Description

Technical Field

[0001] This utility model relates to the field of textile processing equipment technology, and in particular to a multi-sided labeling mechanism for longitudinal sewing machines. Background Technology

[0002] In the finishing process of textiles, various labels need to be sewn into specific locations, such as flat labels sewn on a flat surface, folded labels (also called loop labels) sewn after folding, and loop labels with loops. Currently, most label sewing processes rely on manual label placement or the use of single-function automatic label feeding equipment. This leads to the following problems: manual label placement is slow and inaccurate, making it difficult to match the pace of modern high-speed sewing machines. If single-function label feeding equipment cannot adapt to the diverse label types required by different textile styles, changing label types often requires machine downtime for adjustments or mold replacements, affecting production continuity.

[0003] Therefore, there is an urgent need in this field for an automated label delivery mechanism that can automatically, quickly, and accurately deliver various types of sewing labels and can be seamlessly integrated with high-speed sewing equipment. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a multi-side labeling mechanism for longitudinal sewing machines, which can integrate the automatic conveying and precise delivery of straight labels, ring labels and ear loop labels, effectively improving the efficiency and quality of the label sewing process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: The longitudinal sewing machine has multiple labeling mechanisms on the side, including a straight label and ring label conveying device, an ear tag conveying device, and a label belt conveying device. The straight label and ring label conveying device and the ear tag conveying device are arranged vertically, and the shared label belt conveying device is located on one side for label conveying.

[0006] A further improvement is that the straight and ring label conveying device includes a label tray, a straight module, a label feeding head, a guide plate, and a label cutting shear. The vertical guide plate has a long groove for the label direction. The label feeding head abuts against the long groove and is connected to a label pressing cylinder. The label pressing cylinder seat is connected to the slider of the straight module. The label cutting shear is located on one side of the rear end of the guide plate. The label tape led out from the label tray travels through the guide plate. The label feeding head presses against the label in the long groove and moves forward. After the label belt conveyor clamps the label, the label cutting shear cuts the label.

[0007] A further improvement is to install a label folder on one side of the rear end of the label guide plate, which is used to fold the front end of the label tape into a folded ring label. When a folded label needs to be made, the label folder can be activated to fold the front end of the label tape into a folded structure, which is then delivered by the label feeding head.

[0008] A further improvement is that the ear tag conveying device includes a label tray two, a label clamping assembly, a linear module two, a label pulling clamp, a label feeding assembly, and a label cutting shear two. The linear module two is upright, and the label clamping assembly is located on one side of its bottom, used to clamp the front end of the label tape leading out from the label tray two. The label clamp is connected to the slider of the linear module two and is used to pull the front end of the label tape upward. The label feeding assembly is located between the label clamp and the label belt conveyor. The label feeding assembly includes a push cylinder, an upper clamping flip clamp, and a lower clamping flip clamp. The mounting bases of the upper clamping flip clamp and the lower clamping flip clamp are connected to the telescopic rod of the push cylinder. Under the action of their gripper cylinders, the upper clamping flip clamp and the lower clamping flip clamp respectively clamp the upper and lower positions of the front part of the label tape. The label cutter two cuts the label tape held below by the lower clamping flip clamp. The upper clamping flip clamp and the lower clamping flip clamp are provided with triangular folding plates. Under the action of their flip cylinders, they are flipped 90 degrees to form ear tags. The push cylinder pushes the upper and lower clamping flip clamps to send the ear tags to the label belt conveyor.

[0009] A further improvement is that the label belt conveyor includes pulleys installed on the upper and lower parts of the vertical side plate, a vertical clamping plate is provided on one side of the vertical side plate, a section of belt on the pulley is located in the vertical clamping plate, and notches are opened on the vertical clamping plates at the corresponding positions of the label conveying devices for straight labels and ring labels and the label conveying device for ear tags. Pushing cylinders are installed at the corresponding positions on the vertical side plate, and the front end of the telescopic rod of the pushing cylinder is connected to a movable wall plate, which fits into the notch.

[0010] A further improvement is that a label-returning cylinder is also provided below the push-wall cylinder, and a label-pressing plate is connected to the front end of the telescopic rod of the label-returning cylinder. When the label is fed in, the label-pressing plate gently presses against the label to prevent it from retracting or shifting due to vibration or inertia during transmission, thus ensuring the accuracy of the delivery position.

[0011] Beneficial effects: 1. High integration and flexibility of functions: Through modular design, the preparation and delivery functions of three common sewing labels are integrated into one, and the label type can be quickly switched according to production instructions, which greatly enhances the flexibility of the production line and adapts to the modern production mode of small batch and multiple varieties.

[0012] 2. Fully automated and highly efficient: The entire process from label pulling, forming, cutting to delivery is fully automated, working perfectly with high-speed sewing machines, significantly reducing manual intervention and improving overall production efficiency.

[0013] 3. High delivery accuracy and good sewing quality: The label belt conveyor delivery device ensures that the labels do not slip or wrinkle during delivery through a precisely controllable access window and anti-rebound design, ultimately guaranteeing that the labels sewn onto the textiles are uniformly positioned, flat and beautiful.

Detailed Implementation

[0015] like Figure 1 As shown, this utility model mainly consists of three parts: the upper straight label and ring label conveying device 1, the lower ear tag conveying device 2, and the label belt conveying device 3 located to their right. The straight label and ring label conveying device 1 and the ear tag conveying device 2 share the label belt conveying device 3 for label receiving and conveying.

[0016] Combination Figure 2 As shown, the label conveying device 1 includes a label plate 11, a linear module 12, a label feeding head 13, a label guide plate 14, and a label cutter 15 (not fully shown in the figure). The two vertically erected label guide plates 14 form a travel path for the label tape. A long groove for the label direction is opened on the outer label guide plate 14. The label feeding head 13 abuts against the long groove and is connected to the label pressing cylinder. The label pressing cylinder seat is connected to the slider of the linear module 12. The label cutter 15 is located on one side of the rear end of the label guide plate 14. The label tape led out from the label plate 11 passes through the label guide plate 14. The label feeding head 13 presses the label tape under the action of the label pressing cylinder. Then, the linear module 12 drives the slider forward, pushing the label tape in the long groove forward. The belt conveyor 3 clamps the label. The label cut by the label cutter 15 is the label. A label folder 16, which can be driven by a small cylinder, is provided on one side of the rear end of the label guide plate 14. When it is necessary to produce folded ring labels, the label folder 16 first moves to push and fold the front end of the label tape to make it folded in half, and then it is sent out by the label feeding head 13. After the front of the label tape is clamped by the label belt conveyor 3, the label cutter 15 moves to cut the label off the label tape.

[0017] Combination Figure 3As shown, the tag conveying device 2 includes a tag tray 21, a tag clamping assembly 22, a linear module 23, a tag puller 24, a tag feeding assembly 25, and a tag cutter 26. The linear module 23 is installed vertically, with the tag clamping assembly 22 located on one side of its bottom. During operation, the front end of the tag tape extending from the tag tray 21 is first clamped by the tag clamping assembly 22. The tag puller 24 is connected to the slider of the linear module 23. Then, the tag puller 24 descends to clamp the front end of the tag tape, and under the drive of the linear module 23, it ascends to pull the tag tape to a predetermined length. The tag feeding assembly 25 is located between the tag puller 24 and the tag belt conveyor 3. The tag feeding assembly 25 includes a push cylinder 251, an upper clamping and flipping clamp 252, and a lower clamping and flipping clamp 253. The mounting bases of the upper clamping and flipping clamp 252 and the lower clamping and flipping clamp 253 are connected to the telescopic rod of the push cylinder 251. Subsequently, the upper clamping flip clamp 252 and the lower clamping flip clamp 253, under the action of their respective gripper cylinders, clamp the upper and lower parts of the stretched label tape respectively. The label cutter 26 then actuates, cutting the label tape held below by the lower clamping flip clamp 253. Then, driven by their respective flipping cylinders, the upper clamping flip clamp 252 and the lower clamping flip clamp 253 rotate inward 90 degrees together with the clamped label segment. The triangular folding plates on the clamps fold the label segment into a hanging ear tag. Finally, the push cylinder 251 pushes the upper and lower clamping flip clamps to move the hanging ear tag forward, sending the made hanging ear tag to the label belt conveyor 3.

[0018] like Figure 4 As shown, the label belt conveyor 3 includes pulleys 32 installed on the upper and lower parts of the vertical side plate 31. A vertical clamping plate 33 is provided on one side of the vertical side plate 31. A section of belt winding around the pulley is located in the vertical clamping plate 33. Notches 34 are respectively cut into the vertical clamping plates 33 at the corresponding positions of the straight label and ring label conveying devices and the ear tag conveying devices. Push-wall cylinders 35 are respectively installed at corresponding positions on the vertical side plate 31. The front end of the telescopic rod of the push-wall cylinder 35 is connected to a movable wall plate 36, which engages with the notches 34. Figures 1 to 4 When a label is delivered by the straight label / ring label conveyor 1 or the ear tag conveyor 2, the corresponding push-wall cylinder 35 extends its telescopic rod, causing the movable wall plate 36 to retract, leaving a window for the label to connect on the vertical clamping plate 33. Upon receiving the label, the push-wall cylinder extends, pushing the movable wall plate 36 forward to close the window, clamping the label, and working with the conveyor belt to clamp and transport the label. Below the push-wall cylinder, a label-returning cylinder 37 is also provided. The front end of the telescopic rod of the label-returning cylinder 37 is connected to a label-pressing plate 38, which serves to stop and position the label when it enters the window.
