Stress, shifting block 4122 is avoided to certain side over-tilting, so as to be stretched in the presence of spring 4123 according to actual conditions
Adjust the length of itself.
The raw pipeline material released through material screening machine structure 41 enters wedge-like opening 12 in order, and the bottom surface of wedge-like opening 12 is provided with more
Steel bar slide rail 121（As shown in Figure 3）, the friction of raw pipeline material and the bottom surface of wedge-like opening 12 is reduced, raw pipeline material is smoothly entered
Enter into temperature adjustment casing 1.
As described in figures 1 and 5, guiding mechanism 13 is provided with the port of export of wedge-like opening 12, including passes through support 133 and temperature adjustment
The arc-like sheet 131 of the port of casing 1 rotation connection, the bolt 132 for being fixed on the port of temperature adjustment casing 1, from the port of export of wedge-like opening 12
The raw pipeline material rolled out is fallen on the arc-like sheet 131 of guiding mechanism 13, and lower end and the transport mechanism of arc-like sheet 131 are in same
Level height, the direction of advance for the raw pipeline material that drops can be adjusted, the transport mechanism for making it fall in temperature adjustment casing 1
On, carry out next step processing, conveying.The port wall of the place support 133 of arc-like sheet 131 and temperature adjustment casing 1 is rotated by latch
Connection, is provided with limited block 1311, staff need to only rotate the guiding in process on the support 133 of arc-like sheet 131
Mechanism 13, make limited block 1311 and be fixed on the grafting of bolt 132 of the port of temperature adjustment casing 1, tighten the nut on bolt 132
1321, it is contradicted with limited block 1311 so as to realize fixation；Nut 1321 can unscrewed during, by arc
Piece 131 and its support 133 are put down, and the adjustment of angle can also be conveniently realized while dismounting.
As shown in Fig. 2 the raw pipeline material come from the rolling of guiding mechanism 13 falls in the transport mechanism in temperature adjustment casing 1, the biography
Send mechanism include respectively with the side wall of temperature adjustment casing 1 rotation connection driving shaft 21 and driven shaft 22, be connected to driving shaft 21 and from
Conveyer belt 23 between moving axis 22, conveyer belt 23 include the equal cross bar 6 in some intervals, and raw pipeline material drops in adjacent crossbars 6
Between, it is possible to achieve firm grips, and is advantageous to the steady of course of conveying, and driving shaft 21, which rotates, drives driven shaft 22 to transport
Dynamic, conveyer belt 23 drives the raw pipeline material on conveyer belt 23 to be moved in temperature adjustment casing 1, carries out temperature adjustment the pre-heat treatment.
Because the temperature in process in temperature adjustment casing 1 is very high, so being enclosed with asbestos layer 61, Neng Gouqi on cross bar 6
Heat-insulated effect, avoid heat on cross bar 6 from excessively concentrating the warm-up operation for influenceing raw pipeline material, ensure that the smooth of working process
Carry out.
