Abstract
Description
Technical Field
[0001] The utility model generally relates to the technical field of computer embroidery machines, and in particular to a rope cutting mechanism, a rope embroidery device and a computer embroidery machine. Background Art
[0002] In the field of computerized embroidery machines, cording is a common specialty embroidery technique. The vast majority of cords currently available on the market are simple, single-color cords. Before starting, the operator manually wraps and clamps the designated cord around the cording mechanism on each machine head. The machine then starts. After the current pattern is embroidered, the operator manually cuts the cords one by one and clamps the ends of the cords back onto the cording mechanism. This process repeats until the cording is complete.
[0003] In the early days of the computerized embroidery machine industry, the number of machine heads was small, labor costs were low, and manual string threading and cutting had little impact on the production cost of embroidery products. However, with technological advancements, computerized embroidery machines with dozens or even hundreds of machine heads have become commonplace, and labor costs have continued to rise year by year. Manual string threading and cutting results in significant downtime, and the lengths of the strings left behind by manual string cutting vary, requiring extensive manual labor to trim them later. Therefore, designing a new string cutting mechanism that automates string threading and cutting became increasingly necessary. Utility Model Content
[0004] The present application hopes to provide a rope cutting mechanism, a rope embroidery device and a computer embroidery machine, which are at least used for automatic thread cutting and improving the efficiency of rope embroidery.
[0005] The utility model provides a rope cutting mechanism, which is used to be connected to a needle bar frame and can move with the needle bar frame. The rope cutting mechanism comprises a scissors assembly, which comprises a first telescopic member, a rope clamping member, a movable knife and a fixed knife.
[0006] The movable knife is movably connected to the fixed knife. The movable knife has a rope cutting position and an initial position when it approaches or moves away from the fixed knife. The rope clamping member is provided with a rope clamping portion located above the fixed knife. When the movable knife is in the rope cutting position, the rope clamping portion cooperates with the movable knife to clamp the rope between the two.
[0007] The first telescopic member reciprocates in a horizontal direction to switch the movable knife between the rope cutting position and the initial position.
[0008] As an implementation manner, the movable knife has a movable knife blade, the movable knife blade extends in a direction perpendicular to a direction from the movable knife to the fixed knife, and the rope clamping portion is arranged parallel to the movable knife blade.
[0009] As an implementation manner, the blade of the movable knife extends in a horizontal direction.
[0010] As an implementable method, the movable knife has a blade bevel, and the movable knife blade is provided on the blade bevel. When the movable knife is in the rope cutting position, the surface of the rope clamping part arranged on the same side as the blade bevel is projected onto the blade bevel, and the projection of the surface of the rope clamping part arranged on the same side as the blade bevel is located on the blade bevel.
[0011] As an implementable manner, in a direction parallel to the direction from the movable knife to the fixed knife, a distance d between a surface of the rope clamping portion arranged on the same side as the blade slope and the movable knife edge is 0mm≤d≤2mm.
[0012] As an implementation manner, in the vertical direction, there is a gap between the movable blade and the rope clamping portion.
[0013] As an implementation manner, in the vertical direction, there is a gap between the movable blade and the rope clamping portion, and the gap is adjustable.
[0014] As an implementable method, it further includes a second telescopic member and a third telescopic member.
[0015] The second telescopic member enables the scissor assembly to move in the front-to-back direction, the direction from the movable knife to the fixed knife is parallel to the front-to-back direction, and the second telescopic member is located below the head of the computer embroidery machine;
[0016] The third telescopic member enables the scissor assembly to reciprocate in a vertical direction, or enables the scissor assembly to reciprocate in a direction inclined relative to the vertical direction.
[0017] The utility model provides a rope shearing mechanism, comprising the above-mentioned rope shearing mechanism.
[0018] The utility model provides a computer embroidery machine, comprising a machine head, a table and the above-mentioned cord embroidery device, wherein the cord cutting mechanism of the cord embroidery device is located on one side of the machine head. The scissor assembly of the cord cutting mechanism is located between the needle bar frame of the machine head and the table.
[0019] In the vertical direction, the distance between the scissor assembly and the table is adjustable.
[0020] As an achievable manner, the distance between the movable blade of the scissors assembly and the table in the vertical direction is between 1 mm and 2 mm.
[0021] In the above-mentioned scheme, the present application provides a rope clamping portion located above the fixed knife on the rope clamping member. When the movable knife is in the rope-cutting position, the rope clamping portion cooperates with the movable knife to clamp the rope between the two. When the movable knife is in the initial position, the rope is located in the gap between the movable knife and the fixed knife. When the movable knife switches from the initial position to the rope-cutting position, the rope is cut and the rope clamp is located between the movable knife and the rope clamping portion. In this way, after embroidering a pattern, the rope is prevented from detaching from the looping wheel of the rope embroidery device or other mechanisms of the rope embroidery device. Until the next pattern is embroidered, the rope is embroidered on the fabric. Under the action of the first telescopic member, the movable knife drives the movable knife and the rope clamping portion to stagger relative to each other to loosen the clamped rope, thereby embroidering a new pattern. In addition, the scissor assembly moves in the front-to-back direction. At the same time, the distance between the scissor assembly and the table in the vertical direction is adjustable. In this way, the length of the remaining cord ends on the cord-embroidered pattern can be controlled, which avoids the remaining cord ends being too long and affecting the embroidery quality, and further avoids the need for manual trimming of the remaining cord ends, which helps to improve the embroidery effect and reduce production costs.

[0037] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.
[0038] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0039] At least see Figures 1-9 As shown, the present invention provides a rope cutting mechanism 100 , including a scissors assembly 11 , a first connecting assembly 12 and a second connecting assembly 13 .
[0040] The first connecting assembly 12 is located between the scissor assembly 11 and the second connecting assembly 13, and connects the two. The second connecting assembly 13 can be connected to the left or right side of the housing of the head 200 of the computer embroidery machine, and the second connecting assembly 13 can be connected to the left or right side of the needle bar frame 21 of the head 200 of the computer embroidery machine.
[0041] like Figure 1 and Figure 2 As shown, the second connecting assembly 13 is connected to the right side of the needle bar frame 21 of the machine head 200, so that the rope cutting mechanism 100 is externally mounted on the right side of the machine head 200 of the computer embroidery machine.
[0042] It should be noted that in the related art, if the rope cutting mechanism 100 is connected to one side of the machine head housing, the loop wheel and the needle bar frame 21 move together. When the machine head is a 9-needle machine head, if any of the No. 4 to No. 9 needles are embroidering, the rope between the loop wheel and the scissors assembly 11 will be too long, the rope tension will be too large, or the rope between the loop wheel and the scissors assembly 11 will interfere with the upper thread clamp at the lower end of the needle bar frame. However, the rope cutting mechanism 100 is connected to the needle bar frame 21 and can move left and right with the needle bar frame 21. If any of the No. 4 to No. 9 needles are embroidering, the rope between the loop wheel and the scissors assembly 11 will not be too long, thus preventing the rope from being supported on the fabric. In addition, the rope tension is appropriate, thus preventing the rope between the loop wheel and the scissors assembly 11 from interfering with the upper thread clamp at the lower end of the needle bar frame.
[0043] The following embodiment is described by assuming that the rope cutting mechanism 100 is externally mounted on the right side of the head 200 of the computer embroidery machine:
[0044] like Figure 6-Figure 9 As shown, 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 to the fixed blade 111, and has a rope-cutting position and an initial position when the movable blade 112 approaches or moves away from the fixed blade 111. The rope clamping member 113 is provided with a rope-clamping portion 1131 located above the movable blade 112. When the movable blade 112 is in the rope-cutting position, the rope-clamping portion 1131 cooperates with the movable blade 112 to compress the rope between the two. The first telescopic member 116 reciprocates horizontally to switch the movable blade 112 between the rope-cutting position and the initial position.
[0045] In practical applications, such as Figure 6 or Figure 8 As shown, 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 .
[0046] The fixed blade 111 is connected to the front side of the movable blade holder 115. The movable blade holder 115 is provided with a slide groove (not marked) extending in the front-to-back direction. The movable blade 112 is set in the slide groove. The movable blade 112 slides and cooperates with the slide groove, and the movable blade 112 reciprocates in the front-to-back direction along the slide groove. In this way, the movable blade 112 can approach the fixed blade 111 until the movable blade 112 cooperates with the fixed blade 111 to cut the rope. At this moment, the position of the movable blade 112 is the rope cutting position, as shown in FIG. Figure 7 The movable knife 112 can be moved away from the fixed knife 111 until the movable knife 112 is at a preset position of the chute and is stationary. At this moment, the position of the movable knife 112 is the initial position, as shown in FIG. Figure 9The first telescopic member 116 is connected to the movable blade 112 via a bending plate 117, and the first telescopic member 116 enables the movable blade 112 to reciprocate in the front-back direction. The first telescopic member 116 can be an electric push rod, a pneumatic push rod, a hydraulic push rod, etc.
[0047] The rope clamp 113 is connected to the upper side of the movable blade holder 115. It has a rope clamping portion 1131 positioned above the fixed blade 111. A vertical gap exists between the movable blade 112 and the rope clamping portion 1131. The gap is equal to or slightly smaller than the diameter of the rope.
[0048] When the movable knife 112 is in the initial position, as shown in FIG. Figure 9 As shown, the rope is located in the gap between the movable knife 112 and the fixed knife 111. When the movable knife 112 switches from the initial position to the rope cutting position, as shown in FIG. Figure 7 As shown, when the rope is cut, the rope is clamped between the movable knife 112 and the rope clamping part 1131. In this way, when one pattern is embroidered, the rope is prevented from being detached from the looping wheel of the rope embroidery device or other mechanisms of the rope embroidery device. When the rope is embroidered on the fabric, the movable knife 112 is driven by the first telescopic member 116 to stagger with the rope clamping part 1131 to loosen the clamped rope, thereby starting the rope embroidery of the next pattern.
[0049] In addition, the pressure plate 114 is connected to the upper side of the movable knife seat 115, and the pressure plate 114 is located above the front end of the slide groove. The pressure plate 114 is arranged across the slide groove, that is, the pressure plate 114 limits and constrains the upward freedom of the movable knife 112, so that the movable knife 112 moves in the front and back directions.
[0050] As an implementation method, the movable knife 112 has a movable knife blade 1122 , which extends in a direction perpendicular to the direction from the movable knife 112 to the fixed knife 111 , and the rope clamping portion 1131 is arranged parallel to the movable knife blade 1122 .
[0051] like Figure 7 or Figure 9 As shown, the movable blade 112 has an inclined blade surface 1121, on which are disposed opposing movable blades 1122 and a movable blade back 1123. The movable blade 1122 extends in the left-right direction, and the rope clamping portion 1131 also extends in the left-right direction. The rope clamping portion 1131 can be equal in length to the movable blade 1122, or slightly shorter. This helps increase the probability that a cut rope will be trapped between the movable blade 1122 and the rope clamping portion 1131.
[0052] Furthermore, when the movable knife 112 is in the rope cutting position, the surface of the rope clamping portion 1131 arranged on the same side as the blade bevel 1121 is projected onto the blade bevel 1121 , and the projection of the surface of the rope clamping portion 1131 arranged on the same side as the blade bevel 1121 is located on the blade bevel 1121 .
[0053] like Figure 7 or Figure 9 As shown, the length of the rope clamping portion 1131 is slightly shorter than the length of the movable blade 1122. When the movable blade 112 is in the rope-cutting position, the front-facing surface of the rope clamping portion 1131 is projected onto the blade slope 1121, and the projection of the front-facing surface of the rope clamping portion 1131 is completely located on the blade slope 1121. For example, the projection of the front-facing surface of the rope clamping portion 1131 can overlap with the movable blade 1122, or the projection of the front-facing surface of the rope clamping portion 1131 can overlap with the movable blade back 1123.
[0054] Preferably, if Figure 7 As shown, the projection of the front-facing surface of the rope clamping portion 1131 is located between the movable blade back 1123 and the movable blade 1122. Furthermore, the distance d between the front-facing surface of the rope clamping portion 1131 and the movable blade 1122 in the front-to-back direction is 0 mm ≤ d ≤ 2 mm. This arrangement, on the one hand, increases the probability that a cut rope will be trapped between the movable blade 112 and the rope clamping portion 1131, and on the other hand, prevents the flexibility of the movable blade 112 from switching from the rope cutting position to the initial position, which would otherwise be affected by the rope being trapped between the movable blade 112 and the rope clamping portion 1131.
[0055] As an implementation method, in the vertical direction, there is a gap between the rope clamping portion 1131 and the movable knife 112, and the gap is adjustable.
[0056] In actual application, considering the pattern effect of rope embroidery, ropes of different diameters will be selected to ensure that the force of clamping the rope between the rope clamping part 1131 and the movable knife 112 is appropriate to avoid the force of clamping the rope being too large or too small.
[0057] Based on this, the rope clamping member 113 is detachably connected 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 blade holder 115 via a fastener. By replacing a different type of rope clamping member 113, the vertical gap between the rope clamping portion 1131 and the movable blade 112 can be adjusted. Alternatively, the rope clamping member 113 can be mounted on the fastener, and the fastener can be rotated forward or reversed to adjust the vertical gap between the rope clamping portion 1131 and the movable blade 112.
[0058] Of course, it is understandable that there may be other ways to adjust the gap size between the rope clamping portion 1131 and the movable knife 112 in the vertical direction, which are not listed one by one in this embodiment.
[0059] As an implementation, the movable blade 1122 of the scissor assembly 11 extends horizontally and horizontally, with the vertical distance between the movable blade 1122 and the base plate ranging from 1 mm to 2 mm. This arrangement helps to shorten the length of the remaining cord ends on the completed cord embroidery pattern, preventing the remaining cord ends from being too long and affecting the embroidery quality. This further avoids the need for manual trimming of the remaining cord ends, helps improve the embroidery effect, and reduces production costs.
[0060] As an implementation method, the first connecting assembly 12 enables the scissor assembly 11 to move in the front-to-back direction. The first connecting assembly 12 and the scissor assembly 11 are located between the machine head and the table. This arrangement avoids the first connecting assembly 12 and the scissor assembly 11 occupying the space on the left or right side of the machine head, thereby reducing the gap between two adjacent machine heads.
[0061] like Figure 3-Figure 5 As shown, the first connecting assembly 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 telescopic member 125 is the same as the first telescopic member 116.
[0062] A first slide rail 123 and a first slider 122 are sandwiched between the first support frame 121 and the second support frame 124. The first slider 122 slidably engages with the first slide rail 123. One of the first slider 122 and the first slide rail 123 is connected to the first support frame 121, and the other is connected to the second support frame 124. A second telescopic member 125 is connected to the second support frame 124. The power output end of the second telescopic member 125 causes the first support frame 121 to reciprocate in the forward direction. The first support frame 121 is connected to the movable blade holder 115 of the scissors assembly 11.
[0063] The second telescopic member 125 allows the scissor assembly 11 to reciprocate in the forward and backward directions, moving forward toward the needle to trim the thread and backward away from the needle to prevent the scissor assembly 11 from interfering with other structures of the cord embroidery device. The first slider 122 and the first slide rail 123 limit or guide the movement of the first support frame 121, allowing the first support frame 121 to move in the forward and backward directions.
[0064] As an implementation method, the third telescopic member 132 causes the scissor assembly 11 to reciprocate in the vertical direction, or causes the scissor assembly 11 to reciprocate in a direction inclined relative to the vertical direction. Wherein, the third telescopic member 132 is located on the left or right side of the machine head.
[0065] like Figure 3-Figure 5As shown, the second connecting assembly 13 includes a third support frame 131, a second slide rail 133, a second slider 134, a first connecting member 135, a third telescopic member 132 and a second connecting member 136. The third telescopic member 132 is the same as the first telescopic member 116.
[0066] 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 frame 131. The extension direction of the second slide rail 133 is inclined relative to the setting direction. The power output end of the third telescopic member 132 is connected to the second support frame 124 mentioned above to achieve vertical height adjustment of the first connecting component 12. This makes it possible to control the length of the remaining rope ends on the pattern after the rope embroidery is completed, avoiding the remaining rope ends being too long and affecting the quality of the embroidery, thereby avoiding the need for manual trimming of the remaining rope ends, helping to improve the embroidery effect and reduce production costs.
[0067] The second connecting member 136 connects the first connecting member 135 and the third supporting frame 131 , and the first connecting member 135 is connected to the needle bar frame 21 .
[0068] The third telescopic member 132 can be provided to adjust the height of the scissor assembly 11 in the vertical direction, that is, the distance between the scissor assembly 11 and the table of the computer embroidery machine can be adjusted.
[0069] The present invention also provides a cord embroidery device, comprising the cord cutting mechanism 100. The cord embroidery device has the advantages of the cord cutting mechanism 100, so it will not be described in detail.
[0070] like Figure 1 and Figure 2 As shown, the present invention also provides a computerized embroidery machine, comprising a machine head 200, a table, and the aforementioned cord embroidery device. The cord cutting mechanism 100 of the cord embroidery device is located on one side of the machine head 200. The scissor assembly 11 of the cord cutting mechanism 100 is located between the needle bar frame 21 of the machine head 200 and the table. The scissor assembly 11 moves in the front-to-back direction. Furthermore, the vertical distance between the scissor assembly 11 and the table is adjustable. This allows the length of the remaining cord ends on the corded pattern to be controlled, preventing the remaining cord ends from being too long and affecting the quality of the embroidery. This also avoids the need for manual trimming of the remaining cord ends, helping to improve the embroidery effect and reduce production costs.
