[0033] Reference Figures 1 to 4As shown, the present embodiment provides a tape reel device 100 for tape embroidery, including a tape reel support 10, wherein the tape reel support 10 is provided with at least two tape reel mounting positions for mounting a tape reel 13 along the circumferential direction. The figure shows that two tape reels 13 are installed. Of course, each tape reel support can also be provided with a tape reel mounting position, and multiple tape reel supports can be combined. Among them, a rotating shaft 131 is provided at the center of the tape reel 13, and a material storage trough 132 for storing a material tape roll is provided around the circumference of the tape reel 13. The material tape roll is not shown in the figure here. In the prior art, after the tape reel 13 is installed in the tape reel mounting position of the tape reel support 10, there is still a possibility of movement due to the lack of additional restrictions, resulting in unstable installation of the tape reel and easy loosening. In order to solve the problem of unstable installation of the tape reel and easy loosening, a tape reel locking mechanism 11 is provided at the corresponding tape reel mounting position, and the tape reel locking mechanism 11 fixes the tape reel 13 to the tape reel mounting position.

[0034] In some embodiments, the reel locking mechanism 11 includes:

[0035] The shaft mounting groove 1011, two of the shaft mounting grooves 1011 are arranged side by side on the reel bracket 10, and the shaft mounting groove 1011 has an opening, and both ends of the rotating shaft 131 are respectively supported in the two shaft mounting grooves.

[0036] The rotating shaft 131 enters and exits the shaft installation slot through the opening, which facilitates the installation, removal and replacement of the reel.

[0037] The locking member 111 is used to lock the opening and restrict the rotating shaft 131 in the shaft installation groove 1011 .

[0038] Due to the restriction of the locking member on the rotating shaft, the rotating shaft can be prevented from moving in the shaft installation groove during operation, and the reel is installed stably and is not easy to loosen.

[0039] In order to facilitate the operation of the locking member, the locking member 111 is connected to a slide rail structure, and the slide rail structure guides the locking member 111 to move so as to lock or open the opening.

[0040] Specifically, the locking member 111 may be a locking rod, that is, a long rod-shaped structure, the locking rod is provided with a guide groove 1111, and the slide rail structure includes a guide pin connected to the guide groove 1111. Of course, it is understandable that the locking member may also be in other shapes.

[0041] Furthermore, the slide rail structure also includes a guide pressure plate 112, the guide groove 1111 is provided between the guide pressure plate 112 and the reel support 10, and the guide pin movably passes through the guide groove 1111, one end of which is connected to the reel support and the other end is connected to the guide pressure plate 112. The two sides of the guide groove 1111 are limited by the guide pressure plate 112 and the reel support and guided by the guide pin, so the locking rod can only move linearly, that is, move away from the shaft installation slot opening or move closer to the shaft installation slot opening to lock the opening or open the opening. Of course, it can be understood that the slide rail structure can also be replaced by other conventional structures.

[0042] Specifically, the reel support 10 is provided with two first support arms 101 arranged side by side on both axial sides of the reel 13, and an axle mounting groove 1011 cooperating with the rotating shaft 131 is provided at the end of the first support arm 101. The axle mounting groove 1011 can adopt a U-shaped structure, having a bottom wall, a first side edge and a second side edge, the rotating shaft 131 is supported on the bottom wall, and the two sides are limited by the first side edge and the second side edge, and the height of the first side edge is higher than the second side edge. Since the first support arm extends obliquely downward, the axle mounting groove is provided at the obliquely downward part of the first support arm, and the first side edge is located at the obliquely upward side of the first support arm, and the height formed is higher than the second side edge, which facilitates the installation and disassembly of the reel, because in this way the rotating shaft can easily enter the axle mounting groove from the opening, and can also be easily disengaged. In addition, the locking rod is located on the outside of the first support arm, and the inclination angle is consistent with that of the first support arm.

[0043] Furthermore, the reel locking mechanism 11 also includes a transmission rod 114 hinged to the reel bracket, and the transmission rod 114 is provided with a controlled part 1141 and a transmission part 1142 on opposite sides of the hinge fulcrum, and the transmission part 1142 is connected to the locking member 111. After the controlled part is controlled, the transmission rod rotates around the hinge fulcrum, so that the transmission part drives the locking member to move. In addition, the transmission part 1142 is provided with a waist-shaped groove 1144, and the tail end of the locking member is connected with a transmission pin 113, and the transmission pin 113 cooperates with the waist-shaped groove 1144. Since the guide pin cooperates with the guide groove 1111 for guidance, the locking member can only move linearly, and since the transmission pin 113 cooperates with the waist-shaped groove 1144, the transmission pin 113 can move along the waist-shaped groove, so that the rotation of the transmission rod 114 can be converted into the linear movement of the transmission pin 113, and then the transmission pin 113 drives the locking member 111 to move linearly.

[0044] There is an angle between the controlled part 1141 and the transmission part 1142, which is roughly V-shaped. The transmission rod is connected to a fulcrum pin 1143 at the corresponding hinge fulcrum (i.e., the position where the controlled part 1141 and the transmission part 1142 are connected). In addition, the fulcrum pin 1143 is connected to a reset torsion spring, which connects the transmission rod and the reel bracket. Therefore, after the controlled part is released from control, the reset torsion spring drives the transmission rod to rotate and reset. When the transmission rod rotates and resets, it drives the locking member to reset and lock the opening.

[0045] Furthermore, the head end of the locking member 111 is provided with a locking inclined surface 1112 which is pressed against the rotating shaft when the opening is locked. The head end of the locking member 111 not only closes the opening of the shaft installation groove, but also presses and fixes the rotating shaft by the locking inclined surface 1112. In this way, even if the diameter of the rotating shaft changes, the locking inclined surface 1112 can still press and fix the rotating shaft, and at the same time has the advantage of reliable fixation.

[0046] The tape roll is arranged circumferentially around the material storage slot 132. When the tape is coiled, the tape is pulled out from the tape roll. In the prior art, the tape roll is not limited, and the tape is easy to loosen, affecting the stable transportation of the tape. Therefore, a tape reel pressing mechanism 12 can be provided to press the outer ring of the tape roll to prevent the tape from loosening.

[0047] In some embodiments, the reel pressing mechanism 12 includes:

[0048] A flip member 122, wherein the flip member 122 is hingedly mounted on the reel support 10;

[0049] A belt pressing member 121, wherein the belt pressing member 121 is connected to the flip member 122, and the belt pressing member 121 is provided with a belt pressing portion 1211 pressed on the material belt roll in the material storage tank;

[0050] The elastic member is connected between the flip member and the tape reel bracket, and drives the flip member to drive the tape pressing member to rotate, so that the tape pressing part is elastically pressed onto the tape roll in the material storage tank.

[0051] The tape pressing part of the tape pressing member 121 of the tape reel pressing mechanism 12 is elastically pressed on the tape roll in the material storage tank, which does not affect the normal rotation of the tape reel, so that the tape can be normally output. At the same time, damping can be provided to the tape roll, and even if the tape reel rotates, the tape on the outer ring of the tape roll remains stable due to the elastic pressing effect, thereby achieving the technical effect of preventing the tape from loosening.

[0052] Specifically, the flip member 122 is provided with an axial hole portion 1222, and the axial hole portion 1222 is connected to the flap shaft 123. The end of the flap shaft passes through the axial hole portion and is rotatably supported on the reel bracket. Therefore, the rotating shaft is fixed to the axial hole portion, and the flip member and the tape pressing member rotate synchronously with the rotating shaft. The elastic member is a tension torsion spring, and the tension torsion spring has a first leg and a second leg, and the first leg and the second leg are connected to the flip member and the reel bracket respectively.

[0053] Furthermore, the reel pressing mechanism 12 further includes a tension adjusting wheel 124 for adjusting the deformation of the tension torsion spring to adjust the pressing force of the tape pressing member. The tension adjusting wheel is threadedly connected to the reel bracket and is provided with a tension adjusting portion connected to the tension torsion spring. The outer circle of the tension adjusting wheel is provided with an outer gear ring 1241 to facilitate the rotation of the tension adjusting wheel. The specific structure and adjustment principle can also refer to the prior art.

[0054] Specifically, the reel support 10 includes second support arms 102 arranged side by side on both sides of the reel axis, and the two ends of the flap shaft 123 are correspondingly supported by the second support arms 102 on both sides. The belt pressing member 121 is a belt pressing plate, and the belt pressing portion is arranged at the front of the belt pressing plate and located inside the material storage tank. Its width basically covers the outer ring of the material roll, but there is a gap with the second support arms 102 on both sides, so it can move freely and press the outer ring of the material roll. Lugs 1213 are arranged on both sides of the rear part of the belt pressing plate, and the lugs 1213 are connected to the flip member 122, and the flip member is provided with a connecting portion 1221 connected to the lugs. A notch 1212 is arranged in the middle of the rear part of the belt pressing plate.

[0055] When replacing the tape reel, the tape pressing plate must be turned outward to release the action between the tape pressing member and the tape roll. At the same time, the tape reel locking mechanism 11 also needs to be unlocked so that the rotating shaft can be moved out of the opening of the shaft mounting groove. Both actions are indispensable. If they are operated separately, two people are required to cooperate. Here, for the convenience of operation. The two actions can be linked, that is, the action of turning the tape pressing plate outward can drive the transmission rod 114 at the same time. A linkage structure is provided between the transmission rod 114 and the flip member 122. Specifically, the transmission rod 114 is provided with a transmission bearing 1146, which is located on one side of the controlled part 1141 and is installed on the bearing pin 1145. The flip member 122 is provided with a cam portion 1223, and the cam portion and the connecting portion 1221 are spaced apart on the circumferential outer side of the shaft hole portion 1222. The cam surface of the cam portion 1223 and the transmission bearing 1146 act in a positive direction to drive the flip member 122 to rotate. In this way, when replacing the tape reel, the tape pressing plate is turned outward, and the locking member can be driven to move through the linkage structure between the transmission rod 114 and the flip member 122, so that the tape reel locking mechanism 11 is unlocked. After the tape reel is replaced, the external force is released, and the flip member 122 and the tape pressing plate return to their original positions under the action of the tension torsion spring, and the cam surface of the cam portion 1223 and the transmission bearing 1146 act in the opposite direction. At the same time, due to the action of the reset torsion spring, the transmission rod 114 drives the locking member to return to its original position, and the tape reel locking mechanism 11 is also locked at the same time. In this way, there is no need to operate the tape reel pressing mechanism and the tape reel locking mechanism separately.

[0056] In addition, in the prior art, manual inspection is performed to check whether the remaining material of the tape roll on the tape reel is sufficient. In some embodiments, a tape reel remaining material detection mechanism may be provided. For example, the tape reel remaining material detection mechanism includes an angle sensor 103. According to the above description, the tape pressing member is used to press the tape roll in the material storage tank, and will rotate a corresponding angle when the remaining material of the tape roll changes. Therefore, the angle sensor 103 is used to detect the rotation angle of the tape pressing plate to obtain the remaining material data of the tape roll according to the rotation angle of the tape pressing plate.

[0057] As the remaining material of the tape roll on the reel decreases, the outer diameter of the entire tape roll decreases, and the belt pressing plate rotates closer to the center of the reel, so the angle of the belt pressing plate changes. In this way, the angle sensor detects the rotation angle of the belt pressing plate, and the remaining material data of the tape roll can be obtained according to the rotation angle of the belt pressing plate. This is not only more intuitive, but also more accurate.

[0058] Specifically, the angle sensor 103 is installed on the second support arm 102 , and can specifically detect the rotation angle of the shaft hole portion 1222 .

[0059] Since the angle sensor needs power to work, it is necessary to ensure that the power supply of the angle sensor is always stable. The reel bracket is installed on the M axis and rotates with the M axis, so it is difficult to directly lead the wire from the reel bracket. Therefore, a brush assembly 14 connected to the M axis is installed on the reel bracket, and the angle sensor is powered by the conductive function of the brush assembly 14.

[0060] Referring to the structure of the brush in the prior art, the brush assembly 14 includes a brush holder 144 and an electric ring inner cylinder 141, the electric ring inner cylinder 141 is installed on the M shaft, the brush holder 144 is arranged on the radial outer side of the electric ring inner cylinder, the electric ring inner cylinder 141 is connected to the angle sensor 103, and the brush holder is in contact with the electric ring inner cylinder for power supply. Specifically, an electric ring 142 is arranged on the electric ring inner cylinder, and the brush holder 144 is provided with an arc groove 145 facing the electric ring inner cylinder, corresponding to the outer circular shape of the electric ring inner cylinder, and a contact rod 146 is arranged on the arc groove, and the contact rod 146 is in contact with the electric ring 142 for electrical conduction. In addition, since the electric ring inner cylinder 141 rotates with the M shaft, a key groove 143 is provided, and the electric ring inner cylinder is connected to the M shaft by a key.

[0061] It can be understood that, in the present embodiment, part of the structure of the tape reel device is described, and other structures can refer to the prior art.

[0062] It can be understood that the tape reel device in this embodiment is applied to a tape embroidery machine, and is specifically arranged on a tape embroidery machine head. Other structures of the tape embroidery machine head and the tape embroidery machine can refer to the prior art.

[0063] The above is only a specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
