Description

Technical Field

[0001] This invention relates to the field of packing winding technology, and more particularly to a dual-station winding device for metal packing. Background Technology

[0002] Metal packing, as an important mass transfer element in chemical towers, is typically made of thin metal sheets with dense pores and specific embossed textures to provide a large specific surface area and good gas-liquid distribution performance. During the packing production process, large-format metal packing sheets are continuously wound onto a winding sleeve to form regular rolls for easy transportation, storage, and subsequent processing.

[0003] Traditional metal filler winding operations mostly rely on manual labor or semi-automated equipment. During operation, the end of the metal filler must first be manually fixed to the winding sleeve before the equipment is started for winding. This method has significant drawbacks: 1. Due to its material properties and perforated embossed structure, metal filler has a certain degree of elasticity and rigidity. It is difficult to achieve stable and reliable initial adhesion on smooth winding sleeves (especially vertically set sleeves). Manual operation is inefficient and difficult. 2. Currently, most winding operations adopt a single-station operation mode, and the winding and loading / unloading processes cannot be carried out in parallel. After completing a roll and cutting the filler, the equipment must be stopped to unload the finished product and install a new empty sleeve. The operation is cumbersome and continuous production cannot be achieved.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention

[0005] To address the aforementioned shortcomings, the present invention aims to provide a dual-station metal filler winding device, which solves the initial winding problem of metal filler through a guiding drive mechanism, and utilizes a dual-station design and a release mechanism to automatically monitor the roll diameter, thereby achieving high-efficiency production and improving the degree of production automation and winding efficiency.

[0006] To achieve the above objectives, the present invention provides a dual-station metal filler winding device, including a base, on which two winding mechanisms, a guide drive mechanism and a cutting and conveying mechanism are provided.

When relative rotation occurs between the drive shaft and the drive shaft, the guide ring drives the ear plate to move up and down.

[0012] According to the present invention, the metal filler dual-station winding device has a double-ear protrusion on the drive shaft, a translation stop is elastically connected to the base, a fixing plate is provided on the bottom surface of the rotary arm, a driven shaft is rotatably connected to the bottom of the drive shaft, a support plate is provided on the driven shaft, the drive gear is rotatably connected to the support plate, and torsion springs are connected between the drive shaft and the rotary arm, and between the drive shaft and the driven shaft. When the torsion spring is in its natural state, the rotary arm and the support plate are on the same vertical plane.

[0013] According to the metal filler dual-station winding device of the present invention, the base is further provided with a release mechanism.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] See Figure 1 and Figure 2This invention provides a dual-station metal filler winding device, including a base 1, winding mechanisms 2, release mechanisms 3, guide rail mechanisms 4, guide drive mechanisms 5, and cutting and conveying mechanisms 6. Two winding mechanisms 2 are arranged on the top surface of the base 1. The winding mechanisms 2 are used to position the winding sleeve 7 and drive the winding sleeve 7 to rotate, thereby achieving the winding of the metal filler. Two release mechanisms 3 are symmetrically arranged at each winding station on the base 1. The release mechanisms 3 are used to measure the thickness of the metal filler wound on the winding sleeve 7. When the thickness of the metal filler wound on the winding sleeve 7 reaches a preset value, the winding mechanisms 2 are driven to stop rotating the winding sleeve 7. A guide drive mechanism 5 is arranged at the center of the top surface of the base 1. The two winding mechanisms 2 and the two release mechanisms 3 are located on both sides of the guide drive mechanism 5. During the switching between the two stations, the guide drive mechanism 5 guides and drives the end of the metal filler to contact and wrap around the new winding sleeve 7, allowing the metal filler to be smoothly wound onto the new winding sleeve 7. A cutting and conveying mechanism 6 is provided on one side of the top surface of the base 1. The cutting and conveying mechanism 6 is used to cut and convey the metal filler, and convey the end of the metal filler to the winding sleeve 7.

[0020] See Figures 1-3 The two winding mechanisms 2 each include a sliding seat 21 and a turntable 211. The top surface of the base 1 is horizontally slidably connected to two sliding seats 21. The base 1 is provided with a relief groove 11 corresponding to the sliding seat 21. The center of each sliding seat 21 is rotatably connected to a turntable 211. The turntable 211 is used to support the winding sleeve 7. The center of the turntable 211 is provided with a hole in the vertical direction. When winding, the position of the winding sleeve 7 corresponds to the position of the hole. A central shaft 22 is provided at the turntable 211. The central shaft 22 is coaxial with the hole. Multiple abutment plates 23 are evenly arranged around the top outer side of the central shaft 22. A telescopic main connector 28 is fixedly connected between the abutment plates 23 and the central shaft 22. Abutment sliders 231 are slidably connected to the abutment plates 23 in the vertical direction. A centering connecting rod 232 is provided between the abutment sliders 231 and the central shaft 22. That is, one end of the centering connecting rod 232 is hinged to the abutment slider 231, and the other end of the centering connecting rod 232 is hinged to the central shaft 22. A driven plate 24 is slidably sleeved on the central shaft 22 below the abutment plate 23. A top shaft sleeve 241 is fixedly connected to the top surface of the driven plate 24. The top shaft sleeve 241 is sleeved outside the central shaft 22. A driving link 242 is provided between the top shaft sleeve 241 and the centering link 232. That is, one end of the driving link 242 is hinged to the top shaft sleeve 241, and the other end of the driving link 242 is hinged to the centering link 232.

[0021] When the driven plate 24 moves upward relative to the central shaft 22, the top shaft sleeve 241 rises synchronously with the driven plate 24. Under the action of the driving connecting rod 242, the centering connecting rod 232 rotates with its hinge point with the central shaft 22 as the center, driving the abutting slider 231 to slide on the abutting plate 23. At the same time, it drives the abutting plate 23 to move away from the central shaft 22, so that the abutting plate 23 tightly abuts against the inner wall of the take-up sleeve 7, realizing the centering positioning of the take-up sleeve 7. After positioning, the take-up sleeve 7 is coaxial with the central shaft 22.

[0022] See Figure 2 and Figure 3 Multiple spring seats are fixedly connected to the central shaft 22 above the top shaft sleeve 241, and each spring seat is fixedly connected to the top shaft sleeve 241 with a support spring. An active plate 25 is slidably sleeved on the central shaft 22 below the driven plate 24. A buffer spring is fixedly connected between the active plate 25 and the driven plate 24. The elastic coefficient of the buffer spring is much greater than that of the support spring. The bottom of the central shaft 22 is sleeved inside the positioning shaft sleeve 221. The central shaft 22 can reciprocate and move up and down relative to the positioning shaft sleeve 221. When winding the metal filler, the abutment plate 23 is above the turntable 211 to position and support the winding sleeve 7. After winding is completed, the abutment plate 23 and the central shaft 22 can retract into the base 1, making it easy for the user to remove the winding sleeve 7. A locking edge is fixedly connected to the top of the positioning shaft sleeve 221 to limit the maximum rising height of the central shaft 22.

[0023] See Figure 2 and Figure 3 The bottom ends of the positioning bushings 221 are fixedly connected to the base 222. The base 222 is connected to the output shaft of the switching drive (not shown in the figure). The switching drive is used to drive the base 222 to move horizontally along the length of the base 1, thereby realizing the switching between two workstations. The top surface of the active plate 25 is fixedly connected to a telescopic rod 251 that passes through the driven plate 24. The telescopic rod 251 can extend and retract. The top end of the telescopic rod 251 is fixedly connected to the bottom surface of the turntable 211, so that the active plate 25 can drive the driven plate 24 and the turntable 211 to rotate synchronously. The bottom surface of the active plate 25 is fixedly connected to a fixed bushing 252. The bottom end of the fixed bushing 252 is fixedly connected to a driven gear 26. A rotating bushing 27 is rotatably sleeved on the fixed bushing 252. Guide rods 271 are symmetrically fixedly connected to the rotating bushing 27. The guide rods 271 cooperate with the guide rail mechanism 4 to realize the automatic lifting and lowering of the active plate 25 during the horizontal movement of the base 222.

[0024] See Figure 2 , Figure 3 and Figure 5The guide rail mechanism 4 includes a translation rail 41 and a rising rail 42. The end of the translation rail 41 near the center of the base 1 is fixedly connected to the rising rail 42 with its end inclined upward. The top of the end of the rising rail 42 away from the translation rail 41 is fixedly connected to a C-shaped rail 43. The translation rail 41, the rising rail 42 and the C-shaped rail 43 are all fixedly connected to the base 1. The C-shaped rail 43 is a closed loop rail. The entrance end of the C-shaped rail 43 is connected to the top of the rising rail 42, and the exit end of the C-shaped rail 43 is connected to the upper part of the rising rail 42. A one-way limiting plate 44 is hinged at the connection between the exit end of the C-shaped rail 43 and the rising rail 42.

[0025] When the base 222 drives the central shaft 22 to move closer to the center of the base 1, the guide rod 271 enters the rising track 42 from the translation track 41. The active plate 25 drives the central shaft 22 to rise. When the guide rod 271 passes the one-way limiting plate 44, the one-way limiting plate 44 cannot rotate, so that the guide rod 271 enters from the entrance end of the C-shaped track 43. At this time, the abutment plate 23 cooperates with the winding sleeve 7 to support the winding sleeve 7.

[0026] See Figures 2-4 The disengagement mechanism 3 includes an end plate 31 and an extension plate 311. The end plate 31 is fixedly connected to the top surface of the base 1. The extension plate 311 is fixedly connected to the side wall of the end plate 31 near the center of the base 1. A translation seat 32 is slidably connected to the extension plate 311. A return spring is fixedly connected between the translation seat 32 and the end plate 31. A contact roller 321 is rotatably connected to the end of the translation seat 32 away from the end plate 31. When the winding sleeve 7 is winding, the contact roller 321 abuts against the surface of the metal filler wound on the winding sleeve 7. As the thickness of the metal filler wound on the winding sleeve 7 increases, the contact roller 321 is forced to move towards the end plate 31. A release seat 33 is horizontally slidably connected to the extension plate 311. An inclined frame 34 is provided below the end plate 31. The inclined frame 34 is fixedly connected to the base 1. A transmission rod 35 is slidably connected to the inclined frame 34. A release connecting rod 351 is provided between the transmission rod 35 and the release seat 33. That is, one end of the release connecting rod 351 is hinged to the release seat 33, and the other end of the release connecting rod 351 is hinged to the transmission rod 35. An adjustment seat 322 is detachably connected to the top surface of the translation seat 32 on the side of the release seat 33 away from the end plate 31 by fixing bolts.

[0027] When the contact roller 321 drives the translation seat 32 to move closer to the end plate 31, until the adjusting seat 322 abuts against and pushes the disengagement seat 33 to move synchronously, the disengagement linkage 351 drives the transmission rod 35 to slide downward along the inclined frame 34. By adjusting the position of the adjusting seat 322, the preset thickness of the metal filler wound on the winding sleeve 7 when the transmission rod 35 moves can be changed.

[0028] See Figures 2-4A support member 36 is provided on the bottom end of the tilting frame 34 near the center of the base 1. The support member 36 can cooperate with the active plate 25 to support the active plate 25. When the guide rod 271 moves along the horizontal area at the top of the C-shaped track 43 to the end away from the rising track 42, the active plate 25 cooperates with the support member 36. At this time, the height of the active plate 25 is locked, and the guide rod 271 cannot move downward. A tail plate 361 passing through the tilting frame 34 is fixedly connected to the side wall of the support member 36. A connecting buckle 362 is fixedly connected to the tail plate 361. A horizontal connecting shaft is fixedly connected to the connecting buckle 362. A lever 37 is hinged to the tilting frame 34 above the tail plate 361. A torsion spring is fixedly connected to the hinge point between the lever 37 and the tilting frame 34. A waist-shaped groove is provided at the bottom end of the lever 37, and the connecting shaft is located in the waist-shaped groove.

[0029] When the transmission rod 35 slides down along the inclined frame 34, its bottom end abuts against and pushes the lever 37 to rotate. When the lever 37 rotates, under the cooperation of the connecting shaft and the waist-shaped groove, it drives the support 36 to move closer to the inclined frame 34 until the support 36 disengages from the active plate 25. At this time, the guide rod 271 descends from the top to the bottom of the C-shaped track 43. If the base 222 drives the central shaft 22 to move away from the center of the base 1, the guide rod 271 enters the rising track 42 at the exit end of the C-shaped track 43. During this process, the one-way limiting plate 44 rotates and automatically resets under the action of gravity, and will not block the guide rod 271.

[0030] See Figure 1 , Figure 2 and Figure 6 The guide drive mechanism 5 includes a drive shaft 51 and a rotary arm 52. The drive shaft 51 is rotatably connected to the center of the top surface of the base 1. The top end of the drive shaft 51 is rotatably connected to a fixed frame 12, which is fixedly connected to the top surface of the base 1. A shifting drive component 511 is fixedly mounted on the fixed frame 12. The output shaft of the shifting drive component 511 is connected to the drive shaft 51 via a coupling. The shifting drive component 511 can drive the drive shaft 51 to rotate. A rotary arm 52 is rotatably sleeved on the drive shaft 51 located above the base 1. A torsion spring is fixedly connected at the connection between the rotary arm 52 and the drive shaft 51. A primary winding seat 521 is horizontally slidably connected to the rotary arm 52. A primary winding roller 53 is rotatably connected to the end of the primary winding seat 521 away from the drive shaft 51.

[0031] After replacing the take-up sleeve 7, the initial winding roller 53 needs to press the metal filler against the surface of the take-up sleeve 7. The static friction generated between the metal filler and the take-up sleeve 7 is used to overcome the tension of the metal filler itself, thereby gripping and starting the winding. After the take-up sleeve 7 rotates a certain number of times (usually 3 to 5 times), the metal filler wound on the take-up sleeve 7 can achieve self-locking. At this time, the initial winding roller 53 and the metal filler are no longer in contact.

[0032] See Figure 1 , Figure 2 and Figure 6 A vertical frame 522 is fixedly connected to one end of the initial winding base 521 near the drive shaft 51. A lifting slider 523 is slidably connected to the vertical frame 522. An initial winding connecting rod 524 is provided between the lifting slider 523 and the top surface of the rotary arm 52. One end of the initial winding connecting rod 524 is hinged to the lifting slider 523, and the other end is hinged to the rotary arm 52. A limiting bushing 543 is rotatably sleeved on the drive shaft 51 at the rotary arm 52. The limiting bushing 543 is fixedly connected to the rotary arm 52. A guide shaft 54 ​​is slidably passed through the limiting bushing 543. Ear plates 541 are fixedly connected to the top and bottom ends of the guide shaft 54. An active connecting rod 542 is provided between the ear plate 541 at the top of the guide shaft 54 ​​and the initial winding connecting rod 524. That is, one end of the active connecting rod 542 is hinged to the ear plate 541, and the other end of the active connecting rod 542 is hinged to the initial winding connecting rod 524. A protruding post is fixedly connected to the bottom surface of the lower ear plate 541. A guide ring 512 is fixedly connected to the drive shaft 51 below the protruding post. The guide ring 512 is a semi-circular structure that gradually rises from the middle to both ends. When the torsion spring between the rotary arm 52 and the drive shaft 51 is in its natural state, the protruding post is located in the middle of the guide ring 512. At this time, the initial winding roller 53 does not cooperate with the winding sleeve 7.

[0033] See Figure 1 , Figure 2 and Figure 6The bottom end of the drive shaft 51 extends into the base 1 and is rotatably connected to the driven shaft 56. The bottom end of the driven shaft 56 is fixedly connected to a horizontal support plate 561. A torsion spring is fixedly connected at the connection between the drive shaft 51 and the driven shaft 56. When the torsion spring is in its natural state, the support plate 561 and the rotary arm 52 are on the same vertical plane. The end of the support plate 561 away from the driven shaft 56 is rotatably connected to the drive gear 562. When the drive plate 25 is engaged with the support member 36 and the support plate 561 is facing the drive plate 25, the drive gear 562 meshes with the driven gear 26 on the drive plate 25. A winding drive member 563 is fixedly installed on the support plate 561. The output shaft of the winding drive member 563 is connected to the drive gear 562, and the winding drive member 563 is used to drive the drive gear 562 to rotate. A reinforcing rib 57 is fixedly connected between the support plate 561 and the driven shaft 56 to prevent the end of the support plate 561 from tilting under the gravity of the drive gear 562 and the winding drive 563, thus achieving precise meshing between the drive gear 562 and the driven gear 26. An insert plate 571 extending away from the driven shaft 56 is fixedly connected to the top of the reinforcing rib 57. A locking piece 212 for limiting the insertion plate 571 is fixedly connected to the sliding seat 21. When the driven gear 26 meshes with the drive gear 562, the sliding seat 21 corresponding to the driven gear 26 is located at the end of the clearance groove 11 near the center of the base 1. The locking piece 212 corresponds to the insert plate 571. At this time, the drive shaft 51 cannot drive the driven shaft 56 to rotate, allowing the drive shaft 51 to reset independently after the winding sleeve 7 and the metal filler complete the initial winding, preventing the initial winding roller 53 from obstructing normal winding operations. The drive gear 562 and the driven gear 26 remain in mesh for continuous winding.

[0034] See Figure 1 , Figure 2 and Figure 6 A stop block is fixedly connected to the top surface of the base 1. The stop block is located next to the drive shaft 51 and is used to limit the movement range of the rotary arm 52. When the rotary arm 52 abuts against the stop block, the initial winding roller 53 is directly opposite the take-up sleeve 7. At this time, the axis of the drive shaft 51, the axis of the initial winding roller 53, and the axis of the take-up sleeve 7 are on the same vertical plane. A fixing plate 525 is fixedly connected to one end of the bottom surface of the rotary arm 52 near the drive shaft 51. A translation stop 551 is provided on both sides of the drive shaft 51 near the take-up sleeve 7. The translation stop 551 is horizontally slidably connected to the top surface of the base 1. A guide groove corresponding to the translation stop 551 is opened on the top surface of the base 1. A compression spring is provided in the guide groove. The two ends of the compression spring are fixedly connected to the side wall of the guide groove and the side wall of the translation stop 551, respectively. When the compression spring is in its natural state, the translation stop 551 does not contact the fixing plate 525. A double-eared protrusion 55 is fixedly connected to the drive shaft 51. When the drive shaft 51 rotates relative to the rotary arm 52, the double-eared protrusion 55 can push the translation stop 551 to move.

[0035] See Figure 1 , Figure 2 and Figure 6 When winding is required, the shift drive 511 is activated, causing the drive shaft 51 to drive the driven shaft 56 to rotate synchronously toward the winding sleeve 7. At this time, the sliding seat 21 carrying the winding sleeve 7 moves toward the center of the base 1. The locking piece 212 on the sliding seat 21 cooperates with the insert plate 571 on the reinforcing rib 57 to lock the angle of the driven shaft 56. At this time, the rotary arm 52 abuts against the stop block, the initial winding roller 53 is facing the winding sleeve 7, the drive shaft 51 continues to rotate in the original direction, and the rotary arm 52 cannot rotate synchronously with the drive shaft 51. The torsion spring between the drive shaft 51 and the rotary arm 52 deforms. The drive shaft 51 drives the guide ring 512 and the double-eared protrusion 55 to rotate synchronously. Since the guide ring 512 is shaped with a low center and high sides, the rotation of the guide ring 512 forces the guide shaft 54 ​​to rise, thereby driving the initial winding roller 53 to press the metal filler onto the take-up sleeve 7. When the double-eared protrusion 55 rotates, it can push the translation stop 551 to cooperate with the fixed plate 525 to lock the rotary arm 52, preventing it from shaking when assisting in the initial winding and ensuring the smooth progress of the initial winding operation. It should be noted that the cooperation between the translation stop 551 and the double-eared protrusion 55 is earlier than the contact between the initial winding roller 53 and the metal filler, to prevent the rotary arm 52 from malfunctioning when the initial winding roller 53 squeezes the metal filler onto the take-up sleeve 7.

[0036] See Figure 1 and Figure 7 The cutting and conveying mechanism 6 includes a sliding bracket 61 and a guide wheel 611. The sliding bracket 61 is horizontally slidably connected to the top surface of the base 1. A transfer drive 69 is fixedly installed on the top surface of the base 1 on one side of the sliding bracket 61. The output shaft of the transfer drive 69 is fixedly connected to the sliding bracket 61, and the transfer drive 69 can drive the sliding bracket 61 to slide between two winding stations. A drive roller 62 is rotatably connected to the sliding bracket 61, and a conveying drive 621 is fixedly installed on the sliding bracket 61. The output shaft of the conveying drive 621 is connected to the drive roller 62 through a coupling. An auxiliary frame 63 is horizontally slidably connected to the sliding bracket 61 on one side of the drive roller 62, and a driven roller 631 is rotatably connected to the auxiliary frame 63. When the drive roller 62 and the driven roller 631 abut and squeeze the metal filler, the rotation of the drive roller 62 can convey the metal filler.

[0037] See Figure 1 and Figure 7A fixed clamp 65 is fixedly connected to a sliding bracket 61 on the side of the active roller 62 near the center of the base 1. A sliding clamp 651 is slidably connected to the side of the fixed clamp 65 near the driven roller 631. The sliding clamp 651 and the auxiliary frame 63 are both fixedly connected to the frame plate 66. A mounting frame 67 is fixedly connected to the side wall of the sliding bracket 61 near the frame plate 66. A clamping drive 671 is fixedly installed on the mounting frame 67. The output shaft of the clamping drive 671 is connected to the frame plate 66. By setting the frame plate 66 and the clamping drive 671, the positions of the driven roller 631 and the sliding clamp 651 can be adjusted. A blade holder 64 is vertically slidably connected to a sliding bracket 61 between the drive roller 62 and the fixed clamp 65. A blade 641 for cutting metal filler is fixedly connected to the blade holder 64. The blade holder 64 is located at both ends of the blade 641. When the blade 641 cuts the metal filler, the blade holder 64 does not contact the metal filler. A cutting edge strip 68 corresponding to the blade 641 is fixedly installed on the sliding bracket 61 below the blade 641 to assist in completing the cutting operation.

[0038] When the thickness of the metal filler on the winding sleeve 7 reaches the preset value, the conveying drive 621 stops running, the drive roller 62 stops rotating, and the conveying of the metal filler stops. Then the clamping drive 671 starts, pushing the auxiliary frame 63 and the sliding clamp 651 to move. The drive roller 62 and the driven roller 631 cooperate, and the fixed clamp 65 and the sliding clamp 651 cooperate to clamp the metal filler. Then the cutting drive 642 starts, causing the knife holder 64 to drive the blade 641 to descend and cut the metal filler. Then the transfer drive 69 starts, driving the sliding bracket 61 to move to another station to continue the winding operation.

[0039] See Figure 1 and Figure 7 Preferably, the surfaces of both the drive roller 62 and the driven roller 631 are made of materials with high friction coefficient and certain elasticity, such as polyurethane and rubber. When the driven roller 631 and the drive roller 62 abut against the metal filler and undergo slight deformation to achieve conveying, there is a small gap between the sliding clamp 651 and the fixed clamp 65 for the metal filler to pass through. When the sliding clamp 651 and the fixed clamp 65 squeeze the metal filler to fix it, the driven roller 631 and the drive roller 62 undergo large deformation to ensure good clamping effect.

[0040] See Figure 1 and Figure 7 Preferably, two sets of fixed clamps 65 and sliding clamps 651 can be provided, and the knife holder 64 is installed between the two fixed clamps 65. Through the cooperation of the two sets of fixed clamps 65 and sliding clamps 651, the metal filler can be rigidly fixed, thereby further improving the cutting effect.

[0041] See Figure 4Preferably, a fixing kit 341 is fixedly connected to the tilting frame 34, and the transmission rod 35 passes through the fixing kit 341. The fixing kit 341 can provide a guiding function for the transmission rod 35.

[0042] See Figure 6 Preferably, a support 581 is fixedly installed on the side wall of the vertical frame 522 away from the drive shaft 51. A guide drive 582 is fixedly installed on the support 581. The output shaft of the guide drive 582 is connected to the arc plate 58. Multiple horizontal guide shafts are fixedly connected to the support 581. The guide shafts all pass through the arc plate 58 and are used to guide the arc plate 58. The open end of the arc plate 58 is away from the drive shaft 51. A clearance space corresponding to the initial winding roller 53 is provided in the middle of the arc plate 58. The curvature of the inner wall of the arc plate 58 is adapted to the outer circumferential surface of the winding sleeve 7. When the two are in combination, a material guiding channel can be formed between the arc plate 58 and the winding sleeve 7 (precise positioning of the arc plate 58 can be achieved by setting a positioning component on the guide shaft, which is existing technology and will not be described in detail here), improving the initial winding success rate.

[0043] See Figure 3 and Figure 6 Preferably, a precision guide rail (e.g., a splined guide mechanism) corresponding to the central shaft 22 can be installed in the positioning sleeve 221 to prevent the central shaft 22 from deflecting or vibrating. A damping element is installed between the positioning sleeve 221 and the central shaft 22. The damping element can be a pneumatic damper or a hydraulic damper (dampers are mature existing technology, and their installation method and working principle are common knowledge to those skilled in the art, so they will not be described in detail). When the buffer spring and the support spring recover their deformation and push the driven gear 26 downward, the damping element buffers the release impact of the buffer spring and the support spring, allowing the driven gear 26 to descend smoothly. At the same time, in order to achieve smooth disengagement of the driven gear 26 from the driving gear 562, the meshing tooth ends of the driving gear 562 and the driven gear 26 are rounded for cost considerations. When the driven gear 26 descends, the rounded tooth ends can form a smooth curved surface contact and transition with the tooth surface of the mating gear, avoiding sharp edge scraping at the moment of disengagement, thereby reducing the impact force.

[0044] See Figure 4 Preferably, a retaining spring is fixedly connected between the support member 36 and the tilting frame 34, so that when the retaining spring is in its natural state, the support member 36 can cooperate with the active plate 25.

[0045] See Figure 7 Preferably, the sliding bracket 61 is rotatably connected to multiple sets of guide wheels 611 for guiding the metal filler so that it can accurately reach between the winding sleeve 7 and the initial winding roller 53.

[0046] See Figure 6 Preferably, vertical guide rollers can be rotatably connected at both ends of the arc plate 58. The guide rollers reduce the friction between the metal filler and the arc plate 58, and at the same time prevent the metal filler from scratching the arc plate 58, which would affect the product quality of the metal filler.

[0047] See Figures 1-7 The switching drive, transfer drive 69, clamping drive 671 and guiding drive 582 are all cylinders, the shifting drive 511, conveying drive 621 and winding drive 563 are all rotary motors, and the cutting drive 642 is a hydraulic cylinder, which can provide sufficient power.

[0048] In the implementation of this invention: First, the shifting drive 511 is started, so that the drive shaft 51 drives the driven shaft 56 to rotate synchronously. The rotary arm 52 and the support plate 561 move toward one of the clearance grooves 11 until the rotary arm 52 abuts the stop block. Then, the conveying drive 621 is started, and the drive roller 62 and the driven roller 631 abut against the metal filler. The drive roller 62 drives the metal filler to move. Under the action of multiple sets of guide rollers 611, the metal filler reaches between the initial winding roller 53 and the winding sleeve 7.

[0049] Simultaneously, the drive unit is activated, causing the base 222 to move horizontally along the length of the base 1. This moves one of the sliding seats 21 to the end of its clearance groove 11 near the center of the base 1, while the other sliding seat 21 is located at the end of its clearance groove 11 away from the center of the base 1. As the sliding seat 21 moves towards the center of the base 1, the guide rod 271 corresponding to the sliding seat 21 moves from the translation track 41 to the rising track 42 and then passes through the one-way limiting plate 44 to reach the entrance end of the C-shaped track 43. The guide rod 271 moves horizontally along the top of the C-shaped track 43 for a distance, reaching the end of the C-shaped track 43 away from the rising track 42. At this time, the active plate 25 corresponding to the guide rod 271 cooperates with the support 36 at the workstation to lock the height of the active plate 25, and the driven gear 26 on the guide rod 271 meshes with the active gear 562.

[0050] During the aforementioned movement, the active plate 25 rises relative to the base 222. Initially, neither the support spring nor the buffer spring deforms (or deforms slightly), causing the active plate 25 to drive the central shaft 22 to rise synchronously. The central shaft 22 extends out of the through hole, and the abutment plate 23 reaches above the turntable 211. The winding sleeve 7 is located outside the abutment plate 23 (the winding sleeve 7 can be transferred manually or automatically; this is existing technology and will not be described further). When the bottom end of the central shaft 22 contacts the positioning sleeve 2... When the top edge of plate 21 is locked, the central shaft 22 cannot continue to rise. Since the elastic coefficient of the buffer spring is much greater than that of the support spring, when the driving plate 25 continues to rise, the support spring is compressed first. The driven plate 24 rises relative to the central shaft 22. Under the cooperation of the centering link 232 and the drive link 242, multiple abutment plates 23 move synchronously away from the central shaft 22. The abutment plates 23 abut against and squeeze the inner wall of the winding sleeve 7. The driven plate 24 cannot continue to rise, the driving plate 25 continues to rise, and the buffer spring is compressed.

[0051] When the sliding seat 21 moves to the end of the clearance groove 11 near the center of the base 1, multiple abutment plates 23 abut against and squeeze the inner wall of the winding sleeve 7, and the driven gear 26 meshes with the driving gear 562. At this time, the metal filler is located between the winding sleeve 7 and the initial winding roller 53. Then, the shift drive 511 is activated to make the drive shaft 51 continue to rotate in the original direction. Since the rotary arm 52 abuts against the stop block at this time, and the locking piece 212 and the insert plate 571 are in a cooperating state, the drive shaft 51 cannot drive the rotary arm 52 and the driven shaft 56 to rotate. During the rotation of the drive shaft 51, the double-ear protrusion 55 pushes the translation stop 551 to cooperate with the fixing piece 525 on the bottom surface of the rotary arm 52 to lock the rotary arm 52. The drive shaft 51 drives the guide ring 512 to rotate, forcing the convex post to move upward, thereby causing the guide shaft 54 ​​and ear plate 541 to rise synchronously. Under the action of the drive connecting rod 542 and the initial winding connecting rod 524, the initial winding seat 521 moves towards the winding sleeve 7. The initial winding roller 53 applies a large extrusion force to the metal filler, generating a large static friction force between the metal filler and the winding sleeve 7 to overcome the tension of the metal filler itself, forcing the metal filler to wind onto the winding sleeve 7. The guide drive 582 is activated, and the guide drive 582 drives the arc plate 58 to cooperate with the winding sleeve 7 to form a material guiding channel, further improving the stability of the initial winding. During the process of the arc plate 58 moving to cooperate with the winding sleeve 7, it will force some of the metal filler to deform, which allows the drive roller 62 and the driven roller 631 to transport more metal filler, providing a certain length compensation for the deformation of the metal filler.

[0052] The winding drive 563 is activated, and the driving gear 562 and driven gear 26 mesh to rotate the driving plate 25. The driving plate 25 drives the turntable 211 to rotate through multiple telescopic rods 251, winding the metal filler. During this process, the conveying drive 621 can be activated for assistance. The speeds of the winding drive 563 and the conveying drive 621 need to be coordinated in advance. After the metal filler and the winding sleeve 7 have completed the initial winding (generally after the winding sleeve 7 has rotated 3 to 5 times, the metal filler can achieve self-locking), the shifting drive 511 is activated and reversed, causing the guide shaft 54 ​​and ear plate 541 to descend, the initial winding roller 53 to retract, the double ear protrusion 55 to disengage from the translation stop 551, and the translation stop 551 to disengage from the fixing plate 525. Start the guide drive 582 to reset the arc plate 58. At this time, the drive shaft 51 drives the rotary arm 52 to reset to the initial state. During this process, because the clamp 212 and the insert plate 571 are in a cooperating state, the driven shaft 56 cannot be reset, and the drive gear 562 and the driven gear 26 are always in a meshing state.

[0053] As the thickness of the metal filler wound on the winding sleeve 7 gradually increases, the contact roller 321 drives the translation seat 32 to move gradually closer to the end plate 31. During its movement, the adjusting seat 322 abuts against and pushes the disengagement seat 33 to move. Under the action of the disengagement linkage 351, the transmission rod 35 slides down along the inclined frame 34, pushing the lever 37 to rotate. When the lever 37 rotates, it drives the support 36 to move away from the active plate 25. When the preset metal filler thickness threshold is reached, the support 36 disengages from the active plate 25. Under the action of the buffer spring and the support spring, the active plate 25 descends, and the guide rod 271 moves from the top of the C-shaped track 43 to the bottom, and the turntable 211 stops rotating.

[0054] Start the clamping drive 671, which drives the driven roller 631 and the sliding clamp 651 to move. The driving roller 62, driven roller 631, fixed clamp 65 and sliding clamp 651 clamp and fix the metal packing. Start the cutting drive 642, which drives the knife holder 64 and the blade 641 to descend, and completes the cutting operation of the metal packing.

[0055] Then, the switching drive is activated, the work station is changed, and as the sliding seat 21 where the winding sleeve 7 is located moves away from the center of the base 1, the guide rod 271 corresponding to the sliding seat 21 enters the rising track 42 from the exit end of the C-shaped track 43 and returns to the translation track 41. The abutment plate 23 retracts into the base 1, facilitating the unloading of the winding sleeve 7. The above process is repeated to wind metal filler onto the winding sleeve 7 at another work station.

[0056] This invention provides a dual-station winding device for metal fillers, which has the following advantages: 1. By setting up a guiding drive mechanism, using the initial winding roller and the arc plate, the end of the metal filler can be tightly pressed onto the surface of the new winding sleeve after the station is switched, which solves the problem of easy falling off due to gravity, ensures the firmness and stability of the winding starting point, requires no manual intervention, and has a high success rate. 2. The dual-station design, combined with the cutting and conveying mechanism and switching process, allows the winding and loading / unloading processes of the two stations to be carried out alternately, achieving near-uninterrupted continuous production, reducing equipment idle waiting time and improving production efficiency. 3. The winding diameter is monitored in real time by the contact roller. When the preset thickness is reached, the winding mechanism can be stopped and disengaged from the drive. The winding diameter detection and control process is purely mechanical, with reliable response and stable structure, avoiding the misjudgment or failure that may occur in electrical sensors in complex industrial environments. 4. The winding mechanism adopts a design that is liftable and has a self-centering tensioning function. It can reliably clamp winding sleeves with different inner diameters and can retract during unloading to facilitate unloading. The guide rail mechanism and C-shaped track design, together with the one-way limit plate, realizes the automated sequence control of lifting and locking.

[0057] In summary, the beneficial effects of this invention are as follows: the initial winding problem of metal filler is solved by the guiding drive mechanism, and the roll diameter is monitored by the dual-station design and the unwinding mechanism, which achieves high-efficiency production and improves winding efficiency.
