Description

Technical Field

[0001] This invention relates to the field of sampling tube processing, and in particular to a tube feeding mechanism. Background Technology

[0002] With the development of livestock technology, livestock production methods are undergoing positive transformation, trending towards large-scale, intensive, ecological, specialized, automated, and intelligent production. This transformation is driving the overall livestock industry towards a more efficient and modern production model. Sampling tubes play a crucial role in livestock production. They are used to collect samples from livestock or the production environment for disease detection, health monitoring, nutritional analysis, and performance evaluation. However, current automated production of sampling tubes remains insufficient, particularly in the area of ​​tube feeding.

[0003] Sampling tubes typically have a long tubular structure with an open end and a hollow interior, with a cap inside one end to seal the tube.

[0004] Existing sampling tube feeding methods typically use a hopper as the feeding mechanism. The existing hopper consists of four vertical plates (front, back, left, and right) and a bottom plate, forming a top-opening hopper. The plates are usually angled, with the rear end higher than the front. A horizontally positioned strip-shaped discharge port begins at the bottom of the front plate. During feeding, multiple sampling tubes are placed into the hopper through the top opening, and then the sampling tubes roll along the bottom plate to the discharge port, allowing them to continuously exit, completing the feeding process.

[0005] However, this continuous feeding method is not suitable in certain situations. For example, during the packaging of sampling tubes, the tubes need to be sent to the packaging station one by one, with the second tube being sent after the first one is packaged. If a continuous feeding method is used, multiple sampling tubes will accumulate at the packaging station, making it impossible to package each tube individually.

[0006] The existing hopper can only handle continuous feeding. However, in some situations, it is necessary to feed the samples one by one. For example, when packaging sampling tubes, the feeding mechanism needs to deliver the sampling tubes one by one to the packaging station. After packaging one sampling tube, the next sampling tube is delivered. If feeding is continuous, there will be multiple sampling tubes at the packaging station, making it impossible to package each sampling tube individually.

[0007] Therefore, it is particularly necessary to design a new feeding mechanism to solve the problem that the existing feeding hopper cannot feed materials one by one. Summary of the Invention

[0008] The purpose of this invention is to provide a pipe feeding mechanism that addresses the aforementioned problems, enabling pipes to be fed one by one.

[0009] The technical solution adopted in this invention is as follows:

[0010] A pipe feeding mechanism includes a scraper, a baffle plate mounting component, a baffle plate, and a receiving tray;

[0011] The scraper and baffle mounting components are vertically arranged, and the gap between the scraper and baffle mounting components forms a material feeding channel; the lower end of the scraper is lower than the lower end of the baffle mounting component.

[0012] The baffle plate is arc-shaped, with its upper end rotatably mounted on the front of the baffle plate mounting component, and its lower end able to bypass the lower end of the baffle plate mounting component to block the material discharge channel outlet; the upper end of the baffle plate is connected to the baffle plate driving mechanism, which is used to drive the baffle plate to rotate.

[0013] The receiving tray is horizontally positioned below the material feeding channel; the receiving tray is connected to the receiving tray drive mechanism, which is used to drive the receiving tray to move back and forth.

[0014] When the baffle drive mechanism drives the baffle to rotate forward, opening the outlet of the discharge channel, the receiving plate drive mechanism drives the receiving plate to move forward and catch the pipe coming out of the discharge channel.

[0015] When the baffle drive mechanism drives the baffle to rotate backward, closing the discharge channel outlet, the receiving plate drive mechanism drives the receiving plate to move backward, causing the lower end of the scraper to scrape the pipe off from the front end of the receiving plate.

[0016] Furthermore, the front end of the receiving tray is bent upward to form a retaining edge; the height of the retaining edge is less than the diameter of the pipe.

[0017] Furthermore, the distance between the lower end of the scraper and the receiving tray is less than the diameter of the pipe.

[0018] Furthermore, the distance between the lower end of the baffle plate mounting component and the receiving tray is greater than the pipe diameter but less than twice the pipe diameter.

[0019] Furthermore, the scraper and baffle plate mounting components are fixedly mounted on the frame; a slide is provided below the receiving tray, and the receiving tray is mounted on the slide via a guide rail; a power shaft is rotatably mounted on the frame, and the baffle plate driving mechanism and the receiving tray driving mechanism are connected to the power shaft; the power shaft transmits power to the baffle plate driving mechanism, causing the baffle plate driving mechanism to rotate the baffle plate, and the power shaft transmits power to the receiving tray driving mechanism, causing the receiving tray driving mechanism to move the receiving tray back and forth on the slide.

[0020] Furthermore, a baffle plate pivot is provided on the front side of the baffle plate mounting component. The baffle plate pivot is horizontally positioned and rotatably mounted on the front side of the baffle plate mounting component. The upper end of the baffle plate is fixedly mounted on the baffle plate pivot.

[0021] The power shaft is horizontally arranged, rotatably mounted on the frame, and parallel to the baffle plate's rotating shaft;

[0022] The baffle plate driving mechanism includes a baffle plate cam, a rocker arm, a rocker arm guide wheel, and a rocker arm return spring. The baffle plate cam is mounted on the power shaft. One end of the rocker arm is connected to the baffle plate rotating shaft, and the rocker arm guide wheel is mounted on the other end of the rocker arm and contacts the baffle plate cam. The lower end of the rocker arm return spring is connected to the rocker arm, and the upper end of the rocker arm return spring is connected to the frame. The rocker arm return spring provides an upward pulling force, causing the rocker arm to drive the baffle plate to rotate backward.

[0023] Furthermore, the receiving tray drive mechanism includes a receiving tray cam, a pull rod, a pull rod guide wheel, and a pull rod return spring;

[0024] The receiving tray cam is mounted on the power shaft. The front end of the pull rod is connected to the rear end of the receiving tray. A pull rod guide wheel is provided at the rear end of the pull rod. The pull rod guide wheel contacts the receiving tray cam and is located behind the receiving tray cam.

[0025] The rear end of the pull rod return spring is connected to the rear end of the pull rod, and the front end of the pull rod return spring is connected to the frame; the pull rod return spring provides a horizontal forward pulling force, causing the pull rod to push the receiving tray forward.

[0026] Furthermore, the protrusions of the baffle plate cam and the receiving plate cam are 180° apart.

[0027] Furthermore, the baffle plate mounting component is a vertically arranged flat plate or a skeleton structure composed of several horizontal bars and vertical plates.

[0028] Furthermore, the frame includes a left upright plate and a right upright plate; the left and right upright plates are vertically arranged and parallel to each other; the scraper is fixedly arranged at the front end of the left and right upright plates; the baffle plate mounting component is located in front of the scraper, and the left and right ends of the baffle plate mounting component are respectively connected to the left and right upright plates via connecting rods; the left end of the power shaft is rotatably mounted on the left upright plate, and the right end of the power shaft is rotatably mounted on the right upright plate.

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] In this invention, the baffle plate blocks the outlet of the feeding channel to prevent the pipes from falling continuously, while the receiving tray and scraper work together to ensure that the pipes are fed one by one. When the receiving tray catches multiple pipes, the pipes are laid flat on the tray. Since the pipes are laid on the tray, when the tray moves backward, the lower end of the scraper will touch the pipes, pushing them forward to the front of the tray. This causes the pipes closest to the front of the tray to fall out first. If the tray continues to move backward, the pipes behind will also fall out from the front of the tray in sequence, thus completing the feeding of the pipes one by one.

[0031] When the inlet of the feeding channel in the pipe feeding mechanism of the present invention is connected with the outlet of the existing feeding hopper, the problem that the existing hopper cannot feed pipes one by one can be solved. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral 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 connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] like Figures 1-4 As shown, the present invention discloses a pipe feeding mechanism, which can be used for feeding pipes such as sampling pipes. The pipe feeding mechanism includes a scraper 1, a baffle plate mounting component 2, a baffle plate 3, and a receiving tray 4.

[0043] The scraper 1 and the baffle plate mounting part 2 are vertically arranged, and the gap between the scraper 1 and the baffle plate mounting part 2 forms a material feeding channel; the material feeding channel inlet is located at the upper end, the material feeding channel outlet is located at the lower end, and the lower end of the scraper 1 is lower than the lower end of the baffle plate mounting part 2.

[0044] The baffle plate 3 is arc-shaped. The upper end of the baffle plate 3 is rotatably mounted on the front of the baffle plate mounting part 2, and the lower end can bypass the lower end of the baffle plate mounting part 2 to block the outlet of the material discharge channel. The upper end of the baffle plate 3 is connected to the baffle plate 3 driving mechanism, which is used to drive the baffle plate 3 to rotate.

[0045] The receiving tray 4 is horizontally positioned below the material feeding channel; the receiving tray 4 is connected to the receiving tray 4 driving mechanism, which is used to drive the receiving tray 4 to move back and forth.

[0046] like Figure 1As shown, the feeding hopper 6 is located above the pipe feeding mechanism. When the pipe in the feeding hopper 6 enters the feeding channel from the upper end of the feeding channel, when the baffle plate 3 driving mechanism drives the baffle plate 3 to rotate forward, that is, rotate counterclockwise, so that the outlet of the feeding channel is opened, the receiving plate 4 driving mechanism drives the receiving plate 4 to move forward, so that it can catch the pipe coming out of the feeding channel; when the baffle plate 3 driving mechanism drives the baffle plate 3 to rotate backward, that is, rotate clockwise, so that the outlet of the feeding channel is closed, the receiving plate 4 driving mechanism drives the receiving plate 4 to move backward, so that the lower end of the scraper 1 scrapes the pipe off from the front end of the receiving plate 4.

[0047] In the above structure, the baffle plate 3 blocks the outlet of the discharge channel to prevent the pipes from falling continuously, while the receiving tray 4 and scraper 1 work together to ensure that the pipes are discharged one by one. When the receiving tray 4 catches multiple pipes, the pipes will be laid flat on the receiving tray 4. Since the pipes are laid on the receiving tray 4, when the receiving tray 4 moves backward, the lower end of the scraper 1 will touch the pipes, pushing the pipes forward to the front end of the receiving tray 4, so that the pipes closest to the front end of the receiving tray 4 fall out first. If the receiving tray 4 continues to move backward, the pipes behind it will also fall out from the front end of the receiving tray 4 in sequence, thus completing the discharge of the pipes one by one.

[0048] In actual use, the opening and closing time of the discharge channel outlet can be controlled according to the discharge speed of the pipe in the discharge channel to ensure that there is only one pipe on the receiving tray 4.

[0049] When the inlet of the feeding channel in the pipe feeding mechanism of the present invention is connected to the outlet of the existing feeding hopper 6, the problem that the existing hopper cannot feed pipes one by one can be solved.

[0050] In this invention, the lower end of the scraper 1 is lower than the lower end of the baffle plate mounting part 2 to ensure that the lower end of the scraper 1 can touch the pipe. The lower end of the baffle plate mounting part 2 is slightly higher to ensure that there is enough space at the lower end of the baffle plate mounting part 2 so that the lower end of the baffle plate 3 can pass through. This facilitates the lower end of the baffle plate 3 blocking the outlet of the feeding channel. At the same time, it also prevents the pipe from being scraped off the receiving tray 4 when the baffle plate 3 rotates forward.

[0051] To ensure that the scraper 1 can scrape off the pipe and facilitate the movement of the baffle 3, preventing the baffle 3 from scraping off the pipe; the distance between the lower end of the scraper 1 and the receiving plate 4 is less than the pipe diameter; the distance between the lower end of the baffle mounting part 2 and the receiving plate 4 is greater than the pipe diameter but less than twice the pipe diameter; and the distance between the lower end of the baffle 3 and the receiving plate 4 is greater than the pipe diameter.

[0052] Furthermore, the front end of the receiving tray 4 is bent upwards to form a retaining edge; the height of the retaining edge is less than the diameter of the pipe. The presence of the retaining edge prevents the pipe from rolling directly down.

[0053] Furthermore, the scraper 1 and the baffle plate mounting component 2 are fixedly mounted on the frame; a slide 5 is provided below the receiving tray 4, and the receiving tray 4 is mounted on the slide 5 via a guide rail; a power shaft 19 is rotatably mounted on the frame, and the drive mechanisms of the baffle plate 3 and the receiving tray 4 are connected to the power shaft 19; the power shaft 19 transmits power to the drive mechanism of the baffle plate 3, causing the drive mechanism of the baffle plate 3 to rotate, and the power shaft 19 also transmits power to the drive mechanism of the receiving tray 4, causing the drive mechanism of the receiving tray 4 to move the receiving tray 4 back and forth on the slide 5. The power shaft 19 is connected to a drive motor, which drives the power shaft 19 to rotate. The drive motor can be mounted on the frame.

[0054] If the baffle plate 3 drive mechanism and the receiving tray 4 drive mechanism operate independently, and one of them starts slowly, the baffle plate 3 and the receiving tray 4 cannot work together accurately, resulting in inaccurate material feeding. For example, if the receiving tray 4 drive mechanism starts slowly, the receiving tray 4 will not catch the pipe, and the pipe will fall directly. In this invention, both the baffle plate 3 drive mechanism and the receiving tray 4 drive mechanism are connected to the power shaft 19, enabling them to work in conjunction and start and stop simultaneously. This ensures that the baffle plate 3 and the receiving tray 4 can also work together more accurately.

[0055] Furthermore, such as Figure 3 As shown, a baffle plate rotating shaft 7 is provided on the front side of the baffle plate mounting component 2. The baffle plate rotating shaft 7 is horizontally arranged and rotatably mounted on the front side of the baffle plate mounting component 2; the upper end of the baffle plate 3 is fixedly mounted on the baffle plate rotating shaft 7.

[0056] The power shaft 19 is horizontally arranged, rotatably mounted on the frame, and parallel to the baffle plate shaft 7;

[0057] The drive mechanism of the baffle plate 3 includes a baffle plate cam 11, a rocker arm 9, a rocker arm guide wheel 10, and a rocker arm return spring 13. The baffle plate cam 11 is mounted on the power shaft 19. One end of the rocker arm 9 is connected to the baffle plate rotating shaft 7, and the rocker arm guide wheel 10 is mounted on the other end of the rocker arm 9 and contacts the baffle plate cam 11. The lower end of the rocker arm return spring 13 is connected to the rocker arm 9, and the upper end of the rocker arm return spring 13 is connected to the frame. The rocker arm return spring 13 provides an upward pulling force, causing the rocker arm 9 to drive the baffle plate 3 to rotate backward.

[0058] When the baffle cam 11 rotates clockwise, the protrusion of the baffle cam 11 contacts the rocker arm guide wheel 10, pressing the left end of the rocker arm 9 downward. At this time, the baffle 3 rotates forward, opening the outlet of the discharge channel. After the protrusion of the baffle cam 11 has rotated, the rocker arm return spring 13 provides an upward pulling force, pulling the left end of the rocker arm 9 upward. At this time, the baffle 3 rotates backward, closing the outlet of the discharge channel.

[0059] Furthermore, the receiving tray 4 drive mechanism includes a receiving tray cam 18, a pull rod 15, a pull rod guide wheel 16, and a pull rod return spring 17;

[0060] The receiving tray cam 18 is mounted on the power shaft 19. The front end of the pull rod 15 is connected to the rear end of the receiving tray 4. A pull rod guide wheel 16 is provided at the rear end of the pull rod 15. The pull rod guide wheel 16 contacts the receiving tray cam 18 and is located behind the receiving tray cam 18. The rear end of the pull rod return spring 17 is connected to the rear end of the pull rod 15, and the front end of the pull rod return spring 17 is connected to the frame. The pull rod return spring 17 provides a horizontal forward pulling force, causing the pull rod 15 to push the receiving tray 4 forward.

[0061] Since the guide wheel 16 is located behind the receiving tray cam 18, when the receiving tray cam 18 rotates clockwise, the protrusion of the receiving tray cam 18 contacts the guide wheel 16, pushing the pull rod 15 to move backward, causing the receiving tray 4 to move backward; after the protrusion of the receiving tray cam 18 has rotated, the pull rod return spring 17 provides a horizontal forward pulling force, driving the pull rod 15 to move forward, causing the receiving tray 4 to move forward.

[0062] In this invention, the protrusions of the baffle cam 11 and the receiving plate cam 18 are 180° apart. This ensures that when the material discharge channel outlet is open, the receiving plate 4 moves forward, and when the material discharge channel outlet is closed, the receiving plate 4 moves backward.

[0063] like Figure 3 As shown, the frame includes a left upright plate 12 and a right upright plate 14; the left upright plate 12 and the right upright plate 14 are vertically arranged and parallel to each other; the scraper 1 is fixedly arranged at the front end of the left upright plate 12 and the right upright plate 14; the baffle plate mounting component 2 is located in front of the scraper 1, and the left end and the right end of the baffle plate mounting component 2 are respectively connected to the left upright plate 12 and the right upright plate 14 through connecting rods 8; the baffle plate mounting component 2 is a vertically arranged flat plate or a skeleton structure composed of several horizontal bars and vertical plates. Figure 3 In the middle, the baffle plate mounting component 2 is a skeleton structure.

[0064] The left end of the power shaft 19 is rotatably mounted on the left vertical plate 12, and the right end of the power shaft 19 is rotatably mounted on the right vertical plate 14. The baffle cam 11 is located at the end of the power shaft 19, as shown below. Figure 3 As shown, the baffle cam 11 is located at the left end of the power shaft 19, outside the left vertical plate 12. The rocker arm 9 and the rocker arm return spring 13 are both located outside the left vertical plate 12, and the upper end of the rocker arm return spring 13 is connected to the outside of the left vertical plate 12. The receiving plate 4, the slide 5, and the receiving plate cam 18 are located between the left vertical plate 12 and the right vertical plate 14.

[0065] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
