Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine technology, specifically to a vulcanizing machine with a dispersion structure. Background Technology

[0002] A vulcanizing machine is a key piece of equipment in rubber product manufacturing, primarily used for the vulcanization and molding of rubber. Its core structure includes a heating device, a pressure system, and a mold cavity. By precisely controlling temperature, pressure, and time, the rubber molecular chains undergo a cross-linking reaction, forming products with specific physical and mechanical properties. Modern vulcanizing machines are often equipped with automated control systems, enabling real-time monitoring and adjustment of parameters, improving production efficiency and product consistency. Based on their structural form, they can be divided into flat vulcanizing machines and injection vulcanizing machines, etc., and are widely used in industries such as tires, seals, and hoses, serving as an important guarantee for the rubber industry to achieve large-scale, standardized production.

[0003] According to a public disclosure (Publication No.: CN221271684U), a vulcanizing machine with a dispersion structure includes: a vulcanizing machine body, a stirring mechanism on one side of the vulcanizing machine body, a sealing mechanism at the top of the vulcanizing machine body, and a base installed at the bottom of the vulcanizing machine body. This utility model uses a rotary motor to drive a rotating rod and a main gear to rotate, causing a first driven gear connected to the main gear to drive a rotating column to rotate, which in turn drives a sleeve block and a stirring plate to rotate synchronously. This stirs the additives and rubber materials inside the device, effectively dispersing the materials and ensuring thorough integration of the additives and rubber materials, thus improving the efficiency of vulcanization production. Simultaneously, a second driven gear connected to the main gear synchronously drives the stirring column to rotate, which in turn drives a crossbar, a stirring brush, and a cleaning brush to rotate, further blending the rubber materials and additives inside the vulcanizing machine body and improving the overall production efficiency of the device.

[0004] However, the above-mentioned applications have problems such as poor dispersion effect and poor cooling effect inside the vulcanizing machine. Therefore, a vulcanizing machine with a dispersion structure is proposed. Utility Model Content

[0005] This invention proposes a vulcanizing machine with a dispersion structure, which solves the problems of poor dispersion effect and poor cooling effect inside the vulcanizing machine in related technologies.

[0006] According to one aspect, at least one embodiment of this disclosure provides a vulcanizing machine with a dispersion structure, comprising: a lower shell, a lower shell cover bolted to the top of the lower shell, an upper shell fixedly connected to the top of the lower shell cover, a support foot pad fixedly connected to the bottom of the lower shell, an upper shell cover snapped onto the top of the upper shell, and a dispersion mechanism disposed inside the upper shell.

[0007] The dispersing mechanism includes a feeding box, the side of which is fixedly connected to the inner wall of the upper shell, a feeding pipe fixedly connected to the bottom of the feeding box, a mixing box fixedly connected to the top of the lower shell cover, a dispersing box fixedly connected to the top of the mixing box, a discharging pipe fixedly connected to the bottom of the dispersing box, a motor fixedly connected to the inner side of the upper shell cover, a rotating shaft fixedly connected to the end of the motor output shaft, a dispersing plate fixedly connected to the circumferential surface of the rotating shaft, a limiting plate fixedly connected to the circumferential surface of the rotating shaft, a mixing plate fixedly connected to the circumferential surface of the rotating shaft, and a cleaning plate fixedly connected to the circumferential surface of the rotating shaft.

[0008] For example, in at least one embodiment of this disclosure, a vulcanizing machine with a dispersed structure is provided, further comprising: a plurality of supporting feet symmetrically arranged along the vertical central axis of the lower shell, which can evenly bear the overall weight of the vulcanizing machine, preventing the equipment from tilting or shifting its center of gravity, ensuring the stability of the equipment during vulcanization, and preventing the vulcanization accuracy from being affected or causing safety hazards due to shaking; the top of the lower shell cover is bolted with screws, a plurality of which are symmetrically arranged along the vertical central axis of the lower shell cover, and the plurality of screws are symmetrically distributed along the vertical central axis of the lower shell cover, and the lower shell cover is fastened to the lower shell by bolt connection to form a rigid connection structure, ensuring stable transmission of internal pressure during vulcanization, and preventing material leakage or equipment damage due to loose connection.

[0009] The number of feeding boxes is set to several and arranged in a circumferential array on the side of the upper shell. The number of feeding pipes is set to several and arranged in a circumferential array at the bottom of the feeding boxes. This allows for the simultaneous dispersion of multiple materials, greatly improving material processing efficiency and avoiding local accumulation or uneven dispersion caused by concentrated feeding.

[0010] The limiting plate has a limiting port on its side, the size of which is larger than the diameter of the discharge pipe. This prevents material from being blocked due to the narrow channel during discharge. At the same time, the material falling speed is adjusted by rotating the limiting plate to ensure that the amount of material entering the mixing tank is uniform and stable, preventing local accumulation or overload. The top of the upper shell cover has several openings arranged in a circular array on the top of the upper shell cover to meet the mixing requirements of multiple components and avoid uneven mixing of different materials at a single inlet.

[0011] The inner side of the mixing tank is sloped, and the rotation radius of the cleaning plate is smaller than the diameter of the mixing tank. The slope design makes the inner wall of the mixing tank narrower at the top and wider at the bottom. Under the action of gravity, the material naturally slides towards the bottom edge, avoiding accumulation in the center of the mixing tank. This ensures that the cleaning plate can effectively grab and mix all the material. Several discharge pipes are arranged in a circumferential array at the bottom of the dispersion box, which can simultaneously transport the uniformly mixed material from multiple points to the vulcanization area of ​​the lower shell. This avoids uneven material flow or deviation caused by a single discharge port, ensures that the amount of material received by the vulcanization extrusion mechanism is consistent, and improves the uniformity of the vulcanized product.

[0012] According to another aspect, at least one embodiment of this disclosure also provides a vulcanizing machine with a dispersion structure, including: a vulcanizing extrusion mechanism, the vulcanizing extrusion mechanism including a half gear, the top of the half gear being fixedly connected to the end of a rotating shaft away from a motor, a slider being slidably connected to the inner wall of a lower shell, a rack being fixedly connected to the side of the slider, a spring being fixedly connected to the side of the rack, the end of the spring away from the rack being fixedly connected to the inner wall of the lower shell, an extrusion plate being fixedly connected to the side of the rack, a template being slidably connected to the inner wall of the lower shell, and a handle being fixedly connected to the side of the template.

[0013] For example, in a vulcanizing machine with a dispersion structure provided in at least one embodiment of this disclosure, the number of springs is set to several and they are symmetrical to each other along the vertical central axis of the rack. One end of each spring is located on the displacement trajectory of the rack, which can ensure that the elastic force applied by the spring is evenly distributed on both sides of the rack, avoiding the rack from tilting, jamming or abnormal wear due to uneven force on one side. The spring can absorb impact energy through compression or stretching, playing a buffering and shock-absorbing role, and avoiding rigid collision damage to parts.

[0014] The width of the half gear is equal to the width of the rack, maximizing the contact area between the two during meshing and avoiding local stress concentration or meshing misalignment caused by inconsistent widths. The width of the extrusion plate is equal to the width of the lower shell, ensuring that the pressure applied by the extrusion plate to the material or mold during vulcanization covers the entire width range of the lower shell, avoiding insufficient edge extrusion or excessive center pressure, and ensuring the uniformity and consistency of the vulcanized product.

[0015] The template has two vertically connected sliders on its side, which are symmetrical about the vertical center axis of the template. They can form a linear guide structure with the groove of the lower shell to ensure that the template moves strictly in a linear direction during linear movement, avoiding tilting or offset caused by unilateral force. The lower shell has a groove on its side, and the width of the slider is equal to the width of the groove to avoid the slider shaking due to excessive gap or jamming due to insufficient gap.

[0016] The side of the template is located on the displacement trajectory of the extrusion plate, ensuring that the axes of the two are aligned during movement. The size of the extrusion plate is smaller than that of the template, which can form a non-pressed area at the edge of the template to accommodate overflowing material or install a sealing structure.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] 1. In this utility model, the mixing box, distributing box and rotating shaft and other components inside the dispersion mechanism cooperate with each other. The circular array of dispersion boxes and dispersion plates perform initial dispersion of materials. After falling into the inclined mixing box through the feed pipe, the mixing plates further cross-mix the materials to ensure uniform composition. The limiting plate can accurately control the feeding speed to avoid blockage. The cleaning plate scrapes off residual materials close to the inner wall of the mixing box, reducing waste and lowering the risk of pollution. The motor drives multiple components to operate synchronously through a single rotating shaft, simplifying the transmission structure, improving coordination efficiency, shortening the material processing cycle, and fully meeting the high requirements of vulcanization process for material pretreatment.

[0019] 2. In this utility model, the mutual cooperation of components such as half gears, racks, and extrusion plates inside the vulcanizing extrusion mechanism achieves efficient and stable vulcanization operations. The half gears mesh with the racks, converting the rotational motion of the shaft into the linear motion of the extrusion plate, simplifying the transmission structure and ensuring stable power output. The springs on the side of the racks have both buffering and reset functions, reducing equipment impact losses and maintaining continuous extrusion cycles. The symmetrically distributed springs ensure smooth movement. The template adopts a sliding bar and groove design, which facilitates material loading and unloading and mold replacement. The width of the extrusion plate is adapted to the lower shell and its size is smaller than that of the template, which can fully extrude materials while avoiding collisions, ensuring the accuracy of vulcanization molding and the quality of finished products.

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5 As shown, it illustrates a vulcanizing machine with a dispersion structure in one embodiment of the present disclosure, including: a lower shell 1, a lower shell cover 2 bolted to the top of the lower shell 1, an upper shell 3 fixedly connected to the top of the lower shell cover 2, a support foot pad 4 fixedly connected to the bottom of the lower shell 1, an upper shell cover 5 snapped onto the top of the upper shell 3, and a dispersion mechanism 6 disposed inside the upper shell 3.

[0032] The dispersing mechanism 6 includes a feed box 61, the side of which is fixedly connected to the inner wall of the upper shell 3. A feed pipe 62 is fixedly connected to the bottom of the feed box 61. A mixing box 63 is fixedly connected to the top of the lower shell cover 2. A dispersing box 611 is fixedly connected to the top of the mixing box 63. A discharge pipe 65 is fixedly connected to the bottom of the dispersing box 611. A motor 66 is fixedly connected to the inner side of the upper shell cover 5. A rotating shaft 67 is fixedly connected to the end of the output shaft of the motor 66. A dispersing plate 68 is fixedly connected to the circumferential surface of the rotating shaft 67. A limiting plate 69 is fixedly connected to the circumferential surface of the rotating shaft 67. A mixing plate 610 is fixedly connected to the circumferential surface of the rotating shaft 67. A cleaning plate 64 is fixedly connected to the circumferential surface of the rotating shaft 67.

[0033] In some examples, the following are also included: a number of support feet 4 are provided, and they are symmetrically arranged along the vertical central axis of the lower shell 1. They can evenly bear the overall weight of the vulcanizing machine, prevent the equipment from tilting or shifting its center of gravity, ensure the stability of the equipment during vulcanization, and prevent the vulcanization accuracy from being affected or the safety hazards caused by shaking. The top of the lower shell cover 2 is bolted with screws, and the number of screws is provided, and they are symmetrically arranged along the vertical central axis of the lower shell cover 2. The screws are symmetrically distributed along the vertical central axis of the lower shell cover 2, and the lower shell cover 2 is fastened to the lower shell 1 by bolt connection to form a rigid connection structure, ensuring stable transmission of internal pressure during vulcanization and preventing material leakage or equipment damage due to loose connection.

[0034] The number of feed boxes 61 is set to several and arranged in a circular array on the side of the upper shell 3. The number of feed pipes 62 is set to several and arranged in a circular array at the bottom of the feed boxes 61. Multiple materials can be dispersed at the same time, which greatly improves the material processing efficiency and avoids local accumulation or uneven distribution caused by concentrated feeding.

[0035] A limiting port is provided on the side of the limiting plate 69. The size of the limiting port is larger than the diameter of the discharge pipe 65, which can prevent the material from being blocked due to the narrow channel during discharge. At the same time, the material falling speed is adjusted by rotating the limiting plate 69 to ensure that the amount of material entering the mixing box 63 is uniform and stable, and to prevent local accumulation or overload. The top of the upper shell cover 5 is provided with a box opening. The number of box openings is set to several and is arranged in a circumferential array on the top of the upper shell cover 5 to meet the mixing needs of multiple components and avoid uneven mixing of different materials at a single inlet.

[0036] The inner side of the mixing tank 63 is sloped, and the rotation radius of the cleaning plate 64 is smaller than the diameter of the mixing tank 63. The slope design makes the inner wall of the mixing tank 63 narrower at the top and wider at the bottom. Under the action of gravity, the material naturally slides to the bottom edge, avoiding accumulation in the center of the mixing tank 63. This ensures that the cleaning plate 64 can effectively grab and mix all the material. There are several discharge pipes 65, which are arranged in a circular array at the bottom of the dispersion box 611. They can simultaneously transport the uniformly mixed material from multiple points to the vulcanization area of ​​the lower shell 1, avoiding uneven material flow or deviation caused by a single discharge port. This ensures that the amount of material received by the vulcanization extrusion mechanism 7 is consistent and improves the uniformity of the vulcanized product.

[0037] For example, such as Figures 1-5 As shown, the worker puts the material into the feeding box 61 through the top opening of the upper cover 5, and it falls into the dispersion box 611 through the feeding pipe 62. The worker drives the motor 66 to start, and the motor 66 drives the rotating shaft 67, which drives the dispersion plate 68 to disperse the material at high speed in the dispersion box 611. The limiting plate 69 controls the falling speed of the material, and then it enters the mixing box 63 through the discharge pipe 65. The rotating shaft 67 drives the mixing plate 610 to rotate, and the mixing plate 610 further mixes the material in the mixing box 63. The cleaning plate 64 scrapes off the residue on the inner wall.

[0038] like Figures 1-5 As shown, it illustrates a vulcanizing machine with a dispersion structure in another embodiment of this disclosure, which is largely the same as the above-described technical solution. Therefore, only the differences are described in detail. It includes: a vulcanizing extrusion mechanism 7, which includes a half gear 71. The top of the half gear 71 is fixedly connected to the end of the rotating shaft 67 away from the motor 66. A slider 72 is slidably connected to the inner wall of the lower shell 1. A rack 73 is fixedly connected to the side of the slider 72. A spring 74 is fixedly connected to the side of the rack 73. The end of the spring 74 away from the rack 73 is fixedly connected to the inner wall of the lower shell 1. An extrusion plate 75 is fixedly connected to the side of the rack 73. A template 76 is slidably connected to the inner wall of the lower shell 1. A handle 77 is fixedly connected to the side of the template 76.

[0039] In some examples, the springs 74 are arranged in a number that are symmetrical about each other along the vertical central axis of the rack 73. One end of the spring 74 is located on the displacement trajectory of the rack 73, which can ensure that the elastic force applied by the spring 74 is evenly distributed on both sides of the rack 73, avoiding the rack 73 from tilting, jamming or abnormal wear due to uneven force on one side. The spring 74 can absorb impact energy through compression or stretching, playing a buffering and shock absorption role, and avoiding rigid collision damage to components.

[0040] The width of the half gear 71 is equal to the width of the rack 73, which maximizes the contact area between the two during meshing and avoids local stress concentration or meshing misalignment caused by inconsistent widths. The width of the extrusion plate 75 is equal to the width of the lower shell 1, which ensures that the pressure applied by the extrusion plate 75 to the material or mold during vulcanization covers the entire width range of the lower shell 1, avoiding insufficient edge extrusion or excessive center pressure, and ensuring the uniformity and consistency of the vulcanized product.

[0041] The template 76 is fixedly connected to a slider on its side. There are two vertical sliders, which are symmetrical about each other along the vertical central axis of the template 76. They can form a linear guide structure with the groove of the lower shell 1 to ensure that the template 76 moves strictly in the linear direction during linear movement and avoid tilting or offset caused by unilateral force. The lower shell 1 has a groove on its side. The width of the slider 72 is equal to the width of the groove to avoid the slider 72 shaking due to excessive gap or jamming due to insufficient gap.

[0042] The side of the template 76 is located on the displacement trajectory of the extrusion plate 75, ensuring that the two are aligned on the axis during movement. The size of the extrusion plate 75 is smaller than that of the template 76, which can form a non-pressed area at the edge of the template 76 to accommodate overflowing material or install a sealing structure.

[0043] For example, such as Figures 1-5 As shown, motor 66 drives shaft 67 to rotate, and half gear 71 at one end of shaft 67 rotates accordingly. When it meshes with rack 73, it pushes rack 73 to move horizontally. Rack 73 slides in the groove through slider 72, driving extrusion plate 75 to move towards template 76 and apply pressure to the material. When half gear 71 disengages, springs 74 symmetrically distributed along the vertical central axis of rack 73 provide a restoring force, pulling rack 73 to drive extrusion plate 75 to reset, realizing intermittent extrusion, so that the material completes vulcanization molding in template 76. Subsequently, the operator uses handle 77 to pull template 76 away under the action of slider and removes the extruded material.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
