Description

Technical Field

[0001] The present invention relates to the technical field of flour screening, and particularly to a low-gluten flour sieve for the production of navel orange pastries with a double-layer screen staggered vibration structure. Background Art

[0002] The low-gluten flour used for navel orange pastries usually requires relatively fine particles. Fine flour can make the navel orange pastries taste softer and crisper. If the flour particles are too coarse, it may cause the dough texture to be rough, difficult to operate during the forming process, and the navel orange pastries made will also have a relatively poor taste, with obvious granularity, affecting the overall eating experience. Therefore, when mass-producing navel orange pastries, it is necessary to sieve the flour first.

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

During the reciprocating tilting process of the first filter screen, the flour lumps piled up at the high position of the first filter screen due to centrifugal vibration will be driven to slide towards the low position of the first filter screen, so that the flour state piled up at the edge is flattened to the low position on the first filter screen, thereby increasing the contact area between the flour lumps and the first filter screen, enhancing the efficiency of vibration crushing, and further improving the screening efficiency.

Detailed implementation manners

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] Embodiment:

[0031] Refer to Figures 1-7 , a low-gluten flour sieve with a double-layer screen staggered vibration structure for the production of navel orange pastries, comprising:

[0032] A screening part, the screening part includes a base 1, a hopper 2 is fixedly connected to the base 1, two vibration motors (prior art, when the two vibration motors move synchronously, centrifugal vibration will be generated on the hopper 2) are symmetrically and fixedly connected to the outside of the hopper 2 through connecting seats, two discharge channels are also symmetrically and fixedly connected to the outer side wall of the hopper 2, the discharge channels and the vibration motors are mutually misaligned, and a screening unit 3 is connected inside the hopper 2.

[0033] The inclined part, the inclined part includes a central axis 4, the screening unit 3 is connected with the central axis 4, the lower end of the central axis 4 is fixedly connected with a reduction motor through a coupling, and the upper end of the central axis 4 is connected with a deflection unit 5.

[0034] Among them, the deflection unit 5 includes a transmission ring 51, the transmission ring 51 is fixedly sleeved on the central axis 4 in a posture inclined to the axis through a connecting piece, so that when viewed directly from above perpendicular to the central axis 4, the transmission ring 51 presents a circular shape, the transmission ring 51 is connected with an inclined component 52, the top of the central axis 4 is connected with the screening unit 3 through a connecting component 53, and when the transmission ring 51 rotates, it will drive the screening unit 3 to swing reciprocally through the inclined component 52 and the connecting component 53.

[0035] During specific implementation, the flour to be screened is poured into the screening unit 3, two vibration motors operate synchronously, driving the silo 2 and the screening unit 3 to vibrate centrifugally synchronously to vibrate and crush the flour. Among them, a part of the flour with smaller particle size directly falls into the bottom of the silo 2 through the screening unit 3 and slides down from the discharge channel to the external container below with the centrifugal vibration of the silo 2, and the other part of the flour blocks that cannot pass through are 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 broken into a particle size that can pass through the screening unit 3.

[0036] While the silo 2 is vibrating centrifugally, the reduction motor also works synchronously, driving the central axis 4 to rotate at a relatively slow speed through the coupling (the coupling is an elastic coupling to avoid the vibration on the silo 2 and the screening unit 3 from being conducted 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 inclined component 52 and the connecting component 53, promoting the flour blocks piled up 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.

[0037] The screening unit 3 includes a waist-shaped container 31, the waist-shaped container 31 is fixedly connected to the inner wall of the silo 2, the bottom of the waist-shaped container 31 is fixedly connected with a first filter screen 32, the inner wall of the silo 2 and below the first filter screen 32 is fixedly connected with a second filter screen 33, the upper end of the waist-shaped container 31 is fixedly connected with an annular baffle 34, and the waist-shaped container 31 and the silo 2 are jointly connected with a crushing component 35.

[0038] The crushing component 35 includes a folding rod 351, the folding rod 351 adopts an open design and two are symmetrically and fixedly connected to the inner side wall of the waist-shaped container 31, a telescopic module 352 is jointly connected on the two straight line segments of the folding rod 351, the telescopic module 352 is connected with a crushing module 353, and the arc segment of the folding rod 351 and the silo 2 are jointly connected with a knocking module 354.

[0039] The telescopic module 352 includes a bidirectional movable spring rod 3521. The bidirectional movable spring rod 3521 is slidably connected between two straight segments of the folding rod 351. Two movable blocks 3522 are symmetrically and slidably connected to the fixed segment of the bidirectional movable spring rod 3521. A crushing module 353 is commonly connected between the movable blocks 3522.

[0040] The crushing module 353 includes a mounting rod 3531. The mounting rod 3531 is slidably and penetratingly connected between the movable blocks 3522. A plurality of mounting rings 3532 are slidably connected to the mounting rod 3531 along its length direction. A crushing rod 3533 is fixedly connected to the lower end of the mounting ring 3532. Springs are commonly connected between adjacent mounting rings 3532.

[0041] The knocking module 354 includes a guide rod 3541. Three guide rods 3541 are fixedly connected to the fixed segment of the bidirectional movable spring rod 3521 at equal intervals. The guide rod 3541 slidably penetrates through the arc segment 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. The knocking weight 3542 is located outside the silo 2.

[0042] The inclination assembly 52 includes an annular track 521. The annular track 521 is opened on the circumferential outer surface of the transmission ring 51. Two balls 522 are symmetrically and slidably fitted in the annular track 521. A vertical rod 523 is fixedly connected to the ball 522. The upper end of the vertical rod 523 is rotatably connected to a sliding seat. The sliding seat is slidably connected to the second filter screen 33.

[0043] The connection assembly 53 includes a fixed seat 531. A fixed seat 531 is commonly fixedly connected to the central positions of the first filter screen 32 and the second filter screen 33. The upper end of the central shaft 4 is connected to the fixed seat 531 through a spherical hinge. A limiting frame 532 is rotatably sleeved on the central shaft 4. The limiting frame 532 is slidably connected to the vertical rod 523. A corrugated seat 533 is commonly fixedly connected to the lower end of the fixed seat 531 and the limiting frame 532. Under the action of the corrugated seat 533, when the central shaft 4 rotates, the limiting frame 532, the vertical rod 523 and the ball 522 are always in a static state.

[0044] During specific implementation, the reduction motor operates to drive the central shaft 4 to rotate through a coupling. When the central shaft 4 rotates, it drives the transmission ring 51 to rotate synchronously through a connecting member. Since the transmission ring 51 is inclined, relative rotation will occur between the transmission ring 51 and the ball 522 when the transmission ring 51 rotates. As a result, the vertical rod 523 connected thereto is driven to move upward or downward by the ball 522 (during this process, the sliding seat will adaptively slide to compensate for the displacement caused by deflection between it and the second filter screen 33), and then the first filter screen 32, the second filter screen 33, the waist-shaped container 31, and the feed bin 2 are driven to reciprocally tilt around the connection between the central shaft 4 and the fixed seat 531.

[0045] When the first filter screen 32 is tilted, if the flour lumps piled up at its edge due to centrifugal vibration are located at a high position, they will roll towards the center of the first filter screen 32 under the action of their own gravity. During this process, multiple flour lumps will be laid flat on the first filter screen 32, thereby increasing the contact area between the flour lumps and the first filter screen 32, improving the vibration crushing efficiency, and promoting the rapid crushing and falling of the flour lumps.

[0046] When the feed bin 2 and the waist-shaped container 31 are tilted, they will drive the guide rod 3541 and the knocking weight 3542 to tilt synchronously. When the knocking weight 3542 located at a low position tilts, it moves away from the feed bin 2 under the action of its own gravity, thereby driving the two-way movable spring rod 3521 connected thereto through the guide rod 3541 located at a low position to move towards the feed bin 2. Since the folding rod 351 is of an open design, the two ends of the two-way movable spring rod 3521 located at a low position will automatically contract during the movement, driving the two movable blocks 3522 on its fixed section to move in the same direction, thereby driving the installation rings 3532 on the low-position installation rod 3531 to gradually approach each other. The springs between the adjacent two installation rings 3532 located at a low position are also gradually compressed. During this process, the distances between the various crushing rods 3533 located at a low position also gradually approach each other, crushing the larger flour lumps that cannot pass through the crushing rods 3533 during the downward sliding process. During the process of the low-position crushing rods 3533 continuing to move towards the waist-shaped container 31, they will also crush the flour lumps piled up at a low position, thereby further accelerating the crushing of the flour lumps.

[0047] When the silo 2 and the waist-shaped container 31 are tilted, the knocking weight 3542 located at the higher 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 cause the silo 2 to vibrate. At the same time, the waist-shaped container 31, the first filter screen 32 and the second filter screen 33 also vibrate synchronously, promoting the flour to pass through the first filter screen 32 and the second filter screen 33 to avoid the flour from blocking the first filter screen 32 and the second filter screen 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, the time and knocking of the knocking weights 3542 reaching the outer wall of the silo 2 are different. In this way, multiple knocks are completed in a single tilt, further improving the feeding efficiency.

[0048] It should be noted that the low-gluten flour sieve of the double-layer sieve staggered vibration structure for navel orange cake production has the following advantages:

[0049] Advantage 1: In this embodiment, the reduction motor works to drive the central shaft 4 to rotate through the coupling, so that the connecting piece drives the transmission ring 51 to rotate synchronously. Since the transmission ring 51 is inclined, relative rotation will occur between it and the ball 522 when it rotates. Thus, the two vertical rods 523 connected to the two balls 522 are driven to move synchronously and in opposite directions, and then the first filter screen 32, the second filter screen 33, the waist-shaped container 31 and the silo 2 are driven to reciprocally tilt around the connection between the central shaft 4 and the fixed seat 531. During the reciprocating tilt of the first filter screen 32, the flour lumps piled up at the higher position of the first filter screen 32 due to centrifugal vibration will be driven to slide towards the lower part of the first filter screen 32, so that the flour lumps change from the piled-up state to the flat state, thereby increasing the contact area between the flour lumps and the first filter screen 32 and enhancing the efficiency of vibration crushing.

[0050] Advantage 2: In this embodiment, when the silo 2 and the waist-shaped container 31 are tilted, the guide rods 3541 and the knocking weights 3542 will be driven to tilt synchronously. When the knocking weight 3542 at the lower position tilts, it drives the lower guide rod 3541 and the bidirectional movable spring rod 3521 connected to it to move towards the silo 2 under the action of its own gravity, thereby driving the lower bidirectional movable spring to automatically contract and driving the two movable blocks 3522 on its fixed section to move in the same direction, thereby driving the mounting rings 3532 and the crushing rods 3533 on the lower mounting rod 3531 to gradually approach, crushing the larger flour lumps that cannot pass through the crushing rods 3533 during the downward sliding process. During the process of the lower crushing rod 3533 continuing to move towards the waist-shaped container 31, it will also crush the smaller flour lumps piled up at the lower position and close to the hopper, thereby further accelerating the crushing of the flour lumps.

[0051] Advantage 3. In this embodiment, when the silo 2 and the waist-shaped container 31 are tilted, the knocking weight 3542 located at a higher 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 cause the silo 2 to vibrate. At the same time, the waist-shaped container 31, the first filter screen 32, and the second filter screen 33 also vibrate synchronously. On the one hand, it promotes the flour to pass through the first filter screen 32 and the second filter screen 33 to avoid the flour from clogging the first filter screen 32 and the second filter screen 33. On the other hand, it promotes the flour blocks that freely roll to a lower position and fit with the waist-shaped container 31 to break.

[0052] Advantage 4. In this embodiment, when the silo 2 is tilted, the discharge channel will also be tilted. The flour that accumulates at the bottom of the silo 2 after screening will quickly slide down to a lower position as the silo 2 tilts, and fall along the discharge channel at the lower position into the external container below. Compared with the conventional centrifugal discharge method, the discharge efficiency is higher.

[0053] 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 foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and 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 various embodiments of the present invention.
