[0023] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0024] like Figure 1As shown in one embodiment of this utility model, the food packaging bag spout assembly device includes a frame 1, a spout clamping mechanism 200, and at least two clamping heat-sealing mechanisms. The spout clamping mechanism 200 includes a rotation adjustment component 210, at least two spout clamping components 220, and at least two lateral pushing components 230. The mounting end of the rotation adjustment component 210 is connected to the frame 1. All the lateral pushing components 230 are connected to the rotating end of the rotation adjustment component 210. Each lateral pushing component 230 is associated with a corresponding spout clamping component.

[0025] The technical solution of this utility model adopts the rotational driving action of the rotational adjustment component, combined with the lateral pushing action of the corresponding lateral pushing component, to quickly switch between different suction nozzle clamping components, thereby improving the speed and smoothness of suction nozzle feeding; and also promotes the smooth assembly between the suction nozzle and the bag body by alternating conveying of two different clamping heat-sealing mechanisms with staggered settings; thus improving operating efficiency.

[0026] Specifically, in some implementations, such as Figure 1 and 2 As shown, the rotation adjustment component 210 includes an adjustment rotation motor 211, an adjustment rotation shaft 212, an adjustment support plate 213, and a mounting bracket 214. The adjustment rotation motor 211 is connected to the frame 1 and to one end of the adjustment rotation shaft 212. The other end of the adjustment rotation shaft 212 (via a movable bearing) is connected to the mounting bracket 214. The mounting bracket 214 is connected to the frame 1. The adjustment support plate 213 (by bonding, threading, or welding) is connected to the outer surface of the adjustment rotation shaft 212. The lateral movement pushing component 230 is connected to the adjustment support plate 213. This structure, driven by the adjustment rotation motor 211, allows different groups of suction nozzle clamping components 220 and lateral movement pushing components 230 to rotate sequentially along the XY axis for material feeding, thereby improving the speed and smoothness of suction nozzle feeding. In some embodiments, such as... Figure 2As shown, the mounting bracket 214 has at least two first connecting plates 215 on its side; each first connecting plate 215 is equipped with a detection sensor 216; the detection end of the detection sensor 216 is positioned towards the nozzle clamping component 220. Further, the detection sensor 216 can be an infrared sensor or a photoelectric sensor, etc., to ensure the continuity and smoothness of the nozzle feeding. Even further, such as... Figure 2 As shown, a limiting protrusion 217 is provided between the adjusting support plate 213 and the adjusting rotating shaft 212 to improve the stability of the assembly support; thereby improving the stability of the rotating feeding nozzle.

[0027] Specifically, in some implementations, such as Figure 1 and 3 As shown, the upper mold body 300 includes a first motion drive component 310 and a first heating template 320; the mounting end of the first motion drive component 310 is connected to the frame 1; the movable end of the first motion drive component 310 is connected to the top of the first heating template 320; the first heating groove 321 is disposed at the bottom of the first heating template 320. In some embodiments, such as... Figure 3 As shown, the first motion drive component 310 includes a first bracket 311, a first electric lead screw 312, a height adjustment cylinder 313, and a mounting base 314; the first bracket 311 is connected to the frame 1; the mounting end of the first electric lead screw 312 is connected to the first bracket 311; the movable end of the first electric lead screw 312 is connected to the mounting base 314; the mounting end of the height adjustment cylinder 313 is connected to the mounting base 314; and the movable end of the height adjustment cylinder 313 is connected to the first heating template 320. Further, as... Figure 3 As shown, the top of the first heating template 320 is provided with a guide rod 315; one end of the guide rod 315 is slidably connected to a limiting hole inside the mounting base 314. This structure, driven by the first electric lead screw 312, causes the first heating template 320 to reciprocate along the X-axis; combined with the driving action of the height adjustment cylinder 313, it causes the first heating template 320 to reciprocate along the Z-axis. This is to avoid collisions and ensure the smoothness and stability of the hot melt assembly.

[0028] Specifically, in some implementations, such as Figure 1 and 3As shown, the first heating template 320 includes a first heat insulation plate 322, a first heat conducting plate 323, a first electric heating tube 324, and a first abutment plate 325. The first heat insulation plate 322, the first heat conducting plate 323, and the first abutment plate 325 are sequentially stacked and connected as a whole. The top of the first heat insulation plate 322 is connected to the first motion drive component 310 (medium height adjustment cylinder 313). The first electric heating tube 324 is connected to the interior of the first heat conducting plate 323. The first heating groove 321 is disposed on the bottom surface of the first abutment plate 325 away from the first heat conducting plate 323. This structure achieves rapid heating of the first abutment plate 325 through the heat generation of the first electric heating tube 324 and the heat conduction of the first heat conducting plate 323, thereby promoting the speed and stability of hot melt assembly. Furthermore, the heat insulation effect of the first heat insulation plate 322 enhances the protection of the first motion drive component 310 (medium height adjustment cylinder 313), thereby improving the stability and safety of use.

[0029] Specifically, in some implementations, such as Figure 1 and 3 As shown, the lower mold body 400 includes a second motion drive component 410 and a second heating template 420; the second motion drive component 410 is connected to the frame 1 and is drivenly connected to the second heating template 420; the second heating template 420 is disposed below the upper mold body 300 (the first abutment plate 325 of the first heating template 320). This structure, through the motion drive of the second motion drive component 410, achieves the synchronization of movement between the second heating template 420 and the first heating template 320, thereby ensuring the smoothness of hot melt assembly.

[0030] In some implementation methods, such as Figure 3 As shown, the second motion drive component 410 includes a second electric lead screw 411 and a second bracket 412; the second bracket 412 is connected to the frame 1; the mounting end of the second electric lead screw 411 is connected to the second bracket 412; and the movable end of the second electric lead screw 411 is connected to the second heating template 420. This structure, through the synchronized conveying action of the second electric lead screw 411 and the first electric lead screw 312, achieves motion synchronization between the second heating template 420 and the first heating template 320, thereby ensuring smooth hot-melt assembly.

[0031] In some implementation methods, such as Figure 3As shown, the second heating template 420 includes a second heat insulation plate 422, a second heat conducting plate 423, a second electric heating tube 424, and a second abutment plate 425. The second heat insulation plate 422, the second heat conducting plate 423, and the second abutment plate 425 are sequentially stacked and connected as a whole. The bottom of the second heat insulation plate 422 is connected to the second motion drive component 410 (the second electric lead screw 411). The second electric heating tube 424 is connected to the interior of the second heat conducting plate 423. The second heating groove 421 is disposed on the side surface of the second abutment plate 425 away from the second heat conducting plate 423. This structure achieves rapid heating of the second abutment plate 425 through the heat generation of the second electric heating tube 424 and the heat conduction of the second heat conducting plate 423, thereby promoting the speed and stability of hot melt assembly. Furthermore, the heat insulation effect of the second heat insulation plate 422 enhances the protection of the second motion drive component 410 (the second electric lead screw 411), thereby improving the stability and safety of use.

[0032] The electric lead screw can be selected from models such as EPB-V, EBB-V, SBN-V / SBN, SBK, HBN, SDA-V, SBKH, SDAN-V, BIF, MDK, MBF, BNF, BNK, BIF-V / BIF, DIK, DIR, BNFN-V / BNFN, etc. The insulation board material can be glass wool, polystyrene foam (EPS / XPS), or polyurethane foam (PU), etc.
