Description

Technical Field

[0001] The invention relates to a test bar processing technology, in particular to a test bar material dividing mechanism. Background Art

[0002] During the production process of test strips (such as blood glucose test strips), the raw material of the test strips is pushed between rolling cutters, which cut the raw material into individual test strips for packaging. The rolling cutters are typically formed by two staggered cylindrical blades, each with an annular blade and an annular rubber pad spaced at intervals. The annular rubber pad has an annular rubber groove in the center. The staggered shear force generated by the annular blades and annular rubber pad on the cylindrical blades creates a shear force. After the rolling cutters complete the shearing, the test strips fall into the distributor below, from which they fall into the feed channel, into the feed pipe, and then into the subsequent mechanism.

[0003] Existing distributors often have the problem of material jamming. Test strips are easily stuck in the distributor channel, which affects production efficiency. Summary of the Invention

[0004] The object of the present invention is to provide a test strip distributing mechanism which is not prone to material jamming.

[0005] The following is a brief summary of one or more aspects to provide a basic understanding of these aspects. This summary is not an exhaustive overview of all conceivable aspects and is neither intended to identify key or critical elements of all aspects nor to define the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that will be provided later.

[0006] According to one aspect of the present invention, a test strip dispensing mechanism is provided, comprising:

[0007] A support, wherein an upper mounting plate is provided on the support, and two groups of material channels are staggeredly provided on the upper mounting plate. The two groups of material channels are formed by two rows of staggered and spaced-apart material removal plates and material distribution plates, and each of the material distribution channels is provided with a material guide pipe connection structure;

[0008] A plurality of material guiding pipes are provided, and the upper ends of the material guiding pipes are sleeved on the material guiding pipe connecting structure.

[0009] In one embodiment, the material distribution channel includes an inlet section and a vertical section that are connected to each other, and the material guide pipe connection structure is connected to the end of the inlet section and extends into the vertical section.

[0010] In one embodiment, the material guide tube connection structure includes a first protrusion arranged on the inner surface of the material removal plate and a second protrusion arranged on the inner surface of the material separation plate, the first protrusion extends downward along the inner surface of the material removal plate, and the second protrusion extends downward along the inner surface of the material separation plate.

[0011] In one embodiment, the lower ends of the first protrusion and the second protrusion expand outward.

[0012] In one embodiment, the material guiding tube is made of Teflon.

[0013] In one embodiment, the cross-section of the material guiding tube is oblate.

[0014] In one embodiment, the mechanism further includes a lower mounting plate, on which are opened material guide tube limiting holes corresponding to the number and positions of the material distribution channels, and each of the material guide tubes passes through one of the material guide tube limiting holes.

[0015] In one embodiment, the ejector plate includes a first contact surface for contacting the annular rubber pad on the rolling cutter, and the first contact surface is provided with an ejector protrusion for inserting into the annular rubber groove on the rolling cutter.

[0016] In one embodiment, the material-removing protrusion is provided with a second contact surface for contacting the annular rubber groove on the rolling cutter.

[0017] In one embodiment, one side surface of the dividing plate is an arc surface for cooperating with the annular blade of the rolling cutter, and the other side surface of the dividing plate is a smooth inclined surface for guiding materials.

[0018] The beneficial effect of the embodiments of the present invention is that by providing a material guide tube connection mechanism within the material distribution channel and sleeve-engaging the upper end of the material guide tube with the connection mechanism, the problem of material jamming in the material distribution mechanism can be reduced. After the single test strip is cut and falls into the material distribution channel, it will directly enter the material guide tube, reducing the possibility of material jamming.

DETAILED DESCRIPTION

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Note that the various aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention.

[0026] like Figures 1 to 3 As shown, the present embodiment provides a test strip dispensing mechanism, comprising a support 1, an upper mounting plate 2 disposed on the support 1, and two sets of dispensing channels disposed on the upper mounting plate 2 in an offset manner. The two sets of dispensing channels are formed by two rows of staggered, spaced-apart, stripping plates and dispensing plates, each of which is provided with a material guide tube connection structure. The mechanism also includes a plurality of material guide tubes (not shown in the figure for clarity), the upper ends of which are sleeved on the material guide tube connection structure.

[0027] See also Figure 3 The material distribution channel 23 includes an inlet section 23a and a vertical section 23b. The material guide tube connection structure is connected to the end of the inlet section 23a and extends into the vertical section 23b. After the cut test strips fall into the inlet section 23a, they will fall directly into the material guide tube, thereby reducing the possibility of material jamming.

[0028] In this embodiment, the material guide tube connection structure includes a first protrusion 241 arranged on the inner surface of the material removal plate 21 and a second protrusion 242 arranged on the inner surface of the material separation plate 22. The first protrusion 241 extends downward along the inner surface of the material removal plate 21, and the second protrusion 242 extends downward along the inner surface of the material separation plate 22, so that the test strip can fall into the material guide tube without hindrance.

[0029] Preferably, the lower ends of the first protrusion 241 and the second protrusion 242 are expanded outward to ensure that the material guide tube is tightly sleeved and not easy to fall off. In this embodiment, the first protrusion 241 is inclined outward along the inner surface of the material removal plate 21, and the second protrusion 242 is thickened at the bottom to achieve outward expansion.

[0030] In order to ensure that the test strip slides smoothly, the guide tube should be made of a smooth material with a low friction coefficient. In this embodiment, the guide tube is made of Teflon material, and the cross-section of the guide tube is oblate (see the shape of the guide tube limiting hole 31), and the two straight edges of the guide tube are sleeved on the outside of the first protrusion 241 and the second protrusion 242.

[0031] The test strip distributing mechanism further comprises a lower mounting plate 3 , on which are provided guide tube limiting holes 31 corresponding to the number and position of the distributing channels. Each guide tube passes through a guide tube limiting hole 31 to ensure that the guide tubes are not tangled or disordered.

[0032] In order to pick out the test strips stuck in the glue groove of the rolling cutter rubber pad, the pick plate of the existing distributor is usually narrowed and thinned at the end to form a pick head. However, the length of the pick head is limited, and the angle between the pick head and the glue groove is large, resulting in poor picking effect. In addition, the pick head itself has a thin structure and a short service life.

[0033] Therefore, as a further improvement of this organization, see Figure 2 The pick plate 21 includes a first contact surface 21a for contacting the annular rubber pad on the rolling cutter. The first contact surface 21a is provided with a pick protrusion 211 for inserting into the annular rubber groove on the rolling cutter. The first contact surface 21a is a circular arc surface to mate with the annular rubber pad. Compared to existing pick heads, the pick protrusion 211 can cut into the annular rubber groove at a smaller angle, thereby improving the pick effect. In addition, the pick protrusion 211 itself has a structure similar to a rib, making it more robust than existing thin-sheet pick heads.

[0034] Preferably, the material removal protrusion 211 is provided with a second contact surface 211 a for contacting the annular glue groove on the rolling cutter. The second contact surface 211 a is also an arc surface to better fit the annular glue groove.

[0035] Similarly, one side surface of the dividing plate 22 is a circular arc surface 221 for cooperating with the annular blade of the rolling cutter, and the other side surface of the dividing plate 22 is a smooth inclined surface 222 for guiding the material. This part is the existing technology and will not be repeated here.

[0036] In summary, the test strip dispensing mechanism provided in the embodiments of the present application, by providing a guide tube connection mechanism within the dispensing channel and sleeve-engaging the upper end of the guide tube onto the connection mechanism, can reduce the problem of material jamming within the dispensing mechanism. After the individual test strips are cut and fall into the dispensing channel, they enter the guide tube directly, shortening the path where material jamming is likely to occur. By improving the structure of the ejector plate, better material removal can be achieved, and the service life of the ejector plate can be extended.

[0037] By installing a guide tube connection mechanism within the material distribution channel and sleeve-fitting the upper end of the guide tube onto this connection structure, the problem of material jamming in the distribution mechanism can be reduced. After the single test strip is cut and falls into the distribution channel, it will directly enter the guide tube, shortening the intermediate path where material jamming problems may occur.
