Description

Technical Field

[0001] The invention relates to the field of rubber hanging ring manufacturing, in particular to a kneading machine for manufacturing rubber hanging rings. Background Art

[0002] Rubber lifting rings are usually used in industries such as industry, construction, and lifting for lifting, connection, and other purposes. A kneading mill is required for manufacturing. During operation, the two rotors rotate relative to each other, clamping the material from the feeding port and bringing it into the roller gap, so that it is squeezed and sheared by the rotors. After passing through the roller gap, the material hits the sharp edge of the lower top bolt and is divided into two parts, which return to the top of the roller gap along the gap between the front and rear chamber walls and the rotor. During one cycle of flowing around the rotor, the material is sheared and rubbed everywhere, causing the temperature of the rubber to rise sharply, the viscosity to decrease, and the wettability of the rubber on the surface of the compound to increase, so that the rubber and the surface of the compound are fully in contact. At the same time, the ridges on the rotor cause the rubber to move along the axial direction of the rotor, which plays a stirring and mixing role, so that the compound is evenly mixed in the rubber;

[0003] For example, the Chinese utility model patent with publication number CN221540435U discloses a rubber kneading machine, which discloses a technical solution that controls the shell to flip by a first hydraulic cylinder to facilitate unloading, and is supplemented by a support sleeve, a support rod and a spring so that the shell can be stably rotated to a horizontal state or conveniently rotated to an inclined state. However, the defects thereof are as follows:

[0004] 1. When the shell is flipped to horizontal hovering, the support sleeve, support rod and spring provide additional elastic support for the shell to improve the stability of the shell when it is horizontally hovering. However, the vibration generated during the operation of the equipment will inevitably cause the spring to jump and fail to provide stable support for the shell, affecting the stability of the shell in the horizontal hovering state;

[0005] 2. The blades on each rotating shaft will stick to the material, making it inconvenient to clean. Summary of the invention

[0006] The present invention aims to solve one of the technical problems existing in the prior art.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0052] The kneading machine for manufacturing rubber hanging rings provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0053] Embodiment 1:

[0054] like Figures 1 to 4As shown, the embodiment of the present application provides a kneading machine for manufacturing rubber rings, including a casing 1 with one side open, a lifting cover plate 2, a material holding shell 3, a turning device 4 and a pair of kneading rollers 5, the turning device 4 includes a notch 41, which is arranged at the top rear end of the casing 1; a hydraulic cylinder 42, which is rotatably installed in the notch 41 through a turning frame, and the piston end is movably connected to the casing 1; a plurality of convex shells 43, symmetrically arranged on the two end surfaces of the material holding shell 3, for rotatably installing each kneading roller 5; a pair of L-grooves 44, symmetrically arranged on a pair of side walls of the casing 1, and slidably connected to each convex shell 43; a locking mechanism 45, installed on one side wall of the casing 1, drivingly connected to the piston end of the hydraulic cylinder 42, and detachably connected to the adjacent side wall of the casing.

[0055] Furthermore, the locking mechanism 45 includes a plurality of locking grooves 451, which are arranged on the inner side wall of the housing 1; a rotating shell 452, which is rotatably mounted on the outer side of the convex shell 43 close to the hydraulic cylinder 42, and is drivingly connected to the piston end of the hydraulic cylinder 42 through a linkage mechanism 6; a plurality of flip blocks 453, which are drivingly connected to the rotating shell 452 through a linkage member 7, one end of which is hinged on the side wall of the material holding shell 3, and the other end of which can be inserted into the corresponding locking groove 451;

[0056] Furthermore, the linkage mechanism 6 includes an extension section 61, which extends from the bottom of one side of the material holding shell 3 to the inner end of the casing 1; a slide groove 62, which is arranged in the extension section 61; a slider 63, which is slidably installed in the slide groove 62 and is hinged to the piston end of the hydraulic cylinder 42; a reset groove 64, which is arranged at the end of the slide groove 62 away from the hydraulic cylinder 42; a floating rod 65, which is slidably installed in the reset groove 64 and the slide groove 62, and a floating spring is provided between the inner end of the slide groove 62, and one side of the top extends out of the reset groove 64, and is connected to the semicircular rotating shell 452 through a swing arm 66.

[0057] Furthermore, the linkage member 7 includes a transmission arc groove 71, which is arranged on one of the semicircular rotating shells 452; a push arc bar 72, which is arranged on the inner arc surface of the transmission arc groove 71 and has an inclined push surface 74 facing the corresponding flip block 453 end; and an inclined notch 73, which is arranged on the bottom surface of the flip block 453 away from the hinged end.

[0058] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when it is necessary to tilt the opening of the material holding shell 3 toward the outside of the casing 1 for unloading, the hydraulic cylinder 42 is actuated, the piston rod is retracted, and the piston rod is equipped with a pulling slider 63 to abut against the end of the slide groove 62 away from the reset groove 64. The floating spring pushes the floating rod 65 to go deep into the reset groove 64. The floating rod 65 pulls the semicircular rotating shell 452 to rotate through the swing arm 66, so that each push arc bar 72 is separated from the corresponding flip block 453. Each flip block 453 is movably installed on the side wall of the material holding shell 3 through a hinge shaft and a bracket. A torsion spring is provided on the hinge shaft. At this time, the torsion spring releases its elastic potential energy, so that each flip block 453 is separated from the corresponding lock groove 451. Then the hydraulic cylinder 42 continues to act, pulling the material holding shell 3 to move into the casing 1, and each convex shell 43 slides into the upright section at the inner end of the L groove 44 in turn, so that the opening of the material holding shell 3 is tilted toward the outside of the casing 1 to a horizontal state. When the material holding shell 3 is flipped to the open side facing upward, the hydraulic cylinder 42 is actuated, the piston rod is extended, the floating spring remains in an extended state, and each shell slides toward the outer end of the horizontal section of the L groove 44 in turn until one of the convex shells 43 is tightly against the outer end of the horizontal section of the L groove 44, and the piston rod of the hydraulic cylinder 42 continues to extend, pushing the slider 63 and the floating rod 65 to slide toward the reset groove 64, and the floating spring is compressed and shortened, and pushes the semicircular rotating shell 452 to rotate through the swing arm 66, and each push arc bar 72 moves toward the corresponding flip block 453, and the inclined push surface 74 cooperates with the inclined notch 73 to push each flip block 453 to flip around the hinge shaft until each flip block 453 is away from the hinge shaft end and engages with the corresponding lock groove 451. At this time, the side wall of each flip block 453 with the inclined notch 73 is in contact with the outer peripheral wall of each push arc bar 72, and the corresponding torsion spring is deformed to store elastic potential energy, thereby completing the fixation of the material holding shell 3.

[0059] Embodiment 2:

[0060] like Figure 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes a plurality of blades 8, which are telescopically mounted on the peripheral wall of each kneading roller 5 through corresponding notches 9; a pair of telescopic control devices 10, which are mounted in the inner cavity of each kneading roller 5 and are transmission-connected to the corresponding blades 8 for controlling the telescopic movement of each blade 8; and a trigger member 11, which is mounted at the rear end of the L-groove 44 on one side and is used to control the action of the pair of telescopic control devices 10.

[0061] Furthermore, the telescopic control device 10 includes a telescopic rod 101, which is floatingly installed in the inner cavity of the kneading roller 5, one end of which is provided with a telescopic control spring 102, and the other end extends out of the kneading roller 5; a transverse groove 103, which passes through the peripheral wall of the telescopic rod 101 on the left and right, and a plurality of V-shaped grooves 104 are provided inside at intervals; a plurality of guide blocks 105, which are respectively fixed at the inner end of each blade 8 and slidably cooperate with the corresponding V-shaped groove 104.

[0062] Furthermore, the telescopic control device 10 further includes a convex ring 106 , which is fixedly disposed at the inner end of the telescopic rod 101 and abuts against the end of the telescopic control spring 102 .

[0063] Furthermore, the trigger member 11 includes a trigger cover 111 , which is fixed on the outer side wall of the housing 1 , the cover is arranged outside the inner end of the L groove 44 , and is open away from the end of the hydraulic cylinder 42 ; a guide slope 112 , which is arranged on the inner side wall of the open end of the trigger cover 111 .

[0064] In this embodiment of the present application, due to the adoption of the above-mentioned structure, during the movement of each convex shell 43 toward the vertical section at the inner end of the L-groove 44, each telescopic rod 101 approaches and the outer end cooperates with the guiding inclined surface 112 on the trigger cover 111. When each convex shell 43 enters the vertical section at the inner end of the L-groove 44, each telescopic rod 101 is also pushed into the corresponding kneading roller 5, and each V-shaped groove 104 and each telescopic rod 101 move simultaneously, so that each guide block moves toward the bent end of the V-shaped groove 104, pulling each blade 8 into the corresponding notch 9, and the telescopic control The control spring 102 is compressed and shortened. At this time, the surface of each kneading roller 5 becomes smooth, and the materials adhering to each blade 8 are also scraped off, which is convenient for workers to clean up. When each convex shell 43 moves to the horizontal section at the outer end of the L groove 44, until each telescopic rod 101 is separated from the trigger cover 111, the telescopic control spring 102 releases its elastic potential energy, pushing each telescopic rod 101 to slide outside the kneading roller 5, and each guide block moves to the end of the corresponding V-shaped groove 104, pushing each blade 8 to extend out of the corresponding notch 9. At this time, the material holding shell 3 is also turned over to be open upward.

[0065] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
