Description

Technical Field

[0001] The utility model relates to the technical field of tile granulators, in particular to a hopper structure of a granulator. Background Art

[0002] At present, the working process of the tile granulator is mainly divided into the process of laying the powder, the process of rolling and compacting the powder, and the process of crushing and granulating the compacted powder to obtain large-granular tile powder for subsequent tile production. In the crushing and granulation process, it is mainly completed by the hopper device of the granulator. For example, the Chinese patent literature discloses a patent application number 202023028805.7, named "A granulator" technical solution, which mainly includes a frame, a splash-proof frame and a material receiving funnel arranged on the frame in an upper and lower arrangement, and a scraper assembly arranged in the material receiving funnel, wherein the scraper assembly includes a particle size screen, a scraper rotating shaft, a scraper plate and a scraper driver, and a U-shaped opening is provided on one side of the material receiving funnel to form an inspection port, and the upper cover of the inspection port is equipped with a baffle plate. During use, when the scraper assembly needs to be replaced or cleaned, there is no need to disassemble the splash-proof frame, the receiving funnel and the frame. Only the baffle plate needs to be disassembled to open the inspection port for maintenance. However, in actual application, this technical solution still has the following shortcomings:

[0003] First, in actual manufacturing, the splash-proof frame, the receiving funnel and the frame are usually welded together and maintained only through the inspection port. During maintenance, it is necessary to first remove the baffle plate and then remove the particle size filter before replacement and maintenance can be performed. The operation is very complicated and cumbersome and inconvenient. Secondly, the inspection port is set on one side of the receiving funnel, and workers need to squat to operate it, which is more tiring than standing and very uncomfortable. At the same time, under the obstruction of the splash-proof frame and the other three sides of the receiving funnel, the lighting inside the hopper device is seriously insufficient, and workers need to hold or wear flashlights to operate, which increases the difficulty of replacement and maintenance.

[0004] Therefore, in view of the above-mentioned deficiencies of the hopper device of the above-mentioned granulator, it is very necessary to make further improvements to its structure in order to better meet people's application needs. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems and shortcomings, and to provide a hopper structure of a granulator. When replacing and maintaining the hopper structure, the splash-proof frame only needs to be removed, so that the movable scraping end of the scraping assembly can be exposed outside the receiving hopper, so that workers can stand to operate, and maintenance is more convenient and comfortable. In addition, during the maintenance process, there is no splash-proof frame to block the light, and there is sufficient lighting for workers to perform maintenance operations, which greatly reduces the difficulty of replacement and maintenance.

[0006] The technical solution of the present utility model is realized as follows: A hopper structure of a granulator, including a frame with a material receiving funnel, a scraping assembly disposed in the material receiving funnel, and a splash-proof frame body disposed above the material receiving funnel. The feature is that a circular limiting trough for inserting the splash-proof frame body and limiting its position is provided at the top end of the material receiving funnel, and the bottom of the circular limiting trough is communicated with the interior of the material receiving funnel. The splash-proof frame body is detachably inserted into the circular limiting trough; the movable scraping ends of the scraping assembly rotate and swing back and forth in the material receiving funnel, the circular limiting trough and the splash-proof frame body.

[0007] Preferably, the present utility model further includes two rotation limiting members with swing arms. Latching portions that rest on the frame are respectively provided on the left and right sides of the splash-proof frame body. The two rotation limiting members are respectively rotatably disposed on the left and right sides of the frame, and their swing arms can swing above the latching portions as the rotation limiting members rotate, so that the latching portions are limited between the swing arms and the frame.

[0008] Preferably, the present utility model further includes locking screws. Through holes are provided on the rotation limiting members, and one end of the locking screws passes through the through holes and is locked on the frame.

[0009] Preferably, damping rubber pads that contact the latching portions are further provided on the swing arms.

[0010] Preferably, handle portions are respectively provided on the left and right sides of the splash-proof frame body.

[0011] Preferably, the material receiving funnel is provided with a material receiving cavity penetrating through its top and bottom surfaces. Two supporting portions arranged at intervals in the front and rear are provided at the upper end of the material receiving cavity. The circular limiting trough is jointly formed by the upper end of the material receiving cavity and the two supporting portions; the scraping assembly is disposed in the material receiving cavity.

[0012] Preferably, the supporting portion is composed of a transverse supporting plate portion and a vertical limiting plate portion connected together, and the upper end surface of the vertical limiting plate portion extends to the top surface of the material receiving funnel.

[0013] Advantages of the present utility model: Since the splash-proof frame of the present utility model is installed above the material receiving funnel in a detachable manner, and the movable scraping ends of the scraping assembly rotate and swing back and forth in the material receiving funnel, the annular limiting trough and the splash-proof frame. During replacement and maintenance, only by detaching the splash-proof frame from the material receiving funnel can the movable scraping ends of the scraping assembly be exposed outside the material receiving funnel, so that workers can operate while standing, and the maintenance is more convenient and comfortable. Moreover, during the maintenance process, the movable scraping ends of the scraping assembly can be exposed outside the material receiving funnel, and there is no splash-proof frame blocking the light, so there is sufficient lighting for workers to perform maintenance operations, thereby greatly reducing the difficulty of replacement and maintenance. In addition, by providing the annular limiting trough, the periphery of the splash-proof frame can be annularly limited, so that it can be detachably connected to the material receiving funnel and is not easily loosened and dropped, ensuring the use reliability of the hopper structure.

[0018] As Figure 1 shown in Figure 2 A hopper structure of a granulator according to the present utility model includes a frame 1 with a material receiving funnel 2, a scraping assembly 3 disposed in the material receiving funnel 2, and a splash-proof frame 4 disposed above the material receiving funnel 2. To achieve the purpose proposed by the present utility model, the top end of the material receiving funnel 2 is provided with an annular limiting trough 21 for inserting the splash-proof frame 4 and limiting the position of the splash-proof frame 4, and the bottom of the annular limiting trough 21 is in through communication with the inside of the material receiving funnel 2. The splash-proof frame 4 is detachably inserted into the annular limiting trough 21; the movable scraping ends of the scraping assembly 3 rotate and swing back and forth in the material receiving funnel 2, the annular limiting trough 21 and the splash-proof frame 4. During replacement and maintenance of the present utility model, only by removing the splash-proof frame 4 can the movable scraping ends of the scraping assembly 3 be exposed outside the material receiving funnel 2, so that workers can operate while standing, and the maintenance is more convenient and comfortable. And during the maintenance process, there is no splash-proof frame 4 blocking the light, and there is sufficient lighting for workers to perform maintenance operations, greatly reducing the difficulty of replacement and maintenance.

[0019] In order to enable the splash-proof frame 4 to be stably installed on the material receiving funnel 2, not easily loosen, and be convenient to disassemble, as Figure 1 shown in Figure 3 the figure, the present utility model further includes two rotation limiting members 5 with swing arms 51. Latching portions 41 that lean on the frame 1 are respectively provided on the left and right sides of the splash-proof frame 4. The two rotation limiting members 5 are respectively rotatably arranged on the left and right sides of the frame 1, and their swing arms 51 can swing above the latching portions 41 as the rotation limiting members 5 rotate, so that the latching portions 41 are limited between the swing arms 51 and the frame 1. In this way, not only can the splash-proof frame 4 be stably installed on the material receiving funnel 2, but also the disassembly is very convenient, without the need to use other tools, and the use is very reliable.

[0020] In order to further improve the installation structure of the rotation limiting member 5, as Figure 3 shown in the figure, the present utility model further includes a locking screw 6. A through hole 52 is provided on the rotation limiting member 5, and one end of the locking screw 6 passes through the through hole 52 and is locked on the frame 1. In this way, not only can the rotation limiting member 5 be installed on the frame 1, but also the rotation of the rotation limiting member 5 is not affected.

[0021] As Figure 3 shown in the figure, a damping rubber pad 53 that contacts the latching portion 41 is further provided on the swing arm 51. In this way, the contact area and friction between the swing arm 51 and the latching portion 41 can be increased, the contact is made closer, and it will not loosen randomly, improving the reliability of the connection structure.

[0022] As Figure 3 shown in the figure, lifting handles 42 are respectively provided on the left and right sides of the splash-proof frame 4. In this way, when disassembling the splash-proof frame 4, the splash-proof frame 4 can be easily lifted.

[0023] In order to further improve the structure of the material receiving funnel 2 and the annular limiting trough 21, as Figure 2 shown in the figure, the material receiving funnel 2 is provided with a material receiving cavity 22 that penetrates its top surface and bottom surface. Two supporting portions 23 arranged at intervals front and back are provided at the upper end of the material receiving cavity 22, and the annular limiting trough 21 is jointly formed by the upper end of the material receiving cavity 22 and the two supporting portions 23. That is: the annular limiting trough 21 and the material receiving cavity 22 are arranged in a communicating manner. Specifically, the scraping component 3 is arranged in the material receiving cavity 22. In this way, the structure of the annular limiting trough 21 can be very easily made on the material receiving funnel 2.

[0024] In order to further improve the structure of the supporting portion 23, as Figure 4As shown in the figure, the supporting part 23 is composed of a horizontal supporting plate part 231 and a vertical limiting plate part 232 connected together, and the upper end surface of the vertical limiting plate part 232 extends to the top surface of the material receiving funnel 2. The horizontal supporting plate part 231 is used to support the splash-proof frame 4, and the vertical limiting plate part 232 is used to limit the position of the splash-proof frame 4. In the actual application process, the horizontal supporting plate part 231 and the vertical limiting plate part 232 can be directly connected by welding to form the L-shaped supporting part 23, or extension parts 233 can be respectively arranged on the horizontal supporting plate part 231 and the vertical limiting plate part 232, and then the two extension parts 233 are locked together by bolts 234 to form the supporting part 23.

[0025] In the actual application process, the supporting part 23 is fixed on the material receiving funnel 2 by welding.

[0026] In the actual application process, such as Figure 1 As shown in the figure, an inspection opening 24 penetrating into the material receiving cavity 22 is reserved on one side surface of the material receiving funnel 2 of the present utility model, and a baffle plate 25 is covered on the inspection opening 24. This can not only facilitate the replacement of the particle size sieve of the scraping component 3, but also obtain more daylight after removing the baffle plate 25 and the splash-proof frame 4, making the maintenance operation easier.

[0027] In order to further improve the structure of the scraping component 3, as Figure 2 shown in the figure, the scraping component 3 includes a particle size sieve 31, a scraping rotating shaft 32, a plurality of scraping plates 33, a plurality of connecting arms 35, and a scraping driving motor 34. The particle size sieve 31 is installed in the material receiving cavity 22 of the material receiving funnel 2 from the inspection opening 24. The scraping driving motor 34 is installed on the outer side wall of the material receiving funnel 2. The scraping rotating shaft 32 penetrates into the material receiving cavity 22 and one end of it is connected to the power output end of the scraping driving motor 34. Each scraping plate 33 is connected to the scraping rotating shaft 32 through each connecting arm 35. Specifically, the movable scraping end of the scraping component 3 is the scraping plate 33.

[0028] Note: The use process and principle of the specific structure of the scraping component 3 are recorded in the technical solution with the Chinese patent application number 202023028805.7 and the name "A granulator", and will not be elaborated here too much.
