DETAILED DESCRIPTION

[0024] The utility model will be further explained in detail through the drawings and the specific embodiment.

[0025] EMBODIMENT

[0026] Please refer to the reference. Figures 1 to 3 This embodiment provides a bubble control structure for a decoction packaging machine, including a turntable 110, an origin signal sensor 120, and a drug injection solenoid valve 130. The turntable 110 is coaxially connected to the lower hot-cutting shaft 210 of the packaging machine head. The turntable 110 has a notch 111. The origin signal sensor 120 includes a signal transmitter and a signal receiver. The signal transmitter and the signal receiver are respectively disposed on both sides of the notch 111 of the turntable 110. The drug injection solenoid valve 130 is installed on the injection pipe 100. The drug injection solenoid valve 130 is connected to the origin signal sensor 120.

[0027] In this embodiment of the decoction packaging machine's bubble control structure, the signal transmitter and receiver of the origin signal sensor 120 are respectively located on both sides of the notch 111 of the turntable 110. That is, the signal transmitter and receiver are located on the circumference of the notch 111 as the turntable 110 and the lower hot-cutting shaft 210 rotate. When the notch 111 rotates to the position of the signal transmitter and receiver, the notch 111 cannot block the signal transmitted from the signal transmitter to the signal receiver, and at this time the notch 111 is at the origin position; when the notch 111 rotates to other positions, the turntable 110 blocks the signal transmitted from the signal transmitter to the signal receiver.

[0028] The bubble control structure of the decoction packaging machine in this embodiment utilizes the principle of bubble overflow to allow bubbles to escape within a suitable preset time. Specifically, by using a time control method, for example, setting the preset time to 2.5 seconds, the liquid injection is forcibly shut off 2.5 seconds before the packaging bag is heat-sealed. During these 2.5 seconds, the bubbles are allowed to fully escape. Once the packaging bag is heat-sealed, liquid injection can proceed, preventing bubbles from entering the packaging bag.

[0029] When packaging long medicine bags, liquid injection can also be performed while the lower heat-sealing shaft 220 is stopped from heat-sealing the bag. After the lower heat-sealing shaft 220 stops heat-sealing the bag, the liquid injection is forcibly stopped within a preset time before the heat-sealing is restarted, so that the air bubbles can float out within the preset time. That is, after the lower heat-sealing shaft 220 stops heat-sealing the bag, before restarting heat-sealing, the notch 111 rotates to the origin position. The signal receiver receives the signal emitted by the signal transmitter, and the origin signal sensor 120 emits the origin signal to the injection solenoid valve 130, controlling the injection solenoid valve 130 to be forcibly closed, stopping the liquid injection. At this time, the air bubbles in the packaging bag begin to float out. As the notch 111 continues to rotate, it leaves the origin position after a preset time, and the air bubbles float out within the preset time. When the notch 111 leaves the origin position, the lower heat-sealing shaft 220 is restarted to heat-seal the bag.

[0030] As can be seen, the bubble control structure of the decoction packaging machine in this embodiment utilizes the time interval between the stop and restart of the heat sealing of the bag by the lower heat sealing shaft 220, and sets this time interval as the preset time for the bubbles to float out; within this preset time, the injection solenoid valve 130 is forcibly closed by connecting the signal of the origin signal sensor 120, so that the bubbles float out within the preset time, and then the heat sealing of the bag by the lower heat sealing shaft 220 is resumed.

[0031] It should be noted that the bubble control structure of the decoction packaging machine in this embodiment allows bubbles to automatically float out within a preset time due to the different densities of liquid and gas. That is, the gas and liquid separate naturally without the need for external force.

[0032] The filling can be set to stop after the notch 111 rotates with the turntable 110 and begins to enter the origin position; then, after the turntable 110 rotates 90°, it heat-seals the packaging bag; the time for the turntable 110 to rotate one revolution can be set to 8.4 seconds. That is, within the 8.4 seconds of the turntable 110 rotating one revolution, 2.5 seconds are used to expel air bubbles and 5.9 seconds are used for heat sealing the packaging.

[0033] Specifically, the notch 111 is located at the edge of the turntable 110, which facilitates processing and allows the notch 111 to rotate with the turntable 110 and the lower hot cutting shaft 210 to reach or leave the position between the signal transmitter and the signal receiver.

[0034] Specifically, the origin signal sensor 120 and the injection solenoid valve 130 are respectively connected to the controller. The controller can activate the origin signal sensor 120, causing the signal transmitter to send a signal to the signal receiver. The controller can receive the origin signal from the origin signal sensor 120 when the notch 111 rotates to the origin position, and send a forced closure signal to the injection solenoid valve 130, causing the injection solenoid valve 130 to close forcibly to stop the injection. This improves control efficiency and control effect.

[0035] Specifically, a pair of lower hot cutting shafts 210 are provided, one of which is coaxially connected to the turntable 110, which facilitates the coaxial installation of the turntable 110 and the lower hot cutting shaft 210 and helps to avoid interference with the operation of the lower hot cutting shaft 210.

[0036] Specifically, the packaging machine head includes a pair of side plates 240, a pair of lower heat-cutting shafts 210, a pair of lower heat-sealing shafts 220 and a pair of upper longitudinal pressure heat-sealing shafts 230 arranged from bottom to top and rotatably mounted between the pair of side plates 240. The packaging machine head can adopt existing technology products.

[0037] Please refer to the reference. Figures 1 to 4Specifically, the lower heat sealing shaft 220 is connected to the rotation output shaft of the lower shaft motor 250, and the lower shaft motor 250 is connected to a controller, so that the controller can control the lower shaft motor 250 to drive the lower heat sealing shaft 220 to rotate.

[0038] like Figure 5 As shown, the lower shaft motor 250 drives one of the lower heat sealing shafts 220 to rotate, and the lower heat sealing shaft 220 drives the other lower heat sealing shaft 220 to rotate through a gear transmission mechanism; the other lower heat sealing shaft 220 drives a lower heat cutting shaft 210 to rotate through a gear transmission mechanism, and the lower heat cutting shaft 210 drives the other lower heat cutting shaft 210 to rotate through a gear transmission mechanism.

[0039] For example, a pair of lower heat-sealing shafts 220 includes a first lower heat-sealing shaft 221 and a second heat-sealing shaft 222, and a pair of lower heat-cutting shafts 210 includes a first lower heat-cutting shaft 211 and a second lower heat-cutting shaft 212. The rotation output shaft of the lower shaft motor 250 is coaxially connected to the first lower heat-sealing shaft 221. The first lower heat-sealing shaft 221 is coaxially connected to the first gear 301. The first gear 301 meshes with the second gear 302. The second gear 302 is coaxially connected to the second lower heat-sealing shaft 222. The second gear 302 meshes with the third gear 303. The third gear 303 meshes with the fourth gear 304. The fourth gear 304 is coaxially connected to the first lower heat-cutting shaft 211. The fourth gear 304 meshes with the fifth gear 305. The fifth gear 305 is coaxially connected to the second lower heat-cutting shaft 212.

[0040] Specifically, the upper longitudinal pressure heat sealing shaft 230 of the packaging machine head is connected to the rotation output shaft of the upper shaft motor 260, and the upper shaft motor 210 is connected to the controller, so that the upper shaft motor 260 can be controlled by the controller to drive the upper longitudinal pressure heat sealing shaft 230 to rotate.

[0041] The upper shaft motor 260 drives one of the upper longitudinal pressure heat sealing shafts 230 to rotate, and the upper longitudinal pressure heat sealing shaft 230 drives the other upper longitudinal pressure heat sealing shaft 230 to rotate through a gear transmission mechanism.

[0042] For example, a pair of upper longitudinal pressure heat sealing shafts 230 includes a first upper longitudinal pressure heat sealing shaft 231 and a second upper longitudinal pressure heat sealing shaft 232. The rotation output shaft of the upper shaft motor 260 is coaxially connected to the first upper longitudinal pressure heat sealing shaft 231, the first upper longitudinal pressure heat sealing shaft 231 is coaxially connected to the sixth gear 306, the sixth gear 306 meshes with the seventh gear 307, and the seventh gear 307 is coaxially connected to the second upper longitudinal pressure heat sealing shaft 232.

[0043] It should be noted that, Figure 5 To illustrate the structure of each gear transmission mechanism, the upper shaft motor 260 and the lower shaft motor 250 are omitted from the display.

[0044] Please refer to the reference. Figures 1 to 4Specifically, the origin signal sensor 120 uses an infrared transmitter and receiver integrated photoelectric switch, which can be a product based on existing technology.

[0045] The injection solenoid valve 130 can be a fast-acting valve powered by a 220V coil, which offers high force, rapid action, minimal impact from liquid viscosity, and a smooth opening and closing mechanism. The injection solenoid valve 130 can utilize existing technology.

[0046] The lower shaft motor 250, the upper shaft motor 210, and the controller can all be mounted on the packaging machine head, for example, on the side plate 240. The two side plates 240 are configured as parallel rectangular plates.

[0047] Turntable 110 is configured as a circular disc. When turntable 110 rotates with the lower hot cutting shaft 210, it does not contact the packaging machine head to avoid interfering with the operation of the packaging machine head.

[0048] The notch 111 is rectangular for ease of processing. The injection tube 100 is positioned above the packaging machine head.

[0049] The lower heat-sealing shaft 220 is configured as a lower horizontal heat-sealing shaft structure, and its outer wall is provided with a horizontal sealing side; the lower heat-cutting shaft 210 is configured as a lower horizontal cutting shaft structure, and its outer wall is provided with a horizontal cutting side; a 125° included angle is provided between the horizontal sealing side and the horizontal cutting side.
