Description

Technical Field

[0001] This utility model relates to the field of vulcanization equipment technology, specifically to a capsule-type V-belt jaw vulcanizing machine. Background Technology

[0002] The pressure during vulcanization in existing V-belt jaw vulcanizing machines is achieved by a hydraulic system through upper and lower hot plates. This cannot compensate for individual volume differences caused by product weight variations, making defects such as edge defects and material shortages highly likely. The defect rate is around 3%.

[0003] Existing solutions include, for example, Chinese Patent (Application No. 201120372692.4) which discloses a gantry-type V-belt flatbed automatic vulcanizing machine, comprising a main frame, a heating device, a template device, a demolding device, and a cooling and length-fixing device disposed within the main frame area; telescopic devices and belt transfer devices disposed on both sides of the main frame, an electrical control system, and a hydraulic system; and a closed-loop feedback automatic control system; wherein the main frame is a gantry-type frame. Due to the presence of the closed-loop feedback automatic control system, the degree of automation is improved, and production efficiency is higher; because the main frame is a gantry-type frame, it overcomes the defects of traditional jaw-type frames where large clamping forces cause unilateral stress and frame deformation, allowing for increased length and width of the V-belt molds, resulting in longer V-belts; and allowing for multi-layer stacking of V-belt molds, increasing the number of V-belts that can be vulcanized in one pass.

[0004] While it can alleviate problems such as flash and material shortage to some extent, it has high requirements for the material filling process and the equipment itself has a relatively complex structure that requires the linkage of multiple parts. In actual production, there are still shortcomings that need to be improved. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a capsule-type V-belt jaw vulcanizing machine that utilizes heat transfer capsules instead of conventional long transfer plates. This compensates for localized pressure variations caused by varying material quantities, ensuring consistent pressure per unit area even with material deviations. This eliminates defects such as flash and material shortages, thereby improving product yield.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a capsule-type V-belt jaw vulcanizing machine, comprising a frame, a vulcanizing mold disposed on the frame, a drive source disposed within the frame, the vulcanizing mold comprising an upper template, a belt template, and a lower template arranged sequentially from top to bottom, the upper template and the lower template each comprising a mounting base, and a heat transfer bag disposed on the working surface of the mounting base.

[0007] As a further improvement to the above technical solution:

[0008] The mounting base is provided with a storage chamber for placing a heat transfer bag, and the lower surface of the heat transfer bag is flush with the lower end face of the storage chamber.

[0009] The heat transfer bag includes a connecting part and a working part. The working part is made of flexible thermally conductive material, and the connecting part is provided with a positioning module that connects to the storage chamber.

[0010] The positioning module includes a base plate located on the upper part of the heat transfer bag, an extension rod extending to the upper part of the mounting base is provided on the base plate, and a limiting seat is provided on the extension rod.

[0011] The substrate has extension plates at both ends, a gap is reserved between the substrate and the mounting base, and the working part has snap-fit ​​parts located in the gap at both ends.

[0012] The heat transfer bag is provided with an air inlet and an air outlet, and a one-way valve is provided at both the air inlet and the air outlet.

[0013] The beneficial effects of this utility model embodiment are as follows: The capsule-type V-belt jaw vulcanizing machine includes a frame, on which a vulcanizing mold is provided, and a drive source is provided inside the frame. The vulcanizing mold includes an upper template, a belt template, and a lower template distributed from top to bottom. Both the upper template and the lower template include a mounting base. The working surface of the mounting base is provided with a heat transfer bag. The heat transfer bag replaces the conventional long transfer plate, which compensates for the local pressure changes caused by the amount of material in a certain area. This ensures that the pressure per unit area is consistent even when there is a deviation in the material, eliminates defects such as flash and material shortage, and improves the product yield.

[0014] The substrate has extension plates at both ends, and the substrate and the two extension plates are distributed in a U-shape. A gap is reserved between the substrate and the mounting base. The working part has snap-fit ​​parts at both ends that extend into the gap. The working part is fixed by clamping the snap-fit ​​parts with the inner sidewall of the substrate and the mounting base. The structure is simple and can quickly fix the heat transfer bag, which is convenient for operation. Attached Figure Description

[0019] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] like Figure 1 As shown, the capsule-type V-belt jaw vulcanizing machine of this embodiment includes a frame 1, on which a vulcanizing mold is provided. A drive source 2 is located inside the frame 1. The drive source 2 is a hydraulic cylinder that provides power for the operation of the vulcanizing mold. The vulcanizing mold includes an upper template 3, a belt template 4, and a lower template 5 arranged sequentially from top to bottom. Under the drive of the drive source 2, the upper template 3 and lower template 5 approach the belt template 4 to provide heat for the vulcanizing operation. Both the upper template 3 and lower template 5 include a mounting base 6. The working surface of the mounting base 6 is provided with a heat transfer bag 7. The heat transfer bag 7 includes a connecting part 9 and a working part 10. The working part 10 is made of a flexible heat-conducting material, such as... The polymer composite material, graphene, etc., are connected to the positioning module of the storage chamber 8 on the connecting part 9. The heat transfer bag 7 is provided with an air inlet 16 and an exhaust port 17. One-way valves 18 are installed at both the air inlet 16 and the exhaust port 17. Hot steam is used as the heat source. During the vulcanization process, the shape of the surface of the heat transfer bag 7 is changed by pressure according to the flatness of the material surface (i.e., the material is shaped). This ensures that the heat transfer bag 7 is in contact with the material surface, which makes up for the local pressure change caused by the amount of material in a certain area. This ensures that the pressure per unit area is consistent even when there is a deviation in the material, and basically eliminates defects such as flash and material shortage.

[0021] The mounting base 6 has a storage chamber 8 for placing the heat transfer bag 7. The lower surface of the heat transfer bag 7 is flush with the lower end face of the storage chamber 8 to ensure that the heat transfer bag 7 can fit against the material surface to complete the pressure and heat transfer. One side of the mounting base 6 with the storage chamber 8 is the working surface for installing the heat transfer bag 7, and the other side is connected to the drive source 2 for moving closer to or away from the template 4.

[0022] The positioning module includes a base plate 11 located on the upper part of the heat transfer bag 7. An extension rod 12 extending to the upper part of the mounting base 6 is provided on the base plate 11. A limiting seat is provided on the extension rod 12. The extension rod 12 is a screw, and there are multiple screws evenly distributed along the length direction of the mounting base 6. A threaded hole is provided in the middle of the limiting seat to connect with the screw. The limiting seat is located above the mounting base 6, and a rubber pad is placed at the contact point with the mounting base 6 for sealing and heat insulation.

[0023] The substrate 11 has extension plates 13 at both ends, and the substrate 11 and the two extension plates 13 are distributed in a U-shape. A gap 14 is reserved between the substrate 11 and the mounting base 6. The working part 10 has snap-fit ​​parts 15 extending into the gap 14 at both ends. The working part 10 is fixed by clamping the snap-fit ​​parts 15 between the substrate 11 and the inner sidewall of the mounting base 6.

[0024] During use, the drive source 2 drives the upper mold 3 and lower mold 5 to adhere to the material on the mold 4. Then, high-temperature hot steam is delivered into the heat transfer bag 7 through the air inlet 16. The high-temperature hot steam applies pressure to the material while transferring heat. The heat transfer bag 7 can deform during operation to ensure that the working surface is always in contact with the material surface. This compensates for local pressure changes caused by the amount of material in some areas. Even if there are deviations in the material, the pressure per unit area is consistent, which basically eliminates defects such as flash and material shortage. The defect rate is reduced from 3% to about 0.2%, which greatly improves the production yield and reduces production costs.
