Description

Technical Field

[0001] The utility model relates to the technical field of galvanized sheet processing equipment, and specifically, to a galvanized sheet uncoiling and leveling integrated machine. Background Technique

[0002] With the continuous development of industrial technology and the increasingly fierce market competition, the metal material processing industry has put forward higher requirements for the accuracy, efficiency and automation degree of equipment. As a common metal material, galvanized sheets are widely used in fields such as construction, household appliances, and automobiles. In order to facilitate transportation and storage, the prepared galvanized sheets are generally stored in a reel shape. At this time, when using the reel-shaped galvanized sheets for processing operations, it is usually necessary to perform uncoiling and leveling operations on the reel-shaped galvanized sheets. Uncoiling refers to the process of unfolding the coiled galvanized sheet from the reel to make it into a flat surface; leveling refers to the process of flattening the unfolded galvanized sheet to eliminate its internal stress and surface unevenness, so as to improve the flatness and dimensional accuracy.

[0003] When performing uncoiling and leveling operations, it is generally carried out on a corresponding uncoiling and leveling integrated machine. This type of uncoiling and leveling integrated machine generally uses the rotation of the extrusion rollers to achieve the uncoiling, leveling and conveying operations of the galvanized sheet. However, when this type of uncoiling and leveling integrated machine is in use, it lacks a component that can clamp the end of the galvanized sheet and convey it between the upper and lower extrusion rollers. If a person manually places the end of the galvanized sheet between the upper and lower extrusion rollers for uncoiling, leveling and conveying, during this process, because the extrusion rollers are rotating, it will drive the galvanized sheet to be conveyed forward, and when a person holds the galvanized sheet, it will cause the situation of scratching the hand during the movement of the galvanized sheet, there are certain safety hazards. In view of this, we have proposed a galvanized sheet uncoiling and leveling integrated machine. Content of the Utility Model

A gear 13 is fixedly installed at the end of the rotating shaft 11. The upper and lower gears 13 are meshed with each other. A driving motor 14 is coaxially arranged at the end of the corresponding rotating shaft 11, which is convenient for using the rotation of the pressing rollers 12 to realize the uncoiling and leveling operation of the galvanized sheet;

[0027] Specifically, a slide rail 2 is fixedly installed on the bottom surface of the front end plate of the support frame 1. The slide rail 2 is arranged along the length direction of the support frame 1. A servo motor 21 is fixedly installed at the end of the slide rail 2. A horizontally arranged lead screw 22 is fixedly installed at the end of the output shaft of the servo motor 21. An end conveying component 3 is arranged at the end of the support frame 1. The end conveying component 3 includes a slider 30 slidably connected to the slide rail 2. The lead screw 22 passes through the slider 30 and is slidably connected to the slider 30. An L-shaped plate 31 is fixedly installed on the top surface of the slider 30. A rectangular frame 32 is fixedly installed on the top surface of the L-shaped plate 31. A cylinder 34 is fixedly installed on the top plate of the rectangular frame 32. A U-shaped plate 36 is arranged on the telescopic shaft of the cylinder 34. The opening of the U-shaped plate 36 faces downward. A lower pressing roller 37 is rotatably connected between the left and right side plates of the U-shaped plate 36, so as to clamp the end of the galvanized sheet between the lower pressing roller 37 and the bottom plate of the rectangular frame 32, and then use the servo motor 21 to work to drive the end of the galvanized sheet to be inserted between the upper and lower pressing rollers 12 for conveying.

[0028] In this embodiment, the length of the rectangular frame 32 is less than the distance between the left and right side plates of the support frame 1. The plane where the bottom wall of the rectangular frame 32 is located is at the position between the upper and lower pressing rollers 12, so that the rectangular frame 32 can normally move to the position of the upper and lower pressing rollers 12 near the head for the conveying operation of the galvanized sheet.

[0029] Specifically, an activity gap 311 is arranged between the top plate of the L-shaped plate 31 and the slider 30. The activity gap 311 is used for the sliding-in operation of the bottom plate of the support frame 1, so that the rectangular frame 32 can normally move to the position of the upper and lower pressing rollers 12 near the head.

[0030] Furthermore, a chute 20 arranged along the length direction of the slide rail 2 is arranged in the slide rail 2. The slider 30 is located in the chute 20 and is slidably connected to the chute 20, so that the slider 30 slides more stably.

[0031] In addition, a plurality of support legs 10 arranged in a matrix are fixedly installed on the bottom surface of the support frame 1. The support legs 10 are used for stable support operation.

[0032] It should be noted that a rectangular plate 35 is fixedly installed at the end of the telescopic shaft of the cylinder 34, and a U-shaped plate 36 is fixedly installed on the bottom surface of the rectangular plate 35.

[0033] It should be noted that guide grooves 33 are provided on the inner walls of the left and right sides of the rectangular frame 32, and guide blocks 361 are fixedly installed on the left and right side plates of the U-shaped plate 36. The guide blocks 361 are located in the guide grooves 33 and are slidably connected to the guide grooves 33 to guide the up and down movement of the U-shaped plate 36.

[0034] When the galvanized sheet uncoiling and leveling integrated machine of the present utility model is in use, first, the end of the coiled galvanized sheet is unfolded and placed between the lower pressing roller 37 and the bottom plate of the rectangular frame 32, and at the same time, ensure that the end of the galvanized sheet extends 3 to 5 cm out of the side surface of the rectangular frame 32. Then start the cylinder 34 and make it work. When the cylinder 34 works, its telescopic shaft extends to drive the lower pressing roller 37 to move downward, so as to press the galvanized sheet tightly on the bottom plate of the rectangular frame 32. Then connect the servo motor 21 to an external power source and make it work. When the servo motor 21 works, the output shaft thereof rotates to drive the lead screw 22 to rotate. The lead screw 22 rotates to drive the slider 30 threaded thereon to move. The slider 30 moves to drive the L-shaped plate 31 and the rectangular frame 32 to move, further driving the galvanized sheet to move, so that the end of the galvanized sheet can be inserted between the upper and lower squeezing rollers 12 at the head. After the driving motor 14 is connected to an external power source and drives the squeezing rollers 12 to rotate, the galvanized sheet is conveyed forward, and the plurality of squeezing rollers 12 squeeze the galvanized sheet to realize uncoiling and leveling operations. During the process of conveying the galvanized sheet, the cylinder 34 works, and its telescopic shaft shortens to drive the lower pressing roller 37 to move upward, so that the lower pressing roller 37 no longer excessively clamps the galvanized sheet.
