Description

Technical Field

[0001] The present invention relates to the field of rubber sling manufacturing, and particularly relates to a kneader for rubber sling manufacturing. Background Art

[0002] Rubber slings are usually used in industrial, construction, lifting and other fields for lifting, connecting and other functions. When manufacturing, a kneader is required. During operation, two rotors rotate relatively, clamping the material from the feeding port and bringing it into the roll gap, so that it is subjected to the extrusion and shear of the rotors. After passing through the roll gap, the material hits the sharp edge of the lower plug and is divided into two parts, which respectively return to the upper part of the roll gap along the gaps between the front and rear chamber walls and the rotors. During one week of flowing around the rotors, the material is everywhere subjected to shear and friction, causing the temperature of the rubber compound to rise sharply and the viscosity to decrease, increasing the wettability of the rubber on the surface of the compounding agent and enabling the rubber to be in full contact with the surface of the compounding agent. At the same time, the convex ridges on the rotors cause the rubber compound to move axially along the rotors, playing a role of stirring and mixing, so that the compounding agent is evenly mixed in the rubber compound;

[0003] For example, a Chinese utility model patent with the publication number of CN221540435U for a rubber kneader discloses a technical solution in which a housing is controlled to be flipped by a first hydraulic cylinder for convenient discharging, and a support sleeve, a support rod and a spring are supplemented to enable the housing to be stably rotated to a horizontal state and also to be conveniently rotated to an inclined state. However, its existing defects are:

[0004] 1. When the housing is flipped to a horizontal hover, an additional elastic support force is provided for the housing through the support sleeve, the support rod and the spring to improve the stability of the housing during horizontal hovering. However, the vibration generated during the operation of the equipment will inevitably cause the spring to jump, unable to provide stable support for the housing, affecting the stability of the housing in the horizontal hovering state;

[0005] 2. The blades on each rotating shaft will adhere to the material, which is not convenient for cleaning. Summary of the Invention

[0052] Next, in conjunction with the accompanying drawings, the kneader for manufacturing rubber lifting rings provided in the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0053] Embodiment 1:

[0054] As Figures 1 to 4As shown in the figure, the embodiment of the present application provides a kneader for manufacturing rubber rings, which includes a housing 1 with an open side, a lifting cover plate 2, a material receiving housing 3, a flipping device 4, and a pair of kneading rollers 5. The flipping device 4 includes a notch 41 provided at the rear end of the top of the housing 1; a hydraulic cylinder 42 rotatably installed in the notch 41 through a flipping frame, and the piston end is movably connected to the housing 1; a plurality of convex shells 43 symmetrically arranged on both end faces of the material receiving housing 3 for rotatably installing each kneading roller 5; a pair of L-shaped grooves 44 symmetrically arranged on the opposite side walls of the housing 1 and slidably connected to each convex shell 43; a locking mechanism 45 installed on one side wall of the housing 1 and drivingly connected to the piston end of the hydraulic cylinder 42 for detachably connecting to the adjacent side wall of the housing.

[0055] Further, the locking mechanism 45 includes a plurality of locking grooves 451 provided on the inner side wall of the housing 1; a rotating shell 452 rotatably installed outside the convex shell 43 close to the side of the hydraulic cylinder 42 and drivingly connected to the piston end of the hydraulic cylinder 42 through a linkage mechanism 6; a plurality of flipping blocks 453 drivingly connected to the rotating shell 452 through a linkage member 7, with one end hinged to the side wall of the material receiving housing 3 and the other end insertable into the corresponding locking groove 451.

[0056] Further, the linkage mechanism 6 includes an extension section 61 extending from the bottom of one side of the material receiving housing 3 towards the inner end of the housing 1; a sliding groove 62 provided in the extension section 61; a slider 63 slidably installed in the sliding groove 62 and hinged to the piston end of the hydraulic cylinder 42; a reset groove 64 provided at the end of the sliding groove 62 away from the hydraulic cylinder 42; a floating rod 65 slidably installed in the reset groove 64 and the sliding groove 62, with a floating spring provided between the floating rod 65 and the inner end of the sliding groove 62, and the top side of the floating rod 65 extending out of the reset groove 64 and drivingly connected to the rotating shell 452 through a swing arm 66.

[0057] Further, the linkage member 7 includes a transmission arc groove 71 provided on one of the rotating shells 452; a pushing arc bar 72 provided on the inner arc surface of the transmission arc groove 71, with an inclined pushing surface 74 provided at the end towards the corresponding flipping block 453; an inclined notch 73 provided on the bottom surface of the flipping 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, and the floating spring pushes the floating rod 65 to go deep into the reset groove 64. The floating rod 65 pulls the 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, and 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, and 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 to 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, the floating spring is compressed and shortened, and pushes the rotating shell 452 to rotate through the swing arm 66, and each push arc strip 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 strip 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] Further, the telescopic control device 10 further includes a convex ring 106, which is fixedly arranged at the inner end of the telescopic rod 101 and abuts against the end of the telescopic control spring 102.

[0063] Further, the trigger member 11 includes a trigger cover 111, which is fixedly arranged on the outer side wall of the casing 1, covers the outer end of the inner end of the L-shaped groove 44, and is open at the end away from the hydraulic cylinder 42; a guiding inclined surface 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 above structure, during the process of each convex shell 43 moving towards the vertical section at the inner end of the L-shaped 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-shaped groove 44, each telescopic rod 101 is also pushed into the corresponding kneading roller 5. Each V-shaped groove 104 and each telescopic rod 101 move simultaneously, causing each guiding block to move towards the bent end of the V-shaped groove 104, pulling each blade 8 to retract into the corresponding notch 9, and the telescopic control spring 102 is compressed and shortened. At this time, the surfaces of each kneading roller 5 are smooth, and the materials adhered to each blade 8 are also scraped off, facilitating cleaning by workers. When each convex shell 43 moves towards the horizontal section at the outer end of the L-shaped groove 44 until each telescopic rod 101 disengages from the trigger cover 111, the telescopic control spring 102 releases its elastic potential energy, pushing each telescopic rod 101 to slide outward from the kneading roller 5, each guiding block moves towards the end of the corresponding V-shaped groove 104, and pushes each blade 8 to extend out of the corresponding notch 9. At this time, the material housing 3 also flips to have the opening facing upward.

[0065] It should be noted that in this article, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of other identical elements in the process, method, article or device including that element.
