Description

Technical Field

[0001] This utility model relates to the field of animal skin hair removal technology, and in particular to an animal skin hair removal mechanism. Background Technology

[0002] Enzymatic hair removal is an ideal method for removing hair from animal skin due to its high efficiency and environmental friendliness. Enzymatic hair removal involves immersing the animal skin in a hair removal device and adding a hair removal solution containing a specific concentration of protease. The protease catalyzes and hydrolyzes the epidermis and the connecting proteins between the hair root and follicle, weakening the connections between the hair root and follicle, the hair bulb and dermal papilla, and the epidermis and dermis. This allows the hair and epidermis to detach from the skin under mechanical action, thus achieving separation of the hair from the pelt.

[0003] When using a rotary drum device for hair removal, although the animal hair can be automatically removed, the shed hair remains inside the drum and cannot be discharged in time. This not only causes the animal hair to tangle and clump together, affecting the efficiency and quality of subsequent hair recycling, but also reduces the hair removal efficiency of the animal skin due to the large amount of hair absorbing the hair removal solution. Utility Model Content

[0004] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides an animal skin hair removal mechanism to achieve the discharge of animal hair to the outside of the device and avoid a large amount of animal hair remaining inside the device.

[0005] The animal skin hair removal mechanism includes:

[0006] Box;

[0007] The rotating drum is housed inside a box. A second power device installed on the outside of the box drives the rotating drum to rotate around its own circumference. The rotating drum includes a drum body. A hair removal groove is formed on the circumferential surface of the drum body. The hair removal groove extends along the axial direction of the drum body and is set at equal angles along the circumference of the drum body. A radially protruding protrusion is provided inside the drum body. The protrusion extends along the axial direction of the drum body and is arranged at equal angles along the circumference of the drum body.

[0008] A hair removal mechanism is installed inside the box. The hair removal mechanism receives animal hair discharged from the hair removal trough and sends the animal hair out of the box.

[0009] Animal hair that detaches from the animal skin under the action of biological enzymes can be discharged from the drum through the hair discharge trough. After receiving the animal hair discharged from the hair discharge trough, the hair discharge mechanism sends it out of the box, thereby realizing the discharge of animal hair to the outside of the equipment and avoiding a large amount of animal hair remaining inside the equipment.

[0010] Furthermore, the drum body is open at one end and closed at the other end;

[0011] The housing includes an outer shell, with a material inlet on one side of the outer shell. The material inlet is positioned corresponding to the open end of the drum body, through which the outside world is connected to the drum body. A sealing cap is also provided at the material inlet.

[0012] The sealing cover can be opened to put in or take out animal hides. After closing the sealing cover, it can prevent the animal hides from falling out of the feed port during the rotation of the drum. The structure is simple and easy to use.

[0013] Furthermore, the housing also includes an arc-shaped plate, which is fixed inside the outer shell. An installation cavity is formed between the arc-shaped plate and the outer shell, and a working cavity is formed on the inner side of the arc-shaped plate. The drum is set inside the working cavity.

[0014] An inlet and an outlet are provided on the opposite side of the feed inlet side. The inlet is connected to the upper part of one side of the working chamber, and the outlet is connected to the bottom of one side of the working chamber. A hair removal port is provided on the adjacent side of the feed inlet side. The hair removal port is connected to the working chamber, and the hair removal mechanism sends the animal hair out through the hair removal port.

[0015] The enclosure is divided into a working chamber for animal hair removal and a mounting chamber for electrical components by using an arc-shaped plate. This prevents the hair removal agents or other liquids from damaging the electrical components, while also avoiding direct exposure of the electrical components to the air, thus improving the safety of the equipment and making it more compact.

[0016] Furthermore, the hair removal mechanism includes:

[0017] A belt, the belt being wound around the inner and outer sides of the arc-shaped plate, the surface of the belt being in contact with the lowest height side of the hair removal opening;

[0018] An electric roller drives a belt to move.

[0019] The belt is driven by an electric roller. The belt, located in the working chamber and below the drum, receives the animal hair discharged from the hair discharge trough. The animal hair that falls onto the belt moves with the belt. When it moves to the point between the end of the arc plate and the lowest height side of the hair discharge port, the animal hair is blocked by the lowest height side of the hair discharge port, detaches from the belt, and falls to the outside, thus realizing the automatic discharge of animal hair.

[0020] Furthermore, the outer surface of the belt is provided with comb teeth.

[0021] The comb teeth move with the belt, and the comb teeth, by blocking the animal hair, carry the animal hair along with them, and the hair removal liquid is carried out by the comb teeth. As the animal hair is carried out of the hair removal liquid and moves towards the hair removal opening, the hair removal liquid attached to the animal hair will flow back into the working chamber along the gaps between the comb teeth, which improves the animal hair removal rate and reduces the hair removal liquid loss rate.

[0022] Furthermore, a downwardly inclined guide groove is connected to the side of the lowest height of the feather discharge port;

[0023] A comb tooth groove is provided on the side where the guide trough connects to the hair removal port and on the side with the lowest height of the hair removal port. The comb tooth groove is set to correspond to the comb teeth and is only for the comb teeth to pass through.

[0024] The comb teeth cause the animal hair to detach from the comb teeth and remain on the guide groove. The guide groove guides the movement of the animal hair and prevents it from sticking to the shell or the ground.

[0025] Furthermore, an arc-shaped baffle is provided inside the working chamber, which corresponds to the hair removal port.

[0026] An arc-shaped baffle forms a barrier between the hair removal port and the drum body to reduce the amount of animal hair or hair removal liquid adhering to the animal skin or the drum body being thrown out of the hair removal port due to centrifugal force during rotation.

[0027] Furthermore, it also includes a support component, on which the entire box is mounted, and the box is tilted by the support component.

[0028] Furthermore, the support component includes:

[0029] Fixed support;

[0030] A movable support, one side of which is pivotally connected to the fixed support;

[0031] The first power unit drives the pivotal movement of the movable support.

[0032] Furthermore, the support assembly also includes a connecting rod, which is driven to move linearly by a first power device, and one end of the connecting rod is pivotally connected to the movable support.

[0033] The first power unit drives the movable support to tilt, adjusting the height of the hair removal port, thereby adjusting the maximum height that the hair removal liquid can be contained in the working chamber, and then making adaptive adjustments according to the specifications or quantity of the animal skins sent in.

[0034] This utility model has the following advantages:

[0035] Animal hair that detaches from the animal skin under the action of biological enzymes can be discharged from the drum through the hair discharge trough. After receiving the animal hair discharged from the hair discharge trough, the hair discharge mechanism sends it out of the box, thereby realizing the discharge of animal hair to the outside of the equipment and avoiding a large amount of animal hair remaining inside the equipment.

[0051] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0052] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0053] As described in the background section, while automatic removal of animal hair is achieved using a rotary drum device, the shed hair remains inside the drum and cannot be discharged in a timely manner. This not only causes the animal hair to tangle and clump together, reducing the efficiency and quality of subsequent recycling, but also causes the animal hair to absorb a large amount of depilatory liquid, reducing the depilation efficiency of the animal skin.

[0054] Example 1:

[0055] Therefore, in order to solve the above-mentioned technical problems existing in the prior art, this embodiment provides an animal skin hair removal mechanism to promptly discharge the detached animal hair from the device.

[0056] like Figure 1 , 2 As shown, the animal skin hair removal mechanism includes:

[0057] Box 200;

[0058] A rotating drum 500 is housed within a housing 200. A second power device installed on the outside of the housing drives the drum to rotate circumferentially. Figure 3 As shown, the drum includes a drum body 510, on which a hair removal groove 511 is provided on the circumferential surface. The hair removal groove extends along the axial direction of the drum body and is arranged at equal angles along the circumferential direction of the drum body. A radially protruding protrusion 520 is provided inside the drum body. The protrusion extends along the axial direction of the drum body and is arranged at equal angles along the circumferential direction of the drum body.

[0059] A hair removal mechanism 600 is disposed inside the box. The hair removal mechanism receives animal hair discharged from the hair removal trough and sends the animal hair out of the box.

[0060] In this embodiment, hair removal liquid is injected into the chamber. As the liquid is continuously injected, it enters the drum through the hair removal groove. Under the action of the liquid, the epidermis of the animal skin and the connecting proteins between the hair root and the hair follicle are catalytically hydrolyzed. At the same time, the second power device drives the drum to rotate. Through the friction between the protrusions on the inner side of the drum and the animal skin, as well as between animal skins, the animal hair is quickly separated from the skin. The separated animal hair is discharged from the drum through the hair removal groove under the action of centrifugal force and its own gravity. The hair removal mechanism receives the animal hair discharged from the groove and sends it out of the chamber, thereby realizing the discharge of animal hair to the outside of the equipment and avoiding a large amount of animal hair remaining inside the equipment.

[0061] For example, the second power device can be a motor, including but not limited to a servo motor or a stepper motor. The second power device can be connected to the drum body through a belt drive mechanism, a gear drive mechanism, a sprocket drive mechanism or other transmission structures that can realize the transmission of rotational power. Alternatively, the second power device can be directly connected to the drum body.

[0062] For example, such as Figure 3 As shown, one end of the drum body is open, and the other end is closed;

[0063] like Figure 6 As shown, the housing includes an outer shell 210, and a feed port 213 is provided on one side of the outer shell. The feed port is provided corresponding to the open end of the drum body, and the outside world is connected to the drum body through the feed port. A sealing cover 400 is also provided at the feed port.

[0064] Animal hides can be inserted or removed by opening the sealing cover. Closing the sealing cover prevents the animal hides from falling out of the feed port during the rotation of the drum. The structure is simple and easy to use.

[0065] For example, a rotating shaft can be provided at one closed end of the drum body. The rotating shaft extends through the housing to the outside of the housing. A transmission mechanism can be installed on the part of the rotating shaft extending to the outside of the housing or it can be directly connected to a second power device. The rotating shaft can be connected to the side wall of the housing through a sealed bearing.

[0066] In this embodiment, as Figure 6 As shown, the housing may also include an arc-shaped plate 250, which is fixed inside the outer shell. An installation cavity 260 is formed between the arc-shaped plate and the outer shell, and a working cavity 240 is formed on the inner side of the arc-shaped plate. The drum is set inside the working cavity.

[0067] An inlet 211 and an outlet 212 are provided on the opposite side of the feed inlet side. The inlet is connected to the upper part of one side of the working chamber, and the outlet is connected to the bottom of one side of the working chamber. A hair removal port 214 is provided on the adjacent side of the feed inlet side. The hair removal port is connected to the working chamber, and the hair removal mechanism sends the animal hair out through the hair removal port.

[0068] In this embodiment, the housing is divided into a working chamber for animal hair removal and a mounting chamber for electrical components by using an arc-shaped plate. This prevents the hair removal agents or other liquids from damaging the electrical components, while also avoiding direct exposure of the electrical components to the air, thus improving the safety of the equipment and making the equipment more compact.

[0069] Exemplary, this embodiment provides one structure of the hair removal mechanism, such as Figure 6 As shown, the hair removal mechanism includes:

[0070] Belt 620, the belt is wound around the inner and outer sides of the arc-shaped plate, and the surface of the belt is in contact with the lowest height side of the hair removal opening;

[0071] The electric roller 610 drives the belt to move.

[0072] In this embodiment, the upper and lower sides of the hair removal opening are parallel to the belt and make contact with the outer surface of the belt.

[0073] The belt is driven by an electric roller. The part of the belt located in the working chamber and below the drum receives the animal hair discharged from the hair discharge trough. The animal hair that falls onto the belt moves with the belt. When it moves to the point between the end of the arc plate and the lowest height side of the hair discharge port, the animal hair is blocked by the lowest height side of the hair discharge port, detaches from the belt, and falls to the outside, thus realizing the automatic discharge of animal hair.

[0074] In this embodiment, a driven roller can be provided in the mounting cavity, the working cavity, and between the end of the arc plate and the corresponding end of the arc plate at the hair removal port. The belt is respectively wound around the electric roller and the driven roller, and the driven roller provides support for the belt.

[0075] In addition, comb teeth 630 can be provided on the outer surface of the belt.

[0076] The comb teeth move with the belt, and the comb teeth, by blocking the animal hair, carry the animal hair along with them, and the hair removal liquid is carried out by the comb teeth. As the animal hair is carried out of the hair removal liquid and moves towards the hair removal opening, the hair removal liquid attached to the animal hair will flow back into the working chamber along the gaps between the comb teeth, which improves the animal hair removal rate and reduces the hair removal liquid loss rate.

[0077] In addition, a downwardly inclined guide trough can be connected to the side of the lowest height of the discharge port;

[0078] A comb tooth groove 221 is provided on the side where the guide trough connects to the hair removal port and on the side with the lowest height of the hair removal port. The comb tooth groove is set to correspond to the comb teeth and is only for the comb teeth to pass through.

[0079] In this embodiment, since the tooth groove can only be passed through the comb teeth, and the side of the guide groove that connects to the hair removal port and the lower side of the hair removal port are tangential to and in contact with the belt, when the comb teeth pass through the tooth groove, the scraper will scoop up the hair from below and block the hair lifted by the comb teeth, so that the hair stays on the scraper surface. As the comb teeth continue to move, the hair will gradually come out of the comb teeth, eventually detach from the comb teeth, and remain on the guide groove. The guide groove guides the movement of the animal hair and prevents the animal hair from adhering to the shell or the ground.

[0080] In addition, such as Figure 5 As shown, a downwardly inclined guide trough 220 can also be connected to the side of the lowest height of the hair discharge port.

[0081] The movement of animal hair is guided by the feed trough, preventing the animal hair from adhering to the shell and making it difficult to collect.

[0082] In addition, such as Figure 6 As shown, an arc-shaped baffle can also be installed inside the working chamber, which corresponds to the hair removal port.

[0083] An arc-shaped baffle forms a barrier between the hair removal port and the drum body to reduce the amount of animal hair or hair removal liquid adhering to the animal skin and the drum body being thrown out of the hair removal port under centrifugal force during rotation.

[0084] In addition, such as Figure 1 As shown, the animal skin hair removal mechanism may also include a support component 100, on which the entire box is mounted, and the box is tilted by the support component.

[0085] like Figure 7 As shown, the support component includes:

[0086] Fixed support 110;

[0087] The movable support 120 is pivotally connected to the fixed support on one side.

[0088] The first power unit 140 drives the movable support to rotate.

[0089] In this embodiment, the first power device drives the movable support to tilt, adjusting the height of the hair removal port, thereby adjusting the maximum height that the hair removal liquid can be contained in the working chamber, and then making adaptive adjustments according to the specifications or quantity of the animal skins sent in.

[0090] For example, the first power device can be selected from power devices such as pneumatic cylinders, electric cylinders, and hydraulic cylinders. In this case, the support assembly may also include a connecting rod 130, which is driven to move linearly by the first power device. One end of the connecting rod is pivotally connected to the movable support. In this case, the first power device is pivotally mounted to the fixed support.

[0091] In addition, the first power device may also be an electric motor, which can be directly connected to the pivot shaft of the movable support to achieve the rotation of the movable support.

[0092] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
