Description

Technical Field

[0001] This utility model relates to the field of feeding roller technology, specifically to a feeding roller that can be quickly disassembled. Background Technology

[0002] Currently, in the process of packaging the core electrode, a transparent plastic roll (soft, white, transparent plastic) is required on the feed roller. When the transparent plastic roll on the feed roller is used up, it is often necessary to remove multiple bolts to replace the feed roller containing the plastic roll (to ensure that the transparent plastic roll is in the designated position on the feed roller, thus ensuring the packaging qualification rate). This operation is time-consuming and labor-intensive, reducing the efficiency of replacing the feed roller. In addition, in order to quickly load the plastic roll onto the feed roller, an air shaft is often used. However, the use of an air shaft requires the arrangement of air passages, which increases the complexity of the equipment and brings a poor user experience. Utility Model Content

[0030] Please see Figures 1-7 This application provides a technical solution: a quick-detachable feeding roller disc, including a connecting shaft 110, a connector 120, a hollow roller 130, a locking mechanism 140, a tensioning mechanism 150, and a limiting mechanism 160. One end of the connecting shaft 110 is fixed to one end of the connector 120 by a flange, and one end of the hollow roller 130 is inserted into the other end of the connector 120. It also includes a limiting plate 170, which is threaded onto the roller shaft of the hollow roller 130. In this embodiment, the connecting shaft 110 is installed on the output shaft of the feeding motor.

[0031] A locking mechanism 140 is installed on the roller shafts of the connector 120 and the hollow roller 130. The locking mechanism 140 is used to quickly attach the hollow roller 130 to the connector 120 or to quickly disassemble the hollow roller 130. The locking mechanism 140 includes a first spring 142, a U-shaped rod 143, a second spring 144, and a Z-shaped plate 145. A countersunk hole 141 is provided on the connector 120, and one end of the first spring 142 is fixed in the countersunk hole 141. Inside, the other end of the first spring 142 is fixed to the U-shaped rod 143. The U-shaped rod 143 slides through the countersunk hole 141. The end of the U-shaped rod 143 is inserted into the roller shaft of the hollow roller 130. The Z-shaped plate 145 is fixed to the other end of the U-shaped rod 143. The second spring 144 is fixed between the two Z-shaped plates 145. The roller shaft of the hollow roller 130 is provided with a positioning groove 146. The end of the U-shaped rod 143 is inserted into the positioning groove 146.

[0032] The tensioning mechanism 150 is mounted on the hollow roller 130. The tensioning mechanism 150 is used to quickly fix the material cylinder onto the hollow roller 130. The tensioning mechanism 150 includes a guide sleeve 151, a third spring 152, a limiting block 154, a lead screw 155, a frustum block 156, a nut 157, and a guide block 158. The lead screw 155 is rotatably disposed inside the hollow roller 130. The frustum block 156 is sleeved on the lead screw 155. The nut 157 is fixed to the outer wall of the frustum block 156 and threaded onto the lead screw 155. One end of the guide block 158 is fixed. On the outer wall of the nut 157, the other end of the guide block 158 is slidably disposed inside the hollow roller 130. The guide sleeve 151 is sleeved on the frustum block 156. The limiting block 154 is fixed on the outer wall of the guide sleeve 151. The limiting block 154 slides through the hollow roller 130. A third spring 152 is fixedly installed between the two corresponding guide sleeves 151. A first through hole 153 is opened on the hollow roller 130. The limiting block 154 passes through the first through hole 153. A limiting groove 159 is opened inside the hollow roller 130. One end of the guide block 158 is slidably disposed on the limiting groove 159.

[0033] The limiting mechanism 160 is installed on the lead screw 155. The limiting mechanism 160 is set to limit and fix the lead screw 155. The limiting mechanism 160 includes a disc 161 and a locking member 162. The disc 161 is fixed on the outer wall of the lead screw 155. The locking member 162 is threaded through the disc 161. The locking member 162 and the hollow roller 130 are correspondingly arranged.

[0034] The working principle and process of this utility model are as follows: When the used material cylinder needs to be replaced, push the Z-shaped plate 145 to move the two Z-shaped plates 145 away from each other, causing the end of the U-shaped rod 143 to leave the positioning groove 146. Then, the hollow roller 130 can be removed. Rotate the limiting plate 170, which is close to the connector 120, and remove the limiting plate 170. Then, rotate the locking member 162 to move the end of the locking member 162 away from the hollow roller 130. Finally, rotate the disc 161 to control its rotation. The reverse rotation moves the frustum block 156 away from the guide sleeve 151. Under the reaction of the third spring 152, the corresponding two guide sleeves 151 come into contact, thus allowing the limiting block 154 to enter the first through hole 153, releasing the constraint on the material cylinder. The empty material cylinder is then removed from the hollow roller 130, and the material cylinder containing the plastic roll is placed at the designated position on the hollow roller 130. Then, the disc 161 is rotated in the reverse direction, causing the frustum block 156 to enter the guide sleeve 151. The frustum block 156, guide sleeve 151, and guide block 154 then interact. Under the combined action of 58 and nut 157, the limiting block 154 protrudes from the hollow roller 130 and presses against the inner wall of the material cylinder, fixing the material cylinder onto the hollow roller 130. Then, the locking member 162 rotates in the opposite direction, and its end presses against the outer wall of the hollow roller 130, fixing the lead screw 155 inside the hollow roller 130. Afterwards, the removed limiting plate 170 is reinstalled onto the hollow roller 130. Then, the Z-shaped plate 145 is pushed, causing the end of the U-shaped rod 143 to enter the countersunk hole 141. Finally, the hollow roller... The roller shaft of 130 is inserted into the connector 120. The Z-shaped plate 145 is released. Under the reaction action of the second spring 144 and the first spring 142, the end of the U-shaped rod 143 is inserted into the positioning groove 146, realizing the quick assembly of the hollow roller 130 onto the connector 120. This quick-detachable feeding roller disc facilitates the quick installation and removal of the hollow roller 130, saving time and effort and improving the replacement efficiency of the hollow roller 130. In addition, the use of the air shaft is eliminated, simplifying the equipment and providing users with a better user experience.

All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
