Description

Technical Field

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

[0002] The conveying device for quick-frozen food processing refers to a type of automated mechanical equipment used to continuously convey raw materials, semi-finished products or finished products during the production process of quick-frozen food. Its core function is to achieve efficient, hygienic and stable transmission of food in a low-temperature environment (usually -30°C to -40°C), while maintaining product integrity and freezing process requirements. It can adapt to the processing needs of different forms of food such as dumplings, glutinous rice balls, and prefabricated dishes. This device needs to meet food-grade hygiene standards, and has characteristics such as low-temperature resistance, anti-sticking, and easy cleaning. It usually operates in linkage with equipment such as quick-freezing tunnels and packaging machines, and is a key hub equipment for the continuous operation of the quick-freezing production line.

[0003] After quick-freezing processing, quick-frozen food needs to be transported to the packing area through a conveying device to complete the final processing steps. During the conveying process, powder is usually sprinkled on the conveyor belt regularly to prevent the quick-frozen food from slightly melting due to temperature difference and sticking together. This not only improves the appearance of the quick-frozen food production, but also can improve the conveying efficiency. However, most of the existing conveying devices use conveyor belts sleeved on conveying rollers. Although the powder sprinkled each time can coat the quick-frozen food with powder, since the conveyor belt is a cyclic drive, when it reaches the bottom position during each drive, the flour on its surface will fall off. If there is a device for recycling flour, it needs to be re-fed and used, and the operation is relatively cumbersome; and the cleaning mechanism designed on the existing conveying device is relatively simple, only simply brushing the surface of the conveyor belt. When thorough cleaning is required, the cleaning time needs to be increased, which greatly reduces the cleaning efficiency. Summary of the Invention

[0006] Further, the support mechanism includes a support frame, a material collection ring frame is fixedly connected to the top of the support frame, an outer guide ring frame is fixedly connected to the outer side of the top of the material collection ring frame, an inner guide ring frame is fixedly connected to the inner side of the top of the material collection ring frame, a slag discharge groove is provided between one side of the top of the outer guide ring frame and the material collection ring frame, a drain pipe is provided between the rear end of the top of the outer guide ring frame and the material collection ring frame, a feed inlet is provided at the rear end of the top of the outer guide ring frame, and a discharge outlet is provided at the front end of the top of the outer guide ring frame.

[0007] Through the above technical solution, the residues scraped off from the surface of the conveying mechanism fall into the material collection ring frame through the slag discharge groove. At the same time, the sewage for cleaning the surface of the conveying mechanism flows into the material collection ring frame through the drain pipe and is finally discharged uniformly. The outer guide ring frame and the inner guide ring frame are mainly used for limiting the sliding of the conveying mechanism and also for supporting each part. The device can feed materials through the feed inlet position, be conveyed by the conveying mechanism to the discharge outlet, which is convenient for the transfer of frozen food and thus convenient for subsequent packaging and processing.

[0008] Further, the conveying mechanism includes a plurality of outer pulleys installed in the outer guide ring frame, a plurality of inner pulleys are installed in the inner guide ring frame, a conveying disc is provided between the outer guide ring frame and the inner guide ring frame, an internal gear ring is fixedly connected to the inner wall top end of the conveying disc, and a first motor is installed at the bottom of the inner guide ring frame, and a gear is fixedly connected to the outer wall of the output shaft of the first motor.

[0009] Through the above technical solution, when conveying frozen food, start the first motor, drive the gear to rotate by the rotation of the output shaft, thereby driving the meshing internal gear ring to rotate, and then driving the conveying disc to rotate, realizing the automatic conveying of frozen food with high automation efficiency.

[0010] Further, a plurality of the outer pulleys are all slidably connected to the outer wall of the conveying disc, a plurality of the inner pulleys are slidably connected to the bottom end of the inner wall of the conveying disc, and the gear meshes with the internal gear ring.

[0011] Through the above technical solution, during the rotation of the conveying disc, it rolls with a plurality of outer pulleys and a plurality of inner pulleys, which is beneficial to the balance of the conveying disc and makes the conveying disc more stable when conveying frozen food.

[0012] Further, the powder sprinkling mechanism includes an annular bracket fixedly connected between the tops of the outer guiding ring frame and the inner guiding ring frame. A fixed cylinder is fixedly connected to the top of the annular bracket. A powder bin is fixedly connected to the top of the fixed cylinder. A rotating shaft is installed at the center of the powder bin. A spiral feeding knife is fixedly connected to the center of the outer wall of the rotating shaft. A first material distributing ring is arranged at the bottom of the spiral feeding knife. A second material distributing ring is arranged at the bottom of the first material distributing ring. Two third material distributing rings are arranged at the bottom of the second material distributing ring. A baffle plate is arranged at the bottom of the two third material distributing rings. A plurality of fixing rods are fixedly connected between the first material distributing ring, the second material distributing ring and the two third material distributing rings and the fixed cylinder. The bottom end of the rotating shaft is fixedly connected with a turntable. An eccentric shaft is fixedly connected to the bottom of the turntable. A connecting frame is fixedly connected to the bottom of the eccentric shaft. A sprinkling plate is fixedly connected to the outside of the connecting frame. A second motor is fixedly installed at the center of the top of the powder bin.

[0013] Through the above technical solution, before the device conveys the frozen food, it is necessary to sprinkle powder on the conveying tray to prevent sticking. Start the second motor, drive the rotating shaft to rotate through the rotation of the output shaft, and then drive the spiral feeding knife to rotate, so as to orderly discharge the flour in the powder bin downward, so that the flour first falls onto the first material distributing ring, and then passes through the second material distributing ring and the two third material distributing rings to realize the material distribution of the flour, so that the flour is dispersed onto the baffle plate and the sprinkling plate. While the rotating shaft rotates, it drives the baffle plate to rotate, so as to throw the flour into the sprinkling plate, realizing that the fed flour is evenly dispersed in the sprinkling plate. The baffle plate can not only prevent the flour from falling onto the top of the turntable, but also disperse the flour, making the sprinkling plate disperse the flour more evenly. While the rotating shaft rotates, it drives the turntable to rotate, so that the eccentric shaft rotates eccentrically, and then drives the sprinkling plate to rotate eccentrically, so as to evenly disperse the flour in the sprinkling plate onto the top of the conveying tray, and further make the coating of the frozen food more uniform, greatly reducing the occurrence of sticking phenomenon and improving the conveying efficiency of the frozen food.

[0014] Further, the rotating shaft is rotationally connected to the top of the powder bin and the first material distributing ring. The spiral feeding knife is located at the inner bottom end of the powder bin. The baffle plate is fixedly connected to the bottom end of the outer wall of the rotating shaft. The sprinkling plate is slidably connected to the annular bracket. The bottom end of the output shaft of the second motor is fixedly connected to the top end of the rotating shaft.

[0015] Through the above technical solution, when the sprinkling plate rotates eccentrically, it slides on the annular bracket, which can provide the stability of the sprinkling plate during rotation, and the maximum distance of the eccentric movement of the sprinkling plate has little contact area with the annular bracket, preventing the flour in the sprinkling plate from falling into the annular bracket.

[0016] Further, the tiling mechanism includes a first fixing frame fixedly connected between the tops of the outer guiding ring frame and the inner guiding ring frame. Limiting holes are formed on both sides of the first fixing frame. Two first limiting rods penetrate through the top of the first fixing frame. First springs are fixedly connected to the tops of the two first limiting rods. A connecting plate is fixedly connected between the tops of the two first springs. Second limiting rods penetrate through both ends of the top of the connecting plate. The inner bottom ends of the two first limiting rods are rotatably connected to connecting shafts. A flat material plate is rotatably connected between the two connecting shafts. A plurality of material dividing teeth are fixedly connected to the bottom of the flat material plate. A scraping plate is fixedly connected to the top of the flat material plate. A rotating rod is rotatably connected to the center of the connecting plate. A threaded groove is provided at the bottom end of the outer wall of the rotating rod. The other end of one of the connecting shafts is fixedly connected to a limiting disc. Two triangular grooves are formed on the limiting disc. A fixing plate is fixedly connected to one side of the first fixing frame. Two third limiting rods penetrate through the top of the fixing plate. A triangular block is fixedly connected between the tops of the two third limiting rods. Second springs are fixedly connected to the bottom of the triangular block on the outer sides of the corresponding third limiting rods respectively. A pulling block is fixedly connected between the bottoms of the two third limiting rods.

[0017] Through the above technical solution, after the conveying tray conveys the frozen food, the flour on its surface is unevenly adhered, and the powder spreading mechanism only spreads on the adhered flour, and the overall state is uneven. At this time, the conveying tray contacts the flat material plate through rotation, thereby contacting a plurality of material dividing teeth. Under the elastic force of the two first springs, the flat material plate has a downward pressure, so that the flour will pass through the gaps between the plurality of material dividing teeth, so that the thick flour on the upper surface of the conveying tray is transferred to the thin area, thereby evenly tiling the flour on the surface of the conveying tray, preventing the flour from always getting stuck on both sides of the conveying tray, making the contact between the frozen food and the flour more uniform, and there is no need to collect and reuse the remaining flour, greatly improving the conveying quality of the frozen food.

[0018] Further, the bottom ends of the two second limiting rods are respectively fixedly connected to the top ends of the corresponding first limiting rods. One ends of the two connecting shafts are respectively slidably connected to the corresponding limiting holes. One side of the flat material plate is close to the inner side of the slag discharge groove. The rotating rod is threadedly connected to the first fixing frame through the threaded groove. The bottoms of the two second springs are fixedly connected to the fixing plate. The triangular block fits with the corresponding triangular groove. A positioning ring is fixedly connected to the center of the outer wall of the rotating rod.

[0019] Through the above technical solution, after the frozen food is conveyed and the conveying tray needs to be cleaned, it is necessary to switch the leveling plate and rotate the rotating rod. Under the action of the thread groove, the connecting plate is driven to move upward, thereby driving the two first springs and the connected first limiting rods to move upward, and then driving the two connecting shafts and the connected leveling plate and scraping plate to move upward. After the elastic force released by the two second springs, the leveling plate can maintain a certain distance from the conveying tray. In order to ensure that during the 180-degree rotation of the leveling plate, the scraping plate will not touch the conveying tray, preventing inconvenient rotation and at the same time preventing scratching of the conveying tray. When moving to a certain height, pull down the pull block, thereby driving the triangular block to separate from the limiting disc, and then rotate the limiting disc by 180 degrees, thereby driving the leveling plate and the scraping plate to rotate by 180 degrees to achieve the switching. At this time, release the pulling force on the pull block. Under the action of the two second springs, drive the triangular block to fit into the corresponding triangular groove in the limiting disc, and then rotate the rotating rod to drive the scraping plate to move downward. When the positioning ring contacts the top of the connecting plate and under the action of the two first springs, the scraping plate just contacts the surface of the conveying tray. When the conveying tray rotates, the residues on its surface can be scraped off. After most of the residues are scraped off by the scraping plate and accumulate at the front end of the scraping plate, the staff can push them into the slag discharge groove and finally fall into the material collection ring frame. The residues remaining on the surface that are difficult to clean are finally cleaned by the flushing mechanism. Through segmented cleaning, the cleaning efficiency is greatly improved. At the same time, this paving mechanism can realize the arbitrary switching of the two functions, has strong functionality, is beneficial to the conveying of frozen food, and is convenient for cleaning the flour residues.

[0020] Further, the flushing mechanism includes a second fixing frame fixedly connected between the tops of the outer guiding ring frame and the inner guiding ring frame. The center of the top of the second fixing frame is fixedly installed with a cylinder. The bottom end of the piston of the cylinder is fixedly connected with a movable plate. The bottom of the movable plate is fixedly connected with a plurality of third springs. The bottoms of the plurality of third springs are fixedly connected with a movable frame. The tops of the plurality of movable frames are respectively fixedly connected with fourth limiting rods near the third springs. One side of the bottom of the movable frame is fixedly connected with a water baffle. A rotary brush is installed at the center of the bottom of the movable frame. A third motor is fixedly installed at the rear end of the movable frame. The other side of the bottom of the movable frame is fixedly connected with a spray pipe. A plurality of spray heads are fixedly connected to the bottom end of the outer wall of the spray pipe. A water pump is fixedly installed at the rear end of the top of the second fixing frame. A connecting pipe is fixedly connected between the water pump and the spray pipe.

[0021] Through the above technical solution, after most of the residues on the surface of the conveying disc are cleaned, when the remaining stubborn residues need to be cleaned, the cylinder is started, and the movable plate is pushed by the piston, thereby pushing multiple third springs and movable frames, thereby driving the movable frame to move downward a certain distance, so that the water baffle and the roller brush are just in contact with the surface of the conveying disc, and the water pump is started to draw water from the outside and transport it to the nozzle through the connecting pipe, and finally the surface of the conveying disc is flushed through multiple nozzles. The waste water after flushing is blocked by the water baffle and finally discharged into the receiving ring frame through the nearby drain pipe. At the same time, the third motor is started, and the roller brush is driven to rotate by the output shaft to brush off the stubborn residues on the surface of the conveying disc, and transported to the receiving ring frame together with the flushing water, thereby achieving precision cleaning of the conveying disc.

[0022] Furthermore, the plurality of fourth limit rods all penetrate the movable plate and the second fixed frame, the front end of the third motor output shaft is fixedly connected to the rear end of the roller brush, the rear end of the water baffle is close to the inner end of the drain pipe, and the plurality of fourth limit rods are beneficial to the stability of the movable frame when it is raised and lowered.

[0023] Through the above technical solution, the sewage flushed by the conveying plate and the residue brushed off are transported to the collecting ring frame through the drainage pipe, so as to realize rapid discharge.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention is designed with a spreading mechanism, which can spread the uneven flour on the conveying disk evenly, and can switch the flat plate and the scraper plate back and forth at will, so that most of the residues on the conveying disk can be scraped off.

An internal gear ring 204 is fixedly connected to the top end of the inner wall of the conveying disc 203. A first motor 205 is installed at the bottom of the inner guiding ring frame 104. A gear 206 is fixedly connected to the outer wall of the output shaft of the first motor 205. When conveying frozen food, the first motor 205 is started, and the gear 206 is driven to rotate by the rotation of the output shaft, thereby driving the meshing internal gear ring 204 to rotate, and then driving the conveying disc 203 to rotate, realizing the automatic conveying of frozen food with high automation efficiency.

While the rotating shaft 304 rotates, it drives the material blocking plate 309 to rotate, so as to throw the flour into the sprinkling plate 314, realizing that the fed flour is evenly dispersed in the sprinkling plate 314. The material blocking plate 309 can not only prevent the flour from falling onto the top of the turntable 311, but also disperse the flour, making the sprinkling plate 314 disperse the flour more evenly. While the rotating shaft 304 rotates, it drives the turntable 311 to rotate, so that the eccentric shaft 312 rotates eccentrically, and then drives the sprinkling plate 314 to rotate eccentrically, so as to evenly disperse the flour in the sprinkling plate 314 on the top of the conveying plate 203, and then coat the frozen food with flour more evenly, greatly reducing the occurrence of sticking phenomenon and improving the conveying efficiency of the frozen food.

After the frozen food is conveyed, when the conveying disk 203 needs to be cleaned, it is necessary to switch the flat material plate 408 and rotate the rotating rod 411.Under the action of the thread groove 412, the connecting plate 405 is driven to move upward, thereby driving the two first springs 404 and the connected first limiting rod 403 to move upward, thereby driving the two connecting shafts 407 and the connected flat material plate 408 and scraping plate 410 to move upward. After the elastic force released by the two second springs 418, the flat material plate 408 can maintain a certain distance from the conveying disc 203. In order to ensure that the scraping plate 410 does not touch the conveying disc 203 during the 180-degree rotation of the flat material plate 408, preventing inconvenient rotation and at the same time preventing scratching of the conveying disc 203. When moving to a certain height, the pull block 419 is pulled downward, thereby driving the triangular block 417 to separate from the limiting disc 413, and then the limiting disc 413 is rotated 180 degrees, thereby driving the flat material plate 408 and the scraping plate 410 to rotate 180 degrees to achieve switching. At this time, the pulling force on the pull block 419 is released. Under the action of the two second springs 418, the triangular block 417 is driven to fit into the corresponding triangular groove 414 in the limiting disc 413. Then the rotating rod 411 is rotated to drive the scraping plate 410 to move downward. When the positioning ring 4111 contacts the top of the connecting plate 405 and under the action of the two first springs 404, the scraping plate 410 just contacts the surface of the conveying disc 203. When the conveying disc 203 rotates, the residues on its surface can be scraped off. After most of the residues are scraped off by the scraping plate 410, they accumulate at the front end of the scraping plate 410. The staff can push them into the slag discharge groove 105 and finally drop into the material receiving ring frame 102. The remaining residues on the surface that are difficult to clean are finally cleaned by the flushing mechanism 5. Through segmented cleaning, the cleaning efficiency is greatly improved. At the same time, the paving mechanism 4 can realize the random switching of the two functions, with strong functionality, which is beneficial to the conveying of frozen food and convenient for the cleaning of flour residues.

[0032] As Figures 1-14As shown, a flushing mechanism 5 is installed at the rear end of the top of the support mechanism 1. The flushing mechanism 5 includes a second fixing frame 501 fixedly connected between the tops of the outer guiding ring frame 103 and the inner guiding ring frame 104. A cylinder 502 is fixedly installed at the center of the top of the second fixing frame 501. The bottom end of the piston of the cylinder 502 is fixedly connected with a movable plate 503. A plurality of third springs 504 are fixedly connected to the bottom of the movable plate 503. A movable frame 505 is fixedly connected between the bottoms of the plurality of third springs 504. Fourth limiting rods 506 are fixedly connected to the tops of the plurality of movable frames 505 respectively near the positions of the third springs 504. A water baffle 507 is fixedly connected to one side of the bottom of the movable frame 505. A rotary brush 508 is installed at the center of the bottom of the movable frame 505. A third motor 509 is fixedly installed at the rear end of the movable frame 505. A spray pipe 510 is fixedly connected to the other side of the bottom of the movable frame 505. A plurality of spray nozzles 511 are fixedly connected to the bottom end of the outer wall of the spray pipe 510. A water pump 512 is fixedly installed at the rear end of the top of the second fixing frame 501. A connecting pipe 513 is fixedly connected between the water pump 512 and the spray pipe 510. After most of the residues on the surface of the conveying disc 203 are cleaned, when it is necessary to clean the remaining stubborn residues, the cylinder 502 is started. The movable plate 503 is pushed by the piston, thereby pushing the plurality of third springs 504 and the movable frame 505, and driving the movable frame 505 to move downward by a certain distance, so that the water baffle 507 and the rotary brush 508 just contact the surface of the conveying disc 203. The water pump 512 is started to extract external water source and convey it into the spray pipe 510 through the connecting pipe 513. Finally, the surface of the conveying disc 203 is flushed through the plurality of spray nozzles 511. The flushed waste water is blocked by the water baffle 507 and finally discharged into the material receiving ring frame 102 through the nearby drain pipe 106. At the same time, the third motor 509 is started, and the rotary brush 508 is driven to rotate by the rotation of the output shaft, so as to brush off the stubborn residues on the surface of the conveying disc 203 and convey them into the material receiving ring frame 102 together with the flushing water, so as to realize the precision cleaning of the conveying disc 203. The plurality of fourth limiting rods 506 all penetrate through the movable plate 503 and the second fixing frame 501. The front end of the output shaft of the third motor 509 is fixedly connected with the rear end of the rotary brush 508. The rear end of the water baffle 507 is close to the inner end of the drain pipe 106. The plurality of fourth limiting rods 506 are beneficial to the stability of the movable frame 505 during lifting and lowering. The sewage flushed on the conveying disc 203 and the residues brushed off are all conveyed into the material receiving ring frame 102 through the drain pipe 106 to realize rapid discharging.

[0033] The working principle of this embodiment is as follows. Before conveying the frozen food, the first motor 205 is started first. The rotation of the output shaft drives the gear 206 to rotate, which in turn drives the engaged internal gear ring 204 to rotate, thereby driving the conveying disk 203 to rotate. Then, the second motor 315 is started. The rotation of the output shaft drives the rotating shaft 304 to rotate, which in turn drives the spiral feeding knife 305 to rotate, so as to orderly discharge the flour in the flour bin 303 downward. The flour first falls onto the first material distribution ring 306, and then passes through the second material distribution ring 307 and two third material distribution rings 308 to achieve the distribution of the flour, so that the flour is dispersed onto the baffle plate 309 and the spreading plate 314. While the rotating shaft 304 rotates, it drives the baffle plate 309 to rotate, so as to throw the flour into the spreading plate 314, realizing that the fed flour is evenly dispersed in the spreading plate 314. While the rotating shaft 304 rotates, it drives the turntable 311 to rotate, so that the eccentric shaft 312 rotates eccentrically, thereby driving the spreading plate 314 to rotate eccentrically, so as to evenly distribute the flour in the spreading plate 314 on the top of the conveying disk 203, realizing the powder spreading on the conveying disk 203; Workers can feed materials through the feeding port 107. Under the action of the conveying mechanism 2, the frozen food is conveyed to the discharging port 108 to realize the transfer of materials; After the first batch of frozen food is conveyed, the flour on its surface is unevenly adhered, and the powder spreading mechanism 3 only spreads on the adhered flour, and the overall state is uneven. At this time, the conveying disk 203 contacts the flat material plate 408 through rotation, thereby contacting multiple material distribution teeth 409. Under the elastic force of the two first springs 404, the flat material plate 408 has a downward pressure, so that the flour will pass through the gaps between the multiple material distribution teeth 409, so that the thick flour on the upper surface of the conveying disk 203 is transferred to the thin area, so as to evenly spread the flour on the surface of the conveying disk 203, realizing the even spreading of the flour on the surface of the conveying disk 203, and making the next batch of frozen food coated with flour more evenly; After the quick-frozen food is conveyed and needs to be cleaned, the staff rotates the rotating rod 411. Under the action of the thread groove 412, the connecting plate 405 is driven to move upward, thereby driving the two first springs 404 and the connected first limiting rod 403 to move upward, and then driving the two connecting shafts 407 and the connected flat material plate 408 and scraping plate 410 to move upward. After the elastic force released by the two second springs 418, the flat material plate 408 can maintain a certain distance from the conveying tray 203. Then, the pull block 419 is pulled downward, thereby driving the triangular block 417 to separate from the limiting disc 413. Then, the limiting disc 413 is rotated 180 degrees, thereby driving the flat material plate 408 and the scraping plate 410 to rotate 180 degrees to achieve switching. At this time, the pulling force on the pull block 419 is released. Under the action of the two second springs 418, the triangular block 417 is driven to fit with the corresponding triangular groove 414 in the limiting disc 413. Then, the rotating rod 411 is rotated to drive the scraping plate 410 to move downward. When the positioning ring 4111 contacts the top of the connecting plate 405 and under the action of the two first springs 404, the scraping plate 410 just contacts the surface of the conveying tray 203. When the conveying tray 203 rotates, most of the residues on its surface can be scraped off. After most of the residues are scraped off by the scraping plate 410, they accumulate at the front end of the scraping plate 410. The staff can push them into the slag discharge groove 105 and finally drop into the material receiving ring frame 102. When cleaning the remaining stubborn residues, the air cylinder 502 is started. The piston is used to push the movable plate 503, thereby pushing a plurality of third springs 504 and the movable frame 505, and then driving the movable frame 505 to move downward a certain distance, so that the water baffle 507 and the rotary brush 508 just contact the surface of the conveying tray 203. The water pump 512 is started to extract the external water source and convey it to the spray pipe 510 through the connecting pipe 513. Finally, the surface of the conveying tray 203 is rinsed through a plurality of nozzles 511. The waste water after rinsing is blocked by the water baffle 507 and finally discharged into the material receiving ring frame 102 through the nearby drain pipe 106. At the same time, the third motor 509 is started, and the rotary brush 508 is driven to rotate through the output shaft, so as to brush off the stubborn residues on the surface of the conveying tray 203 and convey them to the material receiving ring frame 102 together with the rinsing water, thereby realizing the precision cleaning of the conveying tray 203.

[0034] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
