Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a plate-type preheated aluminum-plastic blister packaging machine. Background Technology

[0002] The aluminum-plastic blister packaging machine uses an internal heating roller contact heating method, employing PVC rigid sheet and DPT aluminum foil as materials, and achieves sealed packaging through a blister pack structure. It is suitable for packaging solid items such as capsules, tablets, food, chemical products, and electronic components.

[0003] Existing aluminum-plastic blister packaging machines mostly use radiant heating or hot air circulation for preheating, which has the following drawbacks: non-contact heating leads to serious heat loss, high energy consumption, and low thermal efficiency; and the lower heating plate of traditional equipment is fixed and cannot be quickly detached from the PVC sheet when the machine stops, which poses a safety hazard.

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, this utility model discloses a plate-type preheated aluminum-plastic blister packaging machine, including a packaging machine body 1. The front of the packaging machine body 1 is provided with a PVC unwinding mechanism 2, a PTP aluminum foil unwinding mechanism 3, a forming mold 4, and a preheating mechanism 5. The forming mold 4 includes two fixed seats 401 distributed vertically on the front of the packaging machine body 1. An upper mold 402 and a lower mold 403 are provided between the two fixed seats 401. A hydraulic cylinder 404 for driving the upper mold 402 to move up and down is installed in the middle of the upper fixed seat 401, and a driving assembly 405 for driving the lower mold 403 to move up and down is provided on the lower fixed seat 401. The preheating mechanism 5 includes an upper heating plate 501 on the front of the packaging machine body 1, a lifting mounting plate 502 on the front of the packaging machine body 1, a lower heating plate 503 cooperating with the upper heating plate 501 at the top of the lifting mounting plate 502, and a connecting plate 509 rigidly connecting the bottom end of the lifting mounting plate 502 to the lower mold 402. The connecting plate 509 is connected to the lifting mounting plate 502 and the lower mold 403 by bolts or welding. Multiple heating tubes 504 are embedded inside both the upper heating plate 501 and the lower heating plate 503. A lifting cylinder 505 is installed on the lifting mounting plate 502 to drive the lower heating plate 503 up and down. The lifting mounting plate 502 has a dovetail groove 507, and the lower heating plate 503 has a dovetail block 508 that mates with the dovetail groove 507. The driving component 405 drives the lower mold 403 to move upwards. The lower mold 403, through the connecting plate 509, drives the lifting mounting plate 502 to move upwards, ensuring that the lower mold 403 and the lower heating plate 503 move synchronously, guaranteeing that the heating position always matches the molding station. The lower heating plate 503 automatically descends to its lowest point when the machine stops, driven by the lifting cylinder 505, to prevent continuous heat deformation of the PVC. The dovetail block 508 moves inside the dovetail groove 507, improving the stability of the lower heating plate 503's movement.

[0025] The multiple heating tubes 504 are evenly distributed inside the upper heating plate 501 and the lower heating plate 503, which makes the PVC sheet heat evenly and improves the preheating effect.

[0026] The drive assembly 405 includes a cam mechanism 4051 mounted on a fixed base 401. A reduction motor 4052 is mounted on the fixed base 401 to drive the cam mechanism 4051. The output shaft of the reduction motor 4052 drives the cam mechanism 4051 to work, thereby driving the lower mold 403 to move upward.

[0027] The two fixed bases 401 are provided with guide slide rods 406 at both ends, and the upper mold 402 and the lower mold 403 are provided with guide holes for the guide slide rods 406 to pass through, which improves the stability of the movement of the upper mold 402 and the lower mold 403.

[0028] The packaging machine body 1 has an adjustment assembly 6 on its front side for adjusting the upper heating plate 501. The adjustment assembly 6 includes a fixing block 601 on the front side of the packaging machine body 1. An adjusting screw 602, connected to the upper heating plate 501 via a bearing, is threaded onto the fixing block 601. A rotating wheel is located at the outer end of the adjusting screw 602. Rotating the rotating wheel causes the adjusting screw 602 to rotate. The adjusting screw 602 is threaded onto the fixing block 601, and its end is connected to the upper heating plate 501 via a bearing, allowing the upper heating plate 501 to move and thus adjust the upper heating plate's position. The distance between the upper heating plate 501 and the lower heating plate 503 can accommodate PVC sheets of different thicknesses. For PVC sheets of the same thickness, the position of the upper heating plate 501 remains unchanged. During heating, it is only necessary to raise the lower heating plate 503 so that the upper heating plate 501 and the lower heating plate 503 can cooperate to preheat the PVC sheet. Because the lower mold 403 and the lower heating plate 503 are synchronized, the position of the lower heating plate 503 is fixed. Therefore, by adjusting the height of the upper heating plate 501, it can be used to preheat PVC sheets of different thicknesses, thus improving applicability.

[0029] The packaging machine body 1 has two vertically downward guide rails 603 on its front side, and the upper heating plate 501 has a first guide slider 604 that cooperates with the guide rails 603. The first guide slider 604 moves along the guide rails 603, which improves the stability of the movement of the upper heating plate 501.

[0030] The lifting mounting plate 502 has a second guide slider 506 on its back side that cooperates with the guide slide rail 603. The second guide slider 506 moves along the guide slide rail 603, which improves the stability of the movement of the lifting mounting plate 502.

[0031] During operation, the drive assembly 405 drives the lower mold 403 to move upward. The lower mold 403, through the connecting plate 509, drives the lifting mounting plate 502 to move upward, so that the lower mold 403 and the lower heating plate 503 are synchronized and linked, ensuring that the heating position is always matched with the molding station. The lower heating plate 503 is driven by the lifting cylinder 505 to automatically descend to the lowest point when the machine stops, avoiding continuous heat deformation of PVC. The dovetail block 508 moves inside the dovetail groove 507, improving the stability of the movement of the lower heating plate 503. Through the provided upper heating plate 501 and lower heating plate 503, the PVC sheet is heated in contact with the upper heating plate 501 and lower heating plate 503 in a double-plate heating manner, achieving efficient heat conduction, reducing energy consumption, and improving efficiency. The bottom end of the lifting mounting plate 502 is rigidly connected to the lower mold 403, so that the lower heating plate 501 is rigidly linked with the molding mold 4. When the machine stops, the lower heating plate 503 is driven by the lifting cylinder 505 to quickly descend and detach from the PVC sheet, avoiding overheating problems during shutdown.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
