Description

Technical Field

[0001] This application relates to the field of pharmaceutical filling and processing technology, and more specifically, to an oral liquid filling meter. Background Technology

[0002] In the production process of oral liquids, accurate filling and metering are crucial to ensuring product quality and dosage accuracy. Traditional oral liquid filling methods rely on manual labor or simple mechanical devices, which are easily affected by factors such as liquid viscosity, temperature, and container shape, resulting in inaccurate filling volume and difficulty in meeting high-precision dosage requirements. During the filling process, it is impossible to monitor whether the empty bottles are qualified in real time, and unqualified empty bottles need to be manually removed. If the weight after filling does not meet the standard, unqualified products are likely to enter the next process, increasing quality risks and production costs. In view of this, we propose an oral liquid filling meter. Utility Model Content

[0003] 1. Technical problems to be solved The purpose of this application is to provide an oral liquid filling meter that solves the technical problems mentioned in the background art. It achieves accurate filling and dual weight detection of oral liquids through the cooperation of a flow filling pump and a weighing meter, ensuring that the filling amount of each bottle meets the standard and the error is controlled within a very small range. The weighing meter can detect in real time whether the empty bottle is qualified and whether the weight after filling meets the requirements. Combined with the rejection material discharge mechanism, it automatically rejects unqualified bottles, preventing defective products from entering the next process, improving product quality, and realizing the technical effect of automated material distribution, filling and rejection of medicine bottles, reducing manual intervention and improving production efficiency.

[0004] 2. Technical Solution This application provides an oral liquid filling meter, comprising: The Y-shaped guide frame is integrally fixedly connected to a semi-circular plate. The semi-circular plate is provided with a semi-circular groove and an arc-shaped discharge port. The Y-shaped guide frame is equipped with a feeding conveyor belt mechanism, a discharging conveyor belt mechanism, and a rejecting conveyor belt mechanism. A distributing motor is fixedly installed in the middle of the Y-shaped guide frame. The output shaft of the distributing motor is fixedly connected to a distributing disc for conveying multiple medicine bottles placed on the feeding conveyor belt mechanism and the discharging conveyor belt mechanism at equal intervals along an arc path. A filling and metering mechanism, comprising a flow filling pump and a connected filling pipe, wherein the flow filling pump is fixedly connected to an L-shaped frame, the L-shaped frame is fixedly located at the middle edge of a semi-circular plate, and the filling pipe is located above a medicine bottle; The weighing device comprises two weighing devices, each including an electronic weighing device and a top column. The electronic weighing device is fixedly installed on the bottom surface of a semi-circular plate by screws. The top column is slidably sleeved with the semi-circular plate. A top rod is fixedly provided at the bottom end of the top column. An L-shaped plate is fixedly connected to the bottom end of the electronic weighing device. A touch switch is fixedly installed on the L-shaped plate. The top rod elastically presses against the touch switch. The material rejection and discharge mechanism includes a support assembly fixedly installed on a semi-circular plate. A first electric cylinder and a second electric cylinder are fixedly installed on the support assembly. The piston rod of the first electric cylinder is fixedly connected to an arc-shaped push block, and the piston rod of the second electric cylinder is fixedly connected to an arc-shaped stop block. The arc-shaped stop block is embedded in the arc-shaped discharge port.

[0005] By adopting the above technical solution, an infeed conveyor belt mechanism, an outfeed conveyor belt mechanism, and a rejection conveyor belt mechanism are installed on the Y-shaped guide frame. Empty medicine bottles for oral liquid filling are conveyed into the Y-shaped guide frame by the infeed conveyor belt mechanism and piled up at the distribution plate. The distribution motor drives the distribution plate to rotate, conveying the medicine bottles at equal intervals along an arc path to the filling station at the bottom of the flow filling pump. During the medicine bottle conveying process, the empty medicine bottles first pass through the first weighing meter position, using the medicine bottle to hold the top rod. When there is other liquid inside the medicine bottle, it will make the top rod elastic. The pressure-sensitive switch triggers an alarm, then the piston rod of the second electric cylinder retracts, causing the arc-shaped stop to move upward. The piston rod of the first electric cylinder extends and retracts once, using the arc-shaped pusher to push the defective empty medicine bottles onto the rejection conveyor belt mechanism, thus achieving the purpose of automatically rejecting defective empty medicine bottles. After the empty medicine bottles enter the filling area, their weight is measured a second time after filling, and the system automatically determines whether the filled medicine bottles meet the requirements, preventing defective products from entering the next process, improving product quality, and realizing the automated material distribution, filling and rejection of medicine bottles, reducing manual intervention and improving production efficiency.

[0006] Optionally, the Y-shaped guide frame is provided with a feeding guide groove, a discharging guide groove and a rejection guide groove, which are respectively used to install the feeding conveyor belt mechanism, the discharging conveyor belt mechanism and the rejection conveyor belt mechanism. The feeding guide groove and the discharging guide groove are located on the same horizontal conveyor line and are respectively located on both sides of the material distribution motor.

[0007] By adopting the above technical solution, the feeding guide chute and the discharging guide chute are set on the same horizontal conveyor line, which facilitates the smooth conveying of bottles. In addition, the rejection guide chute is matched with the arc-shaped discharge port to ensure that unqualified medicine bottles can be accurately rejected and enter the rejection conveyor belt mechanism.

[0008] Optionally, the semicircular plate is provided with an insertion hole at the bottom of the filling tube and at the arc-shaped discharge port, and the two insertion holes are located on the same arc line, and a top column is inserted into each insertion hole.

[0009] By adopting the above technical solution, the design of the top column facilitates the weighing and measuring device to detect the weight of the medicine bottle, while avoiding interference with the filling process. The two top columns are set on the same arc, so the medicine bottles conveyed by the dispensing plate will pass through the two top columns in sequence, thereby achieving the purpose of dual weighing and detection.

[0010] Optionally, a spring is installed on the outer sleeve of the top rod, and the spring is located between the measuring plate of the electronic weighing device and the top column.

[0011] By adopting the above technical solution, the weight of the medicine bottle presses down on the top column, which forces the spring to deform. The spring elastically presses down on the measuring plate of the electronic weighing device, so that the weight of the medicine bottle can be measured by the measuring plate of the electronic weighing device. By setting a standard range for the weight of empty medicine bottles, if the weight of an empty medicine bottle exceeds the set value, the top rod at the bottom of the top column presses against the touch switch to trigger an alarm. The rejection material discharge mechanism pushes the unqualified medicine bottle into the rejection material conveyor belt mechanism.

[0012] Optionally, the support assembly includes a concave frame and an L-shaped seat, the concave frame and the L-shaped seat intersecting perpendicularly and being fixedly connected, the first electric cylinder being fixedly installed on the L-shaped seat, and the second electric cylinder being fixedly installed on the concave frame.

[0013] By adopting the above technical solution, the first electric cylinder is horizontally installed on the L-shaped seat, and the second electric cylinder is vertically fixed on the concave frame. The piston rod extension line of the first electric cylinder and the piston rod extension line of the second electric cylinder are perpendicularly intersected, so that the unqualified medicine bottles can be accurately pushed into the rejection conveyor belt mechanism.

[0014] Optionally, the dispensing disc is provided with multiple arc grooves along its circumference that match the medicine bottle, and the dispensing disc rotates in contact with the inner wall of the semicircular groove of the semicircular plate.

[0015] By adopting the above technical solution, the close rotation of the dispensing disc and the semi-circular groove reduces friction and noise, improves the stability of the equipment operation, and the design of the semi-circular groove ensures the stability of the medicine bottle during the dispensing process, preventing the medicine bottle from tipping over or slipping.

[0016] Optionally, the two touch switches form a dual-control switch structure and are connected to the flow filling pump via a microprocessor.

[0017] By adopting the above technical solutions, the dual-control switch structure improves the reliability of the touch switch and avoids misjudgment caused by the failure of a single switch. The communication connection between the microprocessor and the flow filling pump realizes intelligent control of the filling process, ensuring the accuracy and stability of the filling volume. Moreover, when the filling fails the weight test, the bottle number, weight, detection time and other information can be recorded in the system for easy traceability and analysis.

[0018] 3. Beneficial effects One or more technical solutions provided in this application have at least the following technical effects or advantages: 1. By combining a flow-through filling pump and a weighing device, precise filling and dual weight detection of oral liquids are achieved, ensuring that the filling volume of each bottle meets the standard and the error is controlled within a very small range; 2.

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1 to 4 This application provides an oral liquid filling meter, comprising: Y-shaped guide frame 1, Y-shaped guide frame 1 is integrally fixedly connected with semi-circular plate 9, semi-circular groove 91 and arc-shaped discharge port 92 are provided on semi-circular plate 9, Y-shaped guide frame 1 is equipped with feeding conveyor belt mechanism 2, discharging conveyor belt mechanism 3 and rejecting conveyor belt mechanism 4, Y-shaped guide frame 1 is fixedly installed with a material distribution motor 61 at the middle position of Y-shaped guide frame 1, the output shaft of material distribution motor 61 is fixedly connected with material distribution plate 6, for conveying multiple medicine bottles 5 placed on feeding conveyor belt mechanism 2 and discharging conveyor belt mechanism 3 along the arc path at equal intervals; The filling and metering mechanism 8 includes a flow filling pump 81 and a connected filling pipe 82. The flow filling pump 81 is fixedly connected to an L-shaped frame 83, which is fixedly located at the middle edge of the semi-circular plate 9. The filling pipe 82 is located above a medicine bottle 5. Weighing device 10, there are two weighing devices 10, each weighing device 10 includes an electronic weighing device 101 and a top column 102. The electronic weighing device 101 is fixedly installed on the bottom surface of the semi-circular plate 9 by screws. The top column 102 is slidably sleeved with the semi-circular plate 9. A top rod 1021 is fixedly provided at the bottom end of the top column 102. An L-shaped plate 104 is fixedly connected to the bottom end of the electronic weighing device 101. A touch switch 105 is fixedly installed on the L-shaped plate 104. The top rod 1021 elastically presses against the touch switch 105. The rejecting material discharge mechanism 7 includes a support assembly fixedly mounted on a semi-circular plate 9. A first electric cylinder 73 and a second electric cylinder 75 are fixedly mounted on the support assembly. The piston rod of the first electric cylinder 73 is fixedly connected to an arc-shaped push block 74, and the piston rod of the second electric cylinder 75 is fixedly connected to an arc-shaped stop block 76. The arc-shaped stop block 76 is embedded in the arc-shaped discharge port 92. An infeed conveyor belt mechanism 2, an outfeed conveyor belt mechanism 3, and a rejecting material conveyor belt mechanism 4 are mounted on a Y-shaped guide frame 1. Empty medicine bottles 5 for oral liquid filling are conveyed into the Y-shaped guide frame 1 via the infeed conveyor belt mechanism 2 and accumulate at the distribution plate 6. The distribution motor 61 drives the distribution plate 6 to rotate, conveying the medicine bottles 5 along an arc path at equal intervals to the filling station at the bottom of the flow filling pump 81. During the conveying process of the medicine bottles 5... Empty medicine bottles 5 first pass through the first weighing device 10. The bottle 5 presses against the top post 102. When other liquids are present inside the bottle 5, the top post 1021 elastically presses against the touch switch 105 to trigger an alarm. Then, the piston rod of the second electric cylinder 75 retracts, causing the arc-shaped stop block 76 to move upwards. The piston rod of the first electric cylinder 73 extends and retracts once, using the arc-shaped pusher block 74 to push the defective empty medicine bottles 5 onto the rejection conveyor belt mechanism 4. This achieves the automated rejection of defective empty medicine bottles 5. The empty medicine bottles 5 entering the filling area undergo a second weight measurement after filling, automatically determining whether the filled medicine bottles 5 meet the requirements. This prevents defective products from entering the next process, improving product quality. The automated dispensing, filling, and rejection of medicine bottles 5 reduces manual intervention and improves production efficiency.

[0022] Reference Figure 1 and Figure 2 The Y-shaped guide frame 1 is equipped with a feeding guide trough, a discharging guide trough, and a rejection guide trough, which are used to install the feeding conveyor belt mechanism 2, the discharging conveyor belt mechanism 3, and the rejection conveyor belt mechanism 4, respectively. The feeding guide trough and the discharging guide trough are located on the same horizontal conveying line and are located on both sides of the distributing motor 61. The feeding guide trough and the discharging guide trough are located on the same horizontal conveying line to facilitate the smooth conveying of bottles. The rejection guide trough cooperates with the arc-shaped discharge port 92 to ensure that unqualified medicine bottles 5 can be accurately rejected and enter the rejection conveyor belt mechanism 4.

[0023] Reference Figure 3 and Figure 4 The semi-circular plate 9 has an insertion hole at the bottom of the filling tube 82 and at the arc-shaped discharge port 92, and the two insertion holes are located on the same arc. A top post 102 is inserted into each insertion hole. The design of the top post 102 facilitates the weighing and measuring device 10 to detect the weight of the medicine bottle 5, while avoiding interference with the filling process. The two top posts 102 are located on the same arc, so the medicine bottle 5 conveyed by the distributing plate 6 will pass through the two top posts 102 in sequence, thereby achieving the purpose of dual weighing and detection.

[0024] Reference Figure 3 and Figure 4 A spring 103 is installed on the outer sleeve of the top rod 1021, and the spring 103 is located between the measuring plate of the electronic weighing device 101 and the top column 102. The weight of the medicine bottle 5 presses the top column 102, and the top column 102 forces the spring 103 to deform. The spring 103 elastically presses the measuring plate of the electronic weighing device 101, so that the weight of the medicine bottle 5 can be measured through the measuring plate of the electronic weighing device 101. By setting a standard range for the weight of the empty medicine bottle 5, if the weight of the empty medicine bottle 5 exceeds the set value, the top rod 1021 at the bottom of the top column 102 presses against the touch switch 105 to trigger an alarm. The rejection material discharge mechanism 7 pushes the unqualified medicine bottle 5 into the rejection material conveyor belt mechanism 4.

[0025] Reference Figure 3 and Figure 4 The support assembly includes a concave frame 71 and an L-shaped seat 72, which intersect perpendicularly and are fixedly connected. A first electric cylinder 73 is fixedly installed on the L-shaped seat 72, and a second electric cylinder 75 is fixedly installed on the concave frame 71. The first electric cylinder 73 is horizontally installed on the L-shaped seat 72, and the second electric cylinder 75 is vertically fixedly installed on the concave frame 71. The piston rod extension line of the first electric cylinder 73 and the piston rod extension line of the second electric cylinder 75 are perpendicularly intersected, so that the unqualified medicine bottle 5 can be accurately pushed into the rejection conveyor belt mechanism 4.

[0026] Reference Figure 1 and Figure 2The dispensing plate 6 has multiple arc grooves along its circumference that match the medicine bottle 5. The dispensing plate 6 rotates in contact with the inner wall of the semicircular groove 91 of the semicircular plate 9. The contact rotation between the dispensing plate 6 and the semicircular groove 91 reduces friction and noise, and improves the stability of the equipment. The design of the semicircular groove 91 ensures the stability of the medicine bottle 5 during the dispensing process and prevents the medicine bottle 5 from tipping over or slipping.

[0027] Reference Figure 3 and Figure 4 Two pressure switches 105 form a dual-control switch structure and are connected to the flow filling pump 81 via a microprocessor. The dual-control switch structure improves the reliability of the pressure switches 105 and avoids misjudgment caused by the failure of a single switch. The communication connection between the microprocessor and the flow filling pump 81 realizes intelligent control of the filling process, ensuring the accuracy and stability of the filling volume. When the filling fails the weight test, the number, weight, and detection time of the medicine bottle 5 can be recorded in the system for easy traceability and analysis.

[0028] Working principle: Empty medicine bottles 5 are conveyed by the feed conveyor belt mechanism 2 into the distribution station near the distribution plate 6 on the Y-shaped guide frame 1. The distribution motor 61 drives the distribution plate 6 to rotate along the inner wall of the semi-circular groove 91 of the semi-circular plate 9, distributing the empty medicine bottles 5 evenly to the filling station at the bottom of the flow filling pump 81 along an arc path. When any empty medicine bottle 5 enters the arc-shaped discharge port 92, the first weight test is performed. The weight of the medicine bottle 5 presses down on the top column 10. 2. The top column 102 forces the spring 103 to deform, and the spring 103 elastically presses the measuring plate of the electronic weighing device 101, thereby measuring the weight of the medicine bottle 5 through the measuring plate of the electronic weighing device 101. By setting a standard range for the weight of the empty medicine bottle 5, if the weight of the empty medicine bottle 5 exceeds the set value, the top rod 1021 at the bottom of the top column 102 presses against the touch switch 105 to trigger an alarm. The piston rod of the second electric cylinder 75 retracts, causing the arc-shaped stop block 76 to move upward. The first electric cylinder 73... The piston rod extends and retracts once, using the arc-shaped pusher 74 to push the unqualified empty medicine bottle 5 onto the rejection conveyor belt mechanism 4, achieving the purpose of automatically rejecting the unqualified empty medicine bottle 5, avoiding manual intervention and improving efficiency. After the empty medicine bottle 5 continues to be transported to the filling station, the flow filling pump 81 performs quantitative filling of the qualified empty medicine bottle 5 through the filling pipe 82. The filling amount is controlled by the parameters of the flow filling pump 81 (such as time and flow rate). After filling is completed, the electronic weighing device 101 measures the total weight of the filled medicine bottle 5 to achieve secondary weighing. The cooperation between the flow filling pump 81 and the electronic weighing device 101 achieves high-precision filling and measurement. If the deviation between the actual filling amount and the preset value is within the allowable range, it is judged as a qualified product and enters the discharge process. If the filling amount is abnormal, it is judged as an unqualified product, triggering an alarm and recording information such as the number, weight, and detection time of the medicine bottle 5 in the system for subsequent traceability and analysis.
