Background Art

[0002] At present, the core mold rotating tower and the automatic capping mechanism of the food roof bag filling equipment mostly adopt a multi-stage gear transmission structure to achieve step-by-step power transmission and ensure the synchronization of each process. However, the existing transmission mechanism has a complex structure and a large volume. It not only has low transmission accuracy and poor synchronization, but also requires the use of a large amount of lubricating oil and has a low hygiene level. In addition, in order to enrich the product line and expand sales channels, manufacturers usually need to fill beverages, milk, sugar and other materials with different viscosities and temperatures. However, due to the poor adaptability of the filling mechanism of the existing structure, different filling devices need to be configured, which increases the production cost and has poor practicality. In addition, the existing filling mechanism not only has poor filling volume accuracy, high failure rate, and difficult maintenance, but also has a slow filling operation speed and low production efficiency, which seriously affects the stability of the product filling quality.

[0003] At the same time, the guide box frame of the existing food filling equipment and the packaging carton mostly adopt a flat contact form. This traditional contact structure is easy to scratch the color printing and PE film on the outer surface of the packaging during the reciprocating lifting of the packaging carton, leaving irreparable friction marks, affecting the appearance quality of the product. Therefore, the lifting speed of the packaging carton during the filling process cannot be too fast, which limits the increase in the filling operation speed. In addition, the guide box frame of the existing structure has poor guiding smoothness, insufficient stability, loud noise, and poor practicality. Therefore, it is necessary to improve the roof bag filling equipment of the prior art. Summary of the invention

[0048] The injection piston assembly 65 has the same structure as the discharge piston assembly 69, and both include a hollow connection shell 81. The connection shell 81 is composed of a shell body 86. The upper end of the shell body 86 is provided with a shell feed end 87, and the lower end of the shell body 86 is provided with a shell discharge end 88. A circle of support pad limiting convex edges 89 are provided in the middle of the inner wall of the shell body 86, and a guide support pad 82 is fixedly provided on the support pad limiting convex edges 89. The guide support pad 82 is provided with a plurality of groups of support pad clamping protrusions 93, and a support pad material passing arc groove 94 is provided between two adjacent groups of support pad clamping protrusions 93; the guide support pad 82 is fixedly provided on the support pad limiting convex edges 89 inside the connection shell 81 by using the support pad clamping protrusions 93, and the material flows through the middle through cavity of the connection shell 81 through each support pad material passing arc groove 94 of the guide support pad 82.

[0049] A piston sealing groove 90 is arranged inside the shell body 86 and below the support pad limiting convex edge 89. A conical piston 83 is arranged in the piston sealing groove 90. The piston rod 84 on the upper part of the conical piston 83 is movably inserted into the middle through hole of the guide support pad 82, and the upper end of the piston rod 84 passes through the guide support pad 82 and extends upward. The upper end of the piston rod 84 is also sleeved with a spring limiting sleeve 91, and the spring limiting sleeve 91 is fixed on the piston rod 84 through a sleeve positioning pin 92. The return spring 85 sleeved on the outside of the piston rod 84 is arranged between the upper edge of the spring limiting sleeve 91 and the upper side of the guide support pad 82. Therefore, the piston rod 84 is lifted upward by the compression elastic force of the return spring 85 located between the guide support pad 82 and the spring limiting sleeve 91, so that the conical piston 83 closes the piston sealing groove 90 at the lower part of the shell body 86, that is, the injection piston assembly 65 or the discharge piston assembly 69 is blocked. In addition, during the filling process, the push piston 79 in the injection cylinder 62 is used to change the pressure inside the injection cylinder 62 along with the movement of the injection servo electric cylinder 63, and with the help of the pressure change, the conical piston 83 is driven to reciprocate along the piston rod 84, thereby opening or closing the injection piston assembly 65 or the discharge piston assembly 69.

[0050] The upper ends of the piston rods 84 of the conical pistons 83 of the injection piston assembly 65 and the discharging piston assembly 69 are also provided with opening cylinder driving ends 95 for facilitating the piston assembly to be in a normally open state. The opening cylinder driving end 95 of the piston rod 84 of the injection piston assembly 65 is connected to the telescopic end of the injection piston opening cylinder 72 arranged at the top of the filling barrel 58 through the piston pushing long rod 78 located inside the filling barrel 58; the opening cylinder driving end 95 of the piston rod 84 of the discharging piston assembly 69 is connected to the telescopic end of the discharging piston opening cylinder 73 arranged at the upper port of the discharging tee 67. In the process of cleaning the filling device, the injection piston opening cylinder 72 (including the piston pushing long rod 78) and the discharging piston opening cylinder 73 are used to press the corresponding conical pistons 83 respectively, so that the injection piston assembly 65 and the discharging piston assembly 69 are both in a normally open state, which is convenient for continuous cleaning of the servo filling device 14.

[0051] A servo filling lifting mechanism 15 is provided below the filling riser 68 at the discharge end of the servo filling device 14. The servo filling lifting mechanism 15 includes a lifting connection frame 96, on which a vertically arranged filling lifting rod 105 is provided, and the upper part of the filling lifting rod 105 is connected to the spacing horizontal plate 97 at the upper part of the lifting connection frame 96 through a lifting guide sleeve 107. The lower part of the filling lifting rod 105 is fixedly connected to the belt body of the annular lifting synchronous belt 103 arranged along the lifting direction of the lifting rod through a synchronous belt connecting seat 104. The rotating shaft of the lifting pulley 102 at one end of the annular lifting synchronous belt 103 is connected to the output end of the lifting servo motor 99 provided on the lifting motor fixing frame 98; the rotating shaft of the lifting pulley 102 at the other end of the annular lifting synchronous belt 103 is connected to the pulley tensioning frame 100 through a bearing, and the pulley tensioning frame 100 is also provided with a tensioning adjustment bolt 101.

[0052] A lifting sucker 106 is provided on the upper end of the filling lifting rod 105 of the servo filling lifting mechanism 15, which is located above the spacing horizontal plate 97; a lifting vacuum connection port is provided at the lower end of the filling lifting rod 105. In addition, an anti-torsion sway guide rod 109 arranged in a direction parallel to the lifting rod is also provided on the side of the filling lifting rod 105; the upper part of the anti-torsion sway guide rod 109 is fixedly connected to the fixed seat 108 and the spacing horizontal plate 97 through a guide rod, and the lower part of the anti-torsion sway guide rod 109 is slidably connected to the side of the synchronous belt connecting seat 104 through an anti-torsion sway guide sleeve 110. Thus, the lifting servo motor 99 is used to drive the annular lifting synchronous belt 103 to rotate, so as to drive the synchronous belt connection seat 104 fixedly connected on the belt surface and the lifting rod thereon to reciprocate up and down along the lifting guide sleeve 107, and then the lifting suction cup 106 at the upper end of the lifting rod is used to drive the packaging paper box 9 to move up and down in the paper box lifting space 113, so as to facilitate the high-speed filling of the material. At the same time, the anti-torsion guide sleeve 110 is reciprocated on the vertically arranged anti-torsion guide rod 109 to guide the synchronous belt connection seat 104 and the filling lifting rod 105 thereon to rotate and rise and fall with the annular lifting synchronous belt 103, and effectively prevent the filling lifting rod 105 from twisting and falling during high-speed lifting, so as to ensure the stability of the filling and lifting of the packaging paper box 9.

[0053] A box guide frame mechanism 16 is also provided between the upper end of the servo filling lifting mechanism 15 and the filling riser 68 of the servo filling device 14. A box top preheating and sealing mechanism 17 is provided in front of the filling riser 68 of the servo filling device 14 along the conveying direction of the packaging box 9, and a branding date printing mechanism 123 is provided in front of the box top preheating and sealing mechanism 17; a box out conveying mechanism 18 is provided at the box outlet at the other end of the box conveying mechanism 10. The box guide frame mechanism 16 includes a connecting base 111 connected to the filling machine body 1, and two groups of upper and lower L-shaped support frames 112 are provided on the connecting base 111; a vertically arranged box lifting space 113 is provided inside the L-shaped support frame 112. The cross section of the box lifting space 113 is rectangular, and two groups of roller box guide frames 114 arranged vertically are provided at the diagonal position of the rectangular cross section of the box lifting space 113. The roller guide box frame 114 is composed of a guide box connecting frame 115, and the guide box connecting frame 115 is respectively connected to the ends of the two extended ends of the L-shaped support frame 112. In addition, on the guide box connecting frame 115 of each roller guide box frame 114, on two adjacent vertical surfaces facing the paper box lifting space 113, a plurality of groups of longitudinal rollers 116 and transverse rollers 117 are respectively arranged, and the longitudinal rollers 116 and the transverse rollers 117 are respectively arranged in the vertical direction.

[0054] The guide box connecting frame 115 of the roller guide box frame 114 includes a connecting frame body 118, and roller mounting holes 119 arranged along the vertical direction are respectively provided on two adjacent vertical surfaces of the connecting frame body 118; and then the longitudinal rollers 116 and the transverse rollers 117 are respectively installed in the roller mounting holes 119 on the two adjacent vertical surfaces of the connecting frame body 118, so as to utilize a plurality of groups of longitudinal rollers 116 and transverse rollers 117 arranged at 90 degrees to each other to roll and guide the packaging paper box 9 in the paper box lifting space 113 that is reciprocatedly lifted and lowered by the servo filling lifting mechanism 15. At the same time, in order to improve the reliability of the device, the roller mounting holes 119 respectively arranged on the two adjacent vertical surfaces of the connecting frame body 118 adopt a structural form of vertically spaced and staggered arrangement, that is, the longitudinal rollers 116 and the transverse rollers 117 are not at the same horizontal height position; thereby, the guiding stability of the roller guide box frame 114 is increased by utilizing the longitudinal rollers 116 and the transverse rollers 117 that are vertically spaced and staggered arrangement on two adjacent vertical surfaces. The longitudinal roller 116 and the transverse roller 117 arranged on the guide box connecting frame 115 of the roller guide box frame 114 have the same structure, both of which include a roller wheel body 120, a roller shaft 121 is arranged in the middle of the roller wheel body 120, and a roller connecting part 122 is arranged at one end of the roller shaft 121; then, the roller wheel body 120 is respectively connected to the roller mounting holes 119 on the two adjacent vertical surfaces of the guide box connecting frame 115 through the roller connecting part 122, so that the roller wheel body 120 can form rolling contact with the packaging paper box 9.

[0055] When the high-speed fully automatic roof bag filling machine is used, first, the carton drawing and forming device 3 draws and forms the sheet carton at the bottom of the carton sheet library 2, and sets the drawn and formed packaging carton 9 one by one on the pressure-sealing core mold 22 of the core mold rotating tower 5. Then, the transmission servo motor 26 drives the indexing turntable 21 of the core mold rotating tower 5 to rotate indexingly, and the carton bottom heater 4, the carton bottom pre-folding mechanism 6 and the carton bottom pressure-sealing mechanism 7 above the core mold rotating tower 5 are used respectively, and the bottom of the packaging carton 9 on the pressure-sealing core mold 22 is gradually pressed and sealed with the indexing rotation of the indexing turntable 21. After that, the packaging carton 9 at the bottom of the core mold rotating tower 5 after the pressure-sealing is separated downward from the pressure-sealing core mold 22 by the demoulding suction cup on the demoulding mechanism 8 below the core mold rotating tower 5. The packaging paper box 9 separated from the core mold rotating tower 5 is transported to the capping station of the automatic capping mechanism 12 through the paper box conveying mechanism 10; at the same time, the capping synchronous pulley 33 connected to the rear end of the telescopic shaft 35 in the fixed sleeve 34 of the automatic capping mechanism 12 is connected to the turntable synchronous pulley 25 of the core mold rotating tower 5 through the double-sided toothed synchronous belt 27, and the rotation direction of the capping synchronous pulley 33 is changed by the cooperation of the reversing bending section 45 of the double-sided toothed synchronous belt 27 and the synchronous belt reversing wheel 32. Then, the capping synchronous pulley 33 and the turntable synchronous pulley 25 are rotated synchronously and in opposite directions, so that the capping pressing plate 36 at the front end of the telescopic shaft 35 rotates at intervals of 180 degrees, and the capping pressing plate 36 at the front end of the telescopic shaft 35 is driven by the capping telescopic cylinder 29 to cooperate with the ultrasonic cap welding device 11 to squeeze, so that the box cover conveyed by the continuous cap feeding device 13 is firmly welded on the packaging paper box 9.

[0056] The packaging carton 9 with the box cover welded is further conveyed forward by the carton conveying mechanism 10 to the bottom of the filling standpipe 68 at the lower end of the servo filling device 14; then, the servo filling lifting mechanism 15 drives the filling lifting rod 105 to rise, thereby quickly lifting the packaging carton 9 to the filling starting position. Subsequently, the injection servo electric cylinder 63 of the servo filling device 14 drives the push piston 79 in the injection cylinder 62 to move downward, and with the help of the change in the internal pressure of the injection cylinder 62, the conical piston 83 of the injection piston assembly 65 between the injection pipe 61 and the injection tee 64 is opened (at this time, the conical piston 83 of the discharge piston assembly 69 at the upper end of the filling standpipe 68 is in a closed state), so that the material in the filling barrel 58 flows quantitatively into the injection cylinder 62 through the injection pipe 61. Then, the injection servo electric cylinder 63 pushes the push piston 79 in the injection cylinder 62 to move upward, and by virtue of the change in the internal pressure of the injection cylinder 62, the conical piston 83 of the discharge piston assembly 69 between the discharge tee 67 and the filling standpipe 68 is opened (at this time, the conical piston 83 of the injection piston assembly 65 at the lower end of the injection tube 61 is in a closed state by virtue of the return spring 85), and then the material in the injection cylinder 62 is discharged to the filling standpipe 68 through the injection elbow 66 and the discharge tee 67, and the material is quickly filled with high-precision quantitative quantity. In the process of filling the material into the packaging carton 9 through the filling standpipe 68, as the liquid level in the packaging carton 9 rises, the lifting suction cup 106 at the upper end of the filling lifting rod 105 of the servo filling lifting mechanism 15 gradually pulls the packaging carton 9 downward (the position of the filling standpipe 68 is fixed), and the filling operation is completed quickly and smoothly.

[0057] At the same time, in the process of the packaging carton 9 being lifted and lowered back and forth with the servo filling lifting mechanism 15, the two roller guide box frames 114 arranged diagonally on the L-shaped support frame 112 of the guide box frame mechanism 16, and the plurality of groups of longitudinal rollers 116 and transverse rollers 117 arranged at 90 degrees to each other on each roller guide box frame 114, are used to guide the movement of the packaging carton 9 in the carton lifting space 113 by rolling; thereby effectively preventing the color printing and PE film on the outer surface of the packaging carton 9 from being scratched, avoiding irreparable friction marks, ensuring the appearance quality of the product, and facilitating the improvement of the filling operation speed. Afterwards, the carton conveying mechanism 10 conveys the filled packaging carton 9 one by one to the bottom of the carton top preheating and sealing mechanism 17, so as to seal the top of the upper opening of the packaging carton 9. The packaging carton 9 with the top sealed (sealed) is transported to the subsequent conveying line via the box delivery mechanism 18 at the end of the carton conveying mechanism 10.
