Referring to fig. 1 to 2, the pull roll heat treatment furnace provided by the present disclosure includes a case 2, a transmission device, and a plurality of heat sources, wherein the case 2 has a lower case 21 and an upper case 22, the lower case 21 has an upper end opening, and the upper case 22 is capable of selectively opening and closing the upper end opening to allow the pull roll 1 to be rotatably installed in an inner cavity of the case 2 in an opened state; the transmission device is connected to the traction roller 1 in a transmission way so as to drive the traction roller 1 to rotate; the plurality of heat sources are uniformly distributed in the upper casing 22 and the lower casing 21 to be able to heat the traction roller 1.

When the traction roller 1 is heated, the traction roller 1 is placed in the box 2, and a plurality of heat sources are uniformly arranged in the box 2 to heat the traction roller 1. The casing 2 has a lower casing 21 and an upper casing 22, and the upper casing 22 can close or open an upper end opening of the lower casing 21, and when the upper end opening of the lower casing 21 is opened, the pulling roll 1 can be attached to the lower casing 21 or detached from the lower casing 21. A plurality of heat sources are provided in both the upper casing 22 and the lower casing 21 so as to uniformly and sufficiently heat the traction roller 1, thereby preventing the occurrence of uneven heating. Meanwhile, the traction roller heat treatment furnace is also provided with a transmission device for driving the traction roller 1 to rotate in the box body 2 and uniformly heating the traction roller 1 by matching with a plurality of uniformly placed heat sources. The traction roller 1 is placed in the openable or closed box body 2, heat loss can be prevented when the traction roller 1 is heated, meanwhile, a plurality of heat sources are uniformly arranged in the lower box body 21 and the upper box body 22 and drive the traction roller 1 to rotate by utilizing the transmission device, so that the traction roller 1 can be uniformly heated, and finally the heat treatment level of the heat treatment furnace on the traction roller 1 is effectively improved from the heating degree and the uniformity degree.

In some embodiments, to facilitate the upper case 22 to selectively open and close the upper end opening of the lower case 21, the upper case 22 is mounted to the lower case 21 through a connection shaft 23, and the upper case 22 may be rotated about the connection shaft 23 to thereby open or close the upper end opening of the lower case 21.

Referring to fig. 3, in some embodiments, in order to facilitate the installation of the pull roll 1 into the lower housing 21, the pull roll 1 includes a metal shaft 11 and an asbestos layer 12 surrounding the metal shaft 11, and the heat source sufficiently heats the asbestos layer 12 when the present pull roll heat treatment furnace is in a heated state. The connecting sections of the metal shaft 11 extend out of two ends of the asbestos layer 12 respectively, and two ends of the metal shaft 11 can further extend out of two sides of the box body 2, so that the transmission device can drive two ends or one end of the metal shaft 11 to rotate. Since the asbestos layer 12 is a main functional component of the pull roll 1, the heating of the pull roll 1 is mainly the heating of the asbestos layer 12. When heated, the asbestos layer 12 is entirely inside the tank and is heated.

In some embodiments, to ensure that the pull roll 1 can be mounted to the housing 2 without affecting the closing of the housing 2 and the rotation of the pull roll 1, the housing 2 is provided with a limiting groove. Both ends of the metal shaft 11 can be supported by opposite end walls of the lower case 21, and both end walls and portions of the upper case 22 opposite to the end walls are formed with stopper grooves for defining the supporting positions of the metal shaft 11, respectively. When in installation, the limit grooves respectively arranged on the two end walls of the lower box body 21 are corresponding, and the two ends of the traction roller 1 are respectively clamped into the corresponding pair of limit grooves, so that the box body 2 can be normally closed, and the traction roller 1 is not influenced to rotate under the traction of the transmission device.

In some embodiments, to ensure that the traction roller 1 can rotate at a constant speed, the transmission device includes a gear motor 5 and a transmission chain 6, the gear motor 5 and the transmission chain 6 are disposed on the same side of the box 2, and the transmission chain 6 is sleeved on a power output shaft of the gear motor 5 and a portion of the metal shaft 11 extending out of the box 2. When the gear motor 5 starts to operate, the transmission chain 6 can drive the traction rollers 1 to rotate simultaneously. Generally, the rotation speed of the traction roller 1 is maintained in the speed range of 3-15 rpm by the driving of the gear motor 5.

In some embodiments, to facilitate adjustment of the thermal power of the pull roll heat treatment furnace, the heat source includes heating wires 4 detachably mounted inside the lower case 21 and the upper case 22, and the temperature inside the heating furnace can be changed by adjusting the number and the position of the heating wires 4.

In some embodiments, after the heat treatment of the previous batch of pull rolls 1 is finished, if the box 2 is cooled by adopting a natural cooling mode, a long waiting time is generally required, and in order to reduce the time for which the heat treatment efficiency is submitted, the pull roll heat treatment furnace is provided with cooling pipelines 7 around the outer sides of the lower box 21 and the upper box 22, and the cooling speed is increased by cooling water, so that the treatment efficiency is improved.

In some embodiments, in order to reduce heat dissipation occurring during heating, the pull roll heat treatment furnace is provided with a heat insulating layer 3 made of a refractory material on the inner wall surface of the box 2. Meanwhile, the heat insulation layer 3 can effectively prevent heat in the box body from being transferred outwards because the box body 2 is made of metal, so that the risk of thermal deformation of the box body 2 is reduced, and the heat treatment temperature in the box body is convenient to control.
