Description

Technical Field

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

[0002] Cable tray unwinding devices occupy an important position in the cable tray manufacturing industry. As a key piece of equipment in the raw material input stage, their structural design and operational performance have a decisive impact on the efficiency, product quality, and operational safety of the entire production line. Especially in the core aspects of unwinding stability and material limiting, existing unwinding devices have gradually revealed a series of obvious limitations and technical problems when handling metal strips for cable trays of different specifications, widths, and thicknesses.

[0003] Specifically, existing technology, such as utility model patent CN221295661U, discloses an unwinding device for cable tray production, including an unwinding machine body, a main shaft, a collar, a support plate, a lead screw, and a clamping sleeve. The movable collar drives the support plate to move, achieving clamping and adjustment of the raw material. Simultaneously, a movable baffle is provided to facilitate loading and unloading of materials. This device improves the stability of the unwinding process to a certain extent, reduces equipment costs, and enhances operational safety.

[0004] However, in practical applications, this type of unwinding device still has significant technical shortcomings, especially the lack of effective limiting and guiding mechanisms at the unwinding front end. Since the strip used in cable trays typically has a certain width and rigidity, uneven tension and inaccurate guidance during unwinding can easily lead to lateral deviation, shaking, or even jamming. This not only affects the continuity of unwinding and feeding accuracy but may also cause subsequent forming equipment to stop for adjustments, reducing overall production efficiency. More seriously, this deviation can cause edge damage and bending deformation of the strip, thus affecting the dimensional accuracy and appearance quality of the finished cable tray, and even posing safety hazards. Furthermore, traditional unwinding devices often require frequent manual adjustments to the support structure and limiting positions when dealing with strips of different widths, resulting in complex operations, high labor intensity, and difficulty meeting the demands of modern large-scale, high-precision production. Therefore, given the many shortcomings of existing technologies, we urgently need an innovative cable tray unwinding device to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cable tray unwinding device, which solves the problem that the existing technology lacks an effective limiting and guiding mechanism at the unwinding front end. Since the strip material used in cable trays usually has a certain width and rigidity, it is easy to have lateral deviation, shaking or even jamming due to uneven tension and inaccurate guidance during the unwinding process. This not only affects the continuity of unwinding and the feeding accuracy, but may also lead to the shutdown and adjustment of subsequent forming equipment, reducing the overall production efficiency.

[0006] To achieve the above objectives, this utility model provides a cable tray unwinding device, including a support frame and a mounting frame on one side of the support frame, wherein one side of the support frame and one side of the mounting frame are detachably connected.

[0007] A cable bushing is rotatably connected to the inner side of the support frame. A first limiting roller is rotatably connected to one side of the inner side of the mounting frame. A drive motor is fixedly connected to one side of the outer wall of the mounting frame by bolts. The bottom of the first limiting roller is provided with a bottom frame that is slidably connected to the inner wall of the mounting frame. A second limiting roller is rotatably connected to the inner side of the bottom frame. One end of the first limiting roller passes through the side wall of the mounting frame and is connected to the output shaft of the drive motor. One end of the first limiting roller and one end of the cable bushing are connected by a belt. A top frame is fixedly connected to one side of the top of the mounting frame. A first cylinder is fixedly connected to one side of the top of the top frame by bolts. A limiting plate is provided on the inner side of the top frame. Several limiting grooves are opened on the limiting plate. The output shaft of the first cylinder passes through the top of the top frame and is fixedly connected to the top of the limiting plate.

[0008] The bottom side of the mounting frame is fixedly connected to a second cylinder by bolts, and the output shaft of the second cylinder passes through the bottom of the mounting frame and is fixedly connected to the bottom of the base frame.

[0009] The bottom frame has sliders fixedly connected to both sides, and both sliders are slidably connected to the side wall of the mounting frame through a groove.

[0010] The mounting frame is fixedly connected to both sides of the mounting frame, and the inner side of the two connecting frames is provided with insert plates. One side of each insert plate is fixedly connected to the side wall of the support frame. The upper and lower sides of the two connecting frames are provided with insert rods, and one end of the insert rod passes through the connecting frame and the insert plate in sequence.

[0011] One end of the cable bushing is rotatably connected to the inner wall of the support frame via a rotating shaft, and the other end of the cable bushing passes through the side wall of the support frame via a bearing sleeve. One end of the first limiting roller is rotatably connected to the inner wall of the mounting frame via a rotating shaft, and the other end of the first limiting roller passes through the side wall of the mounting frame via a bearing sleeve. Both ends of the second limiting roller are rotatably connected to the inner wall of the bottom frame via rotating shafts.

[0012] Among them, wheels are fixedly connected to the four bottom corners of the support frame and the four bottom corners of the mounting frame. Pulleys are sleeved on one end of the cable shaft sleeve and one end of the first limiting roller, and the two pulleys are connected by belt winding.

[0013] This utility model discloses a cable tray unwinding device. By driving a first limiting roller with a drive motor and then driving the cable bushing via a belt, the unwinding action is actively driven and synchronously controlled, improving the stability and controllability of the unwinding process. The clamping structure between the first and second limiting rollers provides effective limiting support during cable unwinding, preventing lateral deviation and vibration, significantly improving unwinding accuracy and operational stability. Simultaneously, the sliding connection structure between the base frame containing the second limiting roller and the mounting frame allows the device to adapt to cable materials of different thicknesses, enhancing its adaptability and flexibility. Furthermore, the setting of a limiting plate and multiple limiting grooves further strengthens the guiding function at the unwinding front end, ensuring the cable maintains a stable trajectory before entering subsequent processing stages, avoiding downtime for adjustments due to deviation, and improving production efficiency. The introduction of a first cylinder not only enables automatic height adjustment of the limiting plate but also reduces the frequency of manual intervention, improving the automation level and ease of operation. In addition, the detachable connection structure between the support frame and the mounting frame facilitates maintenance, replacement, and transportation, further enhancing practicality and operability.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Please see Figure 1-6 .

[0024] A cable tray unwinding device includes a support frame 1 and a mounting frame 2 on one side of the support frame 1. The support frame 1 and the mounting frame 2 are detachably connected.

[0025] A cable bushing 6 is rotatably connected to the inner side of the support frame 1. A first limiting roller 10 is rotatably connected to one side of the inner side of the mounting frame 2. A drive motor 9 is fixedly connected to one side of the outer wall of the mounting frame 2 by bolts. The bottom of the first limiting roller 10 is provided with a bottom frame 17 that is slidably connected to the inner wall of the mounting frame 2. A second limiting roller 20 is rotatably connected to the inner side of the bottom frame 17. One end of the first limiting roller 10 passes through the side wall of the mounting frame 2 and is connected to the output shaft of the drive motor 9. One end of the first limiting roller 10 and one end of the cable bushing 6 are connected by a belt 8. A top frame 11 is fixedly connected to one side of the top of the mounting frame 2. A first cylinder 13 is fixedly connected to one side of the top of the top frame 11 by bolts. A limiting plate 12 is provided on the inner side of the top frame 11. Several limiting grooves 18 are opened on the limiting plate 12. The output shaft of the first cylinder 13 passes through the top of the top frame 11 and is fixedly connected to the top of the limiting plate 12.

[0026] First, the cable to be unwound is installed on the cable sleeve 6 inside the support frame 1, and the equipment is assembled through the detachable connection structure between the support frame 1 and the mounting frame 2. Then, the belt 8 is wound and connected between one end of the cable sleeve 6 and one end of the first limiting roller 10 to form a transmission linkage. After the drive motor 9 is started, its output shaft drives the first limiting roller 10 to rotate, which in turn drives the cable sleeve 6 to rotate synchronously through the belt 8, realizing the automatic cable unwinding operation. During the unwinding process, after the cable is released from the cable sleeve 6, it passes between the first limiting roller 10 and the second limiting roller 20 in sequence. The first limiting roller 10 is fixed inside the mounting frame 2, and the second limiting roller 20 is set inside the bottom frame 17. The bottom frame 17 and the mounting frame 2 are slidably connected, so that the second limiting roller 20 can be adjusted up and down according to the cable thickness, thereby achieving effective clamping and guiding of cables of different specifications, and playing a role in initially stabilizing the unwinding path and preventing lateral deviation. Meanwhile, a top frame 11 is provided on the top of the mounting frame 2. A first cylinder 13 is fixed to the top frame 11 by bolts. Its output shaft passes through the top frame 11 and is fixedly connected to the top of the limiting plate 12. The limiting plate 12 has multiple limiting slots 18. The appropriate limiting slot 18 can be selected according to the cable diameter for threading, further realizing precise limiting control of the front end of the cable unwinding and preventing the cable from shaking or deviating during the unwinding process. In addition, the limiting plate 12 can be adjusted up and down under the action of the first cylinder 13, which is convenient to adapt to the limiting requirements of cables of different diameters and specifications, improving the versatility and applicability of the equipment. The entire unwinding process, through the coordinated work of components such as the cable bushing 6, the first limiting roller 10, the second limiting roller 20, and the limiting plate 12, constructs a complete control system from unwinding to limiting to guiding, effectively ensuring the stability and continuity of the cable during the unwinding process and avoiding problems such as jamming and edge damage caused by uneven tension or guiding deviation.

[0027] Furthermore, a second cylinder 19 is fixedly connected to the bottom side of the mounting frame 2 by bolts, and the output shaft of the second cylinder 19 passes through the bottom of the mounting frame 2 and is fixedly connected to the bottom of the bottom frame 17. During the cable unwinding process, the height position of the bottom frame 17 can be automatically adjusted according to the change in cable thickness, thereby driving the second limit roller 20 to move up and down, so that it always maintains a suitable clamping distance with the first limit roller 10, thereby enhancing the adaptability to clamping different specifications of cables, improving the limit accuracy and unwinding stability.

[0028] Furthermore, sliders 15 are fixedly connected to both sides of the bottom frame 17, and both sliders 15 are slidably connected to the side wall of the mounting frame 2 through the slide groove 16. During the process of the second cylinder 19 driving the bottom frame 17 to move up and down, the sliders 15 slide along the slide groove 16 to ensure the guidance and stability of the bottom frame 17 during the movement process, and prevent uneven clamping force between the second limit roller 20 and the first limit roller 10 due to deviation or shaking, thereby achieving the effect of improving the stability of the structure operation and extending the service life of the equipment.

[0029] Furthermore, connecting frames 4 are fixedly connected to both sides of the mounting frame 2, and insert plates 3 are provided on the inner side of both connecting frames 4. One side of each insert plate 3 is fixedly connected to the side wall of the support frame 1. Insert rods 5 are provided on the upper and lower sides of both connecting frames 4, and one end of the insert rod 5 passes through the connecting frame 4 and the insert plate 3 in sequence. The support frame 1 and the mounting frame 2 can be quickly and detachably connected by inserting the insert rod 5 into the insert plate 3, which improves the convenience of equipment assembly and disassembly, facilitates transportation, maintenance and replacement of components of different specifications, and achieves the effect of simplifying the installation process, improving operating efficiency and on-site applicability.

[0030] Furthermore, one end of the cable sleeve 6 is rotatably connected to the inner wall of the support frame 1 via a rotating shaft, and the other end of the cable sleeve 6 passes through the side wall of the support frame 1 via a bearing sleeve. One end of the first limiting roller 10 is rotatably connected to the inner wall of the mounting frame 2 via a rotating shaft, and the other end of the first limiting roller 10 passes through the side wall of the mounting frame 2 via a bearing sleeve. Both ends of the second limiting roller 20 are rotatably connected to the inner wall of the bottom frame 17 via rotating shafts. This ensures that each roller has good rotational stability and low friction loss during operation, thereby improving transmission efficiency, reducing mechanical wear, and extending the service life of the equipment.

[0031] Furthermore, wheels 14 are fixedly connected to the four bottom corners of the support frame 1 and the four bottom corners of the mounting frame 2. Pulleys 7 are fitted onto one end of the cable sleeve 6 and one end of the first limiting roller 10, and the two pulleys 7 are connected by a belt 8. This not only gives the entire device good mobility and makes it easy to adjust the equipment position on site, but also enables the drive motor 9 to drive the first limiting roller 10 and the cable sleeve 6 to operate synchronously through the transmission of the pulleys 7 and the belt 8. This achieves the effect of improving the overall transmission coordination, reducing energy consumption and enhancing system stability.

[0032] In summary:

[0033] First, the cable to be unwound is installed on the cable sleeve 6 inside the support frame 1, and the equipment is assembled through the detachable connection between the support frame 1 and the mounting frame 2. The support frame 1 and the mounting frame 2 are respectively fixedly connected to the two sides of the connecting frame 4. The connecting frame 4 is provided with the insert plate 3, and one side of each of the two insert plates 3 is fixedly connected to the side wall of the support frame 1. At the same time, the upper and lower parts of the connecting frame 4 are provided with the insert rod 5, which passes through the connecting frame 4 and the insert plate 3 to realize quick assembly and disassembly operations. Then, the belt 8 is wound between the pulley 7 at one end of the cable sleeve 6 and the pulley 7 at one end of the first limit roller 10 to form a transmission linkage relationship. After the drive motor 9 is started, its output shaft drives the first limiting roller 10 to rotate, which in turn drives the cable sleeve 6 to rotate synchronously via the belt 8, realizing the automatic cable unwinding operation. During the unwinding process, the cable is released from the cable sleeve 6 and passes between the first limiting roller 10 and the second limiting roller 20 in sequence. The first limiting roller 10 is fixed to the inside of the mounting frame 2 and is rotatably connected to the mounting frame 2 via a rotating shaft. Its other end passes through the side wall of the mounting frame 2 through a bearing sleeve to enhance rotational stability. The second limiting roller 20 is located inside the bottom frame 17. Both ends are slidably connected to the sliding grooves 16 on the side wall of the mounting frame 2 via sliders 15, ensuring guidance and stability during movement. Simultaneously, a second cylinder 19 is fixedly connected to one side of the bottom of the mounting frame 2. Its output shaft passes through the mounting frame 2 and is fixedly connected to the bottom of the bottom frame 17. During unwinding, the height of the bottom frame 17 can be automatically adjusted according to changes in cable thickness, ensuring that the second limiting roller 20 always maintains a suitable clamping distance with the first limiting roller 10. This effectively clamps and guides cables of different specifications, preventing lateral deviation and vibration. Meanwhile, a top frame 11 is fixedly connected to the top of the mounting frame 2. A first cylinder 13 is bolted to the top of the top frame 11. Its output shaft passes through the top frame 11 and is fixedly connected to the top of the limiting plate 12. Multiple limiting grooves 18 are provided on the limiting plate 12, allowing selection of the appropriate size groove 18 for cable threading, further achieving precise limiting control of the unwinding front end. The limiting plate 12 can also be adjusted vertically under the action of the first cylinder 13 to accommodate cables of different diameters, improving the versatility and flexibility of the equipment. Furthermore, wheels 14 are fixedly connected to the four corners at the bottom of the support frame 1 and the mounting frame 2, giving the entire device good mobility and on-site adjustment capabilities, facilitating flexible layout and transportation. All rotating components, such as the cable bushing 6, the first limiting roller 10, and the second limiting roller 20, are connected to their respective support structures via shafts or bearing sleeves, ensuring stable rotational performance with low friction loss, extending service life, and improving overall transmission efficiency. Through the above-mentioned series of structural designs and the integration of functional modules, this cable tray unwinding device effectively solves several technical problems existing in the prior art.Specifically, the unwinding action is actively driven and synchronously controlled by the drive motor 9 driving the first limit roller 10, and the cable bushing 6 is driven by the belt 8, thus improving the stability and controllability of unwinding. The clamping structure between the first limit roller 10 and the second limit roller 20 provides effective limiting support during cable unwinding, preventing lateral deviation and shaking of the cable during the unwinding process, significantly improving unwinding accuracy and operational stability. The linkage structure between the second cylinder 19 and the base frame 17 allows the second limit roller 20 to automatically adjust its height according to the cable thickness, enhancing adaptability to different material specifications and improving the flexibility and applicability of the equipment. The cooperation between the slider 15 and the slide groove 16 further ensures the stability of the base frame 17 during movement, preventing damage caused by shaking. The problem of uneven clamping force is addressed; the setting of the limiting plate 12 and multiple limiting grooves 18 enhances the guiding function of the unwinding front end, avoiding subsequent equipment downtime for adjustment due to deviation, and improving production efficiency; the introduction of the first cylinder 13 not only realizes automatic height adjustment of the limiting plate 12, but also reduces the frequency of manual intervention, improving the automation level and ease of operation of the equipment; the connecting frame 4, insert plate 3 and insert rod 5 structure between the support frame 1 and the mounting frame 2 also greatly facilitates the maintenance, replacement and transportation of the equipment, further improving its practicality and operability; the design of the wheel body 14 enhances the mobility of the equipment and facilitates on-site layout adjustments; and the rotation method of each roller body using a combination of rotating shaft and bearing sleeve effectively reduces mechanical wear, improves transmission efficiency, and extends the service life of the equipment. Through reasonable structural optimization and functional integration, not only are the technical problems such as cable deviation, unstable feeding and poor adaptability in the unwinding process of traditional unwinding devices solved, but also significant advantages are shown in improving unwinding efficiency, reducing labor intensity and enhancing the degree of equipment automation. It can meet the needs of modern cable tray production lines for efficient, high-precision and continuous operation, and has good application prospects and promotion value.
