Abstract
Description
Technical Field
[0001] This utility model relates to a device for preventing trademark labels from shifting, and belongs to the technical field of trademark label processing equipment. Background Technology
[0002] After printing or manufacturing, trademark labels need to be cut. Because the labels are in a free state after cutting, they are prone to positional shifts. This can lead to misalignment during subsequent bending operations, resulting in defective products. Traditional trademark label cutting and bending machines use mechanical methods to fix the labels in place. However, since labels vary in size and length, the mechanical pressure feet need to be adjusted to align with the label's position. Furthermore, for smaller trademark labels, space constraints make it impossible to fix them securely, causing misalignment during the cutting process and resulting in a large number of defective products.
[0003] Therefore, the market urgently needs a device that can overcome the above problems and prevent trademark label displacement. Summary of the Invention
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a device to prevent trademark label displacement. This device does not require adjusting the position of the mechanical presser foot, is not limited by space, can effectively fix the label, and does not cause displacement.
[0005] A device for preventing trademark label displacement includes a cutting component for cutting the trademark label, a vacuum adsorption component disposed behind the cutting component, the vacuum adsorption component being installed on a label peeling platform, the vacuum adsorption component including a plurality of holes formed in the label peeling platform, a vacuum suction cup being installed below the label peeling platform, the bottom of the vacuum suction cup being connected to a vacuum generator through a pipeline, and the vacuum generator being controlled by an automatic controller.
[0006] Preferably, the vacuum suction cup and the label-removing platform are connected by bolts;
[0007] Preferably, the automatic controller is a PLC controller or a microcontroller;
[0008] Preferably, an air pipe connector is installed below the vacuum suction cup, and the air pipe connector is connected to the vacuum generator through a pipe;

[0010] Preferably, the cutting assembly includes two fixed shafts, a blade holder sliding seat, a blade holder mounting plate, a cutter, and a cam assembly. The two fixed shafts are partially disposed within the blade holder sliding seat, which contains two linear bearings that cooperate with the two fixed shafts. The blade holder mounting plate is mounted on the blade holder sliding seat, and the cutter is mounted on the blade holder mounting plate. The cam assembly drives the blade holder sliding seat to move up and down, which in turn drives the cutter to move up and down to cut the label. The cam assembly includes a cam rod with one end mounted on the blade holder sliding seat, and a camshaft at the other end. The camshaft is driven by a motor controlled by an automatic controller. When the camshaft rotates, it drives the cam rod to move up and down, which in turn drives the blade holder sliding seat to move up and down, and also drives the cutter to move up and down to cut the label.
[0011] This utility model discloses a device for preventing trademark label displacement. Its ingenious structural design eliminates the need for manual adjustment of the mechanical presser foot for label positioning, thus shortening machine setup time, saving raw materials, reducing worker workload, and preventing the waste of large amounts of raw materials and working time caused by repeated manual adjustments in existing technologies. Furthermore, it solves the problem of fixing smaller trademarks due to space limitations, and also addresses the issue of high defect rates caused by label misalignment during cutting.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figure 1-5This embodiment of a device for preventing trademark label displacement includes a cutting component 15 for cutting the trademark label, a vacuum adsorption component 16 disposed behind the cutting component 15, and the vacuum adsorption component is installed on a label peeling platform 1. The vacuum adsorption component includes several holes 2 formed on the label peeling platform 1, and a vacuum suction cup 3 is installed below the label peeling platform 1. The bottom of the vacuum suction cup 3 is connected to a vacuum generator 4 through a pipe 7. The vacuum generator is controlled by an automatic controller. The vacuum suction cup 3 is connected to the label peeling platform 1 by bolts 5. The automatic controller is a PLC controller. The holes 2 are composed of an upper sub-hole 2-1 and a lower sub-hole 2-2 arranged vertically, and the two sub-holes are vertically connected. The inner diameter of the upper sub-hole 2-1 is 0.8-1.5mm, the inner diameter of the lower sub-hole 2-2 is 3-5mm, the length of the lower sub-hole 2-2 is 7-9mm, and the length of the upper hole 2-1 is 0.8-1.5mm. Below the vacuum suction cup 3, there is an air pipe connector 6, which is connected to the vacuum generator 4 via a pipe 7. The special design of the hole 2 serves two purposes: first, it facilitates drilling, reducing processing difficulty and cost; second, it increases the suction force, firmly adhering to the trademark label.
[0019] The cutting assembly includes two fixed shafts 8, a blade holder sliding seat 9, a blade holder mounting plate 10, a cutter 11, and a cam assembly. The two fixed shafts 8 are partially disposed within the blade holder sliding seat 9, which contains two linear bearings that cooperate with the two fixed shafts 8. The blade holder mounting plate 10 is mounted on the blade holder sliding seat 9, and the cutter 11 is mounted on the blade holder mounting plate 10. The cam assembly drives the blade holder sliding seat 9 to move up and down, and also drives the cutter 11 to move up and down to cut the label. The cam assembly includes a cam rod 12 with one end mounted on the blade holder sliding seat 9, and a camshaft 13 at the other end. The camshaft 13 is driven by a motor controlled by an automatic controller. When the camshaft 13 rotates, it drives the cam rod 12 to move up and down, which in turn drives the blade holder sliding seat 13 to move up and down, and also drives the cutter 11 to move up and down to cut the label.
[0020] When the label 14 reaches the cutting position, the PLC controller powers the vacuum generator 4, creating a vacuum suction. The label 14 is then adsorbed onto the label peeling platform 1, and the cutting assembly 15 cuts off the label 14. At this point, due to the vacuum suction on the label peeling platform 1, the label 14 does not shift. After cutting, when the next process picks up the label 14, the PLC controller de-powers the vacuum generator 4, releasing the label 14 adsorbed on the label peeling platform 1 for further processing.
