Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0024] According to one embodiment of the utility model, Figure 1-Figure 4 As shown: This embodiment provides a food packaging bag cutting mechanism 100, including a support frame 101, an operating table 102 is arranged on the support frame 101, support plates 103 are arranged on the left and right sides of the operating table 102, and the cutting mechanism 100 is arranged on the support plate 103, characterized in that: the two sides of the cutting mechanism 100 are provided with moving components 200;

[0025] The moving assembly 200 includes a support seat 201 connected to the inner wall of the support plate 103, a groove 1 202 is provided at the bottom of the support seat 201, a groove 203 is symmetrically provided on the inner wall of the support seat 201, a driving motor 204 is arranged in the groove 203, a through hole penetrating the left and right side walls of the support seat 201 is provided in the groove 203, a transmission shaft 205 penetrating the through hole is provided at the end of the driving motor 204, a relatively raised guide rail 206 is provided on the side wall of the support plate 103, a roller 207 connected to the transmission shaft 205 is provided in the guide rail 206, an L-shaped fixing block 208 is provided on the upper part of the support seat 201, a slide groove 209 is provided on the outer wall of the support plate 103, and a slider 210 connected to the lower side of the fixing block 208 is provided in the slide groove 209.

[0026] When the staff needs to move the slitting assembly, the staff only needs to use tools to remove the bolts on the limit block 213, and then start the drive motor 204 in the support seat 201. The drive motor 204 is a three-phase motor. The high-voltage direct current is converted into alternating current through the motor control unit, and the three-phase power input terminal on the drive motor 204 is used to supply the power machine. The input ends of the three-phase power input terminals are white, black, and red respectively, and the other end shares the output end with their respective stator coils. When the three-phase power is input to each input end, a rotating magnetic field is generated in the stator, and an induced current is generated in the rotor. Under the action of the magnetic field force, the rotor starts to rotate, and the rotation of the rotor drives the transmission shaft 205 of the drive motor 204 to rotate. The transmission shaft 205 is connected to a roller 207, which drives the roller 207 to rotate. The roller 207 is set in a guide groove, and the roller 207 moves along the guide groove. The two drive motors 204 are in series and work at the same time. The roller 207 drives the support seat 201 to move in the workbench, and the support seat 20 1 is provided with an L-shaped fixed block 208, and a dovetail slider 210 is provided on the lower side of the fixed block 208. The dovetail slider 210 is slidably arranged in the dovetail slot 209 on the outer wall of the support plate 103. The support seat 201 moves to drive the fixed block 208 to move, and the fixed block 208 drives the dovetail slider 210 to move in the dovetail slot 209. The dovetail slot 209 and the dovetail slider 210 can make the fixed block 208 more stable when moving and not easy to tilt. After the slitting mechanism 100 reaches the expected position, the driving motor 204 is turned off, and the limit blocks 213 are fixed to the positions on both sides of the dovetail slider 210 with bolts. The limit blocks 213 can prevent the dovetail slider 210 from shifting and causing the slitting mechanism 100 to shift as a whole, resulting in inaccurate cutting and affecting product quality. The moving component 200 has a simple structure and is easy to operate, which effectively improves the efficiency of changing the position of the cutting component when producing products of different sizes, reduces the work content of the staff, reduces the labor intensity of the staff, and improves the work efficiency of the staff.

[0027] The use of this utility model:

[0028] When the production of a food packaging bag is completed and food packaging bags of different sizes need to be produced, the staff only needs to use tools to remove the bolts on the limit block 213, and then start the drive motor 204 in the support seat 201. The drive motor 204 is a three-phase motor. The high-voltage direct current is converted into alternating current through the motor control unit, and the three-phase power input terminal on the drive motor 204 is used to supply the power to the machine. The input ends of the three-phase power input terminals are white, black, and red respectively, and the other end shares the output end with their respective stator coils. When the three-phase power is input to each input end, a rotating magnetic field is generated in the stator, and an induced current is generated in the rotor. Under the action of the magnetic field force, the rotor starts to rotate, and the rotation of the rotor drives the transmission shaft 205 of the drive motor 204 to rotate. The transmission shaft 205 is connected to a roller 207, which drives the roller 207 to rotate. The roller 207 is set in a guide groove, and the roller 207 moves along the guide groove. The two drive motors 204 The two parts are in series relationship and work at the same time. The roller 207 drives the support seat 201 to move in the workbench. An L-shaped fixed block 208 is arranged on the support seat 201. A dovetail slider 210 is arranged on the lower side of the fixed block 208. The dovetail slider 210 is arranged in the dovetail slot 209 on the outer wall of the support plate 103. The movement of the support seat 201 drives the fixed block 208 to move, and the fixed block 208 drives the dovetail slider 210 to move in the dovetail slot 209. After the slitting mechanism 100 reaches the expected position, the driving motor 204 is turned off, and the limit blocks 213 are fixed to the positions on both sides of the dovetail slider 210 with bolts to prevent the support seat 201 from shifting during cutting, resulting in inaccurate cutting; the moving component 200 has a simple structure and is easy to operate. It effectively improves the efficiency of changing the position of the cutting component when producing products of different sizes, reduces the work content of the staff, reduces the labor intensity of the staff, and improves the work efficiency of the staff.
