Detailed Implementation

[0048] To make the objectives, advantages and features of this utility model clearer, the following describes in further detail an automatic liquid bag packing device proposed by this utility model in conjunction with the accompanying drawings and specific embodiments.

[0049] Reference Figure 1 , Figure 2 and Figure 3 The present invention relates to an automatic liquid bag packing device, comprising a main support 1, an inner support 2, a bag conveying mechanism 4, a feeding drive mechanism 5, a lifting mechanism 6, a box conveying mechanism 7, a limit baffle 9, a box positioning baffle 8, a box baffle support 81, a lifting guide column 82, a box baffle lifting cylinder 83, a pre-stored box top mechanism 74, and a pair of feeding platforms 3.

[0050] like Figure 1 As shown, the bag conveying mechanism 4 is a stainless steel roller conveyor belt. The bag conveying mechanism 4 is electrically connected to an external control device. The outlet direction of the liquid bag on the bag conveying mechanism 4 is defined as rear, and the inlet direction as front. Therefore, the bag conveying mechanism 4 is located on the front side of the main support 1. For example... Figure 4 As shown, a bag conveying detection sensor 41 is installed at the outlet position of the bag conveying mechanism 4. The bag conveying detection sensor 41 is a photoelectric sensor. The bag conveying detection sensor 41 is used to detect whether a liquid bag is conveyed by the bag conveying mechanism 4 to a pair of unloading platforms 3. The bag conveying detection sensor 41 is electrically connected to an external control device.

[0051] like Figure 1 , Figure 3 and Figure 4As shown, the inner support 2 is installed inside the main support 1. The rear side of the inner support 2 is hinged to the main support 1, and the front side of the inner support 2 is connected to the main support 1 through the lifting mechanism 6. Preferably, both the main support 1 and the inner support 2 are frame structures. The bottom of the rear side of the inner support 2 is hinged to the main support 1. The lifting mechanism 6 includes an adjusting bracket 62 and a pair of lifting cylinders 61. The adjusting bracket 62 is located below the front side of the inner support 2. Each end of the adjusting bracket 62 is provided with two elongated holes extending vertically. Four bolts pass through the corresponding elongated holes and are connected to the main support 1. The elongated holes allow the position of the adjusting bracket 62 to be adjusted vertically, thereby allowing the tilt angle of the inner support 2 to be adjusted, which can meet the packing requirements of different packaging specifications. The bottom of the cylinder body of the pair of lifting cylinders 61 is hinged to the adjusting bracket 62, and the output end of the pair of lifting cylinders 61 is hinged to the bottom of the front side of the inner support 2. The solenoid valves of the pair of lifting cylinders 61 are electrically connected to an external control device. Before the pair of feeding platforms 3 are opened to allow the liquid bag to fall into the bag-dropping auxiliary funnel 54, the output ends of the pair of lifting cylinders 61 are retracted, so that the pair of feeding platforms 3 are switched from the inclined position to the horizontal position. This can improve the bag-dropping stability, thus making the bag-dropping stability of this automatic liquid bag packing device strong.

[0052] A pair of feeding platforms 3 are symmetrically hinged to the inner support 2. The inlets of the feeding platforms 3 correspond to the outlets of the bag conveying mechanism 4. Each feeding platform 3 is equipped with multiple non-powered rollers. A bag positioning detection sensor 31 is installed on the inner support 2. The bag positioning detection sensor 31 is a photoelectric sensor used to detect whether there is a liquid bag at a predetermined position on the pair of feeding platforms 3. The bag positioning detection sensor 31 is electrically connected to an external control device.

[0053] like Figure 3 As shown, the feeding drive mechanism 5 includes a feeding cylinder 51, a connecting rod 52, and a pair of connecting rods 53. The cylinder body of the feeding cylinder 51 is fixedly mounted on the upper part of the inner support 2. The output end of the feeding cylinder 51 faces downward and is fixedly connected to the middle of the connecting rod 52. The solenoid valve of the feeding cylinder 51 is electrically connected to an external control device. One end of the pair of connecting rods 53 is hinged to both ends of the connecting rod 52, and the other end of the pair of connecting rods 53 is hinged to the side of the pair of feeding platforms 3 that is away from each other. When the output end of the feeding cylinder 51 retracts, the output end of the feeding cylinder 51 drives the connecting rod 52 to move upward. The connecting rod 52 drives the pair of feeding platforms 3 to rotate through the pair of connecting rods 53, thereby opening the pair of feeding platforms 3. When the output end of the feeding cylinder 51 extends, the output end of the feeding cylinder 51 drives the connecting rod 52 to move downward. The connecting rod 52 drives the pair of feeding platforms 3 to rotate in the opposite direction through the pair of connecting rods 53, thereby closing the pair of feeding platforms 3.

[0054] like Figure 1As shown, the limiting baffle 9 is set on the inner support 2 and located at the rear end of the pair of unloading platforms 3. After the liquid bag is conveyed to the pair of unloading platforms 3 in an inclined position, the liquid bag can move downward on the pair of unloading platforms 3 under the action of gravity and with the help of the unpowered roller until the liquid bag is restricted by the limiting baffle 9 and can no longer move.

[0055] This utility model discloses an automatic liquid bag packing device, which further includes a limiting baffle adjustment frame 91 and two baffle adjustment handles 92. Each end of the limiting baffle adjustment frame 91 has a connecting plate, and each connecting plate has two elongated holes extending vertically. Four bolts pass through the corresponding elongated holes and are connected to the inner support 2, allowing the height of the limiting baffle 9 to be adjustable. Two adjusting rods connected to the limiting baffle 9 pass through through holes in the limiting baffle adjustment frame 91. The two baffle adjustment handles 92 are threaded onto the limiting baffle adjustment frame 91, and their inner ends extend into the through holes in the limiting baffle adjustment frame 91 and press against the two adjusting rods. Thus, the adjustment position of the two adjusting rods can be limited by the two baffle adjustment handles 92, allowing the position of the limiting baffle 9 to be adjusted in the front-back direction. Using this structure, the position of the limiting baffle 9 can be precisely adjusted, meeting the packing requirements of different packaging specifications.

[0056] like Figure 4 As shown, the bottom of the inner support 2 is connected to a bag dropping auxiliary funnel 54. The bag dropping auxiliary funnel 54 is set at the outlet of a pair of feeding platforms 3 to guide the liquid bag to fall accurately into the box 10 located at the packing position. This setting can improve the packing reliability.

[0057] like Figure 1 and Figure 4 As shown, the box conveyor 7 is a stainless steel roller conveyor belt. The box conveyor 7 is located below a pair of unloading platforms 3. The conveying direction of the box conveyor 7 is perpendicular to the conveying direction of the bag conveyor 4. The middle of the box conveyor 7 corresponds to the outlet of the bag dropping auxiliary funnel 54. The box conveyor 7 is used for conveying boxes 10 and is electrically connected to an external control device. Figure 5 As shown, a guide rail 75 is provided on the frame of the box conveying mechanism 7. Two parallel inverted T-shaped grooves are provided on the guide rail 75. Both inverted T-shaped grooves extend along the conveying direction of the box conveying mechanism 7. The bottom of the mounting base of the box position detection sensor 73 is installed on the inverted T-shaped groove by fasteners, so that the position of the box position detection sensor 73 on the box conveying mechanism 7 can be adjusted along the conveying direction of the box conveying mechanism 7. The box position detection sensor 73 is a photoelectric sensor. The box position detection sensor 73 is used to detect whether there is a box 10 at the boxing position. The box position detection sensor 73 is electrically connected to an external control device.

[0058] like Figure 2and Figure 5 As shown, the box positioning baffle 8 is vertically and flexibly installed between the gaps of two adjacent rollers of the stainless steel roller conveyor belt. The box baffle bracket 81 is fixedly installed below the box conveying mechanism 7. The upper end of the lifting guide column 82 is fixedly connected to the box positioning baffle 8, and the lower part of the lifting guide column 82 is slidably installed on the box baffle bracket 81. The cylinder body of the box baffle lifting cylinder 83 is fixedly installed on the box baffle bracket 81. The output end of the box baffle lifting cylinder 83 faces upward and is connected to the box positioning baffle 8. The solenoid valve of the box baffle lifting cylinder 83 is electrically connected to an external control device.

[0059] like Figure 5 As shown, a pair of guardrails 71 are symmetrically arranged on the frame of the box conveying mechanism 7. Both guardrails 71 extend along the conveying direction of the box conveying mechanism 7 and are used to guide the box 10 to move along a preset track. Each guardrail 71 is adjustablely mounted on the frame of the box conveying mechanism 7 through multiple guardrail adjusting handles 72 to adjust the spacing between the pair of guardrails 71, thereby meeting the conveying requirements of boxes 10 of different sizes and specifications. The base of the guardrail adjusting handle 72 is fixedly connected to the frame of the box conveying mechanism 7. The adjusting rod of the guardrail adjusting handle 72 passes through the through hole on the base, and one end of the adjusting rod of the guardrail adjusting handle 72 is fixedly connected to the guardrail 71. The set screw of the guardrail adjusting handle 72 is threadedly connected to the base, and the inner end of the set screw extends into the through hole on the base and presses against the adjusting rod.

[0060] A pre-storage box top mechanism 74 is mounted on the box conveying mechanism 7 to limit the position of boxes 10 located upstream of the packing position, so as to transport boxes 10 one by one to the packing position. Preferably, the pre-storage box top mechanism 74 includes a top plate 741, a top cylinder 742, and a pre-storage box position detection sensor 743. The bottom of the mounting base of the top cylinder 742 is mounted on the inverted T-slot of the guide rail 75 by fasteners, so that the position of the top cylinder 742 on the box conveying mechanism 7 can be adjusted along the conveying direction of the box conveying mechanism 7. The output end of the top cylinder 742 is fixedly connected to the top plate 741, which is used to drive the top plate 741 to press against one side of the box 10, thereby limiting the position of the box 10 with the cooperation of the guardrail 71 on the other side of the box 10. The solenoid valve of the top box cylinder 742 is electrically connected to an external control device. The bottom of the mounting base of the pre-storage box position detection sensor 743 is mounted on the inverted T-slot of the guide rail 75 by fasteners, so that the position of the pre-storage box position detection sensor 743 on the box conveying mechanism 7 can be adjusted along the conveying direction of the box conveying mechanism 7. The pre-storage box position detection sensor 743 adopts a photoelectric sensor and is used to detect whether there is a box 10 at the top plate 741. The pre-storage box position detection sensor 743 is electrically connected to an external control device.

[0061] The external control device is a programmable logic controller (PLC).

[0062] The working process of this utility model's automatic liquid bag packing device is as follows: The bag conveying mechanism 4 transports the filled liquid bags to a pair of unloading platforms 3 in an inclined position. After the bag conveying detection sensor 41 detects that a liquid bag has been transported to the pair of unloading platforms 3, the bag conveying mechanism 4 stops, and the liquid bags on the unloading platforms 3 move downwards on the unloading platforms 3 under the action of gravity, in conjunction with the unpowered rollers, until they abut against the limit baffle 9. At this time, the bag arrival detection sensor 31 detects that there is a liquid bag at the predetermined position, and then the output ends of a pair of lifting cylinders 61 retract simultaneously, causing the pair of unloading platforms to stop. Platform 3 switches from an inclined position to a horizontal position; simultaneously, the extended end of the top box cylinder 742 retracts, causing the empty box 10 upstream of the packing position to move under the transport of the box conveyor 7. Then, the first of these empty boxes 10 is stopped at the packing position by the box positioning baffle 8. At this time, the box position detection sensor 73 detects that there is a box 10 at the packing position. When the second box 10 moves to the top plate 741, the pre-stored box position detection sensor 743 detects that there is a box 10 at the top plate 741. Subsequently, the extended end of the top box cylinder 742 extends, causing the top plate 741 to press against the box 10. 0, to prevent the box 10 from continuing to move to the packing position; after the output ends of a pair of lifting cylinders 61 retract, when the box position detection sensor 73 detects that there is a box 10 at the packing position, the output end of the unloading cylinder 51 extends to open a pair of unloading platforms 3, and the liquid bag falls accurately into the box 10 under the guidance of the bag dropping auxiliary funnel 54. Then the output end of the box baffle lifting cylinder 83 retracts, causing the box positioning baffle 8 to move down and no longer block the box 10 that has been packed. The box conveying mechanism 7 transports the box 10 that has been packed to the subsequent process. After the box position detection sensor 73 detects that there is no box 10 at the packing position, the box baffle... The output end of the lifting cylinder 83 extends, causing the box positioning baffle 8 to move upward and reset. At the same time, the extension end of the top box cylinder 742 retracts, causing the empty box 10 upstream of the boxing position to move under the conveying of the box conveying mechanism 7. After the liquid bag falls into the box 10, the output end of the box baffle lifting cylinder 83 retracts, and the output end of the unloading cylinder 51 extends, causing a pair of unloading platforms 3 to close. The output ends of a pair of lifting cylinders 61 extend simultaneously, causing a pair of unloading platforms 3 to switch from a horizontal position to an inclined position. After the pair of unloading platforms 3 are switched to the inclined position, the bag conveying mechanism 4 operates to convey the liquid bag to the unloading platform 3.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the specific technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
