Description

Technical Field

[0001] The utility model belongs to the technical field of film coating production, and in particular relates to a film coating premixed auxiliary material grinding and mixing machine. Background Art

[0002] Film coating agents are generally composed of four parts: film-forming agents, plasticizers, solid additives and auxiliary agents. During production, these materials are pre-mixed according to a certain formula, proportion and specific production process to form a complete production material. In order to make the multiple raw materials evenly mixed together, they need to be ground into powder first and then mixed.

[0003] When grinding materials, the materials tend to adhere to the grinding roller, which can easily affect the overall grinding effect of the grinding roller. At the same time, the raw materials adhering to the grinding roller can easily change the ratio between the various raw materials, thereby making the overall effect of the film coating agent after it is produced prone to deviation.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In view of the problems in the related art, the utility model proposes a film coating premixed auxiliary material grinding and mixing machine to overcome the above technical problems existing in the existing related art.

[0007] The utility model is a film coating premixed auxiliary material grinding and kneading machine, comprising a grinding box, a grinding assembly is arranged inside the grinding box, a scraping assembly is arranged inside the grinding box, an intermittent pushing assembly is arranged at the grinding end of the grinding assembly, a mixing drum is fixedly installed at the bottom of the grinding box, and a stirring assembly is arranged inside the mixing drum.

[0008] The grinding assembly is used to grind materials, the scraping assembly is used to scrape materials on the grinding end of the grinding assembly, and the intermittent pushing assembly is used to push the scraping end of the scraping assembly to make the materials on the scraping end of the scraping assembly fall down.

[0009] Furthermore, the grinding assembly includes a grinding roller, the shaft head of the grinding roller is rotatably connected to the grinding box, two grinding rollers are symmetrically arranged, the shaft head of the grinding roller is fixedly connected to a connecting gear, the connecting gears on the two grinding rollers are meshed together, and a grinding motor is fixedly installed on the outer surface of the grinding box, and the output end of the grinding motor is fixedly connected to the shaft head at the other end of the grinding roller.

[0010] Furthermore, the scraping assembly includes a rotating shaft, which is rotatably connected to the grinding box. A scraper is fixedly connected to the outer surface of the rotating shaft, and the scraper is in contact with the outer surface of the grinding roller.

[0011] Furthermore, the scraping assembly also includes a mounting cylinder, which is fixedly mounted on the outer surface of the grinding box. The rotating shaft is rotatably connected to the mounting cylinder, and a torsion spring is fixedly connected between the outer surface of the rotating shaft and the inner wall of the mounting cylinder.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model is provided with a scraping assembly, so that when the grinding end of the grinding assembly is grinding the material, as the grinding end of the grinding assembly continuously rotates, the scraping end of the scraping assembly can scrape off the material adhering to the grinding end of the grinding assembly. The above arrangement makes it difficult for the grinding end of the grinding assembly to adhere to the material, thereby ensuring the overall grinding effect of the grinding assembly. At the same time, when the grinding assembly is grinding the material, the ratio between the various materials is not easy to change, thereby ensuring the overall quality of the film coating agent.

[0017] 2. The utility model provides a pushing block so that the scraper can be pushed by the pushing block when the grinding roller rotates.

[0029] The following will clearly and completely describe the technical solutions in the utility model embodiments in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the utility model embodiments, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of utility model protection.

[0030] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.

[0031] See also Figure 1-Figure 7 As shown, the utility model is a film coating premixed auxiliary material grinding and kneading machine, comprising a grinding box 1, a grinding component 2 is provided inside the grinding box 1, a scraping component 3 is provided inside the grinding box 1, an intermittent pushing component 4 is provided at the grinding end of the grinding component 2, a mixing drum 5 is fixedly installed at the bottom of the grinding box 1, and a stirring component 6 is provided inside the mixing drum 5.

[0032] The grinding component 2 is used to grind the material, the scraping component 3 is used to scrape the material on the grinding end of the grinding component 2, and the intermittent pushing component 4 is used to push the scraping end of the scraping component 3 to make the material on the scraping end of the scraping component 3 fall down.

[0033] By directly putting the material into the grinding box 1, the grinding component 2 starts to grind the material inside the grinding box 1, and the ground material passes directly through the grinding component 2 and falls directly into the mixing barrel 5. At the same time, the scraping component 3 can scrape the material adhering to the grinding end of the grinding component 2, and as the grinding end of the grinding component 2 rotates, the intermittent pushing component 4 can push the scraping end of the scraping component 3, so that the material on the scraping end of the scraping component 3 falls directly.

[0034] By providing the scraping component 3, when the grinding end of the grinding component 2 is grinding the material, as the grinding end of the grinding component 2 is continuously rotated, the scraping end of the scraping component 3 can scrape off the material adhering to the grinding end of the grinding component 2. The above-mentioned arrangement makes it less likely for the grinding end of the grinding component 2 to adhere to the material, thereby ensuring the overall grinding effect of the grinding component 2. At the same time, when the grinding component 2 is grinding the material, the ratio between the various materials is not likely to change, thereby ensuring the overall quality of the film coating agent.

[0035] In one embodiment, for the above-mentioned grinding component 2 package, the grinding component 2 includes a grinding roller 201, the shaft head of the grinding roller 201 is rotatably connected to the grinding box 1, and two grinding rollers 201 are symmetrically arranged. The shaft head of the grinding roller 201 is fixedly connected to a connecting gear 202, and the connecting gears 202 on the two grinding rollers 201 are meshed together. A grinding motor 203 is fixedly installed on the outer surface of the grinding box 1, and the output end of the grinding motor 203 is fixedly connected to the shaft head at the other end of the grinding roller 201.

[0036] By driving the grinding motor 203, the grinding motor 203 drives one of the grinding rollers 201 to rotate, and the rotating grinding roller 201 drives the other grinding roller 201 to rotate through two meshing connecting gears 202, so that the two grinding rollers 201 can grind the material put into the grinding box 1. When the material becomes powder, it can be directly passed between the two grinding rollers 201 and fall into the inside of the mixing drum 5 under the influence of its own gravity.

[0037] In one embodiment, the scraping assembly 3 includes a rotating shaft 301 , which is rotatably connected to the grinding box 1 , and a scraper 302 is fixedly connected to the outer surface of the rotating shaft 301 , which is in contact with the outer surface of the grinding roller 201 .

[0038] The scraper 302 can contact the outer surface of the grinding roller 201 under the support of the rotating shaft 301, and the scraper 302 is set at the bottom of the grinding roller 201, so that when the grinding roller 201 rotates and grinds the material, the scraper 302 can scrape off the material adhering to the grinding roller 201, so that the outer surface of the grinding roller 201 is not prone to material adhesion when grinding the material.

[0039] In one embodiment, for the above-mentioned scraping assembly 3, the scraping assembly 3 also includes a mounting cylinder 303, which is fixedly installed on the outer surface of the grinding box 1, and the rotating shaft 301 is rotatably connected to the mounting cylinder 303, and a torsion spring 304 is fixedly connected between the outer surface of the rotating shaft 301 and the inner wall of the mounting cylinder 303.

[0040] The torsion spring 304 twists the rotating shaft 301, so that the rotating shaft 301 drives the scraper 302 to contact the grinding roller 201. The setting of the torsion spring 304 makes the scraper 302 contact the outer surface of the grinding roller 201 more closely, so that the effect of the scraper 302 in scraping the material on the grinding roller 201 can be guaranteed.

[0041] In one embodiment, for the above-mentioned intermittent pushing component 4, the intermittent pushing component 4 includes a pushing block 401, and a plurality of the pushing blocks 401 are arranged on the circumference of the outer surface of the grinding roller 201. The inner wall of the grinding box 1 is provided with a receiving groove 402, and the pushing block 401 is located inside the receiving groove 402.

[0042] The two grinding rollers 201 are each provided with a pushing block 401, and the pushing blocks 401 are respectively provided at the opposite ends of the two grinding rollers 201, and the two ends of the two grinding rollers 201 are staggered. This arrangement enables the pushing block 401 to push the scraper 302 normally, and at the same time, the pushing block 401 will not make the gap between the two grinding rollers 201 larger, and the arrangement of the receiving groove 402 prevents the material from falling directly from one end of the two grinding rollers 201; at the same time, two scrapers 302 are provided at the bottom of each grinding roller 201. When the grinding roller 201 rotates, the pushing block 401 pushes the first scraper 302 Push, at this time the second scraper 302 continues to contact with the outer surface of the grinding roller 201, when the pushing block 401 moves out from the first scraper 302, the first scraper 302 can be reset under the action of the corresponding torsion spring 304, and at the same time the scraper 302 can generate a certain vibration force, so that it is not easy for material to accumulate on the scraper 302, then the pushing block 401 starts to push the second scraper 302, and makes the second scraper 302 repeat the moving process of the first scraper 302, the setting of the two scrapers 302 ensures that there will be no missed scraping when the scraper 302 rotates.

[0043] In one embodiment, for the above-mentioned stirring assembly 6, the stirring assembly 6 includes a rotating groove 601, which is opened on the inner wall of the mixing drum 5, and the internal rotation of the rotating groove 601 is connected to a driven gear 602, and the inner wall of the driven gear 602 is fixedly connected to a stirring frame 603, and the outer surface of the mixing drum 5 is fixedly installed with a stirring motor 604, and the output end of the stirring motor 604 is fixedly connected to a driving gear 605, and the inner wall of the rotating groove 601 is provided with a connecting groove 606, and the driving gear 605 is meshed with the driven gear 602 through the connecting groove 606.

[0044] The ground material falls directly into the mixing drum 5 under the influence of its own gravity. At this time, the stirring motor 604 drives the driving gear 605 to rotate, so that the driving gear 605 drives the driven gear 602 to rotate inside the rotating groove 601. At this time, the stirring frame 603 can stir the powdered material inside the mixing drum 5 under the drive of the driven gear 602, so that the materials can be evenly mixed together. The setting of the rotating groove 601 and the driven gear 602 allows the stirring motor 604 to drive it on one side of the driven gear 602 through the driving gear 605, so that the top of the mixing drum 5 is blocked. This setting makes it less likely that the material will be obstructed when falling into the mixing drum 5.

[0045] In one embodiment, for the stirring assembly 6 , the outer surface of the mixing drum 5 is fixedly connected to a support frame 7 , the bottom of the mixing drum 5 is fixedly connected to a discharge pipe 8 , and an electromagnetic valve 9 is provided inside the discharge pipe 8 .

[0046] By controlling the electromagnetic valve 9, the material mixed inside the mixing barrel 5 can fall directly from the discharge pipe 8. At the same time, the setting of the support frame 7 makes the bottom of the discharge pipe 8 have a certain distance from the ground, which makes it more convenient to carry out the material collection operation.

[0047] According to the above technical solution, 1. By setting the scraping component 3, when the grinding end of the grinding component 2 is grinding the material, as the grinding end of the grinding component 2 is continuously rotating, the scraping end of the scraping component 3 can scrape off the material adhering to the grinding end of the grinding component 2. The above setting makes it difficult for the grinding end of the grinding component 2 to adhere to the material, thereby ensuring the overall grinding effect of the grinding component 2. At the same time, when the grinding component 2 is grinding the material, the ratio between the various logistics is not easy to change, thereby ensuring the overall quality of the film coating agent; 2. By setting the pushing block 401, When the grinding roller 201 rotates, the scraper 302 can be pushed by the pushing block 401. When the pushing block 401 is not in contact with the scraper 302, the scraper 302 can be reset and contacted with the surface of the grinding roller 201 under the elastic force of the torsion spring 304. During this process, the scraper can generate a certain vibration, so that there will be no accumulation of materials on the scraper 302. At the same time, two scrapers are set at the bottom of the grinding roller 201, and the two scrapers 302 rotate successively under the push of the pushing block 401. This arrangement ensures that the scraper 302 will not miss any scraping when cleaning the accumulated materials.
