Description

Technical Field

[0001] The utility model generally relates to the technical field of computer embroidery machines, and particularly relates to a rope embroidery device and a computer embroidery machine. Background Art

[0002] In the technical field of computer embroidery machines, rope embroidery is a relatively common special embroidery. Most of the embroidery ropes on the current market are single-color simple rope embroideries. Before starting the embroidery, the operator needs to manually wind and clamp the specified type of embroidery rope on the rope embroidery device of each head, and then start the computer embroidery machine. After the current embroidery pattern is embroidered, the operator manually cuts the embroidery rope one by one and clamps the rope end on the rope embroidery device. The above operations are repeated until the rope embroidery operation is completed.

[0003] In the initial stage of the development of the computer embroidery machine industry, the number of heads on the equipment was small and the labor cost was also low. Manual threading and cutting of ropes had little impact on the production cost of embroidered products. However, with the progress of technology, dozens or even hundreds of heads on computer embroidery machines have become common, and the labor cost has been increasing year by year. Manual threading and cutting of ropes will result in a large amount of downtime, and the lengths of the rope ends left by manual cutting are uneven, and a large amount of labor is also required to trim the rope ends later. Therefore, it is particularly necessary to design a new rope cutting mechanism and adopt an automated method for threading and cutting ropes. Summary of the Utility Model

[0004] This application expects to provide a rope cutting mechanism, a rope embroidery device and a computer embroidery machine, at least for automatically cutting the thread to improve the efficiency of rope embroidery.

[0005] The utility model provides a rope embroidery device, including: a rope cutting mechanism.

[0006] The rope cutting mechanism is located on the left or right side of the head of the computer embroidery machine; the rope cutting mechanism includes a pair of scissors components, and the pair of scissors components includes a first telescopic member, a rope pressing member, a moving knife and a fixed knife.

[0007] The moving knife is movably connected to the fixed knife, and the moving knife has a rope cutting position and a rope loosening position when approaching or departing from the fixed knife. The rope pressing member is provided with a rope pressing portion above the fixed knife. When the moving knife is in the rope cutting position, the rope pressing portion cooperates with the moving knife to clamp the rope between the two.

[0008] The first telescopic member reciprocates in the left-right direction to switch the moving knife between the rope cutting position and the rope loosening position.

[0009] As an implementable mode, the moving knife has a moving knife blade, the moving knife blade extends in a direction perpendicular to the direction from the moving knife to the fixed knife, and the rope pressing portion is arranged parallel to the moving knife blade.

[0010] As an implementable mode, the moving knife blade extends in the horizontal direction.

[0011] As an implementable mode, the moving knife has a blade inclined surface, and the moving knife blade is provided on the blade inclined surface. When the moving knife is in the rope-cutting position, the surface of the rope-pressing part arranged on the same side as the blade inclined surface projects on the blade inclined surface, and the projection of the surface of the rope-pressing part arranged on the same side as the blade inclined surface is located on the blade inclined surface.

[0012] As an implementable mode, in the direction parallel to the direction from the moving knife to the fixed knife, the distance between the surface of the rope-pressing part arranged on the same side as the blade inclined surface and the moving knife blade is d, and 0mm ≤ d ≤ 2mm.

[0013] As an implementable mode, there is a gap between the moving knife and the rope-pressing part in the vertical direction.

[0014] As an implementable mode, there is a gap between the moving knife and the rope-pressing part in the vertical direction, and the gap is adjustable.

[0015] As an implementable mode, there are also a second telescopic member and a third telescopic member.

[0016] The second telescopic member enables the scissor assembly to move in the left-right direction;

[0017] The third telescopic member enables the scissor assembly to reciprocate in the vertical direction, or enables the scissor assembly to reciprocate in a direction inclined relative to the vertical direction.

[0018] The present utility model provides a computerized embroidery machine, which includes a machine head, a table board and the above-mentioned rope embroidery device. The rope-cutting mechanism of the rope embroidery device is located on one side of the machine head.

[0019] In the vertical direction, the distance between the scissor assembly of the rope-cutting mechanism and the table board is adjustable, and the scissor assembly moves in the left-right direction.

[0020] As an implementable mode, the distance between the moving knife blade of the scissor assembly and the table board in the vertical direction is between 1mm and 2mm.

[0021] In the above scheme, the present application provides a rope-pressing part located above the fixed knife on the rope clamping part. When the movable knife is in the rope-cutting position, the rope-pressing part cooperates with the movable knife to clamp the rope thread between the two. When the movable knife is in the rope-loosening position, the rope thread is located in the gap between the movable knife and the fixed knife. When the movable knife switches from the rope-loosening position to the rope-cutting position, the rope thread is cut and the rope thread clamp is arranged between the movable knife and the rope-pressing part. In this way, after embroidering a pattern, the rope thread is prevented from being separated from the loop wheel of the rope embroidery device, or from other mechanisms of the rope embroidery device, until the next pattern is embroidered, the rope thread is embroidered on the fabric, and the movable knife, under the action of the first telescopic member, drives the movable knife and the rope-pressing part to stagger with each other to loosen the clamped rope thread, so as to carry out rope embroidery of a new pattern. In addition, the scissors assembly moves in the front-back direction. At the same time, in the vertical direction, the distance between the scissors assembly and the table plate is adjustable. In this way, the length of the remaining rope ends on the rope-embroidered pattern can be controlled, which avoids the remaining rope ends being too long to affect the embroidery quality, and further avoids the need to manually trim the remaining rope ends, which helps to improve the embroidery effect and reduce production costs.

[0039] The following further describes the present application in detail with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related utility model, rather than limiting the utility model. Additionally, it should be noted that for the sake of description, only the parts related to the utility model are shown in the drawings.

[0040] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will describe the present application in detail with reference to the drawings and embodiments.

[0041] At least refer to Figures 1 - 11 As shown, the present utility model example provides a rope embroidery device, including a rope cutting mechanism 100, and the rope cutting mechanism 100 is located on the left or right side of the machine head of the computer embroidery machine.

[0042] The rope cutting mechanism 100 includes: a scissor assembly 11, a first connection assembly 12 and a second connection assembly 13.

[0043] The first connecting component 12 is located between the scissor component 11 and the second connecting component 13 and connects the two. The second connecting component 13 can be connected to the left or right side of the housing of the head 200 of the computerized embroidery machine, and the second connecting component 13 can be connected to the left or right side of the needle bar holder 21 of the head 200 of the computerized embroidery machine.

[0044] As Figure 1 shown, the second connecting component 13 is connected to the right side of the needle bar holder 21 of the head 200, realizing that the rope cutting mechanism 100 is externally mounted on the right side of the head 200 of the computerized embroidery machine.

[0045] It should be noted that in the related art, if the rope cutting mechanism 100 is connected to one side of the housing of the head, the loop forming wheel 22 moves together with the needle bar holder 22. When the head is a 9-needle head, if any one of the needles from No. 4 to No. 9 embroiders, the rope between the loop forming wheel 22 and the scissor component 11 is too long, the tension of the rope is too large, or the rope between the loop forming wheel 22 and the scissor component 11 interferes with the thread clamp at the lower end of the needle bar holder. When the rope cutting mechanism 100 is connected to the needle bar holder 21, the rope cutting mechanism 100 can move left and right along with the needle bar holder 21. If any one of the needles from No. 4 to No. 9 embroiders, the length of the rope between the loop forming wheel and the scissor component 11 will not be too long, avoiding the rope lying on the fabric, and the tension of the rope is appropriate, avoiding the rope between the loop forming wheel 22 and the scissor component 11 interfering with the thread clamp at the lower end of the needle bar holder.

[0046] The following embodiments will be described with the rope cutting mechanism 100 externally mounted on the right side of the head 200 of the computerized embroidery machine:

[0047] As Figures 2 - 8 shown, the scissor component 11 includes a first telescopic member 116, a rope clamping member 113, a moving knife 112 and a fixed knife 111. The moving knife 112 is movably connected to the fixed knife 111, and the moving knife 112 has a rope cutting position and a rope loosening position when approaching or departing from the fixed knife 111. The rope clamping member 113 is provided with a rope pressing portion 1131 above the moving knife 112. When the moving knife 112 is in the rope cutting position, the rope pressing portion 1131 cooperates with the moving knife 112 to press the rope between the two. The first telescopic member 116 reciprocates in the left-right direction to enable the moving knife 112 to switch between the rope cutting position and the rope loosening position.

[0048] In practical applications, as Figure 5 or Figure 7 shown, the scissor component 11 includes a fixed knife 111, a moving knife 112, a rope clamping member 113, a pressing plate 114, a moving knife seat 115, a first telescopic member 116 and a bending plate 117.

[0049] The fixed knife 111 is connected to the left side of the movable knife seat 115. The movable knife seat 115 is provided with a slide groove (not marked) extending left and right, and the movable knife 112 is set in the slide groove. The movable knife 112 slides and cooperates with the slide groove, and the movable knife 112 reciprocates left and right along the slide groove. In this way, the movable knife 112 can approach the fixed knife 111 until the movable knife 112 cooperates with the fixed knife 111 to cut the rope. At this moment, the position of the movable knife 112 is the rope cutting position, such as Figure 6 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 slide slot and is stationary. At this moment, the position of the movable knife 112 is a rope-slack position, as shown in FIG. Figure 8 The first telescopic member 116 is connected to the movable knife 112 through the bending plate 117, and the first telescopic member 116 enables the movable knife 112 to reciprocate left and right. The first telescopic member 116 can be an electric push rod, a pneumatic push rod, a hydraulic push rod, etc.

[0050] The rope clamping member 113 is connected to the upper side of the moving knife seat 115. The rope clamping member 113 is provided with a rope pressing portion 1131, and the rope pressing portion 1131 is located above the fixed knife 111. In the vertical direction, there is a gap between the moving knife 112 and the rope pressing 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.

[0051] When the moving knife 112 is in the slack rope position, Figure 8 As shown, the rope is located in the gap between the moving knife 112 and the fixed knife 111. When the moving knife 112 switches from the rope loosening position to the rope cutting position, as shown in FIG. Figure 6 As shown, when the rope is cut, the rope is clamped between the moving knife 112 and the rope pressing part 1131. In this way, after embroidering a pattern, the rope is prevented from being separated from the loop wheel 22 of the rope embroidery device, or from other mechanisms of the rope embroidery device, until the next pattern is embroidered, the rope is embroidered on the fabric, and the moving knife 112 is driven by the first telescopic member 116 to stagger with the rope pressing part 1131 to loosen the clamped rope, so as to carry out rope embroidery of a new pattern.

[0052] 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 slot. The pressure plate 114 is arranged across the slide slot, that is, the pressure plate 114 limits and constrains the freedom of the movable knife 112 in the upward direction, so that the movable knife 112 moves left and right.

[0053] As an implementable manner, the movable knife 112 has a movable knife blade 1122 , the movable knife blade 1122 extends in a direction perpendicular to the direction from the movable knife 112 to the fixed knife 111 , and the rope pressing portion 1131 is arranged parallel to the movable knife blade 1122 .

[0054] like Figure 6 or Figure 8As shown, the moving blade 112 has a blade inclined surface 1121, and a moving blade edge 1122 and a moving blade back 1123 are provided on the blade inclined surface 1121 and are oppositely arranged. The moving blade edge 1122 extends in the left-right direction, and the rope pressing portion 1131 extends in the left-right direction. The length of the rope pressing portion 1131 may be equal to the length of the moving blade edge 1122, or the length of the rope pressing portion 1131 is slightly less than the length of the moving blade edge 1122. This helps to increase the probability that the cut rope is clamped between the moving blade 112 and the rope pressing portion 1131.

[0055] Further, when the moving blade 112 is in the rope cutting position, the surface of the rope pressing portion 1131 arranged on the same side as the blade inclined surface 1121 projects onto the blade inclined surface 1121, and the projection of the surface of the rope pressing portion 1131 arranged on the same side as the blade inclined surface 1121 is located on the blade inclined surface 1121.

[0056] As Figure 6 or Figure 8 shown, the length of the rope pressing portion 1131 is slightly less than the length of the moving blade edge 1122. When the moving blade 112 is in the rope cutting position, the surface of the rope pressing portion 1131 facing the left projects onto the blade inclined surface 1121, and the projection of the surface of the rope pressing portion 1131 facing the left is completely located on the blade inclined surface 1121. For example, the projection of the surface of the rope pressing portion 1131 facing the left may coincide with the moving blade edge 1122, or the projection of the surface of the rope pressing portion 1131 facing the left may coincide with the moving blade back 1123.

[0057] Preferably, as Figure 6 shown, the projection of the surface of the rope pressing portion 1131 facing the left is located between the moving blade back 1123 and the moving blade edge 1122, and the distance between the surface of the rope pressing portion 1131 facing the left and the moving blade edge 1122 in the left-right direction is d, where 0 mm ≤ d ≤ 2 mm. With this setting, on the one hand, it can increase the probability that the cut rope is clamped between the moving blade 112 and the rope pressing portion 1131, and on the other hand, it avoids affecting the flexibility of the moving blade 112 to switch from the rope cutting position to the rope loosening position due to the rope being clamped between the moving blade 112 and the rope pressing portion 1131.

[0058] As an implementable manner, in the vertical direction, there is a gap between the rope pressing portion 1131 and the moving blade 112, and the gap is adjustable.

[0059] In practical applications, considering the pattern effect of rope embroidery, rope of different diameters will be selected. In order to ensure that the force for clamping the rope between the rope pressing portion 1131 and the moving blade 112 is appropriate, to avoid the clamping force of the rope being too large or too small.

[0060] Based on this, the rope clamping member 113 is detachably connected to the upper side of the moving knife seat 115. The rope clamping member 113 can be connected to the upper side of the moving knife seat 115 through a fastener. By replacing different types of rope clamping members 113, the gap size between the rope pressing portion 1131 and the moving knife 112 in the vertical direction can be adjusted; alternatively, the rope clamping member 113 is sleeved on the fastener, and the fastener is rotated forward or backward to adjust the gap size between the rope pressing portion 1131 and the moving knife 112 in the vertical direction.

[0061] Of course, it can be understood that there can be other ways to adjust the gap size between the rope pressing portion 1131 and the moving knife 112 in the vertical direction, and they are not listed one by one in this embodiment.

[0062] As an implementable way, the moving knife blade 1122 of the scissors assembly 11 extends in the left - right direction and also extends in the horizontal direction. The distance between the moving knife blade 1122 and the table board in the vertical direction is between 1 mm and 2 mm. Such a setting helps to make the length of the remaining rope head on the embroidered pattern after rope embroidery shorter, avoiding the influence of too long remaining rope heads on the quality of the embroidered product, thus avoiding the need for manual trimming of the remaining rope heads, helping to improve the effect of the embroidered product and reducing production costs.

[0063] As an implementable way, the first connection assembly 12 enables the scissors assembly 11 to move left and right. Among them, the first connection assembly 12 is located on the right side of the head 200 of the computer embroidery machine.

[0064] As Figures 2 - 4 shown, the first connection assembly 12 includes a first support frame 121, a first slide rail 123, a first slider 122, a second support frame 124, and a second telescopic member 125. The second telescopic member 125 is the same as the first telescopic member 116.

[0065] The first slide rail 123 and the first slider 122 are clamped between the first support frame 121 and the second support frame 124. The first slider 122 is in sliding cooperation 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. The second telescopic member 125 is connected to the second support frame 124, and the power output end of the second telescopic member 125 enables the first support frame 121 to reciprocate in the left - right direction. Among them, the first support frame 121 is connected to the moving knife seat 115 of the above - mentioned scissors assembly 11.

[0066] The setting of the second telescopic member 125 can enable the scissors assembly 11 to reciprocate left and right. When moving leftward and approaching the sewing needle to cut the thread, as Figure 10 and Figure 11 shown; when moving rightward and away from the sewing needle to avoid the scissors assembly 11 interfering with other structures of the rope embroidery device, as Figure 9As shown in the figure. The setting of the first slider 122 and the first slide rail 123 limits or guides the movement of the first support frame 121, enabling the first support frame 121 to move left and right.

[0067] As an implementable mode, the third telescopic member 132 enables the scissor assembly 11 to reciprocate in the vertical direction, or enables the scissor assembly 11 to reciprocate in a direction inclined relative to the vertical direction. Among them, the third telescopic member 132 is located on the left or right side of the machine head.

[0068] As Figures 2 - 4 As shown in the figure, the second connection assembly 13 includes a third support frame 131, a second slide rail 133, a second slider 134, and a third telescopic member 132. The third telescopic member 132 is the same as the first telescopic member 116.

[0069] 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. Among them, the extending 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 above-mentioned second support frame 124 to achieve height adjustment of the first connection assembly 12 in the vertical direction, as Figures 9 - 11 shown in the figure. This enables the length of the remaining rope end on the embroidered pattern to be controllable, avoiding the problem that the remaining rope end is too long and affecting the quality of the embroidered product. Furthermore, it avoids the need for manual trimming of the remaining rope end, helps to improve the effect of the embroidered product, and reduces production costs.

[0070] Among them, the third support frame 131 is connected to the needle bar holder 21.

[0071] The setting of the third telescopic member 132 can adjust the height of the scissor assembly 11 in the vertical direction, that is, it can adjust the distance between the scissor assembly 11 and the table board of the computer embroidery machine.

[0072] The example of the present utility model further provides a rope embroidery device, including the above-mentioned rope cutting mechanism 100. The rope embroidery device has the advantages of the rope cutting mechanism 100, so it will not be elaborated here.

[0073] As Figure 1 shown in the figure, the example of the present utility model further provides a computer embroidery machine, including a machine head 200, a table board, and the above-mentioned rope embroidery device.

[0074] The rope cutting mechanism 100 of the rope embroidery device is located on one side of the machine head 200, and the scissor assembly 11 of the rope cutting mechanism 100 moves left and right. At the same time, in the vertical direction, the distance between the scissor assembly 11 and the table board is adjustable. This enables the length of the remaining rope end on the embroidered pattern to be controllable, avoiding the problem that the remaining rope end is too long and affecting the quality of the embroidered product. Furthermore, it avoids the need for manual trimming of the remaining rope end, helps to improve the effect of the embroidered product, and reduces production costs.
