DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 4The paper roll feeding and unwinding device shown in the figure includes a machine base 1, a feeding mechanism 2 and a roller 3. The two machine bases 1 are arranged and installed in parallel. The machine base 1 is fixedly installed on the workshop floor. A gap space is formed between the two machine bases 1. The gap space can accommodate the entry of the paper roll. The utility model is equipped with a special roller 3 for the paper roll. The paper roll is mounted on the roller 3. The paper roll is transported to the position between the two machine bases 1 by a forklift or other equipment, and then automatically loaded by the feeding mechanism 2. The feeding mechanism 2 includes a chain transmission group 21 and a chain power component 23. There are two chain transmission groups 21. The two chain transmission groups 21 are respectively installed on the two machine bases 1. The two chain transmission groups 21 are symmetrically installed. A hook 22 is installed on each chain transmission group 21. The hook 22 is used to carry the roller 3 carrying the paper roll. The chain power component 23 is connected to the two chain transmission groups 21 for transmission. The two hooks 22 can be driven to move synchronously by the chain power component 23. The two ends of the roller 3 are respectively The paper roll is unwound during rotation and the paper belt is unwound after it is unloaded, and the paper roll is unwound after it is unloaded.

[0022] like Figure 2As shown, the chain transmission group 21 includes a chain driving gear 211 and a plurality of chain transmission gears 212. The chain driving gear 211 and the chain transmission gear 212 are both rotatably mounted on the side wall of the machine base 1. The chain driving gear 211 and the plurality of chain transmission gears 212 are transmission-mounted with a load chain 213. When the chain driving gear 211 and the plurality of chain transmission gears 212 rotate, the load chain 213 can flow and move. The hook 22 is mounted on the load chain 213. The two hooks 22 are symmetrically arranged to ensure that the roller shaft 3 can be mounted horizontally. When the two hooks 22 move synchronously, the roller shaft 3 can be mounted horizontally. The lifting and lowering movement of the shaft 3 and the roller 3 means that the paper roll can be lifted and lowered. When the present invention is used, the two hooks 22 first move to the lowest point, and then the paper roll is placed between the two machine bases 1. As the two hooks 22 are lifted, the hooks 22 can move toward the roller 3 position of the paper roll. The hooks 22 are installed with the open end facing upward to ensure that the roller 3 falls smoothly into the hooks 22. As the hooks 22 continue to rise, the heavy paper roll will be completely lifted off the ground, realizing the automatic loading function. The loading end point is at the top plane of the machine base 1. When the hooks 22 move to the top plane position of the machine base 1, the roller 3 is detached from the hooks 22.

[0023] like Figure 1 and Figure 2 As shown, the chain power assembly 23 includes a power spindle 231 and a first motor 232. The driving gears 211 of the two chain transmission groups 21 are fixedly connected to the power spindle 231. The power spindle 231 is rotatably installed. The first motor 232 is installed on one of the machine bases 1. The output end of the first motor 232 is connected to the power spindle 231. After the first motor 232 is started, it can drive the power spindle 231 to rotate, and then realize the synchronous transmission of the two chain transmission groups 21 through the two driving gears 211, so that the two hooks 22 can move synchronously.

[0024] like Figure 1 and Figure 2 As shown, the machine base 1 is provided with a loading slope 11, and a guide groove 111 is opened on the loading slope 11. During the paper roll unwinding operation, the paper roll can only rotate, and other position relationships must be relatively fixed. Therefore, a locking frame 5 is installed on the top of the machine base 1. The locking frame 5 can position the roller 3 so that the roller 3 does not move, but does not affect the rotation of the roller 3. The roller 3 can rotate, that is, the paper roll can rotate. The guide groove 111 on the machine base 1 extends into the locking frame 5. The guide groove 111 plays a role in guiding the direction of the roller 3 during the lifting process, so that the roller 3 can smoothly and accurately enter the locking frame 5. Figure 3As shown, both ends of the roller shaft 3 are respectively connected to an axis head 31, and a supporting wheel 32 is rotatably installed on each axis head 31. The thickness of the supporting wheel 32 matches the guide groove 111. During the lifting and upward movement of the roller shaft 3, the supporting wheel 32 rolls upward along the length direction of the guide groove 111. The guide groove 111 can guide the roller shaft 3 to move upward in the correct direction through the supporting wheel 32. When the roller shaft 3 is lifted to the top plane of the machine base 1, the supporting wheel 32 can smoothly roll into the locking frame 5 and be locked and fixed. The supporting wheel 32 is fixed, which means that the orientation of the roller shaft 3 and the paper roll is determined, preventing problems such as paper feed deviation during the unwinding operation. Since the supporting wheel 32 and the axis head 31 are rotatably installed, the fixing of the supporting wheel 32 does not affect the rotation of the roller shaft 3, and the paper roll can meet the normal rotation and unwinding operation.

[0025] like Figure 2 and Figure 4 As shown, a locking frame 5 is installed on the top of the two machine bases 1. The locking frame 5 is L-shaped. The locking frame 5 is open to face the forward direction of the supporting wheel 32, so that the supporting wheel 32 rolls into the locking frame 5. A locking screw 51 is threadedly installed on the locking frame 5. The locking screw 51 is installed upright, and an assisting handle head 52 is connected to the top of the locking screw 51. The assisting handle head 52 can assist in twisting the locking screw 51. After the locking screw 51 is twisted to the rising limit, the locking frame 5 is fully opened and the supporting wheel 32 can roll in smoothly. After the locking screw 51 is twisted downward to the descending limit, the supporting wheel 32 will be clamped and locked in the locking frame 5. At this time, the supporting wheel 32 cannot move, but it does not affect the normal rotation of the roller shaft 3 connected to it.

[0026] like Figure 1 and Figure 4 As shown, an unwinding transmission gear 33 is fixedly mounted on one of the shaft heads 31 of the roller shaft 3, and the unwinding power mechanism 4 includes a motor base 41 and a second motor 42. The motor base 41 is fixed to the side wall of the machine base 1, and the second motor 42 is fixedly mounted on the motor base 41. The output end of the second motor 42 is connected to the unwinding driving gear 43. After the roller shaft 3 is locked on the locking frame 5, the unwinding transmission gear 33 is just engaged with the unwinding driving gear 43. As the second motor 42 is started, the unwinding driving gear 43 can drive the unwinding transmission gear 33 and the roller shaft 3 to rotate, and finally form a rotating unwinding effect of the paper roll. In the present utility model, the guide groove 111 on the machine base 1 is designed so that the movement direction of the roller shaft 3 is correctly guided, so as to ensure that after the roller shaft 3 falls behind, the unwinding transmission gear 33 is just engaged with the unwinding driving gear 43.
