Description

Technical Field

[0001] This utility model relates to the field of workpiece packaging technology, and in particular to the clamping mechanism of a packaging machine. Background Technology

[0002] The clamping mechanism of a baling machine is a mechanical device specifically designed for fixing and compressing steel bar binding straps. It is mainly used in construction sites or steel bar processing plants to ensure that the steel bars are firmly and neatly bundled. It can automatically adjust the clamping force according to the size and weight of the steel bar bundles and is suitable for the rapid packaging and transportation of steel bars.

[0003] Existing methods require operators to constantly move the handles to tighten the straps, making the binding process time-consuming and labor-intensive. This is especially true when dealing with large quantities of steel bar bundles, where the labor intensity for operators is high and the binding efficiency is low. In addition, manual operation makes it difficult to precisely control the tightening force of the straps, which can easily lead to the straps being too tight or too loose, affecting the stability of the steel bar bundles.

[0004] Therefore, the existing mechanisms require operators to constantly move the handles to tighten the straps, resulting in a time-consuming and labor-intensive binding process. This is especially true when handling large quantities of rebar bundles, where the operator's workload is high and binding efficiency is low. Furthermore, manual operation makes it difficult to precisely control the tightening force of the straps, easily leading to straps that are too tight or too loose, affecting the stability of the rebar bundles. A new clamping mechanism for the baling machine can be designed, improved to be an electrically or hydraulically driven automatic tightening mechanism. The tightening of the straps can be controlled by a button or foot switch, eliminating the need to move the handle. This improvement not only significantly reduces the operator's workload but also improves binding efficiency and accuracy, ensuring uniform tightening force and further enhancing the stability and transportation safety of the rebar bundles. Utility Model Content

[0005] To overcome the problem that existing mechanisms require operators to constantly move the handles to tighten the straps, resulting in a time-consuming and labor-intensive binding process, especially when dealing with a large number of steel bar bundles, the operators' labor intensity is high and the binding efficiency is low. In addition, manual operation makes it difficult to accurately control the tightening force of the straps, which can easily lead to the straps being too tight or too loose, affecting the stability of the steel bar bundles.

[0006] The technical solution of this utility model is as follows: a clamping mechanism for a baling machine, including a base frame; and a strapping assembly. A base plate is connected to the left end of the base frame. The strapping assembly is located inside the base frame and includes a ratchet, a rotating post, a retaining cylinder, a retaining groove, a rotating rod, an arc groove, a handle, a motor, a rotating plate, a roller, a return shaft, a retaining plate, and a fixing block. A ratchet is rotatably connected to the right side of the inside of the base frame. The left end of the ratchet extends to the left side of the base frame and is connected to a rotating post. The rotating post is rotatably connected to the base frame. A retaining cylinder is connected to the left end of the rotating post, and the retaining cylinder has through openings on both its front and rear sides. It has a slot, and a rotating rod is rotatably connected to the outer end of the rotating column. An arc groove is opened on the rear side of the lower end of the rotating rod. A handle is connected to the rear end of the rotating rod. A motor is connected to the right end of the base frame. The output end of the motor extends into the base frame and is connected to a rotating plate. The rotating plate is rotatably connected to the base frame. Rollers are rotatably connected to the front and rear sides inside the rotating plate. The rollers are movably connected to the arc groove. A return shaft is rotatably connected to the right end of the rotating rod. A locking plate is connected to the front end of the return shaft. The locking plate is movably connected to a ratchet. A fixing block is connected to the lower right end of the rotating rod. The fixing block is movably connected to the locking plate.

[0007] Preferably, by setting up a binding assembly, after binding the strap once, the excess strap is wrapped around the slot on the clamping cylinder. The motor is started, and the motor drives the rotating plate to rotate. The rotating plate drives the roller to rotate. The roller pushes the arc groove, causing the rotating rod to rotate on the rotating column. This drives the clamping plate to drive the ratchet to rotate. The return shaft drives the clamping plate to reset. The fixing block restricts the position of the clamping plate, so that the ratchet rotates continuously. The rotation of the ratchet drives the rotating column and the clamping cylinder to rotate, thereby achieving the effect of rotational winding.

[0008] Preferably, a grip frame is connected to the rear end of the bottom frame, and a handle is provided at the top of the grip frame.

[0009] Preferably, a lifting groove is provided on the rear left side of the bottom frame, and a lead screw is rotatably connected inside the lifting groove.

[0010] Preferably, the outer end of the lead screw is threaded with a lifting block, and the lifting block is slidably connected to the lifting groove.

[0011] Preferably, the bottom of the lifting block is connected to a pressure plate, and the top of the lead screw extends to the top of the bottom frame and is connected to a knob.

[0013] Preferably, the front and rear ends of the fixed cylinder are provided with positioning grooves, and the bottom of the base plate is provided with a groove corresponding to the position of the clamping cylinder.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up a binding assembly, after the binding strap is wrapped around the rebar once, the excess binding strap is wound into the slot of the clamping cylinder. After starting the motor, the motor drives the rotating plate to rotate. The rotating plate pushes the arc groove through the roller, causing the rotating rod to rotate on the rotating column, which in turn drives the clamping plate to push the ratchet to rotate. The return shaft resets the clamping plate, and the fixing block restricts the position of the clamping plate to ensure that the ratchet rotates continuously. The rotation of the ratchet drives the rotating column and the clamping cylinder to rotate synchronously, thereby achieving the automatic winding and tightening effect of the binding strap. This solves the problem that the existing mechanism requires the operator to constantly move the handle to tighten the binding strap, which makes the binding process time-consuming and labor-intensive. Especially when dealing with a large number of rebar bundles, the labor intensity of the operator is high and the binding efficiency is low. In addition, manual operation makes it difficult to accurately control the tightening force of the binding strap, which can easily lead to the binding strap being too tight or too loose, affecting the stability of the rebar bundle.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of a packing machine clamping mechanism, including a base frame 1 and a strapping assembly. A base plate 5 is connected to the left end of the base frame 1. The strapping assembly is disposed inside the base frame 1, and includes a ratchet 21, a rotating post 22, a clamping cylinder 23, a clamping groove 24, a rotating rod 25, an arc groove 26, a handle 27, a motor 28, a rotating plate 29, a roller 210, a return shaft 211, a clamping plate 212, and a fixing block 213. The ratchet 21 is rotatably connected to the right side of the inside of the base frame 1. The left end of wheel 21 extends to the left side of the base frame 1 and is connected to a rotating column 22. The rotating column 22 is rotatably connected to the base frame 1. The left end of the rotating column 22 is connected to a retaining sleeve 23. The retaining sleeve 23 has retaining grooves 24 extending through its front and rear sides. The outer end of the rotating column 22 is rotatably connected to a rotating rod 25. The lower rear end of the rotating rod 25 has an arc groove 26. The rear end of the rotating rod 25 is connected to a handle 27. The right end of the base frame 1 is connected to a motor 28. The output end of the motor 28 extends into the base frame 1 and is connected to a rotating plate 29. The rotating plate 29 is connected to the base frame 1. Rotary connection: Rollers 210 are rotatably connected to the front and rear sides of the interior of the rotating plate 29. The rollers 210 are movably connected to the arc groove 26. A return shaft 211 is rotatably connected to the right end of the rotating rod 25. A locking plate 212 is connected to the front end of the return shaft 211. The locking plate 212 is movably connected to the ratchet 21. A fixing block 213 is connected to the lower right side of the rotating rod 25. The fixing block 213 is movably connected to the locking plate 212. By setting the binding assembly, after binding the strap once, the excess strap is wrapped around the locking cylinder 23. Within the slot 24, the motor 28 is started, which drives the rotating plate 29 to rotate. The rotating plate 29 drives the roller 210 to rotate, and the roller 210 pushes the arc groove 26, causing the rotating rod 25 to rotate on the rotating column 22. This causes the card plate 212 to drive the ratchet 21 to rotate, and the return shaft 211 drives the card plate 212 to reset. The fixing block 213 restricts the position of the card plate 212, thereby enabling the ratchet 21 to rotate continuously. The rotation of the ratchet 21 drives the rotating column 22 and the card cylinder 23 to rotate, thus achieving the effect of rotation and winding.

[0023] Please see Figures 1-4 In this embodiment, a gripping frame 31 is connected to the rear end of the bottom frame 1, and a handle 32 is provided on the top of the gripping frame 31. The handle 32 and the gripping frame 31 facilitate gripping of the device. A lifting groove 41 is provided on the rear left side of the bottom frame 1. A lead screw 42 is rotatably connected inside the lifting groove 41. The lead screw 42 is used to assist in positioning the strap. A lifting block 43 is threadedly connected to the outer end of the lead screw 42. The lifting block 43 is slidably connected to the lifting groove 41. The rotation of the lead screw 42 drives the lifting block 43 to move vertically. The lifting block 43 is used to assist in pressing down the strap.

[0024] Please see Figures 2-4In this embodiment, the bottom of the lifting block 43 is connected to a pressure plate 44, and the top of the lead screw 42 extends to the top of the bottom frame 1 and is connected to a knob 45. Rotating the knob 45 causes the lead screw 42 to rotate in the lifting groove 41, which in turn causes the lifting block 43 to slide in the lifting groove 41. The lifting block 43 drives the pressure plate 44, which is used to press down the strap and fix one end of the strap. The knob 45 is rotatably connected to the bottom frame 1. The front left side of the bottom frame 1 is connected to a fixing cylinder 46. The fixing cylinder 46 is used to assist in positioning the strap during winding. The front and rear ends of the fixing cylinder 46 are provided with positioning grooves 47. The bottom of the bottom plate 5 is provided with a groove 48 corresponding to the position of the clamping cylinder 23. The positioning groove 47 is used to assist in positioning during winding of the strap.

[0025] During operation, first press the pressure plate 44 onto the workpiece to be bound, then turn the knob 45. The knob 45 drives the lead screw 42 to rotate within the lifting groove 41, which in turn drives the lifting block 43 to slide within the lifting groove 41. The lifting block 43 drives the pressure plate 44, which is used to press down on the binding strap and fix one end of the binding strap. After the binding strap is wrapped around the steel bar once, the excess binding strap is passed through the positioning groove 47 of the fixing cylinder 46 and then wrapped around the clamping groove 24 of the clamping cylinder 23. Start. After the motor 28, the motor 28 drives the rotating plate 29 to rotate. The rotating plate 29 pushes the arc groove 26 through the roller 210, causing the rotating rod 25 to rotate on the rotating column 22, which in turn drives the clamping plate 212 to drive the ratchet 21 to rotate. The return shaft 211 resets the clamping plate 212. The fixing block 213 restricts the position of the clamping plate 212 to ensure that the ratchet 21 continues to rotate. The rotation of the ratchet 21 drives the rotating column 22 and the clamping cylinder 23 to rotate synchronously, thereby achieving the automatic winding and tightening effect of the strap.

[0026] Through the above steps, by setting up the binding assembly, after the binding strap is wrapped around the rebar once, the excess binding strap is wrapped around the slot 24 of the clamping cylinder 23. After starting the motor 28, the motor 28 drives the rotating plate 29 to rotate. The rotating plate 29 pushes the arc groove 26 through the roller 210, causing the rotating rod 25 to rotate on the rotating column 22, which in turn drives the clamping plate 212 to push the ratchet 21 to rotate. The return shaft 211 resets the clamping plate 212, and the fixing block 213 restricts the position of the clamping plate 212 to ensure that the ratchet 21 continues to rotate. The ratchet 21 rotates, causing the rotating column 22 and the clamp 23 to rotate synchronously, thereby achieving automatic winding and tightening of the binding strap. This solves the problem that existing mechanisms require operators to constantly move the handle 27 to tighten the binding strap, resulting in a time-consuming and labor-intensive binding process. Especially when dealing with a large number of steel bar bundles, the labor intensity of operators is high and the binding efficiency is low. In addition, manual operation makes it difficult to accurately control the tightening force of the binding strap, which can easily lead to the binding strap being too tight or too loose, affecting the stability of the steel bar bundle.
