Description

Technical Field

[0001] The utility model relates to the technical field of foil material slitting equipment, in particular to a foil material winding and pressing roller device. Background Art

[0002] The foil winding roller device is a device used in foil slitting equipment. Its function is to apply a certain pressure to the foil when the foil is rolled after the slitting machine cuts the large-width foil into different widths as required, so as to ensure the tightness of the coil during the foil rolling work, reduce looseness and folding, and ensure the quality and stability of the coil.

[0003] To this end, a variety of winding methods have emerged in the prior art. Specifically, a pressure roller is installed on the winding mechanism to improve the winding quality by relying on the weight of the pressure roller. Due to the heavy weight of the pressure roller, the operation is laborious and time-consuming. After rolling, the pressure roller needs to be lifted manually and the foil is taken out, which results in high labor intensity.

[0004] The Chinese utility model patent with announcement number CN 216072318 U records an electrolytic copper foil winding roller device, which drives the end of the roller bracket to move by setting a movable cylinder, thereby realizing the lifting and lowering of the roller, making it easy to wind up or flatten the copper foil at any time, and can realize the adjustment of the copper foil roller in the up and down directions and the front and back directions. When working, the cylinder rod is controlled by operating the switch of the cylinder to move up and down, thereby driving the copper foil roller to move up and down.

[0005] Although the above patent solves the problem in the prior art that the copper foil needs to be manually lifted up the pressure roller and then taken out when winding, which causes high labor intensity; however, the speed of the cylinder when driving the pressure roller up and down is too fast, and the driving pressure roller is lifted and lowered instantly, resulting in a greater safety hazard to the operator.

[0039] like Figure 1-7 As shown, the utility model provides a foil winding and pressing roller 3 device, which includes supporting upright plates 1 arranged vertically on both sides, a horizontally arranged connecting shaft 2 is installed between the upper ends of the two supporting upright plates 1, and a pressing roller 3 is installed on the connecting shaft 2, and a horizontally arranged winding roller 5 is provided between the lower ends of the two supporting upright plates 1 and below the pressing roller 3. The foil winding and pressing roller 3 device also includes a driving mechanism 4 installed on the outer surface of the supporting upright plates 1, the driving mechanism 4 includes a driving cylinder 41, a rack 42, a sliding assembly 44 and a gear 43, the telescopic end of the driving cylinder 41 and the rack 42 are respectively fixed on the slider of the sliding assembly 44, the slide rail of the sliding assembly 44 is fixed on the supporting upright plates 1, and the gear 43 is fixed on the end of the connecting shaft 2 and is meshed and rotatably connected with the rack 42; when the driving cylinder 41 pushes the rack 42 on the slider to move forward and backward relative to the slide rail, the gear 43 drives the connecting shaft 2 to rotate, thereby driving the pressing roller 3 to move up and down.

[0040] The foil winding pressing roller 3 device provided by the utility model drives the rack 42 on the slide block to move forward and backward relative to the slide rail by driving the cylinder 41 to drive the rack 42 to move forward and backward. At the same time, the gear 43 drives the connecting shaft 2 to rotate, thereby driving the pressing roller 3 to move up and down. Under the above structure, the driving cylinder 41 can linearly and slowly drive the pressing roller 3 to move up and down, thereby avoiding the safety hazard to the operator caused by the instantaneous lifting and lowering of the pressing roller 3 when the cylinder directly drives the pressing roller 3 to move.

[0041] Specifically, Figure 1-2 As shown, the support plates 1 on the left and right sides are arranged vertically in parallel, and an axial hole for the two ends of the connecting shaft 2 to pass through is opened at the middle position of the upper end of the support plate 1, and a flange and a bearing are arranged in the axial hole. The two ends of the connecting shaft 2 are respectively penetrated by the axial holes on the support plates 1 on the left and right sides, and the ends of the two ends extend to the outside of the support plate 1, and a gear 43 is installed at both ends of the connecting shaft 2. By setting a keyway on the inner diameter of the axial hole of the gear 43 and the outer diameter of the end of the connecting shaft 2, and installing a key pin in the keyway, the gear 43 is fixed to the end of the connecting shaft 2 to prevent the gear 43 and the connecting shaft 2 from rotating. The connecting shaft 2 is arranged between the support plates 1 on the left and right sides in a horizontal state, and the pressure roller 3 is connected to the connecting shaft 2 through two rocker arms 9, and can swing up and down with the rotation of the connecting shaft 2. When the pressure roller 3 moves downward, it is finally pressed on the winding roller 5. The length of the pressure roller 3 is greater than or equal to the length of the winding roller 5, so as to ensure that the pressure roller 3 fully covers and presses the foil on the winding roller 5.

[0042] In this embodiment, if Figure 3 As shown, the driving cylinder 41, the rack 42 and the sliding assembly 44 are all horizontally arranged below the horizontal line of the gear 43. The bottom of the driving cylinder 41 is fixedly installed on the outer side of the supporting vertical plate 1 through a base. The telescopic end of the driving cylinder 41 is fixedly connected to the slider of the sliding assembly 44 through a fisheye ball head. The slide rail of the sliding assembly 44 is fixed to the outer side of the supporting vertical plate 1 through a screw. The rack 42 is threadedly fixedly connected to the outer side of the upper end of the slider through the screw, and the gear 43 and the rack 42 are meshed and rotatably connected with each other. The slidable stroke between the slider and the slide rail and the length of the rack 42 are both greater than the telescopic stroke of the telescopic rod of the driving cylinder 41. Ensure that the gear 43 and the slider will not derail when the driving cylinder 41 is telescopically moving; when the piston rod of the driving cylinder 41 is telescopically moving, the slider and the rack 42 on the slider are driven to move forward and backward relative to the slide rail, and the rack 42 drives the gear 43 to rotate while the connecting shaft 2 drives the pressing roller 3 to swing up and down; the driving cylinder 41 is connected to the sliding component 44, and a rack 42 is arranged on the sliding component 44 to mesh and rotate with the gear 43 on the connecting shaft 2, so that the driving cylinder 41 will not extend or retract instantly during the telescopic movement, ensuring that the pressing roller 3 can swing up and down linearly and slowly, thereby ensuring the safety of the operator when taking and placing the foil.

When the arc-shaped positioning block 813 is in the groove, the arc-shaped end face of the arc-shaped positioning block 813 is flush with the inner wall of the shaft hole of the positioning ring 81 or lower than the inner wall of the shaft hole of the positioning ring 81; at this time, the positioning assembly 8 can slide and rotate at will on the connecting shaft 2; when the positioning screw 812 is rotated and tightened, the arc-shaped positioning block 813 is pressed tightly against the connecting shaft 2. At this time, the positioning ring 81 is fixed on the connecting shaft 2, and the positioning ring 81 rotates with the rotation of the connecting shaft 2. When the gear bar 811 abuts against the bottom of the rocker arm 9, it continues to rotate.
