Description

Technical Field

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

[0002] Copper pipes are characterized by their strength and corrosion resistance, and are frequently used in water supply, heating, and cooling systems. They are also commonly used in the installation of water heaters. However, during production and processing, copper pipes are usually wound together for easy storage, requiring manual unwinding for use, which is inconvenient. Therefore, unwinding devices for copper pipes were invented. However, with continuous technological advancements, the requirements for these unwinding devices have become increasingly demanding, rendering existing devices inadequate. Thus, unwinding devices are now necessary to loosen the coiled copper pipes during the production and processing of copper pipes.

[0003] Existing unwinding devices have the following shortcomings in use: While traditional unwinding devices can unwind copper tubes, the copper tubes accumulate significant elastic potential energy during the unwinding process due to their prolonged coiled state. When the unwinding device begins operation and the copper tube gradually unwinds, this elastic potential energy is suddenly released, causing the copper tube to spring open at an extremely high speed. If the operator fails to react correctly in time, they are highly likely to be struck by the springing copper tube, resulting in personal injury. Furthermore, the springing copper tube may also pose a threat to other equipment or personnel in the surrounding environment, further exacerbating the safety risks. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability of traditional unwinding devices to unwind copper tubes. While these devices can unwind copper tubes, the copper tubes, being in a wound state for a long time, accumulate significant elastic potential energy. When the unwinding device starts working and the copper tube gradually unfolds, this elastic potential energy is suddenly released, causing the copper tube to spring open at an extremely high speed. If the operator fails to react correctly in time, they are highly likely to be hit by the springing copper tube, causing personal injury. Furthermore, the springing copper tube may also pose a threat to other equipment or personnel in the surrounding environment, further exacerbating the safety risks. Therefore, this invention proposes a copper tube unwinding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A copper tube unwinding device includes a machine base, a rotating plate rotatably connected to the top of the machine base, a first bearing fixedly mounted on the top of the rotating plate, a T-shaped rotating plate fixedly mounted on the inner wall of the inner ring of the first bearing, and a fixed cylinder for mounting copper tube coils fixedly mounted at the top center of the rotating plate. The fixed cylinder is equipped with an adjustment mechanism, which can be adjusted according to the size of the inner ring of the copper tube coil when copper tube coils of different sizes are mounted on the fixed cylinder. To prevent the copper tube from snapping open, the machine also includes a protective mechanism. During the unwinding process of the copper tube, the protective mechanism can block both sides of the copper tube roll to prevent it from snapping open.

[0006] In one possible design, the adjusting mechanism includes a second bidirectional lead screw and two adjusting plates. The fixed cylinder has a hollow structure. The bottom end of the second bidirectional lead screw is rotatably connected to the bottom inner wall of the fixed cylinder. A second bearing is embedded in the top end of the fixed cylinder. A handwheel is fixedly installed on the inner ring of the second bearing to facilitate the rotation of the second bidirectional lead screw. The bottom end of the handwheel is fixedly connected to the top end of the second bidirectional lead screw. Two second lead screw nuts are threaded onto the second bidirectional lead screw. A first hinge seat is fixedly installed on both sides of the second lead screw nuts. Two second hinge seats are fixedly installed on one side of each of the two adjusting plates. A connecting plate is hinged to the first hinge seat, and one end of the connecting plate is hinged to the second hinge seat. Through holes are opened on both sides of the fixed cylinder to facilitate the movement of the second hinge seats and the connecting plate. The second hinge seats and the connecting plate are located in the through holes.

[0007] In one possible design, the protective mechanism includes a housing, a first bidirectional lead screw, two movable blocks, two fixed posts, and two frames for blocking both sides of the copper tube coil. One side of the housing is fixedly connected to one side of the machine base. One end of the first bidirectional lead screw is rotatably connected to the inner wall of one side of the housing. A first motor for driving the first bidirectional lead screw to rotate is fixedly installed on one side of the housing. The output end of the first motor passes through one side of the housing and is fixedly connected to the other end of the first bidirectional lead screw. One side of each of the two movable blocks is slidably connected to the inner wall of one side of the housing. A first lead screw nut is embedded in one side of each movable block and is threadedly connected to the first bidirectional lead screw. One side of each of the two fixed posts is welded to one side of each of the two movable blocks. One side of each of the two frames is welded to one side of each of the two fixed posts. The frames are U-shaped. The same rotating rod is rotatably installed on the top and bottom inner walls of the frames, and there are multiple rotating rods.

[0008] In one possible design, a groove is provided on one side of the machine tool, and a second motor for driving the rotating plate to rotate is fixedly installed on the top inner wall of the groove. The output end of the second motor passes through the top of the machine tool and is fixedly connected to the bottom of the rotating plate.

[0009] In one possible design, a second short plate is welded to both sides of the rotating plate, and a first short plate is welded to both sides of the rotating plate. A nut is embedded in the first short plate, and a bolt for fixing the rotating plate and the rotating plate together is connected to the nut by an internal thread. An insertion hole is opened on the second short plate, and the bottom end of the bolt is inserted into the insertion hole.

[0010] In one possible design, a dustproof curtain for protecting the first bidirectional lead screw is fixedly installed on one side of the housing.

[0011] In this application, the copper tube coil to be unwound is placed on the fixed cylinder, and the center of the copper tube coil is aligned with the center of the fixed cylinder. The second double-acting screw is rotated using a handwheel according to the size of the inner ring of the copper tube coil. The second bidirectional lead screw rotates inside the fixed cylinder, causing the two second lead screw nuts connected to it to move up and down. When the second lead screw nuts move, they drive the connecting plate through the first hinge seat. The connecting plate, in turn, drives the two adjusting plates through the second hinge seat to move within the through holes on both sides of the fixed cylinder, bringing the two adjusting plates closer together or further apart, thus adjusting them to a position suitable for the size of the inner coil of the copper tube roll. This supports and fixes the inner coil of the copper tube roll. The first motor is started, and its output drives the first bidirectional lead screw to rotate inside the housing. When the first bidirectional lead screw rotates, the two first lead screw nuts connected to it drive two moving blocks to slide on one side of the inner wall of the housing, bringing the two moving blocks closer together or further apart. The moving blocks drive the two frames to move through the fixed column, adjusting the distance between the two frames according to the width of the copper tube roll, so that the two frames are located on both sides of the copper tube roll. This effectively counteracts the sudden release of elastic potential energy when the copper tube is unwound. When the copper tube is unwound by external mechanical pulling, the bolts need to be removed. When a second... When the motor unwinds the copper tube, rotate the bolt so that the bottom end of the bolt is inserted into the insertion hole of the second short plate, thus completing the connection between the rotating plate and the rotating plate. Then start the second motor. The output end of the second motor drives the rotating plate to rotate on the top of the machine. At the same time, the rotating plate drives the rotating plate, the fixed cylinder, and the copper tube coil sleeved on the fixed cylinder to rotate together for unwinding. The first and second motors need to be controlled by an external controller and powered by an external power supply. The type of motor can be selected according to actual needs. During the unwinding process of the copper tube, the operator needs to closely observe the unwinding situation. The first bidirectional lead screw can be protected from dust by the setting of the shielding curtain (when the moving block moves to a certain position, the moving block will lift the shielding curtain; the position not moved will be blocked by the shielding curtain, which is composed of multiple strips). The shielding curtain (i.e., the door curtain) can be made of PVC material or fabric. Of course, the specific material can be selected according to actual needs. The material, type, and specifications of the first and second bidirectional lead screws can be selected according to actual needs.

[0012] The beneficial effects of this utility model are as follows: In this utility model, the copper tube unwinding device can be flexibly adjusted according to the size of the inner ring of the copper tube roll through the adjustment mechanism. By rotating the second bidirectional screw through the handwheel, the two adjustment plates are driven to move closer or further apart, thereby achieving effective support and fixation of the inner ring of copper tube rolls of different sizes, expanding the applicability of the device and improving the versatility of the equipment. In this utility model, the copper tube unwinding device can reliably block both sides of the copper tube roll during the unwinding process through the protective mechanism, preventing the copper tube roll from springing open. The first motor drives the first bidirectional lead screw to rotate, so that the two frames are adjusted according to the width of the copper tube roll and are located on both sides of the copper tube roll, effectively dealing with the sudden release of elastic potential energy when the copper tube is unwinding, and ensuring the safety of operators and equipment. In this invention, the protective mechanism can reliably block both sides of the copper tube roll during the unwinding process, preventing the copper tube roll from springing open. The adjustment mechanism can be flexibly adjusted according to the size of the inner circle of the copper tube roll. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0016] Reference Figure 1-5 A copper tube coil unwinding device includes: a machine base 1, a rotating plate 2, a rotating plate 3, a fixed cylinder 6, an adjusting mechanism, a protective mechanism, and a driving mechanism. The machine base 1 serves as the basic support structure of the entire device, with the rotating plate 2 rotatably connected to its top. The rotating plate 3 is connected to the rotating plate 2 via a first bearing. A fixed cylinder 6 for mounting a copper tube coil is fixedly installed at the center of the top of the rotating plate 3. The adjusting mechanism is used to adjust the size according to the inner diameter of the copper tube coil to accommodate different specifications. The protective mechanism is used to abut both sides of the copper tube coil during the unwinding process to prevent the copper tube coil from springing open.

[0017] The adjusting mechanism includes a second bidirectional lead screw 17 and two adjusting plates 15. The fixed cylinder 6 has a hollow structure. The bottom end of the second bidirectional lead screw 17 is rotatably connected to the inner wall of the bottom of the fixed cylinder 6, and the top end is fixedly connected to the handwheel through a second bearing embedded in the top of the fixed cylinder 6. The handwheel is designed to facilitate the operator to rotate the second bidirectional lead screw 17.

[0018] When copper tube coils of different sizes are fitted onto the fixed cylinder 6, the operator can turn the handwheel to rotate the second double-acting screw 17 within the fixed cylinder 6. The two second screw nuts threaded onto the second double-acting screw 17 move up and down accordingly, driving the connecting plate 19 through the first hinge seat 18. The connecting plate 19, in turn, drives the two adjusting plates 15 through the second hinge seat 20 to move within the through holes 16 on both sides of the fixed cylinder 6, allowing the two adjusting plates 15 to move closer or further apart, thereby adjusting them to a position suitable for the size of the inner ring of the copper tube coil, thus supporting and fixing the inner ring of the copper tube coil.

[0019] The protective mechanism includes a housing 7, a first bidirectional lead screw 13, two moving blocks 14, two fixed posts 12, and two frame bodies 4. The housing 7 is fixedly mounted on one side of the machine base 1. One end of the first bidirectional lead screw 13 is rotatably connected to the inner wall of one side of the housing 7, and the other end is fixedly connected to the output end of the first motor 11. The first motor 11 is fixedly mounted on one side of the housing 7 and is used to drive the first bidirectional lead screw 13 to rotate.

[0020] One side of each of the two movable blocks 14 is slidably connected to one inner wall of the box 7, and each movable block 14 has a first lead screw nut embedded in one side, which is threadedly connected to the first bidirectional lead screw 13. When the first motor 11 starts, its output end drives the first bidirectional lead screw 13 to rotate inside the box 7. When the first bidirectional lead screw 13 rotates, the two first lead screw nuts threaded on it drive the two movable blocks 14 to slide on one inner wall of the box 7, so that the two movable blocks 14 move closer to or further away from each other.

[0021] The movable block 14 moves the two frames 4 via the fixed column 12, adjusting the distance between the two frames 4 according to the width of the copper tube coil, so that the two frames 4 are located on both sides of the copper tube coil. The frame 4 is U-shaped, and multiple rotating rods 5 are rotatably installed on its top and bottom inner walls. These rotating rods 5 can guide and reduce friction during the unwinding process of the copper tube. This application is for the field of loose coiling of copper tubes, but can also be used in other fields applicable to this application. Example 2

[0022] refer to Figure 1-5 An improvement based on Example 1: A copper tube unwinding device, which is used in the field of copper tube unwinding. A groove is provided on one side of the machine base 1, and a second motor 21 is fixedly installed on the inner wall of the top of the groove. The output end of the second motor 21 passes through the top of the machine base 1 and is fixedly connected to the bottom of the rotating plate 2. When it is necessary to drive the copper tube coil to rotate and unwind, the second motor 21 is started, and its output end drives the rotating plate 2 to rotate on the top of the machine base 1. At the same time, the rotating plate 2 drives the rotating plate 3, the fixed cylinder 6, and the copper tube coil sleeved on the fixed cylinder 6 to rotate together.

[0023] To enhance the connection stability between rotating plate 2 and rotating plate 3, second short plates are welded to both sides of rotating plate 2, and first short plates 9 are welded to both sides of rotating plate 3. Nuts are embedded in the first short plates 9, and bolts 8 are threaded into the internal threads of the nuts. Insertion holes are provided on the second short plates. When it is necessary to fix rotating plate 2 and rotating plate 3, the bottom end of the bolt 8 is inserted into the insertion hole of the second short plate.

[0024] To prevent dust from entering the housing 7 and affecting the normal operation of the first bidirectional lead screw 13, a shielding curtain 10 is fixedly installed on one side of the housing 7. The shielding curtain 10 can effectively protect the first bidirectional lead screw 13 from dust and extend the service life of the equipment.

[0025] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 11 and the second motor 21 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0026] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
