[0034] The calendering cooling assembly includes a fixed frame 5, in which a first rotating shaft 21 and a second rotating shaft 24 are rotatably arranged, and a first rotating roller 12 and a second rotating roller 13 are correspondingly fixedly sleeved on the circumferential surfaces of the first rotating shaft 21 and the second rotating shaft 24, and the second rotating roller 13 is located above the first rotating roller 12.

[0035] The fixing frame 5 is provided with an adjusting mechanism for adjusting the vertical distance between the first rotating roller 12 and the second rotating roller 13 .

[0036] The adjustment mechanism includes an electric push rod 4, first slide grooves 10 are provided on both sides of the fixing frame 5, first sliders 11 are slidably arranged in the first slide grooves 10, and two ends of the second rotating shaft 24 are rotatably connected to a first slider 11. The electric push rod 4 is located at the top of the fixing frame 5, and the telescopic end of the electric push rod 4 passes through the top of the fixing frame 5 and is fixedly connected to one of the first sliders 11.

[0037] When the electric push rod 4 is started, the telescopic end of the electric push rod 4 will drive the first slider 11 to move along the direction of the first slide groove 10, thereby driving the second rotating shaft 24 and the second rotating roller 13 to move as a whole, thereby adjusting the vertical distance between the first rotating roller 12 and the second rotating roller 13.

[0038] The fixed frame 5 is provided with a driving mechanism for driving the first rotating roller 12 and the second rotating roller 13 to rotate synchronously.

[0039] The driving mechanism includes a spring 31. A second motor 9 is fixedly arranged on one side of the fixing frame 5. The output end of the second motor 9 penetrates the fixing frame 5 and is fixedly connected to the first rotating shaft 21. One end of the first rotating shaft 21 away from the second motor 9 extends to the outside of the fixing frame 5. The first gear 22 is fixedly sleeved on the outer end of the first rotating shaft 21. A third rotating shaft 29 is rotatably arranged on one side of the fixing frame 5. A second gear 27 and a second driving wheel 26 are fixedly sleeved on the circumferential surface of the third rotating shaft 29. The second gear 27 is meshed with the first gear 22.

[0040] The fixing frame 5 is provided with a second slide groove 33 on a side away from the second motor 9, and a second slider 34 is slidably arranged in the second slide groove 33. One end of the spring 31 is fixedly connected to one end of the second slider 34 close to the electric push rod 4, and the other end of the spring 31 is fixedly connected to the inner wall of the second slide groove 33 close to the electric push rod 4.

A third belt 23 is transmitted and sleeved between the second driving wheel 26, the third driven wheel 25 and the tensioning wheel 32.

[0041] When the telescopic end of the electric push rod 4 drives the first slider 11 to slide upward, the third driven wheel 25 will also move upward, thereby driving the second slider 34 to slide in the second slide groove 33 toward the electric push rod 4 through the third belt 23. The spring 31 will be gradually compressed during the sliding process of the second slider 34.

[0042] When the telescopic end of the electric push rod 4 drives the first slider 11 to slide downward, the third driven wheel 25 also moves downward, and the third belt 23 begins to relax when the third driven wheel 25 slides downward. At this time, the spring 31 pushes the second slider 34 to slide in the second slide slot 33 in a direction away from the electric push rod 4. The sliding of the second slider 34 drives the first connecting shaft 30 to slide synchronously, and the first connecting shaft 30 drives the tensioning wheel 32 to slide synchronously. The tensioning wheel 32 rolls against the third belt 23 to keep the third belt 23 in a tensioned state.

[0043] After the adjustment is completed, the second motor 9 is started. The second motor 9 drives the first rotating shaft 21 to rotate, and the rotation of the first rotating shaft 21 drives the first rotating roller 12 and the first gear 22 to rotate. The first gear 22 drives the second gear 27 to rotate, and the second gear 27 drives the third rotating shaft 29 to rotate, and the third rotating shaft 29 drives the second driving wheel 26 to rotate. Then, the third driven wheel 25 rotates synchronously under the action of the second driving wheel 26, the tensioning wheel 32 and the third belt 23. The rotation of the third driven wheel 25 drives the second rotating shaft 24 to rotate, thereby driving the second rotating roller 13 and the first rotating roller 12 to rotate synchronously, completing the calendering process of the plastic floor.

[0044] The fan blades 36 are rotatably arranged in the fixing frame 5 along the vertical direction. The gearbox 19 is fixedly arranged on the fixing frame 5 . The driving mechanism is in transmission cooperation with the fan blades 36 through the gearbox 19 .

[0045] The third driving wheel 28 is fixedly sleeved on the outermost side of the third rotating shaft 29 , the first driven wheel 14 is fixedly sleeved on the input end of the gearbox 19 , the first driving wheel 15 is fixedly sleeved on the output end of the gearbox 19 , and a second belt 20 is transmission sleeved between the third driving wheel 28 and the first driven wheel 14 .

[0046] A worm 18 is rotatably arranged in the fixing frame 5, and one end of the worm 18 near the gearbox 19 passes through the fixing frame 5 and extends to the outside. A second driven wheel 17 is fixedly sleeved on the outer end of the worm 18, and a first belt 16 is transmitted between the first driving wheel 15 and the second driven wheel 17.

[0047] Two fourth rotating shafts 37 are rotatably arranged on the top inner wall of the fixing frame 5, and the fan blades 36 are located at the bottom of the fourth rotating shafts 37. A worm wheel 35 is fixedly sleeved on the circumferential surface of each fourth rotating shaft 37, and the worm wheel 35 is meshed with the worm 18.

[0048] When the third rotating shaft 29 rotates, the third driving wheel 28 will also be driven to rotate. The first driven wheel 14 will rotate under the action of the third driving wheel 28 and the second belt 20, thereby causing the input shaft on the gearbox 19 to rotate, thereby causing the output shaft on the gearbox 19 to rotate, thereby causing the first driving wheel 15 to rotate. Under the action of the first driving wheel 15 and the first belt 16, the second driven wheel 17 will rotate, thereby causing the worm 18 to rotate, and the rotation of the worm 18 drives the worm wheel 35 to rotate. Then, the fourth rotating shaft 37 will rotate, thereby driving the fan blades 36 to rotate, thereby cooling the calendered plastic floor.

[0049] The winding assembly includes a winding roller 6, two second fixing seats 7 are fixedly arranged on the top of the bottom plate 1, the winding roller 6 is arranged between the two second fixing seats 7, and both ends of the winding roller 6 are rotatably connected to the two second fixing seats 7. A first motor 8 is fixedly arranged on one side of one of the second fixing seats 7, and the output end of the first motor 8 is fixedly connected to the winding roller 6.

[0050] The first motor 8 is started, and the first motor 8 drives the winding roller 6 to rotate, so as to collect the processed plastic floor.

[0051] How it works

[0052] First, the plastic floor is placed on the placing roller 2 , and the plastic floor on the placing roller 2 is pulled to pass through the first rotating roller 12 and the second rotating roller 13 , and finally rolled up on the winding roller 6 .

[0053] When the electric push rod 4 is started, the telescopic end of the electric push rod 4 will drive the first slider 11 to move along the direction of the first slide groove 10, thereby driving the second rotating shaft 24 and the second rotating roller 13 to move as a whole, thereby adjusting the vertical distance between the first rotating roller 12 and the second rotating roller 13.

[0054] When the telescopic end of the electric push rod 4 drives the first slider 11 to slide upward, the third driven wheel 25 will also move upward, thereby driving the second slider 34 to slide in the second slide groove 33 toward the electric push rod 4 through the third belt 23. The spring 31 will be gradually compressed during the sliding process of the second slider 34.

[0055] When the telescopic end of the electric push rod 4 drives the first slider 11 to slide downward, the third driven wheel 25 also moves downward, and the third belt 23 begins to relax when the third driven wheel 25 slides downward. At this time, the spring 31 pushes the second slider 34 to slide in the second slide slot 33 in a direction away from the electric push rod 4. The sliding of the second slider 34 drives the first connecting shaft 30 to slide synchronously, and the first connecting shaft 30 drives the tensioning wheel 32 to slide synchronously. The tensioning wheel 32 rolls against the third belt 23 to keep the third belt 23 in a tensioned state.

[0056] After the adjustment is completed, the second motor 9 is started. The second motor 9 drives the first rotating shaft 21 to rotate, and the rotation of the first rotating shaft 21 drives the first rotating roller 12 and the first gear 22 to rotate. The first gear 22 drives the second gear 27 to rotate, and the second gear 27 drives the third rotating shaft 29 to rotate, and the third rotating shaft 29 drives the second driving wheel 26 to rotate. Then, the third driven wheel 25 rotates synchronously under the action of the second driving wheel 26, the tensioning wheel 32 and the third belt 23. The rotation of the third driven wheel 25 drives the second rotating shaft 24 to rotate, thereby driving the second rotating roller 13 and the first rotating roller 12 to rotate synchronously, completing the calendering process of the plastic floor.

[0057] Moreover, when the third rotating shaft 29 rotates, the third driving wheel 28 will also be driven to rotate. The first driven wheel 14 will rotate under the action of the third driving wheel 28 and the second belt 20, thereby rotating the input shaft on the gearbox 19, thereby rotating the output shaft on the gearbox 19, and then rotating the first driving wheel 15.

[0058] Under the action of the first driving wheel 15 and the first belt 16, the second driven wheel 17 rotates, which in turn causes the worm 18 to rotate, and the rotation of the worm 18 drives the worm wheel 35 to rotate, which in turn causes the fourth rotating shaft 37 to rotate, thereby driving the fan blades 36 to rotate, and then cooling the calendered plastic floor.

[0059] Then, the first motor 8 is started, and the first motor 8 drives the winding roller 6 to rotate, so as to collect the processed plastic floor.

[0060] Embodiment 2

[0061] The present embodiment is different from the first embodiment in that the second connecting shaft 38 and the third connecting shaft 42 are fixedly arranged on the top of the two fourth rotating shafts 37. The circumferential surface of the second connecting shaft 38 is fixedly sleeved with the fourth driven wheel 41, and the circumferential surface of the third connecting shaft 42 is fixedly sleeved with the fourth driving wheel 43 and the fifth driven wheel 44. The fourth belt 39 is sleeved between the first driving wheel 15 and the fifth driven wheel 44, and the fifth belt 40 is sleeved between the fourth driving wheel 43 and the fourth driven wheel 41.

[0062] The rotation of the first driving wheel 15 drives the fifth driven wheel 44 to rotate through the fourth belt 39 , thereby causing the third connecting shaft 42 to rotate.

[0063] The rotation of the third connecting shaft 42 will drive the fourth driving wheel 43 to rotate, and the fourth driven wheel 41 will rotate under the action of the fourth driving wheel 43 and the fifth belt 40, thereby driving the second connecting shaft 38 to rotate. Finally, the two fourth rotating shafts 37 rotate under the action of the second connecting shaft 38 and the third connecting shaft 42, and finally the fan blades 36 rotate, so as to cool the calendered plastic floor.

[0064] How it works

[0065] The difference between this embodiment and the second embodiment is that the rotation of the first driving wheel 15 drives the fifth driven wheel 44 to rotate through the fourth belt 39, thereby causing the third connecting shaft 42 to rotate. The rotation of the third connecting shaft 42 drives the fourth driving wheel 43 to rotate, and the fourth driven wheel 41 rotates under the action of the fourth driving wheel 43 and the fifth belt 40, thereby driving the second connecting shaft 38 to rotate. Finally, the two fourth rotating shafts 37 rotate under the action of the second connecting shaft 38 and the third connecting shaft 42, and finally the fan blades 36 rotate, so as to cool the calendered plastic floor.
