A reciprocating screen slot automatic transmission device

Abstract

The invention discloses a reciprocating screen groove automatic transmission device, which includes a mechanical transmission mechanism and a circuit control mechanism. The mechanical transmission mechanism includes a motor, the output shaft of the motor is sleeved with a connecting flange, and the connecting flange connects the first precision Adjust the upper mounting end of the transmission piece, the lower adjustment end of the first precision adjustment transmission piece is connected to the upper adjustment end of the second precision adjustment transmission piece, and the lower part of the second precision adjustment transmission piece is provided with a through hole, which is flexibly connected with the upper end of the connecting rod , the lower end of the connecting rod is flexibly connected to the screen slot; the circuit control mechanism includes a motor, a frequency converter and a timer. The power end of the frequency converter is connected to the three-phase power supply through the linkage normally open main contact, and the load output terminal of the frequency converter is connected to the power supply of the motor. The power supply end of the timer is used to connect to the power supply, and the control end of the timer is connected to the stop controlled end of the inverter through the timer normally closed contact and the inverter stop normally closed contact in turn.

Description

technical field [0001] The invention relates to the technical field of research and development of sieve grooves for tobacco factories, in particular to a reciprocating automatic transmission device for sieve grooves used in tobacco factories. Background technique [0002] With the continuous development of building an economical and green environment-oriented society, the focus of work in today's society and major enterprises has taken green production as the overall production purpose. At present, the reciprocating motion equipment currently used mainly has the following disadvantages: for example, the vibration trough is currently used as the representative for tobacco screening and feeding, but when in use, the working principle of the vibration trough is to use the eccentricity in the vibrator. The rotation of the block generates centrifugal force, which makes the movable parts such as the screen box and the vibrator perform forced continuous circular or approximate cir...

AI Technical Summary

Problems solved by technology

At present, the reciprocating motion equipment currently used mainly has the following disadvantages: for example, the vibration trough is currently used as the representative for the screening and feeding of shredded tobacco, but the working principle of the vibration trough is to use the eccentricity in the vibrator. The rotation of the block generates centrifugal force, which makes the movable parts such as the screen box and the vibrator perform forced continuous circular or approximate circular motion.

Therefore, the vibrating feeding of the sieve can easily break the shredded tobacco

Unnecessary waste is caused, and the shredded shreds involved in cigarettes will affect the quality of cigarettes

The reciprocating motion equipment currently used mainly has the following disadvantages: 1. For example, the shredded tobacco screening currently uses a vibrating trough as a representative, but the shredded tobacco is easily broken due to the vibration of the vibrating trough during use.

Unnecessary waste will be caused, and the broken leaves will be involved in cigarettes, which will affect the quality of cigarettes
