Description

Technical Field

[0001] This utility model relates to the technical field of melt filtration in plastic film production, and in particular to a melt filtration device for plastic film production. Background Technology

[0002] During the manufacturing process of plastic film, impurities may be present in the raw materials, resulting in impurities in the molded plastic film, which affects product quality and is not environmentally friendly. If plastic film is used to manufacture food packaging bags, it may contaminate food and endanger people's health.

[0003] In existing plastic film production melt filtration devices, such as the plastic melt filtration device disclosed in utility model patent application number 202420969910.X, a filter channel is set in the filter body, and filter components are set on the filter channel. The filter components can filter out impurities in the plastic melt, so that the formed plastic film is free of impurities, improving product quality and environmental friendliness. In addition, by setting up a vertically movable plate, the filter components are distributed vertically on the movable plate. If the filter components become dirty after a period of use, the movable plate can be moved up and down to switch to other filter components for filtration. This eliminates the need for frequent replacement of filter components and improves production efficiency.

[0004] However, during the melt filtration process in plastic film production, impurities can clog the filter screen and reduce material conveying efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a plastic film production melt filtration device that, by setting a driving mechanism and a telescopic mechanism, not only facilitates the replacement of the filter screen during the plastic film production melt filtration process, but also allows for the timely repositioning of the material during filtration to prevent impurities from clogging it, thus ensuring a stable and consistent conveying volume.

[0006] This utility model discloses a melt filtration device for producing plastic film, including a feeding mechanism; it also includes a filtration mechanism, a drive mechanism, a ratchet mechanism, and a telescopic mechanism. The filtration mechanism is installed inside the feeding mechanism, the drive mechanism is installed on the feeding mechanism, the ratchet mechanism is installed inside the feeding mechanism, and the telescopic mechanism is installed on the ratchet mechanism.

[0007] The material conveying mechanism performs filtration, the filtration mechanism performs filtration, the drive mechanism performs filtration, the ratchet mechanism performs unidirectional rotation, and the telescopic mechanism performs telescopic movement. The material is conveyed through the material conveying mechanism and filtered through the filtration mechanism. At the same time, the drive mechanism is opened to drive the filtration mechanism to rotate, and the ratchet mechanism is locked by flipping the drive mechanism. Simultaneously, the telescopic mechanism retracts the equipment. Thus, during the melt filtration process in plastic film production, not only is it convenient to replace the filter screen, but the position of the material can also be changed at any time during filtration to prevent impurities from clogging the filter and ensure a stable and consistent conveying volume.

[0008] Preferably, the material handling mechanism includes a material handling hopper, a sealing door, a feed pipe, and a discharge pipe. The sealing door is rotatably installed at the upper end of the material handling hopper, the feed pipe is installed at the right end of the material handling hopper, and the discharge pipe is installed at the lower end of the material handling hopper. The material enters through the feed pipe, is filtered and processed in the material handling hopper, and is discharged through the discharge pipe. The equipment is inspected and maintained by opening the sealing door.

[0009] Preferably, the filtration mechanism includes a first turntable, a second turntable, and a filter screen. The first turntable is rotatably installed in the feed hopper, the second turntable is rotatably installed in the feed hopper, and the filter screen is clipped onto the first turntable and the second turntable. The second turntable drives the filter screen to rotate, and the material is filtered through the filter screen.

[0010] Preferably, the driving mechanism includes a sleeve block, a fitting block, and a motor. The sleeve block is installed on the left end of the turntable two, the fitting block is rotatably installed on the feed bin, the motor is installed on the left end of the feed bin, and the output end of the motor is connected to the input end of the fitting block. By turning on the motor to drive the fitting block, the fitting block drives the sleeve block to rotate, thereby causing the sleeve block to drive the turntable two to rotate.

[0011] Preferably, the ratchet mechanism includes a ratchet ring, a rotating wheel, and multiple sets of teeth. The ratchet ring is installed inside the feed bin, the rotating wheel is rotatably installed inside the feed bin, and the multiple sets of teeth are rotatably installed on the rotating wheel by a spiral spring. The ratchet ring limits the teeth, causing the rotating wheel to rotate in one direction.

[0012] Preferably, the telescopic mechanism includes a threaded cylinder, a threaded sleeve, and a spring. The threaded cylinder is installed at the left end of the second turntable, and the threaded sleeve is installed at the right end of the turntable. The threaded cylinder and the threaded sleeve are threadedly engaged, and the spring is inserted into the threaded cylinder and the threaded sleeve. The threaded sleeve is fixed by the teeth of the ratchet ring engaging with the turntable, so that when the motor drives the threaded cylinder to reverse, it engages with the threaded sleeve to retract the second turntable, which facilitates the replacement of the filter screen.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the material is conveyed by the feeding mechanism, filtered by the filtering mechanism, and the filtering mechanism is driven to rotate by the opening drive mechanism. The ratchet mechanism is locked by the flipping drive mechanism, and the equipment is retracted in conjunction with the telescopic mechanism. Thus, in the process of filtering the melt in plastic film production, not only can the filter screen be easily replaced, but the position of the material can also be changed at any time during material filtration to prevent impurities from clogging and ensure a stable and consistent conveying volume.
