Description

Technical Field

[0001] The invention relates to the technical field of flour screening, in particular to a low-gluten flour screening machine with a double-layer screen peak-shifting vibration structure for producing navel orange pastries. Background Art

[0002] The low-gluten flour used for navel orange pastries usually requires finer particles. Fine flour can make the navel orange pastries softer and crispier. If the flour particles are too coarse, it may cause the dough to have a rough texture and be difficult to handle during the molding process. The navel orange pastries will also have a poor taste and a noticeable granular feel, affecting the overall eating experience. Therefore, the flour needs to be sifted first when mass-producing navel orange pastries.

[0003] In current production, it is generally necessary to screen flour through a vibrating screen to ensure the fineness of the flour. When screening flour, the existing vibrating screen usually drives the screen to vibrate rapidly centrifugally through a vibrating motor, and the flour particles move violently on the screen. Since the screen is flat, the flour particles will inevitably move rapidly to the edge of the screen under the continuous action of centrifugal vibration. Many flour particles accumulate and gather at the edge to form larger flour blocks. These flour blocks are not only difficult to pass through the screen, but also hinder the normal movement of subsequent flour particles to the edge, causing a large amount of flour to remain in the edge area of ​​the screen for a long time and unable to complete screening through the screen in time, ultimately resulting in a significant reduction in the overall screening efficiency, seriously affecting the production progress and capacity of flour processing. Summary of the invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a low-gluten flour screening machine with a double-layer screen peak-shifting vibration structure for the production of navel orange pastries, which can effectively solve the problem in the prior art that when using a vibrating screen, the vibrating motor drives the screen to produce centrifugal vibration, and the flour blocks that are not easy to pass through the screen will be accumulated on the edge of the screen due to the centrifugal force. These flour blocks are not only difficult to pass through the screen themselves, but also hinder the movement of subsequent flour particles, causing the flour to be retained at the edge for a long time, resulting in low screening efficiency and affecting production progress and capacity.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: The low-gluten flour sieving machine with double-layer screen peak-shifting vibration structure for navel orange pastry production includes: The screening part includes a base, a silo is fixedly connected to the base, two vibration motors are symmetrically fixedly connected to the outside of the silo through a connecting seat, two discharge channels are also symmetrically fixedly connected to the outer wall of the silo, the discharge channels and the vibration motors are staggered with each other, and a screening unit is connected to the inside of the silo.

[0006] The inclined part includes a central shaft, the screening unit is connected with the central shaft, the lower end of the central shaft is fixedly connected with a reduction motor through a coupling, and the upper end of the central shaft is connected with a deflection unit.

[0007] Among them, the deflection unit includes a transmission ring, which is fixedly mounted on the central axis through a connecting piece in an inclined posture relative to the central axis, so that when observed from directly above the central axis, the transmission ring appears to be circular, and a tilting component is connected to the transmission ring. The top of the central axis is connected to the screening unit through a connecting component. When the transmission ring rotates, the screening unit is driven to swing back and forth through the tilting component and the connecting component.

[0008] Furthermore, the screening unit includes a waist-shaped container, which is fixedly connected to the inner wall of the silo, a No. 1 filter is fixedly connected to the bottom of the waist-shaped container, a No. 2 filter is fixedly connected to the inner wall of the silo and below the No. 1 filter, an annular enclosure is fixedly connected to the upper end of the waist-shaped container, and a crushing assembly is commonly connected to the waist-shaped container and the silo.

[0009] Furthermore, the crushing assembly includes a folding rod, which adopts an open design and has two symmetrically fixed connections on the inner wall of the waist-shaped container. The two straight sections of the folding rod are commonly connected with a telescopic module, the telescopic module is connected with a crushing module, and the arc section of the folding rod and the silo are commonly connected with a knocking module.

[0010] Furthermore, the telescopic module includes a bidirectional movable spring rod, which is slidably connected between two straight sections of the folding rod. Two movable blocks are symmetrically slidably connected to the fixed section of the bidirectional movable spring rod, and a crushing module is commonly connected between the movable blocks.

[0011] Furthermore, the crushing module includes a mounting rod, which is slidably connected between the movable blocks. A plurality of mounting rings are evenly slidably connected to the mounting rod along its length direction. A guide rod is fixedly connected to the lower end of the mounting ring, and a spring is commonly connected between adjacent mounting rings.

[0012] Furthermore, the knocking module includes a guide rod, which has three evenly fixed connections on the fixed section of the bidirectional movable spring rod. The guide rod slides through the arc section of the folding rod, the waist-shaped container and the silo and extends to the outside of the silo. A knocking weight is provided on the sliding sleeve of the guide rod, and the knocking weight is located outside the silo.

[0013] Furthermore, the tilting assembly includes an annular track, which is opened on the circumferential outer surface of the transmission ring. Balls are symmetrically slidably connected in the annular track. A vertical rod is fixedly connected to the ball. A sliding seat is rotatably connected to the upper end of the vertical rod. The sliding seat is slidably connected to the No. 2 filter.

[0014] Furthermore, the connecting assembly includes a fixed seat, and the center positions of filter screen No. 1 and filter screen No. 2 are commonly fixedly connected with the fixed seat, the upper end of the central axis is connected to the fixed seat through a ball joint, and a limit frame is rotatably sleeved on the central axis, the limit frame and the vertical rod are slidably connected, and the lower end of the fixed seat and the limit frame are commonly fixedly connected with a corrugated seat.

[0015] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The reduction motor in the present invention drives the central shaft to rotate through the coupling, and the connecting piece drives the transmission ring to rotate synchronously. Since the transmission ring is inclined, it will rotate relative to the ball when it rotates, thereby driving the two vertical rods connected to it to move synchronously in the opposite direction through the two balls, and then driving the No. 1 filter, the No. 2 filter, the waist-shaped container and the silo to tilt reciprocatingly around the connection between the central shaft and the fixed seat through the fixed seat. During the reciprocating tilting process of the No. 1 filter, the flour blocks accumulated at the high part of the No. 1 filter due to the centrifugal vibration will slide to the low part of the No. 1 filter, so that the flour accumulated at the edge will be spread to the low part of the No. 1 filter, thereby increasing the contact area between the flour blocks and the No. 1 filter, enhancing the efficiency of vibration crushing, and thereby improving the screening efficiency.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] The present invention will be further described below in conjunction with the embodiments.

[0027] Example:

[0028] See also Figure 1-Figure 7 , the low-gluten flour sieving machine with double-layer screen peak-shifting vibration structure for navel orange crisp production includes: The screening part includes a base 1, to which a silo 2 is fixedly connected, and two vibration motors are symmetrically fixedly connected to the outside of the silo 2 through a connecting seat (in the prior art, when two vibration motors move synchronously, centrifugal vibration will be generated on the silo 2), and two discharge channels are symmetrically fixedly connected to the outer wall of the silo 2, and the discharge channels and the vibration motors are staggered with each other, and a screening unit 3 is connected inside the silo 2.

[0029] The inclined part includes a central shaft 4 , the screening unit 3 is connected with the central shaft 4 , the lower end of the central shaft 4 is fixedly connected with a reduction motor via a coupling, and the upper end of the central shaft 4 is connected with a deflection unit 5 .

[0030] Among them, the deflection unit 5 includes a transmission ring 51, which is fixedly mounted on the central shaft 4 through a connecting piece in a posture inclined to the axis, so that when observed from directly above the central shaft 4, the transmission ring 51 appears to be circular, and a tilting component 52 is connected to the transmission ring 51. The top of the central shaft 4 is connected to the screening unit 3 through a connecting component 53. When the transmission ring 51 rotates, it will drive the screening unit 3 to swing back and forth through the tilting component 52 and the connecting component 53.

[0031] During the specific implementation, the flour to be screened is poured into the screening unit 3, and the two vibration motors operate synchronously, driving the silo 2 and the screening unit 3 to vibrate synchronously, and the flour is vibrated and crushed. A part of the flour with smaller particle size directly passes through the screening unit 3 and falls into the bottom of the silo 2, and slides from the discharge channel to the external container below with the centrifugal vibration of the silo 2. The other part of the flour blocks that cannot pass through is blocked inside the screening unit 3. This part of the flour will accumulate at the edge of the screening unit 3 under the action of the centrifugal vibration of the silo 2 until it is vibrated and crushed into a particle size that can pass through the screening unit 3.

[0032] While the silo 2 is centrifugally vibrating, the reduction motor also works synchronously, driving the central shaft 4 to rotate at a relatively slow speed through the coupling (the coupling is an elastic coupling to prevent the vibration on the silo 2 and the screening unit 3 from being transmitted to the reduction motor and affecting the reduction motor), thereby driving the transmission ring 51 to rotate synchronously, and then driving the screening unit 3 and the silo 2 to tilt periodically through the tilting component 52 and the connecting component 53, promoting the flour blocks accumulated at the edge of the screening unit 3 to roll back to the center of the screening unit 3, so as to facilitate the screening unit 3 to vibrate and crush them.

[0033] The screening unit 3 includes a waist-shaped container 31, which is fixedly connected to the inner wall of the silo 2. A No. 1 filter screen 32 is fixedly connected to the bottom of the waist-shaped container 31. A No. 2 filter screen 33 is fixedly connected to the inner wall of the silo 2 and below the No. 1 filter screen 32. An annular enclosure plate 34 is fixedly connected to the upper end of the waist-shaped container 31. A crushing assembly 35 is commonly connected to the waist-shaped container 31 and the silo 2.

[0034] The crushing assembly 35 includes a folding rod 351, which adopts an open design and has two symmetrically fixed connections on the inner wall of the waist-shaped container 31. A telescopic module 352 is commonly connected to the two straight sections of the folding rod 351, and a crushing module 353 is connected to the telescopic module 352. A knocking module 354 is commonly connected to the arc section of the folding rod 351 and the silo 2.

[0035] The telescopic module 352 includes a bidirectional movable spring rod 3521, which is slidably connected between two straight sections of the folding rod 351. Two movable blocks 3522 are symmetrically slidably connected to the fixed section of the bidirectional movable spring rod 3521, and the crushing module 353 is commonly connected between the movable blocks 3522.

[0036] The crushing module 353 includes a mounting rod 3531, which is slidably connected between the movable blocks 3522. A plurality of mounting rings 3532 are evenly slidably connected to the mounting rod 3531 along its length direction. The lower end of the mounting ring 3532 is fixedly connected to the crushing rod 3533, and a spring is commonly connected between adjacent mounting rings 3532.

[0037] The knocking module 354 includes a guide rod 3541, and three guide rods 3541 are evenly fixedly connected on the fixed section of the bidirectional movable spring rod 3521. The guide rod 3541 slides through the arc section of the folding rod 351, the waist-shaped container 31 and the silo 2 and extends to the outside of the silo 2. A knocking weight 3542 is slidably sleeved on the guide rod 3541, and the knocking weight 3542 is located outside the silo 2.

[0038] The tilting assembly 52 includes an annular track 521, which is opened on the circumferential outer surface of the transmission ring 51. Ball bearings 522 are symmetrically slidably connected inside the annular track 521. A vertical rod 523 is fixedly connected to the ball bearings 522. The upper end of the vertical rod 523 is rotatably connected to a sliding seat, and the sliding seat is slidably connected to the No. 2 filter screen 33.

[0039] The connecting assembly 53 includes a fixed seat 531, and the center positions of the No. 1 filter 32 and the No. 2 filter 33 are fixedly connected with the fixed seat 531. The upper end of the central axis 4 is connected to the fixed seat 531 through a ball joint. A limit frame 532 is rotatably sleeved on the central axis 4. The limit frame 532 and the vertical rod 523 are slidably connected. The lower end of the fixed seat 531 and the limit frame 532 are fixedly connected with a corrugated seat 533. Under the action of the corrugated seat 533, when the central axis 4 rotates, the limit frame 532, the vertical rod 523 and the ball 522 are always in a stationary state.

[0040] During specific implementation, the reduction motor drives the central shaft 4 to rotate through the coupling, and when the central shaft 4 rotates, it drives the transmission ring 51 to rotate synchronously through the connecting piece. Since the transmission ring 51 is inclined, when the transmission ring 51 rotates, it will rotate relative to the ball 522, thereby driving the vertical rod 523 connected thereto to move upward or downward through the ball 522 (in this process, the slide seat will adaptively slide to compensate for the displacement caused by the deflection between it and the No. 2 filter screen 33), and then drive the No. 1 filter screen 32, the No. 2 filter screen 33, the waist-shaped container 31 and the silo 2 to tilt reciprocatingly around the connection between the central shaft 4 and the fixed seat 531 through the fixed seat 531.

[0041] When the No. 1 filter 32 is tilted, the flour blocks accumulated at its edge due to the centrifugal vibration, if located at a high place, will roll toward the center of the No. 1 filter 32 under the action of their own gravity. During this process, multiple flour blocks will be spread flat on the No. 1 filter 32, thereby increasing the contact area between the flour blocks and the No. 1 filter 32, thereby improving the vibration crushing efficiency and promoting the rapid crushing and falling of the flour blocks.

[0042] When the silo 2 and the waist-shaped container 31 are tilted, the guide rod 3541 and the knocking weight 3542 are driven to tilt synchronously. When the knocking weight 3542 located at the lower position is tilted, it moves in the direction away from the silo 2 under the action of its own gravity, thereby driving the two-way movable spring rod 3521 connected thereto to move in the direction close to the silo 2 through the guide rod 3541 located at the lower position. Since the folding rod 351 is designed to be open, the two ends of the two-way movable spring rod 3521 located at the lower position will automatically shrink during the movement, driving the two movable blocks 3542 on the fixed section thereof to move. 22 moves in the same direction, thereby driving the various mounting rings 3532 on the lower mounting rod 3531 to gradually approach each other, and the spring between the two adjacent mounting rings 3532 at the lower position is gradually compressed. In this process, the distance between the various crushing rods 3533 at the lower position is also gradually shortened, thereby crushing the larger flour blocks that cannot pass through the crushing rods 3533 on the way down. When the lower crushing rods 3533 continue to move toward the waist-shaped container 31, the flour blocks accumulated at the lower position will also be crushed, thereby further accelerating the crushing of the flour blocks.

[0043] When the silo 2 and the waist-shaped container 31 are tilted, the knocking weight 3542 located at a high position moves towards the silo 2 under the action of its own gravity, and finally knocks on the outer wall of the silo 2 to vibrate the silo 2. At the same time, the waist-shaped container 31, the filter screen No. 1 32 and the filter screen No. 2 33 also vibrate synchronously, promoting the flour to pass through the filter screen No. 1 32 and the filter screen No. 2 33, so as to avoid the flour clogging the filter screen No. 1 32 and the filter screen No. 2 33. At the same time, due to the difference in the distance between the knocking weights 3542 on different guide rods 3541 and the outer wall of the silo 2, there is a difference in the time for the knocking weights 3542 to reach the outer wall of the silo 2 and the knocking, so that multiple knocks can be completed in a single tilt, further improving the feeding efficiency.

[0044] It is worth mentioning that the low-gluten flour sieving machine with double-layer screen peak-shifting vibration structure for navel orange crisp production has the following advantages: Advantage 1. In this embodiment, the reduction motor drives the central shaft 4 to rotate through the coupling, so that the connecting member drives the transmission ring 51 to rotate synchronously. Since the transmission ring 51 is tilted, it will rotate relative to the ball 522 when it rotates, so that the two vertical rods 523 connected to it are driven to move synchronously in the opposite direction through the two balls 522, and then the No. 1 filter 32, the No. 2 filter 33, the waist-shaped container 31 and the silo 2 are driven to tilt reciprocally around the connection between the central shaft 4 and the fixed seat 531 through the fixed seat 531. In the process of reciprocating tilting, the No. 1 filter 32 will drive the flour blocks accumulated at the high part of the No. 1 filter 32 due to the centrifugal vibration to slide to the low part of the No. 1 filter 32, thereby changing the flour blocks from the stacked state to the flat state, thereby increasing the contact area between the flour blocks and the No. 1 filter 32, and enhancing the efficiency of vibration crushing.

[0045] Advantage 2. In this embodiment, when the silo 2 and the waist-shaped container 31 are tilted, the guide rod 3541 and the knocking weight 3542 will be driven to tilt synchronously. When the knocking weight 3542 located at the lower position is tilted, the lower guide rod 3541 and the two-way movable spring rod 3521 connected thereto will be driven to move in the direction close to the silo 2 under the action of its own gravity, thereby driving the two-way movable spring at the lower position to automatically contract, and driving the two movable blocks 3522 on its fixed section to move in the same direction, thereby driving the various mounting rings 3532 and the crushing rod 3533 on the lower mounting rod 3531 to gradually approach each other, crushing the larger flour blocks that cannot pass through the crushing rod 3533 on the way down, and in the process of the lower crushing rod 3533 continuing to move toward the waist-shaped container 31, the smaller flour blocks accumulated at the lower position and close to the hopper will also be crushed, thereby further accelerating the crushing of the flour blocks.

[0046] Advantage three: In the present embodiment, when the silo 2 and the waist-shaped container 31 are tilted, the knocking weight 3542 located at a high position moves along the guide rod 3541 towards the silo 2 under the action of its own gravity, and finally knocks on the outer wall of the silo 2 to make the silo 2 vibrate. At the same time, the waist-shaped container 31, the filter screen No. 1 32 and the filter screen No. 2 33 also vibrate synchronously, which, on the one hand, promotes the flour to pass through the filter screen No. 1 32 and the filter screen No. 2 33 to avoid the flour clogging the filter screen No. 1 32 and the filter screen No. 2 33, and on the other hand, promotes the flour blocks that roll freely to the low place and fit with the waist-shaped container 31 to be broken.

[0047] Advantage 4: In this embodiment, when the silo 2 is tilted, the discharge channel will also be tilted. The flour accumulated at the bottom of the silo 2 after screening will quickly slide down as the silo 2 tilts, and fall along the lower discharge channel to the external container below. Compared with the conventional centrifugal discharge method, the discharge efficiency is higher.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
