Description

Technical Field

[0001] The utility model relates to the technical field of blood glucose meter test paper processing, in particular to a cutting mechanism used in a blood glucose meter test paper preparation machine. Background Art

[0002] A blood glucose tester is an instrument that measures the blood glucose concentration in the blood. It is an essential medical instrument for diabetic patients who need to regulate their blood glucose levels. Blood glucose test strips are usually consumables used in conjunction with blood glucose testers. The test strips are coated with biological enzymes, and the amount of glucose in the peripheral blood can be tested by dropping them into the blood and observing their color changes.

[0003] For example, the prior art CN220807520U discloses a cutting mechanism for a blood glucose meter test strip trimmer, comprising a cutting fixed frame, on which a lower knife assembly and a power assembly are provided, the lower knife assembly is used to place the product to be cut, an upper knife assembly is provided on the output end of the power assembly, the power assembly can drive the upper knife assembly to connect with the lower knife assembly, the upper knife assembly is provided with a material pressing assembly, and the material pressing assembly is used to limit the product on the lower knife assembly.

[0004] The test strips are originally long and have a certain toughness, so a whole test strip needs to be cut into several small strips of equal length. At present, there is a lack of cutting mechanisms specifically used for blood glucose meter test strips on the market. Most of them are positioned by simple tools and then cut manually, resulting in low cutting efficiency and uneven cutting quality. In addition, the labor intensity of manual cutting is relatively high, resulting in increased labor costs. Utility Model Content

[0005] In view of this, an object of the present invention is to provide a cutting mechanism for a blood glucose meter test strip preparation machine to solve the shortcomings existing in the prior art.

[0006] To achieve the above purpose, the utility model adopts the following contents:

[0007] A cutting mechanism for a blood glucose meter test strip preparation machine comprises a horizontally arranged machine platform, a limit slot is provided in the middle of the surface of the machine platform along its length direction, a clamping part of a displacement push block is connected in a plug-in manner in the limit slot, a displacement drive component is arranged below the surface of the machine platform, the clamping part of the displacement push block is downwardly connected to the output end of the displacement drive component, and the displacement drive component realizes the reciprocating linear motion of the displacement push block relative to the limit slot;

[0008] A cutting knife group is arranged on one side of the surface of the machine table, and the cutting knife group comprises an upper knife that can move up and down, a fixed lower knife and a lifting drive cylinder for driving the upper knife to approach or move away from the lower knife, and the knife surface of the lower knife is flush with the surface of the machine table; a downward inclined material discharge chute is also arranged outside one side of the machine table, and the material discharge chute is located below the plane where the knife surface of the lower knife is located.

[0009] Further explanation, the surface of the machine also protrudes with two limit stop bars along its length direction, and the two limit stop bars are symmetrically arranged with the center line of the limit card slot as the center. By adding limit stop bars on both sides, it is ensured that in the process of pushing the test strip by the displacement push block, the problem of the test strip deviating to the left and right and affecting the cutting effect is avoided, and the cutting edge of the test strip is ensured to be flat and neat.

[0010] Further explanation: the displacement drive assembly includes a guide shaft, a slider, a driven wheel, a driving wheel, a synchronous belt, and a rotating motor. The guide shaft is arranged on the bottom end face of the machine along the length direction of the machine. The slider is movably sleeved on the guide shaft and upwardly connected to the clamping portion of the displacement push block. The driven wheel and the driving wheel are arranged on the bottom end face of the machine in parallel and rotatably. The synchronous belt is wound between the driven wheel and the driving wheel, and one side of the synchronous belt is connected to the slider. The rotating motor is arranged on the bottom end face of the machine and its output end is connected to the driving wheel. Based on this technical solution, the rotating motor drives the driving wheel to rotate, thereby linking the driven wheel to realize the reciprocating transmission action of the synchronous belt, and the synchronous belt drives the slider to move forward and backward, thereby realizing the forward and backward movement of the displacement push block, and finally the displacement push block completes the action of smoothly pushing the test strip toward the cutting tool.

[0011] Further explanation: the cutting knife group also includes a top plate, a middle plate, and a bottom plate arranged in sequence from top to bottom; the top plate and the bottom plate are fixedly connected by a guide column, and the middle plate can be movably sleeved on the guide column through a guide sleeve; the upper tool blade is arranged on the side of the middle plate with the blade facing downward, and the lower tool blade is arranged on the bottom plate with the blade facing upward, and the upper tool and the lower tool can be staggered up and down; the lifting drive cylinder is arranged on the top plate, and the output end of the lifting drive cylinder is connected downward to the middle plate. Based on this technical solution, the lifting drive cylinder drives the middle plate to move up and down, thereby realizing the up and down movement of the upper tool, and then realizing the staggering or separation of the upper tool and the lower tool, completing the cutting action of the test strip.

[0012] The upper cutter is arranged on the side of the middle plate in an inclined posture. The inclined surface can effectively reduce the friction between the upper cutter and the lower cutter when they are in contact, reduce the tangential force and vibration during the cutting process, and thus ensure the cutting quality and integrity of the test paper.

[0013] The bottom end surface of the top plate is protruded downwards and provided with two in-position posts of the same length. The in-position posts limit the middle plate from continuing to move upwards, and when the middle plate abuts against the in-position posts, it indicates that the upper cutter and the lower cutter have completed the separation action.

[0014] Wherein, a protective shell is arranged on the upper part of the cutting knife set, which can protect the cutting knife set from being disturbed by external substances, making the cutting knife set more durable.

[0015] Compared with the prior art, the beneficial effect of the utility model is that the utility model controls the displacement push block through the displacement drive component to gradually push the test strip placed on the surface of the machine table toward the cutting knife group, thereby realizing automatic feeding of the test strip, and then setting the upper knife to cooperate with the lower knife to cut the test strip extending between the two, thereby realizing automatic cutting of the blood glucose meter test strip, greatly improving the processing efficiency and reducing the labor intensity of the operator.

Those skilled in the art should understand that the following specific description is illustrative rather than restrictive, and should not be used to limit the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, the embodiment of the utility model proposes a cutting mechanism for a blood glucose meter test strip preparation machine, including a horizontally arranged machine table 1, a limit card slot 11 is provided in the middle of the surface of the machine table 1 along its length direction, a card portion 21 of a displacement push block 2 is connected in a plug-in manner in the limit card slot 11, a displacement drive component 3 is arranged below the surface of the machine table 1, the card portion of the displacement push block 2 is downwardly connected to the output end of the displacement drive component 3, and the displacement drive component 3 realizes the reciprocating linear motion of the displacement push block 2 relative to the limit card slot 11.

[0025] A cutting knife group 4 is arranged on one side of the surface of the machine table 1. The cutting knife group 4 has an upper knife 41 that can move up and down, a fixed lower knife 42, and a lifting drive cylinder 43 for driving the upper knife 41 to approach or move away from the lower knife 42. The knife surface of the lower knife 42 is flush with the surface of the machine table 1; a downwardly inclined material discharge chute 5 is also arranged on the outside of one side of the machine table 1, and the material discharge chute 5 is located below the plane where the knife surface of the lower knife 42 is located.

[0026] First, the displacement drive component controls the displacement push block to gradually push the test strip placed on the machine surface to the cutting knife group to realize automatic feeding of the test strip, and then the upper knife is set to cooperate with the lower knife to cut the test strip inserted between the two, thereby realizing automatic cutting of the blood glucose meter test strip, and the cut small test strip is collected through the unloading chute. In this way, the automatic cutting of the blood glucose meter test strip is realized, which greatly improves the processing efficiency and reduces the labor intensity of the operator.

[0027] In one embodiment, the surface of the machine 1 is also protruded with two limit bars 12 along its length direction. The two limit bars 12 are symmetrically arranged with the center line of the limit slot 11 as the center. In actual design, the width of the displacement push block is smaller than the spacing between the two limit bars to avoid the limit bars affecting the normal movement of the displacement push block. By adding limit bars on both sides, it is ensured that in the process of the displacement push block pushing the test strip, the problem of the test strip being offset to the left and right and affecting the cutting effect is avoided, and the cutting edge of the test strip is ensured to be flat and neat.

[0028] In this embodiment, the displacement drive assembly 3 includes a guide shaft 31, a slider 32, a driven wheel 33, a driving wheel 34, a synchronous belt 35, and a rotary motor 36. The guide shaft 31 is arranged on the bottom end surface of the machine 1 along the length direction of the machine 1. The slider 32 is movably sleeved on the guide shaft 31 and connected to the clamping portion of the displacement push block 2 upward. The driven wheel 33 and the driving wheel 34 are arranged on the bottom end surface of the machine 1 in parallel and rotatably. The synchronous belt 35 is wound between the driven wheel 33 and the driving wheel 34, and one side of the synchronous belt 35 is connected to the slider 32. The rotary motor 36 is arranged on the bottom end surface of the machine 1 and its output end is connected to the driving wheel 34. Based on this technical solution, the rotary motor drives the driving wheel to rotate, thereby linking the driven wheel to realize the reciprocating transmission action of the synchronous belt, and the synchronous belt drives the slider to move forward and backward, thereby realizing the forward and backward movement of the displacement push block, and finally the displacement push block completes the action of smoothly pushing the test strip toward the cutting tool.

[0029] In this embodiment, the cutting knife group 4 also includes a top plate 44, a middle plate 45, and a bottom plate 46 arranged in sequence from top to bottom. The top plate 44 and the bottom plate 46 are fixedly connected by a guide column 47, and the middle plate 45 is movably sleeved on the guide column 47 through a guide sleeve 48; the upper cutter 41 is arranged on the side of the middle plate 45 with the blade facing downward, and the lower cutter 42 is arranged on the bottom plate 46 with the blade facing upward, and the upper cutter 41 and the lower cutter 42 can be staggered up and down; the lifting drive cylinder 43 is arranged on the top plate 44, and the output end of the lifting drive cylinder 43 is connected downward to the middle plate 45. Based on this technical solution, the lifting drive cylinder drives the middle plate to move up and down, thereby realizing the up and down movement of the upper cutter, and then realizing the staggering or separation of the upper cutter and the lower cutter, and completing the cutting action of the test strip.

[0030] The upper cutter 41 is arranged in an inclined posture on the side of the middle plate 45. The inclined surface can effectively reduce the friction between the upper cutter and the lower cutter when they contact, reduce the tangential force and vibration during the cutting process, and thus ensure the cutting quality and integrity of the test paper.

[0031] The bottom end of the top plate 44 is protruded downwards and provided with two in-place posts 49 of the same length. The in-place posts limit the middle plate from continuing to move upwards, and when the middle plate abuts against the in-place posts, it indicates that the upper cutter and the lower cutter have completed the separation action.

[0032] Among them, the upper part of the cutting knife group 4 is provided with a protective shell 6. The protective shell can protect the cutting knife group from being disturbed by external substances, making the cutting knife group more durable.

[0033] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here.
