Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, and in particular to a gauze cutting device. Background Technology

[0002] Medical gauze is a commonly used treatment item in hospitals. People usually wrap medical gauze around the surface of wounds to prevent germs from entering and infecting the wound.

[0003] Patent No. CN202210694987.6 discloses an automatic fixed-length fabric cutting machine, relating to the field of fabric production and processing technology. This utility model includes a main board, a secondary board, and a stabilizing base. A conveyor belt is installed between the main board and the secondary board. A slot and groove are provided on one surface of the main board. A torsion spring is installed on the upper surface of the stabilizing base, and a threaded column is installed on the upper surface of the torsion spring. A threaded rod is threadedly connected to the inner circumferential side of the threaded column. A placement block is installed on the upper surface of the threaded rod, and a support plate is installed on one surface of the placement block. A cutting blade is installed on the lower surface of the support plate. Gears are fixedly installed on the circumferential side of the threaded column, and several partial racks are fixedly installed on one surface of the conveyor belt. This utility model uses the conveyor belt to drive the partial racks to move, which in turn drive the gears to rotate, thereby driving the threaded column to rotate. The threaded column, in turn, causes the torsion spring to tighten, while simultaneously driving the threaded rod downwards. The threaded rod, through the placement block and the support plate, drives the cutting blade downwards, facilitating the cutting of the fabric on the conveyor belt by the cutting blade. Due to the limitation of the length of the toothed rack on the conveyor belt, this cutting machine can only cut gauze of a single length, which is quite limiting. Therefore, this utility model proposes a gauze cutting device. Utility Model Content

[0004] The main purpose of this utility model is to provide a gauze cutting device. The connecting plate can be driven by the belt arranged along the length of the frame to move the gripper cylinder freely. This allows the gripper cylinder to drive the clamping plate to clamp the end of the gauze and pull it out to the required length for cutting, thus avoiding the drawback of the prior art which can only cut a single length.

[0008] Preferably, the drive mechanism includes a belt arranged along the length of the frame, the belt being driven by a servo motor, and the other end of the connecting plate being connected to the belt.

[0009] The beneficial effects of this utility model are: the belt set along the length of the frame can drive the connecting plate to move the gripper cylinder freely, so that the gripper cylinder can drive the clamping plate to clamp the end of the gauze and pull out the required length for cutting, thus avoiding the drawback of the prior art that can only cut a single length.

[0010] After cutting, one end of the gauze roll rests on the end of the pallet. The servo motor drives the belt to move, causing the two clamping plates to move closer to the left. The lower clamping plate moves to below the end of the gauze. The gripper cylinder drives the two clamping plates to move closer to each other. The lower clamping plate lifts the end of the gauze upwards to make it horizontal and cooperates with the upper clamping plate to clamp the end, thus facilitating subsequent cutting. No manual supervision is required, continuous cutting can be achieved, and production efficiency can be improved. Attached Figure Description
