[0002] A calender is a device used to calender paper. During the papermaking process, a calender is needed to improve the overall gloss and flatness of the paper, so that the paper has sufficient smoothness to ensure smooth writing on the writing paper.

[0003] In current papermaking calenders, the distance between the two rollers is generally fixed and cannot be adjusted. It can only adapt to the papermaking requirements of a specific thickness, but cannot be adapted to the use of paper of different thicknesses. It does not have a wide range of applications. When customer needs change, adjustments cannot be made in time and new equipment needs to be purchased, which increases production costs and reduces the economic benefits of the enterprise. Utility Model Content

[0005] The cam is fixedly mounted on the support frame, wherein the cam is secured to the support frame with an axial direction of the first roller and the cam is secured to the support frame with an axial direction of the second roller. The distance a between the rollers is smaller than the distance b between the second bearing and the bottom of the card slot, ensuring that the first pressure roller and the second pressure roller can be tightly pressed together, and a limit baffle is fixedly provided on the end of the second bearing facing away from the second pressure roller, and the limit baffle is pressed against the outer wall of the frame to limit the position of the second bearing, thereby ensuring the stability of the position of the second pressure roller, and the end of one of the second shaft rods passes through the center hole of the limit baffle and is connected to the transmission shaft of the second motor, and the second motor is used to provide power support for the rotation of the second pressure roller, and the lower end of the limit baffle is horizontally fixed with a support plate, and the second motor is fixed on the support plate to ensure the stability of the position of the second motor, and the lower end of the support plate is vertically and symmetrically fixed with a hydraulic rod mechanism, and the lower end of the hydraulic rod mechanism is fixedly connected to the base to ensure the stability of the position of the hydraulic rod mechanism, and the support plate is lifted and lowered under the action of the hydraulic rod mechanism, and then the second pressure roller is driven to lift and lower through the limit baffle and the second bearing, thereby adjusting the distance between the first pressure roller and the second pressure roller to meet the calendering requirements of different paper thicknesses.

[0006] Preferably, a connecting plate is fixedly provided between the upper parts of the frames on both sides of the second pressing roller to improve the strength of the frames, thereby ensuring the stability and reliability of the position of the second pressing roller between the frames.

[0007] Preferably, the first motor and the second motor have the same rotation speed and opposite rotation directions, thereby ensuring a smooth calendering operation on the paper.

[0008] Preferably, the first pressing roller is located directly above the second pressing roller to ensure reliable calendering operation.

[0009] The beneficial effects of the utility model are as follows: the support plate is lifted and lowered under the action of the hydraulic rod mechanism, and then the second pressing roller is driven to lift and lower through the limit baffle and the second bearing, so that the distance between the first pressing roller and the second pressing roller is adjusted to meet the calendering requirements of different paper thicknesses. The utility model is easy to operate, has a wide range of applications, can meet the needs of different customers, and thus improves the economic benefits of the enterprise.

[0015] In order to more clearly understand the technical solution of the present invention, the present invention is further described below with reference to the accompanying drawings.

[0016] like Figure 1-4A papermaking calendering device shown includes a base 1, on which a frame 2 is fixedly arranged vertically and symmetrically to ensure the stable and reliable position of the frame 2. A connecting plate 15 is fixedly arranged between the upper parts of the frame 2 on both sides of the second pressure roller 7 to improve the strength of the frame 2, thereby ensuring the stable and reliable position of the second pressure roller 7 between the frames 2. A first pressure roller 3 is horizontally arranged between the lower parts of the frames 2, and a first shaft 4 at both ends of the first pressure roller 3 passes through the center of the first bearing 5 on the frame 2 and is tightly connected to the first bearing 5, so that the first pressure roller 3 rotates smoothly. One end of the first shaft 4 is connected to the transmission shaft of the first motor 6, and the first motor 6 provides power support for the rotation of the first pressure roller 3. A second pressure roller 7 is horizontally arranged between the upper parts of the frames 2, and the paper is calendered by the rolling of the first pressure roller 3 and the second pressure roller 7. The second shaft 8 at both ends of the second pressure roller 7 passes through the center of the second bearing 9 and is tightly connected to the second bearing 9. The second pressing roller 7 is tightly connected to the frame 2 so that the second pressing roller 7 can rotate smoothly. A slot 10 is vertically opened in the middle position of the upper part of the frame 2. The second bearing 9 is arranged in the slot 10 and the outer diameter of the second bearing 9 is the same as the width of the slot 10, ensuring that the second bearing 9 can only move in the vertical direction, thereby avoiding the position deflection of the second pressing roller 7. The distance a between the first pressing roller 3 and the second pressing roller 7 is smaller than the distance b between the second bearing 9 and the bottom of the slot 10, ensuring that the first pressing roller 3 and the second pressing roller 7 can be tightly pressed together. The first pressing roller 3 is located directly above the second pressing roller 7 to ensure that the calendering operation is reliable. A limit baffle 11 is fixedly provided on the end of the second bearing 9 away from the second pressure roller 7. The limit baffle 11 is against the outer wall of the frame 2 to limit the position of the second bearing 9, thereby ensuring the stability of the position of the second pressure roller 7. The end of one of the second shafts 8 passes through the center hole of the limit baffle 11 and is connected to the transmission shaft of the second motor 12, and the second motor 12 provides power support for the rotation of the second pressure roller 7. The lower end of the limit baffle 11 is horizontally fixed with a support plate 13, and the second motor 12 is fixed It is fixed on the support plate 13 to ensure the stability of the position of the second motor 12. A hydraulic rod mechanism 14 is vertically and symmetrically fixed at the lower end of the support plate 13. The lower end of the hydraulic rod mechanism 14 is fixedly connected to the base 1 to ensure the stability of the position of the hydraulic rod mechanism 14. The support plate 13 is lifted and lowered under the action of the hydraulic rod mechanism 14, and then the second pressing roller 7 is driven to lift and lower through the limit baffle 11 and the second bearing 9, so as to adjust the distance between the first pressing roller 3 and the second pressing roller 7 to meet the calendering requirements of different paper thicknesses.

[0017] The first motor 6 and the second motor 12 have the same rotation speed and opposite rotation directions, thereby ensuring a smooth calendering operation on the paper.
