Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.
[0023] Example
[0024] Please refer to Figure 1 and Figure 2 This embodiment provides a test tube dispensing device, including a dispensing rack 50, on which a dispensing lever 424 is slidably mounted vertically; secondly, a lifting mechanism is provided on the dispensing rack 50, which raises or lowers the dispensing lever 424; thirdly, a dispensing transfer hopper 51, the size of which is slightly larger than the outer diameter of the test tube to be dispensed, the dispensing transfer hopper 51 is vertically mounted on the dispensing rack 50, the opening of the dispensing transfer hopper 51 faces downwards, and one side of the dispensing transfer hopper 51... The wall has an axially oriented tube outlet groove 511, the two ends of which respectively pass through the two ends of the tube outlet transfer bucket 51. The tube outlet lever 424 is located in the tube outlet groove 511 and moves up and down along the tube outlet groove 511. The tube outlet lever 424 is used to lift the test tube to be discharged in the tube outlet transfer bucket 51. The fourth part includes a tube outlet slide 52, which is located on the tube outlet frame 50 and above the tube outlet transfer bucket 51. It is connected to the top of the tube outlet transfer bucket 51, and the connection point is the highest point of the tube outlet slide 52.
[0025] This embodiment provides a test tube dispensing device. A dispensing rack 50 provides structural support. A dispensing transfer bucket 51 is installed on the dispensing rack 50 with its opening facing downwards. The dispensing transfer bucket 51 constructs and regulates the path of the test tubes to be dispensed, ensuring that the test tubes move only up and down along the inner wall of the dispensing transfer bucket 51. This effectively prevents rolling, collisions, or falls during the transfer process. Furthermore, a dispensing groove 511 is formed on the side wall of the dispensing transfer bucket 51, and a dispensing lever 424 is slidably installed vertically on the dispensing rack 50. The dispensing lever 424 inserts into the dispensing groove 511 and can slide up and down along the groove. The dispensing lever 424 contacts and supports the test tubes. The test tube to be dispensed is lifted from the bottom of the dispensing transfer hopper 51 and pushed up to the top of the dispensing transfer hopper 51 until it is pushed out from the top of the dispensing transfer hopper 51 and enters the dispensing slide 52. The connection between the dispensing transfer hopper 51 and the dispensing slide 52 is the highest point of the dispensing slide 52. Therefore, the test tube to be dispensed will slide along the dispensing slide 52 to its lowest point. On this basis, a lifting mechanism is set up to control the lifting and lowering of the dispensing lever 424. Through the cooperation of the above features, the test tube dispensing device can effectively solve the problem that the test tube is prone to rolling collision or falling during vertical transfer, which leads to the damage of the test tube.
[0026] To further explain the specific structure of the tube transfer hopper 51, the tube transfer hopper 51 is cylindrical, and the inner diameter of the tube transfer hopper 51 is slightly larger than the outer diameter of the test tube to be discharged; the length of the tube transfer hopper 51 is greater than the length of the test tube to be discharged.
[0027] It should be noted that the opening diameter of the funnel is larger than the inner diameter of the funnel body to facilitate the insertion of the test tube to be dispensed.
[0028] To further explain the specific structure of the lifting mechanism, the lifting mechanism includes a top roller 53, a bottom roller 54, and a lifting belt 55; the top roller 53 and the bottom roller 54 are respectively located at the top and bottom ends of the tube outlet frame 50, the axes of the top roller 53 and the bottom roller 54 are parallel and located in the same vertical plane, and the top roller 53 or the bottom roller 54 is driven by a lifting motor; the lifting belt 55 is wound around and supported by the top roller 53 and the bottom roller 53; the tube outlet frame 50 is slidably connected to a lifting seat 56 in the vertical direction, the lifting seat 56 is fixedly connected to the lifting belt 55, and the tube outlet lever 424 is located on the lifting seat 56.
[0029] To prevent the test tube pushed out by the tube ejector 424 from falling back into the tube transfer hopper 51, a pair of elastic limiting plates 512 are provided at the top of the tube transfer hopper 51. The two elastic limiting plates 512 are clamped against the side wall of the tube transfer hopper 51. When the elastic limiting plates 512 are in their natural state, the distance between the two elastic limiting plates 512 is slightly smaller than the outer diameter of the test tube to be ejected.
[0030] By setting elastic limiting plates 512, when the test tube to be discharged rises to the top of the discharge transfer hopper 51, the top of the test tube to be discharged first squeezes the two elastic limiting plates 512 outward, so that the two elastic limiting plates 512 move away from each other until the entire test tube to be discharged is squeezed out between the two elastic limiting plates 512. Then the two elastic limiting plates 512 are reset, and the distance between them is slightly smaller than the outer diameter of the tube body of the test tube to be discharged, so as to prevent the test tube to be discharged from falling back into the discharge transfer hopper 51.
[0031] To facilitate the extrusion of the test tubes and further prevent the test tubes from falling back into the tube transfer hopper 51, the elastic limiting piece 512 is a vertical strip, and the top of the elastic limiting piece 512 is bent inward at an obtuse angle.
[0032] To prevent the test tubes to be discharged from falling out from both sides of the discharge slide 52 when they are lifted out to the discharge slide 52, the discharge slide 52 is provided with slide walls 521 on both sides, and the height of the slide walls 521 is greater than half the length of the test tubes to be discharged.
[0033] Preferably, in order to implement the diversion of the test tubes to be discharged, the tube discharge chute 52 is provided with multiple branches, and the highest points of the multiple branches intersect at the same point.
[0034] It should be noted that the destination of the test tubes to be dispensed can be manually intervened during use.
[0035] To achieve rigorous selection, there are two branch channels, which are located on the same vertical plane and extend in opposite directions; a channel divider 522 is hinged at the highest point of the outlet slide 52, and the hinge axis of the channel divider 522 is located directly above the top of the outlet transfer bucket 51.
[0036] By setting the channel divider 522, when in use, simply move the channel divider 522 to a specific angle so that one side completely covers the top of the tube transfer bucket 51, and the lifted test tube will be guided to slide to the corresponding branch.
[0037] To achieve electronic control, the hinge shaft of the lane divider 522 is connected to a lane divider motor.
[0038] Preferably, in order to avoid the test tubes from accumulating at the highest point of the tube exit slide 52, the slopes of the two branches are different, and the entrance width of the branch with a gentler slope is narrower than the exit width, and the width of the branch transitions smoothly.
[0039] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
