In this embodiment, the lower end of the push rod 1 is correspondingly provided with a first through hole and a second through hole, the first through hole is sleeved on the first chain pin 34, and the second through hole is sleeved on the second chain pin 35. So set up, push rod 1 all the time with second chain 32 synchronous motion, and push rod 1 position lock is dead, can not take place relative rotation with second chain 32.

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

In this embodiment, the connecting position between the push rod 1 and the rear stabilizer bar 33 is rounded.

In this embodiment, as shown in fig. 4, the sealing glue storage device includes a tank 43 and a tank cover 44, an opening communicated with the inside of the tank 43 is disposed at the top end of the tank 43, glue is injected into the tank 43 through the opening during specific use, the tank cover 44 is disposed at the top end of the tank 43 to seal the opening, two third screws 45 are symmetrically disposed at two sides of the tank 43, one end of each third screw 45 is rotatably connected to the tank 43, two slots 46 are symmetrically disposed at two sides of the tank cover 44, the two slots 46 correspond to the two third screws 45 one by one, and one screw is clamped in one slot 46 and fastened by one second nut 47.

It should be noted that the glue gun is not limited to the above structure, and any glue gun capable of spraying fast dry glue may be used. In addition, the glue gun needs to be cleaned regularly during specific use to prevent the glue gun from clogging.

Example two:

as shown in fig. 2-3, the difference between the automatic box sealing machine for quick-drying glue provided in this embodiment and the automatic box sealing machine for quick-drying glue provided in the first embodiment is that the holding device for automatic box sealing machine for quick-drying glue provided in this embodiment further includes a supporting plate 42, a third through hole is formed at the lower end of the push rod 1, the third through hole is sleeved on the second chain pin 35 instead of the second through hole, a recess 37 is formed at the bottom end of the front supporting rod 2, the first chain pin 34 is disposed in the recess 37, the weight of the rear stabilizing rod 33 is greater than that of the front supporting rod 2, the supporting plate 42 is disposed along the conveying direction of the packaging box 4, the supporting plate 42 is used for supporting the rear stabilizing rod 33 and assisting the rear stabilizing rod 33 to turn over, when the front supporting 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 supporting plate 42, and the front supporting rod 2 is located above the first chain pin 34. When the front and rear pins 2 and 33 move in the conveying direction of the package 4, the rear pin 33 is supported on the support plate 42, and the front pin 2 is positioned above the first chain pin 34 and supported on the first chain pin 34. With the arrangement, 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 along with the movement state of the second chain 32. Compared with the dead locking of the position of the push rod 1, the device has greatly improved flexibility.

Because the packing carton 4 that the box was accomplished still need carry out subsequent processing procedure, so need arrange the follow-up conveyor of packing carton with packing carton direction of delivery butt joint near first semicircle section 39, and then lead to near first semicircle section 39 space little, push rod 1 position does not have the purpose of locking dead in this embodiment just in order to make push rod 1, preceding die-pin 2 and back stabilizer bar 33 can conveniently pass through this first semicircle section 39. When through first half 39 circular arc sections, back stabilizer bar 33 hides inside the device, and preceding die-pin 2, back stabilizer bar 33 and push rod 1 can conveniently pass through first half circular arc sections 39, and have effectively avoided preceding die-pin, back stabilizer bar 33 and push rod 1 and the follow-up conveyor of packing carton or other spare parts to produce the collision.

In this embodiment, in order to make the package 4 be conveyed smoothly, the bottom end of the rear stabilizing rod 33 is flush with the bottom end of the push rod 1, so as to be arranged, and when the package 4 is conveyed, the rear stabilizing rod 33 is horizontally supported on the supporting plate 42.

In the specific use process of the conveying device for the packing boxes 4 provided by this embodiment, as shown in fig. 3, the second chain pin 35 serves as a fulcrum of the front supporting 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 with the supporting plate 42, the front supporting rod 2 is lapped on the first chain pin 34, the packing boxes 4 are supported on the front supporting rod 2, and the weight of the packing boxes 4 is negligible compared with the weight of the front supporting rod 2 and the rear stabilizing rod 33; 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 supporting plate 42, the rear stabilizing rod 33 and the front supporting rod 2 rotate around the supporting point under the combined action of gravity, the groove 37 and the first chain pin 34, and the position is automatically adjusted; when the second chain 32 moves to the position where the second semicircular arc section 41 is connected with the first horizontal section 38, the rear stabilizing rod 33 abuts against the supporting plate 42, and the supporting plate 42 pushes the rear stabilizing rod 33 to rotate until the rear stabilizing rod is horizontally supported on the supporting plate 42.
