Description

Technical Field

[0001] This utility model relates to a liquid or solid-liquid mixture filling device, specifically a translational aseptic capping filling device. Background Technology

[0002] Bag-in-box packaging is a special but commonly used form of packaging, widely used for products such as juice, water, pesticides, and food additives. It has advantages such as convenient storage and transportation, and reduced transportation costs.

Traditional filling equipment usually employs a separate structure, meaning these three processes are performed by different machines. This results in a large floor space, low efficiency, and problems such as susceptibility to contamination during the filling process and significant errors in bag opening positioning. Although rotary filling equipment has emerged, enabling continuous operation, its complex structure and high maintenance costs remain significant. Utility Model Content

Detailed Implementation

[0037] To make the objectives, advantages and features of this utility model clearer, the following describes in further detail a translational aseptic capping and filling device proposed by this utility model in conjunction with the accompanying drawings and specific embodiments.

[0038] In the description of this utility model, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Reference Figure 1 This utility model discloses a translational aseptic capping and filling device, including an aseptic chamber support 1, a lower slide plate 2, an aseptic chamber 3, an upper slide plate 4, a cap-pressing and cap-pulling mechanism 6, a cap-pressing and cap-pulling lifting mechanism 7, a filling mechanism 8, a filling lifting mechanism 9, an aseptic chamber drive mechanism, a limit cylinder 13, a limit column 14, a first connecting plate 15, and a controller.

[0040] like Figure 1 and Figure 2 As shown, the sterile chamber support 1 includes a left support and a right support. The two ends of the sliding plate 2 are respectively fixed to the tops of the left and right supports. A sterile chamber 3 is fixed below the sliding plate 2, located between the left and right supports. The sterile chamber 3 is equipped with a bag-clamping mechanism 5 and has a steam inlet. Steam is introduced into the sterile chamber 3 through the steam inlet to create positive pressure, preventing bacteria from entering the sterile chamber 3 and thus creating a sterile environment within the sterile chamber 3. Figure 2 and Figure 4 As shown, the bag clamping mechanism 5 includes a pair of bag clamping cylinders 51 and a pair of bag clamping openings 52. The bottom plate of the sterile chamber 3 is provided with an inlet hole for the bag opening to enter. The pair of bag clamping openings 52 are slidably disposed on the bottom plate of the sterile chamber 3 and located on the left and right sides of the inlet hole. The cylinder bodies of the pair of bag clamping cylinders 51 are fixedly disposed on the left and right sides of the sterile chamber 3. The piston rods of the pair of bag clamping cylinders 51 extend into the sterile chamber 3 and are fixedly connected to one bag clamping opening 52.

[0041] like Figure 2 and Figure 3 As shown, the lower surface of the upper slide plate 4 contacts the upper surface of the lower slide plate 2. The present invention provides a translational aseptic capping and filling device, which also includes four L-shaped guide grooves 12. Two L-shaped guide grooves 12 are fixed on the front side of the lower slide plate 2, and the other two L-shaped guide grooves 12 are fixed on the rear side of the lower slide plate 2. The front and rear sides of the upper slide plate 4 are respectively slidably engaged with the two L-shaped guide grooves 12, so that the upper slide plate 4 can move left and right on the lower slide plate 2 along the four L-shaped guide grooves 12.

[0042] The drive end of the sterile chamber drive mechanism is connected to the upper slide plate 4, used to move the upper slide plate 4 left and right on the lower slide plate 2. Specifically, as shown... Figure 1 and Figure 2 As shown, the sterile chamber drive mechanism includes a pair of sterile chamber moving cylinders 10. The cylinder bodies of the pair of sterile chamber moving cylinders 10 are respectively fixed to the top of the left and right supports and located on the left and right sides of the upper slide plate 4, respectively. The piston rods of the pair of sterile chamber moving cylinders 10 are both fixedly connected to the upper slide plate 4. Setting two sterile chamber moving cylinders 10 can improve the stability and reliability of the sterile chamber drive mechanism.

[0043] To limit the left and right movement range of the upper skateboard 4, such as Figure 1 and Figure 2 As shown, the present invention provides a translational aseptic capping and filling device, which further includes four limiting bolts 11. Two limiting bolts 11 are threadedly connected to two protrusions on the top of the left support and located on the left side of the upper slide plate 4, and are spaced apart in the front-back direction. The other two limiting bolts 11 are threadedly connected to two protrusions on the right support and located on the right side of the upper slide plate 4, and are spaced apart in the front-back direction. The axes of the four limiting bolts 11 all extend in the left-right direction.

[0044] like Figure 1 and Figure 2 As shown, the cap-pulling mechanism 6 includes a cap-pulling body 64, a claw cylinder 61, a pressure head 63, a connecting rod, three grippers 62, and three connecting plates. The middle part of the cap-pulling body 64 is fixedly connected to the first connecting plate 15. The lower part of the cap-pulling body 64 passes through the through hole on the upper sliding plate 4 and the strip-shaped clearance hole on the lower sliding plate 2 and extends into the sterile chamber 3. The connecting rod is slidably disposed inside the cap-pulling body 64. The cylinder body of the claw cylinder 61 is fixedly disposed on the top of the cap-pulling body 64, and the lower end of the piston rod of the claw cylinder 61 is connected to the upper end of the connecting rod. The pressure head 63 is fixedly disposed on the lower end of the cap-pulling body 64. The upper end of each gripper 62 is hinged to the lower part of the cap-pulling body 64, and the gripper heads of the three grippers 62 are evenly distributed around the pressure head 63. One end of each of the three connecting plates is hinged to the lower end of the connecting rod, and the other end of each of the three connecting plates is hinged to the upper middle part of the three grippers 62. When the piston rod of the claw cylinder 61 extends, the piston rod of the claw cylinder 61 drives the connecting rod to move downward, and the connecting rod opens the three grippers 62 through the three connecting plates; when the piston rod of the claw cylinder 61 retracts, the piston rod of the claw cylinder 61 drives the connecting rod to move upward, and the connecting rod closes the three grippers 62 through the three connecting plates.

[0045] like Figure 2 and Figure 3 As shown, the cap lifting mechanism 7 includes two guide sleeves 72, two guide posts 73, and two cap lifting cylinders 71. The two guide posts 73 are fixedly connected to the top of the upper slide plate 4, and the two guide sleeves 72 are fixedly connected to the bottom of the first connecting plate 15. The two guide sleeves 72 are slidably sleeved on the two guide posts 73 respectively. The first connecting plate 15 is provided with two through holes through which the guide posts 73 can pass. The cylinder bodies of the two cap lifting cylinders 71 are fixedly connected to the top of the first connecting plate 15 and symmetrically arranged on the front and rear sides of the cap lifting body 64. The piston rods of the two cap lifting cylinders 71 are both set downward and are fixedly connected to the upper slide plate 4 after passing through the first connecting plate 15.

[0046] The cylinder body of the limiting cylinder 13 is fixed to the top of the first connecting plate 15. The piston rod of the limiting cylinder 13 is set downward and connected to the limiting post 14. When the pressing and pulling cover cylinder 71 drives the pressing and pulling cover mechanism 6 to move downward through the first connecting plate 15, the piston rod of the limiting cylinder 13 extends and drives the limiting post 14 to move downward. During the downward movement of the pressing and pulling cover mechanism 6, if the lower end of the limiting post 14 contacts the upper surface of the upper slide plate 4, the pressing and pulling cover mechanism 6 cannot continue to move downward due to the restriction of the limiting cylinder 13 and the limiting post 14, thereby avoiding the pressing and pulling cover mechanism 6 from crushing the cover.

[0047] like Figure 2As shown, the filling mechanism 8 is located on the right side of the cap-pulling mechanism 6. The filling mechanism 8 includes a filling tube, a piston valve, and a valve stem cylinder 81. The filling tube is fixed below the second connecting plate 91 of the filling lifting mechanism 9. The lower end of the filling tube passes through the through hole on the upper sliding plate 4 and the strip-shaped clearance hole on the lower sliding plate 2 in sequence before extending into the sterile chamber 3. A filling head 82 is provided at the lower end of the filling tube. The cylinder body of the valve stem cylinder 81 is fixed at the top of the second connecting plate 91. The piston valve is located on the filling tube, and the valve stem of the piston valve is connected to the piston rod of the valve stem cylinder 81. When the piston rod of the valve stem cylinder 81 retracts, the piston rod of the valve stem cylinder 81 drives the piston valve to move upward, causing the filling head 82 to open. When the piston rod of the valve stem cylinder 81 extends, the piston rod of the valve stem cylinder 81 drives the piston valve to move downward, and the piston valve blocks the filling head 82.

[0048] The filling lifting mechanism 9 also includes two filling lifting cylinders 92. The cylinder bodies of the two filling lifting cylinders 92 are fixed on the top of the upper slide plate 4 and are symmetrically arranged on the front and rear sides of the filling mechanism 8. The upper ends of the piston rods of the two filling lifting cylinders 92 are fixedly connected to the second connecting plate 91.

[0049] The controller is a programmable logic controller (PLC). The solenoid valves of the limit cylinder 13, the claw cylinder 61, the valve stem cylinder 81, the two cap-pulling cylinders 71, the two filling lifting cylinders 92, the pair of bag-clamping cylinders 51, and the pair of sterile room moving cylinders 10 are all electrically connected to the PLC.

[0050] The working process of this utility model's translational aseptic capping and filling device is as follows: Initially, the piston rods of a pair of bag-clamping cylinders 51 extend simultaneously, pushing a pair of bag-clamping cylinders 52 to clamp the bag opening. At this time, the cap-pressing mechanism 6 is directly facing the bag opening. Subsequently, the piston rods of the two cap-pressing cylinders 71 retract simultaneously, driving the cap-pressing mechanism 6 downward through the first connecting plate 15. Simultaneously, as the piston rods of the cap-pressing cylinders 71 retract, the piston rod of the limiting cylinder 13 extends, causing the limiting post 14 to move downward, and the piston rod of the claw cylinder 61 extends, opening the three grippers 62. After the cap-pressing mechanism 6 moves to the preset position, the claw cylinder 6... The piston rod of cylinder 1 retracts, causing the three grippers 62 to close and clamp onto the cap. Then, the piston rods of the two cap-pulling cylinders 71 extend simultaneously, moving the cap-pulling mechanism 6 upwards to remove the cap from the bag opening. Simultaneously, the piston rod of the limiting cylinder 13 retracts. After cap removal, the piston rods of a pair of sterile chamber moving cylinders 10 push the upper slide plate 4 to the left, causing the cap-pulling mechanism 6 and the filling mechanism 8 to move synchronously to the left, aligning the filling head 82 of the filling mechanism 8 with the bag opening. Then, the piston rods of the two filling lifting cylinders 92 retract simultaneously, causing the filling mechanism 8 to move downwards. The filling head 82 is inserted into the bag opening. Then, the piston rod of the valve stem cylinder 81 retracts, opening the filling head 82 and initiating filling. After filling, the piston rod of the valve stem cylinder 81 extends, blocking the filling head 82 with a piston valve. Then, the piston rods of the two filling lifting cylinders 92 simultaneously extend, moving the filling mechanism 8 upwards. Next, the piston rods of a pair of sterile chamber moving cylinders 10 push the upper slide plate 4 to the right, causing the cap-pulling mechanism 6 and the filling mechanism 8 to move synchronously to the right, aligning the cap-pulling mechanism 6 with the bag opening. Then, the piston rods of the two cap-pulling cylinders 71 simultaneously retract, moving the cap-pulling mechanism 6 downwards, and the cap is pulled out. As the piston rod of cylinder 71 retracts, the piston rod of limiting cylinder 13 extends, causing limiting post 14 to move downward. During the downward movement of the cap-pulling mechanism 6, the pressure head 63 presses the cap tightly onto the bag opening. Then, the piston rod of claw cylinder 61 extends, causing the three grippers 62 to open. Subsequently, the piston rods of the two cap-pulling cylinders 71 extend simultaneously, causing the cap-pulling mechanism 6 to move upward. As the piston rod of cap-pulling cylinder 71 extends, the piston rod of limiting cylinder 13 retracts. Then, the piston rod of claw cylinder 61 retracts, and finally, the piston rods of the last pair of bag-closing cylinders 51 retract simultaneously, causing the bag to fall under the influence of gravity.

[0051] This utility model discloses a translational aseptic capping and filling device, which completes the capping, filling and sealing actions sequentially through translation, reducing positioning errors and improving production efficiency. It is also compact, efficient and stable, and has precise control, making it suitable for integrated capping, filling and sealing operations of bag-in-box. At the same time, by setting a limiting cylinder 13 and a limiting post 14, the downward movement distance of the cap-pressing and capping mechanism 6 can be limited, which can prevent the cap-pressing and capping mechanism 6 from damaging the cap.

[0052] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of this utility model.
