Description

Technical Field

[0001] This invention relates to the field of industrial processing technology for rice cakes, and particularly to a belt conveyor. Background Technology

[0002] Rice cake belongs to the staple food category of grains in the industrialized food processing. With the large-scale development of the food processing industry, the mechanized continuous production of rice cake has become the mainstream of the industry. Belt conveyor equipment is an important part of the rice cake production line, used to transport the high-temperature rice cake strips that have just been formed by the extruder. Freshly extruded, high-temperature rice cake strips have a high water content, strong starch activity, and a soft, glutinous texture. When they fall directly onto the conveyor belt, they tend to adhere tightly to the belt over a large area, resulting in significant adhesion problems. At the same time, the rice cake residue and gluten remaining on the belt surface will be repeatedly heated and dried, continuously accumulating. This not only exacerbates the subsequent adhesion problem, creating a vicious cycle, but also easily breeds microorganisms and accumulates dirt, failing to meet food processing hygiene standards. Furthermore, it requires frequent shutdowns for cleaning, restricting the continuous operation of the production line. Existing technologies often use anti-stick coatings on the belt or powdering to improve adhesion. However, anti-stick coatings are prone to wear and failure under long-term high temperatures and friction, and their anti-stick effect decays rapidly. Therefore, a belt conveyor device is needed. Summary of the Invention

[0003] The purpose of this invention is to provide a belt conveyor to solve the problem of adhesion in existing belt conveyors when conveying rice cakes. This is because freshly extruded, high-temperature rice cake strips have a high water content, strong starch activity, and a soft, glutinous texture. When they fall directly onto the conveyor belt, they easily form a large area of ​​tight adhesion with the belt, resulting in a significant adhesion problem. At the same time, the rice cake residue and gluten remaining on the belt surface will be repeatedly heated and dried, continuously accumulating, which not only aggravates the subsequent adhesion phenomenon and creates a vicious cycle, but also easily breeds microorganisms and accumulates dirt, failing to meet the hygiene standards for food processing.

[0008] Preferably, the piston cylinder has a piston inside, a connecting plate is hinged to the top of the piston, the top of the connecting plate is hinged to one end of the disc, a second one-way valve is provided on one side of the piston cylinder, one end of the second one-way valve is connected to one end of the heat dissipation pipe, a first one-way valve is provided at the bottom of the piston cylinder, a water tank is provided on one side of the top of the conveyor, one end of the first one-way valve is connected to one end of the water tank, and one end of the water tank is connected to one end of the heat dissipation plate.

[0009] Preferably, one end of the cooling plate is hinged to both sides inside the conveyor, the surface of the eccentric roller is in contact with the surface of one side of the bottom end of the cooling plate, a second pulley is provided on the outer side of one end of the eccentric roller, a first pulley is provided on one end of the fixed column, the first pulley is connected to the second pulley through a synchronous belt, and a collection box is installed at the bottom end of the filter screen.

[0010] Preferably, the fan blades are provided in two sets, which are symmetrically distributed on both sides of the top of the conveyor. One set of fan blades is located inside the wind-collecting shroud, and the other set of fan blades is located on one side of the heat dissipation pipe.

[0011] Preferably, the heat sink is provided in multiple sets, and the multiple sets of heat sink are arranged at equal intervals inside the cooling plate.

[0012] Preferably, the outer sides of the first gear, the second gear, and the third gear are provided with a plurality of teeth, and the first gear, the second gear, and the third gear mesh with each other.

[0013] Preferably, the nozzle is designed to be inclined on one side of the connecting cavity, and a plurality of nozzles are provided, which are arranged at equal intervals on one side of the connecting cavity.

[0014] The belt conveyor provided by this invention has the following advantages: By setting an anti-sticking structure, and through the transmission link consisting of a fixed column, a first belt pulley, a second belt pulley, an eccentric roller, a third gear, a second gear, a first gear, a disc, a connecting plate, and a piston, the three functions of vibration powder spreading, air cooling heat dissipation, and circulating water cooling can be driven simultaneously. No additional independent drive components and electrical control systems are required, which reduces equipment energy consumption and manufacturing costs. Furthermore, by vibrating synchronously with the cooling plate, the rice flour inside is sieved and dispersed by the screening screen and then falls evenly onto the plate surface, forming a stable isolation layer on the bottom of the rice cake, which directly prevents the rice cake from directly sticking to the cooling plate. Furthermore, the rice cake is conveyed with a small vibration by a tilted cooling plate, which allows the rice cake to slide at a uniform speed without being stuck in place for a long time. With the help of multiple heat dissipation structures, the heat of the rice cake is quickly dissipated, and the surface of the rice cake is quickly cooled and shaped, which greatly reduces the activity of starch. When the pre-cooled rice cake falls onto the conveyor belt, the problem of hot soft material sticking tightly to the belt over a large area is avoided from the root, effectively eliminating quality defects such as rice cake pulling and deformation and local breakage, and significantly improving the yield of finished products. Furthermore, the directional airflow generated by the fan blades is gathered and guided by the air shroud, flowing over the surface of the heat sink inside the cooling plate, quickly carrying away the heat conducted by the plate surface. The heat dissipation water plate, which is attached to the bottom of the cooling plate, achieves secondary water cooling through a closed water circulation driven by a piston, a first one-way valve, and a second one-way valve. At the same time, the eccentric roller synchronously drives another set of fan blades to force air cooling on the outer wall of the heat dissipation pipe and pre-cool the circulating return water. The multi-stage heat dissipation works together to quickly remove the heat accumulated in the cooling plate, avoiding excessive temperature rise of the panel after long-term continuous operation. This prevents the rice cake from softening and sticking again due to high plate temperature, and ensures the cooling and shaping efficiency of the rice cake. It is suitable for continuous industrial production conditions and constructs a multi-heat exchange system of "internal air cooling + circulating water cooling + return water pre-cooling" to improve the anti-sticking effect.

[0020] When conveying the freshly extruded rice cake, the conveyor 1 is installed below the discharge end of the rice cake machine. During the conveying operation, the external power supply starts the drive motor, which drives the active rotating roller 4 to rotate. The rotating roller 4 synchronously drives the conveyor belt 3 to run in a cycle. The high-temperature rice cake strips extruded by the rice cake machine first fall onto the upper surface of the cooling plate 203. At this time, the rotating roller 4 on one side synchronously drives the fixed column 201 to rotate. The fixed column 201 drives the second belt pulley 2012 to rotate through the first belt pulley 202. The second belt pulley 2012 further drives the eccentric roller 2014 to rotate. Relying on its own eccentric structure characteristics, and in conjunction with the structure in which one end of the cooling plate 203 is hinged to the top of the conveyor frame 1, the continuous rotation of the eccentric roller 2014 can drive the cooling plate 203 to vibrate up and down at a high frequency. While the cooling plate 203 vibrates, it synchronously drives the powder box 204 on it to vibrate. The rice flour in the powder box 204, which is the same as the rice cake raw material, is vibrated and evenly passes through the screening screen 2028 and falls onto the surface of the cooling plate 203. The screening screen 2028 can screen and disperse the rice flour to prevent the powder from clumping and falling onto the plate surface, ensuring that the powder is evenly spread. After the rice flour is evenly distributed on the surface of the cooling plate 203, a layer of powder will adhere to the bottom of the falling hot rice cake, forming an isolation layer that prevents direct contact between the rice cake and the cooling plate 203 and avoids them sticking together. The cooling plate 203 is arranged at an angle, and with continuous small-amplitude vibration, the rice cake strips can slide at a uniform speed along the plate surface towards the conveyor side. Because the vibration amplitude is controllable, the rice flour will not fly everywhere, ensuring a clean working environment. At the same time, continuous vibration can increase the frequency of contact between the rice cake and the air, accelerating the cooling and shaping of the rice cake surface. When the rice cake slides to the filter screen 205 station, the filter screen 205 can sift off the excess powder on the plate surface and let it fall into the collection box below for recycling. At the same time, when the rice cake vibrates with the plate surface, the excess powder attached to the surface will also be shaken off, effectively reducing the amount of powder residue on the surface of the rice cake and ensuring the appearance and taste of the finished product. After being vibrated and cooled and having excess powder removed, the rice cake strips fall onto the working surface of the conveyor belt 3 and are conveyed forward at a uniform speed with the belt. When the eccentric roller 2014 rotates, it synchronously drives the third gear 2013 to rotate coaxially. The third gear 2013 drives the second gear 2011 through tooth meshing, and then the second gear 2011 meshes with and drives the first gear 2010, which finally drives the fan blade 2021 to rotate at high speed. The fan blades 2021 generate directional airflow, which is gathered and guided by the air shroud 2022 and sent into the internal cavity of the cooling plate 203. When the airflow flows over the surface of the heat sink 2023, it can quickly remove the heat conducted by the cooling plate 203, accelerate the cooling of the plate surface, and prevent the temperature of the cooling plate 203 from rising too high after the equipment has been operating continuously for a long time. This not only prevents the rice cake from softening and sticking due to the high temperature of the plate surface, but also ensures the cooling and shaping efficiency of the rice cake. The airflow carrying residual heat flows into the connecting cavity 207 after converging with the installation pipe 2019 and the connecting pipe 206. Finally, it is directionally sprayed out by the nozzle 208. The nozzle 208 is arranged at an inclined angle with the lower surface of the return section of the conveyor belt 3. The sprayed airflow can sweep and clean the surface of the belt. A collection box 209 is set below the conveyor belt 3. The rice noodles blown off by the airflow are blocked by the box wall and fall into the box, realizing the centralized recovery of the powder. At the same time, the residual heat airflow blown out by the nozzle 208 can also dry the surface of the belt while cleaning the powder, avoiding the belt from getting damp and accumulating powder, aggravating the risk of adhesion, and further improving the conveying stability. At the same time, the other end of the eccentric roller 2014 synchronously drives the disc 2017 to rotate. The disc 2017 drives the piston 2025 to reciprocate linearly in the piston cylinder 2018 through the connecting plate 2024, forming a closed water-cooled circulation loop driven by pure mechanical force. When piston 2025 retracts to pump water, the second one-way valve 2027 opens and the first one-way valve 2026 closes, drawing the water that has absorbed heat in the radiator plate 2020 into piston cylinder 2018. The radiator plate 2020 is fitted to the bottom surface of the cooling plate 203. The continuous flow of water inside carries away the heat conducted by the cooling plate 203, achieving secondary water cooling of the plate surface. When piston 2025 pushes forward to drain water, the second one-way valve 2027 closes and the first one-way valve 2026 opens, and the water in piston cylinder 2018 is discharged into water tank 2015 through the pipeline. The water in water tank 2015 flows back to radiator plate 2020, thus forming a continuous cycle and continuously enhancing the heat dissipation efficiency of cooling plate 203. With the coordinated arrangement of the two sets of fan blades 2021, the eccentric roller 2014 drives the other set of fan blades 2021 to operate synchronously when it rotates, which forces air cooling on the outer wall of the heat dissipation pipe 2016. During the process of circulating water flowing back through the heat dissipation pipe 2016, the airflow driven by the fan blades 2021 quickly removes the heat from the pipe wall, pre-cools the water inside the pipe, and further improves the overall heat exchange effect of the water cooling circuit. Thus, the entire set of equipment relies solely on the single conveying power of the rotating roller 4 to simultaneously drive the three functions of the cooling plate 203: vibration and powder spreading, internal air cooling and heat dissipation, and circulating water cooling. This forms a purely mechanically linked integrated anti-sticking and cooling system. When the rice cake falls onto the surface of the cooling plate 203, the evenly spread rice flour forms a physical isolation layer on the bottom of the rice cake, preventing direct adhesion between the rice cake and the plate surface. At the same time, the multiple heat dissipation structures of air cooling and water cooling quickly dissipate the heat of the rice cake, allowing the surface of the rice cake to cool and solidify rapidly, significantly reducing the activity and adhesion of starch. When the pre-cooled and shaped rice cake falls onto the surface of conveyor belt 3, the problem of adhesion caused by the large-area close contact between the hot, soft rice cake and the belt is avoided from the root. It also prevents the phenomenon of rice cake residue and glue drying and accumulating on the belt surface due to heat. This not only eliminates quality defects such as rice cake stretching and deformation and local breakage caused by adhesion, but also avoids the growth of microorganisms from residual dirt and violations of food processing hygiene standards. At the same time, it greatly reduces the frequency of machine downtime for manual cleaning, ensuring the continuous and stable operation of the production line, and finally solves the problem of rice cake sticking to conveyor belt 3 during the conveying of rice cake.
