Description

Technical Field

[0001] This application relates to the field of label composite equipment technology, specifically a label transposition device. Background Technology

[0002] In the field of electronic tag manufacturing, ultrasonic lamination technology is widely used to laminate chips with upper and lower film materials.

[0003] An existing patent (publication number: CN209159099U) discloses an ultrasonic electronic tag laminating machine. This machine includes a machine base, an ultrasonic laminating mechanism mounted above the machine base, a laminating roller mounted above the ultrasonic laminating mechanism, three feeding rollers on the left side of the machine base, and a receiving roller on the right side of the machine base. The ultrasonic laminating mechanism includes a laminating table, an ultrasonic generator positioned at the center of the bottom of the laminating table, and countersunk through holes at the four corners of the laminating table. Guide rods with shoulders are installed within these countersunk through holes. The bottom of the guide rods is threaded to the machine base, and springs are fitted onto the guide rods. The springs are positioned between the upper surface of the machine base and the lower surface of the laminating table, and are always under compression, ensuring that the upper surface of the laminating table is in close contact with the bottom of the laminating roller.

[0004] However, all three feeding rollers in the above equipment are fixedly installed. When it is necessary to adjust the composite position of the chip and the film material, such as to adapt to different chip sizes or adjust the label layout, the feeding rollers must be repositioned mechanically. This is complicated and the accuracy is difficult to guarantee. In addition, the feeding rollers of the laminating machine cannot be adaptively adjusted according to the width of the material strip, which makes the material strip prone to deviation during the conveying process, affecting the lamination accuracy. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a label switching device that has advantages such as easy adjustment and switching, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a label switching device, including a fixing plate, four material roller assemblies are respectively arranged on the front side of the fixing plate, and a composite assembly is arranged on the front side of the fixing plate, wherein three material roller assemblies are located on the left side of the fixing plate and one material roller assembly is located on the right side of the composite assembly; The material roller assembly includes a rotating shaft, the rear end of which is rotatably connected to a fixed plate. A drive cavity is provided inside the rotating shaft. A lead screw is rotatably connected between the front and rear inner walls of the drive cavity. The lead screw is coaxial with the rotating shaft. A drive block is threadedly connected to the outer surface of the lead screw. The drive block is slidably connected to the drive cavity. A movable cylinder is fixedly connected to the outer surface of the drive block. Two limiting rings are slidably sleeved on the outer surface of the movable cylinder along its axis.

[0007] Furthermore, a set of motors is mounted on the back of the fixing plate, and the output end of each motor is fixedly connected to the rear end of its adjacent rotating shaft.

[0008] The above scheme uses a motor to drive the rotating shaft to rotate and transport the material belt, while simultaneously providing rotational power to the lead screw, enabling the moving cylinder to move precisely along the shaft axis and achieve dynamic adjustment of the material belt position.

[0009] Furthermore, the material roller assembly also includes a positioning ring, which is fixedly connected to the outer surface of the rear end of the rotating shaft. Both the outer surface of the positioning ring and the rear end of the moving cylinder are equipped with through-beam ranging sensors, and the two through-beam ranging sensors are optically connected.

[0010] The above method allows for real-time monitoring of the axial displacement of the moving cylinder relative to the positioning ring, ensuring the adjustment accuracy of the moving cylinder and guaranteeing the alignment accuracy between the chip and the film material.

[0011] Furthermore, a coaxial mounting ring is fixedly connected to the front end of the rotating shaft, and a motor is mounted on the front side of the mounting ring. The output end of the motor is fixedly connected to the front end of the rotating shaft adjacent to it.

[0012] The above solution can provide power for the rotation of the lead screw.

[0013] Furthermore, a set of fixing holes arranged along its axial direction are provided on the outer surface of the movable cylinder, and the limiting ring is fixedly connected to its adjacent fixing holes by bolts.

[0014] The above solution allows for rapid adjustment of the spacing between the two limiting rings based on the width of the conveyor belt, adapting to the limiting requirements of conveyor belts of different specifications and effectively preventing lateral deviation during conveyor belt transport.

[0015] Furthermore, the composite component includes a composite roller and a composite plate. The rear end of the composite roller is rotatably connected to a fixed plate. The composite plate is located below the composite roller and its rear end is fixedly connected to the fixed plate. An ultrasonic generator is arranged above the composite plate, and a lifting plate is arranged below the ultrasonic generator. A pressure sensor is installed between the lifting plate and the ultrasonic generator, and an electromagnetic spring is installed between the lifting plate and the composite plate.

[0016] The above scheme, through the setting of electromagnetic springs and pressure sensors, enables adaptive pressure adjustment for strips of different thicknesses. When the pressure sensor detects that the actual pressure value deviates from the set value, the control system automatically adjusts the electromagnetic force of the electromagnetic spring to ensure stable composite pressure.

[0017] Furthermore, two guide rods are fixedly connected to the bottom of the lifting plate, and both guide rods are slidably inserted into the composite plate.

[0018] The above solution ensures that the lifting platform moves stably in the vertical direction, avoiding tilting of the lifting platform due to uneven pressure.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects: This label switching device drives the moving cylinder to move axially via a lead screw, and combined with the detection feedback from a distance sensor, it achieves precise adjustment of the material conveying position. At the same time, through the setting of limit rings and fixing holes, it can quickly adapt to the adjustment needs of different sized chips or label layouts, solving the problems of complex operation and low precision of traditional fixed feeding rollers. The combination design of the limiting ring and fixing hole allows for quick adjustment of the limiting distance according to the width of the material strip, effectively preventing the material strip from shifting laterally during the conveying process and ensuring the accuracy of the composite alignment. The coordinated work of the electromagnetic spring and pressure sensor can monitor and automatically adjust the composite pressure in real time to adapt to the composite requirements of material strips of different thicknesses, avoiding the problem of uneven pressure or damage caused by the traditional spring pre-compression method.

By driving the drive block 204 through the lead screw 203 to drive the movable cylinder 205 to move axially, the position of the material strip can be adjusted, thereby adjusting the reset position of the chip and the film material, and realizing the purpose of chip repositioning.

[0025] The material roller assembly 2 also includes a positioning ring 207, which is fixedly connected to the outer surface of the rear end of the rotating shaft 201. Both the outer surface of the positioning ring 207 and the rear end of the moving cylinder 205 are equipped with through-beam ranging sensors 208.

A set of motors 4 is installed on the back of the fixing plate 1. The output end of each motor 4 is fixedly connected to the rear end of its adjacent rotating shaft 201. The motors 4 drive the rotating shaft 201 to rotate, thereby conveying the material belt and simultaneously lifting the lead screw 203. The rotating cylinder 205 is powered to move precisely along the axis of the rotating shaft 201, enabling dynamic adjustment of the material belt position. A coaxial mounting ring 210 is fixedly connected to the front end of the rotating shaft 201. A motor 211 is mounted on the front side of the mounting ring 210.

[0026] The composite component 3 includes a composite roller 301 and a composite plate 302. The rear end of the composite roller 301 is rotatably connected to the fixed plate 1. The composite plate 302 is located below the composite roller 301, and its rear end is fixedly connected to the fixed plate 1. An ultrasonic generator 303 is disposed above the composite plate 302. The ultrasonic generator 303 and the composite roller 301 are existing technologies and will not be described in detail here. A lifting plate 304 is disposed below the ultrasonic generator 303. A pressure sensor 305 is installed between the lifting plate 304 and the ultrasonic generator 303. An electromagnetic spring 306 is installed between the lifting plate 304 and the composite plate 302. Through the setting of the electromagnetic spring 306 and the pressure sensor 305, adaptive pressure adjustment can be achieved for material strips of different thicknesses.

Two guide rods 307 are fixedly connected to the bottom of the lifting plate 304. Both guide rods 307 are slidably inserted into the composite plate 302 to ensure that the lifting plate 304 moves stably in the vertical direction and avoids tilting of the lifting plate 304 due to uneven pressure.

[0027] The working principle of the above embodiment is as follows: the upper film strip, chip strip, and lower film strip are respectively fitted onto the outer surface of the moving cylinder 205 of the three material roller assemblies 2 on the left. The composite strip is fitted onto the moving cylinder 205 of the right material roller assembly 2. According to the width of the strip, the distance between the two limiting rings 206 on the moving cylinder 205 is adjusted. The fixing bolts of the limiting rings 206 are loosened, and the limiting rings 206 are slid along the axial direction of the moving cylinder 205 to a suitable position. The bolts are inserted into the corresponding fixing holes 212 on the surface of the moving cylinder 205 to lock the limiting rings 206. 06. After completing the limit positioning on both sides of the conveyor belt to prevent conveying deviation, start the motor 4 on the back of the fixing plate 1. The output end of the motor 4 drives the rotating shaft 201 to rotate, driving the moving cylinder 205 and the conveyor belt to the direction of the composite component 3. The motor 211 on the mounting ring 210 at the front end of the rotating shaft 201 starts synchronously, driving the lead screw 203 to rotate. Through the threaded transmission of the lead screw 203 and the drive block 204, the moving cylinder 205 is driven to make a fine adjustment of its position along the axial direction of the rotating shaft 201 to ensure the initial alignment accuracy of the upper film, chip, and lower film. When it is necessary to adjust the chip and film... When the material is in composite position, the target displacement is input through the control system. The motor 211 drives the lead screw 203 to rotate, and the drive block 204 drives the moving cylinder 205 to move axially along the rotating shaft 201 to adjust the position of the material strip. The through-beam distance sensor 208 on the positioning ring 207 monitors the distance between the rear end of the moving cylinder 205 and the positioning ring 207 in real time to ensure the adjustment accuracy of the moving cylinder 205. The three layers of material strip are conveyed to the composite plate 302 and the composite roller 301 of the composite component 3. The ultrasonic generator 303 is started to generate high-frequency vibration. The film material is melted and bonded. Pressure sensor 305 detects the pressure value between lifting plate 304 and ultrasonic generator 303 in real time. If the pressure deviates from the set value, the control system adjusts the electromagnetic force of electromagnetic spring 306 to push lifting plate 304 to move vertically along guide rod 307 to compensate for the pressure deviation. Guide rod 307 ensures stable lifting of lifting plate 304 to avoid uneven bonding caused by tilting. The bonded strip is wound up by moving cylinder 205 of right roller assembly 2. Motor 4 drives rotating shaft 201 to rotate, completing the continuous production of labels.
