[0030] Combination Figures 1 to 6 As shown, the fully automatic high-speed blister machine provided by the utility model comprises a conveying unit 1 and a cutting unit 2.

[0031] Combination Figures 1 to 6 As shown, the conveying unit 1 includes a negative pressure forming element 11, a conveyor belt 12 and a negative pressure element 13, the negative pressure forming element 11 is provided with a blister groove 111, the negative pressure forming element 11 is evenly and closely distributed on the conveyor belt 12, the negative pressure element 13 is connected to the negative pressure forming element 11, and the working end of the negative pressure element 13 is connected to the blister groove 111; the cutting unit 2 includes a punching cylinder 21 and a supporting element 22, the punching cylinder 21 is provided with evenly distributed punching blades 211, the supporting element 22 is located directly below the punching cylinder 21 and the top surface contacts the conveyor belt 12, the blister forming element and the conveying element are combined by designing the conveying unit 1, and the blister packaging machine is avoided from stopping when forming blisters during operation; the cutting unit 2 is designed to perform cutting work during the operation of the conveying unit 1, and the blister packaging machine is avoided from stopping when cutting products during operation; the continuity of production actions is improved, and the stability of the blister packaging machine at high speed is enhanced.

[0032] In some embodiments, in combination Figures 1 to 4 As shown, the conveying unit 1 also includes a transition element 14. The shape of the transition element 14 is the same as that of the negative pressure forming element 11 without the blister groove 111. The transition element 14 is distributed on the conveyor belt 12 together with the negative pressure forming element 11. The transition element 14 is evenly interspersed in the negative pressure forming element 11. The addition of the transition element 14 can facilitate the operation of the cutting unit 2, increase the sealing length at the upper edge of the final product, and improve the reliability of the blister packaging.

[0033] In some embodiments, in combination Figures 1 to 6 As shown, the transition element 14 is provided with an auxiliary blade 141, and the auxiliary blade 141 can cooperate with the punching blade 211 to perform cutting. Adding the auxiliary blade 141 to cooperate with the punching blade 211 to perform cutting can effectively ensure the reliability of the cutting action and avoid the need for secondary processing due to insufficient cutting.

[0034] In some embodiments, in combination Figures 1 to 6 As shown, both the negative pressure forming element 11 and the transition element 14 are provided with a limiting structure 101. The limiting structure 101 is added to position the forming film and the covering film to avoid the blister position shifting and affecting the product quality, thereby effectively improving the reliability of the blister packaging machine.

[0035] In some embodiments, in combination Figure 1 , Figure 2 As shown, the blister packaging machine also includes a hot pressing shaft 3, which is equipped with a heat resistance wire. The hot pressing shaft 3 contacts the conveying unit 1 and is located in front of the cutting unit 2. When working, the covering film is wrapped around the hot pressing shaft 3, and the hot pressing shaft 3 completes the sealing work of the forming film and the covering film.

[0036] In some embodiments, in combination Figure 1 , Figure 2 As shown, the hot pressing shaft 3 is also equipped with a spring 31, and the spring 31 is arranged in a direction perpendicular to the conveying unit 1. The direction of the force provided by the spring 31 points to the conveying unit 1. The addition of the spring 31 can ensure the stability of the pressure of the hot pressing shaft 3 on the product, improve the sealing effect of the molding film and the covering film, and at the same time achieve adaptation for molding films and covering films of different thicknesses.

[0037] In some embodiments, in combination Figure 1 , Figure 2 As shown, the hot pressing shaft 3 is also equipped with an auxiliary shaft 32, and the auxiliary shaft 32 is arranged at a position horizontal to the hot pressing shaft 3. A limiting step 321 is also provided on the auxiliary shaft 32. The surface of the auxiliary shaft 32 has good fit with the covering film. The auxiliary shaft 32 mainly assists the work of the hot pressing shaft 3 and helps the hot pressing shaft 3 to complete the feeding of the covering film. Since the hot pressing shaft 3 heats the covering film to soften the covering film, the feeding of the covering film by the hot pressing shaft 3 alone can easily lead to problems such as the covering film being stretched. At the same time, a limiting step 321 is also provided on the auxiliary shaft 32 to position the covering film. Since the hot pressing shaft 3 needs to press the molding film and the covering film, an efficient limiting structure cannot be designed on the hot pressing shaft. By designing a limiting step on the auxiliary shaft 32, the problem of the covering film running off can be effectively avoided.

[0038] In some embodiments, in combination Figure 1 , Figure 2As shown, the blister packaging machine also includes a cold air fan 4, which is located behind the hot pressing shaft 3 and the auxiliary shaft 32, and in front of the cutting unit 2, and the air outlet of the cold air fan 4 is close to the conveying unit 1. The cold air fan 4 can fully cool the forming film and the covering film that have been sealed by the hot pressing shaft 3, so as to avoid the uncooled forming film and the covering film from sticking to the knife when the punching cylinder 21 is cutting, thereby affecting the cutting work.

[0039] In some embodiments, in combination Figure 1 , Figure 2 As shown, the blister packaging machine also includes a blanking machine 5, which is located in front of the hot pressing shaft 3. The outlet end of the blanking machine 5 is close to the conveying unit 1. The blanking machine 5 will place the packaged object into the blister in time after the conveying unit 1 completes the blister forming.

[0040] In some embodiments, in combination Figure 1 , Figure 2 As shown, the blister packaging machine further includes a heating element 6, which is located in front of the conveying unit 1 and close to the conveying unit 1. The heating element 6 heats the forming film that is about to enter the conveying unit 1 so that the conveying unit 1 can perform blister forming.

[0041] Working process: the formed film passes through the heating element 6, which heats the formed film, and then the formed film enters the conveying unit 1; then the limiting structure 101 in the conveying unit 1 will position the formed film, and after the positioning is completed, the negative pressure element 13 will be started, and cooperate with the negative pressure forming element 11 to form the blister, during which the conveyor belt 12 will drive the formed film and the negative pressure forming element to move backward; after the blister forming work is completed, it will move to the unloading machine 5, and the unloading machine 5 will put the packaged material into each blister; then it will move to the hot pressing shaft 3, and the auxiliary shaft 32 will help the hot pressing shaft 3 to feed the covering film, and then the conveyor belt 12 will move to the hot pressing shaft 3 to feed the covering film. The spring 31 provides the required pressure for the hot pressing shaft 3, and finally the hot pressing shaft 3 completes the sealing work of the forming film and the covering film; then it will move to the cold air blower 4, which will fully cool it; after the cooling work is completed, it will move to the cutting unit 2, and the punching cylinder 21 will press and position it, and the punching blade 211 and the auxiliary blade 141 on the transition element 14 inserted in the negative pressure forming element 11 will cooperate to complete the cutting work. During this period, the supporting element 22 contacts the conveyor belt 12 to ensure that the conveyor belt 12 will not be deformed by force and affect the cutting effect during the cutting work. Then the products that have completed cutting will move out of the blister packaging machine.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
