Description

Technical Field

[0001] The utility model belongs to the technical field of gas cylinder processing, and in particular relates to a bottle body defect grinding device. Background Art

[0002] The most common medical gas cylinders are oxygen cylinders or CNG cylinders used in hospitals, which are mainly used to store compressed natural gas. The quality requirements for this type of gas cylinder are relatively high, so there are requirements and standards for the strength and surface quality of the gas cylinders during the processing. During the processing of the gas cylinder, there are often defects on the surface of the gas cylinder that need to be polished. The existing polishing method uses manual polishing. Since the surface of the bottle body has requirements for the arc degree, the arc degree needs to be guaranteed after polishing. When manual polishing is used, it is easy to cause concave conditions, which does not meet the quality requirements of the bottle body surface. At the same time, when manual polishing is used, in order to ensure the arc degree of the defective position of the bottle body as much as possible or to polish different defective positions, the position of the bottle body needs to be adjusted. Since the bottle body is large, it is not convenient to perform rotary polishing on the bottle body. At the same time, since it is necessary to ensure the stability of the gas cylinder during polishing, the contact area between the gas cylinder and the supporting device below is large. Therefore, it is not convenient for the gripping mechanism to pick up and place the gas cylinder during the process of picking up and placing the gas cylinder. Utility Model Content

[0003] In view of the above-mentioned shortcomings, the purpose of the utility model is to provide a bottle defect grinding device, which solves the problem that when grinding the surface defects of the gas cylinder in the prior art, manual grinding cannot ensure the circular arc of the gas cylinder surface and is inconvenient to take and put.

[0004] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0005] A bottle defect grinding device comprises a frame and a roller group arranged on the frame. The frame is also equipped with a driving mechanism to drive the roller group to rotate and then drive the gas cylinder to rotate. A lifting mechanism is provided below the roller group to drive the gas cylinder to move up and down. The frame is also equipped with a grinding mechanism with adjustable position to grind the defects of the gas cylinder.

[0006] With the above structural design, the lifting mechanism is used to raise the cylinder higher than the roller group, which makes it easier for the grabbing mechanism to take and place the gas cylinder. At the same time, the driving mechanism drives the roller group to rotate, driving the gas cylinder to achieve rotary grinding through the grinding mechanism while rotating. Therefore, the arc degree of the grinding position can be guaranteed, and the grinding efficiency is higher.

[0007] As a further improvement, a positioning mechanism for positioning the gas cylinder is also provided at the end of the frame, and the positioning mechanism includes a telescopic adjustment rod fixedly mounted on the frame, and a positioning rod is transversely provided on the telescopic adjustment rod to limit the bottle mouth.

[0008] By adopting the above structure, the positioning mechanism provided on one side of the gas cylinder can improve the stability of the gas cylinder during the rotational grinding process, and the problem of falling is not likely to occur.

[0009] As a further improvement, the roller group includes two rollers arranged side by side, and both ends of the rollers are rotatably mounted on the frame;

[0010] The driving mechanism comprises a motor arranged inside the frame and a transmission wheel fixedly mounted on the end of the roller, and the output end of the motor is drivingly connected to the transmission wheel through a transmission belt.

[0011] With the above structural design, the motor of the driving mechanism rotates at a constant speed to drive the roller and the gas cylinder to rotate at a constant speed, so that the surface of the gas cylinder can be evenly polished and its arc degree can be ensured, thereby improving the processing quality of the product.

[0012] As a further improvement, a mounting portion is provided on the frame, and both ends of the roller are rotatably mounted on the mounting portion. A tensioning wheel is provided at an adjustable position on the mounting portion to adjust the tension of the transmission belt.

[0013] By adopting the above structural design, the tension of the transmission belt can be adjusted according to the size or mass of the product to be driven to rotate, thereby smoothly driving the rotation processing of gas cylinders of different sizes.

[0014] As a further improvement, a protective shell is provided at the position of the transmission wheel, and protective shells are also provided on both sides of the roller group.

[0015] With the above-mentioned structural design, the protective shell arranged at the transmission wheel position can ensure safety while preventing impurities from entering the drive mechanism and affecting the stability of the transmission. The protective shells arranged on both sides of the roller group are mainly used to prevent the roller from being entangled with other objects during rotation for safety reasons.

[0016] As a further improvement, the lifting mechanism includes a driving cylinder and a supporting wheel mounted on the driving cylinder. The cylinder is fixedly mounted below the frame and passes through the frame to be connected to the supporting wheel arranged between the two rollers.

[0017] With the above structural design, the cylinder arranged below drives the support wheel to contact the gas cylinder and further drives the gas cylinder to move up and down, so that space for grabbing the gas cylinder can be reserved, thereby improving the convenience of taking and placing.

[0018] As a further improvement, the grinding mechanism includes a mounting frame, which is slidably mounted on one side of the frame, and is provided with a vertical adjustment frame, which is provided with a horizontal adjustment component, and the horizontal adjustment component is detachably provided with a grinding piece.

[0019] By adopting the above structural design, the position adjustment in the vertical direction and the horizontal direction can be achieved according to the size of the gas cylinder and the defect position, thereby improving the versatility of the grinding device.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. The utility model can realize rotary grinding of gas cylinders by means of the roller group and the driving mechanism for driving the roller group to rotate, thereby ensuring the uniformity and arc of grinding of surface defects of gas cylinders, improving the quality of gas cylinders, and at the same time, the height position of gas cylinders can be adjusted by the lifting mechanism arranged below, which is convenient for taking and placing gas cylinders;

[0022] 2. The grinding mechanism of the utility model can be pre-adjusted by sliding a mounting frame mounted on the frame, and then adjusted up, down, left and right by a vertical adjustment frame and a horizontal adjustment assembly. Therefore, it can adapt to grinding of gas cylinders of different sizes and defects in different positions, thereby improving the versatility of the grinding device.
