At the same time, the hot air flow blown out by the hot air blower passes through the ventilation The air pipe and the second hose enter the air injection pipe and are then injected into the distribution pipe. Hot air is blown toward the top surface of the PVC floor through a plurality of air jet pipes to blow away dust and impurities on the top surface to avoid affecting the vulcanization efficiency. At the same time, the extended end of the air cylinder is controlled to extend from half the length to the longest. At this time, the L-shaped flip rod does not rotate, and the slider is driven to move horizontally through the push plate, and a plurality of air jet pipes move toward the first electric heating plate, so that the hot air flow blown out from the plurality of air jet pipes evenly heats the top surface of the PVC floor.

[0015] The working method of the vulcanization device for PVC floor production specifically comprises the following steps:

[0016] Step 1: Place the PVC floor on the top surface of the first electric heating plate, turn on the hot air blower, the control valve and the first electric heating plate. At this time, the extended end of the hydraulic cylinder is at the shortest, the extended end of the cylinder is at half the length, and the second lever is located in the middle of the L-shaped slide. The bottom surface of the PVC floor is heated and dried through the first electric heating plate. At the same time, the hot air flow blown out by the hot air blower enters the air injection pipe through the ventilation pipe and the second hose, and then is injected into the distribution pipe. Hot air is blown toward the top surface of the PVC floor through a number of jet pipes, so as to blow away the dust and impurities on the top surface and avoid affecting the efficiency of vulcanization; at the same time, the extended end of the control cylinder is extended from half the length to the longest. At this time, the L-shaped flip rod does not rotate, and the slider is driven to move horizontally through the push plate, and a number of jet pipes move toward the direction of the first electric heating plate, so that the hot air flow blown out from the several jet pipes evenly heats the top surface of the PVC floor. In conjunction with the first electric heating plate, the PVC floor is heated and dried evenly on both sides to remove moisture in the PVC floor and prevent moisture from interfering with the vulcanization process of the PVC floor;

[0017] Step 2: After the moisture inside the PVC floor is removed, the extended end of the air cylinder is controlled to shrink and reset to half the length, and then the extended end of the hydraulic cylinder is controlled to extend to the longest, so that the second electric heating plate cooperates with the first electric heating plate to press the PVC floor, and then the second electric heating plate is turned on to perform vulcanization operation on the PVC floor. During the vulcanization process, several electric heating rods are turned on to heat the clean water in the water tank; after the PVC floor is vulcanized, the second electric heating plate and the first electric heating plate are turned off in time, and then the extended end of the hydraulic cylinder is controlled to shrink and reset, so that the lifting platform is reset to its original position. At this time, the top surface height of the lifting platform is the same as the top surface height of the second support seat;

[0018] Step 3: After the lifting platform is reset to its original position, the extended end of the control cylinder is contracted from half its length to the shortest. During this process, the second lever drives the L-shaped flip rod to rotate, so that the U-shaped frame moves toward the first electric heating plate. After the notch of the U-shaped frame cooperates with the input end of the guide groove, the control valve is closed, so that the hot air flow pushes open the one-way valve and is injected into the water tank to increase the air pressure therein, so that the hot water in the water tank is injected into the middle part of the U-shaped frame through the first hose. The hot water entering the middle part of the U-shaped frame will pre-cool the PVC floor after the vulcanization operation to avoid deformation or cracking of the PVC floor due to excessive cooling, thereby ensuring the product quality of the PVC floor; the hot water is then discharged along the U-shaped frame and the guide groove to avoid excessive accumulation of water on the lifting platform.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] When the present invention is in use, the PVC floor is placed on the top surface of the first electric heating plate, and the hot air blower, the control valve and the first electric heating plate are turned on. At this time, the extended end of the hydraulic cylinder is at the shortest, the extended end of the cylinder is at half the length, and the second lever is located in the middle of the L-shaped slide groove. The bottom surface of the PVC floor is heated and dried through the first electric heating plate. At the same time, the hot air flow blown out by the hot air blower enters the air injection pipe through the ventilation pipe and the second hose, and is then injected into the distribution pipe. Hot air is blown toward the top surface of the PVC floor through a plurality of jet pipes, so that dust and impurities on the top surface are blown away to avoid affecting the efficiency of vulcanization. At the same time, the extended end of the control cylinder is extended from half the length to the longest. At this time, the L-shaped flip rod does not rotate, and the slider is driven to move horizontally by the push plate, and the plurality of jet pipes move toward the first electric heating plate, so that the hot air flow blown out from the plurality of jet pipes evenly heats the top surface of the PVC floor. In cooperation with the first electric heating plate, the PVC floor is heated and dried on both sides and evenly, and the moisture in the PVC floor is removed to prevent the moisture from interfering with the vulcanization process of the PVC floor.

[0021] When the present invention is in use, after the lifting platform is reset to its original position, the extended end of the control cylinder is contracted from half the length to the shortest. During this process, the second lever drives the L-shaped flip rod to rotate, so that the U-shaped frame moves toward the first electric heating plate. After the notch of the U-shaped frame cooperates with the input end of the guide groove, the control valve is closed, so that the hot air flow pushes open the one-way valve and is injected into the water tank to increase the air pressure therein, so that the hot water in the water tank is injected into the middle part of the U-shaped frame through the first hose. The hot water entering the middle part of the U-shaped frame will pre-cool the PVC floor after the vulcanization operation, thereby avoiding deformation or cracking of the material of the PVC floor due to excessively rapid cooling of the PVC floor, thereby ensuring the product quality of the PVC floor.

At the same time, the hot air flow blown out by the hot air blower passes through the ventilation pipe (45) and the second hose (102) into the air injection pipe (107), and then is injected into the distribution pipe (106), and passes through a plurality of jet pipes (105 ) blows hot air toward the top surface of the PVC floor, so as to blow away dust and impurities on the top surface; at the same time, the extended end of the control cylinder (411) is extended from half the length to the longest, at this time, the L-shaped flip rod (412) does not rotate, and the slider (101) is driven to move horizontally through the push plate (413), and the plurality of air jets (105) move toward the first electric heating plate (10), so that the hot air flow blown out from the plurality of air jets (105) evenly heats the top surface of the PVC floor, and cooperates with the first electric heating plate (10) to heat and dry the PVC floor on both sides evenly, thereby removing moisture from the PVC floor; Step 2: After the moisture inside the PVC floor is removed, the extended end of the air cylinder (411) is controlled to shrink and reset to half its length, and then the extended end of the hydraulic cylinder (6) is controlled to extend to the longest length, so that the second electric heating plate (12) cooperates with the first electric heating plate (10) to press the PVC floor, and then the second electric heating plate (12) is turned on to perform a vulcanization operation on the PVC floor. During the vulcanization process, a plurality of electric heating rods (44) are turned on to heat the clean water in the water tank (43); after the PVC floor is vulcanized, the second electric heating plate (12) and the first electric heating plate (10) are promptly turned off, and then the extended end of the hydraulic cylinder (6) is controlled to shrink and reset, so that the lifting platform (9) is reset to its original position. At this time, the top surface height of the lifting platform (9) is the same as the top surface height of the second support seat (3); Step 3: After the lifting platform (9) is reset to its original position, the extended end of the control cylinder (411) is retracted from half its length to its shortest. During this process, the second lever (414) drives the L-shaped flip lever (412) to rotate, so that the U-shaped frame (47) moves toward the first electric heating plate (10). After the notch of the U-shaped frame (47) is matched with the input end of the guide groove (8), the control valve (46) is closed, so that the hot air flow pushes open the one-way valve and is injected into the water storage tank (43) to increase the air pressure therein, so that the hot water in the water storage tank (43) is injected into the middle part of the U-shaped frame (47) through the first hose (42). The hot water entering the middle part of the U-shaped frame (47) will pre-cool the PVC floor after the vulcanization operation; the hot water is then discharged along the U-shaped frame (47) and the guide groove (8).
