Description

Technical Field

[0001] This utility model relates to the field of laser transfer film technology, specifically to a laser transfer film tensile strength testing device. Background Technology

[0002] Laser transfer film is a widely used functional film that plays an important role in packaging, printing, and anti-counterfeiting. In the packaging industry, it can be used for the outer packaging of various products to enhance their visual appeal and grade. In the printing industry, it can achieve exquisite laser pattern printing effects. At the same time, its unique laser effect also makes it an important component of anti-counterfeiting technology, helping companies protect product brands and consumer rights.

[0003] In practical applications, laser transfer membranes may be subjected to multiple forces such as tension, pressure and friction at the same time. However, existing tensioning devices may only be able to perform tension tests alone, and cannot accurately apply pressure or simulate friction while stretching. This makes it difficult to accurately simulate the complex working conditions of the membrane in actual use, resulting in test results that cannot fully reflect the true performance of the membrane.

[0004] In view of this, this paper studies and improves upon existing problems, and provides a laser transfer film tensile strength testing device with reasonable structural design, high stability, and comprehensive application. The aim is to solve the problem and improve the practical value through this technology. Utility Model Content

This allows for the timely detection of problems in the production process, helping manufacturers to take corresponding measures to improve the product quality and stability, and reducing product damage or failure caused by insufficient compressive strength of the film material. This invention realizes a laser transfer film tensile strength testing device.

[0020] 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.

[0021] Reference Figure 1-4 An embodiment of this utility model provides a laser transfer film tensile strength testing device, comprising a base 1, a threaded rod 2 rotatably mounted inside the base 1, a fixed frame 4 fixedly connected to the upper end of the base 1, an air inlet pipe 5 mounted on the upper end of the fixed frame 4, a pressure plate 7 mounted on the lower end of the air inlet pipe 5, a reciprocating screw 8 connected to one end of the threaded rod 2, a piston 9 connected to the outside of the reciprocating screw 8, a guide pipe 10 mounted on the outside of the piston 9, a connecting pipe 11 connected to one end of the guide pipe 10, an air pipe 13 mounted on one side of the fixed frame 4, a slide 16 connected to the outside of the threaded rod 2, a grinding roller 17 connected inside the slide 16, a gear 18 mounted on one side of the slide 16, a rack 19 connected to the outside of the gear 18, and a pulley A20 connected to one end of the gear 18.

[0022] In an optional embodiment: a slot is provided inside the base 1, and the threaded rod 2 is located inside the slot. A motor 3 is fixedly connected to one end of the base 1, and the threaded rod 2 extends through the base 1 to the outside and is connected to the output end of the motor 3. Before using the equipment, one end of the laser transfer film is placed under the pressure plate 7, and the other end is fixed to the slide 16. When in use, the threaded rod 2 is rotated by the drive of the motor 3.

[0023] In an optional embodiment: one end of the threaded rod 2 is fixedly connected to the reciprocating screw 8, the piston 9 is connected to the ball nut pair of the reciprocating screw 8, the guide tube 10 is fixedly connected to the base 1, and the other end of the connecting tube 11 is fixedly connected to the air inlet pipe 5. When the threaded rod 2 rotates, it will synchronously drive the reciprocating screw 8 to rotate. When the reciprocating screw 8 rotates, it will drive the piston 9 to reciprocate, so that the piston 9 will continuously compress the air pressure and enter the interior of the connecting tube 11.

[0024] In an optional embodiment: the air intake pipe 5 is fixedly connected to two sets of fixtures 4 at the upper end. Each set of fixtures 4 is movably connected to a push rod 6. The push rod 6 extends through the fixtures 4 to the lower end and is fixedly connected to the pressure plate 7. After the air pressure enters the connecting pipe 11, the connecting pipe 11 will deliver the air pressure to the air intake pipe 5, so that the air intake pipe 5 will push the push rod 6 out. When the push rod 6 is pushed out, it will push the pressure plate 7 down, thereby fixing the laser transfer film.

[0025] In an optional embodiment: two sets of fixing plates 12 are fixedly connected to the upper end of the fixing frame 4. One end of the two sets of fixing plates 12 is fixedly connected to an air pipe 13. The upper end of the air pipe 13 is connected to a branch pipe, which is fixedly connected to a connecting pipe 11. A pressure rod 14 is movably connected inside the air pipe 13. One end of the pressure rod 14 is fixedly connected to a spring 15, and the other end of the spring 15 is connected to the inner wall of the air pipe 13. A slot is opened on the outer side of the pressure rod 14. After the push rod 6 can no longer descend, as the piston 9 continuously intakes air, the air pressure will enter the air pipe 13 through the branch pipe. After the air pressure enters the air pipe 13, the air pipe 13 will push out the pressure rod 14. After the pressure rod 14 is pushed out to a certain distance, the slot will contact the outside, and the slot will release the air pressure inside the air pipe 13. After the air pressure inside the air pipe 13 is released, the pressure rod 14 will gradually return to its original position by the force of the spring 15.

[0026] In an optional embodiment: Gear 18 is movably connected to one side of slide 16, and rack 19 is meshed with the outer side of gear 18. Rack 19 is fixedly connected to base 1. Pulley A20 is fixedly connected to one end of gear 18. Belt 21 is sleeved inside pulley A20. Pulley B22 is sleeved at the end of belt 21 away from pulley A20. A graduated groove is provided on one side of pulley A20. When threaded rod 2 rotates, it synchronously drives slide 16 to move, thereby stretching the laser transfer film. When slide 16 moves, the operator can judge the tensile force on the laser transfer film by the position of slide 16 and the graduated groove. At the same time, the pressure rod 14 pushes out the laser transfer film for testing. The compressive strength under different tensile conditions can be used to promptly identify problems in the production process of the laser transfer film, such as uneven material distribution or imperfect processing technology. This helps manufacturers take corresponding measures to improve the product's quality and stability, and reduce product damage or failure caused by insufficient compressive strength of the film material. At the same time, when the slide 16 moves, it will synchronously drive the gear 18 to move. When the gear 18 moves, it will contact the rack 19, and the gear 18 will rotate through the rack 19. When the gear 18 rotates, it will synchronously drive the pulley A20 to rotate, and when the pulley A20 rotates, it will synchronously drive the pulley B22 to rotate through the belt 21.

[0027] In an optional embodiment: the slide 16 is threaded to the outside of the threaded rod 2, and a grinding roller 17 is movably connected inside the slide 16. A connecting rod is fixedly connected to one end of the grinding roller 17. The connecting rod extends through the slide 16 to the outside and is fixedly connected to the slide 16. When the pulley B22 rotates, the grinding roller 17 will be driven to rotate synchronously through the connecting rod. This allows for simultaneous detection of the wear resistance of the laser transfer film during stretching, preventing the laser transfer film from being subjected to friction under stretching. Synchronous detection can more accurately simulate this complex working condition, comprehensively evaluate the performance of the laser transfer film under the combined action of multiple stresses, avoid the disconnect between single detection conditions and actual use, and thus accurately grasp its durability in the real environment.

[0028] Working principle and process: Before using the equipment, place one end of the laser transfer film under the pressure plate 7 and fix the other end to the slide 16. During use, the threaded rod 2 is driven by the motor 3 to rotate. When the threaded rod 2 rotates, it will drive the reciprocating screw 8 to rotate synchronously. When the reciprocating screw 8 rotates, it will drive the piston 9 to move back and forth. Thus, the piston 9 will continuously compress the air pressure into the connecting pipe 11. After the air pressure enters the connecting pipe 11, the connecting pipe 11 will deliver the air pressure to the air inlet pipe 5. Thus, the air inlet pipe 5 will push out the push rod 6. When the push rod 6 is pushed out, it will push the pressure plate 7 down, thereby fixing the laser transfer film.

[0029] After the push rod 6 fails to descend, as the piston 9 continues to intake air, the air pressure will enter the air pipe 13 through the branch pipe. After the air pressure enters the air pipe 13, the air pipe 13 will push out the pressure rod 14. After the pressure rod 14 is pushed out to a certain distance, the empty slot will come into contact with the outside, and the empty slot will release the air pressure inside the air pipe 13. After the air pressure inside the air pipe 13 is released, the pressure rod 14 will gradually return to its original position by the force of the spring 15.

[0030] When the threaded rod 2 rotates, it synchronously drives the slide 16 to move, thereby stretching the laser transfer film. When the slide 16 moves, the operator can judge the tensile force on the laser transfer film by the position of the slide 16 and the scale groove. At the same time, the pressure rod 14 pushes out to test the compressive strength of the laser transfer film under different tensile conditions. Simultaneously, when the slide 16 moves, it synchronously drives the gear 18 to move. When the gear 18 moves, it will contact the rack 19, and the gear 18 will rotate through the rack 19. When the gear 18 rotates, it synchronously drives the pulley A20 to rotate. When the pulley A20 rotates, it synchronously drives the pulley B22 to rotate through the belt 21. When the pulley B22 rotates, it synchronously drives the grinding roller 17 to rotate through the connecting rod, thereby simultaneously testing the wear resistance of the laser transfer film during stretching.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
