[0001] The utility model relates to the technical field of double-roller dryers, and specifically relates to a double-roller dryer. Background Technique
[0002] The double-roller dryer is a drying device widely used in industries such as food, chemical industry, and medicine, and is mainly used for drying liquid materials. It consists of two relatively rotating drums. By heating the drum surface to evaporate the liquid, the materials are dried. During the operation of the double-roller dryer, the materials are coated on the drum surface through the gap between the two drums, and after heating and drying, a flaky dried product is formed.
[0003] In the existing device, in order to form a film body by spraying liquid between the two drums and also to better use the scraper to scrape off the dried materials, the distance between the drums needs to be adjusted. In order to form film body materials with different thicknesses and at the same time avoid the film body from not forming, after the drums are installed in the existing device, the distance between the cylinders cannot be adjusted subsequently. The adjustment can only be carried out by disassembling and reinstalling, which will greatly reduce the overall working efficiency of the device.
[0004] Therefore, it is necessary to design a double-roller dryer to solve the above problems. Content of the Utility Model
[0005] The purpose of the utility model is to provide a double-roller dryer for solving the technical problems proposed in the above background technique.
[0006] In order to achieve the above purpose, the utility model provides the following technical solution: A double-roller dryer, including a box body, a feed port is opened at the top of the box body, and a first box body and a second box body are respectively fixedly connected to both sides of the box body. A sliding driving mechanism is arranged inside the first box body, and two symmetrical equipment boxes are fixedly connected to the sliding driving mechanism. Two sliding blocks are slidably arranged inside the second box body, and two symmetrical sliding ports are opened on both sides of the box body and on one side of the first box body and the second box body.

A drum is fixedly sleeved on both of the third rotating shafts inside the box body. Second bevel gears are fixedly connected to one ends of both of the third rotating shafts inside the second box body. A second servo motor is fixedly connected to one side of the first box body. A first rotating shaft is fixedly connected to the output shaft of the second servo motor. A plug-in member is fixedly connected to one end of the first rotating shaft. Second rotating shafts are rotatably connected to one side of both of the equipment boxes. First bevel gears are fixedly sleeved on one ends of the second rotating shafts adjacent to each other inside the equipment boxes, and a first bevel gear and a second bevel gear on the same side are meshed with each other. One end of the plug-in member is slidably inserted into the interiors of the two second rotating shafts.
[0007] Preferably, the sliding drive mechanism includes a first servo motor, the output shaft of the first servo motor is fixedly connected with a bidirectional threaded rod, both adjacent sides of the two equipment boxes are fixedly connected with threaded sleeve pieces, one end of the bidirectional threaded rod penetrates into the interiors of the two equipment boxes, and the two threaded sleeve pieces are respectively threadedly sleeved on both ends of the bidirectional threaded rod.
[0008] Preferably, the top and bottom of the equipment box are respectively in contact with the top and bottom of the inner cavity of the first box body, and the top and bottom of the sliding block are respectively engaged with the top and bottom of the second box body.

[0013] Through the movable insertion between the two second rotating shafts and the plug-in part, and the threaded connection between the bidirectional threaded rod and the two threaded sleeve pieces, when adjusting the distance between the two drums, the sliding arrangement of the two second rotating shafts on the plug-in part provides conditions for adjusting the distance between the two drums. When the second servo motor is turned on, the rotation of the plug-in part can still drive the two adjusted drums to rotate. The adjustment of the distance between the two drums will not affect the rotational direction of the two drums. Therefore, on the premise of not interfering with the rotation of the double drums, the distance between the two drums can still be adjusted, improving the overall working efficiency of the device.

Detailed implementation manner
[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0020] Obviously, many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the limitations of the specific embodiments disclosed in the following specification.
[0021] Please refer to Figures 1-4, the present utility model provides a double-drum dryer, which includes a box body 1. A feed inlet 2 is provided at the top of the box body 1, and a first box body 4 and a second box body 7 are respectively fixedly connected to both sides of the box body 1. A sliding driving mechanism is arranged inside the first box body 4, and two symmetrically arranged equipment boxes 9 are fixedly connected to the sliding driving mechanism. Two sliding blocks 17 are slidably arranged inside the second box body 7, and two symmetrically arranged sliding openings 18 are provided on both sides of the box body 1 and on one side of the first box body 4 and the second box body 7. A third rotating shaft 16 is rotatably connected between a second box body 7 and an equipment box 9 on the same side. Both of the two third rotating shafts 16 are fixedly sleeved with drums inside the box body 1. One end of both of the two third rotating shafts 16 inside the second box body 7 is fixedly connected with a second bevel gear 15. A second servo motor 6 is fixedly connected to one side of the first box body 4. The output shaft of the second servo motor 6 is fixedly connected with a first rotating shaft 11. One end of the first rotating shaft 11 is fixedly connected with a plug-in member 12. One side of each of the two equipment boxes 9 is rotatably connected with a second rotating shaft 13. One end of each of the two second rotating shafts 13 adjacent to each other inside the equipment box 9 is fixedly sleeved with a first bevel gear 14, and a first bevel gear 14 and a second bevel gear 15 on the same side are meshed with each other. One end of the plug-in member 12 is slidably inserted into the interiors of the two second rotating shafts 13. By changing the arrangement mode of the two drums, when the second servo motor 6 is started, the rotation of the first rotating shaft 11 drives the plug-in member 12 to rotate. The two second rotating shafts 13 will drive the two first bevel gears 14 to rotate through the rotation of the plug-in member 12. At this time, the two first bevel gears 14 will respectively drive the two second bevel gears 15 to rotate in opposite directions. At this time, the two drums can rotate in opposite directions. When the drums need to be adjusted, the sliding mechanism mentioned in the above description includes a first servo motor 5. When the first servo motor 5 is started, by the rotation of the bidirectional threaded rod 8, the relative or separated movement of the two threaded sleeve pieces 10 drives the two equipment boxes 9 to move towards each other or away from each other, so as to drive the two drums to adjust the distance through the two equipment boxes 9 and the two sliding blocks 17. Since one end of the plug-in member 12 is inserted into the interiors of the two second rotating shafts 13, at this time, the two second rotating shafts 13 will slide on the plug-in member 12, so as to cooperate with the distance adjustment of the two equipment boxes 9. And because the plug-in member 12 is always slidably connected with the two second rotating shafts 13, when the distance between the drums is adjusted, the start of the second servo motor 6 will not affect the subsequent rotation of the two drums. Therefore, the function of simply adjusting the distance between the two drums is realized without affecting the rotation of the two drums, and the overall working efficiency is improved.
[0022] In order to facilitate the stable sliding of the two equipment boxes 9 and the two sliding blocks 17 inside the first box body 4 and the second box body 7 respectively when the bidirectional threaded rod 8 rotates, the top and bottom of the equipment box 9 are respectively in contact with the top and bottom of the inner cavity of the first box body 4, and the top and bottom of the sliding block 17 are respectively engaged with the top and bottom of the second box body 7.
[0023] Further, in order to provide a sliding space for the two third rotating shafts 16 when the two third rotating shafts 16 slide, the two ends of the two third rotating shafts 16 are respectively slidably arranged inside the two sliding ports 18 on the same side.
[0024] Furthermore, in order to facilitate the stable sliding of the two second rotating shafts 13 towards or away from each other on the plug-in member 12 when adjusting the distance between the two rollers, the shape of the plug-in member 12 is cross-shaped, there is a distance between the two second rotating shafts 13, and there is a distance between one end of the first rotating shaft 11 and one end of one second rotating shaft 13.
[0025] In order to rotatably connect the two second rotating shafts 13 and the two first bevel gears 14 more stably, one end of each of the two second rotating shafts 13 is rotatably arranged on the adjacent side of the two equipment boxes 9 through bearings, and the bidirectional threaded rod 8 is located above the plug-in member 12.
[0026] The preferred embodiments of the present invention have been described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solutions of the present invention, and these simple modifications all belong to the protection scope of the present invention.
[0027] In addition, it should be noted that, in the case of no contradiction, the various specific technical features described in the above specific embodiments can be combined in any suitable way. To avoid unnecessary repetition, the present invention will not separately describe various possible combination methods.
[0028] In addition, any combination can be made between various different embodiments of the present invention as long as it does not violate the idea of the present invention, and it should also be regarded as the content disclosed by the present invention.
