[0032] Referring to Figure 1 and the accompanying Figure 2 illustrated, Figure 1 a structure schematic diagram of a temperature-controlled scraper mechanism provided by an embodiment of the present application, Figure 2 is Figure 1 a side view, the temperature-controlled scraper mechanism comprises a base plate 1, a scraper driving mechanism, a scraper assembly, a positioning and mounting assembly 4, and a temperature control assembly.

[0033] A mounting surface is provided on the base plate 1, and the scraper driving mechanism is provided on the mounting surface. The scraper driving mechanism comprises a moving execution mechanism, and the moving execution mechanism is movable relative to the mounting surface. The scraper assembly comprises a blade mounting seat 2 and a blade 3. The blade mounting seat 2 is mounted on the moving execution mechanism, and the blade 3 is mounted on the blade mounting seat 2. The moving execution mechanism can drive the scraper assembly to move relative to the mounting surface, thereby realizing the scraping operation.

The temperature control assembly comprises a temperature adjusting mechanism 5 and a temperature measuring mechanism. The temperature adjusting mechanism 5 is cooperatively mounted on the scraper assembly, and the detection end of the temperature measuring mechanism is attached to the blade 3. Before the scraping operation, the blade 3 of the scraper assembly is heated by the temperature adjusting mechanism 5, and the temperature of the blade 3 is detected in real time by the temperature measuring mechanism. When the temperature of the blade 3 is maintained within the required temperature range of the operation scene, the scraper is driven to operate by the moving execution mechanism. The mechanism can heat the scraper corresponding to the required temperature, so that it can be applied to the use scene with high temperature requirement, and the scraper moving operation is convenient. By controlling the intelligent control of the scraper driving mechanism, the positioning accuracy of the scraper assembly can be improved, and the operability is stronger. Moreover, the installation and removal of each part in the structure are simple, and the maintenance of the machine is convenient.

[0034] In an embodiment of the application, the temperature adjusting mechanism 5 comprises heating pieces attached to both sides of the blade 3 and a temperature control device connected to the heating pieces.

The electromagnet positioning member is mounted on the mobile execution mechanism. The principle of electromagnet locking is based on the basic principle of electromagnet. When current passes through the coil wound on the iron core, a magnetic field is generated around the iron core. This magnetic field will magnetize the iron core, thereby generating an additional magnetic field. The magnetization of the iron core greatly enhances the magnetic field strength of the electromagnet. By controlling the size and direction of the current, the magnetic field strength and polarity of the electromagnet can be adjusted. When locking is needed, the electromagnet is placed close to the object to be fixed, and the ferromagnetic material in the object will be attracted by the magnetic field of the electromagnet, thereby achieving the effect of locking. When unlocking is needed, the current is cut off, and the magnetic field of the electromagnet disappears, and the object is released. It is foreseeable that the above-mentioned locking mode of the electromagnet is only one of the implementation manners, and other implementation manners that can achieve the switching of locking and positioning effects and dismounting effects are also applicable, and will not be expanded herein.

The driving table can drive the screw rod to rotate, thereby enabling the lifting seat 9 to move along the screw rod, and thereby achieving the lifting of the lifting seat 9 along the lifting guide rail 8. Of course, the specific arrangement structure and cooperation mode of the lifting guide rail 8 and the lifting seat 9 are not limited to the above, and any structure that can achieve the above-mentioned lifting cooperation can be applicable, and will not be expanded herein.
