Description

Technical Field

[0001] The invention discloses an adaptive positioning mechanism for duck head batter injection, belonging to the technical field of food processing. Background Art

[0002] Duck heads are common food on the market. Before cutting duck heads in cutting factories, duck heads need to be dehaired. In the prior art, when dehairing duck heads, wax immersion dehairing is generally adopted, that is, the duck heads are immersed in wax liquid, and the hair on the duck heads is removed by dewaxing after the wax liquid cools down. In the prior art, the defect of wax immersion dehairing is that during wax immersion, the wax liquid easily enters the nasal cavity and oral cavity of the duck head. Since the wax liquid is solid after cooling, the wax liquid remaining in the nasal cavity is difficult to remove, which affects the quality of the duck head.

[0003] In order to prevent the wax liquid from entering the duck head and oral cavity during wax dipping, the current solution is to inject paste into the nasal cavity of the duck head before wax dipping to prevent the wax liquid from entering. The Chinese utility model patent with application number 201820262833.9 and application date February 23, 2018, and patent name "A paste spraying device for meat duck duck head" discloses a technical solution, in which a spray gun is used to spray paste into the nostrils of the duck head and into the nasal cavity and oral cavity to prevent the wax liquid from entering the nasal cavity and oral cavity during the subsequent wax dipping process. However, in actual implementation, it was found that the solution still has the following problems: because the size of each duck body is different, and the length and size of the duck neck are different, it is difficult to accurately inject the paste into the nasal cavity of the duck head when spraying the paste. Therefore, designing a technical solution that can accurately inject paste into the nasal cavity of the duck head has become an urgent problem to be solved in this field. Utility Model Content

[0005] The technical solution adopted by the utility model to solve the technical problem is: the adaptive positioning mechanism for duck head batter injection is characterized by comprising a rotating mounting plate, a plurality of driving frames are swingably arranged on the outer ring of the mounting plate, a driving guide rail is arranged on the upper part of the mounting plate, the tops of all the driving frames are in contact with the driving guide rail, and the lower part of the driving frame swings with the change of the contour of the driving guide rail.

[0006] Preferably, the driving guide rail is a special-shaped annular structure, and a protruding section protruding radially outward and a driving section adjacent to the protruding section are provided on the ring body of the driving guide rail.

[0007] Preferably, the driving frame includes a strip-shaped driving plate, the upper portion of the driving plate is rotatably connected to the edge of the mounting plate, and the top of the driving plate is tightly attached to the outer ring of the driving guide rail.

[0008] Preferably, a wheel axle is vertically fixed on the top of the driving plate, a driving wheel is arranged on the top of the wheel axle, and the driving wheel is closely attached to the outer ring of the driving guide rail.

[0009] Preferably, a driving rod is transversely fixed in the middle of the wheel axle, a driving spring is respectively fixed at both ends of the driving rod, and the other end of the driving spring is fixed to the surface of the mounting plate.

DETAILED DESCRIPTION

[0024] Figures 1 to 10 It is the best embodiment of the utility model, and the following Figures 1 to 10 The utility model is further described.

[0025] like Figure 1 The batter pouring device for duck head shown in the figure includes a positioning mechanism 9, a grouting mechanism 4 is arranged at the lower part of the positioning mechanism 9, and the positioning mechanism 9 and the grouting mechanism 4 are coaxially fixed and synchronously rotated through the main transmission shaft 3. A driving disc 1 is coaxially fixed on the top of the positioning mechanism 9, and the driving disc 1 is fixed on the top of the main transmission shaft 3.

[0026] A feeding guide rail 2 is provided on the outer ring of the driving disk 1, and a plurality of hanging racks 8 are mounted on the feeding guide rail 2. All hanging racks 8 slide along the feeding guide rail 2. All hanging racks 8 are softly connected by chains, and the far ends of the chains connecting all hanging racks 8 are connected to a driving device (such as a driving motor) to provide power for the movement of the hanging racks 8. A plurality of driving grooves are evenly provided on the outer circumference of the driving disk 1. When the hanging racks 8 move to the driving disk 1, the hanging racks 8 are clamped in the driving grooves corresponding to the outer ring of the driving disk 1, and drive the driving disk 1 to rotate. While the driving disk 1 rotates, it drives the positioning mechanism 9 and the grouting mechanism 4 to rotate in sequence through the main transmission shaft 3. A base 5 is provided at the bottom of the grouting mechanism 4, and the bottom of the main transmission shaft 3 is rotatably mounted in the base 5. A distributor 6 for conveying slurry is provided between the base and the grouting mechanism 4, and the distributor 6 feeds slurry into the grouting mechanism 4.

[0027] like Figure 2~3As shown, the positioning mechanism 9 includes a mounting plate 11, which is fixed coaxially with the upper part of the main transmission shaft 3 and the main transmission shaft 3. The mounting plate 11 is located at the lower part of the driving plate 1. A plurality of driving frames 13 are swingably arranged on the outer ring of the mounting plate 11, and a driving guide rail 12 is also arranged on the upper part of the mounting plate 11, and all the driving frames 13 are located outside the driving guide rail 12 and in contact with the driving guide rail 12.

[0028] Combination Figures 4 and 5 The driving guide rail 12 is an annular guide rail of different sex, and a protruding section 15 protruding radially outward and a driving section 14 adjacent to the protruding section 15 are provided on the ring body of the driving guide rail 12. Figure 6 The driving frame 13 includes a strip-shaped driving plate 20, the top of which is hinged to one end of a hinge block 16, the other end of which is fixed to the surface of the mounting plate 11, a driving axle is vertically fixed to the top of the driving plate 20, a driving wheel 18 is arranged on the top of the driving axle, and the axle of the driving wheel 18 is fixed to the top of the driving plate 20. The driving wheel 18 is in contact with the driving guide rail 12. A driving rod 19 is transversely fixed to the middle of the driving axle, a driving spring 17 is respectively fixed to both ends of the driving rod 19, and the other end of the driving spring 17 is fixed to the surface of the mounting plate 11. A bracket 21 is also arranged on the outer side of the bottom of the driving plate 20.

[0029] When the hanging frame 8 moves to the positioning mechanism 9 with the duck body hanging on it, when the driving frame 13 contacts the hanging frame 8, the duck body is supported by the bracket 21. Since the driving frame 13 contacts the driving guide rail 12 through the driving wheel 18 on its top, the bottom of the driving frame 13 swings along the contour of the driving guide rail 12. After the hanging frame 8 enters the positioning mechanism 9 along the feeding guide rail 2, the hanging frame 8 corresponds to the driving frame 13 one by one and is set up on the outside of the driving frame 13. When the driving frame 13 rotates to the protruding section 15, the driving wheel 18 is located at the outermost side, and at the same time, under the action of the hinge block 16, the lower part of the driving frame 13 is located at the innermost side. When the driving frame 13 continues to rotate to the driving section 14, the upper part of the driving frame 13 contracts radially under the action of the somatic driving spring 17, and at the same time, the lower part of the driving frame 13 gradually expands outward under the action of the hinge block 16.

[0030] like Figure 7 As shown, the hanging frame 8 includes a wheel frame 23, the upper end of which is open, and two wheels 22 are arranged opposite to each other at the two ends of the opening. The wheel frame 23 is clamped with the feeding guide rail 2, and the wheels 22 are rollingly connected with the feeding guide rail 2. A duck hanging frame 24 is also arranged at the bottom of the wheel frame 23, and the duck body is hung on the duck hanging frame 24. When the hanging frame 8 moves to the driving disk 1, the wheel frame 23 is clamped with the driving groove on the outer periphery of the driving disk 1, thereby driving the driving disk 1 to rotate.

[0031] like Figures 8 and 9As shown, the grouting mechanism 4 includes an upper turntable 25 and a lower turntable 29, and a support tube 27 is concentrically arranged between the upper turntable 25 and the lower turntable 29. The radii of the upper turntable 25 and the lower turntable 29 are both larger than the radius of the support tube 27. The upper turntable 25 and the lower turntable 29 rotate relative to the support tube 27 under the drive of the main transmission shaft 3. A grouting drive guide rail 28 is arranged on the surface of the support tube 27. The grouting drive guide rail 28 is undulating and protrudes from the surface of the support tube 27. The head and tail ends of the grouting drive guide rail 28 overlap up and down on the surface of the support tube 27. The end of the grouting drive guide rail 28 is a horizontal section. The above-mentioned trigger mechanism includes a trigger frame 7 arranged on the outside of the base 5, and a trigger plate 32 is horizontally fixed on the top of the trigger frame 7. The trigger plate 32 corresponds to the horizontal section at the end of the grouting drive guide rail 28.

[0032] A plurality of guide rods 26 are evenly arranged on the outer ring of the support tube 27 ( Fig. 9 Only one group is shown in the figure), each group of guide rods 26 includes two parallel arranged ones, the upper end of each guide rod 26 is fixed to the lower surface of the upper turntable 25, and the lower end of each guide rod 26 is fixed to the upper surface of the lower turntable 29. A facing assembly 31 is provided at each group of guide rods 26, and the facing assembly 31 is slidably installed at the corresponding group of guide rods 26. The inner end of the facing assembly 31 contacts the surface of the grouting drive rail 28, and when the facing assembly 31 rotates the above-mentioned rotating assembly, it is simultaneously lifted and lowered under the action of the grouting drive rail 28.

[0033] A plurality of bayonet holes are evenly arranged on the outer circumference of the upper rotating disk 25, and the bayonet holes correspond to the facing components 31 one by one. Two guide rods 26 corresponding to the facing components 31 are respectively located on both sides of the bayonet holes. A pressing plate 34 corresponding to the bayonet holes is also arranged on the lower surface of the upper rotating disk 25, and the pressing plate 34 is located in the middle of the bayonet holes, that is, between the two corresponding guide rods 26.

[0034] The above-mentioned distributor 6 is arranged between the lower turntable 29 and the base 5. The distributor 6 includes an inner cylinder and an outer cylinder which are set inside and outside. A gap is left between the inner cylinder and the outer cylinder, and a sealing ring is used to seal the upper end and the lower end of the gap, so that a closed cavity is formed between the inner cylinder and the outer cylinder. The inner cylinder and the outer cylinder rotate relative to each other, and the inner cylinder is coaxially fixed with the support cylinder 27, and the outer cylinder is coaxially fixed with the above-mentioned rotating assembly. Therefore, the rotating assembly (upper turntable 25 and lower turntable 29) drives the outer cylinder to rotate at the same time when rotating.

[0035] A feed pipe 30 is provided at the bottom of the inner cylinder, and the feed pipe 30 is connected to the inner cavity of the inner cylinder. An opening is provided on the wall of the inner cylinder to connect the inner cavity of the inner cylinder with the gap between the inner cylinder and the outer cylinder. A discharge pipe 35 corresponding to the dough beating assembly 31 is provided on the wall of the outer cylinder. The feed end of the discharge pipe 35 is connected to the gap between the inner cylinder and the outer cylinder. Therefore, after the material (paste) enters through the feed pipe 30, it enters the gap between the inner cylinder and the outer cylinder through the inner cavity of the inner cylinder, and then enters each discharge pipe 35 through the gap between the inner cylinder and the outer cylinder, so that the dough is transported from the feed pipe 30 to the discharge pipe 35 while the inner cylinder and the outer cylinder rotate.

[0036] A valve 33 corresponding to the dough forming assembly 31 is provided on the outer periphery of the lower surface of the lower turntable 29 , one end of the valve 33 is connected to the discharge end of the discharge pipe 35 through a pipeline (not shown in the figure), and the other end of the valve 33 is connected to the dough forming assembly 31 .

[0037] like Fig.10 As shown, the facing assembly 31 includes a lifting block 10, and a group (two) of guide rods 26 corresponding to each group of facing assemblies 31 vertically pass through the two ends of the lifting block 10. A pulley is arranged on the back of the lifting block 10, and the wheel axle of the pulley is arranged horizontally, and the pulley is located on the surface of the grouting drive guide rail 28.

[0038] A fixed block 39 is fixed in the middle of the front surface of the lifting block 10, and a lifting rod 40 is vertically penetrated at both ends of the fixed block 39. The bottoms of the lifting rods 40 at both ends of each fixed block 39 are connected by a connecting plate. A lifting spring 38 is respectively mounted on the outside of the two lifting rods 40, and the two lifting springs 38 are both located at the upper part of the fixed block 39. A fixed seat 37 is fixed on the top of the two lifting rods 40, and the upper surface of the fixed seat 37 is an inclined surface, and a pouring block 36 is arranged at the inclined surface. The upper surface of the pouring block 36 is an opening, and a discharge port is arranged in the middle of the opening. The other end of the discharge port is provided with an interface, which penetrates the fixed seat 37 and is connected to the other end of the corresponding valve 33 through a pipeline.

[0039] The specific working process and working principle are as follows:

[0040] The hanging bracket with the head of the duck body facing downward is at the lower part of the hanging bracket 8, and moves to the driving disc 1 with the hanging bracket 8, and the duck body rotates around the driving disc 1 under the action of the feeding guide rail 2. When the hanging bracket 8 rotates to the driving disc 1, the clamping wheel frame 23 is clamped in the driving groove of the outer ring of the driving disc 1 and drives the driving disc 1 to rotate. While the driving disc 1 rotates, it drives the positioning mechanism 9 and the grouting mechanism 4 to rotate in sequence through the main transmission shaft 3.

[0041] When the hanging frame 8 moves to the positioning mechanism 9 with the duck body hanging thereon and contacts the driving frame 13, the duck body is supported by the bracket 21. Since the driving frame 13 contacts the driving guide rail 12 through the driving wheel 18 at the top thereof, the bottom of the driving frame 13 swings along the contour of the driving guide rail 12. When the driving frame 13 rotates to the protruding section 15, the driving wheel 18 is located at the outermost side, and at the same time, under the action of the hinge block 16, the lower part of the driving frame 13 is located at the innermost side, so as to ensure that the duck head of the duck body is stuck in the bayonet on the outer periphery of the upper turntable 25 and is located between the two guide rods 26 of each group.

[0042] While the duck body rotates with the upper turntable 25, the surfacing assembly 31 gradually rises along the arrangement direction of the grouting drive guide rail 28. When the surfacing assembly 31 contacts the duck head, it pushes the duck head up at the same time. When the duck head rises to the pressing plate 34 under the push of the surfacing assembly 31, the duck head is clamped by the surfacing assembly 31 and the pressing plate 34 at the same time.

[0043] At this time, the driving frame 13 rotates to the driving section 14, and the upper part of the driving frame 13 contracts radially under the action of the body-shaped driving spring 17, while the lower part of the driving frame 13 gradually expands outward under the action of the hinge block 16. The duck body is further stretched outward to ensure that the duck head can be stuck between the dough assembly 31 and the pressing plate 34.

[0044] When the facing assembly 31 and the pressing plate 34 clamp the duck head at the same time, the nasal cavity of the duck head faces the discharge port on the surface of the grouting block 36, and the facing assembly 31 moves to the horizontal section at the end of the grouting drive guide rail 28. As can be seen from the above, a trigger plate 32 is fixed on the outside of the base 5 through the trigger frame 7, and the trigger plate 32 faces the horizontal section, so the valve 33 corresponding to the current facing assembly 31 moves at the trigger plate 32.

[0045] When the lever of the valve 33 contacts the trigger plate 32, it opens under the limit of the trigger plate 32. At this time, the dough output from the distributor 6 is sent into the pouring block 36 through the discharge pipe 35 and the valve 33, and enters the nasal cavity of the duck head through the discharge port on the surface of the pouring block 36. The valve 33 is always in an open state during the process of passing through the trigger plate 32. During this process, the dough is continuously injected into the nasal cavity of the duck head and fills its mouth.

[0046] The valve 33 is realized by a common self-resetting valve available on the market. When the valve 33 rotates to the end of the trigger plate 32 and is separated from the trigger plate 32, the valve 33 is reset by its own torsion spring and closes the injection channel of the dough. At the same time, the dough assembly 31 begins to descend along the grouting drive guide rail 28, releasing the clamping of the duck head, and the duck body is transferred to the subsequent wax dipping process driven by the hanging frame 8, and this cycle repeats.

[0047] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
