[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only schematically showing the basic structure of the present invention, so they only show the components related to the present invention.

[0030] For the inserting pocket mechanism, please refer to Figures 1-3 As shown, it includes: a support member 100, a triangular inserting piece 200, a driving assembly 300, and a swing arm 400.

[0031] The support member 100 plays a role of support and bearing. The support member 100 is in a plate shape, and a first slide rail 110 is horizontally arranged on the support member 100.

[0032] The triangular inserting piece 200 is connected to the first slide rail 110 through a slider 120 and can reciprocate linearly along the first slide rail 110;

[0033] The driving assembly 300 is assembled on the support member 100;

[0034] The swing arm 400 is connected to the driving assembly 300 and the triangular inserting piece 200;

[0035] The driving assembly 300 drives the swing arm 400 to swing, and the triangular inserting piece 200 is driven to move along the first slide rail 110 during the swinging process of the swing arm 400.

[0036] As Figure 4 shown, the inserting pocket mechanism of the present utility model is applied to a packing machine, and particularly is used in cooperation with the sealing structure 00 of the packing machine; Figure 4 There are two groups of inserting pocket mechanisms in

[0037] Figure 4 , and they are symmetrically arranged left and right. When the two inserting pocket mechanisms operate, the two triangular inserting pieces 200 move towards each other along the first slide rail 110 to press a triangle on the packaging bag to be sealed, forming a triangular concave shape; then after the heat-sealing knife 01 of the sealing structure 00 heat-seals the bag mouth, the two triangular inserting pieces 200 move in the reverse direction along the first slide rail 110 to reset and leave the packaging bag.

[0038] In one implementation manner, the driving assembly 300 includes: a cylinder 310, a rack 320, a gear 330, and a gear shaft 340;

[0039] The cylinder 310 is installed on the support member 100, and the output shaft of the cylinder 310 is connected to the rack 320. When the output shaft moves linearly in a telescopic manner, the rack 320 is driven to reciprocate linearly;

[0040] The gear 330 meshes with the rack 320. The gear 330 is mounted on the support member 100 through a gear shaft 340, and a bearing can be provided at the connection between the gear shaft 340 and the support member 100. The cylinder 310 pushes the rack 320 to move linearly to drive the gear 330 to rotate.

[0041] Further, the first end of the swing arm 400 is fixedly connected to the gear shaft 340. When the gear 330 rotates, the swing arm 400 is driven to swing through the gear shaft 340.

[0042] A strip-shaped groove 410 is provided at the second end of the swing arm 400. The triangular insert 200 is provided with a pin 210 that is inserted into the strip-shaped groove 410, and the pin 210 moves along the strip-shaped groove 410. For the convenience of movement, a pulley 220 is provided on the pin 210.

[0043] The swing arm 400 pushes the triangular insert 200 to move linearly along the first slide rail 110.

[0044] Further, the front end of the triangular insert 200 is a tip. When the triangular insert 200 moves linearly outward along the first slide rail 110, the front end of the triangular insert 200 extends outward; combined with Figure 4 as shown, the front end of the triangular insert 200 extending outward means that the front end of the triangular insert 200 extends in the direction of inserting into the packaging bag.

[0045] By converting linear motion into curvilinear motion and finally converting it into the linear movement of the triangular insert 200 along the first slide rail 110, the present utility model realizes the smooth movement of the triangular insert 200, and the sealing effect of the packaging bag is better.

[0046] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
