Description
Technical Field
[0001] This utility model relates to the field of baling machine technology, and in particular to a structure for securing baling ropes. Background Technology
[0002] Baling machines are indispensable strapping equipment in modern production and logistics, widely used in industries such as papermaking, textiles, food, chemicals, and building materials. They are used to quickly bundle loose, block, or boxed goods for easy handling, storage, and transportation. Taking the lifting door baling machine as an example, existing baling machines use binding ropes (usually rigid ropes) to bundle materials. In actual use, because the binding ropes are rigid, after the pusher pushes the material package out, the binding ropes cannot stay in the rope groove, resulting in loosening or retraction, affecting the smooth progress of the next baling process. Furthermore, the rope threading entrance of existing mechanisms is concealed and the path is winding, requiring operators to spend a considerable amount of time completing the initial rope attachment, impacting baling efficiency. In addition, existing baling machines lack a fixed structure for the rope ends, causing them to scatter or move with the material package, making manual knotting difficult or impossible, also affecting baling efficiency. Utility Model Content
[0003] In view of the shortcomings in the above-mentioned background technology, this utility model proposes a rope fixing mechanism for a lifting door packing machine, which solves the problem that the packing rope of the packing machine is easy to loosen or retract, affecting the packing efficiency.
[0004] The technical solution of this utility model is implemented as follows: A rope securing mechanism for a lifting door baling machine includes guardrails on both sides of the box body, forming a rope channel between two adjacent guardrails. A rope hook block is provided at one end of the guardrail corresponding to the discharge port, located on the upper side of the guardrail. A rope stop plate is also provided at one end of the guardrail on the rope coiling side of the box body, corresponding to the discharge port, located on the lower side of the guardrail and corresponding to the adjacent rope hook block below. In this embodiment, the rope hook block and rope stop plate are provided at the rope channel corresponding to the rope drop groove, effectively preventing the baling rope from shifting, folding, or even coming off during high-speed threading or turning, significantly reducing the rope jamming and detachment failure rate, and improving the baling success rate.
[0005] Further optimization involves installing rope hooks on the guardrail panel located on the side of the container's rope hook; the rope hooks are located on the outer surface of the guardrail panel. During the packing preparation stage, the rope end can be pre-attached to the rope hook, forming a temporary fixation, effectively preventing the rope end from retracting or moving with the reel, ensuring that the bundling rope is always in a ready-to-pack state, reducing the frequency of repeated rope threading, and ensuring production continuity.
[0006] Further optimization involves a strip-shaped short plate structure with both ends of the short plate curving upwards towards the side furthest from the guardrail, at an angle α of 30~60°. The 30~60° curving at both ends of the short plate forms a "U" or "V" shaped limiting groove with the middle section. After the rope end is hooked in, the curving portions on both sides effectively block the movement, significantly reducing the risk of the rope end slipping off the hook even during bag pushing, achieving reliable pre-fixation and providing stable protection for subsequent hooking actions.
[0007] Further optimized, the rope hook block is a wedge structure. The wedge surface of the rope hook block is raised upward relative to the first flat top surface of the guardrail panel. The left end face of the rope hook block has an arc groove, which is connected to the second flat top surface of the guardrail panel via a first inclined surface. Preferably, the highest point of the rope hook block is flush with the bottom surface of the adjacent guardrail panel above it; the lifting angle β of the wedge surface of the rope hook block is 10~20°. The above structural design forms a continuous action chain of "lifting—guiding—hooking" for the binding rope, improving the accuracy of the rope hook block in hooking the rope.
[0008] Further optimization involves positioning a second inclined plane at the lower side of the guardrail corresponding to the wedge surface on the side of the rope hook on the box body. This second inclined plane is parallel to the wedge surface, and the wedge surface and the adjacent second inclined plane above form a ramp. This directional ramp ensures more precise and reliable rope guidance, guaranteeing that the rope can be successfully hooked onto the rope hook block in the next step.
[0009] Further optimization involves providing a right-angle groove on the lower side of the guardrail corresponding to the wedge surface on the side of the rope coiling in the box, with the rope-blocking plate hinged in the right-angle groove; the above design can ensure that the rope path is smooth and free from jamming, and also ensure the normal operation of the rope-blocking plate.
[0010] Further optimization shows that the rope-blocking plate includes a connecting plate and a baffle. The connecting plate is fixed in the right-angle groove, and the baffle is hinged to the connecting plate. The side of the baffle corresponding to the hook rope block is an arc surface. Under the action of gravity, the baffle can rotate counterclockwise until the arc surface contacts the wedge surface of the hook rope block. At this time, the rope path is locked, and the binding rope is completely blocked in the rope groove, greatly reducing the probability of rope slippage.
[0011] Further optimization revealed that both the connecting plate and the baffle are Z-shaped structures, with the baffle hinged to the connecting plate via a pin. This achieves a perfect integration of functional layering and spatial misalignment, ensuring the normal operation of the rope-blocking plate.
[0012] Further optimization involves a rope path with a rope drop groove at one end corresponding to the material outlet and a rope hook groove at the other end. A narrow, straight path connects the rope drop groove and the rope hook groove; a ramp formed by rope hook blocks connects the narrow, straight path and the rope drop groove. Under the influence of the pusher plate, the bundling rope moves sequentially along the rope hook groove, the narrow, straight path, and the ramp to reach the rope drop groove. This ensures clear rope path guidance, stable and reliable operation, and improved packaging efficiency.
[0013] The beneficial effects of this utility model are as follows: This utility model adopts a layered limiting structure with upper and lower hook blocks and rope-blocking plates, achieving double constraint on the rope end; the hook blocks reliably hook the rope, and the rope-blocking plates cooperate with the hook blocks below, effectively preventing the rope from slipping back after tightening, especially addressing the problem of rigid binding ropes easily retracting. This ensures the rope is firmly and reliably secured, guaranteeing the stability and safety of subsequent material bundling. During the packing preparation stage, the rope end can be pre-attached to the hook for temporary fixation, effectively preventing retraction and falling, ensuring the binding rope is always ready for packing, improving knotting efficiency, and ensuring production continuity.
[0014] This utility model provides a stable and standardized conveying path for the bundling rope by setting guardrails on both sides of the box to form a clear rope channel. This effectively avoids the problem of the bundling rope deviating, folding or even coming off when it is threaded at high speed or turning, significantly reducing the failure rate of rope jamming and rope coming off, and improving the packing success rate.
[0015] This utility model achieves a comprehensive improvement in the compactness, reliability, adaptability, and economy of the rope fixing mechanism of the baling machine through the systematic integration and structural innovation of components such as rope path, rope hook block, rope stop plate, and rope hook. It shortens the baling time, reduces the overall cost, and greatly improves the baling efficiency, thus having high market value and promotion value. Attached Figure Description

Detailed Implementation
[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Example 1, as Figure 1 As shown, a rope securing mechanism for a lifting gate baling machine is disclosed. The lifting gate baling machine includes a housing 1, an internal push plate 4, and a lifting gate 5 located at the discharge port. The lifting gate is driven by a vertically arranged hydraulic cylinder for opening and closing. In this embodiment, the rope securing mechanism includes guardrails 2 on both sides of the housing 1, with multiple guardrails 2 as needed. A rope path 3 is formed between two adjacent guardrails 2, allowing the baling rope to move within the rope path under the action of the push plate. A rope hook block 21 is provided at one end of the guardrail 2 corresponding to the discharge port. The rope hook block 21 is located on the upper side of the guardrail 2, i.e., within the rope path, forming a ramp 34 for hooking the rope and preventing the baling rope from retracting along the rope path 3 and detaching from the rope drop groove. The two sides of the housing 1 are respectively a side with coiled rope and a side with a rope hook. Wherein, as... Figure 3 As shown, a rope-blocking plate 22 is also provided at one end of the guardrail plate 2 on the side of the coiled rope of the box 1, corresponding to the discharge port. The rope-blocking plate 22 is located on the lower side of the guardrail plate 2 and corresponds vertically to the rope hook block 21 adjacent below. The layered limiting structure of the rope hook block and the rope-blocking plate in cooperation with each other achieves double constraint on the rope end. The rope hook block can reliably hook the rope, and the rope-blocking plate cooperates with the rope hook block below. In particular, it effectively prevents the rope from slipping back after tightening, especially addressing the problem of the rope end on the side of the coiled rope of the box. This ensures that the rope is firmly and reliably secured, and guarantees the stability and safety of the subsequent material bag binding.
[0020] This embodiment is a preferred solution, such as Figure 2As shown, one end of the rope path 3 corresponding to the discharge port is a rope drop groove 31, and the other end is a rope hook groove 32. Between the rope drop groove 31 and the rope hook groove 32 is a narrow-slit straight path 33; between the narrow-slit straight path 33 and the rope drop groove 31 is a ramp 34 formed by the rope hook block 21. When the packing rope is pushed forward by the pusher, it sequentially travels along the rope hook groove, the narrow-slit straight path, and the ramp to reach the rope drop groove. During bundling, the rope hook extends from the rope hook groove to the side of the coiled rope, hooks the rope to the side of the box equipped with the rope hook, and then manually knots it with the rope end extending from the box in the rope drop groove. The packaged material is then pushed out by the pusher, completing the packaging. By setting guardrails on both sides of the box to form a clear rope path, a stable and standardized conveying path is provided for the bundling rope, effectively avoiding problems such as deviation, folding, or even detachment of the bundling rope during high-speed threading or turning, significantly reducing the rope jamming and detachment failure rate, and improving the packaging success rate.
[0021] Example 2, as Figure 2 As shown, a rope securing mechanism for a lifting door baler is further optimized based on Embodiment 1. In this embodiment, a rope hook 23 is provided on the guardrail plate 2 located on the rope hooker side of the housing 1. The rope hook 23 is located on the outer side of the guardrail plate 2, fixing the rope end to the outside of the guardrail plate 2. The rope hook is set on the outer side of the guardrail plate, providing a clear and open rope hanging position for initial rope threading. The operator can complete the rope end hooking without reaching into the equipment or using tools, greatly shortening the rope threading time. Figure 8 As shown, specifically, in this embodiment, the rope hook 23 is preferably a strip-shaped short plate structure, with both ends of the strip-shaped short plate structure curving upwards towards the side away from the guardrail plate 2. The curving angle α = 30~60°, and the preferred curving angle α is 35°. This avoids poor anti-detachment effect due to an excessively small angle, and weakened guiding effect due to an excessively large angle, ensuring that the rope end is hooked and fixed. The 35° curving structure at both ends of the strip-shaped short plate forms a "U"-shaped limiting groove with the middle section. After the rope end is hooked in, the curving parts on both sides constitute an effective blockage. Even if the rope has a certain traction force, it can significantly reduce the risk of the rope end slipping off from both ends of the rope hook, achieving reliable pre-fixation and providing stable protection for subsequent rope hooking operations. During the packing preparation stage, the rope end can be pre-hooked on the rope hook to form a temporary fixation, effectively avoiding the problems of retraction and falling off, ensuring that the bundling rope is always in a ready-to-pack state, improving knotting efficiency, and ensuring production continuity.
[0022] like Figure 6As shown, in this embodiment, the rope hook block 21 is a wedge structure. The wedge structure can be fixed to the guardrail by welding or integral molding. The wedge surface 211 of the rope hook block 21 is raised upward relative to the first flat top surface a of the guardrail 2. The left end face of the rope hook block 21 is provided with an arc groove 212, which is connected to the second flat top surface b of the guardrail 2 by a first inclined surface c. The lifting wedge surface of the wedge structure can smoothly lift the bundling rope away from the first flat top surface. Combined with the rope-accommodating limit of the arc groove on the left end face, a continuous action chain of "lifting - guiding - hooking" is formed. The arc groove matches the shape of the bundling rope, effectively preventing the rope end from slipping or moving laterally after hooking. Especially in high-speed packing conditions, it can ensure that each hooking action is accurate and in place, significantly improving the success rate of rope fixing. The arc groove and the second flat top surface are connected by a first inclined surface to form a smooth guide ramp. This ensures that the binding rope slides smoothly from the rope path to the hook block without any steps or sharp edges, avoiding the rope snagging, jamming, or surface scratches problems caused by traditional right-angle structures. This design reduces the resistance to threading the rope, making the rope path run more smoothly and reducing equipment failure rate and downtime frequency.
[0023] like Figure 4 As shown in the preferred embodiment, the highest point of the rope hook block 21 is flush with the bottom surface of the adjacent guardrail plate 2 above. This preferred design ensures that the rope hook block precisely fills the longitudinal gap between the upper and lower guardrail plates, without encroaching on the internal space of the rope path or interfering with the upper structure. The lifting angle β of the wedge surface 211 of the rope hook block 21 is 10~20°, preferably 14.7~15°, providing accurate guidance for the rope to fall precisely into the arc groove, thus improving the success rate of rope hooking.
[0024] In this preferred embodiment, the lower side of the guardrail 2 on the side of the hook-and-hook device of the housing 1 corresponds to the wedge surface 211 as the second inclined surface d. The second inclined surface d is set parallel to the wedge surface 211, and the wedge surface 211 and the adjacent second inclined surface d above form a ramp 34. The parallel arrangement of the wedge surface and the second inclined surface together constitutes a ramp with upper and lower double inclined surface constraints, providing a clear and continuous guiding path for the bundling rope. This double-sided limiting structure ensures that the bundling rope is always precisely constrained to the predetermined track during the threading and hooking process, effectively preventing it from jumping up and down, shifting, or deviating laterally, significantly improving the stability of the rope path and the success rate of rope securing. Moreover, the formation of a directional ramp makes the rope path guidance more precise and reliable, providing a guarantee that the rope can be successfully hooked onto the hook-and-hook block in the next step.
[0025] Example 3, as Figure 7As shown, a rope securing mechanism for a lifting door baler is further optimized based on embodiment 1 or 2. In this embodiment, a right-angle groove 24 is provided on the lower side of the guardrail plate 2 on the rope coiling side of the housing 1, corresponding to the wedge surface 211. The rope-blocking plate 22 is hinged within the right-angle groove 24. The rope-blocking plate is embedded in the right-angle groove of the guardrail plate body and hinged, realizing "integration within the plate" rather than "addition outside the plate," greatly reducing the radial space occupied by the mechanism. This design perfectly adapts to the limited installation space of the lifting door baler and avoids motion interference with adjacent components such as the rope coiling mechanism and the housing wall panel. The hinged structure design can ensure the smooth passage of the rope and realize the self-rotation of the rope-blocking plate under gravity, which can promptly secure the rope after it passes through, with fast response and good securing effect.
[0026] like Figure 9 , 10 As shown, in this embodiment, the rope-blocking plate 22 includes a connecting plate 221 and a baffle 222. The connecting plate 221 is fixed in the right-angle groove 24, and the baffle 222 is hinged to the connecting plate 221. The side of the baffle 222 corresponding to the hook rope block 21 is an arc surface. Under the action of gravity, the baffle 222 can rotate counterclockwise until the arc surface contacts the wedge surface 211 of the hook rope block 21. When the rope passes through, the baffle 222 rotates clockwise under the thrust of the rope, "opening" the rope path. After the rope passes through, it can rotate counterclockwise under the action of gravity until the arc surface is tangent to the wedge surface of the hook rope block 21, at which point the rope path is "locked." The baffle acts like a "one-way valve" for the rope path, effectively preventing the rope from retracting. The connecting plate and the baffle adopt a separate structure. The connecting plate is installed first in the right-angle groove as a fixed base, providing a precise positioning reference for the hinge shaft and ensuring that the rotation axis of the baffle maintains a precise spatial relationship with the wedge surface of the hook rope block. As a preferred design, both the connecting plate 221 and the baffle 222 are Z-shaped structures with rounded ends to avoid interference. The baffle 222 is hinged to the connecting plate 221 via a pin 223. Both the connecting plate and the baffle adopt a Z-shaped three-bend structure (upper horizontal section - middle vertical plate - lower horizontal section), achieving a perfect integration of functional layering and spatial misalignment. The upper Z-shaped section of the connecting plate is fixed to the bottom surface of the right-angle groove of the guardrail, the middle vertical plate forms a hinge lug, and the lower section naturally avoids it. The upper Z-shaped section of the baffle is a hinge lug, the middle section is a force-transmitting vertical plate, and the lower section is a working baffle with an arc surface. This "shape within a shape" design compresses the thickness of the entire rope-blocking assembly to less than 20mm, reducing the space occupied by more than 50% compared to the traditional flat stacked structure, perfectly adapting to the narrow space of the rope track. The Z-shaped structure allows all edges to naturally form rounded corners through bending, completely eliminating sharp corners.
