Technical Field
[0001] This application relates to the field of food processing equipment technology, and in particular to a weighing device for a quick-frozen dumpling production line. Background Technology
[0002] Frozen dumplings are made by quickly freezing pre-made dumplings for refrigeration and consumption at any time. Large-scale factory production of frozen dumplings often uses dumpling forming machines. Machine-made dumplings must be handled gently and shaped by hand to maintain their good shape. During shaping, any substandard dumplings, such as those that are flat, missing corners, cracked, or irregularly shaped, should be removed. Excessive force or improper handling during shaping, such as overly tight arrangement and compression, can cause well-shaped dumplings to flatten, become deformed and not plump, or even leak juice, stick together, or crack. Shaped dumplings should be promptly sent to a freezing room for freezing. Once frozen, the dumplings can be bagged. To ensure consistent weight in each bag, the dumplings must be weighed before bagging. This process requires accurate measurement; the net weight must not be lower than national measurement standards and regulations. Measuring instruments must be calibrated frequently during operation. The mainstream equipment used for weighing frozen dumplings is the multi-head weighing machine.
[0003] A multi-head weighing machine is a high-efficiency weighing device based on multi-sensor collaborative computing. Frozen dumplings are fed into the weighing machine's feeding channel by an elevator, and then evenly distributed into a linear vibrating plate by the main vibrating plate below the feeding channel. When the number of frozen dumplings in the feeding plate is insufficient, a photoelectric detector sends a signal to the control system, triggering the elevator to replenish the material. The linear vibrating plate can then use amplitude control to transport the frozen dumplings to multiple buffer hoppers as needed (generally, a multi-head weighing machine has 8-24 buffer hoppers), with each buffer hopper corresponding to a weighing hopper. The opening and closing of the buffer hoppers is controlled by a stepper motor to ensure that frozen dumplings flow into the weighing hopper as needed. Each weighing hopper is equipped with a high-precision weighing sensor at its bottom to weigh the frozen dumplings falling into it. When the packaging machine issues a signal to allow unloading, the CPU drives the stepper motor to open the gate of the selected weighing hopper, and the frozen dumplings fall into the collection hopper via a chute or directly into the packaging machine. The weighing hoppers not involved in the combination retain material for the next calculation.
[0004] To prevent frozen dumplings from deforming during transportation and packaging, they are frozen before packaging. However, frozen dumplings not only become harder but also significantly more brittle. During freezing, water forms ice crystals that pierce the gluten network and fiber structure in the dumpling skin, creating tiny holes and making the skin brittle. There is a certain height between the unloading end of the conveyor and the conical main vibrating plate. When the frozen dumplings unloaded from the conveyor fall directly onto the main vibrating plate along the feeding channel, they collide directly with the plate under gravity. For brittle frozen dumplings, this collision can easily damage the edges, affecting the yield rate. Utility Model Content
[0005] This application provides a weighing device for a quick-frozen dumpling production line, which can buffer the quick-frozen dumplings as they fall onto the main vibrating plate, thereby reducing the breakage rate of the quick-frozen dumplings.
[0006] The above-mentioned objective of this application is achieved through the following technical solution:
[0007] A weighing device for a quick-frozen dumpling production line includes a weighing machine body. A cylindrical feeding channel is provided directly above the main vibrating plate of the weighing machine body. An erecting platform is provided on the outside of the feeding channel. Multiple support frames are provided on the outside of the erecting platform along its circumference. The erecting platform is connected to the weighing machine body through the multiple support frames.
[0008] The inside of the feeding channel is equipped with a buffer liner, which can buffer the frozen dumplings as they fall along the feeding channel, reducing the kinetic energy of the frozen dumplings when they collide with the main vibrating plate.
[0009] There is a gap between the lower port of the feeding channel and the main vibrating plate.
[0010] Furthermore, the buffer liner is specifically a spiral plate, the diameter of which is equal to the inner diameter of the feeding channel, and the spiral plate and the inner wall of the feeding channel are welded together.
[0011] Furthermore, the feeding channel is inserted at the center of the erected platform and the two are rotatably connected.
[0012] Furthermore, the erected platform is equipped with a power component, which can drive the feeding channel to rotate around its own axis.
[0013] Furthermore, the power assembly includes a gear ring, which is fixedly sleeved on the outside of the feeding channel and located on the upper side of the erecting platform. A gear is meshed on one side of the gear ring, and the gear is fixedly connected to the output shaft of a motor fixedly installed on the erecting platform. A shaft bracket is rotatably connected to the output shaft of the motor, and the lower side of the shaft bracket is fixedly connected to the erecting platform.
[0014] Furthermore, the upper port of the feeding channel is designed with a wide opening.
[0015] Furthermore, multiple arc-shaped plastic strips are fixedly installed along the circumference of the lower end of the feeding channel.
[0016] In summary, this application includes at least one of the following beneficial technical effects:
[0017] This application adds a buffer liner inside the traditional feeding channel. When frozen dumplings fall into the feeding channel from the top of the feeding machine, the buffer liner inside the feeding channel will consume some of the kinetic energy carried by the frozen dumplings. In this way, the risk of the frozen dumplings being damaged by collision with the main vibrating plate when they are discharged from the feeding channel can be effectively reduced, and the yield of frozen dumpling products can also be improved.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0025] In frozen dumpling production lines, the elevator 9 that transports frozen dumplings to the weighing machine often uses a scraper conveyor. The scraper conveyor is inclined above the weighing machine's loading channel 3 and the ground, creating a distance (approximately 0.5-1 meter) between the upper end of the scraper conveyor (its discharge end) and the conical main vibrating plate 2 responsible for distributing the frozen dumplings. To ensure that the frozen dumplings discharged from the scraper conveyor fall vertically onto the main vibrating plate 2, a cylindrical hollow loading channel 3 is installed directly above the main vibrating plate 2 to guide and constrain the fall of the frozen dumplings. Multi-head weighing machines are suitable for products beyond just frozen dumplings; they can also be used for candies, seeds, nuts, and other foods. Since most products rarely experience damage during production, equipment manufacturers do not make special designs for the interior of the loading channel 3. However, in the production of frozen dumplings, the overall brittleness of frozen dumplings increases significantly after freezing. If they are dropped vertically onto the conical main vibrating plate 2 under gravity along the feeding channel 3, they are easily damaged, especially the edges of the frozen dumplings, which are often the most severely damaged. To solve this problem, this application provides the following specific solution.
[0026] like Figures 1-4 As shown, a weighing device for a quick-frozen dumpling production line disclosed in this application includes a weighing machine body 1. A cylindrical feeding channel 3 is provided directly above the main vibrating plate 2 of the weighing machine body 1. An erecting platform 4 is provided on the outside of the feeding channel 3. Multiple support frames 5 are provided on the outside of the erecting platform 4 along its circumference. The erecting platform 4 is connected to the weighing machine body 1 through the multiple support frames 5.
[0027] The inside of the feeding channel 3 is equipped with a buffer liner, which can buffer the frozen dumplings as they fall along the feeding channel 3, reducing the kinetic energy of the frozen dumplings when they collide with the main vibrating plate 2.
[0028] There is a gap between the lower port of the feeding channel 3 and the main vibrating plate 2.
[0029] In the above embodiments, this application adds a buffer liner inside the traditional feeding channel 3. When the frozen dumplings fall from the top of the feeding machine into the feeding channel 3, the kinetic energy carried by the frozen dumplings will be consumed by the buffer liner inside the feeding channel 3. In this way, the risk of the frozen dumplings being damaged by collision with the main vibrating plate 2 when they are discharged from the feeding channel 3 can be effectively reduced, and the yield of the frozen dumpling products can also be improved.
[0030] Furthermore, such as Figure 3 As shown, the buffer liner is specifically a spiral plate 6. The diameter of the spiral plate 6 is equal to the inner diameter of the feeding channel 3. The spiral plate 6 and the inner wall of the feeding channel 3 are welded together.
[0031] In the above embodiments, the spiral plate 6 of this application can form a continuously spiraling slide channel inside the feeding channel 3. After the frozen dumplings fall into the feeding channel 3, they will fall in a spiral shape along the spiral trajectory of the spiral edge under the forced guidance of the spiral plate 6. Compared with the time for frozen dumplings to fall vertically without obstruction, the time can be extended by about 0.1 to 0.3 seconds. The formula for impact force is F = mΔv / t, where Δv represents the difference between the initial and final velocities of the frozen dumpling, t represents the duration of motion, and m is the mass of the object. Regardless of the method, the initial velocity of the frozen dumpling after being unloaded from the elevator 9 is 0. Therefore, the value of the velocity change mainly depends on its final velocity. The spiral plate 6 of this application not only prolongs the motion time of the frozen dumpling, but also reduces its final velocity through continuous friction with the frozen dumpling. This makes the technical solution of this application, compared with the prior art, reduce the value of Δv and increase the value of t. In addition, with the mass of the frozen dumpling remaining unchanged, according to the impact force formula, the spiral plate 6 set in the feeding channel 3 of this application can significantly reduce the impact force when the frozen dumpling is discharged. Correspondingly, the risk of the frozen dumpling being damaged by collision with the main vibrating plate 2 will be greatly reduced. This can effectively ensure the overall integrity of the frozen dumpling when it falls from a height onto the main vibrating plate 2, and improve the product yield of the enterprise's frozen dumplings.
[0032] Furthermore, the feeding channel 3 is inserted at the center of the erected platform 4 and the two are rotatably connected.
[0033] In the above embodiments, when the frozen dumplings slide out along the lower end of the spiral plate 6, their landing point is located on one of the inclined surfaces of the conical main vibrating plate 2. If the spiral plate 6 does not move, only a portion of the buffer hopper and weighing hopper in the main body 1 of the weighing machine will be used. In this application, the connection between the feeding channel 3 and the erecting platform 4 is set as a rotating connection. In this way, the feeding channel 3 can rotate on the erecting platform 4 to make the discharged frozen dumplings slide evenly along the conical main vibrating plate 2 to different buffer hoppers, so as to ensure that all components of the multi-head weighing machine can be effectively utilized.
[0034] Furthermore, such as Figure 1 and Figure 3 As shown, the erected platform 4 is equipped with a power component 7, which can drive the feeding channel 3 to rotate around its own axis.
[0035] In the above embodiments, the power component 7 installed on the erecting platform 4 can ensure the continuity of production in the quick-frozen dumpling production line, and enable the feeding channel 3 to rotate automatically.
[0036] Furthermore, such as Figure 3 As shown, the power assembly 7 includes a gear ring 71, which is fixedly sleeved on the outside of the feeding channel 3 and located on the upper side of the erecting platform 4. A gear 72 is meshed on one side of the gear ring 71. The gear 72 is fixedly connected to the output shaft of the motor 73, which is fixedly installed on the erecting platform 4. A shaft bracket 74 is rotatably connected to the output shaft of the motor 73, and the lower side of the shaft bracket 74 is fixedly connected to the erecting platform 4.
[0037] In the above embodiments, the feeding channel 3 and the erecting platform 4 can achieve a low-resistance rotational connection through bearing components. The gear ring 71 fixedly installed on the outer side of the feeding channel 3 is in a meshing state with the gear 72 connected to the output shaft of the motor 73 (the state of the two is similar to two meshing bevel teeth). After the weighing device of this application is started, the motor 73 can also run synchronously. In this way, the motor 73 can drive the feeding channel 3 to rotate continuously around its own axis at the center of the erecting platform 4 through the cooperation of the gear ring 71 and the gear 72. During the rotation of the feeding channel 3, the lower end of the spiral plate 6 in the feeding channel 3 will also rotate circumferentially along the main vibrating plate 2. In this way, the quick-frozen dumplings discharged by the spiral plate 6 can still be evenly distributed to the buffer hoppers at different positions through the main vibrating plate 2. In actual production, if it is necessary to control the speed of the motor 73, a reducer can be added to the power output end of the motor 73.
[0038] Furthermore, such as Figures 1-4 As shown, the upper port of the feeding channel 3 is designed with a wide opening.
[0039] In the above embodiments, the upper port of the feeding channel 3 is designed as a wide opening (similar to a trumpet mouth), so that the feeding channel 3 can cover as many frozen dumplings as possible that slide down from the top of the elevator 9.
[0040] Furthermore, such as Figures 2-4 As shown, multiple arc-shaped plastic strips 8 are fixedly installed along the circumference of the lower end of the feeding channel 3.
[0041] In the above embodiments, the multiple arc-shaped plastic strips 8 provided at the lower end of the feeding channel 3 have a certain elasticity. When the frozen dumplings slide out along the main vibrating plate 2, the arc-shaped plastic strips 8 can limit the discharge angle of the frozen dumplings, preventing the frozen dumplings from sliding out at too large an angle and causing them to pass over the buffer hopper.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
