Description

Technical Field

[0001] The utility model relates to the technical field of rubber mixing, in particular to a cooling device for mixing rubber sheets. Background Art

[0002] Rubber mixing refers to the process of refining raw rubber or rubber compounds in a mixer. After the mixer mixes the rubber compounds to form rubber sheets, the rubber sheets need to be cooled.

[0003] At present, the cooling of rubber compounds is generally carried out by directly immersing them in cooling water. After water cooling, it is also necessary to remove the water remaining on the rubber sheets at the same time, otherwise it will affect the subsequent processing of the rubber sheets. For example, the invention patent with the publication number CN108748768A discloses a rapid cooling device for mixing rubber sheets. In this device, after the rubber sheets are cooled by immersion in water, they will be placed in a drying box and air-dried. However, the problem of this device is that the air-drying process takes a long time, and a drying box with a long floor area is required to achieve the air-drying purpose. Therefore, it is difficult to meet the existing needs. And there are also devices on the market that dry rubber sheets by hot air. However, when the temperature of the hot air is low, the drying efficiency cannot be significantly improved, and when the temperature of the hot air is high, it may cause the rubber sheets to denature in a high-temperature environment, thus affecting the quality of the rubber sheets. Therefore, it is difficult to effectively and safely remove the water on the rubber sheets quickly. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to clearly and completely describe the purpose and technical solution of the utility model and more clearly explain its advantages, the following further details the embodiments of the utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the utility model, rather than all of the embodiments, and are only used to explain the embodiments of the utility model, not to limit the embodiments of the utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the utility model.

[0026] [[ID=^37]]Embodiment 1: Please refer to Figures 1 to 5, the utility model provides a cooling device for mixing rubber sheets, which includes a frame 1 and a water removal device 4. The frame 1 is provided with a drying chamber 15 and a water storage chamber 13 that are isolated from each other from top to bottom, and the drying chamber 15 and the water storage chamber 13 are connected through a connecting chamber 14. The water storage chamber 13 is filled with cooling water, and the rubber sheet 10 sequentially passes through the water storage chamber 13, the connecting chamber 14 and the drying chamber 15 and moves forward at a uniform speed. A pair of discharge rollers 9 for clamping and driving the movement of the rubber sheet 10 are installed at the outlet end of the drying chamber 15, and a second driving motor 11 for driving the discharge rollers 9 is installed on the frame 1. A pair of feeding rollers 17 for clamping and driving the movement of the rubber sheet 10 are installed at the inlet end of the drying chamber 15, and a first driving motor 5 for driving the rotation of the feeding rollers 17 is installed on the frame 1. A feeding roller 12 for carrying the rubber sheet 10 is installed at the inlet end of the water storage chamber 13, and at least two reversing rollers 16 for reversing the movement direction of the rubber sheet 10 are installed in the water storage chamber 13. Driven by the discharge rollers 9 and the feeding rollers 17, the rubber sheet 10 can pass through the inside of the water storage chamber 13 and be cooled by the cooling water, and then the rubber sheet 10 passes through the drying chamber 15 and is dried.

[0027] Please refer to Figures 1 to 5, at least two pairs of water removal devices 4 are installed at the upper and lower ends of the drying chamber 15 corresponding to the film 10. The water removal device 4 includes a mounting base 407 installed on the frame 1, and a closed housing 406 is installed on the mounting base 407. A rotating shaft 408 for squeezing the film 10 is rotatably installed in the installation cavity 405 of the closed housing 406. Guide grooves 409 are arranged in a circumferential array on the rotating shaft 408. A top plate 411 is installed in the guide groove 409 through a top spring 412, and a water-absorbing cotton 410 for absorbing the water on the surface of the film 10 is installed on the top plate 411. A roller motor 414 for driving the rotation of the rotating shaft 408 is installed on the mounting base 407, and an exhaust pump 402 for evacuating the installation cavity 405 to a negative pressure state is installed on the mounting base 407. A heating drum 404 is rotatably installed in the installation cavity 405, and heat-conducting teeth 403 that are integrally formed on the heating drum 404 and engage with the guide grooves 409 and are used to heat the water-absorbing cotton 410 are provided. The bottom of the closed housing 406 is attached and sealed to the surface of the rotating shaft 408 through a rubber pad, and the heating drum 404 is a metal drum. The heating drum 404 is installed on the mounting base 407 through a bearing, and a heater 413 is provided on the mounting base 407. A heat-conducting rod 401 that is inserted into the central axis of the heating drum 404 and heats the heating drum 404 is provided at the heat output end of the heater 413, and the heat-conducting rod 401 is heated by an electric heating wire or a high-frequency heating coil in the heater 413. When the roller motor 414 drives the rotation of the rotating shaft 408, the top plate 411 located below the rotating shaft 408 will be ejected by the top spring 412, so that the water-absorbing cotton 410 can be attached to the surface of the film 10. Subsequently, after the water-absorbing cotton 410 absorbs the water on the film 10, it will continue to rotate along the rotating shaft 408 until it moves to a position where it engages with the heat-conducting teeth 403. The heat-conducting teeth 403 will be inserted into the guide groove 409 and fit with the water-absorbing cotton 410, so that the water in the water-absorbing cotton 410 is heated and evaporated into the installation cavity 405. Subsequently, the water vapor in the installation cavity 405 is pumped out by the exhaust pump 402.In the above process, since the rotating shaft 408 and the heat-conducting teeth 403 are meshed and installed, when the rotating shaft 408 rotates, it will drive the heating drum 404 to move. The heat generated by the heater 413 will be transferred to the heating drum 404 through the heat-conducting rod 401, then transferred from the heating drum 404 to the heat-conducting teeth 403, and then the heat-conducting teeth 403 transfer the heat to the water on the absorbent cotton 410 to complete the evaporation process. In this process, the heat-conducting teeth 403 do not need to be in direct contact with the film 10, so the heat-conducting teeth 403 can heat the absorbent cotton 410 at a temperature above 100 degrees Celsius. When the absorbent cotton 410 leaves the heat-conducting teeth 403, due to the evaporation of water and natural cooling, the temperature of the absorbent cotton 410 will be significantly lower than that of the heat-conducting teeth 403. At the same time, because the contact time between the absorbent cotton 410 and the surface of the film 10 is short and the heat conduction efficiency is low, the absorbent cotton 410 cannot scald the surface of the film 10. Thus, it can neither damage the surface of the film 10 nor improve the efficiency of water evaporation. Moreover, the residual heat on the absorbent cotton 410 can directly accelerate the evaporation of the water on the film 10, further improving the efficiency of water removal. At the same time, it also shortens the time required for the film 10 to stay in the drying chamber 15, so it can effectively save the space in the drying chamber 15 and make the overall structure of the film 10 cooling device more compact. And each water removal device 4 works independently, so that the heating temperature of each heat-conducting tooth 403 on the absorbent cotton 410 can be controlled separately. In this way, it can be avoided that when the absorbent cotton 410 closer to the discharge roller 9 cannot absorb water, there is too much residual heat on the surface, which scalds the film 10. Therefore, it is safer and more reliable to use, and the absorbent cotton 410 can also be replaced with other absorbent materials such as sponge according to the use needs. Thus, the problem that the existing film cooling equipment cannot quickly and safely remove the residual water on the film is solved, and the processing efficiency of the film can be effectively improved.

[0028] Embodiment 2: Please refer to Figure 3 and Figure 6, on the basis of the first embodiment, a water scraping device 2 for scraping water on the film 10 is arranged in the connection cavity 14. The water scraping device 2 includes a mounting frame 202 fixed in the connection cavity 14, and a guide rod 201 is arranged in the mounting frame 202. A scraping plate 203 for clamping the film 10 is slidably mounted on the guide rod 201. An extrusion spring 204 is installed between the scraping plate 203 and the mounting frame 202. When the film 10 passes between the two scraping plates 203, since the two scraping plates 203 are tightly pressed on the surface of the film 10 under the extrusion of the extrusion spring 204, the water on the surface of the film 10 will be scraped off from the surface of the film 10 by the scraping plate 203 and fall back into the water storage cavity 13 for recycling. The surface moisture of the film 10 after being scraped by the water scraping device 2 is greatly reduced, and the moisture can be dried more quickly in the dryer. In order to better scrape the water on the film 10, the surface of the scraping plate 203 can be made of materials such as rubber or sponge to contact the surface of the film 10 and perform the task of scraping water.

[0029] Embodiment Three: Please refer to Figures 1 to 3 , on the basis of the second embodiment, an exhaust port 7 communicating with the drying cavity 15 is arranged on the frame 1, and an air spraying pipe 3 for spraying air to cool the surface of the rotating shaft 408 and the film 10 is arranged in the drying cavity 15. An air filtering box 6 is fixedly installed on the frame 1, and the output end of the air filtering box 6 is connected to the air spraying pipe 3 through an air supply pump 8. An initial effect filter screen is installed at the inlet end of the air filtering box 6, and a dust removal cloth bag for filtering air is arranged in the air filtering box 6. The air supply pump 8 can send the clean air filtered by the air filtering box 6 into the drying cavity 15 through the air spraying pipe 3, and then use the clean air to cool the surfaces of the film 10 and the rotating shaft 408, so as to ensure that the surfaces of the film 10 and the rotating shaft 408 are within a suitable temperature range, avoid the film 10 being scalded by the residual heat on the water absorbing cotton 410, and at the same time, the increased air flow rate can also be used to assist the water on the film 10 to evaporate quickly and be discharged through the exhaust port 7. Therefore, the efficiency of removing water on the film 10 can be further increased.
