Description

Technical Field

[0001] This utility model belongs to the field of hot stamping rollers, specifically relating to a structure for an oil-proof, electrically heated hot stamping roller for a hot stamping machine. Background Technology

[0002] The hot stamping rollers used in hot stamping machines, commonly known as hot stamping rollers, are a crucial component in the hot stamping process. Hot stamping is a printing and decorative technique that uses a hot stamping machine to transfer metal foil (such as gold foil, silver foil, copper foil, etc.) with patterns or text onto the surface of printed materials or other items to create a bright decorative effect.

[0003] Traditional hot stamping rollers typically have a heating element installed inside the roller body to heat the heat transfer oil. This design may result in uneven heat distribution, with the center overheating while the edges are underheated, leading to inconsistent hot stamping effects. Furthermore, the heating element is difficult to maintain and replace, requiring disassembly of the hot stamping roller, which increases maintenance costs and downtime.

[0004] Therefore, we propose a leak-proof, electrically heated hot stamping roller structure for hot stamping machines to solve the above problems. Utility Model Content

[0005] To address the issues of uneven heat distribution and difficulty in maintaining and replacing heating devices that arise from the installation of heating devices inside the roller body in traditional hot stamping rollers, this invention provides a leak-proof, electrically heated hot stamping roller structure for hot stamping machines.

[0006] The solution adopted by this utility model to solve its technical problem is: a leak-proof electric heating roller structure for a hot stamping machine, including a hot stamping roller, a single-pass rotary joint, a double-pass rotary joint, and an electric heating tube, with sealing shafts installed at both ends of the hot stamping roller.

[0007] The double-pass rotary joint is connected to the sealing shaft on the left, and its flow channel communicates with the inner cavity of the sealing shaft on the left.

[0008] A quick-release connector 2 is installed at the lower interface of the double-port rotary joint, and an oil inlet pipe is installed at the bottom of the quick-release connector 2.

[0009] The heating element is installed at the left end of the double-pass rotary joint, and its heating element extends into the flow channel of the double-pass rotary joint.

[0010] The single-pass rotary joint is connected to the sealing shaft on the right, and its flow channel is connected to the inner cavity of the sealing shaft on the right.

[0011] A quick-release connector is installed at the lower interface of the single-pass rotary joint, and a return oil pipe is installed at the bottom of the quick-release connector.

[0012] Preferably, the heating element is provided with an aviation plug.

[0013] Preferably, it also includes an oil tank and an oil pump, with the oil pump's suction pipe inserted into the oil tank, its outlet end connected to the oil inlet pipe, and the lower end of the return pipe connected to the oil filling port of the oil tank.

[0014] Preferably, a temperature sensor transmitter is installed inside the oil tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model heats the heat-conducting oil entering the hot stamping roller directly through an electric heating tube, which can more effectively transfer heat to the entire roller surface, helping to improve the hot stamping quality and reduce defective products caused by temperature fluctuations. In addition, the electric heating tube is set on the outside of the hot stamping roller, making maintenance and replacement relatively convenient. It does not require disassembling the hot stamping roller, reducing maintenance costs and downtime. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 This utility model provides a technical solution for an oil-leakage-proof electrically heated hot stamping roller structure for a hot stamping machine:

[0021] Example 1:

[0022] according to Figure 1 As shown, it includes a heating roller 1, a single-pass rotary joint 2, a double-pass rotary joint 3, and an electric heating tube 61. Sealing shafts 11 are installed at the left and right ends of the heating roller 1, respectively. The sealing shafts 11 are installed in the bearing seats to support the heating roller 1 and make the heating roller 1 stable during rotation.

[0023] The double-pass rotary joint 3 is connected to the left sealing shaft 11, and its flow channel is connected to the inner cavity of the left sealing shaft 11, so that the heat transfer oil enters the heating roller 1 through the double-pass rotary joint 3 and the left sealing shaft 11.

[0024] A quick-release connector 2 31 is installed at the lower interface of the double-port rotary joint 3. An oil inlet pipe 5 is installed at the bottom of the quick-release connector 2 31. By setting the quick-release connector 2 31, it is easy to quickly separate the oil inlet pipe 5 from the double-port rotary joint 3.

[0025] The heating element 61 is equipped with an aviation plug 62, which facilitates the quick disconnection of the power cord from the heating element 61, making it easier to maintain and replace the heating element 61.

[0026] The heating element 61 is installed at the left end of the double-pass rotary joint 3. Its heating element extends into the flow channel of the double-pass rotary joint 3. The heating element 61 directly heats the heat-conducting oil entering the hot stamping roller 1, which can more effectively transfer heat to the entire roller surface, help improve the hot stamping quality, reduce defective products caused by temperature fluctuations, and the heating element 61 is set outside the hot stamping roller 1, making maintenance and replacement relatively convenient. It does not require disassembling the hot stamping roller 1, reducing maintenance costs and downtime.

[0027] The single-pass rotary joint 2 is connected to the right sealing shaft 11, and its flow channel is connected to the inner cavity of the right sealing shaft 11, so that the heat-conducting oil in the heating roller 1 flows out through the right sealing shaft 11 and the single-pass rotary joint 2.

[0028] A quick-release connector 21 is installed at the lower interface of the single-way rotary joint 2. A return oil pipe 4 is installed at the bottom of the quick-release connector 21. By setting the quick-release connector 21, it is easy to quickly separate the return oil pipe 4 from the single-way rotary joint 2.

[0029] Example 2:

[0030] Based on Embodiment 1, the difference is as follows: it also includes an oil tank and an oil pump. The oil pump's suction pipe is inserted into the oil tank, and its oil outlet is connected to the oil inlet pipe 5. The oil pump draws out the heat transfer oil from the oil tank and pumps it into the double-pass rotary joint 3 through the oil inlet pipe 5.

[0031] The lower end of the return oil pipe 4 is connected to the oil filling port of the oil tank, so that the heat-conducting oil flowing out of the heating roller 1 flows back into the oil tank.

[0032] A temperature sensor transmitter is installed inside the oil tank to monitor the temperature of the heat transfer oil in real time, so as to adjust the temperature of the heat transfer oil in the tank in a timely manner and control the temperature of the heat transfer oil in the tank.
