Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a fabric splicing device. Background Technology

[0002] A fabric splicing device is a key auxiliary device used in continuous roll (fabric or sheet) production or processing equipment in textiles, nonwovens, papermaking, and plastic films. Its core function is to connect new and old rolls of material (cloth rolls, paper rolls, film rolls, etc.) without interrupting the operation of the entire production line.

[0003] Traditional fabric splicing devices rely on operators' visual observation of the remaining fabric roll or experience to determine when to initiate the splicing process. This method is prone to delays, subjectivity, and fatigue-related misjudgments, easily leading to idle runs and material shortages. If the splicing action is initiated too late (e.g., due to human error or delayed response), the tail of the old fabric roll may completely detach from the unwinding shaft or pass through critical process areas (such as ovens and rollers), resulting in an "idling" state with no fabric passing through the production line. This inevitably causes downtime, and the efficiency of re-threading and re-feeding is extremely low, and waste products are easily generated during the recovery process. Utility Model Content

Combined with the new roll preparation status provided by the gravity module, the controller can reserve sufficient safety margin time before the fabric is exhausted, accurately initiating the fabric receiving process, thus achieving automation, objectivity, and precision in the roll change trigger signal.

[0030] This embodiment of the invention improves the structure of the first fabric support frame, enabling it to monitor the remaining amount of fabric flow in real time.

[0031] Specifically, the frame 1 is provided with the fabric receiving assembly 2, the upper part of the fabric receiving assembly 2 is provided with a guide roller 11, and the lower part of the fabric receiving assembly 2 is provided with the first fabric support frame 3;

The weighing sensor is provided on the driven roller 31. Multiple driven rollers 31 form a driven roller group. The active roller 32 is located on both sides of the driven roller group. The active roller 32 can contact the fabric and drive the fabric to rotate in a predetermined direction. A photoelectric sensor is also provided on the active roller 32.

[0033] The fabric receiving device of this utility model includes a frame 1, a fabric receiving assembly 2, and a first fabric support frame 3. The first fabric support frame 3 includes an active roller 32, a driven roller 31, and a weighing sensor. The driven roller 31 is equipped with a weighing sensor, and multiple driven rollers 31 have active rollers on both sides. The active roller 32 can contact the fabric and drive it to rotate in a predetermined direction. The active roller 32 is also equipped with a photoelectric sensor. Because of the weighing sensor on the driven roller 31 and the photoelectric sensor on the active roller 32, the remaining amount of fabric can be monitored in real time. The weighing sensor continuously monitors the weight of the new fabric roll placed on the first fabric support frame 3, while the photoelectric sensor on the active roller 32 detects whether the fabric is exhausted. When the end of the old fabric is about to completely leave, but has not yet completely left the controllable area, a signal indicating impending exhaustion is sent to the controller. Combined with the new roll preparation status provided by the gravity module, the controller can reserve sufficient safety margin time before the fabric is exhausted, accurately initiating the fabric receiving process, thus achieving automation, objectivity, and precision in the roll change trigger signal.

[0034] In some embodiments, the fabric splicing assembly 2 includes a track mounting frame 21, a fabric splicing machine 22, a pneumatic clamp 23, a fabric pressing device 24, and a pressure plate assembly 25;

[0035] The front side of the track mounting frame 21 is provided with a fabric receiving machine track 211, and the fabric receiving machine 22 is slidably connected on the fabric receiving machine track 211. The track mounting frame 21 is also provided with two fabric pressing devices 24 with a predetermined distance, and the pneumatic clamp 23 is provided between the two fabric pressing devices 24.

[0036] The pressure plate assembly 25 includes a cylinder 251 and a pressure plate 252. The cylinder 251 is provided at both ends of the track mounting frame 21. The pressure plate 252 is connected between the push rods of the cylinder 251. The cylinder 251 can drive the pressure plate 252 to move closer to or away from the track mounting frame 21.

[0037] During fabric splicing, the fabric pressing device 24 first presses and positions both sides of the fabric, the pneumatic clamp 23 clamps one side of the fabric, and the pressure plate 252 of the pressure plate assembly 25, driven by the cylinder 251, presses the fabric. After pressing and positioning are completed, the fabric splicing machine starts and slides along the track mounting frame to splice and cut the fabric.

[0038] First, the pneumatically coordinated positioning of the fabric pressing device 24 and the pneumatic clamp 23 applies symmetrical pressure to both sides of the fabric, eliminating lateral displacement. The pneumatic clamp 23 holds the fabric edge on one side, solving the problem of edge escape in thin / slippery fabrics. Second, the fabric splicing machine 22 slides along the track, ensuring a high degree of straightness and no deviation in the cutting trajectory, avoiding wavy edges caused by manual operation.

[0043] More preferably, the cylinder mounting bracket 242 is provided with a friction part 244 with a corrugated structure below the pressure block 243. The friction part 244 can increase the friction between the pressure block 243 and the fabric, and prevent the fabric from slipping.
