The pre-laminating mechanism 1 comprises a contoured hot pressing head 16, and a pressing portion 161 is provided on the contoured hot pressing head 16. The pressing portion 161 is set to a size corresponding to the middle position of the cylindrical piece 10 so as to be used for pre-laminating a leather material 20 at the middle position of the cylindrical piece 10. The size of the leather material 20 is set to correspond to the outer surface of the cylindrical piece 10. The leather material 20 has a length direction a and a width direction b. The length direction a corresponds to the circumference of the cylindrical piece 10, and the width direction b corresponds to the axial direction of the cylindrical piece 10. The leather material 20 has a middle area 202 in the length direction a, and the middle area 202 is set to correspond to the middle position of the cylindrical piece 10; the roller skinning mechanism 2 comprises a roller 27 and a mounting shaft 25 arranged side by side in a horizontal direction. The roller skinning mechanism 2 also comprises a rotating portion 29 for driving the mounting shaft 25 to rotate along its own axial direction. The mounting shaft 25 is used to The cylinder 10 with the leather material 20 attached to the middle position is detachably fixed and cooperates with the roller 27 under the drive of the rotating part 29 to attach the leather material 20 to the cylinder 10; a stopper is also provided on the roller leather-sticking mechanism 2, which determines the rotation range of the rotating part 29 so as to leave a first reserved area 203 and a second reserved area 204 that are not adhered to the cylinder 10 at the two end edges in the length direction a of the leather material 20; the pressing mechanism 3 includes an upper mold 33 and a lower mold 32 that cooperate with each other, the lower mold 32 is used to install the cylinder 10 and to fit with the outer surfaces of the first reserved area 203 and the second reserved area 204, and the upper mold 33 provides pressure during the descending movement to be used for hot pressing the first reserved area 203 and the second reserved area 204 to the cylinder 10 at the same time and to splice the edges of the first reserved area 203 and the second reserved area 204 at the same time to form a leather material 20 without a splicing seam attached to the cylinder 10. Specifically, the cylinder 10 can be made of plastic material, and the cylinder 10 is a hollow through structure. The leather 20 can be made of PU material.

For the situation where the leather 20 needs to be attached to the outer surface of the cylinder 10, any section of the circumference of the cylinder 10 and the area extending to the two ends of the cylinder 10 in the axial direction can be selected as the middle position. When a non-attachment area is provided on the cylinder 10, such as Figure 2As shown, for example, the non-attachment area is the button area 101, and the non-attachment area only occupies a part of the area in the axial direction of the cylinder 10, the button area 101 does not need to be attached to the leather material 20, and the leather material 10 is provided with an avoidance recess 201 for avoiding the non-attachment area. At this time, the position opposite to the non-attachment area can be used as the middle position, so that the two ends of the leather material 20 are correspondingly attached to the peripheral side of the non-attachment area, and the attachment is more convenient. The width of the middle area 202 in the length direction a of the leather material 20 accounts for 8% to 15% of the total length of the leather material 20 in the length direction a. Figure 3 As shown, the width of the middle area in the length direction of the leather material 20 is a first width w1 , and the first width w1 accounts for 8% to 15% of the total length of the leather material 20 in the length direction a.

The pressing portion 161 is arc-shaped, and the size of the pressing portion 161 corresponds to the size of the middle position of the cylinder 10 to evenly attach the leather material 20 to the middle position of the cylinder 10. The connection structure of the cylinder 10 and the leather material 20 after pre-lamination by the pre-lamination mechanism 1 is shown in Figure 7 As shown, at this time, the support film 30 has been torn off.

Specifically, as Figures 8 to 12 As shown, when the cylinder member 10 is installed, the middle position of the cylinder member 10 is set toward the direction of the roller 27 and the cylinder member 10 is fixed on the installation shaft 25. The slide block 26 is pushed to move along the slide rail 23 toward the installation shaft 25 through the action port 242 of the handle member 24 and the action column 261 so that the leather material 20 connected to the middle position of the cylinder member 10 is located between the cylinder member 10 and the roller 27 and is pressed and connected to each other. The rotation of the installation shaft 25 drives the cylinder member 10 to rotate. During the rotation of the cylinder member 10, since the cylinder member 10, the leather material 20 and the roller 27 are pressed and connected, the cylinder member 10 drives the roller 27 to rotate, thereby attaching the leather material 20 to the outer surface of the cylinder member 10. A hand crank handle 291 is also specifically provided on the rotating part 29, and the installation shaft 25 is driven to rotate by moving the hand crank handle 291.

A first through hole is provided on the slider 26 along the arrangement direction of the roller 27 and the mounting shaft 25, and the first through hole includes a first sub-hole 262 and a second sub-hole 263. The aperture of the first sub-hole 262 is smaller than the aperture of the second sub-hole 263 so that a first step surface 264 is formed between the first sub-hole 262 and the second sub-hole 263. A stud is fixedly connected in the first through hole, and the stud extends from the first sub-hole 262 to the second sub-hole 263 and extends out of the slider 26. A matching hole is provided on the connecting seat 28 corresponding to the stud, and the stud extends into the matching hole. A first elastic member 265 is also provided between the first step surface 264 and the connecting seat 28. A positioning pin 266 is also provided on the connecting seat 28, and the positioning pin 266 extends toward the slider 26 and extends out from the slider 26, and the positioning pin 266 is slidably connected to the slider 26.

Figure 3 As shown, the width of the first reserved area 203 in the length direction of the leather 20 is the second width w2, and the width of the second reserved area 204 in the length direction of the leather 20 is the third width w3. The setting of the second width w2 and the third width w2 ensures that the leather 20 is attached to most areas of the cylinder 10 after the roller skinning mechanism 2, so that the yield of skinning is higher and it is less likely to produce seams.
