Specifically, bearings 33 are installed at both axial ends of the shaft 31. The bearing 33 of the shaft 31 located at the bottom is directly interference fit into the support plate 2.

[0032] like Figure 1 As shown, the pressure roller assembly 3 located at the top includes sleeves 34 located at both ends of the shaft 31. The shaft 31 passes through the sleeves 34 and is combined with the Figure 2 The sleeve 34 is a rectangular block structure, the shaft 31 passes through the sleeve 34, and the sleeve 34 and the shaft 31 are connected by a bearing 33. The support plate 2 is provided with a through hole 21, which is a square hole. The through hole 21 passes through the support plate 2 along the axis of the shaft 31. The sleeve 34 is located in the through hole 21. The outer size of the sleeve 34 is smaller than the hole size of the through hole 21. Figure 2 The sleeve 34 can move in the through hole 21 along the left-right direction and the up-down direction.

[0033] Figure 2 In the illustrated orientation, the sleeve 34 includes two opposing walls 345 on the left and right, and one opposing wall 344 on the top and bottom. The support plate 2 is provided with a first insertion hole 22, a second insertion hole 23, and a countersunk hole 24. The second insertion hole 23 is located at the upper end of the support plate 2, and the first insertion hole 22 extends downward from the upper end surface of the support plate 2 to the through-hole 21. The countersunk hole 24 is located at the bottom of the through-hole 21, extending downwardly along the bottom end surface of the through-hole 21. A first pressing component 341 is internally threadedly connected to the second insertion hole 23, and a third pressing component 343 is threadedly connected to the countersunk hole 24. Both the first pressing component 341 and the third pressing component 343 are capable of extending into the through-hole 21 and abutting against the first insertion wall 344. The first insertion hole 22 is located on both sides of the support plate 2, extending through the support plate 2. The second insertion hole 22 is threadedly connected to the second insertion hole 22, and the second pressing component 342 is capable of abutting against the second insertion wall 345.

[0034] Both the first wall 344 and the second wall 345 are installed with pressure pads 4 to facilitate compaction.

[0035] Figure 2 In the position shown, the upper end of the clamping part 343 is exposed from the bottom inner wall of the through hole 21. Since the through hole 21 passes through the support plate 2, the wrench can be inserted into the through hole 21 to screw the clamping part 343. By adjusting the vertical position of the clamping part 343 and the clamping part 1 341 and the horizontal position of the clamping part 2 342, the position of the sleeve 34 can be adjusted. Figure 1, so that the shaft body 31 located above is parallel to the shaft body 31 located below.

[0036] like Figure 1 As shown, the shaft 31 passes through the roller body 32 and the two are fixedly connected. The roller body 32 rotates coaxially with the shaft 31. A gap 102 is formed between the upper and lower roller bodies 32. When the inner spacer 101 passes through the gap 102, it is pressed up and down to form to the desired thickness. When the inner spacer 101 passes through the gap 102, the inner spacer 101 is pulled out and drives the two roller bodies 32 to rotate. The inner spacer 101 is a PFA sheet with a thickness of 1-3 mm.

The sleeve 34 is located between the two limit plates 35, and the end surface of the sleeve 34 abuts against the end surface of the limit plate 35. The limit plate 35 limits the sleeve 34 to prevent the sleeve 34 from moving.

[0038] like Figure 1 As shown, the bottom of the limiting plate 35 is higher than the bottom of the sleeve 34 to prevent the limiting plate 35 from interfering with the wrench extending into the through hole 21 and screwing the clamping component 343 .

[0039] like Figure 3 、 Figure 4 As shown, an adjustment mechanism of a calendering device includes the above-mentioned calendering device and also includes a rod body 2 6. The rod body 2 6 can be moved and placed between the two support plates 2. The bottom surface of the rod body 2 6 abuts against the bottom plate 1. The two ends of the rod body 2 6 in the length direction respectively abut against the support plates 2, and a pin is inserted into the rod body 2 from the support plates 2 along the length direction of the rod body 2 6 to form a limit for the rod body 2 6.

[0040] like Figure 3 As shown, the upper end of the rod body 6 is provided with a slide groove 61, combined with Figure 4 、 Figure 5 ,in Figure 5 for Figure 4 In the P-direction view, a slide rod 9 is slidably connected in the slide groove 61, and the rod 9 can move between the two support plates 2 along the length direction of the rod body 2 6.

[0041] like Figure 3 As shown, the slide bar 9 is installed with a slider 2 7 , and a slide groove 2 91 is provided in the up and down directions of the slide bar 9 , and the slider 2 7 can move up and down along the slide groove 2 91 .

[0042] like Figure 5As shown, the slide bar 9 is provided with a third slide groove 92, which is located on both sides of the second slide groove 91 and extends through the inner wall of the slide bar 9. The slider 7 is threadedly connected to a second gauge 8, which is a conventional micrometer. The gauge 8 includes a second probe 81 near the side of the roller body 32. The probe 81 can be extended and retracted, and the pointer on the gauge 8 rotates when the probe 81 is extended and retracted. The gauge 8 passes through the third slide groove 92, and the probe 81 can abut the outer wall of the roller body 32.

[0043] like Figure 1 As shown, the support plate 2 is provided with a boss 25, which is located between the two support plates 2. The boss 25 extends along the end surface of one side support plate 2 toward the other side support plate 2 to form a bulge. The upper ends of the bosses 25 on both sides are slidably connected to the rod body 5, and the two ends of the rod body 5 in the length direction abut against the support plate 2. Figure 1 In the azimuth, the rod body 15 can slide back and forth.

[0044] like Figure 1 As shown, the rod body 15 is slidably connected to a slider 151, and the slider 151 can move along the length direction of the rod body 15 (i.e. Figure 1 The slider 51 is provided with a meter 52 which is also a micrometer. The meter 52 includes a probe 521 at the bottom. The probe 521 can abut against the outer wall of the top of the pressure roller body 32.

[0045] The adjustment method of the adjustment mechanism of the above-mentioned calendering device is as follows:

[0046] Alignment adjustment:

[0047] ① Such as Figure 2 As shown, the pressing component 1 341 and the pressing component 2 342 are loosened, and the pressing component 1 341 and the pressing component 2 342 are separated from the sleeve 34, and the bottom of the sleeve 34 abuts against the upper end of the pressing component 343, so that the sleeve 34 can move and adjust the position of the sleeve 34;

[0048] ② Install the second rod 6 between the two support plates 2, and move the second meter 8 up and down so that the second probe 81 of the meter 8 respectively contacts the upper and lower roller bodies 32, and record the readings of the meter 8 at the two contacts;

[0049] ③ By moving the sliding rod 9, the meter 2 8 is moved along the axis of the shaft 31 for a distance, and the meter 2 8 is moved up and down again so that the probe 2 81 abuts against the upper and lower roller bodies 32 respectively, and the method of determining a straight line by two points is used to determine whether the axes of the two roller bodies 32 are in the same plane. Figure 2As shown in the direction, by moving the sleeve 34 left and right, the two pressure roller bodies 32 are aligned up and down, so that the two pressure roller bodies 32 are installed relative to each other up and down and form a gap portion 102; by adjusting the position of the pressure roller body 32 located above, the two pressure roller bodies 32 can be aligned up and down during installation to offset the precision errors generated during processing and installation.

[0050] ④ Fix the sleeve 34 by pressing component 1 341 , pressing component 2 342 , and pressing component 3 343 .

[0051] Individual adjustment of the upper axis:

[0052] like Figure 1 As shown, the meter 1 52 is moved left and right, and the probe 1 521 of the meter 1 52 abuts against the upper end of the roller body 32 located above to measure the inclination of the roller body 32. The inclination is adjusted by adjusting the height of the sleeves 34 on both sides, so that the gap 102 can be of the same height up and down to form the inner spacer 101 with a uniform thickness. The inner spacer 101 with a certain inclination can also be formed by adjusting the inclination angle. Figure 6 As shown, in the actual application of the inner partition 101, the inner wall surface 1001 of the container body 100 is inclined to form a bell mouth, and the inner partition 101 is attached to the inner wall surface 1001. By forming the inner partition 101 with an inclination, the inner partition 101 is matched with the inclined inner wall surface 1001. When the corrosive solvent is injected into the container body 100, the solvent pressure makes the inner partition 101 adhere more closely to the inner wall surface 1001. At the same time, the inner wall surface 1001 limits the inner partition 101 to prevent the inner partition 101 from floating up, thereby improving the adhesion between the inner partition 101 and the inner wall surface 1001 and better protecting the inner wall surface 1001 from erosion by the corrosive solvent.
