Description

Technical Field

[0001] This utility model relates to the field of packaging technology for automotive parts, specifically to a rotating storage and packaging tray device for steering knuckles. Background Technology

[0002] Traditional packaging methods for steering knuckles have many shortcomings. In the past, disposable corrugated cardboard, pearl cotton, and bubble wrap were commonly used for simple isolation and protection. However, these materials are difficult to assemble into a regular shape for irregularly shaped steering knuckles. During transportation, the steering knuckles are difficult to secure, making them prone to rolling and impacts, posing safety hazards to production and transportation. For example, during transportation, it is not uncommon for steering knuckles to wobble and collide, resulting in scratches and damage to the surface, affecting product quality.

[0003] Existing packaging structures, such as placing the steering knuckle in a separate rectangular space within the box, result in a large amount of redundant space due to the mismatch between the steering knuckle's structural shape and the rectangular space. This limits the number of steering knuckles that can be packaged within the box, greatly wasting transportation space and increasing transportation costs. Other methods use molded pallets such as blister packs, but because the steering knuckle's structure is not standardized and contains assembly slots and lacks a fixed surface, it is difficult to effectively protect the product.

[0004] To address the aforementioned technical issues, patent publication number CN115804919A describes a recyclable steering knuckle packaging shell. This primarily focuses on the structural design of the shell, improving its strength and recyclability through the inclusion of a base plate, side plates, and fixing blocks. However, it does not address the automation of the packaging process or the effective transport and control of packaging materials. In summary, existing technologies have significant shortcomings in automated steering knuckle packaging, particularly in achieving efficient and precise packaging using specific pallet structures, necessitating urgent innovation and improvement.

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a steering knuckle rotation and storage packaging tray device, which has the advantages of automated and rapid packaging and improved packaging material utilization. It solves the problems of cumbersome manual operation, difficulty in adapting to the complex shape of steering knuckles, and serious waste of packaging materials in traditional steering knuckle packaging methods.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a device for rotating and storing a packaging tray for a steering knuckle, comprising a tray and a steering knuckle, wherein a rotating ring is provided on the tray, and fixed support columns and an outer ring are respectively provided inside and outside the ring, and the tray is provided with:

[0009] A packaging assembly, comprising a first rotating shaft, a second rotating shaft, and a packaging body, wherein the first rotating shaft is rotatably mounted on an outer ring, the second rotating shaft is fixedly mounted on a circular ring, and one end of the packaging body is connected to the second rotating shaft and the other end is connected to the first rotating shaft;

[0010] A rotating assembly is fixedly disposed between the tray and the second rotating shaft, and is used to drive one end of the packaging body to wrap around the steering knuckle;

[0011] A clamping assembly is disposed on the support column for clamping and fixing the steering knuckle.

[0012] Preferably, the rotating assembly includes a driving gear fixedly mounted on a ring and a driven gear located below the first rotating shaft. The driving gear is driven by a motor, and the driving gear meshes with the driven gear.

[0013] Preferably, the second rotating shaft is provided with several pointed blocks for covering the packaging body.

[0014] Preferably, a fixing frame is provided between the first rotating shaft and the second rotating shaft, and the fixing frame is fixedly mounted on the outer ring of the tray, through which the packaging body passes.

[0015] Preferably, the clamping assembly includes a pneumatic pump, a conduit, a clamp, and an airbag, wherein the pneumatic pump is connected to the airbag via the conduit, and the airbag is located in a groove of the clamp.

[0016] Preferably, the drive gear is provided with:

[0017] A hole for inserting a support post of a clamping assembly, wherein the drive gear is rotatably connected to the support post;

[0018] A protrusion is fixedly disposed on the side of the hole away from the packaging component. The protrusion is rotatably connected to the outer ring of the tray to prevent the drive gear from disengaging from the outer ring when it rotates.

[0019] Preferably, the drive gear is fixedly connected to the second rotating shaft, and when the drive gear rotates, it drives the second rotating shaft to make circular motion around the steering knuckle.

[0020] Preferably, when the motor drives the driving gear to rotate, the driven gear drives the first rotating shaft to rotate, so that the packaging body can detach from the first rotating shaft.

[0021] Preferably, the pointed block is a triangular protrusion. When the second rotating shaft completes one revolution, the pointed block on the surface of the second rotating shaft comes into contact with the packaging body to be used. The packaging body to be used is located between the fixing frame and the packaging body that has been covered with the steering knuckle.

[0022] Preferably, the discharge speed of the packaging body is less than or equal to the winding speed of the packaging body, so that the packaging body remains taut throughout the packaging process.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, this utility model provides a device for rotating and storing packaging trays for steering knuckles, which has the following advantages:

[0025] 1. The steering knuckle rotating storage and packaging pallet device is designed with the pallet divided into three parts. The drive gear and the second rotating shaft on the ring rotate to drive the packaging body to wrap around the steering knuckle. At the same time, the first rotating shaft on the outer ring supplies the packaging body. The mode of only rotating components moving greatly reduces the overall motion complexity of the device, effectively reduces the probability of failure, and improves the reliability and service life of the equipment.

[0026] 2. This device for rotating and storing packaging trays for steering knuckles, by setting a rotating component, namely a driving gear on the ring and a driven gear on the outer ring, sets the discharge speed of the packaging body to be less than or equal to the winding speed of the packaging body, so as to achieve the effect of keeping the packaging body taut at all times, improving the sealing effect between the packaging body and the steering knuckle, enhancing the protective performance, accelerating the working efficiency of the sharp block on the second rotating shaft to divide the packaging body, and effectively shortening the packaging cycle of a single steering knuckle.

[0027] 3. This steering knuckle rotation and storage packaging tray device, by setting up packaging components, uses a motor to drive a drive gear, which directly drives a second rotating shaft to perform circular motion around the steering knuckle. It eliminates the need to pre-set the shape of the steering knuckle's outer packaging, making one device suitable for steering knuckles of different shapes on the market. This effectively avoids the cumbersome process of frequently changing the outer packaging due to differences in steering knuckle shape, significantly improving packaging efficiency and reducing labor and time costs.

[0042] Example 1:

[0043] This embodiment provides a device for rotating and storing packaging pallets for steering knuckles, which has the following technical features.

[0044] Please see Figure 1-9 A device for rotating and storing a packaging pallet for a steering knuckle includes a pallet 1 and a steering knuckle 2. The pallet 1 has a rotating ring, and fixed support columns 56 are respectively installed inside and outside the ring. The pallet 1 also includes:

[0045] Packaging component 3 includes a first rotating shaft 31, a second rotating shaft 34, and a packaging body 32. The first rotating shaft 31 is rotatably mounted on the outer ring, the second rotating shaft 34 is fixedly mounted on the ring, and one end of the packaging body 32 is connected to the second rotating shaft 34 and the other end is connected to the first rotating shaft 31.

[0046] The rotating component 4 is fixedly disposed between the tray 1 and the second rotating shaft 34, and is used to drive one end of the packaging body 32 to wrap around the steering knuckle 2;

[0047] The clamping assembly 5 is mounted on the support column 56 and is used to clamp and fix the steering knuckle 2.

[0048] It should be noted that:

[0049] The packaging body 32 is one of foam plastic, crepe paper or sponge sheet that has a cushioning effect, is easy to cut, and can be rolled up. The width of the packaging body 32 is less than the height of the first rotating shaft 31 and the second rotating shaft 34.

[0050] A non-through hole is provided on the outer ring of the tray 1, and one end of the first rotating shaft 31 is inserted into the hole, and the first rotating shaft 31 is rotatably connected to the hole;

[0051] The packaging body 32 is connected to the first rotating shaft 31 and the second rotating shaft 34 by a sleeve connection. One end of the packaging body 32 is rolled up and sleeved on the first rotating shaft 31, and the other end is sleeved on the pointed block of the second rotating shaft 34. Anti-slip texture is provided at the sleeve connection to prevent the packaging body from falling off during rotation.

[0052] The motor is fixed to the clamping assembly by a motor mount, and the motor output shaft is connected to the drive gear 42 by a key to ensure effective power transmission;

[0053] The side of clamp 53 closest to steering knuckle 2 is made of soft, non-slip rubber to prevent damage to the surface of steering knuckle 2;

[0054] The air pump 51 is tightly connected to the conduit 52 via an air pipe connector. The end of the airbag 54 near the conduit 52 is connected to the support column 56 with glue. The side of the airbag 54 that is not attached to the slide groove 55 and not attached to the clamp 53 is a rigid structure, which restricts the airbag from inflating only towards the clamp 53, thereby pushing the clamp 53 to slide towards the steering knuckle 2.

[0055] In an optional embodiment, the rotating assembly 4 includes a driving gear 42 fixedly mounted on a ring and a driven gear 41 located below the first rotating shaft 31. The driving gear 42 is driven by a motor and meshes with the driven gear 41.

[0056] In an optional embodiment, the second rotating shaft 34 is provided with a plurality of pointed blocks 341 for covering the packaging body 32.

[0057] It should be noted that the pointed block 341 is fixed to the second rotating shaft 34 by welding or bolting. During the rotation of the second rotating shaft 34, it can drive the packaging body 32 to rotate around the steering knuckle 2.

[0058] In an optional embodiment, a fixing frame 33 is provided between the first rotating shaft 31 and the second rotating shaft 34. The fixing frame 33 is fixedly mounted on the outer ring of the tray 1, and the packaging body 32 passes through the gap of the fixing frame 33.

[0059] It should be noted that the fixing frame 33 is fixed to the outer ring of the tray 1 by welding or bolt connection. The gap width of the fixing frame 33 is slightly larger than the thickness of the packaging body 32, which can ensure that the packaging body 32 can pass through smoothly and limit its shaking during the transmission process, ensuring that the packaging body 32 moves along the predetermined path.

[0060] In an optional embodiment, the clamping assembly 5 includes a pneumatic pump 51, a conduit 52, a clamp 53, and an airbag 54. The pneumatic pump 51 is connected to the airbag 54 through the conduit 52, and the airbag 54 is located in the groove 55 of the clamp 53.

[0061] It should be noted that when the air pump 51 is turned on, the air pump 51 starts to work, and delivers compressed air to the air bag 54 through the conduit 52; the air bag 54 expands in the slide groove 55 under the action of air pressure, and its expansion force pushes the clamp 53 to slide along the slide groove 55 towards the steering knuckle 2 until the clamp 53 firmly clamps the steering knuckle 2; the clamping force of the clamp 53 is controlled by adjusting the output air pressure of the air pump 51.

[0062] In an optional embodiment, the drive gear 42 is provided with:

[0063] Hole 421 is used to insert the support column 56 of the clamping assembly 5, and the drive gear 42 is rotatably connected to the support column 56;

[0064] A protrusion 422 is fixedly disposed on the side of the hole 421 away from the packaging component 3. The protrusion 422 is rotatably connected to the outer ring of the tray 1 to prevent the drive gear (42) from disengaging from the outer ring when it rotates.

[0065] It should be noted that after the support column 56 is inserted into the hole 421, a limit block is provided on the support column 56, and the limit block on the support column 56 is rotatably connected to the drive gear 42.

[0066] In an optional embodiment, the drive gear 42 is fixedly connected to the second rotating shaft 34, and when the drive gear 42 rotates, it drives the second rotating shaft 34 to make a circular motion around the steering knuckle 2.

[0067] It should be noted that the ring, the drive gear 42, and the second rotating shaft 34 are welded together to ensure that the rotational motion of the drive gear 42 can be transmitted to the second rotating shaft 34. When the motor drives the drive gear 42 to rotate, the second rotating shaft 34, driven by it, moves in a circle around the steering knuckle 2 with the center of the tray 1 as the center, thereby realizing the packaging body 32 surrounding the steering knuckle 2.

[0068] In an optional embodiment, when the motor drives the drive gear 42 to rotate, the driven gear 41 drives the first rotating shaft 31 to rotate, so that the packaging body 32 can be detached from the first rotating shaft 31 and supplied to the second rotating shaft 34 for packaging the steering knuckle 2.

[0069] It should be noted that after the motor starts, the drive gear 42 begins to rotate under the drive of the motor. Since the drive gear 42 meshes with the driven gear 41, the driven gear 41 rotates accordingly, thereby driving the first rotating shaft 31 to rotate. The first rotating shaft 31 rotates in the hole opened on the outer ring of the tray 1, and does not take the center of the tray 1 as the center. During the rotation of the first rotating shaft 31, there is friction between its surface and the packaging body 32, which causes the packaging body 32 to be released and detached from the first rotating shaft 31, so as to provide packaging material for the second rotating shaft 34 to subsequently package around the steering knuckle 2.

[0070] In an optional embodiment, the pointed block 341 is a triangular protrusion. When the second rotating shaft 34 completes one revolution, the pointed block 341 on the surface of the second rotating shaft 34 comes into contact with the unused packaging body 32, which is located between the fixing frame 33 and the packaging body 32 that has been covered with the steering knuckle 2.

[0071] It should be noted that when the second rotating shaft 34 completes one wrapping of the steering knuckle 2, the triangular protruding tip 341 first contacts the unused package 32 located between the fixing frame 33 and the package 32 already wrapped on the steering knuckle 2; as the second rotating shaft 34 continues to rotate, under the pressure generated by the continuous rotation of the second rotating shaft 34, the tip 341 will penetrate the unused package 32 to form a cutting separation line, realizing the separation of the used package 32 from the unused package 32, and preparing for the next wrapping of the steering knuckle 2.

[0072] It should be noted that the ring and outer ring of tray 1 are connected as a whole by a support structure. That is, the support column 56 located between the ring of tray 1 and the outer ring of tray 1 is connected by the support structure (the support structure is one of the support column, triangular bracket, or I-beam) to ensure that there is no displacement or shaking during the operation of the device. The power output of the motor is only transmitted to the drive gear 42 on the ring, while the ring and outer ring are stationary.

[0073] In an optional embodiment, the discharge speed of the packaging body 32 is less than or equal to the winding speed of the packaging body 32, so that the packaging body 32 remains taut throughout the packaging process.

[0074] It should be noted that the discharge speed of the packaging body 32 refers to the speed at which the packaging body 32 leaves the first rotating shaft 31, and the winding speed of the packaging body 32 refers to the speed at which the packaging body 32 is wound around the steering knuckle 2.

[0075] Working principle:

[0076] Place the steering knuckle 2 in the pre-reserved gap at the upper middle of the clamping assembly 5, and start the air pump 51. Compressed air is delivered to the airbag 54 through the air pipe connector and conduit 52. The airbag 54 inflates in the slide groove 55, and its expansion force pushes the clamp 53 to slide along the slide groove 55 towards the steering knuckle 2 until the clamping surface of the clamp 53 fixes the steering knuckle 2, completing the preparation for fixing the steering knuckle. One end of the packaging body 32 is rolled up and fitted onto the first rotating shaft 31, and the other end is fitted by the worker from the first rotating shaft 31 through the gap of the fixing frame 33 onto the pointed block 341 of the second rotating shaft 34.

[0077] When the motor is started, the output shaft drives the drive gear 42 to rotate via a key connection. Since the drive gear 42 meshes with the driven gear 41 located below the first rotating shaft 31, the driven gear 41 rotates accordingly, thereby driving the first rotating shaft 31 to rotate within the hole on the outer ring of the tray 1 (with the central axis of the first rotating shaft 31 as the center). When the first rotating shaft 31 rotates, the packaging body 32 detaches from the first rotating shaft 31.

[0078] When the drive gear 42 rotates, it drives the second rotating shaft 34 to make a circular motion around the steering knuckle 2 with the center of the tray 1 as the center. At this time, the packaging body 32, which is fitted on the tip block 341 of the second rotating shaft 34, wraps around the steering knuckle 2 as the second rotating shaft 34 rotates.

[0079] After the second rotating shaft 34 completes one revolution around the steering knuckle 2, the triangular protrusion 341 on the second rotating shaft 34 first contacts the packaging body 32 between the second rotating shaft 34 and the fixing frame 33. Under the pressure generated by the continuous rotation of the second rotating shaft 34, it punctures the packaging body 32, realizing the separation of the packaging body, and preparing for the next packaging of the steering knuckle 2.

[0080] In summary, this steering knuckle rotating storage and packaging pallet device divides the pallet 1 into three parts, allowing the drive gear 42 on the ring and the second rotating shaft 34 to rotate, driving the packaging body 32 to wrap around the steering knuckle 2. Simultaneously, the first rotating shaft 31 on the outer ring supplies the packaging body 32. The mode of movement of only the rotating component 4 greatly reduces the overall motion complexity of the device, effectively reducing the probability of failure and improving the reliability and service life of the equipment.

[0081] This device for rotating and storing packaging trays for steering knuckles, by setting a rotating component 4, namely a driving gear 42 on the ring and a driven gear 41 on the outer ring, and by setting the discharge speed of the packaging body 32 to be less than or equal to the winding speed of the packaging body 32, achieves the effect of keeping the packaging body 32 taut at all times, improves the sealing effect between the packaging body 32 and the steering knuckle 2, enhances the protective performance, speeds up the working efficiency of the sharp block 341 on the second rotating shaft 34 in dividing the packaging body 32, and effectively shortens the packaging cycle of a single steering knuckle 2.

[0082] This device for rotating and storing packaging trays for steering knuckles, through the setting of packaging component 3, uses a motor to drive a drive gear 42, which directly drives a second rotating shaft 34 to perform circular motion around the steering knuckle 2. It eliminates the need to pre-set the outer packaging shape of the steering knuckle 2, making one device applicable to steering knuckle 2s of different shapes on the market. This effectively avoids the cumbersome process of frequently changing the outer packaging due to differences in the shape of the steering knuckle 2, significantly improving packaging efficiency and reducing labor and time costs.
