Description

Technical Field

[0001] The present invention belongs to the technical field of food processing, and particularly relates to a raw material conveying device for food processing. Background Art

[0002] Food raw material processing refers to the process of treating natural or primary edible raw materials through physical, chemical or biological means to change their forms, properties or components, so as to obtain products that meet food standards, are convenient for storage or can be directly eaten. The raw materials cover animals, plants, microorganisms and their extracts, and the processing objectives include extending the shelf life, improving safety, enhancing sensory quality and nutritional value. However, a conveying device for meat block raw material processing refers to a special mechanical equipment or automated system used for safely, efficiently and hygienically transporting raw materials such as pig carcasses, cut meat blocks, internal organs, bones, etc. during the processes of meat block slaughtering, cutting, processing and packaging. Its core function is to achieve continuous transmission of raw materials between different processing links, while ensuring food safety, reducing pollution and improving production efficiency.

[0003] Currently, when conveying meat blocks for processing, a conveying mesh belt is usually used, which is not only convenient for cleaning but also can facilitate the drainage of blood in the meat blocks to avoid the meat quality from soaking and deteriorating. And in the existing conveying device, a cleaning mechanism is installed, which can automatically clean the conveying mesh belt. However, during the cleaning process, the dead corners of the conveying mesh belt cannot be cleaned, and when cleaning the residual minced meat on the conveying mesh belt with a rolling brush, it cannot be automatically cleaned. During the next cleaning process, the minced meat on the rolling brush affects the cleaning effect of the conveying mesh belt, and manual cleaning by staff is required, increasing the labor cost. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a raw material conveying device for food processing.

[0005] The technical solution adopted to solve the above technical problem is: a raw material conveying device for food processing, including a support frame, a conveying assembly is installed at the inner top end of the support frame, and a flushing mechanism is installed at the center inside the support frame;

[0006] A reciprocating mechanism is arranged at the center position inside the support frame and below the flushing mechanism, an inner brush mechanism is installed on the reciprocating mechanism, and an outer brush mechanism is installed at a position close to the lower side of the inner brush mechanism on the reciprocating mechanism.

[0007] Furthermore, a first outer shell is fixedly connected to the center of the front end of the support frame, a second outer shell is fixedly connected to the center of the rear end of the support frame, and a feeding funnel is fixedly connected to the inner bottom end of the support frame.

[0008] Through the above technical solution, the first housing and the second housing are used to protect the parts in the reciprocating mechanism and the outer brush mechanism. The blanking funnel can collect the minced meat scraped by the inner brush mechanism and the outer brush mechanism, and at the same time can also collect the waste water for flushing the conveying component, and both can be conveniently discharged.

[0009] Further, the conveying component includes a plurality of first rotating shafts rotatably connected to the center of the support frame. Both the front and rear ends of the outer walls of the plurality of first rotating shafts are fixedly connected with first sprockets. The front and rear ends of the plurality of first rotating shafts are respectively provided with first chains. The two first chains are respectively engaged with the corresponding first sprockets. A conveying mesh belt is fixedly connected between the two first chains. A first motor is fixedly installed at the top of one side of the front end of the support frame. The rear end of the output shaft of the first motor is fixedly connected to the front end of one of the first rotating shafts.

[0010] Through the above technical solution, when the meat block needs to be processed and conveyed, the meat block is placed on the conveying mesh belt, the first motor is started, the connected first rotating shaft is driven to rotate through the rotation of the output shaft, so as to drive the two connected first sprockets to rotate. The remaining first sprockets cooperate to drive the two first chains to rotate, so as to drive the conveying mesh belt to rotate, realizing the conveying of the meat block. At the same time, the conveying mesh belt can conveniently discharge the blood water in the meat block, avoiding the meat quality from soaking and deteriorating.

[0011] Further, the flushing mechanism includes two groups of water pipes rotatably connected to the center of the support frame. A plurality of nozzles are fixedly connected to both groups of water pipes. The rear ends of the two groups of water pipes are fixedly connected with Z-shaped shafts. Two fixing plates are fixedly connected to the center of the rear end of the support frame. Two limiting rods are fixedly connected to the inner sides of the two fixing plates. First fixing frames are fixedly connected to the rear end of the support frame respectively near the two fixing plates. Cylinders are fixedly installed on both first fixing frames. A first connecting pipe is rotatably connected between the two groups of water pipes. A second fixing frame is fixedly connected to the front end of the support frame. A water pump is fixedly installed on the top of the second fixing frame. A second connecting pipe is fixedly connected between the water pump and the first connecting pipe.

[0012] Through the above technical solution, when flushing the conveyor mesh belt, at the positions where the conveyor mesh belt is about to pass through multiple nozzles, the water pump is started. The water pump extracts external water source, transports it to the first connecting pipe through the second connecting pipe, and then transports it into two groups of water pipes. One group of water pipes first sprays and flushes the conveyor mesh belt through multiple nozzles. At the same time, the cylinders close to each other are started. The piston pushes the corresponding first connecting pipe, thereby pushing the two Z-shaped shafts on its inner wall, driving the two Z-shaped shafts to rotate, realizing the rotation of the group of water pipes close to the conveyor mesh belt, and realizing the rotary spraying and flushing of the conveyor mesh belt, which can wash away the blood or minced meat existing in the gaps of the conveyor mesh belt, avoid the residue of blood and minced meat, reduce the risk of microbial contamination, improve the quality of meat block transportation. After flushing, after being cleaned by the inner brush mechanism and the outer brush mechanism, the other group of water pipes will flush it in the same way through multiple nozzles, so as to clean the conveyor mesh belt after brushing again, greatly improving the cleaning effect of the conveyor mesh belt.

[0013] Further, one end of each of the two cylinder pistons is fixedly connected to the corresponding first connecting pipe, the rear ends of the outer walls of the multiple Z-shaped shafts are slidably connected to the corresponding first connecting pipes, and the multiple limiting rods respectively penetrate through the corresponding first connecting pipes.

[0014] Through the above technical solution, when the first connecting pipe is pushed, it is slidably connected to the corresponding two limiting rods, improving the stability during its movement.

[0015] Further, the reciprocating mechanism includes slide rails fixedly connected to the front and rear ends of the support frame. An activity frame is slidably connected between the two slide rails. A third fixed frame is fixedly connected to the front end of the support frame near the activity frame. A second motor is fixedly installed on the third fixed frame. A turntable is fixedly connected to the outer wall of the output shaft of the second motor. A connecting rod is rotatably connected to the rear end of the turntable. The other end of the connecting rod is rotatably connected to the activity frame. Multiple brush rods are fixedly connected to both ends of the center of the activity frame.

[0016] Through the above technical solution, when precise cleaning of the conveyor mesh belt is required, the second motor is started. The output shaft rotates to drive the turntable to rotate, thereby driving the connecting rod to rotate, driving the activity frame to slide on the two slide rails, driving the inner brush mechanism and the outer brush mechanism to reciprocate back and forth. Since the conveyor mesh belt is also in transmission, a two-way mechanical friction is formed, which can effectively remove the blood clots or minced meat adhered in the gaps and grooves of the conveyor mesh belt, realizing precise cleaning.

[0017] Further, the inner brush mechanism includes a connecting plate above the activity frame. A plate brush is fixedly connected to the center of the bottom of the connecting plate. Threaded rods are fixedly connected to the front and rear ends of the bottom of the connecting plate. Springs are fixedly connected to the outer sides of the threaded rods near the bottom of the connecting plate. Nuts are threadedly connected to the multiple threaded rods.

[0018] Through the above technical solution, when the conveyor belt is roughly cleaned, during the transmission of the conveyor belt, due to the unevenness of the conveyor belt, when touching the brush plate, buffering is carried out through multiple springs, and the downward pressure of the brush plate is automatically adjusted to achieve the cleaning of the inner wall of the conveyor belt. At the same time, scratches or abrasions caused by hard friction are avoided, the service life of the conveyor belt is extended, and it is ensured that the brush plate always closely adheres to the conveyor belt to maintain a stable cleaning effect.

[0019] Further, the bottom ends of the multiple springs are fixedly connected to the top of the movable frame, the multiple threaded rods all penetrate through the top of the movable frame, and the multiple nuts are all attached to the inner surface of the top of the movable frame.

[0020] Through the above technical solution, the downward pressure of the brush plate can be effectively controlled through multiple nuts, so as to maintain a certain force to effectively clean the conveyor belt and reduce scratches on the conveyor belt.

[0021] Further, the outer brush mechanism includes two second rotating shafts rotatably connected to the center of the movable frame. Second sprockets are fixedly connected to the front and rear ends of the outer walls of the two second rotating shafts. Second chains are installed between every two of the second sprockets. A plurality of third rotating shafts are rotatably connected between the two second chains. Brush rollers are fixedly installed on the outer walls of the plurality of third rotating shafts. Gears are fixedly connected to the front ends of the outer walls of the plurality of third rotating shafts. A mounting frame is fixedly connected to the inner surface of the front end of the movable frame. A rack is fixedly connected to the mounting frame. A third motor is fixedly installed on one side of the front end of the movable frame.

[0022] Through the above technical solution, when the conveyor belt is roughly cleaned, the third motor is started, and the connected second rotating shaft is driven to rotate through the rotation of the output shaft, so as to drive the two connected second sprockets to rotate, so as to drive the second chain to drive, realizing the driving of a plurality of brush rollers. Since the gear on the third rotating shaft of the brush roller meshes with the rack during the driving process, rotation is realized, so as to drive the brush roller to rotate, realizing the cleaning of the outer wall of the conveyor belt, so as to brush off the residual minced meat on the conveyor belt. When the root of the brush roller catches the minced meat brushed off, when passing through a plurality of brush rods, the brush roller will be deformed briefly, so as to eject the minced meat caught at its root, so as not to affect the next cleaning of the conveyor belt, greatly improving the cleaning effect.

[0023] Further, in the combined state, the multiple gears mesh with the rack, and the rear end of the output shaft of the third motor is fixedly connected to the front end of one of the second rotating shafts.

[0024] Through the above technical solution, when precision cleaning is required, in cooperation with the reciprocating mechanism, through a series of mechanical motion modes of reciprocating movement, self-rotation and transmission, the cleaning effect on the conveyor belt is greatly improved.

[0025] The beneficial effects of the present invention are as follows: (1) By designing an outer brush mechanism, an inner brush mechanism and a reciprocating mechanism, the present invention can clean the conveying mesh belt with coarseness and precision. During the normal conveying of meat blocks, coarse cleaning can be carried out, which not only does not affect the normal conveying of meat blocks, but also reduces the impact of broken meat. During precision cleaning, through reciprocating movement to form a two-way mechanical friction, it can effectively remove the blood clots or broken meat adhering in the gaps and grooves of the conveying mesh belt, greatly improving the cleaning efficiency; (2) Through the flushing mechanism, multi-angle flushing can wash away the blood or broken meat existing in the gaps of the conveying mesh belt, avoiding the residue of blood and broken meat, reducing the risk of microbial contamination, and improving the quality of meat block conveying.

The center of the front end of the support frame 1 is fixedly connected with a first outer shell 11, the center of the rear end of the support frame 1 is fixedly connected with a second outer shell 12, and the inner bottom end of the support frame 1 is fixedly connected with a blanking funnel 13. The first outer shell 11 and the second outer shell 12 are used for protecting the parts in the reciprocating mechanism 4 and the outer brush mechanism 6. The blanking funnel 13 can collect the minced meat scraped off by the inner brush mechanism 5 and the outer brush mechanism 6, and at the same time can also collect the waste water for flushing the conveying assembly 2, and both can be conveniently discharged.

[0042] As Figures 1 - 7As shown in the figure, a conveying component 2 is installed at the inner top of the support frame 1. The conveying component 2 includes a plurality of first rotating shafts 201 rotatably connected to the center of the support frame 1. First sprockets 202 are fixedly connected to the front and rear ends of the outer walls of the plurality of first rotating shafts 201. First chains 203 are provided at the front end and the rear end of the plurality of first rotating shafts 201. The two first chains 203 are respectively engaged with the corresponding first sprockets 202. A conveying mesh belt 204 is fixedly connected between the two first chains 203. A first motor 205 is fixedly installed at the top of one side of the front end of the support frame 1. The rear end of the output shaft of the first motor 205 is fixedly connected to the front end of one of the first rotating shafts 201. When the meat block needs to be processed and conveyed, the meat block is placed on the conveying mesh belt 204, and the first motor 205 is started. The connected first rotating shaft 201 is driven to rotate through the rotation of the output shaft, so as to drive the two connected first sprockets 202 to rotate. The remaining first sprockets 202 cooperate to drive the two first chains 203 to rotate, so as to drive the conveying mesh belt 204 to rotate, realizing the conveying of the meat block. At the same time, the conveying mesh belt 204 can facilitate the removal of the blood in the meat block and avoid the deterioration of the meat quality due to soaking.

[0043] As Figures 1 - 13As shown, a flushing mechanism 3 is installed at the inner center of the support frame 1. The flushing mechanism 3 includes two groups of water pipes 301 rotatably connected to the center of the support frame 1. A plurality of spray nozzles 302 are fixedly connected to both groups of water pipes 301. Z-shaped shafts 303 are fixedly connected to the rear ends of both groups of water pipes 301. Two fixing plates 304 are fixedly connected to the center of the rear end of the support frame 1. Two limiting rods 305 are fixedly connected to the inner sides of the two fixing plates 304. First fixing frames 306 are fixedly connected to the positions of the rear end of the support frame 1 close to the two fixing plates 304 respectively. Cylinders 307 are fixedly installed on both first fixing frames 306. A first connecting pipe 308 is rotatably connected between the two groups of water pipes 301. A second fixing frame 309 is fixedly connected to the front end of the support frame 1. A water pump 310 is fixedly installed on the top of the second fixing frame 309. A second connecting pipe 311 is fixedly connected between the water pump 310 and the first connecting pipe 308. When flushing the conveying mesh belt 204, at the positions where the conveying mesh belt 204 is about to pass through a plurality of spray nozzles 302, the water pump 310 is started. The water pump 310 extracts external water source and transports it to the first connecting pipe 308 through the second connecting pipe 311, and then transports it into the two groups of water pipes 301. One group of water pipes 301 first sprays and flushes the conveying mesh belt 204 through a plurality of spray nozzles 302. At the same time, the cylinders 307 close to each other are started. The piston pushes the connected first connecting pipe 308, thereby pushing the two Z-shaped shafts 303 on its inner wall, and driving the two Z-shaped shafts 303 to rotate, so as to realize the rotation of the group of water pipes 301 close to it, and realize the rotating water spraying and flushing of the conveying mesh belt 204, which can wash away the blood or minced meat existing in the gaps of the conveying mesh belt 204, avoid the residue of blood and minced meat, reduce the risk of microbial contamination, and improve the quality of meat block conveying. After flushing, after being cleaned by the inner brushing mechanism 5 and the outer brushing mechanism 6, the other group of water pipes 301 will flush it in the same way through a plurality of spray nozzles 302, so as to clean the conveying mesh belt 204 again after brushing, greatly improving the cleaning effect of the conveying mesh belt 204. One end of the pistons of the two cylinders 307 is fixedly connected to the corresponding first connecting pipe 308 respectively. The outer walls of the rear ends of the plurality of Z-shaped shafts 303 are slidably connected to the corresponding first connecting pipe 308. The plurality of limiting rods 305 respectively penetrate through the corresponding first connecting pipe 308. When the first connecting pipe 308 is pushed, it is slidably connected to the corresponding two limiting rods 305, improving the stability during its movement.

[0044] As Figures 1 - 11As shown in the figure, a reciprocating mechanism 4 is provided at the center of the flushing mechanism 3 inside the support frame 1. The reciprocating mechanism 4 includes slide rails 401 fixedly connected to the front and rear ends of the support frame 1. A movable frame 402 is slidably connected between the two slide rails 401. A third fixed frame 403 is fixedly connected to the front end of the support frame 1 near the movable frame 402. A second motor 404 is fixedly installed on the third fixed frame 403. An outer wall of an output shaft of the second motor 404 is fixedly connected to a turntable 405. A rear end of the turntable 405 is rotatably connected to a connecting rod 406. The other end of the connecting rod 406 is rotatably connected to the movable frame 402. A plurality of brush rods 407 are fixedly connected to both ends of the center of the movable frame 402. When precision cleaning of the conveyor belt 204 is required, the second motor 404 is started. The turntable 405 is driven to rotate by the rotation of the output shaft, thereby driving the connecting rod 406 to rotate, thereby driving the movable frame 402 to slide on the two slide rails 401, thereby driving the inner brush mechanism 5 and the outer brush mechanism 6 to reciprocate back and forth. Since the conveyor belt 204 is also in transmission, a two-way mechanical friction is formed, which can effectively remove blood clots or minced meat adhering to the gaps and grooves of the conveyor belt 204, achieving precision cleaning.

[0045] As Figures 1 - 10 As shown in the figure, an inner brush mechanism 5 is installed on the reciprocating mechanism 4. The inner brush mechanism 5 includes a connecting plate 501 above the movable frame 402. A plate brush 502 is fixedly connected to the center of the bottom of the connecting plate 501. Threaded rods 503 are fixedly connected to the front and rear ends of the bottom of the connecting plate 501. Springs 504 are fixedly connected to the outer sides of the threaded rods 503 near the bottom of the connecting plate 501. Nuts 505 are threadedly connected to the plurality of threaded rods 503. When rough cleaning of the conveyor belt 204 is performed, when the conveyor belt 204 is in transmission, since the conveyor belt 204 is uneven, when touching the plate brush 502, buffering is performed through the plurality of springs 504, automatically adjusting the downward pressure of the plate brush 502, realizing cleaning of the inner wall of the conveyor belt 204, and at the same time avoiding scratches or abrasions caused by hard friction, extending the service life of the conveyor belt 204, and ensuring that the plate brush 502 always closely fits the conveyor belt 204, maintaining a stable cleaning effect. The bottom ends of the plurality of springs 504 are fixedly connected to the top of the movable frame 402. The plurality of threaded rods 503 all penetrate the top of the movable frame 402. The plurality of nuts 505 are all in contact with the inner surface of the top of the movable frame 402. The downward pressure of the plate brush 502 can be effectively controlled through the plurality of nuts 505, thereby maintaining a certain force to effectively clean the conveyor belt 204 and reducing scratches on the conveyor belt 204.

[0046] As Figures 1 - 12As shown in the figure, an outer brush mechanism 6 is installed at a position below the reciprocating mechanism 4 near the inner brush mechanism 5. The outer brush mechanism 6 includes two second rotating shafts 601 rotatably connected to the center of the movable frame 402. Second sprockets 602 are fixedly connected to the front and rear ends of the outer walls of the two second rotating shafts 601. Second chains 603 are installed between every two second sprockets 602. A plurality of third rotating shafts 604 are rotatably connected between the two second chains 603. Brush rollers 605 are fixedly installed on the outer walls of the plurality of third rotating shafts 604. Gears 606 are fixedly connected to the front ends of the outer walls of the plurality of third rotating shafts 604. An installation frame 607 is fixedly connected to the inner surface of the front end of the movable frame 402. A rack 608 is fixedly connected to the installation frame 607. A third motor 609 is fixedly installed on one side of the front end of the movable frame 402. When the conveying mesh belt 204 is to be roughly cleaned, the third motor 609 is started. The rotation of the output shaft drives the connected second rotating shaft 601 to rotate, thereby driving the two connected second sprockets 602 to rotate, and then driving the second chain 603 to drive, so as to drive a plurality of brush rollers 605 to drive. Since the brush rollers 605 rotate, the gears 606 on the third rotating shafts 604 thereof are engaged with the rack 608 to realize rotation, thereby driving the brush rollers 605 to rotate, so as to clean the outer wall of the conveying mesh belt 204, and brush off the residual minced meat on the conveying mesh belt 204. When the roots of the brush rollers 605 are stuck with the minced meat brushed off, when passing through a plurality of brush rods 407, the brush rollers 605 will be deformed briefly. When the transmission of the brush rollers 605 is squeezed by a certain amplitude, it will briefly exert force to throw out and return to its original state, thereby ejecting the minced meat stuck to its roots, preventing the stuck minced meat from affecting the cleaning strength, and greatly improving the cleaning effect. In the combined state, a plurality of gears 606 are engaged with the rack 608, and the rear end of the output shaft of the third motor 609 is fixedly connected to the front end of one of the second rotating shafts 601. When precise cleaning is required, in cooperation with the reciprocating mechanism 4, through a series of mechanical movement modes of reciprocating movement, self-rotation and transmission, the cleaning effect on the conveying mesh belt 204 is greatly improved.

[0047] The working principle of this embodiment is as follows. The staff places the meat blocks on the conveying mesh belt 204, starts the first motor 205, and drives the connected first rotating shaft 201 to rotate through the rotation of the output shaft, thereby driving the two connected first sprockets 202 to rotate. The remaining first sprockets 202 cooperate to drive the two first chains 203 to rotate, thereby driving the conveying mesh belt 204 to rotate, so as to realize the conveying of the meat blocks.

[0048] During the process of conveying the meat chunks, that is, during the coarse cleaning, the rinsing mechanism 3 does not work. The conveying mesh belt 204 drives and touches the plate brush 502. At this time, the plate brush 502 is buffered by a plurality of springs 504, automatically adjusting the downward pressure of the plate brush 502 to clean the inner wall of the conveying mesh belt 204. At the same time, the third motor 609 is started, and the output shaft rotates to drive the connected second rotating shaft 601 to rotate, thereby driving the two connected second sprockets 602 to rotate, and then driving the second chain 603 to drive, so as to drive a plurality of rotary brushes 605 to drive. Since the rotary brush 605 is in the process of driving, the gear 606 on its third rotating shaft 604 meshes with the rack 608 to realize rotation, thereby driving the rotary brush 605 to rotate, so as to clean the outer wall of the conveying mesh belt 204, and brush off the residual minced meat on the conveying mesh belt 204. When the root of the rotary brush 605 catches the minced meat brushed off, when passing through a plurality of brush rods 407, the rotary brush 605 will be deformed briefly. When the drive of the rotary brush 605 is squeezed by a certain amplitude, it will briefly exert force and swing out to restore its original state, thereby ejecting the minced meat caught by its root and falling into the feeding funnel 13. During the coarse cleaning process, it does not affect the normal conveying of the meat chunks and can reduce the influence brought by the residual minced meat;

[0049] After the meat chunks are conveyed, that is, during the precision cleaning, the outer brush mechanism 6 is also in the starting state. The water pump 310 is started, and the water pump 310 extracts the external water source and conveys it to the first connecting pipe 308 through the second connecting pipe 311, and then conveys it into the two groups of water pipes 301. One group of water pipes 301 first sprays and rinses the conveying mesh belt 204 through a plurality of nozzles 302. At the same time, the relatively close cylinder 307 is started, and the piston is used to push the connected first connecting pipe 308, thereby pushing the two Z-shaped shafts 303 on its inner wall, and then driving the two Z-shaped shafts 303 to rotate, so as to rotate the group of water pipes 301 close to it, and realize the rotary spraying and rinsing of the conveying mesh belt 204, which can wash away the blood or minced meat existing in the gaps of the conveying mesh belt 204. At the same time, the second motor 404 is started, and the output shaft rotates to drive the turntable 405 to rotate, thereby driving the connecting rod 406 to rotate, and then driving the movable frame 402 to slide on the two slide rails 401, thereby driving the inner brush mechanism 5 and the outer brush mechanism 6 to move back and forth. Since the conveying mesh belt 204 is also in driving, a two-way mechanical friction is formed, which can effectively remove the blood clots or minced meat adhered in the gaps and grooves of the conveying mesh belt 204 to realize precision cleaning. When passing through the other group of water pipes 301, it is rinsed in the same way through a plurality of nozzles 302 to wash away the sewage remaining after washing, and finally all are collected through the feeding funnel 13.

[0050] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
