Description

Technical Field

[0001] This utility model relates to the field of rubber production technology, and in particular to a flat vulcanizing machine for rubber production. Background Technology

[0002] The mold of a flat vulcanizing machine is a tool used to shape rubber products. It is placed between the upper and lower heating plates of the vulcanizing machine. Under heating and pressure, the rubber raw material undergoes a vulcanization reaction, thereby obtaining rubber products with a certain shape, elasticity and strength.

[0003] Rubber vulcanization is a process in which rubber molecules form a three-dimensional network structure through a cross-linking agent under heating and pressure. During this process, if the rubber formulation contains volatile substances, low-boiling-point additives, vulcanization byproducts, or incompletely reacted organic matter, these substances may volatilize or decompose at high temperatures, thus forming visible fumes or odorous gases, as illustrated by the prior art in Chinese patent publication number "CN214353645U". A flat vulcanizing machine for rubber production is provided, comprising a machine body with a lower heating plate and an upper heating plate at its upper and lower ends for heating the rubber, respectively. An insulation seat is placed inside the machine body on top of the lower heating plate. A heating frame is fixedly engaged inside the insulation seat, extending through the insulation seat to its upper and lower ends. The upper and lower ends of the heating frame are on the same plane as the upper and lower ends of the insulation seat. The insulation seat can house the heating frame in a through groove, and the external temperature is isolated by an insulating cavity and a heat insulation plate surrounding the through groove. This prevents the temperature of the heating frame and the template from decreasing due to external temperature, allowing the temperature of the heating frame and the template to remain at a constant level, reducing heat loss and achieving energy saving. The machine has a simple structure and strong practicality.

[0004] Currently, during the vulcanization production of rubber, different types of rubber produce different fumes during vulcanization. Some rubbers produce smoke particles or odors during vulcanization, which can easily pollute the entire production workshop if not treated locally. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a rubber production flat vulcanizing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Design a rubber production flat vulcanizing machine, including an operating table, an insulation platform fixedly installed at the upper center of the operating table, a heating plate mounted on the upper end of the insulation platform, and columns fixedly distributed along the four corners of the upper end of the operating table, with a common support platform installed along the upper ends of the four columns. Cylinders are symmetrically distributed and fixed at the lower end of the support platform. The cylinders are equipped with piston rods for extension and retraction. The ends of the two piston rods distributed on both sides are jointly installed with the same connecting plate. Both the connecting plate and the heat insulation platform are made of ceramic material. A second heating plate is assembled at the lower end of the connecting plate. The upper end of the operating table is also symmetrically distributed with fixed limit posts. Both sides of the heating plate one are fixedly installed with limit sleeve one by brackets. Both sides of the heating plate two are fixedly installed with limit sleeve two by brackets. Limit sleeve one and limit sleeve two are slidably sleeved with the limit posts.

[0007] Preferably, a plurality of heating tubes are embedded and fixed inside the heating plate, and the ends of the plurality of heating tubes are all mounted on the same power socket.

[0008] Preferably, a plurality of heating tubes are embedded and fixed inside the heating plate, and the ends of the plurality of heating tubes are all mounted on the same power socket.

[0009] Preferably, a dust collection hood is fixedly installed on one side of the support platform by a bracket, and the dust collection hood has an inner cavity, with a grid embedded and fixed at the port of the inner cavity.

[0010] Preferably, an air extractor is fixedly installed on the upper end of the support platform by a bracket. The air extractor is of the vortex type, and the air inlet flange of the air extractor is connected to an air suction pipe. The other end of the air suction pipe is embedded in the upper end of the dust collection hood, and the air suction pipe is also connected to the inner cavity.

[0011] Preferably, the air outlet of the air pump is provided with a filter cartridge, and a filter element is embedded and fixed inside the filter cartridge. The filter element is a non-woven fabric core cylinder structure.

[0012] Preferably, both ends of the filter cartridge are covered and fixed with transition interfaces. The transition interfaces located on one side are connected to the air outlet flange of the air pump, and the transition interfaces located on the other side are connected to the flange with a connection port.

[0013] The design scheme proposed in this utility model has the following beneficial effects in application: 1. This utility model has a limiting column structure on the operating table, and matching limiting sleeves are installed on both sides of the upper heating plate and the lower heating plate. This design enables the upper heating plate to maintain a stable vertical trajectory when it moves up and down under the drive of the cylinder, effectively avoiding horizontal deviation or shaking. Through this precise guiding mechanism, not only is the parallelism between the upper and lower heating plates ensured, but also the rubber material can be uniformly pressurized and heated during the vulcanization process. 2. This utility model embeds multiple independent electric heating tubes inside the lower heating plate and the upper heating plate, and connects them to the external control system through a unified power socket. This allows the operator to accurately set and adjust the vulcanization temperature according to the process requirements of different rubber materials. The simultaneous operation of the upper and lower heating plates can heat the rubber material on both sides, which greatly shortens the heat conduction time and ensures uniform heat penetration from the surface to the core. 3. This utility model is specially equipped with a flue gas treatment system consisting of a dust collection hood, an exhaust fan, and a filter cartridge on the support platform. The smoke and dust and harmful gases generated during the vulcanization process are first collected by the dust collection hood and initially filtered through the built-in grid to remove large particulate impurities. Then, the exhaust fan transports the gas to the filter cartridge device through a pipeline. The non-woven fabric filter element in the filter cartridge can effectively trap fine particulate pollutants. The gas that has undergone preliminary purification is then transported to external professional purification equipment for further treatment through a connecting pipeline.
