Description

Technical Field

[0001] This invention belongs to the field of curtain fabric preparation technology, and relates to an impregnation tank, and more particularly to a graded lifting impregnation device. Background Technology

[0002] Tire cord fabric is a reinforcing material for the tire skeleton, accounting for approximately 10% to 15% of the total tire weight, and has a significant impact on tire performance and lifespan. The cord layers are typically composed of multiple layers of rubber-impregnated cords bonded together with rubber, playing a role in enhancing the overall strength of the tire and stabilizing the tire casing. Tire cord technology is highly sophisticated, requiring stringent standards for fiber strength, elongation, elastic modulus, adhesion to rubber, fatigue resistance, dimensional stability, heat resistance, and impact resistance. Its raw materials include nylon, polyester, viscose filament, para-aramid, and steel wire.

[0003] To improve the adhesion between the tire cord fabric and rubber, the fabric needs to be impregnated with adhesive, and the impregnation machine is the main equipment in the production process. Existing impregnation equipment consists of two parts: a groove installed underground and an impregnation tank installed above the groove. The impregnation tank comprises a tank body, a lifting device, and a liquid inlet. The liquid inlet delivers the adhesive into the tank body, and the lifting device ensures a stable liquid level within the tank, thereby achieving uniform impregnation.

[0004] Traditional impregnation tanks have the following problems: (1) The lifting device in traditional impregnation tanks is a cylinder-type scissor lift platform. Due to the influence of ergonomics, it cannot be directly installed on the ground. The ground needs to be sunken. During daily cleaning and movement, water can easily enter and cause short circuits. Due to the existence of the installation pit, it has the problem of being too large. An installation pit needs to be set at the bottom of the tank so that it can operate during the impregnation process. This not only occupies space but also has a high cost. (2) Since the generator and gravity sensor are placed on the ground, they are easily corroded by wastewater on the ground during the impregnation process, which causes a decrease in the accuracy of the lifting device and thus affects the impregnation effect. (3) Traditional impregnation tanks require a lifting support device to fix the equipment and play a lifting role. The existing impregnation equipment support has the following shortcomings: the parallelism is difficult to adjust. During use, the support surface may tilt, causing the glue to drip. (4) When installing the impregnation equipment, the fault tolerance of the connection end is low. Precise installation is required, and the installation difficulty is high. (5) The structure of traditional lifting impregnation tanks is too complicated and not convenient for daily use and maintenance.

[0005] In view of this, there is an urgent need to design a new dipping tank in order to overcome at least some of the aforementioned defects of existing dipping tanks. Summary of the Invention

[0019] The drive mechanism is connected to the second main gear and can drive the second main gear to rotate, thereby driving each second gear to rotate under the drive of the second chain, and then driving the second screw to rotate.

[0020] Each groove connector is configured based on the second screw, and the groove connector can be raised or lowered accordingly when the second screw rotates.

[0021] In one embodiment of the present invention, the second screw is equipped with a mass sensor.

The second chain 122 connects the second main gear 121 and each second gear 124. The drive mechanism 14 is connected to the second main gear 121 and can drive the second main gear 121 to rotate, thereby driving each second gear 124 to rotate under the drive of the second chain 122, and further driving the second screw 123 to rotate.

[0050] The impregnation tank body 2 has an adhesive groove 25 at its edge, and a support plate 21 and a traveling mechanism 22 are provided at the lower part of the impregnation tank body 2. The support plate 21 has holes 23. The tank body connector 126 is a push pin, which can be set in the corresponding hole 23 to provide support. The traveling mechanism 22 includes several pulleys (e.g., four). The traveling mechanism 22 can be set on the baffle 24. The height of the baffle 24 and the pulleys stacked together is less than the maximum height of the grading lifting platform 1.

[0051] Furthermore, the second screw 123 may be equipped with a mass sensor 128. The secondary lifting assembly 12 may further include a second support device 129, which may be provided with various second fixing mechanisms 125.

[0052] The second support device 129 may include three support frames 1291 and a curved beam 1292; the three support frames 1291 and one curved beam 1292 form the frame of the second support device 129 (generally rectangular in top view). The second support device 129 may further include two motor support frames 1293 and a motor support plate 1294; the two motor support frames 1293 may be arranged based on a support frame 1291 and a curved beam 1292 that are arranged opposite each other, and the motor support plate 1294 is arranged between the two motor support frames 1293; the motor is arranged on the motor support plate 1294.

[0053] The upper gear set may include seven gears, with one gear fixed to each of the four secondary screws, two gears fixed to the secondary support device (for guidance), and one gear fixed to the motor. The lower gear set includes seven gears, with one gear fixed to each of the four primary screws, two gears fixed to the lower secondary support device (for guidance), and one gear fixed to the lower motor. The upper and lower gear sets are respectively engaged and connected to two chains and driven by the motor.

[0054] The primary support device includes four lifting platform supports and four connecting rods. The lifting platform supports are interconnected by the four connecting rods, and the primary screw is installed in the lifting platform supports.

[0055] The secondary support device includes three lifting support frames, one curved beam, two support frames, and a support plate. The support plate is fixed between the two support frames. One end of each support frame is connected to the curved beam, and the other end is connected to the lifting support frame. Both ends of the curved beam are connected to two movable connecting plates. The lifting support frame is connected to the primary screw through the movable connecting plates. The motor is mounted on the support plate.

[0056] In one application scenario of this invention, the graded lifting impregnation tank includes an upper tank body and a lower graded lifting platform. The tank body has an adhesive trough along its edge for replenishing adhesive. A baffle is located at the bottom edge of the tank body, on which four movable pulleys are fixed. The bottom of the tank body has four small holes, which can be of any shape, such as cuboid or dome-shaped, used to connect to the bottom lifting platform to balance the adhesive level. The adhesive trough and the lifting platform are integrated, connected to the adhesive trough. The lifting platform is detachable and can be folded under the adhesive trough. The graded lifting platform includes a double-layered housing, a primary lifting assembly, a secondary lifting assembly, a movable connecting plate, and a drive assembly. The primary lifting assembly, secondary lifting assembly, movable connecting plate, and drive assembly are all located inside the double-layered housing.

[0057] The drive assembly is installed within a double-layered housing and includes a motor, an upper gear set, a lower gear set, and two chains. The upper and lower gear sets are respectively engaged and connected to the two chains, and are driven by the motor. The primary lifting assembly includes four primary screws and a primary support device. The primary support device includes four lifting platform supports and four connecting rods. The four connecting rods are connected to the lifting platform supports by screws, and the four primary screws are installed in the clamps between the four lifting platform supports. The four primary screws are nested with the four gears in the lower gear set, and the four gears move up and down on the primary screws under the control of the motor.

[0058] The secondary lifting assembly includes a gravity sensor, a secondary screw, and a secondary support device. The secondary support device comprises three lifting support frames, a curved beam, two support frames, and a support plate, with the support plate fixed between the two support frames. A motor is mounted on the support plate, with one gear from the upper gear set fixed to the motor and one gear from the lower gear set fixed to the other side. Controlling the movement of the motor gears drives the secondary screw and the upper gear of the primary screw to move up and down, achieving height control. One end of the support frame is connected to the curved beam, and the other end is connected to the lifting support frame. Both ends of the curved beam are connected to two movable connecting plates. One side of the curved beam has two gears from the upper gear set fixed, and the other side has two gears from the lower gear set fixed. The lifting support frame is connected to the primary screw via the movable connecting plates. The secondary screw has a pin at its top, the shape of which matches a small hole at the bottom of the rubber groove. A sleeve is fitted onto the secondary screw, and the gravity sensor is nested on the secondary screw. Because the gravity sensor is nested inside the lifting platform, it is protected and not easily damaged.

[0059] When the glue tank starts operating, the motor is activated. If upward movement is required, each of the upper and lower gear sets has a chain embedded in it. The motor's movement drives the upper and lower gear sets through the motor's upper and lower gears. Both the primary and secondary screws have gears embedded in them, so the secondary screw can be driven upwards by the gears. Since the secondary support device is fixed to the primary screw via a movable connecting plate, the up-and-down movement of the gears on the primary screw can drive the secondary support device upwards. The external double-layered housing is fixed to the primary and secondary lifting components inside the lifting platform. During upward movement, it is unfolded. The four pins fixed on the secondary screw engage with the four small holes at the bottom of the glue tank, pushing the tank upwards. When the tank reaches the predetermined position, the motor in the drive assembly stops, the grading lifting platform maintains a constant height, and the glue enters the tank through the glue trough. As the impregnation process continues, the level of the adhesive in the tank decreases. The gravity sensor in the secondary lifting assembly sends a signal, activating the motor in the drive assembly. This causes the moving connecting plate on the primary screw and the secondary screw on the moving connecting plate to rise simultaneously to the preset height. Because both the primary and secondary screws are threaded, they can be stably fixed at any height during the ascent. This maintains a constant level of adhesive, ensuring thorough impregnation of the fabric.

[0060] When cleaning is required, the motor in the drive assembly drives the upper and lower gear sets to rotate simultaneously. The lower gear set drives the movable connecting plate on the primary screw to descend, and the secondary lifting assembly connected to the movable connecting plate descends. The upper gear set drives the secondary screw in the secondary lifting assembly to descend, and the pin at the top of the secondary screw supports the double-layer housing to descend to its original height. The double-layer housing gradually folds, the height of the tank decreases, and the wheels attached to the tank touch the ground, allowing it to slide out to an easy-to-clean area for cleaning.

[0061] In summary, the graded lifting impregnation device proposed in this invention can improve the convenience of installation, use and cleaning, and effectively save manpower and time costs.

[0062] This invention features a design that enhances stability. Four adjustable feet reduce overall tilting, resulting in better page stability and suitability for surfaces with varying flatness. Compared to traditional cylinder-type lifting platforms, it abandons the unstable cylinder support structure and opts for a simpler and more efficient tabletop support. This tabletop support design significantly improves the overall structural stability, better distributing and bearing the load. Its stable base and optimized shape effectively enhance the stability of the center of gravity, reducing swaying and displacement during use.

[0063] This invention employs a screw-driven lifting system. Compared to traditional scissor lift systems, the screw drive structure is more stable and reliable, enabling precise height positioning.

[0064] During the dipping process, the weight sensor, motor drive and other components in the dipping tank rise together with the lifting platform. A steel shell is set up to protect the motor in the lifting platform. The motor, weight sensor and internal circuit are semi-suspended in the air away from the ground, which can effectively avoid the splashing of wastewater and glue, and solve the problem of wastewater corroding the lifting device and causing instability in the accuracy of the lifting device.
