Description

Technical Field

[0001] This utility model relates to the field of PE film production, and in particular to a stretching device for PE film production and processing. Background Technology

[0002] PE film is usually short for polyethylene film, which is made of polyethylene and has the characteristics of moisture resistance and low moisture permeability. PE film usually needs to be produced and processed, which will require the use of stretching equipment.

[0003] Application No. 202223054594.3 discloses a stretching device for PE film production and processing, including a shell and a base. Rollers are provided on both the left and right sides inside the shell. The front end of one roller is fixedly connected to the output end of a rotary motor through the shell, and belts are provided on the outer sides of the two rollers. A first push rod motor is fixedly connected to both the front and rear ends of the shell at the middle position on the right side of the shell. The output end of the first push rod motor is fixedly connected to the left side of the base. A slide rail is provided on the top of the base. A sliding knife is provided in the slide rail and is fixedly connected to a nut pair. The nut pair is provided on the lead screw of a screw motor. The screw motor passes through the rear end of the base and is fixedly connected to the base. Fixed plates are provided at both the front and rear ends of the base. A drive motor is fixedly connected to the top of the fixed plate at the rear end of the base through the fixed plate. The output end of the drive motor is threadedly connected to a rotating shaft, and the other end of the rotating shaft is located in the notch at the top of the front fixed plate. A paper tube is slidably connected to the outer side of the rotating shaft. A second push rod motor is fixedly connected to the middle position on the left side of the top of the shell, and a pressure block is fixedly connected to the output end of the second push rod motor.

[0004] The PE film is conveyed by a belt and extends from inside the housing. A second pusher motor and a pressure block press the PE film onto the belt, causing the extended PE film to wrap around the outside of a paper tube. Then, the first pusher motor pushes the base to the right, while the paper tube winds and stretches the PE film. After the paper tube is wound, the PE film is cut by the movement of a sliding blade. However, the sliding blade is usually set at a fixed height, and the thickness of different paper tubes varies, which can limit its use. Therefore, it is necessary to adjust the size of the sliding blade according to the requirements of the PE film stretching device. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] This utility model provides, for example Figure 1-4The image shows a stretching device for PE film production and processing.

[0039] Example 1: Includes a housing 1, a fixing plate 3, a pressure block 7, and an adjusting mechanism 8. The housing 1 is based on the prior art mentioned in the background. The stretching process of the PE film is as follows: the prepared PE film is put into the inlet, the rotary motor rotates to drive the roller to rotate, the roller rotates to drive the belt outside to rotate, the belt rotates to drive the PE film entering from the inlet to move forward on the belt, the second push rod motor moves to drive the pressure block 7 to move downward, flatten the PE film moving forward on the belt, and then it protrudes from the outlet. The protruding PE film is fixed between the arc-shaped fixing rod and the paper tube 4. The second push rod motor drives the pressure block 7 to move downward to press the PE film. Then the first push rod motor moves to extend and retract, driving the base 2 fixedly connected to it to move to the right, thereby stretching the PE film. Then the drive motor rotates to drive the rotating shaft to rotate, thereby driving the paper tube 4 outside the rotating shaft to rotate, coiling and storing the stretched PE film. This reciprocating motion stretches and stores the PE film. Then the drive motor stops moving, and the lead screw motor rotates to drive the paper tube 4 to rotate. The nut pair on the lead screw slides on the lead screw, thereby driving the slide rail 6 and the fixed column 81 to slide back and forth, so that the blade 5 cuts the PE film rolled to a fixed size. The fixed plate 3 helps to support the paper tube 4, and the pressure block 7 helps to press down on the PE film during stretching. The top of the housing 1 has an outlet, and the side of the housing 1 is provided with a base 2, which helps to support the fixed plate 3 and also helps to drive the paper tube 4 to move to the right to stretch the PE film. The fixed plate 3 is fixedly connected to the top of the base 2. Paper tubes 4 are provided on the side of plate 3, which is beneficial for winding the stretched PE film. At the same time, it is also beneficial for stretching and winding the PE film during rotation. A slide rail 6 is slidably connected on the base 2. A blade 5 is provided above the slide rail 6, which is beneficial for cutting the PE film by winding the paper tube 4 to a certain thickness, and then removing the PE film. The pressure block 7 is located inside the housing 1. The adjustment mechanism 8 is located on the blade 5. The adjustment mechanism 8 is used to adjust the working height of the blade 5 to adapt to different winding thicknesses of the paper tube 4.

[0040] Furthermore, the adjustment mechanism 8 includes a fixed column 81, a support plate 82, and a positioning component.

The fixed column 81 is fixedly connected to the top of the slide rail 6, and the support plate 82 is fixedly connected to the top of the fixed column 81. The support plate 82 is slidably inserted into the inner cavity of the blade body 5. The positioning component is located on the blade body 5 and is used to fix the blade body 5 to the support plate 82.

[0041] Furthermore, the adjustment mechanism 8 also includes a positioning plate 83 and a sliding groove. The positioning plate 83 is convenient to connect with the support plate 82, which facilitates vertical guidance and positioning of the sliding of the blade body 5. The positioning plate 83 is fixedly connected to the top of the inner wall of the blade body 5, and the sliding groove is opened at the top of the support plate 82. The positioning plate 83 and the inner cavity of the sliding groove are slidably interlocked.

[0042] Specifically, the positioning components include a positioning post 84, a square groove, and a drive post 86. The positioning post 84 is located on the side of the support plate 82, the square groove is opened on the side of the cutter body 5, the positioning post 84 is slidably inserted into the inner cavity of the square groove, and the drive post 86 is located inside the square groove and on the side of the positioning post 84.

[0043] More specifically, the positioning assembly also includes a fixed base 85, a fixed frame 87, and a fixing member. The fixed base 85 facilitates the rotation of the drive column 86 within it. The fixed frame 87 is L-shaped, which facilitates the rotation of the drive column 86 on it and also facilitates the horizontal movement of the positioning column 84. The fixed base 85 is slidably inserted into the inner cavity of the square groove, and the drive column 86 is threadedly inserted into the inner cavity of the fixed base 85. The fixed frame 87 is fixedly connected to the side of the positioning column 84. The outer side of the drive column 86 is provided with an annular groove, and the fixed frame 87 is rotatably sleeved inside the annular groove. The fixing member is located on the fixed base 85 and is used to fix the fixed base 85 to the tool body 5.

[0044] Example 2: Based on Example 1, the fixing component includes a connecting ring 88, a connecting post 89, and a locking ring 810. The connecting ring 88 facilitates the support of the fixing seat 85 and makes it easy to install the fixing seat 85. The connecting post 89 facilitates the connection with the connecting ring 88 and makes it easy to position the installation of the connecting ring 88.
