Description

Technical Field

[0001] This utility model relates to the field of reagent box press technology, and in particular to a reagent box press. Background Technology

[0002] The shelling machine is used in the production process to press the test strips into plastic casings. After the test strips are inserted into the plastic bottom casing, the top cover is aligned with the bottom casing cover, and then the shelling machine conveyor belt is placed on it. The casing is then pressed and closed by rubber rollers that move at the same speed as the conveyor belt. However, existing reagent kit shelling machines may have the problem of damaging the reagent kits due to improper pressure adjustment.

[0003] For example, a reagent kit pressing machine is disclosed in Chinese utility model patent with announcement number CN221247605U. Although the solution is to press the reagent kit onto the support plate by the pressure roller and press it by the pressure roller to complete the pressing of the reagent kit, the pressure roller, sliding block and threaded rod are fixedly connected. When the pressure roller encounters reagent kits of different heights, stress collisions can easily cause damage to the reagent kit.

[0004] In view of this, a reagent kit shelling machine that can solve the above problems is proposed. Utility Model Content

[0005] To address the technical problem of buffering in reagent kit shelling machines, this utility model provides a reagent kit shelling machine.

[0006] This utility model is achieved using the following technical solution: a reagent kit shelling machine, comprising a base, with support plates fixedly connected to both upper sides of the base, and slots respectively opened on the upper sides of the two support plates. A locking block is slidably connected to the inner side of each slot, and a pressure roller is rotatably connected between the two locking blocks. A threaded rod is fixedly connected to the upper side of each locking block, and a limit block is installed on the upper side of each slot. The threaded rod on each side is slidably connected to the limit block, and a spring is fixedly connected to the upper side of each limit block. The upper end of each threaded rod passes upward along the center line of the spring, and a nut is threaded onto the upper end of each threaded rod. The lower side of the nut is rotatably connected to the upper end of the spring. A reagent kit feeding mechanism is provided on the upper side of the base, and a connecting drive mechanism is provided on one side of one of the support plates, and a pressure roller drive mechanism for rotating the pressure roller is provided on one side of the other support plate.

[0007] As a further improvement to the above solution, the reagent feeding mechanism includes a conveyor belt disposed between the two support plates, and a second gear is fixedly connected to one end of the conveyor belt near the round roller of the pressure roller.

[0008] The above technical solution enables the drive of the conveyor belt and the drive of the pressure roller to be linked, so that there is no speed difference between the two. When the shell pressing operation is performed, friction slippage or even splashing problems caused by the difference in the speed of the two can be avoided. As a further improvement to the above solution, a servo motor is installed on one of the support plates away from the second gear, and the output end of the servo motor is connected to the round rod.

[0009] As a further improvement to the above solution, the connecting drive mechanism includes a first gear rotatably connected to the outer side of the support plate, the first gear meshing with the second gear, a first connecting plate rotatably connected to the outer side of the first gear, and a swing gear mechanism provided on the inner side of the first connecting plate.

[0010] As a further improvement to the above scheme, the swing gear mechanism includes a fourth gear rotatably connected to the inner side of the first connecting plate, and a second connecting plate rotatably connected to the outer side of the fourth gear.

[0011] As a further improvement to the above solution, the pressure roller driving mechanism includes a third gear rotatably connected to one side of the second connecting plate, and the third gear is fixedly connected to one end of the pressure roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a spring between the nut and the upper side of the limiting block. When the pressure roller encounters reagent kits of different heights and the height fluctuates, the spring can buffer the impact. By adjusting the position of the nut on the threaded rod, different pressure intensities can be set, thereby effectively reducing the problem of reagent kit damage caused by excessive pressure. 2. This utility model uses a servo motor to drive gears No. 1, No. 2, No. 3 and No. 4 to rotate simultaneously. When the pressure roller moves up and down along the groove under the action of the spring, gear No. 2 can also drive the pressure roller to rotate through gear No. 3. The speed of the pressure roller is the same as the speed of the conveyor belt, which avoids relative sliding friction and overturning of the reagent kit during the shell pressing process due to the speed difference between the two, and helps to improve the quality of shell pressing.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0016] Example: Please combine Figure 1 - Figure 3 The reagent kit shelling machine of this embodiment includes a base 1, and support plates 2 are fixedly connected to both upper sides of the base 1. The upper sides of the two support plates 2 are respectively provided with slots 12. In this embodiment, the inner side of the slots 12 is provided with a limiting groove. Please combine Figure 2 As shown, each slot 12 has a slidably connected card block 17 on its inner side, and card plates are provided on both sides of the card block 17, which slide in cooperation with the limiting groove. Please combine Figure 2 As shown, a pressure roller 8 is rotatably connected between the two locking blocks 17. The pressure roller 8 is a circular rubber roller. Please combine Figure 1 As shown, each locking block 17 is fixedly connected to a threaded rod 13 on its upper side, and a limiting block 11 is installed on the upper side of each locking slot 12. The limiting block 11 plays the role of support and limiting, and is detachably connected by bolts. Please combine Figure 1 As shown, each threaded rod 13 is slidably connected to the limiting block 11. A spring 9 is fixedly connected to the upper side of each limiting block 11. The upper end of each threaded rod 13 passes upward along the center line of the spring 9. A nut 10 is threadedly sleeved on the upper end of each threaded rod 13. The lower side of the nut 10 is rotatably connected to the upper end of the spring 9. It should be noted that in this embodiment, a rotating washer is provided on the lower side of the nut 10, and the spring 9 is fixedly connected to the lower side of the washer. Please combine Figure 1 As shown, a reagent kit feeding mechanism is provided on the upper side of the base 1, and a connecting drive mechanism is provided on one side of one of the support plates 2, while a pressure roller drive mechanism for rotating the pressure roller 8 is provided on one side of the other support plate 2.

[0017] Please combine Figure 1 As shown, the reagent kit feeding mechanism includes a conveyor belt 7 disposed between two support plates 2, and a second gear 5 is fixedly connected to one end of the conveyor belt 7 near the round roller 8.

[0018] Please combine Figure 2 As shown, a servo motor 16 is installed on one of the support plates 2 away from the second gear 5. The output end of the servo motor 16 is connected to the round rod. An LED control panel is installed on the support plate 2 on the same side. The LED control panel is electrically connected to the servo motor 16.

[0019] Please combine Figure 1 As shown, the connecting drive mechanism includes a first gear 4 rotatably connected to the outside of the support plate 2. The first gear 4 meshes with the second gear 5. The outside of the first gear 4 is rotatably connected to a first connecting plate 3. A swing gear mechanism is provided on the inner side of the first connecting plate 3.

[0020] Please combine Figure 1 As shown, the swing gear mechanism includes a fourth gear 15 rotatably connected to the inner side of the first connecting plate 3, and a second connecting plate 14 rotatably connected to the outer side of the fourth gear 15. It should be noted that the fourth gear 15 is in a swing state when the pressure roller 8 is buffered up and down. by Figure 1 For example, when the pressure roller 8 drives the locking block 17 to slide upward, the second connecting plate 14 rotates counterclockwise, while the first connecting plate 3 rotates clockwise. When the pressure roller 8 drives the locking block 17 to slide downward, the second connecting plate 14 rotates clockwise, while the first connecting plate 3 rotates counterclockwise. Please combine Figure 1 As shown, the pressure roller drive mechanism includes a third gear 6 that is rotatably connected to one side of the second connecting plate 14, and the third gear 6 is fixedly connected to one end of the pressure roller 8.

[0021] The implementation principle of a reagent kit shelling machine in this embodiment is as follows: the servo motor 16 drives the conveyor belt 7 to rotate, which in turn drives the second gear 5 at one end to rotate. The rotation of the second gear 5 drives the first gear 4 to rotate, and the first gear 4 drives the fourth gear 15 to rotate through meshing. The fourth gear 15 drives the third gear 6 to rotate, thereby achieving the effect of driving the pressure roller 8 to rotate through the third gear 6. When the reagent kit transported on the conveyor belt 7 experiences a slight height change, causing the pressure roller 8 to slightly collide, the pressure roller 8 can slide upward along the slot 12 through the locking block 17, and be pushed upward by the threaded rod 13 to cause the spring 9 to deform, thereby achieving buffering. When the third gear 6 slides upward together with the pressure roller 8 and the locking block 17, due to the control effect of the first connecting plate 3 and the second connecting plate 14 on the fourth gear 15 and the third gear 6, the second connecting plate 14 swings counterclockwise while the first connecting plate 3 swings clockwise, achieving adaptive balance.

[0022] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
