Description

Technical Field

[0001] This utility model relates to the technical field of metal surface treatment equipment, and in particular to a metal base plate sandblasting treatment equipment. Background Technology

[0002] Sandblasting is a common surface strengthening and cleaning process in the manufacturing of metal base plates. It uses high-speed jets of abrasive to impact the surface of the workpiece to remove impurities such as oxide scale and rust, and to create a uniform roughness, providing a good foundation for subsequent coating and other processes.

[0003] In existing sandblasting operations, in order to adapt to metal base plates of different specifications and shapes, it is often necessary to adjust the spray angle and direction of the spray gun to ensure comprehensive processing coverage and uniform effect. However, many sandblasting equipment currently have a relatively primitive design in terms of angle adjustment. Operators usually need to stop the machine and enter the equipment to manually adjust and tighten it. This process is not only cumbersome, time-consuming and labor-intensive, but also difficult to guarantee the accuracy of adjustment. Especially when facing large-volume and multi-model production tasks, frequent manual adjustments seriously restrict the overall production efficiency.

[0004] Furthermore, after sandblasting, the surface of the metal base plate will be covered with a large amount of residual abrasive (i.e., sand) and metal fragments impacted from the impact. Currently, the treatment of these mixed wastes is relatively crude, mostly using manual blowing or brushing to clean them, and then treating the mixture as waste. This method has obvious shortcomings: First, manual cleaning adds extra labor steps and reduces the automation level of the production line; second, a large part of the waste sand is still recyclable, and discarding it along with the metal fragments results in a huge waste of production raw materials, which increases production costs; finally, the dust generated during the cleaning process can easily cause secondary pollution to the production workshop environment.

[0005] Therefore, this utility model proposes a metal base plate sandblasting equipment to overcome the shortcomings of the prior art. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Example:

[0031] Please refer to Figures 1 to 4 This utility model provides a metal base plate sandblasting equipment, which aims to solve the problems of inconvenient angle adjustment of the spray gun 2078, low efficiency, and difficulty in effectively separating and recycling sandblasting waste in the prior art.

[0032] like Figure 1 As shown, the metal base plate sandblasting equipment includes a shell 1, a conveyor belt 5, an angle adjustment mechanism 2, a sand cleaning mechanism 3, a curtain 4, and a control panel 6. The shell 1 forms the main frame of the equipment and creates a closed working space. The conveyor belt 5 runs through the length of the shell 1 and is used to automatically transport metal base plates. The angle adjustment mechanism 2 and the sand cleaning mechanism 3 are both located inside the shell 1. The curtain 4 is located at the material inlet and outlet of the shell 1 and is used to prevent internal sand from splashing outward when the conveyor belt 5 transports the workpiece. The control panel 6 is located outside the shell 1 and is used to operate and control the entire equipment.

[0033] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the angle adjustment mechanism 2 and the sand cleaning mechanism 3 of the metal base plate sandblasting equipment have a specific structural cooperation and connection relationship.

[0034] Please refer to the following carefully. Figure 2 and Figure 3 The structure of the angle adjustment mechanism 2 will be described in detail below:

[0035] The angle adjustment mechanism 2 includes a device box 201, a rotating component for horizontal rotation of the spray gun 2078, and an adjustment component 207 for pitching and tilting the spray gun 2078. The motor 202 of the rotating component and the electric push rod 2071 of the adjustment component 207 are both electrically connected to the control panel 6. The rotating component includes a double-layer circular plate 204. The bottom circular plate of the double-layer circular plate 204 is rotatably mounted on the device box 201 through a bearing 206. A gear ring 205 is fixedly connected to the outer periphery of the upper circular plate of the double-layer circular plate 204. A gear 203 is fixedly connected to the output end of the motor 202. The gear 203 meshes with the gear ring 205 for transmission. The adjustment component 207 is mounted above the double-layer circular plate 204 and rotates with it.

[0036] The adjustment assembly 207 includes a fixed plate 2072, a rotating plate 2076, a third rotating shaft 2077, an electric push rod 2071 for driving, and a linkage mechanism. The fixed plate 2072 is fixed on the double-layer circular plate 204. The rotating plate 2076 is pivotally connected to the bottom of the fixed plate 2072 through the third rotating shaft 2077. The spray gun 2078 is fixedly connected to the rotating plate 2076. The linkage mechanism includes a first rotating shaft 2073, a connecting plate 2074, and a second rotating shaft 2075. The output end of the electric push rod 2071 is connected to the first rotating shaft 2073. The two ends of the first rotating shaft 2073 are rotatably connected to one end of the connecting plate 2074. The other end of the connecting plate 2074 acts on the second rotating shaft 2075, which is rotatably connected to the rotating plate 2076, thereby converting the linear motion of the electric push rod 2071 into the oscillation of the rotating plate 2076.

[0037] Please refer to the following carefully. Figure 4 The structure of the sand cleaning mechanism 3 will be described in detail below:

[0038] The sand cleaning mechanism 3 includes a dust collector 301, a suction pipe 302, an exhaust pipe 305, a support plate 303, a dust suction port 304, a collection box 306, a magnet 307, and a drawer 308. The dust suction port 304 is located above the end of the conveyor belt 5 and is connected to the suction pipe 302. The suction pipe 302 and the exhaust pipe 305 are both fixedly connected by the support plate 303. The dust collector 301 is connected to the suction pipe 302 through a pipe to generate suction. Waste is transported to the collection box 306 through the suction pipe 302 and the exhaust pipe 305. A magnet 307 is fixedly installed on the inner side wall of the collection box 306. A drawer 308 is detachably installed at the bottom of the collection box 306 and is located below the magnet 307.

[0039] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0040] In order to make the rotation of the double-layer circular plate 204 more stable and smooth, a bearing 206 is provided between the bottom circular plate of the double-layer circular plate 204 and the device box 201, which can effectively reduce the friction between the two and improve the operating stability and service life of the rotating component.

[0041] In order to achieve precise transmission of the pitch angle of the spray gun 2078, the linkage mechanism of the adjustment component 207 is preferably configured such that the output end of the electric push rod 2071 is connected to the first rotating shaft 2073, the first rotating shaft 2073 drives the connecting plate 2074, and the connecting plate 2074 acts on the second rotating shaft 2075 connected to the rotating plate 2076. This structure can stably convert the linear motion of the electric push rod 2071 into the swing of the rotating plate 2076 around the third rotating shaft 2077.

[0042] To facilitate the rapid collection and recycling of the separated sand, the drawer 308 at the bottom of the collection box 306 is designed to be pluggable, so that it can be easily pulled out for processing when the sand is full.

[0043] To ensure the stability of the air passage in the sand cleaning mechanism 3, the suction pipe 302 and the exhaust pipe 305 are fixed by the support plate 303, which avoids vibration or displacement of the pipeline during use and ensures the stability and reliability of the dust collection process.

[0044] In order to allow the metal base plate to pass through smoothly while maximizing the isolation of sand and dust inside the outer casing 1, the curtain 4 at the material inlet and outlet is preferably made of a flexible and wear-resistant material, which can form an effective soft seal.

[0045] To achieve automated and integrated control of the entire equipment, the equipment also includes a control panel 6. The control module of the control panel 6 is electrically connected to the motor 202 of the rotating component and the electric push rod 2071 of the adjusting component 207. The operator can input commands through the control panel 6 to precisely control the horizontal rotation angle and the pitch angle of the spray gun 2078.

[0046] Working principle: Before sandblasting the metal floor, the angle to be adjusted for the spray gun 2078 is input into the control panel 6. The control panel 6 then transmits electrical signals to the motor 202 and the electric push rod 2071, causing them to start working. The motor 202 drives the gear 203 connected to the output end to rotate. Since the gear 203 is meshed with the gear ring 205 on the outer side of the upper circular plate of the double-layer circular plate 204, the double-layer circular plate 204 will rotate synchronously with the rotation of the gear 203. The bearing 206 on the outer side of the bottom circular plate reduces the friction between the double-layer circular plate 204 and the device box 201, making its rotation smoother, thereby adjusting the sandblasting direction of the spray gun 2078. Then the electric push rod 2071... 071 begins to extend and drives the first rotating shaft 2073 connected to the output end to begin to descend. The first rotating shaft 2073 drives the connecting plate 2074 connected at both ends to begin to descend and applies a downward pressure to the second rotating shaft 2075, causing the rotating plate 2076 to rotate outward around the third rotating shaft 2077 connected to the bottom of the fixed plate 2072 and gradually tilt. This causes the spray gun 2078 on the rotating plate 2076 to tilt synchronously. The sandblasting angle of the spray gun 2078 is adjusted by the adjusting component 207. The multiple angle adjustment mechanisms 2 set in the housing 1 enable the equipment to quickly adjust the processing angle of the spray gun 2078 when processing large batches and various models of metal base plates, saving time and effort and speeding up the production progress.

[0047] The unprocessed metal base plate is then placed on conveyor belt 5. The metal base plate moves forward with conveyor belt 5 and enters the interior of housing 1, where sandblasting begins and dust collector 301 is activated. Multiple curtains 4 suspended at the entrance and exit of housing 1 isolate the sand material inside housing 1, preventing pollution of the production environment. The processed metal base plate is then transported out of the exit of housing 1 by control panel 6. Dust collector 301 begins operation and generates suction. Suction port 304 sucks in the sand material adhering to the surface of the metal base plate and the cut metal debris, which is then fixed by support plate 303. The suction pipe 302 and the exhaust pipe 305 deliver the waste to the collection box 306. The magnet 307 embedded inside the collection box 306 has magnetic force, which can attract the metal shavings contained in the waste to its surface. The sand will slide down the surface of the magnet 307 into the drawer 308. When the drawer 308 is full of sand, it is taken out and recycled. The sand cleaning mechanism 3 can not only clean the waste attached to the surface of the processed metal base plate, improve the output quality, and reduce the workload of manual cleaning, but also recycle the metal shavings and sand waste, reducing the waste of production raw materials.
