Description

Technical Field

[0001] The utility model relates to the technical field of blister box forming, in particular to an integrated blister box forming device. Background Art

[0002] Blister box is a plastic packaging box made by the blister process. The basic principle is to soften the smooth plastic hard sheet by heating, and then use vacuum to adsorb it on the mold surface. After cooling, it forms the desired shape. Blister box is widely used in plastic packaging, lighting, advertising, decoration and other industries because of its light weight, low cost and excellent protective performance.

[0003] The patent with the patent authorization announcement number CN216683320U discloses a blister box forming mold. This patent can greatly cushion and offset the vibration generated when the device is running through the stabilizing assembly of the stabilizing plate and the connecting rod, avoiding damage to the equipment caused by large-scale vibration, and preventing large-scale vibration from causing adverse effects on the forming of the blister box. It solves the poor stability of traditional forming molds, but there are still some shortcomings in actual use. The forming mold of this patent requires manual demolding. However, during the production process, vacuum is required to allow the plastic sheet to be adsorbed in the mold cavity. After cooling and shaping, the fit between the blister box and the mold cavity is very tight, which makes demolding more inconvenient and easily causes product damage or deformation, affecting production efficiency and product quality.

[0004] Therefore, it is urgent to provide a blister box integrated forming device that can achieve automatic demoulding. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0022] Example 1: Please refer to Figure 1-Figure 3 , a blister box integrated molding device, including a support frame 1, a placement table 2, a shell 3, a heater 4, a cylinder 5, an upper mold 6, a lower mold 7, a telescoping device 8, a connecting frame 9, a push rod 10, a top cover 16 and a cushion 17, the placement table 2 is supported by four support frames 1 arranged around it, and the side edges of the placement table 2 are wrapped with cushions 17, which can effectively absorb and buffer external impacts, prevent the placement table 2 from contacting with hard objects during transportation or operation, and avoid scratches or scratches, a shell 3 is provided on the table top of the placement table 2, and a discharge port and a feed port are respectively provided on the left and right sides of the shell 3, a heater 4 for heating the plastic sheet is provided above the feed port of the shell 3, and four cylinders 5 are installed on the shell 3, A top cover 16 is provided on the top of the shell 3 for protecting the cylinder 5, reducing the wear of the cylinder 5, extending its service life and reducing maintenance costs. The movable rod of the cylinder 5 is jointly provided with an upper mold 6. A lower mold 7 is provided inside the shell 3 to cooperate with the upper mold 6. The lower mold 7 is designed with six mold cavities and is connected to the external vacuum pump. A pair of telescoping devices 8 are installed on the table top of the placing table 2. The telescopic rods of the telescoping devices 8 are jointly provided with a connecting frame 9. Six groups of ejector rods 10 are provided on the connecting frame 9. Each group of ejector rods 10 corresponds to a mold cavity on the lower mold 7. Through the operation of the telescoping device 8, the connecting frame 9 drives the ejector rods 10 to rise, so that the finished blister box in the lower mold 7 can be ejected to achieve automatic demoulding.

[0023] First, the plastic sheet is fed into the device from the feed port. During the conveying process, the heater 4 located above the feed port will heat the plastic sheet to make it reach a suitable softening temperature. When the plastic sheet reaches the required temperature, under the action of the cylinder 5, the upper mold 6 moves downward and accurately presses the heated and softened plastic sheet into the lower mold 7. At the same time, the external vacuum exhauster connected to the lower mold 7 will extract the air in the lower mold 7 to create a negative pressure environment. This negative pressure effect enables the plastic sheet to fit tightly to the surface of the lower mold 7 and be accurately formed into the required blister box shape according to the shape of the mold. After the blister box is completely shaped, the cylinder 5 is started again, driving the upper mold 6 to move upward and return to its initial position. At this time, the telescopic device 8 starts to work, and the telescopic rod on it pushes the connecting frame 9 to rise vertically, so that the ejector 10 on the connecting frame 9 ejects the already formed blister box from the lower mold 7 to achieve demoulding. Finally, the formed blister box is smoothly removed from the device through the discharge port, thus completing the integrated molding process of the entire blister box.

[0024] Example 2: Based on Example 1, please refer to Figure 4 , also includes a fixing frame 11, an air cooler 12, a nozzle 13 and a guide frame 1301. A fixing frame 11 is provided above the discharge port of the shell 3, and four air coolers 12 are mounted on the fixing frame 11. The air coolers 12 are commonly connected to a nozzle 13. A guide frame 1301 is provided on the table below the nozzle 13 for guiding cold air to prevent the cold air from escaping and maintain efficient cooling.

[0025] When the blister box is sent out of the device from the discharge port, the air conditioner 12 starts to work, generating a large amount of cold air. The cold air is evenly sprayed on the surface of the formed blister box through the nozzle 13, quickly taking away the heat, accelerating the cooling speed of the blister box, helping to fix the shape of the blister box, preventing deformation or shrinkage caused by excessive temperature, and ensuring the molding effect and dimensional stability of the blister box.

[0026] See also Figure 5 , and also includes a hinge block 14 and a protective plate 15. The protective plates 15 are provided on the front and rear sides of the shell 3 through the hinge block 14, which are used to close the shell 3 and isolate the environment inside and outside the device to ensure the stability of production conditions. The protective plate 15 adopts a transparent structure design as a whole, which is convenient for operators to observe the working status inside the device.
