A quick drying device for painting aluminum products

Abstract

This utility model relates to the field of aluminum product paint drying technology, specifically, to a rapid drying device for aluminum product painting. It includes an oven with an opening on one side, and several trays arranged in a vertical array inside the oven. All trays are horizontally stacked at predetermined intervals, and several suspension components are provided at the bottom of the trays. In this utility model, when the hook is rotated to a vertical position, the locking block of the locking component automatically inserts into the corresponding slot of the convex ring under the action of a return spring, firmly locking the rotating rod and the hook. At this time, the hook is exposed between adjacent trays, enabling stable suspension of perforated irregularly shaped aluminum products for drying. When the hook is rotated to a horizontal position, the locking block automatically inserts into another slot of the convex ring under the action of a return spring, locking it completely, so that the hook is completely stored in the storage slot at the bottom of the tray. This avoids the hook occupying the vertical space between the trays, making it convenient for operators to place flat aluminum products directly on the tray surface for drying.

Description

Technical Field

[0001] This utility model relates to the field of aluminum product paint drying technology, specifically, to a rapid drying device for aluminum product processing and painting. Background Technology

[0002] Current drying processes for painted aluminum products generally rely on oven equipment. However, traditional ovens typically only have flat material trays, designed specifically for flat workpieces. When dealing with small, irregularly shaped aluminum workpieces (such as tubular parts or parts with complex geometries) that require full-body painting, there is a lack of a solution that can effectively fix and suspend the workpiece while ensuring the integrity of the paint film. This directly leads to multiple difficulties when drying irregularly shaped parts: either they cannot fit into the oven due to their size or shape; or they are forced to lie flat on the tray surface, causing the wet paint to come into contact with and stick to the tray, resulting in surface defects such as paint film damage and peeling. If a separate hanging method is used, it requires a lot of space inside the oven, resulting in low drying efficiency, high risk of paint damage, and difficulty in guaranteeing product qualification rate.

[0003] To solve the problem of suspending irregularly shaped parts, an intuitive solution is to add hooks to the bottom of existing material pallets. However, this solution introduces a new problem: when the oven processes regular flat workpieces, the hooks at the bottom of the pallet will protrude downwards, hindering the reasonable stacking spacing of the material pallets, compressing the effective loading height, and reducing the utilization rate of the oven's internal space. If a strategy of equipping flat parts and irregularly shaped parts with dedicated pallets (i.e., hookless pallets and hooked pallets) is adopted, the pallets inside the oven need to be changed frequently. This is not only cumbersome and time-consuming, affecting the production cycle, but also requires the additional preparation and management of two sets of pallets, leading to increased equipment investment and warehousing costs, and causing unnecessary waste of resources. Utility Model Content

[0004] The purpose of this invention is to provide a rapid drying device for painting aluminum products, in order to solve the problems mentioned in the background art. To solve the problem of hanging irregularly shaped parts, if a strategy of equipping flat parts and irregularly shaped parts with dedicated trays is adopted, the trays inside the oven need to be changed frequently, which is cumbersome and time-consuming.

[0005] To address the above problems, the present invention aims to provide a rapid drying device for aluminum product processing and painting, comprising an oven with an opening on one side. Several trays are arranged in a vertical array inside the oven, and all trays are horizontally stacked at predetermined intervals. Several suspension components are provided at the bottom of each tray. Each suspension component includes an embedded groove formed in the lower side wall of the tray. Several storage slots are arranged in a horizontal array on one side of the embedded groove. A rotating rod is rotatably mounted inside the embedded groove. Hooks are provided on the circumferential side wall of the rotating rod at positions corresponding to each storage slot. When the rotating rod drives the hook to a horizontal position, the hook is stored in the corresponding storage slot. When the rotating rod drives the hook to a vertical position, the hook rotates between two adjacent trays. The suspension component also includes a locking component located on the side of the tray near the oven opening. When the rotating rod drives the hook to a horizontal or vertical position, the locking component locks the position of the rotating rod.

[0006] As a further improvement to this technical solution, the end of the rotating rod near the opening of the oven rotates through the side wall of the embedded groove and extends to the outside of the tray, and a bolt head is coaxially fixedly connected to this end.

[0007] As a further improvement to this technical solution, the locking assembly includes a convex ring coaxially fixedly connected to the rotating rod, the convex ring being located between the bolt head and the outer wall of the tray.

[0008] As a further improvement to this technical solution, two slots are provided on the circumferential sidewall of the convex ring, and the included angle between the two adjacent slots is 90 degrees.

[0009] As a further improvement to this technical solution, the locking component also includes a locking block that is slidably disposed on one side of the tray. When the rotating rod drives the hook to rotate to a horizontal or vertical state, the convex ring rotates with the rotating rod, so that the position of one of the locking slots corresponds to the position of the locking block.

[0010] As a further improvement to this technical solution, the locking assembly also includes a positioning plate fixedly installed on one side of the tray, and two slide rods are symmetrically fixedly connected on the side of the locking block away from the convex ring, with the other end of the slide rods sliding through the positioning plate and extending outward.

[0011] As a further improvement to this technical solution, a return spring sleeved on the slide rod is provided between the positioning plate and the locking block, and the return spring pushes the locking block away from the positioning plate.

[0012] As a further improvement to this technical solution, several horizontally arranged baffles are vertically arrayed and fixedly installed on the two opposite inner walls of the oven, and the two ends of the lower side wall of the tray are respectively supported on the two baffles located at the same height.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This rapid drying device for aluminum product processing and painting: When the hook is rotated to the vertical position, the locking block of the locking component automatically inserts into the corresponding slot of the convex ring under the action of the return spring, firmly locking the rotating rod and the hook. At this time, the hook is exposed between adjacent trays, which can stably suspend irregularly shaped aluminum products with holes for drying. When the hook is rotated to the horizontal position, the locking block automatically inserts into another slot of the convex ring under the action of the return spring, locking it so that the hook is completely stored in the storage slot at the bottom of the tray, thereby avoiding the hook from occupying the vertical space between the trays, making it convenient for operators to place flat aluminum products directly on the tray surface for drying.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figures 1-3 As shown, the purpose of this embodiment is to provide a rapid drying device for aluminum product processing and painting, including an oven 1 with an opening on one side. The oven 1 is a commercially available mature product, and its working principle will not be described in detail here. Several trays 2 are arranged in a vertical array inside the oven 1. The trays 2 are used to place aluminum products to be dried. All trays 2 are stacked horizontally at a predetermined interval. The distance between two adjacent trays 2 is greater than the thickness of the aluminum products to be dried, so as to facilitate the flow of hot air. In order to ensure that the hot air can effectively pass through each layer of trays 2, several vertically penetrating ventilation slots 21 are provided in a rectangular array on the trays 2.

[0018] To fix the position of the tray 2 and keep it horizontal, several horizontally arranged baffles 11 are vertically arrayed and fixed on the two opposite inner walls of the oven 1. The two ends of the lower side wall of the tray 2 are respectively placed on two baffles 11 at the same height.

[0019] For flat aluminum products that only require painting on one side, the operation process is as follows: Place multiple aluminum products to be dried with the painted side facing up on each tray 2, ensuring that the painted side does not contact the inner wall of the oven 1 and the tray 2 to avoid damage to the paint surface. Then close the door of the oven 1 and start the oven 1. The hot airflow generated by the oven 1 blows over the painted surface of the aluminum products, heating the aluminum products through heat exchange, thereby accelerating the drying of the paint surface.

[0020] To facilitate the drying of irregularly shaped aluminum products that have been fully painted, refer to Figure 4 and Figure 5 Several suspension components 3 are provided at the bottom of the tray 2. Each suspension component 3 includes an embedded groove 31 formed in the lower side wall of the tray 2. Several storage slots 32 are arranged horizontally on one side of the embedded groove 31. A rotating rod 33 is rotatably installed inside the embedded groove 31. A hook 34 is provided on the circumferential side wall of the rotating rod 33 at a position corresponding to each storage slot 32. (Refer to...) Figure 9 When the rotating rod 33 drives the hook 34 to rotate to a vertical state, the hook 34 rotates between two adjacent trays 2, and at this time the hook 34 is in a suspended state.

[0021] During operation, holes need to be pre-drilled in the irregular aluminum product before spraying. Then, iron wire or high-temperature resistant rope is passed through the holes and knotted to form a loop. Finally, this loop rope is hung on the vertical hook 34, so that the irregular aluminum product can be suspended under the tray 2 and the paint surface of the aluminum product is dried using the oven 1.

[0022] Operators can adjust the spacing between two adjacent trays 2 by placing the tray 2 on the baffles 11 at different heights according to the length of the irregularly shaped aluminum product, so as to ensure that the lower end of the suspended aluminum product does not contact the tray 2 below, thereby protecting the paint surface from damage.

[0023] To enhance the stability of aluminum products in the suspended state, the suspension assembly 3 also includes a locking assembly 36 located on the side of the tray 2 near the opening of the oven 1. When the rotating rod 33 drives the hook 34 to rotate to a horizontal or vertical state, the locking assembly 36 is used to lock the position of the rotating rod 33, thereby restricting the rotation of the hook 34.

[0024] When there is no need to hang irregularly shaped aluminum products, the rotating rod 33 can be rotated to make the hook 34 horizontal. At this time, the hook 34 is stored in the corresponding storage slot 32. When the hook 34 is in the stored state, the locking component 36 will restrict the hook 34 from rotating out of the storage slot 32, so as to prevent the hook 34 from occupying the space between two adjacent trays 2, thus making it convenient for the operator to place the flat workpiece directly on the upper side wall of the tray 2 for drying.

[0025] The end of the rotating rod 33 near the opening of the oven 1 rotates through the side wall of the embedded groove 31 and extends to the outside of the tray 2. A bolt head 35 is coaxially fixed to this end, making it convenient for operators to use wrenches or other tools to rotate the rotating rod 33.

[0026] The structure of locking component 36 is detailed below, refer to Figures 6-8 The locking assembly 36 includes a convex ring 361 coaxially fixedly connected to the rotating rod 33. The convex ring 361 is located between the bolt head 35 and the outer side wall of the tray 2. Two slots 362 are opened on the circumferential side wall of the convex ring 361, and the included angle between the two adjacent slots 362 is 90 degrees.

[0027] The locking assembly 36 also includes a locking block 363 slidably disposed on one side of the tray 2. A slider is fixedly connected to the side of the locking block 363 near the tray 2. A groove is provided on the tray 2 at the position corresponding to the slider. The slider is slidably disposed in the corresponding groove. The slider and the groove cooperate to restrict the locking block 363 to move only horizontally. The locking assembly 36 also includes a positioning plate 364 fixedly installed on one side of the tray 2. Two slide rods 365 are symmetrically fixedly connected to the side of the locking block 363 away from the protruding ring 361. The other end of the slide rod 365 slides through the positioning plate 364 and extends outward, further restricting the locking block 363 to move only horizontally along the axis of the slide rod 365. A return spring 366 sleeved on the slide rod 365 is provided between the positioning plate 364 and the locking block 363. The return spring 366 pushes the locking block 363 away from the positioning plate 364.

[0028] When the rotating rod 33 drives the hook 34 to rotate to a horizontal or vertical state, the convex ring 361 rotates with the rotating rod 33, so that the position of one of the slots 362 corresponds to the position of the block 363. At this time, the return spring 366 rebounds and pushes the block 363 away from the positioning plate 364, so that the end of the block 363 is inserted into the corresponding slot 362. The block 363 and the slot 362 cooperate to restrict the rotation of the convex ring 361, thereby restricting the rotation of the rotating rod 33 and the hook 34.

[0029] When the rotating rod 33 drives the hook 34 to a horizontal position (with the locking block 363 inserted into one of the slots 362), if it is necessary to rotate the hook 34 to a vertical position, the operator needs to push the locking block 363 towards the positioning plate 364. This reduces the distance between the locking block 363 and the positioning plate 364, causing the return spring 366 to compress and contract until the locking block 363 moves out of the slot 362. Then, the operator rotates the rotating rod 33 to misalign the slot 362 on the convex ring 361 with the locking block 363. At this point, the locking block 363 is released, and the return spring 366 immediately... The spring rebounds, pushing the locking block 363 closer to the convex ring 361, so that its end abuts against the circumferential side wall of the convex ring 361. Continue to rotate the rotating rod 33 to bring the hook 34 to a vertical state. During this process, another slot 362 on the convex ring 361 will rotate to a position aligned with the locking block 363. The return spring 366 then pushes the locking block 363 further closer to the convex ring 361, so that its end automatically inserts into the currently aligned slot 362, thereby locking the hook 34 in a vertical state. When it is necessary to lock the hook 34 back to a horizontal state, the above operation can be repeated.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
