Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Please see Figures 1-9 This utility model provides an embodiment: a high-efficiency PVC resin kneading machine, including a side plate 1, a flattening mechanism 2 and a winding adjustment mechanism 3. Support rods 11 are welded to the bottom of the side plate 1, and the number of support rods 11 is three. The flattening mechanism 2 is fixedly connected to the top of the side plate 1, and the winding adjustment mechanism 3 is fixedly connected to the bottom of the side plate 1.

[0027] The flattening mechanism 2 includes a support base 21, a support block 22, a pneumatic lifter 23, a slider 24, and a first roller 25. The support base 21 is fixedly connected to the side plate 1 by a first bolt 201. The top of the support base 21 is fixedly connected to the support block 22 by a second bolt 202. A slide rail 211 is provided on one side of the support base 21, and the slide rail 211 is slidably connected to the slider 24. One end of the slide rod 231 is fixedly connected to the top of the slider 24, and the other end of the slide rod 231 is slidably connected to the pneumatic lifter 23. The bottom of the slider 24 is fixedly connected to the first roller 25 by a third bolt 203. The height of the first roller 25 is automatically adjusted by the pneumatic lifter 23, which improves the efficiency of the debugging work.

[0028] In this embodiment, firstly, the support base 21 is fixedly installed to the side plate 1 by the first bolt 201, and the first roller shaft 25 is fixedly connected to the slider 24 by the third bolt 203. Then, the slider 24 with the first roller shaft 25 is placed on the slide rail 211. After that, the support block is fixedly installed to the support base 21 by the second bolt 202. Then, the pneumatic lifter 23 is installed on the support block 22 and fixedly installed to the slider 24 by the slide rod 231.

[0029] When the first roller shaft 25 needs to be raised, the pneumatic lifter 23 is activated, driving the slide bar 231 to move upward, which in turn moves the slider 24 in the slide rail 211, thereby causing the first roller shaft 25 to move upward. When the first roller shaft 25 needs to be lowered, the pneumatic lifter 23 is activated, driving the slide bar 231 to move upward, which in turn moves the slider 24 in the slide rail 211, thereby causing the first roller shaft 25 to move downward.

[0030] The bottom of the first roller shaft 25 is provided with a second roller shaft 4. The two ends of the second roller shaft 4 are fixedly connected to the side plates 1. A third roller shaft 5 and a fixing rod 51 are provided between the flattening mechanism 2 and the winding adjustment mechanism 3. The fixing rod 51 is located on the top of the third roller shaft 5. The two ends of the third roller shaft 5 and the fixing rod 51 are fixedly connected to the side plates 1 respectively, so that the PVC film 7 is conveyed and buffered to be straightened, which facilitates the winding of the PVC film 7.

[0031] In this embodiment, when the PVC film 7 is output from between the first roller 25 and the second roller 4, it passes over the second roller 4, then passes under the third roller 5, and then is output from the fixed rod 51.

[0032] The winding adjustment mechanism 3 includes a lead screw 31, a moving block 32, a track 33, and a fixed block 34. Both ends of the lead screw 31 are connected to one end of the fixed block 34 via bearings 301. The other end of the fixed block 34 is fixedly connected to the side plate 1. The lead screw 31 is slidably connected to the moving block 32. The moving block 32 has a groove 321, which is slidably connected to the track 33. Through the winding adjustment mechanism 3, the position of the PVC film 7 collection shaft is determined, which further improves the efficiency of the debugging work.

[0033] One end of the movable block 32 is fixedly connected to one end of the first fixed rod 322. The other end of the first fixed rod 322 is hinged to the connecting rod 324 via a positioning pin 323. One end of the connecting rod 324 is fixedly connected to one end of the second fixed rod 325. The other end of the second fixed rod 325 is slidably connected to one end of the movable block 326. A spring 327 is provided between the movable block 326 and the second fixed rod 325. The first fixed rod 322 has several position holes 3221. The other end of the movable block 326 has a round block 3261. The round block 3261 engages with the position holes 3221. By adjusting the connecting rod 324, it can be adapted to collection shafts of different sizes, thereby reducing design and manufacturing costs.

[0034] The other end of the connecting rod 324 is provided with a fourth roller 6, and the side plate 1 is provided with slots 12. The slots 12 are fixedly connected to the fourth roller 6 to realize the collection and roll formation of PVC film 7.

[0035] In this embodiment, when the position of the collection shaft of the PVC membrane 7 needs to be adjusted, the moving block 32 moves, which drives the lead screw 31 to rotate, thereby reaching the required position.

[0036] When the PVC film 7 needs to be adjusted to collect shafts of different sizes, firstly, the movable block 326 is moved outward so that the round block 3261 disengages from the position hole 3221, causing the spring 327 to retract. Then, the height of the second fixing rod 325 is adjusted so that the front rod of the first fixing rod 322 moves up and down. When it is adjusted to the appropriate position, the round block 3261 of the movable block 326 is aligned with the position hole 3221 and fixed by the supporting force of the spring 327.

[0037] Working principle: When the first roller shaft 25 needs to be raised, the pneumatic lifter 23 is activated, driving the slide bar 231 to move upward, which in turn moves the slider 24 in the slide rail 211, thus causing the first roller shaft 25 to move upward. When the first roller shaft 25 needs to be lowered, the pneumatic lifter 23 is activated, driving the slide bar 231 to move upward, which in turn moves the slider 24 in the slide rail 211, thus causing the first roller shaft 25 to move downward. When the PVC film 7 needs to adjust the position of the collection shaft, the moving block 32 moves, which drives the lead screw 31 to rotate, thus reaching the required position.

[0038] When the position of the collection shaft of the PVC membrane 7 needs to be adjusted, the moving block 32 moves, driving the lead screw 31 to rotate, thereby reaching the required position;

[0039] When the PVC film 7 needs to be adjusted to collect shafts of different sizes, the movable block 326 is moved outward, so that the round block 3261 disengages from the position hole 3221, and the spring 327 retracts. Then, the height of the second fixing rod 325 is adjusted, so that the front rod of the first fixing rod 322 moves up and down. When it is adjusted to a suitable position, the round block 3261 of the movable block 326 is aligned with the position hole 3221 and fixed by the supporting force of the spring 327.
