Description

Technical Field

[0001] The present invention relates to the technical field of rewinding machines, and more specifically, to an automatic labeling rewinding machine. Background Art

[0002] During the film production process, the film needs to be rewound and labeled during the rewinding process to facilitate the tearing off of the film layer by layer. The film is then cut into individual finished products for packaging and sale in the market. However, existing film rewinding machines are all semi-manually operated, which has problems such as low efficiency and inconsistent rewinding results.

[0003] The invention patent with announcement number CN106006139B discloses an automatic rewinding machine, including a frame, a control system, a rewinding and cutting mechanism for rewinding and cutting raw materials, a winding mechanism for rewinding the rewinded and cut raw materials, a labeling mechanism for sealing and labeling the products rewound by the winding mechanism, a feeding mechanism for providing raw materials to the rewinding and cutting mechanism, a rotating clamping mechanism for transferring paper tubes to the rewinding and cutting mechanism, a paper tube unloading device for providing paper tubes to the rotating clamping mechanism, and a glue dripping device for gluing the paper tubes. The rewinding and cutting mechanism, the winding mechanism, the labeling mechanism, the feeding mechanism, the rotating clamping mechanism, the paper tube unloading device, and the glue dripping device are all arranged on the frame, and the rewinding and cutting mechanism, the winding mechanism, the labeling mechanism, the feeding mechanism, the rotating clamping mechanism, and the glue dripping device are all connected to the control system.

[0004] However, the labeling mechanism of the automatic rewinding machine of the above technical solution is only used for product sealing and labeling. In the actual film processing process, labels are usually affixed between each film to facilitate the tearing of each layer of film. For this operation, the above patent is not applicable. Summary of the Invention

[0005] In view of this, in order to solve the above problems, the present invention proposes an automatic labeling rewinding machine, including a rewinding roller 1 and a labeling machine 2, characterized in that: a support frame 3 is provided near the body of the rewinding roller 1, the support frame 3 is an L-shaped structure, the horizontal support of the support frame 3 is located at the bottom of the rewinding roller 1, for strengthening the supporting force of the rewinding roller 1, the vertical support of the support frame 3 is provided with a Z-axis transport mechanism 5 and a Y-axis transport mechanism 4, the Z-axis transport mechanism 5 is detachably connected to the Y-axis transport mechanism 4, and the Z-axis transport mechanism 5 is provided with a labeling machine 2, and the labeling machine 2 is arranged on the side facing the rewinding operation of the rewinding roller 1, and the labeling machine 2 is provided with a label unwinding roll 22, a bottom material recovery roll 23 and a coil power shaft 28, the coil power shaft 28 drives the label unwinding roll 22 to perform the labeling operation during the rewinding operation of the rewinding roller 1, and then recovers the bottom material that has been labeled through the bottom material recovery roll 23, thereby completing the automatic labeling operation.

[0006] Furthermore, the Y-axis transport mechanism 4 is a gate-shaped structure, which is arranged at the top and both sides of the support frame 3. A crawler 41 is provided on each side of the Y-axis transport mechanism 4, and a first guide rail 31 is provided on both sides of the support frame 3. Each of the first guide rails 31 and the corresponding crawler 41 are arranged parallel to each other, and each crawler 41 is connected to a right-angle tripod 6 and a crawler 41 driving mechanism. The crawler 41 driving mechanism is located at the top of the support frame 3, and the two right-angle sides of the right-angle tripod 6 are respectively connected to the Y-axis transport mechanism 4 and the Z-axis transport mechanism 5. A right-angle side of the right-angle tripod 6 is provided with a mounting block 61 and a first slider group 62. One side of the mounting block 61 is clamped with the crawler 41, and the other side is connected to the right-angle tripod 6. The first slider group 62 is slidably connected to the first guide rail 31 on the support frame 3. When the crawler 41 moves longitudinally, it drives the right-angle tripod to move longitudinally.

[0007] Furthermore, the crawler 41 driving mechanism includes a screw rod 42 and a first motor 43. The driving wheel of the first motor 43 is engaged with the follower wheel fixedly sleeved on the screw rod 42. The rotating gears provided at both ends of the screw rod 42 are engaged with the teeth of the inner wall of the crawler 41. During operation, the first motor 43 drives the driving wheel to rotate, thereby driving the screw rod 42 to rotate. During the rotation of the screw rod 42, the rotating gears at both ends are driven to rotate, thereby driving the crawler 41 to cyclically move, thereby realizing the longitudinal adjustment of the right-angle tripod 6.

[0008] Furthermore, the Z-axis transport mechanism 5 is located on one side of the Y-axis transport mechanism 4, and the Z-axis transport mechanism 5 includes a cylinder 51. Each of the right-angle tripods is provided with a second guide rail 63 on the right-angle side perpendicular to the first guide rail 31. The second guide rail 63 is matched with a second slider. The upper part of the second slider is connected to the mounting bracket 53 of the labeling machine 2. The driving shaft of the cylinder 51 is connected to the second slider close to it. The cylinder 51 is used to push the second slider group 52 to move back and forth on the right-angle tripod 6, thereby realizing the forward and backward movement adjustment of the Z-axis transport mechanism 5, and further realizing the forward and backward movement adjustment of the labeling machine 2.

[0009] Furthermore, an X-axis transport mechanism 21 is also provided on the mounting bracket 53, and the X-axis transport mechanism 21 includes a second motor 211, a guide rod 212 and a screw rod 213. The surface of the guide rod 212 is smooth and is used to strengthen the supporting force. The second motor 211 is connected to the screw rod 213 and controls the rotation of the screw rod 213. The surface of the screw rod 213 is threaded. The labeling machine 2 is sleeved on the guide rod 212 and the screw rod 213. When the second motor 211 is running, it drives the guide rod 212 and the screw rod 213 to rotate. The labeling machine 2 moves left and right on the screw rod 213 and the guide rod 212 through the rotation of the screw rod 213, thereby realizing the lateral adjustment of the labeling machine 2.

[0010] Furthermore, the label material roll on the labeling machine 2 is divided into labels and base material, and the labels and the base material are in an adsorption state, and there is no adhesive force between the labels and the base material.

[0011] Furthermore, the labeling machine 2 is also provided with a buffer pendulum 24, a guide roller 25, a pressure plate 26 and a pressure wheel 27. The label material roll that has not been labeled is placed on the label unloading roll 22. The label material roll is first transported to the input end of the buffer pendulum 24 through the output end of the label unloading roll 22, and then transported to the input end of the guide roller 25 through the output end of the buffer pendulum 24. The output end of the guide roller 25 transports the unlabeled label material roll to the pressure plate 26. The pressure wheel 27 presses the label on the pressure plate 26 onto the rewinding roller 1. The bottom material recovery roll 23 recovers the bottom material roll that has been labeled on the pressure plate 26.

[0012] Furthermore, the pressure plate 26 is tilted toward the side of the rewinding roller 1, and the upper end of the pressure plate 26 abuts against the body of the rewinding roller 1. The pressure wheel 27 is arranged above the pressure plate 26 and abuts against the rewinding roller 1. Since there is no adhesion between the label and the base material, when the label is transported to the upper end of the pressure plate 26, the front end of the label will be separated from the base material and affixed to the rewinding roller 1 through the pressure of the abutment of the pressure plate 26. A spring is provided on the pressure wheel 27. When the front end of the label is affixed to the rewinding roller 1, the pressure wheel 27 will press the front end of the label. As the rewinding roller 1 runs, the remaining label will detach from the base material, and the pressure wheel 27 will completely press the remaining label onto the rewinding roller 1.

[0013] Furthermore, the unlabeled label roll on the pressure plate 26 is transported from the lower end of the pressure plate 26 to the upper end of the pressure plate 26, and is opposite to the rewinding direction of the rewinding roller 1. A sensor is provided between the upper end of the pressure plate 26 and the pressure wheel 27. The sensor is provided close to the rewinding roller 1 to sense whether the label has come out.

[0014] Furthermore, the buffer pendulum 24 is arranged close to the label unloading roll 22 to relieve the tension of the unlabeled label roll during transportation, and prevent the bottom material of the roll from being stretched straight and causing the label to fall off. The label unloading roll 22 and the bottom material recovery roll 23 are both provided with a roll quick-carrying handle 7 for manually adjusting the starting position on the label unloading roll 22 and the bottom material recovery roll 23 before labeling.

[0025] In some embodiments, the Y-axis transport mechanism 4 is a gate-shaped structure, which is arranged at the top and both sides of the support frame 3. A crawler 41 is provided on each side of the Y-axis transport mechanism 4, and a first guide rail 31 is provided on both sides of the support frame 3. Each of the first guide rails 31 is arranged parallel to the corresponding crawler 41. Each crawler 41 is connected to a right-angle tripod 6 and a crawler 41 driving mechanism. The crawler 41 driving mechanism is located at the top of the support frame 3. The two right-angle sides of the right-angle tripod 6 are respectively connected to the Y-axis transport mechanism 4 and the Z-axis transport mechanism 5. A right-angle side of the right-angle tripod 6 is provided with a mounting block 61 and a first slider group 62. One side of the mounting block 61 is clamped with the crawler 41, and the other side is connected to the right-angle tripod 6. The first slider group 62 is slidably connected to the first guide rail 31 on the support frame 3. When the crawler 41 moves longitudinally, it drives the right-angle tripod to move longitudinally.

[0026] The crawler belt 41 driving mechanism includes a screw rod 42 and a first motor 43. The driving wheel of the first motor 43 is engaged with the driven wheel fixedly sleeved on the screw rod 42. The rotating gears provided at both ends of the screw rod 42 are engaged with the teeth of the inner wall of the crawler belt 41. During operation, the first motor 43 drives the driving wheel to rotate, thereby driving the screw rod 42 to rotate. During the rotation of the screw rod 42, the rotating gears at both ends are driven to rotate, thereby driving the crawler belt 41 to cyclically move, thereby realizing the longitudinal adjustment of the right-angle tripod 6.

[0027] In some embodiments, the Z-axis transport mechanism 5 is located on one side of the Y-axis transport mechanism 4, and the Z-axis transport mechanism 5 includes a cylinder 51. Each of the right-angle tripods is provided with a second guide rail 63 on the right-angle side perpendicular to the first guide rail 31. The second guide rail 63 is matched with a second slider. The upper part of the second slider is connected to the mounting bracket 53 of the labeling machine 2. The driving shaft of the cylinder 51 is connected to the second slider close to it. The cylinder 51 is used to push the second slider group 52 to move back and forth on the right-angle tripod 6, thereby realizing the forward and backward movement adjustment of the Z-axis transport mechanism 5, and further realizing the forward and backward movement adjustment of the labeling machine 2.

[0028] In some embodiments, an X-axis transport mechanism 21 is further provided on the mounting bracket 53, and the X-axis transport mechanism 21 includes a second motor 211, a guide rod 212 and a screw rod 213. The surface of the guide rod 212 is smooth and is used to strengthen the supporting force. The second motor 211 is connected to the screw rod 213 and controls the rotation of the screw rod 213. The surface of the screw rod 213 is threaded. The labeling machine 2 is sleeved on the guide rod 212 and the screw rod 213. When the second motor 211 is running, it drives the guide rod 212 and the screw rod 213 to rotate. The labeling machine 2 moves left and right on the screw rod 213 and the guide rod 212 through the rotation of the screw rod 213, thereby realizing the lateral adjustment of the labeling machine 2.

[0029] The label material roll on the labeling machine 2 is divided into labels and base material. The labels and the base material are in an adsorption state, and there is no adhesive force between the labels and the base material.

[0030] In some embodiments, the labeling machine 2 is further provided with a buffer pendulum 24, a guide roller 25, a pressure plate 26 and a pressure wheel 27. An unlabeled label roll is placed on the label unwinding roll 22. The label roll is first transported to the input end of the buffer pendulum 24 through the output end of the label unwinding roll 22, and then transported to the input end of the guide roller 25 through the output end of the buffer pendulum 24. The output end of the guide roller 25 transports the unlabeled label roll to the pressure plate 26. The pressure wheel 27 presses the label on the pressure plate 26 onto the rewinding roller 1. The bottom material recovery roll 23 recovers the bottom material roll that has been labeled on the pressure plate 26.

[0031] The pressure plate 26 is tilted toward the side of the rewinding roller 1 where the label is rewound. The upper end of the pressure plate 26 abuts against the body of the rewinding roller 1. The pressure wheel 27 is arranged above the pressure plate 26 and abuts against the rewinding roller 1. Since there is no adhesion between the label and the base material, the front end of the label will be separated from the base material when the label is transported to the upper end of the pressure plate 26 and will be attached to the rewinding roller 1 through the pressure of the abutment of the pressure plate 26. A spring is provided on the pressure wheel 27. When the front end of the label is attached to the rewinding roller 1, the pressure wheel 27 will press the front end of the label. As the rewinding roller 1 runs, the remaining labels will separate from the base material, and the pressure wheel 27 will completely press the remaining labels onto the rewinding roller 1.

[0032] The unlabeled label roll on the pressure plate 26 is transported from the lower end of the pressure plate 26 to the upper end of the pressure plate 26, and is opposite to the rewinding direction of the rewinding roller 1. A sensor is provided between the upper end of the pressure plate 26 and the pressure wheel 27. The sensor is provided close to the rewinding roller 1 to sense whether the label has come out.

[0033] The buffer pendulum 24 is arranged near the label unloading roll 22 to relieve the tension of the unlabeled label roll during transportation, so as to prevent the bottom material of the roll from being stretched straight and causing the label to fall off. The label unloading roll 22 and the bottom material recovery roll 23 are both provided with a roll quick carrying handle 7 for manually adjusting the starting position of the label unloading roll 22 and the bottom material recovery roll 23 before labeling.
