Description

Technical Field

[0001] This utility model relates to the technical field of plastic bottle processing equipment, and more specifically, to an environmentally friendly rotating cleaning device for finished plastic bottle production. Background Technology

[0002] After the plastic bottle preform is blown through the mold of the blown film machine, the finished plastic bottle is obtained. In the subsequent process, the plastic bottle needs to be transported to the cleaning workshop by the conveyor belt and the mold head. In the cleaning workshop, hydraulic telescopic cylinders are used to drive high-pressure nozzles to vertically push into the inside of each plastic bottle on the conveyor belt to rinse the inside of the plastic bottle.

[0003] The existing cleaning operation has the following problems: First, the plastic bottle is fixed in place throughout the cleaning process, and the high-pressure water is sprayed vertically. In reality, it can only spray the bottom area of ​​the bottle, making it difficult to thoroughly clean the impurities on all sides of the plastic bottle. The cleaning effect is not good enough. Second, the current cleaning equipment is not designed with a corresponding wastewater tank. The dirty water after cleaning falls directly down the equipment frame onto the factory ground and air dries naturally, which is not environmentally friendly and does not conform to the concept of green processing and production. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly rotary cleaning device for finished plastic bottle production. This device can perform rotary cleaning on finished plastic bottles, ensuring thorough cleaning without dead angles and achieving good cleaning results. At the same time, it can collect cleaning wastewater in a unified manner, protecting the factory production environment and realizing the concept of environmentally friendly processing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An environmentally friendly rotating cleaning device for finished plastic bottle production includes several equally spaced supports. Two parallel mounting slots are mounted on each support, and a conveyor belt slides within the slots. Several arc-shaped brackets are spaced apart on the surface of the conveyor belt, each containing a plastic bottle. A cabinet is located outside each mounting slot, and a control panel is located on the left side of the cabinet. A U-shaped pipe is connected and fixed to the outer side of the cabinet via support rods. A high-pressure water pipe is connected to the outer end of the U-shaped pipe. A waste collection bin is located below the U-shaped pipe, and a pressure sensor is installed at the lower end of the waste collection bin.

[0007] As a further optimization of this solution, the upper surface of the cabinet is provided with two parallel rotating bearing seats, and a rotating shaft is connected between the two parallel rotating bearing seats via a rotating part. The outer end of the rotating shaft is connected to the output shaft of the rotating motor through the rotating part of the rotating bearing seat. A connecting rod is fixed on the shaft body, and a mechanical claw is connected to the outer end of the connecting rod. The mechanical claw is composed of symmetrical left and right arc-shaped retaining rings, and the mechanical claw is driven to open or close by a drive motor at the outer end of the connecting rod.

[0008] As a further optimization of this solution, a rotating cleaning nozzle is fitted inside the U-shaped pipe, and an inner lining rotating cylinder is fixedly connected below the rotating cleaning nozzle. The inner lining rotating cylinder is fitted inside the hollow area of ​​the cylindrical outer shell, and the lower end of the outer shell is screwed into and fixed to the inner end of the U-shaped pipe by external threads. A propeller bracket is fixed inside the inner lining rotating cylinder.

[0009] As a further optimization of this solution, sealing rings are filled between the outer surfaces of the upper and lower ends of the inner lining cylinder and the outer shell.

[0010] As a further optimization of this solution, the cabinet is connected to an external factory power supply, and the control panel is connected to the rotating motor, drive motor, pressure sensor, and high-pressure water tank electrical control valve via wiring.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This utility model, through the design of mechanical claws, connecting rods, and rotating shafts, can invert and grab plastic bottles from the conveyor belt for cleaning operations. Combined with the designed waste collection bin structure, it facilitates the discharge of dirty water while enabling unified collection and treatment of dirty water, reducing pollution on the factory ground.

[0013] This invention features a rotating cleaning nozzle structure. High-pressure water can be used to flush the propeller support inside the inner liner of the rotating cylinder, causing the rotating cleaning nozzle to rotate and spray cleaning water repeatedly in all directions. This effectively cleans impurities on all sides of the plastic bottle, resulting in a good cleaning effect. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] To address the issues of the current cleaning process where the plastic bottles are fixed in place and the high-pressure water is sprayed vertically, which only reaches the bottom of the bottle and makes it difficult to thoroughly clean impurities from all sides of the bottle, resulting in insufficient cleaning effect; secondly, the current cleaning equipment does not have a corresponding wastewater tank, and the dirty water after cleaning falls directly down the equipment frame onto the factory floor to air dry, which is not environmentally friendly and does not conform to the concept of green processing and production.

[0021] like Figure 1 As shown, this application includes several brackets 1 arranged at equal intervals. Two parallel mounting slots 2 are mounted on the brackets 1, and a conveyor belt 3 is slidably mounted inside the slots between the mounting slots 2. Several arc-shaped brackets 4 are spaced apart on the surface of the conveyor belt 3, and a plastic bottle 5 is embedded inside each arc-shaped bracket 4. A cabinet 6 is provided outside the mounting slots 2. A control panel 7 is provided on the left side of the cabinet 6. A U-shaped pipe 9 is connected and fixed to the outer side of the cabinet 6 through a bracket rod 8. A high-pressure water pipe 10 is connected to the outer end of the U-shaped pipe 9. A waste collection bin 11 is provided in the area below the U-shaped pipe 9. A pressure sensor 12 is provided at the lower end of the waste collection bin 11.

[0022] like Figure 2 As shown, the upper surface of the cabinet 6 is provided with two parallel rotating bearing seats, and a rotating shaft 13 is connected between the two parallel rotating bearing seats. The outer end of the rotating shaft 13 is connected to the output shaft of the rotating motor 14 through the rotating part of the rotating bearing seat. A connecting rod 15 is fixed on the shaft body of the rotating shaft 13. A mechanical claw 17 is connected to the outer end of the connecting rod 15. The mechanical claw 17 is composed of symmetrical left and right arc-shaped retaining rings, and the mechanical claw 17 is driven to open or close by the drive motor 16 at the outer end of the connecting rod 15.

[0023] like Figure 3 and Figure 4As shown, a rotating cleaning nozzle 18 is fitted inside the U-shaped pipe 9. A liner cylinder 19 is fixedly connected below the rotating cleaning nozzle 18. The liner cylinder 19 is fitted inside the hollow area of ​​the cylindrical outer shell 22. The lower end of the outer shell 22 is screwed into and fixed to the inner end of the U-shaped pipe 9 by external threads. A propeller bracket 20 is fixed inside the liner cylinder 19. Sealing rings 21 are filled between the outer surfaces of the upper and lower ends of the liner cylinder 19 and the outer shell 22.

[0024] In actual operation, the cabinet 6 is connected to an external factory power supply. The control panel 7 is connected to the rotary motor 14, drive motor 16, pressure sensor 12, and high-pressure water tank electric valve via wiring. The electric valve is connected to the high-pressure water pipe 10. When the first plastic bottle 5 on the conveyor belt 3 is transported to the inside of the cabinet, the conveyor belt 3 stops working. Initially, the mechanical gripper 17 is in the open state. The rotary motor 14 is started through the control panel 7 to drive the rotating shaft 13 to move, causing the mechanical gripper 17 to be positioned on both sides of the plastic bottle 5 inside. Then, the drive motor 16 is controlled to drive the mechanical gripper 17 to close and grab the plastic bottle 5. The connecting rod 15 continues to drive the plastic bottle 5 to flip in the opposite direction. Figure 1 At the position of the plastic bottle 5 shown, the bottle mouth of the plastic bottle 5 is aligned and inserted into the rotating cleaning nozzle 18. The electric control valve is opened, and high-pressure water is introduced into the high-pressure water pipe 10. The high-pressure water washes the propeller support 20 inside the inner liner rotating cylinder 19, causing the rotating cleaning nozzle 18 to rotate and spray cleaning water repeatedly in all directions. This can thoroughly clean the impurities on all sides inside the plastic bottle 5. The dirty water during the cleaning process will flow down along the outer perimeter of the bottle mouth of the plastic bottle 5 under the action of gravity and enter the waste collection bucket 11 below.

[0025] The weight of the dirty water inside the waste collection bin 11 can be monitored in real time by the pressure sensor 12. When the weight exceeds the set threshold, the control panel 7 will sound an alarm hummingbird to remind staff to clean up the dirty water inside the waste collection bin 11 and maintain the cleanliness of the site.
