Description
Technical Field
[0001] The present application relates to the technical field of strapping equipment, and in particular to a strapping machine with a strapping belt offset mechanism. Background Art
[0002] Currently, strapping machines are used to bundle bar materials (such as rebar and steel pipes). These are typically equipped with an offset mechanism. This offset drive precisely adjusts the position of the strapping straps based on the specific conditions of the cargo, allowing the strapping machine to better adapt to various cargo strapping requirements. For example, for longer bar materials, the offset drive allows the strapping straps to be precisely positioned along the length of the bar, achieving segmented lashing and improving the strength of the lashing.
[0003] Existing strapping machines typically consist of a wire feeding mechanism, a tightening mechanism, and a twisting mechanism. The wire feeding mechanism is driven by a motor and a series of transmission devices, such as gears and sprockets, to precisely control the length and speed of the tying wire, and then place the tying wire around the outside of the rods to be tied. Once the tying wire has wrapped around the rods, the tightening mechanism begins to operate. This mechanism primarily uses hydraulic or pneumatic devices to generate a strong pulling force, tightening the tying wire and clamping the rods together. The tightened tying wire needs to be twisted to secure it. The twisting mechanism crosses the two ends of the tying wire and twists them together to form a secure knot. This process is sometimes accomplished using a mechanical rotating arm, which rotates at a specific angle and number of turns to tighten the tying wire, allowing the rods to be stably bundled together.
[0004] The above-mentioned prior art solutions have the following drawbacks: the strong knot protrusions formed after the tying wire is tightened may scratch workers during the transportation of the rods. Utility Model Content
[0005] In order to prevent the knots of the tying wire from scratching people and to improve the safety of bar transportation, the present application provides a tying machine with a tying belt offset mechanism.
[0006] The above technical objectives of this application are achieved through the following technical solutions:
[0007] A strapping machine with a strapping belt offset mechanism includes a base, which is placed at the output end of the strapping machine, and the base includes a left support part and a right support part, which are respectively placed on both sides of a rod; a support frame is provided on the base, and the support frame is generally U-shaped with an opening facing downward, and the two ends of the support frame are fixedly connected to the left support part and the right support part respectively; a blocking plate is provided on the top plate in the horizontal direction of the top wall of the support frame, and the blocking plate is fixedly connected to the top wall of the support frame; when the rod completes the binding operation and moves toward the output end of the strapping machine, the blocking plate is used to bend the knot of the strapping wire.
[0008] By adopting the above solution, when the bars are completed in the binding operation and are moved to the output end of the strapping machine, the blocking plate can gradually bend the knot of the binding wire toward the upper surface of the bar, thereby reducing the height of the firm knot protrusion formed after the binding wire is tightened, preventing the knot of the binding wire from scratching people, and achieving the effect of improving the safety of the bar during transportation.
[0009] Furthermore, the support plates on both sides of the support frame in the vertical direction are telescopic plates, and each telescopic plate includes a sleeve plate, an inner plate and a top screw. The bottom wall of the sleeve plate is fixedly connected to the base, and a sliding cavity is opened inward on the side of the sleeve plate away from the base. The inner plate is inserted into the sliding cavity, and the inner plate can slide up and down along the sliding cavity; the top plate in the horizontal direction of the top wall of the support frame is fixedly connected to the two inner plates, and the top screw passes through the side wall of the sliding cavity and abuts against the inner plate; the inner plate slides along the sliding cavity to control the distance between the blocking plate and the upper surface of the rod.
[0010] By adopting the above scheme, the distance between the blocking plate and the upper surface of the rod is controlled by controlling the sliding of the inner plate along the sliding cavity, so the position of the blocking plate can be adjusted according to the height of the rod, so that the device can be suitable for binding rods of different specifications and quantities.
[0011] Furthermore, a driving member is provided on the left support part, the fixed end of the driving member is connected to the left support part, and the output end of the driving member is connected to the inner plate close to the left support part. When the output end of the driving member is extended or retracted, it drives the inner plate to slide up and down along the sliding cavity.
[0012] Furthermore, the left support portion is provided with an inwardly recessed slide groove along the width direction, the slide groove and the sleeve plate are perpendicular to each other, and the bottom wall of the driving member is fixedly connected with a slider, which is inserted in the slide groove and can slide back and forth along the slide groove; the output end of the driving member is fixedly connected with a plug-in plate, and the side wall of the inner plate is provided with a plug-in hole corresponding to the plug-in plate, and when the plug-in plate is plugged into the plug-in hole, the output end of the driving member is connected to the inner plate; the slider extends in a direction away from the sleeve plate with a fixing portion, and a fixing member is threadedly connected to the fixing portion, and the fixing member passes through the fixing portion and abuts against the bottom wall of the slide groove; the output end of the driving member is coupled with the output end of the strapping machine.
[0013] By adopting the above scheme, when the plug-in plate and the plug-in hole are plugged in and matched, the output end of the driving member and the inner plate are in a connected state. At this time, the relative position relationship between the inner plate and the sliding cavity can be controlled by the driving member; and because a slider is provided, the driving slider can be driven to move in the slide groove to drive the plug-in plate and the plug-in hole to separate through the driving member, so that the driving member is separated from the plug-in hole; therefore, when the relative position relationship between the inner plate and the sliding cavity is determined, the driving member is controlled to separate from the inner plate, thereby avoiding damage to the support frame and the driving member in the process of bending the knot of the tying wire.
[0014] Furthermore, a accommodating cavity is opened upward on the bottom wall of the top plate in the horizontal direction of the top wall of the support frame, and a first sensing piece is fixedly connected to the top wall of the accommodating cavity; a moving block is also provided in the accommodating cavity, and the upper surface of the moving block near the positions on both sides is fixedly connected to the limiting rods, and the end of each limiting rod facing away from the moving block passes through the top wall of the accommodating cavity and can slide relative to the top wall of the accommodating cavity; a second sensing piece is fixedly connected to the upper surface of the moving block; the first sensing piece and the second sensing piece are both coupled to the input end of the processor on the strapping machine; when the first sensing piece and the second sensing piece abut, a signal will be transmitted to the processor, and the processor will control the extension and contraction amount of the output end of the driving member.
[0015] By adopting the above scheme, the driving member is started, and the driving member can drive the inner plate to move toward the bottom wall of the sliding cavity. When the moving block abuts the upper surface of the rod, the driving member continues to drive the inner plate to move toward the bottom wall of the sliding cavity until the moving block is completely retracted into the accommodating groove. At this time, the second sensing plate abuts the first sensing plate, and the first sensing plate transmits the signal to the processor. The processor drives the inner plate to move away from the accommodating groove by a distance that is the thickness of the binding wire. In this way, the bundled rod can be prevented from moving toward the output end of the strapping machine; the top wall of the connecting frame interferes with the position of the binding wire hoop rod, so that it can only interfere with the knot of the binding wire.
[0016] Furthermore, a limiting block is provided at one end of each limiting rod away from the moving block, and the limiting block is used to prevent the limiting rod from escaping through the top wall of the support frame.
[0017] Furthermore, the side wall of the accommodating cavity is recessed inward to form a locking groove; the side wall of the moving block is recessed inward to form a pushing groove corresponding to the locking groove, and an elastic member is provided in the pushing groove; one end of the elastic member is fixedly connected to the bottom wall of the pushing groove, and the other end is provided with a locking pin; the locking pin is semicircular as a whole, the flat end of the locking pin is fixedly connected to the elastic member, and the locking pin is partially buried in the pushing groove.
[0018] By adopting the above solution, when the moving block is completely retracted into the accommodating groove, the locking pin is exactly opposite to the locking groove, and the elastic member pushes the locking pin to engage with the locking groove under its own elastic action, so that the relative position relationship between the moving block and the accommodating groove is locked, preventing the moving block from falling out of the accommodating groove under the action of gravity.
[0019] Furthermore, the top wall of the blocking plate is provided with an arc-shaped plate, the bottom wall of the arc-shaped plate is fixedly connected to the blocking plate, and the top wall of the arc-shaped plate is bent toward a side close to the input end of the strapping machine.
[0020] By adopting the above solution, the provision of the arc-shaped plate can assist the blocking plate in bending the knot.
[0021] In summary, this application has the following technical effects:
[0022] 1. With this machine body, when the bars are tied and moved toward the output end of the strapping machine, the blocking plate can gradually bend the knot of the tying wire toward the upper surface of the bars, reducing the height of the firm knot protrusion formed after the tying wire is tightened, preventing the knot of the tying wire from scratching people, thereby improving the safety of bar transportation;
[0023] 2. By providing a slider, the slider is driven to move in the slide groove, which can drive the plug-in plate and the plug-in hole to separate through the driving member, so that the driving member is separated from the plug-in hole; therefore, when the relative position relationship between the inner plate and the slide cavity is determined, the driving member is controlled to separate from the inner plate, thereby preventing the support frame from being damaged in the process of bending the knot of the tying wire and damaging the driving member;
[0024] 3. By setting up a first sensing plate and a second sensing plate; the second sensing plate abuts against the first sensing plate, the first sensing plate transmits a signal to the processor, and the processor drives the inner plate to move away from the accommodating groove by a distance that is the thickness of the binding wire. In this way, it can avoid that the bundled rods move toward the output end of the strapping machine; the top wall of the connecting frame interferes with the position of the binding wire hoop rods, so that it can only interfere with the knot of the binding wire.
