Description

Technical Field

[0001] This application relates to the field of plastic packaging bag forming technology, specifically to a plastic packaging bag forming device. Background Technology

[0002] Plastic packaging bags are widely used packaging materials with diverse and crucial functions. Their protective function is significant, isolating food and daily necessities from impact and compression during transportation and storage. Some composite packaging bags can block water, oxygen, and light, extending the shelf life of food and preventing medicines from getting damp and clothing from accumulating dust. They also offer excellent convenience, being lightweight and often featuring handles for easy carrying. They can store loose items, saving space and making them easy to access. In terms of information delivery, product information can be printed on the bag surface, helping consumers understand the product and promoting the brand, enhancing brand recognition. In food packaging, many plastic bags have excellent sealing properties, preventing air from oxidizing; for example, vacuum bags can extend the shelf life of meat and cooked foods.

[0003] Patent publication number "CN220661691U" discloses "a blow molding equipment for plastic packaging bags", which includes a machine housing. An upper mounting housing is located on one side of the machine housing, and a blow molding tube is located at the bottom of the mounting housing. A strip groove is formed in the middle of one side of the machine housing. The inner wall of the strip groove is connected to the sides of two blow molding shells via an adjusting component. Auxiliary components are provided on the top sides of each of the two blow molding shells. A motor, in conjunction with a threaded rod and bearings, drives two sliders with oppositely arranged threaded openings to move within the strip groove. The two sliders, in conjunction with two arc-shaped blocks, move the two blow molding shells, separating them from the two auxiliary shells to facilitate the removal of the internal plastic packaging bags. Several electric telescopic rods drive several connecting rods to move within several insertion holes on the top of the two blow molding shells. The connecting rods also drive the two auxiliary shells to slide along the inner walls of the two arc-shaped grooves on the surfaces of the two blow molding shells, increasing the space in the blow molding chamber and facilitating the blow molding of packaging bags of different sizes.

[0004] In the aforementioned patent, the device relies mainly on manual removal of the blow-molded packaging bags during the bag collection process. Manual collection is not only inefficient and time-consuming, but also may damage the packaging bags due to improper operation, affecting product quality.

[0005] Therefore, this utility model provides a plastic packaging bag forming equipment to solve the above problems. Utility Model Content

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this application provides the following technical solution: a plastic packaging bag forming device, comprising a table, with a collecting mechanism and an auxiliary mechanism respectively arranged above the table.

The rotating screw 32 will drive the moving block 34 screwed on the outside to move. The moving block 34 can drive the servo electric cylinder 35 installed on the top surface to move synchronously. Then, after the external negative pressure device connection end is installed on the bottom connection end of the suction cup 36 installed at the output end of the servo electric cylinder 35, the suction cup 36 with negative pressure can effectively adsorb the blow-molded packaging bag, realize safe collection, and reduce time waste. One end of the screw 32 is rotatably connected to the inner wall of one end of the sliding groove 31. The sliding groove 31 is opened on the surface of the table 1 and penetrates through the interior.

[0034] The bottom surface of the servo electric cylinder 35 of the receiving mechanism 3 is slidably connected to the surface of the table 1, and the two sides of the moving block 34 are slidably connected to the inner walls of the two sides of the sliding groove 31.

A second servo motor 53 is fixedly installed at the other end of the bidirectional lead screw 52. A first housing 54 and a second housing 55 are screwed to the outer side of the bidirectional lead screw 52, ​​respectively. Servo electric actuators 56 are fixedly installed on the top surfaces of the first housing 54 and the second housing 55, respectively. The output end of the servo electric actuator 56 is slidably connected through the top surface and top wall of the first housing 54 and the second housing 55, respectively.

[0039] Working principle: The collecting mechanism 3 drives the screw 32 installed at the output end to rotate through the first servo motor 33. The rotating screw 32 drives the moving block 34 screwed on the outside to move. The moving block 34 can drive the servo electric cylinder 35 installed on the top surface to move synchronously. Then, after the external negative pressure device connection end is installed on the bottom connection end of the suction cup 36 installed at the output end of the servo electric cylinder 35, the suction cup 36 with negative pressure can effectively adsorb the blow-molded packaging bag, realize safe collection, and reduce time waste. One end of the screw 32 is rotatably connected to the inner wall of one end of the sliding groove 31. The sliding groove 31 is opened on the surface of the table 1 and runs through the interior.

[0040] The tabletop 1 bears the weight of the equipment through the support frame 2 installed on the bottom. It is designed with multiple storage boxes for classifying and storing tools and parts. The bottom of the support frame 2 is equipped with anti-slip pads 6, which effectively improves the stability of the equipment by increasing contact friction and preventing sliding and displacement during use.

[0041] The auxiliary mechanism 5 drives the bidirectional lead screw 52 at the output end to rotate via the second servo motor 53. One end of the bidirectional lead screw 52 is rotatably connected to the inner wall of one end of the outer frame 51, causing the first housing 54 and the second housing 55, which are respectively screwed to the outer side, to move accordingly. Through the mutual movement of the first housing 54 and the second housing 55, they are locked on both sides of the output end of the machine body 4 to form a stable structure, providing a reliable molding environment for the internal blow molding process. At the same time, the servo electric push rods 56 on the top surface of the two housings start the output end to drive the first inner housing 57 and the second inner housing 58 to slide on the inner side of the corresponding housing. Through the up and down sliding of the inner housing, the blow molding chamber space can be flexibly expanded during the blow molding process, thereby adapting to the blow molding requirements of packaging bags of different sizes.
