Abstract
Description
Technical Field
[0001] The utility model relates to a wire baling machine, in particular to a retaining mechanism for a baling wire of the wire baling machine. Background Art
[0002] Wire rod baling machine is a device used to pack wire rod coils after they are produced, in order to facilitate their later transportation and storage.
[0003] During the baling process of a wire baler, the baling wire is first wound around the wire coil through a threading channel and then tightened to achieve baling. As the baling head tightens the baling wire, it will break away from the original threading channel and quickly move toward the coil. During this rapid tightening process, the baling wire can easily deviate from its original position, a phenomenon known as "drifting." This prevents the baling wire from being tightly wrapped around the coil, causing the baled wire coil to become loose later, affecting transportation and storage. Summary of the Invention
[0004] The problem to be solved by the utility model is to provide a holding mechanism for the baling wire of a wire baling machine, which can assist in clamping the baling wire, thereby solving the problem of "deviation" of the baling wire during the baling process.
[0005] The utility model discloses a holding mechanism for a baling wire of a wire baling machine, which comprises two mirror-symmetrical holding units; each holding unit comprises a bracket, a swinging assembly, a spring assembly, and a fixing assembly; the bracket is a combination of an inclined upper part and a vertical lower part, one end of the swinging arm assembly is connected to the outer end of the vertical lower part of the bracket, and the other end is connected to a protruding block in the middle of the bracket through the spring assembly, and the fixing assembly is connected to the outer end of the inclined upper part of the bracket; the brackets of the two holding units form a bell mouth.
[0006] Furthermore, the swing assembly includes a swing arm, a protective block, and a fixed shaft. A groove is provided in the middle of the vertical lower outer end of the bracket, and the connecting part of the swing arm is located in the groove. The front and rear ends and the middle part of the fixed shaft respectively cooperate with the front and rear two holes of the bracket and the mounting hole of the swing arm connecting part. The protective block is provided with a mounting hole, and the screw passes through the mounting hole to fix it to the swing arm.
[0007] Furthermore, the swing assembly also includes two flange bushings, which are arranged between the front and rear holes of the bracket and the radial direction of the fixed shaft.
[0008] Furthermore, the swing assembly also includes a set screw, a radial screw hole is provided in the front hole or the rear hole of the bracket, an arc groove is provided at one end of the fixed shaft, and the set screw is tightened on the arc groove of the fixed shaft after being unscrewed from the screw hole of the bracket.
[0009] Further, the spring assembly includes a die spring, an adjusting block, a bolt, and a nut. The bolt passes through the central hole of the swing part of the swing arm and the die spring, and then is screwed into the adjusting block, the nut, and the threaded hole of the middle convex block of the bracket; the lower end of the adjusting block contacts the upper end of the die spring.
[0010] Further, the central hole of the swing part of the swing arm is a combination of an upper round hole and a lower waist-shaped hole.
[0011] Further, the spring assembly further includes a set screw. Threaded holes are provided on both sides of the middle convex block of the bracket, and the set screw is screwed into the threaded hole and then presses the bolt.
[0012] Further, the fixing assembly includes two front and rear mounts, two front and rear gasket groups, and a total of four connecting screws on the left and right in the front and rear; two left and right transition holes are provided at the front and rear of the outer end of the inclined upper part of the bracket, and the two left and right connecting screws pass through the flat washer, the transition hole, and the gasket group and then are connected to the threaded hole of the mounting block.
[0013] The working principle and advantages of the holding mechanism of the present utility model are as follows: The rapid wire retraction of the packing head causes the packing wire to quickly move away from the original wire threading channel and approach the coil. During the tensioning process of the packing wire, it will move towards the center under the guiding action of the flared openings formed by the brackets on both sides. When it touches the swing arm, it will exert a compression force on the die spring. Subsequently, the die spring, under the reaction force of compression, drives the swing arm to swing into the gap between the two holding units. In this way, after the wire retraction is in place, the packing wire is clamped at the designated position between the two protection blocks by the swing arms on both sides under the pressure of the die spring. Therefore, the holding mechanism of the present utility model can assist in clamping the packing wire, thereby solving the problem of "deviation" during the wire retraction and packing process of the packing wire. After the knotting is completed and the pressure plate resets, the packing wire is pulled out, and the device resets together with the pressure plate, waiting to enter the next packing cycle.

[0023] Embodiment 1
[0024] From Figure 1 , Figure 2 , Figure 3 , Figure 4 it can be seen that a holding mechanism for a packing wire of a wire packing machine of the present utility model includes two mirror-symmetrical holding units; each holding unit includes a bracket 1, a swing assembly, a spring assembly, and a fixing assembly; the bracket 1 is a combination of an inclined upper part and a vertical lower part, one end of the swing arm assembly is connected to the outer end of the vertical lower part of the bracket 1, and the other end is connected to the protruding block in the middle of the bracket 1 through the spring assembly, and the fixing assembly is connected to the outer end of the inclined upper part of the bracket 1; the brackets 1 of the two holding units form a flared opening.
[0025] The working principle and advantages of the holding mechanism of the present utility model are as follows: Each of the four wire channels of the packing head trolley of the horizontal wire packing machine is configured with a holding mechanism for the packing wire of the present utility model. When installing, the holding unit is welded to the pressure plates on both sides of the arc wire channel according to the actual working conditions. When the packing head quickly takes in the wire and the packing wire breaks away from the original wire threading channel and quickly approaches the coil, during the process of the packing wire being tightened, it will approach the center under the guiding action of the flared opening formed by the brackets 1 on both sides. When it touches the swing arm assembly, it will give a compression force to the die assembly. Then, under the reaction force of the compression, the die assembly will drive the swing arm assembly to swing into the gap between the two holding units. In this way, after the wire taking-in is in place, the packing wire is clamped in the middle of the swing arm assembly under the pressure of the die assembly. After the knotting is completed and the pressure plate returns to its original position, the packing wire is pulled out, and the holding mechanism returns to its original position together with the pressure plate, waiting to enter the next packing cycle. Therefore, the holding mechanism of the present utility model can assist in clamping the packing wire, thereby solving the problem of "running off track" during the process of taking in and packing the packing wire.
[0026] Embodiment 2
[0027] From Figure 1 , Figure 2 , Figure 3 , Figure 4It can be seen that the holding mechanism of the present utility model: the swinging assembly includes a swing arm 2, a protection block 5, and a fixed shaft 6. A groove is provided in the middle of the outer end of the vertical lower part of the bracket 1. The connecting part of the swing arm 2 is located in the groove. The front and rear ends and the middle part of the fixed shaft 6 are respectively fitted with the front and rear holes of the bracket 1 and the mounting holes of the connecting part of the swing arm 2. The protection block 5 is provided with mounting holes, and screws pass through the mounting holes and are fixedly connected to the swing arm 2.
[0028] The fixed shaft 6 connects the bracket 1 and the swing arm 2, and the swing arm 2 can freely rotate around the bracket 1 through the fixed shaft 6; the protection block 5 swings with the swing arm 2 and is in direct contact with the packing line and the coil, and a wear-resistant material is selected.
[0029] Embodiment 3
[0030] From Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 It can be seen that the holding mechanism of the present utility model: the swinging assembly further includes two flange bushings 4, and the flange bushings 4 are arranged radially between the front and rear holes of the bracket 1 and the fixed shaft 6.
[0031] The flange bushings 4 delay the wear between the fixed shaft 6 and the bracket 1 and extend the service life of the holding mechanism.
[0032] Embodiment 4
[0033] From Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 It can be seen that the holding mechanism of the present utility model: the swinging assembly further includes a set screw I 10. One of the front or rear holes of the bracket 1 is provided with a radial screw hole, and one end of the fixed shaft 6 is provided with an arc groove. The set screw I 10 is screwed out from the screw hole of the bracket 1 and pressed against the arc groove of the fixed shaft 6.
[0034] The set screw plays a positioning and fastening role for the fixed shaft 6, and further ensures that the swing arm 2 can freely rotate around the bracket 1 through the fixed shaft 6.
[0035] Embodiment 5
[0036] From Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 It can be seen that the holding mechanism of the present utility model: the spring assembly includes a die spring 7, an adjusting block 8, a bolt 11, and a nut 12. The bolt 11 passes through the central hole of the swinging part of the swing arm 2 and the die spring 7 and then is screwed together with the adjusting block 8, the nut 12, and the screw hole of the middle convex block of the bracket 1; the lower end of the adjusting block 8 is in contact with the upper end of the die spring 7.
[0037] The bolt 11 and the nut 12 realize the connection between the swinging part of the swing arm 2 and the middle convex block of the bracket 1; the adjusting block 8 moves up and down along the bolt through its screw hole to adjust the initial pressure of the die spring 7 according to actual needs, and further adjust the swinging amplitude of the swing arm 2. At the same time, by adjusting the pre-tightening force of the die springs 7 on both sides, the clamping force of the packing line can be set.
[0038] Embodiment 6
[0039] From Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 it can be seen that for the holding mechanism of the present utility model: the central hole of the swinging part of the swing arm 2 is a combination of an upper round hole and a lower waist-shaped hole.
[0040] The lower end face of the die spring 7 contacts the inner end face of the upper round hole of the swing arm 2, and a part of it is located inside the round hole, so the shaking of the die spring 7 is reduced, ensuring the reliability of the pressing of the adjusting block 8 on the die spring 7; the bolt 11 passes through the lower waist-shaped hole of the swing arm 2, ensuring the convenience of installation.
[0041] Embodiment 7
[0042] From Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 it can be seen that for the holding mechanism of the present utility model: the spring assembly further includes a set screw II 13, and screw holes are provided on both sides of the middle convex block of the bracket 1. After the set screw II 13 is screwed in from the screw hole, it presses the bolt 11.
[0043] After determining the pressing of the adjusting block 8 on the die spring 7, the bolt 11 can be pressed by the set screw II 13 to prevent it from loosening.
[0044] Embodiment 8
[0045] From Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 it can be seen that for the holding mechanism of the present utility model: the fixing assembly includes two front and rear mounting blocks 3, two front and rear gasket groups 9, and a total of four connecting screws 14 on the left and right in the front and rear; two left and right transition holes are provided at the front and rear of the outer end of the inclined upper part of the bracket 1, and the two left and right connecting screws 14 pass through the flat washers, transition holes, and gasket groups 9 and are connected to the screw holes of the mounting blocks 3.
[0046] The protection mechanism is welded to the pressure plate beside the wire path through the mounting block 3 to achieve the connection between the protection mechanism and the pressure plate. By changing the number of gaskets in the gasket group 9, the initial position of the holding mechanism (the position after the packing wire rewinding is completed), that is, the distance between the surface of the protection block 5 and the surface of the wear-resistant plate on the pressure plate, can be effectively adjusted. The gaskets in the gasket group 9 are preferably gaskets with U-shaped grooves to facilitate the quick addition or reduction of gaskets.
[0047] From Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 It can be seen that there are four wire paths on the trolley of the horizontal wire packing machine equipped with a packing head. Each wire path is configured with a holding mechanism for the packing wire of the present invention. When the holding unit is installed, it is welded to the pressure plates on both sides of the arc wire path after selecting the position according to the actual working conditions. The two holding units are mirror-symmetrical, and the flare formed by the two brackets 1 faces the arc wire path. Because in actual production, packing wires of different materials and different wire diameters may have different requirements for the clamping force, it is necessary to determine the initial distance between the two holding units, the magnitude of the clamping force, and the position after the packing wire rewinding is completed.
[0048] The working principle and advantages of the holding mechanism of the present invention are as follows: When the packing head quickly rewinds the wire, the packing wire breaks away from the original threading wire path and quickly approaches the coil. During the tensioning process of the packing wire, it will approach the center under the guiding action of the flare formed by the two brackets 1 on both sides. When it touches the swing arm 2, it will give a compression force to the die spring 7. Then, under the reaction force of the compression, the die spring 7 drives the swing arm 2 to swing into the gap between the two holding units. In this way, after the wire rewinding is in place, the packing wire is clamped at the specified position between the two protection blocks 5 by the two swing arms 2 under the pressure of the die spring 7. Therefore, the holding mechanism of the present invention can assist in clamping the packing wire, thus solving the problem of "deviation" during the packing wire rewinding and packing process. After the knot is tied and the pressure plate is reset, the packing wire is pulled out, and the device resets together with the pressure plate, waiting to enter the next packing cycle.
