Description

Technical Field

[0001] This utility model belongs to the technical field of rubber compound production equipment, and more specifically, it relates to a cooling device for rubber compound production. Background Technology

[0002] During the production of rubber compounds, the temperature of the rubber compound is usually high after being mixed in equipment such as internal mixers, generally around 100-150℃. If the high-temperature rubber compound is not effectively cooled in time, it will not only affect the processing quality and efficiency of subsequent processing steps (such as calendering and extrusion), but may also lead to problems such as scorching and performance degradation, seriously affecting the quality of the final product.

[0003] Based on the above, current methods for cooling rubber compounds require continuous conveying via rollers and cooling equipment. However, after cooling, tiny impurities easily adhere to the surface. Traditional cooling devices typically use rollers with a fixed spacing, resulting in rigid contact with the rubber compound. When rubber compounds containing impurities pass through, these impurities are easily squeezed between the roller and the rubber compound. This not only scratches and wears the roller, shortening its service life, but also causes scratches or indentations on the rubber surface due to rigid extrusion, damaging surface smoothness, compromising product appearance, and negatively impacting subsequent processing and finished product quality. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model relates to a cooling device for rubber compound production. It solves the problem that traditional cooling devices often have conveyor rollers with fixed spacing. By incorporating a buffer component, when the upper and lower rollers encounter minute impurities on the surface of the rubber compound, the device adaptively adjusts via a movable belt plate squeezing a spring. This prevents rigid contact between the rollers and impurities, reduces roller wear, extends service life, and prevents impurities from scratching the rubber compound surface due to rigid compression, ensuring the smoothness of the rubber compound's appearance and reducing subsequent processing defects.

[0005] This utility model discloses a cooling device for producing rubber compound, which is achieved through the following specific technical means:

[0013] Furthermore, a rotating support plate is provided at the other end of the top of the supporting frame, and a conveying roller is provided between the rotating support plates. At the same time, a guide roller is provided inside the water tank.

[0014] Furthermore, a limiting component is provided on one side of the conveying roller. The limiting component includes a fixed support frame, a connecting top plate, a bidirectional screw, and a handwheel. A fixed support frame is provided on one side of the conveying roller. The top two ends of the fixed support frame are fixedly connected to the connecting top plate. A bidirectional screw is rotatably installed between the connecting top plates. One end of the bidirectional screw is fixedly connected to the handwheel.

[0015] Furthermore, a movable belt plate is provided between the connecting top plates, and a second screw hole is provided on the movable belt plate.

[0018] This utility model provides a cooling device for rubber compound production, which has the following advantages:

[0019] 1. By setting up a buffer component, when the upper and lower rollers encounter small impurities on the surface of the compound rubber, the rollers will self-adjust by squeezing the spring through the movable belt plate. This avoids rigid contact between the rollers and impurities, reduces roller wear, extends service life, and the elastic adjustment can prevent impurities from scratching the surface of the compound rubber due to rigid squeezing, ensuring the smoothness of the compound rubber appearance and reducing the defect rate in subsequent processing.

[0020] 2. By setting the limit component, it can be flexibly adjusted according to the size of the compound, so as to limit the compound of different sizes and ensure that there is no deviation during conveying.

[0021] 3. By setting up a cooling component, the coolant is delivered to the circulating coil in the water tank by a circulating pump. This can quickly absorb the heat generated by the heat exchange in the water tank, effectively control the water temperature in the tank, and prevent the cooling efficiency of the compound from decreasing due to excessively high water temperature.

[0046] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0047] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0048] This utility model provides a cooling device for rubber compound production, including: a support frame 1 and a buffer assembly 2;

[0049] Support legs 101 are fixedly connected to the four sides of the bottom of the support frame 1. A water tank 102 is provided in the middle of the support frame 1. A buffer assembly 2 is provided at one end of the top of the support frame 1. The buffer assembly 2 includes the following components:

[0050] Fixed vertical plate 201: Fixedly connected to both sides of the top end of the bearing support frame 1. A lower roller 2011 is provided between the fixed vertical plates 201. An extension protrusion 2012 is fixedly connected to the outside of the fixed vertical plate 201. A guide rod 2013 is fixedly connected to both ends between the extension protrusions 2012.

[0051] Fixed support cylinder 202: Located between guide rods 2013, the fixed support cylinder 202 has a cross through groove 2021, and a threaded rod 2022 is rotatably installed inside the fixed support cylinder 202. One end of the threaded rod 2022 passes through the extension protrusion 2012 and is fixedly connected to the top rotating handle 2023.

[0052] Moving ring 203: It is located inside the fixed support cylinder 202. The moving ring 203 has a first screw hole 2031 in the middle. An extension pressure plate 2032 is fixedly connected to the outside of the moving ring 203. The extension pressure plate 2032 extends through the cross groove 2021 to the outside of the fixed support cylinder 202.

[0053] Movable belt plate 204: It is located between the fixed vertical plates 201. Guide holes 2041 are provided at both ends of the movable belt plate 204. A fixed bracket 2042 is fixedly connected to the bottom of the movable belt plate 204. An upper roller 2043 is rotatably installed between the fixed brackets 2042.

[0054] Spring 205: Located on the outside of the fixed support cylinder 202 and at the bottom of the extension pressure plate 2032.

[0055] By rotating the handle 2023, the threaded rod 2022 is driven to rotate. The threaded rod 2022 rotates and engages with the first threaded hole 2031 on the moving ring 203. The moving ring 203 is limited and guided in the cross groove 2021 by the extension pressure plate 2032, so that the threaded rod 2022 drives the moving ring 203 to move. This causes the extension pressure plate 2032 to squeeze the spring 205, changing the preload of the spring 205. When the rubber compound is conveyed, the elasticity provided by the spring 205 can also make the rubber compound stick tightly between the upper roller 2043 and the lower roller 2011. When there are small impurities on the rubber compound, the small impurities will be transmitted to the movable belt plate 204 through the upper roller 2043. The movable belt plate 204 squeezes the spring 205, enabling it to achieve adaptive adjustment, thereby avoiding rigid contact and effectively preventing damage to the roller body or scratches to the rubber compound caused by rigid contact.

[0056] Example 2: Based on Example 1, wherein, as Figures 4 to 6 As shown, a rotating support plate 103 is provided at the other end of the top of the support frame 1, and a conveying roller 1031 is provided between the rotating support plates 103. Meanwhile, a guide roller 104 is provided inside the water tank 102.

[0057] A limiting component 3 is provided on one side of the conveying roller 1031. The limiting component 3 includes a fixed support frame 301, a connecting top plate 3011, a bidirectional lead screw 3012, and a handwheel 3013. A fixed support frame 301 is provided on one side of the conveying roller 1031. The connecting top plate 3011 is fixedly connected to both ends of the top of the fixed support frame 301. A bidirectional lead screw 3012 is rotatably installed between the connecting top plates 3011. One end of the bidirectional lead screw 3012 is fixedly connected to the handwheel 3013.

[0058] A movable belt plate 302 is provided between the top plate 3011 and the movable belt plate 302. A second screw hole 3021 is provided on the movable belt plate 302. A connecting protrusion 3022 is fixedly connected to the bottom of the movable belt plate 302. The connecting protrusion 3022 passes through the limiting slide groove 3023 and is fixedly connected to the rotating bracket 3024 at the bottom. A limiting roller 3025 is installed on the rotating bracket 3024.

[0059] A cooling assembly 4 is provided on one side of the water tank 102. The cooling assembly 4 includes a coolant tank 401, a circulation pump 4011, a delivery pipe 4012, and a circulation coil 4013. The coolant tank 401 is provided on one side of the water tank 102. The circulation pump 4011 is provided on the top of the coolant tank 401. One end of the circulation pump 4011 is connected to the coolant tank 401, and the other end is fixedly connected to the circulation coil 4013 in the water tank 102 through the delivery pipe 4012.

[0060] The other end of the circulating coil 4013 is connected to the cooler 402 through the return pipe 4014, and the other end of the cooler 402 is fixedly connected to the coolant tank 401.

[0061] By rotating the handwheel 3013, the bidirectional lead screw 3012 is driven to rotate. The bidirectional lead screw 3012 engages with the second screw hole 3021 on the moving belt plate 302. Since the moving belt plate 302 is limited and guided in the limiting groove 3023 by the connecting protrusion 3022, the bidirectional lead screw 3012 drives the two sets of moving belt plates 302 to move in opposite directions, thereby changing the spacing between the limiting rollers 3025. This allows for limiting according to the width of the compound rubber, preventing deviation during conveying. The water in the water tank 102 is used to adjust the flow of the compound rubber. The compound rubber is cooled, but the water in the water tank 102 will rise in temperature due to heat exchange over a long period of time. At this time, the circulating pump 4011 is started to draw coolant from the coolant tank 401 and transport it in the circulating coil 4013 to cool the water in the water tank 102. After circulation, the coolant enters the cooler 402 through the return pipe 4014, and is cooled down by the cooler 402. After the coolant is cooled down, it is transported back to the coolant tank 401, thus cooling the water in the water tank 102.

[0062] The specific usage and function of this embodiment are as follows:

[0063] In this invention, rotating the handwheel 3013 drives the bidirectional lead screw 3012 to rotate. The bidirectional lead screw 3012 engages with the second screw hole 3021 on the movable belt plate 302. Since the movable belt plate 302 is limited and guided within the limiting groove 3023 by the connecting protrusion 3022, the bidirectional lead screw 3012 drives the two sets of movable belt plates 302 to move in opposite directions, thereby changing the spacing between the limiting rollers 3025. This allows for limiting according to the width of the compound rubber, preventing deviation during conveying. Then, through... The conveyor roller 1031 conveys the rubber compound through the guide roller 104 into the water tank 102 for water cooling. The cooled rubber compound then enters between the upper roller 2043 and the lower roller 2011. When there are small impurities on the rubber compound, these impurities are transferred to the movable belt plate 204 through the upper roller 2043. The movable belt plate 204 then compresses the spring 205, enabling it to self-adjust and avoid rigid contact. This effectively prevents damage to the roller body or scratches to the rubber compound caused by rigid contact.
