DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Embodiment 1:

[0029] Reference Figure 1 , Attachment Figure 2 And attached Figure 3 An automatic carton packaging machine for carton processing includes a conveyor frame 10, two pulleys 12 are rotatably arranged inside the conveyor frame 10, a conveyor belt 11 is driven outside the two pulleys 12, and a support plate 13 is fixedly arranged between the two pulleys 12 and below the lower end surface of the upper conveyor belt 11. The above parts constitute a belt conveyor as a whole. During production and processing, the conveyor belt 11 will transport the cartons to be packaged and realize the effect of automatic loading and unloading.

[0030] For further information, see Attachment Figure 1 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 A first support frame 14 is fixedly arranged above the conveyor belt 11 on one side of the conveying frame 10, an air source 16 is fixedly arranged on the upper end surface of the first support frame 14, a heating box 17 is also fixedly arranged below the air source 16 and on the lower end surface of the first support frame 14, a plurality of metal heating meshes 18 are arranged in the heating box 17, a plurality of second jet holes 25 are arranged on the lower end surface of the heating box 17, a plurality of air supply pipes 19 are fixedly arranged on both sides of the heating box 17, and a plurality of first jet holes 20 are fixedly arranged on each air supply pipe 19.

[0031] The air source 16 plays the role of suction, and can continuously send the airflow to the heating box 17. A plurality of metal heating nets 18 are arranged in the heating box 17. After connecting to the power supply, the metal heating nets 18 can heat the airflow in the heating box 17, and heat the gas therein into dry and high-temperature gas. After the gas is heated, it can be ejected from the first jet hole 20 along the air delivery pipe 19, or directly ejected from the second jet hole 25. When the carton to be packaged is transported to the bottom of the first support frame 14, the high-temperature dry airflow can dry it from the top and the side.

[0032] For further information, see Attachment Figure 4 , Attachment Figure 6 And attached Fig. 9 A plurality of first electric push rods 21 are fixedly arranged on the upper side of the first support frame 14, and a partition assembly is slidably arranged between the first support frame 14 and the conveyor belt 11. The partition assembly includes a limit frame 22 connected to the output ends of the plurality of first electric push rods 21, and a gear 23 is rotatably arranged on the upper end surface of the limit frame 22. A drive motor 24 is also fixedly arranged on the limit frame 22, and the output end of the drive motor 24 is connected to the gear 23. Two racks 26 are meshed on both sides of the gear 23 on the upper end surface of the limit frame 22, and an isolation plate 27 is connected to one side of each rack 26. A plurality of triangular protrusions 28 are fixedly arranged on the end surface of the isolation plate 27 close to the limit frame 22.

[0033] Considering that cartons are stacked together before packaging, in order to preheat and dry the cartons more thoroughly, when the conveyor belt 11 transports the cartons to the bottom of the limit frame 22, the conveyor belt 11 will stop, so that the machine can dry them more thoroughly through the partition assembly. The production staff can control the output ends of the multiple first electric push rods 21 to move downward to lower the limit frame 22 as a whole to fix the cartons to be packaged to prevent the cartons from shifting, so as to facilitate subsequent packaging; after the limit frame 22 frames the carton, the drive motor 24 on the limit frame 22 can drive the gear 23 to rotate, and the two racks 26 on the outside of the gear 23 will move synchronously in opposite directions with the cooperation of the gear rack pair, so that the two isolation plates 27 on both sides of the rack 26 can approach the carton synchronously; each isolation plate 27 is provided with a plurality of triangular protrusions 28, and as the two isolation plates 27 approach the carton, the inclined surfaces on the triangular protrusions 28 will be inserted between the cartons, so that multiple cartons can be suspended by the triangular protrusions 28, so that the high-temperature dry airflow can pass through the gaps between the cartons to thoroughly dry each carton.

[0034] After drying is completed, the drive motor 24 can drive the gear 23 to reverse, and with the cooperation of the gear rack pair, the isolation plates 27 on both sides will synchronously withdraw from the carton and move away from the carton, and the carton will return to the stacked state after leaving the overhead support of multiple triangular protrusions 28; during the whole process, the stacked cartons are framed by the limit frame 22 so that they will not be displaced; then, the production personnel can control the output ends of the multiple first electric push rods 21 to move upward to move the limit frame 22 upward. At this time, the carton is not fixed, and the conveyor belt 11 can continue to drive the carton to move forward and enter the next process. Embodiment 2:

[0035] For further information, see Attachment Figure 1 With attached Figure 4A squeezing assembly is fixedly provided above the conveyor belt 11 on one side of the first support frame 14. As a further embodiment, when the dried cartons move to the bottom of the second support frame 29, the next group of cartons to be dried have been transported to the bottom of the first support frame 14 for drying. At this time, the conveyor belt 11 must stop and leave a period of time for the cartons under the first support frame 14 to dry. The stop time of the conveyor belt 11 is just enough to allow the squeezing assembly to perform a squeezing operation on the cartons below it; the squeezing operation can not only squeeze out excess air in the carton, but also play a role in leveling the carton.

[0036] For further information, see Attachment Figure 7 With attached Figure 8 The extrusion assembly includes a second support frame 29 fixedly arranged on 10, a second electric push rod 30 is fixedly arranged on the second support frame 29, an output end of the second electric push rod 30 extends to the bottom of the second support frame 29 and is connected to a connecting block 31, a sleeve 32 is fixedly arranged below the connecting block 31, a sliding seat 34 is slidably arranged below the sleeve 32, a spring 33 is connected between the connecting block 31 and the sliding seat 34, and an airbag 35 is also fixedly arranged on the lower end surface of the sliding seat 34.

[0037] The production staff can control the output end of the second electric push rod 30 to control the sliding seat 34 below it to move downward close to the carton and squeeze the carton through the airbag 35. The support plate 13 on the lower side of the conveyor belt 11 can play a supporting role; the setting of the spring 33 and the airbag 35 makes the machine's squeezing operation on the carton have a certain elasticity, and the airbag 35 can evenly distribute the squeezing pressure to the lower end surface of the entire airbag 35, protecting the carton from damaging the upper carton during the squeezing process.

[0038] After the extrusion is completed, the waiting conveyor belt 11 delivers the processed carton to the thermoforming machine 36 for thermoplastic packaging; finally, the conveyor belt 11 can transport the packaged carton out of the thermoforming machine 36. The thermoforming machine 36 is a prior art as a whole, and this solution will not be elaborated in detail.
