Description

Technical Field

[0001] This utility model relates to a deburring device, specifically a deburring device for the mouth of a plastic bottle, and belongs to the field of bottle mouth polishing technology. Background Technology

[0002] Plastic bottles are mostly produced by blow molding. After the blow molding process cools, plastic burrs will remain at the threads of the bottle neck. These burrs need to be removed by a grinding machine to prevent them from causing the bottle cap to jam or making it difficult to connect tightly to the bottle neck.

[0003] Most existing polishing equipment consists of a polishing machine with a polishing head installed on one side of a conveyor belt. As the conveyor belt transports the bottles, the conveyor belt controls the position of the bottles with the help of photoelectric sensors. After the bottles are clamped, the polishing machine controls the polishing head to polish the bottle mouth. After polishing is completed, the conveyor belt is started again to transport the bottles.

[0004] However, when polishing the bottle neck, although there is a dust suction component on the polishing head, since the bottles are all facing upwards, the polishing debris will enter the inside of the bottle or adhere to the inner wall, requiring subsequent manual deep cleaning. This makes the operation cumbersome and reduces the overall efficiency.

[0005] Therefore, there is an urgent need to develop a device that can clean the inner wall of a bottle and remove residual debris to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to provide a deburring device for the mouth of plastic bottles in order to solve the above-mentioned problems. By installing a support frame, a hollow cylinder and a brush are connected. Driven by the hollow cylinder, the brush is inserted into the bottle for cleaning. Furthermore, by connecting a vacuum hose, air is drawn from the outside of the brush, which is conducive to removing and cleaning debris from inside the bottle.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a deburring device for plastic bottle mouths, comprising a grinding machine, a conveyor belt installed on one side of the grinding machine, an adjustment mechanism installed on the grinding machine, the adjustment mechanism including a mounting plate, multiple grinding components installed on the mounting plate, a clamping component installed at one end of the conveyor belt, and multiple cleaning mechanisms installed at the other end of the conveyor belt, each cleaning mechanism including a support frame, a support frame installed at the other end of the conveyor belt, a hollow cylinder installed at the top center of the support frame, a brush installed on the bottom output shaft of the hollow cylinder, multiple dust suction ports provided on the side wall of the brush, and a clamping mechanism installed on the support frame.

[0008] Preferably, the support frame has an "n" shaped structure, the bottom output shaft of the hollow cylinder is threadedly connected to the inner side of the top of the brush, and a suction nozzle is installed at the bottom of the brush.

[0009] Preferably, the clamping mechanism includes a pressure plate, the pressure plate is slidably connected to the top of the support frame, the pressure plate is connected to the output shaft of the hollow cylinder, the support plates are rotatably connected to both sides of the bottom of the support frame, the tops of the two support plates are rotatably connected to drive rods, and the tops of the two drive rods are rotatably connected to both ends of the pressure plate.

[0010] Preferably, the pressure plate has an "n" shaped structure, and the bottom two sides of the pressure plate are slidably connected to the inside of the side wall of the support frame.

[0011] Preferably, the pressure plate is slidably connected to the bottom output shaft of the hollow cylinder, and a connecting spring is connected between the pressure plate and the bottom output shaft of the hollow cylinder.

[0012] Preferably, rubber plates are installed on opposite sides of the two symmetrical support plates, with the top of the rubber plates extending to the outside of the drive rod.

[0013] Preferably, the adjustment mechanism includes a slider, and a movable groove is provided on one side of the mounting plate. Multiple sliders are slidably connected inside the movable groove. Multiple grinding components are detachably connected to one end of multiple sliders. The grinding components are slidably connected to the mounting plate through the sliders.

[0014] Preferably, the inner side of the movable groove is provided with a scissor-type telescopic frame, one end of the scissor-type telescopic frame is rotatably connected to the inner side of one end of the movable groove, and the other end of the plurality of sliders is rotatably connected to the scissor-type telescopic frame.

[0016] Preferably, one of the sliders is threadedly connected to the end of the guide rod, one end of the guide rod extends to the outside of the mounting plate, and a knob is installed on one end of the guide rod.

[0017] The beneficial effects of this utility model are as follows: the installation of the conveyor belt facilitates integration with the production line. Multiple bottles are sequentially transported to one side of the grinding machine via the conveyor belt. Optical sensors detect and stop the conveyor belt, allowing the clamping components to hold the bottles. The grinding machine controls multiple grinding components to grind the bottle mouths. An adjustment mechanism facilitates position adjustment of the grinding components, allowing for grinding of bottles of different sizes. After grinding, the clamping components reset, and the conveyor belt transports the bottles to the bottom of multiple support frames. Infrared sensors cause the conveyor belt to stop again, and hollow cylinders on the support frames drive brushes to insert into the bottles. The repeated up-and-down sliding of the hollow cylinders cleans the bottle mouths and inner walls. Simultaneously, the connection between the external suction hose and the hollow cylinder allows air to be drawn from the suction ports on the brushes, effectively removing debris and ensuring the bottles remain clean. The downward movement of the hollow cylinders also drives the clamping mechanism to stably hold the bottles. Attached Figure Description

[0025] 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.

[0026] Please see Figures 1-6 As shown, the deburring device for plastic bottle mouths includes a grinding machine 1. A conveyor belt 5 is installed on one side of the grinding machine 1. An adjustment mechanism 4 is installed on the grinding machine 1. The adjustment mechanism 4 includes a mounting plate 401. Multiple grinding components 3 are installed on the mounting plate 401. A clamping component 2 is installed at one end of the conveyor belt 5. Multiple cleaning mechanisms 6 are installed at the other end of the conveyor belt 5. The cleaning mechanism 6 includes a support frame 601. A hollow cylinder 602 is installed at the top center of the support frame 601. A brush 603 is installed on the bottom output shaft of the hollow cylinder 602. Multiple dust suction ports 604 are provided on the side wall of the brush 603. A clamping mechanism 7 is installed on the support frame 601.

[0027] As a technical optimization of this utility model, the support frame 601 has an "n" shaped structure. The bottom output shaft of the hollow cylinder 602 is threadedly connected to the inner side of the top of the brush 603. A suction nozzle 605 is installed at the bottom of the brush 603. The installation of the support frame 601 facilitates the passage of the bottle, supports the hollow cylinder 602 and the brush 603, and makes it easy to disassemble and maintain the brush 603. With the installation of the suction nozzle 605, the bottom of the brush 603 can suck up dust, thereby removing debris from the bottom of the bottle.

[0028] As a technical optimization of this utility model, the clamping mechanism 7 includes a pressure plate 701. The pressure plate 701 is slidably connected to the top of the support frame 601. The pressure plate 701 is connected to the output shaft of the hollow cylinder 602. Support plates 704 are rotatably connected to both sides of the bottom of the support frame 601. Drive rods 702 are rotatably connected to the top of the two support plates 704. The tops of the two drive rods 702 are rotatably connected to both ends of the pressure plate 701. The connection between the pressure plate 701 and the hollow cylinder 602 facilitates the retraction of the hollow cylinder 602. When in position, the pressure plate 701 rises, driving the two drive rods 702 to pull the two support plates 704. The drive rods 702, the support plates 704, and the side wall of the support frame 601 remain horizontal. The hollow cylinder 602 slides down, and the pressure plate 701 drives the two drive rods 702, which in turn drives the support plates 704 to rotate. The connection between the drive rods 702 and the support plates 704 moves outward, achieving a clamping and resisting action on the bottle, ensuring its stability.

[0029] As a technical optimization of this utility model, the pressure plate 701 has an "n" shaped structure. The bottom two sides of the pressure plate 701 are slidably connected to the inside of the side wall of the support frame 601, which facilitates the smooth sliding of the pressure plate 701 on the inner side wall of the support frame 601, plays a guiding role, and at the same time smoothly drives and controls the two drive rods 702.

[0030] As a technical optimization of this utility model, the pressure plate 701 is slidably connected to the bottom output shaft of the hollow cylinder 602, and a connecting spring 705 is connected between the pressure plate 701 and the bottom output shaft of the hollow cylinder 602. By installing the connecting spring 705, the pressure plate 701 can be controlled by driving the connecting spring 705 when the cylinder slides. After the pressure plate 701 slides down to the position, the hollow cylinder 602 will continue to slide down without the elastic force of the connecting spring 705, thus avoiding the pressure plate 701 from obstructing the working stroke of the hollow cylinder 602.

[0031] As a technical optimization of this utility model, rubber plates 703 are respectively installed on opposite sides of the two symmetrical support plates 704. The top of the rubber plate 703 extends to the outside of the drive rod 702. By installing the rubber plate 703, the top of the rubber plate 703 can effectively abut and clamp the side wall of the bottle when the support plate 704 rotates.

[0032] As a technical optimization of this utility model, the adjustment mechanism 4 includes a slider 405. A movable groove 403 is provided on one side of the mounting plate 401. Multiple sliders 405 are slidably connected inside the movable groove 403. Multiple grinding components 3 are detachably connected to one end of multiple sliders 405. The grinding components 3 are slidably connected to the mounting plate 401 through the sliders 405. The opening of the movable groove 403 facilitates the embedded sliding connection of multiple sliders 405, thereby realizing the adjustment of the position of multiple grinding components 3.

[0033] As a technical optimization of this utility model, a scissor-type telescopic frame 406 is provided inside the movable groove 403. One end of the scissor-type telescopic frame 406 is rotatably connected to the inner side of one end of the movable groove 403, and the other end of the plurality of sliders 405 is rotatably connected to the scissor-type telescopic frame 406. By installing the scissor-type telescopic frame 406, it is convenient to control the equidistant adjustment width between the plurality of sliders 405, and the operation is more precise.

[0034] As a technical optimization of this utility model, a guide rod 404 is rotatably connected inside the movable groove 403, and multiple sliders 405 are slidably connected to the outside of the guide rod 404. The installation of the guide rod 404 facilitates the smooth sliding of the sliders 405 inside the movable groove 403, thus playing a guiding role.

[0035] As a technical optimization of this utility model, one of the sliders 405 is threadedly connected to the end of the guide rod 404. One end of the guide rod 404 extends to the outside of the mounting plate 401, and a knob 402 is installed on one end of the guide rod 404. The slider 405 is threadedly connected to one end of the guide rod 404, which facilitates the rotation of the guide rod 404 by rotating the knob 402, thereby driving the slider 405 threadedly connected to it to move. The slider 405 then pulls one end of the scissor-type telescopic frame 406, causing the entire telescopic frame to move, thereby realizing the synchronous movement and adjustment of multiple sliders 405.

[0036] In use, the conveyor belt 5 on the grinding machine 1 is first connected to the production line. Multiple bottles are sequentially transported to one side of the grinding machine 1 via the conveyor belt 5. An optical sensor detects and stops the clamping assembly 2 from holding the bottles. The grinding machine 1 then controls multiple grinding components 3 to grind the bottle mouths. An adjustment mechanism 4 allows for easy adjustment of the position of the grinding components 3, facilitating grinding of bottles of different sizes. After grinding, the clamping assembly 2 resets, and the conveyor belt 5 transports the bottles to the bottom of multiple support frames 601. An infrared sensor then stops the conveyor belt 5 again. Hollow cylinders 602 on the support frames 601 drive brushes 603 to insert into the bottles. As the hollow cylinders 602 slide down, they drive connecting springs 705 to pull the pressure plate 701, causing the pressure plate 701 to drive two drive rods 702 to rotate. This, in turn, causes the rubber plate 703 on one side of the support plate 704 to press against the outside of the bottles. The rubber plate 703 is elastic and provides stable gripping of the bottle without causing wear. After the bottle is securely gripped, the hollow cylinder 602 slides up and down repeatedly, causing the brush 603 to clean the bottle opening and inner wall. Simultaneously, the external suction hose connects to the hollow cylinder 602, allowing the suction port 604 on the brush 603 to draw air, facilitating the removal of debris. With the help of the suction nozzle 605, debris is removed from the bottom inside of the bottle, ensuring its cleanliness. When polishing bottles of different sizes, rotating the knob 402 causes the thread at the end of the guide rod 404 to drive one of the sliders 405. The slider 405 drives the scissor-type telescopic frame 406 to slide, allowing the width of multiple sliders 405 on the scissor-type telescopic frame 406 to be adjusted equidistantly, enabling the polishing assembly 3 to polish bottles of different sizes. Finally, the positions of multiple support frames 601 are also adjusted to achieve the cleaning work for bottles of different sizes.
