The second adjustment mechanism 33 is connected to the second support member 34, and the expansion shaft 200 can be mounted on the second support member 34. The second adjustment mechanism 33 can adjust the height of the second support member 34, thereby adjusting the height of the expansion shaft 200 mounted on the second support member 34, so that the expansion shaft 200 of different diameters can be located at the central axis position of the material roll 100. The first support member 32 and the second support member 34 are respectively located on the opposite sides of the placement frame 2. After the expansion shaft 200 passes through the material roll 100, the two ends of the expansion shaft 200 can be mounted on the first support member 32 and the second support member 34 respectively, ensuring that the expansion shaft 200 remains balanced and does not press the material roll 100.
[0024] See also Figure 1-4 The push mechanism 4 is installed on the base 1, and the push mechanism 4 is used to push the expansion shaft 200 on the second support member 34 toward the first support member 32 and pass through the material roll 100. In actual use, the material roll 100 is first placed on the placement rack 2, and then the expansion shaft 200 is placed on the second support member 34. At this time, the expansion shaft 200 has not yet contacted the material roll 100 and the first support member 32. Then, the expansion shaft 200 is pushed toward the first support member 32 by the push mechanism 4, and the second support member 34 maintains the state of supporting the expansion shaft 200; after the expansion shaft 200 passes through the material roll 100, the expansion shaft 200 will also move a distance toward the first support member 32 until the expansion shaft 200 contacts the first support member 32, so that the first support member 32 can support the expansion shaft 200, that is, the roll changing work can be completed.
[0025] The present application sets a first support member 32 and a second support member 34 on opposite sides of the placement frame 2, and uses the second adjustment mechanism 33 to adjust the height of the second support member 34. When changing the material rolls 100 with different roll diameters, the staff can adjust the height of the second support member 34 according to the size of the roll diameter of the material roll 100, so that the central axis of the expansion shaft 200 placed on the second support member 34 can coincide with the central axis of the material roll 100, which is convenient for the staff to complete the roll changing work of the material rolls 100 with different roll diameters on one device, reduces the number of equipment used, reduces the factory space, saves production costs, and the overall design of the device has fewer electrical components, is safer, more flexible, and has a wide range of applicability.

When an object is pressed on the first support member 32, the first support member 32 is moved downward by gravity, and the elastic member 312 contracts; when the object pressed on the first support member 32 is removed, the first support member 32 is moved upward and reset under the action of the elastic member 312. The elastic member 312 can be an elastic element such as a spring or rubber. The pad 313 is detachably connected to the main body 311, and the pad 313 is between the first support member 32 and the main body 311. The pad 313 is used to support the first support member 32; when the expansion shaft 200 is pressed on the first support member 32, the first support member 32 will descend. By arranging the pad 313 on the main body 311, the pad 313 limits the descending distance of the support member, ensuring that the central axis of the expansion shaft 200 can be aligned with the central axis of the material roll 100.
[0028] See also Figure 1-5 In actual use, taking the material rolls 100 with 8-inch and 12-inch diameters as examples, when the material roll 100 with 8-inch diameter needs to be replaced, the single-axis trolley 300 transports the material roll 100 with 8-inch diameter to the material roll replacement device, so that the material roll 100 is above the placement rack 2, and the single-axis trolley 300 lowers the material roll 100 to place the material roll 100 on the placement rack 2.

The material shaft 301 of the single-axis trolley 300 is pulled out from the material roll 100, that is, the placement of the material roll 100 with 8-inch diameter is completed, wherein the height of the cushion block 313 can be designed so that the 8-inch material shaft 301 just passes through the material roll 10 with 8-inch diameter. 0; when the material roll 100 with a roll diameter of 12 inches needs to be replaced, the single-axis trolley 300 transports the material roll 100 with a roll diameter of 12 inches to the material roll changing device, so that the material roll 100 is above the placement rack 2, and the staff or the robot removes the pad 313 from the main body 311, and the single-axis trolley 300 lowers the material roll 100, so that the material roll 100 is placed on the placement rack 2. At this time, the material shaft 301 of the single-axis trolley 300 is mounted on the first support member 32, the first support member 32 descends, and the elastic member 312 is compressed and applies elastic force to the first support member 32 until the material roll 100 is stably placed on the placement rack 2, and the material shaft 301 of the single-axis trolley 300 is pulled out from the material roll 100, that is, the placement of the material roll 100 with a roll diameter of 12 inches is completed.

The material roll 100 is transported to the top of the placement rack 2 by the single-axis trolley 300, and the body of the single-axis trolley 300 is located on the side of the first adjustment mechanism 31 away from the second adjustment mechanism 33, and the single-axis trolley 300 lowers the material roll 100.
[0041] For the material rolls 100 with different roll diameters, the single-axle trolley 300 for carrying the material rolls 100 is different. Taking the material rolls 100 with roll diameters of 8 inches and 12 inches as examples, the material roll 100 with a roll diameter of 8 inches corresponds to the single-axle trolley 300 with an 8-inch material shaft 301, and the material roll 100 with a roll diameter of 12 inches corresponds to the single-axle trolley 300 with a 12-inch material shaft 301.
[0042] S02, the first support member 32 descends and makes way for the material shaft 301 of the single-axis trolley 300, or makes the material shaft 301 of the single-axis trolley 300 abut against the first support member 32.
[0043] Take the roll 100 with a roll diameter of 8 inches and 12 inches as an example; when the roll 100 with a roll diameter of 8 inches needs to be replaced, the material shaft 301 of the single-axis trolley 300 descends, so that the material shaft 301 of the single-axis trolley 300 is against the first support member 32, and the cushion block 313 does not need to be removed from the main body 311. At this time, the material roll 100 just rests on the placement rack 2 and the third support member 314; when the roll 100 with a roll diameter of 12 inches needs to be replaced, the staff or the robot first removes the cushion block 313, and the material shaft 301 of the single-axis trolley 300 descends, so that the material shaft 301 of the single-axis trolley 300 is against the first support member 32, and the material shaft 301 of the single-axis trolley 300 continues to press down on the first support member 32, and the elastic member 312 contracts until the material roll 100 rests on the placement rack and the third support member 314.
[0044] S03, the single-axis trolley 300 places the material roll 100 on the placement rack 2, and the single-axis trolley 300 extracts the material shaft 301 from the material roll 100.
[0045] When the 8-inch diameter roll 100 is stably placed on the placement rack 2 and the third support member 314, the single-axis trolley 300 can move in a direction away from the pushing mechanism 4, and the material shaft 301 of the single-axis trolley 300 will be pulled out from the roll 100, that is, the separation of the single-axis trolley 300 and the roll 100 is completed. When the 12-inch diameter roll 100 is stably placed on the placement rack 2 and the third support member 314, the single-axis trolley 300 can move in a direction away from the pushing mechanism 4, and the material shaft 301 of the single-axis trolley 300 will be pulled out from the roll 100, that is, after the separation of the single-axis trolley 300 and the roll 100, the first support member 32 will rebound upward under the action of the elastic member 312, and at this time the staff or the manipulator will put the cushion block 313 back between the first support member 32 and the main body 311.
[0046] S04 , adjusting the height of the second support member 34 according to the size of the expansion shaft 200 , placing the expansion shaft 200 on the second support member 34 , and the pushing mechanism 4 pushes the expansion shaft 200 toward the first support member 32 .
[0047] For the roll change work of the material roll 100 with a roll diameter of 12 inches, the expansion shaft 200 includes a main shaft 201 and an expansion piece 202. The expansion piece 202 is tubular and is sleeved outside the main shaft 201. The diameter of the main shaft 201 is 8 inches, and the diameter of the expansion piece 202 is 12 inches. When the material roll 100 with a roll diameter of 12 inches needs to be changed, the height of the second support member 34 is adjusted by the second adjustment mechanism 33 so that the top of the second support member 34 is flush with the top of the fourth support member 411, and the main shaft 201 is placed between the second support member 34 and the fourth support member 411 by using a handling device. On the fourth support member 411; the expansion shaft 200 is pushed toward the first support member 32 by the pushing mechanism 4. When the expansion member 202 contacts the fixed support member 35, the fixed support member 35 can support the expansion member 202. The pushing mechanism 4 stops pushing the main shaft 201, and then adjusts the height of the second support member 34 through the second adjustment mechanism 33, so that the top of the second support member 34 is flush with or lower than the top of the fixed support member 35, and then the pushing mechanism 4 is used to continue to push the main shaft 201 to move in the direction of the first support member 32.
[0048] For the roll changing work of the material roll 100 with a roll diameter of 8 inches, the diameter of the expansion shaft 200 is 8 inches. When the material roll 100 with a roll diameter of 8 inches needs to be changed, the height of the second support member 34 is adjusted by the second adjustment mechanism 33 so that the top of the second support member 34 is flush with the top of the fourth support member 411, and the expansion shaft 200 is placed on the third support member 314 and the fourth support member 411 by a handling device, and the expansion shaft 200 is pushed toward the first support member 32 by the pushing mechanism 4.
[0049] S05 , passing the expansion shaft 200 through the material roll 100 until one end of the expansion shaft 200 abuts against the first support member 32 , so that the first support member 32 supports one end of the expansion shaft 200 .
[0050] After completing the roll changing work of the material roll 100, the pushing frame 41 can be pushed toward the end of the second guide rail 12 away from the placement frame 2 to align the second socket with the first socket, and then the pin 43 is inserted into the second socket to complete the resetting of the pushing mechanism 4.
[0051] It can be seen from this embodiment that when changing rolls 100 of different diameters, the staff can adjust the height of the second support member 34 according to the size of the diameter of the roll 100, so that the central axis of the expansion shaft 200 placed on the second support member 34 can coincide with the central axis of the roll 100, which makes it convenient for the staff to complete the roll changing work of the rolls 100 of different diameters on one device, reduces the number of equipment used, reduces the factory floor space, saves production costs, and has high flexibility and a wide range of applicability.
