Description

Technical Field

[0001] This utility model relates to the field of packaging material processing technology, and in particular to a material feeding mechanism. Background Technology

[0002] Packaging materials play a crucial protective role in product transportation, storage, and sales. Common packaging materials include EPE (expanded polyethylene), cardboard, polyethylene (PE), and polyvinyl chloride (PVC). Among these, EPE, as a new type of environmentally friendly packaging material, is widely used in many packaging applications due to its excellent comprehensive performance. Specifically, EPE possesses excellent physical cushioning properties, effectively preventing shock and impact, and exhibits good resilience and toughness. Furthermore, it also possesses water-proof, moisture-proof, sound-insulating, and heat-insulating properties, and can be repeatedly recycled, aligning with current green and environmentally friendly concepts. Simultaneously, EPE's strong plasticity makes it suitable for packaging various irregularly shaped products, and its excellent chemical resistance makes it outstanding in packaging various industrial products, electronic products, and fragile items, making it one of the ideal packaging materials.

[0003] Despite the superior performance of packaging materials themselves, in practical applications, especially in industrialized mass production scenarios, a series of subsequent processing techniques are still required to achieve efficient and stable packaging structures. Taking lamination as an example, the manufacturing process typically involves bonding two or more pieces of packaging material together to improve the overall protective capabilities and adaptability of the packaging. However, many packaging materials are inherently non-moldeable or have irregular structures, making the lamination process complex and necessitating the use of specialized lamination equipment.

[0004] Currently used lamination equipment typically involves a spraying system uniformly applying adhesive to the surface of one package, followed by a gripping mechanism precisely gripping another package and laminating it to the adhesive-coated package. The entire lamination process requires a continuous supply of packages from a feeding mechanism to ensure production continuity and efficiency. For ease of feeding, packages are usually neatly stacked on the feeding mechanism, and molds are often used on the feeding platform to position the packages and prevent slippage or misalignment. However, existing feeding molds are mostly custom-designed, with their shape and size requiring strict matching to the package being processed.

[0005] Because packaging components come in a variety of sizes and specifications in actual production, each type of packaging component almost always requires a separate mold for its feeding mechanism. This low adaptability of the mold design not only leads to frequent mold changes and cumbersome operations, but also significantly increases the manufacturing and management costs of the molds, thereby raising the overall production cost. Utility Model Content

[0006] The technical problem this utility model aims to solve is: the need to design a separate mold for the feeding mechanism for almost every type of packaging.

[0007] To solve the above-mentioned technical problems, this utility model provides a feeding mechanism, comprising: a feeding rack with a first slide rail; a sliding rack slidably disposed on the first slide rail, the sliding rack having a second slide rail and a third slide rail, the length direction of the second slide rail being perpendicular to the length direction of the third slide rail; a shelf disposed on the sliding rack, the shelf having a feeding position, the shelf being located above the second and third slide rails; two first clamping plates slidably disposed on the second slide rail, the two first clamping plates being located on both sides of the feeding position; and two second clamping plates slidably disposed on the third slide rail, the two second clamping plates being located on the other two sides of the feeding position.

[0008] Furthermore, it also includes a first adjusting rod and a second adjusting rod, both of which are rotatably mounted on the sliding frame. The first adjusting rod passes through the bottom of the first clamping plate. When the first adjusting rod rotates, the first clamping plate moves away from or closer to the feeding position. The second adjusting rod passes through the bottom of the second clamping plate. When the second adjusting rod rotates, the second clamping plate moves away from or closer to the feeding position.

[0009] Furthermore, it also includes a third adjusting rod, which is provided with a first bevel gear, and a second adjusting rod is provided with a second bevel gear that meshes with the first bevel gear, and the third adjusting rod is parallel to the first adjusting rod.

[0010] Furthermore, both the first adjusting rod and the third adjusting rod have a rotating disk at one end.

[0011] Furthermore, the angle between the bottom edge of the first clamping plate and the second slide rail is in the range of 80°-88°, and the angle between the bottom edge of the second clamping plate and the third slide rail is in the range of 80°-88°.

[0012] Furthermore, the first clamping plate is provided with a first protrusion extending in a vertical direction, and the first protrusions of the two first clamping plates are arranged facing each other. The second clamping plate is provided with a second protrusion extending in a vertical direction, and the second protrusions of the two second clamping plates are arranged facing each other.

[0013] Furthermore, the sliding frame is provided with two racks, which are located on both sides of the sliding frame respectively. The first clamping plate and the second clamping plate are located between the two racks, and the shelf is engaged with the tooth grooves of the racks.

[0014] Furthermore, the shelf comprises multiple support rods, which are engaged in the toothed grooves of the rack. The second clamping plate has through holes, and at least one of the support rods passes through the through holes and is engaged in the toothed grooves of the rack.

[0015] Furthermore, the sliding frame is provided with a plurality of shelves, which are evenly arranged along the length of the first slide rail.

[0016] Furthermore, the sliding frame is also provided with a sliding groove that is adapted to the first slide rail, and the sliding frame can slide along the first slide rail.

[0017] Compared with the prior art, the feeding mechanism provided by this utility model has the following advantages: by setting a second and a third slide rail that are perpendicular to each other on the sliding frame, and arranging a first and a second slidable clamping plate on the slide rail respectively, the four clamping plates can be freely adjusted in two orthogonal directions. This allows the distance between the clamping plates to be flexibly adjusted according to the actual size of the package at the feeding position, thereby achieving reliable clamping of packaged items of different specifications and shapes.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope. It should be noted that, unless otherwise specifically stated, the relative arrangement and numerical values ​​of the components and steps described in these examples do not limit the scope of this utility model.

[0025] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0027] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0029] like Figures 1 to 4 As shown in the figure, this utility model embodiment discloses a feeding mechanism, including: a feeding rack 1, on which a first slide rail 11 is provided; a sliding rack 2, which is slidably disposed on the first slide rail 11, and the sliding rack 2 is provided with a second slide rail 21 and a third slide rail 22, the length direction of the second slide rail 21 being perpendicular to the length direction of the third slide rail 22; a shelf 3, which is disposed on the sliding rack 2, and the shelf 3 is provided with a feeding position 301, the shelf 3 being located above the second slide rail 21 and the third slide rail 22; two first clamping plates 4, which are slidably disposed on the second slide rail 21, and the two first clamping plates 4 are respectively located on both sides of the feeding position 301; and two second clamping plates 5, which are slidably disposed on the third slide rail 22, and the two second clamping plates 5 are respectively located on the other two sides of the feeding position 301.

[0030] The feeding mechanism of this application places the package 9 on the feeding position 301 of the shelf 3, and uses the second slide rail 21 and the third slide rail 22 to slide the first clamping plate 4 and the second clamping plate 5 around the package 9, thereby clamping the package 9 of different specifications. The sliding frame 2 moves the package 9 to the gripping mechanism of the bonding equipment through the first slide rail 11.

[0031] By setting mutually perpendicular second slide rails 21 and third slide rails 22 on the sliding frame 2, and arranging slidable first clamping plates 4 and second clamping plates 5 on the slide rails respectively, the four clamping plates can be freely adjusted in two orthogonal directions. This structure can flexibly adjust the distance between the clamping plates according to the actual size of the package 9, thereby achieving reliable clamping of packages 9 of different specifications and shapes. No mold replacement is required; adaptation can be achieved simply by sliding adjustment, greatly improving versatility and compatibility.

[0032] Compared to traditional feeding mechanisms that require the manufacture and replacement of dedicated molds for each type of packaging component 9, this invention utilizes a combination of slide rails and adjustable clamping plates to achieve rapid adaptation to packaging components 9 of different sizes. This effectively avoids the material consumption and manual operation caused by frequent mold changes, significantly reducing mold manufacturing and maintenance costs and helping manufacturers achieve low-cost flexible manufacturing. Adjusting the clamping plates is sufficient to position and clamp different packaging components 9 without requiring machine downtime for mold changes or rearrangement of the feeding structure, shortening production preparation time and improving the continuous operation capability of the production line. Furthermore, the mechanism's simple structure makes it easy to integrate into automated lamination equipment, enhancing overall automation, reducing manual intervention, and improving feeding accuracy and efficiency.

[0033] By clamping the package 9 from four directions using four clamping plates, it effectively prevents the package 9 from shaking, shifting, or tipping during the feeding process, improving the accuracy and stability of the package 9's positioning. This ensures precise gripping by the subsequent laminating equipment, avoids laminating failures or defects due to positional deviations, and improves product yield. Current manufacturing trends towards flexible production methods involving small batches, multiple varieties, and customization. The feeding mechanism of this invention can quickly respond to changes in product models; simply adjusting the clamping plates is sufficient to adapt to the size and specifications of new products, meeting the needs of flexible manufacturing and enhancing the company's market responsiveness.

[0034] Specifically, the sliding arrangement of the first clamping plate 4 and the second clamping plate 5 includes, but is not limited to, ball screws, threaded drives and trapezoidal screws.

[0035] like Figure 1 and Figure 2 As shown, in an optional embodiment of the utility model, it further includes a first adjusting rod 6 and a second adjusting rod 7. Both the first adjusting rod 6 and the second adjusting rod 7 are rotatably mounted on the sliding frame 2. The first adjusting rod 6 passes through the bottom of the first clamping plate 4. When the first adjusting rod 6 rotates, the two first clamping plates 4 move away from or closer to the feeding position 301. The second adjusting rod 7 passes through the bottom of the second clamping plate 5. When the second adjusting rod 7 rotates, the two second clamping plates 5 move away from or closer to the feeding position 301.

[0036] By setting a first adjusting rod 6 and a second adjusting rod 7 on the sliding frame 2, the moving positions of the first clamping plate 4 and the second clamping plate 5 are controlled respectively. The user only needs to rotate the adjusting rod to achieve synchronous sliding adjustment of the clamping plates. Compared with the traditional manual sliding or disassembly adjustment method, the operation process is greatly simplified and the adjustment efficiency and operation convenience are improved.

[0037] Specifically, the adjusting rod achieves smooth advancement or retraction of the clamping plate through a transmission mechanism such as a thread or cam, resulting in higher control precision. During adjustment, the clamping plate moves smoothly, minimizing wobbling or displacement errors, which helps to firmly hold the package 9 in the appropriate position, thus ensuring accurate material feeding and positioning, and providing a good foundation for subsequent bonding operations.

[0038] Specifically, the left and right sections of the first adjusting rod 6 and the second adjusting rod 7 are provided with threads in different directions. The package 9 at the feeding position 301 is located between the threads of the left and right sections. When the adjusting rod rotates, the clamps on the left and right sections of the adjusting rod will move towards or away from each other, thereby achieving reliable clamping of package 9 of different specifications and shapes.

[0039] Specifically, the first adjusting rod 6 and the second adjusting rod 7 can be manually rotated or driven by a motor, thereby causing the first clamping plate 4 and the second clamping plate 5 to clamp the material at the feeding position 301. In use, the operator or control system places the package 9 in the feeding position 301 of the shelf 3, and slides the first clamping plate 4 and the second clamping plate 5 to a suitable position using a motor or manually, fitting them to the edges of the package 9 to achieve stable clamping. Then, the sliding frame 2 can move on the first slide rail 11, conveying the package 9 to the gripping mechanism of the bonding equipment, completing the feeding process.

[0040] like Figure 2 and Figure 3 As shown, in an optional embodiment of the utility model, a third adjusting rod 8 is further included. The third adjusting rod 8 is provided with a first bevel gear 81, and the second adjusting rod 7 is provided with a second bevel gear 71 that meshes with the first bevel gear 81. The third adjusting rod 8 is parallel to the first adjusting rod 6.

[0041] By setting a meshing first bevel gear 81 and a second bevel gear 71 between the third adjusting rod 8 and the second adjusting rod 7, mechanical linkage between the two adjusting rods is achieved. The user only needs to operate the third adjusting rod 8 to simultaneously drive the second adjusting rod 7 to rotate, thereby adjusting the second clamping plate 5. This avoids multi-point, dispersed operation and improves overall adjustment efficiency. The parallel arrangement of the third adjusting rod 8 and the first adjusting rod 6 allows the adjustment operation control to be concentrated on one side or one side, facilitating unified operation by the operator, improving ergonomics, and reducing spatial interference caused by the dispersed arrangement of the adjusting rods, thus optimizing the compactness and rationality of the equipment structure.

[0042] like Figure 1 and Figure 2 As shown, in an optional embodiment of the utility model, one end of both the first adjusting rod 6 and the third adjusting rod 8 is provided with a rotating disk 61.

[0043] Compared to traditional thin rods or small knobs, the rotating disc 61 has a larger force-bearing area and a wider operating interface. Users can more easily perform rotation operations with their palms or fingers, effectively reducing the operating force during adjustment and improving user comfort. This advantage is particularly evident in work environments requiring frequent adjustments or long-term operation. Due to the larger diameter of the rotating disc 61, the angle changes during rotation are more subtle, allowing operators to more precisely control the movement distance of the clamping plate. This enables higher-precision clamping and positioning of the packaged item 9, further improving the adjustment accuracy and reliability of the feeding mechanism.

[0044] like Figure 2 As shown, in an optional embodiment of the utility model, the angle α formed by the bottom edge of the first clamping plate 4 and the second slide rail 21 is in the range of 80°-88°, and the angle b formed by the bottom edge of the second clamping plate 5 and the third slide rail 22 is in the range of 80°-88°.

[0045] When the angle between the bottom edge of the clamping plate and the slide rail is less than 90°, the clamping plate will be slightly tilted, forming a "closed" surrounding clamping effect, effectively enhancing the restriction on the packaging 9 around its perimeter. This structure can significantly improve clamping stability, preventing the packaging 9 from sliding or dislodging in the vertical direction due to gravity or transportation vibration, ensuring a smooth feeding process. Since the clamping plate's tilt angle is slightly less than the vertical state, the packaging 9 will be slightly pressed towards the center of the feeding position 301 of the shelf 3 when clamped, thereby achieving initial centering and orientation, which helps improve the positioning accuracy of the packaging 9 on the feeding position 301, providing a more accurate picking reference for the subsequent laminating equipment and reducing laminating errors. A structure with an angle between 80° and 88° can adapt to more packaging 9 with different shapes or inclined edges and irregularities, especially for packaging structures with chamfered, rounded, or gently sloping edges, providing a contact surface that better matches its geometric contour and improving overall compatibility.

[0046] By using an angle between the bottom edge of the clamping plate and the slide rail ranging from 80° to 88°, the package 9 is transported to the gluing assembly in a slightly horizontal tilted state. Positioning the package 9 at a tilt of 2-10 degrees can reduce the temperature of the gluing assembly and the area of ​​damage caused by compression.

[0047] like Figure 1 and Figure 2As shown, in an optional embodiment of the utility model, the first clamping plate 4 is provided with a first protrusion 41 extending in the vertical direction, and the first protrusions 41 of the two first clamping plates 4 are arranged facing each other. The second clamping plate 5 is provided with a second protrusion 51 extending in the vertical direction, and the second protrusions 51 of the two second clamping plates 5 are arranged facing each other.

[0048] By vertically positioning the first protrusion 41 and the second protrusion 51 on the inner side of the clamping plate, a localized raised structure is formed on the contact surface with the package 9. Compared to a flat clamping surface, this significantly increases the contact friction during clamping, effectively preventing the package 9 from sliding or shaking during clamping and ensuring stable material supply. The first protrusions 41 of the two first clamping plates 4 face each other, and the second protrusions 51 of the two second clamping plates 5 also face each other, forming a four-sided closed limiting structure. This structure provides physical barriers in both the lateral and longitudinal directions after the package 9 is placed, contributing to a more stable clamping effect. It is suitable for package 9 of different sizes and materials. The protrusions can disperse pressure during clamping, preventing the package 9 from being directly squeezed by the large area of ​​the clamping plate, thus avoiding deformation or damage. This is particularly suitable for lightweight cushioning packaging materials such as pearl cotton and foam board, which are prone to indentation and deformation. The raised design not only facilitates the clamping of standard-shaped packaging 9, but also better adapts to packaging 9 with grooves, curved surfaces or irregular structures on the edges, improving the applicability of the feeding mechanism to various irregular-shaped parts and enhancing versatility and flexible production capabilities.

[0049] like Figure 1 and Figure 2 As shown, in an optional embodiment of the utility model, the sliding frame 2 is provided with two racks 23, which are located on both sides of the sliding frame 2 respectively. The first clamping plate 4 and the second clamping plate 5 are located between the two racks 23, and the shelf 3 is snapped into the tooth groove of the rack 23.

[0050] The snap-fit ​​connection between the rack 23 and the shelf 3 ensures a stable and secure installation, effectively preventing displacement, loosening, or misalignment of the shelf 3 due to vibration, repeated clamping, or sliding, thus improving the overall structural reliability of the feeding mechanism. The multiple slots on the rack 23 allow for quick adjustment of the shelf 3's position. Operators simply snap the shelf 3 into different slots to flexibly change the height or relative position of the feeding position 301, adapting to packaging materials 9 of different thicknesses or stacking structures, thus enhancing the equipment's adaptability and versatility. The shelf 3 is snap-fitted onto the rack 23, requiring no additional screws or welding, simplifying operation and facilitating later maintenance, quick replacement, or cleaning. Furthermore, when the shelf 3 needs to be replaced to accommodate different types of packaging materials 9, disassembly and assembly can be completed quickly, improving maintenance efficiency and the equipment's sustainable use.

[0051] like Figure 2 and Figure 4 As shown, in an optional embodiment of the utility model, the shelf 3 consists of multiple support rods 31, which are snapped into the tooth grooves of the rack 23. The second clamping plate 5 is provided with a through hole 501, and at least one support rod 31 passes through the through hole 501 and is snapped into the tooth grooves of the rack 23.

[0052] By configuring the shelf 3 with multiple support rods 31, the feeding mechanism can adapt to the needs of packages 9 of different sizes and specifications. Users can freely increase or decrease the number and position of the support rods 31 according to actual needs, thereby flexibly adjusting the load-bearing capacity of the feeding shelf 1 and enhancing the versatility and flexibility of the equipment. The support rods 31 not only share the weight of the packages 9, but are also stably fixed in the tooth grooves of the rack 23 through a snap-fit ​​method, enhancing the load-bearing capacity of the entire shelf 3. After the support rods 31 pass through the through holes 501 of the second clamping plate 5, the stability of the structure is further improved, avoiding deformation or displacement caused by concentrated force. The snap-fit ​​and through-hole 501 structure of the support rods 31 makes the installation, adjustment, and replacement of the entire shelf 3 easier and reduces the difficulty of manual operation. Users can quickly disassemble or reconfigure the support rods 31 to adapt to the needs of different types of packages 9, reducing equipment maintenance time and costs and improving production efficiency. As an independent module, the support rods 31 are easy to expand or replace during future equipment upgrades. With the development of technology or changes in production requirements, the number of support rods 31 can be easily increased or adjusted, and even combined with automated adjustment equipment to achieve more intelligent operation, providing a good foundation for future automation upgrades.

[0053] like Figure 1 and Figure 3 As shown, in an optional embodiment of the utility model, the sliding frame 2 is provided with multiple shelves 3, which are evenly arranged along the length direction of the first slide rail 11. By evenly arranging the multiple shelves 3 along the length direction of the first slide rail 11, multiple packages 9 can be accommodated simultaneously, and the movement of the sliding frame 2 can sequentially move the packages 9 to the gripping position. This can effectively improve the feeding efficiency, reduce the waiting time of the packages 9, optimize the production process, and is suitable for efficient automated production lines. The arrangement of multiple shelves 3 allows more packages 9 to be accommodated at the same time, significantly improving the space utilization rate. It can realize the storage and transportation of more packages 9 in a limited space, adapt to the production needs of high density and high load, and improve the overall production capacity. Since the multiple shelves 3 are evenly arranged along the slide rail, the load and movement speed between each shelf 3 and the slide rail are consistent. This helps to reduce the vibration or jamming caused by uneven load during the operation of the equipment, ensure the stability and consistency of the feeding mechanism, and avoid system failures or efficiency reduction caused by uneven feeding.

[0054] In an optional embodiment of the utility model, the sliding frame 2 is further provided with a sliding groove adapted to the first slide rail 11, and the sliding frame 2 can slide along the first slide rail 11.

[0055] By adapting the chute to the first slide rail 11, the sliding frame 2 remains stable during sliding, avoiding jamming or offset caused by misalignment or excessive gaps. The chute effectively guides the sliding frame 2 to slide smoothly along the predetermined track, thereby improving the accuracy and operational stability of the feeding mechanism. The precise fit between the chute and the slide rail reduces friction between the sliding frame 2 and the track, thus reducing wear on the sliding components. Compared to traditional sliding methods, the chute structure effectively reduces component wear, extends equipment lifespan, and lowers daily maintenance frequency and costs.

[0056] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
