Description

Technical Field

[0001] This utility model relates to the field of tape cutting equipment technology, and in particular to an anti-jamming automatic strapping and cutting machine. Background Technology

[0002] Strapping and cutting machines are widely used in industrial production due to their fast cutting speed, very flat cut surface, and tight strapping.

[0003] Currently, the strapping and cutting machines on the market have the following defects: First, the strapping is not neat; second, the strapping is easy to get stuck in the strapping machine, causing the machine to stop; third, the finished strapping is easy to get stuck in the strapping machine, causing the machine to stop.

[0004] The traditional working process of a strapping and cutting machine is as follows: First, a certain amount of fabric is cut, then the conveyor belt transports it to an automatic strapping machine for strapping. After strapping, the strapped webbing falls into the finished product collection equipment. The first defect is caused by the light weight of individual webbing. Due to vibration and inertia of the conveyor belt, the webbing falls into the strapping machine one after another, resulting in unevenness. The second defect is caused by the softness of the webbing. When the conveyor belt transports the webbing to the strapping machine, some of the webbing gets stuck in the strapping machine, causing the machine to stop. The third defect is caused by the fact that the strapping machine's strapping cutting device is located at the bottom of the strapping machine. After the strapping is cut, a section of the strapping head protrudes. This protruding strapping head is easy to get stuck in the strapping machine, causing the equipment to malfunction and stop.

[0005] Therefore, there is an urgent need for engineers and technicians in this field to develop an anti-jamming automatic strapping and cutting machine that is simple in structure, highly efficient, saves human resources, and has low operating costs. Utility Model Content

The cutting device, strapping device, and transfer device are respectively arranged on the upper part of the frame. The cutting device, strapping device, and transfer device are electrically connected to the intelligent control system. The cutting device includes a cutter seat, a cutting mechanism, and an optical fiber sensor.

The gripper and strap clamp are adjustablely connected to the robotic arm. The robotic arm is slidably connected to a longitudinally arranged guide rail on the upper part of the frame via a slide block. The robotic arm has a folding and telescopic structure.

[0009] In the above structure, the cutting mechanism is correspondingly arranged with the cutter holder. The cutter holder and the cutting mechanism are respectively movably connected to the corresponding cylinders. The cutter holder includes a horizontally arranged rectangular plate-shaped base and a first cylinder. The first cylinder is vertically arranged on a fixed plate inside the frame. The base is detachably connected to the telescopic rod of the first cylinder. The lower part of the cutter holder is integrally provided with guide rods. There are two guide rods, and the two guide rods are respectively movably connected to the corresponding guide holes on the fixed plate.

[0010] In the above structure, the cutting mechanism includes a cutter, a stand, and a second cylinder. The stand is vertically mounted on the frame, and the cutter is correspondingly mounted inside the stand. The cutter is movably connected to the second cylinder, which is vertically mounted in the middle of the stand. The cutter is a tungsten carbide blade with a cutting edge angle of 30°. The surface of the cutter is coated with a diamond-like carbon coating, and the flatness of the cut surface Ra is ≤ 3.2 μm.

[0011] In the above structure, the upper part of the binding device is provided with a U-shaped fixing frame.

The positioning groove is aligned with the blade of the cutter. The two ends of the cable tie are driven by corresponding third and fourth cylinders. The binding pressure of the cable tie is adjustable in the range of 0.5-2.0MPa. The infrared positioning device can monitor the position of the webbing in real time to ensure that the binding alignment accuracy is ≤1mm.

[0012] In the above structure, the gripper is an adaptive gripper, the gripper is equipped with a pressure feedback sensor inside, the gripper is equipped with an anti-slip silicone layer on its surface, the gripper has a friction coefficient ≥0.8, the gripper has an opening and closing range of 20-100mm, and the gripping force of the gripper is adjustable between 5-50N.

[0013] In the above structure, the surface of the conveyor belt is covered with an antistatic nano-coating, which is composed of graphene-polyurethane composite material. The surface resistance of the conveyor belt is ≤10^4Ω. The surface of the conveyor belt is integrated with an ultrasonic cleaning module and a temperature control module.

[0017] The beneficial effects of this utility model are as follows:

[0018] This invention features a binding device installed between the cutting edge of a tape cutter and a conveyor belt, and a tape transfer device located above the conveyor belt. After the tape cutter completes its cutting operation, the binding machine completes the binding operation. The transfer device then picks up the bound tape and transports it onto the conveyor belt, which in turn transports the finished product to a finished product collection device. In this invention, the tape is cut within the binding machine, eliminating the need for a conveyor belt during binding. This prevents the tape from becoming tangled, resulting in neat binding and avoiding confusion during tape transport. It also eliminates the risk of the cable tie getting stuck in the binding machine. After binding, the transfer device transfers the bound bundles onto the conveyor belt, further preventing the cable tie ends from getting stuck. This invention has a simple structure, high efficiency, saves manpower, greatly improves production efficiency, and reduces production costs. Attached Figure Description
