Moreover, the specific features, structures, materials or characteristics described can be combined in any appropriate manner in one or more embodiments or examples.
[0050] With reference to Figures 1 to 3 According to the first aspect of the present application, the roll changing device comprises a cutting roller module 100, a mounting seat 200 and a brake 300. The cutting roller module 100 comprises a barrel 110 and a cutting knife 130. The barrel 110 is mounted on the mounting seat 200, and a first outer circumferential surface 111 of the barrel 110 is used to abut against a material tape 700. The cutting knife 130 is mounted on the mounting seat 200.
[0051] The first driving assembly 400 is used to drive the cutting knife 130 to move relative to the mounting seat 200, so that the cutting knife 130 moves to a set position. The cutting knife 130 located at the set position is used to cut the material tape 700 attached to the first outer circumferential surface 111. The brake 300 is connected with the mounting seat 200 and the cutting knife 130. When the cutting knife 130 is located at the set position, the brake 300 is used to stop the movement of the cutting knife 130 relative to the mounting seat 200.
[0052] According to the roll changing device of the present application, at least the following beneficial effects are achieved: After the first driving assembly 400 moves the cutting knife 130 to the set position, the cutting knife 130 is kept at the set position by the brake 300, so that the position of the cutting knife 130 can be accurately controlled.
[0053] Specifically, the first driving assembly 400 is used to drive the cutting knife 130 to move relative to the mounting seat 200. It can be that the cutting knife 130 rotates around the barrel 110, or the barrel 110 is rotationally connected with the mounting seat 200, and the first driving assembly 400 drives the barrel 110 to move relative to the mounting seat 200, while the cutting knife 130 rotates synchronously with the barrel 110.
[0054] It should be noted that the cutting knife 130 moved to the set position can directly cut the material tape 700, or the cutting knife 130 moved to the set position needs additional movement to cut the material tape 700.
[0055] With reference to Figure 1In some embodiments of the present application, the cylinder 110 is rotatably connected to the mounting base 200, and the cutter 130 is mounted on the cylinder 110. The first driving assembly 400 is configured to drive the cylinder 110 to rotate relative to the mounting base 200, so as to drive the cutter 130 to rotate to a set position. The brake 300 is connected to the mounting base 200 and the cylinder 110, and is configured to stop the rotation of the cylinder 110 relative to the mounting base 200 when the cutter 130 is located at the set position.
[0056] By mounting the cutter 130 on the cylinder 110, the cutter 130 and the cylinder 110 are structurally connected together, and the cutter 130 does not need to be separately mounted, thereby saving installation space and simplifying the structure of the roll changing device. By driving the cutter 130 to rotate through the first driving assembly 400, the cutter 130 can cut the material tape 700 attached to the set position of the first outer circumferential surface 111, and the position control of the cutter 130 is accurate and flexible.
[0057] It should be noted that the roll changing device will pull the material tape 700 to one of two or more winding shafts, and therefore the set position is generally two or more, for example, the set position includes a first position, a second position and a third position, and the first position, the second position and the third position are distributed along the circumference of the cylinder 110.
[0058] With reference to Figure 1 In the improved scheme of the above embodiment, the cutter 130 is fixed to the cylinder 110.
[0059] By fixing the cutter 130 to the cylinder 110, the structure of the cutter roller module is simpler, thereby facilitating the reduction of the production cost of the roll changing device.
[0060] It should be noted that by fixing the cutter 130 to the cylinder 110, the rotation of the cylinder 110 not only realizes the adjustment of the set position of the cutter 130, but also realizes the cutting of the material tape 700 by the cutter 130.
[0061] With reference to Figure 3 In the improved scheme of the above embodiment, the cutter roller module 100 further includes a second driving assembly 120, and the second driving assembly 120 is configured to drive the cutter 130 located at the set position to move relative to the cylinder 110, so as to cut the material tape 700 attached to the first outer circumferential surface 111.
[0062] By providing the second driving assembly 120, the movement of the cutter 130 to cut the material tape 700 can be separately controlled, and the cutting movement control of the cutter 130 is more flexible.
[0063] With reference to Figure 3In the improved scheme of the above embodiment, the second driving assembly 120 is configured to drive the cutter 130 at the set position to move along the axial direction of the cylinder 110 to cut the material strip 700 attached to the first outer circumferential surface 111.
[0064] By moving the cutter 130 along the axial direction of the cylinder 110, the material strip 700 attached to the first outer circumferential surface 111 can be smoothly and completely cut.
[0065] Specifically, the second driving assembly 120 can be one of a pneumatic cylinder, a linear motor, a motor-driven crank slider mechanism, a motor-driven rack and pinion mechanism, a motor-driven lead screw and nut mechanism, and a motor-driven chain and sprocket mechanism. The cylinder 110 is provided with a receiving hole 112 and a slit 113, the slit 113 is in communication with the receiving hole 112, and the slit 113 penetrates through the first outer circumferential surface 111. The second driving assembly 120 is arranged in the receiving hole 112, and the cutter 130 extends out of the slit 113. The second driving assembly 120 drives the cutter 130 to move along the axial direction of the cylinder 110, i.e. to cut the material strip 700.
[0066] Referring to Figure 4 In the improved scheme of the above embodiment, the second driving assembly 120 is configured to drive the cutter 130 at the set position to move along the radial direction of the cylinder 110 to cut the material strip 700 attached to the first outer circumferential surface 111.
[0067] By moving the cutter 130 along the radial direction of the cylinder 110, the material strip 700 attached to the first outer circumferential surface 111 can be smoothly and completely cut.
[0068] Specifically, the second driving assembly 120 can be one of a pneumatic cylinder, a linear motor, a motor-driven crank slider mechanism, a motor-driven rack and pinion mechanism, a motor-driven lead screw and nut mechanism, and a motor-driven chain and sprocket mechanism.
[0069] The cylinder 110 is provided with a receiving hole 112 and a slit 113, the slit 113 is in communication with the receiving hole 112, and the slit 113 penetrates through the first outer circumferential surface 111. The second driving assembly 120 is arranged in the receiving hole 112, and the cutter 130 extends out of the slit 113. The second driving assembly 120 drives the cutter 130 to move along the axial direction of the cylinder 110, i.e. to cut the material strip 700.
[0070] Referring to Figure 5 In some embodiments of the present application, the first driving assembly 400 includes a first motor 410 and a position sensor 420. The first motor 410 is configured to drive the cutter 130 to rotate relative to the mounting base 200. The position sensor 420 is configured to detect the rotational position of the cutter 130 relative to the mounting base 200.
[0071] The rotation position of the cutter 130 relative to the mounting seat 200 is detected by the position sensor 420, which is advantageous for accurately feeding back the position of the cutter 130, and thus making the cutter 130 accurately move to the set position.
[0072] In another embodiment, the first motor 410 can also be replaced by a hydraulic motor or a pneumatic motor.
[0073] With reference to Figure 5 In the improved scheme of the above embodiment, the position sensor 420 comprises one of an encoder, a Hall effect sensor and a rotary transformer.
[0074] The encoder, the Hall effect sensor and the rotary transformer are easy to obtain, which is advantageous for reducing the production cost of the roll changing device.
[0075] With reference to Figure 5 In the improved scheme of the above embodiment, the brake 300 comprises one of a mechanical brake, a hydraulic brake, a pneumatic brake and an electromagnetic brake.
[0076] The mechanical brake, the hydraulic brake, the pneumatic brake and the electromagnetic brake are easy to obtain, which is advantageous for reducing the production cost of the roll changing device.
[0077] With reference to Figure 1 In some embodiments of the present application, the axial direction of the cylinder body 110 is defined as the first direction, the second direction is defined as the angle between the first direction and the second direction is greater than zero, the second axis is parallel to the first axis of the cylinder body 110, and the roll changing device further comprises a third driving assembly 520, a fourth driving assembly 510 and a fifth driving assembly 530.

The fourth driving assembly 510 is used to drive the mounting seat 200 to move along the second direction. The fifth driving assembly 530 is used to drive the mounting seat 200 to rotate around the second axis.
[0078] By setting the third driving assembly 520, the fourth driving assembly 510 and the fifth driving assembly 530, the position of the cylinder body 110 in the three-dimensional space can be flexibly controlled, and thus the material belt 700 can be conveniently pulled from one winding shaft to another winding shaft.
[0079] Specifically, the angle between the second direction and the first direction can be 30 degrees, 45 degrees, 60 degrees or 90 degrees, wherein 90 degrees is a preferred embodiment. For example, with reference to Figure 1 The first direction is the left-right direction, and the second direction is the front-back direction.
[0080] It should be noted that the third driving assembly 520 drives the cylinder 110 to move in the second direction, and the fifth driving assembly 530 drives the cylinder 110 to rotate around the second axis, so as to drive the material belt 700 attached to the cylinder 110 to move from one winding shaft to another winding shaft.

The third driving assembly 520, the fourth driving assembly 510 and the fifth driving assembly 530 jointly constitute the driving module 500.
