Technical Field

[0001] The utility model relates to the technical field of plastic barrel processing, in particular to a plastic barrel inner wall grinding device. Background Art

[0002] Plastic barrels are mostly made of polyethylene, polypropylene and other plastics through blow molding and injection molding. They have good properties for special dangerous goods packaging, and are not easy to break, rust-proof, and light in weight. They are widely used in various fields. During the production and processing of plastic barrels, the inner wall must be polished by a polishing device before they can be put into inventory.

[0003] At present, the inner wall grinding device of a plastic barrel usually places the plastic barrel on a processing table and fastens it with a clamp, and then drives the grinding disc to rotate through a rotating drive source such as a motor, so that the grinding disc evenly grinds the inner wall of the barrel. However, in the production process of plastic barrels, plastic barrels with different inner diameters are usually produced, and when grinding these plastic barrels with different inner diameters, multiple sets of grinding devices are usually required to correspond to the grinding requirements of plastic barrels with different inner diameters, which will increase the production cost.

[0004] Therefore, a plastic barrel inner wall grinding device is proposed to solve the above problems. Utility Model Content

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for grinding the inner wall of a plastic barrel, comprising a frame, on which a supporting mechanism and a grinding mechanism are provided;

[0007] The support mechanism is provided with a rotatable support truncated table, and a three-jaw chuck is fixed on the top surface of the support truncated table;

[0008] The grinding mechanism includes a mounting frame that can move up and down, a pair of mounting columns are slidably installed on the inner side of the mounting frame, the mounting position of the mounting columns is adjustable, a rotating shaft is rotatably arranged in the mounting column through a bearing, a grinding wheel is fixed to the bottom end of the rotating shaft, a driving motor is fixed on the mounting frame, and the output shaft of the driving motor is respectively connected to the pair of rotating shafts through two sets of belt transmission structures.

[0009] Furthermore, a rotating motor is fixed on the frame, and an output shaft of the rotating motor is fixed on the supporting truncated platform.

[0010] Furthermore, a lifting cylinder is fixed on the frame, and an output shaft of the lifting cylinder is fixed on the mounting frame.

[0011] Furthermore, a pair of limiting slide rails are fixed on the frame, and a limiting sliding block slidably connected to the corresponding limiting slide rails is fixed on the mounting frame.

[0012] Furthermore, the belt transmission structure includes a driving wheel fixed on the output shaft of the driving motor, a driven wheel fixed on the rotating shaft, a tensioning wheel rotatably arranged on the mounting frame, and a transmission belt jointly sleeved on the driving wheel, the driven wheel and the tensioning wheel, and the tensioning wheel is slidably mounted on the mounting frame.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The inner wall grinding device of the plastic barrel places the plastic barrel between the claws of the three-claw chuck on the supporting round table. The three-claw chuck clamps and fixes the plastic barrel, which is convenient for the grinding mechanism to perform automatic grinding. During the grinding process, the plastic barrel is not easy to deviate. Then, the output shaft of the rotating motor drives the supporting round table to rotate, and the plastic barrel can be rotated, so that the grinding mechanism can perform all-round grinding on the inner wall of the plastic barrel, so that the inner wall of the plastic barrel is polished more evenly.

The position of the grinding wheel can be changed by changing the mounting position of the mounting column, so that the distance between the two grinding wheels becomes larger or smaller, so as to be suitable for processing plastic barrels of different sizes.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-5 A plastic barrel inner wall grinding device in this embodiment includes a frame 1, on which a supporting mechanism 2 and a grinding mechanism 3 are provided. The plastic barrel is placed on the supporting mechanism 2 for clamping and fixing, and the grinding mechanism 3 can automatically grind the inner wall of the plastic barrel.

[0024] The plastic barrel is fixed by the support mechanism 2, and the support mechanism 2 can also make the plastic barrel rotate, and cooperate with the grinding mechanism 3 to realize all-round grinding of the inner wall, such as Figure 2 As shown, the support mechanism 2 includes a rotating motor 201 fixed on the frame 1 , a supporting truncated table 202 is fixed to the output shaft of the rotating motor 201 , and a three-jaw chuck 203 is fixed to the top surface of the supporting truncated table 202 .

[0025] The plastic barrel is placed between the jaws of the three-jaw chuck 203 on the supporting truncated table 202. The three-jaw chuck 203 clamps and fixes the plastic barrel, which is convenient for the grinding mechanism 3 to perform automatic grinding. The output shaft of the rotating motor 201 can drive the supporting truncated table 202 to rotate, and the plastic barrel can rotate, so that the grinding mechanism 3 can perform all-round grinding on the inner wall of the plastic barrel.

[0026] After the plastic barrel is fixed, the inner wall of the barrel can be polished by the polishing mechanism 3, and the polishing mechanism 3 can be applied to plastic barrels of different sizes, and the use is more flexible, such as Figure 3-4As shown, the grinding mechanism 3 includes a lifting cylinder 301 fixed on the frame 1, the output shaft of the lifting cylinder 301 is fixed with a mounting frame 302, a pair of mounting columns 303 are slidably installed on the inner side of the mounting frame 302, a rotating shaft 304 is rotatably arranged in the mounting column 303 through a bearing, a grinding wheel 305 is fixed to the bottom end of the rotating shaft 304, a driving motor 306 is fixed on the mounting frame 302, and the output shaft of the driving motor 306 is respectively connected to the pair of rotating shafts 304 through two sets of belt transmission structures 307.

[0027] The lifting cylinder 301 is pushed out, so that the grinding wheel 305 is attached to the inner wall of the plastic barrel, and the output shaft of the driving motor 306 rotates. Under the transmission action of the belt transmission structure 307, the rotating shaft 304 can drive the grinding wheel 305 to rotate, and the inner wall of the barrel is polished by the grinding wheel 305.

[0028] A pair of limiting slide rails 308 are fixed on the frame 1, and a limiting slider 309 slidably connected to the corresponding limiting slide rails 308 is fixed on the mounting frame 302. Under the guidance of the limiting slide rails 308 and the limiting slider 309, the movement of the mounting frame 302 is more stable.

[0029] Two sets of belt transmission structures 307 are arranged on the output shaft of the driving motor 306, and do not interfere with each other during transmission. The belt transmission structure 307 includes a driving wheel 3071 fixed on the output shaft of the driving motor 306, a driven wheel 3072 fixed on the rotating shaft 304, a tensioning wheel 3073 rotatably arranged on the mounting frame 302, and a transmission belt 3074 that is commonly sleeved on the driving wheel 3071, the driven wheel 3072 and the tensioning wheel 3073. The tensioning wheel 3073 is slidably installed on the mounting frame 302. When the position of the rotating shaft 304 changes, the installation position of the tensioning wheel 3073 also changes accordingly. The installation principle of the tensioning wheel 3073 is the same as that of the mounting column 303.

[0030] In addition, the installation position of the mounting column 303 is adjustable. The mounting column 303 is installed on the mounting frame 302 by bolts and nuts, and a long hole is opened at the corresponding position of the mounting frame 302. The bolt is passed through the long hole of the mounting frame 302 and through the mounting column 303, and then the nut is screwed in. The mounting column 303 can be pressed onto the mounting frame 302 by the nut, and the installation spacing of a pair of grinding wheels 305 can be flexibly adjusted according to the size of the plastic barrel.

[0031] By adopting the above-mentioned plastic barrel inner wall grinding device, it can be applied to plastic barrels with different inner diameters, and the use is more flexible. The specific grinding method is as follows:

[0032] After adjusting the distance between the two grinding wheels 305 according to the inner diameter of the plastic barrel to be processed, the plastic barrel to be processed can be placed on the supporting truncated table 202 and fastened by the three-jaw chuck 203. The lifting cylinder 301 is pushed out to make the grinding wheel 305 stick to the inner wall of the plastic barrel, and the output shaft of the driving motor 306 rotates. Under the transmission action of the belt transmission structure 307, the rotating shaft 304 can drive the grinding wheel 305 to rotate, and then the supporting truncated table 202 is driven to rotate through the output shaft of the rotating motor 201, so that the plastic barrel can be rotated, and the grinding wheel 305 can automatically grind the inner wall of the plastic barrel.
