[0021] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0022] like Figure 1-6 FIG. 1 is a structural diagram of a roll assembly provided by an embodiment of the present invention. The roll assembly includes a front cover 1 and further includes:

[0023] A first material roll box 2 and a second material roll box 3 are respectively arranged at both ends of the front cover 1. The first material roll box 2 is connected to the front cover 1 to form a storage space for placing a drive shaft 4. Consumables 5 are installed on the drive shaft 4. The second material roll box 3 is provided with a follower for cooperating with the drive shaft 4.

[0024] In an embodiment of the present utility model, the consumables 5 are installed on the drive shaft 4 and then placed in the accommodating space formed by the connection between the first coil box 2 and the front cover 1, and then the drive shaft 4 is driven to rotate by a single driving source, thereby realizing the operation of wiping and rolling. This solves the problem that the conventional nucleic acid extractor mostly manually takes the consumables to wipe the needle of the extraction device, which increases the time consumed in nucleic acid extraction.

[0025] In one example of the present invention, the follower is usually a shaft used in conjunction with the drive shaft 4. Of course, the drive shaft 4 can sometimes be used instead, which is not elaborated here. The drive shaft 4 is driven to rotate by a single driving source, and the other end of the consumable 5 is connected to the follower, thereby driving the rotation of the follower to achieve winding.

[0026] Furthermore, as a preferred embodiment of the present invention, the first material roll box 2 and the front cover 1 are detachably connected, and the accommodating space for placing the drive shaft 4 formed by the connection between the first material roll box 2 and the front cover 1 can also accommodate consumables 5.

[0027] In one embodiment of the present invention, specifically, the consumable material 5 is sleeved on the transmission shaft 4. It can be understood that the second coil box 3 and the front cover 1 are also detachably connected, and the second coil box 3 and the front cover 1 are connected to form a placement space for placing the driven member.

[0028] Furthermore, as a preferred embodiment of the present invention, the coil assembly further includes a ferrule 6, and two ferrules 6 are provided, which are respectively mounted on the drive shaft 4 and a driven member for cooperating with the drive shaft 4. Specifically, by providing the ferrule 6, the consumable material 5 can be rolled up thereon, and then the ferrule 6 is mounted on the drive shaft 4 to form a rolled-up consumable material 5. The other end of the consumable material 5 is connected to the ferrule 6 mounted on the driven member, so that the drive shaft 4 can be driven to rotate by a single drive source, thereby achieving an unwinding or rolling-up operation.

[0029] Furthermore, as a preferred embodiment of the present invention, a limiting hole 7 is opened on one side of the first coil box 2 and the second coil box 3. Specifically, the limiting hole 7 opened on one side of the first coil box 2 is used for the transmission shaft 4 to rotate without offset, and the limiting hole 7 opened on one side of the second coil box 3 is used for the follower to rotate without offset.

[0030] Furthermore, as a preferred embodiment of the present invention, the coil assembly also includes a fixing part 8 for connecting the front cover 1 to the first coil box 2 and the second coil box 3 respectively. Specifically, by providing the fixing part 8, the detachable connection between the first coil box 2 and the front cover 1 and the detachable connection between the second coil box 3 and the front cover 1 can be achieved.

[0031] Furthermore, as a preferred embodiment of the present invention, the contact surface between the front cover 1 and the first roll material box 2 and the contact surface between the front cover 1 and the second roll material box 3 are both provided with multiple buckles 9. Specifically, by providing multiple buckles 9, further locking can be performed in conjunction with the fixing member 8, making installation and removal simple and convenient.

[0032] The implementation principle of this embodiment is: when in use, by placing the consumables 5 in the accommodating space, the front cover 1, the first roll box 2 and the second roll box 3 can be further locked by using multiple snap hooks 9 and fixing parts 8, and then the transmission shaft 4 can be driven to rotate directly by manual operation or a single driving source such as a motor, thereby realizing the operation of wiping and rolling, which solves the problem that the existing nucleic acid extraction instrument mostly manually takes the consumables to wipe the needle of the extraction equipment, which increases the time spent on nucleic acid extraction.
