[0032] Reference Figure 2-Figure 4 A driving unit is provided on the left side of the paper feeding roller 4, and the driving unit includes a motor 41. The motor 41 is fixedly connected to the left surface of the frame 1, and the right output end of the motor 41 runs through the frame 1. The right output end of the motor 41 is fixedly connected to a rotating rod 42. When the motor 41 is started, it can drive the rotating rod 42 to rotate. A slot 43 is provided on the right surface of the rotating rod 42. The limiting column 5 on the left side of the paper feeding roller 4 is plugged into the inside of the slot 43. After the limiting column 5 on the left side enters the inside of the slot 43, it can be quickly limited by the limiting unit. At this time, when the motor 41 is started, it can drive the limiting column 5 and the paper feeding roller 4 to rotate, and release the drawing.

[0033] An electric push rod 6 is fixedly connected to the right inner wall surface of the frame 1, and the left end of the electric push rod 6 is fixedly connected to the limit plate 7. When the electric push rod 6 is started, it can drive the limit plate 7 to perform linear motion in the left and right directions. A guide rod 71 is fixedly connected to the right surface of the limit plate 7. The right end of the guide rod 71 passes through the frame 1, and the guide rod 71 is plugged into the frame 1. The movement of the limit plate 7 can be guided and limited by the set guide rod 71, so that the limit plate 7 can only perform linear motion in the left and right directions, avoiding deviation and affecting the support and limit of the paper feed roller 4. The interior of the limit plate 7 is fixedly connected to a bearing 8, and the limit column 5 located on the right side of the paper feed roller 4 is plugged into the interior of the bearing 8.

[0034] When the limiting post 5 on the left is inserted into the slot 43, the electric push rod 6 can be started to drive the limiting plate 7 to move left, so that the limiting post 5 on the right is inserted into the bearing 8. At this time, the bearing 8 and the limiting plate 7 can support and limit the right end of the paper feed roller 4. At the same time, when the paper feed roller 4 rotates, the bearing 8 can be driven to rotate by the limiting post 5 on the right, which can reduce the friction resistance from the right side when the paper feed roller 4 rotates and extend the service life of the device.

[0035] Reference Figure 2 and Figure 4 , a limiting unit is provided on the left side of the paper feed roller 4, and the limiting unit includes a fixing frame 91, which is fixedly connected to the upper end of the rotating rod 42, and a round block 92 is provided above the fixing frame 91. The bottom surface of the round block 92 is fixedly connected to the insertion rod 93. When the round block 92 moves, it can drive the insertion rod 93 to move synchronously. The bottom end of the insertion rod 93 passes through the fixing frame 91 and the rotating rod 42. The insertion rod 93 is plugged into the fixing frame 91 and the rotating rod 42, and the movement of the insertion rod 93 can be guided and limited, so that the insertion rod 93 can only move linearly in the up and down directions. The outer side of the insertion rod 93 is provided with a spring 94 The bottom end of the spring 94 is fixedly connected to the upper surface of the fixing frame 91, and the top end of the spring 94 is fixedly connected to the bottom surface of the round block 92. When the round block 92 moves up, it will pull the spring 94, causing the spring 94 to stretch and generate elastic potential energy. A round hole 95 is provided on the upper surface of the limiting column 5 on the left side of the paper feed roller 4, and the bottom end of the insertion rod 93 is plugged into the inside of the round hole 95. After the insertion rod 93 is inserted into the inside of the round hole 95, the limiting column 5 on the left side can be limited and fixed, so that the paper feed roller 4 can rotate synchronously with the rotating rod 42, and at the same time, the paper feed roller 4 can be prevented from separating from the rotating rod 42.

[0036] Working principle: When replacing the paper roll on the outside of the paper feed roller 4, start the electric push rod 6 to drive the limit plate 7 to move right, and then drive the bearing 8 to leave the limit column 5 on the right side. After quickly releasing the limit on the right side of the paper feed roller 4, pull up the round block 92 to drive the insertion rod 93 to move upward. After releasing the limit on the left side of the paper feed roller 4, directly pull the paper feed roller 4 to the right, and the paper feed roller 4 together with the remaining paper tubes can be removed from the inside of the frame 1 for replacement, which can reduce the space required for the plotter and improve the adaptability of the plotter. At the same time, the paper roll can be quickly replaced to improve the plotting efficiency of the plotter. After inserting the new paper roll to the outside of the paper feed roller 4, reverse the above steps to quickly complete the replacement of the new paper roll. The operation is easy.
