Abstract
Description
Technical Field
[0001] This utility model relates to the field of galvanized sheet processing technology, and in particular to a galvanized sheet cutting device. Background Technology
[0002] Galvanized steel sheet is made by coating the surface of steel sheet with a layer of metallic zinc to prevent corrosion and extend its service life. This zinc-coated steel sheet is called galvanized sheet. During processing, galvanized sheet is cut using a slitting machine.
[0003] A galvanized sheet processing slitting positioning mechanism, such as the one disclosed in announcement number CN213437545U, includes a load-bearing base plate, a horizontal plate, and a main support column. The main support column is bolted to the top of the load-bearing base plate. A rocker plate is mounted on one end of the main support column via an installation groove. A secondary support column is sleeved on the top of the main support column. A lead screw is mounted inside the secondary support column via a bearing. A support frame is bolted to the top of the secondary support column. A horizontal plate is bolted to the top of the support frame. A vertical column is connected to the top of the horizontal plate via a threaded groove. A grooved wheel is sleeved on the outer side of the vertical column. A grinding block is installed between the vertical columns via an installation groove. This invention allows for height adjustment and can grind the cut edges of the galvanized strip during positioning and fixing, making it suitable for widespread promotion and use.
[0004] The above technical solution has some problems in practical application. When cutting galvanized sheets, the galvanized sheets are prone to shift due to the force applied during cutting. This is especially true when multiple cutting operations are performed on the galvanized sheets at the same time, as the excessive force applied to the galvanized sheets exacerbates the shift. Furthermore, the galvanized sheets do not fully release their own stress during the cutting process, which can also cause shifting during the cutting process. Therefore, it is difficult to guarantee the accuracy of galvanized sheets during continuous cutting.
[0005] Therefore, it is necessary to invent a galvanized sheet cutting device to solve the above problems. Utility Model Content

[0023] Specifically, pressure rollers 11 are movably mounted on both ends of the movable sleeve 9 via bearings, and the bottom end of the pressure roller 11 is on the same plane as the top end of the support roller 5. Locking bolts are installed through the screw holes in the middle of the outer side walls of the positioning sleeve 6 and the movable sleeve 9. The locking bolts are used to lock the positions of the positioning sleeve 6 and the movable sleeve 9, thereby achieving the effect of locking the position of the cutter 10.
[0024] More specifically, a connecting seat 12 is fixedly provided at the bottom of the insert plate 7. A movable arm 13 is movably provided at one end of the connecting seat 12 via a pin. A threaded sleeve 14 is movably provided at the bottom end of the movable arm 13 via a pin. A double-ended screw 15 is provided through the inside of the threaded sleeve 14. The double-ended screw 15 is movably provided at the bottom end of the inner side wall of the fixed frame 2 via a bearing. The double-ended screw 15 cooperates with the threaded sleeve 14, causing the two movable arms 13 to move relative to each other. The movable arms 13 drive the insert plate 7 to move up and down through the connecting seat 12. The insert plate 7 drives the cutter 10 to move up and down through the support shaft 8, so that the cutter 10 is inserted between the two support rollers 5.
[0025] Furthermore, a movable frame 16 is provided in the middle of the upper surface of the base 1. A movable roller 17 is movably provided at the top of the movable frame 16 via a bearing. The movable roller 17 is flush with the support roller 5. When the galvanized sheet passes through the support roller 5 and the movable roller 17, it falls freely in the space between the support roller 5 and the movable roller 17, thus releasing the stress.
[0026] Furthermore, a positioning screw sleeve 18 is fixedly installed at the bottom center of the movable frame 16, and a positioning screw 19 is installed through the inside of the positioning screw sleeve 18. The positioning screw 19 is movably installed above the base 1 via a bearing. Slide grooves 20 are provided at both ends of the lower surface of the movable frame 16.

The slide grooves 20 and the slide rail 21 are used to restrict the movable frame 16 to slide only horizontally. Feeding guide rollers 22 and winding rollers 23 are respectively provided at both ends of the upper surface of the base 1. The feeding guide rollers 22, winding rollers 23 and movable rollers 17 are all located at the same height.
[0027] Working principle of this utility model:
[0028] When this device is in use, the galvanized sheet to be processed is pulled through the feed guide roller 22, the movable roller 17, and the support roller 5 in sequence before reaching the take-up roller 23. By rotating the handwheel at one end of the double-headed screw 15, the double-headed screw 15 engages with the threaded sleeve 14, causing the two movable arms 13 to move relative to each other. The movable arms 13 drive the insert plate 7 to move up and down through the connecting seat 12. The insert plate 7 drives the cutter 10 to move up and down through the support shaft 8, so that the cutter 10 is inserted between the two support rollers 5. At this time, the cutter 10 can cut the galvanized sheet. After the cutter 10 is inserted into the galvanized sheet, the cutter and the two sides of the cut of the galvanized sheet are in close contact, which can ensure that the galvanized sheet does not shift, thereby achieving the limitation of the galvanized sheet.
[0029] When the galvanized sheet passes through the support roller 5 and the movable roller 17, it falls freely in the space between the support roller 5 and the movable roller 17, thus releasing stress. During this process, by rotating the handwheel at one end of the positioning screw 19, the positioning screw 19 cooperates with the positioning sleeve 18, which can adjust the position of the movable frame 16. The movable frame 16 can drive the movable roller 17 to move, thereby adjusting the distance between the support roller 5 and the movable roller 17, and thus achieving the effect of adjusting the falling height of the galvanized sheet. This achieves stress release of the galvanized sheet while avoiding its normal conveying due to excessive falling.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
