Description

Technical Field

[0001] This utility model relates to the field of strapping packaging machines, and in particular to a strapping machine with a fixed-point limiting mechanism. Background Technology

[0002] A cable tie machine is an automated packaging device specifically designed for bundling and securing items. It primarily uses plastic cable ties or other binding materials to quickly and securely bind products, packaging boxes, cable harnesses, and other items. This equipment typically includes core components such as a feeding mechanism, tensioning system, cutting device, and locking mechanism. It can automatically complete a series of actions including feeding, wrapping, tensioning, locking, and cutting, and is widely used in industries such as electronics manufacturing, logistics warehousing, food packaging, and building material bundling. Cable tie machines not only significantly improve packaging efficiency and reduce labor costs, but also ensure consistent and reliable binding force, effectively preventing loosening and damage to items during transportation and storage. They are an indispensable piece of equipment in modern automated production lines.

[0003] Existing strapping machines primarily rely on manual support of materials during packaging to ensure stability. However, this manual support can lead to instability in strapping quality. Because operators must keep their hands close to the machine's moving parts, there are safety hazards such as pinching and cutting, especially when handling heavy or sharp objects. Furthermore, prolonged repetitive bending and lifting movements can cause occupational diseases and muscle strain for operators, impacting their health and increasing the risk of equipment damage or product quality issues due to human error, thus increasing the company's safety responsibilities and potential compensation risks.

[0004] Therefore, a strapping machine with a fixed-point limiting mechanism is proposed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a strapping machine with a fixed-point limiting mechanism, which has the advantages of quickly limiting the material, ensuring its stability during strapping, and convenient overall limiting adjustment.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A strapping machine with a fixed-point limiting mechanism includes a strapping machine;

[0008] The upper end face of the strapping machine is formed with a strapping platform. Two sets of connecting seats are assembled on the upper end face of the strapping platform. The two sets of connecting seats are respectively arranged on one side of the strapping platform, and the two connecting seats are arranged opposite to each other.

[0009] A placement seat is assembled between the two connecting seats, and both placement seats are arranged in a U-shape and have a fixed point limiting mechanism inside them.

[0010] The side of the placement seat is provided with a storage groove, and the fixed-point limiting mechanism is disposed in the storage groove;

[0011] The fixed-point limiting mechanism includes two positioning columns embedded in the placement seat. The two positioning columns are arranged in parallel and each has a sliding shaft rod slidably installed inside. The end of the sliding shaft rod is connected to a positioning plate, and the ends of two adjacent positioning plates on the same side are jointly installed with a clamping plate.

[0012] Furthermore, the fixed-point limiting mechanism also includes limiting rings disposed outside the two positioning posts.

[0013] Furthermore, a compression spring is sleeved on the outside of the sliding shaft, and the two ends of the compression spring are tightly pressed between the limiting ring and the positioning plate.

[0014] Furthermore, the positioning plate is threaded with a plurality of positioning pins, and the clamping plate is detachably assembled with the positioning plate via the positioning pins.

[0015] Furthermore, the connecting seat has a threaded hole facing the upper surface of the strap platform, and the connecting seat is equipped with bolts and is detachably mounted on the upper surface of the strap platform by means of the bolts.

[0016] Furthermore, the bottom of the belt-bearing machine is provided with four sets of omnidirectional wheels arranged in a rectangular pattern, and each of the four sets of omnidirectional wheels is equipped with a brake.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. This strapping machine with a fixed-point limiting mechanism achieves adaptive positioning and clamping of items of different specifications through innovative mechanical structure design. The fixed-point limiting mechanism features two parallel positioning posts, with a sliding shaft connected to a positioning plate at its end. Two adjacent positioning plates on the same side are fitted with a clamping plate, forming a linked clamping system. When an item is placed in the storage slot, a compression spring automatically compresses under the weight of the item, driving the sliding shaft to slide within the positioning posts. This causes the positioning plate and clamping plate to precisely conform to the item's surface, achieving automatic positioning. A limiting ring effectively controls the sliding stroke, preventing over-clamping and damage, while the compression spring's buffering effect ensures a gentle and stable clamping force. This design eliminates the cumbersome manual support required in traditional strapping operations, significantly improving work efficiency and positioning accuracy, making it particularly suitable for mass production and standardized environments.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] First embodiment;

[0027] Reference Figure 1-4 As shown, a preferred embodiment of the present invention is a strapping machine with a fixed-point limiting mechanism, including a strapping machine 1;

[0028] The upper end face of the belt tensioning machine 1 forms a belt tensioning platform 2. Two sets of connecting seats 3 are assembled on the upper end face of the belt tensioning platform 2. The two sets of connecting seats 3 are respectively located on one side of the belt tensioning platform 2, and the two connecting seats 3 are arranged opposite to each other.

[0029] A placement seat 4 is installed between the two connecting seats 3. Both placement seats 4 are U-shaped and have a fixed-point limiting mechanism 5 inside them.

[0030] The side of the placement seat 4 is provided with a storage groove 41, and the fixed-point limiting mechanism 5 is set in the storage groove 41;

[0031] The fixed-point limiting mechanism 5 includes two positioning posts 51 embedded in the placement seat 4. The two positioning posts 51 are arranged in parallel and each of them has a sliding shaft rod 52 slidably installed inside. The end of the sliding shaft rod 52 is connected to a positioning plate 55, and the ends of two adjacent positioning plates 55 on the same side are jointly installed with a clamping plate 56.

[0032] In this embodiment, the two connecting seats 3 are arranged opposite each other, forming a symmetrical support structure. A placement seat 4 is installed between each of the two connecting seats 3. Both placement seats 4 adopt a U-shaped structure design, which can effectively accommodate and support the items to be strapped, and a core positioning and limiting mechanism 5 is installed inside. A storage groove 41 is provided on the side of the placement seat 4 to provide space for placing items, while the positioning and limiting mechanism 5 is located within the storage groove 41, facilitating direct positioning and fixing of the items. Specifically, the positioning and limiting mechanism 5 includes two positioning posts 51 embedded within the placement seat 4. The two positioning posts 51 are arranged in parallel, forming a stable guide base. A sliding shaft 52 is slidably installed within each post, and a positioning plate 55 is connected to the end of each sliding shaft 52. A clamping plate 56 is installed at the ends of two adjacent positioning plates 55 on the same side. Through this linkage design, the clamping plate 56 can achieve synchronous movement, stably and evenly clamping the items, ensuring positioning accuracy during the strapping process.

[0033] Second embodiment;

[0034] Reference Figure 3-4 As shown, the fixed-point limiting mechanism 5 also includes a limiting ring 53 disposed outside the two positioning posts 51.

[0035] In this embodiment, the limiting ring 53 physically restricts the sliding stroke of the sliding shaft 52 to prevent it from extending or retracting excessively, thereby ensuring that the clamping plate 56 always moves within a preset safe range. This protects the mechanism itself from overload damage and avoids clamping instability or damage to items caused by excessive stroke, thus improving the reliability and service life of the equipment.

[0036] Third embodiment;

[0037] Reference Figure 3-4 As shown, a compression spring 54 is sleeved on the outside of the sliding shaft 52, and the two ends of the compression spring 54 are tightly pressed between the limiting ring 53 and the positioning plate 55.

[0038] In this embodiment, when an external force is applied to the clamping plate 56 and pushes the positioning plate 55 to move, the compression spring 54 is compressed, storing elastic potential energy; when the external force is removed, the compression spring 54 releases energy, driving the sliding shaft 52 and the positioning plate 55 to automatically return to their original positions, causing the clamping plate 56 to release the item. This not only achieves an automatic reset function, reducing manual intervention, but also the buffering effect of the compression spring 54 can effectively absorb the impact force generated during clamping and releasing, making the operation smoother and gentler, adapting to the strapping needs of items with different hardness or fragility.

[0039] Fourth embodiment;

[0040] Reference Figure 3-4 As shown, the positioning plate 55 is threaded with several positioning pins 57, and the clamping plate 56 is detachably assembled with the positioning plate 55 through the positioning pins 57.

[0041] In this embodiment, a plurality of positioning pins 57 are threaded onto the positioning plate 55, and the clamping plate 56 is detachably assembled to the positioning plate 55 via these positioning pins 57. This connection method allows operators to quickly replace different models or worn clamping plates 56 according to different specifications of strapped items, such as different sizes, shapes, or materials, greatly improving the adaptability and flexibility of the equipment.

[0042] Fifth embodiment;

[0043] Reference Figure 3-4 As shown, the connecting seat 3 and the upper end face of the strap platform 2 are provided with threaded holes. The connecting seat 3 is equipped with bolts and is detachably mounted on the upper part of the strap platform 2 by means of the bolts.

[0044] In this embodiment, the connecting seat 3 and the upper surface of the strapping platform 2 are provided with threaded holes, and bolts are mounted on the connecting seat 3, allowing it to be detachably mounted on the top of the strapping platform 2. This design allows the spacing between the two connecting seats 3 to be flexibly adjusted according to the length of the item to be strapped. Simply loosen the bolts, move the connecting seat 3 to the desired position, and then tighten it again. This adapts to strapping operations of various specifications of items from short to long, enhancing the versatility of the equipment. At the same time, the detachable design also facilitates the installation, disassembly, or later maintenance of the entire placement seat 4 and the fixed-point limiting mechanism 5 module, improving the modularity and ease of use of the overall equipment.

[0045] Sixth embodiment;

[0046] Reference Figure 1-2 As shown, the bottom of the belt tensioning machine 1 is provided with four sets of universal wheels 11 arranged in a rectangular pattern, and each set of universal wheels 11 is equipped with a brake.

[0047] In this embodiment, the design of the casters 11 allows operators to easily move the entire belt-tying machine 1 to different work locations or production lines within the workshop, flexibly adapting to changes in production layout and greatly improving the equipment's mobility and space utilization. The brakes equipped on each caster 11 ensure that the equipment is firmly locked during positioning operations, preventing accidental movement due to vibration or external forces during belt-tying, thus guaranteeing the stability and operational safety of the work platform. This is particularly suitable for production environments requiring high-frequency movement and precise positioning.

[0048] Specific implementation process

[0049] Step 1: The operator first uses the brakes on the casters 11 to secure the strapping machine 1 in the designated position, ensuring equipment stability. The connecting seat 3 is then fixed to a suitable position on the upper surface of the strapping platform 2 using bolts. Next, the operator carefully places the material to be strapped into the storage slots 41 of the two placement seats 4. The weight of the material naturally presses against the fixed-point limiting mechanism 5, causing the compression spring 54 to compress and shorten. The sliding shaft 52 slides downward within the positioning column 51, moving the positioning plate 55 downward, causing the clamping plate 56 to gradually approach the material and form a preliminary limiting state.

[0050] Step 2: After the material is fully placed in place, the compression spring 54 is further compressed under the weight of the material, and the sliding shaft 52 continues to slide within the positioning post 51 to the appropriate position. At this time, the limiting ring 53 restricts the sliding range and prevents the sliding shaft 52 from sinking excessively. The positioning plate 55 precisely fits the material surface as the sliding shaft 52 moves, and the clamping plate 56 connected by the positioning screw 57 on the same side firmly clamps the material from both sides.

[0051] Step 3: After the material is securely fixed by the fixed-point limiting mechanism 5, the operator starts the strapping machine 1 to perform automatic strapping operations. Since the material has been reliably limited in the storage slot 41 by the clamping plate 56, no manual support is required during the strapping process. The strapping machine 1 can automatically complete a series of actions such as feeding, winding, tensioning, locking and cutting according to the preset program.
