Description

Technical Field

[0001] This utility model relates to the field of scrap recycling technology, and in particular to a device for recycling scraps from food plastic packaging bags. Background Technology

[0002] A food plastic packaging bag scrap recycling device is a piece of equipment used to recycle scraps generated during the production of food plastic packaging bags. These scraps usually still have some use value. By collecting and processing them through the recycling device, these scraps can be reprocessed into plastic granules or other plastic products, realizing resource reuse, reducing the demand for new plastic raw materials, and thus saving valuable natural resources such as petroleum.

[0003] Chinese Patent CN221161161U discloses a plastic packaging bag scrap recycling device, relating to the field of scrap recycling. The device includes a base plate with a placement groove at its top. A receiving mechanism is housed within the placement groove. A fixing mechanism is located at the top of the base plate, and a cylinder is mounted thereon. A pressing block is fixedly connected to the output end of the cylinder. Side plates are fixedly connected to both sides of the bottom of the base plate. This invention uses a base plate to support and fix the various components at the top. The placement groove holds the receiving mechanism, which stores the recycled scrap. The cylinder moves the pressing block, which automatically compacts the scrap inside the receiving mechanism. This not only saves manpower but also prevents scrap from floating to the outside due to air pressure, thus preventing environmental pollution. The fixing mechanism secures the receiving mechanism, improving its stability during use.

[0004] The aforementioned patents have a low degree of automation during use, requiring frequent manual operation, which reduces work efficiency. They also have difficulty cleaning up residual plastic debris and the processing of scraps is relatively simple, lacking crushing function, which may result in the scraps not being compacted. Based on this, a food plastic packaging bag scrap recycling device is proposed for improvement. Utility Model Content

[0031] like Figure 1 and Figure 5 As shown in the figure, this embodiment provides a recycling device for scraps from food plastic packaging bags, including a workbench 1, a protective shell 2 fixedly connected to the top of the workbench 1, a base plate 3 fixedly connected to the bottom of the workbench 1, a partition 4 fixedly connected to the middle of the workbench 1, a feeding trough 41 opened on one side of the partition 4, and a chip discharge trough 42 opened on the other side of the partition 4. The workbench 1 includes an intermittent mechanism 5 for intermittent movement, a pressing mechanism 6 for pressing materials, a crushing mechanism 7 for crushing, and a cleaning mechanism 8 for cleaning.

[0032] Specifically, the crushing mechanism 7 is used to crush the scrap material so that it can be more tightly pressed and fixed in the future. The intermittent mechanism 5 drives the scrap material to be gradually transported to the bottom of the pressing mechanism 6. The pressing mechanism 6 can press and fix the scrap material of the plastic packaging bag. The cleaning mechanism 8 is used to clean the plastic debris remaining on the inner wall of the pressing tube 57.

[0033] In a further embodiment, a feed pipe 9 is fixedly sleeved on one side of the protective shell 2, and a turntable 56 is rotatably connected to the top of the workbench 1. Several pressing pipes 57 are fixedly sleeved inside the turntable 56, and the bottom ends of the several pressing pipes 57 are in contact with the partition plate 4.

[0034] A cylinder 61 is fixedly installed at the center of the top of the protective shell 2. The output shaft of the cylinder 61 passes through the top of the protective shell 2 and is fixedly connected to a cross plate 62. A pressure block 63 is fixedly connected to the bottom front side of the cross plate 62. The pressure block 63 is slidably connected to the inner wall of the pressure tube 57 on the front side of the turntable 56.

[0035] A push rod 64 is fixedly connected to the bottom right side of the cross plate 62. The bottom end of the push rod 64 is slidably connected to the inner wall of the pressing tube 57 on the right side of the turntable 56. The pressing tube 57 on the right side of the turntable 56 is located above the feeding trough 41.

[0036] A first motor 51 is fixedly installed at the top of the base plate 3. A rotating wheel 52 is fixedly sleeved on the output shaft of the first motor 51. A connecting rod 53 is fixedly connected to the bottom of the rotating wheel 52. An intermittent grooved wheel 54 is movably connected to one end of the connecting rod 53 by a protrusion. A transmission shaft 55 is fixedly sleeved inside the intermittent grooved wheel 54. The top of the transmission shaft 55 is fixedly sleeved inside the turntable 56.

[0037] Specifically, scrap material falls into the pressing tube 57 on the left side of the turntable 56 through the feed pipe 9. Then, the first motor 51 is started, and its output shaft drives the turntable 52 to rotate. When the turntable 52 rotates, the connecting rod 53 will make a circular motion with the turntable 52. The connecting rod 53 causes the intermittent grooved wheel 54 to rotate intermittently. The intermittent grooved wheel 54 drives the turntable 56 to rotate intermittently through the transmission shaft 55. As the turntable 56 rotates intermittently, the pressing tube 57 on the left side will move to the front.

[0038] When the pressing tube 57 moves directly below the pressing block 63, the cylinder 61 is activated, and its telescopic shaft drives the cross plate 62 to move downward. The cross plate 62 drives the pressing block 63 to insert into the inner wall of the pressing tube 57 on the front side of the turntable 56, and presses the scrap material in the front pressing tube 57.

[0039] At the same time, the cross plate 62 will drive the push rod 64 to insert downward into the inner wall of the pressing tube 57 on the right side of the turntable 56. The push rod 64 will push the previously pressed scrap material out of the pressing tube 57 and collect it from the discharge trough 41.

[0040] This design achieves intermittent feeding of scrap materials through intermittent mechanism 5, and the pressing mechanism 6 completes the pressing and unloading of scrap materials. The coordinated work of each component can efficiently perform preliminary processing of scrap materials from food plastic packaging bags for subsequent recycling and reuse.

[0041] In a further embodiment, a third motor 81 is fixedly installed at the top rear side of the cross plate 62. The output shaft of the third motor 81 passes through the interior of the cross plate 62 and is fixedly sleeved with a cleaning brush 82. The cleaning brush 82 is rotatably connected to the inside of the pressing tube 57 on the rear side of the turntable 56. The pressing tube 57 on the rear side of the turntable 56 is located above the chip discharge groove 42.

[0042] Specifically, when the pressing tube 57 on the right side of the turntable 56 moves above the rear chip discharge trough 42 and the cross plate 62 moves downward, the third motor 81 is started. Its output shaft drives the cleaning brush 82 to rotate, cleaning the inside of the pressing tube 57 on the rear side of the turntable 56. The plastic debris, dust and other impurities remaining in the pressing tube 57 are brushed off. The impurities brushed off by the cleaning brush 82 are collected and processed through the chip discharge trough 42, thereby keeping the inside of the pressing tube 57 clean and preparing it for the next receiving of scrap materials.

[0043] In a further embodiment, a second motor 71 is fixedly installed on one side of the top of the protective shell 2. The output shaft of the second motor 71 passes through the top of the protective shell 2 and is fixedly sleeved with a crusher 72. The crusher 72 is rotatably connected to the inner wall of the feed pipe 9.

[0044] Specifically, when the device starts running, the second motor 71 is started, and its output shaft drives the crusher 72 to rotate on the inner wall of the feed pipe 9. When the scrap material enters from the feed pipe 9, it will first pass through the rotating crusher 72 and be crushed into a smaller shape for subsequent compaction.

[0045] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
