Automatic roll sealing device for sealing cover of connecting rod type snap-action thermostat

Abstract

The invention discloses an automatic roll sealing device for a sealing cover of a connecting rod type snap-action thermostat. The device comprises an air cylinder, a pressing rod bearing, a pressing rod, a large gear, a bearing, an adjusting spring, a rotating main body shell, a supporting shaft, a spline shaft, limiting blocks, pressing rod sliding blocks, short connecting rods, supporting springs, roller wheel sliding blocks, roller wheels, a contact bearing, a pressure spring, a pressure sliding block, a contact, a motor, a pinion and a long connecting rod. The springs and the contact are used for pressing and positioning, so that the situation that a bimetal disc is clamped does not occur during roll sealing of the sealing cover, and sealing is firmer. Two procedures of pressing the sealing cover and transversely feeding the roller wheels share one set of transmission chain and one piece of driving equipment, so that the layout space is saved, and the overall equipment is more compact and lower in energy consumption. In the roll sealing process of the sealing cover, load balancing is taken into consideration, and the roll sealing is carried out by using the paired roller wheels, so that the roll sealing efficiency and the sealing quality are higher. The device can be used for automatic packaging of the sealing cover of the snap-action thermostat, is more reliable and efficient in packaging, and can be used for large-batch automatic production.

Description

technical field [0001] The invention relates to a jump-type temperature controller, in particular to an automatic rolling sealing device for the cover of a connecting-rod type jump-type temperature controller. Background technique [0002] The sudden jump thermostat is a kind of thermostat, which is a series of automatic control elements that generate conduction or disconnection actions according to the temperature change of the working environment. The function of the sudden jump thermostat is to control the temperature of the appliance within a certain constant temperature range, so it is mainly used in electrical equipment whose circuits need to be automatically turned on and off with temperature changes, such as water dispensers, electric heating water bottles, household appliances, etc. Hot water bags, water heaters, microwave ovens, electric ovens, hair dryers, fireplaces, coating machines, hot-melt machines, laser printers, etc. Its main components include bimetal di...

AI Technical Summary

Problems solved by technology

The sealing machine developed by some small manufacturers independently adopts the sealing method to seal, but the sealing quality is poor. Although the production efficiency is improved, the production yield is greatly reduced.

Since there is currently no manufacturer in the Mainland that can supply automatic roll-sealing aluminum cover equipment for snap-type thermostats, medium and large-scale snap-type thermostat manufacturers have invested a lot of money in the introduction of high-end equipment
