[0058] The structural principle and working principle of the present invention are described in detail below in conjunction with the accompanying drawings:

[0059] See also Figure 1 and Figure 2 , Figure 1 This is a schematic structural diagram of a wrapping device according to an embodiment of the present invention. Figure 2 The structure schematic diagram of the rolling roller 1 of one embodiment of the present invention. The rolling device of the sheep leather pulling machine of the present invention comprises: an outer roller 3; a rolling roller 1, which is installed on the outer roller 3 through a roller front end mechanism 2, and the rolling roller 1 comprises a driving shaft 11, a connecting plate 12 and a rolling rod 13 arranged in pairs, and the two driving shafts 11 are symmetrically installed on the roller front end mechanism 2, and each connecting plate 12 is respectively provided with a shaft mounting hole and a rod mounting hole, and the axes of the shaft mounting hole and the rod mounting hole are parallel to each other, and one end of each rolling rod 13 is installed in the rod mounting hole of the corresponding connecting plate 12, and one end of each driving shaft 11 is installed in the shaft mounting hole of the corresponding connecting plate 12. Because the axis of the driving shaft 11 is out of axis with the axis of the rolling rod 13, the driving shaft 11 forms an eccentric structure when driving the corresponding rolling rod 13 to rotate, and the eccentric structure enables the two rolling rods 13 to have a clamping position relative to each other under the drive of the corresponding connecting plate 12 (see Figure 6 ) and an open position (see Figure 7 ); and a driving mechanism 4 connected to the driving shaft 11 through a transmission mechanism 5, wherein the transmission mechanism 5 is disposed in the outer drum 3. The outer edge of the connecting plate 12 is preferably a cam structure. This embodiment may further include a signal disk 6, which is mounted on the power output shaft 41 of the reducer and is located on the side of the reducer opposite to the outer drum 3.

[0060] See also Figure 3 , Figure 3The front end mechanism 2 of the roller of one embodiment of the present invention is a schematic diagram of the structure. The front end mechanism 2 of the roller of this embodiment includes a front end cover 21 and a sleeve 22. The front end cover 21 is provided with a mounting hole for mounting the drive shaft 11. The sleeve 22 is mounted in the mounting hole. The drive shaft 11 is mounted in the sleeve 22. The front end mechanism 2 of the roller may also include a limit pin 23 for limiting the extreme position of the sector-shaped internal gear 53 when the two rolling rods 13 are in the open position. The limit pin 23 is fixedly mounted in the limit hole on the front end cover 21 to realize the positioning of the movement of the sector-shaped internal gear.

[0061] See also Figure 4 , Figure 4 It is a schematic diagram of the structure of the roll transmission mechanism 5 of an embodiment of the present invention. In this embodiment, the driving mechanism 4 is preferably a reducer. Among them, the transmission mechanism 5 plays the role of transmitting torque, including: a roller driving shaft 51, which is connected to the power output shaft 41 of the reducer by a flat key and is installed in the outer roller 3 through a bearing 57, and the end of the roller driving shaft 51 close to the reducer is provided with a dynamic friction plate 54; a sector-shaped internal gear 53, which is fixedly installed on the roller driving shaft 51 by screws; driven gears 52, which are respectively arranged corresponding to the two driving shafts 11 and mesh with each other, and the driven gears 52 are installed at one end of the corresponding driving shaft 11, and one of the driven gears 5 2 meshes with the sector-shaped internal gear 53; a friction plate push plate 55 is fixedly mounted on the end of the outer drum 3 close to the reducer by screws, and the friction plate push plate 55 and the dynamic friction plate 54 are respectively provided with mutually adapted push claws 551 and 541, and the push claws 551 and 541 are provided with mutually adapted inclined surfaces, and the inclined surfaces of the push claws 551 of the friction plate push plate 55 and the inclined surfaces of the push claws 541 of the dynamic friction plate 54 are arranged face to face; and a static friction plate 56 is fixedly mounted on the flange of the reducer by screws corresponding to the dynamic friction plate 54. The spacing between the dynamic friction plate 54 and the static friction plate 56 is preferably 1-2 mm.

[0062] See also Figures 5A-5C , Figure 5A This is a schematic diagram of the push plate structure of the dynamic friction plate 54 according to an embodiment of the present invention. Figure 5B Schematic diagram of the relative positions of the friction plate push plate 55 and the movable friction plate 54 according to an embodiment of the present invention. Figure 5C Schematic diagram of the interaction between the friction plate push plate 55 and the push claw of the dynamic friction plate 54. When the transmission mechanism 5 rotates, the friction plate push plate 55 pushes the dynamic friction plate 54 to press the static friction plate 56, so that the static friction plate 56 gives the dynamic friction plate 54 a force opposite to the rotation direction of the dynamic friction plate 54. That is, when the friction plate push plate 55 rotates, the transmission inclined surface of the push claw of the friction plate push plate 55 and the transmission inclined surface of the push claw of the dynamic friction plate 54 squeeze each other with a force F n, generating two force components F perpendicular to the power output shaft 41 of the reducer and parallel to the power output shaft 41 of the reducer respectively. r and F l As a result, the friction surface of the dynamic friction plate 54 contacts the friction surface of the static friction plate 56 and generates relative motion, thereby generating a resistance to the outer drum 3.

[0063] See also Figure 8 , Figure 8 The schematic diagram of the transmission mechanism 5 in the clamping position of the rolling rod 13 according to an embodiment of the present invention is shown. When the rolling rod 13 is clamped, the sector-shaped inner gear 53 rotates counterclockwise, driving the driven gear 52 to rotate through internal meshing, thereby clamping the two rolling rods 13 relative to each other. After the rolling rod 13 is clamped, the sector-shaped inner gear 53 rotates counterclockwise to drive the entire outer drum 3 to rotate counterclockwise.

[0064] See also Fig. 9 , Fig. 9 The schematic diagram of the transmission mechanism 5 in the open position of the rolling rod 13 according to an embodiment of the present invention is shown. When the rolling rod 131 is opened, the sector-shaped inner gear 53 rotates clockwise, driving the driven gear 52 to rotate through internal meshing, thereby causing the two rolling rods 13 to open relative to each other, and when one end of the sector-shaped inner gear 53 contacts the limit pin 23, the entire outer drum 3 is driven to rotate clockwise.

[0065] During operation, when the two rolling leather rods 13 are in the open state (see Figure 7), put the pre-stripped sheepskin between the two opened rolling rods 13; the power output shaft 41 of the reducer rotates counterclockwise, and when the outer drum 3 has a tendency to rotate, the friction plate push plate 55 pushes the dynamic friction plate 54 to press the static friction plate 56, thereby giving the outer drum 3 a resistance opposite to the movement trend, which is greater than the force of the sector-shaped internal gear 53 driving the driven gear 52 to rotate the rolling rod 13 through the driving shaft 11, thereby making the rolling rod 13 located in the clamping position to clamp the sheepskin; when the two rolling rods 13 are clamped, the force that makes the rolling rod 13 continue to rotate is much greater than the friction between the dynamic friction plate 54 and the static friction plate 56. At this time, the front end cover 21 and the transmission mechanism 5 rotate counterclockwise at the same time, rolling the sheepskin and pulling it off. After the sheepskin is pulled off, the power output shaft 41 of the reducer rotates clockwise. When the outer drum 3 tends to rotate, the friction plate push plate 55 pushes the dynamic friction plate 54 to press the static friction plate 56, thereby giving the outer drum 3 a resistance opposite to the movement trend. Since the sheepskin is tightly wrapped around the two leather rolling rods 13, the force of the two leather rolling rods 13 to open is greater than the friction between the dynamic friction plate 54 and the static friction plate 56. The front end cover 21 and the transmission mechanism 5 rotate clockwise at the same time, and the sheepskin begins to unfold from the state of being tightly wrapped around the leather rolling rods 13. When the sheepskin is fully unfolded, the force that rotates the leather rolling rod 13 is less than the friction between the dynamic friction plate 54 and the static friction plate 56. At this time, the two leather rolling rods 13 are in the open position, the sheepskin falls, and a leather pulling process is completed.

[0066] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
