[0001] The present application relates to the technical field of cleaning equipment, in particular to an alternating pre-brushing device for test tubes. BACKGROUND

[0002] In the medical field, the cleanliness of test tubes is crucial to the accuracy of experimental results. The traditional test tube cleaning method mainly adopts manual brushing and upside-down drying. Although this method can ensure a certain degree of cleanliness, it has the problem of low efficiency. In particular, in places such as hospitals where the use of test tubes is large, manual brushing not only consumes time and effort, but also cannot meet the demand for rapid turnover. In addition, manual operation also has certain safety hazards, such as the possibility of hand fatigue or injury caused by long-term repetitive motion of the operator. SUMMARY

[0003] The problem to be solved by the present application is that the test tube is difficult to meet the cleaning demand of large use amount when using the traditional manual brushing and upside-down drying cleaning method, resulting in low cleaning efficiency, slow turnover rate, and high labor intensity.

[0004] To solve the above technical problems, the present application provides an alternating pre-brushing device for test tubes, which comprises a rack, a conveying belt arranged symmetrically on the upper part of the rack along the length direction thereof, test tubes with tube holders conveyed on the upper part of the conveying belt, a brushing assembly capable of horizontal movement and vertical lifting operation and taking the test tubes on the upper part of the two conveying belts as the object, and performing alternating washing and drying operations, a blocking assembly arranged on one side of the conveying belt for blocking and limiting the number of test tubes, and clamping assemblies symmetrically arranged on both sides of the conveying belt for clamping and fixing the test tubes.

[0005] Since the alternating pre-brushing device of the present application is designed with a brushing assembly, a blocking assembly and a clamping assembly, the continuous automatic brushing and drying operation of the test tubes can be realized through the organic combination of the brushing assembly, the blocking assembly and the clamping assembly, and effective limiting and fixing can be realized during brushing and drying. The problem of the prior art that the test tube is difficult to meet the cleaning demand of large use amount when using the traditional manual brushing and upside-down drying cleaning method, resulting in low cleaning efficiency, slow turnover rate, and high labor intensity, is solved.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application. EMBODIMENT

[0020] The present application relates to an alternating type pre-brushing device for test tubes, such as Figures 1-12As shown, the pre-rinsing device comprises a rack 1, a conveying belt 2, a brushing assembly 3, a blocking assembly 5, and a clamping assembly 4. The rack 1 serves as vertical support and provides a stable structural basis for the entire device. The rack 1 is externally covered with a metal structure, which serves as a shield and protection against external debris entering the device, while also beautifying the appearance. The conveying belt 2 is symmetrically arranged on the upper part of the rack 1 along the length direction of the rack 1. The conveying belt 2 is provided with side stops to prevent test tubes from falling during transportation. The upper part of the conveying belt 2 uniformly transports test tubes with tube holders, which are used to fix the test tubes and ensure their stability during transportation. The brushing assembly 3 is arranged on the upper part of the rack 1 and can be horizontally moved and vertically lifted. The brushing assembly 3 targets the test tubes on the upper part of the two sets of conveying belts 2 and performs alternating washing and drying operations. That is, when one set of test tubes is being washed, the other set is in a waiting or moving state, thereby realizing a continuous and efficient cleaning process. The blocking assembly 5 is symmetrically arranged on one side of the conveying belt 2 and serves as a blocking and limiting mechanism for the number of test tubes, ensuring that the number of test tubes washed each time is consistent and avoiding too many or too few test tubes entering the washing area, which would affect the cleaning effect. The clamping assembly 4 is symmetrically arranged on both sides of the conveying belt 2 and is used to clamp and fix the test tubes. During the washing process, the clamping assembly 4 tightly clamps the test tubes to prevent them from moving or falling due to water flow or brushing force, ensuring the stability and accuracy of the washing process.

[0021] The test tubes are transported into the device by the conveying belt 2, and the blocking assembly 5 ensures that the number of test tubes entering the washing area each time is consistent. The brushing assembly 3 performs horizontal movement and vertical lifting operations according to the preset program and then washes and dries the test tubes entering the washing area. Since there are two sets of conveying belts 2, one set of test tubes on the upper part of one set of conveying belts 2 is in a washing state, and the other set of test tubes on the upper part of the other set of conveying belts 2 is in a drying state, realizing alternating washing and drying operations of the test tubes and shortening the waiting time of the equipment. During the washing process, the clamping assembly 4 tightly clamps the test tubes to maintain their stability. After washing is completed, the test tubes are transported out of the device by the conveying belt 2 and enter the next process or storage area.

[0022] The brushing assembly 3 comprises a horizontal moving part 7, a vertical moving part 6, a brushing part 8 and a drying part 9. The horizontal moving part 7 is arranged inside the frame 1 and serves as the basis for the horizontal movement of the brushing assembly 3. The horizontal moving part 7 is capable of reciprocating horizontally through a driving mechanism. The design of the horizontal moving part 7 ensures that the brushing assembly 3 can move flexibly in the horizontal space to adapt to the brushing needs of test tubes in different positions. The vertical moving part 6 is arranged on the upper part of the horizontal moving part 7 and is connected to the horizontal moving part 7 to move horizontally with the horizontal moving part 7. The vertical moving part 6 is capable of lifting and lowering vertically through another driving mechanism. The design of the vertical moving part 6 enables the brushing part 8 to brush the inside of the test tube while ensuring stability and accuracy during brushing. The brushing part 8 is arranged on the lower part of the vertical moving part 6 and is connected to the vertical moving part 6 to move vertically with the vertical moving part 6. The brushing part 8 is usually made of soft bristles or sponge to adapt to the shape of the inner wall of the test tube and ensure the cleaning effect during brushing. Under the drive of the horizontal moving part 7 and the vertical moving part 6, the brushing part 8 can accurately and deeply enter the inside of the test tube for brushing operation. The drying part 9 is arranged inside the frame 1 and is relatively independent of the brushing assembly 3 but can move horizontally. The drying part 9 is usually equipped with a high-pressure airflow nozzle to spray high-pressure airflow into the test tube to quickly dry the inside of the test tube. The movement mechanism of the drying part 9 is independently set to ensure that it can accurately aim at the test tube for drying operation when needed.

[0023] After the test tubes enter the brushing area through the conveying belt 2, the brushing assembly 3 starts to work. First, the horizontal moving part 7 drives the vertical moving part 6 and the brushing part 8 to move horizontally above the test tubes. Then, the vertical moving part 6 drives the brushing part 8 to vertically descend and deeply enter the inside of the test tube for brushing operation. After brushing is completed, the brushing part 8 is lifted by the vertical moving part 6, and the horizontal moving part 7 drives the entire brushing assembly 3 to move to the position of another test tube above the conveying belt 2 for brushing. At the same time, when a group of test tubes are being brushed, another group of test tubes are in a waiting or moving state. At this time, the drying part 9 can move horizontally above the brushed test tubes as needed to spray high-pressure airflow into the test tubes for drying operation. Through alternating brushing and drying operation, efficient cleaning and rapid drying of the test tubes are achieved.

[0024] The horizontal moving part 7 comprises a horizontal supporting plate 10, a linear module 11, a first slide rail 13 and a first slide block 12. The horizontal supporting plate 10 is horizontally arranged and fixed inside the frame 1 and serves as the main supporting platform for the horizontal movement of the brushing assembly 3. The horizontal supporting plate 10 is designed to be strong enough to support the weight of the vertical moving part 6, the brushing part 8 and other components and ensure the stability during the movement. The linear module 11 is arranged below one side of the horizontal supporting plate 10 and serves as the main power source for driving the horizontal supporting plate 10 to move horizontally. The linear module 11 is usually driven by a motor-driven screw or a belt drive, which has the advantages of high precision, stable operation and low noise. Through the driving of the linear module 11, the horizontal supporting plate 10 can accurately move in the horizontal direction to drive the brushing assembly 3 to reach the designated position. The first slide rail 13 is arranged below the other side of the horizontal supporting plate 10 and opposite to the linear module 11, which serves as an auxiliary support and guide for the horizontal supporting plate 10. The design of the first slide rail 13 ensures the linearity and stability of the horizontal supporting plate 10 during the movement, preventing it from deviating or shaking. The first slide block 12 is fixed to the lower part of the horizontal supporting plate 10 and moves together with the horizontal supporting plate 10. The existence of the first slide block 12 reduces the friction between the horizontal supporting plate 10 and the first slide rail 13, making the movement smoother and also bearing part of the supporting function.

[0025] When the test tube needs to be brushed, the linear module 11 receives a control signal and starts to drive the horizontal supporting plate 10 to move horizontally. Under the driving of the linear module 11, the horizontal supporting plate 10 moves smoothly along the direction of the first slide rail 13, while the first slide block 12 slides on the first slide rail 13 to provide additional support and guidance for the horizontal supporting plate 10. The vertical moving part 6, the brushing part 8 and other components move together with the horizontal supporting plate 10 to reach the designated position for brushing. After the brushing is completed, the linear module 11 drives the horizontal supporting plate 10 to move in the opposite direction to bring the brushing assembly 3 back to the initial position or the position of the next test tube. During the whole movement process, the first slide rail 13 and the first slide block 12 ensure the linearity and stability of the horizontal supporting plate 10, guaranteeing the accurate movement of the brushing assembly 3 and the brushing effect.

[0026] The longitudinal moving part 6 comprises a longitudinal supporting plate 19, a first motor 14, a screw rod 15, a second sliding rail 17, a second sliding block 18 and a frame plate 16. The longitudinal supporting plate 19 is vertically arranged on the upper portion of the horizontal supporting plate 10 and serves as the main bearing platform for the vertical lifting of the brushing assembly 3. The longitudinal supporting plate 19 is designed to be strong enough to support the weight of the frame plate 16, the brushing part 8 and other components and ensure stability during lifting. The frame plate 16 is arranged on one side of the longitudinal supporting plate 19 in parallel with it and is used to fix and support the brushing part 8 to ensure the stability and accuracy of the brushing part 8 during lifting and brushing. The first motor 14 is arranged on the upper portion of the longitudinal supporting plate 19 and is used to drive the vertical lifting of the frame plate 16. The first motor 14 is connected to the frame plate 16 through a transmission mechanism to convert the rotary motion of the motor into the vertical lifting motion of the frame plate 16. The screw rod 15, as a part of the transmission mechanism, is connected to the first motor 14 to transmit the rotary motion of the motor to the frame plate 16. The design of the screw rod 15 ensures the stability and accuracy of the transmission, enabling the frame plate 16 to accurately lift vertically. The second sliding rail 17 is arranged on the upper portion of the longitudinal supporting plate 19 in parallel with the lifting direction of the frame plate 16 and serves as an auxiliary support and guide for the frame plate 16 to ensure its linearity and stability during lifting. The second sliding block 18 is matched with the second sliding rail 17 and is fixed on the side of the frame plate 16 to lift together with the frame plate 16. The presence of the second sliding block 18 reduces the friction between the frame plate 16 and the second sliding rail 17, making the lifting smoother and also bearing part of the support.

[0027] When the test tube needs to be brushed, the first motor 14 receives a control signal and starts to drive the screw rod 15 to rotate. The rotation of the screw rod 15 is transmitted to the frame plate 16 through the transmission mechanism, causing the frame plate 16 to lift vertically on the longitudinal supporting plate 19. At the same time, the second sliding rail 17 and the second sliding block 18 provide auxiliary support and guidance for the frame plate 16 to ensure its linearity and stability during lifting. The brushing part 8 is fixed on the frame plate 16 and lifts together with it. When the frame plate 16 descends to the appropriate position, the brushing part 8 penetrates into the test tube for brushing. After brushing, the first motor 14 reverses the rotation of the screw rod 15, and the frame plate 16 rises under the action of the transmission mechanism, bringing the brushing part 8 back to the initial position.

[0028] The brush cleaning part 8 comprises a frame plate 21 and a second motor 20, the frame plate 21 is arranged on the bottom side of the frame plate 16 as a bearing and fixing platform of the brush 22, the design of the frame plate 21 ensures the stability and accuracy of the brush 22 during the brushing process, and facilitates the connection and disassembly with the frame plate 16, the brush 22 is uniformly and spaced arranged on the lower part of the frame plate 21, forming two rows, the brush 22 is made of soft bristles, which can adapt to the shape of the inner wall and the mouth of the test tube, and ensure the cleaning effect during the brushing process, the brush 22 is designed as a horizontal rotary type, which can rotate under the drive of the second motor 20, and fully brush the inside of the test tube and the mouth, the second motor 20 is arranged on the upper part of the frame plate 21, used to drive the rotation of the brush 22, the second motor 20 is connected with the brush 22 through belt transmission, and the rotary motion of the motor is transmitted to the brush 22, so that the horizontal rotation is realized, the design of the second motor 20 considers the power, speed and noise, etc. Factors to ensure the efficiency and stability during the brushing process, the belt transmission mode uses belt (such as synchronous belt or V belt) as transmission medium, connecting the output shaft of the second motor 20 and the rotating shaft of the brush 22, the belt transmission mode has the advantages of stable transmission, low noise and simple structure, which is suitable for driving the rotation of the brush 22, and the speed and rotation direction of the brush 22 can be accurately controlled by adjusting the tension of the belt and the ratio of the wheel diameter.

[0029] When the test tube needs to be brushed, the longitudinal moving part 6 drives the brush cleaning part 8 to move to the inside of the test tube, then the second motor 20 receives the control signal and starts to drive the belt transmission mechanism to rotate, the rotation of the belt is transmitted to the brush 22 through the transmission shaft, so that the horizontal rotation is realized, the brush 22 contacts with the inner wall and the mouth of the test tube during the rotation, and the stains and residues are removed through the friction of the bristles, at the same time, the brush cleaning part 8 can move in the vertical direction with the longitudinal moving part 6 to adapt to test tubes of different heights, and the transverse moving part 7 drives the whole brush cleaning assembly 3 to move in the horizontal direction to realize the continuous brushing of multiple test tubes.

[0030] The blow-drying piece 9 comprises a carrier plate 23, a first air cylinder 24, a vertical plate 25, an air nozzle 26, a third sliding rail 28, and a third sliding block 27. The carrier plate 23 is horizontally arranged and fixed inside the rack 1, serving as the main bearing and fixing platform of the blow-drying piece 9. The carrier plate 23 is designed to be strong enough to support the weight of the vertical plate 25, the air nozzle 26, and other components, and to ensure stability during movement. The vertical plate 25 is symmetrically arranged at both ends of the carrier plate 23, used to fix and support the air nozzle 26. The design of the vertical plate 25 allows the air nozzle 26 to be evenly and stably distributed above the test tube, ensuring the uniformity of the blow-drying effect. The air nozzle 26 is arranged in intervals below the vertical plate 25, and multiple air nozzles 26 collectively constitute a blow-drying system. The air nozzle 26 is connected to the gas source through a connecting air pipe. When gas passes through, it forms a high-speed airflow, quickly blowing the inside and outside of the test tube. The design of the air nozzle 26 takes into account the direction and speed of the airflow to ensure the efficiency of the blow-drying effect. The first air cylinder 24 is arranged on the upper part of the carrier plate 23, used to pull the vertical plate 25 back and forth. The first air cylinder 24 is connected to the vertical plate 25 through a piston rod. When the air cylinder works, the piston rod extends or retracts, driving the vertical plate 25 and the air nozzle 26 to move horizontally. The design of the first air cylinder 24 takes into account factors such as stroke, speed, and force to ensure the stable movement of the vertical plate 25 and the air nozzle 26. The third sliding rail 28 is arranged on the lower part of the carrier plate 23, parallel to the moving direction of the vertical plate 25. The third sliding rail 28 plays an auxiliary supporting and guiding role for the vertical plate 25, ensuring the linearity and stability of the vertical plate 25 during movement. The third sliding block 27 is fixed on the upper part of the vertical plate 25 and moves with the vertical plate 25. The existence of the third sliding block 27 reduces the friction between the vertical plate 25 and the third sliding rail 28, making the movement smoother, and also bears part of the supporting role.

[0031] When the test tube cleaning is completed, the blow-drying piece 9 starts to work. The first air cylinder 24 receives a control signal, drives the piston rod to extend or retract, and drives the vertical plate 25 and the air nozzle 26 to move horizontally. At the same time, the third sliding rail 28 and the third sliding block 27 provide auxiliary support and guidance for the vertical plate 25, ensuring the linearity and stability of the vertical plate 25 during movement. The air nozzle 26 is connected to the gas source through a connecting air pipe. When gas passes through, it forms a high-speed airflow. The movement of the vertical plate 25 allows the air nozzle 26 to evenly blow the inside and outside of the test tube. By adjusting the arrangement of the air nozzle 26, the speed and direction of the airflow, and the moving speed and stroke of the vertical plate 25, efficient and uniform blow-drying of the test tube can be achieved.

[0032] The clamping assembly 4 includes a clamping seat 30, a clamping block 29, a second cylinder 33, a fourth sliding rail 31, and a fourth sliding block 32. The clamping seat 30 is symmetrically arranged on the upper part of the rack 1 on both sides of the conveying belt 2, serving as the main bearing and fixing platform of the clamping assembly 4. The clamping seat 30 is designed to be strong enough to support the weight of the clamping block 29, the second cylinder 33, and other components, and to ensure stability during reciprocating motion. The clamping block 29 is evenly and spacedly arranged on the upper part of the clamping seat 30, used for directly clamping test tubes. The design of the clamping block 29 takes into account the specifications and materials of the test tubes, ensuring that it can firmly clamp the test tubes while avoiding damage to them. The inner surface of the clamping block 29 can be provided with anti-slip texture or elastic cushioning to increase the stability and reliability of clamping. The second cylinder 33 is arranged on the upper part of the rack 1, used to push the clamping seat 30 to reciprocate. The second cylinder 33 is connected to the clamping seat 30 through a piston rod. When the cylinder works, the piston rod extends or retracts, driving the clamping seat 30 and the clamping block 29 to move in the horizontal direction, realizing the clamping and releasing of the test tubes. The design of the second cylinder 33 takes into account factors such as stroke, speed, and force to ensure stable movement and accurate clamping of the clamping assembly 4. The fourth sliding rail 31 is arranged on the upper part of the rack 1, parallel to the reciprocating direction of the clamping seat 30. The fourth sliding rail 31 plays a supporting and guiding role for the clamping seat 30, ensuring its linearity and stability during reciprocating motion. The fourth sliding block 32 is fixed to the lower part of the clamping seat 30 and reciprocates with it, cooperating with the fourth sliding rail 31. The existence of the fourth sliding block 32 reduces the friction between the clamping seat 30 and the fourth sliding rail 31, making the reciprocating motion smoother, and also bearing part of the supporting role.

[0033] When clamping the test tube is needed, the second cylinder 33 receives a control signal, drives the piston rod to extend, and drives the clamping seat 30 and the clamping block 29 to move towards the test tube. After the clamping block 29 contacts the test tube, it firmly clamps it. At the same time, the fourth sliding rail 31 and the fourth sliding block 32 provide auxiliary support and guidance for the clamping seat 30, ensuring its linearity and stability during clamping. During the brushing and drying process, the clamping assembly 4 maintains stable clamping of the test tube, ensuring that the test tube will not fall off or shift. When brushing and drying are completed, the second cylinder 33 reversely drives the piston rod to retract, driving the clamping seat 30 and the clamping block 29 away from the test tube, realizing the release of the test tube.

[0034] The blocking assembly 5 includes a baffle plate 35, a blocking strip 34, a third cylinder 36, a fifth sliding rail 37, and a fifth sliding block 38. The baffle plate 35 is symmetrically arranged on the upper part of the rack 1 on one side of the conveying belt 2 and serves as the main bearing and fixing structure of the blocking assembly 5. The baffle plate 35 is designed to be strong enough to support the weight of the blocking strip 34, the third cylinder 36 and other components and to ensure stability during the reciprocating extension and retraction. The blocking strip 34 is transversely arranged at the end of the baffle plate 35 and serves to shield the test tubes on the upper part of the conveying belt 2. The design of the blocking strip 34 takes into account the specifications of the test tubes and the width of the conveying belt 2 to ensure that it can effectively block the test tubes while avoiding damage to the test tubes. The material and surface treatment of the blocking strip 34 should ensure that it does not scratch or wear the test tubes when in contact with them. The third cylinder 36 is arranged on the upper part of the rack 1 and is used to drive the baffle plate 35 to reciprocate. The third cylinder 36 is connected to the baffle plate 35 through a piston rod. When the cylinder is working, the piston rod extends or retracts, driving the baffle plate 35 and the blocking strip 34 to move horizontally, thereby blocking and releasing the test tubes. The design of the third cylinder 36 takes into account factors such as stroke, speed and force to ensure stable movement and accurate blocking of the blocking assembly 5. The fifth sliding rail 37 is arranged on the upper part of the rack 1 parallel to the reciprocating direction of the baffle plate 35. The fifth sliding rail 37 serves as an auxiliary support and guide for the baffle plate 35 to ensure its straightness and stability during reciprocation. The fifth sliding block 38 is fixed to the lower part of the baffle plate 35 and reciprocates with the baffle plate 35. The presence of the fifth sliding block 38 reduces friction between the baffle plate 35 and the fifth sliding rail 37, making the reciprocation smoother, and also bears part of the supporting load.

[0035] When the test tubes need to be brushed and dried, the third cylinder 36 receives a control signal and drives the piston rod to extend, driving the baffle plate 35 and the blocking strip 34 to move towards the conveying belt 2 until the blocking strip 34 contacts and blocks the test tubes. At the same time, the fifth sliding rail 37 and the fifth sliding block 38 provide auxiliary support and guidance for the baffle plate 35 to ensure its straightness and stability during the blocking process. After the test tubes have been brushed and dried, the third cylinder 36 drives the piston rod to retract in the opposite direction, driving the baffle plate 35 and the blocking strip 34 away from the conveying belt 2, thereby releasing the test tubes and allowing them to continue moving forward.

[0036] The pre-rinsing device also comprises a washing liquid box 40 and a cleaning plate 39. The washing liquid box 40 is arranged in the middle of the upper part of the frame 1, corresponding to the position of the brush 22, to facilitate the cleaning operation of the brush 22. The design of the washing liquid box 40 takes into account the capacity of the cleaning liquid and the cleaning method of the brush 22, to ensure that it can effectively clean the brush 22. The opening of the washing liquid box 40 is reasonably designed, which is convenient for the brush 22 to enter and exit, and can prevent the cleaning liquid from splashing out. The cleaning plate 39 is arranged inside the washing liquid box 40 and is in contact with the cleaning area of the brush 22. The cleaning plate 39 is designed with a material having excellent cleaning performance, such as a fiber plate with a groove structure, which can penetrate into the gap between the bristles of the brush 22 and effectively remove dirt and residues attached to the bristles. The shape and size of the cleaning plate 39 match the shape and size of the brush 22, to ensure sufficient contact between the brush 22 and the cleaning plate 39 during the cleaning process, and to improve the cleaning effect.

[0037] During the tube brushing process, when the brush 22 is used for a period of time, some dirt and residues will be attached to the bristles, affecting the brushing effect. At this time, the control system of the device will issue an instruction to move the brush 22 to the position of the washing liquid box 40. After the brush 22 enters the washing liquid box 40, it is in contact with the cleaning plate 39. The cleaning liquid in the washing liquid box 40 penetrates into the gap between the bristles of the brush 22 through the micropores or fiber structure of the cleaning plate 39, thoroughly cleaning the bristles. At the same time, the cleaning performance material of the cleaning plate 39 can effectively remove the dirt and residues on the bristles, restoring the cleaning ability of the brush 22. After cleaning, the brush 22 exits the washing liquid box 40 and continues to perform the tube brushing work. By regularly or according to the brushing effect, the cleaning ability of the brush 22 can be ensured to always remain in the best state, improving the brushing quality and efficiency of the test tube.

[0038] In use, the test tubes are continuously or intermittently conveyed to the brushing area by the conveying belt 2. When the test tubes reach the brushing area, the baffle 35 and the blocking bar 34 of the blocking assembly 5 move to block the test tubes. The clamping seat 30 and the clamping block 29 of the clamping assembly 4 move to firmly clamp the test tubes on the tube holder. The transverse moving part 7 and the longitudinal moving part 6 of the brushing assembly 3 cooperate to adjust the position of the brushing part 8, so that the brush 22 is in contact with the outer wall of the test tube. The motor drives the brush 22 to rotate to brush the outer wall of the test tube. After brushing, the blowing part 9 moves above or to the side of the test tube. The fan provides airflow through the blowing port to blow dry the test tube. After blowing dry, the clamping seat 30 and the clamping block 29 of the clamping assembly 4 move to release the test tube. The baffle 35 and the blocking bar 34 of the blocking assembly 5 also move to allow the test tube to continue to move forward. The conveying belt 2 continues to convey the next test tube to the brushing area, and the above operation process is repeated. The test tubes can be pre-added with cleaning liquid during brushing. The test tubes that have been cleaned need to be subjected to subsequent centralized disinfection operation.
