[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Please refer to Figure 1 - Figure 9 , a fixing device for a heat-sealing mold of a medical blister box, including a main body 1 of a heat-sealing machine, a lower mold 2, and a cover material 7. A placement groove 3 is opened at the upper end of the lower mold 2. Above the placement groove 3, there is a support member 4 for supporting the blister box. At the upper end of the lower mold 2, there is a winding assembly 5 for winding the cover material 7 and a fixing component 6 for pressing one end of the cover material 7. The support member 4 includes a support frame 43 movably connected to the upper end of the lower mold 2. The support frame 43 is used to support the edge part of the blister box. An upper mold is provided inside the main body 1 of the heat-sealing machine, and the upper mold matches the support frame 43.

[0027] In this embodiment, the support member 4 includes a number of sets of first sliding cylinders 41 fixedly connected to the lower mold 2. A first support rod 42 is slidably connected to the inside of the first sliding cylinder 41. The lower end of the first support rod 42 is fixedly connected to a first spring 44. The upper end of the first support rod 42 is fixedly connected to the support frame 43. The first spring 44 is located inside the first sliding cylinder 41. The first sliding cylinders 41 are evenly distributed around the placement groove 3.

[0028] Specifically, the support frame 43 can support the edge of the plastic - blister box, and the first spring 44 can push the first support rod 42 upward, facilitating the removal of the plastic - blister box.

[0029] In this embodiment, the winding component 5 includes a hidden groove 51 formed in the upper end of the lower mold 2. A protective cover 52 is provided at the upper end of the hidden groove 51. A partition 53 is fixedly connected to the inside of the hidden groove 51. A connecting shaft 54 is rotatably connected to the inside of the partition 53. One end of the cover material 7 is wound around the outside of the connecting shaft 54.

[0030] Specifically, the connecting shaft 54 can facilitate the winding of the cover material 7 and the hiding of the cover material 7.

[0031] In this embodiment, elastic pieces 55 are provided on the outside of the connecting shaft 54. The elastic pieces 55 are located in front of the partition 53. One end of the elastic piece 55 is fixedly connected to the partition 53, and the other end of the elastic piece 55 is fixedly connected to the connecting shaft 54.

[0032] Specifically, the elastic pieces 55 can drive the connecting shaft 54 to rotate, so that the cover material 7 can be tightened to prevent the cover material 7 from becoming loose.

[0033] In this embodiment, a baffle 56 is fixedly connected to the front end of the protective cover 52, and a cutting edge is provided at the upper end of the baffle 56.

[0034] Specifically, when the cover material 7 moves downward, the cutting edge at the upper end of the baffle 56 cuts off the cover material 7, facilitating the removal of the heat - sealed plastic - blister box.

[0035] In this embodiment, two sets of second sliding cylinders 57 are fixedly connected to the inside of the hidden groove 51. A second support rod 58 is slidably connected to the inside of the second sliding cylinder 57. The upper ends of the two sets of second support rods 58 are commonly fixedly connected to a fixed shaft 59. A rotating cylinder 511 is rotatably connected to the outside of the fixed shaft 59.

[0036] Specifically, the rotating cylinder 511 can facilitate the removal of the cover material 7 from the inside of the protective cover 52.

[0037] In this embodiment, the lower end of the second support rod 58 is fixedly connected to a second spring 510. The second spring 510 is located inside the second sliding cylinder 57, and the lower end of the second spring 510 is fixedly connected to the bottom end of the inner wall of the second sliding cylinder 57.

[0038] Specifically, the second spring 510 can be used to push the second support rod 58 upward, so that the fixed shaft 59 drives the rotating cylinder 511 to press the cover material 7 against the upper end of the inner wall of the protective cover 52, preventing the cover material 7 from being wound inside the protective cover 52.

[0039] In this embodiment, the fixing assembly 6 includes a support seat 61 fixedly connected to the upper end of the lower mold 2. A pressure plate 62 is rotatably connected to the upper end of the support seat 61. A pressure block 65 is movably connected to the rear end of the pressure plate 62. A rotating seat 63 is fixedly connected to the front end of the support seat 61. The rotating seat 63 is U-shaped. A connecting block 64 is rotatably connected to the inside of the rotating seat 63. The connecting block 64 is L-shaped. One end of the connecting block 64 is fixedly connected to the pressure plate 62.

[0040] Specifically, the pressure plate 62 can be used to press the cover material 7 against the upper end of the support seat 61, facilitating the fixing of the cover material 7.

[0041] In this embodiment, two groups of sliding grooves 66 are formed in the rear end of the pressure plate 62. A top shaft 67 is slidably connected to the inside of the sliding grooves 66. The top shaft 67 is fixedly connected to the pressure block 65. A elastic cord 68 is fixedly connected to the front end of the top shaft 67. The front end of the elastic cord 68 is fixedly connected to the inside of the sliding grooves 66.

[0042] Specifically, the elastic cord 68 can be used to pull the top shaft 67 to make the pressure block 65 closely attached to the rear end of the support seat 61, pressing the cover material 7 tightly.

[0043] It should be noted that during use, the plastic suction box is placed inside the placement groove 3, and the edge part of the plastic suction box is placed on the support frame 43. Then, the cover material 7 is pulled to cover the upper end of the plastic suction box, with one end of the cover material 7 placed on the upper end of the support seat 61. Then, the pressure plate 62 is rotated to press on the upper end of the cover material 7, making the pressure block 65 closely attached to the rear end of the support seat 61 to tightly press the cover material 7. Then, the lower mold 2 is pushed into the inside of the heat-sealing machine main body 1. The upper mold is used to heat-seal the cover material 7 and the plastic suction box. The upper mold will press the support frame 43 downward, causing the first support rod 42 to slide into the inside of the first sliding cylinder 41, making the cover material 7 move downward. The cover material 7 is cut by the edge of the upper end of the baffle 56. After the pressing and combining are completed, the second spring 510 can be used to push the second support rod 58 upward, so that the fixed shaft 59 drives the rotating cylinder 511 to press the cover material 7 against the upper end of the inner wall of the protective cover 52, preventing the cover material 7 from being wound inside the protective cover 52. The elastic sheet 55 can drive the connecting shaft 54 to rotate, making the cover material 7 taut and preventing the cover material 7 from becoming loose.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
