Description

Technical Field

[0001] The invention relates to the field of sampling tube processing, in particular to a tube material blanking mechanism. Background Art

[0002] With the development of animal husbandry technology, animal husbandry production methods have undergone positive changes, and the overall trend is towards large-scale, intensive, ecological, specialized, automated, and intelligent production. This change in production methods has promoted the overall animal husbandry to a more efficient modern production model. Sampling tubes play a vital role in animal husbandry production. Sampling tubes are used to collect samples from livestock or production environments for disease detection, health monitoring, nutritional analysis, and production performance evaluation. However, there are still deficiencies in the current automated production of sampling tubes, especially in the feeding of sampling tubes.

[0003] The sampling tube usually has a long tubular structure with an open end and a hollow interior, and a terminal cap is provided inside one end to close the tube body.

[0004] The existing method of discharging sampling tubes usually uses a hopper as a discharging mechanism. The existing hopper is composed of four vertical plates in front, back, left and right and a bottom plate, forming a hopper with an opening at the top. The plate is usually set at an angle, with the rear end higher than the front end. There is a strip-shaped discharge port at the lower end of the front vertical plate, and the strip-shaped discharge port is set horizontally. When discharging, multiple samples are placed in the hopper from the top opening, and then the sampling tubes are rolled along the bottom plate to the discharge port, so that the sampling tubes are continuously discharged from the discharge port to complete the discharging.

[0005] However, this continuous feeding method is not applicable in certain specific situations. For example, in the process of packaging sampling tubes, the sampling tubes need to be sent to the packaging station one by one. After one sampling tube is packaged, the second sampling tube is sent. If the continuous feeding method is adopted, multiple sampling tubes will be piled up at the packaging station, which will make it impossible to package each sampling tube separately.

[0006] The existing hopper can only meet the needs of continuous and fine material discharge, but some occasions require material discharge one by one. For example, when packaging sampling tubes, the material discharge mechanism needs to send the sampling tubes one by one to the packaging station. After packaging one sampling tube, the second sampling tube is sent. If the material is discharged continuously, there will be multiple sampling tubes at the packaging station, and it is impossible to package each sampling tube.

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

[0008] The purpose of the present invention is to provide a pipe feeding mechanism to solve the above-mentioned problems, wherein the mechanism can feed pipes one by one.

[0009] The technical solution adopted by the present invention is as follows: A pipe material unloading mechanism comprises a scraper, a baffle plate mounting member, a baffle plate and a receiving tray; The scraper and the baffle plate mounting member are arranged vertically, and the gap between the scraper and the baffle plate mounting member constitutes a material discharge channel; the lower end of the scraper is lower than the lower end of the baffle plate mounting member; The baffle plate is arc-shaped, the upper end of the baffle plate is rotatably arranged on the front of the baffle plate mounting member, and the lower end can bypass the lower end of the baffle plate mounting member to block the outlet of the material discharge channel; the upper end of the baffle plate is connected to the baffle plate driving mechanism, and the baffle plate driving mechanism is used to drive the baffle plate to rotate; The receiving tray is horizontally arranged below the material discharge channel; the receiving tray is connected to a receiving tray driving mechanism, and the receiving tray driving mechanism is used to drive the receiving tray to move forward and backward; When the baffle plate driving mechanism drives the baffle plate to rotate forward to open the outlet of the material discharge channel, the receiving tray driving mechanism drives the receiving tray to move forward to receive the pipes coming out of the material discharge channel; When the baffle plate driving mechanism drives the baffle plate to rotate backward to close the outlet of the material discharge channel, the receiving tray driving mechanism drives the receiving tray to move backward so that the lower end of the scraper scrapes the pipe off the front end of the receiving tray.

[0010] Furthermore, the front end of the receiving tray is bent upward to form a rib; the height of the rib is smaller than the diameter of the pipe.

[0011] Furthermore, the distance between the lower end of the scraper and the receiving tray is smaller than the diameter of the pipe.

[0012] Furthermore, the distance between the lower end of the baffle plate mounting piece and the receiving tray is greater than the diameter of the pipe and less than 2 times the diameter of the pipe.

[0013] Furthermore, the scraper and baffle plate mounting parts are fixedly arranged on the frame; a slide is arranged under the receiving tray, and the receiving tray is arranged on the slide through a guide rail; a power shaft is rotatably arranged 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, so that the baffle plate driving mechanism drives the baffle plate to rotate, and the power shaft transmits power to the receiving tray driving mechanism, so that the receiving tray driving mechanism drives the receiving tray to move back and forth on the slide.

[0014] Furthermore, a baffle plate rotating shaft is arranged on the front of the baffle plate mounting member, and the baffle plate rotating shaft is arranged horizontally and rotatably arranged on the front of the baffle plate mounting member; the upper end of the baffle plate is fixedly arranged on the baffle plate rotating shaft; The power shaft is horizontally arranged, rotatably arranged on the frame, and parallel to the rotating shaft of the baffle plate; 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 arranged 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 arranged at the other end of the rocker arm and contacts with 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, and the rocker arm return spring provides an upward pulling force, so that the rocker arm drives the baffle plate to rotate backward.

[0015] Furthermore, the receiving tray driving mechanism includes a receiving tray cam, a pull rod, a pull rod guide wheel and a pull rod return spring; The receiving tray cam is arranged 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 arranged at the rear end of the pull rod, the pull rod guide wheel contacts the receiving tray cam, and the pull rod guide wheel is located behind the receiving tray cam; The rear end of the pull rod reset spring is connected to the rear end of the pull rod, and the front end of the pull rod reset spring is connected to the frame; the pull rod reset spring provides a horizontal forward pulling force, so that the pull rod pushes the receiving tray to move forward.

[0016] Furthermore, the protrusions of the baffle plate cam and the receiving tray cam differ by 180°.

[0017] Furthermore, the material blocking plate mounting member is a vertically arranged flat plate or a skeleton structure composed of a plurality of cross bars and vertical plates.

[0018] Furthermore, the frame includes a left vertical plate and a right vertical plate; the left vertical plate and the right vertical plate are vertically arranged and parallel to each other; the scraper is fixedly arranged at the front end of the left vertical plate and the right vertical plate; the baffle plate mounting piece is located in front of the scraper, and the left and right ends of the baffle plate mounting piece are respectively connected to the left and right vertical plates through connecting rods; the left end of the power shaft is rotatably arranged on the left vertical plate, and the right end of the power shaft is rotatably arranged on the right vertical plate.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: In the present invention, the baffle plate blocks the outlet of the material discharge channel to prevent the pipes from falling continuously, while the receiving tray and the scraper cooperate to ensure the discharge of pipes one by one. When the receiving tray receives multiple pipes, the pipes will be laid flat on the receiving tray. The pipes are laid on the receiving tray, so when the receiving tray retreats, the lower end of the scraper will touch the pipes and push the pipes to move toward the front end of the receiving tray, so that the pipes close to the front end of the receiving tray fall out first. If the receiving tray continues to retreat, the pipes at the back will also fall out from the front end of the receiving tray in turn, thus completing the discharge of pipes one by one.

[0020] When the inlet of the material discharge channel in the pipe material discharge mechanism of the present invention is connected with the discharge port of the existing material discharge hopper, the problem that the existing hopper cannot discharge pipes one by one can be solved.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figures 1 to 4 As shown, the present invention discloses a pipe material feeding mechanism, which can be used for feeding pipes such as sampling pipes, and the pipe material feeding mechanism comprises a scraper 1, a baffle plate mounting member 2, a baffle plate 3 and a receiving tray 4; The scraper 1 and the baffle plate mounting member 2 are arranged vertically, and the gap between the scraper 1 and the baffle plate mounting member 2 constitutes a material discharge channel; the inlet of the material discharge channel is located at the upper end, the outlet of the material discharge channel 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 member 2; The baffle plate 3 is arc-shaped, the upper end of the baffle plate 3 is rotatably arranged on the front of the baffle plate mounting member 2, and the lower end can bypass the lower end of the baffle plate mounting member 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, and the baffle plate 3 driving mechanism is used to drive the baffle plate 3 to rotate; The receiving tray 4 is horizontally arranged below the material discharge channel; the receiving tray 4 is connected to a receiving tray 4 driving mechanism, and the receiving tray 4 driving mechanism is used to drive the receiving tray 4 to move forward and backward; like Figure 1 As shown, the discharge hopper 6 is arranged above the pipe discharge mechanism. When the pipe in the discharge hopper 6 enters the discharge channel from the upper end of the discharge channel, when the baffle plate 3 driving mechanism drives the baffle plate 3 to rotate forward, that is, rotate counterclockwise, so that the discharge channel outlet is opened, the receiving tray 4 driving mechanism drives the receiving tray 4 to move forward, so that the pipe coming out of the discharge channel can be received; when the baffle plate 3 driving mechanism drives the baffle plate 3 to rotate backward, that is, rotate clockwise, so that the discharge channel outlet is closed, the receiving tray 4 driving mechanism drives the receiving tray 4 to move backward, so that the lower end of the scraper 1 scrapes the pipe from the front end of the receiving tray 4.

[0029] In the above structure, the baffle plate 3 blocks the outlet of the material discharge channel to prevent the pipes from falling continuously, while the receiving tray 4 and the scraper 1 cooperate to ensure the discharge of pipes one by one. When the receiving tray 4 receives multiple pipes, the pipes will be laid flat on the receiving tray 4. The pipes are laid on the receiving tray 4, so when the receiving tray 4 retreats, the lower end of the scraper 1 will touch the pipes and push the pipes to move forward to the front end of the receiving tray 4, so that the pipes close to the front end of the receiving tray 4 fall out first. If the receiving tray 4 continues to retreat, the pipes arranged at the back will also fall out from the front end of the receiving tray 4 in turn, thus completing the discharge of pipes one by one.

[0030] In actual use, the opening and closing time of the outlet of the material discharge channel can be controlled according to the material discharge speed of the pipe in the material discharge channel to ensure that there is only one pipe on the receiving tray 4.

[0031] When the inlet of the material discharge channel in the pipe material discharge mechanism of the present invention is connected with the discharge port of the existing material discharge hopper 6, the problem that the existing hopper cannot discharge pipes one by one can be solved.

[0032] In the present invention, the lower end of the scraper 1 is lower than the lower end of the baffle plate mounting member 2; this is to ensure that the lower end of the scraper 1 can touch the pipe. The lower end of the baffle plate mounting member 2 is higher to ensure that there is enough space at the lower end of the baffle plate mounting member 2 so that the lower end of the baffle plate 3 can pass through, making it convenient for the lower end of the baffle plate 3 to block the outlet of the discharge channel. At the same time, it can also prevent the pipe from being scraped off the receiving tray 4 when the baffle plate 3 rotates forward.

[0033] In order to ensure that the scraper 1 can scrape off the pipe and facilitate the movement of the baffle plate 3 to prevent the baffle plate 3 from scraping off the pipe; the distance between the lower end of the scraper 1 and the receiving tray 4 is smaller than the diameter of the pipe, the distance between the lower end of the baffle plate mounting part 2 and the receiving tray 4 is larger than the diameter of the pipe and smaller than 2 times the diameter of the pipe, and the distance between the lower end of the baffle plate 3 and the receiving tray 4 is larger than the diameter of the pipe.

[0034] Furthermore, the front end of the receiving plate 4 is bent upward to form a rib, the height of which is smaller than the diameter of the pipe. Due to the existence of the rib, the pipe can be prevented from rolling down directly.

[0035] Furthermore, the scraper 1 and the baffle plate mounting member 2 are fixedly arranged on the frame; a slide 5 is arranged below the receiving tray 4, and the receiving tray 4 is arranged on the slide 5 through a guide rail; a power shaft 19 is rotatably arranged on the frame, and the driving mechanism of the baffle plate 3 and the driving mechanism of the receiving tray 4 are connected to the power shaft 19; the power shaft 19 transmits power to the driving mechanism of the baffle plate 3, so that the driving mechanism of the baffle plate 3 drives the baffle plate 3 to rotate, and the power shaft 19 transmits power to the driving mechanism of the receiving tray 4, so that the driving mechanism of the receiving tray 4 drives the receiving tray 4 to move forward and backward on the slide 5. The power shaft 19 is connected to a driving motor, and the driving motor is used to drive the power shaft 19 to rotate. The driving motor can be arranged on the frame.

[0036] If the driving mechanism of the baffle plate 3 and the driving mechanism of the receiving tray 4 work independently, if one of them starts a little slowly, the baffle plate 3 and the receiving tray 4 cannot work together accurately, resulting in the inability to accurately discharge the materials. For example, if the driving mechanism of the receiving tray 4 starts a little slowly, the receiving tray 4 will not catch the pipe, and the pipe will fall directly. In the present invention, the driving mechanism of the baffle plate 3 and the driving mechanism of the receiving tray 4 are both connected to the power shaft 19, so the driving mechanism of the baffle plate 3 and the driving mechanism of the receiving tray 4 can be linked, and can be started and stopped at the same time, ensuring that the baffle plate 3 and the receiving tray 4 can also be linked to each other, so that they can work more accurately.

[0037] Further, such as Figure 3 As shown, a baffle plate rotating shaft 7 is arranged on the front of the baffle plate mounting member 2, and the baffle plate rotating shaft 7 is arranged horizontally and rotatably arranged on the front of the baffle plate mounting member 2; the upper end of the baffle plate 3 is fixedly arranged on the baffle plate rotating shaft 7; The power shaft 19 is horizontally arranged, rotatably arranged on the frame, and parallel to the baffle plate rotating shaft 7; The driving mechanism of the baffle plate 3 includes a baffle plate cam 11, a rocker rod 9, a rocker rod guide wheel 10 and a rocker rod return spring 13; the baffle plate cam 11 is arranged on the power shaft 19, one end of the rocker rod 9 is connected to the baffle plate rotating shaft 7, and the rocker rod guide wheel 10 is arranged at the other end of the rocker rod 9 and contacts with the baffle plate cam 11; the lower end of the rocker rod return spring 13 is connected to the rocker rod 9, and the upper end of the rocker rod return spring 13 is connected to the frame, and the rocker rod return spring 13 provides an upward pulling force, so that the rocker rod 9 drives the baffle plate 3 to rotate backward.

[0038] When the baffle plate cam 11 rotates clockwise, the convex part of the baffle plate cam 11 contacts the rocker guide wheel 10, pressing the left end of the rocker 9 downward. At this time, the baffle plate 3 rotates forward to open the outlet of the material discharge channel. After the convex part of the baffle plate cam 11 rotates, the rocker return spring 13 provides an upward pulling force to pull the left end of the rocker 9 upward. At this time, the baffle plate 3 rotates backward to close the outlet of the material discharge channel.

[0039] Furthermore, the driving mechanism of the receiving tray 4 includes a receiving tray cam 18, a pull rod 15, a pull rod guide wheel 16 and a pull rod return spring 17; The receiving tray cam 18 is arranged on the power shaft 19, the front end of the pull rod 15 is connected to the rear end of the receiving tray 4, and a pull rod guide wheel 16 is arranged at the rear end of the pull rod 15. The pull rod guide wheel 16 is in contact with the receiving tray cam 18, and the pull rod guide wheel 16 is located behind the receiving tray cam 18; the rear end of the pull rod reset spring 17 is connected to the rear end of the pull rod 15, and the front end of the pull rod reset spring 17 is connected to the frame; the pull rod reset spring 17 provides a horizontal forward pulling force, so that the pull rod 15 pushes the receiving tray 4 to move forward.

[0040] Since the pull rod guide wheel 16 is located behind the receiving tray cam 18, when the receiving tray cam 18 rotates clockwise, the convex part of the receiving tray cam 18 contacts the pull rod guide wheel 16, pushing the pull rod 15 to move backward, causing the receiving tray 4 to move backward; after the convex part of the receiving tray cam 18 rotates, 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.

[0041] In the present invention, the protrusions of the baffle plate cam 11 and the receiving tray cam 18 differ by 180°. This ensures that when the outlet of the material discharge channel is opened, the receiving tray 4 moves forward, and when the outlet of the material discharge channel is closed, the receiving tray 4 moves backward.

[0042] like Figure 3 As shown, the frame includes a left vertical plate 12 and a right vertical plate 14; the left vertical plate 12 and the right vertical plate 14 are vertically arranged and parallel to each other; the scraper 1 is fixedly arranged at the front end of the left vertical plate 12 and the right vertical plate 14; the baffle plate mounting member 2 is located in front of the scraper 1, and the left and right ends of the baffle plate mounting member 2 are respectively connected to the left vertical plate 12 and the right vertical plate 14 through a connecting rod 8; the baffle plate mounting member 2 is a vertically arranged flat plate or a skeleton structure composed of a plurality of cross bars and vertical plates, Figure 3 In the embodiment, the baffle plate mounting member 2 is a skeleton structure.

[0043] The left end of the power shaft 19 is rotatably arranged on the left vertical plate 12, and the right end of the power shaft 19 is rotatably arranged on the right vertical plate 14. The baffle plate cam 11 is arranged at the end of the power shaft 19, such as Figure 3 As shown, the baffle plate cam 11 is arranged at the left end of the power shaft 19, and is located outside the left vertical plate 12. The swing rod 9 and the swing rod return spring 13 are both located outside the left vertical plate 12, and the upper end of the swing rod return spring 13 is connected to the outside of the left vertical plate 12. The receiving tray 4, the slide seat 5 and the receiving tray cam 18 are located between the left vertical plate 12 and the right vertical plate 14.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
