Continuous heating thermoforming device

Abstract

A continuous heating thermoforming device is suitable for raw materials. The continuous heating thermoforming device includes two feeding units, a heating unit, a heat treatment unit, and a cycle molding unit. The feeding units are arranged at intervals and used to clamp Hold the raw material and can be driven to drive the raw material to move. Each feeding unit has two clamping groups arranged at intervals up and down. The clamping groups of the feeding unit jointly define a material clamping space. The heating unit includes a plurality of temperature raising groups for heating the raw material, the heat treatment unit includes a plurality of temperature control groups whose temperature can be controlled separately for heat treatment of the raw material, and the cycle molding unit is set On the side of the material clamping space opposite to the heat treatment unit and used for plastic forming of the raw material, the temperature drop of the raw material is avoided by the adjacent heating unit and the heat treatment unit, thereby achieving Efficiency to reduce process time and increase throughput.

Description

technical field [0001] The invention relates to a thermoforming device, in particular to a continuous heating type thermoforming device. Background technique [0002] refer to figure 1 , a general existing thermoforming device is suitable for a plurality of sheet-shaped raw materials 6 arranged at intervals along an advancing direction a and moving along the advancing direction a. The existing thermoforming device includes a 6, a heating unit 11 above the raw material 6, a heat treatment unit 12 arranged at a distance from the heating unit 11 along the advancing direction a and located in front of the heating unit 11 and above the raw material 6, and a heat treatment unit 12 along the advancing direction a The mold unit 13 that is arranged on the side of the heat treatment unit 12 opposite to the heating unit 11 and is located above the raw material 6 and is used for plastic molding of the raw material 6 , during operation, each raw material 6 moves to The bottom of the he...

Problems solved by technology

[0003] However, since the raw material 6 is not heated by the heating unit 11 and the heat treatment unit 12 during the process of moving from the bottom of the heating unit 11 to the heat treatment unit 12, the heat will inevitably be lost, so that the The temperature of the raw material 6 is lower than the softening temperature, and the heat treatment unit 12 needs to spend extra time and energy to raise the temperature of the raw material 6 again, resulting in prolongation of the process time and a decrease in output
