Abstract
Description
Technical Field
[0001] The present application relates to the technical field of tire vulcanization, and in particular to a vulcanization electromechanical heating hot plate. Background Art
[0002] Tire vulcanization is a critical step in the tire manufacturing process. This process requires a vulcanizer to heat and pressurize the tire embryo, prompting a vulcanization reaction and ultimately shaping the finished tire. Existing vulcanization heating is divided into two parts: internal heating and external heating. The external heating device typically consists of an upper hot plate, a mold sleeve, and a lower hot plate. Heating is achieved by continuously and uninterruptedly passing high-temperature steam into the hot plate as the power source. The high-temperature steam enters through the steam inlet, passes through the zigzag steam channel within the hot plate, and is finally discharged through the steam outlet.
[0003] The utility model with application number 2022205818878 discloses a uniformly heated hot plate of a tire shaping and vulcanizing machine, including a hot plate panel and a hot plate bottom plate. An inner flange and an outer flange are arranged between the hot plate panel and the hot plate bottom plate. The hot plate panel, the hot plate bottom plate, the inner flange and the outer flange together form a heating channel. A steam inlet and a steam outlet connected to the heating channel are arranged on the outer flange. Radial partition plates and radial connecting plates and a hot plate mounting platform extending radially are arranged in the heating channel. The radial partition plates and radial connecting plates are alternately distributed with the hot plate mounting platform and divide the heating channel into several heating chambers. The steam flow channels in the heating chambers are set with equal width and height, and the temperature uniformity is better, which is conducive to shortening the time of tire shaping and vulcanization, improving the quality of tire vulcanization, and reducing energy consumption.
[0004] However, the above-mentioned utility model adopts a high-temperature steam heating method, which mainly has two problems. On the one hand, the high-temperature steam continuously radiates heat from the steam inlet through the steam channel to the steam outlet, and the temperature drops inevitably. In addition, the steam channel extends for a long time in the hot plate, which reduces the uniformity of the hot plate temperature to a certain extent and affects the tire vulcanization quality. On the other hand, the discharged condensed water contains a large amount of heat, which makes it impossible to fully utilize the heat carried by the vulcanization high-temperature steam, resulting in low energy utilization and high energy consumption.

[0028] Depend on Figures 1-4 As shown, the utility model provides a vulcanizing machine electric heating hot plate, which is provided with a hot plate bottom plate, and the hot plate bottom plate is provided with a hot plate upper bottom plate 1 and a hot plate lower bottom plate 2 connected to each other; the hot plate lower bottom plate 2 is annular, and is provided with a plurality of first electric heating element mounting grooves 3 on the hot plate lower bottom plate 2, and the first electric heating element mounting grooves 3 are distributed in a ring shape with the inner ring hole 4 of the hot plate lower bottom plate 2 as the center, so as to improve the uniformity of the temperature of the heating plate; a first electric heating element 5 is installed in each first electric heating element mounting groove 3; a hot plate bottom plate 1 is installed on each first electric heating element mounting groove 3, and the hot plate bottom plate 1 encloses the first electric heating element 5 in the first electric heating element mounting groove 3.
[0029] Depend on Figure 4-Figure 6As shown, a T-shaped slot 6 is provided between two adjacent first electric heating element mounting slots 3, and the extension direction of the T-shaped slot 6 is directly opposite to the inner ring hole 4 of the lower base plate 2 of the hot plate. A second electric heating element mounting slot 18 is provided in the lower base plate 2 of the hot plate, and a second electric heating element 19 is installed in the second electric heating element mounting slot 18; the second electric heating element mounting slot 18 is spaced apart and directly below the T-shaped slot 6, and the two extend in the same direction.
[0030] Before use, the utility model is electrically connected to the external control cabinet through the first positive circuit 7 and the first negative circuit 8, and the second electric heating element 19 is electrically connected to the external control cabinet through the second positive circuit 20 and the second negative circuit 21; by using an external T-block to fit into the T-slot, the lower mold of the vulcanizer is connected to the electric heating plate through the matching T-block / T-slot 6 to complete the preparation work.

When the utility model is used for tire vulcanization, the first electric heating element 5 and the second electric heating element 19 are used for heating, and the steam and the supporting thermal pipelines in the prior art are no longer needed, thereby improving energy utilization and reducing production costs.

After receiving the induction signal, the intelligent control device 14 sends an instruction to the first current controller 10 through the control circuit. After receiving the instruction, the first current controller 10 reduces the current, thereby achieving the purpose of lowering the temperature in the first electric heating element installation groove 3; when the temperature in the first electric heating element installation groove 3 is lower than the preset minimum temperature, the first temperature sensor 9 generates an induction signal and transmits the induction signal to the intelligent control device 14 through the control circuit.

When the difference in the induction temperatures of the two locations exceeds the preset temperature difference, the intelligent control device 14 sends an instruction to the alarm 13 through the control line. After receiving the instruction, the alarm 13 issues an alarm to remind the operator to check and deal with it in time to ensure that the temperature difference between the outer edge and the inner edge of the first electric heating element installation groove 3 is within a controllable range, so that the uniformity of the hot plate temperature is effectively guaranteed.

[0040] In some embodiments, Figure 7 As shown, preferably, the intelligent control system of the present invention further includes a keyboard module 15, a power module 16, a touch screen 17, etc., and the intelligent control device 14 is electrically connected to the keyboard module 15, the power module 16 and other components through a control circuit.

[0041] This utility model is a mechanically heated hot plate for vulcanizing tires, primarily suitable for the production of passenger car tires, light truck tires, and radial truck tires. As is well known, the vulcanization time for passenger car tires is typically 11-13 minutes, for light truck tires 15-37 minutes, and for radial truck tires 45-60 minutes. The above vulcanization times for different tire types are approximate ranges; specific vulcanization times may vary depending on the tire's specifications, materials, design, and production process.
[0042] It can be seen from this that the present invention is particularly suitable for the production of passenger car tires. On the one hand, the vulcanization time of passenger car tires is very short, usually only 11-13 minutes, and the tolerance for temperature fluctuations during vulcanization is smaller, which requires that the temperature fluctuations of the hot plate be stabilized within a smaller range. The temperature fluctuations in the first electric heating element mounting groove 3 and the second electric heating element mounting groove 18 of the lower bottom plate 2 of the hot plate of the present invention are smaller; on the other hand, the specifications of passenger car tires are smaller and no zone heating is required, which requires that the temperature difference between the inner and outer edges of the tire sidewalls during vulcanization is smaller, and the temperature uniformity of the hot plate is higher. The temperature difference between the outer and inner edges of the first electric heating element mounting groove 3 of the lower bottom plate 2 of the hot plate of the present invention is smaller. Therefore, it is very necessary for the present invention to set the above-mentioned intelligent control system to monitor the temperature fluctuations in the first electric heating element mounting groove 3 and the second electric heating element mounting groove 18 of the lower bottom plate 2 of the hot plate of the present invention, as well as the temperature difference between the outer and inner edges of the first electric heating element mounting groove 3.
[0043] It should be noted that the first electric heating element 5 and the second electric heating element 19 can be rare earth thick film circuit heat source chips, or other matching electric heating chips can be selected according to the actual conditions such as the specific specifications, materials, design and production process of the tire.

It should be noted that in the above-mentioned embodiments, the "first", "second", "third" and "fourth" do not represent an absolute distinction in structure and / or function, nor do they represent a sequence of execution, but are merely for the convenience of description.

Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application, such as the lower base plate 2 of the hot plate can be annular or in other shapes; multiple hot plate upper base plates 1 can be installed on each first electric heating element mounting groove 3; the first electric heating element mounting groove 3 can be fan-shaped or in other shapes such as circular, square or other groove-shaped structures; the T-shaped groove 6 can also be a groove-shaped structure of other shapes, etc., should all be included in the scope of protection of the present application.
