Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and specifically relates to a heat-sealing module of a packaging device. Background Art

[0002] In the domestic market, blister packaging machines used for packaging small items such as granular medicines or foods generally adopt drum-type aluminum-plastic packaging, sealing various granular medicines or foods and other small items between the blisters of non-toxic polyvinyl chloride film (PVC) and aluminum foil. This aluminum-plastic packaging has certain moisture-proof and air-proof properties, which is convenient for storage and transportation.

[0003] Tablets or solid capsules are sealed in fixed blister holes by the heat-sealing action of the upper and lower modules of the packaging device. The usual hot air method is that only the upper module has reticulated bumps and is sealed by single-sided bumps. When sealing, since the upper module has bumps and the lower module does not, when the upper and lower modules are pressed together to seal the blister and aluminum foil, the stress on the blister is uneven, and the heated blister is prone to curl under the pressing of the bumps on the upper module, affecting the sealing effect. Therefore, we propose a heat-sealing module of a packaging device. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heat-sealing module of a packaging device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A heat-sealing module of a packaging device, which relates to the technical field of packaging, includes an upper module and a lower module. A plurality of limit posts are fixed on the top of the lower module, and the upper module is slidably arranged on the limit posts. A uniformly distributed protrusion is fixed on the bottom of the upper module, and uniformly distributed grooves are arranged on the top of the lower module. The protrusions and the grooves are in one-to-one fitting correspondence. By arranging grooves on the lower module that are paired with the protrusions on the upper module, when the upper module and the lower module are heat-sealed and pressed together, the protrusions press the aluminum foil and the heat-softened blister into the grooves, reducing the stress on the blister at the protrusion position and preventing the blister from bending, thereby ensuring the sealing effect of the aluminum foil and the blister after heat-sealing.

[0006] Preferably, uniformly distributed vertical through holes are arranged inside the lower module, and the vertical through holes penetrate and communicate with the grooves. When the protrusions press the aluminum foil and the blister into the grooves, the air in the grooves enters the vertical through holes, reducing the air pressure in the grooves and ensuring the smooth sealing of the aluminum foil and the blister.

[0007] Preferably, uniformly distributed horizontal through holes are arranged inside the lower module. The horizontal through holes are located between adjacent grooves, and the horizontal through holes are communicated with the vertical through holes, increasing the movement space of the air in the grooves and further reducing the reaction force of the gas in the grooves on the blister during pressing.

[0008] Preferably, the bottoms of the horizontal through holes and the vertical through holes are flush with the inner bottom of the groove, so as to prevent the blister from blocking the connection port between the groove and the vertical through hole when being pressed halfway.

[0009] Preferably, the heights of the horizontal through holes and the vertical through holes are both smaller than the height inside the groove, ensuring that only the groove and the notch for placing the blister holes are on the top of the lower module.

[0010] Preferably, both ends of the horizontal through holes and the vertical through holes are communicated with the external environment, making the air pressure in the groove equal to the external air pressure, so that the packaging protrusion can quickly press the aluminum foil and the blister into the groove.

[0011] Preferably, openings are symmetrically arranged at the top of the lower module, and the openings are located at the four corners of the top of the lower module. The sealed blister can be removed through the openings.

[0012] Preferably, four limiting blocks are symmetrically fixed at the top of the lower module, and four limiting grooves are symmetrically arranged at the bottom of the upper module. The limiting grooves are fitted with the limiting blocks to limit the four sides of the blister placed on the lower module, thereby preventing the blister from sliding during pressing.

[0013] Compared with the traditional technology, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing grooves on the lower module that are paired with the protrusions on the upper module, when the upper module and the lower module are heat-sealed and pressed, the protrusions press the aluminum foil and the heat-softened blister into the grooves, reducing the stress on the blister at the protrusion, preventing the blister from bending, and thus ensuring the airtight sealing effect of the aluminum foil and the blister after heat sealing;

[0015] 2. By providing vertical through holes connecting each groove and horizontal through holes connecting each vertical through hole inside the lower module, when the protrusion slowly presses the aluminum foil and the heat-softened blister into the groove, the air in the groove can reach the outside along the vertical through holes and the horizontal through holes, ensuring that the air pressure in the groove is equal to the air pressure of the external environment during pressing, thereby ensuring the rapid heat-sealing of the aluminum foil and the blister.

[0022] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment:

[0024] Please refer to Figures 1 - 5 , in the figure, a heat-sealing module of a packaging device, which relates to the technical field of packaging, includes an upper module 1 and a lower module 2. A plurality of limit posts 3 are fixed on the top of the lower module 2, and the upper module 1 is slidably arranged on the limit posts 3. A uniformly distributed protrusion 4 is fixed on the bottom of the upper module 1, and uniformly distributed grooves 5 are arranged on the top of the lower module 2. The protrusion 4 and the groove 5 are in one-to-one fitting correspondence.

[0025] Next, in conjunction with the accompanying drawings, some implementation manners of the present application will be described in detail:

[0026] Please refer to Figures 1 - 5 , by providing a groove 5 on the lower module 2 that mates with the protrusion 4 on the upper module 1, when the upper module 1 and the lower module 2 are heat-sealed and pressed, the protrusion 4 presses the aluminum foil and the heat-softened blister into the groove 5, reducing the stress on the blister at the protrusion 4 and preventing the blister from bending. Furthermore, the sealing tightness between the aluminum foil and the blister after heat-sealing can be ensured. Four limit blocks 9 are symmetrically fixed on the top of the lower module 2, and four limit grooves 10 are symmetrically arranged on the bottom of the upper module 1. The limit grooves 10 are fitted with the limit blocks 9 to limit the periphery of the blister placed on the lower module 2, thereby preventing the blister from sliding during pressing.

[0027] Among them, as Figure 3 and Figure 4 shown, the lower module 2 is internally provided with uniformly distributed vertical through-holes 6, and the vertical through-holes 6 penetrate and communicate with the grooves 5. When the protrusion 4 presses the aluminum foil and the blister into the groove 5, the air in the groove 5 enters the vertical through-holes 6, reducing the air pressure in the groove 5 and ensuring the smooth sealing of the aluminum foil and the blister.

[0028] Furthermore, as Figure 3As shown in the figure, the lower module 2 is internally provided with uniformly distributed horizontal through holes 7. The horizontal through holes 7 are located between two adjacent grooves 5. The horizontal through holes 7 are communicated with the vertical through holes 6, which increases the movement space of the air in the grooves 5 and further reduces the reaction force of the gas in the grooves 5 on the blister during pressing. The heights of both the horizontal through holes 7 and the vertical through holes 6 are smaller than the height inside the grooves 5, ensuring that only the grooves 5 and the notches for placing blister holes are present at the top of the lower module 2, and preventing the appearance of slots at the top of the lower module 2 that may affect the blister pressing effect.

[0029] It should be noted that, as Figure 4 shown, the bottoms of both the horizontal through holes 7 and the vertical through holes 6 are flush with the bottom inside the grooves 5, preventing the blister from blocking the connection port between the groove 5 and the vertical through hole 6 during the middle of the pressing process. Both ends of the horizontal through holes 7 and the vertical through holes 6 are communicated with the external environment, equalizing the air pressure inside the grooves 5 with the external air pressure, and enabling the packaging protrusion 4 to quickly press the aluminum foil and the blister into the grooves 5.

[0030] Place the blister into the four limit blocks 9, put the tablets or solid capsules into the blister holes, cover the aluminum foil, and then the upper module 1 presses down. Under the action of heat sealing, the protrusion 4 at the bottom of the upper module 1 presses the aluminum foil and the softened part of the blister into the grooves 5 of the lower module 2. During the pressing process, the air in the grooves 5 is discharged to the outside through the vertical through holes 6 and the horizontal through holes 7, ensuring that the air pressure inside the grooves 5 is always equal to the external air pressure, thereby ensuring that the aluminum foil and the blister are smoothly pressed into the grooves 5 to complete heat sealing, avoiding the possible bending phenomenon of the blister during the pressing process, and ensuring the airtight effect of the final product sealing.

[0031] Please refer to Figures 2 - 4 , in this embodiment, as Figure 5 shown, the top of the lower module 2 is symmetrically provided with openings 8. The openings 8 are located at the four corners of the top of the lower module 2. The sealed blisters can be removed through the openings 8.

[0032] After the blister and the aluminum foil are heat-sealed and cooled down, hold the four corners of the blister through the openings 8, and the blister can be removed from the lower module 2. At the same time, since the pressure inside the groove 5 is equal to the external environment pressure, it can be avoided that the blister is sucked by the groove 5 when being taken out of the groove 5, thereby facilitating the removal of the blister.

[0033] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but may also include other elements not expressly listed, or elements inherent to such process, method, article or device.

[0034] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand 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.
