The invention relates to the field of thermoplastic forming, in particular to a double-layer heating furnace based on the low-temperature long-distance race principle. The double-layer heating furnace comprises heating rods, heating plates, a feeding belt, a face overturning device and a furnace body. Each heating rod comprises a heating body and walking wheels, wherein a heating unit is arranged in the heating body, and the walking wheels are arranged at the two ends of the heating body. The face overturning device comprises a driving drive plate, a sheave, a cross shaft, a buckle, a spiral rod, a motor and a supporting plate with strip-shaped through holes. The cross shaft penetrates the through holes in the corresponding positions on the two sides. The sheave is fixed to the cross shaft. The driving drive plate is arranged above the sheave. One end of the spiral rod is connected with an output shaft of the motor. The cross shaft is clamped through one end of the buckle, and the other end of the buckle is arranged outside the spiral rod in a sleeving manner. According to the double-layer heating furnace, the low-temperature long-distance race design thought is adopted, the length of the heating plates is increased, plastic plates can be preheated in advance, and the plastic plates can be softened at the low temperature; and the overturning design is adopted for the top heating rods, top heat accumulation is avoided, and the heat utilization efficiency is higher.

The invention provides a near-line disk array library, which comprises all independent driver sets, mechanical arms, a controller and a data management server. All the independent driver sets comprisea plurality of magnetic disk array modules arranged in M rows and N columns. A contact area which extends in the row direction or in the column direction is arranged on one side of all the independent driver sets. The contact area comprises contact points which are in one-to-one correspondence with the M * N magnetic disk array modules, wherein M and N are integers greater than or equal to 2. Each row or each column of contact area corresponds to one mechanical arm. The controller is used for controlling the mechanical arms to move, achieving the connection of the data management server and the disk array modules and then realizing the data transmission. According to the invention, compared with the form of a typical magnetic disk array, the above near-line disk array library is low in cost, high in reliability and good in maintainability. The double-path or multi-path read-write operation can be performed on independent disk drivers. Meanwhile, the data acquisition is convenient, andthe equipment stability is good. The energy consumption is low.

The invention discloses a near-line magnetic disk array library with contact areas at two sides. The near-line magnetic disk array library comprises an all-independent driver set, a plurality of mechanical arms, a controller, and a data management server. The all-independent driver set consists of a plurality of magnetic disk array module groups arranged in M rows and N columns; the front ends andthe rear ends of the plurality of magnetic disk array module groups are arranged externally; first contact areas are arranged at the front ends of the plurality of magnetic disk array module groups;second contact areas are arranged at the rear ends of the plurality of magnetic disk array module groups; contact points are arranged in the first contact areas and the second contact areas; the firstcontact area at each row or each column corresponds to one mechanical arm; and the second contact area at each row or each column corresponds to one mechanical arm. The controller is used for controlling movement of the mechanical arm to a designated position and realizing connection between the data management server and the magnetic disk array module groups to complete data transmission. The near-line magnetic disk array library has advantages of high stability and low energy consumption; reading and writing on the independent disc drivers are carried out simultaneously; and the data are obtained conveniently.
