Description

Technical Field

[0001] This utility model belongs to the field of automatic electrostatic powder coating technology for aluminum profiles, and specifically relates to an automatic feeding device for automatic electrostatic powder coating of aluminum profiles. Background Technology

[0002] Aluminum profiles, such as aluminum tubes, require a series of processing steps during manufacturing, with the spraying step being particularly important. During spraying, the aluminum tubes need to be transported, typically arranged vertically with the top end hanging on a hook. For example, CN216125923U discloses an automatic electrostatic powder coating unloading device for aluminum profiles, including a conveyor body, a connecting plate, and a support frame; the bottom of the conveyor body is connected to the support frame via the connecting plate; and the device also includes the internal components of the support frame, etc. A limiting hole is provided at the interval, and a load-bearing plate is provided inside the limiting hole. The bottom of the load-bearing plate is connected to the bottom of the limiting hole through a connecting spring. Threaded blocks are provided at both ends of the load-bearing plate, and threaded rods are provided inside the threaded blocks. The bottom end of the threaded rod is connected to a rotating rod through an elastic pull rope assembly. A rotating groove is provided on the outer side of one end of the rotating rod. A top rod is provided at one end of the rotating rod, and the top rod extends into the interior of the load-bearing frame through a limiting block. The other end of the top rod is connected to one side of the limiting plate. The upper end of the hook is hung in the limiting hole. The weight of the hook and the aluminum tube causes the load-bearing plate to descend, driving the connecting spring. At the same time, threaded blocks are set on both the left and right ends of the load-bearing plate. During the descent of the threaded blocks, the threaded rod will rotate. As the threaded rod rotates, it will drive the rotating rod to rotate through the elastic pull rope assembly. This rotating rod will drive the top rod to move through the limiting block. During the movement of the limiting block, the limiting plate will limit the hook. Through the above settings, the hook will be prevented from shifting during the movement of the load-bearing frame.

[0003] However, due to the friction between the threaded rod and the threaded block, the threaded rod has a self-locking function, maintaining its displacement under load. Therefore, the weight of the hook and the aluminum tube makes it difficult for the threaded rod to rotate. If the threaded rod cannot rotate, the limiting block cannot move to restrain and limit the hook, and the hook will still deviate during movement. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an automatic electrostatic powder coating and automatic feeding device for aluminum profiles. By placing one end of a hook inside a rectangular frame and hanging it on a load-bearing plate, and placing an aluminum tube on the other end of the hook, the load-bearing plate moves downward under the action of gravity. The second gear rotates, driving the first gear to rotate, and the first gear drives the first rack to move, causing the two limiting plates to move towards each other, clamping the hook and limiting its movement. This prevents the hook from rotating during the movement of the rectangular frame.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An automatic electrostatic powder coating and automatic unloading device for aluminum profiles includes:

[0007] A rectangular frame, wherein a load-bearing plate is provided on the inner side of the rectangular frame along the horizontal direction, and a spring arranged vertically is fixedly connected between the load-bearing plate and the bottom of the rectangular frame;

[0008] A limiting plate is symmetrically arranged vertically on the upper end of the load-bearing plate. A first rack arranged horizontally is fixedly connected to the outer side of the limiting plate. A first gear is meshed with the lower end of the first rack. A second gear is fixedly connected to the side of the first gear. A second rack arranged vertically is meshed with the side of the second gear. The lower end of the second rack is fixedly connected to the bottom of the rectangular frame.

[0009] The principles and technical effects of the above technical solution are as follows:

[0010] By placing one end of the hook inside the rectangular frame and hanging it on the load-bearing plate, and then placing the aluminum tube on the other end of the hook, the load-bearing plate moves down under the action of gravity. The second gear rotates, which drives the first gear to rotate. The first gear drives the first rack to move, causing the two limiting plates to move towards each other, clamping the hook and limiting its position. This prevents the hook from rotating during the movement of the conveyor body and the rectangular frame.

[0011] In a preferred embodiment, the present invention can be further configured as follows: support plates are provided on both sides of the first gear, the lower end of the support plate is fixedly connected to the end of the load-bearing plate, and a gear shaft coaxially arranged is fixedly connected to the first gear, with both ends of the gear shaft rotatably connected to the support plates.

[0012] In a preferred embodiment, the present invention can be further configured such that one end of the gear shaft extends outward and is fixedly connected to the second gear.

[0013] In a preferred embodiment, the present invention can be further configured such that: a fixing block is fixedly connected between the top ends of the two support plates at the same end of the load-bearing plate, and a first sliding rod arranged in a transverse direction is slidably connected to the fixing block, with one end of the first sliding rod fixedly connected to the limiting plate.

[0014] In a preferred embodiment, the present invention can be further configured such that the other end of the first slide bar is fixedly connected to the first rack.

[0015] In a preferred embodiment, the present invention can be further configured such that: a second sliding rod is fixedly connected to the lower end of the load-bearing plate, and the lower end of the second sliding rod penetrates the bottom of the rectangular frame, so that the second sliding rod is slidably connected to the bottom of the rectangular frame.

[0016] In a preferred embodiment, the present invention can be further configured such that a baffle is fixedly connected to the lower end of the second slide bar.

[0017] In a preferred embodiment, the present invention can be further configured such that the spring is sleeved on the second slide rod.

[0018] In a preferred embodiment, this utility model may be further configured as follows: it also includes a conveying guide rail, on which a connecting frame is fixedly connected, and bolts are fixedly connected to both sides of the lower end of the connecting frame. Ear plates are fixedly connected to both sides of the upper end of the rectangular frame, and through holes are provided on the ear plates. The bolts pass through the through holes and are threadedly connected to nuts.

[0019] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows:

[0020] A fixed connection refers to a connection in which parts or components are fixed in place, with no relative movement between them. These connections are divided into two types: detachable and non-detachable.

[0021] (1) Detachable connections use screws, splines, wedges, etc. to fix parts together. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of bolts, keys, wedges) and properly tightened.

[0022] (2) Non-removable connections mainly refer to welding, riveting, and tenon joints. Since disassembly is required by forging, sawing, or oxy-acetylene cutting during repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to the process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.

[0023] A threaded connection is a detachable connection in which threaded parts (or the threaded portion of the connected parts) are joined together to form a single unit.

[0024] A sliding connection refers to two objects that are in contact but not fixed, and can slide relative to each other.

[0025] A rotating connection is a connection between parts that allows the parts to rotate relative to each other.

[0026] The beneficial effects of this utility model are:

[0027] By placing one end of the hook inside the rectangular frame and hanging it on the load-bearing plate, and then placing the aluminum tube on the other end of the hook, the load-bearing plate moves down under the action of gravity. The second gear rotates, which drives the first gear to rotate. The first gear drives the first rack to move, causing the two limiting plates to move towards each other, clamping the hook and limiting its movement. This prevents the hook from rotating during the movement of the rectangular frame. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0034] Based on the concept of this application, combined with Figures 1 to 3This describes an embodiment of an automatic electrostatic powder coating and automatic unloading device for aluminum profiles. Specifically, the automatic electrostatic powder coating and automatic unloading device for aluminum profiles is constructed as a split structure, which has a rectangular frame 1, a load-bearing plate 2, a limiting plate 4, a first rack 5, a first gear 6, a second gear 7, and a second rack 8 that cooperate with each other. By placing one end of the hook 20 inside the rectangular frame 1 and hanging it on the load-bearing plate 2, when the other end of the hook 20 is placed on the aluminum tube, the load-bearing plate 2 moves downward under the action of gravity. The second gear 7 rotates, driving the first gear 6 to rotate. The first gear 6 drives the first rack 5 to move, causing the two limiting plates 4 to move towards each other, clamping the hook 20 and limiting the hook 20, thereby preventing the hook 20 from rotating during the movement of the rectangular frame 1.

[0035] like Figure 1-3 As shown, the automatic electrostatic powder coating and automatic unloading device for aluminum profiles includes:

[0036] A rectangular frame 1 has a load-bearing plate 2 arranged horizontally on the inner side of the rectangular frame 1, and a spring 3 arranged vertically is fixedly connected between the load-bearing plate 2 and the bottom of the rectangular frame 1.

[0037] A limiting plate 4 is symmetrically arranged vertically on the upper end of the load-bearing plate 2. A first rack 5 arranged horizontally is fixedly connected to the outer side of the limiting plate 4. A first gear 6 is meshed with the lower end of the first rack 5. A second gear 7 is fixedly connected to the side of the first gear 6. A second rack 8 arranged vertically is meshed with the side of the second gear 7. The lower end of the second rack 8 is fixedly connected to the bottom of the rectangular frame 1.

[0038] By placing one end of the hook 20 inside the rectangular frame 1 and hanging it on the load-bearing plate 2, when the other end of the hook 20 is placed with an aluminum tube, the load-bearing plate 2 moves down under the action of gravity. The second gear 7 rotates, driving the first gear 6 to rotate. The first gear 6 drives the first rack 5 to move, causing the two limiting plates 4 to move towards each other, clamping the hook 20 and limiting the hook 20, thereby preventing the hook 20 from rotating during the movement of the rectangular frame 1.

[0039] In one embodiment of this utility model, support plates 9 are provided on both sides of the first gear 6. The lower end of the support plate 9 is fixedly connected to the end of the load-bearing plate 2. A gear shaft 10 coaxially arranged is fixedly connected to the first gear 6, and both ends of the gear shaft 10 are rotatably connected to the support plate 9. The support plates 9 are provided to support and stabilize the rotation of the first gear 6.

[0040] In one embodiment of this invention, one end of the gear shaft 10 extends outward and is fixedly connected to the second gear 7, thereby achieving synchronous rotation of the first gear 6 and the second gear 7.

[0041] In one embodiment of this utility model, a fixing block 11 is fixedly connected between the top ends of two support plates 9 at the same end of the load-bearing plate 2. A first sliding rod 12 arranged laterally is slidably connected to the fixing block 11, and one end of the first sliding rod 12 is fixedly connected to the limiting plate 4.

[0043] In one embodiment of this utility model, a second sliding rod 13 is fixedly connected to the lower end of the load-bearing plate 2. The lower end of the second sliding rod 13 passes through the bottom of the rectangular frame 1, so that the second sliding rod 13 is slidably connected to the bottom of the rectangular frame 1, ensuring that the load-bearing plate 2 can move up and down without shifting.

[0044] In one embodiment of this utility model, a baffle 14 is fixedly connected to the lower end of the second slide bar 13. The baffle 14 prevents the second slide bar 13 from detaching from the rectangular frame 1, so that the load-bearing plate 2 will not detach from the rectangular frame 1 when the hook 20 is not attached.

[0045] In one embodiment of this utility model, the spring 3 is sleeved on the second slide rod 13. This arrangement can prevent the spring 3 from bending under force. At the same time, when the hook 20 needs to be removed, during the upward movement of the hook 20, the elastic force of the spring 3 pushes the load-bearing plate 2 upward, the second gear 7 rotates and drives the first gear 6 to rotate, the first gear 6 drives the first rack 5 to move, so that the two limiting plates 4 move in opposite directions.

[0046] In one embodiment of this utility model, a conveying guide rail 15 is further included. A connecting frame 16 is fixedly connected to the conveying guide rail 15. Bolts 17 are fixedly connected to both sides of the lower end of the connecting frame 16. Ear plates 18 are fixedly connected to both sides of the upper end of the rectangular frame 1.
