Description

Technical Field

[0001] This utility model relates to the field of PE bottle recycling and processing technology, and in particular to a PE bottle thermal degumming device. Background Technology

[0002] In existing technologies, PE bottles, or polyethylene plastic bottles, are characterized by their fragility, low cost, high transparency, and use of food-grade raw materials. These bottles are convenient to carry, shatterproof, acid and alkali resistant, easy to manufacture, and recyclable. During use, a label is affixed to the outer wall of the bottle, with adhesive applied to the inner walls at both ends. Some adhesive residue remains on the bottle. During the recycling process of PE bottles, after removing the label, it is also necessary to remove any residual adhesive to ensure the quality of the reprocessed products.

[0003] Existing PE bottle surface adhesive removal devices mostly use high-pressure water jet rinsing. Although the cleaning effect is good, in practical applications, when removing adhesive from a large number of PE bottles, high-pressure water jet rinsing requires special equipment such as spraying equipment to soften the adhesive, which makes the overall adhesive removal system larger in size and increases the pressure of subsequent water treatment work.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] A PE bottle thermal desmearing device, such as Figures 1 to 4 As shown, it includes: a constant temperature water bath 1, which is equipped with constant temperature hot water and glue dispensing components, which work together to remove glue by heat; and a transfer component, which has a PE plastic bottle 34 fixed at its bottom and transfers the PE plastic bottle 34 into the glue removal component for heat removal.

[0029] The temperature of the constant temperature hot water inside the constant temperature water bath 1 is set to 70 to 80 degrees Celsius to ensure that the adhesive residue is fully heated. If the wall thickness of some PE plastic bottles 34 is small, the temperature of the constant temperature hot water can be adjusted appropriately, but not lower than 40 degrees Celsius. At the same time, in order to ensure the adhesive removal effect, alcohol or other agents that help dissolve the adhesive residue and will not cause pollution can be sprayed on the adhesive residue.

[0030] The adhesive removal assembly includes a fixed base 17 and a fixed connecting frame 21. The fixed base 17 is fixedly installed on the bottom inner wall of the constant temperature water bath 1. An annular groove is opened at the top of the fixed base 17.

The rotating pin 2 7 is fixedly installed at the end of one of the connecting cross arms 20 and is located above the corresponding connecting support column 19.

[0032] One of the connecting cross arms 20 has a motor base 22 fixedly installed at the top, a drive motor 23 fixedly installed at the top of the motor base 22, and a bevel gear 24 fixedly installed on the output shaft of the drive motor 23.

[0033] The outer wall of the bevel gear 24 is meshed with a bevel gear ring 25. The outer wall of the bevel gear ring 25 is rotatably mounted with a bearing fixing ring 26. The bearing fixing ring 26 is fixedly mounted on the top of multiple connecting cross arms 20. The top of the outer wall of the bevel gear ring 25 is set in a bevel gear shape, and its inner wall is set in a tooth ring shape.

[0034] The inner wall of the bevel ring 25 is meshed with multiple driven gears 27. The bottom end of the driven gear 27 is fixedly installed with a de-adhesive rotating shaft 28. The bottom of the de-adhesive rotating shaft 28 passes through the fixed connecting frame 21 and extends downward. The de-adhesive rotating shaft 28 is rotatably connected to the fixed connecting frame 21.

[0035] A connecting sleeve 29 is fixedly sleeved on the outer wall of the extended end of the adhesive removal shaft 28. Multiple sets of adhesive removal brush bundles 30 are fixedly connected at equal intervals on the outer wall of the connecting sleeve 29. The adhesive removal shaft 28 drives the adhesive removal brush bundles 30 to rotate rapidly to remove the adhesive residue on the surface of the PE plastic bottle 34.

[0036] The main body of the transfer component is a U-shaped mobile frame 8. A lifting cylinder 9 is fixedly installed on the inner wall of the bottom end of the U-shaped mobile frame 8. The telescopic end of the lifting cylinder 9 passes through the bottom frame of the U-shaped mobile frame 8 and extends downward. A lifting connecting plate 12 is fixedly installed on its extended end.

[0037] Multiple connecting rods 13 are fixedly installed at the bottom of the lifting connecting plate 12. A top sealing plate 14 is fixedly installed at the bottom of the connecting rod 13. An inflation tube 15 is fixedly connected to the top of the top sealing plate 14. A three-way connecting valve 16 is fixedly installed at the top of the inflation tube 15.

[0038] Both air ports of the three-way connecting valve 16 are fixedly installed with connecting pipes 11, and air compressors 10 are fixedly installed at the ends of the connecting pipes 11. Both air compressors 10 are fixedly installed on the bottom inner wall of the U-shaped moving frame 8 and are located on both sides of the lifting cylinder 9.

[0039] The two air compressors 10 serve as backups for each other. If one of them fails, the other will start immediately to ensure the continuous operation of the entire unit.

[0040] The bottom of the inflatable tube 15 passes through the top sealing plate 14 and extends downward. An inflatable rubber airbag 31 is fixedly sleeved on the outside of its extended end. The bottom end of the inflatable rubber airbag 31 is provided with a bottom limiting plate 32 that is fixedly connected to the extended end of the inflatable tube 15.

[0041] Multiple diversion tubes 33 are fixedly connected at equal intervals to the outer wall of the inflation tube 15. The bottom end of the diversion tube 33 passes through the top sealing plate 14 and is inserted into the interior of the inflatable rubber airbag 31 to inflate and deflate the inflatable rubber airbag 31.

[0042] Working principle:

[0043] Please refer to Figures 1 to 4 This device is as follows Figure 1 Assemble as shown;

[0044] The U-shaped mobile frame 8 is connected to the overhead suspension rail and moves horizontally on the overhead suspension rail. When clamping the PE plastic bottle 34, the lifting cylinder 9 is first activated, and the lifting cylinder 9 extends so that the bottom of the inflation tube 15 is inserted into the bottle mouth of the PE plastic bottle 34, and the top sealing plate 14 is attached to the top of the bottle mouth. Then, one of the air compressors 10 is activated to inflate the inflation tube 15. Part of the airflow enters the expansion rubber bladder 31 through the diversion conduit 33. The expansion rubber bladder 31 inflates and seals the bottle mouth of the PE plastic bottle 34. Then, the other airflow enters the PE plastic bottle 34 to increase its internal air pressure. Then, the three-way connecting valve 16 is activated to close the inflation tube 15 and turn off the corresponding air compressor 10.

[0045] Subsequently, the U-shaped moving frame 8 moves the PE plastic bottle 34 above the adhesive removal assembly and inserts the PE plastic bottle 34 into the constant temperature water bath 1 along the axis of the fixed connecting frame 21, so that the adhesive residue on the PE plastic bottle 34 is submerged in constant temperature hot water. Then, the drive motor 23 is started, and the drive motor 23 drives the bevel gear 24 to mesh with the bevel gear ring 25, which in turn meshes with the driven gear 27. The driven gear 27 drives the adhesive removal shaft 28 to rotate at high speed. The adhesive removal shaft 28 drives multiple sets of adhesive removal brush bundles 30 to rotate through the connecting sleeve 29, thereby removing the adhesive residue from the PE plastic bottle 34 in constant temperature hot water.

[0046] During the operation of the drive motor 23, the reduction motor 3 is started synchronously. The reduction motor 3 drives the fixed connecting frame 21 to make a cyclical arc motion through the crank-connecting rod structure composed of the drive turntable 4 and the drive connecting rod 6, thereby increasing the working range of the adhesive removal brush bundle 30 and fully carrying out the adhesive removal work.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
