Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production of bed net frames, in particular to a wire feeding and correcting mechanism and a bed net frame production line. Background Art
[0002] At present, for the production of the steel wire frame of a mattress, first, the steel wire needs to be straightened and then cut according to production requirements. Workers place the cut steel wire on a bending device and bend the steel wire into a square shape according to product requirements. Finally, the connection points of the steel wire are placed on a welding machine for welding to finally form the required bed net frame.
[0003] Manual handling for wire feeding cannot accurately determine the length of the initial bending section at the end of the steel wire, which results in the situation that when the steel wire is bent by a bending machine, the connection points cannot be aligned with the sleeves of the welding machine and clamped and fixed. Therefore, a wire feeding and correcting mechanism is needed to solve the above problems. Summary of the Utility Model
[0004] To overcome the above disadvantages, the purpose of the utility model is to provide a wire feeding and correcting mechanism and a bed net frame production line, which can automatically and accurately correct the length of the initial bending section at the end of the steel wire, ensure that the two ends of the steel wire can be normally sleeved and fixed after bending, and improve the production efficiency of the bed net frame.
[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a wire feeding and correcting mechanism for transferring the steel wire straightened by a feeding and straightening mechanism and cut by a steel wire cutting mechanism to a bending mechanism for bending, including a horizontally arranged steel wire threading support; a correcting mechanism is arranged below the steel wire threading support along its length direction, and the correcting mechanism includes a displacement component capable of adjusting the horizontal displacement of the steel wire. The displacement component includes a clamping component and a driving component. The clamping component can clamp one end of the cut steel wire and move back and forth horizontally under the driving action of the driving component.
[0006] Furthermore, a plurality of guiding and feeding components are arranged at intervals along the steel wire threading direction on the steel wire threading support. The guiding and feeding components include a guiding member and a limiting member. A limiting space for the steel wire to pass through from top to bottom is left between the guiding member and the limiting member. The cut steel wire can fall to the correcting mechanism through the guiding of the guiding member. The guiding and feeding components can provide guiding for the falling of the cut steel wire and avoid the position deviation during falling from affecting the subsequent size correction.
[0007] Further, the guiding member and the limiting member are arranged on both sides of the steel wire threading bracket in the vertical direction. The guiding member includes a connecting section, a guiding inclined side, a guiding vertical side, and a supporting horizontal side that are sequentially connected. One end where the guiding inclined side is connected to the guiding vertical side is inclined towards the limiting member. A displacement channel for the horizontal removal of the steel wire from the guiding and feeding assembly is left between the supporting horizontal side and the bottom end of the limiting member. The supporting horizontal side corresponds to the clamping assembly in position. The supporting horizontal side can provide support for the steel wire that has fallen along the guiding member, so that the steel wire remains horizontal after falling, facilitating subsequent wire feeding operations;
[0008] By setting the supporting horizontal side to correspond to the clamping assembly in position, the steel wire clamped by the clamping assembly is in a horizontal state, facilitating the feeding of the steel wire to the bending mechanism;
[0009] The inclined guiding inclined side can provide a buffering effect for the falling of the steel wire, avoiding damage to the lower calibration mechanism caused by the falling of the steel wire under the action of its gravity.
[0010] Further, it further includes a steel wire support frame. The steel wire support frame includes a cross bar arranged parallel to the steel wire threading bracket. A plurality of support frames are arranged on the cross bar along its length direction. The support frame includes a horizontally arranged placing edge. The placing edge is located below the steel wire threading bracket and is arranged towards the guiding member.
[0011] After the steel wire is cut by the steel wire cutting mechanism, it will first fall onto the support frame. The placing edge plays a supporting role for the steel wire. Compared with the steel wire directly falling from the steel wire threading bracket to the lower calibration mechanism below, in this application, the placing edge provides a buffering effect for the falling of the steel wire in advance, and the steel wire is more stable when moving from the placing edge to the guiding and feeding assembly and falling.
[0012] Further, a limiting channel for the steel wire to pass through is left between the end of the placing edge and the connecting section. Ensure that after the steel wire leaves the placing edge, it can abut against the inner wall of the guiding member and slide closely along the inner wall of the guiding member until it falls on the supporting horizontal side.
[0013] Further, the calibration mechanism includes a calibration bracket and a displacement bracket. The displacement bracket is connected to the calibration bracket through a horizontally arranged installation support plate. The clamping assembly is arranged on the displacement bracket and can move back and forth along the guiding slide rod on the displacement bracket under the action of the driving assembly. The displacement bracket plays a supporting role for the setting of the clamping assembly, and the guiding slide rod can provide guidance for the movement of the clamping assembly, enabling it to accurately feed the steel wire to the bending position for bending.
[0014] Further, the clamping assembly is a pneumatic gripper. A steel wire support plate is arranged on one side of the pneumatic gripper close to the feeding and straightening mechanism. The top of the steel wire support plate abuts against the lower part of the steel wire clamped by the pneumatic gripper. The steel wire support plate is horizontally arranged. When the steel wire falls onto the support cross edge under the guiding action of the guiding and discharging assembly, the steel wire support plate can provide an upward supporting force for the steel wire, supporting the part not supported by the support cross edge thereon, avoiding the bending of the steel wire, and ensuring the stability of the pneumatic gripper clamping the steel wire and feeding the wire.
[0015] It should be noted that the clamping assembly is not limited to being a pneumatic gripper, as long as it can clamp one end of the steel wire.
[0016] Further, the driving assembly is a belt drive assembly. The belt drive assembly includes a vertically arranged driving motor, two transmission gears, and a belt. One side of the belt is fixedly connected to the clamping assembly through a connecting plate. The driving motor drives the transmission gears to rotate, so that the belt can drive the clamping assembly thereon to move back and forth along the guiding slide rod to adjust the length of the initial bending section of the steel wire.
[0017] Further, a butting plate corresponding to the position of the clamping assembly is arranged on the installation support plate. After one end of the steel wire abuts against the butting plate, the measured size value of the steel wire can be made more accurate.
[0018] A bed net frame production line includes a wire feeding and straightening mechanism.
[0019] Advantages of the present utility model:
[0020] In the present utility model, the displacement assembly can move back and forth under the driving action of the driving assembly, and thus can adjust the position of the steel wire in the horizontal direction relative to the external bending mechanism, and automatically adjust the length of the initial bending section of the steel wire to ensure that the lengths of both ends of the steel wire can be normally sleeved and fixed after bending, effectively improving the production efficiency of the bed net frame.

[0026] The following elaborates on the preferred embodiments of the present utility model in conjunction with the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.
[0027] See the attached Figures 1 to 4 As shown, a wire feeding and straightening mechanism in this embodiment is used to transfer the steel wire straightened by the loading and straightening mechanism 1 and cut by the steel wire cutting mechanism 2 to the bending mechanism for bending. The loading and straightening mechanism 1 is used to straighten the steel wire coiled on the wire rack, and the steel wire cutting mechanism 2 automatically cuts the steel wire into the length required for the bed net frame. It should be noted that the above loading and straightening mechanism 1 and steel wire cutting mechanism 2 are both prior arts, and their structures will not be elaborated here too much;
[0028] It includes a horizontally arranged steel wire threading bracket 3; a straightening mechanism 6 is arranged below the steel wire threading bracket 3 along its length direction. The straightening mechanism 6 includes a displacement assembly 63 capable of adjusting the horizontal displacement of the steel wire. The displacement assembly 63 includes a clamping assembly 633 and a driving assembly. The clamping assembly 633 can clamp one end of the cut steel wire and move back and forth horizontally under the driving action of the driving assembly. The displacement assembly 63 can move back and forth under the driving action of the driving assembly, and thus can adjust the position of the steel wire in the horizontal direction relative to the external bending mechanism, and automatically adjust the length of the initial bending section of the steel wire to ensure that the lengths of both ends of the steel wire can be normally sleeved and fixed after bending, effectively improving the production efficiency of the bed net frame.
[0029] In some embodiments, an open steel wire groove is formed at the bottom of the steel wire threading bracket 3, so that the steel wire can fall downward to the straightening mechanism 6 below after being cut.
[0030] A plurality of guiding and feeding components 5 are arranged on the steel wire threading bracket 3 at intervals along the steel wire threading direction. The guiding and feeding component 5 includes a guiding member 52 and a limiting member 51. A limiting space for the steel wire to pass through from top to bottom is left between the guiding member 52 and the limiting member 51. The cut steel wire can fall to the calibration mechanism 6 through the guiding of the guiding member 52. The guiding and feeding component 5 can guide the falling of the cut steel wire to prevent the position deviation during falling from affecting the subsequent size calibration.
[0031] The guiding member 52 and the limiting member 51 are arranged on both sides of the steel wire threading bracket 3 in the vertical direction. The guiding member 52 includes a connecting section, a guiding inclined side 521, a guiding vertical side 522, and a supporting horizontal side 523 which are connected in sequence. One end where the guiding inclined side 521 is connected to the guiding vertical side 522 is inclined towards the direction of the limiting member 51. A displacement channel for the steel wire to horizontally move out of the guiding and feeding component 5 is left between the supporting horizontal side 523 and the bottom end of the limiting member 51. The supporting horizontal side 523 corresponds to the position of the clamping component 633. The supporting horizontal side 523 can support the steel wire falling along the guiding member 52, so that the steel wire is always in a horizontal state after falling, which is convenient for the subsequent wire feeding operation;
[0032] By setting the supporting horizontal side 523 to correspond to the position of the clamping component 633, the steel wire clamped by the clamping component 633 is in a horizontal state, which is convenient for feeding it to the bending mechanism;
[0033] The inclined guiding inclined side 521 can provide a buffering effect for the falling of the steel wire to prevent the steel wire from damaging the lower calibration mechanism 6 after falling under the action of its gravity.
[0034] In some embodiments, the distance between the limiting member 51 and the guiding vertical side 522 is less than the distance between the connecting section and the guiding vertical side 522, so that the steel wire can obtain a better guiding effect when falling from top to bottom. The setting of the limiting member 51 can also prevent the steel wire from deviating from the range where the clamping component 633 can clamp the steel wire during falling, avoiding affecting the subsequent wire feeding operation.
[0035] It further includes a steel wire support frame 4. The steel wire support frame 4 includes a cross bar 41 arranged parallel to the steel wire threading bracket 3. A plurality of support frames 42 are arranged on the cross bar 41 along its length direction. The support frame 42 includes a horizontally arranged placing edge 43. The placing edge 43 is located below the steel wire threading bracket 3 and is arranged towards the direction of the guiding member 52.
[0036] After being cut by the steel wire cutting mechanism 2, the steel wire will fall onto the support frame 42 in advance. The placement edge 43 supports the steel wire. Compared with the steel wire directly falling from the steel wire threading bracket 3 to the lower calibration mechanism 6 below, in this application, the placement edge 43 buffers the falling of the steel wire in advance, and the steel wire is more stable when moving and falling from the placement edge 43 to the guiding and feeding component 5.
[0037] Specifically, the distance between the placement edge 43 and the lower surface of the steel wire threading bracket 3 is just enough for a steel wire to move back and forth. When the distance is too large, the steel wire is likely to fall and deviate from the placement edge 43 and directly pass through the guiding and feeding component 5 and fall onto the calibration mechanism 6. When the distance is too small, the steel wire cannot move out of this space.
[0038] In some embodiments, the support frame 42 is arranged in an L shape. Its vertically arranged side is used to fix the support frame 42 on the cross bar 41, and the horizontally arranged side is the placement edge 43 that can support the steel wire.
[0039] Regarding the setting of the cross bar 41, in some embodiments, under the action of an external force, the cross bar 41 drives the placement edge 43 to rotate in a direction away from the guiding and feeding component 5, so that the steel wire placed on the placement edge 43 slides along the inclined placement edge 43 until it abuts against the guiding member 52 and slides down along the inner side of the guiding member 52 until it falls into the calibration mechanism 6.
[0040] In some other embodiments, the cross bar 41 does not rotate. The steel wire on the placement edge 43 can be pushed by the staff in the direction of the guiding and feeding component 5, so that the steel wire can be close to the guiding member 52 and fall along the guiding member 52 to the calibration mechanism 6 for subsequent length calibration.
[0041] A limiting channel for the steel wire to pass through is left between the end of the placement edge 43 and the connecting section. Ensure that after the steel wire leaves the placement edge 43, it can abut against the inner wall of the guiding member 52 and slide closely along the inner wall of the guiding member 52 until it falls on the supporting cross edge 523.
[0042] The calibration mechanism 6 includes a calibration bracket 61 and a displacement bracket 632. The displacement bracket 632 is connected to the calibration bracket 61 through a horizontally arranged installation support plate 62. The clamping component 633 is arranged on the displacement bracket 632 and can move back and forth along the guiding slide rod on the displacement bracket 632 under the action of the driving component. The displacement bracket 632 supports the setting of the clamping component 633, and the guiding slide rod can provide guidance for the movement of the clamping component 633, so that it can accurately send the steel wire to the bending position for bending.
[0043] The clamping assembly 633 is a pneumatic gripper. On one side of the pneumatic gripper close to the feeding and straightening mechanism 1, there is a steel wire support plate 634. The top of the steel wire support plate 634 abuts against the lower part of the steel wire clamped by the pneumatic gripper. The steel wire support plate 634 is horizontally arranged. When the steel wire falls onto the support horizontal edge 523 under the guiding action of the guiding and discharging assembly 5, the steel wire support plate 634 can provide an upward supporting force for the steel wire, support the part not supported by the support horizontal edge 523 thereon, prevent the steel wire from bending, and ensure the stability of the pneumatic gripper clamping the steel wire and feeding the wire.
[0044] It should be noted that the clamping assembly 633 is not limited to being a pneumatic gripper, as long as it can clamp one end of the steel wire.
[0045] The driving assembly is a belt drive assembly 631. The belt drive assembly 631 includes a vertically arranged driving motor, two transmission gears and a belt. One side of the belt is fixedly connected to the clamping assembly 633 through a connecting plate. The driving motor drives the transmission gears to rotate, so that the belt can drive the clamping assembly 633 thereon to move back and forth along the guiding slide rod to adjust the length of the initial bending section of the steel wire.
[0046] On the mounting support plate 62, there is a butting plate 64 corresponding to the position of the clamping assembly 633. After one end of the steel wire abuts against the butting plate 64, the measured dimension value of the steel wire can be made more accurate.
[0047] A bed net border production line includes a wire feeding and straightening mechanism.

Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
