Description

Technical Field

[0001] The invention belongs to the field of steel wire production equipment and relates to a reel-assisted wire pushing device for an elephant trunk wire unloading machine. Background Art

[0002] In the production of steel wire, the finished steel wire drawn by the wire drawing machine is rotated and pulled by a set of guide wheels and a turntable on the elephant trunk wire unloading machine, so that the steel wire is continuously wound on the reel of the elephant trunk wire unloading machine, and the steel wire at the rear end of the reel continuously pushes the front end steel wire to slide through the elephant trunk frame and into the flower fence frame, thereby realizing large-scale non-stop wire unloading; currently when winding low-carbon small-specification steel wire, such as low-carbon steel wire with a diameter of 0.6mm, due to the resilience of the steel wire itself, the sliding resistance of the steel wire wound on the reel at the root of the elephant trunk becomes larger, so that the rear end steel wire cannot push the front end steel wire, which is easy to cause wire clamping and wire breakage. Once the steel wire is clamped or broken, it is necessary to stop the machine in time to solve the problem, which seriously reduces the production efficiency. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a wire-pushing device for a reel of an elephant-trunk wire unloading machine.

[0004] The present invention is achieved through the following technical solutions.

[0005] The present invention provides a wire-pushing device for an elephant-trunk wire unloading machine drum, which comprises a swing bracket, a pulley A, a pulley B, a wire-pushing belt, and a power mechanism. The pulley A and the pulley B are installed on the swing bracket for colinear rotation at intervals. For example, the pulley A and the pulley B are fixedly matched with the roller outer ring of the bolt roller bearing, and the bolt end of the bolt roller bearing is fixedly installed on the swing bracket; the wire-pushing belt is installed on the pulley A and the pulley B, and the power mechanism is connected to the pulley A or the pulley B. The power mechanism is, for example, just a shaking hand lever, and the shaking hand lever is connected to the outer end face of the pulley A or the pulley B, so that the pulley A or the pulley B can be manually shaken to rotate.

[0006] The swing bracket is firmly and stably fixed on the equipment frame by a bolt assembly or a support frame is made as needed, so that the pulley C is parallel to the generatrix of the outer edge of the drum. The push belt presses the steel wire when being tightened by pulleys A and B. The power mechanism drives pulley A or pulley B to rotate, so that the steel wire at the rear end of the winding drum is smoothly pushed to the rear end of the winding drum and the rear push trunk is pushed with the assistance of the push belt, which solves the problem that the steel wire wound on the rear end of the drum cannot push away the front end steel wire, avoids the phenomenon of wire clamping and wire breakage, and improves production efficiency.

[0007] Pulley A and pulley B can be V-pulleys, preferably flat pulleys, so that the push belt runs more smoothly, the contact area with the steel wire is increased, and the auxiliary force on the steel wire is increased.

[0008] In order to facilitate the control of the power mechanism and meet the requirements of automated production, the power mechanism is a vertical output reduction motor, such as the reduction F1 series motor of Haoli Company.

[0009] The preferred power mechanism and the pulley A and the pulley B are installed on different planes of the swing bracket, thereby avoiding motion interference and improving visualization during production and maintenance.

[0010] It also includes a guide block, which is fixedly installed on a swing bracket between pulleys A and B through a bolt assembly. The bottom edge of the guide block is in line with the bottom tangent points of pulley A and pulley B and is in contact with the push belt. When the push belt is running, due to the long interval between pulleys A and B, the push belt is loose after it turns out from pulley B. Since the loose edge of the push belt will self-contract, after long-term operation, the contact between the push belt and the steel wire is not full contact. The guide block turns the loose edge of the push belt into a tight edge, so that the push belt and the steel wire are always in full contact, thereby improving the pushing stability of the push belt on the steel wire.

[0011] The installation position between the guide block and the pulley B is such that the interval between the two is greater than 0 and less than the radius of the steel wire, so that the normal operation of the guide block is ensured while the contact surface between the push belt and the steel wire is increased under the action of the guide block, so that the push belt can better push the steel wire forward.

[0012] The guide block is a flat plate, and the contact surface between the guide block and the push wire is a plane, which is easy to install, reduces the volume, and facilitates better contact between the guide block and the push wire, thereby improving the guiding performance of the guide block on the movement of the steel wire.

[0013] The invention also includes a pulley C, which is rotatably fixedly installed on the swing bracket. The pulley C is coplanar with the pulleys A and B and is distributed in a triangle, so that the push belt is subjected to more uniform force when the pulleys C, A and B rotate, and the push belt guides the steel wire more stably. The turnover length of the push belt is longer and the turning angle is larger, thereby improving the service life of the push belt.

[0014] At this time, the output shaft of the vertical output reduction motor is fixedly connected to the pulley C using a coupling, and the vertical output reduction motor drives the pulley C to rotate.

[0015] The pulley C forms a right triangle with the pulleys A and B. The corresponding angles of the pulleys A and B are right angles, and the corresponding angles of the pulleys B and C are 55° to 63°, so that the push belt obtains better tension.

[0016] It also includes a mounting bracket and multiple connecting rods. The mounting bracket is hinged to the swing bracket via the multiple connecting rods. The swing bracket can swing up and down on the mounting bracket to facilitate the inspection and maintenance of the swing bracket and the components fixed thereon, and to facilitate the replacement, position adjustment and maintenance of the steel wire. The components of all equipment on the swing bracket will ensure that the push belt is in stable contact with the steel wire.

[0017] The two connecting rods connecting the mounting bracket and the swing bracket are rotatably connected by a pin shaft on the body, which improves the connection firmness between the swing bracket and the mounting bracket, avoids the small vibration generated by the power mechanism from being resonated and amplified on the swing bracket, and improves the stability of equipment operation.

[0018] An operating handle is fixed on the swing bracket to facilitate the up and down rotation of the swing bracket and the mounting bracket.

[0019] The operating handle is hinged to the mounting bracket, with the mounting bracket as the force point, so that the swing bracket can be raised and lowered more effortlessly; the middle part of the operating handle is installed in a sleeve fixed on the swing bracket, which facilitates the disassembly of the operating handle and the mounting bracket.

[0020] The operating handle is installed on the mounting bracket on the same side as the power mechanism. Since the power mechanism accounts for a large proportion of the overall weight, in order to reduce the overall weight, the size of the mounting bracket is as small as possible. When the mounting bracket is lifted and lowered, the fixed point of the operating handle on the mounting bracket and the power mechanism will not generate torque, thereby avoiding deformation of the mounting bracket that affects the change in the position of the push belt, thereby ensuring the stability of the contact between the push belt and the steel wire.

[0021] The beneficial effects of the present invention are as follows: the vertical output reduction motor drives the pulley C to rotate, the pulley C drives the push-belt belt to operate, the guide block makes the push-belt belt tightly contact and fit with the steel wire, the steel wire assists the push-belt belt to be pushed forward smoothly, the front and rear end steel wires on the reel are smoothly pushed off the reel to the trunk to complete the unloading, avoiding the phenomenon of wire clamping and wire breakage, and improving production efficiency.

[0027] The technical solution of the present invention is further described below, but the scope of protection claimed is not limited to the description.

[0028] like Figure 1-4 shown.

[0029] The present invention discloses a wire-pushing device for a wire-unloading machine with an elephant trunk, which comprises a swing bracket 1, a pulley A2, a pulley B3, a wire-pushing belt 4, and a power mechanism. The pulleys A2 and B3 are installed on the swing bracket 1 for colinear rotation at intervals. For example, the pulleys A2 and B3 are fixedly matched with the roller outer rings of the bolt roller bearings, and the bolt ends of the bolt roller bearings are fixedly installed on the swing bracket 1; the wire-pushing belt 4 is installed on the pulleys A2 and B3, and the power mechanism is connected to the pulleys A2 or B3. The power mechanism is, for example, just a shaking hand lever, and the shaking hand lever is connected to the outer end face of the pulleys A2 or B3, so that the pulleys A2 or B3 can be driven to rotate by manual shaking.

[0030] The push belt 4 is tightened by the pulley A2 and the pulley B3 to press the steel wire 14, and the power mechanism drives the pulley A2 or the pulley B3 to rotate, so that the steel wire 14 at the front end of the winding drum 11 is smoothly pushed to the trunk 12 with the assistance of the push belt 4, which solves the problem that the steel wire 14 wound at the rear end of the drum 11 cannot push the front end steel wire 14 away, avoids the phenomenon of wire clamping and wire breakage of the steel wire 14, ensures the smooth movement of the steel wire 14 from the drum 11 to the trunk 12, and improves production efficiency.

[0031] The pulley A2 and the pulley B3 can be V-pulleys, preferably flat pulleys, so that the push belt 4 can run more smoothly, increase the contact area with the steel wire 14, and increase the auxiliary force on the steel wire 14.

[0032] In order to facilitate the control of the power mechanism and meet the requirements of automated production, the power mechanism is a vertical output reduction motor, such as the reduction F1 series motor of Haoli Company.

[0033] The preferred power mechanism and the pulleys A2 and B3 are installed on different planes of the swing bracket 1, thereby avoiding motion interference and improving visualization during production and maintenance.

[0034] The guide block 5 is also included. The guide block 5 is fixedly installed on the swing bracket 1 between the pulley A2 and the pulley B3 through a bolt assembly. The bottom edge line of the guide block 5 is in line with the bottom tangent point of the pulley A2 and the bottom tangent point of the pulley B3 and is in contact with the push belt 4. When the push belt 4 is running, due to the long interval between the pulley A2 and the pulley B3, the push belt 4 is a loose edge after it is turned out from the pulley B3. Since the loose edge of the push belt 4 will self-contract, after long-term operation, the contact between the push belt 4 and the steel wire 14 is not full contact. The guide block 5 turns the loose edge of the push belt 4 into a tight edge, so that the push belt 4 and the steel wire 14 are always in full contact, thereby improving the pushing stability of the push belt 4 on the steel wire 14

[0035] The installation position between the guide block 5 and the pulley B3 is such that the interval between the two is greater than 0 and less than the radius of the steel wire, so that the normal operation of the guide block 5 is ensured. At the same time, the contact surface between the push belt 4 and the steel wire 14 is increased under the action of the guide block 5, so that the push belt 4 can better push the steel wire 14 forward.

[0036] The guide block 5 is a flat plate, and the contact surface between the guide block 5 and the push belt 4 is a plane, which is easy to install, reduces the volume, and facilitates better contact between the guide block 5 and the push belt 4, thereby improving the guiding performance of the guide block 5 on the movement of the steel wire 14.

[0037] The invention also includes a pulley C6, which is rotatably fixedly installed on the swing bracket 1. The pulley C6 is coplanar with the pulleys A2 and B3 and distributed in a triangle, so that the push belt 4 is subjected to more uniform force when rotating under the action of the pulleys C6, A2 and B3, and the guide of the push belt 4 to the steel wire 14 is more stable. The turnover length and angle of the push belt 4 are increased, thereby improving the service life of the push belt 4.

[0038] At this time, the output shaft of the vertical output reduction motor is fixedly connected to the pulley C6 using a coupling, and the vertical output reduction motor drives the pulley C6 to rotate.

[0039] The pulley C6 forms a right triangle with the pulleys A2 and B3. The corresponding angles between the pulleys A2 and B3 are right angles, and the corresponding angles between the pulleys B3 and C6 are 55° to 63°, so that the push belt 4 obtains better tension.

[0040] It also includes a mounting bracket 7 and multiple connecting rods 8. The mounting bracket 7 is hinged to the swing bracket 1 via multiple connecting rods 8 to form at least a four-sided connecting rod. The swing bracket 1 can swing up and down on the mounting bracket 7 to facilitate the inspection and maintenance of the swing bracket 1 and the components fixed thereon, and at the same time facilitate the replacement, position adjustment and inspection of the steel wire 14. The weight of all the components on the swing bracket 1 will ensure that the push wire 4 is stably in contact with the steel wire 14.

[0041] The two connecting rods 8 connecting the mounting bracket 7 and the swing bracket 1 are rotatably connected by the pin shaft 10, which improves the connection firmness between the swing bracket 1 and the mounting bracket 7, avoids the small vibration generated by the power mechanism from being resonated and amplified on the swing bracket 1, and improves the stability of equipment operation.

[0042] An operating handle 9 is fixed on the swing bracket 1 to facilitate the upward and downward rotation of the swing bracket 1 and the mounting bracket 7 .

[0043] The operating handle 9 is hinged to the mounting bracket 7, with the mounting bracket 7 as the force point, so that the swing bracket 1 can be raised and lowered more effortlessly; the middle part of the operating handle 9 is installed in a sleeve fixed on the swing bracket 1, which is convenient for disassembly of the operating handle 9 and the mounting bracket 7.

[0044] The operating handle 9 is installed on the mounting bracket 7 on the same side as the power mechanism. Since the power mechanism accounts for a large proportion of the overall weight, in order to reduce the overall weight, the size of the mounting bracket 7 is as small as possible. When the mounting bracket 7 is lifted and lowered, the fixed point of the operating handle 9 on the mounting bracket 7 and the power mechanism will not generate torque, thereby avoiding deformation of the mounting bracket 7 that affects the change in the position of the push belt 4, thereby ensuring the stability of the contact between the push belt 4 and the steel wire 14.

[0045] Working principle: The swing bracket 1 is firmly and stably fixed to the equipment frame 13 through a bolt assembly or a support frame is made as needed, so that the pulley C6 is parallel to the busbar of the outer edge of the reel 11, and the vertical output reduction motor drives the pulley C6 to rotate, and the pulley C6 drives the push belt 4 to operate. The guide block 5 makes the push belt 4 and the steel wire 14 tightly contact and fit. With the assistance of the push belt 4 and the smooth forward thrust, the front and rear end steel wires on the reel 11 are steadily pushed off the reel 11 and dropped onto the trunk 12 to complete the unloading, avoiding the phenomenon of wire clamping and wire breakage of the steel wire 14, ensuring that the steel wire 14 moves smoothly from the reel 11 to the trunk 12 and then falls onto the flower fence, thereby improving production efficiency.
