Description

Technical Field

[0001] This utility model relates to the field of skin harvesting machine technology, and in particular to an electric skin harvesting machine that facilitates fixing the skin layer. Background Technology

[0002] Pigskin dermal matrix dressing is a biomaterial medical dressing made from pigskin through processes such as virus inactivation and decellularization. Pigskin dermal matrix dressing is prepared by removing the epidermis and cells of pigskin while retaining its extracellular matrix. The removal of the pigskin epidermis is usually done using a skin harvesting machine. However, the operation of existing electric skin harvesting machines is relatively cumbersome when fixing the pigskin, and the pigskin may come out of the locking device when the drum rotates, resulting in uneven thickness of the dermal layer during the cutting process. Utility Model Content

[0003] To overcome the shortcomings of the existing technology mentioned above, this utility model provides an electric skin removal machine that facilitates the fixation of the skin layer.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an electric skinning machine that facilitates fixing the skin layer, including a frame, a rotating drum connected to the frame by an external motor, a groove on the rotating drum, and a pressing device for pressing the edge of the pigskin in the groove. The pressing device includes a pressing block rotatably connected to the rotating drum by a rotating component. Corresponding positions on the bottom surface of the pressing block and the surface of the rotating drum are provided with corrugated grooves that fit each other. The length of the pressing block is greater than the length of the rotating drum. Locking blocks are fixedly connected to the lower ends of the pressing block. Locking components that cooperate with the locking blocks are provided on both sides of the rotating drum. A pressure roller and a slitting knife are arranged in sequence above the rotating drum and inside the frame in the direction of rotation of the rotating drum. In use, the edge of the pigskin is first placed in the corrugated groove, then the pressing block is pressed down, and the locking block and the locking component are engaged. Then the motor drives the rotating drum to rotate the pigskin. The pigskin is adhered to the surface of the rotating drum by the pressure roller, and finally cut by the slitting knife.

[0005] Preferably, an extension roller is provided between the pressure roller and the slitting blade. The surface of the extension roller has raised textures extending to both sides from the center line of the extension roller. In use, the pigskin is unfolded by the extension roller, which facilitates subsequent cutting.

[0006] Preferably, the locking block includes a fixing plate fixedly connected to the bottom of the pressure block, and the fixing plate has a locking block fixedly connected to both sides by a first reset spring. The top of the locking block is provided with a T-shaped slide groove, and the top two sides of the fixing plate and the bottom of the pressure block are fixedly connected with T-shaped slide rails.

[0007] Preferably, the locking component includes a locking housing with a slot inside. Pressing elements are provided on both sides of the slot. A reset plate slot is provided inside the locking housing, and a reset plate is provided in the reset plate slot. One side of the reset plate is fixedly connected to the pressing element, and the bottom of the reset plate is fixed in the reset plate slot by a second reset spring. In use, pressing the pressing elements on both sides simultaneously will cause the block to move inward along the T-shaped slide rail, allowing the block to disengage from the slot.

[0008] The beneficial effects of this utility model are that the locking parts and locking blocks can conveniently and quickly fix the edge of the pigskin, and the wave groove can increase the friction between the locking block and the pigskin, effectively improving the fixing strength and preventing the pigskin from detaching from the rotating drum, which would result in uneven thickness of the finished product.

[0018] like Figure 1-5 An electric skinning machine for easy fixation of pigskin is shown, comprising a frame 1, a rotating drum 2 connected to the frame 1 by an external motor, a groove 3 on the rotating drum 2, and a pressing device 4 for pressing the edge of the pigskin in the groove 3. The pressing device 4 includes a pressing block 5 rotatably connected to the rotating drum 2 by a rotating component. Correspondingly positioned corrugated grooves 6 on the bottom surface of the pressing block 5 and the surface of the rotating drum 2 are provided with each other. The length of the pressing block 5 is greater than the length of the rotating drum 2. Locking blocks 7 are fixedly connected to the lower ends of the pressing block 5. Locking components 8 that cooperate with the locking blocks 7 are provided on both sides of the rotating drum 2. A pressure roller 9 and a slitting knife 10 are arranged sequentially above the rotating drum 2 and inside the frame 1 in the direction of rotation of the rotating drum 2. In use, the edge of the pigskin is first placed in the corrugated groove 6, then the pressing block 5 is pressed down, and the locking block 7 and the locking component 8 are engaged. Then the motor drives the rotating drum 2 to rotate the pigskin. The pigskin adheres to the surface of the rotating drum 2 through the pressure roller 9, and finally is cut by the slitting knife 10.

[0019] An extension roller 11 is also provided between the pressure roller 9 and the slitting blade 10. The surface of the extension roller 11 has raised textures extending to both sides from the center line of the extension roller 11. When in use, the pigskin is unfolded by the extension roller 11, which facilitates subsequent cutting.

[0020] The locking block 7 includes a fixing plate 12 fixedly connected to the bottom of the pressure block 5. The fixing plate 12 has a locking block 14 fixedly connected to both sides by a first reset spring 13. The top of the locking block 14 has a T-shaped groove 15. The top two sides of the fixing plate 12 and the bottom of the pressure block 5 are fixedly connected to T-shaped slide rails 16.

[0021] The locking component 8 includes a locking housing 17, a slot 18 is provided inside the locking housing 17, and pressing components 19 are provided on both sides of the slot 18. A reset plate slot 20 is provided inside the locking housing 17, and a reset plate 21 is provided inside the reset plate slot 20. One side of the reset plate 21 is fixedly connected to the pressing component 19, and the bottom of the reset plate 21 is fixed in the reset plate slot 20 by a second reset spring 22. In use, by pressing the pressing components 19 on both sides at the same time, the locking block 14 can move inward along the T-shaped slide rail 16, so that the locking block 14 can disengage from the slot 18. Specific Implementation

[0022] In use, first place the edge of the pigskin in the wavy groove 6, then press down the pressure block 5. When the pressure block 5 is pressed down, the locking blocks 14 on both sides are squeezed by the upper section of the locking groove 18, and squeeze the first return spring 13 inward along the direction of the T-shaped slide rail 16. When the locking block 14 is fully inserted into the locking groove 18, the locking block 14 returns to its original position under the action of the first return spring 13, and locks with the locking groove 18, locking the edge of the pigskin in the wavy groove 6. Then the motor drives the rotating drum 2 to rotate the pigskin. The pigskin first adheres to the surface of the rotating drum 2 through the pressure roller 9, then unfolds through the extension roller 11, and finally is cut by the slitting knife 10.

[0023] This design is ingenious. The locking components and locking blocks can easily and quickly fix the edge of the pigskin. The corrugated groove can increase the friction between the locking block and the pigskin, effectively improving the fixing strength and preventing the pigskin from detaching from the rotating drum, which would result in uneven thickness of the finished product. In addition, the pressure roller and the extension roller make the pigskin completely adhere to the surface of the rotating drum and unfold it, which is convenient for the subsequent slitting blade to cut.

[0024] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
