[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] This application provides a drum vulcanizing device for homogeneous PVC flooring. Please refer to [reference needed]. Figures 1-5 :include;

[0032] Rectangular box 1, with material outlets on both sides for workpiece 2 to pass through;

[0033] Vulcanizing drum 3, which extrudes and vulcanizes workpiece 2, is installed inside rectangular box 1;

[0034] Heating component 4 heats both the upper and lower surfaces of workpiece 2 simultaneously;

[0035] Separation component 5 includes a serrated plate 51, which presses against the vulcanizing drum 3 and separates the workpiece 2.

[0036] In practical applications, the workpiece 2 can be automatically conveyed to the rectangular box 1 for heating via the external conveyor belt 11. The upper surface of the heating component 4 is electrically heated and the lower surface is steam heated. When the workpiece 2 passes through, it can achieve efficient and comprehensive heating.

[0037] After heating is completed, vulcanization is carried out by the action of vulcanizing drum 3. When workpiece 2 separates from vulcanizing drum 3, the separation component 5 can promote the separation of workpiece 2 from vulcanizing drum 3.

[0038] Finally, workpiece 2 completes vulcanization.

[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The heating component 4 includes an electric heating plate 41 disposed at the upper end of the rectangular box 1.

[0040] In practical applications, the electric heating plate 41 can be controlled to heat the upper surface of the workpiece, thus accurately heating the workpiece 2.

[0041] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The heating component 4 includes a vent 421 on the lower surface of the rectangular box 1. A gas diffuser 422 is installed on the lower surface of the rectangular box 1. The lower end of the gas diffuser 422 is connected to the outside high-temperature gas, and the upper end of the gas diffuser 422 is connected to the vent 421.

[0042] A continuous cavity 423 is formed between workpiece 2 and rectangular box 1.

[0043] In practical applications, the gas diffuser 422 is connected to an external high-pressure gas source. The gas is pumped into the gas diffuser 422 by an external high-pressure pump. The gas diffuser 422 diverts the gas to the vent 421 for discharge, directly heating the workpiece 2. The lower surface of the workpiece 2 can be heated evenly through the continuous cavity 423. The hot gas diffuses upward through both sides of the continuous cavity 423.

[0044] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The serrated plate 51 is installed on the side wall of the rectangular box 1 and presses on the vulcanizing drum 3.

[0045] In practical applications, the workpiece 2 adhering to the vulcanizing drum 3 can be peeled off by the physical action of the serrated plate 51, achieving rapid separation.

[0046] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The separation component 5 includes first bearings 521 on both sides of the rectangular box 1, a connecting shaft 522 is installed on the first bearings 521, a streamlined box 523 is installed on the connecting shaft 522, the streamlined box 523 has an opening on one side, a serrated plate 51 is installed at the opening of the streamlined box, and the streamlined box 523 is connected to the outside by a connecting pipe 524.

[0047] A pressure rod 525 is installed at one end of the connecting shaft 522, and a first compression spring 526 is installed on the outside of the rectangular box 1 along with the pressure rod 525.

[0048] In practical applications, the streamlined box 523 is connected to the high-pressure cold air outside through the connecting pipe 524. The cold air from the outside is blown by the external compressor to the opening on one side of the streamlined box 523. The opening is facing the vulcanizing drum 3, which promotes the cooling of the workpiece 2, solidifies the workpiece, and improves the peeling effect.

[0049] The compression spring 526 presses the pressure rod 525 downwards, and by using the lever principle, the streamlined box 523 and the serrated plate 51 are pressed tightly against the vulcanizing drum 3 through the transmission of the connecting shaft 522.

[0050] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The separation component 5 also includes slide grooves 531 on both sides of the streamlined box 523. A rectangular block 532 is installed on the connecting shaft 522. The rectangular block 532 is slidably connected to the slide groove 531. A second compression spring 533 is provided between the rectangular block 532 and the slide groove 531. The second compression spring 533 drives the streamlined box 523 away from the vulcanizing drum 3. A drive motor 534 is installed on the rectangular box 1. A cam 535 is installed on the rotating end of the drive motor 534. The cam 535 contacts the streamlined box 523.

[0051] In practical applications, the positional relationship between the rectangular block 532 and the slide 531 allows the streamlined box 523 to rotate and move horizontally. The drive motor 534 drives the cam 535 to rotate, and the cam 535 drives the streamlined box 523 to move back and forth in the horizontal direction, so that the serrated plate 51 performs a continuous shoveling action, further improving the efficiency of separating the workpiece 2 from the vulcanizing drum 3. The second compression spring 533 makes the streamlined box 523 stick to the cam 535.

[0052] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The rectangular box 1 has conveyor belts 11 on both sides and a roller 12 on one side of the ventilation hole 421.

[0053] In practical applications, the conveyor belt 11 and rollers 12 facilitate the movement of the workpiece 2.

[0054] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The serrated plate 51 is installed at the upper or lower end of the opening of the streamlined box 523.

[0055] In practical applications, if the serrated plate 51 is located at the upper end of the opening of the streamlined box 523, the airflow discharged from the streamlined box 523 will flow downward at an angle.

[0056] If the serrated plate 51 is located at the lower end of the opening of the streamlined box 523, the airflow discharged from the streamlined box 523 will be horizontal.
