All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The following embodiments are used to illustrate this utility model but should not be used to limit its scope.

[0043] The following is combined Figure 1 This invention describes a high-precision explosion-proof servo conveying device, comprising a track module 2, a drive module 1, and a limiting module 3. The track module 2 is installed on the working platform of a hydraulic press for pressing medicine. The drive module 1 is slidably mounted on the track module 2. The limiting module 3 is disposed on the side of the track module 2. A dustproof module 5 is covered and connected to the drive module 1. A protective module 4 is disposed between the limiting module 3 and the track module 2.

[0044] This utility model rationally optimizes the spatial layout of the conveying device, effectively reduces the footprint of the explosion-proof room in the factory, effectively saves the construction funds of the new factory, and is also conducive to the upgrading and transformation of equipment in the old factory with limited space.

[0045] In a preferred embodiment of this utility model of a high-precision explosion-proof servo conveying device, such as... Figure 4As shown, the track module 2 includes a support rail 201, a movable rail 208, an external rail 204, a left bracket 202, a right bracket 203, and an external bracket assembly 205.

The adjusting pad 207 is made of wear-resistant and corrosion-resistant materials, which not only improves the durability of the connection but also effectively isolates the conveying device from the influence of the external environment, such as preventing the intrusion of moisture, dust, and other impurities, thereby extending the service life of the conveying device. The adjusting pad 207 is also easy to disassemble and replace; when maintenance or replacement of conveying device components is required, the adjusting pad 207 can be easily removed, improving work efficiency.

[0053] Furthermore, such as Figure 2 and Figure 3 As shown, the drive module 1 includes a vehicle body 107, an explosion-proof servo motor 101, a reducer 102, a mounting base 103, a synchronous pulley 104, a transition shaft 105, a main drive shaft 108, a synchronous belt 109, an adjustment assembly 110, and a driven shaft 111.

[0054] The upper part of the vehicle body 107 is provided with a mounting base 103 and an adjustment component 110. The explosion-proof servo motor 101 and the reducer 102 are mounted on the mounting base 103. The reducer 102 is connected to the explosion-proof servo motor 101. The synchronous pulley 104 is connected to the output shaft of the reducer 102 through the transition shaft 105. A pressure cover 106 is provided between the transition shaft 105 and the vehicle body 107.

[0055] The lower part of the car body 107 is equipped with four bearing seats 112.

[0056] Preferably, the adjusting assembly 110 is used to fine-tune the position of the synchronous pulley 104 to ensure the transmission accuracy between the synchronous belt 109 and the main drive shaft 108. The adjusting assembly 110 includes an adjusting bolt and an adjusting nut. The adjusting bolt passes through the mounting base 103 and abuts against the transition shaft 105. The adjusting nut is threadedly connected to the adjusting bolt. By rotating the adjusting nut, the transition shaft 105 can be pushed or pulled, thereby fine-tuning the position of the synchronous pulley 104. This not only improves the transmission accuracy of the conveying device but also ensures that the conveying device maintains stable performance during long-term use.

[0057] Preferably, the explosion-proof servo motor 101 adopts a high-performance servo control system, which has precise control capabilities and stable operating performance, and can meet the requirements of high-precision conveying. At the same time, the explosion-proof servo motor 101 also has good explosion-proof performance, which can operate safely in flammable and explosive environments, thereby improving the safety and reliability of the conveying device.

[0058] Preferably, the reducer 102 is used to reduce the output speed of the explosion-proof servo motor 101 and increase the output torque to meet the power requirements of the conveying device. The reducer 102 is connected to the explosion-proof servo motor 101 and transmits the power of the explosion-proof servo motor 101 to the synchronous pulley 104 through precise gear transmission.

[0059] Preferably, the transmission system consisting of the synchronous pulley 104 and the synchronous belt 109 has advantages such as high transmission accuracy, smooth operation, and low noise. The synchronous pulley 104 is connected to the output shaft of the reducer 102 via the transition shaft 105 to ensure accurate power transmission. The synchronous belt 109 connects the main drive shaft 108 and the synchronous pulley 104, transmitting power to the main drive shaft 108 to drive the conveyor device.

[0060] Preferably, the explosion-proof servo motor 101 is equipped with a servo controller, which uses a closed-loop control method to compare feedback signals from the encoder and position sensor to achieve simultaneous control, thereby adjusting the output signal to control the explosion-proof servo motor 101 to move into precise positioning.

[0062] The bracket adjustment assembly 301 is installed on the foundation embedded part. A drag chain guide groove 302 is formed on the upper part of the bracket adjustment assembly 301. The drag chain mounting bracket 305 is installed on the vehicle body 107. An auxiliary bracket 303 is installed on the working platform of the hydraulic press. A guide groove 304 is formed on the upper part of the auxiliary bracket 303. An explosion-proof drag chain 309 is installed on the drag chain guide groove 302 and the guide groove 304. An insertion limit bracket 306 is provided at the end of the support guide rail 201 near the bracket adjustment assembly 301. An exit limit bracket 307 and an exit limit stop 308 are provided at the end of the external guide rail 204 away from the support guide rail 201.

[0063] Preferably, the limit module 3 is equipped with an explosion-proof proximity switch as a secondary protection signal point for moving into position, and combined with the limit stop, effectively ensuring the safety of the conveying device and the safety of the powder and mold conveying process.

[0064] Preferably, the explosion-proof cable chain 309 slides within the cable chain guide groove 302 and guide groove 304, protecting the cables and pipelines from damage by the external environment while ensuring their smooth movement. The insertion limit bracket 306 limits the position of the vehicle body 107 during insertion, ensuring it stops accurately at the predetermined position. The removal limit bracket 307 and the removal limit stop 308 work together to limit the position of the vehicle body 107 during removal, preventing excessive movement. Through the setting of the limit module 3, precise control of the vehicle body 107's movement position is achieved, improving the stability and accuracy of the conveying device.

[0065] Furthermore, such as Figure 6 and Figure 7 As shown, the protection module 4 includes a support frame 401 mounted on the connecting bracket 206 and a guide rail protection plate 403 mounted on the external guide rail 204 and the supporting guide rail 201. The support frame 401 is equipped with an anti-static buffer pad 402. The anti-static buffer pad 402 effectively prevents sparks generated by static electricity from damaging the explosion-proof servo conveying device, improving overall safety. The guide rail protection plate 403 protects the guide rail, reducing interference from external factors and extending its service life. Simultaneously, the guide rail protection plate 403 prevents dust and debris from entering the guide rail, ensuring smooth operation. The protection module 4 further enhances the reliability and stability of the explosion-proof servo conveying device.

[0066] Furthermore, such as Figure 8 As shown, the dustproof module 5 includes a vehicle body cover 501, a main drive shaft cover 503, a bridge protection plate 505, a drag chain annular seal 507, and a micro positive pressure mechanism 508.

The micro positive pressure mechanism 508 is connected to the limit module 3 and can be conveyed into the drive module 1.

[0068] Preferably, the installation of the body cover 501 and the main drive shaft cover 503 effectively prevents dust, debris, and other impurities from entering the interior of the body 107, protecting the precision components inside the body 107 from contamination, thereby ensuring the high-precision operation of the conveying device. The installation of the bridge guard plate 505 and the drag chain annular seal 507 further enhances the dustproof effect, ensuring the smooth operation of moving parts such as the drag chain and bridge, and reducing the failure rate caused by impurities. The introduction of the micro-positive pressure mechanism 508, by establishing a micro-positive pressure environment between the limit module 3 and the drive module 1, effectively prevents harmful substances such as dust and moisture in the outside air from entering the interior of the drive module 1, further improving the reliability and service life of the drive module 1. The comprehensive application of the dustproof module 5 significantly improves the overall protection performance of the explosion-proof servo conveying device, ensuring its stable operation in harsh environments.
