Description

Technical Field

[0001] This invention relates to the field of rubber vulcanization technology, and in particular to a vulcanization device for a drum vulcanizing machine. Background Technology

[0002] In existing technology, sidewall strips are installed at both ends of the vulcanizing drum of a drum vulcanizing machine. These sidewall strips are made of iron, and need to be replaced when producing conveyor belts of different thicknesses and widths. Replacing the sidewall strips requires using a cutting machine to cut them off, removing and replacing them with suitable models. After tightening, the replaced sidewall strips need to be connected by electric welding, followed by further adjustments. This process is complex, and the cutting machine can easily damage the surface of the vulcanizing drum. Furthermore, welding slag can easily fall into the vulcanizing drum, affecting normal processing. Summary of the Invention

[0003] To address the shortcomings of the aforementioned technologies, this invention provides a vulcanizing device for a drum vulcanizing machine, which makes it easier to replace the sidewall mold strips and provides high stability during use.

[0004] This invention discloses a vulcanizing device for a drum vulcanizing machine, comprising a frame, a main vulcanizing drum, and a secondary vulcanizing drum. The main vulcanizing drum and the secondary vulcanizing drum are both fitted onto the frame, and the secondary vulcanizing drum is located on the side of the main vulcanizing drum. The secondary vulcanizing drum includes at least a first secondary vulcanizing drum and a second secondary vulcanizing drum. Side retaining strips are wound around both ends of the main vulcanizing drum. A tensioning mechanism is provided on the frame between the first and second secondary vulcanizing drums. The side retaining strips are annular and wound around the main vulcanizing drum and the tensioning mechanism. The tensioning mechanism is used to tension the side retaining strips. The two ends of the side retaining strips are connected by pins.

[0005] In the above scheme, during the actual vulcanization process, the conveyor belt enters between the first vulcanizing auxiliary drum and the vulcanizing main drum, wraps around the vulcanizing main drum, and finally exits between the vulcanizing main drum and the second vulcanizing auxiliary drum. The tensioning mechanism is set on the frame between the first and second vulcanizing auxiliary drums. When the side guard strip is wrapped around the tensioning mechanism and the vulcanizing main drum, it is not covered on the vulcanizing main drum between the first and second vulcanizing auxiliary drums, and the conveyor belt does not contact the vulcanizing main drum in this area. Therefore, no side guard is needed in this area. Thus, after the side guard strip is tensioned by the tensioning mechanism, it can still maintain side guarding on the conveyor belt on the vulcanizing main drum, without affecting the vulcanization effect of the conveyor belt. At the same time, the two ends of the side guard strip are plug-in type, which is more convenient during replacement. Only the pin needs to be removed to remove the side guard strip, and after assembly, only plugging is required, followed by tensioning by the tensioning mechanism. The replacement of the side guard strip will not damage the vulcanizing main drum.

[0006] The edge retaining strip includes a long strip-shaped frame and a rubber layer disposed on the outside of the frame, with pins connecting both ends of the long strip-shaped frame. The frame has a certain degree of flexibility, allowing it to rotate around the vulcanizing main drum and tensioning mechanism. The rubber layer covers the edge retaining strip, ensuring a regular and flat surface shape. During rotation, as the edge retaining strip moves to the vulcanizing main drum and tensioning mechanism, the degree of bending varies, and the rubber layer can deform differently to adapt to its normal operation.

[0007] The elongated frame consists of one or more rows of roller chains, with the joints of each row of roller chains aligned with each other. The elongated frame uses multiple rows of roller chains and has an externally vulcanized rubber layer, which makes the bending process of the edge guard strip smoother and effectively reduces its manufacturing cost. The joints are connected via the shafts of the roller chains, making operation simple, convenient, safe, and reliable.

[0008] The tensioning mechanism is a tension roller, with both ends of the tension roller slidably connected to the frame. A thrust mechanism is mounted on the frame, acting on both ends of the tension roller and driving it to move away from the vulcanizing drum. The thrust mechanism can be a pneumatic cylinder, a hydraulic cylinder, or a conventional method such as using a lead screw for tightening; the specific method is not limited.

[0009] The vulcanizing device of the drum vulcanizing machine obtained by the present invention makes it easier to replace the side strips without damaging the vulcanizing drum. Attached Figure Description

[0012] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0013] Example 1:

[0014] like Figure 1As shown, this invention discloses a vulcanizing device for a drum vulcanizing machine, including a frame 1, a main vulcanizing drum 2, and a secondary vulcanizing drum. The main vulcanizing drum 2 and the secondary vulcanizing drum are both fitted onto the frame 1, and the secondary vulcanizing drum is located on the side of the main vulcanizing drum 2. The secondary vulcanizing drum includes at least a first secondary vulcanizing drum 3 and a second secondary vulcanizing drum 4. Side retaining strips 5 are wound around both ends of the main vulcanizing drum 2. A tensioning mechanism 6 is provided on the frame 1 between the first secondary vulcanizing drum 3 and the second secondary vulcanizing drum 4. The side retaining strips 5 are annular and are wound around the main vulcanizing drum 2 and the tensioning mechanism 6. The tensioning mechanism 6 is used to tension the side retaining strips 5. The two ends of the side retaining strips 5 are connected by pins.

[0015] The vulcanizing main drum 2 and vulcanizing auxiliary drum can be configured similarly to existing vulcanizing machines. In the actual vulcanization process, the conveyor belt 7 enters between the first vulcanizing auxiliary drum 3 and the vulcanizing main drum 2, wraps around the vulcanizing main drum 2, and finally exits between the vulcanizing main drum 2 and the second vulcanizing auxiliary drum 4. The tensioning mechanism 6 is positioned on the frame 1 between the first vulcanizing auxiliary drum 3 and the second vulcanizing auxiliary drum 4. When the side guard strip 5 is wrapped around the tensioning mechanism 6 and the vulcanizing main drum 2, it is not covered on the vulcanizing main drum 2 between the first vulcanizing auxiliary drum 3 and the second vulcanizing auxiliary drum 4. Since the conveyor belt 7 does not contact the vulcanizing main drum 2 in this area, no side guard is needed. Therefore, after the tensioning mechanism 6 tensions the side guard strip 5, it can still maintain the side guard on the conveyor belt 7 on the vulcanizing main drum 2, without affecting the vulcanization effect of the conveyor belt 7. Meanwhile, the two ends of the side retaining strip 5 are connected by a plug, which makes it more convenient to replace. The side retaining strip 5 can be removed by simply removing the pin. After assembly, it only needs to be plugged in and then tightened by the tensioning mechanism 6. The replacement of the side retaining strip 5 will not damage the vulcanizing drum 2.

[0016] The edge retaining strip 5 includes a long strip-shaped frame and a rubber layer 52 disposed on the outside of the frame, with pins connecting the two ends of the long strip-shaped frame. The frame has a certain degree of flexibility and can rotate around the vulcanizing main drum 2 and the tensioning mechanism 6. Through the covering of the rubber layer 52, the surface shape of the edge retaining strip 5 can be made regular and flat. During the rotation, when the edge retaining strip 5 runs to the vulcanizing main drum 2 and the tensioning mechanism 6, the degree of bending is different, and the rubber layer 52 can produce different deformations to adapt to its normal operation.

[0017] like Figure 2As shown, the elongated frame consists of multiple rows of roller chains 51, with the joints of each row of roller chains 51 aligned with each other. The elongated frame uses multiple rows of roller chains 51, with an externally vulcanized rubber layer 52, which makes the bending process of the edge retaining strip 5 smoother and effectively reduces its manufacturing cost. The joints are connected via the shafts of the roller chains 51, making operation simple, convenient, and safe. When the multiple rows of roller chains 51 are covered with the rubber layer 52, the connecting parts at both ends are designed with a concave-convex shape, and after they cooperate, a pin can be inserted to form a complete curved edge retaining strip 5. Although there will inevitably be some gaps at the joints in actual operation, it does not affect normal use. A long pin can be used to connect all the roller chains 51 at the joint.

[0018] The tensioning mechanism 6 is a tension roller, and its two ends are slidably connected to the frame 1. A thrust mechanism is provided on the frame 1, which acts on both ends of the tension roller and drives the tension roller to move away from the vulcanizing drum 2. The thrust mechanism can be a pneumatic cylinder or a hydraulic cylinder, or a conventional means such as using a lead screw for tightening, and is not specifically limited.
