Description

Technical Field

[0001] The utility model relates to the field of packaging of blow molding machines, in particular to a packaging device on a blow molding machine. Background Art

[0002] A blow molding machine is a plastic processing machine. After spraying the plastic, the machine uses the wind force to blow the plastic into a mold cavity of a predetermined shape, thus creating a product. This type of machine is called a blow molding machine. Especially when blow-molding hollow products, the softened plastic must first be sealed to create a cavity in the center of the softened material, which is then extruded and blown into shape. Existing sealing methods often rely on manual operation, which is prone to accidents and poses a low safety risk. Manual operation is also time-consuming, labor-intensive, and inefficient, making automated, continuous production impossible. Utility Model Content

[0021] The present invention is described in further detail below with reference to the accompanying drawings.

[0022] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0023] As attached Figure 1-5 The upper sealing device for a blow molding machine shown in FIG. 1 includes an upper sealing assembly and a drive assembly. The upper sealing assembly is positioned adjacent to the extruder 4.1 of the blow molding machine and comprises two hingedly coupled clamping members 1 for clamping the blow-molded product. The drive assembly is configured to drive the two clamping members 1 to close or expand. The cooperation between the upper sealing assembly and the drive assembly enables the automatic sealing of the blow-molded product, achieving stable and reliable sealing. While increasing the degree of automation, the device features a simple structure and convenient assembly and setup. This also effectively reduces manual intervention, lowering labor costs and the risk of accidents.

[0024] On the basis of the above, the upper encapsulation assembly also includes an assembly plate 1.3, and both clamping members 1 are hinged to the assembly plate 1.3. The ends of the two clamping members 1 hinged to the assembly plate 1.3 are each provided with a synchronization gear 1.4. The two synchronization gears 1.4 engage with each other, thereby facilitating the assembly and disassembly of the clamping members 1 and ensuring stable and smooth operation. Specifically, the clamping member 1 includes a clamping plate 1.1, each end of which is provided with a connecting plate 1.2, and a synchronization gear 1.4 is fixedly mounted on the end of the connecting plate 1.2 away from the clamping plate 1.1. The coordination of the provided connecting plate 1.2, the clamping plate 1.1, and the synchronization gear 1.4 ensures the synchronization of the opening and closing of the two clamping members 1, thereby ensuring the clamping and sealing effect.

[0025] It is worth mentioning that the connecting plates 1.2 on both sides of the clamping plate 1.1 are fixed with synchronous gears 1.4, and the two matching synchronous gears 1.4 are meshed with each other. The synchronous gears 1.4 on both sides can further ensure the smoothness and stability of the clamping of the clamping member 1.

[0026] To enhance the usability of the clamping member 1, adjustment holes 1.21 are provided at the ends of the two connecting plates 1.2 where they mate with the clamping plate 1.1. Clamping plates 1.1 are secured with adjustment seats, which are threaded with adjustment bolts 1.6 that penetrate the corresponding adjustment holes 1.21. The adjustment seats 1.5, adjustment holes 1.21, and adjustment bolts 1.6 cooperate to adjust the position of the clamping plates 1.1 on the connecting plates 1.2, thereby enhancing the precision of the clamping seal. Since blow molding machines primarily soften plastic by heating, excessive waste can significantly increase costs and energy consumption. Therefore, this design effectively reduces waste and energy consumption.

[0027] To further ensure the stability of the splint 1.1, the connecting plate 1.2 is provided with two adjustment holes 1.21 side by side, and the adjustment seat is provided with two corresponding adjustment bolts 1.6. The cooperation between the two adjustment holes 1.21 arranged side by side and the corresponding adjustment bolts 1.6 can effectively improve the stability of the splint 1.1 after adjustment.

[0028] The drive assembly of the present invention includes a driver 2, whose telescopic shaft 2.1 is hingedly coupled to one of two clamping members 1. Specifically, the blow molding machine includes a work platform 5 and an extrusion barrel 4 provided with an extrusion port 4.1. The work platform 5 is provided with a mounting plate 3, which is hingedly coupled to the driver. An assembly plate 1.3 is secured to the extrusion barrel 4. The two clamping members 1 are located on either side of the extrusion port 4.1, thereby effectively improving the ease of installation of the upper encapsulation assembly and the drive assembly, and providing convenient use.

[0029] It should be further explained that the thickness of the opposite side portions of the two plywood 1.1 of the present invention gradually decreases, and the edges have a smooth transition. The smooth transition can avoid damage to the plastic extrusion material during clamping and sealing, and the gradually decreasing thickness has a greater pressure under the same driving force, thereby ensuring sealing reliability.

[0030] Those skilled in the art will appreciate that the embodiments of the present invention described above and shown in the accompanying drawings are intended only as examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and illustrated in the embodiments. Any variations or modifications may be made to the embodiments of the present invention without departing from the principles described.
