DETAILED DESCRIPTION

[0030] The application will be further described in detail below in combination with all the drawings.

[0031] The application discloses a raw material grinding and granulating device.

[0032] Referring to Figures 1 to 5The utility model provides a raw material grinding granulating device, including frame 1, frame 1 is equipped with continuous crushing assembly 11, and the outlet of continuous crushing assembly 11 is equipped with mixing pipeline 2, and the inside of mixing pipeline 2 is equipped with liquid nozzle 22 for spraying adhesive, and the outlet of mixing pipeline 2 is equipped with temporary storage box 3, and the end of temporary storage box 3 away from mixing pipeline 2 is equipped with punch assembly 4, and temporary storage box 3 is equipped with feeding scraper 31, and the side of punch assembly 4 away from temporary storage box 3 is equipped with drying assembly 5, and punch assembly 4 is equipped with material return scraper 32 for pushing the completed punch to drying assembly 5, and the end of drying assembly 5 is equipped with finished product box 6. The operator puts raw materials into the continuous crusher, and the crushed materials fall into the mixing pipeline 2, and the liquid nozzle 22 sprays adhesive into the crushed raw materials, and the mixed raw materials are temporarily stored in the temporary storage box 3, and the wet powder in the temporary storage box 3 is scraped into the punch assembly 4 by the feeding scraper 31, and after the punch assembly 4 completes the punch, the completed granules are scraped into the drying assembly 5 by the material return scraper 32, and finally sent to the finished product box 6 after drying, so that the operator does not need to transport the intermediate products of raw materials, and the operator only needs to feed the continuous crusher to complete the entire operation process, which simplifies the operation complexity of the operator and improves the integration level of the device.

[0033] The continuous crushing assembly 11 is a continuous crusher. Since the continuous crusher is a common technical means in the industry and a commonly used component in the technical field, it will not be described here.

[0034] The punch assembly 4 includes a guide wheel 46, an upper punch 421, a lower punch 45, a pressing plate 42, an upper base plate 41, and a lower base plate 44. The upper punch 421 corresponds to the lower punch 45 one by one. The upper base plate 41 is provided with a plurality of upper punch holes for passing through the upper punch 421. The frame 1 is provided with a first air cylinder 43 for controlling the up-and-down movement of the pressing plate 42. The lower base plate 44 is provided with a plurality of lower punch holes for passing through the lower punch 45. The upper side of the upper punch 421 is fixedly connected with the pressing plate 42. The guide wheel 46 is circumferentially provided with a guide groove 461. The lower punch 45 is provided with a head, a neck, and a shaft body in sequence along the length. The head is located in the guide groove 461 and is slidably connected with the inside of the guide groove 461. The frame 1 is provided with a driving motor 47 for driving the guide wheel 46 to rotate. When the guide wheel 46 rotates, the lower punch 45 slides up and down along the inner wall of the upper and lower punch holes. When the raw materials are scraped to the lower base plate 44 by the feeding scraper 31, the first air cylinder 43 pushes the pressing plate 42 downward. The upper punch 421 moves downward guided by the upper punch holes. At this time, the upper punch 421 is in the lower punch hole to complete the pre-pressing. The driving motor 47 drives the guide wheel 46 to rotate. With the rotation of the guide wheel 46, the lower punch 45 moves upward in sequence. The extrusion of the upper punch 421 and the lower punch 45 completes the granulation process. The stress during the punch is effectively reduced by the sequential punch. The frame 1 is effectively prevented from shaking or the device from being damaged due to excessive pressure during the simultaneous punch of the punch assembly 4. The service life of the punch assembly 4 is effectively increased.

[0035] During the entire process, the lower punch 45 is always in the lower punch hole, and the raw materials are pressed and granulated together by the upper punch 421 , the lower punch 45 and the inner wall of the lower punch hole.

[0036] In order to better mix the powder and adhesive and ensure that the mixed materials are uniform and stable, the inner diameter of the mixing pipe 2 on the side closest to the temporary storage box 3 is larger than that on the other side. An air nozzle 21 is installed in the mixing pipe 2, facing the temporary storage box 3, and the liquid nozzle 22 is facing the opposite direction of the air nozzle 21. The air nozzle 21 can effectively help transport the powdered raw materials to the rear after crushing. By arranging the liquid nozzle 22 opposite the air nozzle 21, the mixing efficiency of the adhesive and powder can be maximized. By increasing the contact area, the mixing efficiency is improved.

[0037] In order to realize the feeding and unloading of the lower substrate 44 and ensure the stability during the loading process, the frame 1 is provided with a slide rail, and the loading scraper 31 and the unloading scraper 32 are both slidably connected to the slide rail. The frame 1 is provided with a second cylinder 33 for pushing the loading scraper 31 and the unloading scraper to slide along the slide rail. The unloading scraper 32 has a motion range from one end to the other end of the lower substrate 44. The motion range of the loading scraper 31 covers part of the temporary storage box 3 and all the lower punch holes. When the unloading scraper 32 pushes the stamped raw material out of the lower substrate 44 during the loading process, the loading scraper 31 pushes the material in the temporary storage box 3 onto the lower substrate 44, and the powder falls onto the lower punch 45 in the lower punch hole. When the loading scraper 31 and the unloading scraper 32 are reset, the unloading scraper 32 scrapes the excess powder back to the temporary storage box 3, effectively realizing the loading and unloading of the stamping assembly 4.

[0038] A slope is provided between the drying assembly 5 and the stamping assembly 4, with the drying assembly 5 located on the lower side of the slope. The drying assembly 5 includes a drying duct 54, a heating grille 51, and a blower 52. The blower 52 is located below the heating grille 51, and a discharge port is located above the drying duct 54. When the return scraper 32 pushes the stamped material to the blower 52, the blower 52 blows air toward the heating grille 51. The heated air blows the stamped material upward, drying the material as it moves upward.

[0039] Since the blower 52 remains on, a negative pressure is formed at the connection between the stamping assembly 4 and the drying assembly 5. The negative pressure draws the stamped particles into the drying duct 54, completing the feeding process of the drying assembly 5. The corners of the drying duct 54 are preferably curved, and the rear half of the drying duct 54 is designed to be inclined upward, which can effectively reduce the problem of particle accumulation and blockage in the drying duct 54.

[0040] The inclined baffle plates 53 are fixedly connected to the inside of the drying air duct 54, and a material passing space is left between the inclined baffle plates 53 for facilitating the passing of the particles. When the raw material after granulation moves upward in the drying air duct 54, the inclined baffle plates 53 concentrate the raw material, the speed of the raw material at the concentrated place is reduced, the air speed at this place is larger, and the drying efficiency is effectively improved.

[0041] Since the air blower 52 is always blowing air into the drying air duct 54 and the finished product box 6, if the air outlet is not arranged, the pressure in the finished product box 6 will be large, so that the finished raw material is difficult to enter the finished product box 6. The finished product box 6 is detachably connected to the end of the drying air duct 54 away from the stamping assembly 4, the upper side of the finished product box 6 is provided with an air vent, and the air vent is provided with a filter screen 61, the aperture of the filter screen 61 is smaller than the finished product particles. After the material in the finished product box 6 is accumulated, the operator takes down the finished product box 6, replaces the empty finished product box 6, and the filter screen 61 of the finished product box 6 can effectively facilitate the exhaust of the air blown in the drying air duct 54.

[0042] The above are the preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
