[0021] See also Figure 1-4 , the embodiments of the utility model are further described;

[0022] An automatic cutting mechanism for film bag raw materials, comprising: a mounting plate 1, a loading assembly, a bidirectional cutting assembly, a bidirectional transmission assembly and a cleaning assembly, wherein the mounting plate 1 and the bidirectional transmission assembly are both fixed on a wall, the bidirectional transmission assembly is located below the mounting plate 1, the bidirectional cutting assembly is transmission-connected to the bidirectional transmission assembly, the loading assembly is fixed on the mounting plate 1, the cleaning assembly is mounted on the mounting plate 1, and the cleaning end of the cleaning assembly is located above the bidirectional cutting assembly, and the cleaning assembly is used to clean debris on the bidirectional cutting assembly;

[0023] Specifically, in the initial state, the bidirectional cutting assembly is located at one end of the bidirectional transmission assembly, the roll film is loaded into the loading assembly, and then one end of the roll film is pulled out of the loading assembly and fixed on the winding assembly outside the mechanism, at this time, the bidirectional cutting assembly is aligned with the film, and the winding assembly is started to wind the film, and when the film is wound to a specified length, the winding assembly is closed, and then the bidirectional transmission assembly is started forward to drive the bidirectional cutting assembly to move, and the bidirectional cutting assembly can cut multiple films in sequence;

[0024] After the first round of film cutting is completed, the bidirectional cutting assembly is transferred to the other end of the bidirectional transmission assembly. At this time, the bidirectional transmission assembly is turned off, and the cleaning assembly is started to clean the debris on the bidirectional cutting assembly. After 5 seconds, the cleaning assembly is stopped to complete the cleaning operation of the bidirectional cutting assembly.

[0025] Then, one end of the roll film is pulled out from the loading assembly again and fixed on the winding assembly outside the mechanism, and the winding assembly is started to wind the film. When the film is wound to a specified length, the winding assembly is closed, and then the bidirectional transmission assembly is started in the reverse direction to drive the bidirectional cutting assembly to move, and the bidirectional cutting assembly can cut multiple films in sequence;

[0026] When the second round of film cutting is completed, the bidirectional cutting assembly is transferred to the initial end of the bidirectional transmission assembly. At this time, the bidirectional transmission assembly is closed and the cleaning assembly is started to clean the debris on the bidirectional cutting assembly. After 5 seconds, the cleaning assembly is stopped and the bidirectional cutting assembly cleaning operation is completed. This cycle is repeated.

[0027] Compared with the existing technology, the advantages of this solution are:

[0028] 1. With the use of the bidirectional cutting component and the bidirectional transmission component, the mechanism can realize bidirectional cutting. The bidirectional cutting component does not need to be reset after cutting the film, which can reduce the loss of kinetic energy and save time. It is more practical than the existing one-way cutting.

[0029] 2. After the bidirectional cutting component has finished cutting a round of film, the cleaning component can clean the bidirectional cutting component and remove the debris on the bidirectional cutting component, which is conducive to the bidirectional cutting component to continue to maintain a good cutting state to avoid a decrease in cutting accuracy.

[0030] The loading assembly includes a semicircular tube 2 and a partition 3. The semicircular tube 2 is fixed on the mounting plate 1 and is used to load the roll film. A plurality of discharge holes are opened on one side of the bottom of the semicircular tube 2. The partition 3 is provided with a plurality of pieces and is fixed in the semicircular tube 2 to limit the roll film in the semicircular tube 2. The partition 3 and the discharge hole are staggered.

[0031] Specific, combined Figure 1-3 , prevent the roll film to be cut from being placed in the semicircular tube 2 and making the roll film located between the two partitions 3. The partitions 3 on both sides of the roll film can limit the film, which is beneficial for the stable rotation of the film in the semicircular tube 2 at a later stage. After being placed, one end of the roll film is pulled out from the discharge hole so that the roll film can be cut later.

[0032] A guide plate 10 located below the semicircular tube 2 is fixed on the mounting plate 1;

[0033] Specifically, the guide plate 10 plays a role in guiding the film.

[0034] The bidirectional transmission assembly includes a bidirectional gear conveyor belt 4, a PLC controller 9 is fixed on the mounting plate 1, the bidirectional gear conveyor belt 4 is electrically connected to the PLC controller 9, and two mounting grooves 11 are opened on the upper side of the bidirectional gear conveyor belt 4;

[0035] The bidirectional cutting assembly includes a moving block 5 and a blade 6. Two mounting blocks 12 are fixed on the moving block 5. The two mounting blocks 12 are respectively fixed in two mounting grooves 11. The blade 6 is fixed on the moving block 5 and is located obliquely below the guide plate 10. Both sides of the blade 6 are provided with cutting edges.

[0036] Specifically, the working interval time and running direction of the bidirectional gear conveyor belt 4 can be preset through the PLC controller 9, so as to control the working interval time and running direction of the moving block 5 and the blade 6, so as to realize automatic and bidirectional film cutting of the mechanism.

[0037] The cleaning assembly includes a wind force component 7 and a spray pipe 8. Two wind force components 7 are provided and are respectively fixed on both sides of the surface of the mounting plate 1. Two spray pipes 8 are provided and are respectively fixed to the air outlet ends of the two wind force components 7. The blade 6 corresponds to one of the spray pipes 8. Both wind force components 7 are electrically connected to the PLC controller 9.

[0038] Wherein, the wind power component 7 is an air pump or a fan;

[0039] Specifically, the working interval time of the wind power component 7 can be preset through the PLC controller 9. When the blade 6 is located under any air jet pipe 8, the PLC controller 9 will close the two-way gear conveyor belt 4 to stop the blade 6 from moving. At the same time, the PLC controller 9 will start the wind power component 7, and use the air pump or fan to draw the outside air into the air jet pipe 8 to form an airflow. Thereafter, the airflow is sprayed onto the blade 6 below it through the air jet pipe 8, thereby blowing away the debris on the blade 6, which is beneficial for the blade 6 to continue to maintain a good cutting state to avoid a decrease in cutting accuracy.
