Description

Technical Field

[0001] The present invention belongs to the technical field of slaughtering equipment, and in particular relates to a separating device for pig kidneys and leaf lard. Background Art

[0002] In the catering industry, leaf lard (the fat on the inner wall of the abdominal cavity of pigs) and pig kidneys are common food ingredients. Among them, leaf lard, as an important fat raw material for refining lard, has the characteristics of high oil yield, few oil residues, and mellow taste; pig kidneys, as a market for barbecue manufacturers, are deeply loved by the general public for their unique flavor.

[0003] Currently, in the slaughtering field, the separation of pig kidneys and leaf lard mainly adopts the method of manual separation using a blade. First, the leaf lard is laid flat manually, and a cut is made along one side of the pig kidney with the blade, and then the pig kidney is separated while being rolled over. During the separation process, the human hand is close to the blade, which is easy to cause accidental injury. Even though there are relatively clear operation process documents, due to the different sizes and wrapping degrees of pig kidneys during the separation process, there are certain differences in the cutting standards of different operators, and it is easy to damage the pig kidneys during the separation process, resulting in a decline in the quality of pig kidneys. The daily large amount of heavy and repetitive manual separation operations make the obtained products have poor consistency and uneven quality, and cause product devaluation.

[0004] Based on this, how to provide a separating device for pig kidneys and leaf lard to efficiently and safely separate pig kidneys and leaf lard and reduce the damage to pig kidneys is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the present invention provides a separating device for pig kidneys and leaf lard, which can replace manual operation through the separating device, efficiently and safely separate pig kidneys and leaf lard, and reduce the damage to pig kidneys.

[0006] To achieve the above object, the technical solution adopted by the present invention is: The present invention discloses a separating device for pig kidneys and leaf lard, including a frame body. A roll feeding device for receiving, squeezing and conveying pig kidneys and leaf lard is provided on the frame body. Below the conveying direction of the roll feeding device, a roll pulling device for pulling the leaf lard is provided. The separating device further includes a cutting device provided on the frame body for separating pig kidneys and leaf lard and a power device for driving the roll feeding device and the roll pulling device to work, wherein the cutting device is arranged on the same side of the roll feeding device and the roll pulling device;

[0007] After the pig kidneys and leaf lard are squeezed and conveyed by the roller feeding device, the pig kidneys remain above the roller feeding device, and the leaf lard passes through the roller feeding device and is connected to the roller pulling device, so that when the roller feeding device and the roller pulling device squeeze and pull the leaf lard, the leaf lard and the pig kidneys move to the cutting device and are cut and separated by the cutting device.

[0008] Further, the roller pulling device and the roller feeding device are inclinedly installed on the frame body, and the low end of the inclined direction faces the cutting device.

[0009] Further, the roller feeding device includes a cylindrical roller and a conical roller. The thick end of the conical roller is close to the cutting device. When the pig kidneys and the leaf lard enter the roller feeding device, the power device drives the cylindrical roller and the conical roller to work, so that the pig kidneys and the leaf lard move towards the thick end of the conical roller to enter the cutting device.

[0010] Further, the roller pulling device is arranged obliquely below the cylindrical roller and the conical roller in the biting and conveying direction. The roller pulling device includes a first pulling roller and a second pulling roller. When the leaf lard enters the roller pulling device, the power device drives the first pulling roller and the second pulling roller to work to pull the leaf lard.

[0011] Further, the surfaces of the cylindrical roller and the conical roller are smooth, and the surfaces of the first pulling roller and the second pulling roller are knurled.

[0012] Further, the cutting device includes an inclined plate and a blade. The blade is located on one side of the outlet of the thick end of the conical roller, and the inclined plate is arranged corresponding to the blade. When the leaf lard and the pig kidneys move to the end of the thick end of the conical roller, the blade cuts the leaf lard and the pig kidneys, and the separated pig kidneys fall onto the inclined plate.

[0013] Further, the distance between the cylindrical roller and the conical roller is adjustable.

[0014] Further, the power device makes the linear speed of the roller pulling device greater than the linear speed of the roller feeding device through speed reduction ratio to generate an effective pulling force for pulling the leaf lard.

[0015] Further, the power device is a combination mechanism of gear and chain drive.

[0016] Further, the power device includes a driving wheel, a first driven wheel connected to the first pulling roller, a second driven wheel connected to the second pulling roller, a third driven wheel connected to the cylindrical roller, a fourth driven wheel connected to the conical roller, and an idler wheel for adjusting the chain tension. The driving wheel is respectively connected to the fourth driven wheel and the first driven wheel, the driving wheel is respectively connected to the third driven wheel and the second driven wheel, and the diameters of the third driven wheel and the fourth driven wheel are larger than the diameters of the first driven wheel and the second driven wheel.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: A separating device for pig kidneys and leaf lard disclosed by the present invention includes a frame body. A roller feeding device for receiving, extruding and conveying pig kidneys and leaf lard is provided on the frame body. A roller pulling device for pulling leaf lard is provided below the conveying direction of the roller feeding device. The separating device further includes a cutting device provided on the frame body for separating pig kidneys and leaf lard, and a power device for driving the roller feeding device and the roller pulling device to work. When in use, a worker feeds the leaf lard connected to the pig kidney into the engaging part of the roller feeding device. Through the power input of the power device, the rollers of the roller feeding device are driven to rotate, and the leaf lard is pulled into the roller pulling device, while the pig kidney remains above the roller feeding device. Under the input of power, the roller pulling device and the roller feeding device continue to extrude and pull the leaf lard and laterally move towards the cutting device side, so that the pig kidney is extruded out of the thin film of the leaf lard under the extrusion action. The extruded pig kidney is cut when it comes into contact with the cutting device, thereby completing the separation of the pig kidney and the leaf lard. Therefore, this device can not only effectively avoid the situation that the pig kidney is cut during the separation process of the pig kidney and the leaf lard, improve the product quality, but also reduce the manual participation in the separation and cutting process of the pig kidney and the leaf lard, and reduce the labor intensity of the operator.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0025] Referring to Figures 1-4 As shown, it includes a frame 1, on which there is a roller feeding device 2 for receiving, extruding and conveying pig kidneys and leaf lard. Below the conveying direction of the roller feeding device 2, there is a roller pulling device 3 for pulling the leaf lard. It also includes a cutting device 4 arranged on the frame 1 for separating the pig kidneys and leaf lard, and a power device 5 for driving the roller feeding device 2 and the roller pulling device 3 to work;

[0026] During use, the worker feeds the leaf lard connected with the pig kidney (the pig kidney is wrapped on the leaf lard through a layer of film) into the biting part of the roller feeding device 2. The power device 5 drives the rollers of the roller feeding device 2 to rotate. The leaf lard passes through the roller feeding device 2 and enters the roller pulling device 3, while the pig kidney remains above the roller feeding device 2. Then, under the action of the power device 5, the roller pulling device 3 and the roller feeding device 2 gradually pull and extrude the leaf lard, so that the pig kidney is extruded out of the film of the leaf lard under the extrusion action. At the same time, the pig kidney and the leaf lard are laterally displaced towards the side of the cutting device 4 under the lateral displacement guiding action of the roller feeding device 2. When contacting the cutting device 4, the pig kidney and the leaf lard are cut by the cutting device to achieve the separation of the two.

[0027] Therefore, this device can not only effectively avoid the situation that the pig kidney is cut by the knife during the separation process of the pig kidney and the leaf lard, thus improving the product quality. In addition, this device also reduces the manual participation in the separation and cutting process of the pig kidney and the leaf lard, thereby reducing the labor intensity of the operator.

[0028] Continuing with the above embodiment, a more preferred solution is that in order to make the pig kidneys and leaf lard move more easily towards the cutting device 4 under the pulling action of the roller pulling device 3 and the roller feeding device 2, the roller pulling device 3 and the roller feeding device 2 are installed obliquely on the frame body 1, and the lower end of the inclined direction faces the cutting device 4. Preferably, the inclination angle is 30 degrees.

[0029] Continuing with the above embodiment, a more specifically preferred solution is that the roller feeding device 2 includes a cylindrical roller 21 and a conical roller 22. The thick end of the conical roller 22 is close to the cutting device 4. When the pig kidneys and leaf lard enter the roller feeding device 2, the power device 5 drives the cylindrical roller 21 and the conical roller 22 to work, so that the pig kidneys and leaf lard move towards the thick end of the conical roller 22, and thus can enter the cutting device 4. When in use, because the conical roller 22 is conical, the rotational speed of the thick end of the conical roller 22 is fast, and the rotational speed of the thin end of the conical roller 22 is slow. The pig kidneys and leaf lard entering between the cylindrical roller 21 and the conical roller 22 will be pulled by the thick end of the conical roller 22, so that the pig kidneys and leaf lard generate a directional movement during the feeding process, and thus move towards the thick end of the conical roller 22, that is, towards the direction of the cutting device 4. It should be noted that the roller feeding device can also achieve a lateral movement effect through similar methods such as screw conveying, and will not be elaborated here one by one.

[0030] Continuing with the above embodiment, a more specific solution is that the roller pulling device 3 is provided obliquely below the cylindrical roller 21 and the conical roller 22 in the biting and conveying direction. The roller pulling device 3 includes a first pulling roller 31 and a second pulling roller 32. When the leaf lard enters the roller pulling device, the power device 5 drives the first pulling roller 31 and the second pulling roller 32 to work to pull the leaf lard. In one embodiment, the first pulling roller 31 and the second pulling roller 32 can be rollers with the same structure. When in use, the pig kidneys and leaf lard passing through the cylindrical roller 21 and the conical roller 22 will enter between the first pulling roller 31 and the second pulling roller 32. The first pulling roller 31 and the second pulling roller 32 continue to pull the leaf lard under the action of the power device 5, so that the leaf lard continues to move downward.

[0031] Continuing with the above embodiment, a more preferred solution is that the surfaces of the cylindrical roller 21 and the conical roller 22 are smooth, so that the leaf lard can easily pass through and enter the roller pulling device. The surfaces of the first pulling roller 31 and the second pulling roller 32 are knurled, so that the surface roughness of the rollers can be increased, and thus the rollers can better exert force to pull the leaf lard.

[0032] Continuing with the above embodiment, a more specific solution is that the cutting device 4 includes an inclined plate 41 and a blade 42. The blade 42 is located on one side of the thick-end outlet of the conical roller 22, and the inclined plate 41 is arranged corresponding to the blade 42. For example, the inclined plate 41 can be located below the blade 42. When the leaf fat and the pig kidneys move to the end of the thick end of the conical roller 22, the leaf fat and the pig kidneys are cut open by the blade 42, and the separated pig kidneys fall onto the inclined plate 41. During use, the blade 42 is installed near the end of the thick end of the conical roller 22. When the leaf fat and the pig kidneys are pulled by the roller pulling device 3 and the roller feeding device 2 to the end of the thick end of the conical roller 22, the pig kidneys have been squeezed out of the film in the leaf fat, and at this time the leaf fat enters the roller feeding device 2, and only the pig kidneys remain on the roller feeding device 2. At this time, the pig kidneys and the leaf fat continue to move towards the blade 42. The pig kidneys first slide from the thick end of the conical roller 22 onto the inclined plate 41, and contact the blade 42 during the sliding process of the pig kidneys, so that the blade 42 cuts off the ureter connecting the pig kidneys and the leaf fat, completing the separation of the pig kidneys and the leaf fat. The cut-off pig kidneys will fall onto the inclined plate 41, and the pig kidneys are conveyed to the side conveyor belt through the inclined plate 41. The leaf fat will also continue to move downward, thus passing through the roller pulling device 3 and falling onto the bottom conveyor belt, and then the pig kidneys and the leaf fat are respectively conveyed to the designated positions through the side conveyor belt and the bottom conveyor belt.

[0033] Continuing with the above embodiment, a more preferred solution is that the distance between the cylindrical roller 21 and the conical roller 22 is adjustable. By adjusting the distance between the cylindrical roller 21 and the conical roller 22, the pig kidneys and the leaf fat can move in a better direction, with stronger adaptability and meeting the actual use.

[0034] Continuing with the above embodiment, a more preferred solution is that the power device 5 through speed reduction ratio makes the linear speed of the roller pulling device 3 greater than the linear speed of the roller feeding device 2 to generate an effective pulling force to pull the leaf fat by the roller pulling device 3.

[0035] Continuing with the above embodiment, a more specific solution is that the power device 5 is a combination mechanism of gear and chain drive. The power device 5 includes a driving wheel 51, a first driven wheel 52 connected to the first pulling roller 31, a second driven wheel 53 connected to the second pulling roller 32, a third driven wheel 54 connected to the cylindrical roller 21, a fourth driven wheel 55 connected to the conical roller 22, and an idler wheel 56 for adjusting the tension of the chain 57. The tension of the chain 57 can be adjusted through the idler wheel 56. The driving wheel 51 is respectively connected to the fourth driven wheel 55 and the first driven wheel 52, and the driving wheel 51 is respectively connected to the third driven wheel 54 and the second driven wheel 53, so as to realize the driving wheel driving the first driven wheel 52, the second driven wheel 53, the third driven wheel 54 and the fourth driven wheel 55 to rotate. A handle 58 can be installed on the driving wheel 51, and power can be provided to the driving wheel 51 by manually shaking the handle 58, or the driving wheel 51 can be driven to rotate by a motor to provide power;

[0036] It should be noted that the driving wheel 51 is respectively connected to the fourth driven wheel 55 and the first driven wheel 52, indicating that the positions of the fourth driven wheel 55 and the first driven wheel 52 cannot move. The driving wheel 51 is respectively connected to the third driven wheel 54 and the second driven wheel 53, and the third driven wheel 54 and the second driven wheel 53 are assembled with the frame body 1 through long holes. This is to achieve the adjustable positions of the third driven wheel 54 and the second driven wheel 53 through the design of the long holes and the chain, that is, to finally achieve the adjustable distance between the cylindrical roller 21 and the conical roller 22 as described above;

[0037] The diameters of the third driven wheel 54 and the fourth driven wheel 55 are larger than the diameters of the first driven wheel 52 and the second driven wheel 53. Thus, under the action of the same driving force, the rotational speed of the driven wheel with a larger diameter is slower. That is to say, the rotational speeds of the first driven wheel 52 and the second driven wheel 53 are greater than the rotational speeds of the third driven wheel 54 and the fourth driven wheel 55 during actual operation. Thereby, the linear speed of the roll pulling device 3 can be greater than the linear speed of the roll feeding device 2 to generate an effective pulling force. The deceleration ratio of the power device 5 can also adopt belts or synchronous belts to produce the same speed ratio configuration effect, which will not be elaborated one by one in the present invention.

[0038] As Figure 4 shown, a blanking tray 6 is further provided on the frame body 1. The blanking tray 6 is arranged corresponding to the roll feeding device 2, so that the pig kidneys and leaf lards can be more conveniently conveyed into the roll feeding device 2 through the blanking tray 6.

[0039] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather will conform to the widest scope consistent with the principles and novel features disclosed herein.
