Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping equipment, in particular to a device for bag production. BACKGROUND

[0002] In the process of bag production, it is often necessary to stamp various components, such as punching out specific shapes of leather or gaskets (such as round gaskets). Traditional manual or semi-automatic stamping production methods often have the following problems:

[0003] Firstly, the production efficiency is low and the degree of automation is low. The existing equipment often needs workers to manually place the stamping parts (such as leather or gasket blanks) one by one on the die, and then manually take them down and collect them after stamping. This manual feeding and unloading method not only has high labor intensity, but also has slow production rhythm, which becomes a bottleneck for improving production capacity.

[0004] Secondly, the positioning accuracy is difficult to guarantee. Manual placement of blanks is prone to positional deviation, resulting in non-uniform product size, irregular edges, and even scrap products, affecting the quality and consistency of the final bag product. Especially for small parts that require subsequent precise assembly, size deviation will cause assembly difficulties.

[0005] Thirdly, there are safety hazards. The hands of the operator need to frequently enter the working area of the stamping machine and come into close contact with the stamping die and punch, although there are safety protection devices, but there is still a potential risk of mechanical injury due to misoperation or equipment failure.

The rotating table 1 is provided with a die hole 23 at the bottom of each stamping die 2, which is matched in size with the bottom of the lower die 54, so that the jacking cylinder 55 can be embedded into the bottom of the lower die 54 through the die hole 23 when jacking, forming a stable cavity.

[0055] Working process:

[0056] Initial state: The rotating table 1 is stationary, an empty stamping die 2 is located at the feeding station, and the lifting cylinder 31 of the feeding component 3 is in the upper position, and the opening and closing rod 34 is in the open state.

[0057] Feeding:

[0058] The external driving part (not shown in the figure) drives the fixed roller 422 to rotate, and drives the wrapping belt 421 to start running. The push piece drags the bottommost one of the punched parts from the bottom of the storage cavity 41. At this time, the telescopic cylinder 426 is in the extended state, and the punched part is conveyed to the position directly below the feeding part 3. Then, the opening and closing assembly 33 drives the opening and closing rods 34 to approach each other, supports the punched part, and then the telescopic cylinder 426 retracts. In order to ensure that the punched part is not brought back when the telescopic cylinder 426 retracts, the inner side of the supporting part 341 is provided with a chamfer, so that the height of the punched part on the supporting part 341 is greater than the height of the punched part on the wrapping belt 421;

[0059] The lifting cylinder 31 drives the whole feeding part 3 to descend, and the supporting part 341 of each opening and closing rod 34 is inserted into the corresponding track groove 21 of the punching die 2. Then, the opening and closing assembly 33 drives the opening and closing rod 34 to open along the track groove 21, so that the punched part falls on the punching die 2. The lifting cylinder 31 drives the whole feeding part 3 to ascend and reset.

[0060] Rotation and punching: the rotating table 1 rotates to send the punched die 2 that has been fed to the punching station. The puncher 5 acts, the punch head 52 drives the upper die 53 to press down, cooperates with the punching die 2 and the lower die 54 and the lifting cylinder 55 to complete the punching.

[0061] Discharging and collecting: the rotating table 1 rotates again to send the punched die 2 that has been punched to the discharging station. The closing cylinder 74 of the turnover part 7 acts to close the upper cover 72 and the lower cover 73. Then, the turnover motor 77 starts to drive the punched die 2 to turn over. The finished product in the punched die 2 falls into the finished product collecting box 6 under the action of gravity. Finally, the turnover part 7 resets and releases the punched die 2.

[0062] Cycle: the rotating table 1 continues to rotate to send the empty punched die 2 to the feeding station to start the next cycle. It should be noted that the feeding station, the punching station and the discharging station are spaced apart by a plurality of punched dies 2.

[0063] Although the present application is specifically shown and described in connection with the preferred embodiments, those skilled in the art should understand that various changes in form and details can be made to the present application without departing from the spirit and scope of the present application as defined in the appended claims.
