Technical Field

[0001] The present invention relates to the field of packaging equipment, and more specifically, it relates to an automatic blister packaging machine and its usage method. Background Art

[0002] A blister packaging machine (also called a thermoforming machine) is a machine that sucks heated and plasticized thermoplastic plastic coils such as PVC and PE into various shapes of high-grade packaging and decoration boxes, frames and other products. Thermoforming, also known as hot plastic forming, mainly uses the vacuum suction generated by a vacuum pump to soften and heat PVC, PET, PETG, APTT, PP, PE, PS, etc.

[0003] In the existing technology, the molten plastic is directly adsorbed onto the surface of the mold by opening and closing the upper and lower molds, and then the mold is opened and cooled to form a finished product and then discharged. However, after the mold is opened and closed for a long time, the positioning of the mold is prone to deviation, resulting in the appearance of flowing edges and corners on the side of the blister product, which requires post-cutting, affecting production efficiency and the pass rate.

[0052] S2: The conveying of the conveying component is achieved by the driving motor 220 driving the central gear 230 to rotate. The rotation of the central gear 230 drives the sleeve to rotate, and at the same time pulls the tension connecting rods 240 on both sides. The tension connecting rods 240 drive the cylinders 260 and the grippers 270 on both sides to clamp and fix to the side wall of the combination template 210.

[0053] As Figure 4 shown, the central gear 230 rotates, driving the tension connecting rods 240 on both sides to rotate. At the same time, it drives the gripper 270 connected to the rod end to clamp inward, fixes the combination template 210, and subsequently drives the combination template 210 to adjust.

[0054] S3: After the clamping member clamps, the driving motor 220 continues to rotate, driving the central gear 230 to rotate. The central gear 230 is in meshing transmission connection with the rack 250, driving the entire clamping member to move along the length direction of the workbench 100. At the same time, the lifting member is used to continuously press the combination template 210 onto the blister seat 300 for combination.

[0055] S4: There are combination columns 213 between the combination template 210 and the blister seat 300. Through the positioning of the combination columns 213 on the combination template 210 and the blister seat 300, before positioning, the molten material to be blistered is placed in the cavity between the combination template 210 and the part of the detachable mold, and the part of the detachable mold is enclosed on the blister seat 300.

[0056] S5: The air pump 600 at the bottom removes the gas in the cavity between the combination template 210 and the part of the detachable mold. The air pump 600 sucks out the cavity in the cavity through the air pipe via the combination hole 830, and is sucked out through the air hole 214, so that the molten material located on the convex part 840 is attached to the outer wall of the convex structure.
