Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable forming technologies such as continuous extrusion, in particular to a wire pay-off rack and a continuous extrusion machine assembly. Background Art

[0002] During the process of continuously extruding wire and cable, due to factors such as the irregular bundling of the aluminum rod wire reels themselves, the loose arrangement of the aluminum rods, and the relatively large diameter of the wire reels, situations such as the aluminum rods getting tangled and knotted easily occur during the pay-off process of the aluminum rods, resulting in the aluminum rods being jammed. If not dealt with in time, it will cause the aluminum rods to break, and even damage the wire pay-off rack, resulting in losses.

[0003] Currently, in order to achieve smooth pay-off of aluminum rods, a wire arranging device is usually set on the wire pay-off rack. For example, in patents CN220723165U and CN202028634U, by setting wire arranging devices such as a wire arranging cage or a wire passing loop, although it can make the pay-off of aluminum rods smooth to a certain extent; however, it still cannot completely avoid the situation of aluminum rods getting tangled and knotted. When the aluminum rods get tangled, it is necessary to manually shake the aluminum rods to solve the knotting problem, which increases the labor intensity. Moreover, when using the method of manually shaking the aluminum rods, workers also need to pay attention to observing the pay-off situation of the wire reel, wasting manpower.

[0004] Therefore, there is an urgent need to provide a wire pay-off rack to solve the above problems existing in the prior art. Summary of the Utility Model

[0033] The purpose of the present utility model is to provide a wire pay-off rack and a continuous extrusion machine assembly, which can effectively solve the problem of aluminum rod knotting, reduce the labor intensity, and save manpower.

[0034] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Embodiment 1

[0036] As Figures 1 - 3 shown, in this embodiment, a wire pay-off rack is provided, which mainly includes:

[0037] A main frame body, on which a wire guiding wheel group is arranged for guiding the aluminum rod;

[0038] A wire arranging mechanism 2, on which a wire passing hole is arranged for the aluminum rod to pass through smoothly;

[0039] A vibration device, which is arranged on the wire arranging mechanism 2 for untying the knotted part of the aluminum rod through vibration.

[0040] In this embodiment, a wire arranging mechanism 2 is provided. The wire arranging mechanism 2 is provided with a wire passing hole through which the aluminum rod can pass smoothly; moreover, a vibration device is also arranged on the wire arranging mechanism 2, which can untie the knotted part of the aluminum rod through vibration, so as to effectively solve the problem of aluminum rod knotting and reduce the labor intensity.

[0041] In this embodiment, as Figure 1 shown, the main frame body is an inverted L-shaped bracket, which mainly includes a vertical support beam 5 and a horizontal cross beam 4. The bottom of the vertical support beam 5 is fixed to the ground through a fixed base, one end of the horizontal cross beam 4 is connected to the top of the vertical support beam 5, and the horizontal cross beam 4 is perpendicular to the vertical support beam 5.

[0042] In this embodiment, the wire guiding wheel group includes three wire guiding wheels 3. Among them, two wire guiding wheels 3 are respectively arranged above the two ends of the horizontal cross beam 4, and the other wire guiding wheel 3 is arranged at the bottom of the side of the vertical support beam 5 facing away from the horizontal cross beam 4; among them, it should be noted that the specific number and installation position of the wire guiding wheels 3 can also be adjusted according to the working needs as long as the wire requirements can be met.

[0043] In this embodiment, as Figure 2 shown, the wire management mechanism 2 mainly includes a guide frame 202 and a connecting arm 204. The guide frame 202 is connected to the vertical support beam 5 through the connecting arm 204, and a wire passing hole is provided on the guide frame 202 for the aluminum rod to pass through smoothly. Among them, the connecting arm 204 is located directly below the horizontal cross beam 4, facilitating the aluminum rod to pass through the wire passing hole on the guide frame 202 and then wind around the wire guiding wheel 3. Further, a through hole is also provided at one end of the horizontal cross beam 4 away from the vertical support beam 5, and this through hole corresponds to the wire passing hole on the guide frame 202. After the aluminum rod passes through the wire passing hole on the guide frame 202, it first passes through this through hole and then winds around the wire guiding wheel 3, further ensuring the smooth passing of the aluminum rod.

[0044] In this embodiment, the guide frame 202 is preferably a cross-shaped guide frame. Alternatively, a guide frame 202 with other structures can also be selected according to work requirements, such as a rectangular or regular polygon guide frame, etc.

[0045] In this embodiment, the vibration device is connected to one end of the guide frame 202 away from the connecting arm 204, and the guide frame 202 is connected to the connecting arm 204 through an elastic element. The setting of the elastic element can isolate vibration and prevent the vibration from being transmitted to the connecting arm 204, ensuring the stability of the connecting arm 204. Among them, the vibration device is preferably a vibration motor 201, and the elastic element is preferably a damping spring 203.

[0046] In this embodiment, a fixing plate is further provided on one side of the vertical support beam 5 close to the connecting arm 204. One end of the connecting arm 204 away from the guide frame 202 is rotatably connected to the fixing plate through a rotating shaft 205, and the connecting arm 204 can rotate up and down around the rotating shaft 205. Specifically, the fixing plate is vertically arranged on the vertical support beam 5, and the rotating shaft 205 is horizontally arranged and perpendicular to the fixing plate, so that the connecting arm 204 can rotate up and down.

[0047] In this embodiment, a counterweight 213 is further provided at the bottom of one end of the connecting arm 204 close to the guide frame 202, so that the connecting arm 204 can be inclined downward in the initial state. An upper limit member 206 and a lower limit member 210 are also provided on the fixing plate. The upper limit member 206 and the lower limit member 210 are respectively located on the upper and lower sides of the connecting arm 204, and are used to limit the downward rotation angle and upward rotation angle of the connecting arm 204. Among them, both the upper limit member 206 and the lower limit member 210 are preferably triangular limit blocks and are symmetrically arranged up and down, facilitating the rotation of the connecting arm 204.

[0048] Further, an upper proximity switch 207, a middle proximity switch 208 and a lower proximity switch 209 are also arranged on the fixed plate. The upper proximity switch 207 is arranged close to the upper limit member 206, the lower proximity switch 209 is arranged close to the lower limit member 210, and the middle proximity switch 208 is located on one side between the upper proximity switch 207 and the lower proximity switch 209. The upper proximity switch 207, the middle proximity switch 208 and the lower proximity switch 209 are all connected to the controller in signal for feeding back the position of the connecting arm 204, and the controller is also connected to the vibration device and the continuous extruder in signal for controlling the operation of the vibration device and the continuous extruder.

[0049] In the initial state, one end of the connecting arm 204 far from the guide frame 202 abuts against the upper limit member 206 and triggers the upper proximity switch 207. When the aluminum rod knots, it drives the connecting arm 204 to rotate upward and disengage from the upper proximity switch 207, and the vibration device works to transmit vibration to the aluminum rod.

[0050] When the connecting arm 204 rotates upward to trigger the middle proximity switch 208, the continuous extruder decelerates.

[0051] When one end of the connecting arm 204 far from the guide frame 202 abuts against the lower limit member 210 when the connecting arm 204 rotates upward, the lower proximity switch 209 is triggered, and the continuous extruder stops running.

[0052] In this embodiment, the controller can control the automatic operation of the vibration device to untie the knotted part of the aluminum rod, without the need for workers to always pay attention to the wire reel wire feeding situation, saving manpower.

[0053] In this embodiment, an alarm device is further included. The alarm device is connected to the controller in signal for alarming when the aluminum rod knots to remind the on-site staff. Among them, when the connecting arm 204 disengages from the upper proximity switch 207, it is judged that the aluminum rod knots, and the alarm device alarms.

[0054] In this embodiment, the alarm device is preferably a buzzer 212, and the controller is preferably a PLC controller 211. Both are mature and existing technologies in the field, and will not be elaborated in this embodiment.

[0055] As Figure 2 and Figure 3 shown, the specific working process of the wire reel in this embodiment is as follows:

[0056] When the aluminum rod is fed smoothly, the connecting arm 204 droops, and the upper proximity switch 207 detects the connecting arm 204.

[0057] When tying a knot in the aluminum rod, it will accumulate under the guide frame 202 and pull up the connecting arm 204. At this time, the upper proximity switch 207 can detect the movement of the connecting arm 204 and feedback it to the PLC controller 211. The PLC controller 211 starts the vibration motor 201 according to the pre-set program. The vibration motor 201 transmits the vibration to the aluminum rod, unties the knotted part of the aluminum rod, and starts the buzzer 212 to prompt the on-site operator.

[0058] If the vibration cannot untie the knotted part of the aluminum rod, the connecting arm 204 will continue to rotate until the middle proximity switch 208 is triggered. At this time, the PLC controller 211 will automatically control the continuous extruder to decelerate, which can increase the troubleshooting time. During this period, the vibration motor 201 remains started and the buzzer 212 continues to beep.

[0059] If the knot in the aluminum rod has not been solved, the connecting arm 204 continues to rotate until the lower proximity switch 209 is triggered. At this time, the PLC controller 211 will automatically control the continuous extruder to stop to prevent accidents. At this time, the vibration motor 201 stops and the buzzer 212 continues to beep.

[0060] In this embodiment, a continuous extruder assembly is further provided, including a continuous extruder and the wire feeding frame as described above.

[0061] In the present utility model, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
