Description

Technical Field

[0001] The utility model relates to the technical field of embroidery machines, in particular to a bead embroidery device with adjustable lower beads. Background Art

[0002] A bead embroidery machine is a bead embroidery device that can realize the functions of placing and feeding beads on the head of an ordinary embroidery machine. However, with the progress of society, traditional bead embroidery mechanisms can no longer meet people's demand for higher quality bead embroidery products, and two-color, three-color, or even multi-color bead embroidery devices have begun to appear on the market. For example, a Chinese invention patent with publication number CN114150448B discloses a three-color bead embroidery device on an embroidery machine, including a lifting component, a first feeding component and a second feeding component are fixedly installed above the lifting component, a first bead feeding component and a second bead feeding component are fixedly installed below the lifting component, the first feeding component is arranged in coordination with the first bead feeding component, and the second feeding component is arranged in coordination with the second bead feeding component. The three-color bead embroidery device can simultaneously perform bead embroidery operations on three different specifications of embroidery beads, and the bead embroidery effect is good, and it effectively reduces equipment costs and reduces the area of ​​use of the site.

[0003] However, the above three-color bead embroidery device still has the following defects:

[0004] 1. Generally speaking, in order to ensure that the embroidery beads can accurately fall on the predetermined position on the first bead feeding component, the distance from the end (lower end) of the first steel wire to the first bead feeding component is usually equal to or slightly greater than the height of an embroidery bead, so as to ensure that the embroidery beads will not roll when falling on the first bead feeding component and can also fall completely out of the first steel wire.

[0005] In the above-mentioned three-color bead embroidery device, the first steel wire has to guide the embroidery beads of different specifications to fall onto the first bead feeding assembly, but the distance from the end (lower end) of the first steel wire to the first bead feeding assembly is indeed fixed, which will cause small embroidery beads (whose height dimension is smaller than the distance from the end of the first steel wire to the first bead feeding assembly) to roll when falling onto the first bead feeding assembly, and will also cause large embroidery beads (whose height dimension is larger than the distance from the end of the first steel wire to the first bead feeding assembly) to be stuck at the end of the first steel wire, thereby causing the end of the first steel wire to bend and deform under the bead pushing action of the first bead feeding assembly, seriously affecting the quality and efficiency of the bead embroidery operation.

[0006] Second, except for being able to perform bead embroidery operations on embroidery beads of three different specifications, the three-color bead embroidery device does not have any additional functions, and its functions are relatively single, which is not suitable for industrialized bead embroidery production operations.

The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0028] See also Figures 1 to 5A bead embroidery device with adjustable lower beads in a specific embodiment of the utility model comprises a frame 1 and three sets of bead embroidery mechanisms arranged on the frame 1. The three sets of bead embroidery mechanisms are arranged in a row on the frame 1, and the three sets of bead embroidery mechanisms are all used to transport embroidery beads to the needle position of the embroidery machine. Wherein, the bead embroidery mechanism includes a bead bin assembly 2, a lower bead control assembly 3, a bead feeding assembly 4, and a bead output wire 5. The bead bin assembly 2, the lower bead control assembly 3, and the bead feeding assembly 4 are arranged in sequence from high to low, the upper end of the bead output wire 5 extends into the bead bin assembly 2, and the lower end of the bead output wire 5 is located directly above the bead feeding position of the bead feeding assembly 4, and the lower bead control assembly 3 is arranged at the middle position of the bead output wire 5; the embroidery beads can be strung onto the bead output wire 5 from the bead bin assembly 2, and move along the bead output wire 5 by relying on their own gravity to pass through the lower bead control assembly 3, and finally fall onto the bead feeding position of the bead feeding assembly 4, so that the embroidery beads on the bead feeding position can be pushed to the needle position of the embroidery machine by the bead feeding assembly 4.

[0029] In this embodiment, the lower bead control component 3 includes a clamping roller group 31 vertically arranged on the frame 1, and five clamping elements 32 mounted on the clamping roller group 31. The clamping roller group 31 includes two clamping rollers arranged parallel to each other. The two clamping arms of each clamping element 32 are respectively arranged on a clamping roller, and a reset torsion spring is provided between the two clamping arms. The reset torsion spring is also mounted on the clamping roller; the clamping end of each clamping element 32 is clamped on the bead output steel wire 5. It also includes a wheel axle 33 arranged parallel to the clamping roller group 31, five driving cams 34 arranged on the wheel axle 33 corresponding to each clamp element 32, and a lower bead driving motor connected to the wheel axle 33. Each clamp element 32 has a clamping arm extending into the rotating area of ​​the driving cam 34. The driving cam 34 rotates under the drive of the lower bead driving motor and moves the clamping arm during the rotation to open the clamp element 32. However, when the driving cam 34 rotates to move away from the clamp element 32, the clamp element 32 will automatically reset to the state of clamping the bead wire 5 under the elastic force of the reset torsion spring.

[0030] It should be noted that: in this embodiment, any two adjacent driving cams 34 are oriented in different directions; that is, when the bead lowering driving motor is working, at least one of the five clip elements 32 is always in a clamping state of clamping the bead output wire 5, so that the bead lowering control assembly 3 can stably clamp and fix the middle section of the bead output wire 5. Moreover, during the rotation of the axle 33, the five clip elements 32 will also be installed to open in a specific order, so that the embroidery beads on the bead output wire 5 that were originally blocked by the clip elements 32 can fall to the bead feeding position as required for the embroidery operation.

[0031] In addition, in order to facilitate those skilled in the art to understand the technical solution of the present application through the accompanying drawings, Figure 1 Only one bead-out steel wire 5 is shown, and the other two are in a hidden state and are not shown.

[0032] In addition, in this embodiment, the frame 1 is also provided with an adjusting bolt 35 for pushing the clamping roller downward, and a reset spring 36 sleeved on the clamping roller for pushing the clamping roller upward. Among them, a top block is fixedly installed on the upper end of the clamping roller group 31, the adjusting bolt 35 is threadedly installed on the frame 1, and the lower end of the adjusting bolt 35 extends through the frame 1 and abuts against the upper end surface of the top block; the clamp element 32 at the lower end of the clamping roller is movably arranged on the clamping roller, and the reset spring 36 is sleeved on the lower end of the clamping roller, and the lower end of the reset spring 36 is pressed against the clamp element 32 at the lower end of the clamping roller through a washer, and the upper end is pressed against the lower end surface of the fourth clamp element 32 from top to bottom through a washer.

[0033] Furthermore, in the present embodiment, the bead bin assembly 2 comprises a bead storage bin 21 and a bead supply motor 22. The bead storage bin 21 comprises an upper bin body and a lower bin body which are rotatably connected to each other. The upper bin body is mounted on the frame 1 through a bracket, the lower bin body is arranged on the output rotating shaft of the bead supply motor 22, the bead outlet is arranged on the upper bin body, and the upper end of the bead outlet wire 5 extends from the bead outlet into the upper bin body; the bead supply motor 22 drives the lower bin body to rotate at a high speed, so that the embroidery beads in the bead storage bin 21 roll centrifugally and the embroidery beads are strung onto the bead outlet wire 5 during the rolling process.

[0034] In this embodiment, the bead supply motor 22 and the lower bead driving motor are the same motor. The bead supply motor 22 drives the wheel shaft 33 to rotate synchronously through the transmission gear mechanism set on the frame 1, thereby controlling the operation of the lower bead control component 3.

[0035] However, the bead supply motor 22 can also directly drive the wheel shaft 33, and then indirectly drive the lower bin body to rotate through the gear transmission mechanism. In other embodiments, the bead supply motor 22 and the lower bead driving motor can also be a motor each.

[0036] Furthermore, in the present embodiment, a lifting assembly 6 is provided between the frame 1 and the external support structure. The lifting assembly 6 is tilted and is used to control the frame 1 and the three groups of bead embroidery mechanisms to rise obliquely as a whole, so that the lower end of the bead-outputting steel wire 5 is offset and away from the bead-feeding position of the bead-feeding assembly 4, thereby placing the entire bead embroidery device in a shutdown state where it cannot operate normally; the lifting assembly 6 can also cause the frame 1 and the three groups of bead embroidery mechanisms to descend obliquely as a whole, so that the lower end of the bead-outputting steel wire 5 accurately hovers above the bead-feeding position, so that the entire bead embroidery device is in a working position where it can operate normally.

[0037] In this embodiment, the lifting assembly 6 includes a lifting drive cylinder 61, a lifting sliding rail 62, and a lifting slide 63. The lifting slide 63 is fixedly arranged on the back of the frame 1, and the lifting slide 63 is arranged on the lifting sliding rail 62. The lifting drive cylinder 61 and the lifting sliding rail 62 are both fixedly installed on the external support structure. The lifting drive cylinder 61 is tilted, and the output telescopic shaft end of the lifting drive cylinder 61 is fixedly connected to the lifting slide 63.

[0038] In addition, the cross-section of the lifting and sliding rail 62 is set to be T-shaped, the corresponding slide groove of the lifting slide 63 is also T-shaped, and limited stop blocks or other structural forms of blocking structures are also set at both ends of the lifting and sliding rail 62 to prevent the lifting slide 63 from moving off the track.

[0039] It should be noted that the limit stopper or other blocking structures in other structural forms are not drawn in the figure, and the specific structural forms of the blocking structures can be regarded as prior art in the art.

[0040] Furthermore, in this embodiment, a transverse drive assembly 7 is also provided on the frame 1, and the transverse drive assembly 7 is provided above one side of the bead feeding assembly 4. The output end of the transverse drive assembly 7 is used to install a gold sheet feeding mechanism or other feeding mechanisms for providing materials to the needle position of the embroidery machine. Taking the installation of the gold sheet feeding mechanism at the output end of the transverse drive assembly 7 as an example, the transverse drive assembly 7 is used to drive the gold sheet feeding mechanism to move toward the needle position of the embroidery machine to provide gold sheet materials to the embroidery machine, so as to mix gold sheets between adjacent embroidery beads, so as to make the bead embroidery products at the embroidery machine more beautiful.

[0041] In this embodiment, the transverse drive assembly 7 includes a transverse drive motor 71, a transverse slide 72, a transverse track 73, and a transverse transmission mechanism. The transverse drive motor 71 and the transverse track 73 are both mounted on the frame 1. The transverse slide 72 is movably mounted on the transverse track 73. The sequin feeding mechanism is correspondingly mounted on the transverse slide 72. The transverse drive motor 71 drives the transverse slide 72 to move back and forth horizontally through the transverse transmission mechanism, thereby enabling the sequin feeding mechanism to provide sequins to the embroidery machine. The transverse transmission mechanism includes a first connecting rod 74 horizontally mounted on the output shaft of the transverse drive motor 71, a push rod 75 mounted at one end of the first connecting rod 74, and a toggle slot 76 disposed at the upper end of the transverse slide 72. The push rod 75 extends into the toggle slot 76. The push rod 75 performs a circular motion through the transverse drive motor 71 and the first connecting rod 74, and pushes the transverse slide 72 to move back and forth horizontally in the toggle slot 76.

[0042] It should be noted that in order to ensure that the transverse transmission mechanism can transmit power stably, the push rod 75 must always be in the toggle groove 76 during the process of making the circular origin. Therefore, the thickness of the transverse slide 72 is at least half the length of the first connecting rod 74; that is: the length of the toggle groove 76 in the front view direction is greater than or equal to the distance from the push rod 75 to the output shaft of the transverse drive motor 71.

[0043] Furthermore, in the present embodiment, since the reciprocating movement of the transverse slide 72 is realized by the forward and reverse rotation of the transverse drive motor 71, and in order to ensure that the transverse drive motor 71 does not rotate any more after rotating forward 180°, limit grooves 77 are provided on both sides of the toggle groove 76, and a limit rod 78 is provided at the other end of the first connecting rod 74. The distances between the two limit grooves 77 and the toggle groove 76 are equal to the distance between the limit rod 78 and the push rod 75. A protrusion is provided on the groove wall of the limit groove 77. Whenever the first connecting rod 74 rotates 180°, the limit rod 78 will rotate to a limit groove 77 and be blocked by the protrusion, thereby realizing the above-mentioned phenomenon of preventing the first connecting rod 74 from rotating more than 180°.

[0044] It should be noted that the gold sheet feeding mechanism is not shown in the drawings of this embodiment, and those skilled in the art are requested to consider the gold sheet feeding mechanism as prior art.

[0045] Anything not mentioned above is applicable to the prior art.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
