Detailed Description

The utility model is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the utility model and are not limiting of the utility model. It should be noted that, for convenience of description, only the portions related to the utility model are shown in the drawings.

It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.

Referring to at least fig. 1-9, an example of the present utility model provides a scissor mechanism 100 including a scissor assembly 11, a first coupling assembly 12, and a second coupling assembly 13.

The first connecting assembly 12 is located between the scissors assembly 11 and the second connecting assembly 13, and connects the two. The second connection assembly 13 may be connected to the left or right side of the housing of the head 200 of the computerized embroidery machine, and the second connection assembly 13 may be connected to the left or right side of the needle bar frame 21 of the head 200 of the computerized embroidery machine.

As shown in fig. 1 and 2, the second connecting component 13 is connected to the right side of the needle bar frame 21 of the machine head 200, so that the rope shearing mechanism 100 is hung on the right side of the machine head 200 of the computerized embroidery machine.

In the related art, if the string cutting mechanism 100 is connected to the housing side of the handpiece, the looper moves together with the needle bar frame 21. When the machine head is a 9-needle machine head, if any one of the machine needles from the number 4 to the number 9 is embroidered, the rope between the looper wheel and the scissor assembly 11 is too long, the tensioning force of the rope is too large, or the rope between the looper wheel and the scissor assembly 11 is interfered with an upper thread clamp at the lower end of the needle bar frame. And cut rope mechanism 100 and connect on needle bar frame 21, cut rope mechanism 100 and can remove in left and right directions along with needle bar frame 21, if any one of No. 4 to 9 machine needles embroidered, the rope length between the looper wheel and the scissors subassembly 11 can not overlength, has avoided the rope to hold in the palm on the cloth to the tensioning force of rope is suitable, has avoided the upper thread clamp mutual interference of rope and needle bar frame lower extreme between looper wheel and the scissors subassembly 11.

The following embodiment describes the use of the thread cutting mechanism 100 as a plug-in to the right side of the head 200 of the computerized embroidery machine:

As shown in fig. 6 to 9, the scissors assembly 11 includes a first telescopic member 116, a rope clamping member 113, a movable blade 112, and a fixed blade 111. The movable blade 112 is movably connected with the fixed blade 111, and the movable blade 112 is close to or far from the fixed blade 111 and has a rope cutting position and an initial position. The rope clamping piece 113 is provided with a rope clamping part 1131 positioned above the movable knife 112, and when the movable knife 112 is positioned at the rope shearing position, the rope clamping part 1131 is matched with the movable knife 112 so as to press the rope between the two parts. The first telescopic member 116 reciprocates in the horizontal direction to switch the movable blade 112 between the rope cutting position and the initial position.

In practical application, as shown in fig. 6 or 8, the scissors assembly 11 includes a fixed blade 111, a movable blade 112, a rope clamping member 113, a pressing plate 114, a movable blade holder 115, a first telescopic member 116, and a bending plate 117.

The stationary blade 111 is connected to the front side of the movable blade holder 115. The movable blade holder 115 is provided with a chute (not shown) extending in the front-rear direction, the movable blade 112 is disposed in the chute, the movable blade 112 is slidably engaged with the chute, and the movable blade 112 reciprocates in the front-rear direction along the chute. Thus, the movable knife 112 can approach the fixed knife 111 until the movable knife 112 and the fixed knife 111 are matched to cut off the rope, and the position of the movable knife 112 at the current moment is the rope cutting position, as shown in fig. 7. The moving blade 112 may be far away from the fixed blade 111 until the moving blade 112 is at a preset position of the chute and is stationary, and at the current moment, the position of the moving blade 112 is an initial position, as shown in fig. 9. The first telescopic piece 116 is connected with the movable blade 112 through a bending plate 117, and the movable blade 112 is reciprocated in the front-rear direction by the first telescopic piece 116. The first telescoping member 116 may be an electric push rod, a pneumatic push rod, a hydraulic push rod, or the like.

The rope clamping member 113 is connected to the upper side of the movable blade holder 115. The rope clamping member 113 is provided with a rope clamping portion 1131, and the rope clamping portion 1131 is located above the stationary blade 111. In the vertical direction, a gap exists between the movable blade 112 and the rope clamping portion 1131. The size of the gap is equal to the diameter of the rope or the gap is slightly smaller than the diameter of the rope.

When the movable blade 112 is in the initial position, as shown in fig. 9, the rope is positioned in the gap between the movable blade 112 and the fixed blade 111. When the movable blade 112 is switched from the initial position to the rope cutting position, as shown in fig. 7, the rope is cut and simultaneously the rope is clamped between the movable blade 112 and the rope clamping portion 1131. Thus, after one pattern is embroidered, the rope is prevented from being separated from the looper of the rope embroidering device or from other mechanisms of the rope embroidering device until the next pattern is embroidered, the rope is embroidered on the cloth, and the movable knife 112 is driven to be staggered with the rope clamping part 1131 under the action of the first telescopic piece 116, so that the clamped rope is loosened, and a new pattern rope embroidering is performed.

In addition, the pressing plate 114 is connected to the upper side of the movable blade holder 115, and the pressing plate 114 is located above the front end of the chute, and the pressing plate 114 spans the chute, that is, the pressing plate 114 limits and constrains the degree of freedom of the movable blade 112 in the upward direction, so that the movable blade 112 moves in the front-rear direction.

As an implementation, the movable blade 112 includes a movable blade edge 1122, and the movable blade edge 1122 extends in a direction perpendicular to a direction from the movable blade 112 to the fixed blade 111, and the rope clamping portion 1131 is provided in parallel with the movable blade edge 1122.

As shown in fig. 7 or 9, the movable blade 112 has a blade inclined surface 1121, and a movable blade edge 1122 and a movable blade back 1123 are provided on the blade inclined surface 1121 so as to be opposed to each other. The movable blade 1122 extends in the left-right direction, and the rope clamping portion 1131 extends in the left-right direction. The length of the cord grip 1131 may be equal to the length of the moving blade edge 1122, or the length of the cord grip 1131 may be slightly less than the length of the moving blade edge 1122. This helps to increase the probability that the sheared rope is caught between the movable blade 112 and the rope catching portion 1131.

Further, when the movable blade 112 is in the rope cutting position, the surface of the rope clamping portion 1131, which is arranged on the same side as the blade inclined surface 1121, is projected on the blade inclined surface 1121, and the projection of the surface of the rope clamping portion 1131, which is arranged on the same side as the blade inclined surface 1121, is positioned on the blade inclined surface 1121.

As shown in fig. 7 or 9, the length of the string clamping portion 1131 is slightly smaller than the length of the movable blade edge 1122. With the movable blade 112 in the rope cutting position, the surface of the rope clamping portion 1131 facing the front side is projected on the blade inclined surface 1121, and the projection of the surface of the rope clamping portion 1131 facing the front side is entirely located on the blade inclined surface 1121. For example, the projection of the surface of the cord grip 1131 toward the front side may coincide with the movable blade edge 1122, or the projection of the surface of the cord grip 1131 toward the front side may coincide with the movable blade back 1123.

Preferably, as shown in fig. 7, the projection of the surface of the string clamping portion 1131 facing the front side is located between the movable blade back 1123 and the movable blade edge 1122, and the distance between the surface of the string clamping portion 1131 facing the front side and the movable blade edge 1122 in the front-rear direction is d,0 mm≤d≤2 mm. By the arrangement, on one hand, the probability that the sheared rope is clamped between the movable knife 112 and the rope clamping part 1131 is increased, and on the other hand, the flexibility that the movable knife 112 is switched from the rope shearing position to the initial position due to the fact that the rope is clamped between the movable knife 112 and the rope clamping part 1131 is avoided.

As an implementation manner, in the vertical direction, a gap exists between the rope clamping portion 1131 and the movable blade 112, and the gap is adjustable.

In practical application, considering the pattern effect of the rope embroidery, ropes with different diameters are selected, so that the acting force of clamping the ropes between the rope clamping portion 1131 and the movable knife 112 is proper, and the excessive or insufficient effect of clamping the ropes is avoided.

Based on this, the rope clamp 113 is detachably attached to the upper side of the movable blade holder 115. The rope clamping member 113 can be connected to the upper side of the movable cutter seat 115 through a fastener, and the gap size between the rope clamping portion 1131 and the movable cutter 112 in the vertical direction can be adjusted by replacing different types of rope clamping members 113, or the rope clamping member 113 is sleeved on the fastener, the fastener rotates positively or reversely, and the gap size between the rope clamping portion 1131 and the movable cutter 112 in the vertical direction can be adjusted.

Of course, it is understood that there may be other ways to adjust the gap size between the clamping cord portion 1131 and the movable blade 112 in the vertical direction, which is not illustrated in the present embodiment.

As an implementation manner, the movable blade 1122 of the scissors assembly 11 extends in the left-right direction and extends in the horizontal direction, and a distance between the movable blade 1122 and the platen in the vertical direction is 1mm to 2mm. The arrangement of the method is beneficial to shortening the length of the residual rope ends on the rope embroidered patterns, avoids the influence on the quality of embroidery caused by overlong residual rope ends, further avoids the need of manually trimming the residual rope ends, and is beneficial to improving the embroidery effect and reducing the production cost.

As an achievable, the first linkage assembly 12 moves the scissor assembly 11 in a front-to-back direction. Wherein the first connecting component 12 and the scissors component 11 are positioned between the machine heads and the bedplate, and the arrangement avoids that the first connecting component 12 and the scissors component 11 occupy the space on the left side or the right side of the machine heads, so that the gap between two adjacent machine heads can be reduced.

As shown in fig. 3-5, the first connecting component 12 includes a first supporting frame 121, a first sliding rail 123, a first sliding block 122, a second supporting frame 124, and a second telescopic member 125. The second telescoping member 125 is identical to the first telescoping member 116.

The second telescopic member 125 is connected to the second supporting frame 124, and the power output end of the second telescopic member 125 makes the first supporting frame 121 reciprocate in the front direction. The first supporting frame 121 is connected to the movable blade holder 115 of the scissor assembly 11.

The second telescopic member 125 is provided to reciprocate the scissors assembly 11 in the front-rear direction, to move forward to approach the needle for thread cutting, and to move backward to be away from the needle for preventing the scissors assembly 11 from interfering with other structures of the string embroidery device. The first sliding block 122 and the first sliding rail 123 have a limiting or guiding function on the movement of the first supporting frame 121, so that the first supporting frame 121 moves along the front-back direction.

As an implementation, the third telescopic member 132 reciprocates the scissors assembly 11 in a vertical direction, or reciprocates the scissors assembly 11 in a direction inclined from the vertical direction. Wherein the third telescoping member 132 is located on either the left or right side of the handpiece.

As shown in fig. 3 to 5, the second connecting assembly 13 includes a third supporting frame 131, a second sliding rail 133, a second sliding block 134, a first connecting member 135, a third telescopic member 132 and a second connecting member 136. The third telescoping member 132 is identical to the first telescoping member 116.

The second slide rail 133 is slidably engaged with the second slider 134. One of the second slide rail 133 and the second slider 134 is connected to the third support 131. The extending direction of the second sliding rail 133 is inclined relative to the setting direction. The power output end of the third telescopic member 132 is connected to the second supporting frame 124, so as to implement the height adjustment of the first connecting assembly 12 in the vertical direction.
