Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the technical field of strapping machines, and more specifically, to an intelligent control strapping machine tension adjustment device. Background Technology
[0002] In modern industrial production and logistics, strapping machines are widely used for packaging and securing various items, playing a crucial role in ensuring product integrity during transportation and storage. However, many existing strapping machines have significant shortcomings in practical use, with the lack of adjustable strap tension being a major factor hindering their efficient and precise operation.
[0003] In industrial production, different products have different characteristics and packaging requirements. For example, some precision instruments require low and stable strapping tension to avoid damage caused by excessive tension; while large and heavy goods, such as machinery and building materials, require higher strapping tension to ensure secure packaging. However, existing ordinary strapping machines cannot meet these diverse needs. Due to the lack of tension adjustment functions, they often can only strap at a fixed tension. This leads to two problems when dealing with different products: either the straps are too loose, causing the goods to loosen, shift, or even scatter during transportation, affecting product quality and transportation safety; or the straps are too tight, potentially damaging the outer packaging or even the product itself, while also increasing the risk of strap breakage and reducing packaging efficiency.
[0004] In the logistics industry, with the rapid growth of express delivery volume, the types and specifications of goods are becoming increasingly complex. However, traditional strapping machines cannot flexibly adjust tension, making it difficult for packaging personnel to adapt to the strapping requirements of different goods, reducing packaging efficiency and increasing labor costs. Moreover, strapping machines without tension adjustment functions are prone to excessive wear of strapping components during long-term use, as the strap tension cannot be adjusted according to actual conditions, shortening the equipment's lifespan and increasing the company's equipment maintenance costs.
[0005] With the increasing demands for packaging quality and efficiency across industries, the development of a strapping machine tension adjustment device capable of intelligently controlling strap tension is urgently needed. This device would not only improve the applicability of strapping machines and packaging quality but also reduce production costs, enhance enterprises' market competitiveness, and meet the diverse needs of modern production and logistics.

[0026] like Figures 1-4 As shown, it illustrates an intelligently controlled strapping machine tension adjustment device according to an embodiment of the present disclosure, comprising: A connecting plate 1 and a conveying wheel 2, wherein the conveying wheel 2 is rotatably connected to the connecting plate 1; Guide limiting component 5, the guide limiting component 5 is disposed on the connecting plate 1; The limiting wheel 3 and the tension adjusting component 4 are provided. The limiting wheel 3 is rotatably connected to the surface of the connecting plate 1, and the tension adjusting component 4 is disposed on the limiting wheel 3 and the connecting plate 1. The tension adjustment assembly 4 includes a pair of driven tooth layers 4-1, which are arranged around the outer surface of the limiting wheel 3. A pair of driving tooth layers 4-2 are provided on the surface of the limiting wheel 3. A groove 4-3 is formed around the surface of the limiting wheel 3. A pair of sliding grooves 4-4 are formed on the surface of the connecting plate 1. A movable plate 4-5 is slidably connected within the sliding grooves 4-4. A movable frame 4-6 is movably fitted within the movable plate 4-5. A locking block 4-7 is provided at the upper end of the movable frame 4-6. A spring 4-8 is fitted onto the movable frame 4-6. The connecting plate... An electric push rod 4-9 is provided at the bottom. A rack 4-10 is provided at the output end of the electric push rod 4-9. A cam 4-11 is rotatably connected to the surface of the connecting plate 1. A gear 4-12 is provided on the cam 4-11. The gear 4-12 meshes with the rack 4-10. The upper end face of the cam 4-11 slides against the bottom surface of the movable plate 4-5. A telescopic rod 4-13 is provided at one end of the rack 4-10. The output end of the telescopic rod 4-13 is fixedly connected to the surface of the connecting plate 1. A transmission sleeve 4-14 is provided on the surface of the limiting wheel 3.
[0027] In some examples, during the operation of the strapping machine, in order to achieve precise adjustment of the strapping tension by changing the pressure and avoid excessive strapping force, a tension adjustment component 4 is designed. This component includes a pair of driven teeth 4-1 arranged around the outer surface of the limiting wheel 3, which cooperate with a pair of active teeth 4-2 arranged on the surface of the limiting wheel 3 to provide a transmission basis for tension adjustment. A groove 4-3 opened around the surface of the limiting wheel 3 is slidably connected to a pair of sliding grooves 4-4 on the surface of the connecting plate 1. A movable plate 4-5 is movably fitted on the connecting plate 4-5. The movable frame 4-6 and the upper end of the movable frame 4-6 cooperate to limit and adjust the position of the limiting wheel 3. The spring 4-8 installed on the movable frame 4-6 can provide elastic support force to maintain appropriate pressure between the locking block 4-7 and the slot 4-3. The electric push rod 4-9 at the bottom of the connecting plate 1 has a rack 4-10 at its output end that meshes with the gear 4-12 on the cam 4-11 that is rotatably connected to the surface of the connecting plate 1. The upper end surface of the cam 4-11 slides against the bottom surface of the movable plate 4-5. When the electric push rod 4-9 extends or retracts, it drives the rack 4-10 to move. The rack 4-10 causes the cam 4-11 to rotate through the gear 4-12. The rotation of the cam 4-11 pushes the movable plate 4-5 to slide in the slide groove 4-4, thereby driving the movable frame 4-6 and the locking block 4-7 to move, changing the pressure of the locking block 4-7 on the limiting wheel 3. The telescopic rod 4-13 set at one end of the rack 4-10 has its output end fixedly connected to the surface of the connecting plate 1, providing guidance and stable support for the movement of the rack 4-10. The transmission sleeve 4-14 set on the surface of the limiting wheel 3 is used to contact the strapping and transmit tension. Through the coordinated operation of components such as driven tooth layer 4-1, active tooth layer 4-2, slot 4-3, slide 4-4, movable plate 4-5, movable frame 4-6, locking block 4-7, spring 4-8, electric push rod 4-9, rack 4-10, cam 4-11, gear 4-12, telescopic rod 4-13, and transmission sleeve 4-14, the tension adjustment assembly 4 can effectively adjust the tension of the strapping by changing the pressure, ensuring that the strapping process is both secure and will not damage the items due to excessive force.
[0028] like Figures 1-4 As shown in the figure, the guide limiting component 5 in this embodiment includes an elongated hole 5-1, which is formed on the surface of the connecting plate 1. An adjusting plate 5-2 is rotatably connected to the surface of the connecting plate 1. A pressing wheel 5-3 is rotatably connected to the surface of the adjusting plate 5-2. A pair of fixing blocks 5-4 are provided on the surface of the adjusting plate 5-2. A worm gear 5-5 is provided at the lower end of the movable plate 4-5. A worm 5-6 is rotatably connected between the fixing blocks 5-4. The worm 5-6 meshes with the worm gear 5-5. A screwing block 5-7 is provided at one end of the worm 5-6.
[0029] In some examples, during the strapping machine's conveying of the strapping tape, a guide and limiting assembly 5 is designed to flexibly change the conveying angle of the strapping tape to adapt to different strapping needs. This assembly includes an elongated hole 5-1 on the surface of the connecting plate 1 to provide a channel for the conveying of the strapping tape. A movable plate 4-5 is rotatably connected to the surface of the connecting plate 1, and a pressure wheel 5-3 rotatably connected to its surface can apply pressure to the strapping tape to ensure that the strapping tape remains stable during conveying. A pair of fixed blocks 5-4 are provided on the surface of the connecting plate 1, and a worm gear 5-6 rotatably connected to the fixed blocks 5-4 and a worm wheel 5-5 provided at the lower end of the movable plate 4-5 constitute an angle. The adjustable transmission structure allows the worm gear 5-6 to rotate. When the screwing block 5-7 at one end of the worm gear 5-6 is rotated, the worm gear 5-6 drives the worm wheel 5-5 to rotate, which in turn causes the movable plate 4-5 to rotate around the rotation point between itself and the connecting plate 1. This changes the angle between the movable plate 4-5 and the pressure wheel 5-3, thereby adjusting the conveying angle of the strapping. Through the coordinated work of components such as the elongated hole 5-1, the movable plate 4-5, the pressure wheel 5-3, the fixed block 5-4, the worm wheel 5-5, the worm gear 5-6, and the screwing block 5-7, the guide and limit assembly 5 can easily change the conveying angle of the strapping, meeting the usage requirements of the strapping machine in different working scenarios and improving the applicability and work efficiency of the strapping machine.
[0030] For example, such as Figure 2 As shown, the transmission sleeve 4-14 has an off-center opening 6 on its surface, and the off-center opening 6 has a threaded hole 7 on its surface.
[0031] In some examples, the presence of an offset port 6 and a threaded hole 7 facilitates connection to the motor and allows for secure maintenance of the transmission.
[0032] For example, such as Figure 2 As shown, both the upper surface of the card block 4-7 and the card slot 4-3 are toothed surfaces.
[0033] In some examples, the toothed structure improves the locking effect of the card block 4-7 and the card slot 4-3.
[0034] For example, such as Figure 1 As shown, the surface of the conveying wheel 2 is a concave structure surface, and the pressing wheel 5-3 is attached to the concave surface of the conveying wheel 2.
[0035] In some examples, the concave structural surface, in conjunction with the clamping roller 5-3, can keep the strapping inside and prevent it from coming off.
[0036] In actual use: the strapping tape is passed around the conveyor wheel 2 and the limit wheel 3. According to the strapping requirements, the screw block 5-7 on the worm gear 5-6 is rotated. The worm wheel 5-5 drives the movable plate 4-5 to rotate, adjusting the conveying angle of the pressure wheel 5-3 on the strapping tape. The electric push rod 4-9 is activated, which pushes the rack 4-10 to move. The rack 4-10 drives the gear 4-12 to rotate the cam 4-11. The cam 4-11 pushes the movable plate 4-5 to slide in the slide groove 4-4. The movable plate 4-5 drives the movable frame 4-6 and the locking block 4-7 to move, changing the pressure of the locking block 4-7 on the limit wheel 3, thereby adjusting the tension of the strapping tape. After adjustment, the strapping operation is performed.
[0037] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
