Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging equipment technology, and more specifically to a film material conveying mechanism for a heat transfer printing machine for applying film to square barrels. Background Technology
[0002] During the production process, a film needs to be applied to the surface of the square bucket to transfer the pattern. Traditionally, this process relies on manual operation: the transfer film is placed on the side wall of the bucket, and then the pattern is manually transferred to the bucket body using a transfer plate. This method not only has a low yield rate but also poses significant safety risks.
[0003] To improve production efficiency, traditional film transfer methods have been replaced by heat transfer machines. These machines place the film material onto the film-coating surface of a rectangular container, then apply heat using hot rollers. However, traditional heat transfer machines still require manual operation for film material feeding: after the container is positioned, the operator must manually crank the feeder to move the film material above the container before the heat rollers transfer it. Because the positioning of the film material relative to the container's film-coating surface relies on the operator's feel, deviations are prone to occur, which not only reduces transfer accuracy but also affects overall production efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a film material conveying mechanism for a heat transfer printing machine for applying film to square barrels, so as to solve the problems in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.
[0006] A film conveying mechanism for a heat transfer printing machine for applying film to square barrels includes a support plate vertically mounted above the heat transfer printing machine, a horizontal plate horizontally mounted on the support plate, a lifting bracket mounted below the horizontal plate, and a transfer film lifting cylinder mounted above the horizontal plate for driving the lifting bracket to move up and down. An unwinding roller and a rewinding roller are respectively mounted at both ends of the lifting bracket. Several guide rollers are arranged between the unwinding roller and the rewinding roller to guide the conveyed transfer film. Unwinding motors and rewinding motors for driving the unwinding roller and the rewinding roller to rotate are respectively mounted on the lifting bracket at the sides of the unwinding roller and the rewinding roller. An adjusting roller for adjusting the tension of the transfer film is mounted below the unwinding roller.
[0007] To further optimize the technical solution, several guide roller adjustment blocks are arranged opposite each other on both sides of the lifting bracket. A lead screw is threaded through the guide roller adjustment block. The two ends of the guide roller are respectively set at the bottom end of the lead screw through mounting blocks. An adjustment knob for adjusting the height of the guide roller is set at the top end of the lead screw.
[0008] To further optimize the technical solution, the lower end of the unwinding roller is provided with an adjusting roller mounting frame connected to the lifting bracket. The adjusting roller mounting frame has an adjusting groove, and both ends of the adjusting roller are set in the adjusting groove.
[0009] To further optimize the technical solution, a lead screw is inserted into the adjustment groove, a moving block is sleeved on the lead screw in the adjustment groove, the two ends of the adjustment roller are set on the moving block on the corresponding side, and an adjustment knob for adjusting the position of the adjustment roller is set on the outer top of the lead screw.
[0010] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.
[0011] This utility model provides a film conveying mechanism for a heat transfer printing machine for square barrel film application. By setting multiple guide rollers between the unwinding roller and the rewinding roller, the transfer film is tensioned and conveyed. During the transfer film conveying process, the tension of the transfer film can be finely adjusted by adjusting the rollers according to actual needs, thereby reducing the deviation of the transfer film conveying, improving the accuracy of square barrel film transfer and the efficiency of square barrel film application.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0015] A film material conveying mechanism for a heat transfer printing machine for applying film to square barrels, combined with Figure 1 As shown, it includes a support plate 1 vertically arranged above the heat transfer machine, a horizontal plate 2 arranged on the support plate 1, a lifting bracket 31 arranged below the horizontal plate 2, and a transfer film lifting cylinder 3 arranged above the horizontal plate 2. The end of the telescopic rod of the transfer film lifting cylinder passes through the horizontal plate and is connected to the top surface of the lifting bracket 31 to drive the lifting bracket to move up and down.
[0016] The lifting bracket 31 has an unwinding roller 32 and a take-up roller 33 at both ends to transport the transfer film 311. The lifting bracket at the side of the unwinding roller 32 and the take-up roller 33 is equipped with an unwinding motor and a take-up motor, respectively, to drive the unwinding roller to rotate and the take-up roller to rotate. The transfer film machine is equipped with a PLC controller. The input terminals of the unwinding motor and the take-up motor are connected to the output terminals of the PLC controller. The PLC controller controls the unwinding motor and the take-up motor, realizing the transport of the transfer film material during the operation of the transfer film machine.
[0017] Several guide rollers 34 are arranged between the unwinding roller and the rewinding roller to guide the conveyed transfer film. Several guide roller adjusting blocks 35 are arranged opposite each other on both sides of the lifting bracket 31. A lead screw 36 is threaded through the guide roller adjusting block 35. The two ends of the guide roller 34 are respectively mounted on the bottom end of the lead screw 36. An adjusting knob 310 is provided at the top of the lead screw 36 to adjust the height of the guide roller. By rotating the adjusting knob to adjust the height of the guide roller, the conveyed transfer film is supported, thereby realizing the conveying of the transfer film.
[0018] Below the unwinding roller 32 is an adjusting roller 39, which is used to adjust the tension of the transfer film. Below the unwinding roller 32 is an adjusting roller mounting frame 37 connected to the lifting bracket 31. The adjusting roller mounting frame 37 has an adjusting groove 38, and both ends of the adjusting roller 39 are set in the adjusting groove.
[0019] A lead screw 36 is inserted into the adjusting groove 38, and a moving block is fitted on the lead screw 36 in the adjusting groove. The two ends of the adjusting roller 39 are set on the moving blocks on the corresponding sides. An adjusting knob 310 is set on the outer top of the lead screw 36 to adjust the position of the adjusting roller, thereby realizing the adjustment of the tension of the transfer film.
[0020] In this invention, the transfer film is fed through the unwinding roller, then through the adjusting roller and the guide roller, and finally wound onto the take-up roller. The position of the guide roller is then adjusted to ensure the transfer film is conveyed under tension. During the transfer film conveying process, the position of the adjusting roller is adjusted by the adjusting knob on the side of the adjusting roller, thereby achieving fine-tuning of the tension of the transfer film. This realizes automatic conveying of the transfer film, thus improving the accuracy and efficiency of the transfer film application on square barrels.
