Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to an automatic label removal mechanism. Background Art

[0002] In labeling machine designs, a rejection process is typically placed after the product labeling and pressing process, removing all defective products simultaneously. This includes both defective labels and defective labeling. Defective products are generally categorized into two types: one is a defective label, identified through photoelectric or CCD omission detection. This includes missing or misprinted characters, missing or stained label text, and so on. The other is a defective label, identified through photoelectric or CCD omission detection. This includes missing labels, wrinkles, or bubbles. The typical process involves applying both qualified and defective labels to the product, then locating the product for rejection.

[0003] The existing technology has the following deficiencies: the automatic label removal mechanism of the existing labeling machine cannot conveniently detect whether the label is qualified during operation, and thus cannot quickly remove unqualified labels, so that unqualified labels can easily be attached to the surface of qualified products. When an unqualified label is detected, the label needs to be removed again, which affects the efficiency of product labeling. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic label removal mechanism. When a qualified label is detected, the cylinder extends to adjust the position of the second paper feeding roller. The qualified label is sequentially conveyed to the rear section through the first paper feeding roller, the second paper feeding roller, and the third paper feeding roller. When an unqualified label is detected, the cylinder contracts to extend the label peeling plate forward so that the unqualified label can be peeled off, thereby solving the above-mentioned shortcomings in the technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic label removal mechanism, comprising a lower fixed plate, a second adjusting block is fixedly installed on one end of the top of the lower fixed plate, a third paper feeding roller is rotatably installed on one side of the second adjusting block, a first fixed shaft is rotatably installed on one end of the lower fixed plate away from the second adjusting block, a first swing arm is fixedly sleeved on the outer side of the first fixed shaft, a cylinder is provided at one end of the first swing arm, the second paper feeding roller is rotatably installed on the bottom of one side of the first swing arm, a label peeling plate is fixedly installed on the other side of the first swing arm, a tension spring is provided on the end of the first swing arm close to the label peeling plate, a second swing arm is fixedly installed on the end of the tension spring away from the first swing arm, a fourth paper feeding roller is rotatably installed on the top of one side of the second swing arm, and a guide axis is rotatably installed on the side of the lower fixed plate close to the tension spring.

[0006] Preferably, a first adjusting block is fixedly mounted on one end of the lower fixing plate close to the second adjusting block, and a center line of the first adjusting block is perpendicular to a center line of the second adjusting block.

[0007] Preferably, a first paper feeding roller is rotatably mounted on one side of the top of the lower fixed plate, a label rolling wheel is rotatably mounted on the other side of the top of the lower fixed plate, and a second sprocket is fixedly sleeved on the top of the label rolling wheel.

[0008] Preferably, a second fixed shaft is fixedly mounted on a top side of the lower fixed plate away from the first paper feeding roller, and an outer wall of the second fixed shaft is rotatably connected to the second swing arm.

[0009] Preferably, a fisheye joint is fixedly installed on the end of the first swing arm away from the second adjustment block, the fisheye joint is fixedly connected to the output end of the cylinder, and a fixing seat for fixing the cylinder is fixedly installed on the outer side of the end of the cylinder away from the fisheye joint.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. By detecting whether the label is qualified or not, when it is detected that the label is qualified, the cylinder extends to adjust the position of the second paper feeding roller, so that the label can pass through the first paper feeding roller, the second paper feeding roller and the third paper feeding roller in sequence for normal transportation. When it is detected that the label is unqualified, the cylinder contracts, and the transmission effect of the first swing arm causes the label peeling plate to move toward one end, so that the label can pass through the first paper feeding roller and the third paper feeding roller and come into contact with the guide shaft, so that the label peeling plate can peel off the unqualified label and stick it to the outside of the fourth paper feeding roller, and then pass through the label rolling wheel to remove the label on its surface, so that the device can conveniently remove unqualified labels, which can improve the efficiency of product labeling;

[0015] 2. The motor is used to rotate the label roller, which in turn drives the fourth paper feeding roller to rotate, so that the peeled unqualified labels can be easily rolled up and removed, thereby ensuring the continuous operation of the device and improving the efficiency of label removal.

A second swing arm 21 is fixedly mounted on the end away from the first swing arm 12. A fourth paper feed roller 20 is rotatably mounted on the top of one side of the second swing arm 21. A guide shaft 18 is rotatably mounted on the side of the lower fixed plate 6 near the tension spring 23. The position of the second paper feed roller 11 and the label peeling plate 19 can be adjusted by extending and contracting the cylinder 14, thereby conveniently peeling off unqualified labels. The tension spring 23 is mounted on one end of the second swing arm 21 and is disposed at the bottom of the fourth paper feed roller 20. It is used to ensure that the label rolling wheel 17 and the fourth paper feed roller 20 are always in close contact, allowing the label rolling wheel 17 to rotate with the fourth paper feed roller 20.

[0025] In order to keep the second paper feeding roller 11 stable during the adjustment process, Figure 2-4 As shown, the first adjustment block 7 is fixedly installed at one end of the lower fixed plate 6 close to the second adjustment block 8, and the center line of the first adjustment block 7 is perpendicular to the center line of the second adjustment block 8. The first adjustment block 7 and the second adjustment block 8 can limit the position of the second paper feeding roller 11 so that it can stably guide and transport the labels.

[0026] In order to make the label roller 17 able to easily remove the unqualified labels on the outer side of the fourth paper feeding roller 20, Figure 2-4 As shown, a first paper feeding roller 10 is rotatably mounted on one side of the top of the lower fixed plate 6, a label rolling wheel 17 is rotatably mounted on the other side of the top of the lower fixed plate 6, a second sprocket 5 is fixedly sleeved on the top of the label rolling wheel 17, a second fixed shaft 22 is fixedly mounted on one side of the top of the lower fixed plate 6 away from the first paper feeding roller 10, an outer wall of the second fixed shaft 22 is rotatably connected to the second swing arm 21, and the rotation of the second sprocket 5 causes the label rolling wheel 17 to rotate, and the label rolling wheel 17 can remove unqualified labels pasted on the outside of the fourth paper feeding roller 20, so that the fourth paper feeding roller 20 can be continuously used for pasting unqualified labels.

[0027] In order to make the cylinder 14 work stably, Figure 2-4As shown, a fisheye joint 13 is fixedly installed at one end of the first swing arm 12 away from the second adjustment block 8, and the fisheye joint 13 is fixedly connected to the output end of the cylinder 14. A fixing seat 15 for fixing the cylinder 14 is fixedly installed on the outer side of one end of the cylinder 14 away from the fisheye joint 13. The fixing seat 15 can install and fix the cylinder 14. The output end of the cylinder 14 is connected to the first swing arm 12 through the fisheye joint 13, and then the operation of the cylinder 14 can drive the first swing arm 12 to move.

[0028] In order to provide power for the rotation of the roller wheel 17, Figure 1 As shown, an upper fixed plate 1 is provided on the top of the lower fixed plate 6, and a reducer 3 is fixedly installed on the bottom of one end of the upper fixed plate 1. The input end of the reducer 3 is provided with a motor 2, and the output end of the reducer 3 passes through the upper fixed plate 1 and is fixedly installed with a first sprocket 4. When the motor 2 works, the first sprocket 4 is rotated by the deceleration of the reducer 3, and then the second sprocket 5 is rotated through the transmission chain, which can drive the roller wheel 17 to rotate.

[0029] In order to facilitate the delivery of labels, Figure 2-4 As shown, the diameter of the first paper feed roller 10 is the same as the diameter of the second paper feed roller 11, the diameter of the second paper feed roller 11 is the same as the diameter of the third paper feed roller 9 and the fourth paper feed roller 20, the guide axis 18 is set in the gap between the label roller 17 and the tension spring 23, the height of the label stripping plate 19 is the same as the height of the fourth paper feed roller 20, the first paper feed roller 10, the second paper feed roller 11, and the third paper feed roller 9 can stably transport labels, and the height of the label stripping plate 19 is the same as the height of the fourth paper feed roller 20, so that the label stripping plate 19 can stably remove unqualified labels.

[0030] When the labeling machine is in use, a label detection mechanism 25 and a qualified label peeling mechanism are installed on the outside of the labeling main head mechanism 24, and an automatic label rejection mechanism is arranged between the label detection mechanism 25 and the qualified label peeling mechanism 26. After being detected by the label detection mechanism 25, the label enters the device and can be conveyed through the first paper feeding roller 10. When the label is qualified, the cylinder 14 extends to push the first swing arm 12 to move, thereby causing the second paper feeding roller 11 to move toward the second adjustment block 8, and then under the limitation and guidance of the second paper feeding roller 11 and the second adjustment block 8, the qualified label can be conveyed, and then the label can be further conveyed through the third paper feeding roller 9, so that the label passes from the side of the guide axis 18 but does not come into contact with it;

[0031] When the label is detected as unqualified, the cylinder 14 contracts and drives the first swing arm 12 to move toward the cylinder 14, and then drives the label peeling plate 19 to move toward the guide axis 18. The label can be transported through the first paper feeding roller 10 and the third paper feeding roller 9. The label peeling plate 19 can peel off the unqualified label through the guidance of the guide axis 18, so that the unqualified label can be pasted to the outside of the fourth paper feeding roller 20. The motor 2 works through the deceleration effect of the reducer 3 to rotate the first sprocket 4, and through the transmission effect of the transmission chain, the second sprocket 5 is rotated, which can drive the label rolling wheel 17 to rotate. The friction between the fourth paper feed roller 20 causes the fourth paper feed roller 20 to rotate accordingly, so that unqualified labels can be continuously pasted on its outer wall. At the same time, the setting of the tension spring 23 allows the fourth paper feed roller 20 to always fit with the label roller 17. When the diameter of the unqualified label pasted on the outer side of the fourth paper feed roller 20 reaches a larger diameter, it can be removed, so that the fourth paper feed roller 20 can continue to be used for subsequent unqualified label pasting work, thereby allowing the device to conveniently remove unqualified labels, thereby improving the efficiency of product labeling. This embodiment specifically solves the problem in the prior art that it is inconvenient to remove unqualified labels, which affects the efficiency of product labeling.

[0032] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
