Description

Technical Field

[0001] This utility model relates to the field of bar packaging technology, and more specifically, to a bar packaging machine. Background Technology

[0002] After the various bars are manufactured, in order to facilitate subsequent transportation, storage and sales, the bars must be packaged into fixed-shape, fixed-length and fixed-weight bundles that meet national or international standards by a bar baling machine.

[0003] After the bar stock production is completed, in order to meet the standardized requirements of transportation, storage, and sales, the bars need to be bundled into fixed-shape, fixed-length, and fixed-weight bundles using a baling machine. The working logic of the existing bar stock baling machine is as follows: after the bars are fed to the baling line, the hydraulic cylinder drives the equipment to move downwards, triggering the feeding, pulling, twisting, and cutting processes. However, there are significant defects in actual application: the resistance during the release and retraction of the baling line is relatively large, and it is easy to encounter problems with smooth retraction; at the same time, the winding trajectory of the baling line is limited, making it difficult to achieve full circumferential wrapping of the bars, resulting in loose bundles. The above problems not only directly reduce the efficiency of bar stock baling, but also increase the incidence of failures such as jamming and wire breakage in the feeding system, affecting continuous production. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a bar baling machine, which aims to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a bar baling machine, including a support frame, on which a positioning and baling component is provided; The positioning and packaging assembly includes a positioning plate disposed on one side of the top of the support frame, a turntable rotatably connected to the positioning plate, an inclined rod disposed on the outer side of the turntable, and a material roll disposed on the inclined rod; The support frame is provided at the top of the support frame, and a bidirectional lead screw is provided in the middle of the support frame. Both ends of the bidirectional lead screw are threaded to lead cylinders, and two clamping wheels are provided at the top of the support frame.

[0006] Optionally, in one possible implementation, a connecting plate is provided at the top of the wire drum, two arc-shaped grooves are formed on the upper surface of the support frame, the connecting plate is located in the middle of the support frame and is rotatably connected to the support frame, the bottom ends of the two clamping wheels respectively pass through the arc-shaped grooves and extend to one end of the corresponding connecting plate and are rotatably connected to the connecting plate, the clamping wheels are slidably connected to the arc-shaped grooves, one end of the connecting plate is provided with an elongated hole, a sliding shaft is slidably connected in the elongated hole, the bottom end of the sliding shaft is inserted into the wire drum and is rotatably connected to the wire drum, a motor is provided in the middle of the support frame, a pulley is provided at the output end of the motor, the pulley is connected to the turntable by belt drive, one end of the inclined rod is inclined upward, and the material roll is sleeved on the inclined rod and is rotatably connected to the inclined rod, the wire drum is slidably connected to the support frame, and the bidirectional screw is rotatably connected to the support frame through a bearing; The technical effects and advantages of this utility model are as follows: The material roll can rotate freely around the inclined bar, and in conjunction with the circumferential motion of the turntable, the resistance to the release and retraction of the packing line is greatly reduced, ensuring smooth retraction. The inclined bar, combined with the rotation of the turntable, makes the packing line form a circumferential winding trajectory, with no dead angles in the binding, ensuring tight binding. Furthermore, the bidirectional screw-driven clamping wheel quickly positions the bar stock, ensuring stable and orderly winding of the packing line, shortening the single-batch packing cycle, and improving packing efficiency.

[0014] 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.

[0015] This embodiment discloses a bar baling machine, aiming to solve the technical problems of existing baling machines, such as unsmooth retraction of the baling thread, difficulty in achieving complete wrapping of the bar, low bundling efficiency, and high failure rate of the wire feeding system. As attached Figure 1 Appendix Figure 2 As shown, the bar baling machine of this embodiment includes a support frame 1, a positioning and baling assembly, and a drive mechanism. The specific structure of each component is as follows: Bit-packaging component: The support frame 1 is made of welded steel plates and has an overall portal frame structure. A support frame 6 is welded and fixed to the middle of the top crossbeam of the support frame 1, as shown in the attached diagram. Figure 4 As shown, the support frame 6 is a rectangular aluminum alloy frame, which is processed using an integrated molding process to ensure structural strength.

[0016] As attached Figure 1 Appendix Figure 3 As shown, the positioning plate 2 is a circular steel plate, which is fixed to the mounting base on one side of the top of the support frame 1 by bolts. The center of the positioning plate 2 has a bearing hole, which houses a deep groove ball bearing for rotational connection with the turntable 3.

[0017] As attached Figure 3 As shown, the turntable 3 is a circular cast iron part, and its central rotating shaft is interference-fitted with the deep groove ball bearing of the positioning plate 2 to ensure that the turntable 3 can rotate smoothly 360°; a diagonal rod 4 is welded to the outside of the turntable 3. The diagonal rod 4 is made of stainless steel and is set at a 60° angle with the turntable 3, tilted upward. As attached Figure 3 As shown, the material roll 5 is a cylindrical body made of ABS engineering plastic. Its inner diameter is larger than the outer diameter of the inclined rod 4. The material roll 5 is sleeved on the inclined rod 4 and can rotate freely around the inclined rod 4. It is used to wind the packaging line, which can be made of high-strength galvanized steel wire.

[0018] As attached Figure 5 As shown, the two-way lead screw 7 has opposite thread directions at both ends. The left section is a left-hand thread and the right section is a right-hand thread. It is mounted on the two side plates of the support frame 6 by two tapered roller bearings. The outer ring of the bearing is interference-fitted with the mounting hole of the support frame 6 to ensure that the two-way lead screw 7 can rotate stably. One end of the two-way lead screw 7 extends out of the outside of the support frame 6 and is fixed with a hand crank for easy manual adjustment, or it can be connected to a servo motor through a coupling to achieve automatic adjustment.

[0019] As attached Figure 5 As shown, the screw 8 is a cylindrical structure with an internal thread that matches the double-acting screw 7. The two screw 8 are threaded to the left and right sections of the double-acting screw 7, respectively. A slider is provided at the bottom of the screw 8. The bottom crossbeam of the support frame 6 is provided with a straight groove that matches the slider. The slider slides into the straight groove, restricting the screw 8 from rotating synchronously with the double-acting screw 7 and allowing it to move only along the axial direction of the double-acting screw 7.

[0020] As attached Figure 5 As shown, the connecting plate 9 is made of aluminum alloy plate. Two connecting plates 9 are symmetrically arranged on the top of the support frame 6. The middle part is rotatably connected to the top crossbeam of the support frame 6 through a pin shaft, ensuring that the connecting plate 9 can be rotated around the pin shaft.

[0021] As attached Figure 1 Appendix Figure 4 Appendix Figure 5 As shown, the clamping wheels 10 have a rubber-coated steel core structure, providing good elasticity and friction. The bottom shafts of the two clamping wheels 10 pass through the arc-shaped sliding grooves 11 opened at the top of the support frame 6, and are rotatably connected to one end of the connecting plate 9 via bearings. The arc-shaped sliding grooves 11 are shown in the attached figure. Figure 4 As shown, there are two symmetrically opened arc-shaped grooves that are fitted with the shaft of the clamping wheel 10 to ensure that the clamping wheel 10 can slide smoothly along the arc-shaped groove 11.

[0022] As attached Figure 5 As shown, the other end of the connecting plate 9 has an elongated hole 12, and a sliding shaft 13 is slidably connected inside it; its bottom end is inserted into the mounting hole at the top of the wire drum 8 through a bearing, and can rotate relative to the wire drum 8.

[0023] Drive mechanism: As attached Figure 1 Appendix Figure 4 As shown, a motor 14 is fixed to the middle crossbeam of the support frame 1 by bolts. The motor 14 is a three-phase asynchronous motor, model Y132S-4. The output end of the motor 14 is connected to a pulley 15 via a flat key. A driven pulley is also fixed on the bottom shaft of the turntable 3. The driving pulley 15 and the driven pulley are connected by a belt drive to ensure that the winding speed of the packing line is adapted to the bundling requirements.

[0024] The specific working principle is as follows: the bar stock to be packaged, such as round steel with a diameter of 20-50mm and a length of 6m, is conveyed to the packaging area above the support frame 6 via a conveyor roller conveyor (not shown), ensuring that the axis of the bar stock is parallel to the length direction of the support frame 6, as shown in the attached diagram. Figure 1 Appendix Figure 2 As shown, the center of gravity of the bar is located on the vertical line of the center of the support frame 1 to prevent the bar from shifting during the packaging process.

[0025] Rotating the handwheel at one end of the bidirectional lead screw 7 causes the bidirectional lead screw 7 to rotate around its axis. Since the threads at both ends of the bidirectional lead screw 7 rotate in opposite directions, and the screw drums 8 are restricted to axial movement only by the linear groove, the two screw drums 8 will move towards each other along the bidirectional lead screw 7. When the screw drums 8 move, the top sliding shaft 13 slides within the elongated hole 12 of the connecting plate 9, pushing the connecting plate 9 to rotate around the central pin. (See attached...) Figure 5 As shown, the other end of the connecting plate 9 drives the clamping wheel 10 to slide inward along the arc-shaped groove 11 at the top of the support frame 6 until the rubber layers of the two clamping wheels 10 are tightly attached to the outer surface of the bar. The clamping force is controlled by the rotation amplitude of the hand crank to ensure that the bar is clamped and does not suffer surface damage. At this time, the bar is stably positioned in the center of the packaging area.

[0026] Start motor 14. The output of motor 14 drives the drive pulley 15 to rotate, which in turn drives the driven pulley at the bottom of turntable 3 to rotate via a belt, thereby causing turntable 3 to rotate at a constant speed around the central axis of positioning plate 2; as shown in the attached figure. Figure 3 As shown, when the turntable 3 rotates, the inclined rod 4 on its outer side moves in a circular motion synchronously with the turntable 3. The material roll 5 rotates freely around the inclined rod 4 under the tension of the packing line, and the packing line wound on the material roll 5 is released at a uniform speed. Since the inclined rod 4 is tilted upward at 60° to prevent the material roll 5 from falling, the packing line will wrap around the outer surface of the bar by rotating the turntable 3. The number of wrapping turns can be controlled by the running time of the motor 14, which can achieve full wrapping of the bar and avoid dead corners in the binding.

[0027] Once the packing line has been wound to the set number of turns, motor 14 stops running; the staff manually cuts it and tightens the packing line to securely bind the bar.

[0028] The hand crank of the bidirectional lead screw 7 is rotated in the opposite direction, causing the two lead cylinders 8 to move in the opposite direction along the bidirectional lead screw 7. The connecting plate 9 is flipped in the opposite direction, and the clamping wheel 10 slides outward along the arc-shaped slide groove 11, releasing the clamp on the bar. Finally, the packaged bar is transported to the storage area through the conveyor rollers, completing one packaging cycle.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
