Description

Technical Field

[0001] This utility model relates to the technical field of heat-sealing packaging mechanisms, specifically to a heat-sealing packaging mechanism for blister packs. Background Technology

[0002] A search revealed Chinese patent application CN201120431779.4, which discloses a heat sealing machine. The machine includes a frame, a base, and a worktable. The worktable is placed on the base, and a cylinder is installed below it. A vertical cylinder is mounted on the frame, with a space between the vertical cylinder and the base. A heating plate is placed within this space, and a pressing plate covers the heating plate. The upper end of the heating plate is connected to the vertical cylinder via a sliding guide post. The advantages of this invention are: the pressing plate under the heating plate ensures a smooth sealing process; the heating plate is electrically connected to a temperature control button, allowing adjustment of the sealing temperature for different plastic films, ensuring a tight seal, preventing deformation of the plastic film bag, and resulting in high quality.

[0003] However, the above solution still has its drawbacks. In the process of heat sealing the plastic film, the plastic film needs to be placed on the workbench, then heat sealed, and then the heat-sealed plastic film is removed and the plastic film to be heat-sealed is placed on the workbench. This process is repeated, but it is time-consuming and labor-intensive, poses safety hazards, reduces the heat sealing efficiency of the plastic film, and brings a bad user experience.

It also includes a controller 130, which is fixed on the outer wall of the frame 120 and is set to control the electrical components.

[0030] The heat-sealing structure 140 is mounted on the frame 120. The heat-sealing structure 140 is used to heat-seal the blister packaging shell containing ECG electrode patches. The heat-sealing structure 140 includes a hydraulic cylinder 141, a connecting plate 142, an electric heating plate 143, and a pressing plate 144. The hydraulic cylinder 141 is fixed on the upper surface of the frame 120. The piston rod end of the hydraulic cylinder 141 is fixed on the upper surface of the connecting plate 142. The electric heating plate 143 is fixed on the lower surface of the connecting plate 142. The pressing plate 144 is fixed on the lower surface of the electric heating plate 143.

[0031] A transverse mechanism 160 is mounted on the upper surface of the base 110. The transverse mechanism 160 is configured to move different molds 191 directly below the pressure plate 144. The transverse mechanism 160 includes a vertical plate 161, a motor 162, a lead screw 163, a guide rod 164, and a first transverse block 165. The vertical plate 161 is fixed on the upper surface of the base 110. One end of the lead screw 163 is rotatably mounted on the outer wall of one of the vertical plates 161. The motor 162 is fixed on the outer wall of the other vertical plate 161. The other end of the lead screw 163 is fixed together with the output shaft of the motor 162. The guide rod 164 is fixed between the two vertical plates 161. The first transverse block 165 is threaded onto the lead screw 163 and is also slidably mounted onto the guide rod 164.

[0032] The locking mechanism 193 is installed on the outer wall of the first horizontal block 165. The locking mechanism 193 is used to restrict a plurality of molds 191 on the first horizontal block 165. The locking mechanism 193 includes a second horizontal block 1931, a spring 1932, a slide rod 1933 and a stop block 1934. The second horizontal block 1931 is fixed on the outer wall of the first horizontal block 165. The slide rod 1933 slides through the second horizontal block 1931. The lower end of the spring 1932 is fixed on the upper surface of the second horizontal block 1931. The upper end of the spring 1932 is fixed on the lower surface of the stop block 1934. The slide rod 1933 passes through the spring 1932. The upper end of the slide rod 1933 is fixed on the lower surface of the stop block 1934.

[0033] The working principle and process of this utility model are as follows: In use, select the corresponding mold 191 according to the model of the blister packaging shell for the ECG electrode patch. Then, press down the stop block 1934 to offset it from the slide rail 180. Next, insert the mold 191 into the slide rail 180. After installing multiple molds 191, release the stop block 1934. Under the reaction of the spring 1932 and the action of the baffle 190, the stop block 1934 moves upward, restricting the mold 191 within its designated position. On the first horizontal block 165, the blister pack containing the ECG electrode patch is then manually placed into the mold 191, with the operator and the pressing plate 144 operating separately. Then, the hydraulic cylinder 141, photoelectric switch 150, electric heating plate 143, and motor 162 are activated. The photoelectric switch 150 detects whether there is a blister pack inside the mold 191. The piston rod of the hydraulic cylinder 141 extends, causing the pressing plate 144 to move downwards and press against the blister pack. The electric heating plate 143 and the pressing plate 144 work together... Under the action of the mechanism, the blister packaging shell is heat-sealed. Then, the motor 162 works, and the rotation of the output shaft of the motor 162 drives the lead screw 163 to rotate. The first horizontal block 165 moves a specified distance under the action of the lead screw 163 and the guide rod 164, thereby removing the heat-sealed blister packaging shell. After that, the heat-sealed blister packaging shell is manually removed and a blister packaging shell to be heat-sealed is placed in it. The photoelectric switch 150 detects whether there is a blister packaging shell in the mold 191 to prevent the occurrence of air pressure. This blister packaging heat-sealing mechanism can place multiple blister packaging shells in different molds 191 at one time. Removing the heat-sealed blister packaging shell does not hinder the heat-sealing of other blister packaging shells, saving time and effort and improving heat-sealing efficiency. Moreover, the blister packaging shells are staggered from the pressure plate 144 when being picked up and placed, eliminating safety hazards. In addition, the locking mechanism 193 facilitates the quick replacement of the mold 191 according to the model of the ECG electrode patch, which is highly applicable and brings a better user experience.

[0034] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
