Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, specifically to a continuous shot blasting device. Background Technology

[0002] Shot blasting, as a core process in metal surface pretreatment, relies on the impact of high-speed shot streams to clean and strengthen the workpiece surface. Traditional intermittent shot blasting equipment often suffers from frequent manual intervention and poor production continuity, making it difficult to meet the demands of modern large-scale industrial production. Therefore, continuous shot blasting equipment is becoming increasingly widely used.

[0003] For example, Chinese invention patent with publication number CN112571297A provides a continuous track shot blasting machine. This shot blasting machine can collect used steel shot through a collection hopper. The steel shot enters the shot blasting hood through the feed pipe, and the shot blasting wheel rotates to perform shot blasting, thereby improving the recycling rate of steel shot and improving practicality.

[0004] However, most existing continuous shot blasting devices only use a belt conveyor to drive the workpiece through the shot blasting machine for shot blasting. In this type of shot blasting, the workpiece spends a relatively short time in the blasting zone, resulting in a decrease in the shot blasting effect and eventually requiring secondary processing, thus reducing work efficiency. Therefore, a continuous shot blasting device is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a continuous shot blasting device to solve the technical problem mentioned in the background art that most existing continuous shot blasting devices only drive the workpiece through the shot blasting machine via a belt conveyor mechanism for shot blasting. However, in this type of shot blasting, the workpiece stays in the shot blasting area for a short time, resulting in a decrease in shot blasting effect and requiring secondary processing, thus reducing work efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a continuous shot blasting device, comprising a shot blasting machine and a conveying mechanism, wherein the conveying mechanism passes through the shot blasting area of ​​the shot blasting machine, and the conveying mechanism includes:

[0007] A support frame extends through the shot blasting area of ​​the shot blasting machine. A chain conveyor is installed on the support frame, and the nodes of the two sets of chains in the chain conveyor are connected by a support rod.

[0008] The mounting brackets are arranged in two sets, one on each side of the support frame. Each set of mounting brackets has a guide ramp on one side, and these guide ramps are arranged in an alternating pattern to form an S-shaped channel. Multiple guide protrusions are spaced apart on one side of each guide ramp.

[0009] A loading and unloading assembly, mounted on the support frame, is used to transport the workpiece to one end of the chain conveyor and remove the shot-blasted workpiece from the other end of the chain conveyor.

[0010] In a preferred embodiment, the loading and unloading assembly includes:

[0011] A first conveyor belt is disposed at one end of the support frame and flush with one end of the chain conveyor section; and

[0012] The second conveyor belt is located at the other end of the support frame and is flush with the other end of the chain conveyor section.

[0013] In a preferred embodiment, the chain conveyor is arranged at an angle, with the first conveyor belt higher than the second conveyor belt.

[0014] In a preferred embodiment, the chain conveyor is connected to the first conveyor belt via a first guide plate and to the second conveyor belt via a second guide plate.

[0015] In a preferred embodiment, a connecting plate and a T-block are respectively provided on both sides of the guide ramp. The connecting plate is connected to the mounting frame by bolts. The mounting frame is provided with a snap-fit ​​rail, and the T-block is snapped into the snap-fit ​​rail.

[0016] In a preferred embodiment, a supporting ridge is provided between the T-block and the guide ramp.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In operation, this device uses a loading and unloading assembly to transport the workpiece to one end of a chain conveyor. The chain conveyor then drives multiple sets of support rods in a circumferential motion to transport the workpiece within the shot blasting machine's processing area. The shot blasting machine then performs shot blasting on the workpiece. During the transport of the workpiece via the chain conveyor and multiple sets of guide ramps, the workpiece moves within an S-shaped channel formed by the staggered arrangement of these ramps. This extends the workpiece's trajectory within the shot blasting machine, increasing processing time. Furthermore, the arrangement of multiple guide protrusions allows the workpiece to roll within the shot blasting machine during movement, reducing processing dead zones and effectively improving processing efficiency.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention. Those skilled in the art can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0026] Example:

[0027] like Figure 1 , 2 As shown, this utility model provides a continuous shot blasting device, including a shot blasting machine 1 and a conveying mechanism. The conveying mechanism passes through the shot blasting area of ​​the shot blasting machine 1. The conveying mechanism includes a support frame 2 that passes through the shot blasting area of ​​the shot blasting machine 1. A chain conveying section 5 is provided on the support frame 2. The nodes of the two sets of chains in the chain conveying section 5 are connected by a support rod 6. A loading and unloading assembly is provided on the support frame 2 for conveying the workpiece to one end of the chain conveying section 5 and removing the shot-blasted workpiece from the other end of the chain conveying section 5. The loading and unloading assembly includes a first conveyor belt 3 provided at one end of the support frame 2 and a second conveyor belt 4 provided at the other end of the support frame 2. The first conveyor belt 3 is flush with one end of the chain conveying section 5, and the second conveyor belt 4 is flush with the other end of the chain conveying section 5.

[0028] This device is suitable for shot blasting of block-shaped parts. During operation, the first conveyor belt 3 transports the workpiece to be shot blasted, allowing it to move onto multiple sets of support rods 6 on the chain conveyor 5. The gap between the support rods 6 should be less than the minimum width of the workpiece to prevent it from falling. During operation, the chain conveyor 5 drives the support rods 6 in a circumferential motion, allowing the workpiece to pass through the processing area of ​​the shot blasting machine 1. The shot blasting machine 1 then performs shot blasting on the workpiece, which is then moved onto the second conveyor belt 4 for transfer.

[0029] like Figure 1 , 2 As shown, in this embodiment, the chain conveyor 5 is arranged at an angle, with the first conveyor belt 3 higher than the second conveyor belt 4. This ensures that the workpiece can move along the inclined plane during shot blasting. The chain conveyor 5 is connected to the first conveyor belt 3 through the first guide plate 7 and to the second conveyor belt 4 through the second guide plate 8, so that the workpiece can be smoothly transferred to the support rod 6 and removed from the support rod 6.

[0030] like Figure 2 , 3 As shown, in this embodiment, mounting frames 9 are provided on both sides of the support frame 2. Guide ramps 11 are arranged on one side of each of the two sets of mounting frames 9. Multiple sets of guide ramps 11 are arranged in an alternating pattern to form an S-shaped channel. Multiple sets of guide protrusions 12 are arranged at intervals on one side of the guide ramps 11. It can be understood that the width of the S-shaped channel is greater than the width of the workpiece. During the conveying process by the chain conveyor 5, the workpiece can move along the S-shaped channel under the action of multiple sets of guide ramps 11, thereby increasing the workpiece's movement time within the shot blasting machine 1 and improving shot blasting efficiency. Furthermore, the arrangement of the guide protrusions 12 allows the workpiece to roll within the shot blasting machine 1, reducing processing dead angles.

[0031] like Figure 2 , 3 As shown, in this embodiment, a connecting plate 13 and a T-block 14 are respectively provided on both sides of the guide ramp 11. The connecting plate 13 is connected to the mounting frame 9 by bolts. The mounting frame 9 is provided with a snap-fit ​​rail 10, and the T-block 14 is snapped into the snap-fit ​​rail 10. By making the guide ramp 11 detachable, it is convenient to replace it after wear or damage. A supporting protrusion 15 is provided between the T-block 14 and the guide ramp 11 to increase the load-bearing capacity of the guide ramp 11 and prevent the guide ramp 11 from deforming after the workpiece comes into contact with it.

[0032] The specific usage and beneficial effects of this utility model are as follows:

[0033] In use, the device transports the workpiece to be processed to one end of the chain conveyor 5 via the loading and unloading assembly. The chain conveyor 5 drives multiple sets of support rods 6 to move in a circumferential direction, thus conveying the workpiece within the processing area of ​​the shot blasting machine 1. The shot blasting machine 1 then performs shot blasting on the workpiece. During the process of conveying the workpiece via the chain conveyor 5 in conjunction with multiple sets of guide ramps 11, the workpiece moves within an S-shaped channel formed by the staggered arrangement of the guide ramps 11. This extends the workpiece's movement trajectory within the shot blasting machine 1, increasing the processing time. Furthermore, the arrangement of multiple sets of guide ribs 12 allows the workpiece to roll within the shot blasting machine 1 during movement, reducing processing dead angles and effectively improving workpiece processing efficiency.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above. Modifications or improvements can be made to this utility model, which is obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of this utility model fall within the scope of protection claimed by this utility model.
