Description

Technical Field

[0001] The present invention relates to the technical field of shaft parts production, and in particular to a fully automatic packaging device for shaft parts. Background Art

[0002] In the field of mechanical processing and parts manufacturing, shaft parts are widely used in a variety of industrial scenarios, including aerospace, automotive manufacturing, and precision instruments, due to their core functions such as transmitting torque and supporting mechanical structures. However, after machining, shaft parts need to be wrapped and wrapped to prevent damage, contamination, and rust during transportation and storage.

[0003] Existing patent publication number CN118953834A discloses a fully automatic collection and packaging device for shaft parts, which relates to the field of shaft parts production. The device comprises a conveyor belt, rotating rollers are provided at both ends of the conveyor belt, support plates are provided on both sides of the conveyor belt, the two ends of the rotating rollers are rotatably connected to the corresponding support plates, a collecting mechanism is provided at one end of the conveyor belt, and a limiting mechanism is provided on the collecting mechanism. When the driving motor is started, the rotating rollers move with the conveyor belt, and the shafts in the collecting mechanism are arranged on the conveyor belt in sequence under the cooperation of the conveyor belt and the collecting mechanism. At the same time, the collecting mechanism drives the limiting mechanism, which limits the shafts that are about to move onto the conveyor belt. The shafts on the conveyor belt are then removed by the operator at the other end of the conveyor belt for packaging and boxing, thereby allowing the shafts to move in order, facilitating the operator's subsequent sorting and boxing, and reducing the possibility of the shafts shifting when they are moving.

[0004] It can be seen that for small-diameter shafts, the packaging operation can be completed through simple adjustments, and the packaging efficiency and tightness can basically meet the requirements; but when faced with large-diameter shafts, traditional packaging cannot meet the packaging requirements. On the one hand, the large shaft itself is heavy and has a high moment of inertia, making it difficult to operate and control the shaft manually, which often leads to problems such as wrinkles, overlaps or local loosening of the stretch film, which not only affects the appearance of the packaging, but also reduces the protection effect of the shaft due to the uneven protective layer. On the other hand, manual operation of large shafts is prone to accidents and is not suitable for packaging large shafts.

[0005] In order to solve the above problems, this application proposes a fully automatic packaging device for shaft parts. Summary of the Invention

DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0023] like Figure 1 - Figure 10 As shown, the present invention proposes a fully automatic packaging device for shaft parts, including a support frame 1, to which a driving mechanism is fixedly connected. The driving mechanism includes a driving assembly, a second driving roller 206, and a first driving roller 204. A shaft driven by the driving assembly is placed on the second driving roller 206 and the first driving roller 204. A winding mechanism is fixedly mounted on the driving mechanism. The winding mechanism includes a reciprocating assembly and a wrapping film roll 305. One end of the wrapping film roll 305 is bonded to the shaft. The reciprocating assembly controls the wrapping film roll 305 to wrap around the shaft from different positions during the rotation of the shaft. A holding mechanism is fixedly installed on the winding mechanism, and the holding mechanism includes a pressure roller 403 and a downward pressure component. The pressure roller 403 contacts the shaft rod under the action of the downward pressure component and strengthens the connection between the winding film roll 305 and the shaft rod during the process of the shaft rod winding the winding film roll 305.

[0024] It should be noted that when the device is in use, the shaft needs to be placed between the second drive roller 206 and the first drive roller 204 first, find one end of the wrapping film roll 305, and stick the end to the shaft. Then, the second drive roller 206 and the first drive roller 204 are rotated by the driving assembly. When the second drive roller 206 and the first drive roller 204 rotate, the second drive roller 206 and the first drive roller 204 will drive the shaft to rotate due to friction. The rotation of the shaft will continuously pull the wrapping film roll 305, so that the wrapping film roll 305 is wrapped around the shaft. In the process of the wrapping film roll 305 being continuously released and wrapped by the shaft, the reciprocating assembly can also be started. The reciprocating assembly makes the wrapping film roll 305 move back and forth continuously, so that the wrapping film roll 305 can act on all positions of the shaft, wrap all positions of the shaft, and complete the packaging of the shaft.

[0025] In the process of the shaft wrapping the wrapping film roll 305, the pressure roller 403 will press down, so that the wrapping film roll 305 wrapped around the shaft will be continuously pressed by the pressure roller 403, so that the connection between the wrapping film roll 305 and the shaft is tight, ensuring the quality of automatic packaging. With the help of the downward pressing component, the pressure roller 403 can be controlled to act on shafts of different sizes, effectively avoiding excessive pressing or insufficient pressing force.

[0026] The driving assembly includes a mounting frame 201, which is fixedly connected to the support frame 1, the second driving roller 206 and the first driving roller 204 are located inside the mounting frame 201, and the mounting frame 201 is rotatably connected to the second driving roller 206 and the first driving roller 204. A first motor 202 is fixedly mounted on the support frame 1, and the power output shaft of the first motor 202 extends to the inside of the mounting frame 201. A third gear 205 is fixedly mounted on the power output shaft of the first motor 202, and the second gear 207 and the first gear 203 are meshed with the third gear 205. The second gear 207 is fixedly connected to the second driving roller 206, and the first gear 203 is fixedly connected to the first driving roller 204.

[0027] It should be noted that, when the shaft is placed on the second drive roller 206 and the first drive roller 204, the first motor 202 is started, and the power output shaft of the first motor 202 drives the third gear 205 to rotate, and the third gear 205 drives the second gear 207 and the first gear 203 to rotate, so that the second drive roller 206 and the first drive roller 204 will also rotate together. When the first drive roller 204 and the second drive roller 206 rotate, the shaft will be rotated with the help of friction. The first drive roller 204 and the second drive roller 206 are made of rubber, which has a large friction and can well drive the shaft to rotate.

[0028] The reciprocating assembly includes two mounting plates 303, which are fixedly connected to the mounting frame 201. A reciprocating screw rod 304 is rotatably installed between the two mounting plates 303. A threaded block 306 is threadedly connected to the reciprocating screw rod 304. The threaded block 306 is slidably connected to the mounting frame 201. A storage box 302 is fixedly connected to the threaded block 306. The wrapping film roll 305 is located inside the storage box 302 and is rotatably connected to the wrapping film roll 305. A second motor 301 is fixedly installed on the mounting plate 303, and a power output shaft of the second motor 301 is fixedly connected to the reciprocating screw rod 304.

[0029] It should be noted that when the shaft is driven to rotate by the first drive roller 204 and the second drive roller 206, the wrapping film roll 305 will be continuously wound, and the wrapping film roll 305 will be continuously released for wrapping around the shaft. In this process, the second motor 301 can be started, and the second motor 301 will control the reciprocating screw 304 to rotate. The reciprocating screw 304 will cause the threaded block 306 to move back and forth. The reciprocating movement of the reciprocating screw 304 will cause the storage box 302 to connect to the wrapping film roll 305 to move back and forth, so that the wrapping film roll 305 can be wrapped around different positions on the shaft, and there is no need to fix it back and forth multiple times before winding, which saves operation time.

[0030] A protective cover 401 is fixedly connected to the storage box 302 , and the wrapping film roll 305 is located inside the protective cover 401 . The wrapping film roll 305 passes through the protective cover 401 and extends to the shaft and is bonded to the shaft.

[0031] It should be noted that, since the protective cover 401 is provided, the protective cover 401 can wrap the stretch film roll 305. Since the stretch film roll 305 itself is easily damaged, if splashes fall on the stretch film roll 305 during operation, it is easy to cause damage to the stretch film roll 305. In this way, the stretch film roll 305 is easy to break when it is pulled and wound. In this way, the operator needs to re-fix the stretch film roll 305 before it can be used, which is not conducive to the continuous use of the stretch film roll 305.

[0032] The pressing mechanism also includes a protection component, which is rotatably connected to the pressing roller 403 and is connected to the pressing component mechanism. The adjusting component is fixedly connected to the pressing component.

[0033] The protective component includes a sliding box 404, which is slidingly connected to the protective cover 401. A sliding groove 416 is opened inside the sliding box 404, and an auxiliary plate 421 is slidingly connected inside the sliding groove 416. The bottom of the auxiliary plate 421 is fixedly connected to the sliding plate 414, the top of the sliding plate 414 is fixedly connected to the connecting column 420, the top of the connecting column 420 is fixedly connected to the slider 417, the top of the slider 417 is fixedly connected to the second spring 415, and the top of the second spring 415 is fixedly connected to the sliding box 404.

[0034] The protective component also includes a protective airbag 402, which is fixedly connected to the protective cover 401. An air guide tube 419 is fixedly connected to the protective airbag 402. The air guide tube 419 extends to the interior of the protective cover 401 and is fixedly connected to the sliding box 404. An extension column 418 is slidably connected to the interior of the air guide tube 419, and the extension column 418 is fixedly connected to the slider 417.

[0035] It should be noted that due to the influence of the working environment, there may be some splashing objects. Due to the function of the protective cover 401, the stretch film roll 305 can be protected from being affected. However, these splashing objects will directly hit the protective cover 401. If the impact is serious, the protective cover 401 will be deformed by the splashing objects. If the protective cover 401 is slightly vibrated, it will act on the pressing component, and the pressing component will cause the pressure roller 403 to move further downward, thereby increasing the pressure on the stretch film roll 305, causing the stretch film roll 305 to be pulled and damaged during winding, which will affect the winding of the stretch film roll 305 on the shaft. A protective airbag 402 is provided, and the protective airbag 402 is filled with The gas is released. When splashes fall onto the protective airbag 402, the protective airbag 402 will play a buffering role to reduce damage. The protective airbag 402 is affected by the splashes, which will cause the gas to act on the air guide tube 419, thereby moving the extension column 418 in the air guide tube 419 out. In this way, the extension column 418 can drive the slider 417 to move, and the slider 417 drives the sliding plate 414 to move. The sliding plate 414 will drive the pressure roller 403 to move, so that the pressure roller 403 cannot act on the wrapping film roll 305, avoiding the phenomenon of excessive pressure. When the splashes are removed, it will return to its original position under the action of the second spring 415, so that it is convenient to continue using.

[0036] The adjustment component includes a first mounting bracket 406, which is fixedly connected to the protective cover 401. The first mounting bracket 406 is fixedly connected to the second mounting bracket 411, and the second mounting bracket 411 is fixedly connected to the third motor 407. The power output shaft of the third motor 407 is fixedly connected to the fifth gear 410, and the fourth gear 409 is meshed with the fifth gear 410.

[0037] The downward pressure assembly includes a first screw 408, which is fixedly connected to the fourth gear 409, and the first screw 408 is rotatably connected to the first mounting bracket 406. A pressure plate 412 is threadedly connected to the first screw 408, and the pressure plate 412 is slidingly connected to the first mounting bracket 406. The bottom of the pressure plate 412 is fixedly connected to a first spring 413, and the bottom of the first spring 413 is fixedly connected to a connecting rod 405, and the connecting rod 405 is fixedly connected to the sliding box 404.

[0038] It should be noted that, since the size of the shaft is not the same for all, when the diameter of the shaft is small, the action of the first spring 413 will cause the slide groove 416 and the sliding box 404 to drive the pressure roller 403 to move downward. Although this can also make the pressure roller 403 contact with the shaft, the tension of the first spring 413 will be greatly reduced, and the pressure holding force of the pressure roller 403 on the shaft will also decrease, and the original effect cannot be achieved. In this way, the third motor 407 can be started, and the third motor 407 controls the fifth gear 410 to rotate, and the fifth gear 410 controls the fourth gear The wheel 409 rotates, and the fourth gear 409 controls the first screw 408 to rotate. The first screw 408 moves the pressure plate 412 downward, which can further compress the first spring 413, thereby ensuring the tension of the first spring 413. The tension of the first spring 413 is guaranteed, and the pressure of the pressure roller 403 on the shaft is also guaranteed, which can always play a good role in assisting the winding film roll 305 to be wound onto the shaft. The same is true when encountering a shaft with a large diameter. The first spring 413 can be stretched to reduce the tension of the first spring 413 and reduce the pressing force of the pressure roller 403.

[0039] The sliding box 404 is rotatably connected to a second rotating shaft 507, and a rotating plate 506 is fixedly connected to the second rotating shaft 507. A cleaning adsorption roller 501 is rotatably connected between the two rotating plates 506. A fixed box 503 is fixedly installed on the sliding box 404, and a push plate 509 is slidably connected inside the fixed box 503. The push plate 509 is connected to the fixed box 503 through a third spring 510. A rack 502 is fixedly connected to the push plate 509, and the rack 502 passes through the fixed box 503 and is slidably connected to the fixed box 503. The rack 502 is meshed with the sixth gear 505. The fixed box 503 is rotatably connected to a second screw 504, and a movable column 508 is threadedly connected to the second screw 504. The movable column 508 is slidably connected to the fixed box 503.

[0040] The cleaning roller 501 is cleaned by the cleaning roller 501 when the second rotating shaft 507 and the sliding box 404 are connected. The cleaning roller 501 is cleaned by the cleaning roller 501 when the second rotating shaft 507 and the sliding box 404 are connected. The cleaning roller 501 is cleaned by the cleaning roller 501 when the second rotating shaft 507 and the sliding box 404 are connected. The cleaning roller 501 is cleaned by the cleaning roller 501 when the second rotating shaft 507 and the sliding box 404 are connected. The cleaning roller 501 is cleaned by the cleaning roller 501 when the second rotating shaft 507 and the sliding box 404 are connected. The cleaning roller 501 is cleaned by the cleaning roller 501 when the second rotating shaft 507 and the sliding box 404 are connected.

[0041] Working principle: After the first motor 202 on the support frame 1 is started, its power output shaft drives the third gear 205 to rotate, and the third gear 205 simultaneously engages the first gear 203 and the second gear 207, thereby driving the first drive roller 204 and the second drive roller 206 to rotate synchronously in the installation frame 201.

[0042] Since the surfaces of the first driving roller 204 and the second driving roller 206 are made of rubber, the shaft placed thereon is driven to rotate by friction, thereby providing a power basis for subsequent wrapping and packaging.

[0043] The second motor 301 is mounted on the mounting plate 303 , and after starting, it drives the reciprocating screw 304 to rotate, causing the threaded block 306 to slide back and forth in the mounting frame 201 , and the threaded block 306 drives the storage box 302 and the winding film roll 305 inside to move synchronously.

[0044] One end of the wrapping film roll 305 is bonded to the shaft, and the wrapping film is pulled when the shaft rotates. At the same time, the reciprocating motion of the reciprocating screw 304 makes the wrapping film evenly cover the entire length of the shaft, realizing automatic full-size wrapping.

[0045] The third motor 407 is fixed on the second mounting bracket 411. After starting, the fifth gear 410 engages the fourth gear 409 to drive the first screw 408 to rotate, so that the pressure plate 412 moves up and down in the first mounting bracket 406, compressing or stretching the first spring 413, thereby adjusting the height of the connecting rod 405 and the sliding box 404, and realizing adaptive adjustment of the pressure force of the pressure roller 403 on the shaft.

[0046] When the diameter of the shaft is large, the third motor 407 is adjusted to keep the first spring 413 in tension, and the pressure roller 403 presses the wrapping film tightly; when the diameter is small, the spring tension is automatically compensated to ensure that the wrapping film is tightly connected to the shaft.

[0047] The protective airbag 402 is fixed on the protective cover 401. When splashing objects hit it, the gas in the airbag pushes the extension column 418 through the air guide tube 419, driving the slider 417 to slide in the slide groove 416, temporarily lifting the sliding plate 414 and the pressure roller 403 to avoid excessive pressure and breakage of the film material. After the impact, the second spring 415 resets the structure.

[0048] The cleaning adsorption roller 501 is installed on the second rotating shaft 507 of the sliding box 404 through the rotating plate 506. When the shaft rotates, the cleaning adsorption roller 501 presses the surface of the shaft under the action of the torsion spring to clean impurities; when the second screw 504 is rotated, the moving column 508 pushes the push plate 509, and the rotating plate 506 is driven to rotate through the rack 502 engaging the sixth gear 505, so that the cleaning adsorption roller 501 can be retracted without affecting the winding operation.

[0049] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
