When the bag body 8 is fixed to the clamping platform 5, the front end of the bag body 8 passes through the guide slope 55, and the guide slope 55 can provide positioning for the bag body 8, so that the bag body 8 can be fixed on the clamping platform 5 every time. position, to prevent position deviation from the bag body 8 when it is set on the bag body 9, which will affect the smoothness of bagging. Simultaneously, when the clamping platform 5 dragged the bag body 8 to move forward, the guide slope 55 could increase the contact area between the bag body 8 and the clamping platform 5 sides, preventing the front end of the bag body 8 from being cut by the side edge of the clamping platform 5 fracture.

The frame body is also provided with a baffle 11 at the end of the moving stroke of the clamping platform 5, and the clamping platform 5 is slidably connected with a push handle 72 when touching the baffle 11 to keep the pressure plate 71 away from the clamping platform. 5 trigger block 56.

When the clamping platform 5 moves to the end position of the moving stroke, the bag body 8 completes bagging. At this time, the trigger block 56 touches the baffle plate 11 and drives the pressure plate 71 away from the clamping platform 5. There is no need to manually loosen the clamp, which saves manpower. Also improved production efficiency.

A positioning block 57 is fixedly disposed on the clamping platform 5 , and a guiding notch 571 is provided at the bottom of the positioning block 57 , and the triggering block 56 is slidably engaged in the guiding notch 571 . The trigger block 56 is inserted into the guide notch 571 , and the guide notch 571 provides a guiding function for the trigger block 56 , so that the trigger block 56 is slidably connected with the clamping platform 5 along the moving direction of the clamping platform 5 .

The end surface of the trigger block 56 abutting against the bottom end of the handle 72 is a wedge-shaped surface 561 . When the trigger block 56 pushes the handle 72, the wedge-shaped surface 561 on the trigger block 56 can help it to push the handle 72 to swing, so that the pressure plate 71 is automatically moved away from the clamping platform 5, preventing the trigger block 56 and the handle 72 from being stuck. .

One end of the trigger block 56 close to the handle 72 is provided with a stop portion 562 that engages with the positioning block 57 . The stop part 562 is engaged with the positioning block 57, so that the trigger block 56 cannot escape outward along the guide gap 571, preventing the trigger block 56 from falling off during the movement of the clamping platform 5, and avoiding that the clamp cannot be automatically loosened after bagging is completed. .

The bottom of the handle 72 is provided with a wheel 721 abutting against the trigger block 56 . When the trigger block 56 pushes the handle 72 to swing, the rotating wheel 721 at the bottom of the handle 72 rubs against the trigger block 56 and rotates, so that the trigger block 56 is more smooth when pushing the handle 72 to swing.

A reset spring 58 for moving the trigger block 56 away from the handle 72 is disposed between the trigger block 56 and the clamping platform 5 . The end of the trigger block 56 away from the handle 72 is extended downwards with an extension part 563 , and the side of the extension part 563 facing the support platform 21 is provided with a mounting hole 5631 through which the return spring 58 penetrates.

The return spring 58 can make the trigger block 56 provide a cushioning effect when it touches the baffle plate 11, and at the same time, after the trigger block 56 pushes the handle 72 to loosen the clamping plate 71, the trigger block 56 can automatically reset under the return spring 58, without the operator's artificial Pull trigger block 56 out.

The extension part 563 is provided with a threaded hole 5632 communicating with the mounting hole 5631 , the threaded hole 5632 is internally threaded with an adjusting bolt 59 , and the screw end of the adjusting bolt 59 is fixedly connected with the return spring 58 . The return spring 58 tends to decrease in elasticity after being used for a long time, and the return spring 58 can be stretched to restore its elastic force by turning the adjusting bolt 59 .

The concrete work process of the semi-automatic bagging machine that the utility model relates to is as follows:

In the initial state, the clamping platform 5 is located close to the pre-stretched bag device 2, first put the kit 9 to be placed between the two rollers 52 along the positioning gap 53 on the clamping platform 5, and push the kit 9 to make it The end moves to the side of the clamping platform 5 close to the pre-stretched bag device 2 , and the other end of the sleeve 9 is placed in the limiting portion 323 of the positioning member 32 .

Then put the bag body 8 completely on the bag support rod 22, and use the pulley 23 to be stuck in the limit gap 221 of the bag support rod 22 to fix the bag support rod 22, and then extend the scissors to the bag support rod 22 Cut two slits at the front end of the bag body 8 in the auxiliary gap 223 at the tail end, place the front end of the bag body 8 on the set 9, and pull the upper half cut out of the front end of the bag body 8 onto the clamping platform 5, The front end of the bag body 8 is pressed tightly on the clamping platform 5 by manually turning the handle 72 in conjunction with the pressing plate 71 .

Start the motor 64, and the first transmission belt 61 drives the clamping platform 5 to move along the guide rail 4, and at the same time, the bag body 8 is gradually placed on the waiting kit 9. When the clamping platform 5 moves to the positioning member 32, the roller 52 below the clamping platform 5 pushes the limit block 322 to rotate, and after the clamping platform 5 passes the positioning member 32, the limit block 322 rotates under the action of the tension spring 33 reset.

When the clamping platform 5 moves to the end of the stroke, the trigger block 56 on the clamping platform 5 abuts against the baffle 11, and the trigger block 56 pushes the lower part of the handle 72 to swing, so that the linkage pressure plate 71 moves away from the clamping platform 5 to release the bag body 8 .

Finally, the bag body 8 at the two ends of the package 9 is manually cut and sealed to complete the bagging process.

The foregoing is only a partial implementation of the utility model, and it should be pointed out that for those of ordinary skill in the art, some improvements and modifications can also be made without departing from the principle of the utility model. Retouching should also be regarded as the scope of protection of the present utility model.
