Description

Technical Field

[0001] This utility model relates to the technical field of plastic film processing equipment, specifically a heat shrink printing film setting machine. Background Technology

[0002] Heat shrinkable printed films are widely used in food packaging, electronic product protection, and product display due to their excellent adhesion, moisture resistance, and high transparency. However, traditional heat shrinkable film setting processes suffer from problems such as low efficiency, uneven setting, and easy wrinkling, which affect the aesthetics and practicality of the products. Therefore, it is particularly important to develop a heat shrinkable printed film setting machine.

[0003] A heat-shrinkable printing film shaping structure, as described in reference announcement number CN214324262U, includes a main box, a re-fusion structure, a cutting structure, and a collecting structure. One side of the main box is detachably connected to the re-fusion structure, which is connected to a servo motor via a belt. One side of the cutting structure is detachably connected to the main box. The collecting structure is detachably connected to the outer surface of the main box. A support is provided below the main box. This heat-shrinkable printing film shaping structure utilizes the re-fusion structure, heating elements, and rotating heat-conducting rollers for uniform heating, ensuring that both rolls of heat-shrinkable printing film are evenly heated. The heat-shrinkable printed film can be fused into a single layer. A servo motor rotates, driving a belt that in turn drives a cold-shrinking roller to roll, thinning the fused film layer. This process of thinning and re-fusion of the heat-shrinkable printed film reduces the probability of defects, resulting in a higher yield and better product quality after shaping. However, while this shaping structure has good applications, it is generally not convenient for automatically cutting the wound film. Personnel must use tools to cut the film, which presents some inconvenience and requires further improvement. Utility Model Content

[0004] The purpose of this utility model is to provide a heat shrink printing film setting machine to solve the problem that although the setting structure proposed in the background art can be well applied, it is usually not convenient to automatically cut the wound film. The film needs to be cut by personnel with the help of tools, which is inconvenient during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat shrinkable printing film setting machine, comprising a base plate, a support seat on one side of the top of the base plate, a portal frame on the top of the base plate outside the support seat, a vertical plate on the top of the base plate on one side of the portal frame, a limiting rail on one side of the top of the portal frame, a linkage seat slidably connected to one side of the top of the limiting rail, an electric push rod installed on the top of the portal frame on one side of the limiting rail, one end of the electric push rod connected to the outer wall of the linkage seat, a component placement seat on the outer surface of one side of the linkage seat, the top of the component placement seat slidably connected to the top of the limiting rail, a lifting drive component installed on the inner wall at the lower end of the component placement seat, a knife holder at the bottom of the lifting drive component, a cutter installed at the bottom of the knife holder, and a cutting table at the top of the support seat below the cutter.

[0022] In use, the locking bolt 21 is used to allow the annular fastening sleeve 20 to be attached to or detached from the outer wall of the unwinding shaft 18.

[0023] A take-up roller 17 is rotatably mounted on the surface of the vertical plate 12 below the unwinding roller 19, a second guide roller 15 is rotatably mounted on the surface of the vertical plate 12 below the take-up roller 17, and two pressure rollers 16 are rotatably mounted on the surface of the vertical plate 12 on one side of the unwinding roller 19.

[0024] In use, the pressure roller 16 is set to roll and flatten the film;

[0025] A motor 14 is mounted on the surface of the vertical plate 12 below the pressure roller 16. One end of the motor 14 passes through the vertical plate 12 and is provided with a belt drive mechanism 26. The inner wall of the end of the belt drive mechanism 26 away from the motor 14 is connected to one end of the winding roller 17.

[0026] In use, the motor 14 is configured to drive the take-up roller 17 to rotate via the belt drive mechanism 26;

[0027] A limiting rail 4 is provided on one side of the top of the portal frame 2. A linkage seat 24 is slidably connected to one side of the top of the limiting rail 4. An electric push rod 3 is installed on the top of the portal frame 2 on one side of the limiting rail 4. One end of the electric push rod 3 is connected to the outer wall of the linkage seat 24. A placement seat 25 is provided on the outer surface of one side of the linkage seat 24. The top of the placement seat 25 is slidably connected to the top of the limiting rail 4. A lifting drive 5 is installed on the inner wall of the lower end of the placement seat 25. A knife seat 6 is provided at the bottom of the lifting drive 5. A cutter 7 is installed at the bottom of the knife seat 6. A cutting table 9 is provided at the top of the support seat 8 below the cutter 7. A heating box 10 is provided at the top of the support seat 8 on one side of the cutting table 9. A cold air blower 11 is installed on the outer wall of the heating box 10 away from the support seat 8. A first guide roller 13 is rotatably installed on the outer wall of the support seat 8 below the cold air blower 11 via a bracket.

[0028] In use, the first guide roller 13 is set to guide the film.

[0029] A heating tube 22 is installed on the top of the heating box 10, and a temperature sensor 23 is installed on the inner wall of the heating box 10 below the heating tube 22.

[0030] In use, the heating tube 22 is installed to heat the interior of the heating box 10.

[0031] In this embodiment, the unwinding roller 19 containing the heat-shrinkable printing film is first fitted onto the outer wall of the unwinding shaft 18. One end of the film wound on the outer wall of the unwinding roller 19 is inserted between two pressure rollers 16, and then sequentially passed under the heating box 10, the first guide roller 13, and the second guide roller 15 before being connected to the outer wall of the take-up roller 17. When the motor 14 drives the take-up roller 17 to rotate via the belt drive mechanism 26, the take-up roller 17 can perform the film winding process. During this process, the two pressure rollers 16 roll and shape the film in motion. Because the heating tube 22 heats the interior of the heating box 10, the film is heated and shaped when it enters the heating box 10, and cooled and shaped by the air cooler 11 when it exits the heating box 10, thus automating the winding and shaping of the film. Then, one end of the locking bolt 21 is screwed out to the outside of the unwinding shaft 18, and the annular fastening sleeve 20 is pulled. The unwinding roller 19 can be detached from the outer wall of the unwinding shaft 18 by pulling. If the unwinding roller 19 needs to be installed, the unwinding roller 19 and the annular fastening sleeve 20 are sequentially fitted onto the outer wall of the unwinding shaft 18. Then, the locking bolt 21 is tightened so that one end passes through the annular fastening sleeve 20 and is screwed into the outer wall of the unwinding shaft 18. This allows for easy installation and removal of the unwinding roller 19. Finally, the linkage seat 24 is driven by the electric push rod 3 to slide at the top of the limit rail 4, causing the linkage seat 24 to drive the placement seat 25 to move in the same direction at the top of the limit rail 4. This allows the placement seat 25 to move the cutter 7 horizontally above the cutting table 9. Then, the lifting drive 5 (i.e., the cylinder) drives the cutter seat 6 to move downward, allowing the cutter seat 6 to move the cutter 7 smoothly downward. The cutter 7 can then cut the film above the cutting table 9, thus completing the use of the setting machine.
