DETAILED DESCRIPTION

[0017] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] like Figure 1-2 As shown, a calender comprises: a workbench 1, and a bracket 3 is symmetrically fixedly connected to the lower end surface of the workbench 1.

[0019] A third roller 7 is rotatably provided above the workbench 1, and a first support rod 4 is fixedly connected to the upper end surface of the workbench 1 and at positions near both ends, and a first roller 5 is rotatably connected to the inner side of the first support rod 4, and a second roller 9 is rotatably provided between the third roller 7 and the two first rollers 5, and a second support rod 6 is fixedly connected to the upper end surface of the workbench 1 and at positions corresponding to the second rollers 9, and the inner side of the second support rod 6 is rotatably connected to the second roller 9.

[0020] As for how the third roller 7 is rotatably arranged above the workbench 1: a sleeve 17 is fixedly connected to the upper end surface of the workbench 1, a third support rod 8 is arranged above the sleeve 17, and the inner side of the third support rod 8 is rotatably connected to the third roller 7.

[0021] Paper 10 is arranged between the third roller 7, the second roller 9 and the first roller 5. The paper 10 enters from the right side of the first roller 5, passes through the bottom of the first roller 5 to enter the bottom of the second roller 9, enters from the bottom of the second roller 9 to the top of the third roller 7, then passes through the bottom of another second roller 9 and the bottom of another first roller 5, and is sent out from the left side of the first roller 5.

[0022] During the calendering process, the paper 10 is easily in a relaxed state, which affects the calendering effect. At this time, the position of the third roller 7 needs to be adjusted.

[0023] A motor 2 is fixedly installed on the lower end surface of the workbench 1, and the output shaft of the motor 2 passes through the workbench 1 and is fixedly connected to the rotating drum 11. A plurality of lifting grooves are arranged on the outer curved surface of the rotating drum 11, and two adjacent lifting grooves are connected. Each lifting groove includes a first slide groove 1101 and a second slide groove 1102. The first slide groove 1101 is vertically opened on the outer curved surface of the rotating drum 11, and one side of the first slide groove 1101 and a position close to its upper end is connected to the second slide groove 1102. The second slide groove 1102 is inclined, and the lower end of the second slide groove 1102 is connected to the lower end of the first slide groove 1101 of another lifting groove.

[0024] The depth of the second slide groove 1102 at the upper end is greater than that of the first slide groove 1101 of the same mechanism, the depth of the second slide groove 1102 at the lower end is less than that of the first slide groove 1101 of the adjacent mechanism, and the depth of the second slide groove 1102 gradually decreases from top to bottom.

[0025] The interior of the sleeve 17 is hollow, and the moving block 13 is slidably connected to the interior of the sleeve 17. A first notch is opened in the side wall of the sleeve 17. A connecting rod 12 is fixedly connected to the side of the moving block 13. The connecting rod 12 passes through the first notch and is slidably connected to the lifting groove. The upper end surface of the moving block 13 is fixedly connected to a fixing rod 15. The fixing rod 15 passes through one side of the sleeve 17 and is fixedly connected to the third support rod 8. A spring 14 is wound around the outside of the fixing rod 15. The bottom end of the spring 14 is fixedly connected to the moving block 13, and the upper end of the spring 14 is fixedly connected to the inner wall of the upper end of the sleeve 17.

[0026] Start the motor 2, and the output shaft of the motor 2 drives the rotating drum 11 to rotate, so that the connecting rod 12 slides in the vertical direction along the lifting groove. When the connecting rod 12 slides in the second slide groove 1102, because the second slide groove 1102 is inclined, the second slide groove 1102 can drive the connecting rod 12 to slide at different heights, which can drive the moving block 13, the spring 14, the fixed rod 15, the third support rod 8, and the third roller 7 to slide as a whole at different heights.

[0027] When the connecting rod 12 slides to the lowermost end of the second slide groove 1102, because the depth of the groove of the second slide groove 1102 at the lower end is smaller than the depth of the first slide groove 1101 of the adjacent mechanism, the connecting rod 12 will then slide into the first slide groove 1101 of the adjacent mechanism. Under the action of the rebound force of the spring 14, the connecting rod 12 moves upward along the first slide groove 1101. Because the depth of the groove of the second slide groove 1102 at the upper end is greater than the depth of the first slide groove 1101 of the same mechanism, when the connecting rod 12 slides to the upper end of the first slide groove 1101, it will then slide into the second slide groove 1102 on the same mechanism.

[0028] In order to prevent the moving block 13 from sliding after moving to the appropriate position, a second notch is opened on the other side wall of the sleeve 17, and the other side of the moving block 13 is fixedly connected with a screw rod 16, which passes through the second notch and is threadedly connected with a nut. The nut fits against the outer wall of the sleeve 17 to fix the moving block 13.

[0029] Before the moving block 13 slides, the nut is loosened to allow the moving block 13 to slide. After the moving block 13 moves to a suitable position, the nut is tightened to fix the moving block 13.

[0030] Working principle:

[0031] Start the motor 2, and the output shaft of the motor 2 drives the rotating drum 11 to rotate, so that the connecting rod 12 slides in the vertical direction along the lifting groove. When the connecting rod 12 slides in the second slide groove 1102, because the second slide groove 1102 is inclined, the second slide groove 1102 can drive the connecting rod 12 to slide at different heights, which can drive the moving block 13, the spring 14, the fixed rod 15, the third support rod 8, and the third roller 7 to slide as a whole at different heights.

[0032] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
