Description

Technical Field

[0001] This utility model relates to the field of rebar tying machines, and in particular to a telescopic multi-angle rebar tying machine. Background Technology

[0002] A rebar tying machine, also known as a fully automatic rebar tying machine, is a handheld, battery-powered tool for quickly tying rebar. Existing handheld rebar tying machines have the following drawbacks:

[0003] 1) Inappropriate head angle of the binding machine: The design angle of the binding machine head of existing handheld rebar binding machines has certain limitations. In actual operation, when faced with various complex rebar layouts, it is impossible to flexibly and smoothly reach the parts that need to be bound, thus severely restricting the convenience and efficiency of the binding operation. For example, in some special rebar frames, due to the head angle problem, operators often need to spend a lot of time adjusting the position and angle of the binding machine, which not only consumes energy but also greatly reduces work efficiency.

[0004] 2) Impact on component production quality: For large-area components, the lack of effective auxiliary support equipment forces operators to step on the reinforcing bars during the tying process, easily leading to deformation. Deformation directly affects the structural stability and load-bearing capacity of the entire component, severely impacting its production quality. For example, in the foundation slab reinforcement tying process of large buildings, such deformation caused by personnel stepping on the bars is common, potentially leading to safety hazards in subsequent use. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a telescopic multi-angle rebar tying machine, which separates the existing handheld rebar tying machine into a head and a body, which are connected by an adjustment mechanism to realize the adjustment of angle and length, thereby improving the convenience of rebar tying.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A telescopic multi-angle rebar tying machine is provided, which divides the existing rebar tying machine into a machine body and a machine head, which are connected by a guide adjustment assembly. The guide adjustment assembly includes a first rigid angle adjuster, one end of which is connected to the machine head, the other end of which is connected to a telescopic rod, the other end of which is connected to a second rigid angle adjuster, and the other end of which is connected to the machine body. After the steel wire is led out from the machine body, it passes through the second rigid angle adjuster, the telescopic rod, and the first rigid angle adjuster in sequence before being led out from the machine head.

[0008] Both the first rigid angle adjuster and the second rigid angle adjuster include a first mounting component and a second mounting component, which are rotatably connected and locked.

[0009] The first mounting component includes a first mounting plate, a gear is fixed to the inner wall of the first mounting plate, a rotating shaft is fixed to the outer end of the gear, and a limit plate is installed on the outer end of the rotating shaft.

[0010] The second mounting assembly includes a second mounting plate, on which a guide rod is slidably mounted. An operating lever is fixed to the outside of the guide rod. A clamping wheel is fixed to the other end of the guide rod. The clamping wheel freely passes through the rotating shaft and is directly opposite the gear. One edge of the clamping wheel engages with the gear through a locking tooth. The other end of the clamping wheel is connected to the second mounting plate through a spring.

[0011] The guide rods are in two sets.

[0012] The first mounting plate is integrally formed with the first guide cylinder on one side; the second mounting plate is integrally formed with the second guide cylinder on one side; the first guide cylinder, the second guide cylinder and other components are fixedly connected.

[0013] The first rigid angle adjuster, the telescopic rod, and the second rigid angle adjuster are all made of stainless steel.

[0014] This utility model provides a telescopic multi-angle rebar tying machine, which has the following technical effects:

[0015] 1) By installing a telescopic boom, the machine head can reach a greater distance to directly tie the rebar, eliminating the need for frequent manual trampling of the rebar. When dealing with large components, operators can extend the boom to the appropriate setting according to actual needs, easily reaching the central rebar without stepping on it, reducing the problem of rebar deformation caused by personnel trampling and effectively ensuring the production quality of the components. For example, in the rebar tying operation of large bridges, for large beam components, by adjusting the setting of the telescopic boom, operators can complete the rebar tying in the center of the component while standing at the edge, which is both safe and efficient.

[0016] 2) By setting the first rigid angle adjuster and the second rigid angle adjuster, the angle of the binding machine head can be adjusted when it is unreasonable, making the operation more convenient; and the two sets of rigid angle adjusters can ensure that the angle at the machine head is appropriate, and also make it easy to make the angle at the machine body appropriate, so as to make the operation comfortable.

[0017] Rebar tying machines are suitable for any modern construction scenario requiring the efficient, repetitive tying of large quantities of rebar at intersections. Their advantages are particularly pronounced in large, complex projects with tight deadlines or high labor costs. The telescopic pole effectively solves the problem of rebar being trampled on, and the added angle adjuster allows for tying complex joints (e.g., 1. multi-layered intersections of main bars, stirrups, additional bars, and tie bars; 2. areas with densely packed vertical main bars, stirrups, and tie bars; 3. precast component connection joints where space is limited due to denser stirrups around the sleeve; 4. components that need tying close together). It has become an indispensable tool in modern industrialized and mechanized construction. Attached Figure Description

Detailed Implementation

[0028] Taking the existing model, Yi Yongheng-Rebar Tying Machine 02, as an example, the existing rebar tying machine mainly consists of a machine casing. At the rear of the casing is a spool for winding steel wire, which can rotate. The steel wire is led out from the spool and clamped by a pair of gears. As the gears rotate, they drive the steel wire forward continuously. The wire is guided to the head of the machine casing, where an arc-shaped guide channel is provided. After moving forward through the arc-shaped guide channel, the wire bends and wraps around the intersecting rebars multiple times; at this point, locking is not yet complete. Finally, the longitudinal motor at the head of the machine casing starts, cutting the steel wire while simultaneously locking it. The tightening action is completed by the longitudinal motor driving the robotic arm to lock the steel wire and then rotating it.

[0029] like Figure 1-2 As shown, a retractable multi-angle rebar tying machine is disclosed. This application places the wire spool for winding the steel wire, the gear transmission mechanism for clamping and continuously conveying the steel wire, and the control unit of an existing rebar tying machine inside the machine body 1; and places the arc-shaped guide channel for guiding the steel wire, the longitudinal motor, and the robotic arm inside the machine head 2. A retractable and angle-adjustable guide adjustment assembly 3 for guiding the steel wire is provided between the machine body 1 and the machine head 2.

[0030] like Figure 1-2 As shown, the guide adjustment assembly 3 includes a first rigid angle adjuster 4. One end of the first rigid angle adjuster 4 is connected to the machine head 2, and the other end is connected to the telescopic rod 5. The other end of the telescopic rod 5 is connected to a second rigid angle adjuster 6, and the other end of the second rigid angle adjuster 6 is connected to the machine body 1. After the steel wire is led out from the machine body 1, it passes through the second rigid angle adjuster 6, the telescopic rod 5, the first rigid angle adjuster 4, and the machine head 2 before being led out.

[0031] like Figure 3 As shown, specifically, both the first rigid angle adjuster 4 and the second rigid angle adjuster 6 include a first mounting component 7 and a second mounting component 8.

[0032] like Figure 4 As shown, the first mounting assembly 7 includes a first mounting plate 7.1, one side of which is integrally formed with the first guide cylinder 7.2. A gear 7.3 is fixed to the inner wall of the first mounting plate 7.1, a rotating shaft 7.4 is fixed to the outer end of the gear 7.3, and a limit plate 7.5 is fixed to the outer end of the rotating shaft 7.4.

[0033] like Figure 5-6As shown, the second mounting assembly 8 includes a second mounting plate 8.1, one side of which is integrally formed with the second guide cylinder 8.2. A guide rod 8.3 is slidably mounted on the second mounting plate 8.1. An operating rod 8.5 is fixed to the outer side of the guide rod 8.3, and a clamping wheel 8.6 is fixed to the inner end of the guide rod 8.3. Both the center of the clamping wheel 8.6 and the second mounting plate 8.1 have through holes 8.7. A rotating shaft 7.4 passes through the through holes 8.7 and is limited by a limiting plate 7.5. A spring 8.4 is provided between the side of the clamping wheel 8.6 near the second mounting plate 8.1 and the second mounting plate 8.1. The spring 8.4 passes through the rotating shaft 7.4. The other side of the clamping wheel 8.6 is directly opposite the gear 7.3 and has a locking tooth 8.8 on its edge, which engages with the gear 7.3.

[0034] When it is necessary to adjust the relative angle between the first mounting component 7 and the second mounting component 8, pull the operating lever 8.5 outward. The spring 8.4 is compressed, and the retaining tooth 8.8 disengages from the gear 7.3. At this time, the first mounting component 7 and the second mounting component 8 can rotate relative to each other. Alternatively, the first mounting component 7 can be kept stationary while the second mounting component 8 can be rotated; or the second mounting component 8 can be kept stationary while the first mounting component 7 can be rotated. The relative angle between the first mounting component 7 and the second mounting component 8 changes, thus allowing for angle adjustment of the components fixedly connected to the first mounting component 7 and the second mounting component 8.

[0035] like Figure 6 As shown, preferably, the outer wall of the clamping wheel 8.6 is provided with an annular wire guide groove 8.9. The wire passes through the first guide cylinder 7.2, the wire guide groove 8.9, and then enters the second guide cylinder 8.2. In this way, the guidance of the wire is not affected regardless of whether the angle is adjusted.

[0036] The telescopic rod 5 adopts an existing conventional telescopic structure, such as the structure of the mop telescopic rod in the patent "A Mop Telescopic Rod and Mop" with application number "202020835906.6". The inner and outer connecting rods must be hollow and connected to ensure that the steel wire can pass through normally.

[0037] The guide adjustment assembly 3 consists of two sets arranged side by side, with one set of the guide adjustment assembly 3 through which the steel wire passes. During adjustment, both sets of operating levers 8.5 are pulled outwards to adjust either the machine body 1 or the machine head 2.

[0038] The guide adjustment component 3 is made of stainless steel, or alternatively, carbon fiber composite material, to ensure strength and hardness.

[0039] Working principle and process: The wire binding principle of this device is consistent with that of the corresponding existing models. However, when angle adjustment is required, such as... Figure 7-8As shown, pull the corresponding operating lever 8.5 outward to disengage the locking teeth 8.8 from the gear 7.3, then rotate the corresponding first mounting component 7 or second mounting component 8. After adjustment, release the operating lever 8.5; under the action of the spring 8.4, the locking teeth 8.8 and gear 7.3 will engage and lock, completing the angle adjustment. When length adjustment is required, simply retract the mop extension rod as per existing adjustment methods.
