Description

Technical Field

[0001] The utility model relates to the technical field of food additive processing devices, in particular to a reinforcing device for a screen frame of a phosphate food additive pulverizer. Background Art

[0002] Phosphate is one of the natural ingredients of almost all foods. It is widely used in food processing as an important food ingredient and functional additive. It is a salt of phosphoric acid and is a very important substance in inorganic chemistry, biochemistry and biogeochemistry. Naturally occurring phosphate is phosphate rock (containing calcium phosphate). Phosphate can be obtained by reacting phosphate rock with sulfuric acid to produce calcium dihydrogen phosphate and calcium sulfate that can be absorbed by plants. Phosphate can be divided into orthophosphate and condensed phosphate: Phosphates used in food processing are usually sodium salts, calcium salts, potassium salts, and iron and zinc salts as nutritional enhancers. There are more than 30 varieties of commonly used food-grade phosphates. With the development of food processing technology, the consumption of potassium phosphate is also increasing year by year. Phosphates need to be crushed and then screened during processing, but the existing food additive crusher can only crush food additives simply. After crushing, the food additives need to be poured out to the next process for screening. At present, most of the screening work is done by manually swinging the screen, which is inefficient and labor-intensive.

[0003] In the prior art, a Chinese patent with a publication number of CN220328798U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a food additive crusher for food production, including a frame, a crushing chamber arranged on the frame, two crushing rollers are rotatably connected to the inner cavity of the crushing chamber, and also includes a swing frame arranged on the crushing chamber, a sieving frame is movably connected to the swing frame, the sieving frame is located directly below the two crushing rollers, and two toggle rods are rotatably connected at both ends of the inner wall of the crushing chamber; the toggle rods are driven to rotate, one of which can move in the direction of the swing frame, and the other toggle rod moves to the side away from the swing frame, so that the two ends of the sieving frame swing left and right inside the crushing chamber. After adopting the above technical solution, the food additive crusher for food production provided by the utility model can crush and screen food additives, and the screening efficiency is improved while the degree of automation is high.

[0004] Although the above-mentioned prior art can crush and screen food additives, and has a high degree of automation while improving screening efficiency, its screening frame is only connected to the limit rod through a through hole. During the screening process, the two ends of the screening frame need to swing left and right inside the crushing chamber. Over time, the screening frame is prone to falling off due to swinging and vibration. Utility Model Content

[0008] The inner wall of the receiving tube is threadedly connected with a fastening bolt, the outer wall of the fastening bolt is sleeved with an auxiliary spring, and a closing component for auxiliary reinforcement of the frame and the receiving plate is provided at the connection between the frame and the receiving plate.

[0026] Example 1

[0027] like Figure 1-6 As shown, the utility model provides a reinforcement device for a phosphate food additive grinder screen frame, including a grinder housing 1 and a screen frame 2, both sides of the screen frame 2 are fixedly connected with a frame 4, the bottom surface of the frame 4 is overlapped with a receiving plate 3, the upper surface of the receiving plate 3 is fixedly connected with a receiving tube 7, and the bottom surface of the frame 4 is provided with an adapter hole 8 for adapting to the receiving tube 7.

[0028] The inner wall of the receiving tube 7 is threadedly connected with a fastening bolt 6, and the outer wall of the fastening bolt 6 is sleeved with an auxiliary spring 9. A closing component for auxiliary reinforcement of the frame 4 and the receiving plate 3 is provided at the connection between the two.

[0029] The closing assembly includes a C-shaped closing frame 5, the upper surface of which is provided with an arc groove 12 adapted to the fastening bolt 6, and the bottom end of the auxiliary spring 9 overlaps the upper surface of the C-shaped closing frame 5. The fastening bolt 6 can be rotated and disassembled manually, and then the C-shaped closing frame 5 is pulled sideways to contact the blocking and reinforcement state of the frame 4 and the receiving plate 3, thereby facilitating the installation and disassembly of the screen frame 2.

[0030] The top of the auxiliary spring 9 is fixedly connected to the outer bottom surface of the fastening bolt 6. The connection stability between the connecting plate 3 and the frame 4 is improved by using the supporting plate 3, the frame 4, the supporting tube 7, the adapter hole 8 and the fastening bolt 6. At the same time, the auxiliary spring 9 and the C-type closed frame 5 are used in combination. With the help of the reaction force of the auxiliary spring 9 after being compressed, the C-type closed frame 5 can be more firmly clamped at the connection between the frame 4 and the connecting plate 3, and the deformation force of the auxiliary spring 9 can also be used to buffer the vibration of the screen frame 2, thereby preventing the screen frame 2 from falling off easily under the condition of swinging and vibration.

[0031] Example 2

[0032] like Figure 1-6As shown, based on Example 1, the utility model provides a technical solution: preferably, the bottom surface of the receiving plate 3 is fixedly connected with a slide rail 14, the inner wall of the slide rail 14 is slidably connected with a slider 10 fixedly connected to the bottom of the inner wall of the C-type closed frame 5, and an auxiliary groove 13 is opened at one end of the C-type closed frame 5.

[0033] The inner wall of the slide rail 14 is provided with a built-in groove 15 , the outer wall of the slide block 10 is movably connected with a side block 11 , and the outer wall of the side block 11 is slidably connected to the inner wall of the built-in groove 15 .

[0034] The outer wall of one end of the slide rail 14 is plugged into the inner wall of the auxiliary groove 13 , and the outer wall of the receiving tube 7 is plugged into the inner wall of the adapting hole 8 .

[0035] The working principle of the reinforcement device of the phosphate food additive pulverizer screen frame is described in detail below.

[0036] like Figure 1-6 As shown, the adapting hole 8 on the side frame 4 of the screen frame 2 is connected with the receiving tube 7 on the upper surface of the receiving plate 3, and then the frame 4 is moved down, and the receiving tube 7 is inserted into the adapting hole 8, and then the C-type closing frame 5 is pushed toward the screen frame 2. At this time, the slider 10 drives the side block 11 to slide on the inner wall of the slide rail 14, and the C-type closing frame 5 clamps the frame 4 and the receiving plate 3. After that, the bottom end of the fastening bolt 6 is connected with the receiving tube 7 and then begins to tighten. At this time, the bottom end of the auxiliary spring 9 is overlapped on the upper surface of the C-type closing frame 5, and the top end of the auxiliary spring 9 is located at the bottom of the outer edge of the fastening bolt 6. As the fastening bolt 6 is tightened, the auxiliary spring 9 is gradually compressed to generate a reaction force, which is applied to the C-type closing frame 5, so that the C-type closing frame 5 can strengthen the connection stability between the frame 4 and the receiving plate 3.

[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
