Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to packaging equipment in the production process of artificial boards, and in particular to a stacking and rotating wrapping worktable for artificial boards. Background Technology

[0002] Currently, in the engineered wood panel manufacturing industry, finished panels need to be packaged after they come off the production line. Traditional packaging methods rely mainly on manual labor, requiring operators to walk around the stationary stacks of panels holding stretch film to wrap them. This method is labor-intensive, inefficient, and prone to problems such as loose or uneven wrapping due to the inconvenience of walking.

[0003] A search revealed that Chinese patent CN219635543U discloses a pallet packing machine. This device uses a swing arm to drive a film-releasing component to rotate around a fixed pallet stack, achieving automated film wrapping of the pallet stack's sides. However, this device has a complex structure, including precision components such as a motor, reducer, and swing arm guide rail, resulting in high manufacturing costs. Furthermore, motor failures require professional repair, leading to long maintenance cycles. Additionally, the film wrapping area is limited, only covering the sides of the pallet stack; the top surface and edges require additional manual film application, making "one-time packing" impossible. It also lacks adaptability; for pallet stacks of different widths (600-1200mm), the swing arm stroke needs adjustment, each adjustment being time-consuming, making it difficult to adapt to multi-specification board production scenarios.

[0004] Existing technologies have not fully met the packaging requirements of simple structure, low cost, full range of wrapping and high adaptability. Therefore, this utility model proposes a rotary wrapping workbench for stacking artificial boards. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, such as high labor intensity and low efficiency in manual packaging, and the complex structure, high cost, and poor adaptability of existing packaging machines, the purpose of this utility model is to provide a simple and easy-to-operate rotating wrapping workbench for stacking engineered wood panels. It can rotate the entire stack of panels, allowing operators to complete all-around wrapping operations on the top and sides of the stack from a fixed position, thereby significantly reducing labor intensity and improving packaging efficiency and quality.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A rotary wrapping workbench for stacking engineered wood panels includes:

[0008] frame;

[0009] A support platform, which is mounted on the frame;

[0010] A slewing bearing mechanism is disposed at the center of the bearing platform. The slewing bearing mechanism includes a fixed part and a rotating part. The rotating part extends upward through the bearing platform, and the upper end surface of the rotating part of the slewing bearing mechanism forms a bearing surface for supporting stacked plates.

[0011] A ring-shaped support assembly is arranged around the slewing bearing mechanism on the bearing platform. The upper surface of the ring-shaped support assembly and the bearing surface of the slewing bearing mechanism are located on the same horizontal plane, and together they support the stack of plates.

[0012] Furthermore, the slewing bearing mechanism includes:

[0013] A supporting base plate is fixed to the bearing platform;

[0014] A vertical shaft is vertically mounted on the support base plate, and the vertical shaft is provided with a first stepped surface, a second stepped surface, and a third stepped surface with progressively increasing diameter from top to bottom;

[0015] A self-aligning bearing is mounted on the first stepped surface;

[0016] The thrust bearing is mounted on the second stepped surface;

[0017] The bearing housing is fitted around the outer periphery of the self-aligning bearing and the thrust bearing;

[0018] The bearing housing upper end cover is installed on the top of the bearing housing and is fixedly connected to the bearing housing;

[0019] The lower end cover of the bearing housing is fitted onto the third stepped surface of the vertical shaft;

[0020] The upper panel is installed on the upper surface of the upper end cover of the bearing seat, and its upper surface forms the bearing surface.

[0021] Furthermore, it also includes a support plate, which is sleeved on the vertical shaft and fixed to the support base plate, and is located between the bearing seat and the support base plate, for providing auxiliary support at the bottom.

[0022] Furthermore, an oil seal is provided between the lower end cover of the bearing housing and the bearing housing to seal the lubricating grease and prevent dust.

[0023] Furthermore, the slewing bearing mechanism has six limiting blocks on its bearing surface. The six limiting blocks are arranged as follows: one on each of the left and right sides of the bearing surface, and a pair on each of the front and rear sides of the bearing surface, for positioning and preventing displacement of the stacked plates.

[0024] Furthermore, it also includes a booster mechanism, said booster mechanism comprising:

[0025] Multiple support rods, one end of each support rod is wrapped around and fixed to the outer peripheral edge of the bearing surface, and the other end extends outward radially;

[0026] An annular outer frame is fixedly connected to the outer ends of all the support rods;

[0027] Multiple push rods are arranged at circumferential intervals along the annular outer frame.

[0028] Furthermore, it also includes multiple casters, which are installed at the bottom of the frame and arranged in a circular array around the slewing bearing mechanism to facilitate the movement and positioning of the entire worktable.

[0029] Furthermore, the number of casters is twelve to provide stable and balanced support.

[0030] Furthermore, the support platform is a circular plate with flattened top and bottom ends, which provides structural stability and saves space.

[0031] Beneficial effects

[0032] This invention combines a central slewing bearing mechanism with a fixed outer ring support assembly, enabling heavy stacks of boards to be easily driven to rotate. Operators do not need to move around the stack; they can complete continuous and tight wrapping of the top, edges, and sides of the rotating stack from a fixed position, significantly reducing labor intensity and improving work efficiency and consistency. The slewing bearing mechanism employs a combination of self-aligning bearings and thrust bearings, supplemented by a stepped shaft structure. This effectively withstands combined radial and axial loads and automatically compensates for installation errors, ensuring the stability and reliability of the stack rotation and extending the equipment's service life. By incorporating limit blocks and a pusher mechanism, the limit blocks prevent the stack from slipping or tipping during rotation; the pusher mechanism, by increasing the lever arm, allows operators to rotate the stack with less force, further reducing operational difficulty. The overall structure is simple and reasonable, with low manufacturing costs and flexible movement, making it highly suitable for the actual packaging processes in wood-based panel manufacturing enterprises and possessing significant promotional value.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0038] Example 1

[0039] like Figure 1 and Figure 2 As shown, the present invention provides a stacking and rotating wrapping workbench for artificial boards, which mainly includes a frame (not fully shown in the figure), a bearing plate 1, a slewing support mechanism 2, a ring support assembly 3, and multiple casters 8.

[0040] The support platform 1 is preferably a circular plate with flattened top and bottom ends, and is fixedly installed on the frame. The slewing bearing mechanism 2 is located at the geometric center of the support platform 1. The annular support assembly 3 is composed of multiple arc-shaped support bars or an integral ring structure, and is fixedly installed on the support platform 1 around the slewing bearing mechanism 2 with its center around it. Its upper surface is strictly kept at the same horizontal level as the bearing surface of the slewing bearing mechanism 2, so as to jointly and stably support the stack of boards to be packaged.

[0041] Specifically, the slewing bearing mechanism 2 includes a support base plate 21, a vertical shaft 22, a self-aligning bearing 23, a thrust bearing 24, a bearing housing 25, an upper end cover 26 of the bearing housing, a lower end cover 27 of the bearing housing, a top panel 28, a support plate 29, and an oil seal 30. The support base plate 21 is fixed to the center of the support platform 1 by bolts. The vertical shaft 22 is vertically mounted on the support base plate 21, and its shaft body is machined with first, second, and third stepped surfaces with progressively increasing diameters from top to bottom. The self-aligning bearing 23 is mounted on the first stepped surface and is mainly used to bear radial loads and has a certain self-aligning function. The thrust bearing 24 is mounted on the second stepped surface and is mainly used to bear the axial pressure generated by the stacking of plates. The bearing housing 25, as the core rotating component, is fitted onto the outer rings of the self-aligning bearing 23 and the thrust bearing 24, combining the two into one unit. The upper end cover 26 of the bearing housing is fastened to the top of the bearing housing 25 by bolts. The upper panel 28 is mounted on the upper surface of the bearing housing upper end cover 26, and its flat upper surface forms the bearing surface for placing the stacked plates. The support plate 29 is sleeved on the vertical shaft 22 and fixed on the support base plate 21, providing auxiliary support for the bottom of the bearing housing 25 and enhancing structural stability. The lower end cover 27 of the bearing housing is sleeved on the third stepped surface of the vertical shaft 22, and an oil seal 30 is installed between it and the lower end of the bearing housing 25 to effectively prevent the leakage of grease inside the bearing and block the intrusion of external impurities.

[0042] Multiple casters 8 are mounted on the bottom of the frame and are evenly distributed in a circular array around the slewing bearing mechanism 2. In this embodiment, twelve casters 8 are preferably provided to ensure that the worktable moves flexibly and is stably supported.

[0043] Work Process: The stack of boards to be packaged is hoisted or transported to the workbench, with its center bottom placed on the bearing surface (upper panel 28) of the slewing bearing mechanism 2, and its periphery supported by the annular support assembly 3. The operator stands in a fixed position next to the workbench, holding the stretch film. By manually pushing the stack of boards slightly, the stack causes the upper panel 28, bearing seat 25, and other rotating components to rotate relative to the fixed vertical axis 22 and the bearing platform 1. The operator can then apply the stretch film to the rotating stack from the fixed position, completing the wrapping operation around the entire stack.

[0044] Example 2

[0045] This embodiment, based on the basic structure of embodiment 1, further adds limiting and boosting functions, such as... Figure 3 As shown.

[0046] Six limiting blocks 4 are bolted to the bearing surface (upper surface of upper panel 28) of the slewing bearing mechanism 2. They are arranged as follows: one limiting block is placed on each of the left and right sides of the bearing surface, and a pair (two) of limiting blocks are placed on each of the front and rear sides of the bearing surface. These limiting blocks 4 together form a positioning area, which can effectively restrict the horizontal movement or tipping of the stacked plates placed within it during rotation, improving operational safety.

[0047] Meanwhile, this embodiment adds a booster mechanism. This mechanism includes multiple support rods 5, an annular outer frame 6, and multiple push rods 7. The inner ends of the multiple support rods 5 surround and are fixed to the outer peripheral edge of the top plate 28 (e.g., by welding or bolting), and extend outward in a radial pattern. The annular outer frame 6 is fixedly connected to the outer ends of all support rods 5 by welding or bolting. The multiple push rods 7 are evenly spaced along the circumference of the annular outer frame 6. When it is necessary to rotate the stack, the operator can push any push rod 7. Since the lever arm of the push rod 7 from the center of rotation is much larger than the lever arm of directly pushing the edge of the stack, the entire stack can be rotated with very little effort, further optimizing the operating experience.

[0048] Work process:

[0049] 1. Stacking and placement: The artificial boards to be packaged are stacked and transported to the workbench by forklift or overhead crane, so that the bottom center of the stack is placed on the bearing surface of the upper panel 28, the bottom edge of the stack is in contact with the annular support component 3, and the stack is positioned in close contact with the limiting block 4 around its perimeter.

[0050] 2. Equipment positioning: Push the workbench to the packaging station, depress the brake device of the caster wheel 8, and fix the position of the workbench;

[0051] 3. Wrapping operation: The operator stands next to the workbench, holds the wrapping film roll, and attaches the film end to the bottom side of the stack; pushes the push rod 7, which drives the upper panel 28 and bearing seat 25 to rotate around the vertical axis 22 through the push mechanism; the stack rotates synchronously with the rotating parts, and the operator keeps the film roll tension stable and slowly moves the film roll along the stack height direction to achieve continuous wrapping of the top, sides and edges of the stack, reducing the packaging time of a single stack to 5-8 minutes;

[0052] 4. Work completed: After the wrapping is finished, cut the wrapping film and stick it in place. Release the brakes on the casters, push the worktable to the next station, and repeat the above steps.

[0053] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
