Description

Technical Field

[0001] This utility model relates to the field of vulcanization equipment technology, specifically a vacuum flat vulcanizing machine. Background Technology

[0002] Flat vulcanizing machines are mainly used for vulcanizing flat rubber belts (such as conveyor belts and transmission belts, referred to as flat belts). They are hydraulic machines, and their main function is to provide the pressure and temperature required for vulcanization. Pressure is generated by the hydraulic system through hydraulic cylinders, and temperature is provided by the heating medium. Conveyor belt flat vulcanizing machines are mainly used for vulcanizing flat rubber belts, rubber sheets, polymer sheets, and other flat products. They have advantages such as high pressure per unit area of ​​the hot plate, reliable operation, and low maintenance. Temperature is provided by the heating medium (usually steam, heat transfer oil, etc.). Flat belt vulcanizing machines can be mainly divided into two categories according to the frame structure: column-type and frame-type. They can also be divided into single-layer and multi-layer types according to the number of working layers, and into oil-pressure and water-pressure types according to the working medium of the hydraulic system.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the present invention, a vacuum flat vulcanizing machine includes a vulcanizing machine base 1. A lower template 7 is rotatably mounted in the through hole 6 in the middle of the vulcanizing machine base 1 via a connecting shaft 11. An upper template 4 is mounted on the upper side of the vulcanizing machine base 1 via an upper bracket 3 and a first hydraulic cylinder 5. A PLC control cabinet 10 for overall operation is mounted on the outer side of the upper bracket 3. Both the upper template 4 and the lower template 7 have an electric heating layer on one side. A product vulcanizing tank 8 is mounted on the upper side of the lower template 7. The equipment is placed in a vacuum chamber, and then the rubber product to be vulcanized is placed in the product vulcanizing tank 8. The upper template 4 is driven to move down and press onto the rubber product by the first hydraulic cylinder 5, while the electric heating layer heats the rubber product, thereby performing vulcanization treatment. A discharge plate 14 is elastically slidably mounted at the bottom of the product vulcanizing tank 8 via a support rod 15, a spring 17, and an extrusion end plate 16. A sliding through-hole is installed at the bottom of the vulcanizing tank 8, and a spring 17 is sleeved on the outside of the support rod 15 between the lower template 7 and the extrusion end plate 16. One end of the connecting shaft 11 is connected to the motor 13 via a gear set. The gear set includes a driven gear 22 at one end of the connecting shaft 11, and a driving gear 12 that meshes with the driven gear 22 at one end of the motor 13. The motor 13 is a stepper motor and is fixedly installed in the through hole of the vulcanizing machine base 1. The motor 13 and the gear set drive the connecting shaft 11 to rotate and adjust, so that the opening of the vulcanizing tank 8 on one side of the lower template 7 faces downward. Then, the first hydraulic cylinder 5 drives the upper template 4 to move down to extrude the discharge plate 14 and the extrusion end plate 16. The product in the vulcanizing tank 8 is extruded and falls into the receiving hopper 9 for storage under the action of the discharge plate 14, making the unloading convenient and quick.

[0023] like Figure 1 and Figure 2 As shown, in order to improve the functionality of use, a lower support 2 is provided on the lower side of the vulcanizing machine base 1, and a receiving hopper 9 is placed on the upper side of the stable support plate inside the lower support 2, which facilitates the receiving and processing of the vulcanized rubber products in the lower template 7, thereby improving the functionality of use.

[0024] like Figure 1 and Figure 3 As shown, in order to improve the structural stability of the lower template 7 during vulcanization, a locking block 19 is provided in the groove 21 on one side of the vulcanizing machine base 1 through the second hydraulic cylinder 20. A locking groove 18 is provided on one side of the lower template 7 to be laterally inserted into the locking block 19. The locking groove 18 is a rectangular groove and the locking block 19 is a rectangular block. This allows the locking block 19 to be laterally inserted into the locking groove 18 on one side of the lower template 7 by driving the second hydraulic cylinder 20. This enables the lower template 7 to be laterally positioned during vulcanization, which facilitates the structural stability of the lower template 7 during vulcanization.

[0025] The working principle and usage process of this utility model are as follows: When unloading is required, the connecting shaft 11 is rotated and adjusted by the motor 13 and the gear set, so that the opening of the product vulcanizing tank 8 on one side of the lower template 7 is downward. Then, the upper template 4 is driven to move down by the first hydraulic cylinder 5 to squeeze the unloading plate 14 and the extrusion end plate 16. The product in the product vulcanizing tank 8 is squeezed out and falls into the receiving hopper 9 for storage under the action of the unloading plate 14, which makes unloading convenient and quick.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
