Description

Technical Field

[0001] This application relates to the field of profile processing, and in particular to a loading and unloading device for composite material profiles. Background Technology

[0002] Profiles refer to straight strips with a specific cross-sectional shape and size, formed through plastic processing. They are objects with a certain geometric shape made of iron or steel and other materials with a certain strength and toughness through processes such as rolling, extrusion, and casting. These materials have fixed external dimensions, a specific cross-sectional shape, and certain mechanical and physical properties. Profiles can be used alone or further processed into other manufactured products. They are commonly used in building structures and manufacturing and installation. Mechanical engineers can select the specific shape, material, heat treatment state, mechanical properties, and other parameters of the profile according to design requirements. Then, the profile is divided according to specific size and shape requirements, and further processed or heat-treated to achieve the design precision requirements. During production, profiles need to be cut, drilled, and assembled by installing corner brackets. The finished profiles can then be further assembled into various required profile products using the installed corner brackets.

[0003] Before processing, profiles are typically stacked in a material frame. Before processing, the profiles need to be removed from the frame, positioned as required, and then transported to the processing equipment. This process is generally called loading. Currently, loading is primarily done manually. However, due to the considerable length of the profiles, workers find it strenuous to move them onto the processing equipment, resulting in low efficiency and high labor intensity for workers in existing profile loading operations.

[0004] After the profiles are formed, they need to be painted. In the existing production process, electrostatic spraying is used to paint the surface of the profiles. Electrostatic spraying uses a grounded object as the anode and a high-voltage grid as the cathode. A negative high voltage is applied, forming a high-voltage electrostatic field between the two electrodes. The cathode generates corona discharge, which charges the sprayed paint particles and further atomizes them. According to the principle of like charges repelling and unlike charges attracting, the charged paint particles are attracted to the object along the electric field lines under the influence of the electrostatic field. After discharge, they adhere to the object.

[0005] Before painting, the profiles must be erected and hung on the transmission equipment, and the profiles need to be electrically connected to the transmission equipment to ensure that the profiles are grounded. However, since the profiles are very long, it is very inconvenient for workers to hang them, which greatly affects work efficiency. In order to ensure a reliable connection between the profiles and the hooks and to achieve electrical conductivity, workers need to spend a lot of time tightening the connection between the hooks and the profiles, which is time-consuming and labor-intensive, and greatly affects the painting efficiency.

[0006] In the existing production process, the paint is sprayed first, then leveled, and then dried. Because the drying temperature is high, the paint on the surface is dried first, while the paint inside is still fluid. After the paint inside dries, the surface may crack, resulting in poor drying effect.

[0007] Based on the above, this utility model proposes a loading and unloading device for composite material profiles, which can effectively solve one or more of the above problems. Summary of the Invention

[0009] To achieve the above objectives, this application adopts the following technical solution:

The conveying structure includes a frame and at least two parallel conveyor belts on the frame. The handling structure is located at one end of the conveyor belts. The handling structure includes a carrier plate for placing the profiles. At least one of the conveying structure and the handling structure is connected to a lifting structure, which can drive the carrier plate to rise or fall.

[0011] Preferably, the lifting structure is connected to the side of the frame near the transport structure. The lifting structure includes a lifting drive and a lifting plate. The lifting drive can drive the lifting plate to move in the vertical direction, and the lifting plate can be connected to the carrying plate and drive the carrying plate to move synchronously when moving.

[0012] Preferably, the lifting structure further includes a guide rod, and the lifting plate has a guide hole for embedding the guide rod.

[0013] Preferably, a support plate is connected to the side of the lifting plate away from the frame. The support plate can abut against the conveying structure and follow the vertical movement of the lifting plate to drive the load plate to rise or fall.

[0014] Preferably, the pallet extends at an angle away from the frame, and during the extension process, the side of the pallet away from the frame gradually moves away from the lifting plate in the vertical direction.

[0015] Preferably, the transport structure includes a frame, the carrying plate is connected to the top surface of the frame, and wheels are connected to the side of the frame away from the carrying plate.

[0016] Preferably, the frame is further connected to at least two stops on each side in its width direction, the stops being able to prevent the profile from falling off the handling structure.

[0017] Preferably, the bottom of the stop bar is connected to the frame via a bar seat. The bar seat includes a connecting plate and a connecting cylinder.

[0029] In the description of this utility model, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are merely used for distinction in description and have no special meaning.

[0030] like Figures 1 to 3 As shown, this application provides a loading and unloading device for composite material profiles, including a conveying structure 1 and a handling structure 2. The conveying structure 1 includes a frame 11 and at least two parallel conveyor belts 12 on the frame 11. The handling structure 2 is disposed at one end of the conveyor belts 12. The handling structure 2 includes a carrying plate 21 for placing the profile. At least one of the conveying structure 1 and the handling structure 2 is connected to a lifting structure 3, which can drive the carrying plate 21 to rise or fall.

[0031] In this application, the conveying structure 1 is used to transport the profile from one side of the frame 11 to the opposite side, the handling structure 2 is used to transfer the profile between various workstations, and the lifting structure 3 is used to drive the carrying plate 21 to rise or fall, which makes it convenient for workers to transfer the profile between the handling structure 2 and the conveyor belt 12, effectively reducing the difficulty of transfer, reducing the amount of labor required for transfer, and improving the transfer efficiency, thereby improving the loading and unloading efficiency of the profile.

[0032] The lifting structure 3 is connected to the side of the frame 1 near the transport structure 2. The lifting structure 3 includes a lifting drive 31 and a lifting plate 32. The lifting drive 31 can drive the lifting plate 32 to move in the vertical direction, and the lifting plate 32 can be connected to the carrying plate 21 and drive the carrying plate 21 to move synchronously when moving.

[0033] In other embodiments, the lifting structure 3 can also be provided on the transport structure 2, for example, a scissor lift structure is provided below the loading plate 21.

[0034] Furthermore, the lifting structure 3 also includes a guide rod 33, and the lifting plate 32 has a guide hole 321 for embedding the guide rod 33.

[0035] With the cooperation of guide rod 33 and guide hole 321, lifting plate 32 can only move up and down, and will not rotate or perform other actions, ensuring the smooth progress of the lifting process.

[0036] Furthermore, a support plate 34 is connected to the side of the lifting plate 32 away from the frame 11. The support plate 34 can abut against the conveying structure 2 and follow the vertical movement of the lifting plate 32 to drive the load plate 21 to rise or fall.

[0037] The separate design of the lifting plate 32 and the pallet 34 allows for detachable or movable connections such as rotation and sliding, avoiding interference with other work when the lifting structure 3 is not in use. Furthermore, if an integrated plate is used, the entire plate needs to be replaced if it is damaged. However, the lifting plate 32 is not easily damaged during use, while the pallet 34 may bend due to the excessive weight of the transport structure 2 and the profile. Therefore, the lifting plate 32 and the pallet 34 are designed separately in this application, which can reduce maintenance difficulty and cost.

[0038] Furthermore, the pallet 34 extends at an angle away from the frame 11, and during the extension process, the side of the pallet 34 away from the frame 11 gradually moves away from the lifting plate 32 in the vertical direction.

[0039] The extension length must be sufficient to ensure that the center of gravity of the transport structure 2 falls within the projection of the pallet 34, so as to ensure that the transport structure 2 will not detach from the pallet 34 during the lifting process; the side of the pallet away from the frame 11 is tilted upward, which can better ensure that the transport structure 2 will not detach from the pallet 34 during the lifting process.

[0040] Furthermore, the transport structure 2 includes a frame 22, a carrying plate 21 connected to the top surface of the frame 22, and wheels 23 connected to the side of the frame 22 facing away from the carrying plate 21.

[0041] The frame 22 provides sufficient structural strength for the load plate 21, making it less prone to bending or breakage during lifting and handling.

[0042] Furthermore, at least two baffles 24 are connected to both sides of the frame 22 in the width direction, and the baffles 24 can prevent the profile from falling off the transport structure 2.

[0043] The baffle 24 ensures that the profile will not fall off the transport structure 2 during the transport process.

[0044] Furthermore, the bottom of the stop bar 24 is connected to the frame 22 via a bar seat 25. The bar seat 25 includes a connecting plate 251 and a connecting cylinder 252. The connecting plate 251 is fixedly connected to the frame 22 and is fixedly connected to the side of the connecting cylinder 252. The connecting cylinder 252 is provided with a mounting groove for accommodating part of the stop bar 24.

[0045] In other embodiments, the connecting plate 251 and the connecting cylinder 252 can be rotatably connected to facilitate the retraction of the stop bar; the stop bar 24 and the connecting cylinder 252 can be placed directly, or threaded, or fastened with side bolts, buckles, etc.; the rod seat 25 facilitates the disassembly and assembly of the stop bar 24, optimizing the user experience.

[0046] Furthermore, a pusher assembly 26 is also provided on one side of the frame 22 along its length. The pusher assembly 26 includes a push rod 261 and two vertical poles 262. The bottom ends of the two poles 262 are fixedly connected to the frame 22, and the top ends of the two poles 262 are respectively connected to the two ends of the push rod 261. A baffle 263 is also connected between the two poles 262.

[0047] The push handle assembly 26 facilitates the pushing and pulling of the structure 2 and the transfer of profiles; the baffle 263 prevents the profiles from sliding along the length of the frame 22 and also plays an auxiliary role in alignment.

[0048] Furthermore, at least two guide bars 13 are connected to the side of the frame 11 near the conveyor structure 2. The side of the guide bar 13 away from the frame 11 can abut against the conveyor structure 2 during the conveying process. The top surface of the guide bar 13 is not lower than the top surface of the conveyor belt 12 in the vertical direction. An arc-shaped first guide surface 131 is formed on the side of the top surface of the guide bar 13 away from the frame 11. An inclined second guide surface 132 is formed on the side of the top surface of the guide bar 13 near the frame 11. The second guide surface 132 extends inclinedly towards the frame 11. During the extension process, the side of the second guide surface 132 near the frame 11 gradually moves downward in the vertical direction, and at least part of the second guide surface 132 is lower than the top surface of the conveyor belt 12 in the vertical direction.

[0049] The first guide surface 131 facilitates the transfer of the profile to the conveyor belt 12 on the frame 11, and the second guide surface 132 facilitates the conveying of the profile to the top surface of the guide bar, thereby facilitating its transfer into the handling structure 2.
