Abstract
Description
Technical Field
[0001] The utility model relates to packaging equipment, in particular to a heat sealing mechanism of a blister packaging machine. Background Art
[0002] Blister packaging machine is a common packaging equipment. During the packaging process, after the material is placed on the blister substrate, the blister substrate and the aluminum-plastic film need to be heat-sealed to seal the material. The traditional heat-sealing mechanism controls the upper and lower heat-sealing plates to contact each other during the heat-sealing process, and then heat-seals the passing blister substrate and the aluminum-plastic film. In particular, for an aluminum-plastic-aluminum blister package, during the actual processing, when the rolls of various substrates are changed or the equipment needs to be stopped for various reasons such as inspection, the heat-sealed packaging substrate will also stop pulling, and the lower heat-sealing plate may also be in a stopped state. If the packaging substrate is in contact with the lower heat-sealing plate for too long, it is easy to cause the packaging substrate to deform, affecting the stability of the packaging substrate shape and the heat-sealing processing quality.

[0013] The utility model has the following drawings:
[0014] Figure 1 It is a schematic diagram of the structure of the utility model;
[0015] Figure 2 for Figure 1 Another view with part of the casing removed. DETAILED DESCRIPTION
[0016] As shown in the figure, the heat sealing mechanism of the blister packaging machine disclosed in the utility model includes an upper lifting seat 6 and a lower lifting seat 12. Specifically, the upper lifting seat 6 is connected to the piston rod of the first cylinder 5, the cylinder body of the first cylinder 5 is arranged on the frame, the bottom of the lower lifting seat 12 is against the driving cam 17, the bottom of the lower lifting seat 12 is provided with a roller 16 pressed tightly against the driving cam 17, the driving cam 17 is connected to the driving shaft 15, and the driving shaft 15 is connected to the output end of the first motor. The upper lifting seat 6 is installed with an upper heat sealing plate 8 and an upper heating plate 7, the lower lifting seat 12 is installed with a lower heat sealing plate 10 and a lower heating plate 11, and a movable heat insulation plate 3 is arranged on one side of the lower lifting seat 12, and the heat insulation plate 3 is connected to the mobile driving assembly. In this embodiment, the mobile driving assembly includes a rodless cylinder, and the moving block 1 of the rodless cylinder is connected to the heat insulation plate 3. The heat insulation board 3 can extend between the upper heat sealing board 8 and the lower heat sealing board 10, and quickly separate the heat-sealed packaging substrate from the lower heat sealing board 10. Furthermore, a water-cooling channel is provided in the heat insulation board 3, one end of which is connected to the water inlet pipe 13 and the other end is connected to the water outlet pipe 14, so that the heat insulation board 3 can maintain a low temperature state, thereby absorbing the heat of the film material after the heat sealing is completed, realizing rapid cooling of the film material, and ensuring the stability of its shape; in addition, the heat insulation board 3 is located on the feeding end side of the lower lifting seat 12, which makes it easier for the heat insulation board 3 to separate the heat-sealed film material from the lower heat sealing board. The heat insulation board 3 is provided with convex strips 4 corresponding to the position of the groove 9 on the lower heat sealing board 10, and the convex strips 4 can contact the part of the blister substrate that has not been hot-pressed by the groove 9, so as to avoid the depression on the blister substrate that has been hot-pressed by the groove 9 being squeezed by the heat insulation board 3 and deformed.
[0017] The working principle of the utility model is as follows: the blister substrate with the material placed thereon is pulled between the upper and lower heat-sealing plates together with the aluminum-plastic film, and then the upper and lower lifting seats are close to each other, so that the upper and lower heat-sealing plates squeeze the blister substrate and the aluminum-plastic film together for heat sealing. When the heat sealing is completed, the upper lifting seat 6 rises rapidly to separate the upper heat-sealing plate 8 from the substrate, and at this time the heat insulation plate extends between the upper and lower heat-sealing plates, and drives the substrate to move upward, so that the substrate is quickly separated from the lower heat-sealing plate 10. After waiting for the substrate to be pulled, the heat insulation plate 3 moves back and resets to perform the next heat-sealing operation.
[0018] The structure of the utility model, by additionally providing a heat insulation plate 3, can control the heat insulation plate 3 to extend between the upper and lower heat sealing plates when the heat sealing process is completed or the machine is shut down, and drive the packaging substrate to quickly separate from the lower heat sealing plate, thereby avoiding deformation of the packaging substrate caused by the contact time between the packaging substrate and the lower heat sealing plate being too long, and effectively ensuring the quality of the heat sealing process.
