DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a technical solution:

[0024] Embodiment 1:

[0025] A material pressing device of an unwinding machine comprises an unwinding machine 1 and a tensioning and shrinking reel 2. A lifting mechanism for a material pressing roller 7 is arranged on one side of the unwinding machine 1. The material pressing roller 7 is arranged on the upper part of the tensioning and shrinking reel 2. The lifting mechanism is used for the up and down movement of the material pressing roller 7. The material pressing of the steel coil during the conveying process is realized by utilizing the contact between the material pressing roller 7 and the steel coil fixed on the tensioning and shrinking reel 2, thereby improving the unwinding efficiency.

[0026] The lifting mechanism is provided with a telescopic mechanism 10, which limits the position of the steel coil on both sides during the conveying process, ensures that the steel coil will not deviate during the conveying process, and ensures the precise effect of uncoiling.

[0027] The lifting mechanism includes a first mounting seat 3, a connecting rod 4, a rotating rod 5 and a bracket 6. The first mounting seat 3 is arranged on one side of the uncoiler 1, and the upper part of the first mounting seat 3 is rotatably connected to the rotating rod 5 arranged at one end of the connecting rod 4. The other end of the rotating rod 5 is provided with a bracket 6, and the end of the bracket 6 is provided with a pressing roller 7.

[0028] The lifting mechanism further includes a hydraulic rod 8 and a second mounting seat 9 , the base of the hydraulic rod 8 is rotatably connected to the second mounting seat 9 arranged on the uncoiler 1 , and the output end of the hydraulic rod 8 is rotatably connected to the other end of the connecting rod 4 .

[0029] In this embodiment, a lifting mechanism and a pressure roller 7 are provided to achieve pressure treatment of the steel coil during transportation, prevent loosening during unwinding, and improve the unwinding effect and efficiency. The output end of the steel coil is driven by a hydraulic rod 8 to achieve telescopic movement. When the output end of the hydraulic rod 8 is pushed outward, the pressure roller 7 at the end of the bracket 6 descends and contacts the steel coil on the tensioning and retracting drum 2 to achieve pressure treatment. When the output end of the hydraulic rod 8 contracts inward, the bracket 6 and the pressure roller 7 at the end are driven to rise to cooperate with the loading of the steel coil.

[0030] Embodiment 2:

[0031] Based on the first embodiment, the telescopic mechanism 10 mentioned in the first embodiment is described as follows:

[0032] The telescopic mechanism 10 includes a servo motor 101, a first bevel gear 102, a bidirectional screw 103, a second bevel gear 104 and a first slide bar 108. The servo motor 101 is arranged on a motor seat 16 on the bracket 6, and the rotating shaft of the servo motor 101 is fixedly installed with the first bevel gear 102. The first bevel gear 102 is meshedly connected with the second bevel gear 104 arranged at the center of the bidirectional screw 103. The bidirectional screw 103 is connected to the inside of the bracket 6 for rotation, and a first slide bar 108 is arranged on one side of the bidirectional screw 103, and the first slide bar 108 is fixedly installed on the bracket 6.

[0033] The telescopic mechanism 10 also includes a slider 105, a connecting shaft 106 and a side roller 107. The sliders 105 are symmetrically arranged at both ends of the bidirectional screw 103, and one end of the slider 105 is threadedly connected to the bidirectional screw 103, and one end of the slider 105 is slidably connected to the first slide bar 108. The other end of the slider 105 is provided with a connecting shaft 106, and a side roller 107 is rotatably arranged on the connecting shaft 106. The side roller 107 is used to limit the side of the steel coil.

[0034] In this embodiment, a telescopic mechanism 10 is provided to achieve limited conveying of both sides of the steel coil, thereby ensuring precise effects during the unwinding process, avoiding deviation, and improving the unwinding efficiency. The servo motor 101 is used to drive the first bevel gear 102 to rotate. Since the second bevel gear 104 at the center of the bidirectional screw 103 is meshed and connected with the first bevel gear 102, and the bidirectional screw 103 is connected to the internal rotation of the bracket 6, the rotation of the first bevel gear 102 drives the bidirectional screw 103 to rotate. The rotation of the bidirectional screw 103 enables the two sliders 105 at both ends to move toward or away from each other along the first slide bar 108, thereby driving the side rollers 107 on the connecting shaft 106 to move toward or away from each other. Contact limiting is performed on both sides of the steel coil according to its width, thereby ensuring precise effects of steel during the unwinding process, thereby improving the unwinding efficiency.

[0035] Embodiment three:

[0036] Based on the first embodiment, the difference from the first embodiment is that:

[0037] Side plates 14 are provided on both sides of the end of the bracket 6, the interior of the side plate 14 is slidably connected to the second slide bar 13, one end of the second slide bar 13 is fixedly connected to the connecting block 12, a spring 15 is provided between the connecting block 12 and the side plate 14, the spring 15 is sleeved on the second slide bar 13, the connecting block 12 is fixedly installed on both ends of the installation shaft 11, and the installation shaft 11 is rotatably connected to the pressing roller 7.

[0038] In this embodiment, by providing a connecting block 12, a second sliding bar 13, a side plate 14 and a spring 15, a buffering and pressing effect is achieved in the process of pressing the material by the pressing roller 7, and the auxiliary telescopic mechanism 10 limits the two sides of the steel coil, and the second sliding bar 13 on one side of the connecting block 12 at both ends of the mounting shaft 11 is slidably connected inside the side plates 14 on both sides of the end of the bracket 6, so that in the process of driving the pressing roller 7 to descend and press the material by the lifting mechanism, the second sliding bar 13 slides inside the side plate 14 and compresses the spring 15 through the connecting block 12 to achieve the buffering and pressing effect, and in the final pressing of the steel coil, the pressing roller 7 is not driven by the hydraulic rod 8 to move downward to press the material. Through the reset effect of the compressed spring 15, the pressing roller 7 is pressed against the steel coil to automatically press the material, ensuring that the position of the side rollers 107 on both sides of the steel coil remains unchanged, realizing the side limiting function, and preventing the side rollers 107 from contacting the tensioning and retracting reel 2 and affecting its rotation during the downward movement of the pressing roller 7 by the lifting mechanism.

[0039] Working principle: first, the side rollers 107 are located on both sides of the pressing roller 7, so that the pressing roller 7 compresses the spring 15 and presses the surface of the steel coil. The side rollers 107 on both sides limit the two sides of the steel coil, and then the steel coil is loaded onto the tensioning and retracting reel 2 by using the loading trolley, and the pressing roller 7 and the telescopic mechanism 10 are driven downward by the lifting mechanism. The two side rollers 107 are driven to approach each other by the drive of the telescopic mechanism 10, and cooperate with the loading trolley to load the steel coil to the center of the tensioning and retracting reel 2, and the steel coil is fixed by the expansion and contraction of the tensioning and retracting reel 2. After the steel coil is fixed, the pressing roller 7 is driven by the lifting mechanism and the telescopic mechanism 10 to press the surface of the steel. During the pressing process, the pressing roller 7 compresses the spring 15, and the side rollers 107 are located on both sides of the steel coil and contact with the two sides of the steel coil, so as to realize the upper pressing and the limiting of the two sides during the uncoiling and conveying of the steel coil, thereby ensuring the uncoiling efficiency.

[0040] During the process of rotating and unwinding the steel coil, through the operation of the hydraulic rod 8 and the coordination during the rotation of the tensioning and retracting reel 2, as the radius of the steel coil gradually decreases during the transportation of the steel material, the pressing roller 7 and the side rollers 107 are coordinated and descended, contacting the outer side of the steel coil to press the material, and realizing side limiting. As the radius of the steel coil decreases and the bottom end of the side roller 107 approaches the outer side of the tensioning and retracting reel 2, the connecting block 12, the second slide bar 13, the side plate 14 and the spring 15 are utilized to realize that the pressing roller 7 automatically cooperates with the pressure material as the radius of the steel coil decreases, and ensures the positioning of the side roller 107 to prevent the movement of the side roller 107 from contacting the tensioning and retracting reel 2 and affecting the rotation.

[0041] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
