The filter screen can be cleaned by driving a servo motor, and the annular rack plate drives the T-shaped pressing plate to move up and down to press the plastic solution to speed up the filtering speed. In the above document, the material is transported to the filter box by a threaded conveying rod, and the filter box and the conveying box are connected in an integrated manner in the above document, and the conveying box is horizontally arranged as a whole to transport the material. According to the above document, the length of the conveying box as a whole is relatively long, resulting in the threaded conveying rod being unable to transport all the materials in the conveying box, and the horizontal arrangement of the conveying box causes the material to be easily adhered to the inside of the conveying box, and due to the integrated installation method, it is not convenient for the operator to clean the inside of the conveying box, so that the plastic film blowing machine has excessive material adhesion after long-term use, and the material discharge speed in the conveying box is reduced, which not only affects the cleanliness of the plastic film blowing machine, but also reduces the processing efficiency of the plastic film blowing machine. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A plastic film blowing machine includes a main body of the plastic film blowing machine, the plastic film blowing machine includes a base 1, a filter box 2, and a conveying box 3. A fixed box is fixedly installed on the base 1, and a lifting platform 4 is provided in the fixed box. A self-locking wheel is provided at the bottom of the lifting platform 4, and a support rod 5 connected to the conveying box 3 is provided on the lifting platform 4. The conveying box 3 can be moved by the lifting platform 4 and the support rod 5, so that the conveying box 3 can cooperate with the card seat 6;

[0022] A holder 6 is fixedly mounted on the filter box 2, and a feed opening 7 corresponding to the conveying box 3 is provided on the holder 6. By arranging the holder 6 on the filter box 2, the conveying box 3 can be disconnected from the filter box 2, so as to avoid the filter box 2 and the conveying box 3 being integrally connected, which makes it impossible for the operator to clean the inside of the filter box 2. A limiter component for limiting the conveying box 3 is installed on the holder 6;

[0023] The limiting assembly includes a limiting groove 8 provided on the card seat 6, and a fixing plate 9 is fixedly installed on the conveying box 3, and a limiting plate 10 extending into the limiting groove 8 is fixedly installed on the fixing plate 9. The limiting plate 10 is an annular structure, and a locking bolt 11 detachably connected to the card seat 6 is threadedly connected on the fixing plate 9. The limiting plate 10 is driven by the conveying box 3 to extend into the limiting groove 8, and then the fixing plate 9 and the card seat 6 are connected by the locking bolt 11, so that the conveying box 3 and the card seat 6 can be initially limited.

[0024] A positioning groove 12 is symmetrically provided on the base 6, a positioning groove 2 13 is symmetrically provided on the fixing plate 9, a connecting plate 14 is installed on the base 6, and a reinforcing plate 15 and a reinforcing plate 2 16 extending into the positioning groove 12 and the positioning groove 2 13 are fixedly installed on the connecting plate 14, respectively. A fixing bolt detachably connected to the base 6 is threadedly connected on the limiting plate 10, and the reinforcing plate 15 and the reinforcing plate 2 16 extend into the positioning groove 12 and the positioning groove 2 13 respectively, and then the limiting plate 10 and the base 6 are connected by the fixing bolt, so that the conveying box 3 and the base 6 can be fully fixed, and the conveying box 3 is tilted. After installation, the conveying box 3 is in a tilted state, which can not only increase the falling speed of the materials, but also prevent the excessive accumulation of materials.

[0025] It should be noted that the specific models and specifications of the lifting platform 4, the filter box 2, and the conveying box 3 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] When processing the main body of the plastic film blowing machine;

[0028] The self-locking wheel drives the lifting platform 4 to move in the fixed box, so that the lifting platform 4 drives the conveying box 3 to move through the support rod 5 until one end of the conveying box 3 extends to the unloading port 7 in the holder 6;

[0029] When the conveying box 3 moves, the fixing plate 9 and the limiting plate 10 are driven to move, so that the limiting plate 10 can extend into the limiting groove 8, thereby preliminarily connecting the conveying box 3 and the holder 6;

[0030] Install the locking bolt 11 so that the locking bolt 11 connects the fixing plate 9 and the holder 6;

[0031] Press the connecting plate 14 so that the connecting plate 14 drives the reinforcing plate 15 and the reinforcing plate 2 16 to extend into the positioning groove 1 12 and the positioning groove 2 13 respectively, and use the fixing bolt to connect the connecting plate 14 and the card holder 6;

[0032] The material is blown into film through the cooperation of the filter box 2 and the conveying box 3;

[0033] When the main body of the plastic film blowing machine is processed, the connection between the conveying box 3 and the filter box 2 is disconnected, and the operator can clean the inside of the conveying box 3.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
