Description

Technical Field

[0001] This utility model relates to the field of packing and cable management technology, specifically to a cable management device for packing straps. Background Technology

[0002] In the modern packaging industry, strapping is widely used, and the feeding device is one of the key components of a strapping machine. Traditional feeding devices are prone to problems such as strapping knots, overstretching, or breakage during the feeding process, affecting packing efficiency and packaging quality. To solve this problem, a strapping feeding device has been developed to improve feeding stability, ensure a smooth packing process, and enhance the automation level and production efficiency of the overall packaging operation.

[0003] Chinese patent CN217867379U discloses a strapping device for logistics packaging, including a base. A side plate is fixedly installed on the top right side of the base's bottom wall. A limiting rod passes through the center of the side plate. A spring a is sleeved on the left side of the limiting rod near the side plate. A movable plate is fixedly installed on the left end of the limiting rod. A slider is fixedly installed at the bottom of the movable plate. The slider is placed in a slide rail, which is fixedly connected to the base. Clamping plates are placed on both the movable plate and the inner side of the left wall of the base. This utility model, by setting a semi-circular head and a bead groove, uses the spring b to exert force on the push block and support rod, and the semi-circular head abuts against the bead groove of the clamping plate. The semi-circular head provides resistance to the clamping plate, preventing the rotating rod and the inner limiting paper tube from rotating excessively due to inertia during the strapping process. This facilitates finding the end of the strapping later and is suitable for widespread promotion and use. However, there are still some shortcomings that can be improved.

[0004] 1. In this utility model, the sliding movement of the movable plate on the base is achieved through the combined use of a limiting rod and spring a. However, this structural design lacks a self-locking mechanism, and spring a and the limiting rod cannot effectively fix the movable plate. Therefore, during the wire feeding operation, the movable plate may experience continuous small vibrations. This jerking phenomenon not only affects the stability of wire feeding but may also lead to the accidental detachment of the wire feeding shaft, thereby affecting the reliability and working efficiency of the entire strapping wire feeding device.

[0005] 2. In this design, a combination of a ball groove box and a semi-circular head is used to reduce the speed of the clamping plate. It should be noted that during the rotation of the clamping plate, the semi-circular head will continuously contact the clamping plate surface and cause wear. This wear will gradually accumulate over time, thus shortening the service life of the clamping plate.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0032] 8. Three-jaw chuck. Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] The working principle of this utility model is as follows: Figures 1-5 As shown, a packing strap feeding device includes: a base 1, a support frame 2 fixedly connected to the front top of the base 1, and a support frame 3 slidably connected to the rear top of the base 1. The support frame 2 and the support frame 3 are located on the front and rear sides of the base 1, respectively, forming a pair of symmetrical structures.

[0035] The top of both support frame 1 2 and support frame 2 3 are fixedly connected to rotating frame 5. Rotating frame 5 has a rotating hole. Rotating shaft 6 is rotatably connected in the rotating hole of both rotating frame 5. Three-jaw chuck 8 is fixedly connected to the adjacent side of the two rotating shaft 6. Furthermore, a working shaft for winding the packing tape is provided in the two three-jaw chuck 8.

[0036] Thus, through the combined use of two three-jaw chucks 8 and the support frame 2 3 slidably connected to the top of the base 1, the equipment can stably limit and fix working shafts of different diameters and lengths.

[0037] Next, a drive device 4 is provided between support frame 1 2 and support frame 2 3, and the drive device 4 drives support frame 2 3 to move back and forth within a limited range.

[0038] Finally, a speed reduction device 7 is installed at the top of the support frame 2 to adjust the speed of the rotating shaft 6, so as to achieve different levels of speed reduction and ensure that the speed of the rotating shaft 6 can be adjusted according to specific needs during operation, thereby precisely controlling the release of the packing tape.

[0039] The above-mentioned structures together constitute the general appearance of the packing strap feeding device of this utility model.

[0040] In Example 1, the driving device 4 includes a protective housing 401 located between support frame 1 2 and support frame 2 3. The protective housing 401 is fixedly connected to the top of the base 1. A pushing block 402 is fixedly connected to the bottom of the front end of support frame 2 3. The pushing block 402 is inserted into the protective housing 401.

[0041] A servo motor 407 is provided on one side of the front part of the bottom wall of the protective housing 401. A worm gear 406 is fixedly connected to the output shaft of the servo motor 407. A connecting frame 408 is rotatably connected to the other end of the worm gear 406. The connecting frame 408 is fixedly connected to the bottom wall of the protective housing 401.

[0042] The top end of the worm gear 406 is engaged with a worm wheel 404. The front and rear ends of the worm wheel 404 are respectively fixedly connected to a drive shaft 405 and a threaded rod 403. Here, the front end of the drive shaft 405 is rotatably connected to the front wall of the protective housing 401, while the push block 402 is threadedly connected to the threaded rod 403.

[0043] The technical effect achieved by the technical solution comprised of the above-mentioned technical features is as follows: the servo motor 407 drives the worm gear 406 to rotate, and through the precise meshing transmission between the worm wheel 404 and the worm gear 406, the servo motor 407 indirectly causes the threaded rod 403 to rotate. During this process, the push block 402, threadedly connected to the threaded rod 403, moves accordingly, thereby driving the support frame 3 to achieve precise displacement. Thanks to the excellent self-locking characteristics of the worm wheel 404 and the worm gear 406, the support frame 3 can stably maintain its set position during equipment operation, thus ensuring the stability and reliability of the entire equipment operation.

[0044] It should be noted that corresponding fixing blocks are fixedly installed at key positions on the bottom wall of the protective shell 401 and the top of the base 1. The design of these fixing blocks is to ensure that the push block 402 can only move within a specific and limited range when pushing the support frame 2 3. This ensures both the accuracy of equipment operation and avoids interference to the operation of other components that may be caused by excessive displacement of the push block 402, thus ensuring the smooth and efficient operation of the entire wire feeding device.

[0045] In Example 2, the aforementioned speed reduction device 7 includes a transmission wheel 703 fixedly connected to the front end of the front rotating shaft 6. At the same time, an electric push rod 701 is fixedly connected to the top end of the support frame 2. A limit block 702 is fixedly connected to the top end of the electric push rod 701. The top of the limit block 702 has an arc-shaped groove.

[0046] Several reset telescopic rods 704 are fixedly connected to the inner wall of the groove in the limiting block 702. The reset telescopic rods 704 can automatically reset. A rotating wheel 705 is fixedly connected to the top of the reset telescopic rod 704. At the same time, several rotating wheels 706 are fixedly connected to the inner wall of the groove in the limiting block 702. Both rotating wheels 705 and rotating wheels 706 are used in conjunction with the transmission wheel 703.

[0047] It should be noted that each of the several rotating wheels 705 and 706 consists of a support section and a rotating wheel section. These rotating wheels 705 and 706 are arranged sequentially at intervals. It is important to note that the diameter of rotating wheel 705 is smaller than the diameter of rotating wheel 706. During the upward movement of rotating wheels 705 and 706 driven by the limiting block 702, the transmission wheel 703 will first contact rotating wheel 705 before contacting rotating wheel 706. This design ensures the sequentiality and precision of the transmission process, while also providing necessary buffering and adjustment functions for the transmission system.

[0048] The technical effect achieved by the technical solution composed of the above-mentioned technical features is as follows: When it is necessary to decelerate the front rotating shaft 6, the limiting block 702 is pushed to an appropriate height by the action of the electric actuator 701, so that the transmission wheel 703 contacts the multiple rotating wheels 705. Since the rotational potential energy on the front rotating shaft 6 is transferred to the transmission wheel 703, when the transmission wheel 703 contacts the rotating wheels 705, the rotational potential energy on the rotating shaft 6 is further transferred to the rotating wheels 705, thereby reducing the rotational speed of the rotating shaft 6 while driving the rotating wheels 705 to rotate.

[0049] If a further reduction in the rotational speed of the rotating shaft 6 is required, the electric actuator 701 will continue to push the limit block 702 upward. During this process, the transmission wheel 703 will sequentially contact different rotating wheels 705 and generate a squeezing effect, thereby pushing the rotating wheels 705 to squeeze the reset telescopic rod 704. When the transmission wheel 703 contacts multiple rotating wheels 706, the electric actuator 701 stops moving. At this time, the transmission wheel 703 will simultaneously drive the rotating wheels 705 and 706 to rotate. Through this process, the rotational energy on the transmission wheel 703 and the rotating shaft 6 is further consumed, thereby achieving a deeper level of deceleration effect.

[0050] In summary, during operation, the drive device 4 first moves the support frame 3 to a suitable position, and then the three-jaw chucks 8 on both sides are used to precisely position and fix the working shaft. During the wire feeding operation, if it is necessary to reduce the speed of the working shaft to avoid excessive stretching of the wire on the working shaft, the limit block 702 can be pushed to different heights by operating the electric actuator 701. In this way, the transmission wheel 703 can sequentially contact the rotating wheel 705 and the rotating wheel 706 to achieve different speed reduction effects, thereby precisely controlling the speed of the working shaft and ensuring the safety and efficiency of the operation.

In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
