Description

Technical Field

[0001] This utility model relates to the field of rubber roller processing technology, and in particular to a vulcanization equipment for rubber roller production. Background Technology

[0002] Rubber roller vulcanization is a key process in its production. This process promotes the cross-linking reaction of rubber through heating, thereby improving the strength, hardness, elasticity and other properties of the rubber, while achieving a firm bond between the rubber and the roller core. Large rubber rollers are generally vulcanized in vulcanizing tanks, with steam as the main heating method, but hot air and hot water can also be used. During vulcanization, a slow heating and pressurization method must be adopted. Large rubber rollers stay in the tank for 24-48 hours.

[0003] Regarding the aforementioned technologies, the inventors discovered that when existing vulcanizing tanks are used to vulcanize rubber rollers, the rubber rollers are typically placed statically inside the vulcanizing tank. However, when the rubber rollers are heated and vulcanized at high temperatures inside the vulcanizing tank, trace amounts of gas in the rubber layer are difficult to expel, easily leading to air bubble defects inside the rubber layer. Furthermore, the rubber compound softens due to heat during vulcanization and is prone to sagging under gravity, resulting in significant differences in the thickness of the rubber layer and thus reducing the quality of the rubber rollers. In addition, when the support shafts at both ends of the rubber rollers are short, the support shafts rest on the support frame without any extra length extending out. After the vulcanization work is completed and the rollers are removed from the vulcanizing tank, the outer surface of the rubber rollers is relatively soft after heating, making it impossible to directly use the crane's hoisting ropes for lifting. It is necessary to wait for the rubber rollers to cool down before unloading, thereby reducing the efficiency of the vulcanization work. Utility Model Content

[0004] The main technical problem solved by this utility model is to provide a vulcanization equipment for rubber roller production, which improves product quality and vulcanization efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a vulcanizing equipment for producing rubber rollers is provided, comprising: a heating cylinder with one end open and a circular sealing plate disposed at its opening end, wherein a plurality of bottom support seats are connected at intervals on the outer circumference of the heating cylinder, and two first guide rails are symmetrically connected to the inner wall of the heating cylinder, and a movable frame is rolledly connected on the two first guide rails, and one end of the movable frame is fixedly connected to the circular sealing plate. One end of the movable frame is connected to a U-shaped frame, and the other end is connected to a sliding frame assembly. Two drive-type bearing wheel assemblies are symmetrically connected to the upper surface of the U-shaped frame, and two driven-type bearing wheel assemblies corresponding to the drive-type bearing wheel assemblies are symmetrically connected to the upper surface of the sliding frame assembly. The drive-type bearing wheel assembly is connected to a Y-shaped support frame, which is suitable for supporting the rubber roller that has detached from the drive-type bearing wheel assembly. The driven-type bearing wheel assembly is connected to the Y-shaped support frame, which is suitable for supporting the rubber roller that has detached from the driven-type bearing wheel assembly. It also includes a rotary drive mechanism that drives the drive-type bearing wheel assembly to rotate and a linear drive mechanism that drives the circular sealing plate to move along the axis of the heating cylinder.

[0006] By adopting the above technical solution, during use, one end of the rubber roller to be vulcanized is placed on the drive-type bearing wheel assembly and rolled together with it, while the other end is placed on the driven-type bearing wheel assembly and rolled together with it. Then, the linear drive mechanism is operated to move the moving frame into the heating cylinder. After the circular sealing plate is in complete contact with the opening of the heating cylinder, the moving frame stops moving. Next, the rotary drive mechanism is operated to drive the drive-type bearing wheel assembly to rotate, which in turn drives the rubber roller to rotate slowly. This allows the heat inside the heating cylinder to be evenly distributed to the rubber roller, effectively enhancing the vulcanization effect. At the same time, the continuous slow rotation of the rubber roller reduces the probability of large differences in the rubber layer thickness even under the action of gravity, significantly improving the quality of the rubber roller. Because the sliding frame assembly can slide along the length of the moving frame, the gap between the driving load-bearing wheel assembly and the corresponding driven load-bearing wheel assembly can be adjusted, facilitating the vulcanization of rubber rollers of different lengths and greatly improving versatility. When the support shafts at both ends of the rubber roller are short and have no excess length extending outside the driving and driven load-bearing wheel assemblies, after the vulcanization work is completed, the driving and driven load-bearing wheel assemblies are operated to make the rubber roller roll into the inner cavity of the Y-shaped support frame, where the two Y-shaped support frames support the rubber roller. At this time, part of the support shafts at both ends of the rubber roller are located outside the Y-shaped support frames, making it easy to connect the lifting ropes on the gantry crane to the support shafts at both ends of the rubber roller for unloading. Subsequently, the subsequent rubber rollers can be vulcanized, effectively improving vulcanization efficiency.

[0007] In a preferred embodiment, the present invention can be further configured such that: the movable frame includes a movable frame body and two first H-shaped rollers, the first H-shaped rollers are spaced apart and connected to the lower surface of one end of the movable frame body, and the first H-shaped rollers are respectively rolledly connected to the corresponding first guide rails.

[0008] By adopting the above technical solution, since the first H-shaped rollers are respectively connected to the corresponding first guide rails in a rolling manner, it is easy to use a small force to drive the moving frame body to move along the axis of the heating cylinder. The structure is simple and the operation is convenient.

[0009] In a preferred embodiment, the present invention can be further configured as follows: the sliding frame assembly includes a horizontal plate and two second guide rails spaced apart and connected to the movable frame; the four corners of the lower surface of the horizontal plate are respectively connected to support legs; the lower ends of the support legs are respectively connected to second H-shaped rollers; the second H-shaped rollers are respectively connected to the corresponding second guide rails in a rolling connection; the bottoms of the two support legs along the front-rear direction are respectively connected to connecting plates; and wing bolts are spirally threaded through the connecting plates.

[0010] By adopting the above technical solution, the second H-shaped rollers at the lower end of the outriggers are respectively connected to the corresponding second guide rails in a rolling manner. Only a small force is needed to drive the horizontal plate to move along the length of the moving frame, thereby driving the driven bearing wheel assembly to adjust its position, adapting to the vulcanization requirements of rubber rollers of different lengths, and effectively enhancing its versatility. Once the position of the driven bearing wheel assembly is determined, rotating the wing bolts to make its end fit tightly against the side of the second guide rail can achieve the positioning of the driven bearing wheel assembly in the axial direction of the heating cylinder.

[0011] In a preferred embodiment, the present invention can be further configured as follows: the drive-type bearing wheel assembly includes a first U-shaped fixed seat and a first U-shaped movable seat, a drive support wheel is rotatably connected inside the first U-shaped fixed seat, and an auxiliary support wheel is rotatably connected inside the first U-shaped movable seat; it also includes a first spiral drive component for driving the first U-shaped movable seat to move; The first spiral drive component includes a first screw spirally threaded through a first U-shaped movable seat. One end of the first screw passes through and is rotatably connected to a first U-shaped fixed seat, and the other end is rotatably connected to a first mounting seat. Both the first U-shaped fixed seat and the first mounting seat are connected to the upper surface of the U-shaped frame. The first U-shaped movable seat is in contact with the upper surface of the U-shaped frame. Two first guide rods are spaced apart on one side of the first U-shaped fixed seat. One end of each first guide rod passes through and is slidably connected to the first U-shaped movable seat. A first horizontal block is connected to one side of the first U-shaped fixing seat, and the Y-shaped support frame is connected to the first horizontal block. The first screw has a first round hole at one end near the first U-shaped fixing seat, and a detachable rod-shaped handle is inserted into the first round hole.

[0012] By adopting the above technical solution, the support shaft at the end of the rubber roller is located between the drive support wheel and the auxiliary support wheel, and the support shaft is rolledly connected to both the drive support wheel and the auxiliary support wheel. Under the driving action of the rotary drive mechanism, the drive support wheel rotates, which in turn drives the rubber roller to rotate, so that the rubber layer on the rubber roller is heated evenly, enhancing the vulcanization effect. After the vulcanization work is completed, the rubber roller moves to the outside of the heating cylinder. The operator uses a rod-shaped handle inserted into the first circular hole to operate the rod-shaped handle to drive the first screw to rotate. The first screw drives the first U-shaped moving seat away from the first U-shaped fixed seat. The auxiliary support wheel in the first U-shaped moving seat separates from the support shaft at the end of the rubber roller, and the rubber roller rolls into the inner cavity of the Y-shaped support frame. A portion of the support shaft at the end of the rubber roller extends to the outside of the Y-shaped support frame, facilitating the connection between the crane's hoisting rope and the support shafts at both ends of the rubber roller for unloading. Subsequently, the subsequent rubber rollers can continue to be vulcanized, effectively improving the vulcanization efficiency.

[0013] In a preferred embodiment, the present invention can be further configured as follows: the driven bearing wheel assembly includes a second U-shaped fixed seat and a second U-shaped movable seat, wherein a driven support wheel is rotatably connected to the second U-shaped fixed seat and the second U-shaped movable seat respectively, and further includes a second spiral drive member for driving the second U-shaped movable seat to move; The second spiral drive component includes a second screw spirally threaded through the second U-shaped movable seat. One end of the second screw passes through and is rotatably connected to the second U-shaped fixed seat, and the other end is rotatably connected to a second mounting seat. Both the second U-shaped fixed seat and the second mounting seat are connected to the upper surface of the sliding frame assembly. The second U-shaped movable seat is in contact with the upper surface of the sliding frame assembly. Two second guide rods are spaced apart on one side of the second U-shaped fixed seat. One end of each second guide rod passes through and is slidably connected to the second U-shaped movable seat. A second horizontal block is connected to one side of the second U-shaped fixing seat, and the Y-shaped support frame is connected to the second horizontal block. A second round hole is provided at one end of the second screw near the second U-shaped fixing seat, and a detachable rod-shaped handle is inserted into the second round hole.

[0014] By adopting the above technical solution, the support shaft at the end of the rubber roller is located between the driven support wheels, and the support shaft at the end of the rubber roller is rolledly connected to the driven support wheels, which facilitates the rotation of the rubber roller under the action of the rotary drive mechanism. When it is necessary to unload the vulcanized rubber roller, the operator inserts the second rod-shaped handle into the second round hole on the second screw, and operates the second rod-shaped handle to drive the second screw to rotate. The second screw drives the driven support wheel in the second U-shaped moving seat to move away from the second U-shaped fixed seat. The rubber roller rolls and moves to the inner cavity of the Y-shaped support frame connected to the second horizontal block. The Y-shaped support frame supports the rubber roller, and part of the support shaft at the end of the rubber roller extends to the outside of the Y-shaped support frame, which facilitates the connection of the crane's hoisting rope to the support shaft at both ends of the rubber roller to achieve unloading. Then, the subsequent rubber rollers can continue to be vulcanized, effectively improving the vulcanization efficiency.

[0015] In a preferred embodiment, the present invention can be further configured as follows: the rotary drive mechanism includes a driven gear, a vertical drive gear, and sprockets respectively fitted and connected to the outer circle of one end of the drive support wheel, the sprockets are connected by a chain, and the driven gear is fitted and connected to the outer circle of one end of one of the drive support wheels; The circular sealing plate has a rectangular hole and also includes a side moving seat. A rotating shaft is horizontally inserted through the side moving seat. One end of the rotating shaft passes through the rectangular hole and is fitted with the vertical drive gear. A first motor that drives the rotating shaft to rotate is installed on the side moving seat. Two slide rails are connected at intervals on the outer end face of the circular sealing plate. The side moving seat is connected between the two slide rails. A rectangular plate is connected to the outer end face of the circular sealing plate. An electric push rod is connected to the rectangular plate. The extended end of the electric push rod is connected to the side of the side moving seat.

[0016] By adopting the above technical solution, after the circular sealing plate and the opening of the heating cylinder are tightly fitted, the electric push rod is operated to drive the side moving seat to move. The side moving seat then drives the vertical driving gear on the rotating shaft to move and mesh with the driven gear. After the first motor starts, it drives the rotating shaft to rotate. The rotating shaft drives the driving support wheel on one of the driving bearing wheel assemblies to rotate through the transmission action of the vertical driving gear and the driven gear. Since both driving support wheels of the two driving bearing wheel assemblies are equipped with sprockets, and the two sprockets are connected by a chain, the two driving support wheels rotate synchronously, thereby driving the corresponding rubber roller to rotate slowly. This not only enhances the uniformity of heating of the rubber roller, but also reduces the probability of large differences in the thickness of the rubber layer under the action of gravity, significantly improving the finished quality of the rubber roller.

[0017] In a preferred embodiment, the present invention can be further configured as follows: the linear drive mechanism includes a base frame, two third guide rails are symmetrically connected to the upper surface of the base frame, a rack fixed on the base frame is provided between the two third guide rails, two vertical fixed seats are connected at intervals on the circular sealing plate, the lower ends of the vertical fixed seats are respectively connected to third H-shaped rollers, the third H-shaped rollers are respectively rolledly connected to the corresponding third guide rails, an L-shaped seat is connected to the end face of the circular sealing plate, a second motor is connected to the L-shaped seat, a horizontal drive gear is mounted on the output shaft of the second motor, the horizontal drive gear meshes with the rack, and a limit baffle is connected to the end of the base frame away from the heating cylinder.

[0018] By adopting the above technical solution, after the second motor starts, it drives the horizontal drive gear to rotate. The horizontal drive gear meshes with the rack and pinion, thereby driving the L-shaped seat to move. The L-shaped seat drives the moving frame to move along the first guide rail through the circular sealing plate. At the same time, the third H-shaped roller at the lower end of the vertical fixed seat fixed on the circular sealing plate rolls with the corresponding guide rail to ensure that the moving frame moves smoothly and stably. By setting the limit baffle, the horizontal drive gear and the rack are prevented from separating, thus achieving the purpose of limiting.

[0019] In summary, this utility model has at least one of the following beneficial technical effects: 1. The rubber roller rotates slowly during vulcanization, resulting in more uniform heating and better vulcanization effect. At the same time, it reduces the difference in rubber layer thickness caused by gravity, thus improving the quality of the finished product.

[0020] 2. The sliding frame assembly can adjust the gap between the driven bearing wheel assembly (60) and the driving bearing wheel assembly (50) to accommodate rubber rollers of different lengths and enhance the versatility of the equipment.

[0021] 3. By using a Y-shaped support frame to assist in unloading, the problem of hoisting short support shaft rubber rollers is solved, thereby improving the overall efficiency of vulcanization operations. Attached Figure Description

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] It should be noted that these figures are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0030] Reference Figures 1-5 This utility model discloses a vulcanizing equipment for producing rubber rollers, comprising: a heating cylinder 1 with one end open and a circular sealing plate 2 disposed at its open end; a plurality of bottom support seats 11 are connected at intervals on the outer circumference of the heating cylinder 1; two first guide rails 12 are symmetrically connected to the inner wall of the heating cylinder 1; a movable frame 30 is rotatably connected to the two first guide rails 12; one end of the movable frame 30 is fixedly connected to the circular sealing plate 2.

[0031] The movable frame 30 includes a movable frame body 31 and two first H-shaped rollers 32. The first H-shaped rollers 32 are spaced apart and connected to the lower surface of one end of the movable frame body 31. The first H-shaped rollers 32 are respectively rolledly connected to the corresponding first guide rails 12. Since the first H-shaped rollers 32 are rolledly connected to the corresponding first guide rails 12, it is easy to use a small force to drive the movable frame body 31 to move along the axial direction of the heating cylinder 1. The structure is simple and the operation is convenient.

[0032] One end of the movable frame 30 is connected to a U-shaped frame 13, and the other end is connected to a sliding frame assembly 40.

[0034] The sliding frame assembly 40 includes a horizontal plate 41 and two second guide rails 42 spaced apart and connected to the movable frame 30. Support legs 43 are connected to the four corners of the lower surface of the horizontal plate 41, and second H-shaped rollers 44 are connected to the lower ends of the support legs 43. The second H-shaped rollers 44 are in rolling connection with their corresponding second guide rails 42. Connecting plates 45 are connected to the bottom of the two support legs 43 along the front-rear direction, and wing bolts 46 are spirally threaded through the connecting plates. The second H-shaped rollers 44 at the lower ends of the support legs 43 are in rolling connection with their corresponding second guide rails 42. Only a small force is needed to drive the horizontal plate 41 to move along the length of the movable frame 30, thereby adjusting the position of the driven bearing wheel assembly 60 to adapt to the vulcanization requirements of rubber rollers of different lengths, effectively enhancing its versatility. Once the position of the driven bearing wheel assembly 60 is determined, rotating the wing bolts 46 to make its end fit tightly against the side of the second guide rail 42 achieves the positioning of the driven bearing wheel assembly 60 along the axial direction of the heating cylinder 1.

[0035] The drive-type load-bearing wheel assembly 50 includes a first U-shaped fixed seat 51 and a first U-shaped movable seat 52. A drive support wheel 53 is rotatably connected inside the first U-shaped fixed seat 51, and an auxiliary support wheel 54 is rotatably connected inside the first U-shaped movable seat 52. It also includes a first spiral drive member 55 that drives the first U-shaped movable seat 52 to move.

[0036] The first spiral drive component 55 includes a first screw 551 spirally threaded on the first U-shaped movable seat 52.

One end of the first guide rod 553 passes through the first U-shaped movable seat 52 and is slidably connected to it.

[0037] A first horizontal block 56 is connected to one side of the first U-shaped fixed seat 51. The Y-shaped support frame 14 is connected to the first horizontal block 56. A first circular hole 57 is provided at one end of the first screw 551 near the first U-shaped fixed seat 51. A detachable rod-shaped handle 58 is inserted into the first circular hole 57. The support shaft at the end of the rubber cylinder is located between the drive support wheel 53 and the auxiliary support wheel 54, and the support shaft is tactilely connected to the drive support wheel 53 and the auxiliary support wheel 54 respectively. Under the driving action of the rotary drive mechanism 70, the drive support wheel 53 is driven to rotate. The drive support wheel 53 drives the rubber roller to rotate, so that the rubber layer on the rubber roller is heated evenly, which enhances the vulcanization effect. After the vulcanization process is completed, the rubber roller is moved to the outside of the heating cylinder 1. The operator uses a rod-shaped handle 58 inserted into the first circular hole 57 to rotate the first screw 551. The first screw 551 drives the first U-shaped moving seat 52 away from the first U-shaped fixed seat 51. The auxiliary support wheel 54 inside the first U-shaped moving seat 52 separates from the support shaft at the end of the rubber roller. The rubber roller rolls into the inner cavity of the Y-shaped support frame 14. A portion of the support shaft at the end of the rubber roller extends to the outside of the Y-shaped support frame 14, facilitating the connection between the crane's hoisting rope and the support shafts at both ends of the rubber roller for unloading. Subsequently, the subsequent rubber rollers can continue to be vulcanized, effectively improving the vulcanization efficiency.

[0038] The driven bearing wheel assembly 60 includes a second U-shaped fixed seat 61 and a second U-shaped movable seat 62, with driven support wheels 63 rotatably connected to the second U-shaped fixed seat 61 and the second U-shaped movable seat 62 respectively, and also includes a second spiral drive member 64 that drives the second U-shaped movable seat 62 to move.

[0039] The second spiral drive component 64 includes a second screw 641 spirally threaded on the second U-shaped movable seat 62. One end of the second screw 641 passes through the second U-shaped fixed seat 61 and is rotatably connected to it, while the other end is rotatably connected to the second mounting seat 642. Both the second U-shaped fixed seat 61 and the second mounting seat 642 are connected to the upper surface of the sliding frame assembly 40. The second U-shaped movable seat 62 is in contact with the upper surface of the sliding frame assembly 40. Two second guide rods 643 are spaced apart on one side of the second U-shaped fixed seat 61. One end of each second guide rod 643 passes through the second U-shaped movable seat 62 and is slidably connected to it.

[0040] A second horizontal block 65 is connected to one side of the second U-shaped fixing seat 61. The Y-shaped support frame 14 is connected to the second horizontal block 65. A second round hole 66 is provided at one end of the second screw 641 near the second U-shaped fixing seat 61. A detachable rod-shaped handle 67 passes through the second round hole 66. The support shaft at the end of the rubber roller is located between the driven support wheels 63, and the support shaft at the end of the rubber roller is rolledly connected to the driven support wheels 63, which facilitates the rotation of the rubber roller under the action of the rotary drive mechanism 70. When it is necessary to unload the vulcanized rubber roller, the operator inserts the rod-shaped handle 67 into the second round hole 66 on the second screw 641. Operating the rod-shaped handle 67 drives the second screw 641 to rotate. The second screw 641 drives the driven support wheel 63 in the second U-shaped moving seat 62 to move away from the second U-shaped fixed seat 61. The rubber roller rolls and moves to the inner cavity of the Y-shaped support frame 14 connected to the second horizontal block 65. The Y-shaped support frame 14 supports the rubber roller. Part of the support shaft at the end of the rubber roller extends to the outside of the Y-shaped support frame 14, which facilitates the connection between the crane's hoisting rope and the support shaft at both ends of the rubber roller to achieve unloading. Then, the subsequent rubber rollers can continue to be vulcanized, effectively improving the vulcanization efficiency.

[0041] It also includes a rotary drive mechanism 70 that drives the drive-type bearing wheel assembly 50 to rotate and a linear drive mechanism 80 that drives the circular sealing plate 2 to move along the axis of the heating cylinder 1.

[0042] The rotary drive mechanism 70 includes a driven gear 71, a vertical drive gear 72, and sprockets 73 respectively fitted onto the outer circumference of one end of the drive support wheel 53. A chain 74 is connected between the sprockets 73. The driven gear 71 is fitted onto the outer circumference of one end of the drive support wheel 53. The circular sealing plate 2 is provided with a rectangular hole 75 and also includes a side moving seat 76. A rotating shaft 77 is horizontally inserted through the side moving seat 76. One end of the rotating shaft 77 passes through the rectangular hole 75 and is fitted onto the vertical drive gear 72. A first motor 78 is installed on the side moving seat 76 to drive the rotating shaft 77 to rotate. Two slide rails 79 are connected at intervals on the outer end face of the circular sealing plate 2. The side moving seat 76 is connected between the two slide rails 79. A rectangular plate 79a is connected to the outer end face of the circular sealing plate 2. An electric push rod 79b is connected to the rectangular plate 79a. The extended end of the electric push rod 79b is connected to the side of the side moving seat 76.

[0043] After the circular sealing plate 2 is tightly fitted with the opening of the heating cylinder 1, the electric push rod 79b is operated to drive the side moving seat 76 to move. The side moving seat 76 then drives the vertical drive gear 72 on the rotating shaft 77 to move and mesh with the driven gear 71. After the first motor 78 is started, it drives the rotating shaft 77 to rotate. The rotating shaft 77 drives the drive support wheel 53 on one of the drive bearing wheel assemblies 50 to rotate through the transmission action of the vertical drive gear 72 and the driven gear 71. Since both drive support wheels 53 of the two drive bearing wheel assemblies 50 are equipped with sprockets 73, and the two sprockets 73 are connected by a chain 74, the two drive support wheels 53 rotate synchronously, thereby driving the corresponding rubber roller to rotate slowly. This not only enhances the uniformity of heating of the rubber roller, but also reduces the probability of large differences in the thickness of the rubber layer under the action of gravity, significantly improving the finished quality of the rubber roller.

[0044] The linear drive mechanism 80 includes a base frame 81. Two third guide rails 82 are symmetrically connected to the upper surface of the base frame 81. A rack 83 fixed on the base frame 81 is provided between the two third guide rails 82. Two vertical fixed seats 84 are connected at intervals on the circular sealing plate 2. The lower ends of the vertical fixed seats 84 are respectively connected to third H-shaped rollers 85. The third H-shaped rollers 85 are respectively in rolling connection with the corresponding third guide rails 82. An L-shaped seat 86 is connected to the end face of the circular sealing plate 2. A second motor 87 is connected to the L-shaped seat 86. A horizontal drive gear 88 is mounted on the output shaft of the second motor 87. The horizontal drive gear 88 is meshed with the rack 83. After the second motor 87 starts, it drives the horizontal drive gear 88 to rotate. The horizontal drive gear 88 meshes with the rack 83, thereby driving the L-shaped seat 86 to move. The L-shaped seat 86 drives the moving frame 30 to move along the first guide rail 12 through the circular sealing plate 2. At the same time, the third H-shaped roller 85 at the lower end of the vertical fixed seat 84 fixed on the circular sealing plate 2 rolls with the corresponding guide rail to ensure that the moving frame 30 moves smoothly and steadily. The setting of the limit baffle 89 prevents the horizontal drive gear 88 from separating from the rack 83, thus achieving the purpose of limiting.

[0045] The implementation principle of this embodiment is as follows: In use, one end of the rubber roller to be vulcanized is placed on the drive-type bearing wheel assembly 50 and rolled to it, and the other end is placed on the driven-type bearing wheel assembly 60 and rolled to it. Then, the linear drive mechanism 80 is operated to drive the moving frame 30 to move into the heating cylinder 1. After the circular sealing plate 2 is in complete contact with the opening of the heating cylinder 1, the moving frame 30 stops moving. Then, the rotary drive mechanism 70 is operated to drive the drive-type bearing wheel assembly 50 to rotate, which in turn drives the rubber roller to rotate slowly, so that the heat in the heating cylinder 1 is evenly applied to the rubber roller, effectively enhancing the vulcanization effect. At the same time, the rubber roller continues to rotate slowly, which can reduce the probability of large differences in the thickness of the rubber layer even under the action of gravity, and significantly improve the quality of the rubber roller. Since the sliding frame assembly 40 can slide along the length of the moving frame 30, the gap between the driving bearing wheel assembly 50 and the corresponding driven bearing wheel assembly 60 can be adjusted, facilitating the vulcanization of rubber rollers of different lengths and greatly improving versatility. When the support shafts at both ends of the rubber roller are short and have no extra length extending outside the driving bearing wheel assembly 50 and the driven bearing wheel assembly 60, after the vulcanization work is completed, the driving bearing wheel assembly 50 and the driven bearing wheel assembly 60 are operated to make the rubber roller roll into the inner cavity of the Y-shaped support frame 14, where the two Y-shaped support frames 14 support the rubber roller. At this time, part of the support shafts at both ends of the rubber roller are located outside the Y-shaped support frame 14, which facilitates the connection between the hoisting rope on the trolley and the support shafts at both ends of the rubber roller to achieve unloading. Subsequently, the subsequent rubber rollers can be vulcanized, effectively improving the vulcanization efficiency.
