[0003] According to a public disclosure (Publication No.: CN220741847U), a multi-layer rubber vulcanizing machine includes: a base plate and a top plate, with their sides fixedly connected by frames; between the base plate and the top plate, arranged sequentially from bottom to top, are a lower heating plate, several middle heating plates, and an upper heating plate; a lower template is fixed to the upper end of the lower heating plate; upper and lower templates are respectively installed at the lower and upper ends of the middle heating plates; and an upper template is fixed to the lower end of the upper heating plate; two track plates are arranged between the base plate and the top plate, with slides fixed to the lower ends of the track plates, the slides slidingly engaging with the base plate or top plate; radially distributed track grooves are provided on the track plates, with guide pillars slidingly fitted within the track grooves, and the two ends of the guide pillars fixedly connected to the corresponding lower heating plate, middle heating plate, or upper heating plate via connecting rods; the machine also includes a drive structure for driving the track plates closer together or further apart. This multi-layer rubber vulcanizing machine has the advantages of stable structure, synchronous mold opening and closing, and high efficiency.

[0004] However, the above-mentioned applications have problems such as poor heat dissipation effect inside the vulcanizing machine and poor gap function of the vulcanizing machine. Therefore, a multi-layer rubber vulcanizing machine is proposed. Utility Model Content

[0005] This invention proposes a multi-layer rubber vulcanizing machine, which solves the problems of poor heat dissipation inside the vulcanizing machine and poor gap function in related technologies.

[0006] According to one aspect, at least one embodiment of this disclosure provides a multi-layer rubber vulcanizing machine, comprising: a machine body, a support foot pad fixedly connected to the bottom of the machine body, a hinge shaft fixedly connected to the side of the machine body, a sealing door rotatably connected to the circumferential surface of the hinge shaft, a handle fixedly connected to the side of the sealing door, a control panel provided on the side of the machine body, a pressure gauge provided on the side of the machine body, and a water mist spraying mechanism provided inside the machine body;

[0007] The water mist spraying mechanism includes a water tank, the bottom of which is fixedly connected to the inner wall of the machine body, and a water inlet pipe fixedly connected to the top of the water tank. A motor is bolted to the inner wall of the machine body, and a half gear is fixedly connected to the end of the motor output shaft. A slider is slidably connected to the inner wall of the machine body, and a rack is fixedly connected to the side of the slider. The rack meshes with the half gear. A connecting plate is fixedly connected to the side of the rack, and a U-shaped plate is fixedly connected to the top of the connecting plate. A water supply plate is fixedly connected to the side of the U-shaped plate. A spring is fixedly connected to the bottom of the rack, and the end of the spring away from the rack is fixedly connected to the inner wall of the machine body. A water mist nozzle is fixedly connected to the side of the water tank.

[0008] For example, in at least one embodiment of the present disclosure of a multi-layer rubber vulcanizing machine, the following is further provided: the number of supporting foot pads is set to several and is symmetrical to each other along the vertical central axis of the machine body, which can evenly distribute the overall weight of the equipment to the ground and avoid tilting or vibration caused by the shift of the center of gravity; the number of springs is set to two and is symmetrical to each other along the vertical central axis of the rack; the half gear and the rack meshing section push the rack to slide upward, which can ensure that the rack is evenly stressed during the movement, prevent the rack from tilting or misaligning with the half gear due to excessive tension on one side, avoid jamming, and ensure the stability and reliability of the transmission mechanism.

[0009] The hinge shafts are arranged in a linear array along the inner wall of the machine body, which can distribute the weight of the sealing door and the torque during opening and closing to multiple connection points, avoiding deformation or breakage of a single hinge bearing due to excessive load, and improving the reliability of the connection between the sealing door and the machine body. The machine body has several heat dissipation vents arranged in a linear array along the side of the machine body. The evenly distributed heat dissipation vents can prevent temperature dead zones inside the machine body, ensure the uniformity of the temperature field in the vulcanization chamber, and avoid over-vulcanization or under-vulcanization of rubber products due to local overheating. The water mist nozzles are arranged in a linear array along the side of the water tank, which can make the water mist cover the internal space of the vulcanization chamber in a surface, avoiding local over-wetting or spray blind spots caused by traditional single-point spraying.

[0010] The side of the water tank is provided with a sliding groove, and the number of sliding grooves is set to a certain extent and arranged in a linear array on the side of the water tank. The side of the connecting plate is fixedly connected with a sliding strip, the width of which is equal to the width of the sliding groove, providing rigid guidance in the linear direction to ensure that it moves in a straight line along a fixed path under the drive of the motor, and avoids deviation or jamming due to uneven force.

[0011] One end of the spring is located on the displacement trajectory of the rack, ensuring that the rack can be forcibly reset along a preset path by the spring force after the half gear disengages, avoiding incomplete reset due to inertia or friction, and ensuring the periodic accuracy of the reciprocating motion. The width of the rack is equal to the width of the half gear, ensuring that the tooth surfaces of the two are in complete contact when meshing, avoiding local load concentration or meshing misalignment caused by width difference, maximizing the transmission of driving force, and reducing slippage or wear. The half gear has spokes on its side, and the number of spokes is set to several and arranged circumferentially on the side of the half gear, distributing the stress of the half gear body and the shaft hole connection area to multiple spokes, avoiding gear deformation or breakage due to unilateral meshing force.

[0012] According to another aspect, at least one embodiment of this disclosure also provides a multi-layer rubber vulcanizing machine, comprising: a vulcanizing compression mechanism, the vulcanizing compression mechanism including a slide shaft, one end of the slide shaft being fixedly connected to the inner wall of the machine body, a hollow block being slidably connected to the circumferential surface of the slide shaft, a template being fixedly connected to the circumferential surface of the hollow block, an extrusion block being fixedly connected to the bottom of the template, a return spring being fixedly connected to the bottom of the hollow block, a fixing plate being fixedly connected to the other end of the slide shaft, a hydraulic tank being fixedly connected to the inner wall of the fixing plate, a hydraulic rod being slidably connected to the bottom of the hydraulic tank, a hydraulic plate being fixedly connected to one end of the hydraulic rod, an L-shaped plate being fixedly connected to the side of the U-shaped plate, and a hydraulic plate being fixedly connected to the side of the L-shaped plate.

[0013] For example, in at least one embodiment of this disclosure, a multi-layer rubber vulcanizing machine is provided, which further includes: a plurality of sliding shafts arranged in a circumferential array on the inner wall of the machine body to form a three-dimensional symmetrical support structure, which evenly distributes the pressure generated by the hydraulic system during vulcanization to the inner wall of the machine body in all directions, avoiding deformation or cracking of the machine body caused by single-point force; and a plurality of hollow blocks arranged in a linear array on the circumferential surface of the sliding shafts, which enables the vulcanizing machine to process multi-layer rubber raw materials at the same time, greatly improving production efficiency.

[0014] The number of return springs is set to several and arranged in a linear array on the circumference of the slide shaft to ensure uniform force distribution along the axial direction, avoid overload of a single return spring, and improve the reliability of the mechanism. One end of the return spring is located on the displacement trajectory of the hollow block. The return spring can limit the maximum displacement of the hollow block, provide buffering at the end of the movement, and reduce impact noise and mechanical wear.

[0015] The template and extrusion block are arranged in a number of units, and are arranged in a linear array on the circumference of the slide shaft. The parallel distribution of multiple components can realize multi-station synchronous operation and improve efficiency. The size of the mold hole on the side of the template is larger than the size of the extrusion block. The size difference is used to form an extrusion gap. Pressure is applied to the material through relative motion to realize the molding operation.

[0016] The top of the extrusion block is located on the displacement trajectory of the first hydraulic plate, ensuring that the hydraulic pressure is converted into mechanical pressure without deviation, pushing the extrusion block into the mold hole of the template. The dimensions of the first and second hydraulic plates are equal to the inner wall size of the hydraulic tank, ensuring that there is no lateral leakage of hydraulic pressure when it is pressurized, and the pressure loss is close to zero.

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

[0018] 1. This utility model achieves precise control of the vulcanization environment through the coordinated operation of components such as half-gears, racks, and U-shaped plates within the water mist spraying mechanism. The motor drives the half-gears and racks, which, under the action of spring reset, drive the nozzles in reciprocating linear motion. Combined with the linear array nozzle layout, this allows for full coverage and uniform water mist spraying of the vulcanization chamber. The sliding grooves on the side of the water tank and the guide rails on the connecting plate ensure stable movement. This mechanism effectively regulates vulcanization humidity, assisting in the molding of rubber products, and also helps cool the equipment through periodic spraying, preventing localized overheating. Furthermore, its compact structure and convenient maintenance significantly improve the stability of the vulcanization process and product quality.

[0019] 2. In this utility model, the cooperation of components such as the template, hydraulic tank, and L-shaped plate inside the vulcanizing compression mechanism effectively ensures the quality and efficiency of rubber vulcanization. The circumferential array of sliding shafts provides stable support, and together with the linear array of hollow blocks, templates, and extrusion blocks, multi-layer rubber vulcanization is achieved simultaneously, significantly improving production efficiency. Precise matching between the hydraulic plate and the hydraulic tank ensures efficient and uniform pressure transmission, and the dimensional difference between the extrusion block and the template die hole ensures thorough rubber compaction. A return spring ensures accurate mechanism reset, and the coordinated operation of all components guarantees stable vulcanization pressure while improving equipment reliability and product precision.

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. 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.

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 1-5As shown, a multi-layer rubber vulcanizing machine according to an embodiment of the present disclosure is illustrated, comprising: a machine body 1, a support foot pad 2 fixedly connected to the bottom of the machine body 1, a hinge shaft 3 fixedly connected to the side of the machine body 1, a sealing door 4 rotatably connected to the circumferential surface of the hinge shaft 3, a handle 5 fixedly connected to the side of the sealing door 4, a control panel 6 provided on the side of the machine body 1, a pressure gauge 7 provided on the side of the machine body 1, and a water mist spraying mechanism 8 provided inside the machine body 1.

[0032] The water mist spraying mechanism 8 includes a water tank 81, the bottom of which is fixedly connected to the inner wall of the body 1, and a water inlet pipe 82 fixedly connected to the top of the water tank 81. A motor 83 is bolted to the inner wall of the body 1, and a half gear 84 is fixedly connected to the end of the output shaft of the motor 83. A slider 85 is slidably connected to the inner wall of the body 1, and a rack 86 is fixedly connected to the side of the slider 85. The rack 86 meshes with the half gear 84. A connecting plate 87 is fixedly connected to the side of the rack 86, and a U-shaped plate 88 is fixedly connected to the top of the connecting plate 87. A water supply plate 89 is fixedly connected to the side of the U-shaped plate 88. A spring 810 is fixedly connected to the bottom of the rack 86, and the end of the spring 810 away from the rack 86 is fixedly connected to the inner wall of the body 1. A water mist nozzle 811 is fixedly connected to the side of the water tank 81.

[0033] In some examples, the following are also included: the number of support feet 2 is set to be several and symmetrical to each other along the vertical central axis of the body 1, which can evenly distribute the overall weight of the equipment to the ground and avoid tilting or vibration caused by the shift of the center of gravity; the number of springs 810 is set to be two and symmetrical to each other along the vertical central axis of the rack 86; the meshing section of the half gear 84 and the rack 86 pushes the rack 86 to slide upward, which can ensure that the rack 86 is evenly stressed during the movement, prevent the rack 86 from tilting or misaligning with the half gear 84 due to excessive tension on one side, avoid jamming, and ensure the stability and reliability of the transmission mechanism.

[0034] The hinge shafts 3 are arranged in a linear array on the inner wall of the machine body 1. This can distribute the weight of the sealing door 4 and the torque during opening and closing to multiple connection points, preventing a single hinge shaft 3 from being deformed or broken due to excessive load, and improving the reliability of the connection between the sealing door 4 and the machine body 1. Several heat dissipation vents are provided on the side of the machine body 1 and are arranged in a linear array on the side of the machine body 1. The evenly distributed heat dissipation vents can prevent temperature dead zones inside the machine body 1, ensure the uniformity of the temperature field inside the vulcanizing chamber, and prevent rubber products from being over-vulcanized or under-vulcanized due to local overheating. Several water mist nozzles 811 are arranged in a linear array on the side of the water tank 81, which can make the water mist cover the internal space of the vulcanizing chamber in a planar manner, avoiding local over-wetting or spray blind spots caused by traditional single-point spraying.

[0035] The side of the water tank 81 is provided with a sliding groove. There are several sliding grooves arranged in a linear array on the side of the water tank 81. The side of the connecting plate 87 is fixedly connected with a sliding strip. The width of the sliding strip is equal to the width of the sliding groove, which provides rigid guidance in the linear direction and ensures that it moves in a straight line along a fixed path under the drive of the motor 83, avoiding deviation or jamming due to uneven force.

[0036] One end of the spring 810 is located on the displacement trajectory of the rack 86, ensuring that the rack 86 can be forcibly reset along the preset path by the tension of the spring 810 after the half gear 84 disengages, avoiding incomplete reset due to inertia or friction, and ensuring the periodic accuracy of the reciprocating motion. The width of the rack 86 is equal to the width of the half gear 84, ensuring that the tooth surfaces of the two are in complete contact when meshing, avoiding local load concentration or meshing misalignment caused by width difference, maximizing the transmission of driving force, and reducing slippage or wear. The half gear 84 has spokes on its side, and the number of spokes is set to several, and they are arranged in a circumferential array on the side of the half gear 84, distributing the stress of the half gear 84 body and the shaft hole connection area to multiple spokes, avoiding gear deformation or breakage due to unilateral meshing force.

[0037] For example, such as Figures 1-5 As shown, the motor 83 drives the half gear 84 to rotate. When the half gear 84 meshes with the rack 86, it pushes the rack 86 to slide upward, while stretching the spring 810 and driving the connecting plate 87, U-shaped plate 88 and water supply plate 89 to move horizontally. After the half gear 84 disengages, the spring 810 releases its elastic potential energy, causing the rack 86 to fall back, forming a reciprocating linear motion. The sliding groove on the side of the water tank 81 cooperates with the sliding strip of the connecting plate 87 to ensure accurate motion trajectory. When the linear array of water mist nozzles 811 moves with the water supply plate 89, it sprays the water in the water tank 81 in the form of atomization.

[0038] like Figures 1-5 As shown, it illustrates a multi-layer rubber vulcanizing machine according to another embodiment of the present disclosure, which is largely the same as the above-described technical solution. Therefore, only the differences are described in detail. It includes: a vulcanizing compression mechanism 9, which includes a sliding shaft 91. One end of the sliding shaft 91 is fixedly connected to the inner wall of the machine body 1. A hollow block 92 is slidably connected to the circumferential surface of the sliding shaft 91. A template 93 is fixedly connected to the circumferential surface of the hollow block 92. An extrusion block 94 is fixedly connected to the bottom of the template 93. A return spring 95 is fixedly connected to the bottom of the hollow block 92. A fixing plate 96 is fixedly connected to the other end of the sliding shaft 91. A hydraulic tank 97 is fixedly connected to the inner wall of the fixing plate 96. A hydraulic rod 98 is slidably connected to the bottom of the hydraulic tank 97. One end of the hydraulic rod 98 is fixedly connected to a hydraulic plate 99. An L-shaped plate 910 is fixedly connected to the side of the U-shaped plate 88. A hydraulic plate 911 is fixedly connected to the side of the L-shaped plate 910.

[0039] In some examples, the following are also included: a number of sliding shafts 91 are arranged in a circular array on the inner wall of the machine body 1 to form a three-dimensional symmetrical support structure, which evenly distributes the pressure generated by the hydraulic system during vulcanization to the inner wall of the machine body 1 in all directions, avoiding deformation or cracking of the machine body 1 caused by single-point force; a number of hollow blocks 92 are arranged in a linear array on the circumferential surface of the sliding shafts 91, so that the vulcanizing machine can process multiple layers of rubber raw materials at the same time, greatly improving production efficiency.

[0040] The number of return springs 95 is set to several and arranged in a linear array on the circumference of the slide shaft 91 to ensure uniform force distribution along the axial direction, avoid overload of a single return spring 95, and improve the reliability of the mechanism. One end of the return spring 95 is located on the displacement trajectory of the hollow block 92. The return spring 95 can limit the maximum displacement of the hollow block 92, provide buffering at the end of the movement, and reduce impact noise and mechanical wear.

[0041] The template 93 and the extrusion block 94 are set in a number and are arranged in a linear array on the circumference of the slide shaft 91. The parallel distribution of multiple components can realize multi-station synchronous operation and improve efficiency. The size of the mold hole on the side of the template 93 is larger than the size of the extrusion block 94. The size difference is used to form an extrusion gap. Pressure is applied to the material through relative motion to realize the molding operation.

[0042] The top of the extrusion block 94 is located on the displacement trajectory of the hydraulic plate 99, ensuring that the hydraulic pressure is converted into mechanical pressure without deviation, pushing the extrusion block 94 into the die hole of the template 93. The dimensions of the hydraulic plate 99 and the hydraulic plate 911 are equal to the inner wall size of the hydraulic tank 97, ensuring that there is no lateral leakage of hydraulic pressure when it is pressurized, and the pressure loss is close to zero.

[0043] For example, such as Figures 1-5 As shown, the hydraulic rod 98 inside the hydraulic tank 97 drives the hydraulic plate 99 to move downwards. Because the top of the extrusion block 94 is located on the displacement trajectory of the hydraulic plate 99, the hydraulic plate 99 pushes the extrusion block 94 into the die hole of the template 93, applying pressure to the rubber raw material. The circular array of sliding shafts 91 provides guidance and support for the hollow block 92, the template 93, and the extrusion block 94. The linear array of hollow blocks 92 can slide along the sliding shafts 91. With the help of the return spring 95, the rubber is reset after the hydraulic pressure is removed. The second hydraulic plate 911 is connected to the water mist spraying mechanism 8 through the L-shaped plate 910, which can coordinate the control of different processes. The components cooperate with each other to complete the extrusion, vulcanization, and reset process of the rubber, realizing the simultaneous processing of multiple layers of rubber.

[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.
