Description

Technical Field

[0001] This utility model relates to a grinding device, specifically a bottle mouth grinding device for plastic bottle processing, belonging to the technical field of plastic bottle processing. Background Technology

[0002] Plastic bottles are a common type of packaging container, mainly made of polymer materials such as polyethylene, polypropylene, and polyester. They are lightweight, sturdy, transparent, and not easily contaminated, and are widely used in the food, cosmetics, and pharmaceutical industries. During the manufacturing process, defects such as burrs and flash may appear at the bottle mouth. These uneven surfaces can affect the fit between the cap and the bottle mouth, leading to poor sealing. A polishing device can smooth the surface of the bottle mouth, removing these defects and allowing the cap to seal the bottle mouth better, preventing leakage of the contents or the entry of outside air, thereby extending the product's shelf life. This method is now widely used.

[0003] Existing bottle neck grinding devices typically involve first fixing the bottle body with clamps or other fasteners, and then grinding the bottle neck with a special grinding wheel. However, existing devices generally require manual disassembly when fixing the bottle body and disassembling after grinding, resulting in low automation. Furthermore, the grinding debris can easily enter the inside of the bottle, requiring further cleaning, which is quite troublesome. Therefore, we provide a bottle neck grinding device for plastic bottle processing to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a bottle neck grinding device for plastic bottle processing, specifically as follows:

[0005] A bottle neck polishing device for processing plastic bottles includes a conveying assembly, a feeding mechanism on one side of the conveying assembly, a support plate on the other side of the conveying assembly, a baffle fixedly mounted on the upper surface of the support plate, a rotating mechanism on the inner wall of the baffle, a lifting mechanism on one side of the support plate, a fixed shell at one end of the lifting mechanism, a power mechanism on the fixed shell, a pressing mechanism at the lower part of the fixed shell, a fixed rod connected to the inner top wall of the fixed shell, a plug connected to the lower part of the fixed rod, a rotating plate rotatably connected to the outer surface of the fixed rod, a polishing wheel connected to the lower surface of the rotating plate, and a blowing assembly on one side of the fixed shell.

[0006] Preferably, the feeding mechanism includes a fixed plate, which is installed on one side of the conveying assembly. A first telescopic rod is installed on the outer surface of the fixed plate, and a push plate is connected to the telescopic end of the first telescopic rod.

[0007] Preferably, the rotating mechanism includes a first motor, which is mounted on the bottom of the support plate, and the output shaft of the first motor passes through the support plate and connects to a rotating disk.

[0008] Preferably, the lifting mechanism includes a second telescopic rod, which is installed on the upper surface of the support plate. The telescopic end of the second telescopic rod is connected to a long plate, and the end of the long plate away from the second telescopic rod is connected to the fixed shell.

[0009] Preferably, the power mechanism includes a second electric motor, which is mounted on the outer surface of the fixed housing. The output end of the second electric motor is connected to a rotating rod, and the outer surface of the rotating rod is rotatably connected to the fixed housing.

[0010] Preferably, a gear is connected to the lower surface of the rotating rod, a gear ring is meshed with the outer surface of the gear, and the inner wall of the gear ring is connected to the rotating plate.

[0011] Preferably, the extrusion mechanism includes an extrusion ring, the upper surface of which is connected to a spring, and the upper end of the spring is connected to a fixed shell.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This bottle neck grinding device for plastic bottle processing incorporates a rotating mechanism and a plug. The plastic bottle is first conveyed to the feeding mechanism by a conveying component. The feeding mechanism guides the bottle into the rotating mechanism, which rotates the bottle to the lower part of the fixed shell for grinding. After grinding, the bottle exits through a circular opening on the support plate. Automatic feeding and discharging reduce manual labor. During grinding, the plug seals the bottle neck to prevent dust from entering the bottle's interior. This solves the problems of existing methods where manual disassembly is generally required after fixing the bottle and after grinding, resulting in low automation and the inconvenience of grinding debris entering the bottle's interior and requiring further cleaning.

[0014] 2. The bottle neck grinding device for processing plastic bottles is equipped with a feeding mechanism and a squeezing mechanism. The extension of the first telescopic rod can drive the push plate to move closer to the squeezing plastic bottle. The upper part of the push plate is equipped with a protruding stop bar, which limits the plastic bottle while pushing it to prevent it from tilting. A spring can give the squeezing ring a downward elastic force, so that the squeezing ring presses the plastic bottle to fix it and prevent the plastic bottle from moving upward when the plug is pulled out.

[0023] Please see Figures 1-6The system includes a conveyor assembly 1, a feeding mechanism 2 on one side of the conveyor assembly 1, a support plate 3 on the other side of the conveyor assembly 1, a baffle 4 fixedly mounted on the upper surface of the support plate 3, a rotating mechanism 5 on the inner wall of the baffle 4, a lifting mechanism 6 on one side of the support plate 3, a fixed housing 7 at one end of the lifting mechanism 6, a power mechanism 8 on the fixed housing 7, a pressing mechanism 9 at the lower part of the fixed housing 7, a fixed rod 10 connected to the inner top wall of the fixed housing 7, a plug 11 connected to the lower part of the fixed rod 10, a rotating plate 12 rotatably connected to the outer surface of the fixed rod 10, a grinding wheel 13 connected to the lower surface of the rotating plate 12, and a blowing assembly 14 on one side of the fixed housing 7. The conveyor assembly 1 is a commonly used conveyor belt, which can convey the plastic bottles to be processed. The shape of the baffle 4 is... The ring is shaped like a notch. The feeding mechanism 2 can push the plastic bottle into the baffle 4 through the notch, and then the rotating mechanism 5 drives the plastic bottle on it to rotate. The support plate 3 has a round opening. After the plastic bottle is polished, it rotates to the round opening and falls downwards for discharge. A collection box or discharge conveyor belt can be set below the round opening to assist discharge. The power mechanism 8 can drive the rotating plate 12 to rotate, so that the polishing wheel 13 polishes the bottle mouth. The plug 11 is made of rubber and can be inserted into the bottle mouth to block it. The blower assembly 14 has a fan inside. After polishing, the blower assembly 14 can blow air on the plug 11 to remove dust. When in use, a dust removal device can be set on the outside to prevent air pollution.

[0024] The feeding mechanism 2 includes a fixed plate 201, which is installed on one side of the conveying assembly 1. A first telescopic rod 202 is installed on the outer surface of the fixed plate 201. The telescopic end of the first telescopic rod 202 is connected to a push plate 203. When the first telescopic rod 202 extends, it can drive the push plate 203 to move closer to the plastic bottle. A protruding stop bar is provided on the upper part of the push plate 203 to limit the plastic bottle while pushing it and prevent it from tilting. The stop bar is higher than the height of the rotating mechanism 5 and will not cause a collision.

[0025] The rotating mechanism 5 includes a first motor 501, which is installed at the bottom of the support plate 3. The output shaft of the first motor 501 passes through the support plate 3 and is connected to a rotating disk 502. The first motor 501 can drive the rotating disk 502 to rotate. The rotating disk 502 has multiple grooves to hold the plastic bottle and drive the plastic bottle to rotate.

[0026] The lifting mechanism 6 includes a second telescopic rod 601, which is installed on the upper surface of the support plate 3. The telescopic end of the second telescopic rod 601 is connected to a long plate 602. The end of the long plate 602 away from the second telescopic rod 601 is connected to the fixed shell 7. When the second telescopic rod 601 extends or retracts, it can drive the fixed shell 7 to move upward or downward.

[0027] The power mechanism 8 includes a second motor 801, which is mounted on the outer surface of the fixed housing 7. The output end of the second motor 801 is connected to a rotating rod 802. The outer surface of the rotating rod 802 is rotatably connected to the fixed housing 7. The output shaft of the second motor 801 is connected to the rotating rod 802 via a belt drive. The second motor 801 can drive the rotating rod 802 to rotate.

[0028] A gear 803 is connected to the lower surface of the rotating rod 802. A gear ring 804 is meshed with the outer surface of the gear 803. The inner wall of the gear ring 804 is connected to the rotating plate 12. The rotating rod 802 can drive the gear ring 804 to rotate through the gear 803, thereby driving the rotating plate 12 to rotate, so that the grinding wheel 13 can rotate.

[0029] The extrusion mechanism 9 includes an extrusion ring 901, and a spring 902 is connected to the upper surface of the extrusion ring 901. The upper end of the spring 902 is connected to the fixed shell 7. The spring 902 can give the extrusion ring 901 a downward elastic force, so that the extrusion ring 901 presses the plastic bottle for fixation.

[0030] The first telescopic rod 202, the first electric motor 501, the second telescopic rod 601, and the second electric motor 801 in this application are common electrical devices in the prior art. This application will not elaborate on their models or internal structures, and they can also be replaced by other power sources.

[0031] In use, the plastic bottle is first conveyed by the conveying assembly 1 to the feeding mechanism 2. The first telescopic rod 202 extends, causing the push plate 203 to move closer to and squeeze the plastic bottle, so that the plastic bottle enters the groove on the rotating disk 502. Then, the first motor 501 drives the rotating disk 502 to rotate, causing the rotating disk 502 to rotate the plastic bottle. When the plastic bottle rotates to the lower part of the fixed shell 7, the second telescopic rod 601 drives the long plate 602 to move downward, thereby driving the fixed shell 7 to move downward, so that the squeezing ring 901 squeezes the bottle body. Under the action of the spring 902, the squeezing ring 901 fixes the bottle body. As the fixed shell 7 continues to move downwards, it drives the plug 11 to be inserted into the bottle mouth, so that the grinding wheel 13 contacts the bottle mouth. The power mechanism 8 drives the grinding wheel 13 to grind the bottle mouth. The plug 11 blocks the inside of the bottle mouth to prevent dust from falling into the bottle. After grinding, the fixed shell 7 moves upwards, first pulling the plug 11 out of the bottle. At this time, the squeezing ring 901 also applies elastic force to the bottle body to prevent the bottle from moving upwards, so that the plug 11 can be pulled out smoothly. Then the squeezing ring 901 moves away from the bottle body. After grinding, the plastic bottle continues to rotate to the round opening on the support plate 3 to facilitate material discharge.
