Description

Technical Field

[0001] This utility model relates to the field of duck carcass packaging equipment, and in particular to an automatic grading and packaging production line for low-temperature and high-humidity frozen duck carcasses. Background Technology

[0002] Roast duck is a common delicacy. Before roasting, frozen duck carcasses are needed. Freezing, as the name suggests, involves operating in a low-temperature, high-humidity environment. To ensure the uniformity of the duck carcasses' size and the integrity of their appearance, a weight grading process is essential. Generally, the frozen duck carcasses are divided into four grades by weighing them. Those with a weight value greater than or equal to a certain threshold are grouped together, and those with a weight value less than that threshold are grouped together. However, previously, each duck carcass had to be weighed and graded individually using an electronic scale. This process had low automation and efficiency, and manual grading was prone to errors, further reducing the effectiveness of the grading work. Moreover, after each weighing and packing, the entire box of frozen duck carcasses needed to be sealed with tape, which was both labor-intensive and affected the appearance of the box.

[0003] Therefore, it is evident that the existing methods for grading, packing, and packaging frozen duck carcasses still have inconveniences and shortcomings, and urgently need further improvement. Creating an automated grading and packaging production line for low-temperature, high-humidity frozen duck carcasses that saves manpower, has high grading efficiency, and high grading accuracy has become a pressing goal for the industry.

The printhead of the inkjet printer is located on one side of the conveyor belt of the inkjet printer.

[0009] Furthermore, the lifting rotary conveyor includes a frame, a lifting rotary rod mounted on the frame, a cross support mounted on the top of the lifting rotary rod, and rollers mounted on the frame and around the cross support; the lifting rotary rod is driven by a servo motor and an electric cylinder.

[0010] Furthermore, a first acceleration conveyor belt is also provided between the first conveyor belt and the single weighing machine.

[0011] Furthermore, a second acceleration conveyor belt is also provided between the third conveyor belt and the electric turning and pushing device.

[0012] Furthermore, the single-animal rejection and grading device includes a pusher plate driven by a cylinder or electric cylinder, the surface of which is made of elastic nylon material; there are four single-animal rejection and grading devices.

[0013] Furthermore, the third conveyor belt has a double-layer conveyor structure, with the lower conveyor belt used to convey frozen duck carcass packaging boxes and the upper conveyor belt used to buffer or convey empty packaging boxes.

Detailed Implementation

[0034] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0035] like Figure 1 As shown in the figure, this embodiment provides an automatic grading and packaging production line for low-temperature, high-humidity frozen duck carcasses, including a first conveyor belt 1, a single-duck weighing machine 2, and a second conveyor belt 3 connected in sequence. The single-duck weighing machine 2 is in the form of a conveyor belt. Multiple single-duck rejection and grading devices 4 are spaced apart on one side of the second conveyor belt 3, and the single-duck rejection and grading devices 4 are slightly higher than the second conveyor belt 3. The number of single-duck rejection and grading devices 4 can be determined according to the weight class required for packaging. For example, if four weight classes need to be packaged, then four single-duck rejection and grading devices 4 are set. Multiple packing operation platforms 5 are vertically arranged on the other side of the second conveyor belt, each corresponding to a single-duck rejection and grading device 4; that is, one single-duck rejection and grading device 4 corresponds to one packing operation platform 5. The single-duck weighing machine 2 is used to weigh and grade the frozen duck carcasses conveyed from the first conveyor belt 1, and controls the corresponding single-duck rejection and grading device 4 to push the frozen duck carcasses on the second conveyor belt 3 to the corresponding packing operation platform 5. The single-duck weighing machine 2 can be equipped with a display screen for convenient weight display.

[0036] This is the first part of the production line, primarily responsible for grading and packing frozen duck carcasses by weight. In actual operation, frozen duck carcasses are sequentially placed onto the first conveyor belt 1. Driven forward by the first conveyor belt 1, each carcass enters a single-carcass weighing machine 2. The machine weighs and grades the carcass individually. Once a carcass is determined to belong to a specific weight class, it is activated when it reaches the corresponding single-carcass rejection and grading device 4 on the second conveyor belt 3. This device quickly pushes the carcass to the corresponding packing platform 5. At this point, personnel at the packing platform 5 quickly pack the carcass of that weight class into boxes. It should be noted that frozen duck carcasses that do not meet the weight class requirements are simply conveyed out along the second conveyor belt 3 without being graded or packaged.

[0037] The aforementioned production line also includes a third conveyor belt 6 perpendicularly connected to the packing platform 5, and a full-case weighing machine 7, a fourth conveyor belt 8, a box sealing machine 9, an inkjet printer 10, and a fifth conveyor belt 11 sequentially connected to the third conveyor belt 6; wherein, the full-case weighing machine 7, the box sealing machine 9, and the inkjet printer 10 are all in the form of conveyor belts; the full-case weighing machine 7 is used to weigh the frozen duck carcasses conveyed by the packing platform 5 and the third conveyor belt 6, and controls the inkjet printer 10 to print codes according to the weight of the full case when the frozen duck carcasses enter the inkjet printer 10 via the fourth conveyor belt 8 and the box sealing machine 9; the frozen duck carcasses after inkjet printing enter the fifth conveyor belt 11.

[0038] This is the second part of the production line. Its main function is to weigh, seal, and print weight codes on the boxes of frozen duck carcasses after packing. In actual operation, when the box is full of frozen duck carcasses of that grade at the packing platform 5, the operator pushes it onto the third conveyor belt 6. The box moves forward on the third conveyor belt 6. When the box enters the box weighing machine 7, it is weighed. After weighing, it is conveyed to the sealing machine 9 via the fourth conveyor belt 8. The sealing machine 9 can be an existing sealing machine with a conveyor function. For flat frozen duck carcasses, it seals from the top center, improving the appearance of the sealed box. After sealing, it enters the coding machine 10. The coding machine 10 prints a weight code on the box based on the weight feedback from the box weighing machine 7. The coded frozen duck carcasses are then conveyed out via the fifth conveyor belt 11, completing the entire grading and packaging process.

[0039] The conveyor belts of the first conveyor belt 1, the single weighing machine 2, the second conveyor belt 3, the full box weighing machine 7, and the inkjet printer 10 are all belt belts, while the third conveyor belt 6, the fourth conveyor belt 8, the box sealing machine 9, and the fifth conveyor belt 11 are all roller belts.

[0040] Considering the limited space, for factories with small areas, this is a preferred implementation method, combined with... Figure 1 , 2 As shown, the second part of the aforementioned production line can be configured to turn, such as by setting the third conveyor belt 6 parallel to the full-case weighing machine 7, and adding an electric turning and pushing device 12 between them; its main function is to push the frozen duck carcass packaging boxes from the third conveyor belt 6 to the full-case weighing machine 7 parallel to it. Specifically, as shown... Figure 2 As shown, the electric turning and pushing device 12 includes a first turning conveyor belt 121 and a second turning conveyor belt 122 connected to each other, both in roller form. The first turning conveyor belt 121 is located at the rear end of the third conveyor belt 6, and the second turning conveyor belt 122 is located at the front end of the full-case weighing machine 7. A turning push plate 123 is provided on the side of the first turning conveyor belt 121. The turning push plate 123 is used to laterally push the frozen duck carcass packaging boxes that enter from the third conveyor belt to the second turning conveyor belt 122. The frozen duck carcass packaging boxes are then conveyed to the full-case weighing machine 7 via the second turning conveyor belt 122. By setting up the electric turning and pushing device 12, the floor space of the equipment can be greatly reduced, making it suitable for factories of different sizes.

[0041] Cooperate Figure 1 , 3 As shown, a lifting rotary conveyor 13 is also connected between the sealing machine 9 and the inkjet printer 10. The lifting rotary conveyor 13 is used to lift and rotate the frozen duck carton packaging box by 90° before conveying it into the inkjet printer 10. Specifically, in conjunction with... Figure 3 As shown, the lifting rotary conveyor 13 includes a frame 131, a lifting rotary rod mounted on the frame 131, a cross support 132 mounted on the top of the lifting rotary rod, and rollers 133 mounted on the frame 131 and around the cross support 132. The lifting rotary rod is driven by a servo motor and an electric cylinder, which is more suitable for low-temperature and high-humidity environments. By setting up the lifting rotary conveyor 13, the longitudinally conveyed frozen duck carcass packaging boxes can be turned into a transverse shape, and the inkjet printer 10 can print on the short side of the frozen duck carcass packaging box. This allows the main information to be displayed on the long side of the frozen duck carcass packaging box, and the width of the conveyor belt in front of the inkjet printer 10 does not need to be too wide; only the width of the inkjet printer 10 and the rear conveyor belt needs to be slightly wider. This further reduces the footprint of the equipment.

[0042] To improve packaging efficiency, frozen duck carcasses can be quickly placed sequentially on the first conveyor belt 1. However, if the frozen duck carcasses are conveyed too quickly, the single-duck weighing machine 2 cannot accurately identify them one by one. As a preferred embodiment, a first acceleration conveyor belt 14 can be added between the first conveyor belt 1 and the single-duck weighing machine 2. Before two frozen duck carcasses that are close together are conveyed to the single-duck weighing machine 2, the two frozen duck carcasses can be separated by different speeds at the first acceleration conveyor belt 14, so that they enter the single-duck weighing machine 2 one by one, achieving accurate identification of each duck and improving the packaging efficiency of the entire production line.

[0043] Similarly, a second acceleration conveyor belt (not shown in the figure) is added between the third conveyor belt 6 and the electric turning and pushing device 12. This can separate two boxes of frozen duck carcasses that are close together before they enter the electric turning and pushing device 12 and the box weighing machine 7.

[0044] like Figure 1 As shown, the aforementioned single-duck rejection and grading device 4 includes a pusher plate (not shown in the top view) driven by a cylinder or electric cylinder. The top of the pusher plate can move along a top track, and the surface of the pusher plate is made of elastic nylon material. This design reduces the collision rate of frozen duck carcasses, preventing damage to the skin from external impacts that could affect product quality. Additionally, an acrylic guard plate is installed above the second conveyor belt 3 and the single-duck rejection and grading device 4.

[0045] Cooperate Figure 4 As shown, the third conveyor belt 6 has a double-layer conveying structure. The lower conveyor belt 61 is used to transport frozen duck carcass packaging boxes, and the lower conveyor belt 61 is connected to the electric turning and pushing device 12; the upper conveyor belt 62 is used to buffer or transport empty packaging boxes. This arrangement not only saves equipment space but also improves operational convenience.

[0046] Cooperate Figure 5 As shown, the printhead 101 of the inkjet printer is located on one side of the conveyor belt 102 of the inkjet printer. The inkjet printer 10 can be equipped with an automatic heating system, which can adapt to the operation of the equipment in low-temperature environments and ensure clear printing results.

[0047] Cooperate Figure 6 As shown, in order to facilitate fast and efficient transport and unloading, the fifth conveyor belt 11 is sloped downhill along the transport direction.

[0048] In summary, the low-temperature, high-humidity frozen duck carcass automatic grading and packaging production line of this utility model solves the shortcomings of relying on manual labor in the duck carcass production process, realizes automated grading and packaging production, reduces the use of manual labor, improves the efficiency of manual work, and enhances the accuracy of grading, making it suitable for widespread application.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the disclosed technical content shall fall within the protection scope of the present utility model.
