Description

Technical Field

[0001] This utility model relates to the field of veterinary drug production equipment technology, specifically to a liquid veterinary drug production quantitative filling equipment. Background Technology

[0002] Currently, in the veterinary drug production process, the final processing of liquid veterinary drugs is usually filling. To ensure processing efficiency, the mature injection-type filling machine is often used. This machine uses a cylinder to drive a piston to extract and eject the material, a one-way valve to control the material flow, and a magnetic reed switch to control the stroke of the cylinder, thus adjusting the filling volume to meet the packaging requirements for quantitative filling.

[0003] However, in actual production, some packaged products filled by long-used plunger filling machines showed some weight differences. After further disassembly and research, the applicant found that this was caused by significant wear of the internal components of the reed switch that indirectly controls the filling volume. It is evident that if only the above-mentioned single technical solution is used to control the filling flow, the reliability will become unstable during long-term use.

[0004] Secondly, in order to understand the filling status in real time, the existing technology usually adopts manual sampling inspection. Although this method can achieve the purpose, it is inevitable that time and labor costs will increase. Therefore, in view of the multiple problems existing in the above-mentioned existing technology, the applicant will provide a liquid veterinary drug production quantitative filling equipment to solve the problem. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quantitative filling device for liquid veterinary drug production, which solves the problems mentioned in the background.

[0006] This utility model provides the following technical solution: a liquid veterinary drug production quantitative filling equipment, including a filling platform, a packaging bottle, a filling mechanism set on the top of the filling platform, and a hopper. The front end of the filling mechanism is provided with a filling output pipe for filling, and the top of the filling output pipe is provided with an electronic flow meter and a displacement sensor.

[0007] The top of the filling platform is fitted with a support frame, and both sides of the support frame are fitted with drive rollers. Conveyor belts are fitted between the front ends of the two drive rollers and between the rear ends of the two drive rollers. One end of one drive roller is connected to a servo motor installed on the rear end of the support frame. A clearance groove is formed between the two conveyor belts, which is aligned with the filling output pipe.

[0008] The top of the filling platform is provided with a positioning sleeve, a pressure detection rod, and a transmission component. The pressure detection rod is fitted inside the positioning sleeve and can be connected to the output end of the transmission component. The movable structure inside the pressure detection rod is aligned with the filling output pipe and can pass through the clearance groove to perform top pressure detection under the output transmission of the transmission component.

[0009] The preferred pressure-detecting rod includes an inner sleeve and a first return spring. The inner sleeve is snapped into the inside of the positioning sleeve. The first return spring is fitted into the annular clearance space formed by the middle part of the inner sleeve and the inner wall of the positioning sleeve. The two ends of the first return spring are respectively fixed to the middle surface of the inner sleeve and the inner wall of the top of the positioning sleeve.

[0010] Specifically, the first return spring internally houses a pressure sensor, a cross-shaped rod, and a second return spring. The middle part of the cross-shaped rod is engaged with the top inner side of the inner sleeve. The two ends of the second return spring are respectively fixedly installed on the bottom surface of the cross-shaped rod and the inner wall of the top of the inner sleeve. The top end of the cross-shaped rod is fixed to the bottom of the transition baffle. Under the elastic limit of the second return spring, there is a clearance gap between the bottom end of the cross-shaped rod and the pressure sensing surface of the pressure sensor.

[0011] Preferably, the transmission component includes a trapezoidal stop and an electric push rod. The trapezoidal stop serves as the output structure of the transmission component and is connected to the output end of the electric push rod. The bottom structure of the inner sleeve is configured as a hemispherical structure and can make contact with the reciprocating trapezoidal stop.

[0012] Selectedly, the bottom of the positioning sleeve is fixed with an integrated base, the top of the integrated base is installed with a fixed seat between the top of the integrated base and the housing surface of the electric push rod, and the top surface of the integrated base is fixed with a slide rail that engages with the trapezoidal stop.

[0013] The top of the filling platform has a threaded hole, and the interior of the integrated base has a clearance hole aligned with the threaded hole. The integrated base and the top of the filling platform are installed and fixed by means of screws fitting the clearance hole and then screwing them into the threaded hole.

[0014] In particular, the front and rear ends of the top of the support frame are fixed with limiting frames, and a guide groove is formed between the two limiting frames that is aligned with the clearance groove, and the guide groove can be used to move the packaging bottle.

[0015] Ideally, both limiting frames have clearance grooves inside, and there is an anti-interference space between the two limiting frames and any one of the conveyor belts.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model uses a pressure detection device composed of an electronic flow meter, a positioning sleeve, a pressure detection rod, and a transmission component. During the filling process, the electronic flow meter detects the raw material flow in real time. After filling, the transmission component drives the pressure detection rod to perform pressure detection on the bottle. This generates two sets of comparative data. Combined with the original filling data of the filling platform, anomalies can be detected in a timely manner, solving several problems existing in the prior art.

[0018] 2. The pressure testing device provided in this utility model can perform pressure testing on the filled packaging bottles in an independent manner during the batch filling process, thereby replacing sampling inspection and realizing further automation.

[0019] 3. This utility model uses two opposing limiting frames to form a guide groove around the packaging bottle. As the packaging bottle is transported by the two conveyor belts, the guide groove constrains the movement of the packaging bottle. When the bottom of the packaging bottle is subjected to pressure, the two limiting frames can passively support the packaging bottle in a relatively clamping state. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 A liquid veterinary drug production quantitative filling equipment includes a filling platform 1, a packaging bottle 5, a filling mechanism 2 set on the top of the filling platform 1, and a hopper 3. The front end of the filling mechanism 2 is provided with a filling output pipe 4 for filling, and the top of the filling output pipe 4 is provided with an electronic flow meter 6 and a displacement sensor 12.

[0029] The top of the filling platform 1 is fitted with a support frame 7. Both sides of the support frame 7 are fitted with drive rollers 8. Conveyor belts 9 are fitted between the front ends of the two drive rollers 8 and between the rear ends of the two drive rollers 8. One end of one drive roller 8 is connected to a servo motor 10 installed on the rear end of the support frame 7. A clearance groove is formed between the two conveyor belts 9, which is aligned with the filling output pipe 4.

[0030] The top of the filling platform 1 is provided with a positioning sleeve 13, a pressure detection rod 14, and a transmission component 15. The pressure detection rod 14 is fitted inside the positioning sleeve 13 and can be connected to the output end of the transmission component 15. The movable structure inside the pressure detection rod 14 is aligned with the filling output pipe 4 and can pass through the clearance groove to perform top pressure detection under the output transmission of the transmission component 15.

[0031] The pressure sensing rod 14 includes an inner sleeve 141 and a first return spring 142. The inner sleeve 141 is snapped into the inside of the positioning sleeve 13. The first return spring 142 is fitted in the annular clearance space formed by the middle part of the inner sleeve 141 and the inner wall of the positioning sleeve 13. The two ends of the first return spring 142 are respectively fixed to the middle surface of the inner sleeve 141 and the inner wall of the top of the positioning sleeve 13. The pressure sensor 143, the cross-shaped rod 144 and the second return spring 145 are fitted inside the first return spring 142. The middle part of the cross-shaped rod 144 is snapped into the inner side of the top of the inner sleeve 141. The two ends of the second return spring 145 are respectively fixed to the bottom surface of the cross-shaped rod 144 and the inner wall of the top of the inner sleeve 141. The top end of the cross-shaped rod 144 is fixed to the bottom of the transition baffle 146. Under the elastic limit of the second return spring 145, there is a clearance gap between the bottom end of the cross-shaped rod 144 and the pressure sensing surface of the pressure sensor 143.

[0032] The transmission component 15 includes a trapezoidal stop 151 and an electric push rod 152. The trapezoidal stop 151 serves as the output structure of the transmission component 15 and is connected to the output end of the electric push rod 152. The bottom structure of the inner sleeve 141 is set as a hemispherical structure and can make contact with the trapezoidal stop 151 that moves back and forth.

[0033] In specific implementation: the servo motor 10 is turned on and its output drives the corresponding transmission roller 8 to rotate synchronously. Then, with the support of the support frame 7 and the cooperation of another transmission roller 8, the two conveyor belts 9 rotate synchronously inside the support frame 7 as the two transmission rollers 8 rotate and are driven by friction. Next, the packaging bottle 5 is placed on the top left side of the two conveyor belts 9. Then, with the synchronous conveying operation of the two conveyor belts 9, the packaging bottle 5 will gradually move towards the bottom of the filling output pipe 4. After the packaging bottle 5 is aligned with the filling output pipe 4, the displacement sensor 12 will also output relevant data to the existing background equipment due to the obstruction of the edge structure of the packaging bottle 5, indicating that the packaging bottle 5 has arrived in place, and the servo motor 10 is temporarily turned off.

[0034] The filling mechanism 2 is activated, and the filling mechanism 2 automatically injects the liquid raw material inside the hopper 3 into the packaging bottle 5 through the filling output pipe 4. During the injection process, the electronic flow meter 6 will detect the filling volume in real time and transmit the relevant data to the existing back-end equipment to provide comparison data, provide operators with data comparison conditions, and promptly detect abnormalities.

[0035] After the filling of the packaging bottle 5 is completed, for further verification, the electric push rod 152 can be activated. The output end of the electric push rod 152 drives the trapezoidal stop 151, which then gradually presses against the inner sleeve 141. Subsequently, the inner sleeve 141 moves upward automatically under the guidance of the positioning sleeve 13. At the same time, the transition baffle 146 inside the inner sleeve 141 is released after it reaches the filled packaging bottle 5. Due to the obstruction of the packaging bottle 5, it moves downward and applies pressure to the pressure sensor 143. After the electric push rod 152 completes a single transmission stroke, the maximum value of the data transmitted by the pressure sensor 143 is collected and compared with the initial standard value. If the difference is within the tolerance, it indicates that the quantitative filling is completed well. If the difference is not within the tolerance, it indicates that the quantitative filling is incorrect and timely maintenance intervention is required.

[0036] Please see Figure 4 An integrated base 17 is fixed to the bottom of the positioning sleeve 13. A fixed seat is installed between the top of the integrated base 17 and the housing surface of the electric push rod 152. A slide rail 16 that engages with the trapezoidal stop block 151 is fixed to the top surface of the integrated base 17. A threaded hole is opened on the top of the filling platform 1. A clearance hole aligned with the threaded hole is opened inside the integrated base 17. The integrated base 17 and the top of the filling platform 1 are installed and fixed by screwing the clearance hole and then screwing it into the threaded hole.

[0037] In specific implementation: Considering the replacement and maintenance of the pressure testing rod 14 and the transmission component 15, the integrated base 17 is set as the integrated installation condition for the positioning sleeve 13, the pressure testing rod 14 and the transmission component 15. In the future, if any component of the positioning sleeve 13, the pressure testing rod 14 and the transmission component 15 fails, modular replacement can be achieved by simply removing the screws between the integrated base 17 and the filling platform 1.

[0038] Please see Figure 6 The front and rear ends of the top of the support frame 7 are fixed with limit frames 11, and a guide groove is formed between the two limit frames 11 that is aligned with the clearance groove. The guide groove can be moved and fitted with the packaging bottle 5. The interior of the two limit frames 11 is provided with clearance grooves, and there is an anti-interference space between the two limit frames 11 and any one of the conveyor belts 9.

[0039] In specific implementation: Considering the problem of decreased stability at the bottom of the bottle 5 after filling, a guide groove is formed around the bottle 5 by two relatively set limiting frames 11. During the subsequent transmission of the bottle 5 with the two conveyor belts 9, the guide groove constrains the movement of the bottle 5. When the bottom of the bottle 5 is subjected to pressure, the two limiting frames 11 can passively support the bottle 5 in a relatively clamping state.
