Description

Technical Field

[0001] This utility model relates to the field of auxiliary production equipment technology, and in particular to a desiccant filling and compaction device. Background Technology

[0002] In the braking system of subway trains, desiccant, as a key component of the dryer within valve parts, undergoes a complex assembly process, and its assembly quality directly affects the operational safety of the vehicle. Traditional assembly methods have several drawbacks: firstly, they rely on manual labor to move the desiccant barrels between different workstations, requiring multiple loading and weighing to precisely control the desiccant weight. This prevents excessive desiccant from being crushed during subsequent compaction, or insufficient desiccant from causing the cover to collapse. This process demands extremely high precision in desiccant weight measurement. Secondly, in the compaction area, multiple people take turns using rubber mallets to extensively tap around the desiccant barrel, often hundreds or even thousands of times, to ensure the desiccant is properly compacted and meets quality requirements. With the continuous expansion of the subway network, the number of dryers to be assembled has increased dramatically, making this manual weighing and compaction method inefficient. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide a desiccant filling and compaction device, which has the advantages of being able to quantitatively feed the desiccant and automatically compact it, thereby effectively improving the production efficiency of the dryer.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A desiccant filling and compaction device, comprising:

[0006] A conveying mechanism is used to drive the drying drum pallet to move;

[0007] A quantitative feeding mechanism is provided on one side of the conveying mechanism. The quantitative feeding mechanism is used to convey a quantitative amount of desiccant into the drying barrel, wherein the drying barrel is located on the drying barrel support plate.

[0008] A hopper is located on one side of the quantitative feeding mechanism and is connected to the quantitative feeding mechanism;

[0009] A compaction mechanism is disposed below and passes through the conveying mechanism;

[0010] A controller is mounted on the conveying mechanism, and the conveying mechanism, the quantitative feeding mechanism, the hopper, and the controller are all electrically connected to the controller.

[0011] Compared with existing technologies, this application achieves automated filling and compaction of desiccant through the coordinated operation of a feeding mechanism, a quantitative feeding mechanism, a hopper, a vibration mechanism, and a controller. This effectively improves production efficiency, reduces manual operation, lowers production costs, and ensures the accuracy and consistency of desiccant filling.

[0012] As a preferred embodiment of this utility model, the conveying mechanism includes:

[0013] A conveyor frame, on which a double-speed chain and a drive assembly for driving the double-speed chain are provided, and the drying drum tray is located above the double-speed chain;

[0014] A limiting component is disposed on the conveyor frame and electrically connected to the controller.

[0015] The above-described solution, through the cooperation of the double-speed chain and drive components, enables the drying drum pallet to move quickly and stably, improving conveying efficiency. Simultaneously, the limit components ensure that the drying drum pallet stops at designated positions, facilitating subsequent desiccant filling and compaction operations.

[0016] As a preferred embodiment of this utility model, the limiting component includes:

[0017] Limit switch, wherein the limit switch is disposed on the conveyor frame;

[0018] A limiting member is provided on the conveyor frame and is used to restrict the movement of the drying drum tray;

[0019] The limit switch and the limit device are both electrically connected to the controller.

[0020] By employing the above-described scheme, and through the combined use of limit switches and limit devices, precise control of the position of the drying drum pallet is achieved. The limit switches detect the position of the drying drum pallet and transmit the signal to the controller. The controller then controls the movement of the limit devices based on the signal, thereby ensuring that the drying drum pallet stops at the designated position, improving the accuracy of desiccant filling and compaction.

[0021] As a preferred embodiment of this utility model, the quantitative feeding mechanism includes:

[0022] A feeding rack is provided with a dust cover. The dust cover has an installation cavity and an opening on its bottom wall, which is connected to the installation cavity.

[0023] A pressure sensor is disposed in the mounting cavity and connected to the unloading rack, and the pressure sensor is electrically connected to the controller;

[0024] A weighing chamber is provided, which is disposed in the mounting cavity and connected to the pressure sensor. The weighing chamber has a weighing cavity, and a weighing outlet is provided on the bottom wall of the weighing chamber. The weighing outlet is connected to the weighing cavity, and a movable plate is provided in the weighing chamber corresponding to the weighing outlet.

[0025] A feeding funnel is provided below the weighing bin and connected to the feeding frame. The opening on the top wall of the feeding funnel corresponds to the position of the weighing outlet.

[0026] By employing the above-described scheme and combining a pressure sensor with a weighing chamber, precise control of the desiccant dosage is achieved. The dust cover effectively prevents dust and other impurities from entering the weighing chamber, ensuring the purity of the desiccant. The feeding funnel ensures that the desiccant falls accurately and smoothly into the drying container.

[0027] As a preferred embodiment of this utility model, the quantitative feeding mechanism includes a dust suction component, which is disposed on the dust cover and communicates with the mounting cavity.

[0030] The silo body has a material filling port on its top wall and a cover plate corresponding to the material filling port.

[0031] A vacuum feeder is installed on the bottom wall of the hopper. The feed inlet of the vacuum feeder is connected to the hopper, and the discharge outlet of the vacuum feeder is connected to the quantitative feeding mechanism through a feeding pipe. The vacuum feeder is electrically connected to the controller.

[0032] By adopting the above scheme, a vacuum feeder is connected to a quantitative feeding mechanism, which realizes automatic feeding of desiccant and improves feeding efficiency.

[0033] As a preferred embodiment of this utility model, the vibration compaction mechanism includes:

[0034] A base, on which a lifting assembly is provided;

[0035] A vibration assembly is disposed above and connected to the lifting assembly;

[0036] The lifting assembly and the vibration assembly are both electrically connected to the controller.

[0037] The above-described solution, employing a combination of lifting and vibrating components, achieves the compaction of the desiccant within the drying drum. The lifting component adjusts the height of the vibrating component, allowing it to lift the drying drum pallet from the chain conveyor, preventing damage to the chain during compaction. The vibrating component generates vibration through a vibrator, ensuring even distribution and compaction of the desiccant within the drying drum, effectively improving the compaction efficiency.

[0038] As a preferred embodiment of this utility model, the lifting assembly includes:

[0039] A screw jack, wherein the screw jack is mounted on the top wall of the base and is electrically connected to the controller;

[0040] A lifting platform is provided above the screw jack, and the lifting head of the screw jack is connected to the bottom wall of the lifting platform.

[0041] The bottom wall of the lifting platform is provided with a limiting post, and the base is provided with a limiting through hole corresponding to the limiting post. One end of the limiting post is connected to the lifting platform, and the other end passes through the limiting through hole.

[0042] By adopting the above-mentioned scheme and using a screw jack as the lifting component, the advantages of the screw jack in terms of smooth lifting and high lifting accuracy can be fully utilized. Secondly, by setting limit columns and limit through holes, the stability of the lifting platform during the lifting process can be ensured, preventing the lifting platform from shaking and deviating during the lifting process, thereby improving the accuracy of the vibration compaction operation.

[0046] By adopting the above-described solution and installing shock-absorbing supports between the vibration platform and the lifting assembly, the impact of vibration on the lifting assembly and other components can be effectively reduced, thus improving the stability and durability of the device. The vibrator ensures that the vibration platform generates sufficient vibration to ensure the desiccant is evenly distributed and compacted within the drying drum.

[0047] As a preferred embodiment of this utility model, the top wall of the vibration platform is provided with a limit block.

[0048] By adopting the above solution, the limiting block can effectively restrict the movement of the drying drum pallet during the compaction process, prevent the drying drum from tipping over due to the offset of the drying drum pallet, and improve the safety and stability of the compaction operation.

[0049] The above-mentioned desiccant filling and compaction device has the following beneficial effects:

[0050] Through the automated and coordinated operation of the conveying mechanism, quantitative feeding mechanism, hopper, compaction mechanism and controller, the entire process of desiccant filling and compaction is automated, which significantly improves production efficiency, reduces labor costs and operational errors, and ensures accurate desiccant filling. At the same time, the compaction mechanism, through the precise coordination of lifting and vibration components, ensures that the desiccant is evenly distributed in the drying barrel, improving the drying effect. Furthermore, the design of limiting components, dust collection components and shock-absorbing support components further enhances the stability, safety and durability of the equipment operation.

[0060] This utility model proposes a desiccant filling and compaction device.

[0061] Reference Figure 1In one embodiment of this utility model, a desiccant filling and compaction device includes: a conveying mechanism 1, a quantitative feeding mechanism 4, a hopper 5, a compaction mechanism 6, and a controller 7. The conveying mechanism 1 is used to drive the drying barrel pallet 3 to move. The quantitative feeding mechanism 4 is disposed on one side of the conveying mechanism 1 and is used to convey a quantitative amount of desiccant into the drying barrel, wherein the drying barrel is located on the drying barrel pallet 3. The hopper 5 is disposed on one side of the quantitative feeding mechanism 4 and is connected to the quantitative feeding mechanism 4. The compaction mechanism 6 is disposed below the conveying mechanism 1 and passes through the conveying mechanism 1. The controller 7 is disposed on the conveying mechanism 1, and the conveying mechanism 1, the quantitative feeding mechanism 4, the hopper 5, and the controller 7 are all electrically connected to the controller 7. In this embodiment, the controller 7 adopts a PLC control cabinet, and the PLC control cabinet controls the operation of the conveying mechanism 1, the quantitative feeding mechanism 4, and the compaction mechanism 6 through a built-in automatic program. Through the coordinated operation of the feeding mechanism, the quantitative feeding mechanism 4, the hopper 5, the vibration mechanism, and the controller 7, the automated filling and compaction of the desiccant is achieved, which effectively improves production efficiency, reduces manual operation, lowers production costs, and ensures the accuracy and consistency of desiccant filling.

[0062] Reference Figure 1In this embodiment, the conveying mechanism 1 includes a conveying frame 11 and a limiting component 2. A double-speed chain 12 and a driving component for driving the double-speed chain 12 are mounted on the conveying frame 11. The drying drum tray 3 is placed above the double-speed chain 12. It is worth noting that the driving component for driving the double-speed chain 12 can be a motor drive component from the prior art. In other embodiments, a hydraulic drive component or a pneumatic drive component from the prior art can also be used to drive the double-speed chain 12, as long as it can drive the double-speed chain 12. No specific structure of the driving component is limited here. The limiting component 2 is mounted on the conveying frame 11 and electrically connected to the controller 7. In this embodiment, the limiting component 2 includes multiple limit switches 21, each of which is electrically connected to the controller 7. The limit switches 21 are mounted on the conveying frame 11, and to ensure the normal operation of the limit switches 21, the limit switches 21 are... During installation, the contact height of the limit switch 21 must be higher than the height of the double-speed chain 12 to ensure that the contact of the limit switch 21 can contact the drying drum pallet 3 on the double-speed chain 12. The limiting member 22 is bolted to the conveyor frame 11 and electrically connected to the controller 7. In this embodiment, the number of limiting members 22 corresponds to the number of limit switches 21. In other embodiments, to improve the position detection accuracy of the drying drum pallet 3, the number of limit switches 21 and limiting members 22 can be increased according to actual needs, so that the number of switches and the number of limiting members 22 can be equal or unequal. Here, there is no limitation on the number of limit switches 21 and the number of limiting members 22. In this embodiment, the limiting member 22 adopts the pneumatic limiter of the prior art. In other embodiments, the hydraulic limiter of the prior art can also be used, as long as it can cooperate with the limit switch 21 to limit the drying drum pallet 3. Through the cooperation of the double-speed chain 12 and the drive assembly, the drying drum pallet 3 can be driven to move quickly and stably, improving the conveying efficiency. Meanwhile, the limiting component 2 ensures that the drying drum tray 3 stops at the designated position, facilitating subsequent desiccant filling and compaction operations. The combined use of the limit switch 21 and the limiting component 22 achieves precise control of the drying drum tray 3's position. The limit switch 21 detects the position of the drying drum tray 3 and transmits a signal to the controller 7. The controller 7 then controls the movement of the limiting component 22 based on the signal, ensuring that the drying drum tray 3 stops at the designated position and improving the accuracy of desiccant filling and compaction.

[0063] Reference Figure 2In one embodiment, the quantitative feeding mechanism 4 includes: a feeding frame 41, a pressure sensor 43, a weighing bin 44, and a feeding funnel 46. A dust cover 42 is bolted to the feeding frame 41. The dust cover 42 has an installation cavity, and its bottom wall has an opening that communicates with the installation cavity. The pressure sensor 43 is located in the installation cavity and is bolted to the feeding frame 41. The pressure sensor 43 is electrically connected to the controller 7. The weighing bin 44 is located in the installation cavity and is bolted to the pressure sensor 43. The weighing bin 44 has a weighing cavity, and its bottom wall has a weighing outlet that communicates with the weighing cavity. A movable plate 45 is provided at the weighing outlet of the weighing bin 44. 5. The weighing chamber 44 is hinged to the weighing outlet. A drive motor for driving the movable plate 45 to swing is bolted to the weighing chamber 44. The drive shaft of the drive motor is connected to the movable plate 45, allowing the movable plate 45 to swing when the drive motor operates, thereby controlling the opening and closing of the weighing outlet. It is worth noting that the drive motor driving the movable plate 45 to swing is a conventional technique in this field and is existing technology. Its specific structure and working principle will not be described in detail here. The feeding funnel 46 is located below the weighing chamber 44 and is bolted to the feeding frame 41. The opening position of the top wall of the feeding funnel corresponds to the position of the weighing outlet. The combined use of the pressure sensor 43 and the weighing chamber 44 enables precise control of the desiccant dosage. The dust cover 42 effectively prevents dust and other impurities from entering the weighing chamber 44, ensuring the purity of the desiccant. The feeding funnel 46 ensures that the desiccant can fall accurately and smoothly into the drying barrel.

[0064] Reference Figure 2 In one embodiment, to reduce dust generated when the desiccant enters the weighing chamber 44, a dust collection assembly 47 is provided on the dust cover 42. The dust collection assembly 47 is mounted on the dust cover 42 and communicates with the mounting cavity. The dust collection assembly 47 includes a vacuum cleaner, which is bolted to the dust cover 42, and its dust inlet is connected to the mounting cavity of the dust cover 42. The dust collection assembly 47 effectively removes dust and splashed desiccant from the dust cover 42, preventing spillage and improving the air quality around the equipment. This keeps the weighing chamber 44 clean and further ensures the purity and accuracy of the desiccant filling.

[0065] Reference Figure 3In one embodiment, the hopper 5 includes a hopper body 51 and a vacuum feeder 53. The top wall of the hopper body 51 has a feeding port, and a cover plate 52 is provided at the feeding port. The cover plate 52 is installed on the hopper body 51 by an interference fit.

[0066] Reference Figure 4 In one embodiment, the compaction mechanism 6 includes a base 61 and a vibration component. A lifting component 62 is mounted on the base 61. The vibration component 63 is positioned above and connected to the lifting component 62. Both the lifting component 62 and the vibration component 63 are electrically connected to the controller 7. The combined use of the lifting component 62 and the vibration component 63 enables the compaction of the desiccant within the drying drum. The lifting component 62 can adjust the height of the vibration component 63, allowing it to lift the drying drum support plate 3 from the double-speed chain 12, thus preventing damage to the double-speed chain 12 during compaction. The vibration component 63 generates vibration through the vibrator 633, ensuring even distribution and compaction of the desiccant within the drying drum, effectively improving the compaction effect.

[0067] Reference Figure 4In one embodiment, the lifting assembly 62 includes: a screw jack 621, a lifting platform 622, and limiting posts 623. The screw jack is bolted to the top wall of the base 61 and is electrically connected to the controller 7. The lifting platform 622 is located above the screw jack, and the lifting head of the screw jack is bolted to the bottom wall of the lifting platform 622. The bottom wall of the lifting platform 622 is provided with multiple limiting posts 623, and the base 61 is provided with limiting through holes 624 corresponding to the limiting posts 623. In this embodiment, there are four limiting posts 623, evenly distributed around the bottom wall of the lifting platform 622, and the limiting through holes 624 are provided. The number of 24 corresponds to the number of limiting posts 623. In other embodiments, the number of limiting posts 623 can be increased or decreased according to actual needs, as long as the lifting platform 622 is stable during lifting. The number of limiting posts 623 is not limited here. One end of the limiting post 623 is connected to the lifting platform 622 by bolts, and the other end passes through the limiting through hole 624. In this embodiment, to further improve the stability of the lifting platform 622 during lifting, a limiting sleeve is provided in the limiting through hole 624. The limiting sleeve is fitted onto the limiting post 623 and connected to the base 61 by bolts. Using a screw jack as the lifting component 62 fully utilizes the advantages of smooth lifting and high lifting accuracy of the screw jack. Secondly, the setting of the limiting posts 623 and the limiting through hole 624 ensures the stability of the lifting platform 622 during lifting, preventing swaying and deviation, and improving the accuracy of the vibration operation.

[0068] Reference Figure 4In one embodiment, the vibration assembly 63 includes a vibration platform 631 and a vibrator 633. The bottom wall of the vibration platform 631 is provided with a shock-absorbing support 632. The vibration platform 631 is connected to the lifting assembly 62 through the shock-absorbing support 632. The top wall of the shock-absorbing platform is bolted with two limiting blocks 634. The distance between the two limiting blocks 634 corresponds to the length or width of the drying drum tray 3. The vibrator 633 is bolted to the bottom wall of the vibration platform 631 and is electrically connected to the controller 7. In this embodiment, the shock-absorbing support 632 comprises a pressure spring, an upper fixed seat, and a lower fixed seat. The upper fixed seat is bolted to the bottom wall of the vibration platform, and the lower fixed seat is bolted to the top wall of the lifting platform 622. The pressure spring is located between the upper and lower fixed seats. Each of the opposing sides of the upper and lower fixed seats has a fitting groove. One end of the pressure spring is interference-fitted into the fitting groove of the upper fixed seat, and the other end is interference-fitted into the fitting groove of the lower fixed seat. To further improve the shock absorption effect, anti-vibration pads are placed between the pressure spring and the upper fixed seat, and between the pressure spring and the lower fixed seat. In other embodiments, existing hydraulic shock absorbers, pneumatic shock absorbers, and air springs, which can achieve shock absorption support, can also be used as the shock-absorbing support 632, as long as they can achieve the shock absorption support effect. By setting the shock-absorbing support 632 between the vibration platform 631 and the lifting assembly 62, the impact of vibration on the lifting assembly 62 and other components can be effectively reduced, improving the stability and durability of the device. The vibrator 633 ensures that the vibration platform 631 can generate sufficient vibration to ensure that the desiccant is evenly distributed and compacted within the drying drum. The limiting block 634 effectively restricts the movement of the drying drum support plate 3 during the compaction process, preventing the drying drum from tipping over due to the offset of the drying drum support plate 3, thus improving the safety and stability of the compaction operation.

[0069] Through the automated and coordinated operation of the conveying mechanism 1, the quantitative feeding mechanism 4, the hopper 5, the compaction mechanism 6, and the controller 7, the entire process of desiccant filling and compaction is automated, which significantly improves production efficiency, reduces labor costs and operational errors, and ensures accurate desiccant filling. At the same time, the compaction mechanism 6, through the precise coordination of lifting and vibration components 63, ensures that the desiccant is evenly distributed in the drying barrel, improving the drying effect. Furthermore, the design of the limiting component 2, the dust collection component 47, and the shock-absorbing support component 632 further enhances the stability, safety, and durability of the device operation.

[0070] The working principle of this application is as follows:

[0071] The operator places the drying drum on the drying drum tray 3 and starts the drive assembly, limit assembly 2, quantitative feeding mechanism 4, and vibration mechanism through the PLC program interface built into the control controller 7. Driven by the double-speed chain 12, the drying drum tray 3 moves to below the quantitative feeding mechanism 4. At this time, the drying drum tray 3 touches the limit switch 21 located below the quantitative feeding mechanism 4. After receiving the electrical signal from the limit switch 21, the PLC control cabinet controls the pneumatic limit switch located below the quantitative feeding mechanism 4 to activate, preventing the drying drum tray 3 from stopping below the quantitative feeding mechanism 4. Meanwhile, the vacuum feeder 53 delivers the desiccant from the chamber 51 to the weighing chamber 44. The pressure sensor 43 acquires the weight value of the weighing chamber 44. When the weight of the weighing chamber 44 reaches the preset value, the movable plate 45 opens, and the weighing chamber... The desiccant in 44 enters the drying barrel on the drying barrel tray 3 through the feeding funnel 46. At this time, the PLC controller 7 sends a control signal to lower the pneumatic limiter below the quantitative feeding mechanism 4. The drying barrel tray 3, which carries the drying barrel filled with desiccant, continues to move under the action of the double speed chain 12. At this time, the PLC controller 7 controls the pneumatic screw jack to drive the lifting platform 622 and the vibration component to rise together, so that the drying barrel tray 3 is placed on the vibration platform 631 and leaves the double speed chain 12. The screw jack stops operating. At this time, the vibrator 633 starts to vibrate the desiccant in the drying barrel on the vibration platform 631. After the vibration operation is completed, the screw jack operates to lower the lifting platform 622 and the vibration component, so that the drying barrel tray 3 returns to the double speed chain 12 and enters the next process with the operation of the double speed chain 12.
