Description

Technical Field

[0001] The utility model belongs to the technical field of blood glucose meter test paper processing equipment, in particular to a cutting mechanism used for a blood glucose meter test paper trimmer. Background Art

[0002] Glucose in the blood is called blood sugar Glu. Glucose is an important component of the human body and an important source of energy. The normal human body needs a lot of sugar every day to provide energy and power the normal operation of various tissues and organs. Therefore, blood sugar must be maintained at a certain level to meet the needs of various organs and tissues in the body. A blood glucose meter is an electronic instrument that measures blood sugar levels. When blood sugar needs to be measured, the user inserts the test strip into the blood glucose meter through the test strip slot for testing, which is more common in daily life.

[0003] When processing test paper, the molded material roll needs to be processed into thin strips. There are currently two commonly used processing methods, namely stamping and cutting.

[0004] Prior art, such as a Chinese patent with announcement number 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.

[0005] However, there are certain technical problems with the power assembly in the above-mentioned prior art that is connected to the upper knife assembly and controls the movement of the upper knife assembly. The power assembly mainly pulls the cutting fixed frame up and down through the cutting cylinder, and the cutting cylinder is controlled by a controller. However, the precision of the cylinder is relatively low and cannot meet the high-precision cutting requirements. Moreover, the cylinder cannot perform continuous and regular up and down cutting actions. The cylinder control is relatively simple and unstable, and has a small scope of application. Utility Model Content

[0006] In view of this, an object of the present utility model is to provide a cutting mechanism for a blood glucose meter test strip trimmer, which is easy to use and has high stability.

[0007] To achieve the above purpose, the utility model adopts the following contents:

[0008] The utility model provides a cutting mechanism for a blood glucose meter test paper trimmer, which comprises:

[0009] A support base, with two spaced-apart parallel mounting frames on the top, a horizontal rotating motor is mounted on the outer mounting frame, a driving gear is mounted on the output end of the rotating motor, a bearing seat is mounted on the inner mounting frame, a horizontal rotating shaft is rotatably mounted in the bearing seat, a driven gear meshing with the driving gear is mounted on one end of the rotating shaft, a rotating wheel is mounted on the other end of the rotating shaft, and a hinge shaft is protruding on the surface of the rotating wheel;

[0010] A displacement seat, which is movably arranged on the outer side of the lower part of the support base through a vertical guide assembly, and an axis portion is arranged on the upper part of the displacement seat, and a connecting rod is movably and rotatably sleeved on the axis portion, and the other end of the connecting rod is rotatably connected to the hinge shaft;

[0012] A material swinging platform is arranged at one side of the bottom end of the supporting base, and a lower cutting knife is arranged at the front side of the material swinging platform, and the upper cutting knife can be staggered with the lower cutting knife up and down.

[0013] According to the cutting mechanism for the blood glucose meter test strip trimmer provided by the utility model, the bottom sides of the knife seat are each provided with a vertical downward extension rod, the two sides of the swinging platform are each provided with a pair of spaced mounting blocks, the side of the mounting block is provided with a rotatable guide wheel, and the extension rod is movably clamped between the wheel surfaces of the two guide wheels. In this way, when the knife seat moves up and down with the displacement seat, the extension rod at the bottom of the knife seat will slide relative to the two guide wheels, and the two guide wheels will limit the lateral direction of the extension rod, thereby ensuring the stability of the knife seat during vertical movement without shaking.

[0014] Furthermore, both sides of the extension rod are recessed with vertical slide grooves, and the guide wheel can roll up and down along the extension direction of the slide groove. In this way, during the relative sliding between the extension rod at the bottom of the knife seat and the two guide wheels, the guide wheel can just roll up and down along the opening direction of the slide groove, thereby ensuring the stability of the knife seat during vertical movement and preventing left and right deviation.

In this way, the displacement seat can achieve stable linear motion in the vertical direction through the relative sliding cooperation between the slider and the guide rail, ensuring the consistency of the displacement direction of the displacement seat during the up and down movement of the displacement seat driven by the linkage rod.

[0016] According to the cutting mechanism for a blood glucose meter test strip trimmer provided by the utility model, both ends of the linkage rod are provided with shaft sleeves, and the shaft sleeves and the hinge shaft, as well as the shaft sleeves and the shaft are rotationally connected via bearings. Thus, through the action of the shaft sleeves and the bearings, the stability of the linkage rod and the shaft or the linkage rod and the hinge shaft during relative rotation is ensured, and the friction force is reduced to ensure the rotation accuracy of the linkage rod.

[0017] According to the cutting mechanism for the blood glucose meter test strip trimmer provided by the utility model, the center line of the rotating motor and the center line of the rotating shaft are in the same vertical plane, and the driven gear and the driving gear are arranged up and down. The driving gear and the driven gear are arranged side by side, which has a certain effect of reducing the tooth error.

[0018] Compared with the prior art, the utility model has the following technical effects: the utility model has a simple structure and a reasonable design; the driving gear is controlled by a rotating motor to drive the driven gear to rotate clockwise or counterclockwise, so that the rotating shaft controls the upward or downward deflection of the rotating wheel, and then the rotating wheel drives the connecting rod connected to it to move upward or downward, so that the connecting rod drives the knife seat to move up and down, and finally the upper cutting knife and the lower cutting knife are staggered up and down to complete the cutting action of the test paper, and the above process is repeated continuously to realize the intermittent cutting of the material strips, so as to meet the production needs of assembly line cutting, the structural design is ingenious and reasonable, easy to use, fast cutting speed, and improved production efficiency.
