Description

Technical Field

[0001] This utility model relates to the field of spray equipment technology, specifically a rod spray dust removal device. Background Technology

[0002] In industrial production, large-size fastener bars are widely used as important raw materials in various industries such as machinery manufacturing, automotive, and aerospace. These large-size bars typically require surface cleaning before processing to remove dust, oil, and other impurities, ensuring the quality and precision of subsequent processing.

[0003] However, traditional cleaning methods mainly rely on manual rinsing, which has several problems. First, manual rinsing is inefficient and cannot meet the needs of large-scale production, especially when processing large-diameter bars, requiring a significant amount of manpower and time. Second, the cleaning effect of manual rinsing is inconsistent, easily resulting in incomplete cleaning and residual impurities on the bar surface, affecting the quality of subsequent processing. Therefore, developing a high-efficiency, automated spray dust removal device for large-diameter bars has become a critical problem urgently needing to be solved in industrial production.

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0016] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0017] To solve the above technical problems, such as Figure 1-3 As shown, this utility model designs a bar spray dust removal device, including a frame 1. The frame 1 is equipped with a transverse transmission mechanism for transversely transmitting a pallet 2. Specifically, the transverse transmission mechanism includes a sprocket set 3, a chain 4, and a motor 5. Several sprockets of the sprocket set 3 are arranged inside the side plate of the frame 1. The chain 4 is wound around each sprocket of the sprocket set 3. The chain in the figure is straight but is actually a curved part that is not shown. The two sets of chains 4 are symmetrically arranged. The motor 5 is located outside the side plate of the frame 1 and is connected to one of the sprockets to drive it to rotate. The chain 4 drives the sprocket to rotate smoothly, ensuring that the pallet 2 is stably transmitted transversely on the frame 1. This provides a reliable transmission guarantee for the continuous spray dust removal of the bar 6, improving production efficiency and the automation level of the equipment.

[0018] The pallet 2 is provided with several evenly spaced insertion holes along the longitudinal direction. A bar 6 is inserted into the insertion holes, and the head of the bar 6 is located above the pallet 2. The pallet 2 serves as a fixture and can bear a certain amount of products. Through the design of the insertion holes, the bar 6 is accurately positioned. The two sides of the pallet 2 cooperate with the chain through lugs or chain clamps to move synchronously with the chain.

[0019] It also includes a first spraying mechanism 7, a second spraying mechanism 8, and a downward pressure limiting mechanism 9. The frame 1 is evenly spaced along the transverse direction with several spraying zones. Each spraying zone is equipped with a set of first spraying mechanisms 7 and a set of second spraying mechanisms 8. The first spraying mechanism 7 is located above the transmission surface and sprays vertically downwards, while the second spraying mechanism 8 is located below the transmission surface and sprays vertically upwards. Each set of first spraying mechanisms 7 and second spraying mechanisms 8 is staggered, realizing all-round spraying of the upper and lower surfaces of the bar stock 6. It can fully cover the entire surface of the bar stock 6, further improving the uniformity and coverage of the spraying. Moreover, it allows the bar stock 6 to pass through multiple spraying zones in sequence during the transmission process, thereby receiving multiple sprays and ensuring the thoroughness of the spraying.

[0020] In a further preferred embodiment, the first spraying mechanism 7 and the second spraying mechanism 8 have the same structure. The first spraying mechanism 7 includes a main pipe 71, branch pipes 72, and spray pipes 73. The top of the main pipe 71 is connected to the top plate of the frame 1 via a fixing plate. The axis of the main pipe 71 is arranged longitudinally. The main pipe 71 is used to connect with the spray liquid conduction pipeline. A corresponding pump body is provided in the bottom area of ​​the frame 1 to conduct the spray liquid storage tank and make it flow in the spray liquid conduction pipeline. Several branch pipes 72 are symmetrically arranged at both ends of the main pipe 71. Each branch pipe 72 is connected to a spray pipe 73. Through the reasonable layout of the main pipe 71, branch pipes 72, and spray pipes 73, the spray liquid can be sprayed evenly from the spray pipes 73 to form a fine water curtain, which sprays the bar stock 6 in all directions. The spraying mechanism can cover a larger area.

[0021] In a further preferred embodiment, two downward limiting mechanisms 9 are symmetrically arranged before and after each spray zone. Each downward limiting mechanism 9 includes a linear cylinder 91, a guide rod 92, a slider 93, a limiting plate 94, and a positioning seat 95. A support plate 96 is fixedly provided below the top plate of the frame 1, and the support plate 96 is perpendicular to the top plate. The cylinder body of the linear cylinder 91 is fixed to the top plate of the frame 1, and the piston rod of the linear cylinder 91 faces downward and is fixedly connected to the limiting plate 94 through a connecting block. The linear cylinder 91 is used to drive the limiting plate 94 to move up and down. A slider 93 is connected to one side of the limiting plate 94, and the two guide rods 92 are symmetrically arranged from left to right. The limiting plate 94 is set on both sides of the linear cylinder 91 and connected to the support plate 96 through the positioning seat 95. The inner hole of the slider 93 is slidably engaged with the guide rod 92. The linear cylinder 91 drives the limiting plate 94 to move up and down. The action is fast and the positioning is accurate. With the sliding engagement of the slider 93 and the guide rod 92, the movement of the limiting plate 94 is more stable and reliable. When spraying is in progress, the limiting plate 94 moves down to limit the support plate 2 and prevent it from shaking or shifting under the impact of the spray liquid flow, thus ensuring the stability of the support plate 2 and thus ensuring the stability of the bar stock 6. When the support plate 2 is sprayed and continues to move forward with the chain 4, the limiting plate 94 is in the raised state to avoid interference.

[0022] In a further preferred embodiment, a fixed rod 10 is provided on one side of the frame 1, and a control box 11 is provided on the fixed rod 10. The control box 11 is equipped with electrical components and control circuits for controlling the operation of the entire spray dust removal device. The setting of the control box enables the operator to conveniently perform centralized control and operation of the spray dust removal device.

[0023] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
