Description

Technical Field

[0001] The utility model relates to the technical field of hose clamp processing, in particular to an automatic conveying mechanism for stainless steel strips of hose clamps. Background Technique

[0002] According to the working principle of the hose clamp automatic assembly machine, the stainless steel strip is first automatically fed into the inlet of the assembly machine, and then cut, hung with hoop heads, bent, coiled, and wired respectively to complete the hose clamp assembly task. The used stainless steel strip has been stamped with tooth grooves by a punching machine, automatically wound onto an I-beam machine, and then rotated on the I-beam machine to convey the steel strip into the automatic assembly machine. The steel strip unwound from the I-beam wheel is released. Theoretically, it is relatively simple. The feeding fixture of the hose clamp machine can pull the steel strip on the I-beam wheel to unwind, achieving self-feeding and self-using. However, when the I-beam wheel rotates, inertia is generated, causing the steel strip to be fed more, and the surface is easily damaged by friction. If the motor speed is increased, it cannot be synchronized with the assembly machine. Whether it rotates fast or slow is not feasible. After many tests, only by designing an automatic conveying mechanism and an I-beam wheel unwinder, integrated into one, with synchronous feeding and unwinding, can the feeding conditions be met. Content of the Utility Model

[0003] The main purpose of the utility model is to provide an automatic conveying mechanism for stainless steel strips of hose clamps, so as to effectively solve the problems raised in the background technique.

[0004] To achieve the above purpose, the utility model adopts the following technical solution: an automatic conveying mechanism for stainless steel strips of hose clamps, including a feeding device, a steel strip conveying device, and an auxiliary device. The feeding device includes an I-beam wheel, which is installed on a feeding shaft. The feeding shaft is fixed on two cross bars. The two cross bars are rotatably fixed in the middle on a bracket, and the bracket is fixed on a bottom plate. The other ends of the cross bars are connected by a steel pipe, and the steel pipe is fixed on the bottom plate by a screw. The length of the feeding shaft passes through the two cross bars, one end is connected to a hand wheel, and the other end is equipped with a belt pulley, and the belt pulley is connected to the driving belt pulley on the motor shaft by a belt;

[0005] The steel strip conveying device is arranged on one side of the feeding device on the bottom plate, including a feeding frame fixed on the bottom plate. The feeding frame is two columns. The top surface of the feeding frame is fixed with a conveying mechanism floor. Two vertical plates are fixed on the conveying mechanism floor. A driving roller is fixed between the vertical plates by bearings. The driving roller is connected to a servo motor by a coupling. The servo motor is fixed on the feeding frame. A driven roller movable frame is slidably fixed between the vertical plates and above the driving roller, and a driven roller is fixed thereon. The top surfaces of the two vertical plates are fixed with a spring gland by adjusting bolts with a gap. Two pressing bolts are fixed on the spring gland, and springs are sleeved outside the pressing bolts, and the springs are pressed on the driven roller movable frame;

[0006] The auxiliary device includes two roller fixing rods fixed on the column of the unwinding rack and facing the feeding device side, and a support roller is rotatably fixed between the roller fixing rods; a steel strip grounding switch is arranged outside the steel strip conveying device, and another steel strip grounding switch is arranged between the support roller and the steel strip conveying device.

[0007] Preferably, the nut on the adjusting screw can adjust the height of the spool.

[0008] Preferably, adjusting the adjusting bolts on the top surfaces of the two vertical plates can adjust the pressing force between the driving roller and the driven roller.

[0009] Preferably, two guiding columns are fixed on the floor of the conveying mechanism on the side facing the feeding device. The stainless steel strip passes through the support roller from the spool, enters between the two guiding columns, and finally enters between the driving roller and the driven roller of the steel strip conveying device and is pressed for conveying.

[0010] During use, the stainless steel strip is pre-wound on the spool. The stainless steel strip passes through the support roller from the spool, enters between the two guiding columns, and finally enters between the driving roller and the driven roller of the steel strip conveying device and is pressed and conveyed to the assembly machine. A steel strip grounding switch is arranged between the steel strip conveying device and the assembly machine. When the steel strip touches the ground, it will touch the steel strip grounding switch. When the assembly machine pulls the stainless steel strip for feeding, the stainless steel strip stretches and disengages from the steel strip grounding switch, and the steel strip grounding switch gives a start signal. The feeding device and the steel strip conveying device rotate according to the program. The driving roller and the driven roller generate extrusion under the spring pressure to drive the stainless steel strip to move. The two guiding columns limit the movement amplitude of the stainless steel strip, ensure that it enters the steel strip conveying device approximately in a straight line, and finally enters the assembly machine. When a fault occurs, the stainless steel strip loosens and touches another steel strip grounding switch arranged between the support roller and the steel strip conveying device, and the system automatically shuts down to avoid the expansion of the accident. During normal operation, a certain feeding length of the stainless steel strip can be guaranteed.

[0011] The beneficial effects of the utility model: automatic feeding ensures the normal operation of the assembly machine, and it is simple and reliable to use. Description of the Drawings
