Description

Technical Field

[0001] This utility model relates to the field of livestock hair removal, specifically to a livestock hair removal device for slaughter. Background Technology

[0002] In modern livestock slaughtering processes, hair removal is one of the core steps. Because animal hair is highly susceptible to adhering environmental pollutants (including soil impurities, microorganisms, and pathogens), if livestock are not dehaired, the residual pollutants will lead to cross-contamination in subsequent processing stages, causing pathogenic microorganisms to exceed the standard and posing a significant food safety hazard. At the same time, different sizes of livestock, such as chickens, ducks, and geese, use small dehairing devices, while cattle, sheep, and pigs use larger dehairing devices.

[0003] For example, patent application number 202221719166.5 discloses a rapid dehairing device for slaughtering livestock, including a dehairing box with symmetrically distributed lower dehairing components inside, which are synchronously driven by a lower moving mechanism. An upper dehairing component is set at the upper end of the box, which is driven by an upper moving mechanism. A water spraying component is correspondingly set on the upper dehairing component.

[0004] In existing dehairing devices for livestock slaughter, although dehairing of livestock can be performed, dehairing sticks fixed on dehairing rollers are usually used to remove hair. This prevents the dehairing sticks from making sufficient contact with the animal's skin and hair, which can easily leave residual hair, reduce the effectiveness of dehairing, and also scratch the animal's skin.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes a dehairing device for livestock slaughtering to overcome the above-mentioned technical problems existing in the existing related technologies.

[0009] Furthermore, in order to achieve the dehairing operation on livestock, the dehairing assembly includes two sets of support blocks symmetrically arranged inside the dehairing box. A dehairing roller is arranged between the two sets of support blocks. Several dehairing rods 1 and 2 are respectively arranged on the outer circumference of the dehairing roller. One end of one set of support blocks penetrates the side wall of the dehairing box and is equipped with a variable frequency motor that cooperates with the dehairing roller. A fixing strip connected to the dehairing box is arranged on one side of the other set of support blocks. The dehairing rods 1 and 2 are arranged in an alternating manner in the axial direction of the dehairing roller to enhance the dehairing efficiency.

[0010] Furthermore, in order to achieve deep hair removal of livestock and adaptive contact between the hair removal roller and the livestock skin, a groove is opened on the surface of the hair removal roller and at the bottom of the first hair removal roller. A telescopic rod that cooperates with the first hair removal roller is installed in the groove.

[0024] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a dehairing device for livestock slaughter is provided.

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-5 As shown, the livestock dehairing device according to an embodiment of the present invention includes a dehairing box 1; a control panel 2 disposed on one side of the dehairing box 1; a water tank 3 disposed on the top of the dehairing box 1; a water spray head 4 disposed inside the dehairing box 1 and connected to the water tank 3; a plurality of dehairing components 5 disposed inside the dehairing box 1 to realize the dehairing operation of livestock; and a moving component 6 disposed at the bottom of the dehairing box 1 to realize the automatic placement of livestock.

[0027] With the help of the above-mentioned technical solution of this utility model, the structure of this utility model is reasonable and reliable. Through the combined action of the water spray head 4, the hair removal component 5, and the moving component 6, it can achieve deep hair removal of livestock, improve hair removal efficiency, and automatically place and remove livestock, reducing the intensity of manual labor.

[0028] It should be explained that the start command is sent through the human-machine interface (HMI) of control panel 2. This command is transmitted to the PLC programmable logic controller through the HMI. After receiving the command, the PLC precisely controls the rotation direction and number of rotations of the corresponding motor and drives the telescopic rod to move at a preset distance. This process ensures that the equipment can perform various operations according to the set requirements, thereby achieving deep and efficient hair removal for livestock. This is existing technology and will not be elaborated on here.

[0029] In one embodiment, the hair removal assembly 5 includes two sets of support blocks 501 symmetrically arranged inside the hair removal box 1. A hair removal roller 502 is arranged between the two sets of support blocks 501. A plurality of hair removal sticks 503 and hair removal sticks 504 are respectively arranged on the outer circumference of the hair removal roller 502. One end of one set of support blocks 501 penetrates the side wall of the hair removal box 1 and is equipped with a variable frequency motor 505 that cooperates with the hair removal roller 502. A fixing strip 506 connected to the hair removal box 1 is arranged on one side of the other set of support blocks 501. The hair removal sticks 503 and hair removal sticks 504 are arranged in an alternating manner in the axial direction of the hair removal roller 502 to enhance the hair removal efficiency. The surface of the hair removal roller 502 and its position A groove 507 is provided at the bottom of the first hair removal stick 503, and a telescopic rod 508 that cooperates with the first hair removal stick 503 is provided in the groove 507. A spring 509 that cooperates with the telescopic rod 508 is provided on the outer circumference of the telescopic rod 508. Several friction blocks 510 are provided on the outer circumference of the first hair removal stick 503. Several irregularly shaped hair removal teeth 511 are provided on the side of the friction blocks 510. Several friction blocks 512 are provided on the outer circumference of the second hair removal stick 504. The friction blocks 512 are quadrilateral in shape. The number and density of friction blocks 512 are greater than those of friction blocks 510, thereby enabling deep hair removal and adaptive adjustment for different qualities of livestock hair.

[0030] It should be further explained that the aforementioned hair removal stick 503 is made of hard materials (such as carbonized steel, nylon) to remove hair from livestock with hard hair, while the hair removal stick 504 is made of soft materials (such as silicone, TPE) to remove hair from livestock with soft hair. At the same time, under the action of the telescopic rod 508, the hair removal stick 503 is adaptively adjusted to reduce scratches on the animal's skin. In addition, in order to prevent the animal from jumping out of the hair removal box during hair removal, the hair removal roller 502 is rotated in opposite directions to avoid the hair removal roller 502 rotating in the same direction, forming a dynamic closed mechanical field to prevent the animal from escaping from the hair removal box 1.

[0031] The working principle of the hair removal component 5 is as follows: the operator starts the variable frequency motor 505 through the HMI interface of the control panel 2. Under the output of the variable frequency motor 505, the hair removal roller 502 is rotated in the pre-set direction. At the same time, the hair removal rod 1 503 and hair removal rod 2 504 are rotated at high speed. The jumping livestock comes into close contact with the hair removal rod 1 503 and hair removal rod 2 504. Under the wrapping of friction block 1 510 and friction block 2 512, the hair on the surface of the livestock is wrapped and removed. When the livestock applies a certain pressure to the hair removal rod 1 503, the hair removal rod 1 is driven to extend and retract under the action of the telescopic rod 508 and the spring 509 to ensure that the surface of the livestock is not subjected to excessive friction and scratches. When the hair removal stops, the worktable sends a stop signal to the variable frequency motor 505 through the HMI. The variable frequency motor 505 stops outputting the signal, so that the hair removal roller 502 stops rotating and the hair removal operation ends.

[0032] In one embodiment, the moving component 6 includes a slide rail 601 symmetrically arranged at the bottom of the hair removal box 1. A plurality of pulleys 602 cooperating with the slide rail 601 are provided at the top of the slide rail 601. A rotating shaft 603 is interspersed between the pulleys 602. A limit strip 604 is provided on the outer side of the rotating shaft 603. A support frame 605 is provided on the outer side of the rotating shaft 603. An electric telescopic rod 606 connected to the hair removal box 1 is provided at one end of the support frame 605. An electric telescopic rod 607 is provided at the top of the support frame 605. Connecting shafts 608 are symmetrically arranged on both sides of the top of the supporting frame 605. A connecting plate 609 is provided at the top of the electric telescopic rod 609. Two sets of connecting shafts 610 are provided in the middle of both sides of the connecting plate 609. A connecting strip 611 is provided on the outer circumference of the connecting shaft 608. The two sets of connecting shafts 610... Two sets of connecting strips 612 are provided on the outer side of the circumference. Connecting strips 612 are connected to connecting strips 611. Connecting strips 613 are provided on the side of connecting strips 612 away from connecting strips 611. Connecting strips 613 are provided with connecting shafts 614. Connecting blocks 615 are provided on one side of connecting shafts 614. Connecting plates 616 are provided at the top of connecting blocks 615. Connecting plates 616 have sliding grooves 617 that cooperate with fixing strips 506. Several sets of support columns 618 are provided at the top of connecting plates 616. Placement strips 619 are provided at the top of every two sets of support columns 618. A collar 620 that passes through the rotating shaft 603 is provided in the middle of the pulley 602. The inner wall of the collar 620 has a limiting groove 621 that cooperates with the limiting strip 604. This realizes automated placement of livestock, reduces the labor intensity of workers, and improves hair removal efficiency.

[0033] The working principle of the moving component 6 is as follows: After placing the dehaired livestock on top of several placement strips 619, the operator sends a start signal to the electric telescopic rod 606 through the HMI interface of the control panel 2. Upon receiving the signal, the electric telescopic rod 606 pushes the support frame 605 to move axially in the cooperation of the pulley 602 and the slide rail 601. When the electric telescopic rod 606 pushes the support frame 605 to the preset position, the operator sends a start signal to the electric telescopic rod 607 through the HMI interface. The electric telescopic rod 607 drives the connecting plate 609 to move vertically. When the connecting plate 609 rises, it drives the connecting shaft 610 to rise. At this time, the connecting strip that cooperates with the connecting shaft 610... The angle between the two 612 gradually decreases, simultaneously causing the connecting bar 611, which cooperates with the connecting shaft 608, to move upward, and causing the connecting bar 613, which cooperates with the connecting shaft 614, to move upward. At this time, the upward-moving connecting bar 613 causes the connecting shaft 614 and the connecting block 615 to move upward, and the upward-moving connecting block 615 causes the connecting plate 616 to move upward. The upward-moving connecting plate 616 causes the placement bar 619 to move upward. When the electric telescopic rod 607 moves downward, it causes the connecting plate 609 to descend. At this time, the angle between the two 612 decreases, causing the connecting bar 611 and the connecting bar 613 to descend, and causing the connecting plate 616 and the placement bar 619 to move downward.

[0034] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0035] In practical application, the staff uses the HMI on the control panel 2 to activate the electric telescopic rod 606 to move the moving component 6 out of the hair removal area of ​​the hair removal component 5, and places the animal to be haired on the placement strip 619 of the moving component 6 (the working principle of the moving component 6 is as described above). After the animal to be haired is placed in the hair removal area by the moving component, the staff uses the HMI to activate the frequency conversion motor 505 to start the hair removal roller 502 to perform the hair removal operation on the animal (the working principle of the hair removal component 5 is as described above). During hair removal, the water spray head 4 sprays hot water onto the animal through the water tank 3, making it easier for the animal's hair follicles to open and softening the hair, making the hair removal operation easier. After the hair removal operation is completed, the staff stops the operation of the hair removal component 5, activates the electric telescopic rod 607 through the HMI interface to lift the animal after hair removal, and then activates the electric telescopic rod 606 to move the animal out of the hair removal area, and repeats the next round of hair removal operation.

[0036] In summary, by means of the above-mentioned technical solution of this utility model, this utility model can automatically place and retrieve livestock, reduce the labor intensity of workers, improve the efficiency of livestock hair removal, and at the same time perform deep hair removal on livestock, improve the hair removal force, and adaptively adjust the contact with the livestock skin to reduce scratches. The hair removal component 5 performs deep hair removal on livestock, and adaptively adjusts the contact with the livestock skin to reduce skin damage while improving the hair removal effect. The moving component 6 automatically places and retrieves livestock, increases the contact distance between workers and the device, and reduces the labor force of workers in case of accidents during hair removal, thereby improving hair removal efficiency.
