Abstract
Description
Technical Field
[0001] The utility model generally relates to the technical field of computer embroidery machines, and particularly relates to a rope clamping mechanism, 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. At present, the vast majority of embroidery ropes on the 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 ends 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 device to thread and cut ropes in an automated manner. Summary of the Utility Model
[0004] This application expects to provide a rope clamping mechanism, a rope embroidery device and a computer embroidery machine, at least for automatically cutting threads to improve the efficiency of rope embroidery.

[0007] A rope clamping part is provided on the rope clamping seat, the rope hooking member is arranged on the rope clamping seat, the rope hooking member is slidably matched with the rope clamping seat, and the rope hooking part is close to the rope clamping part to clamp the rope between the two.
[0008] Wherein, the rope hooking part elastically presses against the rope, or the rope clamping part elastically presses against the rope.
[0009] As an implementable mode, the surface of the rope hooking part in contact with the rope is a curved surface, and the surface of the rope clamping part in contact with the rope is a plane; or
[0010] The surface of the rope hooking part in contact with the rope is a plane, and the surface of the rope clamping part in contact with the rope is a curved surface.
[0011] As an implementable mode, the surface of the rope clamping part in contact with the rope is an inclined plane.
[0012] As an implementable mode, it further includes a first telescopic member, which is a single-acting cylinder or a hydraulic cylinder, and the power output end of the first telescopic member is connected to the hook rope member.
[0013] As an implementable mode, it further includes a second telescopic member, which is the same as the first telescopic member.
[0014] The second telescopic member is arranged in parallel with the first telescopic member, and the power output end of the second telescopic member drives the power output end of the first telescopic member to move in the same direction.
[0015] As an implementable mode, it further includes a third telescopic member, which makes the rope clamping seat reciprocate in the vertical direction, or makes the rope clamping seat reciprocate in a direction inclined relative to the vertical direction.
[0016] The utility model provides a rope embroidery device, which includes a scissor mechanism and the above-mentioned rope clamping mechanism, and the scissor mechanism and the rope clamping mechanism are independent of each other. The scissor mechanism includes a scissor assembly, and the scissor assembly reciprocates in the front-rear direction; the hook rope member of the rope clamping mechanism reciprocates in the left-right direction.
[0017] The utility model provides a computerized embroidery machine, which includes a machine head, a table board and the above-mentioned rope embroidery device, and the rope clamping mechanism of the rope embroidery device is connected to one side of the needle bar holder of the machine head, or / and, connected to one side of the machine shell of the machine head.
[0018] As an implementable mode, the scissor assembly of the scissor mechanism of the rope embroidery device is located between the needle bar holder of the machine head and the table board, and in the vertical direction, the distance between the scissor assembly and the table board is adjustable.
[0019] The rope clamping seat and the hook rope member of the rope clamping mechanism of the rope embroidery device are located between the needle bar holder of the machine head and the table board, and in the vertical direction, the distance between the rope clamping seat and the table board is adjustable.
[0020] In the above scheme, the present application adopts the sliding cooperation between the rope hook member and the rope clamping seat, and the rope hook portion is close to the rope clamping portion to clamp the rope between the two, and the rope hook portion elastically presses the rope, or the rope clamping portion elastically presses the rope. When the rope embroidery device is working, after the rope is cut by the scissors mechanism, the rope is clamped between the rope hook portion of the rope hook member and the rope clamping portion of the rope clamping seat. In this way, when a pattern is embroidered, it is prevented that the rope is separated from the loop wheel of the rope embroidery device, or from other mechanisms of the rope embroidery device. Because the rope hook part and the rope clamp part clamp the rope between them under the action of the spring of the first telescopic member, the rope hook part elastically presses against the rope, which helps to clamp various types of ropes between the rope hook part and the rope clamp part, such as cotton rope, nylon rope, polyester rope, hemp rope, etc., avoids excessive clamping force, which leads to the rope hook part and the rope clamp part being unable to stagger freely, avoids excessive clamping force, which affects the glossiness of the rope, and avoids excessive clamping force, which leads to the rope detaching from the loop wheel of the rope embroidery device. In addition, it helps to clamp ropes of the same type but different diameters between the rope hook part and the rope clamp part, and avoids excessive or insufficient clamping force.

[0034] 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 relevant utility model and do not limit the utility model. In addition, it should be noted that for the convenience of description, only the parts related to the utility model are shown in the drawings.
[0035] 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.
[0036] At least refer to Figure 1 - Figure 9 As shown, an example of the present utility model provides a rope embroidery device including a scissor mechanism 200 and a rope clamping mechanism 100, and the scissor mechanism 200 and the rope clamping mechanism 100 are independent of each other.
[0037] The scissor mechanism 200 can be connected to the left or right side of the housing of the head of the computer embroidery machine, and the rope clamping mechanism 100 can be connected to the left or right side of the housing of the head, or the rope clamping mechanism 100 can also be connected to the left or right side of the needle bar holder 300 of the head.
[0038] Such as Figures 1 - 3 As shown, the scissor mechanism 200 is connected to the right side of the head, and the rope clamping mechanism 100 is connected to the right side of the needle bar holder 300.
[0039] It should be noted that in the related art, the rope clamping mechanism 100 is installed on one side of the machine head, and the loop forming wheel moves together with the needle bar holder 300. When the machine head is a 9-needle machine head, if any one of the needles No. 4 to No. 9 embroiders, the rope between the loop forming wheel and the rope clamping mechanism 100 is too long, the tension of the rope is too large, or the rope between the loop forming wheel and the rope clamping mechanism 100 interferes with the thread clamp at the lower end of the needle bar holder. The rope clamping mechanism 100 is connected to the needle bar holder 300, and the rope clamping mechanism 100 can move left and right along with the needle bar holder 300. If any one of the needles No. 4 to No. 9 embroiders, the length of the rope between the loop forming wheel and the rope clamping mechanism 100 will not be too long, preventing the rope from lying on the fabric, and the tension of the rope is appropriate, avoiding the interference between the rope between the loop forming wheel and the rope clamping mechanism 100 and the thread clamp at the lower end of the needle bar holder 300.
[0040] Among them, as Figure 8 and Figure 9 shown, the scissor mechanism 200 includes a scissor assembly 21, a first connection assembly 22, a second connection assembly 23 and a connecting plate 24. The first connection assembly 22 includes a front-back telescopic member 221, and the front-back telescopic member 221 enables the scissor assembly 21 to reciprocate in the front-back direction; the second connection assembly 23 includes an up-down telescopic member 231, and the up-down telescopic member 231 enables the scissor assembly 21 to reciprocate in the vertical direction. Among them, the up-down telescopic member 231 is the same as the front-back telescopic member 221, and can be an electric push rod, a hydraulic push rod, a pneumatic push rod, etc.
[0041] As Figure 9 shown, the scissor assembly 21 is connected to the first connection assembly 22 through the connecting plate 24. The power output end of the front-back telescopic member 221 of the first connection assembly 22 is connected to the scissor assembly 21, enabling the scissor assembly 21 to move back and forth. The power output end of the up-down telescopic member 231 of the second connection assembly 23 is connected to the first connection assembly 22, enabling the first connection assembly 22 to move up and down, and thus realizing the up and down movement of the scissor assembly 21.
[0042] The first connection assembly 22 further includes a guiding assembly (not labeled). The guiding assembly includes a sliding rail and a slider in sliding fit, and guides the power output end of the front-back telescopic member 221 to move in the front-back direction through the guiding assembly. Similarly, the second connection assembly 23 also further includes a guiding assembly (not labeled), and the guiding assembly guides the power output end of the up-down telescopic member 231 to move in the up-down direction.
[0043] It should be noted that, since the back side of the casing (the surface facing the rear) is an inclined surface, there is a slightly larger space behind the casing. When the scissor assembly 21 moves in the front-to-back direction, the initial position of the scissor assembly 21 is located behind the casing, which cleverly utilizes the above space and avoids the scissor assembly 21 occupying the space on the left or right side of the machine head. In addition, when the movable knife of the scissor assembly 21 moves in the front-to-back direction, the movable knife is located between the needle bar frame 300 and the table of the computer embroidery machine, and the height between the scissor assembly 21 and the table can be adjusted by the upper and lower telescopic parts 231, so that the length of the rope head remaining on the rope embroidery pattern can be controlled, avoiding the residual rope head being too long to affect the quality of the embroidery, and thus avoiding the need to manually trim the residual rope head, which helps to improve the embroidery effect and reduce production costs.
[0044] Among them, Figures 3 - 7 As shown, the rope clamping mechanism 100 includes: a rope hook member 12 , a rope clamping seat 11 , a first telescopic member 13 , a second telescopic member 15 and a connecting member 14 .
[0045] The rope clamping seat 11 is provided with a slide groove (not marked), which extends in the left-right direction, and the rope hooking member 12 is arranged in the slide groove. The first telescopic member 13 is the same as the second telescopic member 15, and the first telescopic member 13 and the second telescopic member 15 are arranged in parallel and are arranged in the left-right direction.
[0046] like Figure 6 and Figure 7 As shown, the power output end of the first telescopic member 13 is connected to the rope hook member 12, so that the rope hook member 12 reciprocates in the left and right directions. Since the first telescopic member 13 is a single-acting cylinder or hydraulic cylinder, the first telescopic member 13 makes the rope hook member 12 move from right to left under the action of air pressure or hydraulic pressure, and there is a gap between the rope hook portion 121 of the rope hook member 12 and the rope clamping portion 111 on the rope clamping seat 11. The rope can be located in the gap. Under the action of the spring of the first telescopic member 13, the rope hook member 12 moves from left to right, and the rope hook portion 121 of the rope hook member 12 approaches the rope clamping portion 111 on the rope clamping seat 11, until the rope hook portion 121 and the rope clamping portion 111 clamp the rope between them.
[0047] The power output end of the second telescopic member 15 is connected to the power output end of the first telescopic member 13 through the connecting member 14. The power output end of the second telescopic member 15 moves from right to left, which can drive the power output end of the first telescopic member 13 to move from right to left, and then the rope hook part 121 and the rope clamping part 111 are offset to loosen the clamped rope.
[0048] When the rope embroidery device is working, after the rope is cut by the scissor mechanism 200, the rope is clamped between the rope hook part 121 of the rope hook member 12 and the rope clamping part 111 of the rope clamping seat 11. In this way, after embroidering a pattern, the rope is prevented from being separated from the loop wheel of the rope embroidery device, or from other mechanisms of the rope embroidery device. Because the rope hook part 121 and the rope clamping part 111 clamp the rope between them under the spring action of the first telescopic member 13, the rope hook part 121 elastically presses against the rope, which helps to clamp various types of ropes between the rope hook part 121 and the rope clamping part 111, such as cotton rope, nylon rope, polyester rope, hemp rope, etc., and avoids excessive clamping force, which leads to the rope hook part 121 and the rope clamping part 111 being unable to stagger freely, and avoids excessive clamping force affecting the glossiness of the rope; avoids too small clamping force, which leads to the rope being separated from the loop wheel of the rope embroidery device. In addition, it helps to clamp the same type of ropes with different diameters between the rope hook portion 121 and the rope clamp portion 111, thereby avoiding excessive or insufficient clamping force.
[0049] Of course, it is understood that in some embodiments, the rope hook portion 121 is rigidly pressed against the rope, while the rope clamping portion 111 is elastically pressed against the rope. Alternatively, the rope hook portion 121 is elastically pressed against the rope, and the rope clamping portion 111 is elastically pressed against the rope.
[0050] After embroidering one pattern, when the rope is about to embroider the next pattern, the rope is embroidered on the fabric, and the power output end of the first telescopic member 13, under the action of the power output end of the second telescopic member 15, drives the rope hook part 121 and the rope clamp part 111 to stagger with each other to loosen the clamped rope, thereby performing rope embroidery of a new pattern.
[0051] As an implementable manner, the surface of the rope hooking portion 121 in contact with the rope is a curved surface, and the surface of the rope clamping portion 111 in contact with the rope is a flat surface; or,
[0052] The surface of the rope hooking portion 121 that contacts the rope is a flat surface, and the surface of the rope clamping portion 111 that contacts the rope is a curved surface.
[0053] like Figure 4 and Figure 5 As shown, the surface in contact with the rope on the rope clamping part 111 is an inclined plane. A cylindrical rod 1211 is welded on the rope hooking part 121, and the cylindrical rod 1211 is in contact with the rope. Since the area in contact with the cylindrical rod 1211 and the rope is smaller than the area in contact with the inclined plane and the rope, this helps to ensure that the clamping force between the cylindrical rod 1211 and the inclined plane is appropriate, avoiding excessive or too small clamping force. In addition, when the inclined plane and the cylindrical rod 1211 clamp the rope, the friction force on the rope is small, avoiding affecting the glossiness of the rope, and helping to ensure the rope embroidery effect of the rope embroidery pattern.
[0054] Of course, it can be understood that the surface of the hook rope part 121 in contact with the rope can be a curved surface, and the surface of the rope clamping part 111 in contact with the rope is a curved surface; or, the surface of the hook rope part 121 in contact with the rope can be a flat surface, and the surface of the rope clamping part 111 in contact with the rope is a flat surface. Here, the "flat surface" can be an inclined flat surface or a horizontal flat surface.
[0055] As an implementable mode, the rope clamping mechanism 100 further includes a first support frame 16, a third telescopic member 17, and a second support frame 18.
[0056] Such as Figures 3 - 7 shown, the third telescopic member 17 can be an electric push rod, a hydraulic push rod, a pneumatic push rod, and so on.
[0057] The rope clamping seat 11 is connected to the first support frame 16, and the power output end of the third telescopic member 17 is connected to the first support frame 16. Among them, the power output end of the third telescopic member 17 reciprocates in the vertical direction or a 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 matches the height of the scissors assembly 21 of the above-mentioned scissors mechanism 200 to ensure that the two cooperate to complete wire cutting.
[0058] A guiding assembly is provided between the third telescopic member 17 and the second support frame 18. The guiding assembly is used to guide the power output end of the third telescopic member 17 to reciprocate in the vertical direction or a direction inclined relative to the vertical direction. The second support frame 18 is connected to the right side of the needle bar frame 300.
[0059] The present utility model example also provides a computerized embroidery machine including a machine head, a table board, and the above-mentioned rope embroidery device.
[0060] The scissors assembly 21 of the scissors mechanism 200 of the rope embroidery device is located between the needle bar frame 300 of the machine head and the table board. In the vertical direction, the distance between the scissors assembly 21 and the table board is adjustable. This makes the length of the remaining rope head on the embroidered pattern controllable, avoids the influence of the too long remaining rope head on the quality of the embroidered product, and further avoids the need for manual trimming of the remaining rope head, which helps to improve the effect of the embroidered product and reduce the production cost.
[0061] The rope clamping seat 11 and the hook rope member 12 of the rope clamping mechanism 100 are located between the needle bar frame 300 of the machine head and the table board. In the vertical direction, the distance between the rope clamping seat 11 and the table board is adjustable. The height of the rope clamping seat 11 matches the height of the scissors assembly 21 of the scissors mechanism 200 to ensure that the two cooperate to complete wire cutting.
