Arrangement structure of electric heating plate

Abstract

The invention discloses an arrangement structure of an electric heating plate, which comprises a heating plate, and a plurality of rows of first S-shaped grooves are formed in the back surface of theheating plate in an array manner; an S-shaped right-angle wire column heating pipe is mounted in each first S-shaped groove; a cast aluminum gland is fixed on the top surface of each first S-shaped groove through a screw; the cast aluminum gland is provided with a second S-shaped groove opposite to the first S-shaped groove; the S-shaped right-angle wire column heating pipe is clamped in a cavityformed by the first S-shaped groove and the second S-shaped groove; two open grooves are formed in one side of the cast aluminum gland; the two ends of the S-shaped right-angle wire column heating pipe are led out from the open grooves; the arrangement mode of the electric heating plate specifically comprises the following steps that firstly, the heating plate is arranged, and secondly, the cast aluminum gland is arranged; thirdly, the S-shaped right-angle wire column heating pipe is installed; and finally, a temperature control system is arranged. According to the arrangement structure of theelectric heating plate, the manufacturing cost of equipment is reduced, the manufacturing, mounting and overhauling processes are simplified, and the temperature control precision is improved.

[0002] The electric heating plate is mainly used for lamination machine equipment. As the name implies, the lamination machine equipment is a mechanical device that presses multi-layer materials together, and the vacuum laminator is a machine that presses multi-layer materials under vacuum conditions. Equipment; there are two arrangements and structures for the electric heating of the heating plate on the market at this stage: the first is the dot-matrix thick-plate electric heating, which uses a thick iron plate and punches several short dot-matrix-style small holes; For heating, the thickness of the heating plate is about 75, each small yellow block is a heating group, the number of small heating tubes is about 9-16, the disadvantage is that the thickness of the iron plate used is relatively large, the power consumption is large, and the small The number of heating tubes is large, the temperature uniformity is not easy to control, and it is inconvenient to troubleshoot problems, etc., and the insulation and grounding requirements are strict; The thickness of the heating plate is usually 40-50mm thick, the length of the heating tube is usually between 700-900mm, and the layout spacing is about 100mm; the diameter of the heating hole is φ13mm; each heating tube is heated in two sections; the two-section heating tube The power and length are different; the heat dissipation is faster at the edge of the iron plate, and the power of the heating tube is larger; usually each platinum resistor controls 9-12 heating tubes; the control area is 1.5㎡

The temperature control adjustment of the heating plate; each platinum resistor regulates 9-12 heating tubes to heat the iron plate; the disadvantage is that the regulation requires high precision, and the uniformity of temperature is not easy to guarantee. This structure has fatal shortcomings. The heating tube is long and not easy to replace. The side of the heating plate needs to leave a maintenance and replacement space longer than the length of the heating tube + 300. The parts on both sides are completely removed; the processing cost of the heating plate is high, and deep hole drilling is required. The processing period is very long and requires high precision, which increases the production cost of the equipment
