Description

TECHNICAL FIELD

[0001] The present application relates to the field of raw material processing, more particularly, it relates to an automatic continuous sheep skinning machine. BACKGROUND

[0002] Sheep skinning refers to the process of separating the skin from the body of a sheep, usually for the purpose of making leather products. This process is very important in the leather manufacturing industry and affects the quality and performance of the final leather products.

[0003] By separating the sheep skin, subsequent processing of the leather such as tanning, dyeing, and finishing can be more easily performed. In some regions or processing plants, sheep skinning and processing may still use relatively outdated technology and equipment, which can result in unstable leather quality. Completely separated skin can be better processed to produce leather products.

[0004] Existing skinning machines use a roller structure to tear the sheep skin. This tearing method can cause the sheep skin to be incompletely removed, and the tearing method can cause irreversible deformation of the raw sheep skin, resulting in unstable leather quality during subsequent processing. SUMMARY

[0005] The present application provides an automatic continuous sheep skinning machine, which solves the technical problem of the existing skinning machine using a roller structure to tear the sheep skin, which can cause the sheep skin to be incompletely removed, and the tearing method can cause irreversible deformation of the raw sheep skin.

[0006] According to one aspect of the present application, an automatic continuous sheep skinning machine is provided, comprising a conveying frame for conveying a sheep to be skinned, a suspension assembly, and a skinning assembly. The conveying frame comprises two groups of conveying sections with inclined structures, and a suspension portion is provided between the two groups of conveying sections. The suspension assembly is conveyed along the conveying line of the conveying frame, and the skinning assembly is provided directly below the suspension portion. The skinning assembly is used to separate the sheep skin and meat of the sheep to be skinned.

[0007] The suspension assembly comprises four groups of independently adjustable electric hoists, and the suspension ends of the four groups of electric hoists are connected to the hooves of the sheep to be skinned. By adjusting the electric hoists, the sheep to be skinned can be switched between a vertical position and a horizontal position.

[0008] A breaking abdomen assembly is provided at the connection between the suspension portion and the conveying section. The breaking abdomen assembly is used to break the abdomen of the sheep to be skinned and separate the sheep skin and meat at the breaking abdomen position.

[0009] The abdominal dissection assembly includes an abdominal dissection knife, a skinning knife, and an adjustment component. The abdominal dissection knife has a triangular pyramidal structure, with a cutting edge on the protruding part. The skinning knife is located on the outer walls on both sides of the cutting edge. The vertical section of the skinning knife has an arc surface on the side away from the cutting edge. The skinning knife has a plow-shaped structure. The skinning knife separates the sheep skin from the mutton. The separated sheep skin is used for subsequent clamping and skinning operations.

[0010] The skinning assembly includes a base plate, a lifting cylinder, skinning arm components, and an airbag curtain. The lifting cylinder is mounted on the base plate, and the skinning arm components are mounted on one end of the piston rod of the lifting cylinder. Several sets of skinning arm components are distributed along the length of the base plate. The airbag curtain is laid on the inner wall of several sets of skinning arm components. The airbag curtain is used to vibrate the surface of the sheep's wool skin to be skinned, so as to facilitate the rapid separation of the wool skin from the mutton.

[0011] The peeling arm component includes an arm body, a drive gear set, and a clamp. One end of the arm body is provided with an arm body gear section. The drive gear set is connected to the arm body gear sections on both sides of the arm body. The clamp is installed on the other end of the arm body and is used to clamp the sheepskin part separated by the peeling knife. A drive motor is provided at the drive end of the drive gear set. The drive motor can drive the two sides of the arm body to open and close synchronously.

[0012] Furthermore, the fixture includes a fixed clamping block, a bending part, a clamping block, and a miniature cylinder. The bending part is located between the fixed clamping block and the clamping block, and the miniature cylinder is vertically inserted between the fixed clamping block and the clamping block. When the miniature cylinder retracts, it can drive the clamping block to move towards one side of the fixed clamping block.

[0013] Furthermore, the adjustment assembly includes a transverse cylinder and a longitudinal cylinder, with a connecting seat at the end of the transverse cylinder and the end of the longitudinal cylinder mounted on the connecting seat.

[0014] Furthermore, the four sets of electric hoists are electric hoist A, electric hoist B, electric hoist C and electric hoist D. Adjusting cylinders are connected in sequence between electric hoists A, B, C and D. The adjusting cylinders are used to adjust the gap and position between the four sets of electric hoists.

[0015] Furthermore, when the diaphragm assembly comes into contact with the abdomen of the sheep to be skinned, the blade of the diaphragm cuts open the sheepskin on the abdomen, and the tip of the skinning knife is pointed, which is inserted into the connection between the sheepskin and the mutton, and the sheepskin and mutton are separated by the skinning knife.

[0016] Furthermore, the drive gear set includes two meshing drive gears, which are connected to the arm body gear section. The drive gears can drive the arms on both sides to open and close synchronously.

[0017] Furthermore, when the clamp holds the separated sheepskin, the arm is driven to open and pull the sheepskin away from the mutton part until the sheepskin is only connected to the spine of the sheep to be skinned. The lifting cylinder then pulls the entire sheepskin from one side of the sheep to the other.

[0018] Furthermore, the conveying section includes a climbing section and a discharging section, which are symmetrically arranged, and spraying components are installed on both sides of the climbing section and the discharging section.

[0019] Furthermore, the spray assembly includes a spray bar and a water source, the water source being connected to one end of the spray bar via a pipe, and nozzles being distributed upwards along the spray bar.

[0020] Furthermore, the conveyor frame has a double-layer structure. The bottom layer of the conveyor frame is used to suspend the sheep to be skinned for the skinning operation, and the top layer of the conveyor frame is used to transport the skinned mutton.

[0021] The beneficial effects of this invention are as follows: This sheep skinning machine tears along the curve of the sheep's vertical cross section. During the tearing process, the tearing force that separates the sheep skin from the mutton is more uniform, and no irreversible deformation occurs on the sheep skin. Vibration is added during the tearing process to improve the separation effect of the sheep skin. When the sheep skin is located at the spine, it is lifted by one side, which can reduce the damage of the sheep skin in that part and ensure the integrity of the sheep skin separation.

Detailed Implementation

[0029] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0030] See Figures 1-6 As shown, an automated continuous sheep skinning machine includes a conveyor frame for conveying sheep to be skinned. The conveyor frame has a double-layer structure, with the bottom layer used to suspend the sheep to be skinned for skinning and the top layer used to convey the skinned mutton.

[0031] The conveyor frame includes, but is not limited to, a climbing section 100, a hanging section 300, and a discharging section 400. The climbing section 100 and the discharging section 400 are symmetrically arranged. The hanging section 300 is U-shaped, and its two ends are connected to the end of the climbing section 100 and the front end of the discharging section 400, respectively. The climbing section 100 and the discharging section 400 have a sloping structure. Spraying components 200 are installed on both sides of the climbing section 100 and the discharging section 400. The spraying components 200 in the climbing section 100 are used to clean the sheep to be skinned and to collect some of the cleaning water in the sheepskin, so as to facilitate better separation of the sheepskin from the mutton in the future. The spraying components 200 in the discharging section 400 are used to perform preliminary rinsing on the mutton after skinning.

[0032] The spray assembly 200 includes a spray bar and a water source. The water source is connected to one end of the spray bar through a pipe. Nozzles are distributed on the upward side of the spray bar.

[0033] A drive source is provided along the conveyor line of the conveyor frame. The drive source includes, but is not limited to, the conveyor chain, the conveyor belt and the sprockets and pulleys that cooperate with it. A suspension assembly 600 is installed at the bottom of the conveyor frame. The suspension end of the suspension assembly 600 is attached to the four hooves of the sheep to be skinned.

[0034] The suspension assembly 600 includes four electric hoists, each with a suspension rope 650 wound around it. The end of each suspension rope 650 is equipped with a hook 660 for attaching to or securing to the hoof part of the sheep to be skinned. The electric hoists are also connected to an electric control switch 670 for adjusting the raising and lowering of the hook 660. Specifically, this includes electric hoists A610, B620, C630, and D640. An adjusting cylinder is connected in sequence between the four sets of electric hoists (D640). The adjusting cylinder can adjust the gap and position between the four sets of electric hoists to accommodate sheep of different sizes. The four sets of electric hoists can be divided into two parts. For example, electric hoists A610 and B620 are one part, and electric hoists C630 and D640 are the other part. One part of the electric hoists is suspended at a higher position, and the other part is suspended at a lower position. At this time, the sheep to be skinned is in an upright position. When the suspension positions of the two parts are the same, the sheep to be skinned can be in a horizontal "T" shape.

[0035] A diaphragm-breaking component 500 is provided at the connection between the suspension part 300 and the climbing part 100. The diaphragm-breaking component 500 is used to diaphragm the sheep to be skinned and separate the sheep skin from the mutton at the diaphragm-breaking position. The width of the separated sheep skin is 3cm-5cm.

[0036] The abdominal incision assembly 500 includes an abdominal incision knife 510, a skin-peeling knife 520, and adjustment components, such as... Figure 6 As shown, the abdominal dissection knife 510 has a triangular pyramid structure. The protruding part of the abdominal dissection knife 510 has a cutting edge. The skinning knife 520 is located on the outer walls of both sides of the cutting edge. When the abdominal dissection component 500 contacts the abdomen of the sheep to be skinned, the cutting edge of the abdominal dissection knife 510 cuts open the sheep skin of the abdomen. The front end of the skinning knife 520 is a pointed tip, which is inserted into the connection between the sheep skin and the mutton. The vertical section of the skinning knife 520 is curved on the side away from the cutting edge. The skinning knife 520 has a plow-shaped structure. The sheep skin is separated from the mutton by the skinning knife 520. The separated sheep skin is used for subsequent clamping and skinning operations.

[0037] The adjustment assembly includes a transverse cylinder 530 and a longitudinal cylinder 540. The end of the transverse cylinder 530 is provided with a connecting seat, and the end of the longitudinal cylinder 540 is mounted on the connecting seat.

[0038] During the above abdominal dissection procedure, the sheep to be skinned should be in an upright position.

[0039] A shearing assembly 700 is also provided directly below the suspension part 300 of the conveyor frame. The shearing assembly 700 includes a base plate 710, a lifting cylinder 720, a shearing arm component 730, and an airbag curtain 740. The lifting cylinder 720 is mounted on the base plate 710, and the shearing arm component 730 is mounted on one end of the piston rod of the lifting cylinder 720. Several groups of shearing arm components 730 are distributed along the length of the base plate 710, such as... Figure 3 As shown, the airbag curtain 740 is laid on the inner wall of the three sets of skin-tearing arm components 730. The inner wall of the airbag curtain 740 is provided with several vibration points arranged in an array. Each vibration point is equipped with a vibration airbag. The vibration airbag is used to vibrate the surface of the sheep's wool skin to be skinned, so as to facilitate the rapid separation of the wool skin from the mutton.

[0040] It should be noted that the shearing component 700 also includes a box, with a hoof placement groove on the outside of the box and a wool pelt inlet at the front of the box.

[0041] The peeling arm component 730 includes an arm body 731, a drive gear set 734, and a clamp. One end of the arm body 731 is provided with an arm body gear part 732. The drive gear set 734 is connected to the arm body gear parts 732 on both sides of the arm body 731. The clamp is installed on the other end of the arm body 731. The clamp is used to clamp the sheepskin part separated by the peeling knife 520. A drive motor 733 is provided at the drive end of the drive gear set 734. The drive gear set 734 includes, but is not limited to, two drive gears. The drive gears are connected to the arm body gear parts 732. The two drive gears can drive the arm bodies 731 on both sides to open and close synchronously.

[0042] The clamp includes a fixed clamping block 735, a bending part 737, a clamping block 738, and a miniature cylinder 736. The bending part 737 is located between the fixed clamping block 735 and the clamping block 738. The miniature cylinder 736 is vertically inserted between the fixed clamping block 735 and the clamping block 738. When the miniature cylinder 736 retracts, it can drive the clamping block 738 to move towards one side of the fixed clamping block 735. When the miniature cylinder 736 returns to its original position, the bending part 737 is elastic and drives the clamping block 738 to return to its original position.

[0043] After the clamp holds the sheepskin, the arm 731 is driven by the drive motor 733 to open and pull the sheepskin away from the mutton. The sheepskin is separated until it is only connected to the spine of the sheep to be skinned. Since there is little mutton in this part, the sheepskin and mutton will be damaged if they are torn directly. At this time, the arm 731 can be used to open it up, and at the same time, the lifting cylinder 720 is used to pull the whole sheepskin from one side to the other side, that is, to tear it along the spine line, thereby improving the integrity of the sheepskin being skinned.

[0044] During the above skinning process, the sheep to be skinned should be in a horizontal position.

[0045] The specific workflow for using this skinning machine to skin a sheep is as follows:

[0046] The four hooves of the sheep to be skinned are fixed on the hanging device 660 and transported at the bottom of the conveyor frame. When transported at the climbing part 100, the sheep to be skinned is sprayed by the spraying component 200 to wash the stains on the surface of the sheepskin and at the same time to retain water in the sheepskin, so that the sheepskin and the sheep meat are dragged by gravity, which improves the separation effect of the sheepskin and the sheep meat.

[0047] When the sheep to be skinned is transported to the abdominal dissection component 500, the longitudinal cylinder 540 drives the abdominal dissection knife 510 to move from top to bottom, cutting the sheepskin along the curve of the abdomen. At the same time, the cut part is lifted by the tip of the skinning knife 520. The lifted sheepskin slides along the blade of the skinning knife 520, separating the sheepskin from the mutton, forming a separated sheepskin with a width of 3cm-5cm.

[0048] Then, when it reaches directly above the skin-tearing component 700, it can drive the four sets of electric hoists to release to the same position, causing the sheep to be skinned to be horizontal, placing the four hooves of the sheep to be skinned in the hoof placement groove, and placing the sheep to be skinned horizontally in the skin-tearing arm component 730.

[0049] Then, the clamp at the end of the skinning arm component 730 is used to hold the separated wool hide. After holding, the airbag curtain 740 is used to vibrate and loosen the mutton that needs to be skinned, making it easier to separate the wool hide and mutton later. Figure 4 As shown, the drive motor 733 and the drive gear set 734 drive the arm 731 to open to both sides, causing the wool to be continuously separated from the mutton;

[0050] When the arm 731 is fully extended, the connection between the sheepskin and the mutton is only the spine of the mutton. Then, the lifting cylinder is used to pull the sheepskin and mutton from one side to the other. At the same time, during the pulling process, the mutton changes from a horizontal position to a vertical position, which is in line with the separation of the sheepskin and mutton at the spine.

[0051] After separation, the sheepskin is output through the end of the box, and the mutton is circulated through the upper layer of the conveyor to the climbing section 100, realizing the centralized processing of the sheep to be skinned and the mutton after the skin is separated.

[0052] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
