DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-Figure 14 , a TPU calendering film processing device that is easy to disassemble, comprising a pressing roller 1 and a workbench 2, and also comprising: A spacing adjustment component, the spacing adjustment component includes a pillar 3, a top plate 4, a cover body 5, a motor 6, a worm wheel 7, a worm 8, a positive and negative threaded screw 9 and a lifting plate 10. The pillars 3 are arranged at the four corners above the workbench 2, the top plates 4 are arranged above four groups of the pillars 3, the cover body 5 is arranged on the top plate 4, a worm 8 and two groups of worm wheels 7 are arranged in the cover body 5, the output end of the motor 6 passes through the cover body 5 and is connected to the worm 8, the worm 8 is meshed with the two groups of worm wheels 7, the positive and negative threaded screw 9 is rotatably connected to the workbench 2 at the bottom, the positive and negative threaded screw 9 passes through the top plate 4 and the cover body 5 at the top and is connected to the center of the worm wheel 7, the lifting plates 10 are arranged in two groups arranged up and down, and screw holes threadedly connected to the positive and negative threaded screws 9 are arranged on the left and right sides of the two groups of lifting plates 10; When it is necessary to adjust the spacing between the two groups of rollers 1, turn on the motor 6 (using a servo motor 6, the rotation speed and rotation angle can be precisely controlled). The output end of the motor 6 drives the worm 8 to rotate. Since the worm 8 is meshed with the two groups of worm wheels 7, the rotation of the worm 8 will drive the two groups of worm wheels 7 to rotate synchronously. The worm wheel 7 is centrally connected to the positive and negative threaded screw 9, and the rotation of the worm wheel 7 in turn drives the positive and negative threaded screw 9 to rotate. The left and right sides of the two groups of lifting plates 10 are provided with screw holes threadedly connected to the positive and negative threaded screw 9. When the positive and negative threaded screw 9 rotates, according to the principle of thread transmission, the two groups of lifting plates 10 will move up and down along the positive and negative threaded screw 9. Due to the characteristics of the positive and negative threaded screw 9, the two groups of lifting plates 10 will move up or down at the same time, thereby realizing the rapid adjustment of the spacing between the two groups of rollers 1. The four corners of the lifting plates 10 are provided with lifting holes slidably connected to the pillars 3, further ensuring the stability of the lifting of the two groups of lifting plates 10; The centers of the two groups of lifting plates 10 are both provided with hollow holes, and the lifting plates 10 are provided with bearing members for bearing the pressing rollers 1, and the bearing members stably bear the two groups of pressing rollers 1. When the interval between the two groups of lifting plates 10 becomes smaller, the pressing roller 1 located on the upper side can pass through the lifting plates 10 located on the upper side and contact with the top wall of the pressing roller 1 located on the lower side for rolling.

[0018] In this embodiment, the bearing member includes a mounting seat 11, a support block 12, a bearing 13, a spline 14 and a reset member. The mounting seat 11 is T-shaped, and the lower part of the middle part of the mounting seat 11 is slidably connected to the hollow hole. A support block 12 is arranged above the mounting seat 11 at one end away from the center of the workbench 2, and a bearing 13 is embedded in the support block 12. The inner ring of the bearing 13 is provided with the spline 14. Connecting columns 15 are symmetrically arranged on the left and right sides of the pressure roller 1, and key grooves adapted to the spline 14 are arranged on the connecting columns 15. A reset member is also arranged on the mounting seat 11, and a limit block 16 for limiting the mounting seat 11 is also arranged on the two groups of pillars 3 on the same side. The mounting seat 11 of the bearing member is T-shaped. The lower part of the middle part is slidably connected with the hollow hole of the lifting plate 10, and the upper support block 12 away from the center of the workbench 2 is embedded with a bearing 13. The spline 14 of the inner ring of the bearing 13 cooperates with the keyway on the connecting column 15 of the pressure roller 1 to achieve stable bearing of the pressure roller 1. When the pressure roller 1 is disassembled, the distance between the two groups of lifting plates 10 is increased through the spacing adjustment component. The reset member includes a first spring 17, a first guide rod 18 and a moving block 19. The first guide rod 18 is arranged in two groups symmetrically front and back. The two ends of the first guide rod 18 are respectively connected to the moving block 19 and the mounting seat 11. The first guide rod 18 passes through the lifting plate 10. The lifting plate 10 is also provided with a notch on the left and right sides thereof that matches the moving block 19. The first spring 17 is sleeved on the first guide rod 18. The first The two ends of the spring 17 are connected to the lifting plate 10 and the mounting seat 11 respectively. The moving block 19 is provided with an inclined surface 25 on the side close to the mounting seat 11. The limit block 16 is in an inverted T shape. At this time, the reset member (composed of the first spring 17, the first guide rod 18 and the moving block 19) is misaligned with the limit block 16. The elastic force of the first spring 17 pulls the mounting seat 11 to move, so that the distance between the two groups of mounting seats 11 becomes larger, and the spline 14 exits the keyway. In this way, there is enough space in the upper part and the left and right sides of the two groups of pressure rollers 1, which is convenient for disassembling the pressure rollers 1. During installation, the operation is reversed, the connecting column 15 of the pressure roller 1 is aligned with the spline 14 and inserted, and the mounting seat 11 is returned to the initial position by the elastic force of the reset member, so that the pressure roller 1 is installed.

[0019] In actual use, when the spline 14 is assembled with the keyway, it is necessary to stably align the spline 14 and the keyway. For this purpose, the spline 14 protrudes from the bearing 13, and a chamfer 26 is provided at one end of the spline 14 away from the support block 12. An auxiliary frame 20 is also provided above the other end of the mounting seat 11. The auxiliary frame 20 is provided with two groups of front-to-back symmetrical arrangements, and auxiliary rollers 21 are rotatably provided on the auxiliary frame 20. The outer walls of the two groups of auxiliary rollers 21 fit the connecting column 15 to ensure that the inner ring of the bearing 13 and the connecting column 15 are in the same horizontal plane. When the spline 14 is stably assembled after inspection, there is still a gap between the mounting seat 11 and the pressure roller 1.

[0020] During the plugging process of the connecting column 15 and the spline 14, it is also necessary to ensure that the keyway is aligned with the spline 14. For this purpose, the mounting seat 11 is also provided with a positioning member for positioning the spline 14 and the keyway, and the positioning member includes a second guide rod 22, a second spring 23, an adjustment plate 24, an elastic member, an adjustment block 27 and a positioning block 28. The mounting seat 11 is provided with an adjustment groove at one end away from the support block 12, and the front and rear side walls of the adjustment plate 24 are in contact with the adjustment groove. The adjustment plate 24 is also provided with a second guide rod 22 that passes through the mounting seat 11, and a second spring 23 is sleeved on the second guide rod 22. The upper and lower ends of the second spring 23 are respectively in contact with the top wall and the lower wall of the adjustment groove. The adjusting plate 24 is connected, and two groups of symmetrically arranged elastic members are also provided on the adjusting plate 24. An inverted T-shaped adjusting block 27 is also provided above the elastic member. The middle part of the adjusting block 27 passes through the mounting seat 11. The middle part of the adjusting block 27 is arranged between the two groups of the auxiliary frames 20. One end of the adjusting block 27 is provided with a groove adapted to the protruding part of the spline 14. A positioning block 28 is also provided above the other end of the adjusting block 27. A positioning groove adapted to the positioning block 28 is also provided in the keyway. A step block passing through the adjusting groove is also provided on the lifting plate 10. The step block includes a positioning area 31, a transition area 32 and a release area 33. The transition zone 32 is inclined, and the upper and lower sides of the transition zone 32 are respectively connected to the positioning zone 31 and the release zone 33. The release zone 33 is arranged near one end of the pressure roller 1. Initially, when the distance between the two sets of mounting seats 11 is large, the second spring 23 is in a compressed state, and the adjustment plate 24 is held in a higher position by the positioning zone 31. When the pressure roller 1 with the connecting column 15 is assembled, the connecting column 15 is placed on the corresponding two sets of auxiliary rollers 21. If the positioning groove is not aligned with the positioning block 28, the elastic member contracts at this time, and the pressure roller 1 with the connecting column 15 can be rotated until the keyway and the positioning groove are aligned with the positioning block 28. At this time, the pressure roller 1 is no longer rotated, and the bearing is rotated through the protruding spline 14. 13, until the spline 14 is aligned with the groove and the elastic member is reset. At this time, the bearing 13 and the pressure roller 1 with the connecting column 15 can no longer rotate. As the distance between the two sets of lifting plates 10 becomes smaller, the corresponding moving block 19 contacts the limit block 16, and the moving block 19 pushes the first guide rod 18, thereby the first spring 17 extends, and the mounting seat 11 moves toward the position of the pressure roller 1. At this time, the adjustment plate 24 descends from the positioning area 31 to the transition area 32 and then to the release area 33, and the second spring 23 naturally extends. At this time, the elastic member naturally extends, and the limit block 16 and the groove of the adjustment block 27 are respectively misaligned with the connecting column 15 and the spline 14, which does not affect the natural rotation of the pressure roller 1 and ensures the stability of the assembly of the pressure roller 1.

[0021] In this embodiment, the elastic member includes a third spring 29 and a telescopic rod 30. The third spring 29 is sleeved on the telescopic rod 30. The upper and lower ends of the third spring 29 and the telescopic rod 30 are respectively connected to the adjustment block 27 and the adjustment plate 24. The third spring 29 is naturally extended to facilitate the adjustment block 27 to be in a higher position. The telescopic rod 30 ensures the stability of the movement of the adjustment block 27.

[0022] It should be noted that the upper portion of the limit block 16 is shorter than the lower portion of the limit block 16 , and the upper and lower contact portions of the two groups of rollers 1 are located above the middle portion of the reverse thread of the forward and reverse thread screws 9 .
