Description

Technical Field

[0001] This utility model relates to a small cap-opening machine for blood collection tubes. Background Technology

[0002] like Figure 9 As shown, the blood collection tube includes a blood collection tube body 50 and a blood collection tube cap 51 covering the upper end of the blood collection tube body 50. We need to quickly pull multiple blood collection tube caps 51 off the blood collection tube body 50. Existing small blood collection tube cap openers have low opening efficiency. They need to clamp the blood collection tube body 50 first and then open it through the blood collection tube cap opener. The two actions are not synchronized, resulting in a slow overall opening rhythm and low efficiency. The clamping device of some cap openers relies on a rigid structure for clamping, which is prone to unstable clamping, slippage, or damage to the blood collection tube due to slight differences in the outer diameter of different batches of blood collection tubes. Improvements and optimizations are made to address these issues. Utility Model Content

[0003] To solve the above problems, the technical problem to be solved by this utility model is to provide a small capping machine for blood collection tubes.

[0004] The technical solution of this utility model of a small blood collection tube cap opener is characterized by: a cap opener base, a blood collection tube clamping device fixed on the cap opener base, and a blood collection tube cap opening device movably mounted on the cap opener base. The blood collection tube clamping device includes a first clamping component and a second clamping component, forming a clamping docking channel for inserting the blood collection tube between the first clamping component and the second clamping component. Both the first clamping component and the second clamping component include a clamping plate assembly, clamping plate positioning seat assemblies located at the front and rear ends of the clamping plate assembly, and clamping plate outer limiting blocks located outside the clamping plate assembly and fixed on the cap opener base. The clamping plate positioning seat assembly includes a clamping plate positioning seat and a roller. The clamping plate positioning seat is provided with a positioning seat docking groove. The roller is rotatably disposed in the positioning seat docking groove. The clamping plate assembly includes a clamping plate, a clamping bar detachably disposed on the inner side of the clamping plate, and a drive wheel. The clamping plate has clamping plate guide protrusions at both ends that dock with the positioning seat docking groove and are positioned above the roller. The clamping bar is provided with an arc-shaped clamping groove for clamping the blood collection tube body. The clamping plate drive blocks are spaced apart on the outer side of the clamping plate. The clamping plate drive blocks are provided with drive block mating interfaces. The drive wheel is rotatably disposed at the drive block mating interface via a connecting shaft. The blood collection tube cap opening device includes a movable plate, a cap opening assembly fixed on the movable plate, and a linkage plate spaced at the left and right ends of the cap opening assembly and connected to the drive wheel. The lower inner side of the linkage plate is provided with a linkage plate inclined guide surface for driving the drive wheel to rotate. The cap opening assembly includes two symmetrically arranged cap opening blocks, and a tapered cap opening hole is formed between the two cap opening blocks for opening the blood collection tube cap. The diameter of the tapered cap opening hole is smaller at the upper end and larger at the lower end.

[0005] A tolerance gap is provided between the two opening blocks to facilitate fine-tuning when the blood collection tube cap is inserted.

[0006] The clamping plate positioning seat assembly includes two rollers.

[0007] The clamping strip is made of rubber.

[0008] The advantages of this utility model of a small blood collection tube opening machine are: through the cooperation between the inclined guide surface of the linkage plate and the drive wheel, the clamping plate assembly can be automatically driven to retract during the descent of the opening device, so as to realize the synchronous clamping of the blood collection tube body. This eliminates the need for the two-step operation of "clamping first and then opening the cap" in the traditional device, which significantly improves the opening efficiency and linkage.

Detailed Implementation

[0011] like Figure 1-9As shown, the present invention relates to a small blood collection tube opening machine, comprising an opening machine base 1, a blood collection tube clamping device 2 fixed on the opening machine base 1, and a blood collection tube opening device 3 movably mounted on the opening machine base 1. The blood collection tube clamping device 2 includes a first clamping component 5 and a second clamping component 6, and a clamping docking channel 7 for inserting the blood collection tube is formed between the first clamping component 5 and the second clamping component 6. Both the first clamping component 5 and the second clamping component 6 include a clamping plate assembly 10. The clamping plate assembly 10 includes clamping plate positioning seat assemblies 9 located at its front and rear ends, and clamping plate outer limiting blocks 11 located on the outside of the clamping plate assembly 10 and fixed to the cover opening machine base 1. The clamping plate positioning seat assembly 9 includes a clamping plate positioning seat 12 and rollers 13. The clamping plate positioning seat 12 has a positioning seat mating groove 14, and the rollers 13 are rotatably disposed within the positioning seat mating groove 14. The clamping plate assembly 10 includes a clamping plate 16, a clamping strip 17 detachably disposed inside the clamping plate 16, and a belt... The device includes a driving wheel 23, clamping plates 16 with clamping plate guide protrusions 19 at both ends that mate with the positioning seat grooves 14 and are positioned above the rollers 13, clamping bars 17 with arc-shaped clamping grooves 18 for clamping the blood collection tube body 50, clamping plate driving blocks 20 spaced apart on the outer side of the clamping plate 16, and driving block mating interfaces 21 on the clamping plate driving blocks 20. The driving wheel 23 is rotatably mounted at the driving block mating interfaces 21 via a connecting shaft 22. The blood collection tube opening device 3 includes a moving plate 25. The opening assembly 26 is fixed on the moving plate 25, and the linkage plate 27 is spaced apart at the left and right ends of the opening assembly 26 and connected to the drive wheel 23. The lower inner side of the linkage plate 27 is provided with a linkage plate inclined guide surface 29 for driving the drive wheel 23 to rotate. The opening assembly 26 includes two symmetrically arranged opening blocks 30. A conical opening hole 32 is formed between the two opening blocks 30 for opening the blood collection tube cap 51. The diameter of the conical opening hole 32 is smaller at the upper end and larger at the lower end. Through the mutual cooperation between the linkage plate inclined guide surface 29 of the linkage plate 27 and the drive wheel 23, the clamping plate assembly 10 can be automatically driven to retract during the descent of the opening device, so as to realize the synchronous clamping of the blood collection tube body 50. The two-step operation of "clamping first and then opening" in the traditional device is eliminated, which significantly improves the opening efficiency and linkage.

[0012] A tolerance gap 31 is provided between the two opening blocks 30 to facilitate fine adjustment when the blood collection tube cap is inserted. This gap can absorb slight size deviations and placement deviations of the blood collection tube cap 51, and avoid errors that prevent it from being successfully inserted into the conical opening hole 32. This significantly improves the tolerance rate and stability of the entire opening process.

[0013] The clamping plate positioning seat assembly 9 includes two rollers 13.

[0014] The clamping strip 17 is made of rubber, which can provide a flexible fit to blood collection tubes 50 from different batches and with slight size differences when clamping, ensuring stable clamping and preventing slippage, while avoiding the risk of damage caused by hard clamping.

[0015] Workflow: The blood collection tube rack containing the blood collection tubes is pushed into the clamping docking channel 7 of the blood collection tube clamping device 2. The blood collection tube opening device 3 moves from top to bottom on the opening machine base 1. After the inclined guide surface 29 of the linkage plate 27 contacts the drive wheel 23 of the clamping plate assembly 10, the drive wheel 23 pushes the clamping plate assembly 10 to retract inward, thereby causing the arc clamping groove 18 of the clamping bar 17 to clamp the blood collection tube body 50 of the blood collection tube. At the same time, the conical opening hole 3 of the opening assembly 26... 2. Moving downwards, due to its conical structure, it is easy for the blood collection tube cap 51 to pass through and be inserted into the conical opening hole 32. When the blood collection tube opening device 3 moves from bottom to top on the opening machine base 1, the blood collection tube body 50 is clamped, and the blood collection tube cap 51 is separated from the blood collection tube body 50 by the clamping force of the opening component 26, thus opening the cap. The opening block tolerance gap 31 can improve the tolerance rate (slight error in the size of the blood collection tube cap 51 makes it difficult to pass through from below the conical opening hole 32).

[0016] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model are included within the protection scope of the present utility model.
