Description

Technical Field

[0001] The invention belongs to the technical field of steel rolling production packaging and bundling, and in particular relates to a small bar wire bundling machine head and a working method. Background Art

[0002] The wire baler is a key device for cutting and tying wires such as metal wires and steel wires in the process of bar production. The existing technology mainly has the following technical defects:

[0003] (1) The mechanical structure is complex and costly

[0004] Similar equipment abroad mostly uses a purely mechanical transmission structure and requires a large number of precision-matched parts. This results in a bulky overall structure of the equipment, high requirements for component processing accuracy, and high assembly and maintenance costs.

[0005] (2) Multi-motor drive leads to increased energy consumption and failure rate

[0006] In the existing technology, wire feeding, cutting, twisting and other actions need to be configured with independent servo motor drives, resulting in high power consumption and complex control logic. Taking a typical foreign model as an example, its wire feeding, cutting and twisting mechanisms require more than three servo motors to work together, which not only increases the cost of the equipment, but also easily leads to problems such as wire breakage or loose bundling due to multi-motor synchronization errors.

[0007] (3) Low adjustment accuracy and poor adaptability

[0008] Traditional equipment uses a mechanical screw to adjust the tightness of wire feeding, which is difficult to achieve dynamic adjustment and cannot meet the packaging needs of materials with different wire diameters. When the wire diameter changes, it is necessary to stop the machine and manually adjust multiple adjustment bolts, resulting in reduced production efficiency.

[0009] (4) Inconvenient maintenance and low space utilization

[0010] Existing mechanical equipment uses an integral fixed base, and the transmission gear box, clutch and other components are arranged centrally, resulting in a closed internal space of the equipment, and a large number of covers need to be removed during maintenance.

[0011] (5) Insufficient automation

[0012] Traditional equipment relies on manual intervention to complete wire guiding and position calibration, which makes it difficult to achieve online monitoring and adaptive deviation correction. When the wire deflects, it is easy to cause kink angle deviation or cutter cutting position deviation. Summary of the invention

[0035] The working method of this small-sized bar wire channel packing machine head includes the following steps:

[0036] In the transmission system, the speed reducer changes the power of the main control servo motor to be perpendicular to the main control servo motor and transmits the power to the main transmission gear. The main transmission gear drives the electromagnetic clutch gears A and B to rotate, thereby respectively transmitting power to the wire feeding disc track wheel and the transmission bevel gear A; the wire feeding disc track wheel transmits power to the wire feeding device, and the transmission bevel gear A transmits power to the transmission bevel gear B, and the transmission bevel gear B transmits power to the kinking head in the rotary cutting mechanism;

[0037] When feeding wire, the wire feeding disc track wheel rotates clockwise, the electromagnetic brake A disengages, the electromagnetic clutch A engages, the electromagnetic brake B engages, the electromagnetic clutch B disengages, the track cylinder operates, opening the upper track and the lower track, and closing the track after the wire of the material to be packed enters the guide grooves of the upper track and the lower track. The wire biting cross connecting plate rotates to drive the wire biting cylinder to extend and retract. The wire biting cylinder restricts the wire feeding length and tightens the wire of the material to be packed; the wire feeding device and the wire guiding structure feed and guide the wire of the material to be packed: the starting end of the wire of the material to be packed passes through the central hole on one side of the kinking head, and the compression spring and the packing wire shaping steel balls cooperate to make the wire of the material to be packed enter the guide groove in the middle of the lower track, and transition along the guide groove in the middle of the lower track to the guide groove of the upper track. The wire of the material to be packed transitions again from the guide groove of the upper track to the guide groove of the front positioning block, and then from the guide groove of the upper track to the guide groove of the front positioning block again. The wire of the material to be packed then passes through the central hole on the other side of the kinking head along the guide groove of the front positioning block, forming a closed and crossed ring;

[0038] When kinking, bundling and cutting the wire of the material to be packed: the electromagnetic brake A engages, the electromagnetic clutch A disengages, the electromagnetic brake B disengages, the electromagnetic clutch B engages, the wire biting cross connecting plate rotates, and the wire biting cylinder operates; the transmission bevel gear A drives the transmission bevel gear B to rotate, and the kinking head rotates clockwise and combines with the wire biting cylinder to kink the wire of the material to be packed. At the same time of kinking, the cutter cuts the wire of the material to be packed with a set length when the kinking head rotates, so that the wire of the material to be packed is separated from the kinking head;

[0039] When taking in wire: the wire feeding disc track wheel rotates counterclockwise, the electromagnetic brake A disengages, the electromagnetic clutch A engages, the electromagnetic brake B engages, the electromagnetic clutch B disengages, and the wire biting cylinder is closed; the wire storage device temporarily stores the redundant wire of the material to be packed, straightens the wire of the material to be packed for the first time in the groove of the V-shaped wheel, and the wire pressing bearing prevents the wire of the material to be packed from slipping out of the groove and falling off. The wire of the material to be packed is straightened for the second time through the lower guide wheel in the groove of the wire pressing bearing;

[0040] When adjusting the tightness of the wire feeding device: twist the compression spring screw rod, and the deformation of the compression spring makes the tensioning slider slide in the sliding groove of the guiding block, adjusting the width of the sliding groove of the guiding block and thus adjusting the tightness of the wire of the material to be packed when passing through the sliding groove;

[0041] When performing maintenance on the small bar wire channel packing head, the cylinder pushes the packing head, and the sliding base enables the entire packing head to slide back and forth or slide at a set angle.

[0042] The beneficial effects of the present invention are:

[0043] The present invention uses a single motor drive to replace the multi-motor architecture in the prior art, and adopts a cooperative control scheme of a main control servo motor and an electromagnetic clutch; it simplifies the requirements for three independent motors of the traditional wire feeding, cutting knife, and kinking mechanisms into a single motor power source, simplifies the mechanical structure, reduces the equipment production cost, and significantly reduces energy consumption.

[0044] Through the rapid switching between electromagnetic clutches, the present invention can respond quickly and avoid the wire breakage problem caused by the errors between multiple motors; in the present invention, the electromagnetic clutch and the electromagnetic brake share the shaft system, which can reduce the usage amount of the transmission shaft, significantly reduce the total number of parts compared with similar models, reduce the failure rate while reducing energy consumption, and can also significantly improve the transmission efficiency.

[0045] The sliding base of the present invention realizes the overall displacement adjustment through linear guide rails, which is convenient for maintenance, and also significantly reduces the size of the equipment in the axial direction, with high space utilization rate. The present invention also sets up quick-disassembly structures such as maintenance pins and cylinder push seats, which significantly shortens the maintenance time.

[0046] The present invention can complete all functions such as wire channel closing and opening, wire feeding, wire biting, wire collecting, wire shearing, and kinking with a main control servo motor, a reducer, a wire biting cylinder, and a wire channel cylinder, effectively improving the degree of automation; the present invention can complete the entire packing cycle within 3 to 5 seconds.

[0047] The present invention makes the compression spring deform by twisting the compression spring screw, and then makes the tensioning slider slide in the chute of the guide block, adjusts the width of the chute of the guide block, and further adjusts the tightness when the material wire to be packed passes through the chute, which can realize dynamic adjustment and meet the packing requirements of materials with different wire diameters.

[0048] In summary, the small bar wire channel packing head designed by the present invention has a short packing cycle, fast packing speed, low manufacturing cost, and stable and reliable operation. Description of the Drawings

[0099] Embodiment 2

[0100] Based on Embodiment 1, the working method of the small bar wire channel packing head includes the following steps:

[0101] In the transmission system 200, the speed reducer 202 changes the power of the main control servo motor 201 to be perpendicular to the main control servo motor 201 and transmits this power to the main transmission gear 214. The main transmission gear 214 drives the electromagnetic clutch gear A 205 and the electromagnetic clutch gear B 212 to rotate, thereby respectively transmitting to the wire feeding disc wire channel wheel 001 and the transmission bevel gear A 210; the wire feeding disc wire channel wheel 001 transmits to the wire feeding device 400, the transmission bevel gear A 210 transmits to the transmission bevel gear B 110, and the transmission bevel gear B 110 transmits to the kinking head 002 in the rotary cutting mechanism 100;

[0102] When feeding wire, the wire feeding disc wire channel wheel 001 rotates clockwise, the electromagnetic brake A 003 disengages, the electromagnetic clutch A 004 engages, the electromagnetic brake B 005 engages, the electromagnetic clutch B 006 disengages, the wire channel cylinder 305 acts, opening the upper wire channel 306 and the lower wire channel 307. After the material wire to be packed enters the guide grooves of the upper wire channel 306 and the lower wire channel 307, the wire channels are closed. The wire biting horizontal connecting plate 007 rotates to drive the wire biting cylinder 106 to expand and contract. The wire biting cylinder 106 restricts the wire feeding length and tightens the material wire to be packed; the wire feeding device 400 and the wire guiding structure 300 feed and guide the material wire to be packed: the starting end of the material wire to be packed passes through the central hole on one side of the kinking head 002. The compression spring 404 and the packing wire shaping steel balls cooperate to make the material wire to be packed enter the guide groove in the middle of the lower wire channel 307 and transition along the guide groove in the middle of the lower wire channel 307 to the guide groove of the upper wire channel 306. The material wire to be packed then transitions from the guide groove of the upper wire channel 306 to the guide groove of the front in-place block 311 again. The material wire to be packed then transitions from the guide groove of the upper wire channel 306 to the guide groove of the front in-place block 311 again, and then the material wire to be packed passes through the central hole on the other side of the kinking head 002 along the guide groove of the front in-place block 311, forming a closed and crossed ring;

[0103] When kinking, bundling and cutting the material line to be packed: electromagnetic brake A003 engages, electromagnetic clutch A004 disengages, electromagnetic brake B005 disengages, electromagnetic clutch B006 engages, the wire-biting cross connecting plate 007 rotates, and the wire-biting cylinder 106 operates; the driving bevel gear A210 drives the driving bevel gear B110 to rotate, and the kinking head 002 rotates clockwise to cooperate with the wire-biting cylinder 106 to kink the material line to be packed. At the same time of kinking, the cutter 303 cuts the material line to be packed with a set length when the kinking head 002 rotates, so that the material line to be packed is separated from the kinking head 002;

[0104] When taking in wire: the wire guiding wheel 001 of the wire feeding disk rotates in the counterclockwise direction, electromagnetic brake A003 disengages, electromagnetic clutch A004 engages, electromagnetic brake B005 engages, electromagnetic clutch B006 disengages, and the wire-biting cylinder 106 is closed; the wire storage device 600 temporarily stores the redundant material line to be packed, and straightens the material line to be packed 609 for the first time in the groove of the V-shaped wheel 601. The wire pressing bearing 602 prevents the material line to be packed 609 from slipping out of the groove and falling off. The material line to be packed 609 is straightened for the second time in the groove of the wire pressing bearing through the lower guide wheel 604;

[0105] When adjusting the tightness of the wire feeding device 400: twist the compression spring screw 401, and the deformation of the compression spring 404 causes the tensioning slider 413 to slide in the chute of the guide block 419, so as to adjust the width of the chute of the guide block 419 and further adjust the tightness of the material line to be packed when passing through the chute;

[0106] When overhauling and maintaining the small bar wire channel packing head, the cylinder 511 pushes the packing head, and the sliding base 500 makes the whole packing head slide back and forth, or makes the whole packing head slide at a set angle.
