Problems solved by technology

[0002] In the actual production process, manpower was mostly used in the opening of bags in the past, which will greatly reduce the efficiency of flour processing. However, because the cost of existing bag opening equipment is too high, we propose to use friction to open bags. The Conceptual Approach of the Bag Machine

Embodiment

[0025] Working principle of the mechanical part

[0026] The conveying speed of the bag on the conveyor belt is 0.5m / s, and the speed of the motor reaches the opening speed of 1m / s. The length of the conveyor belt is 1200mm, and the next pocket is sent every 3s. The torque is: 1370N·m, the speed is 46r / min, and each operation is 120°; the operation is often 0.5s, and the gap is 2.5s. At the position of the opening of the bag, the friction shaft moves in the direction of the bag; because the friction shaft and the bag generate friction, the difference in friction between the bag and the bag produces relative movement. It can be known according to the literature that, taking the woven bag as an example, the friction coefficient of rubber for hemp rope; and the friction coefficient between hemp rope and hemp rope; when the compression of hard rubber is 15%, the rubber unit elastic force produced is: 10.6kg / cm 2 . According to the elastic formula (1) of rubber due to deformatio...

Abstract

The invention relates to a friction type bag opener applicable to various materials and belongs the field of packing and unpacking machines and particularly relates preparation processes of finish product packing. The friction type bag opener comprises a mechanical unit and an electric unit, wherein the mechanical unit comprises a conveying belt, movable friction wheels, a movable rack, a fixed friction wheel and a support rack, and the electric unit is composed of a power source, a PLC (programmable logic controller), a stepping motor driver and a stepping motor; woven bags require bag opening treatment. Due to the fact that the friction coefficient between the rubber of friction parts and plastic bags is larger than that among the plastic bags, the plastic bags can glide and accordingly be opened. The friction type bag opener can achieve automated bag opening operation and replace manual operation, thereby effectively improving the opening efficiency of woven bags and obviously enhancing the automation degree.

Description

technical field [0001] The invention relates to a mechanical structure for opening a packaging bag in a frictional manner, belongs to the field of sealing and unpacking machinery, and in particular relates to the preparation process of finished product packaging. Background technique [0002] In the actual production process, manpower was mostly used in the opening of bags in the past, which will greatly reduce the efficiency of flour processing. However, because the cost of existing bag opening equipment is too high, we propose to use friction to open bags. Conceptual approach of bag machine. [0003] The friction bag opening machine is different from the simple human operation in the past. It uses mechanical body operation, mechanical transmission device, combined with control, electrical and other technologies of mechatronics products, and pursues labor saving, high efficiency, precision, automation and integration. change. Such commodities are not relatively developed ...
