Description

Technical Field

[0001] This utility model relates to the field of aluminum strip finishing technology, specifically to a winding aid corner wrapping device applicable to various types of rolls. Background Technology

[0002] In aluminum strip finishing equipment, thicker strips often require belt winding aids for winding. Generally, in the same unit, users have many specifications of production tool sleeves, and the sleeve diameter varies greatly. Traditional belt winding aids are generally designed and manufactured according to a single sleeve specification. If a different sleeve is used, the following situations often occur: (1) The angle α between the lead strip and the tensioned strip after passing through the wrapping device is too small, making it difficult for the material head to bite in and not perfectly fit the sleeve, resulting in loose winding. Some aluminum strips may even bend in the opposite direction, resulting in bulging after winding, which seriously affects production; (2) If the angle α is to be increased, it will cause interference between the wrapping device and the tensioned strip and surrounding equipment, making it unusable. Therefore, we propose a winding aid wrapping device that can be applied to a variety of sleeves. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1: Please refer to Figure 1 This utility model provides a technical solution: a winding corner wrapping device applicable to various types of winding drums, including a frame 1. Several guide rollers 3 and a tension roller 4 are mounted on the frame 1. A winding drum groove is formed on the side surface of the frame 1, and a winding drum 6 is rotatably disposed within the groove. The winding drum 6 is connected to an external drive mechanism. A corner wrapping cylinder 5 is hinged to the lower side surface of the frame 1. A corner wrapping arm 7 is hinged to the movable end of the corner wrapping cylinder 5 and is hinged to the frame 1. On the upper part of the corner arm 7, a movable arm 8 is hinged at the end away from the corner cylinder 5. A guide roller 3 is installed at each end of the movable arm 8. A tensioning strip 11 is sleeved on the drum 6. The head loop strip 12 at the end of the tensioning strip 11 is pressed by the guide roller 3 on the movable arm 8 away from its hinged end. A belt 2 is provided between the guide roller 3 and the tension roller 4. An external drive mechanism drives the drum 6 to rotate, which in turn drives the guide roller 3 and the tension roller 4 to rotate through the belt 2, thereby winding the aluminum strip. After the lead coil of aluminum strip 12 enters between the drum 6 and the frame 1, it is pressed by the guide roller 3, so that the lead coil of strip 12 and the tension strip 11 form an angle. The corner arm 7 can swing under the action of the corner cylinder 5. The movable arm 8 is hinged to the corner arm 7. The position of the movable arm 8 on the corner arm can be adjusted according to the winding needs of different sleeve specifications. The traditional fixed corner arm is designed as a type of corner arm 7 hinged to movable arm 8, which adds a joint and degree of freedom. For drums 6 of different diameters, only the relative position of the movable arm 8 on the corner arm 7 needs to be adjusted to achieve a more ideal corner arm position under different drum conditions. After the lead coil of strip 12 passes through the corner device, the angle α between it and the tension strip 11 can be as large as possible, the material head fits the drum better, and the winding effect is better. It is suitable for winding of various drum specifications, avoiding loose winding, reverse bending, and bulging, and ensuring the normal production of aluminum strip.

[0018] In a preferred embodiment, both the movable arm 8 and the corner arm 7 are provided with pin holes, and a fixing pin 10 is installed in the pin holes. The movable arm 8 and the corner arm 7 are hinged by the fixing pin 10. The guide roller 3 on the movable arm 8, which does not contact the head coil strip 12, is rotatably set outside the fixing pin 10, which makes the winding process more stable.

[0019] In a preferred embodiment, the side surfaces of the movable arm 8 and the corner arm 7 are provided with several adjusting pin holes, and adjusting pins 9 are installed in the adjusting pin holes. When changing the drum during production, the operator only needs to insert and remove the adjusting pins to change their positions to complete the switching of the corner movable arm. The operation is simple, safe and reliable.

[0020] More preferably, the movable arm 8 has at least one adjusting pin hole, and the corner arm 7 has at least three adjusting pin holes. The at least three adjusting pin holes are evenly arranged in a circular array around the axis of the fixed pin 10, so that when the movable arm 8 rotates around the fixed pin 10, the adjusting pin hole on the movable arm 8 can be aligned with any adjusting pin hole on the corner arm 7.

[0021] In a preferred embodiment, a sliding groove is provided on the side surface of the frame 1, and a tension roller fixing shaft 13 is slidably arranged in the sliding groove. The tension roller 4 is rotatably arranged on the tension roller fixing shaft 13. The tension roller fixing shaft 13 can slide in the sliding groove and thus drive the tension roller 4 to adjust its position, thereby adjusting the belt 2 according to different drums 6. This is suitable for winding drums of various specifications.

[0022] Example 2: Please refer to Figure 2 The present invention also provides a technical solution that is largely the same as that in Embodiment 1, except that: an electric push rod 17 is installed on the side surface of the frame 1, and the movable end of the electric push rod 17 is fixedly connected to the tension roller fixed shaft 13. The electric push rod 17 pushes the tension roller fixed shaft 13 to move in the slide groove, thereby driving the tension roller 4 to adjust. The adjustment is convenient and the operation is simple.

[0023] The electric push rod 17, the corner cylinder 5, etc. used in this application are all commonly used electronic components in the prior art. Their specific structure, working principle, control method and circuit connection are all well-known technologies and will not be described in detail here.

[0024] Example 3: Please refer to Figure 3This utility model also provides another technical solution, which is largely the same as Embodiment 2, except that: a telescopic rod is installed on the side surface of the frame 1. The telescopic rod includes a fixed cylinder 14 fixedly installed on the frame 1 and a sliding rod 15 slidably installed inside the fixed cylinder 14. The sliding rod 15 is connected to a spring 16 inside the fixed cylinder 14, and the end of the sliding rod 15 is fixedly connected to the tension roller fixed shaft 13. The spring 16 pushes the sliding rod 15, which in turn pushes the tension roller fixed shaft 13, so that it can adapt to different drums 6 to tension the belts 2.
