[0014] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0015] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0016] like Figure 1-4A roller structure shown includes a winding roller 1 and a pressure roller 2. Slots 3 for inserting the ends of the pressure roller 2 are provided at both ends of the winding roller 1. A bearing box 4 is provided outside each pressure roller 2. The pressure roller 2 and the bearing box 4 rotate together. The pressure roller 2 is provided with a socket 6 corresponding to the position of the slot 3 along the insertion direction and a connecting rod 5 located in the socket 6. The two ends of the connecting rod 5 extend to the outside of the two ends of the socket 6 respectively. The inner end of the connecting rod 5 is fixed to the winding roller 1. The outer end of the connecting rod 5 is provided with a locking structure for squeezing the pressure roller 2 toward the winding roller 1 so that the two are locked. The locking structure can be a locking nut or a latch structure. The use of the latch structure requires the use of external force to press the pressure roller 2 to an appropriate position. A socket is opened in advance on the connecting rod 5, and the latch is installed, or a retaining spring is used for fixing.

[0017] The outer end of the connecting rod 5 is provided with an adjusting nut 7 for pressing the clamping roller 2 against the winding roller 1. The outer wall of one end of the connecting rod 5 facing the adjusting nut 7 is at least partially provided with an external thread. The length of the external thread is determined according to actual conditions. It is necessary to ensure that the clamping roller 2 and the winding roller 1 can be locked by the adjusting nut 7.

[0018] The clamping roller 2 and the bearing box 4 can be pressed against the winding roller 1 by adjusting the nut 7, which is easy to operate. When the adjusting nut 7 is tightened, the clamping roller 2 and the bearing box 4 will be squeezed together toward the slot 3, and the slot 3 has an inner conical surface 10 inside, and the outer end of the clamping roller 2 is provided with an outer conical surface 11. The two will be pressed tighter after being squeezed, and the winding roller 1, the clamping roller 2 and the bearing box 4 can be assembled by an adjusting nut 7.

[0019] The two ends of the winding roller 1 are fixed or integrally provided with a pressure cover 8, a slot 3 is provided in the pressure cover 8 and the opening of the slot 3 faces outward, a threaded hole 9 connected to the slot 3 is provided in the pressure cover 8, and the outer wall of one end of the connecting rod 5 connected to the threaded hole 9 of the pressure cover 8 is at least partially provided with an external thread. In this embodiment, it is preferred that the threaded hole 9 is coaxially arranged with the slot 3, and the connecting rod 5 can be a whole threaded rod, or only the two ends are partially provided with external threads.

[0020] The inner wall of the slot 3 is set as an inner cone 10, and the width of the inner cone 10 gradually increases from the inside to the outside. The outer wall of the end where the clamping roller 2 is connected to the slot 3 is set as an outer cone 11. The shapes of the inner cone 10 and the outer cone 11 are adapted, and the structure of the cone can ensure the clamping effect.

[0021] The two pressing rollers 2 have the same structure as the winding roller 1, wherein one end of the pressing roller 2 away from the winding roller 1 is provided with a coupling 12 and connected to the motor, and the other pressing roller 2 is the driven end, and the bearing boxes 4 outside the two pressing rollers 2 are fixed to the wire cutting frame of the slicer through a cover plate.

[0022] The bearing box 4 includes a box body 14 , in which a plurality of coaxially arranged bearings 13 are arranged. The pressure roller 2 rotates in cooperation with the plurality of bearings 13 , and the pressure roller 2 is relatively fixed in a horizontal direction and will not slip relative to the box body 14 .

[0023] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
