Description

Technical Field

[0001] This utility model relates to the field of printer film splicing, and more particularly to a film splicing device for a heat press machine. Background Technology

[0002] A heat press machine works by covering a substrate (such as cotton, linen, polyester, leather, etc.) with a pre-designed transfer paper or heat transfer film. The heating plate releases a stable high temperature (usually adjustable between 100℃ and 220℃) and controllable pressure, causing the ink or adhesive layer in the transfer material to melt and penetrate into the fibers of the substrate within a short time (a few seconds to tens of seconds). After cooling, a vibrant, clear, and strongly adhesive printed effect is achieved. For details, please refer to the principle of the heat press machine described in patent application number CN202221402965.X. During operation, heat press machines sometimes fail to fully print the product after unwinding a roll of heat transfer media, or the remaining amount of media is insufficient after printing. This results in inefficient use of the heat transfer media, hindering cost control. Furthermore, it requires stopping the machine to remove unprinted products and perform rewinding and film rewinding, making the operation cumbersome and limiting the efficiency of heat press printing.

[0024] Example 1, see appendix Figures 1-6 A heat press machine film application device includes a base 1, a film pressing mechanism, and a synchronization rod 3. The base 1 has an inverted V-shaped seat 11 on its surface, and a lower silicone pad 12 on its surface. The length of the lower silicone pad 12 is the same as the length of the V-shaped seat 11. A heating wire 13 is provided on the surface of the lower silicone pad 12, and positive and negative terminals are respectively provided at both ends of the heating wire 13. Support plates 14 are provided at both ends of the base 1. The film pressing mechanism includes a pressure beam 21, a T-shaped plate 22, and an upper silicone pad 24. The upper silicone pad 24 is fixed to the bottom surface of the T-shaped plate 22, and the T-shaped plate 22 is evenly distributed with… Several elongated holes 221 are provided. A limiting shaft 25 is provided on the pressure beam 21, which passes through the elongated holes 221. Several springs 26 are evenly provided inside the pressure beam 21 and supported on the T-shaped plate 22. The springs 26 generate elastic pressure on the T-shaped plate 22. Both ends of the synchronizing rod 3 are provided with handles 31. One end of the end cover plate 32 of the synchronizing rod 3 is hinged to the top of the support plate 14, and the other end is hinged to the upper connecting rod 33. The lower end of the upper connecting rod 33 is hinged to the end face of the pressure beam 21. The end face of the pressure beam 21 is hinged to the lower connecting rod 27. The other end of the lower connecting rod 27 is hinged to the middle corner of the support plate 14.

[0025] The principle of the lamination mechanism is as follows: the synchronous rod 3 is pressed down by the handle 31, and the synchronous rod 3 pushes the cover beam 21 downward through the upper connecting rod 33. Under the support of the lower connecting rod 27 of the cover beam 21, it moves downward. The upper silicone pad 24 on the T-shaped plate 22 moves downward. When the upper silicone pad 24 and the lower silicone pad 12 come into contact, the reaction force of the upper silicone pad 24 will drive the T-shaped plate 22 to move upward and compress the spring 26. At the same time, the limiting shaft 25 slides in the elongated hole 221 to provide movement limit for the T-shaped plate 22. This rebound design is used to reduce the contact impact force between the upper silicone pad 24 and the lower silicone pad 12, ensuring that the heat transfer medium can be slowly subjected to pressure, which is conducive to improving the lamination quality.

[0026] A heat-insulating cloth 15 is covered between the surfaces on both sides of the V-shaped seat 11 and the surface of the heating wire 13. The heat-insulating cloth 15 provides a buffer for the pressure, ensures that the pressure is evenly distributed, and enables more uniform heat transfer, thereby improving the heat fusion welding effect.

[0027] Both sides of the V-shaped seat 11 are connected to pressure plates 16 by screws. The pressure plates 16 press against the surface of the heat insulation cloth 15. The edges of the pressure plates 16 are chamfered to reduce the friction when the heat transfer medium passes through.

[0028] The bottom surface of the T-shaped plate 22 is provided with a T-shaped groove 223, and the upper silicone pad 24 is matched and snapped into the T-shaped groove 223. This socket structure makes it easy to install the upper silicone pad 24 and provides high fixation after installation. The middle part of the V-shaped seat 11 is provided with a buckle plate 17, and the lower silicone pad 12 is snapped between the two side plates of the buckle plate 17. The buckle plate 17 forms a slot structure on the V-shaped seat 11, making it easy to install, remove and replace the lower silicone pad 12.

[0029] When using the heat transfer printing machine's film splicing device, the heat transfer medium is placed on the heat insulation cloth 15 on the surface of the V-shaped seat 11. The upper silicone pad 24 is pressed down by the film pressing mechanism, and the upper silicone pad 24 and the lower silicone pad 12 on the V-shaped seat 11 are attached. At the same time, the heating wire 13 on the lower silicone pad 12 melts the joint of the heat transfer medium through the heat insulation cloth 15. The pressure of the upper and lower silicone pads 12 makes the joint fuse together, realizing the connection between the heat transfer mediums. This avoids the phenomenon of the heat transfer medium material not being fully utilized, resulting in material waste. After splicing, there is no need to stop the machine to change the roll and pull the film, which simplifies the operation process and can effectively improve the efficiency of heat transfer printing.

[0030] Example 2, see appendix Figure 3This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the lower end of the lower connecting rod 27 is provided with a hanging ear, and a reset spring 4 is attached to the hanging ear. The lower end of the reset spring 4 is attached to the hanging ear on the base 1. After the lower pressing film mechanism achieves film application, the handle 31 is released. At this time, the elasticity of the reset spring 26 pulls the end of the lower connecting rod 27, and the lower connecting rod 27 rotates upward to drive the pressing film mechanism to rise. At the same time, the upper pull rod generates linkage and drives the synchronous rod 3 to rise, so as to realize the reset of the heat press machine film application device after film application.

[0031] A micro switch is provided on the lower inner side of the support plate 14. The contacts of the micro switch correspond to the bottom surface of the lower connecting rod 27. After the pressing mechanism is pressed down into place, the lower connecting rod 27 triggers the micro switch. The micro switch gives a signal, and the heating wire 13 starts to be energized to heat the heat transfer medium.

[0032] Example 3, see appendix Figure 6 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: several guide plates 23 are evenly provided inside the pressure beam 21, and a guide groove 231 is provided in the middle of the guide plate 23. The T-shaped plate 22 is slidably sleeved in the guide groove 231. The guide groove 231 in the guide plate 23 provides sliding guidance for the T-shaped plate 22, so that it always slides perpendicularly to the top plate of the pressure beam 21, avoiding the phenomenon of offset and misalignment, and ensuring the accuracy of membrane splicing.

[0033] The top plate of the cap beam 21 is provided with positioning posts 28. The T-shaped plate 22 is provided with a notch to form a positioning tongue 222. The two ends of the spring 26 are fitted between the positioning posts 28 and the positioning tongue 222. The positioning posts 28 and the positioning tongue 222 position and support the spring 26, preventing the spring 26 from bending, deforming or even misaligning, and ensuring its elastic pressing effect and rebound effect on the T-shaped plate 22.
