Description

Technical Field

[0001] This invention relates to the field of milk sample transport technology, and in particular to a track-type transport device for milk sample testing. Background Technology

[0002] In the field of dairy product quality testing, automated milk sample transport is a key link to achieve batch testing and improve testing efficiency. Existing milk sample transport equipment mostly adopts the form of multiple conveyor belts in conjunction with transfer mechanisms to realize the flow of samples between different transport stations.

[0003] Existing track-type conveyor equipment for milk sample testing, while enabling rapid transfer of milk samples via grippers, keeps the bottles in continuous motion during sample transport. Direct gripping of the bottles by the grippers results in contact and impact due to speed differences, easily damaging the bottle's outer wall and causing it to tip over, spilling the milk sample. This affects the bottle's appearance, contaminates the conveyor belt and working environment, and interferes with subsequent testing procedures. Therefore, there is an urgent need for a track-type conveyor equipment for milk sample testing. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a track-type conveying device for milk sample testing.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A track-type conveying device for milk sample testing includes a sample input device and a sample output device. The sample input device is used to convey milk samples, and the sample output device is used to convey milk samples to be tested. The conveying directions of the sample input device and the sample output device are opposite. A transfer mechanism for transferring milk samples to be tested is provided between the sample input device and the sample output device. The transfer mechanism can transport milk samples from the sample input device conveyor belt to the sample output device conveyor belt. During the process of clamping and transferring the milk samples, the speed of the transfer mechanism is consistent with the speed at which the milk samples are transported by the sample input device conveyor belt and the sample output device conveyor belt. The external part of the transfer mechanism is also provided with two sample clamping mechanisms for clamping the milk sample bottles, and the clamping opening direction is consistent with the conveying direction of the sample input device conveyor belt and the sample output device conveyor belt, respectively.

[0006] As a preferred technical solution of the present invention, the transfer mechanism includes a fixed frame fixed between the sample input device and the sample output device. A servo motor is provided on the top of the fixed frame, and a transmission plate is provided on the output shaft of the servo motor. Two drive disks that drive the sample clamping mechanism to move up and down are provided on both sides of the transmission plate, and a transmission mechanism that drives the drive disks to rotate is provided between the transmission plate and the drive disks. The servo motor is inverted on top of the fixed frame, and the output shaft of the servo motor passes through the top of the fixed frame. The output shaft of the servo motor is fixed to the top of the transmission plate, and the transmission plate is set in the upper half of the fixed frame. The output shaft of the servo motor drives the transmission plate to rotate, and the transmission plate drives the drive disk to rotate through the transmission mechanism. The drive disk drives the sample clamping mechanism to rotate around the axis of the drive disk, and the clamping opening direction of the sample clamping mechanism always remains consistent.

[0007] As a preferred embodiment of the present invention, the transmission mechanism includes a gear rotatably mounted on a transmission plate, a drive ring is provided outside the gear, and two toothed rings are symmetrically arranged on the inner wall of the drive ring, the number of teeth of the toothed rings being equal to the number of teeth of the gear. The outer wall of the drive ring is also provided with a load-bearing rod, a fixing rod is fixed in the middle of the load-bearing rod, and the bottom of the fixing rod is fixed to the fixing frame. The gear rings inside the drive ring are respectively set on both sides near the sample input device and the sample output device. When the servo motor drives the transmission plate to rotate, the transmission plate drives the gear to rotate around the axis of the servo motor, so that the gear rotates inside the drive ring. When the gear contacts the gear ring of the drive ring, the gear rotates on its own, and the gear drives the drive disk to rotate.

[0008] As a preferred technical solution of the present invention, two worm gears are rotatably connected to the bottom of the transmission plate, a transmission rod is fixed on the side of the drive disk away from the sample clamping mechanism, and a worm wheel that meshes with the worm gear is fixed on the end of the transmission rod away from the drive disk. The outer wall of the transmission rod is also fitted with a positioning sleeve, and a support arm is fixed at the bottom of the positioning sleeve. A connecting rod is fixed at the end of the support arm away from the positioning sleeve, and the connecting rod is rotatably connected to the outer wall of the fixed rod. When the servo motor drives the transmission plate to rotate around the axis of the servo motor, the transmission plate drives the gear to rotate around the axis of the servo motor through the worm gear. The gear engages with the gear ring of the drive ring, and the gear drives the worm gear to rotate. The worm gear drives the worm wheel to rotate, and the worm wheel drives the drive disc to rotate around the axis of the drive rod through the transmission rod.

[0009] As a preferred embodiment of the present invention, a support frame is fixed to the top of the fixed rod, a reciprocating block is slidably connected inside the support frame, and a limit frame is fixed to the top of the reciprocating block. The bottom of the gear is rotatably connected to a slider, and a groove is provided in the middle of the limiting frame to facilitate the movement of the slider. When the transmission plate drives the gear to rotate around the axis of the servo motor, the gear rotates inside the drive ring, and the gear drives the slider to move. The slider cooperates with the slide groove and moves inside the slide groove. At the same time, the slider can also reciprocate inside the support frame through the drive limit frame.

[0010] As a preferred embodiment of the present invention, the outer wall of the drive ring is further fitted with an assembly block, and a locking block is fixed to the top of the load-bearing rod.

[0011] As a preferred technical solution of the present invention, a wear-resistant sleeve is fixed inside the drive disk, and a force-bearing rod is inserted inside the wear-resistant sleeve. The end of the force-bearing rod away from the transmission rod is connected to the sample clamping mechanism, and a number of counterweights are provided at the end of the force-bearing rod away from the sample clamping mechanism. The end of the force-bearing rod away from the sample clamping mechanism is screwed with a mounting plate, and a blocking frame is also provided above the counterweight. A locking rod is fixed on the side of the blocking frame near the drive plate. The wear-resistant sleeve also has several protrusions inside to increase the friction of the force-bearing rod. The force-bearing rod is U-shaped, and the size of the end of the force-bearing rod connected to the sample clamping mechanism is larger than the size of the end connected to the mounting plate. The top of the mounting plate has a threaded part, and the end of the force-bearing rod away from the sample clamping mechanism has a threaded hole that matches the threaded part. The counterweight is fitted onto the outside of the mounting plate. The drive plate has a slot that matches the locking rod on the side near the transmission rod. The lower half of the blocking frame also has a rectangular groove. The blocking frame is fitted onto the end of the force-bearing rod with the threaded hole. The bottom of the rectangular groove is provided with an insertion hole that matches the threaded part. First, the blocking frame is placed on the outside of the force-bearing rod. Pushing the blocking frame drives the locking rod to insert into the slot of the drive plate. Then, the counterweight is placed on the outside of the mounting plate. After pushing the mounting plate to drive the blocking frame, the mounting plate is rotated. The threaded part of the mounting plate matches the threaded hole of the force-bearing rod. The mounting plate and the counterweight are installed on the outside of the force-bearing rod. The pressure generated by the sample clamping mechanism and the counterweight increases the downward pressure of the force-bearing rod, preventing the force-bearing rod from rotating when the drive plate rotates, so that the force-bearing rod is always kept in an inverted position.

[0012] As a preferred technical solution of the present invention, the sample clamping mechanism includes a cylinder fixed to the end of the force rod away from the mounting plate, two positioning plates fixed to the outside of the cylinder, two clamping arms rotating at the ends of the two positioning plates away from the cylinder, and two main clamping wheels rotatably connected at the ends of the two clamping arms away from the two positioning plates. Two transmission arms are rotatably connected to the middle of the two clamping arms. A push block is rotatably connected to one side of the two transmission arms facing each other. The output shaft of the cylinder is fixed to the push block. An extension block is fixed to the end of the push block away from the cylinder. A secondary clamping wheel is rotatably connected to the end of the extension block away from the push block. The cylinder is internally equipped with a drive module assembly that drives the cylinder telescopic rod to extend and retract. The drive module assembly can be referenced from Chinese Patent Publication No. CN219384543U. When the cylinder telescopic rod extends outward, the cylinder drives the propulsion block to move. The propulsion block drives the extension block to move. The extension block drives the secondary clamping wheel to move towards the side closer to the main clamping wheel. At the same time, the propulsion block drives the transmission arm to move. The transmission arm drives the extension block to move around the end of the positioning plate away from the cylinder. The clamping arm drives the distance between the two main clamping wheels to decrease. The milk bottle is clamped by the two main clamping wheels and the secondary clamping wheel.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention utilizes the coordinated structure of a sample input device, a sample output device, a transfer mechanism, a sample clamping mechanism, a drive ring, a drive disk, a force-bearing rod, gears, a worm gear, and a worm. The drive disk drives the sample clamping mechanism to move, ensuring that its movement speed is consistent with the sample input and output device's sample conveying speed. This achieves a relatively stationary state between the sample clamping mechanism and the milk bottle during the clamping and transfer process, avoiding contact impacts caused by speed differences. It effectively prevents damage to the outer wall of the milk bottle, bottle tipping, and leakage of the internal milk sample. This not only ensures the integrity of the milk bottle's appearance but also avoids sample contamination of the conveyor belt and working environment, ensuring that the milk sample is stably, reliably, and without damage during the testing and transfer process. 2. This invention utilizes the cooperation of a servo motor, transmission plate, drive ring, worm gear, worm, transmission rod, and reciprocating block to drive the disk to achieve intermittent motion, which greatly improves the stability of milk sample transfer, avoids damage to the outer wall of the milk bottle, bottle tipping, and internal sample leakage, and at the same time prevents milk samples from contaminating the conveyor belt and the testing environment, ensuring that the milk sample testing and transportation process is continuous, stable, and orderly. 3. This invention utilizes the cooperation of structures such as servo motor, transmission plate, drive ring, gear, worm gear, reciprocating block, slider, support frame and limit frame to enable the slider to make rectangular motion inside the drive ring. The slider drives the drive disk to make rectangular motion. The rectangular cyclic motion realizes continuous and uninterrupted batch sample transfer, which is suitable for the automated detection needs of large batch milk samples, effectively improves the overall conveying efficiency and reduces equipment standby and motion redundancy. 4. The present invention forms a reliable circumferential limit on the drive ring through the cooperation of the drive ring, the load-bearing rod, the assembly block and the locking block, so as to avoid the drive ring from rotating and deviating when the gear meshes with the drive ring, and ensure that the gear and the drive ring always maintain stable meshing transmission. This ensures the accurate movement trajectory of the drive disk and the sample clamping mechanism, ensures the stable and reliable transportation of milk samples throughout the process, and improves the operating accuracy and service life of the testing and transportation equipment. 5. This invention utilizes the cooperation of a drive disc, a load-bearing rod, a force-bearing rod, a counterweight, a blocking frame, and a mounting plate. The counterweight itself applies a continuous downward pressure to the force-bearing rod, ensuring that the force-bearing rod maintains a stable downward orientation. This counteracts the centrifugal force generated during the rotation of the drive disc, preventing the milk sample from shaking or shifting due to centrifugal force. Consequently, it prevents the milk bottle from tilting, tipping over, or leaking milk sample due to shaking, further improving the stability and reliability of milk sample transport. 6. This invention utilizes the coordinated structure of a drive disc, load-bearing rod, force-bearing rod, counterweight, blocking frame, mounting disc, locking rod, and wear-resistant sleeve. The locking rod is precisely positioned using a slot on the drive disc, and the locking rod, via the blocking frame, reliably constrains the force-bearing rod, ensuring its stable and synchronous rotation with the drive disc. This results in a smooth and orderly conveying of milk samples. Furthermore, when milk sample testing is not required, optimized transmission accelerates the sample conveying speed, reduces sample dwell time, and improves overall conveying efficiency. Adapting to different operational conditions, this invention further enhances the equipment's practicality and adaptability, ensuring the flexible and efficient operation of the testing and conveying production line.

[0025] refer to Figure 9 and Figure 10 As shown, a wear-resistant sleeve 326 is also fixed inside the drive disk 307. A force-bearing rod 311 is inserted inside the wear-resistant sleeve 326. The end of the force-bearing rod 311 away from the transmission rod 315 is connected to the sample clamping mechanism 4. Several counterweights 318 are provided at the end of the force-bearing rod 311 away from the sample clamping mechanism 4. The end of the force rod 311 away from the sample clamping mechanism 4 is screwed with a mounting plate 324, and a blocking frame 322 is also provided above the counterweight 318. A locking rod 323 is fixed on the side of the blocking frame 322 near the drive plate 307.

The force-bearing rod 311 is U-shaped, and the size of the end of the force-bearing rod 311 connected to the sample clamping mechanism 4 is larger than the size of the end connected to the mounting plate 324. The top of the mounting plate 324 is provided with a threaded part, and the end of the force-bearing rod 311 away from the sample clamping mechanism 4 has a threaded hole that matches the threaded part. The counterweight 318 is sleeved on the outside of the mounting plate 324. The drive plate 307 has a slot on the side near the transmission rod 315 that matches the locking rod 323. The lower half of the blocking frame 322 also has a rectangular groove. The blocking frame 322 is sleeved on the end of the force-bearing rod 311 with the threaded hole, and the bottom of the rectangular groove is open. The device has an insertion hole that matches the threaded part. First, the blocking frame 322 is fitted onto the outside of the force-bearing rod 311. Pushing the blocking frame 322 causes the locking rod 323 to be inserted into the slot of the drive plate 307. Then, the counterweight 318 is fitted onto the outside of the mounting plate 324. After pushing the mounting plate 324 to drive the blocking frame 322, the mounting plate 324 is rotated. The threaded part of the mounting plate 324 matches the threaded hole of the force-bearing rod 311. The mounting plate 324 and the counterweight 318 are installed on the outside of the force-bearing rod 311. The pressure generated by the sample clamping mechanism 4 and the counterweight 318 increases the downward pressure of the force-bearing rod 311, preventing the force-bearing rod 311 from rotating when the drive plate 307 rotates, so that the force-bearing rod 311 is always kept upside down.

[0026] Align the rectangular groove of the blocking frame 322 with the side of the force-bearing rod 311 away from the cylinder 401, and fit the blocking frame 322 onto the outside of the force-bearing rod 311. At the same time, the blocking frame 322 drives the locking rod 323 to insert into the slot of the drive plate 307. Fit the counterweight 318 onto the outside of the mounting plate 324. Push the mounting plate 324 through the blocking frame 322, and then rotate the mounting plate 324. The mounting plate 324 engages with the threaded hole of the force-bearing rod 311, and the mounting plate 324 is installed on the outside of the force-bearing rod 311. Through the cooperation of the sample clamping mechanism 4 and the counterweight 318, the downward pressing force on the force-bearing rod 311 is increased, preventing the force-bearing rod 311 from rotating when the drive plate 307 rotates, and ensuring that the force-bearing rod 311 always remains in an inverted and stable state.

[0027] Working principle: The output shaft of the servo motor 302 drives the transmission plate 303 to rotate around the axis of the servo motor 302. The transmission plate 303 drives the worm gear 316 to rotate around the axis of the servo motor 302. The transmission plate 303 drives the gear 312 to rotate around the axis of the servo motor 302. When the gear 312 moves to the side of the drive ring 304 with the toothed ring, the gear 312 engages with the toothed ring of the drive ring 304. The gear 312 rotates around its axis. The gear 312 drives the worm gear 316 to rotate. The worm gear 316 drives the worm wheel 313 to rotate. The worm wheel 313 drives the transmission rod 315 to rotate. The transmission rod 315 drives the drive disk 307 to rotate around the axis of the transmission rod 315. The drive disk 307 drives the cylinder 401 to rotate around the axis of the transmission rod 315 through the force rod 311, so that the rotation speed of the drive disk 307 is equal to the conveying speed of the sample input device 1 and the sample output device 2. When gear 312 contacts the gear ring of drive ring 304 and cylinder 401 moves to the side closer to sample input device 1, the drive module group inside cylinder 401 drives the telescopic end of cylinder 401 to work. The telescopic end of cylinder 401 retracts inward. The telescopic movement of cylinder 401 drives push block 405 to move closer to cylinder 401. Push block 405 drives auxiliary clamping wheel 408 to move closer to cylinder 401 through extension block 406. At the same time, push block 405 drives the end of transmission arm 404 connected to push block 405 to move closer to cylinder 401. Transmission arm 404 drives clamping arm 403 to rotate around one side of positioning plate 402. Positioning plate 402 drives main clamping wheel 407 to move, making the distance between the two main clamping wheels 407 smaller. The milk bottle is clamped by the two main clamping wheels 407 and auxiliary clamping wheel 408. When gear 312 contacts the gear ring of drive ring 304 and cylinder 401 moves to the side closer to sample output device 2, the drive module group inside cylinder 401 drives the telescopic end of cylinder 401 to work. The telescopic end of cylinder 401 extends outward. The telescopic movement of cylinder 401 drives push block 405 to move away from cylinder 401. Push block 405 drives auxiliary clamping wheel 408 to move away from cylinder 401 through extension block 406. At the same time, push block 405 drives the end of transmission arm 404 connected to push block 405 to move away from cylinder 401. Transmission arm 404 drives clamping arm 403 to rotate around one side of positioning plate 402. Positioning plate 402 drives main clamping wheel 407 to move, making the distance between the two main clamping wheels 407 larger. The milk bottle is released through the two main clamping wheels 407 and auxiliary clamping wheel 408.
