Description

Technical Field

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

[0002] Rubber mixing is a process in which the rubber mixer 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. In the existing rubber mixing production line, after the raw rubber of the rubber mixer 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. It is necessary to manually apply pressure to the gap between the two differential pressing rollers, which is labor-intensive, time-consuming and labor-intensive, and also has certain risks.

[0003] Secondly, the temperature of the rubber after being rolled and flattened is high, making it easy to stick to the rubber. Therefore, it needs to be cooled before it can be cut. The existing cooling method is mostly to lay it flat on the ground for natural cooling, which takes a long time and occupies a large area.

[0004] In addition, during the cooling process, the film is prone to local warping and wrinkling, which affects the quality of the film after cutting. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] As shown in the accompanying drawings, the utility model comprises an open mill 100, a calender 110, a cooling device 120 and a cooling and flattening device 130 which are arranged in sequence from front to back.

[0033] 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 primary cooling, and then moved to the cooling and flattening device 130 for secondary cooling and flattening, so that the rubber is more flat.

[0034] The structure and working principle of the mixing mill 100:

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] A mounting frame 15 is provided on the top of the machine base 1, and a first lever 16 is provided on the mounting frame 15. Fork frames 17 for mounting a feeding roller 6 are provided at both ends of the first 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 first lever 16.

[0041] The middle part of the first 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 first 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.

[0042] 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.

[0043] During specific installation, both ends of the first lever 16 are hinged to the fork handle of the Y-shaped fork frame, and the hinge holes at both ends of the first lever 16 are long holes to avoid interference and jamming when the fork handle moves up and down.

[0044] 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.

[0045] 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 pressure roller 6 are subjected to uneven force, and one end is tilted. Under the action of spring 18, the tilting amplitude of the feeding pressure 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.

[0046] 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 .

[0047] 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.

[0048] The structure and working principle of the cooling device 120:

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] The roller surface of the lower clamping roller 38 is provided with anti-skid patterns.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] The structure and working principle of the cooling and flattening device 130:

[0061] 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 .

[0062] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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 second 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 second lever 64.

[0068] 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.

[0069] 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.

[0070] Each cooling water channel is an independent entity, so that the heat dissipation of the entire closed water tank 50 is uniform. 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 of the closed water tank 50 remains flat.
