Description

Technical Field

[0001] The present invention relates to the technical field of hair removal machines, and particularly to an efficient and non-destructive hair removal device and method for cattle heads and hooves. Background Art

[0002] A cylindrical vertical hair removal machine is a device specifically used for animal hair removal in the field of animal slaughter and processing, and plays an important role especially in the hair removal work of cattle heads and hooves. The device consists of a cylindrical barrel and a rotatable chassis located at the bottom of the barrel. A large number of rubber strips for hair removal are installed on the inner wall of the barrel and the surface of the chassis. In addition, the device is equipped with a motor drive structure for driving the chassis to rotate. During operation, the cattle head or hoof to be hair-removed is placed in the hair removal barrel. After the motor is started, the high-speed rotation of the chassis drives the cattle head or hoof to roll inside the barrel. At this time, rolling friction and sliding friction (usually both frictions exist simultaneously) are generated between the rubber strips in the barrel and the animal hair, so as to pull out the hair from the skin.

[0003] However, due to the irregular shape of the cattle head, it will produce a jumping phenomenon under the action of centrifugal force when rolling in the barrel. Generally, the jumping cattle head will hit the side wall of the barrel and generate friction with the rubber strips on the side wall, and this process will also play a role in hair removal. But at the same time, when the cattle head hits the barrel wall, the local pressure at the contact part increases significantly, which easily causes damage to the surface tissue of the cattle head, resulting in the so-called "cooked by impact" phenomenon, that is, the local tissue is denatured or damaged due to excessive force. In addition, after the cattle head hits the barrel wall, it will bounce up quickly, resulting in a short friction contact time between the skin on the surface of the cattle head and the rubber strips on the barrel wall, which further leads to poor hair removal effect. Summary of the Invention

[0004] The purpose of the present invention is to provide an efficient and non-destructive hair removal device and method for cattle heads and hooves, which solves the problems that when the existing cylindrical vertical hair removal machine processes cattle heads with irregular shapes, the local pressure is too high due to the centrifugal jump generated by the rolling of the cattle head, which is easy to damage the surface tissue, and the friction contact time is short, resulting in poor hair removal effect.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An efficient and non-destructive hair removal device for cattle heads and hooves, comprising: a machine base, on the upper side of which a barrel is fixedly assembled, and at the bottom of the cavity of the barrel, there is a rotating turntable, and the turntable is driven by a drive structure arranged inside the machine base;

[0006] A plurality of hair removal mechanisms, which are densely distributed on the upper surface of the turntable and the inner wall of the barrel, and are used for removing hair from the livestock parts rolling in the barrel;

[0007] Buffer mechanisms, multiple in number, are annularly distributed on the inner wall of the cylinder and assemble the hair removal mechanism on the inner wall of the cylinder. The buffer mechanism includes elastic strips, one end of each elastic strip elastically warps towards the middle inside the cylinder to buffer the rolling and impacting animal parts and increase the contact time. The hair removal mechanism is arranged on the side of the elastic strip away from the inner wall of the cylinder to continuously remove hair from the animal parts in long-term frictional contact.

[0008] As a further description of the above technical solution: A U-shaped part is integrally formed at one end of the elastic strip, and the end of the other end points to the rotation direction of the turntable. One side of the U-shaped part is assembled on the inner wall of the cylinder through a fixedly connected stud.

[0009] As a further description of the above technical solution: For the multiple annularly arranged elastic strips, the corresponding head and tail parts between adjacent elastic strips are in movable contact.

[0010] As a further description of the above technical solution: The elastic strip is arranged in an arc shape, and its concave surface is away from the inner wall of the cylinder.

[0011] As a further description of the above technical solution: The multiple annularly arranged elastic strips are arranged in multiple rows along the axial direction of the cylinder.

[0012] As a further description of the above technical solution: The hair removal mechanism includes multiple rubber strips, which are respectively arranged on the inner wall of the cylinder and the side of the elastic strip. The multiple rubber strips on the cylinder are circumferentially arranged in multiple circles, and the number of them outward increases in sequence, and one end of them warps upward. The rubber strips on the elastic strip are horizontally and evenly provided with multiple, and the rubber strip bends towards the middle inside the cylinder.

[0013] As a further description of the above technical solution: An adjusting mechanism for adjusting the warping angle of one end of the elastic strip is arranged inside the cylinder.

[0014] As a further description of the above technical solution: The adjusting mechanism includes a cam that abuts against the side of the elastic strip close to the inner wall of the cylinder. The cam is arranged close to the U-shaped part. Multiple cams in the same vertical direction are fixedly connected in series through a second shaft rod. Both ends of the second shaft rod are rotationally assembled by an assembly ring fixedly arranged on the inner wall of the cylinder. A control component for driving the synchronous rotation of multiple second shaft rods is arranged on the lower side of the cylinder.

[0015] As a further description of the above technical solution: A bullet-limiting mechanism for restricting the swinging of the end part is arranged inside the U-shaped part. The bullet-limiting mechanism includes a first pull rope connected to the side of the cam, and the first pull rope pulls the end part of the adjacent elastic strip.

[0016] An efficient and non-destructive hair removal method for cattle heads and hooves includes the following steps:

[0017] S1: Based on depilation of cattle heads or hooves, a control component is used to simultaneously control multiple cams to rotate simultaneously, and the ends of the control spring bars are controlled to tilt toward the inner center of the cylinder body at a preset angle;

[0018] S2: Place the cow head or cow hoof in the cylinder, then start the driving structure to drive the turntable to rotate in the direction pointed by the end, and the cow head or cow hoof rolls and jumps inside the cylinder;

[0019] S3: The cow's head or cow's hoof that jumps and hits the surface of the elastic strip will cause the elastic strip to bend and deform elastically in the direction of impact. At the same time, the deformed elastic strip will support the impacting cow's head or cow's hoof. While buffering the impact of the cow's head or cow's hoof, the elastic strip also ensures sufficient contact time, so that the rubber strip on one side of the elastic strip has sufficient time for friction contact with the cow's head or cow's hoof, while reducing the damage to the cow's head or cow's hoof caused by the impact, increasing the friction contact time and improving the hair removal efficiency.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] 1. This device is provided with elastic bars and buffer mechanisms. During the rolling process of the animal's part, the elastic bars can effectively buffer the impact of the animal's part on the inner wall of the cylinder to avoid skin damage caused by direct collision. At the same time, the continuous contact between the elastic bars and the animal's part prolongs the friction time between the depilatory mechanism and the animal's part, making the depilation effect more thorough. The depilatory mechanism is arranged on the side of the elastic bars, which further improves the depilation efficiency. The overall depilation effect is significantly better than the traditional direct contact depilation method, which effectively solves the problems of incomplete depilation and easy damage to the surface of the animal's part in the prior art.

[0022] 2. The elastic bar is designed to be arc-shaped, and the distance between its end and the inner wall of the cylinder can be flexibly adjusted by the cam in the adjustment mechanism. It can adapt to the irregular surface of the animal's part, especially the local concave part of the cow's head, to ensure that the depilatory mechanism is in full contact with the animal's part and improve the depilatory effect. The elastic limiting mechanism limits the swing of the end of the elastic bar through the first pull rope and the second pull rope, which reduces the unstable factors of the elastic bar during work, ensures the stability and continuity of the depilatory process, further improves the depilatory efficiency and quality, and enhances the versatility and applicability of the device.

Detailed implementation manners

[0036] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0038] Combined with Figures 1 - 12The invention discloses an efficient and lossless hair removal device for cattle head and hoof, comprising: a machine base 10, a cylinder 20 is fixedly mounted on the upper side of the machine base 10, a rotating turntable 13 is arranged at the bottom of the cavity of the cylinder 20, the turntable 13 is driven by a driving structure arranged inside the machine base 10, the driving structure is preferably a motor, and the turntable 13 is supported by a shaft rod 12 fixedly connected at the lower side, the motor drives the shaft rod 12 to rotate, so that the turntable 13 rotates inside the cylinder 20, the lower end of the shaft rod 12 rotates and penetrates the bottom of the machine base 10, the motor for driving the shaft rod 12 to rotate is also installed at the bottom of the machine base 10, and below the turntable 13 is a drainage trough 11, when the hair removal operation is carried out in the cylinder 20, the hair removed from the inside can be flushed out from the drainage trough 11 by continuously spraying hot water.

[0039] The barrel 20 is provided with a plurality of depilatory mechanisms 30, which are densely distributed on the upper surface of the rotating disk 13 and the inner wall of the barrel 20, and are used to depilate the animal parts rolling in the barrel 20. The animal parts in this document refer to the head or hoof of the cattle to be depilated. Before depilation, the animal parts are scalded in hot water above 60°C for a period of time, so that the skin tissue around the hair follicles becomes loose, the gripping force of the hair follicles is weakened, and the cattle hair is more likely to fall off from the hair follicles. However, when the scalded skin tissue is impacted, it is also more likely to be damaged by impact;

[0040] A plurality of buffer mechanisms 40 are distributed in an annular manner on the inner wall of the barrel 20. Compared with the prior art, the hair removal mechanism 30 originally directly assembled on the inner wall of the barrel 20 is assembled on one side of the buffer mechanism 40 in the present invention. The buffer mechanism 40 includes an elastic bar 41. A U-shaped portion 42 is integrally formed at one end of the elastic bar 41. An end portion 411 at the other end points to the rotation direction of the turntable 13. One side of the U-shaped portion 42 is assembled on the inner wall of the barrel 20 by a fixedly connected stud 43. An assembly hole 21 for the stud 43 to pass through is opened on the surface of the barrel 20. After the assembly hole 21 penetrates to the outer surface of the barrel 20, it is tightened by a nut.

[0041] like Figure 2 and Figure 8 As shown, the end 411 of the spring bar 41 elastically tilts out toward the middle of the inner side of the cylinder 20, and then combines with Figure 2 and Figure 5, when the turntable 13 rotates, it rotates clockwise, causing the livestock part to also roll clockwise. Affected by the irregular shape of the livestock part, while rolling, it also bounces. Among them, when the tumbling and bouncing livestock part touches the elastic strip 41, it will cause the elastic strip 41 to elastically deform towards the inner wall of the cylinder body 20. At the same time, the elastic strip 41 also elastically buffers the impact force of the livestock part, so as to avoid the livestock part directly hitting the inner wall of the cylinder body 20 and causing damage to the surface skin of the livestock part; in addition, during the time when the elastic strip 41 buffers the impact of the livestock part, the elastic strip 41 and the surface of the livestock part maintain contact. This greatly increases the contact time compared with the contact that occurs when the existing livestock part directly hits the inner wall of the cylinder body 20. By increasing the contact time between the elastic strip 41 and the livestock part, and then setting the hair removal mechanism 30 on the side of the elastic strip 41 away from the inner wall of the cylinder body 20, the livestock part can maintain long-term frictional contact with the hair removal mechanism 30 on the side of the elastic strip 41, so as to further carry out continuous hair removal operations on the livestock part, making the hair removal of the livestock part more thorough, and the overall hair removal efficiency has also been significantly improved.

[0042] Combined with Figures 2 - 3 and Figures 8 - 9 , for the multiple elastic strips 41 arranged in a ring, the corresponding head and tail parts between adjacent elastic strips 41 are in movable contact. The purpose of this setting is that when the livestock part frictionally slides on one side of the elastic strip 41, it can be well connected and slide onto the elastic strip 41 at the back, and the elastic strip 41 at the back can also continue to buffer the livestock part, making the entire buffering process tend to be coherent. Similarly, in this process, the process of the corresponding hair removal mechanism 30 frictionally contacting the livestock part will also be coherent, and thus the corresponding hair removal process will be more stable and efficient.

[0043] The elastic strip 41 is set in an arc shape, and its concave surface is away from the inner wall of the cylinder body 20. This is mainly to adapt to the radian of the inner wall of the cylinder body 20, so that the distance between the elastic strip 41 and the inner wall of the cylinder body 20 gradually increases along the radian direction, and the distance between the end portion 411 and the inner wall of the cylinder body 20 is the farthest distance. When the livestock part is closer to the position of the end portion 411 of the elastic strip 41, the buffering amplitude of the elastic strip 41 for the livestock part is better. Therefore, when the livestock part slides towards the end portion 411 on one side of the elastic strip 41, the elastic strip 41 can gradually buffer the livestock part for a long time, while improving the buffering effect, it also correspondingly increases the contact time and improves the hair removal effect.

[0044] As Figure 1 shown, multiple elastic strips 41 arranged in a ring are arranged in multiple rows along the axis of the cylinder body 20, and combined with Figure 12, taking the cow head as an example, for the irregular structure of the cow head, in the vertical direction, the spring strips 41 in the up-and-down relationship are under the action of elastic force and can adaptively fit to the irregular surface of the cow head, so that the hair removal mechanism 30 on the surface of the spring strip 41 can fully remove the hair from the cow head, further improving the hair removal effect. Compared with the existing setting where the hair removal mechanism 30 is directly fixed on the inner wall of the cylinder body 20, it is difficult for the locally sunken part of the cow head to have frictional contact with pressure with the hair removal mechanism 30, so the resulting hair removal effect is also insufficient. However, this embodiment well solves this technical problem.

[0045] The hair removal mechanism 30 includes a plurality of rubber strips (for small poultry such as chickens and ducks, the hair removal mechanism 30 can be a columnar rubber sleeve, which is softer in texture than the rubber strips and stands at the corresponding position, having a better hair removal effect on small poultry). The plurality of rubber strips are respectively arranged on the inner wall of the cylinder body 20 and the side surface of the spring strip 41. The plurality of rubber strips on the cylinder body 20 are circumferentially arranged in multiple circles, and the number of them outward increases in sequence, and one end is upturned. A plurality of rubber strips on the spring strip 41 are evenly arranged horizontally, and the rubber strips are bent towards the middle of the inner side of the cylinder body 20. Through such a setting, it is convenient for the rubber strips to stand on the surface of the assembled position, so as to increase the coverage area and improve the hair removal effect.

[0046] As Figures 2 - 9 shown, an adjusting mechanism 50 for adjusting the upturned angle of one end of the spring strip 41 is arranged inside the cylinder body 20. The adjusting mechanism 50 includes a cam 52 that abuts against the side of the spring strip 41 close to the inner wall of the cylinder body 20. The cam 52 is arranged close to the U-shaped part 42. Combining Figures 8 - 9 , when the cam 52 rotates clockwise, it can push the end 411 of the spring strip 41 to upturn to a larger angle on one side, promoting the improvement of the buffering ability of the spring strip 41 so as to cope with the impact force of a heavier cow head. When the cam 52 rotates clockwise, the position of the end 411 will return to its original state. At the same time, the buffering ability of the spring strip 41 will decrease accordingly, but the distance difference between the end 411 and the adjacent U-shaped part 42 will decrease. When applied to the buffering and hair removal of the cow hoof, it will make the cow hoof more natural and stable between the two spring strips 41. Correspondingly, the stable state means that the fitting state between the two is also stable, so the resulting frictional hair removal effect is also steadily improved;

[0047] Combined with Figures 5 - 7, multiple cams 52 in the same vertical direction are fixedly connected in series through the second shaft rod 51. Both ends of the second shaft rod 51 are rotationally assembled by the assembly rings 53 fixedly arranged on the inner wall of the cylinder body 20. A control assembly for driving the second shaft rods 51 to rotate synchronously is arranged on the lower side of the cylinder body 20. The control assembly includes a gear 55 fixedly connected to the lower end of the second shaft rod 51, and a toothed ring 54 that meshes with multiple gears 55 at the same time. A circular guide rail is connected to the lower side of the toothed ring 54. An electric cylinder 56 for pushing the toothed ring 54 to rotate to a preset angle is arranged on one side of the toothed ring 54. An annular groove 14 for assembling the toothed ring 54 and the electric cylinder 56 is arranged inside the machine base 10. One end of the second shaft rod 51 with the gear 55 penetrates to the inner side of the annular groove 14, and the annular groove 14 and the drainage groove 11 are not communicated with each other.

[0048] Specifically, by pushing the toothed ring 54 to rotate through the electric cylinder 56, multiple gears 55 can be driven to rotate at the same time. Further, the second shaft rod 51 that rotates with the gear 55 causes the cam 52 to rotate to a preset angle, so as to jack up the elastic strip 41 to a preset angle. Therefore, by controlling the telescopic length of the electric cylinder 56, the tilting angles of multiple elastic strips 41 can be adjusted at the same time.

[0049] In some cases, such as when the livestock part has just rolled over the elastic strip 41, the elastic potential energy originally stored by the elastic strip 41 due to elastic extrusion needs to be released. During the release of the potential energy, the end 411 of the elastic strip 41 will swing back and forth, similar to bending one end of a straight ruler. One end of the straight ruler swings back and forth quickly. This process is not conducive to the stability of the elastic strip 41 and the stable contact between the elastic strip 41 and the subsequent livestock part moving over, and is likely to affect the hair removal effect of the hair removal mechanism 30 on the surface of the elastic strip 41. Therefore, to reduce the swing of the elastic strip 41 during operation, the present solution is solved by the following implementation methods:

[0050] As Figures 9 to 11 shown, a spring limiting mechanism 60 for restricting the swing of the end 411 is arranged inside the U-shaped part 42. The spring limiting mechanism 60 includes a first pull rope 61 connected to the side of the cam 52. The first pull rope 61 pulls the end 411 of the adjacent elastic strip 41. For the time being, the second pull rope 62 and the first pull rope 61 are regarded as a complete rope, collectively referred to as the first pull rope 61. The first pull rope 61 is directly connected from one side of the cam 52 to one side of the end 411. This rope is preferably a steel wire rope or a fiber rope with a high tensile coefficient, such as a Kevlar wire. By setting the length of the first pull rope 61, a length that can prevent the elastic strip 41 from swinging can be preset in advance, so as to effectively inhibit the swing of the end 411. When the end 411 swings, once the swing amplitude exceeds the length of the first pull rope 61, it will be directly limited by the first pull rope 61, thereby preventing it from continuing to swing.

[0051] In addition, one end of the first pull rope 61 is connected to the side of the cam 52, and the other end passes through the through hole 421 on the surface of the U-shaped portion 42 and is connected to one side of the end 411. When the cam 52 rotates to one side to increase the inclination angle of the elastic bar 41, the part where the cam 52 and the first pull rope 61 are connected will also move closer to the through hole 421, so that the first pull rope 61 can release enough length through the through hole 421 to allow the corresponding connected end 411 to tilt up, thereby meeting the conditions for adjusting the inclination degree of the elastic bar 41. Figure 10 It is understood that when the cam 52 rotates clockwise, the corresponding end 411 will be prompted to move in the direction away from the inner wall of the cylinder 20. At the same time, the part where the side of the cam 52 is connected to the first pull rope 61 will also be close to the through hole 421, so that the first pull rope 61 can be released through the through hole 421, so that the end 411 can move in the direction away from the end 411.

[0052] Combination Figure 10 and Figure 11 , considering that when the cam 52 rotates, the portion of its surface used to connect the first pull rope 61 has a limited moving distance, which results in a limited length of the first pull rope 61 released through the through hole 421. Therefore, the present solution is to fix and assemble symmetrical assembly plates 65 on the inner wall of the U-shaped portion 42, and to set a fixed roller 66 with a fixed position and a movable roller 64 with a movable position between the two assembly plates 65. The movable roller 64 moves in a movable groove 651 opened on the surface of the assembly plate 65. The movable roller 64 is connected to the first pull rope 61 through a pull frame 63 connected at both ends, that is, one end of the first pull rope 61 is connected to the cam 52, and the other end is connected to the pull frame 63. The second pull rope 62 is wound around the surface of the movable roller 64 and the fixed roller 66. The second pull rope 62 is wound multiple times between the movable roller 64 and the fixed roller 66. One end of the second pull rope 62 is fixedly connected to the fixed roller 66, and the other end passes through the through hole 421 and is connected to the side of the end 411. When the cam 52 rotates toward the pulling frame 63, the movable roller 64 is brought close to the fixed roller 66, so that the length of the second pull rope 62 looped between the movable roller 64 and the fixed roller 66 is reduced. Therefore, the length of the second pull rope 62 used to pull the end 411 is doubled. The increased length of the second pull rope 62 used to limit the length of the end 411 is compared with the displacement of the movable roller 64. The displacement of the movable roller 64 also corresponds to the displacement of the connection part between the cam 52 and the first pull rope 61, thereby meeting the requirement of adjusting the end 411 to tilt outward.

[0053] A method for efficiently and non-destructively removing hair from a cow's head and hoof comprises the following steps:

[0054] S1: Based on depilation of a cow's head or hoof, a control assembly is used to simultaneously control a plurality of cams 52 to rotate simultaneously, and the end 411 of the spring bar 41 is controlled to tilt toward the inner center direction of the barrel 20 to a preset angle;

[0055] S2: Place the cow head or cow hoof inside the cylinder body 20, and then start the driving structure to drive the turntable 13 to rotate in the direction pointed by the end portion 411. At this time, the cow head or cow hoof rolls and bounces inside the cylinder body 20;

[0056] S3: The cow head or cow hoof that bounces and impacts the surface of the spring strip 41 will cause the spring strip 41 to elastically bend and deform in the impact direction. At the same time, the deforming spring strip 41 will support the impacting cow head or cow hoof. While buffering the impact force of the cow head or cow hoof, the spring strip 41 also ensures sufficient contact time, enabling the rubber strip on one side of the spring strip 41 to have sufficient time to frictionally contact the cow head or cow hoof. While reducing the damage caused by the impact of the cow head or cow hoof, it increases the friction contact time and improves the hair removal efficiency.

[0057] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.

7. The high-efficiency and non-destructive hair removal device for cattle heads and hooves according to claim 5, wherein: An adjusting mechanism (50) for adjusting the tilting angle of one end of the elastic bar (41) is arranged inside the cylinder (20).

8. The high-efficiency and non-destructive hair removal device for cattle heads and hooves according to claim 7, characterized in that: The adjusting mechanism (50) comprises a cam (52) which is pressed against the elastic bar (41) on the side close to the inner wall of the cylinder (20); the cam (52) is arranged close to the U-shaped portion (42); a plurality of cams (52) in the same vertical direction are fixedly connected in series via a second shaft rod (51); both ends of the second shaft rod (51) are rotatably assembled by an assembly ring (53) fixedly arranged on the inner wall of the cylinder (20); and a control component for driving the plurality of second shaft rods (51) to rotate synchronously is arranged on the lower side of the cylinder (20).

9. The high-efficiency and non-destructive hair removal device and method for cattle heads and hooves according to claim 8, characterized in that: A spring-limiting mechanism (60) for limiting the swing of the end portion (411) is arranged inside the U-shaped portion (42), and the spring-limiting mechanism (60) comprises a first pull rope (61) connected to the side of the cam (52), and the first pull rope (61) pulls the end portion (411) adjacent to the elastic bar (41).

10. An efficient and non-destructive hair removal method for cattle heads and hooves, characterized in that, The following steps are involved: S1: Based on depilating the head or hoof of a cow, a control component is used to simultaneously control a plurality of cams (52) to rotate simultaneously, so that the end (411) of the elastic bar (41) is controlled to tilt toward the inner center direction of the cylinder (20) at a preset angle; S2: Place the cow head or cow hoof inside the cylinder body (20), then start the driving structure to drive the turntable (13) to rotate in the direction pointed by the end portion (411). At this time, the cow head or cow hoof rolls and bounces inside the cylinder body (20); S3: The cow head or cow hoof that bounces and impacts on the surface of the spring strip (41) will cause the spring strip (41) to elastically bend and deform in the impact direction. At the same time, the deforming spring strip (41) will support the impacting cow head or cow hoof. While buffering the impact force of the cow head or cow hoof, the spring strip (41) also ensures sufficient contact time, enabling the rubber strip on one side of the spring strip (41) to have sufficient time for frictional contact with the cow head or cow hoof. While reducing the damage caused by the impact of the cow head or cow hoof, it increases the time of frictional contact and improves the hair removal efficiency.
