Description

Technical Field

[0001] This invention relates to the field of heat transfer technology, and in particular to an environmentally friendly heat transfer device for green and environmentally friendly printing. Background Technology

[0002] Heat transfer printing is an emerging printing technology. The printing process is divided into two main parts: transfer film printing and transfer processing. Transfer film printing uses halftone printing to pre-print the pattern on the surface of a thin film. The printed pattern has rich layers, bright colors, and is highly variable with small color difference and good reproducibility. It can meet the requirements of the designer and is suitable for mass production.

[0003] In existing technologies, waste gas is generated during the heat transfer process. Direct emission of this waste gas will affect the surrounding environment and is detrimental to environmental protection. At the same time, inhalation by operators will also have an impact on their health. Furthermore, the main problems with common heat transfer equipment components in existing technologies are that their overall structure has many components and is complex, and the disassembly and assembly of multiple components is troublesome, resulting in very poor overall ease of use of the device. Therefore, it is necessary to improve upon the above problems and redesign an environmentally friendly heat transfer device for green and environmentally friendly printing. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an environmentally friendly heat transfer device for green and environmentally friendly printing. This device features a protective cover with a dust collection hood inside, along with a reciprocating screw that works in conjunction with the protective cover. During processing, the dust collection hood, which can be easily moved, absorbs and treats the processing exhaust gas. It has a certain range of movement to ensure effective dust collection and prevents the direct emission of exhaust gas from affecting the environment and operators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An environmentally friendly heat transfer device for green printing includes a crossbar, a processing roller, and a protective cover. Two support frames are fixedly mounted below the crossbar via a fixing mechanism. A movable groove is provided on one outer wall of the crossbar, and a movable screw is rotatably mounted within the movable groove. The processing roller is connected to the movable screw via the movable mechanism. A drive motor is located above the crossbar, and a welding ring is welded to the outside of the drive motor. A movable groove is provided on the upper end face of the crossbar, and the welding ring engages with the movable groove via a movable mechanism. A support plate is fixedly mounted on the bottom wall of the crossbar. The support plate is L-shaped and has two lifting grooves, each containing a lifting screw. A placement plate is provided below the working roller. The placement plate is connected to two lifting screws through a connecting mechanism. A transmission chamber is provided inside the support plate. The ends of the lifting screws extend into the transmission chamber and are connected and cooperated through a rotating mechanism. A lifting motor connected and cooperated with one of the lifting screws is provided on the bottom wall of the transmission chamber. Two winding rollers are provided above the placement plate through an installation mechanism. A reciprocating screw is rotatably provided inside the protective cover. A screw sleeve is fitted outside the reciprocating screw. A dust suction hood for absorbing exhaust gas is provided inside the protective cover. The dust suction hood is fixedly installed outside the screw sleeve. An exhaust pipe is provided on the dust suction hood. A movable port that cooperates with the exhaust pipe is opened on the protective cover.

[0007] Preferably, the fixing mechanism includes a fixing plate fixedly connected to the outer wall of the crossbar, and the fixing plate is connected to the support frame by fixing bolts.

[0008] Preferably, the moving mechanism includes a moving nut threaded onto the outer wall of the moving screw, a transmission gear fixedly provided at one end of the processing roller, the transmission gear being rotatably connected to the moving nut, and a drive gear meshing with the transmission gear fixedly provided at the end of the output shaft of the drive motor.

[0009] Preferably, the movable mechanism includes an electric slide rail disposed in the movable groove, a support rod is fixedly provided on the outer wall of the welding ring, and a slider that cooperates with the electric slide rail is fixedly provided at the end of the support rod. The movable groove and the slider are both T-shaped in vertical section.

[0010] Preferably, the connecting mechanism includes a lifting nut threaded onto the outer wall of the lifting screw, and the outer wall of the placement plate is fixedly connected to the arc-shaped outer wall of the lifting nut.

[0011] Preferably, the rotating mechanism includes pulleys fixedly mounted on the outer walls of two lifting screws, and the two pulleys are connected by a connecting belt.

[0013] Preferably, both the support frame and the support plate have openings, and the protective cover has an L-shaped side sectional view.

[0014] The beneficial effects of this invention are:

[0015] 1. By setting up a protective cover, and installing a dust collection hood inside the protective cover, and setting up a reciprocating screw to work with it, the processing exhaust gas can be absorbed and treated during the processing by means of a easily movable dust collection hood. It has a certain range of movement to ensure the dust collection effect and avoid the direct emission of exhaust gas, which will affect the environment and operators.

[0016] 2. By setting up fixed mechanisms, movable mechanisms, and installation mechanisms, and with the help of components such as fixed bolts, movable bolts, and installation bolts, convenient disassembly and installation are achieved between components such as the crossbar and the support frame, the placement plate and the winding roller, and the placement plate and the protective cover, ensuring the ease of use of the device.

A power device (motor) connected to the movable screw 21 is provided in the movable groove 20. This power device can drive the movable screw 21 to rotate.

[0028] A drive motor 13 is provided above the crossbar 1. A welding ring 14 is welded to the outside of the drive motor 13. A movable groove 19 is provided on the upper end face of the crossbar 1. The welding ring 14 cooperates with the movable groove 19 through a movable mechanism. The movable mechanism includes an electric slide rail set in the movable groove 19. A support rod 16 is fixedly provided on the outer wall of the welding ring 14. A slider that cooperates with the electric slide rail is fixed at the end of the support rod 16. The vertical section of the movable groove 19 and the slider are both T-shaped. The electric slide rail and the slider, together with the support rod 16 and the welding ring 14, enable the convenient movement of the drive motor 13.

[0029] A support plate 3 is fixedly installed on the bottom wall of the crossbar 1. The support plate 3 is L-shaped and has two lifting grooves 22. Lifting screws 23 are rotatably installed in both lifting grooves 22. A placement plate 4 is provided below the processing roller 9. The placement plate 4 is connected to the two lifting screws 23 through a connecting mechanism. The connecting mechanism includes a lifting nut 24 threaded onto the outer wall of the lifting screw 23. The outer wall of the placement plate 4 is fixedly connected to the arc-shaped outer wall of the lifting nut 24. The placement plate 4 can achieve lifting operation with the help of the lifting screws 23 and the lifting nut 24 assembly. Limiting rods are provided in both the lifting groove 22 and the moving groove 20. The limiting rods slide through the lifting nut 24 and the moving nut respectively to achieve the limiting function.

[0030] The support plate 3 is equipped with a transmission chamber. The ends of the lifting screws 23 extend into the transmission chamber and are connected and cooperated through a rotating mechanism. The rotating mechanism includes pulleys 25 fixedly installed on the outer walls of the two lifting screws 23. The two pulleys 25 are connected by a connecting belt 27. The lifting motor 26 can directly drive one of the lifting screws 23 to rotate. The lifting screw 23 can drive the other lifting screw 23 to rotate with the help of the pulleys 25 and the connecting belt 27.

[0031] The bottom wall of the transmission chamber is equipped with a lifting motor 26 that is connected to one of the lifting screws 23. Two winding rollers 10 are installed above the placement plate 4 through an installation mechanism. The installation mechanism includes a connecting rod 5 connected to the placement plate 4 by mounting bolts. One end of the winding roller 10 is rotatably connected to the outer wall of the connecting rod 5. The protective cover 6 is fixedly connected to the outer wall of the other side of the connecting rod 5. The installation bolts and the connecting rod 5 enable the convenient disassembly and installation of components such as the protective cover 6 and the winding roller 10.

[0032] A reciprocating lead screw 12 is rotatably installed inside the protective cover 6, and a lead screw sleeve is fitted outside the reciprocating lead screw 12. A dust suction hood 11 for absorbing exhaust gas is installed inside the protective cover 6. The dust suction hood 11 is fixedly installed outside the lead screw sleeve. An exhaust pipe 8 is provided on the dust suction hood 11. A movable port 7 that cooperates with the exhaust pipe 8 is opened on the protective cover 6. The exhaust gas is absorbed by the exhaust equipment in conjunction with the exhaust pipe 8 and the dust suction hood 11. The exhaust gas is absorbed into the storage device for storage or filtered before being discharged to avoid environmental impact. The storage, filtration and exhaust equipment are common equipment components in the prior art, and will not be described in detail here.

[0033] Both the support frame 2 and the support plate 3 have openings. The protective cover 6 has an L-shaped side section. By opening the support frame 2 and the placement plate 4, the weight of the components is reduced, thereby reducing the difficulty of handling the entire device. At the same time, it saves the materials used for the components and reduces the overall cost of the equipment.

[0034] In use, the transfer film is wound around two winding rollers 10 and positioned below the processing roller 9. One of the connecting rods 5 has a winding motor connected to one of the winding rollers 10. The winding motor can drive the winding roller 10 to rotate, thereby winding and collecting the transfer film. The winding roller 10 winds and collects the processed transfer film. The processing component is laid flat on the upper surface of the placement plate 4 and positioned below the transfer film. Starting the drive motor 13 can drive the drive gear 15 to rotate. The drive gear 15, in conjunction with the transmission gear meshing with it, can drive the processing roller 9 to rotate. The electric slide rail and the moving screw 21 work together to achieve synchronous movement of the drive motor 13 and the processing roller 9. At the same time, the drive motor 13 can drive the processing roller 9 to rotate with the help of the drive gear 15 and the transmission gear, thereby achieving the rotational processing operation of the transfer film and the processing component.

[0035] During the processing, exhaust equipment such as a negative pressure pump is used in conjunction with the exhaust pipe 8 and the dust hood 11 to absorb and treat the exhaust gas, preventing it from spreading into the air and causing impact or harm to the environment and surrounding operators. The power component (motor type) can drive the reciprocating screw 12 to rotate. When the reciprocating screw 12 rotates, the screw sleeve on its outer wall can drive the dust hood 11 to move within the protective cover 6, realizing the absorption and treatment of exhaust gas in multiple areas and ensuring the absorption effect of exhaust gas.

[0036] Among them, the lifting screw 23 can drive the placement plate 4 to lift and lower, which facilitates the contact or separation of the processing parts with the processing roller 9 and the transfer film. When it is at a low position, it is also convenient to put the processing parts in. At the same time, the winding roller 10 and the protective cover 6 are also convenient for the placement plate 4 and the connecting rod 5 to be disassembled and installed, resulting in high overall convenience.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
