[0003] The present application aims to at least solve the technical problem that the test paper is easy to loosen in the prior art or related art.

[0004] To solve the above problems, the present application provides a test paper transmission system, comprising: a first test paper wheel, a second test paper wheel and a film winding wheel, the second test paper wheel and the film winding wheel rotate independently; a test paper strip comprising test paper and a film body stacked; part of the test paper strip is wound on the first test paper wheel, the test paper of part of the test paper strip is wound on the second test paper wheel, and the film body of part of the test paper strip is wound on the film winding wheel; the second test paper wheel drives the first test paper wheel to rotate; a rotation damping assembly is arranged on the first test paper wheel, and the rotation damping assembly cooperates with the first test paper wheel to limit the minimum rotation driving force of the first test paper wheel.

[0005] According to the test paper transmission system provided by the present application, automatic transmission, separation and recovery of the test paper are realized, and the efficiency and accuracy of test paper detection are greatly improved. Specifically, the system comprises a first test paper wheel, a second test paper wheel and a film winding wheel, the first test paper wheel is used for storing and releasing unused test paper strips, ensuring the continuity of test paper supply and reducing the frequency of manual operation, and the first test paper wheel serves as the starting end of the system and directly contacts the test paper strip. The second test paper wheel is used for collecting test paper after detection, realizing orderly recovery of the test paper, and facilitating subsequent processing or disposal. It can be understood that the second test paper wheel directly contacts the test paper. The film winding wheel is used for collecting the film body peeled from the test paper, realizing separate recovery of the film body, and facilitating recycling or processing. The film winding wheel is located in the middle of the system and directly contacts the film body.

[0006] The test paper strip is composed of test paper and film body stacked, which provides test paper required for detection and protects the test paper from pollution. The test paper strip is connected with the three wheels at the same time, realizing transmission and separation.

[0007] The second test paper wheel and the film winding wheel are connected with the first test paper wheel through the test paper strip, drive the whole system to run, realize automatic transmission of the test paper, reduce the additional power source, and simplify the system structure.

[0008] It is emphasized that the rotating damping assembly is arranged on the first test paper wheel in the present application, which applies resistance to the first test paper wheel, slows down the rotating speed, ensures that the test paper belt is always in a tension state, prevents relaxation or wrinkling, and can also control the release speed of the test paper, which is synchronized with the detection process.

[0009] The first test paper wheel, the detection area, the second test paper wheel and the film winding wheel are arranged in sequence to realize linear transmission and processing of the test paper.

[0010] The rotating damping assembly sets a resistance, so that the force driving the first test paper wheel to rotate must be greater than the set resistance, and the test paper is always in a tension state, facilitating the pipetting and detection of the test paper in the measurement area. Further, the rotating damping assembly is arranged on the first test paper wheel, and in the process of winding the test paper belt by the second test paper wheel to drive the first test paper wheel to rotate and transmit the test paper belt, the resistance set by the rotating damping assembly must be overcome, so that the entire path of the test paper from the first test paper wheel to the test area and then to the second test paper wheel is always in a tension state, facilitating the pipetting and detection of the test paper in the measurement area. The test area is located on the test paper transmission system and can be used as a test paper placement platform. The detection area is used for placing the test paper, which is convenient for personnel detection.

[0011] In some technical solutions, the base is further provided with the rotating damping assembly; the rotating damping assembly comprises a damper, one end of the damper is connected to the base, the other end of the damper is connected to the first test paper wheel, and part of the damper rotates together with the first test paper wheel; and an idler shaft is arranged on the base, the idler shaft comprises an integrated first shaft and a second shaft, the first shaft and the second shaft have collinear shaft centers; the first test paper wheel is rotatably arranged on the first shaft; and the damper is arranged on the second shaft, and part of the damper rotates relative to the second shaft.

[0012] In this technical solution, the base is used to provide a stable support structure for the entire system, ensure the relative positions of the components are fixed, and improve the stability of the system. The rotating damping assembly is arranged on the base and fixed by the base, which ensures the stability and consistency of the stretching force.

[0013] One end of the damper is connected to the base, the other end of the damper is connected to the first test paper wheel, a controllable damping force is provided, the rotating speed of the first test paper wheel is adjusted, and then the accurate tension control of the test paper belt is realized, which prevents the test paper belt from relaxing suddenly or being stretched excessively. Of course, the damping force can be adjusted according to different types of test paper.

[0014] By synchronously rotating part of the damper with the first test paper wheel, the continuous action of the damping force is ensured, the stable tension is maintained in the entire test paper transmission process, the relative friction between the damper and the test paper wheel is reduced, and the service life is prolonged.

[0015] The idler shaft is arranged on the base and specifically includes a first shaft and a second shaft which are integrated and have the same axis, wherein the first test paper wheel is rotatably arranged on the first shaft to allow the first test paper wheel to rotate freely while keeping its position, and the damper is arranged on the second shaft, part of the damper rotates relative to the second shaft to realize part rotation of the damper while keeping its position fixed, allowing the damper to rotate with the first test paper wheel and keeping the continuous damping effect.

[0016] In some technical solutions, the anti-rotation plate is arranged on the base, a non-circular hole is formed in the anti-rotation plate, and the non-circular hole is matched with the second shaft; and the limiting member is arranged on the first shaft to axially limit the first test paper wheel.

[0017] In this technical solution, the anti-rotation plate is arranged on the base, and the non-circular hole is formed in the anti-rotation plate, which can effectively prevent the second shaft from rotating, ensure the fixed position of the idler shaft, prevent the whole from rotating, and also ensure the constant direction of the force of the damper, thereby improving the consistency of the damping effect.

[0018] In addition, the limiting member is arranged on the first shaft to axially limit the first test paper wheel, thereby preventing the first test paper wheel from moving in the axial direction and ensuring that the test paper strip keeps the correct alignment position during the conveying process.

[0019] Under the joint action of the anti-rotation plate, the non-circular hole and the second shaft, the position and movement of the idler shaft can be accurately controlled, a stable support point is provided, the force of the damper is always kept in the predetermined direction, unnecessary vibration and shaking in the system are reduced, and the operation stability and reliability of the whole system are improved.

[0020] The design of the anti-rotation plate and the non-circular hole can improve the stability of the idler shaft, and the limiting member can provide accurate positioning for the test paper strip. These improvements not only improve the operation accuracy and stability of the system, but also enhance its reliability and durability. At the same time, this design also considers the convenience of maintenance and adjustment, making the whole system more practical and efficient.

[0021] In some technical solutions, the diameter of the first shaft is greater than the diameter of the second shaft; the end face of the first shaft close to the second shaft is in abutment with the end face of the damper away from the base; the second shaft is provided with a clamping groove, and a clamping spring is arranged in the clamping groove.

[0022] In this technical solution, the diameter of the first shaft is greater than the diameter of the second shaft, so as to distinguish different functional areas, facilitate assembly and maintenance, on the one hand, enhance the strength of the first shaft to better support the first test paper wheel, and on the other hand, reduce the weight of the second shaft to reduce the burden of the damper. On this basis, the end face of the first shaft close to the second shaft is in abutment with the end face of the damper away from the base to limit the axial movement of the damper, ensure the correct positional relationship between the damper and the first test paper wheel, and guarantee the stability and consistency of the damping force.

[0023] In addition, by providing a clamping groove on the second shaft, a clamping spring is arranged in the clamping groove, the axial fixation of the damper or other components is realized, and axial sliding of the damper or other components on the second shaft is prevented.

[0024] In some technical solutions, optionally, a connecting plate is further included, one end of the connecting plate is fixedly connected with the damper, and the other end is provided with at least one connecting shaft; the first test paper wheel is provided with at least one connecting hole; and the connecting shaft is connected with the connecting hole in a matched mode.

[0025] In this technical solution, the connecting plate is arranged on the damper, and the first test paper wheel is connected with the connecting plate through the cooperation between the connecting hole and the shaft hole of the connecting shaft. Since one end of the connecting plate is fixedly connected with the damper, the connecting plate serves as a bridge between the damper and the first test paper wheel, and can effectively disperse and bear various forces and moments from the rotation of the first test paper wheel. The overall stability is improved, so that the damper can work more stably, and looseness or damage caused by vibration or impact is reduced.

[0026] In some technical solutions, optionally, a first motor is arranged on the second test paper wheel to drive the second test paper wheel to rotate; and a second motor is arranged on the film winding wheel to drive the film winding wheel to rotate.

[0027] In this technical solution, the first motor is arranged on the second test paper wheel, and is used to drive the second test paper wheel to rotate; the second motor is arranged on the film winding wheel, and is used to drive the film winding wheel to rotate; and the first motor and the second motor provide power sources for the entire device.

[0028] In some technical solutions, optionally, the first test paper wheel is arranged on the base, and includes a first test paper shaft for winding a test paper strip, and two first baffles arranged at two ends of the first test paper shaft respectively and used for axially limiting the test paper strip; the second test paper wheel is arranged on the base, and includes a second test paper shaft for winding a test paper; the second test paper wheel further includes two second baffles arranged at two ends of the second test paper shaft respectively and used for axially limiting the test paper; and the film winding wheel is arranged on the base, and includes a film winding shaft for winding a film body; the film winding wheel further includes two film baffles arranged at two ends of the film winding shaft respectively and used for axially limiting the film body.

[0029] In this technical solution, the first test paper wheel includes a first test paper shaft and two first baffles, and is arranged on the base, wherein the first test paper shaft is used for winding a test paper strip, and the two first baffles axially limit the test paper strip, so as to ensure that the test paper strip is wound on the shaft in an orderly and neat manner, prevent the test paper strip from being deviated or loosened in the axial direction, and improve the stability and consistency of the test paper strip releasing process.

[0030] Similarly, the second test paper wheel comprises a second test paper shaft for winding the test paper after detection and two second stop plates for axially limiting the test paper, orderly collecting the used test paper, facilitating subsequent processing, and preventing the test paper from being wrinkled or misaligned during recycling.

[0031] The film winding wheel comprises a film winding shaft for winding the film body peeled off from the test paper and two film stop plates for axially limiting the film body, realizing orderly recycling of the film body, facilitating subsequent processing or recycling, and preventing the film body from being wrinkled or misaligned during recycling.

[0032] It can be understood that the three wheels all comprise a central shaft and stop plates at both ends, realizing orderly transmission and recycling of the test paper tape, test paper and film body, improving the modularization degree of the system, and facilitating component replacement and upgrading.

[0033] The base provides a stable mounting platform for the three wheels, ensures the relative positions between components fixed, and improves the stability and accuracy of the entire system.

[0034] In some technical solutions, optionally, the system further comprises a sensor arranged on the base and in contact with part of the film body, the sensor being configured to determine tension information of the film body, wherein the tension information comprises a slack state of the film body or a taut state of the film body; and a controller electrically connected to the sensor and the second motor, the controller being configured to control the second motor to rotate or stop rotating according to the tension information of the film body, wherein when the sensor sends the tension information of the film body to the controller as the slack state, the controller controls the second motor to stop working, and when the sensor sends the tension information of the film body to the controller as the taut state, the controller controls the second motor to start working.

[0035] In this technical solution, the sensor is arranged on the base and in contact with part of the film body, detects the tension state of the film body, monitors the tension condition of the film body in real time, distinguishes whether the film body is in the slack state or the taut state, and provides real-time feedback of the state of the film body. The controller is electrically connected to the sensor and the second motor, receives and processes the tension information of the sensor, determines the working state of the second motor according to the state of the film body, and ensures that the film body always maintains appropriate tension. The specific control logic is as follows: in the slack state, the controller instructs the second motor to stop working, and in the taut state, the controller instructs the second motor to start working, which can realize dynamic adjustment of the tension of the film body, prevent the film body from being excessively taut or relaxed, ensure the smoothness and continuity of the recycling process of the film body, and reduce the risk of damage to the film body during recycling.

[0036] In some embodiments, a plurality of guide mechanisms are arranged on the base, and the guide mechanisms provide guidance and support for the test paper strip, the test paper, and the film body.

[0037] In the embodiments, the plurality of guide mechanisms are arranged on the base, and the guide mechanisms provide guidance and support for the test paper strip, the test paper, and the film body. The plurality of guide mechanisms respectively provide movement paths for the test paper strip, the test paper, and the film body, and reduce the frictional resistance of the test paper strip, the test paper, and the film body during movement, so that the test paper strip, the test paper, and the film body move more smoothly.

[0038] In some embodiments, the first test paper wheel, the second test paper wheel, and the film winding wheel are arranged on the same side of the base.

[0039] In the embodiments, the base can be understood as a plate structure, and the base includes two surfaces. The first test paper wheel, the second test paper wheel, and the film winding wheel are arranged on the same side of the base, i.e., the first test paper wheel, the second test paper wheel, and the film winding wheel are located on the same side of the base. The path of the test paper strip is relatively stable, and the test paper and the film body are more easily separated.

[0040] Further, the radial dimension of the film winding wheel is smaller than the radial dimension of the first test paper wheel and smaller than the radial dimension of the second test paper wheel.

[0041] In the embodiments, the radial dimension of the film winding wheel is smaller than the radial dimension of the first test paper wheel, and the radial dimension of the film winding wheel is smaller than the radial dimension of the second test paper wheel. The design meets the design features of the test paper strip, i.e., the thickness of the test paper is relatively large, and the thickness of the film body is relatively thin. The film winding wheel is designed to be small in size, which is more convenient for distinguishing the film winding wheel from the first test paper wheel and the second test paper wheel by volume and is beneficial for installation.

DETAILED DESCRIPTION

[0056] In order to enable a more complete understanding of the above-mentioned purposes, features and advantages of the embodiments of the present application, the embodiments of the present application are further described in detail below with reference to the accompanying drawings and specific embodiments. 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.

[0057] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the embodiments of the present application can 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.

[0058] Some embodiments of the present application are described below with reference to Figs. 1-12.

[0059] As shown in Figs. 1 and 2, the present application provides a test paper transmission system to realize automatic transmission, separation and recovery of test paper, and improve the efficiency and accuracy of test paper detection. Specifically, the system includes a first test paper wheel 110, a second test paper wheel 130 and a film winding wheel 140. The first test paper wheel 110 is used to store and release unused test paper strips 111 as shown in Fig. 11, ensuring the continuity of test paper supply and reducing the frequency of manual operation. The first test paper wheel 110 serves as the starting end of the system and is in direct contact with the test paper strips 111. The second test paper wheel 130 is used to collect test papers that have completed detection, realizing the orderly recovery of test papers and facilitating subsequent processing or disposal. It can be understood that the second test paper wheel 130 is in direct contact with the test papers 131. The film winding wheel 140 is used to collect the film bodies 141 peeled off from the test papers, realizing the separate recovery of the film bodies 141 and facilitating recycling or disposal. The film winding wheel 140 is located in the middle of the system and is in direct contact with the film bodies 141.

[0060] The test paper strips 111 are composed of test papers 131 and film bodies 141 stacked together, providing test papers required for detection and protecting the test papers from contamination. The test paper strips 111 are connected to the three wheels at the same time, realizing transmission and separation.

[0061] The second test paper wheel 130 and the film winding wheel 140 are connected to the first test paper wheel 110 through the test paper strips 111, driving the entire system to operate, realizing automatic transmission of test papers, reducing additional power sources and simplifying the system structure.

[0062] It is emphasized that a rotation damping assembly 120 is provided on the first test paper wheel 110 in the present scheme, which applies resistance to the first test paper wheel 110, ensuring that the test paper strips 111 are always in a tensioned state and preventing slackening or wrinkling.

[0063] Among them, the first test paper wheel 110, the second test paper wheel 130 and the film winding wheel 140 are arranged in sequence, and the detection area is arranged between the first test paper wheel 110 and the second test paper wheel 130, realizing linear transmission and processing of test papers.

[0064] Among them, the second test paper wheel 130 and the film winding wheel 140 are driven by respective stepping motors.

[0065] The rotation of the second test paper wheel 130 is directly driven by its own stepping motor. The rotation of the second test paper wheel 130 drives the test paper tape 111 to move, thereby driving the first test paper wheel 110 to rotate, both in the clockwise direction. The rotation of the film winding wheel 140 is directly driven by its own stepping motor. When the film body 141 is loosened from the tightened state, the triggering state of the sensor 200 will change. At this time, the stepping motor starts to drive the film winding wheel 140 to rotate, and the rotation speed is faster than that of the second test paper wheel 130. When the film body 141 changes from the loosened state to the tightened state, the triggering state of the sensor 200 (micro switch) changes again. At this time, the stepping motor stops rotating. This cycle is repeated to complete the action of tearing and covering the film.

[0066] It can be understood that the test paper tape 111 is wound on the first test paper wheel 110, and the test test paper 131 is wound on the second test paper wheel 130. The winding of the test test paper 131 on the second test paper wheel 130 can drive the first test paper wheel 110 to rotate, and the rotation direction of the first test paper wheel 110 is consistent with that of the second test paper wheel 130. Similarly, the film body 141 is wound on the film winding wheel 140, and the rotation direction of the first test paper wheel 110 is opposite to that of the film winding wheel 140.

[0067] In addition, when the second test paper wheel 130 winds the test test paper 131, the test test paper 131 drives the test paper tape 111 to move, and the test paper tape 111 drives the first test paper wheel 110 to rotate. During the winding of the film body 141 on the film winding wheel 140, the film body 141 can be separated from the test paper tape 111. Finally, the film body 141 is wound on the film winding wheel 140, and the test test paper 131 is wound on the second test paper wheel 130.

[0068] The rotation damping assembly 120 is arranged on the first test paper wheel 110, and the rotation damping assembly 120 sets the minimum rotation driving force of the first test paper wheel 110, so that the test test paper 131 is always in the tightened state. Because the rotation damping assembly 120 is arranged on the first test paper wheel 110, in the process of winding the test test paper 131 on the second test paper wheel 130 to drive the first test paper wheel 110 to rotate and convey the test paper tape 111, the resistance set by the rotation damping assembly 120 must be overcome, so that the test test paper 131 is always in the tightened state from the first test paper wheel 110 to the test area and then to the second test paper wheel 130. This facilitates the pipetting and detection of the test test paper 131 in the measurement area. The test area is located on the test paper transmission system and can be used as a test paper placement platform. The detection area is used to place the test test paper 131, which facilitates the detection of the color of the pipetted test test paper 131 by the camera above the test area.

[0069] It is necessary to supplement that one end of the rotation damping assembly 120 is connected to the first test paper wheel 110, and the other end is fixed to the base 10. It sets a resistance size, and it must be greater than the set resistance to drive the first test paper wheel 110 to rotate. Therefore, during the movement process, the test paper 131 is always subjected to tension, so that it is in a taut state. This facilitates the alignment of the pipetting position, and also effectively improves the identification effect of the camera above the detection area.

[0070] In some embodiments, as shown in FIGS. 1-3, the base 10 is used to provide a stable support structure for the entire system, ensure the relative position of each component is fixed, improve the stability of the system, and the rotation damping assembly 120 is arranged on the base 10 and fixed by the base 10. The base 10 provides support and fixation for the rotation damping assembly 120, ensuring the stability and consistency of the rotation damping force.

[0071] The rotation damping assembly 120 includes a damper 121, one end of which is connected to the base 10 and the other end is connected to the first test paper wheel 110. The damper 121 connects the base 10 and the first test paper wheel 110, providing support and fixation for the first test paper wheel 110. Part of the damper 121 rotates with the first test paper wheel 110. It can be understood that the damper 121 is divided into two parts, one part is fixed with the base 10, and the other part is fixed with the first test paper wheel 110. The relative rotation of the two parts of the damper 121 generates a frictional resistance. When the first test paper wheel 110 rotates, the resistance generated by the damper 121 acts on the first test paper wheel 110, and the resistance is ultimately transmitted to the test paper strip 111 to achieve the purpose of tightening the test paper 131.

[0072] One end of the damper 121 is connected to the base 10, and the other end is connected to the first test paper wheel 110, providing controllable damping force to prevent the test paper strip 111 from suddenly relaxing or overstretching. Of course, the damping force can be adjusted according to different types of test paper. By synchronously rotating the damper 121 part with the first test paper wheel 110, the continuous action of the damping force is ensured, and stable tension is maintained during the entire test paper conveying process, reducing the relative friction between the damper 121 and the test paper wheel, and prolonging the service life.

[0073] The damper 121 is a pair of relatively rotating turntables connected by screws, one end of which is fixed to the base 10 and the other end is fixed to the first test paper wheel 110. When the first test paper wheel 110 rotates, it drives the rotation. The idler shaft 122 is installed in the coaxial holes of the base 10, the damper 121 and the first test paper wheel 110, and its main purpose is to support the first test paper wheel 110.

[0074] It is necessary to emphasize that the size of the damping force generated by the damper 121 can be realized according to the locking force of the screw between the two relatively rotating turntables, that is, the size of the damping force is changed by adjusting the locking degree.

[0075] The rotation damping assembly 120 further comprises an idler shaft 122, which is arranged on the base 10 and the damper 121, and is supported and fixed by the base 10 and the damper 121. The idler shaft 122 comprises an integral first shaft 1221 and a second shaft 1222, and the first shaft 1221 and the second shaft 1222 have the same axis. The same axis of the first shaft 1221 and the second shaft 1222 ensures that the first test paper wheel 110 has the same axis with the damper 121. The first test paper wheel 110 is rotatably arranged on the first shaft 1221, and rotates relative to the first shaft 1221 and the second shaft 1222. The damper 121 is arranged on the second shaft 1222, and part of the damper 121 rotates relative to the second shaft 1222. It can be understood that the damper 121 is divided into two parts, one part is fixed with the base 10, and the other part is fixed with the first test paper wheel 110. The two parts of the damper 121 rotate relative to each other to generate resistance. The other part of the damper 121 fixed with the first test paper wheel 110 rotates relative to the second shaft 1222, so as to facilitate the resistance of the damper 121 acting on the first test paper wheel 110.

[0076] In some embodiments, as shown in FIGS. 2, 3 and 10, the base 10 is provided with an anti-rotation plate 118, and a non-circular hole 1181 is formed in the anti-rotation plate 118. The non-circular hole 1181 is matched with the second shaft 1222, and the second shaft 1222 passes through the non-circular hole 1181. Through the shaft hole cooperation, the rotation of the second shaft 1222 can be limited, so as to limit the rotation of the entire idler shaft 122, so that the rotation of the first test paper wheel 110 on the idler shaft 122 will be more stable. The limiting piece 117 is arranged on the first shaft 1221 and located at the end of the first shaft 1221, and is used for axially limiting the first test paper wheel 110.

[0077] In some embodiments, as shown in FIG. 3, the first shaft 1221 has a larger diameter than the second shaft 1222; the end surface of the first shaft 1221 close to the second shaft 1222 abuts against the end surface of the damper 121 away from the base 10, and the second shaft 1222 is provided with a clamping groove 1223 provided with a clamping spring 303. It can be understood that the second shaft 1222 is arranged at the center of the shaft of the damper 121, and the second shaft 1222 is collinear with the center of the shaft of the damper 121, wherein the first shaft 1221 has a larger diameter than the second shaft 1222, and the end surface of the first shaft 1221 abuts against the end surface of the damper 121 away from the base 10, thereby limiting the movement of the idler shaft 122 towards the base 10; the surface of the second shaft 1222 is provided with a clamping groove 1223 provided with a clamping spring 303, wherein the clamping groove 1223 is arranged on the side of the anti-rotation plate 118 away from the base 10, and the arrangement of the clamping groove 1223 and the clamping spring 303 can limit the movement of the idler shaft 122 away from the base 10. Therefore, the idler shaft 122 is fixed on the base 10, which further improves the stability of the device.

[0078] In some embodiments, as shown in FIG. 3, the damper 121 is provided with a connecting plate 114, and the first test paper wheel 110 is connected to the connecting plate 114 through the shaft hole cooperation between the connecting hole 1102 and the connecting shaft 1142.

The overall stability is improved, so that the damper 121 can work more stably, and the loosening or damage caused by vibration or impact is reduced.

[0079] It can be understood that the connecting shaft protruding from the connecting plate 114 cooperates with the connecting hole on the first test paper wheel 110 to achieve the transmission of the damping force of the damper 121 to the first test paper wheel 110, and at the same time, the first test paper wheel 110 can be quickly replaced without the aid of tools.

[0080] In a specific embodiment, one end of the connecting plate 114 is fixedly connected to the damper 121, and the other end is provided with a plurality of shafts protruding therefrom and cooperates with the corresponding holes of the first test paper wheel 110 through shaft hole cooperation. The purpose of transmitting the damping force of the damper 121 to the first test paper wheel 110 is achieved, and since the first test paper wheel and the connecting plate 114 are shaft hole cooperated rather than locked by screws, when replacing the first test paper wheel 110, only the limiting part 117 needs to be unscrewed to replace the first test paper wheel 110 (the first test paper wheel 110 is pulled out as a whole along the axis of the idler shaft 122), without the aid of tools, the function of quick installation is achieved. If the quick replacement function is not considered, the connecting plate 114 can not be needed, and the damping force transmission function can be achieved by directly locking the first test paper wheel 110 to the damper 121.

[0082] In some embodiments, as shown in FIG. 2, the first test paper wheel 110 is arranged on the base 10, and the first test paper wheel 110 includes a first test paper shaft 115 and two first baffles 116, the first test paper shaft 115 is used to wind the test paper tape 111; the two first baffles 116 are arranged at both ends of the first test paper shaft 115 respectively, and are used to limit the test paper tape 111 in the axial direction, so as to ensure that the test paper tape 111 is wound on the shaft in an orderly and neat manner, prevent the test paper tape 111 from being offset or loosened in the axial direction, and improve the stability and consistency of the test paper tape 111 release process.

[0083] As shown in FIG. 5, the second test paper wheel 130 is arranged on the base 10, and the second test paper wheel 130 includes a second test paper shaft 133, and the second test paper shaft 133 is used to wind the test paper 131; the second test paper wheel 130 further includes two second baffles 134, and the two second baffles 134 are arranged at both ends of the second test paper shaft 133 respectively, and the two second baffles 134 are used to limit the test paper 131 in the axial direction, so as to orderly collect the used test paper 131, facilitate subsequent processing, and prevent the used test paper 131 from being wrinkled or misaligned during the recycling process.

[0084] As shown in FIG. 6, the film winding wheel 140 is arranged on the base 10, and the film winding wheel 140 includes a film winding shaft 143, and the film winding shaft 143 is used to wind the film body 141; the film winding wheel 140 further includes two film baffles 144, and the two film baffles 144 are arranged at both ends of the film winding shaft 143 respectively, and the two film baffles 144 are used to limit the film body 141 in the axial direction, so as to realize the orderly recycling of the film body 141, facilitate subsequent processing or recycling, and prevent the film body 141 from being wrinkled or misaligned during the recycling process.

[0085] It can be understood that the three wheels all include a central shaft and baffles at both ends, so as to realize the orderly transmission and recycling of the test paper tape 111, the test paper 131 and the film body 141, improve the modular degree of the system, and facilitate component replacement and upgrading.

[0086] The base 10 provides a stable mounting platform for the three wheels, ensures the relative position between the components fixed, improves the stability and accuracy of the whole system, the second test paper wheel 130 is arranged on the base 10, the second test paper wheel 130 can rotate relative to the base 10, the second test paper wheel 130 is connected with the first motor 132, as shown in Figure 12, the first motor 132 includes a first connecting flange and a first output shaft 1322, the second test paper wheel 130 is connected with the first connecting flange, and the first connecting flange is connected with the first output shaft 1322; wherein the first connecting flange includes a first connecting pin shaft 1324, the first connecting pin shaft 1324 is matched with the corresponding hole position of the first output shaft 1322, and the rotation of the output shaft of the first motor 132 drives the rotation of the first connecting flange and the second test paper wheel 130.

[0087] In some embodiments, as shown in Figure 7, the sensor 200 is arranged on the base 10, the sensor 200 is in contact with part of the film body 141, the sensor 200 is used to determine the tension information of the film body 141, and the tension state of the film body 141 can be monitored in real time, wherein the tension information includes that the film body 141 is in a loose state or the film body 141 is in a tight state, thereby providing real-time feedback of the state of the film body 141, and the orderliness and stability of the overall device work can be improved.

[0088] The controller 500 is electrically connected with the sensor 200 and the second motor 142; the controller 500 is used to receive and process the tension information of the sensor 200, according to the tension information of the film body 141, control the second motor 142 to drive the film winding wheel 140 to rotate or stop rotating, to ensure that the film body 141 always maintains appropriate tension. When the film body 141 is in a tight state, it means that the film tearing action is temporarily completed at this time, and there is no need to continue to tear the film, and the second motor 142 stops working. When the film body 141 is in a loose state, it means that the test paper 131 moves a greater distance relative to the film body 141 at this time, and the film tearing action needs to be performed at this time, and the second motor 142 needs to start working. Therefore, when the sensor 200 delivers the tension information as a loose state to the controller 500, the controller 500 controls the second motor 142 to stop working, and when the sensor 200 delivers the tension information as a tight state to the controller 500, the controller 500 controls the second motor 142 to start working.

[0089] Further, as shown in Fig. 9, the sensor 200 is composed of a micro switch 201 and a micro switch fixing plate. The micro switch 201 is locked to the micro switch fixing plate by a screw. When the micro switch 201 is in a free state, it has a certain interference with the film body 141 in a taut state. Once the film body 141 is taut, the micro switch 201 trigger roller is pressed and displaced, thereby triggering the sensor 200. When the film body 141 is in a relaxed state, the micro switch 201 trigger roller starts to return to the free state under the action of its own spring force, and the sensor 200 signal changes, being in a non-trigger state. When the normally recovered film body 141 is in a taut state, the first motor 132 starts to work to drive the first test paper wheel 110 to rotate. The film body 141 changes from a taut state to a relaxed state. At this time, the micro switch 201 signal changes, and the controller 500 receives the micro switch 201 signal, controls the second motor 142 to start working to recover the film body 141. After a period of time, the film body 141 changes from a relaxed state to a taut state, thereby triggering the micro switch 201. The controller 500 receives the micro switch 201 signal again, and controls the second motor 142 to stop working.
