Description

Technical Field

[0001] The present invention belongs to the technical field of chili powder production, and specifically relates to a chili powder production device and method based on continuous and efficient screening. Background Art

[0002] During the production of chili powder, it is necessary to dry the washed and stemmed chili peppers to ensure their dryness for subsequent processing. Then, a crusher is used to crush the dried chili peppers into powder, and a screening machine is used to classify the crushed chili powder to remove impurities and large particles. Subsequently, the screened chili powder is packaged and usually stored in sealed plastic bags or metal cans.

[0003] After retrieval, a patent with the publication number CN118925913B discloses a chili powder production device based on continuous and efficient screening, including: a feeding box, a grinding machine, and three screening boxes. The feeding box is connected to the grinding machine through a feeding pipe, and the grinding machine is connected to the three screening boxes through distribution pipes. Front covers and rear covers are respectively provided on the front and rear sides of the three screening boxes. A miscellaneous material pipe is connected to the front side of the front cover, and an inclined screen cylinder is installed inside the screening box. In addition, a rotating shaft is installed on the rear cover, and a plurality of screening plates are fixedly installed on the rotating shaft for screening chili powder. The present invention has the advantages of large-scale industrialization, semi-automation, small floor area, simple operation, few workers, low power consumption, dust-free production, low noise, stable products, low technical requirements for workers, and low investment.

[0004] However, the above technical solution still has certain defects. The screening plates are made of hard materials. During the production process, when the chili powder passes through the screen barrel, some chili powder is squeezed by the screening plates. The chili powder extruded from the screen barrel will agglomerate, and the chili powder is easily blocked in the mesh holes of the screen barrel, resulting in a decrease in screening efficiency and affecting the production efficiency of chili powder.

[0018] The production method of the above-mentioned chili powder production device based on continuous and efficient screening is as follows:

[0019] Open the cover plate. Wait until the ground chili peppers are added to the inside of the grinding bin. Start the second motor to drive the rotating shaft to rotate, so that the rotating shaft drives the grinding roller to roll on the top of the turning plate. Relying on the weight of the grinding roller and the ridges on the outer wall of the grinding roller, the chili peppers are ground into chili powder.

[0020] The ground chili peppers slide into the inner frame. During the process of the first motor driving the synchronous wheel to rotate, multiple groups of synchronous wheels and synchronous belts cooperate to make the rotating frame and the gear set rotate, so that the eccentric wheel rotates. During the rotation of the eccentric wheel, the whole inner frame shakes, and the rotating frame drives the brush to slide across the inner wall of the metal screen.

[0021] Place the whole chili powder production device under the conveyor belt, so that the screened chili powder falls on the conveyor belt, and the produced chili peppers are respectively conveyed to the subsequent processes.

[0022] Compared with the prior art, the present invention mainly has the following beneficial effects:

[0023] 1. In a chili powder production device based on continuous and efficient screening according to the present invention, by setting a rotating frame and a brush, during use, the chili powder inside the metal screen is continuously stirred. And since the brush has a certain flexibility, it avoids the chili powder being extruded out of the metal screen by hard extrusion. During the above process, the eccentric wheel rotates continuously. Since the center of gravity of the eccentric wheel moves continuously during rotation, the vibration block drives the inner frame to shake continuously, so that the chili powder inside the metal screen can be screened by the metal screen more quickly. And because the outer frame and the inner frame are connected by a first turntable and a second turntable, and the first turntable and the second turntable are connected by a first rubber rod, it is not easy for the outer frame to shake when the inner frame shakes continuously, ensuring that the chili powder production device can be stably placed on the ground;

[0024] 2. After putting the chili to be milled into the inside of the milling chamber, the milling roller inside the milling chamber continuously mills the chili and grinds it into powder. And during the above process, the scraping plate continuously pushes the chili to between the inner wall of the milling chamber and the rotating shaft, so that the middle position of the milling chamber can always fully mill the chili. Compared with the traditional multi-layer blade type crushing method, when crushing chili, some chili will be deposited at the bottom of the crushing chamber and cannot be fully crushed by the blades. After the chili is milled into powder by this chili powder production device, the hydraulic rod is used to make the flap turn over, so that the milled chili powder can slide down, improving the milling efficiency and effect. And the inner frame and the milling chamber are connected by a rubber sleeve to avoid the shaking of the inner frame being transmitted to the milling chamber;

[0025] 3. In a chili powder production device based on continuous and efficient screening according to the present invention, during the milling process, the upper abutting disc is driven to rotate, so that the connecting shaft beside the metal screen rotates continuously back and forth, making the rubber wheel continuously knock on the metal screen. And the metal screen has a certain flexibility. At this time, the metal screen will deform to a certain extent when being knocked, and then rebound under its own elastic force, thereby further accelerating the screening speed of the chili powder.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and cannot be understood as a limitation to the present invention.

[0038] An embodiment of a chili powder production device based on continuous and efficient screening according to the present invention will be described below with reference to its overall structure.

[0039] A chili powder production device based on continuous and efficient screening, as Figures 1 to 10 shown, includes a screening mechanism 1. The screening mechanism 1 includes an outer frame 101. At least four groups of first motors 103 are fixedly connected to the outer wall of the outer frame 101. The output end of each group of first motors 103 is respectively fixedly connected to a group of first turntables 104. Multiple groups of first turntables 104 are respectively rotatably connected to both sides of the outer frame 101.

[0040] An inner frame 102 is sleeved on the inner wall of the outer frame 101. At least four groups of second turntables 106 are rotatably connected to the side wall of the inner frame 102. Each group of second turntables 106 is respectively close to a group of first turntables 104. Multiple groups of first rubber rods 105 are respectively fixedly connected to the side wall of each group of second turntables 106, and the ends of multiple groups of first rubber rods 105 are fixedly connected to the side wall of the nearest group of first turntables 104.

[0041] Multiple groups of rotating frames 107 are rotatably connected to the inner wall of the inner frame 102. The end of each group of rotating frames 107 is respectively fixedly connected to the axis of a group of second turntables 106. A group of synchronous wheels 109 are respectively fixedly sleeved at the connection of each group of rotating frames 107 and the second turntables 106. Two vibration blocks 111 are fixedly sleeved inside the inner frame 102. The two vibration blocks 111 are respectively close to both sides of the inner frame 102. A gear set 112 is arranged on the inner wall of the vibration block 111. The output end of the gear set 112 is fixedly connected to an eccentric wheel 113. The input end of the gear set 112 is fixedly connected to another group of synchronous wheels 109. A group of synchronous belts 108 are sleeved on the outer walls of multiple groups of synchronous wheels 109 on the same side.

[0042] Two metal sieves 114 are fixedly connected to the bottom end of the inner frame 102. Multiple groups of brushes 110 are fixedly connected to the end of each group of rotating frames 107. The brushes 110 are attached to the inner wall of the metal sieve 114.

[0043] The first motor 103 drives the first turntable 104 to rotate, thereby driving the second turntable 106 through multiple groups of first rubber rods 105, and then driving the synchronous pulley 109 and the rotating frame 107 connected thereto to rotate. As a result, the rotating frame 107 drives the brush 110 to rotate. During the rotation of the rotating frame 107 and the brush 110, the chili powder above the metal screen 114 is continuously stirred, preventing the chili powder from accumulating on the metal screen 114. Moreover, the brush 110 has a certain flexibility, preventing the chili powder from being forcibly squeezed out of the metal screen 114. With the cooperation of the synchronous belt 108 and the synchronous pulley 109, a group of synchronous pulleys 109 coaxially connected to the gear set 112 drive the gear set 112 to rotate. During the rotation of the gear set 112, the eccentric wheel 113 is driven to rotate. Due to the special structure of the eccentric wheel 113, the vibration block 111 continuously shakes during the rotation of the eccentric wheel 113, driving the inner frame 102 to shake. Consequently, the entire inner frame 102 and the metal screen 114 shake, enabling the chili powder to be screened by the metal screen 114 more rapidly. Since the first turntable 104 and the second turntable 106 are connected by rubber rods, during the shaking of the inner frame 102, the first motor 103 can transmit power to the second turntable 106, and the shaking of the inner frame 102 is not likely to drive the outer frame 101 to shake.

[0044] Please refer particularly to Figures 1 to 5, a grinding mechanism 2 is arranged above the screening mechanism 1. The grinding mechanism 2 includes a grinding bin 201. The grinding bin 201 is fixedly connected to the top end of the outer frame 101. Two groups of rubber sleeves 202 are communicated at the bottom end of the grinding bin 201. The two groups of rubber sleeves 202 are communicated with the top end of the inner frame 102. Two semi-circular turning plates 203 are rotatably connected to the inner wall of the grinding bin 201. A hydraulic rod 204 is hinged to the bottom end of each turning plate 203. The bottom end of the hydraulic rod 204 extends to the outside of the grinding bin 201. The bottom end of the hydraulic rod 204 is hinged to the outer wall of the grinding bin 201. Two groups of cover plates 205 are hinged to the top end of the grinding bin 201. A rotating shaft 206 is rotatably connected to the inner wall of the grinding bin 201. The top end of the rotating shaft 206 extends out of the top end of the grinding bin 201. A second motor 210 is fixedly connected to the top end of the grinding bin 201. The output end of the second motor 210 is fixedly connected to the top end of the rotating shaft 206. The second motor 210 is located between the two groups of cover plates 205. The bottom end of the rotating shaft 206 extends out of the bottom end of the grinding bin 201. The bottom end of the rotating shaft 206 is connected to the screening auxiliary mechanism 3. A cross bar 208 is fixedly sleeved on the outer wall of the rotating shaft 206. A plurality of scraping plates 209 are fixedly connected to the bottom end of the cross bar 208. The plurality of scraping plates 209 are respectively distributed on both sides of the rotating shaft 206. The bottom end of the scraping plate 209 is attached to the top end of the turning plate 203. The plurality of scraping plates 209 on the same side are inclined between the rotating shaft 206 and the grinding bin 201. A grinding roller 207 is fixedly connected to each side of the cross bar 208. A plurality of convex strips are arranged on the outer wall of the grinding roller 207. And the grinding roller 207 is attached to the top end of the turning plate 203.

[0045] Open the cover plate 205 by flipping it, then add the washed and dried chili peppers to be ground into the interior of the grinding chamber 201. Then close the cover plate 205 and start the second motor 210, so that the second motor 210 drives the rotation of the rotating shaft 206. During the rotation of the rotating shaft 206, the rotating shaft 206 drives the rotation of the cross bar 208, thereby driving the grinding roller 207 to roll on the top of the turning plate 203. The grinding roller 207 continuously grinds the chili peppers into chili powder. During the above process, the cross bar 208 drives the scraping plate 209 to rotate, so that the scraping plate 209 slides on the top of the turning plate 203. Due to the inclined setting of the scraping plate 209, the chili peppers are gathered between the grinding chamber 201 and the rotating shaft 206, avoiding the chili peppers being too close to the interior of the grinding chamber 201 and also avoiding the chili peppers gathering near the rotating shaft 206, enabling the grinding roller 207 to fully grind the chili peppers; after the chili peppers are ground into chili powder, the hydraulic rod 204 contracts, pulling the turning plate 203 to turn downward. During the turning of the hydraulic rod 204, the chili powder slides from the surface of the turning plate 203 to the surface of the rubber sleeve 202, and then slides along the rubber sleeve 202 into the inner frame 102 and falls above the metal screen 114. Then the hydraulic rod 204 extends, causing the turning plate 203 to turn back and reset. At this time, the top edge of the turning plate 203 fits against the inner wall of the grinding chamber 201, and chili peppers can continue to be added to the interior of the grinding chamber 201.

[0046] Please refer specifically to Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9, the screening auxiliary mechanism 3 includes at least four sets of connecting shafts 301. The connecting shafts 301 are rotatably connected to the outer wall of the inner frame 102. Multiple sets of connecting shafts 301 are respectively close to both sides of the two metal screen meshes 114. A torsion spring is provided at the connection between the connecting shaft 301 and the inner frame 102. At the middle position of the outer wall of each set of connecting shafts 301, multiple sets of rotating arms 302 are respectively fixedly connected. At the end of each set of rotating arms 302, a set of rubber wheels 303 are respectively fixedly connected. The edge of the rubber wheel 303 abuts against the outer wall of the metal screen mesh 114. At both ends of each set of connecting shafts 301, a set of flipping rods 304 are respectively fixedly connected. At the end of each set of flipping rods 304, a set of connecting rods 305 are respectively rotatably connected. At the top of multiple sets of connecting rods 305 on the same side, a pressing plate 306 is rotatably connected. At the bottom end of each set of pressing plates 306, multiple sets of supporting springs 307 are respectively fixedly connected. The bottom end of the supporting spring 307 is fixedly connected to the outer wall of the inner frame 102. The inner wall of each set of pressing plates 306 is slidably sleeved on the outer wall of the guiding rod 313. The bottom end of the guiding rod 313 is fixedly connected to the outer wall of the inner frame 102. Multiple sets of supporting springs 307 are respectively located at the intervals between multiple sets of guiding rods 313. A cross beam 308 is fixedly connected between the two pressing plates 306. At the top of the cross beam 308, a lower abutting disc 309 is fixedly connected. At the top of the lower abutting disc 309, a lower convex block 310 is fixedly connected. Above the lower convex block 310, an upper abutting disc 311 is provided. The upper abutting disc 311 is rotatably connected to the outer wall of the inner frame 102. At the bottom end of the upper abutting disc 311, an upper convex block 312 is fixedly connected. At the top of the upper abutting disc 311, multiple sets of second rubber rods 314 are fixedly connected. The top end of the second rubber rod 314 is fixedly connected to the bottom end of the rotating shaft 206.

[0047] During the rotation of the rotating shaft 206, the rotating shaft 206 drives the upper abutting disc 311 to rotate through the second rubber rod 314, thereby driving the upper convex block 312 to rotate, so that the inclined surface of the upper convex block 312 contacts the inclined surface of the lower convex block 310, thereby causing the upper convex block 312 to push the lower convex block 310 downward, making the upper abutting disc 311 and the lower abutting disc 309 move away from each other, and the lower convex block 310 pushes the lower abutting disc 309 downward, and then pushes the cross beam 308 to make the pressing plate 306 slide downward, and the supporting spring 307 is compressed. During the process of the pressing plate 306 being pressed downward, the pressing plate 306 drives the turning rod 304 to rotate through the connecting rod 305, so that the turning rod 304 drives the connecting shaft 301 to rotate, and the connecting shaft 301 twists the torsion spring. During the rotation of the connecting shaft 301, the rotating arm 302 is driven to rotate, thereby driving the rubber wheel 303 away from the metal screen 114. When the upper convex block 312 completely slides past the lower convex block 310, the torsion spring and the supporting spring 307 rebound. At this time, the connecting shaft 301 rotates in the reverse direction, and the pressing plate 306 slides upward to reset. During the process of the connecting shaft 301 rotating in the reverse direction and resetting, the rotating arm 302 is driven to rotate in the reverse direction. Since the contact surface between the lower convex block 310 and the upper convex block 312 is a smooth inclined surface, and the separation part is a vertical surface, when the upper convex block 312 is separated from the lower convex block 310, the torsion spring and the supporting spring 307 rebound at a faster speed during the process, thereby driving the rubber wheel 303 to strike the outer wall of the metal screen 114, making the metal screen 114 vibrate under the strike, so that the chili powder can be screened more quickly.

[0048] The production method of the above-mentioned chili powder production device based on continuous and efficient screening is as follows:

[0049] Open the cover plate 205, wait to add the chili to be ground into the interior of the grinding bin 201, start the second motor 210, drive the rotating shaft 206 to rotate, so that the rotating shaft 206 drives the grinding roller 207 to roll on the top of the turning plate 203, and grind the chili into chili powder by means of the weight of the grinding roller 207 and the protrusions on the outer wall of the grinding roller 207;

[0050] The ground chili powder slides into the inner frame 102. During the process of the first motor 103 driving the synchronous wheel 109 to rotate, multiple groups of synchronous wheels 109 and synchronous belts 108 cooperate to make the rotating frame 107 and the gear set 112 rotate, thereby making the eccentric wheel 113 rotate. During the rotation of the eccentric wheel 113, the entire inner frame 102 shakes, and the rotating frame 107 drives the brush 110 to slide on the inner wall of the metal screen 114, avoiding the accumulation of chili powder inside the metal screen 114 and improving the screening efficiency of the chili powder;

[0051] The entire chili powder production device is installed below the conveyor belt, so that the screened chili powder falls onto the conveyor belt, enabling the produced chili to be separately conveyed to subsequent processes. The parts not involved in this device are the same as or can be implemented using the prior art.

[0052] Although the embodiments of the present invention have been shown and described, the specific embodiments are merely explanations of the present invention and not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
