Description

Technical Field

[0002] After the items are placed inside the packaging box, the end caps of the packaging box need to be glued and fixed. The manual glue dispensing workload is large. In order to reduce the manual workload, the packaging box sealing machine came into being. The packaging box sealing machine can replace the manual glue dispensing and the end cap pressing operation after the glue dispensing is completed, but the existing packaging box sealing machine still has the following defects:

[0003] 1. Existing packaging box sealing machines can only complete hot melt adhesive sealing. The adhesive performance of hot melt adhesive deteriorates or even disappears when heated. Some buyers, especially blind box buyers, take advantage of this feature to open the end cover by heating without damage to determine whether the product in the blind box is the one they want to buy. If not, they fix it with hot melt adhesive and then return it to the merchant, causing huge losses to the merchant;

[0004] 2. When the existing carton sealing machine conveys the box, the weight of the box is applied to the slide rail, the box and the slide rail slide relative to each other, and the opposing surfaces of the box and the slide rail continuously rub against each other, causing the box to often suffer varying degrees of friction damage during the conveying process.

[0049] In this embodiment, in order to extend the service life of the device, the push rod 1, the front support rod 2 and the rear stabilizing rod 33 are all made of metal.

[0050] In this embodiment, the intersection of the push rod 1 and the rear stabilizer bar 33 is rounded.

[0051] In this embodiment, if Figure 4 As shown, the sealed glue storage device includes a tank body 43 and a tank cover 44. The top of the tank body 43 is provided with an opening connected to the inside of the tank body 43. During specific use, glue is injected into the inside of the tank body 43 through the opening. The tank cover 44 is arranged at the top of the tank body 43 to seal the opening.

[0053] Embodiment 2:

[0054] like Figure 2-Figure 3 As shown, the quick-drying glue automatic box sealing machine provided by the present embodiment is different from the quick-drying glue automatic box sealing machine provided by the first embodiment in that the quick-drying glue automatic box sealing machine holding device provided by the present embodiment also includes a support plate 42, a third through hole is opened at the lower end of the push rod 1, the third through hole replaces the second through hole and is sleeved on the second chain pin 35, the bottom end of the front support rod 2 is recessed to form a groove 37, the first chain pin 34 is arranged in the groove 37, the weight of the rear stabilizing rod 33 is greater than the weight of the front support rod 2, the support plate 42 is arranged along the conveying direction of the packaging box 4, the support plate 42 is used to support the rear stabilizing rod 33 and assist the rear stabilizing rod 33 to flip, when the front support rod 2 and the rear stabilizing rod 33 move along the conveying direction of the packaging box 4, the rear stabilizing rod 33 is supported on the support plate 42, and the front support rod 2 is located above the first chain pin 34. When the front support rod 2 and the rear stabilizer rod 33 move along the conveying direction of the packaging box 4, the rear stabilizer rod 33 is supported on the support plate 42, and the front support rod 2 is located above the first chain pin 34 and supported on the first chain pin 34. In this way, the push rod 1 always moves synchronously with the second chain 32, but the position of the push rod 1 is not locked, and changes with the movement state of the second chain 32. Compared with the position of the push rod 1 being locked, the flexibility of the device is greatly improved.

[0055] Since the sealed packaging box 4 still needs to undergo subsequent processing steps, a subsequent packaging box conveying device that is connected to the packaging box conveying direction needs to be arranged near the first semicircular arc section 39, which results in a small space near the first semicircular arc section 39. The purpose of not locking the push rod 1 in this embodiment is to enable the push rod 1, the front support rod 2 and the rear stabilizing rod 33 to pass through the first semicircular arc section 39 conveniently. When passing through the first semicircular arc section 39, the rear stabilizing rod 33 is hidden inside the device, and the front support rod 2, the rear stabilizing rod 33 and the push rod 1 can pass through the first semicircular arc section 39 conveniently, and effectively avoid the front support rod, the rear stabilizing rod 33 and the push rod 1 from colliding with the subsequent packaging box conveying device or other components.

[0056] In this embodiment, in order to ensure smooth transportation of the packaging box 4 , the bottom end of the rear stabilizing rod 33 is flush with the bottom end of the push rod 1 . With this arrangement, when the packaging box 4 is transported, the rear stabilizing rod 33 is horizontally supported on the support plate 42 .

[0057] In the specific use process of the packaging box 4 conveying device provided in this embodiment, as shown in FIG. Figure 3 As shown, the second chain pin 35 acts as a fulcrum for the front support rod 2 and the rear stabilizing rod 33. When the second chain 32 moves to the first horizontal section 38, the rear stabilizing rod 33 sinks to contact the support plate 42, the front support rod 2 is placed on the first chain pin 34, and the packaging box 4 is supported on the front support rod 2. Compared with the weight of the front support rod 2 and the rear stabilizing rod 33, the weight of the packaging box 4 can be ignored; when the second chain 32 moves to the first semicircular arc section 39, the second horizontal section 40 and the second semicircular arc section 41, the rear stabilizing rod 33 is separated from the support plate 42, and the rear stabilizing rod 33 and the front support rod 2 rotate around the fulcrum under the combined action of gravity, the groove 37 and the first chain pin 34, and automatically adjust their positions; when the second chain 32 moves to the intersection of the second semicircular arc section 41 and the first horizontal section 38, the rear stabilizing rod 33 is against the support plate 42, and the support plate 42 pushes the rear stabilizing rod 33 to rotate until it is horizontally supported on the support plate 42.
