Description

Technical Field

[0001] This application relates to the technical field of filling equipment, and in particular to a highly stable two-drive filling device. Background Technology

[0002] Reagents, also known as biochemical reagents or test reagents, are pure chemicals primarily used for chemical reactions, analytical testing, research experiments, teaching experiments, and chemical formulation. In reagent production, reagents are typically packaged in reagent bottles for transportation and sale.

[0003] In related technologies, manufacturers use a filling machine to fill reagents into reagent bottles. The filling machine includes a connecting pipe connected to a storage tank for storing reagents and multiple filling heads connected to the connecting pipe. The filling machine is equipped with a lifting device that raises and lowers the multiple filling heads. A conveyor belt is set below the filling heads, and the reagent bottles flow on the conveyor belt. The lifting device drives the filling heads to rise and fall, allowing the filling heads to extend into the reagent bottles and fill them with reagents. The existing lifting device includes a crossbar on which multiple filling heads are mounted and a cylinder that drives the crossbar to move up and down. The crossbar is set along the length of the conveyor belt, and the multiple filling heads are installed at the bottom of the crossbar. The cylinder is fixed to the filling machine, and the cylinder output shaft is fixed to the middle of the crossbar. When the reagent bottles flow to the bottom of the filling machine, the cylinder drives the crossbar to descend, and the multiple filling heads extend into the reagent bottles to output reagents. After filling is completed, the cylinder drives the crossbar to rise, completing the filling operation.

[0004] Regarding the aforementioned technologies, the crossbar is subjected to the gravity of the filling head at both ends. After prolonged use, the ends of the crossbar will undergo slight bending deformation, causing the filling head installed at both ends of the crossbar to be unable to extend into the reagent bottle during filling, and the filling head will come into contact with the mouth of the reagent bottle. When the filling head outputs reagent, the output part of the filling head is blocked by the mouth of the reagent bottle, resulting in insufficient reagent input into the reagent bottle. On the other hand, when the filling head outputs reagent, the reagent is easily splashed due to the pressure at the mouth of the reagent bottle, which can contaminate nearby equipment. Utility Model Content

[0005] This application provides a highly stable two-drive filling device to solve the problem that the filling heads installed at both ends of the crossbar cannot be inserted into the reagent bottle due to the bending and deformation of both ends of the crossbar.

[0006] This application provides a highly stable two-drive filling device, which adopts the following technical solution: A high-stability two-drive filling device includes multiple filling heads and a crossbar for mounting the filling heads, and a transmission mechanism for driving the crossbar to rise and fall. The transmission mechanism is mounted on a filling machine. The transmission mechanism includes a slide rail, which is mounted on the filling machine and arranged along the direction of the filling head's rise and fall. There are two transmission mechanisms, which are located at both ends of the crossbar, and the slide rails of the two transmission mechanisms are slidably connected to both ends of the crossbar.

[0007] By adopting the above technical solution, when the reagent bottle flows to the filling machine, the transmission mechanism at both ends of the crossbar is activated, and the slide rail drives the crossbar to move downward to carry out the filling operation. By distributing the force through the transmission mechanism at both ends, the two ends of the crossbar are evenly supported, preventing the filling head from being unable to enter the reagent bottle due to bending deformation caused by the weight of the filling head at both ends of the crossbar. This ensures that the reagent can be accurately injected into the reagent bottle and prevents reagent splashing and damage to the filling head or reagent bottle due to misalignment between the filling head and the reagent bottle.

[0008] Preferably, it also includes a protective shell for preventing reagent splashing and contamination of the transmission mechanism. The protective shell is installed on the filling machine, and the slide rail is located inside the protective shell. Two protective shells are provided for each of the two transmission mechanisms, and the two protective shells are located at the two ends of the crossbar, respectively.

[0009] By adopting the above technical solution, reagent splashes during the filling process may seep into the transmission mechanism, causing component corrosion; the protective shell forms a closed space, blocking splashed reagents, protecting the internal transmission structure, and extending the equipment maintenance cycle.

[0010] Preferably, the transmission mechanism further includes a transmission belt and a driving component; the transmission belt is installed on the filling machine and arranged along the lifting direction of the filling head, and the transmission belt is located inside the protective housing; the crossbar is fixed to both the transmission belt and the slide rail; the driving component is installed on the filling machine and located inside the protective housing, the driving component is located at one end of the slide rail and drives the transmission belt to move, and the transmission belt drives the crossbar to slide on the slide rail to perform lifting and lowering actions.

[0011] By adopting the above technical solution, the transmission belt has elastic buffering characteristics, preventing the crossbar from shaking due to instantaneous force fluctuations and ensuring a smooth lifting and lowering process of the filling head; the transmission belt is laid out in the vertical direction, occupying little horizontal space, and is suitable for the limited installation space of the filling machine; the drive component drives the transmission belt to move along the lifting and lowering direction of the filling head, and the transmission belt drives the crossbar to slide on the slide rail to perform lifting and lowering actions.

[0012] Preferably, the crossbar is provided with a connector at its end, the transmission belt has a notch, the connector is located at the notch of the transmission belt and is fixed to the transmission belt; the connector is slidably mounted on the slide rail.

[0013] By adopting the above technical solution, the connector is embedded in the notch of the transmission belt and fixed, so that the crossbar and the transmission belt form a rigid connection, preventing the slippage that may occur in traditional belt drives; the connector also serves as a slider of the slide rail, which not only undertakes the transmission function, but also provides support through the slide rail, preventing the end of the crossbar from bending and deforming due to the weight of the filling head.

[0014] Preferably, a mounting block is fixed to the side of the crossbar near the filling head, and a mounting rod is fixed to the mounting block. The mounting rod is arranged parallel to the lifting direction of the filling head. A slider is provided through the mounting rod, and the filling head is fixedly mounted on the slider. A limiting member is provided at the end of the mounting rod away from the mounting block to prevent the slider from falling off the mounting rod. Multiple sets of the mounting block, slider, mounting rod, and limiting member are provided for multiple filling heads. A sensor for detecting the position of the slider is provided on the crossbar. The sensor and the slider are at different heights. Under normal working conditions, the sensor cannot detect the position of the slider.

[0015] By adopting the above technical solution, when the filling head accidentally misaligns with the reagent bottle and comes into contact with it, the filling head will contact the bottle mouth or body. The filling head will slide along the mounting rod with the slider. After the slider slides along the mounting rod, the sensor will detect the slider and transmit the information to the system. The system will then control the drive to stop working, preventing damage to the reagent bottle or filling head caused by the filling head forcibly contacting the bottle mouth or body.

[0016] Preferably, a spring is sleeved on the mounting rod, and the spring is located between the slider and the limiting member. During the filling process, if the filling head accidentally misaligns with the reagent bottle and comes into contact with the reagent bottle, the slider slides along the mounting rod and the spring is compressed.

[0017] By adopting the above technical solution, when the filling head accidentally misaligns with the reagent bottle and comes into contact with it, the slider slides along the mounting rod. A spring is set to provide buffer force for the slider, preventing the slider from coming into contact with the limiting component due to excessive sliding speed, thus preventing the filling head from making hard contact with the reagent bottle. This also prevents the filling head from being damaged due to hard contact with the bottle mouth or body.

[0018] Preferably, the driving component is a motor, and a reducer is provided between the output shaft of the driving component and the transmission belt to change the output direction of the driving component force. The axis of the output shaft of the driving component is arranged parallel to the lifting direction of the filling head. The driving component converts horizontal rotation into vertical rotation through the reducer to drive the transmission belt to rotate.

[0019] By adopting the above technical solution, the motor output shaft is set along the lifting direction of the filling head, and the horizontal rotation is converted into vertical transmission belt motion through the reducer, which is adapted to the spatial layout of the filling machine and reduces the space occupied by the horizontal installation of the motor.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting transmission mechanisms and slide rails at both ends of the crossbar, the drive at both ends replaces the traditional drive at the middle, which evenly distributes the weight of the crossbar and prevents bending deformation caused by the weight of the filling head at both ends of the crossbar. This ensures that the filling head maintains a horizontal position for a long time, so that the reagent is accurately injected into the reagent bottle, and prevents reagent splashing and damage to the filling head or reagent bottle due to misalignment between the filling head and the reagent bottle. 2. The protective shell provides sealed protection for the transmission mechanism, preventing reagent splashes and protecting components such as the transmission belt and pulleys from reagent corrosion; the spring buffer and slider self-adjusting structure provide cushioning when the filling head accidentally comes into contact with the reagent bottle, preventing hard collisions that could damage the reagent bottle or filling head. 3. By setting up sensors to detect the slider position in real time, the machine will automatically stop when the filling head is misaligned, reducing the cost of manual monitoring and improving the safety and automation of the production line.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail.

[0024] This application discloses a highly stable two-drive filling device.

[0025] refer to Figure 1A highly stable two-drive filling device includes multiple filling heads 1, a crossbar 2 for mounting the filling heads 1, a transmission mechanism 3 for driving the crossbar 2 to rise and fall, and a protective shell 4 for preventing reagent splashing and contamination of the transmission mechanism 3. The multiple filling heads 1 are mounted on the crossbar 2. Two transmission mechanisms 3 are provided, each located at one end of the crossbar 2 and slidably connected to both ends of the crossbar 2, so that the crossbar 2 is set along the height direction, i.e., along the rising and falling direction of the filling heads 1. Two protective shells 4 are also provided on the filling machine, corresponding to the two transmission mechanisms 3, each located at one end of the crossbar 2. The transmission mechanisms 3 are mounted on the filling machine and located inside the protective shells 4.

[0026] refer to Figure 2 and Figure 3 Specifically, the transmission mechanism 3 includes a slide rail 31, a transmission belt 32, and a drive component 35. The slide rail 31 is welded and fixed to the filling machine, and is arranged along the lifting direction of the filling head 1. The transmission belt 32 is installed on the filling machine and is arranged along the lifting direction of the filling head 1, and is located inside the protective shell 4. The end of the crossbar 2 is fixed to the transmission belt 32, and the end of the crossbar 2 is connected to a slide table 311. The slide table 311 slides in cooperation with the slide rail 31. The transmission belt 32 drives the crossbar 2 to rise and fall, while the slide table 311 slides on the slide rail 31. The drive component 35 is fixedly installed on the filling machine by bolts and is located inside the protective shell 4. The drive component 35 is located at one end of the slide rail 31 and drives the transmission belt 32 to move. The transmission belt 32 drives the crossbar 2 to slide on the slide rail 31 to perform lifting and lowering actions.

[0027] The filling machine is equipped with a first drive wheel 33 and a second drive wheel 34. The first drive wheel 33 is connected to the drive component 35. Both the first drive wheel 33 and the second drive wheel 34 are rotatably mounted on the filling machine by being sleeved on the rotating shaft. Both the first drive wheel 33 and the second drive wheel 34 are installed inside the protective housing 4. The distance between the two drive wheels is greater than the height of the filling head 1. The length of the slide rail 31 is the same as the distance between the two drive wheels. The drive belt 32 is wrapped around the first drive wheel 33 and the second drive wheel 34 and is arranged along the lifting direction of the filling head 1.

[0028] The driving component 35 is a motor, and the output shaft axis of the driving component 35 is arranged parallel to the lifting direction of the filling head 1. A reducer is provided between the driving component 35 and the first transmission wheel 33. One end of the reducer is connected to the motor output shaft through gear meshing, and the other end of the reducer is welded and fixed to the rotating shaft on the filling machine. The driving component 35 converts the horizontal rotation into vertical rotation through the reducer to drive the first transmission wheel 33 to rotate. The rotation of the first transmission wheel 33 drives the transmission belt 32 to move, which is adapted to the spatial layout of the filling machine and reduces the space occupied by the horizontal installation of the motor.

[0029] refer to Figure 3 and Figure 4Both ends of the crossbar 2 are fixed with connectors 5 by bolts. The transmission belt 32 has a notch. The connector 5 is located at the notch of the transmission belt 32. The connector 5 is fixed to the transmission belt 32 by a fixing plate and bolts passing through the fixing plate and the transmission belt 32. The connector 5 is also fixed to the slide table 311 on the slide rail 31 by bolts so as to slide on the slide rail 31. The driving member 35 drives the first transmission wheel 33 to rotate. The rotation of the first transmission wheel 33 drives the transmission belt 32 to move. The connector 5 moves with the transmission belt 32. At the same time, the connector 5 slides on the slide rail 31 under the action of the transmission belt 32, thereby driving the crossbar 2 to move in the lifting direction of the filling head 1.

[0030] refer to Figure 5 Specifically, a mounting block 6 is bolted to the side of the crossbar 2 near the filling head 1. A mounting rod 7, a cylindrical rod, is threaded through and fixed to the mounting block 6. A slider 8 and a spring 9 are sleeved on the mounting rod 7, allowing the mounting rod 7 to slide relative to the slider 8. A limiter 10 is bolted to the end of the mounting rod 7, and the spring 9 is located between the slider 8 and the limiter 10. The filling head 1 passes through the slider 8 and is threaded through and fixed to the slider 8. The mounting block 6, slider 8, and other components are also threaded through and fixed to the slider 8. The mounting rod 7 and the limiting member 10 are provided in multiple sets for multiple filling heads 1. During the filling process of the filling head 1 moving downward, if the filling head 1 is accidentally misaligned with the reagent bottle and comes into contact with the reagent bottle, the slider 8 will slide along the mounting rod 7. At this time, the spring 9 is compressed, which plays a buffering role and prevents the slider 8 from coming into contact with the limiting member 10 due to the excessive sliding speed of the slider 8, thereby preventing the filling head 1 from making hard contact with the reagent bottle. This prevents the reagent bottle or the filling head 1 from being damaged due to the hard contact between the filling head 1 and the bottle mouth or bottle body.

[0031] A sensor 11 for detecting the position of slider 8 is bolted to the end of the crossbar 2. In this embodiment, the sensor 11 is a laser sensor 11. The sensor 11 and slider 8 are at different heights. Under normal working conditions, the sensor 11 cannot detect the position of slider 8. When slider 8 slides up along the mounting rod 7 due to the obstruction of filling head 1, the sensor 11 detects slider 8 and sends a signal to the control system. Subsequently, the control system stops the drive component 35.

[0032] The implementation principle of this embodiment is as follows: When the reagent bottle flows to the filling machine, the drive component 35 works to make the first transmission wheel 33 rotate, which in turn drives the transmission belt 32 to start moving. The connecting component 5 moves with the transmission belt 32, which drives the crossbar 2 to move downward, so that the filling head 1 extends into the reagent bottle to perform the filling operation. During the downward movement of the filling head 1, if the filling head 1 accidentally misaligns with the reagent bottle and comes into contact with it, the slider 8 will slide along the mounting rod 7. At this time, the spring 9 is compressed, which plays a buffering role and prevents the slider 8 from coming into contact with the limiting component 10 due to the excessive sliding speed of the slider 8, which would cause the filling head 1 to make hard contact with the reagent bottle. This prevents the filling head 1 from being damaged due to hard contact with the bottle mouth or bottle body. The sensor 11 detects the slider 8 and sends a signal to the control system. Subsequently, the control system stops the drive component 35 and prevents the transmission mechanism 3 from continuing to work, which would cause the filling head 1 to make rigid contact with the reagent bottle and damage the filling head 1 or the reagent bottle.

[0033] In summary, by distributing the force through the transmission mechanisms 3 at both ends, the crossbar 2 is evenly supported at both ends, preventing bending deformation caused by the weight of the filling head 1 at both ends of the crossbar 2. This ensures that the filling head 1 remains horizontally positioned for a long time, allowing the reagent to be accurately injected into the reagent bottle. At the same time, the filling head 1 slides on the mounting rod 7 via the slider 8, and a sensor 11 is set to detect the position of the slider 8. This prevents reagent splashing and damage to the filling head 1 or the reagent bottle due to accidental misalignment between the filling head 1 and the reagent bottle, which could result in rigid contact.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
