Description

Technical Field

[0001] The utility model belongs to the field of food processing equipment, and in particular relates to a neck length self-adaptive positioning device for head and neck cutting. Background Art

[0002] Poultry is a common food in people's daily life. Since the prices of different parts of poultry are different, in addition to selling the whole poultry, the parts of the poultry body are often cut and sold separately to maximize their value. Take ducks as an example. When duck heads and duck necks are sold separately, their prices are quite different. Therefore, duck necks and duck heads need to be cut in the processing plant.

[0003] The traditional cutting method is done manually. The advantage of manual work is that the duck head and duck neck can be accurately separated. However, the labor intensity is high when it is done manually, and it is difficult to meet the hygiene requirements for food processing in the current society. Therefore, some devices that automatically cut duck necks have appeared in the prior art, such as the technical solution disclosed in the Chinese utility model patent with application number 202120555344.4, application date March 17, 2021, and patent name "A duck head cutting device"; the technical solution disclosed in the Chinese utility model patent with application number 201922391418.0, application date December 27, 2019, and patent name "A duck neck automatic cutting device", and the technical solution disclosed in the Chinese utility model patent with application number 201921982018.0, application date November 18, 2019, and patent name "An automatic duck neck cutting machine".

[0004] The prior art including the above technical solutions realizes the automatic separation of duck heads (or duck necks), greatly improving production efficiency. However, the prior art including the above technical solutions still has the following defects: since the length of the duck neck of each duck is different, and each station in the existing cutting device is relatively fixed, it is difficult to achieve accurate positioning of the duck head and duck neck, and it is difficult to achieve accurate separation of the duck head and duck neck after cutting.

[0005] Therefore, designing a technical solution for accurately positioning the duck head and duck neck before cutting so as to achieve precise cutting has become an urgent problem to be solved in this field. Utility Model Content

[0006] The technical problem to be solved by the utility model is: to overcome the shortcomings of the prior art and to provide a neck length adaptive positioning device for head and neck cutting, which, after the poultry head is stuck in the positioning mechanism, utilizes a pushing component to push the hanging mechanism and applies a radial outward pulling force to make the poultry head close to the inner side of the positioning mechanism so that the subsequent cutting mechanism can perform precise cutting of the head and neck.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the neck length adaptive positioning device for head and neck cutting includes a power mechanism, and is also provided with a hanging mechanism for hanging articles to be processed, and is characterized in that: a plurality of hanging mechanisms arranged in a ring shape are sleeved on the outside of the power mechanism and circulate through the power mechanism; a self-positioning mechanism and a transmission mechanism are coaxially fixed in sequence below the power mechanism, the self-positioning mechanism is provided with a plurality of pushing components, the pushing components correspond to the hanging mechanisms that circulate through, and radially push the corresponding hanging mechanisms, and a positioning mechanism is also provided on the surface of the transmission mechanism, and the positioning mechanism corresponds to the hanging mechanisms that circulate through at the same time.

[0008] Preferably, the self-positioning mechanism comprises a rotating disk, which rotates synchronously with the power mechanism, and a plurality of pushing components are evenly arranged on the outer circumference of the rotating disk.

[0010] Preferably, the driving wheels in all the propulsion components are arranged in a circumference, and driving guide rails are provided on the outer sides of all the driving wheels, and the driving guide rails are in the shape of a ring with a variable diameter.

[0011] Preferably, the power mechanism comprises a power disc, and a plurality of drive slots for clamping the suspension mechanism are provided on the outer circumference of the power disc.

[0012] Preferably, the hanging mechanism includes a hanger, the hanger includes a main frame, the lower part of the main frame is a clamping part for clamping with the power mechanism, and a hanging structure for hanging the items to be processed is installed at the lower part of the clamping part.

[0013] Preferably, a hanger guide rail is provided, and the hangers of all hanging mechanisms are connected to the hanger guide rail by clamping, and a group of clamping wheels for clamping with the hanger guide rail are provided at the opening on the upper part of the main frame; the hanger guide rail is an undulating structure, and the hanger guide rail is at its lowest end corresponding to the power mechanism.

[0015] Preferably, the positioning mechanism comprises a positioning plate, a bayonet is provided on the upper portion of the positioning plate, and the positioning plate is fixed to the two chains via a fixing portion at the lower portion thereof.

[0016] Compared with the prior art, the beneficial effect of the utility model is that in the neck length adaptive positioning device for head and neck cutting, after the poultry head is stuck in the positioning mechanism, the pushing component is used to push the hanging mechanism to apply a radial outward pulling force to make the poultry head close to the inner side of the positioning mechanism, so that the subsequent cutting mechanism can perform precise cutting, effectively avoiding the disadvantage of difficulty in achieving precise cutting of the head and neck due to the different lengths of the poultry necks.

The hanger guide rail is an undulating structure, and the corresponding power mechanism is at its lowest height.

[0018] In the neck length adaptive positioning device for head and neck cutting, a plurality of driving slots are opened on the outer periphery of the power disk so as to move to the hanger for clamping, and the whole soft-connected hanger is used to provide power and realize rotation.

DETAILED DESCRIPTION

[0031] Figures 1 to 11 It is the best embodiment of the utility model, and the following Figures 1 to 11 The utility model is further described.

[0032] As Figure 1~2 As shown, a neck length adaptive positioning device for head and neck cutting (hereinafter referred to as positioning device) includes a power mechanism 1, a self-positioning mechanism 2 and a support mechanism. The power mechanism 1, the self-positioning mechanism 2 and the support mechanism are coaxially arranged from top to bottom. When the power mechanism 1 rotates, the self-positioning mechanism 2 and the support mechanism are driven to rotate synchronously. In this positioning device, ducks are used as the processed objects for illustration.

[0033] The support mechanism includes a coaxially fixed support cylinder 5 and a chassis 4, and the chassis 4 is rotatably mounted on the surface of a base (not shown in the figure). The self-positioning mechanism 2 is coaxially mounted on the upper part of the support cylinder 5. Two layers of sprockets 7 are arranged from top to bottom between the self-positioning mechanism 2 and the support cylinder 5, and a chain 3 is respectively sleeved on the outside of the two layers of sprockets 7, and the other end of the chain 3 is sleeved on the outside of another group of driven sprockets (not shown in the figure) at the far end. One side of the two chains 3 is the input side of the positioning device, and the other side of the two chains 3 is the output side of the positioning device.

[0034] Several hangers 8 ( Figure 1~2Only one group is drawn in the figure), all hangers 8 are softly connected, and hanger guide rails (not shown in the figure) are arranged on the upper part of all hangers 8. All hangers 8 are clamped at the bottom of the hanger guide rails and move along the arrangement direction of the hanger guide rails. The hanger guide rails are an up and down undulating structure. When the hanger guide rails are extended to the power mechanism 1, they are at the lowest end. At this time, the hanger 8 is in contact with the power mechanism 1, and the entire hanger 8 along the hanger guide rails provides power for the rotation of the power mechanism 1. When the hanger 8 is in contact with the power mechanism 1, multiple hangers 8 provide power to the power mechanism 1 after contacting the power mechanism 1. The items to be processed (duck heads with duck necks) are hung under the hanger 8 and enter the positioning device with the hanger 8. When they are transferred to the output side of the positioning device, they are cut by the subsequent cutting device.

[0035] Multiple groups of positioning mechanisms 6 are evenly arranged at equal intervals on the outer sides of the upper and lower chains 3 ( Figure 1~2 Only one group is drawn in Fig.11 The positioning mechanism 6 includes a positioning plate 26, a "V"-shaped bayonet 25 is opened on the upper part of the positioning plate 26, and the opening of the bayonet 25 is vertically upward. The lower part of the positioning plate 26 is a fixing part, and fixing holes corresponding to the two chains 3 are opened on the surface of the fixing part, and fixing pads 28 corresponding to the positioning holes are arranged between the positioning plate 26 and the chain 3. The fixing bolts 27 pass through the fixing holes at the lower part of the positioning plate 26 and the corresponding fixing pads 28 from the outside to the inside, and are then fixed to the outer side of the corresponding chain 3.

[0036] like Figures 3-5 As shown, the power mechanism 1 includes a power disk 10, and a connecting joint 9 is coaxially arranged on the top of the power disk 10. Radially recessed drive slots 11 are evenly opened on the outer circumference of the power disk 10. When a hanger 8 moves to the power disk 10 along the hanger guide rail, it can be seen from the above that the hanger 8 is located at the lowest end of the hanger guide rail and is clamped in the drive slot 11 on the outer circumference of the power disk 10. At this time, the hanger 8 clamped in the drive slot 11 provides power for the rotation of the power disk 10. Since all hangers 8 are softly connected in sequence, multiple hangers 8 are always clamped with the drive slot 11 when moving to the power disk 10. Multiple hangers 8 clamped in the drive slot 11 provide power to the power disk 10 at the same time, driving the power disk 10 to rotate.

[0037] The hanger 8 includes a main frame 13, the top of the main frame 13 is open, and two clamping wheels 14 are arranged opposite to each other on both sides of the open end. The hanger 8 is clamped with the hanging guide rail through the clamping wheels 14 and slides along the clamping guide rail. The lower part of the main frame 13 is a vertically arranged clamping part 12, which is used to be clamped and connected with the driving clamping groove 11 on the outer periphery of the power disk 10. A hook (or a lifting ring) is installed at the lower part of the clamping part 12, and the objects to be processed are hung under the hook and move with the hanger 8.

[0038] The spacing between the hangers 8 is the same as the spacing between the positioning mechanisms 6. Therefore, when a hanger 8 moves to the power mechanism 1, a corresponding positioning mechanism 6 is set just below the hanger 8, and within the rotation range of the power disk 10, the hanger 8 and the corresponding positioning mechanism 6 rotate synchronously. When the items to be processed are hung under the hanger 8, the duck head faces inward and the duck neck faces outward. Since the hanger 8 is located at the lowest end of the hanger guide rail after moving to the power disk 10, when the hanger 8 gradually descends with the hanger guide rail, the duck neck is just stuck in its corresponding positioning mechanism 6. At this time, the duck head is located on the inner side of the upper bayonet 25 of the positioning plate 26, and the duck neck is located on the outer side of the bayonet 25.

[0039] like Figures 6 and 7 As shown, the self-positioning mechanism 2 includes a rotating disk 15 and a plurality of pushing components 16 evenly arranged on the outer circumference of the rotating disk 15 . The upper portion of the rotating disk 15 is coaxially fixed to the power disk 10 , and the lower portion of the rotating disk 15 is coaxially fixed to the sprocket 7 .

[0040] Combination Figures 8-10 The push assembly 16 includes a slide bar mounting block 18, a bottom block 23 is fixed at the bottom of the slide bar mounting block 18, and the bottom block 23 is fixed to the surface of the rotating disk 15. Two slide bars 19 arranged side by side pass through the slide bar mounting block 18 along the radial direction of the rotating disk 15. After the two slide bars 19 pass through the slide bar mounting block 18, the inner ends of the two slide bars 19 are fixed to the slide bar fixing block 24 arranged on the inner side of the slide bar mounting block 18. The driving wheel 17 is also rotatably mounted on the upper surface of the slide bar fixing block 24, and the driving wheels 17 on the upper part of all the push assemblies 16 are on the same circumference.

[0041] A driving rail (not shown) is sleeved on the outside of all driving wheels 17. When the pushing assembly 16 rotates with the rotating disk 15, the driving wheel 17 on the upper part of the pushing assembly 16 is located on the inner side of the driving rail, fits against the inner wall of the driving rail, and rotates along the driving rail. The driving rail is a variable diameter rail. In combination with the above, the hanger rail of the mounting hanger 8 is an up-and-down undulating structure. When the hanger rail extends to the power mechanism 1, it is at its lowest position, and the driving rail corresponds to the lowest position of the hanger rail where its radius is the largest.

[0042] A push plate 21 is fixed to the outer ends of the two slide bars 19, and a push rod 22 is fixed to both ends of the push plate 21. To avoid mutual interference, the push rods 22 in the two adjacent push rod assemblies 16 on the surface of the rotating disk 15 are arranged in an up-and-down staggered manner. A spring 20 is respectively mounted on the outside of the two slide bars 19, and the spring 20 is located between the push plate 21 and the slide bar mounting block 18. When the spring 20 is not subjected to external force, the push plate 21 is away from the slide bar mounting block 18 under the elastic force of the spring 20.

[0043] The specific working process and working principle are as follows: the object to be processed (the duck head with the duck neck) is hung under the hanger 8 and enters from the input side of the positioning device along with the hanger 8. Since the hanger guide rail is an up-and-down undulating structure, the hanger guide rail is at the lowest end when it extends to the power mechanism 1. When the hanger 8 moves to this point along the hanger guide rail, the hanger 8 gradually moves downward along the setting direction of the hanger guide rail.

[0044] As the hanger 8 gradually moves downward along the hanger guide rail, it is clamped in a driving slot 11 on the surface of the power disk 10, providing power for the driving slot 11 and driving the power disk 10 to rotate. At the same time, a positioning mechanism 6 that moves to the power disk 10 along with the chain 3 moves to the right below the hanger 8 and rotates synchronously with the hanger 8. As the hanger 8 gradually descends along the hanger guide rail, the duck neck is just clamped in its corresponding positioning mechanism 6, at which time the duck head is located on the inner side of the upper clamping opening 25 of the positioning plate 26, and the duck neck is located on the outer side of the clamping opening 25.

[0045] As can be seen from the above, the lowest position of the drive rails sleeved on the outside of all the drive wheels 17 in the pushing assembly 16 corresponding to the hanger rails is exactly the point where its radius is the largest. At this time, the push plate 21 is pushed away from the slide bar mounting block 18 and radially extends to the outside of the rotating disk 15 under the elastic force of the spring 20, and the push plate 21 and the push rod 22 are directly opposite to the hook below the hanger 8. In combination with the above, the duck head and duck neck are fixed by the positioning plate 26 and the hook respectively, and then the push plate 21 and the push rod 22 push the hook outward, and a radially outward pulling force is applied to the duck neck through the hook, so that the duck head is tightly attached to the inner side of the positioning plate 26, and when it is further rotated, the cutting device on the output side of the positioning device is cut, so that the accuracy of the separation of the duck head and duck neck is guaranteed under the premise of different lengths of duck necks.

[0046] After the cutting is completed, the duck head and duck neck are separated and collected respectively, the hanger 8 circulates and re-hangs the duck head to be processed, and the positioning mechanism 6 circulates with the chain 3. The driving wheel 17 on the top of the pushing assembly 16 that has just completed the action gradually rotates to the smaller radius of the driving guide rail. At this time, the driving guide rail applies a force to the driving wheel 17, and the force overcomes the elastic force of the spring 20 to retract the push plate 21 and the push rod 22 until it rotates to the maximum radius of the driving guide rail again, completing the action of pushing the duck neck, and so on.

[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.
