Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubber production, in particular to a rubber cooling system. BACKGROUND

[0002] Rubber is a high-elastic polymer material with reversible deformation, and rubber products are widely used in industry and life. Rubber products need to be treated at high temperature during production, and then rapidly cooled, so in industrial production, various rubber cooling devices are usually used.

[0003] In the prior art, a cooling device for rubber product production is disclosed in Chinese Utility Model Patent No. CN215242298U. When the device is used, the rubber can be completely immersed in cold water for cooling by controlling the V-shaped conveying of the conveying belt, thereby improving the cooling effect.

[0004] However, in the above-mentioned cooling device, the contact area between the rubber immersed in the cooling pool and the cooling liquid is small during the cooling and transmission of the rubber, resulting in a small heat exchange amount of the rubber through the cooling pool and poor cooling effect, so subsequent continuous air cooling is still needed to reduce the rubber to a suitable temperature. Moreover, after the rubber is immersed in the cooling liquid, the pressure of the rubber on the conveying belt is reduced due to the buoyancy, thereby reducing the friction between the conveying belt and the rubber, and when the position of the rubber in the cooling liquid changes, the rubber is also subjected to the resistance of the cooling liquid, thereby affecting the stable transmission of the rubber on the conveying belt. In addition, when batches of rubber enter the cooling liquid through the conveying belt, the temperature of the cooling liquid gradually increases with the accumulation of heat in the cooling pool, making it difficult to transfer to the outside, thereby gradually reducing the temperature difference between the cooling liquid and the rubber, resulting in a decrease in the cooling effect of the cooling liquid over time. In addition, the two ends of the conveying belt are located outside the cooling pool, and the conveying belt will inevitably contaminate part of the cooling liquid during rotation. With the rotation of the conveying belt, the cooling liquid moves outside the cooling pool and falls to the ground, polluting the surrounding production environment. Moreover, there is a certain height difference between the two ends of the conveying belt and the ground, and when the device is used, batches of rubber need to be placed on the conveying surface of the conveying belt at a higher position, increasing the workload of workers.

Detailed Implementation

[0057] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0063] A driving mechanism 600 drives the conveying belt 300 to rotate to convey the rubber 1400 through the gap between the conveying surface 301 and the pressing belt 500.

[0064] When the device is used, the rubber 1400 to be cooled is placed at the feeding end of the conveying surface 301, and the driving mechanism 600 is started to drive the conveying belt 300 to rotate and convey the rubber 1400 on the conveying surface 301, during which the rubber 1400 enters the cooling pool 200 filled with cooling liquid to absorb the heat of the rubber 1400 and reduce the temperature of the rubber 1400 after passing through the cooling pool 200. Unlike the prior art, the pressing assembly is further provided in the present application, in which the guide roller 400 guides the pressing belt 500 to gap-match with the conveying surface 301, and the rubber 1400 enters the gap between the conveying surface 301 and the pressing belt 500 when the conveying surface 301 moves to be deformed under the pressure of the pressing belt 500, which on one hand increases the surface area and the contact area with the cooling liquid to improve the heat exchange and the heat exchange effect of the rubber 1400, and on the other hand increases the pressure of the rubber 1400 on the conveying belt 300 to ensure the stable transmission of the rubber 1400 on the conveying belt 300. The pressing belt 500 is in a closed loop and arranged outside each guide roller 400, and during the rotation of the conveying belt 300, the rubber 1400 moves while the pressing belt 500 rotates along the circumference under the guidance of the guide roller 400, and the rotation direction of the pressing belt 500 is opposite to that of the conveying belt 300.

[0065] The specific structure of the rack 100 is as follows Figure 2As shown, the rack 100 comprises two transverse section steels 110 distributed side by side in horizontal direction, the cooling pool 200 is fixed between the two transverse section steels 110, the lower part of the transverse section steel 110 is fixed with the foot section steel 120 distributed side by side along the length direction of the transverse section steel 110 and arranged vertically, the bottom end of the two foot section steels 120 below the feeding end of the conveying belt 300 is fixed and connected by the bottom strip 140, the upper part of the transverse section steel 110 is fixed with the vertical section steel 130 distributed side by side along the length direction of the transverse section steel 110 and arranged vertically, the end part of the vertical section steel 130 is fixed with the top rack 150.

[0066] The specific structure of the conveying belt 300 is shown in Figure 4 and Figure 5 As shown, the conveying belt 300 is a conveying net rack, so that the conveying belt 300 has dense mesh holes, which facilitates the inflow of cooling liquid, increases the contact area of the cooling liquid with the rubber 1400 on the conveying surface 301, and improves the heat exchange effect; the conveying surface 301 has a V-shaped structure, so that the two ends of the conveying surface 301 are higher than the middle part of the conveying surface 301, the middle part of the conveying surface 301 is concave and located in the cooling pool 200, the upper part of the two ends of the middle part is provided with the press wheel 310, the press wheel 310 rotates around its own axis line on the inner wall of the cooling pool 200 and the wheel surface is attached to the conveying surface 301, and the inner side of the conveying belt 300 is also provided with a rotating roller, which rotates around its own axis line on the rack 100, and the direction of the conveying belt 300 is guided by the rotating roller.

[0067] It should be noted that the conveying belt 300 is mainly used for conveying rubber 1400, and the conveying belt 300 preferably adopts a metal mesh belt, such as a stainless steel conveyor mesh chain produced by Chengdu Lixinfa Metal Mesh Co., Ltd., that is, a flat mesh chain type mesh metal conveying belt.

[0068] Further improvement is that the guide roller 400 comprises a lower pressing roller 410, which is movable in the cooling pool 200 to adjust the gap between the pressing belt 500 and the conveying surface 301, and the lower pressing roller 410 is connected with a positioning assembly 440 for positioning the axial height position of the lower pressing roller 410.

[0069] The lower pressing roller 410 is movable in the inner side of the cooling pool 200, which can adjust the height position of the lower pressing roller 410 according to the production needs of the rubber 1400, so as to change the gap between the pressing belt 500 and the conveying surface 301, and lock the height position of the axis line of the lower pressing roller 410 through the positioning assembly 440, so that the lower pressing roller 410 can stably rotate around its own axis line, and ensure the stable rotation of the pressing belt 500 and the conveying belt 300, so as to realize the stable transmission of the rubber 1400.

[0070] Specifically, the positioning assembly 440 comprises a positioning arm 441 and a positioning screw 442, the down roller 410 is rotatable around the axis of the down roller 410 on the positioning arm 441, and the positioning screw 442 is threadedly connected with the positioning arm 441 and abuts against the rack 100; the down roller 410 and the rack 100 are further provided with a swing arm 450, the swing arm 450 is rotatably connected with the guide roller 400 and the rack 100 at two ends thereof and the rotational axes of the two ends are parallel to the axial direction of the guide roller 400.

[0071] As shown in Figure 1 , Figure 1 (A) and Figure 5 , the down roller 410 is provided with the positioning assembly 440 and the swing arm 450 at both ends of the roller shaft, the two swing arms 450 are provided with a center roller 480 between the end portions away from the down roller 410, the center roller 480 is located above the side of the down roller 410, the two ends of the center roller 480 are fixedly connected with the two transverse steel bars 110 through two center bearings 481, the inner ring of the center bearing 481 is fixedly connected with the roller shaft of the center roller 480, and the outer ring is fixed above the transverse steel bar 110, so that the down roller 410 can rotate around the axis of the center roller 480 as the center line.

[0072] The positioning arm 441 is L-shaped and comprises a vertical arm and a horizontal arm, the vertical arm is vertically arranged adjacent to the inner wall of the cooling pool 200, and the horizontal arm is horizontally arranged above the transverse steel bar 110 and threadedly connected with the positioning screw 442, the axial direction of the positioning screw 442 is vertical, and the positioning screw 442 abuts against the upper side of the transverse steel bar 110.

[0073] In the above structure, the down roller 410 abuts against the transverse steel bar 110 through the bottom of the positioning screw 442, so as to fix the height position of the axis of the down roller 410, and the down roller 410 guides the running direction of the compression belt 500, so that there is a gap between the compression belt 500 and the conveying surface 301 for the rubber 1400 to pass through; when it is necessary to adjust the height position of the down roller 410 and to lock the height, the positioning screw 442 at both ends is rotated, so as to adjust the height position of the horizontal arm in the positioning arm 441, and the height position and the horizontal position of the positioning arm 441 are changed in the process that the horizontal arm moves axially relative to the positioning screw 442, and the down roller 410 can swing around the axis of the center roller 480 as the center line, so as to adjust and fix the height position of the axis of the down roller 410.

[0074] As shown in Figure 1 , Figure 2 and Figure 5As shown, the guide roller 400 in the pressing assembly further comprises two fixed rollers 420 and a pressing roller 430, both ends of the guide roller 400 are provided with connecting bearings 401, and the connecting bearings 401 corresponding to the fixed rollers 420 are arranged on the rack 100; the top of the vertical profile steel 130 adjacent to the discharge end of the conveying belt 300 is provided with a second opening 131 extending in the vertical direction, the vertical profile steel 130 is fixed with a horizontal plate 180, the roller shafts of the pressing roller 430 are arranged on the inner side of the second opening 131, and the connecting bearings 401 corresponding to the ends of the roller shafts of the pressing roller 430 are connected with an adjusting screw 460 extending vertically upward and penetrating through the horizontal plate 180, the adjusting screw 460 is threadedly connected with an adjusting nut 470, and the adjusting nut 470 abuts against the upper side of the horizontal plate 180.

[0075] After the above structure is adopted, the pressing roller 430 penetrates through the second opening 131 and can move in the vertical direction, the position of the pressing roller 430 is fixed by abutting the adjusting nut 470 against the upper side of the horizontal plate 180, and thus the position of the pressing roller 430 can be adjusted and fixed, so that the conveying belt 500 can be kept in the tension state, which is beneficial to stably press the rubber 1400 on the conveying belt 300 and ensure the stable rotation of the conveying belt 500.

[0076] Further improvement is that the conveying belt 300 further comprises a heat dissipation part 302, both ends of the heat dissipation part 302 are connected with both ends of the conveying surface 301, the heat dissipation part 302 is arranged below the cooling pool 200, a water storage pool 700 is arranged below the heat dissipation part 302, and a reflux pump 710 is arranged between the water storage pool 700 and the cooling pool 200.

[0077] After the above structure is adopted, the conveying belt 300 keeps rotating to drive the rubber 1400 to move, and at the same time, part of the conveying belt 300, i.e. the heat dissipation part 302, is located below the cooling pool 200, the cooling liquid adhered by the heat dissipation part 302 is divided into two parts, one part falls downward and enters the water storage pool 700, and the other part evaporates to absorb the heat of the heat dissipation part 302 to cool the heat dissipation part 302, and then the conveying belt 300 continues to rotate, and the cooled part enters the cooling pool 200, so that the heat absorbed by the conveying belt 300 from the rubber 1400 can be dissipated to the air, the continuous heating speed of the cooling liquid in the conveying belt 300 and the cooling pool 200 is slowed down, and a certain temperature difference is ensured between the cooling liquid and the rubber 1400 to improve the cooling efficiency.

[0078] The cooling liquid accumulated in the water storage pool 700 is also convenient for cooling, and when the cooling liquid accumulated in the water storage pool 700 reaches a certain amount, the reflux pump 710 is started to reflux the low-temperature cooling liquid accumulated in the water storage pool 700 to the cooling pool 200.

[0079] Further improvement is that the heat exchange pipe 720 is arranged in the water storage pool 700. By passing low-temperature heat exchange liquid into the heat exchange pipe 720, the heat exchange liquid exchanges heat with the cooling liquid, absorbs the heat of the cooling liquid, so that the cooling liquid is rapidly cooled and then is extracted by the backflow pump 710 and supplemented into the cooling pool 200.

[0080] Further improvement is that the heat dissipation part 302 is provided with the guide plate 800 below both ends, and the guide plate 800 is used for guiding the cooling liquid dripping on the heat dissipation part 302 into the water storage pool 700. The guide plate 800 is an inclined downward guide groove, the lower end of the guide groove is located directly above the water storage pool 700, the projection of the guide groove and the water storage pool 700 on the horizontal plane is a first projection, the projection of the heat dissipation part 302 on the horizontal plane is a second projection, and the second projection is located in the first projection. In this way, when the high-temperature cooling liquid dripping on the heat dissipation part 302 falls downward, it enters the water storage pool 700 and falls on the guide plate 800, slides downward along the inclined downward guide plate 800, and finally enters the water storage pool 700. In this way, the cooling liquid dripping on the ground is avoided, and the production environment is not polluted. Furthermore, when the cooling liquid flows downward along the guide plate 800, the guide plate 800 can also absorb the heat of the cooling liquid, so that the cooling liquid is further cooled before entering the water storage pool 700, and the guide plate 800 dissipates the absorbed heat to the outside. In this way, the cooling liquid dripping on the guide plate 800 and flowing downward is continuously cooled.

[0081] Specifically, as shown in Figures 1-2 、 Figure 4 、 Figure 4 (A), Figure 6 and Figure 6 (A), the rotating rollers inside the conveying belt 300 include three traction rollers 320, both ends of the three traction rollers 320 are provided with traction bearings 321, two of the three traction rollers 320 are located above both ends of the transverse shaped steel 110, the traction bearings 321 corresponding to the two traction rollers 320 are arranged on the rack 100, and the remaining one traction roller 320 is located between the cooling pool 200 and the water storage pool 700, and the traction bearing 321 corresponding to the remaining one traction roller 320 is arranged above the water storage pool 700.

[0098] Specifically, the shaping belt 510 is a rubber belt, and the circumferential inner wall and circumferential outer edge of the shaping belt 510 are fixedly connected with the sponge belt 520.

[0099] After the above structure is adopted, the pressing belt 500 has a three-layer structure, the middle layer is a rubber layer, which plays a basic shaping role, and the inner and outer two layers are sponge layers, so that the inner and outer surfaces of the pressing belt 500 are more elastic and soft, and the pressing belt 500 can be stably rotated around its circumferential direction through the rotation of the guide roller 400; Furthermore, the sponge belt 520 also has a water absorption function, and during the circumferential rotation of the pressing belt 500, the sponge belt 520 can absorb the cooling liquid to take the cooling liquid away from the cooling liquid level in the cooling pool 200, and the cooling liquid absorbed by the sponge belt 520 is in contact with the air outside to exchange heat, thereby avoiding the continuous and rapid heating of the cooling liquid, so that the device is more suitable for the continuous cooling of the batch of rubber 1400, and ensures the good cooling effect of the device after long-term operation, avoiding the heat absorbed by the cooling liquid from being discharged, resulting in a continuous decline in the heat exchange effect of the rubber 1400.

[0100] Third embodiment

[0101] As shown in Figures 9-11 The rubber cooling system of the third embodiment of the present application is based on the second embodiment, and the difference lies in that the discharge end of the conveying surface 301 is immediately above the extrusion roller 1100 which is coaxial with the width direction of the conveying belt 300, the extrusion roller 1100 rotates around its axis on the frame 100, and the pressing belt 500 is clamped between the conveying belt 300 and the extrusion roller 1100.

[0102] When the sponge belt 520 absorbs part of the heated coolant and moves upward, the sponge belt 520 is extruded by the extrusion roller 1100 below the extrusion roller 1100 and the conveying belt 300, and the extrusion roller 1100 and the conveying belt 300 cooperate with each other to extrude the part of the coolant absorbed by the sponge belt 520, so that the extruded coolant flows into the cooling pool 200 in the opposite direction of the movement direction of the extrusion belt 500, and the remaining coolant in the sponge belt 520 continues to exchange heat with air to be cooled. By extruding the part of the coolant absorbed by the sponge belt 520, the extruded coolant first falls on the conveying surface 301 of the conveying belt 300 and flows downward from the discharge end to the cooling pool 200, and in this flowing process, the coolant falling on the conveying belt 300 exchanges heat with the air above the side of the cooling pool 200 to improve the cooling effect of the coolant, so that the cooled coolant enters the cooling pool 200.

[0103] Further improvement is that the extrusion roller 1100 is connected with an elastic extension unit 1300, and the elastic extension unit 1300 is arranged on the rack 100 and is used to drive the extrusion roller 1100 to abut against the extrusion belt 500.

[0104] Specifically, the vertical steel 130 is provided with a fourth opening 132 extending in the vertical direction, the roller shaft of the extrusion roller 1100 penetrates the inside of the fourth opening 132 and is connected with a sliding bearing 1120, the upper side of the sliding bearing 1120 is fixed with a horizontal sliding plate 1130, the two ends of the sliding plate 1130 are connected with the elastic extension unit 1300, the elastic extension unit 1300 includes a sliding rod 1320 fixed to the upper side of the sliding plate 1130 and extending upward, a convex plate 1340 arranged at the top end of the sliding rod 1320, a sliding sleeve 1330 fixed to the upper side of the vertical steel 130 and slidingly matched with the sliding rod 1320, and a compression spring 1310 clamped between the sliding sleeve 1330 and the sliding plate 1130.

[0105] After the above structure is adopted, the sliding rod 1320 and the sliding plate 1130 have a downward moving trend by the downward elastic force of the compression spring 1310, which acts on the sliding bearing 1120, so as to drive the extrusion roller 1100 to have a downward moving trend and abut against the inner wall of the extrusion belt 500, i.e., the inner sponge belt 520, so that the extrusion roller 1100 can act on the extrusion belt 500 to extrude the coolant absorbed by the sponge belt 520.

[0106] Further improvement is that the circumferential outer edge and the circumferential inner wall of the shaping belt 510 are both provided with the sponge belt 520, the shaping belt 510 is provided with a plurality of communication holes 511 distributed along the circumferential direction, and the sponge belt 520 is arranged in the communication holes 511. Figure 11As shown, since the plurality of communication holes 511 are arranged on the shaping belt 510, spaces are reserved on the shaping belt 510 for communication between the inner and outer sides of the shaping belt 510, which on one hand reduces the amount of production material and lowers the production cost, and on the other hand, when absorbing the cooling liquid, the communication holes 511 can pre-store the cooling liquid, increasing the amount of absorbed cooling liquid; when the pressing belt 500 is extruded, the sponge belt 520 on the inner and outer sides of the shaping belt 510 is extruded, and the deformed part enters the communication hole 511 to extrude the space of the cooling liquid, so as to extrude more cooling liquid.

[0107] Further improvement is that the circumferential outer edge of the extrusion roller 1100 is provided with symmetrical distributed spiral protrusions 1110, and the symmetrical distribution surface is located between the two sides of the pressing belt 500; during the rotation of the conveying belt 300, the spiral protrusions 1110 which are symmetrically distributed and rotate around the axis of the extrusion roller 1100 apply extrusion forces in opposite directions and face away from each other to the pressing belt 500, so as to extrude the cooling liquid absorbed by the sponge belt 520 from the center of the pressing belt 500 to the two sides.

[0108] In the present application, the pressing belt 500 has two, which are distributed along the axis of the downward pressing roller 410, and correspondingly, Figure 10 As shown, the circumferential outer edge of the extrusion roller 1100 is provided with two pairs of spiral protrusions 1110, and the two pairs of spiral protrusions 1110 each include two spiral protrusions 1110 which are symmetrically distributed, i.e. the rotation directions of the two spiral protrusions 1110 are opposite. During the rotation of the conveying belt 300, the extrusion roller 1100 rotates, and the two spiral protrusions 1110 rotate synchronously and extrude the sponge belt 520; since the rotation directions are opposite, the spiral protrusions 1110 extrude the cooling liquid absorbed by the sponge belt 520 in opposite directions, and by controlling the specific rotation directions of the two spiral protrusions 1110, the cooling liquid absorbed by the sponge belt 520 can be extruded from the center of the pressing belt 500 to the two sides, thereby enhancing the water extrusion effect.
