Description

Technical Field

[0001] The utility model relates to a bag-supporting system for plant beverages. Background Art

[0002] In recent years, many functional botanical beverages have been packaged in small-dose bags for easy portability and quantitative drinking. These bagged botanical beverages are typically automatically filled and packaged using bag-feeding packaging machines, such as the one disclosed in utility model patent publication number CN216375243U. However, the bag-opening system of this bag-feeding packaging machine primarily uses a plug inserted into the bag to blow air to open it. Some botanical beverages, for example, have a narrowed opening at the top for easier drinking, such as the one disclosed in design patent publication number CN306458729S. The opening of these unusually shaped bags is susceptible to bending and deformation when the plug is inserted, compromising subsequent filling and packaging operations. Utility Model Content

[0003] The present utility model provides a bag-holding system for herbal beverages, comprising a turntable, the periphery of which is provided with multiple sets of clamps for holding the packaging bag, the clamps being equidistantly spaced about the axis of the turntable. The packaging bag comprises a bag body, a neck having an inner diameter smaller than the bag body, and a bag opening disposed on the neck. The bag-holding system further comprises an upper bag-holding mechanism for holding open the bag opening and a lower bag-holding mechanism for holding open the bag body.

[0004] The upper bag-supporting mechanism is installed on a cantilever, and the upper bag-supporting mechanism includes two bag-supporting pendulums rotatably installed on the cantilever; the lower ends of the two bag-supporting pendulums are respectively fixed with pendulum pieces for inserting into the bag opening of the packaging bag clamped by the clamp and opening the bag opening of the packaging bag; the rotation axes of the two bag-supporting pendulums are parallel and the rotation directions are opposite so that the two pendulum pieces can approach or move away from each other.

[0005] The lower bag-holding mechanism includes a plug, which can be raised and lowered along the axis of the turntable to push out or insert the packaging bag with the bag opening opened; the plug is provided with an air blowing port for blowing air into the packaging bag to hold the bag body open; the air blowing port is connected to an air blowing pipeline for conveying air flow to the air blowing port.

[0006] The bag-holding system of the present invention comprises an upper bag-holding mechanism and a lower bag-holding mechanism, wherein the upper bag-holding mechanism inserts and holds open the bag opening of the packaging bag through the swing pieces of two bag-holding swing pieces. Since the swing pieces are sheet-shaped, they are easy to insert into the bag opening of the packaging bag. After the swing pieces hold open the bag opening, the plug of the lower bag-holding mechanism enters the packaging bag through the opened bag opening to blow air and hold open the bag body, so that the packaging bag is fully opened. This process is not likely to cause creases on the bag opening; and it is convenient for subsequent filling to the set capacity. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The present application is further described below with reference to the accompanying drawings:

[0016] See attached Figure 1-8 A bag-holding system for plant-based beverages includes a turntable 1, and a plurality of clamps 11 for clamping packaging bags 6 are provided on the periphery of the turntable 1, and the clamps 11 are axially evenly distributed around the axis of the turntable 1; the packaging bag 6 includes a bag body 61, a neck 62 with an inner diameter smaller than the bag body 61, and a bag opening 63 provided on the neck 62.

[0017] The bag-opening system further includes an upper bag-opening mechanism 2 for opening the bag opening 63 of the packaging bag 6 and a lower bag-opening mechanism 3 for opening the bag body 61 of the packaging bag 6 .

[0018] The upper bag-supporting mechanism 2 is mounted on a cantilever 4, and the upper bag-supporting mechanism 2 includes two bag-supporting pendulums 21 rotatably mounted on the cantilever 4; the lower ends of the two bag-supporting pendulums 21 are respectively fixed with pendulum pieces 22 for inserting into the bag opening 63 of the packaging bag 6 clamped by the clamp 11 and opening the bag opening 63 of the packaging bag 6; the rotation axes of the two bag-supporting pendulums 21 are parallel and the rotation directions are opposite so that the two pendulum pieces 22 can approach each other for easy insertion into the bag opening 63 of the packaging bag 6 or move away from each other to open the bag opening 63.

[0019] The lower bag-opening mechanism 3 includes a plug 31, which can be raised and lowered along the axis of the turntable 1 to push out or insert the packaging bag 6 with the bag opening 63 opened; the plug 31 is provided with an air blowing port 311 for blowing air into the packaging bag 6 to open the bag body 61 of the packaging bag 6; the air blowing port 311 is connected to an air blowing pipeline for conveying air flow to the air blowing port 311.

[0020] The bag-holding system of the present technical solution includes an upper bag-holding mechanism 2 and a lower bag-holding mechanism 3, wherein the upper bag-holding mechanism 2 inserts and holds open the bag opening 63 of the packaging bag 6 through the swing pieces 22 of the two bag-holding swing members 21. Since the swing pieces 22 are sheet-shaped, they are easy to insert into the bag opening 63 of the packaging bag 6. After the swing pieces 22 hold open the bag opening 63, the plug 31 of the lower bag-holding mechanism 3 enters the packaging bag 6 through the opened bag opening 63 to blow air to hold open the bag body 61, so that the packaging bag 6 is fully opened. This process is not likely to cause creases on the bag opening 63; and it is convenient for subsequent filling to the set capacity.

[0021] The upper bag-supporting mechanism 2 further includes a toggle member 23 and a spring 24 .

[0022] The middle part of the bag-supporting ornament 21 is rotatably connected to the cantilever 4, and a trigger portion 211 is provided on the bag-supporting ornament 21; a toggle member 23 is provided with a toggle rod 231, and the trigger portions 21 of the two bag-supporting ornaments 21 both rest on the toggle rod 231; the toggle member 23 is rotatably mounted on the cantilever 4 so that the toggle rod 231 can move up and down, and the trigger portion 211 is toggled to drive the bag-supporting ornament 21 to rotate.

[0023] The spring 24 is located between the two bag-supporting ornaments 21, and the two ends of the spring 24 are respectively connected to the upper ends of the two bag-supporting ornaments 21 so that the upper ends of the two bag-supporting ornaments 21 tend to move closer to each other. When the upper ends of the two bag-supporting ornaments 21 move closer to each other, the lower ends of the two bag-supporting ornaments 21 rotate upward to move the two pendulum pieces 22 away from each other.

[0024] In this embodiment, three rotating shafts 41 are provided on the cantilever 4, and shaft holes are provided on the bag-supporting ornament 21 and the toggle member 23. Each shaft hole is respectively sleeved on the rotating shaft 41 at the corresponding position.

[0025] The triggering parts 211 of the two bag-supporting ornaments 21 are arranged on opposite sides thereof.

[0026] Both ends of the spring 24 are provided with hanging ears 241 , and the upper end of the bag-supporting ornament 21 is provided with a connecting post 212 , and the hanging ears 241 are hung on the connecting post 212 .

[0027] The lower end of the bag-supporting pendulum 21 is provided with a connecting rod 213 extending along the direction of its rotation axis. The pendulum piece is fixed to the extended end of the connecting rod 213 to make room above the pendulum piece for the plug 31 to move.

[0028] The two bag-supporting ornaments 21 of the present technical solution are driven to rotate by the triggering portion 211 driven by the lever 231 and are reset in linkage with the spring 24 to ensure the synchronization of the activities of the bag-supporting ornaments 21.

[0029] The upper bag-supporting mechanism 2 also includes an upper bag-supporting cylinder 25 for driving the toggle member 23 to rotate. The toggle member 23 includes two toggle arms 232 extending radially along its rotation axis. The toggle rod 231 is mounted on one of the toggle arms 232, while the other toggle arm 232 is affixed to the piston rod of the upper bag-supporting cylinder 25. The cylinder body of the upper bag-supporting cylinder 25 is mounted on the cantilever 4. In this embodiment, the upper bag-supporting cylinder 25 is arranged at an angle, with the distal end of the cylinder body of the upper bag-supporting cylinder 25 fixed to the cantilever 4.

[0030] The toggle member 23 of the present technical solution rotates under the drive of the piston rod of the upper bag-supporting cylinder 25 , and can resist the pulling force of the spring 24 , thereby ensuring the tension and speed of the swing piece 22 being expanded.

[0031] The upper bag-supporting mechanism 2 also includes a limiter 26 ; the limiter 26 is fixed on the cantilever 4 , and a travel hole 261 is provided on the limiter 26 , and the travel hole 261 extends around the rotation axis of the toggle member 23 ; the toggle rod 231 is inserted into the travel hole 261 and moves along the travel hole 261 .

[0032] The range of movement of the lever 231 of the present technical solution is limited by the travel hole 261 , which also limits the rotation range of the bag-supporting ornament 21 , thereby preventing the bag-supporting ornament 21 from excessively rotating and damaging the pendulum 22 .

[0033] The lower bag-supporting mechanism 3 further includes a lower bag-supporting cylinder 32 for driving the plug 31 to move up and down;

[0034] The cylinder body of the lower bag-supporting cylinder 32 is fixedly mounted on a support frame 5 , and the plug 31 is fixedly mounted on the piston rod of the lower bag-supporting cylinder 32 .

[0035] The clamp 11 is clamped on the bag body 61 of the packaging bag 6, and the bag opening 63 of the packaging bag 6 extends from the top surface of its neck 62 to the left and right sides, so that the bag opening 63 remains slightly open to facilitate the insertion of the flap 22.

[0036] When using, Figure 1As shown, the initial state of the upper bag-supporting mechanism 2 is that the two pendulum pieces 22 are close to each other. The turntable 1 rotates to move the packaging bag 6 on the clamp 11 to the pendulum piece 22, and the pendulum piece 22 is inserted into the bag opening 63 from the side. The upper bag-supporting cylinder 25 drives the toggle piece 23 to rotate downward. The upper ends of the two bag-supporting pendulum pieces 21 move closer to each other under the action of the spring 24, causing the two pendulum pieces 22 to move away from each other to open the bag opening 63. The lower bag-supporting mechanism 3 is located above the pendulum piece 22. Driven by the lower bag-supporting cylinder 32, the plug 31 moves downward to be inserted into the packaging bag 6 through the opened bag opening 63, and blows air to open the bag body 61. Figure 2 As shown. The plug 31 then moves upward to remove the packaging bag 6, and the filling operation begins. After the packaging bag 6 is filled, the upper bag-supporting cylinder 25 drives the toggle member 23 upward, lifting the trigger portion 211. This in turn causes the upper ends of the two bag-supporting swing members 21 to rotate away from each other, while the lower ends of the bag-supporting swing members 21 rotate toward each other, returning the two swinging pieces 22 to their initial positions. Driven by the turntable 1, the packaging bag 6 is transferred to the next step (sealing the bag opening).

[0037] The above preferred embodiments should be regarded as examples of the implementation methods of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on it should be regarded as within the scope of protection of this patent.
