As shown in fig. 1-3, scissor mechanism 200 is attached to the right side of the handpiece and cord clamping mechanism 100 is attached to the right side of needle bar carrier 300.
In the related art, the clip cord mechanism 100 is installed at one side of the head, and the looper moves together with the needle bar frame 300. When the machine head is a 9-needle machine head, if any one of the machine needles from No. 4 to No. 9 is embroidered, the rope between the looper and the rope clamping mechanism 100 is too long, the tensioning force of the rope is too large, or the rope between the looper and the rope clamping mechanism 100 is interfered with an upper thread clamp at the lower end of the needle bar frame. The rope clamping mechanism 100 is connected to the needle bar frame 300, the rope clamping mechanism 100 can move along with the needle bar frame 300 in the left-right direction, if any one of the machine needles from the number 4 to the number 9 is embroidered, the length of the rope between the looper wheel and the rope clamping mechanism 100 is not too long, the rope is prevented from being supported on cloth, the tensioning force of the rope is proper, and the mutual interference between the looper wheel and the rope clamping mechanism 100 and the upper thread clamp at the lower end of the needle bar frame 300 is avoided.
As shown in fig. 8 and 9, the scissors mechanism 200 includes a scissors assembly 21, a first connecting assembly 22, a second connecting assembly 23, and a connecting plate 24. The first link assembly 22 includes front and rear telescopic members 221, the front and rear telescopic members 221 allowing the scissors assembly 21 to reciprocate in the front and rear directions, and the second link assembly 23 includes upper and lower telescopic members 231 allowing the scissors assembly 21 to reciprocate in the vertical directions. The upper and lower telescoping members 231 are the same as the front and rear telescoping members 221, and may be electric push rods, hydraulic push rods, pneumatic push rods, or the like.
As shown in fig. 9, the scissors assembly 21 is connected with the first connecting assembly 22 through the connecting plate 24, and the power output end of the front-rear expansion member 221 of the first connecting assembly 22 is connected with the scissors assembly 21, so that the scissors assembly 21 moves forward and backward. The power output end of the up-and-down expansion member 231 of the second connecting assembly 23 is connected with the first connecting assembly 22, so that the first connecting assembly 22 moves up and down, and further the up-and-down movement of the scissors assembly 21 is realized.

Similarly, the second connecting assembly 23 also includes a guide assembly (not shown) for guiding the power output end of the up-down expansion member 231 to move in the up-down direction.
The rear surface (rear-facing surface) of the housing is an inclined surface, so that a slightly larger space is provided behind the housing. When the scissors assembly 21 moves along the front-back direction, the initial position of the scissors assembly 21 is positioned at the rear of the machine shell, so that the space is ingeniously utilized, and the scissors assembly 21 is prevented from occupying the space at the left side or the right side of the machine head. In addition, when the movable knife of the scissors assembly 21 moves along the front-back direction, the movable knife is positioned between the needle bar frame 300 and the bedplate of the computerized embroidery machine, and the height between the scissors assembly 21 and the bedplate can be adjusted through the upper telescopic piece 231 and the lower telescopic piece 231, so that the length of the residual rope ends on the rope embroidered pattern is controllable, the quality of embroidery is prevented from being influenced by the overlong residual rope ends, the need for manually trimming the residual rope ends is avoided, the embroidery effect is improved, and the production cost is reduced.
As shown in fig. 3-7, the rope clamping mechanism 100 includes a rope hooking member 12, a rope clamping seat 11, a first telescopic member 13, a second telescopic member 15 and a connecting member 14.
The rope clamping seat 11 is provided with a sliding groove (not labeled), the sliding groove extends along the left-right direction, and the rope hooking piece 12 is arranged in the sliding groove. The first telescopic member 13 is identical to the second telescopic member 15, and the first telescopic member 13 and the second telescopic member 15 are arranged in parallel and are all arranged along the left-right direction.
As shown in fig. 6 and 7, the power output end of the first telescopic member 13 is connected to the hook string member 12 such that the hook string member 12 reciprocates in the left-right direction. Because the first telescopic member 13 is a single-acting cylinder or a hydraulic cylinder, the first telescopic member 13 enables the rope hooking member 12 to move from right to left under the action of air pressure or hydraulic pressure, and a gap exists between the rope hooking portion 121 of the rope hooking member 12 and the rope clamping portion 111 on the rope clamping seat 11. And the rope may be located at the gap. Under the spring action of the first telescopic piece 13, the rope hooking piece 12 moves from left to right, and the rope hooking portion 121 of the rope hooking piece 12 approaches the rope clamping portion 111 on the rope clamping seat 11 until the rope hooking portion 121 and the rope clamping portion 111 clamp the rope between the rope and the rope.
The power output end of the second telescopic piece 15 is connected with the power output end of the first telescopic piece 13 through the connecting piece 14, the power output end of the second telescopic piece 15 moves from right to left, the power output end of the first telescopic piece 13 can be driven to move from right to left, and then the rope hooking part 121 is staggered with the rope clamping part 111 to loosen the clamped rope.
When the rope embroidering device works, after the rope is sheared by the scissor mechanism 200, the rope is clamped between the rope hooking part 121 of the rope hooking member 12 and the rope clamping part 111 of the rope clamping seat 11. Thus, when one pattern is embroidered, the rope is prevented from being separated from the looper of the rope embroidering device or other mechanisms of the rope embroidering device. The rope is clamped between the hook rope portion 121 and the rope clamping portion 111 under the action of the spring of the first telescopic piece 13, so that the hook rope portion 121 is elastically pressed against the rope, various types of ropes such as cotton ropes, nylon ropes, polyester ropes and hemp ropes are clamped between the hook rope portion 121 and the rope clamping portion 111, excessive clamping force is avoided, the hook rope portion 121 and the rope clamping portion 111 cannot be freely staggered, the glossiness of the rope is prevented from being influenced due to excessive clamping force, and the rope is prevented from being separated from a looper of the rope embroidering device due to the fact that the clamping force is too small. In addition, the rope with different diameters of the same type can be clamped between the rope hooking part 121 and the rope clamping part 111, so that excessive or insufficient clamping force is avoided.
Of course, it will be appreciated that in some embodiments, the hooked cord portion 121 is rigidly pressed against the cord, while the clip cord portion 111 resiliently presses against the cord. Or the hooking portion 121 elastically presses against the rope, and the clamping portion 111 elastically presses against the rope.
After the embroidery of one pattern is finished, until the rope is embroidered into the next pattern, the rope is embroidered on the cloth, and the power output end of the first telescopic piece 13 drives the rope hooking part 121 and the rope clamping part 111 to be staggered mutually under the action of the power output end of the second telescopic piece 15 so as to loosen the clamped rope, thereby carrying out new pattern rope embroidery.
As an implementation, the surface of the hook rope portion 121 contacting the rope is a curved surface, the surface of the clamp rope portion 111 contacting the rope is a plane surface, or
The surface of the hook string portion 121 contacting the string is a plane, and the surface of the string clamping portion 111 contacting the string is a curved surface.
As shown in fig. 4 and 5, the surface contacting the rope on the rope clamping portion 111 is an inclined plane. A cylindrical rod 1211 is welded to the rope hooking portion 121, and the cylindrical rod 1211 is in contact with the rope. Since the area of contact of the cylindrical rod 1211 with the rope is smaller than the area of contact of the inclined plane with the rope, this helps to properly clamp the rope between the cylindrical rod 1211 and the inclined plane, avoiding excessive or insufficient clamping force. In addition, when the inclined plane and the cylindrical rod 1211 clamp the rope, the friction acting force on the rope is small, the influence on the glossiness of the rope is avoided, and the rope embroidery effect of the rope embroidery pattern is guaranteed.
Of course, it is understood that the surface of the hook rope portion 121 contacting the rope may be a curved surface, the surface of the rope clamping portion 111 contacting the rope may be a curved surface, or the surface of the hook rope portion 121 contacting the rope may be a plane, the surface of the rope clamping portion 111 contacting the rope may be a plane, and the "plane" herein may be an inclined plane or a horizontal plane.
As an implementation manner, the rope clamping mechanism 100 further includes a first supporting frame 16, a third telescopic member 17 and a second supporting frame 18.
As shown in fig. 3-7, the third telescoping member 17 may be an electric push rod, a hydraulic push rod, a pneumatic push rod, or the like.
The rope clamping seat 11 is connected to the first supporting frame 16, and the power output end of the third telescopic piece 17 is connected with the first supporting frame 16. The power output end of the third telescopic member 17 reciprocates along the vertical direction or the direction inclined relative to the vertical direction, so that the height of the rope clamping seat 11 in the vertical direction can be adjusted, and the height of the rope clamping seat 11 is matched with the height of the scissors assembly 21 of the scissors mechanism 200, so as to ensure that the two parts cooperate to complete the wire cutting.
A guide component is arranged between the third telescopic piece 17 and the second supporting frame 18, and the guide component is used for guiding the power output end of the third telescopic piece 17 to reciprocate along the vertical direction or the direction inclined relative to the vertical direction. The second support 18 is connected to the right side of the needle bar frame 300.
