Description

Technical Field

[0001] This utility model relates to the field of rubber vulcanization technology, specifically to a rubber secondary vulcanization device. Background Technology

[0002] Secondary vulcanization of rubber, also known as post-vulcanization or two-stage vulcanization, refers to the process of continuing to vulcanize rubber products after they have reached a certain degree of vulcanization. Specifically, when rubber products have vulcanized to a certain extent, even without heating, they can continue to deepen the vulcanization process under the action of residual heat, or during product storage, or under dynamic action to produce continued cross-linking phenomena. This also includes the process of continuing to heat for secondary vulcanization.

[0003] Currently, the common method for secondary vulcanization of rubber products involves introducing hot air into an oven and subjecting the rubber products, placed on racks within the oven, to secondary vulcanization. Since existing racks simply have several shelves, secondary vulcanization is achieved by placing rubber products on each shelf. However, to improve the efficiency of secondary vulcanization, multiple rubber products are often subjected to simultaneous treatment. When multiple rubber products on the same shelf come into contact with each other, they experience mutual compression and adhesion during secondary vulcanization, which affects the vulcanization effect and may even impact the performance of the rubber products, increasing the scrap rate.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on the existing vulcanization equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a rubber secondary vulcanization device to solve the problem mentioned in the background art where multiple rubber products located on the same shelf come into contact with each other and are squeezed and stuck together during secondary vulcanization, thus affecting the secondary vulcanization effect of the rubber products.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber secondary vulcanization device, including a vulcanization oven, a track fixed on the inner wall of the vulcanization oven, a vulcanization frame provided inside the vulcanization oven, a mating protrusion provided on the surface of the vulcanization frame, a baffle provided on the inner side of the vulcanization frame, an installation groove provided on the surface of the baffle, a support net installed inside the vulcanization frame, and a first partition and a second partition respectively provided inside the vulcanization frame, a first slot and a second slot respectively provided on the first partition and the second partition, and an insert strip installed at the lower end of both the first partition and the second partition.

[0007] Preferably, the track side is considered to be a U-shaped structure, and the mating protrusion is slidably connected to the track.

[0008] Preferably, the baffle has a cross-shaped structure and is fixedly connected to the vulcanizing frame.

[0009] Preferably, the baffles divide the vulcanizing frame into a grid structure, and each grid has a supporting mesh welded in it.

[0010] Preferably, the first partition and the second partition are engaged and connected by a first slot and a second slot.

[0011] Preferably, the insert is located in the mounting groove, and both the first partition and the second partition are mounted on the stop bar via the insert and the mounting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the vulcanizing frame is pulled out and installed inside the vulcanizing oven. When multiple rubber products need to be vulcanized simultaneously, only one first partition or second partition needs to be installed onto the baffle through the insert and mounting groove. At this time, the internal space of a single vulcanizing frame is divided into two, which is convenient for placing different rubber products for simultaneous vulcanization. When more rubber products need to be vulcanized simultaneously, the first partition and the second partition are engaged through the first slot and the second slot to form a cross-shaped partition. Then, the partition is installed onto the baffle through the insert and mounting groove. At this time, the internal space of the vulcanizing frame is divided into a grid-shaped structure, which can accommodate more rubber products for simultaneous vulcanization.

[0018] 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.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a rubber secondary vulcanization device, including a vulcanization oven 1, a track 2 fixed on the inner wall of the vulcanization oven 1, a vulcanization frame 3 provided inside the vulcanization oven 1, a mating protrusion 4 provided on the surface of the vulcanization frame 3, the track 2 is viewed from the side as a "U" shaped structure, the mating protrusion 4 is slidably connected to the track 2, so that the vulcanization frame 3 can be pulled and pulled in the vulcanization oven 1 through the mating protrusion 4 and the track 2;

[0020] A baffle 5 is provided on the inner side of the vulcanizing frame 3. The baffle 5 has a cross-shaped structure and is fixedly connected to the vulcanizing frame 3, which improves the stability of the baffle 5 installation and facilitates the subsequent division of the space inside the vulcanizing frame 3. An installation groove 6 is opened on the surface of the baffle 5. A support net 7 is installed inside the vulcanizing frame 3. The baffle 5 divides the vulcanizing frame 3 into a grid structure. A support net 7 is welded in each grid, which facilitates the stacking of rubber inside the vulcanizing frame 3, thereby facilitating its vulcanization.

[0021] The vulcanizing frame 3 is also provided with a first partition 8 and a second partition 9. The first partition 8 and the second partition 9 are respectively provided with a first slot 10 and a second slot 11. The first partition 8 and the second partition 9 are connected by the first slot 10 and the second slot 11, which facilitates the assembly and use of the first partition 8 and the second partition 9. The lower end of the first partition 8 and the second partition 9 are each equipped with a strip 12. The strip 12 is located in the mounting groove 6. The first partition 8 and the second partition 9 are both installed on the baffle 5 through the strip 12 and the mounting groove 6, which is conducive to the installation or removal of the first partition 8 and the second partition 9 on the baffle 5 through the strip 12 and the mounting groove 6.

[0022] Working principle: According to Figures 1-4As shown, when multiple rubber products need to be vulcanized simultaneously, the vulcanizing frame 3 is first pulled out of the vulcanizing oven 1 through the connecting strip 4 and the track 2. Then, a single first partition 8 or second partition 9 is installed onto the baffle 5 through the insert strip 12 and the mounting groove 6. At this time, the internal space of a single vulcanizing frame 3 is divided into two independent spaces, which is convenient for placing different rubber products for simultaneous vulcanization. When more rubber products need to be vulcanized at the same time, the first slot 10 on the first partition 8 and the second slot 11 on the second partition 9 are engaged together. At this time, the first partition 8 and the second partition 9 form a cross-shaped partition. Then, the partition is installed onto the baffle 5 through the insert strip 12 and the mounting groove 6. At this time, the internal space of the vulcanizing frame 3 is divided into a grid-shaped structure, which can accommodate more rubber products for simultaneous vulcanization and also prevent different rubber products from sticking together.
