Description

Technical Field

[0001] This application relates to the field of PE dust bag production technology, and in particular to a flattening device for PE dust bag production. Background Technology

[0002] PE dust bags are bags made of polyethylene (PE) material, primarily used to prevent dust, moisture, and other contaminants from damaging or contaminating items. PE dust bags effectively block dust particles. Their tight molecular structure makes it difficult for dust to penetrate the bag, thus providing a relatively clean environment for the packaged items.

[0003] Flattening is a crucial step in the production of PE dust bags. After PE film is produced by blow molding or casting, it may have wrinkles or unevenness. Flattening is mainly to make the film smoother, facilitating subsequent processing steps such as cutting and sealing, and also improving the overall quality and appearance of the dust bag. However, currently, PE dust bag flattening is usually performed in a single pass. While this method reduces costs, it results in poor flattening quality. Therefore, to solve the above problems, this application provides a flattening device for PE dust bag production. Utility Model Content

[0004] To address the issue that single-pass flattening processes result in poor flattening effects, this application provides a flattening device for the production of PE dust bags.

[0005] This application provides a flattening device for producing PE dust bags, comprising a housing, a conveyor belt mounted on the housing, a motor mounted on the rear side of the housing, and a flattening assembly on the housing. The flattening assembly includes a frame, which is fixedly connected to one side of the top of the housing. A screw is rotatably connected to the top of the frame, and a handwheel is fixedly connected to the top of the screw. Multiple columns are symmetrically fixedly connected to the other side of the top of the housing, and pressure plates are movably fitted on the multiple columns. Electric telescopic rods are symmetrically fixedly connected to the top of the housing. A mounting frame is provided inside the frame, and multiple pressure rollers are rotatably connected inside the mounting frame.

[0006] Preferably, a distribution box is installed at the bottom of one side of the housing, and a control panel is installed on the surface of the housing.

[0007] Preferably, the pressure plate is located on the rear side of the frame, and the top ends of the electric telescopic rods on both sides are respectively fixed to the pressure plate.

[0008] Preferably, a limit plate is fixedly connected to the top of each of the multiple columns, and the electric telescopic rod is arranged between the two columns.

[0009] Preferably, the mounting bracket is rotatably connected to the end of the screw, and the pressure plate and multiple pressure rollers are all horizontally arranged on the top of the conveyor belt.

[0010] In summary, this application has the following beneficial technical effects:

[0011] By designing a flattening assembly, during the production of PE dust bags, the produced PE dust bags are placed on a conveyor belt, allowing them to move along the belt. A handwheel drives a screw to adjust the position of the mounting frame, causing the PE dust bags to undergo initial flattening by multiple pressure rollers as they move. The conveyor belt continues to move the PE dust bags until they reach the bottom of the pressure plate. At this point, an electric telescopic rod drives the pressure plate to slide on the column, pressing it down to the top of the PE dust bag. This pressure plate then applies pressure to the PE dust bag, achieving a secondary flattening. Compared to existing technologies, this design allows for a secondary flattening process, improving the flattening effect and facilitating subsequent processing. Attached Figure Description

[0017] The following is combined with Figure 1 - Figure 4 This application will be described in further detail.

[0018] Example:

[0019] A flattening device for PE dust bag production, used for flattening PE dust bags, as described in the reference. Figure 1 - Figure 2The device includes a housing 1, on which a conveyor belt 2 is installed. The conveyor belt 2 facilitates the movement of the PE dust bag, enabling the PE dust bag to be flattened. A power distribution box 3 is installed on the bottom side of the housing 1, which facilitates the connection between electrical equipment. A control panel 4 is installed on the surface of the housing 1, which facilitates the operation of various components of the device. A motor 5 is installed on the rear side of the housing 1, which provides power for the operation of the conveyor belt 2. A flattening component 6 is provided on the housing 1, which facilitates double flattening of the PE dust bag, thereby improving the flattening effect of the PE dust bag.

[0020] During processing, the produced PE dust bags are placed on the conveyor belt 2, and the conveyor belt 2 is driven by the motor 5 to move the PE dust bags on the conveyor belt 2. Then, the PE dust bags are double-flattened by the flattening component 6.

[0021] Reference Figure 3 - Figure 4 The flattening assembly 6 includes a frame 7, which is fixedly connected to one side of the top of the housing 1. A screw 8 is rotatably connected to the top of the frame 7, and a handwheel 9 is fixedly connected to the top of the screw 8. Multiple columns 10 are symmetrically fixedly connected to the other side of the top of the housing 1. Each column 10 has a limit plate 11 fixedly connected to its top, which limits the movement range of the pressure plate 12. The pressure plate 12 is movably fitted on the multiple columns 10, allowing it to slide on the columns 10. The pressure plate 12 is located on the rear side of the frame 7. Electric telescopic rods 13 are symmetrically fixedly connected to the top of the housing 1. The electric telescopic rods 13 are located between the two columns 10, and their tops are respectively fixed to the pressure plate 12. The movement is controlled by electric... The telescopic rod 13 drives the pressure plate 12 to move, and at the same time applies pressure to the pressure plate 12 through the electric telescopic rod 13. The frame 7 is provided with a mounting frame 14, which is rotatably connected to the end of the screw 8. The position of the mounting frame 14 can be easily adjusted by rotating the screw 8. Multiple pressure rollers 15 are rotatably connected inside the mounting frame 14. The pressure plate 12 and multiple pressure rollers 15 are all horizontally set on the top of the conveyor belt 2. In the idle part of this device, all the above-mentioned electrical components, which refer to power components, electrical components and the matching controller and power supply, are connected by wires. For the specific connection method, refer to the working principle below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is the well known technology in this field.

[0022] During the flattening process, the PE dust bag is first placed on the conveyor belt 2, which moves the PE dust bag. At this time, the handwheel 9 is turned according to the height of the placed PE dust bag. The handwheel 9 drives the screw 8 to rotate, thereby adjusting the position of the mounting frame 14. As the PE dust bag moves, it is initially flattened by multiple pressure rollers 15. Subsequently, the conveyor belt 2 continues to move the PE dust bag, so that the PE dust bag moves to the bottom of the pressure plate 12. At this time, the electric telescopic rod 13 drives the pressure plate 12 to slide on the column 10, pressing the pressure plate 12 down to the top of the PE dust bag. The pressure plate 12 applies pressure to the PE dust bag, thereby flattening the PE dust bag a second time.

[0023] This application discloses a flattening device for producing PE dust bags. The working principle is as follows: During processing, the produced PE dust bags are placed on a conveyor belt 2. A motor 5 drives the conveyor belt 2, causing the PE dust bags to move on it. At this time, the handwheel 9 is rotated according to the height of the placed PE dust bags. The handwheel 9 drives the screw 8 to rotate, adjusting the position of the mounting frame 14. As the PE dust bags move, multiple pressure rollers 15 perform initial flattening. Subsequently, the conveyor belt 2 continues to move the PE dust bags until they reach the bottom of the pressure plate 12. At this point, an electric telescopic rod 13 drives the pressure plate 12 to slide on the column 10, pressing the pressure plate 12 down to the top of the PE dust bags. The pressure plate 12 applies pressure to the PE dust bags, thus performing secondary flattening.
