[0023] Please refer to Figures 1-4, an embodiment provided by the present utility model: a lifting and adjusting structure of a calender roll, including a lower machine base 1 and a frame 2 fixedly installed on the upper surface of the lower machine base 1. A first roll 3 is arranged between the frames 2. Both ends of the first roll 3 are installed with bearing seats. Among them, the bearing is installed in the bearing seat, and the inner hole of the bearing is sleeved on the shaft neck bearing positions at both ends of the first roll 3. The bearing of the first roll 3 is in limit sliding connection with the frame 2. A second roll 4 is arranged above the first roll 3. The bearing seats on both sides of the second roll 4 are fixedly installed on the frame 2, that is, the second roll 4 is fixed. In order to automatically and freely adjust the distance between the first roll 3 and the second roll 4, a first roll distance adjusting component 8 is arranged below the bearing seats on both sides of the first roll 3;

[0024] A third roll 5 is arranged above the second roll 4. In order to adjust the distance between the second roll 4 and the third roll 5, a second roll distance adjusting component 10 is arranged between the bearing seats at both ends of the second roll 4 and the third roll 5;

[0025] A fourth roll 6 is arranged above the third roll 5. A third roll distance adjusting component 11 is arranged between the bearing seats at both ends of the third roll 5 and the fourth roll 6. The third roll distance adjusting component 11 can adjust the distance between the third roll and the fourth roll 6;

[0026] Furthermore, in order to facilitate the adjustment of the roll distance between the fourth roll 6 and the fifth roll 7, a fifth roll 7 is installed on the back surface of the fourth roll 6 and on the frame 2. Thrust roll distance adjusting components 12 are installed on the back surfaces of the bearing seats at both ends of the fifth roll 7.

[0027] In this embodiment, specifically referring to the attached Figure 2 As shown in the figure, the first roll distance adjusting component 8 includes a distance adjusting motor 801 fixedly installed on the outer wall of one side of the frame 2. The output end of the distance adjusting motor 801 is fixedly connected with a first reduction gearbox 802. The output end of the first reduction gearbox 802 is fixedly installed with a distance adjusting screw rod 803. A distance adjusting slider 804 is threadedly connected to the distance adjusting screw rod 803;

[0028] Furthermore, the upper surface of the distance adjusting slider 804 is designed with a slope surface structure;

[0029] In this structural design, when it is necessary to adjust the distance between the first roller 3 and the second roller 4, the distance-adjusting motor 801 can be rotated. When the distance-adjusting motor 801 rotates, it drives the distance-adjusting lead screw 803 to rotate slowly through a first-stage reduction gearbox 802. Since a distance-adjusting slider 804 is threadedly connected to the distance-adjusting lead screw 803, when the distance-adjusting lead screw 803 rotates, the distance-adjusting slider 804 thereon will move to one side. Since the upper surface of the distance-adjusting slider 804 is designed as an inclined surface structure, when the distance-adjusting slider 804 moves towards the bearing seat side, it will push against the bearing seat through the inclined surface, thereby raising the first roller 3 by pushing against the bearing seat. When the first roller 3 rises, the second roller 4 remains stationary. At this time, the distance between the first roller 3 and the second roller 4 is reduced, so that the use effect of automatically adjusting the roller distance can be achieved;

[0030] Similarly, when it is necessary to adjust the roller distance between the second roller 4 and the third roller 5, the second-stage roller distance adjusting assembly 10 works, so that the slider of the second-stage roller distance adjusting assembly 10 pushes against the third roller 5 to rise. The second roller 4 remains stationary. At this time, the distance between the second roller 4 and the third roller 5 increases, achieving the purpose of adjusting the roller distance between the second roller 4 and the third roller 5;

[0031] Since the slider of the third-stage roller distance adjusting assembly 11 does not displace, when the third roller 5 moves upward, it will simultaneously push the fourth roller 6 and the bearing seat on the fourth roller to move up and down synchronously through the third-stage roller distance adjusting assembly 11. Since the slider of the distance-adjusting mechanism of the fourth roller 6 does not slide back and forth, the roller distance between the third roller 5 and the fourth roller 6 does not change. Only when the third-stage roller distance adjusting assembly 11 works and the slider in the third-stage roller distance adjusting assembly between the third and fourth rollers moves back and forth, the bearing seat of the fourth roller 6 will move up and down, so that the roller distance between the third and fourth rollers can change, completing the roller distance adjustment work between the third and fourth rollers.

[0032] In this embodiment, the first-stage roller distance adjusting assembly 8, the second-stage roller distance adjusting assembly 10, and the third-stage roller distance adjusting assembly 11 all adopt the above-mentioned screw-type adjusting structure design.

[0033] In this embodiment, the pushing roller distance adjusting assembly 12 includes a pushing motor 1201. The pushing motor 1201 is fixedly installed on the outer wall of one side of the top of the frame 2. The output end of the pushing motor 1201 is fixedly connected with a second-stage reduction gearbox 1202. The output end of the second-stage reduction gearbox 1202 is fixedly installed with a second-stage lead screw 1203. A pushing seat 1204 is threaded on the second-stage lead screw 1203;

[0034] In this structural design, when it is necessary to adjust the distance between the fourth roller 6 and the fifth roller 7, the pushing motor 1201 operates. When the pushing motor 1201 operates, it drives the second-stage lead screw 1203 to rotate through the second-stage reduction gearbox 1202. When the second-stage lead screw 1203 rotates, the pushing seat 1204 connected to it by threads will move. When the pushing seat 1204 moves towards the fifth roller 7, it will push the bearing seat of the fifth roller 7, thereby enabling the fifth roller 7 to move towards the fourth roller 6, so as to reduce the distance between the fourth roller 6 and the fifth roller 7 and achieve the purpose of using the roll gap adjustment.

[0035] In this embodiment, in order to enable the roller to perform a certain elastic reset after each roll gap adjustment component is reset, a compression spring 9 is fixedly installed between the bearing seats of the first roller 3 and the second roller 4;

[0036] In this structural design, when the first roller 3 is lifted upward, it will compress the compression spring 9. Thus, when the distance adjustment slider of the first roll gap adjustment component 8 returns and exits, the compressed compression spring 9 performs elastic reset, thereby driving the first roller 3 to move downward, so as to achieve the purpose of distance adjustment reset;

[0037] A pressure regulating spring 13 is installed above the bearing seat of the fourth roller 6. When the fourth roller 6 is lifted upward under the action of the third-stage roll gap adjustment component 11, it will compress the pressure regulating spring 13. When the slider of the third-stage roll gap adjustment component 11 returns and exits, the compressed pressure regulating spring 13 performs elastic reset, thereby driving the fourth roller 6 to move downward to complete the reset effect of the fourth roller 6;

[0038] On both sides of the bearing seat of the fifth roller 7 and on the side far from the pushing roll gap adjustment component 12, a thrust spring 14 is fixedly installed between the fifth roller 7 and the frame 2;

[0039] In this structural design, when the fifth roller 7 moves towards the fourth roller 6 under the action of the pushing roll gap adjustment component 12, it will compress the thrust spring 14, making the thrust spring 14 in a compressed state. When the pushing seat 1204 of the pushing roll gap adjustment component 12 moves backward and resets, the compressed thrust spring 14 resets, thereby driving the fifth roller 7 to move leftward for reset, having a good reset use effect.

[0040] Working principle: Those skilled in the art can use the calender of the present utility model through conventional usage methods;

[0041] The utility model is provided with a plurality of roller distance adjusting components. When it is necessary to adjust the distance between the first roller 3 and the second roller 4, the provided distance adjusting motor 801 can rotate. When the distance adjusting motor 801 rotates, it drives the distance adjusting screw rod 803 to slowly rotate through a primary reduction gearbox 802. Since a distance adjusting slider 804 is threadedly connected to the distance adjusting screw rod 803, when the distance adjusting screw rod 803 rotates, the distance adjusting slider 804 thereon will move to one side. Since the upper surface of the distance adjusting slider 804 is designed with an inclined surface structure, when the distance adjusting slider 804 moves towards the bearing seat side, it will push against the bearing seat through the inclined surface, thereby raising the first roller 3 by pushing against the bearing seat. When the first roller 3 rises and is elevated, the distance between the first roller 3 and the second roller 4 decreases, so as to achieve the use effect of automatically adjusting the roller distance;

[0042] Similarly, when it is necessary to adjust the roller distance between the second roller 4 and the third roller 5, the secondary roller distance adjusting component 10 works, so that the slider of the secondary roller distance adjusting component 10 pushes against the third roller 5 to rise and be elevated. At this time, the distance between the second roller 4 and the third roller 5 increases, achieving the purpose of adjusting the roller distance between the second roller 4 and the third roller 5;

[0043] Since the slider of the tertiary roller distance adjusting component 11 does not displace, when the third roller 5 moves upward, it will simultaneously push the fourth roller 6 and the bearing seat on the fourth roller to move up and down synchronously through the tertiary roller distance adjusting component 11. Since the slider of the distance adjusting mechanism of the fourth roller 6 does not slide back and forth, the roller distance between the third roller 5 and the fourth roller 6 does not change. Only when the tertiary roller distance adjusting component 11 works and the slider in the tertiary roller distance adjusting component between the third and fourth rollers moves back and forth, the bearing seat of the fourth roller 6 will move up and down, so that the roller distance between the third and fourth rollers can change, completing the roller distance adjustment work between the third and fourth rollers;

[0044] When it is necessary to adjust the distance between the fourth roller 6 and the fifth roller 7, the pushing motor 1201 works. When the pushing motor 1201 works, it drives the secondary screw rod 1203 to rotate through a secondary reduction gearbox 1202. When the secondary screw rod 1203 rotates, the pushing seat 1204 threadedly connected thereto will displace. When the pushing seat 1204 moves towards the fifth roller 7 side, it will push against the bearing seat of the fifth roller 7, so that the fifth roller 7 can move towards the fourth roller 6 side, thereby reducing the distance between the fourth roller 6 and the fifth roller 7, achieving the use purpose of roller distance adjustment;

[0045] In order to perform a structural reset on the adjusted roller, the present utility model is provided with different spring structures on the roller. When the first roller 3 is lifted upward, it will compress the pressing spring 9. Thus, when the distance-adjusting slider of the first roller distance adjustment assembly 8 returns and exits, the compressed pressing spring 9 performs elastic reset, thereby driving the first roller 3 to move downward, so as to achieve the purpose of distance adjustment reset;

[0046] Above the bearing seat of the fourth roller 6, a pressure-regulating spring 13 is installed. When the fourth roller 6 is lifted upward under the action of the third roller distance adjustment assembly 11, it will compress the pressure-regulating spring 13. When the slider of the third roller distance adjustment assembly 11 returns and exits, the compressed pressure-regulating spring 13 performs elastic reset, thereby driving the fourth roller 6 to move downward to complete the reset effect of the fourth roller 6;

[0047] On both sides of the bearing seat of the fifth roller 7 and on the side far from the push-type roller distance adjustment assembly 12, a thrust spring 14 is fixedly installed between the fifth roller 7 and the frame 2;

[0048] With this structural design, when the fifth roller 7 moves toward the fourth roller 6 under the action of the push-type roller distance adjustment assembly 12, it will compress the thrust spring 14, making the thrust spring 14 in a compressed state. When the push seat 1204 of the push-type roller distance adjustment assembly 12 moves in the reverse direction and resets, the compressed thrust spring 14 resets, thereby driving the fifth roller 7 to move to the left for reset, having a good reset use effect.

[0049] To sum up, the roller distance adjustment structure of the calender of the present utility model can complete the work of pushing and adjusting the roller distance between rollers through the cooperation of the motor, the lead screw and the slider. Thus, through the motor, the roller distance adjustment process is automated, having the use characteristics of fully automatic roller distance adjustment. Compared with manual adjustment, the present utility model has the technical characteristics of fully automatic roller distance adjustment. At the same time, in the process of the motor driving the slider to move, there are the use characteristics of accurate displacement control and high adjustment accuracy, effectively improving the automatic adjustment effect of the roller distance and increasing the calendering processing quality of the calender;

[0050] Moreover, the roller distance adjustment assemblies between the rollers have good adjustment independence, and can freely adjust the roller distance between two groups of rollers, having the independent and free adjustment effect between several rollers, with good use performance and stronger practicability.

[0051] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model. Any reference signs in the claims should not be construed as limiting the claims involved.
