[0018] Put the materials to be quick-frozen into the lower hopper troughs of each group in order from small to large in volume;

[0019] The material to be quick-frozen falls into the quick-freezing limit mechanism below through the lower hopper slot. When the gap on the quick-freezing limit mechanism is larger than the diameter of the material to be quick-frozen, the material to be quick-frozen will fall directly until it falls on a set of quick-freezing limit mechanisms corresponding to its own volume.

[0022] After the quick freezing work is completed, the conveyor belt body is started to transport the materials to be quick frozen out of the quick freezing equipment to obtain finished quick frozen materials.

[0023] The beneficial effects of the present invention are:

[0024] 1. Place materials of different volumes in the order of small to large in each group of quick-freezing limiter mechanism from bottom to top according to the above method, so as to improve the compatibility of the conveyor line. Then, they enter the cavity of the quick-freezing equipment along with the conveyor belt body. Since the quick-freezing limiter mechanism is a hollow structure and there are gaps between each group of anti-leakage strips, the cold air can directly act on the materials to be quick-frozen from any height and any direction, so that the cold air can flow freely. There is no need to turn over the materials, and all-round quick freezing can be achieved, thereby improving the air intake efficiency, and improving the compatibility while also improving the freezing effect.

[0025] 2. After the quick-frozen material falls, it is transported by the conveyor belt body to the bottom of the adjacent group of vertical pipes, and then the one-way valve controls a group of slightly larger quick-frozen materials to fall. Then repeat the above actions until there is quick-frozen material on each group of quick-freezing limit mechanisms. In this way, the automatic classification, automatic unloading, and automatic stratification of different volumes can be achieved, and the function of simultaneously transmitting and quick-freezing multiple layers of quick-frozen materials can be met without manual classification and placement, thereby shortening the quick-freezing preparation time and reducing the number of quick-freezing times, thereby improving the quick-freezing efficiency and meeting the needs of rapid transportation.

[0026] 3. Inject condensed liquid into the central ball, each group of horizontal tubes, crescent tubes and side baffles. When the material to be quick-frozen enters the cavity of the quick-freezing equipment, the condensed liquid absorbs cold air and applies the cold air to the junction between it and the material to be quick-frozen. When the material to be quick-frozen is a special-shaped material with a groove, the central ball will fit exactly with the groove. No matter what the shape of the material to be quick-frozen is, the material to be quick-frozen can be completely in contact with the cold source. At the same time, the condensed liquid is used to ensure that the junction between the material to be quick-frozen and the material can still contact the cold source, thereby avoiding dead corners in all directions.

[0027] 4. The two groups of rotating rods on both sides of the same group of material feeding slots rotate in opposite directions. When the quick-frozen materials are blocked at the junction of the straight plate and the oblique plate due to orientation problems, the rotating turntable and the material-digging teeth are used to continuously stir the quick-frozen materials until they can enter the material feeding slots, thereby improving the smoothness of the loading work.

DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The embodiment of the present invention provides a high-speed transport line for a quick freezing device, for example, Figure 1 and Figure 2 As shown, it includes a conveyor belt body 100, and a central through groove 110 is provided on the central axis of the conveyor belt body 100 in the length direction.

[0043] Several groups of material conveying units 200 are arranged in the middle through groove 110 at equal intervals along the length direction of the conveyor belt body 100. The material conveying units 200 are used to convey the material to be quick-frozen.

[0044] A loading unit 300 is disposed just above the input end of the middle through slot 110 . The loading unit 300 is used to transport materials into each group of material transport units 200 .

[0045] For example, Figure 3 and Figure 4 As shown, the material conveying unit 200 includes two groups of connecting rods 201, which are symmetrically arranged on the inner walls of both sides of the central through slot 110, and a plurality of groups of material trays 210 are arranged at equal intervals between the two groups of connecting rods 201. A horn-shaped material tray 211 is provided at the center of the material tray 210, and the inner diameter of the top of the material tray 211 is larger than the inner diameter of the bottom. A spiral air guide groove 220 is provided on the inner wall of the material tray 211, and the spiral air guide groove 220 is a spiral structure.

[0046] Exemplarily, a limiting component is provided at the bottom of the lower hopper trough 211, and the limiting component includes a plurality of groups of quick-freezing limiting mechanisms 230 arranged at equal intervals in the vertical direction, and the diameters of the plurality of groups of quick-freezing limiting mechanisms 230 decrease from top to bottom. Two adjacent groups of quick-freezing limiting mechanisms 230 are connected to each other through a plurality of groups of anti-leakage strips 240, and the plurality of groups of anti-leakage strips 240 on the same horizontal line are distributed in a ring array.

[0047] For example, Figure 5 As shown, the quick-freezing limit mechanism 230 includes an upper limit ring 231 and a lower limit ring 232. The diameter of the lower limit ring 232 is smaller than that of the upper limit ring 231, and the central axis of the lower limit ring 232 coincides with the central axis of the upper limit ring 231. A plurality of side stop tubes 233 are distributed in an annular array between the upper limit ring 231 and the lower limit ring 232. A central ball 234 is provided on the central axis of the lower limit ring 232. A plurality of transverse tubes 235 are distributed in an annular array around the central ball 234. A crescent tube 236 is hingedly connected to one end of the transverse tube 235 close to the central axis of the lower limit ring 232. The side cross section of the crescent tube 236 is a fan-shaped structure. A spring is connected to the other end of the crescent tube 236, and the other end of the spring is mounted on the central ball 234.

[0048] Specifically, the distance between two adjacent groups of transverse tubes 235 on each group of the quick-freezing limiting mechanism 230 is smaller than the distance between two adjacent groups of transverse tubes 235 on the upper group of quick-freezing limiting mechanism 230 .

[0049] First, condensed liquid is injected into the central ball 234, each group of horizontal tubes 235, the crescent tube 236 and the side baffle tube 233. When the material to be quick-frozen enters the cavity of the quick-freezing equipment, the condensed liquid absorbs the cold air and applies the cold air to the junction between it and the material to be quick-frozen. During quick freezing, since one section of the conveyor belt body 100 is located in the cavity of the quick freezing equipment, it is only necessary to place the materials to be quick frozen in each group of discharge trays 210 in the order of small first and large later. When the small-volume materials to be quick frozen fall first, since the distance between the two adjacent groups of transverse tubes 235 on each group of quick freezing limiting mechanisms 230 is smaller than the distance between the two adjacent groups of transverse tubes 235 on the upper group of quick freezing limiting mechanisms 230, they will fall directly from the gap between the transverse tubes 235 of the upper quick freezing limiting mechanisms 230 to the bottom group of quick freezing limiting mechanisms 230, and be guided by the transverse tubes 235 to the center ball 234 at the center. When the materials to be quick frozen are special-shaped materials with grooves (such as vegetables and fruits with holes at the bottom), the center ball 234 will be exactly located in the holes. No matter what the shape of the materials to be quick frozen is, they can be fully in contact with the cold source to avoid dead corners. Then, materials of different volumes are placed in each group of quick-freezing limiting mechanisms 230 from bottom to top in order from small to large according to the above method.

[0050] For example, Figure 6 As shown, the conveyor belt body 100 enters the cavity of the quick freezing equipment. Since the quick freezing limit mechanism 230 is a hollow structure composed of an upper limit ring 231, a lower limit ring 232 and a plurality of side stop tubes 233, the cold air can directly act on the material to be quick frozen from any height and any direction, so that the cold air can flow freely and all-round quick freezing can be achieved without turning the material.

[0051] For example, Figure 7 , Figure 8 and Fig. 9 As shown, the loading unit 300 includes an inclined unloading plate 310, one end of which is lower in height and is located directly above the middle through slot 110, and the other end of the unloading plate 310 is connected to a vertically arranged loading box 311, and a loading port 312 is provided on the top of the loading box 311. A plurality of groups of material delivery slots 340 are arranged at equal intervals on the inner wall at the bottom of the unloading plate 310, and the number of the material delivery slots 340 is the same as the number of the unloading trays 210 on the same group of material conveying units 200, and the spacing between two adjacent groups of the material delivery slots 340 is the same as the spacing between two adjacent groups of unloading hopper slots 211.

[0052] Exemplarily, a feeding plate 370 is provided in the feeding channel 340, and a plurality of groups of feeding holes 371 having the same number as the quick-freezing limiting mechanism 230 are arranged at equal intervals along the length direction of the feeding plate 370, and the spacing between two adjacent groups of the feeding holes 371 is the same as the spacing between two adjacent groups of material conveying units 200. The inner diameters of the plurality of groups of the feeding holes 371 increase in equal increments from one side close to the upper material box 311 to the other side. The bottom of each group of the feeding holes 371 is connected to a group of vertical pipes, and a one-way valve is provided at the bottom of the vertical pipes.

[0053] Exemplarily, two groups of straight through plates 350 are symmetrically arranged at the two side edges of the top of each group of the material feeding troughs 340, and the straight through plates 350 are connected to an inclined oblique through plate 351 at a port near one end of the loading box 311, and the other end of each group of the oblique through plates 351 is connected to the oblique through plate 351 on the adjacent group of material feeding troughs 340.

[0054] Exemplarily, a material shifting mechanism 360 is provided at the junction of the oblique plate 351 and the straight plate 350. The two groups of material shifting mechanisms 360 on the same group of the material feeding slots 340 rotate in relative directions. The unloading plate 310 is provided with a power transmission component 320, and each group of the material shifting mechanisms 360 is transmission-connected to the output end of the power transmission component 320.

[0055] Exemplarily, a group of vertical rods 333 are installed at the bottom of each group of the feeding plates 370, and the bottom of the vertical rods 333 extends to the bottom of the unloading plate 310. A bottom box 330 is provided at the bottom of the unloading plate 310, and a vibration motor 331 is installed in the bottom box 330 along the horizontal direction. The output end of the vibration motor 331 is transmission-connected to a vibration frame 332, and the bottom of each group of the vertical rods 333 is installed on the vibration frame 332.

[0056] For example, Fig.10 As shown, the material shifting mechanism 360 includes a vertically arranged rotating rod 361, on which a plurality of groups of rotating disks 362 are arranged at equal intervals in the vertical direction, and on the side walls of each group of rotating disks 362, a plurality of groups of material shifting teeth 363 are distributed in a circular array.

[0057] The material to be quick-frozen is poured into the loading box 311 as a whole, and moves toward the side of the material feeding channel 340 as the unloading plate 310 tilts. Since the height of the unloading plate 310 is lower than that of the loading box 311, the material to be quick-frozen avoids the problem of stacking each other after entering the unloading plate 310. Then, it is guided by the inclined plate 351 and the movement of each group of rotating disks 362 and material-shifting teeth 363 to quickly come to the material feeding plate 370, and falls into the vertical pipes below each group of unloading holes 371 according to its own volume, and is controlled by the one-way valve at the bottom so that only one group of the same volume of material to be quick-frozen falls each time.

[0058] After the quick-frozen material falls, it is transported by the conveyor belt body 100 to the bottom of the adjacent group of vertical pipes, and then the one-way valve controls a group of slightly larger quick-frozen materials to fall. Then repeat the above actions until there is quick-frozen material on each group of quick-freezing limiter mechanisms 230. In this way, the automatic classification, automatic unloading, and automatic stratification of different volumes can be achieved, and the function of simultaneously transmitting and quick-freezing multiple layers of quick-frozen materials can be met without manual classification and placement, thereby shortening the quick-freezing preparation time and reducing the number of quick-freezing times, thereby improving the quick-freezing efficiency and meeting the needs of rapid transportation.

[0059] The vibration motor 331 drives the vibration frame 332 to vibrate, and then the vibration frame 332 transfers kinetic energy to each group of vertical rods 333, and then each group of vertical rods 333 drives a corresponding group of feeding plates 370 to vibrate. When the material to be quick-frozen comes onto the feeding plate 370, the vibration force generated by the feeding plate 370 can move quickly, avoiding the batch of material to be quick-frozen from being blocked in the feeding channel 340, thereby improving the smoothness of the feeding work.

[0060] The above embodiments have the following beneficial effects:

[0061] 1. Place materials of different volumes in the order of small to large in each group of quick-freezing limiting mechanisms 230 from bottom to top according to the above method, so as to improve the compatibility of the conveyor line. Then, they enter the cavity of the quick-freezing equipment along with the conveyor belt body 100. Since the quick-freezing limiting mechanism 230 is a hollow structure and there are gaps between each group of anti-leakage strips 240, the cold air can directly act on the materials to be quick-frozen from any height and any direction, so that the cold air can flow freely. There is no need to turn over the materials, and all-round quick freezing can be achieved, thereby improving the air intake efficiency, and improving the compatibility while also improving the freezing effect.

[0062] 2. After the quick-frozen material falls, it is transported by the conveyor belt body 100 to the bottom of the adjacent group of vertical pipes, and then the one-way valve controls a group of slightly larger materials to be quick-frozen to fall. Then repeat the above actions until there are materials to be quick-frozen on each group of quick-freezing limiter mechanisms 230. In this way, the automatic classification, automatic unloading, and automatic stratification of different volumes can be achieved, and the function of simultaneously transmitting and quick-freezing multiple layers of materials to be quick-frozen can be met, without manual classification and placement, thereby shortening the quick-freezing preparation time and reducing the number of quick-freezing times, thereby improving the quick-freezing efficiency and meeting the needs of rapid transportation.

[0063] 3. Condensed liquid is injected into the central ball 234, each group of transverse tubes 235, the crescent tube 236 and the side baffle tube 233. When the material to be quick-frozen enters the cavity of the quick-freezing equipment, the condensed liquid absorbs cold air and applies the cold air to the junction between it and the material to be quick-frozen. When the material to be quick-frozen is a special-shaped material with a groove, the central ball 234 will fit exactly with the groove. No matter what the shape of the material to be quick-frozen is, the material to be quick-frozen can be completely in contact with the cold source. At the same time, the condensed liquid is used to ensure that the junction between the material to be quick-frozen and the material can still contact the cold source, thereby avoiding dead corners in all directions.

[0064] 4. The two groups of rotating rods 361 on both sides of the same group of material feeding grooves 340 rotate in opposite directions. When the material to be quick-frozen is blocked at the junction of the straight plate 350 and the oblique plate 351 due to orientation problems, the rotating turntable 362 and the material-moving teeth 363 are used to continuously move the material to be quick-frozen until it can enter the material feeding grooves 340, thereby improving the smoothness of the feeding work.

[0065] 5. When the cold air is blown down from above the material to be quick-frozen and passes through the lower hopper groove 211, since the lower hopper groove 211 is a trumpet-shaped structure and the spiral air guide groove 220 is spirally distributed on its inner wall, the cold air will move in a spiral shape in the lower hopper groove 211, gradually gather, and then blow to the material to be quick-frozen below. This improves the cold air blowing effect and the freezing efficiency.

[0066] Based on the above-mentioned high-speed transport line for quick freezing device, the embodiment of the present invention further proposes a working method of the transport line. Exemplarily, the working method includes:

[0067] Pour the material to be quick-frozen into the loading box as a whole, and move it toward the side of the feeding channel as the unloading plate tilts;

[0068] The batch of materials to be quick-frozen are evenly divided and placed on each group of feeding plates. The vibration motor is started to drive each group of feeding plates to vibrate, so that the materials to be quick-frozen are quickly moved to the lower feeding plate away from the side of the feeding box;

[0069] When the volume of the material to be quick-frozen is larger than the diameter of a group of feeding holes, the material to be quick-frozen will pass quickly in the vibration until it encounters a group of feeding holes with the same diameter as its own volume, at which time the material to be quick-frozen enters the group of vertical pipes;

[0070] The one-way valves on each group of vertical pipes are started at the same time, and the discharge holes with different apertures simultaneously discharge the materials to be quick-frozen to the corresponding groups of discharge trays below. Each group of one-way valves discharges the same quantity each time, so that materials of different volumes to be quick-frozen can be discharged in batches at the same time.

[0071] The material to be quick-frozen falls through the lower hopper slot to the quick-freezing limit mechanism below. When the distance between two adjacent sets of horizontal tubes is greater than the diameter of the material to be quick-frozen, the material to be quick-frozen will fall directly until it falls on a set of quick-freezing limit mechanisms corresponding to its own volume.

[0072] After the same set of limiting components has been placed through all the aperture discharge holes and each corresponding set of quick-freezing limiting mechanisms has a set of materials to be quick-frozen of corresponding volumes, the conveyor belt body is started to transport each set of materials to be quick-frozen to the quick-freezing equipment for quick freezing;

[0073] Cold air blows from all heights and directions into the quick-freezing limit mechanism of the hollow structure and acts on each group of materials to be quick-frozen;

[0074] After the quick freezing work is completed, the conveyor belt body is started to transport the materials to be quick frozen out of the quick freezing equipment to obtain finished quick frozen materials.

[0075] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
