Technical Field
[0001] This utility model relates to the field of plastic bottle processing technology, specifically to a spraying mechanism for preventing material jamming. Background Technology
[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. They widely use polyester, polyethylene, and polypropylene as raw materials, adding appropriate organic solvents, and then heating at high temperatures before being molded into plastic containers through blow molding, extrusion blow molding, or injection molding. They are primarily used for single-use plastic packaging containers for liquids or solids such as beverages, food, pickles, honey, dried fruits, edible oils, and agricultural and veterinary drugs. Plastic bottles are characterized by being unbreakable, inexpensive, highly transparent, and made from food-grade raw materials. During the processing of plastic bottles, different types, colors, or properties of plastic raw materials are separated and allocated to meet the production needs of different products. Different plastic raw materials have different physical and chemical properties, such as melting point, hardness, and transparency. By separating the materials, it can be ensured that the raw materials used meet the quality requirements of the product, avoiding defects such as insufficient strength and poor transparency caused by the mixing of raw materials.
[0003] Existing spray-blowing mechanisms for preventing material jamming use air pipes and nozzles installed at both ends of a distribution plate to spray and blow air onto the plastic bottles when distributing them to prevent jamming.
[0004] Existing spray-blowing mechanisms for preventing material jamming have the following problems: when dispensing plastic bottles to prevent material jamming, the spray angle is fixed, which will create spray dead zones and cause blockages, making them inconvenient to use. Therefore, we propose a spray-blowing mechanism to prevent material jamming. Utility Model Content

When distributing plastic bottles, the plastic bottles are first placed on the upper end of the conveyor belt 2. Then, the second motor 10 is operated by controlling the microcontroller 12. The output shaft of the second motor 10 drives the left transmission shaft to rotate. The rotation of the left transmission shaft will drive the conveyor belt 2 to rotate through the right transmission shaft, which will then drive the plastic bottles to move to the left. When it is necessary to distribute plastic bottles, the electric push rod 4 is operated by controlling the microcontroller 12. The telescopic end of the electric push rod 4 pushes the U-shaped block 5 to move to the right, which will then drive the rotating shaft 7 to rotate through the support rod 6.

A worm gear 975 is fixedly connected to the lower end of the output shaft of motor 976. The worm wheel 974 is meshed with the worm gear 975. The input end of motor 976 is electrically connected to the output end of microcontroller 12. Then, it is connected to an external air supply pipe through connecting pipe 91. Then, the front solenoid valve 92 opens and the rear solenoid valve 92 closes. Then, the gas is sprayed out from nozzle 96 through rotary joint 93 and air pipe 95. Then, the plastic bottle is sprayed to prevent the material from passing through the gap below the door panel to prevent material jamming. When the material is not needed, the electric push rod 4 is operated by controlling microcontroller 12. The telescopic end of electric push rod 4 retracts. Electric push rod 4 will reset baffle 8 through U-shaped block 5, support rod 6 and rotating shaft 7. Then, the front solenoid valve 92 closes and the rear solenoid valve 96 closes.

The rotation of rotating column 973 will drive the upper sprocket 971 to rotate. The rotation of sprocket 971 will drive the lower sprocket 971 to rotate via chain 972. The rotation of lower sprocket 971 will drive air pipe 95 to rotate between two bearings 94 and the rotating joint 93, which will then drive nozzle 96 to rotate. Then, when the front rotating column 973 rotates, it will drive the middle part of the counting shaft of angle sensor 978 to rotate.Then, the angle sensor 978 will detect the rotation angle of the rotating column 973 in real time, and transmit the detected data to the microcontroller 12.

[0026] The working principle of the spray mechanism for preventing material jamming provided by this utility model is as follows: When dispensing plastic bottles, the plastic bottles are first placed on the upper end of the conveyor belt 2. Then, the microcontroller 12 controls the operation of the motor 10. The output shaft of the motor 10 drives the left transmission shaft to rotate. The rotation of the left transmission shaft drives the conveyor belt 2 to rotate through the right transmission shaft, thereby moving the plastic bottles to the left. When it is necessary to dispense the plastic bottles, the microcontroller 12 controls the operation of the electric push rod 4. The telescopic end of the electric push rod 4 pushes the U-shaped block 5 to move to the right, which in turn drives the rotating shaft 7 to rotate through the support rod 6. The rotating shaft 7 will drive the baffle 8 to rotate. The right end of the baffle 8 will contact the rear wall of the bracket 1. Under the obstruction of the baffle 8, the plastic bottle will move towards the dispensing trough 11 under the guidance of the baffle 8. Then, it will be connected to the external air supply pipe through the connecting pipe 91. Then, the front solenoid valve 92 will open and the rear solenoid valve 92 will close. Then, the gas will be sprayed out from the nozzle 96 through the rotary joint 93 and the air pipe 95, which will then spray the plastic bottle to prevent the material from passing through the gap under the door panel and prevent the material from jamming. When dispensing is not required, the electric push rod 4 will be operated by controlling the microcontroller 12. The telescopic end of the electric push rod 4 will retract, and the electric push rod 4 will pass through the U-shaped Block 5, support rod 6, and rotating shaft 7 reset baffle 8. Then, the front solenoid valve 92 closes, and the rear solenoid valve 92 opens. When different spray angles are needed, the microcontroller 12 controls the operation of motor 976. The output shaft of motor 976 drives worm 975 to rotate. The rotation of worm 975 drives the meshing worm wheel 974 to rotate. The rotation of worm wheel 974 drives the rotating column 973 to rotate. The rotation of rotating column 973 drives the upper sprocket 971 to rotate. The rotation of sprocket 971 drives the lower sprocket 971 to rotate via chain 972. The rotation of the lower sprocket 971 drives the air... The tube 95 rotates between two bearings 94 and the rotary joint 93, which in turn drives the nozzle 96 to rotate. Then, when the rotating column 973 on the front side rotates, it drives the middle part of the counting shaft of the angle sensor 978 to rotate. The angle sensor 978 will then detect the rotation angle of the rotating column 973 in real time and transmit the detection data to the microcontroller 12. The microcontroller 12 integrates the information and controls the motor 976 to stop operating. Then, it will adjust according to the required angle. By adjusting the angle, the gas kinetic energy is maximized to act on the blockage point, eliminating the spray dead angle generated by the fixed angle nozzle.
[0027] It is worth noting that in the above embodiments, the solenoid valve 92, motor 976, angle sensor 978, and motor 10 are all disclosed. The solenoid valve 92 can be selected from 2W-160-15B, the motor 976 can be selected from YJ61, the angle sensor 978 can be selected from WDD35D4, and the motor 10 can be selected from YS8024. The microcontroller 12 controls the operation of the solenoid valve 92, motor 976, angle sensor 978, and motor 10 using methods commonly used in the prior art.
