[0040] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0041] Example:

[0042] The accompanying drawings show a specific implementation of a white vinegar box sealing detection system of the utility model. Figure 1 It mainly includes a high-level conveyor line 1 and a low-level conveyor line 2. A sealing mechanism 3 is provided above the output end of the high-level conveyor line 1. The packaging box a is sent from the high-level conveyor line 1 to the sealing mechanism 3 for sealing and then automatically falls onto the low-level conveyor line 2. The 90-degree overturning action is completed through the height difference between the high and low-level conveyor lines to detect whether the seal is sealed.

[0043] Combination Figure 2 The sealing mechanism 3 specifically includes a mounting base 4, on which are disposed a tape supply mechanism 5, a pressure-sealing mechanism 6 and a tape cutting mechanism 7. The tape supply mechanism 5 is used to provide tape b, the pressure-sealing mechanism 6 is used to adhere the tape b to the packaging box a for sealing, and the tape cutting mechanism 7 is used to cut the tape b. The three mechanisms are compact in structure, clearly laid out, and well coordinated with each other, and can complete the sealing action in one go.

[0044] Among them, the tape supply mechanism 5 includes a tape roll 51 arranged on the top of the mounting base 4, a first guide roller 52 and a second guide roller 53 arranged on the upper part of the mounting base 4, and the tape b of the tape roll 51 is passed through the first guide roller 52 and the second guide roller 53 and then inserted into the tape threading mechanism 63.

[0045] The sealing mechanism 6 comprises a front rotating arm 61 and a rear rotating arm 62 connected by a linkage mechanism, and the bottom ends of the front rotating arm 61 and the rear rotating arm 62 are rotatably mounted with a front pressure roller 61a and a rear pressure roller 62a, respectively, and the belt threading mechanism 63 is fixedly mounted at the lower part of the front rotating arm 61 near the front pressure roller 61a. In this embodiment, the linkage mechanism comprises a linkage frame 64 arranged in the middle of the mounting base 4, and the linkage frame 64 specifically comprises an upper end seat and a lower end seat connected by a vertical rod, and a sliding sleeve 66 is slidably mounted on the vertical rod, and the two ends of the sliding sleeve 66 are penetrated by the vertical rod, and a receiving cavity is opened at the bottom of the sliding sleeve 66, and a spring 65 is installed in the receiving cavity, and the spring 65 is sleeved on the vertical rod, and the other end of the spring 65 is against the lower end seat, and the spring 65 provides an upward force for the sliding sleeve 66 to push the sliding sleeve 66 against the upper end seat. Both sides of the sliding sleeve 66 are rotatably connected with an articulated link 67 through an articulated seat 66a, and the other end of the articulated link 67 is rotatably connected to the front rotating arm 61 or the rear rotating arm 62. The front rotating arm 61 and the rear rotating arm 62 are rotatably installed on the lower part of the mounting base 4 through a rotating pin 68.

[0046] The tape b provided by the tape supply mechanism 5 is inserted into the tape threading mechanism 63. Through the cooperation of the linkage mechanism, the front rotating arm 61 and the rear rotating arm 62 can cooperate with each other to use the front pressure roller 61a and the rear pressure roller 62a to pull the tape b from one side of the packaging box a along the middle position of the top two side box covers to the other side of the packaging box a for sealing.

[0047] In this embodiment, the pulling action of the adhesive tape is coordinated with the tape threading mechanism 63. The specific structure of the tape threading mechanism 63 is as follows: Figure 3As shown, it mainly includes a tape-threading seat 631 fixedly mounted on the front rotating arm 61, a tape-threading head 632 is provided on the tape-threading seat 631, a tape-threading channel 633 is provided in the tape-threading head 632, and the adhesive tape b is passed through the tape-threading channel 633 from one end of the tape-threading head 632 and then passed out from the other end of the tape-threading head 632. The tape-threading head 632 is composed of two parts, including a suction head 632a and a guide head 632b connected and matched, the suction head 632a is connected to a negative pressure generator 634, a sponge 635 is provided in the suction head 632a, and the sponge 635 is located at one side of the tape-threading channel 633. The suction force generated by the negative pressure generator 634 is uniformly applied through the sponge 635 and acts on the adhesive tape b, and negative pressure suction can be performed when not in use to ensure the continuous use of the adhesive tape b next time.

[0048] In this embodiment, a detection sensor 8 is also provided on one side of the front pressure roller 61a. The detection sensor 8 is connected to the bottom of the mounting base 4 through a connecting bracket 9. The specific installation position of the detection sensor 8 can be combined with Figure 5 The negative pressure generator 634 of the tape threading mechanism 63 is turned on or off by the detection signal of the detection sensor 8. When the detection sensor 8 detects the signal of the front pressure roller 61a, it indicates that the tape is not in use, and the negative pressure generator 634 performs negative pressure adsorption on the tape b. On the contrary, when the detection sensor 8 does not detect the signal of the front pressure roller 61a, it indicates that the tape is in use, and the negative pressure generator 634 does not perform adsorption.

[0049] In this embodiment, the height of the front pressure roller 61a is lower than that of the rear pressure roller 62a, and when the rear pressure roller 62a presses the tape b to seal the lid of the packaging box a, the height of the linked front pressure roller 61a is higher than that of the rear pressure roller 62a so that the tape b can be lifted to a certain height, the sealing action is smoother, and the tape is easier to cut.

[0050] Further, such as Figure 2The tape cutting mechanism 7 includes a follower frame 71 disposed between the front rotating arm 61 and the rear rotating arm 62. The follower frame 71 is mounted on the connecting frame through a torsion spring. The connecting frame is connected to the mounting base frame 4. The follower frame 71 can be reset by the torsion spring. The follower frame 71 is provided with a side pressure knife 72 and an intermediate cutter 73. The side pressure knife 72 is used to rotate and press the box cover when the packaging box a is sealed, and the intermediate cutter 73 is used to cut the tape b. Specifically, the intermediate cutter 73 is slidably mounted on the follower frame 71. One side of the follower frame 71 is provided with a telescopic cylinder 74 that is connected to drive the intermediate cutter 73 to extend and retract. The telescopic cylinder 74 is not shown in the figure. The side pressure knife 72 is also provided with a height sensor for detecting the height. The telescopic cylinder 74 controls the extension or retraction of the intermediate cutter 73 through the detection signal of the height sensor. When the height sensor detects that the side pressure knife 72 starts to fall from the highest point, it indicates that the tape required for sealing the box has been completely pulled out. At this time, the telescopic cylinder 74 drives the middle cutter 73 to extend, and the tape is quickly cut off in coordination with the falling action to avoid the situation where the tape cannot be cut. When the height sensor detects that the side pressure knife 72 falls back to the lowest point, it indicates that the cutting action is completed, and the middle cutter 73 is retracted to wait for the next tape cutting.

[0051] When the white vinegar box sealing detection system of this embodiment is working, the initial state is as follows Figure 1 As shown, the packaging box a is sent from the high-level conveyor line 1 to the sealing mechanism 3 for sealing. The front pressure roller 61a first contacts the packaging box a and sticks one end of the tape b to one side of the packaging box a. As the packaging box a moves, the tape b is continuously pulled out, and the tape roll 51 automatically releases the tape b, which is then sealed along the middle position of the top two side box covers through the front pressure roller 61a. Figure 4 As shown, at this time, the side pressing blade 72 contacts with the packaging box a and rotates to press the box cover. As the packaging box a continues to move, the rear pressing roller 62a contacts with the packaging box a and rises, pressing the adhesive tape b to further seal it. At this time, the front pressing roller 61a is lifted to a certain height, so that the end of the adhesive tape b is lifted to a certain height, as shown in FIG. Figure 5 Then, as the adhesive tape b is continuously pulled to the other side of the packaging box a, the side pressure knife 72 slides to separate from the packaging box a, and falls down and resets under the action of the torsion spring. The height sensor detects that the side pressure knife 72 starts to fall from the highest point, and at the same time, the telescopic cylinder 74 drives the middle cutter 73 to extend, and the adhesive tape b can be quickly cut off in coordination with the falling action, as shown in FIG. Figure 6 The other end of the cut tape b is continued to be adhered to the other side of the packaging box a through the rear pressure roller 62a to complete the sealing. When the side pressure knife 72 falls back to the lowest point, the middle cutter 73 is retracted to wait for the next tape cutting. Figure 7As shown, at this time, the front pressure roller 61a and the rear pressure roller 62a are linked. As the front pressure roller 61a falls back, the tape b slides a distance in the tape threading mechanism 63. When the detection sensor 8 detects the reset signal of the front pressure roller 61a, the negative pressure generator 634 of the tape threading mechanism 63 applies negative pressure to the tape b to ensure the continuous use of the tape next time. Finally, the packaged box a will automatically fall onto the low-level conveyor line 2, as shown in FIG. Figure 8 As shown, by completing a 90-degree tipping action through the height difference of the high and low conveyor lines, it is possible to detect whether the seal is sealed. If the seal is unqualified, the seal will be opened, and workers can find unsealed products in time, thereby improving the qualified rate of product packaging.

[0052] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical solution of the utility model should be included in the protection scope of the utility model.
