[0031] like Figure 1 , Figure 3 and Figure 4 As shown, a cold return structure is provided on the top of the operating table 20, and the cold return structure includes a cooling table 31 and a water leakage trough 34. The cooling table 31 is fixedly connected to the top of the operating table 20, and the water leakage trough 34 is opened through the top of the cooling table 31. The cold return structure can cool the rubber.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, a rectangular groove adapted to the size of the water pool 26 is provided on the top of the operating table 20, and the water pool 26 is fixedly connected in the rectangular groove on the top of the operating table 20. The top of the cooling table 31 is an inclined surface with an inclined angle, and the lowest part of the top inclined surface of the cooling table 31 also has a flat wall surface at one end. The leakage groove 34 is provided at the flat part of the top of the cooling table 31, and the position of the leakage groove 34 is vertically above the top opening of the water pool 26. The highest part of the inclined surface of the cooling table 31 is lower than the discharge port 22. The bottom of the pumping structure 24 is aligned with the highest part of the inclined surface of the cooling table 31, and the leakage groove 34 is a circular groove. A plurality of leakage grooves 34 are evenly provided on the wall surface of the cooling table 31. The cold return structure also includes a top frame 30, a dividing edge 32, a protective edge 33 and a stop slope 35. The top frame 30 is symmetrically fixedly connected to the top of the operating table 20, and the cooling table 31 is fixedly connected between the symmetrical top frames 30. The dividing edge 32 is fixedly connected to the top of the cooling table 31, the edge guard 33 is symmetrically fixedly connected on both sides of the top of the cooling table 31, the stop slope 35 is fixedly connected to the flat wall surface of the top of the cooling table 31, the section of the dividing edge 32 is an isosceles triangle, the length of the dividing edge 32 is consistent with the top of the cooling table 31, the dividing edge 32 is fixedly connected to the center of the top of the cooling table 31, the edge guard 33 is a right triangle, the flat surface of the edge guard 33 is flush with the side wall surface of the cooling table 31, the inclined surfaces on both sides of the dividing edge 32 correspond to the inclined surfaces of the edge guards 33 on both sides respectively, the size of the edge guard 33 is consistent with the dividing edge 32, the section of the stop slope 35 is a right triangle, the inclined surface of the stop slope 35 faces the inclined surface of the top of the cooling table 31, the front wall surface of the stop slope 35 is flush with the front wall surface of the cooling table 31, and the leakage groove 34 is arranged on the flat wall surface of the top of the cooling table 31 between the inclined surface of the stop slope 35 and the inclined surface of the cooling table 31;

[0033] During specific use, the cavity of the water tank 26 is filled with water for cooling. The rubber to be extrusion-molded is added into the cavity of the extruder 21 for extrusion, and the power supply is turned on. At this time, the water pumping structure 24 can pump up the water in the cavity of the water tank 26 through the water pipe 25. The water pumping structure 24 can pump up the water in the cavity of the water tank 26 and discharge it from the bottom of the water pumping structure 24, so that the water flows on the top of the cooling table 31. At this time, the extruder 21 will extrude the rubber into a mold and discharge it from the discharge port 22. When the rubber is discharged from the discharge port 22, it will directly fall on the top of the cooling table 31 between the partition edge 32 and the protective edge 33. At this time, there is already water flowing from the inclined top of the cooling table 31 towards the inclined bottom of the cooling table 31. The rubber will move on the top of the cooling table 31 in the water and move towards the flat wall surface at the top of the cooling table 31. When the water flow flows from the inclined surface of the cooling table 31 to the flat surface of the cooling table 31, it will be blocked by the inclined surface of the flow-stopping slope 35 and then directly leak down from the water leakage groove 34 and drip into the cavity of the water tank 26. Thus, the water circulation is completed. When the rubber moves to the flat surface of the cooling table 31, it will continue to move from the inclined surface of the flow-stopping slope 35 and then pass through between the bottom of the cleaning rod 36 and the top of the flow-stopping slope 35. A brush is installed at the bottom of the cleaning rod 36, and the brush can wipe the water remaining on the wall surface of the rubber. The wiped water will enter from the top of the water passing plate 38 or move towards the water leakage groove 34 from the inclined surface of the flow-stopping slope 35, and finally will still enter the cavity of the water tank 26. Thus, the cooling of the rubber after extrusion is completed;

[0034] In summary, by setting up the cooling and recycling structure, the rubber can be cooled at low cost. Because the cooling and recycling structure recycles and reuses the water for cooling the rubber after use, and this cooling and recycling process does not cause a large amount of water consumption. And when the water flow is recycled, it will not cause heat accumulation due to contact with the air. Thus, the rubber can be cooled at low cost. Therefore, compared with the prior art, this solution uses less water and has lower cost when cooling the rubber.

[0035] As Figure 1 and Figure 3 shown, the cooling and recycling structure further includes a cleaning rod 36, a baffle 37 and a water passing plate 38. The cleaning rod 36 is fixedly connected to the tops of the protective edge 33 and the partition edge 32. The cleaning rod 36 is symmetrically arranged on both sides of the inclined surface of the partition edge 32. The bottom size of the cleaning rod 36 is the same as the inclined surfaces of one side of the partition edge 32 and the protective edge 33. The baffle 37 is fixedly connected to the bottom of the flat wall surface of the cooling table 31. The water passing plate 38 is fixedly connected to the front wall surface of the flat wall surface of the cooling table 31. The cross-section of the baffle 37 is in a C shape. The three outer wall surfaces of the baffle 37 are flush with the front wall surface and both sides at the bottom of the flat surface of the cooling table 31. The bottom of the baffle 37 can enter the cavity of the water tank 26. The top and the cavity of the water passing plate 38 are hollow. The baffle 37 is communicated with the cavity of the water passing plate 38 at the position where it is connected to the rear wall surface of the water passing plate 38;

[0036] When in use, when the rubber moves to the flat surface of the cooling table 31, it will continue to move from the inclined surface of the stop flow slope 35 and then pass between the bottom of the cleaning rod 36 and the top of the stop flow slope 35. A brush is installed at the bottom of the cleaning rod 36, and the brush can wipe the water remaining on the rubber wall. The wiped water will enter from the top of the water passing plate 38 or move from the inclined surface of the stop flow slope 35 toward the leakage groove 34, and finally flow back into the water pool 26 cavity;

[0037] In summary, by providing a brush capable of wiping the rubber, the water stains remaining on the rubber wall can be scraped off, and the scraped water can flow back to the water pool 26, thereby improving the water recovery efficiency of the device and also simply cleaning the rubber wall.

[0038] like Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, a winding structure is also provided on the top of the operating table 20, and the winding structure includes a frame 40, a first rotating motor 41, a rotating shaft 42, a rotating disk 43, a connecting rod 44, a second rotating motor 45 and a receiving roller 46. The frame 40 is symmetrically arranged on the top of the operating table 20, the first rotating motor 41 is fixedly connected to the side wall of the frame 40, the number of the first rotating motors 41 is the same as that of the frame 40, the rotating shaft 42 is rotatably connected to the other side wall of the frame 40 opposite to the first rotating motor 41, the rotating shaft 42 can pass through the frame 40 and be connected to the output end of the first rotating motor 41, the rotating disk 43 is fixedly connected to the wall of the rotating shaft 42, the connecting rod 44 is fixedly connected to the wall of the rotating disk 43, and the second rotating motor 45 is connected to the receiving roller 46. 5 and the receiving roller 46 are arranged opposite to each other on the wall surfaces of both sides of the connecting rod 44, the second rotating motor 45 is fixedly connected to the wall surface of the connecting rod 44, the receiving roller 46 is rotatably connected to the wall surface of the connecting rod 44, the end of the receiving roller 46 can pass through the connecting rod 44 and be connected to the output end of the second rotating motor 45, the first rotating motor 41, the rotating shaft 42, the rotating disk 43, the connecting rod 44, the second rotating motor 45 and the receiving roller 46 are all symmetrically arranged on the top of the operating table 20, the rotating shaft 42 is cylindrical, the rotating disk 43 is disc-shaped, the connecting rod 44, the second rotating motor 45 and the receiving roller 46 are arranged in a circular array on the arc surface of the rotating disk 43, the receiving roller 46 is also cylindrical, and the symmetrical receiving rollers 46 face each other;

[0039] During specific use, the first rotating motor 41 and the second rotating motor 45 are electrically connected to the corresponding power supply. When the rubber passes between the stop slope 35 and the cleaning rod 36, the staff manually wraps the rubber around the wall surface of the receiving roller 46, and then the second rotating motor 45 drives the receiving roller 46 to rotate to reel up the rubber. After a single receiving roller 46 has finished reeling up the rubber, the first rotating motor 41 will drive the rotating shaft 42 to rotate, thereby driving another receiving roller 46 to reel up the cleaning rod 36 that has been reeled up. When the second cleaning rod 36 is reeled up, the rubber that has been reeled up on the wall surface of the cleaning rod 36 that has been reeled up in advance can be removed, thereby completing the entire rubber extrusion and cooling process.

[0040] In summary, by providing the cleaning rod 36 , the rubber can be continuously rolled up, because the rubber is continuously rolled up by rotating a plurality of cleaning rods 36 , thereby improving the efficiency of the device when rolling up the rubber.

[0041] like Figure 5 and Figure 7 As shown, the winding structure further includes a connecting block 47 and an anti-slip plate 48. The connecting block 47 is fixedly connected to the top of the operating table 20 between the symmetrical storage rollers 46. The anti-slip plate 48 is fixedly connected to the top of the connecting block 47. The end of the storage roller 46 can contact the side wall of the anti-slip plate 48. The anti-slip plate 48 is semi-annular, and the side wall of the storage roller 46 can contact along the wall of the anti-slip plate 48.

[0042] In specific use, when the cleaning rod 36 is rolling up the rubber, the end of the cleaning rod 36 will contact the anti-slip plate 48. After the cleaning rod 36 is rolled up and driven by the turntable 43 to rotate, the wall surface of the cleaning rod 36 that has been rolled up will not contact the wall surface of the anti-slip plate 48 after rotation.

[0043] In summary, by providing the anti-slip plate 48, the rubber can be prevented from falling off the wall of the cleaning rod 36 when the storage roller 46 reels the rubber, because the anti-slip plate 48 will block the originally open side wall of the cleaning rod 36 when the cleaning rod 36 is reeled in, thereby preventing the rubber from falling off, thereby increasing the stability of the device operation.

[0044] Working principle: Fill the water tank 26 cavity with cooling water, add the rubber to be extruded into the cavity of the extruder 21 for extrusion, and turn on the power. At this time, the pumping structure 24 can pump up the water in the water tank 26 cavity through the water pipe 25. The pumping structure 24 can pump up the water in the water tank 26 cavity and discharge it from the bottom of the pumping structure 24 so that the water flows on the top of the cooling table 31. At this time, the extruder 21 will extrude the rubber and discharge it from the discharge port 22. When the rubber is discharged from the discharge port 22, it will directly fall on the top of the cooling table 31 between the dividing edge 32 and the edge guard 33. At this time, there is water on the top of the slope of the cooling table 31 flowing toward the bottom of the slope of the cooling table 31, and the rubber will move on the top of the cooling table 31. When the water flows from the inclined surface of the cooling platform 31 to the flat surface of the cooling platform 31, it will be blocked by the inclined surface of the stop slope 35 and then directly leak from the leakage groove 34 and then drip into the water pool 26 cavity to complete the water circulation. When the rubber moves to the flat surface of the cooling platform 31, it will continue to move from the inclined surface of the stop slope 35 and then pass between the bottom of the cleaning rod 36 and the top of the stop slope 35. A brush is installed at the bottom of the cleaning rod 36. The brush can wipe the water remaining on the rubber wall. The wiped water will enter from the top of the water-passing plate 38 or move from the inclined surface of the stop slope 35 toward the leakage groove 34, and finally enter the water pool 26 cavity to complete the cooling of the rubber after extrusion.
