Technical Field

[0001] This utility model belongs to the field of vulcanizing machine technology, specifically relating to a partial vulcanizing machine for rubber products. Background Technology

[0002] A localized vulcanizing machine is a specialized device for locally heating and vulcanizing rubber products. Because rubber components of large rubber products cannot be disassembled and placed into traditional large vulcanizing tanks for overall vulcanization or repair, a localized vulcanizing machine can directly heat and pressurize the specific area requiring vulcanization or repair to complete the vulcanization process. This improves production efficiency and saves production costs.

[0003] Currently common partial vulcanizing machines consist of an enclosed chamber containing a drive mechanism and a heating system, including a heating plate. This structure allows the drive mechanism to move the heating plate to heat the rubber product, enabling localized vulcanization. However, the enclosed structure makes it inconvenient to place and remove rubber products from the chamber, thus affecting production efficiency. Utility Model Content

[0027] In some embodiments of this application, a frame is provided on the first support column 2. The frame includes an upper plate 7, a lower plate 8, and a side plate 9. The upper plate 7 and the lower plate 8 are parallel to each other. One side of the upper plate 7 is connected to the second support column 3, and the other side is connected to the side plate 9. One side of the lower plate 8 is connected to the second support column 3, and the other side is connected to the side plate 9.

[0030] In some embodiments of this application, the electric cylinder 6 includes a cylinder body, a lead screw, a nut, and a piston rod. The cylinder body is fixed to the outer surface of the side plate 9. The lead screw is disposed inside the cylinder body and rotatably connected to the cylinder body. The nut is sleeved on the outside of the lead screw and threadedly engaged with the lead screw. The piston rod is connected to the nut. The lead screw is driven to the motor 4 via a reducer 5. The heater is connected to the end of the piston rod. The motor 4 drives the lead screw to rotate via the reducer 5. When the lead screw rotates, it drives the nut to move along its axial direction, thereby causing the piston rod to extend or retract. With this structure, the motor 4 can drive the lead screw to rotate. When the lead screw rotates, it can drive the piston rod to extend or retract, thereby causing the heater to move toward or away from the rubber product, realizing the heating and vulcanization of the rubber product.

[0031] In some embodiments of this application, the cylinder body is fixed to the side plate 9 by screws.

[0032] In some embodiments of this application, motor 4 is a servo motor. Servo motors are widely used in the field of automation, enabling highly accurate control of speed and position. They convert electrical signals into torque and speed to drive the controlled object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. Compared with a single asynchronous motor, the servo motor has significant advantages such as large starting torque, wide operating range, and no self-rotation. As the power source for the entire vulcanizing machine, motor 4 drives the electric cylinder 6 to reciprocate up and down, providing downward pressure.

[0033] In some embodiments of this application, speed reducers are generally used in low-speed, high-torque transmission equipment. They reduce the speed of a motor, internal combustion engine, or other high-speed power source by meshing a gear with fewer teeth on the input shaft with a larger gear on the output shaft. Ordinary speed reducers may also have several pairs of gears operating on the same principle to achieve the desired speed reduction. The ratio of the number of teeth on the large gear to the number of teeth on the small gear is the transmission ratio. Speed ​​reducers are used to increase downforce and ensure that the torque meets requirements.

[0034] In some embodiments of this application, the electric cylinder 6 directly drives the heater to move, ensuring that the heater and the support platform can press the rubber product that needs to be vulcanized.

[0035] In some embodiments of this application, the rated power of motor 4 is 0.4kw, the driver model is SV630PS2R81, it has a braking function, its model is Huichuan MSIH4-40B30CB-T334R, the rated torque is 1.27Nm, the rated speed is 3000RPM, and the reducer 5 is configured with a ratio of 1:25.

[0036] In some embodiments of this application, after configuring the reducer 5 with the servo motor, the electric cylinder can be driven to perform reciprocating motion. The rated thrust of the electric cylinder is 15KN, the rated stroke is 500mm, and the rated speed is 20mm / s.

[0037] In some embodiments of this application, the heater includes a first heating plate 13 and a connecting assembly 14. The first heating plate 13 is electrically connected to the explosion-proof electrical cabinet 10. The connecting assembly 14 includes a U-shaped member, a connecting shaft, and a rotating shaft. The U-shaped member includes a left plate, a bottom plate, and a right plate connected in sequence. The bottom plate and the heating plate are connected via the connecting shaft. A fisheye connector 15 is connected to the end of the piston rod. The fisheye connector 15 includes a connecting rod and a spherical bearing mounted on the connecting rod. The connecting rod is connected to the end of the piston rod. The rotating shaft passes through the spherical bearing, and its two ends are connected to the left plate and the right plate, respectively. The explosion-proof electrical cabinet 10 supplies power to the first heating plate 13, causing the first heating plate 13 to heat up and heat the rubber product. This structure improves the stability of the connection between the first heating plate 13 and the piston rod. When the piston rod and the connecting assembly 14 are connected via the fisheye connector 15, the first heating plate 13 can move freely in multiple directions relative to the piston rod, allowing the first heating plate 13 to be flexibly adjusted to adapt to different rubber products.

[0038] In some embodiments of this application, a second heating plate 16 is provided on the support platform. The second heating plate 16 is electrically connected to the explosion-proof electrical cabinet 10, and corresponds to the first heating plate 13. The explosion-proof electrical cabinet 10 supplies power to the second heating plate 16, causing the second heating plate 16 to heat up and thus heat the rubber product. Using this structure, the simultaneous heating of the rubber product by the first heating plate 13 and the second heating plate 16 improves the heating efficiency and vulcanization effect of the rubber product.

[0039] In some embodiments of this application, the partial vulcanizing machine further includes a temperature sensor for detecting the temperature of the first heating plate 13 and the second heating plate 16. With this structure, the temperature of the first heating plate 13 and the second heating plate 16 can be detected by the temperature sensor, facilitating precise adjustment of their temperatures.

[0040] In some embodiments of this application, two first support columns 2 are provided, with the bottom ends of both first support columns 2 connected to the base 1 and the top ends of both first support columns 2 connected to the bearing platform. The bottom ends of the first support columns 2 are provided with multiple first support ribs, which are connected to both the first support column 2 and the base 1, and are evenly distributed along the circumference of the first support column 2. This structure, using two first support columns 2 for support, improves the stability of the bearing platform, thereby improving the stability during rubber product processing. The multiple first support ribs further enhance the stability of the first support column 2 during installation.

[0041] In some embodiments of this application, the bottom end of the second support column 3 is provided with a support assembly, which includes an upper ring plate, a lower ring plate, and a second support rib. Both the upper and lower ring plates are fitted around the outer periphery of the second support column 3. The lower ring plate is connected to the base 1. The second support rib is connected to the upper ring plate, the second support column 3, and the lower ring plate simultaneously. Multiple second support ribs are provided, and these ribs are evenly distributed along the circumference of the second support column 3. This structure, using the upper ring plate, the second support ribs, and the lower ring plate to support the second support column 3, improves the stability of the second support column 3 during installation.
