Description

Technical Field

[0001] The utility model relates to the technical field of heat laminating, in particular to temperature-controllable hot-pressing laminating equipment. Background Art

[0002] A thermal laminator is a widely used laminating machine, consisting of three parts: gluing, drying, and hot pressing. While commonly used for laminating large quantities of printed materials, it can also be used for laminating small batches of scattered printed materials, such as automated desktop office systems. During the laminating process, the thermal laminating rollers typically need to be heated to achieve the desired laminating effect. Heating increases the surface temperature of the thermal laminating rollers. When the plastic film comes into contact with the rollers, it becomes softer and more ductile, allowing it to adhere more tightly to the printed surface, improving the quality and durability of the lamination.

[0003] Existing heat-covering roller heating usually adds a heating rod to the heat-covering roller to achieve the heating effect of the heat-covering roller. However, the continuous heating of the heating rod will cause the heat in the heat-covering roller to continue to rise, and it cannot be stably maintained within a certain range. If the temperature of the heat-covering roller is too high, the film will cause problems such as wrinkles and discoloration. The existing heat-covering roller cooling method relies solely on natural cooling, which is inefficient. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 The top surface of the base 1 is rotatably connected to the unwinding roller 2, and the top surface of the base 1 is rotatably connected to two guide rollers 3, and the hot coating roller 4 is located between the two guide rollers 3, and the height of the two sides of the film is limited by the two guide rollers 3, so as to facilitate the hot coating roller 4 to heat the paper material. Two fixed frames 5 are symmetrically installed on the top surface of the base 1, and a lifting mechanism is installed in each fixed frame 5. The two lifting mechanisms are rotatably connected to the hot coating roller 4. The lifting mechanism includes two assembly seats 6, and each assembly seat 6 is slidably connected to the fixed frame 5 corresponding in position. Each fixed frame 5 is threadedly connected to a threaded pin 7, and the other end of each threaded pin 7 is rotatably connected to the assembly seat 6 corresponding in position, and each end of the hot coating roller 4 is rotatably connected to the side of the assembly seat 6 corresponding in position. It is worth noting that by twisting the threaded pin 7, the height of the threaded pin 7 in the fixed frame 5 is changed, and the position of the assembly seat 6 is changed, so as to facilitate the height adjustment of the hot coating roller 4 according to paper materials of different thicknesses;

[0023] An L-shaped bracket 9 is fixedly installed on the outside of one of the lifting mechanisms. A motor 8 is fixedly installed on the outside of the L-shaped bracket 9, and the output shaft of the motor 8 is connected to the heat-coating roller 4. The motor 8 is connected to a reciprocating screw 12 through a synchronization mechanism. The synchronization mechanism includes two synchronization wheels 10, and the two synchronization wheels 10 are respectively installed on the output shaft of the motor 8 and the reciprocating screw 12. The two synchronization wheels 10 are jointly covered with a synchronization belt 11. The synchronization mechanism can reduce the use of the motor 8, thereby saving the manufacturing cost of the device.

[0024] The bottom wall of the base 1 is fixedly mounted with a water pumping box 13 and a water storage box 14, and the reciprocating screw 12 is rotatably connected to the water pumping box 13. A water pumping mechanism is provided in the water pumping box 13, and the water pumping mechanism drives the reciprocating screw 12 to drive the water pumping mechanism including a screw sleeve 17, and the screw sleeve 17 is threadedly connected to the reciprocating screw 12. A piston 18 is installed on the outside of the screw sleeve 17 through a plurality of extension columns, and the screw sleeve 17 and the piston 18 are both slidably connected to the water pumping box 13. The internal cavity of the water pumping box 13 is a square cavity, and the screw sleeve 17 and the piston 18 are both slidably connected in the square cavity. A baffle 19 is fixedly buried at one end of the reciprocating screw 12 away from the synchronous wheel 10. It is worth noting that the screw sleeve 17 is limited by the square cavity, so that the screw sleeve 17 cannot rotate and can only perform linear reciprocating movement, and the baffle 19 facilitates the limitation of the screw sleeve 17 so that it cannot separate from the reciprocating screw 12;

[0025] The pumping box 13 is connected to the water storage tank 14 through the connecting pipe 20, the pumping box 13 is connected to the hot coating roller 4 through the water supply pipe 15, the hot coating roller 4 is connected to the hot coating roller 4 through the return pipe 16, the water supply pipe 15 and the connecting pipe 20 are both equipped with a one-way valve, the connecting pipe 20 is equipped with a hot and cold integrated machine 21, the hot coating roller 4 is fixedly installed with a partition 22, the partition 22 is provided with a through groove 23 at one end away from the water supply pipe 15, it is worth noting that through the water supply pipe 15, the hot coating roller 4 is connected to the hot coating roller 4 through the return pipe 16 ... One-way valves are installed in the pipe 15 and the connecting pipe 20, so that the flow direction of the water in the pipe is fixed. Through the reciprocating sliding of the piston 18, the water in the water storage tank 14 enters the water pumping tank 13 through the connecting pipe 20, and then the water in the water pumping tank 13 enters the heat-coated roller 4 through the water supply pipe 15. At the same time, through the setting of the partition 22, after the water flows into the heat-coated roller 4, it will first fill the heat-coated roller 4, and then enter the water storage tank 14 through the return pipe 16 to complete the self-circulation.

[0026] When the utility model is used, the film on the unwinding roller 2 is first passed through the bottom surface of the guide roller 3 and the bottom surface of the heat-covering roller 4. At the same time, the threaded pin 7 can be screwed to drive the position of the heat-covering roller 4 to rise and fall through the cooperation of the assembly seat 6, so as to facilitate heat-covering according to paper materials of different thicknesses;

[0027] Then the unwinding roller 2 and the conveyor belt on the top surface of the base 1 can be started, and the motor 8 drives the heat coating roller 4 to rotate, and then pushes the paper and film to be heat coated, and drives the reciprocating screw 12 to rotate through the synchronization mechanism. Through the cooperation of the screw sleeve 17 and the piston 18, the piston 18 can be driven to slide back and forth in the water pumping box 13, and then the water source in the water storage tank 14 is extracted through the connecting pipe 20, and transmitted to the heat coating roller 4 through the water supply pipe 15. Through the setting of the partition 22 and the through groove 23, the water source in the water storage tank 14 is extracted through the connecting pipe 20, and transmitted to the heat coating roller 4 through the water supply pipe 15. The water source fills the heat-covering roller 4 and eventually flows back to the water storage tank 14 through the return pipe 16. The water source in the water storage tank 14 can be heated or cooled by the integrated cold and hot machine 21 installed in the water storage tank 14. After being transported to the heat-covering roller 4, the temperature of the heat-covering roller 4 can be adjusted by the temperature of the water source, thereby achieving the effect of regulating the temperature of the heat-covering roller 4, so that the temperature of the heat-covering roller 4 is maintained in a constant range, avoiding the temperature of the heat-covering roller 4 being too high or too cold, which has an adverse effect on the heat covering.

[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
