Description

Technical Field

[0001] This utility model relates to the field of rubber sheet processing technology, and in particular to a rubber sheet air drying device. Background Technology

[0002] Rubber sheet drying and shaping equipment is used to dry and shape the manufactured rubber sheets. Generally, rubber sheets contain a lot of moisture after production, which needs to be evaporated by air drying to make the rubber reach the required hardness and shape, thereby improving production efficiency and product quality.

[0003] Currently, in existing technologies, such as CN214842303U, there is a rubber hot sheet drying device that uses a PLC controller to adjust the conveying speed of the hot sheet and extends the cooling channel to achieve complete air drying and cooling of the hot sheet. This device is suitable for rubber processing. However, due to the different uses of rubber sheets, some rubber sheets are generally dried with cold air in order to better protect their physical and chemical properties and avoid problems such as aging and cracking caused by excessive hot air drying or direct cold air blowing. Although the drying speed of cold air is relatively slow, it can protect the rubber sheet.

[0004] However, traditional air-drying devices use fans to blow air onto the rubber sheet for cooling. This air-cooling method is uneven, resulting in uneven temperature after the rubber dries. The different thermal shrinkage rates on the outer surface of the rubber sheet cause unevenness on the outer surface. Utility Model Content

[0005] The purpose of this invention is to provide a rubber sheet drying device to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides a rubber sheet drying device, including a frame, a suspension mechanism mounted on the frame, and a drying mechanism; a wire mesh box is hung on the suspension mechanism, and the wire mesh box is used to hold the rubber sheet; the drying mechanism is located above and below the wire mesh box; the drying mechanism includes a cold air box, an air supply component disposed in the cold air box, and multiple air outlet branches communicating with the cold air box, the multiple air outlet branches are spaced apart along the wire mesh box, and each air outlet branch has multiple air outlet holes evenly arranged along its length direction, the air outlet holes facing the rubber sheet.

[0007] Preferably, in the above-mentioned rubber sheet drying device, the suspension mechanism includes a suspension frame, on which long hanging hooks are arranged opposite each other, and on both sides of the net box, hanging points are arranged opposite each other, and the net box is suspended from the long hanging hooks through the hanging points.

[0008] Preferably, in the above-mentioned rubber sheet drying device, the mesh size of the wire mesh box is smaller than the minimum size of the rubber sheet.

[0009] Preferably, in the above-mentioned rubber sheet drying device, the air supply assembly includes a fan and an air supply main pipe disposed at the air outlet of the fan, and the air supply main pipe is connected to the air outlet branch pipe.

[0010] Preferably, in the above-mentioned rubber sheet drying device, a filter assembly is further provided inside the cold air box. The filter assembly is located at the air inlet of the fan and is used to filter the air entering the fan.

[0011] Preferably, in the above-mentioned rubber sheet drying device, the drying mechanism located above the net box and the drying mechanism located below the net box have the same structure and are arranged symmetrically.

[0012] Preferably, in the above-mentioned rubber sheet drying device, the frame is further provided with support legs, and the bottom of the support legs is provided with anti-slip pads.

[0013] Therefore, the rubber sheet drying device of the present invention, which adopts the above-described structure, has the following beneficial effects:

[0014] (1) The air-drying mechanism is set above and below the mesh cage, and the upper and lower structures are symmetrical. Through the air outlet branches distributed at intervals along the mesh cage and the air outlet holes evenly set on the branches, the upper and lower surfaces of the rubber sheet are simultaneously and evenly supplied with air. The cold air is blown onto the rubber sheet from the air outlet holes with a uniform wind speed and air volume, avoiding the local wind force that is too strong or too weak caused by the direct blowing of traditional fans. This makes the evaporation rate of moisture on the surface of the rubber sheet uniform, and the temperature distribution is uniform after air drying. This significantly reduces the problem of uneven surface caused by different thermal shrinkage amplitudes, and improves the appearance quality and physical property stability of the rubber sheet.

[0015] (2) The suspension mechanism uses a long hook to connect with the suspension point of the wire mesh box, so that the wire mesh box is stably suspended on the frame, which facilitates the loading and unloading of the rubber sheet. The mesh size of the wire mesh box is smaller than the minimum size of the rubber sheet, which can effectively prevent the rubber sheet from falling or shifting during the drying process. At the same time, the mesh structure allows cold air to penetrate, ensuring that the rubber sheet is in full contact with the cold air and improving the drying efficiency.

[0016] (3) The filter assembly installed inside the cold air box is located at the air inlet of the fan. It can filter dust, impurities and other pollutants in the air, avoid contaminating the surface of the rubber sheet, and protect its chemical and physical properties. The air outlet branch pipe is connected to the cold air box by a flange, and a sealing gasket is installed on the flange. This not only ensures the airtightness of the air supply system, but also facilitates disassembly and maintenance. The filter assembly can be quickly replaced or the air supply pipeline can be inspected, which improves the convenience of equipment maintenance.

[0017] (4) Anti-slip pads are installed on the support legs at the bottom of the frame to enhance the stability of the device during operation and prevent positional displacement caused by fan vibration. The symmetrical upper and lower drying mechanism design can adapt to rubber sheets of different thicknesses and sizes. By adjusting the fan speed or the layout of the air outlet, the drying rate can be flexibly controlled, thereby improving production efficiency while protecting the performance of the rubber sheet.

Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

The singular forms “a,” “the,” and “the” used in the embodiments of this utility model and the appended claims are also intended to include the plural forms, and “multiple” generally includes at least two unless the context clearly indicates otherwise.

[0024] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that an article or device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such an article or device. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.

[0025] This utility model provides a rubber sheet drying device, including a frame 1, a suspension mechanism 2 disposed on the frame 1, and a drying mechanism 3; a wire mesh box 21 is hung on the suspension mechanism 2, and the wire mesh box 21 is used to hold the rubber sheet; the drying mechanism 3 is disposed above and below the wire mesh box 21; the drying mechanism 3 includes a cold air box 31, an air supply component 32 disposed in the cold air box 31, and a plurality of air outlet branches 33 communicating with the cold air box 31, the plurality of air outlet branches 33 are spaced apart along the wire mesh box 21, and each air outlet branch 33 has a plurality of air outlet holes evenly disposed along its length direction, the air outlet holes being oriented towards the rubber sheet.

[0026] The suspension mechanism 2 includes a suspension frame 22, on which long hanging hooks 23 are arranged opposite each other. The long hanging hooks 23 are hung on the suspension frame 22. The net cage 21 has hanging points arranged opposite each other on both sides, and it is suspended from the long hanging hooks 23 through the hanging points. The mesh size of the net cage 21 is smaller than the minimum size of the rubber sheet.

[0027] The air supply assembly 32 includes a fan 321 and an air supply main duct 322 located at the air outlet of the fan 321. The air supply main duct 322 is connected to the air outlet branch duct 33. A filter assembly 34 is also provided inside the cold air box 31. The filter assembly 34 is located at the air inlet of the fan 321 and is used to filter the air entering the fan 321.

[0028] The drying mechanism 3 located above the net cage 21 and the drying mechanism 3 located below the net cage 21 have the same structure and are arranged symmetrically. The frame 1 is also equipped with support legs, and the bottom of the support legs is equipped with anti-slip pads.

[0029] Working Principle: The rubber sheet to be dried is placed inside the mesh box 21. The mesh box 21 is suspended from the suspension hooks 23 of the suspension mechanism 2 via suspension points on both sides, ensuring that the mesh box is horizontally and stably suspended in the middle of the frame 1. The mesh structure of the mesh box 21 allows cold air to penetrate while preventing the rubber sheet from falling, keeping the rubber sheet in a suspended state so that the upper and lower surfaces can contact the cold air simultaneously. After the fan 321 is started, external air enters through the air inlet of the cold air box 31. It first passes through the filter assembly 34 to remove dust, particles, and other impurities. The purified air is then distributed to the various outlet branches 33 through the main air supply pipe 322. Since the outlet branches 33 are spaced along the length of the mesh box 21, and the air outlet holes on each branch are evenly arranged and facing the rubber sheet, the cold air is blown onto the upper and lower surfaces of the rubber sheet at a uniform flow rate and pressure through the air outlet holes. The upper and lower drying mechanisms 3 work synchronously, forming a symmetrical cold air circulation system. Cool air makes full contact with the rubber sheet surface, carrying away moisture and achieving evaporative drying. Due to the uniform layout of the air outlets and symmetrical airflow, the evaporation rate of moisture on the rubber sheet surface is consistent across all areas, avoiding uneven thermal shrinkage caused by localized overheating or undercooling. This ensures that the dried rubber sheet has a uniform temperature, a smooth surface, and stable physical properties (such as hardness and shape). Anti-slip pads at the bottom of the support legs ensure the stability of the device during fan operation and reduce the impact of vibration. When maintenance is required, the air outlet branch pipe can be quickly disassembled via the flange to replace the filter assembly or clean the air supply channel, ensuring the clean and efficient operation of the air supply system.

[0030] Therefore, this utility model provides a rubber sheet drying device with the above-mentioned structure. The drying mechanism is located above and below the mesh box, and the upper and lower structures are symmetrical. Through the air outlet branches distributed at intervals along the mesh box and the air outlet holes evenly arranged on the branches, synchronous and uniform airflow is achieved to the upper and lower surfaces of the rubber sheet. Cold air is blown onto the rubber sheet from the air outlet holes at a uniform speed and volume, avoiding the localized excessively strong or weak airflow caused by direct blowing from traditional fans. This ensures a consistent rate of moisture evaporation on the rubber sheet surface, resulting in a uniform temperature distribution after drying. This significantly reduces surface unevenness caused by different thermal shrinkage rates, improving the appearance quality and physical property stability of the rubber sheet. The suspension mechanism, through the cooperation of long hanging hooks with the suspension points of the mesh box, stably suspends the mesh box on the frame, facilitating the loading and unloading of the rubber sheet. The mesh size of the mesh box is smaller than the minimum size of the rubber sheet, effectively preventing the rubber sheet from falling or shifting during the drying process. Simultaneously, the mesh structure allows cold air to penetrate, ensuring full contact between the rubber sheet and the cold air, thus improving drying efficiency. The filter assembly inside the cold air box is located at the fan inlet, filtering dust, impurities, and other pollutants from the air to prevent contamination of the rubber sheet surface and protect its chemical and physical properties. The outlet branch pipe is connected to the cold air box via flanges with sealing gaskets, ensuring the airtightness of the air supply system and facilitating disassembly and maintenance. This allows for quick replacement of the filter assembly or inspection of the air supply duct, improving equipment maintenance convenience. Anti-slip pads on the support legs at the bottom of the frame enhance the stability of the device during operation, preventing positional shifts caused by fan vibration. The symmetrical upper and lower drying mechanism design accommodates rubber sheets of different thicknesses and sizes. By adjusting the fan speed or the layout of the air outlets, the drying rate can be flexibly controlled, improving production efficiency while protecting the rubber sheet's performance.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
