Description
Technical Field
[0001] The utility model relates to the technical field of test paper production equipment, in particular to a test paper material dividing and pushing mechanism. Background Art
[0002] Test strips are widely used and come in a variety of types, such as immunoassay strips, electrochemical test strips, dry chemical test strips, etc.
[0003] Since test papers are generally long and thin, in order to facilitate the processing of the test papers, they are generally first made into long strips of test papers, and then the long strips of test papers are cut into test papers of set specifications and then collected.
[0004] During the test strip cutting process, in order to meet the cutting requirements, the test strips are usually cut one by one. In the existing technology, in order to meet the position accuracy of the test strip loading, most of them are manually loaded one by one, which is slow and inefficient and cannot effectively guarantee the production cycle.
[0005] With the advancement of automation, automated equipment is also used to replace manual test strip loading. The stacked test strips are placed manually at the loading port, and then the pusher plate pushes the bottom test strips to load them one by one. However, in actual production operations, the separation between adjacent stacked test strips cannot be effectively guaranteed, resulting in more than one test strip being pushed out at the same time. There is also a situation where the stacked test strips cannot fall to the pusher plate in time, which seriously affects the automated production process. Utility Model Content
[0006] In order to solve the above problems, the present application provides a test paper distribution and pushing mechanism with a rational structure, which effectively reduces the contact area between the test paper and the wall of the accommodating space, reduces the resistance of the test paper to its own weight, and enables the stacked test paper to fall stably and smoothly, thereby ensuring the reliability of the test paper distribution and pushing.
[0007] The technical solutions adopted in this utility model are as follows:
[0008] A test paper dispensing and pushing mechanism comprises a working platform, a movable seat is installed on the working platform for forward and backward movement, support plates are installed on the working platforms on both sides of the movable seat, side plates are installed on the support plates, a front plate is installed between the side plates on both sides, the front plate is horizontally mounted above the movable seat, and rear plates are respectively installed on the rear parts of the side plates on both sides, and the side plates, front plate and rear plate together constitute a accommodating space for stacking test papers; a plurality of ribs are installed on the side of the front plate facing the accommodating space, and side baffles are installed on the side of the side plates facing the accommodating space, and the ribs and side baffles are in contact with the test papers.
[0009] As a further improvement of the above technical solution:
[0010] The rib plate comprises vertical bars which are installed at intervals on the side of the front plate along the left-right direction, and a transverse bar is installed on the front plate below the bottom end of the vertical bar.
[0011] The side surfaces of the transverse strips extend toward the interior of the accommodating space to form bulges, and the side surfaces of the bulges are indented by 0.1-0.5 mm relative to the side surfaces of the vertical strips.
[0012] The bottom end of the transverse strip extends downward and protrudes from the bottom surface of the front plate. The spacing between the bottom surface of the transverse strip and the top surface of the movable seat is greater than the thickness of a single test paper but less than the thickness of two test papers.
[0013] The movable seat behind the test paper is provided with an embedding groove along the left and right directions, in which an embedding block is embedded; the test paper is supported on the supporting surface of the movable seat in front of the embedding block, and the height of the embedding block is higher than the height of the supporting surface.
[0014] The height difference between the embedding block and the supporting surface is smaller than the thickness of a single piece of test paper.
[0015] The material hardness of the insert is greater than the material hardness of the movable seat.
[0016] The movable seat is provided with a plurality of long slots arranged at intervals from the front edge to the rear, and the long slots cut the embedding slot into a plurality of sections arranged at intervals on the left and right sides, and an embedding block of corresponding size is arranged in each section of the embedding slot.
[0017] A plurality of adsorption holes are provided on the supporting surface, and the adsorption holes are connected to an external air source.
[0018] A groove is formed downwardly on the edge of the top surface of the front plate.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] The utility model, through the arrangement of the rib plate and the side baffle, ensures that the test papers can be stacked reliably in the accommodating space, while effectively reducing the contact area between the test papers and the wall surface of the accommodating space, reducing the resistance of the test papers falling due to their own weight, so that the stacked test papers can fall stably and smoothly, ensuring the reliability and stability of the test paper distribution and pushing;
[0021] The utility model also has the following advantages:
[0022] The test papers stacked in the accommodating space are effectively ensured to be in a compact and stable stacking state in the front-to-back direction by the upper vertical bars combined with the rear plate. When the test papers fall to the horizontal bars, the protrusions that are slightly indented forward relative to the vertical bars limit and guide the test papers from the front, and a small space gap is reserved in the front-to-back direction for the test papers that are about to be separated and pushed, thereby effectively ensuring that the moving seat applies force to the test papers from the rear and separates and pushes them smoothly.
[0023] By embedding a block with higher hardness on the movable seat, the block applies force to the test paper to push the material, effectively reducing the wear of the force-applying parts. When necessary, the block can be replaced conveniently and quickly, thereby improving the overall service life of the pushing mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.
[0035] like Figure 1 As shown, a test paper dividing and pushing mechanism of the present embodiment includes a working platform 1, a movable seat 3 is installed on the working platform 1 for movement back and forth, a support plate 2 is installed on the working platform 1 on both sides of the movable seat 3, and a side plate 5 is installed on the support plate 2. A front plate 8 is installed between the side plates 5 on both sides, and the front plate 8 is horizontally mounted above the movable seat 3. The rear parts of the side plates 5 on both sides are respectively installed with rear plates 4. The side plates 5, the front plate 8 and the rear plate 4 together constitute an accommodating space for stacking test papers 10; a plurality of ribs 7 are installed on the side of the front plate 8 facing the accommodating space, and a side baffle 6 is installed on the side of the side plate 5 facing the accommodating space, and the ribs 7 and the side baffle 6 are in contact with the test paper 10.
[0036] In this embodiment, by setting the rib plate 7 and the side baffle 6, while ensuring the reliable stacking of the test paper 10 in the accommodating space, the contact area between the test paper 10 and the wall of the accommodating space is effectively reduced, and the resistance of the test paper 10 to falling due to its own weight is reduced, so that the stacked test paper 10 can fall stably and smoothly.
[0037] like Figure 2 As shown, the rib plate 7 includes vertical bars 71 installed on the side of the front plate 8 at intervals along the left-right direction, and a horizontal bar 72 is installed on the front plate 8 below the bottom end of the vertical bar 71.
[0038] The side of the transverse strip 72 extends toward the interior of the accommodating space to form a protrusion 73, and the side of the protrusion 73 is indented 0.1-0.5mm relative to the side of the vertical strip 71. Figure 3 shown.
[0039] The test papers 10 stacked in the accommodating space are effectively ensured to be in a compact and stable stacking state in the front-to-back direction by the upper vertical strips 71 combined with the rear plate 4. When the test papers 10 fall to the horizontal strips 72, the protrusions 73 slightly retracted forward relative to the vertical strips 71 limit and guide the test papers 10 from the front, and reserve a small space gap in the front-to-back direction for the test papers 10 to be separated and pushed, thereby effectively ensuring that the movable seat 3 applies force to the test papers 10 from the rear, and the separation and pushing are smooth.
[0040] The bottom end of the transverse strip 72 extends downward and protrudes from the bottom surface of the front plate 8. The spacing distance between the bottom surface of the transverse strip 72 and the top surface of the movable seat 3 is greater than the thickness of a single test paper 10 but less than the thickness of two test papers 10, thereby effectively ensuring that only the bottom test paper 10 is pushed forward by the movable seat 3, and the remaining test papers 10 will be blocked from moving forward.
[0041] like Figure 4 As shown, an embedding groove 32 is opened along the left and right direction on the movable seat 3 located behind the test paper 10, and an embedding block 11 is embedded in the embedding groove 32; the test paper 10 is supported on the supporting surface 30 of the movable seat 3 in front of the embedding block 11, and the height of the embedding block 11 is higher than the height of the supporting surface 30.
[0042] By embedding a block 11 with higher hardness on the movable seat 3, when pushing the material, the block 11 applies force to the test paper 10 to push the material, effectively reducing the wear of the force-applying part, and the block 11 can be replaced conveniently and quickly when necessary, thereby improving the overall service life of the material distribution and pushing mechanism.
[0043] like Figure 5As shown, the height difference between the embedment 11 and the supporting surface 30 is less than the thickness of a single test paper 10, thereby effectively ensuring that only the forward pushing force is applied to the bottom test paper 10; combined with the distance between the bottom end of the transverse strip 72 and the supporting surface 30 of the top surface of the movable seat 3 is set to only allow one test paper 10 to pass through, the reliability of the material distribution of the stacked test papers 10 in the accommodating space is effectively achieved.
[0044] The material hardness of the insert 11 is greater than the material hardness of the movable seat 3, which effectively reduces the wear of the insert 11 as the production progresses, and improves and ensures the material distribution and pushing effect and efficiency.
[0045] The movable seat 3 is provided with a plurality of long slots 31 arranged at intervals from the front edge to the rear. The long slots 31 divide the embedding slot 32 into multiple sections arranged at intervals on the left and right. The embedding blocks 11 of corresponding sizes are arranged in the single section embedding slot 32 .
[0046] In this embodiment, the arrangement of the long slot 31 forms a structural avoidance with the subsequent material receiving and supporting mechanism, which facilitates the material receiving and supporting mechanism to receive materials from the long slot 31 of the movable seat 3 in combination with the upward movement.
[0047] The support surface 30 is provided with a plurality of adsorption holes 33 , which are connected to an external air source. When separating and pushing materials, the adsorption holes 33 adsorb the bottom test paper 10 , thereby further ensuring the smoothness and accuracy of the separation and pushing operations.
[0048] A groove 81 is formed downwardly on the top edge of the front plate 8 to facilitate rapid and reliable loading of the stacked test strips 10 into the accommodating space.
[0049] In this embodiment, a movable guide assembly 9, such as a guide rail-slider assembly, can be installed on the work platform 1. This, combined with an external linear drive power source, applies force to the movable base 3 in the forward and backward movement direction, allowing the movable base 3 to move smoothly and accurately in a linear manner relative to the work platform 1, guided by the movable guide assembly 9. The linear drive power source can be a standard product that outputs linear power, such as a cylinder, or a power assembly consisting of a motor and a lead screw, or other power mechanism capable of achieving forward and backward movement of the movable base 3.
[0050] The usage of this utility model is:
[0051] The stacked test papers 10 are manually loaded and placed in the accommodating space. Under the action of their own gravity and the adsorption of the adsorption holes 33 on the bottom test paper 10, the bottom test paper 10 is supported on the supporting surface 30 of the movable base 3; the movable base 3 is pushed forward by an external linear driving force, so that the front side of the embedded block 11 on the movable base 3 applies force forward to the bottom test paper 10, so that the bottom test paper 10 moves forward with the movable base 3, thereby realizing the distribution and pushing of the test paper 10.
[0052] The utility model effectively reduces the contact area between the test paper and the wall surface of the accommodating space, reduces the resistance of the test paper to falling due to its own weight, enables the stacked test papers to fall stably and smoothly, and ensures the reliability and stability of the test paper distribution and pushing.
[0053] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0054] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
