, and the rotation output shaft of the driving member 121 is parallel to the sliding direction of the first sliding member 13 and the second sliding member 14. It can be understood that the driving mechanism 12 is located on the non-working side of the tufting device, so that the rotation output shaft of the driving mechanism 12 is parallel to the sliding direction of the first sliding member 13 and the second sliding member 14, which is conducive to moving the center of gravity of the tufting device backward, making it easier for users to hold the tufting device.

[0089] like Figure 2As shown, in some embodiments, the tufting equipment also includes a guide piece 24, which is arranged on the mounting frame. The guide piece 24 is provided with a guide hole, which is used for the wool thread to pass through and guide the movement direction of the wool thread, thereby ensuring the stability of the movement of the wool thread and preventing the wool thread from winding.

[0090] Specifically, the guide piece 24 includes at least two guide parts arranged at intervals, and a connecting part connecting the two guide parts. Each guide part is provided with at least one guide hole. The wool thread can be sequentially passed through the multiple guide holes and then extend to the tufting piece 15.

[0091] The two guide parts may be arranged in sequence along the sliding direction of the tufted piece 15, and the guide holes respectively penetrate the opposite sides of the guide parts in the sliding direction of the tufted piece 15, so that the pile yarn can move with the tufted piece.

[0092] like Figure 4 and Figure 8 As shown, in some embodiments, the tufting device further comprises a support member 23, which is protruding from the mounting frame 11. When the tufting device is working, the support member 23 can be used to support the base fabric, so that the tufting device and the base fabric are kept stable to ensure the tufting effect.

[0093] Specifically, Figure 4 As shown, the support member 23 is provided with an avoidance hole 231 for avoiding the tufting member 15 and the cutting member 16, so that the tufting member 15 and the cutting member 16 can slide relative to the mounting frame 11 and extend out of the avoidance hole 231, so that the tufting member 15 can be used to implant the wool yarn into the base fabric, and the cutting member 16 can cut off the wool yarn implanted into the base fabric.

[0094] In some embodiments, the support member 23 is provided with at least one notch 232, so that the user can observe the movement state of the tufting member 15 and the cutting member 16 through the notch. Figure 3 As shown, a notch 232 is provided on the side of the support member 23 away from the handle along the Z0 - Z1 direction. When the user holds the handle and performs tufting using the tufting equipment, the movement state of the tufting member 15 and the cutting member 16 can be observed through the notch 232 .

The description of the above embodiments is only used to help understand the tufting equipment of the present application and its core idea; at the same time, for general technicians in this field, according to the idea of ​​the present application, there will be changes in the specific implementation method and application scope.
