Description

Technical Field

[0001] The present invention belongs to the technical field of grinding devices, and particularly relates to a low-temperature ultrafine grinding device for flour products and a using method thereof. Background Art

[0002] Flour products are generally composed of flour or a mixture of other food flour products, and common ones include high-gluten flour, medium-gluten flour, and low-gluten flour. During the production process of flour products, in order to retain their nutritional components, improve the quality of flour, and meet special requirements, it is necessary to use a low-temperature ultrafine grinding device to grind them.

[0003] The existing low-temperature ultrafine grinding device includes a rotating module. The end of the output shaft of the rotating module is fixedly connected with a rotating shaft rod, and the rotating shaft rod penetrates through the blanking pipe fitting. A spiral blanking paddle and a grinding part are fixedly sleeved on the outer side of the rotating shaft rod. The rotating module drives the grinding part to grind the flour product through the rotating shaft rod.

[0004] The existing flour grinding device has certain limitations in the actual production process. The grinding parts inside it only grind the flour product by rotating, resulting in the phenomenon that the flour product is prone to local accumulation or surplus, reducing the grinding efficiency; at the same time, the flour will adhere to the inner wall of the grinding cavity during the grinding process, which will not only affect the overall grinding quality of the device but also reduce the output of the flour product.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a low-temperature ultrafine grinding device for flour products and a using method thereof to overcome the deficiencies in current practical applications. Summary of the Invention

The grinding shaft is arranged in parallel inside the grinding cylinder. The two ends of the grinding shaft are respectively rotatably connected to the sliders on two adjustment disks. Grinding rollers are fixed on the grinding shaft. Grinding parts are equidistantly distributed on the outer wall of the grinding roller. One side of the grinding part is matched with grinding grooves equidistantly distributed on the inner wall of the grinding cylinder. A notch is arranged on the other side of the grinding part. The mounting post is vertically slidably arranged in the notch. One end of the mounting post extends into a mounting hole opened on the grinding roller. One end of the mounting post is connected to the spring installed in the mounting hole. The other end of the mounting post extends to the outside of the grinding part and is fixedly connected to the scraping plate.

[0010] As a further technical solution of the present invention, the support component includes a hydraulic component, a connecting frame, a bottom bracket and a top bracket. The hydraulic components are symmetrically arranged inside the production chamber. The output end of the hydraulic component is rotatably connected to the connecting frame fixed at the bottom of the bottom bracket. A top bracket is installed above the bottom bracket. The installation cylinder is located between the bottom bracket and the top bracket and is rotatably connected to both of them.

[0011] As a further technical solution of the present invention, the rotating component includes a second motor, a main shaft and a linkage unit. The second motor is fixed inside the control box.

And a square channel communicating with each other is arranged on one side of the grinding cylinder. A storage cylinder is installed on one side of the square channel.

[0014] A usage method of the low-temperature ultrafine grinding device for the flour product as described above is as follows: First, the first motor drives the screw to rotate. The screw drives the slider to slide in the adjustment groove by rotating and being screwed with the side bracket. The slider drives the grinding assembly to move radially and changes the axial position of the grinding assembly. In the initial state, the axis of the grinding member is eccentric to the axis of the grinding cylinder. The scraper does not contact the inner wall of the grinding cylinder. The telescopic lengths of the two hydraulic members are the same. The top brackets, bottom brackets and the installation cylinder on the two hydraulic members are all in a horizontal state. The second motor drives the main shaft to rotate. The main shaft drives the first linkage disk and the universal joint thereon to rotate. The universal joint on the first linkage disk drives the second linkage disk to rotate through the fixed sleeve and the sliding column. The second linkage disk drives the rotating shaft to rotate. The rotating disk drives the adjustment disk to rotate. The adjustment disk drives the grinding shaft and the grinding roller to eccentrically rotate in the grinding cylinder through the slider. The grinding roller drives a plurality of grinding members and the scraper to eccentrically rotate. The eccentrically rotating grinding members cooperate with the grinding cylinder to achieve ultrafine grinding of the flour product. Second, due to the eccentric rotation of the grinding members, when the slider drives the grinding shaft and the grinding roller to move radially, the grinding roller drives a plurality of grinding members and the scraper to move radially and changes the eccentric distance between the grinding members and the grinding cylinder. The grinding members allow flour products of different specifications to enter the grinding area between the two by changing the eccentric distance from the grinding cylinder. The scraper moves to a position where it contacts the inner wall of the grinding cylinder and scrapes off the flour product adhered to the inner wall of the grinding cylinder. During the process of the grinding assembly grinding the flour product, the two hydraulic members reciprocally change the horizontal height of the two installation cylinders by reciprocally changing the telescopic length. The two installation cylinders drive the grinding cylinder and the grinding assembly to reciprocally tilt. The grinding cylinder and the grinding assembly drive the flour product to axially reciprocally move in the grinding cylinder by reciprocally tilting. 3. When the flour products in the grinding cylinder need to be discharged, the control unit drives the scraper to move to a position that conflicts with the inner wall of the grinding groove by rotating. The scraper cooperates with the rotating component to discharge the flour products hidden in the grinding groove. The supporting component reciprocates again to change the telescopic length of the two hydraulic parts and drives the grinding parts and the grinding cylinder to tilt reciprocally. The scraper in the rotating state cooperates with the supporting component to complete the efficient discharge of the flour products.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The rotating assembly drives the grinding assembly to rotate in the grinding cylinder through the control assembly. The control assembly can change the axial distance between the grinding assembly and the grinding cylinder, which not only facilitates flour products of different specifications to enter the grinding area between the grinding element and the grinding cylinder better, ensuring that the flour products in the grinding cylinder can be better and faster ground, reducing the grinding time, and improving the grinding efficiency and grinding quality of the device, but also facilitates the scraper to move to a position that conflicts with the inner wall of the grinding cylinder, so that the scraper can scrape off the flour products adhered to the inner wall of the grinding cylinder, so that they can fall into the grinding area, thereby facilitating the cooperation between the grinding element and the grinding cylinder to complete the ultrafine grinding of the flour products, avoiding excessive adhesion of the flour products and affecting the grinding efficiency and grinding quality of the device, and greatly improving the adaptability and flexibility of the device; At the same time, in cooperation with the support assembly, the support assembly can reciprocately change the horizontal height of the two mounting cylinders, so that the grinding cylinder and the grinding assembly can tilt reciprocatingly, which is convenient for the flour product to move axially reciprocatingly in the grinding cylinder, and convenient for the rotating grinding assembly to quickly and efficiently perform ultra-fine grinding on the flour product, thereby reducing the grinding time of the flour product.

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] The following describes the specific implementation of the present invention in detail with specific embodiments.

[0030] As shown in Figures 1 to 9As shown in the figure, a low-temperature ultrafine grinding device for a flour product provided as an embodiment of the present invention includes a device box 100. A production chamber 110 is provided on the device box 100. Inside the production chamber 110, a collection tray 130, a support assembly 200, a grinding cylinder 300, an installation cylinder 400, and a low-temperature refrigeration device 700 are sequentially installed. The output end of the low-temperature refrigeration device 700 is arranged on the grinding cylinder 300 and controls the low-temperature environment inside the grinding cylinder 300, so that the low-temperature environment inside the grinding cylinder 300 meets the low-temperature grinding environment of the flour product, ensuring the grinding quality of the flour product. The grinding cylinder 300 is horizontally arranged in the production chamber 110. Both ends of the grinding cylinder 300 are fixed with installation cylinders 400. The installation cylinders 400 are connected to the support assembly 200. The collection tray 130 is located directly below the grinding cylinder 300. A control box 120 is installed on one side of the device box 100. A rotation assembly 600 is arranged inside the control box 120. One end of the rotation assembly 600 extends into the production chamber 110. It further includes: A control assembly 500, which includes a rotating disk 510, a bearing 520, a rotating shaft 530, an adjustment disk 540, and a control unit 550. The rotating disk 510 is located inside the installation cylinder 400. A rotating shaft 530 is fixed on one side of the rotating disk 510. The rotating shaft 530 is rotationally connected to the inner wall of the installation cylinder 400 through the bearing 520. An adjustment disk 540 is fixed on the other side of the rotating disk 510. The control unit 550 is installed on the adjustment disk 540. The rotating shaft 530 inside the installation cylinder 400 near the rotation assembly 600 is connected to the rotation assembly 600. A grinding assembly 800, which is horizontally arranged inside the grinding cylinder 300. Both ends of the grinding assembly 800 are respectively rotatably installed on two control units 550. Grinding members 830 and scraping plates 860 are equidistantly distributed on the grinding assembly 800. The scraping plates 860 are located outside the grinding members 830.

[0031] In the initial state, the axis of the grinding member 830 is eccentric to the axis of the grinding cylinder 300, and the scraping plate 860 does not contact the inner wall of the grinding cylinder 300. The rotation assembly 600 drives the rotating disk 510 to rotate through the rotating shaft 530. The rotating disk 510 drives the adjustment disk 540 to rotate. The adjustment disk 540 drives the grinding assembly 800 to eccentrically rotate inside the grinding cylinder 300. The grinding assembly 800 drives the grinding members 830 to eccentrically rotate. The eccentrically rotating grinding members 830 can continuously exert extrusion and grinding forces on the flour product inside the grinding cylinder 300, gradually crushing and refining the flour particles, realizing the ultrafine grinding of the flour product, and gradually grinding its particle size to meet the required specifications. Due to the eccentric rotation of the grinding element 830, the grinding area between it and the grinding cylinder 300 is relatively limited. The control unit 550 can drive the grinding element 830 and the scraper 860 to move radially in the grinding cylinder 300 by rotating, thereby changing the eccentric distance between the grinding element 830 and the grinding cylinder 300. This not only facilitates flour products of different specifications to better enter the grinding area between the grinding element 830 and the grinding cylinder 300, but also ensures that the flour products in the grinding cylinder 300 can be better and faster. The grinding is achieved, the grinding time is reduced, the grinding efficiency and the grinding quality of the device are improved, and the scraper 860 is convenient to move to the position that conflicts with the inner wall of the grinding cylinder 300, so that the scraper 860 can scrape off the flour products adhered to the inner wall of the grinding cylinder 300 so that they can fall into the grinding area, thereby facilitating the cooperation between the grinding element 830 and the grinding cylinder 300 to complete the ultrafine grinding of the flour products, avoiding excessive adhesion of flour products and affecting the grinding efficiency and grinding quality of the device, and greatly improving the adaptability and flexibility of the device.

[0032] In a preferred embodiment, the rotating disk 510, the rotating shaft 530, the mounting cylinder 400, the grinding cylinder 300 and the adjusting disk 540 are all concentric; One side of the grinding cylinder 300 is provided with a square channel 310 that is interconnected, and one side of the square channel 310 is installed with a storage barrel 320. When the grinding cylinder 300 is discharging, the square channel 310 is separated from the storage barrel 320 and rotated to the top of the collecting plate 130, so that the flour products in the grinding cylinder 300 can fall onto the collecting plate 130 through the square channel 310, and the collection of the flour products is completed; the storage barrel 320 can be filled with flour products required for grinding in the next stage in advance. When the square channel 310 completes the discharge of the flour products in the previous stage, the grinding cylinder 300 is rotated again so that the discharge port of the square channel 310 faces upward. At this time, the storage barrel 320 is fixed on the square channel 310, so that the flour products in the storage barrel 320 can fall into the grinding cylinder 300 through the square channel 310, which is convenient for the grinding assembly 800 to perform ultra-fine grinding on them.

[0033] like Figures 2 to 5 As shown, as a preferred embodiment of the present invention, the control unit 550 includes a slider 551, a side bracket 552, a screw 553, a mounting plate 554 and a motor 555. The slider 551 is slidably installed in an adjustment slot 541 provided on the adjustment disk 540. The slider 551 is rotatably connected to the grinding assembly 800. A side bracket 552 is vertically fixed to one side of the slider 551. The side bracket 552 is threadedly connected to a screw 553 installed on the mounting plate 554. The mounting plate 554 is fixed to one side of the adjustment disk 540. A motor 555 is fixed on the mounting plate 554. The output end of the motor 555 is connected to one end of the screw 553.

[0034] The first motor 555 drives the screw rod 553 to rotate. The screw rod 553 can drive the slider 551 to slide in the adjustment groove 541 by rotating and being screwed to the side bracket 552. The slider 551 can drive the milling assembly 800 to move radially, thereby changing the eccentric distance between the milling assembly 800 and the milling cylinder 300, so that the milling assembly 800 can quickly and efficiently ultrafinely mill the flour product in the milling cylinder 300, gradually milling its particle size to meet the required specifications, and improving the milling quality and efficiency of the device for the flour product.

[0035] In a preferred embodiment, the adjustment groove 541 is opened on the adjustment disk 540 along the radial direction of the adjustment disk 540. The way the slider 551 slides in the adjustment groove 541 can move the milling assembly 800 to a position concentric or eccentric with the adjustment disk 540, so as to meet the milling requirements of the flour product.

[0036] As Figures 2 to 9 shown, as a preferred embodiment of the present invention, the milling assembly 800 includes a milling shaft 810, a milling roller 820, a mounting column 850, and a spring 880. The milling shaft 810 is arranged in parallel in the milling cylinder 300. The two ends of the milling shaft 810 are respectively rotatably connected to the sliders 551 on the two adjustment disks 540. The milling roller 820 is fixed on the milling shaft 810. The milling members 830 are equidistantly distributed on the outer wall of the milling roller 820. One side of the milling member 830 cooperates with the milling grooves 330 equidistantly distributed on the inner wall of the milling cylinder 300. A notch 840 is provided on the other side of the milling member 830. The mounting column 850 is vertically slidably arranged in the notch 840. One end of the mounting column 850 extends into the mounting hole 870 opened on the milling roller 820. One end of the mounting column 850 is connected to the spring 880 installed in the mounting hole 870. The other end of the mounting column 850 extends to the outside of the milling member 830 and is fixedly connected to the scraping plate 860.

[0037] The adjustment disk 540 drives the milling shaft 810 and the milling roller 820 to eccentrically rotate in the milling cylinder 300 through the slider 551. The milling roller 820 drives a plurality of milling members 830 and the scraping plate 860 to eccentrically rotate. The eccentrically rotating milling members 830 can continuously apply extrusion and milling forces to the flour product in the milling cylinder 300, so that the flour particles are gradually crushed and refined, realizing the ultrafine milling of the flour product; When the slider 551 drives the grinding shaft 810 and the grinding roller 820 to move radially, the grinding roller 820 drives a plurality of grinding members 830 and the scraper 860 to move radially, thereby changing the eccentric distance between the grinding members 830 and the grinding cylinder 300. This not only facilitates different specifications of flour products to better enter the grinding area between the grinding members 830 and the grinding cylinder 300, ensures that the flour products in the grinding cylinder 300 can be ground better and faster, reduces the grinding time, improves the grinding efficiency and quality of the device, but also facilitates the scraper 860 to move to a position where it abuts against the inner wall of the grinding cylinder 300, so that the scraper 860 can scrape off the flour products adhering to the inner wall of the grinding cylinder 300, making them fall into the grinding area, and further facilitating the cooperation between the grinding members 830 and the grinding cylinder 300 to complete the ultrafine grinding of the flour products.

[0038] In a preferred embodiment, the grinding member 830 preferably adopts an annular block structure, and the scraper 860 preferably adopts an arc-shaped plate structure; In the initial state, the slider 551 is located on one side of the adjustment groove 541. At this time, the grinding shaft 810 is eccentric with the adjustment disk 540, so that one side of the grinding member 830 can penetrate into the grinding groove 330, thereby completing the ultrafine grinding of the flour products; when the slider 551 moves in the direction close to the axis of the adjustment disk 540, the slider 551 drives the grinding shaft 810 to move radially, thereby changing the axial position of the grinding shaft 810 and the adjustment disk 540. The grinding shaft 810 drives the grinding member 830 to move radially, thereby expanding the distance between it and the grinding groove 330, enabling the flour products to better enter the grinding area. At the same time, it facilitates the scraper 860 to move to a position where it abuts against the inner wall of the grinding cylinder 300 and scrape off the flour products adhering to the inner wall of the grinding cylinder 300, ensuring the grinding efficiency and quality of the device.

[0039] As Figures 1 to 3 shown, as a preferred embodiment of the present invention, the support assembly 200 includes a hydraulic member 210, a connecting frame 220, a bottom bracket 230, and a top bracket 240. The hydraulic members 210 are symmetrically arranged in the production chamber 110. The output end of the hydraulic member 210 is rotatably connected to the connecting frame 220 fixed to the bottom of the bottom bracket 230. A top bracket 240 is installed above the bottom bracket 230. The installation cylinder 400 is located between the bottom bracket 230 and the top bracket 240 and is rotatably connected to both.

[0040] In the initial state, the telescopic lengths of the two hydraulic members 210 are the same, so that the top brackets 240, the bottom brackets 230, and the installation cylinder 400 on the two hydraulic members 210 are all in a horizontal state. The grinding assembly 800 can perform ultrafine grinding on the flour products in the grinding cylinder 300 by means of eccentric rotation; When the grinding assembly 800 grinds the flour product, the telescopic lengths of the two hydraulic components 210 are reciprocated, so that the horizontal heights of the output ends of the two hydraulic components 210 are different, thereby reciprocating the horizontal heights of the two mounting cylinders 400, so that the grinding cylinder 300 and the grinding assembly 800 are continuously tilted, so that the flour product can be easily moved axially in the grinding cylinder 300, and the grinding assembly 800 in a rotating state can be easily and efficiently grind the flour product ultra-finely, thereby reducing the grinding time of the flour product; When the grinding assembly 800 completes the grinding of the flour product, the scraper 860 in the grinding assembly 800 moves to a position that contacts the inner wall of the grinding groove 330, so that the flour product hidden in the grinding groove 330 can be discharged. The support assembly 200 reciprocates to change the telescopic length of the two hydraulic parts 210, so that the grinding cylinder 300 and the grinding assembly 800 are tilted reciprocatingly again. The scraper 860 in the rotating state cooperates with the support assembly 200, so that the flour product in the grinding cylinder 300 can be quickly discharged from the square channel 310 on the grinding cylinder 300, thereby reducing the discharge time of the flour product and improving the working efficiency, flexibility and practicality of the device.

[0041] In a preferred embodiment, the hydraulic component 210 preferably adopts a hydraulic telescopic structure composed of a hydraulic cylinder and a hydraulic rod; The bottom bracket 230 and the top bracket 240 are connected as a whole by bolts.

[0042] like Figure 2 , Figure 3 and Figure 10 As shown, as a preferred embodiment of the present invention, the rotating assembly 600 includes a motor 2 610, a main shaft 620 and a linkage unit 630. The motor 2 610 is fixed in the control box 120. The main shaft 620 is fixed on the output end of the motor 2 610. One end of the main shaft 620 extends into the production chamber and is connected to a rotating shaft 530 in a mounting cylinder 400 through the linkage unit 630.

[0043] like Figure 2 , Figure 3 and Figure 10 As shown, as a preferred embodiment of the present invention, the linkage unit 630 includes a linkage disk 1 631, a universal joint 632, a fixed sleeve 633, a sliding column 634 and a linkage disk 2 635, the linkage disk 1 631 is concentrically fixed on the main shaft 620, a universal joint 632 is fixed on one side of the linkage disk 1 631, the linkage disk 2 635 is concentrically fixed on the rotating shaft 530, a universal joint 632 is fixed on one side of the linkage disk 2 635, a fixed sleeve 633 and a sliding column 634 are installed between the two universal joints 632, and the sliding column 634 and the fixed sleeve 633 are axially slidably connected.

[0044] In a preferred embodiment, the second motor 610 drives the main shaft 620 to rotate. The main shaft 620 drives the first linkage disk 631 and the universal joint 632 thereon to rotate. The universal joint 632 on the first linkage disk 631 can drive the second linkage disk 635 to rotate through the fixed sleeve 633 and the sliding column 634. The second linkage disk 635 drives the rotating shaft 530 to rotate, thereby driving the grinding assembly 800 to rotate eccentrically or concentrically within the grinding cylinder 300. This enables the grinding assembly 800 not only to perform ultrafine grinding on the flour product, but also to quickly scrape off the flour product adhering to the inner wall of the grinding cylinder 300, reducing the grinding time and discharging time of the device, and improving the working efficiency, flexibility, and practicality of the device. The sliding connection of the two universal joints 632 and the matching fixed sleeve 633 and sliding column 634 can ignore the inclination angle of the grinding cylinder 300 and the rotating shaft 530, enabling the second motor 610 to efficiently transfer the rotational speed to the rotating shaft 530 quickly and ensuring the working stability of the grinding assembly 800.

[0045] A method for using the low-temperature ultrafine grinding device for flour products as described above is as follows: First, the first motor 555 drives the screw 553 to rotate. The screw 553 can drive the slider 551 to slide within the adjustment groove 541 by rotating and being screwed to the side bracket 552. The slider 551 can drive the grinding assembly 800 to move radially, thereby changing the axial position of the grinding assembly 800. In the initial state, the axis of the grinding member 830 is in an eccentric state with the axis of the grinding cylinder 300, the scraping plate 860 does not contact the inner wall of the grinding cylinder 300, and the telescopic lengths of the two hydraulic members 210 are the same, so that the top support brackets 240, bottom support brackets 230, and mounting cylinder 400 on the two hydraulic members 210 are all in a horizontal state. The second motor 610 drives the main shaft 620 to rotate. The main shaft 620 drives the first linkage disk 631 and the universal joint 632 thereon to rotate. The universal joint 632 on the first linkage disk 631 can drive the second linkage disk 635 to rotate through the fixed sleeve 633 and the sliding column 634. The second linkage disk 635 drives the rotating shaft 530 to rotate. The rotating disk 510 drives the adjustment disk 540 to rotate. The adjustment disk 540 drives the grinding shaft 810 and the grinding roller 820 to rotate eccentrically within the grinding cylinder 300 through the slider 551. The grinding roller 820 drives the plurality of grinding members 830 and the scraping plate 860 to rotate eccentrically. The eccentrically rotating grinding members 830 can continuously exert extrusion and grinding forces on the flour product within the grinding cylinder 300, causing the flour particles to be gradually crushed and refined, realizing the ultrafine grinding of the flour product. Second, due to the eccentric rotation of the grinding member 830, the grinding area between it and the grinding cylinder 300 is relatively limited. When the slider 551 drives the grinding shaft 810 and the grinding roller 820 to move radially, the grinding roller 820 drives a plurality of grinding members 830 and the scraper 860 to move radially, thereby changing the eccentric distance between the grinding member 830 and the grinding cylinder 300. This not only facilitates flour products of different specifications to better enter the grinding area between the grinding member 830 and the grinding cylinder 300, ensures that the flour products in the grinding cylinder 300 can be ground better and faster, reduces the grinding time, improves the grinding efficiency and quality of the device, but also facilitates the scraper 860 to move to a position where it abuts against the inner wall of the grinding cylinder 300, enabling the scraper 860 to scrape off the flour products adhering to the inner wall of the grinding cylinder 300 so that they can fall into the grinding area; Reciprocally change the telescopic lengths of the two hydraulic members 210, so that the horizontal heights of the output ends of the two hydraulic members 210 are different, thereby reciprocally changing the horizontal heights of the two mounting cylinders 400, causing the grinding cylinder 300 and the grinding assembly 800 to tilt continuously. This facilitates the axial reciprocating movement of the flour products in the grinding cylinder 300 and enables the rotating grinding assembly 800 to quickly and efficiently perform ultrafine grinding on the flour products, reducing the grinding time of the flour products; Third, when it is necessary to discharge the flour products in the grinding cylinder 300, the control unit 550 can drive the scraper 860 to move to a position where it abuts against the inner wall of the grinding groove 330 by rotating. At the same time, in cooperation with the rotating assembly 600, it can discharge the flour products hidden in the grinding groove 330. The support assembly 200 reciprocally changes the telescopic lengths of the two hydraulic members 210 again, causing the grinding cylinder 300 and the grinding assembly 800 to tilt reciprocally again. In the way that the rotating scraper 860 cooperates with the support assembly 200, it facilitates the flour products in the grinding cylinder 300 to be quickly discharged from the square channel 310 on the grinding cylinder 300, thereby completing the efficient discharging of the flour products and reducing the discharging time of the flour products.

Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
