[0002] A wrapping machine, also known as a stretch film wrapping machine, uses the tension of stretch film to wrap various bulk or whole objects, packaging them into a single unit. It is suitable for rapid transportation or storage, highly adaptable, efficient, low-consumption, reduces labor intensity, and provides dustproof, moisture-proof, and cleanliness protection for the packaged goods, while minimizing surface scratches.

[0003] The switching box is an important component of an automated wrapping machine. In the automated system, it mainly drives valves through pneumatic actuators (such as cylinders) to change the flow direction, on / off state, or distribution state of fluid (gas). Its core function is to achieve precise control and safe switching of the process.

[0004] Due to factors such as the working environment and air quality, waste filaments, waste film, and particulate impurities may enter the equipment from the sealing door and air intake during use. This requires frequent cleaning of the filter screen, which affects the equipment's working efficiency and, in severe cases, can affect the normal use of equipment components, causing equipment failure and shortening the equipment's service life.

When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0022] Furthermore, it should be noted that the directional terms such as left, right, up, and down used in the embodiments of this utility model are only relative concepts or references to the normal use of the product, and should not be considered restrictive. The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] As attached Figure 1 The diagram shows a switching box for a wrapping machine according to this utility model. It includes a base 1 with several bolt holes, which are used to connect the base 1 to the ground, ensuring overall stability and providing some shock absorption. A box body 2 is connected to the base 1, and a removable cover 3 is installed on the top of the box body 2. A closed cavity is formed between the box body 2 and the cover 3, where the flow direction, on / off state, or distribution of gas is changed to switch the working state of the wrapping machine. Air inlet pipes 4, communicating with the cavity, are connected to both sides of the box body 2. An opening is formed at the connection between the box body 2 and the air inlet pipes 4, as shown in the attached diagram. Figure 3 As shown, a first filter 6 is installed at the opening to perform the first stage of filtration on the gas entering the cavity. (See attached image) Figure 2 As shown, a first cylinder 7 is installed on both sides of the housing 2. The output end of the first cylinder 7 is connected to a first sealing plate 8. The first sealing plate 8 moves to open or close the opening under the drive of the first cylinder 7, controlling the airflow between the air intake pipe 4 and the housing 2.

[0024] An exhaust pipe 9 is connected to one side of the housing 2, and the exhaust pipe 9 is connected to a blower for drawing airflow. In this embodiment, the exhaust pipe 9 is located in the middle of the two intake pipes 4. A second filter 10 and a third filter 11 are installed inside the housing 2. The second filter 10 divides the cavity into a part connected to the intake pipe 4 and a part connected to the exhaust pipe 9, filtering the gas entering from the intake pipe 4 again. One end of the third filter 11 is connected to the second filter 10, and the other end is connected to the housing 2, separating the two intake pipes 4 to prevent impurities from entering the other intake pipe 4 when the gas flow direction changes. A fourth filter 19 is also installed inside the housing 2 near the exhaust pipe 9, providing another layer of filtration for the gas, which significantly improves the gas quality and prevents waste fibers, waste membranes, particulate impurities, etc., from entering the blower, weakening the suction, affecting the coating quality, or even causing coating failure, thus reducing the service life of the equipment.

[0025] Several air ports 12 are machined on the end of the cover 3 near the air outlet pipe 9. A protective cover 13 is installed on the outside of the air port 12. A second cylinder 14 is installed inside the protective cover 13. The output end of the second cylinder 14 is connected to a second sealing plate 15. The second sealing plate 15 moves to open or close the air ports 12 under the drive of the second cylinder 14.

[0026] The cover 3 is equipped with a protective plate 16 to cover the first cylinder 7, so as to prevent the movement of the first cylinder 7 from being disturbed and causing injury to personnel, and to improve the protective capability of the device.

[0027] The cover 3 has a handle 17, which makes it easy to lift the cover 3. When cleaning the filter screen, the cover 3 can be opened directly to remove the filter screen from the inside, without repeated disassembly and assembly, which affects the efficiency of equipment use. The inner wall of the housing 2 has a slot 18, through which the second filter screen 10 and the third filter screen 11 are inserted and connected to the housing 2, making it easy to put in and take out the filter screen for cleaning or replacement.

[0028] This utility model discloses a switching box for a wrapping machine, which realizes the guidance and directional delivery control of airflow, solving the problem of unclean filtration of air source impurities and waste fibers in the original switching box, eliminating the need for frequent cleaning of the filter screen, and improving the service life of the equipment.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
