Description

Technical Field

[0001] This utility model relates to the technical field of steel strip slitting mechanisms, specifically to a packaging steel strip slitting mechanism. Background Technology

[0002] A steel strip slitting mechanism is a common piece of machinery used in the production and processing of steel strips. It is mainly used to slit wide steel strips into multiple narrow strips. It is widely used in the production of steel, aluminum alloys and other metal products, especially in steel mills, metal processing plants, and metal strip production lines. During the production process, steel strips often need to be cut into strips of a certain width according to different uses or specifications. The slitting mechanism is the core equipment to achieve this goal. Traditional slitting methods include manual slitting and mechanized slitting. Among them, mechanized slitting technology has gradually replaced the traditional manual method. Especially in large-scale production, mechanized slitting not only improves production efficiency but also improves cutting accuracy.

[0003] According to a public disclosure of a longitudinal slitting mechanism for stainless steel strip (publication number: CN208392134U), it includes a conveying roller, a pressure roller support, an adjusting pressure roller, and a slitting knife assembly arranged sequentially along the conveying direction of the stainless steel strip. The pressure roller support is arranged perpendicular to the conveying direction of the stainless steel strip. A hinge seat is fixed on the pressure roller support. Both ends of the adjusting pressure roller are connected to hinge arms. The hinge arms are rotatably hinged to the hinge seat via hinge shafts. An adjusting component for adjusting the height of the adjusting pressure roller is connected between the hinge arms and the pressure roller support.

[0004] However, in the above design, the blade will gradually become dull after the steel strip is cut for a long time, which directly affects the cutting quality and needs to be improved. Utility Model Content

[0005] This utility model proposes a packaging steel strip cutting mechanism, which solves the problems mentioned in the above documents.

[0006] The technical solution of this utility model is as follows: A packaging steel strip slitting mechanism includes a machine body, a support plate fixedly connected to the bottom of the machine body, a support frame provided at the top of the machine body, a slitting mechanism provided inside the support frame, a slitting plate fixedly connected to the inner wall of the support frame, a grinding mechanism provided on the circumferential surface of the slitting mechanism, the grinding mechanism including a drive motor, the drive motor being provided on the side of the support frame, a fixed shaft fixedly connected to the end of the output shaft of the drive motor, a grinding disc fixedly connected to the circumferential surface of the fixed shaft, a fixed plate fixedly connected to the inner side wall of the support frame, a connecting rod fixedly connected to the side of the fixed plate, and a contact block fixedly connected to the end of the connecting rod away from the fixed plate.

[0007] The top of the support body is provided with a limiting mechanism, the side of the machine body is fixedly connected to the support body, and the top of the support body is provided with a transmission component. The above design helps to prevent displacement during the cutting of steel strip.

[0008] The grinding disc is in contact with the cutting mechanism. There are two support plates, which are symmetrical about each other along the vertical central axis of the bottom of the machine body. The design of the support plates is beneficial to the stability of the machine body during operation.

[0009] The slitting mechanism is located above the slitting plate, and the above design helps to ensure that the width of the steel strip is consistent after slitting.

[0010] The contact block comes into contact with the slitting mechanism. The contact block is made of rubber, and this rubber material design facilitates the cleaning of impurities adhering to the surface of the slitting mechanism.

[0011] The support frame is equipped with a cooling mechanism. The cooling mechanism includes a water tank fixedly connected to the side of the support frame, a water inlet valve at the top of the water tank, a water pipe running through the side of the water tank, an inclined plate fixedly connected to the inner wall of the support frame, a water outlet groove at the bottom of the inner wall of the inclined plate, and Velcro on the circumference of the water pipe. The above features help prevent the cutting mechanism from overheating during the grinding process.

[0012] A connecting disc is fixedly connected to the circumferential surface of the fixed shaft, and an extrusion block is fixedly connected to the circumferential surface of the connecting disc. A limit plate is fixedly connected to the inner side wall of the support frame. The above design facilitates indirect water discharge.

[0013] The side cross-section of the extrusion block is set to arc shape, and the extrusion block is in contact with the water pipe. The above design is beneficial to generate suction inside the water pipe when the extrusion block extrudes the water pipe.

[0014] The extrusion blocks are arranged in a plurality of units and are arranged in a circumferential array on the circumferential surface of the connecting plate. This design facilitates the extrusion blocks to extrude water pipes.

[0015] The side section of the inclined plate is set to be concave, and the water pipe is located inside the inclined plate. This design is conducive to the overall cooling of the cutting mechanism.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, the driving force of the transmission motor drives the components such as the fixed shaft, grinding disc, fixed plate, connecting rod, and contact block to cooperate with each other, thereby starting the transmission motor set on the side of the support frame, which drives the fixed shaft fixed at the end of the output shaft to rotate. At the same time, it drives the grinding disc fixed on the circumference of the fixed shaft to rotate and grind the slitting mechanism. Subsequently, during the process of slitting the steel strip, the slitting mechanism rotates, and after grinding the slitting tool, the sharpness of the slitting tool is improved, thereby improving the slitting quality.

[0018] 2. In this utility model, the rotation of the fixed shaft drives the connecting plate, water pipe, extrusion block, limiting plate, inclined plate, water outlet groove, Velcro, water tank, water inlet valve and other components to cooperate with each other. When the fixed shaft rotates, it drives the connecting plate fixed on the circumferential surface to rotate. The rotation of the connecting plate drives the extrusion block fixed on the circumferential surface to make a circular motion, thereby extruding the water pipe fixed on the side of the water tank. When the water pipe is extruded, the inside of the water pipe is in a negative pressure state. When the extrusion block stops extruding the water pipe, the inside of the water pipe generates suction force, which prevents the slitting blade from overheating during the grinding process.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-5 As shown, this embodiment proposes a packaging steel strip slitting mechanism, including a machine body 1, a support plate 2 fixedly connected to the bottom of the machine body 1, a support frame 6 provided on the top of the machine body 1, a slitting mechanism 7 provided inside the support frame 6, a slitting plate 10 fixedly connected to the inner wall of the support frame 6, a grinding mechanism 8 provided on the circumferential surface of the slitting mechanism 7, the grinding mechanism 8 including a drive motor 81, the drive motor 81 being provided on the side of the support frame 6, a fixed shaft 82 fixedly connected to the end of the output shaft of the drive motor 81, a grinding disc 83 fixedly connected to the circumferential surface of the fixed shaft 82, a fixed plate 84 fixedly connected to the inner side wall of the support frame 6, a connecting rod 85 fixedly connected to the side of the fixed plate 84, and a contact block 86 fixedly connected to the end of the connecting rod 85 away from the fixed plate 84.

[0029] The top of the support body 3 is provided with a limiting mechanism 4, the side of the machine body 1 is fixedly connected to the support body 3, and the top of the support body 3 is provided with a transmission component 5. The above design helps to prevent displacement during the cutting of steel strip.

[0030] The grinding disc 83 is in contact with the cutting mechanism 7. There are two support plates 2, which are symmetrical about each other along the vertical central axis of the bottom of the machine body 1. The design of the support plates 2 is beneficial to the stability of the machine body 1 during operation.

[0031] The slitting mechanism 7 is located above the slitting plate 10. This design helps to ensure that the width of the steel strip is consistent after slitting.

[0032] In this embodiment, when the slitting mechanism 7 needs to be polished, the operator starts the transmission motor 81 located on the side of the support frame 6, thereby driving the fixed shaft 82 fixed at the end of the output shaft to rotate. At the same time, the polishing disc 83 fixed on the circumferential surface of the fixed shaft 82 rotates to polish the slitting mechanism 7. Subsequently, during the process of slitting the steel strip, the slitting mechanism 7 rotates. At this time, the contact block 86 that contacts the slitting mechanism 7 removes impurities from the circumferential surface of the slitting mechanism 7 to prevent affecting the quality of the steel strip after slitting.

[0033] Example 2

[0034] like Figures 1-5As shown, based on the same concept as Embodiment 1 above, a second embodiment is also proposed. The contact block 86 contacts the cutting mechanism 7. The material of the contact block 86 is rubber. The design of the contact block 86 being made of rubber is conducive to cleaning the impurities attached to the surface of the cutting mechanism 7.

[0035] The support frame 6 is equipped with a cooling mechanism 9. The cooling mechanism 9 includes a water tank 91 fixedly connected to the side of the support frame 6, a water inlet valve 92 on the top of the water tank 91, a water pipe 93 passing through the side of the water tank 91, an inclined plate 97 fixedly connected to the inner wall of the support frame 6, a water outlet groove 98 at the bottom of the inner wall of the inclined plate 97, and Velcro 99 on the circumferential surface of the water pipe 93. The above features help prevent the cutting mechanism 7 from overheating during the grinding process.

[0036] A connecting plate 94 is fixedly connected to the circumferential surface of the fixed shaft 82, and an extrusion block 95 is fixedly connected to the circumferential surface of the connecting plate 94. A limit plate 96 is fixedly connected to the inner side wall of the support frame 6. The above design facilitates indirect water discharge.

[0037] The side cross-section of the extrusion block 95 is set to be arc-shaped, and the extrusion block 95 is in contact with the water pipe 93. The above design is beneficial to generate suction inside the water pipe 93 when the extrusion block 95 extrudes the water pipe 93.

[0038] The extrusion blocks 95 are arranged in a plurality of units and are arranged in a circumferential array on the circumferential surface of the connecting disk 94. This design facilitates the extrusion blocks 95 to extrude the water pipe 93.

[0039] The side section of the inclined plate 97 is set to be concave, and the water pipe 93 is located inside the inclined plate 97. The above design is conducive to the overall cooling of the cutting mechanism 7.

[0040] In this embodiment, when the fixed shaft 82 rotates, it drives the connecting plate 94 fixed on the circumferential surface to rotate. The rotation of the connecting plate 94 drives the extrusion block 95 fixed on the circumferential surface to make a circular motion, thereby extruding the water pipe 93 fixed on the side of the water tank 91. When the water pipe 93 is extruded, the inside of the water pipe 93 is in a negative pressure state. When the extrusion block 95 stops extruding the water pipe 93, a suction force is generated inside the water pipe 93, thereby causing the cooling liquid stored inside the water tank 91 to enter the water pipe 93. As the extrusion block 95 continues to extrude, the cooling liquid enters the interior of the inclined plate 97. At the same time, the cooling liquid falls onto the circumferential surface of the grinding disc 83 and the cutting mechanism 7 through the water groove 98 opened at the bottom of the inner wall of the inclined plate 97.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
