[0002] Flat vulcanizing machines are mainly used for vulcanizing flat rubber belts (such as conveyor belts and transmission belts, referred to as flat belts). They have advantages such as high pressure per unit area of ​​hot plate, reliable operation and low maintenance. The main function of flat vulcanizing machines is to provide the pressure and temperature required for vulcanization. The pressure is generated by the hydraulic system through hydraulic cylinders, and the temperature is provided by the heating medium (usually steam).

[0003] Most existing flat vulcanizing machines lack safety protection devices, making them unsafe to use. Due to the large amount of hot steam generated during heating, the extrusion and heating process can easily cause some raw materials to splash outwards, which can easily cause burns when users come into contact with the hot steam. Therefore, a flat vulcanizing machine with safety protection devices is needed to help solve this problem. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This specific embodiment is a flat vulcanizing machine with a safety protection device, such as... Figure 1As shown, the flat vulcanizing machine with safety protection device includes a base 1, a top seat 2 protruding from the top of the base 1, a top plate 4 installed on the top of the top seat 2, protruding plates 5 symmetrically protruding from the top plate 4, and guide rods 3 vertically fixed symmetrically on the protruding plates 5. The bottom of the guide rods 3 is fixed to the top of the top seat 2. A second hydraulic rod 10 is installed inside the top seat 2, and a bottom mold 7 is installed at the extended end of the second hydraulic rod 10. A top mold 6 is installed above the bottom mold 7. In actual operation, the top mold 6 and the bottom mold 7 are equipped with... The device is equipped with a steam heating device, which can be a steam pipe coiled inside the top mold 6 and the bottom mold 7. A first hydraulic rod 9 is installed at the top center of the top plate 4. The extended end of the first hydraulic rod 9 is fixed at the top of the top mold 6. Sleeve rings 8 are symmetrically fixed on both sides of the top mold 6 and the bottom mold 7. The sleeve rings 8 are sleeved on the guide rod 3. By setting the sleeve rings 8, the top mold 6 and the bottom mold 7 can be moved up and down stably during operation, and the sheet-like situation should be avoided as much as possible during movement.

[0026] An extension plate 13 is fixedly attached to one end of the base 1. An operating table 11 is fixed at the top of one end of the extension plate 13. An operating button 12 is installed on the operating table 11. The operating button 12 allows for convenient auxiliary processing of the flat vulcanizing machine during operation.

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a protective assembly 14 for auxiliary processing cavity protection is installed on the outer side of the base 1 and the top seat 2. The protective assembly 14 includes a fixing frame 15, and a protective plate 16 is embedded on the outer side of the fixing frame 15. A lifting cavity is symmetrically opened on the outer side of the base 1. A lifting assembly 17 for adjusting the height of the fixing frame 15 is installed in the lifting cavity. The lifting assembly 17 includes a lead screw 20 that is vertically rotatably installed in the lifting cavity. A protruding plate 151 is provided on the inner side of the fixing frame 15. The protruding plate 151 is sleeved on the lead screw 20. The protruding plate 151 and the lead screw 20 are threadedly engaged. A lifting motor 21 for assisting the rotation of the lead screw 20 is installed inside the base 1. A synchronous pulley 18 is fixed at the bottom of the lead screw 20. The two synchronous pulleys 18 are connected by a synchronous belt 19. The front end of the shaft of the lifting motor 21 is fixed at the bottom of one of the synchronous pulleys 18.

[0028] The lifting motor 21 is activated by the protective component 14. The lifting motor 21 drives the synchronous pulley 18 to rotate, which in turn drives the synchronous belt 19 to rotate. This rotation of the two synchronous pulleys 18 causes the two lead screws 20 to rotate synchronously. The threaded engagement between the protruding plate 151 and the lead screw 20 causes the protruding plate 151 to move upward, thereby raising the fixed frame 15. During the upward movement of the fixed frame 15, the fixed frame 15 and the protective plate 16 are moved to the processing cavity. The fixed frame 15 provides auxiliary protection to the processing position at the top of the top seat 2, effectively blocking steam and extruded plastic during operation, thus minimizing the risk of burns to users who are too close.

[0029] The aforementioned lifting cavity is symmetrically and vertically fixed with limit strips 152, and the protruding plate 151 is symmetrically provided with limit grooves. The limit strips 152 and the limit grooves slide together. By setting the limit strips 152, it can be ensured that the protruding plate 151 can move stably up and down during operation, and misalignment during adjustment can be avoided as much as possible.

[0030] Working principle:

[0031] When vulcanization is required, the mold is placed between the top mold 6 and the bottom mold 7. The lifting motor 21 is started, which drives the synchronous pulley 18 to rotate as a whole. The synchronous pulley 18 drives the synchronous belt 19 to rotate as a whole, thereby causing the two synchronous pulleys 18 to rotate as a whole, which in turn causes the two lead screws 20 to rotate synchronously. The protruding plate 151 is threadedly engaged with the lead screw 20, which causes the protruding plate 151 to move upward, thereby causing the fixed frame 15 to rise as a whole. During the process of the fixed frame 15 rising, it drives the fixed frame 15 and the protective plate 16 to move to the processing cavity, thereby providing auxiliary blocking and protection for the processing position at the top of the top seat 2 through the fixed frame 15.

[0032] During operation, the second hydraulic rod 10 extends and moves the bottom mold 7 to the designated position, while the first hydraulic rod 9 extends the top mold 6, thereby stably pressing the mold into the top mold 6 and the bottom mold 7.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
