Description

Technical Field

[0001] The utility model relates to the technical field of blister box packaging machines, in particular to a packaging machine for blister boxes. Background Art

[0002] The blister packaging machine places the product to be packaged in a special mold. Subsequently, the open end of the blister box is covered with a pre-selected plastic sheet. Next, the packaging machine's built-in hot press system starts to apply heat and pressure to the plastic sheet, causing the edge of the sheet to melt and tightly bond with the outline edge of the blister box at high temperature, thus achieving a seamless fusion between the two, and finally forming a sealed package body, completing the packaging of the blister box.

[0003] During the hot pressing process of plastic boxes, a large amount of heat will accumulate in the edge areas of the sheet and the plastic box due to heat transfer and concentration effects. If effective heat dissipation measures are not taken in time, the accumulated heat will cause thermal stress deformation at the edge of the plastic box, thereby affecting the overall dimensional accuracy and appearance quality of the product.

[0004] In order to solve the above problems, the present application proposes a packaging machine for blister boxes. Utility Model Content

[0005] Based on the technical problems existing in the background technology, the utility model proposes a packaging machine for blister boxes.

[0007] A tubular dust blowing member for blowing air onto the surface of the mold box is installed on the inner side of the packaging machine body;

[0008] A reciprocating air supply component connected to the hot pressing plate is installed on the top side of the packaging machine body, and the tubular dust blowing component is connected to the reciprocating air supply component through an air guide pipe.

[0009] Preferably, the tubular dust blowing member includes a dust blowing pipe, which is transversely installed on the inner side of the packaging machine body and located on one side of the mold box. The dust blowing pipe is connected to a side close to the mold box with several spaced dust blowing nozzles.

[0010] Preferably, the reciprocating air supply part includes an air cylinder, which is installed on the top side of the packaging machine body. An air cavity is opened in the air cylinder, and a piston part is slidably arranged in the air cavity. The bottom end of the piston part slides through the bottom end of the air cylinder and is connected to the top of the edge of the hot pressing plate. The two ends of the air guide tube are respectively connected to the top of the air cylinder and one end of the dust blowing tube.

[0011] Preferably, the piston portion includes a piston body, which is slidably arranged in the air cavity, and a movable rod is installed at the bottom of the piston body, and the bottom end of the movable rod slides through the bottom end of the air cylinder and is connected to the top of the edge of the hot pressing plate.

[0013] The above technical solution of the utility model has the following beneficial technical effects:

[0014] By means of the provided tubular dust blowing member and the reciprocating air supply member, the blister box to be packaged can be placed in the mold box, and then the plastic sheet can be placed at the opening of the blister box. Subsequently, the blister box on the mold box can be rotated to the position below the hot pressing plate by the turntable, and the hot pressing plate can be driven to move down and press on the blister box placed in the mold box, so that the plastic sheet and the blister box are melted to complete the sealed packaging of the blister box. In the process of pressing down, the hot pressing plate can drive the reciprocating air supply member to move down, and the external cold air can enter the reciprocating air supply member along the tubular dust blowing member and the air guide pipe. After the blister box is sealed, the hot pressing plate can be driven to move up The hot pressing plate can move away from the blister box, and in the process of moving upward, it can push the reciprocating air supply part to move upward, and guide the cold air inside it to the tubular dust blowing part along the air guide pipe, and the cold air can be blown to the blister box in the mold box through the tubular dust blowing part, so as to quickly cool down the blister box. This structure can quickly cool down the edge and surrounding area of ​​the newly formed plastic box immediately after the hot pressing plate completes the melting and sealing of the plastic sheet and the blister box, thereby reducing the accumulation of heat at the edge of the plastic box, effectively preventing the deformation problem caused by thermal stress, and thus improving the dimensional accuracy and appearance quality of the product.
