Description

TECHNICAL FIELD

[0001] The application relates to the technical field of plastic processing, and particularly relates to a plastic product processing technology. BACKGROUND

[0002] Polylactic acid is a new type of bio-based and renewable biodegradable material, which is prepared from starch raw materials obtained from renewable plant resources (such as corn, cassava, etc.). The starch raw material is subjected to saccharification to obtain glucose, and then the glucose and certain strains are fermented to prepare high-purity lactic acid, and then a chemical synthesis method is used to synthesize polylactic acid with a certain molecular weight. The polylactic acid has a certain biodegradability, and the molding includes an injection molding scheme, and the vibration frequency and amplitude of an external vibration force are regulated, so that the product quality can be improved and the performance can be optimized. The PLA resin must be dried before use. If the material is exposed to air for more than 1 h, it needs to be dried again, so that the operation of the raw material for many times and the use of a screw extruder inevitably cause the cost to have impurities. The cleaning scheme usually uses the product to be put into a water pool, a water flow line is formed according to water flow floating, and the product is cleaned by being immersed in water, and the bottle body can be well cleaned by moving the outer wall, but the cleaning effect and efficiency of the bottle are low.

Detailed Implementation

[0026] A plastic product processing technology involves placing bottles with their mouths facing the same direction in a linear array and then transporting the bottles using a belt conveyor 61; the bottles are plastic bottles, preferably corn starch-based plastic bottles.

[0027] Among them, a baffle 62 is fixedly connected to the shell of the belt conveyor 61. The baffle 62 is located on the upper right side of the belt conveyor 61 so that the bottles transported from left to right can abut against the baffle 62 after transport, and any two adjacent bottles can contact each other, so that the distance between any two adjacent bottle mouths is equal.

[0028] Further reference Figures 2 to 6 This process is achieved using a plastic processing device, which includes a support frame 11. A telescopic cylinder I 12 is fixedly connected to the front end of the support frame 11. The movable end of the telescopic cylinder I 12 faces rearward and passes through the support frame 11 from front to back. A base frame 13 is fixedly connected to the movable end of the telescopic cylinder I 12. A motor I 14 is fixedly connected to the right end of the base frame 13. The output shaft of the motor I 14 faces left and passes through the support frame 11 from right to left. An annular cylinder 21 is fixedly connected to the output shaft of the motor I 14. The left end of the annular cylinder 21 is open. The annular cylinder 21 has an annular cavity inside. Multiple pipes 22 are fixedly connected to and connected to the outer wall of the annular cylinder 21. The pipes 22 are arranged in an array along the axis of the annular cylinder 21. The telescopic cylinder I 12 is used to drive the pipes 22 to move back and forth. The motor I 14 is used to drive the pipes 22 to rotate around the output shaft of the motor I 14.

[0029] Furthermore, a telescopic cylinder II 31 is fixedly connected to the left end of the base frame 13. The movable end of the telescopic cylinder II 31 faces right and passes through the support frame 11 from left to right. A sealing element 32 is fixedly connected to the movable end of the telescopic cylinder II 31. The sealing element 32 can move to the right to engage with the ring cylinder 21, thus closing the opening of the ring cylinder 21, i.e., closing the cavity. The sealing element 32 can also move to the left to disengage from the ring cylinder 21, thus opening the ring cylinder 21. The sealing element 32 is provided with an exchange hole 33, which is used to connect to a pipeline. This pipeline is connected to an air pump and a water pump through a three-way valve body, allowing the ring cylinder to open. Liquid and gas can be injected into the cylinder 21 so that liquid and gas can be sprayed out of the pipe 22; two exchange holes 33 can also be provided to connect to two pipelines, one of which is connected to a water pump and the other is connected to an air pump. Both pipelines are equipped with valves to close and open the corresponding pipelines; the belt conveyor 61 is located behind the cylinder 21 and the pipe 22; when the seal 32 moves to the right and is located on the right side of a certain pipe 22, the pipe 22 located on the left side of the seal 32 cannot spray water and gas, thus achieving closure, thereby adapting to different numbers of bottles on the belt conveyor 61;

[0030] During operation, tube 22 is moved backward to insert one tube 22 into each bottle. Then, tube 22 is rotated 90° around the output shaft of motor I14, so that the bottle opening on tube 22 faces downward. Water is then injected into the bottle through tube 22 to clean it. Because the bottle opening faces downward, the water flows downward and is discharged, forming a water-flow cleaning solution. After the bottle is emptied of water, gas is injected into the bottle through tube 22 to accelerate the discharge of water and the drying of the bottle. Finally, tube 22 is rotated another 90° to remove the bottle, or the bottle automatically falls 180° to complete the bottle recycling.

[0031] Preferably, the pipe 22 has holes distributed in both the circumferential and axial directions to increase the positions for drainage and venting, achieve three-dimensional spatial discharge, increase the impact points of liquid and gas on the inside of the bottle, and improve the cleaning and water removal effects.

[0032] Preferably, the tubes 22 are arranged in a circumferential array around the ring cylinder 21, with a total of four rows in the circumferential direction. Thus, when the tubes 22 move to the belt conveyor 61 next time, the bottles on the belt conveyor 61 can be removed without adjusting the circumferential position of the tubes 22.

[0033] Preferably, an electric heating element is fixedly connected inside the annular cylinder 21. More preferably, the electric heating element has a meandering structure and is arranged around the inner circumference of the annular cylinder 21, so that any adjacent position of the tube 22 can be heated, and the sprayed water and air are heated.

[0034] Furthermore, a drive disk 45 is provided above the cylinder 21. The axis of the drive disk 45 is vertically set. The drive disk 45 is driven to rotate by a motor II 44. The motor II 44 is located above the drive disk 45. The lower end of the drive disk 45 is spaced from the top of the tube 22 above it. At this time, the inside of the bottle bottom is in contact with the top of the tube 22, increasing the water pressure or air pressure sprayed in the tube 22, so that the bottle can move upward to contact the drive disk 45. The drive disk 45 is used to limit the vertical displacement of the bottle, preventing the bottle from moving upward and detaching from the tube 22. At the same time, the increased pressure further improves the cleaning and drying effect and efficiency of the bottle. When the motor II 44 is started to rotate the drive disk 45, the bottle can rotate around the axis of the tube 22 after contacting the drive disk 45. Thus, the water and air sprayed in the tube 22 can form an impact band on the impact point of the inner wall of the bottle, further improving the cleaning and drying effect and efficiency of the bottle.

[0035] Furthermore, it also includes two straight rods 41 slidably connected to the top of the support frame 11. The upper end of each straight rod 41 is fixedly connected to a limit seat 42, and the lower end of each straight rod 41 is fixedly connected to a base I 43. A roller 46 is rotatably connected to the upper end of the limit seat 42. A base II 51 is fixedly connected to the top of the support frame 11, and a shaft 52 is rotatably connected to the base II 51. An eccentric wheel 53 is fixedly connected to the shaft 52, and a motor III 54 is fixedly connected to the base II 51. The output shaft of the motor III 54 is synchronously driven with the shaft 52 via a pulley and belt assembly. The eccentric wheel 53... Located above roller 46 and in line contact with it, eccentric wheel 53 rolls and rubs against roller 46. A compression spring is sleeved on straight rod 41. The upper and lower ends of the compression spring contact the lower end of limit seat 42 and the upper end of support frame 11, respectively. When motor III 54 is started, the eccentric wheel 53 is rotated, which can repeatedly press down roller 46. The compression spring causes roller 46 to rebound. The purpose is to drive drive disc 45 to repeatedly rise and fall. Then, the bottle, which is raised by water pressure or air pressure, is repeatedly shaken up and down to form an impact surface, which further improves the cleaning and drying effect and efficiency of the bottle.

[0036] Preferably, a container is provided below the ring cylinder 21 and the pipe 22. The bottom surface of the container is provided with a drainage structure, and a sieve plate is fixed inside the container. The top of the sieve plate has an inclined surface to guide the bottle to roll to other positions. The sieve plate can drain water, thereby realizing bottle-water separation.
