Description

Technical Field

[0001] This utility model relates to the field of automated machinery, and in particular to a material transfer device for processing composite aluminum alloy doors and windows. Background Technology

[0002] Material handling is a crucial step in the production of aluminum alloy doors and windows, involving a series of operations from receiving, processing, and assembling raw materials to transporting the final products.

[0003] Currently, widely used material handling devices, when there is a vertical height difference between them and the next device, require operators to frequently manually move or lift heavy objects. This not only greatly increases the physical exertion of operators but also seriously affects work efficiency. Prolonged heavy physical labor can easily lead to operator fatigue and even occupational injuries such as muscle strains and sprains. Furthermore, manually moving heavy objects increases safety risks during operation; improper operation or mistakes can easily cause material damage or personal injury, posing a serious threat to production safety. In addition, current material handling devices typically extend horizontally for transport. This transport structure, which cannot fully utilize vertical space, is ill-suited to the diverse and abundant materials and high storage space requirements in the production of aluminum alloy doors and windows. Moreover, this transport structure cannot effectively utilize the vertical space of the factory, resulting in a large occupation of floor space and extremely low space utilization. This problem is particularly pronounced in factories with limited space; the lack of lifting capabilities in the transfer devices further exacerbates the space shortage, severely restricting the expansion of production scale and the improvement of production efficiency.

[0004] Therefore, it is necessary to provide a material transfer device for composite aluminum alloy door and window processing that can effectively improve transfer efficiency and space utilization. Utility Model Content

[0052] Please refer to Figure 1 - Figure 4 One embodiment of this application provides a material transfer device 100 for processing composite aluminum alloy doors and windows, used for transferring a material box 200 containing materials. The transfer device 100 includes: a base frame 10, a first conveying part 20, a lifting part 30, and a second conveying part 40.

[0053] The first conveying unit 20 is fixedly connected to the base frame 10 and extends along a first direction F1. The lifting unit 30 is fixedly connected to the base frame 10 and includes a carrying plate 31 extending along a second direction F2, a support plate 32 fixedly connected to the carrying plate 31, and a pneumatic unit 33 abutting against the support plate 32 on the side opposite to the carrying plate 31. The second conveying unit 40 is fixedly connected to the base frame 10 and also extends along the second direction F2. The projection of the first conveying unit 20 in the vertical direction partially overlaps with the projection of the second conveying unit 40 in the vertical direction. When viewed along a direction parallel to the support plate 32, the lifting unit 30 is located between the first conveying unit 20 and the second conveying unit 40. The material box 200 is transported to the lifting unit 30 along the first direction F1 via the first conveying unit 20. After the pneumatic unit 33 descends the lifting unit 30 in the vertical direction, the material box 200 is transported to the second conveying unit 40 along the second direction F2.

[0054] The vertical projections of the first conveyor section 20 and the second conveyor section 40 overlap, effectively saving space and making the entire transfer device 100 more compact. Simultaneously, the lifting section 30 is located between the first conveyor section 20 and the second conveyor section 40, forming a highly efficient transfer channel. The material box 200 can first be transported from the first conveyor section 20 along the first direction F1 to the lifting section 30, then descend vertically via the pneumatic section 33, and finally be transported along the second direction F2 on the second conveyor section 40. This continuous transfer process greatly improves transfer efficiency. The lifting section 30 allows the material box 200 to be transferred between different heights, increasing the flexibility of the transfer device 100. This is very useful for processing equipment or storage areas at different heights. Through the different extension directions of the first conveyor section 20 and the second conveyor section 40, the material box 200 can achieve directional changes during transfer. This design allows the transfer device 100 to adapt to more complex transfer needs. The pneumatic section 33, as the power source of the lifting section 30, features precise control and rapid response. The pneumatic unit 33 ensures the smooth and safe lifting of the material box 200. The fixed connection between the base frame 10, the first conveyor 20, the lifting unit 30, and the second conveyor 40 ensures the structural strength of the entire transfer device 100. This robust structural design enables the transfer device 100 to withstand the weight of large materials and various impacts during the transfer process.

[0055] More preferably, the transfer device 100 further includes a crossbeam 50. The crossbeam 50 is fixedly connected to the base frame 10. When viewed in a direction perpendicular to the support plate 32, the four crossbeams 50 are parallel to each other, and when viewed in a direction parallel to the support plate 32, the projections of the four crossbeams 50 in the horizontal direction do not overlap.

[0056] The crossbeams 50, as an important component of the transfer device 100, primarily provide structural support and stability. By fixing the crossbeams 50 to the base frame 10, a more robust frame is formed, enhancing the load-bearing capacity and deformation resistance of the entire transfer device 100. This is crucial for ensuring the safety and stability of materials during transfer. From a spatial layout perspective, the four crossbeams 50 are parallel to each other, and their horizontal projections do not overlap, which helps optimize space utilization. The parallel and non-overlapping crossbeam layout reduces the horizontal space occupied by the transfer device 100, making the entire device more compact and efficient. Simultaneously, this layout also helps reduce material interference and collisions during transfer, improving transfer efficiency. Furthermore, the crossbeams 50 provide a foundation for the installation and fixing of other components (such as the first conveying section 20, the lifting section 30, and the second conveying section 40). By precisely installing these components on the crossbeams 50, the accuracy of their relative positions and angles can be ensured, further improving the precision and reliability of the transfer device 100.

[0057] More preferably, the first conveying unit 20 includes: a first guard 21 and a first pulley block 22.

[0058] The first guard edge 21 is fixedly connected to the crossbeam 50 and is located on the side of the crossbeam 50 opposite to the second conveying section 40. The first pulley block 22 is fixedly connected to the first guard edge 21 and is located on the side of the first guard edge 21 opposite to the crossbeam 50. The two first guard edges 21 and the two first pulley blocks 22 extend along the first direction F1, and the material box 200 moves towards the lifting section 30 along the two first pulley blocks 22.

[0059] The first guard edge 21 is fixedly connected to the crossbeam 50 and located on the side of the crossbeam 50 opposite to the second conveyor section 40. This design provides excellent material guidance. When the material box 200 moves along the first direction F1, the first guard edge 21 ensures that the material box 200 does not deviate from the predetermined transfer path, improving the accuracy of the transfer. Simultaneously, the first guard edge 21 provides additional support for the material box 200, enhancing the stability of the material during transfer. This helps reduce material swaying and tilting during transfer, ensuring safe transport. The first pulley block 22 is fixedly connected to the first guard edge 21 and located on the side of the first guard edge 21 opposite to the crossbeam 50. The pulley block design allows the material box 200 to roll along the pulleys, thereby reducing the frictional resistance between the material and the conveyor section and improving transfer efficiency. The rolling motion of the pulley block not only reduces energy consumption but also extends the service life of the conveyor section. Furthermore, the arrangement of the pulley block ensures the smoothness and continuity of the material box 200 during transfer. In addition, the combination of the first guard 21 and the pulley block makes the loading and unloading operation of the material box 200 more convenient and efficient.

[0060] More preferably, the second conveying unit 40 includes: a second guard 41 and a second pulley assembly 42.

[0061] The second guard edge 41 is fixedly connected to the crossbeam 50 and is located on the side of the crossbeam 50 opposite to the second conveying section 40. The second pulley block 42 is fixedly connected to the second guard edge 41 and is located on the side of the second guard edge 41 opposite to the crossbeam 50. The two second guard edges 41 and the two second pulley blocks 42 extend along the second direction F2, and the material box 200 moves towards the lifting section 30 along the two second pulley blocks 42.

[0062] In the material transfer device 100 for composite aluminum alloy door and window processing, the second conveying section 40 adopts a combination design of the second guard 41 and the second pulley block 42, following specific layout principles, mainly for the following considerations: First, the second guard 41 is fixedly connected to the side of the crossbeam 50 opposite to the first conveying section 20. This layout ensures that the material box 200 can be effectively guided and supported when moving along the second direction F2, preventing the material box 200 from deviating from the predetermined path or tipping over, thereby improving the safety and stability of the transfer. Second, the second pulley block 42 is fixedly connected to the second guard 41 and located on the side opposite to the crossbeam 50. This design allows the material box 200 to roll smoothly along the pulleys, significantly reducing the frictional resistance between the material and the conveying section, which not only improves the transfer efficiency but also helps to reduce energy consumption and extend the service life of the conveying section. Meanwhile, the two second guard edges 41 and the two second pulley blocks 42 extend along the second direction F2, respectively. This layout makes the second conveying section 40 more compact and efficient in structure, optimizes space utilization, and ensures the stability and continuity of the material box 200 during the transfer process. Furthermore, the combined design of the second guard edges 41 and the pulley blocks facilitates daily maintenance and cleaning, reducing maintenance costs and time. Therefore, this design comprehensively considers multiple aspects such as material guidance, sliding efficiency, space utilization, and ease of maintenance, contributing to improving the performance and reliability of the entire transfer device 100.

[0063] More preferably, the second conveying section 40 further includes a buffer pad 43. The buffer pad 43 is fixedly connected to one end of the two guard edges, and this end is located on the side of the second guard edge 41 that is opposite to the lifting section 30. After the material box 200 is transported to the second conveying section 40 along the second direction F2, it abuts against the buffer pad 43.

[0064] In the material transfer device 100 for composite aluminum alloy door and window processing, the addition of a buffer pad 43 to the second conveying section 40 is primarily for improving material transfer safety and protecting the material box 200 and the conveying section structure. Specifically, the buffer pad 43 is fixedly connected to the end of the second guard 41 furthest from the lifting section 30. When the material box 200 is transported along the second direction F2 to the second conveying section 40 and arrives at this end, it will first come into contact with the buffer pad 43. This design effectively reduces the impact force that the material box 200 may generate due to inertia or improper operation, preventing the material box 200 from directly impacting the second guard 41 or other components of the conveying section, thereby avoiding damage to the material box 200 and wear and deformation of the conveying section structure.

[0065] More preferably, the lifting unit 30 further includes a base plate 34. The base plate 34 is fixedly connected to the base frame 10 and is located on the side of the support plate 32 opposite to the carrying plate 31.

[0066] The base plate 34 serves as a stable foundation for the lifting unit 30, enhancing its overall structural strength. By fixing the base plate 34 to the base frame 10, the stability and reliability of the lifting unit 30 during vertical movement are ensured, preventing offset or swaying due to load or vibration, thus guaranteeing the safety and accuracy of material transfer. The base plate 34 is located on the side of the support plate 32 opposite to the carrying plate 31, optimizing space utilization. This allows for a compact arrangement of the various components of the lifting unit 30, reducing unnecessary space waste and improving the overall compactness and efficiency of the transfer device 100. The base plate 34 also provides a foundation for mounting and fixing other components of the lifting unit 30 (such as the drive mechanism and guide mechanism). By precisely mounting these components on the base plate 34, the accuracy of their relative positions and angles is ensured, further improving the precision and reliability of the lifting unit 30.

[0067] More preferably, the lifting unit 30 further includes guide shafts 35. Four guide shafts 35 are located between the support plate 32 and the base plate 34. One end of each guide shaft 35 is fixedly connected to the support plate 32, and the other end passes through the base plate 34 and is slidably connected to it. The four guide shafts 35 are parallel to each other to guide the support plate 32 to descend or rise vertically.

[0068] The guide shafts 35 serve as crucial guiding elements during the lifting and lowering of the support plate 32, ensuring its smooth vertical movement. One end of each guide shaft 35 is fixedly connected to the support plate 32, while the other end passes through the base plate 34 and slides along it. This arrangement allows the support plate 32 to move precisely along the guide shafts 35 during lifting, preventing offset or swaying and ensuring the accuracy and stability of material transfer. The parallel arrangement of the four guide shafts 35 further enhances the structural rigidity and stability of the lifting unit 30. This design not only helps distribute the load on the support plate 32 but also effectively resists external interference and vibration, improving the overall durability and reliability of the lifting unit 30. The sliding connection between the guide shafts 35 and the base plate 34 allows the lifting unit 30 to maintain low frictional resistance during lifting, thereby improving transfer efficiency and reducing energy consumption. Simultaneously, the sliding connection facilitates daily maintenance and cleaning, reducing maintenance costs.

[0069] More preferably, the pneumatic unit 33 further includes a cylinder 33A and a push rod 33B.

[0070] The cylinder 33A is fixedly connected to the base plate 34 and is located on the side of the base plate 34 opposite to the support plate 32. One end of the push rod 33B is slidably connected to the cylinder 33A, and the other end abuts against the support plate 32. The push rod 33B passes through the base plate 34 and pushes the support plate 32 to move in the vertical direction.

[0071] In this design, cylinder 33A serves as the power source for the pneumatic unit 33. It is fixedly connected to the base plate 34 on the side facing away from the support plate 32. This arrangement allows cylinder 33A to stably provide thrust, driving the push rod 33B to move vertically. The position of cylinder 33A ensures that it is not disturbed by the lifting and lowering movement of the support plate 32 during operation, thus guaranteeing the stability and reliability of the pneumatic unit 33. The design of the push rod 33B allows it to directly abut against the support plate 32 and transmit the thrust generated by cylinder 33A to the support plate 32 through the base plate 34, pushing it to rise or fall vertically. This direct transmission method reduces energy loss and improves transfer efficiency. Simultaneously, the sliding connection design between the push rod 33B and cylinder 33A allows the push rod 33B to smoothly extend and retract within cylinder 33A, further ensuring the smoothness and accuracy of the lifting and lowering movements. The combined design of cylinder 33A and push rod 33B also facilitates daily maintenance and inspection. Since the cylinder 33A is fixedly connected to the base plate 34, and the push rod 33B passes through the base plate 34 and abuts against the support plate 32, this layout allows maintenance personnel to easily access the cylinder 33A and the push rod 33B for inspection and maintenance, reducing maintenance difficulty and cost.

[0072] More preferably, the lifting part 30 further includes a rotary connector 36 and a compression spring 37.

[0073] The rotary connector 36 is fixedly connected between the support plate 32 and the carrying plate 31. One end of the compression spring 37 is fixedly connected to the support plate 32, and the other end is fixedly connected to the carrying plate 31. The compression spring 37 is located between the support plate 32 and the carrying plate 31, and is located on both sides of the rotary connector 36.

[0074] The application of the rotary connector 36 allows the carrier plate 31 to flexibly adapt to material boxes 200 of different shapes and sizes, ensuring the stability of the material box 200 during transport. Through the rotary connector 36, the carrier plate 31 can be fine-tuned according to the actual needs of the material box 200, thereby improving the adaptability and flexibility of the transport device 100. The compression spring 37 plays a role in buffering and shock absorption. During lifting, the compression spring 37 can absorb and disperse the impact force generated by the weight or movement of the material box 200, protecting the structure of the lifting part 30 from damage. At the same time, the elastic characteristics of the spring can also offset vibration to a certain extent, improving the smoothness and safety of the transport process. The combined design of the rotary connector 36 and the compression spring 37 also enhances the stability and reliability of the lifting part 30. The rotary connector 36 allows for fine-tuning of the carrier plate 31, while the compression spring 37 provides additional support and stability, jointly ensuring the safety and stability of the material box 200 during transport.

[0075] More preferably, the rotary connector 36 includes a seat bearing 36A and a rotating shaft 36B.

[0076] Two bearing seats 36A are fixedly connected to the support plate 32. Two rotating shafts 36B are rotatably connected between the two bearing seats 36A. Two joint shaft brackets 36C are integrally formed on both sides of each rotating shaft 36B. The joint shaft brackets 36C are fixedly connected to the carrying plate 31, and the carrying plate 31 rotates around the support plate 32.

[0077] The bearing 36A, a key component of the rotary connector 36, is fixedly connected to the support plate 32, providing stable and reliable rotational support for the rotating shaft 36B. The bearing 36A is designed to withstand the weight of the carrying plate 31 and the material box 200, maintaining low friction during rotation to ensure smooth and precise rotational movement. The rotating shaft 36B is rotatably connected between the two bearings 36A, enabling the carrying plate 31 to rotate relative to the support plate 32. The design of the rotating shaft 36B not only meets the rotational adjustment requirements that the material box 200 may need during transport but also ensures the smoothness and continuity of rotational movement. The integrally formed joint brackets 36C on both sides of the rotating shaft 36B are fixedly connected to the carrying plate 31, enhancing the connection strength between the rotary connector 36 and the carrying plate 31. As a transition component between the rotating shaft 36B and the carrying plate 31, the joint brackets 36C can withstand the shear force and bending moment generated during rotation, ensuring the stability and durability of the entire rotary connector 36. Most importantly, this layout allows the carrier plate 31 to rotate flexibly and stably around the support plate 32. Whether adjusting the orientation of the material box 200 to meet processing requirements or optimizing the transfer path to improve efficiency, the rotary connector 36 provides precise and reliable rotational support.

[0078] In this way, by transporting the material box 200 sequentially from the first conveying section 20 to the lifting section 30 along the first direction F1, and then transporting it from the lifting section 30 to the second conveying section 40 along the second direction F2 after the pneumatic section 33 lowers the lifting section 30, with the lifting section 30 located between the first conveying section 20 and the second conveying section 40, the transfer device 100 realizes the vertical transport of the material box 200, effectively improving the transfer efficiency. Furthermore, by adopting the method of partially overlapping the vertical projection of the first conveying section 20 with the vertical projection of the second conveying section 40, the space utilization rate of the transfer device 100 is improved.

[0079] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
