[0025] As shown in the accompanying drawings, the utility model includes a cooling device 120 and a cooling flattening device 130 which are sequentially installed on one side of the discharge end of the calender 110. The rubber after being pressed by the calender 110 sequentially enters the cooling device 120 for primary cooling, and then enters the cooling flattening device 130 for secondary cooling and shaping.
[0026] The structure and working principle of the cooling device 120:
[0027] The cooling device 120 includes a cooling water pool 30, which is an inverted trapezoidal structure with a wide top and a narrow bottom. A feed roller 31 is provided at the front end position of the top of the cooling water pool 30, a traction assembly 32 is provided at the rear end position of the top of the cooling water pool 30, and an air drying assembly 34 is provided on the cooling water pool 30 located in front of the traction assembly 32. A first blowing pipe 35 is provided on the inner side of the inclined surface at the front end of the cooling water pool 30.
[0028] The rubber flattened by the calender 110 is pulled into the cooling water pool 30, and the first blowing pipe 35 blows a high-speed airflow toward the rear end of the cooling water pool 30, so that the water in the cooling water pool 30 flows back and forth, and the flowing water transports the rubber to the rear end of the cooling water pool 30. The staff takes out the rubber and passes it through the air-drying component 3 and the traction component 32 in turn. After the traction component 32 is started, the rubber is transported backward in turn. The rubber is cooled when passing through the cooling water pool 30, and the water stains attached to the rubber are blown off when the rubber passes through the air-drying component 3.
[0029] A rubber pressing roller 37 is provided in the middle of the cooling water pool 30, and the rubber pressing roller 37 and the first blowing pipe 35 are both located below the water level. The rubber pressing roller 37 is located above the rubber, so that the rubber is always immersed below the water level in the cooling water pool 30. The opening direction of the first blowing pipe 35 is inclined upward toward the rear end of the cooling water pool 30.
[0030] The traction assembly 32 includes a lower clamping roller 38, an upper clamping roller 39 and a pair of upper clamping roller lifting cylinders 40. The lower clamping roller 38 is rotatably installed at the rear end of the cooling water pool 30. A lower clamping roller driving motor 401 for driving the lower clamping roller 38 to rotate is provided on one side of the cooling water pool 30. The upper clamping roller 39 is movably installed on the cooling water pool 30 through a pair of upper clamping roller lifting cylinders 40 and is located above the lower clamping roller 38.
[0031] The roller surface of the lower clamping roller 38 is provided with anti-skid patterns.
[0032] Under default conditions, the upper clamping roller 39 is lifted upward by a pair of upper clamping roller lifting cylinders 40. When the rubber passes through, the upper clamping roller 39 moves downward to cooperate with the lower clamping roller 38 to clamp the rubber, and then the lower clamping roller drive motor 401 is started to drive the rubber to move forward slowly.
[0033] The air-drying component 34 includes an upper air knife 41 and a lower air knife 42. A group of water filter holes 43 are provided on the inner side of the inclined surface at the rear end of the cooling water pool 30. The lower air knife 42 is installed on the water filter holes 43. The upper air knife 41 is installed on the cooling water pool 30 through a bracket and is located above the lower air knife 42, and the upper air knife 41 and the lower air knife 42 are staggered front and back.
[0034] The width of the upper air knife 41 and the lower air knife 42 is the same as the width of the cooling water pool 30, and the water stains on the upper surface and the lower surface of the rubber are cleaned from the upper and lower directions respectively.
[0035] The air outlet directions of the upper air knife 41 and the lower air knife 42 are both inclined toward the front end of the cooling water pool 30. The air outlet direction of the upper air knife 41 is inclined downward, and the air outlet direction of the lower air knife 42 is inclined upward. The upper air knife 41 is located in front of the lower air knife 42.
[0036] A drain pipe 45 is provided on the cooling water pool 30 located on one side of the water filter hole 43, and a water supply pipe 46 is provided above the front end of the cooling water pool 30. The water supply pipe 46 supplies water to the cooling water pool 30, and the water stains brought out by the rubber belt and the water flowing in the upper layer of the cooling water pool 30 are discharged through the drain pipe 45 after passing through the water filter hole 43. The discharged water enters the water storage tank for cooling and then enters through the water supply pipe 46 for recycling, so that the water level and water temperature in the cooling water pool 30 remain stable.
[0037] An arc-shaped support portion 47 protruding upward is provided on the cooling water pool 30 located at the rear side of the air outlet of the lower air knife 42. The arc-shaped support portion 47 allows the rubber to have a certain gap with the lower air knife 42 when the rubber passes through the lower air knife 42, so that the lower air knife 42 can blow off the water stains on the bottom of the rubber.
[0038] The structure and working principle of the cooling and flattening device 130:
[0039] The cooling and flattening device 130 includes a closed water tank 50 , a top of which is provided with a flattening roller 51 that can move forward and backward, a front end of the closed water tank 50 is provided with a first glue pressing component 52 , and a rear end of the closed water tank 50 is provided with a second glue pressing component 53 .
[0040] The rubber sheet that has been preliminarily cooled by the cooling device 120 is laid flat on the top of the closed water tank 50. The laying roller 51 is located below the rubber sheet and partially props up the rubber sheet. A gap is provided between the laying roller 51 and the closed water tank 50, so that the laying roller 51 can rotate under the friction of the rubber sheet when moving back and forth, thereby flattening the rubber sheet. At the same time, the laying roller 51 sequentially props up the bottom of the rubber sheet and separates it from the closed water tank 50, so that the heat is quickly dissipated. The two ends of the rubber sheet are clamped by the first glue pressing component 52 and the second glue pressing component 53 respectively. The closed water tank 50 is filled with water, and a water inlet is provided at the rear end and a drain outlet is provided at the front end, so that water flows in the closed water tank 50, thereby taking away the heat of the laid rubber sheet.
[0041] Synchronous belt electric slides 54 are respectively provided on both sides of the closed water tank 50, and the flattening roller 51 moves forward and backward on the closed water tank 50 through the synchronous belt electric slides 54. The two ends of the flattening roller 51 are respectively installed on the sliders of the synchronous belt electric slides 54 through the connecting seats, and the two synchronous belt electric slides 54 act synchronously, so that the flattening roller 51 can keep moving horizontally.
[0042] The sliders of the two synchronous belt electric slides 54 are both provided with a pair of second blowing pipes 55 with openings facing the horizontal center line of the closed water tank 50. The pair of second blowing pipes 55 are symmetrically located at the front and rear sides of the slider. The second blowing pipes 55 are connected to an external high-pressure air source. When the flattening rollers 51 move forward and backward, they partially prop up the rubber sheet so that it is separated from the closed water tank 50. At this time, the second blowing pipes 55 blow cold air into the propped-up gap to dissipate the heat in the gap between the rubber sheet and the closed water tank 50.
[0043] The second glue pressing assembly 53 includes a support frame 58 and a pressure plate lifting cylinder 59 installed on the support frame 58. Slide rails 57 are respectively provided on both sides of the closed water tank 50. The two ends of the support frame 58 are respectively adjustably installed on the closed water tank 50 through the slide rails 57. A first clamping plate 60 is provided on the piston rod of the pressure plate lifting cylinder 59.
[0044] According to the flattened length of the rubber sheet, the support frame 58 can adjust the position on the closed water tank 50 through the slide rail 57. The length of the first pressing plate 60 is not greater than the width of the closed water tank 50. The two ends of the first pressing plate 60 are respectively provided with guide rods, and the support frame 58 is provided with guide holes that match the guide rods, so that the first pressing plate 60 can remain stable and evenly stressed. In order to prevent the first pressing plate 60 from sticking to the rubber sheet, a release agent can be sprayed on the bottom of the first pressing plate 60.
[0045] The first glue pressing assembly 52 includes a second pressing plate 62 and a pressing cylinder 63. The second pressing plate 62 is movably installed at the front end of the closed water tank 50 through a lever 64. The pressing cylinder 63 is installed at the bottom of the closed water tank 50 and drives the second pressing plate 62 to swing up and down through the lever 64.
[0046] The front top of the closed water tank 50 is an inclined surface. The inclined surface cooperates with the second pressing plate 62 to shorten the stroke of the second pressing plate 62. Before use, a release agent is sprayed on the bottom of the second pressing plate 62 to prevent it from sticking to the rubber sheet, so that the rubber sheet can be smoothly separated from the second pressing plate 62 when loosened.
[0047] The closed water tank 50 is divided into a plurality of cooling water channels that pass through the front and rear through a group of partitions 66. The rear end of the closed water tank 50 is provided with a plurality of water inlets corresponding to the cooling water channels, and the front end of the closed water tank 50 is provided with a plurality of drainage outlets corresponding to the cooling water channels.
[0048] Each cooling water channel is an independent entity, so that the entire closed water tank 50 dissipates heat evenly. At the same time, each partition 66 also acts as a reinforcing rib to prevent the top of the closed water tank 50 from being deformed by heat, so that the top remains flat.
