Description

Technical Field

[0001] This utility model relates to the field of reagent kit production technology, specifically a multi-specification cutting device for reagent kits. Background Technology

[0002] A test kit is a box used to hold chemical reagents for detecting chemical components, drug residues, virus types, etc. Some test kits are made of paper, which requires cutting cardboard to fold into test kits.

[0003] Chinese utility model patent with announcement number CN220639062U discloses a cutting device for the production of a test kit, including an operating table, a U-shaped bracket fixedly connected to the top surface of the operating table, a cutting mechanism inside the U-shaped bracket, and a positioning mechanism on the right side of the U-shaped bracket. The positioning mechanism includes a power unit; the power unit includes an L-shaped baffle, a first motor, and a connecting block. The connecting block is threaded onto the outer surface of the output shaft of the first motor.

[0004] However, the cutting device used in the production of the test kit of this utility model uses a mold plate to press the cardboard with the elasticity of a return spring to prevent the cardboard from warping during the cutting process. When the cardboard is uneven in texture or has foreign objects on its surface, the elasticity of the return spring may not be able to ensure that the mold plate always presses the cardboard stably, which may cause the cardboard to warp locally during the cutting process, affecting the cutting accuracy. Therefore, a multi-specification cutting device for test kits is proposed to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-size cutting device for reagent kits includes a workbench, a vertical plate fixedly connected to the top of the workbench, a straight module fixedly connected to the top of the vertical plate, and a cutting structure disposed at the bottom of the straight module. The cutting structure includes a fixing plate disposed on the lower surface of the straight module and a cutter fixedly connected to the bottom of the fixing plate. The top of the fixing plate is provided with a rotation driving adjustment mechanism, and the outside of the adjustment mechanism is provided with an adsorption structure for adsorbing and fixing cardboard.

[0008] The adjustment mechanism includes an electric push rod disposed at the bottom of the linear module. A mounting box is fixedly connected to the output end of the electric push rod. A rotating shaft extending to the outside of the mounting box is rotatably connected inside the mounting box. A drive motor is fixedly installed inside the mounting box.

[0009] The adsorption structure includes a piston cylinder fixedly connected to the outside of the mounting box and suction tubes fixedly connected to the inside of the workbench. There are multiple suction tubes, and a connecting pipe is fixedly connected between two adjacent suction tubes. An air extraction structure is provided inside the piston cylinder.

[0010] Furthermore, the linear module and the electric push rod are fixedly connected by a mounting plate, and a bearing adapted to the rotating shaft is fixedly installed inside the mounting box.

[0011] Furthermore, the fixing plate is fixedly connected to the bottom end of the rotating shaft and located at the top of the worktable.

[0012] Furthermore, the top of the straw is fixedly connected to a plurality of suction nozzles, which are distributed at equal intervals on the top of the straw and are flush with the top of the workbench.

[0013] Furthermore, the air extraction structure includes a piston block slidably connected inside the piston cylinder, a piston rod extending to the outside of the piston cylinder is fixedly connected to the bottom of the piston block, a connecting plate is fixedly connected to the bottom end of the piston rod, and a return spring is fixedly connected between the connecting plate and the piston cylinder, the return spring being connected to the outside of the piston rod.

[0017] Compared with the prior art, this utility model provides a multi-size cutting device for reagent kits, which has the following beneficial effects:

[0018] 1. The multi-size cutting device of this kit, when started by the drive motor, drives the rotating shaft to rotate through the transmission of worm gear and worm wheel, thereby causing the fixed plate and cutter to rotate around the rotating shaft, realizing the adjustment of the cutter angle. It can maintain the angle stability after the cutter angle is adjusted, avoiding the cutter angle deviation during the cutting process, thus improving the accuracy and stability of cutting.

[0019] 2. This kit features a multi-size cutting device. As the mounting box moves down with the electric push rod, the rollers on the connecting plate first contact the cardboard, pushing the stopper rod and piston block upward. This creates negative pressure inside the piston cylinder, which then adsorbs and fixes the cardboard through the delivery tube, suction tube, and suction nozzle. Compared to the traditional spring compression method, negative pressure adsorption can act more evenly on the surface of the cardboard. Even if the texture is uneven or there are foreign objects on the surface, it can effectively prevent the cardboard from warping during cutting, ensuring cutting accuracy. It achieves linkage between adsorption and cutting actions, saving energy and ensuring high operational synchronization. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 5 This embodiment of a multi-specification cutting device for a reagent kit includes a workbench 1, a vertical plate 2 fixedly connected to the top of the workbench 1, a straight module 3 fixedly connected to the top of the vertical plate 2, and a cutting structure 4 disposed at the bottom of the straight module 3. The cutting structure 4 includes a fixing plate 41 disposed on the lower surface of the straight module 3 and a cutter 42 fixedly connected to the bottom of the fixing plate 41. The top of the fixing plate 41 is provided with a rotation driving adjustment mechanism 5, and the outside of the adjustment mechanism 5 is provided with an adsorption structure 6 for adsorbing and fixing cardboard. The straight module 3 is a conventional technology known to the public in the prior art, so its specific structural composition and working principle will not be elaborated on in the text.

[0028] The adjustment mechanism 5 includes an electric push rod 51 located at the bottom of the linear module 3. A mounting box 52 is fixedly connected to the output end of the electric push rod 51. A rotating shaft 53 extending to the outside of the mounting box 52 is rotatably connected inside the mounting box 52. A drive motor 54 is fixedly installed inside the mounting box 52. A worm gear 55 is fixedly connected to the output shaft of the drive motor 54. A worm wheel 56 meshing with the worm gear 55 is fixedly installed outside the rotating shaft 53. The adjustment mechanism 5 allows for flexible adjustment of the cutter 42 angle. The drive motor 54 drives the worm gear 55 to rotate, and the worm gear 55 meshes with the worm wheel 56, causing the rotating shaft 53 to drive the fixed plate 41 and the cutter 42 to rotate. This adapts to the cutting angle requirements of different reagent kit sizes, improving the device's versatility.

[0029] Specifically, the linear module 3 and the electric push rod 51 are fixedly connected by a mounting plate, and the mounting box 52 has a bearing that is compatible with the rotating shaft 53 fixedly installed inside.

[0030] It should be noted that the fixing plate 41 is fixedly connected to the bottom end of the rotating shaft 53 and is located on the top of the worktable 1.

[0031] It is worth mentioning that a flexible telescopic rod 7 is rotatably connected to the bottom of the fixed plate 41. A connecting plate is fixedly connected to the bottom end of the flexible telescopic rod 7, and an abutment wheel 8 is rotatably connected to the bottom of the connecting plate. During the cutting process, the abutment wheel 8 can contact the surface of the cardboard, playing a certain role in pressing and guiding. The flexible telescopic rod 7 can adaptively extend and retract according to the thickness of the cardboard and the surface unevenness, ensuring that the abutment wheel 8 always maintains good contact with the surface of the cardboard, further improving the stability of the cardboard during the cutting process and reducing cutting errors.

[0032] In this embodiment, the adsorption structure 6 includes a piston cylinder 61 fixedly connected to the outside of the mounting box 52 and a suction tube 63 fixedly connected to the inside of the workbench 1. There are multiple suction tubes 63, and a connecting pipe 64 is fixedly connected between two adjacent suction tubes 63. An air extraction structure is provided inside the piston cylinder 61.

[0033] The top of the straw 63 is fixedly connected to a number of suction nozzles, which are distributed at equal intervals on the top of the straw 63 and are flush with the top of the workbench 1.

[0034] Specifically, the suction structure includes a piston block 62 slidably connected inside the piston cylinder 61. A stopper rod 65 extending to the outside of the piston cylinder 61 is fixedly connected to the bottom of the piston block 62. A connecting plate 66 is fixedly connected to the bottom end of the stopper rod 65. A return spring 68 is fixedly connected between the connecting plate 66 and the piston cylinder 61, and the return spring 68 is connected to the outside of the stopper rod 65. The adsorption structure 6 generates negative pressure through the suction structure inside the piston cylinder 61, which adsorbs and fixes the cardboard through the delivery pipe 69, suction pipe 63, and suction nozzle. Compared to the traditional spring compression method, negative pressure adsorption can act more evenly on the surface of the cardboard. Even in cases of uneven texture or foreign matter on the surface, it can effectively prevent the cardboard from warping during cutting, ensuring cutting accuracy. After cutting, the elasticity of the return spring 68 allows the piston block 62 to automatically return to its original position, releasing the adsorption on the cardboard and facilitating the removal of the cut cardboard. This allows for rapid adsorption and release of the cardboard.

[0035] It should be noted that a roller 67 is rotatably connected to the bottom of the connecting plate 66, and a conveying pipe 69 is fixedly connected between the piston cylinder 61 and one of the suction tubes 63. When the mounting box 52 moves down with the electric push rod 51, the roller 67 on the connecting plate 66 first contacts the cardboard, pushing the stopper rod 65 and the piston block 62 upward, causing a negative pressure to be generated inside the piston cylinder 61, thus realizing the linkage between the suction action and the cutting action.

[0036] It is worth mentioning that the bottom of the workbench 1 is fixedly connected with four support legs, which are arranged in a rectangular shape at the bottom of the workbench 1.

[0037] The working principle of the above embodiments is as follows:

[0038] In use, place the cardboard on the workbench 1 so that it covers the suction nozzle at the top of the straw 63. At this time, there is no negative pressure in the suction structure 6. Start the drive motor 54 of the adjustment mechanism 5. Through the worm gear 55 and worm wheel 56, drive the rotating shaft 53 and the fixed plate 41 to rotate, so that the cutter 42 is adjusted to the required angle. Start the linear module 3 and the electric push rod 51 through the controller. When the mounting box 52 moves down, the roller 67 first contacts the cardboard and pushes the stopper rod 65 to move up. The piston block 62 forms a negative pressure in the piston cylinder 61. The cardboard is suctioned and fixed through the delivery pipe 69, the straw 63 and the suction nozzle. The linear module 3 drives the cutting structure 4 to move laterally, and the cutter 42 moves down to cut. The abutment wheel 8 of the elastic telescopic rod 7 presses the cardboard simultaneously, which in conjunction with the suction enhances stability. After cutting, the electric push rod 51 drives the mounting box 52 to move up. The return spring 68 pushes the piston block 62 to return to its original position, the negative pressure is released, the cardboard is removed, and the device returns to its initial state.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
