Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling, and in particular to a full-automatic label scraping machine for processing labels of drinking water barrels. Background Art

[0002] Drinking water barrels are deformed and damaged due to frequent collisions during use, which is one of the important reasons for recycling water barrels. Over time, these damages make the water barrels no longer suitable for safe storage and transportation of drinking water, so they need to be recycled. The purpose of recycling is to reuse resources. The recycling of drinking water barrels focuses on the barrel body, mainly separating the labels on the barrel body to obtain a barrel body with higher purity for reuse. Currently, the following three methods are mainly used on the market to separate labels and barrel materials:

[0003] 1. Manual scraping: This method involves manually scraping the label off the barrel. Although this method can obtain better material purity and ensure the effective separation of the label and barrel material, it is labor-intensive, inefficient and costly, and is not suitable for large-scale operations.

[0004] 2. Grinding labels: This method removes labels by mechanical grinding. Although it can complete the task more efficiently, a large amount of dust is generated during the grinding process, which poses a threat to workers' health and pollutes the environment. In addition, the grinding process may affect the recycling quality of labels and barrel materials, reducing the quality of recyclable materials.

[0005] 3. Overall crushing followed by separation: This method first crushes the entire bucket including the label, and then attempts to separate the fragments of different materials by physical means. Although this method is fast and efficient, since the initial crushing does not distinguish between material types, the recycled materials contain more impurities, making it difficult to obtain high-purity barrel materials, which makes the recycled materials unable to meet the use standards for higher requirements.

[0006] In order to achieve the effective separation and reuse of the label and the barrel body, and ensure the high purity of the barrel body material, so as to cope with the demand for replacing barrels caused by collision deformation and damage, it is necessary to explore more efficient, environmentally friendly and economical new recycling technologies to solve the drawbacks and pain points of existing methods.

[0075] As a preferred technical solution of this embodiment, the seat body 52 is connected to the third bracket 51 through a linear slider mechanism. Obviously, other common guiding methods can also be adopted.

[0076] The specific operation is as follows:

[0077] 1) First, the water bucket 100 is placed on the pallet 2. Then, the pushing mechanism 3 works. The pushing cylinder 32 pushes the water bucket 100 to the left, so that the water outlet end of the water bucket 100 enters the three-jaw clamping cylinder 42 of the rotating bucket mechanism 4. Then, the jaws of the three-jaw clamping cylinder 42 close to clamp the water outlet end of the water bucket 100. The center line of the jaws of the three-jaw clamping cylinder 42 is slightly higher than the central axis of the water bucket 100 when the water bucket 100 is placed on the pallet 2. The water bucket 100 is lifted upward by a certain distance and separated from the pallet 2 under the clamping action of the three-jaw clamping cylinder 42, and the pushing cylinder 32 resets;

[0078] 2) Then, the vision system 9 cooperates with the first stepping motor 43 to identify the label area on the water bucket 100. That is, the first stepping motor 43 continuously rotates the barrel body. When the vision system 9 identifies the label area, it records. After the identification and recording of all the label areas are completed, the first stepping motor 43 stops rotating. The rotation angle of the first stepping motor 43 corresponds to the size of the label area in this direction;

[0079] 3) Then, the rodless cylinder 61 of the feeding mechanism 6 drives the jaw cylinder 64 close to the rotating bucket mechanism 4. The jaws of the jaw cylinder 64 are pre-opened and enter the water outlet end of the water bucket 100. The pneumatic push rod 63 pre-adjusts the position of the jaw cylinder 64 in the left-right direction so that the jaws of the jaw cylinder 64 correspond to the water outlet end of the water bucket 100 and are staggered from the jaws of the three-jaw clamping cylinder 42. Then, the jaws of the jaw cylinder 64 close to clamp the water bucket 100. After that, the jaws of the three-jaw clamping cylinder 42 are released. Then, the pneumatic push rod 63 moves the water bucket 100 to the right by a certain position to stagger the water bucket 100 from the jaws of the three-jaw clamping cylinder 42. Then, the rodless cylinder 61 acts to drive the water bucket 100 to move forward and upward obliquely until the axis of the water bucket 100 is basically coincident with the axis of the clamping assembly 72. Then, the pneumatic push rod 63 drives the water bucket 100 to move to the left. When the water bucket 100 contacts the end plate 724, it stops;

[0080] 4) Next, the push-pull cylinder 727 operates, driving the annular drive plate 726 to rotate relative to the chassis 722 to clamp the bottom of the water bucket 100 (taking Figure 13 as an example, at this time, the annular drive plate 726 rotates clockwise). During the rotation of the annular drive plate 726, the drive hole 733 has a certain angle with the tangent line, which can push the second pivot 731 to move radially, thereby driving the clamping plate 725 to move radially, that is, the clamping plate 725 moves under the guiding action of the radially aligned first radial hole 730 and second radial hole 732. As shown in Figure 13 , in the state shown, the clamping plate 725 gathers to clamp the bottom of the water bucket 100; then the feeding mechanism 6 resets;

[0081] 5) Next, the pressing mechanism 5 operates, and the driving cylinder 53 drives the seat body 52 and the positioning sleeve 54 to approach the water bucket 100, and the positioning sleeve 54 covers and presses against the water bucket 100;

[0082] 6) Next, the second stepping motor 728 rotates the water bucket 100 for positioning according to the position of the scraping knife mechanism 8. At the same time, the working cylinder 834 of the first scraping knife assembly 83 operates, so that the blade 833 fits against the corresponding label area of the water bucket 100. At the same time, the first driving mechanism 85 drives the blade 833 to reciprocate to scrape the label of the water bucket 100. While the first driving mechanism 85 is working, the second stepping motor 728 rotates step by step at intervals to cooperate to achieve continuous scraping of the label. The second scraping knife assembly 84 works in the same way as the first scraping knife assembly 83. After the label scraping is completed, the scraping knife mechanism 8 resets, and then the pressing mechanism 5 and the push-pull cylinder 727 reset, and the water bucket 100 automatically falls off and is discharged; while the label of the water bucket 100 is being scraped, the subsequent water buckets 100 can enter the rotating barrel mechanism 4 to cooperate with the vision system 9 to realize the identification of the labels of the water buckets 100, so as to improve the work efficiency.

[0083] Since the present invention uses the system 9 to identify the labels of the water buckets 100, when the buckets enter, the buckets can be randomly placed in the circumferential direction, which not only improves the placement efficiency but also provides a basis for realizing subsequent unmanned automatic bucket feeding. Moreover, by using the learning function of the vision system 9, it can adapt to various different label characteristics to facilitate the processing of buckets of different models or different manufacturers;

[0084] The present invention adopts an independent method for label searching and label scraping. While the label scraping operation is being carried out at the label scraping station, a bucket is also placed at the label searching station for label searching and positioning, which greatly shortens the entire working cycle time;

[0085] Since the present invention scrapes off both the surface label and the adhesive attached to the barrel body during scraping, the scraped chips are basically in strip shape rather than powder shape, which not only saves the trouble of first heating and tearing off the label before manual scraping but also does not generate powder-like debris, thus avoiding the harm to workers and the environment;

[0086] In the description of the above embodiments, in order to make the specification concise and clear, some components that have no direct relation to the core innovation points of the present invention and their specific structural details are omitted. These omitted parts all belong to the existing technical categories. For those skilled in the art, based on their professional knowledge and existing technical materials, they can completely realize the design and manufacture of these parts. Therefore, no further detailed description will be given here.

[0087] The embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, without departing from the principle and spirit of the present invention, various changes, modifications, substitutions and variations made to these embodiments still fall within the protection scope of the present invention.
