The second rotating rod 608 is rotatably connected to the first circular plate 5. When the staff removes the collecting rod 7, the first electric push rod 607 contracts to allow the arc plate 604 to enter the first sliding groove 603 in the first connecting rod 601, and the arc plate 604 completely disengages from the first sliding groove 603 in the second connecting rod 602, thereby separating the second connecting rod 602 from the first connecting rod 601.

[0023] like Figure 5As shown, the guide assembly 9 includes a first screw rod 901, which is rotatably connected to the two first support plates 1. Two guide rods 902 are arranged on the outer side of the first screw rod 901, and the two guide rods 902 are symmetrically distributed about the center line of the first screw rod 901. A movable plate 903 is sleeved on the outer surface of the first screw rod 901. The movable plate 903 is slidably connected to the two guide rods 902. A limiting plate 904 is fixedly installed on the upper surface of the movable plate 903. A through groove 905 is opened on the side of the limiting plate 904. The terminal material enters the collecting rod 7 through the through groove 905. The first screw rod 901 rotates to make the movable plate 903 move along the axial direction of the guide rod 902, so that the movable plate 903 drives the terminal material in the through groove 905 to move through the limiting plate 904, so that the material is evenly distributed on the surface of the collecting rod 7.

[0024] like Figure 6 As shown, the cutting assembly 11 includes two fixed rods 1101, and the two fixed rods 1101 are fixedly connected to the upper surfaces of the two second support plates 2 respectively. A top plate 1102 is arranged above the fixed rods 1101, and the top plate 1102 is fixedly connected to the two fixed plates. A second slide groove 1103 is opened on the bottom surface of the top plate 1102, and a second screw rod 1104 is rotatably installed on the inner wall of the second slide groove 1103. The outer surface of the second screw rod 1104 is sleeved with a slide plate 1105 corresponding to the second slide groove 1103, and a second electric push rod 1106 is fixedly installed on the bottom surface of the slide plate 1105, and a connecting rod 1106 is fixedly installed on the lower end of the second electric push rod 1106. The connecting plate 1107 has side plates 1108 fixedly installed on both sides of the connecting plate 1107, and the third electric push rod 1109 is fixedly installed on the side where the two side plates 1108 are close to each other. The end of the third electric push rod 1109 is fixedly installed with a first shearing tool 1110. After the terminal material covers the outer surface of the collecting rod 7, the second screw rod 1104 rotates to allow the slide plate 1105 to drive the second electric push rod 1106 to move above the terminal material. The second electric push rod 1106 is unfolded to allow the terminal material to enter the first shearing tool 1110, and the third electric push rod 1109 is unfolded to allow the first shearing tool 1110 to cut the terminal material.

[0025] like Figure 7As shown, the feeding assembly 12 includes a third rotating rod 1201, the third rotating rod 1201 is rotatably connected to the two first support plates 1, a baffle 1202 is fixedly installed on the outer surface of the third rotating rod 1201, a feeding trough 1203 is penetrated inside the baffle 1202, a first rotating groove 1204 and a second rotating groove 1205 connected to the feeding trough 1203 are penetrated on the upper surface of the baffle 1202, the first rotating groove 1204 and the second rotating groove 1205 are along the edge direction of the baffle 1202, and the inner wall of the first rotating groove 1204 is rotatably installed with a third rotating groove 1204. There are three screw rods 1206, and the outer surface of the third screw rod 1206 is sleeved with a second shearing tool 1207 corresponding to the first rotating groove 1204, and the inner wall of the second rotating groove 1205 is rotatably installed with a roller 1208. The paper enters the loading trough 1203 through a plurality of second support rods 14, and the third rotating rod 1201 rotates to make the baffle 1202 correspond to the collecting rod 7, and the roller 1208 rotates to make the paper continue to move. After the paper is spread on the surface of the terminal material, the third screw rod 1206 rotates to make the second shearing tool 1207 shear the paper.

[0026] like Figure 8 As shown, the first shearing tool 1110 is composed of a cutting tool 1111, a buffer plate 1112 and a tool guard plate 1113. The cutting tool 1111 and the tool guard plate 1113 are fixedly connected to the buffer plate 1112 on both sides. The cutting tool 1111 corresponds to the tool guard plate 1113. When the first shearing tool 1110 cuts the terminal material, the two third electric push rods 1109 respectively push the cutting tool 1111 and the tool guard plate 1113 to approach each other, so that the cutting tool 1111 and the tool guard plate 1113 cut the terminal material. At the same time, the buffer plates 1112 on both sides of the cutting tool 1111 and the tool guard plate 1113 are close to each other to fix the terminal material, thereby facilitating the cutting of the terminal material.

[0027] like Figure 7As shown, the material of the roller 1208 is rubber material, and the rubber material has good elasticity and friction. During the movement of the paper, the roller 1208 is in direct contact with the surface of the paper. The rubber roller 1208 can grasp the paper more effectively to prevent the paper from sliding or deflecting during the transportation or winding process, thereby ensuring that the paper can be stably and accurately wound on the terminal. Compared with metal or other hard materials, the rubber material is softer and causes less damage to the surface of the paper roll 13. During the contact and rolling of the paper roll 13 and the roller 1208, the rubber roller 1208 can reduce scratches or damage caused by friction, maintain the integrity of the surface of the paper roll 13, and thus ensure the appearance quality of the terminal after winding. The rubber material also has good wear resistance and anti-aging properties, which can extend the service life of the roller 1208. During long-term and high-frequency use, the rubber roller 1208 can maintain stable performance, reduce the frequency of replacement and maintenance, and reduce the cost of use.

[0028] like Figure 1 As shown, a motor 15 is disposed on the side of the first support plate 1 corresponding to the first screw rod 901 , and the first screw rod 901 is fixedly connected to the output end of the motor 15 , and the motor 15 serves as a power source for the first screw rod 901 .

[0029] like Figure 5 As shown, buffer pads 16 are fixedly installed on both sides of the movable plate 903 corresponding to the two first support plates 1. During the operation of the device, the movable plate 903 needs to be moved frequently to adjust its position and come into contact with the limit plate 904, the paper roll 13 or other components. The soft material of the buffer pad 16 can effectively absorb and disperse the impact force generated during these contacts to avoid hard collisions, thereby protecting the movable plate 903 and the components in contact with it from damage and extending the service life of the equipment. When the movable plate 903 needs to be precisely positioned to cooperate with the winding of the paper roll 13 or the placement of the terminal, the presence of the buffer pad 16 can provide a progressive resistance, so that the movable plate 903 can decelerate smoothly and stop accurately when approaching the target position, which helps to reduce winding deviations or terminal placement errors caused by inaccurate positioning and improve the processing accuracy and consistency of the product.

[0030] Working principle: The terminal material enters the collecting rod 7 through the reversing rod 8, the first support rod 10 and the through slot 905 in the guide assembly 9 in turn. The first screw rod 901 in the guide assembly 9 rotates to make the movable plate 903 move along the axial direction of the guide rod 902, so that the movable plate 903 drives the terminal material in the through slot 905 to move through the limit plate 904, so that the material is evenly distributed on the surface of the collecting rod 7. At the same time, the material in the paper roll 13 enters the collecting rod 7 through several second support rods 14 and the feeding assembly 12 in turn. The roller 1208 in the feeding assembly 12 rotates to make the paper move continuously. Whenever the terminal material fills the collecting rod 7, the roller 1208 in the feeding assembly 12 rotates to move the paper. When the paper fills the terminal material on the collecting rod 7, the third screw rod 1206 rotates to make the second shearing tool 1207 cut the paper The shearing is performed in a reciprocating cycle until the collecting rod 7 is filled with terminal materials. After the terminal materials are filled, the first rotating rod 4 rotates to replace the collecting rod 7. Meanwhile, during the replacement of the collecting rod 7, the second screw rod 1104 rotates to allow the slide 1105 to drive the second electric push rod 1106 to move above the terminal material. The second electric push rod 1106 is unfolded to allow the terminal material to enter the first shearing tool 1110. The third electric push rod 1109 is unfolded to allow the first shearing tool 1110 to cut the terminal material. When the first electric push rod 607 contracts to allow the arc plate 604 to enter the first slide groove 603 in the first connecting rod 601, the arc plate 604 is completely disengaged from the first slide groove 603 in the second connecting rod 602, thereby separating the second connecting rod 602 from the first connecting rod 601. Then the staff removes the collecting rod 7 filled with materials.
