[0058] The working principle of the trolley for the rotatable sealing strip product for easy punching described in this embodiment is as follows:

[0059] 1): The lifting drive mechanism 32 drives the trolley layer strip rotating drive mechanism 312 to descend, and the third groove 31211 on the upper track wall plate 3121 in the trolley layer strip rotating drive mechanism 312 and the second positioning groove 31242 on the layer strip semicircular gear 3124 are respectively correspondingly engaged with the convex portion 31111 on the lower track wall plate 3111 in the trolley rotating conveying mechanism 311 and the first positioning protrusion 31142 on the strip loading semicircular gear 3114, and the strip loading trolley is in a locked state at this time; the upper and lower semicircular tracks of the upper and lower parts and the layer strip semicircular gear 3124 and the strip loading semicircular gear 3114 are combined into one, and the layer strip assembly 3125 presses and fixes the sealing strip;

[0080] The working principle of the automatic punching and cutting equipment for sealing strip products described in this embodiment is as follows: 1): the product is mounted on the strip mounting sheet metal 31171 under the positioning guidance of the strip mounting positioning module 5;

[0081] 2): The conveying drive motor 25 drives the synchronous belt main wheel 22 to rotate. During the operation of the synchronous belt main wheel 22, the synchronous belt 24 and the synchronous belt driven wheel 23 are rotated;

[0082] 3): The trolley rotating conveying mechanism 311 is driven by the synchronous belt 24 to the punching standby position. At the same time, the trolley rotating conveying mechanism 311 is guided by the mutual cooperation of the annular inclined guide rail 28 and the inclined guide wheel 3116 during the movement, and the offset gap in the left and right directions is eliminated, which lays a good foundation for the subsequent engagement with the trolley pressure strip rotating driving mechanism 312;

[0083] 4): The lifting drive mechanism 32 drives the trolley pressure strip rotating drive mechanism 312 to descend, and the third groove 31211 on the upper track wall plate 3121 in the trolley pressure strip rotating drive mechanism 312 and the second positioning groove 31242 on the pressure strip semicircular gear 3124 are respectively correspondingly engaged with the convex portion 31111 on the lower track wall plate 3111 in the trolley rotating conveying mechanism 311 and the first positioning protrusion 31142 on the strip loading semicircular gear 3114, and the strip loading trolley is in a locked state; the upper and lower semicircular tracks of the upper and lower parts and the pressure strip semicircular gear 3124 and the strip loading semicircular gear 3114 are combined into one, and the pressure strip assembly 3125 presses the sealing strip onto the strip loading sheet metal 31171; at the same time, the trolley rotating conveying mechanism 311 is locked in the front, back, left and right directions under the downward pressure engagement of the trolley pressure strip rotating drive mechanism 312;

[0084] 5): The rotary drive motor 31261 of the trolley layer strip rotary drive mechanism 312 drives the power gear 31262 to rotate, and the power gear 31262 drives the gear rotating assembly of the layer strip semicircular gear 3124 and the installation strip semicircular gear 3114, which are combined into one, to rotate along the track that is combined into one of the upper semicircular track and the lower semicircular track, and stops after the product is rotated to the required angle;

[0085] 6): The integrated punching device 4 moves forward to punch the product. After the punching is completed, the integrated punching station 4 moves backward, that is, the punching plate 471 moves downward under the drive of the punching drive mechanism 472 and collides with the force block 434 of the single-sided multi-cavity punching tool. The force block 434 drives the punching assembly 433 to punch until the upper power limit reference block 473 installed on the punching plate 471 and the lower power limit block 412 on the single-sided multi-cavity punching tool are supported. At this time, the punching plate 471 stops moving downward, and the punching of the sealing strip is completed. Then, the punching plate 471 returns upward under the drive of the punching drive mechanism 472;

[0086] 7): The rotary drive motor 31261 of the trolley strip rotating drive mechanism 312 then drives the rotating part of the rotary strip loading trolley 3 to rotate back to the initial state, and the circular transport module 2 then transports the trolley to the next position, and then the entire product punching is completed in this reciprocating manner.

[0087] It should be noted that before the equipment is working, it is necessary to select a suitable single-cavity tooling according to the product to be cut, and move each single-cavity tooling 44 forward in turn under the guidance of the left and right limit members 410 and insert it into the front positioning block 47, and then the rear clamping block 48 is pressed against each single-cavity tooling 44 in turn and locked. At this time, the single-sided multi-cavity punching tooling assembly is completed.

[0088] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
