Description

Technical Field

[0001] The utility model relates to the technical field of feeding, in particular to a feeding device for a shearing machine for producing cold-rolled strip steel. Background Art

[0002] The main purpose of using a feeding device in a shearing machine for cold-rolled strip production is to ensure accurate and stable material feeding, thereby improving the efficiency of the shearing process and product quality. The feeding device effectively controls the material's entry path, reducing the risk of material deviation during feeding, ensuring accurate positioning of the material during shearing, and reducing the probability of unqualified shearing. At the same time, the feeding device can simplify the operating process, improve production efficiency, and provide better convenience and safety for operators. In short, the feeding device is a key device connecting the material conveyor and the shearing machine, playing an important role in optimizing material transportation, improving production efficiency, and ensuring product quality.

[0003] Most existing feeding devices fail to effectively prevent material displacement during the feeding process. For example, as material enters a shearing machine via a conveyor belt or slide, it can shift sideways due to external vibration, friction, or changes in its own weight. This shift not only causes the shearing tools to apply uneven pressure to the material, thereby affecting shearing precision and quality, but can also lead to increased wear on the tools, increasing the frequency of equipment maintenance and replacement. Therefore, a feeding device for shearing machines used in cold-rolled strip production is proposed to address this issue. Utility Model Content

[0014] 1. In the present invention, the second motor starts to rotate and generates a rotating force. The second transmission gear transmits the rotating force generated by the second motor to the connecting gear. The connecting gear transmits the rotating force to the transmission shaft through the connecting rod, and the transmission shaft starts to rotate.

The second transmission gear 10 is fixedly connected to the driving end of the drive assembly. The external rotation of the housing 1 is connected to a connecting rod 9. The connecting rod 9 is used to connect the gear 8 and the transmission shaft 12. The rotational force is transmitted from the connecting gear 8 to the transmission shaft 12. The right side of the connecting rod is fixedly connected to the connecting gear 8. The connecting gear 8 transmits the rotational force to the transmission shaft 12 through the connection with the connecting rod 9.

The left side of the connecting shaft 16 is fixedly connected to the working shaft 13.

[0024] The working shaft 13 is the main working shaft of the equipment, which is responsible for driving the rolling shaft 15, thereby directly generating friction with the material and pushing the material forward. The transmission shaft 12 and the working shaft 13 are externally coupled with a belt 14. The belt 14 is used to connect the transmission shaft 12 and the working shaft 13 to achieve power transmission through friction. The interior of the shell 1 is fixedly connected with two fixed blocks 20. The function of the fixed block 20 is to stabilize and support the load-bearing shaft 19. The top of the two fixed blocks 20 is fixedly connected with the load-bearing shaft 19. The load-bearing shaft 19 is used to support the upper rolling shaft 15 and the force generated by processing. The interior of the shell 1 is slidably connected with two limiting blocks 17, which are used to control other moving parts. The range of motion, the top of the limiting block 17 is fixedly connected to two springs 18, and the spring 18 is used in conjunction with the limiting block 17 to provide a certain restoring force to ensure that the limiting block 17 returns to its initial position after being subjected to an external force. The internal rotation of the limiting block 17 is connected with a connecting shaft 16, and the connecting shaft 16 is used to connect the rolling shaft 15 and the limiting block 17, and has good rotation performance. The outside of the connecting shaft 16 is fixedly connected with the rolling shaft 15, and the upper and lower rolling shafts 15 cooperate with each other to limit the running trajectory of the material and push the material forward. The interior of the shell 1 is fixedly connected with a limiting bar 23, which is used to further control the movement of the components to avoid exceeding the design range.

[0025] Reference Figure 2-Figure 4The bottom of the interior of the shell 1 is fixedly connected to a motor 5. The motor 5 is another power source and is responsible for driving the transmission gears and other components connected to it. The right side of the motor 5 is fixedly connected to a transmission gear 4. The transmission gear 4 is connected to the motor 5 to convert the power of the motor into mechanical motion. The interior of the shell 1 is fixedly connected to a bearing 2. The bearing 2 is used to support the rotating parts, reduce friction loss, and ensure smooth operation. The top of the bearing 2 is fixedly connected to a screw 6. The screw 6 is used to convert rotational motion into linear motion. The smooth thread ensures a smooth feeding process. The outside of the screw 6 is provided with a thread. The inside of the shell 1 is provided with a mounting groove. The screw 6 is rotatably connected in the mounting groove. The outside of the screw 6 is rotatably connected. Working gear 3, working gear 3 is connected to the outside of the lead screw 6, and undertakes the rotational force of the transmission gear 4 by meshing with the transmission gear 4, so that the external rotation of the lead screw 6 is connected to two load-bearing blocks 7, which play a role of support and stability. The right side of the load-bearing block 7 is slidingly connected to a steel rolling push rod 22. The steel rolling push rod 22 is used to replace the steel rolling ring 21 after the processing task, and the steel rolling push rod 22 is retracted inward to the installation position of the steel rolling ring 21. The outside of the steel rolling push rod 22 is slidingly connected to the steel rolling ring 21, and the interior of the shell 1 is fixedly connected to a partition plate 24. The interior of the shell 1 is fixedly connected to two limit bars 23. The limit bar 23 is used to ensure the movement trajectory of the material to avoid collision or exceeding the shearing object so that the sheared item cannot meet the standard.

[0026] Working Principle: First, motor 15 and motor 2 11 provide power to transmission gear 14 and transmission gear 2 10, driving their respective transmission components. The rotation of motor 15 is transmitted to screw 6 via transmission gear 14. The rotation of screw 6 drives the meshing work gear 13 to rotate, thereby converting rotary motion into linear motion. This linear motion causes the load-bearing block 7 to slide, thereby lowering its height to facilitate material loading and driving the rolling push rod 22 to retract inward, freeing up installation space for the rolling ring 21. At the same time, the rotational force of motor 2 11 is transmitted to connecting rod 9 via transmission gear 2 10. Connecting rod 9 transmits the rotational force to drive shaft 12, which in turn transmits the power to work shaft 13 via belt 14. The rotation of work shaft 13 drives the rotation of lower rolling shaft 15, causing the material to be fed forward along the set trajectory under the rolling shaft 15. During this process, limit blocks 17 and springs 18 work together to ensure that the moving parts do not exceed their designed ranges. To ensure smooth operation, bearings 2 support the rotating parts, reducing friction losses and ensuring smooth operation of all components. Simultaneously, limit bars 23 further control the material's trajectory, preventing processing failures due to collisions or exceeding the designed range.
