Description

Technical Field

[0001] This invention relates to the field of feed processing machinery technology, and in particular to a conveying device for the production of animal oil products for feed. Background Technology

[0002] In feed production processes, animal oils (such as lard and tallow) stored in cold storage are usually in the form of hard, large solid blocks. Existing transportation and processing methods mostly involve directly transporting large solid animal oil products to a melting furnace or melting tank via conventional conveyor belts or manual handling. The oil is then heated at high temperatures and melted into a liquid before being pumped out to the next production process.

[0003] However, this traditional method of "directly melting large blocks of oil in the furnace" has obvious drawbacks: due to the small surface area and extremely low central thermal conductivity of large solid oil blocks, the overall melting takes a very long time, which not only seriously slows down the production pace but also causes huge heat energy consumption; moreover, prolonged high-temperature boiling can easily cause secondary oxidation and rancidity of the outer layer of oil, affecting the quality and palatability of the finished feed.

[0004] To improve the above shortcomings, a separate cutting device is set up to cut animal oil products into small pieces. However, due to the strong low-temperature solidification characteristics of animal oil products, the trace amount of liquid oil on the cut surface will quickly refreeze after the slit is cut and the slit passes through the shavings. This causes the cut pieces to stick together again, rendering the cutting action meaningless. Moreover, setting up a separate cutting device not only affects the conveying efficiency of animal oil products, but also increases the footprint of the overall production equipment.

[0005] Therefore, it is necessary to design a conveying device for the production of animal oil products for feed to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a conveying device for the production of animal oil products for feed. This invention can achieve efficient cutting of animal oil into blocks before it enters the furnace during the conveying process, and avoid the problems of slippage and re-sticking after cutting during the block conveying process.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A conveying device for producing animal oil products for feed includes two sets of conveying modules, which are arranged vertically to carry and convey animal oil products. Each conveying module includes two fixed frames, and a conveying roller is rotatably connected between the two fixed frames. The two conveying rollers are connected by a conveyor belt. A first motor is installed on the lower fixed frame, and the output shaft of the first motor is fixedly connected to the shaft of one of the conveying rollers. Multiple partitions are spaced apart on the outer surface of the upper conveyor belt. The animal oil products are located between two adjacent partitions and are forcibly conveyed to a cutting end through the partitions. The upper and lower sets of conveying modules are synchronized by a transmission assembly. A cutting assembly is located at the output end of the conveying module and is used to cut the conveyed animal oil products.

[0008] In some possible implementations, the mounting frame is equipped with a hydraulic cylinder for vertically adjusting the spacing between the upper and lower sets of conveyor belts.

[0009] In some possible implementations, an elastic tensioning wheel mechanism is also included, which includes a rectangular box, a first spring disposed within the rectangular box, and a slider connected to the first spring. The slider is slidably connected within the rectangular box and is used to automatically compensate for changes in the transmission path and maintain tension when the hydraulic cylinder adjusts the spacing.

[0010] In some possible implementations, the cutting assembly includes a fixing block, a fixing ring, a mounting ring, a mounting base, and a rectangular frame. The fixing ring is fixedly connected to two fixing brackets and to the fixing block. The mounting base is mounted on the fixing ring. The rectangular frame is fixedly connected to the inner wall of the mounting ring. A second motor is mounted on the mounting base, and a gear is connected to the output end of the second motor. Multiple toothed ridges that mesh with the gear are fixedly connected to the outer wall of the mounting ring. An annular groove is provided on the inner wall of the fixing ring, and a rotating ring is adapted to fit in the annular groove. A connecting ring is fixedly connected to the inner wall of the rotating ring, and the connecting ring is fixedly connected to the mounting ring. Copper wires are arranged in a crisscross pattern inside the rectangular frame. The copper wires are energized and heated to perform thermomelting cutting of animal oil products.

[0011] In some possible implementations, the inner wall of the rectangular frame is provided with a plurality of rectangular slots, and each rectangular slot is provided with an adaptive yielding component. The end of the copper wire is mounted on the corresponding adaptive yielding component. The adaptive yielding component includes a fixed plate, a slide rail, a sliding plate slidably connected to the slide rail, and a second spring. The slide rail is mounted on the inner wall of the rectangular slot, and the two ends of the second spring are fixedly connected to the fixed plate and the sliding plate. When the hardness of the animal oil product is greater than the preset value, the copper wire is pressed, causing the sliding plate to slide along the slide rail and compressing the second spring to produce a yielding. Combined with the local heat melting caused by the heating of the copper wire and the elastic restoring force of the second spring, the copper wire is embedded and cut into the animal oil product.

[0012] In some possible implementations, the output side of the cutting assembly is provided with a receiving assembly, which includes a rectangular plate fixedly connected to the inner wall of the fixing ring by a connecting rod, and the rectangular plate has a plurality of rectangular holes arranged in an array to match the cutting size; Animal oil products cut by the cutting component enter the rectangular hole with the propulsion force for physical isolation to prevent sticking, and then demold from the rectangular hole as subsequent animal oil products continue to be pushed forward.

[0013] In some possible implementations, short rods are fixedly connected to both the slider and the two conveyor roller shafts, and the three short rods are connected by a transmission assembly, which includes three sprockets connected by a chain drive.

[0014] The present invention has the following beneficial effects: 1. Compared with existing technologies, the anti-slip forced propulsion design: through the cooperation of the upper and lower conveyor modules, the baffles set on the outer surface of the upper conveyor belt can push the animal oil products into the cutting component like a bulldozer blade, avoiding the slippage and stagnation problem caused by insufficient friction of a single-layer conveyor belt. 2. Compared with existing technologies, an adaptive retraction component is introduced within the cutting rectangle. When an extremely hard block of refrigerated oil comes into contact with the heating copper wire, the wire will not "cut hard." Instead, it will retract under pressure and compress the second spring to store energy. As the heating copper wire partially melts the contact surface, the resistance decreases, and the elastic restoring force of the second spring slowly presses the copper wire into the grease. This flexible mechanism perfectly avoids wire breakage and extends the equipment's lifespan. 3. Compared with the existing technology, a receiving component with rectangular holes is seamlessly connected behind the cutting component. The small pieces of grease that are cut are instantly squeezed into the grid for physical isolation and cannot re-contact. Then, the continuous squeezing force of the grease block behind pushes the grease block in front out of the grid and falls naturally into the carburetor, preventing secondary adhesion. 4. Compared with the existing technology, the elastic tensioning wheel mechanism with a first spring ensures that the transmission chain remains taut when the device uses a hydraulic cylinder to adjust the gap between the upper and lower conveyor belts (to accommodate oil blocks of different thicknesses), thus ensuring the absolute synchronous operation of the upper and lower conveyor modules.

Detailed Implementation

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] Reference Figures 1-6A conveying device for producing animal oil products for feed includes two sets of conveying modules, which are arranged vertically to carry and convey animal oil products. The two sets of conveying modules are arranged parallel to each other, with the upper and lower conveyor belts touching and clamping the animal oil products. Stable clamping and conveying of materials is achieved by synchronous operation of the upper and lower modules. It can be adapted to solid animal oil raw materials of different thicknesses. The conveying module 1 includes two fixed frames 101, and a conveying roller is rotatably connected between the two fixed frames 101. The two conveying rollers are connected by a conveyor belt 102. The conveyor belt 102 is made of wear-resistant and high-temperature resistant rubber, which is suitable for conveying low-temperature solid oils and hot-melt cutting conditions. The lower fixed frame 101 is equipped with... There is a first motor 103, the output shaft of the first motor 103 is fixedly connected to one of the conveyor roller shafts, and multiple partitions 104 are spaced apart on the outer surface of the upper conveyor belt 102. The partitions 104 are fixed perpendicular to the surface of the conveyor belt 102. The partitions 104 are of uniform thickness and are evenly spaced. The partitions 104 are made of rigid plastic material. The bottom is vulcanized and fixed to the conveyor belt. The edges are rounded and chamfered to avoid scratching or squeezing and damaging solid animal oil products. The animal oil products are located between two adjacent partitions 104 and are forcibly conveyed to the cutting end through the partitions 104. The rigid thrust is formed by the end face of the partition against the back of the oil block, which eliminates the slippage and stagnation problems caused by insufficient friction of the single-layer conveyor belt. A cutting assembly, located at the output end of the conveying module 1, is used to cut the conveyed animal oil products. The cutting assembly 2 includes a fixing block 201, a fixing ring 202, a mounting ring 207, a mounting base 203, and a rectangular frame 208. The fixing ring 202 is fixedly connected to two fixing brackets 101 and the fixing block 201. The mounting base 203 is mounted on the fixing ring 202. The rectangular frame 208 has a square hollow frame structure, and its outer edge is welded and fixedly connected to the inner wall of the mounting ring 207. A second motor 204 is mounted on the mounting base 203. The second motor 204 is a speed-regulating rotary motor that can adjust the rotational cutting speed of the rectangular frame to adapt to animal oil products of different hardness. The output end of the machine 204 is connected to a gear 205. The outer wall of the mounting ring 207 is fixedly connected to multiple toothed ridges 206 that mesh with the gear 205. A rotating ring 211 that can rotate freely in the circumferential direction is fitted into the annular groove of the fixed ring 202. The rotating ring 211 is in clearance fit with the annular groove. A connecting ring 210 is fixedly connected to the inner wall of the rotating ring 211. The connecting ring 210 is fixedly connected to the mounting ring 207. Copper wires 209 are arranged crosswise in the rectangular frame 208. The copper wires 209 are heated by electricity to perform hot melt cutting of animal oil products. The copper wires are made of high conductivity and high temperature resistant copper. After being energized, they heat up rapidly and rely on local high temperature to melt the oil contact surface, reduce cutting resistance, and reduce the problems of wire breakage and material crushing caused by hard shearing.

[0020] In some embodiments of this disclosure, the fixed frame 101 is provided with four hydraulic cylinders 105. The top of the piston rod of the four hydraulic cylinders 105 is connected to the bottom surface of the fixed frame 101 of the upper conveying module, which is used to vertically lift and adjust the clamping gap between the upper and lower sets of conveyor belts 102. The clamping gap can be flexibly adjusted according to the different thicknesses of animal oil products taken out of the cold storage, and it is suitable for various specifications of raw materials.

[0021] In some embodiments of this disclosure, an elastic tensioning wheel mechanism is also included. The elastic tensioning wheel mechanism 3 includes a rectangular box 302, a first spring 303 disposed within the rectangular box 302, and a slider 304 connected to the first spring 303. The slider 304 is slidably connected within the rectangular box 302 and is used to automatically compensate for changes in the transmission path and maintain tension when the hydraulic cylinder 105 adjusts the spacing. The rectangular box 302 is fixedly mounted on the lower fixed frame by a bracket and is used to automatically compensate for changes in the length of the transmission path and continuously maintain the chain tension when the hydraulic cylinder 105 adjusts the spacing between the upper and lower conveyor belts and changes the center distance of the transmission wheels, so as to prevent the chain from loosening and skipping teeth. Short rods are fixedly connected to the slider 304 and the two conveyor roller shafts. The three short rods are connected by a transmission assembly 301. The transmission assembly 301 includes three sprockets and the three sprockets are connected by a chain drive.

[0022] In some embodiments of this disclosure, the inner wall of the rectangular frame 208 is provided with a plurality of rectangular slots, and each rectangular slot is provided with an adaptive yielding component. The end of the copper wire 209 is installed on the corresponding adaptive yielding component. The adaptive yielding component 5 includes a fixed plate 504, a slide rail 502, a sliding plate 501 slidably connected to the slide rail 502, and a second spring 503. The slide rail 502 is installed on the inner wall of the rectangular slot, and the two ends of the second spring 503 are fixedly connected to the fixed plate 504 and the sliding plate 501. When a cold-cold solid animal oil product with a hardness greater than a preset value comes into contact with the copper wire 209, the copper wire 209 is pressed, causing the sliding plate 501 to slide horizontally backward along the slide rail 502 and compressing the second spring 503 to generate a yielding force. Simultaneously, the local heat melting and softening of the contact surface caused by the heating of the copper wire 209 reduces the resistance. Then, relying on the elastic restoring force of the second spring 503, it rebounds forward, allowing the copper wire 209 to smoothly embed and completely cut the animal oil product. The elastic yielding buffers the instantaneous impact force of the hard oil block on the copper wire, avoiding the direct hard pulling of the hard frozen grease that would cause the copper wire to break, thus extending the service life of the cutting consumables. At the same time, the elastic rebound ensures that the copper wire completely cuts into the material, and the cut surface is flat and without any material residue.

[0023] In some embodiments of this disclosure, the output side of the cutting component 2 is provided with a receiving component 4. The receiving component 4 includes a rectangular plate 403 fixedly connected to the inner wall of the fixing ring 202 by a connecting rod 401. The rectangular plate 403 has a plurality of rectangular holes 402 arranged in an array to match the cutting size. The animal oil products cut by the cutting component 2 enter the rectangular hole 402 under the propulsion force for physical isolation to prevent sticking, and then demold from the rectangular hole 402 as the subsequent animal oil products continue to be pushed in.

[0024] The functional principle of this invention can be explained through the following operation: During operation, based on the thickness of the animal oil products taken from the cold storage, the hydraulic cylinder 105 on the fixed frame 101 is activated to vertically adjust the height of the upper conveying module 1. During this lifting and lowering process, the first spring 303 in the elastic tension wheel mechanism 3 pushes the slider 304, automatically compensating for path changes in the transmission assembly 301 composed of a short rod, sprocket, and chain, ensuring that the chain is always in a reasonable tension state.

[0025] The first motor 103 is started, and its output shaft drives the lower conveyor roller to rotate. The power is transmitted in reverse to the upper conveyor roller through the transmission component 301. At this time, the upper and lower conveyor belts 102 move synchronously towards the output end. The block animal oil product is placed on the lower conveyor belt, and the partition 104 of the upper conveyor belt is inserted into the rear end face of the animal oil product, forming a rigid clamping state of upper pressure and lower support, and forced push from the rear, so as to push the solid oil block stably and without slipping towards the cutting component.

[0026] When solid animal oil products are forcibly pushed to the cutting assembly by the lower conveyor belt and the partition 104 of the upper conveyor belt, the first step is to perform a "yielding embedding" action: because the oil blocks that have just come out of the warehouse are extremely hard, the front end of the material is directly pressed against the interlaced copper wires 209 in the rectangular frame 208. After being pressed, the copper wires push the sliding plate 501 backward along the slide rail 502 and compress the second spring 503 to yield and store force; at the same time, the electrically heated copper wires 209 gradually and locally melt the solid grease on the contact surface. Under the combined push of the reduced resistance and the elastic restoring force of the second spring 503, the interlaced copper wires 209 are slowly and smoothly completely embedded into the interior of the animal oil products.

[0027] After the copper wire is embedded in the animal oil product, the "rotational cutting" action is immediately performed: the second motor 204 is started, and the gear 205 at its output end drives the toothed edge 206 on the outside of the mounting ring 207 to rotate. Under the limit of the annular groove inside the fixed ring 202, the rotating ring 211 drives the connecting ring 210 and the entire rectangular frame 208 to rotate in place. At this time, the interlaced copper wire 209, which is deeply embedded in the solid oil, rotates accordingly. Using the physical shearing force generated by the electric heating and rotation, the animal oil product is cut into strips.

[0028] As the animal oil products are cut into small cubes through the copper wire 209, the continuous pushing force from the rear conveyor belt partition 104 causes the cut oil blocks to be seamlessly pushed directly into the rectangular plate 403 fixed on the back of the cutting component 2. These small oil blocks enter the corresponding rectangular holes 402 and are physically isolated by the surrounding hole walls, preventing the cut seams from being re-sealed and eliminating the secondary coagulation and re-adhesion phenomenon from the root.

[0029] As new animal oil products are continuously cut and pushed forward, the new cut pieces will push against the cut pieces in front, forcing the cut products stuck in the rectangular hole 402 to demold outward and eventually fall into the degreasing equipment below, completing the automated and efficient conveying and deblocking separation.

[0030] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
