An aseptic packaging machine for instant tea

Abstract

This invention relates to the field of food packaging technology and discloses an aseptic packaging machine for instant tea, including a packaging table, a discharging component, a folding component, a first heat-sealing component, a flaring component, a feeding component, a grooving component, and a second heat-sealing component. This invention first uses the discharging component, folding component, and first heat-sealing component to vertically heat-seal the packaging film. Then, the flaring component and feeding component complete the bagging of tea powder. Next, the grooving component and second heat-sealing component simultaneously expel air from the packaging bag, grooving the bag and heat-sealing the top. The entire process requires no manual operation, thus avoiding contamination from manual bagging. Furthermore, by squeezing out as much gas as possible from the packaging bag before sealing, fungal growth is prevented. This reduces the difficulty of sterilization in the production workshop while achieving fully automated production.

DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. The present invention will be described in detail with reference to the drawings and in combination with the embodiments.

[0053] In one embodiment of the present invention, see Figures 1 to 19 , an instant tea aseptic packaging machine, comprising a packaging table 1, a discharging assembly 69, a folding assembly 70, a first heat sealing assembly 71, a flaring assembly 72, a blanking assembly 73, a grooving assembly 74, and a second heat sealing assembly 75;

[0054] The discharging assembly 69 is mounted on one end of the packaging table 1; the folding assembly 70 is mounted on the packaging table 1 and is arranged on the discharging end side of the discharging assembly 69; the first heat sealing assembly 71 is mounted on the packaging table 1 and is arranged on the discharging end side of the folding assembly 70; the flaring assembly 72 is mounted on the packaging table 1 and is arranged on the discharging end side of the first heat sealing assembly 71; the blanking assembly 73 is mounted on the packaging table 1 and is arranged directly below the flaring assembly 72; the grooving assembly 74 is mounted on the packaging table 1 and is arranged on the discharging end side of the flaring assembly 72; the second heat sealing assembly 75 is mounted on the packaging table 1 and is arranged on the discharging end side of the grooving assembly 74;

[0055] The present invention first installs the material roll with the packaging film rolled up by the discharging component 69, and pulls the packaging film by the setting of the cutting component 74, and tensions the packaging film and releases it by the damping force generated by the discharging component 69. In this process, the packaging film first passes through the folding component 70, so that the packaging film is centrally symmetrically folded and folded under the action of the folding component 70, and the folded packaging film enters the first heat sealing component 71, so that the packaging film is heat-sealed in the vertical direction by the first heat sealing component 71, and a margin is left at the top opening of the packaging film. At this time, the packaging film is heat-sealed and sealed on both sides, and an opening is left at the top, and in the process of releasing the packaging film, the expanding component 72 rotates synchronously with the release of the packaging film, so that the driving end of the expanding component 72 is cyclically inserted into the opening at the top of the packaging bag, and when the expanding component 72 and the packaging bag move synchronously to the bottom of the blanking component 73, the expanding component 72 opens, so that the opening at the top of the packaging bag is pulled to both sides to open, thereby expanding the opening at the top of the packaging bag, and the expanding component and the first heat sealing component rotate synchronously. The remaining unheat-sealed residue on the top of the packaging bag between the components is synchronously expanded under the drive of the expanding component, so as to facilitate the subsequent insertion of the expanding component 72 into the packaging bag, thereby avoiding the generation of an empty bag due to the failure of the expanding component 72 to be inserted. At this time, the same weight of tea powder can be injected into the opened packaging bag through the blanking component 73, and then the packaging bag containing tea powder enters the grooving component 74, so that the heat-sealed parts between the packaging bags after the feeding are grooved by the grooving component 74, but not completely cut off, so as to facilitate the tearing of adjacent packaging bags. At the same time, the air in the packaging bag is squeezed out by the setting of the grooving component 74, and the grooving component 74 is completed for each rotation of the grooving component 74. Then, the packaging bag after the air is exhausted enters the second heat-sealing component 75 under the rolling pressure of the grooving component 74, so that the opening at the top of the packaging bag is heat-sealed and sealed. The entire processing process does not require manual operation, thereby avoiding the contamination of miscellaneous bacteria caused by manual bagging, and the gas in the packaging bag is squeezed out as much as possible before the sealed packaging, thereby avoiding the growth of fungi.

[0056] In one case of this embodiment, see Figure 2 and Figure 10 to Figure 14The flaring assembly 72 includes a pulley 25, a belt 26, a fixed plate 28, and a flaring rod 32; a support frame 23 is fixedly connected to the packaging table 1, and a mounting shaft 24 is rotatably connected in the support frame 23, the pulley 25 is fixedly connected to the mounting shaft 24, the belt 26 is installed between the pulleys 25, a first motor 27 is fixedly connected to the support frame 23, and the output shaft of the first motor 27 is fixedly connected to the mounting shaft 24, and the first motor 27 is a servo motor; the fixed plate 28 is fixedly connected between the belts 26, and the spacing between the fixed plates 28 is the same as the length of the packaging bag, and a material injection port 29 is provided in the fixed plate 28, and the material injection port 29 is provided between the belts 26, and the fixed plate 28 is fixedly connected at both ends. There is a second fixed rod 30, on which a second sliding block 31 is slidably connected, one end of the flaring rod 32 is rotatably connected to the second sliding block 31, and the other end of the flaring rod 32 is rotatably connected to each other; a telescopic rod 33 is slidably connected in the fixed plate 28, one end of the telescopic rod 33 is fixedly connected to the second sliding block 31, and the other end of the telescopic rod 33 is fixedly connected to a driving slider 35, and a third spring 34 sleeved on the telescopic rod 33 is provided on the side of the second sliding block 31 away from the flaring rod 32, a third fixed frame 36 is fixedly connected to the packaging table 1, and a driving slide 37 is fixedly connected to the third fixed frame 36, and a notch 38 is provided in the driving slide 37, and the notch 38 cooperates with the driving slider 35 and the telescopic rod 33;

[0057] The flaring assembly 72 drives the mounting shaft 24 to rotate through the first motor 27, and the mounting shaft 24 drives the pulley 25 to rotate, and then drives the belt 26 to rotate and move through the pulley 25, and the belt 26 drives the fixed plate 28 to move. When the fixed plate 28 does not contact the driving slide groove 37, the driving slider 35 has no contact with the notch 38. At this time, the second sliding block 31 moves to the middle of the fixed plate 28 under the elastic push of the third spring 34, and the second sliding block 31 drives the flaring rods 32 to contract and fold each other, so that the angle between the flaring rods 32 is reduced, and then when the belt 26 drives the fixed plate 28 to rotate and descend between the packaging films, the rotating connection of the flaring rod 32 is inserted into the top loading port of the packaging film;

[0058] Then, as the belt 26 rotates, the fixed plate 28 drives the driving slider 35 to move into the driving slot 37. At this time, the driving slider 35 and the telescopic rod 33 slide and insert into the notch 38. At this time, the driving slider 35 moves along the shape of the driving slot 37. When the driving slider 35 moves toward the protruding section of the driving slot 37, the driving slider 35 moves in the direction away from the belt 26 under the action of the driving slot 37. The driving slider 35 drives the second sliding block 31 to move through the telescopic rod 33. The second sliding block 31 compresses the third spring 34, and the distance between the second sliding blocks 31 gradually increases. In this process, the flaring rods 32 expand each other, thereby increasing the angle between the flaring rods 32. At this time, the flaring rods 32 drive the top feeding port of the packaging bag to open, thereby realizing the expansion of the loading port of the packaging bag.

[0059] Then, when the driving slider 35 slides out of the driving slot 37, the driving slider 35 is no longer pushed by the driving slot 37. At this time, the third spring 34 is no longer compressed and releases its elastic potential energy, thereby pushing the second sliding block 31 to reset. At this time, the flaring rod 32 shrinks and folds again, and then moves with the rotation of the belt 26, and is rotated and lifted from the packaging bag, thereby rotating and pulling the flaring rod 32 out of the packaging bag.

[0060] In one case of this embodiment, see Figure 4 The discharging assembly 69 includes a first fixed frame 2 and a discharge roller 3; the first fixed frame 2 is fixedly connected to the packaging table 1, the discharge roller 3 is rotatably installed in the first fixed frame 2, the discharge roller 3 is rolled up with a packaging film, and the mounting shaft 24 of the discharge roller 3 is provided with a damper 4 fixedly connected to the first fixed frame 2;

[0061] The discharging component 69 reels the packaging film through the discharging roller 3, and applies traction force to the packaging film when pulling the packaging film through the cutting groove component 74. The packaging film drives the discharging roller 3 to be pulled and discharged. At the same time, a reverse damping force is applied to the discharging roller 3 through the damper 4, and then the packaging film is elastically tensioned through the mutual cooperation of the damping force and the traction force.

[0062] In one case of this embodiment, see Figures 5 to 8The folding assembly 70 includes a feed table 5, a folding roller 9, and a clamping roller 10; the feed table 5 is fixedly connected to the packaging table 1, and a folding guide plate 6 is fixedly connected to the side of the packaging table 1 away from the discharging assembly 69, and a guide roller 7 is rotatably installed on the feed table 5, and hangers 8 fixedly connected to the packaging table 1 are arranged on both sides of the folding guide plate 6, and folding rollers 9 are rotatably connected to the bottom of the hanger 8, and the folding rollers 9 are arranged between the folding guide plates 6, and the clamping rollers 10 are arranged on the side of the folding guide plate 6 away from the feed table 5, and the clamping rollers 10 are symmetrically arranged with the folding rollers 9 as the center, and the clamping rollers 10 are rotatably connected to the hangers 8;

[0063] The folding component 70 first guides the feeding direction of the packaging film released by the discharging component 69 through the guide roller 7, and then folds and gathers the two sides of the packaging film through the folding guide plate 6. In the folding process, the bottom of the packaging film is pressed down by the folding roller 9, and at the same time, the packaging film is roll-folded by the mutual cooperation of the clamping roller 10, so as to produce a crease in the middle of the packaging film.

[0064] In one case of this embodiment, see Fig. 9 The first heat sealing assembly 71 includes a first heat sealing block 11, a first clamping heat insulating block 16, and a first telescopic pump 21; the first heat sealing block 11 is fixedly connected to the packaging table 1, the first heat sealing block 11 is fixedly connected to a first fixed clamping cylinder 15, the packaging table 1 is fixedly connected to a second fixed frame 12, the second fixed frame 12 is fixedly connected to a first fixed rod 13, the first fixed rod 13 is slidably connected to a first sliding block 18, the first sliding block 18 is fixedly connected to a first telescopic clamping cylinder 14, the first clamping heat insulating block 16 is slidably mounted on the first telescopic clamping cylinder In the cylinder 14, a first sliding plate 17 is fixedly connected to the side of the first clamping heat-insulating block 16 away from the first heat-sealing block 11, and the first sliding plate 17 is slidably connected to the first fixed rod 13.

[0065] The first heat sealing component 71 heats the first heat sealing block 11 by electric heating. When the first heat sealing component 71 is processed, the first sliding plate 17 can be driven by the first telescopic pump 21 to move along the direction of the first fixed rod 13. The first sliding plate 17 elastically pushes the first sliding block 18 through the second spring 20. The first sliding block 18 drives the first telescopic clamping cylinder 14 to move toward the first fixed clamping cylinder 15, so that the packaging bag is clamped and fixed by the arrangement of the first fixed clamping cylinder 15 and the first telescopic clamping cylinder 14. Then, the first sliding plate 17 drives The first clamping insulation block 16 continues to move, thereby compressing the second spring 20. When the first clamping insulation block 16 is close to the first heat sealing block 11, the first clamping insulation block 16 and the first heat sealing block 11 cooperate with each other to elastically clamp the packaging bag, and heat-seal the packaging bag through the first heat sealing block 11. After the heat sealing is completed, the first telescopic pump 21 is reset, and the first clamping insulation block 16 and the first telescopic clamping tube 14 are reset synchronously, thereby releasing the clamping of the packaging bag. At this time, the packaging bag between the first clamping insulation block 16 and the first heat sealing block 11 can be transferred again.

[0067] The blanking assembly 73 is first connected to the vacuum pump device through the connection port 43, and the tea powder is transported through the setting of the feeding pipe 40, so that the tea powder is gradually injected into the storage barrel 41, so that the tea powder in the storage barrel 41 is lifted by the support block 48, and the weight of the tea powder is transmitted to the weight sensing telescopic motor 45 through the support block 48 and the connecting rod 46, so that the weight of the tea powder on the support block 48 is sensed by the weight sensing telescopic motor 45. When the weight sensing telescopic motor 45 detects the weight of the tea powder on the support block 48, the weight of the tea powder on the support block 48 is sensed. After the amount reaches a certain amount, the weight-sensing telescopic motor 45 drives the supporting block 48 to move into the discharge barrel 42 through the connecting rod 46. When the supporting block 48 moves into the discharge barrel 42, the storage barrel 41 opens, and the tea powder falls into the discharge barrel 42 under the action of gravity, and then falls along the drop port 44, and finally falls into the packaging bag along the injection port 29. When the connecting rod 46 falls, the connecting rod 46 drives the valve block 47 to move synchronously, thereby closing the connection between the feed pipe 40 and the storage barrel 41, thereby preventing excessive injection of tea powder.

[0068] In one case of this embodiment, see Figure 16 to Figure 18 The grooving assembly 74 includes a rotating shaft 50, a prism 51, a transmission roller 52, and a fourth spring 53; a fifth fixed frame 49 is fixedly connected to the packaging table 1, the rotating shaft 50 is rotatably connected in the fifth fixed frame 49, the prism 51 is arranged in the transmission roller 52, and a rib groove is arranged in the transmission roller 52, the circumference of the transmission roller 52 is the same as the length of the packaging bag, the fourth spring 53 is installed between the rib groove and the prism 51, and the fourth spring 53 is distributed in a circle with the prism 51 as the center, a cutting knife 55 is installed on the outer wall of the transmission roller 52, and a support plate 54 is fixedly connected to the bottom of the transmission roller 52, a gear 56 is fixedly connected to the rotating shaft 50, and the gears 56 are meshed with each other, and a second motor 57 is fixedly connected to the fifth fixed frame 49, and the output shaft of the second motor 57 is fixedly connected to the rotating shaft 50, and the second motor 57 is a servo motor;

[0069] The grooving assembly 74 drives the rotating shaft 50 to rotate through the second motor 57, and drives the rotating shaft 50 to rotate synchronously in the opposite direction through the mutual engagement of the gears 56. The rotating shaft 50 drives the driving roller 52 to rotate through the prism 51 and the fourth spring 53. The driving roller 52 rotates synchronously in the opposite direction, and the driving roller 52 elastically clamps and fixes the packaging bag between the driving rollers 52 under the action of the fourth spring 53. At the same time, the packaging bag is rolled and conveyed through the synchronous reverse rotation of the driving roller 52, and the air in the packaging bag is squeezed out. When the driving roller 52 drives the cutting knife 55 to the heat-sealed part of the packaging bag, the cutting knife 55 can be used to cut a groove. By setting the circumference of the driving roller 52 to be the same as the length of the packaging bag, the driving roller 52 rotates one circle to complete a groove, and then the packaging bag and the cutting knife 55 are rotated and positioned.

[0070] In one case of this embodiment, see Fig.19 The second heat sealing assembly 75 includes a second heat sealing block 58, a second clamping heat insulating block 64, and a second telescopic pump 66; the second heat sealing block 58 is fixedly connected to the packaging table 1, and the second heat sealing block 58 is fixedly connected to the second fixed clamping cylinder 59, the packaging table 1 is fixedly connected to a sixth fixed frame 60, the sixth fixed frame 60 is fixedly connected to a third fixed rod 61, the third fixed rod 61 is slidably connected to a third sliding block 62, the third sliding block 62 is fixedly connected to a second telescopic clamping cylinder 63, the second clamping heat insulating block 64 is slidably mounted on the second telescopic clamping cylinder In the cylinder 63, a second sliding plate 65 is fixedly connected to the side of the second clamping heat-insulating block 64 away from the second heat-sealing block 58, and the second sliding plate 65 is slidably connected to the second fixed rod 30. The second telescopic pump 66 is installed on the sixth fixed frame 60, and the output shaft of the second telescopic pump 66 is fixedly connected to the second sliding plate 65. A fifth spring 67 sleeved on the third fixed rod 61 is provided on the side of the second sliding block 31 away from the second sliding plate 65, and a sixth spring 68 sleeved on the first fixed rod 13 is provided between the second sliding plate 65 and the third sliding block 62;

[0071] The second heat sealing assembly 75 heats the second heat sealing block 58 by electric heating. When the second heat sealing assembly 75 is processed, the second sliding plate 65 can be driven by the second telescopic pump 66 to move along the direction of the third fixed rod 61. The second sliding plate 65 elastically pushes the third sliding block 62 through the sixth spring 68, and the third sliding block 62 drives the second telescopic clamping cylinder 63 to move toward the second fixed clamping cylinder 59, so that the packaging bag is clamped and fixed by the second fixed clamping cylinder 59 and the second telescopic clamping cylinder 63. Then, the second sliding plate 65 drives the third sliding block 62 to move toward the second fixed clamping cylinder 59. The second clamping insulation block 64 continues to move, thereby compressing the sixth spring 68. When the second clamping insulation block 64 is close to the second heat sealing block 58, the second clamping insulation block 64 and the second heat sealing block 58 cooperate with each other to elastically clamp the packaging bag, and heat-seal the packaging bag through the second heat sealing block 58. After the heat sealing is completed, the second telescopic pump 66 is reset, and the second clamping insulation block 64 and the second telescopic clamping tube 63 are reset synchronously, thereby releasing the clamping of the packaging bag. At this time, the packaging bag between the second clamping insulation block 64 and the second heat sealing block 58 can be transferred again.

[0072] In one case of this embodiment, see Figure 3 The packaging table 1 is provided with bottom rollers 22 which are evenly distributed. The bottom rollers 22 cooperate with the packaging bag. The present invention lifts and fixes the bottom of the packaging bag by setting the bottom rollers 22, thereby preventing the packaging bag from falling and deforming due to the influence of gravity.

[0073] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
