Description

Technical Field

[0001] The utility model belongs to the technical field of BOPP film edge material recycling, in particular to a BOPP film edge material recycling device. Background Art

[0002] BOPP film is a very important plastic film. In the packaging industry, it is used to package various commodities, such as food, daily necessities, stationery, etc.

[0003] For example, the Chinese patent with the publication number CN216031848U discloses a plastic crushing device for BOPP film production, which is characterized by comprising a first crushing box, a second crushing box, and a support frame; the first crushing box is provided with a first crushing tool, the first crushing tool is connected to a first motor, the first motor is arranged on both sides of the first crushing box, the first crushing box is symmetrically fixed with a first support seat on both sides, the first support seat is used to support the first motor, the first crushing box is provided with a spray device, the bottom of the first crushing box is fixed with a second crushing box, the second crushing box is provided with a second crushing tool arranged equidistantly, and the second crushing tool is connected to a second motor. Through the setting of the utility model, the plastic is crushed twice, which greatly improves the crushing quality, and because the quality of the plastic film is relatively low, the spray device is provided to make the plastic film easy to sink to the second crushing tool, which is convenient for secondary crushing operation, and can also play a role in cooling and dust reduction of the device.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used, such as: BOPP film needs to be cut into required sizes according to the required size during the production process, and this process will produce some BOPP film scraps. Generally, when processing these BOPP film scraps, the BOPP film scraps will be crushed for reuse and production. When the device crushes and recycles the BOPP film scraps, some larger BOPP film scraps will affect the crushing of small BOPP film scraps, resulting in insufficient crushing of some BOPP film scraps, affecting the overall crushing efficiency. The device cannot distinguish and crush BOPP film scraps of different sizes. In view of this, we propose a BOPP film scrap recycling device. Utility Model Content

[0006] The utility model aims to provide a BOPP film edge material recycling device to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a BOPP film edge material recycling device, comprising:

[0008] A shell, a screen plate is rotatably installed in the shell and near the discharge port, slide grooves are provided on both sides of the inner wall of the shell and away from the discharge port, and limit blocks are fixedly installed on both sides of the screen plate and respectively located in the two slide grooves, and a baffle is fixedly installed on the top of the screen plate and at a position away from the feed port of the shell;

[0009] A vibration assembly, which is located on the housing and is used to drive the screening plate to vibrate;

[0010] A collecting shell, the collecting shell is fixedly installed in the outer shell and is located below the screening plate, a discharging port of the collecting shell is fixedly installed with a discharging hopper 2, one end of the discharging hopper 2 passes through one side of the inner wall of the outer shell and is fixedly installed with a crushing barrel 2, a motor 1 is rotatably installed on the top of the crushing barrel 2, and an output shaft of the motor 1 passes through the top of the crushing barrel 2 and is fixedly installed with a crushing rod 2;

[0011] A discharge hopper 1 is fixedly installed at the discharge port of the shell, a crushing barrel 1 is fixedly installed at one end of the discharge hopper 1, a motor 2 is fixedly installed on the top of the crushing barrel 1, and an output shaft of the motor 2 passes through the top of the crushing barrel 1 and is fixedly installed with a crushing rod 1.

[0012] In the technical scheme, when in use, the staff pulls out the sealing plate from the feed port of the shell, then pours the BOPP film edges of different sizes into the screening plate in the shell through the feed port of the shell, then inserts the sealing plate into the feed port of the shell, then, through the vibration component, the vibration component drives the screening plate to rotate up and down repeatedly, and under the action of the baffle, it can prevent the larger BOPP film edges on the screening plate from leaking out of the screening plate, so that the BOPP film edges of different sizes can be screened;

[0013] Subsequently, start motor one and motor two, so that the output shafts of motor one and motor two respectively drive crushing rod two and crushing rod one to rotate. After screening, smaller BOPP film scraps will fall from the through holes on the screening plate into the collecting shell. Under the action of gravity, the BOPP film scraps in the collecting shell will move toward the direction of the discharge hopper two. Subsequently, the BOPP film scraps will pass through the discharge hopper two into the crushing barrel two for crushing. At this time, some larger BOPP film scraps will stay on the screening plate. Under the action of continuous vibration, the BOPP film scraps will move toward the direction of the discharge hopper one. Subsequently, the BOPP film scraps will pass through the discharge hopper one into the crushing barrel one for crushing, ensuring that BOPP film scraps of different sizes can be crushed separately and BOPP film scraps of similar sizes can be crushed together, which can make the crushing process smoother and avoid large-sized BOPP film scraps hindering the full crushing of small-sized plastics, thereby improving the overall crushing efficiency.

[0017] In the technical solution, the motor is started so that the output shaft of the motor drives the elliptical cylinder to rotate. When the elliptical cylinder rotates, the elliptical cylinder will squeeze one end of the screen plate to move downward, causing the screen plate to rotate downward. Subsequently, the limit blocks on both sides of the screen plate will also move downward, and the two limit blocks will squeeze the corresponding slide plates to slide downward in the corresponding slide grooves. Subsequently, the slide grooves will squeeze the two springs to contract. When the elliptical cylinder rotates to one end that no longer squeezes the screen plate and moves downward, the spring will push the corresponding slide plate to move upward under the action of the spring rebound force, and subsequently the slide plate will drive the limit blocks to move downward. The positioning block moves upward, and the two limit blocks drive the screening plate to rotate upward. When the elliptical cylinder rotates continuously and rapidly, the screening plate will rotate up and down repeatedly. Then, the BOPP film edges of different sizes are poured into the screening plate in the outer shell through the feed port of the outer shell. Then, the sealing plate is inserted into the feed port of the outer shell again. Then, under the action of the continuous up and down rotation of the screening plate and the action of the baffle, the larger BOPP film edges on the screening plate can be prevented from leaking out of the screening plate, and the BOPP film edges of different sizes can be screened.

[0018] In the above technical solution, further, the output shaft of the motor is rotationally connected to one side of the housing.

[0023] In this technical solution, it is ensured that the motor 1 can operate normally; it is ensured that the motor 2 can operate normally.

[0024] In the above technical solution, further, a discharge pipe is fixedly installed at the bottom of the first crushing barrel and the bottom of the second crushing barrel, and a sealing cover is threadedly installed on the discharge pipe.
