Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a resistor box packaging platform. Background Technology

[0002] As commonly used electronic components, resistor boxes require packaging after production for convenient transportation and storage. Currently, the packaging of resistor boxes mainly relies on manual operation, commonly employing manual handling and box packing. However, this traditional packaging method has many shortcomings, severely restricting production efficiency and packaging quality.

[0003] Traditional resistance box packaging methods, involving manual handling and packing, are slow and inefficient, especially when dealing with large-volume shipments. This makes it difficult to meet production rhythm requirements and hinders overall production efficiency. The weight of the resistance boxes themselves, combined with prolonged and repetitive handling and packing, significantly increases worker fatigue and negatively impacts their long-term health. Furthermore, manual packing is susceptible to quality issues due to operator skill, leading to improper packing and inadequate protective measures, thus reducing packaging quality consistency. Improper packing can also damage resistance boxes during transport, resulting in economic losses.

[0004] For example, a rotatable packing workbench with publication number "CN108528790A" features casters for easy movement, but its stability is crucial during packing operations, especially when packing precision instruments like resistor boxes. Casters can cause the workbench to wobble during rotation or operation, affecting packing accuracy and potentially causing resistor boxes to slip or be damaged, posing a safety hazard. One rotatable packing workbench description only mentions a "rotating shaft" driving the rotation, but lacks sufficient description of the shaft's support structure and the stability of the rotation mechanism. In practical applications, insufficient support for the rotation mechanism can lead to unstable or jammed rotation, affecting operational smoothness and efficiency. The comparative document only describes a "base" as its support structure, a relatively simple structure that may not provide sufficient load-bearing capacity and stability, especially when packing large or heavy resistor boxes. Weak load-bearing capacity could compromise the workbench's stability and safety.

[0005] Therefore, there is a need for a resistance box packing table that is stable in rotation and packing, has a strong load-bearing capacity, can improve the packing efficiency and quality of resistance boxes, reduce the labor intensity of workers, and is more convenient to operate. Utility Model Content

[0006] In order to overcome the technical defects of unstable rotating mechanism and insufficient load-bearing capacity in the prior art, this utility model provides a resistor box packaging platform.

[0007] To solve the above problems, this utility model is implemented according to the following technical solution:

[0008] This utility model discloses a resistor box packaging platform, comprising: a support assembly, a rotating assembly, and a limit adjustment assembly. The support assembly includes an upper wooden board, an upper support plate, a lower support plate, and a lower wooden board arranged sequentially from top to bottom. The rotating assembly is disposed between the upper and lower support plates and is used to support and drive the turntable to rotate. The rotating assembly includes a turntable, a central shaft, and double bearings. The turntable has double bearings symmetrically embedded at its upper and lower ends, and bearing seats are respectively provided at the upper and lower ends of the turntable. The double bearings are installed in the bearing seats, and the inner rings of the double bearings are clearance-fitted with the central shaft. The upper support plate, the turntable, and the lower support plate all have coaxial center holes. The central shaft passes through the center holes, and both ends are fixed by axial fastening assemblies, thus fixing the rotating assembly as a whole between the upper and lower support plates. The limit adjustment assembly is used to fix the resistor box to the support assembly. The limit adjustment assembly includes several limit strips and an adjustment groove opened on the upper support plate. The limit strips have sliding connecting parts that are slidably connected to the adjustment groove.

[0009] Preferably, the axial fastening assembly includes:

[0010] First nut assembly; the first nut assembly includes a first nut, a first spring washer, and a first flat washer arranged sequentially from top to bottom;

[0011] The second nut assembly includes a second nut, a second spring washer, and a second flat washer arranged sequentially from bottom to top.

[0012] The central shaft has external threads at both its upper and lower ends. The first nut assembly and the second nut assembly are respectively fitted onto the external threads at the upper and lower ends of the central shaft and are fixedly connected to the upper support plate and the lower support plate.

[0013] Preferably, the dual bearings are deep groove ball bearings.

[0014] Preferably, the turntable has a disc-shaped structure with grooves on its surface for placing the resistor box.

[0015] Preferably, both the upper and lower wooden boards are circular board structures.

[0016] Preferably, both the upper support plate and the lower support plate are rectangular plate structures and are made of metal.

[0017] Preferably, the upper wooden board, upper support plate, lower support plate, and lower wooden board are all provided with threaded connections. The upper support plate is located below and aligned with the upper wooden board and is fixedly connected by screws. The lower support plate is located above and aligned with the lower wooden board and is fixedly connected by screws. The bottom of the lower wooden board is fixed to the ground by bolts.

[0018] Preferably, the adjusting groove is an elongated through hole.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] In this invention, the support assembly combines upper and lower support plates and wooden boards, and the central shaft and double bearing structure of the rotating assembly ensure the stability of the turntable's rotation. This prevents the packing table from tipping over or shaking during operation, protecting the safety of operators and resistor boxes. The rotating assembly allows the worktable to rotate 360 ​​degrees, enabling workers to easily access all sides of the resistor boxes for packing operations without frequent movement or circling. This greatly simplifies the packing process, saves workers' time and effort, and significantly improves packing efficiency. The limit adjustment assembly, through a sliding adjustable limit strip, allows for flexible adjustment of the limit range according to resistor boxes of different sizes. This makes the packing table suitable for packing resistor boxes of various specifications, reducing the hassle of changing equipment due to different product sizes. Attached Figure Description

Detailed Implementation

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] like Figures 1-5 As shown, a resistor box packaging platform of the present invention includes: a support component 10, a rotation component 20 and a limit adjustment component 30. The support component includes an upper wooden board 13, an upper support plate 11, a lower support plate 12 and a lower wooden board 14 arranged from top to bottom.

[0030] The rotating assembly 20 is disposed between the upper support plate 11 and the lower support plate 12 to support and drive the turntable to rotate. The rotating assembly 20 includes a turntable 21, a central shaft 22 and double bearings 23. The turntable 21 has double bearings 23 symmetrically embedded at its upper and lower ends. The upper and lower ends of the turntable 21 are respectively provided with bearing seats. The double bearings 23 are installed in the bearing seats. The inner ring of the double bearings 23 is clearance-fitted with the central shaft 22. The upper support plate 11, the turntable 21 and the lower support plate 12 are all provided with coaxial central holes. The central shaft 22 passes through the central holes and is fixed at both ends by axial fastening assemblies 24, thus fixing the rotating assembly as a whole between the upper and lower support plates.

[0031] The limit adjustment assembly is used to fix the resistor box to the support assembly 10. The limit adjustment assembly 30 includes a plurality of limit strips 31 and an adjustment groove 32 opened on the upper support plate 11. The limit strips 31 are provided with a sliding connection part 33 and are slidably connected to the adjustment groove 32.

[0032] To further enhance overall stability, in this embodiment, the upper support plate 11 is preferably fixed to the upper wooden board 13 by using multiple countersunk self-tapping screws. These screws are screwed in from above the upper wooden board 13, passing through the board and then into the pre-drilled holes in the upper support plate 11. The heads of the countersunk screws are recessed into the surface of the wooden board to ensure the flatness of the workbench surface. The number and distribution of the screws should ensure a firm connection; it is recommended to have at least four screws on each side.

[0033] Fixing the lower support plate 12 and the lower wooden board 14: The connection method is similar to that of the upper support plate 11 and the upper wooden board 13, and countersunk self-tapping screws are also used for fixing.

[0034] Fixing the lower wooden board 14 to the ground: Multiple bolt holes are pre-drilled at the bottom of the lower wooden board 14. The lower wooden board 14 is then securely fixed to the ground using expansion bolts or anchor bolts. The specific specifications and number of bolts should be determined based on the weight of the packing platform and the ground conditions of the usage environment to ensure the stability of the packing platform during use and prevent tipping or displacement.

[0035] Support assembly 10: Serving as a stable base for the packing table, the support assembly consists of an upper support plate 11, a lower support plate 12, an upper wooden board 13, and a lower wooden board 14. The upper support plate 11 and the upper wooden board 13 form the upper load-bearing platform; the lower support plate 12 and the lower wooden board 14 form the lower support structure. The bottom of the lower wooden board 14 is also firmly fixed to the ground with bolts to ensure that the packing table will not shift or tip over during operation. The shape of the support plate can be determined according to design requirements; for example, it can be processed into a square steel plate with dimensions similar to the wooden board, and a through hole is pre-drilled in the center for installing the rotating assembly.

[0036] Rotating assembly 20: This assembly is the core component for realizing the rotation of the worktable, including a turntable 21, a central shaft 22, and double bearings 23. The double bearings 23 are symmetrically embedded at both ends of the turntable 21, and a clearance fit is used between the double bearings 23 and the central shaft 22 to ensure that the turntable can rotate flexibly and smoothly. Axial fasteners 24 are provided at both ends of the central shaft 22, passing through pre-drilled holes in the center of the upper support plate 11, the turntable 21, and the lower support plate 12, tightly connecting the rotating assembly and the support assembly to form a rotatable worktable.

[0037] One installation method is described in this embodiment:

[0038] Bearing installation: Press the two double bearings 23 into the bearing housings at the upper and lower ends of the turntable 21, respectively. The dimensions of the bearing housings should be precisely matched with the outer diameter of the bearings to ensure the stability and coaxiality of the bearing installation.

[0039] Central shaft insertion: The central shaft 22 is vertically inserted through the center hole of the upper support plate 11, the inner ring of the upper bearing 23, the center hole of the turntable 21, the inner ring of the lower bearing 23, and the center hole of the lower support plate 12.

[0040] Axial fastening: Axial fastening components 24 are installed at both the upper and lower ends of the central shaft 22. First, elastic retaining rings are installed at both ends of the central shaft, and then lock nuts are screwed into and tightened at the shaft ends. The function of the axial fastening components 24 is to fix the central shaft 22 in the axial position to prevent its axial movement, and at the same time support the turntable 21 between the upper and lower support plates to form a rotatable structure.

[0041] Clearance adjustment: During assembly, attention should be paid to adjusting the clearance between the inner ring of the double bearing 23 and the central shaft 22 to ensure smooth and flexible rotation of the turntable 21 and avoid it being too tight or too loose.

[0042] Limit adjustment assembly 30: This assembly is used for limit adjustment according to the size of the resistor box, and consists of several limit strips 31 and an adjustment groove 32 formed on the upper support plate 11. The limit strips 31 are provided with sliding connection parts 33, which form a sliding connection with the adjustment groove 32, allowing the limit strips to slide within the adjustment groove, thereby adjusting the position of the limit strips to adapt to resistor boxes of different sizes and realize the limit function.

[0043] In this embodiment, a method for adjusting and assembling a limit adjustment component is described:

[0044] Slide groove machining: An annular elongated adjustment slide groove 32 is machined on the edge of the upper support plate 11 using milling or wire cutting processes. The position and size of the slide groove should ensure that the limit strip 31 can effectively match the size of the resistor box after installation.

[0045] Install the retaining strip: Insert the sliding connection part 33 of the retaining strip 31 into the adjusting groove 32 so that it can slide along the groove.

[0046] Limit adjustment: Based on the actual packaging requirements of the resistor box, manually slide the limit strip 31 in the adjustment groove 32 to adjust the spacing between the limit strips 31, thereby setting the rotation angle range of the turntable 21. After adjustment, tighten the fastening screws on the limit strip 31 to fix the limit strip in the current position, thus limiting the rotation angle of the turntable.

[0047] Optionally, springs or other components can be installed in the limit adjustment assembly for easy locking.

[0048] Quantity configuration: The number of limit strips 31 can be configured according to actual needs. 2-4 limit strips can be configured to meet the limit requirements of different resistor box specifications.

[0049] Preferably, the axial fastening assembly 24 includes a first nut assembly 25 and a second nut assembly 26;

[0050] The first nut assembly 25 includes a first nut 251, a first spring washer 252 and a first flat washer 253 arranged sequentially from top to bottom;

[0051] The second nut assembly 26 includes a second nut 261, a second spring washer 262, and a second flat washer 263 arranged sequentially from bottom to top;

[0052] The central shaft 22 has external threads at both its upper and lower ends. The first nut assembly 25 and the second nut assembly 26 are respectively fitted with the external threads at the upper and lower ends of the central shaft and are fixedly connected to the upper support plate 13 and the lower support plate 14.

[0053] The axial fastening assembly is designed to securely connect the central shaft to the support assembly and the turntable via a threaded connection. In this embodiment, the axial fastening assembly specifically consists of a first nut assembly 25 and a second nut assembly 26.

[0054] The first nut assembly 25 is used to fix the upper end of the central shaft. Its structure, from top to bottom, consists of a first nut 251, a first spring washer 252, and a first flat washer 253. The first flat washer 253 increases the contact area and protects the surface of the upper support plate; the first spring washer 252 provides elasticity to prevent the nut from loosening; the first nut 251 mates with the threaded connection at the upper end of the central shaft to achieve a tight fit.

[0055] The second nut assembly 26 is used to fix the lower end of the central shaft. Its structure, from bottom to top, consists of a second nut 261, a second spring washer 262, and a second flat washer 263. The function of each component is similar to that of the first nut assembly. The second nut 261 mates with the threaded connection at the lower end of the central shaft and works together with the first nut assembly to achieve axial fastening of the central shaft.

[0056] In a preferred embodiment of this example, the first nut is an M12 locking nut, the second nut is an M6 locking nut, the first spring washer is a Φ12 spring washer, the second spring washer is a Φ6 spring washer, the first flat washer is a Φ12 flat washer, and the second flat washer is a Φ6 special enlarged flat washer.

[0057] Implementation, for example Figure 1 As shown, preferably, the double bearing 23 is a deep groove ball bearing.

[0058] The model should be selected based on the load-bearing capacity and rotational accuracy requirements of the turntable. Dual bearings must be used in pairs to improve the stability and load-bearing capacity of the rotating components.

[0059] Deep groove ball bearings are the most widely used type of rolling bearing. They are simple in structure, easy to use, and suitable for high-speed, low-noise applications. Using deep groove ball bearings as bearings in rotating components can meet the requirements for smooth rotation, load-bearing capacity, and service life of packing table turntables, while also being relatively low in cost, offering high cost-effectiveness.

[0060] Optionally, other types of bearings, such as tapered roller bearings and angular contact ball bearings, can be selected according to actual needs in this invention.

[0061] The dual bearings utilize the advantages of deep groove ball bearings. Their inner and outer ring groove design can simultaneously withstand radial and axial loads, making them suitable for scenarios with frequent turntable rotation. They offer advantages such as high load capacity, low friction, and long service life.

[0062] Preferably, the turntable 21 has a disc-shaped structure, and its surface is provided with grooves for placing the resistor box.

[0063] The turntable can be designed as a disc-shaped structure for easy 360-degree rotation. To better secure the resistor boxes and prevent them from slipping during rotation, the surface of the turntable can be provided with grooves for placing the resistor boxes. The shape and size of the grooves can be customized according to the specifications of resistor boxes that are commonly packaged.

[0064] In one optional embodiment of this invention, the turntable surface is machined with circular or rectangular grooves, the depth of which matches the base of the resistor box. These grooves provide initial positioning, preventing the resistor box from shifting during rotation and improving packaging efficiency.

[0065] Preferably, both the upper wooden board 13 and the lower wooden board 14 are circular board structures.

[0066] To harmonize with the disc-shaped turntable structure and considering both overall aesthetics and ease of manufacturing, both the upper wooden board 13 and the lower wooden board 14 are circular. Circular wooden boards are not only easier to manufacture but also visually more harmonious and unified with the circular turntable and bearing seats. Depending on actual design requirements, the upper and lower wooden boards can also be other shapes, such as rectangular or square.

[0067] Preferably, both the upper support plate 11 and the lower support plate 12 are rectangular plate structures and are made of metal.

[0068] To ensure the strength and rigidity of the support components, both the upper support plate 11 and the lower support plate 12 can be rectangular plate structures, preferably made of metal materials such as steel plates or aluminum alloy plates. Rectangular plate structures are easy to process and connect, while metal materials provide sufficient strength and load-bearing capacity to ensure that the support components can stably support the weight of the entire packing platform and resistor box. Using metal materials also improves the durability and service life of the support components.

[0069] Specifically, the upper and lower support plates are made of Q235 carbon steel.

[0070] Preferably, the adjusting groove 32 is an elongated through hole.

[0071] Optionally, the sliding connection of the limit bar, such as a slider with bolts, can be continuously adjusted in position within the through hole to adapt to the fixing requirements of resistor boxes of different sizes.

[0072] In summary, the resistor box packing platform disclosed in this utility model combines a support component, a rotating component, and an adjustable limiting component to form a compact and fully functional packing operation platform. Through the synergistic effect of the fixed base, the stable rotating mechanism, and the adjustable limiting device, the operational efficiency and convenience of resistor box packing are improved. Its reasonable structural design and carefully selected materials balance practicality and economy, effectively meeting the packing needs of resistor box manufacturers and possessing significant potential for widespread application.

[0073] The working principle of the resistor box packaging platform described in this utility model is as follows: When packaging resistor boxes, the resistor box is first placed on the working surface of the turntable. The operator can adjust the position of the limit clips using the limit adjustment component according to the size of the resistor box, ensuring the limit clips effectively fix the resistor box and prevent it from sliding during packaging. Subsequently, the operator can manually rotate the turntable, causing the resistor box to rotate 360 ​​degrees. Because the turntable uses a double-bearing and central shaft rotation structure, the rotation process is smooth and stable. As the turntable rotates, the operator can easily access all sides of the resistor box to perform packaging operations such as wrapping and sealing, without frequently moving themselves or the resistor box, thus improving packaging efficiency. The support component, as the base of the entire packaging platform, provides stable support, ensuring the safety and stability of the packaging process.

[0074] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
