Tapping embroidery device

Abstract

According to the taping embroidery device, when a fixing sleeve rotates, a thread wheel frame and a tightness adjusting piece rotate along with the fixing sleeve, and a connecting part of the tightness adjusting piece slides in the circumferential direction of an annular rail; due to the fact that the connecting part is arranged on the annular rail of the sliding sleeve, when the sliding sleeve moves in the axis direction of the fixing sleeve, the feeding hole of the tightness adjusting piece swings up and down within the range of the angle alpha relative to the hinged position, the tightness degree of a rope or a silk ribbon is appropriate, pulling deformation of a pattern to be embroidered is avoided, and the attractiveness and the artistic effect of the pattern are guaranteed. Meanwhile, the situation that the sewing of the machine needle is inaccurate due to the fact that the rope or the silk ribbon located at the embroidery position of the machine needle is suspended is avoided, and it can be guaranteed that the rope or the silk ribbon can be stably locked to the cloth after sewing is conducted.

Description

Technical Field

[0001] This utility model generally relates to the field of computerized embroidery machine technology, and more particularly to a ribbon embroidery device. Background Technology

[0002] The ribbon embroidery device is used for embroidering ribbons, cords, etc. During ribbon embroidery, the thread wheels on the thread spool frame output the cord or ribbon, the needle inserts into the cord or ribbon, and the top thread secures the cord or ribbon to the fabric. The fabric is placed on the embroidery frame, and as the frame moves, the cord or ribbon is pulled out from the thread wheels.

[0003] If the thread roller outputs rope or ribbon in a timely manner or cannot keep up with the rhythm of the needle embroidery, a large pulling force will exist between the fabric and the thread roller, which will pull and deform the pattern to be embroidered, seriously affecting the beauty and artistic effect of the pattern. Utility Model Content

[0004] This application aims to provide a ribbon embroidery device machine, at least for use in...

[0005] This utility model provides a shearing device, including a fixed sleeve, a wire wheel frame, a tension adjusting component, a sliding sleeve, and a drive rod.

[0006] The reel frame is used to mount the reel, the tension adjustment member is provided with a connecting part and a feeding hole for the rope or ribbon on the reel to pass through, and the sliding sleeve is provided with an annular track;

[0007] The reel frame is fixedly connected to the fixed sleeve, the fixed sleeve passes through the sliding sleeve, the tension adjustment member is hinged to the fixed sleeve or the reel frame, and the connecting part of the tension adjustment member cooperates with the annular track, and the drive rod is connected to the sliding sleeve.

[0008] When the fixed sleeve rotates, the connecting part slides with the annular track to allow the connecting part to slide circumferentially along the annular track; when the drive rod causes the sliding sleeve to move along the axis of the fixed sleeve, the connecting part connects with the annular track to allow the feeding hole to rotate relative to the hinge position to a preset position, thereby adjusting the tension of the rope or the ribbon.

[0009] As an alternative implementation, the fixed sleeve and the sliding sleeve are coaxially arranged, and there is a gap between them.

[0010] As an implementation method, the side of the sliding sleeve is recessed in the circumferential direction to form an annular groove, the annular groove being the annular track, and the connecting portion being at least partially disposed within the annular groove.

[0011] As an alternative implementation, the connecting portion is adapted to the annular groove, and the connecting portion is completely disposed within the annular groove.

[0012] As an alternative implementation, the connecting portion makes rolling contact with the annular groove.

[0013] As an alternative method, a ceramic feed sleeve is installed in the feed hole.

[0014] As an alternative implementation, the tension adjustment member is hinged to the fixed sleeve via a connector.

[0015] As one possible implementation, the tension adjustment component includes a body, which includes a first part and a second part connected to each other. A hinge hole is provided at the connection position between the first part and the second part. A hinge shaft with a bearing is sleeved through the hinge hole and installed on the connector. The connector is fixedly connected to the fixed sleeve. The second part is provided with the feeding hole, and the first part is provided with the connecting part.

[0016] As one possible implementation, the connector has a through hole and a locking hole that are interconnected. The hinge shaft is disposed in the through hole, the axis of the locking hole is perpendicular to the axis of the through hole, and the locking member passes through the locking hole and locks into the hinge shaft.

[0017] In the above-described scheme, when the fixed sleeve rotates, the thread wheel frame and tension adjustment component rotate with the fixed sleeve, and the connecting part of the tension adjustment component slides circumferentially along the annular track. Since the connecting part is set on the annular track of the sliding sleeve, when the sliding sleeve moves along the axis of the fixed sleeve, the feeding hole of the tension adjustment component swings up and down within the angle α range relative to the hinge position, thereby making the tension of the rope or ribbon appropriate, avoiding the deformation of the embroidered pattern, and helping to ensure the beauty and artistic effect of the pattern. At the same time, it avoids the rope or ribbon at the needle embroidery point from being suspended in the air, which would cause the needle to be inaccurate, and helps to ensure that the rope or ribbon can be stably locked to the fabric after the needle is inserted.

Detailed Implementation

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] The ribbon embroidery device is used for embroidering ribbons, cords, etc. During the ribbon embroidery process, the thread wheel 22 on the thread wheel frame 20 outputs the cord or ribbon, the needle inserts into the cord or ribbon, and the top thread locks the cord or ribbon onto the fabric. The fabric is placed on the embroidery frame, and as the embroidery frame moves, the cord or ribbon is pulled out from the thread wheel 22.

[0029] If the output of rope or ribbon from the thread roller 22 is not timely or cannot keep up with the rhythm of the needle embroidery, a large pulling force will exist between the fabric and the thread roller 22, which will pull and deform the pattern to be embroidered, seriously affecting the beauty and artistic effect of the pattern.

[0030] Based on this, this application proposes a ribbon embroidery device that can adjust the tension of the rope or ribbon. When the rope or ribbon is too tense, it can suppress the tension, allowing the rope or ribbon to loosen, thereby preventing the embroidered pattern from being pulled and deformed, which helps to ensure the aesthetics and artistic effect of the pattern; at the same time, it prevents the needle from being inaccurate due to the rope or ribbon being suspended at the needle embroidery point, which helps to ensure that the rope or ribbon can be stably locked to the fabric after the needle is inserted.

[0031] In detail, at least see Figures 1-6 As shown, the embroidery device includes: a fixed sleeve 10, a thread wheel frame 20, a tension adjusting component 30, a sliding sleeve 50, a drive rod 60, and a needle bar 70.

[0032] The reel holder 20 is used to mount the reel 22. The tension adjusting member 30 is provided with a connecting part and a feeding hole 3121 through which the rope or ribbon on the reel 22 passes. The sliding sleeve 50 is provided with an annular track. The reel holder 20 is fixedly connected to the fixed sleeve 10, which passes through the sliding sleeve 50. The tension adjusting member 30 is hinged to the fixed sleeve 10 or the reel holder 20, and the connecting part of the tension adjusting member 30 cooperates with the annular track. The drive rod 60 is connected to the sliding sleeve 50.

[0033] When the fixed sleeve 10 rotates, the connecting part slides in conjunction with the annular track so that the connecting part slides along the circumference of the annular track; when the drive rod 60 causes the sliding sleeve 50 to move along the axis of the fixed sleeve 10, the connecting part connects in conjunction with the annular track so that the feeding hole 3121 rotates to a preset position relative to the hinge position to adjust the tightness of the rope or ribbon.

[0034] Among them, such as Figure 1 and Figure 2 As shown, the needle bar 70 is arranged vertically, and the fixing sleeve 10 is ring-shaped. The needle bar 70 passes through the fixing sleeve 10, and the two are coaxially arranged. The fixing sleeve 10 is movably connected to the needle bar 70, that is, when the fixing sleeve 10 is driven to rotate by a related mechanism, the fixing sleeve 10 can rotate relative to the needle bar 70. Figure 3 and Figure 4 As shown, the reel frame 20 includes a frame 21 and reels 22. Two reels 22 are mounted on the frame 21 and spaced apart from each other. The lower end of the fixing sleeve 10 is located between the two reels 22 and is fixedly connected to the frame 21. In this way, the fixing sleeve 10 can drive the reel frame 20 to rotate 360°.

[0035] like Figure 3 and Figure 4 As shown, each tension adjusting member 30 corresponds to one of the reels 22. Each reel 22 is provided with a tension adjusting member 30, which is hinged to the lower end of the fixed sleeve 10. The tension adjusting member 30 has a connecting part and a feeding hole 3121 spaced apart, and a hinge position of the tension adjusting member 30 is provided between the connecting part and the feeding hole 3121. The feeding hole 3121 is positioned corresponding to the middle position of the reel 22.

[0036] like Figure 6As shown, the sliding sleeve 50 includes an annular body 51 and a clamping structure 52. The side of the annular body 51 is recessed in the circumferential direction to form an annular track, namely an annular groove 511. The dimensions of the annular groove 511 from its opening to its bottom are all equal, making the annular groove 511 a uniformly sized groove. Of course, it can be understood that the opening size of the annular groove 511 can be larger than the bottom size, or the opening size of the annular groove 511 can be smaller than the bottom size.

[0037] The clamp structure 52 includes a clamp hole 521. The drive rod 60 is inserted into the clamp hole 521, and the two are fixedly connected. The drive rod 60 reciprocates in the vertical direction, thereby driving the sliding sleeve 50 to reciprocate in the vertical direction.

[0038] The fixed sleeve 10 passes through the sliding sleeve 50, and the fixed sleeve 10 and the sliding sleeve 50 are coaxially arranged with a gap between them. In this way, the side of the fixed sleeve 10 will not affect the vertical movement of the sliding sleeve 50, which helps the sliding sleeve 50 to move freely. The connecting part of the tension adjusting member 30 is at least partially provided in the annular groove 511. The connecting part can be a slider, pulley 33, ball bearing, etc.

[0039] At least combine Figure 1 and Figure 5 As shown, when the drive rod 60 causes the sliding sleeve 50 to move in the vertical direction (or, the direction of the axis of the fixed sleeve 10), since the connecting part is located in the annular groove 511 of the sliding sleeve 50, the feeding hole 3121 swings up and down relative to the hinge position within the angle α range. When the sliding sleeve 50 moves upward, the feeding hole 3121 moves downward; when the sliding sleeve 50 moves downward, the feeding hole 3121 moves upward. In this way, the feeding hole 3121 rotates to the preset position relative to the hinge position, thereby making the tension of the rope or ribbon appropriate (e.g., Figure 1 The red line represents a rope, which helps to prevent the embroidered pattern from being pulled and deformed, thus ensuring the beauty and artistic effect of the pattern. At the same time, it helps to prevent the rope or ribbon located at the embroidery needle from being suspended in the air, which would cause the needle to be inaccurate. It also helps to ensure that the rope or ribbon can be stably locked to the fabric after the needle is inserted.

[0040] When the fixed sleeve 10 rotates, the reel frame 20 and the tension adjustment member 30 rotate with the fixed sleeve 10. The connecting part slides circumferentially along the annular groove 511, so that the connecting part of the tension adjustment member 30 can always be located in the annular groove 511 of the sliding sleeve 50, which helps the sliding sleeve 50 to move in the vertical direction and drive the tension adjustment member 30 to adjust the tension of the rope or ribbon.

[0041] In summary, in this embodiment, when the fixed sleeve 10 rotates, the thread wheel frame 20 and the tension adjustment component 30 rotate with the fixed sleeve 10, and the connecting part of the tension adjustment component 30 slides circumferentially along the annular track. Since the connecting part is set on the annular track of the sliding sleeve 50, when the sliding sleeve 50 moves along the axis of the fixed sleeve 10, the feed hole 3121 of the tension adjustment component 30 swings up and down relative to the hinge position within the angle α range, thereby making the tension of the rope or ribbon appropriate, avoiding the deformation of the embroidered pattern, and helping to ensure the beauty and artistic effect of the pattern. At the same time, it avoids the rope or ribbon at the needle embroidery point from being suspended, which would cause the needle to be inaccurate, and helps to ensure that the rope or ribbon can be stably locked to the fabric after the needle is inserted.

[0042] As one possible implementation, the connecting part is adapted to the annular groove 511, allowing the connecting part to be inserted into the annular groove 511. That is, at least in combination... Figure 5 and Figure 6 As shown, the height of the connecting part is matched with the width of the annular groove 511, and the connecting part is completely set inside the annular groove 511 with a clearance fit between them. On the one hand, this can prevent the connecting part from detaching from the annular groove 511, so that the connecting part is always located inside the annular groove 511. On the other hand, it can increase the contact area between the connecting part and the annular groove 511, so that when the sliding sleeve 50 moves in the vertical direction, the tension adjustment component 30 can stably adjust the tension of the rope or ribbon.

[0043] As an option, the connecting part makes rolling contact with the annular groove 511.

[0044] At least combine Figure 5 and Figure 6 As shown, the connecting part is a pulley 33. The pulley 33 is disposed within the annular groove 511, and its diameter is slightly smaller than the width of the annular groove 511. The pulley 33 and the annular groove 511 are in clearance fit. The pulley 33 rolls in contact with the annular groove 511, allowing the tension adjusting member 30 to roll upwards around the annular groove 511. This reduces the friction between the connecting part and the annular groove 511, allowing the connecting part to rotate freely within the annular groove 511. During the rotation of the fixed sleeve 10, the tension adjusting member 30 remains relatively stationary, ensuring that the tension of the rope or ribbon remains constant.

[0045] As an alternative, the tension adjustment member 30 is hinged to the fixed sleeve 10 via the connector 40.

[0046] like Figures 3-5As shown, the tension adjustment component 30 includes a body 31, which comprises a first part 311 and a second part 312 connected to each other. The first part 311 and the second part 312 are set at a preset acute angle. A hinge hole 34 is provided at the connection position between the first part 311 and the second part 312, and a hinge shaft 35 is mounted in the hinge hole 34 via a bearing. The second part 312 is provided with a feeding hole 3121, and the first part 311 is provided with a pulley 33.

[0047] The connector 40 has a through hole 41, a locking hole 42, and a fixing hole 43. The axes of the locking hole 42 and the fixing hole 43 are parallel, and the axis of the through hole 41 is perpendicular to the axes of the locking hole 42 and the fixing hole 43. A fastener passes through the fixing hole 43 and is threaded to the lower end of the fixing sleeve 10, thus fixing the connector 40 to the fixing sleeve 10. The aforementioned hinge shaft 35 is disposed within the through hole 41, enabling the tension adjustment component 30 to be hinged. Considering that the hinge shaft 35 may loosen and detach from the through hole 41 during prolonged operation, a locking member passes through the locking hole 42 and locks into the hinge shaft 35. This prevents the hinge shaft 35 from loosening and detaching from the through hole 41, ensuring a stable hinged connection for the tension adjustment component 30.

[0048] As an alternative, the ceramic feed sleeve 32 is installed in the feed hole 3121.

[0049] like Figure 5 As shown, in practical applications, considering that the rope or ribbon is under tension when passing through the feed hole 3121, the contact point between the feed hole 3121 and the rope or ribbon is prone to scratching the rope or ribbon. Therefore, a ceramic feed sleeve 32 is installed in the feed hole 3121, so that the rope or ribbon can pass freely through the ceramic feed sleeve 32, avoiding damage to the rope or ribbon due to tension.
