In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Please refer to Figures 1 to 7, the present invention provides a technical solution: a continuous packaging device for processing marinated duck, including a bottom plate 1. On the left and right sides of the top of the bottom plate 1, there are lifting frames 2. At the upper and lower ends of the opposite sides of the lifting frames 2, there are winding mechanisms 3 rotatably connected. On the left and right sides of the top of the bottom plate 1, there are support frame plates 4. In the middle of the top of the support frame plates 4, there is a height adjustment mechanism 5 vertically penetrating. At the bottom of the height adjustment mechanism 5, there is a heating mechanism 6 screwed. On one side of the top of the bottom plate 1, there is a fixed frame 7. On the opposite sides of the fixed frame 7, there is a transmission mechanism 8 rotatably connected. On the top of the transmission mechanism 8, there is a pushing mechanism 9. On the other side of the top of the bottom plate 1, there is a fixed bracket 10. Inside the fixed bracket 10, there is an air extraction mechanism 11 horizontally penetrating. In the middle of the bottom of the winding mechanism 3, there is a support table 12. On the outer wall of the top end of the height adjustment mechanism 5, there is a transmission mechanism 13 sleeved.

[0034] In this embodiment, as Figure 1 and Figure 6 shown, the lifting frame 2 includes a first electric push rod 201, a top frame 202 and a bottom frame 203. The bottom of the bottom frame 203 is arranged on the left and right sides of the top of the bottom plate 1. On both sides of the top of the bottom frame 203, there are first electric push rods 201 screwed. At the driving end of the first electric push rod 201, there is a top frame 202. It should be noted that the operator can first sleeved the packaging films on the outer walls of the upper rotating shaft 301 and the lower rotating shaft 302 respectively, and then start the transmission mechanism 8 to horizontally transport a marinated duck to directly below the heating mechanism 6 and place the marinated duck on the top of the lower packaging film so that it is between the upper and lower packaging films. At this time, the operator can start the first electric push rods 201 on both sides to drive the driving ends to drive the connected top frames 202 to descend. During this period, the upper rotating shaft 301 rotatably connected to the opposite sides of the top frame 202 will be driven to descend together, so that the packaging films sleeved on the upper rotating shaft 301 and the lower rotating shaft 302 will respectively adhere to the surface of the marinated duck, facilitating the subsequent heating and air extraction operations on the two packaging films. In actual use, through the drive of the first electric push rod 201, the lifting height of the top frame 202 can be accurately controlled, so that the upper packaging film accurately adheres to the upper surface of the marinated duck, ensuring the accuracy and stability of the packaging. And the operator only needs to start the first electric push rod 201 to realize the lifting of the top frame 202, and then complete the adhesion operation of the packaging film, greatly simplifying the packaging process and improving the work efficiency. At the same time, since the driving end of the first electric push rod 201 can drive the top frame 202 to descend by different distances, the lifting frame 2 can adapt to the packaging requirements of marinated ducks of different sizes and has good versatility.

[0035] In this embodiment, as Figure 1 and Figure 6As shown in the figure, the winding mechanism 3 includes an upper rotating shaft 301, a lower rotating shaft 302 and a first motor 303. The two ends of the two upper rotating shafts 301 are respectively rotatably connected to the opposite sides of the same-side top frame 202, and the two ends of the two lower rotating shafts 302 are respectively rotatably connected to the opposite sides of the same-side bottom frame 203. One end of the upper rotating shaft 301 and the lower rotating shaft 302 on one side is inserted with a first motor 303; it should be noted that the operator can first sleeved the packaging film on the outer walls of the upper rotating shaft 301 and the lower rotating shaft 302 respectively to form two layers of packaging film, and then convey the marinated duck to the top of the lower packaging film through the transmission mechanism 8, and perform operations such as heating and air extraction in sequence, so as to complete the vacuum packaging of the marinated duck. Then the operator can start the first motors 303 inserted at the ends of the upper rotating shaft 301 and the lower rotating shaft 302 at the same time, so that the upper rotating shaft 301 and the lower rotating shaft 302 inserted therewith are driven to rotate, thereby driving the two layers of packaging film to move horizontally and wind up, and then moving the complete packaging film directly below the heating mechanism 6. In actual use, through the rotation of the upper rotating shaft 301 and the lower rotating shaft 302, the packaging film sleeved on their outer walls can be automatically unfolded and moved to the designated position, without manual pulling of the packaging film, improving the packaging efficiency. And during the packaging process, the first motor 303 drives the upper rotating shaft 301 and the lower rotating shaft 302 to rotate, so that the packaging film maintains an appropriate tension during the unfolding and moving process, avoiding the packaging film from being slack or wrinkled, thus ensuring the packaging quality. At the same time, cooperating with other components, it can jointly complete the continuous packaging operation of the marinated duck, improving the automation degree and working efficiency of the entire packaging equipment.

[0036] In this embodiment, as Figure 2 and Figure 3 and Figure 5As shown in the figure, the height adjustment mechanism 5 includes four lifting screws 501, a moving screw plate 502, and a second motor 503. The upper and lower ends of the four lifting screws 501 are respectively rotatably connected to the top of the support frame plate 4 and one side of the bottom of the support frame plate 4. The moving screw plate 502 is screwed onto the outer walls of the four lifting screws 501, and the second motor 503 is inserted into the top end of one of the lifting screws 501. It should be noted that when the operator horizontally transports a marinated duck to directly below the heating mechanism 6 through the activation of the transmission mechanism 8 and places the marinated duck in the middle of the top of the lower packaging film, the operator can first activate the second motor 503 to drive the lifting screw 501 it is inserted into to start rotating, and drive the other three lifting screws 501 to rotate synchronously through the transmission mechanism 13, so that the moving screw plate 502 screwed onto the outer walls of the four lifting screws 501 and the heating mechanism 6 provided at the bottom of the moving screw plate 502 perform a descending operation until the heating mechanism 6 can closely adhere to the packaging film directly below, making the upper and lower packaging films adhere to the surface of the marinated duck, facilitating heating. In actual use, by driving the lifting screw 501 to rotate through the second motor 503, the descending height of the moving screw plate 502 and the heating mechanism 6 can be accurately controlled, ensuring that the heating mechanism 6 closely adheres to the packaging film, improving the heating effect and packaging quality. Moreover, the setting of the height adjustment mechanism 5 can flexibly adjust the position of the heating mechanism 6 according to the actual size of the marinated duck, ensuring the smooth progress of the packaging process. At the same time, in cooperation with the transmission mechanism 8, it can perform heating operations in a timely and accurate manner after the marinated duck is transported in place, improving the coherence and efficiency of the entire packaging process.

[0037] In this embodiment, as Figure 3 and Figure 5As shown in the figure, the heating mechanism 6 includes a second electric push rod 601, a pressing plate 602 and an electric heating wire 603. The tops of the four second electric push rods 601 are screwed to the four corners of the bottom of the moving screw plate 502, and the driving ends of the four second electric push rods 601 are arranged at the four corners of the top of the pressing plate 602. An electric heating wire 603 is arranged inside the pressing plate 602. It should be noted that after the operator moves the entire heating mechanism 6 downward through the height adjustment mechanism 5 to be close to the packaging film directly below, the operator can simultaneously activate the four second electric push rods 601, making their driving ends extend downward and push the connected pressing plate 602 to continue to descend until the bottom of the pressing plate 602 can closely fit the surface of the upper packaging film directly below, so that the upper and lower layers of packaging film are pressed together. At the same time, the electric heating wire 603 is activated to heat the pressing plate 602, so that the upper and lower layers of packaging film form a heat-sealed edge. In actual use, by using the second electric push rod 601 to push the pressing plate 602 to descend and tightly press the upper and lower layers of packaging film together, and then using the electric heating wire 603 to heat the pressing plate 602, the packaging film can form a heat-sealed edge, ensuring the sealing and integrity of the packaging. Among them, the second electric push rod 601 can adjust the pressure applied by the pressing plate 602 as needed, and the electric heating wire 603 can control the heating temperature, so as to adapt to different materials and thicknesses of packaging film, improving the adaptability and flexibility of the packaging. At the same time, the electric heating wire 603 is arranged inside the pressing plate 602, which can make the pressing plate 602 uniformly heated, so as to ensure that the upper and lower layers of packaging film are uniformly heated during the heat-sealing edge process and the edge-sealing quality is better.

[0038] In this embodiment, as Figure 5As shown in the figure, the transmission mechanism 13 includes a driving main wheel 1301, a driving driven wheel 1302 and a toothed belt 1303. The driving main wheel 1301 is sleeved on the outer wall of the top end of the lifting screw rod 501 inserted with the second motor 503. The driving driven wheel 1302 is sleeved on the outer wall of the top end of other lifting screw rods 501. The toothed belt 1303 is sleeved on the outer walls of the driving main wheel 1301 and the driving driven wheel 1302. The toothed belt 1303 meshes with the driving main wheel 1301 and the driving driven wheel 1302; it should be noted that when the operator starts the second motor 503 to drive the lifting screw rod 501 inserted therewith to start rotating, the driving main wheel 1301 sleeved on the outer wall of the top end of this lifting screw rod 501 will also rotate together, and drives the driving driven wheels 1302 in other three directions to rotate synchronously through the toothed belt 1303 sleeved on its outer wall in a meshing manner, so that the three lifting screw rods 501 sleeved on the driving driven wheel 1302 also rotate accordingly, and further enables the moving screw plates 502 and the heating mechanism 6 screwed on the outer walls of the four lifting screw rods 501 to perform a descending operation, so that the upper and lower packaging films are attached to the surface of the marinated duck, facilitating heating. In actual use, through the cooperation of the driving main wheel 1301, the driving driven wheel 1302 and the toothed belt 1303, it can ensure that the four lifting screw rods 501 rotate synchronously, so that the moving screw plates 502 and the heating mechanism 6 descend smoothly, ensuring the uniformity of the attachment of the packaging film to the marinated duck. Moreover, the setting of the transmission mechanism 13 makes the actions of the entire height adjustment mechanism 5 more coordinated, enhancing the stability and reliability of the equipment operation. At the same time, the meshing between the toothed belt 1303 and the driving main wheel 1301 and the driving driven wheel 1302 can accurately transmit power, and further enables the four lifting screw rods 501 to rotate synchronously, ensuring the accuracy and stability of the descent of the heating mechanism 6.

[0039] In this embodiment, as Figure 1 and Figure 4As shown in the figure, the transmission mechanism 8 includes a transmission main shaft 801, a transmission driven shaft 802, a transmission belt 803, and a third motor 804. The two ends of the transmission main shaft 801 and the transmission driven shaft 802 on both sides are respectively rotatably connected to the opposite sides of the same-side fixed frame 7. The outer walls of the transmission main shaft 801 and the transmission driven shaft 802 are sleeved with a transmission belt 803, and one end of the transmission main shaft 801 is inserted with a third motor 804; it should be noted that after the operator sleeved the packaging film on the outer walls of the upper rotating shaft 301 and the lower rotating shaft 302 respectively, the operator can successively place a plurality of salted ducks to be packaged on the placement plate 903 in the pushing mechanism 9, and then start the third motor 804 to drive the transmission main shaft 801 inserted therewith to start rotating, and drive the transmission driven shaft 802 on the other side to rotate together through the transmission belt 803. At the same time, several pushing mechanisms 9 containing salted ducks arranged on the top of the transmission belt 803 can be driven to perform lateral movement and transportation until one of the salted ducks is moved to the heating mechanism 6 located in the middle position, and then the salted duck is pushed to the top of the corresponding lower packaging film through the pushing mechanism 9, and then corresponding operations are carried out. In actual use, the setting of the transmission mechanism 8 can smoothly and orderly perform lateral movement and transportation on the salted ducks placed in the pushing mechanism 9, and accurately move them to the heating mechanism 6, preparing for the subsequent packaging operation. Moreover, through the setting of the transmission mechanism 8, continuous transportation of salted ducks can be achieved, greatly improving the packaging efficiency. At the same time, the setting of the transmission mechanism 8 can also enable the pushing mechanism 9 to move stably on the transmission belt 803, ensuring that the salted ducks will not shake or shift during the transportation process, and guaranteeing the accuracy and quality of the packaging.

[0040] In this embodiment, as Figure 4As shown in the figure, the pushing mechanism 9 includes a hydraulic cylinder 901, a sleeve box 902 and a placement plate 903. A number of sleeve boxes 902 are arranged on the surface of the conveyor belt 803. The hydraulic cylinder 901 is arranged inside the sleeve box 902. The driving end of the hydraulic cylinder 901 is provided with the placement plate 903. The bottom of the placement plate 903 is attached to the surface of the packaging film wound around the surface of the lower rotating shaft 302. It should be noted that the operator can first place multiple salted ducks to be packaged on the placement plates 903 at different positions in sequence, and then start the transmission mechanism 8 to drive multiple pushing mechanisms 9 for lateral transportation until one of the pushing mechanisms 9 with a salted duck moves to the heating mechanism 6 at the middle position. At the same time, the operator can start the hydraulic cylinder 901 at this position, so that its driving end starts to extend towards the packaging film, and the placement plate 903 with the salted duck is pushed to the top of the lower packaging film. At the same time, drive the driving end of the hydraulic cylinder 901 to drive the placement plate 903 to retract to its original position, so that the salted duck is placed on the top of the lower packaging film, which is convenient for subsequent operations. In actual use, through the drive of the hydraulic cylinder 901, the salted duck on the placement plate 903 can be accurately pushed to the top of the lower packaging film, ensuring the accurate position of the salted duck on the packaging film, providing an accurate positioning for the subsequent packaging process, and the operator can flexibly control the extension and retraction of the driving end of the hydraulic cylinder 901 according to needs, so as to realize the accurate pushing and reset operation of the placement plate 903 and the salted duck, improving the controllability of the packaging process. At the same time, multiple pushing mechanisms 9 can perform corresponding pushing operations according to different numbers of salted ducks, meeting the requirements of continuous packaging.

[0041] In this embodiment, as Figure 7As shown in the figure, the air extraction mechanism 11 includes an air extraction pump 1101, a telescopic tube 1102, an air extraction nozzle 1103, a third electric push rod 1104, an exhaust pipe 1105 and a connecting sleeve rod 1106. One end of the exhaust pipe 1105 is inserted into the air outlet end of the air extraction pump 1101. The air extraction end of the air extraction pump 1101 is inserted with a telescopic tube 1102. The air extraction end of the telescopic tube 1102 is provided with an air extraction nozzle 1103. The outer wall of one end of the telescopic tube 1102 is sleeved with a connecting sleeve rod 1106. The other side of the connecting sleeve rod 1106 is screwed with a third electric push rod 1104. It should be noted that after the operator pushes one of the marinated ducks to the top of the lower packaging film through the pushing mechanism 9, the operator can first start the third electric push rod 1104 to make its driving end extend towards the packaging film. During this period, the third electric push rod 1104 will drive the telescopic tube 1102 on the other side to extend synchronously through the connecting sleeve rod 1106 sleeved with it until the air extraction nozzle 1103 is stretched to the top of the lower packaging film. At the same time, the height adjustment mechanism 5 is driven to push down the heating mechanism 6 so that the upper and lower packaging films can fit on the surface of the marinated duck. During this period, the air extraction nozzle 1103 will be inside the two packaging films. Then, the air extraction pump 1101 is started to extract the air inside the packaging film through the telescopic tube 1102 and the air extraction nozzle 1103, and discharge this air through the exhaust pipe 1105, thereby completing the vacuum packaging of the marinated duck. In actual use, the setting of the air extraction mechanism 11 can effectively extract the air inside the packaging film, create a vacuum environment, thereby completing the vacuum packaging of the marinated duck, extending its shelf life, ensuring the quality and safety of food, and through the drive of the third electric push rod 1104, the position of the air extraction nozzle 1103 can be accurately controlled to ensure that it is accurately located inside the two packaging films, realizing accurate air extraction operation, improving the packaging quality, and the design of the telescopic tube 1102 enables the air extraction nozzle 1103 to be telescopic according to actual needs, adapting to the packaging requirements of marinated ducks of different sizes, with good flexibility and adaptability.

[0042] Usage method of the present invention: The continuous packaging equipment for marinated duck processing, when in use, the working process is as follows:

[0043] As Figures 1 to 7As shown in the figure, first, the operator can respectively sleeved the packaging film on the outer walls of the upper rotating shaft 301 and the lower rotating shaft 302 to form two layers of packaging film. Then, a plurality of salted ducks to be packaged are sequentially placed on the placing plate 903 in the pushing mechanism 9. Then, the third motor 804 is started to drive the transmission main shaft 801 inserted therein to start rotating, and the transmission belt 803 drives the transmission secondary shaft 802 on the other side to rotate together. At the same time, several pushing mechanisms 9 containing salted ducks on the top of the transmission belt 803 can be driven to perform transverse transportation until one of the salted ducks is moved to the heating mechanism 6 at the middle position. At the same time, the operator can start the hydraulic cylinder 901 at this position, and its driving end starts to extend towards the packaging film, driving the placing plate 903 with the salted duck to be pushed to the top of the lower packaging film. At the same time, the driving end of the hydraulic cylinder 901 is driven to drive the placing plate 903 to retract to its original position, so that the salted duck is placed on the top of the lower packaging film. Then, the third electric push rod 1104 is started, and through the connecting sleeve rod 1106, the telescopic tube 1102 on the other side is driven to extend synchronously until the air extraction nozzle 1103 is stretched to the top of the lower packaging film. At the same time, the second motor 503 is started to drive the lifting screw rod 501 inserted therein to start rotating, and the other three lifting screw rods 501 are driven to rotate synchronously through the transmission mechanism 13, so that the moving screw plates 502 screwed on the outer walls of the four lifting screw rods 501 and the heating mechanism 6 provided at the bottom of the moving screw plates 502 perform a descending operation until the heating mechanism 6 moves to a position close to the packaging film directly below. Then, the four second electric push rods 601 are started simultaneously, and their driving ends extend downward to push the pressing plate 602 connected thereto to continue descending until the bottom of the pressing plate 602 can closely fit the surface of the upper packaging film directly below, so that the upper and lower layers of packaging film are pressed together. At the same time, the electric heating wire 603 is started to heat the pressing plate 602, so that the upper and lower layers of packaging film form a heat-sealed edge. During this period, the air extraction nozzle 1103 is inside the two layers of packaging film. Then, the air extraction pump 1101 is started to extract the air inside the packaging film through the telescopic tube 1102 and the air extraction nozzle 1103, and the air is discharged through the exhaust pipe 1105, thus completing the vacuum packaging of the salted duck.
