Description

Technical Field

[0001] The invention belongs to the technical field of plate vulcanizing machines, in particular to a plate vulcanizing machine for producing rubber conveyor belts. Background Art

[0002] The rubber conveyor belt is one of the common components for transporting materials. Different materials are molded into rubber conveyor belts according to needs, and then the conveyor belts are input into a plate vulcanizer. The rubber conveyor belts are heated by the heated heat transfer oil in the plate vulcanizer, and then the rubber conveyor belts are pressed by the high pressure generated by the hydraulic equipment of the plate vulcanizer, and then the rubber conveyor belts are cooled, etc., so as to vulcanize the rubber conveyor belts.

[0003] The Chinese invention application with application number "CN201310382843.8" discloses a gantry type flat plate vulcanizer, including a vulcanizer body, the vulcanizer body includes a frame, a hydraulic system and a hot plate system are arranged on the frame, the upper hot plate system and the lower hot plate system both include an insulation plate and a hot plate, the hot plate includes three heating zones and three cooling zones, the three cooling zones are respectively located at the edges of the three heating zones, each cooling zone has an independent cooling function and does not interfere with each other.

[0004] The above application has the function of independent cooling, but the width of the rubber conveyor belt will change after vulcanization due to the pressure of the vulcanizer and thermal expansion and other factors. The traditional vulcanization equipment uses heat transfer oil to heat the conveyor belt blank to vulcanize it. In order to ensure that the width of the rubber conveyor belt after vulcanization reaches the required specifications, the conveyor belt blank before vulcanization will be relatively wide, but this will cause some unnecessary parts to be heated and vulcanized, so the electric heating rod needs to heat more heat transfer oil for vulcanization. In order to heat more heat transfer oil to the required temperature, the electric heating rod is always kept at a high power, thereby increasing energy consumption, which is not energy-saving enough. In addition, during vulcanization, the excess parts on both sides of the conveyor belt blank will also be vulcanized, with a high hardness, which is not convenient for later cutting.

[0041] A second motor 26 is fixedly connected to the side of the mounting frame 21 away from the supporting frame 1, and a conveying roller 27 is fixedly sleeved on the output shaft of the second motor 26;

[0042] The top of the conveying roller 27 is in the same horizontal plane as the top of the cooling cavity support plate 51 and the top of the moving platform 24 . Both ends of the conveying roller 27 penetrate the mounting frame 21 and are movably connected to the mounting frame 21 .

[0043] In this embodiment, the external hot oil circulation device (existing technology, no more details) is connected to the delivery pipe 43, and the heat transfer oil enters the heat transfer oil space of the upper pressure cavity heating plate 42 along the delivery pipe 43 by gravity, and the input end and the output end of the cold water circulation device (existing technology, no more details) are respectively connected to the two delivery pumps 52, and at this time, there is no cooling water in the inner cavity of the cooling cavity support plate 51;

[0044] The motor 1 22 is started to drive the bidirectional threaded rod 23 to rotate, thereby driving the movable platform 24 meshed with the bidirectional threaded rod 23 to move along the axis direction of the bidirectional threaded rod 23 and the guide rod 25, so that the distance between the two movable platforms 24 is the same as the actual required width of the rubber conveyor belt;

[0045] Then, the rubber conveyor belt is passed through the support frame 1 and is located above the cooling cavity support plate 51, in contact with the conveyor roller 27, and the rubber conveyor belt is connected to an external storage device, so as to prepare to reel up the vulcanized rubber conveyor belt;

[0046] When the moving platform 24 moves, the moving rod 31 is driven to move, thereby driving the lifting adjustment rod 32 to move, and then the lifting adjustment rod 32 drives the adjustment plate 33 to move in the inner cavity of the upper pressure cavity heating plate 42, thereby adjusting the width of the heat transfer oil space, so that the excess heat transfer oil is squeezed out from the retractable delivery pipe 43, and the temperature of the heat transfer oil is detected by the temperature control device 44, and the electric heating rod 45 is started to heat the heat transfer oil to make the heat transfer oil reach the required temperature, and then the hydraulic cylinder 41 is started to drive the upper pressure cavity heating plate 42 to descend, so that The bottom end of the upper pressure cavity heating plate 42 cooperates with the cooling cavity support plate 51 to press the rubber conveyor belt, and the heat transfer oil in the inner cavity of the upper pressure cavity heating plate 42 is used to heat the rubber conveyor belt, thereby controlling the width of the heat transfer oil space and the heating range through the required width of the rubber conveyor belt, so that the heat transfer oil only vulcanizes the required vulcanized part, so that the electric heating rod 45 does not need to heat a lot of heat transfer oil every time, thereby reducing the energy consumption of the electric heating rod 45, saving energy and protecting the environment, and being applicable to vulcanizing rubber conveyor belts of different widths;

[0047] After the vulcanization is completed, the delivery pump 52 is started to deliver cooling water to the inner cavity of the cooling cavity support plate 51 to cool the rubber conveyor belt, and then the cooling water is pumped out from the inner cavity of the cooling cavity support plate 51 by another delivery pump 52 .

[0048] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, the embodiment of the present invention provides a flat vulcanizing machine for producing rubber conveyor belts, wherein the cutting mechanism 6 comprises a transmission belt 61, which is movably sleeved on both ends of the conveying roller 27, and a rotating disk 62 is movably sleeved in the inner cavity of the transmission belt 61, and the rotating disk 62 is movably connected to the mounting frame 21, and the conveying roller 27 is transmission-connected to the rotating disk 62 through the transmission belt 61, and a driven rod 63 is fixedly connected to the side of the rotating disk 62 close to the supporting frame 1, and a lifting plate 64 is slidably connected to the surface of the driven rod 63, and an L-shaped cutting knife 65 is fixedly connected to the bottom of the lifting plate 64, and a guide groove 641 is provided on the top of the lifting plate 64, and the guide groove 641 consists of an inclined groove and straight grooves at both ends, and the driven rod 63 is slidably connected to the inner cavity of the guide groove 641;

[0049] The lifting plate 64 can move along the axis direction of the driven rod 63, and the L-shaped cutting knife 65 is located above the moving platform 24;

[0050] A lifting ring 67 is fixedly connected to the side of the L-shaped cutting knife 65 away from the support frame 1 , and a support rod 66 is fixedly connected to the top of the movable platform 24 . The lifting ring 67 is movably sleeved on the surface of the support rod 66 .

[0051] In this embodiment, the second motor 26 is started to drive the conveying roller 27 to rotate, and the rubber conveying belt is pulled out from the inner cavity of the support frame 1 and is located above the moving platform 24. During the rotation of the conveying roller 27, the transmission belt 61 is driven to operate, and the rotating disk 62 is driven to rotate by the transmission belt 61, and the driven rod 63 is driven to rotate by the rotating disk 62. At this time, the driven rod 63 is slidably connected to the inner cavity of the guide groove 641, driving the lifting plate 64 to operate, and the L-shaped cutting knife 65 is guided by the support rod 66, thereby driving the L-shaped cutting knife 65 to move up and down to cut the rubber conveying belt;

[0052] It should be noted that the width of the heat transfer oil space is controlled by the required width of the rubber conveyor belt, and the heating range is controlled so that the heat transfer oil only vulcanizes the required vulcanized part, so that the excess parts on both sides of the conveyor belt blank are not heated and vulcanized, and therefore have a lower hardness, making the L-shaped cutting knife 65 easier to cut and more convenient to process again after recycling.

[0053] Working principle and use process: Before use, connect the delivery pipe 43 to the external hot oil circulation equipment, connect the input end and output end of the cold water circulation equipment to the two delivery pumps 52 respectively, start the motor 1 22 to drive the two-way threaded rod 23 to rotate, thereby driving the movable platform 24 engaged therewith to move along the axis direction of the two-way threaded rod 23 and the guide rod 25, thereby adjusting the distance between the two movable platforms 24, so that the distance between the two movable platforms 24 is the same as the required width of the conveyor belt;

[0054] When the moving platform 24 moves, the support rod 66 is driven to move, thereby driving the L-shaped cutting knife 65 to move;

[0055] When the moving platform 24 moves, the moving rod 31 is driven to move, thereby driving the lifting adjustment rod 32 to move, and the lifting adjustment rod 32 drives the adjustment plate 33 to move in the inner cavity of the upper pressure cavity heating plate 42, so that the distance between the two adjustment plates 33 is also the same as the required width of the conveyor belt, and the heat transfer oil space in the inner cavity of the upper pressure cavity heating plate 42 is adjusted, so that the excess heat transfer oil is squeezed back to the external heat transfer oil storage device;

[0056] Then, the rubber conveyor belt is passed into the interior of the support frame 1 from the side of the support frame 1 away from the conveyor roller 27, and the other side is in contact with the conveyor roller 27. Then, the electric heating rod 45 is started to heat the heat transfer oil in the inner cavity of the upper pressure cavity heating plate 42, and the temperature is detected by the temperature control device 44, so that the heat transfer oil is heated to the required temperature. Then, the hydraulic cylinder 41 is started again to drive the upper pressure cavity heating plate 42 to move toward the cooling cavity support plate 51, press the rubber conveyor belt, and heat the rubber conveyor belt through the heat transfer oil, thereby completing the vulcanization.

[0057] Then, the hydraulic cylinder 41 is started to drive the upper pressure cavity heating plate 42 to rise, and then the delivery pump 52 is started to input cooling water into the inner cavity of the cooling cavity support plate 51. The rubber conveyor belt is cooled by the cooling water in the inner cavity of the cooling cavity support plate 51, and then the cooling water is returned to the cold water circulation device by another delivery pump 52;

[0058] Then, the motor 26 is started to drive the conveying roller 27 to rotate, thereby conveying the rubber conveyor belt out of the inner cavity of the support frame 1. During the rotation of the conveying roller 27, the transmission belt 61 is driven to operate, and the operation of the transmission belt 61 drives the rotating disk 62 to rotate, and then the rotating disk 62 drives the driven rod 63 to rotate. At this time, the driven rod 63 is slidably connected to the inner cavity of the guide groove 641, driving the lifting plate 64 to operate, and the L-shaped cutting knife 65 is guided by the support rod 66, thereby driving the L-shaped cutting knife 65 to move up and down, cutting the rubber conveyor belt, and removing the excess parts on both sides of the rubber conveyor belt.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
