Description

Technical Field

[0001] This invention relates to the field of blood collection tube production technology, specifically a blood collection management tube machine. Background Technology

[0002] Blood collection tubes are containers used in medical testing to collect and preserve blood samples. They are usually vacuum blood collection tubes and need to be used with venous blood collection needles. The tube body is usually made of transparent plastic or glass material, with a cavity in the middle for collecting blood samples. The production of plastic blood collection tubes involves steps such as injection molding, labeling, air washing, filling with medication, capping, and vacuuming.

[0003] Injection-molded blood collection tubes are typically transported to subsequent processes using belt conveyors. The conveyor belt is equipped with carriers for holding the blood collection tubes. To ensure accurate placement of the tubes onto the carriers, a material distribution mechanism with a hopper, chute, and distribution rollers is usually installed at one end of the conveyor. The hopper is generally funnel-shaped at the bottom, with the chute located at the bottom. After the blood collection tube is placed in the hopper, the distribution rollers push the tube from the bottom of the funnel into the chute, allowing it to fall accurately onto the carrier. However, once the blood collection tubes are transported to the front of the conveyor station, they need to be neatly arranged in the hopper. This is usually done by workers stacking the tubes in the hopper. Furthermore, as the number of tubes in the hopper decreases during subsequent processing, workers need to periodically replenish them. This replenishment and stacking of blood collection tubes incurs high labor costs, and prolonged operation can lead to decreased efficiency, requiring further improvement. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a blood collection management tube machine, including a feeding hopper and a feeding mechanism. The feeding mechanism includes a sliding frame slidably mounted on the feeding hopper, a feeding pipe slidably mounted on the left side of the sliding frame, a vertical moving component for driving the sliding frame to move up and down, a horizontal moving component for driving the feeding pipe to move left and right, an alignment plate slidably mounted on the front side of the feeding hopper, a forward and backward moving component for driving the alignment plate to move back and forth, a vibrating plate on the left side of the feeding hopper, and a feeding component installed between the vibrating plate and the feeding pipe.

[0005] The feeding assembly includes a feeding pipe 1 fixedly installed on the right side of the vibratory feeder outlet and in an L-shape, a feeding pipe 2 in an inverted L-shape movably installed at the top of the vertical section of the feeding pipe 1, and the right end of the horizontal section of the feeding pipe 2 movably connected to the left end of the feeding pipe.

[0006] In one possible implementation, the left and right sides of the feeding hopper are provided with openings for the sliding frame to pass through. The front side frame of the sliding frame is slidably installed inside the openings. The left and right sides of the feeding hopper are each provided with a baffle plate for blocking the openings. The top of the baffle plate is fixedly connected to the bottom of the sliding frame.

[0007] In one possible implementation, the front side frame of the sliding frame has a groove, the right end of the feeding pipe slides through into the interior of the sliding frame, the front side of the right end of the feeding pipe is slidably connected to the groove, and the rear side frame of the sliding frame is slidably installed on the rear side of the feeding hopper.

[0008] In one possible implementation, the vertical movement assembly includes a guide rail fixedly mounted on the rear side of the hopper, a lead screw rotatably mounted inside the guide rail, a slider threadedly connected to the outside of the lead screw, the slider slidingly connected to the guide rail vertically, the slider being fixedly connected to the rear side frame of the slide frame, and a drive motor fixedly mounted at the bottom of the guide rail, the top of the output shaft of the drive motor being drivenly connected to the bottom of the lead screw.

[0009] In one possible implementation, the left-right moving assembly includes a turntable rotatably mounted behind the slider and located behind the guide rail. The guide rail has a through groove for the turntable's central axis to slide up and down. A cylinder is fixedly mounted on the rear edge of the turntable, and a connecting rod is rotatably mounted on the cylinder. A cylinder is fixedly mounted on the rear side of the left end of the feeding pipe, and the end of the connecting rod away from the cylinder is rotatably connected to the cylinder. A gear is coaxially fixedly mounted on the front side of the turntable, and a rack is fixedly mounted on the rear side of the guide rail, with the rack meshing with the gear.

[0010] In one possible implementation, the forward and backward moving assembly includes a cam rotatably mounted on the top of the hopper, the cam being coaxially and fixedly connected to a lead screw, a push rod located in front of the cam being fixedly mounted on the top of the alignment plate, a concave frame being fixedly mounted on the front side of the hopper, and left and right symmetrical guide posts being fixedly connected to the front side of the alignment plate, the guide posts being slidably connected to the concave frame, and a return spring sleeved outside the corresponding guide post being fixedly connected between the alignment plate and the concave frame.

[0011] In one possible implementation, a guide sleeve is fixedly installed on the front side of the second feeding pipe, and a guide post two is fixedly installed on the front side of the first feeding pipe. The guide post two is slidably connected to the guide sleeve. A tube-pulling wheel is rotatably installed on the top of the horizontal section of the first feeding pipe. The tube-pulling wheel has several grooves evenly distributed around the circumference for pushing the blood collection tube to the right. A drive motor two is installed on the front side of the first feeding pipe, and the rear side of the output shaft of the drive motor two is connected to the tube-pulling wheel for transmission.

[0012] In one possible implementation, a limiting component for restricting the blood collection tube from being discharged to the right is installed at the top of the right end of the feeding pipe. A through hole is opened at the top of the feeding pipe, and a baffle is rotatably installed inside the through hole. A fixing block located on the right side of the through hole is fixedly installed at the top of the feeding pipe, and a return spring is fixedly connected between the top of the baffle and the left side of the fixing block.

[0013] The beneficial effects of this invention are as follows: 1. This invention uses a vibrating plate to orderly transport blood collection tubes into the first feeding pipe. Then, the blood collection tubes are transported through the first and second feeding pipes to the replenishing pipe. Finally, they are transported from the right end of the replenishing pipe to the feeding hopper. At the same time, the up-and-down moving component drives the sliding frame to move slowly upward, causing the sliding frame to move the replenishing pipe upward. The left-and-right moving component drives the replenishing pipe to move back and forth left and right as the sliding frame moves upward, so that the replenishing pipe evenly lays the blood collection tubes from right to left inside the feeding hopper. As the sliding frame gradually moves upward, the replenishing pipe can lay the blood collection tubes layer by layer. At the same time, no manual replenishment is required, reducing labor costs and improving production efficiency.

[0014] 2. In this invention, when the feeding pipe moves back and forth from left to right during its upward movement, the feeding pipe drives the second feeding pipe to move upward relative to the first feeding pipe. At the same time, the feeding pipe moves back and forth from left to right relative to the second feeding pipe. By adjusting the left and right lengths and vertical heights of the first and second feeding pipes, it is convenient to deliver blood collection tubes to the feeding pipes at different positions, which is highly flexible. At the same time, the baffle two restricts the blood collection tubes. As the total length of the horizontal section of the feeding pipe and the second feeding pipe gradually increases, the gap between the blood collection tubes located inside the horizontal section of the feeding pipe and the second feeding pipe will increase, causing the blood collection tubes to be no longer tightly arranged. At this time, the blood collection tubes on the right end cannot push away the baffle two, preventing the blood collection tubes from rolling off the right end of the feeding pipe and avoiding the blood collection tubes from obstructing the rightward movement of the feeding pipe.

[0025] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Please see Figure 1 - Figure 9 A blood collection management tube machine includes a feeding hopper 1 and a feeding mechanism 2. The feeding mechanism 2 includes a sliding frame 21 that is slidably mounted on the feeding hopper 1. A feeding pipe 22 is slidably mounted on the left side of the sliding frame 21. A vertical moving component 23 for driving the sliding frame 21 to move vertically is mounted on the rear side of the feeding hopper 1. A horizontal moving component 24 for driving the feeding pipe 22 to move horizontally is mounted on the sliding frame 21. An alignment plate 25 is slidably mounted on the front side of the feeding hopper 1. A front-back moving component 26 for driving the alignment plate 25 to move back and forth is mounted on the feeding hopper 1. A vibrating plate 27 is provided on the left side of the feeding hopper 1. A feeding component 28 is installed between the vibrating plate 27 and the feeding pipe 22.

[0027] The feeding assembly 28 includes a feeding pipe 281 that is fixedly installed on the right side of the discharge port of the vibrating plate 27 and is L-shaped. A feeding pipe 282 that is inverted L-shaped is movably installed at the top of the vertical section of the feeding pipe 281. The right end of the horizontal section of the feeding pipe 282 is movably connected to the left end of the feeding pipe 22.

[0028] In practical use, before starting the machine, the worker needs to fill the funnel-shaped cavity at the bottom of the feeding hopper 1 with blood collection tubes. At this time, the sliding frame 21 is located above the funnel-shaped cavity. After starting the machine, the injection-molded blood collection tubes are transported to the vibrating plate 27. The vibrating plate 27 is used to arrange and transport the blood collection tubes in an orderly manner. Then, the blood collection tubes are transported to the replenishment pipe 22 through the feeding pipe 1 281 and the feeding pipe 282. Finally, they are transported from the right end of the replenishment pipe 22 to the feeding hopper 1, continuously replenishing the inside of the feeding hopper 1 with blood collection tubes. No manual replenishment is required, which reduces labor costs and helps to improve production efficiency.

[0029] When the blood collection tubes are transported through the feeding pipe 22, the up-down moving component 23 drives the sliding frame 21 to move slowly upward, which in turn drives the feeding pipe 22 to move upward. The left-right moving component 24 drives the feeding pipe 22 to move back and forth left and right at the same time as the sliding frame 21 moves upward, so that the feeding pipe 22 evenly lays the blood collection tubes from right to left inside the feeding hopper 1. As the sliding frame 21 gradually moves upward, the feeding pipe 22 can lay the blood collection tubes layer by layer, avoiding the first-laid blood collection tubes from blocking the later-laid blood collection tubes. The front-back moving component 26 pushes the alignment plate 25 to move back and forth, which can make the alignment plate 25 level the front end of the blood collection tubes, so that the blood collection tubes are evenly laid in the feeding hopper 1, improving the smoothness of the laying.

[0030] When the feeding pipe 22 moves back and forth from left to right during the upward movement, the feeding pipe 22 drives the second feeding pipe 282 to move upward relative to the first feeding pipe 281. At the same time, the feeding pipe 22 moves back and forth from left to right relative to the second feeding pipe 282. By adjusting the left and right length and the up and down height of the first feeding pipe 281 and the second feeding pipe 282, it is convenient to deliver blood collection tubes to the feeding pipe 22 at different positions, which is highly flexible.

[0031] When the feeding pipe 22 moves to the top of the feeding hopper 1, it stops feeding blood collection tubes into the feeding hopper 1. After a period of time, the number of blood collection tubes inside the feeding hopper 1 will gradually decrease as it feeds materials to the subsequent processes. When the blood collection tubes descend to near the funnel-shaped cavity at the bottom of the feeding hopper 1, the up-down moving component 23 drives the sliding frame 21 to move downward, so that the sliding frame 21 returns to its initial height. Then the above steps are repeated to continuously feed materials.

[0032] Please see Figure 2 , Figure 3 and Figure 5 The left and right sides of the feeding hopper 1 are provided with openings 11 for the sliding frame 21 to pass through. The front side frame of the sliding frame 21 is slidably installed inside the opening 11. The left and right sides of the feeding hopper 1 are slidably installed with baffles 12 for blocking the openings 11. The top of the baffles 12 is fixedly connected to the bottom of the sliding frame 21.

[0033] In practical use, the openings 11 on the left and right sides of the feeding hopper 1 facilitate the up and down movement of the sliding frame 21. When the sliding frame 21 moves upward, the sliding frame 21 drives the baffle 12 to move upward together. The baffle 12 blocks the part of the opening 11 located below the sliding frame 21, preventing the laid blood collection tubes from falling from the opening 11 to the outside of the feeding hopper 1.

[0034] Please see Figure 2 , Figure 4 and Figure 5 The front side frame of the slide frame 21 has a slide groove 211. The right end of the feeding pipe 22 slides through into the interior of the slide frame 21. The front side of the right end of the feeding pipe 22 is slidably connected to the slide groove 211. The rear side frame of the slide frame 21 is slidably installed on the rear side of the feeding hopper 1.

[0035] In practical use, the material supply pipe 22 is slidably supported by the groove 211, which improves the stability of the material supply pipe 22 when it moves. By setting the rear side frame of the sliding frame 21 on the rear side of the feeding hopper 1, it is convenient for the up and down moving component 23 to drive the sliding frame 21 to move up and down.

[0036] Please see Figure 4 and Figure 5 The vertical moving assembly 23 includes a guide rail 231 fixedly installed on the rear side of the feeding hopper 1. A lead screw 232 is rotatably installed inside the guide rail 231. A slider 233 is threadedly connected to the outside of the lead screw 232. The slider 233 is slidably connected to the guide rail 231. The slider 233 is fixedly connected to the rear side frame of the slide frame 21. A drive motor 234 is fixedly installed at the bottom of the guide rail 231. The top of the output shaft of the drive motor 234 is connected to the bottom of the lead screw 232 through a coupling.

[0037] Please see Figure 4 , Figure 5 and Figure 6The left and right moving component 24 includes a turntable 241 rotatably mounted on the rear side of the slider 233 and located behind the guide rail 231. The guide rail 231 has a through groove for the central axis of the turntable 241 to slide up and down. A cylinder 242 is fixedly mounted on the rear edge of the turntable 241. A connecting rod 243 is rotatably mounted on the cylinder 242. A cylinder 244 is fixedly mounted on the rear side of the left end of the feeding pipe 22. The end of the connecting rod 243 away from the cylinder 242 is rotatably connected to the cylinder 244. A gear 245 is coaxially fixedly mounted on the front side of the turntable 241. A rack 246 is fixedly mounted on the rear side of the guide rail 231. The rack 246 meshes with the gear 245.

[0038] In practical use, the drive motor 234 drives the lead screw 232 to rotate, so that the lead screw 232 drives the slider 233 to move upward along the guide rail 231. The slider 233 drives the sliding frame 21 to move upward, and the sliding frame 21 drives the feeding pipe 22 to move upward, so that the feeding pipe 22 can replenish the blood collection tubes layer by layer from bottom to top.

[0039] When slider 233 moves upward, slider 233 drives turntable 241 and gear 245 to move upward together. When gear 245 moves upward, rack 246 drives gear 245 to rotate, causing gear 245 to drive turntable 241 to rotate. When turntable 241 rotates, it drives cylinder 242 and the right end of connecting rod 243 to move circumferentially along the edge of turntable 241. Connecting rod 243 pulls the feeding pipe 22 to move back and forth, so that the feeding pipe 22 can lay blood collection tubes from right to left.

[0040] Please see Figure 2 , Figure 4 and Figure 7 The forward and backward moving assembly 26 includes a cam 261 rotatably mounted on the top of the hopper 1. The cam 261 is coaxially and fixedly connected to the lead screw 232. A push rod 262 located in front of the cam 261 is fixedly mounted on the top of the alignment plate 25. A concave frame 263 is fixedly mounted on the front side of the hopper 1. A left-right symmetrical guide post 264 is fixedly connected to the front side of the alignment plate 25. The guide post 264 and the concave frame 263 are slidably connected back and forth. A return spring 265 sleeved on the outside of the corresponding guide post 264 is fixedly connected between the alignment plate 25 and the concave frame 263.

[0041] In practical use, when the lead screw 232 rotates, it drives the cam 261 to rotate together. When the protrusion of the cam 261 rotates to contact the push rod 262, the protrusion of the cam 261 can push the push rod 262 and the alignment plate 25 to move forward together. The guide post 264 plays a guiding and supporting role for the alignment plate 25, improving the stability of the alignment plate 25's movement. When the alignment plate 25 moves forward, it will compress the return spring 265. When the base circle of the cam 261 rotates to contact the push rod 262, the cam 261 can no longer push the push rod 262 forward. At this time, the rebound force of the return spring 265 is used to push the alignment plate 25 to move backward, so that the alignment plate 25 pushes and flattens the laid blood collection tube, which facilitates the accurate delivery of the blood collection tube in the future.

[0042] Please see Figure 1 and Figure 8 A guide sleeve 283 is fixedly installed on the front side of the second feeding pipe 282, and a guide post 284 is fixedly installed on the front side of the first feeding pipe 281. The guide post 284 and the guide sleeve 283 are slidably connected up and down. A tube-pulling wheel 285 is rotatably installed on the top of the horizontal section of the first feeding pipe 281. The tube-pulling wheel 285 has several grooves that are evenly distributed around the circumference and are used to push the blood collection tube to move to the right. A second drive motor 286 is installed on the front side of the first feeding pipe 281, and the rear side of the output shaft of the second drive motor 286 is connected to the tube-pulling wheel 285 for transmission.

[0043] In practical use, when the feeding pipe 22 drives the second feeding pipe 282 to move up and down, the second feeding pipe 282 will drive the guide sleeve 283 to slide up and down along the second guide post 284. The second guide post 284 guides the guide sleeve 283, improving the stability of the second feeding pipe 282 when it moves up and down. After the vibrating plate 27 delivers the blood collection tubes in an orderly manner to the first feeding pipe 281, the second drive motor 286 drives the tube-pulling wheel 285 to rotate, so that the tube-pulling wheel 285 can push the blood collection tubes along the first feeding pipe 281, the second feeding pipe 282 and the feeding pipe 22 in a timely manner, avoiding the blood collection tubes from accumulating in the vertical sections of the first feeding pipe 281 and the second feeding pipe 282 and remaining stationary, so that the vibrating plate 27 can continuously deliver the blood collection tubes to the first feeding pipe 281.

[0044] Please see Figure 3 , Figure 8 and Figure 9 A limiting component 29 for restricting the blood collection tube from being discharged to the right is installed at the top of the right end of the feeding pipe 22. A through hole 221 is opened at the top of the feeding pipe 22. A baffle 291 is rotatably installed inside the through hole 221. A fixing block 292 located on the right side of the through hole 221 is fixedly installed at the top of the feeding pipe 22. A reset spring 293 is fixedly connected between the top of the baffle 291 and the left side of the fixing block 292.

[0045] In practical use, the return spring 293 applies a downward elastic force to the baffle 291, allowing the baffle 291 to rotate downwards. The baffle 291 blocks the right end of the feeding pipe 22, preventing the blood collection tubes from rolling down randomly from the right end of the feeding pipe 22. Only when the blood collection tubes are neatly arranged together can the blood collection tubes on the left push the blood collection tubes on the right, causing the blood collection tubes on the right to push the baffle 291 to rotate upwards, allowing the blood collection tubes to be discharged from the right end of the feeding pipe 22.

[0046] As the feeding pipe 22 moves from right to left, the distance between the vertical section of the feeding pipe 22 and the second feeding pipe 282 gradually shortens, and the total length of the horizontal section of the feeding pipe 22 and the second feeding pipe 282 decreases. At this time, the blood collection tubes located inside the horizontal section of the feeding pipe 22 and the second feeding pipe 282 can be closely arranged. At this time, the baffle 291 cannot block the blood collection tubes, allowing the blood collection tubes to be discharged smoothly from the right end of the feeding pipe 22. However, when the feeding pipe 22 moves to the right, as the total length of the horizontal section of the feeding pipe 22 and the second feeding pipe 282 gradually increases, the gap between the blood collection tubes located inside the horizontal section of the feeding pipe 22 and the second feeding pipe 282 will increase, causing the blood collection tubes to no longer be closely arranged. At this time, the blood collection tubes at the right end cannot push away the baffle 291, preventing the blood collection tubes from rolling down from the right end of the feeding pipe 22 and avoiding the blood collection tubes from obstructing the rightward movement of the feeding pipe 22.

[0047] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," "installed," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, an integral connection, or a sliding connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
