Technical Field

[0002] An open mixing mill, also known as an open mill, is a rubber mixing machine with exposed rollers used in rubber factories to prepare plasticized rubber, mixed rubber, or perform hot refining and molding. Its function is to mix and plasticize the uniformly mixed raw materials. Flexible rubber and plastic foam products are made by mixing the raw materials of the product formula, cutting them into sheets, plasticizing and extruding them through an extruder, and foaming them at a suitable temperature in a foaming furnace to obtain the finished product.

[0058] Furthermore, the first driving gear 21 is an incomplete gear, and the first driving gear 21 meshes with the first driven gear 22 to form an intermittent meshing transmission.

[0059] Furthermore, the first driving bevel gear 65 has more teeth than the first driven bevel gear 66.

[0060] The following, in conjunction with the accompanying drawings, further elaborates on the usage method and principle of the technical solution in this specific embodiment:

[0061] During the preparation work for film production, the first motor 25 is started. The power output shaft of the first motor 25 rotates, driving the first transmission shaft 2, which is axially connected to it, to rotate. The rotation of the first transmission shaft 2 drives the first drive gear 21, which is concentrically mounted with it, to rotate. The rotation of the first drive gear 21 drives the first driven gear 22, which meshes with it, to rotate. The rotation of the first driven gear 22 then drives the second transmission shaft 23, which is concentric with it, to rotate. The rotation of the second transmission shaft 23 drives the first drive pulley 24, which is concentric with it, to rotate. The rotation of the first drive pulley 24 can then drive the first driven pulley 61 to rotate through the plate chain conveyor belt 27, forming a plate chain conveyor structure, which can transport the raw film in the guide trough 11.

[0062] Meanwhile, the first driving gear 21 is an incomplete gear. When the first driving gear 21 rotates and the teeth of the first driving gear 21 mesh with the first driven gear 22, the first driven gear 22 can rotate, which in turn causes the second transmission shaft 23 to rotate. The rotation of the second transmission shaft 23 drives the first driving pulley 24 to rotate, which in turn causes the first driving pulley 24 to drive the plate chain conveyor belt 27 to transport the raw material film.

[0063] When the first driving gear 21 rotates and the teeth of the first driving gear 21 do not mesh with the first driven gear 22, the first driven gear 22 stops rotating, which in turn causes the second transmission shaft 23 to stop rotating. The second transmission shaft 23 stops rotating, which causes the first driving pulley 24 to stop rotating, which in turn causes the plate chain conveyor belt 27 to stop conveying the raw material film.

[0064] The fact that the first driving gear 21 is an incomplete gear allows the plate chain conveyor belt 27 to move intermittently when conveying the raw material film, thus allowing time for the cutting assembly to cut the raw material film.

[0065] Simultaneously, when the first drive shaft 2 rotates, the second drive pulley 26, which is concentrically mounted with it, rotates. The rotation of the second drive pulley 26 drives the second driven pulley 4 to rotate via the first drive belt 28. The rotation of the second driven pulley 4 drives the third drive shaft 41 to rotate. The rotation of the third drive shaft 41 drives the first connecting rod 42 to rotate. The rotation of the first connecting rod 42 then drives the second connecting block 43 to rotate. Since the position of the first connecting block 45 is fixed, when the first connecting rod 42 drives the second connecting block 43 to rotate, the second sliding plate 46 will reciprocate up and down around the first connecting block 45. This causes the second connecting rod 47 to drive the first mounting plate 471 to reciprocate up and down. The reciprocating up and down movement of the first mounting plate 471 then drives the T-shaped sliding rod 48 to reciprocate up and down within the T-shaped groove 36 on the second mounting plate 32 via the third connecting shaft 472. This achieves the purpose of cutting the raw material film with the cutting knife 49.

[0066] The T-shaped groove 36 on the first sliding plate 35 can change the reciprocating swing of the second sliding plate 46 into a reciprocating up-down movement, thus limiting the direction of movement.

[0067] Meanwhile, the second sliding plate 46 is provided with a first sliding groove 461, which can provide stroke for the up and down reciprocating motion of the cutting blade 49. When the first connecting rod 42 rotates, the second sliding plate 46 has two extreme positions when it reciprocates, so that the first connecting rod 42 has an extreme position angle. This makes the cutting blade 49 have a quick return characteristic when cutting the raw material film, which can accelerate the cutting speed of the cutting blade 49 and thus better complete the cutting of the raw material film.

[0068] When the first driven pulley 61 rotates under the drive of the plate chain conveyor belt 27, the fourth transmission shaft 6, which is concentric with the first driven pulley 61, rotates, thereby driving the second driving gear 62 to rotate. The rotation of the second driving gear 62 drives the second driven gear 63, which meshes with it, to rotate. The rotation of the second driven gear 63 drives the fifth transmission shaft 64, which is concentric with it, to rotate. The rotation of the fifth transmission shaft 64 drives the first driving bevel gear 65, which is concentric with it, to rotate. The rotation of the first driving bevel gear 65 drives the first driven bevel gear 66, which meshes with it, to rotate. The rotation of the moving bevel gear 66 drives the sixth transmission shaft 67 to rotate, which in turn drives the rotating disk 68 to rotate. The rotation of the rotating disk 68 drives the third connecting rod 69 on its top end face to drive the drive plate 7 to reciprocate along the limiting slide groove 53 opened on the fourth mounting plate 51. The reciprocating motion of the drive plate 7 drives the push plate 74 installed at its bottom to reciprocate, so as to push the cut film material onto the belt scale. The inlet of the belt scale is connected to the baffle 54, which facilitates the pushing of the film material.

[0069] Then the film raw material is pushed onto belt scale B for weighing, then inspected by inspection scale C, and finally transported to open mill D for rubber mixing, and assisted in rubber mixing by moving trolley E.

[0070] Meanwhile, the number of teeth of the first driving bevel gear 65 is greater than that of the first driven bevel gear 66. Since the movement of the plate chain conveyor belt 27 is intermittent, when the plate chain conveyor belt 27 drives the first driven pulley 61 to rotate intermittently once, the first driving bevel gear 65 can drive the first driven bevel gear 66 to complete a complete rotation, thereby enabling the glue pushing assembly to complete a glue pushing action, so that the entire glue pushing action remains continuous.

[0071] The limit plate 72 is provided at the bottom of the drive plate 7 to keep it vertical when the push plate 74 pushes the film material so that the film material can be pushed onto the belt scale. At the same time, when the push plate 74 retracts, it can prevent the retracted push plate 74 from being blocked by the replenished film material, thus ensuring the stability of pushing the film material.

[0072] The second plate chain through hole 55 and the first plate chain through hole 31 facilitate the movement of the plate chain conveyor belt 27. At the same time, the top of the first box 3 is in contact with the bottom of the plate chain conveyor belt 27, which can provide some support when the rubber cutting knife 49 cuts the film material.

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
