Description

Technical Field

[0001] This utility model belongs to the technical field of tire production equipment, specifically relating to an electromagnetic heating device for a tire die plate. Background Technology

[0002] In tire manufacturing, the tread compound extruder needs to frequently change the die plate and pre-die plate according to different production needs. Before replacement, the die plate and pre-die plate must be preheated to ensure the stability of the extrusion process and product quality. The traditional heating method usually involves placing all types of die plates and pre-die plates into a preheating box, using a resistance infrared heating tube combined with hot air circulation, and heating continuously for 24 hours to reach the required process temperature, allowing them to be used as needed. However, this method has the following problems: 1. Long operating time: The preheating box needs to be heated continuously for 24 hours to meet the production needs of being used as needed, resulting in significant energy waste.

[0003] 2. Limited working method: Because it takes a long time to heat up to reach the process temperature, all types of die plates and pre-die plates need to be loaded into the box and heated repeatedly to achieve the purpose of taking them out as needed. This results in many infrequently used die plates and pre-die plates being heated in the heating box for a long time, causing energy waste.

[0004] 3. Limited heating method: The method of using a resistance infrared heating tube combined with hot air circulation, with air as the heating medium, has low heat conduction efficiency, long heating time, and energy waste.

[0005] 4. High heat loss: The temperature inside the preheating box is usually as high as 120℃. Even if the outer wall of the box is filled with insulation material, a lot of heat will be conducted out, resulting in energy waste. In addition, the heat dissipated into the air will also increase the ambient temperature of the workshop and affect the working environment.

[0006] 5. Limited operation: Because it is necessary to frequently pick up and put the mold plate and pre-molded mold into the heating box, the heating box is large in size. Every time the heating box door is opened, a lot of heat is lost, resulting in energy waste.

[0007] 6. Large equipment size and large footprint: Traditional preheating boxes need to accommodate a large number of die plates and heat them simultaneously, resulting in a large equipment size, occupying a lot of production space, and affecting the flexibility of the production line and the layout of the workshop. Utility Model Content

[0008] This utility model addresses the aforementioned problems by providing a highly efficient, energy-saving, and easy-to-use electromagnetic heating device for mouth-shaped plates.

[0009] To achieve the above-mentioned objectives of this utility model, the present utility model adopts the following technical solution: the present utility model includes a heating box, characterized in that: a door is provided on one side of the heating box, an electromagnetic heating chamber is located inside the door, an electromagnetic heating element is provided inside the box outside the electromagnetic heating chamber, and a temperature measuring mechanism is also provided inside the electromagnetic heating chamber.

[0010] As a preferred embodiment of this utility model, the top of the heating chamber is provided with a workpiece removal auxiliary mechanism. The workpiece removal auxiliary mechanism includes a housing fixedly installed on the top of the heating chamber, a pull rod installed inside the housing via a support bearing, and a handle connected to the pull rod installed on the outside of the housing corresponding to the side of the hatch. A movable frame that moves with the pull rod is installed inside the housing, and a push rod is installed on the movable frame. The end of the push rod extends into the electromagnetic heating chamber from the inner wall of the electromagnetic heating chamber.

[0011] As another preferred embodiment of this utility model, the temperature measuring mechanism includes a bracket disposed inside the chamber, a connecting rod disposed on the bracket, a temperature sensor disposed at the end of the connecting rod, and the end of the connecting rod with the temperature sensor passing through the chamber wall of the electromagnetic heating chamber and disposed inside the electromagnetic heating chamber.

[0012] Furthermore, a buffer spring is provided between the bracket and the connecting rod.

[0013] As a third preferred embodiment of this utility model, the lower end of the hatch is connected to the heating box via a hinge, and the heating box is provided with a locking mechanism that cooperates with the upper end of the hatch.

[0014] As a fourth preferred embodiment of this utility model, the heating box is equipped with an exhaust fan, which is connected to the interior of the heating box and the exterior of the electromagnetic heating chamber.

[0015] As a fifth preferred embodiment of this utility model, the electromagnetic heating chamber, the door, the workpiece removal auxiliary mechanism, and the temperature measuring mechanism are all configured in pairs, for simultaneously heating the die plate and the pre-die plate.

[0016] As a sixth preferred embodiment of this utility model, an electrical control cabinet is provided below the heating box, and a controller connected to the electromagnetic heating element and temperature sensor is provided above the heating box.

[0017] The beneficial effects of this utility model are as follows: 1. Due to the structural characteristics of this utility model, the use of electromagnetic heating elements to heat the die plate and pre-die plate is highly efficient. Each heating only takes 2 to 5 minutes to meet the usage requirements, realizing immediate heating and quick availability without the need for long-term power supply, thus achieving energy saving. At the same time, because of its fast heating speed, only one die plate and / or pre-die plate can be heated at a time. The electromagnetic heating chamber can be set to match the size of the die plate or pre-die plate, which greatly reduces the size of this utility model.

[0018] 2. Energy-saving and efficient: Electromagnetic induction heating acts directly on the die plate or pre-die plate body, causing it to generate eddy current effect for self-heating, avoiding heat loss during hot air conduction, greatly improving energy utilization and reducing overall energy consumption.

[0019] 3. Precise temperature control: The temperature of the die plate is directly measured by a temperature sensor and can be adjusted in a closed loop by a controller to ensure uniform heating of the die plate and meet process requirements.

[0020] 4. Easy to operate and safe and reliable: It is equipped with a workpiece removal auxiliary mechanism, which makes it easy to remove the heated workpiece. It is convenient to use and safe and reliable.

[0021] 5. Durable equipment and low maintenance costs: The electromagnetic induction heating system has no vulnerable parts, has a long service life, reduces the need for replacement and maintenance of traditional heating elements, improves equipment stability, and reduces long-term operating costs.

[0022] This invention significantly improves the preheating efficiency of the die plate by optimizing the heating method, while reducing energy consumption and heat loss, providing the tire manufacturing industry with a more intelligent, efficient, and energy-saving heating solution.

Detailed Implementation

[0027] This utility model includes a heating box 1, which heats only one pre-formed plate and one blanking plate at a time. It adopts electromagnetic induction heating, and it only takes 2-5 minutes to heat to the process temperature in a single cycle. The heating speed is fast, and it can be heated immediately when needed, saving energy. The electromagnetic induction heating method acts directly on the workpiece itself, without indirect heat conduction, resulting in high heating efficiency and low heat loss; the equipment is small in size and occupies little space.

[0028] The heating box 1 has a door 6 on one side, and the door 6 leads to an electromagnetic heating chamber 12. An electromagnetic heating element 13 is installed inside the box outside the electromagnetic heating chamber 12, and a temperature measuring mechanism 11 is also installed inside the electromagnetic heating chamber 12.

[0029] The top of the heating chamber 1 is provided with a workpiece removal auxiliary mechanism 2. The workpiece removal auxiliary mechanism 2 includes a housing 8 fixedly installed on the top of the heating chamber 1. A pull rod is installed inside the housing 8 through a support bearing. A handle 4 connected to the pull rod is installed on the outside of the housing 8 on the side corresponding to the door 6. A movable frame 9 that moves with the pull rod is installed inside the housing 8. A push rod 14 is installed on the movable frame 9. The end of the push rod 14 extends into the electromagnetic heating chamber 12 from the inner wall of the electromagnetic heating chamber 12.

[0030] By setting up the workpiece removal auxiliary mechanism 2, the removal operation of the heated die plate and pre-die plate is simplified, avoiding direct manual contact with the high-temperature workpiece and improving the safety and convenience of operation.

[0031] The temperature measuring mechanism 11 includes a bracket installed inside the chamber, a connecting rod 15 installed on the bracket, a temperature sensor 17 installed at the end of the connecting rod 15, and the end of the connecting rod 15 with the temperature sensor 17 passing through the chamber wall of the electromagnetic heating chamber 12 and installed inside the electromagnetic heating chamber 12.

[0032] Two push rods 14 are arranged horizontally and parallel on the movable frame 9, and the connecting rod 15 of the temperature measuring mechanism 11 is arranged between the two push rods 14.

[0033] A buffer spring 16 is provided between the bracket and the connecting rod 15.

[0034] By setting a buffer spring 16 between the bracket and the connecting rod 15, the impact of the workpiece on the temperature measuring mechanism 11 can be effectively reduced, thus avoiding damage.

[0035] The lower end of the hatch 6 is connected to the heating box 1 by a hinge, and the heating box 1 is provided with a locking device 5 that cooperates with the upper end of the hatch 6.

[0036] The use of hinges and locking mechanism 5 makes the opening and closing of the hatch 6 more stable, preventing the hatch 6 from becoming loose or not sealing properly due to high temperature environment, ensuring uniform temperature inside the heating chamber and improving heating efficiency.

[0037] The heating box 1 is equipped with an exhaust fan 10, which is connected to the interior of the heating box 1 and the exterior of the electromagnetic heating chamber 12.

[0038] By setting up an exhaust fan 10, air can circulate between the external space of the heating chamber and the internal space of the heating box 1, which helps to dissipate heat, prevents the electrical control components from overheating, and improves the stability and service life of the equipment.

[0039] The electromagnetic heating chamber 12, the door 6, the workpiece removal auxiliary mechanism 2, and the temperature measuring mechanism 11 are all configured in pairs, which are used to heat the die plate and the pre-die plate simultaneously.

[0040] The dual heating chamber design allows for simultaneous heating of the die plate and pre-die plate, improving production efficiency, reducing waiting time, and optimizing production rhythm.

[0041] An electrical control cabinet 7 is installed below the heating box 1, and a controller 3 connected to the electromagnetic heating element 13 and the temperature sensor 17 is installed above the heating box 1.

[0042] By independently setting the electrical control cabinet 7 below the heating box 1, the control system of the electromagnetic heating element 13 and the temperature sensor 17 is more centralized, which facilitates maintenance and avoids the electrical control part from being affected by high temperature, thereby improving the stability and safety of the equipment.

[0043] In use, the pre-made die plate and the pre-made die plate are placed into different electromagnetic heating chambers 12, the chamber door 6 is closed and locked by the latch 5, and the electromagnetic heating element 13 is started by the controller 3 to heat the workpieces in the two electromagnetic heating chambers 12 respectively; the temperature sensor 17 detects the data and the controller 3 controls the power of the electromagnetic heating element 13 to achieve precise heating.

[0044] After heating is complete, open the hatch 6, pull the handle 4 of the auxiliary mechanism 2 to remove the workpiece, the handle 4 drives the pull rod to move, the pull rod then drives the moving frame 9 to move, the push rod 14 on the moving frame 9 extends into the electromagnetic heating chamber 12, pushes out the workpiece, and completes one heating operation of the die plate and pre-die plate.
