This automatic switching mechanism 100 can improve the efficiency of automatic sealing of refrigerator cartons and simultaneously enable automatic switching between tape supply mechanisms.

[0037] like Figure 1 and Figure 2As shown in this embodiment of the present invention, the automatic sealing tape supply automatic switching mechanism 100 for refrigerators includes: a base 110; a lateral movement component 120 mounted on the base 110; a movement frame 130 connected to the lateral movement component 120, the lateral movement component 120 driving the movement frame 130 to move laterally relative to the base 110; a first cylinder movement component 140 mounted on the movement frame 130; a first tape supply component 150 mounted on the movement frame 130 and used to supply the first tape, the first cylinder movement component 140 being connected to the first tape supply component 150 and driving the first tape supply component 150 to move up and down; and a second cylinder movement component 160 mounted on the movement frame 130. 0; Second tape supply assembly 170, which is mounted on the motion frame 130 and used to supply the second tape; Second cylinder motion assembly 160 is connected to the second tape supply assembly 170 and is used to drive the second tape supply assembly 170 to move up and down; Photoelectric switch 180, which is mounted on the base 110 and electrically connected to the lateral motion assembly 120, the first cylinder motion assembly 140 and the second motion cylinder assembly; Refrigerator automatic sealing tape supply automatic switching mechanism 100 has a tape supply position, and the photoelectric switch 180 is used to obtain the usage status of the first tape and the second tape, and control the lateral motion assembly 120, the first motion cylinder and the second motion cylinder according to the usage status of the first tape and the second tape, so that the first tape and the second tape are alternately located in the tape supply position, so as to seal the refrigerator with the first tape or the second tape.

[0038] It should be noted that the base 110 is used to mount the lateral motion assembly 120, which drives the motion frame 130 to perform lateral reciprocating motion. The first tape supply assembly 150 and the second tape supply assembly 170 are both mounted on the motion frame 130. Driven by the lateral motion assembly 120, the first tape supply assembly 150 and the second tape supply assembly 170 reciprocate relative to the base 110. The first cylinder motion assembly 140 is driven by the first tape supply assembly 150, and the second cylinder motion assembly 160 is driven by the second tape motion assembly. The lateral motion assembly 120 and the first cylinder motion assembly 140 together move the first tape supply assembly 150 to the tape supply position, and the lateral motion assembly 120 and the second cylinder motion assembly 160 together move the second tape supply assembly 170 to the tape supply position. In other words, the lateral movement component 120, the first cylinder movement component 140, and the second cylinder movement component 160 cooperate with each other. The photoelectric switch 180 is used to detect the usage status of the tape on the first tape supply component 150 and the second tape supply component 170. When the first tape on the first tape supply component 150 is in the tape supply position, the photoelectric switch 180 detects the usage status of the first tape. After the first tape is used up, the lateral movement component 120 and the second cylinder movement component 160 drive the second tape supply component 170 to move, so that the second tape on the second tape supply component 170 is in the tape supply position, and tape is supplied to the refrigerator sealing box through the second tape. Similarly, the photoelectric switch 180 detects the usage status of the second tape, and after the second tape is used up, the lateral movement component 120 and the first cylinder movement component 140 drive the first tape supply component 150 to move, so that the first tape on the first tape supply component 150 is in the tape supply position, and tape is supplied to the refrigerator sealing box through the first tape.

[0039] It should be noted that when the first tape is used up and tape is supplied via the second tape, tape can be added to the first tape supply component 150 to form a new first tape. This allows for direct switching back to the first tape supply component 150 and the first tape after the second tape is used up. This embodiment of the invention enables automatic switching between the first tape supply component 150 and the second tape supply component 170, ensuring a virtually uninterrupted supply of tape at the tape supply position, thereby guaranteeing continuous refrigerator sealing and ensuring work efficiency.

[0040] It should also be noted that the tape supply position refers to the position where tape can be applied to the refrigerator carton to seal it. It should also be noted that the automatic tape supply switching mechanism 100 for refrigerators provided in this embodiment can be used as a functional module of the automatic refrigerator sealing equipment. In this case, the automatic tape supply switching mechanism 100 is connected and fixed to the automatic refrigerator sealing equipment via its base 110.

The first guide component 142 is used to guide and limit the up and down movement of the first tape supply assembly 150. In this embodiment, there are two sets of first guide components 142, which can ensure the stability of the up and down movement of the first tape supply assembly 150.

The second guide component is used to guide and limit the up and down movement of the second tape supply assembly 170. In this embodiment, there are two sets of second guide components, which can ensure the stability of the up and down movement of the second tape supply assembly 170.
