Description

Technical Field

[0001] This utility model relates to the field of sound and heat insulation cotton molding technology, specifically to a molding device for sound and heat insulation cotton. Background Technology

[0002] As a key functional material, sound and heat insulation cotton has a wide and important application in many fields such as construction, automobile manufacturing, and home appliances. Its excellent sound and heat insulation performance plays a vital role in improving building comfort, automobile driving experience, and home appliance energy efficiency. However, the current molding device for sound and heat insulation cotton lacks a real-time and precise adjustment mechanism for pressure control during the molding process, making it difficult to ensure that the pressure is applied to the material evenly and stably. This can easily lead to uneven density distribution of the sound and heat insulation cotton, which in turn seriously affects the stability of its sound and heat insulation performance. Therefore, we propose a molding device for sound and heat insulation cotton. Utility Model Content

[0003] The purpose of this invention is to provide a molding device for sound and heat insulation cotton, which has the advantage of precise pressure control. This solves the problem that current molding devices for sound and heat insulation cotton lack a real-time and precise adjustment mechanism for pressure control during the molding process, making it difficult to ensure that the pressure is applied to the material evenly and stably. This can easily cause uneven density distribution of the sound and heat insulation cotton, which in turn seriously affects the stability of its sound and heat insulation performance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a molding device for sound and heat insulation cotton, comprising a base plate, a worktable fixedly connected to the top of the base plate via a bracket, a groove being formed at the middle of the top of the worktable, a damper being fixedly connected to the bottom of the inner cavity of the groove, a spring being sleeved on the outer surface of the damper, a lower mold being fixedly connected to the top of the damper, a top plate being fixedly connected to the top of the worktable via a bracket, an electric telescopic rod being fixedly connected to the bottom of the top plate, a pressure plate being fixedly connected to the bottom of the electric telescopic rod, and a pressure sensor being provided between the pressure plate and the electric telescopic rod.

[0005] Preferably, an air nozzle is fixedly connected to the top left end of the workbench via a bracket, a refrigeration box is fixedly connected to the top left end of the base plate via a bracket, a cooler is fixedly connected to the inner cavity of the refrigeration box, a fan is fixedly connected to the left side of the refrigeration box, the air intake of the fan is fixedly connected to the bottom of the left side of the inner cavity of the refrigeration box via a pipe, the air outlet of the fan is connected to the air nozzle via a pipe, and an air inlet is provided on the right side of the refrigeration box.

[0006] Preferably, the heat dissipation surface of the cooler extends to the lower end of the bottom of the cooling box, and the heat dissipation surface of the cooler is provided with a radiator.

[0007] Preferably, heating grooves are provided in the lower part of the inner cavity of the lower mold and the inner cavity of the pressure plate. An electric heating plate is fixedly connected to the inner cavity of the heating groove, and a temperature sensor is fixedly connected to the right side of the inner cavity of the heating groove.

[0008] Preferably, limiting grooves are provided on both the left and right sides of the inner cavity of the groove, and limiting blocks are fixedly connected to the lower parts of both the left and right sides of the lower mold, and the limiting blocks are movably connected to the inner cavity of the limiting grooves.

[0009] Preferably, a battery box is fixedly connected to the right end of the top of the base plate, and a storage battery is fixedly connected to the inner cavity of the battery box.

[0010] Preferably, a PLC controller and a display are respectively installed on the front of the workbench. The output terminal of the PLC controller is electrically connected to the input terminals of the fan, electric telescopic rod, cooler and heating plate. The input terminals of the PLC controller and the display are electrically connected to the output terminals of the pressure sensor and the temperature sensor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model uses a pressure sensor installed between the pressure plate and the electric telescopic rod to accurately sense the pressure applied by the pressure plate to the sound and heat insulation cotton material in real time. When the pressure value is fed back to the PLC controller, the PLC controller will precisely control the extension and retraction of the electric telescopic rod according to the preset pressure parameters. When the pressure approaches the set upper limit, the PLC controller will promptly instruct the electric telescopic rod to slow down or stop pressing to avoid excessive pressure damaging the material structure. When the pressure is insufficient, the electric telescopic rod will continue to press down until a suitable pressure value is reached. This precise pressure control can effectively avoid quality problems such as uneven density, loose structure, or over-compaction of the sound and heat insulation cotton due to improper pressure. Furthermore, the damper and spring in the groove can effectively buffer the impact of pressure during the pressing process of the pressure plate, preventing the lower mold from being damaged by excessive instantaneous pressure. At the same time, the limiting blocks on both sides of the lower mold cooperate with the limiting grooves on both sides of the groove to ensure that the lower mold maintains an accurate position throughout the molding process. This not only helps to ensure the regular shape of the sound and heat insulation cotton molding, but also makes the pressure more evenly applied to the material, further improving product quality.

[0013] 2. This utility model incorporates an electric heating plate and a temperature sensor in the heating tank within the lower mold and pressure plate, respectively. The temperature sensor continuously monitors the temperature within the heating tank and transmits the data to the PLC controller in real time. The PLC controller intelligently adjusts the heating power of the electric heating plate according to the preset molding temperature range. After the sound insulation and heat insulation cotton is molded, the cooler in the cooling box rapidly cools it. The fan draws cold air from the bottom left side of the cooling box cavity and blows it quickly onto the molded sound insulation and heat insulation cotton through pipes and air nozzles. Compared to traditional natural cooling methods, this forced air cooling rapid cooling system can reduce the temperature of the sound insulation and heat insulation cotton to a suitable range in a short time, greatly shortening the cooling time and reducing the product's dwell time at the molding station, thereby significantly improving the efficiency of the entire production process.

[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] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1:

[0020] Please see Figure 1-3As shown, this utility model provides a molding device for sound and heat insulation cotton, including a base plate 1. A worktable 3 is fixedly connected to the top of the base plate 1 via a bracket. A groove 20 is formed in the middle of the top of the worktable 3. A damper 21 is fixedly connected to the bottom of the inner cavity of the groove 20. A spring 22 is sleeved on the outer surface of the damper 21. A lower mold 8 is fixedly connected to the top of the damper 21. A top plate 6 is fixedly connected to the top of the worktable 3 via a bracket. An electric telescopic rod 11 is fixedly connected to the bottom of the top plate 6. A pressure plate 7 is fixedly connected to the bottom of the mold. A pressure sensor 12 is installed between the pressure plate 7 and the electric telescopic rod 11. Heating grooves 15 are opened in the lower part of the inner cavity of the lower mold 8 and the inner cavity of the pressure plate 7. An electric heating plate 17 is fixedly connected to the inner cavity of the heating groove 15. A temperature sensor 16 is fixedly connected to the right side of the inner cavity of the heating groove 15. Limiting grooves 19 are opened on both the left and right sides of the inner cavity of the groove 20. Limiting blocks 18 are fixedly connected to the lower part of both the left and right sides of the lower mold 8. The limiting blocks 18 are movably connected to the inner cavity of the limiting grooves 19.

[0021] This technical solution uses a pressure sensor 12 installed between the pressure plate 7 and the electric telescopic rod 11 to accurately sense the pressure applied by the pressure plate 7 to the sound and heat insulation cotton material in real time. When the pressure value is fed back to the PLC controller 9, the PLC controller 9 precisely controls the extension and retraction of the electric telescopic rod 11 according to preset pressure parameters. When the pressure approaches the set upper limit, the PLC controller 9 promptly instructs the electric telescopic rod 11 to slow down or stop pressing to avoid excessive pressure damaging the material structure. When the pressure is insufficient, it instructs the electric telescopic rod 11 to continue pressing until a suitable pressure value is reached. This precise pressure... The control effectively avoids quality problems such as uneven density, loose structure, or excessive compaction of the sound and heat insulation cotton due to improper pressure. Furthermore, the damper 21 and spring 22 in the groove 20 can effectively buffer the impact of pressure during the pressing process of the pressure plate 7, preventing the lower mold 8 from being damaged by excessive instantaneous pressure. At the same time, the limiting blocks 18 on both sides of the lower mold 8 cooperate with the limiting grooves 19 on both sides of the groove 20 to ensure that the lower mold 8 maintains an accurate position throughout the molding process. This not only helps to ensure the regular shape of the sound and heat insulation cotton molding, but also makes the pressure more evenly applied to the raw materials, further improving product quality. Example 2:

[0022] Based on Embodiment 1, this utility model is as follows: Figure 1-3As shown, an air nozzle 5 is fixedly connected to the top left end of the workbench 3 via a bracket, and a refrigeration box 23 is fixedly connected to the top left end of the base plate 1 via a bracket. A cooler 14 is fixedly connected to the inner cavity of the refrigeration box 23, and a fan 4 is fixedly connected to the left side of the refrigeration box 23. The air intake of the fan 4 is fixedly connected to the bottom left side of the inner cavity of the refrigeration box 23 via a pipe, and the air outlet of the fan 4 is connected to the air nozzle 5 via a pipe. An air inlet 13 is provided on the right side of the refrigeration box 23, and the heat dissipation surface of the cooler 14 extends to the refrigeration box 23. At the bottom of the base plate 3, a heat sink is provided on the heat dissipation surface of the cooler 14. A battery box 2 is fixedly connected to the top right end of the base plate 1. A storage battery is fixedly connected to the inner cavity of the battery box 2. A PLC controller 9 and a display 10 are respectively installed on the front of the workbench 3. The output terminal of the PLC controller 9 is electrically connected to the input terminal of the fan 4, the electric telescopic rod 11, the cooler 14 and the heating plate 17. The input terminals of the PLC controller 9 and the display 10 are electrically connected to the output terminals of the pressure sensor 12 and the temperature sensor 16.

[0023] This technical solution involves installing an electric heating plate 17 and a temperature sensor 16 in the heating tank 15 within the lower mold 8 and pressure plate 7, respectively. The temperature sensor 16 continuously monitors the temperature within the heating tank 15 and transmits the data to the PLC controller 9 in real time. The PLC controller 9 intelligently adjusts the heating power of the electric heating plate 17 according to the preset molding temperature range. After the sound insulation and heat insulation cotton is formed, the cooler 14 in the cooling box 23 quickly cools it down. The fan 4 draws cold air from the bottom left side of the inner cavity of the cooling box 23 and blows it quickly onto the formed sound insulation and heat insulation cotton through the pipe and the air outlet nozzle 5. Compared with the traditional natural cooling method, this forced air cooling rapid cooling system can reduce the temperature of the sound insulation and heat insulation cotton to a suitable range in a short time, greatly shortening the cooling time and reducing the dwell time of the product at the molding station, thereby significantly improving the efficiency of the entire production process.

[0024] The working principle of this utility model is as follows: A pressure sensor 12 is installed between the pressure plate 7 and the electric telescopic rod 11, which can accurately sense the pressure applied by the pressure plate 7 to the sound insulation and heat insulation cotton material in real time. When the pressure value is fed back to the PLC controller 9, the PLC controller 9 will precisely control the extension and retraction of the electric telescopic rod 11 according to the preset pressure parameters. When the pressure approaches the set upper limit, the PLC controller 9 will promptly instruct the electric telescopic rod 11 to slow down the pressing speed or stop pressing to avoid excessive pressure damaging the material structure. When the pressure is insufficient, the electric telescopic rod 11 will be instructed to continue pressing until a suitable pressure value is reached. This precise pressure control can effectively avoid quality problems such as uneven density, loose structure, or over-compaction of the sound insulation and heat insulation cotton due to improper pressure. In addition, the damper 21 and spring 22 in the groove 20 can effectively buffer the pressure impact during the pressing process of the pressure plate 7, preventing the lower mold 8 from being damaged by excessive instantaneous pressure. At the same time, the limiting blocks 18 on both sides of the lower mold 8 cooperate with the limiting grooves 19 on both sides of the groove 20. To ensure the lower mold 8 remains in the correct position throughout the molding process, this not only helps maintain the regular shape of the sound and heat insulation cotton but also allows the pressure to be applied more evenly to the raw material, further improving product quality. The lower mold 8 and the heating tank 15 within the pressure plate 7 are equipped with an electric heating plate 17 and a temperature sensor 16, respectively. The temperature sensor 16 continuously monitors the temperature within the heating tank 15 and transmits the data to the PLC controller 9 in real time. The PLC controller 9 intelligently adjusts the heating power of the electric heating plate 17 according to the preset molding temperature range. After the sound and heat insulation cotton is molded, the cooler 14 in the cooling box 23 rapidly cools it. The fan 4 draws cold air from the bottom left side of the cooling box 23's inner cavity and blows it quickly onto the molded sound and heat insulation cotton through the pipe and the air nozzle 5. Compared to traditional natural cooling methods, this forced air cooling system can quickly lower the temperature of the sound and heat insulation cotton to a suitable range, greatly shortening the cooling time and reducing the product's dwell time at the molding station, thus significantly improving the efficiency of the entire production process.
