Description

Technical Field

[0001] The utility model relates to the technical field of test strip production equipment, in particular to a test strip rolling cutting mechanism which is convenient for assembly and maintenance. Background Technique

[0002] Test strips are widely used and diverse in types, such as immunological test strips, electrochemical test strips, dry chemical test strips, etc.

[0003] Since test strips are generally slender, for the convenience of test strip processing, large long test strips are usually first made, and then the large long test strips are cut. After being cut into test strips of a set specification size, they are collected.

[0004] The cutting of test strips is usually realized by two sets of rotating cutter groups arranged side by side. A single set of rotating cutter group is composed of a plurality of blade discs stacked in series. When installing the rotating cutter group, it is necessary to make the blade discs in the two sets of rotating cutter groups stagger each other to form a shearing structure. In the prior art, since the rotating cutter group contains a plurality of blade discs, the assembly operation of the two sets of rotating cutter groups is quite inconvenient.

[0005] Moreover, with the progress of rolling cutting, the blade disc is a consumable part. It is necessary to periodically adjust the distance between the two sets of rotating cutters to ensure the rolling cutting action, and even replace the blade discs on the rotating cutters. When adjusting and maintaining the existing rotating cutters, the operation is very troublesome, time-consuming and laborious, and the efficiency is low. Summary of the Utility Model

[0006] To solve the above problems, the present application provides a test strip rolling cutting mechanism which is reasonable in structure and convenient for assembly and maintenance, so as to realize the quick staggered tool setting of the corresponding blade discs in the cutter assembly one and the cutter assembly two, which is convenient for actual operation, improves efficiency and ensures the effect.

[0007] The technical solution adopted by the utility model is as follows:

[0008] A test strip rolling cutting mechanism which is convenient for assembly and maintenance includes side plates arranged at intervals, and a cutter assembly one and a cutter assembly two are rotatably installed together between the side plates; both the cutter assembly one and the cutter assembly two include a rotating shaft rotatably installed on both side plates, and a plurality of blade discs are sleeved on the rotating shaft. The blade discs in the cutter assembly one and the blade discs in the cutter assembly two are staggered to form a shearing structure; a limiting member one is installed on the rotating shaft of the cutter assembly one, and a limiting member two is installed on the rotating shaft of the cutter assembly two. The limiting member one and the limiting member two are assembled to form mutual positioning and limiting of the two rotating shafts in the axial direction.

[0009] As a further improvement of the above technical solution:

[0010] The first limiting member is a disc fixedly sleeved on the rotating shaft of the first cutter assembly. An annular groove is circumferentially arranged on the second limiting member, and the edge of the disc extends into the annular groove.

[0011] The thickness of the disc is adapted to the width of the annular groove.

[0012] The second limiting member includes two discs arranged at intervals, and the interval between the two discs forms the annular groove.

[0013] The diameter of the disc is larger than the diameter of the blade disc.

[0014] On the rotating shaft, a step is formed by the shaft shoulder to limit the installation positions of the first limiting member and the second limiting member.

[0015] Each blade disc is equidistantly installed on the rotating shaft, and a rubber pad is arranged at the interval between adjacent blade discs.

[0016] The stacked blade discs and rubber pads are axially limited and fixed on the rotating shaft by a locking nut.

[0017] At both ends of the rotating shaft in the first cutter assembly, supports are rotatably sleeved. A long groove for the sliding fit of the supports is opened on the side plate. At the end of the support located at the opening of the long groove, a top plate is installed, and a long bolt is locked through the top plate towards the support.

[0018] It further includes a power driving mechanism. In the power driving mechanism, the driving gear is driven to rotate by an external power mechanism; on the same side ends of the rotating shafts of the first cutter assembly and the second cutter assembly, an intermediate gear and a driven gear are respectively sleeved, and the driving gear, the intermediate gear, and the driven gear are sequentially meshed and transmitted pairwise.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] By respectively installing the first limiting member and the second limiting member on the rotating shafts of the two cutter assemblies, during the installation and maintenance process, through the mutual fit of the first limiting member and the second limiting member, the quick staggered fit and tool alignment of the corresponding blade discs in the first cutter assembly and the second cutter assembly can be realized, which is convenient for actual operation, improves efficiency, and ensures the effect;

[0021] The utility model further has the following advantages:

[0022] The fit setting between the first limiting member and the second limiting member not only facilitates the mutual fit and tool alignment operation of the first cutter assembly and the second cutter assembly, but also can play a guiding role in the rotation of the two cutter assemblies during the rotary cutting process, effectively ensuring and maintaining the axial relative position between the first cutter assembly and the second cutter assembly during use, and providing guarantee for the rotary cutting accuracy;

[0023] The cutter assembly is slidably mounted in the long groove of the side plate via the support. As the rotary cutting progresses and the cutting edge of the blade disc wears, the distance between the first cutter assembly and the second cutter assembly can be conveniently and quickly adjusted by sliding the support in the long groove, so as to quickly compensate for the wear of the cutting edge of the blade disc and ensure the smooth progress of rotary cutting.

[0024] In the power drive mechanism, the first cutter assembly and the second cutter assembly are driven to rotate synchronously through external meshing gear transmission to realize rotary cutting. Moreover, the intermediate gear in the first cutter assembly and the driven gear in the second cutter assembly are driven to rotate by the driving gear driven by the external power mechanism. The entire rotary cutting mechanism can be quickly connected or disengaged relative to the power source, which effectively facilitates the quick change operation of the entire rotary cutting mechanism without involving the installation and disassembly of the external power mechanism.

[0031] The following combines with the drawings to illustrate the detailed embodiment of the present utility model.

[0032] As Figure 1 and Figure 2 shown, a test strip rotary cutting mechanism convenient for assembly and maintenance in this embodiment includes side plates 11 arranged at intervals. Between the side plates 11, a first cutter assembly 5 and a second cutter assembly 6 are rotatably installed together; both the first cutter assembly 5 and the second cutter assembly 6 include rotating shafts rotatably installed on both side plates 11, and a plurality of blade discs are sleeved on the rotating shafts. The blade discs in the first cutter assembly 5 and the blade discs in the second cutter assembly 6 are arranged alternately to form a shearing structure; a first limiting member 3 is installed on the rotating shaft of the first cutter assembly 5, and a second limiting member 4 is installed on the rotating shaft of the second cutter assembly 6. The first limiting member 3 and the second limiting member 4 are assembled to form mutual positioning and limiting of the two rotating shafts in the axial direction.

[0033] In this embodiment, by respectively installing the first limiting member 3 and the second limiting member 4 on the rotating shafts of the two groups of cutting tool assemblies, during the installation and maintenance process, through the mutual fitting of the first limiting member 3 and the second limiting member 4, the quick staggered fitting and tool alignment of the corresponding blade discs in the first cutting tool assembly 5 and the second cutting tool assembly 6 can be realized, which is convenient for actual operation.

[0034] The first limiting member 3 is a disc fixedly sleeved on the rotating shaft of the first cutting tool assembly 5. The second limiting member 4 is provided with a circumferential groove along the circumferential direction, and the edge of the disc extends into the circumferential groove.

[0035] In actual operation, by fitting the disc of the first limiting member 3 into the circumferential groove of the second limiting member 4, the quick staggered corresponding fitting and tool alignment of the blade discs in the first cutting tool assembly 5 and the second cutting tool assembly 6 are realized.

[0036] In this embodiment, the fitting setting between the first limiting member 3 and the second limiting member 4 not only facilitates the mutual fitting and tool alignment operation of the first cutting tool assembly 5 and the second cutting tool assembly 6, but also can play a guiding role in the rotation of the two groups of cutting tool assemblies during the hobbling use process, effectively ensuring and maintaining the axial relative position between the first cutting tool assembly 5 and the second cutting tool assembly 6 during use, and providing a guarantee for the hobbling accuracy.

[0037] The thickness of the disc is adapted to the width of the circumferential groove, effectively ensuring the reliability and stability of its axial limit and fitting.

[0038] The second limiting member 4 includes two discs arranged at intervals, and the interval between the two discs forms a circumferential groove.

[0039] In this embodiment, the first limiting member 3 and the second limiting member 4 can both be composed of similar or even the same discs, thereby effectively reducing the types of parts and facilitating actual processing, assembly and maintenance.

[0040] In this embodiment, the interval between the two discs in the second limiting member 4 can be realized and maintained by gaskets, shaft cylinders, etc. with smaller diameters sleeved on the rotating shaft.

[0041] The diameter dimension of the disc is larger than the diameter dimension of the blade disc, thereby effectively ensuring the fitting depth between the first limiting member 3 and the second limiting member 4 and effectively ensuring its axial limiting effect.

[0042] On the rotating shaft, steps are formed by shaft shoulders to limit the installation positions of the first limiting member 3 and the second limiting member 4, which helps to ensure the accuracy of the axial relative position of the first cutting tool assembly 5 and the second cutting tool assembly 6.

[0043] Each blade disc is installed on the rotating shaft at equal intervals, and a rubber pad is arranged at the interval between adjacent blade discs.

[0044] The stacked blade discs and rubber pads are axially limited and fixed on the rotating shaft by a locking nut 7, effectively ensuring the stacking reliability and stability of the blade discs and rubber pads on the rotating shaft.

[0045] In actual operation, the stacked blade discs and rubber pads on the rotating shaft can also be axially limited by other structural forms, as long as the structural stability of the stacked blade discs and rubber pads can be ensured and the reliability of the position of the stacked structure on the rotating shaft can be guaranteed.

[0046] At both ends of the rotating shaft in the first cutter assembly 5, there are rotatably sleeved supports 8. A long groove 111 for the sliding fit of the support 8 is provided on the side plate 11. At the end of the support 8 located at the opening of the long groove 111, there is a top plate 9 installed, and a long bolt 91 is locked through the top plate 9 towards the support 8.

[0047] In this embodiment, the first cutter assembly 5 is slidably fitted in the long groove 111 of the side plate 11 via the support 8. As the rotary cutting progresses and the cutting edge of the blade disc wears, the distance between the first cutter assembly 5 and the second cutter assembly 6 can be conveniently and quickly adjusted by the sliding of the support 8 in the long groove 111, so as to quickly compensate for the wear of the cutting edge of the blade disc and ensure the smooth progress of the rotary cutting.

[0048] In actual operation, by rotating the long bolt 91 relative to the top plate 9, the support 8 can be driven to move relative to the side plate 11 along the long groove 111, so as to adjust the distance between the first cutter assembly 5 and the second cutter assembly 6.

[0049] In this embodiment, a guiding groove 81 for fitting with the side wall of the long groove 111 can also be provided on the outer wall surface of the support 8, effectively ensuring the stability and reliability of the up-and-down movement of the support 8 relative to the side plate 11.

[0050] It also includes a power driving mechanism 2. In the power driving mechanism 2, the driving gear 21 is driven to rotate by an external power mechanism; on the same side ends of the rotating shafts in the first cutter assembly 5 and the second cutter assembly 6, an intermediate gear 22 and a driven gear 23 are respectively sleeved, and the driving gear 21, the intermediate gear 22, and the driven gear 23 are sequentially meshed and transmitted pairwise.

[0051] In this embodiment, in the power driving mechanism 2, the first cutter assembly 5 and the second cutter assembly 6 are driven to rotate synchronously through external meshing gear transmission to achieve rotary cutting, and the driving gear 21 driven by the external power mechanism drives the intermediate gear 22 in the first cutter assembly 5 and the driven gear 23 in the second cutter assembly 6 to rotate. The entire rotary cutting mechanism can be quickly connected or disengaged relative to the power source, effectively facilitating the quick change operation of the entire rotary cutting mechanism without involving the installation and disassembly actions of the external power mechanism.

[0052] In this embodiment, the first cutter assembly 5 and the second cutter assembly 6 are vertically assembled between the two side plates 11. Of course, in actual operation, according to actual requirements, the first cutter assembly 5 and the second cutter assembly 6 can also be arranged in the same horizontal plane and arranged in a left-right side-by-side structural form. Through the opposite rotation of the first cutter assembly 5 and the second cutter assembly 6 and the staggered arrangement of the blade discs, the rolling cutting of the test strip is realized.

[0053] In this embodiment, the two side plates 11 can be jointly installed on the base 1 to form a relatively fixed integral structure, effectively ensuring the structural reliability of the rolling cutting mechanism.

[0054] The utility model realizes the quick staggered tool setting of the corresponding blade discs in the first cutter assembly and the second cutter assembly, can quickly adjust their distance, is convenient for actual operation and maintenance, improves efficiency and ensures the effect.

[0055] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.
