[0002] Currently, when pH test paper is used for testing, a tape-type three-axis solution is usually adopted to move the test paper. However, in the related technology, the three-axis solution is large in size and is not conducive to use in scenarios with limited space. Utility Model Content

[0003] The utility model aims to at least solve the technical problem of excessively large system volume in the prior art or related art.

[0004] In view of this, an embodiment of the present utility model provides a test paper transmission system.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a test paper transmission system, including: a first gear shaft; a second gear shaft, the first gear shaft is meshed with the second gear shaft; a third gear shaft, the first gear shaft is meshed with the third gear shaft; a test paper roll, including a stacked test paper and a coating, part of the test paper roll is wound on the first gear shaft; a first wheel and a second wheel, the test paper and the coating of part of the test paper roll are separated, the separated test paper is wound around the first wheel and then wound around the second gear shaft, and the separated coating is wound around the second wheel and then wound around the third gear shaft.

[0006] A test paper transmission system provided in the utility model includes three gear shafts and two wheels for guiding, namely, a first gear shaft, a second gear shaft, a third gear shaft, a first wheel and a second wheel, wherein the test paper roll for pH detection is arranged on the first gear shaft, and the first gear shaft is meshed with the second gear shaft and the third gear shaft at the same time, and is located in the center of the system, and can transmit power from the driving wheel, so that the second gear shaft and the third gear shaft rotate together, and the second gear shaft and the third gear shaft are both driven shafts, and the first gear shaft is used to receive unused test paper rolls, and the second gear shaft is used to receive the test paper in the used test paper rolls, that is, the test paper after separation is received by the first wheel. The third gear shaft is meshed with the first gear shaft, and receives the separated coating through the second wheel, that is, the coating in the used test paper roll is received.

[0007] Among them, the test paper roll mainly includes test paper used for detection. The specific detection function is to detect the pH value of the liquid. A layer of coating is also provided on the surface of the test paper to reduce the possibility of the test paper failing due to environmental influences in the initial state.

[0008] The test paper roll is initially wound around the first gear shaft and is gradually transferred to other shafts as it is used.

[0009] The first wheel and the second wheel are used to guide the separation test paper and the coating respectively, so that the two enter the second gear shaft and the third gear shaft respectively.

[0010] It can be understood that the first wheel and the second wheel are located on the transmission path between the test paper roll and the second gear shaft and the third gear shaft.

[0011] The first round is close to the test paper roll, and the second round is close to the lamination path after separation.

[0012] It can be understood that, through the meshing relationship, the linear speeds of the first gear shaft, the second gear shaft and the third gear shaft are the same, which can effectively reduce the effect of relaxation caused by stress concentration due to chain drive or belt drive and improve transmission efficiency.

[0013] It can be understood that any one of the first gear shaft, the second gear shaft, the third gear shaft, the first wheel and the second wheel can be used as a driving source.

[0014] It should be emphasized that in this solution, the gear shaft used to place the test paper roll is directly meshed with the gear shaft for collecting the coating and detecting the test paper, which greatly reduces the volume of the entire test paper transmission system. At the same time, due to the use of gear meshing, the entire system can rotate both forward and reverse, reducing the waste of test paper during use.

[0015] In a specific embodiment, the first gear shaft rotates to gradually release the unused test paper roll, and the test paper roll passes through the first wheel and the second wheel to separate the test paper and the film, wherein the first wheel guides the test paper into the second gear shaft, and the second wheel guides the film into the third gear shaft. The second gear shaft stores the used test paper, and the third gear shaft stores the separated film.

[0016] The gear meshing ensures that the rotation speeds of the three axes are coordinated.

[0017] Among them, the second wheel can be used as a driving wheel to control the operating speed and direction of the entire system.

[0018] In some technical solutions, optionally, the first gear shaft includes: a first gear and a first shaft roller that are coaxially arranged; wherein a portion of the test paper is wound on the first shaft roller.

[0019] In this technical solution, the first gear shaft includes a first gear and a first roller, wherein the first gear is used to mesh with other gear shafts, transmit power and move synchronously. The tooth shape of the first gear includes but is not limited to a straight tooth or a helical tooth design to ensure smooth transmission. The first roller is used to store and release unused test paper rolls. By setting the first roller coaxially with the first gear, the overall occupied space is reduced, and direct transmission reduces intermediate links, ensuring precise synchronization of gear rotation and test paper release, and significantly improving synchronization.

[0020] The materials of the first gear and the first shaft roller can be the same or different. For example, the material of the first gear is wear-resistant metal, such as hardened steel or stainless steel, and the material of the first shaft roller is a light but strong material, such as aluminum alloy or reinforced plastic.

[0021] Among them, the unused test paper roll is directly wound on the first shaft roller to facilitate the rapid replacement of the new test paper roll. The first gear is engaged with other gear shafts to receive or transmit power. The rotation of the gear directly drives the shaft roller to rotate, thereby realizing the precise release of the test paper.

[0022] In some technical solutions, optionally, the second gear shaft includes: a second gear and a second shaft roller that are coaxially arranged, and the first gear is meshed with the second gear; wherein the separated test paper is wound around the second shaft roller.

[0023] In this technical solution, the second gear shaft includes a second gear and a second shaft roller, the second gear meshes with the first gear, receives power and moves synchronously, and the tooth shape of the second gear matches the tooth shape of the first gear, thereby ensuring precise meshing and smooth transmission.

[0024] The second shaft roller is used to receive the separated test paper, and to receive and release the part of the test paper in the test paper roll that has been used. By arranging the second shaft roller coaxially with the second gear, the overall occupied space is reduced, and direct transmission is adopted to reduce the intermediate links, thereby ensuring the precise synchronization between the gear rotation and the test paper release, and significantly improving the synchronization.

[0025] The materials of the second gear and the second shaft roller can be the same or different. For example, the material of the second gear is wear-resistant metal, such as hardened steel or stainless steel, and the material of the second shaft roller is a light but strong material, such as aluminum alloy or reinforced plastic.

[0026] In some technical solutions, optionally, the second gear is coupled to the second shaft roller via a one-way clutch, and the test paper transmission system further includes: a first auxiliary motor, which is transmission-connected to the second shaft roller, and the first auxiliary motor is used to drive the second shaft roller to rotate.

[0027] In this technical solution, a one-way clutch is provided between the second gear and the second shaft roller, and on this basis, a first auxiliary motor is provided for driving the second shaft roller to rotate. Specifically, the second gear is meshed with the first gear and participates in the main transmission system, and the second gear is coaxial with the second shaft roller and connected through a one-way clutch. Under the action of the one-way clutch located between the second gear and the second shaft roller, the second shaft roller is allowed to rotate independently of the second gear in one direction, so that when the test paper is loose, the first auxiliary motor can provide additional pulling force to play a tightening role and improve the storage effect of the test paper.

[0028] Under normal circumstances, the second shaft roller rotates following the second gear through the one-way clutch. When it is detected that the test paper becomes loose, the first auxiliary motor is started, and the auxiliary motor provides additional rotational force to help tighten the loose test paper.

[0029] It can be understood that the one-way clutch allows the second shaft roller to rotate faster than the gear system when needed (such as tightening the test paper), while preventing the power of the auxiliary motor from being transmitted back to the main transmission system, protecting the gears and the main drive source.

[0030] Furthermore, a tension sensor may be provided to monitor the tightness of the test paper in real time, and then, when the test paper is detected to be loose, the first auxiliary motor is triggered to operate.

[0031] Among them, the first auxiliary motor serves as a supplement and intervenes only when needed to ensure that the test paper always maintains appropriate tension.

[0032] In some technical solutions, optionally, the third gear shaft includes: a third gear and a third shaft roller that are coaxially arranged, and the first gear is meshed with the third gear; wherein the separated coating is wound around the third shaft roller.

[0033] In this technical solution, the third gear shaft includes a third gear and a third shaft roller, the third gear meshes with the first gear, receives power and moves synchronously, and the tooth shape of the third gear matches the tooth shape of the first gear, thereby ensuring precise meshing and smooth transmission.

[0034] The third shaft roller is used to receive the separated coating, and to receive and release the coated portion of the used test paper roll. By arranging the third shaft roller coaxially with the third gear, the overall occupied space is reduced, and direct transmission is adopted to reduce intermediate links, thereby ensuring precise synchronization between gear rotation and test paper release, and significantly improving synchronization.

[0035] The materials of the third gear and the third shaft roller can be the same or different. For example, the material of the third gear is wear-resistant metal, such as hardened steel or stainless steel, and the material of the third shaft roller is a light but strong material, such as aluminum alloy or reinforced plastic.

[0036] In some technical solutions, optionally, the third gear is coupled to the third shaft roller via a one-way clutch, and the test paper transmission system further includes: a second auxiliary motor, which is transmission-connected to the third shaft roller, and the second auxiliary motor is used to drive the third shaft roller to rotate.

[0037] In this technical solution, a one-way clutch is provided between the third gear and the third shaft roller, and on this basis, a second auxiliary motor is provided for driving the third shaft roller to rotate. Specifically, the third gear is meshed with the second gear, participating in the main transmission system, and the third gear is coaxial with the third shaft roller, connected by a one-way clutch, and under the action of the one-way clutch located between the third gear and the third shaft roller, the third shaft roller is allowed to rotate independently of the third gear in one direction, so that when the film is detected to be loose, the second auxiliary motor can provide additional pulling force to play a tightening role and improve the storage effect of the film.

[0038] Among them, under normal circumstances, the third shaft roller rotates following the third gear through the one-way clutch. When it is detected that the detection film becomes loose, the second auxiliary motor is started, and the auxiliary motor provides additional rotational force to help tighten the loose film.

[0039] It can be understood that the one-way clutch allows the third shaft roller to rotate faster than the gear system when needed (such as tightening the film), while preventing the power of the auxiliary motor from being transmitted back to the main transmission system, protecting the gears and the main drive source.

[0040] Furthermore, a tension sensor may be provided to monitor the tightness of the coating in real time, and then, when loosening of the coating is detected, the second auxiliary motor is triggered to operate.

[0041] The second auxiliary motor acts as a supplement and intervenes only when needed to ensure that the coating always maintains appropriate tension.

[0042] In some technical solutions, optionally, it includes: a first housing, in which a first gear shaft, a second gear shaft, a third gear shaft and a second wheel are arranged; and a second housing, in which a first wheel is arranged.

[0043] In this technical solution, two additional boxes are set up, namely the first box and the second box, wherein the first box is provided with a first gear shaft, a second gear shaft, a third gear shaft and a second wheel, which serve as the main transmission and storage containers, and the second box is provided with a first wheel, which can provide a guide space for the storage of used test strips, that is, the test strips will be separated before being moved out of the first box, and the separated test strips will be guided by the first wheel in the second box and finally returned to the first box, and the user or equipment can perform a drop detection operation on the test strips between the first box and the second box.

[0044] Furthermore, the first box body may be designed with a maintenance port or a detachable panel to facilitate the maintenance and replacement of internal components, and may also be equipped with a cooling or dehumidification system to ensure a stable internal environment.

[0045] By distributing the functions into two boxes, a more compact overall design can be achieved. The modularity of the system is demonstrated by adopting a split-box design, which not only improves the overall maintainability and flexibility, but also improves the performance and reliability of the system.

[0046] In some technical solutions, optionally, it further includes: a sample adding device, which is arranged between the first box body and the second box body, and the sample adding device is used to add the sample liquid to the test paper.

[0047] In this technical solution, an automatic sample adding device for adding sample liquid is added. The sample adding device is arranged between the first box and the second box, that is, between the second box for guiding the test paper and the first box for separation and storage. The sample adding device can be used to accurately add the sample liquid to the test paper. The test paper roll is separated in the first box, and the separated test paper is transferred from the first box to the second box. During the transfer process, the sample adding device can be controlled to accurately add the sample liquid to the test paper. The changes of the test paper can be observed between the first box and the second box, or in the second box, so as to make a judgment and realize the detection.

[0048] It can be understood that the sample adding device may have a micro syringe or a microfluidic pump to achieve precise liquid distribution, and may also have a positioning mechanism to ensure that the sample is accurately added to a specific position of the test paper.

[0049] Among them, the sample adding speed of the sample adding equipment needs to match the transmission speed of the test paper roll to ensure the continuity of the process.

[0050] The introduction of the sample adding device significantly improves the functionality and performance of the entire test strip transmission system during testing. It not only automates sample addition, but also optimizes the entire workflow by placing it between the first and second boxes.

[0051] In some technical solutions, optionally, it includes: a driving member, which is transmission-connected to the first wheel.

[0052] In this technical solution, by using the first wheel as the driving wheel and connecting the additional driving member to the first wheel, the rotation of the first wheel will drive the first gear shaft to rotate, and then through the meshing of the first gear shaft with the second gear shaft, and the meshing of the first gear shaft with the third gear shaft, the second gear shaft and the third gear shaft can respectively store the test paper and the coating.

[0053] Furthermore, the driving member starts, driving the first wheel to rotate. Under the action of the first wheel, the first gear shaft is driven to rotate. At this time, the test paper roll on the first gear shaft keeps moving. Under the action of the second wheel, the coating will be separated from the test paper. The separated test paper continues to move toward the sample adding device. After passing through the sample adding device, the test paper enters the first box body, and finally returns to the second gear shaft of the second box body to complete recycling.

[0054] In some technical solutions, optionally, it includes: a driving member, which is transmission-connected to the first gear shaft; wherein the second wheel is a tensioning wheel.

[0055] In this technical solution, the first gear shaft serves as a driving wheel to drive the test paper roll located thereon to rotate. Since the test paper roll is arranged on the first gear shaft serving as the driving wheel, the second gear shaft and the third gear shaft meshing therewith will be directly driven to rotate during the rotation process, thereby realizing the separation of the test paper roll and the transmission of the test paper.

[0056] It should be added that the second wheel used for guiding the test paper can be used as a tensioning wheel, thereby effectively reducing the possibility of the test paper being too loose due to the speed difference generated by the second wheel when the first gear shaft rotates. This can better control the tension of the test paper and help improve the stability and reliability of the separation and storage process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0064] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present invention, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0065] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0066] Refer to the following Figures 1 to 5 Some embodiments according to the present invention are described.

[0067] like Figure 1 and Figure 5 As shown, the present application provides a test paper transmission system 100, including three gear shafts and two wheels for guiding, namely a first gear shaft 102, a second gear shaft 104, a third gear shaft 106, a first wheel 110 and a second wheel 112, wherein a test paper roll 108 for pH detection is arranged on the first gear shaft 102, and the first gear shaft 102 is meshed with the second gear shaft 104 and the third gear shaft 106 at the same time, which is located in the center of the system and can transmit power from the driving wheel, so that the second gear shaft 104 and the third gear shaft 106 rotate together, and the second gear shaft 104 and the third gear shaft 106 are both driven shafts, the first gear shaft 102 is used to store unused test paper rolls 108, and the second gear shaft 104 is used to store test paper 1082 in the used test paper rolls 108, that is, the separated test paper 1082 is received by the first wheel 110. The third gear shaft 106 is meshed with the first gear shaft 102 , and receives the separated coating film 1084 through the second wheel 112 , that is, stores the coating film 1084 in the used test paper roll 108 .

[0068] Among them, the test paper roll 108 mainly includes a test paper 1082 for detection, and its specific detection function is to detect the pH value of the liquid. A layer of coating 1084 is also provided on the surface of the test paper 1082, so as to reduce the possibility of failure of the test paper 1082 due to environmental influences in the initial state.

[0069] The test paper roll 108 is initially wound around the first gear shaft 102 and is gradually transferred to other shafts during use.

[0070] The first wheel 110 and the second wheel 112 are used to guide the separation test paper 1082 and the coating 1084 respectively, so that the two enter the second gear shaft 104 and the third gear shaft 106 respectively.

[0071] It can be understood that the first wheel 110 and the second wheel 112 are located on the transmission path between the test paper roll 108 and the second gear shaft 104 and the third gear shaft 106 .

[0072] The first wheel 110 is close to the test paper roll 108 , and the second wheel 112 is close to the path of the separated coating 1084 .

[0073] It can be understood that, through the meshing relationship, the linear speeds of the first gear shaft 102, the second gear shaft 104 and the third gear shaft 106 are the same, which can effectively reduce the effect of relaxation caused by stress concentration due to chain drive or belt drive and improve transmission efficiency.

[0074] It can be understood that any one of the first gear shaft 102 , the second gear shaft 104 , the third gear shaft 106 , the first wheel 110 , and the second wheel 112 can be used as a driving source.

[0075] It should be emphasized that in the present solution, the gear shaft for placing the test paper roll 108 is directly meshed with the gear shafts for collecting the coating 1084 and detecting the test paper 1082, which greatly reduces the volume of the entire test paper transmission system 100. At the same time, due to the use of gear meshing, the entire system can rotate both forward and reverse, reducing the waste of test paper during use.

[0076] In a specific embodiment, the first gear shaft 102 rotates to gradually release the unused test paper roll 108, and the test paper roll 108 passes through the first wheel 110 and the second wheel 112 to separate the test paper 1082 and the coating 1084. Specifically, the first gear shaft 102 rotates clockwise, and the test paper roll 108 moves along the Figure 5 The first wheel 110 guides the test paper 1082 to enter the second gear shaft 104, and the second wheel 112 guides the coating 1084 to enter the third gear shaft 106. The second gear shaft 104 receives the used test paper 1082, and the third gear shaft 106 receives the separated coating 1084.

[0077] The gear meshing ensures that the rotation speeds of the three axes are coordinated.

[0078] The second wheel 112 can be used as a driving wheel to control the running speed and direction of the entire system.

[0079] In some embodiments, optionally, the first gear shaft 102 includes a first gear 1022 and a first shaft roller 1024, wherein the first gear 1022 is used to mesh with other gear shafts, transmit power and move synchronously. The tooth shape of the first gear 1022 includes but is not limited to a straight tooth or a helical tooth design to ensure smooth transmission. The first shaft roller 1024 is used to store and release unused test paper rolls 108. By setting the first shaft roller 1024 coaxially with the first gear, the overall occupied space is reduced, and direct transmission is performed, reducing intermediate links, ensuring accurate synchronization of gear rotation and test paper release, and significantly improving synchronization.

[0080] The materials of the first gear 1022 and the first shaft roller 1024 can be the same or different. For example, the material of the first gear 1022 is wear-resistant metal, such as hardened steel or stainless steel, and the material of the first shaft roller 1024 is a lightweight but strong material, such as aluminum alloy or reinforced plastic.

[0081] Among them, the unused test paper roll 108 is directly wound on the first shaft roller 1024 to facilitate the rapid replacement of the new test paper roll 108. The first gear 1022 is engaged with other gear shafts to receive or transmit power. The rotation of the gear directly drives the shaft roller to rotate, thereby achieving accurate release of the test paper.

[0082] In some embodiments, the second gear shaft 104 optionally includes a second gear 1042 and a second shaft roller 1044, the second gear 1042 meshes with the first gear, receives power and moves synchronously. The tooth shape of the second gear 1042 matches the tooth shape of the first gear, thereby ensuring precise meshing and smooth transmission.

[0083] The second shaft roller 1044 is used to receive the separated test paper 1082, and to receive and release the portion of the test paper 1082 in the used test paper roll 108. By arranging the second shaft roller 1044 and the second gear 1042 coaxially, the overall occupied space is reduced, and direct transmission is used to reduce intermediate links, thereby ensuring the precise synchronization of gear rotation and test paper release, and significantly improving synchronization.

[0084] The materials of the second gear 1042 and the second shaft roller 1044 can be the same or different. For example, the material of the second gear 1042 is wear-resistant metal, such as hardened steel or stainless steel, and the material of the second shaft roller 1044 is a lightweight but strong material, such as aluminum alloy or reinforced plastic.

[0085] In some embodiments, optionally, Figure 2 As shown, a one-way clutch 118 is provided between the second gear 1042 and the second shaft roller 1044, and on this basis, a first auxiliary motor 114 is provided for driving the second shaft roller 1044 to rotate. Specifically, the second gear 1042 is meshed with the first gear, participating in the main transmission system, and the second gear 1042 is coaxial with the second shaft roller 1044, connected by the one-way clutch 118, and under the action of the one-way clutch 118 located between the second gear 1042 and the second shaft roller 1044, the second shaft roller 1044 is allowed to rotate independently of the second gear 1042 in one direction, so that when the test paper 1082 is loose, the first auxiliary motor 114 can provide additional pulling force to play a tightening role, thereby improving the storage effect of the test paper 1082.

[0086] In which, under normal circumstances, the second shaft roller 1044 rotates following the second gear 1042 through the one-way clutch 118. When it is detected that the test paper 1082 becomes loose, the first auxiliary motor 114 is started, and the auxiliary motor provides additional rotational force to help tighten the loose test paper 1082.

[0087] It can be understood that the one-way clutch 118 allows the second shaft roller 1044 to rotate faster than the gear system when needed (such as tightening the test paper), while preventing the power of the auxiliary motor from being transmitted back to the main transmission system, thereby protecting the gears and the main drive source.

[0088] Furthermore, a tension sensor may be provided to monitor the tightness of the test paper 1082 in real time, and then, when the test paper is detected to be loose, the first auxiliary motor 114 is triggered to operate.

[0089] The first auxiliary motor 114 serves as a supplement and intervenes only when needed to ensure that the test paper always maintains appropriate tension.

[0090] In some embodiments, the third gear shaft 106 optionally includes a third gear 1062 and a third shaft roller 1064, and the third gear 1062 meshes with the first gear, receives power and moves synchronously. The tooth shape of the third gear 1062 matches the tooth shape of the first gear, thereby ensuring precise meshing and smooth transmission.

[0091] The third shaft roller 1064 is used to receive the separated coating 1084, and to receive and release the portion of the coating 1084 in the used test paper roll 108. By arranging the third shaft roller 1064 and the third gear 1062 coaxially, the overall occupied space is reduced, and direct transmission is used to reduce intermediate links, thereby ensuring the precise synchronization of gear rotation and test paper release, and significantly improving synchronization.

[0092] The materials of the third gear 1062 and the third shaft roller 1064 can be the same or different. For example, the material of the third gear 1062 is wear-resistant metal, such as hardened steel or stainless steel, and the material of the third shaft roller 1064 is a lightweight but strong material, such as aluminum alloy or reinforced plastic.

[0093] In some embodiments, optionally, Figure 2 and Figure 3 As shown, a one-way clutch 118 is provided between the third gear 1062 and the third shaft roller 1064, and on this basis, a second auxiliary motor 116 is provided for driving the third shaft roller 1064 to rotate. Specifically, the third gear 1062 is meshed with the second gear 1042, participating in the main transmission system, and the third gear 1062 is coaxial with the third shaft roller 1064, connected by the one-way clutch 118, and under the action of the one-way clutch 118 located between the third gear 1062 and the third shaft roller 1064, the third shaft roller 1064 is allowed to rotate independently of the third gear 1062 in one direction, so that when the detection film 1084 is loose, the second auxiliary motor 116 can provide additional pulling force to play a tightening role, thereby improving the storage effect of the coating 1084.

[0094] In which, under normal circumstances, the third shaft roller 1064 rotates following the third gear 1062 through the one-way clutch 118 , and when it is detected that the detection film 1084 becomes loose, the second auxiliary motor 116 is started, and the auxiliary motor provides additional rotational force to help tighten the loose film 1084 .

[0095] It can be understood that the one-way clutch 118 allows the third shaft roller 1064 to rotate faster than the gear system when needed (such as tightening the coating 1084), while preventing the power of the auxiliary motor from being transmitted back to the main transmission system, protecting the gears and the main drive source.

[0096] Furthermore, a tension sensor may be provided to monitor the tightness of the coating 1084 in real time, and then, when it is detected that the coating 1084 is loose, the second auxiliary motor 116 is triggered to operate.

[0097] The second auxiliary motor 116 serves as a supplement and intervenes only when needed to ensure that the coating 1084 always maintains appropriate tension.

[0098] In some embodiments, optionally, Figure 4As shown, two additional boxes are provided, namely a first box 120 and a second box 122, wherein the first box 120 is provided with a first gear shaft 102, a second gear shaft 104, a third gear shaft 106 and a second wheel 112, which serve as the main transmission and storage containers, and the second box 122 is provided with a first wheel 110, which can provide a guiding space for the storage of the used test paper 1082, that is, the test paper roll 108 will be separated before being moved out of the first box 120, and the separated test paper 1082 will be guided by the first wheel 110 in the second box 122, and finally return to the first box 120, and the user or the device can perform a drop detection operation on the test paper 1082 between the first box 120 and the second box 122.

[0099] Furthermore, the first box body 120 may be designed with a maintenance port or a detachable panel to facilitate maintenance and replacement of internal components, and may also be equipped with a cooling or dehumidification system to ensure a stable internal environment.

[0100] By distributing the functions into two boxes, a more compact overall design can be achieved. The modularity of the system is demonstrated by adopting a split-box design, which not only improves the overall maintainability and flexibility, but also improves the performance and reliability of the system.

[0101] In some embodiments, optionally, Figure 3 and Figure 4 As shown, a sample adding device 124 for automatically adding sample liquid is added, and the sample adding device 124 is arranged between the first box 120 and the second box 122, that is, between the second box 122 for guiding the test paper 1082 and the first box 120 for separating and storing. By using the sample adding device 124, the sample liquid can be accurately added to the test paper 1082, and the test paper roll 108 is separated in the first box 120. The separated test paper 1082 is transferred from the first box 120 to the second box 122. During the transfer process, the sample adding device 124 can be controlled to accurately add the sample liquid to the test paper 1082, and the changes of the test paper 1082 can be observed between the first box 120 and the second box 122, or in the second box 122, so as to make a judgment and realize the detection.

[0102] It can be understood that the sample adding device 124 may have a micro-syringe or a microfluidic pump to achieve precise liquid distribution, and may also have a positioning mechanism to ensure that the sample is accurately added to a specific position of the test paper.

[0103] The sample adding speed of the sample adding device 124 needs to match the conveying speed of the test paper roll 108 to ensure the continuity of the process.

[0104] The introduction of the sample adding device 124 significantly improves the function and performance of the entire test strip transmission system 100 during testing. It not only realizes the automation of sample addition, but also optimizes the entire workflow by arranging it between the first box 120 and the second box 122.

[0105] In some embodiments, optionally, the first wheel 110 is used as a driving wheel, and the additional driving member 126 is connected to the first wheel 110. The rotation of the first wheel 110 will drive the first gear shaft 102 to rotate, and then through the meshing of the first gear shaft 102 with the second gear shaft 104, and the meshing of the first gear shaft 102 with the third gear shaft 106, the second gear shaft 104 and the third gear shaft 106 can respectively accommodate the test paper 1082 and the coating 1084.

[0106] Further, the driving member 126 is started, driving the first wheel 110 to rotate. Under the action of the first wheel 110, the first gear shaft 102 is driven to rotate. At this time, the test paper roll 108 on the first gear shaft 102 is constantly moving. Under the action of the second wheel 112, the coating 1084 will be separated from the test paper 1082. The separated test paper 1082 continues to move toward the sample adding device 124. After passing through the sample adding device 124, the test paper 1082 enters the first box body 120, and finally returns to the second gear shaft 104 of the second box body 122 to complete recycling.

[0107] In some embodiments, optionally, the first gear shaft 102 serves as a driving wheel to drive the test paper roll 108 located thereon to rotate. Since the test paper roll 108 is provided on the first gear shaft 102 serving as the driving wheel, the second gear shaft 104 and the third gear shaft 106 meshing therewith are directly driven to rotate during the rotation process, thereby achieving the separation of the test paper roll 108 and the transmission of the test paper 1082.

[0108] It should be added that the second wheel 112 used to guide the test paper 1082 can be used as a tensioning wheel, thereby effectively reducing the possibility that the test paper 1082 is too loose due to the speed difference generated by the second wheel 112 when the first gear shaft 102 rotates, and can better control the tension of the test paper 1082, which helps to improve the stability and reliability of the separation and storage process.

[0109] In a specific embodiment, when the motor transmission shaft (i.e., the first wheel 110) rotates clockwise, the unused test paper shaft (i.e., the first gear shaft 102) rotates clockwise under the action of the test paper (i.e., the test paper roll 108), driving the film tearing roll (i.e., the third gear shaft 106) and the used test paper shaft (i.e., the second gear shaft 104) to rotate counterclockwise. At this time, the linear speeds of the four shafts are consistent, achieving the transmission of the test paper (test paper roll 108) and the storage of the used test paper (i.e., the test paper 1082) and the film 1084. The same applies to the reverse direction of rotation.
