Description

Technical Field

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

[0002] Rubber mixing involves shearing and mixing the raw rubber through the rotation of two differential-speed rollers in a rubber mixing mill. The raw rubber is then flattened by a calender, naturally cooled and shaped, and finally cut as needed. On existing rubber mixing lines, after the raw rubber emerges from the gap between the two differential-speed rollers, it must be manually cut and rolled up. The rubber then reverses direction and continues feeding it into the two differential-speed rollers, repeating this process. Due to the smooth roller surfaces, the raw rubber has difficulty feeding into the gap between the two differential-speed rollers, requiring manual pressure to be applied to the gap between the two rollers. This process is labor-intensive, time-consuming, and labor-intensive, as well as potentially dangerous.

[0003] Secondly, the temperature of the rubber after being rolled and flattened is high, making it sticky. Therefore, it needs to wait until it cools down before it can be cut. The existing cooling method is mostly to lay the rubber flat on the ground for natural cooling. This method takes a long time and occupies a large area. In addition, during the cooling process, the film is prone to warping and wrinkling in some parts, affecting the quality of the film after cutting.

[0004] When cutting rubber, existing cutting methods often rely on manual alignment and control of the cutting machine, resulting in low cutting efficiency. Furthermore, when feeding the rubber sheet flat, it tends to stick to the cutting table, creating friction and making feeding difficult. This can also cause deformation during the cutting process, impacting cutting accuracy. Utility Model Content

[0040] As shown in the accompanying drawings, the present invention comprises an open mill 100, a calender 110, a cooling device 120, a cooling and flattening device 130 and a slicer 140 which are arranged in sequence from front to back.

[0041] After being mixed in an open mixing mill 100, the rubber is then extruded and flattened to a desired thickness in a calender 110, a four-roller rubber calender in this case. The flattened rubber is then passed into a cooling unit 120 for primary cooling, and then into a cooling and flattening unit 130 for secondary cooling and flattening, further flattening the rubber. Finally, the cooled rubber is passed to a slicer 140 for primary slicing.

[0042] Structure and working principle of mixing mill 100:

[0043] 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 rollers 6 and a pressing cylinder 7 that drives the pair of feeding 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 mounted on the machine base 1 in a fixed position, and the rear pressing roller 3 is mounted on the machine base 1 in a forward and backward adjustable manner. The machine base 1 is respectively provided with a first drive motor 4 that drives the front pressing roller 2 to rotate and a second drive motor 5 that drives the rear pressing roller 3 to rotate; the pressing device includes a pair of feeding rollers 6 and a pressing cylinder 7 that drives the pair of feeding rollers 6 to press alternately up and down. The pair of feeding rollers 6 are located above the gap between the front pressing roller 2 and the rear pressing roller 3.

[0044] The first drive motor 4 and the second drive motor 5 have different rotational speeds, resulting in different rotational 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 rotational speeds.

[0045] 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 mixing. 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 mixing efficiency.

[0046] 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 drive motor 5 is installed on one of the adjusting sliders 10 through a support plate. The two adjusting sliders 10 are connected by a connecting plate 12. The end of the machine base 1 is provided with an adjusting screw 13 for controlling the forward and backward movement of a pair of adjusting sliders 10.

[0047] The adjusting screw rod 13 and a pair of adjusting sliders 10 form a screw rod slide for quickly adjusting 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.

[0048] 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. Both ends of the first lever 16 are respectively provided with fork frames 17 for mounting the feeding roller 6. 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.

[0049] 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 in the opposite direction, that is, it controls the action of a pair of feeding rollers 6 to press down alternately up and down.

[0050] 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 that matches the vertical limiting hole is provided on the mounting frame 15.

[0051] 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.

[0052] The Y-shaped fork's handle and body are hingedly connected by a pin. This allows the fork to swing around the handle. The raw film roll has an irregular structure. When the loading roller 6 presses downward and is subjected to the reaction force of the raw film roll, the loading roller 6 changes its horizontal position, tilting one end to act as a buffer. Under the weight of the loading roller 6 and the thrust of the pressing cylinder 7, a relatively uniform downward pressure is applied to the raw film roll. Springs 18 connected to the mounting bracket 15 are provided at each end of the fork.

[0053] The 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, the two ends of the feeding pressure roller 6 are unevenly stressed, and one end is tilted. Under the action of the 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, it can also effectively prevent the fork body from shaking.

[0054] A film cutting assembly is provided on the machine base 1 located on one side of the front pressing roller 2 . The film cutting assembly includes a cutting electric slide 19 and a cutter 20 mounted on a slider of the cutting electric slide 19 .

[0055] 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, making it convenient for the staff to quickly roll up the film.

[0056] The structure and working principle of the cooling device 120:

[0057] 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 first feed roller 31 is provided at the front end of the top of the cooling water pool 30, a traction assembly 32 is provided at the rear end 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.

[0058] 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. 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.

[0059] A rubber pressing roller 37 is located in the middle of the cooling water pool 30. Both the rubber pressing roller 37 and the first blowing pipe 35 are located below the water level. The rubber pressing roller 37 is positioned above the rubber, ensuring that the rubber remains submerged below the water level in the cooling water pool 30. The opening of the first blowing pipe 35 is angled upward, toward the rear end of the cooling water pool 30.

[0060] 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 mounted at the rear end of the cooling water pool 30. A lower clamping roller driving motor 401 is provided on one side of the cooling water pool 30 to drive the lower clamping roller 38 to rotate. The upper clamping roller 39 is movably mounted 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.

[0061] The roller surface of the lower clamping roller 38 is provided with anti-slip grooves.

[0062] Under the default condition, the upper pinch roller 39 is pushed upward by a pair of upper pinch roller lifting cylinders 40. When the rubber passes through, the upper pinch roller 39 moves downward to cooperate with the lower pinch roller 38 to clamp the rubber, and then the lower pinch roller drive motor 401 is started to drive the rubber to move forward slowly.

[0063] 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 hole 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. The upper air knife 41 and the lower air knife 42 are staggered front and back.

[0064] 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.

[0065] 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.

[0066] A drain pipe 45 is provided on the cooling water pool 30, located on one side of the water filter hole 43. A water supply pipe 46 is provided above the front end of the cooling water pool 30. The water supply pipe 46 replenishes the cooling water pool 30. Water stains from the rubber belt and water flowing through 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, cools, and then enters the water pool 30 through the water supply pipe 46 for recycling, thereby maintaining a stable water level and temperature in the cooling water pool 30.

[0067] An upwardly protruding arc-shaped support portion 47 is provided on the cooling water pool 30 behind the air outlet of the lower air blade 42. The arc-shaped support portion 47 allows the rubber to have a certain gap between the bottom of the rubber and the lower air blade 42 when passing through the position of the lower air blade 42, making it easier for the lower air blade 42 to blow away water stains on the bottom of the rubber.

[0068] The structure and working principle of the cooling and flattening device 130:

[0069] The cooling and flattening device 130 includes a closed water tank 50, the top of which is provided with a flattening roller 51 that can move forward and backward, the front end of the closed water tank 50 is provided with a first glue pressing component 52, and the rear end of the closed water tank 50 is provided with a second glue pressing component 53.

[0070] After preliminary cooling by the cooling device 120, the rubber sheet is laid flat on top of the closed water tank 50. The laying rollers 51 are located below the rubber sheet, partially supporting the rubber sheet. A gap is provided between the laying rollers 51 and the closed water tank 50, allowing the laying rollers 51 to rotate under the friction of the rubber sheet as they move back and forth, thereby flattening the rubber sheet. Simultaneously, the laying rollers 51 sequentially support the bottom of the rubber sheet and separate it from the closed water tank 50, allowing heat to dissipate quickly. The two ends of the rubber sheet are clamped by the first and second glue pressing assemblies 52, 53, respectively. The closed water tank 50 is filled with water, with a water inlet at the rear end and a drain at the front end, allowing water to flow within the closed water tank 50, thereby removing heat from the laid rubber sheet.

[0071] A synchronous belt electric slide 54 is provided on both sides of the closed water tank 50, and the flattening roller 51 moves back and forth on the closed water tank 50 via the synchronous belt electric slide 54. The two ends of the flattening roller 51 are respectively mounted on the sliders of the synchronous belt electric slide 54 through connecting seats. The two synchronous belt electric slides 54 move synchronously, and the flattening roller 51 can maintain horizontal movement.

[0072] The sliders of the two synchronous belt motorized slides 54 are each equipped with a pair of second blowpipes 55, opening toward the horizontal centerline of the enclosed water tank 50. These second blowpipes 55 are symmetrically located on the front and rear sides of the sliders. These second blowpipes 55 are connected to an external high-pressure air source. As the lay-out rollers 51 move back and forth, they partially prop up the rubber sheet, separating it from the enclosed water tank 50. At this point, the second blowpipes 55 blow cool air into the propped-up gap, dissipating the heat in the gap between the rubber sheet and the enclosed water tank 50.

[0073] 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.

[0074] The support frame 58 can be adjusted in position on the enclosed water tank 50 via the slide rails 57, depending on the length of the flattened rubber sheet. The length of the first pressure plate 60 is no greater than the width of the enclosed water tank 50. Guide rods are provided at each end of the first pressure plate 60, and guide holes are provided on the support frame 58 to match the guide rods, ensuring that the first pressure plate 60 remains stable and evenly stressed. To prevent the first pressure plate 60 from sticking to the rubber sheet, a release agent can be sprayed on the bottom of the first pressure plate 60.

[0075] 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.

[0076] The front end of the closed water tank 50 is inclined. This surface, in conjunction with the second pressing plate 62, shortens the travel of the second pressing plate 62. Before use, spray a mold release agent on the bottom of the second pressing plate 62 to prevent adhesion to the rubber sheet and ensure smooth separation of the rubber sheet from the second pressing plate 62 when released.

[0077] The closed water tank 50 is divided into multiple cooling water channels running through the front and back by a group of partitions 66. The rear end of the closed water tank 50 is provided with multiple water inlets corresponding to the cooling water channels, and the front end of the closed water tank 50 is provided with multiple drainage outlets corresponding to the cooling water channels.

[0078] 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 remains flat.

[0079] The structure and working principle of slicer 140:

[0080] The slicer 140 includes a slicing table 70, a second feed roller 71 is provided at the front end of the slicing table 70, an upper pressure roller 72 and a lower pressure roller 73 are provided at the rear end of the slicing table 70, and a cutting blade 74 linked to the lower pressure roller 73 is provided on the slicing table 70 located behind the upper pressure roller 72 and the lower pressure roller 73. A cutting drive motor 75 is provided on one side of the slicing table 70 for driving the cutting blade 74 to move up and down.

[0081] The rubber sheet cooled by the open mill is laid flat on the slicing table 70 through the second feed roller 71 in turn. One end of the rubber sheet is clamped by the upper pressing roller 72 and the lower pressing roller 73. After the cutting drive motor 75 is started, the lower pressing roller 73 and the upper pressing roller 72 cooperate to transport the rubber sheet forward. At the same time, the cutting blade 74 performs an up and down cutting action to cut the passing rubber sheet into strips.

[0082] Slicing table 70 is equipped with support bases 77 on either side, and a slidable blade holder 78 is mounted on each support base. Cutting blade 74 is adjustably mounted on blade holder 78 via a set of screws. Support bases 77 are provided with vertical guide grooves, which guide the ends of blade holder 78, allowing it to maintain vertical movement. Cutting blade 74 is provided with a removable blade holder. One end of the screw is fixed to the blade holder, and blade holder 78 has a set of screw mounting holes. The other end of the screw passes through the screw mounting holes and is adjusted and fixed by a pair of nuts.

[0083] The tops of the two support seats 77 are connected by a rotating shaft 79, on which a pair of eccentric wheels 80 are provided, and on the eccentric wheels 80 a transmission connecting rod 81 for driving the tool holder 78 to move up and down is provided; the two ends of the rotating shaft 79 are respectively provided with a first flywheel 83 and a second flywheel 84, the cutting drive motor 75 drives the first flywheel 83 to rotate through a belt, and the second flywheel 84 drives the lower pressure roller 73 to rotate through a crank connecting rod mechanism 85.

[0084] When the eccentric wheel 80 rotates along with the rotating shaft 79, the driving connecting rod 81 intermittently lifts the knife holder 78 upward, thereby moving the cutting blade 74 up and down to perform the cutting action.

[0085] The crank-connecting rod mechanism 85 in this case includes two cranks respectively connected to the lower pressure roller 73 and the second flywheel 84, and a connecting rod for connecting the two cranks. During the rotation of the second flywheel 84, the crank-connecting rod mechanism 85 drives the lower pressure roller 73 to rotate. Every time the lower pressure roller 73 rotates one circle, it can cooperate with the upper pressure roller 72 to transport the rubber sheet forward a certain distance.

[0086] The second flywheel 84 is provided with a connecting rod adjustment seat 87, and the connecting rod adjustment seat 87 is provided with a screw slide 88. One end of the connecting rod of the crank connecting rod mechanism 85 is rotatably connected to the slider of the screw slide 88. The specific position where the connecting rod of the crank connecting rod mechanism 85 is connected to the second flywheel 84 is adjusted by the screw slide 88, that is, the length of the crank arm connected to the second flywheel 84 is adjusted, thereby adjusting the rotation speed of the lower pressure roller 73. The connecting rod length of the crank connecting rod mechanism 85 is an adjustable connection.

[0087] The connecting rod adjusting seat 87 is provided with a scale ruler corresponding to the screw slide 88. The crank arm length of the crank connected to the second flywheel 84 can be adjusted intuitively and quickly by the scale ruler.

[0088] Upper pressing roller 72 is movably mounted on the support base 77 by a pair of vertical slides 89. The vertical slide 89 of this case is a manual screw slide, which is used to adjust the height of upper pressing roller 72.

[0089] The rear end of the slicing table 70 is provided with a discharging slide 90. It is convenient for the cut film to smoothly slide out from the cutting position.

[0090] A powder box 91 is provided on the slicing table 70 below the second feed roller 71. The second feed roller 71 and the lower pressure roller 73 are both frosted rollers. The top of the powder box 91 is open, and a part of the second feed roller 71 is located in the powder box 91. A material leveling brush 92 is provided on the top of the powder box 91, one end of which abuts against the roller surface of the second feed roller 71.

[0091] When the second feed roller 71 rotates, it will bring out the powder in the powder box 91. The powder is talcum powder. Since the second feed roller 71 is a frosted roller, there are many small grooves on its surface. During the rotation of the second feed roller 71, the material-leveling brush 92 will brush off the excess powder attached to the surface of the second feed roller 71 and spread it evenly, while the powder that falls into the grooves will be retained. The rubber sheet is an elastic product. When passing through the surface of the second feed roller 71, its own weight will cause the powder in the grooves to adhere to the bottom of the rubber sheet. After the rubber sheet is spread flat on the slicing table 70, a layer of powder adheres to the bottom, thereby reducing friction, making it easier for the rubber sheet to move forward smoothly on the slicing table 70 to avoid pulling and deformation.
