DETAILED DESCRIPTION

[0030] The utility model is further described in conjunction with the following embodiments.

[0031] Depend on Figures 1 to 9 It can be seen that the liquid silicone composite film calender described in this embodiment includes a discharge platform 11 and a calendering roller 12; the discharge platform 11 is provided with a fixed seat 2; the fixed seat 2 is provided with a sliding seat 3 for lifting and lowering along the height direction; the calendering roller 12 is rotatably provided on the sliding seat 3; the fixed seat 2 is provided with a screw 4 for rotating along the height direction; the outer sleeve of the screw 4 is provided with a nut 5;

[0032] The nut 5 includes an upper platform 51, a limiting portion 52 and a lower platform 53 arranged in sequence along the height direction; the limiting portion 52 is threadedly connected to the screw rod 4; the sliding seat 3 is provided with a boss 31; the boss 31 is slidably sleeved outside the limiting portion 52 along the height direction; the boss 31 is surface-connected with the limiting portion 52; the upper platform 51 and the lower platform 53 are used to abut against the top and bottom of the boss 31 respectively.

[0033] Specifically, in the liquid silicone composite film calendering machine described in this embodiment, when it is necessary to adjust the height of the calendering roller 12, the screw 4 can be rotated by an external motor. Since the limiting portion 52 of the nut 5 is connected to the profile of the boss 31 of the sliding seat 3, that is, the limiting portion 52 and the boss 31 cannot rotate relative to each other, and since the sliding seat 3 is restricted on the fixed seat 2 for lifting and lowering activities, the nut 5 can be lifted and lowered during the rotation of the screw 4. Since the height of the limiting portion 52 is higher than the height of the boss 31, that is, when the screw 4 just rotates, the boss 31 can be lifted and lowered at the limiting portion 52, and the boss 31 and the limiting portion 52 are relatively displaced in the height direction until the upper platform 51 abuts against the top of the boss 31, or the lower platform 53 abuts against the bottom of the boss 31, the screw 4 is continued to be rotated, and the nut 5 can drive the sliding seat 3 to lift and lower on the fixed seat 2, thereby adjusting the distance between the calendering roller 12 and the discharge platform 11.

[0034] In this embodiment, after adjusting the height of the sliding seat 3 and the calendering roller 12, the limiting portion 52 of the nut 5 and the boss 31 of the sliding seat 3 are in a sliding state, and the sliding seat 3 does not transfer stress to the nut 5 and the screw 4, thereby extending the service life of the nut 5 and the screw 4.

[0035] In the liquid silicone composite film calender described in this embodiment, the fixed seat 2 is provided with slide rails 21 on both sides, and the sliding seat 3 is provided with sliders 32 matching with the slide rails 21 on both sides. Specifically, the above arrangement plays a guiding role in the lifting and lowering of the sliding seat 3.

[0036] In the liquid silicone composite film calender described in this embodiment, the slider 32 is provided with a friction block 33. Specifically, through the above arrangement, the friction between the sliding seat 3 and the fixed seat 2 can be enhanced, so that the sliding seat 3 can be kept in the current position in a natural state.

[0037] In the liquid silicone composite film calender described in this embodiment, the fixing seat 2 is provided with a limiting passage 22 along the height direction; the boss 31 is arranged through the limiting passage 22.

Specifically, through the above arrangement, in the natural state, the locking protrusion 23 is locked with the locking groove 65, so that the sliding seat 3 can be kept in the position of the fixed seat 2.

[0039] In the liquid silicone composite film calender described in this embodiment, the side walls on both sides of the limiting channel 22 are provided with a plurality of locking protrusions 23 along the height direction; the side walls on both sides of the boss 31 are provided with a first fixing block 61 and a second fixing block 63 respectively in a movable and retractable manner along the width direction. Specifically, the above arrangement can further ensure the stability of the connection between the sliding seat 3 and the fixed seat 2.

[0040] In the liquid silicone composite film calender described in this embodiment, a return spring 66 is provided at one end where the first fixed block 61 and the second fixed block 63 are close to each other; a driving plate 7 is provided on the boss 31 for lifting and lowering movement along the height direction; the driving plate 7 is used to drive the first fixed block 61 and the second fixed block 63 to perform telescopic movement; the top of the driving plate 7 is used to abut against the upper platform 51; the bottom of the driving plate 7 is used to abut against the lower platform 53. In the liquid silicone composite film calender described in this embodiment, the driving plate 7 is provided with a first limit groove; the first fixed block 61 is provided with a first limit pin 62 for moving in the first limit groove; the first limit groove includes a first upper inclined groove 81, a first vertical groove 82 and a first lower inclined groove 83; the first upper inclined groove 81 is arranged at the top of the first vertical groove 82; the first lower inclined groove 83 is arranged at the bottom of the first vertical groove 82; the first upper inclined groove 81 and the first lower inclined groove 83 are both inclined in the direction of the second fixed block 63; when the first limit pin 62 moves to the top of the first upper inclined groove 81, the top of the boss 31 abuts against the upper platform 51; when the first limit pin 62 moves to the bottom of the first lower inclined groove 83, the bottom of the boss 31 abuts against the lower platform 53. In the liquid silicone composite film calender described in this embodiment, the driving plate 7 is provided with a second limit groove; the second fixed block 63 is provided with a second limit pin 64 for moving in the second limit groove; the second limit groove includes a second upper inclined groove 91, a second vertical groove 92 and a second lower inclined groove 93; the second upper inclined groove 91 is arranged at the top of the second vertical groove 92; the second lower inclined groove 93 is arranged at the bottom of the second vertical groove 92; the second upper inclined groove 91 and the second lower inclined groove 93 are both inclined in the direction of the first fixed block 61; when the second limit pin 64 moves to the top of the second upper inclined groove 91, the top of the boss 31 abuts against the upper platform 51; when the second limit pin 64 moves to the bottom of the second lower inclined groove 93, the bottom of the boss 31 abuts against the lower platform 53.

[0041] Specifically, the liquid silica composite membrane calender described in this embodiment, under natural conditions, Figure 3 , Figure 4 and Figure 6 As shown, at this time, due to the action of the return spring 66, the first limit pin 62 moves to the position of the first vertical groove 82 and the first fixed block 61 protrudes out of one side of the boss 31, the second limit pin 64 moves to the position of the second vertical groove 92 and the second fixed block 63 protrudes out of the other side of the boss 31, and at this time, the locking groove 65 is locked with the locking protrusions 23 on both sides of the limit channel 22, thereby ensuring that the limit seat can remain fixed in the position of the fixed seat 2.

[0042] When it is necessary to lower the height of the sliding seat 3 and the calendering roller 12, the screw rod 4 is rotated clockwise so that the nut 5 moves downward first, and the upper platform 51 first abuts against the top of the driving plate 7, and presses the driving plate 7 to move downward in the boss 31. During the movement of the driving plate 7, the first limit pin 62 moves along the first upper inclined groove 81, the second limit pin 64 moves along the second upper inclined groove 91, and the first fixed block 61 and the second fixed block 63 compress the reset spring 66 until the first limit pin 62 moves to the top of the first upper inclined groove 81 and the second limit pin 64 moves to the top of the second upper inclined groove 91; the first fixed block 61 retracts to one side of the boss 31, the second fixed block 63 retracts to the other side of the boss 31, and at this time the top of the boss 31 abuts against the upper platform 51; at this time, the screw rod 4 continues to be rotated clockwise, that is, the sliding seat 3 can be driven to descend by the nut 5 to adjust the height of the sliding seat 3 and the calendering roller 12.

[0043] When the height of the sliding seat 3 and the calendering roller 12 is adjusted, the screw 4 is rotated counterclockwise for a certain number of turns to release the upper platform 51 from the driving plate 7. Due to the reset action of the reset spring 66, the first limit pin 62 moves along the inclined surface of the first upper inclined groove 81 to the position of the first vertical groove 82, and the second limit pin 64 moves along the inclined surface of the second upper inclined groove 91 to the position of the second vertical groove 92, so that the first fixed block 61 and the second fixed block 63 are re-extended and locked with the locking protrusion 23 to ensure that the limit seat can remain fixed at the position of the fixed seat 2.

[0044] Since the structure of the first upper inclined groove 81 is the same as that of the first lower inclined groove 83, the structure of the second upper inclined groove 91 is the same as that of the second lower inclined groove 93, and the structure of the upper platform 51 is the same as that of the lower platform 53, that is, the working principle of the sliding seat 3 when it rises is the same as that when the sliding seat 3 descends, and it is only necessary to rotate the screw 4 in the opposite direction.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
