Description

Technical Field

[0001] This utility model relates to the field of PE film processing, and more specifically, to a PE film edge cutting device. Background Technology

[0002] During the production of PE film, in order to ensure that the produced PE film meets the specifications, the PE film is cut. After the PE film is cut, there will be residual edge material. In order to improve the reuse of materials, the residual edge material is crushed by an edge material crusher.

[0003] Because PE film possesses a certain degree of flexibility and adhesion, excessive grinding during the pulverization process can lead to overly fine fragments that easily adhere to each other, forming large clumps. This results in uneven material distribution after pulverization. These clumps may clog the discharge port of the pulverizing equipment, affecting the normal flow of material and causing a decline in processing quality. Solving these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a PE film edge cutting device, which aims to solve the problem that PE film fragments tend to stick together during the crushing process of existing PE film edge cutting machines.

[0005] This utility model is implemented as follows:

The storage compartment is slidably connected to the inside of the outer shell, the frame is slidably connected to the outer wall of the storage compartment, the vertical rod is fixedly connected to the bottom of the frame, the first track is located at the bottom inside the outer shell, the curved rod is fixedly connected to the outer wall of the storage compartment, the locking rod is located at the top of the curved rod, the first slide rod is fixedly connected to the bottom of the locking rod, the locking block is fixedly connected to the bottom end of the locking rod, the slide rail is located on the outer wall of the storage compartment, the second slide rod is fixedly connected to the outer wall of the frame, the motor is fixedly connected to the bottom of the inner wall of the outer shell, the eccentric wheel is installed at the output end of the motor, the movable component is installed on the outer wall of the frame, and the connecting plate is installed on the outer wall of the movable component.

[0008] Preferably, the bottom end of the vertical rod extends to the inner bottom of the first track and is slidably connected to the inner wall of the first track; the bottom end of the sliding rod passes through the top end of the curved rod and extends into the inside of the curved rod; and the outer wall of the sliding rod is slidably connected to the inner wall of the curved rod.

[0009] By adopting the above technical solution, the presence of the vertical rod can provide support for the frame. At the same time, the frame can drive the vertical rod to move inside the first track. The locking rod can be moved by sliding, thereby driving the sliding rod to slide inside the locking rod. Meanwhile, the sliding rod can limit the horizontal movement of the locking rod.

[0010] Preferably, the locking block is engaged with the top of the frame, the slide rail is slidably connected to the outer wall of the slide rod, and the two sides of the connecting plate are rotatably connected to the outer wall of the eccentric wheel and the outer wall of the movable part, respectively.

[0011] By adopting the above technical solution, the locking block can be inserted into the interior of the frame, and the horizontal displacement of the storage compartment can be restricted by the locking rod. The slide rail can slide on the outer wall of the slide rod two. The motor drives the eccentric wheel to rotate, and the eccentric wheel can drive the frame to move back and forth through the connecting plate and the moving parts.

[0012] Preferably, the screening assembly includes a bent pipe, a first movable rod, a second movable rod, a screening chamber, a funnel, a cover, a slider, a second track, an extension frame, a diversion frame, and a storage bin.

The outer wall of the bend through which the first movable rod extends and the outer wall of the bend extend are both slidably connected to the inner wall of the bend.

[0014] By adopting the above technical solution, when the frame drives the movable rod one to reciprocate inside the bend, the inside of the bend will be in a state of air compression and negative pressure. At this time, the movable rod two will reciprocate inside the bend under the influence of compressed air and negative pressure.

[0015] Preferably, the outer wall of the movable rod 2 is fixedly connected to the outer wall of the screening chamber, and the outer wall of the screening chamber is slidably connected to the inner wall of the outer shell.

[0016] By adopting the above technical solution, when the movable rod 2 moves back and forth inside the curved tube, it will push the screening chamber to shake inside the outer shell, thereby screening the PE film debris inside the screening chamber.

[0018] By adopting the above technical solution, PE film debris enters the interior of the screening chamber, and if it does not pass through the screen, it will enter the interior of the cutting tank through the extension frame and the diversion frame. The stacking chamber can be disassembled and assembled by sliding.

[0019] The beneficial effects of this utility model are:

[0020] 1. By setting up a screening chamber, when the frame reciprocates under the action of the eccentric wheel, moving parts and connecting plate, it will push the first moving rod to slide inside the bend and pressurize the air inside the bend. The second moving rod will then push the screening chamber to shake under the action of the compressed air inside the bend, thereby screening the PE film and preventing finer PE film fragments from entering the cutting tank. This solves the problem that in the existing PE film edge material machine, PE film fragments are over-crushed, resulting in excessively fine fragments that are easy to stick together.

[0021] 2. By setting up a collection bin and a motor, the shredded PE film will accumulate inside the collection bin, making it convenient for operators to collect. When the motor is running, it will drive the eccentric wheel to rotate. At this time, the frame will cause the collection bin to shake under the action of the moving parts and connecting plates, thereby spreading the PE film shreds accumulated inside the collection bin and improving the collection effect of the collection bin on PE film shreds.
