[0097] In actual application of this embodiment: the staff can control the extension and retraction of the hydraulic rod 16 under the support of the support plate 15 according to actual needs, so that the hydraulic rod 16 uses the extension end to drive the slide plate 13 to rise and fall along the guide rod 12, and the slide plate 13 can drive the hot pressing roller 14 connected thereto to rise and fall together, thereby adjusting the gap between the upper and lower hot pressing rollers 14, and then adjusting the pressure of the hot pressing roller 14 on the skin material roller 25, so that the hot pressing roller 14 can heat and roll the skin material located between the upper and lower hot pressing rollers 14. Subsequently, the staff needs to pass the rolled skin material through the cooling ice tray 10 so that the cooling ice tray 10 cools the heated rolled skin material. The skin formed by layering and roll-pressing multiple materials can be rolled onto the outside of the winding roller 8, and the staff can fix the driving component in the base frame 4 using a fixing component, and then connect the driving end of the driving component to the end of the winding roller 8, so that the driving component can drive the winding roller 8 to rotate and roll the skin under the support of the roller seat 7.

[0098] As a preferred embodiment of the present invention, a plurality of tension rollers 19 are symmetrically provided on the inner sides of the first support frame 1 and the second support frame 2. An upper film roller 17 and a lower film roller 18 are rotatably connected to the inner side of one of the first support frames 1 close to the base frame 4, and the lower film roller 18 is located directly below the upper film roller 17. Two recovery rollers 20 are rotatably and symmetrically connected to the inner side of the first support frame 1, and the recovery roller 20 is located on the other side of the upper film roller 17 and the lower film roller 18;

[0103] As a preferred embodiment of the present invention, the cutting portion includes:

[0104] A through opening 26 is provided through the top plate 6;

[0105] The electric rod 27 is fixed on the top plate 6 and is located on one side of the opening 26;

[0106] The L-plate 28 is fixed to the telescopic end of the electric rod 27 through a connecting member and passes through the through-hole 26;

[0107] The first lifting rod 29 is fixed to the lower end of the L-plate 28 by a fixing member;

[0109] Specifically, the top plate 6 can provide a space for the opening 26, the opening 26 can provide a through channel for the L-plate 28, and the electric rod 27 can provide support for the first lifting rod 29 through the L-plate 28 under the support of the top plate 6. The first lifting rod 29 and the electric rod 27 can be extended and retracted under the control of the staff, and the first lifting rod 29 can firmly support the ultrasonic knife 30, which can use ultrasound to generate vibration to cut the covered skin.

[0110] In actual application of this embodiment, when the skin wound by the winding roller 8 reaches a set length, the staff needs to control the electric rod 27 to extend, so that the electric rod 27 uses the telescopic end to push the L plate 28 along the through hole 26, so that the L plate 28 drives the ultrasonic knife 30 to move and adjust to the cutting position through the first lifting rod 29, and then controls the first lifting rod 29 to extend, so that the first lifting rod 29 uses the telescopic end to push the ultrasonic knife 30 to descend, so that the ultrasonic knife 30 contacts the skin, and the ultrasonic knife 30 uses vibration to cut the skin during the descending process, so that the ultrasonic knife 30 can cut the skin. After cutting, the ultrasonic knife 30 needs to stop running immediately;

[0111] After the skin is cut, the staff can dismantle the roller seat 7 to remove the winding roller 8 with the wound skin, and replace it with a new winding roller 8 to position and rotate it on the roller seat 7.

[0112] As a preferred embodiment of the present invention, the clamping and moving part includes a supporting member and a clamping member, the supporting member is connected to the cutting part, and the clamping member is connected to the supporting member, and the supporting member includes:

[0113] The telescopic rod 31 is fixed to one side of the first lifting rod 29 through a fixing component;

The frame 32 can provide stable support for the side panel 33, so that the side panel 33 can provide stable support for the bevel plate 34. The bevel plate 34 has an inclined surface, which can use the inclined surface to provide resistance and sliding guidance for the conduit 50 and the bevel plate 53. The frame 32 can provide rotational support for the roller 36. The roller 36 can be supported on the skin before cutting, thereby providing support for the frame 32. During the winding movement, the skin will use friction to push the roller 36 to rotate under the support of the frame 32, so that the setting of the frame 32 will not affect the movement and winding of the skin.

[0120] The clamping hardware includes:

[0121] A first switch 37 is provided through the bevel plate 34 and is located below the ultrasonic scalpel 30;

The position of the first switch 37 corresponds to the skin, so that the ultrasonic knife 30 can squeeze the first switch 37 with the support of the angled plate 34 during the process of cutting the skin. After the first switch 37 is squeezed and triggered, it will control the extension of the second lifting rod 38. The side plate 33 can provide stable support for the connecting plate 69 through the second lifting rod 38. The connecting plate 69 can provide stable support for the elastic rope 60 and the clamp 39. The elastic rope 60 can elastically expand and contract under the action of external force.

[0129] a threaded rod 62 fixed to the other end of the pull rope 61;

[0130] The lower end of the threaded rod 62 passes through the inner wall of the upper end of the frame 32 and is threadedly connected to a support ring 63, and the support ring 63 is located outside the rubber ring 59;

[0131] The eccentric groove 64 is formed on the inner side of the support ring 63 and is located below the rubber ring 59;

[0132] The friction plate 67 is disposed in the eccentric groove 64 and is plugged into the support ring 63 .

[0133] Specifically, the roller 36 can provide stable support for the rubber ring 59. The surfaces of the rubber ring 59 and the friction plate 67 are rough and the friction force is large. The frame 32 can provide support and movement guidance for the pull rope 61, and the frame 32 can provide movement guidance for the threaded rod 62. The pull rope 61 can provide positioning support for the support ring 63 through the threaded rod 62. The inner side of the support ring 63 is symmetrically fixed with a positioning plate 65, and the positioning plate 65 is located above the eccentric groove 64. The positioning plate 65 is symmetrically provided with a socket 66. The outer side of the friction plate 67 is symmetrically fixed with an insert plate 68, and the insert plate 68 is inserted on the inner side of the insert plate 66. A bolt threadedly connected to the friction plate 67 is passed through the bottom of the support ring 63.

[0134] During actual application of this embodiment, when the ultrasonic knife 30 moves downward and cuts the skin, it will contact the first switch 37 and gradually squeeze the first switch 37 as it moves downward, so that the first switch 37 is squeezed and triggered under the support of the bevel plate 34, thereby controlling the extension of the second lifting rod 38, so that the second lifting rod 38 drives the clamp 39 to move upward through the connecting plate 69, so that the clamp 39 can use external force to drive the second switch 40 and the L support 44 to move upward together, so that the clamp 39 can contact the bottom surface of the skin. At the same time, the connecting plate 69 will pull the pull rope 61 through the elastic rope 60, so that the pull rope 61 pulls the threaded rod 62 upward under the support and guidance of the frame 32, so that the threaded rod 62 can use external force to drive the support ring 63 to move upward together, and then the support ring 63 can drive the friction plate 67 to move upward together through the bolt, positioning plate 65 and inserting plate 68. Then the friction plate 67 can contact with the rubber ring 59 and squeeze the rubber ring 59 (thereby achieving the brake fixing roller 36). Then, as the connecting plate 69 moves upward, the connecting plate 69 will continue to pull the elastic rope 60, so that the elastic rope 60 can be elastically stretched and extended until the clamp 39 contacts the bottom surface of the skin and squeezes the skin, so that the clamp 39 cooperates with the roller 36 to achieve extrusion and clamping of the skin, preventing the cut skin from producing irregular displacement and providing clamping support for the skin. After the skin is cut, the supporting force obtained by the roller 36 will disappear. At this time, the telescopic rod 31 will extend under the action of gravity, and then the frame 32 will cooperate with the roller 36 and the clamp 39 to drive the cut skin to descend together. At the same time, the wound skin material will be pulled out in the process, so that the L support 44 can be close to the replaced winding roller 8 after the electric rod 27 and the electric push rod 41 are extended.

The adhesive is injected into the rubber bag 47, which is made of transparent rubber material, which can facilitate the staff to observe the adhesive liquid level. After filling is completed, it is necessary to pay attention to threading the threaded cover 71 onto the filling pipe 70 to play a sealing role. The elastic sheet 52 can provide support for the inclined plate 53, and can be folded and deformed under the action of external force. It will rebound when the external force disappears. The inclined plate 53 can provide support for the cotton brush 35, the cotton brush 35 can provide support for the conduit 50, and the conduit 50 can provide support for the cross tube 51. The rubber bag 47 can provide a channel for the adhesive to enter the through hole 46, and the through hole 46 can provide a channel for the adhesive to enter the bellows 49. The bellows 49 can be stretched and extended under the action of external force, and will rebound and reset when the external force disappears, and can provide a channel for the adhesive to enter the conduit 50. The conduit 50 can provide a channel for the adhesive to enter the cross tube 51, and the drainage holes on the cross tube 51 can provide a discharge channel for the adhesive.

[0145] In the natural state, the elastic sheet 52 will provide support for the cotton brush 35 through the inclined plate 53 under the support of the bevel plate 34, so that the cotton brush 35 can maintain contact with the bottom of the skin and wipe the skin while the skin is being wound by the winding roller 8, preventing impurities from sticking to the bottom of the skin and affecting the adhesion of the adhesive.

[0146] The push piece includes:

[0147] A second switch 40 is embedded on the upper end of the clamp 39;

[0148] The back plate 54 is fixed to the inner side of the frame 32 and is located on the side of the L-support 44 away from the bevel plate 34;

[0149] There are two electric push rods 41, which are fixedly arranged through the back plate 54 and correspond to the positions of the L-support 44;

[0150] A T-slot 42 is formed above the telescopic end of the electric push rod 41;

[0151] A T-plate 43 is slidably disposed in the T-slot 42 and has one end fixedly connected to the L-support 44;

[0152] The side of the inclined plate 53 away from the bevel plate 34 is inclined;

[0153] The press-connecting part is arranged below the top plate 6 and extends above the winding roller 8.

[0154] Specifically, the clamp 39 can provide stable support for the second switch 40. After the second switch 40 is triggered, it will control the electric push rod 41 to extend. The back plate 54 can provide support for the electric push rod 41 under the support of the frame 32. The electric push rod 41 can provide an opening space for the T-slot 42. The T-slot 42 can provide a connection and movement guide for the T-plate 43, so that the L-support 44 can be slidably connected to the telescopic end of the electric push rod 41 through the T-plate 43 and the T-slot 42. The L-support 44 can push the inclined plate 53 downward in accordance with the inclination angle of the inclined plate 53 under the action of external force.

[0155] Press-fit parts include:

[0156] The third lifting rod 55 is fixed below the top plate 6 and is located on one side of the through opening 26;

[0157] A connecting rod 56, one end of which is fixed to the telescopic end of the third lifting rod 55 through a fixing member;

[0158] The pressure plate 57 is fixed to the other end of the connecting rod 56 by a fixing member, and the lower end is an arc surface to fit the winding roller 8;

[0159] The distance sensor 58 is fixed on the connecting rod 56 to sense the distance between the ultrasonic knife 30 and the connecting rod 56.

[0160] Specifically, the third lifting rod 55 can provide stable support for the connecting rod 56, and the connecting rod 56 can provide support for the pressure plate 57 and the ranging sensor 58. The ranging sensor 58 can control the second lifting rod 38 to retract and control the third lifting rod 55 to extend when it senses that the distance between it and the ultrasonic knife 30 is at a preset value.

[0161] In actual application of this embodiment, after the ultrasonic knife 30 descends and triggers the first switch 37, it will continue to descend, so that the ultrasonic knife 30 can be inserted into the inner side of the groove 45, so that the ultrasonic knife 30 can squeeze the rubber bag 47, so that the adhesive in the rubber bag 47 can enter the through hole 46, pass through the bellows 49 into the conduit 50, and pass through the conduit 50 into the cross pipe 51, and then fill the cross pipe 51 and be squeezed out through the discharge hole and adhered to the bottom of the skin. When the second lifting rod 38 is extended and retracted, it will drive the L support 4 through the connecting plate 69 and the clamp 39. 4 moves up and down together, and at the same time, the L support 44 will use the T plate 43 to move up and down along the T groove 42. When the clamp 39 and the roller 36 cooperate to clamp the skin, the second switch 40 will be squeezed and triggered under the support of the clamp 39, thereby controlling the electric push rod 41 to slowly extend, so that the electric push rod 41 uses the telescopic end to push the L support 44 through the clamp 39 and move toward the inclined plate 53 under the support of the back plate 54, so that the L support 44 uses the external force and its own end to contact the inclined surface of the inclined plate 53, and cooperates with the inclined surface to push the inclined plate 53 downward, so that the inclined plate 53 3 can push the elastic sheet 52 to fold and deform under the action of external force. During the downward movement of the inclined plate 53, the cotton brush 35 drives the conduit 50 to move together, so that the lower input end of the conduit 50 contacts the inclined surface of the bevel plate 34. Then, under the resistance of the inclined surface, the L-shaped support 44 pushes the external force of the inclined plate 53, so that the inclined plate 53, the cotton brush 35, the conduit 50 and the cross tube 51 can move obliquely downward along the inclined surface of the bevel plate 34 and squeeze the elastic sheet 52 to fold and deform, making way for the L-shaped support 44 to move and prevent the cross tube 51 and the conduit 50 from affecting the pressure plate 5 7 presses down the skin, and at the same time, the guide tube 50 pulls the corrugated tube 49 to extend, so that the end of the L support 44 can pass through the inclined plate 53, the cotton brush 35 and the cross tube 51 to contact the skin, thereby providing support for the cut skin. Then the staff needs to control the electric rod 27 to extend, so that it can drive the ultrasonic knife 30 to move toward the direction close to the distance sensor 58, and at the same time, it will drive the L support 44 to move toward the top of the replaced winding roller 8 through the frame 32 and the electric push rod 41, so that the L support 44 can support the cut skin above the winding roller 8 (as shown in FIG. Figure 5As shown), at the same time, the distance sensor 58 will sense that the distance between itself and the ultrasonic knife 30 has reached a preset value, thereby controlling the third lifting rod 55 to extend, so that the third lifting rod 55 drives the pressure plate 57 and the distance sensor 58 to move downward together through the connecting rod 56, so that the pressure plate 57 can contact the skin. At this time, the distance sensor 58 will sense the distance between itself and the roller 36, thereby triggering the control of the second lifting rod 38 to retract, so that the second lifting rod 38 can drive the L support 44 to move downward together through the connecting plate 69 and the clamping head 39 to release the engagement. The skin is clamped, and at the same time, the third lifting rod 55 will continue to extend to push the pressure plate 57 to move downward to squeeze the skin, so that the skin is squeezed and bent to fit the winding roller 8, and then under the action of the pressure plate 57, the adhesive arranged on the bottom surface of the skin is adhered to the winding roller 8, so that the cut skin can be adhered to the winding roller 8. After that, the third lifting rod 55, the electric push rod 41 and the electric rod 27 can be controlled to retract and reset, so that the skin on the cut equipment can be automatically moved and adhered to the new winding roller 8, thereby improving work efficiency and convenience and saving manpower.

Then, the film, the porous membrane and the prepreg are laid layer by layer in a preset order under the support of the material roller 25, the upper film roller 22 and the lower film roller 23 and the tension roller 19 to form a laying layer. During the laying process, the tension roller 19 and the winding roller 8 are used to support and control the winding tension to ≤20N and the lateral tension to ≤0.5MPa.
