Description

Technical Field

[0001] This utility model relates to the field of unwinding equipment technology, and in particular to a unbundling device. Background Technology

[0002] Steel coils, as a crucial raw material in modern industry, require an uncoiling process before use. Currently, large-scale modern production lines commonly employ fully automated uncoiling equipment, achieving highly efficient assembly line operations. For example, a steel strip unbundling machine with publication number CN103770991A automatically unbundles the steel strips by setting up a frame and installing corresponding shearing mechanisms on the frame. However, for some small and medium-sized manufacturers, repair shops, or flexible processing scenarios, fully automated uncoiling equipment presents challenges such as high purchase costs, large footprint, and insufficient equipment flexibility. Therefore, in these scenarios, production still heavily relies on manual methods for the initial unbundling operation. During manual unbundling, operators typically need to use hand tools such as diagonal pliers, wire cutters, or pneumatic pliers to cut the bundled steel strips at close range. This traditional manual operation method has significant defects and safety risks: First, the elastic potential energy accumulated in the taut steel strip is suddenly released at the moment of cutting, which can easily cause it to break and pose a serious threat to the personal safety of the operator; Second, after the strapping is cut, the unrestrained steel coil head may rebound rapidly under the action of internal stress, which may also cause an impact accident.

[0003] To address the aforementioned risks and improve operational efficiency, some semi-automatic auxiliary tools or methods have emerged in the market. However, these existing technologies still have shortcomings. For example, while some tools achieve remote cutting, they are difficult to quickly and stably position and fix on the surface of the bundled material before operation, affecting the convenience and reliability of operation; some solutions do not adequately consider the protection of the bundled material surface, and the hard contact between the tool and the steel coil may still cause scratches on the surface of the bundled material. Utility Model Content

[0004] In view of this, the present invention proposes a unbundling device. By setting at least two adsorption heads distributed on both sides of the receiving groove on the contact surface of the outer shell, the device can quickly attach to the outside of the material to be unbundled using the principle of negative pressure adsorption. It does not require complicated mechanical clamps or fixtures and can adapt to any binding material with curved or flat surfaces of different sizes and specifications. It achieves rapid positioning and stable fixation before operation, which greatly improves the convenience and reliability of operation. At the same time, the pure adsorption fixation method avoids rigid contact with the binding material, preventing scratches on the surface of the binding material caused by the fixation operation from the source.

[0005] The technical solution of this utility model is achieved as follows: This utility model provides a unbundling device, including a shell, a clamping mechanism, a cutting mechanism, and an adsorption assembly, wherein, The outer casing is provided with a bonding surface, and the bonding surface is provided with a receiving groove; The clamping mechanism includes a pickup element that is movably disposed on the mating surface and can extend into the receiving groove; The cutting mechanism includes a shearing blade, which is movably disposed within the housing and forms a shearing structure with the pickup element; The adsorption assembly includes at least two adsorption heads, which are disposed on the bonding surface and located on both sides of the receiving groove.

Detailed Implementation

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1-5 As shown, the unbundling device of this utility model includes a shell 1, a clamping mechanism 2, a cutting mechanism 3, and an adsorption component 4.

[0020] The outer shell 1 is provided with a bonding surface 101, and a receiving groove 102 is provided on the bonding surface 101. The outer shell 1 is generally rectangular, and one side of it is provided as the bonding surface 101. The outer shell 1 can be assembled by splicing seven plates. The bonding surface 101 is formed by two plates, and a gap is left between the two plates to form the receiving groove 102. On the plates at both ends of the receiving groove 102, a certain depth needs to be formed by slotting so that the straps can be placed in the receiving groove 102 for unbundling.

[0021] The clamping mechanism 2 includes a pickup member 21, which is movably disposed on the mating surface 101 and can extend into the receiving groove 102. The clamping mechanism 2 can use the pickup member 21 to grab the strapping located in the receiving groove 102 and fix it relatively to the outer shell 1. Specifically, the pickup member 21 moves laterally, inserts itself between the strapping and the binding material, and pushes the strapping into the receiving groove 102 to realize the clamping and cutting operation of the strapping.

[0022] The cutting mechanism 3 includes a shearing blade 31, which is movably disposed within the housing 1 and forms a shearing structure with the pickup 21. The shearing blade 31 can be disposed within the housing 1 by means of hinge or sliding, so that it can move toward the receiving groove 102 or move inside the receiving groove 102. Before the shearing blade 31 moves to perform the shearing action, the shearing blade 31 and the pickup 21 are staggered in height, leaving a gap between them. A part of the strap is clamped into the gap by the pickup 21. As the shearing blade 31 moves, it gradually cuts the gap, thereby cutting the strap and realizing the unbundling.

[0023] The adsorption assembly 4 includes at least two adsorption heads 41, which are disposed on the bonding surface 101 and located on both sides of the receiving groove 102. The adsorption heads 41 are used to adsorb the outer wall of the binding material to fix the outer shell 1 to the binding material. In this embodiment, two adsorption heads 41 are used as an example. The two adsorption heads 41 are fixed to the binding material by negative pressure, so that the outer shell 1 is attached to the binding material. When the manual handheld device is used for unbundling, it can stably dock with the binding material. At the same time, without manual pressing, the picking part 21 can automatically be positioned by the adsorption action of the adsorption head 41 to pick up the binding tape, thereby saving manpower and facilitating the unbundling operation.

[0024] In some embodiments, the outer shell 1 is provided with a clearance groove, the clearance groove and the contact surface 101 are located on the same side, the adsorption head 41 includes a deformation disk 411 and a support block 412, the deformation disk 411 is disposed in the clearance groove and can shrink and deform toward the clearance groove, the support block 412 is fixed in the deformation disk 411, and the support block 412 and the contact surface 101 are located on the same plane.

[0025] Specifically, two protrusions are provided on the outer shell 1, forming a deep groove on the periphery of the outer shell 1 as a clearance groove. The clearance groove is used to install the adsorption head 41 and corresponding accessories. The deformation disk 411 can be made of deformable material such as rubber. Through its disc-shaped structure, it can completely fit the smooth outer surface of the binding material and achieve a certain degree of sealing, so that negative pressure can be applied to the surface of the binding material to form a stable negative pressure adsorption. The support block 412 serves as the overall support for the adsorption head 41, preventing the deformation disk 411 from being over-deformed, while ensuring good stability in contact between the adsorption head 41 and the surface of the binding material.

[0026] In some embodiments, the adsorption assembly 4 further includes a distribution valve 42 and a connecting pipe 43. The distribution valve 42 is fixed inside the housing 1, and the two ends of the connecting pipe 43 are respectively connected to the distribution valve 42 and the adsorption head 41.

[0027] The distribution valve 42 is used to distribute the air source pressure. An installation plate is provided inside the housing 1, and the distribution valve 42 is fixed on the installation plate. The distribution valve 42 is also provided with an air source interface, which is connected to the side wall of the housing 1 through a pipeline for connecting to an external air source. The air source can be an air compressor or other equipment. At least two connecting pipes 43 are also provided on the distribution valve 42. The connecting pipes 43 are used to connect the air path from inside the housing 1 to realize the pressure control of the adsorption head 41 by the distribution valve 42.

[0028] To facilitate manual handheld operation, the outer shell 1 is provided with two handholds 11. Both handholds 11 are located on the side opposite to the mating surface 101 and are arranged symmetrically from left to right. Specifically, the handholds 11 are U-shaped to facilitate gripping by the user. Considering the overall size and weight of the device, the two handholds 11 can be held by the user's two hands at the same time.

[0029] In addition, to facilitate the alignment of the straps during handheld operation and avoid misalignment that would prevent accurate cutting, two crosshair cursors can be set inside the outer casing 1 of this device for auxiliary alignment. The two crosshair cursors are aligned with the edge of the steel strip for auxiliary positioning.

[0030] In some embodiments, the pickup member 21 is a sheet-like structure with one side set as an inclined surface and the other side protruding from the bonding surface 101. The pickup member 21 can pick up the strap more accurately by protruding 1-3mm from the bonding surface. The inclined surface structure can push the strap into the interior of the outer shell 1 after it is picked up, so that the strap can be moved away from the binding material and provide a certain cutting space.

[0031] In some embodiments, the clamping mechanism 2 further includes a first linear drive unit 22 and a sliding seat 23. The first linear drive unit 22 is disposed inside the housing 1 and has a linear movable end. The sliding seat 23 is slidably disposed inside the housing 1 and connected to the linear movable end. The sliding seat 23 can slide along a direction perpendicular to the receiving groove 102. The picking member 21 is disposed on the sliding seat 23.

[0032] The first linear drive unit 22 can be a cylinder, which can be directly connected to the distribution valve 42 for unified air supply. The first linear drive unit 22 is horizontally placed inside the housing 1, and two slide rails are provided inside the housing 1. The two slide rails are slidably connected to the sliding seat 23 to guide the sliding seat 23. The first linear drive unit 22 can drive the pickup 21 to move linearly through the movement of the linear movable end. The movement direction of the sliding seat 23 is set perpendicular to the receiving groove 102, which also makes the pickup 21 vertical when it contacts the strap, avoiding the pressure of contact forming a component force and ensuring the stability of the pickup process.

[0033] In one specific embodiment, the shearing blade 31 is hinged inside the outer shell 1, and an arc-shaped shearing surface is provided on one side. The shearing surface faces the mating surface 101. The shearing blade 31 is hinged and has an arc-shaped shearing surface, so that it can complete the shearing by rotation. At the same time, the setting of its shearing surface can cooperate with the pickup 21 to cut from one side of the strap to the other side, and the arc surface can ensure that there is always a good shearing angle, reducing the mechanical wear of the shearing blade 31.

[0034] Alternatively, the shearing blade 31 can be directly hinged to the pickup unit 21 so that it moves synchronously with the pickup unit 21, and the shearing blade 31 performs a shearing action synchronously after the pickup unit 21 is in place.

[0035] In some embodiments, the cutting mechanism 3 further includes a second linear drive unit 32, which has a pushing end that can rotate toward the shearing blade 31 and push the shearing blade 31.

[0036] Similar to the first linear drive unit 22, the second linear drive unit 32 can be a cylinder and is connected to the distribution valve 42. The difference is that the second linear drive unit 32 is vertically arranged. It can drive the shearing blade 31 to rotate through the linear movement of the pushing end. It should be noted that since the shearing blade 31 is already hinged to the outer shell 1 and the pushing end can only move in a straight line, the pushing end is not directly connected to the shearing blade 31. Instead, it contacts the shearing blade 31 and pushes it to rotate during the linear movement.

[0037] It should be noted that a torsion spring can be installed on the shearing blade 31 to limit its position or reset it. If no torsion spring is installed, the pickup unit 21 will also push the shearing blade 31 to reset when picking up the strapping.

[0038] In one specific embodiment, a contact block 311 is provided on the shearing blade 31. The contact block 311 is located in the direction of movement of the pushing end of the second linear drive unit 32. By providing a certain distance through the contact block 311, the pushing end can directly push the shearing blade 31 to rotate. At the same time, the contact block 311 can be set to a shape with smooth transition such as rounded corners so that the pushing end can maintain stable contact during the pushing process.

[0039] In some embodiments, a limiting block 5 is also provided, which is fixed on the outer shell 1 and extends one end into the receiving groove 102. The limiting block 5 is used to abut the strap and cooperate with the pickup member 21 to clamp the strap.

[0040] The limiting block 5 is offset from the pickup part 21. Specifically, a notch can be provided on the pickup part 21, which is adapted to the limiting block 5 to avoid interference between the pickup part 21 and the limiting block 5 during movement. The limiting block 5 is used to block the other side of the strap after the pickup part 21 contacts the strap to prevent the strap from shifting. After the pickup action is completed, the limiting block 5 will be located in the notch of the pickup part 21 and work with the pickup part 21 to fix the strap.

[0041] In addition, the limiting block 5 can work with the pickup part 21 to clamp the end of the strap, so that after it is cut, the upper end of the strap springs outward, while the lower end can be fixed by the limiting block 5 and the pickup part 21. The upper end springs out under stress and does not come into contact with the operator, while the lower end springs out for a longer distance. By using the limiting block 5 and the pickup part 21 to fix it, the personal safety of the operator can be guaranteed.

[0042] In some specific embodiments, the binding material can be a rolled material such as steel coil, or a layered sheet material, and the straps can be steel straps or plastic straps, etc.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
