Problems solved by technology

Because there will be a lag time for temperature heating, if it is operated as above, the temperature will definitely exceed the temperature required by the product, which will greatly reduce the yield of the equipment, resulting in time loss, material loss, energy loss, and manpower loss.

Embodiment Construction

[0020] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0021] Such as figure 1 As shown, a temperature controller includes a first temperature control module 1 and a second temperature control module 2, and the first temperature control module 1 and the second temperature control module 2 are respectively connected to an external AC power supply; The temperature control module 1 is used for automatic disconnection after heating to the set temperature; the second temperature control module 2 is used for periodically collecting the heating control signal output by itself after heating to the set temperature, and according to the current cycle The collected heating control signal regulates the heating temperature of the next cycle until the heating temperature is stable; f...

Abstract

The invention relates to a temperature controller comprising a first temperature control module and a second temperature control module. The first temperature control module and the second temperature control module are respectively connected with an external AC power supply. The first temperature control module is used for heating to set temperature and then automatically disconnects. The second temperature control module is used for heating to set temperature and then periodically acquiring heating control signals outputted by the second temperature control module and regulating and controlling heating temperature of the next period according to the heating control signals acquired in the current period until heating temperature is stable. Compared with controllers in the prior art, heating temperature can increase to target temperature through heating and remain stable so that the loss can be effectively reduced, the processing precision can be enhanced and the yield rate can be enhanced.

Description

technical field [0001] The invention relates to the technical field of temperature control, in particular to a temperature controller on a heat-sealing, hot-cutting, and hot-pressing knife shaft on a diaper and sanitary napkin production device. Background technique [0002] In the sanitary napkin and diaper production equipment, due to product process requirements, it is necessary to accurately heat certain knife shafts to a certain temperature and keep it down to produce qualified products; if it is just a switch, turn it on when it is going to be heated It is obviously not advisable to keep it heated and turn it off after the temperature is reached. Because the temperature heating will have a lag time, if it is operated as above, the temperature will definitely exceed the temperature required by the product, which will greatly reduce the yield of the equipment, resulting in time loss, material loss, energy loss, and manpower loss. So it is necessary to solve this problem...
