The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] like Figures 1 to 8 A packaging bag clamping assembly comprises: a first assembly plate 1, a second assembly plate 2 and a clamping mechanism 3, wherein the second assembly plate 2 is arranged on the upper end of the first assembly plate 1, and the clamping mechanism 3 is symmetrically installed between the first assembly plate 1 and the second assembly plate 2, and the clamping mechanism 3 comprises a biasing rod 31, a biasing plate 32 and a clamping block 33, and two biasing rods 31 are symmetrically fixedly connected to the inner wall in the middle of the first assembly plate 1 and the second assembly plate 2, and the central round rod surface of the biasing rod 31 is rotatably connected with the biasing plate 32, and the surface of the biasing plate 32 close to the biasing rod 31 is fixedly connected with the clamping block 33, and the clamping block 33 is located on one side of the biasing rod 31.

[0029] In this embodiment, by starting the driving mechanism 5, the transmission mechanism 4 is driven to move toward the clamping mechanism 3, driving the offset plate 32 to approach the U-shaped grooves of the first assembly plate 1 and the second assembly plate 2, and driving the clamping block 33 to clamp the packaging bag firmly.

[0030] As attached Figure 5 As shown, a transmission mechanism 4 is symmetrically installed in the middle of the first assembly plate 1 and the second assembly plate 2, and the transmission mechanism 4 is located on the side of the clamping mechanism 3 away from the U-shaped groove of the first assembly plate 1 and the second assembly plate 2. The transmission mechanism 4 includes a limit rod No. 1 41, a moving plate 42, a three-link transmission rod No. 1 43 and a linkage plate No. 1 44. The middle inner wall of the first assembly plate 1 and the second assembly plate 2 is symmetrically fixedly connected with two limit rods No. 1 41, and the limit rod No. 1 41 is located on the side of the offset plate 32 away from the bias rod 31. The limit rod No. 1 41 is provided with a displacement rod on the side close to the offset plate 32. The movable plate 42, the movable plate 42 is rotatably connected to the inner walls of the two circular holes close to the offset plate 32 with a three-way rotating transmission rod No. 1 43, the round rod surface of the three-way rotating transmission rod No. 1 43 is symmetrically rotatably connected to the interlocking plate No. 1 44, and the interlocking plate No. 1 44 is located at the upper and lower ends of the movable plate 42, the interlocking plate No. 1 44 is rotatably connected to the round rod surface of the limit rod No. 1 41 away from the circular holes of the three-way rotating transmission rod No. 1 43. In this embodiment, the driving mechanism 5 drives the movable plate 42 to approach the offset plate 32, and the movable plate 42 moves in the direction of the offset plate 32, providing drive for the clamping block 33 to clamp the packaging bag.

[0031] As attached Figure 5 and Figure 6 As shown, the transmission mechanism 4 also includes a linkage plate No. 2 45 and a double transmission rod No. 1 46. The round rod surface of the triple transmission rod No. 1 43 is symmetrically rotationally connected with the linkage plate No. 2 45, and the linkage plate No. 2 45 is located at the upper and lower ends of the offset plate 32. The linkage plate No. 2 45 is rotationally connected with the double transmission rod No. 1 46 away from the inner wall of the round hole of the linkage plate No. 1 44. The center round rod surface of the double transmission rod No. 1 46 is rotationally connected to the inner wall of the round hole of the offset plate 32 away from the offset rod 31.

[0032] In this embodiment, when the movable plate 42 approaches the offset plate 32, it drives the triple-rotating transmission rod No. 1 43 to move in the direction close to the limit rod No. 1 41. Since the linkage plate No. 1 44 and the linkage plate No. 2 45 are rotatably connected to the triple-rotating transmission rod No. 1 43, the linkage plate No. 1 44 is limited by the limit rod No. 1 41 and tends to be perpendicular to the movable plate 42. The linkage plate No. 2 45 cooperates with the double-rotating transmission rod No. 1 46 to move the offset plate 32 toward the direction of the U-shaped groove of the first assembly plate 1 and the second assembly plate 2.

[0033] As attached Figure 7 As shown, a driving mechanism 5 is fixedly installed in the middle of the first assembly plate 1 and the second assembly plate 2, and the driving mechanism 5 is located on the side of the transmission mechanism 4 away from the clamping mechanism 3. The driving mechanism 5 includes an electric push rod 51 and a driving block 52. The middle inner walls of the first assembly plate 1 and the second assembly plate 2 are fixedly connected with the electric push rod 51, and the moving end of the electric push rod 51 is fixedly connected with the driving block 52. In this embodiment, the electric push rod 51 is extended to drive the driving block 52 to move toward the direction of the U-shaped groove of the first assembly plate 1 and the second assembly plate 2, providing drive for the clamping block 33 to clamp the packaging bag. The electric push rod 51 contracts, the driving block 52 is reset, and the clamping block 33 places the packaging bag on the conveyor belt.

[0034] As attached Figure 8As shown, the driving mechanism 5 also includes a limit rod No. 2 53, a triple transmission rod No. 2 54, a linkage plate No. 3 55, a double transmission rod No. 2 56, a round-edge triangular plate 57 and a triple transmission rod No. 3 58. The middle inner wall of the first assembly plate 1 and the second assembly plate 2 is symmetrically fixedly connected with the limit rod No. 2 53, and the limit rod No. 2 53 is located on both sides of the driving block 52. The inner walls of the two circular holes of the driving block 52 are rotatably connected with the triple transmission rod No. 2 54. The circular rod surface of the triple transmission rod No. 2 54 is symmetrically rotatably connected with the linkage plate No. 3 55, and the linkage plate No. 3 55 is located at the upper and lower ends of the driving block 52. The linkage plate No. 3 55 is rotatably connected with the double transmission rod No. 2 56 away from the inner wall of the circular hole of the driving block 52. The circular rod surface of the double transmission rod No. 2 56 is symmetrically rotatably connected with the round-edge triangular plate 57, and the round-edge triangular plate 57 is located at the linkage plate No. 3 55 away from the double transmission rod No. 2 56. On one side, the circular hole of the round-edged triangular plate 57 close to the electric push rod 51 is rotatably connected with the circular rod surface of the limit rod No. 2 53, and the movable plate 42 is rotatably connected with the triple transmission rod No. 3 58 on the inner wall of the circular hole close to the round-edged triangular plate 57, and the circular rod surface of the triple transmission rod No. 3 58 is rotatably connected with the inner wall of the circular hole of the round-edged triangular plate 57 close to the movable plate 42. In this embodiment, when the driving block 52 moves in the direction of the U-shaped groove of the first assembly plate 1 and the second assembly plate 2, since the inner wall of the circular hole of the driving block 52 rotates with the triple transmission rod No. 2 54, the triple transmission rod No. 2 54 drives the linkage plate No. 3 55 to move in the direction of the U-shaped groove of the first assembly plate 1 and the second assembly plate 2, and after the transmission of the double transmission rod No. 2 56, the round-edged triangular plate 57 rotates due to the limiting of the limit rod No. 2 53, and the triple transmission rod No. 3 58 on the inner wall of the round-edged triangular plate 57 moves the movable plate 42 toward the direction of the clamping mechanism 3.

[0035] As attached Figure 3 As shown, four reinforcement rods 6 are symmetrically fixedly connected to the upper surface of the first assembly plate 1, and the top of the reinforcement rod 6 is fixedly connected to the lower surface of the second assembly plate 2. In this embodiment, the reinforcement rods 6 firmly connect the upper surface of the first assembly plate 1 and the lower surface of the second assembly plate 2 and provide stable support.
