Description

Technical Field

[0001] The utility model relates to the field of pH test paper detection, in particular to a test paper transmission system. Background Art

[0002] At present, when pH test paper is used for detection, 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 during use, the test paper is easily disturbed by impurities or water vapor in the air, affecting the detection accuracy. Utility Model Content

[0003] The utility model aims to at least solve the technical problem of low detection accuracy existing in the prior art or related technology.

[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 wheel and a second wheel; a test paper roll, including a stacked test paper and a coating, and part of the test paper roll is wound on the first wheel; a sealing sleeve, located between the first wheel and the second wheel, the test paper and the coating of part of the test paper roll are separated, and the separated test paper passes through the sealing sleeve and extends to the second wheel; a plurality of guide wheels, which are arranged on one side of the test paper, and the separated coating is guided by the guide wheel and extends to the second wheel.

[0006] A test paper transmission system provided in the utility model includes a first wheel and a second wheel for conveying test paper rolls. The test paper rolls can be separated and stored by utilizing a dual-axis structure, thereby greatly reducing the space occupied by the system. On this basis, the test paper and the coating can be automatically separated and conveyed, so that the test paper can be effectively exposed and tested during the detection process, while maintaining the sealing and continuity of the system.

[0007] Specifically, the first wheel is used to store and release part of the test paper roll. In the initial state, the test paper and the coating are stacked together, and part of the test paper roll is wound on the first wheel. The second wheel is used to receive and collect the separated test paper and coating to ensure the continuity of the transmission process. The first wheel is used to ensure that the test paper roll can be smoothly unfolded and enter the transmission system, and the second wheel is used to collect the separated test paper and coating to maintain the orderliness of the transmission system. The test paper roll contains stacked test paper and coating. On this basis, a sealing sleeve is set between the first wheel and the second wheel to ensure that the test paper is not affected by the external environment during the transmission process after separation, and prevent the test paper from being infiltrated or oxidized after separation from the coating, which causes it to fail, maintain sealing, and ensure the accuracy of the test results.

[0008] It should be added that there is a space inside the sealing sleeve, and the test paper is collected by the second round after passing through this space.

[0009] Among them, in order to guide the separated coating and complete the storage, a guide wheel can be set on one side of the test paper so that the coating can be smoothly extended to the second wheel, ensuring the stability of the coating during transmission, preventing its deviation, and maintaining the smooth operation of the transmission system.

[0010] Furthermore, the first wheel and the second wheel are connected by a transmission belt or other transmission device of the test paper roll and the film to achieve automatic transmission. By arranging a sealing sleeve between the first wheel and the second wheel, it is ensured that during the transmission of the test paper roll, especially after the film is torn off, the exposed test paper can always be in a sealed environment.

[0011] The number and position of the guide wheels are relatively flexible, as long as it can be ensured that the coating can be guided to the second wheel on the transmission path after separation.

[0012] It should be emphasized that compared with the existing three-axis technology, this solution reduces one storage axis. The two-axis transmission takes into account the separation and storage of the test paper and the coating, while also reducing the possibility of loosening. On this basis, a sealing sleeve is added, so that the interference of impurities on the test results is reduced while occupying a smaller space, thereby improving the detection accuracy of the test paper.

[0013] In some technical solutions, optionally, it also includes: an inlet, which is arranged at one end of the sealing sleeve facing the first wheel, and the test paper enters the sealing sleeve through the inlet; an outlet, which is arranged at one end of the sealing sleeve facing the second wheel, and the test paper moves out of the sealing sleeve through the outlet.

[0014] In this technical solution, an inlet and an outlet are respectively provided at both ends of the sealing sleeve to facilitate the movement of the test paper during the transmission process. Specifically, the inlet is provided at one end of the sealing sleeve facing the first wheel, providing a channel for the test paper to enter the sealing sleeve. Under the action of the inlet, the direction and angle of the test paper entering the sealing sleeve can be controlled, on the one hand, ensuring that the test paper can be smoothly separated from the test paper roll and enter the sealing sleeve, and on the other hand, reducing the wrinkles or damage that may occur to the test paper during the entry process. The outlet is provided at one end of the sealing sleeve facing the second wheel, providing a channel for the test paper to leave the sealing sleeve, which is mainly used to control the direction and angle of the test paper leaving the sealing sleeve, on the one hand, ensuring that the test paper can smoothly leave the sealing sleeve and move to the second wheel, and on the other hand, maintaining the sealing inside the sealing sleeve and reducing the interference of the external environment.

[0015] It can be understood that by arranging the inlet close to the first round, the test paper on the test paper roll can directly enter the sealing sleeve, thereby minimizing the time the test paper is exposed to the external environment.

[0016] Similarly, by arranging the outlet toward the second wheel, the test paper can be directly moved to the second wheel, ensuring that the test paper can be received by the second wheel as soon as possible after leaving the sealing sleeve, reducing possible interference in the intermediate process.

[0017] It can be understood that the inlet and the outlet are respectively located at the two ends of the sealing sleeve, forming a complete sealed channel, so that the test paper is in a controlled environment during the entire transmission process, reducing the impact of the external environment on the test results.

[0018] In some technical solutions, optionally, it includes: a sealing member, which is arranged at the entrance, and the test paper passes through the sealing member and enters the sealing sleeve.

[0019] In this technical solution, by setting a seal at the entrance, the sealing performance and protection effect of the test paper transmission system are further enhanced. It can be understood that the seal provides a sealed entry channel for the test paper, preventing outside air and pollutants from entering the sealing sleeve, keeping the internal environment clean, enhancing the sealing of the sealing sleeve, and ensuring that the test paper is not contaminated by the outside world during transmission.

[0020] The sealing member may be a rubber sealing ring, an adaptive sealing member or an antistatic sealing member.

[0021] In some technical solutions, optionally, it includes: a sample adding port, which is arranged on the sleeve wall of the sealing sleeve, and in the gravity direction, the sample adding port is arranged above the test paper.

[0022] In this technical solution, by adding a sample adding port, the test strip transmission system can conveniently add samples while maintaining the system's airtightness and ease of operation. Specifically, the sample adding port provides a convenient entrance for adding samples or reagents to the test strip, ensuring that the test strip's transmission is not affected or damaged when adding samples.

[0023] It can be understood that, under the action of the sample adding port, the operator can conveniently add samples or reagents to the test paper being transmitted, thereby improving the efficiency of the operation. In addition, the sample adding port is arranged above the test paper in the gravity direction, which is convenient for the natural dripping and uniform distribution of the liquid sample, thereby ensuring the uniformity and accuracy of the detection process.

[0024] It should be added that the sample adding port is arranged on the sleeve wall of the sealing sleeve to ensure that the overall sealing performance of the sealing sleeve is not damaged during the sample adding process. This design can prevent impurities in the external environment from entering the system through the sample adding port.

[0025] The design of the sample adding port enables operators to easily add samples without disassembling or opening the system, simplifying the operation process. In addition, the sealing design of the sample adding port ensures that the sealing of the system will not be affected when adding samples, preventing external contaminants from entering.

[0026] Furthermore, the sample adding port may be equipped with a controllable opening and closing device to ensure that it remains sealed when sample adding is not required.

[0027] In some technical solutions, optionally, it further includes: a sample adding device, which is arranged opposite to the sample adding port, and the sample adding device is used to add the sample liquid to the test paper.

[0028] In this technical solution, an automatic sample adding device for adding sample liquid is added. The sample adding device is located between the first round and the second round, and the sample adding device is arranged opposite to the sample adding port. By using the sample adding device, the sample liquid can be accurately passed through the sample adding port and added to the test paper. After the test paper rolls are separated, the separated test paper is transferred to the second round. During the transmission process, the sample adding device can be controlled to accurately add the sample liquid to the test paper, and then the changes of the test paper can be observed in the sealing sleeve, so as to make a judgment and realize the detection.

[0029] 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.

[0030] 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.

[0031] In some technical solutions, optionally, it includes: a detection port, which is arranged on the sleeve wall of the sealing sleeve, and the detection port is provided with a visible component; wherein the detection port is arranged on the side of the sample addition port facing the second wheel.

[0032] In this technical solution, the detection port provides a window for observing the reaction results of the test paper. By setting a visual component at the detection port, the operator or the detection equipment is allowed to read the result without opening the sealing sleeve, thereby realizing real-time monitoring of the detection process and improving the detection efficiency. While maintaining the sealing of the system, it allows result observation and data collection.

[0033] The detection port is located on the side of the sample addition port facing the second round, ensuring that the sample has enough reaction time after addition, which is conducive to observing the entire process from sample addition to completion of reaction. The detection port is integrated on the wall of the sealing sleeve, maintaining the overall sealing of the system, allowing observation and detection without damaging the seal.

[0034] It should also be added that the detection port faces the second round and is located at the rear section of the test paper transmission path, which is conducive to observing the final result of the reaction.

[0035] It can be understood that the entire system can not only realize the automatic transmission of test strips and the convenient addition of samples, but also perform real-time observation and result reading while maintaining sealing, thereby improving the efficiency, accuracy and reliability of the detection process.

[0036] In some technical solutions, optionally, it includes: a lamination device, which is arranged between the first wheel and the second wheel, and the lamination device is arranged corresponding to the position where the test paper roll extends out of the first wheel.

[0037] In this technical solution, a laminating device is provided between the first round and the second round, and the laminating device can perform laminating processing on the test paper roll released from the first round, thereby ensuring that the test paper and the coating remain in close contact before entering into subsequent processing.

[0038] Under the action of the pressing equipment, the flatness of the test paper roll can be effectively improved, wrinkles and bubbles can be reduced, and preparations can be made for the subsequent separation process to ensure smoother separation.

[0039] Specifically, the specific structure of the pressing device may include one or more pairs of symmetrically arranged rollers for uniformly applying pressure.

[0040] The lamination equipment is located between the first and second wheels to ensure that the test paper roll is properly handled when it is changed from the storage state to the detection state. On this basis, by setting the lamination equipment corresponding to the position where the test paper roll extends out of the first wheel, it is ensured that the entire width of the test paper roll can be evenly laminated, thereby improving the effectiveness and consistency of the lamination process.

[0041] In some technical solutions, optionally, it includes: a driving member, which is transmission-connected to the second wheel.

[0042] In this technical solution, the second wheel is used as the driving wheel, and the additional driving member is connected to the second wheel. The rotation of the second wheel will drive the first wheel to rotate together, thereby realizing the separation of the test paper rolls and the storage of the test paper and the coating.

[0043] Furthermore, the driving member starts, driving the second wheel to rotate, and under the action of the second wheel, the first wheel is driven to rotate. At this time, the test paper roll on the first wheel keeps moving, and under the action of the second wheel, the coating will be separated from the test paper, and the separated test paper continues to move toward the sealing sleeve, and the test paper enters the second wheel after passing through the sealing sleeve, and the coating enters the second wheel under the action of multiple guide wheels, and the test paper and the sealing sleeve are recovered under the action of the second wheel.

[0044] In some technical solutions, optionally, at least one of the multiple guide wheels is a tensioning wheel.

[0045] In this technical solution, by using the tensioning wheel as at least one of the multiple guide wheels, the tension of the coating can be effectively adjusted and maintained, compensating for the tension changes that may occur during the operation of the system, improving the stability and smoothness of the coating transmission, reducing the wrinkles or relaxation that may occur in the coating during the transmission process, and facilitating the accurate separation of the coating and the test paper.

[0046] The tension wheel can be set near the separation point of the laminating film and the test paper or in the long-distance transmission section. The tension wheel directly contacts and acts on the laminating film to control its tension and flatness.

[0047] In some technical solutions, optionally, the second wheel specifically includes: a wheel body, on which the test paper is wound; two baffles, which are arranged on both axial sides of the wheel body, and the test paper is located between the two baffles.

[0048] In this technical solution, the second wheel includes a wheel body and two baffles located on both sides of the wheel body in an axial direction, wherein the wheel body provides a surface for collecting and storing the test strips, ensuring that the test strips can be collected smoothly and orderly.

[0049] The surface of the wheel body may be specially treated to enhance the friction with the test paper.

[0050] The baffle is mainly used to limit the lateral movement of the test paper, ensure that the test paper remains aligned during the collection process, and prevent the test paper from shifting or wrinkling during the collection process. The baffle is located on both sides of the axial direction of the wheel body to form a limited space. This setting ensures that the test paper always remains within the predetermined width range during the collection process.

[0051] In some technical solutions, optionally, it also includes: after the coating is guided by a plurality of guide wheels, it is attached to the detection test paper on the second wheel.

[0052] In this technical solution, after being guided by multiple guide wheels, the coating is fitted with the test paper on the second wheel. After the test is completed, the coating is re-combined with the test paper to protect the test paper that has completed the test and prevent contamination or damage.

[0053] It can be understood that the coating is re-bonded to the test paper in the second round to form a complete packaging process. Of course, the bonding process needs to be precisely controlled to ensure that it will not affect the completed test results.

[0054] In this solution, not only the automatic transmission of test strips, sample addition and testing are realized, but also the function of automatic packaging and protection is provided after the test is completed, which improves the practicality of the system and the reliability of the samples, so that the entire testing process is under high control and protection from beginning to end.

[0055] In some technical solutions, optionally, it also includes: a film collecting roller, which is arranged on one axial side of the wheel body, and the axis of the film collecting roller is colinear with the axis of the wheel body; wherein the coating film is guided by multiple guide wheels and then wound on the film collecting roller.

[0056] In this technical solution, the film collecting roller is arranged on one axial side of the wheel body, and the axis of the film collecting roller is colinear with the axis of the wheel body, so as to collect the separated film. At the same time, under the action of the film collecting roller, the tension and flatness of the film are maintained, so as to facilitate the recovery or reuse of the film.

[0057] In this solution, the coated film is finally wound onto the film collecting roller after passing through a plurality of guide wheels. The coated film is recovered separately under the action of the film collecting roller and separated from the used test paper, thereby forming a complete coating film recovery path.

DETAILED DESCRIPTION

[0065] 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.

[0066] 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.

[0067] Refer to the following Figures 1 to 5 Some embodiments according to the present invention are described.

[0068] like Figures 1 to 3 As shown, the present application provides a test paper transmission system 100, including a first wheel 102 and a second wheel 104 for conveying a test paper roll 108. The test paper roll 108 can be separated and stored by utilizing a dual-axis structure, thereby greatly reducing the space occupied by the system. On this basis, the automatic separation and transmission of the test paper 1082 and the coating 1084 can be achieved, so that the test paper 1082 can be effectively exposed and tested during the detection process, while maintaining the sealing and continuity of the system.

[0069] Specifically, the first wheel 102 is used to store and release part of the test paper roll 108. In the initial state, the test paper and the coating 1084 are stacked together, and part of the test paper roll 108 is wound on the first wheel 102. The second wheel 104 is used to receive and collect the separated test paper 1082 and the coating 1084 to ensure the continuity of the transmission process. The first wheel 102 is used to ensure that the test paper roll 108 can be smoothly unfolded and enter the transmission system, and the second wheel 104 is used to collect the separated test paper 1082 and the coating 1084 to maintain the orderliness of the transmission system. The test paper roll 108 includes the test paper 1082 and the coating 1084 arranged in a stacked manner. On this basis, by arranging a sealing sleeve 106 between the first wheel 102 and the second wheel 104, it is ensured that the test paper 1082 is not affected by the external environment during the transmission process after separation, and prevents the test paper 1082 from being infiltrated or oxidized after being separated from the coating 1084, causing it to fail, maintain sealing, and ensure the accuracy of the test results.

[0070] It should be added that there is a space inside the sealing sleeve 106 , and the test paper 1082 is received by the second wheel 104 after passing through the space.

[0071] In order to guide the separated coating 1084 and complete the storage, a guide wheel 110 can be set on one side of the test paper 1082 so that the coating 1084 can be smoothly extended to the second wheel 104, ensuring the stability of the coating 1084 during the transmission process, preventing it from shifting, and maintaining the smooth operation of the transmission system.

[0072] Furthermore, the first wheel 102 and the second wheel 104 are connected by a transmission belt or other transmission device of the test paper roll 108 and the coating 1084 to achieve automatic transmission. By setting the sealing sleeve 106 between the first wheel 102 and the second wheel 104, it is ensured that during the transmission of the test paper roll 108, especially after the film is torn off, the exposed test paper 1082 can always be in a sealed environment.

[0073] The number and position of the guide wheels 110 are relatively flexible, as long as it can ensure that the coating 1084 can be guided to the second wheel 104 on the transmission path after separation.

[0074] It should be emphasized that compared with the existing three-axis technology, this solution reduces one storage axis. The two-axis transmission takes into account the separation and storage of the test paper 1082 and the coating 1084, while also reducing the possibility of loosening. On this basis, a sealing sleeve 106 is added, so that the interference of impurities on the test results is reduced while occupying a smaller space, thereby improving the detection accuracy of the test paper 1082.

[0075] In some embodiments, optionally, Figure 2 and Figure 3 As shown, an inlet 1062 and an outlet 1064 are respectively provided at both ends of the sealing sleeve 106 to facilitate the movement of the test paper 1082 during the conveying process. Specifically, the inlet 1062 is provided at one end of the sealing sleeve 106 facing the first wheel 102, providing a channel for the test paper 1082 to enter the sealing sleeve 106. Under the action of the inlet 1062, the direction and angle of the test paper 1082 entering the sealing sleeve 106 can be controlled, on the one hand, ensuring that the test paper 1082 can be smoothly separated from the test paper roll 108 and enter the sealing sleeve 106, and on the other hand, reducing the wrinkles or damage that may occur to the test paper 1082 during the entry process. The outlet 1064 is disposed at one end of the sealing sleeve 106 facing the second wheel 104, providing a channel for the test paper 1082 to leave the sealing sleeve 106, and is mainly used to control the direction and angle of the test paper 1082 leaving the sealing sleeve 106, on the one hand to ensure that the test paper 1082 can smoothly leave the sealing sleeve 106 and move toward the second wheel 104, and on the other hand to maintain the sealing inside the sealing sleeve 106 and reduce interference from the external environment.

[0076] It can be understood that by arranging the inlet 1062 close to the first wheel 102, the test paper 1082 on the test paper roll 108 can directly enter the sealing sleeve 106, thereby minimizing the time for the test paper 1082 to be exposed to the external environment.

[0077] Similarly, by arranging the outlet 1064 toward the second wheel 104, the test paper 1082 can be directly moved toward the second wheel 104, ensuring that the test paper 1082 can be received by the second wheel 104 as soon as possible after leaving the sealing sleeve 106, thereby reducing possible interference in the intermediate process.

[0078] It can be understood that the inlet 1062 and the outlet 1064 are respectively located at the two ends of the sealing sleeve 106, forming a complete sealed channel, so that the test paper 1082 is in a controlled environment during the entire transmission process, reducing the impact of the external environment on the test results.

[0079] In some embodiments, optionally, Figure 3 As shown, a seal 1066 is provided at the inlet 1062, which further enhances the sealing performance and protective effect of the test paper transmission system 100. It can be understood that the seal 1066 provides a sealed entry channel for the test paper 1082, prevents outside air and pollutants from entering the sealing sleeve 106, keeps the internal environment clean, enhances the sealing performance of the sealing sleeve 106, and ensures that the test paper 1082 is not contaminated by the outside world during the transmission process.

[0080] Specifically, the seal 1066 may be a rubber seal ring, an adaptive seal 1066 or an antistatic seal 1066 .

[0081] In some embodiments, optionally, Figure 3 As shown, adding a sample adding port 1068 enables the test paper transmission system 100 to conveniently add samples while maintaining the sealing and convenience of the system. Specifically, the sample adding port 1068 provides a convenient entrance 1062 for adding samples or reagents to the test paper 1082, ensuring that the transmission of the test paper 1082 will not be affected or the test paper 1082 will not be damaged when adding samples.

[0082] It can be understood that, under the action of the sample adding port 1068, the operator can conveniently add samples or reagents to the test paper 1082 being transmitted, thereby improving the efficiency of the operation. In addition, the sample adding port 1068 is arranged above the test paper 1082 in the gravity direction, which is convenient for the natural dripping and uniform distribution of the liquid sample, thereby ensuring the uniformity and accuracy of the detection process.

[0083] It should be added that the sample addition port 1068 is arranged on the sleeve wall of the sealing sleeve 106 to ensure that the overall sealing of the sealing sleeve 106 is not damaged during the sample addition process. This design can prevent impurities in the external environment from entering the system through the sample addition port 1068.

[0084] The design of the sample adding port 1068 enables the operator to conveniently add samples without disassembling or opening the system, thereby simplifying the operation process. In addition, the sealing design of the sample adding port 1068 ensures that the sealing of the system is not affected when adding samples, thereby preventing external contaminants from entering.

[0085] Furthermore, the sample adding port 1068 may be equipped with a controllable opening and closing device to ensure that it remains sealed when sample adding is not required.

[0086] In some embodiments, optionally, Figure 1 As shown, a sample adding device 124 for automatically adding sample liquid is added. The sample adding device 124 is located between the first wheel 102 and the second wheel 104, and the sample adding device 124 is arranged opposite to the sample adding port 1068. By using the sample adding device 124, the sample liquid can be accurately passed through the sample adding port 1068 and added to the test paper 1082. After the test paper roll 108 is separated, the separated test paper 1082 is transferred to the second wheel 104. During the transmission process, the sample adding device 124 can be controlled to accurately add the sample liquid to the test paper 1082, and then the changes of the test paper 1082 can be observed in the sealing sleeve 106, so as to make a judgment and realize the detection.

[0087] 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.

[0088] 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.

[0089] In some embodiments, optionally, Figure 3 As shown, the detection port 1070 provides a window for observing the reaction results of the test paper 1082. By providing a visual component 1072 at the detection port 1070, an operator or a detection device is allowed to read the result without opening the sealing sleeve 106, thereby realizing real-time monitoring of the detection process, improving the detection efficiency, and allowing result observation and data collection while maintaining the sealing of the system.

[0090] The detection port 1070 is located on the side of the sample addition port 1068 facing the second round, ensuring that the sample has sufficient reaction time after addition, which is conducive to observing the entire process from sample addition to reaction completion. The detection port 1070 is integrated on the wall of the sealing sleeve 106, maintaining the overall sealing of the system, allowing observation and detection without damaging the seal.

[0091] It should also be added that the detection port 1070 faces the second round and is located at the rear section of the transmission path of the test paper 1082, which is conducive to observing the final result of the reaction.

[0092] It can be understood that the entire system can not only realize the automatic transmission of the test paper 1082 and the convenient addition of samples, but also perform real-time observation and result reading while maintaining sealing, thereby improving the efficiency, accuracy and reliability of the detection process.

[0093] In some embodiments, optionally, Figure 1 and Figure 2 As shown, a laminating device 112 is provided between the first wheel 102 and the second wheel. The laminating device 112 can perform laminating processing on the test paper roll 108 released from the first wheel 102 to ensure that the test paper 1082 and the coating 1084 remain tightly fitted before entering the subsequent processing.

[0094] Under the action of the pressing device 112, the flatness of the test paper roll 108 can be effectively improved, wrinkles and bubbles can be reduced, and preparations can be made for the subsequent separation process to ensure smoother separation.

[0095] Specifically, the specific structure of the pressing device 112 may include one or more pairs of symmetrically arranged rollers for applying pressure evenly.

[0096] The laminating device 112 is located between the first wheel 102 and the second wheel 104 to ensure that the test paper roll 108 is properly handled when it is changed from the storage state to the detection state. On this basis, by setting the laminating device 112 corresponding to the position where the test paper roll 108 extends out of the first wheel 102, it is ensured that the entire width of the test paper roll 108 can be evenly laminated, thereby improving the effectiveness and consistency of the laminating process.

[0097] In some embodiments, optionally, Figure 2 As shown, the second wheel 104 is used as the driving wheel, and the additional driving member 126 is connected to the second wheel 104 in a transmission manner. The rotation of the second wheel 104 will drive the first wheel 102 to rotate together, thereby realizing the separation of the test paper roll 108 and the storage of the test paper 1082 and the coating 1084.

[0098] Further, the driving member 126 is started, driving the second wheel 104 to rotate. Under the action of the second wheel 104, the first wheel 102 is driven to rotate. At this time, the test paper roll 108 on the first wheel 102 is constantly moving. Under the action of the second wheel 104, the coating 1084 will be separated from the test paper 1082. The separated test paper 1082 continues to move toward the sealing sleeve 106. After passing through the sealing sleeve 106, the test paper 1082 enters the second wheel 104. The coating 1084 enters the second wheel 104 under the action of multiple guide wheels 110. Under the action of the second wheel 104, the test paper 1082 and the sealing sleeve 106 are recovered.

[0099] In some embodiments, optionally, at least one of the plurality of guide wheels 110 is a tensioning wheel.

[0100] In this embodiment, by using the tensioning wheel as at least one of the multiple guide wheels 110, the tension of the coating 1084 can be effectively adjusted and maintained, compensating for the tension changes that may occur during the operation of the system, improving the stability and smoothness of the transmission of the coating 1084, reducing the wrinkles or relaxation that may occur in the coating 1084 during the transmission process, and facilitating the accurate separation of the coating 1084 from the test paper 1082.

[0101] The tension wheel can be arranged near the separation point of the coating 1084 and the test paper 1082 or in the long-distance transmission section. The tension wheel directly contacts and acts on the coating 1084 to control its tension and flatness.

[0102] In some embodiments, optionally, Figure 4 As shown, the second wheel 104 includes a wheel body 1042 and two baffles 1044 located on both sides of the wheel body 1042 axially, wherein the wheel body 1042 provides a collection and storage surface for the test strips 1082 to ensure that the test strips 1082 can be collected smoothly and orderly.

[0103] The surface of the wheel body 1042 may be specially treated to enhance the friction with the test paper 1082 .

[0104] The baffle 1044 is mainly used to limit the lateral movement of the test paper 1082, ensuring that the test paper 1082 remains aligned during the collection process, and preventing the test paper 1082 from being offset or wrinkled during the collection process. The baffle 1044 is located on both sides of the axial direction of the wheel body 1042 to form a limited space. This arrangement ensures that the test paper 1082 always remains within a predetermined width range during the collection process.

[0105] In some embodiments, optionally, Figure 1 and Figure 2As shown, after being guided by a plurality of guide wheels 110, the coating 1084 is attached to the test paper 1082 on the second wheel 104. After the test is completed, the coating 1084 is re-combined with the test paper 1082 to protect the test paper that has completed the test and prevent contamination or damage.

[0106] It can be understood that the coating 1084 is re-bonded to the test paper 1082 on the second wheel 104 to form a complete packaging process. Of course, the bonding process needs to be precisely controlled to ensure that it will not affect the completed test results.

[0107] In this solution, not only the automatic transmission, sample addition and detection of the test paper 1082 are realized, but also the function of automatic packaging and protection is provided after the detection is completed, which improves the practicality of the system and the reliability of the samples, so that the entire detection process is under high control and protection from beginning to end.

[0108] In some embodiments, optionally, Figure 5 As shown, a newly added film collecting roller 1046 is specifically arranged on one axial side of the wheel body 1042, and the axis of the film collecting roller 1046 is colinear with the axis of the wheel body 1042, so as to collect the separated coating 1084. At the same time, under the action of the film collecting roller 1046, the tension and flatness of the coating 1084 are maintained, so as to facilitate the recovery or reuse of the coating 1084.

[0109] In this solution, the coating 1084 is finally wound onto the film collecting roller 1046 after passing through a plurality of guide wheels 110. The coating 1084 is recovered separately by the film collecting roller 1046 and separated from the used test paper 1082, thereby forming a complete recycling path for the coating 1084.
