Description

Technical Field

[0001] This utility model relates to the field of formulated food processing technology, specifically to a raw material screening device for formulated foods. Background Technology

[0002] Formulated foods are foods that have been specially processed and formulated to meet the nutritional needs of specific populations or specific physiological stages. During the production and processing of formulated foods, in order to improve the refinement of the formula ingredients, it is necessary to filter the raw materials used through a screening device.

[0003] Publication No. CN221335273U discloses a raw material screening device for special medical purpose formula foods. This device, through the connection of an electric push rod and a toothed plate, drives multiple gears to rotate as the toothed plate moves. This causes multiple rotating shafts to rotate within the screening box, resulting in multiple top blocks that lift the first, second, and third screen frames, tilting them with the assistance of connecting shafts. As the top blocks move away from the screen frames, they fall back down. This continuous falling and rising motion performs multi-layer screening of the raw materials, ensuring that materials of different particle sizes are adequately screened, avoiding incomplete filtration and the need for further processing, thus improving the device's effectiveness. However, this patent still has the following problems in practical use:

[0004] This device connects an electric push rod to a toothed plate, which drives multiple gears to rotate as the toothed plate moves. This causes multiple rotating shafts to rotate within the screening box, resulting in multiple top blocks that lift the first, second, and third screen frames. This continuous falling and rising motion allows for multi-layer screening of the raw materials, ensuring that materials of different particle sizes are adequately screened. However, when workers pour raw materials into the equipment, they tend to accumulate between the screening box and the screen frames. Even with the screen frames swaying up and down, some raw materials may not be evenly screened, affecting the screening effect of formulated foods and limiting the usability of the equipment.

[0005] A raw material screening device for formulated foods is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a raw material screening device for formulated foods, to solve the problems mentioned in the background art. Currently, the device uses an electric push rod connected to a toothed plate, which drives multiple gears to rotate as the toothed plate moves. This causes multiple rotating shafts to rotate within the screening box, resulting in multiple top blocks lifting the first, second, and third screen frames. This continuous falling and rising action allows for multi-layer screening of the raw materials, ensuring that materials of different particle sizes are adequately screened. However, when workers pour the raw materials into the equipment, they tend to accumulate between the screening box and the screen frames. Even with the screen frames swaying up and down, some materials cannot be evenly screened, thus affecting the screening effect of the formulated foods and limiting the usability of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a raw material screening device for formulated food, comprising a shell, wherein a feeding hopper is installed inside the top of the shell, and a discharge pipe is provided inside the bottom of the shell; a screening mechanism is provided inside the shell, and a discharge component is provided inside one side of the shell;

[0008] The screening mechanism includes trapezoidal plates symmetrically arranged on both sides of the inner shell, with screens installed between the trapezoidal plates. A fixed box is installed inside the shell, and a rotating rod is rotatably connected to the fixed box. A drive rod is slidably connected inside the screen, with its bottom end penetrating the fixed box and rotatably connected to it. A first rotating tooth is installed on the outer side of the rotating rod, and a second rotating tooth is installed at the bottom end of the drive rod. A stirring blade is installed on the top outer side of the drive rod, and elliptical plates are installed on the outer side of each rotating rod. A rubber sleeve is installed on one end of each elliptical plate, and a first sprocket is installed on one end of the rotating rod. A first chain is meshed between the outer sides of the first sprockets, and a motor is installed at one end of the rotating rod.

[0009] Preferably, the inner side of the housing is symmetrically provided with sliding grooves, and a slider is installed on one side of the trapezoidal plate. A fixed rod is installed inside the sliding groove, and the slider is slidably connected to the outside of the fixed rod. A first telescopic spring is sleeved on the outside of the fixed rod.

[0010] Preferably, the discharge assembly includes discharge ports all opened inside one side of the housing, and a sealing plate is inserted inside the discharge port. Support plates are symmetrically installed on one side of the housing. Limit boxes are symmetrically installed inside both ends of the support plates. A screw is threadedly connected to one side of the bottom end of the limit box. A push block is installed at one end of the screw. An inclined plate is slidably connected inside one side of the limit box. An insert block is installed on one side of the inclined plate. Slots are symmetrically opened on both sides of the sealing plate. The insert block is inserted into the slot.

[0011] Preferably, a guide groove is provided inside one end of the limiting box, and a guide block is slidably connected inside the guide groove. One end of the inclined plate is fixedly connected to the guide block, and a second telescopic spring is installed between the guide block and the guide groove.

[0012] Preferably, a second sprocket is installed at the end of the rotating rod away from the motor, and a second chain is meshed between the outer sides of the second sprocket.

[0013] Preferably, a rotating block is installed at the end of the screw away from the push block.

[0014] Preferably, the first rotating tooth and the second rotating tooth are meshed together.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The raw material screening device for formulated food comprises the following: The operator starts a motor to drive the rotating rod to rotate. Through the cooperation of the first sprocket and the first chain, multiple sets of rotating rods are driven to rotate. The rotation of the first rotating tooth drives the rotation of the second rotating tooth. The rotation of the drive rod drives the rotation of the stirring blades. The rotation of the stirring blades stirs and screens the raw material at the top of the screen. Furthermore, the rotation of the rotating rod drives the rotation of multiple sets of elliptical plates. The off-center rotation of the elliptical plates causes the rubber sleeve to beat the screen, thereby achieving the effect of vibratory screening of the raw material. This enables rapid screening of various specifications of formulated food. The mixing and vibrating sieving of food significantly improves the sieving efficiency of formulated foods and effectively enhances the uniformity of raw material sieving. This provides convenience for operators. By rotating two sets of screws inside the limiting box, the rotation of the screws causes the pusher blocks to press against the inclined plate. The inclined plate then slides inside the limiting box, causing multiple sets of insert blocks to engage with slots, thus quickly fixing the limiting sealing plate. This allows operators to easily open and close the discharge port, facilitating the collection of the sieved formulated food from the top of the screen, providing convenience for operators.

[0016] 1. The motor is started by the operator, driving the rotating rod to rotate. This rotation drives the first sprocket, which, in turn, along with the first chain, drives multiple sets of rotating rods. The rotation of these rods drives the first rotating tooth, which in turn drives the second rotating tooth. The second rotating tooth then drives the drive rod, which in turn drives the stirring blades. The stirring blades agitate and screen the material at the top of the screen. The rotation of the rotating rods also drives multiple sets of elliptical plates. The off-center rotation of these elliptical plates causes the rubber sleeves to beat the screen, achieving a vibratory screening effect. After being screened by multiple sets of screens with different apertures, the material is discharged through the discharge pipe. This device enables rapid mixing and vibrating screening of various specifications of formulated foods, thereby significantly improving screening efficiency and uniformity of raw materials. It also provides convenience for operators. When the elliptical plate strikes the screen, the screen is moved by the slapping, causing the trapezoidal plate to move. This movement of the trapezoidal plate causes the slider to slide outside the fixed rod. Simultaneously, the first telescopic spring contracts or extends, and the drive rod slides inside the screen, thus buffering the screen. Furthermore, the design of the rubber sleeve and the first telescopic spring effectively prevents damage caused by rigid contact between the elliptical plate and the screen, greatly extending the device's lifespan and enhancing its practicality for operators.

[0017] 2. The worker inserts the sealing plate into the inside of the discharge port, between the support plates. Then, the worker rotates two sets of screws inside the limiting box. The rotation of the screws causes the push block to press against the inclined plate, which then slides inside the limiting box. This allows multiple sets of inserts to engage with the slots, quickly fixing the sealing plate and facilitating the opening and closing of the discharge port. This also facilitates the collection of the sieved food from the top of the screen, providing convenience for workers. The movement of the inclined plate causes the guide block to slide inside the guide groove, extending the second telescopic spring. When the screw rotates in the opposite direction, causing the push block to retract, the second telescopic spring quickly contracts and resets. The guide block then pulls the inclined plate to slide inside the limiting box, quickly resetting the inserts and facilitating secondary operations on the inserts. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 The present invention provides a technical solution: a raw material screening device for formulated food, including a shell 1, a feeding hopper 101 installed inside the top of the shell 1, and a discharge pipe 102 provided inside the bottom of the shell 1; a screening mechanism 2 is provided inside the shell 1, and a discharge component 3 is provided inside one side of the shell 1.

[0027] The screening mechanism 2 includes trapezoidal plates 201, which are symmetrically arranged on both sides of the interior of the housing 1. Screens 202 are installed between the trapezoidal plates 201. Fixed boxes 203 are installed inside the housing 1, and rotating rods 204 are rotatably connected to the fixed boxes 203 and the housing 1. A drive rod 205 is slidably connected inside the screens 202, and the bottom end of the drive rod 205 passes through and is rotatably connected to the fixed boxes 203. A first rotating tooth 206 is installed on the outer side of the rotating rod 204, and a second rotating tooth 207 is installed on the bottom end of the drive rod 205. The first rotating tooth 206 and the second rotating tooth 207... The drive rod 205 is connected by interlocking meshing, and a stirring blade 208 is installed on the top outer side of the drive rod 205. Elliptical plates 209 are installed on the outer side of the rotating rod 204, and a rubber sleeve 210 is installed on the outer side of one end of the elliptical plate 209. A first sprocket 211 is installed on the outer side of one end of the rotating rod 204, and a first chain 212 is meshed between the outer sides of the first sprockets 211. A motor 213 is installed on one end of the rotating rod 204. This enables the rapid stirring and vibrating screening of various specifications of formula food, thereby greatly improving the screening efficiency of formula food and effectively improving the uniformity of raw material screening, bringing convenience to the staff during use.

[0028] The inner side of the housing 1 is symmetrically provided with sliding grooves 214, and a slider 215 is installed on one side of the trapezoidal plate 201. A fixed rod 216 is installed inside the sliding groove 214, and the slider 215 is slidably connected to the outside of the fixed rod 216. A first telescopic spring 217 is sleeved on the outside of the fixed rod 216. When the elliptical plate 209 beats the screen 202, the screen 202 is beaten and the trapezoidal plate 201 moves. The movement of the trapezoidal plate 201 causes the slider 215 to slide outside the fixed rod 216. At this time, the first telescopic spring 217 contracts or extends, and the drive rod 205 slides inside the screen 202, thereby realizing the movement of the screen 202. The design of the rubber sleeve 210 and the first telescopic spring 217 provides a buffering effect, effectively preventing damage caused by rigid contact between the elliptical plate 209 and the screen 202, thus greatly improving the service life of the device and enhancing its practicality for operators. A second sprocket 218 is installed at the end of the rotating rod 204 away from the motor 213, and a second chain 219 is meshed between the outer sides of the second sprocket 218. The rotation of the rotating rod 204 drives the rotation of the second sprocket 218. Through the cooperation between the second sprocket 218 and the second chain 219, the rotation of multiple sets of rotating rods 204 becomes more stable, improving the rotation accuracy of the rotating rods 204.

[0029] The discharge assembly 3 includes discharge ports 301 all located inside one side of the housing 1, with a sealing plate 302 inserted inside each discharge port 301. Support plates 303 are symmetrically installed on one side of the housing 1, and limit boxes 304 are symmetrically installed inside both ends of the support plates 303. A screw 305 is threadedly connected to the bottom of one side of the limit box 304, and a push block 306 is installed at one end of the screw 305. An inclined plate 307 is slidably connected inside one side of the limit box 304, and an insert block 308 is installed on one side of each inclined plate 307. Slots 309 are symmetrically opened on both sides of the sealing plate 302, and the insert blocks 308 are inserted into the slots 309. This allows for quick fixing of the limit sealing plate 302, facilitating the opening and closing of the discharge ports 301 and the sieving of the pre-sorted mixture at the top of the screen 202. The food is collected in a convenient manner for staff. The movement of the inclined plate 307 causes the guide block 311 to slide inside the guide groove 310. At this time, the second telescopic spring 312 extends. The guide groove 310 is opened inside one end of the limiting box 304, and the guide block 311 is slidably connected inside the guide groove 310. One end of the inclined plate 307 is fixedly connected to the guide block 311, and the second telescopic spring 312 is installed between the guide block 311 and the guide groove 310. When the screw 305 rotates in the opposite direction and the push block 306 retracts, the second telescopic spring 312 quickly contracts and resets. Then, the guide block 311 pulls the inclined plate 307 to slide inside the limiting box 304, thereby achieving the effect of quick reset of the insert block 308. This facilitates the secondary operation of the insert block 308 by the staff. A rotating block 313 is installed at the end of the screw 305 away from the push block 306.

[0030] Working principle: Before using this raw material screening device for formulated foods, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, firstly, the worker pours the raw material into the housing 1 through the feed hopper 101. At this time, the raw material accumulates on the top screen 202. Then, the worker starts the motor 213, which drives the rotating rod 204 to rotate. The rotation of the rotating rod 204 drives the first sprocket 211 to rotate. Through the cooperation of the first sprocket 211 and the first chain 212, multiple sets of rotating rods 204 are driven to rotate. The rotation of the rotating rod 204 drives the first rotating tooth 206 to rotate. The rotation of the first rotating tooth 206 drives the second rotating tooth 207 to rotate. The rotation of 207 drives the rotation of drive rod 205, which in turn drives the rotation of stirring blade 208. The rotation of stirring blade 208 stirs and screens the raw material at the top of screen 202. The rotation of rotating rod 204 then drives the rotation of multiple sets of elliptical plates 209. The off-center rotation of the elliptical plates 209 causes the rubber sleeve 210 to beat the screen 202, thus achieving the effect of vibratory screening of the raw material. After being screened by multiple sets of screens 202 with different apertures, the raw material is discharged through discharge pipe 102, thus achieving rapid screening. This device rapidly mixes and vibrates various specifications of formulated food products, significantly improving screening efficiency and uniformity. It also provides convenience for operators. When the elliptical plate 209 taps the screen 202, the screen 202 is moved by the tapping, causing the trapezoidal plate 201 to move. This movement of the trapezoidal plate 201 causes the slider 215 to slide outside the fixed rod 216. Simultaneously, the first telescopic spring 217 contracts or extends, and the drive rod 205 slides inside the screen 202, thereby... This design effectively buffers the screen 202. Furthermore, the design of the rubber sleeve 210 and the first telescopic spring 217 effectively prevents damage caused by rigid contact between the elliptical plate 209 and the screen 202, thereby greatly improving the service life of the device and enhancing its practicality for operators. The rotation of the rotating rod 204 drives the rotation of the second sprocket 218. Through the cooperation between the second sprocket 218 and the second chain 219, the rotation of multiple sets of rotating rods 204 becomes more stable, improving the rotation accuracy of the rotating rods 204.

[0031] The sealing plate 302 is inserted into the inside of the discharge port 301 by the operator. The sealing plate 302 is then inserted between the support plates 303. The operator then rotates two sets of screws 305 inside the limiting box 304. The rotation of the screws 305 causes the pusher block 306 to press against the inclined plate 307. The inclined plate 307 then slides inside the limiting box 304, causing multiple sets of insert blocks 308 to engage with the slots 309. This achieves the effect of quickly fixing the limiting sealing plate 302, thus facilitating the opening and closing of the discharge port 301 by the operator. The screen is closed, making it convenient for staff to collect the sieved food from the top of the screen 202, which brings convenience to the staff during use. The movement of the inclined plate 307 drives the guide block 311 to slide inside the guide groove 310. At this time, the second telescopic spring 312 extends. When the screw 305 rotates in the opposite direction and the push block 306 retracts, the second telescopic spring 312 quickly contracts and resets. Then, the guide block 311 pulls the inclined plate 307 to slide inside the limit box 304, thereby achieving the effect of quick reset of the insert block 308, which facilitates the secondary operation of the insert block 308 by the staff.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
