Description

Technical Field

[0001] This invention relates to the field of bar bundling technology, and in particular to a suspended small-bundle bar bundling machine. Background Technology

[0002] Currently, the common methods for bundling small bundles of bar stock are manual bundling and machine bundling. Manual bundling suffers from problems such as low efficiency, inconvenience in operation, non-standard bundling, and waste of steel wire. While machine bundling improves efficiency to some extent, it also has obvious drawbacks: 1. The position of the baler head of existing bundling machines is fixed, especially the height, which cannot be adjusted. This means that when bundling bars of different specifications, the steel wire cannot be fully tightened, affecting the bundling quality; 2. The bundling process of existing bundling machines is completed on the ground, which is inconvenient for bundling and for transporting the bundled bars after bundling; 3. The degree of automation is not high, and the bundling process requires manual intervention for manual operation or handling.

[0003] Therefore, how to create a new suspended small-bundle bar baling machine is one of the important research and development topics at present. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a suspended small-bundle bar baling machine, which improves the degree of automation, is applicable to bars of different specifications, optimizes the baling method, improves the baling quality and efficiency, and reduces labor costs, thereby overcoming the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides a suspended small-bundle bar baling machine, characterized in that it includes a frame, a baling head, a baling machine base frame, a power unit, a fixed chain conveyor mechanism, a mobile chain conveyor mechanism, and a transmission mechanism;

[0006] The frame is horizontally equipped with a crossbeam, and the baling head is suspended on the crossbeam. The baling head includes at least a lifting device, a translation device, and a head box. The lifting device is used to adjust the height of the head box, and the translation device is used to push the head box to move horizontally.

[0007] The fixed chain conveyor and the mobile chain conveyor are arranged longitudinally opposite each other on the top of the baler base frame. Sprockets are provided at both ends, and the sprockets are driven by a ring chain for horizontal longitudinal conveying of bars.

[0008] The power unit and transmission mechanism are installed on the base frame of the baler. The transmission mechanism is set horizontally, with the middle part connected to the power unit for transmission, and the two ends connected to the sprockets of the fixed chain conveyor mechanism and the mobile chain conveyor mechanism respectively.

[0009] The power unit synchronously drives the fixed chain conveyor and the mobile chain conveyor through the transmission mechanism to transport the bars longitudinally to the designated position and stack them into bundles. The machine head box moves horizontally to put the steel wire around the outside of the bundled bars, and after being packaged into bundles, it returns to its horizontal position. The cycle repeats to realize the automatic bundling of the bars.

[0010] As an improvement of the present invention, the packing head also includes a moving carriage, which is suspended on the frame beam and connected to the head box body at the bottom via a lifting device. The top of the moving carriage is equipped with wheels that contact the lower flange surface of the beam, so that the moving carriage drives the lifting device and the head box body to move along the length of the beam, thereby adjusting the horizontal position of the packing head.

[0011] Furthermore, the translation device includes a first slider, a first cylinder, and a first guide rail. The first guide rail is horizontally arranged on the lower surface of the moving vehicle. The first slider is disposed on the top of the machine head housing. The first slider is slidably connected to the first guide rail. The piston rod end of the first cylinder is connected to the first slider and is used to drive the first slider and the machine head housing to reciprocate horizontally along the first guide rail.

[0012] Furthermore, the baling head also includes a raw material storage tray, a wire feeding device, a counting device, a wire unwinding device, a wire winding device, and a twisting device;

[0013] The raw material storage plate, wire feeding device, counting device, wire unwinding device and twisting device are installed inside the die head box, and the wire winding device is installed outside the die head box;

[0014] The raw material storage tray is used to wind and store steel wire. After the steel wire is wound out of the raw material storage tray, it passes through the wire feeding device and the counting device in sequence before entering the winding device. The wire feeding device is used to drive the steel wire forward, and the counting device is used to record the length of the steel wire to control the start and stop of the wire feeding device and the wire unwinding device. The winding device is circular in shape and has a clamp at the top. After the steel wire is wound around the circular ring at least once, the clamp clamps the end of the steel wire. The wire unwinding device is used to drive the raw material storage tray to reverse, thereby causing the steel wire to retract and tighten. The knotting device is located directly above the winding device and is used to cut the tightened steel wire and twist it with the end clamped by the clamp to form a knot.

[0015] Furthermore, the wire unwinding device includes a friction disc, a wire unwinding motor, and a wire unwinding cylinder. The piston rod of the wire unwinding cylinder is connected to the friction disc and is used to push the friction disc into tangential contact with the raw material storage disc. The wire unwinding motor drives the friction disc to rotate, and the friction disc drives the raw material storage disc to rotate counterclockwise through friction, thereby realizing the wire retraction and tightening.

[0016] Furthermore, the rotating shaft of the raw material storage tray is a damping shaft to reduce the inertial force during the wire feeding process, and the wire feeding device adopts a double drive wheel conveyor to increase the traction force.

[0017] Furthermore, both the fixed chain conveyor and the mobile chain conveyor are equipped with a retracting device. The retracting device includes two claw arms, which are hinged in the middle and are Y-shaped. The lower parts of the two claw arms are slidably placed in the guide groove and connected to the piston rod of the second cylinder. The second cylinder is used to push the lower parts of the two claw arms to move vertically along the guide groove, thereby causing the retracting device to open or close.

[0018] The number of guide grooves is two. The guide groove that cooperates with the gathering device on the fixed chain conveyor is vertically set on the base frame of the baler, and the guide groove that cooperates with the gathering device on the mobile chain conveyor is set on the follower bracket of the mobile chain conveyor.

[0019] Furthermore, the bottom of both ends of the mobile chain conveyor is provided with a second slider, and two transverse second guide rails are horizontally arranged on the base frame of the baler, and the second slider is slidably connected to the second guide rails;

[0020] An adjustment mechanism is provided between the mobile chain conveyor and the baler base frame. The adjustment mechanism includes a lead screw and a nut. The lead screw is horizontally arranged, passes through the mobile chain conveyor, and is mounted on the baler base frame through a bearing seat. The nut is fitted on the lead screw and fixedly connected to the mobile chain conveyor. The adjustment mechanism is used to drive the mobile chain conveyor to move horizontally and adjust its position to accommodate bars of different lengths.

[0021] Furthermore, a limiting mechanism is installed on the base frame of the baler. The limiting mechanism includes a limiting rod and a limiting cylinder. The limiting rod is fixedly connected to the piston rod of the limiting cylinder. The limiting cylinder is vertically arranged and is used to push the limiting rod up and down to block the bar at a designated position.

[0022] Furthermore, the base frame of the baler is equipped with a positioning detection mechanism to detect whether the bars are properly gathered.

[0023] With this design, the present invention has at least the following advantages:

[0024] 1. The horizontal position of the head box can be adjusted by moving the moving trolley along the frame beam. The horizontal position of the moving chain conveyor can be adjusted by the adjustment mechanism. It is suitable for bundling bars of different lengths. The vertical height of the head box can be adjusted by the lifting device. It is suitable for bundling bars of different diameters or different quantities, thus improving the bundling quality.

[0025] 2. During the binding process, the bars transported one by one are gathered together by the gathering device. The machine head box uses the translation device to make the steel wire surround and fit around the gathered bars. Then, the steel wire ends are clamped by the clamps. The wire unwinding device pulls the steel wire back and tightens it to fit the bar. Then, it is twisted and cut, making the binding more stable and secure.

[0026] 3. After bundling, the gathering device is opened and the limit mechanism is lowered. The bundled bars continue to be transported backward through the fixed chain conveyor and the mobile chain conveyor until they fall into the transfer vehicle. Compared with the traditional method of bundling on the ground, the transfer is more convenient and the work efficiency is higher.

[0027] 4. The in-place detection mechanism automatically detects whether the bars are gathered in place and controls the operation of the baling machine head. The counting device automatically records the wire length and controls the start and stop of the wire feeding device and the wire unloading device. The binding process is highly automated, reducing labor costs. Attached Figure Description

[0037] Please see Figures 1 to 7 The present invention provides a suspended small-bundle bar baling machine, including a frame 1, a baling machine base frame 2, a power unit 3, a baling head 4, a fixed chain conveyor mechanism 5, a mobile chain conveyor mechanism 6, a transmission mechanism 7, an adjustment mechanism 8, a limit mechanism 9, and a positioning detection mechanism 10.

[0038] The frame 1 includes at least one horizontally arranged crossbeam. In this embodiment, the crossbeam is made of H-beam steel and is mounted on the top of the two side columns. The crossbeam is used to suspend the packing head 4 and serves as a guide rail for the packing head 4, so that the packing head 4 can move horizontally along the length of the crossbeam.

[0039] The packing head 4 includes a head box 41, a moving vehicle 42, a lifting device 43, and a translation device.

[0040] The mobile cart 42 is suspended on the crossbeam of the frame 1, and its bottom is connected to the head unit 41 via a lifting device 43. Wheels are mounted on the top of the mobile cart 42, and these wheels contact the lower flange surface of the crossbeam, allowing the mobile cart 42 to move the lifting device 43 and the head unit 41 along the length of the crossbeam. This movement is used to adjust the horizontal position of the packing head 4 to accommodate the bundling of bars of different lengths. The lifting device 43 drives the head unit 41 to move vertically, adjusting its height to accommodate the bundling of bars of different diameters or quantities.

[0041] The translation device includes a first slider 411, a first cylinder 412, and a first guide rail 421. The first guide rail 421 is horizontally arranged on the lower surface of the moving vehicle. The first slider 411 is arranged on the top of the head unit 41. The first slider 411 is slidably connected to the first guide rail 421. The piston rod end of the first cylinder 412 is connected to the first slider 411 and is used to drive the first slider 411 and the head unit 41 to reciprocate horizontally along the first guide rail 421.

[0042] The packaging head 4 also includes a raw material storage tray 44, a wire feeding device 45, a counting device 46, a wire unwinding device 47, a wire winding device 48, and a twisting device 49.

[0043] The raw material storage plate 44, the wire feeding device 45, the counting device 46, the wire unwinding device 47, and the twisting device 49 are integrated and installed inside the head housing 41, while the wire winding device 48 is installed outside the head housing 41.

[0044] The raw material storage tray 44 is used to wind and store steel wire. The rotating shaft of the raw material storage tray 44 is a damping shaft, which can reduce the inertial force during the wire release process. Rotating the raw material storage tray 44 clockwise can release the steel wire, and rotating it counterclockwise can pull the steel wire back.

[0045] The wire feeding device 45 is installed downstream of the raw material storage tray 44, in the direction of wire exit, and is used to drive the wire forward. The wire feeding device 45 uses a double drive wheel conveyor to increase traction.

[0046] The counting device 46 is installed downstream of the wire feeding device 45 to record the length of the wire, thereby controlling the start and stop of the wire feeding device 45 and the wire unloading device 47.

[0047] The wire unwinding device 47 is installed above the raw material storage tray 44 and includes a friction disc 471, a wire unwinding motor 472, and a wire unwinding cylinder. The piston rod of the wire unwinding cylinder is connected to the friction disc 471 and is used to push the friction disc 471 to make tangential contact with the raw material storage tray 44. The wire unwinding motor 472 drives the friction disc 471 to rotate. The friction disc 471 drives the raw material storage tray 44 to rotate counterclockwise through friction, thereby realizing the wire unwinding function. The function of the wire unwinding function is to pull back and tighten the steel wire to make the binding more secure.

[0048] The wire winding device 48 is annular in shape, installed downstream of the counting device 46, and located outside the head housing 41. A clamp 481 is provided at the top of the wire winding device 48 to hold the end of the wire. After the wire enters the wire winding device 48, it winds around the inner ring at least once, and the end is clamped by the clamp 481. At this point, activating the wire unwinding device 47 can tighten the entire wire, making it adhere tightly to the outside of the gathered bar.

[0049] The knotting device 49 is installed directly above the winding device 48 and is used to cut the tightened steel wire and twist it into a knot with the end clamped by the clamp 481.

[0050] The working process of the baler head 4 is as follows: First, the first cylinder 412 pushes the head housing 41 to move horizontally towards the already gathered bar, so that the winding device 48 surrounds the outside of the bar; then the wire feeding device 45 is started, and the wire is fed out from the raw material storage tray 44, passes through the wire feeding device 45 and the counting device 46 in sequence, and enters the winding device 48. After winding around the ring at least once, the end is clamped by the clamp 481; the counting device 46 stops the wire feeding device 45 according to the recorded wire length and starts the wire unwinding device 47. At this time, the wire unwinding device 47 drives the raw material storage tray 44 to rotate counterclockwise, pulling the wire back and tightening it completely against the outside of the bar; after tightening, the knotting device 49 cuts the wire, and the two ends are twisted into a knot; finally, the first cylinder 412 pulls the head housing 41 back to reset, waiting to enter the next working cycle.

[0051] The baler base frame 2 is located directly below the frame 1 and is used to provide mounting points for the power unit 3, the fixed chain conveyor mechanism 5, the mobile chain conveyor mechanism 6, the transmission mechanism 7, the adjustment mechanism 8, the limit mechanism 9, and the positioning detection mechanism 10.

[0052] The fixed chain conveyor 5 and the mobile chain conveyor 6 are longitudinally opposite each other on the top of the baler base frame 2, and are used together for longitudinal conveying of the bar stock.

[0053] The fixed chain conveying mechanism 5 includes a fixed support frame 51, a guide groove 52, sprockets 53, a second cylinder 54, and a gathering device 55. The fixed support frame 51 is fixedly connected to the base frame 2 of the baler. Sprockets 53 are provided at both ends of the fixed support frame 51. The two sprockets 53 are connected by a ring chain. The rotation of the sprockets 53 drives the chain to move, conveying the bar stock longitudinally. The gathering device 55 is installed on the outer wall of the fixed support frame 51 and includes two claw arms. The two claw arms are hinged in the middle, forming a Y-shape. The lower parts of the two claw arms slide in the guide groove 52 and are connected to the piston rod of the second cylinder 54. The second cylinder 54 pushes the lower parts of the two claw arms to move vertically along the guide groove 52, thereby causing the gathering device 55 to open or close.

[0054] The mobile chain conveyor mechanism 6 includes a mobile support frame 61, a guide groove 52, sprockets 53, a second cylinder 54, and a gathering device 55. The mobile support frame 61 also has sprockets 53 at both ends, with chains connecting the sprockets 53, and a gathering device 55 installed on the side wall.

[0055] The difference is that the bottom of the movable support frame 61 is provided with a second slider 62, and two horizontal second guide rails 21 are provided on the base frame 2 of the baler. Through the sliding connection between the second slider 62 and the second guide rails 21, the movable chain conveyor mechanism 6 can slide horizontally and adjust its position to adapt to bars of different lengths.

[0056] In addition, the fixed chain conveyor 5 is a fixed end, and the position of the gathering device 55 on it is also fixed. The guide groove 52 and the second cylinder 54 that cooperate with the gathering device 55 can be directly fixed to the base frame 2 of the baler. However, the movable chain conveyor 6 is a movable end, and the position of the gathering device 55 on it moves with the movable chain conveyor 6. Consequently, the guide groove 52 and the second cylinder 54 that cooperate with the gathering device 55 also need to move with the movable support frame 61. Therefore, a follower bracket 63 is added to the movable support frame 61 as a mounting bracket for the guide groove 52 and the second cylinder 54 on the movable chain conveyor 6.

[0057] The transmission mechanism 7 is a horizontally arranged transmission shaft, which is mounted on the top of the baler base frame 2 via a bearing seat. The middle part of the transmission mechanism 7 is connected to the power unit 3 via a belt, and the two ends are respectively connected to the sprockets 53 on the fixed chain conveyor mechanism 5 and the mobile chain conveyor mechanism 6, so that the power unit 3 can drive the transmission mechanism 7 to rotate, thereby synchronously driving the fixed chain conveyor mechanism 5 and the mobile chain conveyor mechanism 6 to operate and longitudinally convey the bar material.

[0058] The adjustment mechanism 8 is used to drive the movable chain conveyor 6 to slide along the second guide rail 21 to accommodate bars of different lengths. The adjustment mechanism 8 includes a lead screw and a nut. The lead screw is horizontally arranged, passes through the movable chain conveyor 6, and is mounted on the baler base frame 2 through a bearing seat. The nut is fitted onto the lead screw and is fixedly connected to the movable chain conveyor 6. Rotating the lead screw can drive the movable chain conveyor 6 to slide horizontally along the second guide rail 21.

[0059] The limiting mechanism 9 is vertically mounted on the base frame 2 of the baler and is used to block and limit the bar stock. The limiting mechanism 9 includes a limiting rod 91 and a limiting cylinder 92. The limiting rod 91 is fixedly connected to the piston rod of the limiting cylinder 92. Both the limiting rod 91 and the limiting cylinder 92 are vertically arranged, and the limiting cylinder 92 can push the limiting rod 91 to rise and fall. When the limiting rod 91 rises, it blocks the bar stock at a designated position. The blocked bar stock accumulates and is gathered by the gathering device 55.

[0060] The positioning detection mechanism 10 is installed on the base frame 2 of the baler to detect in real time whether the bar material is gathered in place. When the bar material is gathered in place, it sends a signal to the baler head 4 to make the baler head 4 enter the working cycle.

[0061] The working principle of this invention is as follows: the power unit 3 drives the fixed chain conveyor 5 and the mobile chain conveyor 6 to operate synchronously through the transmission mechanism 7, and conveys the bars longitudinally; at the same time, the limiting mechanism 9 rises and blocks the bars at the limiting position, and the blocked bars are gathered by the gathering device 55; after the arrival detection mechanism 10 detects that a certain number of bars have been gathered in place, the baling head 4 starts; the first cylinder 412 pushes the head box 41 to move towards the gathered bars, and after reaching the designated position, it is bundled; after the bundling is completed, the head box 41, the gathering device 55, and the limiting mechanism 9 are reset, waiting to enter the next working cycle.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, equivalent changes, or alterations made by those skilled in the art using the disclosed technical content shall fall within the protection scope of the present invention.
