Description

Technical Field

[0001] This utility model belongs to the technical field of shot blasting machine related equipment, specifically relating to a new type of conveyor roller frame for shot blasting machines. Background Technology

[0002] A shot blasting machine is a mechanical device used for surface treatment; it can remove impurities such as oxide scale, rust, oil stains, and old paint layers from the surface of metal workpieces. During shot blasting, the workpiece needs to be fed into the machine via conveyor rollers. In actual work, we have encountered some problems. After prolonged operation, the pressure from the workpiece on the conveyor rollers can cause significant stress on the connected bearings. Traditional bearing installation methods involve fixing the bearings and connecting parts to the top of the I-beam, meaning the entire weight and pressure are borne by the top of the I-beam, which can easily lead to deformation over time. Furthermore, when workpieces are conveyed on the conveyor rollers, slight vibrations or the special characteristics of irregularly shaped workpieces can cause them to move out of the optimal shot blasting position, thus affecting the shot blasting effect. To address these issues, a new type of conveyor roller frame for shot blasting machines with more comprehensive functions has been proposed. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please refer to the accompanying diagrams in all instruction manuals: A novel conveyor roller frame for a shot peening machine includes a base 1, a power mechanism mounted on the base 1, a conveyor roller mechanism connected to the power mechanism, and a workpiece auxiliary positioning mechanism on the base 1 corresponding to the conveyor roller mechanism. The power mechanism includes a motor 2 mounted on the base 1, and a reducer 3 fixedly mounted on the output end of the motor 2. The conveyor roller mechanism includes an I-beam 4 symmetrically fixedly mounted on the base 1, a plurality of conveyor rollers 5 rotatably connected to the I-beam 4, a sprocket 6 fixedly mounted on one end of each conveyor roller 5, a chain 7 connecting the sprockets 6, and the output end of the reducer 3 fixedly connected to one of the sprockets 6. A fixing block 8 is fixedly mounted on the I-beam 4 corresponding to the conveyor roller 5, a bearing 9 is fixedly mounted on the fixing block 8, the inner ring of the bearing 9 is fixedly connected to the conveyor roller 5, and a load-bearing block 10 is fixedly mounted on the I-beam 4 below the fixing block 8. As described above, the workpiece to be processed is placed on the conveyor roller mechanism, which is then driven by the power mechanism for transmission. The position of the workpiece is adjusted before or during transmission to achieve the best shot blasting effect. The transmission through the mechanical structure of sprocket 6 and chain 7 can reduce problems such as slippage in belt transmission and improve overall work efficiency. The core benefit of setting up reducer 3 is to achieve speed reduction and torque increase, while optimizing the operating efficiency and stability of motor 2 under specific working conditions. Because traditional conveyor rollers have fixed blocks 8 and bearings 9 installed above the I-beam 4, the bearing surface of the I-beam 4 is relatively small. After long-term use, the upper part of the I-beam 4 will show obvious deformation, causing the overall workpiece to fluctuate significantly during conveying. By placing the fixed blocks 8 and bearings 9 inside the I-beam 4 and supporting the load with the load-bearing blocks 10, the bearing area of ​​the I-beam 4 can be increased, thereby significantly increasing the time that the overall conveying stability is maintained.

[0022] As a technical optimization of this utility model, the auxiliary positioning mechanism for the processing part includes a slide groove 11 set on the base 1, a screw 12 rotatably connected in the slide groove 11, a driving device installed in the base 1 corresponding to the screw 12, a base plate 13 slidably connected in the slide groove 11, the base plate 13 being screwed to the screw 12, a dual-axis motor 14 fixedly installed on the base plate 13, a screw 15 fixedly installed on the output end of the dual-axis motor 14, a connecting rod 16 threadedly connected to the screw 15, an auxiliary plate 17 fixedly installed on the connecting rod 16, and a V-shaped opening 18 provided on one side of the auxiliary plate 17; As can be seen from the above description, different workpieces may require different positions when entering the shot blasting machine. For relatively symmetrical workpieces, the two auxiliary plates 17 are moved symmetrically, and the dual-axis motor 14 drives the rotation of the screw 15 to gradually straighten the workpiece to a more centered position. If the workpiece is not of normal appearance, it may be necessary to process it to one side. In this case, the screw 12 needs to be rotated to drive the base plate 13 to move laterally, and the two auxiliary plates 17 above the conveyor roller 5 are used to clamp and bring the workpiece closer to one side.

[0023] As a technical optimization of this utility model, a number of rollers 19 are uniformly rotatably connected to the auxiliary plate 17. As can be seen from the above description, the roller 19 can reduce the friction between itself and the workpiece, making the workpiece more stable when transported on the conveyor roller 17.

[0024] As a technical optimization of this utility model, a sliding rod 20 is fixedly installed on the base plate 13, and the sliding rod 20 is slidably connected to the connecting rod 16. As can be seen from the above description, the slide bar 20 can improve the stability of the movement of the connecting rod 16 and the auxiliary plate 17.

[0025] As a technical optimization of this utility model, the fixing block 8 is provided with a plurality of threaded positioning holes 21 evenly, and the load-bearing block 10 is in the shape of a mountain. As can be seen from the above description, the threaded positioning hole 21 can fully fix the fixing block 8 on the I-beam 4, distribute the force, and increase the overall rigidity.

[0026] As a technical optimization of this utility model, the base plate 13 is provided with a pulley on the side, and the pulley is in contact with the slide groove 11; As can be seen from the above description, the pulley can reduce the friction during sliding, making the sliding of the base plate 13 smoother.

[0027] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
