Detailed Implementation

[0027] like Figures 1-8 As shown, the present invention includes a frame 1, on which a label tray 2 is rotatably mounted, and a roll of label tape 3 is mounted on the label tray 2. The frame is also equipped with a label tape clamping and conveying device, a cutting device, a label folding device, and a detection device 17 for detecting label dividing lines.

[0028] A support plate 4 for supporting the label tape 3 is installed on the frame 1. The conveying device includes a drive roller 5 and a driven roller 6, which are arranged vertically opposite each other and on the upper and lower sides of the support plate 4. The support plate 4 has clearance grooves to avoid the drive roller or the driven roller. The drive roller 5 is driven by a motor 7, and the frame 1 is equipped with a lubrication device 18 for adding oil to the motor. In this embodiment, the driven roller 6 is placed on top, which facilitates placing the motor 7 at the bottom of the frame and makes the equipment layout easier. An elastic element 8 (such as a compression spring) is provided between the driven roller 6 and the frame 1 to cause the driven roller 6 to abut against the drive roller 5, thereby clamping the label tape between the drive roller 5 and the driven roller 6. The motor 7 drives the drive roller 5 to convey the label tape to the cutting device side. A guide plate 9 is provided above the support plate 4. There is an interval between the guide plate and the support plate for the label tape to pass through. The front end of the guide plate 9 is inclined. A clearance groove for avoiding the driven roller is provided on the guide plate 9. If the driving roller is set above, the clearance groove is used to avoid the driving roller.

[0029] The cutting device is installed at the rear end of the support plate 4 and includes a fixed blade 10 and a movable blade 11. The movable blade 11 is driven by a first drive mechanism 12. The first drive mechanism 12 is a cylinder that drives the movable blade 11 to move up and down to cut the label tape.

[0030] The label folding device includes a fixed plate 13 and a movable plate 14 located at the exit of the label cutting device. The movable plate 14 is driven by a second drive mechanism 16, which can be a cylinder. The movable plate 14 has a lower through hole 14.1 and an upper through hole 14.2. A protrusion 14.3 is provided between the upper through hole 14.2 and the lower through hole 14.1, protruding towards the fixed plate 13. The fixed plate 13 has a groove 13.1. Figure 3 , 5, 6, 7, 8, in the initial state, the protrusion 14.3 is separated from the groove 13.1 of the fixed plate, the lower through hole 14.1 is aligned with the outlet of the label cutting device, the lower through hole 14.1 is used as a pressing channel for the label strip 3 to pass through, when the label strip 3 passes through the pressing channel, the second driving mechanism drives the movable plate to move downward, the protrusion 14.3 presses the end of the label strip in the groove 13.1, at this time, the upper through hole 14.2 is aligned with the outlet of the label cutting device, the upper through hole 14.2 is used as a folding channel for the label strip 3 to pass through, at this time, the label strip 3 passes through the folding channel to realize folding, and the inner wall surface of the upper through hole promotes the label strip to be folded more easily. In order to make the protrusion and the groove cooperate more closely, an elastic mechanism (such as a spring) can be arranged to promote the movable plate and the fixed plate to abut together, the movable plate 14 of the embodiment is connected with the second driving mechanism 16 through the elastic hinge 15, the elastic hinge 15 plays a connecting role on the one hand, and promotes the movable plate 14 and the fixed plate 13 to abut on the other hand. From Figure 7 It can be seen that the bottom surface of the movable plate and the upper surface of the fixed plate abut together, which can play a certain guiding role.

[0031] From Figure 7 , 8 It can be seen that the fixed plate 13 of the embodiment is arranged below, the movable plate is located above the fixed plate on the side, and the fixed plate is located below the side. As shown in Figure 9 , the fixed plate 13 can also be moved from the position of Figure 7 to the side above the movable plate 14, at this time, the upper through hole 14.2 is used as a pressing channel for the label strip to pass through in the initial position, the protrusion is arranged below the upper through hole 14.2, after the label strip passes through, the movable plate is driven to move upward, the protrusion can also press the end of the label strip in the groove, at this time, the movable plate as a whole moves to the position above the outlet of the cutting device, then, the space below the movable plate becomes a folding channel, and the movable plate does not hinder the label strip. Obviously, the lower through hole 14.1 can also be retained, when the movable plate moves upward, the protrusion presses the end of the label strip, and the lower through hole 14.1 moves to the corresponding position of the outlet of the label cutting device to become a folding channel for the label strip to pass through.

[0032] Taking the structure shown in Figure 2 as an example, the specific working process of the embodiment is as follows:

[0033] The detecting device 17 starts timing after detecting the label dividing line, and after a period of time, when the end of the label tape passes through the fixed plate 13, through the lower through hole 14.1 by a certain length (the label tape is folded down to reach the groove of the fixed plate), the second driving mechanism 16 drives the movable plate 14 to move downward, the upper edge of the lower through hole 14.1 promotes the label tape to fold downward, when the protrusion 14.3 of the movable plate 14 is clamped into the groove 13.1 of the fixed plate 13, the end of the label tape is fixed between the fixed plate 13 and the movable plate 14, at this time, the upper through hole 14.2 is aligned with the outlet of the cutting device. The label tape continues to be conveyed for a period of time, since the end of the label tape is fixed, so that the label tape forms a double-layer folded shape and passes through the upper through hole 14.2, a clamping device (not shown in the embodiment) such as a mechanical hand can clamp the folded label, the first driving mechanism acts to cut off the label. After cutting, the second driving mechanism drives the movable plate to move upward to return to the initial state, and the lower through hole 14.1 is aligned with the outlet of the cutting device.

[0034] The present application can be used for folding and cutting of labels in the conventional sense, and can also be used for folding and cutting of cloth, therefore, the label described in the claims and description of the present application should be understood in a broad sense, and is not limited to the "label" sewn on clothes for displaying the composition of the clothes cloth and washing instructions.
