Description

Technical Field

[0001] This utility model relates to the technical field of wire feeding equipment, and in particular to a reel-type shrink-and-feed rack. Background Technology

[0002] The Chinese utility model patent with patent number ZL202222858435.2 and patent name, entitled "A Wire Paying Rack," specifically discloses the following technical solution: A wire paying rack includes a frame and a speed control box mounted on the frame. A wire storage rack is mounted at one end of the frame. A wire paying assembly is mounted on the mounting plate of the frame. The wire paying assembly includes a reduction motor composed of a worm gear transmission assembly and a wire paying drive motor, and a wire paying drum driven by the reduction motor. The wire storage rack includes a pre-storage rack mounted on the frame via a carrier plate. A sensor is mounted near the top and bottom of the pre-storage rack. A slider is vertically slidably mounted on the pre-storage rack. A first guide wheel is rotatably mounted on the slider, and a second guide wheel is rotatably mounted on the top of the pre-storage rack. A wire shaping assembly is mounted on the top of the frame.

[0003] During the operation of the aforementioned wire feeding frame, as the wire tip is continuously fed, the wire will pull the slider upward. When the sensor located above the pre-storage frame detects the slider, the speed control box controls the wire feeding drive motor to work, driving the wire feeding drum to rotate (loosening the fixing of the wire tail end) and performing the wire feeding operation. At this time, the slider will slide downward under the action of gravity. During the downward sliding process of the slider, the wire can always be kept taut. When the sensor located below the pre-storage frame detects the slider, the speed control box controls the wire feeding drive motor to stop working. At this time, the pre-storage frame completes the wire pre-storage.

[0004] It should be noted that the aforementioned wire feeding frame still has the following defects, specifically: Defect 1: When the wire released by the wire release assembly is continuously fed forward through the wire storage rack and the wire shaping assembly, if the wire in front is suddenly tightened, the wire release drum driven by the geared motor reacts slowly and the wire will be pulled apart due to the sudden and rapid tightening. Defect 2: The wire feeding rack does not have a missing wire detection function. Utility Model Content

[0005] The purpose of this utility model is to provide a roll-type retractable cable reel to address the shortcomings of existing technologies. This roll-type retractable cable reel has a novel structural design, stable and reliable cable reeling, and can realize a missing cable sensing function.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0007] A reel-type shrink-out wire feeding rack includes a frame, on which a wire feeding assembly, a first wire storage rack, and a straightener are arranged sequentially along the wire feeding direction. The wire feeding assembly includes a geared motor mounted on the frame, and a wire feeding drum is mounted on the power output shaft of the geared motor. The frame is also equipped with a second wire storage rack and a wire feeding wheel assembly. The wire fed by the straightener passes through the wire feeding wheel assembly and the second wire storage rack in sequence. The wire feed wheel assembly includes a wire feed wheel drive motor that is fastened to the frame, a left wire feed wheel and a right wire feed wheel that are rotatably mounted on the frame via a rotating shaft, and the power output shaft of the wire feed wheel drive motor is connected to one of the rotating shafts via a coupling; The rack is equipped with a missing wire sensing component on the wire conveying path.

[0008] The missing wire sensing component includes a wire-passing block installed on the frame. The wire-passing block has a wire-passing hole for the wire to pass through, and a notch communicating with the wire-passing hole. A movable swing arm is pivotally connected to the notch via a pivot, and a missing wire sensor is installed on the wire-passing block corresponding to the movable swing arm. When a wire passes through the wire-passing hole of the wire-passing block, the free end of the movable swing arm rests on the wire and is far away from the wire-missing sensor. When no wire passes through the through hole of the wire guide block, the free end of the movable swing arm swings downward and triggers the missing wire sensor.

[0009] The left-side rotating shaft fastening sleeve is equipped with a left-side gear, and the right-side rotating shaft fastening sleeve is equipped with a right-side gear, with the left-side gear meshing with the right-side gear.

[0010] The wire feeding wheel assembly also includes a wire block that is fastened to the frame, and the wire block has a wire hole that aligns with the gap between the left wire feeding wheel and the right wire feeding wheel.

[0011] The wire feeding drum includes a wire feeding shaft connected to the power output shaft of the geared motor and arranged horizontally. The wire feeding shaft is fastened with a fixed limiting plate, and the fixed limiting plate is radially slidably equipped with a number of guide posts surrounding the periphery of the wire feeding shaft. A movable limiting plate is fitted on the side of the wire feeding shaft away from the geared motor. The movable limiting plate has elongated holes that pass through the axial direction and extend radially, respectively, corresponding to the guide post. An adjusting handle for adjusting the axial position of the movable limiting plate is screwed onto the end of the wire feeding shaft. A fixed limiting plate has an indexing plate rotatably mounted on its surface near the geared motor. The indexing plate has an adjustment groove with an arc-shaped bend for each guide post. The end of each guide post near the fixed limiting plate is embedded into the corresponding adjustment groove. The fixed limiting plate is equipped with a locking device for the indexing plate. When the locking device is in the locked state, the indexing plate is locked and fixed to the fixed limiting plate by the locking device.

[0012] Compared with the prior art, the present invention has the following beneficial effects, specifically: 1. When the wire in front is suddenly and rapidly tightened, this utility model can quickly start the wire feeding wheel assembly to achieve rapid wire feeding, so as to avoid the wire in front being over-tightened and broken; after the wire feeding wheel assembly is activated, the reduction motor of the wire feeding assembly is activated, so that the entire wire feeding frame has a double wire buffer protection function and can react quickly when the wire in front is tightened; compared with the prior art, the reel-type shrink wire feeding frame of this utility model has better stability and reliability; 2. When the wire in the wire reel is depleted, this utility model can sense the depletion of wire through a wire shortage sensing component to achieve wire shortage detection; 3.

Detailed Implementation

[0021] The present invention will now be described in conjunction with specific embodiments.

[0022] Example 1, as Figure 1 and Figure 2 As shown, a reel-type shrink-out wire feeding rack includes a frame 1. The frame 1 is equipped with a wire feeding assembly 2, a first wire storage rack 31, and a straightener 4 arranged sequentially along the wire feeding direction. The wire feeding assembly 2 includes a geared motor 21 installed on the frame 1. The power output shaft of the geared motor 21 is equipped with a wire feeding drum 22.

[0023] Among them, such as Figure 1 and Figure 2 As shown, the frame 1 is also equipped with a second wire storage rack 32 and a wire feeding wheel assembly 5. The wire fed by the straightener 4 passes through the wire feeding wheel assembly 5 and the second wire storage rack 32 in sequence.

[0024] It should be explained that the first wire storage rack 31 and the second wire storage rack 32 in this embodiment are wire storage rack structures with sensor structures, and their structural forms can be the same as those in the prior art. As the first wire storage rack 31 and the second wire storage rack 32 in this embodiment have been disclosed in the prior art, they will not be described in detail here.

[0025] Furthermore, such as Figures 1 to 4 As shown, the wire feeding wheel assembly 5 includes a wire feeding wheel drive motor 51 that is fastened to the frame 1, a left wire feeding wheel 52 and a right wire feeding wheel 53 that are rotatably mounted on the frame 1 via a rotating shaft (not shown in the figure), and the power output shaft of the wire feeding wheel drive motor 51 is connected to one of the rotating shafts via a coupling 54.

[0026] Furthermore, the rack 1 is equipped with a missing wire sensing component 6 on the wire conveying path.

[0027] It should be noted that the frame 1 of this embodiment is equipped with an electrical control box (not shown in the figure), and the geared motor 21, the wire feeding wheel drive motor 51 and the wire shortage sensing component 6 are electrically connected to the electrical control box respectively; during operation, the electrical control box controls the geared motor 21 and the wire feeding wheel drive motor 51 to operate respectively.

[0028] In the operation of the reel-type retractable wire feeding frame in this embodiment, the wound wire is placed on the wire feeding drum 22. The wire fed from the wire feeding drum 22 passes sequentially through the first wire storage frame 31, the straightener 4, the wire feeding wheel assembly 5, and the second wire storage frame 32. The wire is fed forward under the pulling action of the external equipment. When the external equipment pulls the wire forward, the sensor of the second wire storage frame 32 receives a signal and feeds the signal back to the electrical control box. The electrical control box controls the wire feeding wheel drive motor 51 to start, thereby causing the left wire feeding wheel 52 and the right wire feeding wheel 53 to rotate and achieve rapid wire feeding. When the sensor of the first wire storage frame 31 receives a signal, the electrical control box controls the reduction motor 21 to start and cause the wire feeding drum 22 to rotate, thereby releasing the wire.

[0029] It should be emphasized that when the front wire is suddenly and rapidly tightened, this embodiment can quickly start and achieve rapid wire feeding through the wire feeding wheel assembly 5 to avoid the front wire being over-tightened and broken; after the wire feeding wheel assembly 5 is activated, the reduction motor 21 of the wire feeding assembly 2 is activated, so that the entire wire feeding frame has a double wire buffer protection function and can react quickly when the front wire is tightened; compared with the prior art, the reel-type shrink wire feeding frame of this embodiment has better stability and reliability.

[0030] It should be further emphasized that when the wire in the wire reel 22 is exhausted, this embodiment can sense the exhaustion of wire through the wire shortage sensing component 6, and the wire shortage sensing component 6 can feed back the wire shortage signal to the electrical control box to realize wire shortage sensing.

[0031] In summary, through the above structural design, the roll-type retractable wire feeding rack of this embodiment has the advantages of novel structural design, stable and reliable wire feeding, and can realize the missing wire sensing function. Example 2, as Figure 3 As shown, the difference between this embodiment 2 and embodiment 1 is that the missing wire sensing component 6 includes a wire threading block 61 installed on the frame 1. The wire threading block 61 has a wire threading through hole 611 for the wire to pass through. The wire threading block 61 has a notch 612 communicating with the wire threading through hole 611. A movable swing arm 63 is pivotally connected to the notch 612 via a pivot 62. A missing wire sensor 64 is installed on the wire threading block 61 corresponding to the movable swing arm 63.

[0032] In this embodiment, the missing wire sensor 64 is electrically connected to the electrical control box; the missing wire sensor 64 can be a slot-type photoelectric sensor, and the movable swing arm 63 in this embodiment is equivalent to a sensing sheet structure that cooperates with the slot-type photoelectric sensor.

[0033] It should be noted that when a wire passes through the wire-passing hole 611 of the wire-passing block 61, the free end of the movable swing arm 63 rests on the wire and is far away from the wire-missing sensor 64; when no wire passes through the wire-passing hole 611 of the wire-passing block 61, the free end of the movable swing arm 63 swings downward and triggers the wire-missing sensor 64.

[0034] When all the wire in the wire feeding drum 22 has been fed out, no wire will pass through the wire feeding hole 611 of the wire feeding block 61. At this time, the movable swing arm 63 triggers the wire shortage sensor 64, which feeds back the signal to the electrical control box. The electrical control box can control the pneumatic operation of the corresponding alarm indicator to realize the wire shortage alarm. Example 3, as Figure 3 and Figure 4 As shown, the difference between this embodiment three and embodiment one is that: the left rotating shaft fastening sleeve is equipped with a left gear 55, and the right rotating shaft fastening sleeve is equipped with a right gear 56, and the left gear 55 and the right gear 56 mesh with each other.

[0035] By meshing the left gear 55 with the right gear 56, this embodiment 3 can ensure that the left wire feeding wheel 52 and the right wire feeding line rotate synchronously in opposite directions, so as to ensure the stability of the wire feeding action of the left wire feeding wheel 52 and the right wire feeding wheel 53. Example 4, as Figure 3 and Figure 4 As shown, the difference between this embodiment four and embodiment one is that the wire feeding wheel assembly 5 also includes a wire block 57 that is fastened to the frame 1. The wire block 57 has a wire hole 571 that aligns the gap between the left wire feeding wheel and the right wire feeding wheel 53.

[0036] By guiding the wire through the wire hole 571 of the guide block, this embodiment four can effectively ensure that the wire passes between the left wire feeding wheel 52 and the right wire feeding wheel 53, thereby ensuring the stability and reliability of the wire feeding action of the wire feeding wheel assembly 5. Example 5, as Figure 5 and Figure 6 As shown, the difference between this embodiment 5 and embodiment 1 is that: the wire feeding drum 22 includes a wire feeding shaft 221 connected to the power output shaft of the reduction motor 21 and arranged horizontally. The wire feeding shaft 221 is fastened with a fixed limiting plate 222. The fixed limiting plate 222 is radially slidably equipped with a number of guide posts 223 surrounding the periphery of the wire feeding shaft 221.

[0037] Among them, the wire feeding shaft 221 is fitted with a movable limiting plate 224 on the side away from the geared motor 21. The movable limiting plate 224 is provided with elongated holes 2241 that pass through the axial direction and extend radially respectively, corresponding to the guide post 223. The end of the wire feeding shaft 221 is screwed with an adjusting handle 225 for adjusting the axial position of the movable limiting plate 224.

[0038] Additionally, a dividing plate 226 is rotatably mounted on the surface of the fixed limiting plate 222 near the reduction motor 21. The dividing plate 226 has an arc-shaped adjustment groove 2261 corresponding to each guide post 223. The end of each guide post 223 near the fixed limiting plate 222 is embedded into the corresponding adjustment groove 2261. A locking device 227 is installed on the fixed limiting plate 222 corresponding to the dividing plate 226. When the locking device 227 is in the locked state, the dividing plate 226 is locked and fixed to the fixed limiting plate 222 by the locking device 227.

[0039] When loading the wire onto the wire feeding spool 22 in this embodiment five, first unscrew the adjusting handle 225 from the wire feeding shaft 221 and remove the movable limiting plate 224 from the wire feeding shaft 221. Then, insert the entire roll of wire into the guide fixing post. Next, adjust the locking device 227 to the loose state and rotate the operating indexing plate 226 so that the adjusting groove 2261 of the indexing plate 226 drives each guide post 223 to move synchronously along the radial direction of the fixed limiting plate 222 to adjust its position. This allows the guide posts 223 to tension the entire roll of wire. Finally, adjust the locking device 227 to the locked state and fix each guide post 223 in the required position. Then, put on the movable limiting plate 224 and tighten the adjusting handle 225 so that the fixed limiting plate 222 and the movable limiting plate 224 cooperate to limit the entire roll of wire.

[0040] It should be emphasized that in this fifth embodiment, the positions of all guide columns 223 can be adjusted synchronously by the indexing plate 226, so that the pay-off drum 22 of this fifth embodiment is suitable for material lines of different diameters and has strong adaptability.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
