Description

Technical Field

[0001] This utility model relates to the field of labeling device technology, and in particular to a labeling device for processing plastic cups. Background Technology

[0002] Labeling devices are automated mechanical equipment that can accurately affix labels to plastic cups. In the plastic cup processing, labeling devices can greatly improve production efficiency, reduce manual operation, and lower production costs, making them a commonly used piece of machinery in the plastic bottle production process.

[0003] The labeling device mainly involves placing multiple plastic cups on a conveyor belt for transport, allowing the cups to move at a uniform speed. A labeling cylinder is installed on one side of the conveyor belt, and a rotating shaft with a label tape on it is located inside the cylinder. When the plastic cups pass through the labeling cylinder driven by the conveyor belt, the rotating shaft causes the label tape to rotate, resulting in a label with adhesive on one side being applied to the plastic cup. However, as the plastic cups move on the conveyor belt, they are prone to shifting, which may cause the label to be applied crookedly, thus reducing the yield rate of the plastic cups. Summary of the Invention

[0004] This invention provides a labeling device for plastic cup processing to address the problem that plastic cups are prone to displacement when moving on a conveyor belt, which may lead to misaligned labels and reduced yield of plastic cups.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a labeling device for processing plastic cups, comprising a base, a housing fixedly connected to one side of the top of the base, a conveyor belt arranged inside the housing, rollers symmetrically arranged inside the conveyor belt, the two ends of the rollers being rotatably connected to the two sides of the housing respectively, a servo motor arranged on one side of the housing, the output end of the servo motor being fixedly connected to one end of one of the rollers, a rotating rod rotatably connected to the other side of the top of the base, a labeling cylinder arranged on one side of the housing, the rotating rod being rotatably connected to the inner wall of the labeling cylinder, and a limit device arranged at the top of the conveyor belt. Four extension plates are provided, with one side of each extension plate symmetrically fixed to both sides of the housing. A slider is slidably connected to the inner wall of each extension plate. A first threaded rod is fixedly connected to one side of two sliders. Two circular hole plates are slidably connected to the outer surface of the first threaded rod. A limiting plate is fixedly connected to one side of the two circular hole plates. A screw hole block is fixedly connected to the other side of each slider. A second threaded rod is threadedly connected to the inner wall of the screw hole block. An extension block is provided at one end of the second threaded rod. One side of the extension block is fixedly connected to one side of the housing. Rollers are provided at the four corners of the bottom of the base. A positioning device is provided at the bottom of the outer surface of the base.

[0006] The effect achieved by the above components is as follows: by setting two limiting plates, pushing the two limiting plates causes the circular hole plate to slide on the outer surface of the first threaded rod until one side of the two limiting plates is about to abut against the outer surface of the plastic cup on the conveyor belt. Then, rotating the four second threaded rods causes the slider connected to the extension block to slide on the inner wall of the extension plate. The slider will drive the first threaded rod and the limiting plates to move vertically until the limiting plates no longer obstruct the position of the plastic cup for labeling. Thus, the limiting plates can block the plastic cup, which helps to prevent the plastic cup from shifting on the conveyor belt and causing the label to be affixed crookedly, thereby improving the yield of plastic cups.

[0007] Preferably, one end of the second threaded rod is fixedly connected to a bearing, and the outer surface of the bearing is fixedly connected to the inner wall of the extension block.

[0008] The effect achieved by the above components is that by setting bearings, the friction between the threaded rod and the extension block can be reduced when rotating the second threaded rod, making it easier to rotate the second threaded rod.

[0009] Preferably, an operating block is fixedly connected to the other end of the second threaded rod, and the outer surface of the operating block is provided with protrusions.

[0010] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the second threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0011] Preferably, nuts are provided on both sides of the circular hole plate, and the outer surface of the first threaded rod is threadedly connected to the inner walls of the two nuts.

[0012] The effect achieved by the above components is as follows: by setting two nuts and rotating the nuts so that one side of the nut abuts against one side of the circular hole plate, the two nuts can fix the circular hole plate and the first threaded rod, thereby fixing the limiting plate and preventing the limiting plate from shifting after adjustment.

[0013] Preferably, a rubber ring is fixedly connected to the side of the nut near the circular hole plate, and the outer surface of the first threaded rod is disposed inside the rubber ring.

[0014] The effect achieved by the above components is that by setting the rubber ring, the friction between the nut and the round hole plate can be increased, which helps to prevent the nut from loosening.

[0015] Preferably, the positioning device includes an auxiliary plate, which is sleeved on the bottom of the outer surface of the base. Rectangular rods are symmetrically fixedly connected to both sides of the auxiliary plate, and auxiliary blocks are symmetrically fixedly connected to both sides of the base. The outer surface of the rectangular rods is slidably connected to the inner wall of the auxiliary block, and bolts are threaded into the inner wall of the auxiliary block.

[0016] The effect achieved by the above components is as follows: by setting up an auxiliary plate, the auxiliary plate is pushed to move vertically until the bottom of the auxiliary plate abuts against the ground. Then, the bolt is rotated so that one end of the bolt abuts against one side of the rectangular rod, which can fix the auxiliary plate. The auxiliary plate can increase the friction between the base and the ground, which helps to prevent the labeling device from easily shifting or tipping over.

[0017] Preferably, an auxiliary groove is provided on one side of the rectangular rod, and a rubber strip is fixedly connected to the inner wall of the auxiliary groove.

[0018] The effect achieved by the above components is that by setting the rubber strip, the friction between one end of the bolt and the rectangular rod can be increased, making the bolt more securely fixed to the auxiliary plate.

[0019] Preferably, a rectangular block is fixedly connected to one end of the rectangular rod.

[0020] The effect achieved by the above components is that by setting up a rectangular block, one end of the rectangular rod can be blocked, which helps to prevent the rectangular rod from detaching from the inner wall of the auxiliary block due to misoperation.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, two limiting plates are set up. By pushing the two limiting plates, one side of the two limiting plates will be about to abut against the outer surface of the plastic cup on the conveyor belt. Then, four second threaded rods drive the limiting plates to move vertically until the limiting plates no longer obstruct the position of the plastic cup where the label is affixed. The limiting plates can then block the plastic cup, which helps to prevent the plastic cup from shifting on the conveyor belt and causing the label to be affixed crookedly, thereby improving the yield of the plastic cup.

[0028] Example 1, referring to Figures 1-3As shown, this embodiment discloses a labeling device for processing plastic cups, including a base 1, a housing 4 fixedly connected to one side of the top of the base 1, a conveyor belt 5 disposed inside the housing 4, rollers 6 symmetrically disposed inside the conveyor belt 5, the two ends of the rollers 6 being rotatably connected to the two sides of the housing 4 respectively, a servo motor 7 disposed on one side of the housing 4, the output end of the servo motor 7 being fixedly connected to one end of one of the rollers 6, a rotating rod 8 rotatably connected to the other side of the top of the base 1, a labeling cylinder 9 disposed on one side of the housing 4, the rotating rod 8 being rotatably connected to the inner wall of the labeling cylinder 9, and a labeling cylinder 9 disposed on the top of the conveyor belt 5. The device includes a limiting device 2 with four extension plates 21. One side of each extension plate 21 is symmetrically fixed to both sides of the housing 4. A slider 22 is slidably connected to the inner wall of each extension plate 21. A first threaded rod 23 is fixedly connected to one side of each slider 22. Two circular hole plates 24 are slidably connected to the outer surface of the first threaded rod 23. A limiting plate 25 is fixedly connected to one side of each circular hole plate 24. A screw hole block 26 is fixedly connected to the other side of each slider 22. A second threaded rod 27 is threadedly connected to the inner wall of the screw hole block 26. An extension block 28 is provided at one end of the second threaded rod 27. One side of the extension block 28 is fixedly connected to one side of the housing 4. Rollers 10 are provided at the four corners of the bottom of the base 1. A positioning device 3 is provided at the bottom of the outer surface of the base 1. By setting two limiting plates 25, pushing the two limiting plates 25 will cause the circular hole plate 24 to slide on the outer surface of the first threaded rod 23 until one side of the two limiting plates 25 is about to abut against the outer surface of the plastic cup on the conveyor belt 5. Then, the four second threaded rods 27 are rotated to drive the slider 22 connected to the extension block 28 to slide on the inner wall of the extension plate 21. The slider 22 will drive the first threaded rod 23 and the limiting plate 28 to slide. 5. Move vertically until the limiting plate 25 no longer obstructs the labeling position on the plastic cup. The limiting plate 25 can block the plastic cup, which helps to prevent the plastic cup from shifting on the conveyor belt 5 and causing the label to be applied crookedly, thereby improving the yield of the plastic cup. The rotating shaft is connected to the motor output end inside the base 1, and the outer surface of the rotating shaft inside the label tube is wrapped with label tape. When the plastic cup passes through the labeling tube 9 under the drive of the conveyor belt 5, the output end of the motor will drive the rotating shaft to rotate, and the rotating shaft will drive the label tape to rotate, so that the label with adhesive on one side is applied to the plastic cup.

[0029] Reference Figure 2 and Figure 3As shown, a bearing 29 is fixedly connected to one end of the second threaded rod 27. The outer surface of the bearing 29 is fixedly connected to the inner wall of the extension block 28. By setting the bearing 29, the friction between the threaded rod and the extension block 28 can be reduced when rotating the second threaded rod 27, making it easier to rotate the second threaded rod 27. An operating block 210 is fixedly connected to the other end of the second threaded rod 27. The outer surface of the operating block 210 is provided with protrusions. By setting the operating block 210, rotating the operating block 210 can drive the second threaded rod 27 to rotate. At the same time, the protrusions on the outer surface of the operating block 210 can effectively increase the friction on the outer surface of the operating block 210, which has an anti-slip effect when rotating the operating block 210.

[0030] Reference Figure 2 and Figure 3 As shown, nuts 211 are provided on both sides of the circular hole plate 24. The outer surface of the first threaded rod 23 is threadedly connected to the inner walls of the two nuts 211. By providing two nuts 211, rotating the nuts 211 causes one side of the nuts 211 to abut against one side of the circular hole plate 24, thus fixing the circular hole plate 24 and the first threaded rod 23, and thus fixing the limiting plate 25, which helps to prevent the limiting plate 25 from shifting after adjustment. A rubber ring 212 is fixedly connected to the side of the nut 211 near the circular hole plate 24. The outer surface of the first threaded rod 23 is located inside the rubber ring 212. By providing the rubber ring 212, the friction between the nut 211 and the circular hole plate 24 can be increased, which helps to prevent the nut 211 from loosening.

[0031] Reference Figure 2 and Figure 4 As shown, the positioning device 3 includes an auxiliary plate 31, which is sleeved on the bottom of the outer surface of the base 1. Rectangular rods 32 are symmetrically fixedly connected to both sides of the auxiliary plate 31, and auxiliary blocks 33 are symmetrically fixedly connected to both sides of the base 1. The outer surface of the rectangular rods 32 is slidably connected to the inner wall of the auxiliary blocks 33, and bolts 34 are threaded into the inner wall of the auxiliary blocks 33. By setting the auxiliary plate 31, the auxiliary plate 31 is pushed to move in the vertical direction until the bottom of the auxiliary plate 31 abuts against the ground. Then, the bolts 34 are rotated so that one end of the bolts 34 abuts against one side of the rectangular rods 32, thus fixing the auxiliary plate 31. The auxiliary plate 31 can increase the friction between the base 1 and the ground, which helps to prevent the labeling device from easily shifting or tipping over.

[0032] Reference Figure 2 and Figure 4 As shown, an auxiliary groove 35 is provided on one side of the rectangular rod 32. A rubber strip 36 is fixedly connected to the inner wall of the auxiliary groove 35. By setting the rubber strip 36, the friction between one end of the bolt 34 and the rectangular rod 32 can be increased, making the bolt 34 more firmly fixed to the auxiliary plate 31.

[0033] A rectangular block 37 is fixedly connected to one end of the rectangular rod 32. By setting the rectangular block 37, one end of the rectangular rod 32 can be blocked, which helps to prevent the rectangular rod 32 from detaching from the inner wall of the auxiliary block 33 due to misoperation.

[0034] Working principle: Pushing the two limiting plates 25 causes the circular hole plate 24 to slide on the outer surface of the first threaded rod 23 until one side of the two limiting plates 25 is about to abut against the outer surface of the plastic cup on the conveyor belt 5. Rotating the two nuts 211 on both sides of the circular hole plate 24 causes the rubber ring 212 on one side of the nut 211 to abut against one side of the circular hole plate 24. The two nuts 211 can fix the circular hole plate 24 and the first threaded rod 23, thereby fixing the limiting plates 25. This helps to prevent the limiting plates 25 from shifting after adjustment. Then, rotating the four operating blocks 210 drives the four second threaded rods 27 to rotate respectively. The threaded rods will drive the slider 22 connected to the extension block 28 to move along the inner wall of the extension plate 21. As the slider 22 slides, it drives the first threaded rod 23 and the limiting plate 25 to move vertically until the limiting plate 25 no longer obstructs the labeling position on the plastic cup. The limiting plate 25 can block the plastic cup, which helps prevent the plastic cup from shifting on the conveyor belt 5 and causing the label to be applied crookedly, thereby improving the yield of plastic cups. The auxiliary plate 31 is pushed to move vertically until the bottom of the auxiliary plate 31 abuts against the ground. The bolt 34 is rotated so that one end of the bolt 34 abuts against the rubber ring 212 on one side of the rectangular rod 32, which can fix the auxiliary plate 31. The auxiliary plate 31 can increase the friction between the base 1 and the ground, which helps prevent the labeling device from easily shifting and tipping over.
