Description
Technical Field
[0001] This utility model relates to the field of labeling head technology, and in particular to a labeling head with a pressure-sensing structure. Background Technology
[0002] In the existing technological system, labeling devices play an indispensable role as an important piece of equipment widely used in the packaging of various products. However, in actual application, especially when dealing with labeling products of different thicknesses, these common labeling devices have exposed some obvious problems.
[0003] In existing technologies, the position of the labeling head is a crucial factor in labeling operations, directly determining the labeling pressure. The pressure applied to the label and product surface changes depending on the position of the labeling head, and this pressure variation significantly impacts the labeling effect. Excessive pressure can cause the label to deform, wrinkle, or even crack due to excessive compression. Conversely, insufficient pressure prevents the label from adhering tightly to the product surface, leading to issues like detachment and curling. In actual production, companies often handle products of varying thicknesses. Each time a different thickness is used for labeling, the labeling head position needs to be adjusted to achieve the appropriate pressure. Frequent adjustments to the labeling head position are inflexible, cumbersome, require skilled and experienced workers, and are time-consuming, significantly reducing production efficiency. Therefore, an improved labeling head with a pressure-sensing structure is needed to address these problems. Utility Model Content
[0004] To overcome the problem that the pressure applied to the label and product surface changes when the labeling head is in different positions, frequent adjustments are not flexible enough and are very cumbersome.
[0005] The technical solution of this utility model is as follows: a labeling head with a pressure sensing structure includes a working platform, a fixed bracket, and a conveying mechanism. A support base is fixedly connected to the bottom of the working platform. A conveying mechanism for conveying materials forward is provided on the working platform. A fixed bracket is fixedly connected to the working platform. A telescopic rod is fixedly connected to the fixed bracket. A connecting seat is fixedly connected to one end of the telescopic rod. The connecting seat is slidably connected to the fixed bracket. A labeling component for labeling is provided on the connecting seat. A pressure plate for pressing the label is fixedly connected to the labeling component. A connecting buckle is fixedly connected to the pressure plate. A guide block is fixedly connected to the connecting seat. A sliding block is slidably connected to the guide block. A fixed rod is fixedly connected to the sliding block. A connecting rod is fixedly connected between the fixed rod and the connecting buckle. A sensing block body is fixedly connected to the sliding block. A pressure sensor body for sensing pressure is provided on the connecting seat. A controller body for controlling the telescopic rod is provided on the connecting seat.
[0006] Preferably, the sliding block has a matching groove at the relative position of the guide block, and the sliding block is slidably connected to the guide block through the groove.
[0007] Preferably, the pressure sensor body is provided with a first connecting block, and the pressure sensor body is threaded with a fastening bolt for fastening the first connecting block. A second connecting block is fixedly connected to the connecting seat. The first connecting block is slidably connected inside the second connecting block. A push plate that pushes the first connecting block out is slidably connected inside the second connecting block. A first spring is fixedly connected between the push plate and the second connecting block. A sliding frame is slidably connected to the connecting seat. A second spring is fixedly connected between the sliding frame and the connecting seat. A pull ring is fixedly connected to one end of the sliding frame. A limiting block that limits the position of the first connecting block is fixedly connected to the sliding frame.
[0008] Preferably, the second connecting block has a groove at the relative position of the push plate, and the push plate is slidably connected inside the groove.
[0009] Preferably, the connecting seat has a groove at the relative position of the sliding frame, and the sliding frame is slidably connected inside the groove.
[0010] Preferably, the second connecting block has a groove at the position of the first connecting block, and the first connecting block is slidably connected inside the groove.
[0011] Preferably, the conveying mechanism includes a fixed plate, which is fixedly connected to the working platform. A first motor is fixedly connected to the fixed plate, and a conveyor wheel is fixedly connected to the output end of the first motor. The conveyor wheel is rotatably connected inside the working platform, and a conveyor belt for conveying materials forward is driven onto the conveyor wheel.
[0012] The beneficial effects of this utility model are:
[0013] 1. Compared to the traditional method of adjusting the labeling head position, this method uses the contact between the sensing block and the pressure sensor to sense the pressure difference in real time and transmits a signal to the controller to adjust the position of the labeling component and the pressure plate. This effectively avoids problems such as label breakage, poor adhesion, or product surface damage caused by excessive pressure, as well as label curling, falling off, or uneven adhesion caused by insufficient pressure. It ensures that each label adheres to the product surface in the best condition, and also greatly improves production efficiency, reduces rework and scrap rates caused by poor labeling. This avoids the problem that the pressure applied to the label and product surface changes when the labeling head is in different positions, which is inflexible and cumbersome due to frequent adjustments.
[0014] 2. Compared to the traditional method of fixing the pressure sensor body with bolts, the first connecting block and the second connecting block work together. During installation, the first connecting block is simply pressed into the second connecting block, and the first connecting block is restricted by the limiting block. This makes the overall installation quicker and more efficient. During disassembly, after the limiting block releases the restriction on the first connecting block, the first spring provides a pushing force to the push plate, pushing the first connecting block to make the pressure sensor body automatically pop out a short distance. At this time, the staff can quickly remove the pressure sensor body for inspection and maintenance, which greatly improves the convenience of maintenance work. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figure 1 - Figure 3This utility model provides an embodiment of a labeling head with a pressure-sensitive structure, including a working platform 1, a fixed bracket 21, and a conveying mechanism. A support base 4 is fixedly connected to the bottom of the working platform 1. A conveying mechanism for advancing materials is provided on the working platform 1. The fixed bracket 21 is fixedly connected to the working platform 1, and a telescopic rod 22 is fixedly connected to the fixed bracket 21. One end of the telescopic rod 22 is fixedly connected to a connecting seat 23, which is slidably connected to the fixed bracket 21. A labeling attachment is provided on the connecting seat 23. Labeling component 24, a pressure plate 25 for pressing labels is fixedly connected to the labeling component 24, a connecting buckle 26 is fixedly connected to the pressure plate 25, a guide block 27 is fixedly connected to the connecting seat 23, a sliding block 28 is slidably connected to the guide block 27, a fixing rod 29 is fixedly connected to the sliding block 28, a connecting rod 210 is fixedly connected between the fixing rod 29 and the connecting buckle 26, a sensing block body 211 is fixedly connected to the sliding block 28, a pressure sensor body 212 for sensing pressure is provided on the connecting seat 23, and a control mechanism for the telescopic rod 22 is provided on the connecting seat 23. The device body 213, specifically the pressure sensor body 212 (model SBT674) and the controller body 213 (model DVP32EH), in use, moves downward via the telescopic rod 22 pushing the connecting seat 23, and then the material is steadily conveyed forward by the conveying mechanism. Labeling is performed when the material passes the labeling component 24. The labeling component 24 is a common existing technology; therefore, its general working principle is that after placing the label roll on the material roll roller in the labeling component 24, it is passed around multiple guide rods in the labeling component 24. In use, the label passes through… The labeling process is performed at the pressure plate 25. After labeling, the backing paper is then collected by the recycling roller on the labeling assembly 24. The material comes into contact with the pressure plate 25, generating a reaction force. This force is transmitted to the fixed rod 29 via the connecting buckle 26 and the connecting rod 210, causing the sliding block 28 to slide upward. When the sliding block 28 slides upward, it comes into contact with the pressure sensor body 212 through the sensing block body 211, thereby sensing the pressure value and transmitting it to the controller body 213 for analysis. The controller body 213 then controls the extension and retraction of the telescopic rod 22 to adjust the pressure difference.
[0025] Please see Figure 1 - Figure 6In this embodiment, the sliding block 28 has a matching groove at a position relative to the guide block 27. The sliding block 28 is slidably connected to the guide block 27 through the groove. The groove cooperates with the guide block 27 to allow the sliding block 28 to slide linearly and avoid tilting, which would affect the contact between the sensing block body 211 and the pressure sensor body 212. The pressure sensor body 212 is provided with a first connecting block 214, and a fastening bolt 215 for fastening the first connecting block 214 is threadedly connected to the pressure sensor body 212. A second connecting block 21 is fixedly connected to the connecting seat 23. 6. The first connecting block 214 is slidably connected inside the second connecting block 216. Inside the second connecting block 216, a push plate 217 is slidably connected to push the first connecting block 214 out. A first spring 218 is fixedly connected between the push plate 217 and the second connecting block 216. A sliding frame 219 is slidably connected to the connecting seat 23. A second spring 220 is fixedly connected between the sliding frame 219 and the connecting seat 23. A pull ring 221 is fixedly connected to one end of the sliding frame 219. A limiting block 22, which limits the position of the first connecting block 214, is fixedly connected to the sliding frame 219. 2. The second spring 220 provides a pushing force to the sliding frame 219, pushing the limiting block 222 outward to more firmly restrict the sliding of the first connecting block 214, thereby limiting the position of the pressure sensor body 212. The second connecting block 216 has a groove at the relative position of the push plate 217, and the push plate 217 is slidably connected inside the groove. The groove restricts the sliding of the push plate 217, preventing the push plate 217 from affecting the subsequent sliding of the first connecting block 214. The connecting seat 23 has a groove at the relative position of the sliding frame 219, and the sliding frame 219 is slidably connected to the groove. Inside, the sliding frame 219 is restricted to slide by a groove to prevent it from tilting during sliding, which would affect the position of the limiting block 222 that restricts the first connecting block 214 and cause the subsequent sensing block body 211 to contact the pressure sensor body 212. The second connecting block 216 has a groove at the position of the first connecting block 214, and the first connecting block 214 is slidably connected inside the groove. The groove restricts the sliding of the first connecting block 214, and the subsequent sliding of the first connecting block 214 makes it easy for staff to quickly pick up the pressure sensor body 212 for maintenance and testing.
[0026] Please see Figure 2 , Figure 7 In this embodiment, the conveying mechanism includes a fixed plate 31, which is fixedly connected to the working platform 1. A first motor 32 is fixedly connected to the fixed plate 31, and a conveying wheel 33 is fixedly connected to the output end of the first motor 32. The conveying wheel 33 is rotatably connected inside the working platform 1, and a conveyor belt 34 for conveying materials is driven to the conveying wheel 33. The conveying mechanism steadily conveys the materials forward for labeling, thus avoiding the materials from moving too fast and affecting the labeling quality.
[0027] During operation, the telescopic rod 22 pushes the connecting seat 23 downward, and the first motor 32 drives the conveyor wheel 33 to rotate. When the conveyor wheel 33 rotates, the conveyor belt 34 steadily transports the material forward. When the material passes the labeling component 24, it is labeled. The material contacts the pressure plate 25, generating a reaction force. This force is transmitted through the connecting buckle 26 and the connecting rod 210 to the fixed rod 29, causing the sliding block 28 to slide upward. When the sliding block 28 slides upward, it contacts the pressure sensor body 212 through the sensing block body 211 to sense the pressure value and transmits the data to the controller body 213 for analysis. The controller body 213 then controls the telescopic rod 22 to extend and retract, thereby adjusting the pressure difference. For subsequent maintenance, the pull ring 221 is pulled. When moving outward, the sliding frame 219 moves outward, thereby causing the limiting block 222 to release the restriction on the first connecting block 214. At this time, the first spring 218 provides a pushing force to the push plate 217, pushing the push plate 217 to slide outward, thereby pushing the first connecting block 214 to pop outward, so that the staff can quickly remove the pressure sensor body 212 for maintenance and repair. After the maintenance is completed, the first connecting block 214 is aligned with the groove of the second connecting block 216 and slid in. After the first connecting block 214 pushes the push plate 217 to slide the second connecting block 216 back to the bottom of the groove opened at its relative position, the pull ring 221 is released. At this time, the second spring 220 provides a pushing force to the sliding frame 219, pushing the limiting block 222 to move back to its original position and restrict the first connecting block 214.
[0028] Through the above steps, compared with the traditional method of adjusting the labeling head position, the pressure difference is sensed in real time by the contact between the sensing block body 211 and the pressure sensor body 212, and the signal is transmitted to the controller body 213 to control the adjustment of the position of the labeling component 24 and the pressure plate 25. This solves the problem that the pressure applied to the label and product surface will change when the labeling head is in different positions, and frequent adjustment is not flexible and is very cumbersome.
