Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a rubber mixing cooling system. Background Art

[0002] Rubber refining is a process in which a rubber refining machine shears and mixes the raw rubber through the rotation of two differential pressing rollers, and then flattens it through a calender and naturally cools it down to set it. On the existing rubber refining production line, after the raw rubber of the rubber refining machine comes out of the gap between the two differential pressing rollers, it is necessary to manually cut and roll up the rubber sheet attached to the pressing, and then change the direction and continue to put it into the two differential pressing rollers, and repeat in sequence. When the raw rubber is put into the two differential pressing rollers, it is difficult to eat the rubber due to the smooth roller surface, and it is necessary to manually apply pressure to the gap between the two differential pressing rollers. The labor intensity is high, time-consuming and labor-intensive, and it is also dangerous.

[0024] As shown in the accompanying drawings, the utility model comprises an open mill 100, a calender 110 and a cooling device 120 which are arranged in sequence from front to back.

[0025] After the rubber is mixed by the open mixing mill 100, it is put into the calender 110 for extrusion and flattening to a set thickness. The calender 110 in this case is a four-roll rubber calender. Then the flattened rubber is introduced into the cooling device 120 for cooling and shaping.

[0026] The structure and working principle of the mixing mill 100:

[0027] A pressing device is provided above the rubber feeding part of the open mixing mill 100, and the pressing device includes a pair of feeding pressing rollers 6 and a pressing cylinder 7 that drives the pair of feeding pressing rollers 6 to press alternately up and down. The open mixing mill 100 includes a machine base 1, a front pressing roller 2, a rear pressing roller 3 and a pressing device, the front pressing roller 2 is installed on the machine base 1 in a fixed position, the rear pressing roller 3 is installed on the machine base 1 in a forward and backward adjustable manner, and the machine base 1 is respectively provided with a first driving motor 4 that drives the front pressing roller 2 to rotate and a second driving motor 5 that drives the rear pressing roller 3 to rotate; the pressing device includes a pair of feeding pressing rollers 6 and a pressing cylinder 7 that drives the pair of feeding pressing rollers 6 to press alternately up and down, and the pair of feeding pressing rollers 6 are located above the gap between the front pressing roller 2 and the rear pressing roller 3.

[0028] The rotation speeds of the first drive motor 4 and the second drive motor 5 are different, resulting in different rotation speeds of the front pressing roller 2 and the rear pressing roller 3. The raw rubber is put into the gap between the front pressing roller 2 and the rear pressing roller 3 and is squeezed by the front pressing roller 2 and the rear pressing roller 3. At the same time, the raw rubber is torn and refined due to the different rotation speeds.

[0029] After being squeezed, the raw rubber adheres to the front pressing roller 2. The staff needs to cut the film and then roll up the pressed film, and then change the direction and put it into the gap between the front pressing roller 2 and the rear pressing roller 3 for secondary rubber refining. When the film is rolled up and put in, due to the smooth roller surface, it is difficult for the front pressing roller 2 and the rear pressing roller 3 to eat the rubber, and the raw rubber cannot quickly enter the gap. At this time, the pressing cylinder 7 starts and drives a pair of feeding pressing rollers 6 to alternately press the raw rubber downward, applying a downward pressing force to it, so that the raw rubber can quickly enter the gap, thereby improving the rubber refining efficiency.

[0030] Guide grooves are provided on the inner sides of the two vertical plates of the machine base 1, and an adjusting slider 10 is provided in the guide groove. The two ends of the rear pressing roller 3 are respectively installed on the two adjusting sliders 10 through bearings. The second driving motor 5 is installed on one of the adjusting sliders 10 through a supporting plate. The two adjusting sliders 10 are connected by a connecting plate 12. An adjusting screw 13 for controlling the forward and backward movement of a pair of adjusting sliders 10 is provided at the end of the machine base 1.

[0031] The adjusting screw rod 13 and a pair of adjusting sliders 10 form a screw rod slide, which is used to quickly adjust the gap between the rear pressing roller 3 and the front pressing roller 2. That is, the positions of the two ends of the rear pressing roller 3 can be synchronously adjusted by an adjusting screw rod 13.

[0032] A mounting frame 15 is provided on the top of the machine base 1, and a lever 16 is provided on the mounting frame 15. Fork frames 17 for mounting a feeding pressure roller 6 are provided at both ends of the lever 16. The pressing cylinder 7 is installed on the mounting frame 15 and drives one of the fork frames 17 to move up and down. The two fork frames 17 move up and down alternately through the lever 16.

[0033] The middle part of the lever 16 is hinged on the mounting frame 15. After the pressing cylinder 7 is started, it drives one of the fork frames 17 to move, and the lever 16 moves the other fork frame 17 to the opposite direction, that is, it controls the action of a pair of feeding rollers 6 to press down alternately up and down.

[0034] The fork frame 17 is a Y-shaped fork frame, a vertical limiting hole is provided on the fork handle in the middle of the Y-shaped fork frame, and a limiting rod matched with the vertical limiting hole is provided on the mounting frame 15.

[0035] During specific installation, both ends of the lever 16 are hinged to the fork handle of the Y-shaped fork frame, and the hinge holes at both ends of the lever 16 are long holes to avoid interference and jamming when the fork handle moves up and down.

[0036] The fork handle and fork body of the Y-shaped fork frame are hinged by a pin shaft. That is, the fork body can swing around the fork handle. The raw film roll has an irregular structure. When the feeding roller 6 is pressed down and subjected to the reaction force of the raw film roll, the feeding roller 6 changes its horizontal state and one end is tilted to play a buffering role. Under the weight of the feeding roller 6 and the thrust of the pressing cylinder 7, the raw film roll can be pressed downward more evenly. Springs 18 connected to the mounting frame 15 are respectively provided at both ends of the fork body.

[0037] Spring 18 is a tensioning spring, which is used to apply a supporting force to the two ends of the fork body so that the two ends of the fork body remain parallel. When squeezing the raw film roll, the two ends of the feeding roller 6 are subjected to uneven force, and one end is tilted. Under the action of spring 18, the tilting amplitude of the feeding roller 6 can be effectively controlled. At the same time, when the fork body is lifted upward, the shaking of the fork body is also effectively prevented.

[0038] A film cutting assembly is provided on the machine base 1 located at one side of the front pressing roller 2 . The film cutting assembly includes a cutting electric slide 19 and a cutter 20 installed on a slider of the cutting electric slide 19 .

[0039] The cutting electric slide 19 is an electric screw slide, which can be controlled by a pedal switch. After the cutting electric slide 19 is started, the cutter 20 can quickly cut the film attached to the front pressing roller 2, so that the staff can quickly roll up the film.

[0042] The rubber flattened by the calender 110 is pulled into the cooling water pool 30, and the 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.

[0043] A rubber pressing roller 37 is provided in the middle of the cooling water pool 30, and the rubber pressing roller 37 and the 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 blowing pipe 35 is inclined upward toward the rear end of the cooling water pool 30.

[0044] 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.

[0045] The roller surface of the lower clamping roller 38 is provided with anti-skid patterns.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.
