[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, this embodiment provides a reel-changing and tape-splicing device. Specifically, the reel-changing and tape-splicing device includes an unwinding mechanism 2, a guide member 3, a tape-splicing mechanism 6, and a driving mechanism 5.

[0038] like Figure 1 and Figure 2 As shown, the unwinding mechanism 2 is provided with a coil mounting portion 21. The coil mounting portion 21 is used for detachably mounting the coil 1. Specifically, the coil mounting portion 21 can be an inflation reel or a clamping reel. The splicing mechanism 6 is used to butt-connect the leading end of the new coil and the trailing end of the old coil.

[0039] like Figure 1 and Figure 2As shown, the belt connecting mechanism 6 is arranged on one side of the unwinding mechanism 2 in the belt feeding direction, the guide member 3 extends along the belt connecting mechanism 6 in the direction of the driving mechanism 5, the belt connecting mechanism 6 is slidingly arranged on the guide member 3, and the driving mechanism 5 is connected to the belt connecting mechanism 6. The driving mechanism 5 is used to drive the belt connecting mechanism 6 to slide along the guide member 3 so that the belt connecting mechanism 6 is close to or away from the unwinding mechanism 2.

[0040] like Figure 1 and Figure 2 As shown, when in use, according to the diameter of the coil 1, the driving mechanism 5 drives the splicing mechanism 6, and the guide member 3 provides guidance for the splicing mechanism 6. The splicing mechanism 6 slides on the guide member 3, thereby adjusting the distance between the splicing mechanism 6 and the unwinding mechanism 2, so that the splicing mechanism 6 remains in a suitable position. When the coil 1 is exhausted, the driving mechanism 5 provides power, and under the guidance of the guide member 3, the splicing mechanism 6 is moved closer to the unwinding mechanism 2, so that the splicing position is closer to the end of the tail of the old coil, reducing the running distance of the tail, thereby reducing the amount of scrapped tail pole pieces when changing coils, saving materials, and being economical.

[0041] like Figure 2 As shown, the drive mechanism 5 optionally includes a cylinder 51 and a piston 52. The piston 52 is slidably mounted on the cylinder 51 in a direction parallel to the extension of the guide member 3. The piston 52 is connected to the splicing mechanism 6. In other words, the piston 52 and the cylinder 51 cooperate to achieve linear reciprocating motion, thereby moving the splicing mechanism 6 toward or away from the unwinding mechanism 2 along a straight line. This provides a simple structure and high adjustment accuracy. In this embodiment, the cylinder 51 is positioned on the side of the splicing mechanism 6 away from the unwinding mechanism 2, and the piston 52 is slidably inserted into the cylinder 51. In other embodiments, the drive mechanism 5 can also be an electric telescopic rod, etc.

[0042] like Figure 2 and Figure 3 As shown, the tape connecting mechanism 6 optionally includes a support 62. A protrusion is provided on one of the support 62 and the guide member 3, and a guide groove is provided on the other. The protrusion and the guide groove slide together. The interlocking protrusion and the guide groove help ensure guiding accuracy and prevent dislocation. In this embodiment, the guide member 3 is a guide rail, and there are two guide rails spaced apart along the width of the tape. The lower end of the support 62 is provided with two guide grooves, which correspond one-to-one with the guide rails.

[0043] like Figure 1 and Figure 2As shown, the roll-changing and splicing device optionally further includes a material receiving and unloading mechanism 7, which is arranged on the side of the splicing mechanism 6 away from the unwinding mechanism 2 along the tape running direction. As the splicing mechanism 6 approaches or moves away from the unwinding mechanism 2, the length of the unwinding tape 4 fluctuates, and the length of the unwinding tape 4 on the side of the splicing mechanism 6 away from the unwinding mechanism 2 may be surplus or deficient. The material receiving and unloading mechanism 7 is located on this side of the splicing mechanism 6 and, depending on the position of the splicing mechanism 6, adaptively unloads or receives the material, thereby maintaining an appropriate tension on the unwinding tape 4 and preventing wrinkles or positional deviations.

[0044] like Figure 1 and Figure 2 As shown, the material receiving and unwinding mechanism 7 optionally includes a first roller 71, a second roller 72, and an adjusting roller 73. The first roller 71 and the second roller 72 are spaced apart horizontally, and the adjusting roller 73 is arranged between the first roller 71 and the second roller 72 with adjustable height. The unwinding belt 4 is sequentially wound around the first roller 71, the adjusting roller 73, and the second roller 72. The positions of the first roller 71 and the second roller 72 remain stationary, and changing the position of the adjusting roller 73 changes the amount of unwinding belt 4 stored in the material receiving and unwinding mechanism 7, thereby adjusting the tension of the unwinding belt 4. In this embodiment, the material receiving and unwinding mechanism 7 also includes a frame, and the first roller 71 and the second roller 72 are rotatably mounted on the frame and maintain a fixed position.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment, the material receiving and unloading mechanism 7 further includes a counterweight 74, which is disposed on an adjusting roller 73. The unwinding belt 4 rolls and supports the adjusting roller 73. As the length of the unwinding belt 4 between the first roller 71 and the second roller 72 changes, the height of the adjusting roller 73 adaptively changes under the action of the counterweight 74, thereby achieving automatic material receiving or unloading.

[0046] In another embodiment, the material receiving and unloading mechanism 7 further includes a position adjustment mechanism connected to the adjustment roller 73. The position adjustment mechanism provides power to change the position of the adjustment roller 73, thereby adjusting the material storage and supply of the unwinding belt 4. The specific type of the position adjustment mechanism is not limited, as long as it can achieve position change and maintain stability.

[0047] like Figure 3As shown, optionally, the tape splicing mechanism 6 includes a tape splicing platform 61, a first tape pressing member 63, and a second tape pressing member 64. The first tape pressing member 63 and the second tape pressing member 64 are spaced apart along the tape running direction and are both located above the tape splicing platform 61. The first tape pressing member 63 can press the unwinding tape 4 on the tape splicing platform 61, and the second tape pressing member 64 can press the unwinding tape 4 on the tape splicing platform 61. The first tape pressing member 63 and the second tape pressing member 64 are independent of each other and can move closer to or farther from the tape splicing platform 61, thereby pressing or releasing the unwinding tape 4. The first tape pressing member 63 and the second tape pressing member 64 are used to press the head of the new coil and the tail of the old coil, respectively, thereby facilitating the tape splicing operation on the tape splicing platform 61.

[0048] like Figure 1 As shown, the splicing mechanism 6 optionally further includes a first guide roller 65 and a second guide roller 66. The first guide roller 65 is disposed on a side of the first belt-holding member 63 away from the second belt-holding member 64, and the second guide roller 66 is disposed on a side of the second belt-holding member 64 away from the first belt-holding member 63. After passing through the first guide roller 65, the unwinding tape 4 enters between the first belt-holding member 63 and the splicing platform 61. After passing between the second belt-holding member 64 and the splicing platform 61, the unwinding tape 4 is output through the second guide roller 66. The first guide roller 65 and the second guide roller 66 respectively provide guidance for the unwinding tape 4 entering and exiting the splicing mechanism 6 to prevent damage to the unwinding tape 4.

[0049] like Figure 2 As shown, optionally, the belt splicing mechanism 6 further includes a first telescopic member 67 that is telescopic in the height direction, the first telescopic member 67 being disposed on the belt splicing platform 61, and the first belt pressing member 63 being disposed on the first telescopic member 67. The first telescopic member 67 drives the first belt pressing member 63 to move up and down, thereby enabling the first belt pressing member 63 to press or release the unwinding belt 4. Similarly, the belt splicing mechanism 6 further includes a second telescopic member 68 that is telescopic in the height direction, the second telescopic member 68 being disposed on the belt splicing platform 61, and the second belt pressing member 64 being disposed on the second telescopic member 68. Both the first telescopic member 67 and the second telescopic member 68 may be telescopic rods, telescopic cylinders, or the like.

[0050] like Figure 3As shown, optionally, the tape splicing platform 61 is provided with a first telescopic member 67 at both ends in the tape running width direction, the first tape pressing member 63 includes a first pressure rod, and the two ends of the first pressure rod are respectively arranged on the two first telescopic members 67. The tape splicing platform 61 is provided with a second telescopic member 68 at both ends in the tape running width direction, and the second tape pressing member 64 includes a second pressure rod, and the two ends of the second pressure rod are respectively arranged on the two second telescopic members 68. The first pressure rod is suspended above the tape splicing platform 61 by the two first telescopic members 67, and the second pressure rod is suspended above the tape splicing platform 61 by the two second telescopic members 68, thereby providing a passage for the unwinding tape 4 to pass through. The two ends of the first pressure rod are driven separately by the two first telescopic members 67, which helps the first pressure rod to evenly press the unwinding tape 4. The two ends of the second pressure rod are driven separately by the two second telescopic members 68, which also helps the second pressure rod to evenly press the unwinding tape 4.

A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
