[0048] like Figure 1 to Figure 5 As shown, the membrane roll changing device provided in this embodiment includes a bracket 1, a rotating disk 2, a first rod 3 and a second rod 4.

[0049] The rotating disk 2 is rotatably connected to the bracket 1, and the rotating disk 2 can rotate from the first position to the second position. The rotating disk 2 in the first position and the second position can be relatively fixed to the bracket 1. The first rod 3 and the second rod 4 are fixedly connected to the rotating disk 2, and the first rod 3 and the second rod 4 extend along the rotation axis direction of the rotating disk 2 toward the side away from the bracket 1. One end of the first rod 3 away from the rotating disk 2 and one end of the second rod 4 away from the rotating disk 2 can alternately abut and align with one end of the winding shaft 100 of the slitting machine, and the winding core 210 of the diaphragm roll 200 can be sleeved on the first rod 3, the second rod 4 and the winding shaft 100.

[0050] In specific implementation, after the slitting machine completes a work process, the diaphragm roll changing device is first moved as a whole to the unloading position of the winding shaft 100. Initially, the rotating disk 2 is located at the first position and is relatively fixed between the bracket 1. The bracket 1 is moved so that one end of the first rod 3 abuts and is centered with the winding shaft 100. At this time, the operator can use the first rod 3 and the winding shaft 100 that abut and are centered with each other to move the finished diaphragm roll 200 on the winding shaft 100 to the first rod 3 at one time; after the transfer of the finished diaphragm roll 200 is completed, the bracket 1 is moved in the opposite direction to separate the first rod 3 and the winding shaft 100, and then the fixing between the rotating disk 2 and the bracket 1 is released. , rotate the rotating disk 2 to the second position, and make the rotating disk 2 at the second position relatively fixed. At this time, move the bracket 1 again to the side close to the winding shaft 100, so that one end of the second rod 4 abuts and aligns with the winding shaft 100. The operator can use the second rod 4 and the winding shaft 100 that abut and align with each other to move the empty winding core 210 pre-set on the second rod 4 to the winding shaft 100 at one time. After the empty winding core 210 is transferred, move the bracket 1 to separate the second rod 4 and the winding shaft 100. At this point, the roll changing operation is completed, and the slitting machine can continue the next work process.

[0051] The diaphragm roll changing device provided in this embodiment can achieve one-time removal of the finished diaphragm roll 200 from the winding shaft 100 and one-time replacement of the empty roll core 210 onto the winding shaft 100 by alternately abutting and aligning the first rod 3 and the second rod 4 on the rotating disk 2. The roll changing operation is simple and quick, and there is no need for manual handling and replacement one by one, which is beneficial to reducing manual labor intensity and improving production efficiency.

[0052] In some embodiments, when the rotating disk 2 rotates from the first position to the second position, the position of the first rod 3 and the position of the second rod 4 are interchanged. Such an arrangement not only facilitates the positioning of the first rod 3 and the second rod 4 on the rotating disk 2 during design and manufacturing; at the same time, since the position of the first rod 3 and the second rod 4 will be interchanged with each other as the rotating disk 2 rotates, it is only necessary to move the bracket 1 when the rotating disk 2 is in the first position so that one end of the first rod 3 is centered with the winding shaft 100, and when the rotating disk 2 rotates from the first position to the second position, the second rod 4 will directly rotate to a position centered with the winding shaft 100, without the need for the user to perform centering adjustment, which is conducive to improving the overall production efficiency.

[0053] Optionally, the outer diameter of the first rod 3 and the outer diameter of the second rod 4 are equal to the outer diameter of the winding shaft 100 to ensure that the winding core 210 can smoothly move between the first rod 3 and the winding shaft 100 and between the second rod 4 and the winding shaft 100 .

[0054] like Figure 4 and Figure 5As shown, in some embodiments, a clamping groove 5 is provided at one end of the first rod 3 and the second rod 4 away from the rotating disk 2, and a clamping protrusion 6 is provided at one end of the winding shaft 100, and the clamping protrusion 6 can be mutually clamped with the clamping groove 5. Such a configuration can improve the stability of the first rod 3, the second rod 4 and the winding shaft 100 when they are abutted and aligned, thereby ensuring the smooth progress of the roll changing operation.

[0055] Optionally, the clamping groove 5 can be integrally formed with the first rod 3 and the second rod 4 , and the clamping protrusion 6 can be integrally formed with the winding shaft 100 .

[0056] like Figure 1 As shown, in some embodiments, the rotating disk 2 is relatively fixed to the bracket 1 through the positioning pin 7, and the positioning pin 7 passes through the rotating disk 2 and is connected to the bracket 1. Specifically, a back plate can be provided on the bracket 1, and a positioning hole is provided on the back plate, and the positioning pin 7 is configured to be connected to the positioning hole. In this way, when the rotating disk 2 needs to be kept relatively fixed, the positioning pin 7 is inserted, and when the rotating disk 2 needs to be rotated, the positioning pin 7 is pulled out to release the connection between the rotating disk 2 and the bracket 1. The positioning pin 7 has a simple structure, is easy to operate, and has a low manufacturing cost.

[0057] Furthermore, the positioning pin 7 is a rotary plunger reset type positioning pin. In this way, after the positioning pin 7 is pulled out, the head of the rotary plunger reset type positioning pin retracts and releases the connection with the bracket 1. After the rotating disk 2 rotates to the right position, it is only necessary to release the positioning pin 7. The head of the rotary plunger reset type positioning pin can automatically reset under the elastic force of the internal spring, and the connection between the positioning pin 7 and the bracket 1 is automatically realized. The rotary plunger reset type positioning pin is a mature prior art in the field and will not be described in detail here.

[0058] Alternatively, if Figure 1 As shown, the number of the positioning pins 7 can be set to two, and the two positioning pins 7 are located on the same circumference.

[0059] like Figure 1 As shown, in some embodiments, the rotation axis of the rotating disk 2 is set at the center of the rotating disk 2, and the first rod 3 and the second rod 4 are symmetrically arranged on opposite sides of the rotating disk 2 relative to the central axis of the rotating disk 2. When the rotating disk 2 rotates 180°, the position of the first rod 3 and the position of the second rod 4 are exchanged.

[0060] Through such an arrangement, the rotation axis of the rotating disk 2 is located at its center, ensuring that the rotating disk 2 rotates around its central axis, and the symmetrical arrangement of the first rod 3 and the second rod 4 helps to balance the force of the rotating disk 2 during rotation, making the operation smoother.

[0061] like Figure 1As shown, in some embodiments, the rotating disk 2 is rectangular, and when the rotating disk 2 is in the first position and the second position, the long side of the rotating disk 2 extends in the vertical direction, the number of the first rods 3 is multiple, and the multiple first rods 3 are arranged at intervals along the long side direction of the rotating disk 2, and the number of the second rods 4 is multiple, and the multiple second rods 4 correspond to the multiple first rods 3 one by one. At this time, the multiple first rods 3 and the multiple second rods 4 are symmetrically arranged along the short side of the rectangle.

[0062] Through such an arrangement, the plurality of first rods 3 and the plurality of second rods 4 can be suitable for a slitting machine having a plurality of winding shafts 100, thereby increasing the number of diaphragm rolls 200 and winding cores 210 that can be replaced at one time, and further improving production efficiency.

[0063] Specifically, Figure 2 As shown, in this embodiment, the slitting machine has two winding shafts 100 spaced apart from each other, and correspondingly, two first rods 3 and two second rods 4 are respectively arranged at intervals in the vertical direction, and the two first rods 3 and the two second rods 4 are symmetrically arranged along the rectangular short side direction of the rotating disk 2. However, it is not limited to this. In other embodiments, for example, the slitting machine can have three winding shafts 100 spaced apart from each other, and correspondingly, three first rods 3 and two second rods 4 are respectively arranged at intervals in the vertical direction. Alternatively, multiple winding shafts 100 can also be arranged horizontally, in which case, multiple first rods 3 and multiple second rods 4 are also arranged horizontally accordingly. That is: the number and arrangement of the first rods 3 and the second rods 4 can be determined according to the different conditions of the winding shaft 100 of the corresponding slitting machine, as long as the first rods 3 and the second rods 4 can alternately abut and center the winding shaft 100.

[0064] In some embodiments, the bracket 1 includes a connecting portion and a main body portion, the rotating disk 2 is rotatably connected to the main body portion, and the main body portion can move up and down relative to the connecting portion to drive the first rod 3 and the second rod 4 on the rotating disk 2 to move up and down, so that the first rod 3 and the second rod 4 can adapt to the different heights of the winding shaft 100 of different models of slitting machines. Specifically, the main body portion can be driven to move in the vertical direction along the connecting portion by setting a driving motor or the like.

[0065] Further optionally, a rotating bearing 9 is provided between the rotating disk 2 and the main body, the fixed end of the rotating bearing 9 is mounted on the main body, and the rotating end is mounted on the rotating disk 2, so as to provide a more stable rotation effect for the rotating disk 2.

[0066] like Figure 1 As shown, in some embodiments, a plurality of handles 21 are provided at intervals along the circumference of the rotating disk 2. The handles 21 can provide a gripping position when the rotating disk 2 rotates.

[0067] In other embodiments, a rotary drive member may be provided for the rotary disk 2, the rotary drive member being fixedly mounted on the bracket 1, and the output shaft of the rotary drive member being connected to the rotary disk 2 for driving the rotary disk 2 to rotate, thereby replacing manual rotation. For example, the rotary drive member may be an electric motor, a pneumatic motor, etc., which are not specifically limited here.

[0068] like Figure 1 and Figure 2 As shown, in some embodiments, the diaphragm roll changing device further comprises a base 8. A guide rail 81 is fixedly connected to the base 8, and the extension direction of the guide rail 81 is parallel to the length direction of the first rod 3 and the second rod 4, and the bracket 1 is slidably connected to the guide rail 81. That is, the bracket 1 can approach or move away from the winding shaft 100 through the guide rail 81.

[0069] Through such an arrangement, the contact or separation of the first rod 3 and the second rod 4 with the winding shaft 100 can be controlled more conveniently and accurately.

[0070] Furthermore, if Figure 3 As shown, the two opposite ends of the guide rail 81 are provided with limit members 811, and the limit members 811 are configured to stop the bracket 1. With such arrangement, the limit members 811 can effectively prevent the bracket 1 from coming off the guide rail 81, which is beneficial to improving the reliability of the device.

[0071] Specifically, the limiting member 811 is a limiting block.

[0072] Optionally, a sliding drive member is provided on the base 8, and an output shaft of the sliding drive member is connected to the bracket 1 to drive the bracket 1 to slide along the guide rail 81. Exemplarily, the sliding drive member can be a linear motor, a hydraulic cylinder, etc., which is not specifically limited here.

[0073] like Figure 1 As shown, in some embodiments, a universal wheel 82 is provided at the bottom of the base 8. Specifically, four universal wheels 82 are provided on the base 8. The provision of the universal wheels 82 facilitates the movement of the membrane roll changing device as a whole.

[0074] Furthermore, the universal wheel 82 has a braking function to keep the entire device in a stable state after the diaphragm roll changing device moves into place.

[0075] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
